Micro-climate determines oviposition site selection and abundance in the butterfly Pyrgus armoricanus at its northern range margin

1. Knowledge about species habitat requirements is important when designing conservation strategies as well as for predicting species distributions. For herbivorous insects, insights in oviposition preferences can provide important information on their habitat requirements. 2. The oviposition preferences of Oberthür's Grizzled Skipper butterfly Pyrgus armoricanus Oberthür at its northern range bou

Multi-proxy identification of the Laschamp geomagnetic field excursion in Lake Pupuke, New Zealand

We present palaeomagnetic and cosmogenic radionuclide records of the Laschamp geomagnetic excursion in Lake Pupuke, a maar lake in Auckland, New Zealand. Laschamp was identified by a combination of relative palaeointensity, (10)Be and (14)C data from the lake sediments and represents the first such record from the Southern Hemisphere. Despite the high organic carbon content, which causes relativel

InAs hole inversion and bandgap interface state density of 2 x 10(11) cm(-2) eV(-1) at HfO2/InAs interfaces

High-k/InAs interfaces have been manufactured using InAs surface oxygen termination and low temperature atomic layer deposition of HfO2. Capacitance-voltage (C-V) curves revert to essentially classical shape revealing mobile carrier response in accumulation and depletion, hole inversion is observed, and predicted minority carrier response frequency in the hundred kHz range is experimentally confir

The nuclear localization of γ-tubulin is regulated by SadB-mediated phosphorylation.

γ-tubulin is an important cell division regulator that arranges microtubule assembly and mitotic spindle formation. Cytosolic γ-tubulin nucleates α- and β-tubulin in a growing microtubule by forming the ring-shaped protein complex γTuRC. Nuclear γ-tubulin also regulates S-phase progression by moderating the activities of E2Fs. The mechanism that regulates localization of γ-tubulin is currently unk

Propionibacterium acnes as an etiological agent of arthroplastic and osteosynthetic infections - Two cases with specific clinical presentation including formation of draining fistulae

This report describes two patients with orthopaedic implant infections, with specific clinical presentations including formation of draining fistulae. Propionibacterium acnes was isolated in multiple cultures in both cases. Phenotypic and genetic characterisation of the isolates clearly emphasizes the significance of P. acnes as an etiological agent of implant infections. These infections are insi

A method to determine the critical moisture level for unsaturated transport of ions

This study describes a method to obtain a certain humidity level by a certain drying treatment. This treatment was applied on cement based materials in order to identify the critical moisture level above which ion transport can occur. The drying is performed in two steps, first in one direction to reach a certain moisture level and then in the opposite direction to identify if ions can move at thi

A small-scale anatomical dosimetry model of the liver.

Radionuclide therapy is a growing and promising approach for treating and prolonging the lives of patients with cancer. For therapies where high activities are administered, the liver can become a dose-limiting organ; often with a complex, non-uniform activity distribution and resulting non-uniform absorbed-dose distribution. This paper therefore presents a small-scale dosimetry model for various

Signals and regulators that govern Streptomyces development

Streptomyces coelicolor is the genetically best characterized species of a populous genus belonging to the gram-positive Actinobacteria. Streptomycetes are filamentous soil organisms, well known for the production of a plethora of biologically active secondary metabolic compounds. The Streptomyces developmental life cycle is uniquely complex and involves coordinated multicellular development with

Baseline heterogeneity in glucose metabolism marks the risk for type 1 diabetes and complicates secondary prevention.

Non-diabetic children with multiple islet autoantibodies were recruited to a secondary prevention trial. The objective was to determine the predictive value of baseline (1) HbA1c and metabolic variables derived from intravenous (IvGTT) and oral glucose tolerance tests (OGTT), (2) insulin resistance and (3) number, type and levels of islet autoantibodies, for progression to type 1 diabetes.

Interrater variability of EEG interpretation in comatose cardiac arrest patients.

EEG is widely used to predict outcome in comatose cardiac arrest patients, but its value has been limited by lack of a uniform classification. We used the EEG terminology proposed by the American Clinical Neurophysiology Society (ACNS) to assess interrater variability in a cohort of cardiac arrest patients included in the Target Temperature Management trial. The main objective was to evaluate if m

Recruitment of Members from the Rare Biosphere of Marine Bacterioplankton Communities after an Environmental Disturbance

A bacterial community may be resistant to environmental disturbances if some of its species show metabolic flexibility and physiological tolerance to the changing conditions. Alternatively, disturbances can change the composition of the community and thereby potentially affect ecosystem processes. The impact of disturbance on the composition of bacterioplankton communities was examined in continuo

Seroconversion to islet autoantibodies between early pregnancy and delivery in non-diabetic mothers

Islet autoantibodies are currently used to classify type 1 diabetes at diagnosis as they reflect the autoimmune pathogenesis of the disease. The presence of maternal autoantibodies reactive with pancreatic islet antigens is thought to increase the risk for type 1 diabetes in the offspring. The objective of this study was to determine seroconversion to islet autoantibodies in non-diabetic mothers d

Small bowel obstruction: early parameters predicting the need for surgical intervention

To study and identify early clinical and radiological findings that could help to predict operative intervention for small bowel obstruction. One hundred and nine consecutive patients with small bowel obstruction who underwent small bowel follow-through examination with Gastrografin(A (R)) during 2005-2006. The patients were divided into an operative group and a non-operative group, n = 44 and 65,

PTEN and NEDD4 in Human Breast Carcinoma.

PTEN is an important tumor suppressor gene that antagonizes the oncogenic PI3K/AKT signaling pathway and has functions in the nucleus for maintaining genome integrity. Although PTEN inactivation by mutation is infrequent in breast cancer, transcript and protein levels are deficient in >25 % of cases. The E3 ubiquitin ligase NEDD4 (also known as NEDD4-1) has been reported to negatively regulate PTE

Liza Marklund och den feministiska litteraturfabriken. Om sanning, lögn och medielogik i Gömda-debatten

In her ”true” stories Buried Alive and Asylum Granted Liza Marklund, Swedish journalist and crime writer, acts as a ghost writer for Maria Eriksson’s presumed life story of abuse, hiding and flight to the USA where she, according to Marklund’s novel, was granted asylum. In 2008 the journalist Monica Antonsson published Mia – The Truth About Buried Alive. In the book she questions the factual backg

Genetically Distinct Subsets within ANCA-Associated Vasculitis

BACKGROUND Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis is a severe condition encompassing two major syndromes: granulomatosis with polyangiitis (formerly known as Wegener's granulomatosis) and microscopic polyangiitis. Its cause is unknown, and there is debate about whether it is a single disease entity and what role ANCA plays in its pathogenesis. We investigated its genetic
