Rectal cancer is one of the most prevalent malignancies worldwide, and the introduction of an endoscopic submucosal dissection (ESD) has offered minimally invasive management for early colorectal cancers. On the other hand, a post-ESD pathological examination showed that the risk of lymph node metastasis increases with deep submucosal (SM) invasion, positive lymphovascular invasion, grade 2/3 tumor budding, and certain histological types. An intestinal resection with a lymph node dissection is recommended in these cases, and chemoradiotherapy (CRT) is also effective adjuvant therapy.

Article Synopsis
  • The study aimed to evaluate how eye movements impact the progression of primary open-angle glaucoma by analyzing biomechanical changes in the optic nerve head (ONH).
  • Researchers created a virtual ONH model for 118 glaucoma patients, looking at factors like axial length and optic disc radius, and simulated how these changed under different eye movements.
  • Results showed that patients with progression of glaucoma experienced greater stress and asymmetric stress distribution in the ONH during eye rotation, particularly linked to optic disc size and cup deepening.

Article Synopsis
  • The study focuses on VacA, a toxin from Helicobacter pylori, investigating its harmful effects on specific types of stomach cells, particularly how it damages mitochondria and affects cell function.
  • Researchers used human gastric organoids (hAGOs) and tissue samples from infected patients to demonstrate that VacA leads to significant mitochondrial damage and reduced energy production, which weakens the stomach's protective barrier.
  • The study identified a potential treatment, MLN8054, that can repair VacA-induced mitochondrial damage and restore the integrity of gastric cells, highlighting hAGOs as an effective model for testing new drugs against VacA-related diseases.

Nanofiber (NF) membrane systems that can provide cascade catalytic reaction and ferroptosis induction were developed for oral cancer therapy. Glucose oxidase (GOx) and aminoferrocene (AF) were introduced into the NF system for glucose deprivation/HO generation and OH radical generation, respectively. GOx offers starvation therapy and AF (including iron) provides chemodynamic therapy/ferroptosis for combating oral cancer.

This paper introduces catheter-directed intravascular casting hydrogels for transarterial chemo/starvation/chemodynamic embolization (TACSCE) therapy of hepatocellular carcinoma (HCC). Comprising Mn ion-crosslinked hyaluronic acid-dopamine (HD) with glucose oxidase (for glucose decomposition to HO in starvation therapy), doxorubicin (for chemotherapy), and iopamidol (for X-ray imaging), these hydrogels are fabricated for transarterial embolization therapy guided by X-ray fluoroscopy. Mn (from MnO) demonstrates strong coordination with the catechol group of HD, providing hypoxia relief through O generation and cellular glutathione (GSH) consumption, compared to the OH radical generation potential of Mn.

Article Synopsis
  • Scientists came up with the terms "onychofibroblast" (nail-specific cells) and "onychodermis" (nail-specific skin) to describe special parts of the nail that are different from regular skin.*
  • Recent research shows that these nail cells and skin areas are important for how nails form and can affect nail health when they have problems.*
  • They found that certain genes in the onychofibroblasts help with nail growth and that tumors related to nails come from these special cells.*

Purpose: In case of a nuclear accident, individuals with high-dose radiation exposure (>1-2 Gy) should be rapidly identified. While ferredoxin reductase (FDXR) was recently suggested as a radiation-responsive gene, the use of a single gene biomarker limits radiation dose assessment. To overcome this limitation, we sought to identify reliable radiation-responsive gene biomarkers.

Optogenetic techniques combine optics and genetics to enable cell-specific targeting and precise spatiotemporal control of excitable cells, and they are increasingly being employed. One of the most significant advantages of the optogenetic approach is that it allows for the modulation of nearby cells or circuits with millisecond precision, enabling researchers to gain a better understanding of the complex nervous system. Furthermore, optogenetic neuron activation permits the regulation of information processing in the brain, including synaptic activity and transmission, and also promotes nerve structure development.

Indocyanine green (ICG), glucose oxidase (GOx), and copper(II) sulfate (Cu)-installed hybrid gel based on organic nanorod (cellulose nanocrystal [CNC]) and inorganic nanodisk (Laponite [LAP]) was developed to perform a combination of starvation therapy (ST), chemodynamic therapy (CDT), and photothermal therapy (PTT) for localized cancers. A hybrid CNC/LAP network with a nematic phase was designed to enable instant gelation, controlled viscoelasticity, syringe injectability, and longer in vivo retention. Moreover, ICG was introduced into the CNC/LAP gel system to induce hyperthermia of tumor tissue, amplifying the CDT effect; GOx was used for glucose deprivation (related to the Warburg effect); and Cu was introduced for hydroxyl radical generation (based on Fenton-like chemistry) and cellular glutathione (GSH) degradation in cancer cells.
