13. Reproductive behavior and sex pheromone identification of Pseudaletia sequax (Lepidoptera: Noctuidae) / Comportamento reprodutivo e identificação de feromônio sexual de Pseudaletia sequax (Lepidoptera: Noctuidae)
The effects of pupal period and age on calling behavior of virgin females of Pseudaletia sequax were determined. Larvae were reared on artificial diet. Calling behavior of groups of females of similar age of pupation was observed every 10 minutes for six days at reversed photoperiod. Females were considered calling when they had assumed a characteristic posi

14. Clinical and morphophisiological aspects of the rat knee articulation after immobilization and remobilization / Aspectos clínicos e morfofisiológicos da articulação fêmorotibio-patelar de ratos após imobilização prolongada e remobilização
The aim of this study was to evaluate the clinical and morphophisiological aspects of the rat knee articulation after immobilization and remobilization with free activity and swimming. Thirty four adult male rats (Wistar) were randomly allocated into one of four groups: without immobilization, (G1, n = 4), with immobilization (G2, n = 10), immobilization and

15. O Efeito de um protocolo de alongamento muscular passivo sobre a cartilagem articular.
Objective: The aim of this study is to evaluate the articular cartilage alterations of rat ankles, after applying unilateral cyclic passive muscle stretching protocol for three weeks in previously immobilized rats. Materials and Methods: Twenty-two male albino rats (280+25.4g) divided into four groups: I-immobilized (n=6), IS-immobilized and stretched (n=5),

16. Trp-cage: Folding free energy landscape in explicit water
Trp-cage is a 20-residue miniprotein, which is believed to be the fastest folder known so far. In this study, the folding free energy landscape of Trp-cage has been explored in explicit solvent by using an OPLSAA force field with periodic boundary condition. A highly parallel replica exchange molecular dynamics method is used for the conformation space sampl

17. Medical Applications of Dust-free Rooms. III. Use in an Animal Care Laboratory
Bacterial air sampling in an animal care laboratory showed that dense aerosols are generated during cage changing and cage cleaning. Reyniers and Andersen sampling showed that the airborne bacteria numbered 50 to 200 colony-forming units (CFU)/ft3 of air. Of the viable particles collected by Andersen samplers, 78.5% were larger than 5.5 μm. A low velocity l

18. Accumulation of Deleterious Genes in a Cage Population of DROSOPHILA MELANOGASTER
Lethal and sterility mutations were accumulated in a cage population which was initiated with lethal- and sterility-free second chromosomes of D. melanogaster. It took about 2,000 days for the frequencies of these genes to reach equilibrium levels, i.e., 18% lethal and 9% male-sterile chromosomes. Two other cage populations which were initiated with random

19. Norfloxacin penetration into subcutaneous tissue cage fluid in rabbits and efficacy in vivo.
The activity of norfloxacin was studied in vivo with steel net cages implanted subcutaneously in rabbits. Four weeks after implantation, two of four cages in each animal were inoculated with a strain of Escherichia coli (seven animals) or Klebsiella pneumoniae (six animals). Four animals in each group received oral treatment with norfloxacin for 7 days. Trea

20. New Ventilated Isolation Cage
A multifunction lid has been developed for a commercially available transparent animal cage which permits feeding, watering, viewing, long-term holding, and local transport of laboratory rodents on experiment while isolating the surrounding environment. The cage is airtight except for its inlet and exhaust high-efficiency particulate air filters, and it is c

21. Mapping sequences in loops of nuclear DNA by their progressive detachment from the nuclear cage.
Nuclear DNA is organised into loops, probably by attachment to a supramolecular structure. We describe a method which enables us to map the position of sequences within a loop relative to the point of attachment. Nuclear DNA is isolated unbroken by lysing HeLa cells in 2M NaCl to release structures which retain many of the morphological features of nuclei. T

22. Total prosthetic replacement of atrioventricular valves in the dog: Part II. Development of tilting cone mitral prosthesis
The free-floating cone and cage valve, described in a previous study as being successful as a substitute for the right atrioventricular valve, does not perform well when it is inserted in the mitral ostium. A tilting cone or disc was constructed and tested in a series of 15 dogs. This prosthesis gave excellent results in 12 animals. The reasons for its failu

23. How protein thermodynamics and folding mechanisms are altered by the chaperonin cage: Molecular simulations
How the Escherichia coli GroEL/ES chaperonin assists folding of a substrate protein remains to be uncovered. Recently, it was suggested that confinement into the chaperonin cage itself can significantly accelerate folding of a substrate. Performing comprehensive molecular simulations of eight proteins confined into various sizes L of chaperonin-like cage, we

24. Possible involvement of prostaglandins in psychological stress-induced responses in rats.
1. We investigated the effect of pre-treatment with intraperitoneal (I.P.) injection of indomethacin, an inhibitor of prostaglandin synthesis, on psychological stress-induced responses including cardiovascular, thermoregulatory and hormonal responses in free-moving rats. 2. Psychological stress was induced by cage-switch stress. After the rats were placed in
