Reduced GATA3 expression during breast cancer progression: A potential anchor for pulmonary metastatic deposition.

Estrogen receptor (ER) is a direct and reciprocal target gene for GATA3. Previous studies have shown that higher GATA3 expression in primary breast cancer (BC) is associated with a reduced probability of developing lung metastasis when compared to those with metastatic recurrence to other organs. Further, GATA3 downregulates several genes promoting BC lung metastasis and upregulates genes encoding known inhibitors of lung metastasis.

Potentialities and critical issues of liquid biopsy in clinical practice: An umbrella review.

Background: Liquid biopsy (LB) is a laboratory test performed on a fluid sample aiming at analyzing molecular data derived from circulating cells and related entities, or from nucleic acids. This umbrella review aims to map and evaluate the evidence supporting the use of LB in medicine across different medical specialities and conditions.

Methods: We searched three repositories from database inception up to October 1, 2023 and we included meta-analyses of observational studies reporting data on the use of LB, compared to gold standard, and its accuracy (area under the curve, AUC).

Peptide-based PET/CT imaging visualizes PD-L1-driven radioresistance in glioblastoma.

Radioresistance remains a great challenge for radiotherapy in the treatment of glioblastoma (GBM). PD-L1 expression is a key contributor to radioresistance and immune escape in GBM. The lack of effective methods to monitor the change of PD-L1 during radiotherapy in patients limits timely intervention and management of the resistance.

Protocol for mitochondrial variant enrichment from single-cell RNA sequencing using MAESTER.

Single-cell RNA sequencing (scRNA-seq) enables detailed characterization of cell states but often lacks insights into tissue clonal structures. Here, we present a protocol to probe cell states and clonal information simultaneously by enriching mitochondrial DNA (mtDNA) variants from 3'-barcoded full-length cDNA. We describe steps for input library preparation, mtDNA enrichment, PCR product cleanup, and paired-end sequencing.

Opposing roles of p38α-mediated phosphorylation and PRMT1-mediated arginine methylation in driving TDP-43 proteinopathy.

Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disorder typically characterized by insoluble inclusions of hyperphosphorylated TDP-43. The mechanisms underlying toxic TDP-43 accumulation are not understood. Persistent activation of p38 mitogen-activated protein kinase (MAPK) is implicated in ALS.

Effects of preferred music on internal load in adult recreational athletes: a systematic review and meta-analysis.

Introduction: When exercising to preferred music (PM), participants found more satisfaction and less typical exercise-related fatigue, which made it easier and more enjoyable to maintain the physical activity (PA) until the exercise goals were achieved. The purpose of this review and meta-analysis was to determine whether changes on internal training load in adult recreational athletes were modified by listening to PM and non-preferred music (NPM), during different PA.

Evidence Acquisition: A music-focused search was performed on the Google Scholar, PubMed, and Web of Science databases to identify relevant articles to this topic published after 2000 to investigate the effects of PM on psychophysiological responses to PA.

Pediatric Dialysis: Ethical Dilemmas Faced by Pediatric Intensive Care Nurses.

Whether pediatric dialysis is morally obligatory is an ethical issue. The study's aim was to understand neonatal and pediatric intensive care unit (ICU) nurses' beliefs regarding the ethical use of pediatric dialysis. A single center study was conducted using theoretical and case-based surveys.

Single cell derived multicellular meristem: insights into male-to-hermaphrodite conversion and de novo meristem formation in ceratopteris.

Land plants alternate between asexual sporophytes and sexual gametophytes. Unlike seed plants, ferns develop free-living gametophytes. Gametophytes of the model fern Ceratopteris exhibit two sex types: hermaphrodites with pluripotent meristems and males lacking meristems.

Achieving advanced hydrogen evolution under large current density using an amorphous/crystalline core-shell electrocatalyst of a-NiCoP/CoP.

