Abstract
Breast carcinomas represent an important health problem. Understanding the development of breast cancer from precursor is critical for clinical treatment and prevention, however little is known about the molecular events involved in the progression to cancer. The advent of gene expression microarray technology provides a new powerful tool to assist in the determination of diagnosis, prognosis and treatment. In this paper, we present the recent DNA microarray studies that describe how gene expression profiling is being used to classify specimens of breast carcinomas based on molecular properties of the tumor and to identify gene expression patterns related to clinical outcome. In present, data are available that show that gene expression profiles can be used to distinguish cell type-specific gene clusters (stromal, epithelial, mesenchymal and proliferation status) and to classify breast tumors as basal-like, luminal-like, ERBB2 overexpressing and normal breast-like. Profiles associated with good prognosis and poor prognosis of young axillary node negative patients have been identified. The microarray technology will become in the near future a molecular complement to histopathology and immnuhistochemistry.

Abstract
HIV infection is continuously raising, and different treatments did not manage to extend the patient's life. Clinical and morphopathological features of respiratory, gastrointestinal, hematological and nervous system are well characterized in HIV infection, but cardiac involvement is not so well known. Cardiac involvement is extremely rare in HIV disease, but demonstrated by echocardiography and anatomo-pathologic methods, it is more frequently met than the clinical features are supposed to be, and it can be demonstrated by positive serologic tests.The main reason of this research is the necessity to obtain data from HIV infection concerning heart involvement.

Abstract
The aim of this study was to obtain four collagen based porous scaffolds and to assess their in vitro biocompatibility and biodegradability in order to use them for skin tissue engineering. We have prepared four variants of collagen-based biodegradable sponges by liophilization of type I collagen solution and three variants of collagen-agarose mixture in different ratios 2:1 (A), 1:1 (B) and 1:2 (C). These scaffolds had microporous structure with a higher than 98% porosity and a reduced biodegradation after their exposure to UV radiation. The incorporation of agarose into the collagen scaffolds has improved their structural stability. In vitro biocompatibility testing for the four types of sponges was performed on a stabilized fibroblast cell line and showed that both cell viability and morphology were not altered by collagen and collagen-agarose variants A and B sponges. These three porous sponges demonstrated potential for future application as cell scaffolds in skin tissue engineering.

Abstract
The aim of this study was to assess the antibacterial and antifungal potential of some Romanian medicinal plants, arnica--Arnica montana, wormwood--Artemisia absinthium and nettle--Urtica dioica. In order to perform this antimicrobial screening, we obtained the vegetal extracts and we tested them on a series of Gram-positive and Gram-negative bacteria, and also against two fungal strains. The vegetal extracts showed antimicrobial activity preferentially directed against the planktonic fungal and bacterial growth, while the effect against biofilm formation and development was demonstrated only against S. aureus and C. albicans. Our in vitro assays indicate that the studied plant extracts are a significant source of natural alternatives to antimicrobial therapy, thus avoiding antibiotic therapy, the use of which has become excessive in recent years.

Abstract
We report very low temperature ( T) thermopower and resistivity ( rho) measurements on variable-density, two-dimensional hole systems confined to GaAs quantum wells. As the hole density is lowered from 1.49x10(11) cm(-2) to 0.14x10(11) cm(-2), the system crosses from an insulating ( drho / dT less, similar0) to a metallic regime ( drho / dT>0) and finally displays insulating behavior ( drho / dT<0). Diffusion thermopower shows a striking sign reversal in a narrow range of density in the metallic regime, suggesting a qualitative change in the conduction or the scattering mechanism.

