Ligand-Directed Actinide Oxo-Bond Manipulation in Actinyl Thiacalix[4]arene Complexes.

Understanding the chemistry of the inert actinide oxo bond in actinyl ions AnO22+ is important for controlling actinide behavior in the environment, during separations, and in nuclear waste (An = U, Np, Pu). The thioether calixarene TC4A (4-tert-butyltetrathiacalix[4]arene) binds equatorially to [AnO2]n+ (An = U, Np) forming a conical pocket that differentiates the two trans-oxo groups. The 'ate' complexes, [A]2[UO2(TC4A)] (A = [Li(DME)2], HNEt3) and [HNEt3]2[NpO2(TC4A)], enable selective oxo chemistry.

Functional Regrowth of Norepinephrine Axons in the Adult Mouse Brain Following Injury.

It is widely believed that axons in the central nervous system of adult mammals do not regrow following injury. This failure is thought, at least in part, to underlie the limited recovery of function following injury to the brain or spinal cord. Some studies of fixed tissue have suggested that, counter to dogma, norepinephrine (NE) axons regrow following brain injury.

Advances in Drug Treatments for Companion Animal Obesity.

Companion animal obesity has emerged as a significant veterinary health concern globally, with escalating rates posing challenges for preventive and therapeutic interventions. Obesity not only leads to immediate health problems but also contributes to various comorbidities affecting animal well-being and longevity, with consequent emotional and financial burdens on owners. While past treatment strategies have shown limited success, recent breakthroughs in human medicine present new opportunities for addressing this complex issue in companion animals.

Salvage surgery for recurrent or residual hypopharyngeal squamous cell carcinoma: A systematic review.

Background: This systematic review aggregates the data of studies that include site-specific analyses of patients undergoing salvage surgery for residual or recurrent hypopharyngeal squamous cell carcinoma.

Methods: The primary outcomes are disease-free, disease-specific, and overall survival (DFS, DSS, and OS, respectively). Secondary outcomes include complications and postoperative feeding requirements.

Healthcare Provider Perceptions of the Use of Medical Interpretation in Primary Care.

Objectives: Sixty-three percent of Latinos/as/x in Alabama, speak English "not well" or "not at all." Effective provider-patient communication is the foundation of successful clinical interactions. Medical interpretation is important to the healthcare provision for patients with limited English proficiency (LEP).
