Diverse plant RNAs coat leaves and are distinct from apoplastic RNAs.

Transgenic expression of a double-stranded RNA in plants can induce silencing of homologous mRNAs in fungal pathogens. Although such host-induced gene silencing is well documented, the molecular mechanisms by which RNAs can move from the cytoplasm of plant cells across the plasma membrane of both the host cell and fungal cell are poorly understood. Indirect evidence suggests that this RNA transfer may occur at a very early stage of the infection process, prior to breach of the host cell wall, suggesting that silencing RNAs might be secreted onto leaf surfaces.

CD206+ Trem2+ macrophage accumulation in the murine knee joint after injury is associated with protection against post-traumatic osteoarthritis in MRL/MpJ mice.

Post-traumatic osteoarthritis (PTOA) is a painful joint disease characterized by the degradation of bone, cartilage, and other connective tissues in the joint. PTOA is initiated by trauma to joint-stabilizing tissues, such as the anterior cruciate ligament, medial meniscus, or by intra-articular fractures. In humans, ~50% of joint injuries progress to PTOA, while the rest spontaneously resolve.

Basic Science and Pathogenesis.

Background: Examining the neuropathology of the oldest-old has significantly advanced our understanding of the multiple etiologies in very late life. Most studies have included exclusively White decedents with limited ethnoracial diversity. Our goal was to characterize neuropathology in a cohort of ethnically and racially diverse oldest-old decedents.

Basic Science and Pathogenesis.

Background: Alzheimer's disease (AD) missing heritability remains extensive despite numerous genetic risk loci identified by genome-wide association or sequencing studies. This has been attributed, at least partially, to mechanisms not currently investigated by traditional single-marker/gene approaches. Polygenic Risk Scores (PRS) aggregate sparse genetic information across the genome to identify individual genetic risk profiles for disease prediction and patient risk stratification.

For example, a sample of participants with normal cognition, mild cognitive impairment (MCI), and dementia might be divided into subgroups to answer questions about whether some exposure variable (e.g.

Stage at diagnosis and cancer-specific survival for stomach, lung, colorectal, and bladder cancers among Armenians in California.

Objective: To observe stage at diagnosis and cancer-specific survival for common cancers among Armenians in California.

Methods: We used the Armenian Surname List and birthplace information in the California Cancer Registry to identify Armenians with stomach, lung, colorectal, and bladder cancers diagnosed during 1988-2019. We used multivariable logistic regression models to calculate odds of late-stage diagnoses among Armenian and non-Armenian, non-Hispanic White patients and examine the association of sociodemographic factors with late-stage diagnoses among the Armenian patient population.

Associations of prenatal urinary melamine, melamine analogues, and aromatic amines with gestational duration and fetal growth in the ECHO Cohort.

Melamine, its analogues, and aromatic amines (AAs) were commonly detected in a previous study of pregnant women in the Environmental influences on Child Health Outcomes (ECHO) Cohort. While these chemicals have identified toxicities, little is known about their influences on fetal development. We measured these chemicals in gestational urine samples in 3 ECHO cohort sites to assess associations with birth outcomes (n = 1,231).

Community Synchrony in Seed Production is Associated With Trait Similarity and Climate Across North America.

Mast seeding, the synchronous and highly variable production of seed crops by perennial plants, is a population-level phenomenon and has cascading effects in ecosystems. Mast seeding studies are typically conducted at the population/species level. Much less is known about synchrony in mast seeding between species because the necessary long-term data are rarely available.

Surface electromyography evaluation for decoding hand motor intent in children with congenital upper limb deficiency.

Children born with congenital upper limb absence exhibit consistent and distinguishable levels of biological control over their affected muscles, assessed through surface electromyography (sEMG). This represents a significant advancement in determining how these children might utilize sEMG-controlled dexterous prostheses. Despite this potential, the efficacy of employing conventional sEMG classification techniques for children born with upper limb absence is uncertain, as these techniques have been optimized for adults with acquired amputations.

Non-antibiotic approaches to mitigating wound infections: Potential for SSRIs and adrenergic antagonists as emerging therapeutics.

Bacterial biofilms represent a formidable challenge in the treatment of chronic wounds, largely because of their resistance to conventional antibiotics. The emergence of multidrug-resistant (MDR) bacterial strains exacerbates this issue, necessitating a shift towards exploring alternative therapeutic approaches. In response to this urgent need, there has been a surge in research efforts aimed at identifying effective non-antibiotic treatments.

CABG Should Be a Subspecialty.

Subspecialization in surgery is increasingly common and for great reasons. Over the past twenty years, there is evidence in support of link between sub-specialization in the disciplines of orthopedic surgery, general, thoracic surgery, neurosurgery, and in interventional cardiology and better patient outcomes and technical advances in their respective fields. In addition, studies suggest increased hospital and surgeon volume throughout surgery may lead to improved surgical outcomes.

Plastid-nuclear coevolution of ribosomal protein genes in papilionoid legumes.

In plants, cellular function is orchestrated by three distinct genomes located within the nucleus, mitochondrion, and plastid. These genomes are interdependent, requiring tightly coordinated maintenance and expression. Plastids host several multisubunit protein complexes encoded by both the plastid and nuclear genomes.
