Resumo O câncer é uma doença maligna fatal e sua crescente prevalência mundial exige a descoberta de biomarcadores moleculares mais sensíveis e confiáveis. Investigar o nível de expressão de GINS1 e seu valor prognóstico em cânceres humanos distintos, usando uma série de abordagens in silico em várias camadas, pode ajudar a estabelecê-lo como um potencial biomarcador de diagnóstico e prognóstico compartilhado de diferentes subtipos de câncer. O mRNA de GINS1, a expressão da proteína e a metilação do promotor foram analisados usando UALCAN e Human Protein Atlas (HPA), enquanto a expressão de mRNA foi posteriormente validada via GENT2. Os valores prognósticos potenciais de GINS1 foram avaliados por meio do plotter KM. Em seguida, o cBioPortal foi utilizado para examinar as mutações genéticas relacionadas ao GINS1 e as variações do número de cópias (CNVs), enquanto a análise de enriquecimento da via foi realizada usando DAVID. Além disso, uma análise correlacional entre a expressão de GINS1 e células imunes T CD8 + e a construção de uma rede de interação gene-droga foi realizada usando TIMER, CDT e Cytoscape. O GINS1 foi encontrado regulado negativamente em um único subtipo de câncer humano, enquanto comumente regulado positivamente em 23 outros subtipos diferentes. A regulação positiva de GINS1 foi significativamente correlacionada com a sobrevida global pobre (OS) de Carcinoma Hepatocelular de Fígado (LIHC), Adenocarcinoma de Pulmão (LUAD) e Carcinoma de Células Claras Renais de Rim (KIRC). O GINS1 também foi encontrado regulado positivamente em pacientes LIHC, LUAD e KIRC de diferentes características clínico-patológicas. A análise de enriquecimento de vias revelou o envolvimento de GINS1 em duas vias diversas, enquanto poucas correlações interessantes também foram documentadas entre a expressão de GINS1 e seu nível de metilação do promotor, nível de células imunes T CD8 + e CNVs. Além disso, também previmos poucos medicamentos que poderiam ser usados no tratamento de LIHC, LUAD e KIRC, regulando a expressão de GINS1. O perfil de expressão de GINS1 no estudo atual sugeriu que é um novo biomarcador de diagnóstico e prognóstico compartilhado de LIHC, LUAD e KIRC.

Abstract Cancer is a fatal malignancy and its increasing worldwide prevalence demands the discovery of more sensitive and reliable molecular biomarkers. To investigate the GINS1 expression level and its prognostic value in distinct human cancers using a series of multi-layered in silico approach may help to establish it as a potential shared diagnostic and prognostic biomarker of different cancer subtypes. The GINS1 mRNA, protein expression, and promoter methylation were analyzed using UALCAN and Human Protein Atlas (HPA), while mRNA expression was further validated via GENT2. The potential prognostic values of GINS1 were evaluated through KM plotter. Then, cBioPortal was utilized to examine the GINS1-related genetic mutations and copy number variations (CNVs), while pathway enrichment analysis was performed using DAVID. Moreover, a correlational analysis between GINS1 expression and CD8+ T immune cells and a the construction of gene-drug interaction network was performed using TIMER, CDT, and Cytoscape. The GINS1 was found down-regulated in a single subtypes of human cancer while commonly up-regulated in 23 different other subtypes. The up-regulation of GINS1 was significantly correlated with the poor overall survival (OS) of Liver Hepatocellular Carcinoma (LIHC), Lung Adenocarcinoma (LUAD), and Kidney renal clear cell carcinoma (KIRC). The GINS1 was also found up-regulated in LIHC, LUAD, and KIRC patients of different clinicopathological features. Pathways enrichment analysis revealed the involvement of GINS1 in two diverse pathways, while few interesting correlations were also documented between GINS1 expression and its promoter methylation level, CD8+ T immune cells level, and CNVs. Moreover, we also predicted few drugs that could be used in the treatment of LIHC, LUAD, and KIRC by regulating the GINS1 expression. The expression profiling of GINS1 in the current study has suggested it a novel shared diagnostic and prognostic biomarker of LIHC, LUAD, and KIRC.

