Relationship between postural balance and knee and toe muscle power in young women.

Muscle power in the lower extremities and body sway were measured in 57 healthy young women volunteers in their 20's. Body sway was measured with a stabilimeter for 30 sec during two-leg standing, and for 10 sec during one-leg standing with the eyes open or closed, alternating between right and left legs (5 times each). The measured parameters of body sway were locus length per time unit, locus length per environmental area, environmental area, rectangle area, root mean square area, and the ratio of sway with eyes closed to sway with eyes open. Knee flexor and extensor power and toe flexor and abductor power were the measures representing lower extremity muscle power. The increase in sway with the eyes closed was more marked during one-leg standing than two-leg standing, as expected. We found that 36 of 57 subjects (62%) were unable to maintain one-leg standing with their eyes closed, and this failure correlated with marked body sway (P = 0.0086). Many subjects had one leg that was classified as stable and the other leg classified as unstable. Clearly, testing of both legs alternately with eyes closed is necessary to measure the full range of sway in subjects. Lower extremity muscle power did not appear to be the dominant factor in maintaining balance in these young subjects.</p

The effect of service dogs on the improvement of health-related quality of life

To assess the effects of service dogs on health-related quality of life (HRQOL), we conducted a survey of 10 service dog owners using SF-36v2 (Medical Outcomes Study 36 Item Short-Form Health Survey Version 2.0) and compared it with a matched control group of people with physical disabilities who did not have service dogs but were eligible for one. The scores for mental health and role emotional of service dog owners were relatively high, and their mental component summary was higher than the general population norm. These results indicate that service dogs affect the mentality of their owners. The comparison with the control group indicated that service dogs alleviate the mental burden of daily activities, and subjectively improved the physical functioning of their owners. This study showed that service dogs have positive functional and mental effects on their disabled owners.</p

Evi1 is essential for hematopoietic stem cell self-renewal, and its expression marks hematopoietic cells with long-term multilineage repopulating activity

A new mouse in which an IRES-GFP cassette is knocked-in to the Evi1 locus reveals that HSC long-term multilineage repopulating activity specifically segregates with expression of the Evi1 transcription factor

Einfluss des Fleischextraktes auf den Kohlehydratstoffwechsel

Verfasser hat den Einfluss des Extraktes von Rindfleisch auf den Kohlehydratstoffwechsel im Kaninchenorganismus studiert und folgendes gefunden: 1. Der rohe, schwach saure Extrakt hat bei peroraler Zufuhr eine starke hyperglykamische Wirkung, die entweder durch Abstumpfung der Reaktion oder durch Alkalisierung der Reaktion etwas abgeschwacht, aber durch Entfettung des Extraktes im Gegenteil etwas verstarkt gefunden wurde. 2. Diese hyperglykämische Wirkung des Fleischextraktes trat 1/2-1 Stunde nach seiner Verabreichung auf und dauerte 4-5 Stunden lang an, um dann zum normalen Wert zurückzukehren. 3. Durch Fütterung von entfettetem und enteiweisstem Extrakt wurde der Blutzuckergehalt herabgesetzt. Diese hypoglykämische Wirkung trat 4 Stunden nach der Zufuhr von Extrakt am stärksten auf. 4. Die hypoglykämische Wirkung der Cholsäure ist mit der des entfetteten und enteiweissten Extraktes synergisch. 5. Der entfettete und enteiweisste Extrakt zeigte auch bei Entfernung der Purinbasen eine hypoglykämische Wirkung, was höchstwahrscheinlich auf der Wirkung einer Kreatin im Extrakt beruhen durfte. 6. Die hyperglykämische Wirkung des rohen Fleischextraktes konnte durch Mitzufuhr von Phosphatpuffer fast oder ganz aufgehoben werden
