Resumo Abundam os relatórios sobre Lernaea parasitando o estoque de cria, alevinos e espécies de peixes de água doce cultiváveis de tamanho comercial em várias partes do mundo. Investigamos sete fazendas de aquicultura de pequena escala e de que maneira a Lernaea predominante está impactando-as. Aleatoriamente, sete fazendas de peixes foram selecionadas para determinar a porcentagem de prevalência de ectoparasitas de Lernaea. Foram recolhidas informações relevantes sobre os viveiros de peixes para estimar os vários aspectos, tais como efeitos da fonte e qualidade da água, alimentação, densidade de povoamento, tratamento utilizado e peso e comprimento dos peixes, relacionados com a infestação e prevalência de Lernaea. Os resultados indicaram que Catla catla (F. Hamilton, 1822) apresentou maior prevalência (41,7%) entre as sete espécies de peixes, enquanto Oreochromis niloticus apresentou zero. Outras cinco espécies de peixes Ctenopharyngodon idella, Cirrhinus cirrhosis, Cyprinus carpio, Labeo rohita e Hypophthalmichthys molitrix apresentaram 13,2%, 8,1%, 7,7%, 7,4%, 0,9% de prevalência, respectivamente. Em Royal Fish Farm, 84,3% de infestação de Lernaea foi observada, enquanto não se observou nenhum parasita na fazenda de peixes Chunnian de Vicent. A fonte de água, qualidade, ração, fertilizantes, densidade de estocagem, temperatura da água e opções de tratamento potenciais exibiram tendências variadas entre as fazendas de peixes e prevalência. Dependendo do peso e comprimento, a maior prevalência (56,7% e 66,7%) foi observada nos grupos de 3501-4000 g e 81-90 cm. A taxa de infestação variou em várias partes do corpo dos peixes, sendo a nadadeira dorsal o órgão mais vulnerável e apresentou 2,3% de prevalência geral (enquanto 18,4% de contribuição dentro do total de 12,6% de infestação). Das 147 amostras de peixes infectados, 45 estavam amplamente contaminadas pela propagação de Lernaea. Em conclusão, nossos resultados confirmam que Lernaea pode representar uma ameaça considerável para peixes comercializáveis, e várias opções de tratamento devem ser educadas para os agricultores para ajudar a mitigar a propagação e as perdas potenciais. Além disso, Catla catla é mais vulnerável à infestação por Lernaea (41,7%), assim como as espécies de peixes sendo cultivadas em densidades de estocagem mais altas.

Abstract Reports abound on Lernaea parasitizing the brood stock, fingerlings, and marketable-sized culturable freshwater fish species in various parts of the world. We investigated seven small-scale aquaculture farms and how the prevailing Lernaea is impacting them. Randomly seven fish farms were selected to determine the prevalence percentage of lernaeid ectoparasites. Relevant information of the fishponds to estimate the various aspects such as effects of water source and quality, feed, stocking density, treatment used, and weight and length of fish, concerned with Lernaea infestation and prevalence was gathered. The results indicated that Catla catla (F. Hamilton, 1822) showed highest prevalence (41.7%) among the seven fish species, whereas Oreochromis niloticus showed zero. Other five fish species Ctenopharyngodon idella, Cirrhinus cirrhosis, Cyprinus carpio, Labeo rohita and Hypophthalmichthys molitrix showed 13.2%, 8.1%, 7.7%, 7.4%, 0.9% prevalence, respectively. In Royal Fish Farm 84.3% lernaeid infestation was observed, while no parasite was observed in the Vicent’s Chunnian fish farm. The water source, quality, feed, fertilizers, stocking density, water temperature, and potential treatment options displayed varying tendencies among fish farms and prevalence. Depending on the weight and length, the highest prevalence (56.7%, and 66.7%) was observed in 3501-4000 g and 81-90 cm groups. The infestation rate varied in various fish body parts with the dorsal fin the most vulnerable organ and showed 2.3% overall prevalence (while 18.4% contribution within total 12.6% infestation). Out of 147 infected fish samples, 45 were extensively contaminated by Lernaea spread. In conclusion, our findings confirm that Lernaea could pose a considerable threat to marketable fish, and various treatment options should be educated to the farmers to help mitigate the spread and potential losses. Furthermore, Catla catla is more vulnerable to Lernaea infestation (41.7%), so are the fish species being cultured at higher stocking densities.

