BACKGROUND
Multiple Chemical Sensitivity (MCS) is a chronic condition characterized by reports of recurrent symptoms in response to low level exposure to various chemical substances. Recent findings suggests that dysregulation of the immune system may play a role in MCS
Macrocyclic calixarene molecules were modified with functional groups of different polarities at the upper rim and subsequently grafted to mesoporous silica supports through a single Si atom linker. The resulting materials were characterized by thermogravimetric analysis, UV-visible spectroscopy,
Materials were synthesized for the recovery of n-butanol from dilute aqueous solutions, as may be useful for applications in biofuel-water separations. These materials are composed of hydrophobic, cavity-containing calixarenes covalently bound directly to porous, hydrophilic silica supports through
The primary products of n-butoxy and 2-pentoxy isomerization in the presence and absence of O(2) have been detected using pulsed laser photolysis-cavity ringdown spectroscopy (PLP-CRDS). Alkoxy radicals n-butoxy and 2-pentoxy were generated by photolysis of alkyl nitrite precursors (n-butyl nitrite
This study was conducted to clarify the effect of the n-butanol fraction from the anomalous fruits of Gleditsia sinensis LAM. (NBGS) on experimental allergic rhinitis. NBGS (100, 200, 400 mg/kg, p.o.) dose-dependently inhibited nasal symptoms (sneezing and nasal rubbing) and dye leakage induced by
To study the effects of extracts of Enteromorpha prolifera on the growth of the four species of red tide microalgae (Amphidinium hoefleri, Karenia mikimitoi, Alexandrium tamarense and Skeletonema costatum), the extracts were extracted with five solvents (methanol, acetone, ethyl acetate, chloroform
Scorpion envenomation has been considered a public health issue around the world. Tityus serrulatus represents a specie of major medical importance in Brazil due to mortality rates of approximately 1% among children and elderly populations. The aim of this work was to evaluate the in vivo
OBJECTIVE
To investigate the effect of Behçet's disease on olfactory function, the nasal mucosa, and nasal symptoms.
METHODS
A total of 30 patients with Behçet's disease and 30 healthy individuals volunteered to enroll in the study. Any condition leading to olfactory dysfunction was a criterion for
The phagocytic activity of peritoneal exudate cells (PECs) harvested from peritoneal cavity of mice after a single intraperitoneal (i.p.) treatment with poly(butylcyanoacrylate) nanoparticles (PBCN) and their probable metabolites [poly(cyanoacrylic acid) (PCAA) and n-butanol] was investigated in an
Dental caries is a chronic bacterial infectious disease caused by multiple factors, with Streptococcus mutans (S. mutans) as the main cariogenic bacteria. Trollius altaicus C. A. Mey. (TA) is a common folk medicine in the Xinjiang area of China. In this study, we investigated the inhibitory effect
The ethanol extract of Chinese medicinal ants Polyrhachis lamelliden was evaluated for its analgesic and anti-inflammatory activities in mice. It was shown that the extract significantly inhibited acetic acid-induced writhing response and increased hot-plate pain threshold of mice at doses of 1.5
Streptococcus mutans is a pathogenic Gram-positive bacterium that is closely associated with dental caries and subsequent pulpal inflammation. Although lipoteichoic acid (LTA) is considered a major virulence factor of Gram-positive bacteria, little is known about the innate immunity to S. mutans
BACKGROUND
Caries and periodontal diseases remain as important diseases in the Brazilian population. One important pathogen associated with this situation is Streptococcus mutans and other important factor is this pathogen's ability to adhere firmly to the tooth surface leading to dental biofilm
The present study is aimed to evaluate antifilarial activity of Xylocarpus granatum (fruit from Andaman) against human lymphatic filarial parasite Brugia malayi in vivo. The in vitro antifilarial activity has already been reported earlier for this mangrove plant which has traditionally been used
BACKGROUND
Tradescantia albiflora (TA) Kunth (Commelinaceae) has been used for treating gout and hyperuricemia as folklore remedies in Taiwan. Therefore, it is worthwhile to study the effect of TA extracts on lowering uric acid activity. The hypouricemic effects of TA extracts on potassium oxonate
