Factors Leading to Students’ Satisfaction in the Higher Learning Institutions

There is an increasing need to understand factors that affect satisfaction of students with learning. This study will explore the relationship between student satisfaction and teacher-student relationship, teacher preparedness, campus support facilities and experiences provided by the institute to the students. Study is a necessary activity that most people must engage in for much of their lives to support themselves and their families; however, motivation and student satisfaction vary for students. Some students are motivated by a sense of accomplishment, some by helping others, and others by personal fulfillment. Some students get satisfied by personality grooming, personal values, and psychological needs fulfillment. The data was collected through questionnaire from the students of selected universities. This study focuses on factors that influence student satisfaction for the purpose of improving quality and thereby better performance.

Expanding DdCBE-mediated targeting scope to aC motif preference in rat

An animal model harboring pathogenic mitochondrial DNA (mtDNA) mutations is important to understand the biological links between mtDNA variation and mitochondrial diseases. DdCBE, a DddA-derived cytosine base editor, has been utilized in zebrafish, mice, and rats for tC sequence-context targeting and human mitochondrial disease modeling. However, human pathogenic mtDNA mutations other than the tC context cannot be manipulated. Here, we screened the combination of different DdCBE pairs at pathogenic mtDNA mutation sites with nC (n for a, g, or c) context and identified that the left-G1333C (L1333C) + right G1333N (R1333N) pair could mediate C⋅G-to-T⋅A conversion effectively at aC sites in rat C6 cells. The editing efficiency at disease-associated mtDNA mutation sites within aC context was further confirmed to be up to 67.89% in vivo. Also, the installed disease-associated mtDNA mutations were germline transmittable. Moreover, the edited rats showed impaired cardiac function and mitochondrial function, resembling human mitochondrial disease symptoms. In summary, for the first time, we expanded the DdCBE targeting scope to an aC motif and installed the pathogenic mutation in rats to model human mitochondrial diseases

Empagliflozin in Patients with Chronic Kidney Disease

Background The effects of empagliflozin in patients with chronic kidney disease who are at risk for disease progression are not well understood. The EMPA-KIDNEY trial was designed to assess the effects of treatment with empagliflozin in a broad range of such patients. Methods We enrolled patients with chronic kidney disease who had an estimated glomerular filtration rate (eGFR) of at least 20 but less than 45 ml per minute per 1.73 m(2) of body-surface area, or who had an eGFR of at least 45 but less than 90 ml per minute per 1.73 m(2) with a urinary albumin-to-creatinine ratio (with albumin measured in milligrams and creatinine measured in grams) of at least 200. Patients were randomly assigned to receive empagliflozin (10 mg once daily) or matching placebo. The primary outcome was a composite of progression of kidney disease (defined as end-stage kidney disease, a sustained decrease in eGFR to < 10 ml per minute per 1.73 m(2), a sustained decrease in eGFR of & GE;40% from baseline, or death from renal causes) or death from cardiovascular causes. Results A total of 6609 patients underwent randomization. During a median of 2.0 years of follow-up, progression of kidney disease or death from cardiovascular causes occurred in 432 of 3304 patients (13.1%) in the empagliflozin group and in 558 of 3305 patients (16.9%) in the placebo group (hazard ratio, 0.72; 95% confidence interval [CI], 0.64 to 0.82; P < 0.001). Results were consistent among patients with or without diabetes and across subgroups defined according to eGFR ranges. The rate of hospitalization from any cause was lower in the empagliflozin group than in the placebo group (hazard ratio, 0.86; 95% CI, 0.78 to 0.95; P=0.003), but there were no significant between-group differences with respect to the composite outcome of hospitalization for heart failure or death from cardiovascular causes (which occurred in 4.0% in the empagliflozin group and 4.6% in the placebo group) or death from any cause (in 4.5% and 5.1%, respectively). The rates of serious adverse events were similar in the two groups. Conclusions Among a wide range of patients with chronic kidney disease who were at risk for disease progression, empagliflozin therapy led to a lower risk of progression of kidney disease or death from cardiovascular causes than placebo
