Ethylene, a regulator of young fruit abscission.

Plant physiology

Lipe JA, Morgan PW.
PMID: 16658444
Plant Physiol. 1973 May;51(5):949-53. doi: 10.1104/pp.51.5.949.

In an earlier study we reported that detached cotton flowers produced sufficient ethylene before the period of natural abscission to suggest that ethylene might be a natural regulator of young fruit abscission. The present report explores this probability further....

Location of ethylene production in cotton flowers and dehiscing fruits.

Planta

Lipe JA, Morgan PW.
PMID: 24458822
Planta. 1973 Mar;115(1):93-6. doi: 10.1007/BF00388610.

Over half of the ethylene produced by 1-day-old cotton flowers came from the combined stigma, style, and stamens. These tissues produced 0.0050 μl/flower·h compared to 0.0024 and 0.0010 μl/flower·h produced by the petals and ovary, respectively. Walls of dehiscing...

Who participates in seasonal influenza vaccination? Past behavior moderates the prediction of adherence.

Advances in preventive medicine

Ernsting A, Lippke S, Schwarzer R, Schneider M.
PMID: 21991430
Adv Prev Med. 2011;2011:148934. doi: 10.4061/2011/148934. Epub 2011 Aug 23.

Background. Vaccination effectively prevents seasonal influenza. To promote vaccination adherence, it is necessary to understand the motivational process that underlies vaccination behavior. This was examined along with the moderating influence of past behavior on intention formation. Methods. German employees...

To determine the binding interactions and ability to form the non-covalent systems, the association process between 5,10,15,20-tetrakis[4-(trimethylammonio)phenyl]-21H,23H-porphine tetra-p-tosylate (H

Influence of Electromechanical Activity on Cardiac Differentiation of Mouse Embryonic Stem Cells.

Cardiovascular engineering and technology

Limpitikul W, Christoforou N, Thompson SA, Gearhart JD, Tung L, Lipke EA.
PMID: 29057018
Cardiovasc Eng Technol. 2010 Sep;1(3):179-193. doi: 10.1007/s13239-010-0020-8. Epub 2010 Aug 06.

During differentiation, mouse embryonic stem cell-derived cardiomyocytes (mESC-CMs) receive electromechanical cues from spontaneous beating. Therefore, promoting electromechanical activity via electrical pacing or suppressing it by drug treatment might affect the cellular functional development. Electrical pacing was applied to confluent...

Lessons Learned From a Randomized Controlled Trial of Short-Course Intravenous Antibiotic Therapy for Erysipelas and Cellulitis of the Lower Limb (Switch Trial).

Open forum infectious diseases

Clarke MC, Cheng AC, Pollard JG, Birch M, Cowan RU, Linke JA, Walton AL, Friedman ND.

Open Forum Infect Dis. 2019 Jul 20;6(9):ofz335. doi: 10.1093/ofid/ofz335. eCollection 2019 Sep.

BACKGROUND: The diagnosis of cellulitis is made clinically without a gold standard diagnostic test, and cellulitis has many disease mimics. There is currently no consensus for optimal antimicrobial treatment duration or method of antimicrobial delivery.METHODS: This was a randomized...

The Possible Antecedents and Consequences of Matching of Food Intake: Examining the Role of Trait Self-Esteem and Interpersonal Closeness.

Frontiers in psychology

Hirata E, Lodder GM, Kühnen U, Lippke S, Hermans RC.
PMID: 26733911
Front Psychol. 2015 Dec 22;6:1920. doi: 10.3389/fpsyg.2015.01920. eCollection 2015.

Although there is evidence that people tend to match their intake to that of others, less is known about the motives underlying this effect. The current study, therefore, examined the relationship between self-esteem, a specific factor that has been...

Modulated synthesis of Zr-based metal-organic frameworks: from nano to single crystals.

Chemistry (Weinheim an der Bergstrasse, Germany)

Schaate A, Roy P, Godt A, Lippke J, Waltz F, Wiebcke M, Behrens P.

Chemistry. 2011 Jun 06;17(24):6643-51. doi: 10.1002/chem.201003211. Epub 2011 May 05.

We present an investigation on the influence of benzoic acid, acetic acid, and water on the syntheses of the Zr-based metal-organic frameworks Zr-bdc (UiO-66), Zr-bdc-NH(2) (UiO-66-NH(2)), Zr-bpdc (UiO-67), and Zr-tpdc-NH(2) (UiO-68-NH(2)) (H(2) bdc: terephthalic acid, H(2) bpdc: biphenyl-4,4'-dicarboxylic acid,...

The Importance of Autonomous Regulation for Students' Successful Translation of Intentions into Behavior Change via Planning.

Advances in preventive medicine

Cao DS, Lippke S, Liu W.
PMID: 21991441
Adv Prev Med. 2011;2011:697856. doi: 10.4061/2011/697856. Epub 2011 Aug 07.

Physical activity has a high prevention potential in adolescents. This study investigated the relations between physical activity and intention, autonomous regulation, and planning. We hypothesized that planning mediates the relationship between intention and behavior and that this mediation should...
