Background: We assessed the diagnostic efficacy of magnetic resonance imaging (MRI) in patients with acute myocardial infarction (AMI).

Methods: In this study, 116 patients with acute myocardial infarction (AMI) underwent direct PCI intervention, admitted to our hospital between January 2018 and January 2021 were selected. Based on the presence of intramyocardial hemorrhage (IMH), they were divided into the IMH group and the non-IMH group.

Background: Subarachnoid hemorrhage (SAH) is a common acute condition in neurosurgery, with microglial function playing a crucial role in determining patient outcomes. However, the involved mechanisms are complex and demand thorough investigation. In our study, we combined transcriptomic and metabolomic approaches to identify key regulators of microglial function, offering novel insights for potential therapeutic strategies in SAH treatment.

Background: This study examines the Stress Hyperglycemia Ratio (SHR) as a predictor of mortality in acute brain injury (ABI) patients using the MIMIC-IV v3. 1 database.

Methods: In this retrospective cohort study of 2,423 ABI patients, SHR was calculated as SHR = [Admission blood glucose (mg/dL)] / [28.

Transfer technique has become an indispensable process in the development of two-dimensional materials (2DMs) and their heterostructures, as it determines the quality of the interface and the performance of the resulting devices. However, how to flexibly and conveniently fabricate two-dimensional (2D) twisted heterostructures with high-quality interfaces has always been a formidable challenge. Here, a quasi-dry transfer technique assisted by water vapor intercalation (WVI) is developed, which can be flexibly used to fabricate twisted heterostructures.

Background: The primary cause of subarachnoid hemorrhage (SAH) is the rupture of intracranial aneurysms. Over-activation of microglia following SAH is a primary driving force in early brain injury (EBI), which is a leading cause of poor outcomes. Silybin is a flavonoid compound extracted from Silybum marianum, a plant belonging to the Asteraceae family.

Background: Subarachnoid hemorrhage (SAH) remains a serious public health problem worldwide, especially in economically developed regions/countries. This study intends to thoroughly analyze the incidence, mortality, and disability-adjusted life years (DALYs) rate of SAH at the global, regional, and national levels. This study focused on the differences in SAH incidence between China and Japan from 1990 to 2019, and projected global, Chinese, and Japanese SAH incidence rates until 2030.

Purpose: This study primarily elucidating the specific mechanism of SIRT2 on neuroinflammation and microglial pyroptosis in a mouse model of SAH.

Patients And Methods: CSF were collected from 57 SAH patients and 11 healthy individuals. C57BL/6 mouse SAH model was established using prechiasmatic cistern blood injection and the in vitro hemoglobin (Hb) stimulation microglia model.

Background: Collision tumors are defined as two or more distinctly bordered, mutually invasive tumors in the same anatomical region. Characterized by low incidence and lack of specificity, they often pose a significant challenge to disease diagnosis. Among these, collision tumors in the sella region are incredibly rare.

Article Synopsis
  • The study examines how the autophagy-lysosomal pathway (ALP) is affected in neurons after subarachnoid hemorrhage (SAH), revealing that it becomes impaired.
  • TET3, a gene regulator important for autophagy, shows decreased expression following SAH, contributing to this impairment.
  • The research suggests that elevating TET3 levels could improve ALP function and that targeting miR-93-5p, which increases after SAH and suppresses TET3, may offer new therapeutic strategies for neuroprotection.

Serving as neuromorphic hardware accelerators, memristors play a crucial role in large-scale neuromorphic computing. Herein, two-terminal memristors utilizing amorphous indium-gallium-zinc oxide (a-IGZO) are fabricated through room-temperature sputtering. The electrical characteristics of these memristors are effectively modulated by varying the oxygen flow during the deposition process.

Background: Menaquinone-4(MK-4), the isoform of vitamin K2 in the brain, exerts neuroprotective effects against a variety of central nervous system disorders. This study aimed to demonstrate the anti-ferroptosis effects of MK-4 in neurons after SAH.

Methods: A subarachnoid hemorrhage (SAH) model was prepared by endovascular perforation in mice.

Article Synopsis
  • The study investigates how microglia, a type of immune cell in the brain, clear blood and maintain homeostasis after a subarachnoid hemorrhage (SAH), focusing on LC3-associated phagocytosis (LAP) and its regulation through specific gene pathways.
  • Researchers utilized an in vitro model simulating SAH to explore key signaling pathways, particularly emphasizing the P38 MAPK and DAPK1 pathways, which were linked to inhibited LAP and increased inflammation in microglia.
  • Findings revealed that the P38-DAPK1 signaling axis influences the expression of the gene BECN1, thereby affecting both the phagocytic ability and overall health of microglia in the context of SAH.

The pathological condition of insulin resistance prevents the neuroprotective effects of insulin. Numerous studies have demonstrated that insulin resistance, as an independent risk factor for ischemic stroke, accelerates the formation of thrombosis and promotes the development of atherosclerosis, both of which are major mechanisms of ischemic stroke. Additionally, insulin resistance negatively affects the prognosis of patients with ischemic stroke regardless of whether the patient has diabetes, but the mechanisms are not well studied.

Neuronal apoptosis after subarachnoid hemorrhage (SAH) is believed to play an important role in early brain injury after SAH. The energy metabolism of neuron is closely related to its survival. The transient hyperglycemia caused by insulin resistance (IR) after SAH seriously affects the prognosis of patients.

The best time window of percutaneous coronary intervention (PCI) is within 12 hours for ST-segment elevation myocardial infarction (STEMI). However, there is limited evidence about the proper time of PCI for delayed STEMI patients.From June 2014 to June 2015, a total of 268 patients receiving PCI with second-generation drug-eluting stent in a Chinese hospital after 3 days of STEMI onset were enrolled in this retrospective study, who were divided into the early group (3-14 days) and the late group (>14 days).
