The diurnal variation of the gross alpha (alpha) radioactivity in the air near the ground and the gamma (gamma) radioactivity emitted from the ground have been monitored in North-eastern Greece. Meteorological information comprising air temperature and humidity has been simultaneously recorded. Over a period of the 24h of a typical day, the variation of alpha-radioactivity reaches a peak in the...

Raised alpha-fetoprotein concentrations were found at 29 and 30 weeks' gestation in the amniotic fluid and maternal serum of a woman who presented in her seventh pregnancy with apparent polyhydramnios. The fetus had multiple abnormalities including gross distension of the bladder resulting from absence of the urethra, intestinal artresia, and a congenital heart defect.

A point mutation in a highly conserved region of the beta 1 subunit, Asp130 to Ala (D130A) substitution, abrogates the Arg-Gly-Asp (RGD)-dependent binding of alpha 5 beta 1 to fibronectin (FN) without disrupting gross structure or heterodimer assembly. The D130A mutation also interferes with binding to invasin, a ligand that lacks RGD sequence. In spite of the lack of detectable FN binding by a...

Three [35S]methionine-labeled polypeptides released by T47D human breast cancer cells have been identified as corresponding to two proteins previously described in breast gross cystic disease fluid. A Mr 43,000 protein was immunoprecipitated by polyclonal antibodies to the Zn-alpha 2-glycoprotein. A Mr 18,000 and a Mr 13,000 polypeptide were both immunoprecipitated by four monoclonal antibodies...

OBJECTIVE To explore the therapeutic efficacy and safety of malignant liver tumor treatment by radiofrequency ablation (RA) combined with low frequency ultrasound radiation with microbubbles (LFURM). METHODS Retrospective analysis of 25 patients with malignant hepatic tumors treated by RA/LFURM in the Department of Hepatobiliary Surgery of Kunming General Hospital affiliated to Chengdu Milita...

The role of 5-hydroxytryptamine (5-HT) in pentobarbitone (PB) sleeping time, gross behaviour, electrical activity of the brain and serum 5-HT level was studied in Holtzman strain adult albino rats following treatment with M. oleifera (MO). MO (350mg/kg) caused inhibition of awareness, touch response, motor activity, righting reflex, and grip strength. It significantly increased the PB sleeping ...

We report on a case of juvenile granulosa cell tumor of the testicle in a neonate, a rare testicular tumor in children. No genital ambiguity, anatomic abnormalities, nor sex chromosome aneuploidy was noted in this patient. In our case, despite positive staining for alpha-fetoprotein which is most consistent with yolk sac tumors, all clinical, gross anatomic, histologic, and other immunohistolog...