Resumo As drogas antituberculose são relatadas como causadoras de hepatotoxicidade, ocasionando o aumento assintomático das enzimas hepáticas. As plantas hepatoprotetoras desempenham um papel importante na proteção do fígado. Este estudo investigou o potencial hepatoprotetor de Solanum lycopersicum em ratos que foram intoxicados com isoniazida e rifampicina (INH + RIF) para induzir hepatotoxicidade. Trinta ratos wistar albinos foram divididos em cinco grupos de seis animais cada. Os ratos do grupo 1 representaram o grupo controle, enquanto os ratos dos grupos II, III, IV e V receberam INH + RIF (75 + 150 mg/kg) por via oral, por sete dias consecutivos. Para o tratamento, os ratos do grupo III receberam silimarina, enquanto os animais do grupo IV e V receberam 40 mg/kg e 80 mg/kg de extrato de S. lycopersicum, respectivamente. Nos dias 0 e 8, foram coletadas amostras de sangue para análise de biomarcadores hepáticos. Os dados foram submetidos a teste unilateral (ANOVA) e post hoc de Bonferroni para análise estatística. A hepatotoxicidade induzida por INH + RIF resultou em elevação significativa das enzimas hepáticas séricas, incluindo aspartato aminotransferase (AST), alanina aminotransferase (ALT), fosfatase alcalina (ALP) e bilirrubina total, enquanto houve a diminuição do nível de albumina. O S. lycopersicum, na dose de 80 mg / kg, reduziu significativamente as enzimas hepáticas AST, ALT, ALP e bilirrubina, enquanto o nível de albumina aumentou de forma significativa. O tratamento não teve efeito significativo no peso corporal e hepático. A hepatotoxicidade induzida por drogas pode ser tratada de forma eficaz com S. lycopersicum na dose de 80 mg/kg.

Abstract Anti-tuberculosis drugs are reported to cause hepatotoxicity, which varies from asymptomatic rise of the hepatic enzymes. Hepatoprotective plants plays important role to protect liver. This study investigated the hepatoprotective potential of the Solanum lycopersicum in rats intoxicated with Isoniazid and Rifampicin (INH+RIF) to induce hepatotoxicity. Thirty wistar albino rats were divided into five groups of six animals each. Group 1 rats were kept control while groups II, III, IV and V were administered with INH+RIF (75+150 mg/kg) orally, for seven consecutive days. For treatment, rats in group III received silymarin while animals in group IV and V were provided with 40 mg/kg and 80 mg/kg of Solanum lycopersicum extract, respectively. On day 0 and 8th blood samples were collected for the analysis of hepatic biomarkers. The data were subjected to one-way ANOVA and Bonferroni’s post hoc test for statistical analysis. Hepatotoxicity induced by INH+RIF resulted in significant elevation of serum hepatic enzymes including Aspartate aminotransferase (AST), Alanine aminotransferase (ALT), Alkaline phosphatase (ALP), and total bilirubin while decreased the albumin level. The Solanum lycopersicum at dose of 80 mg/kg significantly reduced the hepatic enzymes AST, ALT, ALP and bilirubin while the albumin level was significantly increased. The treatment had non-significant effect on body and liver weight. Drug induced hepatotoxicity can be effectively treated with Solanum lycopersicum at 80 mg/kg dose.

