Glucocorticoid receptor suppresses GATA6-mediated RNA polymerase II pause release to modulate classical subtype identity in pancreatic cancer.

Background: Pancreatic ductal adenocarcinoma (PDAC) is a highly lethal cancer with a 5-year survival rate of 12%. It has two major molecular subtypes: classical and basal, regulated by the master transcription factors (MTFs) GATA6 and ΔNp63, respectively.

Objective: This study sought to uncover the transcriptional regulatory mechanisms controlling PDAC subtype identity.

Sustainable synthesis of benzimidazole-based Schiff base using reusable CaAlO nanophosphors catalyst: Insights into metal(II) complexes and DNA interactions.

This article presents a new and facile method for the synthesis of Schiff base compounds with a benzimidazole group using a low-cost and reusable calcium aluminate nanophosphorus catalyst (CaAlO). This approach avoids harmful solvents and reactants, supporting a more environmentally friendly synthesis process. The catalyst maintained its activity and heterogeneity over four cycles with minimal loss of efficiency.

Development of a novel modified selective medium cefixime-tellurite-phosphate-xylose-rhamnose MacConkey agar for isolation of Escherichia albertii and its evaluation with food samples.

Since cefixime and tellurite are known to inhibit most bacteria belonging to Enterobacterales, we found that addition of tellurite inhibited E. albertii growth in Luria Bertani broth but not in tryptic soy broth (TSB), and addition of phosphate and soy peptone enhanced E. albertii growth in TSB in presence of tellurite.

Targeted dual biologic therapy for erythroderma of unknown etiology guided by high-parameter peripheral blood immunophenotyping.

Erythroderma is a severe and heterogeneous inflammatory skin condition with little guidance on the approach to management in cases of unknown etiology. To guide therapeutic selection, we sought to create an immunophenotyping platform able to identify aberrant cell populations and cytokines in subtypes of erythroderma. We performed high-parameter flow cytometry on peripheral blood mononuclear cells (PBMCs) and whole blood of a patient with refractory idiopathic erythroderma, erythrodermic patients with Sézary syndrome and pityriasis rubra pilaris, and healthy controls.

Efficacy of collagen and elastin matrix in the treatment of complex lower extremity wounds.

Successful engraftment of skin grafts highly depends on the quality of the wound bed. Good quality of blood vessels near the surface is critical to support the viability of the graft. Ischemic, irradiated scar tissue, bone and tendons will not have the sufficient blood supply.

Intramuscular Cellular Nodules in a Congenital Large Plaque-Like Blue Nevus: Melanoma or Not?

Introduction: Melanoma arising in blue nevus (BN) is usually evident on histopathology. However, there are cases in the gray zone where neither morphology nor immunostains and molecular studies are conclusive.

Case Report: A 33-year-old man presented with greenish discoloration of the abdominal skin at birth.

ATM and IRAK1 orchestrate two distinct mechanisms of NF-κB activation in response to DNA damage.

DNA damage in cells induces the expression of inflammatory genes. However, the mechanism by which cells initiate an innate immune response in the presence of DNA lesions blocking transcription remains unknown. Here we find that genotoxic stresses lead to an acute activation of the transcription factor NF-κB through two distinct pathways, each triggered by different types of DNA lesions and coordinated by either ataxia-telangiectasia mutated (ATM) or IRAK1 kinases.

One-year mortality and re-admission rate by disease etiology in National Heart Failure Registry of India.

Survival outcomes of patients with heart failure (HF) based on their disease etiology are not well described. Here, we provide one-year mortality outcomes of 10850 patients with HF (mean age = 59.9 years, 31% women) in India.

Comparative evaluation of coronally advanced flap and semilunar coronally repositioned flap, using platelet-rich fibrin in Miller's Class I recession defects: A randomized clinical trial.

Background: For a periodontist, treating recession is always a proud moment and a challenging task. The current trial aimed at comparing and clinically evaluating semilunar coronally repositioned flap (SCRF) and coronally advanced flap (CAF) procedures combined with platelet-rich fibrin (PRF) in the management of Miller's Class I recession defects.

Materials And Methods: Thirty-six recession sites were randomly divided into the CAF or SCRF groups.

Automation and miniaturization of high-throughput qPCR for gene expression profiling.

Quantitative PCR (qPCR) is a technique commonly employed in laboratories and core facilities. In our previous study, we had shown the possibility to automate steps in a panel-specific gene expression workflow by pairing Mosquito HV with BioMark HD. Here we aimed to automate the full workflow and explore miniaturization capabilities.

Cardiac transplantation with increased-risk donors: Trends and clinical outcomes.

Background: Orthotopic Heart transplantation (OHT) is a definitive treatment for patients with advanced heart failure. Despite available evidence, recipients and some clinicians remain hesitant to accept organs from Increased Risk Donors (IRD). This study aims to report trends in acceptance of donors from IRD donors and long-term outcomes.

Cooperative Role of PACT and ADAR1 in Preventing Aberrant PKR Activation by Self-Derived Double-Stranded RNA.

Double-stranded RNAs (dsRNAs) produced during viral infections are recognized by the innate immune sensor protein kinase R (PKR), triggering a host translation shutoff that inhibits viral replication and propagation. Given the harmful effects of uncontrolled PKR activation, cells must tightly regulate PKR to ensure that its activation occurs only in response to viral infections, not endogenous dsRNAs. Here, we use CRISPR-Translate, a FACS-based genome-wide CRISPR-Cas9 knockout screening method that exploits translation levels as a readout and identifies PACT as a key inhibitor of PKR during viral infection.

Study on the performance of hydrophilic curing agent and environmentally friendly non-pozzolanic filler for the development of self-curing self-compacting concrete.

Self-compacting concrete (SCC) is often used when compaction is difficult, requiring special attention to the curing process. However, traditional curing methods usually fail in practice. Despite taking precise measures to control water evaporation, surface water on vertical structure elements can still be problematic.

Outcomes of Neoadjuvant Chemotherapy in Locally Advanced Oral Cancers: A Retrospective Analytical Study.

Introduction Head and neck cancers account for 30% of malignancies in India and oral squamous cell carcinoma is most common. 80% of the patients present with locally advanced disease and many of them are inoperable. In this study we documented the outcomes of neoadjuvant chemotherapy (NACT) in locally advanced oral cancer staged T4 with regards to downstaging the disease and to make the tumor more amenable for surgery with better access.

Targeting LLT1 as a potential immunotherapy option for cancer patients non-responsive to existing checkpoint therapies in multiple solid tumors.

Background: High levels of LLT1 expression have been found in several cancers, where it interacts with CD161 on NK cells to facilitate tumor immune escape. Targeting LLT1 could potentially relieve this inhibitory signal and enhance anti-tumor responses mediated through NK cells. Using the 'The Cancer Genome Atlas' (TCGA) database, we investigated the role of LLT1 in the tumor microenvironment (TME) across various cancers.

Breast cancer genomic analyses reveal genes, mutations, and signaling networks.

Breast cancer (BC) is the most commonly diagnosed cancer and the predominant cause of death in women. BC is a complex disorder, and the exploration of several types of BC omic data, highlighting genes, perturbations, signaling and cellular mechanisms, is needed. We collected mutational data from 9,555 BC samples using cBioPortal.
