Carcinus muscle fibers respond to gamma-aminobutyric acid (GABA) with a conductance increase that subsides rather rapidly. In the larger fibers which have low input resistance the decrease may disappear within 2 min. The inhibition of the excitatory postsynaptic potentials (EPSP's) by GABA nevertheless persists as long as the drug is applied. The subsidence of the increased conductance indicate...

We investigate the environmental impacts of several forms of policies that offer farmers subsides in return for adoption of conservation tillage. The policies differ on whether the tillage practice or one of the environmental benefits is targeted. We develop an environmental Lorenz curve that fully represents the performance of the targeting policies, and we show that these curves can be used d...

Its probable first account has been given by Plutarch in his comments on Alexander’s invasion of India: “Many then were the dangers— but the greatest harm came from severity of weathers”. Similarly, a Chinese record mentions of “Lesser Headache Mountains” and the “Greater Headache Mountains” where men’s bodies become feverish, they lose color and are attacked with headache, dizziness and vomiti...

We have demonstrated Laser speckle imaging of a finger with an optical configuration based on scattered light detection. Laser light enters a light-guide from its edge and propagates inside. A finger in contact with the light-guide scatters the light and the leaking light is imaged by a camera placed nearby. The speckle image fluctuates with time because the light scattered by the blood flowing...

We investigate the relationship between people who worked from home during pandemic and how often they walked before, during, after COVID. find that had largest increases in walking frequency compared to did not work were unemployed. Similarly, also expect walk more subsides others. After controlling for socio-economic, demographic, transportation factors, we found working having a high income ...

The case A 32-year-old male runner visits his family physician in late spring complaining of pain in his knees over the past month. The pain is mostly anterior but is not well localized. It is aggravated by...

i) Pain occurs at rest; 2) the discomfort is not related to physical activity or emotional stress; 3) generally, it is longer in duration and more severe; 4) instead of ST segment depression, typical of classic angina, the electrocardiogram shows a transient acute monophasic injury current with reciprocal changes in the standard leads. The ST segment elevation subsides when the pain disappears....

A few months ago, my fiancé and I, after much consideration, decided to stop using condoms and rely only on the Pill as a contraceptive method. Since then, when he ejaculates inside my vagina, I frequently experience a strong burning sensation a few minutes afterward ? varying in both degree and length each time. Could I be allergic to his semen? The pain sometimes subsides if I hold a wet clot...

Appendicitis is not the only common cause of acute abdominal pain in childhood. Almost equally common is an acute episode which in its early stages resembles acute appendicitis but which subsides without treatment in 24 to 48 hours. The clinical features of this syndrome are contrasted with those of appendicitis. The two conditions cannot always be distinguished on clinical grounds, leading to ...
