Body composition and nutrition of female athletes

2019

Background. The somatic features of the athletes’ bodies partially determine their sporting level and are conditioned to a large extent by the state of nutrition. Objective. The aim of this paper is to present nutritional status and its correlation with the somatic determinants of training athletes and physical education students. Material and methods. This study involved 12 weightlifting players (subgroup-WL), 15 soccer players (subgroup-SP), 12 table tennis players (subgroup-TT) and 12 female students of physical education (subgroup-C). In all subjects, the age and somatic variables were recorded and the daily intake of energy, water, proteins, fats and carbohydrates was determined by 24-…

Multicenter Phase II Study of Lurbinectedin in BRCA-Mutated and Unselected Metastatic Advanced Breast Cancer and Biomarker Assessment Substudy

2018

Purpose This multicenter phase II trial evaluated lurbinectedin (PM01183), a selective inhibitor of active transcription of protein-coding genes, in patients with metastatic breast cancer. A unicenter translational substudy assessed potential mechanisms of lurbinectedin resistance. Patients and Methods Two arms were evaluated according to germline BRCA1/2 status: BRCA1/2 mutated (arm A; n = 54) and unselected ( BRCA1/2 wild-type or unknown status; arm B; n = 35). Lurbinectedin starting dose was a 7-mg flat dose and later, 3.5 mg/m2 in arm A. The primary end point was objective response rate (ORR) per Response Evaluation Criteria in Solid Tumors (RECIST). The translational substudy of resist…

Comparative immunoexpression of ICAM-1, TGF-?1 and ki-67 in periapical and residual cysts

2016

Background This study compared the immunohistochemical expression of ki-67, transforming growth factor beta 1 (TGF-β1) and intercellular adhesion molecule-1 (ICAM-1) in inflammatory periapical cysts and residual cysts. Material and Methods The study sample was composed by 25 periapical cysts and 25 residual cysts and immunohistochemical reactions were carried out using antibodies directed against ICAM-1, TGF-β1 and ki-67. Clinical, radiological, gross, histological and immunohistochemical data were tabulated for descriptive and comparative analysis using the SPSS software and differences were considered statistically significant when p<0.05%. Results There were no differences between the ex…

Are general practitioners characteristics associated with the quality of type 2 diabetes care in general practice? Results from the Norwegian ROSA4 s…

2018

Abstract Objective: To explore the associations between general practitioners (GPs) characteristics such as gender, specialist status, country of birth and country of graduation and the quality of care for patients with type 2 diabetes (T2DM). Design: Cross-sectional survey. Setting and subjects: The 277 GPs provided care for 10082 patients with T2DM in Norway in 2014. The GPs characteristics were self-reported: 55% were male, 68% were specialists in General Practice, 82% born in Norway and 87% had graduated in Western Europe. Of patients, 81% were born in Norway and 8% in South Asia. Data regarding diabetes care were obtained from electronic medical records and manually verified. Main outc…

Glycated serum proteins and glucose tolerance

1988

Glycated serum proteins (GSP), stable glycated hemoglobin (HbA1c) together with some metabolic parameters were evaluated in 120 subjects, 30 with normal glucose tolerance (NGT), 30 with impaired glucose tolerance (IGT), 30 with non-insulin-dependent diabetes mellitus (NIDD), and 30 with insulin-dependent diabetes mellitus (IDD). GSP levels were significantly higher in IGT, NIDD and IDD than in NGT. HbA1c levels were not significantly higher in IGT in comparison with NGT, but were significantly higher in NIDD and in IDD than in NGT and IGT. GSP correlated better than HbA1c with all metabolic parameters considered. Taking into account the distribution of the values, GSP showed a smaller overl…

Differences in platelet growth factor release and leucocyte kinetics during autologous platelet gel formation.

2006

Three commercial systems for whole blood separation were compared to obtain the buffy coat composed of platelet-rich plasma (BC-PRP) and leucocytes . These samples of the buffy coat were used to make a platelet gel (PG), which was used to measure platelet growth factor (PGF) release, to perform a white blood cell (WBC) count and to measure myeloperoxidase (MPO) release from WBCs. Aliquots of whole blood obtained from ten volunteers were distributed either to a blood cell separator (The Electa Cell-Separator (TM), E-CS) or to a tabletop centrifuge (Gravitational Platelet Sequestration System (TM), GPS) to prepare the BC-PRP. The third system combines the BC-PRP production by E-CS with a micr…

PLA1/A2 polymorphism of the platelet glycoprotein receptors IIIA in Behçet's disease

2010

OBJECTIVES: To investigate potential associations between the PlA1/A2 polymorphism of the platelet glycoprotein receptor IIIA (GpIIIa) gene and venous thrombosis and other clinical manifestations in Italian patients with Behçet's disease (BD). METHODS: Two hundred consecutive Italian patients satisfying the International Study Group criteria for BD who were followed up for seven years and 241 healthy Italian age- and gender-matched blood donors were molecularly genotyped for the PlA1/A2 polymorphism of the platelet GpIIIa gene; 118 and 117 of the 200 BD patients were also respectively genotyped for factor V Leiden and prothrombin gene G20210A polymorphisms. A standard microlymphocytotoxicit…

Growth factor levels in platelet-rich plasma and correlations with donor age, sex, and platelet count.

2002

Abstract Introduction: Platelet-rich plasma contains autologous thrombocyte growth factors and might be promising for acceleration of dentoalveolar bone regeneration. In this study, it was analysed for platelet counts and growth factor concentrations. Material and method: Platelet-rich plasma was isolated by discontinuous cell separation from 158 healthy men and 55 women aged 17–62 years. One hundred and fifteen specimens (stratified for age and gender of the donor) were analysed for growth factor concentrations and platelet count. Results: The platelet count in platelet-rich plasma (1,407,640±320,100/μl) was 5 times higher than in donor blood (266,040±60,530/μl). Platelet-derived growth fa…

Quantification of thrombocyte growth factors in platelet concentrates produced by discontinuous cell separation.

2002

Platelet concentrates (PC) are increasingly used to increase bone regeneration in pre-prosthetic surgery. Although it is generally appreciated that certain growth factors (PDGF, TGF, EGF, and ECGF) are present in thrombocyte preparations, relatively little is known about these components in quantitative terms. The study reported here analysed the amounts of growth factors in PC produced under standard conditions from healthy volunteers. All the blood samples (237 in total) were analysed using Quantikine ELISA kits (R and D). The mean +/- SD platelet count in whole blood from these donors was 262,000+/-58,000/microl, while in PC produced by discontinuous cell separation it was 1.419,000+/-33…