Resumo O crescimento das plantas é severamente reduzido devido ao estresse hídrico, afetando a fotossíntese, incluindo a atividade do fotossistema II (PSII) e o transporte de elétrons. Este estudo enfatizou as mudanças comparativas e prioritárias na atividade do PSII devido à seca progressiva em sete populações de Panicum antidotale (P. antidotale) coletadas no Deserto do Cholistão e regiões fora do Cholistão. Perfilhos de igual crescimento de sete populações de P. antidotale cultivadas em vasos de plástico cheios de solo foram submetidos à seca progressiva, retendo a irrigação com água por três semanas. A seca progressiva reduziu o teor de umidade do solo, teor de água relativo nas folhas, pigmentos fotossintéticos e biomassa fresca e seca dos brotos em todas as sete populações. Populações de Dingarh Fort, Dingarh Grassland e Haiderwali tiveram maior crescimento do que as de outras populações. As populações de Cholistani, especialmente em Dingarh Grassland e Haiderwali, apresentaram maior capacidade de ajuste osmótico, refletido pelo potencial osmótico e maior acúmulo de proteínas solúveis totais. H2O2 máximo sob estresse hídrico foi observado em populações de Muzaffargarh e Khanewal, mas estas foram intermediárias no conteúdo de MDA. Sob estresse hídrico, as populações de Muzaffargarh e Dingarh Fort tiveram maior acúmulo de K+ em suas folhas. Durante a seca progressiva, as populações não cholistanesas mostraram rolagem completa das folhas após 23 dias de seca, e essas populações não conseguiram suportar mais condições de estresse hídrico, enquanto as populações cholistani toleraram mais condições de estresse hídrico por 31 dias. Além disso, a seca progressiva causou danos ao PSII após 19 dias e tornou-se severa após 23 dias em populações não cholistanesas de P. antidotale do que em populações cholistanesas.

Abstract Growth of plants is severely reduced due to water stress by affecting photosynthesis including photosystem II (PSII) activity and electron transport. This study emphasised on comparative and priority targeted changes in PSII activity due to progressive drought in seven populations of Panicum antidotale (P. antidotale) collected from Cholistan Desert and non-Cholistan regions. Tillers of equal growth of seven populations of P. antidotale grown in plastic pots filled with soil were subjected progressive drought by withholding water irrigation for three weeks. Progressive drought reduced the soil moisture content, leaf relative water content, photosynthetic pigments and fresh and dry biomass of shoots in all seven populations. Populations from Dingarh Fort, Dingarh Grassland and Haiderwali had higher growth than those of other populations. Cholistani populations especially in Dingarh Grassland and Haiderwali had greater ability of osmotic adjustment as reflected by osmotic potential and greater accumulation of total soluble proteins. Maximum H2O2 under water stress was observed in populations from Muzaffargarh and Khanewal but these were intermediate in MDA content. Under water stress, populations from Muzaffargarh and Dingarh Fort had greater K+ accumulation in their leaves. During progressive drought, non-Cholistani populations showed complete leaf rolling after 23 days of drought, and these populations could not withstand with more water stress condition while Cholistani populations tolerated more water stress condition for 31 days. Moreover, progressive drought caused PSII damages after 19 days and it became severe after 23 days in non-Cholistani populations of P. antidotale than in Cholistani populations.

Resumo Frangos de corte Hubbard com 320 dias de idade foram alocados aleatoriamente em quatro tratamentos (8 repetições, 10 aves/curral) e foram criados em condições de manejo padrão. As aves do primeiro grupo serviram como controle e foram alimentadas com uma dieta à base de milho, enquanto as aves dos três grupos restantes, ou seja, A, B e C, foram alimentadas com dieta basal suplementada com nanopartículas de cobre (CuNP) a 5, 10 e 15 mg/kg de dieta, respectivamente, por 35 dias. A suplementação de CuNP aumentou linearmente (P ≤ 0,05) o peso corporal (PC), o ganho de peso médio diário (GPDA) e o consumo de ração (FI) em frangos de corte. O ácido úrico, os níveis de glicose no sangue e a conversão alimentar (TCF) reduziram linearmente (P ≤ 0,05) com a suplementação de CuNP na dieta. A suplementação de CuNP na dieta também aumentou linearmente (P ≤ 0,05) peso, comprimento, diâmetro, índice peso/comprimento (P/L) e índice tibiotársico (índice TT) da tíbia. A inclusão de CuNP na dieta de frangos de corte aumentou linearmente os parâmetros medidos de músculo, ou seja; pH, diâmetro da fibra, área da seção transversal da fibra, diâmetro do fascículo, área da seção transversal do fascículo (P ≤ 0,05). A concentração de cobre, ferro, cálcio e fósforo no sangue também aumentou linearmente (P ≤ 0,05) com a suplementação de CuNP. No geral, CuNP afetou positivamente o desempenho de crescimento, características histológicas dos músculos, resistência óssea e metabólitos séricos em frangos de corte.

