Vitacrystallography: Structural Biomarkers of Breast Cancer Obtained by X-ray Scattering.

With breast cancer being one of the most widespread causes of death for women, there is an unmet need for its early detection. For this purpose, we propose a non-invasive approach based on X-ray scattering. We measured samples from 107 unique patients provided by the Breast Cancer Now Tissue Biobank, with the total dataset containing 2958 entries.

Biomarker Value in the Diagnosis of Community-Acquired Pneumonia with Concomitant Chronic Heart Failure.

The diagnosis of community-acquired pneumonia (CAP) with chronic heart failure (CHF) is associated with objective difficulties. Our case-control study aims to establish whether established serum inflammatory biomarkers are relevant to the diagnosis of CAP in patients with CHF. Seventy inpatients with previously diagnosed CHF and suspected non-severe CAP were recruited and then stratified into two subgroups with confirmed and rejected diagnosis of CAP.

Concordance and Prognostic Relevance of Angiographic and Clinical Definitions of Myocardial Infarction Type.

Background: Atherothrombosis is the principal mechanism of type 1 (T1) myocardial infarction (MI), while type 2 (T2) MI is typically diagnosed in the presence of triggers (anemia, arrhythmia, etc.). We aimed to evaluate the proportions of T1 vs.

Discordance between the Clinical Presentation and Morphology of Myocardial Infarction in a Patient with Acute Post-Hemorrhagic Anemia.

While atherosclerotic plaque disruption remains the hallmark of type 1 myocardial infarction (T1MI), multiple other mechanisms provoking myocardial supply/demand mismatch (eg, anemia and tachyarrhythmias) are recognized as the potential causes of type 2 myocardial infarction (T2MI). In clinical practice, angiography is underutilized in patients with MI that have typical T2MI triggers, although the presence of these triggers and various forms of atherosclerotic coronary artery disease is not mutually exclusive. We describe a 70-year-old man that developed MI during hospitalization for gastrointestinal bleeding.

[Risk of Coronary Events in Atrial Fibrillation].

It has been established that cardiovascular events due to coronary heart disease are highly prevalent in the population of patients with atrial fibrillation. In this review, pathophysiologic mechanisms explaining this association are detailed along with supporting epidemiological evidence. Various methods for the prediction and prevention of coronary events in atrial fibrillation are iscussed, including modification of shared risk factors, antithrombotic therapy and selection of the optimal direct oral anticoagulant in terms of favourable influence on ischemic cardiac outcomes.

[Cognitive Dysfunction at the Background of Atrial Fibrillation: Clinical-Pathological Aspects, Diagnostics and Prevention, Issues of the Use of the Application of Anticoagulant Therapy].

Atrial fibrillation (AF) and cognitive dysfunction - common states with similar risk factors. Recently significant scientific epidemiological data has been received in favor of independence of effect of AF on possibility of development of cognitive dysfunction. In this review we present problems of prevalence, pathogenesis, and diagnostics of various variants of cognitive disorders at the background of AF, as well as methods of their prevention and tactics of anticoagulant therapy in the presence of cognitive disturbances.

Perylene bisbenzimidazole nonlinear dielectric material for energy storage.

A novel perylene bisbenzimidazole comprising both donor and acceptor functional groups was designed, synthesized, and characterized. This structure exhibits potentially useful physical properties, including a nonlinear dielectric response to an increasing electric field. This material can be used in energy storage devices as the dielectric part of a capacitor.

[The Value of Right Ventricular Dysfunction and Right Ventricular-Pulmonary Artery Coupling in Chronic Heart Failure: The Role of Echocardiography].

In this review article we discuss the clinical and prognostic value of echocardiographic evaluation methods of the right ventricular function and right ventricular - pulmonary artery coupling, advantages and disadvantages of echocardiography in comparison with other instrumental methods of investigation in patients with chronic heart failure.

A stable polyaniline-benzoquinone-hydroquinone supercapacitor.

A Polyaniline-Supercapacitor with quinone electrolytes remains stable over 50 000 galvanostatic charge-discharge cycles. The quinones provide superior stability by preventing the conversion of porous polyaniline to a highly reactive state. Our work shows that highly stable polymer-supercapacitors can be engineered by combining electrochemically active polymers and redox-active electrolytes with concerted electrochemical properties.

[Prognosis of hospital mortality in patients with acute decompensation of chronic heart failure].

We assessed prognostic value of clinical-laboratory and instrumental parameters in 100 patients with acute decompensation of chronic heart failure (CHF) in relation to hospital mortality. Independent predictors of lethal outcome in patients with acute decompensation of CHF were low systolic arterial pressure at admission (odds ratio [OR] 1.03, 95% confidence interval [CI] 1.

Recovery of cell nuclei from 15,000 years old mammoth tissues and its injection into mouse enucleated matured oocytes.

Here, we report the recovery of cell nuclei from 14,000-15,000 years old mammoth tissues and the injection of those nuclei into mouse enucleated matured oocytes by somatic cell nuclear transfer (SCNT). From both skin and muscle tissues, cell nucleus-like structures were successfully recovered. Those nuclei were then injected into enucleated oocytes and more than half of the oocytes were able to survive.

[Programmed ventricular stimulation in patients with acute forms of ischemic heart disease].

A group was formed of patients presenting with electrical instability of myocardium (those persons manifesting induction of ventricular tachicardia, ventricular fibrillation) after performing programmed stimulation of ventricles of the heart in 63 patients suffering from myocardial infarction and unstable angina pectoris. The main noninvasive markers of electrical instability were shown to be postinfarction cardiosclerosis, circulatory insufficiency, evolution of acute aneurysm of the heart. Institution of differentiated therapy involving correction of circulatory insufficiency with capoten, low doses of beta-blockers, specified use of antiarrhythmic drugs tailored to the individual, employing electrophysiologic testing, make it possible to improve the intrahospital diagnosis in myocardial infarction and select a group of patients to be surgically tested.

On the direction of the diffusional electric field in a mucous layer.

A simple model of the mucous layer is used to illustrate the complex relationship of the diffusional electric field direction in the layer and parameters of the latter. It is shown that the field direction may depend not only on the ratios of mobile microion diffusivities but also on the characteristics of the layer (carboxylic group concentration and dissociation constant). The electric field direction is also shown to vary across the layer under appropriate conditions.