Non-precious transition metal-based electrocatalysts with high activities are promising candidates for substituting Pt- or Ru-based electrocatalysts in hydrogen evolution. In this study, we propose core-shell engineering to combine the amorphous NiCoP and crystalline CoP (a-NiCoP/CoP@NF), which requires an ultra-low overpotential of only 26 mV to achieve the benchmark current density of 10 mA cm. Furthermore, it achieves an industrial-level hydrogen evolution current density of 500 mA cm with excellent stability.

Vaccination against SARS-CoV-2 provides low-level cross-protection against common cold coronaviruses in mouse and non-human primate animal models.

The common cold coronaviruses are a source of ongoing morbidity and mortality particularly among elderly and immunocompromised individuals. While cross-reactive immune responses against multiple coronaviruses have been described following severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and vaccination, it remains unclear if these confer any degree of cross-protection against the common cold coronaviruses. A recombinant fowl adenovirus vaccine expressing the SARS-CoV-2 spike protein (FAdV-9-S19) was generated, and protection from SARS-CoV-2 challenge was shown in K18-hACE2 mice.

Resistance mutations that distinguish HIV-1 envelopes with discordant VRC01 phenotypes from multi-lineage infections in the HVTN703/HPTN081 trial: implications for cross-resistance.

The Antibody Mediated Prevention (AMP) trials showed that passively infused VRC01, a broadly neutralizing antibody (bNAb) targeting the CD4 binding site (CD4bs) on the HIV-1 envelope protein (Env), protected against neutralization-sensitive viruses. We identified six individuals from the VRC01 treatment arm with multi-lineage breakthrough HIV-1 infections from HVTN703, where one variant was sensitive to VRC01 (IC < 25 ug/mL) but another was resistant. By comparing Env sequences of resistant and sensitive clones from each participant, we identified sites predicted to affect VRC01 neutralization and assessed the effect of their reversion in the VRC01-resistant clone on neutralization sensitivity.

Evaluating the clinical utility of , and bronchoalveolar PCRs for the diagnosis of invasive pulmonary infections in patients with hematological malignancies.

Invasive pulmonary infections are a significant cause of morbidity and mortality in patients with hematological malignancies and hematopoietic stem cell transplantation (HCT) recipients. A delay in identifying a causative agent may result in late initiation of appropriate treatment and adverse clinical outcomes. We examine the diagnostic utility of PCR-based assays in evaluating invasive pulmonary infections from bronchoalveolar lavage (BAL).

Rapid visual detection of hepatitis E virus combining reverse transcription recombinase-aided amplification with lateral flow dipstick and real-time fluorescence.

Unlabelled: Hepatitis E virus (HEV) is a globally prevalent zoonotic pathogen that is primarily spread through the fecal-oral route, such as by consuming undercooked or contaminated pork. HEV infection leads to an estimated 3.3 million symptomatic cases of viral hepatitis and 70,000 deaths in human populations each year.

colonization is not mediated by bile salts and utilizes Stickland fermentation of proline in an model.

Treatment with antibiotics is a major risk factor for infection, likely due to depletion of the gastrointestinal microbiota. Two microbiota-mediated mechanisms thought to limit colonization include the conversion of conjugated primary bile salts into secondary bile salts toxic to growth and competition between the microbiota and for limiting nutrients. Using a continuous flow model that simulates the nutrient conditions of the distal colon, we investigated how treatment with 6 clinically used antibiotics influenced susceptibility to infection in 12 different microbial communities cultivated from healthy individuals.

Multiple sclerosis and infection: history, EBV, and the search for mechanism.

SUMMARYInfection has long been hypothesized as the cause of multiple sclerosis (MS), and recent evidence for Epstein-Barr virus (EBV) as the trigger of MS is clear and compelling. This clarity contrasts with yet uncertain viral mechanisms and their relation to MS neuroinflammation and demyelination. As long as this disparity persists, it will invigorate virologists, molecular biologists, immunologists, and clinicians to ascertain how EBV potentiates MS onset, and possibly the disease's chronic activity and progression.

Temporal dynamics of airborne fungi in Swedish forest nurseries.

