Role of information systems in public health services.
The purpose of this review is to establish a conceptual framework on the role of information systems in public health care. Information is indispensable for effective management and development of health services and ...
Detection of p53 gene mutations in oral squamous cell carcinomas of a black african population sample
Mutations in the p53 gene have been reported in head and neck carcinomas. We determined the p53 mutation profile in 55 oral squamous cell carcinomas (OSCCs) from a black African population sample. DNA from all the patients ...
Deletion mapping of 39 random isolated Y-chromosome DNA fragments
Thirty-nine recombinants isolated from a Y chromosome-specific library were deletion mapped. Seven deletion intervals were defined by hybridization of probes to DNA of eight individuals with aberrant Y chromosomes. Extreme ...

A comparative analysis of embryo implantation potential in patients with severe teratozoospermia undergoing in-vitro fertilization with a high insemination concentration or intracytoplasmic sperm injection
The objective of this study was to assess fertilization, implantation and pregnancy rates in infertile patients with severe teratozoospermia [P (poor prognosis) pattern sperm morphology assessed by strict criteria] treated ...
The ability of the hemizona assay to predict human fertilization in different and consecutive in-vitro fertilization cycles
The objective of this prospective study was to examine the ability of the hemizona assay (HZA) to predict fertilization outcome of mature, pre-ovulatory oocytes under in-vitro fertilization (IVF) conditions. Since a large ...
The effect of pentoxifylline on sperm movement characteristics and zona pellucida binding potential of teratozoospermic men
This study investigates the effect of pentoxifylline on sperm movement and zona pellucida binding. Spermatozoa from nine teratozoospermic patients (10.2 ± 6% normal forms) were included in the study. Test samples were ...
The Acridine Orange test: Determining the relationship between sperm morphology and fertilization in vitro
The prediction of human fertilization is an important aspect of research protocols dealing with male fertility. Sperm DNA has been reported to be an indicator of human sperm fertility potential. The Acridine Orange test ...
The evaluation of morphological characteristics of human spermatozoa according to stricter criteria
The evaluation of the morphology of human spermatozoa varies widely between and sometimes even within laboratories. The purpose of this study was to determine whether the method that has been developed in our laboratory ...
The influence of solubilized porcine zona pellucida protein on the binding capacity of human spermatozoa
The acrosome reaction, sperm-zona pellucida binding, sperm-oolemma binding/fusion and subsequent fertilization are known to be influenced by homologous as well as heterologous follicular fluid and zona pellucida protein. ...
