High dimensional pose state space is the main challenge in articulated human motion tacking. In this paper, we propose a novel generative approach in the framework of artificial immune model, by which we try to widen the bottleneck with effective search strategy embedded in the extracted state subspace. Firstly, we learn the latent space of pose state and propose a manifold reconstruction metho...

purpose: the aim of this study was to test the in vitro sensitivity of lymphocytes of patients with head and neck cancer against gamma irradiation and also to find out if the frequencies of chromosomal aberrations correlate with side effects of radiotherapy. patients and methods : peripheral blood of 101 patients with head and neck cancer was collected before the onset of radiotherapy, cultured...

OBJECTIVES To obtain knowledge on male reproductive toxicity of inorganic lead at current European exposure levels and to establish lowest adverse effect levels, if any. METHODS A cross sectional survey of the semen of 503 men employed by 10 companies was conducted in the United Kingdom, Italy, and Belgium. The mean blood lead concentration was 31.0 microg/dl (range 4.6-64.5) in 362 workers e...

BACKGROUND A high body mass index (BMI) has been associated with reduced semen quality and male subfecundity, but no studies following obese men losing weight have yet been published. We examined semen quality and reproductive hormones among morbidly obese men and studied if weight loss improved the reproductive indicators. METHODS In this pilot cohort study, 43 men with BMI > 33 kg/m² were f...

Sperm DNA Fragmentation has been extensively studied for more than a decade. In the 1940s the uniqueness of the spermatozoa protein complex which stabilizes the DNA was discovered. In the fifties and sixties, the association between unstable chromatin structure and subfertility was investigated. In the seventies, the impact of induced DNA damage was investigated. In the 1980s the concept of spe...

We have approached the problem of refrigerated storage of epididymal sperm samples from red deer by comparing three options: storing the genital (testicles within the scrotum), diluting the semen in extender or diluting the semen in extender supplemented with an anti-oxidant. Twenty-nine pairs of testes were collected. Spermatozoa from one of each of the pairs were immediately recovered, and di...

Background: Sperm DNA is susceptible to oxidative damage due to intrinsic and extrinsic factors which cause oxidative stress and due to limited DNA damage detection and repair mechanism. Reactive oxygen species (ROS) are the chief cause of sperm DNA damage. So, this study was planned to assess oxidative stress levels and correlate with sperm DNA damage. Material and Method: The study included 3...

introduction: telomeric repeat amplification protocol assay (trap assay) is a standard established technique to detect the activity (expression) of telomerase in the cancerous samples. it includes a time-consuming procedure that has significant drawbacks such as high cost, complicacy, time-consuming procedure, equipment-dependent steps and false-positive signals caused by inclusion of pcr insid...
