Analytical prediction of genetic contribution across multiple recurrent backcrossing generations.

We derive formulas for the residual donor genome content during trait introgression via recurrent backcrossing and use these formulas to predict (without simulation) residual donor genome content for five future generations. Trait introgression is a common method for introducing valuable genes or alleles into breeding populations and inbred cultivars. The particular breeding scheme is usually designed to maximize the genetic similarity of the converted lines to the recurrent parent while minimizing cost and time to recover the near isogenic lines.

Reduction of Dental Anxiety in Children Using Virtual Reality: A Randomised Controlled Trial.

Aim: The aim of this research is examining the effectiveness of Virtual Reality (VR) in the reduction of dental anxiety in children with novel methods.

Methods: The three arm parallel-group randomised clinical study was conducted in children aged 6-10 years. Pulpotomy procedure was performed on randomised 90 selected children (n=30 in each group; AG: group applied active distraction using VR glasses, PG: group applied passive distraction, i.

Electromyographic analysis of the traditional and spin throwing techniques for goalball games related to ball velocity for selected upper extremity muscles.

Background: Goalball is a popular sport among visually impaired individuals, offering many physical and social benefits. Evaluating performance in Goalball, particularly understanding factors influencing ball velocity during throwing techniques, is essential for optimizing training programs and enhancing player performance. However, there is limited research on muscle activation patterns during Goalball throwing movements, needing further investigation to address this gap.

Sensory function and somatosensorial system changes according to visual acuity and throwing techniques in goalball players: A cross-sectional study.

The somatosensory system is a complect sensory system that differentiates individual athletes. The aim of this study is to investigate the effect of visual acuity level on throwing technique, proprioceptive sense of the shoulder joint, light touch and two-point discrimination sense of the upper extremity, and sensory function (postural control and reaction time) in visually impaired goalball players. Goalball players who have different visual acuities B1(unable to perceive light or recognize its shape); B2 (has a visual field of less than 5 degrees and can recognize shapes); B3 (visual field greater than 5 degrees and less than 20 degrees) participated in the study.

Mental and Psychosomatic Effects of the Coronavirus Disease 2019 Pandemic on Adolescents: A Validation Study.

Objectives: The coronavirus disease 2019 (COVID-19) pandemic has had detrimental impacts on both physical and mental health worldwide. In addition to the behavioral effects, it has caused a range of psychological problems such as depression, anxiety, sleep disorders, and anger. Fear and stress have been particularly prevalent in individuals.
