Enhanced Catalytic Probe Design for Mapping Radical Density in the Plasma Afterglow.

The electrification of chemical processes using plasma generates an increasing demand for sensors, monitoring concentrations of plasma-activated species such as radicals. Radical probes are a low-cost in situ method for spatially resolved quantification of the radical density in a plasma afterglow using the heat from the exothermal recombination of radicals on a catalytic surface. However, distinguishing recombination heating from other heat fluxes in the system is challenging.

Methods: Intraocular pressure (IOP) was significantly elevated for 8 weeks in animals at different ages (10 days, 12 weeks, and 44 weeks) by episcleral vein cauterization. Retinal ganglion cells (RGCs) were quantified by anti-Brn3a immunohistochemical staining (IHC).

Delineating the Switch between Senescence and Apoptosis in Cervical Cancer Cells under Ciclopirox Treatment.

The iron-chelating drug ciclopirox (CPX) may possess therapeutic potential for cancer treatment, including cervical cancer. As is observed for other chemotherapeutic drugs, CPX can induce senescence or apoptosis in cervical cancer cells which could differently affect their therapy response. The present study aims to gain insights into the determinants which govern the switch between senescence and apoptosis in cervical cancer cells.

Effects of Metformin on the virus/host cell crosstalk in human papillomavirus-positive cancer cells.

Oncogenic types of human papillomaviruses (HPVs) are major human carcinogens. The viral E6/E7 oncogenes maintain the malignant growth of HPV-positive cancer cells. Targeted E6/E7 inhibition results in efficient induction of cellular senescence, which could be exploited for therapeutic purposes.

Adhesions after Laparoscopic Myomectomy: Incidence, Risk Factors, Complications, and Prevention.

Uterine fibroids or uterine myomas are one of the most common benign diseases of the uterus. Symptoms associated with myomas can make surgical removal of myomas necessary. Besides the traditional abdominal route, laparoscopic myomectomy (LM) has gained more acceptances over the last few decades, and it is anticipated that laparoscopy is associated with lower adhesion development.

Effects of the antifungal agent ciclopirox in HPV-positive cancer cells: Repression of viral E6/E7 oncogene expression and induction of senescence and apoptosis.

The malignant growth of human papillomavirus (HPV)-positive cancer cells is dependent on the continuous expression of the viral E6/E7 oncogenes. Here, we examined the effects of iron deprivation on the phenotype of HPV-positive cervical cancer cells. We found that iron chelators, such as the topical antifungal agent ciclopirox (CPX), strongly repress HPV E6/E7 oncogene expression, both at the transcript and protein level.

The HPV E6/E7 Oncogenes: Key Factors for Viral Carcinogenesis and Therapeutic Targets.

Human papillomavirus (HPV)-induced cancers are expected to remain a major health problem worldwide for decades. The growth of HPV-positive cancer cells depends on the sustained expression of the viral E6 and E7 oncogenes which act in concert with still poorly defined cellular alterations. E6/E7 constitute attractive therapeutic targets since E6/E7 inhibition rapidly induces senescence in HPV-positive cancer cells.

Laparoscopy or laparotomy as the way of entrance in myoma enucleation.

Purpose: Uterine myomas are the main cause of benign uterine diseases in premenopausal women. Objective of the present paper is to investigate the current best treatment modalities of myomas, depending on age of the patient and her desire to preserve fertility, as well as on clinical presentation of this pathology, such as size, number, and location of fibroids and, furthermore, on surgical experience of the gynecologist.

Methods: The design of our work is a systematic literature review of existing studies, reviews, and meta-analysis conducted in PubMed and Cochrane Library to identify relevant literature.

Uterine perforation following a fractional curettage successfully treated with the modified polysaccharide 4DryField® PH: a case report.

Background: Uterine perforation is the most common complication of curettage and may result in bleeding. Therefore, urgent control of bleeding from the uterine wall perforation is necessary to avoid an emergency hysterectomy or blood transfusion, to prevent peritoneal adhesion formation, possible chronic pelvic pain, and infertility. In the present case, an active bleeding secondary to a perforation of the uterus during curettage, for diagnosis of endometrial carcinoma, was instantaneously and successfully treated with only the application of a novel modified polysaccharide powder.