Abstract
The small GTP-binding protein family including Rac proteins represents a paradigm for signaling molecules shared by animal and plants. In mammalian cells, Rac induces the activation of NADPH oxidase leading to superoxide production. In plants, evidence suggests that resistance to pathogens depends on superoxide that is generated via NADPH oxidase-like enzymes. We have identified four closely related Rho/Rac genes from Zea mays that exhibit a high degree of homology to the human Rac. We hypothesized that these plant Rac proteins could function as their mammalian counterpart and activate an enzymatic complex that leads to superoxide production. Here, we show that like human Rac1, activated Zea mays Rac genes can induce superoxide production, when expressed in a mammalian system: NIH 3T3 cells. Our results suggest that in plants, Rac proteins can function as activators of oxidative burst and indicate the remarkable functional and structural conservation of Rho/Rac proteins between plant and animal kingdoms during evolution.

Abstract
We studied the association between the production of reactive oxygen species, actin organization, and cellular motility. We have used an endothelial cell monolayer-wounding assay to demonstrate that the cells at the margin of the wound thus created produced significantly more free radicals than did cells in distant rows. The rate of incorporation of actin monomers into filaments was fastest at the wound margin, where heightened production of free radicals was detected. We have tested the effect of decreasing reactive oxygen species production on the migration of endothelial cells and on actin polymerization. The NADPH inhibitor diphenylene iodonium and the superoxide dismutase mimetic manganese (III) tetrakis(1-methyl-4-pyridyl)porphyrin (MnTMPyP) virtually abolished cytochalasin D-inhibitable actin monomer incorporation at the fast-growing barbed ends of filaments. Moreover, endothelial cell migration within the wound was significantly retarded in the presence of both diphenylene iodonium and MnTMPyP. We conclude that migration of endothelial cells in response to loss of confluence includes the intracellular production of reactive oxygen species, which contribute to the actin cytoskeleton reorganization required for the migratory behavior of endothelial cells.

Abstract
A variety of stressful events can trigger the production of free radicals by exposed cells. For years, the effect of such highly reactive radicals was expected to be damaging to cells, altering their biology irreversibly. However, many recent reports have shown that reactive oxygen species can have additional functions, and contribute to important signaling pathways to regulate key biological responses, including cell migration, mitosis, and apoptosis. With this review, we address the role of the small GTP binding protein, Rac, as a regulatory protein that controls superoxide production, and the effect of superoxide and derived oxidants in cell signaling.

Abstract
The small GTPase rac1 controls actin redistribution to membrane ruffles in fibroblasts and other cell types, as well as the activation of the NADPH oxidase in phagocytes. We explored the possibility that these two processes could be related. We used a replication-deficient adenoviral vector to overexpress the constitutively active form of rac1, racV12, in human and mouse aortic endothelial cells. We show here that, in addition to membrane ruffle formation, racV12 induced an increase in the total amount of F-actin within endothelial cells. Concurrently, racV12-overexpressing cells produced significantly higher amounts of free radicals, as detected by the fluorescent probe 5-(and-6)-chloromethyl-2',7'-dichloro-dihydrofluorescein diacetate, than cells infected with a control virus encoding the bacterial beta-galactosidase (Ad-betaGal). To assess the specific role of superoxide in racV12-induced actin reorganization, we co-expressed the human enzyme Cu,Zn-superoxide dismutase (SOD), by means of another adenoviral vector construct. Overexpressed SOD reduced the concentration of superoxide detected in Ad-racV12-transfected cells and reversed the effects of Ad-racV12 on the content of filamentous actin. MnTMPyP, an SOD mimetic, as well as the antioxidant N-acetyl cysteine, had similar effects, in that they reduced not only the free radicals production, but also ruffle formation and the concentration of F-actin within racV12-overexpressing endothelial cells. Our data support the hypothesis that superoxide is one of the important mediators acting downstream of rac1 on the pathway of actin cytoskeleton remodeling in endothelial cells.