Resumo Por ser o vetor do vírus do Nilo Ocidental e da falaríase, o controle de Culex quinquefasciatus Say é provavelmente essencial. O tratamento com inseticida sintético parece ser mais eficaz para o controle dos mosquitos vetores. No entanto, esses produtos são tóxicos para o meio ambiente e organismos não visados. Consequentemente, o controle ecológico dos mosquitos vetores é necessário. Nesse sentido, o inseticida botânico parece mais produtivo. Portanto, a presente pesquisa teve como objetivo investigar a eficácia do extrato metanólico e de várias frações, incluindo n-hexano, acetato de etila, clorofórmio e fração aquosa, obtidos do extrato metanólico de Ailanthus altissima (Mill.) Swingle, Artemisia scoparia Waldst. & Kit. e Justicia adhatoda L. usando funil de separação contra os estágios larval, pupal e adulto de C. quinquefasciatus. As larvas e pupas de C. quinquefasciatus foram expostas a várias concentrações (31,25-1000 ppm) de extrato metanólico, e suas frações por 24 horas de período de exposição. Para o bioensaio knock-down (bioensaio de impregnação de papel de filtro), diferentes concentrações do extrato metanólico e suas várias frações (ou seja, 0,0625, 0,125, 0,25, 0,5 e 1 mg / mL) foram aplicadas por um período de exposição de 1 hora. Os resultados foram analisados estatisticamente usando desvio padrão, análise Probit e regressão linear. Os valores de R2 de larvas, pupas e adultos variaram de 0,4 a 0,99. Os valores de LC50 (concentração que causa 50% de mortalidade) para larvas de terceiro estádio tardio após 24 horas de período de exposição variaram de 93-1856,7 ppm, enquanto os valores de LC90 variaram de 424-7635,5ppm. Os valores de LC50 para pupas variaram de 1326,7-6818,4 ppm e os valores de LC90 variaram de 3667,3-17427,9 ppm, respectivamente. O KDT50 variou de 0,30 a 2,8% e os valores de KDT90 variaram de 1,2 a 110,8%, respectivamente. Por fim, a espécie J. adhatoda pôde ser eficaz para controlar populações de mosquitos vetores.

Abstract Being vector of West Nile Virus and falariasis the control of Culex quinquefasciatus is likely to be essential. Synthetic insecticide treatment is looking most effective for vectors mosquito control. However, these products are toxic to the environment and non-target organisms. Consequently, ecofriendly control of vectors mosquito is needed. In this regard botanical insecticide is looking more fruitful. Therefore, the present research aimed to investigate the effectiveness of methanolic extract and various fractions, including, n-hexane, ethyl-acetate, chloroform, and aqueous fraction, obtained from methanolic extract of Ailanthus altissima, Artemisia scoparia, and Justicia adhatoda using separating funnel against larval, pupal, and adult stages of Culex quinquefasciatus. The larvae and pupae of Culex quinquefasciatus were exposed to various concentrations (31.25-1000 ppm) of methanolic extract and its fractions for 24 hours of exposure period. For knock-down bioassay (filter paper impregnation bioassay) different concentration of the methanolic extract and its various fractions (i.e. 0.0625, 0.125, 0.25, 0.5 and 1mg/mL) were applied for 1 hour exposure period. The results were statistically analysed using standard deviation, probit analysis, and linear regression. The R2 values of larvae, pupae, and adult range from 0.4 to 0.99. The values of LC50 (concentration causing 50% mortality) for late 3rd instar larvae after 24 hours exposure period range from 93-1856.7 ppm, while LC90 values range from 424 -7635.5ppm. The values of LC50for pupae range form 1326.7-6818.4ppm and and values of LC90 range from 3667.3-17427.9ppm, respectively. The KDT50 range from 0.30 to 2.8% and KDT90 values range from1.2 to 110.8%, respectively. In conclusion, Justicia adhatoda may be effective for controlling populations of vector mosquito.

