Epididymal tumors are uncommon and usually benign, with only 25% of them being malignant. Undifferentiated epididymal carcinoma in particular is extremely rare. We report on a 54-year-old male patient presented with right testicular pain and scrotal mass for the last 6 months. Laboratory investigations were unremarkable but epididymal biopsy result was epididymal undifferentiated carcinoma. Ing...

Caput epididymal wild-type spermatozoa and cauda epididymal spermatozoa from mice null for the adenylyl cyclase Adcy10 gene are immotile unless stimulated by a membrane-permeant cyclic AMP analogue. Both types of spermatozoa exhibit flagellar angulation where the head folds back under these conditions. As sperm proteins undergo oxidation of sulfhydryl groups and the flagellum becomes more stabl...

This paper is a survey on biometrics and forensics, especially on the techniques and applications of face recognition in forensics. This paper describes the differences and connections between biometrics and forensics, and bridges each other by formulating the conditions when biometrics can be applied in forensics. Under these conditions, face recognition, as a non-intrusive and non-contact bio...

Because biometrics-based authentication offers several advantages over other authentication methods, there has been a significant surge in the use of biometrics for user authentication in recent years. It is important that such biometrics-based authentication systems be designed to withstand attacks when employed in security-critical applications, especially in unattended remote applications su...

This retrospective consecutive case series aimed at comparing the results of intracytoplasmic sperm injection (ICSI) with fresh and with frozen-thawed epididymal spermatozoa obtained after microsurgical epididymal sperm aspiration (MESA) in 162 couples. These couples were suffering from infertility because of congenital bilateral absence of the vas deferens (n = 109), failed microsurgical rever...

Multi-biometrics is an exciting and interesting research topic. It is used to recognizing individuals for security purposes; to increase security levels. The recent research trends toward next biometrics generation in real-time applications. Also, integration of biometrics solves some of unimodal system limitations. However, design and evaluation of such systems raises many issues and trade-off...

After a short introduction to biometrics w.r.t. IT security, we derive conclusions on how biometrics should be put to use and how not at all. In particular, we show how to handle security problems of biometrics and how to handle security and privacy problems caused by biometrics in an appropriate way. The main conclusion is that biometrics should be used between human being and his/her personal...
