Near-infrared photobiomodulation of blood reversibly inhibits platelet reactivity and reduces hemolysis.

Photobiomodulation (PBM) in the red/near-infrared (R/NIR) spectral range has become widely recognized due to its anti-inflammatory and cytoprotective potential. We aimed to assess the effects of blood PBM on platelets function and hemolysis in an in vitro setting. Porcine blood samples were separated into four aliquots for this study, one of which served as a control, while the other three were subjected to three different NIR PBM dosages.

Low-level light therapy reduces platelet destruction during extracorporeal circulation.

Extracorporeal circulation causes many deleterious effects on blood cells. Low-level light therapy (LLLT) in the red/near-infrared spectral range is known for its cytoprotective properties but its use during cardiopulmonary bypass (CPB) has not yet been studied. We aimed to assess whether LLLT protects platelets during CPB.

Sheep model of haemodialysis treatment.

More than two million patients received haemodialysis (HD) in 2013. Many methods for improving dialysis therapy outcomes have been tested. Nevertheless, patients continue to experience high morbidity and mortality rates.

Serial Lung Ultrasonography to Monitor Patient With Diffuse Alveolar Hemorhage.

Diffuse alveolar haemorrhage (DAH) leads to acute respiratory failure. This is why it requires rapid diagnosis and implementation of appropriate treatment. The standard diagnosis of a patient with DAH includes laboratory tests, diagnostic imagining (X-ray of the chest, high-resolution computed tomography), and bronchoscopy with bronchoalveolar lavage.

Near infrared light induces post-translational modifications of human red blood cell proteins.

There is a growing body of evidence that near infrared (NIR) light exerts beneficial effects on cells. Its usefulness in the treatment of cancer, acute brain injuries, strokes and neurodegenerative disorders has been proposed. The mechanism of the NIR action is probably of photochemical nature, however it is not fully understood.

Application of FTIR-ATR Spectroscopy to Determine the Extent of Lipid Peroxidation in Plasma during Haemodialysis.

During a haemodialysis (HD), because of the contact of blood with the surface of the dialyser, the immune system becomes activated and reactive oxygen species (ROS) are released into plasma. Particularly exposed to the ROS are lipids and proteins contained in plasma, which undergo peroxidation. The main breakdown product of oxidized lipids is the malondialdehyde (MDA).

Galanin and vasopressin response to hyperosmotic stimulation: in vitro study.

Galanin (Gal)--a neuropeptide present in the nervous system and peripheral tissues--may be involved in the regulation of hypothalamo-neurohypophysial system function. It was shown that centrally injected galanin inhibits osmotically stimulated vasopressin (VP) secretion into the blood and reduces VP mRNA level in the supraoptic (SON) and paraventricular (PVN) hypothalamic nuclei. The aim of the present study in vitro was to investigate the influence of Gal on vasopressin release from isolated rat hypothalamus (Hth), neurohypophysis (NH) or hypothalamo-neurohypophysial explants (Hth-NH).

Predictors of depressive symptoms in patients with stroke - a three-month follow-up.

Background And Purpose: Depression is one of the most common post-stroke complications, which could impair rehabilitation outcome and quality of life, and could also increase mortality after stroke. The aim of the present study was to assess the association between demographic, socioeconomic and clinical (stroke risk factors, type of stroke, location of vascular lesion, cognitive functions) factors on the presence and severity of post-stroke depressive symptoms in patients after first ever stroke as well as on their social functioning.

Material And Methods: A prospective, cohort study with a three-month observation period was performed in seven centres.

[Sensorineural hearing loss as a consequence of carbon monoxide intoxication].

The authors describe the case of acute carbon monoxide intoxication in a 19 year old female patient, which caused, among other symptoms, bilateral sensorineural hearing loss. The symptoms, diagnostic methods and treatment with a particular regard to audiological examination were presented. Pathomechanism of carbon monoxide intoxication was also discussed.
