Real-Time Monitoring of Volatile Organic Compound-Mediated Plant Intercommunication Using Surface-Enhanced Raman Scattering Nanosensor.

Plants communicate through volatile organic compounds (VOCs), but real-time monitoring of VOCs for plant intercommunication is not practically possible yet. A nanobionic VOC sensor plant is created to study VOC-mediated plant intercommunication by incorporating surface-enhanced Raman scattering (SERS) nanosensors into a living plant. This sensor allows real-time monitoring of VOC with a sensitivity down to the parts per trillion level.

Urinary Catheter Management.

Family physicians often treat patients who require urinary management with the use of external urinary devices, clean intermittent catheterization, or indwelling urinary catheterization. External urinary devices are indicated for urinary incontinence (postvoid residual less than 300 mL), urine volume measurement for hospitalized patients, nonsterile urine diagnostic testing, improved comfort for patients in hospice or palliative care, and fall prevention for high-risk patients. Indwelling urinary catheterization is indicated for severe urinary retention or bladder outlet obstruction; wound healing in the sacrum, buttocks, or perineal area; prolonged immobilization; and as a palliative measure for patients who are terminally ill.

However, the impact of grade 3 endometrial cancer on nodal involvement, recurrence, and prognosis within this specific subgroup remains unclear. Therefore, in this study, we aimed to investigate the prognosis, patterns of metastasis, and recurrence in a subgroup of females with grade 3 early-stage low-risk endometrioid endometrial cancer.

Prediction of final pathology depending on preoperative myometrial invasion and grade assessment in low-risk endometrial cancer patients: A Korean Gynecologic Oncology Group ancillary study.

Objectives: Fertility-sparing treatment (FST) might be considered an option for reproductive patients with low-risk endometrial cancer (EC). On the other hand, the matching rates between preoperative assessment and postoperative pathology in low-risk EC patients are not high enough. We aimed to predict the postoperative pathology depending on preoperative myometrial invasion (MI) and grade in low-risk EC patients to help extend the current criteria for FST.

Chiral-Induced Surface-Enhanced Raman Optical Activity on a Single-Particle Substrate.

Surface-enhanced Raman optical activity (SEROA) is a promising method for analyzing chiral molecules' molecular chirality and structural changes. However, conventional SEROA measurements face challenges related to substrate stability, signal uniformity, and interference from electronic circular dichroism (ECD). Therefore, in this study, we present a uniform and stable substrate for SEROA measurements by utilizing Au nanoparticles on the Au nanofilm structure to confine hotspots to the film-particle junctions and minimize ECD interference.

SERS detection of dopamine using metal-chelated Ag nanoshell.

As the concentrations of different neurotransmitters can indicate the presence of certain disorders affecting brain functions, quantitative analyses of neurotransmitters have attracted increasing attention in various fields. Surface-enhanced Raman scattering (SERS) spectroscopy is an outstanding spectroscopic analytical tool that enables detection at the single molecule level with high specificity. As local field enhancement of surface plasmon is effective within nanometers, active interaction between SERS-active noble metals (gold and silver) and analyte molecules enhances the molecular detection capacity of SERS.

Vaginal microbiota analysis, including microbial diversity and specific bacterial abundances, was performed using 16S rRNA gene sequencing.

Therapeutic effects of surgical debulking of metastatic lymph nodes in cervical cancer IIICr: a trial protocol for a phase III, multicenter, randomized controlled study (KGOG1047/DEBULK trial).

Background: Bulky or multiple lymph node (LN) metastases are associated with poor prognosis in cervical cancer, and the size or number of LN metastases is not yet reflected in the staging system and therapeutic strategy. Although the therapeutic effects of surgical resection of bulky LNs before standard treatment have been reported in several retrospective studies, well-planned randomized clinical studies are lacking. Therefore, the aim of the Korean Gynecologic Oncology Group (KGOG) 1047/DEBULK trial is to investigate whether the debulking surgery of bulky or multiple LNs prior to concurrent chemoradiation therapy (CCRT) improves the survival rate of patients with cervical cancer IIICr diagnosed by imaging tests.

Enhancement of the signal-to-noise ratio in fiber-optics based SERS detection by rough-cutting the end surface.

Fiber-optics based surface-enhanced Raman scattering (FO-SERS) has an unique advantage of being able to remotely detect analyte molecules because the fiber length can be adjusted as desired. However, the Raman signal of the fiber-optic material is so strong that it is an important challenge in utilization of optical fiber for remote SERS sensing. In this study, we found that the background noise signal was greatly reduced by ca.

Vapours from plant essential oils to manage tomato grey mould caused by Botrytiscinerea.

Tomato grey mould has been a great concern during tomato production. The in vitro antifungal activity of vapours emitted from four plant essential oils (EOs) (cinnamon oil, fennel oil, origanum oil, and thyme oil) were evaluated during in vitro conidial germination and mycelial growth of Botrytis cinerea, the causal agent of grey mould. Cinnamon oil vapour was the most effective in suppressing conidial germination, whereas the four EOs showed similar activities regarding inhibiting mycelial growth in dose-dependent manners.

We investigated LAG-3 expression and its prognostic value in patients with surgically treated clear cell renal cell carcinoma (RCC) and correlated LAG-3 expression with programmed cell death ligand 1(PD-L1).

Methods: We evaluated LAG-3 and PD-L1 expression using immunohistochemistry on tissue microarrays incorporating 134 primary excision specimens of clear cell RCC (ccRCC).

VSIG4-expressing tumor-associated macrophages impair anti-tumor immunity.

VSIG4, a newly identified co-inhibitory molecule belonging to the B7-related family, is exclusively expressed on tissue-resident macrophages and is involved in the suppression of T cell proliferation and cytokine production. We sought to characterize the role of VSIG4 in anti-tumor immunity in the tumor microenvironment, focusing on VSIG4-expressing tumor-associated macrophages (TAMs). We found that VSIG4-expressing TAMs negatively regulated antigen-specific T cell proliferation and cytokine production through direct inhibition via cell cycle arrest, but not apoptosis, as well as through their arginase 1 activity.
