Abstract
Semi-essential amino acid L-arginine may be of fundamental importance in various intracellular and intercellular pathways related to skin repair and wound healing. Our current study was aimed to explore the effect of L-arginine on skin fibroblast (L929) signaling pathways involved in cell proliferation (Akt-pAkt kinase, Erk/pErk1/2 kinase, JNK/pJNK kinase and pStat-1), apoptosis (Bcl2 and Bax) and immune defense (NF-κB and CD26). Significant upregulation of Erk (p<0.011), pErk (p<0.017) and JNK (p<0.002) was documented, while the rise was not significant for pJNK kinase. The Akt/pAkt signaling pathway did not change significantly for the above-mentioned time and dose, while pStat-1 was significantly down regulated (p<0.011). The exposure of skin fibroblasts to L-arginine increased anti-apoptotic Bcl2/Bax stoichiometry ratio (p<0.05), obtained by calculation of their individual quantities. L-arginine was able to elicit NF-κB signaling through the increase of p65 active subunit level (p<0.004), while CD26 surface antigen level was not significantly changed. In conclusion, the exposure of skin fibroblasts to L-arginine may help in maintaining and stimulating skin fibroblast proliferative, anti-apoptotic and immune defense function. Therefore, the proposed L-arginine dose may be used for tissue regeneration application, which would be of importance in regenerative medicine, skin rejuvenation approaches and wound healing.

Abstract
OBJECTIVES The aim of this study was to test the cytostatic potential of ketoprofen in the in vitro treatment of cells derived from colon and cervix cancer. BACKGROUND NF-κB and cyclooxygenase can have a role in different stages of the development and progression of cancer. In recent years, special attention has been paid to the possible cytostatic potential of nonsteroidal anti-inflammatory drugs. There are no published data on the use of ketoprofen in pharmacotherapy of the colon and cervical carcinoma. METHODS We examined the effect of ketoprofen alone or in combination with cisplatin and 5-fluorouracil on proliferation of the two cell lines, HeLa (human cervical carcinoma cells) and Caco-2 (human colon cancer cells) by MTT test. Measurement of the level of NF-κB was also performed in the cells of both cell lines. RESULTS The results of present study have shown that at least one of the mechanisms of antiproliferating and/or cytostatic effects of different concentrations of ketoprofen on Caco-2 and HeLa cells could include the transcription factor NF-κB. CONCLUSIONS Since this transcription factor is controlled by the altered expression of COX-2, the inhibition of this enzyme by ketoprofen may represent a significant step in synergistic cascade of the therapy and prevention of colon and cervical cancer (Tab. 4, Ref. 31).

Abstract
Hyperuricemia is a biochemical hallmark of gout, renal urate lithiasis, and inherited purine disorders, and may be a result of enormous ATP breakdown or purine release as a result of cardiovascular disease, hypertension, kidney disease, eclampsia, obesity, metabolic syndrome, psoriasis, tumor lysis syndrome, or intense physical training. The beneficial role of dairy products on hyperuricemia management and prevention is well documented in the literature. The primary aim of our experimental study was to examine the effect of milk dietary regimen (commercial 1.5% fat UHT milk or patented depurinized milk) compared with allopurinol therapy on experimental hyperuricemia induced by oxonic acid in rats. Principal component analysis was applied on a data set consisting of 11 variables for 8 different experimental groups. Among the 11 parameters measured (plasma uric acid and the liver parameters NFκB-p65, Akt kinase/phospho-Akt kinase, ERK kinase/phospho-ERK kinase, IRAK kinase/phospho IRAK kinase, p38/phospho-p38, and DNase), Akt/phospho Akt and ERK/phospho-ERK signaling were extracted as the most discriminating. We also compared the content of various potentially toxic compounds (sulfur compounds, ketones, aldehydes, alcohols, esters, carboxylic acids, and phthalates) in untreated commercial milk and depurinized milk. Of all the compounds investigated in this study that were observed in commercial milk (24 volatile organic compounds and 4 phthalates), 6 volatile organic compounds were not detected in depurinized milk. For almost all of the other compounds, significant decreases in concentration were observed in depurinized milk compared with commercial milk. In conclusion, a depurinized milk diet may be recommended in nutritional treatment of primary and secondary hyperuricemia to avoid uric acid and other volatile, potentially toxic compounds that may slow down liver regeneration and may induce chronic liver diseases.

Abstract
L-arginine is conditionally essetcial amino acid, required for normal cell growth, protein synthesis, ammonia detoxification, tissue growth and general performance, proposed in the treatment of men sterility and prevention of male impotence. The aim of the present paper was to estimate the activity of the enzymes of adenine nucleotide metabolism: 5'-nucleotidase (5'-NU), adenosine deaminase (ADA), AMP deaminase, and xanthine oxidase (XO), during dietary intake of L-arginine for a period of four weeks of male Wistar rats. Adenosine concentration in tissues is maintained by the relative activities of the adenosine-producing enzyme, 5'-NU and the adenosine-degrading enzyme-ADA adenosine deaminase. Dietary L-arginine intake directed adenine nucleotide metabolism in liver, kidney, and testis tissue toward the activation of adenosine production, by increased 5'-NU activity and decreased ADA activity. Stimulation of adenosine accumulation could be of importance in mediating arginine antiatherosclerotic, vasoactive, immunomodulatory, and antioxidant effects. Assuming that the XO activity reflects the rate of purine catabolism in the cell, while the activity of AMP deaminase is of importance in ATP regeneration, reduced activity of XO, together with the increased AMP-deaminase activity, may suggest that adenine nucleotides are presumably directed to the ATP regenerating process during dietary L-arginine intake.
