Neuropathy in female dental personnel exposed to high frequency vibrations

Objective-To evaluate early neuropathy in dental personnel exposed to high frequency vibrations. Methods-30 dentists and 30 dental hygienists who used low and high speed hand pieces and ultrasonic scalers were studied, and 30 dental assistants and 30 medical nurses not exposed to vibration (all women). Vibrotactile sensibility, strength, motor performance, sensorineural symptoms and signs, and vas

Plasma C3d levels of young farmers correlate with respirable dust exposure levels during normal work in swine confinement buildings

Work in swine confinement buildings leads to an inflammatory response and may be associated with increased levels of acute phase proteins. We compared the inflammatory response of a control group of young former farm workers with age-matched former farm workers who had previously developed the lower airway symptoms of wheeze, cough, tightness of the chest during work in swine confinement buildings

Studies on chondrocyte integrins and mechanical signaling

Popular Abstract in Swedish Brosk är en typ av vävnad som finns på många olika ställen i vår kropp. Karakteristiskt för brosk är att det är mycket hållfast samtidigt som det medger en hög grad av flexibilitet. Ledbrosket är det tunna brosklager som klär kortändarna på benen i skelettet. Dess uppgift i leden är att fungera som stötdämpare för att skydda det underliggande benet samt att utgöra den gIntegrins are a family of cell surface receptors known to bind matrix proteins and to mediate signals such as mechanical signals between the cell and the surrounding matrix. We have studied integrins that are expressed by chondrocytes, with specific focus on the integrins that interact with the cartilage matrix protein collagen type II. It was found that chondrocytes isolated from articular cartil

Structural and physicochemical studies on metal and porphyrin binding by the Bacillus subtilis ferrochelatase

The enzyme ferrochelatase (EC 4.99.1.1) is the terminal enzyme in the biosynthetic pathway of heme b and catalyzes the insertion of Fe(II) into protoporphyrin IX. In this dissertation ferrochelatase from Bacillus subtilis was studied. A new purification method via inclusion bodies was developed that enabled simple purification of recombinant enzyme without tags or modifications that might affect t
