Rapid development of nanotechnologies and their applications in clinical research have raised concerns about the adverse effects of nanoparticles (NPs) on human health and environment. NPs can be directly taken up by organs exposed, but also translocated to secondary organs, such as the central nervous system (CNS) after systemic- or subcutaneous administration, or via the olfactory system. The CN

The article discusses the background to the erection of the huge church tower in Bjälbo, Östergötland, Sweden. It also focuses on medieval women as founders of churches. The author maintains that new dendrochronological dating of the tower could mean that founder of this building piece was not one of the male members of the important Bjälbo dynasty, but Ingrid Ylva the mother of Birger Jarl.

A systematic set of single-pass full penetration friction stir bead-on-plate and butt-welds in HSLA-65 steel were produced using a range of different traverse speeds (50 to 500 mm/min) and two tool materials (W-Re and PCBN). Microstructural analysis of the welds was carried out using optical microscopy, and hardness variations were also mapped across the weld-plate cross sections. The maximum and

A lyotropic nonionic lamellar system composed of pentaethyleneglycol mono n-dodecyl ether and D(2)O was studied using natural abundance (13)C NMR under magic-angle spinning. Applying a two-dimensional recoupling method proposed by Dvinskikh (R-PDLF), (1)H-(13)C dipolar couplings were estimated over a range of temperatures (300-335 K), thus enabling analysis of structural changes in the liquid crys

Detection of active tuberculosis (TB) before antiretroviral therapy (ART) initiation is important, but optimal diagnostic methods for use in resource-limited settings are lacking. We assessed the prevalence of TB, evaluated the diagnostic yield of Xpert MTB/RIF in comparison with smear microscopy and culture, and the impact of Xpert results on clinical management in HIV-positive adults eligible fo

Objective To elucidate psychosexual problems in women referred for colposcopy after an abnormal cervical smear and a 6-month and 2-year follow up. Design Prospective study. Setting Department of Gynaecology, Malmö University Hospital, Sweden. Population One hundred consecutive women referred for colposcopy for the first time subsequent to receiving notification of an abnormal cervical smear. M

Transcription factors involved in the specification and differentiation of neurons often continue to be expressed in the adult brain, but remarkably little is known about their late functions. Nurr1, one such transcription factor, is essential for early differentiation of midbrain dopamine (mDA) neurons but continues to be expressed into adulthood. In Parkinson's disease, Nurr1 expression is dimin

Purpose: The aim was to investigate outcomes of powered wheelchair and scooter interventions after 4-months and 1-year use regarding need for assistance when moving around, frequency of mobility-related participation, easiness/difficulty in mobility during participation, and number of participation aspects performed in everyday life. Method: The study was a prospective cohort study, using an instr

BACKGROUND AND PURPOSE: The effect of age on the distribution of morphine and morphine-3-glucuronide (M3G) across the blood-brain barrier (BBB) was studied in a sheep model utilizing intracerebral microdialysis. The effect of neonatal asphyxia on brain drug distribution was also studied.EXPERIMENTAL APPROACH: Microdialysis probes were inserted into the cortex, striatum and blood of 11 lambs (127 g

BACKGROUND: Acrylamide, a probable human carcinogen, is formed from the amino acid asparagine and reducing sugars when potato products are processed at high temperatures. This is a two-year study on five Swedish-grown potato clones, two of which are adapted to cold storage. The clones represented a wide range of precursor concentrations: asparagine, 3.7-15.3 mg g-1; reducing sugars, 0.9-14.9 mg g-

Background: Cadmium (Cd) and lead (Pb) are hypothesised to be risk factors for non-Hodgkin's lymphoma (NHL), a group of haematological malignancies with a suspected environmental aetiology. Within the EnviroGenoMarkers study we utilised pre-diagnostic erythrocyte concentrations of Cd and Pb to determine whether exposure was associated with risk of B-cell NHL and multiple myeloma. Methods: 194 inci

Although it has been shown that aggrecanases are involved in aggrecan degradation, the role of MMP (matrix metalloproteinase) aggrecanolysis is less well studied. To investigate MMP proteolysis of human aggrecan, in the present study we used neoepitope antibodies against MMP cleavage sites and Western blot analysis to identify MMP-generated fragments in normal and OA (osteoarthritis/osteoarthritic

In Papers One through Six we have investigated the function and integration of “new” neurons – new neurons born from neural stem cells in the adult brain, and new neurons in the sense that they were generated from fibroblasts. Papers One and Two focused on the new neurons generated from neural stem cells in the SVZ and SGZ after pathological insults. We investigated how the newly generated neuro

Portal venous system thrombosis (PVST) is a rare, potentially fatal complication after pancreatic resection. The aim of this study was to assess the incidence, presenting symptoms, management, and treatment of PVST in a large cohort of patients. Prospectively collected data on patients undergoing pancreatic resection between 1997 and 2009 were reviewed retrospectively. Preoperative and postoperati
