Deactivation of frits for use in capillary high-performance liquid chromatography and capillary electrochromatography with characterization by imaging with laser-induced fluorescence

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

Location of metastases in cancer of unknown primary are not random and signal familial clustering.

Cancer of unknown primary (CUP) is a fatal disease diagnosed through metastases. It shows intriguing familial clustering with certain defined primary cancers. Here we examine whether metastatic location in CUP patients is related to primary non-CUP cancers in relatives based on the Swedish Cancer Registry. Standardized incidence ratios (SIRs) were calculated for CUP patients defined by metastatic

A 4.6GHz PLL with automatic frequency calibration based on multiple-pass ring oscillator

A good-performance high-frequency Phase Locked Loop using a ring oscillator is described. A Voltag e Controlled Oscillator with automatic calibration of frequency fluctuated by proce ss and tempe rature variations is propo sed. The VCO adopts new multiple-pass loop to improve frequency with unchangeable stages (phases). The circuit is implemented with TSMC O. I8um standard CMOS technology and powe

Tracking travel and tourism: Towards sustainability reporting for tour operators

Tourism is today the biggest industry in the world, and tour operators are a central link in the tourism supply chain. As a consequence of their key position, tour operators have the potential to influence both the primary producers of tourist services and the tourists. Increased awareness of the media and general public will create pressures on the tour operators - first to work towards incorpora

Inhibition of MEK5 by BIX02188 induces apoptosis in cells expressing the oncogenic mutant FLT3-ITD.

Fms-like tyrosine kinase-3 (FLT3) is a growth factor receptor normally expressed on hematopoietic progenitor cells. Approximately one third of all patients with AML carry an activating mutation in FLT3 that drives proliferation and survival of the leukemic cells. The most common activating mutation is the so-called internal tandem duplication (ITD), which involves an in-frame duplication of a segm

Independent measures of insulin secretion and insulin sensitivity during the same test: the glucagon-insulin tolerance test.

Background. To validate a test for independent assessment of insulin secretion and insulin sensitivity during the same occasion for metabolic studies in clinical practice, i.e. combined glucagon-stimulated C-peptide test and insulin tolerance test (GITT). Subjects and methods. We measured C-peptide response to 0.5 mg of intravenous glucagon followed 30 min later by administration of 0.05 U kg(-1)

Water, well-being and social complexity in insula V1 : A Pompeian city block revisited

Swedish archaeologists have been working in Pompeii since 2000. Our fieldwork has consisted mainly of the study of standing walls and cleared floor levels in a city block unearthed in the 19th century and of the production of a comprehensive documentation, presented in an open access publication: www.pompejiprojektet.se/insula.php. The perspective of the present paper is the insula as a whole. Its
