Characteristics of debris flow development in Daxilada watershed and its hazard analysis on Lexi Expressway.

The occurrence of frequent debris flow catastrophes in the mountainous regions of southwest China has necessitated the inclusion of debris flow disaster analysis and prevention as an essential component in the planning and construction of mountainous roadways. Daxilada watershed is located in the south of Mabian Yi Zuzizhixian, Leshan City, Sichuan Province, and the proposed Leshan-Xichang Expressway (Lexi Expressway) will pass through the upper reaches of Daxilada watershed. It is essential to consider that the presence of debris flows within the Daxilada watershed could have detrimental effects on the construction and functionality of the proposed Luoshanxi Bridge.

Evaluation of highway debris flow hazard based on geomorphic evolution theory coupled with material response rate.

Assessments of highway feasibility frequently lack the detailed data and geological information necessary to conduct hazard evaluations of debris flows. This study discusses the processes of debris flow development when regional rainfall meets the critical level required for debris flow initiation. It utilizes geomorphic evolution theory and establishes a regional risk assessment matrix for debris flow by combining information about gullies and source sensitivity.

Parent Artery Chronical Occlusion after Endovascular Treatment of a Unruptured "True" Posterior Communicating Artery Aneurysm.

A case of a patient with a true large unruptured posterior communicating artery (PCoA) aneurysm in a distal segment of PCoA, who was treated by interventional therapy via an ipsilateral occlusion of the internal carotid artery (ICA), is reported. Although the treatment went very well and the patient recovered very well, angiography 6 months after the operation showed that left PCoA had occluded and the aneurysm disappeared. The temporary recanalization of occluded ophthalmic segment of ICA can be a pathway for interventional therapy.

Case report: Conservative treatment for fertility preservation in a woman with hemoperitoneum due to an invasive mole.

Background: Invasive moles are a subtype of gestational trophoblastic neoplasia (GTN) that usually develops after hydatidiform molar pregnancies. Uterine rupture in high-risk GTN is a rare and potentially catastrophic event. The treatment of invasive mole perforation with uterine rupture is particularly challenging in young women who desire fertility preservation.

Tumour-derived exosomal piR-25783 promotes omental metastasis of ovarian carcinoma by inducing the fibroblast to myofibroblast transition.

Ovarian carcinoma inherently possesses a distinct metastatic organotropism for the adipose-rich omentum, contributing to disease progression. Although the premetastatic microenvironment (PMM) has been known to often play a prometastatic role during the process, incomplete mechanistic insight into PMM formation has prevented its therapeutic targeting. Omental fibroblasts can be activated by tumour cells to differentiate into myofibroblasts, termed the fibroblast-to-myofibroblast transition (FMT), which, in turn, enhances cancer aggressiveness.

Analysis of the evolution trends and influential factors of bankfull discharge in the Lower Yellow River.

After the Xiaolangdi Reservoir (XLDR) was put into operation, new water and sediment conditions have improved the silting condition of the Lower Yellow River (LYR), but against this background, the flow capacity of the LYR has become more complex. In this research, the measured water and sediment data of seven hydrological stations in the LYR from 1950 to 2020 were systematically collated. The evolution trend and development period of the bankfull discharge in this area were studied based on the wavelet analysis method, and the main factors influencing the evolution of the bankfull discharge were explored.

Here, we would like to share our experience in the treatment of a locally advanced primary embryonal rhabdomyosarcoma of cervix in a 39-year-old female.

Case Summary: The patient was admitted with symptoms of intermenstrual bleeding and postcoital bleeding for six months.

A meta-analysis of survival after minimally invasive radical hysterectomy versus abdominal radical hysterectomy in cervical cancer: center-associated factors matter.

Purpose: To explore the possible factors that contributed to the poor performance of minimally invasive surgery (MIS) versus abdominal surgery regarding progression-free survival (PFS) and overall survival (OS) in cervical cancer.

Methods: MEDLINE, EMBASE, Cochrane Library and Web of Science were searched (January 2000 to April 2021). Study selection was performed by two researchers to include studies reported oncological safety.

