Prevalence of traditional atherosclerotic risk factors in newly diagnosed colorectal and breast cancer patients.

Due to the shared risk factors between cardiovascular disease (CVD) and certain cancers such as breast cancer (BC) and colorectal cancer (CRC), our study aimed to assess the CVD risk factors among newly diagnosed patients with BC and CRC. The study utilized baseline data from the ongoing Cardiovascular Events in Breast and Colorectal Cancers (CIBC) cohort study conducted in Isfahan since 2019. Only patients who had recently been diagnosed with BC or CRC and had not undergone any treatment were included in the study.

Targeting cellular senescence in kidney diseases and aging: A focus on mesenchymal stem cells and their paracrine factors.

Cellular senescence is a phenomenon distinguished by the halting of cellular division, typically triggered by DNA injury or numerous stress-inducing factors. Cellular senescence is implicated in various pathological and physiological processes and is a hallmark of aging. The presence of accumulated senescent cells, whether transiently (acute senescence) or persistently (chronic senescence) plays a dual role in various conditions such as natural kidney aging and different kidney disorders.

Single-nucleus transcriptomics reveals disease- and pathology-specific signatures in α-synucleinopathies.

α-synucleinopathies are progressive neurodegenerative disorders characterized by intracellular aggregation of α-synuclein, yet their molecular pathogenesis remains unknow. Here, we explore cell-specific changes in gene expression across different α-synucleinopathies. We perform single-nucleus RNA sequencing on nearly 300,000 nuclei from the prefrontal cortex of individuals with idiopathic Parkinson's disease (iPD, n = 20), Parkinson's disease caused by LRRK2 mutations (LRRK2-PD, n = 7), multiple system atrophy (MSA, n = 6) and healthy controls (n = 13).

Enhancing vascular network visualization in 3D photoacoustic imaging: in vivo experiments with a vasculature filter.

Filter-based vessel enhancement algorithms facilitate the extraction of vascular networks from medical images. Traditional filter-based algorithms struggle with high noise levels in images with false vessel extraction, and a low standard deviation (σ) value may introduce gaps at the centers of wide vessels. In this paper, a robust technique with less sensitivity to parameter tuning and better noise suppression than other filter-based methods for two-dimensional and three-dimensional images is implemented.

Ethanol sclerotherapy in pediatric rectal prolapse: efficacy, complications, and influencing factors.

Introduction: Rectal prolapse is prevalent in children and the elderly, impacting quality of life significantly. Traditional surgical interventions carry risks, especially in pediatric patients. Ethanol sclerotherapy offers a less invasive alternative, inducing fibrosis and thickening of the rectal wall.

The Discovery of MORF-627, a Highly Selective Conformationally-Biased Zwitterionic Integrin αvβ6 Inhibitor for Fibrosis.

Inhibition of integrin αvβ6 is a promising approach to the treatment of fibrotic disease such as idiopathic pulmonary fibrosis. Screening a small library combining head groups that stabilize the bent-closed conformation of integrin αIIbβ3 with αv integrin binding motifs resulted in the identification of hit compounds that bind the bent-closed conformation of αvβ6. Crystal structures of these compounds bound to αvβ6 and related integrins revealed opportunities to increase potency and selectivity, and these efforts were accelerated using accurate free energy perturbation (FEP+) calculations.

Structural basis of thiamine transport and drug recognition by SLC19A3.

Thiamine (vitamin B) functions as an essential coenzyme in cells. Humans and other mammals cannot synthesise this vitamin de novo and thus have to take it up from their diet. Eventually, every cell needs to import thiamine across its plasma membrane, which is mainly mediated by the two specific thiamine transporters SLC19A2 and SLC19A3.

Phenotypic and genotypic identification of class C and D β-lactamases in clinical isolates of : a cross-sectional study.

Background And Aims: The emergence of () antibiotic resistance is an important public health problem worldwide that can negatively affect infection control. Therefore, obtaining knowledge about antibiotic resistance mechanisms is necessary for infection control policies. This study aimed to determine the frequency of class C and D β-lactamases in strains isolated from patients referred to Ardabil hospitals using phenotypic and genotypic tests.

Quick and effective approximation of in silico saturation mutagenesis experiments with first-order taylor expansion.

