In the setting known as DLOGTIME-uniformity, the fundamental complexity classes AC ⊂ ACC ⊆ TC ⊆ NC have several robust characterizations. In this paper we refine uniformity further and examine the impact of these refinements on NC and its subclasses. When applied to the logarithmic circuit depth characterization of NC, some refinements leave NC unchanged while others collapse NC to NC. Thus we ...

Human Immunodeficiency Virus type 1 (HIV-1) is a retrovirus that causes acquired immunodeficiency syndrome (AIDS). HIV-1 Tat protein upregulates transcriptional transactivation. The nucleocapsid protein NC of HIV-1 is a component of virion and plays a key role in genome packaging. Herein, we have demonstrated the interaction between NC and Tat by means of a yeast two-hybrid assay, GST pull-down...

We investigate properties of the color space of SU(Nc) gauge theories in the limit of small number of colors (Nc → 0) and large number of flavors. More generally, we introduce a rescaling of αs and nf which assigns a finite limit to colored quantities as Nc → 0, which reproduces their known large-Nc limit, and which expresses them as an analytic function of N2 c for arbitrary value of Nc. The v...

Neural crest (NC) cells are multipotent progenitors that form at the neural plate border, undergo epithelial-mesenchymal transition and migrate to diverse locations in vertebrate embryos to give rise to many cell types. Multiple signaling factors, including Wnt proteins, operate during early embryonic development to induce the NC cell fate. Whereas the requirement for the Wnt/β-catenin pathway ...

This study aims to determine the effect of red dragon (Hylocereus polyrhizus) fruit peel extract (RDFPE) on spermatozoa motility and viability hypercholesterolemic rats (Rattus norvegicus) as a model. Twenty male were randomly divided into negative control (NC), positive (PC), treatment 1 (T1), 2 (T2), 3 (T3) groups. All given mL high cholesterol feed orally every day for 28 days. On day-15, al...

in the past decades, environmental pollution caused by plastic packing materials, restrictions of petroleum resources and their high price attracted many researchers to produce biodegradable packaging materials. poor mechanic properties and high water vapor permeability are two main defects of biodegradable polymers. nanotechnology is a modification method in this case. in the current study, th...

in this study 93 hirsute females (ferryman and gallway score > 8) referred to institute of endocrinology & metabolism and office were assessed. baseline testosterone (tes), dehydroepiandrosterane sulfate (dhea-so4). follicular stimulating hormone (fsh). leuteinizing hormone (lh), prolactin (prl), thyroid stimulating hormone (tsh), baseline 17 hydroxyprogesterone (17 ohp) and in some cases acth ...
