BACKGROUND Artificial insemination is not as widely used in horses as in other domestic species, such as dairy cattle and pigs, partly because of the wide variation in sperm quality between stallion ejaculates and partly due to decreased fertility following the use of cooled transported spermatozoa. Furthermore, predictive tests for sperm fertilising ability are lacking. The objective of the pr...

background: sulphites are widely used as a preservative and antioxidant additives in the food and pharmaceutical industries. many types of biological and toxicological effects of sulphites in multiple organs of mammals have been shown in previous studies. objective: the aim of this study was to investigate the effects of sodium metabisulfite (smb) on testicular function and morphometric values ...

introduction: tegrity is the most important component for transferring genetic information sperm dna fragmentation is considered a component of male infertility. its assessment comprises conventional semen analysis of which emphasis is placed on its evaluation in fertility clinics. in this study, we investigate the relationship between sperm parameters of motility, morphology, concentration, an...

Microscopic evaluation of apparent platelet size and morphology was examined in a variety of hematologic disorders. The time of preparation of the blood smear was important. An artifactual increase in platelet size was noted on blood films from 20 normal individuals that were prepared either immediately or 180 min after venipuncture. The clearest differentiation of patient categories was obtain...

Background: Although intrauterine insemination (IUI) is one of the most common methods which is used for male factor and unexplained infertility, the relative influence of various semen parameters on the likelihood of a successful outcome is controversial. Several semen parameters have been evaluated as predictors of a successful outcome with intrauterine insemination. Objective: To evaluate th...

Currently popular systems for classification of spelling words or errors emphasize the learning of phoneme-grapheme correspondences and memorization of irregular words, but do not take into account the morphophonemic nature of the English language. This study is based on the premise that knowledge of the morphological rules of derivational morphology is acquired developmentally and is related t...

Aim: To investigate the prevalence of high levels of sperm DNA damage among men from infertile couples with both normal and abnormal standard semen parameters. Methods: A total of 350 men from infertile couples were assessed. Standard semen analysis and sperm chromatin structure assay (SCSA) were carried out. Results: Ninety-seven men (28% of the whole study group) had a DNA fragmentation index...

BACKGROUND Although the motile sperm organelle morphology examination (MSOME) was developed merely as a selection criterion, its application as a method for classifying sperm morphology may represent an improvement in the evaluation of semen quality. The aim of this study was to determine the prognostic value of normal sperm morphology using MSOME with regard to clinical pregnancy (CP) after in...

BACKGROUND It has previously been shown that the morphology of the P-wave neither depends on atrial size in healthy subjects with physiologically enlarged atria nor on the physiological anatomical variation in transverse orientation of the left atrium. The present study aimed to investigate if different pressures in the left and right atrium are associated with different P-wave morphologies. ...
