Pyrethroids are synthetic chemicals that account for 16% of the international insecticide market and have been shown to be of varying toxicity to different species. There are various methods available for detecting pyrethroids in agricultural products, but these products must be pre-treated to remove interference from the food matrix, such as through dispersion liquid-liquid microextraction (DLLME). This study employed two experimental design methods to optimize the continuous and discontinuous experimental parameters of DLLME and investigated whether DLLME combined with GC-NICI-MS is effective for detecting pyrethroids in agricultural products.

Massive localized lymphedema (MLL) is a benign overgrowth of lymphoproliferative tissue that is primarily observed in adults with class III obesity. Patients present with a painless mass that has usually been present for a considerable period. Consultation of a healthcare professional typically takes place when MLL-related complaints interfere with daily living.

Background: The Japanese giant silkworm (JGS) Caligula japonica is a significant defoliator pest in East Asia, causing severe economic losses in forest and fruit production. To establish a cost-effective biological control program against JGS, the age-stage, two-sex life table method was used to accurately assess the potential efficacy of two Mesocomys species (M. albitarsis and M.

Background The synthetic opioid tramadol is widely used as a pain reliever. Unlike other opioids, it is used freely worldwide, unaffected by international controls resulting in abuse and accidental intoxication. Analytical methods are necessary to prove tramadol abuse because 30% of the drug is excreted unchanged.

FtsZ is a bacterial protein that plays a crucial role in cytokinesis by forming the Z-ring. This ring acts as a scaffold to recruit other division proteins and guide the synthesis of septal peptidoglycan, which leads to cell constriction. In its native state, the FtsZ protein from Escherichia coli (EcFtsZ) is a multi-oligomer comprising dimers, trimers, tetramers, and hexamers in a dynamic self-association equilibrium depending on its concentration.
