Multifaceted Role of Specialized Neuropeptide-Intensive Neurons on the Selective Vulnerability to Alzheimer's Disease in the Human Brain.

Regarding Alzheimer's disease (AD), specific neuronal populations and brain regions exhibit selective vulnerability. Understanding the basis of this selective neuronal and regional vulnerability is essential to elucidate the molecular mechanisms underlying AD pathology. However, progress in this area is currently hindered by the incomplete understanding of the intricate functional and spatial diversity of neuronal subtypes in the human brain.

QuICSeedR: An R package for analyzing fluorophore-assisted seed amplification assay data.

Motivation: Fluorophore-assisted seed amplification assays (F-SAAs), such as real-time quaking-induced conversion (RT-QuIC) and fluorophore-assisted protein misfolding cyclic amplification (F-PMCA), have become indispensable tools for studying protein misfolding in neurodegenerative diseases. However, analyzing data generated by these techniques often requires complex and time-consuming manual processes. Additionally, the lack of standardization in F-SAA data analysis presents a significant challenge to the interpretation and reproducibility of F-SAA results across different laboratories and studies.

Preoperative factors predicting outcomes in patients with suspected perihilar cholangiocarcinoma referred for curative resection- a single-center 10-year experience.

Purpose: Perihilar cholangiocarcinoma (pCCA) is a rare malignancy requiring resection of extrahepatic bile ducts with or without hepatectomy. Prognostic models for post-operative outcomes in pCCA are unusable in pre-operative decision-making as most are based on post-operative variables. Additionally, no pre-operative models include futile laparotomy or benign hilar stenosis (BHS) as possible outcomes.

Evaluation of RT-QuIC Diagnostic Performance for Chronic Wasting Disease Detection Using Elk (Cervus canadensis) Ear Punches.

Sensitive and specific antemortem diagnostic tests are a prerequisite for effective management of chronic wasting disease (CWD). Paired with readily accessible samples that accurately reflect CWD status, the real-time quaking-induced conversion (RT-QuIC) assay has the potential to enable more effective CWD surveillance and interventions. We evaluated the feasibility of RT-QuIC as a CWD diagnostic test using 6-mm ear tissue biopsies from elk (Cervus canadensis).

Free, prior, and informed consent, local officials, and changing biodiversity governance in Hin Nam No, Laos.

Free, prior, and informed consent (FPIC) is now a globally established norm and is a condition of equitable engagement with Indigenous peoples and local communities in biodiversity conservation. However, implementation is frequently questioned in terms of its efficacy in top-down-driven governance contexts. Local officials represent core voices often absent from mainstream discourse.

Postoperative Exercise Training in Patients with Colorectal Liver Metastases A Randomized Controlled Trial.

Background: Postoperative morbidity can reduce quality of life, physical performance, and tolerability of postoperative chemotherapy in patients with colorectal liver metastases (CRLM). Exercise can improve these outcomes in some cancer populations. However, it remains unknown whether exercise can be delivered in the early postoperative period following surgery for CRLM without increasing the risk of harms.

Single-cell analysis of osmoregulation reveals heterogeneity of aquaporin 4 functionality in human astrocytes.

The water channel aquaporin 4 (AQP4) contributes to water flow and waste removal across the blood-brain barrier and its levels, organization and localization are perturbed in various neurological diseases, including Alzheimer's Disease. This renders AQP4 a potentially valuable therapeutic target. However, most functional assays aimed at identifying modulators of AQP4 function are performed with primary rodent cells and do not consider inter-cellular variations in AQP4 abundance and presentation.

Short-Term Surgical Outcomes After Robotic Liver Surgery: A Propensity-Score Matched Analysis With Conventional Open Liver Surgery at a High-Volume Centre in Denmark.

Background: The aim of this study was to investigate the perioperative outcomes of robotic liver surgery (RLS) and Open liver surgery (OLS) in a centre with a high number of operations.

Prognosis related to treatment plan in patients with biliary tract cancer: A nationwide database study.

Background: Biliary tract cancer (BTC) is a malignancy characterized by a low 5-year survival rate (<20 %). Clinical aspects such as tumor resectability, Eastern Cooperative Oncology Group performance status score (ECOG-PS), and molecular profiling are used to determine the treatment for these patients. Diagnosis and treatment are typically established by a multidisciplinary team (MDT).

Screening participants with inflammatory bowel disease or high colorectal cancer risk in Denmark: a cohort study.

Individuals with inflammatory bowel disease (IBC) and high-risk individuals are advised to discuss participation with their doctor and not to participate in colorectal cancer (CRC) screening. Yet a substantial proportion still participate in the Danish faecal immunochemical test (FIT) screening and have a higher positive FIT rate than the average-risk population. We estimated the risk of false-positive screening among individuals with inflammatory bowel disease and high-risk individuals to improve recommendations regarding screening participation.

Inter-laboratory comparison of real-time quaking-induced conversion (RT-QuIC) for the detection of chronic wasting disease prions in white-tailed deer retropharyngeal lymph nodes.

The rapid geographic spread of chronic wasting disease (CWD) in white-tailed deer (WTD; ) increases the need for the development and validation of new detection tests. Real-time quaking-induced conversion (RT-QuIC) has emerged as a sensitive tool for CWD prion detection, but federal approval in the United States has been challenged by practical constraints on validation and uncertainty surrounding RT-QuIC robustness between laboratories. To evaluate the effect of inter-laboratory variation on CWD prion detection using RT-QuIC, we conducted a multi-institution comparison on a shared anonymized sample set.

Association of Lipopolysaccharide-Type Endotoxins with Retinal Neurodegeneration: The Alienor Study.

Purpose: Lipopolysaccharide (LPS)-type endotoxins are naturally found in the gut microbiota and there is emerging evidence linking gut microbiota and neuroinflammation leading to retinal neurodegeneration. Thinning of the retinal nerve fiber layer (RNFL) is a biomarker of retinal neurodegeneration, and a hallmark of glaucoma, the second leading cause of blindness worldwide. We assessed the association of a blood biomarker of LPS with peripapillary RNFL thickness (RNFLT) and its longitudinal evolution up to 11 years.

Single-domain antibodies and aptamers drive new opportunities for neurodegenerative disease research.

Neurodegenerative diseases (NDs) in mammals, such as Alzheimer's disease (AD), Parkinson's disease (PD), and transmissible spongiform encephalopathies (TSEs), are characterized by the accumulation of misfolded proteins in the central nervous system (CNS). Despite the presence of these pathogenic proteins, the immune response in affected individuals remains notably muted. Traditional immunological strategies, particularly those reliant on monoclonal antibodies (mAbs), face challenges related to tissue penetration, blood-brain barrier (BBB) crossing, and maintaining protein stability.

MSKI reduction strategies: evidence-based interventions to reduce musculoskeletal injuries in military service members.

Musculoskeletal injuries (MSKI) are one of the biggest challenges for military services globally, contributing to substantial financial burdens and lost training and working days. Effective evidence-based intervention strategies are essential to reduce MSKI incidence, and research has shown the positive effect of both nutritional interventions and physical training (PT) interventions on reducing MSKI incidence. Levels of vitamin D metabolites have been associated with MSKI and bone stress fracture risk, while calcium and vitamin D supplementation has been shown to reduce the incidence of stress fractures during military training.

Rapid and sensitive determination of residual prion infectivity from prion-decontaminated surfaces.

Prion diseases are untreatable fatal transmissible neurodegenerative diseases that affect a wide range of mammals, including humans, and are caused by PrP, the infectious self-templating conformation of the host-encoded protein, PrP. Prion diseases can be transmitted via surfaces (e.g.
