Prevalence of hepatitis C virus co-infection in adults living with HIV in Mexico: a cross-sectional, seroprevalence study in a nationally representative sample.

Background: The proportion of people living with HIV (PLWHIV) co-infected with HCV in Mexico was unknown. Our aim was to estimate the seroprevalence of HCV among adults with HIV in Mexico.

Methods: Using a complex-survey design, we collected blood samples and applied structured questionnaires between May 2nd, 2019 and February 17th, 2020 in a nationally, representative sample of adults receiving care for HIV-infection in 24 randomly selected HIV-care centres in 8 socio-demographically regions in Mexico.

FOXJ3, a novel tumor suppressor in neuroblastoma.

Neuroblastoma (NB) poses a significant challenge in pediatric cancer care due to its aggressive nature and poor prognosis. While advances have been made in clinical treatments, therapy resistance remains a tough hurdle in NB treatment. While much research has focused on identifying oncogenes in NB, there has been less emphasis on understanding tumor suppressors.

Full-thickness arthroscopic rotator cuff repair demonstrates low repair failure rates and high return to sport rates in patients aged 30 years and under at 9-year follow-up: A single-center case series.

Purpose: The purpose of this study is to assess the long-term clinical complications, outcomes, and return to sport (RTS) rates in patients aged 30 or younger with a primary full-thickness arthroscopic rotator cuff repair (ARCR).

Methods: All patients who underwent a primary full-thickness ARCR at age 30 years or younger from 2003 to 2021 with a minimum of a 2-year follow-up were included. Complications, repeat surgeries, and return to sport rates were collected.

ZFAND6 promotes TRAF2-dependent mitophagy to restrain cGAS-STING signaling.

ZFAND6 is a zinc finger protein that interacts with TNF receptor-associated factor 2 (TRAF2) and polyubiquitin chains and has been linked to tumor necrosis factor (TNF) signaling. Here, we report a previously undescribed function of ZFAND6 in maintaining mitochondrial homeostasis by promoting mitophagy. Deletion of ZFAND6 in bone marrow-derived macrophages (BMDMs) upregulates reactive oxygen species (ROS) and the accumulation of damaged mitochondria due to impaired mitophagy.

CD137 agonism enhances anti-PD1 induced activation of expanded CD8 T cell clones in a neoadjuvant pancreatic cancer clinical trial.

Successful pancreatic ductal adenocarcinoma (PDAC) immunotherapy requires therapeutic combinations that induce quality T cells. Tumor microenvironment (TME) analysis following therapeutic interventions can identify response mechanisms, informing design of effective combinations. We provide a reference single-cell dataset from tumor-infiltrating leukocytes (TILs) from a human neoadjuvant clinical trial comparing the granulocyte-macrophage colony-stimulating factor (GM-CSF)-secreting allogeneic PDAC vaccine GVAX alone, in combination with anti-PD1 or with both anti-PD1 and CD137 agonist.

Proteasome inhibition induces microtubule-dependent changes in nuclear morphology.

Cancers and neurodegenerative disorders are associated with both disrupted proteostasis and altered nuclear morphology. Determining if changes in nuclear morphology contribute to pathology requires an understanding of the underlying mechanisms, which are difficult to elucidate in cells where pleiotropic effects of altering proteostasis might indirectly influence nuclear morphology. To investigate direct effects, we studied nuclei assembled in egg extract where potentially confounding effects of transcription, translation, cell cycle progression, and actin dynamics are absent.

Directed evolution of an orthogonal transcription engine for programmable gene expression in eukaryotes.

T7 RNA polymerase (RNAP) has enabled orthogonal control of gene expression and recombinant protein production across diverse prokaryotic host chassis organisms for decades. However, the absence of 5' methyl guanosine caps on T7 RNAP-derived transcripts has severely limited its utility and widespread adoption in eukaryotic systems. To address this shortcoming, we evolved a fusion enzyme combining T7 RNAP with the single subunit capping enzyme from African swine fever virus using .

Global regulators enable bacterial adaptation to a phenotypic trade-off.

Cellular fitness depends on multiple phenotypes that must be balanced during evolutionary adaptation. For instance, coordinating growth and motility is critical for microbial colonization and cancer invasiveness. In bacteria, these phenotypes are controlled by local regulators that target single operons, as well as by global regulators that impact hundreds of genes.

Light-dark shift promotes colon carcinogenesis through accelerated colon aging.

Colorectal cancer (CRC) is the third most common cancer worldwide, with rising prevalence among younger adults. Several lifestyle factors, particularly disruptions in circadian rhythms by light-dark (LD) shifts, are known to increase CRC risk. Epidemiological studies previously showed LD-shifts are associated with increased risk of CRC.

ETV2/ER71 regulates hematovascular lineage generation and vascularization through an H3K9 demethylase, KDM4A.

ETV2/ER71, an ETS (E-twenty six) transcription factor, is critical for hematopoiesis and vascular development. However, research about the molecular mechanisms behind ETV2-mediated gene transcription is limited. Herein, we demonstrate that ETV2 and KDM4A, an H3K9 demethylase, regulate hematopoietic and endothelial genes.

Yip1 interacting factor homolog B mediates the unconventional secretion of ORF8 during SARS-CoV-2 infection.

Severe cases of COVID-19 are associated with immune responses that lead to a surge in inflammatory molecules, resulting in multi-organ failure and death. This significant increase in inflammatory factors is triggered by viral proteins. Open reading frame 8 (ORF8) has received particular attention as a unique accessory protein of SARS-CoV-2.

Exosomal Galectin-3 promotes peritoneal metastases in gastric adenocarcinoma via microenvironment alterations.

