#1
Gonzalez-Bulnes, Chavatte-Palmer
BACKGROUND: The awareness of factors causing obesity and associated disorders has grown up in the last years from genome to a more complicated concept (developmental programming) in which prenatal and early-postnatal conditions markedly modify the phenotype and homeostasis of the individuals and determine juvenile growth, life-time fitness/obesity and disease risks. Experimentation in human beings is impeded by ethical issues plus inherent high variability and confounding factors (genetics, lifestyle and socioeconomic heterogeneity) and preclinical studies in adequate translational animal models are therefore decisive...

BACKGROUND: Women of reproductive age diagnosed with cancer are often interested in preserving gametes or reproductive tissue that would allow for future genetic parenthood. Preservation of fertility is often accomplished in young cancer patients via ovarian stimulation followed by oocyte or embryo cryopreservation. Conventional stimulation protocols, however, require 2-4 weeks to complete ovarian stimulation, oocyte retrieval and possible fertilization. Such a strategy may not be feasible in patients requiring urgent cancer treatment...

BACKGROUND: Coronary artery disease (CAD) is the most common reason for death in the western hemisphere. Therefore, a well-functioning risk-management has been established over the past decades with uprising interest in 'novel' biomarkers to predict adverse coronary events and detect patients with subclinical CAD. This review will focus on selected biomarkers belonging to the family of inflammatory markers (fibrinogen or hs-CRP) or to the family of lipid-associated markers (Lipoprotein associated PA2 or Lipoprotein a) and others are direct organ-specific biomarkers (hs-troponin, Cystatin C or NT-proBNP)...

Acute heart failure (AHF) has been one of the fields, where owing to difficulties in diagnosis, prognostic stratification and management the associated morbidity and mortality remains unusually high. The advent of novel biomarkers apart from the traditional B-type natriuretic peptide and N-terminal proBNP involved in myocardial injury, neuro-hormonal activation, and ventricular remodeling augurs immense hope in redefining our approach towards AHF. METHODS: Biomarkers like midregional proatrial natriuretic peptide, soluble ST2, highly-sensitive troponin, and midregional proadrenomedullin are some such examples that have passed various stages of substantiation while there is an array of potential biomarkers in nascent stages like osteopontin, CTGF, GDF-15 and TGF beta-1 awaiting further reiteration...

BACKGROUND: Biomarkers are indispensable tools for screening, diagnosis, and prognosis in cardiovascular diseases and their clinical application increases steadily. As cardiovascular diseases include various pathophysiological processes, no single biomarker, even natriuretic peptides, can be regarded as ideal fulfilling all necessary criteria for a comprehensive diagnostic or prognostic assessment revealing optimal clinical application. Hence, the multi-marker approaches using different biomarkers reflecting different pathophysiologies were highlighted recently...

BACKGROUND: Despite the extended laboratory and clinical study of sepsis, its diagnosis remains a clinical challenge. The initiation of sepsis activates many different biochemical and immunological pathways, which is expressed with alterations of many molecules on human tissues. The detection and the measurement of the concentration of such molecules, known as biomarkers, may be a diagnostic tool of great significance when the clinicians approach patients with suspected sepsis. Additionally, the may predicted the outcome and therefore they may have a role on the monitoring of the response to therapy...

Background The use of different types of plastics in the world either synthetic or biodegradable has become a part in all sectors of the economy. Infrastructure such as agriculture, building and construction, telecommunication, consumer goods, packaging, health and medical are all high growth areas that ensure a spiralling demand for plastics. Lack of degradability, environmental pollution and closing of landfill sites has led to concern more about plastic waste disposal. Appropriate biodegradation should occur for these water-immiscible polymers since they eventually enter streams which can neither be recycled nor incinerated and also not despoiled with existing physical and chemical means of degradation...

BACKGROUND: Angiogenesis is critical for the growth of tumor by supplying nutrients and oxygen that exacerbates the metastasis and progression of cancer. Noninvasive imaging of angiogenesis during the tumor therapeutic processes may provide novel opportunities for image-guided tumor management. OBJECTIVE: Here, we want to develop a mouse animal model for assessing cancer progression and angiogenesis in the same individuals by molecular imaging. METHODS: Breast cancer model was developed with mouse breast cancer cell line 4T1 carrying a reporter system encoding a triple fusion (TF) reporter gene consisting of renilla luciferase (Rluc), red fluorescent protein (RFP) and herpes simplex virus truncated thymidine kinase (HSV-ttk) in transgenic mice, which expressed firefly luciferase (Fluc) under the promoter of vascular endothelial growth factor receptor 2 (Vegfr2-luc)...
