In the present paper, attention is paid to synthesis and investigation swelling behavior of a superabsorbent hydrogel composite based on Pectin (Pec) and polyacrylonitrile (PAN) in the presence Kaolin powder. The physical mixture of Pec, Kaolin and PAN were hydrolyzed by NaOH solution to yield H-Pec-poly (sodium acrylate-co-acrylamide)/Kaolin superabsorbent hydrogel composite. A proposed mechan...

A perivascular epithelioid cell tumor (PEComa) is a peculiar growth defined as a mesenchymal tumor composed of histologically and immunohistochemically distinct perivascular epithelioid cells (PECs). Because neither normal counterparts nor precursor lesions of PEComa have been identified, we examined minute PEC nests, ranged from 0.8 mm to 10 mm, to investigate the possible origin of the PEComa...

The space within the Great pyramid and its smaller replicas are believed to have healing powers due to the presence of cosmic and earth’s radiations which are influenced by seasons. The present study was done to determine if seasonal variations influence pyramid-mediated decrease in neuroendocrine and oxidative stress in rats. The experiment was conducted in Manipal, India (74o53’E, 12o55’N), t...

A systematic approach was developed to understand, in-depth, the mechanisms involved during the inactivation of bacterial cells using photoelectrocatalytic (PEC) processes with Escherichia coli K-12 as the model microorganism. The bacterial cells were found to be inactivated and decomposed primarily due to attack from photogenerated H2O2. Extracellular reactive oxygen species (ROSs), such as H2...

Intraocular inoculation of antigens induces anterior chamber-associated immune deviation (ACAID), which is mediated by development of regulatory T cells in response to antigen-presenting cells (APC) pre-conditioned by intraocular transforming growth factor-beta (TGF-beta). In this study, we examined the involvement of T-cell co-stimulatory molecules in this process. To mimic the intraocular APC...

The cortical projections to the caudal part of the superior parietal lobule (area PEc) were studied in 6 cynomolgus monkeys using fluorescence tracers. Significant numbers of labeled cells were found in a restricted network of parietal, mesial, and frontal areas. Quantitative analysis demonstrated that approximately 30% of the total projection neurons originated in the adjacent areas of the dor...

Corrosion has an important effect on the structural integrity of aging aircraft components, and an automatic and effective method of corrosion detection and classification can help to ensure the safe operation of a transportation system. Pulsed eddy current (PEC) has been shown to effectively characterize hidden corrosion in aircraft fuselage lap joints. However, two noise sources in the form o...

INTRODUCTION Pharmaceutical residues and other organic wastewater contaminants (OWC) have been shown to survive conventional water-treatment processes and persist in potable water supplies. OBJECTIVE To estimate the geographical distribution of the Predicted Environmental Concentration (PEC) of selected drugs prescribed by office based physicians in the United States (US), after non-metaboliz...

Polyelectrolyte complexes (PECs) were prepared by structural uniform and strongly charged cationic and anionic modified alternating maleic anhydride copolymers. The hydrophobicity of the polyelectrolytes was changed by the comonomers (ethylene, isobutylene and styrene). Additionally, the n−/n+ ratio of the molar charges of the polyelectrolytes and the procedure of formation were varied. The col...

In recent years, there has been an increasing interest in the design of biomaterials for cartilage tissue engineering. This type of materials must meet several requirements. In this study, we apply ultrasound to prepare a compatibilized blend of polyelectrolyte complexes (PEC) based on carboxymethyl cellulose (CMC) and chitosan (CHI), in order to improve stability and mechanical properties thro...
