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).

The simplest case refers to the formation of a strictly linear polymer by the reaction (usually by condensation) of two monomers in equimolar quantities. An example is the synthesis of nylon-6,6 whose formula is [−NH−(CH 2) 6 −NH−CO−(CH 2) 4 −CO−] n from one mole of hexamethylenediamine, H 2 N(CH 2) 6 NH 2, and one mole of adipic acid, HOOC−(CH 2) 4 −COOH.
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.
Poly(2,6-diphenylphenylene oxide) is used for trapping of volatiles and semi-volatiles from air such as environmental air and human breath, and for personal exposure monitoring. It is also used for determining the emission of chemical substances from plants, soil and commercial products.
The 2,6-dimethylpiperidines are prepared by reduction of 2,6-dimethylpyridine (2,6-lutidine). The achiral isomer is the predominant isomer produced in this reaction. The 2,6-dimethylpiperidines are of interest for their conformational properties. The (R,S)-isomer exists largely in the chair conformation with equatorial methyl groups.
vicryl sutures Lettering on Vicryl foil. Vicryl (polyglactin 910) is an absorbable, synthetic, usually braided suture, manufactured by Ethicon Inc., a subsidiary of Johnson and Johnson.
