The structural similarity between substance P (SP, Arg-Pro-Lys-Pro-Gln-Gln-Phe-Phe-Gly-Leu-Met-NH(2)) and Arg/Pro rich bactericidal peptides suggests a possible direct effect of SP on invasive microbes. We now present evidence that substance P possesses direct antimicrobial activity, highest against S. aureus. A substance P antagonist also possesses such(More)
The RNA exosome is an essential ribonuclease complex involved in RNA processing and decay. It consists of a 9-subunit catalytically inert ring composed of six RNase PH-like proteins forming a central channel and three cap subunits with KH/S1 domains located at the top. The yeast exosome catalytic activity is supplied by the Dis3 (also known as Rrp44)(More)
Atherosclerosis commonly affects the arteries harvested from patients 70 years of age or older. Saphenous vein grafts appear to maintain a higher patency rate after coronary artery bypass grafting in these subjects. The infiltration of macrophages is an early step in saphenous vein graft atherosclerosis; however, little is known regarding the underlying(More)
The Fos family of transcription factors may play a key role in various forms of brain plasticity. Among different genes coding Fos proteins is the fosB gene. Protein products of the fosB gene are thought to be critically involved in neural adaptations produced by chronic treatment with drugs of abuse. fosB gene transcription leads to accumulation of(More)
PURPOSE OF REVIEW Berries belong to the best dietary sources of bioactive compounds, which exert a synergistic and cumulative effect on promotion of human health and prevention of diseases. The present review presents the most recent findings of animal and human studies regarding the health benefits of berries in terms of prevention and treatment of(More)
Paraoxonase (PON) is a group of proteins present in three forms (PON1, PON2, PON3) encoded by genes PON1, PON2, and PON3. PON1 and PON3 are plasma enzymes, structurally and functionally related to HDL, while PON2 is characterized by an intracellular location. Many polymorphisms of PON have been observed. The most widely and accurately described is the(More)
Cranberries (Oxycoccus quadripetalus) are a valuable source of bioactive substances with high antioxidant potential and well documented beneficial health properties. In the present study, the activity of cranberries, in terms of the inhibiting effects of adipogenesis, was investigated using the 3T3-L1 cell line. The obtained results showed that cranberries(More)
This review discusses the preventive and therapeutic potential of natural dietary compounds against colorectal cancer. The chemopreventive properties of many natural food matrices and purified bioactive compounds have been evaluated. Prominent among the dietary constituents that are the focus of interest in colorectal cancer chemoprevention are dietary(More)
It has previously been shown that lyophilized cranberries (LCB) decreased lipid accumulation in 3T3-L1 cells and inhibited preadipocyte differentiation by down-regulation of the expression of key transcription factors (PPARγ, C/EBPα, SREBP1) of the adipogenesis pathway. To elucidate the molecular basis of anti-lipogenic activity of LCB, the expression of(More)
The aim of the paper is to explore a causal nexus between contract type (financing rules and scale of responsibilities) and tendency towards integration between Polish health care providers. For more than 40 years Polish health care sector structures were fully integrated. The law introduced in 1991 initiated development of a system of contracts between(More)
