Genome-wide association studies have revealed >270 loci associated with schizophrenia risk, yet these genetic factors do not seem to be sufficient to fully explain the molecular determinants behind this psychiatric condition. Epigenetic marks such as post-translational histone modifications remain largely plastic during development and adulthood, allowing a dynamic impact of environmental factors, including antipsychotic medications, on access to genes and regulatory elements. However, few studies so far have profiled cell-specific genome-wide histone modifications in postmortem brain samples from schizophrenia subjects, or the effect of antipsychotic treatment on such epigenetic marks...

Because of its potent antioxidant effects, lycopene has been used in various industries including, but not limited to, food, medical, and cosmetic industries. Yarrowia lipolytica, a non-conventional yeast species, is a promising chassis due to its natural mevalonate (MVA) pathway, abundant precursor acetyl coenzyme A content, and oleaginous properties. Several gene editing tools have been developed for Y. lipolytica along with engineering strategies for tetraterpenoid production. In this study, we engineered Y...

PURPOSE: In treating cancer, different chemotherapy regimens cause chemotherapy-induced peripheral neuropathy (CIPN). Despite recent international guidelines, a gold standard for diagnosis, treatment, and care is lacking. To identify the current clinical practice and the physicians' point of view and ideas for improvement, we evaluated CIPN care by interviewing different specialists involved. METHODS: We performed semi-structured, audio-recorded, transcribed, and coded interviews with a purposive sample of oncologists, pain specialists, and neurologists involved in CIPN patients' care...

PURPOSE: Colon cancer is a prevalent cancer globally, representing approximately 10% of all cancer cases and accounting for 10% of all cancer-related deaths. Therefore, finding new therapeutic methods with high efficiency will be very valuable. Cromolyn (C), a common anti-allergic and mast cell membrane stabilizing drug, has recently shown valuable anti-cancer effects in several studies. This study was designed to investigate the anti-cancer activity of cromolyn on colon cancer in vitro and in vivo and to determine values such as selectivity index and survival effect...

PURPOSE: To examine the distortion of the linear quadratic (LQ) model of in vitro cytogenetic dose response over an extended range of γ-ray doses by analyzing the available literature data, and to establish the dose ranges, in which the LQ dose response curve (DRC) can be most accurately fitted for biological dosimetry. MATERIALS AND METHODS: Data on yields of dicentrics (Dic) or dicentrics plus centric rings (Dic + CR) induced in vitro in human lymphocytes by acute γ-rays were extracted from 108 open sources...

BACKGROUND: Pancreatic ductal adenocarcinoma (PDAC) remains a serious threat to health, with limited effective therapeutic options, especially due to advanced stage at diagnosis and its inherent resistance to chemotherapy, making it one of the leading causes of cancer-related deaths worldwide. The lack of clear treatment directions underscores the urgent need for innovative approaches to address and manage this deadly condition. In this research, we repurpose drugs with potential anti-cancer activity using machine learning (ML)...

Vertical transmission has been described following monkeypox virus (MPXV) infection in pregnant women. The presence of MPXV has been reported in the placenta from infected women, but whether pathogens colonize placenta remains unexplored. We identify trophoblasts as a target cell for MPXV replication. In a pan-microscopy approach, we decipher the specific infectious cycle of MPXV and inner cellular structures in trophoblasts. We identified the formation of a specialized region for viral morphogenesis and replication in placental cells...

INTRODUCTION: Pharmacological stress ulcer prophylaxis (SUP) has been recommended for many years to reduce the risk of clinically significant upper gastrointestinal (GI) bleeding caused by stress ulcers (SUs). Stress-related ulcer bleeding in surgical patients significantly increases morbidity and mortality. Therefore, preventing stress-induced hemorrhage is the most appropriate measure for patients who are at increased risk. However, the inappropriate use of SUP has increased in recent years, and its use in Ethiopian surgical patients has not been well studied...

The link between inflammation and cancer is well documented and colonic inflammation caused by inflammatory bowel disease (IBD) is thought to be a high-risk factor for the development of colorectal cancer (CRC). The complex crosstalk between epithelial and inflammatory cells is thought to underlie the progression from inflammation to cancer. The present review collates and summarises recent advances in the understanding of the pathogenesis of IBD-associated CRC (IBD-CRC), including the oncogenic mechanisms of the main inflammatory signalling pathways and genetic alterations induced by oxidative stress during colonic inflammation, and discusses the crosstalk between the tumour microenvironment, intestinal flora and host immune factors during inflammatory oncogenesis in colitis-associated CRC...

