risk of microbial contamination in the cosmetic products and transmission to consumers especially in smuggled preparations is very high. according in this study, the microbial content and pollution some of the sunscreen creams in the market and one sample in official market as witness were evaluated. the microbial content (bacterial total count, fungal count, and presence of pseudomon asaerogin...

introduction: to evaluate the quick cryopreservation technique on parameters of motility, morphology, and vitality of spermatozoa from normozoospermic ejaculates. materials and methods: in this prospective study, a total of 37 normal ejaculates were evaluated according to who criteria, then each sample was divided into two aliquets and sample was cryopreserved with quick freezing method. sperm ...

Eighty samples of bronchoalveolar lavage fluid (BALF) were obtained from the total of 48 patients (22 females and 26 males) and analyzed. Eighteen of those patients were organ transplant recipients. The relationship between polymorphonuclear leukocyte (PMN) count in direct sample and semi quantitative Gram-positive and Gram-negative bacterial content were analyzed in BALF samples. PMN count in ...

INTRODUCTION Increased human immunodeficiency virus (HIV) virulence at infection has been suggested by a meta-analysis based on viral load and CD4 T lymphocytes (CD4) count during acute infection. This result was obtained after secondary analyses of large databases, facilitating the detection of differences. Similar finding in cohorts of more modest sample size would indicate that the effect co...

In this article, we apply count-data travel-cost methods to a truncated sample of visitors to estimate the Peneda-Gerês National Park (PGNP) average consumer surplus (CS) for each day of visit. The measurement of recreation demand is highly specific because it is calculated by number of days of stay per visit. We therefore propose the application of altered truncated count-data models or trunca...

OBJECTIVE To study the value of a single antral follicle count and the additional value of repeated counts in different cycles for the prediction of poor ovarian response in IVF. DESIGN Prospective. SETTING Tertiary fertility center. PATIENT(S) One hundred twenty women undergoing their first IVF cycle. INTERVENTION(S) Measurement of the number of antral follicles on cycle day 3 in two s...

in zero acceptance number sampling plans, the sample items of an incoming lot are inspected one by one. the proposed method in this research follows these rules: if the number of nonconforming items in the first sample is equal to zero, the lot is accepted but if the number of nonconforming items is equal to one, then second sample is taken and the policy of zero acceptance number would be appl...

finger patterns and ridge-counts in a random sample of iranian muslims consisting of 100 males and 100 females are described. the most common finger patterns found were loops, having a frequency of 54.4% u.l., 3.4% r.l. in males and 51.2% u.l. and 4.8% r.l in females. the frequencies of arches and whorls in both sexes were 4% and 38.5% respectively. bimanual and sex differences were indistinct....

ECENTLY, a new system for performing blood counts has been introduced. This is stated to eliminate the major sources of error, i.e., those of drawing blood to a mark accurately, and making an accurate dilution.’3 The basis of this system is a self-filling, disposable glass mioropipette,#{176} combined with a plastic container, prefilled with a suitable diluent. From a single blood sample a hemo...

We consider Markov basis arising from fractional factorial designs with threelevel factors. Once we have a Markov basis, p values for various conditional tests are estimated by the Markov chain Monte Carlo procedure. For designed experiments with a single count observation for each run, we formulate a generalized linear model and consider a sample space with the same sufficient statistics to th...
