Chemistry. 2021 Mar 17;27(16):5180-5190. doi: 10.1002/chem.202004496. Epub 2021 Jan 12.

The selectivity and rate enhancement of bifunctional hydrogen bond donor-catalyzed Diels-Alder reactions between cyclopentadiene and acrolein were quantum chemically studied using density functional theory in combination with coupled-cluster theory. (Thio)ureas render the studied Diels-Alder cycloaddition reactions exo selective and...

Although several studies have demonstrated that the male gender represents an independent risk factor for renal disease, evidence shows that androgens exert renal protective actions. The findings are controversial and no studies have evaluated the effects of orchiectomy and...

Inhibition of cadmium uptake by wheat with urease-producing bacteria combined with sheep manure under field conditions.

Chemosphere

Han H, Wu X, Bolan N, Kirkham MB, Yang J, Chen Z.
PMID: 34999099
Chemosphere. 2022 Jan 06;293:133534. doi: 10.1016/j.chemosphere.2022.133534. Epub 2022 Jan 06.

In heavy metal-contaminated farmland, microorganisms or organic fertilizers can be used to minimize heavy metal uptake by crops to ensure food safety. However, the mechanisms by which urease-producing and metal-immobilizing bacteria combined with manure inhibit Cd uptake in wheat...

Pruritus: Diagnosis and Management.

American family physician

Rupert J, Honeycutt JD.
PMID: 35029946
Am Fam Physician. 2022 Jan 01;105(1):55-64.

Pruritus is the sensation of itching; it can be caused by dermatologic and systemic conditions. An exposure history may reveal symptom triggers. A thorough skin examination, including visualization of the finger webs, anogenital region, nails, and scalp, is essential....

IMPORTANCE: Although kidney dysfunction and abnormalities in serum electrolyte levels are associated with poor clinical outcomes in patients with heart failure with preserved ejection fraction (HFpEF), the association of visit-to-visit variability in such laboratory measures with long-term outcomes is...

Mechanism of a double-channel nitrogen-doped lignin-based carbon on the highly selective removal of tetracycline from water.

Bioresource technology
