The protein folding problem is the problem of predicting the 3D structure of a protein when the linear sequence of aminoacids identifying it is known. In this paper we present a declarative implementation in Constrain & Generate style in CLP (FD) of the protein folding problem, for models based on face-centered cubes. We use information concerning secondary structure (and other heuristics) to s...

introduction and objective: zinc as the second trace element of the human body plays an important role in numerous functions. a large number of research studies have showed serum zinc deficiency and excess urinary excretion in patients with major beta thalassemia, but few studies revealed excess urinary zinc excretion in minor beta thalassemia and no study investigated serum zinc levels in this...

Malabsorption is frequently accompanied by skin symptoms, which are the most likely first manifestation of the disease. Skin lesions are mainly due to the deficiency of zinc, different vitamins, minerals, essential aminoacids, and other nutrients. The present paper demonstrates 3 patients with different types of skin symptoms primarily related to zinc deficiency, which occur in gastrointestinal...

CdS-coupled TiO2 nanocrystals were prepared by the microemulsion-mediated solvothermal method at pretty low temperatures. The semiconductor nanocrystals were modified with tyrosine, phenyl alanine, glysine and glutamate aminoacids and then were characterized by BET, SEM, EDX, XRD, UV–Vis spectroscopy, and FTIR analysis methods. The specific surface area and the average pore diameter ...
