AIM The experiment was carried out to evaluate different external and internal egg quality traits and to figure out their mode of inheritance from a set of hierarchically classified data. MATERIALS AND METHODS The data collected from 548 progenies (1 egg from each progeny) of 282 dams mated to 47 sires (1 sire mated to 6 dams) of a White Leghorn flock were used in the present study. Phenotypi...

Nearly monodispersed yolk-type Au@Fe3O4@C nanospheres with hollow cores of 50 nm in diameter were prepared through coating Au@SiO2 nanoparticles with Fe3O4@C double layers, followed by dissolving SiO2. The cytotoxicity of the nanospheres was evaluated by MTT assay, demonstrating a high biocompatibility. The yolk-type nanospheres show a high DOX loading content of 1237 mg g(-1). The coexistence ...

BACKGROUND Buddlejasaponin IV (BS-IV), a triterpene saponin isolated from Pleurospermum kamtschaticum HOFFMANN (Umbelliferae), is known to have potent anti-inflammatory activity and cytotoxicity against diverse cancer cell lines. In the present study, we attempted to verify whether BS-IV could inhibit cell growth, and induce cell cycle arrest and apoptosis in highly invasive YD-10B human oral s...

Community-based partnerships (CBPs) focused on youth development (YD) have the potential to improve public health outcomes. These partnerships also present opportunities for the design and implementation of innovative, community-level change strategies, which ultimately may result in new capacities for positive YD. Evaluation-driven learning and improvement frameworks facilitate the achievement...

The Younger Dryas (YD) cold interval is one of the most abrupt climate events of Earth's recent history. The origin of this rapid, severe cooling episode is still widely debated, but it was probably triggered by a large freshwater influx to the North Atlantic resulting in disruption of the Atlantic Meridional Overturning Circulation. The YD termination, despite having been even more abrupt than...

In this paper we introduce a Jones-type invariant for singular knots, using a Markov trace on the Yokonuma–Hecke algebras Yd,n(u) and the theory of singular braids. The Yokonuma–Hecke algebras have a natural topological interpretation in the context of framed knots. Yet, we show that there is a homomorphism of the singular braid monoid SBn into the algebra Yd,n(u). Surprisingly, the trace does ...

The yolk sac of human embryos from the 5th to 7th week of gestation was first revealed under the scanning electron microscope (SEM) with complementary observations under the transmission electron microscope (TEM). The inner and outer surfaces of the human yolk sac basically showed profiles similar to those of other mammalian yolk sacs reported by previous workers. The free surface of the endode...

Study of living frog oocytes with the phase microscope has shown that the early yolk appears in two forms. One of these, the protein yolk, consists of thin, dense, plate-like bodies which in face view are almost always regular hexagons. The other form, the fatty yolk, occurs as clusters of globules of varying sizes. The plate-like bodies occur both singly and in clusters. As the oocytes mature ...

Abstract. In the European Alps, Younger Dryas (YD) was characterised by last major glacier advance, with equilibrium line altitudes being ? 220 to 290 m lower than during Little Ice Age, and also development of rock glaciers. Dating these geomorphic features, however, is associated substantial uncertainties, leading considerable ambiguities regarding internal structure this stadial, which most ...