Resumo As neoplasias hematológicas e de células hematopoiéticas dos genes e as células hematopoiéticas estão associadas à mutação genética, geralmente em nível cromossômico. O estudo citogenético padrão é amplamente aceito como um dos principais determinantes diagnósticos e prognósticos em pacientes. Portanto, o presente estudo descritivo e transversal buscou determinar a análise citogenética de neoplasias hematológicas frequentes no Paquistão. Um total de 202 amostras de medula óssea periférica ou sangue de pacientes com malignidade hematológica benigna e maligna foi coletado usando uma técnica convencional de banda G. Entre os pacientes inscritos, a média de idade foi de 21,5 anos ± 23,4, e a distribuição por gênero mostrou uma marcada predominância da população masculina de 147 (73%) em comparação com a feminina de 55 (27%). Pacientes na faixa etária (2-10 anos) tiveram a maior frequência, 48 (24%), de neoplasias hematológicas, seguida da idade (11-20 anos) com 40 (20%). Cariótipos normais (46, XX / 46, XY) foram encontrados em 51% (n = 103) dos pacientes. Além disso, a frequência de cariótipo complexo foi de 30 (15%), enquanto normal foi observada em 171 (85%) pacientes. Leucemia linfoblástica aguda pré-B (LLA Pré-B) foi a doença maligna mais prevalente de 66 (33%), seguida por leucemia mieloide crônica (LMC) de 41 (20%) e leucemia linfocítica aguda de 29 (14%). A translocação foi o 50 mais prevalente (25%), seguido por hipotriploidia 14 (7%) e monossomia 8 (4%) na análise de aberração cromossômica. Além disso, a translocação t (9:22) encontrada foi de 20 (10%) na LMC, com a maioria na faixa etária (31-40 anos). Este estudo recomenda que o cariótipo deve ser testado com frequência em condições hematológicas porque pode fornecer informações sobre as alterações cromossômicas relativas associadas a doenças malignas específicas.

Abstract Hematological and hematopoietic cells malignancies of the genes and hematopoietic cells are associated with the genetic mutation, often at the chromosomal level. The standard cytogenetic study is widely accepted as one of the main diagnostics and prognostic determinants in patients. Therefore, the current descriptive and cross-sectional study sought to determine the cytogenetic analysis of frequent hematological malignancies in Pakistan. A total of 202 peripheral bone marrow or blood samples from patients with benign and malignant hematological malignancy were taken using a conventional G-banding technique. Among enrolled patients, the mean age was 21.5 years ± 23.4, and gender-wise distribution showed a marked predominance of the male 147 (73%) population compared to the female 55 (27%). Patients in the age group (2-10 years) had the highest frequency, 48 (24%), of hematological neoplasms, followed by age (11-20 years) with 40 (20%). Normal karyotypes (46, XX/46, XY) was found in 51% (n=103) patients. Furthermore, the frequency of complex karyotype was 30 (15%), while normal was seen in 171 (85%) patients. Pre-B Acute Lymphoblastic Leukemia (Pre-B ALL) was the most prevalent malignancy of 66 (33%), followed by Chronic Myelogenous Leukemia (CML) of 41 (20%) and Acute Lymphocytic Leukemia of 29 (14%). Translocation was the most prevalent 50 (25%), followed by hypotriploidy 14 (7%) and monosomy 8 (4%) on chromosome aberration analysis. In addition, t(9:22) translocation was found to be 20 (10%) in CML, with the majority in the age group (31-40 years). This study recommends that karyotyping should be tested frequently in hematological conditions because it may provide insight into the relative chromosomal changes associated with particular malignancies.

