Whilst tricuspid regurgitation (TR) secondary to severe mitral regurgitation (MR) is a common problem, organic TR caused by pacemaker leads is also frequently encountered. In a 63-year-old patient who developed TR attributable to both MR and a pacemaker lead inserted 12 years previously, the regurgitation could not be controlled satisfactorily using a normal ring annuloplasty. Consequently, the 'clover technique' provided an efficient correction to the TR.

We performed a systems vaccinology analysis to investigate immune responses in humans to an H5N1 influenza vaccine, with and without the AS03 adjuvant, to identify factors influencing antibody response magnitude and durability. Our findings revealed a platelet and adhesion-related blood transcriptional signature on day 7 that predicted the longevity of the antibody response, suggesting a potential role for platelets in modulating antibody response durability. As platelets originate from megakaryocytes, we explored the effect of thrombopoietin (TPO)-mediated megakaryocyte activation on antibody response longevity.

To investigate the effects of row ratio configurations on intercropping advantages and related rhizosphere microbial communities, a field experiment involving five treatments of different rows of broomcorn millet, i.e., P1M1 (1 row of broomcorn millet intercropped with 1 row of alfalfa), P2M3, P1M2, P1M3 and broomcorn millet alone (SP), was conducted on the Loess Plateau of China.

Landfilling is common in developing countries since it is the easiest and cheapest way of waste disposal, however, it leads to serious environmental problems such as soil, water, and air pollution. A landfill has a life span of fifteen years after which it is closed leaving the site unusable, as a result, effective methods are needed for restoring and reclaiming the closed landfill site for future use. Phytoremediation has emerged as a viable and environmentally friendly method, which uses green plants to remove pollutants from soil, air, and water.

Natural honey is enriched with essential and beneficial nutrients. This study aimed to investigate the melliferous flora microscopic techniques and assess the biochemical properties of honey. Flavonoid and phenolic contents in honey samples were analyzed via colorimetric and Folin-Ciocalteu methods and the alpha-amylase, reducing power, and minerals using Pull's and spectroscopy methods.

The ongoing weathering of metal sulfides has substantially posed threats to the eco-systems. For remediating metal sulfides-contaminated soils, phytostabilization is a promising nature-based technique that immobilizing heavy metals (HMs) that dissolved from metal sulfides in the rhizosphere, preventing their leaching and migrating into soil and groundwater. However, the underlying mechanism regarding the mineral-root interaction involving primary metal sulfides such as galena (PbS) during the remediation processes has yet been well studied.
