Abstract

По атомно-эмиссионным спектрам, возбуждаемым в воздушно-ацетиленовом пламени и регистрируемым в диапазоне 390-860 нм, на Новосибирском заводе химконцентратов проводят определение 0.1-100 мг/л щелочных металлов и кальция. При их одновременном измерении в широком интервале концентраций время накопления аналитического сигнала определяется минимальной концентрацией кальция в пробе. Однако, при увеличении длительности регистрации сигнала, интенсивность высокочувствительных линий натрия и калия уходит в насыщение, что не позволяет обеспечить возможность их определения во всем необходимом диапазоне концентраций. Другие аналитические линии калия и натрия в указанной выше рабочей спектральной области обладают на 3-4 порядка меньшей чувствительностью. В результате этого возникает разрыв в диапазоне определяемых концентраций. В работе приводится способ устранения данного разрыва. Для оценки необходимой степени коррекции регистрируемого сигнала проведен расчет относительных интенсивностей спектральных линий калия и натрия, возбуждаемых в воздушно-ацетиленовом пламени. Далее, с учетом результатов расчета, была выбрана оптимальная дифракционная решетка-эшелетт, имеющая угол блеска для 300 нм, а также подобрана комбинация светофильтров для сближения интенсивностей регистрируемого излучения спектральных линий с резко различной чувствительностью. В результате для натрия и калия, у которых определение проводится по двум аналитическим линиям различной чувствительности, градуировочные зависимости имеют область перекрытия, включающую не менее двух значений концентрации. At the Novosibirsk Chemical Concentrates Plant, the determination of alkali metals and calcium in the range of 0.1-100 mg/l is carried out using atomic emission spectra excited in an air-acetylene flame and recorded in the range of 390-860 nm. When these elements are analyzed simultaneously in a wide range of concentrations, the accumulation time of the analytical signal (exposure) is determined by the minimum concentration of calcium. However, at this exposure, the highly sensitive lines of sodium and potassium do not provide the analysis in the entire concentration range, since at large values, the analytical signal goes into saturation. Other analytical lines of potassium and sodium in the above-mentioned operating spectral range have three to four orders of magnitude lower sensitivity. As a result, there may be a gap in the range of detectable concentrations. This paper provides a way to eliminate this gap. To evaluate the degree of correction of the recorded signal, the relative intensities of the spectral lines of potassium and sodium excited in an air-acetylene flame are calculated. Then, based on the calculation results, an optimal echelette diffraction grating with a blaze angle of 300 nm is selected, and a combination of filters is installed to equalize the recorded radiation. As a result, for sodium and potassium, for which the determination is carried out along two analytical lines, the calibration dependences have an overlap that includes at least two concentration values.

Abstract

Morbidity of inflammatory gastrointestinal (GI) diseases continues to grow resulting in worsen quality of life and increased burden on public medical systems. Complex and heterogenous illnesses, inflammatory bowel diseases (IBDs) encompass several inflammation -associated pathologies including Crohn's disease and ulcerative colitis. IBD is often initiated by a complex interplay between host genetic and environmental factors, lifestyle and diet, and intestinal bacterial components. IBD inflammatory signature was linked to the pro-inflammatory cytokine tumor necrosis factor-α (TNF-α) signaling pathway that is currently targeted by IBD therapies. Sphingolipid signaling was identified as one of the key mediators and regulators of pro-inflammatory conditions, and, specifically, TNF-α related signaling. All GI tissues and circulating immune/blood cells contain activated sphingolipid-metabolizing enzymes, including sphingosine kinases (SphK1 and SphK2) that generate sphingosine-1-phosphate (S1P), a bioactive lipid and ligand for five G-protein coupled membrane S1P receptors (S1PRs). Numerous normal and pathogenic inflammatory responses are mediated by SphK/S1P/S1PRs signaling axis including lymphocyte trafficking and activation of cytokine signaling machinery. SphK1/S1P/S1PRs axis has recently been defined as a target for the treatment of GI diseases including IBD/colitis. Several SphK1 inhibitors and S1PRs antagonists have been developed as novel anti-inflammatory agents. In this review, we discuss the mechanisms of SphK/S1P signaling in inflammation-linked GI disorders. The potential role of SphK/S1PRs inhibitors in the prevention and treatment of IBD/colitis is critically evaluated.

Abstract

Neuronopathic Gaucher disease (nGD) has a very wide clinical and genotypic spectrum. However, there is no consensus definition of nGD, including no description of how best to diagnostically separate the acute form-Gaucher type 2-from the subacute or chronic form-Gaucher type 3. In this article, we define the various forms of Gaucher disease with particular emphasis on the presence of gaze palsy in all patients with nGD. This consensus definition will help in both clinical diagnosis and appropriate patient recruitment to upcoming clinical trials.
