The ability to create power is an important variable for athletic success. No study to date has compared peak power output (PPO) fatigue across multiple sets and with different loads with the bench throw. This study aimed to begin the process of establishing empirical upper body power training guidelines for moderately strong athletes by determining how load (30%, 45%, 60% 1RM) affects PPO (Watts) dropoff during 3 sets of 10 repetitions of the bench throw. 10 resistance-trained male volunteers ((mean ± SD): age 20...

BACKGROUND: The conventional approach during orthognathic surgery for cleft-related deformities has largely focused on restoration of maxilla retrusion, using the maxillary advancement as a standard treatment objective. However, we thought the maxillary vertical shortening and deficient incisor show could be the additional key elements of cleft-related deformities. Although slight vertical lengthening can be obtained with only maxillary advancement, it would not be enough to obtain satisfactory aesthetical results in terms of the anterior facial height...

Human-machine haptic interaction is typically detected by variations in friction, roughness, hardness, and temperature, which combines to create sensation of surface texture change. Most of the current technologies work to simulate changes in tactile perception (via electrostatic, lateral force fields, vibration motors, etc.) without creating actual topographical transformations. This makes it challenging to provide localized feedback. Here, a new concept for on-demand surface texture augmentation that is capable of physically forming local topographic features in any predesigned pattern is demonstrated...

Mammographic % density, the proportion of fibroglandular tissue in the breast, is a strong risk factor for breast cancer, but its determinants in young women are unknown. We examined associations between magnetic resonance imaging (MRI) breast-tissue composition at age 21 years and prospectively-collected measures of body size and composition from birth to early adulthood, and markers of puberty (all standardized), in a sample of 500 nulliparous women from a pre-birth cohort of children born in Avon, England, in 1991-1992 and followed up to 2011-2014...

Children with acute and chronic malnutrition are at increased risk of morbidity and mortality following a diarrheal episode. To compare diarrheal disease severity and pathogen prevalence among children with and without acute and chronic malnutrition, we conducted a cross-sectional study of human immunodeficiency virus-uninfected Kenyan children aged 6-59 months, who presented with acute diarrhea. Children underwent clinical and anthropometric assessments and provided stool for bacterial and protozoal pathogen detection...

CONTEXT: Following a baseball pitching bout, changes can occur to glenohumeral range of motion that could be linked to injury. These effects are in part due to the posterior shoulder's eccentric muscle activity, which can disrupt muscle contractile elements and lead to changes in muscle cross sectional area (CSA), as measured by ultrasound. OBJECTIVE: To assess changes in muscle CSA, and range of motion immediately before and after pitching, and days 1-5 following pitching...

The constantly rising percentage of the elderly (60+), who are particularly at risk of the dangerous consequence of falls, results not only in the loss of independence in daily life, but also in a serious threat to health and life. Therefore, many authors emphasize the necessity of conducting prophylaxis and prevention among senior citizens. The most important aspect of fall prophylaxis is care about the optimum level of agility. Exercise should focus on increasing muscular strength, balance and dexterity. The aim of the present study is to determine the relationship between functional fitness and the risk for falls of older people in the light of maintaining physical independence...

There is sex-difference in humans as regards aerobic efficiency, physical strength and endurance and the sex difference is greatly dependent upon differential concentration of testosterone during different phases of growth and development including the intrauterine phase or prenatal growth. Second-to-fourth digit lengths ratio (2D:4D) is an putative indicator of prenatal testosterone exposure. Lower 2D:4D indicates higher prenatal testosterone exposure and vice versa. Males generally have lower 2D:4D than females...

Skeletal muscle loss, commonly known as sarcopenia, is highly prevalent and prognostic of adverse outcomes in oncology. However, there is limited information on adults with early breast cancer and examination of other skeletal muscle indices, despite the potential prognostic importance. This study characterizes and examines age-related changes in body composition of adults with early breast cancer and describes the creation of a novel integrated muscle measure. Female patients diagnosed with stage I-III breast cancer with abdominal computerized tomography (CT) scans within 12 weeks from diagnosis were identified from local tumor registry (N = 241)...

Small-angle neutron scattering has been used to probe the interfacial structure of foams stabilised by small molecule surfactants at concentrations well below their critical micelle concentration. The data for wet foams showed a pronounced Q(-4) dependence at low Q and noticeable inflexions over the mid Q range. These features were found to be dependent on the surfactant structure (mainly the alkyl chain length) with various inflexions across the measured Q range as a function of the chain length but independent of factors such as concentration and foam age/height...

Tungsten oxide cluster anions (WO3)3(-) produced from a magnetron source were soft-landed on highly oriented pyrolytic graphite (HOPG) surfaces at different temperatures, and the structures formed upon deposition were analyzed using ex situ atomic force microscopy. Under liquid nitrogen cooling conditions of 100 K, the clusters form small branched nanostructures extending over a few nanometers with a height not exceeding 1 nm. At 673 K, nanowires approximately 100 nm long and less than 10 nm in diameter are observed...

Crossbar arrays (CBA) with resistive random access memory (ReRAM) constitute an established architecture for high-density memory. However, sneak paths via unselected cells increase the total power consumption of these devices, and limit the array size. To eliminate such sneak path problems, we propose a Ti/GaOx/NbOx/Pt structure with self-rectifying resistive-switching (RS) behavior. In this structure, to reduce the operating voltage, we used a Ti/GaOxstack to increase the number of trap sites in the RS GaOx layer, through interfacial reactions between the Ti and GaOx layers...

Functional tricuspid regurgitation is a significant source of morbidity and mortality in the US. Furthermore, treatment of functional tricuspid regurgitation is suboptimal with significant recurrence rates, which may, at least in part, be due to our limited knowledge of the relationship between valvular shape and function. Here we study the dynamics of the healthy in vivo ovine tricuspid annulus to improve our understanding of normal annular deformations throughout the cardiac cycle. To this end, we determine both clinical as well as engineering metrics of in vivo annular dynamics based on sonomicrometry crystals surgically attached to the annulus...
