Safety profile of miltefosine in the treatment of cutaneous leishmaniasis.

Cutaneous leishmaniasis (CL) is a neglected tropical disease that poses a significant public health challenge in Brazil and worldwide. Miltefosine, the only orally administered drug available for CL, was recently incorporated into Brazil's treatment protocols following recommendations by the World Health Organization (WHO) and revisions by national health authorities. While this represents an important advancement, miltefosine is associated with frequent gastrointestinal side effects and potential teratogenic risks, necessitating careful patient eligibility assessments and close clinical monitoring throughout treatment.

Analysis of ASCL1/NEUROD1/POU2F3/YAP1 Yields Novel Insights for the Diagnosis of Olfactory Neuroblastoma and Identifies Sinonasal Tuft Cell-Like Carcinoma.

The diagnosis and treatment of sinonasal small round epithelial/neuroepithelial malignancies depend on the expression of conventional neuroendocrine markers (NEMs), such as synaptophysin, chromogranin A, INSM1, and CD56/NCAM1. However, these tumors remain diagnostically challenging because of overlapping histologic and immunohistochemical features. The transcriptional regulators ASCL1, NEUROD1, POU2F3, and YAP1 are novel NEM (nNEM) used for the subtyping of small-cell lung cancer (SCLC).

Ultra-uniform perovskite crystals formed in the presence of tetrabutylammonium bistriflimide afford efficient and stable perovskite solar cells.

Compositional engineering of organic-inorganic metal halide perovskite allows for improved optoelectrical properties, however, phase segregation occurs during crystal nucleation and limits perovskite solar cell device performance. Herein, we show that by applying tetrabutylammonium bistriflimide as an additive in the perovskite precursor solution, ultra-uniform perovskite crystals are obtained, which effectively increases device performance. As a result, power conversion efficiencies (PCEs) of 24.

Pleural Kaposi Sarcoma in Two HIV-Positive Patients.

Kaposi sarcoma is a neoplasm caused by human herpes virus 8 (HHV-8) that commonly presents as subcutaneous lesions but can also involve visceral organs such as the gastrointestinal and pulmonary systems. Diagnosis is achieved through histopathological analysis of cutaneous lesions or lymph nodes. In this study, we report two patients, recently diagnosed with HIV, who were later found to have cutaneous and visceral (pleural) Kaposi sarcoma.

Inhibiting Interfacial Nonradiative Recombination in Inverted Perovskite Solar Cells with a Multifunctional Molecule.

Interface-induced nonradiative recombination losses at the perovskite/electron transport layer (ETL) are an impediment to improving the efficiency and stability of inverted (p-i-n) perovskite solar cells (PSCs). Tridecafluorohexane-1-sulfonic acid potassium (TFHSP) is employed as a multifunctional dipole molecule to modify the perovskite surface. The solid coordination and hydrogen bonding efficiently passivate the surface defects, thereby reducing nonradiative recombination.