Tumor cell-derived exosomes deliver TIE2 protein to macrophages to promote angiogenesis in cervical cancer.

Tyrosine kinase with immunoglobulin and epidermal growth factor homology domains 2 (TIE2)-expressing macrophages (TEMs) are an angiogenesis-promoting subset of tumor-associated macrophages that have been demonstrated to be increased in solid tumors and associated with the progression of cervical cancer. However, the induction mechanism of TEMs remains unclear. Here, based on multicolor immunofluorescence of 58 cervical cancer tissues and the GEPIA database, we found that TEMs were increased in TIE2-high cervical cancer and related to shorter survival.

FABP4 is an independent risk factor for lymph node metastasis and poor prognosis in patients with cervical cancer.

Background: Pelvic lymph node metastasis (LNM) is a crucial independent prognostic factor in cervical cancer (CCa) and serves as an indicator for radiation therapy as the primary or an adjuvant treatment option. However, preoperative diagnosis of LNM remains challenging. Thus, we aimed to identify biomarkers of LNM in patients with presumed early-stage CCa.

Monitoring the Spatiotemporal Difference in Glacier Elevation on Bogda Mountain from 2000 to 2017.

The difference in glacier surface elevation is a sensitive indicator of climate change and is also important for disaster warning and water supply. In this paper, 25 glaciers on Bogda Mountain, in the eastern Tianshan Mountains, are selected as the study object as they are typical of glaciers in arid or semi-arid areas with importance for water supply. The Repeat Orbit Interferometry (ROI) method is used to survey the surface elevation of these glaciers using Sentinel-1A Radar data from 2017.

Deformation Time Series and Driving-Force Analysis of Glaciers in the Eastern Tienshan Mountains Using the SBAS InSAR Method.

Glacier melting is one of the important causes of glacier morphology change and can provide basic parameters for calculating glacier volume change and glacier mass balance, which, in turn, is important for evaluating water resources. However, it is difficult to obtain large-scale time series of glacier changes due to the cloudy and foggy conditions which are typical of mountain areas. Gravity-measuring satellites and laser altimetry satellites can monitor changes in glacier volume over a wide area, while synthetic-aperture radar satellites can monitoring glacier morphology with a high spatial and temporal resolution.

Methods: One special retrospective study was conducted with more than 400 patients involved in laparoscopic procedure.

Results: Our results suggest that estimated blood loss and transfusion requirements were significantly lower in the LRH group.

CXCR3 is a prognostic marker and a potential target for patients with solid tumors: a meta-analysis.

Objective: To deeply verify the clinical significance of CXCR3 in prediction of cancer patients' prognosis.

Data Sources: We performed a meta-analysis including 12 studies searched from PubMed, Web of Science, Embase, and Cochrane databases. A total of 1,751 patients were used to analyze the association between CXCR3 and patients' prognosis, based on either overall survival or time to tumor progression.

Role of HER family members in predicting prognoses in epithelial ovarian cancer: a meta-analysis.

Aims And Background: Human epidermal receptor (HER) family receptors are commonly overexpressed in various human tumors, and their overexpression is thought to play a critical role in tumor progression. The aim of this meta-analysis was to evaluate the prognostic significance of HER family members in epithelial ovarian cancer (EOC).

Methods: Relevant studies published between January 1, 1980, and April 24, 2013, that evaluated the associations of HER family members with overall survival (OS), progression-free survival (PFS), response to platinum-based chemotherapy, lymph node metastasis, or ascites in EOC were identified via searches of PubMed and EMBASE.

The role of the PTEN/PI3K/Akt pathway on prognosis in epithelial ovarian cancer: a meta-analysis.

The PTEN/PI3K/Akt signaling pathway, a key player in mediating apoptosis, metabolism, cell proliferation, and cell growth, is frequently dysregulated in many cancers. However, the pathway's prognostic impact in epithelial ovarian cancer (EOC) is still inconsistent. We performed a meta-analysis based on individual study outcomes to more precisely evaluate its clinical significance in EOC patients.

