Background: Ischemic stroke (IS) caused by middle cerebral artery (MCA) disease is the most common type of IS caused by intracranial artery disease in the Chinese population. Hypertension and diabetes mellitus are the common risk factors of cerebral small vessel disease and large artery atherosclerosis (LAA). However, little is known about whether hypertension and diabetes mellitus had different correlations with the small artery occlusion (SAO) and LAA etiology of MCA disease. Therefore, our aim was to identify the predictors of the etiology of MCA disease.
Methods: We consecutively enrolled 967 patients with noncardiogenic IS in unilateral MCA territory. Vascular risk factors and the clinical-radiologic features of IS were analyzed. The etiology of IS were classified as SAO or LAA according to the Stop Stroke Study Trial of Org 10172 in Acute Stroke Treatment classification criteria. Multivariable logistic regression was used to identify the differences in the predictors between SAO and LAA etiology of MCA disease.
Results: Multivariable logistic regression identified male and hypertension as the predictors of the SAO etiology of MCA disease, however diabetes mellitus, repeated transient ischemic attack before the stroke, gaze palsy, aphasia, headache at admission, and disability at discharge as the predictors of the LAA etiology of MCA disease.
Conclusion: Hypertension and diabetes mellitus are related with the different etiology of MCA disease.

Background: Tyrosine kinase inhibitors (TKIs) improve prognosis in chronic myeloid leukemia (CML). Nilotinib and ponatinib, second- and third-generation TKIs, respectively, have been reported to cause adverse vascular occlusive events such as myocardial infarction and peripheral arterial disease. However, little is known about the risk of cerebral infarction associated with severe cerebrovascular stenosis, which is a late complication of TKIs.

Article Synopsis
- The study aimed to analyze the characteristics and treatment of patients hospitalized with severe odontogenic infections (SOI) at a Danish hospital from 2012 to 2019.
- A total of 384 patients were reviewed, revealing that the most common causes of infection were apical periodontitis and tooth extractions, with many receiving inadequate treatment before hospitalization.
- The findings suggest that better prehospital care from dentists is needed, focusing on addressing the infection's origin and improving antibiotic use.
Comparative Karyotype Analysis of Lycoris aurea Herb Populations Using Fluorochrome Banding and 45S and 5S rDNA-FISH.

To understand karyotype variation in eight populations, detailed karyotypes were meticulously established using chromosomal measurements, fluorescence bands, and rDNA FISH signals. The number of 45S rDNA sites varies from one to five pairs per population, with the most common number per karyotype being four pairs. The 45S rDNA locus is predominantly located in the short arms and terminal regions of chromosomes, while the 5S rDNA locus is found mainly in the short arm and the terminal or proximal regions.

A previously healthy middle-aged man in his 40s with a history of red scorpion envenomation presented to the emergency department for the management of an acute stroke syndrome, involving the left middle cerebral artery (MCA) territory, that developed 12 hours after the scorpion sting. He presented to the hospital 15 hours following the stroke. The activation of the autonomic nervous system by the Indian red scorpion venom is known to produce severe systemic manifestations, including cardiogenic shock and acute pulmonary oedema.

In adoptive T cell therapy (ACT), the direct cytotoxic effects of CD8 T cells on tumor cells, including the release of interferon-gamma (IFN-γ), are considered the primary mechanism for tumor eradication. Cancer antigen escape diminishes the T cell responses, thereby limiting the therapeutic success. The impacts of IFN-γ targeting non-tumor cells in ACT, on the other hand, remains under-investigated.
