BACKGROUND Although much has been published with regard to the columella assessed on the frontal and lateral views, a paucity of literature exists regarding the basal view of the columella. The objective of this study was to evaluate the spectrum of columella deformities and devise a working classification system based on underlying anatomy. METHODS A retrospective study was performed of 100 ...

Since high quality forage is essential in a dairy ration, it is improtant to study new methods of preserving hay. In this trial, the effect of a commercial organic acid preservative on nutirent content and feeding value of alfalfa hay was evaluated. Alfalfa hay from a common field was baled at about 20 percent moisture for a control, and at about 28 percent moisture with addition of 0.1 percent...

Communications to the Editor this device in a previously reported randomized study.’ The methods we used2 to perform MV were nearly the same as those used in that study, but the strategies of tracheal aspiration and instillation were quite different. We performed tracheal aspiration systematically at least every 4 h. This strategy led us to instill 30±12 mIld in the heated-humidifier (Hil) grou...

In a canine model of pulmonary embolism (PE) produced by infusion of autologous blood clots, mean arterial blood pressure (MAP) decreased to 73 +/- 4 mm Hg while cardiac output (CO) decreased to less than 50 percent of baseline. Intravenous infusion of phenylephrine (PHEN) and norepinephrine (NE) restored MAP to somewhat above baseline values. However, only NE restored CO to control levels. The...

This report proposes a standard method to characterize variability and sensitivity of functional neuroimaging experiments. Most functional neuroimaging analyses result in statistic images of signal-to-noise. However, it is essential to examine both signal and noise individually, to characterize sensitivity and to identify artifacts. Confidence intervals simultaneous convey signal and noise but ...

in this study, in vitro non-symbiotic germination of self pollinated seeds, protocorms survival percentage and protocorms growth of phalaenopsis ‘kyoto’ were investigated. for this purpose, five different modified media include vasin and went (vw), murashing and skoog (ms), ½ ms, knudson c (kc), fast that supplemented with two g/l peptone, 15 percent sterile coconut water or two g/l peptone tog...

The objective of this study was to assess the various aspects related to nurses' knowledge and attitudes regarding osteoporosis. METHODS The Facts on Osteoporosis Quiz was used to survey 100 nurses who attended an osteoporosis nursing symposium at the largest hospital in Singapore....

The difference between the disease rates of two groups, one exposed and one not exposed to a suspected aetiological factor, is a useful measure of the risk associated with the factor. This measure is of most interest when the association is considered causal, and has been termed the attributable risk (MacMahon and Pugh, 1970). Expressed as a percentage of the total disease rate in a group (the ...
