Low sink demand caused net photosynthetic rate decrease is closely related to the irrecoverable damage of oxygen-releasing complex and electron receptor in peach trees.

Source sink balance is one of the major determinants of carbon partitioning in plants. However, its effects on photosynthesis in fruit trees are largely unknown. In this work, the effects of low sink demand on net photosynthetic rate (P) and chlorophyll fluorescence after fruit removal (-fruit) in peach (Prunus persica (L.

[Investigation of entecavir treatment in patients with LAM-refractory chronic hepatitis B].

Objective: To evaluate the efficacy and safety of entecavir (ETV) as a long-term treatment in patients with lamivudine (LAM)-refractory chronic hepatitis B (CHB).

Methods: In this phase II study of ETV-056, 32 CHB patients with resistance to LAM monotherapy were administered ETV at 1.0 mg/day and monitored over a period of 8 years.

Microfilament-binding properties of N-terminal extension of the isoform of smooth muscle long myosin light chain kinase.

Myosin light chain kinases (MLCK) phosphorylate the regulatory light chain of myosin II in thick filaments and bind to F-actin-containing thin filaments with high affinity. The ability of short myosin light chain kinase (S-MLCK) to bind F-actin is structurally attributed to the DFRXXL regions in its N-terminus. The long myosin light chain kinase (L-MLCK) has two additional DFRXXL motifs and six Ig-like modules in its N-terminal extension.
