Excess Enthalpies Analysis of Biofuel Components: Sunflower Oil-Alcohols Systems.

This study addresses the pressing issues of energy production and consumption, in line with global sustainable development goals. Focusing on the potential of alcohols as "green" alternatives to traditional fossil fuels, especially in biofuel applications, we investigate the thermochemical properties of three alcohols (n-propanol, n-butanol, n-pentanol) blended with sunflower oil. The calorimetric analysis allows for the experimental determination of excess enthalpies in pseudo-binary mixtures at 303.

Excess Enthalpies for Binary Mixtures of the Reactive System Acetic Acid + n-Butanol + n-Butyl Acetate + Water: Brief Data Review and Results at 313.15 K and Atmospheric Pressure.

The data on molar excess enthalpies, HmE, for the binary mixtures acetic acid + n-butanol, acetic acid + n-butyl acetate and n-butanol + n-butyl acetate at 313.15 K and atmospheric pressure were obtained with use of the C80 isothermal mixing calorimeter (Setaram). The correlation of the data was carried out using the NRTL model and Redlich-Kister equation.

Impact of Layered Perovskite Oxide LaYbAlO on Structure and Transport Properties of Polyetherimide.

This study aims to improve properties of Ultem polyetherimide (PEI) by incorporating up to 2 wt% additives of the perovskite oxide LaYbAlO (LYA). The structure of dense PEI/LYA films was characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) in combination with an analysis of their elemental composition using energy-dispersive spectroscopy (EDS). The PEI/LYA films exhibit a two-layer structure.

Osmolyte-Like Stabilizing Effects of Low GdnHCl Concentrations on d-Glucose/d-Galactose-Binding Protein.

The ability of d-glucose/d-galactose-binding protein (GGBP) to reversibly interact with its ligands, glucose and galactose, makes this protein an attractive candidate for sensing elements of glucose biosensors. This potential is largely responsible for attracting researchers to study the conformational properties of this protein. Previously, we showed that an increase in the fluorescence intensity of the fluorescent dye 6-bromoacetyl-2-dimetylaminonaphtalene (BADAN) is linked to the holo-form of the GGBP/H152C mutant in solutions containing sub-denaturing concentrations of guanidine hydrochloride (GdnHCl).

We observed 137 patients, 72 of whom (53%) had hypertension in II trimester of pregnancy, and 65 patients (47%) who had hypertension in perimenopausal period. The comprehensive clinical and instrumental examination was carried out in all patients, including simultaneous 24-hour ambulatory blood pressure (BP) recording (with BP pattern), assessment of vegetative tone using the vegetative index (index Kerdo). Sympathetic/adrenergic activity (SAA) was quantified as β-receptor binding (β-RB).

[Effect of acetylsalicylic acid on the indicators of thrombocytic hemostasis in patients with myocardial infarction].

The examination of 50 patients with acute myocardial infarction indicated that enhanced platelet functional activity was a prognostically unfavourable sign and associated with a higher risk for myocardial infarction complications. The application of aspirin, 250 mg daily, in patients with high platelet functional activity in the acute period of the disease failed to produce a beneficial antiaggregatory effect.

[Emoxipin in reperfusion of ischemic myocardium in dogs: effects on infarct size and plasma creatine kinase activity].

The effects of synthetic antioxidant emoxypine on infarct size and plasma creatine kinase (CK) activity was studied on open-chest anesthetized dogs with 180-min myocardial ischemia followed by reperfusion. Emoxypine (10 and 40 mg/kg) was injected intravenously, beginning since 120th min of coronary artery occlusion. Emoxypine (10 mg/kg) resulted in infarct size limitation and reduction in plasma CK activity.

The paper is concerned with the assessment of hypophyseal somatotropic, prolactotropic and thyrotropic functions during the TRH test in patients with non-insulin-dependent diabetes mellitus with noticeable signs of diabetic retinopathy. No changes in hypophyseal somatotropic, prolactotropic and thyrotropic functions during the TRH test were noted in patients with non-insulin-dependent diabetes mellitus without diabetic microangiopathies.

[Levels of various pituitary and pancreatic hormones in the blood of patients with non-insulin-dependent diabetes mellitus].

The level of pituitary hormones (somatotropin and prolactin) and pancreatic hormones (insulin and glucagon) was measured by radioimmunoassay in blood of patients with insulin-independent diabetes mellitus with and without diabetic microangiopathies, in the state of decompensation and during treatment. Forty-four patients aged 26 to 60 years were examined. Some patients with insulin-independent diabetes with and without diabetic microangiopathies demonstrated an elevation of blood insulin and glucagon.

[Somatotropin and prolactin levels in patients with insulin-dependent diabetes mellitus].

Radioimmunoassay was used to measure the content of somatotropic hormone and prolactin in the blood of patients with insulin-dependent diabetes in relation to the duration and degree of diabetic complications in a state of decompensation and during compensation. To have a more descriptive idea of the interrelation between prolactin and somatotrophic hormone (STH), the prolactin/STH index was introduced (the ratio of prolactin indicators to those of STH). Altogether 66 patients aged from 16 to 50 years were examined.

Twelve men, aged 17 to 43 years, with insulin-depending diabetes mellitus were examined during the decompensation stage. The patients were divided into 2 groups, depending on the disease duration. The stage of the hypothalamic-hypophyseal system was evaluated according to the blood plasma STH, TTH and prolactin levels and after intravenous injection of the Soviet thyroliberin (TRH).

[Investigation of DNA complexes with histones F3 and F3+F2a2].

Characteristic viscosity, sedimentation constant and optical anisotropy were studied of the complexes formed between DNA and histone fractions F3 and F3+F2a2. The parameters mentioned continuously change with the increase of protein content within the complex. Analysis of experimental data shows that binding of a histone bads to a decrease of size and thermodynamic rigidity of the DNA molecule.
