Essential oil blend and monensin for feedlot steers consuming backgrounding and finishing diets: growth performance, methane emissions using the GreenFeed system, and feeding behavior.

A study was conducted to assess growth performance, methane (CH) emissions, and feeding behavior of feedlot steers consuming backgrounding and finishing diets with an essential oil blend (EO), monensin (Mon), and their combination (EO + Mon). The study was structured as a 2 × 2 factorial, with two feed additive treatments (Control, EO) and two monensin treatments (no Monensin, Monensin). One hundred Angus × steers were evenly distributed across each treatment into four pens, and each dietary phase consisted of four, 28-d periods.

Multi-Omic Atlas reveals cytotoxic phenotype and ROS-linked metabolic quiescence as key features of CTL-resistant HIV-infected CD4 T-cells.

Cytotoxic T-lymphocytes (CTL) exert sustained pressure on reservoirs of HIV-infected cells that persist through years of antiretroviral therapy (ART). This selects for latently infected cells, but also potentially for cells that express HIV but possess intrinsic CTL resistance. We demonstrate that such resistance exists in HIV-infected CD4 T-cells that survive rigorous CTL attack and map CTL susceptibility to cell identities and states defined by single-cell multi-omics and functional metabolic profiling.

Comparison of Predictable Ability Measure Using Examinations and Nursing Licensure Success.

End-of-program predictive examinations have been in existence in nursing education for over 10 years. Nursing schools have used these examinations to prepare students on the testable content from National Council of State Boards of Nursing (NCSBN), which has been delivering the NCLEX-RN since 1994. Nursing students, in the final semester of the nursing program, took the Predictable Ability Measurement Readiness (PAMR) 1 and/or 2.

Synthesis and Characterization of Thallium-Texaphyrin Nanoparticles and Their Assessment as Potential Delivery Systems for Auger Electron-Emitting Tl to Cancer Cells.

Thallium-201 is an Auger electron-emitting radionuclide with significant potential for targeted molecular radiotherapy of cancer. It stands out among other Auger electron emitters by releasing approximately 37 Auger and Coster-Kronig electrons per decay, which is one of the highest numbers in its category. It has also a convenient half-life of 73 h, a stable daughter product, established production methods, and demonstrated high radiotoxicity.
