The Effect of Organic-cr Dietary Supplementation on Stress Response in Transport-stressed Beef Cattle
Transportation over long distances resulted in stress at animal. Under these circumstances, animalusually manifest depression and the impact on physiological condition changes and loss of body weight.The objectives of the research were to examine effect supplementation of organic-Cr type into diets intransport-stress beef cattle on physiological condition, haematochemical (included were haematologicalcondition and blood chemical) and body weight changes. The experiment was conducted using 16 beefcattle those were transported by truck for a distance of 400 km from Malangbong to Tangerang. Theexperiment was arranged by Completely Randomized Design with four treatments and four replications.The dietary treatments consisted of R0 (basal diet without Cr supplemented), R1 (R0+3ppm organic-Crresulted of alkali hydrolysis), R2 (R0+3 ppm organic-Cr resulted from bioprocess), R3 (R0+3 ppmorganic-Cr resulted from bioremediation). The result indicated that type of organic-Cr supplementationat 3 ppm in diet did not influence physiological condition, haematochemical and body weight at beefcattle transported for seven hours. There was indication that beef cattle fed on control diet (without Cr)showed a stress symptom, their loss of body weight were higher (5.41%) compared to beef given dietcontains organic-Cr (3.72%, 5.04% and 4.83%, respectively for R1, R2 and R3)
Enantioselective Desymmetrization of Bicyclic Hydrazines using a <i>C</i><sub>2</sub>‑Symmetric N‑Heterocyclic Carbene (NHC) Palladium Complex as Catalyst
The
first example of palladium-catalyzed enantioselective desymmetrization
of 2,3-bicyclic hydrazines with arylboronic acids through a ring-opening
process is described by using a chiral <i>C</i><sub>2</sub>-symmetric N-heterocyclic carbene (NHC) palladium complex as the
catalyst. The reaction can be performed under convenient conditions
to give <i>trans</i>-1,2-disubstituted 3-cyclopentenes <b>3</b> with high regioselectivity in good to excellent yields (up
to 95%) and moderate to good enantioselectivities (up to 88% ee)
Enantioselective Synthesis of Polycyclic Indole Derivatives Based on aza-Morita–Baylis–Hillman Reaction
A chiral phosphine-catalyzed asymmetric
aza-Morita–Baylis–Hillman
reaction between indole-derived sulfonyl imines and bisÂ(3-chlorophenyl)Âmethyl
acrylate has been developed, giving the desired adducts in good yields
and enantiomeric excess values along with the further transformations
to polycyclic indoles such as dihydropyridoÂ[1,2-<i>a</i>]Âindole and dihydropyrazinoÂ[1,2-<i>a</i>]Âindole skeleton
