The sensory quality of broccoli stored in modified atmosphere packages was studied. Oriented polypropylene (OPP), polyvinyl chloride (PVC) and low-density polyethylene (LDPE) were used as packaging materials. The LDPE contained an ethylene-absorbing sachet. The samples were stored for I week, either at a constant temperature of 10 degreesC or for 3 days at 4 degreesC, followed by 4 days at 10 degr

Distinct morphologic and clinical features associated with specific chromosomal abnormalities have been described in subgroups of myelodysplastic syndromes (MDS), which often are losses or gains and only rarely translocations. Among 103 consecutive MDS patients diagnosed and karyotyped at the Albert-Ludwigs University of Freiburg (ALU) between 1993 and 1999, two chronic myelomonocytic leukemias (C

We report the cryo-EM structure of bacteriophage lambda and the mechanism for stabilizing the 20-angstrom-thick capsid containing the dsDNA genome. The crystal structure of the HK97 bacteriophage capsid fits most of the T = 7 lambda particle density with only minor adjustment. A prominent surface feature at the 3-fold axes corresponds to the cementing protein gpD, which is necessary for stabilizat

Introduction and presentation to the six essays that encompasses the issue at hand.

Autoantibodies to glutamate decarboxylase 65 (GAD65Ab) are commonly believed to be a major characteristic for type 1 diabetes (T1D). We investigated the presence of GAD65Ab in healthy individuals (n = 238) and first-degree relatives (FDRs) of T1D patients (n = 27) who tested negative for GAD65Ab in conventional RIAs. Sera were applied to affinity columns coated with GAD65-specific mAbs to absorb a

New diagnostic criteria for multiple sclerosis integrating magnetic resonance image assessment with clinical and other paraclinical methods were introduced in 2001. The "McDonald Criteria" have been extensively assessed and used since 2001. New evidence and consensus now strengthen the role of these criteria in the multiple sclerosis diagnostic workup to demonstrate dissemination of lesions in tim

Asporin, a novel member of the leucine-rich repeat family of proteins, was partially purified from human articular cartilage and meniscus. Cloning of human and mouse asporin cDNAs revealed that the protein is closely related to decorin and biglycan. It contains a putative propeptide, 4 amino-terminal cysteines, 10 leucine-rich repeats, and 2 C-terminal cysteines. In contrast to decorin and biglyca

The uncertainties and sources of variation in projected impacts of climate change on agriculture and terrestrial ecosystems depend not only on the emission scenarios and climate models used for projecting future climates, but also on the impact models used, and the local soil and climatic conditions of the managed or unmanaged ecosystems under study. We addressed these uncertainties by applying di

In this article we develop an approach to deformations of the Witt and Virasoro algebras based on sigma-derivations. We show that sigma-twisted Jacobi type identity holds for generators of such deformations. For the sigma-twisted generalization of Lie algebras modeled by this construction, we develop a theory of central extensions. We show that our approach can be used to construct new deformation

Currently in Europe as well as in the United States, an increasing proportion of very old people remain living in their homes despite declines in physical and mental health. Together with the fact that the population of very old people is rapidly increasing (Mathers, Sadana, Salamon, Murray, Lopez, 2001; United Nations Development Programme, 2001), this poses new challenges to societal planning an

With the use of electrogoniometers wrist positions and movements were measured in 13 milkers while working in a modern rotary milking system. The rotary system put considerable demands on the wrists and hands regarding both velocities and repetitiveness. Values were found close to those described in other repetitive industrial work with high risk of wrist and hand disorders. For the right hand the

Background When this study was initiated, no previous studies comparing methotrexate and ciclosporin for moderate to severe plaque psoriasis had been performed. Objectives To compare the effectiveness, quality of life and side-effects of methotrexate and ciclosporin treatments in a context reflecting normal clinical practice. Methods Eighty-four patients with moderate to severe plaque psoriasis

We examine whether it is a psychosocial or an economic need for employment that affects mental health among the unemployed. The relevance of both aspects are examined, concentrating on two measures of each dimension. Two perspectives of work involvement - the degree of connection to working life and the perceived employment commitment and two perspectives on financial situation economic security a

Background aims. Advanced therapy medicinal products (ATMP) are gene therapy, somatic cell therapy or tissue-engineered products regulated under (EC) No. 1394/2007 to ensure their free movement within the European Union while guaranteeing the highest level of health protection for patients. Academic good manufacturing practice (GMP) centers are major contributors in the development of ATMPs and th

An increasing number of individuals seek genetic counseling and hereby learn about hereditary cancer in the family. Lynch syndrome is associated with an inherited high risk for colorectal and gynecological cancer, but knowledge about how family members at risk perceive their situation is limited. We used the national Danish HNPCC register to collect data on self-concept from 413 individuals with L

Background: Sentinel lymph node (SLN) biopsy has replaced axillary lymph node dissection (ALND) as the standard axillary staging procedure in breast cancer. Follow-up studies in SLN-negative women treated without ALND report low rates of axillary recurrence, but most studies have short follow-up, and few are multicentre studies. Methods: Between September 2000 and January 2004, patients who were S

Pesaran and Yamagata (Pesaran, M.H., Yamagata, T., Testing slope homogeneity in large panels, Journal of Econometrics 142, 50–93, 2008) propose a test for slope homogeneity in large panels, which has become very popular in the literature. However, the test cannot deal with the practically relevant case of heteroskedastic and/serially correlated errors. The present note proposes a generalized test

On average, airborne aerosol particles cool the Earth's surface directly by absorbing and scattering sunlight and indirectly by influencing cloud reflectivity, life time, thickness or extent. Here we show that over the central Arctic Ocean, where there is frequently a lack of aerosol particles upon which clouds may form, a small increase in aerosol loading may enhance cloudiness thereby likely cau

To detect and avoid collisions, animals need to perceive and control the distance and the speed with which they are moving relative to obstacles. This is especially challenging for swimming and flying animals that must control movement in a dynamic fluid without reference from physical contact to the ground. Flying animals primarily rely on optic flow to control flight speed and distance to obstac
