In the title complex, [Cu(C(5)H(5)N(2)O(2))(C(14)H(18)N(3)O)(H(2)O)]·1.33H(2)O, the Cu(II) ion is coordinated in a slightly distorted square-pyramidal environment. The basal plane is formed by two N atoms from a 2-(5-ethyl-2-pyridyl-κN)-4-isopropyl-4-methyl-5-oxo-4,5-dihydroxy-imidazol-1-ide ligand and by one O atom and one N atom from a 5-methyl-1H-pyrazole-3-carboxyl-ate ligand. The apical position is occupied by a water mol-ecule. In the crystal structure, O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds lead to a three-dimensional supra-molecular network.

Pharmacists are highly accessible healthcare professionals with presence in communities, hospitals, and clinics. They are well positioned to expand their roles in supporting individuals with mental health challenges. A cross-sectional study was conducted to identify trends in how pharmacists assess, monitor, identify, and care for patients with mental health challenges.

The question remains whether surgery is truly a game-changer for all patients or whether its benefits are more nuanced depending on individual patient factors and disease characteristics. As the oncology community continues to explore this question, a modern breast surgeon should emphasize the importance of further prospective trials and personalized treatment strategies that consider not only surgery but also the growing arsenal of available systemic therapies.

A new one-pot approach was developed for the construction of pyrano[3,2-]chromene-2,5-diones by reacting 4-hydroxycoumarins with ethyl 3-oxo-3-phenylpropanoates in the presence of ammonium salts or aminocrotonates under solvent-free conditions. The title compounds were formed by intramolecular cyclization through new C-C and C-O bonds. Structure assignment of compound 3e was confirmed by single crystal X-ray analysis.

Background: AD/ADRD diseases currently impact more than 6 million people in the US. Rare forms of AD/ADRD are caused directly and unambiguously by genetic mutations. However, most AD/ADRD burden is complex in etiology and thought to result from an interplay among multiple incompletely understood genetic, biochemical, lifestyle, environmental and psychosocial risk factors.
