In this paper, we report on a 5-year-old girl who developed a renal stone while following the ketogenic diet to treat refractory seizure disorder. Three months after initiating the ketogenic diet, she developed severe abdominal pain and vomiting. The spot urine calcium-to-creatinine (Ca/Cr) ratio and 24-hour urine evaluation showed hypercalciuria. Computed tomography (CT) imaging revealed a sto...

Cellulose has a complex, multi-level supermolecular architecture. This natural polymer is built from superfine fibrils having diameters in the nano scale, and each such nanofibril contains ordered nanocrystallites and low-ordered nano-domains. In this review, the nano-structure of cellulose and its influence on various properties of the polymer is discussed. In particular, the ability of nano-s...

Macula densa cells are renal sensor elements that detect changes in distal tubular fluid composition and transmit signals to the glomerular vascular elements. This tubuloglomerular feedback mechanism plays an important role in regulating glomerular filtration rate and blood flow. Macula densa cells detect changes in luminal sodium chloride concentration through a complex series of ion transport...

OBJECTIVE The alcohol dehydrogenase inhibitor 4-methylpyrazole (4-MP) is a new antidote of ethylene glycol (EG) intoxication. The purpose of the present case report was to demonstrate 4-MP efficiency in EG poisoning in a 4-year-old child. METHOD AND RESULTS 4-MP Treatment was performed 7 hours after EG ingestion. Plasma EG and 4-MP concentrations were measured 2 hours after each infusion of 4...

Soil salinization and alkalization is a global problem restricting agricultural production. This study compared different fertilizer regimes (addition rate application depth) on maize growth soil quality in saline-alkali soil. Cow manure compost was applied with addition rates of 6, 12, 18 24 t·ha−1, depths 5 20 cm, along 0.6 t·ha−1 mineral fertilizer, to control treatment only application. Res...

Reinforcement with natural fibre has become a common place in range of industries the modern day. A polymer matrix can, however, boost strength reinforcing element. When it comes to fibres and polymers, they simply do not mix because their different hydrophobic hydrophilic properties. However, is designed be hydrophobic, are hydrophilic. This issue can now rectified alkalization silane binding ...

Soil alkalization triggers ion toxicity and osmotic alkaline (high pH) stresses in plants, damaging their growth productivity. Therefore, we investigated whether priming with abscisic acid (ABA) increases the tolerance of alfalfa seedlings to stress, then examined underlying molecular mechanisms. Alfalfa were pretreated ABA (10 μM) for 16 h subjected stress using a 15 mM Na2CO3 solution (pH 10....

35 36 37 Extracellular acidification induced by retinal horizontal cells has been 38 hypothesized to underlie lateral feedback inhibition onto vertebrate 39 photoreceptors. To test this hypothesis, the H-sensitive fluorophore HAF (540 hexadecanoylaminofluorescein) was used to measure changes in H from 41 horizontal cells isolated from the retina of the catfish. HAF staining conditions 42 were m...
