It has long been suggested that serotonin (5-HT) neurotransmitter system activity is associated with ethanol (ETOH) intake and dependence. The authors studied the effects of neonatal 5,7-dihydroxytryptamine (5,7-DHT) lesions on voluntary alcohol drinking in adult Wistar rats. At 3 days after birth animals were pretreated with desipramine (DMI) and then given a bilateral injection of 5,7-DHT int...

Testosterone and 5 alpha-dihydrotestosterone (DHT) concentrations in tissue and body fluid were determined in adult male rats to investigate the mode of androgen distribution. The highest concentration of androgen (testosterone + DHT) and the smallest ratio of DHT/testosterone were observed in the intratesticular tissue fluid. The androgen concentration in testicular vein blood was much higher ...

P2P data indexing has recently attracted a great many research efforts. For various proposed schemes, there are generally two taxonomies: 1) From a systematic point of view, existing schemes fall into two categories: the over-DHT indexing paradigm, which as a layered manner, indexes data in DHT key space (i.e., over DHT), and the overlay-dependent indexing paradigm, which indexes data directly ...

For improving the routing security of traditional DHT, in this paper, a Multidimensional Mapping Mechanism and a secure routing method based on it are proposed against various routing attacks. The proposed mechanism, which maps the resource search and related peers to a smaller space following the same topology with current DHT protocol to simplify the routing operation and decrease the couplin...

This paper presents the simulation of 4 Quadrature Amplitude Modulation (QAM) orthogonal frequency division multiplexing (OFDM) baseband system and channel estimation which uses inverse discrete Hartley transform (IDHT) and discrete Hartley transform (DHT). As the calculation of DHT and IDHT involves real operations hence the computational complexities are less as compared to DFT and IDFT. More...

One of the mechanisms involved in the regulation of the immune system by steroid hormones could be the monocytic-macrophage system. In this study the effect of the male hormone 5a-DHT on cytokine release by peritoneal macrophages (mΦ) of male and female NZB/BALBc mice was investigated. Macrophages from male mice activated with LPS produced a greater amount of IL-1β (21.8%) (p<0.05) and IL-...

Eight long-term ovariectomized pony mares were treated with either dihydrotestosterone (DHT) benzoate (400 micrograms/kg body weight) in safflower oil or an equivalent amount of oil every other day for 21 d to determine the effects of DHT on follicle stimulating hormone (FSH) and luteinizing hormone (LH) concentrations in blood samples drawn once daily and after administration of three successi...

A ndrogens play a vital role in the maintenance of health in normal men. Testosterone supports bone development and strength, provides anabolic effects for maintenance of lean muscle mass, and contributes to normal sexual function and libido. Circulating testosterone concentrations gradually decline as men age, rendering nearly 20% of men biochemically hypogonadal by age 60. Current guidelines ...

In a dynamic hash table (DHT), peers in a network cooperate to maintain a distributed keyvalue storage. Each peer in a DHT is responsible for storing a subset of keys and their values. Especially in a peer-to-peer system, the peers may not be stable. New peers join and existing peers either fail or leave the system. This process, called churn, requires the DHT to be able to reorganize itself. T...

CONTEXT Testosterone (T) levels decline with age and lower T has been associated with increased mortality in aging men. However, the associations of its metabolites, dihydrotestosterone (DHT) and estradiol (E2), with mortality are poorly defined. OBJECTIVE We assessed associations of T, DHT, and E2 with all-cause and ischemic heart disease (IHD) mortality in older men. PARTICIPANTS Particip...