Abstract
The authors compared blood loss, transfusion requirements, and heparin doses for reoperative cardiac surgery using either: a) a Duraflow (Baxter Corporation, Irvine, CA) heparin coated cardiopulmonary bypass (CPB) system or b) standard CPB. Twenty patients underwent redo cardiac surgery while supported with heparin coated CPB, and 17 patients underwent redo cardiac surgery with standard CPB. The following data are presented as mean +/- standard deviation. The heparin coated CPB circuit group received significantly less heparin than the standard CPB group (322 +/- 80 IU/kg versus 448 +/- 80 IU/kg, p < 0.01). There was no difference in blood loss in the first 24 postoperative hrs or mean transfusion requirements for the two groups. Despite the reduced dose of heparin, the mean activated clotting time in the heparin coated group was similar to the mean activated clotting time of the standard CPB group (577 +/- 98 sec versus 612 +/- 117 sec, p = ns). In conclusion, heparin coated CPB without reduced activated clotting time does not reduce transfusion requirements or blood loss in reoperative cardiac surgery. The heparin coated CPB system allows maintenance of the activated clotting time level despite reduced heparin doses.

Abstract
Qualitative ultrastructural autoradiography was used to study the binding of the vascular anticoagulant alpha (annexin V) to normal and atherosclerotic (AS) rabbit aortic intima. Recombinant annexin V was labelled with 125I by the Iodogen method. Rabbits were fed a hypercholesterolemic (HC) diet up to 10 months. After laparotomy and exsanguination, the aortae were perfused with dilutions of 125I-annexin V (I-AV) for 10-15 min, either on ice or at 22 degrees C and then perfusion-fixed with aldehydes. Fragments of the labelled aortae were used for en face contact autoradiography, followed by Sudan Black staining of intimal lipid. Specimens were also included in Epon and sectioned for light- and electron-microscopic autoradiography. The binding of I-AV was increased on the AS aortae as compared with the normal ones, with an apparent preference for the lesioned areas. Microscopically, I-AV was found at the luminal front of aortic intima, on endothelial cells (EC), on macrophage foam cells, and on their disrupted remnants. The presence of the AV binding sites (reportedly known to interact with high affinity with phosphatidylserine) in the rabbit AS aortic intima, together with other known procoagulant conditions, may contribute to the initiation of coagulation events into the lesioned vascular wall, and may offer a rationale for the use of annexin V as an anticoagulant drug.

Abstract
Cultured bovine aortic endothelial cells (BAEC) were incubated for 5 days with 10(-5) 4-hydroxynonenal (HN). HN treated BAEC and controls were either (i) further incubated with 125I-polymyxin B (IPxB) or with radioiodinated, inactivated coagulation factor Xa (IFXai) as markers of membrane phospholipid perturbation, or (ii) assayed for the synthesis of prostacyclin (PGI2) and thromboxane A2 (TXA2). Rabbit blood mononuclear cells enriched in monocytes (MC) were isolated and assayed for chemotactic response to HN. The results showed six - fold increases of IPxB and IFXai binding to BAEC treated with HN, as compared to untreated controls. We also found in HN treated cells a marked inhibition of PGI2 synthesis, but an unmodified TXA2 production. In addition, HN in the 10(-5)-10(-10) M range induced oriented migration of MC.

Abstract
The authors study the etiology of chronic hepatitis, with emphasis on the high frequency of the infection with virus B, with a chronization rate of 15-20%. Taking into account the mother fetus, transmission and the increased number of AgHBs chronic carriers, with serious consequences on hepatic affection, the authors insist on the necessity of antiviral vaccination and of the therapy for virus elimination. At the same time, pathogenetic investigations are made for the presence of nonspecific antibodies and antibodies against hepatocytic membrane, elements which prove the permanent character of the hepatic lesions by immune mechanism, induced by the virus B persistence.

Abstract
The clinical, functional-histological and mainly the therapeutical aspect in chronic hepatitis, still raises important problems in children's pathology. As the clinical aspect of the chronic liver diseases is variable and less suggestive in the early and even advanced stages in children, the authors followed--for three years--the incidence of biochemical and histological functional disturbances in a closed collectivity of children. Since no specific therapeutical possibilities exist yet, the importance for a better knowledge of epidemiology of post-viral chronic hepatitis is emphasized.
