Somatotype and Digital Dermatoglyph in Mexican Football Players

La valoración de la forma corporal y de las capacidades físicas es una necesidad para la selección, clasificación y entrenamiento de los jugadores de futbol. El presente estudio examinó en futbolistas profesionales mexicanos (N = 49) la relación entre clases de somatotipo y clases de capacidades físicas de acuerdo a dermatoglifia dactilar. Las frecuencias de clases de somatotipo y clases de capacidad física fueron comparadas entre subgrupos de futbolistas. Una mayor proporción de futbolistas se caracterizó por somatotipo mesomorfo balanceado con dermatoglifia tipo 2 y 3 correspondiente a fuerza, fuerza explosiva y velocidad. Esto es consistente con hallazgos previos en futbolista

A safeguard approach to detect stagnation of GMRES(m) with applications in Newton-Krylov methods

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)Restarting GMRES, a linear solver frequently used in numerical schemes, is known to suffer from stagnation. In this paper, a simple strategy is proposed to detect and avoid stagnation, without modifying the standard GMRES code. Numerical tests with the proposed modified GMRES(m) procedure for solving linear systems and also as part of an inexact Newton procedure, demonstrate the efficiency of this strategy.272175199Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)PRONEX-OptimizationFundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq

A study of breakfast pattern in Indonesia, Malaysia, and Philippines

The quality of foods taken during breakfast could contribute in shaping diet quality. The International Breakfast Research Initiative (IBRI) conducted a standardized analysis of national nutrition surveys from Indonesia, Malaysia, and the Philippines to derive nutritional recommendations for a balanced breakfast

Niveles de fósforo disponible aparente en pollas Leghorn blanca durante las etapas de iniciación, crecimiento, desarrollo e inicio de postura

Phosphorus (P) is important for the growth and metabolism of pullets and young laying hens, although the requeriments of this mineral could be overvalued. An experiment was conducted with 750 Hy-line W-36 pullets to evaluate the effects of apparent available phosphorus (aaP) levels during starter (1 d to 6 wk), growing (7 to 12 wk), development (13 to 18 wk), and initial laying period. The analyzed variables were: body weight (BW), feed intake (FI), percentage of P in excreta (PPE) and tibia bone (TBP), tibia breaking strength (TBS), egg mass (EM), and specific gravity (SG). The evaluated aaP levels had no effect (P>0.05) on FI, FP, TBP, RB, or EM in the stages under study. There was a difference (P0.05) in the starter period, the optimum biological levels for growing and finishing stages were 0.28 and 0.26 % of aaP, respectively. It was concluded that the requirements of apparent available phosphorus could be lower than the value suggested by NRC (1994) for the growth stages and the variables measured, without affecting the body condition and bone mineralization of pullets.El fósforo es importante en el metabolismo y desarrollo de las pollitas de reemplazo, aunque las necesidades de este mineral pueden estar sobrevaloradas. Se realizó un experimento con 750 pollas de la lí­nea Hy-line W-36, para evaluar los efectos de niveles de fósforo disponible aparente (Pda) durante las etapas de iniciación (1 dí­a a 6 semanas), crecimiento (7 a 12 semanas), desarrollo (13 a 18 semanas) y de inicio a pico de postura. Las caracterí­sticas estudiadas fueron: peso vivo (PV), consumo de alimento (CA), porcentaje de fósforo total en excretas y tibias (PTE y PT), resistencia a ruptura de tibias (RR), masa de huevo (MH) y gravedad especí­fica (GE). El nivel de Pda no afectó (P>0.05) el CA, PTE, PT, RR y MH en las etapas estudiadas. Hubo diferencias (P0.05), mientras que los niveles óptimos biológicos para PV en crecimiento fueron con 0.28 % y desarrollo 0.26 %. Se concluye que las necesidades de fósforo disponible aparente pueden ser menores a lo sugerido por el NRC (1994), durante las etapas y caracterí­sticas medidas, sin afectar la condición corporal y mineralización ósea de las aves

A multifactorial anti-cachectic approach for cancer cachexia in a rat model undergoing chemotherapy

Background: The effectiveness of drugs aimed at counteracting cancer cachexia is generally tested in pre-clinical rodent models, where only the tumour-induced alterations are taken into account, excluding the co-presence of anti-tumour molecules that could worsen the scenario and/or interfere with the treatment. Methods: The aim of the present investigation has been to assess the efficacy of a multifactorial treatment, including formoterol and megestrol acetate, in cachectic tumour-bearing rats (Yoshida AH-130, a highly cachectic tumour) undergoing chemotherapy (sorafenib). Results: Treatment of cachectic tumour-bearing rats with sorafenib (90 mg/kg) causes an important decrease in tumour cell content due to both reduced cell proliferation and increased apoptosis. As a consequence, animal survival significantly improves, while cachexia occurrence persists. Multi-factorial treatment using both formoterol and megestrol acetate is highly effective in preventing muscle wasting and has more powerful effects than the single formoterol administration. In addition, both physical activity and grip strength are significantly improved as compared with the untreated tumour-bearing animals. The effects of the multi-factorial treatment include increased food intake (likely due to megestrol acetate) and decreased protein degradation, as shown by the reduced expression of genes associated with both proteasome and calpain proteolytic systems. Conclusions: The combination of the two drugs proved to be a promising strategy for treating cancer cachexia in a pre-clinical setting that better resembles the human condition, thus providing a strong rationale for the use of such combination in clinical trials involving cachectic cancer patients

Neurocognitive outcomes in neurofibromatosis clinical trials

Neurofibromatosis type 1 (NF1) is associated with neurocognitive deficits that can impact everyday functioning of children, adolescents, and adults with this disease. However, there is little agreement regarding measures to use as cognitive endpoints in clinical trials. This article describes the work of the Neurocognitive Committee of the Response Evaluation in Neurofibromatosis and Schwannomatosis (REiNS) International Collaboration. The goal of this committee is to identify standardized and specific cognitive assessment tools for use in NF clinical trials. The committee first identified cognitive domains relevant to NF1 and prioritized attention as the first domain of focus given prior and current trends in NF1 cognitive clinical trials. Performance measures and behavioral rating questionnaires of attention were reviewed by the group using established criteria to assess patient characteristics, psychometric properties, and feasibility. The highest rated tests underwent side-by-side comparison. The Digit Span subtest from the Wechsler scales was given the highest ratings of the performance measures due to its good psychometrics, feasibility, utility across a wide age range, and extensive use in previous research. The Conners scales achieved the highest ratings of the behavioral questionnaires for similar reasons. Future articles will focus on other cognitive domains, with the ultimate goal of achieving agreement for cognitive endpoints that can be used across NF clinical trials

A system for traffic violation detection

This paper describes the framework and components of an experimental platform for an advanced driver assistance system (ADAS) aimed at providing drivers with a feedback about traffic violations they have committed during their driving. The system is able to detect some specific traffic violations, record data associated to these faults in a local data-base, and also allow visualization of the spatial and temporal information of these traffic violations in a geographical map using the standard Google Earth tool. The test-bed is mainly composed of two parts: a computer vision subsystem for traffic sign detection and recognition which operates during both day and nighttime, and an event data recorder (EDR) for recording data related to some specific traffic violations. The paper covers firstly the description of the hardware architecture and then presents the policies used for handling traffic violations
