The synthesis and study of a series of trinuclear organometallic triaryl-1,3,5-triazinane-2,4,6-triones functionalized by d(6)-transition metal acetylides complexes at their periphery are reported. Remarkably large hyperpolarizabilities, far superior to those of related purely organic derivatives, are measured by hyper-Rayleigh scattering (HRS) for these new octupolar chromophores.

Background: Anxiety commonly affects older individuals with negative consequences on various physical and motor performances such as balance. When coupled with age-related muscular strength loss, the effects on the ability to perform daily tasks could be particularly detrimental, particularly in older women who are more susceptible to anxiety, muscular strength losses and falls. The study aimed to verify the effects of anxiety on balance performance in relation to muscular strength level in healthy older women.

Background: So-called scores are a frequently used evaluation system in clinical examinations to assess the function or limitations of a joint such as the shoulder. However, research indicates that these general scores often have limited validity for specific patient groups, such as athletes. Known as a demanding patient population, athletes have unique needs.

Patients in need of a kidney transplant have the option of receiving a kidney from a living donor or a deceased donor. Patients in the United States who do not have an available living donor typically wait on the deceased donor waiting list for an average of three to five years, although some patients may wait longer. The waiting list is very complex and intended to allocate kidneys in a fair and equitable manner.

Patients with acute kidney injury often require dialysis (AKI-D) in the outpatient setting following hospitalization. Management of the patient with AKI-D should focus on preventing further insult to the damaged kidney and recovery of kidney function. Clinical attention should include continuity of care, education, infection control, medication management, and fluid management.
