The present study identified the entering and exiting sites for Lutzomyia longiflocosa in rural houses of the sub-Andean region in Colombia. Entering sites were identified with sticky traps set up outside the bedrooms, around the eave openings, and with cage traps enclosing the slits in the doors and windows inside the bedrooms. Exiting sites were identified by releasing groups of females indoo...

Morphological openings and closings form the cornerstones of a rich set of nonlinear operators in signal processing. In this paper, we show how a new morphological operator can be constructed that serves as an approximation to openings and closings for images corrupted by low levels of noise. 2001 Elsevier Science B.V.

Effects of ER-001533 (ER), a newly synthesized vasorelaxant, on the membrane currents were examined in single ventricular cells of guinea pigs. The patch-clamp technique was used in the "whole-cell" and "inside-out" patch configurations. In the whole-cell clamp condition, ER induced a time-independent K'-dominant current, which was inhibited by glibenclamide (1-3 ,uM), suggesting that ER activa...

DNA helices must undergo openings in the form of localized strand separations in order to permit the onset of RNA synthesis or DNA synthesis. The selective control of such DNA helix openings at particular gene loci is the critical feature of gene regulation in prokaryotes and eukaryotes.

Confocal laser scanning microscopy and the potentiometric fluorescence probe tetramethylrhodamine ethyl ester were used to measure changes in membrane electrical potential (DeltaPsi(m)) in individual mitochondria after isolation or in the living cell. Recordings averaged over small mitochondrial populations revealed a gradual decline in DeltaPsi(m) caused by the light-induced generation of free...

introduction: mental foramen (mf) is an important anatomic landmark in dentistry and knowledge about its variable locations (l) and type of emergence (te), has an effect on the sufficiency of local anesthesia and safety of surgical procedures. the aim of this study was to evaluate the l and te of this radiographic landmark as well as the presence of accessory mf, by means of cone-beam computed ...

The hypothesis that dihydropyridine (DHP)-sensitive calcium channels have three distinct modes of gating has been examined. The major prediction is that the relative frequencies among modes depend on DHP concentration while the kinetics within a mode do not. We tested this by studying whole-cell and single-channel calcium currents in neonatal rat and adult guinea pig cardiac myocytes in differe...

We present an algorithm for an early detection of the uncapping process of honeybee brood cells. It is a challenging problem, because the appearance of openings varies highly and the combs surface is crowded by bees. The approach consists of two steps, segmentation of the image and analyzing the segments to give a report about openings.

during rutting period, the male one humped camels, extrudes a balloon like organ from one side of the mouth. twelve heads of the slaughtered one humped camels from different sexes were examined. air was blown through natural openings: mouth, nares, esophagus and trachea. cross and longitudinal sections were made in frozen and formalin fixed specimens. it was concluded that soft palate in one hu...
