I examined the evolutionary factors maintaining two environmentally induced morphs in ponds of variable duration. Larvae of New Mexico spadefoot toads (Scaphiopus multiplicatus) often occur in the same pond as a large, rapidly developing carnivorous morph and as a...

Olanzapine in the treatment of depression with psychotic features: A prospective open-label study.

International journal of psychiatry in clinical practice

Adli M, Wiethoff K, Baethge C, Pfennig A, Stamm T, Bauer M.
PMID: 24931659
Int J Psychiatry Clin Pract. 2008;12(3):202-9. doi: 10.1080/13651500801911144.

Objective. Depression with psychotic features is a severe subtype of major depression associated with the presence of delusions, hallucinations and specific neurobiological features. Despite clinical consensus and guideline recommendations, data comparing the efficacy of combining antipsychotics with antidepressants compared...

Prophylactic lithium treatment and cognitive performance in patients with a long history of bipolar illness: no simple answers in complex disease-treatment interplay.

International journal of bipolar disorders

Pfennig A, Alda M, Young T, MacQueen G, Rybakowski J, Suwalska A, Simhandl C, König B, Hajek T, O'Donovan C, Wittekind D, von Quillfeldt S, Ploch J, Sauer C, Bauer M.

Cognitive impairment in patients with bipolar disorder (BD) is not restricted to symptomatic phases. It is also present in euthymia. There is evidence of differences in the brain's structure between bipolar patients and healthy individuals, as well as changes...

A comparative study of the optical characteristics of intact cells of photosynthetic green sulfur bacteria containing bacteriochlorophyll c, d or e.

This year, the CUSO Summer School in Organic Chemistry celebrated its 40th anniversary. With a coinciding 450th anniversary, it was organized by the University of Geneva. The focus was on large molecules and supramolecules that are synthesized from scratch,...

Moderate intensity physical activity prevents increased blood glucose concentrations, fat pad deposition and cardiac action potential prolongation following diet-induced obesity in a juvenile-adolescent rat model.

BMC obesity

van Waveren A, Duncan MJ, Coulson FR, Fenning A.
PMID: 26217503
BMC Obes. 2014 Aug 20;1:11. doi: 10.1186/2052-9538-1-11. eCollection 2014.

BACKGROUND: Both obesity and a lack of physical activity have been associated with an elevated risk of cardiovascular disease (CVD). The incidence of obesity is increasing, especially in juvenile-adolescents. While there is limited research examining the chronic effects of...

Excited-state electronic coupling and photoinduced multiple electron transfer in two related ligand-bridged hexanuclear mixed-valence compounds.

Inorganic chemistry

Pfennig BW, Mordas CJ, McCloskey A, Lockard JV, Salmon PM, Cohen JL, Watson DF, Bocarsly AB.
PMID: 12184755
Inorg Chem. 2002 Aug 26;41(17):4389-95. doi: 10.1021/ic020232u.

The synthesis, characterization, electrochemical, photophysical, and photochemical properties of two hexanuclear mixed-valence compounds are reported. Each supramolecular species consists of two cyano-bridged [(NC)(5)Fe(II)-CN-Pt(IV)(NH(3))(3)L-NC-Fe(II)(CN)(5)] triads that are linked to each other through a Pt(IV)-L-Pt(IV) bridge, where L = 4,4'-dipyridyl (bpy)...

Genetic details, optimization and phage life histories.

Trends in ecology & evolution

Trends Ecol Evol. 2004 Feb;19(2):76-82. doi: 10.1016/j.tree.2003.10.008.

Optimality models assume that phenotypes evolve by natural selection largely independently of underlying genetic mechanisms. This neglect of genetic mechanisms is considered an advantage by some evolutionary biologists but a fatal flaw by others. The controversy has gone unresolved,...

Schizophrenia risk and paternal age: a potential role for de novo mutations in schizophrenia vulnerability genes.

CNS spectrums

Malaspina D, Brown A, Goetz D, Alia-Klein N, Harkavy-Friedman J, Harlap S, Fennig S.

CNS Spectr. 2002 Jan;7(1):26-9. doi: 10.1017/s1092852900022239.

How schizophrenia (SZ) is maintained at roughly 1% of the population despite diminished reproduction is one puzzle currently facing researchers. De novo mutations were first proposed over half a century ago as a source for new SZ genes. Current...
