Power domain non-orthogonal multiple access combined with a universal filtered multi-carrier (NOMA-UFMC) has the potential to cope fifth generation (5G) unprecedented challenges. NOMA employs power-domain multiplexing support several users, whereas UFMC is robust timing and frequency misalignments. Unfortunately, NOMA-UFMC waveform high peak-to-average power (PAPR) issue that creates negative a...

The aim of this study was to search for clinical and laboratorial data in 46,XY patients with ambiguous genitalia (AG) and normal testosterone (T) synthesis that could help to distinguish partial androgen insensitivity syndrome (PAIS) from 5α-reductase type 2 deficiency (5α-RD2) and from cases without molecular defects in the AR and SRD5A2 genes. Fifty-eight patients (51 families) were included...

This study was designed to investigate the effects of exogenous androgen and resistance exercise on skeletal muscle hypertrophy and the role of the mammalian target of rapamycin (mTOR) signalling during the process. A total of 24 male Sprague-Dawley rats were randomly assigned to sham operation and dihydrotestosterone (DHT) implantation groups with subgroups subjected to sedentary conditions or...

We previously reported the selective loss of AKR1C2 and AKR1C1 in prostate cancers compared with their expression in paired benign tissues. We now report that dihydrotestosterone (DHT) levels are significantly greater in prostate cancer tumors compared with their paired benign tissues. Decreased catabolism seems to account for the increased DHT levels as expression of AKR1C2 and SRD5A2 was redu...

Modern arc processes, such as the modified spray (Mod. SA), have been developed for gas metal welding of high-strength structural steels with which even narrow weld seams can be welded. High-strength joints are subjected to increasingly stringent requirements in terms processing and resulting component performance. In present work, this challenge is met by clarifying influences on hydrogen-assi...

The purpose of this study was to investigate the application of salmon atelocollagen (SAC) to a scaffold. SAC has a low denaturation temperature and needs to be cross-linked before being used as a scaffold. In the present study, SAC was cross-linked by 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide hydrochloride (EDC) or dehydrothermal treatment (DHT). The material properties (degree of cross-l...

Testosterone secreted from the testis is converted to dihydrotestosterone (DHT) in target tissues by 5 alpha-reductase and DHT exerts its action on the nucleus. Since skin is one of the target tissues of androgen we established a system for culturing human skin fibroblasts, and we investigated the conversion of testosterone to DHT in genital and nongenital skin fibroblasts obtained from males a...

Dihydrotestosterone(DHT) has played the pathogenic role in androgenetic alopecia. Patients with genetic deficiency of 5 alpha-reductase type II enzyme, which converts testosterone to DHT, do not have androgenic alopecia. The conversion of testosterone to DHT at hair follicles leads to miniaturization. In scalp biopsy, the tissue DHT level is significantly increased in balded area than non-balde...

The androgen receptor (AR) mediates the growth of benign and malignant prostate in response to dihydrotestosterone (DHT). In patients undergoing androgen deprivation therapy for prostate cancer, AR drives prostate cancer growth despite low circulating levels of testicular androgen and normal levels of adrenal androgen. In this report, we demonstrate the extent of AR transactivation in the prese...

Both protective and nonprotective effects of androgens on the cardiovascular system have been reported. Our previous studies show that the potent androgen receptor (AR) agonist dihydrotestosterone (DHT) increases levels of the vascular inflammatory mediator cyclooxygenase (COX)-2 in rodent cerebral arteries independent of an inflammatory stimulus. Little is known about the effects of androgens ...
