Serum magnesium and lipids: More clarity is needed

2007

Resistance training status modifies inflammatory response to explosive and hypertrophic resistance exercise bouts.

2017

The purpose of the present study was to examine the immediate and prolonged immune response in circulating cytokine and adipocytokine concentrations after two different resistance exercise bouts: hypertrophic (HYP1, 5 × 10, 80% of 1RM) and maximal explosive (POW1, 10 × 5, 60% of 1RM) resistance exercise bouts and how 12 weeks of resistance training (RT) modifies these responses (HYP2, POW2). Eight men completed the study. RE-induced interleukin-6 (IL-6), interleukin-1β (IL-1β), interleukin-1 receptor antagonist (IL-1ra), monocyte-chemoattractant protein-1 (MCP-1), leptin, resistin, and adiponectin were measured before (PRE) and immediately (POST0), 24 (POST24) and 48 (POST48) hours after RE…

Difference in body weight between American and Italian women with polycystic ovary syndrome: influence of the diet.

2003

BACKGROUND The study aim was to determine differences in body mass in two populations of women (USA and Italy) with polycystic ovary syndrome (PCOS), and to assess the effect of diet on body mass and cardiovascular risk factors. METHODS Pools of women with PCOS from the USA (n = 343) and Italy (n = 301), seen between 1993 and 2001, were available for assessment. From these populations, 20 women who were seen consecutively in 2001 at each site had detailed analyses of diet and cardiovascular risk factors. RESULTS In the entire group, American women had a significantly higher body mass compared with Italian women (P < 0.01). Also, the 20 women consecutively evaluated in the USA had a signific…

How should we manage atherogenic dyslipidemia in women with polycystic ovary syndrome?

2007

Despite their young age, women with polycystic ovary syndrome (PCOS) have increased cardiovascular risk. Besides normal concentrations of low-density lipoprotein (LDL) cholesterol, dyslipidemia is very common and includes elevated triglyceride levels and low high-density lipoprotein cholesterol concentrations. Recent findings also showed that women with PCOS have qualitative LDL alterations, with increased levels of atherogenic small, dense LDL particles. Such lipid abnormalities constitute a common form of dyslipidemia, the so-called atherogenic lipoprotein phenotype (ALP), associated with a greater cardiovascular risk. Weight reduction and increased physical activity may constitute first-…

Androgenic-anabolic steroid effects on serum thyroid, pituitary and steroid hormones in athletes.

1987

Endocrine responses in seven power athletes were investigated during a 12 week strength training period, when the athletes were taking high doses of androgenic-anabolic steroids, and during the 13 weeks following drug withdrawal. During the use of steroids significant decreases (P less than 0.05 to 0.001) in the serum concentrations of thyroid stimulating hormone, thyroxine, triidothyronine, free thyroxine, and thyroid hormone-binding globulin (TBG) were found, whereas the value of triidothyronine uptake increased (P less than 0.001). In relation to the changes in the thyroid function parameters measured, we suggest that the primary target of androgen action was TBG biosynthesis. In five of…

Association between cardiorespiratory fitness and metabolic health in overweight and obese adults

2021

Background Cardiorespiratory fitness (CRF) has been inversely associated with insulin resistance and clustering of cardiometabolic risk factors among overweight and obese individuals. However, most previous studies have scaled CRF by body mass (BM) possibly inflating the association between CRF and cardiometabolic health. We investigated the associations of peak oxygen uptake (V O2peak) and peak power output (Wpeak) scaled either by BM-1, fat free mass (FFM-1), or by allometric methods with individual cardiometabolic risk factors and clustering of cardiometabolic risk factors in 55 overweight or obese adults with metabolic syndrome. Methods V O2peak and Wpeak were assessed by a maximal cycl…

Cortical stimulation and reflex excitability of spinal cord neurones in man.

1995

The H reflex technique was used to evaluate the influence exerted by cortical conditioning on the excitability of the alpha-motoneurone pool and on IA interneuronal activity (reciprocal inhibition). In ten subjects at absolute rest electrical and magnetic stimulation of the motor cortex was transcranially applied during flexor carpi radialis H reflex eliciting and in conditions of reciprocal inhibition induced by radial nerve stimulation. The time courses showed that at intensities below motor threshold, electrical brain conditioning induced an increase in the amplitude of the test reflex when the cortical shock was given 4 ms after the test H reflex. On the contrary, reciprocal inhibition …

Associations of Sex Hormones and Hormonal Status With Arterial Stiffness in a Female Sample From Reproductive Years to Menopause

2021

Objective: Loss of sex hormones has been suggested to underlie menopause-associated increment in cardiovascular risk. We investigated associations of sex hormones with arterial stiffness in 19–58-years-old women. We also studied associations of specific hormonal stages, including natural menstrual cycle, cycle with combined oral contraceptives (COC) and menopausal status with or without hormone therapy (HT), with arterial stiffness. Methods: This study includes repeated measurements of 65 healthy women representing reproductive (n=16 natural, n=10 COC-users) and menopause (n=5 perimenopausal, n=26 postmenopausal, n=8 HT-users) stages. Arterial stiffness outcomes were aortic pulse wave veloc…

Polar Bear in 'Fortitude'. Affective Aesthetics and Politics of Climate Change

2021

In the first season of the television Eco Noir crime series “Fortitude” (2015) the polar bear appears as a sticky object that embodies an ambiguous affective charge as an icon of global warming. This article discusses the ways in which the polar bear evokes viewer affect in the series through two discourses. The first one relates to violence, essentially present in crime narratives, and how the human and nonhuman animal are positioned in relation to global warming, violence and each other. It raises questions of place and belonging in a local and global context and examines how the polar bear is constructed in terms of stranger danger and victimization in relation to human animals and the t…

The impurity of praxis : Arendt and Agamben

2023

AbstractIf politics is understood as a foundational and open-ended activity, a general problem that arises from such a framing concerns the question of how to sustain the possibility of continuous openings without converting action into permanence and closure. In this article, we approach this problematic by treating Hannah Arendt as an exemplary figure in the current of political thought that emphasizes the indeterminate nature of action. We focus more specifically on how Arendt addressed the question of sustaining action by exploring the role of forgiveness, promises, divided power, and principles of action in her thought. While we show that the task of sustaining the indeterminacy of act…
