Genome-wide association study and genomic selection of brace root traits related to lodging resistance in maize.

Brace roots are the primary organs for water and nutrient absorption, and play an important role in lodging resistance. Dissecting the genetic basis of brace root traits will facilitate breeding new varieties with lodging resistance and high yield. In present study, genome-wide association study (GWAS) and genomic selection (GS) for brace root penetrometer resistance (PR), root number (RN), and tier number (TN) were conducted in a multi-parent doubled haploid (DH) population.

Cerebral amyloid angiopathy-related inflammation (CAA-ri): A case report.

Rationale: Cerebral amyloid angiopathy-related inflammation (CAA-ri) is a treatable condition characterized by an acute or subacute onset, with its primary pathological hallmark being the deposition of amyloid, predominantly β-amyloid (Aβ), within intracranial microvessels. Despite its potential for treatment, CAA-ri is a rare disorder that is frequently underrecognized by clinicians in practice. This article provides a comprehensive overview of the clinical manifestations and therapeutic approaches associated with CAA-ri, aiming to enhance awareness among healthcare professionals.

Unraveling Macrophage Polarization: Functions, Mechanisms, and "Double-Edged Sword" Roles in Host Antiviral Immune Responses.

Numerous viruses that propagate through the respiratory tract may be initially engulfed by macrophages (Ms) within the alveoli, where they complete their first replication cycle and subsequently infect the adjacent epithelial cells. This process can lead to significant pathological damage to tissues and organs, leading to various diseases. As essential components in host antiviral immune systems, Ms can be polarized into pro-inflammatory M1 Ms or anti-inflammatory M2 Ms, a process involving multiple signaling pathways and molecular mechanisms that yield diverse phenotypic and functional features in response to various stimuli.

Synergy between pluripotent stem cell-derived macrophages and self-renewing macrophages: Envisioning a promising avenue for the modelling and cell therapy of infectious diseases.

As crucial phagocytes of the innate immune system, macrophages (Mϕs) protect mammalian hosts, maintain tissue homeostasis and influence disease pathogenesis. Nonetheless, Mϕs are susceptible to various pathogens, including bacteria, viruses and parasites, which cause various infectious diseases, necessitating a deeper understanding of pathogen-Mϕ interactions and therapeutic insights. Pluripotent stem cells (PSCs) have been efficiently differentiated into PSC-derived Mϕs (PSCdMϕs) resembling primary Mϕs, advancing the modelling and cell therapy of infectious diseases.

Contribution of gut microbiota to the development of Crohn's disease: Insights gained from fecal microbiota transplantation studies in mice.

We would like to present some new thoughts on the publication in the journal published in August 2024 in . We specifically focused on the alterations in the intestinal tract, mesenteric adipose tissue (MAT), and systemic inflammatory changes in mice following fecal flora transplantation into a mouse model of Crohn's disease (CD). Accumulating evidence suggests that the occurrence of CD is influenced by environmental factors, host immune status, genetic susceptibility, and flora imbalance.

Evaluation of Comprehensive Documentation After Obstetric Anal Sphincter Injury.

Introduction And Hypothesis: The incidence of obstetric anal sphincter injuries (OASI) has increased in recent years, which may be due to improved recognition and documentation. There is limited evidence regarding the effects of thorough documentation of obstetric anal sphincter injury repairs on postpartum clinical outcomes.

Flexible Inverse Opal Structural Color Films with High Strength and Harsh Environment Stability.

Flexible photonic crystals (PCs) constructed by PCs and special polymers are very promising to achieve a combination of vivid structural colors, mechanical robustness, and environment stability. However, PCs that incorporate polymer binders are still susceptible to destruction and subsequent loss of structural color when subjected to significant external forces or harsh environments. Besides, because most of these polymers are highly flammable, crucial fire safety is difficult to be guaranteed in the application of these materials.

A study of electrochemiluminescence mechanism of Rubrene/TPrA system in an aqueous solution via stochastic collision electrochemistry in an emulsion reactor.

Background: Electrochemiluminescence (ECL) is an electrochemically induced process in which radicals generated at the electrode surface undergo exergonic electron transfer reaction to form excited states and luminesce. ECL, with high sensitivity and superior spatiotemporal control, has been widely applied in bioanalysis and light-emitting devices. The ECL signal of rubrene (Rub) was observed in Rub/TPrA oil-in-water (o/w) emulsions, which was inconsistent with the theory of ion-transfer coupled electron-transfer in Rub emulsion droplets, and the conventional ECL mechanism in Rub/TPrA system couldn't explain this phenomenon.
