Dermoscopic Findings in Trichoblastoma.

Published: November 2015

Trichoblastoma is a benign cutaneous neoplasm that is clinically and histologically similar to basal cell carcinoma. We report the dermoscopic features seen in 2 cases of facial trichoblastoma. One case presented with very short, delicate, scarcely branching telangiectases against a pearly white background. In the second case, the veins were also short and scarcely branching, but they were arranged in a crown pattern, with white striae and milia-like cysts. Although dermoscopic evidence of fine, scarcely branching telangiectases is not specific to a diagnosis of trichoblastoma, these features may be useful for differentiating this neoplasm from nodular basal cell carcinoma.

Constraint programming is known for being an efficient approach to solving combinatorial problems. Important design choices in a solver are the , designed to lead the search to the best solutions in a minimum amount of time. However, developing these heuristics is a time-consuming process that requires problem-specific expertise.

Controlled oligomerization in water to hyperbranched ethylene oligomers.

The production of high molecular weight polyethylene particles in aqueous environments has received considerable attention, yet reports on the formation of polyethylene oil within water remain scarce. Herein, we present findings that demonstrate the oligomerization of ethylene by certain iminopyridyl Pd(II) catalysts in water, resulting in the synthesis of hyperbranched ethylene oligomers. It is worth highlighting the intriguing observation that these catalysts exhibited a remarkable catalytic longevity in aqueous medium and ultimately facilitated the generation of a substantial liquid polyolefin phase from water.

Acceptor Elongation Boosted Intersystem Crossing Affords Efficient NIR Type-I and AIE-Active Photosensitizers for Targeting Ferroptosis-Based Cancer Therapy.

Photosensitizers (PSs) featuring type I reactive oxygen species (ROS) generation and aggregation-induced emission (AIE) activity offer a promising solution to achieve non-invasive and precise theranostics. However, the reported AIE luminogens (AIEgens) with both AIE characteristic and strong type-I ROS generation are still scarce and the structure-property relationship is still unclear. Herein, an innovative acceptor elongation boosted intersystem crossing (AEBIC) design strategy has been proposed to endow the AIEgen strong type-I ROS producibility.

Background: Multiple studies suggest a plausible connection between urologic cancers and branched-chain amino acids (BCAAs) breakdown metabolic enzymes. Nevertheless, there is scarce exploration into the variations in circulating BCAAs. In our research, we utilize bidirectional, two-sample Mendelian randomization (MR) analysis to predict the link between BCAAs levels and three distinct types of urological tumors.
