Effect of prebiotics administered during embryo development on mitochondria in intestinal and immune tissues of adult broiler chickens.

Mitochondria are cellular organelles that are the place of many metabolic processes and thus have a significant impact on the proper functioning of the organism. These organelles respond easily to environmental stimuli and cellular energy demands. To ensure the proper functioning of mitochondria, a high supply of specific nutrients is needed.

Model with transmission delays for COVID-19 control: Theory and empirical assessment.

The paper focuses on modeling of public health measures to control the COVID-19 pandemic. The authors suggest a flexible integral model with distributed lags, which realistically describes COVID-19 infectiousness period from clinical data. It contains susceptible-infectious-recovered (SIR), susceptible-exposed-infectious-recovered (SEIR), and other epidemic models as special cases.

Predictive Value of Single or Combined Ultrasound Signs in the Diagnosis of Ovarian Torsion.

Objectives: To determine predictive values of isolated and combined ultrasound signs in the diagnosis of adnexal torsion.

Methods: This work was a retrospective study of 129 adult female patients who underwent an ultrasound examination followed by a definitive surgical procedure within a 24-hour period to determine whether adnexal torsion was present.

Results: The positive predictive value (PPV) of the ultrasound diagnosis of adnexal torsion was 82.

Hypermobility of the articular heads of the temporomandibular joint: pathology or variant of the norm?

Introduction: Among the large contingent of patients with TMJ dysfunctions, there are persons with hypermobility of the joint heads of the lower jaw. Moreover, at present, the question of the frequency of occurrence of hypermobility of articular heads of the TMJ is not reflected. The aim of the work is to find out the frequency of occurrence of hypermobility of articular head among a healthy population and to evaluate the clinical, radiological, and electromyographic characteristics of the muscular-articular complex in these individuals.
