Research Progress on Patients of Esophageal Cancer Complicated with Sarcopenia.

The application of immunochemotherapy has significantly enhanced the quality of life and overall survival of patients with esophageal cancer. Sarcopenia, which is increasingly prevalent in these patients, markedly affects prognosis, but can be reversed by appropriate and effective treatment. The narrative review was conducted on PubMed using the keywords ("esophageal" or "esophagus" and "sarcopenia").

Identification of the central role of RNA polymerase mitochondrial for angiogenesis.

Mitochondria are central to endothelial cell activation and angiogenesis, with the RNA polymerase mitochondrial (POLRMT) serving as a key protein in regulating mitochondrial transcription and oxidative phosphorylation. In our study, we examined the impact of POLRMT on angiogenesis and found that its silencing or knockout (KO) in human umbilical vein endothelial cells (HUVECs) and other endothelial cells resulted in robust anti-angiogenic effects, impeding cell proliferation, migration, and capillary tube formation. Depletion of POLRMT led to impaired mitochondrial function, characterized by mitochondrial depolarization, oxidative stress, lipid oxidation, DNA damage, and reduced ATP production, along with significant apoptosis activation.

Estimation of rice yield using multivariate analysis techniques based on meteorological parameters.

This study aims to develop predictive models for rice yield by applying multivariate techniques. It utilizes stepwise multiple regression, discriminant function analysis and logistic regression techniques to forecast crop yield in specific districts of Haryana. The time series data on rice crop have been divided into two and three classes based on crop yield.

Cross-sectional study on dysphagia evaluation in community-dwelling older adults using the Eating Assessment Tool (EAT) -10, EAT-2, and Water Swallow Test.

Background: Dysphagia is a health concern that causes severe complications and affects the life quality of the older population. This study aimed to determine the diagnostic performance of the Eating Assessment Tool (EAT)-2 compared with the EAT-10 and the Water Swallow Test (WST) in screening for dysphagia.

Methods: A cross-sectional study was conducted among 5,090 community-dwelling older adults.

total protein promotes proliferation and secretion of collagen in NIH/3T3 cells by activating extracellular signal-related kinase pathway.

Background: Recently, protein from ginseng was studied and used for the treatment of several kinds of diseases. However, the effect of ginseng total protein (GTP) on proliferation and wound healing in fibroblast cells remains unclear.

Methods: In this study, cell viability was analyzed using the MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay.

Baclofen Protects Primary Rat Retinal Ganglion Cells from Chemical Hypoxia-Induced Apoptosis Through the Akt and PERK Pathways.

Retinal ganglion cells (RGCs) consume large quantities of energy to convert light information into a neuronal signal, which makes them highly susceptible to hypoxic injury. This study aimed to investigate the potential protection by baclofen, a GABA receptor agonist of RGCs against hypoxia-induced apoptosis. Cobalt chloride (CoCl) was applied to mimic hypoxia.

Motivating protégés' personal learning in teams: a multilevel investigation of autonomy support and autonomy orientation.

This study examined the roles of 3 multilevel motivational predictors in protégés' personal learning in teams: an autonomy-supportive team climate, mentors' autonomy support, and protégés' autonomy orientation. The authors followed 305 protégés in 58 teams for 12 weeks and found that all 3 predictors were positively related to the protégés' personal learning in teams and that an autonomy-supportive team climate augmented the effects of mentors' autonomy support and protégés' autonomy orientation on protégés' personal learning in teams. Protégés' personal learning in teams mediated the interactive effects of an autonomy-supportive team climate with mentors' autonomy support or protégés' autonomy orientation on protégés' behavioral and attitudinal outcomes, including their organizational citizenship behaviors and job involvement.

Adiponectin activation of AMPK disrupts leptin-mediated hepatic fibrosis via suppressors of cytokine signaling (SOCS-3).

Adiponectin is an adipocytokine that was recently shown to be anti-fibrogenic in hepatic fibrosis. Leptin, on the other hand, promotes hepatic fibrosis. The purpose of the present study was to elucidate a mechanism (or mechanisms) whereby adiponectin dampens leptin signaling in activated hepatic stellate cells (HSCs), and prevents excess extracellular matrix production.

Enforced expression of MCAM/MUC18 increases in vitro motility and invasiveness and in vivo metastasis of two mouse melanoma K1735 sublines in a syngeneic mouse model.

Human MCAM/MUC18 has been shown to increase metastasis of human melanoma cells in xenograft mouse systems. To be more relevant to understanding the progression of clinical melanoma and for designing better preclinical therapeutic trials, it is highly desirable to establish a syngeneic mouse model for studying the mechanisms of MCAM/MUC18-mediated tumorigenesis and metastasis of melanoma cells. To reach this goal, we transfected the mouse MCAM/MUC18 (moMCAM/MUC18) cDNA into two MCAM/MUC18-minus, low-metastatic mouse melanoma K1735 sublines, K1735-10 (tumor(-)/met(low)) and K1735-3 (tumor(+)/met(low)), and selected for G418-resistant clones, which expressed different levels of moMCAM/MUC18, and used for testing the effect of MCAM/MUC18 overexpression on their in vitro growth rate, motility, and invasiveness and in vivo subcutaneous tumor growth and pulmonary metastasis in syngeneic mice.

Increased expression of MUC18 correlates with the metastatic progression of mouse prostate adenocarcinoma in the TRAMP model.

Purpose: The transgenic adenocarcinoma mouse prostate (TRAMP) model is a paradigm that closely mimics the progression of clinical prostate cancer. We have previously reported that MUC18, a cell adhesion molecule in the Ig gene superfamily, is a marker as well as an important mediator for the metastatic potential of human prostate cancer cells. In this study we investigated the possible correlation of increased MUC18 expression with the malignant progression of prostate cancer in the TRAMP model.

Ectopical expression of human MUC18 increases metastasis of human prostate cancer cells.

MUC18, a cell adhesion molecule (CAM), has been reported to be a diagnostic marker for the early detection of the metastatic potential of prostate cancers as well as implicated to be an important determinant for mediating the tumorigenesis and metastasis of prostate cancer. To test the hypothesis, we further investigated the possible role of MUC18 in the malignant progression of human prostate cancer. The human MUC18-minus, non-metastatic human prostate cancer LNCaP cells were transfected with the human cytomegalovirus immediate-early gene (HCMV-IE) promoter-driven human MUC18 (huMUC18) cDNA.
