Actinidia arguta (sarunashi) juice inhibits lung cancer in mice
Researchers from Okayama University found that Actinidia arguta (Sarunashi) juice and its component isoquercetin inhibit lung cancer development in mice, accelerating DNA repair and suppressing Akt-mediated growth signaling. The study suggests Sarunashi juice as an attractive candidate for chemoprevention.
Oncotarget: Ibuprofen disrupts protein complex in colorectal cells
Researchers found that ibuprofen inhibits the alternative splicing event generating RAC1B, overexpressed in BRAF-mutated colorectal tumors. Ibuprofen disrupts a WNK1/GSK3β/SRPK1 protein kinase complex, promoting nuclear exclusion of SRPK1 and SRSF1.
Leprosy declines in Morocco after implementation of preventive drug
Since 2012, the number of leprosy cases in Morocco has decreased significantly, with an average annual decline of -16.83%. This improvement is attributed to the implementation of single dose rifampicin chemoprophylaxis, which has helped to interrupt transmission and reduce disability.
HIV: The benefits of prophylaxis of tuberculosis are confirmed
Long-term follow-up confirms that isoniazid prophylaxis reduces both severe morbidity and mortality among HIV-infected individuals. The study provides evidence for the WHO recommendation of isoniazid preventive therapy in HIV-positive patients, even with early antiretroviral treatment.
Seasonal malaria chemoprevention in Senegalese children lowers overall malaria burden
