Running-specific prosthesis' performance characterization by dynamic finite element approach.

Introduction: Composite running-specific prostheses (RSP) are widely used by athletes with lower limb amputations to simulate the spring-like behavior of biological legs. However, the effect of these devices on the biomechanics of athletes with transtibial amputations remains uncertain.

Modeling Method Description: To address this issue, this study proposes a time-dependent finite element model that uses angles and dynamic loads during ground contact to evaluate RSP performance parameters such as stiffness and energy efficiency.

Cranial nerve involvement among COVID-19 survivors.

Introduction: COVID-19 was first reported in November 2019 in China and rapidly spread across the globe. COVID-19 causes neurologic symptoms and complications, which may persist even after recovery in patients. The objective of this research was to determine the involvement of cranial nerves in COVID-19 survivors.

Prevalence of depression and anxiety among myasthenia gravis (MG) patients: A systematic review and meta-analysis.

Objective: Myasthenia gravis (MG) people experience adverse psychiatric outcomes, which may impact on their life and disturb their daily activity. Depression and anxiety are identified as significant psychiatric problems that MG people face. However, there is no sufficient epidemiological information about depression and anxiety-based publication.

Iranian plant : an overview of botany, traditional uses, phytochemistry and pharmacology.

commonly known as "Serish" is a valuable ornamental plant with culinary uses and also utilized in traditional medicine for treating Gastrointestinal diseases. This comprehensive study was performed to investigate the pharmacological and biological effects of and the compounds identified and isolated from it in order to encourage researchers to study it further. Despite the few number of studies on the ethnopharmacology of the plant , however studies conducted on either crude extracts, solvent fractions or isolated pure compounds from a varied range of biological effects comprising antibacterial, anti-fungal, anti-diabetic and etc.

Nicotinic acetylcholine receptors control acetylcholine and noradrenaline release in the rodent habenulo-interpeduncular complex.

Background And Purpose: Nicotinic acetylcholine receptors (nACh receptors) play a central role in the habenulo-interpeduncular system. We studied nicotine-induced release of NA and ACh in the habenula and interpeduncular nucleus (IPN).

Experimental Approach: The habenula and IPN were loaded with [(3) H]-choline or [(3) H]-NA and placed in superfusion chambers.
