This study was carried out to investigate the effect of Saccharomyces cerevisiae on growth performance, haematological and serum biochemical indices of rabbit bucks. Eighteen bucks were used for the study. They were assigned to three treatment groups with 6 bucks per treatment, replicated 3 times in a completely randomized design for twenty-eight (28) days. The bucks were allowed one week of acclimatization before the commencement of the study, during which they were fed commercial growers diets and forages. The bucks were fed a formulated ration supplemented with S. cerevisiae at 0.0, 0.3 and ..read more

The ACE2 gene polymorphisms (rs143936283, rs146676783, and rs4646116) in infected and noninfected persons by SARS-CoV-2 in Burkina Faso. Our cross-sectional study population comprised 137 SARS-CoV-2 infected persons and 181 non-infected persons. Three ACE2 gene polymorphisms rs143936283, rs146676783, and rs4646116, were genotyped using the real-time PCR standard TaqMan allelic discrimination technique. The association between SARS-CoV-2 infection and the polymorphisms were evaluated by a binary logistic regression. There was no association between the polymorphisms rs143936283, rs4646116 haplo ..read more

Growth curve measurements are fundamental operations in microbiology and molecular biology. Microplate readers have the advantage of high-throughput and automation. This allows for real-time monitoring of many bacterial cultures and a decrease in labor and costs. The volume and geometry of a well from a microplate imply that calibration and comparative studies must be performed before switching from one cultivation and growth monitoring system to another. Here, Escherichia coli XL1 Blue was used as a reference strain in order to test the feasibility of using a common, filter-based microplate r ..read more

Representative species of the Taxus genus, known since antiquity for their toxicity, have been an essential plant resource for the production of plant extracts with medicinal properties (anti-inflammatory, antifungal, and antibacterial) and, more recently, for the study of their allelopathic properties with significant implications in organic agriculture (bioherbicidal potential). With a view to the development of this new direction of research, the present work aims: to present a qualitative evaluation of two types of plant extracts (aqueous and alcoholic) of different concentrations (1% and ..read more

Osteosarcoma (OS), a malignancy primarily affecting children and adolescents, is the most frequently encountered malignant, non-hematologic, bone tumor. Despite the gradual improvement of survival rates, the management of this disease remains problematic due to challenges such metastasis development, its heterogeneous characteristics, and resistance to cytostatic drugs. Cold atmospheric plasma (CAP), a partially ionized gas operating at near room temperature, which is comprised of free carriers, excited or neutral molecules, and active radicals capable of initiating diverse physical phenomena ..read more

Several molecular marks have been used for various purposes since the beginning of contemporary molecular technology: Genetic resource characterization, core genetic resource collection, mapping, marker-assisted selection, and marker-assisted back crossing etc. The variety of all plant species, their genetic make-up, and the environments in which they dwell are considered to be components of biological diversity. Plant classification and identification can be done most quickly and simply using morphological examination. It has been established that molecular markers are effective instruments f ..read more

Background: Bovine spongiform encephalopathy (BSE) is a prion disease that is always fatal in cattle and is considered an important risk factor for human health. Genetic polymorphisms that alter prion proteins may be associated with susceptibility or resistance to infectious spongiform encephalopathy. Therefore, we investigated the distribution of the 23 bp indel variant in the prion protein (PRNP) gene in Jersey cattle in Turkey. Methods: A total of 95 unrelated Jersey cattle (79 of reproductive age and 16 of non-reproductive age) from a private farm in Izmir were included in the study. Genom ..read more

Background: Arthritis is an inflammatory disease that affects the joints. Patients suffering from chronic pain are anxious, which contributes to reducing the quality of life. The development of analgesic compounds with anxiolytic properties could prove to be of great interest for the treatment of chronic pain. The objective of the present study was to evaluate the analgesic and anxiolytic properties of the aqueous extract of the bark of the trunk of Diospyros mespiliformis in arthritic mice. Methods: Arthritis was induced by injection of 1% formaline into the left hind paw of the animals. Infl ..read more
