    The objective of this report is to characterize the associations between age and semen quality among healthy active men after controlling for identified covariates. Ninety-seven healthy, nonsmoking men between 22 and 80 years without known fertility problems who worked for or retired from a large research laboratory. There was a gradual decrease in all semen parameters from 22-80 years of age. After adjusting for covariates, volume decreased 0.03 ml per year (p = 0.001); sperm concentration decreased 2.5% per year (p = 0.005); total count decreased 3.6% per year of age (p < 0.001); motility decreased 0.7% per year (P < 0.001); progressive motility decreased 3.1% per year (p < 0.001); and total progressively motile sperm decreased 4.8% per year (p < 0.001). In a group of healthy active men, semen volume, sperm concentration, total sperm count, and sperm motility decrease continuously between 22-80 years of age, with no evidence of a threshold.

    Muscle strength can define the general muscular fitness (MF) measurable through hand-grip strength (HG), which is a factor that relates to the health of people of different ages. In this study we evaluated the muscle strength together with a bioimpedance electric analysis in 223 healthy Colombian adult subjects. The bioelectrical impedance vector analysis (BIVA) was conducted to determine the resistance (R), reactance (Xc) and phase angle (PhA). We classified the subjects into three groups (for tertiles), obtaining lower values of R and Xc in subjects with lower HG, plus a high correlation between PhA and HG. An increase in the level of PhA is associated with a high level of MF in a sample of healthy Latin American adult men. The BIVA's parameters and PhA are a potentially effective preventive measure to be integrated into routine screening in the clinical setting. PMID:27384579

    Sex hormones impact reward processing, which is dysfunctional in schizophrenia; however, the degree to which testosterone levels relate to reward-related brain activity in healthy men and the extent to which this relationship may be altered in men with schizophrenia has not been determined. We used functional magnetic resonance imaging (fMRI) to measure neural responses in the striatum during reward prediction-errors and hormone assays to measure testosterone and prolactin in serum. To determine if testosterone can have a direct effect on dopamine neurons, we also localized and measured androgen receptors in human midbrain with immunohistochemistry and quantitative PCR. We found correlations between testosterone and prediction-error related activity in the ventral striatum of healthy men, but not in men with schizophrenia, such that testosterone increased the size of positive and negative prediction-error related activity in a valence-specific manner. We also identified midbrain dopamine neurons that were androgen receptor immunoreactive, and found that androgen receptor (AR) mRNA was positively correlated with tyrosine hydroxylase (TH) mRNA in human male substantia nigra. The results suggest that sex steroid receptors can potentially influence midbrain dopamine biosynthesis, and higher levels of serum testosterone are linked to better discrimination of motivationally-relevant signals in the ventral striatum, putatively by modulation of the dopamine biosynthesis pathway via AR ligand binding. However, the normal relationship between serum testosterone and ventral striatum activity during reward learning appears to be disrupted in schizophrenia. PMID:26232868

    Aim: To determine the effect of sildenafil citrate on the nocturnal penile erections (I.e. Time to onset, the duration of erection, and the interval between first and second erections) of healthy young men. Methods: Twenty-two potent men, 23-29 years old, were recruited for the study. All subjects completed three sessions over consecutive nights using the RigiScan monitoring device (Dacomed, Minneapolis, USA). After a first night of adaptation, night 2 records were their baseline values, and on night 3 they received 100 mg of sildenafil citrate. Statistical comparisons were done between the second and third night data. Results: The mean time to onset of the first erection with sildenafil citrate was (34 ± 18) min, whereas it was (74 ± 24) min (P < 0.001) without sildenafil citrate. The number of erections observed during the first 5 h after sildenafil citrate medication was 3.6 ± 0.5 in contrast to 2.4 ± 0.5 with no medication (P = 0.001). The interval between first and second erections was shorter with sildenafil citrate: (52 ± 26) min vs.(85 ± 34) min (P = 0.01). The duration of the last erection was statistically significantly longer with the sildenafil citrate: (64 ± 33) min vs. (42 ± 28) min (P < 0.01). Conclusion: Healthy young men achieved erection within 34 min after sildenafil citrate administration, which is shorter than the 1 h interval proposed by the manufacturer. The interval between the first and second erections was shorter and the duration of the last nocturnal erection was longer.

    Background The morbidity and mortality of prostate cancer have been increasing rapidly in recent China. There were few studies investigating prostate-specific antigen (PSA) values ranges in the healthy Chinese population. We performed this study to determine the distribution of serum PSA in a large healthy Chinese population.Methods From January 2001 to May 2008, 11 150 healthy Chinese men aged 30-79 years came to our hospital for routine health check-up. All subjects without a previous diagnosis of prostate cancer, a history of prostate surgery, or urogenital tract infection were proposed to undergo systematic serum PSA measurement and digital rectal examination (DRE). Men with normal DRE and PSA ≤4.0 ng/ml and those PSA >4.0 ng/ml or abnormal DRE but without adverse findings on prostate biopsy were included (n=9358). Age and serum PSA concentration were recorded and correlated through Logistic regression analysis.Results The 95th percentile serum PSA concentration was 1.89 ng/ml for men aged 30 to 39 years, 2.19 ng/ml for men aged 40 to 49 years, 2.88 ng/ml for men aged 50 to 59 years, 4.42 rng/ml for men aged 60 to 69 years, and 6.52 ng/ml for men aged 70 to 79 years. The serum PSA concentration correlated with age (P <0.0001) with an annual increase of 0.97% for men in 40 years, 1.58% for men in 50 years, 3.04% for men in 60 years, and 3.99% for men in 70 years.Conclusions The serum PSA level correlates directly with age in Chinese men older than 40 years, not in Chinese men younger than 40 years old. Chinese men have lower PSA level compared with white men above 60 years of age, not in those under 60 years of age.

    We hypothesized that lower proportion of serum phospholipid docosahexaenoic acid (DHA) is inversely associated with increased cardiovascular risk and vascular function in metabolically healthy men. To elucidate it, we first compared serum phospholipid free fatty acid (FA) compositions and cardiovascular risk parameters between healthy men (n = 499) and male patients with coronary artery disease (CAD, n = 111) (30-69 years) without metabolic syndrome, and then further-analyzed the association of serum phospholipid DHA composition with arterial stiffness expressed by brachial-ankle pulse wave velocity (ba-PWV) in metabolically healthy men. Basic parameters, lipid profiles, fasting glycemic status, adiponectin, high sensitivity C-reactive protein (hs-CRP) and LDL particle size, and serum phospholipid FA compositions were significantly different between the two subject groups. Serum phospholipid DHA was highly correlated with most of long-chain FAs. Metabolically healthy men were subdivided into tertile groups according to serum phospholipid DHA proportion: lower ( 3.235%). Fasting glucose, insulin resistance, hs-CRP and ba-PWVs were significantly higher and adiponectin and LDL particle size were significantly lower in the lower-DHA group than the higher-DHA group after adjusted for confounding factors. In metabolically healthy men, multiple stepwise regression analysis revealed that serum phospholipid DHA mainly contributed to arterial stiffness (β′-coefficients = -0.127, p = 0.006) together with age, systolic blood pressure, triglyceride (r = 0.548, p = 0.023). Lower proportion of serum phospholipid DHA was associated with increased cardiovascular risk and arterial stiffness in metabolically healthy men. It suggests that maintaining higher proportion of serum phospholipid DHA may be beneficial for reducing cardiovascular risk including arterial stiffness in metabolically healthy men. PMID:27482523

    Full Text Available Introduction: The present research investigated the effects of two different types of music on cardiovascular responses in essential hypertensive men in comparison with healthy men based on introversion and extraversion. Methods: One hundred and thirteen hypertensive men referred to Madani Heart Hospital in Tabriz completed the NEO-FFI Questionnaire and after obtaining acceptable scores were classified in four groups: introvert patients, extravert patients, introvert healthy subjects, and extravert healthy subjects (each group with 25 samples with age range 31-50. Baseline blood pressure and heart rate of each subject was recorded without any stimulus. Then subjects were exposed to slow-beat music and blood pressure and heart rate were recorded. After15 minute break, and a little cognitive task for distraction, subjects were exposed to fast-beat music and blood pressure and heart rate were recorded again. Results: Multivariate analysis of covariance (MANCOVA test showed that extravert patient subjects obtained greater reduction in systolic blood pressure and heart rate after presenting slow-beat music compared with introvert patients (P= 0.035, and P= 0.033 respectively. And extravert healthy subjects obtained greater reduction in heart rate after presenting slow-beat music compared with introvert healthy subjects (P= 0.036. However, there are no significant differences between introvert and extravert groups in systolic and diastolic blood pressure and heart rate after presenting fast-beat music. Conclusion: Based on our results, introvert subjects experience negative emotions more than extravert subjects and negative emotions cause less change in blood pressure in these subjects compared with extravert subjects.

    Clinically healthy male executives who participate in a long-term physical conditioning program have demonstrated cardiac arrhythmia during and after periodic ergometric testing at submaximal and maximal levels. In 1,385 tests on 248 subjects, it was found that 34% of subjects demonstrated an arrhythmia at some time and 13% of subjects developed arrhythmia on more than one test. Premature systoles of ventricular origin were most common, but premature systoles of atrial origin, premature systoles of junctional origin, paroxysmal atrial tachycardia, atrioventricular block, wandering pacemaker, and pre-excitation were also seen. Careful post-test monitoring and pulse rate regulated training sessions are suggested for such programs.

    Empathy is a core prerequisite for human social behavior. Relatively, little is known about how empathy is influenced by social stress and its associated neuroendocrine alterations. The current study was designed to test the impact of acute stress on emotional and cognitive empathy. Healthy male participants were exposed to a psychosocial laboratory stressor (trier social stress test, (TSST)) or a well-matched control condition (Placebo-TSST). Afterwards they participated in an empathy test measuring emotional and cognitive empathy (multifaceted empathy test, (MET)). Stress exposure caused an increase in negative affect, a rise in salivary alpha amylase and a rise in cortisol. Participants exposed to stress reported more emotional empathy in response to pictures displaying both positive and negative emotional social scenes. Cognitive empathy (emotion recognition) in contrast did not differ between the stress and the control group. The current findings provide initial evidence for enhanced emotional empathy after acute psychosocial stress.

    Full Text Available The purpose of this study was to determine the aerobic training intensity from the maximal and submaximal running exercise in 21 untrained adult men. To accomplish this, we evaluated the relationship between physiological (oxygen intake and heart rate and physical parameters (running speed of training intensity, and determined the training intensity at the submaximal exercise. Oxygen intake and heart rate were measured by a treadmill test. The maximal oxygen intake (VO2 max, and the aerobic threshold (AerT and anaerobic threshold (AT were measured to determine respiratory gas exchange. Running capacity was measured by a 12-min running and treadmill test. For the maximal exercise, there was a significant correlation (r = 0.88, P < 0.01 between VO2 max and 12-min running distance (speed. In addition, the oxygen intake and heart rate at AerT and AT in the submaximal exercise were linearly correlated with running speed. Three levels of training intensity at the submaximal exercise were termed: light, moderate, and heavy. Since AerT was the lower limit intensity and AT was the upper limit, we took the middle of their values as the moderate intensity. The end point for the determination of the training intensity at the submaximal exercise was estimated to be 85% VO2 max and 180 beats.min-1.

    There is increasing evidence of gender-related differences in gastric emptying. The purpose of this study was first, to confirm the difference in gastric emptying for both solid and liquid test meals between healthy men and women, and secondly, to investigate the origin of this difference by studying regional gastric emptying and antral motility. A standard gastric emptying test with additional compartmental (proximal and distal) evaluation and dynamic imaging of the antrum was performed in 20 healthy women studied during the first 10 days of the menstrual cycle, and in 31 healthy age-matched men. In concordance with previous reports, women had a longer half-emptying time for solids as compared to men (86.2{+-}5.1 vs 52.2{+-}2.9 min, P<0.05). In our observations this seemed to be related to a significantly prolonged lag phase and a significant decrease in terminal slope. Dynamical antral scintigraphy did not show a significant difference. The distribution of the test meal within the stomach (proximal vs distal) showed more early proximal retention in women as compared to men. The terminal slope of the distal somach was significantly lower in women. We did not observe a significant difference in gastric emptying of the liquid test meal between men and women. Gastric emptying of solids is significantly slower in healthy women as compared to men. These findings emphasise the importance of using different normal values for clinical and research purposes in gastric emptying scintigraphy in men and women. The difference could not be explained by antral motility alone. Increased proximal retention and a lower terminal emptying rate in women are observations to be further investigated. (orig.)

    Recruiting a scientifically sound cohort of young men who have sex with men (YMSM) is an enduring research challenge. The few cohort studies that have been conducted to date on YMSM have relied on non-probability sampling methods to construct their cohorts. While these studies have provided valuable information about HIV risk behaviors among YMSM, their generalizability to broader YMSM populations is limited.In this paper the authors describe a venue-based sampling methodology used to recruit a large and diverse cohort of YMSM from public venues in Los Angeles County. Venue-based sampling is a multi-stage, probability sampling design that uses standard outreach techniques and standard survey methods to systematically enumerate, sample, and survey hard-to-reach populations. The study design allowed the authors to estimate individual, familial and interpersonal psychosocial factors associated with HIV risk and health seeking behaviors for a cohort of YMSM with known properties. Study participants completed an extensive baseline survey and over a two year period will complete four follow-up surveys at six-month intervals. The baseline survey was administered in both English and Spanish.

The MetS group was further divided according to fasting triglycerides (TG into TG ≥ 150 [MetS+TG, (n = 22] or The postprandial response was significantly higher in MetS compared to HTN and healthy men [AUC (SD in mg/dl/h; 2534 ± 1016 vs. 1620 ± 494 and 1019 ± 280, respectively, p ≤ 0.001]. The TG levels were increased significantly in MetS+TG compared to MetS-TG subjects at 4 (p = 0.022, 6 (p Conclusion Fasting TG concentration is the main determinant of postprandial lipemia. However, an exaggeration of TG postprandialy was found in normotriglyceridemic MetS and HTN compared to healthy subjects. This suggests that intervention to lower fasting TG levels should be recommended in MetS subjects.

    Whether fat is beneficial or detrimental to bones is still controversial, which may be due to inequivalence of the fat mass. Our objective is to define the effect of body fat and its distribution on bone quality in healthy Chinese men. A total of 228 men, aged from 38 to 89 years, were recruited. BMD, trabecular bone score (TBS), and body fat distribution were measured by dual-energy X-ray absorptiometry. Subcutaneous and visceral fat were assessed by MRI. In the Pearson correlation analysis,...

    Full Text Available Objective. The purpose of the study was to assess total antioxidant capacity (TAC of blood serum in relation with habitual leisure time physical activity (LTPA and aerobic capacity in a group of 90 men with coronary heart disease (CHD aged 34.8–77.0 years and in 90 age-matched peers without CHD. Methods. Two spectrophotometric methods were applied to assess TAC: Ferric Reducing Ability of Serum (TAC-FRAS and 2.2-diphenyl-1-picryl-hydrazyl (TAC-DPPH tests. Aerobic capacity was expressed as physical working capacity at 85% of the maximal heart rate (PWC85%HRmax. Results. CHD patients had higher values of TACFRAS (1.37±0.28 versus 1.27±0.23 mmol FeCl2·L−1; P<0.05 but there were no group differences for TAC-DPPH and for uric acid (UA. Negative correlation was found between LTPA (also when calculated per kg of body mass and TAC-DPPH in CHD patients. In CHD patients, TAC-FRAS and UA were lower in subjects with higher aerobic capacity expressed as PWC85%HRmax/kg. Those associations were not found in healthy men. Conclusions. We conclude that TAC of blood serum is moderately adversely related to LTPA and aerobic capacity in patients with CHD. UA, as the main determinant of serum TAC, may be partially responsible for those associations.

    To examine whether age differentially modifies the physiological response to exercise in men and women, we performed gated radionuclide ventriculography with measurement of left ventricular volumes at rest and during peak upright cycle exercise in 200 rigorously screened healthy sedentary volunteers (121 men and 79 women) aged 22-86 yr from the Baltimore Longitudinal Study of Aging. At rest in the sitting position, age-associated declines in heart rate (HR) and increases in systolic blood pressure occurred in both sexes. Whereas resting cardiac index (CI) and total systemic vascular resistance (TSVR) in men did not vary with age, in women resting CI decreased 16% and TSVR increased 46% over the six-decade age span. Men, but not women, demonstrated an age-associated increase of approximately 20% in sitting end-diastolic volume index (EDVI), end-systolic volume index (ESVI), and stroke volume index over this age span. Peak cycle work rate declined with age approximately 40% in both sexes, but at any age it was greater in men than in women even after normalization for body weight. At peak effort, ejection fraction (EF), HR, and CI were reduced similarly with age while ESVI and TSVR were increased in both sexes; EDVI increased 35% with age and stroke work index (SWI) rose 19% in men, but neither was related to age in women; and stroke volume index did not vary with age in either sex. When hemodynamics were expressed as the change from rest to peak effort as an index of cardiovascular reserve function, both sexes demonstrated age-associated increases in EDVI and ESVI and reductions in EF, HR, and CI. However, the exercise-induced reduction in ESVI and the increases in EF, CI, and SWI from rest were greater in men than in women. Thus, age and gender each have a significant impact on the cardiac response to exhaustive upright cycle exercise. PMID:7775334

    Full Text Available Abstract Background Overall the physical health of Indigenous men is among the worst in Australia. Research has indicated that modifiable lifestyle factors, such as poor nutrition and physical inactivity, appear to contribute strongly to these poor health conditions. To effectively develop and implement strategies to improve the health of Australia's Indigenous peoples, a greater understanding is needed of how Indigenous men perceive health, and how they view and care for their bodies. Further, a more systematic understanding of how sociocultural factors affect their health attitudes and behaviours is needed. This article presents the study protocol of a community-based investigation into the factors surrounding the health and body image of Indigenous Australian men. Methods and design The study will be conducted in a collaborative manner with Indigenous Australian men using a participatory action research framework. Men will be recruited from three locations around Australia (metropolitan, regional, and rural and interviewed to understand their experiences and perspectives on a number of issues related to health and health behaviour. The information that is collected will be analysed using modified grounded theory and thematic analysis. The results will then be used to develop and implement community events in each location to provide feedback on the findings to the community, promote health enhancing strategies, and determine future action and collaboration. Discussion This study will explore both risk and protective factors that affect the health of Indigenous Australian men. This knowledge will be disseminated to the wider Indigenous community and can be used to inform future health promotion strategies. The expected outcome of this study is therefore an increased understanding of health and health change in Indigenous Australian men, the development of strategies that promote healthy eating and positive patterns of physical activity and, in

    Full Text Available AIM: Varicocele is characterized by abnormal tortuosity and dilatation of the veins of the pampiniform plexus within the spermatic cord and is one of the causes related to male infertility. This study aimed to investigate the correlation between varicocele and somatometric parameters. We also aimed to determine prevalence and treatment ratio of this disorder among healthy young Turkish men. MATERIALS AND METHODS: A total of 2061 young men aged from 19 to 34 years was enrolled and cross sectionally evaluated for status of varicocele. Body mass index was calculated. Patients were categorized as normal weight, overweight and obese using by National Institutes of Health criteria. Patients underwent physical examinations for the presence and grade of varicocele. If the varicocele was found and previously submitted to different treatment modalities, the age of treatment and outcomes were recorded. RESULTS: Varicocele was present in 498 men (24.2%. The mean age of the participants was 22.7 ± 1.8 years, and the median BMI was 22.8 ± 2.0 kg/m². There were no significant differences in age, height, weight and BMI among the patients with different grades of varicocele (p > 0.05. Although no significant difference was found in varicocele prevalence between normal weight and over-weight participants (p > 0.05, obese participants had significantly lower varicocele prevalence compared with normal or over weight participants (p = 0.006. A total of 49 men had scrotal pain and the treatment ratio was only 2.8%. CONCLUSION: Prevalence of varicocele was found in about 24% of healthy young Turkish population. Participants with varicocele had significantly lower BMI values compared with those without varicocele. Our findings supported the hypothesis that individuals with a greater BMI may have advantages in relieving the varicocele, but further studies are required to clarify this issue. Additionally treatment ratio was low among young men with varicocele.

    Full Text Available PURPOSE: To provide a large reference material on aerobic fitness and exercise physiology data in a healthy population of Norwegian men and women aged 20-90 years. METHODS: Maximal and sub maximal levels of VO2, heart rate, oxygen pulse, and rating of perceived exertion (Borg scale: 6-20 were measured in 1929 men and 1881 women during treadmill running. RESULTS: The highest VO2max and maximal heart rate among men and women were observed in the youngest age group (20-29 years and was 54.4±8.4 mL·kg(-1·min(-1 and 43.0±7.7 mL·kg(-1·min(-1 (sex differences, p<0.001 and 196±10 beats·min(-1 and 194±9 beats·min(-1 (sex differences, p<0.05, respectively, with a subsequent reduction of approximately 3.5 mL·kg(-1·min(-1 and 6 beats·min(-1 per decade. The highest oxygen pulses were observed in the 3 youngest age groups (20-29 years, 30-39 years, 40-49 years among men and women; 22.3 mL·beat(-1±3.6 and 14.7 mL·beat(-1±2.7 (sex differences, p<0.001, respectively, with no significant difference between these age groups. After the age of 50 we observed an 8% reduction per decade among both sexes. Borg scores appear to give a good estimate of the relative exercise intensity, although observing a slightly different relationship than reported in previous reference material from small populations. CONCLUSION: This is the largest European reference material of objectively measured parameters of aerobic fitness and exercise-physiology in healthy men and women aged 20-90 years, forming the basis for an easily accessible, valid and understandable tool for improved training prescription in healthy men and women.

    We asked if the higher work of breathing (Wb) during exercise in women compared with men is explained by biological sex. We created a statistical model that accounts for both the viscoelastic and the resistive components of the total Wb and independently compares the effects of biological sex. We applied the model to esophageal pressure-derived Wb values obtained during an incremental cycle test to exhaustion. Subjects were healthy men (n = 17) and women (n = 18) with a range of maximal aerobic capacities (V̇o2 max range: men = 40-68 and women = 39-60 ml·kg(-1)·min(-1)). We also calculated the dysanapsis ratio using measures of lung recoil and forced expiratory flow as index of airway caliber. By applying the model we found that the differences in the total Wb during exercise in women are due to a higher resistive Wb rather than viscoelastic Wb. We also found that the higher resistive Wb is independently explained by biological sex. To account for the known effect of lung volumes on the dysanapsis ratio we compared the sexes with an analysis of covariance procedures and found that when vital capacity was accounted for the adjusted mean dysanapsis ratio is statistically lower in women (0.17 vs. 0.25 arbitrary units; P human airways, which result in significant male-female differences in the Wb during exercise in healthy subjects.

    Lipid and lipoprotein response to reduced dietary fat intake was investigated in relation to differences in distribution of LDL subclasses among 105 healthy men consuming high-fat (46%) and low-fat (24%) diets in random order for six weeks each. On high-fat, 87 subjects had predominantly large, buoyant LDL as measured by gradient gel electrophoresis and confirmed by analytic ultracentrifugation (pattern A), while the remainder had primarily smaller, denser LDL (pattern B). On low-fat, 36 men changed from pattern A to B. Compared with the 51 men in the stable A group, men in the stable B group (n = 18) had a three-fold greater reduction in LDL cholesterol and significantly greater reductions in plasma apoB and mass of intermediate (LDL II) and small (LDL III) LDL subtractions measured by analytic ultracentrifugation. In both stable A and change groups, reductions in LDL-cholesterol were not accompanied by reduced plasma apoB, consistent with the observation of a shift in LDL particle mass from larger, lipid-enriched (LDL I and II) to smaller, lipid-depleted (LDL III and IV) subfractions, without significant change in particle number. Genetic and environmental factors influencing LDL subclass distributions thus may also contribute substantially to interindividual variation in response to a low-fat diet.

The obtained finger/palmar dermatoglyphics did not differentiate administrative-territorial local groups of men between the north and the center, south and west (quantitative characteristics; or palmar – between the north and west, north and east, south and west, south and east, north and center. The differences between the administrative and territorial division of dermatoglyphic signs are a reflection of the historical and cultural differences induced by migration, as well as the intensive process of mixing, in addition to the isolation of particular groups.

    Purpose Recently, reports in the mass media have implicated that bicycle riding increases the risk of erectile dysfunction and prostatic diseases. So, we evaluate the impact of bicycle riding on erectile function and lower urinary tract symptoms (LUTS) in healthy general men. Methods From 26 June 2010 to 20 July 2010, we investigate degree of LUTS (voiding and storage symptoms), using International Continence Society-male Questionnaire (ICS-mQ) and erectile function using International Index of Erectile Function-5 Questionnaire (IIEF-5) in 5 work places (personnel of public office, hospital, university, etc.) of which bicycle riding club members were doing active club activities. Respondents, who participated in club activities for 6 months and longer, were classified as the bicycle club (142 men; age, 44.02±8.56). Ones who do not ride bicycles were classified as the control group (83 men; age, 42.13±7.85). People who were having the history of urological and other chronic diseases (diabetes, vascular disease, heart disease, etc) were excluded from both groups. Results Bicycle club is not significantly associated with increased prevalence of LUTS (bicycle club, 2.1 to 57.7% control, 4.8 to 73.5%) and erectile dysfunction (bicycle club, 46.1% control, 55.4%). The total mean score (storage/voiding/erectile function) of bicycle club (13.93±1.95/11.14±3.49/20.46±5.30) were not significantly different from control (14.35±2.49/11.52±3.38/20.40±4.07) (P=0.190 to 0.968). Conclusions These results suggested that bicycle riding as exercise or hobby has no negative effect on LUTS and erectile function in healthy general men, although this research data were limited to the questionnaire analysis.

    Despite the popularity of dietary nitrate supplementation and the growing evidence base of its potential ergogenic and vascular health benefits, there is no direct information about its effects on exercising limb blood flow in humans. We hypothesized that acute dietary nitrate supplementation from beetroot juice would augment the increases in forearm blood flow, as well as the progressive dilation of the brachial artery, during graded handgrip exercise in healthy young men. In a randomized, double-blind, placebo-controlled crossover study, 12 young (22 ± 2 years) healthy men consumed a beetroot juice (140 mL Beet-It Sport, James White Juice Company) that provided 12.9 mmol (0.8 g) of nitrate or placebo (nitrate-depleted Beet-It Sport) on 2 study visits. At 3 h postconsumption, brachial artery diameter, flow, and blood velocity were measured (Doppler ultrasound) at rest and during 6 exercise intensities. Nitrate supplementation raised plasma nitrate (19.5-fold) and nitrite (1.6-fold) concentrations, and lowered resting arterial pulse wave velocity (PWV) versus placebo (all p < 0.05), indicating absorption, conversion, and a biological effect of this supplement. The supplement-associated lowering of PWV was also negatively correlated with plasma nitrite (r = -0.72, p = 0.0127). Despite these systemic effects, nitrate supplementation had no effect on brachial artery diameter, flow, or shear rates at rest (all p ≥ 0.28) or during any exercise workload (all p ≥ 0.18). These findings suggest that acute dietary nitrate supplementation favorably modifies arterial PWV, but does not augment blood flow or brachial artery vasodilation during nonfatiguing forearm exercise in healthy young men.

    Full Text Available Abscess formation after septic arthritis in the sternoclavicular joint is a rare phenomenon in healthy people without immune suppression, intravenous drug abuse, or diabetes. Here we report two cases with formation of abscess in two middle-aged men, with no relevant comorbidities and no obvious sites of infection. The abscesses were both treated surgically with debridement followed by negative pressure wound therapy and antibiotics. The cases differ in diagnostic procedures and delay of diagnosis and broach the issues of handling a rare disease.

    Full Text Available Leptin is involved in the endocrine control of energy expenditure and body weight regulation. Previous studies emphasize a relationship between hypoxic states and leptin concentrations. The aim of this study was to investigate the effects of acute hypoxia on leptin concentrations in healthy subjects. We examined 14 healthy men. Hypoxic conditions were induced by decreasing oxygen saturation to 75% for 30 minutes. Plasma leptin concentrations were determined at baseline, after 3 hours of euglycemic clamping, during hypoxia, and repeatedly the following 2.5 hours thereafter. Our results show an increase of plasma leptin concentrations in the course of 6 hours of hyperinsulinemic-euglycemic clamping which may reflect diurnal rhythmicity. Notwithstanding, there was no difference between levels of leptin in the hypoxic and the normoxic condition (=.2. Since we did not find any significant changes in leptin responses upon hypoxia, plasma leptin levels do not seem to be affected by short hypoxic episodes of moderate degree.

    The recently discovered hormone leptin is primarily secreted by adipose tissue and serves as an internal signal indicating the size of body fat stores. The aim of the present study was to investigate the impact of the dietary fatty acid composition on serum leptin concentrations. Therefore, serum leptin levels were measured by RIA in healthy nonobese men (n = 30) and women (n = 25). First, all participants received a baseline high-fat diet, rich in saturated fat, for 2 wk and were then randomly assigned to one of three high-fat dietary treatments, which contained refined olive oil (rich in monounsaturated fatty acids, n = 19), rapeseed oil [rich in monounsaturated fatty acids and alpha-linolenic acid (18:3n-3), n = 17], or sunflower oil (rich in n-6-polyunsaturated fatty acids, n = 19) as the principal source of fat for 4 wk. On the rapeseed oil diet, serum leptin concentrations increased slightly in men [+0.25 ng/ml, T(9) = -2.778, P = 0.021], but decreased distinctly in women [-4.70 ng/ml, T(6) = 5.083, P = 0.002]. Both the olive oil and the sunflower oil diet did not affect serum leptin concentrations. Thus, it is proposed that serum leptin levels were affected by the high amount of alpha-linolenic acid in rapeseed oil. However, questions remain as to why this diet differently affected serum leptin in men and women.

    The aim of this study was to investigate the relation between endothelial dysfunction and aspirin response in a young healthy population (102 men aged 18-40). Initial concentrations of the NO pathway metabolites (ADMA, l-arginine, SDMA), cardiovascular risk markers, oxidative stress markers (MDA, thiol index), sICAM1, sVCAM1, PAI-1, sE-selectin, sP-selectin, VEGF, thromboxane B2, 6-keto-PGF1α and arachidonate-induced platelet aggregation (to separate aspirin resistant from sensitive group) were measured. Flow-mediated-vasodilation (FMD) was measured before and after intravenous infusion of 16.0 g of l-arginine. Measurements were repeated following aspirin administration (75 mg/24 h) for 4 days. Both groups were homogenous regarding demographic and biochemical characteristics reflecting cardiovascular risk. Aspirin resistant subjects were characterized by lower baseline FMD and higher FMD following aspirin and l-arginine treatment, as compared to aspirin sensitive control. MDA and nitrotyrosine were greater, whereas thiol index was lower in aspirin resistant men. The sICAM1, sVCAM1, PAI-1, sE-selectin, sP-selectin and VEGF levels were similar in the analyzed groups. Thromboxane in aspirin resistant subjects was greater both at baseline and following aspirin therapy. However, a significant decrease following aspirin treatment was present in both groups. Aspirin resistance in young men is associated with endothelial dysfunction, which could be due to oxidative stress resulting from lipid peroxidation. PMID:25697550

    Improving physical function and mobility in a continuously expanding elderly population emerges as a high priority of medicine today. Muscle mass, strength/power, and maximal exercise capacity are major determinants of physical function, and all decline with aging. This contributes to the incidence of frailty and disability observed in older men. Furthermore, it facilitates the accumulation of body fat and development of insulin resistance. Muscle adaptation to exercise is strongly influenced by anabolic endocrine hormones and local load-sensitive autocrine/paracrine growth factors. GH, IGF-I, and testosterone (T) are directly involved in muscle adaptation to exercise because they promote muscle protein synthesis, whereas T and locally expressed IGF-I have been reported to activate muscle stem cells. Although exercise programs improve physical function, in the long-term most older men fail to comply. The GH/IGF-I axis and T levels decline markedly with aging, whereas accumulating evidence supports their indispensable role in maintaining physical function integrity. Several studies have reported that the administration of T improves lean body mass and maximal voluntary strength in healthy older men. On the other hand, most studies have shown that administration of GH alone failed to improve muscle strength despite amelioration of the detrimental somatic changes of aging. Both GH and T are anabolic agents that promote muscle protein synthesis and hypertrophy but work through separate mechanisms, and the combined administration of GH and T, albeit in only a few studies, has resulted in greater efficacy than either hormone alone. Although it is clear that this combined approach is effective, this review concludes that further studies are needed to assess the long-term efficacy and safety of combined hormone replacement therapy in older men before the medical rationale of prescribing hormone replacement therapy for combating the sarcopenia of aging can be established.

  11. ‘BIG, HARD and UP!’ A healthy creed for men to live by?

