Characterization of the biochemical and biophysical properties of the Saccharomyces cerevisiae phosphate transporter Pho89

In Saccharomyces cerevisiae, Pho89 mediates a cation-dependent transport of Pi across the plasma membrane. This integral membrane protein belongs to the Inorganic Phosphate Transporter (PiT) family, a group that includes the mammalian Na(+)/Pi cotransporters Pit1 and Pit2. Here we report that the Pichia pastoris expressed recombinant Pho89 was purified in the presence of Foscholine-12 and function

Gold- and silver nanoparticles affect the growth characteristics of human embryonic neural precursor cells.

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

Repeated Radioimmunotherapy with (177)Lu-DOTA-BR96 in a Syngeneic Rat Colon Carcinoma Model.

Abstract Aim: Fractionation is generally used as a mean to improve radioimmunotherapy (RIT). Since RIT is considered suitable for small-volume disease, the aim of the current study was to investigate whether repeated administration of (177)Lu-labeled mAb BR96 was tolerated and could delay or prevent metastatic disease after complete remission of the tumor obtained by the first administration. Meth

Lead, mercury, and cadmium in blood and their relation to diet among Swedish adults

The aim of the present study was to examine the body burden of lead (Pb), mercury (Hg), and cadmium (Cd) in blood among Swedish adults and the association between blood levels, diet and other lifestyle factors. The study was based on a subgroup (n = 273) of the national survey Riksmaten 2010-2011 (4-day food records and questionnaire). Lead, Hg, and Cd were measured in whole blood, and Cd addition

Gastroparesis is associated with oxytocin deficiency, oesophageal dysmotility with hyperCCKemia, and autonomic neuropathy with hypergastrinemia

Background: Gastrointestinal (GI) dysmotility and autonomic neuropathy are common problems among diabetics with largely unknown aetiology. Many peptides are involved in the autonomic nervous system regulating the GI tract. The aim of this study was to examine if concentrations of oxytocin, cholecystokinin (CCK), gastrin and vasopressin in plasma differ between diabetics with normal function and dy

Batch Quantities when Forecasts are Improving

This paper considers the choice of initial batch quantities when demand forecasts are improving. We assume that the standard deviation of the demand per period is decreasing exponentially and approaching a long-run value. A discrete time stochastic single-level inventory model is considered. There are traditional holding and backorder costs as well as an ordering cost. The ordering periods must be

Live or Let Die? Alternative Routes to Industry Exit

Each year around 8% of Swedish manufacturing firms leave an industry. Of the exit routes available, the least likely is firm closure. Firms are more likely to merge, become acquired or switch to a new industry. We investigate the importance of a range of firm and industry characteristics for the exit decision of Swedish firms from 1980–1996. From our analysis two patterns are evident. First, firms

Evaluation of the prognostic significance of MSMB and CRISP3 in prostate cancer using automated image analysis.

Despite prostate cancer being the most frequent cancer in men in the Western world, tissue biomarkers for predicting disease recurrence after surgery have not been incorporated into clinical practice. Our group has previously identified β-microseminoprotein (MSMB) and cysteine-rich secretory protein-3 (CRISP3) as independent predictors of biochemical recurrence after radical prostatectomy. The pur

Radical Online Video : YouTube, video activism and social movement media practices

This thesis explores contemporary modes of video activism for a radical politics of the Left. It offers an analytical contribution to media and communication that promotes an understanding of radical online video as modes of political engagement in contemporary online environments. By focusing on YouTube as one of the most prevalent spaces in which radical video is screened and experienced today,

A Monte Carlo Study of the Necessary and Sufficienct Conditions for Weak Separability

Weak separability is an important concept in many fields of economic theory. This chapter uses Monte Carlo experiments to investigate the performance of newly developed nonparametric revealed preference tests for weak separability. A main finding is that the bias of the sequentially implemented test for weak separability proposed by Fleissig and Whitney (2003) is low. The theoretically unbiased Sw

Vertical InAs nanowire wrap gate transistors with f(t) > 7 GHz and f(max) > 20 GHz.

In this letter we report on high-frequency measurements on vertically standing III-V nanowire wrap-gate MOSFETs (metal-oxide-semiconductor field-effect transistors). The nanowire transistors are fabricated from InAs nanowires that are epitaxially grown on a semi-insulating InP substrate. All three terminals of the MOSFETs are defined by wrap around contacts. This makes it possible to perform high-

Tuning the spin state of iron phthalocyanine by ligand adsorption

The future use of single-molecule magnets in applications will require the ability to control and manipulate the spin state and magnetization of the magnets by external means. There are different approaches to this control, one being the modification of the magnets by adsorption of small ligand molecules. In this paper we use iron phthalocyanine supported by an Au(111) surface as a model compound

No title

The emphasis on the equal and eternal responsibility of subjects of different gender and social positions in M.F. Roos's dialogue books promoted a special combination of radical equality in anthropology and a conservative understanding of society. A Pietist teaching on salvation permeates the Orthodox principles on vocation in such a way, that the vocation to community life as a Christian farmer,

Goniometer Crosstalk Compensation for Knee Joint Applications

Electrogoniometers are prone to crosstalk errors related to endblocks rotation (general crosstalk) and to the characteristics of each sensor (individual crosstalk). The aim of this study was to assess the crosstalk errors due to endblock misalignments and to propose a procedure to compensate for these errors in knee applications. A precision jig was used to simulate pure +/- 100 degrees flexion/ex

Genetic screening in sudden cardiac death in the young can save future lives

Autopsy of sudden cardiac death (SCD) in the young shows a structurally and histologically normal heart in about one third of cases. Sudden death in these cases is believed to be attributed in a high percentage to inherited arrhythmogenic diseases. The purpose of this study was to investigate the value of performing post-mortem genetic analysis for autopsy-negative sudden unexplained death (SUD) i

Male Subfertility and Prostate Cancer Risk: Epidemiological and Genetic Studies

Popular Abstract in Swedish De manliga könshormonerna, sk. androgener, spelar en nyckelroll under foster-utvecklingen av de manliga inre (t ex. blåshalskörtel/prostata) och yttre (t ex. penis) könsorganen. Androgenerna stimulerar även tillväxten av desamma under puberteten samt upprätthåller de manliga kroppsegenskaperna under vuxenlivet. De två huvudsakliga androgenerna är testosteron (T) samt 5αAndrogen action plays a pivotal role in male reproductive tract physiology and pathology. The androgen receptor (AR) gene harbors two codon repeat tracts: the CAG and GGN repeats, encoding corresponding amino acid sequences of variable length; the polyglutamine and polyglycine stretches, respectively. Variation in CAG repeat length had been associated with a number of andrological disorders, where
