Abstract: Vasoactive intestinal peptide (VIP) has recently been detected in rat ovaries and has been shown to stimulate steroidogenesis by cultured rat granulosa cells. In this study we investigated whether the VIP-messenger RNA (mRNA) can be detected in the ovaries, thus suggesting local synthesis of the peptide. To study VIP-gene expression, a sensitive RNA detection assay which uses in vitro transcribed RNA probes corresponding to specific exons of the VIP gene was developed. Using this method, an approximately 2000-base RNA band containing the coding sequences for VIP was detected in rat ovaries. This RNA also contains the coding sequences for the VIP-related peptide (peptide-histidine-methionine). An identical VIP-encoding RNA was previously identified in the rat cerebral cortex. However, the VIP-mRNA quantity in the cortex was 12-fold-higher as compared to the ovaries. These results may reflect the differences in VIP concentration in the two organs. The finding of VIP-encoding mRNA in the rat ovaries suggests a local synthesis of VIP in the ovaries.
Which is the apt title for the abstract? option1: Detection of vasoactive intestinal peptide-encoding messenger ribonucleic acid in the rat ovaries. option2: Intravascular balloon embolization of a large mid-basilar artery aneurysm. Case report.
answer:
Detection of vasoactive intestinal peptide-encoding messenger ribonucleic acid in the rat ovaries.

Abstract: This study of suction lipectomy aspirates from 15 consecutive patients was undertaken to biochemically quantitate the blood-to-fat ratios of the aspirates. A wide variation in the blood-to-fat ratios (8 to 54 percent) was noted, but the authors failed to demonstrate any relationship between the blood-to-fat ratios and the suction lipectomy operative site. Prophylactic measures to allow treatment of patients in a consistently safe manner include carefully screening of patients to exclude those with bleeding disorders or significant illnesses, perioperative oral iron therapy, infiltrating the operation site with a dilute epinephrine solution, hydrating the patients adequately perioperatively, using smaller-diameter cannulas for the aspiration, minimizing aspiration once the aspirate turns grossly bloody, and limiting the aspirate to a volume of less than 1750 ml for any operative procedure.
Which is the apt title for the abstract? option1: Quantitative analysis of blood and fat in suction lipectomy aspirates. option2: Evidence for nongastrin-mediated somatostatin inhibition of parietal cell function.
answer:
Quantitative analysis of blood and fat in suction lipectomy aspirates.

Abstract: Twenty one cases of amyloidosis of the lower respiratory tract were seen at a single center. In three patients, multifocal bronchial amyloid plaques led to stenosis and atelectasis, and in two, small pseudotumor masses were an incidental bronchoscopic finding. Two patients had nodular parenchymal amyloidosis, in one of whom the lesions were progressive and in the other static. Fifteen patients had diffuse parenchymal amyloidosis. Two of these had severe interstitial involvement and died in respiratory failure; eight had congestive cardiac failure, and parenchymal amyloidosis was a post-mortem finding; two had senile cardiorespiratory amyloidosis, also found at autopsy; and in three, the amyloidosis was associated with malignancy. The degree of respiratory embarrassment seemed to be related to the amount of amyloid in the gas diffusion zones, irrespective of the etiology of amyloidosis.
Which is the apt title for the abstract? option1: Amyloidosis of the lower respiratory tract. Clinical and pathologic features in a series of 21 patients. option2: Elastic properties of muscles measured at the elbow in man: II. Patients with parkinsonian rigidity.
