Objective: To test the hypotheses that the empirical consideration of objective person-environment fit in the home environment is a stronger predictor of indoor falls among older adults than the assessment of environmental barriers only, and that perceived aspects of home play a role as predictors for falls.Design: Survey study with data collection at home visits, followed up by self-reports about

Neural stem cells (NSCs) in the adult rat subventricular zone (SVZ) generate new striatal neurons during several months after ischemic stroke. Whether the microglial response associated with ischemic injury extends into SVZ and influences neuroblast production is unknown. Here, we demonstrate increased numbers of activated microglia in ipsilateral SVZ concomitant with neuroblast migration into the

Objective: The present study evaluates the impact of prosthesis-patient mismatch (PPM) on left ventricular remodelling following aortic valve replacement (AVR) for severe aortic insufficiency. Methods: In this study, 230 patients undergoing aortic valve surgery were divided into two groups depending on whether or not they exhibited PPM. Postoperative left ventricular (LV) dimensions and function w

Voiding is mediated by muscarinic receptors in urinary bladder smooth muscle cells. Lipid rafts and caveolae are cholesterol enriched membrane domains that modulate the activity of G protein-coupled receptors and second messenger systems. Conflicting findings regarding sensitivity of muscarinic signalling to cholesterol desorption, which perturbs lipid rafts and caveolae, have been reported, and n

OBJECTIVE: Polymorphonuclear leukocytes (PMN) with autoantibody-coated engulfed necrotic cell material (NC) are frequently seen in systemic lupus erythematosus (SLE). We evaluated the roles of complement, different antihistone antibodies (anti-H ab), and oxidative burst in the phagocytosis of NC by PMN, as well as association to disease activity and clinical phenotype in SLE. METHODS: ELISA an

ABSTRACT Objectives: This study was designed to assess endovascular intervention for central venous cannulation in patients with vascular occlusion after previous catheterization. Methods: Patients referred for endovascular management of central venous occlusion during a 42-month period were identified from a regional endovascular database, providing prospective information on techniques and clini

The highly malignant brain tumor, glioblastoma multiforme, is difficult to totally resect without aid due to its infiltrative way of growing and its morphological similarities to surrounding functioning brain under direct vision in the operating field. The need for an inexpensive and robust real-time visualizing system for resection guiding in neurosurgery has been formulated by research groups al

Hemoglobin released from damaged erythrocytes is a major pro-oxidant, generator of free radicals and inflammatory mediator. Huntington's disease is an inherited neurodegenerative disorder characterized by both neurological and systemic abnormalities, in which oxidative stress has been suggested as a possible pathogenic mechanism. In the present work we have investigated levels of hemoglobin and ma

Although several studies have reported on the anti-tumoural properties exerted by 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG-CoAR) inhibitors (statins), the in vivo expression of HMG-CoAR in human cancer has been considerably less investigated. In our study, we examined the immunohistochemical expression of HMG-CoAR in 511 incident breast cancers within the Malmö Diet and Cancer Study in

PURPOSE OF REVIEW: Dissecting the genetics of complex polygenic diseases in which environmental factors interact with genetic variants in the predisposition to the disease has not been a trivial task and success has been limited. The purpose of this review is to provide insights into recent advances in genetics of type 2 diabetes. RECENT FINDINGS: In the past year, together the consortia of severa

Neuropeptide Y (NPY) is widely expressed throughout the CNS and exerts a number of important physiological functions as well as playing a role in pathological conditions such as obesity, anxiety, epilepsy, chronic pain and neurodegenerative disorders. In this review, we highlight some of the recent advances in our understanding of NPY biology and how this may help explain not only its role in heal

In the process of obtaining a driver's license, a healthy 28year old man presented increased levels of disialo-transferrin (TF) (approx. 20%, ref. value<2) by HPLC analysis of TF isoforms (%CDT), while other markers of excessive alcohol consumption (PEth, MCV and γ-GT) were in the normal range. The objective of this study was to determine the cause of the increased %CDT levels.

PURPOSE: Human epidermal growth factor receptor 2 (HER2) gene amplification or protein overexpression (HER2 positivity) defines a clinically challenging subgroup of patients with breast cancer (BC) with variable prognosis and response to therapy. We aimed to investigate the heterogeneous biologic appearance and clinical behavior of HER2-positive tumors using molecular profiling. PATIENTS AND METHO

Background: Linalool is a common fragrance terpene that, in pure form, is not allergenic or is a very weak allergen. However, linalool autoxidizes on air exposure, and the oxidation products can cause contact allergy. In a Swedish study, oxidized linalool 6.0% in petrolatum (pet.) gave 5% positive patch test reactions in 2500 dermatitis patients. Objectives: To investigate whether oxidized linal

OBJECTIVES: To analyse 80-kVp 16-MDCT in patients with clinically suspected pulmonary embolism (PE) and diminished renal function after a reduction in dose of contrast medium (CM) from 200 to 150 mg I/kg. METHODS: Fifty patients with suspected PE and glomerular filtration rate (GFR) less than 50 mL/min underwent 80-kVp 16-MDCT with 150 mg I/kg. Mean density/image noise (1 standard deviation) was m

The aim of this study was to determine whether educational length affects prostate-specific antigen (PSA) testing and the time to prostate biopsy for men with raised PSA values.

OBJECTIVE:: The primary aim of this study was to evaluate if the use of proton pump inhibitors (PPIs) reduced the prevalence of benign anastomotic strictures after uncomplicated esophagectomies with gastric tube reconstruction and circular stapled anastomoses. SUMMARY BACKGROUND DATA:: Benign anastomotic strictures are associated with anastomotic leaks or conduit ischemia. Also patients without th

Weaponry and color badges are commonly theorized to function as visual signals of aggressiveness or fighting ability. However, few studies have supported a signaling function of weaponry, and the role of color in invertebrate competitive interactions remains virtually unexplored. Jumping spiders (Salticidae) make excellent invertebrate models for studying weaponry and color because males of many s
