ABSTRACT

The emergence of COVID-19 resulted from educational institutions to adapt flexible mode of learning. In this type of modality, teacher's teaching styles is one of the crucial factors that may influence the student's motivation in learning. This quantitative descriptive-correlation study investigated both the students' perception on what type of teaching style their teachers have and students' level of motivation in learning Psychology subjects. Data was collected from 349 students taking BS Psychology from Dalubhasaan ng Lungsod ng San Pablo, a locally funded college in the City of San Pablo, Philippines. Results shows that as perceived by the students, 86% of their teachers used learner-centered approach while the remaining 14% used teacher-centered approach. Participation in the learning process is the most common approach used by teachers for specific teaching styles, followed by personalizing experience, relating to experience, and climate building, in that order. Students' motivation to learn psychology was found to be high to very high, as was their self-regulation level. Learner-centered, participation in the learning process, personalizing experience, relating to experience, and climate building was found to have low positive correlation to intrinsic motivation and task value but have negligible correlation to extrinsic motivation and self-regulation.

ABSTRACT

In this meta-analysis, we estimate the effectiveness of hybrid language instruction overall and across a number of moderator variables by aggregating effect sizes from 11 studies with 34 samples. Results suggest hybrid language instruction can be just as effective as traditional face-to-face (f2f) instruction, as indicated by the negligible differences between hybrid courses and traditional f2f courses (d = .14). Furthermore, studies employing within-group designs indicate that students in hybrid language classes can improve their language skills considerably (d = 1.47). This is a positive finding given that many institutions have experienced a surge in hybrid teaching due to the COVID-19 pandemic. We also report on a number of moderator variables that can impact the effectiveness of hybrid language courses, including (a) the amount of reduction in f2f time, (b) the use of online activities provided by textbook publishers, (c) the use of a learning management system, (d) advances in digital technologies, (e) the targeted language skills (e.g., speaking, writing), and (f) whether the data come from initial or subsequent iterations of a hybrid course. Additionally, we offer directions for future research regarding the substantive and methodological issues in the hybrid language instruction domain.

ABSTRACT

Introduction: Gattinoni et al. have recently introduced a new internal milieu parameter: the “alactic base excess” (ABE). This variable is obtained by applying the following equation: ABE mmol/L = standard base excess (SBE) mmol/L + lactate mmol/L, being standard base excess mmol/L = [bicarbonate mmol/L - 24.8 mmol/L] + 16.2 mmol/L x (pH - 7.4). In a clinical setting, a negative ABE value is directly related to fix acid retention, and is associated with higher mortality in septic patients. Hemoperfusion (HPF) is an extracorporeal technique which involves the passage of blood (or plasma) through an adsorption cartridge, where solutes are removed by direct binding to the sorbent material. Then, we decided to evaluate if HPF could modify negative ABE value in sepsis. Methods: Basal values of ABE, SBE and lactate (mean, SD) were obtained. The difference between these parameters values before and after 4 HPF (HA330) sessions (delta value) was evaluated. Student and Wilcoxon tests were applied for data analyses Results: From 32 patients (age: 57±13, male 69%) suffering from respiratory insufficiency secondary to COVID-19 (RIC) who were treated with HPF (HA330) in the critical care unit of Clinica de la Mujer, Bogotá (Colombia), 6 presented metabolic acidosis (pH:7.37±0.1, pCO2: 36±14 mmHg, bicarbonate:20.5±3 mmol/L) with negative ABE value (-2.7±1) composed by negative SBE (- 4.7±1) and high lactate serum value (2±0.7 mmol/L). Delta ABE, SBE and lactate were: 7.7 (p:0.005), 6.1 (p:0.003) and 1.6 (p:NS), respectively. Thus, negative ABE was significantly reversed by HPF, due to SBE positivization without significant change in lactate. Conclusions: Negative alactic parameter was significantly reversed by HPF in septic patients. No conflict of interest

