Triple-negative breast cancer is one of the least responsive breast cancer subtypes to available targeted therapies due to the absence of hormonal receptors, aggressive phenotypes, and the high rate of relapse. Early breast cancer prevention may therefore play an important role in delaying the progression of triple-negative breast cancer. Cancer stem cells are a subset of cancer cells that are thought to be responsible for tumor progression, treatment resistance, and metastasis. We have previously shown that vitamin D compounds, including a Gemini vitamin D analog BXL0124, suppress progression of ductal carcinoma in situ in vivo and inhibit cancer stem-like cells in MCF10DCIS mammosphere cultures...

BACKGROUND: Multiple sclerosis (MS) is a chronic and debilitating disease of the central nervous system that affects more than 570,000 persons in the United States and 2.3 million worldwide. Since most individuals experience initial symptoms between the ages of 20 and 40 years, MS can have a significant effect on health care consumption, quality of life, productivity, and employment over the long-term disease course. Opportunities exist to better understand how benefit design and other nonclinical factors can affect health care delivery and associated costs...

BACKGROUND: Inequity in access and use of child and maternal health services is impeding progress towards reduction of maternal mortality in low-income countries. To address low usage of maternal and newborn health care services as well as financial protection of families, some countries have adopted demand-side financing. In 2010, Tanzania introduced free health insurance cards to pregnant women and their families to influence access, use, and provision of health services. However, little is known about whether the use of the maternal and child health cards improved equity in access and use of maternal and child health care services...

A reliable analytical method based on high-performance liquid chromatography-ultraviolet detection was established for the determination of oleanonic acid (OA) content in Chios gum mastic (CGM). A simple method involving methanol extraction of CGM powder followed by basification and ether extraction was developed to isolate the triterpenic fraction including OA. The triterpenic fraction was chromatographed on a Phenomenex Gemini C18 column (150 × 4.6 mm, 5 µm) under a simple gradient elution of a mobile phase containing acetonitrile and water at a flow rate of 1...

A zwitterionic gemini surfactant, called 2,2'-(1,4-phenylenebis(oxy))bis(N,N-dimethyl)-N-carboxyethyl-N-(alkylamide propyl) ammonium chloride (C14-B-C14), was synthesized successfully. The surfactant molecule exhibits various states at different pH values due to the two pH-sensitive carboxylate groups in the molecule. The surface activity and aggregate behaviors of C14-B-C14 in the aqueous solution were investigated under different pH conditions. The surface activities of the surfactant decrease with the increase in pH due to higher hydrophilic properties under basic conditions...

INTRODUCTION: Gastrointestinal stromal tumours (GISTs) are the most common mesenchymal neoplasms (85%) of the gastrointestinal (GI) tract; duodenal GISTs constitute 3-5% of all GISTs and represent 10-30% of all malignant tumours of the duodenum. Rarely, patients present severe bowel obstruction, perforation or severe bleeding. The radical resection with complete removal of the tumour remains the main therapeutic approach. We performed a local resection in patients with suspected GIST admitted for emergency treatment for GI bleeding...

INTRODUCTION: Colon cancer therapy is primarily surgical. Advanced age does not represent a contraindication to surgery. We analyse the results of surgery in ultra 75 patients undergoing surgery for colorectal cancer by examining the correlation between the comorbidity and any post-operative complications. MATERIALS AND METHODS: We surgically treated 66 patients for colorectal cancer, aged over 75. The examined subjects were compromised for various reasons. We have evaluated the different influences of risk factors in elective and urgency operation...

BACKGROUND: Diverticular disease of the colon also affects older people. Generally, older patients with diverticulitis may be regarded as too risky to undergo surgery. This retroprospective multicentric observational study aims to assess the safety and benefits of laparoscopic peritoneal lavage (LPL) in elderly patients with perforated sigmoid diverticulitis. PATIENTS AND METHOD: We hospitalized in urgency 100 patients, aged over 75, for sigmoid diverticulitis. Sixty-nine patients were treated with conservative medical therapy, while 31 were treated surgically, in which the surgery was performed in urgency in 18 cases, while in election in 13 cases...

INTRODUCTION: Even with the advances in surgical technique and perioperative care, morbidity and mortality after colorectal cancer surgery remain considerable, and patients (pt) who present as an emergency have an even higher mortality and morbidity rate. METHODS: A total of 35 pt with caecum or ascending colon cancer between January 2007 and June 2015, three departments in Italy and in Poland, were included in the study. The intention of surgery in all cases was curative resection with ileo-colic anastomosis...

OBJECTIVE: Lymphocyte recruitment to the inflamed gut is increased in UC. Inhibition of this cell trafficking by vedolizumab (VDZ) was successful in inducing and maintaining remission and in induction of endoscopic mucosal healing. There are no data on histological healing with VDZ. We studied histological changes following VDZ therapy and compared gene expression in patients with UC before and after therapy. DESIGN: Forty-one patients with UC from GEMINI I and LTS were studied before and at three time points (weeks 6/12/52) following VDZ therapy...

Biological and thermodynamic properties of a new homologous series of highly fluorinated bispyridinium cationic gemini surfactants, differing in the length of the spacer bridging the pyridinium polar heads in 1,1' position, are reported for the first time. Interestingly, gene delivery ability is closely associated with the spacer length due to a structural change of the molecule in solution. This conformation change is allowed when the spacer reaches the right length, and it is suggested by the trends of the apparent and partial molar enthalpies vs molality...

BACKGROUND: 'Food fussiness' (FF) is the tendency to be highly selective about which foods one is willing to eat, and emerges in early childhood; 'food neophobia' (FN) is a closely related characteristic but specifically refers to rejection of unfamiliar food. These behaviors are associated, but the extent to which their etiological architecture overlaps is unknown. The objective of this study was to quantify the relative contribution of genetic and environmental influences to variation in FF and FN in early childhood; and to establish the extent to which they share common genetic and environmental influences...

Gemini supra-amphiphiles with different spacer lengths, [M-n-M](2+)@2[DBS](-) (n = 2, 6, 10), were easily constructed. The conformational flexibility and hydrophobicity of the spacer group can be effectively tailored through regulating the spacer length, leading to the fine control of the topologies and subsequent hierarchical self-assemblies of [M-n-M](2+)@2[DBS](-). Vesicles are primarily fabricated by [M-n-M](2+)@2[DBS](-), and then successively fused into vesicle clusters, nanotubes, and planar bilayers, whose bilayer curvatures are gradually decreased, with increasing spacer length...

In this paper the interfacial behavior of aqueous solutions of cationic gemini surfactants of the, N,N'-bis(dimethylalkyl)-α,ω-alkanediammoniumdibromide type (known as the 12-s-12 series), in the absence and presence of ZnO nanoparticles was studied. Equilibrium and dynamic interfacial tension between n-decane and aqueous surfactant solutions were investigated. It was concluded that the synergistic effect between surfactants and nanoparticles increases the surfactant efficiency with respect to reducing the interfacial tension...