Abstract Bacillus cereus is considered the most potent bacterial strain in terms of the increment in induced proteins during thermal treatment at 52 °C for 90 min. Protein production in food-born microorganism (Bacillus cereus) recovered from contaminated food was investigated in response to heat shock treatment. Bacterial tolerance towards pH, salinity, and temperature at various levels was also investigated. Heat-shock proteins (HSPs) produced when exposed to 52 °C for up to 60 minutes led to significant differences (30%) above the untreated control (37 °C), and the maximum difference was recorded at 52°C at 90 minutes. ISSR detected a higher number of bands/primer than RAPD (13.7 vs. 12.7, respectively), and more polymorphic bands (10.7 vs. 8.4 bands/primer, respectively). The untreated bacterial strain did not grow at pH levels lower than 3, whereas the thermally treated strain grew significantly at pH two. A consistent increase in HSPs was observed, with a gradual increase in salinity of less than 16%. Surprisingly, the gradual increase in temperature did not induce tolerance against higher temperatures. However, a significant growth rate was noticed in response to heat-shocked treatments. The untreated Bacillus cereus demonstrated antibiotic resistance to gentamycin and clindamycin (1.54 and 1.65 cm, respectively), much lower than the corresponding inhibition areas with preheat-treated test pathogen which were recorded (2.37 and 2.49 cm, respectively).

Resumo Bacillus cereus é considerada a cepa bacteriana mais potente em termos de incremento de proteínas induzidas durante o tratamento térmico a 52 °C por 90 min. A produção de proteínas em microorganismos de origem alimentar (Bacillus cereus) recuperados de alimentos contaminados foi investigada em resposta ao tratamento de choque térmico. A tolerância bacteriana ao pH, salinidade e temperatura em vários níveis também foram investigadas. Proteínas de choque térmico (HSPs) produzidas quando expostas a 52 °C por até 60 minutos levaram a diferenças significativas (30%) acima do controle não tratado (37 °C), e a diferença máxima foi registrada a 52 °C em 90 minutos . O ISSR detectou um maior número de bandas/iniciador do que o RAPD (13,7 vs. 12,7, respectivamente) e mais bandas polimórficas (10,7 vs. 8,4 bandas/iniciador, respectivamente). A cepa bacteriana não tratada não cresceu em níveis de pH abaixo de 3, enquanto a cepa tratada termicamente cresceu significativamente em pH dois. Observou-se aumento consistente de HSPs, com aumento gradual da salinidade inferior a 16%. Surpreendentemente, o aumento gradual da temperatura não induziu tolerância a temperaturas mais altas. No entanto, uma taxa de crescimento significativa foi observada em resposta aos tratamentos de choque térmico. O Bacillus cereus não tratado demonstrou resistência antibiótica à gentamicina e clindamicina (1,54 e 1,65 cm, respectivamente), muito menor do que as áreas de inibição correspondentes com patógeno de teste pré-tratado que foram registradas (2,37 e 2,49 cm, respectivamente).

BACKGROUND: Despite the important role of social enterprises in addressing the gaps in social service and infrastructure provision by national governments, the organisational capabilities that make social enterprises competitive and effective are still under-researched in emerging economies. AIM: The purpose of the study is to extend the extant studies on the nexus between organisational ambidexterity and firm performance to the social enterprise context. More specifically, we draw on the Dynamic Capability Theory to investigate business-like social enterprises in Ghana and how organisational ambidexterity (i.e. exploitation and exploration) influences their social and economic performance. SETTING: Organisational ambidexterity was tested on 317 randomly selected social enterprises in Ghana. METHOD: The study employed a quantitative research design via a survey questionnaire while the structural equation modelling technique in Analysis of a Moment Structure (AMOS) software was used to test the study's hypotheses RESULTS: It was found, among other things, that both exploration and exploitation are positively and significantly related to social performance (social marketing achievement and social value creation) and economic performance (commercial marketing achievement and economic value creation) of social enterprises. That is, the simultaneous pursuit of exploitative and explorative initiatives does not decrease but increase social enterprise performance. These results defy the conventional wisdom that the trade-off between exploitative and explorative functions may decrease organisation efficiency and bring unnecessary costs. CONCLUSION: Organisational ambidexterity can be considered a cradle of strategic revitalisation and competitive advantage for social enterprises enhancing social and economic performance. Therefore, we suggest that social entrepreneurs should pursue exploitative and explorative ambidexterity simultaneously through appropriate structural ambidexterous mechanisms like structural separations or contextual ambidexterous mechanisms such as non-structural separations of units.

