Sir, Dr Yuan recently reported the interesting case of a 23year-old dialysis patient with extensive calcifications, including lung calcifications [1]. We similarly encountered a young patient who had developed severe lung calcifications, which proved reversible after intensifying the dialysis regimen and optimization of the calcium–phosphate regulation. This patient is a 29-year-old woman with ...

The modeling of real neuronal networks by close-to-biology circuits can contribute to a better understanding these from circuit theoretical point view. This potentially lead novel design principles for electrical circuits. process involves the mimicking measured activity, which is often only available as calcium imaging recordings. In this work, we develop wave digital model emulator capable ca...

PURPOSE To determine optimal MR gradient-echo sequences for the visualization of calcium in neurologic MR. METHOD The dependence of signal intensity and image contrast on the imaging parameters repetition time, echo time, flip angle, and spoiling were measured for hydroxyapatite samples. Calculations of signal intensity were shown to correspond to these measures. RESULTS Optimum detectabili...

india is one of the largest producers of onion in the world producing over 13,920,000 metric tons. storage is a major problem which leads to spoilage, and microbes play an important role in the spoilage. in this present study, biotechnologically important strains have been isolated from the spoiled onions by using appropriate enriched media. two potential strains were isolated and a brief compa...

Genetically encoded calcium indicators (GECIs) are powerful tools for systems neuroscience. Recent efforts in protein engineering have significantly increased the performance of GECIs. The state-of-the art single-wavelength GECI, GCaMP3, has been deployed in a number of model organisms and can reliably detect three or more action potentials in short bursts in several systems in vivo. Through pr...

The optimization of powder x-ray diffraction (PXRD) for the study of cheese crystals was the focus of this study. A survey was conducted of various manifestations of calcium lactate crystals on the rindless surface and within mechanical openings of Cheddar cheese using PXRD. The diffraction reference card database contained a card that was entitled calcium lactate pentahydrate and corresponded ...

Neural circuit optimization occurs through sensory activity-dependent mechanisms that refine synaptic connectivity and information processing during early-use developmental critical periods. Fragile X Mental Retardation Protein (FMRP), the gene product lost in Fragile X syndrome (FXS), acts as an activity sensor during critical period development, both as an RNA-binding translation regulator an...

The search for an efficient drug or inhibitor in the formation process of kidney stones has been a promising research topic towards reducing risks disease. However, several challenges have faced investigating most common constituents stones, calcium oxalate and its hydrate forms (COM, COD COT). This study focuses on preparation structural characterization (TG, XRD, FTIR, SEM) hydrates presence ...
