ZNF703 gene copy number and protein expression in breast cancer; associations with proliferation, prognosis and luminal subtypes.

Purpose: Amplification of 8p12 is frequent in breast cancer and associated with poor prognosis in luminal subtypes. ZNF703 has been identified as the driver gene of proliferation in the A1 amplicon situated in 8p12. In this study, the aims were to investigate associations between ZNF703 copy number alterations and molecular subtypes, proliferation and prognosis, and using immunohistochemistry, examine associations between ZNF703 copy number and ZNF703 protein expression.

Potential sources of conflict in intensive care units - a questionnaire study.

Background: Conflicts occur in intensive care units (ICUs), and an international multicentre study conducted in 2008, including 323 ICUs from 24 European countries, confirmed the occurrence of this phenomenon. There are no data in Poland. The aim of the study was to analyse the frequency of the occurrence of conflicts in ICUs in Polish hospitals, and their most frequent sources.

Uncultured and Account for Major Acetate Assimilation in a Coastal Marine Sediment.

Acetate is a key intermediate in anaerobic mineralization of organic matter in marine sediments. Its turnover is central to carbon cycling, however, the relative contribution of different microbial populations to acetate assimilation in marine sediments is unknown. To quantify acetate assimilation by abundant bacterial populations, we incubated coastal marine sediments with C-labeled acetate and flow-sorted cells that had been labeled and identified by fluorescence hybridization.

Activity and community structures of sulfate-reducing microorganisms in polar, temperate and tropical marine sediments.

Temperature has a fundamental impact on the metabolic rates of microorganisms and strongly influences microbial ecology and biogeochemical cycling in the environment. In this study, we examined the catabolic temperature response of natural communities of sulfate-reducing microorganisms (SRM) in polar, temperate and tropical marine sediments. In short-term sediment incubation experiments with (35)S-sulfate, we demonstrated how the cardinal temperatures for sulfate reduction correlate with mean annual sediment temperatures, indicating specific thermal adaptations of the dominant SRM in each of the investigated ecosystems.

[Acute novel drugs poisoning among patients of Nofer Institute of Occupational Medicine in Lodz, Toxicology Unit, hospitalized in the years 2008-2012--epidemiology, clinical state].

Unlabelled: Intoxication with novel recreational drugs poses significant challenge for medical staff due to diagnostic difficulties, complex clinical pattern, resulting from polyethiology of poisoning and potential risk of life threatening complications.

Objectives: Description of clinical pattern novel drug intoxication.

Methods: retrospective review of medical records patients hospitalized in the Toxicology Unit (TU) with diagnosis of intoxication with novel recreational drugs.

[Acute ethylene glycol poisoning among patients of Nofer Institute of Occupational Medicine in Łódź, Toxicology Unit, hospitalized in the years 2000-2009].

Acute poisonings with ethylene glycol pose real challenge in the clinical toxicology. The main objective of this study is an analysis of clinical features and identification of prognostic factors in poisoning with ethylene glycol of patients hospitalized in the Toxicology Unit in the years 2000-2009. The medical records of the patients were identified and separated.

Haddad syndrome.

Haddad syndrome is a rare genetically conditioned disease. We present a female newborn with congenital central hypoventilation syndrome associated with Hirschprung's disease. The infant is mechanically ventilated and parentally fed in a home setting.

Effects of freeze-thaw cycles on anaerobic microbial processes in an Arctic intertidal mud flat.

Insight into the effects of repeated freezing and thawing on microbial processes in sediments and soils is important for understanding sediment carbon cycling at high latitudes acutely affected by global warming. Microbial responses to repeated freeze-thaw conditions were studied in three complementary experiments using arctic sediment collected from an intertidal flat that is exposed to seasonal freeze-thaw conditions (Ymerbukta, Svalbard, Arctic Ocean). The sediment was subjected to oscillating freeze-thaw incubations, either gradual, from -5 to 4 degrees C, or abrupt, from -20 to 10 degrees C.

Radiation therapy toxicity to the skin.

Radiation therapy has been integral to cancer patient care. The skin is an intentional and unintentional target of therapy, and is sensitive to the volume of normal tissue in the radiation therapy treatment field, daily treatment dose (fractionation), and total treatment dose. We must understand the relationship of these factors to patient outcome as we move toward hypofractionation treatment strategies (radiosurgery).

[The incidence of the pituitary autoantibodies in Graves' disease].

Introduction: It is known that in the sera of patients with Graves, Addison and other autoimmune endocrine diseases we can detect autoantibodies against pituitary antigens. The aim of the study was evaluation of pituitary autoantibodies in Graves' disease patients using immunoblotting methods.

Material And Methods: Studies were performed in 32 Graves' disease patients, 25 women (age range: 31-67 yrs, median: 49.

Evaluating degenerative changes in the wrist after surgical treatment for scaphoid pseudarthrosis using a corticocancellous graft for anatomical reconstruction.

Background. Pseudoarthrosis of the scaphoid results in the development of carpal instability and severe posttraumatic osteoarthritis. Modern methods of treatment focus on reconstruction of the anatomical shape and length of the scaphoid.

The TP53 codon 72 polymorphism and predisposition to adrenocortical cancer in Polish patients.

The TP53 polymorphism occurs at codon 72 of exon 4 with two alleles encoding either arginine or proline. The association between this common polymorphism and risk of different cancers has been extensive studied, however various reports are controversial. We have analyzed the 72Pro polymorphic variant in patients with adrenocortical tumors to evaluate whether 72G--> C substitution at codon 72 of TP53 gene may be associated with increased risk for malignancy in adrenal cortex in comparison to the control group.

[Tobacco smoking in patients with hyperthyroidism].

The objective of this study was to determine the impact of cigarette smoking in hyperthyroidism patients. The study group included patients with Graves-Basedow disease (GB): n = 317 (32.9%), patients with Graves' ophthalmopathy (GO): n = 108 (11.
