Unlabelled: Inflammatory bowel disease (IBD) is associated with increased prevalence of bone demineralization. One of the risk factors for low bone density is the inadequate level of 25-OH vitamin D.

Aim: To determine the degree of bone demineralization in patients with IBD and the main causes leading to this condition.

Quantitative and qualitative bone assessment of the posterior mandible in patients with diabetes mellitus: a cone beam computed tomography study.

Unlabelled: Evaluation of mandibular bone features is very important for the diagnosis, treatment planning and management of dental procedures such as osseointegrated implants.

Aim: To evaluate the bone quantity and quality of the posterior region of the mandible using the CBCT technique for implant planning in patients with diabetes mellitus.

Methods: Twenty-three patients with diabetes mellitus and 27 control subjects participated in the study.

Nutrition in inflammatory bowel diseases.

The relationship between nutrition and inflammatory bowel disease (IBD) is a complex one, the evaluation and correction of nutritional deficits being integral part of therapy in these patients. The diet that consists in excessive consumption of meat, sugar, fats (with a higher 0 6 /o) 3 polyunsaturated fatty acids ratio) are factors involved in the epidemiology and pathogenesis of IBD. Malnutrition is present among most IBD patients, being the result of multiple mechanisms from digestive symptoms to inflammatory process, intestinal resection and administration of medications.

Extremely low-frequency electromagnetic fields cause DNA strand breaks in normal cells.

Background: Extremely low frequency electromagnetic fields aren't considered as a real carcinogenic agent despite the fact that some studies have showed impairment of the DNA integrity in different cells lines. The aim of this study was evaluation of the late effects of a 100 Hz and 5.6 mT electromagnetic field, applied continuously or discontinuously, on the DNA integrity of Vero cells assessed by alkaline Comet assay and by cell cycle analysis.

Synthesis and in vitro analysis of novel dihydroxyacetophenone derivatives with antimicrobial and antitumor activities.

Herein we report a feasible study concerning the design, syntheses and in vitro antimicrobial and antitumoral activities of some novel compounds with dihydroxyacetophenone (DA) moiety. An efficient and general method for the preparation of diazine with dihydroxyacetophenone (DDA) skeleton under conventional thermal heating (TH), microwave (MW) and ultrasounds (US) irradiation is presented. Antimicrobial and antitumoral tests prove that some dihydroxyacetophenone compounds (the brominated derivatives BrDA 3) have a significant biological activity.

Oligomerization of DDR1 ECD affects receptor-ligand binding.

Discoidin domain receptor 1 (DDR1) is a widely expressed receptor tyrosine kinase (RTK) which regulates cell differentiation, proliferation and migration and remodeling of the extracellular matrix. Collagen(s) are the only known ligand for DDR1. We have previously reported that collagen stimulation leads to oligomerization of the full length receptor.

Finite element analysis of traction force microscopy: influence of cell mechanics, adhesion, and morphology.

The interactions between adherent cells and their extracellular matrix (ECM) have been shown to play an important role in many biological processes, such as wound healing, morphogenesis, differentiation, and cell migration. Cells attach to the ECM at focal adhesion sites and transmit contractile forces to the substrate via cytoskeletal actin stress fibers. This contraction results in traction stresses within the substrate/ECM.

The prevalence of anaemia in patients with inflammatory bowel diseases in North-Eastern Romania.

Unlabelled: Anemia is a frequent complication of inflammatory bowel diseases (IBD). The main incriminated mechanisms are the iron deficiency and the chronic inflammation. The aim of this study was to determine the prevalence of anemia in IBD patients and to identify the main causes.

Multi-omic data integration links deleted in breast cancer 1 (DBC1) degradation to chromatin remodeling in inflammatory response.

This study investigated the dynamics of ubiquitinated proteins after the inflammatory stimulation of RAW 264.7 macrophage-like cells with bacterial lipopolysaccharide. Ubiquitination is a common protein post-translational modification that regulates many key cellular functions.

Similar problem in the activities of daily living but different experience: a qualitative analysis in six rheumatic conditions and eight European countries.

Objective: The aim of the present study was to compare and contrast the concepts of functioning in daily life which were important to patients with different rheumatological conditions.

Method: The study comprised a qualitative analysis of 44 focus groups in eight European countries, in 229 patients with fibromyalgia, hand osteoarthritis, psoriatic arthritis, rheumatoid arthritis, systemic lupus erythematosus and systemic sclerosis, using the World Health Organization, 2001 International Classification of Functioning, Disability and Health as a framework. Concepts and - where necessary - also sub-concepts and transcripts were combined and compared independently by two researchers who, in case of disagreement, achieved consensus through discussion.

Discoidin domain receptors: unique receptor tyrosine kinases in collagen-mediated signaling.

The discoidin domain receptors (DDRs) are receptor tyrosine kinases that recognize collagens as their ligands. DDRs display unique structural features and distinctive activation kinetics, which set them apart from other members of the kinase superfamily. DDRs regulate cell-collagen interactions in normal and pathological conditions and thus are emerging as major sensors of collagen matrices and potential novel therapeutic targets.

