Exploring of miR-155-5p, miR-181b-5p, and miR-454-3p Expressions in Circulating Cell-Free RNA: Insights from Peripheral Blood of Uveal Malignant Melanoma Patients.

The identification of novel non-invasive biomarkers is imperative for the early diagnosis and monitoring of malignant melanoma. The objective of this study is to examine the expression levels of miR-155-5p, miR-181b-5p, and miR-454-3p in circulating cell-free RNA obtained from plasma samples of the 72 uveal malignant melanoma patients and to compare these levels with those of 72 healthy controls. The analysis showed that the expression level of the miR-181b-5p has increased 9.

Frequency of angiotensin II type 1 receptor gene polymorphism in Turkish acute stroke patients.

This study was performed in acute stroke patients in the Turkish population to determine the frequency of the A1166C polymorphism in the AT1 gene and to examine the role of this polymorphism in acute stroke development. In this study, 257 genomic DNA samples were analysed (from 206 acute stroke patients and 51 healthy individuals). Genomic DNA was prepared from peripheral blood using the salt-extraction method.

The preventive effect of polyvinylpolypyrrolidone on aflatoxicosis in broilers.

This study was conducted in order to evaluate the efficiacy of a polyvinylpolypyrrolidone for protection against aflatoxicosis in broiler chicks. For this purpose 132 day-old broiler chicks (Hybro) were used. They were divided into four groups, each of 33 chicks.

Efficacy of polyvinylpolypyrrolidone in reducing the immunotoxicity of aflatoxin in growing broilers.

1. Protective action of an enzyme-linked polyvinylpolypyrrolidone (PVPP, Mycofix Plus) against the immunosuppressive effect of afatoxins (AF) was evaluated by determination of peripheral blood T-lymphocyte proportions and splenic plasma cell counts. Histological changes in lymphoid organs were also investigated by light microscopy.

Embryotoxicity assay of aflatoxin produced by Aspergillus parasiticus NRRL 2999.

1. The embryotoxicity of mixed aflatoxins (AF) and aflatoxin B1 (AFB1) were evaluated by a modified chick embryotoxicity screening test (CHEST). Adverse effects on the early embryonic development of thymus and bursa of Fabricius were also investigated by light microscopy.
