An Immunohistochemical Study of MAGE Proteins in Hepatocellular Carcinoma.

Hepatocellular carcinoma (HCC) is one the most common primary malignancies with high mortality and morbidity. The melanoma-associated antigen (MAGE) gene family includes several genes that are highly expressed in numerous human cancers, making many of them part of the cancer-testis antigen (CTA) family. MAGE-C1 is expressed in various malignancies but is absent in normal cells, except for the male germ line.

The association between leptin, adiponectin levels and the ovarian reserve in women of reproductive age.

Background: Reproduction ability requires a certain amount of body fat that is necessary for ovulation, menstruation and pregnancy. Fat tissue represents an endocrine organ with high metabolic activity as it produces adipokines such as leptin and adiponectin. Our aim is to examine potential associations between women of reproductive age's ovarian reserves and their levels of leptin and adiponectin.

Viral-induced inflammation can lead to adverse pregnancy outcomes.

Parvoviruses are DNA viruses of small size. There have been a number of reports indicating the possible effects of B19 infections during pregnancy. These effects include spontaneous abortions, stillbirth, fetal damage, and quite often, fetal anemia with hydrops fetalis.

In this study, we examined their potential in pigs, using biodegradable collagen conduits filled with DPSCs. To our knowledge, this is the first time DPCSs are tested for peripheral nerve regeneration in such large animal model.

Effects of gestational maternal undernutrition on growth, carcass composition and meat quality of rabbit offspring.

An experiment was conducted in order to evaluate the effects of gestational undernutrition of rabbit does on growth, carcass composition and meat quality of the offsprings. Thirty primiparous non lactating rabbit does were artificially inseminated and randomly divided in three treatment groups: Control (C; fed to 100% of maintenance requirements throughout gestation, n = 10), early undernourished (EU; fed to 50% of maintenance requirements during days 7-19 of gestation, n = 10) and late undernourished (LU; fed to 50% of maintenance requirements during days 20-27 of gestation, n = 10). During the 4th week of the gestation period, LU does significantly lost weight compared to C and EU groups (P<0.

A study on the age dependency of gustatory states: low-frequency spectral component in the resting-state MEG.

Magnetoencephalography (MEG) recordings were evaluated for 25 healthy female volunteers, in five different gustatory states: normal, sweet, bitter, sour and salty. The study population was divided in two groups according to age: group A (10-19 years old) and group B (20-30 years old). There was a higher count of low frequencies (2 Hz) and a lower count of high frequencies (7 Hz) with increasing age, in all studied states.

Combination of very low energy diets and pharmacotherapy in the treatment of obesity: meta-analysis of published data.

Obesity has reached epidemic proportions globally, with more than 1 billion adults overweight - at least 300 million of them clinically obese - and is a major contributor to the global burden of chronic disease (heart disease and diabetes) and disability. The aim of the study was to perform a systematic review and meta-analysis of published data on the combination of very low energy diets also known as very low calorie diets and pharmacotherapy for its effectiveness in the treatment of obesity. A MEDLINE (Pubmed) search from 1970 to 2009 using multiple combinations of the relevant terms was carried out; the matching articles were also searched for additional references.

The cytogenetic action of ifosfamide, mesna, and their combination on peripheral rabbit lymphocytes: an in vivo/in vitro cytogenetic study.

Ifosfamide (IFO) is an alkylating nitrogen mustard, administrated as an antineoplasmic agent. It is characterized by its intense urotoxic action, leading to hemorrhagic cystitis. This side effect of IFO raises the requirement for the co-administration with sodium 2-sulfanylethanesulfonate (Mesna) aiming to avoid or minimize this effect.

Distribution of ABO and Rh blood groups in Greece: an update.

The aim of this study was to investigate and evaluate the frequency of the antigens classifying the ABO and Rh blood groups in the Greek population. In this study the 3.5% were first generation immigrants with both their parents immigrants from countries of the USSR, while 1.

Co-expression of survivin, c-erbB2, and cyclooxygenase-2 (COX-2): prognostic value and survival of endometrial cancer patients.

Aim: The purpose of this study was to investigate the co-expression of survivin, c-erbB2, and COX-2 in endometrial cancer tissues and evaluate its prognostic significance in endometrial cancer

Methods: Tumor tissue biopsies from 110 patients with primary untreated endometrial carcinomas were studied by immunohistochemistry. Statistical analysis evaluated correlation of antigen expression with tumor stage, grade, myometrial invasion, and histologic type. Association with disease outcome was also investigated

Results: The results showed that expression of the three antigens was independently associated with histological grade, disease stage, and myometrial invasion.

Erythropoietin and growth factors exhibit differential angiogenic potential in mouse heart.

Background: The possible angiogenic effect of recombinant human erythropoietin (rHuEpo) and several possibly angiogenic cytokines such as basic fibroblast growth factor (bFGF), acidic fibroblast growth factor (aFGIF) and vascular endothelial growth factor (VEGF) was investigated in mouse heart.

Materials And Methods: Mice were divided into five groups (n = 7/group): A, control; B, rHuEpo-treated; C, (aFGF-treated); D, (VEGF-treated); E, (bFGF-treated). The antibody mouse anti-human CD31 was used to evaluate the vessels present in histological preparations.

Ghrelin in pathological conditions.

The recently identified gastric hormone ghrelin was initially described as a natural Growth Hormone Secretagogue Receptor ligand. Apart from ghrelin's first discovered action, which was the stimulation of Growth Hormone release, implications for many other functions have been reported. It seems that ghrelin exhibits an important role in conditions related to processes regulating nutrition, body composition and growth, as well as heart, liver, thyroid or kidney dysfunction.

Erythropoietin enhances angiogenesis in an experimental cyclosporine A-induced nephrotoxicity model in the rat.

1. Erythropoietin (EPO) is a hormone regulating the proliferation and differentiation of erythroid precursor cells. The hypothesis that haematopoietic and endothelial cells share a common haemanglioblast progenitor among others is based on the finding that both cell lineages express cell surface antigens, such as CD31 and CD34.

Cytokine profile in cases with premature elevation of progesterone serum concentrations during ovarian stimulation.

The aim of this study was to investigate the concentrations of vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), leptin, tumor necrosis factor-alpha, interleukin (IL)-1beta and IL-6, in cycles with a premature rise of serum progesterone. 25 intracytoplasmic sperm injection (ICSI) cycles with (Group 1) and 25 ICSI cycles without a premature progesterone elevation (Group 2) were included. The cut-off value of serum progesterone on the day of human chorionic gonadotropin (hCG) administration was 0.
