BACKGROUND Tannery workers are at considerable risk of developing occupational contact dermatitis. Occupational skin diseases in tannery workers in newly industrialized countries have been reported, but neither the prevalence of occupational allergic contact dermatitis nor the skin-sensitizing agents were specifically examined in those studies. OBJECTIVES To assess the prevalence of occupatio...
In Parkinson's disease (PD) depletion of dopamine in the nigro-striatal pathway is a main pathological hallmark that requires continuous and focal restoration. Current predominant treatment with intermittent oral administration of its precursor, Levodopa (l-dopa), remains the gold standard but pharmacological drawbacks trigger motor fluctuations and dyskinesia. Continuous intracerebroventricula...
Apomorphine in solution undergoes rapid autoxidation, producing greenish colored solutions, making it difficult to formulate as a stable pharmaceutical solution. To identify the optimum antioxidant agent/combination for apomorphine solution, a high performance liquid chromatography assay was used to study the stability of 50 μg/mL apomorphine HCI in 0.1% L-ascorbic acid (AA), 0.1% sodium metabi...
Sickle cell disease (SCD) is a genetic blood disorder that affects the shape and transportation of red blood cells (RBCs) in blood vessels, leading to various clinical complications. Many drugs that are available for treating the disease are insufficiently effective, toxic, or too expensive. Therefore, there is a pressing need for safe, effective, and inexpensive therapeutic agents from indigen...

Objective. Near-infrared spectroscopy (NIRS) measurements of tissue oxygen saturation (StO2) are useful for the assessment of skeletal muscle perfusion and function during exercise, however, they are influenced by overlying skin and adipose tissue. This study explored the extent and nature of the influence of adipose tissue thickness (ATT) on StO2. Approach. NIR spatially resolved spectroscopy ...
To assess the effects on bronchial responsiveness of nebulized glutathione (GSH), one of the most efficient scavengers of oxidant substances in the airways, we studied eight patients with mild asthma (FEV1, 88 +/- 11% predicted [SD]) in a randomized, double-blind, cross-over, placebo-controlled fashion. Bronchial challenge was measured using both FEV1 and total pulmonary resistance (Rrs) by the...
Polyphenol oxidases are found both in prokaryotic and eukaryotic microorganisms, in mammals, invertebrates and plants. Most plants have multiple forms of PPO. The more recent articles regarding the polyphenol oxidases from different plants are reviewed. The main characteristics considered were the sources, structure and properties of polyphenol oxidase (PPO) as well as the inhibitors of this en...
results sickle cells were observed among 20% of subjects with the dilution of 1:50 and 70% of subjects with the dilution of 1:100. mean percentage of sickle red cells with dilutions of 1:50, 1:100 and 1:200 were 3.75%, 25.75% and 43.0%, respectively. conclusions it is suggested that c. fistula may protect rbc against sickling, in hypoxic conditions, in individuals with hbs gene defect. objectiv...
