A novel polymer composite from polyhexamethylene guanidine hydrochloride for high performance triboelectric nanogenerators (TENGs).

In this study, we report the successful fabrication of a novel antibacterial triboelectric nanogenerator (TENG) using a polymer composite film based on polyhexamethylene guanidine hydrochloride (PHMG). The composite materials, with optimised ingredient ratios, consist of PHMG, polyvinyl alcohol (PVA) and glutaraldehyde (GA) as a crosslinking agent (PHMG-GA-PVA). Utilising 3D printing, these composite materials were directly deposited on the conductive substrates and used as positive TENG electrodes.

Three Novel Pathogenic Variants in Unrelated Vietnamese Patients with Cardiomyopathy.

: Cardiomyopathy, including dilated cardiomyopathy (DCM) and hypertrophic cardiomyopathy (HCM), is a major cause of heart failure (HF) and a leading indication for heart transplantation. Of these patients, 20-50% have a genetic cause, so understanding the genetic basis of cardiomyopathy will provide knowledge about the pathogenesis of the disease for diagnosis, treatment, prevention, and genetic counseling for families. : This study collected nine patients from different Vietnamese families for genetic analysis at The Cardiovascular Center, E Hospital, Hanoi, Vietnam.

Imaging features of the brachial plexus in neurogenic thoracic outlet syndrome: A case report.

Neurogenic thoracic outlet syndrome (NTOS) is characterized by the compression of the brachial plexus in the thoracic outlet region, caused by various etiologies. We report a case with clinical symptoms and imaging findings from ultrasound and magnetic resonance imaging (MRI) of NTOS due to an elongated C7 transverse process and a fibrous band of the middle scalene muscle, which was confirmed in decompression surgery.
