Peritoneal exudate cells (PEC) from C57BL/6 mice were collected on different days following an i.p. injection of Adriamycin (10 mg/kg) as free drug (ADM) or encapsulated in multilamellar liposomes (ADM/Lip). Macrophages harvested from mice at various times (Days 4-14) after either drug treatment were responsive to in vitro lipopolysaccharide induction of tumoricidal activity, maximum response b...

This experiment was conducted to study the effects of various amounts of treated sunflower meal (SFM) with extracted tannins from pistachio hulls on in vitro gas production and ruminal fermentation in ruminants. The SFM was treated with pistachio extract concentrate (PEC), which contained 111.40 g kg-1 total phenol and 71.30 g kg-1 total tannin per dry matter of e...

Erwinia chrysanthemi synthesizes and secretes pectate lyases that attack components of the plant cell wall and, therefore, play a major role in the pathogenesis of soft rot disease. We isolated a new mutant (designated pec-1), by Tn5 mutagenesis, that displays weak pectate lyase production and decreased motility and mucoidicity. Maceration and pathogenicity tests done on different plant organs ...

'Real-world' contaminant exposure of sediment-dwelling biota is typically long-term, low-level and to multiple pollutants. However, sediment quality guidelines, designed to protect these organisms, relate only to single contaminants. This study uses radiometrically dated sediment cores from 7 English lakes with varying contamination histories to reconstruct temporal changes in likely risk to bi...

BACKGROUND AND AIM Percutaneous endoscopic colostomy provides an alternative management option for patients with recurrent sigmoid volvulus who are considered too high risk to undergo surgery. We reviewed the literature to assess whether the National Institute for Health and Clinical Excellence guidelines published in 2006 supporting the use of percutaneous endoscopic colostomy are still valid....

Perivascular epithelioid cell tumor (PEC-oma) is a rare mesenchymal neoplasm. Literature reports more than 100 cases of PEC-oma, a third of which is of uterine or uterine retroperitoneum origin. The case of a 59-year-old woman presented here is, to the best of our knowledge, the first described fast uterine PEC-oma recurrence of the tumor of the gastrointestinal tract origin. In this text the a...

Solar-driven photoelectrochemical (PEC) water splitting is a promising technology for sustainable hydrogen production, which relies on the development of efficient and stable photoanodes oxidation reaction. The thickness microstructure semiconductor films are generally crucial to their PEC properties. Herein, three-dimensional (3D) interconnected nanoporous Ta3N5 film with controlled were succe...

Human NK cells adhere to and lyse porcine endothelial cells (pEC) and therefore may contribute to the cell-mediated rejection of vascularized pig-to-human xenografts. Since MHC class I molecules inhibit the cytotoxic activity of NK cells, the expression of HLA genes in pEC has been proposed as a potential solution to overcome NK cell-mediated xenogeneic cytotoxicity. HLA-G, a minimally polymorp...

AIM This paper is a short review on the state-of-the-art of the use of polyelectrolyte complexes containing polysaccharides for wound and burn healing and treatment using the chitosan/hyaluronic acid polyelectrolyte complex (PEC) hydrogel. RESULTS AND CONCLUSIONS PEC is suitable for wound healing because a wet treatment can be realized and both components of PEC contribute by their properties...
