Changing clinical presentation of angiosarcomas after breast cancer: from late tumors in edematous arms to earlier tumors on the thoracic wall.

Angiosarcoma is a rare complication of breast cancer treatment. In order to define predictors, clinical presentation, and outcome, we characterized a population-based 50-year cohort of angiosarcomas after breast cancer. Clinical data were collected from all females with previous breast cancer who developed angiosarcomas/lymphangiosarcomas on the thoracic wall/upper extremity between 1958 and 2008

Compression of the lower trunk of the brachial plexus by a cervical rib in two adolescent girls: case reports and surgical treatment.

ABSTRACT: Presence of a cervical rib in children is extremely rare, particularly when symptoms of compression of the lower trunk of the brachial plexus occur. We present two cases with such a condition, where two young girls, 11 and 16 years of age were treated by resection of the cervical rib after a supraclavicular exploration of the lower trunk of the brachial plexus. The procedure led to succe

Physical attractiveness stereotype and memory.

Rasmussen, A. & Rohner, J.-C. (2011). Physical attractiveness stereotype and memory. Scandinavian Journal of Psychology. Three experiments examined explicit and implicit memory for information that is congruent with the physical attractiveness stereotype (i.e. attractive-positive and unattractive-negative) and information that is incongruent with the physical attractiveness stereotype (i.e. at

Comparison of patients undergoing enhanced external counterpulsation and spinal cord stimulation for refractory angina pectoris.

INTRODUCTION: As more patients survive coronary events, the prevalence of patients with refractory angina pectoris is increasing. The aim was to evaluate the effects of enhanced external counterpulsation (EECP) and spinal cord stimulation (SCS) and compare with optimal medically treated patients with refractory angina. METHODS: 153 patients with refractory angina were treated with either EECP, SCS

Globalization, transparency and economic growth: The vulnerability of Chinese firms to macroeconomic shocks

The process of globalization encompasses economic and financial integration. The abolition of capital controls and the dismantling of barriers of different kinds will expose previously sheltered companies to shocks originating in the global economic arena. Policymakers in already globalized countries have learned that market participants should be prepared in due time to meet the new exposure to f

Stored energies in electric and magnetic current densities for small antennas

Electric and magnetic currents are essential to describe electromagnetic-stored energy, and the associated antenna Q and the partial directivity to antenna Q-ratio, D/Q, for arbitrarily shaped structures. The upper bound of previous D/Q results for antennas modelled by electric currents is accurate enough to be predictive. This motivates us to develop the analysis required to determine upper and/o

Ungdomsarbetslösheten - om övergångsregimer, institutionell förändring och socialt kapital

Popular Abstract in Swedish Varför är arbetslösheten bland ungdomar i Sverige tre gånger högre än arbetslösheten bland 25-64 åringar? Har kontakter och nätverk betydelse för ungdomsarbetslösheten? Den tes som drivs i denna avhandling menar att kontakter i form av överbryggande socialt kapital har betydelse för ungdomars möjlighet att få jobb och att ungdomars brist på socialt kapital leder till atYouth unemployment in Sweden has reached record levels during the first decade of the 21st century. In 1970, the unemployment rate for 20-24 year olds was approximately 2%. Now, forty years later, this rate has risen to 20%. Relative youth unemployment (youth unemployment in relation to unemployment for the 25-64 year olds) has also risen. Today, the unem¬ployment rate for 20-24 year olds is three

Recurrent gross mutations of the PTEN tumor suppressor gene in breast cancers with deficient DSB repair

Basal-like breast cancer (BBC) is a subtype of breast cancer with poor prognosis1, 2, 3. Inherited mutations of BRCA1, a cancer susceptibility gene involved in double-strand DNA break (DSB) repair, lead to breast cancers that are nearly always of the BBC subtype3, 4, 5; however, the precise molecular lesions and oncogenic consequences of BRCA1 dysfunction are poorly understood. Here we show that h

Mitogen-activated protein kinases in the porcine retinal arteries and neuroretina following retinal ischemia-reperfusion.

PURPOSE: The aim of the present study was to examine changes in the expression of intracellular signal-transduction pathways, specifically mitogen-activated protein kinases, following retinal ischemia-reperfusion. METHODS: Retinal ischemia was induced by elevating the intraocular pressure in porcine eyes, followed by 5, 12, or 20 h of reperfusion. The results were compared to those of the sham- op