Peritoneal carcinomatosis (PC) in gastric adenocarcinoma (GAC) is the most common metastatic site and leads to a short median survival. Exosomes have been shown to remodel the microenvironment, facilitating tumor metastases. However, the functional component in GAC cell-derived exosomes that remodel the landscape in the peritoneal cavity remains unclear.

Zebrafish glial-vascular interactions progressively expand over the course of brain development.

Glial-vascular interactions are critical for the formation and maintenance of brain blood vessels and the blood-brain barrier (BBB) in mammals, but their role in the zebrafish BBB remains unclear. Using three glial gene promoters-, , and (a truncated )-we explored glial-vascular development in zebrafish. Sparse labeling showed fewer glial-vascular interactions at early stages, with glial coverage and contact area increasing with age.

Mitoregulin self-associates to form likely homo-oligomeric pore-like complexes.

We and others previously found that a misannotated long noncoding RNA encodes for a conserved mitochondrial transmembrane microprotein named Mitoregulin (Mtln). Beyond an established role for Mtln in lipid metabolism, Mtln has been shown to broadly influence mitochondria, boosting respiratory efficiency and Ca retention capacity, while lowering ROS, yet the underlying mechanisms remain unresolved. Prior studies have identified possible Mtln protein interaction partners; however, a lack of consensus persists, and no claims have been made about Mtln's structure.

The canonical deep neural network as a model for human symmetry processing.

A key property of our environment is the mirror symmetry of many objects, although symmetry is an abstract global property with no definable shape template, making symmetry identification a challenge for standard template-matching algorithms. We therefore ask whether Deep Neural Networks (DNNs) trained on typical natural environmental images develop a selectivity for symmetry similar to that of the human brain. We tested a DNN trained on such typical natural images with object-free random-dot images of 1, 2, and 4 symmetry axes.

Relationships of eating behaviors with psychopathology, brain maturation and genetic risk for obesity in an adolescent cohort study.

Unhealthy eating, a risk factor for eating disorders (EDs) and obesity, often coexists with emotional and behavioral problems; however, the underlying neurobiological mechanisms are poorly understood. Analyzing data from the longitudinal IMAGEN adolescent cohort, we investigated associations between eating behaviors, genetic predispositions for high body mass index (BMI) using polygenic scores (PGSs), and trajectories (ages 14-23 years) of ED-related psychopathology and brain maturation. Clustering analyses at age 23 years ( = 996) identified 3 eating groups: restrictive, emotional/uncontrolled and healthy eaters.

The impact of task-sharing scalable mental health interventions on non-specialist providers: a scoping review.

Task-sharing approaches that train non-specialist providers (NSPs), people without specialized clinical training, are increasingly utilized to address the global mental health treatment gap. This review consolidates findings from peer reviewed articles on the impact of task-sharing mental health interventions on NSPs at the individual, family and community level. Studies that highlighted facilitators, barriers and recommendations for improving the experiences of NSPs were also included in the review.

A new airtight sampling method for sulfur hexafluoride (SF) in groundwater.

In the past 20 years, sulfur hexafluoride (SF) has been considered a highly reliable tracer for assessing modern water (< 65 yrs old) in groundwater. However, modern-air contamination may introduce complications in interpreting data obtained using current sampling methods. A new airtight methodology isolates the sample from modern ambient air; thus, returning more reproducible and reliable results when compared to two traditional (air-sensitive and non-airtight) methods.

Perspectives on the use of decellularized/devitalized and lyophilized human perinatal tissues for bone repair: Advantages and remaining challenges.

Human amniotic membrane (hAM) has been extensively used for several decades as a bioactive scaffold for regenerative medicine. In its cryopreserved form-one of the main storage formats-the presence of viable cells has often been questioned. Furthermore, there is little published evidence of the role of endogenous amniotic cells from cryopreserved hAM in tissue repair.

From Lab to Limb: Unraveling Translational Insights and Significance of Animal Models in Lower Extremity Transplantation.

The advancements in medicine throughout the twentieth century have been largely attributed to animal studies. The initial step in researching an animal disease is to establish a model closely resembling the clinical circumstances in humans. Consequently, an excellent animal model is essential for almost any experimental research.

Disparities in Clinical Outcomes Observed Within Electronic Health Record Data From a Statewide Cohort of Pulmonary Arterial Hypertension Patients.

Health disparities in patients with pulmonary arterial hypertension (PAH) have not been extensively reported in the United States. The aim of this project was to characterize the extent of demographic and socioeconomic disparities in clinical outcomes within a large, diverse PAH patient population. A retrospective, population-based study of electronic health record data from the OneFlorida Data Trust was completed.

Development of a latency model for HIV-1 subtype C and the impact of long terminal repeat element genetic variation on latency reversal.

Sub-Saharan Africa accounts for almost 70 % of people living with HIV (PLWH) worldwide, with the greatest numbers centred in South Africa where 98 % of infections are caused by subtype C (HIV-1C). However, HIV-1 subtype B (HIV-1B), prevalent in Europe and North America, has been the focus of most cure research and testing despite making up only 12 % of HIV-1 infections globally. Development of latency models for non-subtype B viruses is a necessary step to address this disproportionate focus.

Background and design of the Physical Frailty and Symptom Monitoring and Management Behaviors in Heart Failure (PRISM-HF) study: A mixed methods study.

Background: Many adults with heart failure (HF) are physically frail and have worse outcomes. While the biological profile of physical frailty in HF has been examined, the behavioral profile remains unstudied. Physical frailty may impact self-care behaviors, particularly symptom monitoring and management (SMM), which in turn results in adverse outcomes.
