Exploring the impact of occupational exposure: A study on cardiovascular autonomic functions of male gas station attendants in Sri Lanka.

Fuel dispensing at fuel stations is performed manually by unprotected male gas station attendants in Sri Lanka, who have long working hours. These workers are exposed to hydrocarbon fuels associated with multiple health effects by modulation of the autonomic nervous system. This study was performed to determine cardiovascular autonomic functions among fuel pump attendants in Sri Lanka.

Dihydropyrimidinase enzyme deficiency and congenital isolated adrenocorticotrophin deficiency: dual genetic diagnosis in a Sri Lankan boy.

We report on a male patient who was investigated for frequent apneic episodes, feeding problems, hypotonia, and left-sided middle cerebral artery infarction in the magnetic resonance imaging at 2 weeks of age. Primary diagnosis of dihydropyrimidinase (DPYS) deficiency was suspected following the analysis of urine for organic acid; DPYS deficiency was strongly suggested by the presence of dihydrouracil, thymine, and uracil. Subsequent genetic evaluation by whole exome sequencing revealed 2 separate mutations, homozygous pathogenic variant c.

Chloride-Based Additive Engineering for Efficient and Stable Wide-Bandgap Perovskite Solar Cells.

Metal halide perovskite based tandem solar cells are promising to achieve power conversion efficiency beyond the theoretical limit of their single-junction counterparts. However, overcoming the significant open-circuit voltage deficit present in wide-bandgap perovskite solar cells remains a major hurdle for realizing efficient and stable perovskite tandem cells. Here, a holistic approach to overcoming challenges in 1.

Multiscale modeling of the cellular uptake of C6 peptide-siRNA complexes.

In gene therapy utilising short interfering RNA (siRNA), delivery of the siRNA therapeutics to the target site is a major obstacle, due to low cellular uptake. Efficient delivery systems such as cell penetrating peptides (CPPs) are in the forefront for the development of efficient, safe, non-viral gene delivery. The C6 peptide series are a class of synthetic CPPs, developed specifically for the delivery of siRNA.
