Well-differentiated hepatocellular carcinoma (HCC) may resemble benign liver lesions on initial diagnostic work-up. The validity of surgical resection for preoperatively unclear liver lesions was investigated in this study.

Objective: Primary hyperparathyroidism (PHPT) is associated with cardiovascular morbidity and premature death but the underlying mechanisms are incompletely understood. The aim of this study was to investigate if adrenergic dysfunction may be a contributing factor. Patients and methods: Forty-nine patients with mild PHPT (serum calcium 2.7 ± 0.1 mmol/L) and 48 control subjects, matched for age an

We report on a forward RNAi screen in primary human hematopoietic stem and progenitor cells, using pooled lentiviral shRNA libraries deconvoluted by next generation sequencing. We identify MAPK14/p38α as a modulator of ex vivo stem cell proliferation and show that pharmacological inhibition of p38 dramatically enhances the stem cell activity of cultured umbilical cord blood derived hematopoietic c

Absorption (mu (a)) and reduced scattering (mu (s)') spectra of turbid media were quanti fied with a noncontact imaging approach based on a Fourier-transform interferometric imaging system (FTIIS). The FTIIS was used to collect hyperspectral images of the steady-state diffuse reflectance from turbid media. Spatially resolved reflectance data from Monte Carlo simulations were fitted to the recorded

This paper presents a systematic approach to robust preconditioning for gradient-based nonlinear inverse scattering algorithms. In particular, one- and two-dimensional inverse problems are considered where the permittivity and conductivity profiles are unknown and the input data consist of the scattered field over a certain bandwidth. A time-domain least-squares formulation is employed and the inv

Objectives: The aim of the study was to further psychometrically evaluate the instrument "Pain Impact Inventory" (PII) in various subgroups. Methods: The sample comprised 384 persons (aged between 18 and 102 years) who reported chronic pain. The instrument PII was evaluated in terms of construct validity as well as reliability. The instrument's validity was investigated through corrected item-tota

Background: Levosimendan has been proposed as an attractive alternative to adrenergic agents for the treatment of sepsis-induced heart failure and haemodynamic derangements. Its use in this setting is, however, still not well investigated. The aim of this study was to test the hypothesis that levosimendan is able to attenuate endotoxin-induced pulmonary hypertension and improve myocardial function

BACKGROUND: The CHADS(2) score (C, congestive heart failure [CHF]; H, hypertension [HT]; A, age ≥75 y; D, diabetes mellitus; S(2) , prior stroke or transient ischemic attack) is used to assess the risk of ischemic stroke in patients with atrial fibrillation (AF). However, its role in patients without documented AF is not well explored. HYPOTHESIS: The goal of the current study was to explore if th

Continuous administration of levodopa-carbidopa intestinal gel (carbidopa-levodopa enteral suspension) through a percutaneous endoscopic gastrojejunostomy is a treatment option for advanced Parkinson disease (PD) patients with motor fluctuations resistant to standard oral medications. Safety data from 4 prospective studies were integrated to assess the safety of this therapy.

Abstract Through the use of chimeric CXCR4/CCR5 receptors we have previously shown that CCR5-tropic (R5) HIV-1 isolates acquire a more flexible receptor use over time, and that this links to a reduced viral susceptibility to inhibition by the CCR5 ligand RANTES. These findings may have relevance with regards to the efficacy of antiretroviral compounds that target CCR5/virus interactions. Compartme

Gene therapy of solid cancers has been severely restricted by the limited distribution of vectors within tumors. However, cellular vectors have emerged as an effective migratory system for gene delivery to invasive cancers. Implanted and injected multipotent mesenchymal stromal cells (MSCs) have shown tropism for several types of primary tumors and metastases. This capacity of MSCs forms the basis

OBJECTIVE: To examine the number of trials needed to achieve performance stability of the Timed Up & Go (TUG) test using a standardized walking aid in patients with hip fracture who are allowed full weight bearing (FWB). DESIGN: Prospective methodologic study. SETTING: An acute 14-bed orthopedic hip fracture unit. PARTICIPANTS: Patients (N=122; 89 women, 33 men) with hip fracture wit

Study Type - Diagnostic (case series) Level of Evidence 4 What's known on the subject? and What does the study add? It is well known that CIS is a major risk factor for muscle-invasive bladder cancer and that this entity can be difficult to diagnose. Taking cold-cup mapping biopsies from different areas of the bladder (BMAP) is commonly used in patients at risk of harbouring CIS. The diagnostic ac

Endovascular repair has become the primary treatment option for abdominal aortic aneurysms over the past decade. The favorable results as well as technical evolution have led endovascular repair to include fenestrated and branched technology for complex juxtarenal, suprarenal, and thoracoabdominal aneurysms. These grafts are, however, extensively customized and patient tailored at present precludi

In this letter, a magnetic dipole (M-dipole) and an electric dipole (E-dipole) are designed to form a collocated polarization-diversity-based dual-antenna system. The M-dipole is a modified shielded loop with multiple feed, and the E-dipole is a traditional λ/2 dipole. Measured results show that both radiators have ideal impedance matching and port isolation and identical omnidirectional pattern w

persson e.k., fridlund b., kvist l.j. & dykes a.-k. (2010) Mothers' sense of security in the first postnatal week: interview study. Journal of Advanced Nursing. ABSTRACT: Aim. This paper is a report of a study of factors which influence mothers' sense of security during the first postnatal week. Background. Mothers' sense of security the first postnatal week is not thoroughly elucidated in the

Previous family and twin studies have indicated that Graves' disease has a heritable component. Family studies have also shown that some autoimmune disease cluster in families and genetic studies have been able to show shared susceptibility genes. In the present nation-wide study we describe familial risk for Graves' disease among parents and offspring, singleton siblings, twins and spouses with r