To understand the decision process of genomic sequence-to-function models, explainable AI algorithms determine the importance of each nucleotide in a given input sequence to the model's predictions and enable discovery of regulatory motifs for gene regulation. The most commonly applied method is saturation mutagenesis (ISM) because its per-nucleotide importance scores can be intuitively understood as the computational counterpart to saturation mutagenesis experiments. While ISM is highly interpretable, it is computationally challenging to perform for many sequences, and becomes prohibitive as the length of the input sequences and size of the model grows.

Podocyte-specific proteins in urinary extracellular vesicles of patients with IgA nephropathy: Vasorin and ceruloplasmin.

Introduction: Urinary extracellular vesicles (uEVs) can be considered biomarkers of kidney diseases. EVs derived from podocytes may reflect podocyte damage in different glomerular diseases. IgA nephropathy (IgAN) is one of the most common forms of glomerulonephritis (GN) characterized by proteinuria and hematuria.

The Synergy of Periodontic and Orthodontic Collaboration in Contemporary Oral Health Practice.

Orthodontic treatment (OT) has become a means of improving psychosocial well-being secondarily to enhanced occlusal function and can help patients obtain normal oral physiologic function, coordinated facial profiles, and healthy dentomaxillofacial development. With more adult patients undergoing OT, the need for interdisciplinary treatment and collaboration is vital to ensure periodontal health. This article highlights the importance of combined efforts between periodontics and orthodontics in adult patients with a history of periodontitis who are interested in OT.

Microheterogeneity in the Kinetics and Sex-Specific Response to Type I IFN.

The response to type I IFNs involves the rapid induction of prototypical IFN signature genes (ISGs). It is not known whether the tightly controlled ISG expression observed at the cell population level correctly represents the coherent responses of individual cells or whether it masks some heterogeneity in gene modules and/or responding cells. We performed a time-resolved single-cell analysis of the first 3 h after in vivo IFN stimulation in macrophages and CD4+ T and B lymphocytes from mice.

The Effectiveness of Transcranial Direct Current Stimulation (tDCS) and Omega-3 on Food Craving, Executive Functions, Weight, and Depressive Symptoms in Patients with Depression and Overweight: A Randomized Controlled Trial.

The most important hypothesis of this research was based on the fact that the mechanism of the effect of omega-3 on depression and obesity is formed through its accumulation in the dorsolateral prefrontal cortex (DLPFC), especially in women. Accordingly, we investigated the omega-3 intake and the concurrent stimulation of the DLPFC by tDCS and hypothesized that the synergy of these two treatments can increase the obtained effect size in patients with depression and overweight. This research was a double-blind randomized controlled trial (RCT) with a factorial design consisting of four treatment and control groups.

The correlation between ultrasonographic findings and clinical symptoms of pelvic endometriosis.

Objective: Considering the importance of endometriosis and its relatively high prevalence among women, this study sought to investigate clinical and Transrectal and transvaginal ultrasounds (TVS) findings of disease.

Methods: This descriptive-analytical study was performed based on medical records of 155 women with endometriosis admitted to Rasool-e Akram Hospital in Tehran for a TVS. All the sonography data and patients' information were collected into checklists and analyzed in SPSS-25 software (IBM).

Immunologic tumor microenvironment modulators for turning cold tumors hot.

Tumors can be classified into distinct immunophenotypes based on the presence and arrangement of cytotoxic immune cells within the tumor microenvironment (TME). Hot tumors, characterized by heightened immune activity and responsiveness to immune checkpoint inhibitors (ICIs), stand in stark contrast to cold tumors, which lack immune infiltration and remain resistant to therapy. To overcome immune evasion mechanisms employed by tumor cells, novel immunologic modulators have emerged, particularly ICIs targeting cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed cell death protein 1/programmed death-ligand 1(PD-1/PD-L1).

AIRE relies on Z-DNA to flag gene targets for thymic T cell tolerization.

AIRE is an unconventional transcription factor that enhances the expression of thousands of genes in medullary thymic epithelial cells and promotes clonal deletion or phenotypic diversion of self-reactive T cells. The biological logic of AIRE's target specificity remains largely unclear as, in contrast to many transcription factors, it does not bind to a particular DNA sequence motif. Here we implemented two orthogonal approaches to investigate AIRE's cis-regulatory mechanisms: construction of a convolutional neural network and leveraging natural genetic variation through analysis of F1 hybrid mice.