    Full Text Available The social construction of reality is influenced extensively by the mass media. Commercialised images of masculinity, including discourses to interpret it, are continuously reflected and/or created by sources of mass media, in a myriad of ways. These images are subjectively loaded, but still effectively communicate to us, and even entice and persuade us. It furthermore wields extensive power over men – especially over their self-images, passions, and egos. In this article, dominating images and discourses concerning manhood and male identity – particularly those displayed in men’s health magazines (MHM – were critically examined. This was done through a thematic analysis of 123 issues (spanning more than 10 years of MHM cover pages. The investigation showed that MHM is infused with traditional masculine ideology. Moreover, MHM fails to confront discourses that endorse hegemonic masculinity, for the sake of holistic health. It was suggested that a sober, precautionary, health strategy should challenge men to critically engage with MHM’s reigning creed: ‘big, hard and up’. This creed incites a utilitarian view of sexuality within a culture of performance-driven masculinity, which subsequently fuels anxieties that can lead to unhealthy issues, such as body image dissatisfaction. From a pastoral care perspective, it was asserted that (specifically Christian men need to search for alternative ways to instigate their capacity to experience and facilitate authentic intimacy, in order to work toward the social construction of more balanced and healthy discourses on male identity. Keywords:Masculinity/Masculinities; Men's Health; Male Sexuality; Embodiment; Pastoral Care Perspective

    OBJECTIVE: Low birth weight (LBW), a marker of disturbed fetal growth, is associated with adiposity and increased risk of type 2 diabetes (T2D). The aim of the study was to investigate whether LBW is associated with changes in 24-h energy expenditure (EE) and/or substrate utilization rates......, potentially contributing to the development of adiposity and/or T2D compared to matched control subjects. MATERIALS/METHODS: Forty-six young, healthy men were included in the study; 20 with LBW (= 10th percentile) and 26 control subjects with normal birth weight (NBW) (50th-90th percentile). The subjects were...... oxidation at the expense of reduced glucose oxidation. We speculate that this may be associated with insufficient capability to retain fat in subcutaneous adipose tissue after meals during day time, with an increased rate of nocturnal and morning lipolysis, and potentially with subtle elevations...

    Objective It is still a matter of debate if subtle changes in selenium (Se) status affect thyroid function tests (TFTs) and bone mineral density (BMD). This is particularly relevant for the elderly, whose nutritional status is more vulnerable. Design and Methods We investigated Se status in a cohort of 387 healthy elderly men (median age 77 yrs; inter quartile range 75–80 yrs) in relation to TFTs and BMD. Se status was determined by measuring both plasma selenoprotein P (SePP) and Se. Results The overall Se status in our population was low normal with only 0.5% (2/387) of subjects meeting the criteria for Se deficiency. SePP and Se levels were not associated with thyroid stimulating hormone (TSH), free thyroxine (FT4), thyroxine (T4), triiodothyronine (T3) or reverse triiodothyronine (rT3) levels. The T3/T4 and T3/rT3 ratios, reflecting peripheral metabolism of thyroid hormone, were not associated with Se status either. SePP and Se were positively associated with total BMD and femoral trochanter BMD. Se, but not SePP, was positively associated with femoral neck and ward's BMD. Multivariate linear analyses showed that these associations remain statistically significant in a model including TSH, FT4, body mass index, physical performance score, age, smoking, diabetes mellitus and number of medication use. Conclusion Our study demonstrates that Se status, within the normal European marginally supplied range, is positively associated with BMD in healthy aging men, independent of thyroid function. Thyroid function tests appear unaffected by Se status in this population. PMID:27055238

    Healthful eating and physical activity are important for healthy weight maintenance. The hypothesis for this study was that college-aged men would perceive factors affecting eating and physical activity as both contributing to and inhibiting healthy weight maintenance. The overall objective was to explore how men view weight maintenance in the context of these aspects. Subjects (n = 47, mean age = 20.3 +/- 1.7 years) completed an online survey, including the 51-item Three-Factor Eating Questionnaire, and participated in 1 of 6 focus groups. Three face-to-face and 3 online synchronous groups were conducted using a 15-question discussion guide to identify weight maintenance issues around eating, physical activity, and body perceptions. Weight satisfaction decreased with increase in both dietary restraint and disinhibition. Number of attempts to lose weight was positively associated with BMI (r [44] = .465, P = .01) and dietary restraint (r [44] = .515, P = .01). Findings from both focus group formats were similar. Motivators (sports performance/fitness, self-esteem, attractiveness, long-term health) were similar for eating healthfully and being physically active; however, more motivators to be physically active than to eat healthfully emerged. Enablers for eating healthfully included liking the taste, availability of healthful foods, using food rules to guide intake, having a habit of healthful eating, and internal drive/will. Barriers to healthful eating included fat in dairy foods, fruit and vegetable taste, and quick spoilage. Barriers to being physically active included lack of time/time management, obligations, being lazy, and girlfriends. Results may be used to inform future obesity prevention interventions.

    The trace element selenium (Se) is essential for immune system development and function in animals. However, the exact functions of Se in the human immune system and the achievable health benefits from Se supplementation remain unclear. To test whether an increased intake of dietary Se affects immune function, we conducted a randomized, controlled trial of Se supplementation in healthy free-living men. Forty-two men were administered 300microg of Se a day as high-Se Baker's yeast, or low-Se yeast for 48 weeks. Serum immunoglobulins, differential complete blood counts and lymphocyte sub-populations were measured every 6 weeks. Tests of delayed-type hypersensitivity (DTH) skin responses to mumps, candida, trychophyton, tuberculin-purified protein, and tetanus were performed at baseline and at the end of 48 weeks of treatment. Supplementation increased blood Se concentration by 50%. Surprisingly, consumption of the low-Se yeast induced anergy in DTH skin responses and increased counts of natural killer (NK) cells and T lymphocytes expressing both subunits of the high affinity interleukin-2 receptor (IL2R). DTH skin responses and IL2R+ cells did not change in the high-Se group, suggesting Se supplementation blocked induction of DTH anergy. There were no differences between groups in quality of life indicators, number of days sick, other leukocyte phenotypes, serum immunoglobulins, or complement factors. These results suggest that Se plays a role in immunotolerization, a cell-mediated process involved in many aspects of immune function.

    Whether fat is beneficial or detrimental to bones is still controversial, which may be due to inequivalence of the fat mass. Our objective is to define the effect of body fat and its distribution on bone quality in healthy Chinese men. A total of 228 men, aged from 38 to 89 years, were recruited. BMD, trabecular bone score (TBS), and body fat distribution were measured by dual-energy X-ray absorptiometry. Subcutaneous and visceral fat were assessed by MRI. In the Pearson correlation analysis, lumbar spine BMD exhibited positive associations with total and all regional fat depots, regardless of the fat distribution. However, the correlation disappeared with adjusted covariables of age, BMI, HDL-C, and HbA1c%. TBS was negatively correlated with fat mass. In multiple linear regression models, android fat (and not gynoid, trunk, or limbs fat) showed significant inverse association with TBS (β = -0.611, P android fat and visceral fat, may have negative effects on bone microstructure; whereas body fat mass contributes to BMD through mechanical loading.

    The aim of this study was to determine how rated appetite relates to the amount eaten in a meal in healthy older people. On two study days, 32 healthy older men (n = 16) and women (n = 16) aged 65-85 years, recruited by advertisement, consumed a standardised breakfast and 4 h later were offered lunch from which they could eat freely. Foods eaten at lunch were weighed and energy intake calculated from nutrient composition data. Appetite was assessed at baseline and at 30-min intervals between meals by line ratings of hunger, fullness, nausea and how much could be eaten. The optimum time for correlations both among appetite ratings and between appetite and lunch intake was just before the lunch. Mean coefficients of repeatability (21-38 mm) and correlation coefficients (0.67-0.71) at that point in time were similar to those reported previously in young adults. Thus, in older and well as young adults, the size of a meal is most closely related to rated appetite just before the meal.

    Full Text Available BACKGROUND: Splanchnic hypoperfusion is common in various pathophysiological conditions and often considered to lead to gut dysfunction. While it is known that physiological situations such as physical exercise also result in splanchnic hypoperfusion, the consequences of flow redistribution at the expense of abdominal organs remained to be determined. This study focuses on the effects of splanchnic hypoperfusion on the gut, and the relationship between hypoperfusion, intestinal injury and permeability during physical exercise in healthy men. METHODS AND FINDINGS: Healthy men cycled for 60 minutes at 70% of maximum workload capacity. Splanchnic hypoperfusion was assessed using gastric tonometry. Blood, sampled every 10 minutes, was analyzed for enterocyte damage parameters (intestinal fatty acid binding protein (I-FABP and ileal bile acid binding protein (I-BABP. Changes in intestinal permeability were assessed using sugar probes. Furthermore, liver and renal parameters were assessed. Splanchnic perfusion rapidly decreased during exercise, reflected by increased gap(g-apCO(2 from -0.85±0.15 to 0.85±0.42 kPa (p<0.001. Hypoperfusion increased plasma I-FABP (615±118 vs. 309±46 pg/ml, p<0.001 and I-BABP (14.30±2.20 vs. 5.06±1.27 ng/ml, p<0.001, and hypoperfusion correlated significantly with this small intestinal damage (r(S = 0.59; p<0.001. Last of all, plasma analysis revealed an increase in small intestinal permeability after exercise (p<0.001, which correlated with intestinal injury (r(S = 0.50; p<0.001. Liver parameters, but not renal parameters were elevated. CONCLUSIONS: Exercise-induced splanchnic hypoperfusion results in quantifiable small intestinal injury. Importantly, the extent of intestinal injury correlates with transiently increased small intestinal permeability, indicating gut barrier dysfunction in healthy individuals. These physiological observations increase our knowledge of splanchnic hypoperfusion sequelae, and may

    Full Text Available Abstract Background Total body water (TBW estimations have been used to estimate body composition, particularly fat-free mass, to aid in nutritional interventions, and to monitor hydration status. In the past, bioimpedance spectroscopy (BIS devices have been used to estimate TBW. Previous investigations have examined the validity of the XiTRON 4000B (XiTRON Technologies BIS device for estimating TBW. Recently, a new BIS device (Imp™ SFB7 has become available, claiming greater precision when estimating TBW. The Imp™ SFB7 (SFB7 is based on similar BIS principles, while offering increased portability and a greater range of frequencies when compared to older devices, such as the XiTRON 4000B (4000B. The purpose of this study was to examine the validity of the SFB7 for estimating total body water in healthy college-age men and women compared to the 4000B and deuterium oxide (D2O. Methods Twenty-eight Caucasian men and women (14 men, 14 women; 24 ± 4 yrs; 174.6 ± 8.7 cm; 72.80 ± 17.58 kg had their TBW estimated by the SFB7, the 4000B, and D2O. Results Both BIS devices produced similar standard error of estimate (SEE and r values (SFB7, SEE = 2.12L, r = 0.98; 4000B, SEE = 2.99L, r = 0.96 when compared to D2O, though a significant constant error (CE was detected for the 4000B (2.26L, p ≤ 0.025. The 4000B produced a larger total error (TE and CE (TE = 3.81L, CE = 2.26L when compared to the SFB7 (TE = 2.21L, CE = -0.09L. Additionally, the limits of agreement were larger for the 4000B (-3.88 to 8.39L than the SFB7 (-4.50 to 4.31L. These results were consistent when sex was analyzed separately, though women produced lower SEE and TE values for both devices. Conclusion The 4000B and SFB7 are valid BIS devices when compared to D2O to estimate TBW in college-age Caucasian men and women. Furthermore, the new SFB7 device displayed greater precision in comparison to the 4000B, which may decrease the error when estimating TBW on an individual basis.

    Ralph L Widya

    Full Text Available BACKGROUND: A physiological model of increased plasma nonesterified fatty acid (NEFA levels result in myocardial triglyceride (TG accumulation, which is related to cardiac dysfunction. A pathophysiological model of increased plasma NEFA levels result in hepatic steatosis, which has been linked to abnormal myocardial energy metabolism. Hepatic steatosis is accompanied by hepatic inflammation, reflected by plasma cholesteryl ester transfer protein (CETP levels. The current study aimed to investigate effects of these models via different nutritional interventions on right ventricular (RV function. METHODS: Fifteen men (age 25.0±6.6 years were included and underwent magnetic resonance imaging and spectroscopy in this prospective crossover intervention study. RV function, myocardial and hepatic TG content, and CETP levels were assessed on three occasions: after normal diet, very low-calorie diet (VLCD, physiological model and high-fat high-energy (HFHE, pathophysiological model diet (all 3-days diets, randomly ordered, washout phase at least 14 days. RESULTS: VLCD induced a decrease in mean E deceleration by 27%. Myocardial TG content increased by 55%, whereas hepatic TG content decreased by 32%. Plasma CETP levels decreased by 14% (all P<0.05. HFHE diet induced a decrease in E/A by 19% (P<0.05. Myocardial TG content did not change, whereas hepatic TG content increased by 112% (P<0.01. Plasma CETP levels increased by 14% (P<0.05. CONCLUSIONS: These findings show that RV diastolic function is impaired after short-term VLCD and HFHE diet in healthy men, respectively a physiological and a pathophysiological model of increased plasma NEFA levels. After short-term VLCD, myocardial lipotoxicity may be of importance in decreased RV diastolic function. RV diastolic dysfunction is accompanied by increased hepatic TG content and plasma CETP levels after short-term HFHE diet, suggesting that systemic inflammation reflecting local macrophage infiltration in the

    Sleep deprivation is known to suppress circulating trophic factors such as insulin-like growth factor (IGF)-I and brain-derived neurotrophic factor (BDNF). This experiment examined the effect of an intervention involving 6 nights of extended sleep before total sleep deprivation on this catabolic profile. In a randomized crossover design, 14 young men (age range: 26-37 years) were either in an extended (EXT; time in bed: 2100-0700 h) or habitual (HAB: 2230-0700 h) sleep condition, followed by 3 days in the laboratory with blood sampling at baseline (B), after 24 h of sleep deprivation (24h-SD), and after 1 night of recovery sleep (R). In the EXT condition compared with the HAB condition, free IGF-I levels were significantly higher at B, 24h-SD, and R (P EXT did not influence growth hormone, IGF binding protein 3, BDNF, insulin, and glucose levels. The only effect of 24 h of sleep deprivation was for insulin levels, which were significantly higher after R compared with B. In a healthy adult, additional sleep over 1 week increased blood concentrations of the anabolic factor IGF-I before and during 24 h of sleep deprivation and after the subsequent recovery night without effects on BDNF. With further research, these findings may prove to be important in guiding effective lifestyle modifications to limit physical or cognitive deficits associated with IGF-I decrease with age.

    Chronic heart failure is accompanied by anorexia and increased release of B-type natriuretic peptide (BNP) from ventricular cardiomyocytes. The pathophysiological mechanisms linking heart failure and appetite regulation remain unknown. In this study, we investigated the impact of intravenous BNP administration on appetite-regulating hormones and subjective ratings of hunger and satiety in 10 healthy volunteers. Participants received in a randomized, placebo-controlled, crossover, single-blinded study (subject) placebo once and 3.0 pmol/kg/min human BNP-32 once administered as a continuous infusion during 4 h. Circulating concentrations of appetite-regulating peptides were measured hourly. Subjective ratings of hunger and satiety were evaluated by visual analog scales. BNP inhibited the fasting-induced increase in total and acylated ghrelin concentrations over time (P = 0.043 and P = 0.038, respectively). In addition, BNP decreased the subjective rating of hunger (P = 0.009) and increased the feeling of satiety (P = 0.012) when compared with placebo. There were no significant changes in circulating peptide YY, glucagon-like peptide 1, oxyntomodulin, pancreatic polypeptide, leptin, and adiponectin concentrations. In summary, our results demonstrate that BNP exerts anorectic effects and reduces ghrelin concentrations in men. These data, taken together with the known cardiovascular properties of ghrelin, support the existence of a heart-gut-brain axis, which could be therapeutically targeted in patients with heart failure and obesity.

  14. Single oral dose pharmacokinetics of decursin and decursinol angelate in healthy adult men and women.

    Full Text Available The ethanol extract of Angelica gigas Nakai (AGN root has promising anti-cancer and other bioactivities in rodent models. It is currently believed that the pyranocoumarin isomers decursin (D and decursinol angelate (DA contribute to these activities. We and others have documented that D and DA were rapidly converted to decursinol (DOH in rodents. However, our in vitro metabolism studies suggested that D and DA might be metabolized differently in humans. To test this hypothesis and address a key question for human translatability of animal model studies of D and DA or AGN extract, we conducted a single oral dose human pharmacokinetic study of D and DA delivered through an AGN-based dietary supplement Cogni.Q (purchased from Quality of Life Labs, Purchase, NY in twenty healthy subjects, i.e., 10 men and 10 women, each consuming 119 mg D and 77 mg DA from 4 vegicaps. Analyses of plasma samples using UHPLC-MS/MS showed mean time to peak concentration (Tmax of 2.1, 2.4 and 3.3 h and mean peak concentration (Cmax of 5.3, 48.1 and 2,480 nmol/L for D, DA and DOH, respectively. The terminal elimination half-life (t1/2 for D and DA was similar (17.4 and 19.3 h and each was much longer than that of DOH (7.4 h. The mean area under the curve (AUC0-48h for D, DA and DOH was estimated as 37, 335 and 27,579 h∙nmol/L, respectively. Gender-wise, men absorbed the parent compounds faster and took shorter time to reach DOH peak concentration. The human data supported an extensive conversion of D and DA to DOH, even though they metabolized DA slightly slower than rodents. Therefore, the data generated in rodent models concerning anti-cancer efficacy, safety, tissue distribution and pharmacodynamic biomarkers will likely be relevant for human translation.ClinicalTrials.gov NCT02114957.

    Despite women playing a pivotal role in shaping nutritional patterns in their families, it is the men whose ideas and preferences, after children, influence the selection and consumption of daily foods among Iranian families. This study focused on exploring the main barriers to healthy eating as experienced by male participants of the Tehran Lipid Glucose Study (TLGS). A grounded theory approach was used for analyzing participants' experiences and their perceptions regarding these barriers. Participants were 98 men, aged 25-65 years, selected and recruited from the TGLS cohort. Data collection was conducted through fourteen semi-structured focus group discussions, between 2008 and 2009. All interviews and focus group discussions were audio recorded and transcribed verbatim. Constant comparative analysis of the data was conducted manually according to the Strauss and Corbin analysis method. The most important barriers to healthy eating were: (i) Personal factors, which included two subthemes--lack of knowledge and personal taste, (ii) Communication and modeling included two subthemes--other individuals and media/advertisements; (iii) Modernization included two subthemes--nutrition transition and women's role; and (iv) Lack of access to healthy foods, which included four subthemes--Inadequate confidence, perceived risk, high cost and time limitations. Appropriate attention and prioritized policy-making to modify the socio-environmental barriers to healthy eating were explored in the current study, along with effective educational programs that could help to promote healthy eating among Iranian families.

    Objective: To determine the effects of electrical stimulation (ES) on oxygen uptake (VO2) kinetics and delta efficiency (DE) during gradual exercise. The hypothesis was that ES would attenuate the VO2-workload relation and improve DE. Methods: Fifteen healthy, untrained men (mean (SD) age 22 (5) years) were selected. Ten were electrostimulated on both quadriceps muscles with a frequency of 45–60 Hz, with 12 seconds of stimulation followed by eight seconds recovery for a total of 30 minutes a day, three days a week for six weeks. The remaining five subjects were assigned to a control group. A standardised exercise test on a cycle ergometer (ramp protocol, workload increases of 20 W/min) was performed by each subject before and after the experimental period. The slope of the VO2-power output (W) relation (ΔVO2/ΔW) and DE were calculated in each subject at moderate to high intensities (above the ventilatory threshold—that is, from 50–60% to 100% VO2max). Results: The mean (SEM) values for ΔVO2/ΔW and DE had significantly decreased and increased respectively after the six week ES programme (p<0.05; 9.8 (0.2) v 8.6 (0.5) ml O2/W/min respectively and 27.7 (0.9) v 31.5 (1.4)% respectively). Conclusions: ES could be used as a supplementary tool to improve two of the main determinants of endurance capacity, namely VO2 kinetics and work efficiency. PMID:12663356

    Full Text Available The effects of the aging process and an active life-style on the autonomic control of heart rate (HR were investigated in nine young sedentary (YS, 23 ± 2.4 years, 16 young active (YA, 22 ± 2.1 years, 8 older sedentary (OS, 63 ± 2.4 years and 8 older active (OA, 61 ± 1.1 years healthy men. Electrocardiogram was continuously recorded for 15 min at rest and for 4 min in the deep breathing test, with a breath rate of 5 to 6 cycles/min in the supine position. Resting HR and RR intervals were analyzed by time (RMSSD index and frequency domain methods. The power spectral components are reported in normalized units (nu at low (LF and high (HF frequency, and as the LF/HF ratio. The deep breathing test was analyzed by the respiratory sinus arrhythmia indices: expiration/inspiration ratio (E/I and inspiration-expiration difference (deltaIE. The active groups had lower HR and higher RMSSD index than the sedentary groups (life-style condition: sedentary vs active, P < 0.05. The older groups showed lower HFnu, higher LFnu and higher LF/HF ratio than the young groups (aging effect: young vs older, P < 0.05. The OS group had a lower E/I ratio (1.16 and deltaIE (9.7 bpm than the other groups studied (YS: 1.38, 22.4 bpm; YA: 1.40, 21.3 bpm; OA: 1.38, 18.5 bpm. The interaction between aging and life-style effects had a P < 0.05. These results suggest that aging reduces HR variability. However, regular physical activity positively affects vagal activity on the heart and consequently attenuates the effects of aging in the autonomic control of HR.

    Physiological conditions in humans affect plasma amino acid profiles that might have potential for medical use. Because the branched-chain amino acids (BCAAs) leucine, isoleucine and valine are used as medicines and supplements, we investigated the acute effects of individual BCAAs (10–90 mg/kg body weight) or mixed BCAAs ingested as a bolus on plasma amino acid profiles in young healthy men. Plasma leucine levels rapidly increased and peaked around 30 min after leucine ingestion. Concentrati...

    One possible dietary factor that may increase susceptibility to colon cancer is inadequate copper intake. The objective of this study was to investigate the effects of low and adequate copper intakes on copper nutriture and putative risk factors for colon cancer susceptibility in healthy men. Seventeen healthy free-living nonsmoking men aged 21-52 y completed a 13-wk controlled feeding study in a randomized crossover design. The basal diet contained 0.59 mg Cu/13.65 MJ. After a 1-wk equilibration period in which the men consumed the basal diet supplemented with 1.0 mg Cu/d, they were randomly assigned to receive either the basal diet or the basal diet supplemented with 2 mg Cu/d for 6 wk. After the first dietary period, the men immediately began to consume the other level of Cu for the last 6 wk. They collected their feces during the equilibration period and during the last 2 wk of the two dietary periods for free radical and fecal water analysis. Low dietary copper significantly (P copper significantly (P copper concentrations but did not affect fecal water volume, pH, iron or zinc concentrations. In contrast to the fecal analysis, hematological indicators of copper status were not significantly affected by the dietary treatments. These results suggest that low dietary copper adversely affects fecal free radical production and fecal water alkaline phosphatase activity, which are putative risk factors for colon cancer.

    Full Text Available AbstractRegular physical exercise leads increased vagal modulation of the cardiovascular system. A combination of peripheral and central processes has been proposed to underlie this adaptation. However, specific changes in the central autonomic network have not been described in human in more detail. We hypothesized that the anterior hippocampus known to be influenced by regular physical activity might be involved in the development of increased vagal modulation after a 6 weeks high intensity intervention in young healthy men (exercise group: n=17, control group: n=17. In addition to the determination of physical capacity before and after the intervention, we used resting state functional magnetic resonance imaging and synchronic heart rate variability assessment.We detected a significant increase of the power output at the anaerobic threshold of 11.4% (p<0.001, the maximum power output Pmax of 11.2% (p<0.001, and VO2max adjusted for body weight of 4.7% (p<0.001 in the exercise group (EG. Comparing baseline (T0 and post-exercise (T1 values of parasympathetic modulation of the exercise group, we observed a trend for a decrease in heart rate (p<0.06 and a significant increase of vagal modulation as indicated by RMSSD (p<0.026 during resting state. In the whole brain analysis, we found that the connectivity pattern of the right anterior hippocampus (aHC was specifically altered to the ventromedial anterior cortex, the dorsal striatum and to the dorsal vagal complex (DVC in the brainstem. Moreover, we only observed a highly significant negative correlation between increased RMSSD after exercise and decreased functional connectivity from the right aHC to DVC (r=-0.69, p=0.003. This indicates that increased vagal modulation was associated with functional connectivity between aHC and the dorsal vagal complex.In conclusion, our findings suggest that exercise associated changes in anterior hippocampal function might be involved in increased vagal

    1991-01-01

    Examined dieting to lose weight in a population of 2,107 men and 2,540 women employed in 32 worksites in the upper Midwest. Lifetime prevalence of this behavior was estimated to be 47% in men and 75% in women, and point prevalence was reported as 13% and 25% in men and women, respectively. Lifetime prevalence of participation in organized weight-loss programs was 6% in men and 31% in women; current prevalence was 1% in men and 6% in women. The strongest correlate of dieting behavior was relative body weight. In logistic regression analyses, dieting tended to be associated positively with education and occupational status and, in men only, was more prevalent among those with a history of hypertension. Dieters reported lower food intakes than nondieters, but the two groups did not differ consistently in reported physical activity. Overall, dieting appears to be a pervasive behavioral U.S. phenomenon that may contribute in part to population differences in the prevalence of obesity. PMID:1915214

    Protein-rich supplements are used widely for the management of malnutrition in young and older people. Protein is the most satiating of the macronutrients in young. It is not known how the effects of oral protein ingestion on energy intake, appetite, and gastric emptying are modified by age. The aim of the study was to determine the suppression of energy intake by protein compared with control and underlying gastric-emptying and appetite responses of oral whey protein drinks in eight healthy older men (69-80 yr) compared with eight young male controls (18-34 yr). Subjects were studied on three occasions to determine the effects of protein loads of 30 g/120 kcal and 70 g/280 kcal compared with a flavored water control-drink (0 g whey protein) on energy intake (ad libitum buffet-style meal), and gastric emptying (three-dimensional-ultrasonography) and appetite (0-180 min) in a randomized, double-blind, cross-over design. Energy intake was suppressed by the protein compared with control (P = 0.034). Suppression of energy intake by protein was less in older men (1 ± 5%) than in young controls (15 ± 2%; P = 0.008). Cumulative energy intake (meal+drink) on the protein drink days compared with the control day increased more in older (18 ± 6%) men than young (1 ± 3%) controls (P = 0.008). Gastric emptying of all three drinks was slower in older men (50% gastric-emptying time: 68 ± 5 min) than young controls (36 ± 5 min; P = 0.007). Appetite decreased in young, while it increased in older (P protein-induced suppression of energy intake by whey protein compared with young controls, so that in the elderly men, protein ingestion increased overall energy intake more than in the young men.

    Full Text Available BACKGROUND: The application of the Shuttle Walking Test (SWT to assess cardiorespiratory fitness and the intensity of this test in healthy participants has rarely been studied. This study aimed to assess and correlate the cardiorespiratory responses of the SWT with the cardiopulmonary exercise testing (CEPT and to develop a regression equation for the prediction of peak oxygen uptake (VO2 peak in healthy sedentary adult men. METHODS: In the first stage of this study, 12 participants underwent the SWT and the CEPT on a treadmill. In the second stage, 53 participants underwent the SWT twice. In both phases, the VO2 peak, respiratory exchange ratio (R, and heart rate (HR were evaluated. RESULTS: Similar results in VO2 peak (P>0.05, R peak (P>0.05 and predicted maximum HR (P>0.05 were obtained between the SWT and CEPT. Both tests showed strong and significant correlations of VO2 peak (r = 0.704, P = 0.01 and R peak (r = 0.737, P0.05 was found. CONCLUSIONS: The SWT produced maximal cardiorespiratory responses comparable to the CEPT, and the developed equation showed viability for the prediction of VO2 peak in healthy sedentary men.

    Little attention has been paid to the physical activity (PA) and nutrition behaviors of middle-aged men; thus, the aim of this study was to gather information and gain insight into the PA and nutrition behaviors of these men. Six focus group sessions were undertaken with middle-aged men (N = 30) from regional Australia to explore the challenges and motivations to PA participation and healthy eating. Men had a good understanding of PA and nutrition; however, this was sometimes confounded by inconsistent media messages. Work commitments and family responsibilities were barriers to PA, while poor cooking skills and abilities were barriers to healthy eating. Disease prevention, weight management, and being a good role model were motivators for PA and healthy eating. By understanding what a man wants, PA and nutrition interventions can be designed and delivered to meet the needs of this hard-to-reach population.

    This study aimed to assess the effect of virgin argan oil (VAO) and extra virgin olive oil (EVO) on the hormonal profile of androgens and anthropometric parameters among healthy adult Moroccan men during a controlled nutritional intervention. The study was carried out on 60 young and healthy male volunteers aged between 23 and 40 years old. During a stabilization period of 2 weeks they consumed butter. The group was then randomized into two categories, the first one consuming VAO and the second EVO for 3 weeks. Testosterone (T), luteinizing hormone (LH) and dehydroepiandrosterone (DHEAS) serum concentrations were measured at the beginning of the study and at the end of each period. The Mann-Whitney test was used to compare the two groups (VAO and EVO) during each step of the study. Differences in androgens and anthropometric parameters between the baseline and after 3 weeks of the diet in the VAO and EVO groups were analyzed using the Wilcoxon test. T and LH serum concentrations significantly increased after the intervention period. T levels increased by 19.9% and 17.4% (p argan or olive oils. The results suggest that consumption of AVO and EVO might be the origin of a positive action on the androgen hormonal profile of men.

    The present experiments were performed to elucidate the acute effects of intravenous infusion of glucagon-like peptide (GLP)-1 on central and renal hemodynamics in healthy men. Seven healthy middle-aged men were examined on two different occasions in random order. During a 3-h infusion of either GLP-1 (1.5 pmol·kg⁻¹·min⁻¹) or saline, cardiac output was estimated noninvasively, and intraarterial blood pressure and heart rate were measured continuously. Renal plasma flow, glomerular filtration rate, and uptake/release of hormones and ions were measured by Fick's Principle after catheterization of a renal vein. Subjects remained supine during the experiments. During GLP-1 infusion, both systolic blood pressure and arterial pulse pressure increased by 5±1 mmHg (P=0.015 and P=0.002, respectively). Heart rate increased by 5±1 beats/min (P=0.005), and cardiac output increased by 18% (P=0.016). Renal plasma flow and glomerular filtration rate as well as the clearance of Na⁺ and Li⁺ were not affected by GLP-1. However, plasma renin activity decreased (P=0.037), whereas plasma levels of atrial natriuretic peptide were unaffected. Renal extraction of intact GLP-1 was 43% (Pvolume and heart rate, whereas no effect on renal hemodynamics could be demonstrated despite significant extraction of both the intact hormone and its primary metabolite.

    In the present study we aimed to evaluate whether oxidative stress and inflammation induced by strenuous exercise affect glycocalyx integrity and endothelial function. Twenty one young, untrained healthy men performed a maximal incremental cycling exercise - until exhaustion. Markers of glycocalyx shedding (syndecan-1, heparan sulfate and hyaluronic acid), endothelial status (nitric oxide and prostacyclin metabolites - nitrate, nitrite, 6-keto-prostaglandin F(1alpha)), oxidative stress (8-oxo-2'-deoxyguanosine) and antioxidant capacity (uric acid, non-enzymatic antioxidant capacity) as well as markers of inflammation (sVCAM-1 and sICAM-1) were analyzed in venous blood samples taken at rest and at the end of exercise. The applied strenuous exercise caused a 5-fold increase in plasma lactate and hypoxanthine concentrations (p<0.001), a fall in plasma uric acid concentration and non-enzymatic antioxidant capacity (p<10(-4)), accompanied by an increase (p=0.003) in sVCAM-1 concentration. Plasma 6-keto-prostaglandin F(1alpha) concentration increased (p=0.006) at exhaustion, while nitrate and nitrite concentrations were not affected. Surprisingly, no significant changes in serum syndecan-1 and heparan sulfate concentrations were observed. We have concluded, that a single bout of severe-intensity exercise is well accommodated by endothelium in young, healthy men as it neither results in evident glycocalyx disruption nor in the impairment of nitric oxide and prostacyclin production.

    Full Text Available Carboxymethyl-glucan (CM-G is a water-soluble derivative of β(1→3(1→6 glucan, a well-known immunostimulant and antioxidant compound. In this experimental, randomized and placebo-controlled study, the effects of oral CM-G intake over a 60-day period on the peripheral blood, cholesterol, glycemic index and malondialdehyde (MDA levels of healthy men was assessed. The CM-G was obtained from spent brewer’s yeast (S. uvarum with DS 0.8 and molecular weight of 2.2 × 105 Da. Following CM-G administration, no changes were observed in red and white blood cell, hematocrit, hemoglobin and platelet counts, or in cholesterol and glycemic indices. After 30 days of CM-G administration, the MDA levels decreased significantly (p ≤ 0.05 in men receiving CM-G. The results showed for the first time that CM-G may act as an adjuvant in preventing oxidative damage in healthy humans.

