ABSTRACT This study investigated the effects of bamboo vinegar (BV) on production performance, egg quality, antioxidant status, and serum biochemical parameters of laying hens during summer. One hundred twenty 36-week-old Hy-Line Brown laying hens were randomly assigned to 4 groups, with 30 hens per group. The control group was fed a basal diet and 1 mL/kg, 5 mL/kg, and 10 mL/kg BV were added to the basal diet of the 0.1% BV, 0.5% BV and 1.0% BV groups, respectively. The experiment lasted 30 days and showed that the production performance was not significantly affected by the addition of BV (p>0.05). Egg shape index and glutathione peroxidase activity in serum in BV-supplemented groups were significantly increased (p<0.05). The total protein and the albumin content in the 0.1% BV, 0.5% BV, and 1.0% BV groups were significantly increased compared to the control group (p<0.05). These results suggested that dietary BV could improve the antioxidant capacity and the egg shape index of laying hens in summer.

ABSTRACT Gut microbiota plays an important role in animal health, production and diseases. Little is known about whether heat stress alters the composition of quail gut microbiota; therefore, we studied the effects of heat stress on growth performance, antioxidant functions, heat shock proteins and caecal microbiota. Two groups of 40 (20-day-old) quails were set up, including a control reared at 24 ± 2°C and a heat stress group subjected to heat stress at 36 ± 2°C for 4 h per day for 7 consecutive days. We found that heat stress significantly elevated the relative expression levels of HSP70 and HSP90 mRNA in the thymus, bursa and spleen by real-time fluorescence quantitative PCR assay, indicating successful establishment of the experimental model. Heat stress was found to have an effect on gut microbiota composition. At the genus level, Alistipes were significantly increased in the heat stress group. PICRUSt2 function prediction revealed that most of the KEGG pathways with high temperature-induced abundance differences are metabolism-related. These data indicated that heat stress reduced the production performance of quails by affecting antioxidant functions, as well as the composition and structure of the intestinal microbiota. The results of this study provide technical information for conducting research on heat stress prevention and control techniques in quails. health diseases therefore functions 20dayold dayold 20 old (20-day-old up 2 2C C 3 days HSP HSP7 HSP9 thymus realtime real time assay model level PICRUSt temperatureinduced temperature induced metabolismrelated. metabolismrelated metabolism related. related metabolism-related

RESUMO Porcos tibetanos são caracterizados por diferenças fenotípicas significativas em relação aos porcos de planície. Nosso estudo anterior demonstrou que os genes CRYAB e CTGF eram expressos diferentemente nos tecidos do coração entre os porcos tibetanos (raça das terras altas) e Yorkshire (raça das terras baixas), indicando que eles poderiam participar da adaptação à hipoxia. CRYAB (ɑB-crystallin) e CTGF (fator de crescimento do tecido conjuntivo) também foram relatados como estando associados ao desenvolvimento pulmonar. Entretanto, os padrões de expressão do CRYAB e CTGF nos tecidos pulmonares em diferentes altitudes e sua caracterização genética não são bem compreendidos. Neste estudo, o qRT-PCR e a mancha ocidental de tecido pulmonar revelou níveis de expressão de CRYAB mais elevados em porcos tibetanos e Yorkshire de altitude e média altitude do que em seus pares de planície. Com um aumento na altitude, o nível de expressão do CTGF aumentou nos porcos tibetanos, enquanto diminuiu nos porcos Yorkshire. Além disso, foram identificados dois novos polimorfismos de um único nucleotídeo na região flanqueadora de CRYAB (g.39644482C>T e g.39644132T>C) e CTGF (g.31671748A>G e g.31671773T>G). O polimorfismo pode contribuir parcialmente com as diferenças nos níveis de expressão entre grupos a uma mesma altitude. Estas descobertas proporcionam novos conhecimentos sobre as adaptações de hipoxia a alta altitude dos porcos tibetanos.

ABSTRACT Tibetan pigs are characterized by significant phenotypic differences relative to lowland pigs. Our previous study demonstrated that the genes CRYAB and CTGF were differentially expressed in heart tissues between Tibetan (highland breed) and Yorkshire (lowland breed) pigs, indicating that they might participate in hypoxia adaptation. CRYAB (ɑB-crystallin) and CTGF (connective tissue growth factor) have also been reported to be associated with lung development. However, the expression patterns of CRYAB and CTGF in lung tissues at different altitudes and their genetic characterization are not well understood. In this study, qRT-PCR and western blot of lung tissue revealed higher CRYAB expression levels in highland and middle-highland Tibetan and Yorkshire pigs than in their lowland counterparts. With an increase in altitude, the expression level of CTGF increased in Tibetan pigs, whereas it decreased in Yorkshire pigs. Furthermore, two novel single-nucleotide polymorphism were identified in the 5′ flanking region of CRYAB (g.39644482C>T and g.39644132T>C) and CTGF (g.31671748A>G and g.31671773T>G). The polymorphism may partially contribute to the differences in expression levels between groups at the same altitude. These findings provide novel insights into the high-altitude hypoxia adaptations of Tibetan pigs.

