BACKGROUND Malignant germ cell tumours are the most common malignant tumours in young men. They are histologically divided into seminomas and non-seminomas. Non-seminomas are further subdivided into embryonic carcinomas, yolk sac tumours, chorionic carcinomas, and teratomas. For the therapeutic management it is essential to differentiate between these histological subtypes. METHODS Investigat...

in this paper we propose and simulate a new heterostructure mesfet, called δ-doped ldd hmesfet. to improve carrier velocity in vicinity of the source in channel of gaas mesfet, one can replace source with alxga 1-x as. by increasing al content, discontinuity of hetero-interface could be increased. therefore, the velocity increases in the low field. however, increasing al mole fraction in excess...

Trust has been considered the "cement" of a society and is much studied in sociology and other social sciences. Most studies, however, have neglected one important aspect of trust: it involves an act of forgiving and showing tolerance toward another's failure. In this study, we refer to this concept as "generous trust" and examine the conditions under which generous trust becomes a more viable ...

Egg yolk is an essential ingredient for the preparation of a large variety of food emulsions. Thereby the emulsifying properties of egg yolk depend mainly on the physiological status of the two egg yolk fractions, granules (HDL) and plasma (LDL), which can be influenced by environmental conditions. Recent studies substantiate that a separate use of each fraction in innovative food products will...

The dimetallic [M(2)(bpy)(2)(NO(3))(2)](NO(3))(2) moieties (M = Pd(II) or Pt(II)) react preferentially at the pyrazolyl end of the pyridyl-pyrazole ligand, giving rise to dimetallic corners. Subsequently, the dimetallic corner building blocks featuring two pyridine donors are coordinated by monometallic [M(bpy)(NO(3))(2)] moieties (M = Pd(II) or Pt(II)) to form homo- or hetero-metallomacrocycles.

1 2 In teleost oocytes, yolk proteins (YP)-derived from the yolk precursors vitellogenins are 3 partially cleaved into free amino acids and small peptides during meiotic maturation prior to 4 ovulation. This process increases the osmotic pressure of the oocyte that drives its hydration 5 which is essential for the production of buoyant eggs by marine teleosts (pelagophil species). 6 However, th...