Abstract Three hundred and twenty day old Hubbard broilers were randomly allocated to four treatments (8 replicates, 10 birds/pen) and were raised under standard management conditions. Birds in the first group served as control and were fed a corn based diet, while birds in the remaining three groups i.e.; A, B and C were fed with a basal diet supplemented with copper nanoparticles (CuNP) at 5, 10 and 15 mg /kg of diet respectively for 35 days. Supplementation of CuNP linearly increased (P≤0.05) body weight (BW), average daily weight gain (ADWG) and feed intake (FI) in broilers. Uric acid, glucose levels in blood and feed conversion ratio (FCR) reduced linearly (P≤0.05) with CuNP supplementation in diet. Supplementation of CuNP in the diet also linearly increased (P≤0.05) tibia weight, length, diameter, weight/length index (W/L) and Tibiotarsal index (TT index). Inclusion of CuNP in broilers diet linearly increased the measured parameters of muscle i.e.; pH, fiber diameter, fiber cross-sectional area, fascicle diameter, fascicle cross-sectional area (P≤0.05). Concentration of copper, iron, calcium and phosphorous in blood also increased line-arly (P ≤ 0.05) with CuNP supplementation. Overall, CuNP positively affected the growth performance, histological characteristics of muscles, bone strength and serum metabolites in broilers.

ABSTRACT Purpose: This study aimed to determine the effect of serum G receptor-mediated protein-1 levels on the development of retinopathy in patients with diabetes in comparison with healthy individuals. Methods: The study enrolled patients with diabetic retinopathy (Group 1), patients without diabetic retinopathy (Group 2), and healthy individuals (Group 3). Levels of serum progesterone, serum G receptor-mediated protein-1, estradiol, oxidant/antioxidants, and thyroid-releasing hormones were analyzed and compared among the groups. Post-hoc analysis was performed to compare the subgroups in which significant differences were found. Results: Groups 1, 2, and 3 each included 40 patients. A significant difference was found among all groups in terms of serum G receptor-mediated protein-1, oxidant/antioxidant, and estradiol levels (p<0.01), but no significant difference was found in terms of thyroid-releasing hormone or progesterone (p=0.496, p=0.220, respectively). In the post-hoc analysis of the groups with significant differences, another significant difference was found among all groups for serum G receptor-mediated protein-1 and oxidant/antioxidant levels (p<0.05). Serum G receptor-mediated protein-1 and oxidant levels were positively correlated, whereas serum G receptor-mediated protein-1 and antioxidant levels were negatively correlated (r=0.622/p<0.01, r=0.453/p<0.01, r=0.460/p<0.01, respectively). The multiple regression analysis showed that increased levels of serum G receptor-mediated protein-1 may help prevent diabetic retinopathy. Conclusions: Serum G receptor-mediated protein-1 levels, which were the highest in the diabetic retinopathy Group, increased as the oxidant/antioxidant balance changed in favor of oxidative stress. This appears to be a defense mechanism for preventing neuronal damage.

