Attracting Enantiomers: Chiral Analytes That Are Simultaneously Shift Reagents Allow Rapid Screening of Enantiomeric Ratios by NMR Spectroscopy.

Chemistry (Weinheim an der Bergstrasse, Germany)

Storch G, Haas M, Trapp O.
PMID: 28317203
Chemistry. 2017 Apr 24;23(23):5414-5418. doi: 10.1002/chem.201700461. Epub 2017 Apr 03.

The rapid and direct determination of enantiomeric ratios is of increasing interest due to the significantly reduced effort compared to chromatographic methods and the large number of analytes, for instance in enantioselective catalysis. Current strategies include colorimetric assays, (a)chiral...

Med Mycol Case Rep. 2012 May 27;1(1):35-8. doi: 10.1016/j.mmcr.2012.05.003. eCollection 2012.

Graphium basitruncatum is genetically and morphologically distinct from other Graphium and Scedosporium species, and has been reported only once previously as a cause of human disease. We report a case of Graphium basitruncatum fungemia in a two year old...

Early childhood trichotillomania: Initial considerations on phenomenology, treatment, and future directions.

Infant mental health journal

Park JM, Rahman O, Murphy TK, Storch EA.
PMID: 28520100
Infant Ment Health J. 2012 Mar;33(2):163-172. doi: 10.1002/imhj.21317. Epub 2012 Feb 23.

Historically, trichotillomania (TTM) in young children (0-3 years old) generally has been considered to be a benign habit that is clinically distinct from the TTM seen in older children and adults. However, early childhood TTM can be an impairing...

Predicting potential distribution of poorly known species with small database: the case of four-horned antelope Tetracerus quadricornis on the Indian subcontinent.

Ecology and evolution

Pokharel KP, Ludwig T, Storch I.
PMID: 27069584
Ecol Evol. 2016 Mar 04;6(8):2297-307. doi: 10.1002/ece3.2037. eCollection 2016 Apr.

Information gaps on the distribution of data deficient and rare species such as four-horned antelope (FHA) in Nepal may impair their conservation. We aimed to empirically predict the distribution of FHA in Nepal with the help of data from...

Tautomerization-mediated molecular switching between six- and seven-membered rings stabilized by hydrogen bonding.

Chemistry (Weinheim an der Bergstrasse, Germany)

Storch G, Spallek MJ, Rominger F, Trapp O.
PMID: 25940593
Chemistry. 2015 Jun 08;21(24):8939-45. doi: 10.1002/chem.201500524. Epub 2015 May 04.

1,3,4,6-Tetraketones typically undergo keto-enol tautomerism forming bis-enols stabilized by intramolecular hydrogen bonding in two six-membered rings. However, 1,3,4,6-tetraketones derived from the terpene ketone camphor and norcamphor exist as isomers with two distinguishable modes of intramolecular hydrogen bonding, namely, the...

A "clearcut" case? Brown bear selection of coarse woody debris and carpenter ants on clearcuts.

Forest ecology and management

Frank SC, Steyaert SM, Swenson JE, Storch I, Kindberg J, Barck H, Zedrosser A.
PMID: 26190890
For Ecol Manage. 2015 Jul 15;348:164-173. doi: 10.1016/j.foreco.2015.03.051.

Forest management alters habitat characteristics, resulting in various effects among and within species. It is crucial to understand how habitat alteration through forest management (e.g. clearcutting) affects animal populations, particularly with unknown future conditions (e.g. climate change). In Sweden,...

Advances in the treatment of pediatric obsessive-compulsive d-cycloserine with exposure and response prevention.

Neuropsychiatry (London). 2012 Aug;2(4). doi: 10.2217/npy.12.38.

Exposure-based cognitive-behavioral therapy and serotonin reuptake inhibitor medications are efficacious treatment options for the management of pediatric obsessive-compulsive disorder. Despite established efficacy, many youths receiving either therapy remain symptomatic after acute treatment. Regardless of the rationale for persistent symptoms,...
