Volkmann ischemic contracture (VIC) is a devastating condition that results from neglected compartment syndrome, which leads to prolonged ischemia, irreversible tissue necrosis, and various degrees of muscle and nerve damage, causing serious motor and sensory functional implications for the limb and a spectrum of diseases associated with worsening deformities. A thorough understanding of the anatomy and VIC pathophysiology is needed to plan an appropriate strategy. Functioning free muscle transplantation (FFMT) can restore finger movement in a paralyzed limb but requires a three-staged approach to maximize the benefits of FFMT, leading to meaningful finger extrinsic function.

Although research on the activation of C-H bonds in alkanes has been ongoing for decades, there are still few strategies that are both highly selective and suitable for industrial production. Here, we report a highly selective method for chlorination of terminal C-H bonds in alkanes by combining electrochemistry and organocatalysis. The specific cavity size of organic molecular catalysts ensures high regioselectivity, while the use of inexpensive and easily reusable graphite felt electrodes, simple electrochemical device and mild conditions enables the reaction to maintain good efficiency even when scaled up to kilogram level production.

Objectives: Blocking interleukin (IL)-6-receptor with tocilizumab has been a major advance in the treatment of giant-cell arteritis (GCA), supporting a crucial role of IL-6 receptor signalling. However, nearly half of the patients are not able to maintain glucocorticoid- free remission with tocilizumab. The impact of tocilizumab on vascular lesions of GCA is largely unknown since conflicting results have been obtained by imaging.

Background: Immunomagnetic separation is essential for screening pathogenic bacteria to prevent food poisoning. However, free immunomagnetic nanobeads (IMNBs) coexist with IMNB-bacteria conjugates (IBCs) after traditional immunomagnetic separation resulting in the infeasibility for IMNBs on IBCs to further act as signal label in bacterial detection. Although we have demonstrated that magnetophoretic separation at a high flowrate could separate IBCs from IMNBs, partial IMNBs were still found with IBCs due to chaotic flows and resulted in inevitable interferences.

Frankia spp. are multicellular actinobacteria with the ability to fix atmospheric dinitrogen (N). Frankia fixes N not only in the free-living state, but also in root-nodule symbioses with more than 200 plant species called actinorhizal plants.
