Assessment of Lumbar Intervertebral Disc Glycosaminoglycan Content by Gadolinium-Enhanced MRI before and after 21-Days of Head-Down-Tilt Bedrest
During spaceflight, it has been shown that intervertebral discs (IVDs) increase in height, causing elongation of the spine up to several centimeters. Astronauts frequently report dull lower back pain that is most likely of discogenic origin and may result from IVD expansion. It is unknown whether disc volume solely increases by water influx, or if the content of glycosaminoglycans also changes ...
متن کاملThe Health quality assessment patients whit Lumbar disc herniation, before and after Herniated Lumbar Disc surgery
Introduction and Aim: Lumbar disc herniation is one of the most common causes of low back pain. Sciatic pain in association with lumbar disc herniation may require surgical intervention in the form of lumbar discectomy.Chronic illnesses such as the low back pain has important consequences like an alteration in the health quality of the person. Health quality is a multi-faceted concept and goes ...

15 صفحه اولHemolysis during and after 21 days of head‐down‐tilt bed rest
Hemoconcentration is observed in bed rest studies, descent from altitude, and exposure to microgravity. Hemoconcentration triggers erythrocyte losses to subsequently normalize erythrocyte concentration. The mechanisms of erythrocyte loss may involve enhanced hemolysis, but has never been measured directly in bed rest studies. Steady-state hemolysis was evaluated by measuring two heme degradatio...
متن کاملLoss and re-adaptation of lumbar intervertebral disc water signal intensity after prolonged bedrest
The adaptation and re-adaptation process of the intervertebral disc (IVD) to prolonged bedrest is important for understanding IVD physiology and IVD herniations in astronauts. Little information is available on changes in IVD composition. In this study, 24 male subjects underwent 60-day bedrest and In/Out Phase magnetic resonance imaging sequences were performed to evaluate IVD shape and water ...