    Nitric oxide (NO) has been demonstrated to enhance the maximal shortening velocity and maximal power of rodent muscle. Dietary nitrate (NO3(-)) intake has been demonstrated to increase NO bioavailability in humans. We therefore hypothesized that acute dietary NO3(-) intake (in the form of a concentrated beetroot juice (BRJ) supplement) would improve muscle speed and power in humans. To test this hypothesis, healthy men and women (n = 12; age = 22-50 y) were studied using a randomized, double-blind, placebo-controlled crossover design. After an overnight fast, subjects ingested 140 mL of BRJ either containing or devoid of 11.2 mmol of NO3(-). After 2 h, knee extensor contractile function was assessed using a Biodex 4 isokinetic dynamometer. Breath NO levels were also measured periodically using a Niox Mino analyzer as a biomarker of whole-body NO production. No significant changes in breath NO were observed in the placebo trial, whereas breath NO rose by 61% (P power at the highest angular velocity tested (i.e., 6.28 rad/s). Calculated maximal knee extensor power was therefore greater (i.e., 7.90 ± 0.59 vs. 7.44 ± 0.53 W/kg; P power in healthy men and women.

This study aimed to investigate the acute effects of KT on the maximum concentric and eccentric quadriceps isokinetic strength. Study Design. This is a single-blinded, placebo crossover, repeated measures study. Methods. Maximum isokinetic concentric/eccentric extension torque, work, and power were assessed by an isokinetic dynamometer without taping (NT and with KT or placebo taping (PT in 17 healthy young men. Repeated measures one-way analysis of variance (ANOVA was used for statistical analyses. Results. Testing concentric contractions at 60°/s or 180°/s isokinetic speed, no significant differences in peak torque (Nm, total work (J, or mean power (W were noted among the application modes under different conditions. Testing eccentric contractions at 30°/s or 60°/s isokinetic speed, no significant differences in mentioned parameters were noted, respectively. KT on the quadriceps neither decreased nor increased muscle strength in the participants. Conclusion. KT application onto the skin overlying the quadriceps muscle does not enhance the strength or power of knee extensors in healthy men.

Health status was assessed by clinical examination and serological evaluation. Individuals with severe anemia or hemoconcentration, prior traumas or major surgical intervention, smokers, and pregnant or lactating women were excluded from the study. The MAP/Hct association was positive and significant (P=0.04 for women and negative, albeit not significantly so, for men. The MAP/Hct association was also evaluated in subgroups of the same population with a progressive step-by-step exclusion of: individuals with cholesterol >200 mg/dL; triglycerides >200 mg/dL; body mass index >25 kg/m2; and glucose >100 mg/dL. This consecutively reduced the strength of the positive MAP/Hct association in women, which became negative – although not significantly so – when all anomalously high factors were excluded. The same trend was found in men. Our study indicates that previously reported positive trends in the relationship between the MAP and Hct in the population are not present in a young, healthy population of men

    Cordyceps militaris is a mushroom traditionally used for diverse pharmaceutical purposes in East Asia, including China, and has been found to be effective for enhancing immunity through various types of animal testing. The aim of this study is to determine the efficacy of C. militaris for enhancing cell-mediated immunity and its safety in healthy male adults. Healthy male adults were divided into the experimental group (n = 39), given 1.5 g/day of ethanol treated C. militaris in capsules, and the control group (n = 40), given the same number of identical placebo capsules filled with microcrystalline cellulose and lactose for 4 weeks from February 13 to March 14, 2012; the natural killer (NK) cell activity, lymphocyte proliferation index (PI), and T-helper cell 1 (Th1) cytokine cluster (interferon [IFN]-γ, interleukin [IL]-12, IL-2, and tumor necrosis factor [TNF]-α) were measured, along with stability test, at weeks 0, 2, and 4. The C. militaris group showed a statistically significant greater increase in NK200 (P = .0010), lymphocyte PI (P ≤ .0001), IL-2 (P = .0096), and IFN-γ (P = .0126), compared with the basal level, than the placebo group. There was no statistically significant adverse reaction. C. militaris enhanced the NK cell activity and lymphocyte proliferation and partially increased Th1 cytokine secretion. Therefore, C. militaris is safe and effective for enhancing cell-mediated immunity of healthy male adults. PMID:26284906

    Men have not been the focus of health monitoring and reporting in German-speaking Switzerland so far and are a largely neglected target group of governmental preventive efforts. Without good reason. Men have a substantial preventive potential regarding health, health behavior and use of health and medical services, as can be seen in the recently published global health report of the Canton Zurich. Men have a shorter life expectancy compared to women and a significantly higher mortality with regard to strongly behavior-related chronic diseases as well as fatal traffic accidents and suicides. Men also show comparably unfavourable health behavior and a reduced utilization of health services. The stronger, but also less healthy and less healthy behaving sex should increasingly be the focus of health reporting and health monitoring in the future. PMID:26422073

    Prolonged physical inactivity or bed rest (BR) due to illness or other factors can result in significant declines in physical health and even cognitive functions. Based on random selection, 7 healthy older adult men received computerized spatial navigation training, while 8 served as active controls during 14-day BR. Greater post-BR declines were seen in normal and complex (dual-task) walking for the control as compared to intervention group, suggesting that computerized spatial navigation training can successfully moderate detrimental BR effects. Findings underline the generalization of cognitive-based intervention to the motor domain and potentially support their use to supplement BR interventions (e.g., exercise and nutrition).

  4. Breakfast meal composition influences plasma tryptophan to large neutral amino acid ratios of healthy lean young men

    International Nuclear Information System (INIS)

    The effect of a carbohydrate, a 20% protein, or a carbohydrate +0.3% tryptophan TRP breakfast on plasma large neutral amino acid ratio was studied in 6 healthy men. The carbohydrate-rich meal produced shifts in plasma amino acid concentrations such that plasma TRP/LNAA ratios increased from 0.13 to 0.15 (p<0.04) and the protein meal decreased the ratio from 0.14 to 0.11 (p<0.04) after 1 hour. Addition of 0.3% TRP to the carbohydrate-rich meal increased plasma TRP/LNAA ratios more than 2-fold. The TRP containing meal was thus the only one likely to influence brain 5-HT synthesis, although the difference between the plasma TRP/LNAA ratios after carbohydrate and protein breakfasts suggests that the brain may distinguish, by synthesizing more or less 5-HT, the composition of breakfast meals.

    The purpose of this study was to investigate the effect of Opuntia ficus-indica (OFI) cladode and fruit-skin extract on blood glucose and plasma insulin increments due to high-dose carbohydrate ingestion, before and after exercise. Healthy, physically active men (n = 6; 21.0 ± 1.6 years, 78.1 ± 6.0 kg) participated in a double-blind placebo-controlled crossover study involving 2 experimental sessions. In each session, the subjects successively underwent an oral glucose tolerance test at rest (OGTT(R)), a 30-min cycling bout at ~75% VO(2max), and another OGTT after exercise (OGTT(EX)). They received capsules containing either 1,000 mg OFI or placebo (PL) 30 min before and immediately after the OGTT(R). Blood samples were collected before (t₀) and at 30-min intervals after ingestion of 75 g glucose for determination of blood glucose and serum insulin. In OGTT(EX) an additional 75-g oral glucose bolus was administered at t₆₀. In OGTT(R), OFI administration reduced the area under the glucose curve (AUC(GLUC)) by 26%, mainly due to lower blood glucose levels at t₃₀ and t₆₀ (p < .05). Furthermore, a higher serum insulin concentration was noted after OFI intake at baseline and at t₃₀ (p < .05). In OGTT(EX), blood glucose at t₆₀ was ~10% lower in OFI than in PL, which resulted in a decreased AUC(GLUC) (-37%, p < .05). However, insulin values and AUC(INS) were not different between OFI and PL. In conclusion, the current study shows that OFI extract can increase plasma insulin and thereby facilitate the clearance of an oral glucose load from the circulation at rest and after endurance exercise in healthy men.

    The aim of thisstudy was to conduct a randomized, double-blind and placebo-controlled study to investigate the effects of D-004, a lipid extract of the Roystonea regia fruit that prevents testosterone- and phenylepinephrine-induced prostate hyperplasia in rodents, on plasma oxidative markers in healthy men. We enrolled male volunteers (20-55 years) in good health and without lower urinary tract symptoms. Thirty-four eligible participants were randomized to placebo or D-004 (320 mg) capsules administered daily for 6 weeks. An interim check-up and a final visit were conducted after 3 and 6 weeks of therapy, respectively. Physical examinations were performed at each visit, and laboratory tests were performed at baseline and at treatment completion. Oxidative variables included plasma malondiaidehyde (MDA), total hydroxyperoxides (TOH), sulphydryl (SH) groups and total antioxidant status (TAS). We assessed treatment compliance and addressed adverse experiences (AEs) at weeks 3 and 6. At week 6, with D-004, the mean reductions of plasma MDA (26.7%), TOH (18.8%) and SH groups (31.6%), and the mean increase of TAS (35.3%) were significantly different from those of placebo (P<0.001 for plasma TAS, P<0.0001 for all other comparisons). D-004 did not differ from the placebo in safety indicators. There were two withdrawals (both in the D-004 group), with one due to dyspepsia (the only AE during the trial). In conclusion, D-004 displayed antioxidant effects on plasma oxidative markers in healthy men, which was consistent with findings from laboratory experimental studies.

    Multiple-type human papillomaviruses (HPV) infection presents a greater risk for persistence in asymptomatic individuals and may accelerate cancer development. To extend the scope of HPV types defined by probe-based assays, multiplexing deep sequencing of HPV L1, coupled with an HPV-QUEST genotyping server and a bioinformatic pipeline, was established and applied to survey the diversity of HPV genotypes among a subset of healthy men from the HPV in Men (HIM) Multinational Study. Twenty-one HPV genotypes (12 high-risk and 9 low-risk) were detected in the genital area from 18 asymptomatic individuals. A single HPV type, either HPV16, HPV6b or HPV83, was detected in 7 individuals, while coinfection by 2 to 5 high-risk and/or low-risk genotypes was identified in the other 11 participants. In two individuals studied for over one year, HPV16 persisted, while fluctuations of coinfecting genotypes occurred. HPV L1 regions were generally identical between query and reference sequences, although nonsynonymous and synonymous nucleotide polymorphisms of HPV16, 18, 31, 35h, 59, 70, 73, cand85, 6b, 62, 81, 83, cand89 or JEB2 L1 genotypes, mostly unidentified by linear array, were evident. Deep sequencing coupled with HPV-QUEST provides efficient and unambiguous classification of HPV genotypes in multiple-type HPV infection in host ecosystems.

    There are few studies on the relationship between skeletal muscle mass and balance in the young ages. We investigated the relationship between appendicular skeletal muscle mass, isokinetic muscle strength of lower extremity, and balance among healthy young men using relative skeletal muscle index. Thirty men were grouped according to relative appendicular skeletal muscle mass index: higher skeletal muscle group (n = 15) and lower skeletal muscle group (n = 15). Static and dynamic balance abilities were measured using the following: a test where participants stood on one leg with eyes closed, a modified Clinical Test of Sensory Interaction on Balance (mCTSIB) with eyes open and eyes closed, a stability test, and limits of stability test. The muscle strength of lower extremities was measured with an isokinetic analyser in hip, knee, and ankle joints. Participants with higher appendicular skeletal muscle mass were significantly more stable in maintaining dynamic balance than those with lower appendicular skeletal muscle mass. Moreover, appendicular skeletal muscle mass index was positively correlated with dynamic balance ability. Participants with higher appendicular skeletal muscle mass had stronger strength in the lower extremity, and there were significant differences in the isokinetic torque ratios between groups. From these results, it can be inferred that higher appendicular skeletal muscle mass relates to muscle strength and the alteration in the peak torque ratio of the lower extremity, contributing to the maintenance of balance.

    Full Text Available OBJECTIVE: To determine the reliability of the measurement of net joint power during repeated gait measurements within one day and between two different measurement days. METHODS: Thirty able-bodied men who underwent repeated gait measurements within a day and between days participated in this research. An acceptable trial was one in which the participant complied with the range of walking speed 1.45 m/s ± 5%. Three-dimensional angles, angular velocities, net moments of force and net power for the ankle, knee and hip joints were determined using external passive reflective markers, an 8-camera motion analysis system and two force plates. RESULTS: This study presents the patterns of the net power in the fundamental joints of the lower limbs in young healthy men at standard gait velocity. Intraclass correlation coefficients for net joint power measure reached values in the range of .70 to .89 on the first day, from .69 to .86 on the second day, and from .67 to .83 in total. CONCLUSION: The reliability of the measurement of the peak net joint power within one day and between the two measurement days was evaluated as satisfactory. The study provides the value of minimal detectable change for the peak net power of the lower limb in the sagittal plane during gait. The net joint power appears to be a reliable measure and could be used in practice.

    Functional gastrointestinal disorders (FGIDs), including functional dyspepsia (FD), are common chronic disorders even in the younger population. Physical activity is advocated for patients with FGIDs, although the evidence is insufficient. We investigated the association between the intensity of regular exercise and gastric emptying to determine the effect of physical activity on dyspeptic symptoms. Thirty healthy individuals were selected and divided into three groups (low, moderate, and high) using the index of total exercise intensity in a week. Gastric emptying was evaluated by the 13C-acetate breath test. Gastroesophageal reflux symptoms, dyspeptic symptoms, stool forms, scores of anxiety and depression, and scores of sleep quality were also compared. Baseline scores of gastroesophageal reflux symptoms, anxiety, depression, and sleep quality were not different among the three groups. Gastric emptying was significantly faster in low-intensity exercise group than the moderate-intensity exercise group. Although the presence of loose stool and alcohol consumption were also associated with the intensity of regular exercise, these variables were not confounders. In conclusion, the intensity of regular exercise was independently associated with gastric emptying in healthy individuals. These baseline data would be useful for consideration of an optimal exercise intervention for the treatment of FD.

    Environmental factors have long been known to influence immune responses. In particular, clinical studies about the association between migration and increased risk of atopy/asthma have provided important information on the role of migration associated large sets of environmental exposures in the development of allergic diseases. However, investigations about environmental effects on immune responses are mostly limited in candidate environmental exposures, such as air pollution. The influences of large sets of environmental exposures on immune responses are still largely unknown. A simulated 520-d Mars mission provided an opportunity to investigate this topic. Six healthy males lived in a closed habitat simulating a spacecraft for 520 days. When they exited their "spacecraft" after the mission, the scenario was similar to that of migration, involving exposure to a new set of environmental pollutants and allergens. We measured multiple immune parameters with blood samples at chosen time points after the mission. At the early adaptation stage, highly enhanced cytokine responses were observed upon ex vivo antigen stimulations. For cell population frequencies, we found the subjects displayed increased neutrophils. These results may presumably represent the immune changes occurred in healthy humans when migrating, indicating that large sets of environmental exposures may trigger aberrant immune activity.

    Human serum contains many different antioxidants which may be important in the maintenance of an antioxidant status. The aim of this study was to evaluate the relationship between lipid peroxidation and total plasma antioxidant capacity in healthy smoking and non-smoking young and elderly subjects. Plasma concetrations of alpha-tocopherol, beta-carotene and ascorbic acid were detected by HPLC. Additionally, in the in vitro experiments, the effects of exogenous compounds (ascorbic acid, uric acid, Trolox) on total ferric reducing activity of plasma were tested. We demonstrated that total antioxidant capacity of plasma obtained from healthy non-smoking young subjects was significantly higher than plasma antioxidant capacity of smoking elderly subjects. The concentration of thiobarbituric acid-reactive substances (TBARS) (p < 0.001) in young non-smoking volunteers was lower than that in young smokers. The concentration of TBARS in elderly non-smoking volunteers was lower than in elderly smokers. Plasma concentrations of alpha-tocopherol, beta-carotene and ascorbic acid were significantly lower in elderly smokers than in elderly non-smokers of same age. No difference in plasma levels of alpha-tocopherol, beta-carotene and ascorbic acid were found in 22-year-old smoking and non-smoking subjects. In vitro addition of ascorbic acid, uric acid, or Trolox to plasma samples significantly increased their total antioxidant capacity. Decrease of FRAP values and increase of TBARS concentra-' tions is a significant physiologic condition of aging process. Supplementation of antioxidants could be useful for the enhancement of plasma antioxidant status (Tab. 1, Fig. 3, Ref: 35).

    Full Text Available Abstract Background Uncontrollable aversive events are associated with feelings of helplessness and cortisol elevation and are suitable as a model of depression. The high comorbidity of depression and pain symptoms and the importance of controllability in both conditions are clinically well-known but empirical studies are scarce. The study investigated the relationship of pain experience, helplessness, and cortisol secretion after controllable vs. uncontrollable electric skin stimulation in healthy male individuals. Methods Sixty-four male volunteers were randomly assigned to receive 30 controllable (self-administered or uncontrollable (experimenter-administered painful electric skin stimuli. Perceived pain intensity (PPI, subjective helplessness ratings, and salivary cortisol concentrations were assessed. PPI was assessed after stress exposure. For salivary cortisol concentrations and subjective helplessness ratings, areas under the response curve (AUC were calculated. Results After uncontrollable vs. controllable stress exposure significantly higher PPI ratings (P = 0.023, higher subjective helplessness AUC (P Conclusions The results confirm the impact of uncontrollability on stress responses in humans; the relationship of PPI with subjective helplessness and salivary cortisol suggests a cognitive-affective sensitization of pain perception, particularly under uncontrollable conditions.

    Objective To investigate the effect of dietary saturated fat (SFA) from animal sources on the urine excretion 11-dehydro thromboxane B2 (TXB2) and 6-keto prostaglandin F 1α (PGF 1α) in 27 healthy free-living male subjects aged 30 to 55 years. Methods It was a randomized crossover design. Each volunteer was randomly assigned to one of the two diets (high fat and low fat) for a period of 4 weeks, after which each subject resumed his usual diet for 2 weeks as a ‘wash-out period',before being assigned to the other diet for an additional 4 weeks. Results Serum proportion of 20:4n-6 was 5% lower in the high fat (6.2% of total fatty acid) than in the low fat diet (6.5% of total fatty acid), which was associated with a significantly decreased ratio of the urinary excretion 11-dehydro TXB2 to 6-keto PGF 1α (P<0.05). However, there was no significant fall in the absolute urinary excretion of 11-dehydro TXB2. Conclusions Diet rich in SFA from animal sources may influence TXA2 formation via effect on tissue proportion of 20:4n-6.

    AIM: To determine serum γ-glutamyltransferase (GGT), alanine aminotransferase (ALT), and aspartate aminotransferase (AST) activity, and to assess their correlation with demographic and clinical findings in healthy blood donors.METHODS: This cross-sectional study was performed in 934 male blood donors, aged 18 to 68 years, who consecutively attended Tehran blood transfusion service in 2006. All participants were seronegative for HBV or HCV infections, non alcohol users, and all underwent a standard interview and anthropometric tests. Clinical and biochemical parameters including AST, ALT, and GGT activities were determined. Patients taking drugs known to cause hepatic fat deposition were excluded. For AST, ALT, and GGT variables, we used 33.33 and 66.66 percentiles, so that each of them was divided into three tertiles.RESULTS: Mean AST, ALT, and GGT activities were 25.26 ± 12.58 U/L (normal range 5-35 U/L), 33.13 ± 22.98 (normal range 5-35 U/L), and 25.11 ± 18.32 (normal range 6-37 U/L), respectively. By univariate analyses, there were significant associations between increasing AST, ALT, or GGT tertiles and age, body weight, body mass index, and waist and hip circumferences (P < 0.05). By multiple linear regression analyses, ALT was found to be positively correlated with dyslipidemia (B = 6.988, P = 0.038), whereas ALT and AST were negatively correlated with age. AST, ALT, and GGT levels had positive correlation with family history of liver disease (B = 15.763, P < 0.001), (B = 32.345, P < 0.001), (B =24.415, P < 0.001), respectively.CONCLUSION: Although we did not determine the cutoffs of the upper normal limits for AST, ALT, and GGT levels, we would suggest screening asymptomatic patients with dyslipidemia and also subjects with a family history of liver disease.

    Full Text Available In this study we assessed the effect of acute hypoxia on post-exercise parasympathetic reactivation inferred from heart rate (HR recovery (HRR and HR variability (HRV indices. Ten healthy males participated in this study. Following 10 min of seated rest, participants performed 5 min of submaximal running at the speed associated with the first ventilatory threshold (Sub followed by a 20-s all-out supramaximal sprint (Supra. Both the Sub and Supra runs were immediately followed by 15 min of seated passive recovery. The resting and exercise sequence were performed in both normoxia (N and normobaric hypoxia (H (FiO2 = 15.4%. HRR indices (e.g., heart beats recovered in the first minute after exercise cessation, HRR60s and vagal-related HRV indices (i.e., natural logarithm of the square root of the mean of the sum of the squared differences between adjacent normal R-R intervals (Ln rMSSD were calculated for both conditions. Difference in the changes between N and H for all HR-derived indices were also calculated for both Sub and Supra. HRR60s was greater in N compared with H following Sub only (60±14 vs. 52±19 beats.min-1, P = 0.016. Ln rMSSD was greater in N compared with H (post Sub: 3.60±0.45 vs. 3.28±0.44 ms in N and H, respectively and post Supra: 2.66±0.54 vs. 2.65±0.63 ms, main condition effect P = 0.02. When comparing the difference in the changes, hypoxia decreased HRR60s (-14.3%±17.2 vs. 5.2-0.5%±19.3; following Sub and Supra, respectively; P = 0.03 and Ln rMSSD (-8.6%±7.0 vs. 2.0%±13.3, following Sub and Supra, respectively; P = 0.08, Cohen’s effect size = 0.62 more following Sub than Supra. While hypoxia may delay parasympathetic reactivation following submaximal exercise, its effect is not apparent following supramaximal exercise. This may suggest that the effect of blood O2 partial pressure on parasympathetic reactivation is limited under heightened sympathetic activation.

    Evaluation of severe functional gastrointestinal motility disorders requires an investigation of the entire gastrointestinal tract. This should be possible with a single radionuclide imaging study. The purpose of this study was (1) to define normal values of small-bowel transit in men and women and (2) to assess a possible difference between gender or test meal, since it has been shown that women have slower gastric emptying than men, and gastric emptying of solids is slower than liquids. A standard gastric-emptying test for a solid (technetium-99m sulphur colloids, 230 Kcal) and liquid (indium-111 DTPA water) test meal was performed in 12 healthy male and 12 healthy female volunteers. After 135 min, the volunteer was place in the supine position for static imaging of the abdomen every 15 min for 6 h. Decay and crossover-corrected geometric mean gastric-emptying data were fit to a modified power exponential function to determine the 10% stomach emptying time for solids and liquids separately. An ROI was drawn around the caecum and ascending colon to determine the arrival time of at least 10% of the solid and liquid test meal. Ten percent small-bowel transit time (10% SBTT) and orocaecal transit time (OCTT) were calculated. The OCTT for males and females, respectively for solids and liquids, are 294.6{+-}18.8; 301.3{+-}24.5; 294.6{+-}18.8 and 301.3{+-}24.5 min. The 10% SBTT for males and females, respectively for solids and liquids, are 280.3{+-}18.4; 280.6{+-}24.0; 288.2{+-}18.9 and 297.4{+-}24.4 (means{+-}SEM) min. We observed a simultaneous transfer of solids and liquids from the terminal ileum to caecum (correlation coefficient 0.90). There is no statistically significant difference in SBTT between gender or solids and liquids. In contrast to the gastric-emptying time, the SBTT of solids and liquids were not significantly different nor was a gender difference found. Determination of the OCTT seems to be the simplest and most accurate approach to measure SBTT

    FSK0808, a biosimilar of filgrastim, is a recombinant human granulocyte colony-stimulating factor developed by Fuji Pharmaceuticals and Mochida Pharmaceutical Co., Ltd. We conducted a double-blind, randomized, crossover study in healthy Japanese men, comparing the number of CD34-positive cells (CD34(+) cells) after repeated subcutaneous administration of either FSK0808 or the reference filgrastim (Gran(®) ). As primary endpoints, we compared the maximum number of CD34(+) cells (CD34(+)  Cmax ) and the time to reach CD34(+) Cmax (CD34(+) tmax ). As secondary endpoints, we compared the area under the curve for the number of CD34(+) cells over time at the 410 hours time point (CD34(+) AUC0-410 ), the parameters used to calculate the pharmacodynamic index of the absolute neutrophil count, and the pharmacokinetic parameters. Regarding the CD34(+) Cmax and the CD34(+) AUC0-410 values, the 95% confidence interval (CI) of the differences between the mean values for each drug was within the range of log(0.8)-log(1.25). With respect to the differences in the median values between drugs, the ratio against the reference filgrastim median value in the 95% CI was within the range of ± 0.2 for the CD34(+) tmax value. From these results, we considered that these drugs display equivalent pharmacodynamic and pharmacokinetic properties. PMID:27128214

    The objective of this study was to describe the interaction of beverage and food intake with meal advancement in healthy adults. In a randomized controlled study, 29 men and women consumed to satiation, over 20 min, a pizza meal with one of the five beverages including water, 1% milk, orange juice, regular cola and diet cola. Mealtime food and fluid intake were measured, within each of three 7-min phases of the meal. A progressive decline occurred from phase 1 to 3 in fluid intake and food intake, averaging 59 mL and 268 kcal (P < 0.0001) respectively; however, the relative intake of fluid to food (mL/kcal) increased (P < 0.0001). Beverage type was not a factor. All beverages resulted in similar fluid volume intake compared to water. However, caloric beverages led to higher mealtime total energy intake compared to water (P < 0.001) and diet cola (P < 0.0001). Baseline thirst correlated positively with both fluid (r = 0.28; P < 0.001) and food (r = 0.16; P < 0.05) intakes at the meal, whereas baseline appetite associated positively only with mealtime food intake (r = 0.23; P<0.01). In conclusion, mealtime fluid and food intakes interact, unaffected by beverage characteristics, to increase the ratio of fluid to food intake with meal progression. PMID:25700893

    The impact of sleep restriction on the endogenous circadian rhythms of hunger and satiety were examined in 28 healthy young men. Participants were scheduled to 2 × 24-h days of baseline followed by 8 × 28-h days of forced desynchrony during which sleep was either moderately restricted (equivalent to 6 h in bed/24 h; n = 14) or severely restricted (equivalent to 4 h in bed/24 h; n = 14). Self-reported hunger and satisfaction were assessed every 2.5 h during wake periods using visual analogue scales. Participants were served standardised meals and snacks at regular intervals and were not permitted to eat ad libitum. Core body temperature was continuously recorded with rectal thermistors to determine circadian phase. Both hunger and satiety exhibited a marked endogenous circadian rhythm. Hunger was highest, and satiety was lowest, in the biological evening (i.e., ~17:00-21:00 h) whereas hunger was lowest, and satiety was highest in the biological night (i.e., 01:00-05:00 h). The results are consistent with expectations based on previous reports and may explain in some part the decrease in appetite that is commonly reported by individuals who are required to work at night. Interestingly, the endogenous rhythms of hunger and satiety do not appear to be altered by severe--as compared to moderate--sleep restriction.

    The baroreflex that acts to blunt blood pressure (BP) variations through opposite variations in heart rate should limit the BP increase produced by an emotional challenge. However, relations between baroreflex sensitivity and BP reactivity induced by a psychological stress in a large group of adults have never been firmly established. In 280 healthy men, rest (10 minutes) and stress (5 minutes) BP and heart rate were recorded beat to beat by a blood pressure monitor. The mental stress was elicited by a well-standardized computerized version of a word color conflict stress test (Stroop Color Test). Rest and stress baroreflex sensitivity was assessed by the cross-spectral analysis of BP and heart rate and by the sequence method. The stress-induced increase in systolic BP (22.4+/-0.1 mm Hg) was not correlated with resting baroreflex sensitivity but was slightly correlated (r=0.2, P<0.001) with BP variability assessed either by standard deviation or by mid-frequency band spectral power. Our results suggested that a centrally mediated sympathetic stimulation overcame cardiac autonomic regulation and emphasized the role of the sympathetic vasoconstriction in the pressure response at the onset of the stressing stimulation. During the sustained sympathoexcitatory phase, the cardiac baroreflex blunts BP variations but at a lower sensitivity.

    Mannan-binding lectin (MBL) is a serum acute-phase protein and a complement component secreted by the liver. Its deficiency caused by point mutations in the MBL gene has recently been associated with severe atherosclerosis. In this study, we investigated the effect of MBL variant alleles on coronary artery reactivity, which is an early marker of coronary dysfunction and predicts the development of atherosclerosis and coronary artery disease. The study population consisted of 51 apparently healthy, normo- or mildly hypercholesterolemic young men. Myocardial blood flow was measured at baseline and during adenosine-induced hyperemia with positron emission tomography (PET), and MBL genotyping was performed using restriction fragment-length polymorphism. As a result, MBL variant alleles had no effect on coronary artery reactivity. This finding suggests that MBL deficiency is not an independent risk factor for coronary dysfunction and early atherogenic changes but rather a co-factor in the development of atherosclerosis. Thus, the connection of MBL variant alleles with environmental risk factors in atherosclerosis should further be assessed. PMID:15458704

  9. Inspiratory and expiratory pulmonary CT: change of bronchial and accompanying pulmonary arterial diameter during respiration in healthy adult men

    International Nuclear Information System (INIS)

    To evaluate changes in the diameter of bronchi and pulmonary arteries during respiration. The ratio of the diameter of matched inner bronchi and accompanying pulmonary arteries was calculated from full inspiration and expiration HRCT of healthy men. In 106 pairs of matched bronchi and pulmonary arteries, the bronhchial-arterial ratios were0.61 ±0.18(upper lung), 0.72±0.21(lower lung), and 0.65±0.20(total) at full inspiration and 0.51±0.32(upper lung), 0.52±0.15(lower lung), and 0.51±0.26(total) at full expiration HRCT, denotiong a statistically significant increase in bronchial diameter of the entire lung at full inspiration. The inner diameter of the bronchus was larger than the diameter of the accompanying pulmonary artery by 0.1% at full expiration and 8.5% at full inspiration. The result of this study would be helpful in understanding the physiology of the lung during respiration

    Ellinger, S.; Arendt, B. M.; Boese, A.; Juschus, M.; Schaefer, S.; Stoffel-Wagner, B.; Goerlich, R.

    Background: Astronauts are exposed to oxidative stress due to radiation and microgravity, which might impair immune functions. Effects of hypocaloric nutrition as often observed in astronauts on oxidative stress and immune functions are not clear. We investigated, if microgravity, simulated by 6 Head-down tilt (HDT) and caloric restriction (-25%, fat reduced) with adequate supply of micronutrients affect DNA-damage in peripheral leukocytes, antioxidant parameters in plasma, and T-cell apoptosis. Material & Methods: 10 healthy male non-smokers were subjected to 4 different interventions (normocaloric diet or caloric restriction (CR) in upright position (UP) or HDT) for 14 days each (cross-over). DNA-damage in peripheral leukocytes (Comet Assay), trolox equivalent antioxidant capacity (TEAC) and uric acid in plasma were measured before, after 5, 10, and 13 days of intervention, and after 2 days recovery. T-cell apoptosis (Annexin V binding test) was assessed before and after intervention. Results: Preliminary results show that only endogenous, but not ex vivo H2O2-induced DNA strand breaks were reduced by CR compared to normocaloric diet. In upright position, endogenous DNA strand breaks decreased continuously during CR, reaching significance after recovery. During HDT, caloric restriction seems to counteract a temporary increase in DNA strand breaks observed in subjects receiving normocaloric diet. TEAC was reduced during HDT compared to UP in subjects under caloric restriction. An increase in plasma uric acid related to intervention occurred only after 5 days HDT in CR vs. normocaloric diet. T-cell apoptosis was not affected by any kind of intervention. Conclusion: Neither HDT nor CR with sufficient supply of micronutrients seem to induce oxidative stress or T-cell apoptosis in healthy young men. In contrast, CR might prevent endogenous DNA-damage in peripheral leukocytes. As DNA-damage is a risk factor for carcinogenesis, protective effects of energy reduction are

Weight loss-induced improvements in basal and postprandial IS were associated with decreases in leptin and increases in ghrelin levels, respectively (r = 0.36 and r = 0.62, p<0.05. Weight regain-induced decrease in postprandial IS correlated with increases in adiponectin, fT3, TSH, GL of the diet and a decrease in ghrelin levels (r-values between -0.40 and 0.83, p<0.05 whereas increases in early and total insulin secretion were associated with a decrease in leptin/adiponectin-ratio (r = -0.52 and r = -0.46, p<0.05 and a decrease in fT4 (r = -0.38, p<0.05 for total insulin secretion only. After controlling for GL associations between RF-induced decrease in postprandial IS and increases in fT3 and TSH levels were no longer significant.Weight cycling induced changes in IS and insulin secretion were associated with changes in all measured hormones, except for catecholamine excretion. While leptin, adiponectin and ghrelin seem to be the major

    Background. Concerns about potential adverse effects of testosterone on prostate have motivated the development of selective androgen receptor modulators that display tissue-selective activation of androgenic signaling. LGD-4033, a novel nonsteroidal, oral selective androgen receptor modulator, binds androgen receptor with high affinity and selectivity. Objectives. To evaluate the safety, tolerability, pharmacokinetics, and effects of ascending doses of LGD-4033 administered daily for 21 days on lean body mass, muscle strength, stair-climbing power, and sex hormones. Methods. In this placebo-controlled study, 76 healthy men (21–50 years) were randomized to placebo or 0.1, 0.3, or 1.0 mg LGD-4033 daily for 21 days. Blood counts, chemistries, lipids, prostate-specific antigen, electrocardiogram, hormones, lean and fat mass, and muscle strength were measured during and for 5 weeks after intervention. Results. LGD-4033 was well tolerated. There were no drug-related serious adverse events. Frequency of adverse events was similar between active and placebo groups. Hemoglobin, prostate-specific antigen, aspartate aminotransferase, alanine aminotransferase, or QT intervals did not change significantly at any dose. LGD-4033 had a long elimination half-life and dose-proportional accumulation upon multiple dosing. LGD-4033 administration was associated with dose-dependent suppression of total testosterone, sex hormone–binding globulin, high density lipoprotein cholesterol, and triglyceride levels. follicle-stimulating hormone and free testosterone showed significant suppression at 1.0-mg dose only. Lean body mass increased dose dependently, but fat mass did not change significantly. Hormone levels and lipids returned to baseline after treatment discontinuation. Conclusions. LGD-4033 was safe, had favorable pharmacokinetic profile, and increased lean body mass even during this short period without change in prostate-specific antigen. Longer randomized trials should

    The aim was to investigate the ability of an erythropoiesis-stimulating agent (ESA), alone or in combination with endurance training, to induce changes in human skeletal muscle fibre and vascular morphology. In a comparative study, 36 healthy untrained men were randomly dispersed into the following four groups: sedentary-placebo (SP, n = 9); sedentary-ESA (SE, n = 9); training-placebo (TP, n = 10); or training-ESA (TE, n = 8). The ESA or placebo was injected once weekly. Training consisted of progressive bicycling three times per week for 10 weeks. Before and after the intervention period, muscle biopsies and magnetic resonance images were collected from the thigh muscles, blood was collected, body composition measured and endurance exercise performance evaluated. The ESA treatment (SE and TE) led to elevated haematocrit, and both ESA treatment and training (SE, TP and TE) increased maximal O2 uptake. With regard to skeletal muscle morphology, TP alone exhibited increases in whole-muscle cross-sectional area and fibre diameter of all fibre types. Also exclusively for TP was an increase in type IIa fibres and a corresponding decrease in type IIx fibres. Furthermore, an overall training effect (TP and TE) was statistically demonstrated in whole-muscle cross-sectional area, muscle fibre diameter and type IIa and type IIx fibre distribution. With regard to muscle vascular morphology, TP and TE both promoted a rise in capillary to muscle fibre ratio, with no differences between the two groups. There were no effects of ESA treatment on any of the muscle morphological parameters. Despite the haematopoietic effects of ESA, we provide novel evidence that endurance training rather than ESA treatment induces adaptational changes in angiogenesis and muscle morphology.

