Prevention of refeeding syndrome: Evaluation of an enteral refeeding protocol for severely undernourished children.

Objectives: Refeeding syndrome (RS) defines the deleterious clinical and metabolic changes occurring during nutritional support of severely malnourished patients. Pediatric guidelines to prevent and treat RS are scarce and highly variable. This study aimed to evaluate the effectiveness and safety of an enteral refeeding protocol in severely undernourished hospitalized children with anorexia nervosa (AN) or organic diseases (OD).

Preparation and evaluation of ozone micro-nano bubbles ice for Litchi precooling.

Ozone (O) is an effective agent for post-harvest fruit preservation against diverse microorganisms. In this study, a cost-effective ozone micro-nano bubbles ice (O-MNBI) was prepared, characterized, and subsequently used to precool litchi. The optimal protocols for O-MNBI production were as follows: water (2 °C, pH = 7) was pumped into a micro-nano O bubble generator for 10 min aeration treatment.

Omega-3 Fatty Acids, Lecithin, Sterols, Vitamins and Lipid Oxidation of Olein and Super Olein Fractions of Fish Oil Produced by Winterization.

To concentrate omega-3 fatty acids (-3) in fish oil (FO), olein and super olein fraction (OF) of FO were produced by winterization. For this purpose, FO was slowly cooled to -50°C (24 h), the mixture of crystallized and non-crystallized phases was separated, filtrate was coded as OF (yield 32%), 35% of OF was kept for storage study and analytical purpose, remaining 65% was further slowly cooled down to -75°C (24 h) and filtered, filtrate was coded as super olein (SF, yield 23%). GC-MS analysis showed that unsaturated fatty acids increased due to successive winterization.

Fast Neuronal Calcium Signals in Brain Slices Loaded With Fluo-4 AM Ester.

Staining brain slices with acetoxymethyl ester (AM) Ca dyes is a straightforward procedure to load multiple cells, and Fluo-4 is a commonly used high-affinity indicator due to its very large dynamic range. It has been shown that this dye preferentially stains glial cells, providing slow and large Ca transients, but it is questionable whether and at which temporal resolution it can also report Ca transients from neuronal cells. Here, by electrically stimulating mouse hippocampal slices, we resolved fast neuronal signals corresponding to 1%-3% maximal fluorescence changes.

Electrochemical Detection of Hydrogen Peroxide at High Concentrations Using Hastelloy G35 Electrode.

The detection of hydrogen peroxide (HO) at elevated concentrations while eliminating oxygen interference presents a significant challenge. Nickel-based stainless steel, such as Hastelloy G35, has shown excellent corrosion resistance. However, it has never been used in electroanalysis.
