Maternal effects in quail and zebra finches: behavior and hormones.

2013

8 pages; International audience; Maternal effects are influences of parents on offspring phenotype occurring through pathways other than inherited DNA. In birds, two important routes for such transmission are parental behavior and non-DNA egg constituents such as yolk hormones. Offspring traits subject to parental effects include behavior and endocrine function. Research from the Adkins-Regan lab has used three avian species to investigate maternal effects related to hormones and behavior. Experiments with chickens and Japanese quail have shown that maternal sex steroids can influence sex determination to produce biased offspring sex ratios. Because all birds have a ZZ/ZW chromosomal sex de…

Serum sex-hormone binding globulin and cortisol concentrations are associated with overreaching during strenuous military training

2011

The purpose was (a) to study the effect of an 8-week Finnish military basic training period (BT) on physical fitness, body composition, mood state, and serum biochemical parameters among new conscripts; (b) to determine the incidence of overreaching (OR); and (c) to evaluate whether initial levels or training responses differ between OR and noOR subjects. Fifty-seven males (19.7 ± 0.3 years) were evaluated before and during BT. Overreaching subjects had to fulfill 3 of 5 criteria: decreased aerobic physical fitness (VO2max), increased rating of perceived exertion (RPE) in 45-minute submaximal test at 70% of VO2max or sick absence from these tests, increased somatic or emotional symptoms of …

Effect of time-of-day-specific strength training on serum hormone concentrations and isometric strength in men.

2007

A time-of-day influence on the neuromuscular response to strength training has been previously reported. However, no scientific study has examined the influence of the time of day when strength training is performed on hormonal adaptations. Therefore, the primary purpose of this study was to examine the effects of time-of-day-specific strength training on resting serum concentrations and diurnal patterns of testosterone (T) and cortisol (CORT) as well as maximum isometric strength of knee extensors. Thirty eight diurnally active healthy, previously untrained men (age 20-45 yrs) underwent a ten-week preparatory strength training period when sessions were conducted between 17:00-19:00 h. Ther…

Oggettivismo e relativismo: alcune definizioni e una proposta

Figure di città. Spazi urbani e discorsi sociali

2013

Questo libro dialoga con le altre discipline che nell’epoca contemporanea indagano sui problemi scottanti della metropoli e della megalopoli, dello sprawl urbano e degli slums, delle reti mediatiche e della sfera immaginaria che esse generano. E nello stesso tempo prova a individuare i momenti chiave – e i punti critici – che sono via via emersi negli studi semiotici sulla città. Lo scopo del libro è appunto quello di dissodare un campo entro cui si innestano e proliferano una serie di figure di città, immagini e segni d’ogni tipo che, nel loro intreccio, vanno a costituire lo spessore della nostra vita quotidiana. Sorvegliato da una intelaiatura teorica tanto rigorosa quanto dinamica, lo s…

Validation of the German version of the ‘Hypogonadism Related Symptom Scale’ (HRS) in andrological patients with infertility, HIV infection and metab…

2013

Summary As commonly used self-reported screening instruments for male hypogonadism demonstrated lack of specificity, a Hypogonadism Related Symptom Scale (HRS) was developed in 2009 as a novel self-rating screening tool. As the questionnaire has not been validated, the purpose of our study was to perform a validation in patients presenting with different disorders (e.g. infertility, HIV infection or metabolic syndrome) and disease-related risk to develop hypogonadism. Two hundred and eighteen patients aged 19–71 years (40.1 ± 9.5) who completed the HRS and other common questionnaires [International Index Of Erectile Function (IIEF), National Institutes of Health Chronic Prostatitis Symptom …

Low estradiol-to-testosterone ratio is associated with oligo-anovulatory cycles and atherogenic lipidic pattern in women with polycystic ovary syndro…

2010

The estradiol-to-testosterone (E2/T) ratio has been investigated in different diseases but few in vivo data are available with regard to its role in women with ovary syndrome (PCOS). The aim of this study was to evaluate the role of the E2/T ratio in the ovulatory function and metabolic pattern in such women.We retrospectively evaluated hyperandrogenemia, clinical hyperandrogenism, ovarian morphology, hypothalamo-hypophyseal axis and metabolic syndrome parameters in a cohort of 202 consecutive women affected by PCOS. An oral glucose tolerance test measured areas under the curve for insulin (AUC(2hIRI)), for glucose (AUC(2hglucose)), and the HOMA-IR and Matsuda index of insulin resistance we…

The effects of 12-week progressive strength training on strength, functional capacity, metabolic biomarkers, and serum hormone concentrations in heal…

2018

Previous findings suggest that performing strength training (ST) in the evening may provide greater benefit for young individuals. However, this may not be optimal for the older population. The purpose of this study was to compare the effects of a 12-week ST program performed in the morning vs. evening on strength, functional capacity, metabolic biomarker and basal hormone concentrations in older women. Thirty-one healthy older women (66 ± 4 years, 162 ± 4 cm, 75 ± 13 kg) completed the study. Participants trained in the morning (M) (07:30, n = 10), in the evening (E) (18:00, n = 10), or acted as a non-training control group (C) (n = 11). Both intervention groups performed whole-body strengt…

Acute Hormonal Responses to Heavy Resistance Exercise in Men and Women at Different Ages

1995

To examine acute endogenous hormonal responses to heavy resistance exercise eight young women (YW) and eight young men (YM) in the 30-year age group, seven middle-aged women (MW) and eight middle-aged men (MM) in the 50-year age group as well as eight elderly women (EW) and eight elderly men (EM) in the 70-year age group performed a heavy resistance exercise session with three different exercises (bench press, sit-up exercise and bilateral leg press). The relative loading intensity and volume of the exercise session were kept the same for each subject so that they performed each of the 5 sets of each exercise with the maximal load possible for 10 repetitions per set (10 repetition maximum).…

Migrazioni ed insediamenti informali: riflessioni sul caso siciliano

2022

Over the last fifty years, many European regions in the Mediterranean area, historically considered as areas of origin of international migration flows, have been transformed into places of reception. At the basis of this mobility is, among many factors, the demand, by a variable and globalised economy, for 'easy' labour, mostly made up of new immigrants, instrumental to that particular local economic system. Analysing the spatial dimension of the phenomenon, it highlights how the inadequacy and insufficiency of reception places and the increase in eviction phenomena contribute to the significant increase in the phenomenon of informal settlements in peripheral urban contexts, making it diff…
