Strigolactones regulate Bambusa multiplex sheath senescence by promoting chlorophyll degradation.

Culm sheaths are capable of photosynthesis and are an important class of non-leaf organs in bamboo plants. The source-sink interaction mechanism has been found to play an important role in the interaction between culm sheaths and internodes in Bambusa multiplex. Research on the regulatory mechanisms of culm sheath senescence is important for the study of internode growth, but reports in this regard are limited.

The Johns Hopkins Hope at Hopkins Clinic: supporting the comprehensive needs of individuals with metastatic breast cancer.

Purpose: Individuals with metastatic breast cancer (MBC) may live with their disease for many years. We initiated the Johns Hopkins Hope at Hopkins Clinic to assess the needs and optimize the care of these patients.

Patients And Methods: Patients with MBC who agreed to participate in the Clinic in addition to usual care completed patient-reported outcome (PRO) surveys.

Association of Obstructive Sleep Apnea and Nocturnal Hypoxemia With the Circadian Rhythm of Myocardial Infarction.

Background: The circadian rhythm of myocardial infarction (MI) in patients with obstructive sleep apnea (OSA) remains disputable and no studies have directly evaluated the relationship between nocturnal hypoxemia and the circadian rhythm of MI. The aim of the current study was to evaluate the association of OSA and nocturnal hypoxemia with MI onset during the night.

Methods: Patients with MI in the OSA-acute coronary syndrome (ACS) project (NCT03362385) were recruited.

Advancements in MEMS Micromirror and Microshutter Arrays for Light Transmission Through a Substrate.

This paper reviews and compares electrostatically actuated MEMS (micro-electro-mechanical system) arrays for light modulation and light steering in which transmission through the substrate is required. A comprehensive comparison of the technical achievements of micromirror arrays and microshutter arrays is provided. The main focus of this paper is MEMS micromirror arrays for smart glass in building windows and façades.

MEMS Smart Glass with Larger Angular Tuning Range and 2D Actuation.

Millions of electrostatically actuatable micromirror arrays have been arranged in between windowpanes in inert gas environments, enabling active daylighting in buildings for illumination and climatization. MEMS smart windows can reduce energy consumption significantly. However, to allow personalized light steering for arbitrary user positions with high flexibility, two main limitations must be overcome: first, limited tuning angle spans by MEMS pull-in effects; and second, the lack of a second orthogonal tuning angle, which is highly required.

[Training Present and Future Doctors for Chile: How Many and For What? The Urgent Need to Review the Physician Quota Generation Model].

Before 1990, Chile showed fewer medical schools, six in total, increasing to 13 by 2000. From then on, there was an explosive increase, reaching 29 faculties or schools by 2024. Medical students increased from 1,816 in 2010 to 3,000 by 2024.

Exploration of Secondary Metabolites in (L.) Using Ethyl Acetate Extract and Its Antibacterial, Antioxidant, and Larvicidal Activities.

Improving the prebiotic activity and oxidative stability of carboxymethyl curdlan - quercetin conjugates stabilized Pickering emulsions for the colonic targeting delivery of curcumin.

The carboxymethyl curdlan-quercetin conjugate (CMCD-QUE) was synthesized to stabilize curcumin (CUR) -loaded Pickering emulsions. The physicochemical properties, antioxidant activity, and prebiotic activity of CMCD-QUE were investigated. The effects of different concentrations of CMCD-QUE on CUR-loaded emulsions were also explored.

Using peer narrative support to promote return to work for cancer survivors: a protocol study of action research.

Background: Chinese cancer survivors are not doing well in returning to work. Peer support, as an external coping resource to help cancer survivors return to work, brings together members of the lay community with similar stressors or problems for mutual support. Peer volunteers have not received systematic training, so inappropriate language in the support process can often cause secondary damage to both the peer and the cancer survivor.

Identification of the clinical and genetic characteristics of gliomas with gene fusions by integrated genomic and transcriptomic analysis.

The identification of oncogenic gene fusions in diffuse gliomas may serve as potential therapeutic targets and prognostic indicators, representing a novel strategy for treating gliomas consistent with the principles of personalized medicine. This study identified detectable oncogene fusions in glioma patients through an integrated analysis of genomic and transcriptomic data, which encompassed whole exon sequencing and next-generation RNA sequencing. In addition, this study also conducted a comparison of the genetic characteristics, tumor microenvironment, mutation burden and survival between glioma patients with or without gene fusions.

Biologic Therapy Is Associated With Improved Oncologic Outcomes in Crohn's Disease-Associated Colorectal Cancer.

Background: Patients with Crohn's disease face an elevated risk of colorectal cancer, in part due to underlying chronic inflammation. Biologic therapy is the mainstay of medical treatment; however, the impact of treatment on colorectal cancer-related outcomes remains unclear.

Objective: To investigate the association between prior exposure to biologic treatment and colorectal cancer-related outcomes in patients with underlying Crohn's disease.

Incidence and Risk Factors for Nonreversal of Stoma in Patients With Crohn's Disease: A Single-Center Study.

Background: Even in the biological era, permanent stoma is not uncommon in patients with Crohn's Disease.

Objective: This study aimed to investigate the incidence and risk factors of permanent stoma in Crohn's disease patients and provide clinical evidence for reducing this disabling outcome.

Design: Consecutive patients with Crohn's disease who underwent ostomies in the past decade were reviewed.

Quercetin inhibits platelet activation and ER-stress mediated autophagy in response to extracellular histone.

Background: Cellular histones are DNA-binding nuclear proteins involved in chromatin remodelling and regulation of gene expression. However, extracellular histones act as damage-associated molecular patterns (DAMPs) and contribute to multiorgan damage in conditions with sepsis and diseases with acute critical illnesses. Alongside, histones are associated with thrombocytopenia due to dysfunctional platelets that regulate hemostasis and thrombosis.

El trastorno por déficit de atención e hiperactividad (TDAH) ha sido tradicionalmente concebido como una condición privativa de la infancia. Sin embargo, una creciente evidencia sugiere que el TDAH persiste en la vida adulta, manifestándose de diversas maneras. A pesar de su prevalencia y de las significativas consecuencias en la vida cotidiana, el TDAH en adultos ha sido considerablemente subestimado y subdiagnosticado, lo que resulta en una carga sustancial tanto para los individuos afectados como para su entorno familiar y social.
