In a new 340B controversy, OPA rebuffs a court ruling.

BACKGROUND To evaluate the ocular pulse amplitude (OPA), the posterior pole asymmetry analysis (PPAA), the peripapillary retinal nerve fiber layer (RNFL) thickness, the ganglion cell layer (GCL) thickness, macular thickness and visual field testing in migraine patients without aura. METHODS In this prospective, cross-sectional and comparative study 38 migraine patients and 44 age and sex matc...

Bordetella pertussis is the causative agent of pertussis (whooping cough). Despite high vaccination coverage, pertussis remains a significant disease in many countries. Besides vaccination, transient carriage of Bordetella spp. or other cross-reacting organisms adds to the immunity against pertussis. However, the various immunological mechanisms conferring protection remain largely unknown. In ...

Lipooligosaccharide (LOS) has been implicated in the adhesion and invasion of host epithelial cells. We examined the adhesive and invasive abilities of isogenic gonococcal opacity-associated outer membrane protein-negative, pilus-positive (Opa-Pil+) Neisseria gonorrhoeae strains expressing genetically defined LOS. Strain F62 (Opa-Pil+), expressing the lacto-N-neotetraose and the galNac-lacto-N-...

BACKGROUND Few studies have examined which lifestyle factors relate to the development of fat distribution. Therefore, the identification of the determinants of changes in fat deposition is highly relevant. METHODS The association between the change in physical activity (PA) and the subsequent changes in regional body fat distributions was examined. In total, 1,236 men and 1,201 women were in...

Classical target detection can suffer large error probabilities in noisy and lossy environments when noise photons are mistaken for signal photons reflected from an object. It has been shown theoretically that the correlation between entangled photons can be used to better discriminate between the signal photons reflected by an object and noise photons, thus reducing the probability of error [1...

In a randomized double-blind trial in healthy Israeli infants in Israel who received the 13-valent or 7-valent pneumococcal conjugate vaccine (PCV13 or PCV7, respectively) at 2, 4, 6, and 12 months, PCV13 significantly reduced nasopharyngeal (NP) colonization of serotypes 1, 6A, 7F, 19A, cross-reacting 6C, and the common PCV7 serotype 19F, from ages 7 to 24 months. No differences were observed ...

Previous reports (Drescher, D. G., and Lee, K. S. (1978) Anal. Biochem. 84, 559-569; Lee, K. S., and Drescher, D. G. (1978) Int. J. Biochem. 9,457-467) have shown that high performance liquid chromatographic analysis of amino acids with the o-phthaldialdehyde/2mercaptoethanol reagent (OPA/P-ME) is one of the most sensitive procedures currently available for micro amino acid analysis. In the pre...

Future wireless communications technology should fulfill the demands of multimedia applications, interactive internet service, high data rates and power efficiency. However, wireless channel is affected by multipath fading that can degrade the system performance. To overcome the problem, cooperative communication has been introduced to be an efficient diversity technique to combat the multipath...

Acute salpingitis complicating cervical gonococcal infection is a significant cause of infertility. Relatively little data are available concerning the pathophysiologic mechanisms of this disease. A cohort of 243 prostitutes residing in Nairobi were followed between March 1985 and April 1988. Gonococcal cultures were performed at each visit, and acute salpingitis was diagnosed clinically. Serum...
