Article Synopsis
  • Researchers have developed a new method for remote functionalization that uses a borenium ion as a catalyst instead of traditional transition metals, addressing issues like metal residue and catalyst poisoning.
  • The process allows for site-selective modification of molecules by enabling the "walking" of a boron group along a carbon chain, ultimately favoring the formation of α-borylation products.
  • This metal-free approach shows compatibility with various functional groups and can facilitate the synthesis of unique compounds, including those helpful in creating bioactive molecules.

The complete blood count (CBC) is an important screening tool for healthy adults and a common test at periodic exams. However, results are usually interpreted relative to one-size-fits-all reference intervals, undermining the precision medicine goal to tailor care for patients on the basis of their unique characteristics. Here we study thousands of diverse patients at an academic medical centre and show that routine CBC indices fluctuate around stable values or setpoints, and setpoints are patient-specific, with the typical healthy adult's nine CBC setpoints distinguishable as a group from those of 98% of other healthy adults, and setpoint differences persist for at least 20 years.

Metal hydrides are sensitive to HO and O, which reduces the atom efficiency of the hydride donors. Silver (Ag) is an inexpensive coinage metal; however, its lower activity compared to gold, platinum, and palladium limits its application in catalytic hydrogenation. Here, electron-deficient metallic single-atom Ag (AgSA) was loaded onto γ-AlO using a benzoquinone- and KNO- assisted photolysis approach.

High-internal-phase water-in-oil (W/O) emulsions generated in situ have garnered considerable attention as novel profile control systems. However, conventional emulsifiers are unreactive and poorly dispersed in water, necessitating large dosages and resulting in poor injectivity. In this study, we synthesized amphiphilic nanoparticles (SiO-NH-DAC NPs) containing amine and long-chain alkyl groups using a one-pot method and investigated the stabilized emulsion properties.

  • This study explores how varying the ratio of binder materials (lime, cement, and coal gangue powder) to hemp shives affects the physical and mechanical properties of lime-hemp concrete (LHC).
  • Five different binder to hemp shives mass ratios (1.2 to 2.0) were tested, revealing that a higher binder content improved drying speed, strength, and thermal conductivity, while decreasing water absorption.
  • Advanced microstructural analyses showed that increased binder led to more hydration products, enhancing the material’s density and strength by filling internal voids and bonding effectively with hemp fibers.

Endocytosis and lysosomal trafficking of cell surface receptors can be triggered by endogenous ligands. Therapeutic approaches such as lysosome-targeting chimaeras (LYTACs) and cytokine receptor-targeting chimeras (KineTACs) have used this to target specific proteins for degradation by fusing modified native ligands to target binding proteins. Although powerful, these approaches can be limited by competition with native ligands and requirements for chemical modification that limit genetic encodability and can complicate manufacturing, and, more generally, there may be no native ligands that stimulate endocytosis through a given receptor.

Article Synopsis
  • The Claustrum/dorsal endopiriform cortex complex (CLA) is a complex brain region that heavily influences other cortical areas and expresses the transcription factor Nurr1, whose specific role in CLA was not clearly defined.
  • Research using genetically modified mice demonstrated that Nurr1 is essential for maintaining the unique gene expression pattern of CLA neurons, although these neurons remain physically intact without it.
  • The study also found that Nurr1 deletion in CLA disrupts hallucinogen receptor expression and alters the functional connectivity effects of hallucinogens on brain regions that interact with CLA, suggesting that targeting Nurr1 could enhance our understanding of CLA’s functions.

The innovation of synthetic strategies for selective B-H functionalization is a pivotal objective in the realm of boron cluster chemistry. However, the precise, efficient, and rapid functionalization of a B-H bond of carboranes that is distant from the existing functional groups remains intractable owing to the limited approaches for site-selective control from the established methods. Herein, we report a dative bonding activation strategy for the selective functionalization of a nonclassical remote B-H site of -carboranes.

While lithium borohydride is one of the most promising hydrogen storage materials due to its ultrahigh hydrogen storage density, high thermodynamic stability, kinetic barriers, and poor reversibility, it is far from being used in practical applications. Herein, we prepare a cubic hollow carbon dodecahedron uniformly modified with a bimetallic CoNi alloy (CoNi/NC) for preserving the stable catalytic effect of CoNi alloys toward reversible hydrogen storage. It is theoretically confirmed that bimetallic CoNi alloys effectively weaken the B-H bonds of LiBH by extending their average length to 1.

Article Synopsis
  • Personalized neoantigen therapy can help some cancer patients, but not everyone has enough of the right markers (neoantigens) for it to work.
  • Some mutations in tumors don't make the immune system react, meaning some patients won't benefit from this treatment.
  • Scientists suggest using a special ingredient called p-nitrophenylalanine (pNOPhe) to tweak these mutations, making them better at activating the immune system and possibly helping more patients be treated successfully.
