Clinical review and analysis of artery of Percheron infarction.

Artery of Percheron infarction is a rare one of the neurovascular structure variants of acute ischemic stroke characterized by bilateral paramedian thalamic infarcts (BTPI), with or without mesencephalic infarction. Due to the low occurrence rate and various clinical manifestations, the early diagnosis of this disease is often missed. In addition, it is also difficult to diagnose this disease in an early implementation phase because cranial imaging and intracranial vascular imaging may show negative results.

Association between homocysteine and multivascular atherosclerosis in stroke-related vascular beds determined by three-dimensional magnetic resonance vessel wall imaging.

Background: Atherosclerosis in stroke-related vascular beds is the major cause of stroke. Studies demonstrated that multivascular atherosclerosis is prevalent in stroke patients and those with multivascular plaques had higher risk of recurrent stroke.

Objectives: This study investigated the relationship between homocysteine and multivascular atherosclerosis in stroke-related vascular beds using magnetic resonance imaging.

A Seamless Gene Deletion Method and Its Application for Regulation of Higher Alcohols and Ester in Baijiu .

The security of engineering is becoming more focused on industrial production in consideration of the public concern regarding genetically modified organisms. In this work, a rapid and highly efficient system for seamless gene deletion in was developed through two-step integration protocol combined with endonuclease I-SCEI expression. The factors affecting the frequency of the second homologous recombination were optimized, and studies indicated that the mutant strains with 500 bp direct repeats and that have been incubating in galactose (0.

Effects of differences in serum total homocysteine, folate, and vitamin B12 on cognitive impairment in stroke patients.

Background: Vascular cognitive impairment-no dementia (VCIND) refers to the early or mild cognitive impairment induced by cerebral vascular injury. Research shows that serum total homocysteine (tHcy) level is an independent risk factor for cerebral vascular disease and may be closely related to cognitive function.Current studies on the tHcy level in VCIND patients are limited, and the relationship of tHcy with cognitive function remains unclear.

Polysomnographic abnormalities in patients with vascular cognitive impairment-no dementia.

Objectives: We aimed to investigate subjective sleep quality and polysomnographic sleep structure features in patients with vascular cognitive impairment-no dementia (VCIND).

Methods: Fifty-six patients with VCIND, 48 patients with simple stroke (without cognitive impairment), and 48 control subjects were included. The Pittsburgh Sleep Quality Index (PSQI) and polysomnography (PSG) were used to analyze their sleep characteristics.
