Identification of cancer driver mutations in liquid-based cytology samples for the screening of endometrial diseases.

Background: Endometrial cancer (EC) is one of the leading causes of cancer death among women and early detection is crucial for its successful treatment. We previously showed that cytological examination combined with genetic analysis using liquid-based cytology (LBC) samples improved the diagnostic sensitivity of EC.

Methods: Among 218 individuals who underwent endometrial screening by LBC, 208 samples were analysed by cancer-panel sequencing.

Analysis of Treatment Response With Proteins Related to Tumor Immunity in Postoperative Irradiated Cervical Cancer Patients.

Background/aim: This study evaluated the association between programmed cell death-ligand 1 (PD-L1) and prognosis in patients with cervical cancer treated with postoperative radiation and the impact of neoadjuvant chemotherapy (NAC) on this association.

Patients And Methods: Immunohistochemical analysis was performed on biopsy specimens from 42 patients who did not receive NAC and from paired samples before (biopsies) and after (resected tissues) chemotherapy from 46 patients who received NAC to determine the association of PD-L1 with radiotherapy outcomes.

Results: In the non-NAC group, patients with ≥10% PD-L1-expressing tumor cells prior to treatment had better recurrence-free survival (RFS) than those with <10% PD-L1-expressing tumor cells (p=0.

Prediction of Mismatch Repair Status in Endometrial Cancer from Histological Slide Images Using Various Deep Learning-Based Algorithms.

The application of deep learning algorithms to predict the molecular profiles of various cancers from digital images of hematoxylin and eosin (H&E)-stained slides has been reported in recent years, mainly for gastric and colon cancers. In this study, we investigated the potential use of H&E-stained endometrial cancer slide images to predict the associated mismatch repair (MMR) status. H&E-stained slide images were collected from 127 cases of the primary lesion of endometrial cancer.

Mailing human papillomavirus self-sampling kits to women under-screened for cervical cancer improved detection in cervical cancer screening in a general population study in Japan.

Background: One cause of the increase in cervical cancer rates in Japan is the long-term stagnation in the cervical cancer screening consultation rate. Therefore, improving the screening consultation rate is of urgent concern to reduce cervical cancer incidence. Self-collected human papilloma virus (HPV) tests have been successfully adopted in several countries, such as the Netherlands and Australia, as a measure of individuals who have not undergone cervical cancer screening in national programs.

Predictive value of an exosomal microRNA-based signature for tumor immunity in cervical cancer patients treated with chemoradiotherapy.

Resistance of cervical cancer to radiotherapy with concurrent chemotherapy (CCRT) results in a poor prognosis. To identify new biomarkers for predicting the treatment response and prognosis, we explored exosomal microRNA (miRNA) expression signatures associated with the outcome of cervical cancer patients treated with CCRT. Exosomes were isolated from the plasma of 45 patients prior to CCRT during 2014-2020, and miRNA analysis was performed by next-generation sequencing.

Pathological classification of desmoplastic reaction is prognostic factor in cervical adenocarcinoma.

Desmoplastic reaction (DR) and inflammation are significant pathological manifestations of tumorigenesis in several cancers. However, the correlation between these stromal reactions and cervical adenocarcinoma has been poorly documented. This investigation elucidated whether DR is a prognostic indicator in early cervical adenocarcinoma patients.

Radical Vaginal Trachelectomy.

Recently, radical vaginal hysterectomy (RVH) has developed into laparoscopically assisted radical vaginal hysterectomy (LARVH), which is associated with the laparoscopical procedure, and it is applied as radical vaginal trachelectomy and semi-radical vaginal hysterectomy. LARVH is indicated for patients with stage IB1 and IIA1 cervical carcinoma, especially those with a tumor size of less than 2 cm, because the cardinal ligaments cannot be resected widely. Although RVH that is associated with laparoscopic pelvic lymphadenectomy is the most used surgical procedure, radical trachelectomy may be performed either abdominally or vaginally (laparoscopic or robotic).

Radiotherapy for HPV-related cancers: prediction of therapeutic effects based on the mechanism of tumor immunity and the application of immunoradiotherapy.

Human papillomavirus (HPV)-related cancer is one of the diseases entities for which the applications of radiotherapy have been increasing. Recently, the process of carcinogenesis from HPV infection and the mechanism of tumor immunity that develops during disease progression have been elucidated. In this review, we will describe the mechanism of tumor immunity and how chemoradiotherapy may overcome and improve the efficacy of tumor immunity.

Prediction of treatment response from the microenvironment of tumor immunity in cervical cancer patients treated with chemoradiotherapy.

