Low-dose radiation therapy eases knee osteoarthritis pain
AI द्वारा रिपोर्ट किया गया
A Korean clinical trial has demonstrated that low-dose radiation therapy significantly reduces pain and improves mobility in patients with mild to moderate knee osteoarthritis, outperforming placebo effects. The treatment, which uses doses far below those for cancer, showed no side effects and could serve as an alternative to medications or surgery. Results were presented at the American Society for Radiation Oncology Annual Meeting.
Plant-based serum boosts hair growth in weeks
A new topical serum containing plant extracts and growth proteins has shown promising results in increasing hair density and thickness within 56 days. Developed by researchers in Taiwan, the treatment outperformed a placebo in a small clinical trial involving 60 adults. While encouraging, experts call for larger studies to confirm its efficacy.
Immune drug reduces risk of Merkel cell carcinoma spread
A large clinical trial has shown that the immunotherapy drug pembrolizumab may help prevent the deadly spread of Merkel cell carcinoma, a rare and aggressive skin cancer, after surgery. While it did not significantly reduce overall recurrence rates, the treatment lowered the risk of distant metastases by 42%. The findings offer hope for patients facing this fast-developing disease.
Stem cell therapy lowers heart failure risk after heart attack
A large clinical trial has shown that infusing mesenchymal stem cells from umbilical cord blood shortly after a first heart attack reduces the risk of developing heart failure by nearly 60 percent over three years. The treatment, administered within three to seven days, also improved heart pumping function compared to standard care. Researchers from Shiraz University in Iran led the study, providing strong evidence for stem cells' regenerative potential.
