We present a spatiotemporal analysis of high harmonic generation, showing evidence for the presence of several quantum path contributions to the atomic dipole moment. We show that the harmonic radiation can largely be described as a sum of two fields having a phase proportional to the intensity of the generating field. We compare our results to recent experimental results demonstrating this separa

We report measurements and calculations of the polarization state of high-order harmonics generated by a 790-nm Ti:sapphire laser. The problem of completely characterizing the polarization state of a partially polarized radiation in the XUV range is discussed in detail. The comparison between several gases, xenon, argon and neon, and different orders, from the 17th to the 33rd, shows that the rota

An experimental system has been developed to verify the possibility of detecting flow activity using a technique called ultrasound Doppler vector tomography. A tomography algorithm is used to reconstruct blood flow vector fields using data from computer-controlled ultrasound continuous-wave Doppler scanning equipment. The result is a picture in which the brightness variations represent the reconst

For reprint orders, please contact reprints@ future-science. com stakeholders, markets and institutions. Experience shows that straightforward regulation can be justifiable and effective in some areas (eg, building codes and appliance standards), benefit sharing schemes are often important to ensure stakeholder buy-in (eg, local acceptance for wind power) and public–private partnerships can be imp

Cystatin C and cathepsins could play a role in almost all processes involved in atherosclerotic lesion formation by their degradation of extracellular matrix proteins and apolipoprotein B100, the protein moiety of LDL. Several cysteine cathepsins are upregulated in human lesions accompanied by a decrease in cystatin C, the major inhibitor of cysteine cathepsins. Recent research show that atheroscl

BACKGROUND: Higher operative risks after pneumonectomy for non-small cell lung cancer (NSCLC) have been reported after neoadjuvant chemotherapy or radiotherapy, or both. Patients who underwent pneumonectomy for NSCLC were evaluated for effect of neoadjuvant treatment on mortality and morbidity, especially bronchopleural fistula. METHODS: Between 1996 and 2003, 130 consecutive patients underwent pn

Abstract Background: The metabolic syndrome is regarded as an important risk factor for diabetes mellitus and cardiovascular disease. Metabolic syndrome could be associated with impaired quality of life (QoL). Methods: The Women's Health in the Lund Area (WHILA) project covers 10,766 women born between December 2, 1935, and December 1, 1945, living in the Lund area, of Sweden by December 1, 1995.

The epidemiology of systemic lupus erythematosus (SLE) within a defined region in southern Sweden was studied during the time period 1981-2006. Furthermore, whether the phenotypic expression of SLE changed during the study period was investigated.

The liver is a common location of both primary and secondary malignancies. For unresectable liver cancer, many local ablative therapies have been developed. These include e.g., percutaneous ethanol injection (PEI), percutaneous acetic acid injection, radiofrequency ablation (RFA), cryoablation, microwave ablation, laser-induced thermotherapy, and high-intensity focused ultrasound. RFA has recently

PURPOSE: miRNAs play a prominent role in a variety of physiologic and pathologic biologic processes, including cancer. For rectal cancers, only limited data are available on miRNA expression profiles, whereas the underlying genomic and transcriptomic aberrations have been firmly established. We therefore, aimed to comprehensively map the miRNA expression patterns of this disease. EXPERIMENTAL DE

Stroke-induced neurogenesis originates from a neural stem cell (NSC) niche in subventricular zone (SVZ). In mice, NSCs are concentrated in a so-called "neurogenic spot" in the lateral angle area of SVZ. We aimed to identify the "neurogenic spot" in the rat SVZ and to characterize the cellular changes in the ependymal cell compartment in this area at different time points after middle cerebral arte

OBJECTIVE: To compare neonatal outcome of blastocyst and cleavage stage embryo transfers after IVF. DESIGN: Register study. PATIENT(S): Treatments reported from all Swedish IVF clinics. INTERVENTION(S): None. SETTING: Births recorded in the Swedish Medical Birth Register after IVF performed, 2002-2006. MAIN OUTCOME MEASURE(S): Some neonatal characteristics were compared in 1,311 infants born after

BACKGROUND: Risk of coronary heart disease (CHD) in cancer patients has not been thoroughly investigated. The aim of the present study was to examine whether there is an association between cancer and first hospitalisation for CHD. METHODS: All individuals in Sweden with a diagnosis of cancer between 1st January 1987 and 31st December 2008 were followed for first hospitalisation for CHD. The refer

The identification of serum biomarkers for the diagnosis of inflammatory bowel diseases able to reduce the need for invasive tests represents a major goal in their therapy and follow-up. We report here a methodological approach for the evaluation of specific changes in the serum peptides abundance in healthy (H) and Crohn's disease (CD) subjects, based on a label-free LC ESI/Q-TOF differential mas

PURPOSEOur aim was to assess the impact of cigarette smoking on the risk of the tumors classified by the International Agency for Research on Cancer as causally associated with smoking, referred to as tobacco-related cancers (TRC). METHODSThe study population included 441,211 participants (133,018 men and 308,193 women) from the European Prospective Investigation Into Cancer and Nutrition. We inve
