The increased use of donor epithelium in keratoplasty for severe corneal disease has prompted an investigation of epithelial viability during midterm storage. Glycogen, ATP, and ADP have been used as indicators of the metabolic state of epithelial cells. These substances have been measured after conventional moist-chamber storage at 4 degrees C. for 1, 2, and 12 days and after immersion at 4 de...

ERYTHROMELALGIA is a rare syndrome characterized by episodic burning pain, erythema, and elevated temperature of the feet, hands, or both.[1,2] The syndrome can occur alone or with myeloproliferative or other diseases.[3-5] Attacks may last from minutes to days and can persist indefinitely in the absence of treatment. The pathophysiology of erythromelalgia is poorly understood. Case reports in ...

Over the past decades, plant cryopreservation technologies have been evolving rapidly, opening the door to the possibility of long-term storage of valuable genetic resources of many crop and forest species. From the original slow-cooling approach, research has moved to easier and more reproducible techniques which allow a complete vitrification of extraand intra-cellular liquids through the dir...

The purpose of this study was to investigate the effects of muscle temperature and fatigue during stretch (eccentric) and shortening (concentric) contractions of the maximally electrically activated human adductor pollicis muscle. After immersion of the lower arm in water baths of four different temperatures, the calculated muscle temperatures were 36.8, 31.6, 26.6, and 22.3 degrees C. Normaliz...

EVIDENCE of vasoconstriction in remote skin areas in response to local application of cold has been reported by various investigators.t-6 Pickering7 studied this respouse thoroughly; he showed that immersion of one hand and forearm in cold water produced a transient vasoconstriction of the opposite hand. Two modes of action are probably involved in the reflex vasoconstrictor response to cooling...

Bamboo is a natural material having a fast reproduction and high mechanical strengths. However, when a bio-based material in general, and bamboo in particular are expected to be a construction material, their sensitivity to moisture and their durability are usually questionable. Indeed, it is well known that these materials do not possess the same performance in the long-term, when compared to ...

A 2-gram fresh weight inoculum of bromegrass (Bromus inermis Leyss. culture BG970) cell suspension culture treated with 7.5 x 10(-5) molar abscisic acid (ABA) for 7 days at 25 degrees C survived slow cooling to -60 degrees C. Over 80% of the cells in ABA treated cultures survived immersion in liquid N(2) after slow cooling to -40 or -60 degrees C. In contrast, a 6-gram fresh weight inoculum onl...

We report on low-temperature noise measurements of a single electron transistor (SET) immersed in superfluid 4He. The device acts as charge sensitive electrometer able to detect the fluctuations charged defects close proximity SET. In particular, we measure telegraph switching electric current through originating from strongly coupled individual two-level fluctuator. By embedding helium immersi...