    [Purpose] The aim of the present study was to investigate the acute effects of unilateral whole body vibration training on height and symmetry of the single leg vertical jump in healthy men. [Subjects] Thirty males with no history of lower limb dysfunction participated in this study. [Methods] The participants were randomly allocated to one of three groups: the unilateral vibratory stimulation group (n=10), bilateral vibratory stimulation group (n=10), and, no vibratory stimulation group (n=10). The subjects in the unilateral and bilateral stimulation groups participated in one session of whole body vibration training at 26 Hz for 3 min. The no vibratory stimulation group subjects underwent the same training for 3 min without whole body vibration. All participants performed the single leg vertical jump for each lower limb, to account for the strong and weak sides. The single leg vertical jump height and symmetry were measured before and after the intervention. [Results] The single leg vertical jump height of the weak lower limb significantly improved in the unilateral vibratory stimulation group, but not in the other groups. The single leg vertical jump height of the strong lower limb significantly improved in the bilateral vibratory stimulation group, but not in the other groups. The single leg vertical jump symmetry significantly improved in the unilateral vibratory stimulation group, but not in the other groups. [Conclusion] Therefore, the present study found that the effects of whole body vibration training were different depending on the type of application. To improve the single leg vertical jump height in the weak lower limbs as well as limb symmetry, unilateral vibratory stimulation might be more desirable.

  16. Cortisol responses to mental stress and the progression of coronary artery calcification in healthy men and women.

    Full Text Available BACKGROUND: Psychosocial stress is a risk factor for coronary heart disease (CHD. The mechanisms are incompletely understood, although dysfunction of the hypothalamic pituitary adrenal (HPA axis might be involved. We examined the association between cortisol responses to laboratory-induced mental stress and the progression of coronary artery calcification (CAC. METHODS AND RESULTS: Participants were 466 healthy men and women (mean age = 62.7±5.6 yrs, without history or objective signs of CHD, drawn from the Whitehall II epidemiological cohort. At the baseline assessment salivary cortisol was measured in response to mental stressors, consisting of a 5-min Stroop task and a 5-min mirror tracing task. CAC was measured at baseline and at 3 years follow up using electron beam computed tomography. CAC progression was defined as an increase >10 Agatston units between baseline and follow up. 38.2% of the sample demonstrated CAC progression over the 3 years follow up. There was considerable variation in the cortisol stress response, with approximately 40% of the sample responding to the stress tasks with an increase in cortisol of at least 1 mmol/l. There was an association between cortisol stress reactivity (per SD and CAC progression (odds ratio = 1.27, 95% CI, 1.02-1.60 after adjustments for age, sex, pre-stress cortisol, employment grade, smoking, resting systolic BP, fibrinogen, body mass index, and use of statins. There was no association between systolic blood pressure reactivity and CAC progression (odds ratio per SD increase = 1.03, 95% CI, 0.85-1.24. Other independent predictors of CAC progression included age, male sex, smoking, resting systolic blood pressure, and fibrinogen. CONCLUSION: Results demonstrate an association between heightened cortisol reactivity to stress and CAC progression. These data support the notion that cortisol reactivity, an index of HPA function, is one of the possible mechanisms through which

    Full Text Available OBJECTIVES: Flexible poles can provide rapid eccentric and concentric muscle contractions. Muscle vibration is associated with a "tonic vibration reflex” that is stimulated by a sequence of rapid muscle stretching, activation of the muscle spindles and stimulation of a response that is similar to the myotatic reflex. Literature studies analyzing the acute cardiovascular responses to different exercises performed with this instrument are lacking. We investigated the acute effects of exercise with flexible poles on the heart period in healthy men. METHOD: The study was performed on ten young adult males between 18 and 25 years old. We evaluated the heart rate variability in the time and frequency domains. The subjects remained at rest for 10 min. After the rest period, the volunteers performed the exercises with the flexible poles. Immediately after the exercise protocol, the volunteers remained seated at rest for 30 min and their heart rate variability was analyzed. RESULTS: The pNN50 was reduced at 5-10 and 15-20 min after exercise compared to 25-30 min after exercise (p = 0.0019, the SDNN was increased at 25-30 min after exercise compared to at rest and 0-10 min after exercise (p = 0.0073 and the RMSSD was increased at 25-30 min after exercise compared to 5-15 min after exercise (p = 0.0043. The LF in absolute units was increased at 25-30 min after exercise compared to 5-20 min after exercise (p = 0.0184. CONCLUSION: A single bout of exercise with a flexible pole reduced the heart rate variability and parasympathetic recovery was observed approximately 30 min after exercise.

    1. The safety, tolerability, pharmacokinetics, pharmacodynamics, and food effect of LB30870, a new selective thrombin inhibitor, were studied in 16 healthy men. 2. A double-blind, placebo-controlled single ascending dose study was done at oral doses of 5, 15, 30, 60, 120, and 240 mg under fasting conditions. An open, randomized, balanced cross-over food effect study was done at 60 mg dose. Plasma and urinary concentrations were measured up to 48 h post-dose. Coagulation and thrombin activity markers were measured at selected time points. 3. Cmax of LB30870 was at 1.3-3.0 h post-dose with a mean apparent terminal half-life (t1/2) of 2.8-4.1 h. AUC after doses above 15 mg appeared greater than dose-proportional. In fed state, AUC showed 80% reduction relative to fasting condition. 4. At doses 60 and 120 mg, peak activated partial thromboplastin time (aPTT) increased by 1.5- and 2-fold, respectively, from baseline. The aPTT and international normalized ratio (INR) were concentration-dependent, with less within-individual variability than ecarin clotting time (ECT), prothrombin time (PT), or thrombin time (TT). 5. Single oral doses of LB30870 up to 240 mg were well tolerated. The food effect must be overcome if LB30870 is to be used as an oral anti-coagulant. PMID:25673087

    Meal-dependent fluctuations of blood glucose and corresponding endocrine signals such as insulin are thought to provide important regulatory input for central nervous processing of hunger and satiety. Since food intake also triggers the release of numerous gastrointestinal signals, the specific contribution of changes in blood glucose to appetite regulation in humans has remained unclear. Here we tested the hypothesis that inducing glycemic fluctuations by intravenous glucose infusion is associated with concurrent changes in hunger, appetite, and satiety. In a single blind, counter-balanced crossover study 15 healthy young men participated in two experimental conditions on two separate days. 500 ml of a solution containing 50 g glucose or 0.9% saline, respectively, was intravenously infused over a 1-h period followed by a 1-h observation period. One hour before start of the respective infusion subjects had a light breakfast (284 kcal). Blood glucose and serum insulin concentrations as well as self-rated feelings of hunger, appetite, satiety, and fullness were assessed during the entire experiment. Glucose as compared to saline infusion markedly increased glucose and insulin concentrations (peak glucose level: 9.7 ± 0.8 vs. 5.3 ± 0.3 mmol/l; t(14) = -5.159, p hunger, appetite satiety, and fullness did not differ from the control condition throughout the experiment. These findings clearly speak against the notion that fluctuations in glycemia and also insulinemia represent major signals in the short-term regulation of hunger and satiety.

    Heavy drinking causes hangover symptoms, because the action of alcohol dehydrogenase forms acetaldehyde, which is metabolized by acetaldehyde dehydrogenase into acetate. Red ginseng shows positive effects on alcohol metabolism in animal studies. We investigated the effects of red ginseng on relieving alcohol and hangover symptoms in 25 healthy men in a randomized crossover study. At each visit (0, 1, and 2 weeks), the subjects drank 100 mL whiskey (40% alcohol) and either 100 mL water or 100 mL of a 0.321 mg mL(-1) red ginseng anti-hangover drink (RGD). We took blood samples periodically until 240 min after alcohol consumption, and we investigated the blood profiles, alcohol levels, and acetaldehyde levels. We also measured anthropometric parameters, expiratory air-alcohol levels, and hangover symptoms. The plasma alcohol concentrations within the RGD group were significantly lower than those within the placebo group after 30 min (p = 0.002), 45 min (p = 0.016), and 60 min (p = 0.009); the areas under the response curves revealed a positive effect of RGD (p = 0.051). Furthermore, the expiratory alcohol concentration was significantly lower after 30 min (p = 0.005) and 60 min (p = 0.065), and the areas under the response curves (p = 0.058) likewise revealed a positive effect of RGD. The plasma acetaldehyde level was significantly elevated at 120 min (p = 0.020), but the areas under the response curves showed a similar trend (p = 0.054). While the plasma acetaldehyde concentration slightly increased, the RGD showed positive effects on hangover symptoms. Considering the reduction of plasma alcohol levels, expiratory concentrations, and hangover severity, we conclude that red ginseng relieves the symptoms of alcohol hangover. PMID:24458173

    The effects of resistance training on adiponectin have thus far yielded equivocal results. However, the effect of periodized resistance training on plasma adiponectin in offspring of type 2 diabetic and nondiabetic (ND) parents (first-degree family history) has yet to be determined. Untrained healthy young men with and without a first-degree family history of type 2 diabetes were assigned to an exercise intervention group (E) or an active control group (C). The E group performed a 12-week periodized resistance training program, whereas the C group did not participate in any structured exercise program. Fasting plasma samples were obtained pre- and posttraining. Total plasma adiponectin changed significantly in the E group (33.7 ± 14.7%, p = 0.025) but not in the C group (10.8 ± 19.2%). Offspring of type 2 diabetic parents subjects had significantly greater improvements in plasma adiponectin (69.3 ± 34.8%) compared with ND subjects (-3.2 ± 29.9%, p = 0.046). Regular aerobic exercise was significantly correlated with average plasma adiponectin (r = 0.32), whereas first-degree family history of type 2 diabetes (r = -0.58) and decreases in body fat percentage (r = -0.77) were inversely correlated with average plasma adiponectin. Periodized high-intensity resistance training seems to increase plasma adiponectin, particularly in individuals with a first-degree family history of type 2 diabetes or those who experience a significant loss of fat mass. The direct correlation between regular aerobic exercise and adiponectin further suggests that a combination of aerobic and resistance training yields greater improvements in plasma adiponectin compared with resistance training alone.

    Full Text Available Dyslipidemia and possibly lipid peroxidation play important roles in the development of macro- and microvascular disease in type 1 diabetes mellitus. Little is known, however, of the role of aerobic exercise in dyslipidemia and resting and exercise-induced lipid peroxidation in type 1 diabetes. Despite the well-known effect of leisure-time physical activity (LTPA on components of the metabolic syndrome, little is known of the association of LTPA and cardiorespiratory fitness (maximal oxygen consumption, VO2max with development of the metabolic syndrome itself. A randomized controlled trial assessing the effect of a 12-16 week aerobic exercise program on VO2max and the lipid profile was carried out in otherwise healthy young men with type 1 diabetes. The effect of acute physical exercise on oxidative stress and antioxidant defenses and the relation to VO2max in men with type 1 diabetes was also evaluated. To test four recently proposed definitions by the World Health Organization (WHO and National Cholesterol Education Program (NCEP of the metabolic syndrome, the sensitivity and specificity of the definitions for prevalent and incident diabetes were assessed in a population-based cohort of middle-aged men. We also studied the associations of LTPA and cardiorespiratory fitness with prevalent and incident cases of the metabolic syndrome. A 12-16 week endurance exercise program produced antiatherogenic changes in lipid, lipoprotein and apolipoprotein levels in 20 type 1 diabetic men who for the most part were already physically active at baseline. The most favorable training-induced changes in the high-density lipoprotein cholesterol (HDL/low-density lipoprotein cholesterol (LDL and apolipoprotein A-I/apolipoprotein B ratios were in patients with low baseline HDL/LDL levels, likely the group with the most benefit to be gained by such changes. Plasma thiobarbituric acid reactive substances (TBARS, a measure of lipid peroxidation, was higher in nine

  5. The serotonin-1A receptor distribution in healthy men and women measured by PET and [carbonyl-11C]WAY-100635

    International Nuclear Information System (INIS)

    The higher prevalence rates of depression and anxiety disorders in women compared to men have been associated with sexual dimorphisms in the serotonergic system. The present positron emission tomography (PET) study investigated the influence of sex on the major inhibitory serotonergic receptor subtype, the serotonin-1A (5-HT1A) receptor. Sixteen healthy women and 16 healthy men were measured using PET and the highly specific radioligand [carbonyl-11C]WAY-100635. Effects of age or gonadal hormones were excluded by restricting the inclusion criteria to young adults and by controlling for menstrual cycle phase. The 5-HT1A receptor BPND was quantified using (1) the 'gold standard' manual delineation approach with ten regions of interest (ROIs) and (2) a newly developed delineation method using a PET template normalized to the Montreal Neurologic Institute space with 45 ROIs based on automated anatomical labeling. The 5-HT1A receptor BPND was found equally distributed in men and women applying both the manual delineation method and the automated delineation approach. Women had lower mean BPND values in every region investigated, with a borderline significant sex difference in the hypothalamus (p=0.012, uncorrected). There was a high intersubject variability of the 5-HT1A receptor BPND within both sexes compared to the small mean differences between men and women. To conclude, when measured in the follicular phase, women do not differ from men in the 5-HT1A receptor binding. To explain the higher prevalence of affective disorders in women, further studies are needed to evaluate the relationship between hormonal status and the 5-HT1A receptor expression. (orig.)

    Immune gender differences have been reported, but are little studied in elderly humans. We compared monocyte and lymphocyte subsets, along with soluble immune mediators in healthy men and women over the age of 70. We also measured natural killer (NK) lymphocyte cytotoxic granule exocytosis, chemokine synthesis, and cytokine synthesis in response to a variety of stimuli. Elderly women had significantly more circulating B cells than men, whereas men had more CD4 central memory T cells and higher monocyte levels. Plasma adiponectin levels were higher in women, plasma retinol-binding protein 4 levels were higher in men, but there were no significant gender differences in C-reactive protein, IL-15, or sphingosine-1-phosphate. Women had a higher ratio of immature CD56(bright) NK cells to mature CD56(dim) NK cells, indicating a gender difference in NK cell maturation in the elderly. Comparing sexes, female mature NK cells had more vigorous cytotoxic granule responses to K562 leukemia cells and IFN-γ responses to NKp46 crosslinking. Moreover, female NK cells were more likely to produce MIP-1β in response to a variety of stimuli. These data show that gender influences NK cell activity in elderly humans. PMID:27059724

    Parabens are used as anti-microbial preservatives in a range of consumer products, especially in cosmetics. In vitro and animal studies have shown weak estrogenic and other endocrine disrupting effects of parabens, including reduced testosterone levels in exposed male rats. The knowledge of paraben...... exposure, distribution and excretion in humans is limited. In this study we determined the concentration of five parabens; methyl-, ethyl-, n-propyl-, n-butyl- and benzylparaben in urine, serum and seminal plasma samples from 60 healthy Danish men. To conduct the study a sensitive and specific method using...... LC-MS/MS for simultaneous determination of the five parabens was developed for all three different matrices. Highest concentrations of the parabens were found in urine, wherein methyl-, ethyl-, n-propyl- and n-butyl parabens were measurable in 98%, 80%, 98% and 83% of the men, respectively. Benzyl...

  9. "Moderate Stress Enhances Immediate and Delayed Retrieval of Educationally Relevant Material in Healthy Young Men": Correction to Hupbach and Fieman (2012).

    Science.gov (United States)

    2016-06-01

    Reports an error in "Moderate stress enhances immediate and delayed retrieval of educationally relevant material in healthy young men" by Almut Hupbach and Rachel Fieman (Behavioral Neuroscience, 2012[Dec], Vol 126[6], 819-825). In the article there are computational errors in the last sentence of the Memory Performance section. "(M = .30, SD = .11 for CPS, and M = .13, SD = 17 for the warm water control)." should read instead: "(M = .03, SD = .11 for CPS, and M = .13, SD = .17 for the warm water control)." (The following abstract of the original article appeared in record 2012-27908-001.) Retrieval practice is a powerful memory enhancer. However, in educational settings, test taking is often experienced as a stressful event. While it is known that stress can impair retrieval processes, little is known about the delayed consequences of testing memory for educationally relevant material under stressful conditions, which is the focus of the present study. Participants (38 women, 37 men) memorized a scientific text passage on Day 1. On Day 2, they were either exposed to a stressor (cold pressor test; CPS) or a warm water control, and immediately afterward, they were asked to recall the text passage (i.e., retrieval under stress vs. control). Salivary cortisol was measured as an index of the stress response before, and 20 min after the CPS versus control treatment. The delayed effects of testing under stress were assessed with a final recall test on Day 3. In comparison to the control condition, CPS caused significant increases in salivary cortisol, and, surprisingly resulted in enhanced memory in men. Importantly, this enhancement was not only observed in the test that immediately followed the stressor, but also in the delayed test. In women, CPS caused only marginal increases in cortisol concentrations, and retrieval remained unaffected. Our study suggests that moderate stress can improve memory performance for educationally relevant material in a long-lasting manner

    Ejaculation disorders are associated with tamsulosin treatment for lower urinary tract symptoms suggestive of benign prostatic hyperplasia (BPH). To assess whether tamsulosin has any effect on semen, sperm parameters were evaluated in healthy men receiving tamsulosin, alfuzosin, and placebo. Forty-eight healthy men received 5 days of tamsulosin 0.8 mg once daily (QD), alfuzosin 10 mg QD, and placebo in a randomized, double-blind, 3-way crossover study with a 10-14-day washout period between treatments. The changes (x +/- SE) from baseline in semen sperm concentration, semen sperm count, semen viscosity, semen fructose, sperm motility, and sperm morphology on day 5 of treatment were assessed. The change from baseline in semen sperm concentration was 3.1 +/- 8.3 million/mL with tamsulosin, 15.0 +/- 6.5 million/mL with alfuzosin, and 24.4 +/- 6.5 million/mL with placebo. The total sperm count in semen decreased from baseline with tamsulosin (-54.6 +/- 24.0 million) but not with placebo (81.5 +/- 18.8 million) or alfuzosin (46.2 +/- 19.0 million). The percentage of men with normal semen viscosity was lower with tamsulosin (65%) than with placebo (98%) or alfuzosin (92%). The change from baseline in semen fructose was comparable for all treatments. The percentage of motile sperm decreased 13.8% from baseline to day 5 of treatment with tamsulosin compared with decreases of 2.3% with placebo and 0.4% with alfuzosin. The percentage of abnormal sperm increased marginally with tamsulosin (0.6%) but not with placebo (-2.8%) or alfuzosin (-3.9%). The most common adverse events were dizziness (alfuzosin 11%, tamsulosin 14%, placebo 0%) and orthostatic hypotension (alfuzosin 25%, tamsulosin 11%, placebo 5%). The results suggest that tamsulosin has a negative effect on sperm in healthy men. Studies on the effects of alpha(1)-adrenergic blockers on sperm in men with BPH are warranted. PMID:19201696

    Rye is an important source of plant lignans in Finland. In the present crossover trial we wanted to study the effect of rye bread as part of the usual diet on serum and urine enterolactone (ENL) concentrations in healthy volunteers. Eighteen men aged 43 (sem 2.0) years and twenty-one women aged 43 (sem 1.6) years consumed wholemeal rye bread and white wheat bread in random order for 4 weeks. The bread periods were separated by a 4 week wash-out period. The breads provided at least 20% of the daily energy intake. The mean intakes of rye bread were 219 (sem 14.6) and 162 (sem 5.3) g/d and those of wheat bread were 200 (sem 9.6) and 153 (sem 5.8) g/d for men and women respectively. Blood samples were collected from all subjects and three 24 h urine samples were collected from ten men and twelve women at the end of both bread periods for the determination of serum concentration and urinary excretion of ENL. The mean serum ENL concentrations in both men and women at the beginning of baseline period and at the end of the rye-bread period remained constant and were significantly higher than those at the end of the wheat-bread period. Correspondingly, daily urinary ENL excretion increased significantly during the rye-bread period compared with the wheat-bread period and was 5- and 10-fold higher in men and women respectively in comparison with the amount of plant lignan precursors measured in the rye bread. These data indicate the presence of other precursors for ENL in rye which are not detected by the current method of measuring plant lignans in food. The possible role of fibre in enhancement of the formation of mammalian lignans from their plant precursors in the gut also remains to be determined.

    Elevated resting heart rate (RHR) is known to be associated with reduced survival but inconsistencies remain, including lack of significance in most studies of healthy women, lack of independence from systolic blood pressure (SBP) in some, and the suggestion that RHR is merely functioning as a marker of physical inactivity or other comorbidities. We aimed to clarify these inconsistencies.

    Muscle pull and weight-bearing are key mechanical determinants of bone geometry which is an important feature of bone strength that declines with adult aging. However, the relative importance of these determinants in young and old adults has not been evaluated systematically. To differentiate the influence of each type of mechanical loading we compared humeral and femoral bone shaft geometry and cross-sectional area (CSA) of the arm and thigh muscles in young and old men. Contiguous transverse MRI (Siemens 1.5T) scans of the arm and thigh were made in 10 young men (21.9 ± 1.0 years) and 10 old men (78.1 ± 4.9 years). Image analysis yielded total (TA), cortical (CA) and medullary (MA) CSA of the humeral and femoral shafts, as well as muscle CSA of the corresponding regions of the arm and thigh. Humeral CA was significantly greater in the young, whereas humeral and femoral MA were significantly greater in the older group. Significant correlations were found between arm muscle CSA and humeral CA (r = 0.73); between thigh muscle CSA and femoral CA (r = 0.69); and between body mass and femoral CA (r = 0.63) and TA (r = 0.55). Moderate correlations between muscle CSA and CA suggest that muscle pull is an important determinant of bone geometry. The significant difference observed between young and old in humeral, but not femoral CA, and the correlation between body mass and femoral, but not humeral cortical area, suggests that weight-bearing attenuates bone loss associated with adult aging.

    Cardiovascular risk factors are known to exacerbate high-saturated fatty acid meal (HSFAM)-induced endothelial dysfunction, but the influence of subclinical metabolic dysregulations and the acute impact of a single mixed Mediterranean-type meal (MMM) remains unknown. Thus, this study has the objective to evaluate the metabolic and vascular effect of such meals in healthy subjects with or without subclinical fasting metabolic dysregulations. Twenty-eight healthy males without overt cardiovascular risk factors randomly ingested 1 of 2 isocaloric meals on separate days. Plasma metabolic markers, fatty acid (FA) profile, and endothelial function (flow-mediated dilatation; FMD) were assessed at baseline and 2 and 4 h after meal ingestion. Unsupervised hierarchical clustering identified 2 subgroups of participants (n = 11 and 17) differing by their baseline metabolic profiles. The MMM did not significantly alter postprandial endothelial function in all subjects, irrespective of baseline metabolic parameters. In contrast, the HSFAM induced postprandial endothelial dysfunction (Δ%FMDabsolute = -5.28 ± 2.54, p < 0.01 vs. MMM) in a subgroup of individuals with significantly greater body mass index, fasting insulinemia, and lipid parameters (n = 11). Finally, the postprandial plasma FA profiles were differentially enriched by the HSFAM and MMM, notably with saturated FAs and omega-3 polyunsaturated FAs, respectively. Collectively, our results highlight the detrimental impact of a single HSFAM on endothelial function in healthy individuals displaying subclinical fasting metabolic dysregulations. Such individuals could benefit from MMM, demonstrated herein to be without any acute detriment to endothelial function. PMID:27454855

    The aim of the study was to compare the effects of compound vs. complex resistance training on strength, high-speed movement performance, and muscle composition. Eighteen young men completed compound (strength and power sessions on alternate days) or complex training (strength and power sets within a single session) 3 times per week for 6 weeks using bench press, leg press, Smith machine box squat, and jumping exercises. Pre- and posttraining, jumping and throwing performance and maximum bench press, leg press, and Smith machine box squat strength were evaluated. The architecture of vastus lateralis and gastrocnemius muscle was assessed using ultrasound imaging. Vastus lateralis morphology was assessed from muscle biopsies. Jumping (4 ± 3%) and throwing (9 ± 8%) performance increased only with compound training (p power training on alternate days is more effective for enhancing lower-limb and whole-body power, whereas training on the same day may induce greater increases in strength and fiber hypertrophy.

    Full Text Available It is claimed that WBC (whole-body cryotherapy enhances the resistance of the human body, also thanks to the beneficial effect on the antioxidant system. Accordingly, this research aimed to evaluate the effect of a series of whole-body cryostimulations on the level of non-enzymatic antioxidants and the activity of antioxidant enzymes in healthy men. The study was carried out on 30 young and healthy men aged 27.8±6.1 years with average body mass index and peak oxygen consumption (46.34±6.15 ml kg(-1 •min(-1. The participants were daily exposed for 3 minutes to cryogenic temperatures (-130°C. Blood samples were obtained in the morning before cryostimulation, again 30 min after exposure and the following day in the morning, during the 1(st, 10(th and 20(th session. Analysis concerned changes in plasma concentrations of total protein, albumin, glucose, uric acid and ceruloplasmin, and the most important components of the antioxidant system in red blood cells: superoxide dismutase, catalase, glutathione peroxidase, glutathione reductase, reduced and oxidized glutathione. To assess the oxidative stress level the 8-isoprostane concentration in plasma was measured. The obtained results indicate that cryogenic temperatures in repeated daily treatments result in changes in the peroxidant and antioxidant status. These changes seem to depend on the number of cryostimulations. After 20 daily treatments there was an increase in SOD, SOD:CAT ratio, a decrease in the concentration of reduced and oxidized glutathione and in the activity of GPx. It could be possible that differences in the activity of GSSG-R after 20 treatments depended on the body mass index of participants.

    Men and women are known to react differently to stress. Thus, stress cardiomyopathy almost solely strikes women. Stress cardiomyopathy is suggested to relate to sex differences in catecholamine reaction. Left heart function during dobutamine stress is well described, but sex-specific inotropic and lusitropic response to abrupt termination of dobutamine stress is not. We aimed to investigate sex differences in left ventricular (LV) and atrial (LA) function during and after dobutamine stress. We enrolled 20 healthy elderly subjects (60-70 yr, 10 females) and measured their LV and LA volumes throughout the cardiac cycle by cardiac magnetic resonance imaging at rest, during dobutamine stress (15 μg·kg(-1)·min(-1)), 15 min after termination (T15), and 30 min after termination (T30) of dobutamine stress. We calculated LV ejection fractions, LV stroke volumes, LV peak filling rates, and LA passive, active, and conduit volumes. Sex differences were not observed at rest or during dobutamine stress. Compared with prestress values, at T15 a rebound decrease in LV peak filling rate was observed in women (-22 ± 3%, P causes greater stress to the female heart. This is revealed after termination of dobutamine stress where the left heart recovers in men, whereas women experience rebound LV stiffening with reduced diastolic relaxation. This is the first report of a sex-specific transient rebound phenomenon in cardiovascular response to catecholamines.

    This study compared satiety after high protein pasta (16 g protein, 6 g fiber), high fiber pasta (11 g protein, 8 g fiber) or control pasta (11 g protein, 6 g fiber) in a randomized, placebo-controlled, double-blind crossover trial. Participants were 36 healthy and men and women from the University of Minnesota campus. Fasted men and women ate calorie controlled, but macronutrient different pastas at 12:00 pm along with 500 mL of water. The primary outcome was satiety assessed by Visual Analogue Scales at 0, 15, 30, 45, 60, 90, 120, and 180 min daily after consuming the pastas. Secondary outcomes were calories consumed at an ad libitum snack at 3:00 pm, calories from food intake, gastrointestinal tolerance, and palatability. No differences were found among the pasta treatments for satiety, snacking, or gastrointestinal tolerance. Men ate significantly more calories for the rest of the (P = 0.007) after the high protein pasta versus the high fiber pasta (1701 ± 154 compared with 1083 ± 154) with control pasta being intermediate to the other treatments. No significant differences were found for gastrointestinal tolerance, but the palatability ratings showed the high protein pasta was less tasty (P = 0.03) and less pleasant (P = 0.01) than the other 2 pastas. Satisfaction was positively associated with pleasantness and negatively associated with aftertaste. Our results do not support the idea that high protein or high fiber pasta produces a greater satiety response compared to pasta with lower amounts of either nutrient. It is likely that since pasta is already a very satiating food, the subjects were unable to differentiate between the 3 conditions.

    Full Text Available The purpose of the present study was to evaluate the effects of aerobic physical training (APT on heart rate variability (HRV and cardiorespiratory responses at peak condition and ventilatory anaerobic threshold. Ten young (Y: median = 21 years and seven middle-aged (MA = 53 years healthy sedentary men were studied. Dynamic exercise tests were performed on a cycloergometer using a continuous ramp protocol (12 to 20 W/min until exhaustion. A dynamic 24-h electrocardiogram was analyzed by time (TD (standard deviation of mean R-R intervals and frequency domain (FD methods. The power spectral components were expressed as absolute (a and normalized units (nu at low (LF and high (HF frequencies and as the LF/HF ratio. Control (C condition: HRV in TD (Y: 108, MA: 96 ms; P<0.05 and FD - LFa, HFa - was significantly higher in young (1030; 2589 ms²/Hz than in middle-aged men (357; 342 ms²/Hz only during sleep (P<0.05; post-training effects: resting bradycardia (P<0.05 in the awake condition in both groups; VO2 increased for both groups at anaerobic threshold (P<0.05, and at peak condition only in young men; HRV in TD and FD (a and nu was not significantly changed by training in either groups. The vagal predominance during sleep is reduced with aging. The resting bradycardia induced by short-term APT in both age groups suggests that this adaptation is much more related to intrinsic alterations in sinus node than in efferent vagal-sympathetic modulation. Furthermore, the greater alterations in VO2 than in HRV may be related to short-term APT.

    To preliminarily assess the acute effects of a single warm -water bath (WWB) on serum adipokine activity, we measured serum adiponectin, leptin and other metabolic profiles before, immediately after and 30 minutes after WWB in seven healthy male volunteers (mean age, 39.7 ± 6.0 years; mean body mass index, 21.6 ± 1.8 kg/m2). The subjects were immersed in tap water at 41°C for 10 minutes. Two weeks later, the same subjects underwent a single WWB with a bath additive that included inorganic salts and carbon dioxide (WWB with ISCO2) by the same protocol as for the first WWB. Leptin levels significantly increased immediately after WWB with tap water and ISCO2 (both P Adiponectin levels showed a slight, but not significant, increase both immediately after and 30 minutes after WWB with tap water or ISCO2. Some parameters, such as serum total cholesterol, red blood cell count, hemoglobin and hematocrit significantly increased immediately after WWB with tap water or ISCO2 (all P adiponectin profiles in healthy men.

