background: identification of regional pattern of poisoning is essential for health care authorities for proper planning on prevention programs and optimized management of antidote stockpiles. this study was designed to evaluate one-year epidemiologic pattern of acute poisoning cases treated at a tertiary care hospital in thrissur, india. methods: in this retrospective cross sectional study, me...

background:the pattern of poisoning has a regional variability. this study was carried out to describe the epidemiological profile of acute poisoning in northeastern bangladesh and to evaluate the mortality. methods:in this retrospective cross-sectional study, medical records of poisoned patients treated at department of medicine of sylhet m.a.g. osmani medical college hospital, sylhet, banglad...

background: migrant farmworkers are prone to several psychosocial stressors. objective: to investigate the effect of perceived psychosocial factors on pesticide exposure among seasonal migrant hispanic farmworkers in north carolina, usa. methods: a cross-sectional interview survey of 187 seasonal migrant farmworkers of mexican descent, identified from labor camps located in rural counties in no...

Colloidal chemically converted graphene sheets (CCGs) are able to contact with each other to form stable self-assembled stacked-CCGs via salt "invasion", which can serve as powerful building blocks for capturing double-stranded DNA.

Background: Identification of regional pattern of poisoning is essential for health care authorities for proper planning on prevention programs and optimized management of antidote stockpiles. This study was designed to evaluate one-year epidemiologic pattern of acute poisoning cases treated at a tertiary care hospital in Thrissur, India. Methods: In this retrospective cross sectional study, me...

Two types of graphene nanoribbons: (a) potassium-split graphene nanoribbons (GNRs), and (b) oxidative unzipped and chemically converted graphene nanoribbons (CCGNRs) were investigated for their magnetic properties using the combination of static magnetization and electron spin resonance measurements. The two types of ribbons possess remarkably different magnetic properties. While a low-temperat...

background: the term caustic generally refers to alkaline and the term corrosive generally refers to acidic agents' injury however, in medical literature caustic is frequently a term applied to both substances. ingested alkali typically damage the esophagus more than stomach or duodenum, whereas acids usually cause more severe gastric injury. since esophagus has a slightly alkaline ph, its...

Cross-metathesis (CM) has recently emerged as a viable strategy for protein modification. Here, efficient protein CM has been demonstrated through biomimetic chemical access to Se-allyl-selenocysteine (Seac), a metathesis-reactive amino acid substrate, via dehydroalanine. On-protein reaction kinetics reveal a rapid reaction with rate constants of Seac-mediated-CM comparable or superior to off-p...

Large-scale identification of metabolites is key to elucidating and modeling metabolism at the systems level. Advances in metabolomics technologies, particularly ultra-high resolution mass spectrometry (MS) enable comprehensive and rapid analysis of metabolites. However, a significant barrier to meaningful data interpretation is the identification of a wide range of metabolites including unknow...

We present an abundance analysis of light elements in the most massive chemically peculiar (CP) stars, He-rich stars. The analysis is based on both low and high-resolution observations collected at ESO, La Silla, Chile in the optical region and includes 6 standard and 21 He-rich stars. Light element abundances display a diverse pattern from under-solar up to above-solar values. Carbon is found ...
