[Impact of comorbid chronic heart failure with preserved left ventricular ejection fraction on the management of elderly cancer patients before and after total resections].

Objective: To determine the predictors of safe enhanced recovery after surgery in elderly cancer patients with comorbid chronic heart failure (CHF) and preserved left ventricular ejection fraction (LVEF).

Material And Methods: There were 75 patients over 65 years old (mean 73.6±5.

"Vitruvian" precursor for gas phase deposition: structural insights into iridium β-diketonate volatilities.

New data on the thermodynamic properties of the melting and sublimation of a series of volatile iridium(i) complexes [Ir(cod)(L)] with cyclooctadiene-1,5 (cod) and β-diketones (L = RC(O)CHC(O)R') have been obtained with differential scanning calorimetry and vapor pressure measurements. Combining experimental, empirical and theoretical methods, ways to estimate difference in heat capacities between gas and crystal phases have been suggested. An effect on the volatility in introducing the simplest alkyl, fluorinated alkyl and aryl terminal groups (R and R') into the chelate ligand has been explained in terms of a detailed crystal packing analysis supported by a quantum chemical calculation of crystal lattice energies.

[Dynamics of osteogenesis associated with inoculation of autologous stromal cells from rat adipose tissue (experimental-morphological study)].

Experiment was evaluated on 40 male Wistar rats. On the experimental model of mandible injury, bone autologous graft from tibia was placed on the surface of mandible (host bone). In the main experimental group, consisting of 20 animals, autologous rat adipose-derived stromal cells (ADSCs) were inoculated in space between autograph and host bones.

[An improved single-layer suture in the surgery of small and large intestines].

The methods and results of using single-layer interrupted intestinal suture in operations on the small and large intestines are presented. Using the suture decreases the number of complications associated with this technique, improves the direct results of operations and reduces postoperative lethality both in urgent and planned surgery. The proposed intestinal suture is thought to be justified in connecting similar and dissimilar parts of the intestinal tube in the variants of longitudinal, transversal, terminal, lateral and termino-lateral interintestinal anastomoses.