ABSTRACT This study aimed to evaluate the effects of adding Moringa oleifera leaf powder (MOLP) to the basal diets of chickens at late laying period on clutch trait, reproductive organs, serum reproductive hormones and reproduction-related genes expression. A total of 350 hens (37 weeks old) with similar laying rate and clutch trait were randomly allocated into five groups, and fed 0 (Control, CON), 2.5 (MOLP2.5), 5, 7.5 and 10% MOLP supplemented diets for 6 weeks. The hens supplemented with 2.5% MLOP had the average clutch length, clutches and clutch intensity close to those in CON. The numbers and weight of hierarchal follicle were significantly increased at the supplementation 2.5% MOLP group. The estrogen concentration was highest in MOLP2.5 group and lowest in MOLP10 group. Expression levels of steroidogenesis-related genes of StAR and Cyp19a1 were higher in MOLP2.5, MOLP5 and MOLP7.5 groups compared with that in the control. These findings suggested that dietary supplementation with 2.5% MOLP effectively increased hierarchal follicle numbers, estrogen level and gene expression of StAR and Cyp19a1, which has a potential beneficial effect on laying performance in laying chicken.

ABSTRACT In order to find out the main factors influenced the hatchability and improve the hatchability of the windowed chicken eggs at stage X, several experiments were made on the basis of the former patent of eggshell windowing methods on equatorial plane, such as cutting and sealing techniques, air cell recovering, laying position immediately after sealing, as well as the injection volumes into the subgerminal cavity of the blastoderm. The result showed that:1) the best sealing material combination was straw powder (SP) and instant glue (IG); 2) there was a highly positive correlation between air cell rate and hatchability; 3) the highest hatchability increased to 71.6% when the eggs were windowed and sealed with IG dropped firstly and then SP sprinkled, finally lay down with the blunt end upward immediately after being sealed; 4) the hatchability was significantly reduced as injection volume (DMEM) was increased (p<0.05 or p<0.01) from 1 µL to 10 1 µL, and the group of injecting 1 µL was the highest (48.4 %). The hatchability and efficiency with such method of windowing, injecting, and sealing was the highest at the present time (more than 30 eggs per hour per person), and it might be broadly used in the fields of avian transgenesis, genetic resources preservation, and embryonic development model of human medicine.

The aim of this study was to discuss the safety and efficacy of regional citrate anticoagulation (RCA) on continuous blood purification (CBP) during the treatment of multiple organ dysfunction syndrome (MODS). Thirty-five patients with MODS were divided into two groups: the local citrate anticoagulation (RCA) group, and the heparin-free blood purification (hfBP) group. The MODS severity was assessed according to Marshall’s MODS score criteria. Blood coagulation indicators, blood pressure, filter lifespan, filter replacement frequency, anticoagulation indicators, and main metabolic and electrolyte indicators were analyzed and compared between RCA and hfBP groups. RCA resulted in lower blood pressure than hfBP. The filter efficacy in RCA treatment was longer than in the hfBP group. The blood clearance of creatine, blood urea nitrogen and uric acid was better in the RCA group. RCA also led to higher pH than hfBP. Neither treatment resulted in severe bleeding events. In addition, MODS score was positively correlated with prothrombin time and activated partial thromboplastin time but negatively correlated with platelet concentration. RCA is a safer and more effective method in CBP treatment; however, it could also lead to low blood pressure and blood alkalosis.

ABSTRACT Background: In Taiwan, persons over 65 years old have higher prevalence of hepatitis C. Among these patients, around 50% have non-alcoholic fatty liver disease (NAFLD). Since cardiovascular diseases and diabetes are main causes of death in this age group, in this cross-sectional study, we tried to evaluate the effects of NAFLD and hepatitis C on the risk of metabolic syndrome (MetS). Methods: In total, 25 116 subjects over 65 years old who presented for routine health check-ups were enrolled. From the results of seropositivity for hepatitis C and abnormal echogenicity, they were classified into four groups: normal (N), subjects with only hepatitis C (C), subjects with only abnormal echogeni-city (E) and subjects with both hepatitis C and abnormal echogenicity (CE). Results: Subjects in both groups E and CE had higher abnormal MetS components than group C. Among all five components, triglyceride (TG) was the one having the highest odds ratio (OR) in determining the incidence of MetS in groups C and E. Finally, compared to group N, both groups E and CE had significantly higher OR for having MetS. However, after adjusting for confounding factors, only the significance between groups E and N remained. In other words, higher MetS was noted in group E compared to group N and there was no difference in incidence of MetS between group CE and group N. Conclusions: Chronic hepatitis C is a protective factor against having MetS and this effect might be due to lower TG level in the elderly. Further studies are warranted for the underlying mechanisms.

