Humic substances (HS) and natural organic matter (NOM) are natural organic compounds ubiquitous in the environment. However, some studies indicate that both HS and NOM can act as xenobiotics, e.g. induce hormone-like effects in fish, amphibians and invertebrates. Molecules of these substances contain a number of aromatic rings and conjugated double bonds--the so called chromophores. Irradiation...

CONTEXT The management of high-grade (Grade IV-V) renal injuries remains controversial. There has been an increase in the use of (NOM) but limited data exists comparing outcomes with open surgical exploration. OBJECTIVE To conduct a systematic review to determine if NOM is the best first-line option for high-grade renal trauma in terms of safety and effectiveness. EVIDENCE ACQUISITION Medli...

INTRODUCTION Management of Liver Trauma may vary widely from NOM +/- angioembolization to Damage Control Surgery. Multidisciplinary management is essential for achieving better outcomes. MATERIAL AND METHODS During 2000-2009 period 308 patients with liver injury were admitted to level 1 trauma center and recorded in Trauma Registry. Collected data are demographics, AAST grade, initial treatme...

Background: Recent research has provided evidences indicating the importance of endothelin axis in carcinogenesis. According to our knowledge, there are little information about endothelin A receptor (ETA) expression in oral squamous cell carcinoma (OSCC). So, the aim of the present study was to evaluate the immunohistochemical expression of ETA in OSCC and normal oral mucosa (...

efore the 1970s, research into the nature of natural organic matter (NOM) in drinking water and into methods for its removal was driven primarily by the desire to remove color from public water supplies. Since then, several other problems associated with NOM have been identified, including its demand for coagulants and disinfectants, its potential to transport metals and hydrophobic organic che...

Among the key environmental factors influencing the fate and transport of radionuclides in the environment is natural organic matter (NOM). While this has been known for decades, there still remains great uncertainty in predicting NOM-radionuclide interactions because of lack of understanding of radionuclide interactions with the specific organic moieties within NOM. Furthermore, radionuclide-N...

Aims. To investigate whether changes of meat consumption can affect body composition and laboratory parameters in healthy, normal weight, young women without the aim to reduce body weight. Research Design and Methods. Women volunteered to eat low-fat meat in addition to their habitual diet (M) or to exclude meat products from their diet (NOM). After 4 weeks M and NOM were crossed over between s...

BACKGROUND To determine whether angioembolization (AE) in hemodynamically stable adult patients with blunt splenic trauma (BST) at high risk for failure of nonoperative management (NOM) (contrast blush [CB] on computed tomography, high-grade IV-V injuries, or decreasing hemoglobin) results in lower failure rates than reported. METHODS The records of patients with BST from July 2000 to Decembe...

A forced-gradient tracer test was conducted at the Georgetown site to study the transport of natural organic matter (NOM) in groundwater. In particular, the goal of this experiment was to investigate the interactions between NOM and the aquifer matrix. A detailed three-dimensional characterization of the hydrologic conductivity heterogeneity of the site was obtained using slug tests. The transp...

Dans cet expose j'aimerais prouver qu'il y a des rapports tr~s ~troits entre la s~mantique nominale et la s~mantique verbale. J'essaierai d'appliquer la distinction entre nom comptable (angl. count noun) et nom de mati~re (angl. mass noun) au domaine du verbe. En particulier il sera d~montr~ qu'un verbe (ou syntagme verbal) ~ l'imparfait d~note une entit~ du mSme type que celle d~not~e par un n...
