The transmission of COVID-19 has sent Malaysia into cycles of tightening and relaxation of movement control, which are still continuing currently in line with local fluctuations of new COVID-19 cases. During movement control, measures comprising physical distancing, hand cleaning or sanitizing, and sanitization of premises are consistently implemented while self-isolation and travel restrictions are adaptively enforced. This study aims to examine if the control of COVID-19 transmission has an effect on the national influenza occurrences as some measures for COVID-19 control are similar to those for influenza.

For this study, data of weekly new cases of influenza and COVID-19 were obtained from official platforms for non-parametric statistical analysis.

This study compared the influenza occurrences before and after the onset of COVID-19 using the Mann-Whitney U-test and explored Spearman's correlations between COVID-19 and influenza incidences after the onset of COVID-19.

It shows that influenza incidences before and after the onset of COVID-19 were significantly different and that influenza cases have significantly reduced after the onset of COVID-19. The weekly cases of influenza and COVID-19 were significantly and negatively correlated.

This study underscores the co-benefits of COVID-19 control measures and alleviates the concern for the risk of COVID-19 and influenza co-infection.

Educators often struggle to sustain students' motivation during adolescence. Students may view school tasks as insignificant because learning, achievement, and success feel detached from valued social connections. Previous findings in the study of development demonstrate that young people derive meaning from key sources of social support and connection. Finding ways to link how students approach their educational goals to meaningful social connections may strengthen responses to daily learning opportunities with positive implications for achievement.

A randomized-controlled experiment and daily diary survey evaluated the consequences of guiding students to conceptualize educational pursuits as linked to their social connections. A group of ninth-grade students in the United States (N=39; 58.97% girls, 30.77% boys, 2.56% non-binary, 7.69% did not disclose) were randomly assigned to one of two brief programs designed to cultivate goals and motivation.

Participants randomly assigned to a healthy achievement condition (including an emphasis on the importance of social support and connection as part of achievement and success) reported more productive responses to daily academic difficulty than participants in a standard motivation condition on a daily diary survey over one year after the program. This led to an indirect increase in actual daily support, which was associated with earning higher grades.

The results suggest that a reconceptualization of education as an endeavor grounded in social connection would help keep students engaged in learning.

The present review subsequently attempts to address the evolving molecular, cellular and systemic mechanisms of NeuroCOVID, which we have classified as the acute and long-term neurological effects of COVID-19. We place particular emphasis on cerebrovascular, demyelinating and encephalitic presentations, which have been reported. Several mechanisms are presented, especially the involvement of a "cytokine storm". We explore the genetic and demographic factors that may predispose individuals to NeuroCOVID. The increasingly evident long-term neurological effects are also presented, including the impact of the virus on cognition, autonomic function and mental wellbeing, which represent an impending burden on already stretched healthcare services. We subsequently reinforce the need for cautious surveillance, especially for those with predisposing factors, with effective clinical phenotyping, appropriate investigation and, if possible, prompt treatment. This will be imperative to prevent downstream neurological sequelae, including those related to the long COVID phenotypes that are being increasingly recognised.Cell migration is oriented by cues from the environment. Such cues are read and interpreted by the cell and translated into a reorganization of the migration machinery to steer migration. Receptors at the cell surface are central to detect these cues. These receptors can be internalized and this plays an important role in the decision-making process leading to choosing a migration direction. Independently of endocytosis, recent findings suggest that regulation of these receptors and translation of the information they carry into a phenotype is facilitated by their clustering at discrete locations of the plasma membrane. Clathrin-coated structures are archetypal clustering assemblies and thus provide the cell with a finely tunable mechanism for controlling receptor availability. In addition, clathrin-coated structures can be regulated by many factors playing a role in cell migration and thus take part in feedback loop mechanisms that are instrumental in defining a migration direction.

SARS-Cov-2 predisposes patients to thrombotic complications, due to excessive inflammation, endothelial dysfunction, platelet activation, and coagulation/fibrinolysis disturbances. The aim of the present study was to evaluate clinical characteristics and prognostic impact of SARS-CoV-2 positivity among STEMI patients undergoing primary percutaneous coronary intervention (PPCI).

We selected SARS-CoV-2 positive patients included in the ISACS-STEMI COVID-19, a retrospective multicenter European registry including 6609 STEMI patients treated with PPCI from March 1st until April 30th, in 2019 and 2020. As a reference group, we randomly sampled 5 SARS-Cov-2 negative patients per each SARS-CoV-2 positive patient, individually matched for age, sex, and hospital/geographic area. Study endpoints were in-hospital mortality, definite stent thrombosis, heart failure.

