05). Moreover, the TGF-β expression in the LG and HG groups were significantly or highly significantly lower (P less then 0.05 or P less then 0.01) than those of I group from 2 dpi to 5 dpi. In addition, ghrelin administration downregulated MMP-9 expression evoked by IBDV from 2 dpi to 7 dpi (P less then 0.05 or P less then 0.01). These results suggested that ghrelin attenuated the bursal fibrosis degree of IBDV-infected SPF chicks by reducing the number of inflammatory cells and by decreasing the expression of TGF-β and MMP-9, which shortened the process of bursa recovery.The ability of immune defense and resistance to physiological stress is crucial to animal health and survival. This study investigated the regulation of γ-aminobutyric acid (GABA) on metabolic homeostasis and its enhancement of hepatopancreas health in juvenile Chinese mitten crab (Eriocheir sinensis) under food deprivation. Juvenile crabs of 400 individuals were divided into four treatment groups a control group without injection, and injections with a phosphate-buffered saline solution, 100 μmol GABA/mL and 1000 μmol GABA/mL, respectively. Hypoglycemia was induced by fasting, whereas the GABA treatment regulated hemolymph glucose homeostasis. The quantitative real-time PCR (qRT-PCR) results showed that the GABA treatment significantly up-regulated the mRNA expression levels of crustacean hyperglycemic hormone (CHH) and pyruvate kinase (PK). In contrast, the expression of E. sinensis insulin-like peptide (EsILP) was significantly down-regulated in the cranial ganglia, thoracic ganglia and hepatopancreas. Moreover, acid phosphatase (ACP), alkaline phosphatase (AKP), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities were significantly increased in the hepatopancreas by the GABA treatment. Furthermore, the hemocyanin content in serum was significantly increased with the GABA injection, and the glutathione (GSH) content, total superoxide dismutase (T-SOD) activity and catalase (CAT) activity in the hepatopancreas showed a similar increasing trend with the dose elevation of GABA. Therefore, these results indicate that GABA can effectively maintain the hemolymph glucose homeostasis by regulating the levels of glucose metabolism-related hormones and key enzymes to promote the degradation and utilization of hepatopancreas glycogen. Meanwhile, GABA can improve the hepatopancreas function and immune status of juvenile E. sinensis under fasting stress. The treatment with GABA may provide a clue to guide health management in crab farming.Anthropogenic activity is a major driver of seabird injury and mortality in the 21st century. Although most seabirds perish within the natural environment as a result of human activities, some are rescued and admitted to rehabilitation centres. Despite the considerable number of admissions, little is known regarding the physiological response seabirds have to specific admission reasons and the rehabilitation process. In this study, we aimed to determine the effect of injury, emaciation, oiling, individual removal from the natural environment and the rehabilitation process on the physiological stress response of the African penguin (Spheniscus demersus). Urofaecal samples were collected from African penguins throughout a three-stage rehabilitation process and quantified for glucocorticoid metabolites (ufGCM). The three stages included an initial ICU crate stage (Stage 1), an ICU pen stage (Stage 2) and a rehabilitation stage (Stage 3). Data were analysed using a generalised linear model in order to determine the effect of admission reason, age and rehabilitation stage (Stage 1, 2 and 3) on ufGCM levels. Although the model indicated that only Stage 1 was a significant driver of adrenocortical activity in the study population, ufGCM levels of injured and emaciated animals within Stage 1 were considerably higher than those of birds with any other admission reason across all stages. This is the first study examining the causes and effect of rehabilitation on the physiological stress response in African penguins. Enhanced care and attention should be given to rescued individuals, especially during the first stage of rehabilitation, to reduce perception of additional stressors and thus increase the chance of full recovery.

To evaluate oncological outcomes and treatment-related toxicities of elderly salivary gland cancer patients undergoing (chemo)radiotherapy.

Local/locoregional control (LRC), progression-free survival (PFS) and overall survival (OS) of elderly patients≥65years with primary salivary gland cancers undergoing (chemo)radiotherapy between 2005 and 2020 at three tertiary cancer centers were calculated. The impact of clinicopathological and treatment parameters on outcomes were analyzed, and acute and chronic toxicities were quantified.

288 elderly salivary gland cancer patients were included in this multicenter analysis, and their median LRC, PFS and OS amounted to 113, 39 and 75months, respectively. Age, performance status, comorbidities, definitive vs. adjuvant (chemo)radiotherapy as well as locally/locoregionally advanced cancers and distant metastases correlated with reduced outcomes in elderly salivary gland patients. Patients receiving dose-escalated radiotherapy (total doses>70 Gy

) with carbon ion formance rather than chronological patient age.Benign prostatic hyperplasia (BPH) is an age-related disease in men. Mesenchymal /stromal and epithelial cells interactions are essential to prostate functions. In this study, human nonmalignant prostate epithelial RWPE-1 cells were cocultured with testosterone (TE) -exposed prostate stromal fibroblasts WPMY-1 cells (TE-WPMY-1). The survival rate, epithelial-mesenchymal transition (EMT) and collagen deposition of RWPE-1 were observed. Selleckchem Hydroxychloroquine The expression profiles of circRNAs, lncRNAs and mRNAs in WPMY-1-derived exosome-like vesicles (WPMY-1-exo) were explored by high-throughput RNA sequencing. Firstly, both TE-WPMY-1 and TE-WPMY-1-exo significantly promoted RWPE-1 cells proliferation. Secondly, 41 circRNAs, 132 lncRNAs and 1057 mRNAs were differentially expressed (DE) between TE-WPMY-1-exo and the control. Functional enrichment analyses, co-expression analyses and quantitative real-time PCR verification showed that the DE RNAs played important roles in cell proliferation, structure, phenotype and fibrosis. Lastly, blocking WPMY-1-exo biogenesis/release by GW4869 can attenuate TE-WPMY-1-stimulated RWPE-1 cells EMT and collagen deposition.
