BACKGROUND To determine the impact of self-perceived halitosis on social interactions, and the effect of using an oral rinse for management of halitosis. METHODS A survey among a representative sample of the Dutch population (n = 1082), and a pre-post study among a sample of consecutive coming-by volunteers (n = 292). RESULTS Participants of the representative sample rated their oral odor a...

the phenomenological model of khossravi and connors (1992) has been adopted to calculate the electrophoretic mobility of drugs at different concentrations of solvents in a binary mixture. the accuracy and predictability of the model have been evaluated employing 14 experimental data sets by using average percentage mean deviation (apmd). the obtained apmd for correlative and predictive studies ...

Sputum culture is more sensitive than smear microscopy for the diagnosis of tuberculosis and facilitates the performance of drug susceptibility testing. Initiatives are underway in high burden countries to expand capacity for sputum culture to improve TB case detection and patient care. Contamination by other bacteria and fungi is a limitation of sputum culture despite laboratory decontaminatio...

In a collaboration involving 11 groups with research interests in cerebral amyloid angiopathy (CAA), we used a two-stage process to develop and in turn validate a new consensus protocol and scoring scheme for the assessment of CAA and associated vasculopathic abnormalities in post-mortem brain tissue. Stage one used an iterative Delphi-style survey to develop the consensus protocol. The resulta...

The aim of the study was to determine whether rinsing with a mouthwash after brushing with a fluoridated toothpaste affected oral fluoride (F) retention and clearance compared with an oral hygiene regime without mouthwash. In this supervised, single-blind study, 3 regimes were compared: (A) brushing for 1 min with 1 g of 1,450 microg F/g NaF toothpaste followed by rinsing for 5 s with 10 ml wat...

The inhibitory effects of Adhatoda vasica ethanolic leaf extract (AVELE) against Listeria monocytogenes were examined to assess its potential to preserve minimally processed meat products safely. The total phenolic, flavonoid, and alkaloid levels in AVELE were 10.09 ± 4.52 mg of gallic acid equivalents (GAE)/g, 22.43 ± 1.62 mg of quercetin equivalents/g, and 19.43 ± 3.90 mg/g, respectively. AVE...

We have developed and tested two complementary methods for making time-lapse synchrotron X-ray diffraction (XRD) measurements of the growth of synthetic corrosion layers using a protocol for producing copper(I) chloride (nantokite), on copper as a test. In the first method, a copper coupon was spin-coated with saturated copper(II) chloride solution in air while the surface was characterized in ...

Two-phase flow through capillary channels is considerably different from two-phase flow through larger channels: viscous (μu/d) and interfacial (γ/d) stresses, both inversely proportional to the diameter, are more important than inertial (ρu) and gravitational (ρgH) stresses. A reasonable definition of the term capillary might be obtained by requiring the dominance of surface tension forces ove...
