Concentration data of veterinary drugs in microalgae biomass collected from photobioreactors fed with piggery wastewaters are presented for the first time this work. To aim, a QuEChERS methodology and an ultrasound-assisted solid-liquid extraction have been assessed as sample preparation procedures purpose determining 20 drugs, mainly antibiotics different physico-chemical properties addition t...

Veterinary drug residues of common food (milk, meat) have posed serious threats to the environment and human health, making quality safety agricultural, livestock, aquatic products increasingly prominent. With widespread use veterinary drugs requirements for safety, it has become urgent detect in animal-derived foods. So far, few studies systematically reviewed progresses, challenges, future di...

In this research article, a new chromatographic method ultra-performance liquid chromatography (UPLC) was developed for the quantification of ivermectin (IMT)-preziquantel (PRZQ) in two-component mixture and veterinary dosage form mixture. The separation studied drugs (IMT PRZQ) carried out on Waters Acquity ® BEH C18 column (50mm x 2.1 mm i.d., 1.7 m) using mobile phase consisting water-aceton...

21 Code of Federal Regulations Part 556 (Tolerances for Residues of New Animal Drugs in Foods) is one of the Center for Veterinary Medicine's most significant set of regulations. However, in many respects, it is outdated. Subpart A (General Provisions) defines tolerance designations that are obsolete, while Subpart B (Specific Tolerances for Residues of New Animal Drugs) is inconsistent in term...

Veterinary and human medicines containing a sulphonamide are used to prevent infections in a variety of situations. For sulphonamide products that contain many components (e.g. four or more sulphonamides) chromatographic techniques are recommended [l-5]. However, for products formulated to contain a sulphonamide and another drug which increases the activity of the sulphonamide, simple, rapid an...

INTRODUCTION Platelets are vital components of normal hemostasis and key participants in pathologic thrombosis by virtue of their ability to adhere to injured vessels and to accumulate at sites of injury. Platelets have long been recognized as primary participants in arterial thromboembolism (TE). More recently, their role in venous thrombosis has been elucidated. Antiplatelet drugs interfere w...

BACKGROUND Few drugs are available for soil-transmitted helminthiasis (STH); the benzimidazoles albendazole and mebendazole are the only drugs being used for preventive chemotherapy as they can be given in one single dose with no weight adjustment. While generally safe and effective in reducing intensity of infection, they are contra-indicated in first-trimester pregnancy and have suboptimal ef...
