The heterogeneous reactions of SO2 and NH3 on typical mineral oxides were investigated using in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). A new sulfate formation pathway was proposed where NH3 accelerated the formation of sulfate species. The results revealed that surface hydroxyls and oxygen played principal roles in the conversion of SO2 to sulfate. It was pro...

This case concerns a 17-year-old boy, who was given the diagnosis of Alpers syndrome only postmortem when a homozygous 1399G-->A (A467T) mutation was found in the linker-region of POLG1. Serial muscle and liver biopsies as well as brain MRI scans in our patient ranging from early childhood to postmortem analyses showed that (i) routine diagnostic procedures can be normal in the early stage of t...

Diffuse optical imaging is a medical imaging technique that is beginning to move from the laboratory to the hospital. It is a natural extension of near-infrared spectroscopy (NIRS), which is now used in certain niche applications clinically and particularly for physiological and psychological research. Optical imaging uses sophisticated image reconstruction techniques to generate images from mu...

Diffuse optical imaging can measure brain activity noninvasively in humans through the scalp and skull by measuring the light intensity modulation arising from localized-activity-induced absorption changes within the cortex. Spatial resolution and localization accuracy are currently limited by measurement geometry to approximately 3 cm in the plane parallel to the scalp. Depth resolution is a m...

For a complete 12 μm flux-limited sample of 207 IRAS sources (F12 ≥ 150 Jy, |b| ≥ 5), the majority of which are AGB stars (∼87%), we have extracted light curves in seven infrared bands between 1.25 μm − 60 μm using the database of the Diffuse Infrared Background Experiment (DIRBE) instrument on the Cosmic Background Explorer (COBE) satellite. Using previous infrared surveys, we filtered these l...

Metachromatic leucodystrophy is deserving an increasing interest from neurologists and pediatricians, mainly because it is the only disease in the whole group of diffuse cerebral sclerosis amenable to an intra vitam diagnosis by means of bloodless procedures. The merit for this belongs to Austin 1 , who introduced a simple test to demonstrate metachromatic bodies in the urine sediment. Although...

Greenhouse and field experiments showed that conidia of the fungal pathogen, Phoma commelinicola, exhibited bioherbicidal activity against spreading dayflower (Commelina diffusa) seedlings when applied at concentrations of 10 to 10 conidia·mL. Greenhouse tests determined an optimal temperature for conidial germination of 25 °C–30 °C, and that sporulation occurred on several solid growth media. ...

Sir, We read with interest the study of Coras et al. (2014) reporting the absence of verbal anterograde episodic memory (AEM) impairment in patients with mesial temporal lobe epilepsy (MTLE) with a hippocampal sclerosis ILAE type 2 classification (HS ILAE 2, i.e. CA1 predominant cell loss). This finding may provide an anatomical basis for the dissociation of anterograde/long-term episodic memor...

An efficient computation of the time-dependent forward solution for photon transport in a head model is a key capability for performing accurate inversion for functional diffuse optical imaging of the brain. The diffusion approximation to photon transport is much faster to simulate than the physically correct radiative transport equation (RTE); however, it is commonly assumed that scattering le...

background: saffron (crocus satious l.) provides a variety of promising preventive and therapeutic effects with non-considerable side effects. objective: based on our knowledge, this is the first study that simultaneously has reviewed the effect of saffron extract and its constituents on the factors associated with neuropsychological, cardiovascular, and gastrointestinal tract diseases. methods...
