Bisphenol-A (BPA) has been considered as an endocrine disrupting chemical (EDC) because it can exert estrogenic properties. For bisphenol-S (BPS) and bisphenol-F (BPF) that are BPA analogs and substitutes, their risk to estrogen-dependent cancer has been reported rarely compared with the numerous cases of BPA. In this study, we examined whether BPA, BPS, and BPF can lead to the proliferation, migration, and epithelial mesenchymal transition (EMT) of MCF-7 clonal variant (MCF-7 CV) breast cancer cells expressing estrogen receptors (ERs)...

The objective of the work was to check the presence of Non-Intended Added Substances (NIAS) with hormonal activities in aluminium coatings extracts coded: AA, BBF, MC and RR, furnished by four different suppliers. Water samples were prepared at room temperature or at 40°C for three months to verify the storage effect on the coatings. Solid phase extraction was used to concentrate and to extract coating substances. Hormonal activities were checked in vitro using reporter gene bioassays. Except BBF, all extracts induced a weak but significant estrogenic agonist activity in the human cell line...

Immunotherapy is becoming a standard of care for many cancers. Immune-checkpoint inhibitors (ICI) can generate immune-related adverse events. Interstitial lung disease (ILD) has been identified as a rare but potentially severe event.Between December 2015 and April 2016, we conducted a retrospective study in centres experienced in ICI use. We report the main features of ICI-ILD with a focus on clinical presentation, radiological patterns and therapeutic strategies.We identified 64 (3.5%) out of 1826 cancer patients with ICI-ILD...

BACKGROUND: Immune thrombocytopenia (ITP) during childhood spontaneously remits in up to 80% of children. Predictors of remission are not well understood. PROCEDURE: We analyzed data from Intercontinental Cooperative ITP Study Group (ICIS) Registry II, a large prospective cohort of children with ITP, to investigate factors that might predict remission. RESULTS: In ICIS Registry II, 705 patients had data collected through 12 months following diagnosis, with 383 patients having data available at 24 months as well...

OBJECTIVE: Lower urinary tract (LUT) dysfunction is a monumental problem affecting quality of life following neurotrauma, such as spinal cord injury (SCI). Proper function of the bladder and its associated structures depends on coordinated activity of the neuronal circuitry in the spinal cord and brain. Disconnection between the spinal and brain centers controlling the LUT causes fundamental changes in the mechanisms involved in the micturition and storage reflexes. We investigated the effects of cathodal trans-spinal direct current stimulation (c-tsDCS) of the lumbosacral spine on bladder and external urinary sphincter (EUS) functions...

REVIEW
Rawad Elias, Joshua Morales, Carolyn Presley
Non-small cell lung cancer (NSCLC) is mostly a disease of older adults, with its incidence and mortality rates increasing exponentially after the age of 65 years. Immune checkpoint inhibitors (ICIs) have changed the scene of NSCLC treatment after a long and relatively stagnant period of standard treatment regimens. However, little is known about the specific impact of these agents in older adults for whom care is often complicated by a variety of syndromes. This underlines the importance of understanding the dynamics of new cancer treatments in an older patient population...

ED affects a significant proportion of males worldwide. With an ever-aging population the prevalence of ED is predicted to double in the next decade. Oral PDE-5 inhibitors are the first-line treatment for ED and have revolutionised its management. These agents are however ineffective in some men. Intracavernosal injection (ICI) of vasoactive agents is an effective second-line therapy for ED. Despite proven efficacy, needle phobia and anxiety with self-needling limit the use of intracavernosal (IC) therapies...

Appropriate 'in vivo' models are crucial for studying breast cancer biology and evaluating the efficacy of therapeutic agents. Thus we engineered a novel transgenic mouse line expressing the human Ki-Ras bearing an activating mutation (Ki-Ras((G12V))) selectively in the mammary epithelium after lactation. These mice develop invasive ductal adenocarcinomas with 100% incidence within 3-9 months after Ki-Ras((G12V)) induction. Immunophenotyping revealed that the mammary tumors express luminal markers, are positive for estrogen and progesterone receptors, negative for HER2 and have a low proliferation index...

Bisphenol A (BPA), an environmental endocrine-disrupting organic chemical, has been positively associated with the rate of implantation failure of in vitro fertilization. However, the underlying mechanisms remain unclear. To reveal the impact and the underlying mechanism of BPA on the crosstalk between trophoblast and decidual stromal cells (DSCs), we determined whether BPA was able to affect trophoblast invasion in vitro. We found that BPA significantly inhibited CXCL8 expression in DSCs, which hindered trophoblast invasion, and activated the phosphorylation of ERK in DSCs...

