Fast and accurate lung cancer subtype classication and localization based on Intraoperative frozen sections of lung adenocarcinoma.

Current lung cancer diagnostic techniques primarily focus on tissue subtype classification, yet remain inadequate in distinguishing pathological progression subtypes (particularly between adenocarcinomaand invasive adenocarcinoma) on frozen sections. This study develops a deep neural network-based auxiliary diagnostic system specifically for surgical frozen sections, aiming to reduce pathologists' diagnostic workload while improving differentiation accuracy.We developed an innovative deep learning system (FSG-TL Model) for lung adenocarcinoma frozen section analysis, combining multi-instance learning with EMA/SimAM/SE attention-enhanced ResSimAM_Hybrid model for classification.

Plasma Tailoring of NH-MIL-53 with Enhanced Fluorescence Emission for Simultaneous Detection of Multiple Heavy Metals in Water.

Indium, copper, and mercury are important raw materials in the electronics industry and often coexist in factory wastewater. Therefore, the development of a highly sensitive and selective method for the simultaneous detection of these heavy metal ions is of great significance for water quality monitoring and environmental protection. Herein, we report a NH-MIL-53 fluorescent probe for the simultaneous detection of trace In, Cu, and Hg in water.

NH Plasma Functionalization of UiO-66-NH for Highly Enhanced Selective Fluorescence Detection of U(VI) in Water.

Radioactive U(VI) in nuclear wastewater is a global environmental pollutant that poses a great threat to human health. Therefore, it is of great significance to develop a U(VI) sensor with desirable sensitivity and selectivity. Inspired by electron-donating group modification for enhancement of binding affinity toward U(VI), we report an amine group functionalization of UiO-66-NH, using a low-cost, environmentally friendly, and low-temperature NH plasma technique as a fluorescence switching nanoprobe for highly sensitive and selective detection of U(VI).

Long Non-Coding RNA HOXA11-AS Modulates Proliferation, Apoptosis, Metastasis and EMT in Cutaneous Melanoma Cells Partly via miR-152-3p/ITGA9 Axis.

Background: Long non-coding RNA homeobox A11 antisense RNA (HOXA11-AS) was showed to participate in the progression of different kinds of tumors, but the specific role of HOXA11-AS in cutaneous melanoma is not entirely unambiguous.

Methods: The levels of HOXA11-AS, microRNA-152-3p (miR-152-3p) and integrin alpha9 (ITGA9) were measured by quantitative real-time polymerase chain reaction (qRT-PCR). Cell proliferation was detected via 3-(4, 5-dimethylthiazol-2-y1)-2, 5-diphenyl tetrazolium bromide (MTT), and apoptosis was measured by flow cytometry.

Hydrothermal preparation of hierarchical ZIF-L nanostructures for enhanced CO capture.

A zeolitic imidazolate framework (ZIF-L) with hierarchical morphology was synthesized through hydrothermal method. The hierarchical product consists of ZIF-L leaves with length of several micrometers, width of 1 ∼ 2 μm and thickness of ∼300 nm cross connected symmetrically. It was found that the hydrothermal temperature is crucial for the formation of such hierarchical nanostructure.

Rapid Construction of ZnO@ZIF-8 Heterostructures with Size-Selective Photocatalysis Properties.

To selectively remove heavy metal from dye solution, inspired by the unique pore structure of ZIF-8, we developed a synthetic strategy for rapid construction of ZnO@ZIF-8 heterostructure photocatalyst for selective reduction of Cr(VI) between Cr(VI) and methylene blue (MB). In particular, ZnO@ZIF-8 core-shell heterostructures were prepared by in situ ZIF-8 crystal growth using ZnO colloidal spheres as template and zinc source within 8-60 min. The shell of the resulting ZnO@ZIF-8 core-shell heterostructure with a uniform thickness of around 30 nm is composed of ZIF-8 crystal polyhedrons.

Morphological control of multihollow polymer latex particles through a controlled phase separation in the seeded emulsion polymerization.

In this work, we first reported that the phase separation can take place both inside and outside of a multihollow-structured cross-linked seed microspheres swollen by styrene monomers in water during the radiation-induced seeded emulsion polymerization. The phase separation process in these two opposite directions will determine the morphology of final latex particles. First, sulfonated cross-linked polystyrene (SCPS) seed microspheres were swollen by styrene in water.

