NCT07369297
Accurate evaluation of dental pulp health is essential to avoid unnecessary endodontic treatments. In routine dental practice, pulp sensibility is commonly assessed using electric pulp testing and thermal (cold) testing. However, these tests depend on patient perception and may be influenced by various factors such as systemic diseases, nerve damage, anxiety, trauma, or medication use. Diabetic polyneuropathy is a common complication of diabetes mellitus and may alter peripheral nerve function, potentially affecting dental pulp sensibility test responses. This clinical study aims to evaluate how the severity of diabetic polyneuropathy influences dental pulp sensibility responses and masseter inhibitory reflex (MIR) parameters. The MIR is an objective neurophysiological reflex that allows quantitative assessment of trigeminal nerve function. In this study, individuals with mild diabetic polyneuropathy, severe diabetic polyneuropathy, and healthy controls will be evaluated. All participants will undergo electric pulp testing, cold testing, and MIR measurements using standardized protocols. The primary hypothesis of this study is that increasing severity of diabetic polyneuropathy leads to reduced dental pulp sensibility responses and altered MIR parameters compared to healthy individuals. It is further hypothesized that conventional pulp sensibility tests may produce false-negative results in patients with advanced neuropathy. The findings of this study are expected to contribute to more accurate endodontic diagnosis and improved understanding of orofacial neurophysiological changes in diabetic patients.

Gut microbiota play a key role in polyphenol metabolism, participating in the breakdown of dietary components and producing various small molecule metabolites that affect human health. However, little is currently known about how gut microbes metabolize dietary compounds and produce bioactive metabolites. This study aims to use metabolomics to precisely identify food-derived metabolites in the blood to investigate whether probiotics (BLa80, LRa05) can enhance the breakdown of dietary components and improve their absorption and utilization in the human body.

NCT07068698
This randomized controlled study will aim to investigate the effects of thumb manipulation on hand grip strength, function, and sensation in healthy individuals. A total of 60 volunteers aged between 18 and 50 years will be recruited from Ortadağ Special Education and Rehabilitation Center. Participants will be randomly assigned to either a chiropractic manipulation group (n=30) or a control group (n=30), with an equal distribution of males and females in each group. The intervention group will receive thumb manipulation twice weekly for 4 weeks, while the control group will not receive any intervention. Outcome measures will include two-point discrimination (assessed with a discriminator), hand grip strength (measured using a dynamometer), pinch strength (evaluated with a pinch meter), and hand function (measured by the Duruöz Hand Index). Statistical analyses will be performed with a significance level set at p\<0.05. It is expected that participants in the manipulation group will show greater improvements in all measured parameters compared to the control group, suggesting a positive effect of thumb manipulation on hand-related sensorimotor functions in healthy individuals.

NCT06157398
A diet with a higher intake of fish and fruits, and vegetables, has shown promise in reducing inflammation and oxidative stress in the body. Intake of a diet with these components has been linked to fewer respiratory symptoms and lower rates of lung disease in multiple studies. In addition, emerging research suggests that a diet with these components may have the power to protect the body against some of the effects of exposure to air pollution. In this study, participants will receive food, meals, and counseling designed to increase their dietary intake of fish, fruits, and vegetables. The research team will test the change in diet and learn ways to optimize the participants' experience.

The investigators will conduct a parallel-group, placebo-controlled, randomized, double-blind ascending dose Phase I study of dietary supplementation in healthy individuals to evaluate safety and to determine the pharmacologically effective dose (ED).
NCT06591403
This study aims to examine peripheral oxygen saturation values measured in different body positions and fingers in healthy young adult individuals. The research was planned in a quasi-experimental design. The research population consisted of students/healthy young adults studying at Bursa Uludağ University Faculty of Health Sciences between January 2024 and May 2024. The research sample consisted of a total of 200 volunteer individuals who met the research limitations. The research data were collected using the Individual Introduction Form and Peripheral Oxygen Saturation Monitoring Form. A pulse oximeter was placed simultaneously on the index and middle fingers of each participant\'s active hand while they were in an upright sitting position. After the pulse oximeter was placed on both fingers for one minute, stable values seen on its screen for at least three seconds were recorded. Then, the participants were placed in a supine position, and after a 10-minute rest, similar measurements were repeated with a pulse oximeter placed on the index and middle fingers of the active hand.

NCT01687127
Periconceptional supplementation with folic acid - the synthetic form of the B-vitamin folate - reduces the occurrence of adverse pregnancy outcomes such as spina bifida. The underlying biochemical mechanisms for how folic acid affects health outcomes however are unknown. The naturally occurring form 5-methyltetrahydrofolate (5-MTHF) is now available and discussed as an adequate substitute to folic acid. This study aims to determine the effect of folic acid compared to 5-MTHF on cellular mechanisms. Stable isotope tracer protocols will be used that allow determining the effect of folic acid on the dynamics of metabolic pathways in the human body. Hypothesis: Supplementation with high-dose folic acid alters the turnover rate of folate dependent pathways in healthy humans; but 5-MTHF does not. Genetic variations in a key enzyme of the folate metabolism will aggravate the effect of folic acid on the metabolic pathways.

NCT04772417
The 1-minute sit-to-stand test (1MSTS) is a widely used functional capacity test and has promising predictive potential. Current standards of practice suggest the use of a chair with a standardized height. However, this practice makes the test more demanding for taller individuals than for shorter individuals. This implies over- or underestimation of functional capacity depending on body morphology. Therefore, the aim of this study is to investigate the influence of knee joint angle, femur length and bodyweight on the 1MSTS performance in healthy subjects with different morphology.

NCT05358561
This study is a pioneering study in which the effect of the consumption of cakes produced with the addition of cereal-like products such as chia and flax seeds, which have high soluble fiber content, on blood glucose and insulin values, and the effect on the satiety response of individuals after consumption of cakes, will be a pioneer in many subjects. As a result of the study, the relationships between the changes in the investigated parameters and the possible changes in these parameters will be revealed. The results obtained suggest that foods rich in soluble fiber such as chia and flaxseed and foods produced with the possible synergetic effect of chia and flaxseed are used in healthy and safe products suitable for our consumption habits, and that these products are both protective and protective against the development of complications such as obesity and type 2 diabetes, cardiovascular diseases. The investigators think that it may also play a role in preventing its progress.
