This investigation aimed to assess the influence of birth weight on post-weaning fattening performance, meat quality, muscle fibre characteristics, and carcass traits in Karayaka lambs. The study categorized the lambs into three distinct groups based on birth weight: low birth weight (LBW), medium birth weight (MBW), and high birth weight (HBW). Throughout the fattening phase, the lambs were given access to food and water, culminating in the slaughter at the end of the study.

A Novel Ensemble Framework for Multi-Classification of Brain Tumors Using Magnetic Resonance Imaging.

Diagnostics (Basel)

February 2024

Department of Computer Engineering, Faculty of Engineering and Architecture, Tokat Gaziosmanpaşa University, Tokat 60250, Turkey.

Brain tumors can have fatal consequences, affecting many body functions. For this reason, it is essential to detect brain tumor types accurately and at an early stage to start the appropriate treatment process. Although convolutional neural networks (CNNs) are widely used in disease detection from medical images, they face the problem of overfitting in the training phase on limited labeled and insufficiently diverse datasets.

Center for Digital Health, Medical Science Research Institute, Kyung Hee University Medical Center, Kyung Hee University College of Medicine, 23 Kyungheedae-ro, Dongdaemun-gu, Seoul, 02447, South Korea.

Article Synopsis
  • A comprehensive study was conducted to estimate the global prevalence of functional dyspepsia (FD), analyzing data from 44 population-based studies involving over 256,000 participants from 40 countries from 1990 to 2022.
  • The overall global pooled prevalence of FD was found to be 8.4%, with the highest rates reported under Rome I criteria (11.9%) and the lowest under Rome IV criteria (6.8%), indicating variations by definition, geography, and demographic factors.
  • The prevalence of FD was notably higher in developing countries compared to developed ones (9.1% vs. 8.0%) and decreased over time from 12.4% in 1990

Aim: The aim of this study was to synthesize a library of novel di-sulfa drugs containing 1,3- diaryltriazene derivatives TS (1-13) by conjugation of diazonium salts of primary sulfonamides with sulfa drugs to investigate the cytotoxic effect of these new compounds in different cancer types and to determine their inhibitory activity against tumor-associated carbonic anhydrases IX and XII.

Materials And Methods: A carbonic anhydrase inhibitory activity of the obtained compounds was evaluated against four selected human carbonic anhydrase isoforms (hCA I, hCA II, hCA IX and hCA XII) by a stoppedflow CO hydrase assay. In addition, , cytotoxicity studies were applied by using A549 (lung cancer), BEAS-2B (normal lung), MCF-7 (breast cancer), MDA-MB-231 (breast cancer), CRL-4010 (normal breast epithelium), HT-29 (colon cancer), and HCT -116 (colon cancer) cell lines.

Background: In addition to the fact that the concept of passion in sports plays a significant role in the formation of the identity concept of athletes, the dedication of athletes to the sports branches they are interested in also has a significant impact on their passion for the sport they are interested in as well as their identity as an athlete. In this direction, the research aims to investigate the role of dedication as a mediator and moderator in the relationship between athlete identity and passion in sport.

Methods: The research was designed using the quantitative research technique of relational surveying.
