Dimensionality engineering of metal halide perovskites.

Metal halide perovskites are a class of materials that are ideal for photodetectors and solar cells due to their excellent optoelectronic properties. Their low-cost and low temperature synthesis have made them attractive for extensive research aimed at revolutionizing the semiconductor industry. The rich chemistry of metal halide perovskites allows compositional engineering resulting in facile tuning of the desired optoelectronic properties.

Fatal Balamuthia mandrillaris brain infection associated with improper nasal lavage.

We report the case of a 69-year-old female who presented with a chronic nasal skin rash, new onset focal seizure, and a cerebral ring-enhancing lesion after a year of improper nasal irrigation. Despite aggressive and novel anti-amoebic treatment, she died as a result of a Balamuthia mandrillaris brain infection.

Comparison of breast cancer to healthy control tissue discovers novel markers with potential for prognosis and early detection.

This study was initiated to identify biomarkers with potential value for the early detection of poor-outcome breast cancer. Two sets of well-characterized tissues were utilized: one from breast cancer patients with favorable vs. poor outcome and the other from healthy women undergoing reduction mammaplasty.

Joint curettage arthrodesis technique in the foot: a histological analysis.

Unlabelled: Arthrodesis via joint contour preservation using the curettage method has become popular in foot and ankle surgery to avoid segmental shortening and the need to bone graft. Despite its popularity, the effect of joint curettage has never been histologically evaluated. Knowledge of the histological appearance after joint curettage would be helpful to the foot and ankle surgeon to better understand the function of joint surface preparation for arthrodesis.
