Background: Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is recommended for patients with KMT2A-rearranged (KMT2A-r) leukemia whereas relapse remains high. We aimed to determine whether intensified conditioning containing decitabine (Dec) could reduce relapse compared with standard myeloablative conditioning in adult patients with KMT2A-r leukemia.

Methods: We performed a multicenter retrospective study at seven institutions in China.

Flexible and diverse manipulation of electromagnetic (EM) waves in half space (reflection or transmission) has facilitated strong aspiration toward full-space wave control. However, it remains challenging to achieve independent amplitude and phase control, which seriously hinder the real-world applications. Herein, an innovative strategy of trifunctional metasurface is proposed to independently and simultaneously manipulate the amplitude and phase of circular polarized waves in full space.

Dietary interventions have been shown to improve gut health by altering the gut flora, preventing obesity, and mitigating inflammatory disorders. This study investigated the benefits of a rice starch-konjac glucomannan (ERS-KGM) complex, produced screw extrusion, for gut health and obesity prevention. Analyzed through starch digestion, scanning electron microscopy, and structural analysis, the ERS-KGM complex exhibited a notable increase in resistant starch content due to its well-ordered structure.

Article Synopsis
  • Leaves vary in shape, from simple to complex forms, with Arabidopsis thaliana serving as a key model to study this diversity, especially the factors influencing serration.
  • The boundary regulatory factors CUC2 and CUC3 are crucial for promoting leaf serration, while WOX1 plays a significant role in controlling the number and size of teeth by regulating CUC3 levels.
  • This research reveals that BZR1 interacts with WOX1 to modulate CUC3 expression, forming a complex regulatory mechanism that fine-tunes leaf margin development.

Promiscuous enzymes often serve as the starting point for the evolution of novel functions. Yet, the extent to which the promiscuity of an individual enzyme can be harnessed several times independently for different purposes during evolution is poorly reported. Here, we present a case study illustrating how NAD(P)-dependent succinate semialdehyde dehydrogenase of Escherichia coli (Sad) is independently recruited through various evolutionary mechanisms for distinct metabolic demands, in particular vitamin biosynthesis and central carbon metabolism.

Molecular sieving is an ideal separation mechanism, but controlling pore size, restricting framework flexibility, and avoiding strong adsorption are all very challenging. Here, we report a flexible adsorbent showing molecular sieving at ambient temperature and high pressure, even under high humidity. While typical guest-induced transformations are observed, a high transition pressure of 16.

Background: Rice starch has high digestibility due to its large carbohydrate content. Synergistic modification of hot-melt extrusion (HME) and additives such as flavonoids, hydrocolloids, proteins, lipids, and other additives has the tendency to retard the rate of starch hydrolysis. Hence, the current investigation aimed to study the combined effect of the HME-assisted addition of nobiletin (NOB, 0, 2, 4, and 6%) on the multi-scale structures, interactions, thermal, and digestibility characteristics of rice starch.

  • The study aimed to evaluate how well the thickness of the macular ganglion cell-inner plexiform layer (mGCIPLT) and 10-2 visual field (VF) metrics can identify early glaucoma and assess severe glaucoma cases.
  • Researchers analyzed 127 eyes from 89 participants, correlating OCT-derived mGCIPLT measurements with VF sensitivity for both early and advanced glaucoma.
  • Findings showed mGCIPLT had strong correlations with VF patterns, particularly in early glaucoma with central visual field damage, outperforming other parameters for diagnosis, suggesting their combined use can enhance glaucoma detection and severity assessment.

Synthetic biology aims at designing new biological functions from first principles. These new designs allow to expand the natural solution space and overcome the limitations of naturally evolved systems. One example is synthetic CO-fixation pathways that promise to provide more efficient ways for the capture and conversion of CO than natural pathways, such as the Calvin Benson Bassham (CBB) cycle of photosynthesis.

Hybrid lethality is a type of reproductive isolation barrier observed in two developmental stages, hybrid embryos (hybrid seeds) and hybrid seedlings. Hybrid lethality has been reported in many plant species and limits distant hybridization breeding including interspecific and intergeneric hybridization, which increases genetic diversity and contributes to produce new germplasm for agricultural purposes. Recent studies have provided molecular and genetic evidence suggesting that underlying causes of hybrid lethality involve epistatic interaction of one or more loci, as hypothesized by the Bateson-Dobzhansky-Muller model, and effective ploidy or endosperm balance number.