Resumo No presente estudo, investigou-se a composição bioquímica de algumas espécies Echinodermata (Holothuroidea, Echinoidea) do Mar Vermelho no Egito. Os resultados mostraram que a maior porcentagem de ácidos graxos saturados (SFA) foi na espécie Holothuria nobilis e a menor porcentagem foi registrada em Holothuria scabra. A maior porcentagem de ácidos graxos monoinsaturados (MUFA) foi registrada na espécie Pearsonothuria graeffei, enquanto a menor porcentagem foi registrada em Holothuria atra. O maior percentual de ácidos graxos poli-insaturados (PUFA) foi registrado em Holothuria nobilis e o menor percentual foi registrado em Holothuria atra. A maior porcentagem de ácidos graxos ômega-3 foi registrada na espécie Stichopus hermanni, entretanto, a menor porcentagem foi registrada em Diadema setosum. A maior porcentagem de ácidos graxos ômega-6 foi registrada em Bohadschia vitiensis e a menor porcentagem foi registrada em Holothuria atra. Além disso, o nível de aminoácido não-essencial (NEAA) glicina foi o mais alto em todas as espécies e o de serina foi o mais baixo, enquanto o nível de aminoácido essencial (EAA) arginina foi o mais alto e a cisteína foi o mais baixo. Todos os NEAA registraram concentrações mais altas em S. hermanni, exceto prolina. Os aminoácidos essenciais registrados foram histidina, isoleucina, fenilalanina e leucina. A leucina apresentou alto nível na espécie Pearsonothuria graeffei. Tirosina, valina, treonina e arginina apresentaram níveis elevados em Stichopus hermanni. Assim, o presente estudo comprovou que o pepino-do-mar possui grande valor nutricional.

All of the NEAA recorded highest concentrations in S. hermanni except proline. The recorded essential amino acids were histidine, isoleucine, phenylalanine, and leucine. The latter was high in Pearsonothuria graeffei. Tyrosine, valine, threonine, and arginine were high in Stichopus hermanni. The present study proved that sea cucumbers has great nutritional value.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a novel sickness that emerged worldwide as an unprecedented crisis and led to major effects on the daily life of the general public as well as negative impacts on their mental well-beingAIM: This study aimed to assess satisfaction with life and psychological distress during the COVID-19 pandemic in EgyptSETTING: An online study was conducted in EgyptMETHODS: A cross-sectional online survey was fulfilled by 1056 Egyptian adults from 06 to 13 June 2020. Psychological distress and satisfaction with life were measured by Arabic validated versions of the Kessler Psychological Distress Scale (K10) and the Satisfaction with Life Scale (SWLSRESULTS: About half of the surveyed respondents (51%) were satisfied with their life, whilst 57.4% experienced severe psychological distress. The independent predictors of satisfaction with life are being married, satisfactory income, low distress, moderate distress and high distress (adjusted odds ratio [AOR] = 1.2, 3.0, 2.5, 6.9, 5.2 and 2.1, respectively). Being a female, having secondary education, > secondary education, unsatisfactory income and presence of mental illness are the independent predictors of mental distress (AOR = 2.3, 3.9, 1.9, 1.9, 1.6 and 4.0, respectivelyCONCLUSION: The study provides evidence about the high prevalence of psychological distress during the peak period of Egypt's COVID-19 pandemic. The study results highlight the enhancement of development interventions to promote psychological well-being and feeling of satisfaction with life during the pandemic

