Formulation of Bawang Dayak (Eleutherine Bulbosa (Mill.) Urb.) Extract Into a Gel Toothpaste [PDF]
, 2016 Dental caries is a disease of tooth decay that starts from the surface and evolve in the direction of the tooth, beginning with the process of tooth demineralization. Tooth decay is usually caused by the bacterium Streptococcus mutans.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Cognitive decline is a disabling and variable feature of Parkinson disease (PD). While cholinergic system degeneration is linked to cognitive impairments in PD, most prior research reported cross‐sectional associations. We aimed to fill this gap by investigating whether baseline regional cerebral vesicular acetylcholine transporter ...

Dynamic Panel Estimation and Homogeneity Testing Under Cross Section Dependence [PDF]
This paper deals with cross section dependence, homogeneity restrictions and small sample bias issues in dynamic panel regressions. To address the bias problem we develop a panel approach to median unbiased estimation that takes account of cross section ...

Arthritis Care &Research, EarlyView.Objective Antinuclear antibodies (ANAs) are present at high titers in 2% of the general population, but their clinical significance in individuals without an autoimmune (AI) disease is not known. We tested the hypothesis that the presence of a high ANA titer in non‐AI conditions is associated with disease.

Testing for homogeneity of gametic disequilibrium across strata
BMC Genetics, 2007 Background Assessing the non-random associations of alleles at different loci, or gametic disequilibrium, can provide clues about aspects of population histories and mating behavior and can be useful in locating disease genes.

Homogenizing Efficiency Test Studies
Journal of Dairy Science, 1943 Summary 1. With very careful control procedures, a plant should be able to meet the U. S. Public Health Service homogenizing efficiency test most of the time. It is felt, however, that a more liberal test would be more practical since there appears to be no reason for such a rigid test. 2. The Babcock test as per modification presented is the

A ROTTERDAM APPLICATION TO INTERNATIONAL TRADE IN FRESH APPLES: A DIFFERENTIAL APPROACH [PDF]
A Rotterdam import allocation model is used to fit import data for fresh apples in four importing markets important to U.S. apple exporters. Nested tests rejected homotheticity but could not reject homogeneity, symmetry, or separability among import ...

Testing homogeneity for Poisson processes
, 2011 Summary: We developed an asymptotically optimal hypothesis test concerning the homogeneity of a Poisson process over various subintervals. Under the null hypothesis, maximum likelihood estimators for the values of the intensity function on the subintervals are determined, and are used in the test for homogeneity.
