Three hypotheses exist to explain how meteorological variables drive the amount and concentration of solute-enriched water from rock glaciers: (1) Warm periods cause increased subsurface ice melt, which releases solutes; (2) rain periods and the melt of long-lasting snow enhance dilution of rock-glacier outflows; and (3) percolation of rain through rock glaciers facilitates the export of solutes, causing an opposite effect as that described in hypothesis (2). This lack of detailed understanding likely exists because suitable studies of meteorological variables, hydrologic processes and chemical characteristics of water bodies downstream from rock glaciers are unavailable...

BACKGROUND: Oxazolone-induced colitis has been frequently used in literature as a model of IBD, but insights into the underlying immune response and pathological features are surprisingly still very limited. Vagus nerve stimulation (VNS) has proven to be effective in innate and Th1/Th17 predominant inflammatory models, including pre-clinical models of colitis, however to what extent VNS is also effective in ameliorating Th2-driven colitis remains to be studied. In the present study, we therefore further characterized the immune response in oxazolone-induced colitis and investigated the potential therapeutic effect of VNS...

The non-equilibrium dynamics of quantum many-body systems is one of the most fascinating problems in physics. Open questions range from how they relax to equilibrium to how to extract useful work from them. A critical point lies in assessing whether a system has conserved quantities (or 'charges'), as these can drastically influence its dynamics. Here we propose a general protocol to reveal the existence of charges based on a set of exact relations between out-of-equilibrium fluctuations and equilibrium properties of a quantum system...

Although brown adipose tissue (BAT) is one of the smallest organs in the body, it has the potential to have a substantial impact on both heat production as well as fat and carbohydrate metabolism. This is most apparent at birth which is characterised with the rapid appearance and activation of the BAT specific mitochondrial uncoupling protein (UCP)1 in many large mammals. The amount of brown fat then gradually declines with age, an adaptation that can be modulated by the thermal environment. Given the increased incidence of maternal obesity and its potential transmission to the mother's offspring, increasing BAT activity in the mother could be one mechanism to prevent this cycle...

This investigation studied the effects of different feed withdrawal times, water temperatures, and their interaction on growth performance, carcass traits, blood parameters, and health aspects of native turkeys (Egyptian local breed). We distributed native turkey poults (n = 180; 4 wk old) into 3 groups according to feed withdrawal time (ad libitum; feed withdrawal from 800 to 1,400 h, FW8 to 14; and feed withdrawal from 1,400 to 2,000 h, FW14 to 20). Each group was further divided into 2 subgroups corresponding to water temperature (ordinary and chilled water)...

BACKGROUND: Volatile anesthetics are increasingly used for sedation in intensive care units. The most common administration system is AnaConDa-100 mL (ACD-100; Sedana Medical, Uppsala, Sweden), which reflects volatile anesthetics in open ventilation circuits. AnaConDa-50 mL (ACD-50) is a new device with half the volumetric dead space. Carbon dioxide (CO2) can be retained with both devices. We therefore compared the CO2 elimination and isoflurane reflection efficiency of both devices. METHODS: A test lung constantly insufflated with CO2 was ventilated with a tidal volume of 500 mL at 10 breaths/min...

In this Research Communication we describe the effect of temperature and humidity index (THI) on various physiological traits, the plasma heat shock protein 70 (HSP70), heat shock protein 90 (HSP90) and cortisol levels and other blood parameters in crossbred buffalo (Nili-Ravi × Murrah) and Mediterranean buffalo to compare their tolerance to heat stress. As expected, crossbred buffalo had a significantly higher rectal temperature (RT), body surface temperature (BT), respiratory rate (RR), HSP70 and HSP90 levels in summer compared to spring and winter...

RATIONALE: Pain is the leading reason for seeking health care, and mu opioid receptor agonists continue to be prescribed despite well-documented adverse effects. Kappa opioid receptor agonists have antinociceptive effects with little to no abuse liability and might be useful for treating pain in mixtures. Kappa:mu opioid mixtures might be useful if therapeutic effects of each drug can be selectively increased while reducing or avoiding the adverse effects that occur with larger doses of each drug alone...

BACKGROUND: Melatonin has analgesic, anti-inflammatory, sedative, and anxiolytic properties. However, the relationship between endogenous melatonin levels and postoperative analgesic requirements has not been well elucidated in patients undergoing bariatric surgery. We studied endogenous melatonin levels, cortisol levels, body temperatures, and the relationship between the level of endogenous melatonin and postoperative morphine consumption. METHODS: The trial was conducted among 30 patients who were scheduled for laparoscopic bariatric surgery...