RESUMO Objetivo: Esta pesquisa buscou determinar o impacto dos níveis de proteína G sérica no desenvolvimento da retinopatia em pacientes diabéticos, comparando-os a indivíduos saudáveis. Métodos: Foram incluídos, no estudo, 40 pacientes com retinopatia diabética (Grupo 1), 40 pacientes sem retinopatia diabética (Grupo 2) e 40 indivíduos saudáveis (Grupo 3). Os níveis hormonais de progesterona sérica, de proteína G sérica, estradiol, oxidante/antioxidante e hormônio liberado pela tireoide foram analisados e comparados. A análise post hoc foi realizada para comparar os subgrupos nos quais diferenças estatisticamente significativas foram encontradas. Resultados: Uma diferença significativa foi encontrada entre todos os grupos em termos de proteína G sérica, oxidante/antioxidante e níveis de estradiol (p<0.01), mas nenhuma diferença significativa foi encontrada em termos de hormônio liberado pela tireoide ou progesterona (p=0,496, p=0,220, respectivamente). Na análise post hoc dos grupos com diferenças estatisticamente significativas, outra diferença significativa foi encontrada entre todos os grupos para proteína G sérica e níveis oxidantes/antioxidantes (p<0,05). Os níveis de proteína G sérica e os níveis de oxidante foram positivamente correlacionados, enquanto os níveis de proteína G sérica e os níveis de antioxidantes foram negativamente correlacionados (r=0,622/p<0,01, r=0,453/p<0,01, r=0,460/p<0,01, respectivamente). A análise de regressão múltipla mostrou que o aumento da proteína G sérica pode ajudar a prevenir a retinopatia diabética. Conclusões: Os níveis de proteína G sérica que eram mais altos no grupo de retinopatia diabética, aumentaram à medida que o equilíbrio oxidante/antioxidante mudou em favor do estresse oxidativo. Este parece ser um mecanismo de defesa para prevenir danos neuronais.

The study evaluated the solvent-free oxidation of 1-hexene utilizing supported ruthenium catalysts and a small amount of terbutyl hydroperoxide (TBHP) as a radical initiator. The characteristics of the supported catalysts were characterized using transmission electron microscopy (TEM) and N2 adsorption-desorption isotherms. The results of the study revealed that 1% Ru/TiO2 had favorable catalytic performance when subjected to environmentally friendly reaction conditions. This behavior was thought to be a result of Ru spreading and loading on the TiO2. To obtain optimal reaction parameters, the catalyst manufacturing process, temperature, reaction time, type of support, and activating amount were tuned. Compared to catalysts generated using wet-impregnation and precipitation techniques, those produced using sol-immobilization have greater activity.

Internet-based religious learning has presented a new face to the diversity of Muslim youth. This article aims to analyse and evaluate Muslim youth's understanding, attitudes, and religious practices and demonstrate the impact of internet-based Islamic learning. As many as 23 Muslim youths in Jepara, Central Java, aged 17-20 years, became the informants of this study. Data were collected through in-depth interviews and observations. Further research data were analysed descriptively and interpretatively. This study found that most Muslim youths who studied Islam online experienced confusion and emptiness in religion caused by an incomplete learning process. Most Muslim youths do not have solid theological views, pseudo-worship practices and weak religious ideologies. This study suggests that teenagers acquire essential Islamic knowledge from credible sources such as kyai with clear scientific credentials. This foundation enables them to discern reliable Islamic content in cyberspace, safeguarding against distortions in their understanding of Islam and spirituality. CONTRIBUTION: This research provides a more comprehensive understanding of the complexities of the impact of internet-based learning on the diverse experiences of Muslim youth. Although the internet has the potential to be an invaluable source of knowledge, the challenges of integrating information with traditional understanding require serious attention

Abstract The aim of this study was to determine the effects of flavonoid, which is a product of citrus production, on blood parameters and HSP 70 concentration in quails applied at thermoneutral and heat stress. In this study, 160 quails (Coturnix coturnix japonica, male), 6 wk old and 150-200 g live weight, were housed in cages for 1 wk of exercise and 5 wk of trial period. The study design consists of 4 groups of 40 animals and 4 subgroups with 10 animals in each group. Thermoneutral (24 ± 0.1 o C) groups are NC (0 g hesperidin/kg basal feed) and NHES3 (3 g hesperidin /kg basal feed) and heat stress (34 ± 0.1 oC) groups are HC (0 g hesperidin/kg basal feed) and HHES3 (3 g hesperidin /kg basal feed) were randomly generated. In the case of heat stress, pO2, pH, HCO3, Cl concentrations decreased in the HHES3 group compared to the HC group (P<0.05). ALP enzyme concentration showed a significant decrease in the HHES3 group compared to the HC group in the heat stress condition. Heat shock protein (HSP70) protein level increased in blood serum, kidney, liver and thigh tissues in HC group with cellular stress during heat stress; however, HSP70 concentration decreased significantly in the HHES3 group. As a result, positive effects of hesperidin supplementation in the diet were found in both heat stress and thermoneutral conditions.

