background: the foramen magnum (fm) is an important landmark of the skull base and a transition zone between spine and skull as well as its close relationship to the brain and the spinal cord. so the fm has gained considerable interest due to its comparative anatomy, ontogeny, clinical, and animal breeding viewpoints. objectives: the aim of this study was to determine morphology and morphometry...

Genes affecting autoimmune type 1 diabetes susceptibility in the nonobese diabetic (NOD) mouse (Idd loci) have been mapped using a congenic strain breeding strategy. In the present study, we used a combination of BAC clone contig construction, polymorphism analysis of DNA from congenic strains, and sequence mining of the human orthologous region to generate an integrated map of the Idd10 region...

Cadmium (Cd), lead (Pb) and mercury (Hg) are toxic metals with increasing interest due to their tendency to bioaccumulate in fish tissue which may pose a threat to human health via fish consumption. This review of the recent literature on Cd, Pb, Hg levels summarizes data of fish biomonitoring studies in the Mediterranean Sea in order to determine potential risks due to dietary intake of metals...

8 weeks feeding trial was undertaken to evaluate soybean cheese residue (SCR) with 29 old layers. SCR incorporated at 0, 5, 10, 15 and 20 % in diets T1, T2, T3, T4, T5 respectively. Ninety (90) twenty-nine week birds were used for the experiment. The allocated five a Completely Randomized Design (CRD). Each treatment had eighteen (18) such that each replicate six (6) birds. There no observed si...

There are two hypotheses on egg maturation in the invasive chestnut gall wasp, Dryocosmus kuriphilus Yasumatsu (Hymenoptera: Cynipidae). That it is pro-ovigenic (most or all of its potential lifetime complement mature upon emergence) facultatively synovigenic (not eggs fully developed emergence and may be resorbed when suitable hosts absent). These were tested by determining effects adult age f...

Cardiovascular diseases rank as America's primary killer, claiming the lives of over 41% of more than 2.4 million Americans. One of the main reasons for this high death toll is the severe lack of effective imaging techniques for screening, early detection and localization of an abnormality detected on the electrocardiogram (ECG). The two most widely used imaging techniques in the clinic are CT ...

Despite the beneficial aspect of fish consumption, bioaccumulation toxic metals such as arsenic (As) and mercury (Hg) can enhance health risk for consumers. Arsenic Hg concentrations were measured in edible tissue two targeted organs, namely gill liver longtail tuna species (Thunnus tonggol) from Terengganu waters, including Kuala Besut, Terengganu, Dungun Kemaman. The concentration As analysed...

The aim of the present work conducted at the Refugio de Vida Silvestre Bahía Samborombón is to analyse the most relevant aspects of the fecundity of Chasmagnathus granulatus and Uca uruguayensis. Samplings were carried out from March 2001 to February 2003. Ovigerous females of U. uruguayensis (N = 13) and C. granulatus (N = 25) were found during spring and summer, their sizes (CW) varied from 9...
