Zona pellucida induced acrosome reaction, sperm morphology, and sperm-zona binding assessments among subfertile men
Purpose: The study aimed to evaluate the relationship between the zona pellucida induced acrosome reaction (ZIAR) and (i) percentage normal spermatozoa as well as (ii) sperm-zona pellucida binding potential among men ...
Relationship between Human Sperm Morphology and Acrosomal Function
Purpose: In this study, we investigated the relationship between functionality of the acrosome and sperm morphology. Methods: Acrosome reaction (AR) was separately determined in live and dead sperm and in those with normal, ...
Physiological induction of the acrosome reaction in human sperm: Validation of a microassay using minimal volumes of solubilized, homologous zona pellucida
Purpose: To develop a method that could accommodate microvolumes of solubilized human zona pellucida (ZP) and sperm for assessing the induction of the acrosome reaction. Methods: A microassay using 1 μl of 2.5, 1.25, 0.6, ...
Seasonal changes in human sperm chromatin condensation
Purpose: The aim of this study was to investigate possible seasonal changes in human sperm parameters, especially chromatin condensation. Method: In a first run, 3155 patients attending the andrological outpatient clinic ...

Recombinant human bone morphogenetic protein-2 for treatment of open tibial fractures a prospective, controlled, randomized study of four hundred and fifty patients
Background: The treatment of open fractures of the tibial shaft is often complicated by delayed union and non-union. The objective of this study was to evaluate the safety and efficacy of the use of recombinant human bone ...
Traumatic dislocation of the atlanto-occipital joint
We present four patients who had sustained a traumatic dislocation of the atlanto-occipital joint. The diagnosis was initially missed in two patients. One patient, who was neurologically intact, was treated non-operatively. ...
Childhood drug-resistant tuberculosis in the Western Cape Province of South Africa
Aim: Continued surveillance of drug resistance amongst children presenting with culture-confirmed tuberculosis to a tertiary care hospital and to community clinics. Methods: Drug susceptibility testing for isoniazid and ...
Nosocomial transmission of Mycobacterium tuberculosis in kangaroo mother care units: A risk in tuberculosis-endemic areas
Background and aim: Kangaroo mother care (KMC) has become the standard of care for low-risk preterm babies born in developing countries. However, the potential risk of nosocomial transmission of Mycobacterium tuberculosis ...
