Optical Response of Solid CO$_2$ as a Tool for the Determination of the High Pressure Phase

open access: yes, 2003
We report first-principles calculations of the frequency dependent linear and second-order optical properties of the two probable extended-solid phases of CO$_2$--V, i.e. $I\bar42d$ and $P2_12_12_1$. Compared to the parent $Cmca$ phase the linear optical

Molecular dissection of the mechanism by which EWS/FLI expression compromises actin cytoskeletal integrity and cell adhesion in Ewing sarcoma. [PDF]

open access: yes, 2014
Ewing sarcoma is the second-most-common bone cancer in children. Driven by an oncogenic chromosomal translocation that results in the expression of an aberrant transcription factor, EWS/FLI, the disease is typically aggressive and micrometastatic upon ...

Fruit Traits Reflect Adaptation to Dispersers Along a Tropical Elevational Gradient

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
This study investigates how fruit traits related to frugivore dispersal—specifically diameter, colour and presentation—vary along an elevation gradient in Papua New Guinea. Results showed that fruit diameter decreases with elevation, bird‐attracting colours are more common at higher elevations, and branch‐borne (ramiflorous) fruits increase with ...

Langage reflétant une différence culturelle

open access: yesCahiers Balkaniques, 2013
As the pig is a taboo animal for the Moslems, one may expect that their image of it is different from that of the Christians, for whom this animal has an image with multiple, both positive and negative facets, but is not taboo. So the “pig” may give us a

Stage-Specific Timing of the microRNA Regulation of \u3cem\u3elin-28\u3c/em\u3e by the Heterochronic Gene \u3cem\u3elin-14\u3c/em\u3e in \u3cem\u3eCaenorhabditis elegans\u3c/em\u3e [PDF]

open access: yes, 2017
In normal development, the order and synchrony of diverse developmental events must be explicitly controlled. In the nematode Caenorhabditis elegans, the timing of larval events is regulated by hierarchy of proteins and microRNAs (miRNAs) known as the ...

miR‐701 modulates the humoral immune response of Coptotermes formosanus against Metarhizium anisopliae

open access: yesInsect Science, Volume 32, Issue 6, Page 1822-1837, December 2025.
miR‐701 targets immune gene Toll4 to inhibit termite cellular immunity. miR‐701 overexpression increases termite mortality during fungal infection. miR‐701 suppresses termite cellular immune to fungi by inhibiting the Toll signaling pathway. Abstract Termites are not only social insects but also significant global insect pests.

Patterning of the C. elegans 1° vulval lineage by RAS and Wnt pathways [PDF]

open access: yes, 2000
In C. elegans, the descendants of the 1° vulval precursor cell (VPC) establish a fixed spatial pattern of two different cell fates: E-F-F-E. The two inner granddaughters attach to the somatic gonadal anchor cell (AC) and generate four vulF cells, while ...

Downregulation of Chromosome 19 miRNA Cluster and the Tumor‐Suppressive Role of miR‐517a‐3p in Choriocarcinoma

open access: yesCancer Science, Volume 116, Issue 12, Page 3473-3486, December 2025.
Chromosome 19 microRNA cluster was downregulated in choriocarcinoma compared with complete hydatidiform mole. miR‐517a‐3p reduced the proliferation, migration, and invasion abilities of choriocarcinoma cell lines. Downregulation of SRSF1, targeted by miR‐517a‐3p, suppressed the malignant potential of choriocarcinoma cell lines. ABSTRACT Choriocarcinoma

Construction of a "mutagenesis cartridge" for poliovirus genome-linked viral protein: Isolation and characterization of viable and nonviable mutants [PDF]

open access: yes, 1988
By following a strategy of genetic analysis of poliovirus, we have constructed a synthetic "mutagenesis cartridge" spanning the genome-linked viral protein coding region and flanking cleavage sites in an infectious cDNA clone of the type 1 (Mahoney ...
