Limited effects of xylem anatomy on embolism resistance in cycad leaves.

Drought-induced xylem embolism is a primary cause of plant mortality. Although c. 70% of cycads are threatened by extinction and extant cycads diversified during a period of increasing aridification, the vulnerability of cycads to embolism spread has been overlooked.

Coordination of intertracheid pit traits and climate effects among cycads.

Interconduit pit membranes, which are permeable regions in the primary cell wall that connect to adjacent conduits, play a crucial role in water relations and the movement of nutrients between xylem conduits. However, how pit membrane characteristics might influence water-carbon coupling remains poorly investigated in cycads. We examined pit characteristics, the anatomical and photosynthetic traits of 13 cycads from a common garden, to determine if pit traits and their coordination are related to water relations and carbon economy.

Characterization of the complete chloroplast genome of mangrove L.) Lam. ex Savigny.

The chloroplast (cp) genome sequence of was characterized. The cp genome length was 163,795 bp in length, with a GC content of 35.3%, containing a large single copy (LSC) of 90,830 bp, a small single copy (SSC) of 20,207 bp, and a pair of inverted repeats (IRs) of 26,379 bp.

Characterization of the complete chloroplast genome of mangrove Blume (Rhizophoraceae).

The chloroplast (cp) genome sequence of was characterized. The cp genome length was 164,343 bp in length, containing a typical structure of a large single copy (LSC) of 93,155 bp, a small single copy (SSC) of 19,376 bp, and two inverted repeats (IRs) of 25,906 bp, with a GC content of 34.9%.

[Risk factors of cubitus varus in humeral condylar fracture after conservative treatment in child].

Objective: To further investigate the risk factors of cubitus varus in humeral condylar fracture after conservative treatment in children through Logistic regression analysis, so as to guide the clinical treatment.

Methods: Children with humeral condylar fracture who were treated by manipulative reduction and plaster fixation in our hospital from March 2008 to December 2014 were studied. The clinical data including age, gender, BMI, time from injury to reduction, direction of displacement, rotation displacement, fixed position, and epiphyseal injury were collected.
