Current Clinical Concepts: Rehabilitation of Thoracic Outlet Syndrome.

Thoracic outlet syndrome (TOS) involves an inconsistent set of symptoms that provides a challenge for medical providers to treat. Three categories of TOS are neurogenic, arterial, and venous. A combination of symptoms can occur and are most seen in overhead athletes.

Using entropies of reaction to predict changes in protein stability: tyrosine-67-phenylalanine variants of rat cytochrome c and yeast Iso-1 cytochromes c.

Using the voltammetric method of square-wave voltammetry, a direct electrochemical examination was made of the wild type and Tyr67Phe mutant of both rat cytochrome c and yeast iso-1-cytochrome c. In addition to determining the equilibrium reduction potential (E0') for each cytochrome, the entropy of reaction, deltaS0'(Rxn)(deltaS0'(Rxn) = S0'(Red) - S0'(Ox)), for the reduction process was determined via the non-isothermal method. Having determined deltaS0'(Rxn) and E0', deltaH0' was calculated.

[Eating and drinking in patients with Alzheimer dementia. A study of interactions].

Eating and drinking become difficult for people afflicted with dementia. We have therefore analysed the mealtime constellation in five cases of institutionalised people suffering from Alzheimer using video in an open technique. The process of eating and drinking entailed intensive interaction between patients and their nurses.

Analysis of pesticide residues in Peninsular Malaysian waterways.

The use of organochlorine pesticides has caused concern due to their effects on human health and the Malaysian aquatic ecosystem, particularly so in view of their persistent and bioaccumulative properties. Since the extent of organochlorine pesticide pollution in Malaysian waterways is unknown except for isolated instances, a systematic survey has now been carried out. Water samples from various rivers were extracted, cleaned up with Florisil and analysed for the individual organochlorine pesticides by gas chromatography (GC) with an electron capture detector (ECD).
