Introduction: In this study, antidiabetic activity of 6% curcumin and chi-alg-encapsulated 6% curcumin isolated from the curumina longa (commonly called as turmeric) mother rhizome were evaluated and compared. Materials and Methods: The 6% curcumin-chi-alg encapsulated nanoparticles were prepared and characterized using scanning electron microscope and Fourier transform infrared. The antidiabet...

The progress of medical therapies, which rely on the transplantation of microencapsulated living cells, depends on the quality of the encapsulating material. Such material has to be biocompatible, and the microencapsulation process must be simple and not harm the cells. Alginate-poly(ethylene glycol) hybrid microspheres (alg-PEG-M) were produced by combining ionotropic gelation of sodium algina...

Mucoadhesive polymer-coated pellets containing metformin hydrochloride were prepared by the powder-layering technique using a centrifugal fluidizing (CF)-granulator. Four high-viscosity polymers were applied to make the pellets: 1) hydroxymethylcellulose (HPMC), 2) sodium alginate (Na-Alg), 3) HPMC/Carbopol, and 4) sodium carboxylmethylcellulose (Na-CMC). The physical crushing test, mucoadhesiv...

Blind signal extraction, a hot issue in the field of communication signal processing, aims to retrieve the sources through the optimization of contrast functions. Many contrasts based on higher-order statistics such as kurtosis, usually behave sensitive to outliers. Thus, to achieve robust results, nonlinear functions are utilized as contrasts to approximate the negentropy criterion, which is a...

Consider a trader who exchanges one dollar into yen and assume that the exchange rate fluctuates within the interval [m,M ]. The game ends without advance notice, then the trader is forced to exchange all the remaining dollars at the minimum rate m. El-Yaniv et al. presented the optimal worst-case threat-based strategy for this game [EFKT01]. In this paper, under the assumption that the distrib...

In the script there is a definition for the competitiveness of an algorithm. However, this definition only holds if we want to evaluate an algorithm by means of its costs. Sometimes, we want to compare algorithms regarding their benefit rather than their costs. In this case, we have to be a bit careful with the definition of a c-competitive algorithm. We say that an algorithm Alg is c-competiti...

The cytoplasmic protein Alix/AIP1 (ALG-2 interacting protein X) is involved in cell death through mechanisms which remain unclear but require its binding partner ALG-2 (apoptosis-linked gene-2). The latter was defined as a regulator of calcium-induced apoptosis following endoplasmic reticulum (ER) stress. We show here that Alix is also a critical component of caspase 9 activation and apoptosis ...

Notation. We will use some notation [mostly] from the class. A is the set of arms, T is the time horizon, K is the number of arms. At each round t, at is the arm chosen by the algorithm, and ct(a) is the cost of arm a. Total cost of arm a is cost(a) = ∑T t=1 ct(a). The best total cost for a subset S of arms is defined as cost∗(S) = infa∈S cost(a). The total cost of an algorithm ALG is cost(ALG)...
