Study on the effect of a cold environment on the quality of three video laryngoscopes: McGrath MAC, GlideScope Ranger, and Pentax Airway Scope [PDF]

open access: yesClinical and Experimental Emergency Medicine, 2019
Objective Several environmental factors influence the prehospital use of video laryngoscopes (VLs). For example, fogging of the VL lens can occur in cold environments, and the low temperature can cause the VLs to malfunction.

Thermal compensator for closed-cycle helium refrigerator [PDF]

open access: yes, 1979
The wave length of an infrared, semiconductor laser diode having an output frequency that is dependent on the diode temperature is maintained substantially constant by maintaining the diode temperature constant.

Universal Minimum Heat Leak on Low-Temperature Metallic Electrical Leads

open access: yes, 2006
Low-temperature electronic systems require electrical leads which have low electrical resistance to provide bias current I without excessive voltage drop V. But proper cryogenic design also requires high thermal resistance to maintain a minimum heat leak

The Role of Cold Flows in the Assembly of Galaxy Disks [PDF]

open access: yes, 2008
We use high resolution cosmological hydrodynamical simulations to demonstrate that cold flow gas accretion, particularly along filaments, modifies the standard picture of gas accretion and cooling onto galaxy disks.

Aberrant expression of nuclear prothymosin α contributes to epithelial‐mesenchymal transition in lung cancer

open access: yesMolecular Oncology, EarlyView.
Nuclear prothymosin α inhibits epithelial‐mesenchymal transition (EMT) in lung cancer by increasing Smad7 acetylation and competing with Smad2 for binding to SNAI1, TWIST1, and ZEB1 promoters. In early‐stage cancer, ProT suppresses TGF‐β‐induced EMT, while its loss in the nucleus in late‐stage cancer leads to enhanced EMT and poor prognosis.

Qualitative identification and characterisation of self-reported symptoms arising in humans during experimental exposure to cold air

open access: yesInternational Journal of Circumpolar Health, 2019
Background: Exposure to cold air is associated with increased morbidity and mortality in the general population. It is difficult to study the effects of whole-body exposure to cold air under controlled conditions in real life. Objectives: The aim of this

The effect of ambient temperature on cold start urban traffic emissions for a real world SI car [PDF]

open access: yes, 2005
The influence of ambient temperature on exhaust emissions for an instrumented Euro 1 SI car was determined. A real world test cycle was used, based on an urban drive cycle that was similar to the ECE urban drive cycle.

Murder or Not? Cold Temperature Makes Criminals Appear to Be Cold-Blooded and Warm Temperature to Be Hot-Headed

open access: yesPLoS ONE, 2014
Temperature-related words such as cold-blooded and hot-headed can be used to describe criminal behavior. Words associated with coldness describe premeditated behavior and words associated with heat describe impulsive behavior. Building on recent research about the close interplay between physical and interpersonal coldness and warmth, we examined in a ...

TRPM8 levels determine tumor vulnerability to channel agonists

open access: yesMolecular Oncology, EarlyView.
TRPM8 is a Ca2+ permissive channel. Regardless of the amount of its transcript, high levels of TRPM8 protein mark different tumors, including prostate, breast, colorectal, and lung carcinomas. Targeting TRPM8 with channel agonists stimulates inward calcium currents followed by emptying of cytosolic Ca2+ stores in cancer cells.

Decrease of Environmental Temperature May Trigger the Onset of Acute Aortic Dissection

open access: yesSoutheastern European Medical Journal, 2020
Aim: The most important risk factors for a Stanford type A acute aortic dissection (AAD) include arterial hypertension and connective tissue disorders, while numerous studies have identified meteorology factors, such as environmental temperature also ...
