Cadmium (Cd), a highly toxic non-essential heavy metal, disrupts cellular processes even at low concentrations. The current studies of Cd stress rely on whole-plant models with prolonged treatments, obscuring early response signals. Tobacco, a typical model plant, lacks protoplast-level investigations under Cd stress.

Background: The incidence of endometriosis is rising, particularly among younger populations, yet current diagnostic and therapeutic approaches remain limited. This highlights the urgent need for novel diagnostic tools and effective treatments. Recent studies have shown that intestinal and reproductive tract bacterial dysbiosis is closely associated with the development of endometriosis and plays a key role in the regulation of estrogen metabolism.

P53 protein is one of the main cancer biomarkers, and its detection is of great significance for early diagnosis and treatment of various cancers such as breast, rectal, and lung cancer. In this paper, a cascaded tapered seven-core fiber (CTSCF) biosensor is proposed for rapid detection of p53 protein. The experiment results show that the proposed CTSCF biosensor can effectively detect the p53 protein at concentrations of 0.

Scopoletin is a kind of coumarins, which play essential roles in plant development and human health. SHN1/WIN1 has been shown to promote polyphenols biosynthesis in tobacco, but the roles of its homologous protein SHN3 in regulating secondary metabolite accumulation are still unclear. In this study, we identified a new SHINE-type transcription factor NtSHN3 from N.

Background: Gastric carcinoma with coexisting exocrine and neuroendocrine components (GC-EN) is a rare and aggressive subtype of gastric cancer that presents unique challenges in diagnosis, treatment, and prognosis. The effect of lymph node metastasis with different components on survival in patients with GC-EN is unknown.

Patients And Methods: This retrospective study included 98 patients diagnosed with GC-EN at the China National Cancer Center between January 2004 and December 2020.

Despite the progress of treatment in gastric cancer (GC), the overall outcomes remain poor in patients with advanced diseases, underscoring the urgency to develop more effective treatment strategies. BH3-mimetic drugs, which inhibit the pro-survival BCL2 family proteins, have demonstrated great therapeutic potential in cancer therapy. Although previous studies have implicated a role of targeting the cell survival pathway in GC, the contribution of different pro-survival BCL2 family proteins in promoting survival and mediating resistance to current standard therapies in GC remains unclear.

Objectives: This study aims to assess the association between adjuvant radiotherapy and the development of second primary malignancies (SPMs) and identify its determinants in patients who have undergone surgical treatment for gastric cancer.

Design: Retrospective cohort study using the Surveillance, Epidemiology and End Results (SEER) database.

Setting: Cohorts (18 registries, 2000-2018, from SEER) were screened for any malignancy that developed after sufficient latency from diagnosis of surgically treated non-metastatic gastric cancer.

Article Synopsis
  • The study highlights the impressive lithium ionic conductivity achieved using graphene oxide laminar membranes, which significantly exceeds that of traditional lithium-ion electrolytes.
  • At 170 mS cm, the nanoconfined lithium electrolyte demonstrates extraordinary performance, maintaining useful conductivity even at extremely low temperatures.
  • The findings suggest that the enhanced ion transport is due to unique layer distribution effects in the nanochannels, potentially revolutionizing energy storage technologies by integrating these channels into lithium battery components.

While ultrasonography effectively diagnoses Hashimoto's thyroiditis (HT), exploring its transcriptomic landscape could reveal valuable insights into disease mechanisms. This study aimed to identify HT-associated RNA signatures and investigate their potential for enhanced molecular characterization. Samples comprising 31 HT patients and 30 healthy controls underwent RNA sequencing of peripheral blood.

The utilization of CO foam gel fracturing fluid offers several significant advantages, including minimal reservoir damage, reduced water consumption during application, enhanced cleaning efficiency, and additional beneficial properties. However, several current CO foam gel fracturing fluid systems face challenges, such as complex preparation processes and insufficient viscosity, which limit their proppant transport capacity. To address these issues, this work develops a novel CO foam gel fracturing fluid system characterized by simple preparation and robust foam stability.

Utilizing drug-loaded hydrogels to restore nerve conductivity emerges as a promising strategy in the treatment of spinal cord injury (SCI). However, many of these hydrogels fail to deliver drugs on demand according to the dynamic SCI pathological features, resulting in poor functional recovery. Inspired by the post-SCI microenvironments, here we report a time-sequential and controllable drug delivery strategy using an injectable hydrogel responsive to reactive oxygen species (ROS) and matrix metalloproteinases (MMPs).

Iron-based materials have demonstrated significant efficacy in catalyzing hydrogen peroxide (HO) for the removal of antibiotics from aquatic environments. Green rust (GR), a hybrid valence state iron-based catalyst, was synthesized. By exploiting the catalytic properties of glucose oxidase (GOx) to generate HO from glucose (Glu), a GR-GOx/Glu system for the removal of recalcitrant organic compound 4-chlorophenol (4-CP) was constructed.

Background: To explore the clinical and chest CT features of Talaromycosis marneffei (TSM), and to compare the differences between anti‑IFN‑γ autoantibodies‑positive and HIV-positive cases.

Methods: Clinical data and chest CT images of 54 HIV-negative patients with Talaromyces marneffei (TM) infection and positive anti-interferon-γ (anti-IFN-γ) autoantibody were retrospectively analyzed. Ninety-three HIV-positive patients with TM infection during the same period were included as controls.

  • The study aimed to develop a dual-energy CT (DECT)-based nomogram to predict how well patients with advanced non-small cell lung cancer (NSCLC) respond to non-surgical treatments.
  • Pre-treatment DECT images from 98 NSCLC patients were analyzed, utilizing radiomics metrics and logistic regression to create and evaluate different predictive models.
  • The final clinical-radiomics nomogram demonstrated strong predictive accuracy, outperforming other models, and effectively integrated DECT features with clinical information to assess treatment response.

Background: Perioperative chemotherapy is the standard treatment modality for locally advanced gastric cancer. However, the efficacy and indication of adjuvant chemotherapy in patients who have already received neoadjuvant chemotherapy remain unclear. This study aims to explore the association between adjuvant chemotherapy with patient prognosis in those who have received neoadjuvant chemotherapy plus D2 gastrectomy in a real-world setting, and whether this association is affected by the duration of neoadjuvant treatment.

Squamous cell carcinoma antigen (SCCA) is one of the most commonly detected cancer biomarkers for a variety of cancers. In this paper, a microfiber ring laser biosensor with a graphene oxide linking layer for SCCA detection was proposed and experimentally demonstrated. SCCA antibody immobilized on graphene oxide surface binds specifically to SCCA, and induces refractive index variation over the surface of the microfiber biosensor, which leads to a wavelength shift of the microfiber ring laser biosensor.
