Background & Objectives: The context, mechanism, and outcome (CMO) framework is meant to identify specific contextual factors (C) related to organizational and program structure that trigger certain mechanisms (M) involving the unique characteristics of a program, leading to specific outcomes (O). The purpose of this study was to explore the contextual underpinnings, operational processes, and resultant effects of the faculty mentorship program at AKU-SONAM. This exploration involved the context in terms of organizational culture, mechanisms examining processes such as communication between mentors and mentees, quality of relationships, the challenges encountered, and the program's adaptability to cope up while, outcomes encompassed improvements in interpersonal relationships, career advancement, and skill development.

Lysosomal stress due to the accumulation of nucleic acids (NAs) activates endosomal TLRs in macrophages. Here, we show that lysosomal RNA stress, caused by the lack of RNase T2, induces macrophage accumulation in multiple organs such as the spleen and liver through TLR13 activation by microbiota-derived ribosomal RNAs. TLR13 triggered emergency myelopoiesis, increasing the number of myeloid progenitors in the bone marrow and spleen.

An actin-binding protein, known as Calponin 3 (CNN3), modulates the remodeling of the actin cytoskeleton, a fundamental process for the maintenance of skeletal muscle homeostasis. Although the roles of CNN3 in actin remodeling have been established, its biological significance in myoblast differentiation remains largely unknown. This study investigated the functional significance of CNN3 in myogenic differentiation, along with its effects on actin remodeling and mechanosensitive signaling in C2C12 myoblasts.

Salivary gland dysfunctions are common conditions variously related to aging, inflammatory players, and any other factor able to alter their normal physiology. These conditions may significantly impact oral and systemic health, affecting the overall quality of life. Over time, numerous therapeutic strategies have been explored to regenerate, repair, or replace injured salivary glands, focusing on those molecular and cellular mechanisms able to be safely translated into a clinical landscape.

The ongoing COVID-19 pandemic has triggered extensive research, mainly focused on identifying effective therapeutic agents, specifically those targeting highly pathogenic SARS-CoV-2 variants. This study aimed to investigate the antiviral efficacy and anti-inflammatory activity of herbal extracts derived from and , using a Golden Syrian hamster model infected with Delta, a representative variant associated with severe COVID-19. Hamsters were intranasally inoculated with the SARS-CoV-2 Delta variant and orally administered either vehicle control, , or extract at a dosage of 1000 mg/kg/day.

Background: The natural killer (NK) activity of peripheral blood mononuclear cells (PBMCs) is a crucial defense against the onset and spread of cancer. Studies have shown that patients with reduced NK activity are more susceptible to cancer, and NK activity tends to decrease due to cancer-induced immune suppression. Enhancing the natural cytotoxicity of PBMCs remains a significant task in cancer research.

Natural products are ligands and in vitro inhibitors of Alzheimer's disease (AD) tau. Dihydromyricetin (DHM) bears chemical similarity to known natural product tau inhibitors. Despite having signature polyphenolic character, DHM is ostensibly hydrophobic owing to intermolecular hydrogen bonds that shield hydrophilic phenols.

Purpose: The purpose of this study was to develop a deep learning approach that restores artifact-laden optical coherence tomography (OCT) scans and predicts functional loss on the 24-2 Humphrey Visual Field (HVF) test.

Methods: This cross-sectional, retrospective study used 1674 visual field (VF)-OCT pairs from 951 eyes for training and 429 pairs from 345 eyes for testing. Peripapillary retinal nerve fiber layer (RNFL) thickness map artifacts were corrected using a generative diffusion model.

Background: Chronic inflammation is associated with different cancers, and is identified as a key pathogenic mechanism in ovarian cancer. The purpose of our study was to evaluate systemic inflammation markers, as predictive and prognostic factors, in ovarian cancer patients with initial surgical treatment.

Subjects And Methods: We performed a retrospective study on 60 ovarian cancer patients with primary cytoreduction surgery, between 2010-2018, with a follow-up period of at least one year.

Formalin-fixed paraffin-embedded tissue (FFPET), which is the most widely used pathology archive, usually has low-quality DNA and RNA due to extensive nucleic acid crosslinking. RNA fluorescence in situ hybridization (RNA-FISH) has been increasingly utilized in research and clinical settings to diagnose disease pathology. In this study, the effect of RNA degradation over archival time on RNA-FISH signals in FFPET and fresh frozen tissue (FFT) was systematically assessed.

Rubisco is the primary CO-fixing enzyme of the biosphere, yet it has slow kinetics. The roles of evolution and chemical mechanism in constraining its biochemical function remain debated. Engineering efforts aimed at adjusting the biochemical parameters of rubisco have largely failed, although recent results indicate that the functional potential of rubisco has a wider scope than previously known.

Implantable multifunctional probes have transformed neuroscience research, offering access to multifaceted brain activity that was previously unattainable. Typically, simultaneous access to both optical and electrical signals requires separate probes, while their integration into a single device can result in the emergence of photogenerated electrical artifacts, affecting the quality of high-frequency neural recordings. Among the nontrivial strategies aimed at the realization of an implantable multifunctional interface, the integration of optical and electrical capabilities on a single, minimally invasive, tapered optical fiber probe has been recently demonstrated using fibertrodes.

The molecular basis of Human FN3K mediated phosphorylation of glycated substrates.

Nat Commun

January 2025

Cold Spring Harbor Laboratory, One Bungtown Road, Cold Spring Harbor, New York, 11724, USA.

Glycation, a non-enzymatic post-translational modification occurring on proteins, can be actively reversed via site-specific phosphorylation of the fructose-lysine moiety by FN3K kinase, to impact the cellular function of the target protein. A regulatory axis between FN3K and glycated protein targets has been associated with conditions like diabetes and cancer. However, the molecular basis of this relationship has not been explored so far.

Biogenesis of human telomerase requires its RNA subunit (hTR) to fold into a multi-domain architecture that includes the template-pseudoknot (t/PK) and the three-way junction (CR4/5). These hTR domains bind the telomerase reverse transcriptase (hTERT) protein and are essential for telomerase activity. Here, we probe hTR structure in living cells using dimethyl sulfate mutational profiling with sequencing (DMS-MaPseq) and ensemble deconvolution analysis.

Microtubules (MTs) are intrinsically dynamic polymers. In neurons, staggered individual microtubules form stable, polarized acentrosomal MT arrays spanning the axon and dendrite to support long-distance intracellular transport. How the stability and polarity of these arrays are maintained when individual MTs remain highly dynamic is still an open question.
