Time-lapse imaging of Streptomyces hyphae revealed foci of the essential protein DivIVA at sites where lateral branches will emerge. Overexpression experiments showed that DivIVA foci can trigger establishment of new zones of cell wall assembly, suggesting a key role of DivIVA in directing peptidoglycan synthesis and cell shape in Streptomyces.

BACKGROUND: Current studies reveal a lack of consensus for the evaluation of physical and psychosocial problems after ICU stay and their changes over time. OBJECTIVES: The aim was to develop and evaluate the validity and reliability of a questionnaire for assessing physical and psychosocial problems over time for patients following ICU recovery. PATIENTS: Thirty-nine patients completed the questio

Background: Previous studies have indicated that transthyretin (TTR) levels in cerebrospinal fluid (CSF) are altered in depression and dementia. The present study aimed to investigate whether CSF TTR can be used to discriminate between patients with Alzheimer's disease (AD) and patients with dementia with Lewy bodies (DLB) with or without medication, as well as to reveal whether CSF TTR correlates

OBJECTIVE To determine whether hydrogen peroxide vapor (HPV) could be used to decontaminate caliciviruses from surfaces in a patient room. DESIGN Feline calicivirus (FCV) and murine norovirus (MNV) were used as surrogate viability markers to mimic the noncultivable human norovirus. Cell culture supernatants of FCV and MNV were dried in triplicate 35-mm wells of 6-well plastic plates. These plates

Radiative lifetimes for six highly excited levels in Fe II have been measured at Lund Laser Centre applying the laser induced fluorescence technique and two-step excitation. The energy levels belong to the even-parity 3d(6)(D-5)(4)d subconfiguration at about 10 eV. Branching fractions (BF:s) of 29 transitions from these levels to the 3d(6)(D-5)4p subconfiguration at about 5 eV have been measured i

No study has investigated the predictive validity and cut-off scores in diagnostic tests for falls used in in-home assessment in frail older people. The objective was to investigate the predictive validity for falls in the Downton Fall Risk Index (DFRI), Timed Up and Go (TUG) and Romberg test (RT) used in in-home assessment of frail older people (65+ years). Data on the diagnostic tests were colle

Abstract When studying the deposition of particles in wind tunnel experiments, we measure theairborne particles with an Aerodynamic Particle Sizer (APS). The deposited particles are examined with an optical microscope connected to an image analyzer. Calibration between the APS and the optical microscope determinations of particle size has been performed for particles of fused alumina. The particle

This nationwide study aimed to determine whether differences exist in age-specific and sex-specific familial risks for pulmonary embolism (PE), venous thrombosis of the lower limbs (VT) and other forms of venous thromboembolism (OVTE) among offspring, siblings and spouses of affected individuals. The Swedish Multi-Generation Register was linked to the Hospital Discharge Register data for the perio

Residual adsorptive activity of frits prepared by sintering silica gel particles used in capillary HPLC and electrochromatography can be significantly reduced by silanization. The adsorption of polar analytes on frits consisting of sintered normal-phase or reversed-phase silica gel before and after deactivation has been characterized by imaging with laser-induced fluorescence in combination with a

Inflammation and ischemia have a synergistic damaging effect in the immature brain. The role of tumor necrosis factor (TNF) receptors 1 and 2 in lipopolysaccharide (LPS)-induced sensitization and tolerance to oxygen-glucose deprivation (OGD) was evaluated in neonatal murine hippocampal organotypic slices. Hippocampal slices from balb/c, C57BL/6 TNFR1(-/-), TNFR2(-/-), and wild-type (WT) mice obtai

Anti-Ro(52/60) and anti-La constitute the hallmark autoantibodies in primary Sjögren's syndrome, being present in 40-70% of sera. Several anti-Ro/La assays exist, but antibody detection appears to be assay-specific, thus the aim of this study was to compare several anti-Ro/La assays. In total, 96 sera from individuals with primary Sjögren's syndrome and 114 healthy controls were tested for anti-Ro

Climate models provide the means of making projections of the future climate, under assumptions on alternative future land-use changes and greenhouse gas emissions. The basis for such climate projections is discussed in this chapter,´together with the presentation of overall climate scenario results of relevance for agriculture. The focus is on the period until 2050.

Using the concepts of social norms and social reality, this chapter explores why legal reforms that aimed to facilitate the formalization of informal workers have largely failed to influence vulnerable groups in developing countries. It explores the use of legal reforms in order to achieve development and poverty reduction. Using empirical material from a qualitative study conducted in Colombia am

OBJECTIVES: Most patients with pancreatic cancer who have undergone surgical resection eventually develop disease recurrence. ‍This study aimed to investigate whether there is evidence to support routine surveillance after pancreatic cancer surgery, with a secondary aim of analyzing the implementation of surveillance strategies in the Nordic countries.MATERIALS AND METHODS: A scoping review was co

OBJECTIVE: To develop a prediction model for major morbidity and endocrine dysfunction after CP which could help in tailoring the use of this procedure.SUMMARY BACKGROUND DATA: Central pancreatectomy (CP) is a parenchyma-sparing alternative to distal pancreatectomy for symptomatic benign and pre-malignant tumors in body and neck of the pancreas CP lowers the risk of new-onset diabetes and exocrine

To ensure that cities and urban ecosystems support human wellbeing and overall quality of life we need conceptual frameworks that can connect different scientific disciplines as well as research and practice. In this perspective, we explore the potential of a traits framework for understanding social-ecological patterns, dynamics, interactions, and tipping points in complex urban systems. To do so