Tumor-associated macrophages induce lymphangiogenesis in cervical cancer via interaction with tumor cells.

Our studies were conducted to investigate the clinical and functional significance of tumor-associated macrophages (TAMs) in cervical tumor lymphatic metastasis. We found that the increase in macrophages in tumor stroma is significantly associated with lymphatic metastasis (p = 0.017), through performing immunohistochemical staining in 111 cervical samples (55 invasive squamous carcinomas of uterine cervix, 27 cervical intraepithelial neoplasms III, and 29 normal cervix).

EZH2 participates in malignant biological behavior of epithelial ovarian cancer through regulating the expression of BRCA1.

Aberrant overexpression of the enhancer of zeste homolog 2 (EZH2), a histone methyltransferase inhibiting targets expression via epigenetic mechanisms, is associated with an invasive phenotype and drug resistance in ovarian cancer. Breast cancer 1 (BRCA1) gene is a well-recognized tumor suppressor, whose downregulation plays a key role in the development of ovarian cancer. In the present study, we found depletion of EZH2 increased BRCA1 protein expression and promoted its nuclear translocation, but decreased BRCA1 mRNA expression.

Cancer-associated fibroblasts enhance the migration ability of ovarian cancer cells by increasing EZH2 expression.

The tumor microenvironment is thought to affect malignant transformation and tumor progression. The histone methyltransferase, enhancer of zeste homologue 2 (EZH2), has recently been suggested to play a critical role in the tumorigenesis of several types of human cancer. The aim of this study was to investigate the effects of cancer-associated fibroblasts (CAFs) on the expression of EZH2 and the migration ability of ovarian cancer cells, in order to explore the link between the tumor microenvironment and epigenetic regulation.

Prognostic significance of several biomarkers in epithelial ovarian cancer: a meta-analysis of published studies.

Objective: Abnormal expression of several biomarkers might predict disease prognosis and response to chemotherapy in patients with epithelial ovarian cancer (EOC). However, the published data are inconsistent.

Methods: Eligible studies that investigated the association between survival or response to platinum-based chemotherapy in EOC and the expression status of Bcl-2, EGFR, GST, LRP, p16, p21, P-gp and TNF-α were identified by an electronic search of PubMed and Embase.

Fibroblasts in omentum activated by tumor cells promote ovarian cancer growth, adhesion and invasiveness.

Omentum metastasis is a common occurrence in epithelial ovarian cancer (EOC), which is often accompanied by ascites that facilitates the spread of EOC cells. A subpopulation of fibroblasts-the cancer-associated fibroblasts (CAFs) are important promoters of tumor progression. We have shown previously that CAFs exist not only in omentum with EOC metastasis but also in omentum without metastasis.

[Molecular mechanisms of plant resistance to cadmium toxicity].

Cadmium (Cd) is a non-essential trace element for plants, and has strong toxicity at low concentrations. It can suppress the elongation growth of plant cell, inhibit oxidative mitochondrial phosphorylation, induce oxidative stress, inhibit the activities of several antioxidative enzymes, affect photosynthesis by inhibiting ferrous reductase or damaging photosynthesis apparatus, and cause the alteration of chromatin and the change of plasma membrane ATPase activity. In response to Cd stress, the cells of cadmium-resistant plant species can produce a number of proteins such as phytochelatins, metallothioneins and stress proteins to detoxify Cd ions, and efficiently repair Cd damage.

Analysis of genotypic and environmental effects on rice starch. 2. Thermal and retrogradation properties.

Eight rice varieties with wide diversity in apparent amylose content (AC) were selected and planted in the early (HZE) and late season (HZL) in Hangzhou and in the winter season in Hainan (HN) for two consecutive years to study the genotypic and environmental effects on starch thermal and retrogradation properties of grain. Genotypic variation (all at P < 0.01) accounted for >56% of the total variation for onset (T(o)), peak (T(p)), and completion (T(c)) temperature, width at half-peak height (DeltaT(1/2)) of gelatinization, enthalpy (DeltaH(r)) of retrograded starch, percentage of retrogradation (R%), and 45.
