A weak (< 1000 G) magnetic field can influence photochemical processes through its effect on electron spin dynamics in a photogenerated radical pair. In a solution of pyrene and dimethylaniline this effect manifests as magnetic field-dependent exciplex fluorescence. Here we describe magnetofluorescence imaging (MFI). A localized magnetic null defines a fluorescence detection volume, which is sc...

This paper examines whether the loan strategy of a microfinance institution (MFI) is shaped by entry bank. Specifically, we investigate distance between borrower an MFI and closest bank influences conditions provided MFI. We use original panel data set 32,374 loans granted to 14,834 borrowers one largest MFIs in Madagascar 2008 2014. find that closer located given borrower, larger obtained less...

polycrystalline mfi zeolite membranes were prepared on α-alumina tubular support by hydrothermal treatments at 413 k. the synthesized zeolite membranes were characterized by xrd, sem and single gas permeation. the influence of hydrothermal treatment steps and the calcination time on the zeolite layer formation were investigated. mfi zeolite membrane prepared by four subsequent hydrothermal trea...

Ultrathin MFI-zeolite nanosheets can be packed on porous supports to create molecular sieve membranes. The nanosheets on porous support reduce morphological damage seen in regular MFIzeolite crystals [1]. MFI-zeolite belongs to pentasil family of zeolites where the periodic building unit (PerBU) is composed of 12 interconnected SiO4 tetrahedral (T12) units of 41m2 (D2d) symmetry [2]. Rotation o...

A compact and highly b-oriented MFI monolayer was fabricated with a novel phase-segregation-induced selfassembly method. When MFI microcrystals were dispersed uniformly in an appropriate dispersant (sec-butanol) containing a trace amount of binding agent (linoleic acid), these microbuilding blocks were spontaneously self-assembled into a compact monolayer at an air-liquid interface. In particul...

Previous studies suggested that both the frequency and the mean fluorescence intensity (MFI) of cytokine secreting T cells could be of great value for immunogenicity evaluation of a vaccine. In this study, by constructing epitope-based DNA vaccines encoding a previously identified CD8(+) T cell epitope, we investigated the influence of multiplying epitope copies on both the frequency and the MF...

BACKGROUND Fatigue often occurs as long-term complication in chronically critically ill (CCI) patients after prolonged intensive care treatment. The Multidimensional Fatigue Inventory (MFI-20) has been established as valid instrument to measure fatigue in a wide range of medical illnesses. Regarding the measurement of fatigue in CCI patients, the psychometric properties of the MFI-20 have not b...

OBJECTIVES The purpose of this study was to monitor the effects of chimeric 7E3 Fab (ReoPro) on leukocyte and platelet activation and interaction during coronary angioplasty. BACKGROUND Increased expression of CD11b on monocytes and neutrophils promotes their adhesion to endothelial cells, extracellular matrix and smooth muscle cells. Thrombin-activated platelets adhere via P-selectin to mono...

Purpose: To compare the postoperative course of elderly patients (≥70 years) submitted to minimally-invasive(MIDP) vs. open distal pancreatectomy(ODP), and evaluate if modified Frailty Index (mFI) predicts surgical course. Methods: Data 204 aged ≥70 who underwent DP at single institution between March 2011 December 2019 were retrospectively retrieved. Of these patients, 42 MIDP propensity-score...

MFI type zeolite membranes were synthesized on two types of supporting materials, alumina (α-alumina) and yttria-stabilized zirconia (YSZ) coated alumina. Membranes were prepared by template-free secondary growth method with multiple growth steps in order to minimize intercrystalline gaps. Gas permeation characteristics, thermal and hydrothermal stability for MFI type zeolite membranes were exa...