What is the impact of age on adult patients with inflammatory bowel disease?

Inflammatory bowel disease (IBD) is a chronic disease that affects both young adults and also the elderly. This article emphasises the particularities related to age in the epidemiology, diagnosis, natural course of the disease, prognosis and therapy of adult patients with IBD. Even though the main characteristics in geriatric populations with IBD may not differ much from those in younger patients, distinct problems exist.

The semi-quantitative calprotectin rapid test--is it useful in inflammatory bowel disease?

Aim: To assess the efficiency of the dosage of the semi-quantitative calprotectin rapid test in evaluating the activity of inflammatory bowel diseases.

Material And Methods: The prospective study included 87 patients with BII (50 with ulcerative colitis, 37 with Crohn disease) hospitalized between January 2011 - May 2012. The diagnosis was confirmed by colonoscopy and histological examination.

Quality of life in patients with ulcerative colitis.

Unlabelled: Patients with inflammatory bowel disease (IBD) have to live with the perspective of a potential disability, which may lead in time to impaired quality of life (QoL). In order to fully understand the impact of IBD on patients and their careers we need to quantify the QoL.

Aim: To evaluate HRQol in ulcerative colitis patients as opposed to the general population and to identify the significant changes of HRQoL in accordance with the specific progression of UC.

Rare types of diabetes mellitus.

Diabetes mellitus is a heterogenous disorder characterized by chronic hyperglycemia and induced by a large number of etiopathogenic conditions. Beside type 1 and type 2 diabetes, which account for almost 90% of all cases, practitioners may encounter patients with more infrequent forms of diabetes, as those induced by mutations of a single gene, atypical immune disorders or neonatal diabetes. Monogenic diabetes is represented by genetic disorders in the structure of the beta-cell (the MODY syndromes and the mutations of mitochondrial DNA) or in the insulin's action (type A insulin resistance syndrome, Rabson-Mendenhall syndrome, leprechaunism, lipodystrophies).

Diet and irritable bowel syndrome.

Background And Aims: Recent papers highlight the role of the diet in irritable bowel syndrome (IBS), but very few population-based studies have evaluated this. The aim of the study was to determine the prevalence of IBS in the general urban population and to evaluate the type of diet associated with IBS symptoms.

Methods: A randomized sample of subjects (n=300) from a general urban population in Romania selected from family doctors' patient lists was invited for interview in the doctor's office.

Loss of the Par3 polarity protein promotes breast tumorigenesis and metastasis.

Loss of epithelial organization is a hallmark of carcinomas, but whether polarity regulates tumor growth and metastasis is poorly understood. To address this issue, we depleted the Par3 polarity gene by RNAi in combination with oncogenic Notch or Ras(61L) expression in the murine mammary gland. Par3 silencing dramatically reduced tumor latency in both models and produced invasive and metastatic tumors that retained epithelial marker expression.

Extrahepatic complications of chronic cholestasis: current diagnosis and treatment.

Pruritus, fatigue and osteoporosis are the main symptoms of the extra hepatic manifestations of chronic cholestasis that affect patients' quality of life. Pruritus affects more often female patients, varies as intensity during a day and for longer period of time, typically can be localized on the palms of hands and soles of feet or can be generalized. Pruritus can be treated with anions resines exchange--cholestiramine, the pregnanne X receptor agonist Rifampicine, Naltrexone.

Infectious myelitis.

Infections are an uncommon but very important etiology of myelitis as a correct diagnosis would allow for timely treatment and recovery. The term "myelitis" is generally used to describe an inflammatory pathologic process affecting the spinal cord and causing an interruption of the ascending and descending pathways, and, therefore, partial or complete loss of function. The onset may be acute or subacute, and the etiology may be cumbersome to determine.

Myoferlin depletion in breast cancer cells promotes mesenchymal to epithelial shape change and stalls invasion.

Myoferlin (MYOF) is a mammalian ferlin protein with homology to ancestral Fer-1, a nematode protein that regulates spermatic membrane fusion, which underlies the amoeboid-like movements of its sperm. Studies in muscle and endothelial cells have reported on the role of myoferlin in membrane repair, endocytosis, myoblast fusion, and the proper expression of various plasma membrane receptors. In this study, using an in vitro human breast cancer cell model, we demonstrate that myoferlin is abundantly expressed in invasive breast tumor cells.

Evidence for a smooth onset of deformation in the neutron-rich Kr isotopes.

The neutron-rich nuclei 94,96Kr were studied via projectile Coulomb excitation at the REX-ISOLDE facility at CERN. Level energies of the first excited 2(+) states and their absolute E2 transition strengths to the ground state are determined and discussed in the context of the E(2(1)(+)) and B(E2;2(1)(+)→0(1)(+)) systematics of the krypton chain. Contrary to previously published results no sudden onset of deformation is observed.