RESUMEN Antecedentes: En Taiwán, las personas mayores de 65 años tienen mayor prevalencia de hepatitis C. De estos pacientes, aproximadamente el 50% padece la enfermedad del hígado graso no alcohólico (HGNA). Puesto que la diabetes y las enfermedades cardiovasculares son la principal causa de muerte en este grupo etario, en este estudio transversal tratamos de evaluar los efectos de la EHGNA y la hepatitis C sobre el riesgo de síndrome metabólico (SMet). Métodos En total, se inscribieron 25116 sujetos mayores de 65 años que se presentaron para hacerse chequeos de salud rutinarios. A partir de los resultados de seropositividad para la hepatitis C y la ecogenicidad anormal, estos fueron clasificados en cuatro grupos: sujetos normales (N), sujetos sólo con hepatitis C (C), sujetos sólo con ecogenicidad anormal (E), y sujetos con hepatitis C y ecogenicidad anormal (CE). Resultados: Los sujetos en los grupos E y CE tuvieron componentes de SMet anormales más altos que los del grupo C. De los cinco componentes, el triglicérido (TG) fue el que tuvo el cociente de probabilidades (OR) más alto a la hora de determinar la incidencia de SMet en los grupos C y E. Finalmente, en comparación con el grupo N, tanto el grupo E como el CE tuvieron OR significativamente mayores por poseer SMet. Sin embargo, después del ajuste de los factores de confusión, solamente permaneció la significación entre los grupos E y N. En otras palabras, se observaron SMet más altos en el grupo E en comparación con el grupo N, y no hubo diferencias de incidencia entre el grupo CE y el grupo N. Conclusiones: La hepatitis C crónica es un factor protector frente al SMet, y este efecto podría deberse al bajo nivel de TG en los ancianos. Se requieren otros estudios en relación con los mecanismos subyacentes.

Abstract Our study investigates the influence of sintering temperature on the microstructure (grain size distribution, grain boundary length), electrical conductivity, and oxygen permeation properties of permeation membranes. For this purpose, SrSc0.1Co0.9O3-δ samples with different microstructures were prepared by varying the sintering temperature from 1100 to 1250 ˚C. The average grain sizes were gradually increased, thus the grain boundary lengths decreased with increased sintering temperatures. The influence of the ceramic microstructure on total electrical conductivity was found to be negligible. The oxygen transport properties of the samples were characterized by permeation measurements as a function of temperature in an air/helium oxygen partial pressure gradient. The decrease of the sintering temperature, meaning a decrease of grain size and thus the increase of grain boundary length, leads to an enhanced oxygen permeation flux and a reduced activation energy. This implies that oxygen exchange and transport in the SrSc0.1Co0.9O3-δ membranes occur more rapidly along grain boundaries than in the grain bulk.

ABSTRACT External iliac arterial obstruction is relatively rare in renal transplantation, and may cause surgical failure and ipsilateral leg ischaemia. Prompt diagnosis and management of this kind of complication is essential to rescue the patient and allograft. Four patients with external iliac arterial obstruction caused by Satinsky atrauma forceps in renal transplantation were analysed and summarized. In case one, the obstruction of the external iliac artery distal to the renal allograft caused ipsilateral leg ischaemia. After surgical fixation of the endarterium, the patient recovered from the lower limb ischaemia. In case two, the obstruction of the external iliac artery was located proximal to the renal allograft. Since the endarterial rupture was not found and fixed in time, the renal allograft was lost. The third case was similar to the second. Based on the previous experience, we fixed the endarterium promptly, and transplanted the kidney back successfully. In case four, there was endarterial rupture with atherosclerosis located around the anastomosis stoma. After taking out the atherosclerotic plaque and fixing the endarterium, the blood supply of kidney and lower limb was good. External iliac arterial rupture and obstruction caused by Satinsky atrauma forceps in renal transplantation is rare, but may cause severe and depressing outcome. The critical step is to find and fix the impaired endarterium as early as possible.

