DCLK1-mediated regulation of invadopodia dynamics and matrix metalloproteinase trafficking drives invasive progression in head and neck squamous cell carcinoma.

Background: HNSCC presents a significant health challenge due to its high mortality resulting from treatment resistance and locoregional invasion into critical structures in the head and neck region. Understanding the invasion mechanisms of HNSCC has the potential to guide targeted therapies, improving patient survival. Previously, we demonstrated the involvement of doublecortin like kinase 1 (DCLK1) in regulating HNSCC cell invasion.

p.Arg636Cys: A Pathogenic Variant Identified in a Family with Several Cases of Unexpected Sudden Deaths.

: Dilated cardiomyopathy (DCM) can be an inherited condition related to premature sudden cardiac death (SCD). Pathogenic variants in some genes, like , , or , have been linked to an increased risk of SCD. Although genetic study can help to stratify the arrhythmic risk, there are no specific guidelines for carriers' management.

A precision agriculture solution for water stress estimation in Hass avocado farms in Colombia.

Agriculture 4.0 technologies continue to see low adoption among small and medium-sized farmers, primarily because these solutions often fail to account for the specific challenges of rural areas. In this work, we propose and implement a design methodology to develop a Precision Agriculture solution aimed at assisting farmers in managing water stress in Hass avocado crops.

Inferring stability and persistence in the vaginal microbiome: A stochastic model of ecological dynamics.

The interplay of stochastic and ecological processes that govern the establishment and persistence of host-associated microbial communities is not well understood. Here we illustrate the conceptual and practical advantages of fitting stochastic population dynamics models to multi-species bacterial time series data. We show how the stability properties, fluctuation regimes and persistence probabilities of human vaginal microbial communities can be better understood by explicitly accommodating three sources of variability in ecological stochastic models of multi-species abundances: 1) stochastic biotic and abiotic forces, 2) ecological feedback and 3) sampling error.

MIBiG 4.0: advancing biosynthetic gene cluster curation through global collaboration.

Specialized or secondary metabolites are small molecules of biological origin, often showing potent biological activities with applications in agriculture, engineering and medicine. Usually, the biosynthesis of these natural products is governed by sets of co-regulated and physically clustered genes known as biosynthetic gene clusters (BGCs). To share information about BGCs in a standardized and machine-readable way, the Minimum Information about a Biosynthetic Gene cluster (MIBiG) data standard and repository was initiated in 2015.

Epigenetic Study of Cohort of Monozygotic Twins With Hypertrophic Cardiomyopathy Due to MYBPC3 (Cardiac Myosin-Binding Protein C).

Background: Hypertrophic cardiomyopathy is an autosomal dominant cardiac disease. The mechanisms that determine its variable expressivity are poorly understood. Epigenetics could play a crucial role in bridging the gap between genotype and phenotype by orchestrating the interplay between the environment and the genome regulation.

Identification of host endotypes using peripheral blood transcriptomics in a prospective cohort of patients with endocarditis.

Inflammatory response to SARS-CoV 2 and other respiratory viruses.

Introduction: Lower respiratory tract infections (LRTI) remain a significant global cause of mortality and disability. Viruses constitute a substantial proportion of LRTI cases, with their pandemic potential posing a latent threat. After the SARS-CoV-2 pandemic, the resurgence of other respiratory viruses, including Influenza and Respiratory Syncytial Virus responsible for LRTI has been observed especially in susceptible populations.

Differential regulation of the proteome and phosphoproteome along the dorso-ventral axis of the early embryo.

The initially homogeneous epithelium of the early embryo differentiates into regional subpopulations with different behaviours and physical properties that are needed for morphogenesis. The factors at top of the genetic hierarchy that control these behaviours are known, but many of their targets are not. To understand how proteins work together to mediate differential cellular activities, we studied in an unbiased manner the proteomes and phosphoproteomes of the three main cell populations along the dorso-ventral axis during gastrulation using mutant embryos that represent the different populations.

Centrally administered growth hormone secretagogue receptor antagonist DLys decreases alcohol intake and preference in male mice.

Alcohol use disorder (AUD) is a highly prevalent public health problem. The ghrelin system has been identified as a potential target for therapeutic intervention for AUD. Previous work showed that systemic administration of the growth hormone secretagogue receptor (GHSR) antagonist DLys reduced alcohol intake and preference in male mice.

Mechanical Stretch Induces Senescence of Lung Epithelial Cells and Drives Fibroblast Activation by Paracrine Mechanisms.

