International journal of cancer, Volume 136, Issue 6, 8 2 2014, Pages 1434-1444 Sorafenib synergizes with metformin in NSCLC through AMPK pathway activation. Groenendijk FH, Mellema WW, van der Burg E, Schut E, Hauptmann M, Horlings HM, Willems SM, van den Heuvel MM, Jonkers J, Smit EF, Bernards R

The multikinase inhibitor sorafenib is under clinical investigation for the treatment of many solid tumors, but in most cases, the molecular target responsible for the clinical effect is unknown. Furthermore, enhancing the effectiveness of sorafenib using combination strategies is a major clinical challenge. Here, we identify sorafenib as an activator of AMP-activated protein kinase (AMPK), in a manner that involves either upstream LKB1 or CAMKK2. We further show in a phase II clinical trial in...

American heart journal, Volume 168, Issue 5, 7 1 2014, Pages 682-689 Effect of alirocumab, a monoclonal antibody to PCSK9, on long-term cardiovascular outcomes following acute coronary syndromes: rationale and design of the ODYSSEY outcomes trial. Schwartz GG, Bessac L, Berdan LG, Bhatt DL, Bittner V, Diaz R, Goodman SG, Hanotin C, Harrington RA, Jukema JW, Mahaffey KW, Moryusef A, Pordy R, Roe MT, Rorick T, Sasiela WJ, Shirodaria C, Szarek M, Tamby JF, Tricoci P, White H, Zeiher A, Steg PG

Background: Following acute coronary syndrome (ACS), the risk for future cardiovascular events is high and is related to levels of low-density lipoprotein cholesterol (LDL-C) even within the setting of intensive statin treatment. Proprotein convertase subtilisin/kexin type 9 (PCSK9) regulates LDL receptor expression and circulating levels of LDL-C. Antibodies to PCSK9 can produce substantial and sustained reductions of LDL-C. The ODYSSEY Outcomes trial tests the hypothesis that treatment with al... Abstract

Our closest nonhuman primate relatives, chimpanzees, engage in potentially lethal between-group conflict; this collective aggressive behavior shows parallels with human warfare. In some communities, chimpanzee males also severely attack and even kill females of the neighboring groups. This is surprising given their system of resource defense polygyny, where males are expected to acquire potential mates. We develop a simple mathematical model based on reproductive skew among primate males to solv... Abstract

International journal of cardiology, Volume 176, Issue 3, 3 1 2014, Pages 788-793 RP105 deficiency aggravates cardiac dysfunction after myocardial infarction in mice. Louwe MC, Karper JC, de Vries MR, Nossent AY, Bastiaansen AJ, van der Hoorn JW, Willems van Dijk K, Rensen PC, Steendijk P, Smit JW, Quax PH

Background: Toll-like receptor-4 (TLR4), a receptor of the innate immune system, is suggested to have detrimental effects on cardiac function after myocardial infarction (MI). RP105 (CD180) is a TLR4 homolog lacking the intracellular signaling domain that competitively inhibits TLR4-signaling. Thus, we hypothesized that RP105 deficiency, by amplifying TLR4 signaling, would lead to aggravated cardiac dysfunction after MI. Methods and results: First, whole blood from RP105-/- and wild-type (WT) ma... Abstract

Preventive veterinary medicine, Volume 117, Issue 2, 2 1 2014, Pages 375-387 A multidisciplinary approach to determine factors associated with calf rearing practices and calf mortality in dairy herds. Santman-Berends IM, Buddiger M, Smolenaars AJ, Steuten CD, Roos CA, Van Erp AJ, Van Schaik G

In the Netherlands, an increase in ear-tagged calf mortality (3 days to 1 year of age) in dairy farms was observed. The aim was to determine why calf mortality increased and how to reduce calf mortality in herds with structural high rates. A multi-disciplinary approach was chosen to study this phenomenon. First analysis of census data revealed that the majority of the calves died in the first month of life. In addition, a panel of 236 farmers indicated that the increase in calf mortality might b...

Der Urologe. Ausg. A, Volume 53, Issue 8, 1 1 2014, Pages 1136-1145 [The demographic development in Germany : challenge and chances for urology]. Schneider AW, Fichtner J

Urology is affected by the demographic development in Germany more than any other medical discipline. Despite a relatively stable total population, by the year 2040 there will be an absolute and relevant increase in urological diseases caused only by the demographic development in the population. This is particularly true for the increase in oncological treatment just in the field of the discipline of urology. Even now the current numbers for tumor development in Germany (RKI 2014) in the urolog... Abstract

Circulation research, Volume 115, Issue 8, 1 1 2014, Pages 696-708 Inhibition of 14q32 MicroRNAs miR-329, miR-487b, miR-494, and miR-495 increases neovascularization and blood flow recovery after ischemia. Welten SM, Bastiaansen AJ, de Jong RC, de Vries MR, Peters EA, Boonstra MC, Sheikh SP, La Monica N, Kandimalla ER, Quax PH, Nossent AY

Rationale: Effective neovascularization is crucial for recovery after cardiovascular events. Objective: Because microRNAs regulate expression of up to several hundred target genes, we set out to identify microRNAs that target genes in all pathways of the multifactorial neovascularization process. Using www.targetscan.org, we performed a reverse target prediction analysis on a set of 197 genes involved in neovascularization. We found enrichment of binding sites for 27 microRNAs in a single microR... Abstract

Perfusion, Volume 30, Issue 4, 1 1 2014, Pages 295-301 Sevoflurane-enriched blood cardioplegia: the intramyocardial delivery of a volatile anesthetic. van der Baan A, Kortekaas KA, van Es E, Meier S, Klautz RJ, Engbers FH

Myocardial ischemia/reperfusion injury is a major problem in cardiac surgery, characterized by an enhanced inflammatory response postoperatively. Sevoflurane has anti-inflammatory effects and may attenuate this injury. This study describes a novel approach to using sevoflurane as a local anti-inflammatory drug and not as an anesthetic. Therefore, a pediatric oxygenator with a sevoflurane vaporizer was integrated into the blood cardioplegia system of an adult bypass system. In addition, a gas ble... Abstract

Proceedings. Biological sciences, Volume 281, Issue 1788, 1 1 2014, Pages 20140263 Language evolution: syntax before phonology? Collier K, Bickel B, van Schaik CP, Manser MB, Townsend SW

Phonology and syntax represent two layers of sound combination central to language's expressive power. Comparative animal studies represent one approach to understand the origins of these combinatorial layers. Traditionally, phonology, where meaningless sounds form words, has been considered a simpler combination than syntax, and thus should be more common in animals. A linguistically informed review of animal call sequences demonstrates that phonology in animal vocal systems is rare, where... Abstract
