Diapause in Microplitis mediator Haliday (Hymenoptera: Braconidae) is manifested during the pupal stage and normally occurs during the winter season because of a photoperiodic response that is highly dependent on temperature. No diapause was observed at temperatures above 20 Cregardless of the photoperiod.Only a small part of the population entered diapause at 20 Cunder short daylengths of ligh...

Photometric observations of occultations transiting exoplanets can place important constraints on the thermal emission and albedos their atmospheres. We analyse photometric measurements derive geometric albedo ($A_\mathrm{g}$) for five hot Jupiters observed with TESS in optical: WASP-18 b, WASP-36 WASP-43 WASP-50 b WASP-51 b. For our results are complemented by a VLT/HAWK-I observation near-inf...

Abstract Studies of exoplanetary atmospheres have found no definite correlations between observed high-altitude aerosols and other system parameters. This could be, in part, because the lack homogeneous exoplanet samples for which specific parameters can be isolated inspected. Here, we present a set seven exoplanets with very similar We analyze existing photometric time series, Gaia parallax, h...

BACKGROUND The actin-related proteins Arp2 and Arp3 are part of a seven-protein complex which is localized in the lamellipodia of a variety of cell types, and in actin-rich spots of unknown function. The Arp2/3 complex enhances actin nucleation and causes branching and crosslinking of actin filaments in vitro; in vivo it is thought to drive the formation of lamellipodia and to be a control cent...

in 2013, we launched a project to collect and identify the insects, which were associated with the pistachio gall aphid species forda hirsuta mordv. and slavum mordvilovi kreutz in tang-shekan region of the city of arsanjan in the province of fars. we collected the ichneumonid wasp aneuclis melanaria (holmgren) of the subfamily tersilochinae on the aphid populations of s. mordvilovi. this paras...

To propel itself in infected cells, the pathogen Shigella flexneri subverts the Cdc42-controlled machinery responsible for actin assembly during filopodia formation. Using a combination of bacterial motility assays in platelet extracts with Escherichia coli expressing the Shigella IcsA protein and in vitro analysis of reconstituted systems from purified proteins, we show here that the bacterial...

In studies aimed at further characterizing the cellular immunodeficiency of the Wiskott-Aldrich syndrome (WAS), we found that T lymphocytes from WAS patients display abnormal chemotaxis in response to the T-cell chemoattractant stromal cell-derived factor (SDF)-1. The Wiskott- Aldrich syndrome protein (WASP), together with the Rho family GTPase Cdc42, control stimulus-induced actin cytoskeleton...

Metastasizing tumor cells use matrix metalloproteases, such as the transmembrane collagenase MT1-MMP, together with actin-based protrusions, to break through extracellular matrix barriers and migrate in dense matrix. Here we show that the actin nucleation-promoting protein N-WASP (Neural Wiskott-Aldrich syndrome protein) is up-regulated in breast cancer, and has a pivotal role in mediating the ...

The pathophysiology of microthrombocytopenia in the Wiskott-Aldrich syndrome (WAS) and its milder form, X-linked thrombocytopenia (XLT), is unclear. Although quantitative defects are correctable by splenectomy, residual platelet abnormalities are suggestive of intrinsic disturbances of production. In contrast to human patients, murine models of WASp deficiency exhibit only mild thrombocytopenia...
