The patterns of feed intake when animals are allowed ad libitum access to feed in a respiration chamber is not known, nor are the potential effects of the artificial environment of chambers on voluntary feed intake. The objectives of the study were to describe the pattern of hourly feed intake of sheep when fed for ad libitum intake in respiration chambers and determine the repeatability of thi...

The effect of methylglyoxal on the oxygen consumption of Ehrlich-ascites-carcinoma (EAC)-cell mitochondria was tested by using different respiratory substrates, electron donors at different segments of the mitochondrial respiratory chain and site-specific inhibitors to identify the specific respiratory complex which might be involved in the inhibitory effect of methylglyoxal on the oxygen consu...

Experimental studies have indicated that compounds such as 4,4'-dihydroxy-a,f-diethylstilbene, commonly referred to as stilbestrol, greatly influence the physiological processes of animals and microorganisms. Brownlee et al. (1943) demonstrated that stilbestrol-type compounds were bactericidal against the gram-positive staphylococci and streptococci. Shacter (1953a) reported that stilbestrol fi...

Tiiiv interesting letter from Dr. Rajandra Prasad on the above subject in the May number of the Indian Mcdical Gazette was found by nic a very opportune one, as similar cases occurred in Bulsar. On 16th June, 1929, in the afternoon I was sent for to render artificial respiration to 3 patients. The history was as follows:?A rice mill had a disused well in its compound, which for some reason or o...

In commenting on these experiments one should point out that the artificial respiration experiments wefe carried out with a technic which surely resulted in alkalosis due to actual hyperventilation. This impression is confirmed in the authors' footnote which states that glass electrode determinations in subsequent experiments indicated that the pH of the brain tissue was shifted toward the alka...

The effect of methylglyoxal on the oxygen consumption of mitochondria of both normal and leukaemic leucocytes was tested by using different respiratory substrates and complex specific artificial electron donors and inhibitors. The results indicate that methylglyoxal strongly inhibits mitochondrial respiration in leukaemic leucocytes, whereas, at a much higher concentration, methylglyoxal fails ...

Understanding the response mechanisms of litter respiration to soil moisture in water-limited semi-arid regions is of vital importance to better understanding the interplay between ecological processes and the local carbon cycle. In situ soil respiration was monitored during 2010-2012 under various conditions (normal litter, no litter, and double litter treatments) in a 30-year-old artificial b...
