1. Studies on the level of substance P and calcitonin gene-related peptide in cerebrospinal fluid of pregnant women and patients with chronic pain and in rat brain after spinal cord injury : Special reference to analytical aspects of neuropeptides
Abstract : Substance P (SP) and calcitonin gene-related peptide (CGRP) are sensory peptides known to be involved innociception and inflammatory processes. It is well demonstrated that the two peptides can be released from spinal cord neurons during inflammation and chronic pain induced by peripheral nerve injury. READ MORE

2. Elimination of caffeine metabolites in man
Abstract : Plasma, saliva and urinary caffeine (CA), paraxanthine (PX), theobromine (TB), theophylline (TP) and their metabolites were, after separation into fractions by reversed-phase high-performance liquid chromatography (HPLC), quantitated by capillary electrophoresis (CE). In healthy adults, 96% of the total amount of excreted compounds derived from CA were dimethylxanthines (DMXs) and metabolites, the remainder 4% being nonmetabolized CA and its non-demethylated urate.

3. Consumption and loss of commercial stabilisers in polyethylene exposed to different natural environments
Abstract : A procedure for the extraction and analysis of commercialstabilisers in low density and medium density polyethylene(LDPE and MDPE) films was developed and used to study theconsumption of stabilisers in polymers exposed to differentnatural environments. An ultrasonic technique was applied toextract HALS-3 (Chimassorb 944) from LDPE film and antioxidants(Irganox 1010 and Irgafos 168) from MDPE film. READ MORE