[Discovery and genetic analysis of blue-eyed mutant in the white rex rabbits].

Using cross, backcross, and full-sib mating experiments, allelism test was conducted to study the genetic mechanism of blue-eyed mutant of the white rex rabbits originated from the F1 generation from the cross American White rex rabbits(♂) × Chinchilla meat rabbits(♀). The study showed that the reason for the blue-eyed mutant of the white rex rabbits was a recessive mutation in Vienna locus. When the V locus was homozygous for the recessive v gene, it was recessive epistatic to other loci (including A, B, C, D, and E), which also controlled the coat color.

Genetic variation in the promoter of DNMT3B is associated with the risk of colorectal cancer.

Purpose: DNA methyltransferase-3B (DNMT3B) plays an important role in the generation of aberrant methylation in carcinogenesis. Polymorphisms of the DNMT3B gene may influence DNMT3B enzyme activity on DNA methylation, thereby modulating the susceptibility to colorectal cancer (CRC).

Methods: The polymorphisms in the promoter region of the DNMT3B gene [-149C>T (rs2424913) and -579G>T (rs1569686)] were detected by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP), and a total of 544 CRC patients and 533 age- and sex-matched healthy controls were enrolled in the case-control study.

Polymorphisms in interleukin-1B (IL-1B) and interleukin 1 receptor antagonist (IL-1RN) genes associate with gastric cancer risk in the Chinese population.

Background: Gastric cancer is one of the most common malignancies afflicting the Chinese population. Polymorphisms in interleukin-1B (IL-1B) and interleukin-1 receptor antagonist (IL-1RN) genes have been associated with increased gastric cancer risk.

Aims: A case-control study enrolled 392 gastric cancer patients and 508 healthy were carried out to investigate the association between polymorphisms in IL-1B and IL-1RN and gastric cancer risk.

Inhibition of CD147 gene expression via RNA interference reduces tumor cell invasion, tumorigenicity and increases chemosensitivity to cisplatin in laryngeal carcinoma Hep2 cells.

CD147, also named extracelluar matrix metalloproteinase inducer (EMMPRIN), is a member of the immunoglobulin family and a glycoprotein enriched on the surface of tumor cells, which promotes invasion, metastasis, growth and survival of malignant cells, and is known to confer resistance to some chemotherapeutic drugs. To determine the possible role of CD147 in the invasive properties of laryngeal carcinoma, we used an RNA interference approach to silence CD147 expression in the Hep2 cell line at high levels of CD147 expression. Our results showed that CD147 expression was significantly impeded at both mRNA and protein levels, which resulted in a decrease of the Hep2 invasion activity in vitro and tumorigenicity in nude mice.

Association between polymorphisms in RAPGEF1, TP53, NRF1 and type 2 diabetes in Chinese Han population.

Type 2 diabetes is a common complex disorder with environmental and genetic components. The aim of the present study was to investigate the association between the polymorphisms of RAPGEF1, TP53 and NRF1 and the risk of type 2 diabetes in the Chinese Han population. We genotyped rs11243444 (RAPGEF1), rs1042522 (TP53) and rs1882095 (NRF1) in a case-control study, including 273 type 2 diabetes and 247 healthy controls.

Targeted tumor gene therapy based on loss of IGF2 imprinting.

Loss of imprinting (LOI) of the insulin-like growth factor 2 gene (IGF2) is one of the most common epigenetic abnormalities seen in human neoplasms. LOI may be associated with the lack of Zinc-finger DNA binding protein CTCF-mediated enhancer insulation, presumably due to the gain of methylation on the maternal allele of the differentially methylated domain (DMD) of the imprinting control region. This results in an interaction between the IGF2 promoters and enhancers; and IGF2 is produced from both alleles.

RNAi-mediated silencing of CD147 inhibits tumor cell proliferation, invasion and increases chemosensitivity to cisplatin in SGC7901 cells in vitro.

Background: CD147 is a widely distributed cell surface glycoprotein that belongs to the Ig superfamily. CD147 has been implicated in numerous physiological and pathological activities. Enriched on the surface of many tumor cells, CD147 promotes tumor growth, invasion, metastasis and angiogenesis and confers resistance to some chemotherapeutic drugs.
