Spinal anaesthesia for elective surgery: A comparison of hyperbaric solution of racemic
bupivacaine, levobupivacaine and ropivacaine.
Extradural S(-)bupivacaine: comparison with racemic
MAC] in dogs premedicated with an acepromazine-morphine combination followed by a single intramuscular dose of racemic
or S(+)-ketamine administered after anesthetic induction with propofol.
S(+) carvone, R(-) carvone and racemic
carvone were all separated on an [UPC.
Pasteur hypothesized that the optical activity of tartaric acid was related to its asymmetry, which prompted him to think that racemic
acid lacked optical activity because its asymmetric crystals were equal but opposite, thereby canceling one another's light-rotating effects.
The inventor and earlier developers of laetrile unambiguously warned the NCI of what it already knew: racemic
laetrile was subpotent.
Inhalations of racemic
adrenaline worked no better than inhalations of saline in infants admitted to Norwegian hospitals.
Levobupivacaine, the pure S(-)-enantiomer of racemic
bupivacaine, has recently been introduced for routine obstetric and nonobstetric spinal and epidural anaesthesia, peripheral nerve blocks, and infiltration analgesia.
India, May 8 -- Thermo Fisher Scientific has launched new Maybridge Chiral Resolution Screening and Purification Kits to give organic chemists simple and rapid access to optically pure chiral compounds from their racemic
or L-epinephrine reduces severity of symptoms in moderate-to-severe croup (SOR: C, limited-quality disease-oriented evidence).
NatureWorks notes that compared with racemic
lactide's melting point of nearly 130[degrees]C, and L- and D-lactide's 97[degrees]C, Ingeo M700's melting point is below 60[degrees]C.
baclofen (mixture of arbaclofen and esbaclofen) is approved by the FDA to treat spasticity and stiff muscles due to cerebral palsy or other forms of brain or spinal cord injury, but arbaclofen, the more active form of baclofen, is not FDA approved.
