The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis
Journal of Periodontal Research, EarlyView.Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...

New Phytologist, EarlyView.The endoplasmic reticulum (ER) is a key structure in plant cells that helps produce and transport proteins. We discovered that different Lunapark proteins shape ER structures in distinct ways, affecting protein movement and secretion. Understanding how ER structure influences function can help improve plant‐based production of valuable compounds, such ...

Impact of tether cutting on onboard navigation during the Tethered Satellite Mission-1 [PDF]
The first Tethered Satellite System mission (TSS-1) is manifested for Shuttle Flight STS-44 in January of 1991. The TSS mission presents a new challenge to engineers, requiring advanced guidance, navigation and control concepts. Current NASA flight rules

Vestigial Plastids in Parasitic Plants: Evolutionary Remnants or Adaptive Innovations?
Plant, Cell &Environment, EarlyView.ABSTRACT Throughout the evolutionary history of plants, chloroplasts originating from a cyanobacterial endosymbiosis have undergone remarkable adaptation and specialization, giving rise to a multitude of plastid types. The evolution toward parasitism in plants represents a particularly extreme case of such specialization.

Geopower, Geos and the Colonisation of Palestine
Transactions of the Institute of British Geographers, EarlyView.ABSTRACT While the majority of geographical work on colonialism in Palestine centres on territory and land, this article foregrounds geopower and geos in the making of spatial relations. Three arguments are made over three corresponding sections. The first draws on recent writing on geopower and geos (primarily that by Elizabeth Grosz, Elizabeth ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, EarlyView.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

High resolution remote sensing missions of a tethered satellite [PDF]
The application of the Tethered Satellite (TS) as an operational remote sensing platform is studied. It represents a new platform capable of covering the altitudes between airplanes and free flying satellites, offering an adequate lifetime, high ...
