Advancements in small molecule drug design: A structural perspective.

In this review, we outline recent advancements in small molecule drug design from a structural perspective. We compare protein structure prediction methods and explore the role of the ligand binding pocket in structure-based drug design. We examine various structural features used to optimize drug candidates, including functional groups, stereochemistry, and molecular weight.

Efficiency of Biobran/MGN-3, an Arabinoxylan Rice Bran, in Attenuating Diabetes-Induced Cognitive Impairment of the Hippocampus via Oxidative Stress and IR/Akt/NF-B in Rats.

Type 2 diabetes mellitus (T2DM) is a common metabolic disease accompanied by cognitive impairment, hippocampal malfunctioning, and inflammation. Biobran/MGN-3, an arabinoxylan rice bran, has been shown to have an antidiabetic effect in streptozotocin-induced diabetic rats. The present study investigates Biobran's effect against diabetes-induced cognitive impairment and synaptotoxicity in the hippocampus via oxidative stress and the IR/A/NF-B signaling pathway in rats.

Electron withdrawing group-dependent substrate inhibition of an α-ketoamide reductase from Saccharomyces cerevisiae.

Aldo-keto reductases remain enzymes of interest in biocatalysis due to their ability to reduce carbonyls to alcohols stereospecifically. Based on genomic sequence, we identified aldo-keto reductases of a S. cerevisiae strain extracted from an ancient amber sample.

Should Prediabetes be Treated Pharmacologically?

Objective: In this commentary I will evaluate whether prediabetes should be treated pharmacologically. To consider this question, certain information concerning prediabetes is relevant.

Background Information: (1) Prediabetes is not independently associated with cardiovascular disease; the other factors in the metabolic syndrome increase that risk; (2) various tests and criteria for diagnosing prediabetes are recommended, yielding prevalences varying from 6% to 38% depending on which are used; (3) one-third of patients with prediabetes revert to normal over time; (4) up to two-thirds of patients with prediabetes do not develop diabetes; (5) people with prediabetes have insulin resistance and impaired insulin secretion; (6) although pharmacological treatment of the dysglycemia temporarily lowers it, when the drugs are discontinued, incident diabetes develops similarly as that in those who received placebos; (7) when the drugs are discontinued, there are no changes in insulin resistance or impaired insulin secretion; (8) incident diabetes was similar at 10 years in people remaining on metformin in the Diabetes Prevention Program Outcome Study compared with those who did not receive the drug; (9) no current drugs will directly increase insulin secretion (except sulfonylureas and glinides which have not been used to treat prediabetes because of hypoglycemia concerns); (10) sufficient weight loss to lower insulin resistance by nutritional means is challenging and especially difficult to maintain.

COVID-19 Pandemic as an Equalizer of the Health Returns of Educational Attainment for Black and White Americans.

Background: COVID-19 pandemic has immensely impacted the social and personal lives of individuals around the globe. Marginalized-related diminished returns (MDRs) theory suggests that educational attainment shows a weaker protective effect for health and behavioral outcomes for Black individuals compared to White individuals. Previous studies conducted before the COVID-19 pandemic demonstrated diminished returns of educational attainment for Black individuals compared to White individuals.

Incorporation of prior knowledge and habits while solving anagrams.

Games and puzzles provide a valuable context for examining human problemsolving behavior. We recorded and analyzed the sequence of letters viewed by the participants of our study while they were solving anagram puzzles. The goal was to examine and understand how people's linguistic habits and prior knowledge influenced their eye movements.

Medical Practice, the Church and COVID-19.

This issue of JORH explores the importance of religion and spirituality in medical practice, as well as research relating to the Church and its clergy, and finally the lingering effects of COVID-19.

rWTC-MBTA: autologous vaccine prevents metastases via antitumor immune responses.

Background: Autologous tumor cell-based vaccines (ATVs) aim to prevent and treat tumor metastasis by activating patient-specific tumor antigens to induce immune memory. However, their clinical efficacy is limited. Mannan-BAM (MB), a pathogen-associated molecular pattern (PAMP), can coordinate an innate immune response that recognizes and eliminates mannan-BAM-labeled tumor cells.

Comparative evaluation of glomerular morphometric techniques reveals differential technical artifacts between focal segmental glomerulosclerosis and normal glomeruli.

Morphometric estimates of mean or individual glomerular volume (MGV, IGV) have biological implications, over and above qualitative histologic data. However, morphometry is time-consuming and requires expertise limiting its utility in clinical cases. We evaluated MGV and IGV using plastic- and paraffin-embedded tissue from 10 control and 10 focal segmental glomerulosclerosis (FSGS) mice (aging and 5/6th nephrectomy models) using the gold standard Cavalieri (Cav) method versus the 2-profile and Weibel-Gomez (WG) methods and a novel 3-profile method.

