Cukriniu diabetu sergančių ligonių blauzdos arterijų kraujotaką atkuriančių metodų įvertinimas /
… that diabetes does not affect restoration of blood circulation to the lower leg arteries after reconstructive operations in the early postoperative period for patients with critical limb ischemia. Diabetes does have a tendency to worsen bypass function and long-term restoration of blood …

Shape dependent iron oxide nanoparticles for simultaneous imaging and therapy
… ideal for stem cell labelling, however the low blood circulation time (<15 min) limited their use, in vivo. In order to increase the circulation time, the size must be increased without altering the magnetic properties of the nanoparticles. Therefore, the ultrasmall nanoparticles were trapped in …

Beta-Lapachone Nanotherapeutics for Lung Cancer Therapy
… dissociation of β-lap with HPβ-CD led to short blood circulation times and rapid distribution among all organs. By contrast, a micellar formulation of β-lap did not cause hemolysis, and displayed increased blood circulation times and relatively high and sustained accumulation in tumors. β-Lap …

Mobility-Aid Smart Pants with Embedded Harness for Daily Use
… to improve patient’s cardiovascular health, blood circulation, and disease prevention. However, gait training is often inaccessible due to the heavy equipment required, impractical to purchase for individual use; giving patients more optionality in their mobility aids through everyday …

Molekulární mechanismy vývoje koronárních cév
… grows, but also acts as a pump that drives the blood circulation of the embryo. With advancing development, it is necessary to ensure an adequate supply of oxygen to the heart, for that reason coronary arteries are formed. Each cardiomyocyte is surrounded by at least one capillary, therefore the …

Heartbeat rate modulation mediated by the ventral nerve cord in the honey bee, APIS MELLIFERA
… assumed neurohormonal regulation was disrupted (blood circulation to the abdomen was blocked). Heartbeat patterns from these latter two groups were then compared with the baseline data from the former three groups. Results showed that normal modulation occurring during feeding and locomotion …

Engineering M13 bacteriophage platforms for cancer therapy applications
… based cancer detection by optimizing for phage blood circulation and tumor extravasation. Secondly, we have added to our cancer targeting M13 platform collection by cloning for chlorotoxin display on the tail p3 capsid protein of M13. Chlorotoxin can induce passage across blood-brain barrier, …

Analysis and visualization of temporal variations in video
… such as variation in human skin color due to blood circulation and small mechanical movements, can be extracted for further analysis, or exaggerated to become visible to an observer. Our techniques can also attenuate motions and changes to remove variation that distracts from the main temporal …

Applying a microfluidic 'deformability cytometry' to measure stiffness of malaria-infected red blood cells at body and febrile temperatures
Red blood cells (RBCs) undergo repeated deformation as they traverse blood vessel, capillaries and splenic cords; RBC deformability is therefore crucial in maintaining normal blood circulation. During falciparum malaria, parasite proteins interact with the spectrin network of host RBCs, moderately …

Early-Stage Research and Design of a Diagnostic Sensor for Peripheral Vascular Disease
Peripheral Vascular Disease (PVD) is a blood circulation disorder that involves the narrowing and blocking of arteries in the lower extremities of the body. Symptoms of PVD include pain and restricted mobility, and as the disease progresses, it can lead to high risk of heart attack and stroke. PVD …

Effects of DFO-Induced Hypoxia on Key Signaling Mediators
… injury can cause hypoxia through a decrease in blood circulation to bodily regions or decrease cardiac output they can also associate with hypoxia-induced pain. Clinically, opioids, such as morphine, are used to modulate pain. The mu-opioid receptors (MORs) are one of three main types of opioid …

Developing biophysical markers for anemic disorders through advancing interferometric microscopy
Erythrocytes, better known as red blood cells, among various functions, are mainly tasked with the oxygen transport in vertebrates through blood circulation. Red blood cells are packed with the hemoglobin, an oxygen-binding molecule, and have unique biophysical properties that are critical in …

3-D Bio-inspired Microenvironments for In Vitro Cell Migration
… depart the primary tumor site and enter the blood circulation, they spread through the body and will likely initiate a new tumor site. Therefore, understanding the cell migration and stopping the spread in the initial stage is the utmost of importance. In this dissertation, we have proposed a …

Development of Bio-Impedance microprobes for Integration with a Smart Biopsy tool
… to its exterior into the healthy tissue or the blood circulation during its retraction from the tumor. These few cancer cells can then serve as seeds for the malignant tumor to grow in the healthy tissue. Cauterization using extreme heat or cold can destroy cells in the region and minimize the …

Innate Immunity in Chickens: In Vivo Responses to Different Pathogen Associated Molecular Patterns
… intradermal test site along with concurrent blood sampling, we examined the time-course, phenotype, and severity of PAMP (LPS, PGN, MDP, or poly I:C) -elicited leukocyte and cytokine responses in both the peripheral blood circulation (automated hematology analysis) and at the local …

Targeting brain inflammation with bioconjugated nanoparticles
… ideal for surface modification and ensuring long blood circulation half-life. Cell viability was determined using the MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] conversion assay and a Lactate Dehydrogenase (LDH) Cytotoxicity Detection Kit. At each concentration of cellulose …
