Rearrangements of Cycloalkenyl Aryl Ethers
Molecules, 2016 Rearrangement reactions of cycloalkenyl phenol and naphthyl ethers and the acid-catalyzed cyclization of the resulting product were investigated. Claisen rearrangement afforded 2-substituted phenol and naphthol derivatives.

Identification and quantification of carbamate pesticides in dried lime tree flowers by means of excitation-emission molecular fluorescence and parallel factor analysis when quenching effect exists [PDF]
, 2014 A non-separative, fast and inexpensive spectrofluorimetric method based on the second order calibration of excitation-emission fluorescence matrices (EEMs) was proposed for the determination of carbaryl, carbendazim and 1-naphthol in dried lime tree ...

Coloration Technology, EarlyView.Abstract Plants and their extracts have been used for dyeing fabrics, skin and hair for thousands of years and have been experiencing a revival in the last years due to increasing health risks arising from oxidative hair dye precursors. We developed a novel two‐step method to dye keratin fibres based on in situ formed silver nanoparticles including a ...

A micromethod for the determination of arginine [PDF]
, 1941 Micromethods for the determination of arginine based on the use of the Sakaguchi reagent have been described (14). This reagent gives a strong color with glycocyamine, arginine, and other monosubstituted guanidine derivatives.

Journal of Fish Diseases, EarlyView.ABSTRACT This study presents the first description and characterisation of Lactococcus garvieae isolated from diseased European sea bass (Dicentrarchus labrax) farmed in Spain. During autumn 2023, two fish farms were affected by infectious outbreaks causing moderate cumulative fish mortality (5%–10%). Diseased fish showed clinical signs of haemorrhagic

Chiral separation by SMB chromatography [PDF]
, 2000 The paper deals with chiral separation by simulated moving bed (SMB) chromatography. A model for the prediction of the cyclic steady-state performance of the SMB, based on the analogy with the true moving bed (TMB), is developed assuming multicomponent ...

Mapping the murine TMJ glenoid fossa over development, homeostasis and in response to disease
Journal of Anatomy, EarlyView.The fibrocartilage of the murine glenoid fossa and condyle of the temporomandibular joint are shown to form at distinct times with distinct molecular identities. Changes in the condyle during disease lead to remodelling of the fossa to maintain joint alignment.
