Zim4rv: an R package to modeling zero-inflated count phenotype on regional-based rare variants.

BMC Bioinformatics

January 2025

Centre for Quantitative Medicine, Duke-NUS Medical School, National University of Singapore, Singapore, Singapore.

Background: With the advance of next-generation sequencing, various gene-based rare variant association tests have been developed, particularly for binary and continuous phenotypes. In contrast, fewer methods are available for traits not following binomial or normal distributions. To address this, we previously proposed a set of burden- and kernel-based rare variant tests for count data following zero-inflated Poisson (ZIP) distributions, referred to as ZIP-b and ZIP-k tests.

One size does not fit all: revising traditional paradigms for assessing accuracy of QSAR models used for virtual screening.

Traditional best practices for quantitative structure activity relationship (QSAR) modeling recommend dataset balancing and balanced accuracy (BA) as the key desired objective of model development. This study explores the value of the conventional norms in the context of using QSAR models for virtual screening of modern large and ultra-large chemical libraries. For this increasingly common task, we now recommend the use of models with the highest positive predictive value (PPV) built on imbalanced training sets as preferred virtual screening tools.

Background: Fast-acting Sub-perception Therapy (FAST) is a novel spinal cord stimulation (SCS) modality delivering paresthesia-free pain relief. Our study evaluated the longer-term, real-world impact of FAST on chronic pain.

Research Design And Methods: As part of a multicenter, real-world, consecutive case series, we retrospectively identified patients who used FAST-SCS and analyzed their data.

The current study investigated the relationship between adverse childhood experiences (ACEs), post-traumatic stress disorder (PTSD) symptoms, within-network resting-state functional connectivity (rs-FC), and alcohol use during adolescence using functional magnetic resonance imaging (fMRI) data from the National Consortium on Alcohol and Neurodevelopment in Adolescence study (NCANDA;  = 687). Significant rs-FC differences emerged that linked participant ACEs, PTSD symptoms, and alcohol use problems. Participants with ACEs compared to those without had diminished rs-FC within the default mode, salience, and medial frontoparietal networks ( ≤ 0.

This study explored whether baseline autonomous motivation (AM), controlled motivation (CM), and relative autonomy index (RAI) scores predicted 12-month weight in a three-arm randomized controlled trial of internet weight loss programs in primary care. It also evaluated perceived accountability to a primary care provider for weight loss as a moderator and study engagement (operationalized as weeks logged into the study website) as a mediator of these relationships. Participants with complete data for all model variables ( = 428) were included.

Tamoxifen is the mainstay treatment for estrogen-positive breast cancer for over half a century. However, a significant proportion of patients experience disease recurrence due to treatment failure attributed to various factors, including disease pathology, genetics, and drug metabolism. Alam et al.

Childhood experiences shape later parenting behaviors; however, few studies have examined the mechanisms that explain how parenting is transmitted across generations. The present study examined direct and indirect effects of mothers' remembered emotionally responsive parenting in childhood on maternal sensitivity to infant distress via parenting-related emotion, physiology, and cognition. Participants included 299 mothers ( = 29.

Objective: Drinking intention is a predictor of heavy-drinking episodes and could serve as a real-time target for preventive interventions. However, the association is inconsistent and relatively weak. Considering the affective context when intentions are formed might improve results by revealing conditions in which intention-behavior links are strongest and the predictive power of intentions is greatest.

Unusual Phospholipids from Linked to Depression.

J Am Chem Soc

Department of Biological Chemistry and Molecular Pharmacology, Harvard Medical School and Blavatnik Institute, Boston, Massachusetts 02115, United States.

A multifactorial association study detected a probable causal connection between the prevalence of in the gut microbiome and the incidence of major depressive disorder (MDD) in the human host. A bioassay-guided fractionation approach identified bacterially produced metabolites that induced pro-inflammatory immune responses. The metabolites are unusual phospholipids that resemble conventional cardiolipins, in which diethanolamine (DEA) replaces the central glycerol.

A new series of 222 adelite-type Co(GeO)(OH) ( = La-Sm) single crystals were grown by a high-temperature, high-pressure hydrothermal method (650 °C and 100 MPa). Single-crystal diffraction refinements yielded chiral one-dimensional (1D) chains of Co along the axis with an average 2.98 Å separation between Co centers in the [CoO(OH)] ribbon chains.

Ligand-functionalized InP-based quantum dots (QDs) have been developed as an innovative class of nontoxic photosensitizer suitable for antimicrobial applications, aimed at reducing or preventing pathogen transmission from one host to another via high contact surfaces. A hot injection method followed by functionalization via ligand exchange with 9-anthracene carboxylic acid (ACA) yielded the desired core/shell InP/ZnSe/ZnS QDs. Transmission electron microscopy (TEM) revealed these QDs to be uniform in size (∼3.

Metabolomics provides powerful tools that can inform about heterogeneity in disease and response to treatments. In this exploratory study, we employed an electrochemistry-based targeted metabolomics platform to assess the metabolic effects of three randomly-assigned treatments: escitalopram, duloxetine, and Cognitive-Behavioral Therapy (CBT) in 163 treatment-naïve outpatients with major depressive disorder. Serum samples from baseline and 12 weeks post-treatment were analyzed using targeted liquid chromatography-electrochemistry for metabolites related to tryptophan, tyrosine metabolism and related pathways.

Background Context: There are a number of risk factors- from biological, psychological, and social domains- for non-specific chronic low back pain (cLBP). Many cLBP treatments target risk factors on the assumption that the targeted factor is not just associated with cLBP but is also a cause (i.e, a causal risk factor).

Asking participants to Think Aloud is a common method for studying conscious experience, but it remains unclear whether this approach alters thought qualities-such as meta-awareness, rate of topic shifts, or the content of thoughts in task-absent conditions. To investigate this, we conducted two studies comparing thinking aloud to thinking silently. In Study 1, 111 participants alternated between 15-minute intervals of verbalizing and silently reflecting on their stream of consciousness in a counterbalanced design.
