Morphological description of hypothetical cellulite starting unit. The first step to explain cellulite development

2017

Introduction: Cellulite is a complex pathology that affects about 85% of women. The origin of cellulite is poorly understood, even if some studies describe different hypotheses based on the observation of subcutaneous architecture, vascular and lymphatic patterns. Material and methods: in this work an ultra-structural description of cellulite specimens, harvested from fifteen healthy women affected by first degree cellulite, was provided. Specimens were harvested from trochanter, after local anaesthesia using punch biopsy. Samples were fixated, immediately after biopsy, in glutaraldehyde 2% and processed for electron microscopy. Results: with scanning and transmission electron microscopy it…

Green and Integrated Wearable Electrochemical Sensor for Chloride Detection in Sweat

2022

Wearable sensors for sweat biomarkers can provide facile analyte capability and monitoring for several diseases. In this work, a green wearable sensor for sweat absorption and chloride sensing is presented. In order to produce a sustainable device, polylactic acid (PLA) was used for both the substrate and the sweat absorption pad fabrication. The sensor material for chloride detection consisted of silver-based reference, working, and counter electrodes obtained from upcycled compact discs. The PLA substrates were prepared by thermal bonding of PLA sheets obtained via a flat die extruder, prototyped in single functional layers via CO2 laser cutting, and bonded via hot-press. The effect of co…

Effects of three different water temperatures on dehydration in competitive swimmers

2011

Summary Aims The purpose of this study was to evaluate the effects of three different water temperatures on physiological responses (dehydration, sweat rate, urine output, rectal temperature and plasma electrolytes) of competitive athletes during a “simulated” race of 5 km in an indoor swimming pool. Methods Nine male competitive master swimmers swam 5 km with the water at temperatures of 23, 27 and 32 C. Immediately before (Pre) and after (Post) each trial, samples of blood and urine were collected, body weight was recorded and rectal temperature was measured. The dehydration percentage and sweat rate were the highest at 32 C and the lowest at 23 C (23 C: −0.9 ± 0.5; 27 C: −1.3 ± 0.6; 32 C…

Hyperhidrosis

2009

Sweating is a physiological and vital process. The basic distinction is made between two types of sweating: thermoregulatory and emotional sweating. Most of the sweat glands are of the eccrine type. They produce a thin secretion that is hypotonic to plasma (e1). Eccrine sweat glands are distributed all over the body; their highest density is in the axillary region, on the palms of the hands, and on the soles of the feet (1). Their main function is thermoregulation. Apocrine sweat glands are found primarily in the axillae and the urogenital region. These scent glands become active during puberty and secrete a viscous fluid. They are responsible for a person’s "personal," occasionally unpleas…

Menopausal symptoms and cardiometabolic risk factors in middle-aged women : A cross-sectional and longitudinal study with 4-year follow-up

2023

Objective To study associations of menopausal symptoms with cardiometabolic risk factors. Study design A cross-sectional and longitudinal study of a representative population sample of 1393 women aged 47–55 years with a sub-sample of 298 followed for four years. The numbers of vasomotor, psychological, somatic or pain, and urogenital menopausal symptoms were ascertained at baseline through self-report. Their associations with cardiometabolic risk factors were studied using linear regression and linear mixed-effect models. Models were adjusted for age, menopausal status, body mass index, the use of hormonal preparations, education, smoking, and alcohol consumption. Main outcome measures Card…
