Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.

[Q]: Sigma-1 receptors are involved in the pathophysiological process of several neuropsychiatric diseases such as epilepsy, depression. Allosteric modulation represents an important mechanism for receptor functional regulation. In this study, we examined antidepressant activity of the latest identified novel and selective allosteric modulator of sigma-1 receptor 3-methyl-phenyl-2, 3, 4, 5-tetrahydro-1H-benzo[d]azepin-7-ol (SOMCL-668).', 'A single administration of SOMCL-668 decreased the immobility time in the forced swimming test (FST) and tailing suspended test in mice, which were abolished by pretreatment of sigma-1 receptor antagonist BD1047. In the chronic unpredicted mild stress (CUMS) model, chronic application of SOMCL-668 rapidly ameliorated anhedonia-like behavior (within a week), accompanying with the enhanced expression of brain-derived neurotrophic factor (BDNF) and phosphorylation of glycogen synthase kinase 3 (GSK3) (Ser-9) in the hippocampus. SOMCL-668 also rapidly promoted the phosphorylation of GSK3 (Ser-9) in an allosteric manner in vitro. In the cultured primary neurons, SOMCL-668 enhanced the sigma-1 receptor agonist-induced neurite outgrowth and the secretion of BDNF.

[Q]: To examine the effect of TRIB3 on endoplasmic reticulum stress induced -cell apoptosis and to investigate the mechanism with a specific emphasis on the role of NF-B pathway.', 'We investigated the effect of TRIB3 on ER stress-induced -cell apoptosis in INS-1 cells and primary rodent islets. The potential role of TRIB3 in ER stress inducer thapsigargin (Tg)-induced -cell apoptosis was assessed using overexpression and siRNA knockdown approaches. Inducible TRIB3 -cells, regulated by the tet-on system, were used for sub-renal capsule transplantation in streptozotocin (STZ)-diabetic mice, to study the effect of TRIB3 on ER stress-induced -cell apoptosis in vivo. Apoptosis was determined by TUNEL staining both in vivo and in vitro, while the molecular mechanisms of NF-B activation were investigated.', 'TRIB3 was induced in ER-stressed INS-1 cells and rodent islets, and its overexpression was accompanied by increased -cell apoptosis. Specifically, TRIB3 overexpression enhanced Tg-induced INS-1 derived -cell apoptosis both in vitro and in sub-renal capsular transplantation animal model. Additionally, knockdown of Trib3 blocked Tg-induced apoptosis. Mechanistically, the induction of TRIB3 during ER stress resulted in the activation of NF-B and aggravated INS-1 derived -cell apoptosis, while inhibiting the NF-B pathway significantly abrogated this response and prevented -cell apoptosis, both in vitro and in sub-renal capsular transplantation animal model.

[Q]: We assessed the clinical effectiveness of postoperative enteral stimulation by gut feeding in patients with severe acute pancreatitis (SAP).', 'Medical records of 63 patients who were operated on within the past 4 y due to deterioration of SAP were included in this retrospective study. Patients were stratified in gut feeding (GF; n = 33) and standard therapy (ST; n = 30) groups according to the postoperative therapy provided. The GF group received postoperative standard therapy and enteral stimulation by gut feeding, and the ST group received standard therapy only. The Acute Physiology and Chronic Health Evaluation II score, incidence of the systemic inflammatory response syndrome (SIRS), multiple organ dysfunction syndrome (MODS), daily calories supply, complication rate, and outcomes were analyzed.', 'Patient characteristics did not differ between groups when considering age and severity of the disease. All patients underwent similar surgical interventions. SIRS and MODS were observed initially with the same frequency in both groups. Regression of MODS and a lower postoperative complication rate was observed more often in the GF group. Development of early pulmonary complications was observed in 12.1% to 13.3% in both groups, irrespective of the time of surgery. Subsequently, pulmonary complications developed in 15.2% of GF patients compared with 43.3% of ST patients (P <0.05). Acute renal insufficiency developed similarly in 33.3% of the GF patients and in 26.7% of the ST patients within 3 d after admission. Acute renal insufficiency developed later on only in the ST group (26.7%, P <0.05). Wound- and catheter-related septic complications were considerably more frequent in the ST group (30.0%) than in the GF group (9.1%, P <0.05). Intensive care and hospital stays did not differ. Postoperative gut feeding was associated with 6.1% mortality in the GF compared with 26.7% in the ST (P <0.05).
