Photochemical and Patternable Synthesis of 2D Covalent Organic Framework Thin Film Using Dynamic Liquid/Solid Interface.

2D covalent organic frameworks (COFs) are highly porous crystalline materials with promising applications in organic electronics. Current methods involve either on-surface synthesis (solid surface) or interfacial synthesis (liquid/liquid, liquid/gas interface) to create thin films for these applications, each with its drawbacks. On-surface synthesis can lead to contamination from COF powder or unreacted chemicals, while interfacial synthesis risks damaging the film during post-transfer processes.

Disparities between Uptake of Germline / Gene Tests and Implementation of Post-test Management Strategies in Epithelial Ovarian, Fallopian Tube, or Primary Peritoneal Cancer Patients.

Background: To assess the rate of germline gene tests in epithelial ovarian cancer (EOC) patients and uptake of post-test risk management strategies in /-mutated patients.

Methods: Institutional databases were searched to identify patients who were diagnosed with epithelial ovarian, fallopian tube, or primary peritoneal cancer (EOC) between 2009 and 2019 in two academic hospitals. Retrospective review on medical records was performed to collect clinico-pathologic variables, including performance of germline gene test and its results, as well as conduct of breast cancer screening tests and cascade testing.

Modulated electro-hyperthermia with weekly paclitaxel or cisplatin in patients with recurrent or persistent epithelial ovarian, fallopian tube or primary peritoneal carcinoma: The KGOG 3030 trial.

The present study (KGOG 3030) aimed to evaluate the safety of modulated electro-hyperthermia (mEHT) therapy with weekly administration of paclitaxel or cisplatin in female patients with recurrent or persistent epithelial ovarian, fallopian tube or primary peritoneal carcinoma. A total of 12 patients were randomized into the paclitaxel or cisplatin arm at a 1:1 ratio. Patients received weekly administration of paclitaxel (70 mg/m) or cisplatin (40 mg/m) intravenously on days 1, 8 and 15, and underwent mEHT therapy for 1 h on days 1, 4, 8, 11, 15, 18, 21 and 24 for each 4-week cycle.

Minimally invasive surgery for radical hysterectomy in women with cervical cancer: Korean Society of Gynecologic Oncology, Korean Society of Obstetrics and Gynecology, and Korean Society of Gynecologic Endoscopy and Minimally Invasive Surgery position statement.

On the basis of emerging data and the current understanding of minimally invasive surgery (MIS) for radical hysterectomy (RH) in women with cervical cancer, the Korean Society of Gynecologic Oncology, Korean Society of Obstetrics and Gynecology, and Korean Society of Gynecologic Endoscopy and Minimally Invasive Surgery support the following recommendations: According to the recently published phase III Laparoscopic Approach to Cervical Cancer (LACC) trial-a prospective randomized clinical trial-disease-free survival and overall survival rates of MIS RH are significantly lower than those of open RH. Gynecologic oncologists should be aware of the emerging data on MIS RH for early-stage cervical cancer. The results of the LACC trial, together with institutional data, should be discussed with patients before choosing MIS RH.

Serum anti-GAPDH autoantibody levels reflect the severity of cervical lesions: A potential serum biomarker for cervical cancer screening.

Recent studies have indicated that a certain level of autoantibodies may be essential for maintaining good health as well as preventing cancer development, and that the levels of serum autoantibodies can decline during malignant progression. The aim of the present study was to identify such an autoantibody-based biomarker for screening cervical lesions. An autoantigen reactive with healthy female sera was detected in the cytosolic fraction of HeLa cells, a cervical cancer cell line, and identified.

Clinical guidelines and position statement of Asian countries were presented by experts.

SPSB1 enhances ovarian cancer cell survival by destabilizing p21.

SPRY domain-containing SOCS box protein 1 (SPSB1) is an E3 ligase adaptor protein with unknown functions in cancer cells. In this study, we found that SPSB1 knockdown markedly decreased the viability and migration of ovarian cancer cells, while ectopic SPSB1 overexpression in IL-3-dependent Ba/F3 cells significantly increased their proliferation rate compared with empty vector-transfected cells. SPSB1 knockdown significantly elevated p21 protein and mRNA levels and induced apoptosis in ovarian cancer cells, as evidenced by increased levels of cleaved PARP and decreased levels of Bcl-2.

Profiling of serum antibodies against human papillomavirus antigens in Korean women with cervical intraepithelial neoplasia and cervical cancer.

