Article Synopsis
  • A 72-year-old man experienced a 6-month decline in voluntary speech marked by sparse speech and decreased word fluency, while other language abilities remained intact, indicating dynamic aphasia.
  • Brain MRI showed left-sided white matter volume reduction in the frontal lobe, specifically affecting areas linked to speech production, and the patient's condition worsened over two years leading to complete mutism and death from aspiration pneumonia.
  • The neuropathological diagnosis was corticobasal degeneration (CBD), suggesting that early signs of CBD may manifest as dynamic aphasia, potentially due to early involvement of certain brain pathways.

Identifying the properties of the rapid eye movement (REM) sleep circuitry and its relation to diseases has been challenging due to the neuronal heterogeneity of the brainstem. Here, we show in mice that neurons in the pontine sublaterodorsal tegmentum (SubLDT) that express corticotropin-releasing hormone-binding protein (Crhbp neurons) and project to the medulla promote REM sleep. Within the medullary area receiving projections from Crhbp neurons, neurons expressing nitric oxide synthase 1 (Nos1 neurons) project to the SubLDT and promote REM sleep, suggesting a positively interacting loop between the pons and the medulla operating as a core REM sleep circuit.

Cardiovascular diseases (CVDs) a major contributor to global mortality rates, with a steadily rising prevalence observed across the world. Understanding the molecular mechanisms that underlie the signaling pathways implicated in the pathogenesis of CVDs represents a salient and advantageous avenue toward the development of precision and targeted therapeutics. A recent development in CVDs research is the discovery of long non-coding RNAs (lncRNAs), which are now understood to have crucial roles in the onset and development of several pathophysiological processes.

One of the most recognizable cases of preimplantation genetic diagnosis (PGD) is X-linked diseases. Diagnosis of fetal sex is essential for couples who are known to be at risk of some X-linked disorders. The objective of this study was to discriminate between female (XX) and male (XY) embryos by detecting sex chromosomes-specific sequences in spent culture medium and comparing these results to PGD/CGH array results.

Objective: Head and neck squamous cell carcinoma (HNSCC) with a high mortality rate is among the most common types of cancer in the world. Human epidermal growth factor receptor 2 (HER2) is expressed higher than normal level in the most HNSCC tumors, making them resistant to chemotherapy and radiotherapy. Therefore, HER2 has been introduced as a suitable target for anticancer drugs.

Multiple sclerosis (MS) is a complex autoimmune disorder that affects the central nervous system. Although the pathological mechanisms of MS have been extensively studied, its association with other autoimmune diseases, known as comorbidities, remains unclear. In this comprehensive review article, we aim to clarify the cellular and molecular relationship between MS and the incidence of organ-specific autoimmune comorbidities by summarizing former studies.

Lentinula edodes has the ability to grow and produce bioactive compounds on industrial by-products. This study aimed to produce B-glucan of cell wall Shiitake on Beechwood Sawdust (BWS) through a two-step procedure, which included fermentation and B-glucan extraction and purification. Shiitake mushrooms are cultivated by solid-state fermentation (SSF) using the Jamas method to increase the purity of B-glucan.

Introduction: Prostate cancer (PCa) is one of the most common cancers worldwide. PCa diagnosis is mostly based on solid biopsy and prostate-specific antigen (PSA), which have the disadvantages of being invasive and insensitive, respectively. Recently, the detection of microRNAs (miRNAs) in expressed prostatic secretions (EPS) has been a promising approach for PCa diagnosis.

Prostate-specific membrane antigen (PSMA) is a type II membrane glycoprotein overexpressed in a variety of tumors, especially in nearly all prostate cancers, which makes it a potentially attractive antigen for targeted cancer therapies. More importantly, PSMA, due to no shedding into circulation and efficient internalization after antibody binding, becomes a potential target for antibody-drug conjugates (ADCs), a valid and emerging paradigm of cancer treatment. Four and eight PSMA-directed ADCs have been or are currently being investigated in clinical trials (three of which failed to confirm the promising results while one is currently being evaluated in an ongoing clinical study) and preclinical studies, respectively, for the treatment of PSMA-positive solid tumors, especially prostate cancer.

Purpose: Acute ischemic stroke (AIS) is a life-threatening condition demanding prompt reperfusion to salvage brain tissue. Thrombolytic drugs, like tenecteplase (TNK), offer clot dissolution, but time constraints and contraindications limit their use. Mechanical thrombectomy (MT) revolutionized AIS treatment, especially for large vessel occlusions (LVO).

Background Acquired resistance to 5-fluorouracil (5-FU) frequently results in chemotherapy failure and disease recurrence in advanced colorectal cancer (CRC) patients. Research has demonstrated that dysregulation of long non-coding RNAs (lncRNAs) mediates the development of chemotherapy resistance in cancerous cells. The present study aims to identify key lncRNAs associated with 5-FU resistance in CRC using bioinformatic and experimental validation approaches.