ABSTRACT

In this meta‐analysis, we estimate the effectiveness of hybrid language instruction overall and across a number of moderator variables by aggregating effect sizes from 11 studies with 34 samples. Results suggest hybrid language instruction can be just as effective as traditional face‐to‐face (f2f) instruction, as indicated by the negligible differences between hybrid courses and traditional f2f courses (d = .14). Furthermore, studies employing within‐group designs indicate that students in hybrid language classes can improve their language skills considerably (d = 1.47). This is a positive finding given that many institutions have experienced a surge in hybrid teaching due to the COVID‐19 pandemic. We also report on a number of moderator variables that can impact the effectiveness of hybrid language courses, including (a) the amount of reduction in f2f time, (b) the use of online activities provided by textbook publishers, (c) the use of a learning management system, (d) advances in digital technologies, (e) the targeted language skills (e.g., speaking, writing), and (f) whether the data come from initial or subsequent iterations of a hybrid course.

ABSTRACT

Pandemic Covid-19 has change learning process to use online learning platform to limit interaction between participant of learning and reduce the Covid-19. This shifting has a major impact on education. Even though, many things have been done by education institution, lecturers, and students in adapting to online learning. In this study focus to check the effect of online learning on students' ability to understand the learning process. In this research, we use quantitative approach. To collect the data, this study uses a questionnaire method and in data analysis this study uses descriptive methods. In the results of this research can conclude that there is a positive influence from online learning on student's ability to understand the material. Therefore, higher education institution have to consider online learning to be good so that in the future it can continue to be developed or upgrade so that it can make it easier for students to understand the material and learn effectively and efficiently. © 2021 IEEE.

ABSTRACT

The therapeutic targeting of the nonstructural protein 5B (NS5B) RNA-dependent RNA polymerase (RdRp) of the Hepatitis C Virus (HCV) with nucleotide analogs led to a deep understanding of this enzymes structure, function and substrate specificity. Unlike previously studied DNA polymerases including the reverse transcriptase of Human Immunodeficiency Virus, development of biochemical assays for HCV RdRp proved challenging due to low solubility of the full-length protein and inefficient acceptance of exogenous primer/templates. Despite the poor apparent specific activity, HCV RdRp was found to support rapid and processive transcription once elongation is initiated in vitro consistent with its high level of viral replication in the livers of patients. Understanding of the substrate specificity of HCV RdRp led to the discovery of the active triphosphate of sofosbuvir as a nonobligate chain-terminator of viral RNA transcripts. The ternary crystal structure of HCV RdRp, primer/template, and incoming nucleotide showed the interaction between the nucleotide analog and the 2'-hydroxyl binding pocket and how an unfit mutation of serine 282 to threonine results in resistance by interacting with the uracil base and modified 2'-position of the analog. Host polymerases mediate off-target toxicity of nucleotide analogs and the active metabolite of sofosbuvir was found to not be efficiently incorporated by host polymerases including the mitochondrial RNA polymerase (POLRMT). Knowledge from studying inhibitors of HCV RdRp serves to advance antiviral drug discovery for other emerging RNA viruses including the discovery of remdesivir as an inhibitor of severe acute respiratory syndrome coronavirus 2 (SARS-CoV2), the virus that causes COVID-19.