Sero-epidemiological studies of human papillomavirus (HPV) have been undertaken over the last two decades. In this study, the prevalences of nine serum antibodies (anti-E6, E7 and L1 antibodies of HPV types 16, 18, and 58) were evaluated in normal (control) Korean women and women with cervical intraepithelial neoplasia (CIN) I, CIN II, CIN III, and cervical cancer. The frequencies of all types of anti-HPV antibodies were higher in the CIN stages and cervical cancer than in normal women, and those of anti-HPV16 E6 and E7, anti-HPV18 E6 and E7, and anti-HPV58 E7 antibodies were higher in the cervical cancer group than in the CIN stages.

Use of protein-based biomarkers of exfoliated cervical cells for primary screening of cervical cancer.

There has been no attempt to apply protein-based markers of exfoliated cervical cells (ECCs) for primary screening of cervical cancer. In the present study, the levels of six tumor-associated protein [TAPs: Sialyl Lewis A (SLeA), Cancer Antigen 15-3 (CA 15-3), p53, heat shock protein (Hsp)70, Hsp27 and squamous cervical carcinoma antigen (SCCA)]and of two human papillomavirus (HPV) viral proteins (HPV16 E7 and HPV16 L1) of ECCs lysates were evaluated by enzyme-linked immunosorbent assays (ELISAs).The wells of 96-well plates were coated with the ECCs lysates from normal, cervical intraepithelial neoplasia (CIN) I, CIN II, CIN III and cancer groups, and candidate proteins were detected by relevant antibodies.

Src is the primary target of aripiprazole, an atypical antipsychotic drug, in its anti-tumor action.

Aripiprazole (ARP) is an atypical anti-psychotic drug widely used to treat schizophrenia and bipolar disorder. The pharmacological effects of ARP on cancer cells are still poorly understood. In this study, anti-cancer effects of ARP on various malignant tumor cells and its molecular mechanism were further carefully examined by using cell proliferation assay, xenograft mouse model, immunoblotting analysis, migration assay, luciferase reporter gene assay, kinase assay, and overexpression strategy.

14-3-3ζ Overexpression is Associated with Poor Prognosis in Ovarian Cancer.

Purpose: 14-3-3ζregulates cell signaling, cell cycle progression, and apoptosis, and its overexpression is associated with disease recurrence and poor clinical outcomes in some solid tumors. However, its clinicopathological role in ovarian cancer is unknown. Our goal was to investigate whether 14-3-3ζis associated with ovarian cancer prognosis.

Aberrant single-minded homolog 1 methylation as a potential biomarker for cervical cancer.

Background: The aim of this study is to evaluate the possibility of using the methylation status of single-minded homolog 1 (SIM1) as a diagnostic biomarker for cervical cancer.

Methods: All the patient and normal specimens including the normal cervix (n = 10), cervical cancer tissues (n = 45), blood (n = 45), and cervical brush specimens (n = 110) were retrospectively obtained. Quantitative methylation-specific PCR was performed to detect SIM1 methylation in primary tumors, cervical brush specimens, and plasma circulating cell-free DNA (ccfDNA).

Profiling of Serum Metabolites Using MALDI-TOF and Triple-TOF Mass Spectrometry to Develop a Screen for Ovarian Cancer.

Purpose: We sought to develop a matrix assisted laser desorption ionization-time of flight (MALDI-TOF)-based, ovarian cancer (OVC), low-mass-ion discriminant equation (LOME) and to evaluate a possible supportive role for triple-TOF mass analysis in identifying metabolic biomarkers.

Materials And Methods: A total of 114 serum samples from patients with OVC and benign ovarian tumors were subjected to MALDI-TOF analysis and a total of 137 serum samples from healthy female individuals and patients with OVC, colorectal cancer, hepatobiliary cancer, and pancreatic cancer were subjected to triple-TOF analysis. An OVC LOME was constructed by reference to the peak intensity ratios of discriminatory low-mass ion (LMI) pairs.

Dopamine dependent setting of a circadian oscillator underlying the memory for time of day.

Animals learn and remember the time of day that significant conditions occur, and anticipate recurrence at 24-h intervals, even after only one exposure to the condition. On several place-conditioning tasks, animals show context avoidance or preference only near the time of day of the experience. The memory for time of day is registered by a circadian oscillator that is set at the time of the training.