Postchemotherapy cognitive impairment (PCCI) is commonly exhibited by cancer patients treated with a variety of chemotherapeutic agents, including the endocrine disruptor tamoxifen (TAM). The etiology of PCCI is poorly understood. Our goal was to develop high-throughput assay methods to test the effects of chemicals on neuronal function applicable to PCCI. Rat hippocampal neurons (RHNs) were plated in 96- or 384-well dishes and exposed to test compounds (forskolin [FSK], 17β-estradiol [ES]), TAM or fulvestrant [FUL], aka ICI 182,780) for 6-14 days...

The effects of β adrenergic receptors (β-ARs) and p38 mitogen-activated protein kinases (MAPK) pathways on cardiosphere-derived cells (CDCs) are largely unknown. This study aimed to investigate the roles of β-ARs and p38MAPK pathways on the proliferation, apoptosis and differentiation capacity of CDCs. The CDCs were treated with β1-AR blocker (Met group), β2-AR antagonist (ICI group) and p38MAPK inhibitor (SB group), nonselective β-AR blocker (PRO group), and β-AR agonist (ISO group). The viability, apoptotic rate and differentiation status of CDCs were determined by MST-1 assay, flow cytometery, and Western blot, respectively...

BACKGROUND: Recent observations of specific metal damage patterns on retrieved total joint implants implied a cellular origin and was termed inflammatory cell-induced (ICI) corrosion. Although ICI corrosion continues to present a potential damage source for metallic biomaterials surfaces, an alternate source of some damage patterns may arise from electrosurgery instruments in total joint arthroplasty. METHODS: To characterize electrosurgically-induced damage patterns on metal implants, a model system of highly polished CoCrMo and Ti-6Al-4V disks and commercial electrosurgical generator was evaluated in various modes and power settings using monopolar and bipolar configurations...

The safety, including the endocrine disruptive capability, of glyphosate-based herbicides (GBHs) is a matter of intense debate. We evaluated the estrogenic potential of glyphosate, commercial GBHs and polyethoxylated tallowamine adjuvants present as co-formulants in GBHs. Glyphosate (≥10,000 μg/L or 59 μM) promoted proliferation of estrogen-dependent MCF-7 human breast cancer cells. Glyphosate also increased the expression of an estrogen response element-luciferase reporter gene (ERE-luc) in T47D-KBluc cells, which was blocked by the estrogen antagonist ICI 182,780...

Erectile dysfunction (ED) is a worldwide commonly reported condition; epidemiological data showed a prevalence ranging from 2.3 to 53.4% within different population subsets. In this context, the advent of phosphodiesterase type 5 inhibitors (PDE5is) in the second mid of 1990s has deeply changed the treatment scenario of this bothersome condition. Being user-friendly compounds with an excellent overall safety profile, PDE5is emerged as the first-line treatment for ED, thus overcoming topical alprostadil and intracavernous injections (ICIs)...

The advent and success of immune checkpoint inhibitors (ICIs) in cancer treatment has broadened the spectrum of tumours that might be considered "immunogenic" and susceptible to immunotherapeutic (IT) intervention. Not all cancer types are sensitive, and not all patients with any given type respond. Combination treatment of ICIs with an established cytotoxic modality such as radiation therapy (RT) is a logical step towards improvement. For one, RT alone has been shown to be genuinely immunomodulatory and secondly pre-clinical data generally support combined ICI-RT approaches...

Immune checkpoint inhibitors (ICI) are now a therapeutic option for advanced non-small cell lung cancer (NSCLC) patients. ICI, such as the PD-1 inhibitors nivolumab and pembrolizumab and the PD-L1 inhibitor atezolizumab, have already been marketed for the treatment of pretreated patients with advanced NSCLC. Other notable PD-L1 inhibitors under development include avelumab and durvalumab. Areas covered: This article reviews literature on durvalumab development, from the preclinical data to the results of phase III clinical trials, whether published or presented at international scientific conferences...

BACKGROUND: In emergency medicine for determining the intracranial injury (ICI) in children with head trauma, usually brain CT scan is performed. Since brain CT scan, especially in children, has some disadvantages, it is better to find a procedure which could help to choose only the children with real head trauma injury for brain CT scan. AIMS: The aim of this study is to find such procedure. This study was descriptive, analytic and non-interventional. METHODS: We reviewed the archived files of children with head trauma injuries referred to the emergency department of Imam Hossein Hospital within two years...
