A growing body of evidence suggests that humans can communicate socially relevant information, such as aggression, dominance and readiness for competition, through chemosensory signals. Androstadienone (androsta-4,16,-dien-3-one), a testosterone-derived compound found in men's axillary sweat, is a main candidate for a human pheromone that may convey such information. The current study aimed to investigate whether androstadienone serves as a chemosignaling threat cue to men, thus triggering avoidance behavior during competitive interaction with another man...

Hypohidrotic ectodermal dysplasia (HED), also known as anhidrotic ectodermal dysplasia, is characterized by the clinical manifestations of less sweat or no sweat, sparse or no hair, tooth agenesis and/or abnormal tooth morphology. The characteristics of alpaca ear hair differ from the back hair. The ectodysplasin A (EDA) signaling pathway has a regulatory effect on skin development and hair growth. The aim of the present study was to study the effects of EDA on alpaca hair growth by examining the mRNA and protein expression levels of EDA in alpaca ear and back skin by reverse transcription‑quantitative polymerase chain reaction and western blot analysis, respectively...

The androgen derivative androstadienone (AND) is a substance found in human sweat and thus may act as human chemosignal. With the current experiment, we aimed to explore in which way AND affects interference processing during an emotional Stroop task which used human faces as target and emotional words as distractor stimuli. This was complemented by functional magnetic resonance imaging (fMRI) to unravel the neural mechanism of AND-action. Based on previous accounts we expected AND to increase neural activation in areas commonly implicated in evaluation of emotional face processing and to change neural activation in brain regions linked to interference processing...

BACKGROUND: Recurrent airway infections are common in patients with Down's syndrome (DS). Hence, ruling out Cystic Fibrosis (CF) in these patients is often required. In the past, the value of sweat testing - the gold standard to diagnose CF - has been questioned in DS as false positive results have been reported. However, these reports are based on measurements of sweat osmolality or sodium concentrations, not chloride concentrations. This study analyses sweat secretion rate and chloride concentration in sweat samples of patients with DS in comparison to healthy controls...

A 46-year-old healthy man developed respiratory distress, night sweats, fever, and weight loss after using electronic cigarettes (e-cigs) for approximately 1 month. He presented to the hospital when the symptoms worsened 2 months after onset. The findings of bronchoalveolar lavage (BAL) fluid examination and the following transbronchial lung biopsy examination led to the diagnosis of acute alveolitis: intra-alveolar fibrosis accompanied with exudate containing abundant lipid-laden macrophages, eosinophils, and neutrophils...

The purpose of this study was to determine the time course for the previously reported reduction in sweat sodium ion concentration during heat acclimation. Four healthy volunteers completed 7 consecutive days of heat acclimation which included 2h of treadmill walking in a 40°C and 40% relative humidity environment. A modified constant hyperthermia protocol was used as workloads were increased each day to maintain a constant core temperature over the 7 days of heat acclimation. Forearm sweat was collected 3 times during each 2h exercise bout on days 1, 3, 5, and 7 of heat acclimation...

The androgen derivative androstadienone (AND) is present in human sweat and may act as human chemosignal. Though effects of AND have been reported with respect to emotional and cognitive processes, results have been highly inconsistent. For this reason, it is likely that AND-action is dependent on modulatory factors. Here we wanted to specifically investigate the impact of genotypic variations of the AND-receptor OR7D4, as well as the influence of participant sex and concomitant hormonal fluctuations on AND-action during emotional interference processing, olfactory performance and mood assessments...

Migraine related vertigo (MRV) is largely accepted in the vestibular community and probably represents the second most common cause of vertigo after benign positional vertigo by far exceeding Meniere's disease. The data on vestibular migraine management is still relatively poor, despite its enormous importance in daily practice. A 55-year old male presented with history of giddiness, imbalance, sweating and sensation of nausea with severe pulsating headache of one day duration. Ear, Nose and Throat examination was normal...

NEW FINDINGS: What is the central question of this study? It remains to be determined whether type 2 diabetes attenuates muscarinic and nicotinic cutaneous vasodilatation and sweating as well as purinergic cutaneous vasodilatation. What is the main finding and its importance? We show that type 2 diabetes specifically attenuates purinergic cutaneous vasodilatation without influencing muscarinic and nicotinic cutaneous vasodilatation and sweating. Our results provide valuable new information regarding the receptor-specific influence of type 2 diabetes on microvascular and sudomotor function...

