Liposomes in silicosis investigations.

Investigations concerning the pre-radiological stage of silicosis.

Silicosis hazards in enamelling; a medical, technical, and experimental study.

Silicosis in enamel workers has been reported by Gaubatz (1940), Bruce (1945), Meures and Graf (1949), and Troisi (1952). One of Bruce's cases had third-stage silicosis (International Labour Office, 1930) and was completely disabled. A search of the literature, however, has revealed no further reports of advanced silicosis in such workers, even after long exposure to enamel dust. The cases desc...

Effect of bilayer flexibility and medium viscosity on separation of liposomes upon stagnation

Liposomes are widely used as drug delivery systems in different forms including osmotic pumps, infusion and IV injection. In spite of these, there is no data available about their behavior under convective flow (e.g. infusion or osmotic pumps) and upon stagnation in such drug delivery systems. As a part of a series of investigations in this area, the present study investigates the effects of vi...

Terpene-loaded liposomes and isopropyl myristate as chemical permeation enhancers toward liposomal gene delivery in lung cancer cells; A comparative study

Gene therapy is in its development stage as a novel method for cancer treatment. Liposomes look promising as gene delivery vectors; however, investigations have shown that these vesicles are not doing well in some cases. It was decided here to investigate the possibility of augmentation of liposomal gene delivery by chemical penetration enhancers.Cationic liposome containing antisense oligonucl...

The burden of silicosis, pulmonary tuberculosis and COPD among former Basotho goldminers.

BACKGROUND The burden of silicosis, pulmonary tuberculosis and COPD is described in 624 South African gold miners 18 months after cessation of work. METHODS This was a prevalence study. Questionnaires were administered, and spirometry, chest radiography, tuberculosis investigations, and urine HIV antibody assays were performed. RESULTS Attendance was 80.1% (624/779), mean age 49.4 years, an...