RESUMEN La obstrucción arterial ilíaca externa es relativamente rara en el trasplante renal, y puede causar fracaso quirúrgico e isquemia ipsilateral de la pierna. Un pronto diagnóstico y tratamiento de este tipo de complicación es esencial para salvar al paciente y el aloinjerto. Los casos de cuatro pacientes con obstrucción arterial ilíaca externa causada por fórceps Satinsky atrauma en el trasplante renal, fueron analizados y resumidos. En el primer caso, la obstrucción de la arteria ilíaca externa distal al aloinjerto renal, causó una isquemia ipsilateral de la pierna. Después de la fijación quirúrgica del endarterio, el paciente se recuperó de la isquemia de la extremidad inferior. En el segundo caso, la obstrucción de la arteria ilíaca externa fue localizada proximal al aloinjerto renal. Como que la ruptura endarterial no fue detectada y corregida a tiempo, se perdió el aloinjerto renal. El tercer caso fue similar al segundo. Basado en la experiencia anterior, fijamos el endarterio rápidamente, y trasplantamos el riñón de nuevo con éxito. En el cuarto caso, hubo una ruptura endarterial con ateroesclerosis situada alrededor del estoma de la anastomosis. Después de sacar la placa aterosclerótica y fijar el endarterio, el suministro de sangre del riñón y del miembro inferior fue bueno. La ruptura arterial ilíaca externa y la obstrucción causada por fórceps Satinsky atrauma en el trasplante renal ocurren raramente, pero pueden traer consigo un resultado severo y deprimente. El paso fundamental es encontrar y fijar el endarterio dañado lo antes posible.

At present, the identifying of rice nitrogen stress by the chemical analysis is time-consuming and laborious. Machine vision technology can be used to non-destructively and rapidly identify rice nitrogen status, but image acquisition via digital camera is vulnerable to external conditions, and the images are of poor quality. In this research static scanning technology was used to collect images of the rice's top-three leaves that were fully expand in 4 growth periods. From those images, 14 spectral and shape characteristic parameters were extracted by R, G, B mean value function and Regionprops function in MATLAB. After analyzing, the R, G, Leaf Length, LeafArea, and Leaf Perimeter were chosen as 5 universal characteristic parameters for identifying nitrogen stress in 4 growth periods. The results showed that the overall recognition accuracy of nitrogen stress were 92%, 92%, 100% and 96% respectively. Based on the result, the methodology developed in the study is capable of identifying nitrogen stress accurately in the rice.

Ziyuglycoside II is an active compound of Sanguisorba officinalis L. that has anti-inflammation, antioxidation, antibiosis, and homeostasis properties. We report here on the anticancer effect of ziyuglycoside II on human gastric carcinoma BGC-823 cells. We investigated the effects of ziyuglycoside II on cell growth, cell cycle, and cell apoptosis of this cell line. Our results revealed that ziyuglycoside II could inhibit the proliferation of BGC-823 cells by inducing apoptosis but not cell cycle arrest, which was associated with regulation of Bax/Bcl-2 expression, and activation of the caspase-3 pathway. Our study is the first to report the antitumor potential of ziyuglycoside II in BGC-823 gastric cancer cells. Ziyuglycoside II may become a potential therapeutic agent against gastric cancer in the future.

Renal synovial sarcoma is a recently reported neoplasm rarely seen. We report a case of primary renal synovial sarcoma. The signs and symptoms are similar to any primary renal tumour, diagnosis is clinically difficult through general survey or multiple imaging modalities and requires specific molecular and genetic testing. Surgical resection and ifosfamide-based chemotherapy are the mainstay of management. The prognosis can be poor. Physicians should be aware that synovial sarcoma is one of the possibilities of malignancy in the kidney.

El sarcoma sinovial renal es un neoplasma recientemente reportado raramente visto. Reportamos un caso de sarcoma sinovial renal primario. Los signos y síntomas son similares a los que se presentan en el caso de cualquier tumor renal primario. El diagnóstico es clínicamente difícil a través de un estudio general o las modalidades múltiples de la toma de imágenes, y requiere pruebas moleculares y genéticas específicas. La resección quirúrgica y la quimioterapia a base de ifosfamida constituyen el soporte principal de tratamiento. La prognosis puede ser pobre. Los médicos deben ser conscientes de que el sarcoma sinovial es una de las posibilidades de malignidad en el riñón.

Myocardial ischemic preconditioning up-regulated protein 1 (Mipu1), a novel zinc finger protein, was originally cloned using bioinformatic analysis and 5' RACE technology of rat heart after a transient myocardial ischemia/reperfusion procedure in our laboratory. In order to investigate the functions of Mipu1, the recombinant prokaryotic expression vector pQE31-Mipu1 was constructed and transformed into Escherichia coli M15(pREP4), and Mipu1-6His fusion protein was expressed and purified. The identity of the purified protein was confirmed by mass spectrometry. The molecular mass of the Mipu1 protein was 70.03779 kDa. The fusion protein was intracutaneously injected to immunize New Zealand rabbits to produce a polyclonal antibody. The antibody titer was approximately 1:16,000. The antibody was tested by Western blotting for specificity and sensitivity. Using the antibody, it was found that Mipu1 was highly expressed in the heart and brain of rats and was localized in the nucleus of H9c2 myogenic cells. The present study lays the foundation for further study of the biological functions of Mipu1.
