As such, our predictions represent some of the principal unresolved questions that we believe deserve special investigative attention in the coming decade.”
“Nocardiosis is caused by Gram-positive aerobic actinomycetes that live in soil and are known to be responsible for opportunistic infections. The condition mostly affects the lung, brain or skin. Here, we present a 24-year-old Japanese woman who had had systemic lupus erythematosus since the age of 20 years, and lupus nephritis since the age of 23 years. She developed cutaneous lymph duct-type nocardiosis due to
Nocardia araoensis while on immunosuppressant therapy. The patient had cutaneous findings from the right inguinal region to the right lower thigh and did
not have lesions on the rest of the body. Minocycline and co-trimoxazole were co-administrated, and her condition improved. To our knowledge, see more this is the first case in which N. araoensis was detected by analysis on rRNA base sequence in skin lesions.”
“Cryopreservation of ovarian cortex has important implications in the preservation of fertility and biodiversity in animal species. Slow freezing of cat ovarian tissue resulted in the preservation of follicular morphology and in the follicular development after xenografting. Vitrification has been check details recently applied to ovarian tissues of different species, but no information is available on the effect of
this method on feline ovarian cortex. Moreover, meiotic competence of fully grown oocytes isolated from cryopreserved tissue has not been reported. The aim of this GSK1120212 nmr study was to evaluate the effect of vitrification of feline ovarian cortex on follicular morphology and oocyte integrity, as well as meiotic competence. A total of 352 fragments (1.52 mm3) were obtained from ovarian cortical tissues: 176 were vitrified and 176 were used fresh as control. Histological evaluation of fresh and vitrified fragments showed intact follicles after cryopreservation procedures with no statistically significant destructive effect from primordial to antral follicles. After IVM, oocytes collected from vitrified ovarian fragment showed a higher proportion of gametes arrested at germinal vesicle (GV) stage compared to those isolated from fresh control tissue (33.8% vs 2.9%; p < 0.001). However, oocytes isolated from vitrified tissues were able to resume meiosis, albeit at lower rate than those collected from fresh tissues (39.8% vs 85.9%; p < 0.00001). Vitrification induced changes in the organization of cytoskeletal elements (actin microfilaments and microtubules) of oocytes, but significantly only for actin network (p < 0.001). Finally, chromatin configuration within the GV was not affected by the cryopreservation procedure.
