Panax notoginseng saponins promote hair follicle growth in mice via Wnt/β-Catenin signaling pathway.

Panax notoginseng saponins (PNS), the active ingredients of the traditional Chinese medicine Panax notoginseng, have strong neuroprotective and anti-platelet aggregation effects. To investigate whether PNS can promote hair follicle growth in C57BL/6J mice, the optimal concentration of PNS was initially determined, followed by clarification of the mechanism underlying their effects. Twenty-five male C57BL/6J mice had the hair on a 2 × 3 cm area of the dorsal skin shaved and were equally divided into five groups: control group, 5% minoxidil (MXD) group, and three PNS treatment groups [2% (10 mg/kg), 4% (20 mg/kg), and 8% (40 mg/kg) PNS].

Post-stroke seizure-Do the locations, types and managements of stroke matter?

Objective: To determine the incidence of post-stroke seizures and the associated risk factors in a government-restructured hospital in Singapore.

Methods: This retrospective study included consecutive patients (age ≥21 years) admitted to the stroke rehabilitation facility at Changi General Hospital, Singapore, between June 2008 and May 2017, with a minimum post-discharge follow-up of 6 months. Patients with known epilepsy central nervous system infection or tumor, a history of neurosurgery and or missing data were excluded from study.

Stroke in Myanmar: attitudes and treatment.

The burden of stroke in low-middle-income countries has increased during the past few decades but has decreased in developed countries and it is important to know why; though it may be attributed primarily to attitudes toward stroke management and prevention among doctors, and consequently in the population. We have conducted a study to investigate how stroke is managed in Myanmar, south-east Asia, with a population of approximately 60 million. We found that attitude differed markedly from that reflected in international guidelines.