Dapoxetine is a selective serotonin reuptake inhibitor, used to treat premature ejaculation in men. Dapoxetine may interact with the DNA and hence this study investigated dapoxetine and calf thymus DNA (ctDNA) binding interaction. The interaction study of ligands to DNA is of importance in the development of molecular probes and therapeutic agents. Spectroscopic techniques including spectrofluorometry and spectrophotometry were employed to study this interaction. Fluorescence studies indicated a static quenching mechanism between dapoxetine and ctDNA. Groove binding was suggested as the mode of interaction between dapoxetine and ctDNA based on UV absorption, circular dichroism (CD) spectroscopy, iodide quenching and molecular docking studies. The studies conducted at three different temperatures 298,303 and 310 K indicated a strong binding interaction at higher temperatures. Thermodynamic studies conducted indicated involvement of hydrophobic interaction between ctDNA and dapoxetine and were entropy-driven. Ethidium bromide probe study suggested that dapoxetine does not bind to ctDNA in an intercalative fashion. Iodide quenching studies further proved the non-intercalative binding of ctDNA with dapoxetine. Ionic strength studies conducted ruled out the electrostatic binding mechanism between ctDNA and dapoxetine. Molecular docking analysis performed for the dapoxetine with calf thymus DNA (ctDNA) interaction and confirmed minor groove binding of dapoxetine to ctDNA. The study helped to reveal the binding interaction mechanism between dapoxetine and ctDNA.

ABSTRACT The hepatoprotective activities of two traditionally used plants, Cleome droserifolia (Forssk.) Delile, Cleomaceae, and Artemisia annua L., Asteraceae, were recently reported. However, the biologically active metabolites responsible for this activity were not identified. The aqueous extract of C. droserifolia aerial parts, and the polar fraction of A. annua leaves were screened for their antioxidant activities using the 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulphonic acid) assay. The in vitro viability of HepG-2 cells treated with CCl4 and the extracts were assessed by MTT assay. The effects of the extracts on the liver enzymes and the total soluble protein in CCl4-intoxicated HepG-2 cells were investigated. An HPLC/PDA/ESI/MS–MS based analysis was carried out for extract of C. droserifolia and polar fraction of A. annua. Both exhibited pronounced free radical scavenging activities (86 and 83%, respectively). Both showed a significant increase in cell viability: 86.43% for the extract of C. droserifolia and 79.32% for polar fraction of A. annua. Only the extract of C. droserifolia (39.6 ± 5.41 and 20.4 ± 6.91 IU/dl, respectively) and polar fraction of A. annua (40.8 ± 2.14 and 24.5 ± 3.11 IU/dl, respectively) restored the levels of liver enzymes (aspartate transaminase and alanine transaminase, respectively) compared to the CCl4 intoxicated group (87.5 ± 4.34 and 34.1 ± 8.12 IU/dl, respectively) and other herbal extracts. More than fifty phenolic secondary metabolites were identified in the extracts under investigation. The significant hepatoprotective activities of both extracts seemed to be strongly connected to their content of hydroxycinnamoyl quinic acids and flavonoids.

ABSTRACT The objective of this study was to evaluate the effect of source of roughage and crude protein level on feeding performance and carcass traits of Majaheem camels (Camelus dromedarius). Forty-eight male calf-camels weighing 203.3±5.1 kg were equally assigned to a 2 × 3 factorial arrangement of two sources of roughage (Rhodes grass hay and dry salicornia biomass) and three dietary crude protein levels (12, 14.5, and 17%); the feeding trial lasted for 18 weeks. The results showed that slaughter and hot carcass weights, average daily gain, dry matter intake, feed efficiency, and separable fat from 9th-11th rib joint increased as the crude protein in the diets increased from 12 to 14.5%, whereas increasing crude protein to 17% resulted in no further changes. Slaughter weight, average daily gain, hot carcass weight, rib eye area, and separable lean did not differ between Rhodes grass and salicornia diets, but salicornia-fed camels had higher dry matter intake and produced heavier kidney fat and separable fat weights than camels fed Rhodes grass diets. It is suggested that the inclusion of salicornia biomass as a roughage ingredient up to 25% in the diet containing not greater than 14.5% crude protein can be utilized without adverse effect on feeding performance of calf-camels.
