Anesthetic effects on mitochondrial ATP-sensitive K channel.

BACKGROUND: Volatile anesthetics show an ischemic preconditioning-like cardioprotective effect, whereas intravenous anesthetics have cardioprotective effects for ischemic-reperfusion injury. Although recent evidence suggests that mitochondrial adenosine triphosphate-regulated potassium (mitoK(ATP)) channels are important in cardiac preconditioning, the effect of anesthetics on mitoK(ATP) is unexplored. Therefore, the authors tested the hypothesis that anesthetics act on the mitoK(ATP) channel and mitochondrial flavoprotein oxidation. METHODS: Myocardial cells were isolated from adult guinea p

Modelling the effects of human SUR1 R1420H variation on insulin secretory function using isogenic iPSC-derived pancreatic islets.

AIMS/HYPOTHESIS: An R1420H variation in sulfonylurea receptor 1 (SUR1), a subunit of the KATP channel, was previously identified in an Indig … total insulin] under high glucose challenge: 1.04 vs 0.56 in normal vs 1420RH SC-islets, p<0.001). Diazoxide reduced hyperinsulinaemia in SUR1 1420RH and 1420HH immature SC-islets, while tolbutamide elicited a greatly diminished or undetectable insulin secretory response from mature SUR1 1420RH SC-islets (13.2-fold increase in insulin secretion) and 1420HH …

BackgroundHirata syndrome, or Insulin Autoimmune Syndrome (IAS), is a rare condition characterized by hyperinsulinemic hypoglycemia due to autoantibodies targeting endogenous insulin. Its rarity and unique presentation make diagnosis and management challenging.ObjectiveTo analyze the clinical presentation, diagnostic methods, and management of IAS based on a single-center experience.MethodologyThis was a case series, conducted at a tertiary care center in northeast India, involving six cases diagnosed between January 2022 and April 2024. Clinical histories, including drug use and comorbidities

Association of type 1 stiff-person syndrome and insulinoma: a case report and narrative review.

INTRODUCTION: Stiff-person syndrome (SPS) is a rare neurological disorder that causes progressive muscle rigidity, gait disturbances, and functional impairment; type 1 is autoimmune, with positive anti-GAD antibodies (Ab), while type 2 is paraneoplastic and associated with antiamphiphysin Ab. CASE PRESENTATION: A 41-year-old man with a silent medical history presented with stiffness and functional impairment; after numerous rheumatological and neurological investigations, he was diagnosed with SPS, with evidence of high titer anti-GAD Ab. After treatment with benzodiazepines was started, the

Iptakalim protects against MPP+-induced degeneration of dopaminergic neurons in association with astrocyte activation.

Astrocyte activation observed in the MPTP mouse model and Parkinson's disease patients participates in the cascade of deleterious events that ultimately leads to death of dopaminergic neurons in the substantia nigra pars compacta (SNpc). The present study aimed to elucidate whether inhibiting astrocyte activation was involved in the protective effects of iptakalim (Ipt), a novel ATP-sensitive potassium channel opener, on MPP+-induced degeneration of dopaminergic neurons. The results showed that Ipt could decrease MPP+-induced TNF-alpha release and p38 MAPK activation in reactive astrocytes. Th

Endocrine paraneoplastic syndromes in lung cancer: A call for clinical vigilance (Review).

Endocrine paraneoplastic syndromes (PNS) are uncommon but clinically impactful manifestations associated with malignancies, particularly lung cancer, most notably small-cell lung cancer. These syndromes arise from ectopic hormone production by malignant cells, causing systemic effects that are independent of direct tumor invasion or metastasis. Their presentation often precedes or signals recurrence of the primary cancer, underscoring the importance of early recognition and targeted intervention. Common endocrine PNS in lung cancer include syndrome of inappropriate antidiuretic hormone secreti

Ascorbic Acid Sensitizes Colorectal Carcinoma to the Cytotoxicity of Arsenic Trioxide via Promoting Reactive Oxygen Species-Dependent Apoptosis and Pyroptosis.

Arsenic trioxide (ATO) is an effective therapeutic agent against acute promyelocytic leukemia (APL); however, its anti-tumor effect on solid tumors such as colorectal cancer (CRC) is still in debate. Ascorbic acid (AA) also produces a selective cytotoxic activity against tumor cells. Here, we exploit the potential benefit of ATO/AA combination in generating cytotoxicity to CRC cells, which may lay the groundwork for the potential combinational chemotherapy of CRCs. According to the results, we found that ATO and AA effectively inhibited the viability of human CRC cells in a synergistic manner.

Стратегии защиты от нейропии в множестве склерозов: обновление статуса и формирующиеся парадигмы.

ВВЕДЕНИЕ: MS представляет собой континуум заболеваний, в котором с момента начала и с течением времени происходит злокачественное воспаление и нейродегенерация. Недавний прогресс в недостатке патобиологии MS создает новые перспективы для новых терапевтических стратегий нейрозащиты. ОБЛАСТЬ ПРИМЕНЕНИЯ: Авторы кратко рассматривают механизмы, лежащие в основе воспаления и нейродегенерации в MS, и обсуждают нынешние и формирующиеся стратегии поощрения нейрозащиты в MS.

Paraneoplastic Endocrine Changes in Gastrointestinal Tumors: A Clinical and Mechanistic Review.

Paraneoplastic endocrine syndromes (PESs) are hormonal disturbances associated with malignancies that result from tumor-related production of hormone-like substances, immune-mediated mechanisms, or dysregulated signaling pathways. While they are well recognized in lung and neuroendocrine cancers, their relevance in gastrointestinal tumors remains less clearly defined. This narrative review synthesizes current knowledge on paraneoplastic endocrine manifestations in gastrointestinal malignancies, based on a structured search of the literature in major databases, including PubMed, Scopus, and Web

Pituitary Adenylate Cyclase-Activating Polypeptide: 30 Years in Research Spotlight and 600 Million Years in Service.

Emerging from the depths of evolution, pituitary adenylate cyclase-activating polypeptide (PACAP) and its receptors (i.e., PAC1, VPAC1, VPAC2) are present in multicellular organisms from Tunicates to humans and govern a remarkable number of physiological processes. Consequently, the clinical relevance of PACAP systems spans a multifaceted palette that includes more than 40 disorders. We aimed to present the versatility of PACAP1-38 actions with a focus on three aspects: (1) when PACAP1-38 could be a cause of a malfunction, (2) when PACAP1-38 could be the cure for a malfunction, and (3) when PA

Purinergic Signalling: Therapeutic Developments.

Purinergic signalling, i.e., the role of nucleotides as extracellular signalling molecules, was proposed in 1972. However, this concept was not well accepted until the early 1990's when receptor subtypes for purines and pyrimidines were cloned and characterised, which includes four subtypes of the P1 (adenosine) receptor, seven subtypes of P2X ion channel receptors and 8 subtypes of the P2Y G protein-coupled receptor. Early studies were largely concerned with the physiology, pharmacology and biochemistry of purinergic signalling. More recently, the focus has been on the pathophysiology and the
