Sensitive detection of Hg(II) on MoS/NiS based on interfacial engineering to accelerate the Ni/Ni cycle: Identification the role of atomic-level heterojunction-induced electron transfer in electroanalysis.

The valence change of transition metal ions in nanomaterials can highly enhance the electrochemical detection performance toward heavy metal ions (HMIs), and how to further promote the valence change calls enormous concerns in electroanalysis. In this work, an interfacial engineering that combing the MoS and NiS together to form the MoS/NiS complex is proposed. The density functional theory (DFT) results reveals that the novel atomic-level heterojunction between MoS and NiS will build an internal electric field (IEF), which leads to an enhanced conductivity and valence change behavior of Ni atoms in MoS/NiS complex, resulting in a superior detection performance.

Young patient with a giant gastric bronchogenic cyst: A case report and review of literature.

Background: Gastric bronchogenic cysts (BCs) are extremely rare cystic masses caused by abnormal development of the respiratory system during the embryonic period. Gastric bronchial cysts are rare lesions that were first reported in 1956; as of 2023, only 33 cases are available in the PubMed online database. BCs usually have no clinical symptoms in the early stage, and imaging findings also lack specificity.

Is Pathologic Complete Response the Surrogate in Primary Gastric Angiosarcoma Undergoing Doxorubicin-Based Neoadjuvant Chemotherapy? A Case Report.

Introduction: Angiosarcoma is a malignant tumor with low incidence. Especially in the advanced tumors, there is still a lack of knowledge of evidence-based medicine.

Case Presentation: We report a case of a 55-year-old woman with abdominal pain of 2 months of duration, which had increased in severity for 2 weeks prior to the presentation.

miR‑4262 inhibits colon cancer cell proliferation via targeting of GALNT4.

MicroRNAs (miRs) have been demonstrated to be important in the establishment and progression of colon cancer. However the underlying molecular mechanisms remain to be fully elucidated. Polypeptide N‑acetylgalactosaminyltransferase4 (GALNT4) participates in numerous cellular processes, including tumorigenesis.

[Clinical study of the predictors to neoadjuvant chemotherapy in patients with advanced gastric cancer].

Objective: To investigate the predictive value of seven gastric cancer-associated factors on neoadjuvant chemotherapy in patients with advanced gastric cancer.

Methods: Expressions of C-met, EGFR, HER2, Ki-67, MMP7, P53 and TOPOII were detected by immunohistochemistry in gastric cancer tissues of 53 cases before and after mFOLFOX7 neoadjuvant chemotherapy. Chemotherapy efficacy was evaluated according to RECIST 1.

[A clinical study of paclitaxel combined with FOLFOX4 regimen as neoadjuvant chemotherapy for advanced gastric cancer].

Objective: To evaluate the clinical efficacy and the toxicity of neoadjuvant chemotherapy with paclitaxel and FOLFOX4 (5-fluorouracil/leucovorin combined and oxaliplatin) regimen for advanced gastric cancer.

Methods: Seventy-eight patients with cTNM stage III or IV (M0) gastric cancer were enrolled and 39 were randomized into the treatment arm (n=39, paclitaxel combined with FOLFOX4 regimen neoadjuvant chemotherapy every two weeks in each cycle) and control group (n=39). Clinical response was evaluated with RECIST criteria after 3 cycles.

[Landscape pattern and its dynamics in typical oasis-desert transitional zone of Minqin Region in 1960-2005].

By using ERDAS and GIS techniques, a systematic analysis was made on the landscape pattern and its dynamics in typical oasis-desert transitional zone of Minqin Region in 1960-2005. Forest land and cultivated land were the dominant factors leading to the landscape change. During the research period, oasis expanded toward the periphery by 2-3 km, and the transitional zone moved toward desert, with its width increased from 4 km in 1960 to about 9 km in 1987 and decreased rapidly then.

Environmental characteristics of sandstorm of Minqin Oasis in China for recent 50 years.

The purpose of this present study is to investigate the frequency and variation of sandstorm in Minqin Oasis. Using daily observational data of sandstorm and other meteorologic data from 1954 to 2000, we have illuminated the relationship between sandstorm, meteorological parameters and human activities. The results of the analysis show that the highest frequency of sandstorms occurrence and their duration mainly focus on March, April and May, especially in April.
