Organophosphate pesticides (OPs) are among the most widely used synthetic chemicals for the control of a wide variety of pests, and reactive oxygen species (ROS) caused by OPs may be involved in the toxicity of various pesticides. Previous studies have demonstrated that a reactivation of latent Epstein-Barr virus (EBV) could be induced by oxidative stress. In this study, we investigated whether...

OBJECTIVES To describe oropharyngeal stenosis (OPS), a potential complication of multilevel, single-stage upper airway surgery involving lingual tonsillectomy in children, and to discuss the manner in which OPS may be managed successfully. DESIGN Case series with an average follow-up of 12 months. SETTING Tertiary care children's hospital. PATIENTS Medical charts were reviewed for 104 pat...

Lipases sensitive to organophosphorus (OP) inhibitors play critical roles in cell regulation, nutrition, and disease, but little is known on the toxicological aspects in mammals. To help fill this gap, six lipases or lipase-like proteins are assayed for OP sensitivity in vitro under standard conditions (25 degrees C, 15 min incubation). Postheparin serum lipase, lipoprotein lipase (LPL) (two so...

Staphylococcus aureus assembles the siderophore, staphyloferrin B, from l-2,3-diaminopropionic acid (l-Dap), α-ketoglutarate, and citrate. Recently, SbnA and SbnB were shown to produce l-Dap and α-ketoglutarate from O-phospho-l-serine (OPS) and l-glutamate. SbnA is a pyridoxal 5'-phosphate (PLP)-dependent enzyme with homology to O-acetyl-l-serine sulfhydrylases; however, SbnA utilizes OPS inste...

A field trial of 4K uncompressed streaming over 80 (8λ x 10) Gbps colored optical packet switching network with SOA based broadcast-and-select switch and stacked optical-code (OC) label processing is reviewed. Introduction “4K” motion pictures (3840x2048 pixels), which is 4 times pixel counts of high-definition (HD), are promising imaging technology for digital cinema, computer visualization, a...

S U M M A R Y On Earth, oceanic plates subduct beneath a variety of overriding plate (OP) styles, from relatively thin and negatively buoyant oceanic OPs to thick and neutrally/positively buoyant continental OPs. The inclusion of an OP in numerical models of self-consistent subduction has been shown to reduce the rate that subducting slabs roll back relative to the equivalent single plate model...

Background: Commonly consumed vegetables from local markets are considered at a higher risk for organophosphate insecticides (OPs) contamination. This study aimed to investigate the contamination of OP residues in commonly vegetable samples 5 provinces, i.e., Nan, Chiang Rai, Lamphun, Lampang, and Mai provinces located Northern Thailand. A assessment OPs among adult Thai population was also eva...

This study focused on the situation surrounding community-based retail co-ops before and after COVID-19 pandemic considered its impact co-ops’ supply. The found that increase in supply of is significantly affected by number new members. Further, increased use services existing members was also affected. Due to state emergency, demand for dining out decreased, home-cooked prepared meals increase...

The main toxicity of organophosphorus pesticides (OPs) is neurotoxicity, which is caused by the inhibition of acetylcholinesterase. OPs also affect immune responses including effects on antibody production, IL-2 production, T cell proliferation, decrease of CD5 cells, and increase of CD26 cells and autoantibodies. However, there have been few papers investigating the mechanism of OP-induced inh...
