Shortening procedures

Capillary GC was used to obtain high resolution profiles of 27 organic acids, caffeine, and sucrose in dimethylsulphoxide extracts of roast and ground coffees in a 60-min analysis.26 A shortened procedure is also reported for quantitative detection of 5-caffeoylquinic (5-CQA) and quinic (QA) acids and sucrose ng detection limits were achieved. Major commer-... 

If one is interested in only approximate values of the orbit energies of the TT HOMOs, a reduced procedure may be used based on the truncated secular Equation 104. This shortened procedure reproduces the tt HOMO orbital energies within 0.3 eV. 

An alternative to the processing steps listed in Subheading 3.4. can be used. For most markers that are routinely assayed, this shortened procedure works well and requires much less effort. After pretreatment and hybridization as described above, process the samples as follows ... 

Over the last two decades, the use of eukaryotic cells for expression of recombinant proteins has become the preferred choice for many applications. This is primarily the case when posttranslational modifications and correct disulfide-bond formation are necessary for protein folding and activity. Among the eukaryotic expression systems, the baculovirus-infected insect cell platform has gained particular attention, resulting in the development and implementation of multiple strategies for protein expression. Here, we present baculovirus-infected insect cells as an efficient expression system for eukaryotic proteins. We demonstrate a simplified and a shortened procedure for recombinant virus production that is sufficient for large-scale production of proteins in insect cells. 

In fact, any therapeutic intervention for Peyronie s disease may have some adverse impact upon erectile function documentation of the baseline erectile function is therefore imperative, from both the medical and the medico-legal perspective. Moreover, in patients with normal erection, either shortening or lengthening procedures can be undertaken, whereas in patients with coexistent erectile dysfunction shortening procedures or prosthesis implantation should be considered the treatment of choice (Ahmed et al. 1998 Hakim 2002). 

In patients with corporeal plication ultrasonography shows small lumps next to the albugineal sutures extending within the corpora cavernosa (Bertolotto et al. 2005). In patients with normal erection before surgery after shortening procedures, postoperative erectile dysfunction is uncommon. When present, color Doppler interrogation allows evaluation of the penile arteries and identification of leakage pathways. 

The facile conversion of C-nitromethyl- into aldehydo-groups with aqueous titanium (III) chloride has provided a convenient route to several C-formyl sugars, which can be isomerized to the thermodynamically favoured isomers with methan-olic sodium methoxide (Scheme 70). Conventional reactions have been used to obtain the 3-C-acetamidomethyl-3-deoxy-D-ribofuranose derivative (388) from l,2-0-isopropylidene-5-0-trityl-a-D-er> thro-pentofuranos-3-ulose, and the 6-benzoate (389) of 3-deoxy-l,2-0-isopropylidene-3-C-nitromethyl-a-D-allo-furanose has been converted, by a conventional chain-shortening procedure, into... 

Jung and co-workers [95] have quoted a shortened procedure with only a single TLC stage on silica gel, using benzene-ether (40 + 60) and Kober-reaction on the eluates. 

Reduction of the 3-C-cyano 3-sulphonate derivative (118) with lithium aluminium hydride furnished the branched-chain sugar (119) and the spiro-epimine (120), which, on further reduction and 7V-acetylation, gave 3-acetamido-3-deoxy-l,2 5,6-di-(7-isopropylidene-3-C-methyl-a-D-glucofuranose. The latter branched-chain amino-sugar was also converted into related o-xylofuranose derivatives by a conventional chain-shortening procedure, following removal of the 5,6-0-isopropylidene group.
