Observing the effect of physical activity on forward head posture and rounded shoulder posture in young healthy adults.

[Purpose] This study aimed to examine the effects of physical activity on forward head and rounded shoulder postures in healthy young adults. [Participants and Methods] We recruited 20 healthy young adults engaged in high levels of physical activity and 20 healthy young adults engaged in low levels of physical activity. Both groups completed the International Physical Activity Questionnaire (IPAQ) to assess their physical activity levels.

Serratus Anterior and Upper Trapezius Electromyographic Analysis of the Push-Up Plus Exercise: A Systematic Review and Meta-Analysis.

Context: Whereas the serratus anterior (SA) and the upper trapezius (UT) work as a force couple for scapular motion, weakness of the SA and overactivation of the UT are often present in overhead athletes with shoulder dysfunction. Therefore, researchers addressing an intramuscular imbalance between the SA and UT have focused on finding exercises that target the weak SA and minimally activate the UT.

Objective: To compare the effectiveness of push-up plus (PUP) exercise variants based on the electromyographic (EMG) activity of the SA and UT.

Production, IMAC purification, and molecular modeling of N-carbamoyl-D-amino acid amidohydrolase C-terminally fused with a six-his peptide.

A six-His peptide was genetically engineered to the C-terminus of Agrobacterium radiobacter N-carbamoyl-D-amino acid amidohydrolase monomer to facilitate the protein purification with immobilized metal affinity chromatography (IMAC). The fusion enzyme, named as DCaseH, was overexpressed in Escherichia coli and one-step IMAC-purified. The production study showed that DCaseH was optimally produced at 15 degrees C for 25 h by the induction of 0.
