The Protective Role of Non-Photochemical Quenching in PSII Photo-Susceptibility: A Case Study in the Field.

Non-photochemical quenching (NPQ) has been regarded as a safety valve to dissipate excess absorbed light energy not used for photochemistry. However, there exists no general consensus on the photoprotective role of NPQ. In the present study, we quantified the Photosystem II (PSII) photo-susceptibilities (mpi) in the presence of lincomycin, under red light given to five shade-acclimated tree species grown in the field.

Insight into the reversible conversion-(de)incorporation of redox-active dopants within a polymer-based electrode.

We combined a microporous polymer backbone with an organic redox-active dopant to construct a reversible electrode system based on the conversion-(de)incorporation behaviour of the dopant. The correspondence between the reversible conversion-(de)incorporation mechanism of the dopant and the electrochemical performance of the designed electrode system was established by electrochemical quartz crystal microbalance and in situ Fourier transform infrared spectroscopy.

Stomatal Sensitivity to Vapor Pressure Deficit and the Loss of Hydraulic Conductivity Are Coordinated in , a Desert Phreatophyte Species.

There are considerable variations in the percentage loss of hydraulic conductivity () at mid-day minimum water potential among and within species, but the underpinning mechanism(s) are poorly understood. This study tested the hypothesis that plants can regulate leaf specific hydraulic conductance ( ) precise control over under variable Δ (water potential differential between soil and leaf) conditions to maintain the constant (: the sensitivity of stomatal conductance to ; : reference stomatal conductance at 1.0 kPa ), where is vapor pressure deficit.

Osteoclast-derived miR-23a-5p-containing exosomes inhibit osteogenic differentiation by regulating Runx2.

Background: Some microRNAs (miRNAs) are involved in osteogenic differentiation. In recent years, increasing evidences have revealed that exosomes contain specific miRNAs. However, the effect and mechanism of miR-23a-5p-containing exosomes in osteoblast remain largely unclear.

Network Meta-Analysis of Pharmacological Agents for Osteoporosis Treatment and Fracture Prevention.

Background And Objective: Osteoporosis afflicts a large number of populations in the world and is featured by systemic impairment of bone mass and strength which may further trigger an increase in the risk of fragile fractures. This network meta-analysis (NMA) is designed to distinguish therapies more preferable than others with respect to efficacy and safety.

Methods: We searched the medical literature for relevant studies systematically.

Greater trochanter osteotomy with cementless THA for Crowe type IV DDH.

This study explored the surgical method and short-term clinical effect of a greater trochanter osteotomy along with cementless artificial total hip arthroplasty in the treatment of Crowe type IV developmental dysplasia of the hip. The authors conducted a retrospective analysis of 18 patients (22 hips) with Crowe type IV dysplasia who were seen between June 2008 and August 2010. After undergoing cementless artificial total hip arthroplasty using a posterolateral approach, a greater trochanter osteotomy was used to adjust the tension of the gluteal muscle, and an acetabular cup was placed.

Lower-limb valgus deformity associated with developmental hip dysplasia.

Background: Treating developmental dysplasia of the hip is often challenging. The difficulties include not only the hip surgery itself but also the treatment of the associated lower-limb valgus deformity. However, there have been very few studies on such deformity in patients with developmental hip dysplasia.

[Effects of controlled-release fertilizer and organic amendment on the construction of nutrients reserves in Larix olgensis container seedlings].

A 2 x 2 factorial experiment was conducted to study the effect of fertilization on Larix olgensis container seedlings. 36.36 or 18.
