Investigators at August Pi Sunyer Biomedical Research Institute and University of Barcelona performed a prospective surveillance study in 14 patients with immune-mediating relapsing symptoms of post-herpes simplex encephalitis (HSE).

OBJECTIVE The aim of this study was to examine the possible association between umbilical artery pulsatility index (PI) at 10-14 weeks of gestation and either increased fetal nuchal translucency (NT) or fetal chromosomal abnormality. DESIGN This was a prospective study of women undergoing chorionic villus sampling (CVS). SUBJECTS A total of 458 women undergoing CVS were studied; in 418 case...

Conservative management has been the mainstay of treatment for simple extra-articular distal radius fractures. Several factors, such as quality of definitive casting, have been implicated in the risk of fracture re-displacement during follow-up. Objective assessments of the quality of casting using various indices have been documented in literature, although overall evidence remains scant, and ...

In this experiment, the correlation between antigenemia and specific antibody responses in Toxoplasma gondii-infected rabbits was assessed. We injected 1,000 T. gondii tachyzoites (RH) subcutaneously into 5 rabbits. Parasitemia, circulating antigens, and IgM and IgG antibody titers in blood were tested by ELISA and immunoblot. For detection of parasitemia, mice were injected with blood from rab...

Mycobacterium tuberculosis RecA intein (PI-MtuI), a LAGLIDADG homing endonuclease, displays dual target specificity in response to alternative cofactors. While both ATP and Mn(2+) were required for optimal cleavage of an inteinless recA allele (hereafter referred to as cognate DNA), Mg(2+) alone was sufficient for cleavage of ectopic DNA sites. In this study, we have explored the ability of PI-...

Tomato plants were inoculated with Meloidogyne incognita at initial populations (Pi) of 0, 1, 10, 50, 100, and 200 (x 1,000) eggs per plant and maintained in a growth chamber for 40 days. Total fresh biomass (roots + shoots) at harvest was unchanged by nematode inoculation with Pi of 1 x 10 eggs or less. Reductions in fresh shoot weight with increasing Pi coincided with increases in root weight...

Evidence is presented indicating that oxidants are generated in lungs of patients with the adult respiratory distress syndrome (ARDS). The evidence was derived from observations that alpha-1-PI, recovered in bronchoalveolar lavage (BAL) fluid, had been inactivated by oxidation, presumably oxidation of the methionyl residue in the reaction site of the molecule. This was indicated by findings tha...

BACKGROUND The aims of this study were to evaluate the effect and mechanism of a traditional Chinese medicine formula: Tongxieyaofang (TXYF) on Rats with Post Infectious Irritable Bowel Syndrome (PI-IBS). METHODS SD male rats in adult were used to model PI-IBS and treated with TXYF at three dosage for 14 consecutive days, and then visceral sensation and the frequency of stool in PI-IBS rats w...