    A high intake of saturated fat and of trans isomers of unsaturated fat is associated with increased risk of cardiovascular disease. Recently, we found that replacement of saturated fat by trans fat in a dietary controlled study with 32 men and women decreased serum high-density lipoprotein (HDL)-cholesterol and impaired endothelial function, suggesting that trans fats have stronger adverse effects than saturated fats. To investigate this further, we measured the activity of serum paraoxonase (PON1) in serum samples of the same volunteers after consumption of both diets. PON1 protects lipoproteins from oxidative damage, and higher PON1 activity appears to be related to lower cardiovascular disease risk. PON1 activity (mean +/- SD) was 195.9 +/- 108.9 U/L after 4 weeks of consuming a diet with 22.9% of energy (en%) from saturated fat and 184.5 +/- 99.3 U/L when 9.3 en% from saturated fat was replaced by trans fat (P =.006). Thus, replacement of dietary saturated fat by trans fat not only decreased serum HDL-cholesterol and impaired endothelial function, but also decreased the activity of serum paraoxonase. Whether the changes in serum paraoxonase activity caused the changes in endothelial function needs to be further investigated.

    Chronic sleep restriction (CSR) induces neurobehavioral deficits in young and healthy people with a morning failure of sustained attention process. Testing both the kinetic of failure and recovery of different cognitive processes (i.e., attention, executive) under CSR and their potential links with subject’s capacities (stay awake, baseline performance, age) and with some biological markers of stress and anabolism would be useful in order to understand the role of sleep debt on human behavior. Twelve healthy subjects spent 14 days in laboratory with 2 baseline days (B1 and B2, 8 h TIB) followed by 7 days of sleep restriction (SR1-SR7, 4 h TIB), 3 sleep recovery days (R1–R3, 8 h TIB) and two more ones 8 days later (R12–R13). Subjective sleepiness (KSS), maintenance of wakefulness latencies (MWT) were evaluated four times a day (10:00, 12:00 a.m. and 2:00, 4:00 p.m.) and cognitive tests were realized at morning (8:30 a.m.) and evening (6:30 p.m.) sessions during B2, SR1, SR4, SR7, R2, R3 and R13. Saliva (B2, SR7, R2, R13) and blood (B1, SR6, R1, R12) samples were collected in the morning. Cognitive processes were differently impaired and recovered with a more rapid kinetic for sustained attention process. Besides, a significant time of day effect was only evidenced for sustained attention failures that seemed to be related to subject’s age and their morning capacity to stay awake. Executive processes were equally disturbed/recovered during the day and this failure/recovery process seemed to be mainly related to baseline subject’s performance and to their capacity to stay awake. Morning concentrations of testosterone, cortisol and α-amylase were significantly decreased at SR6-SR7, but were either and respectively early (R1), tardily (after R2) and not at all (R13) recovered.

    Enzyme-treated asparagus extract (ETAS) has been developed as a novel anti-stress functional food ingredient that is produced from asparagus. Two human intervention trials with ETAS were conducted in healthy adult male volunteers. Study 1 was a randomized, double-blind, placebo-controlled study to assess the effects of ETAS on expression of heat shock protein 70 (HSP70) mRNA in blood and the autonomic nervous system (ANS). The ETAS group showed a tendency to enhance HSP70 mRNA expression level compared to the placebo group. Several ANS condition parameters were significantly improved in the ETAS group when compared to the placebo group. In Study 2, a randomized, double-blind, placebo-controlled, crossover trial investigated the influence on stress-related hormones and sleep. Serum and salivary cortisol levels were significantly elevated compared to baseline during the placebo period, but remained unchanged during the ETAS period. The salivary chromogranin A level was significantly decreased in the ETAS-treated subjects compared to their baseline levels. The actual sleep time was not significantly different between ETAS and placebo. However, when the subjects were divided into two categories based on sleep efficiency or the average of night sleeping time, ETAS intake was effective to modulate the sleep state among those with low sleep efficiency or excess sleep time.

    Although exercise regimens vary in content and duration, few studies have compared the caloric expenditure of multiple exercise modalities with the same duration. The purpose of this study was to compare the energy expenditure of single sessions of resistance, aerobic, and combined exercise with the same duration. Nine recreationally active men (age: 25 ± 7 years; height: 181.6 ± 7.6 cm; weight: 86.6 ± 7.5 kg) performed the following 4 exercises for 30 minutes: a resistance training session using 75% of their 1-repetition maximum (1RM), an endurance cycling session at 70% maximum heart rate (HRmax), an endurance treadmill session at 70% HRmax, and a high-intensity interval training (HIIT) session on a hydraulic resistance system (HRS) that included repeating intervals of 20 seconds at maximum effort followed by 40 seconds of rest. Total caloric expenditure, substrate use, heart rate (HR), and rating of perceived exertion (RPE) were recorded. Caloric expenditure was significantly (p ≤ 0.05) greater when exercising with the HRS (12.62 ± 2.36 kcal·min), compared with when exercising with weights (8.83 ± 1.55 kcal·min), treadmill (9.48 ± 1.30 kcal·min), and cycling (9.23 ± 1.25 kcal·min). The average HR was significantly (p ≤ 0.05) greater with the HRS (156 ± 9 b·min), compared with that using weights (138 ± 16 b·min), treadmill (137 ± 5 b·min), and cycle (138 ± 6 b·min). Similarly, the average RPE was significantly (p ≤ 0.05) higher with the HRS (16 ± 2), compared with that using weights (13 ± 2), treadmill (10 ± 2), and cycle (11 ± 1). These data suggest that individuals can burn more calories performing an HIIT session with an HRS than spending the same amount of time performing a steady-state exercise session. This form of exercise intervention may be beneficial to individuals who want to gain the benefits of both resistance and cardiovascular training but have limited time to dedicate to exercise.

    Observational studies suggest there are clinical benefits to moderate red wine (RW) consumption. However, the effects on coronary vasculature and overall lifestyle are unclear. We investigated whether a lifestyle of regular long-term RW consumption is associated with changes in coronary plaque burden, calcium score, carotid intima/media thickness, endothelial function, and metabolic variables, compared with alcohol abstinence. Healthy volunteers were evaluated by coronary computed tomography angiography (CTA) as well as carotid and brachial artery ultrasound. Nutritional status, psychological status, and metabolic variables were assessed. The study included 101 drinkers [aged 58.9 ± 7.3 years (means ± SD)], from wine brotherhoods, and 104 abstainers, from Anglican, Evangelical and Catholic churches both in the city of São Paulo, Brazil. No significant differences in demographics were noted. Lesion prevalence per patient assessed by coronary CTA and classified as absent (0), 1-25, 26-49, and ≥ 50% stenosis was similar between groups. When analyzed by individual arteries, i.e., left anterior descending, circumflex, and right coronary, prevalence was also not different. On the other hand, calcium scores were higher among drinkers than abstainers (144.4 ± 362.2 vs 122.0 ± 370.3; Phistory of diabetes and exercised more. RW drinkers consumed 2127.9 ± 387.7 kcal/day while abstainers consumed 1836.0 ± 305.0 (Pwine drinkers displayed a similar plaque burden but greater calcium score than abstainers, despite a more atherogenic diet, and the mechanisms for the increased calcium scores in the former remain speculative.

    Objective: To investigate the changes of autonomic nervous system (ANS) function during the initial phase at acute high-altitude exposure. Methods: Ninety-nine healthy sea-level male residents were studied in Chengdu plain and then Tibet plateau. Heart rate variability (HRV), cold pressor test (CPT), resting heart rate (HR) and blood pressure (BP) were measured at baseline (560 m altitude) and in 2 to 4 d after arriving at Tibet plateau (3 675 m altitude) to assess the ANS function. Results: Compared with baseline, on day 2 in Tibet the standard deviation of normal to normal intervals (SDNN), high-frequency (HF) power, total power (TP), root mean square of delta RR (rMSSD), percentage of delta RR>50 ms (PNN50), normalized high-frequency (Hfnu) and fractal dimension (FD) decreased significantly (SDNN, HF,TP P<0.01, rMSSD, PNNs0, Hfnu, FD P<0.05), while the normalized low-frequency (Lfnu) and LF/HF increased significantly (P<0.01). During day 3-4 in Tibet, SDNN, rMSSD, HF, TP and Hfnu tended to rebound while Lfnu and LF/HF decreased towards baseline day by day. In addition, in Tibet the increase in systolic pressure (SP) and diastolic pressure (DP) during CPT decreased significantly (P<0.01, 0.05), but resting HR increased compared with baseline (P<0.01). Conclusion: ANS modulation is generally blunted, and the relatively predominant sympathetic control is enhanced originally, then it reverts to the sea level states gradually during the initial days of acute high-altitude exposure.

    The aim of the paper was to follow up major physiological reactions, provoked by heat stress during dry and wet sauna baths. A physical strain index and subjective estimation of heat comfort of subjects who had not taken sauna baths before was also evaluated. Ten healthy males aged 25-28 underwent a dry sauna bath and then after a one-month break they underwent a steam sauna bath. Each time, they entered the sauna chamber 3 times for 15 minutes with five-minute breaks. During breaks they cooled their bodies with a cold shower and then rested in a sitting position. Before and after the baths, body mass and blood pressure were measured. Rectal temperature and heart rate were monitored during the baths. The physiological strain index (PSI) and cumulative heat strain index (CHSI) were calculated. Subjects assessed heat comfort by Bedford's scale. Greater body mass losses were observed after the dry sauna bath compared to the wet sauna (-0.72 vs. -0.36 kg respectively). However, larger increases in rectal temperature and heart rate were observed during the wet sauna bath (38.8% and 21.2% respectively). Both types of sauna baths caused elevation of systolic blood pressure, but changes were greater after the dry one. Diastolic pressure was reduced similarly. Subjective feelings of heat comfort as well as PSI (4.83 ± 0.29 vs. 5.7 ± 0.28) and CHSI (76.3 ± 18.4 vs. 144.6 ± 21.7) were greater during the wet sauna bath. It can be concluded that due to high humidity and reduction of thermoregulation mechanisms, the wet sauna is more stressful for the organism than the dry sauna, where the temperature is higher with low humidity. Both observed indexes (PSI and CHSI) could be appropriate for objective assessment of heat strain during passive heating of the organism.

    Low selenium levels have been linked to a higher incidence of cancer and other diseases, including Keshan, Chagas, and Kashin-Beck, and insulin resistance. Additionally, muscle and cardiovascular disorders, immune dysfunction, cancer, neurological disorders, and endocrine function have been associated with mutations in genes encoding for selenoproteins. Selenium biology is complex, and a systems biology approach to study global metabolomics, genomics, and/or proteomics may provide important clues to examining selenium-responsive markers in circulation. In the current investigation, we applied a global proteomics approach on plasma samples collected from a previously conducted, double-blinded placebo controlled clinical study, where men were supplemented with selenized-yeast (Se-Yeast; 300 μg/day, 3.8 μmol/day) or placebo-yeast for 48 weeks. Proteomic analysis was performed by iTRAQ on 8 plasma samples from each arm at baseline and 48 weeks. A total of 161 plasma proteins were identified in both arms. Twenty-two proteins were significantly altered following Se-Yeast supplementation and thirteen proteins were significantly changed after placebo-yeast supplementation in healthy men. The differentially expressed proteins were involved in complement and coagulation pathways, immune functions, lipid metabolism, and insulin resistance. Reconstruction and analysis of protein-protein interaction network around selected proteins revealed several hub proteins. One of the interactions suggested by our analysis, PHLD-APOA4, which is involved in insulin resistance, was subsequently validated by Western blot analysis. Our systems approach illustrates a viable platform for investigating responsive proteomic profile in 'before and after' condition following Se-Yeast supplementation. The nature of proteins identified suggests that selenium may play an important role in complement and coagulation pathways, and insulin resistance. PMID:27027327

    Biomarkers of chronic cell hydration status are needed to determine whether chronic hyperosmotic stress increases chronic disease risk in population-representative samples. In vitro, cells adapt to chronic hyperosmotic stress by upregulating protein breakdown to counter the osmotic gradient with higher intracellular amino acid concentrations. If cells are subsequently exposed to hypo-osmotic conditions, the adaptation results in excess cell swelling and/or efflux of free amino acids. This study explored whether increased red blood cell (RBC) swelling and/or plasma or urine amino acid concentrations after hypo-osmotic challenge might be informative about relative chronic hyperosmotic stress in free-living men. Five healthy men (20-25 years) with baseline total water intake below 2 L/day participated in an 8-week clinical study: four 2-week periods in a U-shaped A-B-C-A design. Intake of drinking water was increased by +0.8 ± 0.3 L/day in period 2, and +1.5 ± 0.3 L/day in period 3, and returned to baseline intake (0.4 ± 0.2 L/day) in period 4. Each week, fasting blood and urine were collected after a 750 mL bolus of drinking water, following overnight water restriction. The periods of higher water intake were associated with significant decreases in RBC deformability (index of cell swelling), plasma histidine, urine arginine, and urine glutamic acid. After 4 weeks of higher water intake, four out of five participants had ½ maximal RBC deformability below 400 mmol/kg; plasma histidine below 100 μmol/L; and/or undetectable urine arginine and urine glutamic acid concentrations. Work is warranted to pursue RBC deformability and amino acid concentrations after hypo-osmotic challenge as possible biomarkers of chronic cell hydration. PMID:24303184

  6. Coronary artery plaque burden and calcium scores in healthy men adhering to long-term wine drinking or alcohol abstinence

    International Nuclear Information System (INIS)

    Observational studies suggest there are clinical benefits to moderate red wine (RW) consumption. However, the effects on coronary vasculature and overall lifestyle are unclear. We investigated whether a lifestyle of regular long-term RW consumption is associated with changes in coronary plaque burden, calcium score, carotid intima/media thickness, endothelial function, and metabolic variables, compared with alcohol abstinence. Healthy volunteers were evaluated by coronary computed tomography angiography (CTA) as well as carotid and brachial artery ultrasound. Nutritional status, psychological status, and metabolic variables were assessed. The study included 101 drinkers [aged 58.9±7.3 years (means±SD)], from wine brotherhoods, and 104 abstainers, from Anglican, Evangelical and Catholic churches both in the city of São Paulo, Brazil. No significant differences in demographics were noted. Lesion prevalence per patient assessed by coronary CTA and classified as absent (0), 1-25, 26-49, and ≥50% stenosis was similar between groups. When analyzed by individual arteries, i.e., left anterior descending, circumflex, and right coronary, prevalence was also not different. On the other hand, calcium scores were higher among drinkers than abstainers (144.4±362.2 vs 122.0±370.3; P<0.01). However, drinkers reported less history of diabetes and exercised more. RW drinkers consumed 2127.9±387.7 kcal/day while abstainers consumed 1836.0±305.0 (P<0.0001). HDL cholesterol was significantly higher among drinkers compared to abstainers (46.9±10.9 vs 39.5±9.0 mg/dL; P<0.001), while fasting plasma glucose was lower (97.6±18.2 vs 118.4±29.6 mg/dL; P<0.02). Liver enzymes were normal in both groups. In conclusion, long-term wine drinkers displayed a similar plaque burden but greater calcium score than abstainers, despite a more atherogenic diet, and the mechanisms for the increased calcium scores in the former remain speculative

    Full Text Available This study examined the combined effects of aerobic exercise intensity and duration on serum brain-derived neurotrophic factor (sBDNF levels in healthy human adult males aged 18-25 years. Forty five participants were randomly assigned to one of six exercise conditions based on varying intensity (80% or 60% of heart rate reserve, or control and duration (20 or 40 min. Vigorous (80% heart rate reserve, "Vig" and moderate (60% heart rate reserve, "Mod" exercise was carried out on cycle ergometers. Control subjects remained seated and at rest during the exercise period. Pre- and post-exercise blood draws were conducted and sBDNF measured. Physical exercise caused an average ~ 32% increase in sBDNF levels relative to baseline that resulted in concentrations that were 45% higher than control conditions. Comparing the six conditions, sBDNF levels rose consistently among the four exercise conditions (Vig20 = 26.38 ± 34.89%, Vig40 = 28.48 ± 19.11%, Mod20 = 41.23 ± 59.65%, Mod40 = 30.16 ± 72.11% and decreased consistently among the controls (Con20 = -14.48 ± 16.50, Con40 = -10.51 ± 26.78. Vig conditions had the highest proportion of subjects that experienced a significant (> 10% increase in sBDNF levels, followed by Mod and control conditions. An analysis of modeled sBDNF integrals (area under the curve demonstrated substantially greater values for Vig40 and Mod40 conditions compared to Vig20 and Mod20 conditions. Collectively, these results demonstrate that neither duration (20 vs. 40 min nor intensity (60 vs. 80% HR reserve significantly affects the benefits of exercise if only the sBDNF increase at a single post-exercise time point is considered. However, when comparing either the probability of achieving a significant BDNF gain or the integral (i.e. the volume of circulating BDNF over time the Vig40 condition offers maximal benefits. Thus, we conclude that the future study of aerobic exercise effects on BDNF-mediated neuroprotection should take

Experimental design: Twenty-five healthy male volunteers aged 27–43 years were given 500 mg, 250 mg, and 125 mg of testosterone enanthate as single intramuscular doses of Testoviron® Depot. Luteinizing hormone (LH, follicle-stimulating hormone (FSH, blood lipid profile (total cholesterol, plasma [p-] low-density lipoprotein, p-high-density lipoprotein [HDL], p-apolipoprotein A1 [ApoA1], p-apolipoprotein B, p-triglycerides, p-lipoprotein(a, serum [s-] testosterone, and 25-hydroxyvitamin D3 were analyzed prior to, and 4 and 14 days after dosing. Testosterone and epitestosterone in urine (testosterone/epitestosterone ratio were analyzed prior to each dose after a washout period of 6–8 weeks. Results and discussion: All doses investigated suppressed the LH and FSH concentrations in serum. LH remained suppressed 6 weeks after the 500 mg dose. These results indicate that testosterone has a more profound endocrine effect on the hypothalamic–pituitary–gonadal axis than was previously thought. There was no alteration in 25-hydroxyvitamin D3 levels after testosterone administration compared to baseline levels. The 250 and 500 mg doses induced decreased concentrations of ApoA1 and HDL, whereas the lowest dose (125 mg did not have any effect on the lipid profile. Conclusion: The single doses of testosterone produced a dose-dependent increase in serum testosterone concentrations together with suppression of s-LH and s-FSH. Alterations in ApoA1 and HDL were observed after the two highest single doses. It is possible that long-time abuse of anabolic androgenic steroids will lead to alteration in vitamin D status

    A defect in auditory evoked potential (AEP) P50 gating supports the theory of information-processing deficits in schizophrenia. The relationship between gating of the mid-latency evoked potentials (EP) in the somatosensory and the auditory modalities has not been studied together before. In schizophrenia, we might expect the processing deficits to act on multiple modalities. We have examined the gating of median nerve somatosensory EP (SEP) following paired stimulation identical to the AEP P50 gating paradigm using interstimulus intervals (ISI) of 500, 750 and 1000 ms and the correlation of gating to the skin conductance orienting response (SCOR) in 20 healthy men. We measured mid-latency vertex components (SEP: P50, N65, P85 and N100; AEP: P30, N45, P50 and N80). The gating was most pronounced at ISI 500 ms where the SEP P50 and N100 gating were 0.59 and 0.37, respectively, as compared to a gating of 0.61 in P30, 0.33 in P50 and 0.45 in N80 in the AEP. Repetition effects in the two modalities were not correlated. AEP P50 gating was correlated to skin conductance level (SCL). The combination of recording repetition effects on the mid-latency EP in two modalities could provide a method for investigating if deficits of information processing in schizophrenia are cross-modal.

    We have previously identified pyloric pressures and plasma cholecystokinin (CCK) concentrations as independent determinants of energy intake following administration of intraduodenal lipid and intravenous CCK. We evaluated in healthy men whether these parameters also determine energy intake in response to intraduodenal protein, and whether, across the nutrients, any predominant gastrointestinal (GI) factors exist, or many factors make small contributions. Data from nine published studies, in which antropyloroduodenal pressures, GI hormones, and GI /appetite perceptions were measured during intraduodenal lipid or protein infusions, were pooled. In all studies energy intake was quantified immediately after the infusions. Specific variables for inclusion in a mixed-effects multivariable model for determination of independent predictors of energy intake were chosen following assessment for collinearity, and within-subject correlations between energy intake and these variables were determined using bivariate analyses adjusted for repeated measures. In models based on all studies, or lipid studies, there were significant effects for amplitude of antral pressure waves, premeal glucagon-like peptide-1 (GLP-1) and time-to-peak GLP-1 concentrations, GLP-1 AUC and bloating scores (P energy intake. In the model including the protein studies, only BPP was identified as an independent determinant of energy intake (P energy intake by lipid and protein, their contribution to the latter is much less. Moreover, the effects are likely to reflect small, cumulative contributions from a range of interrelated factors.

    Interval sprint exercise performed on a manually propelled treadmill, where the hands grip the handle bars, engages lower and upper limb skeletal muscle, but little is known regarding the effects of this exercise modality on the upper limb vasculature. We tested the hypotheses that an acute bout of sprint exercise and 6 weeks of training induces brachial artery (BA) and forearm vascular remodeling, favoring a more compliant system. Before and following a single bout of exercise as well as 6 weeks of training three types of vascular properties/methodologies were examined in healthy men: (1) stiffness of the entire upper limb vascular system (pulse wave velocity (PWV); (2) local stiffness of the BA; and (3) properties of the entire forearm vascular bed (determined by a modified lumped parameter Windkessel model). Following sprint exercise, PWV declined (P Sprint exercise induced a more compliant forearm vascular bed, without altering indices of BA stiffness. These effects were transient, as following training the forearm vascular bed was not more compliant and indices of BA stiffness increased. On the basis of these data, we conclude that adaptations to acute and chronic sprint exercise on a manually propelled treadmill are not uniform along the arterial tree in upper limb.

    Postprandial hyperglycemia induces prolonged hyperinsulinemia, which is a risk factor for type 2 diabetes mellitus. Foods with a low glycemic index blunt the rapid rise in postprandial plasma glucose and insulin levels. We herein investigated the effects of a novel, palatinose-based liquid diet (Inslow, Meiji Dairy Products, Tokyo, Japan) on postprandial plasma glucose and insulin levels and on the rate of substrate oxidation in 7 healthy men. Furthermore, to examine the effects of Inslow on the second-meal effect, we quantified our subjects' postprandial plasma glucose, insulin, and free fatty acid levels for up to 7 hours after they ingested a breakfast containing Inslow or control formula, followed by a standard lunch 5 hours later. Our results showed that peak plasma glucose and insulin levels 30 minutes after Inslow loading were lower than after control formula loading. Postprandial fat oxidation rates in the Inslow group were higher than in the control formula group (P consumption of Inslow at breakfast appears to improve patient glycemic control by reducing their postprandial plasma glucose and insulin levels after lunch (second-meal effect).

    Full Text Available Increased concentrations of circulating insulin-like growth factor-I (IGF-I or IGF-I relative to IGF-binding proteins (IGFBPs are associated with increased risk of developing several forms of cancer. Conversely, exercise is linked with reduced risk. This study aims to investigate the effect of a low-intensity exercise program on circulating levels of IGF-I, IGFBP-1, and IGFBP-3, in previously sedentary males. Fourteen healthy men participated in cycle ergometer training at lactate threshold intensity for 60 min/day, 5 days/week for 6 weeks. After aerobic training, insulin sensitivity improved by 20%, while fasting insulin levels decreased by 13%. Simultaneously, low-intensity aerobic training decreased the circulating levels of IGF-I by 9%, while IGFBP-1 levels increased by 16%. An interesting finding was that higher pretraining level of IGF-I was associated with greater decline in IGF-I with training. Insulin-sensitizing low-intensity aerobic exercise is thus considered to be an effective method for downregulating IGF-I and upregulating IGFBP-1 levels.

    Cocoa flavanol (CF) intake improves endothelial function in patients with cardiovascular risk factors and disease. We investigated the effects of CF on surrogate markers of cardiovascular health in low risk, healthy, middle-aged individuals without history, signs or symptoms of CVD. In a 1-month, open-label, one-armed pilot study, bi-daily ingestion of 450 mg of CF led to a time-dependent increase in endothelial function (measured as flow-mediated vasodilation (FMD)) that plateaued after 2 weeks. Subsequently, in a randomised, controlled, double-masked, parallel-group dietary intervention trial (Clinicaltrials.gov: NCT01799005), 100 healthy, middle-aged (35-60 years) men and women consumed either the CF-containing drink (450 mg) or a nutrient-matched CF-free control bi-daily for 1 month. The primary end point was FMD. Secondary end points included plasma lipids and blood pressure, thus enabling the calculation of Framingham Risk Scores and pulse wave velocity. At 1 month, CF increased FMD over control by 1·2 % (95 % CI 1·0, 1·4 %). CF decreased systolic and diastolic blood pressure by 4·4 mmHg (95 % CI 7·9, 0·9 mmHg) and 3·9 mmHg (95 % CI 6·7, 0·9 mmHg), pulse wave velocity by 0·4 m/s (95 % CI 0·8, 0·04 m/s), total cholesterol by 0·20 mmol/l (95 % CI 0·39, 0·01 mmol/l) and LDL-cholesterol by 0·17 mmol/l (95 % CI 0·32, 0·02 mmol/l), whereas HDL-cholesterol increased by 0·10 mmol/l (95 % CI 0·04, 0·17 mmol/l). By applying the Framingham Risk Score, CF predicted a significant lowering of 10-year risk for CHD, myocardial infarction, CVD, death from CHD and CVD. In healthy individuals, regular CF intake improved accredited cardiovascular surrogates of cardiovascular risk, demonstrating that dietary flavanols have the potential to maintain cardiovascular health even in low-risk subjects.

Sixty-nine participants were recruited and randomly assigned to one of three groups, of which sixty-four completed the study: a soccer training group (SOC; n = 20, 34±4 (means±SD years, 78.1±8.3 kg, 179±4 cm; a running group (RUN; n = 21, 32±4 years, 78.0±5.5 kg, 179±7 cm; or a passive control group (CON; n = 23, 30±3 years, 76.6±12.0 kg, 178±8 cm. The training intervention lasted 12 weeks and consisted of three 60-min sessions per week. All participants were tested for each of the following physical fitness components: maximal aerobic power, minute ventilation, maximal heart rate, squat jump (SJ, countermovement jump with arm swing (CMJ, sit-and-reach flexibility, and body composition. Over the 12 weeks, VO2max relative to body weight increased more (p<0.05 in SOC (24.2%, ES = 1.20 and RUN (21.5%, ES = 1.17 than in CON (-5.0%, ES = -0.24, partly due to large changes in body mass (-5.9, -5.7 and +2.6 kg, p<0.05 for SOC, RUN and CON, respectively.

    Full Text Available As studying with population carrying no classical cardiovascular risk factors seems to be an advantage in isolating effects of regular exercise on endothelial functions, inflammatory and thrombotic activity; the present study was designed to evaluate the clear effects of long-term regular exercise in middle-aged, healthy men. A total of 32 regularly exercising (three times per week, 12.8 ± 6.8 years men (Group I, mean age = 53.2 ± 6. 1 yrs and 32 sex- and age-matched sedentary subjects (Group II, mean age = 51.0 ± 7.7 yrs were involved in the study. All participants were non-smokers and with no history of hypertension and diabetes. During one day preceding tests, the subjects refrained from training and maintained their normal diet. In all subjects, body mass index (BMI, percentage of body fat (% BF and maximal oxygen uptake (VO2max were calculated. Serum uric acid, glucose, HbA1c, lipids, high-sensitive C-reactive protein (hs-CRP, fibrinogen levels, white blood cell (WBC and platelet count were measured. Resting heart rates and blood pressures were recorded and standard exercise stress test was applied using the modified Bruce protocol. Flow-mediated and nitrate-induced dilatation (FMD and NID of the brachial artery and carotid intima-media thickness (cIMT were evaluated as markers of endothelial functions and early atherosclerosis. Mean BMI, % BF, systolic and diastolic blood pressures, WBC and platelet count, HbA1c, total and LDL cholesterol, hs-CRP and fibrinogen levels were similar between the groups. Group I had significantly lower serum glucose, uric acid and triglyceride (p < 0.05, p < 0.005 and p < 0.05, respectively and higher HDL cholesterol levels (p < 0.0001 than in Group II. FMD values were significantly higher in Group I than in Group II (p < 0.005 while there were no significant differences in NID and cIMT measures between the groups. VO2max and cIMT showed a negative correlation in Group I (r = -0.463, p < 0.0001. Negative

    Savoie, FA, Asselin, A, and Goulet, EDB. Comparison of sodium chloride tablets-induced, sodium chloride solution-induced, and glycerol-induced hyperhydration on fluid balance responses in healthy men. J Strength Cond Res 30(10): 2880-2891, 2016-Sodium chloride solution-induced hyperhydration (NaCl-SolIH) is a powerful strategy to increase body water before exercise. However, NaCl-SolIH is associated with an unpleasant salty taste, potentially dissuading some athletes from using it and coaches from recommending it. Therefore, we evaluated the hyperhydrating potential of sodium chloride tablets-induced hyperhydration (NaCl-TabIH), which bypasses the palatability issue of NaCl-SolIH without sacrificing sodium chloride content, and compared it to NaCl-SolIH and glycerol-induced hyperhydration (GIH). Sixteen healthy males (age: 21 ± 2 years; fat-free mass (FFM): 65 ± 6 kg) underwent three, 3-hour long passive hyperhydration protocols during which they drank, over the first 60 minutes, 30-ml·kg FFM of an artificially sweetened solution. During NaCl-TabIH, participants swallowed 7.5, 1 g each, sodium chloride tablets with every liter of solution. During NaCl-SolIH, an equal quantity of sodium chloride tablets was dissolved in each liter of solution. With GIH, the glycerol concentration was 46.7 g·L. Urine production, fluid retention, hemoglobin, hematocrit, plasma volume, and perceptual variables were monitored throughout the trials. Total fluid intake was 1948 ± 182 ml. After 3 hour, there were no significant differences among treatments for hemoglobin, hematocrit, and plasma volume changes. Fluid retention was significantly greater with NaCl-SolIH (1150 ± 287 ml) than NaCl-TabIH (905 ± 340 ml) or GIH (800 ± 211 ml), with no difference between NaCl-TabIH and GIH. No differences were found among treatments for perceptual variables. NaCl-TabIH and GIH are equally effective, but inferior than NaCl-SolIH. NaCl-TabIH represents an alternative to hyperhydration induced

    Full Text Available Abstract Background Bradykinin type 2 receptor (B2BRK genotype was reported to be associated with changes in the left-ventricular mass as a response to aerobic training, as well as in the regulation of the skeletal muscle performance in both athletes and non-athletes. However, there are no reports on the effect of B2BRK 9-bp polymorphism on the response of the skeletal muscle to strength training, and our aim was to determine the relationship between the B2BRK SNP and triceps brachii functional and morphological adaptation to programmed physical activity in young adults. Methods In this 6-week pretest-posttest exercise intervention study, twenty nine healthy young men (21.5 ± 2.7 y, BMI 24.2 ± 3.5 kg/m2 were put on a 6-week exercise protocol using an isoacceleration dynamometer (5 times a week, 5 daily sets with 10 maximal elbow extensions, 1 minute rest between sets. Triceps brachii muscle volumes were assessed by using magnetic resonance imaging before and after the strength training. Bradykinin type 2 receptor 9 base pair polymorphism was determined for all participants. Results Following the elbow extensors training, an average increase in the volume of both triceps brachii was 5.4 ± 3.4% (from 929.5 ± 146.8 cm3 pre-training to 977.6 ± 140.9 cm3 after training, p9 allele compared to individuals with one or two +9 alleles (−9/-9, 8.5 ± 3.8%; vs. -9/+9 and +9/+9 combined, 4.7 ± 4.5%, p B2BRK genotype (−9/-9, 50.2 ± 19.2%; vs. -9/+9 and +9/+9 combined, 46.8 ± 20.7%, p > 0.05. Conclusions We found that muscle morphological response to targeted training – hypertrophy – is related to polymorphisms of B2BRK. However, no significant influence of different B2BRK genotypes on functional muscle properties after strength training in young healthy non athletes was found. This finding could be relevant, not only in predicting individual muscle adaptation capacity to training or sarcopenia related to aging and inactivity, but also in

    We have previously identified pyloric pressures and plasma cholecystokinin (CCK) concentrations as independent determinants of energy intake following administration of intraduodenal lipid and intravenous CCK. We evaluated in healthy men whether these parameters also determine energy intake in response to intraduodenal protein, and whether, across the nutrients, any predominant gastrointestinal (GI) factors exist, or many factors make small contributions. Data from nine published studies, in which antropyloroduodenal pressures, GI hormones, and GI /appetite perceptions were measured during intraduodenal lipid or protein infusions, were pooled. In all studies energy intake was quantified immediately after the infusions. Specific variables for inclusion in a mixed-effects multivariable model for determination of independent predictors of energy intake were chosen following assessment for collinearity, and within-subject correlations between energy intake and these variables were determined using bivariate analyses adjusted for repeated measures. In models based on all studies, or lipid studies, there were significant effects for amplitude of antral pressure waves, premeal glucagon-like peptide-1 (GLP-1) and time-to-peak GLP-1 concentrations, GLP-1 AUC and bloating scores (P < 0.05), and trends for basal pyloric pressure (BPP), amplitude of duodenal pressure waves, peak CCK concentrations, and hunger and nausea scores (0.05 < P ≤ 0.094), to be independent determinants of subsequent energy intake. In the model including the protein studies, only BPP was identified as an independent determinant of energy intake (P < 0.05). No single parameter was identified across all models, and effects of the variables identified were relatively small. Taken together, while GI mechanisms contribute to the regulation of acute energy intake by lipid and protein, their contribution to the latter is much less. Moreover, the effects are likely to reflect small, cumulative

    To establish normal reference values for prostate-specific antigen (PSA) in a Swedish population we investigated 878 healthy men, 56-75 years of age. They were randomly selected from a population of 9171 males in this group. Cancer of the prostate was excluded by digital rectal examination. When digital rectal examination was suspicious for carcinoma of the prostate and/or serum PSA > 4 micrograms l-1, fine-needle aspiration biopsy was performed. Central values, values of variance and reference limits were defined by a non-parametric method in four age groups. A strong positive correlation between PSA values and age was found and the variance increased with age. The relationship between PSA value and age was non-linear. For the age group 56-60 the upper reference limit (95th percentile) was 4.6 micrograms l-1 (confidence interval, CI: 3.9-5.5). For the age groups 61-65, 66-70 and 71-75 the corresponding values were 4.4 (3.8-5.2), 7.6 (6.5-8.9) and 8.4 micrograms l-1 (7.2-9.8) respectively. For the age groups studied the increment over time of the PSA value was 2-8% per year depending on age, with an average increment per year over 15 years of 4.3%. Overall, 11% of our reference sample had a serum PSA level > 4 micrograms l-1. We consider our study population to be representative for a normal Swedish male population in these age groups.

