Purnose The incorporation of polymers into artificial tears both increases the thickness of the precorneal tear film and decreases the rate of drainaae of the for8nulations. On the basis of these effects, we hypothesized that a time study of the artificial increase in tear volume induced by such formulations could be a useful method of assessing their precorneal residence time. Methods New Zeal...

Early surgery is vital in the treatment of pancreatic cancer, which is often fatal. However, there is currently no useful noninvasive biomarker to screen for pancreatic cancer. Studies have documented that many salivary molecules can be used to detect systemic diseases. We investigated whether salivary miRNAs are useful biomarkers for detecting resectable pancreatic cancer. Using an Agilent mic...

Here we investigate the effect of electromagnetic waves with high radio frequency radiation on the antioxidant enzyme activities and seed germination of Zea mays. Three groups of Zea mays seeds were used in this study. The first group was only exposed to RF radiation emitted from the mobile phone simulator. The second group was only exposed to RF radiation emitted from the mobile phone simulato...

The aim of this study was to improve the transdermal permeation of Diclofenac Soduim. Permeation studies were carried out in -vitro using Cellophane Membrane. Topical gel formulations of diclofenac sodium were prepared by using Carbopol 934, Carbopol 940, sodium carboxymethylcellulose (NaCMC), polymer as a gel-forming material that is biocompatible and biodegradable. The skin permeation enhance...

We have carried out power spectrum, time-spectrum and bispectrum analyses of the long-term series of the radiocarbon concentrations deduced from measurements of the radiocarbon content in tree rings for the last 8000 years. Classical harmonic analysis of this time series shows a number of periods: 2400, 940, 710, 570, 500, 420, 360, 230, 210 and 190 years. A principle feature of the time series...

El propósito este trabajo describir abordaje terapéutico diodo 940 nm. A consulta odontológica se presentan diversos casos pacientes adultos ambos s...

Twelve new localities are reported for the following four Embiratermes species: E. ignotus Constantino, 1991; latidens (Emerson & Banks, 1957); silverstrii (Emerson, 1949); and spissus 1957). The extend distribution span from 940 km up to 1,800 km. is recorded beyond Amazonia first time. enteric valve armature workers of these species provided.
