Avian ketocarotenoid pigments occur in both the red retinal oil droplets that contribute to colour vision and bright red coloration used in signalling. Turtles are the only other tetrapods with red retinal oil droplets, and some also display red carotenoid-based coloration. Recently, the CYP2J19 gene was strongly implicated in ketocarotenoid synthesis in birds. Here, we investigate CYP2J19 evol...

We have computed 8, 10, and 12 Gyr isochrones and physically consistent models of zero-age red horizontal branch stars for stellar masses between 0.55 and 1.3 M , all at [Fe/H] = +0:15. Comparison to the NGC 6791 BVI photometry of Ka lu_ zny & Udalski (1992, Acta Astron., 42, 29) and Montgomery, Janes & Phelps (1994, AJ, 108, 585) yields an age of 10:0 0:5 Gyr at an apparent distance modulus 13...

Pericarditis is a rare manifestation of tuberculosis (Tb) in children. A 14-yr-old Korean boy presented with cardiac tamponade during treatment of pulmonary tuberculosis. He developed worsening anemia and persistent fever in spite of anti-tuberculosis medications. Echocardiography found free floating multiple discoid masses in the pericardial effusion. The masses and exudates were removed by pe...

We show that the soft SUSY breaking mass terms may have infra-red stable fixed points at which they are related to the gaugino masses and argue that in a generic unification these masses should lie close to their fixed points. We consider the implications for the family dependence of squark and slepton masses and the related flavour changing neutral currents and determine conditions under which...

Pathogenic T. pallidum cells possess and extracellular layer when observed in vivo and in vitro after exposure to ruthenium-red. The extracellular layer is partially removed from a pre-fixed cell by repeated washing in vitro. Non-pathogenic treponemes examined in this study do not possess an extracellular layer. It is hoped that the data presented herein will cause our colleagues to take anothe...

Introduction: Breast cancer tumors are 3-13 times stiffer than normal tissue [1]. The use of strain-encoded (SENC) MRI was proposed in [2] to detect masses by measuring strain, which is inversely proportional to stiffness. The use of strain imaging of breast lesions would provide a new measure for clinical diagnosis between benign and malignant tissue. Previously in [2], we have shown that SENC...
