Pulmonary hypertension- a novel phenotypic hypothesis of Kabuki syndrome: a case report and literature review.

Background: Pediatric pulmonary hypertension (PH) is a serious and rare disease that is often derived from genetic mutations. Kabuki syndrome (KS) is a chromosomal abnormality disease that has its origin in the mutation of lysine methyltransferase 2D(KMT2D). Recent evidence has shown that KMT2D mutations are associated with pediatric pulmonary disorders.

[Dynamics of sap flow density in stems of typical desert shrub Calligonum mongolicum and its responses to environmental variables].

Independent measurements of stem sap flow in stems of Calligonum mongolicum and environmental variables using commercial sap flow gauges and a micrometeorological monitoring system, respectively, were made to simulate the variation of sap flow density in the middle range of Hexi Corridor, Northwest China during June to September, 2014. The results showed that the diurnal process of sap flow density in C. mongolicum showed a broad unimodal change, and the maximum sap flow density reached about 30 minutes after the maximum of photosynthetically active radiation (PAR) , while about 120 minutes before the maximum of temperature and vapor pressure deficit (VPD).
