Long-term exposure to polycyclic musk tonalide - A potential threat to juvenile zebrafish ()?

Polycyclic musk compounds are commonly used in personal care products to replace expensive natural fragrances. Due to their huge consumption, they have become a part of the aquatic environment. In the present study, a two-month exposure effect of tonalide on juvenile zebrafish () was investigated.

Efficacy and safety of higher oral doses of azaperone to achieve sedation in pigs.

The aim of this study is to evaluate the possibility of achieving more effective and prolonged sedation in pigs by the oral administration of increased doses of azaperone and to evaluate its safety. This was performed through a prospective randomised and double blinded study. A total of 32 weaned piglets were divided into 4 groups (8 in each group).

Use of IHF-QD Microscopic Analysis for the Detection of Food Allergenic Components: Peanuts and Wheat Protein.

The aim of the study was to analytically evaluate quantum dots in immunohistofluorescence (IHF-QD) microscopic imaging as detectors of food allergens-peanut and wheat. The experiment was designed as two in silico experiments or simulations: (a) models of pastry samples were prepared with the addition of allergenic components (peanut and wheat protein components) and without the addition of allergenic components, and (b) positive and negative commercial samples underwent food allergen detection. The samples from both simulations were tested by the ELISA and IHF-QD microscopic methods.

Comprehensive fitness evaluation of common carp (Cyprinus carpio L.) after twelve weeks of atrazine exposure.

Atrazine is frequently detected in surface waters and negatively affect physiological function in aquatic organisms. Even though numerous authors have intensively studied its toxicity, only limited information concerning the long-term fish exposure is available. The aim of this study was evaluation of chronic exposure in common carp.

Herpesvirus associated dermal papillomatosis in Williams' mud turtle Pelusios williamsi with effects of autogenous vaccine therapy.

An adult female of Williams' mud turtle, Pelusios williamsi long-term captive, that was allegedly caught wild in Kenya was found to have developed papilloma-like skin lesions. Excised tumors were examined histologically after routine processing with hematoxylin and eosin (H & E) stained slides, examined for the presence of viral particles by electron microscopy employing negative staining, and examined for the presence of viral DNA by PCR. Microscopic features in pre-treatment biopsies were fully diagnostic and consistent with multifocal squamous cell papilloma.
