Monocryl has a low tissue reactivity, maintains high tensile strength, and has a half-life of 7 to 14 days. At 1 week, its in vivo tensile strength is at 50–60% undyed (60–70% dyed), 20–30% undyed (30–40% dyed) at two weeks, and essentially completely hydrolyzed by 91–119 days. [ 3 ]
Maintains strength for 10–14 days [2] 84% at 2 weeks, 23% at 4 weeks [2] 80% at 2 weeks, 44% at 8 weeks. Complete absorption within 200 days [2] Structure: Multifilament: Multifilament: Braided: Monofilament Origin: Bovine serosa surface finish. Made by twisting together strands of purified collagen taken from the small intestine of healthy ...
The manufacturing techniques, derived at the beginning from the production of musical strings, did not allow thinner diameters. As the procedures improved, #0 was added to the suture diameters, and later, thinner and thinner threads were manufactured, which were identified as #00 (#2-0 or #2/0) to #000000 (#6-0 or #6/0).

2,3-pyridinedicarboxylic acid 2,4-pyridinedicarboxylic acid 2,5-pyridinedicarboxylic acid 2,6-pyridinedicarboxylic acid 3,4-pyridinedicarboxylic acid 3,5-pyridinedicarboxylic acid Structural formula: CAS registry number: 89-00-9 499-80-9 100-26-5 499-83-2 490-11-9 499-81-0
The acidity of the methylene group in diphenylmethane is due to the weakness of the (C 6 H 5) 2 CH–H bond, which has a bond dissociation energy of 82 kcal mol −1 (340 kJ mol −1). [5] This is well below the published bond dissociation energies for comparable C–H bonds in propane , where BDE((CH 3 ) 2 CH–H)=98.6 kcal mol −1 , and ...
The 3 substrates of this enzyme are succinyl-CoA, (S)-2,3,4,5-tetrahydropyridine-2,6-dicarboxylate, and H 2 O, whereas its two products are CoA and N-succinyl-L-2-amino-6-oxoheptanedioate. This enzyme belongs to the family of transferases, specifically those acyltransferases transferring groups other than aminoacyl groups. The systematic name ...
2,6-DMP is produced by the methylation of phenol. With production >100,000 tons/y, it is the most important xylenol. The methylation is carried out by contacting gaseous phenol and methanol at elevated temperatures in the presence of a solid acid catalyst: [2] [3] C 6 H 5 OH + 2 CH 3 OH → (CH 3) 2 C 6 H 3 OH + 2 H 2 O
Syringol is the organic compound with the formula HO(CH 3 O) 2 C 6 H 3. The molecule is a phenol, with methoxy groups in the flanking (2 and 6) positions. It is the symmetrically dimethylated derivative of pyrogallol. It is a colorless solid, although typical samples are brown owing to air-oxidized impurities.
