Effects of a Multicomponent Exercise Program on Groups of Community-Dwelling Older Adults with Low Schooling: A Pilot Study.

The aim of this study was to analyze the effects of a multicomponent exercise program on the physical and hemodynamic functions of community-dwelling older adults with low schooling levels in relation to simple multicomponent group exercises. Twenty-one older people were randomly assigned to two groups: G1 ( = 11) and G2 ( = 10); sixteen of whom completed the sixteen sessions over a six-week period, three times a week. During eight sessions, G1 performed adapted dual-task multicomponent exercises (strengthening, balance, and cognition) and G2 simple multicomponent exercises (strengthening and balance), and both groups engaged in eight additional sessions of simple multicomponent exercises.

Association between ocular toxoplasmosis and APEX1 and MYD88 polymorphism.

Ocular toxoplasmosis (OT) is the most common form of posterior uveitis, and in some countries, it is the most frequent cause of visual impairment. Studies demonstrate that the polymorphism in genes involved with the immune response can be related both to the occurrence and to the recurrence of OT. Thus, the present study aimed to analyze the association between OT and the polymorphism of the APEX1 (rs1130409) and MyD88 (rs7744) genes.

Ploidy manipulation and polyploid detection in the white shrimp Litopenaeus vannamei (Boone 1931) (Decapoda, Penaeidae).

Ploidy manipulation has been rarely used in the genetic improvement of cultured marine shrimps. Although polyploid induction has been proven to be successful in Penaeids, including the species Litopenaeus vannamei, the methodology still requires some improvements. In the present work, different thermal shock treatments on ploidy manipulation were tested and a protocol for detecting polyploid individuals was also established.
