Pasteurisation temperatures effectively inactivate influenza A viruses in milk.

In late 2023 an H5N1 lineage of high pathogenicity avian influenza virus (HPAIV) began circulating in American dairy cattle Concerningly, high titres of virus were detected in cows' milk, raising the concern that milk could be a route of human infection. Cows' milk is typically pasteurised to render it safe for human consumption, but the effectiveness of pasteurisation on influenza viruses in milk was uncertain. To assess this, here we evaluate heat inactivation in milk for a panel of different influenza viruses.

Debiasing Sinkhorn divergence in optimal transport of cellular dynamics.

Single-cell RNA-seq analysis characterizes developmental mechanisms of cellular differentiation, lineage determination, and reprogramming with differential conditioning of the microenvironment. In this article, the underlying dynamics are formulated via optimal transport with algorithms that calculate the transition probability of the state of cell dynamics over time. The algorithmic biases of optimal transport (OT) due to entropic regularization are balanced by Sinkhorn divergence, which normally de-biases the regularized transport by centering them.

Subsequent Cancers following Non-myeloablative Conditioning for Allogeneic Hematopoietic Cell Transplantation.

We examined the risk of subsequent malignant neoplasms (SMNs) in 1720 patients with hematologic cancers given allogeneic hematopoietic grafts from 03/1998 to 08/2023 after nonmyeloablative conditioning regimens. With a median follow-up of 12 years, the cumulative incidence of SMNs was 17% (95% CI, [15%, 19%]). Most SMNs (n = 543) were non-melanoma skin cancers seen in 208 patients; unfortunately, information on these cancers was not available in the Surveillance, Epidemiology, and End Results (SEER) database for comparison with such tumors in the general population.

Electronic structure of norbornadiene and quadricyclane.

The ground and excited state electronic structure of the molecular photoswitches quadricyclane and norbornadiene is examined qualitatively and quantitatively. A new custom basis set is introduced, optimised for efficient yet accurate calculations. A number of advanced multi-configurational and multi-reference electronic structure methods are evaluated, identifying those sufficiently accurate and efficient to be used in on-the-fly simulations of photoexcited dynamics.
