Genetic Association Analysis of Dopamine DRD3 Ser9Gly Polymorphism and Schizophrenia in Malay Population [PDF]

open access: yesIranian Journal of Public Health, 2011
"nBackground: Molecular components of the dopamine receptor (DRD3) play an important role in the pathophysiology of schizophrenia (SCZ). Previous studies have demonstrated an association between the DRD3 Ser9Gly polymorphism and SCZ but the results ...

Molecular Genetic Diversity Study of Forest Coffee Tree (Coffea arabica L.) Populations in Ethiopia: Implications for Conservation and Breeding [PDF]

open access: yes, 2005
Coffee provides one of the most widely drunk beverages in the world, and is a very important source of foreign exchange income for many countries. Coffea arabica, which contributes over 70 percent of the world's coffee productions, is characterized by a ...

The revision of baphetids from the Middle Pennsylvanian of the Czech Republic: Morphology, ontogeny, palaeoecology, and the reassessment of the phylogeny of Baphetoidea

open access: yesThe Anatomical Record, EarlyView.
Abstract The baphetoids represent a clade of the Carboniferous stem‐tetrapods (Middle Mississippian—Middle Pennsylvanian) with a characteristic extension of the orbits into antorbital vacuities, which formed keyhole‐shaped openings on the skull. The more derived baphetids were crocodile‐like piscivores frequently occurring in coal‐bearing lacustrine ...

Interspecific rDNA restriction fragment length polymorphism in Globodera species, parasites of Solanaceous plants [PDF]

open access: yes, 1996
Le statut d'espèce au sein des #Globodera$ parasites des Solanacées est encore mal défini dû au faible polymorphisme morphologique détectable. Deux oligomères de 21 bases sont utilisés comme amorces pour amplifier la région non codante des ADN ...

Origin, evolution and biogeographic dynamics of the European rabbit (Oryctolagus cuniculus) in Southwestern Europe

open access: yesThe Anatomical Record, EarlyView.
Abstract The Pleistocene is a key period for understanding the evolutionary history and palaeobiogeography of the European rabbit (Oryctolagus cuniculus). The species was first documented in southeastern Iberia at the beginning of the Middle Pleistocene and appears to have rapidly spread throughout Southwestern Europe, where it was found in numerous ...

New craniodental materials of Falcarius utahensis (Theropoda: Therizinosauria) reveal patterns of intraspecific variation and cranial evolution in early coelurosaurians

open access: yesThe Anatomical Record, EarlyView.
Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

Development of DNA probes for M. tuberculosis [PDF]

open access: yes, 1992
Attempts were made to develop DNA probes for M. tuberculosis. Random library of M. tuberculosis was constructed in plasmid pGEM -4. Selection of recombinant clones was made by hybridisation with 32P labelled M. tuberculosis probe.

Early evolutionary history of the seed

open access: yesBiological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...

Sequence‐Dependent Heterotypic Assemblies of Intrinsically Disordered Peptides

open access: yesChemistryEurope, EarlyView.
Two oppositely charged intrinsically disordered peptides (IDPs) coassemble into heterotypic nanofibers. Homochiral mixtures (L/L IDPs) form homogeneous, aligned bundles with the more positive IDP. Heterochiral mixtures (L/D IDPs) yield heterogeneous, twisted bundles as positive‐IDP content increases.