Resumen El objetivo de este estudio fue determinar los efectos del flavonoide, que es un producto de la producción de cítricos, sobre los parámetros sanguíneos y la concentración de HSP70 en codornices aplicado en condiciones termoneutrales y de estrés por calor. En este contexto, 160 codornices (Coturnix coturnix japonica, macho), de 6 semanas de edad y 150-200 g de peso vivo, se alojaron en jaulas durante 1 semana de ejercicio y 5 semanas de período de ensayo. El diseño del estudio constó de 4 grupos de 40 animales y 4 subgrupos con 10 animales en cada grupo. La agrupación se realizó en forma de 2x2. Los grupos termoneutrales (24 ± 0.1 °C) son NC (0 g de hesperidina/kg de alimento base) y NHES3 (3 g de hesperidina/kg de alimento base) y los grupos bajo estrés por calor (34 ± 0.1 °C) son HC (0 g de hesperidina/kg de alimento base) y HHES3 (3 g de hesperidina/kg de alimento base), y se generaron aleatoriamente. En el caso de estrés por calor, las concentraciones de pO2, pH, HCO3 y Cl disminuyeron en el grupo HHES3 en comparación con el grupo HC (P<0.05). La concentración de enzimas ALP mostró una disminución significativa en el grupo HHES3 en comparación con el grupo HC en la condición de estrés por calor. El nivel de proteínas de choque térmico (Hsp70) aumentó en el suero sanguíneo, tejidos del riñón, hígado y pecho en el grupo HC con estrés celular durante el estrés por calor; sin embargo, la concentración de Hsp70 disminuyó significativamente en el grupo HHES3. Como resultado, se encontraron efectos positivos de la suplementación con hesperidina en la dieta tanto en condiciones de estrés por calor como en termoneutrales.

Resumen La hesperidina es un flavonoide derivado de los cítricos con usos potenciales en la alimentación animal. Se investigaron los efectos de la suplementación con hesperidina en dietas para codorniz japonesa (Codornix codornix japonica) sobre la química sanguínea, los niveles de enzimas antioxidantes en ciertos tejidos, la histomorfología intestinal y la microflora fecal. Se llevó a cabo un ensayo de alimentación durante 35 días utilizando 300 codornices. Se dividieron en tres tratamientos según la dieta administrada: Control (0 g de hesperidina/kg de alimento); HES1 (1 g de hesperidina/kg de alimento); y HES2 (2 g de hesperidina/kg de alimento). En cada tratamiento se llevaron a cabo cinco réplicas de veinte animales cada una. Al final del periodo de estudio, se tomaron muestras de heces, sangre, hígado y tejido muscular del muslo. En sangre, la alanina transaminasa (ALT) y la lactato deshidrogenasa (LDH) fueron más bajas en HES1 que en el Control, pero aumentaron en HES2 (P<0.05). La aspartato transaminasa (AST) en la sangre aumentó en HES1, pero disminuyó en HES2 (P<0.05). La amilasa aumentó tanto en HES1 como en HES2 (P<0.05). Las enzimas antioxidantes GSH, CAT y SOD en los tejidos aumentaron (P<0.05). En el ciego y el colon, los tratamientos con hesperidina produjeron vellosidades más altas y criptas menos profundas que en el Control (P<0.05). La presencia de la hesperidina en la dieta para codornices no afectó la microflora en las heces. La adición de la hesperidina mostró efectos positivos en los niveles de enzimas antioxidantes en lípidos, muslos, hígado y suero, sobre la histomorfología intestinal y en la microflora fecal.

