Experimental study on the deformation localisation and acoustic emission characteristics of coal in Brazilian splitting tests.

This paper presents an experimental study to assess the behaviour of coal samples under tensile loadings to better understand the failure mechanisms and the interactions with the coal characteristics. A set of Brazilian splitting tests were carried out using disk specimens obtained from Tashan Coal Mine in China. The digital speckle correlation method and acoustic emission (AE) were used to capture the deformation localisation and AE characteristics of each specimen during the loading process.

miR-19a/b-3p promotes inflammation during cerebral ischemia/reperfusion injury via SIRT1/FoxO3/SPHK1 pathway.

Background: Stroke affects 3-4% of adults and kills numerous people each year. Recovering blood flow with minimal reperfusion-induced injury is crucial. However, the mechanisms underlying reperfusion-induced injury, particularly inflammation, are not well understood.

Inordinate glucose variation poststroke is associated with poor neurological improvement in patients without history of diabetes.

Introduction: Glucose variation is an important risk factor for the complications of diabetes mellitus. The plasma glucose level poststroke is in continuous fluctuation. However, whether the variation influences neurological improvement remains unknown.

[Association of plasma homocysteine and cystathionine beta-synthase polymorphism with cerebral thrombosis].

Objective: To study the association of plasma homocysteine (Hcy) and polymorphism and cystathionine beta-synthase (CBS) with cerebral thrombosis.

Methods: Eighty-seven patients with first-ever acute cerebral thrombosis and 80 control subjects were examined for plasma Hcy levels using high-performance liquid chromatography-fluorescence detection and for CBS polymorphism determined by amplification refractory mutation system.

Results: The fasting plasma Hcy level was l5.

[Early diagnosis and treatment of intracranial venous thrombosis].

Objective: To study the early diagnosis and treatment of intracranial venous thrombosis.

Method: The etiology, clinical manifestations, presentations in cerebral CT and magnetic resonance imaging (MRI), electroencephalogram (EEG) features, and the results of cerebral spinal fluid and blood rheological examinations were analyzed in 8 cases of intracranial venous thrombosis.

Results: Thrombosis often arose during the puerperium and from infection, with the frequent presentations of intracranial hypertension and focal neurological defect.
