Involvement of adenomatous polyposis coli (APC)/beta-catenin signalling in human breast cancer

We studied the relevance of adenomatous polyposis coli (APC)/beta-catenin signalling in the development of breast cancer by analysing the expression of beta-catenin in 54 primary breast tumours (34 ductal and 20 lobular). We showed that 13% of the tumours exhibited upregulated levels of beta-catenin in the cytosol suggesting that defects in APC/beta-catenin signalling components had lowered the ra

Exposure to bisphenol A, but not phthalates, increases spontaneous diabetes type 1 development in NOD mice

Type 1 diabetes mellitus (T1DM) is an autoimmune destruction of insulin producing pancreatic beta-cells due to a genetic predisposition and can be triggered by environmental factors. We have previously shown that bisphenol A (BPA) accelerates the spontaneous development of diabetes in non-obese diabetic (NOD) mice. Here, we hypothesized that oral exposure to a mixture of the endocrine disruptors B

Maxwell-compensated design of asymmetric gradient waveforms for tensor-valued diffusion encoding.

PURPOSE:Diffusion encoding with asymmetric gradient waveforms is appealing because the asymmetry provides superior efficiency. However, concomitant gradients may cause a residual gradient moment at the end of the waveform, which can cause significant signal error and image artifacts. The purpose of this study was to develop an asymmetric waveform designs for tensor-valued diffusion encoding that i

Data replication matters to an underpowered study, but replicated hypothesis corroboration counts

Before replication becomes mainstream, the potential for generating theoretical knowledge better be clear. Replicating statistically significant nonrandom data shows that an original study made a discovery; replicating a specified theoretical effect shows that an original study corroborated a theory. Yet only in the latter case is replication a necessary, sound, and worthwhile strategy.

Association of vitamin K dependent coagulation proteins and C4b binding proteins with triglyceride rich proteins of human plasma

The triglyceride (TG) concentration in plasma is an independent risk factor for coronary heart disease. There is evidence that TG-rich lipoprotein (TGRLP), ie, chylomicrons (CMs), chylomicron remnants (CMRs), and VLDLs associate with factor VII and prothrombin and that the association enhances a platelet factor Xa-mediated prothrombin activation when the CM-prothrombin complex is exposed to platel

Växtskydd i raps, åkerbönor och ärter : Kunskapsbehov och forskningsinriktningar

Denna rapport är framtagen på initiativ av en fokusgrupp för växtskydd i avbrottsgrödor som bildats inom Plattform växtskydd vid SLU. Rapportens syfte är att identifiera betydande kunskapsluckor som behöver fyllas om ett effektivt och hållbart växtskydd ska kunna uppnås i raps, åkerbönor och ärter, som är de arealmässigt viktigaste avbrottsgrödorna till spannmål i Sverige. I sammanställningen besk

Catabolism of prothrombin-chylomicron complexes in vivo in the rat

The metabolism in vivo in the rat of 125I-prothrombin-chylomicron complexes was compared to that of free 125I-prothrombin injected in saline or together with chyle chylomicrons. The group that obtained 125I-prothrombin-chylomicron complexes exhibited a faster initial decrease of plasma 125I-prothrombin, a higher radioactivity in the liver and more trichloroacetic acid soluble 125I in plasma than i

Binding of prothrombin to chyle chylomicrons: effects of temperatuure and calcium ions, and role of surface phospholipids.

The ability of chyle chylomicrons to bind prothrombin has been studied. Rat chyle chylomicrons were incubated with human 125I-prothrombin and binding was examined by separating the chylomicrons from free 125-I-prothrombin by density-gradient ultracentrifugation, and by gel filtration on Sepharose CL-2B. A significant binding of prothrombin to chyle chylomicrons occurred. The complex formation was

Role of platelet factor Xa in chylomicron-prothrombin complexes induced platelet activation

The effects of chylomicron-prothrombin complexes on platelet activation, including platelet aggregation, serotonin release, arachidonic acid release and increases of platelet cytosolic [Ca2+]i were examined. Furthermore the role of platelet factor Xa on the conversion of chylomicron bound prothrombin to thrombin was studied by using a synthetic inhibitor of factor Xa, TenStop. The chylomicron-protThe effects of chylomicron-prothrombin complexes on platelet activation, including platelet aggregation, serotonin release, arachidonic acid release and increases of platelet cytosolic [Ca2+]i were examined.

Chylomicron induced prothrombin activation and platelet aggregation

The effects on platelet aggregation of native rat chyle chylomicrons, chylomicron remnants, and chylomicrons that had been preincubated with rat or human EDTA-plasma, serum, whole blood, or pure human prothrombin were examined. The native chyle chylomicrons did not induce platelet aggregation but decreased ADP- and thrombin-induced platelet aggregation and [14C]serotonin release. Chylomicron remna

Minimum quantity lubrication (MQL) with carbon nanostructured additives in sheet metal forming

This work is an experimental study covering minimum quantity lubrication (MQL) in sheet metal forming. Two different lubricants have been studied. Nanosized graphite platelets (GnP) has been tested as additives to the base oils in order to improve the lubricant performance. The experiments have been performed utilizing a laboratory tribotester based on strip drawing. Friction measurements have bee

Influence of GnP additive to vegetable oil on machining performance when MQL-assisted turning Alloy 718

The current study demonstrates through experiment the effect of solid lubricant assisted minimum quantity lubrication (MQL) on the machining performance when turning Alloy 718 with cemented carbide tools. A powder of nanosized (~30 nm) graphite nanoplatelets (GnP) was dispersed (0.2% vol.) in a vegetable oil-based lubricant “ECOLUBRIC E200L” and used in MQL-assisted machining. The effect of cuttin
