PURPOSE To investigate the characteristics of visual field (VF) progression in medically treated normal-tension glaucoma (NTG) patients (Koreans) with unstable ocular perfusion pressure (OPP). METHODS One hundred one eyes of 101 NTG patients followed up for more than 4 years (mean follow-up, 6.2 years ± 12.1 months) were included. Modified Anderson criteria (MC) and linear regression analysis...

CONTEXT Iodine is critical for normal thyroid hormone synthesis and brain development during infancy, and preterm infants are particularly vulnerable to the effects of both iodine deficiency and excess. Use of iodine-containing skin antiseptics in intensive care nurseries has declined substantially in recent years, but whether the current dietary iodine intake meets the requirement for hospital...

The accumulation of calcium, magnesium and phosphorus was measured during an 8-week period in the early life stages of the air-breathing armoured catfish Megalechis personata acclimated to low-mineral fresh water (0.073 mmol l-1 calcium, 0.015 mmol l-1 magnesium, <0.001 mmol l-1 phosphate) and high-mineral fresh water (0.59 mmol l-1 calcium, 1.94 mmol l-1 magnesium, <0.001 mmol l-1 phosphate). ...

some physicochemical parameters of honey have been introduced by the international honey commission to evaluate its quality and origin but processes such as heating and filtering can affect these parameters. in traditional iranian medicine, deslagging process involves boiling honey in an equal volume of water and removing the slag formed during process. the aim of this study was to determine th...

Terephthalic acid (PTA), a monomer in the synthesis of polyethylene terephthalate (PET), is obtained by the oxidation of petroleum-derived p-xylene. There is significant interest in the synthesis of renewable, biomass-derived PTA. Here, routes to PTA starting from oxidized products of 5-hydroxymethylfurfural (HMF) that can be produced from biomass are reported. These routes involve Diels-Alder ...

[1] The cosmic ray record for the interval 1428–2005 has been inverted using the method of Caballero-Lopez et al. (2004) to estimate the annual averages of the heliomagnetic field (HMF) near Earth. There is good agreement with the results obtained by others using two independent methodologies based upon the sunspot and geomagnetic records. This provides confidence in the overall validity of all...

Background and objectives: Cancer-related fatigue (CRF) is the most common and distressing symptom that affects overall quality of life of cancer patients. Due to the multi-factorial etiology, there is currently no “gold standard” for treatment of CRF. Considering the growing importance of national traditional medicines, natural remedies are viewed as playing distinctive role. ...

A lo largo de mi doctorado, me dedicaré a desarrollar catalizadores nanoestructurados basados en materiales mesoporosos, modificados con nanopartículas activas, para su aplicación la obtención 5-hidroximetil furfural (HMF) partir hidratos carbonos simples (hexosas); y posterior hidrogenación del HMF 2,5-dimetil furano (DMF) producto alto valor energético.

5-hydroxymethylfurfural (HMF) is an aromatic compound that admitted indicator of reduced quality in different foodstuffs. Here, a novel, sensitive, and simple online solid-phase extraction (SPE) based on molecularly imprinted sol-gel polymer (MIS) coupled to HPLC-UV was designed developed for the determination HMF. Under optimum conditions, good linearity achieved from 0.03 0.45 μg ml-1 with re...
