TAMPA: interpretable analysis and visualization of metagenomics-based taxon abundance profiles.

Background: Metagenomic taxonomic profiling aims to predict the identity and relative abundance of taxa in a given whole-genome sequencing metagenomic sample. A recent surge in computational methods that aim to accurately estimate taxonomic profiles, called taxonomic profilers, has motivated community-driven efforts to create standardized benchmarking datasets and platforms, standardized taxonomic profile formats, and a benchmarking platform to assess tool performance. While this standardization is essential, there is currently a lack of tools to visualize the standardized output of the many existing taxonomic profilers.

Synthesis of Bispecific Antibody Conjugates Using Functionalized Poly-ADP-ribose Polymers.

Poly-ADP-ribose (PAR) is a natural type of polymer derived from enzymatic reactions catalyzed by cellular poly(ADP-ribose) polymerases (PARPs). Given its notable solubility and biocompatibility, the PAR polymer may function as effective carriers for therapeutics in addition to modulating biomolecular interactions in cells. To explore its therapeutic potential, we herein developed a PAR polymer-based bispecific antibody targeting both human epidermal growth factor receptor 2 (HER2) and T-cell CD3 antigens.

Regular Cannabis Use During the First Year of the Pandemic: Studying Trajectories Rather Than Prevalence.

Introduction: Cannabis use in the U.S. rose early in the COVID-19 pandemic, but it is unclear whether that rise was temporary or permanent.

The gut-brain axis and cognitive control: A role for the vagus nerve.

Survival requires the integration of external information and interoceptive cues to effectively guide advantageous behaviors, particularly foraging and other behaviors that promote energy acquisition and consumption. The vagus nerve acts as a critical relay between the abdominal viscera and the brain to convey metabolic signals. This review synthesizes recent findings from rodent models and humans revealing the impact of vagus nerve signaling from the gut on the control of higher-order neurocognitive domains, including anxiety, depression, reward motivation, and learning and memory.

Investigating the factors that explain white matter hyperintensity load in older Indians.

White matter hyperintensities are areas of hyperintense signal on MRI that typically represent cerebrovascular pathology. While focal white matter hyperintensities are common among older individuals, extensive white matter hyperintensities have been found to accelerate the progression of dementia. However, little is currently known about how various socioeconomic, health, lifestyle and environmental factors affect the severity of these lesions, particularly in low- and middle-income countries such as India.

Lack of accelerated ovarian aging in a follicle-stimulating hormone receptor haploinsufficiency model.

Follicle-stimulation hormone (FSH) and FSH receptor (FSHR) signaling is essential for lifelong ovarian and endocrine functions in females. Previous studies have reported that haploinsufficiency in female mice led to accelerated ovarian aging, including anticipated progressive fertility decline, irregular estrus cycles, increased follicular atresia and premature ovarian failure at 7 to 9 months of age. Interestingly, these phenotypes resemble key characteristics of human menopause and thus haploinsufficiency was proposed as a promising research mouse model of menopause.

Zeta diversity patterns in metabarcoded lotic algal assemblages as a tool for bioassessment.

Assessments of the ecological health of algal assemblages in streams typically focus on measures of their local diversity and classify individuals by morphotaxonomy. Such assemblages are often connected through various ecological processes, such as dispersal, and may be more accurately assessed as components of regional-, rather than local-scale assemblages. With recent declines in the costs of sequencing and computation, it has also become increasingly feasible to use metabarcoding to more accurately classify algal species and perform regional-scale bioassessments.

Geospatial techniques for monitoring and mitigating climate change and its effects on human health.

This article begins by briefly examining the multitude of ways in which climate and climate change affect human health and wellbeing. It then proceeds to present a quick overview of how geospatial data, methods and tools are playing key roles in the measurement, analysis and modelling of climate change and its effects on human health. Geospatial techniques are proving indispensable for making more accurate assessments and estimates, predicting future trends more reliably, and devising more optimised climate change adaptation and mitigation plans.

Global, regional and national trends in statin utilisation in high-income and low/middle-income countries, 2015-2020.

Objective: Prior studies have reported inequitable global access to essential medicines for cardiovascular disease (CVD) prevention, especially statins. Here we examine recent trends and disparities in statin utilisation at the income group, regional and country levels.

Design: Ecological study.

Synthesis and biological evaluation of novel SN38-glucose conjugate for colorectal cancer treatment.

7-Ethyl-10-hydroxycamptothecin (SN38), the bioactive metabolite of irinotecan (CPT-11), has been shown to be 100-1000 times more effective than CPT-11. However, the poor water solubility and bioavailability of SN38 constrained its clinical application. In this study, we synthesized a novel SN38-glucose conjugate (FSY04) to address this issue.

Gender affirming hormone therapy dosing behaviors among transgender and nonbinary adults.

Gender-affirming hormones have been shown to improve psychological functioning and quality of life among transgender and nonbinary (trans) people, yet, scant research exists regarding whether and why individuals take more or less hormones than prescribed. Drawing on survey data from 379 trans people who were prescribed hormones, we utilized multivariable logistic regression models to identify factors associated with hormone-dosing behaviors and content analysis to examine the reasons for dose modifications. Overall, 24% of trans individuals took more hormones than prescribed and 57% took less.

Dynamic regulation of gonadal transposon control across the lifespan of the naturally short-lived African turquoise killifish.