Abstract This study was conducted to determine the effects of hesperidin, a flavonoid added to quail diets, on blood serum, enzymes in tissues, intestinal histomorphology and fecal microflora. In the study, first treatment [(control) (0g hesperidin/kg feed)], second treatment [(HES1) (1 g hesperidin/kg feed)], third treatment [(HES2) (2 g hesperidin/kg feed)] was added to with the basal diet through 35 d. The study was carried out with 3 main groups, 20 quails with 5 sub-repeats in each group and a total of 300 quails. At the end of the study, blood, liver and thigh muscle tissue and fecal samples were taken. Alanine transaminase (ALT) and lactate dehydrogenase (LDH) decreased in the HES1 group but increased in the HES2 group compared to the control group (P<0.05). Aspartate transaminase (AST) increased in the HES1 group compared to the control group and decreased in the HES2 group (P<0.05). Amylase, on the other hand, showed a regular increase in HES1 and HES2 groups to which hesperidin was added to the control group in hesperidin added groups (P<0.05). The tissue antioxidant GSH, CAT and SOD enzyme parameters showed a significant increase in the hesperidin added groups compared to the control group, and this increase was found to be significant compared to the control group (P<0.05). In intestinal histomorphology, in hesperidin treatment groups increased the height of villus in the cecum tissue; in colon tissue, it was determined that hesperidin added groups increased villus height but decreased crypt depth (P<0.05). Consequently, diets hesperidin with treatments positively is thought to affect the lipid, thigh, liver and serum antioxidant enzyme levels, intestinal histomorphology and fecal microflora in quail.

Abstract Introduction Septorhinoplasty operates on the nose’s bone and cartilage and is ensued by severe postoperative pain. Objective The objective of this study is to evaluate the effects of preoperative administration of intravenous (IV) paracetamol and ibuprofen on postoperative pain scores in patients undergoing septorhinoplasty. Methods A total of 150 patients undergoing septorhinoplasty were randomly assigned into 3 groups with 50 patients in each group. The control group (group A) was administered 100 ml saline solution; the paracetamol group (group B) was administered 1,000 mg of IV paracetamol in 100 ml of saline solution; and the ibuprofen group (group C) was administered 800 mg of IV ibuprofen in 100 ml of saline solution before surgery. Opioid analgesics were employed to achieve postoperative analgesia. Postoperative pain was evaluated using the visual analogue scale (VAS). Postoperative opioid consumption and adverse effects were also recorded for each patient. Results In comparison with group A, the score in the VAS of groups B and C was statistically lower in all the time intervals (p < 0.05). In the 1st and 6th hours postoperatively, group C’s score in the VAS in was lower than that of group B (p < 0.05). In the control group, total opioid consumption was highest in all time intervals (p < 0.05). In group C, total opioid consumption was significantly lower than in group B in the 0 to 6 and 6 to 12 hours intervals. (p < 0.05). Conclusion The single-dose preemptive administration of ibuprofen has a more profound postoperative analgesic effect than paracetamol in the first 6 hours after septorhinoplasty. After the first 6 hours postsurgery, there is no difference between ibuprofen and paracetamol in terms of analgesic effect.

RESUMEN: La isquemia renal es una de los motivos del daño renal agudo. Sin embargo, los enfoques protectores y terapéuticos para este problema son limitados. La diacereína es un fármaco antiinflamatorio caracterizado por numerosas actividades biológicas. Nuestro objetivo fue determinar el impacto de mejora de la diacereína en la condición de lesión por isquemia/ reperfusión renal (I/R), explorando los mecanismos subyacentes. Veinticuatro ratas macho se distribuyeron en cuatro grupos (n= 6): grupo simulado; grupo de diacereína (DIA); grupo I/R, en el que una pinza no aplastante ocluyó el pedículo renal izquierdo durante 45 min, y el riñón derecho fue nefrectomizado durante 5 min antes del proceso de reperfusión; Grupo I/R + diacereína, inyectado por vía intraperitoneal con 50 mg de diacereína/kg i.m. 30 min antes de la operación I/R. Se encontró que la isquemia/ reperfusión afecta la función renal e induce alteraciones histopatológicas. El análisis de citometría de flujo demostró una expresión elevada de células dendríticas innatas y maduras en tejidos renales I/R. Además, se observó una regulación positiva en la expresión de los genes inflamatorios (TLR4, Myd88 y NLRP3) y una sobreexpresión de las citoquinas proinflamatorias (IL-1β), marcadores apoptóticos (caspasa-3) y piroptóticos (caspasa-1) en animales con experiencia en I/R. Los deterioros antes mencionados fueron mitigados por el tratamiento previo a la diacereína I/R. La diacereína alivió la inflamación y la apoptosis inducidas por I/R. Por lo tanto, podría ser un agente protector prometedor contra I/R.

