Recent strides towards greater sustainability in materials and energy production have led to a resurgence the study utilization of carbohydrates. Opposite C6 C5 carbohydrates, C4 carbohydrates (tetroses) are much less accessible from biological sources. A promising approach for is cracking C2 fragments, subsequent combination two fragments tetroses. Here, we show that suitable choice reaction c...

Components of innate immunity have recently been implicated in the regulation of developmental processes. Most strikingly, complement factors appear to be involved in limb regeneration in certain urodele species. Prompted by these observations and anticipating a conserved role of complement in mammalian regeneration, we have now investigated the involvement of complement component C5 in liver r...

1,5-Bis(4-hydroxy-3-methoxyphenyl)-1,4-pentadiene-3-one (2) was isolated from Curcuma domestica as a curcumin (1)-related compound, which we named C5-curcumin. Intrigued by the potent antitumor activity of C5-curcumin (2)-related 1,5-bisaryl-1,4-pentadiene-3-ones [bis(arylmethylidene)acetones, termed C5-curcuminoids], we previously conducted a structure-activity relationship study of C5-curcumi...

The highly ordered mesoporous Co3O4-Al2O3 bimetal oxide, prepared by a nano-casting method, was modified with Sn promoter (denoted as Sn/m-CoAlOx) to enhance selectivity liquid-hydrocarbons well suppress CO2 formation formed water gas-shift (WGS) reaction activity during CO hydrogenation hydrocarbons (Fischer–Tropsch Synthesis (FTS) reaction). Based on the surface properties of Sn/m-CoAlOx in r...

OBJECTIVE Measurement of plasma C2 glucose enrichment is cumbersome. Therefore, the plasma C5 glucose-to-(2)H(2)O rather than the plasma C5-to-C2 glucose ratio commonly has been used to measure gluconeogenesis and glycogenolysis during hyperinsulinemic-euglycemic clamps. The validity of this approach is unknown. RESEARCH DESIGN AND METHODS Ten nondiabetic and 10 diabetic subjects ingested (2)...

BACKGROUND It has been reported that C5 palsy is a potential complication of both anterior and posterior cervical spine surgery, although several mechanisms of C5 palsy following posterior cervical surgery have been proposed, few reports about correlative risk factors have been elaborated on C5 palsy after anterior cervical decompression and fusion (ACDF). OBJECTIVE The purpose of this study ...

The hydroformylation of alkenes is a major commercial process used for the production of oxygenated organic compounds. Commercial hydroformylation processes may produce significant quantities of waste material. When the hydroformylation reaction is performed using a homogeneous catalyst, an organic or aqueous solvent is employed and a significant effort must be expended to recover the catalyst ...

A new 3D, spin-state-selective coherence transfer NMR experiment is described that yields accurate measurements for eight scalar or dipolar couplings within a spin system composed of a methylene adjacent to a methine group. Implementations of the experiment have been optimized for proteins and for nucleic acids. The experiments are demonstrated for Cbeta-Calpha moieties of the third IgG-binding...