MicroRNAs (miRNAs/miRs) have abnormal expression in numerous tumors and are closely related to tumor development and resistance to radiotherapy and chemotherapy. However, there are few studies assessing the role and mechanism of miRNA in chordoma. The sequencing data of three pairs of chordoma and notochord tissues from the GSE56183 dataset were analyzed in the present study. Cell proliferation was assessed in vitro using Cell Counting Kit-8. Bioinformatics analysis and the dual luciferase reporter assay were used to evaluate the regulatory relationship between miR-1224 and chromobox 3 (CBX3) in chordoma...

Coronavirus disease 2019 (COVID-19)-induced pericarditis and pericardial myocarditis are common entities; however, the development of pericardial effusion post-COVID-19 infection has only been reported in about 5% of cases. Rapid and acute progression to pericardial tamponade is uncommon, and progression to effusive constrictive pericarditis (ECP) and pericardial decompression syndrome (PDS) is an even rarer phenomenon. We describe these phenomena in this report to raise awareness and aid clinicians in the early diagnosis and management of these conditions...

This systematic review aims to compare the efficacy and safety of a novel immunotherapy with low-dose interleukin 2 (IL2) across two of the most prevalent autoimmune diseases i.e. systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). Contemporary therapeutic practices have not been able to achieve complete remission from these autoimmune disorders. In contrast, low-dose IL2 has shown promise in achieving this therapeutic goal via inducing self-tolerance in patients with autoimmune diseases; however, due to variable irregularities among autoimmune processes of variable diseases, the benefit of low-dose IL2 could not be determined among different autoimmune diseases...

Bevacizumab, an anti-vascular epidermal growth factor inhibitor, is approved for the treatment of various cancers. Hypertension, gastrointestinal perforation, bleeding manifestations, impaired wound healing, and cerebrovascular accidents are common side effects associated with the monoclonal antibody. Uncommon cutaneous reactions like exfoliative dermatitis associated with bevacizumab have been documented in the medical literature. We present an unusual case of bevacizumab-induced cutaneous lupus in a patient with metastatic colon cancer that started resolving after discontinuing chemotherapy...

The phenomenon of green urine discoloration, while rare, represents a captivating clinical puzzle that challenges the distinction between benign and pathological conditions. In this report, we present an intriguing case involving a 15-year-old trauma patient admitted following a motorcycle collision, where the ensuing unconsciousness necessitated propofol induction for intubation and sedation. Remarkably, around 48 hours post-admission, the patient displayed green urine discoloration, which resolved spontaneously within just 12 hours...

Inhaled nitric oxide (NO) has been used in pediatric and adult perioperative cardiac intensive care for over three decades. NO is a cellular signaling molecule that induces smooth muscle relaxation in the mammalian vasculature. Inhaled NO has the unique ability to exert its vasodilatory effects in the pulmonary vasculature without any hypotensive side-effects in the systemic circulation. In patients undergoing cardiac surgery, NO has been reported in numerous studies to exert beneficial effects on acutely lowering pulmonary artery pressure and reversing right ventricular dysfunction and/or failure...

Arcanobacterium haemolyticum , found as normal flora in healthy individuals, is an unusual culprit for pharyngitis and sinusitis in young adults, rarely leading to severe infections. Here, we present a singular case involving a 19-year-old immunocompetent male who experienced complications arising from A haemolyticum sinusitis, leading to orbital and intracranial sinogenic complications. The patient developed severe cerebral vasospasm with delayed cerebral ischemia, necessitating aggressive management encompassing daily catheter-directed intra-arterial infusions, surgical source control, and maximal medical therapy...

INTRODUCTION: Uveitis-glaucoma-hyphema (UGH) syndrome is an infrequent but severe complication following intraocular lens implantation, characterized by anterior chamber inflammation and elevated intraocular pressure (IOP). This report presents a rare case of late-onset UGH syndrome induced by a well-positioned 1-piece posterior capsular intraocular lens (PCIOL) with a bulb of the haptics extruding through a peripheral capsular tear in a 90-year-old female, 17 years post-cataract surgery...

BACKGROUND: Since there is no clear priority or selection principle in the guidelines for myasthenia crisis, therapeutic plasma exchange (TPE) and intravenous immunoglobulin are often administered randomly. However, it should be more prudent in taking TPE due to its higher cost and risk. Studying its early response factors is crucial for managing myasthenia crisis and can improve medical and economic benefits. METHODS: A prospective observational study was conducted, and patients classified as having "impending myasthenia crisis" or experiencing a myasthenia crisis and treated by TPE were included...

OBJECTIVE: Anticancer drugs have revolutionized tumor therapy, with cutaneous toxicities such as Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) being common immune-related adverse events. The debate over the efficacy of systemic corticosteroids in treating these conditions persists, while tumor necrosis factor (TNF)-alpha inhibitors show promise. This study aims to evaluate the effectiveness and safety of combination therapy involving the TNF-α inhibitor adalimumab for SJS/TEN induced by anticancer drugs...
