Nasopulmonary bronchomotor reflexes elicited by mechanical or irritant stimulation of the nose have been described in animals and asthmatic patients. However, few studies were devoted to the consequences of nasal breathing of cold and dry air or of only dry or only moist air on the bronchomotor control in normal individuals. The present study reported changes in interruption resistance (Rint) m...

The cold weather is associated with an increased occurrence of acute coronary events. However, the mechanisms underlying cold‑induced myocardial infarctions have not yet been fully elucidated. In the present study, 20 male, eight week‑old, apolipoprotein E (ApoE)‑deficient mice were subjected to either control conditions or intermittent cold exposure for eight weeks. Mice in the cold group were...

I t has recently been shown that freshly prepared rat liver mitochondria contain a distinct and constant complement of various acid-soluble nucleotides (1). Similar extracts of rat liver microsomes exhibit an entirely different picture, containing in measurable amounts only the nudeoside, inosine. In some recent studies young, Sprague-Dawley rats, obtained from the Holtzman Rat Co., Madison, Wi...

BACKGROUND Storing platelets for transfusion at room temperature increases the risk of microbial infection and decreases platelet functionality, leading to out-date discard rates of up to 20%. Cold storage may be a better alternative, but this treatment leads to rapid platelet clearance after transfusion, initiated by changes in glycoprotein Ibα, the receptor for von Willebrand factor. DESIGN...

The study reports the mechanical property and microstructure of cold rolled low carbon steel and its work-hardening behavior in the deformation process. The tensile test in room temperature of low carbon steel was implemented for the different cold rolling deformation, the stress-strain curve was draught according to the relationship between strength and deformation and fitted for the polynomia...

Thyroid function decreases and cold exposure response becomes impaired with increasing age. We investigated the age-related changes in thyroid structure and function and cold-induced changes in the thyroid activity of aging rats. Thirty-two male Sprague-Dawley rats were randomly divided into four groups (8 rats per group): young (7 months) and old (22 months) groups exposed to room temperature ...

Citrated platelet-rich plasma (PAP) was kept at cold temperatures or room temperature. After 4 hr or more at these temperatures, the PRPs were warmed 1 hr at 37#{176}C. This prevents the spontaneous aggregation seen in chilled PRP that is stirred immediately after warming. Platelet aggregation in response to connective tissue (CT), epinephrine, and adenosine diphosphate (ADP) was considerably g...

Fermi-Dirac electron thermal excitation is an intrinsic phenomenon that limits functionality of various electron systems. Efforts to manipulate electron thermal excitation have been successful when the entire system is cooled to cryogenic temperatures, typically <1 K. Here we show that electron thermal excitation can be effectively suppressed at room temperature, and energy-suppressed electrons...

Cold urticaria is one of the least common types of urticaria, affecting approximately 1% to 3% of all patients with urticaria [1]. Patients present generalized or local wheal lesions in areas that come into contact with cold stimuli such as cold air, water, or objects. The symptoms may or may not be accompanied by angioedema. Cold urticaria can be primary or associated with other pathologies su...
