Abstract Acetylcholinesterase (AChE; EC 3.1.1.7) inhibition in vitro is an effective method for monitoring pesticide contamination, particularly organophosphates, offering advantages over vivo approaches. Environmental factors like temperature, age, and stress can alter enzyme activity vivo, making controlled studies necessary. This research focused on the brain AChE of Nile tilapia (Oreochromis niloticus), a key species global aquaculture, to detect organophosphate contamination. The study...
This study developed a biosensor for the detection of pesticides, particularly organophosphates, employing an enzymatic inhibition technique using ECPP (Genyatremus luteus), natural source acetylcholinesterase. The stonefish is found from Antilles to southern Brazil and important fishery resource states Maranhão Pará. species prominent in artisanal fisheries along coast Maranhão, standing out among several economically significant due its high abundance popularity population state where it...
Cervical cancer is caused by a persistent and high-grade infection. It the Human Papillomavirus (HPV), which, when entering cervical cells, alters their physiology generates serious lesions. HPV 18 among those most involved in carcinogenesis this region, but there are still no drug treatments that cause cure or total remission of lesions HPV. known L-asparaginase an amidohydrolase, which plays significant role pharmaceutical industry, particularly treatment specific cancers. Due to its...
Amylases are enzymes that represent approximately 25% of the global enzymatic market, presenting a widespread biotechnological application. This study aimed at extracting, purifying, and characterizing amylases from mid intestine gland (MIG) Ucides cordatus to evaluate their sensitivity metallic ions as source for environmental monitoring. The crude extract obtained MIG was subjected partial two-step purification: thermal treatment precipitation with ammonium sulfate in two fractions (F1:...
Obesity is a chronic disease with high prevalence, now recognized as global epidemic. Studies show strong association between body mass index (BMI) and various diseases, including non-alcoholic fatty liver (NAFL), cardiovascular diabetes, musculoskeletal disorders, kidney disease, mental health issues. These conditions negatively impact quality of life elevate healthcare costs (Boutari et al., 2022). Objective: This study explores exogenous lipase produced by the fungus Fusarium solani...
The acai oil, extracted from Euterpe oleracea, has a wide range of promising biological activities, being produced on large scale in Brazil, mainly the Amazon region. Studies highlight its health benefits, including antimicrobial activity, anticancer action, antiatherogenic, anti-hypercholesterolemic, anti-hypertriglyceridemic, anti-inflammatory, and antinociceptive. Acai berry oil also shows potential technological production. This prospecting was carried out between 2014 2023 to identify...
