Fully hydrated! – Iron photocatalysis tests the waters.

Benzoate anions coordinate to cerium ions. Excitation of such complexes by light leads homolytic oxygen-cerium bond cleavage through ligand-to-metal charge transfer (LMCT). This process results in the reduction metal ion and oxidation ligand via a single-electron event. The resulting benzoic acid radical can serve as potent hydro-gen atom abstractor, facilitating activation carbon atoms C-H activation. study investigated scope other oxo-anions ligands on cerium(IV) ions that undergo...

We report pyridine N-oxides as neutral ligands in cerium photocatalysis. By using those ligands, photoactive Ce(IV)-species are generated, that show an extensive bathochromic shift compared to previously employed cerium-based complexes. This allows the effective utilization of green light redox-neutral CH-hydrazination small molecules under very mild photocatalytic conditions.

Children with chronic kidney disease (CKD) are subject to physical and psychosocial challenges, which may confer greater risk of developing psychiatric disorders. We sought examine key diagnoses in children CKD compared those the general pediatric population assess correlation between parent-reported diagnosis self-reported symptoms depression.Cross-sectional.Children ages 2-17 years receiving current medical care who participated Chronic Kidney Disease Study (CKiD) or National Survey...

We have developed a cerium-photocatalyzed aerobic oxidation of primary and secondary benzylic alcohols to aldehydes ketones using inexpensive CeCl 3 ·7H 2 O as photocatalyst air oxygen the terminal oxidant.

Functionalisation of partially water-soluble C-H precursors through Fe(III)Cl3 Ligand-to-Metal charge transfer catalysis in aqueous solution is achieved under near UV-light irradiation. The light-driven bond-homolysis the Fe-Cl bond within iron complex results generation highly reactive chlorine radicals, facilitating hydrogen atom abstraction from a furane-derived starting material. Sugars or cinchonidine derivatives promote interaction between metal salt and organic substrates. Lowering...

The issue of work-related sleep loss and consequent fatigue in medical residents continues to cause concern. Some, but not all, studies point postcall deficits performance. In this prospective study 34 pediatric residents, performance was compared during a heavy call rotation (defined as every fourth or fifth night) with light call, combined blood alcohol concentration 0.04 gm% 0.05 per 100 mL, placebo. group included 18 women 16 men mean age 29 years who worked at an academic center. An...

For diagnosis of incontinence the exact analysis dynamics micturition is great importance, primarily in order to evaluate urethral flow-resistance and detrusor activity. Extending already existing methods for evaluation urodynamics, we developed a complex method cine/pressure/flow/cystourethrography. All data were recorded simultaneously stored on videotape. Especially cases with neurogenic component important information causative therapy was gained using this investigation. Thus 20...

In this paper, a modified carrier sense multiple access-collision avoidance (CSMA-CA) mechanism, termed as quiet period-CSMA-CA (QP-CSMA-CA) is proposed, for the purposes of coexistence in cognitive networking set-up with secondary clients that seek access using 802.11. work to date, dedicated periods have been defined purpose, synchronized duration wherein all are prohibited from uplink transmissions; interval intended sensing channel status so detect out-of-network transmissions. However,...

Abstract We report the photocatalytic functionalization of terminal alkenes to vicinal dichlorides by using visible light and FeCl3 as a catalyst, LiCl chloride source, air an oxidant. The transformation is proposed be initiated ligand-to-metal charge-transfer bond homolysis Fe–Cl bond, giving highly reactive radical able initiate olefins. process shows high chemoselectivity broad functional-group tolerance with yields up 94% under mild conditions.

Abstract We report the O‐alkylation of oximes with Michael acceptors using Cs 2 CO 3 as catalyst. The transformation proceeds stereospecifically retention oxime configuration. Irradiation visible light in presence diphenyl anthracene and cerium complexes affects E to Z configuration ratio ether products, but a complete stereocontrol was not achieved. operationally simple protocol allows synthesis various O‐alkylated products that are useful precursors for further chemical transformations.

A 12-year-old boy presented with 3 weeks of calf pain, tripping, and progressive inability to walk. The onset was preceded by a sore throat 4 prior, but no recent immunizations sick contacts. He began having problems "catching his toes" for 2 weeks. had visual complaints bowel or bladder incontinence. travel there were heavy metal solvent exposures. prior medical history he on prescription medications. Developmentally, track just successfully completed fifth grade. However, reported be...
