Åldrandet hos oss människor är individuellt och sker gradvis under en lång tid. Vissa funktioner i kroppen försämras och äldre människor har ofta av olika anledningar svårigheter att få i sig den mängd näring som de har ett behov utav, därför behöver de oftast dela upp sin kost i fler måltider fördelat under dagen. I denna uppsats jämförs kosten som serveras i ett ålderdomshem i en mindre kommun iThe aging of us humans is individual and occurs gradually over a long period of time. Some functions in the body deteriorate and older people often have difficulty for various reasons to get the amount of nutrition they need, so they usually need to divide their diet into more meals distributed during the day. In this essay, the diet served in a retirement home in a small municipality in northwest

Formation of the hematopoietic stem cell (HSC) niche in bone marrow (BM) is tightly associated with endochondral ossification, but little is known about the mechanisms involved. We used the oc/oc mouse, a mouse model with impaired endochondral ossification caused by a loss of osteoclast (OCL) activity, to investigate the role of osteoblasts (OBLs) and OCLs in the HSC niche formation. The absence o

Identification and isolation of cardiomyocytes from the heart, embryonic stem cells, or induced pluripotent stem cells is a challenging task and will require specific isolation techniques. Less than 30% of the cells within the murine heart are cardiomyocytes and, what is more, there are multiple sub-populations of cardiomyocytes like atrial, ventricular and conduction system cardiomyocytes. In Pap

Background. Antimicrobial stewardship programs are increasingly implemented in hospital care. They aim to simultaneously optimize outcomes for individual patients with infections and reduce financial and health-associated costs of overuse of antibiotics. Few studies have examined the effects of antimicrobial stewardship programs in settings with low proportions of antimicrobial resistance, such as

Nanoscale contacts between metals and semiconductors are critical for further downscaling of electronic and optoelectronic devices. However, realizing nanocontacts poses significant challenges since conventional approaches to achieve ohmic contacts through Schottky barrier suppression are often inadequate. Here we report the realization and characterization of low n-type Schottky barriers (~0.35 e

To identify new risk variants for chronic lymphocytic leukemia (CLL), we conducted a genome-wide association study of 299,983 tagging SNPs, with validation in four additional series totaling 2,503 cases and 5,789 controls. We identified four new risk loci for CLL at 2q37.3 (rs757978, FARP2; odds ratio (OR) = 1.39; P = 2.11 x 10(-9)), 8q24.21 (rs2456449; OR = 1.26; P = 7.84 x 10(-10)), 15q21.3 (rs7

Background: To study costs and outcome for serious hand and arm injuries during the first year after the trauma. Methods: In patients with a Hand Injury Severity Score (HISS) > 50, DASH and EQ-5D scores as well as factors related to costs within the health care sector, costs due to lost production and total costs were evaluated. Coxregression analysis stratifying for mechanism of injury was used t

We present a study of InAs/InSb heterostructured nanowires by X-ray photoemission spectroscopy (XPS), scanning tunneling microscopy (STM), and in-vacuum electrical measurements. Starting with pristine nanowires covered only by the native oxide formed through exposure to ambient air, we investigate the effect of atomic hydrogen cleaning on the surface chemistry and electrical performance. We find t

Hematopoiesis is a tightly regulated process in which hematopoietic stem cells reside at the apex of the hierarchy, and produce all kinds of mature blood cells by differentiation to replenish the cell loss in homeostasis and acute injury. In past few decades, much effort has been made to purify hematopoietic stem cells (HSCs) and lineagecommitted progenitor cells both in mouse and human, enabling

Desertification, climate variability and food security are closely linked through drought, land cover changes, and climate and biological feedbacks. In Ghana, only few studies have documented these linkages. To establish this link the study provides historical and predicted climatic changes for two drought sensitive agro-ecological zones in Ghana and further determines how these changes have influ

Here we present unequivocal experimental proof that microscale cofactor- and membrane-less, direct electron transfer based enzymatic fuel cells do produce significant amounts of electrical energy in human lachrymal liquid (tears). 100μm diameter gold wires, covered with 17nm gold nanoparticles, were used to fashion three-dimensional nanostructured microelectrodes, which were biomodified with Coryn

BACKGROUND:: The use of league tables during the last decade has frequently been employed to assess quality in health care. However, few studies have attempted to assess quality by quantifying the variability across the organizational units or attempted to investigate whether the units are the correct context that really influences the outcome under study. OBJECTIVES:: To quantify the variation be

Motivated by growing considerations of the scale, severity, and risks associated with human exposure to indoor particulate matter, this work reviewed existing literature to: (i) identify state-of-the-art experimental techniques used for personal exposure assessment; (ii) compare exposure levels reported for domestic/school settings in different countries (excluding exposure to environmental tobacc

Increased red cell distribution width (RDW) has been related to poor prognosis in patients with cardiovascular disease, and is a predictor of cardiovascular mortality in the general population. The purpose of the present study was to investigate if RDW is associated with increased incidence of stroke and its subtypes in individuals from the general population.

Metal nanostructures can transfer electromagnetic energy from femtosecond laser pulses to the near-field down to spatial scales well below the optical diffraction limit. By combining few-femtosecond laser pulses with photoemission electron microscopy, we study the dynamics of the induced few-cycle near-field in individual bowtie nanoantennas. We investigate how the dynamics depend on antenna size

Cadmium is a non-essential toxic metal with multiple adverse health effects. Cadmium has been shown to be associated with cardiovascular diseases, but few studies have investigated heart failure (HF) and none of them reported atrial fibrillation (AF). We examined whether cadmium exposure is associated with incidence of HF or AF.
