Sequencing-based microbial count data analysis is a challenging task due to the presence of numerous non-biological zeros, which can impede downstream analysis. To tackle this issue, we introduce two novel approaches, PhyImpute and UniFracImpute, which leverage similar microbial samples to identify and impute non-biological zeros in microbial count data. Our proposed methods utilize the probability of non-biological zeros and phylogenetic trees to estimate sample-to-sample similarity, thus addressing this challenge.

Purpose: Stuttering epidemiology is reviewed with a primary goal of appraising methods used to identify stuttering in large populations. Secondary goals were to establish a best estimate of adult stuttering prevalence; identify data that could subgroup stuttering based upon childhood versus adult onset and covert versus over behaviour; and conduct a preliminary assessment of the degree to which stuttering features as a co-occurring diagnosis.
Methods: Systematic review followed PRISMA guidelines.

Introduction: Kidney transplantation (KT) in older age is increasingly common as more elderly patients live with end-stage renal disease. Immunosuppression (IS) after KT confers additional risk in aging patients with weakened immune systems. We hypothesized that 1-year mortality among KT recipients aged 70 y and older would be higher in those receiving induction IS with alemtuzumab lymphocyte depletion versus basiliximab interleukin-2 inhibition.

Background: Clinical gait analysis plays a pivotal role in diagnosing and treating walking impairments. Inertial measurement units (IMUs) offer a low-cost, portable, and practical alternative to traditional gait analysis equipment, making these techniques more accessible beyond specialized clinics. Previous work and algorithms developed for specific clinical populations, like in individuals with Parkinson's disease, often do not translate effectively to other groups, such as stroke survivors, who exhibit significant variability in their gait patterns.

Background: There is increasing interest in enhancing the response of the PARP inhibitor olaparib, which is currently approved for pancreatic ductal adenocarcinoma (PDAC) patients with defects in DNA damage repair associated with germline BRCA1/2 mutations. Moreover, agents that can mimic these defects in the absence of germline BRCA1/2 mutations are an area of active research in hopes of increasing the number of patients eligible for treatment with PARP inhibitors. The extent to which regorafenib, an FDA-approved tyrosine kinase inhibitor, can be used to enhance the efficacy of PARP inhibitors in PDAC cells without known BRCA1/2 mutations remains to be investigated.

Background: Aromatase inhibitors (AIs) are a cornerstone of adjuvant systemic therapy for postmenopausal patients with hormone-receptor positive (HR+) breast cancer. Although AIs decrease cancer recurrence rates and improve survival rates, approximately 50 % of patients experience arthralgia-persistent pain related to worse patient outcomes and poor AI adherence. Current medical interventions for AI-associated arthralgia have limited efficacy and side effects that restrict their use among older patients.

It is widely recognized that the glycocalyx has significant implications in regulating the self-renewal and differentiation of adult stem cells; however, its composition remains poorly understood. Here, we show that the fucose-binding Aleuria aurantia lectin (AAL) binds differentially to basal cells in the stratified epithelium of the human limbus, hair follicle epithelium, and meibomian gland duct. Using fluorescence-activated cell sorting in combination with single-cell transcriptomics, we find that most epithelial progenitor cells and melanocytes in the limbus display low AAL staining (AAL) on their cell surface, an attribute that is gradually lost in epithelial cells as they differentiate into mature corneal cells.

Regulation of gene expression during development and stress response requires the concerted action of transcription factors and chromatin-binding proteins. Because this process is cell-type specific and varies with cellular conditions, mapping of chromatin factors at individual regulatory loci is crucial for understanding cis-regulatory control. Previous methods only characterize static protein binding.

Purpose: Epidemiological research of stuttering has frequently focused on children, with a relative paucity of population level data specific to adults. Prevalence data for adults are reassessed here, including a breakdown of whether stuttering is overt or covert, and whether onset was in childhood or adulthood. The engagement of adults who stutter with stuttering communities is also estimated.

The anti-apoptotic protein myeloid cell leukemia-1 (Mcl-1) contributes to the pathophysiology of acute myeloid leukemia (AML) and certain B-cell malignancies. Tumor dependence on Mcl-1 is associated with resistance to venetoclax. Voruciclib, an oral cyclin-dependent kinase (CDK) inhibitor targeting CDK9, indirectly decreases Mcl-1 protein expression and synergizes with venetoclax in preclinical models.

For several decades, molecular motor directionality has been rationalized in terms of the free energy of molecular conformations visited before and after the motor takes a step, a so-called power stroke mechanism with analogues in macroscopic engines. Despite theoretical and experimental demonstrations of its flaws, the power stroke language is quite ingrained, and some communities still value power stroke intuition. By building a catalysis-driven motor into simulated numerical experiments, we here systematically report on how directionality responds when the motor is modified accordingly to power stroke intuition.

Summary: Spatial transcriptomics (ST) allows gene expression profiling within intact tissue samples but lacks single-cell resolution. This necessitates computational deconvolution methods to estimate the contributions of distinct cell types. This paper introduces NLSDeconv, a novel cell-type deconvolution method based on non-negative least squares, along with an accompanying Python package.

Inflammation-related DNA methylation signatures obtained in liquid biopsy, such as circulating cell-free DNA (cfDNA), may serve as promising minimally invasive biomarkers that can inform diagnosis of HCC.
Methods: Using data from 249 individuals with HIV (114 individuals with normal liver conditions, 69 with fibrosis, 30 with cirrhosis, and 36 with HCC), we constructed a cfDNA methylation-based inflammation score (inflammation-DNAm score) based on 54 CpGs previously associated with circulating C-reactive protein concentrations.
Background: Pulmonary artery stenosis, neoaortic dilatation, and neoaortic valve insufficiency are among the most frequent complications of the arterial switch operation for repair of dextro-transposition of the great arteries (d-TGA). It remains difficult to predict which patients will require great arterial reintervention.
Objective: We aimed to characterize hemodynamics within the great arteries using 4D flow MRI in patients with d-TGA after the arterial switch operation.
