Mutation of the K transporter SlHAK5 of tomato alters pistil morphology, ionome, metabolome and transcriptome in flowers.

K accumulation in plant tissues is a crucial factor for plant growth and development. The tomato high-affinity K transporter SlHAK5 is essential for root K acquisition from low external concentrations. It is also involved in K accumulation in pollen and plant fertility as slhak5 KO plants show a low rate of pollen germination, impaired pollen tube growth and parthenocarpic fruits.

Dynamic survival analysis: Modelling the hazard function via ordinary differential equations.

The hazard function represents one of the main quantities of interest in the analysis of survival data. We propose a general approach for parametrically modelling the of the hazard function using systems of autonomous ordinary differential equations (ODEs). This modelling approach can be used to provide qualitative and quantitative analyses of the evolution of the hazard function over time.

SlCIPK9 regulates pollen tube elongation in tomato plants via a K-independent mechanism.

Potassium (K) is an essential macronutrient which contributes to osmotic- and turgor-related processes in plants. Calcineurin-B like Interacting Protein Kinases (CIPKs) play crucial roles in plants under low-K supply since they activate root K uptake transport systems such as AKT1 and AtHAK5. In Arabidopsis, AtCIPK9 is important for low-K tolerance since atcipk9 plants exhibited poor growth and leaf chlorosis when K was scarce.

Clinical outcomes for linked fixation of distal humerus fractures: a multicenter study.

Background: O'Driscoll popularized the principle of linked column fixation for distal humerus fractures. Despite the linked column concept being widely accepted, there are few reported techniques to accomplish this goal. A novel device was designed based on the principles of linked columns.
