Prognostic impact of lymphovascular invasion in node-negative gastric cancer: a retrospective cohort study.

Background: Lymphovascular invasion (LVI) has been identified as a prognostic factor in various cancers, but its significance in node-negative gastric cancer remains unclear. Gastric cancer prognosis is notably affected by lymph node metastasis, with LVI potentially indicating metastatic spread.

Methods: A retrospective review was conducted on 5,699 patients who underwent curative radical gastrectomy for gastric cancer between 1989 and 2018.

Unraveling membrane protein localization and interactions in nanodiscs.

Nanodiscs, consisting of a lipid bilayer surrounded by membrane scaffold proteins (MSPs), are extensively used to study membrane proteins (MPs) because they provide a stable lipid environment. However, the precise mechanism governing MP behavior within the nanodisc remains elusive. Here, we examined the cryo-EM structures of various MPs reconstituted in nanodiscs from EMPIAR.

Anti-PD-L1 Antibody Fragment Linked to Tumor-Targeting Lipid Nanoparticle Can Eliminate Cancer and Its Metastasis via Photoimmunotherapy.

Effective cancer therapy aims to treat primary tumors and metastatic and recurrent cancer. Immune checkpoint blockade-mediated immunotherapy has shown promising effects against tumors; however, its efficacy in metastatic or recurrent cancer is limited. Here, based on the advantages of nanomedicine, lipid nanoparticles (LNPs) that can target tumors are synthesized for photothermal therapy (PTT) and immunotherapy to treat primary and metastatic recurrent cancer.

Molecular Complexity-Inspired Synthetic Strategies toward the Calyciphylline A-Type Alkaloids Himalensine A and Daphenylline.

In this report, we detail two distinct synthetic approaches to calyciphylline A-type alkaloids himalensine A and daphenylline, which are inspired by our analysis of the structural complexity of these compounds. Using MolComplex, a Python-based web application that we have developed, we quantified the structural complexity of all possible precursors resulting from one-bond retrosynthetic disconnections. This led to the identification of transannular bonds as especially simplifying to the molecular graph, and, based on this analysis, we pursued a total synthesis of himalensine A from macrocyclic intermediates with planned late-stage transannular ring formations.

P-type pilus PapG protein elicits toll-like receptor 2-mediated immune activation during cancer immunotherapy.

The immune activation ability of FimH, an adhesion protein in pili of Escherichia coli (E. coli), has been recently reported. However, studies on the immune activity of PapG, another major pili terminal protein, have not been well explored.

Photoimmunotherapy using indocyanine green-loaded Codium fragile polysaccharide and chitosan nanoparticles suppresses tumor growth and metastasis.

Metastasis and recurrence are the main challenges in cancer treatment. Among various therapeutic approaches, immunotherapy holds promise for preventing metastasis and recurrence. In this study, we evaluated the efficacy of treating primary cancer and blocking metastasis and recurrence with photo-immunotherapeutic nanoparticles, which were synthesized using two types of charged polysaccharides.

The aim of the study was to gather in-depth information on the individualized needs, lived experiences, and expectations of adults with DD by interviewing their parents.

Method: A total of 14 parents of adults with DD participated in one-on-one semistructured interviews.

Fucoidan from Durvillaea Antarctica enhances the anti-cancer effect of anti-PD-L1 antibody by activating dendritic cells and T cells.

Immune checkpoint inhibitors are showing groundbreaking results in tumor immunotherapy. However, there are cases where treatment efficiency is insufficient due to limitations in immune activity, and various trials to overcome this are being studied. In this study, we investigated the immune activation ability of fucoidan extracted from Durvillaea antarctica (FDA) and whether it can enhance the anti-cancer effects of immune checkpoint inhibitors.

Astrocytic autophagy plasticity modulates Aβ clearance and cognitive function in Alzheimer's disease.

Background: Astrocytes, one of the most resilient cells in the brain, transform into reactive astrocytes in response to toxic proteins such as amyloid beta (Aβ) in Alzheimer's disease (AD). However, reactive astrocyte-mediated non-cell autonomous neuropathological mechanism is not fully understood yet. We aimed our study to find out whether Aβ-induced proteotoxic stress affects the expression of autophagy genes and the modulation of autophagic flux in astrocytes, and if yes, how Aβ-induced autophagy-associated genes are involved Aβ clearance in astrocytes of animal model of AD.

Lipid-coated gold nanorods for photoimmunotherapy of primary breast cancer and the prevention of metastasis.

Nanomedicines hold promise for the treatment of various diseases. However, treating cancer metastasis remains highly challenging. In this study, we synthesized gold nanorods (AuNRs) containing (α-GC), an immune stimulator, for the treatment of primary cancer, metastasis, and recurrence of the cancer.

Peritoneal Washing Cytology Positivity in Gastric Cancer: Role of Lymph Node Metastasis as a Risk Factor.

Purpose: Peritoneal washing cytology (PWC) is a widely used diagnostic tool for detecting peritoneal metastasis of advanced gastric cancer. However, the prognosis of patients with positive PWC remains poor even after gastrectomy, and treatments vary among institutions and eras. In this study, we identified the clinical factors that can help predict cytology-positive (CY(+)) gastric cancer.

Regeneration of Non-Alcoholic Fatty Liver Cells Using Chimeric FGF21/HGFR: A Novel Therapeutic Approach.

Non-alcoholic fatty liver disease (NAFLD) has emerged as a significant liver ailment attributed to factors like obesity and diabetes. While ongoing research explores treatments for NAFLD, further investigation is imperative to address this escalating health concern. NAFLD manifests as hepatic steatosis, precipitating insulin resistance and metabolic syndrome.

Mechanistic Investigation, Wavelength-Dependent Reactivity, and Expanded Reactivity of -Aryl Azacycle Photomediated Ring Contractions.

Under mild blue-light irradiation, α-acylated saturated heterocycles undergo a photomediated one-atom ring contraction that extrudes a heteroatom from the cyclic core. However, for nitrogenous heterocycles, this powerful skeletal edit has been limited to substrates bearing electron-withdrawing substituents on nitrogen. Moreover, the mechanism and wavelength-dependent efficiency of this transformation have remained unclear.

Misinformation, Risk Perceptions, and Intention to Seek Information About Masks: The Moderating Roles of Gender and Reflective Judgment.

The current study has three main purposes: to examine 1) the impact of theory-driven corrective messages using individual vs. collective frames on information-seeking intention 2) the mediating role of risk perceptions and 3) the moderating role of reflection and gender. Our findings from a randomized experimental study and Hayes' moderated, moderated mediation model show collective frames were associated with high-risk perceptions among women, which in turn led to higher information seeking intention.

Multimodal Golden DNA Superstructures (GDSs) for Highly Efficient Photothermal Immunotherapy.

DNA-templated metallization has emerged as an efficient strategy for creating nanoscale-metal DNA hybrid structures with a desirable conformation and function. Despite the potential of DNA-metal hybrids, their use as combinatory therapeutic agents has rarely been examined. Herein, we present a simple approach for fabricating a multipurpose DNA superstructure that serves as an efficient photoimmunotherapy agent.

adhesion protein FimH exacerbates colitis via CD11bCD103 dendritic cell activation.