In Sweden, reforestation of managed forests relies predominantly on planting nursery-produced tree seedlings. However, the intense production using containerized cultivation systems (e.g.

Adaptation of clinical bacteriology techniques for remote polar research.

Unlabelled: Remote polar regions offer unique opportunities and significant challenges for antimicrobial resistance research in a near-pristine environment. While core microbiology techniques continue to have an important role in supporting environmental research, the severe cold climate presents considerable challenges to laboratory research. We explore adaptations required for core bacteriology investigations in polar regions on an unsupported remote expedition c.

Multiplexed Molecular Endophenotypes Help Identify Hub Genes in Non-Small Cell Lung Cancer: Unlocking Next-Generation Cancer Phenomics.

Next-generation cancer phenomics by deployment of multiple molecular endophenotypes coupled with high-throughput analyses of gene expression offer veritable opportunities for triangulation of discovery findings in non-small cell lung cancer (NSCLC) research. This study reports differentially expressed genes in NSCLC using publicly available datasets (GSE18842 and GSE229253), uncovering 130 common genes that may potentially represent crucial molecular signatures of NSCLC. Additionally, network analyses by GeneMANIA and STRING revealed significant coexpression and interaction patterns among these genes, with four notable hub genes-, , and -identified as pivotal in NSCLC progression.

Antagonisation of Prokineticin Receptor-2 Attenuates Preeclampsia Symptoms.

Preeclampsia (PE) is the most threatening pathology of human pregnancy. Placenta from PE patients releases harmful factors that contribute to the exacerbation of the disease. Among these factors is the prokineticin1 (PROK1) and its receptor, PROKR2 that we identified as a mediators of PE.

Tinagl1 restores tamoxifen sensitivity and blocks fibronectin-induced EMT by simultaneously blocking the EGFR and β1-integrin/FAK signaling pathways in tamoxifen-resistant breast cancer cells.

Tamoxifen (TAM) is employed to treat premenopausal ER-positive breast cancer patients, but TAM resistance is the main reason affecting its efficacy. Thus, addressing TAM resistance is crucial for improving therapeutic outcomes. This study explored the potential role of Tinagl1, a secreted extracellular matrix protein, whose expression is compromised in TAM-resistant MCF-7 breast cancer cells (MCF-7R).

Utilization of the QuPath open-source software platform for analysis of mammalian spermatogenesis.

The adult mammalian testis is filled with seminiferous tubules, which contain somatic Sertoli cells along with germ cells undergoing all phases of spermatogenesis. During spermatogenesis in postnatal mice, male germ cells undergo at least 17 different nomenclature changes as they proceed through mitosis as spermatogonia (=8), meiosis as spermatocytes (=6), and spermiogenesis as spermatids (=3) [1-6]. Adding to this complexity, combinations of germ cells at each of these stages of development are clumped together along the length of the seminiferous tubules.

Development and Validation of a Novel Model to Discriminate Idiosyncratic Drug-Induced Liver Injury and Autoimmune Hepatitis.

Background And Aim: Discriminating between idiosyncratic drug-induced liver injury (DILI) and autoimmune hepatitis (AIH) is critical yet challenging. We aim to develop and validate a machine learning (ML)-based model to aid in this differentiation.

Methods: This multicenter cohort study utilised a development set from Beijing Friendship Hospital, with retrospective and prospective validation sets from 10 tertiary hospitals across various regions of China spanning January 2009 to May 2023.

Ankle-foot orthoses for improving walking in adults with calf muscle weakness due to neuromuscular disorders.

Background: Calf muscle weakness is a common symptom in slowly progressive neuromuscular disorders that lead to walking problems like instability and increased walking effort. The mainstay of treatment to improve walking in this population is the provision of ankle-foot-orthoses (AFOs). Since we are not aware of an up-to-date and complete overview of the effects of AFOs used for calf muscle weakness in slowly progressive neuromuscular disorders, we reviewed the evidence for the effectiveness of AFOs to improve walking in this patient group, in order to support clinical decision-making.
