J Clin Neurosci

January 2025

Department of Neurosurgery, Fundación Universitaria de Ciencias de la Salud, Hospital de San José - Sociedad de Cirugía de Bogotá, Bogotá, D.C., Colombia; Department of Neurosurgery, Hospital Universitario Fundación Santa Fe de Bogotá, Bogotá, D.C., Colombia. Electronic address:

Background: The Endoscopic Endonasal Approach (EEA) has revolutionized the treatment landscape for optic pathway-hypothalamic gliomas (OPHGs) by providing precise visualization of the lesion neuroanatomic and minimizing brain manipulation. Despite the variable clinical trajectories of OPHGs, the optimal management neurosurgical strategy continues to be a subject of debate.

Methods: We present a case of an 8-year-old female with an OPHG who underwent EEA and performed a systematic review search in English and Spanish case reports from January 2007 (date of first reported case) to June 2024, focusing on OPHG treated with EEA.

Management of natural resources and environmental systems has often involved top-down approaches in which government agencies set and enforce regulations on extractive activities. More recently, market-driven approaches were introduced to incentivise producers to voluntarily engage in practices that align with management objectives and support regulations. For the first time, we compare government and voluntary approaches within fisheries management systems and quantify their relative influences on the sustainability status of fish populations.

Cytoprotective effects of liposomal ganglioside GM1.

J Liposome Res

January 2025

Phoenix Veterans Affairs Healthcare System, Phoenix, Arizona, USA.

Gangliosides, glycosphingolipids with one or more N-acetyl-neuraminic acid groups, play essential roles in various cellular and biological processes, among them are cell signaling, neuronal development, cell-cell recognition and the modulation of immune response. Based on their multiple biological roles, the pharmacological utilization of gangliosides for the therapy of several clinical conditions is currently widely being explored but hampered by its limited water solubility. To increase the bioavailability of poorly water-soluble therapeutic agents, pharmaceutical nanocarriers such as liposomes have been developed over the last fifty years.

Background: A recent prospective phase II study (ECOG-ACRIN E2211) demonstrated that MGMT deficiency was associated with a significant response to capecitabine and temozolomide (CAPTEM) in pancreatic neuroendocrine neoplasms (NENs); however, routine MGMT analysis in NENs was not recommended. Our study sought to demonstrate whether loss of MGMT protein expression is associated with improved overall survival (OS) in patients receiving CAPTEM for NENs from various tumor sites.

Materials And Methods: Paraffin-embedded tumor samples were evaluated by immunohistochemistry (IHC) using an MGMT monoclonal antibody.

Dentistry still faces difficulties in diagnosing oral precancer and cancer, especially when it comes to early phase changes or disease detection, evaluation, and treatment. In essence, oral lumenography is the process of identifying oral lesions using a chemiluminescent light source and a toluidine blue labeling system. Since neoplastic epithelial cells have a changed nuclear-cytoplasmic ratio, acetic acid dehydration brings out this nuclear density and gives the tissue an "acetowhite" look.

Background: Liver transplant (LT) patients face various challenges, including an increased risk of coronary artery disease (CAD) for a variety of reasons, with 70% of LT recipients having one cardiovascular event. Coronary artery bypass grafting (CABG) remains one of the most commonly performed major surgical procedures in the United States, with 20-30% of LT patients requiring a CABG. Many studies have analyzed when to perform a CABG and CAD workup pre-LT, but this population remains a problem.

We investigated the protective effect of the NF-κB inhibitor, pyrrolidine dithiocarbamate (PDTC) on cardiomyocyte injury induced by HCN1 channel overexpression, and explored the underlying mechanisms. An HCN1 overexpression vector was constructed and transfected into H9C2 cells, followed by PDTC treatment. The experiments comprised the following groups: control, control + PDTC, overexpression negative control, HCN1 overexpression (HCN1-OE), and combined HCN1-OE + PDTC groups.
