Suspension of the aging face with barbed sutures offers the promise of a minimally invasive technique with diminished adverse events. The technique is in its infancy, but it has potential to be a useful and effective clinical tool as further innovations are made in the clinic and laboratory.
Bluetongue virus (BTV) infection is one of the most important diseases of domestic livestock. There are no antivirals available against BTV disease. In this paper, we present the development, optimization and validation of an in vitro cell-based high-throughput screening (HTS) assay using the luminescent-based CellTiter-Glo reagent to identify novel antivirals against BTV. Conditions of the cytopathic effect (CPE)-based assay were optimized at cell density of 5 000 cells/well in medium containing 1% FBS and a multiplicity of infection at 0.01 in 384-well plate, with Z'-values ≥ 0.70, Coefficient of Variations ≥ 5.68 and signal-to-background ratio ≥ 7.10. This assay was further validated using a 9 532 compound library. The fully validated assay was then used to screen the 194 950 compound collection, which identified 693 compounds with > 30% CPE inhibition. The ten-concentration dose response assay identified 185 structures with IC50 ≤ 100 μM, out of which 42 compounds were grouped into six analog series corresponding to six scaffolds enriched within the active set compared to their distribution in the library. The CPE-based assay development demonstrated its robustness and reliability, and its application in the HTS campaign will make significant contribution to the antiviral drug discovery against BTV disease.
After 200 person-years of exposure to spironolactone and 506 person-years of followup over 8 years, no serious illnesses thought to be attributed to spironolactone were reported. The long-term use of spironolactone in the treatment of acne in women appears to be safe. Side effects, however, are common, although not usually a cause for stopping the drug.
Early- and mid-career Mohs surgeons appear to remove tumors with similar numbers of stages regardless of their experience, case volume, or geographic location. Number of stages varies with anatomic location and tumor type. The authors have indicated no significant interest with commercial supporters.
A 23-year-old Caucasian man diagnosed with stage IVB Hodgkin's disease was referred to a university oncology section after completing 1.5 cycles of chemotherapy. His chemotherapy consisted of doxorubicin HCL, bleomycin, dacarbazine, and vinblastine, with prophylactic administration of a granulocyte colony stimulating factor. He had developed postchemotherapy complications of possible cellulitis and necrotizing fasciitis that required wound debridement. The wound and tissue cultures were negative. Biopsies taken at the time revealed a dense inflammatory infiltrate consistent with an abscess. Over the course of 2 months, the wound healed with systemic antibiotics. The patient was reluctant to resume chemotherapy for his Hodgkin's disease because of his previous presumed skin infections. However, positive emission tomographic scanning revealed disease progression. Doxorubicin, bleomycin, dacarbazine, and prophylactic pegfilgrastim (a granulocyte colony-stimulating factor), were administered. Vinblastine was excluded from the new regimen. Shortly after chemotherapy and an injection of pegfilgrastim, the patient developed poorly defined, rapidly progressive erythema, edema, and pain in his right forearm. He presented to the emergency room, was evaluated by the orthopedics service, and taken to the operating room for debridement of suspected necrotizing fasciitis. When the dermatology service consulted the following day, the patient had developed an erythematous, edematous, tender plaque on his chest. After developing two additional lesions that began to ulcerate despite treatment with imipenem, vancomycin, clindamycin, rifampin, and gentamicin, the patient consented to a skin biopsy. His wound cultures continued to be negative.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
