Case report: Hereditary spastic paraplegia with a novel homozygous mutation in .

Hereditary spastic paraplegia (HSP) is a group of neurodegenerative diseases with genetic and clinical heterogeneity characterized by spasticity and weakness of the lower limbs. It includes four genetic inheritance forms: autosomal dominant inheritance (AD), autosomal recessive inheritance (AR), X-linked inheritance, and mitochondrial inheritance. To date, more than 82 gene loci have been found to cause HSP, and SPG15 () is one of the most common autosomal recessive hereditary spastic paraplegias (ARHSPs) with a thin corpus callosum (TCC), presents with early cognitive impairment and slowly progressive leg weakness.

Targeting DNA-PK overcomes acquired resistance to third-generation EGFR-TKI osimertinib in non-small-cell lung cancer.

The third-generation of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs), represented by osimertinib, has achieved remarkable clinical outcomes in the treatment of non-small-cell lung cancer (NSCLC) with EGFR mutation. However, resistance eventually emerges in most patients and the underlying molecular mechanisms remain to be fully understood. In this study, we generated an osimertinib-acquired resistant lung cancer model from a NSCLC cell line H1975 harboring EGFR L858R and T790M mutations.

MicroRNA-210-3p Targets RGMA to Enhance the Angiogenic Functions of Endothelial Progenitor Cells Under Hypoxic Conditions.

Endothelial progenitor cells (EPCs) are multipotential stem cells considered to have immense clinical value for revascularization. However, the clinical application of EPCs has been hampered by their clinical potency in ischemic anoxic environments. This study aimed to explore the effect of microRNA-210 (miR-210) on EPCs under oxygen-glucose deprivation (OGD) conditions.

A total of 251 consecutive patients with acute ischemic stroke were recruited. They were divided into three groups depending on whether PSD had occurred at 2 weeks or 3 months since stroke: early-onset PSD, late-onset PSD, and non-depressed group.

Comparison Study of ASCO and TOAST Classification System in Chinese Minor Stroke Patients.

Background: Precise subtype classification based on underlying pathophysiology is important to prevent recurrent attack in minor stroke patients. A newly developed Atherosclerosis, Small vessel disease, Cardiac source, Others (ASCO) phenotypic classification system aims to characterize patients using different grades of evidence for stroke subtypes. However, this system has not been specifically applied to minor stroke population.

[Voltage-activated potassium channel blockers inhibit anisodamine-induced relaxation of rabbit aortic smooth muscles precontracted with noradrenaline].

Anisodamine, which is originally extracted from scopolia tangutica and is currently produced in China, is a tropane alkaloid and a muscarinic cholinoceptor blocker. Our previous study found that anisodamine did not alter high K(+)-evoked contraction of rabbit aortic rings using isometric tension recording methods, but could attenuate noradrenaline (NA)-, histamine- or 5-hydroxytryptamine-induced contraction in an endothelium-independent manner. Since the high K(+)-elicited depolarization non-selectively inhibits potassium channels in vascular smooth muscle cell (VSMC) membrane, the vasodilation effect of some potassium channel activators may be inhibited or abolished in high K(+) solution.
