Science teachers' views and practices in planning for teaching

Science teachers

Sánchez G.
GSID: pZpfr5HR3X0J
G Sánchez, MV Valcárcel - Journal of Research in Science …, 1999 - Wiley Online Library

… a group of secondary school science teachers toward lesson planning. The two main questions posed are: “What do teachers do when they prepare their lessons?” and “What do teachers think of their own planning?” We describe the decisions...

Comparison of the in vivo and in vitro genotoxicity of glyphosate isopropylamine salt in three different organisms.

Genetics and molecular biology

Alvarez-Moya C, Silva MR, Ramírez CV, Gallardo DG, Sánchez RL, Aguirre AC, Velasco AF.
PMID: 24688297
Genet Mol Biol. 2014 Mar;37(1):105-10. doi: 10.1590/s1415-47572014000100016. Epub 2013 Feb 28.

There is considerable controversy with regard to the genotoxicity of glyphosate, with some reports stating that this compound is non-toxic for fish, birds and mammals. In this work, we used the comet assay to examine the genotoxicity of glyphosate...

Theory of Inpatient Circadian Care (TICC): A Proposal for a Middle-Range Theory.

The open nursing journal

Camargo-Sanchez A, Niño CL, Sánchez L, Echeverri S, Gutiérrez DP, Duque AF, Pianeta O, Jaramillo-Gómez JA, Pilonieta MA, Cataño N, Arboleda H, Agostino PV, Alvarez-Baron CP, Vargas R.

The circadian system controls the daily rhythms of a variety of physiological processes. Most organisms show physiological, metabolic and behavioral rhythms that are coupled to environmental signals. In humans, the main synchronizer is the light/dark cycle, although non-photic cues...

Pathway Complexity Versus Hierarchical Self-Assembly in N-Annulated Perylenes: Structural Effects in Seeded Supramolecular Polymerization.

Angewandte Chemie (International ed. in English)

Studies were carried out on the hierarchical self-assembly versus pathway complexity of N-annulated perylenes 1-3, which differ only in the nature of the linking groups connecting the perylene core and the side alkoxy chains. Despite the structural similarity, compounds...

Gastrointestinal Stromal Tumor: Cause of Gastrointestinal Bleeding.

Gastroenterology research

Vilallonga R, Sanchez JL, Armengol M.
PMID: 27956992

PURPOSE: This study aimed to determine the prevalence and severity of recurrent wheezing (RW) defined as ≥3 episodes of wheezing, risk factors, and treatments prescribed during the first year of life in Latin American infants.METHODS: In this international, cross-sectional,...

Helical supramolecular polymerization of C3-symmetric amides and retroamides: on the origin of cooperativity and handedness.

Chemical communications (Cambridge, England)

Buendía J, Calbo J, García F, Aragó J, Viruela PM, Ortí E, Sánchez L.
PMID: 27142262
Chem Commun (Camb). 2016 May 25;52(42):6907-10. doi: 10.1039/c6cc02681h. Epub 2016 May 04.

The cooperative supramolecular polymerization of 1 and 2 yields P- or M-type helical aggregates depending on the absolute configuration (S or R) of the stereogenic centres attached to the side chains. The connectivity of the amide group does not...

Evaluating The Effect Of Immunotherapy In Advanced Non-Small- Cell Lung Cancer Patients Using Two Components Mixture Model.

Solvent-Directed Helical Stereomutation Discloses Pathway Complexity on N-Heterotriangulene-Based Organogelators.

Chemistry (Weinheim an der Bergstrasse, Germany)

Valera JS, Sánchez-Naya R, Ramírez FJ, Zafra JL, Gómez R, Casado J, Sánchez L.
PMID: 28590076

The chiroptical features of supramolecular polymers formed from N-heterotriangulenes 1-3 have been investigated by circular dichroism (ECD) and vibrational circular dichroism (VCD) techniques. In solution, the CD spectra demonstrate that the helicity of the aggregates depends on only the...

Transition metal dichalcogenides (TMDCs), together with other two-dimensional (2D) materials, have attracted great interest due to the unique optical and electrical properties of atomically thin layers. In order to fulfill their potential, developing large-area growth and understanding the properties...

The gene fl(2)d is required for various Sxl-controlled processes in Drosophila females.

Roux's archives of developmental biology : the official organ of the EDBO

Granadino B, San Juán AB, Sánchez L.
PMID: 28306022
Rouxs Arch Dev Biol. 1991 Aug;200(3):172-176. doi: 10.1007/BF00190237.

In Drosophila melanogaster, the gene Sex-lethal (Sxl) controls the processes of sex determination, dosage compensation, oogenesis and sexual behaviour. The control of Sxl is by alternative splicing of its primary RNA. We have identified a gene, female-lethal-2-d (fl(2)d), which...

Cholesterol removal from adult skeletal muscle impairs excitation-contraction coupling and aging reduces caveolin-3 and alters the expression of other triadic proteins.

Frontiers in physiology

Front Physiol. 2015 Apr 10;6:105. doi: 10.3389/fphys.2015.00105. eCollection 2015.

Cholesterol and caveolin are integral membrane components that modulate the function/location of many cellular proteins. Skeletal muscle fibers, which have unusually high cholesterol levels in transverse tubules, express the caveolin-3 isoform but its association with transverse tubules remains contentious....
