Threaded connectors (Figure 40.34) are made with standard pipe threads cut on the inside surface (female). The end of the pipe is threaded with outside threads (male). Standard pipe threads are tapered slightly to ensure tight connections. The amount of taper is approximately inch in diameter per foot of thread. 

Uniformly labeled C-8-D with a specific activity of 2.99 juc/mg was administered orally to pregnant females at 2 /xg/kg/day from 6-15 days of gestation. Three females were sacrificed on alternate days during days 6-20 of pregnancy. Triplicate samples of fetus, placenta, blood, brain, abdominal fat, and sartorius muscle were procured from each female. The samples were dissolved in 1 ml of Soluene (Packard Instruments) to which 15 ml of Aquasol were added. Each sample vial was counted for 30 min in a Nuclear Chicago Mark I liquid scintillation counter. 

In healthy individuals, the bladder, ureters and urethra are sterile and sterile urine constantly flushes the urinary traet. Organisms invading the urinary traet must avoid being detached Ifom the epithelial surfaces and washed out during urination. In the male, since the urethra is long ica. 20 cm), bacteria must be introduced directly into the bladder, possibly through eatheterization. In the female, the urethra is much shorter... 

Sexually differentiated responses to female-soiled bedding occur within the regions of the AOB only the rostral zone was -activated in males as opposed to that of females the caudal zone cells had no such differential activation VN-x removed the response (Dudley and Moss, 1999 Matsuoka et al., 1999). The number of Fos-ii cells was larger after exposure to females of ICR stain, than to BALB females. Male strain-differences gave equivalent amounts of rostral/caudal activity in females. It is probable that discrimination by females of between-strain chemosignals is related to the fine distinctions possible through the operation of cues related to influence of products from the MHC loci. 

A sex difference in the rate of conversion of DIMP to its primary metabolite was observed after intravenous administration of 14C-DIMP in rats (Bucci et al. 1992). The males appeared to convert DIMP to IMPA more actively than the females. The apparent plasma elimination half-life of DIMP was about 45 minutes in males and up to 250 minutes in females. Both the rate and total excretion of the administered dose in urine were also higher in male rats. However, this sex difference was not observed for orally-administered DIMP in minks (Bucci et al. 1992 Weiss et al. 1994). 

In rats given 66 or 660 mg/kg diisopropyl methylphosphonate, peak radioactivity in the blood was at 2-3 hours in both sexes at both doses however, radioactivity was still detectable in the blood 24 hours postadministration in the 66-mg/kg group (Weiss et al. 1994). After intravenous administration of 66 mg/kg, the elimination half-life of diisopropyl methylphosphonate was estimated at 45 minutes in males and 250 minutes in females the rate of excretion was greater in males than in females. Urine and feces together accounted for 86-97% of administered radioactivity in males and 57-62% in females. 

The term percent means the quantity or number of units out of one hundred units total. Percentage is computed by finding the fraction of the total quantity represented by the quantity under discussion, and multiplying by 100%. For example, if a group of 12 persons includes 9 females, the percent females in the group is... 

Dissected adult female the parasite has been cut longitudinally and the gut and reproductive organs removed to form the characteristic muscle flap . (C) Vesicles forming from a muscle cell after treatment with collagenase the vesicles are then transferred to the experimental chamber, where vesicle-attached patches are formed and single-channel recordings made. 

Volatiles and cuticular extracts from both sexes of the currant stem girdler, Janus integer, were analyzed by GC-EAD using antenna ofboth sexes. A female specific compound, (9Z)-octadec-9-en-4-olide 7, was identified as active only on male antennas [33]. Separation by chiral GC has shown that only one enantiomer is produced in females. The synthesis ofboth enantiomers has recently been described [34] and the field testing results are forthcoming. 

Singhasivanon et al. [131] investigated the pharmacokinetics of primaquine in eight healthy subjects (four males and four females). The volunteers received 15 mg base of primaquine daily for 14 days. The results showed that the concentrationtime profiles in whole blood and in plasma were similar. The mean values ( SD) of the area under the curve of the last dose were significantly decreased when compared to the values of the first dose both in the whole blood and in plasma. 

In females, the short length of the urethra and proximity to the perirectal area make colonization of the urethra likely. Bacteria are then believed to enter the bladder from the urethra. Once in the bladder, the organisms multiply quickly and can ascend the ureters to the kidney. 

Our work clearly demonstrates that the main as opposed to the accessory olfactory system plays a central role in mate recognition in both male and female mice. By contrast, clear sex differences emerge in the relative roles of these two olfactory systems in the regulation of mating. Thus, the main olfactory system seems to be more important in regulating sexual behavior in the male, whereas in the female, the accessory olfactory system seems to predominate. 

The arrangement remains puzzling, but the bees easily resolve the problem (or what we see as a problem). When the parasitic bees mate, the male simply sprays some of his F6 on the female. The compound is relatively involatile and so persists on the gravid female as she seeks host nests for her eggs. Perfumed with F6 from her mate, the parasitic female penetrates the host nest and completes her task unchallenged. At least three other species of parasitic Nomada bees gain acceptance by their Andrena hosts in this way.
