Antibacterial and antifungal action of CTAB-containing silica nanoparticles against human pathogens.

New antibiotic agents are urgently needed worldwide to combat the increasing tolerance and resistance of pathogenic fungi and bacteria to current antimicrobials. Here, we looked at the antibacterial and antifungal effects of minor quantities of cetyltrimethylammonium bromide (CTAB), ca. 93.

α-Lipoic Acid as Adjunctive Treatment for Schizophrenia: A Randomized Double-Blind Study.

Background/purpose: There is evidence for low endogenous antioxidant levels and oxidative imbalance in patients with schizophrenia. A previous open-label study with α-lipoic acid (ALA), a potent antioxidant, improved patients' negative and cognitive symptoms and markers of lipid peroxidation. Here we report the results of a randomized double-blind, placebo-controlled study to verify the response of patients with schizophrenia to adjunctive treatment with ALA (100 mg/d) in a 4-month follow-up.

α-Lipoic Acid as Adjunctive Treatment for Schizophrenia: An Open-Label Trial.

Purpose/background: Accumulating evidence suggests an involvement of oxidative stress in the pathophysiology of schizophrenia. This offers a hypothesis-derived therapeutic approach to hinder oxidative damage and its clinical sequelae. α-Lipoic acid (ALA) is a powerful natural antioxidant indicated to treat diabetic neuropathy.

Identification and determination of the inulin content in the roots of the Northeast Brazilian species Pombalia calceolaria L.

A polysaccharide was extracted from the roots of Pombalia calceolaria, a plant used in folk medicine in Northeastern Brazil, by decoction followed by precipitation with methanol, yielding a concentration of 13.0% w/w, and purification with acetone. The molar mass peak was estimated to be 4.