SUMMARY: One of the reasons for acute kidney damage is renal ischemia. Nevertheless, there are limited protective and therapeutic approaches for this problem. Diacerein is an anti-inflammatory drug characterized by numerous biological activities. We aimed to determine the ameliorative impact of diacerein on renal ischemia/reperfusion injury (I/R) condition, exploring the underlying mechanisms. Twenty-four male rats were allotted into four groups (n= 6): sham group; Diacerein (DIA) group; I/R group, in which a non-crushing clamp occluded the left renal pedicle for 45 min, and the right kidney was nephrectomized for 5 min before the reperfusion process; I/R + diacerein group, injected intraperitoneally with 50 mg diacerein/kg i.m 30 minutes prior to I/R operation. Ischemia/ reperfusion was found to affect renal function and induce histopathological alterations. The flow cytometry analysis demonstrated an elevated expression of innate and mature dendritic cells in I/R renal tissues. Moreover, upregulation in the expression of the inflammatory genes (TLR4, Myd88, and NLRP3), and overexpression of the pro-inflammatory cytokines (IL-1β), apoptotic (caspase-3) and pyroptotic (caspase-1) markers were observed in I/R-experienced animals. The aforementioned deteriorations were mitigated by pre-I/R diacerein treatment. Diacerein alleviated I/R-induced inflammation and apoptosis. Thus, it could be a promising protective agent against I/R.

RESUMEN: El objetivo de este estudio fue investigar si la administración de ácido bórico (BA) ejercería algún efecto protector frente a la posible nefrotoxicidad y hepatotoxicidad inducida por la exposición a acrilamida (ACR) en ratas. En nuestro estudio, utilizamos un total de 28 ratas que se dividieron en cuatro grupos iguales. Grupo 1: grupo control que no fue tratado. Grupo 2: grupo ACR al que se le administró ACR 50 mg/kg/día por vía intraperitoneal (i.p) durante 14 días. Grupo 3: grupo BA al que se le administró BA 200 mg/kg/día por sonda por vía peroral (p.o) durante 14 días. Grupo 4: grupo ACR+BA al que se administró BA simultáneamente con ACR. Las capacidades antioxidantes y oxidantes totales (TAS/TOS) se midieron en todos los grupos al final del experimento. Además, los especímenes obtenidos fueron evaluados con examen histopatológico. Los estudios demostraron que los grupos ACR y ACr+BA no fueron significativamente diferentes en términos del nivel hepático de TAS, mientras que el nivel de TOS fue mayor en el grupo ACR que en el grupo ACR+BA. Los grupos no mostraron ninguna diferencia significativa con respecto a los niveles renales de TAS y TOS. En el examen histopatológico del tejido hepático, la puntuación de lesión histopatológica del grupo ACR fue significativamente mayor que la de los otros grupos, mientras que fue significativamente menor en el grupo ACR+BA que en el grupo ACR. Nuestro estudio concluyó que el ácido bórico tiene un efecto protector contra la hepatotoxicidad inducida por acrilamida, pero no contra la nefrotoxicidad.

SUMMARY: To investigate if the administration of boric acid (BA) would exert any protective effect against possible nephrotoxicity and hepatotoxicity induced by the exposure to acrylamide (ACR) in rats. In our study, we used a total of 28 rats that were divided into four equal groups. Group 1: the control group which was not treated with any procedure. Group 2: the ACR group that was administered ACR 50 mg/kg/day via intraperitoneal (i.p) route for 14 days. Group 3: the BA group that was administered BA 200 mg/kg/ day via gavage via peroral (p.o) route for 14 days. Group 4: the ACR+BA group that was administered BA simultaneously with ACR. Total antioxidant and oxidant (TAS/TOS) capacities were measured in all groups at the end of the experiment. In addition, the specimens obtained were evaluated with histopathological examination. Studies showed that the ACR and ACr+BA groups were not significantly different in terms of hepatic TAS level while the TOS level was higher in the ACR group than the ACR+BA group. The groups did not show any significant difference regarding renal TAS and TOS levels. In the histopathological examination of the hepatic tissue, the histopathological injury score of the ACR group was significantly higher than those of the other groups whereas it was significantly lower in the ACR+BA group than the ACR group. Our study concluded that Boric acid had a protective effect against acrylamide- induced hepatotoxicity, but not against nephrotoxicity.

