A multiple session dataset of NIRS recordings from stroke patients controlling brain-computer interface.

This paper presents an open dataset of over 50 hours of near infrared spectroscopy (NIRS) recordings. Fifteen stroke patients completed a total of 237 motor imagery brain-computer interface (BCI) sessions. The BCI was controlled by imagined hand movements; visual feedback was presented based on the real-time data classification results.

One-Pot Synthesis of CHA/ERI-Type Zeolite Intergrowth from a Single Multiselective Organic Structure-Directing Agent.

We report the one-pot synthesis of a chabazite (CHA)/erionite (ERI)-type zeolite intergrowth structure characterized by adjustable extents of intergrowth enrichment and Si/Al molar ratios. This method utilizes readily synthesizable 6-azaspiro[5.6]dodecan-6-ium as the exclusive organic structure-directing agent (OSDA) within a potassium-dominant environment.

Heparin-coated iron oxide nanoparticles: application as a liver contrast agent, toxicity and pharmacokinetics.

The prepared heparin-coated iron oxide nanoparticles (Hep-IONPs) contrasted cholangioma tumors in the liver in MRI. The NPs were not toxic to rats and rabbits after 14 days of consecutive IV injections as observed from the monitoring of the body weight and biochemical and hematological parameters. No embryotoxic or immunotoxic side effects of the material were detected.

Degradation kinetic study of ZIF-8 microcrystals with and without the presence of lactic acid.

The zeolitic imidazolate framework ZIF-8 (Zn(mim), mim = 2-methylimidazolate) has recently been proposed as a drug delivery platform for anticancer therapy based on its capability of decomposing in acidic media. The concept presumes a targeted release of encapsulated drug molecules in the vicinity of tumor tissues that typically produce secretions with elevated acidity. Due to challenges of and examination, many studies have addressed the kinetics of ZIF-8 decomposition and subsequent drug release in phosphate buffered saline (PBS) with adjusted acidity.

Treatment of Moderate to Severe Acne and Scars With a 650-Microsecond 1064-nm Laser and Isotretinoin.

Background: Laser procedures for acne and acne scars have traditionally been postponed for at least 6 to 8 months after the end of systemic isotretinoin therapy. Lower dosages with more modern laser devices having unique energy parameters of high power in microsecond pulse durations have made it possible to administer laser therapy during or shortly after completion of isotretinoin therapy, thus reducing the risk of side effects of isotretinoin.

Methods: Patients with moderate to severe facial acne (n=46) and atrophic scars enrolled in a 6-month study.

[A method for studying intravascular platelet aggregation in vitro].

A simple available method for evaluating intravascular platelet aggregation is proposed. It consists in graphic recording of disaggregation of platelet-rich citrate plasma, which indicates the degree of intravascular aggregation. Intravascular aggregation is notably increased in coronary patients and negligible in normal subjects.

[A graphic method of determining plasminogen].

The author suggests a graphic method for plasminogen estimation. The euglobulin fraction lysis is recorded in the hemocoagulographer cuvette, this essentially improving the accuracy of studies.

[Clinical value of studying fibrinogen degradation products in patients with ischemic heart disease].

Study of fibrinogen degradation products in patients with angina pectoris and acute myocardial infarction proved to be of clinical importance. Their content in patients with acute myocardial infarction was increased more considerably than that in patients with angina pectoris. This parameter can be used for the differential diagnosis of angina pectoris and acute myocardial infarction.

[Immunologic diagnosis of intravascular blood clotting and intravascular thrombus formation among patients with ischemic heart disease].

Rabbit plasmas immune to fibrinogen/fibrin and thrombin, with antibody titres of 1:1024, were obtained by rabbit immunization with fibrinogen and thrombin. Immunologic methods were shown to be capable of detecting thrombinemia and increased fibrinogen/fibrin levels, as well as reduced titres of anti-thrombin and anti-fibrinogen/fibrin antibodies, i. e.

[Effect of lipoproteins of different classes on platelet aggregation].

The influence of high-, low- and very-low-density lipoproteins on platelet aggregation was examined in coronary patients and normal subjects. Preincubation with high-density lipoproteins was shown to drastically inhibit platelet aggregation capacity both in normal subjects and coronary patients. Preincubation with a mixture of low- and very-low-density lipoproteins had no significant effect on platelet aggregation.

[Interrelationship of lipid metabolic disorders and hemostasis in arteriosclerosis].

Proceeding from the obtained data, the authors conclude that two factors are of paramount importance in the pathogenesis of atherosclerosis: 1) lipid infiltration, 2) fibrin and platelets deposits on the vascular wall. It seems hardly proper to oppose the lipid-infiltrationab of pathogenesis of atherosclerosis to the thrombogenic one, since they do not necessarily exclude one another. Moreover, they seem to present two aspects of a single process: on the one hand, lipids increase platelet adhesion and aggregation on the vascular wall; on the other hand, platelets during aggregation help the penetration of beta-lipoproteins into the arterial wall by increasing the permeability of the endothelium and by adsorbing cholesterol-rich beta-lipoproteins on their own surface.
