NEW FINDINGS: What is the central question of this study? Does the link between cardiorespiratory fitness and gut microbiota diversity persist after adjusting for the potential effects of %body fat and activity-related energy expenditure (AEE)? What is the main finding and its importance? This is the first study to examine the link between cardiorespiratory fitness and gut microbiota diversity while accounting for the underlying effects of %body fat and free-living AEE. Results from the present work suggest cardiorespiratory fitness, not physical activity, is a superior correlate of gut microbiota diversity among post-primary treatment, non-metastatic breast cancer survivors...

Although running shoes alter foot-ground reaction forces, particularly during impact, how they do so is incompletely understood. Here, we hypothesized that footwear effects on running ground reaction force-time patterns can be accurately predicted from the motion of two components of the body's mass ( mb ): the contacting lower-limb ( m1 =0.08• mb ) and the remainder ( m2 =0.92• mb ). Simultaneous motion and vertical ground reaction force-time data were acquired at 1,000 Hz from eight uninstructed subjects running on a force-instrumented treadmill at 4...

The proprioceptive sense provides somatosensory information about positions of parts of the body, information that is essential for guiding behavior and monitoring the body. Few studies have investigated the perceptual localization of individual fingers, despite their importance for tactile exploration and fine manipulation. We present two experiments assessing the performance of proprioceptive localization of multiple fingers, either alone or in combination with visual cues. In the first experiment, we used a virtual reality paradigm to assess localization of multiple fingers...

This study explored the factor structure of four subscales from the Physical Self-Description Questionnaire-Short Form (PSDQ-S). Associations between subscales and personal and medical factors were also examined. The analytic sample consisted of 89 survivors of adolescent and young adult cancer (Mage at time of study  = 32.96 ± 4.37 years; Mage at diagnosis  = 31.16 ± 4.84 years; 75.3% female). Confirmatory factor analysis suggested a reasonable fit to the data, indicating that the PSDQ-S subscales examined could be used in future investigations with this population [χ2 (38) = 46...

Recent advances in immunology have extended into the mesothelioma field. To date, only Japan has given regulatory approval to salvage nivolumab in chemo-refractory mesothelioma patients. The USA has included in the NCCN guidelines that pembrolizumab (in programmed death ligand 1 (PD-L1) immunohistochemistry (IHC)-positive patients) and nivolumab with or without ipilimumab (whatever the PD-L1 status is) are accepted salvage therapies. Based on the growing body of literature, it is anticipated that checkpoint inhibitors will receive regulatory approval in the USA and Europe soon for salvage therapy...

Although the remaining nerve tissue can regenerate and partly restore erectile function when the cavernous nerve is compressed/severed and function lost, the limited regenerative ability of these nerve tissues often fails to meet clinical needs. Adipose-derived stem cells are easy to obtain and culture, and can differentiate into neural cells. Their proliferation rate is easy to control and they may be used to help restore injured cavernous nerve function. Sprague-Dawley male rats (n = 45) were equally randomized into three groups: fifteen rats as a sham-operated group, fifteen rats as a bilateral nerve crush (BINC) group (with no further intervention), fifteen rats as a BINC with intracavernous injection of one million neural-like cells from adipose-derived stem cells (NAS) (BINC + NAS) group...

Regularly eating breakfast and meals with family has important health implications for youth. However, the association between eating breakfast and family meals regularly with body image has not been explored. Utilizing the 2009-2010 World Health Organization's Health Behavior in School-Aged Children U.S. survey (N = 12,642), we sought to begin this conversation. Our findings suggest that eating breakfast and meals with parents more regularly may be related to more positive body image. This cross-sectional glance suggests that policies and programs that encourage youth and families to regularly eat breakfast and family meals may also encourage better body image among youth...

Ouabain, a cardiotonic steroid, was used for the treatment of heart failure and atrial fibrillation and induces cancer cell apoptosis in many human cancer cells including human leukemia cells. However, there are no reports to show the effects on immune responses in a leukemia mouse model. In this study, WEHI-3 cell generated leukemia mice were developed and treated by oral ouabain at 0, 0.75, 1.5, and 3 mg/kg for 15 days. Results indicated that ouabain did not affect body appearance, but decreased liver and spleen weights, B- and T-cell proliferation at all three doses treatment and increased CD19 cells at 3...

Lactoferrin (LF) is an Fe3+ -binding glycoprotein first recognized in milk and then in other epithelial secretions and barrier body fluids to which many different functions have been attributed to LF, including protection from iron-induced lipid peroxidation, immunomodulation, cell growth regulation, DNA and RNA binding, as well as transcriptional activation, еtс. The polyfunctional physiological role of LF is still unclear, but it has been suggested to be responsible for primary defense against microbial and viral infections...

Research into the Dualistic Model of Passion (DMP) has suggested that a harmonious passion for an activity is related to more positive outcomes (e.g., higher well-being and satisfaction with life), and an obsessive passion for an activity is related to negative and less adaptive outcomes (e.g., lower self-esteem and burnout; 37, 40, 43). The current study demonstrated differences between passion types (i.e., harmonious passion, obsessive passion, no passion) in terms of physical fitness, risk of exercise addiction, frequency of exercise, and perceptions of exercise...

Hypertension is a major health concern throughout the United States and is a major cause of cardiovascular disease. The purpose of this study was to compare the responses of Tai Chi and walking on measures of central and peripheral cardiac mechanisms when controlling for exercise intensity. Fifteen hypertensive subjects (2 males, 13 females; age = 20.7 ± 3.77 years; body fat = 24.26 ± 10.27%) participated in Tai Chi (TC) and walking (WK) for 30 minutes on non-consecutive days. Central systolic (CSBP) and diastolic blood pressure (CDBP), augmentation index (Alx), pulse pressure (PP), heart rate (HR), and brachial systolic (BSBP) and diastolic blood pressure (BDBP) were measured prior to exercise and following exercise every 10 minutes for a total of 60 minutes in a seated position...