Although germline cells are considered to be functionally "immortal," both the germline and supporting somatic cells in the gonad within an organism experience aging. With increased age at parenthood, the age-related decline in reproductive success has become an important biological issue for an aging population. However, molecular mechanisms underlying reproductive aging across sexes in vertebrates remain poorly understood.

Macroeconomic consequences of the COVID-19 pandemic.

We estimate the economic impacts of COVID-19 in the U.S. using a disaster economic consequence analysis framework implemented by a dynamic computable general equilibrium (CGE) model.

An overview of PROTACs: a promising drug discovery paradigm.

Proteolysis targeting chimeras (PROTACs) technology has emerged as a novel therapeutic paradigm in recent years. PROTACs are heterobifunctional molecules that degrade target proteins by hijacking the ubiquitin-proteasome system. Currently, about 20-25% of all protein targets are being studied, and most works focus on their enzymatic functions.

Discovery of highly potent and selective 7-ethyl-10-hydroxycamptothecin-glucose conjugates as potential anti-colorectal cancer agents.

7-Ethyl-10-hydroxycamptothecin (SN38), a highly potent metabolite of irinotecan, has an anticancer efficacy 100-1000 folds more than irinotecan . However, the clinical application of SN38 has been limited due to the very narrow therapeutic window and poor water solubility. Herein, we report the SN38-glucose conjugates (Glu-SN38) that can target cancer cells due to their selective uptake glucose transporters, which are overexpressed in most cancers.

Prevalence and correlates of skin examination among ethnically diverse young adult survivors of childhood cancer.

Background: Skin cancer is the most common secondary malignancy among young adult childhood cancer survivors (YA-CCS). Skin examination to detect skin cancer early (including melanoma as well as basal or squamous cell skin cancers), both physician-based (PSE) and self-skin exam (SSE), is recommended, particularly for radiotherapy-exposed YA-CCS who are at high risk of developing skin cancer.

Methods: Awareness and prevalence of skin examination and demographic, clinical, and healthcare correlates were examined in a population-based sample of YA-CCS with diverse cancer types excluding melanoma.

Monocyte Chemoattractant Protein-1-Supplemented Plasma Enhances Adiponectin and Adipogenesis-Related Gene Expression.

Increasing adipogenesis has been explored to treat metabolic diseases and atherosclerosis through the release of adiponectin. The effects and mechanism of platelet-rich plasma treatment on fat graft survival and adipogenesis have not been clarified. Here, we aimed to study the effects of monocyte chemoattractant protein-1 (MCP-1)-supplemented plasma on adipogenesis-related gene expression and adiponectin levels.

Paraventricular nucleus-Medullary interactions: How they help enable endocrine responses to metabolic stress.

The paraventricular hypothalamic nucleus (PVH) organizes neuroendocrine and autonomic responses to rapidly and slowly developing metabolic stressors that limit their impact on energy balance. The PVH together with the lateral hypothalamic area, and the arcuate and dorsomedial nuclei form a network that is defined by its inputs from medullary catecholamine neurons. These medullary neurons convey important glycemia and glucocorticoid feedback information that is integrated by the PVH and the rest of this network to control a variety of responses to metabolic stressors that have rapid (hypoglycemia) or slow onsets (eating a high calorie diet).

Complex skin modes in non-Hermitian coupled laser arrays.

From biological ecosystems to spin glasses, connectivity plays a crucial role in determining the function, dynamics, and resiliency of a network. In the realm of non-Hermitian physics, the possibility of complex and asymmetric exchange interactions ([Formula: see text]) between a network of oscillators has been theoretically shown to lead to novel behaviors like delocalization, skin effect, and bulk-boundary correspondence. An archetypical lattice exhibiting the aforementioned properties is that proposed by Hatano and Nelson in a series of papers in late 1990s.

The elusive cephalic phase insulin response: triggers, mechanisms, and functions.

The cephalic phase insulin response (CPIR) is classically defined as a head receptor-induced early release of insulin during eating that precedes a postabsorptive rise in blood glucose. Here we discuss, first, the various stimuli that elicit the CPIR and the sensory signaling pathways (sensory limb) involved; second, the efferent pathways that control the various endocrine events associated with eating (motor limb); and third, what is known about the central integrative processes linking the sensory and motor limbs. Fourth, in doing so, we identify open questions and problems with respect to the CPIR in general.

Subjective socioeconomic status is associated with risk aversion in a community-based cohort of older adults without dementia.

Attitudes towards risk impact financial decisions that are critical in older adulthood. Socioeconomic status (SES) influences an individual's level of risk aversion; however, the association of subjective SES (i.e.

Functional and neuromuscular changes induced a low-cost, muscle-computer interface for telerehabilitation: A feasibility study in chronic stroke.

Stroke is a leading cause of adult disability in the United States. High doses of repeated task-specific practice have shown promising results in restoring upper limb function in chronic stroke. However, it is currently challenging to provide such doses in clinical practice.

Characterization of BCMA Expression in Circulating Rare Single Cells of Patients with Plasma Cell Neoplasms.

B-cell maturation antigen (BCMA), a key regulator of B-cell proliferation and survival, is highly expressed in almost all cases of plasma cell neoplasms and B-lymphoproliferative malignancies. BCMA is a robust biomarker of plasma cells and a therapeutic target with substantial clinical significance. However, the expression of BCMA in circulating tumor cells of patients with hematological malignancies has not been validated for the detection of circulating plasma and B cells.