Solitary bees in seasonal environments must align their life-cycles with favorable environmental conditions and resources; the timing of their emergence is highly fitness relevant. In several bee species, overwintering temperature influences both emergence date and body weight at emergence. High variability in emergence dates among specimens overwintering at the same temperatures suggests that the timing of emergence also depends on individual body conditions. However, possible causes for this variability, such as individual differences in body size or weight, have been rarely studied...

In response to cold exposure, placental mammals maintain body temperature by increasing sympathetic nerve activity in brown adipose tissue (BAT). Triggering of β-adrenergic receptors on brown adipocytes stimulates thermogenesis via induction of the cAMP/PKA pathway. Although cAMP response element-binding protein (CREB) and its coactivators-the cAMP-regulated transcriptional coactivators (CRTCs)-mediate transcriptional effects of cAMP in most tissues, other transcription factors such as ATF2 appear critical for induction of thermogenic genes by cAMP in BAT...

BACKGROUND: Healthcare-associated infections (HAIs) caused by multidrug-resistant bacteria (MDRB) are of global concern and hospital textiles can contribute to their transmission. MDRB are able to survive on textiles for more than enough time to spread in the environment. Some studies summarized the effect of environmental factors on the duration of bacterial survival, but it remained an open question how these factors influence the quantity of surviving bacteria in a period of a few days, which is relevant from the perspective of HAIs...

Specific nucleic acids amplification at a constant and mild temperature is important for imaging assay of endogenous microRNAs (miRNAs) in living cells. Duplex-specific nuclease (DSN) is attractive in one-step isothermal assay of miRNA; however, its intrinsic limitations of low amplification specificity and high reaction temperature greatly restrict the application scope. Herein, we present a short-probe-based DSN signal amplification (spDSNSA) strategy enabling analysis of miRNAs at body temperature with significantly high specificity...

BACKGROUND: As an opportunistic pathogen, E. gallinarum mainly leads to nosocomial infections, and it's multi-drug resistance has gained more and more attention. Central nervous system infections caused by E. gallinarum are rare, but have been reported more often in recent years. The previous cases were generally secondary to neurosurgery, especially ventriculoperitoneal shunts. In recent years, the cases largely occurred in patients with impaired immune function. The patient in our report may have had dual risk factors (immune impairment and an invasive surgical procedure)...

James McLeod, Z Othman, Rajarathinam Parthasarathy
The relationship between mixing energy input and biogas production was investigated by anaerobically digesting sewage sludge in lab scale, hydraulically mixed, batch mode digesters at six different specific energy inputs. The goal was to identify how mixing energy influenced digestion performance at quantitative levels to help explain the varying results in other published works. The results showed that digester homogeneity was largely uninfluenced by energy input, whereas cumulative biogas production and solids destruction were...

Bathing is a routine care procedure that exposes preterm infants to prolonged handling, which could cause stress and potentially disrupt infants' biobehavioral responses. The aim of this double-blind randomized crossover trial was to compare the preterm infant's body temperature, heart rate (HR), peripheral capillary oxygen saturation (SpO2), salivary cortisol levels, and sleep-wake states during and after swaddled and conventional tub baths. Forty-three infants born at 32 to 36 weeks postmenstrual age, weighing 2225 g or less, were enrolled in the study...

Tattooing is a procedure where ink is applied to an area of the skin, mostly intraepidermally (1). This procedure is carried out mainly for aesthetic purposes. Lately, it has been used as a corrective medical procedure following amputation of mammilla. The procedure is aggressive (2), and the fact that skin is punctured many times with the same needle which cannot be fully sterilized may cause infection of the treated area with bacterial, fungal, or viral agents that may lead to health consequences manifesting in the form of verrucae vulgaris, molluscum contagiosum, and herpes simplex...

Stephen M Deban, Segall V Bloom
Miniaturization of body size is often accompanied by peculiarities in morphology that can have functional consequences. We examined the feeding behavior and morphology of the miniaturized plethodontid salamander Thorius, one of the smallest vertebrates, to determine if its performance and biomechanics differ from those of its larger relatives. High-speed imaging and dynamics analysis of feeding at a range of temperatures show that tongue projection in Thorius macdougalli is ballistic and achieves accelerations of up to 600 G with low thermal sensitivity, indicating that tongue projection is powered by an elastic-recoil mechanism...
