background: the purpose of this study is to evaluate effects of teucrium polium (tp) leaf extracts on adenosine monophosphate activated protein kinase (ampk) level in isolated pancreases. materials and methods: in this experimental study, two groups of rats were used as a control group, and diabetic group. in the end of experimental period the animals were sacrificed then pancreas were removed,...

Samples of urine which have been collected by ureteric catheterization are necessarily small in volume, often only a few drops. In order to determine the efficiency of kidney function it may be necessary to measure the specific gravity of these small samples, but it is impossible to use the hydrometer method, which requires a minimum of about 50 ml. of urine. Methods involving the suspension of...

The pore domain of voltage-gated potassium (Kv) channels consists of transmembrane helices S5 and S6, the turret, the pore helix, the selectivity filter, and the loop preceding S6, with a tertiary reentrant structure between S5 and S6. Using biogenic intermediates, mass tagging (pegylation), and a molecular tape measure, we explored the possibility that the first stages of pore formation occur ...

This study examined the association of facial dimensions with respirator fit considering the effect of gender and respirator brand. Forty-one subjects (20 white females and 21 white males) participated in the study. Each subject was measured for 12 facial dimensions using anthropometric sliding and spreading calipers and a steel measuring tape. Three quantitative fit tests were conducted with t...

Body linear measurements, and specifically heart girth (HG), have been shown to be useful predictors of cattle liveweight. To test the accuracy of body linear measurements for predicting liveweight, crossbred dairy cattle of different genotypes were measured and weighed. A total of 352 mature cows and 100 heifers were weighed using an electronic weighing scale and measurements of HG, body lengt...

Transductive methods are useful in prediction problems when the training dataset is composed of a large number of unlabeled observations and a smaller number of labeled observations. In this paper, we propose an approach for developing transductive prediction procedures that are able to take advantage of the sparsity in the high dimensional linear regression. More precisely, we define transduct...

The objectives of the study were to assess: (1) static innominate asymmetry in the sagittal plane, (2) leg length discrepancy (LLD), and (3) the relationship between static innominate rotation and LLD in asymptomatic collegiate athletes. The study was an observational study by design which took place in a University athletic training research laboratory. The participants were twenty-four male a...

The number π is defined as the quotient of a circular object’s circumference with its diameter. In 5th or sixth grade (I can’t quite remember) the teacher asked us to take round objects (coffee cups, pots, balls, whatever we could find) and do this measurement. In preparing this essay, I just repeated this age old exercise, with my own coffee cup and a little round device which measures the hum...

We consider variable selection for high-dimensional multivariate regression using penalized likelihoods when the number of outcomes and the number of covariates might be large. To account for within-subject correlation, we consider variable selection when a working precision matrix is used and when the precision matrix is jointly estimated using a two-stage procedure. We show that under suitabl...

1 present their method for creating the new nipple/areola recipient site in vertical mammaplasty. Any design of a new nipple/areola recipient site must be based on clear objectives. Fortunately , most of these objectives are widely accepted and are not subject to opinion. Ideally, the nipple sits at the apex of the breast, and the areola margin is circular. 2 How well does the authors' techniqu...