ABSTRACT

BACKGROUND: Up to 75% of hip fracture patients never recover to their pre-fracture functional status. Supervised exercise that includes strength training can improve functional recovery after hip fracture. The role of testosterone replacement for augmenting the effects of exercise in older women after hip fracture is unknown. METHODS: The Starting Testosterone and Exercise after Hip Injury (STEP-HI) Study is a 6-month Phase 3 multicenter randomized placebo-controlled trial designed to compare supervised exercise (EX) plus 1% testosterone topical gel, with EX plus placebo gel, and with enhanced usual care (EUC). Female hip fracture patients age ≥ 65 years are being recruited from clinical centers across the United States. Participants are community dwelling and enrolled within 24 weeks after surgical repair of the fracture. The EX intervention is a center-based program of progressive resistance training. The EUC group receives a home exercise program and health education. Participants receive dietary counseling, calcium and vitamin D. The primary outcome is the Six Minute Walk Distance. Secondary outcomes include physical performance measures, self-reported function and quality of life, and dual energy x-ray absorptiometry measures of body composition and bone mineral density. RESULTS: Enrollment, interventions, and follow-up are ongoing. We describe the impact of the coronavirus disease 2019 pandemic on the trial, including modifications made to allow continuation of the interventions and outcome data collection using remote video and audio technology. CONCLUSIONS: Results from the STEP-HI study are expected to have important clinical and public health implications for management of the growing population of hip fracture patients.

ABSTRACT

AIMS: Angiotensin-converting enzyme 2 (ACE2) is the cellular entry point for severe acute respiratory syndrome coronavirus (SARS-CoV-2)-the cause of coronavirus disease 2019 (COVID-19). However, the effect of renin-angiotensin system (RAS)-inhibition on ACE2 expression in human tissues of key relevance to blood pressure regulation and COVID-19 infection has not previously been reported. METHODS AND RESULTS: We examined how hypertension, its major metabolic co-phenotypes, and antihypertensive medications relate to ACE2 renal expression using information from up to 436 patients whose kidney transcriptomes were characterized by RNA-sequencing. We further validated some of the key observations in other human tissues and/or a controlled experimental model. Our data reveal increasing expression of ACE2 with age in both human lungs and the kidney. We show no association between renal expression of ACE2 and either hypertension or common types of RAS inhibiting drugs. We demonstrate that renal abundance of ACE2 is positively associated with a biochemical index of kidney function and show a strong enrichment for genes responsible for kidney health and disease in ACE2 co-expression analysis. CONCLUSION: Our results indicate that neither hypertension nor antihypertensive treatment is likely to alter the expression of the key entry receptor for SARS-CoV-2 in the human kidney. Our data further suggest that in the absence of SARS-CoV-2 infection, kidney ACE2 is most likely nephro-protective but the age-related increase in its expression within lungs and kidneys may be relevant to the risk of SARS-CoV-2 infection.

ABSTRACT

Angiotensin converting enzyme 2 (ACE2) is the cellular entry point for severe acute respiratory syndrome coronavirus (SARS-CoV-2) - the cause of COVID-19 disease. It has been hypothesized that use of renin-angiotensin system (RAS) inhibiting medications in patients with hypertension, increases the expression of ACE2 and thereby increases the risk of COVID-19 infection and severe outcomes or death. However, the effect of RAS-inhibition on ACE2 expression in human tissues of key relevance to blood pressure regulation and COVID-19 infection has not previously been reported. We examined how hypertension, its major metabolic co-phenotypes and antihypertensive medications relate to ACE2 renal expression using information from up to 436 patients whose kidney transcriptomes were characterised by RNA-sequencing. We further validated some of the key observations in other human tissues and/or a controlled experimental model. Our data reveal increasing expression of ACE2 with age in both human lungs and the kidney. We show no association between renal expression of ACE2 and either hypertension or common types of RAS inhibiting drugs. We demonstrate that renal abundance of ACE2 is positively associated with a biochemical index of kidney function and show a strong enrichment for genes responsible for kidney health and disease in ACE2 co-expression analysis. Collectively, our data indicate that neither hypertension nor antihypertensive treatment are likely to alter individual risk of SARS-CoV-2 infection or influence clinical outcomes in COVID-19 through changes of ACE2 expression. Our data further suggest that in the absence of SARS-CoV-2 infection, kidney ACE2 is most likely nephro-protective but the age-related increase in its expression within lungs and kidneys may be relevant to the risk of SARS-CoV-2 infection.
