The genome of the fission yeast Schizosaccharomyces pombe has been sequenced, bringing the number of sequenced eukaryotic genomes to six. Analysis of the sequence predicts only 4824 protein coding genes, the smallest number yet recorded for a free-living eukaryote.

Size matters, particularly in demonstrations. A demonstration is in support of a movement or a cause. The movement has a number of sympathisers. The perceived number of sympathisers is important. If it is seen to be large, then it becomes easier to recruit others to the cause, and to persuade inactive sympathisers to join the demonstrations. Also, if the movement numbers are large then it is mo...

Premenstrual syndrome (PMS) affects up to 80% of women, often leading to significant personal, social and economic costs. When apparently maladaptive states are widespread, they sometimes confer a hidden advantage, or did so in our evolutionary past. We suggest that PMS had a selective advantage because it increased the chance that infertile pair bonds would dissolve, thus improving the reprodu...

We recognise that Stegosaurus exhibited exterior chirality and could, therefore, have assumed either of two distinct, mirror-image forms. Our preliminary investigations suggest that both existed. Stegosaurus’s exterior chirality raises new questions such as the validity of well-known exhibits whilst offering new insights into long-standing questions such as the function of the plates. We inform...

background and aim: recently some evidence has been presented that periodontal disease is associated with an increased risk of cardiovascular disease. the hypothesis of this study is that periodontitis may be associated with elevated blood lipid levels, a known risk factor for atherosclerotic disease. methods & materials: the levels of plasma lipids was measured in 40 subjects with chronic peri...

Relaxation times (T(1) and T(2)) of the bone marrow protons and trabecular bone volume fraction (TBVF) in the calcaneus were measured for 100 female volunteers using a compact MRI system at 0.2 T field strength. The speed of sound (SOS) through the calcaneus was measured also for the same subjects using a quantitative ultrasound system. Both relaxation times were found to have positive correlat...

PURPOSE To determine the activity of seminal plasma catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPX) and their relationship with malondialdehyde (MDA), as a marker of lipid peroxidation, content of spermatozoa and seminal plasma in normozoospermic and asthenozoospermic males. MATERIALS AND METHODS Semen samples were obtained from 15 normozoospermic and 30 asthenozoo...

background: information regarding serum biochemicalprofile can reflect cardiovascular performance in animals.although studies have evaluated the inter-relationship amongcardiovascular biomarkers in animals and human beings, thereare no reports of such a probable relationship in camelids.objectives: the aim of the present study was to provide dataon the correlations among cardiovascular biomarke...