    Despite the recent studies on structural and functional adaptations of the right ventricle (RV) to exercise training, adaptations of its metabolism remain unknown. We investigated the effects of short-term, high-intensity interval training (HIIT) and moderate-intensity continuous training (MICT) on RV glucose and fat metabolism. Twenty-eight untrained, healthy 40-55 yr-old-men were randomized into HIIT (n = 14) and MICT (n = 14) groups. Subjects performed six supervised cycle ergometer training sessions within 2 wk (HIIT session: 4-6 × 30 s all-out cycling/4-min recovery; MICT session: 40-60 min at 60% peak O2 uptake). Primary outcomes were insulin-stimulated RV glucose uptake (RVGU) and fasted state RV free fatty acid uptake (RVFFAU) measured by positron emission tomography. Secondary outcomes were changes in RV structure and function, determined by cardiac magnetic resonance. RVGU decreased after training (-22% HIIT, -12% MICT, P = 0.002 for training effect), but RVFFAU was not affected by the training (P = 0.74). RV end-diastolic and end-systolic volumes, respectively, increased +5 and +7% for HIIT and +4 and +8% for MICT (P = 0.002 and 0.005 for training effects, respectively), but ejection fraction mildly decreased (-2% HIIT, -4% MICT, P = 0.034 for training effect). RV mass and stroke volume remained unaltered. None of the observed changes differed between the training groups (P > 0.12 for group × training interaction). Only 2 wk of physical training in previously sedentary subjects induce changes in RV glucose metabolism, volumes, and ejection fraction, which precede exercise-induced hypertrophy of RV.

    We have used the gene-centric Illumina HumanCVD BeadChip to identify common genetic determinants of Von Willebrand factor (vWF) levels in healthy men and women. The Whitehall II (WHII) study (n= 5592) and the British Women's Heart and Health Study (BWHHS) (n= 3445) were genotyped using the HumanCVD BeadChip. Replication was conducted in the British Regional Heart Study (n= 3897) and 1958 Birth Cohort (n= 5048). We identified 48 single nucleotide polymorphisms (SNPs) in four genes/regions associated with vWF at P < 10(-4) . These included 19 SNPs at the ABO blood group locus with the lead variant being rs657152 (P= 9.7 × 10(-233) ). The lead variant in the 24 VWF SNPs was rs1063856 (P= 2.3 × 10(-20) ). SNPs at ESR1 (rs6909023) and NRG1(rs1685103) showed modest associations with vWF, but these were not confirmed in a meta-analysis. Using variable selection, five SNPs at the locus for ABO and two for VWF were found to have independent associations with vWF levels. After adjustment for age and gender, the selected ABO SNPs explained 15% and the VWF SNPs an additional 2% of the variance in vWF levels. Individuals at opposite tails of the additive seven SNP allele score exhibited substantial differences in vWF levels. These data demonstrate that multiple common alleles with small effects make, in combination, important contributions to individual differences in vWF levels. PMID:21534939

    We tested the hypothesis that sprint interval training (SIT) causes larger improvements in glucose and free fatty acid uptake (FFAU) in lower and upper body muscles than moderate-intensity training (MIT). Twenty-eight healthy, untrained, middle-aged men were randomized into SIT (n = 14, 4-6 × 30 s of all-out cycling/4 min recovery) and MIT groups [n = 14, 40-60 min cycling at 60% of peak O2 uptake (V̇o2 peak)] and completed six training sessions within 2 wk. Pre- and postmeasurements included V̇o2 peak, whole body (M-value), muscle-specific insulin-stimulated glucose uptake (GU), and fasting FFAU measured with positron emission tomography in thigh [quadriceps femoris (QF) and hamstrings] and upper body (deltoids, biceps, and triceps brachii) muscles. V̇o2 peak and M-value improved significantly by 6 and 12% in SIT, and 3 and 8% in MIT, respectively,. GU increased significantly only in the QF, and there was no statistically significant difference between the training modes. GU increased in all four heads of QF in response to SIT, but only in the vasti muscles in response to MIT, whereas in rectus femoris the response was completely lacking. Training response in FFAU in QF was smaller and nonsignificant, but it also differed between the training modes in the rectus femoris. In conclusion, SIT and MIT increased insulin-stimulated GU only in the main working muscle QF and not in the upper body muscles. In addition, the biarticular rectus femoris did not respond to moderate-intensity training, reflecting most probably poor activation of it during moderate-intensity cycling. PMID:25767035

    Full Text Available Total sleep deprivation (TSD exerts strong modulatory effects on the secretory activity of endocrine systems that might be related to TSD-induced challenges of cerebral glucose metabolism. Here, we investigate whether TSD affects the course of male pituitary-gonadal and pituitary-thyroid axis related hormones during a subsequent 240-min hypoglycemic clamp. Ten healthy men were tested on 2 different conditions, TSD and 7-hour regular sleep. Circulating concentrations of total testosterone, prolactin (PRL, thyroid stimulating hormone (TSH, free triiodothyronine (fT3, and free thyroxin (fT4 were measured during baseline and a subsequent hypoglycemic clamp taking place in the morning. Basal, i.e. at 07:00 am measured, concentrations of total testosterone (P = 0.05 and PRL (P<0.01 were lower while the values of TSH (P = 0.02, fT3 (P = 0.08, and fT4 (P = 0.04 were higher after TSD as compared to regular sleep. During the subsequent hypoglycemic clamp (all measurements from baseline to the end of the clamp analyzed total testosterone concentrations in the regular sleep (P<0.01 but not in the TSD condition (P = 0.61 decreased, while PRL levels increased (P = 0.05 irrespectively of the experimental condition (P = 0.31. TSH concentrations decreased during hypoglycemia (P<0.01, with this decrease being more pronounced after TSD (P = 0.04. However, at the end of the hypoglycemic clamp concentrations all of the above mentioned hormones did not differ between the two sleep conditions. Our data indicate a profound influence of TSD on male pituitary-gonadal and pituitary-thyroid axis hormones characterized by reduced basal testosterone and PRL levels and increased TSH levels. However, since concentrations of these hormones measured at the end of the 240-min hypoglycemic clamp were not affected by TSD it can be speculated that the influence of TSD on the two endocrine axes is rather short lived or does not interact in an additive

    Full Text Available This study determined the effects of increasing loads of intraduodenal (ID dairy protein on plasma amino acid (AA concentrations, and their relationships with serum insulin, plasma glucagon-like peptide-1 (GLP-1 and energy intake. Sixteen healthy men had concentrations of AAs, GLP-1 and insulin measured in response to 60-min ID infusions of hydrolysed whey protein administered, in double-blinded and randomised order, at 2.1 (P2.1, 6.3 (P6.3 or 12.5 (P12.5 kJ/min (encompassing the range of nutrient emptying from the stomach, or saline control (C. Energy intake was quantified immediately afterwards. Compared with C, the concentrations of 19/20 AAs, the exception being cysteine, were increased, and this was dependent on the protein load. The relationship between AA concentrations in the infusions and the area under the curve from 0 to 60 min (AUC0–60 min of each AA profile was strong for essential AAs (R2 range, 0.61–0.67, but more variable for non-essential (0.02–0.54 and conditional (0.006–0.64 AAs. The AUC0–60 min for each AA was correlated directly with the AUC0–60 min of insulin (R2 range 0.3–0.6, GLP-1 (0.2–0.6 and energy intake (0.09–0.3 (p < 0.05, for all, with the strongest correlations being for branched-chain AAs, lysine, methionine and tyrosine. These findings indicate that ID whey protein infused at loads encompassing the normal range of gastric emptying increases plasma concentrations of 19/20 AAs in a load-dependent manner, and provide novel information on the close relationships between the essential AAs, leucine, valine, isoleucine, lysine, methionine, and the conditionally-essential AA, tyrosine, with energy intake, insulin and GLP-1.

    In this paper we use a social practice approach to explore men's experience of Football Fans in Training (FFIT), a group-based weight management programme for men that harnesses men's symbolic attachment to professional football clubs to engage them in lifestyle change. FFIT is delivered by community coaches in clubs' stadia and is gender-sensitised in relation to context, content and style of delivery. Using a 'toolkit' of concepts from the work of Bourdieu, Goffman and Durkheim we analysed data from 13 focus group discussions with participants, and fieldwork notes from programme observations to investigate the appeal and success of FFIT, and how it worked to support change. Our analysis builds on our work on the importance of shared symbolic commitment to the football club and being with 'men like me' to understand how the interaction context facilitated 'effervescent' experiences. These experiences encouraged men to make changes to their diet and physical activity, talk about them, practice performing them and implement them in their lives. Thus a social practice approach illuminated the social processes through which lifestyle change was achieved, and we argue that it can deepen and enrich both intervention design and evaluation.

    Although healthy eating might enhance long-term survival, few men with prostate cancer make diet changes to advance their well-being. Men's typically poor diets and uninterest in self-health may impede nutrition interventions and diet change. Food choice behavior is complex involving many determinants, including gender, which can shape men's health practices, diets, and prostate cancer experiences. Developing men-centered prostate cancer nutrition interventions to engage men (and where appropriate their partners) in promoting healthy diets can afford health benefits. This article presents an overview and synthesis of current knowledge about men's food practices and provides an analysis of diet and diet change behaviors for men with prostate cancer. Masculinity and gender relations theory are discussed in the context of men's food practices, and suggestions for future applications to nutrition and prostate cancer research and diet interventions are made.

    We hypothesized that an increased, incomplete fatty acid beta‐oxidation in mitochondria could be part of the metabolic events leading to insulin resistance and thereby an increased type 2 diabetes risk in low birth weight (LBW) compared with normal birth weight (NBW) individuals. Therefore, we...... measured fasting plasma levels of 45 acylcarnitine species in 18 LBW and 25 NBW men after an isocaloric control diet and a 5‐day high‐fat, high‐calorie diet. We demonstrated that LBW men had higher C2 and C4‐OH levels after the control diet compared with NBW men, indicating an increased fatty acid beta‐oxidation...... relative to the tricarboxylic acid cycle flux. Also, they had higher C6‐DC, C10‐OH/C8‐DC, and total hydroxyl‐/dicarboxyl‐acylcarnitine levels, which may suggest an increased fatty acid omega‐oxidation in the liver. Furthermore, LBW and NBW men decreased several acylcarnitine levels in response...

    Context: Sex steroid hormones potentiate whereas increased body mass index (BMI) represses GH secretion. Whether sex steroids modify the negative effect of BMI on secretagogue-induced GH secretion in men is not known. The issue is important in designing GH-stimulation regimens that are relatively insensitive to both gonadal status and adiposity.

    Background Oral tobacco (snuff) is taking a large market share in Scandinavia, especially with young users. However, long-term health effects are unknown. Small studies show association between snuff and reduced endothelial function, representing an early stage of vascular injury that often precedes manifest cardiovascular disease by several years. We therefore determined the associations between snuff and endothelial function in a large sample of healthy Norwegian men. Methods and Design In the Fitness substudy of the Nord-Trøndelag Health Study (HUNT3), endothelial function was measured by flow-mediated dilation (FMD). Aerobic fitness was measured by peak oxygen uptake (VO2peak). A cross-sectional design including 1 592 self-reported healthy men compared these observations with records of present tobacco use, standard cardiovascular risk factors, and socioeconomic status, using general linear models. Results FMD was lower in snuff users (FMD: 4.12%, 3.63, 4.61) compared to non-users (FMD: 4.52%, 4.27, 4.78) after adjustment for age (difference: -0.57%, -1.12, -0.01). After further adjustment for potential confounders, FMD still tended to be lower in snuff users than in non-users (difference: -0.53%, -1.09, 0.02). This difference was even more pronounced in the inactive snuff users (-0.83%, -1.59, -0.06) and in the low fit snuff users (-0.74%, CI -0.55, 0.079). Conclusions Oral tobacco is associated with a tendency towards reduced endothelial function, indicating vascular changes that precede cardiovascular disease. The strongest associations were found in men with low physical activity or reduced aerobic fitness. PMID:27490361

    Background and aims: In elderly Danes, reference intervals for hemoglobin (Hb) concentrations are derived from younger population groups. The aim was to examine reference intervals for Hb and cut-off limits for anemia by application of criteria for normality to a representative population of 80......-95 percentile 114-147 g/L in women (p= 20 had a lower frequency of anemia. There was no correlation between Hb and dietary or supplemental iron intake. In men, Hb was correlated to meat consumption. Conclusions: WHO decision limits for anemia should not be lowered in 80-year-old subjects. "Optimal" Hb...... concentrations with respect to survival appear to be at least 140 g/L in men and 131 g/L in women. Further research should evaluate whether not only treating anemia, but also increasing Hb by using erythropoietin and hematinics, may improve functional status and survival in the elderly....

    Full Text Available The Transdermal Delivery System (BIOLIPID B2® is a nanoemulsion that can be applied directly to the skin by a metered pump to deliver hormones into the systemic circulation. The aims of this study were to assess the efficacy of BIOLIPID B2® to deliver testosterone systemically and evaluate the short-term effects on Thyroid-Stimulating Hormone (TSH, C-reactive protein (CRP serum levels and blood pressure in middle aged men with testosterone deficiency. An open label randomized prospective study enrolled 14 Brazilian middle aged men with testosterone deficiency. The volunteers received in the forearm 50mg of transdermal BIOLIPID B2®-testosterone nanostructured formulation daily for 3 months. Confocal Raman Spectroscopy (CRS was used to determine depth and concentration of testosterone on skin layers. Clinical parameters and serum concentrations were compared between the baseline and 3 months after treatment. Serum concentrations of testosterone, CPR and TSH changed significantly (p0.05 and no changes were observed in the blood pressure. No adverse events were attributed to this transdermal hormone replacement therapy protocol. The BIOLIPID B2® nanoemulsion formulation is safe and effective in reestablishing testosterone and Thyroid-Stimulating Hormone (TSH serum levels. This transdermal protocol may serve as a strategy for hormone replacement therapy in middle aged men.

  7. Vascular and inflammatory high fat meal responses in young healthy men; a discriminative role of IL-8 observed in a randomized trial.

    Directory of Open Access Journals (Sweden)

    Diederik Esser

    Full Text Available BACKGROUND: High fat meal challenges are known to induce postprandial low-grade inflammation and endothelial dysfunction. This assumption is largely based on studies performed in older populations or in populations with a progressed disease state and an appropriate control meal is often lacking. Young healthy individuals might be more resilient to such challenges. We therefore aimed to characterize the vascular and inflammatory response after a high fat meal in young healthy individuals. METHODS: In a double-blind randomized cross-over intervention study, we used a comprehensive phenotyping approach to determine the vascular and inflammatory response after consumption of a high fat shake and after an average breakfast shake in 20 young healthy subjects. Both interventions were performed three times. RESULTS: Many features of the vascular postprandial response, such as FMD, arterial stiffness and micro-vascular skin blood flow were not different between shakes. High fat/high energy shake consumption was associated with a more pronounced increase in blood pressure, heart rate, plasma concentrations of IL-8 and PBMCs gene expression of IL-8 and CD54 (ICAM-1, whereas plasma concentrations of sVCAM1 were decreased compared to an average breakfast. CONCLUSION: Whereas no difference in postprandial response were observed on classical markers of endothelial function, we did observe differences between consumption of a HF/HE and an average breakfast meal on blood pressure and IL-8 in young healthy volunteers. IL-8 might play an important role in dealing with high fat challenges and might be an early marker for endothelial stress, a stage preceding endothelial dysfunction.

    Full Text Available The present study aimed to determine the day to day variability and reliability of several blood oxidative stress markers at rest in a healthy young cohort over a four-week period. Twelve apparently healthy resistance trained males (24.6 ± 3.0 yrs were tested over 7 visits within 4 weeks with at least 72 hrs between visits at the same time of day. Subjects rested 30 minutes prior to blood being obtained by vacutainer. Results. The highest IntraClass correlations (ICC’s were obtained for protein carbonyls (PC and oxygen radical absorbance capacity (ORAC (PC = 0.785 and ORAC = 0.780. Cronbach’s α reliability score for PC was 0.967 and for ORAC was 0.961. The ICC’s for GSH, GSSG, and the GSSG/TGH ratio ICC were 0.600, 0.573, and 0.570, respectively, with Cronbach’s α being 0.913, 0.904, and 0.903, respectively. Xanthine oxidase ICC was 0.163 and Cronbach’s α was 0.538. Conclusions. PC and ORAC demonstrated good to excellent reliability while glutathione factors had poor to excellent reliability. Xanthine oxidase showed poor reliability and high variability. These results suggest that the PC and ORAC markers were the most stable and reliable oxidative stress markers in blood and that daily changes across visits should be considered when interpreting resting blood oxidative stress markers.

    Full Text Available Abstract Background The importance of the postprandial state for the early stages of atherogenesis is increasingly acknowledged. We conducted assessment of association between postprandial triglycerides, insulin and glucose after ingestion of a standardized lipid-rich test meal, and soluble cellular adhesion molecules (sCAM in young healthy subjects. Methods Metabolic parameters and sICAM-1, sVCAM-1 and E-selectin were measured before and hourly until 6 hours after ingestion of a lipid-rich meal in 30 healthy young men with fasting triglycerides 260 mg/dl. Levels of CAM were compared in HR and NR, and correlation with postprandial triglyceride, insulin and glucose response was assessed. Results Fasting sICAM-1 and sVCAM-1 levels were significantly higher in HR as compared to NR (p = 0.046, p = 0.03. For sE-selectin there was such a trend (p = 0.05. There was a strong positive and independent correlation between sICAM-1 and postprandial insulin maxima (r = 0.70, p Conclusion This independent association of postprandial triglycerides with sICAM-1 may indicate a particular impact of postprandial lipid metabolism on endothelial reaction.

  12. Alcohol administration attenuates hypothalamic-pituitary-adrenal (HPA) activity in healthy men at low genetic risk for alcoholism, but not in high-risk subjects.

    Acute alcohol challenge studies in rodents and naturalistic observations in drinking alcoholics suggest that alcohol stimulates the hypothalamic-pituitary-adrenal (HPA) system. The literature on respective studies in healthy volunteers is more inconsistent, suggesting differential alcohol effects depending on dosage, recent drinking history, family history of alcoholism and alcohol-induced side effects. These papers and the putative pharmacologic mechanisms underlying alcohol effects on the HPA system are reviewed here and compared with a new study, in which we investigated how secretion of adrenocorticotrophin (ACTH) and cortisol is affected by ingestion of 0.6 g/kg ethanol in 33 young healthy socially drinking males with a paternal history of alcoholism (PHP) versus 30 family history negative (FHN) males. Alcohol and placebo were administered in a 2-day, double-blind, placebo controlled crossover design with randomized administration sequence. After administration of placebo, ACTH and cortisol decreased steadily over 130 minutes. In FHN subjects, secretion of both hormones was even more attenuated after alcohol, resulting in significantly lower levels compared with placebo. In PHP subjects, no alcohol effect on hormone secretion could be detected. The ratio of cortisol to ACTH secretion, each expressed as area under the secretion curve, was significantly increased by alcohol in FHN and PHP participants. These results argue against HPA stimulation being a mechanism that promotes the transition from moderate to dependent drinking. The fact that alcohol-induced HPA suppression was not detected in PHP males is consistent with the general concept that subjects at high risk for alcoholism exhibit less-pronounced alcohol effects.

The objective of this study was to examine of the effects of pea components on FI at an ad libitum meal, as well as appetite and BG responses before and after the meal. In a repeated-measures crossover trial, men (n = 15) randomly consumed (i) pea hull fibre (7 g), (ii) pea protein (10 g), (iii) pea protein (10 g) plus hull fibre (7 g), (iv) yellow peas (406 g), and (v) control. Pea hull fibre and protein were served with tomato sauce and noodles, while yellow peas were served with tomato sauce. Control was noodles and tomato sauce. FI was measured at a pizza meal (135 min). Appetite and BG were measured pre-pizza (0-135 min) and post-pizza (155-215 min). Protein plus fibre and yellow peas led to lower pre-pizza BG area under the curve compared with fibre and control.

    2005-10-01

    The present study was designed to investigate the metabolic and sympathetic responses to a high-fat meal in humans. Fourteen young men (age: 23.6 +/- 0.5 y, BMI: 21.3 +/- 0.4 kg/m2) were examined for energy expenditure and fat oxidation measured by indirect calorimetry for 3.5 h after a high-fat (70%, energy from fat) or an isoenergetic low-fat (20% energy from fat) meal served in random order. The sympathetic nervous system (SNS) activity was assessed using power spectral analysis of heart rate variability (HRV). After the high-fat meal, increases in thermoregulatory SNS activity (very low-frequency component of HRV, 0.007-0.035 Hz, 577.4+/-45.9 vs. 432.0+/-49.3 ms2, p<0.05) and fat oxidation (21.0+/-5.3 vs. 13.3+/-4.3 g, p<0.001) were greater than those after the low-fat meal. However, thermic effects of the meal (TEM) were lower after the high-fat meal than after the low-fat meal (27.5+/-11.2 vs. 36.1+/-10.9 kcal, p<0.05). In conclusion, the high-fat meal can stimulate thermoregulatory SNS and lipolysis, but resulted in lower TEM, suggesting that a high proportion of dietary fat intake, even with a normal daily range of calories, may be a potent risk factor for further weight gain.

    One hour inhalation of 0.7 ppm (1.32 mg/m3) of nitrogen dioxide (NO2), 0.7 ppm (1.4 mg/m3) of ozone (O3), and their mixture, 0.5 ppm (0.9 mg/m3) of NO2 and 0.5 ppm (1.0 mg/m3) of O3, and sham inhalation were conducted in five healthy male volunteers through mouth breathing using a multipurpose inhalation apparatus. Airway response was measured by specific airway conductance (Gaw/Vtg) and maximum expiratory flow rate at 50 and 25 percent forced vital capacity (Vmax50, Vmax25). Evaluations by analysis of variance revealed: no significant effect of inhalation of NO2 alone, slight significant transient decrease of Vmax50 in inhalation of O3 along (0.1 greater than p greater than 0.05), and slight reversible decrease of Gaw/Vtg and Vmax50 in inhalation of NO2 and O3 in combination (0.1 greater than p greater than 0.05). As their variations were within the range of normal diurnal change, these results were considered to be non-adverse effects.

    Pulses are low-glycaemic foods rich in protein (20-25 %), resistant starch and fibre that suppress appetite and glycaemia. The objective of the present study was to elucidate the component(s) of yellow peas responsible for these benefits and assess their efficacy as value-added food ingredients. We investigated the effects of 10 or 20 g of isolated yellow pea protein (P10 and P20) or fibre (F10 and F20) on food intake (FI) at an ad libitum pizza meal served at 30 min (Expt 1, n 19) or 120 min (Expt 2, n 20) and blood glucose (BG) and appetite in young, healthy males (20-30 years). In Expt 1, P20 led to lower FI than control (4937 (sem 502) v. 5632 (sem 464) kJ (1180 (sem 120) v. 1346 (sem 111) kcal)) and all other treatments (P yellow peas in the regulation of glycaemia and FI, but its second-meal effects disappear by 2 h post-consumption.

    Aerobic exercises such as running, walking and cycling are known to elicit a PEH (post-exercise hypotensive) response in both trained and UT (untrained) subjects. However, it is not known whether swim exercise produces a similar effect in normotensive individuals. The complex acute physiological responses to water immersion suggest swimming may affect BP (blood pressure) differently than other forms of aerobic exercises. We tested the hypothesis that an acute bout of swimming would fail to elicit a PEH BP response compared with an equivalent bout of stationary cycling, regardless of training state. We studied 11 UT and ten triathlon-trained young healthy normotensive [SBP/DBP (systolic BP/diastolic BP) swimming sessions to assess changes in BP during a 75-min seated recovery. CO (cardiac output), SV (stroke volume), TPR (total peripheral resistance), HR (heart rate), HRV (HR variability) and core and skin temperature were also assessed. In UT subjects, PEH was similar between cycling (-3.1±1 mmHg) and swimming (-5.8±1 mmHg), with the greater magnitude of PEH following swimming, reflecting a significant fall in SV between modalities (Pswimming (0.3±1 mmHg), yet had a significant fall in SBP at 50 min post-cycling exercise (-3.7±1 mmHg) (Pswimming in the trained group may reflect a higher cardiac sympathetic outflow [as indicated by the LF (low-frequency) spectral component of HRV) (25 and 50 min) (Pswimming.

    Physical inactivity during space flight has a profound effect on glucose metabolism. The aim of this study was to test whether endurance training (ET) may improve a negative effect of subsequent -6∘ head-down bed rest (HDBR) on glucose metabolism. Fourteen healthy males completed the study consisting of 6 weeks lasting ET followed by 6 days HDBR. Treadmill exercise at 80% of pre-training VO2max and 75 g oral glucose tolerance test (OGTT) were performed before and after ET as well as after HDBR. ET increased VO2max by 11%. ET significantly lowered while HDBR had no effect on fasting and OGTT plasma glucose levels. ET had no effect while HDBR was followed by an augmentation of insulin and C-peptide response to OGTT. Insulin sensitivity tended to increase after ET and to decrease during HDBR, however, mostly without statistical significance. Plasma glucose, insulin and C-peptide response to exercise were elevated after HDBR only. Our study shows that antecedent physical training could ameliorate a negative effect of simulated microgravity on insulin-mediated glucose metabolism.

    Observational data show an inverse association between the consumption of whole-grain foods, and inflammation and related diseases. Although the underlying mechanisms are unclear, whole grains, and in particular the aleurone layer, contain a wide range of components with putative antioxidant and anti-inflammatory effects. We evaluated the effects of a diet high in wheat aleurone on plasma antioxidants status, markers of inflammation and endothelial function. In this parallel, participant-blinded intervention, seventy-nine healthy, older, overweight participants (45-65 years, BMI>25 kg/m²) incorporated either aleurone-rich cereal products (27 g aleurone/d), or control products balanced for fibre and macronutrients, into their habitual diets for 4 weeks. Fasting blood samples were taken at baseline and on day 29. Results showed that, compared to control, consumption of aleurone-rich products provided substantial amounts of micronutrients and phytochemicals which may function as antioxidants. Additionally, incorporating these products into a habitual diet resulted in significantly lower plasma concentrations of the inflammatory marker, C-reactive protein (P = 0·035), which is an independent risk factor for CVD. However, no changes were observed in other markers of inflammation, antioxidant status or endothelial function. These results provide a possible mechanism underlying the beneficial effects of longer-term whole-grain intake. However, it is unclear whether this effect is owing to a specific component, or a combination of components in wheat aleurone.

    Full Text Available The 5-hydroxytryptamine transporter gene-linked polymorphic region (5-HTTLPR has been linked to increased stress responsiveness and negative emotional states. During fearful face recognition individuals with the s allele of 5-HTTLPR show greater amygdala activation. We aimed to test the hypothesis that the 5-HTTLPR polymorphism differentially affects connectivity within brain networks during an aversive visceral stimulus.Twenty-three healthy male subjects were enrolled. DNA was extracted from the peripheral blood. The genotype of 5-HTTLPR was determined using polymerase chain reaction. Subjects with the s/s genotype (n = 13 were compared to those with the l allele (genotypes l/s, l/l, n = 10. Controlled rectal distension from 0 to 40 mmHg was delivered in random order using a barostat. Radioactive H2[15-O] saline was injected at time of distension followed by positron emission tomography (PET. Changes in regional cerebral blood flow (rCBF were analyzed using partial least squares (PLS and structural equation modeling (SEM.During baseline, subjects with s/s genotype demonstrated a significantly increased negative influence of pregenual ACC (pACC on amygdala activity compared to l-carriers. During inflation, subjects with s/s genotype demonstrated a significantly greater positive influence of hippocampus on amygdala activity compared to l-carriers.In male Japanese subjects, individuals with s/s genotype show alterations in the connectivity of brain regions involved in stress responsiveness and emotion regulation during aversive visceral stimuli compared to those with l carriers.

    Aerobic exercises such as running, walking and cycling are known to elicit a PEH (post-exercise hypotensive) response in both trained and UT (untrained) subjects. However, it is not known whether swim exercise produces a similar effect in normotensive individuals. The complex acute physiological responses to water immersion suggest swimming may affect BP (blood pressure) differently than other forms of aerobic exercises. We tested the hypothesis that an acute bout of swimming would fail to elicit a PEH BP response compared with an equivalent bout of stationary cycling, regardless of training state. We studied 11 UT and ten triathlon-trained young healthy normotensive [SBP/DBP (systolic BP/diastolic BP) swimming sessions to assess changes in BP during a 75-min seated recovery. CO (cardiac output), SV (stroke volume), TPR (total peripheral resistance), HR (heart rate), HRV (HR variability) and core and skin temperature were also assessed. In UT subjects, PEH was similar between cycling (-3.1±1 mmHg) and swimming (-5.8±1 mmHg), with the greater magnitude of PEH following swimming, reflecting a significant fall in SV between modalities (PTrained individuals did not exhibit a PEH response following swimming (0.3±1 mmHg), yet had a significant fall in SBP at 50 min post-cycling exercise (-3.7±1 mmHg) (Pswimming in the trained group may reflect a higher cardiac sympathetic outflow [as indicated by the LF (low-frequency) spectral component of HRV) (25 and 50 min) (Ptraining may limit the potential for an effective post-exertional hypotensive response to aerobic swimming.

    The tracer {sup 123}I-2-([2-({l_brace}dimethylamino{r_brace}methyl)phenyl]thio)-5-iodophenylamine ([{sup 123}I]ADAM) has been developed to image serotonin transporters (SERTs) with SPECT. Preclinical studies have shown that [{sup 123}I]ADAM binds selectively to SERTs. Moreover, initial human studies have shown that [{sup 123}I]ADAM binding could be blocked by selective serotonin reuptake inhibitors (SSRIs). However, in humans it has not been proven that [{sup 123}I]ADAM binds selectively to SERTs. We examined the in vivo availability of SERTs in 12 healthy young volunteers 5 h after bolus injection of [{sup 123}I]ADAM. To evaluate the selectivity of binding, four participants were pretreated (double-blinded design) with placebo, four with paroxetine (20 mg) and four with the dopamine/norepinephrine blocker methylphenidate (20 mg). SPECT studies were performed on a brain-dedicated system (Neurofocus), and the SPECT images were coregistered with individual MR scans of the brain. ADAM binding in SERT-rich brain areas and cerebellar cortex (representing non-specific binding) was assessed by drawing regions of interest (ROIs) on the individual MR images. Specific to non-specific ratios were used as the outcome measure. We found that specific to non-specific ratios were statistically significantly lower in paroxetine-pretreated participants than in placebo- or methylphenidate-pretreated participants. No such difference was found between groups pretreated with placebo or methylphenidate. Our preliminary findings suggest that [{sup 123}I]ADAM binds selectively to SERTs in human brain. (orig.)

    Full Text Available Abstract Background We have previously shown the high prevalence of oral anti-human papillomavirus type 16 (HPV-16 antibodies in women with HPV-associated cervical neoplasia. It was postulated that the HPV antibodies were initiated after HPV antigenic stimulation at the cervix via the common mucosal immune system. The present study aimed to further evaluate the effectiveness of oral fluid testing for detecting the mucosal humoral response to HPV infection and to advance our limited understanding of the immune response to HPV. Methods The prevalence of oral HPV infection and oral antibodies to HPV types 16, 18 and 11 was determined in a normal, healthy population of children, adolescents and adults, both male and female, attending a dental clinic. HPV types in buccal cells were determined by DNA sequencing. Oral fluid was collected from the gingival crevice of the mouth by the OraSure method. HPV-16, HPV-18 and HPV-11 antibodies in oral fluid were detected by virus-like particle-based enzyme-linked immunosorbent assay. As a reference group 44 women with cervical neoplasia were included in the study. Results Oral HPV infection was highest in children (9/114, 7.9%, followed by adolescents (4/78, 5.1%, and lowest in normal adults (4/116, 3.5%. The predominant HPV type found was HPV-13 (7/22, 31.8% followed by HPV-32 (5/22, 22.7%. The prevalence of oral antibodies to HPV-16, HPV-18 and HPV-11 was low in children and increased substantially in adolescents and normal adults. Oral HPV-16 IgA was significantly more prevalent in women with cervical neoplasia (30/44, 68.2% than the women from the dental clinic (18/69, 26.1% P = 0.0001. Significantly more adult men than women displayed oral HPV-16 IgA (30/47 compared with 18/69, OR 5.0, 95% CI 2.09–12.1, P Conclusion The increased prevalence of oral HPV antibodies in adolescent individuals compared with children was attributed to the onset of sexual activity.

