We report the spatiotemporal control of a 3D coculture by combining photocurable and chemically degradable hydrogels for coculture of embryonic stem (ES) cells with HepG2 cells. ES cells were encapsulated in micropatterned photocurable poly(ethylene glycol) (PEG) hydrogels. The cell-laden PEG hydrogels were then encapsulated in calcium-alginate (Ca-Alg) hydrogel containing HepG2 cells. The ES c...

1PM: Oleg Viro (Stony Brook). Multifields (fields with multivalued addition), base fields of tropical geometries. Abstract:In many classical number sets (e.g., complex numbers, real numbers and non-negative real numbers), there are remarkable structures of multifield. Replacing the tropical max-plus semifield in the foundations of tropical geometry by a multifield simplifies the structure of tr...

Let 1 ≤ m ≤ n be integers with m|n and Alg n,m the class of central simple algebras of degree n and exponent dividing m. In this paper, we find upper bounds for the essential (2)-dimension of Alg n,2 . Moreover, we find a stronger upper bound for the essential 2-dimension of Alg n,2 over a field F of char(F ) 6= 2. As a result, we show that ed2(Alg16,2) = 24 over a field F of char(F ) 6= 2.

Gametogenesis is a thermosensitive process in numerous metazoans, ranging from worms to man. In Caenorhabditis elegans, a variety of RNA-binding proteins that associate with germ-line nuage (P granules), including the Piwi-clade argonaute PRG-1, have been implicated in maintaining fertility at elevated temperature. Here we describe the role of two AGO-class paralogs, alg-3 (T22B3.2) and alg-4 (...

The competitive analysis of an algorithm Alg consists of two separate steps. First, we show that for an arbitrary problem instance, the result of Alg is asymptotically at most a factor r worse than the the optimal offline result. This yields an upper bound on Alg’s result, that is costAlg ≤ r · costOpt + c. If the task is to show that Alg is constant-competitive for a constant r, then we are do...

conclusions algino-pectinate mucoadhesive formulations exhibited promising properties of a sustained release form for piroxicam and provided distinct tissue protection in stomach. objective the purpose of this research was to decrease gastric side effects of piroxicam by formulating microspheres of alginate and algino-pectinate beads of the drug. materials and methods ionotropic gelation was us...

This study aimed to obtain site-specific and controlled drug release particulate systems. Some particulates were prepared using different concentrations of sodium alginate (Na-Alg) alone and others were formulated using different proportions of Na-Alg with hydroxypropyl methylcellulose (HPMC) stearoxy ether (60M viscosity grade), a hydrophobic form of conventional HPMC, using diclofenac potassi...

A variety V has an alg-universal n-expansion if the addition of n nullary operations to algebras from V produces an alg-universal category. It is proved that any semigroup variety V containing a semigroup that is neither an inflation of a completely simple semigroup nor an inflation of a semilattice of groups has an alg-universal 3-expansion. We say that a variety V is var-relatively alg-univer...

Although selenium nanoparticles (Nano Se) have gained attention for their anti-cancer and antioxidant activity, this nanomaterial's antimicrobial activity also has great potential. The aim of study was to synthesize Nano Se edible coating solution through gamma irradiation technique with a bio-stabilizer sodium alginate (Na-alg.), which is an ingredient commonly used in food preservation. Dynam...
