Scedosporium Infection in Recipients of Kidney Transplants from Deceased Near-Drowning Donor.

Scedosporium aurianticum infection developed in 2 recipients of kidney transplants in India, acquired from the same deceased near-drowning donor. Given the substantial risk for death associated with Scedosporium infection among solid-organ transplant recipients, safety protocols for organ transplantation from nearly drowned donors should be thoroughly revaluated and refined.

Results of the Modified Brosch Approach and Rehabilitation of Mural Unicystic Ameloblastoma of the Mandible in a Young Patient.

Although radical surgery results in craniofacial deformity, functional damage, and aesthetic harm, all of which have an immediate negative impact on a patient's quality of life, it also has the lowest recurrence rate for biologically aggressive subtypes of mural unicystic ameloblastomas. The oral approach removes the lingual cortex and exposes the entire buccal cortical plate in the area of the ascending and horizontal ramus to the full extent of the lesion. There is no obvious distortion of the soft tissues of the face following the modified Brosch procedure, which is also associated with rapid bone regeneration.

Characterization of Z-DNA Using Circular Dichroism.

The B-DNA to Z-DNA transition is a remarkable conformational change in DNA, which was originally observed in poly-GC DNA in the presence of high salt concentration. This eventually prompted the observation of the crystal structure of Z-DNA, a left-handed double-helical DNA, at atomic resolution. Despite advances in Z-DNA research, the application of circular dichroism (CD) spectroscopy as the fundamental technique to characterize this unique DNA conformation has remained constant.

Cancer care continuum at a tertiary care centre in India during the Covid-19 pandemic and nationwide lockdown: Healthcare delivery through telemedicine.
