Bioconversion of cow manure through vermicomposting: effects of tylosin concentration on the weight of worms and manure quality.

This study investigated batch-fed vermicomposting of cow manure, with a specific focus on assessing the effects of tylosin on the weight of earthworms and the overall quality of the resulting manure. Five reactors, including three concentrations of tylosin (50, 100, and 150 mg/kg) and two control reactors, were employed. Residual tylosin concentrations were measured using high-performance liquid chromatography (HPLC).

Toll-like receptor 4 plays significant roles during allergic rhinitis.

Allergic rhinitis is a nasal hypersensitivity and allergic disease which leads to inflammation of nasal mucosa. Previous investigations revealed that innate immune receptors play a key role in the pathogenesis of inflammatory diseases including allergic diseases. Toll-like receptors (TLRs), which are important innate immune receptors, play crucial roles in the recognition of foreign antigens, including allergens, and subsequently for the induction of immune responses such as inflammation.

Effect of opium smoking cessation on the nasopharyngeal microbial flora.

Objective: To determine the effect of opium smoking cessation on the frequency and type of microorganisms in the nasopharynx of opium smokers.

Methods: This cross-sectional study was performed in the Psychiatry, and Ear, Nose, and Throat Departments, Moradi Hospital, Rafsanjan University of Medical Sciences, Rafsanjan, Iran from June to November 2008. Nasopharyngeal cultures were taken from 50 opium smokers before, and 2-3 months after cessation of opium smoking.
