1. Urine screening by Seldi-Tof, followed by biomarker identification, in a Brazilian cohort of patients with Renal Cell Carcinoma (RCC)
Purpose To screen proteins/peptides in urine of Renal Cell Carcinoma (RCC) patients by SELDI-TOF (Surface Enhanced Laser Desorption Ionization - Time of Flight) in search of possible biomarkers. Material and Methods Sixty-one urines samples from Clear Cell RCC and Papillary RCC were compared to 29 samples of control urine on CM10 chip. Mass analysis was p

2. Análise fractal da vascularização da membrana vitelina de embriões de codornas japonesas (Coturnix japonica)submetidas a dietas enriquecidas com ácidos graxos poliinsaturados em diferentes concentrações.
O objetivo deste estudo foi investigar o efeito de diferentes dietas sobre o perfil lipídico sérico de codornas japonesas e sobre o crescimento vascular na membrana vitelina (MV) dos embriões das aves suplementadas com óleo de peixe e óleo de soja. Foram utilizadas 80 codornas, distribuídas em cinco tratamentos denominados Dieta Controle (DC), Óleo de

3. Production and reproduction of egg- and meat-type quails reared in different group sizes
Egg- and meat-type quails were reared in groups of different sizes with a fixed female-to-male ratio of 2 to 1 and an area of 158 cm² per bird. The aim was to investigate the influence of group size on quail production and reproductive variables. To this end, 360 quails (180 meat and 180 egg-type quails) were assigned in a completely randomized experimental

4. Placentation in rock cavies, Kerodon rupestris (Wied, 1820) / Placentação em mocós, Kerodon rupestris Wied, 1820
Placentation studies of fourteen rock cavy females in different gestation phases were conducted. Females were pre-anesthetized associating ketamine chloridrate (15mg/kg) and midazolan (1mg/kg). Soon afterwards, they were anesthetized by isoflurane inhalation in association with oxygen at 100% saturation. After anesthesia, the surgery allowed to exhibit fetal

5. Isolation and chromosomal location of putative vitelline membrane genes in Drosophila melanogaster.
cDNA clones for two Drosophila vitelline membrane genes have been identified on the basis of: (i) stage and tissue specificity of transcription and (ii) size and amino acid content of the translation product. Cross-hybridization data suggest that DmcMM99 and DmcMM115 are members of a multi-gene family which includes at least three members, all of which resid

6. Crystal structure of vitelline membrane outer layer protein I (VMO-I): a folding motif with homologous Greek key structures related by an internal three-fold symmetry.
The crystal structure of vitelline membrane outer layer protein I (VMO-I), which is isolated from the vitelline membrane outer layer of hen's eggs, has been determined by the multiple isomorphous replacement method and refined to an R-factor of 18.8% at 2.2 A resolution. The main chain folds into an unusual structure that consists of three beta-sheets formin

7. Gallus domestica Yolk (Vitelline) Membrane Use for In Vitro Microbial Adherence Studies
The yolk membrane of unfertilized eggs (Gallus domestica) was isolated, washed, placed onto a glass holder, and utilized as an in vitro membrane model to study yeast attachment.

8. The abalone egg vitelline envelope receptor for sperm lysin is a giant multivalent molecule
Abalone sperm lysin is a 16-kDa acrosomal protein, which nonenzymatically and species selectively creates a hole in the egg vitelline envelope (VE) through which the sperm passes to reach the egg cell membrane. The crystal structures of both monomeric and dimeric lysins have been solved and the sequences of lysins from 20 abalone species have been determined

9. Species-specific sequences of abalone lysin, the sperm protein that creates a hole in the egg envelope.
Abalone eggs are contained within a rigid, elevated vitelline envelope through which the sperm must pass before reaching the egg cell membrane. Abalone spermatozoa possess an acrosomal protein called lysin that creates a hole in the egg vitelline envelope by a nonenzymatic mechanism. Lysins from two species of abalone, termed pink and red, which share the sa

10. Follicle cell proteasome activity and acid extract from the egg vitelline coat prompt the onset of self-sterility in Ciona intestinalis oocytes
In the hermaphrodite ascidian Ciona intestinalis, the egg vitelline coat (VC) controls gamete self–nonself discrimination. Oocytes, after germinal vesicle breakdown, can be fertilized by both self and nonself sperm. However, a barrier to fertilization by self sperm progressively develops in the VC in the 3 hours after germinal vesicle breakdown. During thi

11. The morphology of the haemopoietic cells of the yolk sac in mice with particular reference to nucleolar changes.
Nucleolar changes of haemopoietic cells during the development of the mouse yolk sac blood islands were qualitatively examined by light and electron microscopy. Haemopoiesis in the yolk sac begins at seven days of gestation and, after the formation of vitelline vessels, erythropoiesis appears to be active at ten days. At 7-8 days of gestation, angioblasts ha

12. Turning on of activities in unfertilized sea urchin eggs: correlation with changes of the surface.
Unfertilized sea urchin eggs exposed to low concentrations of ammonia enter into a number of activities which normally appear after fertilization. It is shown that the effects are attributable to ammonia, rather than to NH4+ ions of elevated pH. The same effects are obtained by exposure to isotonic urea and to glycerol at very low ionic strengths. All treatm