Our population is represented by 62 positive SARS-CoV-2 positive patients who were compared with a matched population of 310 STEMI patients. No signifigher rates of in-stent thrombosis and heart failure.BTK (Bruton's tyrosine kinase) inhibitors are the most promising drugs for the treatment of hematological tumors. A high selectivity of BTK inhibitors ensures reduced side effects from off-targeting. Accordingly, here, based on Zanubrutinib, we designed and synthesized a new range of imidazopyrazole-3-carboxamide derivatives as novel BTK inhibitors that retained the amide group for improved selectivity. These compounds revealed potent inhibitory activity against BTK in vitro. Remarkably, compounds 12a (IC50 5.2 nM) and 18a (IC50 4.9 nM) possessed the highest kinase selectivity. Both of these effectively inhibited the auto-phosphorylation of BTK, blocked the cell cycle in G0/G1 phase, and induced apoptosis in the TMD8 cells. In a TMD8 cells xenograft model, a twice-daily dose of compound 12a at 25 mg/kg and a thrice-daily dose of compound 18a at 15 mg/kg significantly suppressed the tumor growth without obvious toxicity. Collectively, 12a and 18a are the potential selective BTK inhibitors that can be developed further.Antimicrobial stewardship is imperative when treating bacterial infections because the misuse and overuse of antibiotics have caused pathogens to develop life-threatening resistance mechanisms. The New Delhi metallo-beta-lactamase (NDM-1) is one of many enzymes that enable bacterial resistance. NDM-1 is a more recently discovered beta-lactamase with the ability to inactivate a wide range of beta-lactam antibiotics. Multiple NDM-1 inhibitors have been designed and tested; however, due to the complexity of the NDM-1 active site, there is currently no inhibitor on the market. Consequently, an infection caused by bacteria possessing the gene for the NDM-1 enzyme is a serious and potentially fatal complication. An abundance of research has been invested over the past decade in search of an NDM-1 inhibitor. This review aims to summarize various NDM-1 inhibitor designs that have been developed in recent years.Medulloblastoma - highly aggressive and heterogeneous tumours of the cerebellum - account for 15-20% of all childhood brain tumours, and are the most common high-grade childhood embryonal tumour of the central nervous system. Herein, potent in vitro anticancer activity against two established medulloblastoma cell lines of the sonic hedgehog subgroup, namely DAOY (p53 mutant) and ONS-76 (p53 wild type), has been achieved. A number of first-generation diarylamides and diarylureas were evaluated and activity is likely to be, in-part, conformation-dependent. The most active compound from this first-generation set of compounds, 1-naphthyl derivative 4b, was selected and a second-generation of compounds were optimised and tested for activity against the medulloblastoma cell lines. This process resulted in drug-like compounds with up to sixty times the activity (sub-micromolar) of the first-generation - thus providing potent new leads for further study.Protease activated receptor 4 (PAR4) is an important target in antiplatelet therapy to reduce the risk of heart attack and thrombotic complications in stroke. PAR4 antagonists can prevent harmful and stable thrombus growth, while retaining initial thrombus formation, by acting on the late diffusion stage of platelet aggregation, and may provide a safer alternative to other antiplatelet agents. To date, only two PAR4 antagonists, BMS-986120 and BMS-986141 have entered clinical trials for thrombosis. Thus, the development of a potent and selective PAR4 antagonist with a novel chemotype is highly desirable. In this study, we explored the activity of quinazolin-4(3H)-one-based PAR4 antagonists, beginning with their IDT analogues. By repeated structural optimisation, we developed a series of highly selective PAR4 antagonists with nanomolar potency on human platelets. Of these, 13 and 30g, with an 8-benzo[d]thiazol-2-yl-substituted quinazolin-4(3H)-one structure, showed optimal activity (h. PAR4-AP PRP IC50 = 19.6 nM and 6.59 nM, respectively) on human platelets. Furthermore, 13 and 30g showed excellent selectivity for PAR4 versus PAR1 and other receptors (IC50s > 10 μM) on human platelets. And 13 and 30g were lack of cross-reactivity for PAR1 or PAR2 (PAR1 AP FLIPR IC50 > 3162 nM, PAR2 AP FLIPR IC50 > 1000 nM) in the calcium mobilization assays. Metabolic stability assays and cytotoxicity tests of 13 and 30g indicated that these compounds could sever as promising drug candidates for the development of novel PAR4 antagonists. In summary, the quinazolin-4(3H)-one-based analogues are the first reported chemotypes with excellent activity and selectivity against PAR4, and, in the current study, we expanded the structural diversity of PAR4 antagonists. The two compounds, 13 and 30g, found in our study could be promising starting points with great potential for further research in antiplatelet therapy.
