exudative retinal detachment (erd) may be seen with many ocular pathologies including malignancies. among malignant causes, metastases of breast and lung carcinoma are most common. a 50-year-old woman referred to our clinic with history of decreased visual acuity in her right eye since 3 months before referral. the visual acuity was counting fingers at 2 meters and 6/10 in the right and left ey...

of the object's optical wave‑front in comparison with that of a reference beam. In the paper reviewed here, 1 the DH method used for examining spermatozoa was established with suspensions of protozoa, the flagellated Giardia lamblia (~8–20 µm) and the ciliated Paramecium (~70–140 µm), that bracket the size of a human spermatozoon (~50 µm). The protozoa were placed in 80‑µm‑deep micro‑fluidic ch...

The aim of the study was to determine the degree of compliance of Polish laboratories with World Health Organization (WHO) recommendations, with regard to semen analysis methodology. A survey requesting information about methods of semen analysis was distributed to employees of 55 laboratories. Respondents who had participated in external seminological workshops (31%) were termed certified resp...

Camels represent part of the Arab heritage. The interest in developing assisted reproductive technologies and cryobanking for the conservation of animal genetic resources has recently increased. However, semen collections in camelids present many problems as sitting position during copulation, slow ejaculation and difficult animal handling. In these cases epididymal sperm from slaughtered or re...

background use of medicinal plants with high antioxidant properties could be effective to increase fertility and improvement of disorders such as hormonal imbalance, impotency, oligospermia and immotile sperm. celery (apium graveolens) is rich in antioxidant agents. the leaf and stems of celery contain phenols, furanocoumarin and luteolin. apigenin is one of the main flavonoids of celery leaf. ...

In a recent Research Article by Sutovsky et al., the authors interpret their results to mean that in the normal animal the epididymis ‘...provides a mechanism for sperm quality control...’ and that ‘ubiquitinated (i.e. defective) sperm are subsequently phagocytosed by the epididymal epithelial cells’ (Sutovsky et al., 2001). This was based on observations that abnormal sperm were ubiquitin-labe...

Recent evidence that histamine is present in basophilic kucocytes (Graham, Wheelwright, Parish, Marks and Lowry, 1952; Code and Mitchell, 1954) as well as in tissue mast cells (Riley and West, 1953) has created fresh interest in these cells. Knowledge of variations in the number of crulating basophils is scanty owing to the inaccuracy of smear techniques, but the introduction of a chamber-count...

We work out the relation between Chern-Simons, 2d Yang-Mills on the cylinder, and Brownian motion. We show that for the unitary, orthogonal and symplectic groups, various observables in Chern-Simons theory on S3 and lens spaces are exactly given by counting the number of paths of a Brownian particle wandering in the fundamental Weyl chamber of the corresponding Lie algebra. We construct a fermi...

The ratio of the neutron-induced fission cross-sections of Am and U was measured in the energy range from 0.5 to 20 MeV with uncertainties of ≈4%. The experiment was performed at the CERN n TOF facility using a fast ionization chamber. With the good counting statistics that could be achieved thanks to the high instantaneous flux and the low backgrounds, the present results are useful for resolv...
