The contractile properties of the triceps surae (medial and lateral gastrocnemii and soleus) have been studied in humans. In comparison with most other human muscles, the triceps complex had a slow twitch (mean contraction and half-relaxation times 112.4 +/- 11.

First, the free-text input is parsed and the information is arranged in a tabular format by a general-purpose natural language processor developed at New York University.

In all normal tissues and blood cells studied except leukocytes we found less than 0.1% (expressed as micrograms per gram of wet weight of tissue) of the quantity of immunoreactive prostatic acid phosphatase detected in normal prostate tissue by radioimmunoassay.

A method is described for investigating the contractile properties of the dorsiflexor muscles of the ankle. With the joint in the midposition the tibialis anterior was found to contribute less than half of the maximum voluntary torque, the remainder presumably being provided by the long extensors of the toes. The mean contraction and half-relaxation times of tibialis anterior muscles in healthy young men were 81.

A flow-rate dependent increase in the growth rate was observed both by 3H-thymidine uptake and by a rise in cell numbers. The characteristics of the response were dependent on the recirculating volume and on whether serum was present in the culture medium.

Following unilateral superior cervical ganglionectomy, denervated salivary gland contained 24% less (p less than 0.02) radioimmunoassayable T3/mg and took up 20% less (p less than 0.

Two R factors which have the capacity to improve survival of some strains of Escherichia coli K-12 by approximately 60% after ultraviolet light have been identified and characterized. Both are fi(-), but neither produce colicins. The ability to enhance survival can be separated from all other identified R-factor functions.
