Home and away: allometry and climate drive morphology of European rabbits in their native and introduced range

Oikos, EarlyView.
Climatic conditions shape phenotypic evolution by driving adaptations that optimise organismal function. Invasive species provide valuable systems to study these processes, as they often encounter novel climatic conditions in their introduced ranges. The European rabbit Oryctolagus cuniculus, native to the Iberian Peninsula, has established populations

Protection of the brain against heat damage

Journal of Physical Fitness and Sports Medicine, 2014
In homeothermic animals, metabolic heat production in the brain is higher than in other tissues. However, cerebral tissue is susceptible to heat. Several animals have mechanisms that selectively cool the brain during hyperthermia (i.e., selective brain ...

Re-visiting the tympanic membrane vicinity as core body temperature measurement site. [PDF]

PLoS ONE, 2017
Core body temperature (CBT) is an important and commonly used indicator of human health and endurance performance. A rise in baseline CBT can be attributed to an onset of flu, infection or even thermoregulatory failure when it becomes excessive.

An Experimental Study on the Protective Effect of Memantine in Noise‐Induced Hearing Loss

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Objective This study examined the potential protective effects of memantine, an N‐methyl‐D‐aspartate (NMDA) receptor antagonist, against acoustic trauma (AT) in guinea pigs, using electrophysiological and histopathological analyses. Methods Thirty guinea pigs with normal hearing were divided into six groups (n = 5 per group): Group 1 (control),

Body Temperature using Oral Mercury Thermometer in Comparison to Infrared Tympanic Thermometer

مجله دانشکده پزشکی اصفهان, 2011
Background: Standard method for measuring body temperature has relied on oral site by using mercury thermometers (MT). Infrared tympanic thermometry (ITT), which measures the flow of heat from the surface of tympanic membranes and ear canal, is ...

Há equivalência entre a temperatura da membrana timpânica e a temperatura retal em ovinos Santa Inês normotérmicos? Is there equivalence between the tympanic membrane temperature and the rectal temperature in normothermic Santa Ines sheep?

Ciência Rural, 2008
A utilização do termômetro de raios infravermelhos para a aferição da temperatura timpânica em animais tem se tornado uma alternativa prática na clínica veterinária. Em ovinos, a mensuração da temperatura timpânica não foi suficientemente comparada com a

The Effect of Light Intensity on Blood Pressure, Heart Pulse Rate, Blood Oxygen Saturation and Temperature of Children in Jenin-City Schools [PDF]

مجلة جامعة النجاح للأبحاث العلوم الطبيعية, 2014
The study population consisted of 237 children aged 5-6 years in Jenin city. The arterial blood pressure (systolic and diastolic), heart pulse rate, oxygen saturation in blood and tympanic temperature were measured before and after exposure to light ...

A Tympanic Membrane Temperature Measurement Technique for Birds

Poultry Science, 1974
Abstract Since the reliability of rectal temperature as a true indicator of rapid changes in body temperature has been questioned, the tympanic membrane has been proposed to be a more appropriate site for temperature measurement. The tympanic membrane is relatively close to the hypothalamus which is considered to be the location of the ...

Safety pharmacology of acute mescaline administration in healthy participants

British Journal of Clinical Pharmacology, EarlyView.
Aims Psychedelics, including mescaline, may serve as novel treatments for depression and anxiety. However, data is scarce on the safety of mescaline. Methods The present pooled analysis included two double‐blind, randomized, placebo‐controlled studies with a total of 48 participants and 96 mescaline administrations. Single oral‐dose administrations (n =

Peripheral Inflammation and Sleep Loss Induce Coordinated Motivational Changes: An Experimental Two‐Hit Stress Model

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep loss and low‐grade inflammation are common stressors that affect behaviour and recovery needs. To examine their separate and combined effects on motivation for everyday behaviours, we developed a two‐hit experimental model. Participants (N = 56, 31 women) completed three experimental visits: sleep saturation (two nights, 9 h in bed/night)
