ABSTRACT
ABSTRACT: Sánchez-Sabaté, J, Gutiérrez, H, Marco-Contreras, LA, Younes-Egana, O, Gonzalo-Skok, O, and Piedrafita, E. Influence of vertical-oriented vs. horizontal-oriented combined strength training in young basketball players. J Strength Cond Res 38(7): 1280-1287, 2024-This study aimed to compare the effects of 8-week combined vertical-oriented vs. horizontal-oriented training interventions in basketball athletes. Eighteen highly trained U-16 basketball players participated in this study and were randomly assigned to either a combined vertical-oriented training group (CVG, n = 9) or a combined horizontal-oriented training group (CHG, n = 9). Bilateral and unilateral vertical jump height, unilateral horizontal jump distance, 5-m, 10-m, and 20-m sprint times, change-of-direction sprint times, and a limb symmetry index were among the measured performance variables. Combined strength training was performed twice a week for 8 weeks. CVG was compounded by the squat exercise (3 sets of 6-8 R at 30-45% 1 repetition maximum [1RM]), jump squats (2 sets of 6 R, at 5-12.5% body mass [BM]), and vertical jumps (3-4 sets × 6 R). CHG included the hip thrust exercise (3 sets of 6-8 R at 30-45% 1RM), sled towing sprints (2-3 R, at 5-12.5% BM), and sprints (3-4 R of 20-m). Within-group differences showed significant ( p < 0.05 and statistical power >80%) improvements in unilateral vertical jumping with the right leg after both training interventions. By contrast, only CHG improved 5-m, 10-m, and 20-m sprint times ( p < 0.05 and statistical power >80%). Significant effects were observed for CHG compared with CVG in 5-m, 10-m, and 20-m sprint times ( p < 0.05 and statistical power >80%). This study reinforces the importance of oriented-combined training based on force-vector specificity target, mainly in horizontal-oriented actions.

The development of effective nanoparticle therapeutics has been hindered by their surface characteristics, such as hydrophobicity and charge. Therefore, the success of biomedical applications with nanoparticles is governed by the control of these characteristics. In this article, we report an efficient green capping method for gold nanoparticles (AuNPs) by a reduction with sodium citrate and capping with Virola oleifera (Vo), which is a green exudate rich in polyphenols and flavonoids. The Vo-capped AuNPs were characterized by UV, DLS, FTIR, Raman, TEM, DPPH, FRAP and their cytotoxicity was evaluated on the viability of Murine macrophage cell. The AuNPs had an average particle size of 15â¯nm and were stable over a long time, as indicated by their unchanged SPR and zeta potential values. These nanoparticles were assessed for their antioxidant potential using DPPH and FRAP and demonstrated the highest antioxidant activities and low cytotoxicity. We propose that the Virola oleifera-capped AuNPs have potential biomedical applications.

El siguiente trabajo prospectivo fue realizado en el Servicio de Cirugía II del Hospital Universitario de Caracas, durante el período comprendido entre marzo 1989 y noviembre de 1990, se incluyeron 87 pacientes (80,4 por ciento masculinos y 19,6 por ciento femeninos), con un promedio de edad de 37 años y 9 meses, bajo la modalidad de Hernia Inguinal: Cirugía Ambulatoria con anestesia Local. El 66,67 por ciento de los pacientes se operó en las primeras cuatro semanas luego de la primera consulta; La técnica quirúrgica más utilizada fue la de Bassini en el 67,8 por ciento de los casos, con un promedio de tiempo operatorio de 62 minutos. Se encontró un predominio de la hernia inguinal indirecta y derecha (39 y 62 por ciento respectivamente). La aceptación por parte del paciente fue buena en el 92 por ciento de los casos y en el 94,25 por ciento, los cirujanos apreciamos una buena tolerancia al procedimiento por parte del paciente. La morbilidad fue de 5,7 por ciento, sin mortalidad y sin recidivas hasta el momento. Mediante esta mortalidad, logramos además disponer de un mayor número de camas para otras patologías y ahorrar una cantidad significativa de dinero a la Institución.
