Inter-troop transfer of Lemur catta males at Berenty, Madagascar.

Lemur catta male exchange occurred throughout the reserve at Berenty and affected change in the composition of most, if not all, of the twelve troops in the reserve. Males migrate into troops with which they are already familiar. Inter-troop encounters may serve to increase a male's knowledge of a potential new home. Extensive overlap in home ranges may facilitate this process. An important result of migration in L. catta is the avoidance of inbreeding in a species whose females form stable groups over long periods of time and do not breed out of their troop.

Similarities between gibberellins and related compounds in inducing Acid phosphatase and reducing sugar release from barley endosperm.

Barley endosperm halves release acid phosphatase in response to several gibberellins and gibberellin precursors. Seed halves incubated with 10(-7)m GA(3) at 29 degrees begin to release phosphatase after 11 hr and release it for another 26 hr in response to GA(3). After 37 hr, the rate of release slows to that of seed halves incubated without GA(3). GA(3) is active at 10(-10)m and maximally active at 10(-7)m. Comparative activity of 12 gibberellins and gibberellin precursors is GA(1) = GA(3) > GA(2) > GA(4) = GA(7) > GA(5) = GA(13) > GA(14) > GA(8) = GA(9) > (-)kaurenoic acid > (-)-kaurene. These compounds show the same order of activity and approximately the same relative activity in inducing reducing sugar release as in inducing phosphatase activity. The activity of each compound increases with its presumed position in a biosynthetic pathway leading from kaurene to GA(3). This correlation suggests that activity may be a reflection of the efficiency of conversion to an active form within the seed half.The ease of measuring the acid phosphatase response and the sensitivity of the seed halves to low concentrations of many gibberellins and gibberellin precursors makes this a useful bioassay for gibberellin-like substances.

Molten metal burn of the foot: a preventable injury.

Molten metal burns of the feet remain a common injury to foundry workers. A case is reported of a foundry worker who sustained circumferential molten metal burns of the distal foot and toes necessitating amputation of four toes. This severe injury could easily have been prevented by the use of protective footwear and spats.

A disposable emergency wound treatment kit.

Biomechanical studies in our laboratory have provided a scientific basis for selecting surgical gloves and instruments, drugs, and dressings for traumatic wound treatment. This armamentarium has been incorporated into a disposable emergency wound treatment kit for use in the emergency department. Its upper tray is for wound cleansing, while its lower tray is used for wound closure. A clinical evaluation of the kit by emergency physicians was very favorable because it saved time, eliminating the need to search for and assemble the gloves, instruments, drugs, and dressings for wound treatment.

Scavenging high-voltage copper wire, a hazardous petty larceny.

With the current emphasis on recycling and the establishment of markets for sale of used copper wire, scavenging of copper wire from old buildings and equipment has become common. Although scavenging without permission constitutes theft, a more significant risk to the perpetrator is the potential for electrical burn injury in attempting to remove "hot" wire. A severe high-voltage electrical burn injury sustained while attempting to scavenge wire from an old house is reported. The circumstances surrounding the injury, the clinical management of the case, and the long-term consequences to the patient are presented and discussed.

Maintaining infusion therapy services in the long-term care setting.

The volume of infusion therapy services provided in the long-term care setting has declined. One major influence has been the changes in reimbursement experienced in this sector of the industry. This article is intended to stimulate the long-term care clinician to reexamine the service offered and to be creative in his or her approach to building infusion services. The article also explores parallels to the home infusion industry, which has evolved through similar changes, with the intent of learning from its experiences.
