Accidental ingestion of fish bones can lead to serious complications, such as gastrointestinal perforation and hepatic abscesses. This case series presents three instances where fish bone ingestion led to secondary GI tract perforation and the development of hepatic abscesses. It also emphasizes the importance of prompt diagnosis and intervention to prevent serious consequences.

Article Synopsis
  • * Quail given higher doses of acetochlor (20mg/kg, 30mg/kg, and 40mg/kg) showed reduced growth, changes in crowing behavior, and significant alterations in blood parameters, including decreases in red blood cells and hemoglobin levels.
  • * Histopathological examinations revealed serious lesions in key organs such as testes, heart, and brain, illustrating that even low acetochlor concentrations can adversely affect the physical and biochemical health of Japanese quail.

Hyperlipidemia is a key risk factor mainly for hypertension and cardiac abnormalities. Previously eucalyptus plant (river red gum) had been used for its medicinal value for the treatment of many ailments. This study focused on phytochemical examination, investigation of an potential and effects in mice fed with high cholesterol diet, GC-MS analysis of extracts of leaves and further confirmation of anti-hyperlipidemic potential of different constituents of plant extracts by using technique.

Melatonin, being an endogenous signaling molecule plays important role in plant growth and stress alleviation. The present study was conducted to evaluate the ameliorative role of melatonin against Cr toxicity in maize seedlings. The Cr toxicity (50, 100 and 200 µM) severely affected hydroponically grown seedlings growth in a dose-dependent manner; however, the melatonin (0.

Wastewater used as irrigation water is causing heavy metal accumulation in the agro-ecosystems. A greenhouse study was conducted to compare the phytoaccumulation ability of four agroforestry tree species under different wastewater treatments. Three-month-old potted seedlings of , , , and were irrigation with tap water (C), municipal wastewater (MWW), and industrial wastewater (IWW).

Lipid-based self-nanoemulsifying drug delivery systems (SNEDDS) have resurged the eminence of nanoemulsions by modest adjustments and offer many valuable opportunities in drug delivery. Chlorpromazine, an antipsychotic agent with poor aqueous solubility-with extensive first-pass metabolism-can be a suitable candidate for the development of SNEDDS. The current study was designed to develop triglyceride-based SNEDDS of chlorpromazine to achieve improved solubility, stability, and oral bioavailability.

Antioxidants acts as a defense mechanism that protects against oxidative damage caused by free radicals produced in the body. Medicinal plants are preferably used for various diseases in many countries. The studies were conducted to determine the antioxidant capacity of the ethanolic leaves and fruits extracts of Physalis minima, Withania somnifera, Datura inoxia, Solanum nigrum and Kigelia africana by 1, 1-diphenyl-2-picrylhydrazyl (DPPH) free radical scavenging assay.

Intramacrophage parasite 'Leishmania' has developed various mechanisms for proficient uptake into macrophages and phagosome regulation to avoid macrophage's oxidative burst induced by peroxide, hydroxyl radical, hypochlorous acid and peroxynitrite production. One major barrier for impairing the accession of old fashioned anti-Leishmanial drugs is intrinsic incapability to pass through cell membranes and limiting their abilities to ultimately destroy intracellular pathogens. Receptor-mediated targeted drug delivery to the macrophages by using nanoparticles emerges as promising strategy to improve therapeutic efficacy of old-fashioned drug.