To supplement clinical decision-making in the management of cervical cancer, various prognostic factors, including tumor immune microenvironments, were examined in patients with cervical cancer treated with definitive chemoradiotherapy. We retrospectively analyzed the expression of CD8, FoxP3, HLA-1, PD-L1, and XRCC4 in 100 cases of cervical cancer. The observed tumor immune microenvironments were also classified into three types: inflamed, excluded, and cold type.

Anaerobic co-digestion of dairy manure and Japanese knotweed (Fallopia japonica) under thermophilic condition: Optimal ratio for biochemical methane production.

Anaerobic co-digestion of animal manure and lignocellulosic biomass is a potent approach for sustainable biomethane production. Co-digestion of dairy manure (DM) and Japanese knotweed (JK), which was collected from a riverbank, was investigated at five different DM-to-JK mixing ratios (100:0, 90:10, 80:20, 60:40, and 0:100; wet weight basis) under thermophilic condition. The results showed that the methane yields obtain from the co-digestion of DM and JK were much higher than that obtained from JK alone (104 ml/gVS), which indicates the synergistic effect and the benefits of co-digesting JK with DM.

Are all wines made from various grape varieties beneficial in the prevention of myocardial infarction and stroke?

Aim: Epidemiologic studies support the assumption (French paradox hypothesis) that drinking red wine is beneficial in the prevention of cardiovascular diseases. Our recent works however cast doubt on such claim. Earlier we have shown that the antithrombotic activity of various fruits and vegetables mainly depends on their varieties.

ERα increases endometrial cancer cell resistance to cisplatin via upregulation of BAG3.

Endometrial cancer is a leading cause of cancer-associated mortality in women and has a poor prognosis in advanced stages. Our previous study revealed that BCL-2-associated athanogene 3 (BAG3) may contribute to enhancing cell viability through downregulation of microRNA (miR)-29b in endometrial cancer cell lines. In addition, a relationship between estrogen receptor α (ERα) and BAG3 was recently reported in several cancer cell types.

Association between cancer immunity and treatment results in uterine cervical cancer patients treated with radiotherapy.

Objective: To evaluate proteins related to tumor immune response and treatment outcome from radiotherapy for uterine cervical cancer patients.

Methods: We performed a retrospective immunohistochemical staining of 81 patients with uterine cervical cancer who underwent definitive radiotherapy. We examined the expression of programmed death ligand 1, human leukocyte antigen class I, tumor-infiltrating CD8+, and forkhead box P3+ (FoxP3+) T cells in tumor tissues.

Effect of solid-liquid separation on anaerobic digestion of dairy manure in semi-continuous stirred tank reactors: Process performance and digestate characteristics.

The objective of this study was to investigate the effect of solid-liquid separation on anaerobic digestion of dairy manure in semi-continuous stirred tank reactors. Reactors fed with liquid fraction of dairy manure (screened liquid manure) were kept in water baths at mesophilic (Run 1) and thermophilic (Run 3) temperatures, respectively, while reactors fed with water diluted manure and kept at mesophilic (Run 2) and thermophilic (Run 4) temperatures as control reactors. The performances of reactors were compared in terms of biogas and methane production, and digestate characteristics.

Anaerobic digestion for biogas production is one of the most used technology for bioenergy. However, the adoption of nanoparticles still needs further studies. Therefore, this study was designed to examine the effect of metal oxide nanoparticles (MONPs) at four different concentrations in two different combinations, 20 (R1) and 100 (R2) mg/L for FeO, 100 (R3) and 500 (R4) mg/L for TiO, and a mixture of FeO and TiO at rates of 20, 500 (R5) and 100, and 500 (R6), on hydrogen sulfide (HS) mitigation, biogas, and methane (CH) yield during the anaerobic digestion of cattle manure (CM) using an anaerobic batch system.

The survival of pathogenic bacteria and plant growth promoting bacteria during mesophilic anaerobic digestion in full-scale biogas plants.

The introduction of biogas plants is a promising way to recycle organic wastes with renewable energy production and reducing greenhouse gas. Application of anaerobic digestate as a fertilizer reduces the consumption of chemical fertilizers. In this study, the survival of pathogenic bacteria and plant growth promoting bacteria (PGPB) in two full-scale biogas plants operated at mesophilic condition were investigated.

Potential of anaerobic digestate of dairy manure in suppressing soil-borne plant disease.

Frequent use of pesticides to control soil-borne plant disease leads to environmental pollution and the development of pesticide resistance in phytopathogens. Soil amendment is considered to have the potential of suppressing plant disease because of its biological properties. However, information on anaerobic digestate is limited.
