The henipaviruses,represented by Nipah virus and Hendra virus,are emerging zoonotic viral pathogens responsible for repeated outbreaks associated with high morbidity and mortality in Australia,Southeast Asia,India and Bangladesh. These viruses enter host cells via a class I viral fusion mechanism mediated by their attachment and fusion envelope glycoproteins;efficient membrane fusion requires both these glycoproteins in conjunction with specific virus receptors present on susceptible host cells. The henipavirus attachment glycoprotein interacts with a cellular B class ephrin protein receptor triggering conformational alterations leading to the activation of the viral fusion(F) glycoprotein. The analysis of monoclonal antibody(mAb) reactivity with G has revealed measurable alterations in the antigenic structure of the glycoprotein following its binding interaction with receptor. These observations only appear to occur with full-length native G glycoprotein,which is a tetrameric oligomer,and not with soluble forms of G(sG) ,which are disulfide-linked dimers. Single amino acid mutations in a heptad repeat-like structure within the stalk domain of G can disrupt its association with F and subsequent membrane fusion promotion activity. Notably,these mutants of G also appear to confer a post-receptor bound conformation implicating the stalk domain as an important element in the G glycoprotein's structure and functional relationship with F. Together,these observations suggest fusion is dependent on a specific interaction between the F and G glycoproteins of the henipaviruses. Further,receptor binding induces measurable changes in the G glycoprotein that appear to be greatest in respect to the interactions between the pairs of dimers comprising its native tetrameric structure. These receptor-induced conformational changes may be associated with the G glycoprotein's promotion of the fusion activity of F.

climate change is making it more challenging to meet the food demands of a growing global *** food produc-tion relies on continual crop improvements to generate higher and more stable yields,especially with increasingly unpredictable environments and less arable *** improvement of traits that promote climate resilience and resource utilization,for example,greater photosynthetic capacity,increased nitrogen use efficiency,and optimized root and shoot architecture,repre-sents a promising avenue for engineering crops to yield more with less(Evans and Lawson,2020).A key challenge for crop engineering is optimizing performance in specific environments.

We investigated the effects of different cO2 tensions on oxygenation, pulmonary blood flow(Qp), cerebral blood flow, and systemic blood flow(Qs) after the bidirectional superior cavopulmonary anastomosis (BcPA). Hypoxemia refractory to management of a high pulmonary vascular resistance index(PVRI) may complicate recovery from the BcPA. After BcPA, cO2 was added to the inspired gas of mechanically ventilated patients. The Qp, Qs, PVRI, and systemic vascular resistance index(SVRI) were calculated from oxygen consumption, intravascular pressures, and oxygen saturations. cerebral blood flow was estimated by near infrared spectroscopy and transcranial Doppler. In nine patients(median age 7.1, range 2 to 23 months), arterial oxygen tension increased significantly (pcarbon dioxide tensions (PacO2) of 35, 45, and 55 mm Hg, respectively and decreased to 40±8 mm Hg at PacO2 40 mm Hg. At a PacO2 of 55 and 45 compared with 35 mm Hg, Qp, cerebral blood flow, and Qs increased significantly, PVRI, Qp/Qs, and the ratio of Qp to inferior vena caval blood flow were unchanged, but SVRI decreased. We have demonstrated that after the BcPA, systemic oxygenation, Qp, Qs, and cerebral blood flow increased and SVRI decreased at cO2 tensions of 45 and 55 mm Hg compared with 35 mm Hg. We suggest that hypoxemia after the BcPA is ameliorated by a higher PacO2 and that low PacO2 or alkalosis may be detrimental. Hypercarbic management strategies may allow earlier progression to the BcPA, which may contribute to reducing the interval morbidity in patients with a functional single ventricle.
