A study found that PRO 2000 gel reduced HIV and HSV infectivity by at least 1000-fold, with no significant inflammatory response. The results suggest a potential safe and effective vaginal microbicide for preventing sexually transmitted infections.
Researchers have developed an injectable gel that can speed up the repair of torn cartilage. The biodegradable material is composed of hyaluronic acid and can be hardened with ultraviolet light or visible light, creating a growth environment for cartilage-producing cells to grow new cartilage.
A new hydrogel sealant, made from biocompatible dendritic macromolecules and poly(ethylene glycol), seals corneal incisions more effectively than suturing or self-sealing, preventing infection and trauma.
A study found that combining testosterone gel with sildenafil improved erectile function in men with low testosterone, who failed to respond to sildenafil alone. The combination therapy showed significant improvements in erectile function, orgasmic function, and overall satisfaction.
The study found significant improvements in mood and sexual performance, with sustained increases in lean body mass and bone mineral density over 3.5 years. Researchers observed minimal skin irritation and no major adverse effects, paving the way for testosterone gel as a safe treatment option.
The Proteomics Shared Resource at OHSU enables faster and more precise protein identification, processing up to 180 samples in six hours. The lab's advanced technology, including a robotic arm and mass spectrometer, helps researchers analyze proteins and identify their composition.
Researchers Francesca O'Kane used pea proteins to study the behavior of plant proteins when heated, forming a gel that can be repeatedly heated without losing strength or flexibility. This unique structure provides insight into protein aggregation and will help predict texture changes in meat substitutes.
Scientists develop pentablock polymers that form micelles in response to changes in temperature and pH, resembling how biomolecules react. These stable polymers could be used to deliver drugs or gene therapies, and have shown promise in preliminary studies.
Researchers at the University of Toronto have created a new gel-like substance that guides neural cells through channels, providing a greater surface area for neural stimuli transmission. This breakthrough could lead to stronger signals in regenerated nerves, paving the way for regenerative medicine applications.
Researchers created a gel that effectively increases isolated single wall carbon nanotube concentrations without bundling. The resulting nematic nanotube gels exhibit beautiful defect patterns and mechanical strains, opening up potential for novel composites and applications.
Researchers at Johns Hopkins Kimmel Cancer Center have identified a new compound that accelerates genetic discovery by reducing the time and cost associated with DNA separation. Sodium boric acid has been found to replace outdated solutions in electrophoresis, resulting in significant improvements.
A recent study found a significant association between the breakdown of the vitreous gel and the development of nuclear cataracts. The researchers discovered that high levels of vitreous liquefaction were strongly correlated with cataract formation, even after accounting for age.
A new treatment using 15% azelaic acid gel has been shown to be more effective than metronidazole gel in reducing rosacea symptoms. Patients who used the azelaic acid gel experienced a greater reduction in redness and lesion count compared to those who used metronidazole gel.
Researchers have created a simpler, cheaper way to make and fit prosthetics by using a gel instead of plaster. The new process has been tested on 10 leg amputees with no differences found in the success of the two types of sockets.
Researchers have developed a hydrophobically modified hydrogel that could restore accommodative ability and enable individuals to focus on near and far objects. The material is soft and viscoelastic, similar to the natural human lens, and has the potential to be injectable, reducing invasive surgery.
Researchers at NIST used a special facility to study 'shake gels,' materials that firm up and relax in response to external stimuli. They discovered the polymer's oxygen atoms, not hydrogen atoms, attach to clay, and water binds to surfaces in a perpendicular arrangement.
A multicentre hospital-based case-control study found that transdermal estrogen replacement therapy is not associated with an increased risk of venous blood clots in postmenopausal women. In contrast, oral estrogen replacement therapy was linked to a significantly higher risk of developing venous thromboembolism.
A study of 664 patients with moderate papulopustular facial rosacea found that azelaic acid 15% gel significantly reduced redness and the number of inflammatory lesions. The treatment also showed promise for improving overall quality of life, with patients reporting comfort and satisfaction with the product.
BufferGel, a vaginal microbicide, maintains normal vaginal acidity to kill sperm and germs, preventing pregnancy. The compound is currently in advanced clinical trials for its ability to block HIV transmission.
A randomized, double-blind study found a significant reduction in symptom severity and duration when treating with zincum gluconicum nasal gel, even at 48 hours after illness onset. The treatment significantly shortened the median duration of cold symptoms by 4 days compared to placebo.
The study reveals how aluminum floc forms in polluted streams, binding to toxic metals and transporting them downstream, harming fish and other aquatic animals. Understanding the molecular pathways of this process may lead to practical solutions to prevent the reactions.
A recent study found that nonoxynol-9 spermicide may increase the risk of HIV-1 infection in women due to vaginal lesions caused by frequent use. In contrast, low-frequency use showed no harm or benefit. The findings highlight the need for alternative vaginal microbicides.
Researchers are developing innovative devices that promise to simplify blood glucose monitoring, reducing the risk of complications such as blindness and kidney disease. A symposium will showcase advancements in noninvasive and minimally invasive blood glucose monitoring, including a 'smart tattoo' that glows to reveal glucose levels.
A new treatment approach using cisplatin/epinephrine gel has shown significant promise in treating advanced head and neck cancer. The study found that 29% of patients experienced tumor responses, with 19% achieving complete responses.
Biomedical engineer Shelly Sakiyama-Elbert has designed a novel nerve repair system that uses a gel-filled tube to deliver growth factor proteins stimulating nerve regeneration. The system promotes peripheral nerve regeneration in preliminary rat studies and shows promise for spinal cord repair.
A study led by REI investigators found that testosterone gel replacement significantly improved sexual motivation and performance, reduced fat mass, and increased lean body mass in hypogonadal men. The treatment was also found to increase bone mineral density and cause minimal skin irritation.
Researchers investigated ten alcohol-based gels and four hand rinses, concluding they were less effective than a reference disinfectant within 30 seconds. The introduction of these gel formulations in hospitals could lead to increased risk of cross-transmission due to shorter application times.
A recent study by Ohio State University found that the DentiPatch, a small adhesive patch containing lidocaine, delivers longer and deeper relief from dental pain. The patch's anesthetic effects last up to 45 minutes, whereas traditional gel-based treatments only last about a minute.
Researchers develop biomimetic gel that binds to glucose molecules, potentially triggering insulin release in diabetics. The gel's sensing mechanism could be incorporated into implantable devices, providing therapy for type one diabetes.
Researchers have created star polymer gels with potential applications in delivering high concentrations of drugs to specific areas in the body, such as tumors. These gels can also recognize and remove substances like cholesterol from the blood through a process called molecular imprinting.
