Lateral gene transfer and gene duplication played a key role in the evolution of mastigamoeba balamuthi hydrogenosomes

Lateral gene transfer (LGT) is an important mechanism of evolution for protists adapting to oxygen-poor environments. Specifically, modifications of energy metabolism in anaerobic forms of mitochondria (e.g., hydrogenosomes) are likely to have been associated with gene transfer from prokaryotes. An interesting question is whether the products of transferred genes were directly targeted into the an

Acute phase markers in CSF reveal inflammatory changes in Alzheimer's disease that intersect with pathology, APOE ε4, sex and age

It is unknown how neuroinflammation may feature in the etiology of Alzheimer's disease (AD). We profiled acute phase response (APR) proteins (α1-antitrypsin, α1-antichymotrypsin, ceruloplasmin, complement C3, ferritin, α-fibrinogen, β-fibrinogen, γ-fibrinogen, haptoglobin, hemopexin) in CSF of 1291 subjects along the clinical and biomarker spectrum of AD to investigate the association between infl

Alterations of diffusion kurtosis and neurite density measures in deep grey matter and white matter in Parkinson's disease

In Parkinson's disease (PD), pathological microstructural changes occur and such changes might be detected using diffusion magnetic resonance imaging (dMRI). However, it is unclear whether dMRI improves PD diagnosis or helps differentiating between phenotypes, such as postural instability gait difficulty (PIGD) and tremor dominant (TD) PD. We included105 patients with PD and 44 healthy controls (H

Baring it all- undressing Cambrian ´Orsten´phosphatocopine arthropods using synchrotron X-ray tomographic microscopy

Synchrotron radiation X-ray tomographic microscopy (SRXTM) was used to virtually dissect and peel the shields off of the microscopic, bivalved phosphatocopine crustaceans in the Cambrian ‘Orsten’ type of preservation of Sweden. Doing so opened up for an array of concealed internal structures to be observed in a fully enclosed specimen of Hesslandona ventrospinata and a semi-enclosed specimen of He

Ostomy patients' perceptions of quality of care

AIM: This paper reports a study whose aim was to assess the quality of care in ostomy patients seen from a patient perspective.BACKGROUND: A stoma operation causes profound changes in a patient's life because of resulting physical damage, disfigurement, loss of bodily function, and change in personal hygiene. Such changes are a cause of major concern for patients and raise important issue for the

ON-Line alkali measurement for fuel quality control in biomass-Operated boilers

Today's power plants are shifting their combustion toward a more complex fuel mix on the grounds of environmental impact, cost, availability and regulations. Certain new types of fuel can be classified into the following groups: herbaceous material (straw and grass), agricultural by-products (pits, shells and hulls), wood, and waste fuels. These fuels contain various amounts of alkali metals, main

Sepsis Alert – a triage model that reduces time to antibiotics and length of hospital stay

Objective: To study if a modified triage system at an Emergency Department (ED) combined with educational efforts resulted in reduced time to antibiotics and decreased length of hospital stay (LOS) for patients with severe infection. Methods: A retrospective, observational study comparing patients before and after the start of a new triage model at the ED of a University Hospital. After the implem

Specialized photoreceptor composition in the raptor fovea

The retinae of many bird species contain a depression with high photoreceptor density known as the fovea. Many species of raptors have two foveae, a deep central fovea and a shallower temporal fovea. Birds have six types of photoreceptors: rods, active in dim light, double cones that are thought to mediate achromatic discrimination, and four types of single cones mediating color vision. To maximiz

Assessment of hygrothermal performance and mould growth risk in ventilated attics in respect to possible climate changes in Sweden

Most of the last 20 years in Sweden have been mild and wet compared to the 1961-1990 climate reference period. After a few relatively cold years in the mid-1980s, practically all years have been warmer than the preceding 30 years average. During the indicated period, an increase of moisture-related problems (mould growth) was observed in ventilated attics, a moisture sensitive building part.This w

Psychiatric diagnoses in older people with intellectual disability in comparison with the general population a register study

AIMS: To describe the occurrence of psychiatric diagnoses in a specialist care setting in older people with intellectual disability (ID) in relation to those found in the same age group in the general population.METHOD: A cohort of people with ID (n = 7936), aged 55 years or more in 2012, was identified, as was an age and sex-matched cohort from the general population (n = 7936). Information regar

