BACKGROUND To minimize the inflammatory reaction and improve healing, a new modified dermal substitute composed of an atelocollagen, chondroitin-6-sulfate, and amniotic membrane (AM) was applied to full-thickness skin defects in a pig. Atelocollagen was extracted from bovine skin, and two modified dermal substitutes were generated according to the cross-linking type. METHODS The AM-collagen d...

Dihydrotestosterone (DHT) is the primary metabolite of testosterone in the prostate and skin. Testosterone is converted to DHT by 5alpha-reductase, which exists in two isoenzyme forms (types 1 and 2). DHT is associated with development of benign prostatic hyperplasia (BPH), and reduction in its level with 5alpha-reductase inhibitors improves the symptoms associated with BPH and reduces the risk...

Abstract Dedicated hybrid transmission (DHT) is the developing trend of transmissions. This paper studies different types DHTs regarding structure, function, and performance. Firstly, structure function well-known in market are discussed analyzed. Through analysis, reasonability necessity modes electric motor power requirements that lie behind derived. Secondly, dynamics further compared with d...

Dry hard turning (DHT) provides an effective process for finishing high-hardness materials. Machining-induced surface integrity has a direct impact on functional performance. This study compares the effects of DHT and grinding processes machining-induced fatigue performance 18CrNiMo7-6 steel. The experiment were carried out by using polycrystalline cubic boron nitride tool corundum wheel, respe...

AIMS To evaluate the characteristics of manual haemoglobin methods in use in Malawi and provide evidence for the Ministry of Health in Malawi to enable them to choose a suitable method for district hospitals. METHODS Criteria on accuracy, clinical usefulness, user friendliness, speed, training time, and economic costs were determined by local health professionals and used to compare six diffe...

Blockchain technology gained popularity thanks to its decentralized and transparent features. However, it suffers from a lack of privacy as stores data publicly has difficulty handle updates due main feature known immutability. In this paper, we propose storage access framework that combines blockchain with Distributed Hash Table (DHT), role-based control model, multiple encryption mechanisms. ...

A search engine, like Google, is built using two pieces of infrastructure a crawler that indexes the web and a searcher that uses the index to answer user queries. While Google's crawler has worked well, there is the issue of timeliness and the lack of control given to end-users to direct the crawl according to their interests. The interface presented by such search engines is hence very limite...

The ovine sexually dimorphic nucleus (oSDN) is 2 times larger in rams than in ewes. Sexual differentiation of the oSDN is produced by testosterone exposure during the critical period occurring between gestational day (GD)60 and GD90 (term, 147 d). We tested the hypothesis that testosterone acts through the androgen receptor to control development of the male-typical oSDN. In experiment 1, pregn...

BACKGROUND During testosterone (T) therapy, T is partly converted to 17beta-estradiol (E2) and 5alpha-dihydrotestosterone (DHT). Effects of age, testosterone dose, and body composition on total and free E2 and DHT levels are unknown. OBJECTIVE We evaluated age and dose-related differences in E2 and DHT levels in response to graded doses of testosterone enanthate in young and older men. METH...

Polycystic ovary syndrome (PCOS) causes vascular damage to arteries; however, there are no data for its effect on veins. Our aim was to clarify the effects of dihydrotestosterone (DHT)-induced PCOS both on venous biomechanics and on pharmacological reactivity in a rat model and to test the possible modulatory role of vitamin D3 (vitD). PCOS was induced in female Wistar rats by DHT treatment (83...