RESUMEN Introducción: La isquemia renal (I) puede desarrollarse debido a la disminución o interrupción del flujo sanguíneo al riñón en algunas condiciones clínicas como shock, sepsis y trasplante renal. El reabastecimiento de sangre al riñón se denomina reperfusión (R). Tanto la isquemia como los períodos de reperfusión pueden causar graves daños renales. Objetivos: Cuando examinamos la progresión molecular I/R, las moléculas antioxidantes como la vitamina A parecen agentes de tratamiento prometedores. El objetivo de este estudio fue investigar los efectos de la vitamina A sobre la lesión renal I/R. Material y Métodos: En el estudio, 40 ratas macho Sprague-Dawley se dividieron en 5 grupos (n=8) como: control, solo I/R, I/R+1000, I/R+3000 e I/R+9000 UI/kg de la Vitamina A. La vitamina A se administró a cada grupo durante 7 días por vía oral forzada. Al final del experimento se recolectaron muestras de sangre y tejido del riñón. A partir de muestras de sangre se determinaron los niveles de superóxido dismutasa (SOD), malondialdehído (MDA), catalasa (CAT), nitrógeno ureico en sangre (BUN) y creatinina (Cr). Las muestras de tejido se tiñeron con hematoxilina/eosina y los cambios en la histología renal se examinaron histopatológicamente y estereológicamente al microscopio de luz. Resultados: Los cambios histopatológicos causados por I/R disminuyeron con la administración de la vitamina A de manera dependiente de la dosis (p<0,05). La administración de la vitamina A disminuyó los niveles de MDA, aumentó las actividades de SOD y CAT (p<0,05). La dosis más eficaz entre los grupos del tratamiento fue de 9000 UI/kg. No hubo una diferencia significativa entre el grupo control y todos los demás grupos con respecto a las concentraciones de BUN y Cr. Conclusiones: Consiguientemente, la administración de la vitamina A, después de I/R renal, redujo el daño histológico y mejoró el estado antioxidante. Estos resultados mostraron que la vitamina A puede ser un agente promisorio en el tratamiento de la lesión renal aguda (LRA) inducida por I/R.

ABSTRACT Introduction: Renal ischemia (I) could develop due to decreased or ceased blood flow to the kidney in some clinical conditions such as shock, sepsis, and kidney transplantation. The re-supply of blood to the kidney is called reperfusion (R). Ischemia and reperfusion periods can cause severe kidney damage. Objectives: When we examined the I/R molecular progression, antioxidant molecules such as vitamin A seem promising treatment agents. This study aimed to investigate the effects of vitamin A on renal I/R injury. Material and Methods: In the study, 40 Sprague-Dawley male rats were divided into five groups (n=8): the control group, only I/R, I/R+1000, I/R+3000, and I/R+9000 IU/kg of Vitamin A groups. Vitamin A was administrated to each group for seven days via oral gavage. Blood and kidney tissue samples were collected at the end of the experiment. We took blood samples for Superoxide dismutase (SOD), malondialdehyde (MDA), catalase (CAT), blood urea nitrogen (BUN), and creatinine (Cr) levels, and determined their values. The tissue samples were stained with hematoxylin/eosin to examine the renal changes histopathologically and stereologically under a light microscope. Results: Histopathological changes caused by I/R were decreased with vitamin A administration in a dose-dependent manner (p<0.05). Vitamin A administration decreased MDA levels and increased SOD and CAT activities (p<0.05). The most effective dose among treatment groups was 9000 IU/kg. There was no significant difference between the controls and all other groups regarding BUN and Cr concentrations. Conclusions: Consequently, administration of vitamin A after renal I/R reduced the histological damage and ameliorated the antioxidant state. These results showed that vitamin A could be a promising agent in treating I/R-induced acute kidney injury.

We report here on the process and findings of a research prioritisation exercise for universal health coverage (UHC) in South Africa, conducted during the course of 2019. As plans to roll out National Health Insurance (NHI) gather momentum and we transition into a pandemic recovery phase, we believe that it is now time to revisit these priorities, while recognising that experiences with the COVID-19 pandemic have revealed new system challenges and strengths and introduced new priorities. The UHC research priority-setting methodology followed a stepwise process of collation of evidence, expert brainstorming and the development of a survey completed by 68 members of the Public Health Association of South Africa. Themes related to leadership and governance were ranked most highly, and with other priorities generated, provide an initial road map of knowledge needs that could guide individual institutions and commissioning by funding bodies. We further reflect on the importance of researcher-decision-maker dialogue and strengthening the contribution of health policy and systems research to policy and practice, especially as new reforms are implemented.