Gynaecological endoscopic surgical education and assessment. A diploma programme in gynaecological endoscopic surgery.

In recent years, training and education in endoscopic surgery has been critically reviewed. Clinicians, both surgeons as gynaecologist who perform endoscopic surgery without proper training of the specific psychomotor skills, are at higher risk to increased patient morbidity and mortality. Although the apprentice-tutor model has long been a successful approach for training of surgeons, recently, clinicians have recognised that endoscopic surgery requires an important training phase outside the operating theatre.

Long term follow-up concerning safety and efficacy of novel adhesion prophylactic agent for laparoscopic myomectomy in the prospective randomized ADBEE study.

We conducted a prospective randomized single blind - subject study in the University Clinic of Gynecology of Pius-Hospital Oldenburg. The primary objective of the ADBEE study was to assess the safety and manageability of ADBLOCK when used as an adjunct to laparoscopic surgery for the primary of myomas in women wishing to improve pregnancy outcomes. The study population included 32 women aged between 18-45 years, in good general health condition, who have not completed their family planning and who are undergoing primary ('virgin') laparoscopic myomectomy with an aim to improve pregnancy outcomes.

Plastic neo-vaginal construction in Mayer-Rokitansky-Küster-Hauser syndrome: an expert opinion paper on the decision-making treatment process.

Vaginal agenesis is a congenital anomaly that affects the life of one of each four thousand women around the world. There is a trend that patients request immediate surgical correction, instead of passive vaginal dilatation. Therefore a differentiated counselling should be provided.

How to avoid risks for patients in minimal-access trials: Avoiding complications in clinical first-in-human studies by example of the ADBEE study.

A clinical trial is a prospective study designed to establish the safety and efficacy of investigational devices in humans, in accordance with the strict guidelines of the Food and Drug Administration (FDA; USA) or European Medicines Agency (EMA; Europe). Before a clinical first-in-human study is initiated, preclinical studies of the investigational product are mandatory, and the results should be sufficient to indicate that the investigational device is acceptably safe for the proposed evaluation in human subjects. The present paper describes an experience of clinical trials, highlighting ways of avoiding possible complications in clinical first-in-human studies.

Adhesions are the major cause of complications in operative gynecology.

Adhesion formation has been found to be highly prevalent in patients with a history of operations or inflammatory peritoneal processes. These patients are at a high risk of serious intraoperative complications during a subsequent operation if adhesiolysis is performed. These complications include bowel perforation, ureteral or bladder injury, and vascular injury.

Insufflation with humidified and heated carbon dioxide in short-term laparoscopy: a double-blinded randomized controlled trial.

Background: We tested the hypothesis that warm-humidified carbon dioxide (CO2) insufflation would reduce postoperative pain and morphine requirement compared to cold-dry CO2 insufflation.

Methods: A double-blinded, randomized, controlled trial was conducted to compare warm, humidified CO2 and cold-dry CO2. Patients with benign uterine diseases were randomized to either treatment (n = 48) or control (n = 49) group during laparoscopically assisted vaginal hysterectomy.

Dysfunctional action control as a specific feature of Parkinson's disease.

Parkinson's disease (PD) is characterised by motor deficits as well as cognitive alterations, particularly concerning frontal lobe control. Here, we were interested in whether executive function is abnormal already early in PD, as well as whether this dysfunction worsens as a part of the dementia in PD. The following groups engaged in tasks addressing action control: PD patients with mild and advanced motor symptoms (aPD) without dementia, PD patients with dementia (PDD), patients with Alzheimer's disease (AD) and healthy subjects (CON).

The C2-domain protein QUIRKY and the receptor-like kinase STRUBBELIG localize to plasmodesmata and mediate tissue morphogenesis in Arabidopsis thaliana.

Tissue morphogenesis in plants requires communication between cells, a process involving the trafficking of molecules through plasmodesmata (PD). PD conductivity is regulated by endogenous and exogenous signals. However, the underlying signaling mechanisms remain enigmatic.