Adaptive mitochondrial reprogramming and resistance to PI3K therapy

BACKGROUND: Small molecule inhibitors of phosphatidylinositol-3 kinase (PI3K) have been developed as molecular therapy for cancer, but their efficacy in the clinic is modest, hampered by resistance mechanisms.METHODS: We studied the effect of PI3K therapy in patient-derived tumor organotypic cultures (from five patient samples), three glioblastoma (GBM) tumor cell lines, and an intracranial model

Coeliac disease and invasive pneumococcal disease : a population-based cohort study

Severe infections are recognized complications of coeliac disease (CD). In the present study we aimed to examine whether individuals with CD are at increased risk of invasive pneumococcal disease (IPD). To do so, we performed a population-based cohort study including 29 012 individuals with biopsy-proven CD identified through biopsy reports from all pathology departments in Sweden. Each individual

The first 6 weeks of recovery after primary total hip arthroplasty with fast track : A diary study of 94 patients

Background and purpose — Fast-track protocols have been introduced worldwide to improve the recovery after total hip arthroplasty (THA). These protocols have reduced the length of hospital stay (LOS), and THA in an outpatient setting is also feasible. However, less is known regarding the first weeks after THA with fast track. We examined patients’ experiences of the first 6 weeks after hospital di

Use and definitions of perioperative mortality rates in low-income and middle-income countries : a systematic review

BACKGROUND: Aggregate and risk-stratified perioperative mortality rates (POMR) are well-documented in high-income countries where surgical databases are common. In many low-income and middle-income country (LMIC) settings, such data are unavailable, compromising efforts to understand and improve surgical outcomes. We undertook a systematic review to determine how POMR is used and defined in LMICs

The balance between under- and over-immunosuppression after heart transplantation with emphasis on acute cellular rejection and chronic kidney disease. Experiences from Skåne University Hospital in Lund 1988-2010

Background and aims:Heart transplantation (HT) constitutes the ultimate treatment choice for end-stage heart failure. Following HT, patients require life-long immunosuppressive treatment to prevent allograft rejection. Although survival has steadily increased over the last few decades, issues related to under- and over-immunosuppression remain common and continue to represent one of the most impor

Psychometric evaluation and refinement of the Prenatal Attachment Inventory

Objective: To explore the underlying structure of the Prenatal Attachment Inventory (PAI) and to assess the psychometric properties of the subscales. Background: The establishment of the mother-fetus relationship is an important developmental task for successful adaption to pregnancy, with implications for the well-being of mother and child. The PAI was developed to measure the relationship betwee

Perceived and measured indoor climate in new-family buildings including identifying technical deficiencies

When new buildings are constructed the indoor climate for the first period may differ from the one after some years due to various factors, for example may the emissions from the building materials be higher, possibly affecting the air quality, and the balancing of the technical systems; the mechanical supply and exhaust system and heating may not be completely finished. The perceived indoor clima

Inferring dispersal across a fragmented landscape using reconstructed families in the Glanville fritillary butterfly

Dispersal is important for determining both species ecological processes, such as population viability, and its evolutionary processes, like gene flow and local adaptation. Yet obtaining accurate estimates in the wild through direct observation can be challenging or even impossible, particularly over large spatial and temporal scales. Genotyping many individuals from wild populations can provide d

Regional differences in air velocity of microclimate inside clothing and bellows effect

Despite of a crucial role of microclimate inside clothing in thermal comfort, air velocity inside clothing has been hardly reported, ever since Lewis et al (1969) demonstrated that air velocity of the still air layer on the naked human body was 0.25 m/s using colour schlieren cinephotography. This study was aimed to investigate the air velocity of microenvironment inside clothing and the bellows e

Evolving geriatric anthropometrics- an interplay with lifestyle changes, birth cohort effects, and survival implications. : Results from the general population study, “Good Aging in Skåne,” Sweden.

There is a rising proportion of aging population worldwide. The high vulnerability of older adults to morbidity and mortality introduces an enormous health and economic burden to themselves and the society. The established leading cause of death among older adults is due to chronic and vascular diseases. These conditions are related to the nutritional status and are preventable with the help of ac