Bayesian function registration with random truncation.

In this work, we develop a new set of Bayesian models to perform registration of real-valued functions. A Gaussian process prior is assigned to the parameter space of time warping functions, and a Markov chain Monte Carlo (MCMC) algorithm is utilized to explore the posterior distribution. While the proposed model can be defined on the infinite-dimensional function space in theory, dimension reduction is needed in practice because one cannot store an infinite-dimensional function on the computer.

High Systolic Blood Pressure of High-Income African American Children.

Background: According to the Minorities' Diminished Returns (MDRs) theory, racism may reduce the health returns of family socioeconomic status (SEP) resources such as family income for racial minorities, particularly African Americans, compared to Whites. However, we are unaware of any previous studies on racial variation in the protective effects of family income on children's blood pressure.

Aim: We conducted this study to compare the overall effects of family income on pre-adolescents' systolic and diastolic blood pressure, test racial variation in this effect, and investigate whether racial variation in this regard is due to racial differences in body mass index.

Efficacy of a Smoking Cessation Program for Underserved Ethnic Minority Communities: Results of a Smoking Cessation Trial.

Using a participatory research approach, this study reports the efficacy of the Communities Engaged and Advocating for a Smoke-free Environment (CEASE)-4 intervention offered by the local peers. CEASE-4 is a theory-based tobacco-cessation intervention, tailored to the needs of underserved populations. 842 tobacco users self-selected into: a) self-help ( = 472), b) single-session class ( = 163), and c) four-session class ( = 207).

The new version, Arden Syntax version 3.0, was successfully balloted as part of the audited, consensus-based, iterative HL7 standards development process.

Health disparities among Burmese diaspora: an integrative review.

Unlabelled: Tens of thousands of displaced Burmese ethnic minorities have endured various adversities for over six decades but are largely underserved. This study aimed to illuminate the health impacts of their misfortunes and unmet areas of concern. Using a holistic lens, we conducted an integrative review of 47 papers spanning the years 2004 to 2022 from diverse data sources.

Using Digital Technology to Build COVID-19 Vaccine Confidence: A Qualitative Study among Latinx Parents of Children Aged 5-11 in Under-Resourced Communities across Los Angeles County.

: Latinx school-aged children are more than twice as likely to be infected with and die from COVID-19 as non-Latinx White children in Los Angeles. Although COVID-19 vaccination has the potential to mitigate health disparities exacerbated by the pandemic, vaccination uptake among Latinx children remains limited. MiVacunaLA (MVLA) is a mobile-phone-delivered digital intervention that improved vaccination rates in 12- to 17-year-old Latinx children and parental intention to vaccinate 2- to 11-year-old children.

Physico-chemistry and Cytotoxicity of Tenofovir-Loaded Acid Phosphatase-Responsive Chitosan Nanoparticles.

This study assesses the in vitro release of tenofovir (TFV)-loaded triphosphate (TPP) cross-linked chitosan nanoparticles (NPs) catalyzed by human prostatic acid phosphatase (hPAP) for 24 h. The physico-chemical characterization of the NPs included particle mean diameter (PMD), zeta potential (ζ), percent drug encapsulation efficiency (% EE), Fourier transform infra-red (FTIR) spectroscopy, powder X-ray diffractometry analysis (PXRD), and drug release kinetics. The first-order rate constant (k) and activation energy (E) of the cross-link (TPP) are determined by the integrated rate law and Arrhenius's equations.

Assessing Food Access, Exercise, and Dietary History among Older African American Parishioners During the COVID-19 Pandemic (C-FED Study): Design, Opportunities, Challenges, and Lessons Learned.

Objectives: Unhealthy diets and inadequate exercise are associated with chronic health conditions and excess mortality. Older African Americans do not meet dietary and exercise guidelines, and this may have worsened during the COVID-19 pandemic due to individual and environmental factors, including food insecurity. Studies evaluating these dynamics are essential for developing interventions.

Drug Use, Family Support, and Depressive Symptoms Among Latinx Sexual Minority Men: A Longitudinal Analysis.

Family rejection has negative health consequences for Latinx sexual minority men (LSMM). However, LSMM often reconcile with their families, a phenomenon cross-sectional studies miss. We analyzed longitudinal data from the Healthy Young Men's Study in Los Angeles.

The Association between Adult Sport, Fitness, and Recreational Physical Activity and Number and Age of Children Present in the Household: A Secondary Analysis Using NHANES.
