Autoimmunity in acute ischemic stroke and the role of blood-brain barrier: the dark side or the light one?

This article presents a synopsis of the current data on the mechanisms of blood-brain barrier (BBB) alteration and autoimmune response in acute ischemic stroke. Most researchers confirm the relationship between the severity of immunobiochemical changes and clinical outcome of acute ischemic stroke. Ischemic stroke is accompanied by aseptic inflammation, which alters the brain tissue and exposes the co-stimulatory molecules of the immune system and the neuronal antigens.

[Characteristics of postoperative cerebral dysfunction depending on the type and position of the implanted prosthetic heart valve].

Aim: To study the prevalence and structure of postoperative cerebral dysfunction depending on the type and position of the implanted prosthetic heart valve in patients who underwent surgery for the acquired heart valve disease.

Material And Methods: The study included 115 patients (70 men and 45 women; 64 [56; 72] years old), who underwent elective replacement or repair surgery for the acquired heart valve disease.

Results And Conclusion: The postoperative cerebral dysfunction was diagnosed in 40.

[Perioperative stroke in heart valve surgery: pathogenesis, clinical findings, diagnosis, prevention, treatment].

Aim: To study risk factors, characteristics of clinical symptoms and diagnosis, and possibilities of prevention of perioperative stroke and other clinical types of cerebral dysfunction in main types of heart valve surgery.

Material And Methods: The study included 83 patients, aged 63 (54; 70) years, undergoing heart valve surgery with cardiopulmonary bypass.

Results: Postoperative cerebral dysfunction was diagnosed in 37.

Eye-safe near-infrared trace explosives detection and imaging.

We report the development of a non-contact no-reagents system operating in the eye-safe 1560-1800 nm wavelength range for standoff trace detection of explosives and high-speed imaging. Experimental results are provided for a number of chemicals including explosives on a variety of surfaces at sub-microgram per cm concentration. Chemically specific images were collected at 0.
