Immunochemical binding assays for detection and quantification of trace impurities in biotechnological production.

New, highly sensitive, biosensor concepts make it possible to assay biomacromolecules at concentrations that previously were far below the limit of detection. The previous generation of assays used in quality control situations during biotechnological production was designed primarily for monitoring target molecules, which typically appeared in high concentrations. Hence, novel analytical techniqu

The use (or misuse) of microsatellite allelic distances in the context of inbreeding and conservation genetics.

Abstract In line with inbreeding theory, genetic diversity at a set of molecular markers may explain variation in fitness-associated traits in partially inbred populations, and such associations will appear as 'genotype-fitness correlations'. An individual genetic diversity index specifically used for microsatellites is 'mean d(2)', i.e. the mean squared distance between alleles. The original hypo

A systematic review of the effectiveness of revascularization of the ulcerated foot in patients with diabetes and peripheral arterial disease

In several large recent observational studies, peripheral arterial disease (PAD) was present in up to 50% of the patients with a diabetic foot ulcer and was an independent risk factor for amputation. The International Working Group on the Diabetic Foot therefore established a multidisciplinary working group to evaluate the effectiveness of revascularization of the ulcerated foot in patients with d

The Pediatric Cataract Register (PECARE): analysis of age at detection of congenital cataract

Purpose: To analyse and discuss screening for the detection of congenital cataract in two Nordic countries, Denmark and Sweden. Methods: Until 2011, in Denmark, no guideline concerning screening for congenital cataract existed. Since 2011, Danish guidelines regarding eye examination include examination with a pencil light at age 5 weeks, whereas newborn red reflex examination using a handheld opht

Lies, Damned Lies, and Health Inequality Measurements: Understanding the Value Judgments.

Measuring and monitoring socioeconomic health inequalities are critical for understanding the impact of policy decisions. However, the measurement of health inequality is far from value neutral, and one can easily present the measure that best supports one's chosen conclusion or selectively exclude measures. Improving people's understanding of the often implicit value judgments is therefore import

Long-term outcome and MGMT as a predictive marker in 24 patients with atypical pituitary adenomas and pituitary carcinomas given treatment with temozolomide.

Context/Objective: Locally aggressive pituitary tumors (LAPT) and pituitary carcinomas respond poorly to conventional therapy and cytotoxic drugs. Temozolomide (TMZ) is an oral alkylating drug with good tolerability, approved for treatment of malignant gliomas. The experience of its use in pituitary tumors is limited. Design/Setting: We report on 24 patients with aggressive pituitary tumors (16 LA

Evaluating life: Working with ethical dilemmas in education for sustainable development

Codifications of human rights are widely understood as politically established instruments for evaluating human life. The call for such an apparatus emerges as a response to the age-old problem of social organization, constituting – in extension – a means by which to cope with the overall problem of survival. However, evaluating life is inherently problematic. It is problematic as it presupposes a

The Associations Between Finger Length Pattern, Osteoarthritis, and Knee Injury: Data From the Framingham Community Cohort

Objective. To investigate the associations of index finger-to-ring finger (2D:4D) length ratio with radiographic knee and hand osteoarthritis (OA), previous knee injury, and meniscal lesions in the general population. Methods. We measured the length of the right second and fourth phalangeal and metacarpal bones on hand radiographs from 1,020 randomly recruited subjects (ages 51-92 years). Knee rad

CD44 enhances invasion of basal-like breast cancer cells by upregulating serine protease and collagen-degrading enzymatic expression and activity

Introduction: Basal-like breast cancers (BL-BCa) have the worst prognosis of all subgroups of this disease. Hyaluronan (HA) and the HA receptor CD44 have a long-standing association with cell invasion and metastasis of breast cancer. The purpose of this study was to establish the relation of CD44 to BL-BCa and to characterize how HA/CD44 signaling promotes a protease-dependent invasion of breast c

Bortezomib consolidation after autologous stem cell transplantation in multiple myeloma: a Nordic Myeloma Study Group randomized phase 3 trial

The Nordic Myeloma Study Group conducted an open randomized trial to compare bortezomib as consolidation therapy given after high-dose therapy and autologous stem cell transplantation (ASCT) with no consolidation in bortezomib-naive patients with newly diagnosed multiple myeloma. Overall, 370 patients were centrally randomly assigned 3 months after ASCT to receive 20 doses of bortezomib given duri

Factors related to the return to work potential in persons with severe mental illness.

Abstract Objective: This cross-sectional study aimed at investigating the relationship between the return to work potential, according to the Worker Role Interview (WRI) assessment, and clinical characteristics and level of empowerment and occupational engagement among persons with severe mental illness who express their own interest in working. Methods: 120 participants entered the study. The WRI

Within-plant isoprene oxidation confirmed by direct emissions of oxidation products methyl vinyl ketone and methacrolein

Isoprene is emitted from many terrestrial plants at high rates, accounting for an estimated 1/3 of annual global volatile organic compound emissions from all anthropogenic and biogenic sources combined. Through rapid photooxidation reactions in the atmosphere, isoprene is converted to a variety of oxidized hydrocarbons, providing higher order reactants for the production of organic nitrates and tr

Off-the-shelf options for juxtarenal and pararenal aortic aneurysm

In patients unsuitable for standard, infrarenal endovascular aneurysm repair (EVAR) due to an inadequate or inappropriate infrarenal neck, various options have been proposed to achieve a suitable endovascular repair. The primary objective in this setting is to move the endograft sealing zone to a healthier, more cranial segment of the aorta. The need for a solution for problematic proximal neck an

The Endurance/Perdurance Controversy is No Storm in a Teacup

Several philosophers have maintained in recent years that the endurance/perdurance debate is merely verbal: these prima facie distinct theories of objects’ persistence are in fact metaphysically equivalent, they claim. The present paper challenges this view. Three proposed translation schemes (those set forth by Miller 2005; McCall and Lowe 2006; Hirsch 2009) are examined; all are shown to be faul

Haemophilia Care in Europe: the ESCHQoL study

The aim of this study was to determine the clinical conditions of patients with haemophilia within Europe as recommended by the European Commission. In this multicentre, cross-sectional, ambispective study, conducted within 21 European countries patients' clinical data were collected, amongst others haemophilia type, severity, treatment pattern, use of factor products, bleeding, orthopaedic joint

Vertical "III-V" V-Shaped Nanomembranes Epitaxially Grown on a Patterned Si[001] Substrate and Their Enhanced Light Scattering

We report on a new form of III-IV compound semiconductor nanostructures growing epitaxially as vertical V-shaped nanomembranes on Si(001) and study their light-scattering properties. Precise position control of the InAs nanostructures in regular arrays is demonstrated by bottom-up synthesis using molecular beam epitaxy in nanoscale apertures on a SiO2 mask. The InAs V-shaped nanomembranes are foun
