BIOMARKERS

This study is testing whether a blood test measuring a protein called p-Tau217 can accurately diagnose Alzheimer's disease. Currently, diagnosis requires a spinal tap to analyze spinal fluid. Researchers will compare the blood test results with the standard spinal fluid tests in …

This study looks at whether certain DNA changes in saliva can help doctors diagnose oral cancer more accurately. Researchers will collect saliva from 30 patients with oral cancer and 30 healthy people, then compare the DNA markers before and after surgery. The goal is to create a…

This study looks at whether getting a dental implant right after a tooth is pulled (immediate placement) or waiting a while (delayed placement) changes how the mouth heals. Researchers will measure healing markers in saliva and gum fluid from 24 adults over 30 days. The goal is t…

This study looks at blood clots removed from people having a stroke to see if their makeup is linked to what caused the stroke, how well treatment works, and how the person recovers. Researchers will also test participants' blood for related markers. The goal is to learn more abo…

This study is creating a tool to estimate a person's 'biological age'—how old their body really is—rather than just counting birthdays. Researchers will collect health, lifestyle, and lab data from 3,500 volunteers across Russia. The goal is to better understand aging and help pr…

This study looks at fluid from jaw cysts to learn more about how these cysts develop. Researchers will measure certain proteins (MMP-8, MMP-9, RANKL, MIP-1alpha) in the fluid taken during a routine diagnostic procedure. About 25 people with jaw cysts will take part. The goal is t…

This study is testing whether artificial intelligence can make CT scans of the heart better at predicting future heart attacks. Researchers will follow 10,000 adults who are already getting a heart CT for medical reasons. Participants will also give blood samples, have an ECG, an…

This study looks at fluid from around the lungs (pleural effusion) to find new markers that could help diagnose lung adenocarcinoma. Researchers will compare samples from 100 patients with and without cancer. The goal is to see if these markers can make diagnosis easier and more …

This study is testing whether adding blood and urine tests (biomarkers) to a computer risk score can better predict which hospitalized patients will develop severe acute kidney injury (AKI). About 800 adults at high risk will be enrolled at two hospitals. Researchers will collect…

This study looks at how doctors in the Democratic Republic of Congo treat fevers and whether new tools—like a simple blood test (CRP), a WHO antibiotic guide, and electronic decision aids—can help them use antibiotics more wisely. Researchers will follow 500 adults and children w…
