Implementation science in higher education: Identifying key determinants in the selection of evidence-based alcohol and substance prevention and treatment.

Introduction: Although there are evidence-based strategies (EBSs) for alcohol and other drug (AOD) prevention and treatment for college students, there has been little focus on evaluating AOD EBS implementation in higher education. The use of implementation strategies in higher education may help bridge the gap between research and practice and improve students' access to EBSs. However, it is important to first understand determinants of AOD EBS program implementation to support AOD EBS selection and implementation strategy selection.

Drivers of stunting and wasting across serial cross-sectional household surveys of children under 2 years of age in Pakistan: potential contribution of ecological factors.

Background: The impact of direct and indirect drivers on linear growth and wasting in young children is of public health interest. While the contributions of poverty, maternal education, empowerment and birth weight to early childhood growth are well recognized, the contribution of environmental factors like heat, precipitation, agriculture outputs and food security in comparable datasets is less well established.

Objectives: To investigate the association of length-for-age z-score (LAZ) and weight-for-length z-score (WLZ) with various indicators among children under 2 years of age in Pakistan using representative household level nutrition surveys and ecological datasets.

Association between dietary fructose and human colon DNA methylation: implication for racial disparities in colorectal cancer risk using a cross-sectional study.

Background: An increasing body of evidence has linked fructose intake to colorectal cancer (CRC). African American (AA) adults consume greater quantities of fructose and are more likely to develop right-side colon cancer than European American (EA) adults.

Objective: We examined the hypothesis that fructose consumption leads to epigenomic and transcriptomic differences associated with CRC tumor biology.

LGR4 is essential for maintaining β-cell homeostasis through suppression of RANK.

Objective: Loss of functional β-cell mass is a major cause of diabetes. Thus, identifying regulators of β-cell health is crucial for treating this disease. The In this study, we assessed the regulation of Lgr4 in islets, and the role of LGR4 and LGR4/RANK stoichiometry in β-cell health under basal and stress-induced conditions, in vitro and in vivo.

Kinetically controlled irreversible unfolding of esterase from Clostridium acetobutylicum: Thermal deactivation kinetics and structural studies.

This study involves the thermal characterization of Ca-Est, an esterase from Clostridium acetobutylicum which has been previously found to exhibit maximum specific activity at 60 °C. In the present study, Ca-Est showed maximum stability at 30 °C with almost 75 % of its initial activity being retained after incubation for 5 h and the stability decreased with increasing temperature. Analysis of the thermodynamic parameters revealed that the deactivation of Ca-Est is endothermic and enthalpically favored.

Cys44 of SARS-CoV-2 3CL affects its catalytic activity.

SARS-CoV-2 encodes a 3C-like protease (3CL) that is essential for viral replication. This cysteine protease cleaves viral polyproteins to release functional nonstructural proteins, making it a prime target for antiviral drug development. We investigated the inhibitory effects of halicin, a known c-Jun N-terminal kinase inhibitor, on 3CL.

RNAi-mediated knockdown of HcCAT2 depresses the adaptive capacity of Hyphantria cunea larvae to cytisine and coumarin.

The diversity of host plants is an important reason for the global spread of Hyphantria cunea. However, no studies have explored the role of the antioxidant defense system with catalase (CAT) as the core at the molecular level in the adaptation of the H. cunea to host plant secondary metabolites.

Phylogenomic insights into the taxonomy, ecology, and mating systems of the lorchel family Discinaceae (Pezizales, Ascomycota).

Lorchels, also known as false morels (Gyromitra sensu lato), are iconic due to their brain-shaped mushrooms and production of gyromitrin, a deadly mycotoxin. Molecular phylogenetic studies have hitherto failed to resolve deep-branching relationships in the lorchel family, Discinaceae, hampering our ability to settle longstanding taxonomic debates and to reconstruct the evolution of toxin production. We generated 75 draft genomes from cultures and ascomata (some collected as early as 1960), conducted phylogenomic analyses using 1542 single-copy orthologs to infer the early evolutionary history of lorchels, and identified genomic signatures of trophic mode and mating-type loci to better understand lorchel ecology and reproductive biology.

The SGLT2 inhibitor remogliflozin induces vasodilation in the femoral artery of rabbits via activation of a Kv channel, the SERCA pump, and the cGMP signaling pathway.

This study explored the vasodilatory mechanisms of the sodium-glucose cotransporter-2 inhibitor remogliflozin using femoral arteries of rabbits. Remogliflozin dilated femoral arterial rings pre-contracted with phenylephrine in a concentration-dependent manner. Pretreatment with the Ca-sensitive K channel inhibitor (paxilline), the ATP-sensitive K channel inhibitor (glibenclamide), or the inwardly rectifying K channel inhibitor (Ba) did not alter the vasodilatory effect.

Prospective and retrospective analysis of whole slide images of sentinel and targeted lymph node frozen sections in breast cancer.

Different types of digital modalities are currently available for frozen section (FS) evaluation in surgical pathology practice. However, there are limited studies that demonstrate the potential of whole slide imaging (WSI) as a robust digital pathology option for FS FS diagnosis. In the current study, we compared the diagnostic accuracy achieved with WSI to that achieved with Light Microscopy (LM) for evaluating FSs of axillary sentinel lymph nodes (SLNs) and clipped lymph nodes (LNs) from breast cancer patients using two modalities.

Characterization of Bifidobacterium bifidum growth and metabolism on whey protein phospholipid concentrate.

Whey protein phospholipid concentrate (WPPC) is a co-product generated during the manufacture of whey protein isolate. WPPC is depleted of simple sugars but contains numerous glycoconjugates embedded in the milk fat globule membrane, suggesting this fraction may serve as a carbon source for growth of bifidobacteria commonly enriched in breast fed infants. In this work, we demonstrate that WPPC can serve as a sole carbon source for the growth of Bifidobacterium bifidum, a species common to the breastfed infant and routinely used as a probiotic.
