Diaci v3.0: chromosome-level assembly, de novo transcriptome, and manual annotation of Diaphorina citri, insect vector of Huanglongbing.

Background: Diaphorina citri is an insect vector of "Candidatus Liberibacter asiaticus" (CLas), the gram-negative bacterial pathogen associated with citrus greening disease. Control measures rely on pesticides with negative impacts on the environment, natural ecosystems, and human and animal health. In contrast, gene-targeting methods have the potential to specifically target the vector species and/or reduce pathogen transmission.

Structure of PDE3A-SLFN12 complex reveals requirements for activation of SLFN12 RNase.

DNMDP and related compounds, or velcrins, induce complex formation between the phosphodiesterase PDE3A and the SLFN12 protein, leading to a cytotoxic response in cancer cells that express elevated levels of both proteins. The mechanisms by which velcrins induce complex formation, and how the PDE3A-SLFN12 complex causes cancer cell death, are not fully understood. Here, we show that PDE3A and SLFN12 form a heterotetramer stabilized by binding of DNMDP.

Florence Nightingale's contribution to contemporary nursing ethics.

Florence Nightingale brought nursing from a disreputable and immoral vocation into the honest and ethical profession that is enjoyed today by emphasizing strict morals in the personal and work lives of her nursing students. In modern day, ethical principles guide the nursing profession and have many relevant connections to Nightingale's morals. Just as the high moral character of Nightingale's nurses helped nursing rise to a profession in her day, teaching and following ethical principles is crucial in furthering the nursing profession in our day.
