Anti-Inflammatory Effects of Step Electrical Stimulation on Complete Freund's Adjuvant (CFA) Induced Rheumatoid Arthritis Rats.

Rheumatoid arthritis is a chronic inflammatory disease that affects joints and induces pain and swelling. We evaluated the anti-inflammatory effects of step electrical stimulation (SES) in this study. SES was carried out by increasing the voltage (3 V/s) from 5 V to 100 V for 60 cycles.

Near-Infrared Light Emitting Diode Based Non-Invasive Glucose Detection System.

Diabetes mellitus is a common disease that has affected people since antiquity. The complexity of diabetes mellitus lies in the fact that it requires continuous management in order to prevent serious complications. Various methods for managing diabetes mellitus through monitoring blood glucose levels have been studied and developed, and the most widely used method includes using an invasive blood glucose meter.

Local-dependency of morphological and optical properties between breast cancer cell lines.

Breast cancer is the most malignant type of cancer in women and is a global health problem, with mortality by metastasis being the main factor among others. Currently, detection and diagnosis of breast cancer is achieved through a variety of procedures, such as clinical examination, medical imaging, biopsy, and histopathological analysis. In contrast, spectroscopic analysis has a variety of advantages such as being noninvasive, not destroying biological materials, and not requiring additional histological analysis.

Cell viability, adhesion and function of RAW 264.7 macrophages on fluorinated xerogel-derived nitric oxide permeable membrane for the application of cellular sensing.

Organically modified xerogels have an advantage over gas sensing applications due to their open, rigid structure and hydrophobicity. Here we evaluated the biocompatibility of xerogel-derived nitric oxide (NO) permeable membranes modified with fluorinated functional groups for application in cellular sensing by growing RAW 264.7 macrophages on them.

Simultaneous, real-time measurement of nitric oxide and oxygen dynamics during cardiac ischemia-reperfusion of the rat utilizing sol-gel-derived electrochemical microsensors.

In this study, we simultaneously measured nitric oxide (NO) and oxygen (O2) dynamics in the myocardium during myocardial ischemia-reperfusion (IR) utilizing sol-gel modified electrochemical NO and O2 microsensors. In addition, we attempted to clarify the correlation between NO release in the ischemic period and O2 restoration in the myocardium after reperfusion, comparing a control heart with a remote ischemic preconditioning (RIPC)-treated heart as an attractive strategy for myocardial protection. Rat hearts were randomly divided into two groups: a control group (n=5) and an RIPC group (n=5, with RIPC treatment).

Real time measurement of myocardial oxygen dynamics during cardiac ischemia-reperfusion of rats.

Because oxygen plays a critical role in the pathophysiology of myocardial injury during subsequent reperfusion, as well as ischemia, the accurate measurement of myocardial oxygen tension is crucial for the assessment of myocardial viability by ischemia-reperfusion (IR) injury. Therefore, we utilized a sol-gel derived electrochemical oxygen microsensor to monitor changes in oxygen tension during myocardial ischemia-reperfusion. We also analyzed differences in oxygen tension recovery in post-ischemic myocardium depending on ischemic time to investigate the correlation between recovery parameters for oxygen tension and the severity of IR injury.
