The autofluorescence spectroscopy of biologi- cal tissues is a powerful tool for non-invasive detection of tissue pathologies and evaluation of any biochemical and morphological changes arising during the lesions＇ growth. To obtain a full picture of the whole set of endogenous fluorophores appearing in the gastrointestinal （GI） tumors investigated, the technique of excitation-emission matrix （EEM） development was applied in a broad spectral region, covering the ultraviolet and visible spectral ranges. We could thus address a set of diagnostically-important chromophores and their alterations during tumor develop- ment, namely, collagen, elastin, nicotinamide adenine dinucleotide （nADH）, flavins, porphyrins, while hemo- globin＇s absorption influence on the spectra obtained could be evaluated as well. Comparisons are presented between EEM data of normal mucosae, benign polyps and malignant carcinoma, and the origins are determined of the fluorescence signals forming these matrices.

The statement of Theorem 1 of the paper "On a Theorem of Leray" in Vol.X, no. 7, 1961, of this iournal should be corrected to take the following form: Theorem 1. Let H be a cohomology theory defined on pairs of normal spaces which possess the strong excision property. Let E be a bicompact Hausdorff space with a finite closed covering F such that each non-empty intersection of sets in F has the same cohomology groups in dimensions up to r as those of a point, then the cohomology group in dimension r of E will be isomnorphic to that of the nerve complex K of the covering F, etc.

Organophosphorus pesticides (OPPs) in foods pose a serious threat to human health， motivating the development of novel analytical methods for their rapid detection and quantification. A magnetic covalent organic framework (M-COF) adsorbent for the magnetic solid-phase extraction (MSPE) of OPPs from foods was reported. M-COF was synthesized by the Schiff base condensation reaction of 1，3，5-tris (4-aminophenyl)benzene and 4，4-biphenyldicarboxaldehyde on the surface of amino-functionalized magnetic nanoparticles. Density–functional theory (DFT) calculations showed that adsorption of OPPs onto the surface of M-COF involved hydrophobic effects， Van der Waals interactions， π–π interactions， halogen-n bonding， and hydrogen bonding. Combined with gas chromatography–mass spectrometry (GC–MS) technology， the MSPE method features low limits of detection for OPPs (0.002–0.015 μg/L)， good reproducibility (1.45%–6.14%)， wide linear detection range (0.01–1 μg/L， R≥ 0.9935)， and satisfactory recoveries (87.3%–110.4%). The method was successfully applied for the trace analysis of OPPs in spiked fruit juices.