    PlanHab is a planetary habitat simulation study. The atmosphere within future space habitats is anticipated to have reduced Po2, but information is scarce as to how physiological systems may respond to combined exposure to moderate hypoxia and reduced gravity. This study investigated, using a randomized-crossover design, how insulin sensitivity, glucose tolerance, and circulating lipids were affected by 16 days of horizontal bed rest in normobaric normoxia [NBR: FiO2 = 0.209; PiO2 = 133.1 (0.3) mmHg], horizontal bed rest in normobaric hypoxia [HBR: FiO2 = 0.141 (0.004); PiO2 = 90.0 (0.4) mmHg], and confinement in normobaric hypoxia combined with daily moderate intensity exercise (HAMB). A mixed-meal tolerance test, with arterialized-venous blood sampling, was performed in 11 healthy, nonobese men (25-45 yr) before (V1) and on the morning ofday 17of each intervention (V2). Postprandial glucose and c-peptide response were increased at V2 of both bed rest interventions (PHypoxia did not alter the adverse effects of bed rest on insulin sensitivity and glucose tolerance but appeared to increase insulin clearance. The negative effect of bed rest on HDL was compounded in hypoxia, which may have implications for long-term health of those living in future space habitats. PMID:26769956

Brain α{sub 2C}-adrenoceptors may be therapeutic targets in several neuropsychiatric disorders, including depression, schizophrenia and Alzheimer's disease. To validate the use of {sup 11}C-ORM-13070 in humans, we investigated its radiometabolism, pharmacokinetics, whole-body distribution and radiation dose. Radiometabolism was studied in a test-retest setting in six healthy men. After intravenous injection of {sup 11}C-ORM-13070, blood samples were drawn over 60 min. Plasma samples were analysed by radio-HPLC for intact tracer and its radioactive metabolites. Metabolite-corrected plasma time-activity curves were used for calculation of pharmacokinetics. In a separate group of 12 healthy men, the whole-body distribution of {sup 11}C-ORM-13070 and radiation exposure were investigated by dynamic PET/CT imaging without blood sampling. Two radioactive metabolites of {sup 11}C-ORM-13070 were detected in human arterial plasma. The proportion of unchanged {sup 11}C-ORM-13070 decreased from 81 ± 4 % of total radioactivity at 4 min after tracer injection to 23 ± 4 % at 60 min. At least one of the radioactive metabolites penetrated into red blood cells, while the parent tracer remained in plasma. The apparent elimination rate constant and corresponding half-life of unchanged {sup 11}C-ORM-13070 in arterial plasma were 0.0117 ± 0.0056 min{sup -1} and 73.6 ± 35.8 min, respectively. The organs with the highest absorbed doses were the liver (12 μSv/MBq), gallbladder wall (12 μSv/MBq) and pancreas (9.1 μSv/MBq). The mean effective dose was 3.9 μSv/MBq, with a range of 3.6 - 4.2 μSv/MBq. {sup 11}C-ORM-13070 was rapidly metabolized in human subjects after intravenous injection. The effective radiation dose of {sup 11}C-ORM-13070 was in the same range

    Reflecting diversifying shift systems, extensive effort is put into managing shiftwork and reducing safety and health risks. It is accepted that shiftworkers are exposed to particular risks inherent in their irregular work schedules. This raises the question of how and to what extent we can ensure healthy work life for shiftworkers. In answering the question, we need to identify effective measures to improve both shiftworking conditions and the health of shiftworkers. Based on recent experiences in managing shiftwork, we note three directions of such measures: (a) comprehensive action to avoid risk-enhancing conditions based on general guidelines, (b) risk control as to workload, worksite ergonomics and risk reduction, and (c) support for flexible and restful working life. International standards are obviously relevant to these three aspects. Our own experiences in applying a set of ergonomic checkpoints to plant maintenance shiftwork demonstrate the usefulness of focusing on flexible work schedules and on multiple job-related factors such as night workload, ergonomic environment, resting conditions and training. There is a strong need for participatory planning and implementation of multi-area improvements as well as for relying on flexible schedules and autonomic teamwork. We may conclude that healthy shiftwork and healthy shiftworkers are compatible with each other only when certain conditions are met. In achieving this end, we need to combine (a) comprehensive measures to improve work schedules and job life, (b) strict risk management and (c) locally adjusted participatory steps for continual improvement.

    Men are more likely to die of cancer, heart disease, or diabetes at younger ages than women - a reality that is compounded by the reluctance of men to use healthcare services. In addition to reduced life expectancy, men can also expect to live fewer healthy years than their female counterparts. As gynecologists and obstetricians have led the women's health movement in addressing gender-specific gaps in care, urologists are well-poised to take on a leadership role to advocate for, and address, men's health initiatives.

The present study was from a larger study that investigates the church's role as a social marketer of CRC risk and prevention messages, and whether religiously targeted and tailored health promotion materials will influence screening outcome. We used an integrated theoretical approach to explore participants' perceptions of CRC risk and prevention and how promotion messages should be developed and socially marketed by the church. Six focus groups were conducted with men from predominately AA churches in the Midwest. Themes from focus group discussions showed participants lacked knowledge about CRC, feared cancer diagnosis, and feared the procedure for screening. Roles of masculinity and the mistrust of physicians were also emergent themes. Participants did perceive the church as a trusted marketer of CRC but believed that promotional materials should be cosponsored and codeveloped by reputable health organizations. Employing the church as a social marketer of CRC screening promotion materials may be useful in guiding health promotions and addressing barriers that are distinct among African American men.

    Alzheimer’s disease is a neurodegenerative disorder characterized by progressive cognitive impairment and neuropathology. Recent preclinical and epidemiological studies proposed statins as a possible therapeutic drug for Alzheimer’s disease, but the exact mechanisms of action are stil unknown. Biliverdin reductase-A is a pleiotropic enzyme involved in cel ular stress responses. It not only transforms biliverdin-IX alpha into the antioxidant bilirubin-IX alpha but its serine/threonine/tyrosine kinase activity is able to modulate cel signaling networks. We previously reported the beneficial effects of atorvastatin treatment on biliverdin reductase-A and heme oxygenase-1 in the brains of a well characterized pre-clinical model of Alzheimer’s disease, aged beagles, together with observed improvement in cognition. Here we extend our knowledge of the effects of atorvastatin on inducible nitric oxide synthase in parietal cortex, cerebel um and liver of the same animals. We demonstrated that atorvastatin treatment (80 mg/day for 14.5 months) to aged beagles selectively increased inducible nitric oxide synthase in the parietal cortex but not in the cerebel um. In contrast, inducible nitric oxide synthase protein levels were significantly decreased in the liver. Significant positive correlations were found between biliverdin reductase-A and inducible nitric oxide synthase as wel as heme oxygenase-1 protein levels in the parietal cortex. The opposite was observed in the liver. Inducible nitric oxide synthase up-regulation in the parietal cortex was positively associated with improved biliverdin reductase-A functions, whereas the oxidative-induced impairment of biliverdin reductase-A in the liver negatively affected inducible nitric oxide synthase expression, thus suggesting a role for biliverdin reductase-A in atorvastatin-dependent inducible nitric oxide synthase changes. Interestingly, increased inducible nitric oxide synthase levels in the parietal cortex were not associated with higher oxidative/nitrosative stress levels. We hypothesize that biliverdin reductase-A-dependent inducible nitric oxide synthase regulation strongly contributes to the cognitive improvement observed fol owing atorvastatin treatment.

    Many studies show that men make specific lifestyle choices. However, regarding high blood pressure (HBP), guidelines are without distinction for gender. The purpose of this project is to explore the men's experience with HBP. Using a phenomenological design, semi-structured interviews were conducted with ten men living with HBP to explore beliefs and perceptions of men living with HBP. The main framework used is the health belief model. Two themes emerged: the meaning given to HBP (an unavoidable disease, the trivialization of HBP et HBP as synonymous of stress) and the management of this illness (the notion of control, the paradox of knowing about what to do and implementation of healthy lifestyle, relationship with health professionals). These results bring a better understanding of the experience of men with hypertension. PMID:26333268

In this article attention is paid to the critical loads method, the related data and the European network. [Dutch] Kennis van duurzame depositieniveaus (critical loads) voor verzuring, vermesting en van zware metalen helpt bij de bepaling van bovengrenzen aan emissies. Dit is belangrijk voor de bescherming van Europese natuurgebieden en van de menselijke gezondheid. Critical loads worden berekend in ongeveer 1,3 miljoen vegetatie-bodem combinaties in Europa door een netwerk van 27 National Focal Centres in EC-lidstaten en Partijen onder de LRTAP Conventie (Convention on Long-range Transboundary Air Pollution). De spreiding en niveaus van critical loads worden bepaald door de aard van de beschouwde natuurlijke systemen, terwijl deposities afhankelijk zijn van landenemissies en menselijk handelen. De vergelijking van deposities met critical loads legt het verband tussen landenemissies en risico's voor natuur en mens. Om in het Europese luchtbeleid kosten en geografisch effectieve emissiereducties te helpen bepalen is kennis van robuuste critical loads dan ook zeer belangrijk. Hoe komen ze tot stand en welke rol spelen ze binnen de conventie? Hoe staat het met vermesting over vijftien jaar? En hoe verhoudt dit zich dat tot het broeikaseffect?.

    Appropriate rehydration and nutrient intake in recovery is a key component of exercise performance. This study investigated whether the recovery of body net fluid balance (NFB) following exercise and thermal dehydration to -2 % of body mass (BM) was enhanced by a metered rate of ingestion of milk (M) compared with a carbohydrate-electrolyte solution (CE) or water (W). In randomised order, seven active men (aged 26·2 (sd 6·1) years) undertook exercise and thermal dehydration to -2 % of BM on three occasions. A metered replacement volume of M, CE or W equivalent to 150 % of the BM loss was then consumed within 2-3 h. NFB was subsequently measured for 5 h from commencement of rehydration. A higher overall NFB in M than CE (P=0·001) and W (P=0·006) was observed, with no difference between CE and W (P=0·69). After 5 h, NFB in M remained positive (+117 (sd 122) ml) compared with basal, and it was greater than W (-539 (sd 390) ml, P=0·011) but not CE (-381 (sd 460) ml, P=0·077, d=1·6). Plasma osmolality (Posm) and K remained elevated above basal in M compared with CE and W. The change in Posm was associated with circulating pre-provasopressin (r s 0·348, Pdehydration.

    A high consumption of trans fatty acids (TFAs) is associated with an increased risk of cardiovascular diseases (CVDs). High-density lipoproteins (HDLs) have many cardioprotective properties and transport functional microRNAs (miRNAs) to recipient cells. We hypothesized that dietary TFAs modify the HDL-carried miRNA profile, therefore modulating its cardioprotective properties. We assessed whether consumption of dietary TFAs modifies HDL-carried miR-223-3p and miR-135a-3p concentration and the inter-relationship between diet-induced changes in HDL-carried miRNA concentration and CVD risk markers. In a double blind, randomized, crossover, controlled study, 9 men were fed each of 3 experimental isoenergetic diets: 1) High in industrial TFA (iTFA; 3.7% energy); 2) High in TFA from ruminants (rTFA; 3.7% energy); 3) Low in TFA (control; 0.8% energy) for 4 weeks each. HDLs were isolated by ultracentrifugation and miRNAs were quantified by RT-qPCR. Variations in HDL-miR-223-3p concentration were negatively correlated with variations in HDL-cholesterol after the iTFA diet (rs = 0.82; P = 0.007), and positively correlated with variations in C-reactive protein concentration after the rTFA diet (rs = 0.75; P = 0.020). Variations in HDL-miR-135a-3p concentration were positively correlated with variations in total triglyceride (TG) concentration following the iTFA diet (rs = -0.82; P = 0.007), and with variations in low-density lipoprotein (LDL)-TG concentration following the rTFA diet (rs = 0.83; P = 0.005), compared to the control diet. However, the consumption of dietary TFAs has no significant unidirectional impact on HDL-carried miR-223-3p and miR-135a-3p concentrations. Our results suggest that the variability in the HDL-carried miRNAs response to TFA intake, by being associated with variations in CVD risk factors, might reflect physiological changes in HDL functions.

    Growing evidence suggests that testosterone may play a role in the pathophysiology of schizophrenia given that testosterone has been linked to cognition and negative symptoms in schizophrenia. Here, we determine the extent to which serum testosterone levels are related to neural activity in affective processing circuitry in men with schizophrenia. Functional magnetic resonance imaging was used to measure blood-oxygen-level-dependent signal changes as 32 healthy controls and 26 people with schizophrenia performed a facial emotion identification task. Whole brain analyses were performed to determine regions of differential activity between groups during processing of angry versus non-threatening faces. A follow-up ROI analysis using a regression model in a subset of 16 healthy men and 16 men with schizophrenia was used to determine the extent to which serum testosterone levels were related to neural activity. Healthy controls displayed significantly greater activation than people with schizophrenia in the left inferior frontal gyrus (IFG). There was no significant difference in circulating testosterone levels between healthy men and men with schizophrenia. Regression analyses between activation in the IFG and circulating testosterone levels revealed a significant positive correlation in men with schizophrenia (r=.63, p=.01) and no significant relationship in healthy men. This study provides the first evidence that circulating serum testosterone levels are related to IFG activation during emotion face processing in men with schizophrenia but not in healthy men, which suggests that testosterone levels modulate neural processes relevant to facial emotion processing that may interfere with social functioning in men with schizophrenia.

    Full Text Available Background. An important problem is to investigate the frequency of aneuploidy in sperms of infertile men according to their changes in karyotype, that would allow to understand the contribution of paternal factor in the formation of chromosomal aberrations of embryos. Objective. To study the frequency of aneuploidy in spermatozoa from infertile men with normal karyotype and chromosomal changes. Methods. Fluorescence in situ hybridization (FISH of spermatozoa (chromosomes 13, 16, 18, 21, 22, X and Y was performed in 79 infertile men with normal karyotype, in 16 with chromosomal abnormalities, in 18 with chromosomal polymorphism and in 29 healthy men. In total 23,867 of sperm cores were analyzed. Results. In men with infertility an aneuploid sperms were in 5.7 times more often than in fertile patients (P˂0,01. An aneuploidy of sperms in infertile men with a chromosomal abnormality were in 2.1 times, with a chromosomal polymorphism in 1.4 times more often than in infertile patients with a normal karyotype (P˂0,05. In all patients the most common aneuploidies were in chromosomes XY, 21 and 22. The study of aneuploidy frequency in spermatozoa at different variants of chromosomal pathology showed that in men with paracentric inversions rate was 5.75 - 7.65%, whereas in patients with quantitative and other structural chromosomal abnormalities it was above 11.73 - 17.82%. Conclusion. The frequency of chromosomal aberrations in spermatozoa is highest in men with genomic and chromosomal mutations. In infertile patients with changes in the karyotype the gametes with mutations de novo can be produced. Citation: Grabar VV, Feskov AM, Stefanovich AV, Zhilkova ES.

    The objective was to use thermal imaging (ThermaCAM SC500) as an effective tool in establishing a thermal map of young participants, with a high diagnostic value for medicine, physiotherapy and sport. A further aim was to establish temperature distributions and ranges on the body surface of the young women and men as standard temperatures for the examined age group, taking into account BMI, body surface area and selected parameters of body fat distribution. The participants included young, healthy and physically active women (n = 100) and men (n = 100). In the women and men, the highest Tmean temperatures were found on the trunk. The warmest were the chest and upper back, then the lower back and abdomen. The lowest Tmean were found in the distal parts of the body, especially on the lower limbs. The results showed that only in the area of the chest was Tmean significantly higher in women than in men. In the areas of the hands (front and back) Tmean were similar for women and men. In the other analyzed body surface areas, Tmean were significantly lower in women. Research showed significant differences in body surface temperature between the women and men. Among the analyzed characteristics, Tmean in the chest, upper back, abdomen, lower back (both in women and men) were mainly correlated with BMI and PBF; the correlations were negative. Difficulties in interpreting changes in temperature in selected body areas in people with various conditions can be associated with the lack of studies on large and representative populations of healthy individuals with normal weight/height parameters. Therefore, it seems that this presented research is a significant practical and cognitive contribution to knowledge on thermoregulation, and may therefore be used as a reference for other studies using thermal imaging in the evaluation of changes in body surface temperatures.

    In preparation for an intervention study in three rural Iowa restaurants, 250 customers were surveyed regarding their interest in dietary change, perceptions of the restaurant, and interest in healthy options. Customers were ages 18 to 88, with a mean age of 52, and 53% were women. Most agreed that the restaurant offers healthy meals. Options customers stated they were most likely to order if available included meat that is baked or broiled, whole-wheat bread, fresh fruit or steamed vegetables, and regular salad dressing on the side. They were least interested in low-fat sour cream, low-fat salad dressing, low-fat milk, low-calorie dessert, and holding high-fat ingredients. Women were more likely to indicate interest in healthy options than were men. Interest in several options was also positively associated with age. Increasing the healthy options in restaurants may be especially effective in changing the dietary intake of women and older adults. PMID:19515859

  19. HPV Infection in Men

    Directory of Open Access Journals (Sweden)

    2007-01-01

    Full Text Available While much is known about the natural history of cervical human papillomavirus (HPV infection and its consequences, including cervical intraepithelial neoplasia and cervical cancer, relatively little is known about the natural history of anogenital HPV infection and diseases in men. In part this reflects difficulties in penile sampling and visual assessment of penile lesions. Anal HPV infection and disease also remain poorly understood. Although HPV is transmitted sexually and infects the genitals of both sexes, the cervix remains biologically more vulnerable to malignant transformation than does the penis or anus in men. An understanding of male HPV infection is therefore important in terms of reducing transmission of HPV to women and improving women's health. However, it is also important due to the burden of disease in men, who may develop both penile and anal cancer, particularly among HIV-positive men who have sex with men. Improved sampling techniques of the male genitalia and cohort studies in progress should provide important information on the natural history of anogenital HPV infection and disease in men, including risk factors for HPV acquisition and transmission. The impact of HPV vaccination in women on male anogenital HPV infection will also need to be assessed.

    Aim: To examine the inter-relationships among age, lifestyle factors, anthropometric parameters, percent body fat and steroid hormone parameters in 531 healthy Singaporean Chinese men aged between 29 and 72 years old. Methods:Various lifestyle parameters were quantified through a survey, and testosterone (T), estradiol (E2), dehydroepiandrosterone sulphate (DHEAS) and sex hormone binding globulin (SHBG) were measured using established methods.Anthropometric parameters were collected and computed, and percent body fat (Siri) was measured using the DEXA scanner. Results: SHBG, DHEAS, bioavailable-T (Bio-T), E2, Siri, Ht, W/H, W/Ht and work stress were independently correlated with age. Using multivariate analyses and adjusting for age and other related factors, exercise,smoking and alcohol consumption have positive impacts on androgen levels and body composition. However, black and green tea consumption was associated with negative effects on body composition and with higher levels of E2 and Free Estradiol Index (FEI). Men with shorter sleep duration had significantly lower T levels as compared to those with 6 h or more of nightly sleep. Higher T levels were associated with lower levels of adiposity and other indices of adiposity, whereas higher E2 levels were related to higher levels of adiposity. Men with higher DHEAS were significantly taller and heavier than those with low DHEAS levels. Conclusion: The study showed the close interactions among the gonadal/adrenal and metabolic compartments, with age being a key determinant in their interactions.Lifestyle factors such as exercise, smoking, sleeping and alcohol and tea consumption might play significantly roles in determining the status of health in men.

    Textual and visual representations of age are instructive as they suggest ideals towards which individuals should strive and influence how we perceive age. The purpose of our study was to investigate textual and visual representations of later life in the advertisements and interest stories of six widely read North American male-oriented magazines (namely, Esquire, GQ, Maxim, Men's Health, Men's Journal, and Zoomer). Through a content analysis and a visual textual analysis, we examined how older men were depicted in the magazine images and accompanying texts. Our findings revealed that older men were largely absent, and when portrayed, were positively depicted as experienced and powerful celebrities or as healthy and happy unknown individuals. The magazine advertisements and interest stories collectively required individuals to engage in consumer culture in order to achieve age and masculinity ideals and stave off the transition from the Third Age to the Fourth Age. We consider our findings in relation to theorizing about ageism, age relations, the Third and Fourth Ages, and idealized aging masculinity.

  7. Aging men-Challenges ahead

    Institute of Scientific and Technical Information of China (English)

    Bruno Lunenfeld

    2001-01-01

    The prolongation of life expectancy and the drastic reduction of fertility rate are the primary cause of an aging world. It is projected that the elderly (above 65) will increase within the next 25 years by 82 %, whereas the new born only by 3 %. Despite the enormous medical progress during the past few decades, the last years of life are still accompanied by increasing ill health and disability. The ability to maintain active and independent living for as long as possible is a crucial factor for aging in health and dignity. Therefore, the promotion of healthy aging and the prevention of disability in men, must assume a central role in medical research and medical practice as well as in the formulation of national health and social policies. Effective programs promoting health and aging will ensure a more efficient use of health and social services and improve the quality of life in older persons by enabling them to remain independent and productive. The most important and drastic gender differences in aging are related to organs and or systems dependant or influenced by reproductive hormones. In distinction to the course of reproductive aging in women, with the rapid decline in sex hormones and expressed by the cessation of menses, aging men experience a slow and continuous decline of hormones. This decline in endocrine function involves: A decrease of testosterone, dehydroepiandrosterone (DHEA),oestrogens, thyroid stimulating hormone (TSH), growth hormone (GH), insulin-like growth factor-1 (IGF-1), and melatonin. This decrease is concomitant with an increase of LH and FSH. In addition sex hormone binding globulin's (SHBG) increase with age resulting in further lowering the concentrations of free biologically active androgens. Interventions such as hormone replacement therapy may prevent, delay or alleviate the debilitating conditions which may result from secondary partial endocrine deficiency. Primary and secondary preventive strategies such as the promotion of

    2013-02-05

    The Bellagio Report on Healthy Agriculture, Healthy Nutrition, Healthy People is the result of the meeting held at the Rockefeller Foundation Bellagio Center in Lake Como, Italy, 29 October-2 November 2012. The meeting was science-based but policy-oriented. The role and amount of healthy and unhealthy fats, with attention to the relative content of omega-3 and omega-6 fatty acids, sugar, and particularly fructose in foods that may underlie the epidemics of non-communicable diseases (NCD's) worldwide were extensively discussed.

  18. The healthy immigrant effect and mortality rates.

    According to the 2006 Census, almost the Canadian population were foreign-born, a percentage that is projected to reach at least 25% by 2031. Studies based on age-standardized mortality rates (ASMR) have found a healthy immigrant effect, with lower overall rates among immigrants. A duration effect has also been observed-immigrants' mortality advantage lessened as their time in Canada increased. ASMRs based on the 1991 to 2001 census mortality follow-up study indicate a healthy immigrant effect and a duration effect at the national level for all-cause mortality for both sexes. However, at the national level, the mortality rate among women from the United States and from Sub-Saharan Africa was similar to that of Canadian-born women. For the three largest Census Metropolitan Areas (Toronto, Montreal and Vancouver), a healthy immigrant effect was not observed among women or among most men from the United States or Sub-Saharan Africa.

    Diminished exercise capacity is a fundamental symptom of heart failure (HF), which is particularly disadvantageous for men for whom exercise capacity contributes significantly to their gender identity, self-esteem, and quality of life. In this study, we aimed to examine whether psychological gender would be different in men with systolic HF as compared with their healthy peers. The authors examined 48 men with systolic HF (age = 64 ± 10 years; body mass index = 28.3 ± 3.4 kg/m(2); NYHA I/II/III [%] = 25/65/10; left ventricular ejection fraction [LVEF] = 32.1 ± 7.8%) and 15 age-matched healthy men. Based on the results of the Polish version of the Bem Sex Role Inventory, the examined men were divided into four types of psychological gender: "masculine" (M), "feminine" (F), "unspecified" (U), and "androgynous" (A). None of the men with HF presented M type of psychological gender, whereas this type was found in 27% of the healthy men (p = .0002). The prevalence of both A (38% vs. 47%) and F (10% vs. 20%, both p > .05) types of psychological gender was similar between men with HF versus without HF. More men with HF fulfilled the criteria of the U type of psychological gender as compared with healthy peers (51% vs. 7%, p = .002). Men with HF and the F type of psychological gender were treated with spironolactone more frequently than those classified with the U and A types (both p < .05). The lack of "psychologically masculine" and the overrepresentation of "psychologically unspecified" gender types in the HF group suggests that psychological gender may be affected among men with HF.

  6. Men making sense of their chest pain--niggles, doubts and denials.

    Participant observation was undertaken of the early admission period of 25 men admitted to hospital with acute chest pain, followed by in-depth interviews of 10 of the men after discharge. Grounded theory methods were used in the analysis to develop a model of how the men came to interpret their experiences. An emerging feature of the men's experiences was that, although they had suffered intense pain prior to admission, there had been a series of delays whilst they tried to rationalize their symptoms. We relate our discussion to literature on men and masculinity and the notion of Foucault (1975) of self-surveillance, to offer an insight into the men's self concept and social situation. Our conclusions suggest that men's self concept as 'healthy' may inhibit a speedy response to the signs and symptoms of acute coronary occlusion, increasing the risk of cardiac arrest without nearby life support.

    Full Text Available In October 2010, the World Council on Genetics, Nutrition and Fitness for Health promoted a scientific meeting in Ancient Olympia, Greece, on the theme Healthy Agriculture, Healthy Nutrition, Healthy People. The meeting focused on evolutionary aspects of human diet through the life cycle in terms of genetic predisposition, overall health, prevention of disease and of unhealthy behaviors, such as poor physical activity, and dietary changes caused by the introduction of modern agriculture, from the Agribusiness to systems of food production, from climate changes to the needs imposed by urban agriculture and architecture. Nutritional medical (mostly cardiological and political aspects of disease prevention through healthy dietary habits and physical activity have always been seen in isolation. The meeting, the first of its kind, treated such aspects together, recognizing the importance of integrating and initiating a dialogue between these disciplines. The meeting gathered together experts in cardiovascular prevention, nutrition, as well as politicians, for a global discussion of these themes. A summary statement was then compiled, focusing on the main themes on which a consensus had been reached. I strongly believe that such themes have great relevance for public health, raising the need for disseminating them as widely as possible. I am thankful to the Editor of the Italian Journal of Medicine for allowing this summary document to be made available for the first time in Italy.Raffaele De Caterina

  8. Men at sport: gay men's experiences in the sport workplace.

    Science.gov (United States)

    Cavalier, Elizabeth S

    2011-01-01

    Research on sexual identity and sport has revealed a shifting narrative about the experiences of gay men. While some suggest the atmosphere is hostile, others posit that homophobia and sexual prejudice are playing less of a role in gay men's experiences. This research focuses on the experiences of 10 gay men working in professional, collegiate, and club sport, as part of a larger dataset of 37 male and female employees. Five of the men were overtly and publicly out at work, while five were closeted (to varying degrees). This article focuses on three themes for gay men working in sport: 1) the importance of coming out in the workplace; 2) the role of the locker room as a contested terrain, and 3) the disconnect between their experiences at work and their perceptions of the workplace environment as negative or positive. Men in this study were basing their impressions on their total experience in sport (as current and former players, as employees, and as fans). It also suggests that the public "story" of gay men working in sport represents one of two extremes-either the proverbial "horror story," or the extremely positive representation of gay men's experiences. This research suggests that gay men's experiences in sport are more complex and nuanced than the public narrative implies. PMID:21534074

    Humans are virtually identical in their genetic makeup, yet the small differences in our DNA give rise to tremendous phenotypic diversity across the human population. By contrast, the metagenome of the human microbiome-the total DNA content of microbes inhabiting our bodies-is quite a bit more variable, with only a third of its constituent genes found in a majority of healthy individuals. Understanding this variability in the "healthy microbiome" has thus been a major challenge in microbiome research, dating back at least to the 1960s, continuing through the Human Microbiome Project and beyond. Cataloguing the necessary and sufficient sets of microbiome features that support health, and the normal ranges of these features in healthy populations, is an essential first step to identifying and correcting microbial configurations that are implicated in disease. Toward this goal, several population-scale studies have documented the ranges and diversity of both taxonomic compositions and functional potentials normally observed in the microbiomes of healthy populations, along with possible driving factors such as geography, diet, and lifestyle. Here, we review several definitions of a 'healthy microbiome' that have emerged, the current understanding of the ranges of healthy microbial diversity, and gaps such as the characterization of molecular function and the development of ecological therapies to be addressed in the future.

    There is little research involving the US male population regarding weight control and behavior that may affect weight status. Gender-specific weight-control programs for men aren't the standard. Our study objectives were to survey dieting and health habits of an adult male employee population and to determine if the population would be interested in gender-specific programming. Demographics, weight-control practices and interest in gender-specific weight-control programs were examined cross sectionally. A 50-question web-based survey was posted via email from October 2-30, 2014 to male employees at a Mid-Atlantic university. Statistical analyses included frequencies, means and percentages. Chi square and t tests were conducted. The 254 participants were ages 18-65+ years, predominantly white, college educated with annual incomes above $50,000. Sources of nutrition knowledge ranged from a high of web sites (65 %) to a low of registered dietitians (9 %). Macronutrient restrictions reported for dieting were carbohydrates 77 %, fats 40 % and protein 19 %. The >30 age group was more likely to have: decreased amount of food intake P = .001), reducing overall calories (P = .047), skipping meals (P = .006) or trying commercial programs (P = .011). There was nothing of significance for those motivation for males to lose and maintain weight loss. PMID:26758439

  8. Men, masculine identities and childbirth.

    Dolan, Alan; Coe, Christine

    2011-11-01

    In recent years, fathers' experiences during childbirth have attracted much research and policy interest. However, little of this work has been grounded in the first-hand accounts of men and there is a lack of theory-based research to help understand men's thoughts and practices around childbirth. This paper is based on qualitative research undertaken with first-time fathers and healthcare professionals. It draws on Connell's (1995) conceptualisation of hegemonic masculinity to explore how men construct masculine identities within the context of pregnancy and childbirth and also how healthcare professionals construct masculinity. The paper demonstrates the ways in which men can find themselves marginalised within the context of pregnancy and childbirth, but are still able to draw on identifiable markers of masculine practice which enable them to enact a masculine form congruent with dominant masculinity. It also illustrates how healthcare professionals' constructions of masculinity enable them to predict how men will behave and allow them to position men in ways that involve minimum disruption to their own practice. The paper also highlights how men's marginal status is embedded in the dynamics of the social structure, which produce and reproduce dominant masculine identities within the context of childbirth.

    African American men report poorer health than do White men and have significantly greater odds for developing chronic diseases partly because of limited physical activity. Understanding how to encourage healthy behaviors among African American men will be critical in the development of effective physical activity messages and programs. Guided by principles of cultural sensitivity and social marketing, this research examined middle-aged and older African American men's recommended strategies for promoting physical activity to African American men of their age. The authors report results from 49 interviews conducted with middle-aged (45-64 years) and older (65-84 years) African American men in South Carolina. Four groups of African American men were recruited: middle-aged active men (n = 17), middle-aged inactive men (n = 12), older active men (n = 10), older inactive men (n = 10). Themes related to marketing and recruitment strategies, message content, and spokesperson characteristics emerged and differed by age and physical activity level. Recommended marketing strategies included word of mouth; use of mass media; partnering with churches, businesses, and fraternities; strategic placement of messages; culturally appropriate message framing; and careful attention to selection of program spokespersons. Findings will help in the marketing, design, implementation, and evaluation of culturally appropriate interventions to encourage physical activity among middle-aged and older African American men in the South.

  4. Regurgitation in healthy and non healthy infants

    Directory of Open Access Journals (Sweden)

    Cavallo Luciano

    2009-12-01

    Full Text Available Abstract Uncomplicate regurgitation in otherwise healthy infants is not a disease. It consists of milk flow from mouth during or after feeding. Common causes include overfeeding, air swallowed during feeding, crying or coughing; physical exam is normal and weight gain is adequate. History and physical exam are diagnostic, and conservative therapy is recommended. Pathologic gastroesophageal reflux or gastroesophageal reflux disease refers to infants with regurgitation and vomiting associated with poor weight gain, respiratory symptoms, esophagitis. Reflux episodes occur most often during transient relaxations of the lower esophageal sphincter unaccompanied by swallowing, which permit gastric content to flow into the esophagus. A minor proportion of reflux episodes occurs when the lower esophageal sphincter fails to increase pressure during a sudden increase in intraabdominal pressure or when lower esophageal sphincter resting pressure is chronically reduced. Alterations in several protective mechanisms allow physiologic reflux to become gastroesophageal reflux disease; diagnostic approach is both clinical and instrumental: radiological series are useful to exclude anatomic abnormalities; pH-testing evaluates the quantity, frequency and duration of the acid reflux episodes; endoscopy and biopsy are performed in the case of esophagitis. Therapy with H2 receptor antagonists and proton pump inhibitors are suggested.

