Plant growth Enhancement in Colchicine-Treated Tomato Seeds without Polyploidy Induction.

Plant breeding plays a pivotal role in the development of improved tomato cultivars, addressing various challenges faced by this crop worldwide. Tomato crop yield is affected by biotic and abiotic stress, including diverse pathogens and pests, extreme temperatures, drought, and soil salinity, thus affecting fruit quality, and overall crop productivity. Through strategic plant breeding approaches, it is possible to increase the genetic diversity of tomato cultivars, leading to the development of varieties with increased resistance to prevalent diseases and pests, improved tolerance to environmental stress, and enhanced adaptability to changing agroclimatic conditions.

[Isokinetic evaluation of the muscular strength and balance of knee extensor and flexor apparatus of taekwondo athletes].

Unlabelled: Lower limb strength and muscular balance are important attributes in the practice of Taekwondo.

Objective: To assess through isokinetic dynamometry the muscular strength and balance of knee extensor and flexor apparatus of elite Taekwondo athletes and to compare with recreational-type athletes.

Methods: The maximum torque, the angle of maximum torque, maximum torque work, total work of the series, average power, and flexor and extensor muscle apparatus balance of the knees were obtained.

[Subclinical findings in the knees of taekwondo athletes: diagnostic ultrasound study].

Unlabelled: Taekwondo is associated with an increased incidence of musculoskeletal injuries such as tendinopathy, synovitis, chondropathy, and ligament and meniscus injuries that may have an asymptomatic course in their initial stages, especially those located in the knee.

Objective: To describe the presence of morphostructural abnormalities in asymptomatic taekwondo athletes' (TKD) knees through the use of diagnostic ultrasound (US).

Methods: A cross-sectional, descriptive and comparative study.

[Validation of the SF-36 questionnaire in adults with asthma and allergic rhinitis in Mexican population].

Background: Multiple questionnaires demonstrated the effect of the disease on the Quality of Life (QL), especially on allergies. Asthma and allergic rhinitis contributes to the reduction of QL. One of the accepted instruments for the evaluation of QL in chronic diseases is the questionnaire SF-36 (SF-36).

[Asthma or laryngeal amyloidosis? A report of a case and literature review].

The laryngeal amyloidosis is an uncommon disease accounting for 1% of all benign lesions of larynx. The commonest symptom is the dysphonia, sometimes accompanied by stridor, laryngeal globus sensation, dysphagia and, in rare occasions, cough, dyspnea and hemoptysis, specially when the tracheobronchial tree is also affected. This paper describes the case of a 30-year-old female patient, whose main symptoms were progressive dysphonia and dyspnea, admitted at allergy service to rule out asthma.