Severe lung injury requiring mechanical ventilation may lead to secondary fibrosis. Senescence, a cell response characterized by cell cycle arrest and a shift toward a proinflammatory/profibrotic phenotype, is one of the involved mechanisms. In this study, we explore the contribution of mechanical stretch as a trigger of senescence of the respiratory epithelium and its link with fibrosis.

Long-Term Risks of Benign and Malign Complications after Endoscopic Sphincterotomy in the Management of Benign Biliopancreatic Pathology: A Cohort Study.

Background:  Endoscopic retrograde cholangiopancreatography (ERCP) is the preferred technique for treating pathologies of the bile duct. It has been suggested that this procedure, combined with sphincterotomy, may influence the subsequent development of long-term complications. The main objective of this study was to determine the long-term complications of biliopancreatic disease after ERCP and their potential association with the development of biliopancreatic neoplasms.

PCSK9 gene variations in the clinical setting of premature cardiovascular disease: A critical appraisal.

Introduction: Information about PCSK9 gene variations and its association with cardiovascular (CV) disease is controversial. We aimed to evaluate 3 reported polymorphisms in PSCK9 in a cohort of young patients with myocardial infarction with ST segment elevation (STEMI).

Methods: Retrospective study of consecutive patients with premature STEMI (2018-2023).

Predictors of poor functional outcomes in adults with type I Chiari Malformation: Clinical and surgical factors assessed with the Chicago Chiari Outcome Scale over long-term follow-up.

Background: Trigeminal schwannoma is a rare type of tumor that arises from the Schwann cells of the trigeminal nerve.

Method: We present a case of a patient with a giant V2 trigeminal schwannoma with painful swelling in the left maxilla. A complete resection using a combined open maxillectomy and endoscopic endonasal approach was performed.

Evaluation of [F]fluoroestradiol and ChRERα as a gene expression PET reporter system in rhesus monkey brain.

Positron emission tomography (PET) reporter systems are a valuable means of estimating the level of expression of a transgene in vivo. For example, the safety and efficacy of gene therapy approaches for the treatment of neurological and neuropsychiatric disorders could be enhanced via the monitoring of exogenous gene expression levels in the brain. The present study evaluated the ability of a newly developed PET reporter system [F]fluoroestradiol ([F]FES) and the estrogen receptor-based PET reporter ChRERα, to monitor expression levels of a small hairpin RNA (shRNA) designed to suppress choline acetyltransferase (ChAT) expression in rhesus monkey brain.

Midge Abundance across Years: Modeling Inter-Annual Variation for an Avian Feeder and a Candidate Vector of Hemorrhagic Diseases in Farmed Wildlife.

(1) Background: Epizootic hemorrhagic disease virus (EHDV) and bluetongue virus (BTV) are orbiviruses that cause hemorrhagic disease (HD) with significant economic and population health impacts on domestic livestock and wildlife. In the United States, white-tailed deer () are particularly susceptible to these viruses and are a frequent blood meal host for various species of biting midges (Diptera: Ceratopogonidae) that transmit orbiviruses. The species of that transmit EHDV and BTV vary between regions, and larval habitats can differ widely between vector species.

Survival analysis and gender differences in hypertrophic cardiomyopathy proband patients referred for genetic testing.

Background: Hypertrophic cardiomyopathy (HCM) is believed to have low overall mortality rate, that could be influenced by gender, particularly among probands. We aimed to evaluate the survival rates and possible gender differences in a homogeneous cohort of HCM proband patients, referred for genetic testing, from the same geographical area, without differences in medical care access nor clinical referral pathways.

Methods: we compared the mortality rates of a cohort of consecutive HCM probands referred for genetic testing (2000-2022), from a Spanish region (xxx1) with a centralized genetic testing pathway, with its control reference population by Ederer II method.

DCLK1-Mediated Regulation of Invadopodia Dynamics and Matrix Metalloproteinase Trafficking Drives Invasive Progression in Head and Neck Squamous Cell Carcinoma.

Head and neck squamous cell carcinoma (HNSCC) is a major health concern due to its high mortality from poor treatment responses and locoregional tumor invasion into life sustaining structures in the head and neck. A deeper comprehension of HNSCC invasion mechanisms holds the potential to inform targeted therapies that may enhance patient survival. We previously reported that doublecortin like kinase 1 (DCLK1) regulates invasion of HNSCC cells.

Immunoglobulin genes and severity of COVID-19.

There is tremendous interindividual and interracial variability in the outcome of SARS-CoV-2 infection, suggesting the involvement of host genetic factors. Here, we investigated whether IgG allotypes GM (γ marker) 3 and GM 17, genetic markers of IgG1, contributed to the severity of COVID-19. IgG1 plays a pivotal role in response against SARS-CoV-2 infection.