  6. Aging Men and Prostate Cancer

    Directory of Open Access Journals (Sweden)

    Thompson B

    2015-01-01

    Full Text Available Prostate cancer (PCa is one of the most commonly diagnosed cancers in men worldwide and its incidence increases with age, mainly affecting elderly men aged 60 and above. Factors known to be associated with the development and progression of PCa are age, family history, and race/ethnicity, with age being the most important factor. The reasons for the increased incidence and mortality due to prostate cancer in elderly men are not entirely clear. Continued exposure to environmental and dietary factors may lead to accumulation of genetic and epigenetic changes over the life-span, leading to altered expression and/or activity of tumor promoter and tumor suppressor genes. Changing levels of endogenous hormones (like androgens and metabolism in elderly men may also play a role in the development of prostate cancers which may be further influenced by testosterone replacement therapy. For many decades now preventative strategies and treatments such as radiation therapy or hormone therapy, and others have been administered to manage PCa; however current studies and evidence suggest that PCa is undertreated in elderly men, despite evidence of efficacy of these treatments, which leads to higher prevalence of mortality in this age group. Studies involving basic research, preventative and management strategies are still underway to understand the mechanisms of PCa development in elderly men and treatment of this disease in ageing male population.

    The Centers for Disease Control and Prevention and Healthy People 2020 call for improvements in meeting men's reproductive health needs but little is known about the proportion of men in need. This study describes men aged 35 to 39 in need of family planning and preconception care, demographic correlates of these needs, and contraception use among men in need of family planning. Using data from Wave 4 (2008-2010) of the National Survey of Adolescent Males, men were classified in need of family planning and preconception care if they reported sex with a female in the last year and believed that they and their partner were fecund; the former included men who were neither intentionally pregnant nor intending future children and the latter included men intending future children. Men were classified as being in need of both if they reported multiple sex partners in the past year. About 40% of men aged 35 to 39 were in need of family planning and about 33% in need of preconception care with 12% in need of both. Current partner's age, current union type, and sexually transmitted infection health risk differentiated men in need of family planning and preconception care (all ps planning reported none of the time current partner hormonal use (55%) or condom use (52%) during the past year. This study identified that many men in their mid-30s are in need of family planning or preconception care.

    Characterizing the morphology of the carpometacarpal (CMC) joint bones and how they vary across the population is important for understanding the functional anatomy and pathology of the thumb. The purpose of this paper was to develop a statistical shape model of the trapezium and first metacarpal bones to characterize the size and shape of the whole bones across a cohort of 50. We used this shape model to investigate the effects of sex and age on the size and shape of the CMC joint bones and the articulating surface area of the CMC joint. We hypothesized that women have similar shape trapezium and first metacarpal bones compared to men, following scaling for overall size. We also hypothesized that age would be a significant predictor variable for CMC joint bone changes. CT image data and segmented point clouds of 50 CMC bones from healthy adult men and women were obtained from an ongoing study and used to generate two statistical shape models. Statistical analysis of the principal component weights of both models was performed to investigate morphological sex and age differences. We observed sex differences, but were unable to detect any age differences. Between men and women the only difference in morphology of the trapezia and first metacarpal bones was size. These findings confirm our first hypothesis, and suggest that the women have similarly shaped trapezium and first metacarpal bones compared to men. Furthermore, our results reject our second hypothesis, indicating that age is a poor predictor of CMC joint morphology.

    The temporal discrimination threshold (TDT) is the shortest interstimulus interval at which a subject can perceive successive stimuli as separate. To investigate the effects of aging on TDT, we studied tactile TDT using the method of limits with 120% of sensory threshold in each hand for each of 100 healthy volunteers, equally divided among men and women, across 10 age groups, from 18 to 79 years. Linear regression analysis showed that age was significantly related to left-hand mean, right-hand mean, and mean of 2 hands with R-square equal to 0.08, 0.164, and 0.132, respectively. Reliability analysis indicated that the 3 measures had fair-to-good reliability (intraclass correlation coefficient: 0.4-0.8). We conclude that TDT is affected by age and has fair-to-good reproducibility using our technique. PMID:27255827

    Full Text Available Androgenetic alopecia is hair thinning due to the stimulation of hair follicles to androgens. Incidence in men is higher than in women, it is because men have a degree higher 5? reductase. This condition can cause both physical and psychological effects to the patient. Physical effects due to baldness cause hair loss as a function of protection against heat, cold and trauma. While psychologically can affect self-esteem and self-perception of the patient. Androgenetic alopecia in men influenced by the androgen dihydrotestosterone and genetic predisposition, although the physiology remains unclear. Modality in the management of androgenetic alopecia in males patients including pharmacotherapy, hair transplants and cosmetic approach. According to the Food and Drug Administration (FDA, there are two main drugs are safe and effective in the long term given to men with androgenetic alopecia are minoxidil and finasteride. Although the mechanism of action and route of administration are different, but both drugs have similar effectiveness in stopping the progression of androgenetic alopecia in men.

    Psychosocial stress influences cognitive abilities, such as long-term memory retrieval. However, less is known about the effects of stress on cognitive flexibility, which is mediated by different neurobiological circuits and could thus be regulated by different neuroendocrine pathways. In this study, we randomly assigned healthy adults to an acute stress induction or control condition and subsequently assessed participants' cognitive flexibility using an open-source version of the Wisconsin Card Sort task. Drawing on work in rodents, we hypothesized that stress would have stronger impairing effects on cognitive flexibility in men than women. As predicted, we found that stress impaired cognitive flexibility in men but did not significantly affect women. Our results thus indicate that stress exerts sex-specific effects on cognitive flexibility in humans and add to the growing body of research highlighting the need to consider sex differences in effects of stress.

    2015-08-01

    Previous research suggested that disgust may interfere with healthy sexual functioning by demonstrating that women with sexual pain disorders are characterized by heightened disgust propensity, relatively strong (physiological and subjective) disgust responses when exposed to sexual stimuli, and relatively strong automatic sex-disgust memory associations. To broaden the understanding of the relationship between sex and disgust, Study 1 tested the relationship between trait disgust and sexual functioning in both men (N = 109) and women (N = 187), and showed that specifically for women both relatively high disgust propensity and high sensitivity were related to lower sexual functioning. Study 2 focused on healthy young adults (N = 19 men and N = 24 women), and tested the relationship between trait disgust and automatic sex-disgust associations as well as the predictive value of trait disgust propensity for participants' level of sexual arousal while watching an erotic video. Participants completed a single-target Implicit Association Task and self-report measures of trait disgust propensity, disgust sensitivity, and sexual functioning. Furthermore, genital and subjective sexual arousal was measured, while participants were watching neutral and erotic video clips. Women showed stronger sex-disgust associations and reported higher disgust propensity than men. Overall, indices of trait disgust and sex-disgust associations were not strongly associated with sexual functioning or sexual arousability. Unexpectedly, specifically in men, high levels of trait disgust sensitivity predicted higher levels of genital and subjective sexual arousal. Overall, no strong evidence was found to support the view that, among young adults without sexual difficulties, high trait disgust or relatively strong automatic sex-disgust associations are associated with low sexual functioning and low sexual arousal.

    Klebel, H; Stronegger, W J

    1996-01-01

    27,344 persons in Styria participated in a study of the "Steirische Gesellschaft für Gesundheitsschutz" in Graz, within the framework of the project "Healthy communities" and were asked about diseases and health attitudes. All analyses were made separately for men and women and were adjusted for age and education. The goal of this study was a regional comparison of chronic diseases, risk factors, health consciousness and psychiatric complaints. Thus it should be possible to define the problematic regions with regard to health, in order to take the necessary political action to improve the situation. Men and women show a relative lack of health consciousness in the Weinbauregion and East Styria. Psychiatric complaints of women are more frequent in the Weinbauregion than the other areas. It appears that the healthier people live in the regions Mur/Mürztal and the Ennstal. Women have less risk factors than men, but have more psychiatric complaints. Men live less healthy lives in relation to their nutrition, risk avoidance and dental hygiene, except with respect to sports. Of the interviewed people from the surroundings of Graz 63% suffer from chronic disease, whilst in the Mur/Mürz- and Ennstal the respective figure is 56%. In the wine growing regions 54% of men drink alcohol daily, whereas in the Mur/Mürz- and Ennstal 42% of men drink alcohol daily. In the wine-growing regions 35% of the women and 50% of the men are overweight; in the Ennstal only 28% of the women are overweight but 45% of the men. Regular sports activities are undertaken by 35% of the women and 38% of the men in the Ennstal, as compared with 22% of the women and 27% of the men in East Styria. Insomnia was recorded in 29% of the women in East Styria, but in only 22% of the women in the Mur/Mürztal.

    2014-01-01

    Osteoporosis and consequent fracture are not limited to postmenopausal women. There is increasing attention being paid to osteoporosis in older men. Men suffer osteoporotic fractures about 10 years later in life than women, but life expectancy is increasing faster in men than women. Thus, men are living long enough to fracture, and when they do the consequences are greater than in women, with men having about twice the 1-year fatality rate after hip fracture, compared to women. Men at high risk for fracture include those men who have already had a fragility fracture, men on oral glucocorticoids or those men being treated for prostate cancer with androgen deprivation therapy. Beyond these high risk men, there are many other risk factors and secondary causes of osteoporosis in men. Evaluation includes careful history and physical examination to reveal potential secondary causes, including many medications, a short list of laboratory tests, and bone mineral density testing by dual energy X-ray absorptiometry (DXA) of spine and hip. Recently, international organizations have advocated a single normative database for interpreting DXA testing in men and women. The consequences of this change need to be determined. There are several choices of therapy for osteoporosis in men, with most fracture reduction estimation based on studies in women.

  8. Working through resistance in engaging boys and men towards gender equality and progressive masculinities.

    Ratele, Kopano

    2015-01-01

    Over the last two decades, a focus on challenging and transforming dominant forms of masculinity and engaging boys and men towards gender equality and healthy masculinities has permeated South African social and health sciences and the humanities. This focus on men and boys has also been evident in intervention and activist work. However, the turn to boys, men and masculinities has not gone without resistance, contestation and contradictions. A range of localised and global realities has frustrated much of the enthusiasm for rapid, sweeping and concrete changes regarding gender justice and the making of progressive masculinities. Among the discursive and material forces that oppose work that engages boys and men are those to do with income-related issues, race and racism, cultural traditions and gender itself. Because of this, it is contended that engagement with boys and men needs to consider not only gender but also economic inequality, poverty and unemployment, divisions created by race, and struggles around tradition. This paper discusses these forces that undermine and counteract work with boys and men and how we might work through resistance in engaging with men and boys. PMID:26073936

The campaign trains African American hair stylists to promote healthy behaviors with their clients through a “health chat” and by providing diabetes and hypertension risk assessment information and incentives.Consequences Since 1999, Healthy Hair has trained nearly 700 stylists and reached more than 14,000 clients in eight Michigan cities. Information collected through a client “Chat Form” suggests a number of positive behavioral results.Interpretation With nearly 60% of clients indicating that they have taken steps to prevent diabetes, hypertension, and chronic kidney disease or to seek a physician’s advice, the Healthy Hair program appears to be effective in the short term in prompting attention to healthy behaviors and increasing risk awareness.

  12. Androgen deficiency and aging in men.

    OpenAIRE

    Swerdloff, R S; Wang, C

    1993-01-01

    Androgen levels decrease with age in men. Androgen deficiency in men older than 65 years leads to asthenia, a decrease in muscle mass, osteoporosis, and a decrease in sexual activity. Androgen deficiency has been reported to cause changes in mood and cognitive function. The combination of these factors results in impaired quality of life in older men. Androgen replacement therapy in hypogonadal men increases bone and muscle mass, enhances muscle and cardiovascular function, and improves sexua...

    Osteoporosis has finally been recognized as an important disorder in men. Men have osteoporotic fractures about 10 years later in life than women. Owing to increasing life expectancy, more fractures are predicted. Important risk factors for men include advancing age, smoking or chronic obstructive pulmonary disease, glucocorticoid therapy, and androgen deprivation therapy for prostate cancer. Other groups at risk for osteoporosis include those with alcohol abuse, men on enzyme-inducing antise...

The present study aimed to compare plasma levels of cortisol, testosterone, dehydroepiandrosterone (DHEA, and prolactin in patients with schizophrenia and healthy individuals. Method. A total of 100 patients with schizophrenia disorder (69 men and 31 women and 190 healthy individuals (94 men and 96 women participated in this cross-sectional study. They were tested for hormone levels and completed demographic questionnaires. Data were analyzed using multivariate analysis of variance (MANOVA and one-way analysis of variance. Results. Serum testosterone level was significantly higher in men with schizophrenia than in healthy men. Women with schizophrenia had a significantly higher level of testosterone and lower level of prolactin compared to healthy women. There were no significant differences in hormone levels across various subtypes of schizophrenia. No significant differences also were observed in hormones levels in patients with first-episode schizophrenia disorder compared to those in patients with recurrent episodes. Conclusion. This study indicated that abnormal testosterone and prolactin levels might be associated with pathophysiology of schizophrenia disorder.

    Objective: To explore physical activity and eating behaviors among men following the implementation of a gender-sensitive, workplace health promotion program. Methods: Using a pre-post within-subjects design, computer-assisted telephone interviewing (CATI) was used to collect health-related information along with physical activity and fruit/vegetable intake at baseline and after 6 months. Results: At baseline, participants (N = 139) consumed 3.58 servings of fruit and vegetables/day and engaged in an average of 229.77 min/week moderate-vigorous physical activity (MVPA). At 6 months, daily fruit/vegetable intake did not increase, whereas MVPA increased by 112.3 min/week. Conclusions: The POWERPLAY program successfully increased weekly MVPA. Engaging men in health promotion can be a challenge; here, the workplace served as a valuable environment for achieving positive change. PMID:27281710

The aim of this study was to evaluate the association between the Trp64Arg polymorphism in the beta3-adrenergic receptor gene (ADRB3: rs4994 and BMI and serological and anthropometric data in healthy Japanese. Methods. Healthy Japanese recruited in a large-scale integrated manufacturing facility in Japan (=1355; age: 37.25 ± 9.43; BMI: 22.86 ± 3.46 were eligible for analysis. The anthropometric data and serological data were measured during a comprehensive health check, and a self-reporting questionnaire was used to assess lifestyle habits (current exercise, smoking status, alcohol intake, and working style and weight at age 20. Genotyping for the ADRB3 polymorphism was performed by PCR-RFLP method. Results. Among 1355 participants, the genotype frequencies of the Trp/Trp, Trp/Arg, and Arg/Arg variants were 920 (67.9%, 394 (29.1%, and 41 (3.05%, respectively. In the multivariate analysis, a multiple linear regression model in men for the adjustment of age, drinking habits, smoking habits, exercise habits, working status and serological measurements statistically showed an overall weak significance between annual BMI gain from age 20 and age, LDL or ADRB3 polymorphism. Conclusions. The level of LDL, age, and ADRB3 polymorphism (Arg/Arg genotype were statistically associated with annual BMI gain in Japanese men.

    1996-05-01

    In a retrospective study, we examined several determinants of basal fat oxidation in 720 healthy Caucasian volunteers. Adult men (n = 427) and women (n = 293) were characterized for resting energy expenditure and substrate oxidation by indirect calorimetry (after a 12-h overnight fast), peak O2 consumption by a treadmill test to exhaustion, body composition by hydrodensitometry, food intake from a 3-day food diary, and hormonal status by fasting hormone concentrations. Fat oxidation was negatively correlated with fat mass in men (r = -0.11; P consumption and fat-free mass in men (model R2 = 0.142) and by free thyroxine, fat-free mass, and fasting insulin in women (model R2 = 0.153). Relative rates of fat oxidation (fat oxidation adjusted for differences in resting energy expenditure) were not correlated with fat mass in either gender. Women showed a lower rate of basal fat oxidation (both absolute and adjusted) than did men. Our results show that fat oxidation is not greater in individuals with a greater fat mass. Furthermore, our results support a sexual dimorphism in basal rates of fat oxidation. PMID:8727562

    Preexposure prophylaxis has transformed HIV prevention, becoming widespread in communities of gay and bisexual men in the developed world in a short time. There is a broad concern that preexposure prophylaxis will discourage condom use among gay men (i.e., "risk compensation"). This commentary argues for broadening the focus on gay men's health beyond sexual health to address the holistic health and well-being of gay men. Gay men may benefit from being offered candid, nonjudgmental health promotion/HIV prevention messages not requiring condom use for anal sex. Lessons can be drawn from the family planning movement, which has undergone a similar shift in focus. The principle of patient centeredness supports such a shift in gay men's health toward the goal of providing men with the knowledge to evaluate various prevention approaches according to the specifics of their life circumstances and health needs. Bringing more nuance to discussions of sexual risk and sexual pleasure could facilitate more universally healthy attitudes regarding sex among gay men, in turn enabling healthier decisions more compatible with men's own values and preferences.

So nutraceuticals will definitely play promising and unique way of safer medicines. Nature is one of the most important resources of human foods and medicines. Rapidly increasing knowledge on nutrition, medicine, and plant has fortunately changed the concepts about food, health and, brought in a revolution on them. Nutritional therapy and phototherapy have emerged as new concepts of safer medicine. These systems have quickly and widely spread in recent years. Strong recommendations for consumption of nutraceuticals, natural plant foods, and the use of nutritional therapy and phototherapy have become progressively popular to improve health, and to prevent and treat diseases. Nutraceuticals used in various diseases, Alzheimer’s disease, cardiovascular disease, obesity, cancer, eye cycle, diabetes. The use of the dietary fiber, omega 3 fatty acid, antioxidant, probiotic, for the better human life possible. This review attempts to display and remark on these aspects. It summarizes the progress made on nutraceuticals, utritional therapy, health benefits, regulation and their promising approach. It also covers development stages of nutraceuticals.

    2014-11-01

    Men's help-seeking behaviour for health issues is apparent in advice columns in men's magazines. This study discursively analysed men's help-seeking letters and expert replies within two international and popular men's magazines, Men's Health and For Him Magazine or FHM. Findings showed that the texts reinforced hegemonic ideals. Letters positioning men as self-reliant, independently knowledgeable, stoic and avoiding associations with femininity were positively reinforced in expert replies, while other types of positioning were responded to with condescension or ridicule. Results suggest the policing of boundaries by 'experts' around unacceptable/acceptable enactments of masculinity, which may have implications for if, how and when men seek help from experts.

  16. Effects of Growth Hormone Administration on Muscle Strength in Men over 50 Years Old

    Directory of Open Access Journals (Sweden)

    A. B. W. Tavares

    2013-01-01

    Full Text Available Growth hormone (GH use has been speculated to improve physical capacity in subjects without GH deficiency (GHD through stimulation of collagen synthesis in the tendon and skeletal muscle, which leads to better exercise training and increased muscle strength. In this context, the use of GH in healthy elderly should be an option for increasing muscle strength. Our aim was to evaluate the effect of GH therapy on muscle strength in healthy men over 50 years old. Fourteen healthy men aged 50–70 years were evaluated at baseline for body composition and muscle strength (evaluated by leg press and bench press exercises, which focus primarily on quadriceps—lower body part and pectoralis major—upper body part—muscles, resp.. Subjects were randomised into 2 groups: GH therapy (7 subjects and placebo (7 subjects and reevaluated after 6 months of therapy. Thirteen subjects completed the study (6 subjects in the placebo group and 7 subjects in the GH group. Subjects of both groups were not different at baseline. After 6 months of therapy, muscle strength in the bench press responsive muscles did not increase in both groups and showed a statistically significant increase in the leg press responsive muscles in the GH group. Our study demonstrated an increase in muscle strength in the lower body part after GH therapy in healthy men. This finding must be considered and tested in frail older populations, whose physical incapacity is primarily caused by proximal muscle weakness. The trial was registered with NCT01853566.

    Full Text Available BACKGROUND: Men who have sex with men (MSM are a high-risk group for HIV. Implementation of effective preventive activities is an important way to combat HIV among MSM. However, in Ukraine there is no real HIV prevention policy among MSM and the need for its formulation is still open. MATERIAL AND METHODS: Analysis of legal acts, national reports and other official documents related to HIV prevention among MSM was carried out for Romania, Slovenia, the Netherlands, and Sweden.RESULTS: European countries use various approaches to HIV prevention among MSM: institutional, structural, and media approach.Countries under consideration have fully specified the minimum standard package for HIV prevention among MSM, who are defined as the highest priority group. Distinct strategies for MSM and ways to achieve them are outlined within the national plans and strategies for combating HIV/AIDS (Slovenia, Romania, the Netherlands. The National plan for HIV prevention among MSM will come into action in 2012 in Sweden. Countries, chosen for this study, use the principle of social contract by which the government provides subsidies and grants to nongovernmental organizations (NGOs working with MSM through its specialized health care units (Slovenia, Sweden, and sometimes only for one national NGO (the Netherlands. Outreach is the most common model of NGO’s activities.. In Sweden, MSM can get counseling and HIV testing in specialized HIV clinic for MSM. HIV prevention among MSM is run by representatives of NGOs through dating sites (Slovenia, Romania, through educating MSM and further promotion of healthy lifestyles among their friends. Along with the behavior modification activities, anti-discrimination strategies are used (Sweden, the Netherlands, Slovenia.CONCLUSIONS: Review of the regulatory frameworks, empowerment of NGOs, implementation of the social contract mechanisms, using interactive tools and providing education for MSM can be key points of HIV

    The long-term intake of a judiciously composed nutriceutical containing low-dose vitamins, antioxidants, minerals and particular herbal preparations seems justified for older persons who take medication, or who consume an unbalanced diet, or who are exposed to environmental toxins. Recent reports suggest these nutriceuticals may delay age-related diseases and the occurrence of cancer, and reduce mortality in apparently healthy ageing men. Food supplementation with a nutriceutical that was formulated particularly for ageing men should result in an increase of at least one quality-adjusted life year and may lower the financial and social burden of disease in elderly people.

    1985-11-01

    The acquired immunodeficiency syndrome (AIDS) is a major health problem for gay men in the United States. About three fourths of all reported cases have occurred in this population, and the number is projected to double in the next year. In Manhattan and San Francisco, AIDS is now the leading cause of premature mortality in men aged 25 to 44 years who have never married. In a sample of a cohort of gay men enrolled in a San Francisco clinic, 2.7% of the men had the syndrome and 26% had related conditions in 1984. Antibody to human T-lymphotropic virus, type III/lymphadenopathy-associated virus was found in sera from 67% of the men, including 58% of asymptomatic men. Behavioral factors associated with an increased risk of AIDS include large numbers of sexual partners, receptive anal intercourse, and "fisting." The adoption of safer lifestyles is currently the basis of attempts to control the syndrome in gay men. PMID:2996396

    Full Text Available Abstract Background Selenium (Se status in non-deficient subjects is typically assessed by the Se contents of plasma/serum. That pool comprises two functional, specific selenoprotein components and at least one non-functional, non-specific components which respond differently to changes in Se intake. A more informative means of characterizing Se status in non-deficient individuals is needed. Methods Multiple biomarkers of Se status (plasma Se, serum selenoprotein P [SEPP1], plasma glutathione peroxidase activity [GPX3], buccal cell Se, urinary Se were evaluated in relation to selenoprotein genotypes (GPX1, GPX3, SEPP1, SEP15, dietary Se intake, and parameters of single-carbon metabolism in a cohort of healthy, non-Se-deficient men (n = 106 and women (n = 155. Conclusions Plasma Se concentration was 142.0 ± 23.5 ng/ml, with GPX3 and serum-derived SEPP1 calculated to comprise 20% and 34%, respectively, of that total. The balance, comprised of non-specific components, accounted for virtually all of the interindividual variation in total plasma Se. Buccal cell Se was associated with age and plasma homocysteine (hCys, but not plasma Se. SEPP1 showed a quadratic relationship with body mass index, peaking at BMI 25-30. Urinary Se was greater in women than men, and was associated with metabolic body weight (kg0.75, plasma folate, vitamin B12 and hCys (negatively. One GPX1 genotype (679T/T was associated with significantly lower plasma Se levels than other allelic variants. Selenium intake, estimated from food frequency questionnaires, did not predict Se status as indicated by any biomarker. These results show that genotype, methyl-group status and BMI contribute to variation in Se biomarkers in Se-adequate individuals.

    The present study investigated people's perception of their own as compared to their peers' healthy eating and related these perceptions to actual healthy eating, BMI, and subsequent healthy eating behavior. Data were collected within the framework of the longitudinal cohort study Konstanz Life Study (T1: N = 770; T2: N = 510). Our results demonstrated an optimistic bias on the group level. Specifically, people rated their own eating behavior as healthier on average than that of their average peers. This comparative optimism occurred even when actual healthy eating was unfavorable and BMI was high. However, it increased with actual healthy eating behavior. Importantly, optimistic perceptions were positively related to the intention to eat healthily and healthy eating six months later. Hence, the results suggest that an optimistic comparative view of one's own healthy eating is grounded in reality and boosts rather than deters subsequent health behavior. This implies that there might not be a need to reduce optimistic perceptions of healthy eating behavior.

    This article examines the increasing life expectancy of Japanese men and women in relation to their health from 1986 to 2004. We computed healthy life expectancy for seven available time-points using the prevalence-based Sullivan method. The results showed that, for both sexes and at all ages, the gains in life expectancy prior to 1995 were mostly in years of good self-rated health, while the gains thereafter were in years of poor self-rated health. The exception was for women at age 85, amon...

    We have previously found that licorice can reduce serum testosterone in healthy men. These results were not confirmed in another study, where the same amounts of licorice did not decrease salivary testosterone values. In the actual study we treated more cases with the same amount of licorice and reproduced our previous data. The mean testosterone values decreased by 26 % after one week of treatment (p < 0.01). There was also a significant increase in 17-OHP and LH concentrations and a slight, but not significant decrease in free testosterone. Licorice treatment, in addition, did not affect the response of testosterone and 17-OHP to stimulation with beta-HCG. PMID:14520600

    Full Text Available Abstract Background The 'Healthy Dads, Healthy Kids' program was designed to help overweight fathers lose weight and positively influence the health behaviors of their children. The aim of the current study was to evaluate the previously established program in a community setting, in a large effectiveness trial. Methods/Design The Healthy Dads, Healthy Kids community trial consists of three stages: (i Stage 1 - program refinement and resource development (ii Stage 2 - community randomized controlled trial (iii Stage 3 - community effectiveness trial. The program will be evaluated in five Local Government Areas in the Hunter Valley Region of NSW, Australia. For the community randomized controlled trial, 50 overweight/obese men (aged 18-65 years from one Local Government Area with a child aged between 5-12 years of age will be recruited. Families will be randomized to either the program or a 6-month wait-list control group. Fathers and their children will be assessed at baseline, post-intervention (3-months and 6-months. Inclusion criteria are: body mass index 25-40 kg/m2; no participation in other weight loss programs during the study; pass a health-screening questionnaire; and access to a computer with Internet facilities. In the community trial, the program will be evaluated using a non-randomized, prospective design in five Local Government Areas. The exclusion criteria is body mass index 2 or lack of doctor's approval. Measures will be collected at baseline, 3-, 6- and 12-months. The program involves fathers attending seven face-to-face group sessions (three with children over 3-months. Measures: The primary outcome is fathers' weight. Secondary outcomes for both fathers and children include: waist circumference, blood pressure, resting heart rate, physical activity, sedentary behaviors and dietary intake. Father-only measures include portion size, alcohol consumption, parenting for physical activity and nutrition and parental engagement

    Full Text Available OBJECTIVE: To determine energy expenditure in kilocalories (kcal during sexual activity in young healthy couples in their natural environment and compare it to a session of endurance exercise. METHODS: The study population consisted of twenty one heterosexual couples (age: 22.6 ± 2.8 years old from the Montreal region. Free living energy expenditure during sexual activity and the endurance exercise was measured using the portable mini SenseWear armband. Perceived energy expenditure, perception of effort, fatigue and pleasure were also assessed after sexual activity. All participants completed a 30 min endurance exercise session on a treadmill at a moderate intensity. RESULTS: Mean energy expenditure during sexual activity was 101 kCal or 4.2 kCal/min in men and 69.1 kCal or 3.1 kCal/min in women. In addition, mean intensity was 6.0 METS in men and 5.6 METS in women, which represents a moderate intensity. Moreover, the energy expenditure and intensity during the 30 min exercise session in men was 276 kCal or 9.2 kCal/min and 8.5 METS, respectively and in women 213 kCal or 7.1 kCal/min and 8.4 METS, respectively. Interestingly, the highest range value achieved by men for absolute energy expenditure can potentially be higher than that of the mean energy expenditure of the 30 min exercise session (i.e. 306.1 vs. 276 kCal, respectively whereas this was not observed in women. Finally, perceived energy expenditure during sexual activity was similar in men (100 kCal and in women (76.2 kCal when compared to measured energy expenditure. CONCLUSION: The present study indicates that energy expenditure during sexual activity appears to be approximately 85 kCal or 3.6 kCal/min and seems to be performed at a moderate intensity (5.8 METS in young healthy men and women. These results suggest that sexual activity may potentially be considered, at times, as a significant exercise.

    Full Text Available Introduction A need for research of the olfactory function exists in everyday clinical work. The aim of this study was to determine standards for perception and identification thresholds regarding olfactory substances in healthy subjects in regard to their age. Material and methods The research included 120 healthy examinees (60 women and 60 men classified according to age into three age groups (20-30, 31-40, 41-50 years of age. This examination was done using Fortunato-Niccolini's method. Results and discussion The results of this work show that olfactory function becomes significantly weaker after the age of forty. Thresholds of perception in correlation with thresholds of identification for examined olfactory substances are significantly lower in older age groups. Conclusion A gradual loss of olfactory capability with age can be explained by gradual destruction of olfactory cells and fibres of olfactory nerves during life.

  16. Prostate cancer in men of African origin.

    Men of African origin are disproportionately affected by prostate cancer: prostate cancer incidence is highest among men of African origin in the USA, prostate cancer mortality is highest among men of African origin in the Caribbean, and tumour stage and grade at diagnosis are highest among men in sub-Saharan Africa. Socioeconomic, educational, cultural, and genetic factors, as well as variations in care delivery and treatment selection, contribute to this cancer disparity. Emerging data on single-nucleotide-polymorphism patterns, epigenetic changes, and variations in fusion-gene products among men of African origin add to the understanding of genetic differences underlying this disease. On the diagnosis of prostate cancer, when all treatment options are available, men of African origin are more likely to choose radiation therapy or to receive no definitive treatment than white men. Among men of African origin undergoing surgery, increased rates of biochemical recurrence have been identified. Understanding differences in the cancer-survivorship experience and quality-of-life outcomes among men of African origin are critical to appropriately counsel patients and improve cultural sensitivity. Efforts to curtail prostate cancer screening will likely affect men of African origin disproportionately and widen the racial disparity of disease.

The impulsivity was measured by means of the Barratt Impulsivity Scale, version 11 (BIS-11, a widely used self-report questionnaire, and the platelet SERT was evaluated by means of the specific binding of 3H-paroxetine (3H-Par to platelet membranes, according to standardized protocols. The results showed that women had a higher BIS-11 total score than men, and also higher scores of two factors of the same scale: the motor impulsivity and the cognitive complexity. The analysis of the correlations revealed that the density of the SERT proteins, as measured by the maximum binding capacity (Bmax of 3H-Par, was significantly and positively related to the cognitive complexity factor, but only in men. Men showed also a significant and negative correlation with the dissociation constant, Kd, of (3H-Par binding, and the motor impulsivity factor. These findings suggest that women are generally more impulsive than men, but that the 5-HT system is more involved in the impulsivity of men than in that of women.Keywords: impulsivity, gender, serotonin transporter, Barratt Impulsivity Scale, platelets, 3H-paroxetine

    The dominant evolutionary theory of physical attraction posits that attractiveness reflects physiological health, and attraction is a mechanism for identifying a healthy mate. Previous studies have found that perceptions of the healthiest body mass index (weight scaled for height; BMI) for women are close to healthy BMI guidelines, while the most attractive BMI is significantly lower, possibly pointing to an influence of sociocultural factors in determining attractive BMI. However, less is known about ideal body size for men. Further, research has not addressed the role of body fat and muscle, which have distinct relationships with health and are conflated in BMI, in determining perceived health and attractiveness. Here, we hypothesised that, if attractiveness reflects physiological health, the most attractive and healthy appearing body composition should be in line with physiologically healthy body composition. Thirty female and 33 male observers were instructed to manipulate 15 female and 15 male body images in terms of their fat and muscle to optimise perceived health and, separately, attractiveness. Observers were unaware that they were manipulating the muscle and fat content of bodies. The most attractive apparent fat mass for female bodies was significantly lower than the healthiest appearing fat mass (and was lower than the physiologically healthy range), with no significant difference for muscle mass. The optimal fat and muscle mass for men's bodies was in line with the healthy range. Male observers preferred a significantly lower overall male body mass than did female observers. While the body fat and muscle associated with healthy and attractive appearance is broadly in line with physiologically healthy values, deviations from this pattern suggest that future research should examine a possible role for internalization of body ideals in influencing perceptions of attractive body composition, particularly in women.
