Water Effective Diffusion Coefficient in Dairy Powder Calculated by Digital Image Processing and through Machine Learning Algorithms of CLSM Micrographs.

Rehydration of dairy powders is a complex and essential process. A relatively new quantitative mechanism for monitoring powders' rehydration process uses the effective diffusion coefficient. This research focused on modifying a previously used labor-intensive method that will be able to automatically measure the real-time water diffusion coefficient in dairy powders based on confocal microscopy techniques.

Investigation of breakage behavior and its effects on spray-dried agglomerated whey protein-lactose powders: Effect of protein and lactose contents.

Particle breakage of dairy powders occurs easily during many processes, reducing the powder functionality. The characteristics of particles and the applied stress from processing conditions on the particles are 2 main factors that can be manipulated to reduce breakage. In this study, we explored the effect of whey protein and lactose contents on dynamic breakage in agglomerated whey protein-lactose powders to provide useful information, in terms of particle characteristics, for controlling unwanted dairy powder breakage.

Breakage behaviour and functionality of spray-dried agglomerated model infant milk formula: Effect of proteins and carbohydrates content.

This study explored the effect of protein content (whey protein and casein) and carbohydrate content (lactose, sucrose, and maltodextrin) on the breakage behaviour and its influence on spray-dried agglomerated model infant milk formula. Whey protein powders were bigger in particle size, weaker in structural strength, and marginally more irregular in shape, which resulted in better rehydration properties but more breakage than pure casein powders. Similarly, sucrose samples had better rehydration properties and higher glass transition temperatures but suffered more breakage than maltodextrin and pure lactose powders because of their bigger particle size.

The Effect of High Protein Powder Structure on Hydration, Glass Transition, Water Sorption, and Thermomechanical Properties.

Poor solubility of high protein milk powders can be an issue during the production of nutritional formulations, as well as for end-users. One possible way to improve powder solubility is through the creation of vacuoles and pores in the particle structure using high pressure gas injection during spray drying. The aim of this study was to determine whether changes in particle morphology effect physical properties, such as hydration, water sorption, structural strength, glass transition temperature, and α-relaxation temperatures.

A COMPARATIVE STUDY OF LIPID PROFILE AND LEPTIN RESISTANCE IN CHILDREN WITH METABOLIC SYNDROME DEPENDING ON HYPERTENSION IN KYIV.

Objective: The aim: To compare lipid metabolism and leptin levels among the children with and without hypertension to identify associated risk factors for the course of metabolic syndrome in children.

Patients And Methods: Materials and methods: This observational, cross-sectional study recruited children from the Rheumocardiology Department of Children's Clinical Hospital No 6 in Kyiv, with metabolic syndrome, identification of waist-to-height ratio, leptin level, homeostasis model assessment of insulin resistance and lipid profile. The main group included 41 children with metabolic syndrome and hypertension and the control group included 40 children with metabolic syndrome without hypertension.

Early functional and metabolic disorders in children with type I diabetes mellitus and diabetic nephropathy.

Type 1 diabetes (T1D) is mainly a disease of children and young adults. The onset of disease is associated with 3 classical symptoms: polydipsia, polyphagia, and polyuria. Hyperglycaemia is the main and primary metabolic disorder in T1D.

The Influence of Composition and Manufacturing Approach on the Physical and Rehydration Properties of Milk Protein Concentrate Powders.

This study investigated the physical and rehydration properties of milk protein concentrate (MPC) powders with five different protein contents (i.e., 38.

Water sorption and hydration in spray-dried milk protein powders: Selected physicochemical properties.

Low and high protein dairy powders are prone to caking and sticking and can also be highly insoluble; with powder storage conditions an important factor responsible for such issues. The aim of this study focused on the bulk and surface properties of anhydrous and humidified spray-dried milk protein concentrate (MPC) powders (protein content ~40, 50, 60, 70 or 80%, w/w). Water sorption isotherms, polarized light and scanning electron micrographs showed crystallized lactose in low protein powders at high water activities.

Effects of lipids on the water sorption, glass transition and structural strength of carbohydrate-protein systems.

Encapsulant systems are gaining wide practical interest due to their functional and nutritional properties. This paper was focusing on understanding structural relaxations in that systems near glass transition temperature. Freeze-dried trehalose-whey protein isolate-sunflower oil systems with various ratios of the last were used as a carbohydrate-protein-lipid food model.

Structural strength analysis of amorphous trehalose-maltodextrin systems.

Fundamental knowledge of physical state of materials gives practically important information for food, biological and pharmaceutical industry. Based on Williams-Landel-Ferry (WLF) equation, the strength concept was introduced. This concept provides a simple parameter, S, to express resistance of solids to flow above the glass transition temperature.

The Effectiveness and Safety of a Homeopathic Medicinal Product in Pediatric Upper Respiratory Tract Infections With Fever: A Randomized Controlled Trial.

We investigated the clinical effectiveness of a homeopathic add-on therapy in a pediatric subpopulation with upper respiratory tract infections (URTI) in a randomized, controlled, multinational clinical trial. Patients received either on-demand symptomatic standard treatment (ST-group) or the same ST plus a homeopathic medication (Influcid; IFC-group) for 7 days. Outcome assessment was based on symptom and fever resolution and the Wisconsin Upper Respiratory Symptom Survey-21 (WURSS-21).

[The preparation of pediatrics physicians in different countries of the world].

The authors carried out the analysis of training system of doctors - pediatrists in the different countries of Europe and USA. It is shown, that there exist three models of the organization of rendering of medical care to the children: pediatric model (the doctor - pediatrist as a primary part of rendering of medical care of children), system of the general practice (the doctor - pediatrist carries out functions of the adviser) and the combined system which is based on the listed above models. Pointed that the system of the general practice is inherent in the countries with a high level of incomes on one inhabitant of the country.

[Efficacy of the pharmacotherapy of secondary enuresis in children].

43 children, 8-16 years old, suffering from secondary nocturnal enuresis were treated using different schemes. The most effective treatment of patients with only nocturnal enuresis was using a complex of nootropic psychostimulant medications (Fesam, B vitamins, apilak, Ca Glycerophosphat) with xanthinol nicotinat and combined treatment with the help of day-light therapy (motivating and regimen measures).

[The characteristics of lymphocyte membrane function in pyelonephritis patients].

Lipid, phospholipid and fattyacid spectrum of membranes of lymphocytes isolated from the peripheral blood of patients with pyelinephritis were studied. It has been established that in the active phase of the disease the ratio of certain lipidic and phospholipidic fractions gets changed, in the first place, those of free cholesterin, phospholipids, phosphatidilcholin, phosphatidilethanolamine. In the fattyacid spectrum, the content of oleic, linoleic and, in particular, arachidonic acid, has been noted to get reduced.
