The esterification of galacturonic acid with methanol and/or acetic is important for the structural analysis pectin. Although several methods have been reported determining degree methylesterification (DM) and acetylation (DAc), present study compares optimizes three (titration, FT-IR HPLC) using commercial citrus pectin (CP). Our results showed that DM CP was 47.0%, 47.6% 48.0% as determined b...

Different forms of titration curves obtained by ELISA for serum antibodies, monoclonal antibodies and polyreactive immunoglobulins were considered. A new interpretation of dose-dependent titration curves was suggested. It was shown that our interpretation of dose-dependent titration curves for antibodies which are presented in some biological liquids allow obtaining additional information about...

TOPIC: Sleep Disorders TYPE: Original Investigations PURPOSE: Solriamfetol (Sunosi®) is a dopamine/norepinephrine reuptake inhibitor approved (US and EU) to treat excessive daytime sleepiness (EDS) in adults with narcolepsy (75-150 mg/d) or obstructive sleep apnea (OSA) (37.5-150 mg/d). Titration strategies for hypothetical patient were analyzed understand factors physicians consider when initi...

BACKGROUND Levodopa-carbidopa intestinal gel (LCIG; Duodopa®) is used for continuous infusion in advanced Parkinson's disease. To achieve optimal effect, the LCIG dose is individually titrated, traditionally conducted during hospitalization in Sweden. However, dose adjustment depends on surrounding conditions, physical activity, and emotional stress, which is why titration at home could be bene...

The formol titration, as described by Srrensen, 1 has been most useful in the determination of amino-acids and especially in following the course of hydrolysis of proteins. The method as originally described could not be used for accurate determinations of small quantifies of amino-acids owing to the difficulty of determining the exact end-point. The value obtained also depends on the point at ...

Principal component analysis (PCA) technique is used for the precise determination of pK values from titration curves of amphoteric molecules, such as proteins and amino acids. A regression model is developed based on the effective charge of amphoteric molecules. Partial domain method, a new algorithm, is introduced to minimize or remove errors in extracted pK values from experimental (titratio...

The feasibility of measuring CO2 content in biogas was evaluated in this research. Firstly, Curtipot pH simulator was used to visualize the titration behaviors of various percentages of dissolved CO2 in a wide range of concentrations of NaOH solution. As a general output of those simulations, it was shown that when the titration curves of different CO2 conte...

Background and Objectives: Vaccination is the major strategy to protect nurses against infection with hepatitis B virus. However, some nurses do not produce sufficient amount of anti-HBsAg antibody required for immunity against infection. Chronic occupational stress has been proposed as a risk factor to humoral immunity. Given that nursing staff is exposed to occupational stress risk, this stud...

BACKGROUND Short children born small for gestational age (SGA) are treated with a GH dose based on body size, but treatment may lead to high levels of IGF1. The objective was to evaluate IGF1 titration of GH dose in contrast to current dosing strategies. METHODS In the North European Small-for-Gestational-Age Study (NESGAS), 92 short pre-pubertal children born SGA were randomised after 1 year...

Various data have demonstrated inadequate glycemic control amongst Asians with type 2 diabetes mellitus (T2DM), possibly on account of suboptimal titration of basal insulin-an issue which needs to be further examined. Here we review the available global and Asia-specific data on titration of basal insulin, with a focus on the use of insulin glargine 100 U/mL (Gla-100). We also discuss clinical ...
