Purpose: To examine the relationship between substance dependency and personality disorders.   Materials and Methods: Ninety eight patients with substance dependency who had referred   to a psychiatry and substance rehabilitation center in Tehran took part in this study. Data were   collected using questionnaire and a semi-structured interview. Participants were examined for   conduct and ant...

Crystalline, yet smooth, sphere-like morphologies of small molecular compounds are desirable in a wide range of applications but are very challenging to obtain using common growth techniques, where either amorphous films or faceted crystallites are the norm. Here we show solvent-free, guard flow-assisted organic vapour jet printing of non-faceted, crystalline microspheroids of archetypal small ...

Colloidal mesoporous silica nanoparticles less than 20 nm in diameter are prepared by dialysis; this simple surfactant removal route can avoid aggregation by sedimentation-redispersion and remove cationic surfactants while retaining the original colloidal state, which is applicable to the preparation of primary nanoparticles carrying a functional organic substance.

With the rapid development of water quality analysis technology, endocrine disruptors (ECDs) such as residual pharmaceuticals including antibiotics are continuously detected from the drinking water sources of Korea which are mostly rivers. Due to the recent abnormal climate, the average temperature of river and lake water has been increased, and substances having taste and odours because of alg...

This paper studies the impact of the location of a drug substance on the physicochemical and mechanical properties of two types of calcium phosphate granules loaded with seven different contents of ibuprofen, ranging from 1.75% to 46%. These implantable agglomerates were produced by either low or high shear granulation. Unloaded Mi-Pro pellets presented higher sphericity and mechanical properti...

An interaction is taken to be the situation in which the administration of a drug or substance induces changes in the pharmacokinetics of another simultaneously administered drug – either increasing or decreasing the plasma concentration of the latter, and thus giving rise to the possibility of adverse reactions [1]. According to the primarily responsible pharmacological mechanism, H 1 antihist...

The hemotoxin of streptococcus is a labile substance affected by centrifugation or shaking. It is adsorbed by various organic and inorganic substances. Hemotoxin is produced within a wide range of hydrogen ion concentrations. It is neither in nor on the bacterial cell but is free in the culture medium. It is probably not an enzyme. There are at least two substances which are essential to the me...

The present report deals with the identification of a new bacterial substance which was first recognized as a result of its reactivity with certain streptococcal antisera. Extracts of Groups A to G streptococci, as well as those of various other Gram-positive bacteria, give strong precipitin reactions with these antisera, indicating that the substance is widely distributed in the microbial worl...