Despite tremendous recent efforts, non-invasive sweat monitoring is still far from delivering its early analytical promise. Here, we describe a flexible epidermal microfluidic detection platform fabricated through hybridization of lithographic and screen-printed technologies for efficient sweat sampling and continuous real-time electrochemical monitoring of sweat glucose and lactate levels. This soft, skin-mounted device judiciously merges lab-on-a-chip and electrochemical detection technologies, integrated with a miniaturized flexible electronic board for real-time wireless data transmission to a smart device...

It has long been known from microneurographic recordings in human subjects that activity of postganglionic sympathetic axons occurs as spontaneous bursts, with muscle sympathetic nerve activity (MSNA) exhibiting strong cardiac rhythmicity via the baroreflex and skin sympathetic nerve activity (SSNA) showing much weaker cardiac modulation. Here we review the firing properties of single sympathetic neurons, obtained using highly selective microelectrodes. Individual vasoconstrictor neurons supplying muscle or skin, or sudomotor neurones supplying sweat glands, always discharge with a low firing probability (~30%) and at very low frequencies (~0...

BACKGROUND: Disseminated Lyme disease can be difficult to diagnose, as it begins with nonspecific signs and symptoms, which, if not treated correctly, can lead to atrioventricular conduction blocks and meningitis. In addition, the diagnosis can be further complicated by potentially false-positive test results. CASE REPORT: We report a case of early-disseminated Lyme disease presenting with Borrelia meningitis and concomitant Lyme carditis, which was misdiagnosed as mononucleosis...

OBJECTIVE: Hyposmia is one of the earliest non-motor features of Parkinson's disease (PD) and can precede the onset of motor symptoms by years. Most of the current olfactory detection tests are targeted at Western populations. The exact relationship between hyposmia and cognitive impairment is unknown. The purpose of the study was to find bromines that can effectively identify olfactory dysfunction and investigate the relationship between hyposmia and cognitive function in early, non-demented, drug-naïve patients with PD in the People's Republic of China...

It is common practice in India to consume the dairy drink buttermilk as a way of mitigating occupational heat strain. This paper explores the thermoregulatory and hydration benefits of drinking buttermilk but also the impacts of work in a hot environment on the gut microbiota, renal and cognitive function. Twelve healthy participants were subjected to a 3-hour period of medium load physical intermittent work in a climatic chamber (34°C, 60 % RH). The subjects were given water, buttermilk (700 ml) or no rehydration at random...

A hot environment combined with physically demanding tasks can subject workers to a higher risk of heat stress. A series of regulations and guidelines have been proposed to design appropriate anti-heat stress work uniform to reduce body heat strain. The present study aimed to examine heat strain recovery in different anti-heat stress clothing ensembles after work to exhaustion in the heat. 10 healthy males performed intermittent treadmill running/walking to exhaustion, followed by 30min passive recovery sitting in a climatic chamber, which simulated the hot and humid outdoor environment (34°C temperature, 60% relative humidity, 0...

BACKGROUND: Arrhythmias in horses may require long term anti-arrhythmic therapy. Unfortunately, oral anti-arrhythmic drugs for use in horses are currently scarce. In human patients and small animals, sotalol, a β-blocker with class III anti-arrhythmic properties, is often used for long-term treatment. OBJECTIVES: To determine the pharmacokinetics of sotalol at multiple oral dosages in unfasted horses, as well as the effects on electro- and echocardiographic measurements, right atrial and ventricular monophasic action potential (MAP) and effective refractory period (ERP)...

The combination of low-load resistance training [or more recently, neuromuscular electrical stimulation (NMES)] with a moderate local blood flow restriction (BFR) is becoming a widespread training and rehabilitation method. Scientific data indicate the overall safety of BFR, at least in healthy young people. However, it has been associated with side effects, usually minor, and further research is warranted regarding the safety and efficacy of this technique, especially in clinical populations. We found 3 syncope/presyncopal episodes among 21 healthy people (9 men), all occurring in men and during familiarization sessions (in which BFR was applied alone) but not thereafter (BFR sessions combined with NMES): 1 subject experienced a brief syncope and 2 other subjects exhibited presyncopal symptoms (sweating, lightheadedness, and pallor)...
