This pilot feasibility study evaluates the use of a hyaluronic acid-based spacing gel (Barrigel) in participants with cervical cancer undergoing chemoradiotherapy (chemoRT), including brachytherapy, as part of standard care. The primary goal is to assess feasibility. Other goals include determining whether gel placement can reduce radiation dose to nearby healthy organs (organs at risk, OAR) and improve delivery of the prescribed radiation dose to the tumor. In cervical cancer, the radiation dose to the tumor is often limited by the risk of exposing nearby sensitive organs, such as the rectum, bladder, and other pelvic structures. Vaginal packing techniques and specialized devices are used to protect these organs and ensure effective treatment. Gel spacers are inserted before radiation therapy to create space between the rectum and the cervix, reducing radiation exposure to healthy tissue. Already widely used in prostate cancer treatment in the U.S., gel spacers may also help improve tumor control and reduce treatment-related toxicity in cervical cancer.

The purpose of this research is to develop and test new Magnetic Resonance Imaging (MRI) methods that look at how muscles and tissues under the skin (myofascial tissues) move and respond to pressure. The investigators want to see how these tissues differ between healthy people and people with pain or injury, and how they change after hands-on treatment (Tuina therapy). The results will also be compared to a group that receives standard care without Tuina therapy. The main questions this study aims to answer are: 1. Can MR elastography (MRE) show changes in how the fascia and the layers between muscles move and stretch before and after manual therapy? 2. Do changes seen on MRE scans match changes in pain, function, and other symptoms reported by participants? 3. Can MRE measurements before treatment help predict which participants are most likely to improve with manual therapy? In this randomized controlled trial, participants with myofascial pain will be randomly assigned (randomized) to either the Tuina group or the Usual Care group following a home-based care program without manual therapy. All treatments are noninvasive, hands-on techniques commonly used in clinical practice to reduce tissue tightness and improve movement. Participants will be asked to undergo three MRI scans and to complete questionnaires and other standard clinical assessments about their pain, physical function, and quality of life.

Glucagon secretion from α-cells has long been viewed as primarily a counterregulatory mechanism - e.g. an agent with a role to prevent blood sugar from decreasing to levels that compromise function. Our group, along with other researchers, have begun to identify a much more complex role for α-cells, raising questions about when and how glucagon may influence blood glucose levels. This proposal looks to detail proglucagon peptide secretion from α-cells and the impact this has on β-cell function and glucose tolerance, in preclinical studies of human islets and translational studies in human subjects. This protocol registration describes Aim 2 from this NIH grant which involves 2 study populations and separate protocols but addresses a common question. Aim 3 in the grant is focused on a separate hypothesis and will be conducted and published separately from Aim 2.

In this study, researchers will learn more about a drug called felzartamab in people who have received a kidney transplant and later developed a condition called microvascular inflammation (MVI). MVI is a type of injury to small blood vessels in the transplanted kidney and may be a sign of rejection by the body. It can lead to serious kidney problems over time. The main goal of the study is to learn about the effect felzartamab has on inflammation in the transplanted kidney. The main question researchers want to answer is: • How many participants have no signs of active inflammation in the transplanted kidney after 24 weeks of treatment with felzartamab? Researchers will also study how felzartamab affects kidney function, immune activity, and overall health. They will monitor safety through kidney biopsies, lab tests, and by recording adverse events throughout the study. Adverse events are unwanted health problems that may or may not be caused by the study drug. The study will be done in 2 parts as follows: - Participants will be randomly assigned to receive either felzartamab or a placebo. A placebo looks like the study drug but contains no real medicine. - In Part A, participants will receive their assigned drug for 24 weeks. Neither the researchers nor the participants will know who is receiving felzartamab or placebo. - Part B will last another 28 weeks. All participants will receive felzartamab and both participants and researchers will know this. - All treatments will be given by intravenous (IV) infusion at the study site. - Participants will have kidney biopsies at the start of the study, at week 24, and at week 52 to help measure changes in inflammation. - Participants will stay in the study for about 1 year.
