Objective: The aim of this study is to determine biomarkers, which may be used in order to understand the pathophysiology, the diagnosis, progression surveillance/monitoring, and treatment efficacy of high graded glial tumors.
Background: Radiological imaging in the diagnosis and relapse surveillance of glial tumors is sometimes insufficient. There is need for additional methods of diagnosis and surveillance in order to rule out contradictory circumstances.
Method: Using enzyme like immune sorbent assay method, E-Cadherin, Tenascin C, Tetraspanin 8, Survivin and VEGF121 levels were investigated in serum and tumor tissues of 28 patients diagnosed with pathological glioblastoma, and in the serum of 26 healthy individuals. Correlation between tumor tissue values and Ki67 percentage, and P53 mutation, and difference between unhealthy and healthy serum levels were sought.
Results: It was found out that E-Cadherin and VEGF 121 levels in the unhealthy serum were high in comparison to the control group (p 0.05).
Conclusion: EC and VEGF121 are biomarkers, which have the potential to be used in the diagnosis, recurrence and treatment follow-up in high graded glial tumors (Tab. 2, Fig. 1, Ref. 37). Text in PDF www.elis.sk Keywords: E-Cadherin, VEGF, Survivin, Tenascin-C, Tetraspanin, glioblastoma.

Unlabelled: In the aquaculture sector, one of the challenges includes disease outbreaks such as bacterial infections, particularly from (), impacting both wild and farmed fish. In this study, we conducted a proteomic analysis of the intestinal tissue in following infection to elucidate the protein alterations and its implications for immune response. Our findings indicate significant dysregulation in extracellular matrix (ECM)-associated proteins during infection, with increased abundance of elastin and collagen alpha-3(VI).

Objective: Identify gene changes in articular cartilage of the medial tibial plateau (MTP) at 2, 4 and 8 weeks after destabilisation of the medial meniscus (DMM) in mice. Compare our data with previously published datasets to ascertain dysregulated pathways and genes in osteoarthritis (OA).
Design: RNA was extracted from the ipsilateral and contralateral MTP cartilage, amplified, labelled and hybridized on Illumina WGv2 microarrays.
The isolation and characterization of a population of extravillous trophoblast progenitors from first trimester human placenta.

Department of Obstetrics and Gynecology, University of Auckland, Auckland 1001, New Zealand.
Background: It is widely accepted that most if not all villous cytotrophoblasts from term placentae are committed to differentiate into syncytiotrophoblast, but that early in gestation villous cytotrophoblasts are bipotential and capable of differentiating into either extravillous trophoblasts (EVTs) or syncytiotrophoblast. In contrast, our previous work has suggested that two separate populations of cytotrophoblast exist in the first trimester, one committed to EVT differentiation and the other to syncytiotrophoblast differentiation. In this work, we have isolated and characterized the population of 'EVT progenitors'.

Aim: To seek good markers to predict invasion and metastasis of gastrointestinal adenocarcinoma (GIA).
Methods: Expression of KAI1 and tenascin were examined on tissue microarrays containing gastric adenocarcinoma (n = 98), colorectal adenocarcinoma (n = 125), gastric adjacent non-cancerous mucosa (n = 95) and colorectal adjacent non-cancerous mucosa (n = 112) by immunostaining. Microvessel density (MVD) in GIA was labelled using anti-CD34 antibody by immunostaining.
