Exploring the Scope of Asymmetric Synthesis of β-Hydroxy-γ-lactams via Noyori-type Reductions.

Organic letters

Lynch D, Deasy RE, Clarke LA, Slattery CN, Khandavilli UB, Lawrence SE, Maguire AR, Magnus NA, Moynihan HA.
PMID: 27656907
Org Lett. 2016 Oct 07;18(19):4978-4981. doi: 10.1021/acs.orglett.6b02416. Epub 2016 Sep 22.

Enantio- and diastereoselective hydrogenation of β-keto-γ-lactams with a ruthenium-BINAP catalyst, involving dynamic kinetic resolution, has been employed to provide a general, asymmetric approach to β-hydroxy-γ-lactams, a structural motif common to several bioactive compounds. Full conversion to the desired β-hydroxy-γ-lactams...

Reversible quantum brownian heat engines for electrons.

Physical review letters

Humphrey TE, Newbury R, Taylor RP, Linke H.
PMID: 12225160
Phys Rev Lett. 2002 Sep 09;89(11):116801. doi: 10.1103/PhysRevLett.89.116801. Epub 2002 Aug 22.

Brownian heat engines use local temperature gradients in asymmetric potentials to move particles against an external force. The energy efficiency of such machines is generally limited by irreversible heat flow carried by particles that make contact with different heat...

Experience with sentinel node localisation in a district general hospital breast unit.

Breast (Edinburgh, Scotland)

Walker PM, Hussain M, Humphrey CS.
PMID: 14965692
Breast. 2002 Aug;11(4):343-5. doi: 10.1054/brst.2002.0446.

Intraoperative lymphatic mapping with identification of the first draining lymph node (sentinel node) is under investigation as a possible sole axillary staging procedure in breast cancer patients. The role of sentinel node biopsy in the district general hospital breast...

Growth and morphological responses to different UV wavebands in cucumber (Cucumis sativum) and other dicotyledonous seedlings.

Physiologia plantarum

Shinkle JR, Atkins AK, Humphrey EE, Rodgers CW, Wheeler SL, Barnes PW.
PMID: 15032858
Physiol Plant. 2004 Feb;120(2):240-248. doi: 10.1111/j.0031-9317.2004.0237.x.

We examined the influence of short-term exposure of different UV wavebands on the fine-scale kinetics of hypocotyl growth of dim red light-grown cucumbers (Cucumis sativus L.) and other selected dicotyledonous seedlings to evaluate: (1) whether responses induced by UV-B...

Spectrophotometric determination of cyanide with organic disulphides.

Talanta

Humphrey RE, Hinze W.
PMID: 18960910
Talanta. 1971 May;18(5):491-7. doi: 10.1016/0039-9140(71)80077-2.

The reaction of cyanide ion with the disulphides 2,2'-dithiodipyridine, 4,4'-dithiodipyridine, 2,2'-dithiodipyrimidine, and 5,5'-dithiobis(2-nitrobenzoic acid) to displace an absorbing thiol anion has been evaluated for the spectrophotometric determination of cyanide. Reaction is somewhat slow and is applicable to cyanide determination...

The dopaminergic system in the aging brain of Drosophila.

Frontiers in neuroscience

White KE, Humphrey DM, Hirth F.
PMID: 21165178
Front Neurosci. 2010 Dec 08;4:205. doi: 10.3389/fnins.2010.00205. eCollection 2010.

Drosophila models of Parkinson's disease are characterized by two principal phenotypes: the specific loss of dopaminergic (DA) neurons in the aging brain and defects in motor behavior. However, an age-related analysis of these baseline parameters in wildtype Drosophila is...

The HCH-1 model of enzymatic cellulose hydrolysis.

Biotechnology and bioengineering

Holtzapple MT, Caram HS, Humphrey AE.
PMID: 18553446
Biotechnol Bioeng. 1984 Jul;26(7):775-80. doi: 10.1002/bit.260260723.

Solka Floc BW200 was enzymatically hydrolyzed in a batch reactor using a commercial cellulase preparation. A total of 50 different hydrolysis conditions were run within a 10-fold range in enzyme concentration and a 30-fold range in cellulose concentration. The...

Estimation of fermentation biomass concentration by measuring culture fluorescence.

Applied and environmental microbiology

Zabriskie DW, Humphrey AE.
PMID: 16345274
Appl Environ Microbiol. 1978 Feb;35(2):337-43. doi: 10.1128/aem.35.2.337-343.1978.

The fluorescence of a fermentation culture was studied for its application as an estimator of biomass concentration. The measurement was obtained by irradiating the culture with ultraviolet light (366 nm) through a glass window and detecting fluorescent light at...
