Determination of Intact Parabens in the Human Plasma of Cancer and Non-Cancer Patients Using a Validated Fabric Phase Sorptive Extraction Reversed-Phase Liquid Chromatography Method with UV Detection.

Parabens have been widely employed as preservatives since the 1920s for extending the shelf life of foodstuffs, medicines, and daily care products. Given the fact that there are some legitimate concerns related to their potential multiple endocrine-disrupting properties, the development of novel bioanalytical methods for their biomonitoring is crucial. In this study, a fabric phase sorptive extraction reversed-phase liquid chromatography method coupled with UV detection (FPSE-HPLC-UV) was developed and validated for the quantitation of seven parabens in human plasma samples.

Fabric phase sorptive extraction combined with high-performance-liquid chromatography-photodiode array analysis for the determination of seven parabens in human breast tissues: Application to cancerous and non-cancerous samples.

An improved pretreatment approach of human breast tissue is demonstrated for subsequent analysis of seven parabens including methyl paraben (MPB), ethyl paraben (EPB), propyl paraben (PPB), butyl paraben (BPB), isopropyl paraben (iPPB), isobutyl paraben (iBPB), and benzyl paraben (BzPB). Specifically, a well-designed homogenization procedure, conjugated with an optimized fabric phase sorptive extraction (FPSE) protocol, resulted in a carefully outlined sample preparation process as part of a green, simple, sensitive, economical and fast HPLC-PDA analytical method in agreement with Green Analytical Chemistry (GAC) demands. Among all tested FPSE membranes, the highest extraction efficiency was achieved by employing sol-gel poly(tetrahydrofuran) (sol-gel PTHF) coating on 100% cotton cellulose fabric that represents a medium polarity microextraction device, which combined the advanced material characteristics of sol-gel sorbent and the rich surface chemistry of an inherent porous cellulose fabric substrate.

An improved fabric-phase sorptive extraction protocol for the determination of seven parabens in human urine by HPLC-DAD.

An improved fabric-phase sorptive extraction (FPSE) protocol has been developed and validated herein for the simple, fast, sensitive and green determination of seven parabens-methyl paraben, ethyl paraben, propyl paraben, butyl paraben, isopropyl paraben, isobutyl paraben and benzyl paraben-in human urine samples by HPLC-DAD. The mobile phase consisted of ammonium acetate (0.05 m) and acetonitrile, while total analysis time was 13.

Synergistic effects of parabens and plastic nanoparticles on proliferation of human breast cancer cells.

Many personal care products on the market contain endocrine disrupting chemicals, including parabens. Parabens are well known chemical additives used as preservatives. They have been found in mammary glands and breast cancer tissues.

Feasibility study of determining a risk assessment model for obstructive sleep apnea in children based on local findings and clinical indicators.

Objective: To test a feasible and reliable model for diagnosing obstructive sleep apnea (OSA) in children, based on the clinically relevant parameters, in comparison to a polysomnography.

Methods: A total of 94 children with the suspected underlying OSA were included in the analyses. An association between clinical parameters (modified Mallampati score, tonsil size, adenoid size, age, gender, and body mass index) and apnea-hypopnea index (AHI) obtained following an overnight polysomnography was assessed, and significant variables were incorporated in the logistic regression model.

The "dermal cage": Inferiorly based dermal flap technique for breast reconstruction after mastectomy.

"Direct to implant," "one-stage," or "immediate" breast reconstruction procedures have become extremely popular in the last decade. The additional task of covering the lower pole of the prosthetic implant for stability can be achieved by one of two principal methods: either the use of acellular dermal matrix (ADM) or alternatively by the use of autologous dermis (inferiorly based dermal flap). In 2013, we published a modification of the inferior pedicle technique for reduction mammaplasty with the principal goal of making a strong, durable, and internalized ``dermal cage'' fixed to the chest wall to support the remaining breast tissue and to prevent the long-term descent of the breast tissue through the effects of gravity.

Formula for the prediction of apnea / hypopnea index in children with obstructive sleep apnea without polysomnography according to the clinical parameters: Is it reliable?

Purpose Of The Study: The aim of the study was to propose "the risk formula" for obstructive sleep apnea in children according to the general and local clinical parameters and findings relevant for obstructive sleep apnea (OSA) severity. The unmet need for this formula arises from the economic burden of polysomnography (device, staff, training, special sleep centers, etc) as the golden standard for the diagnostics.

Materials And Methods Used: The study was performed from January 2013 until January 2016 in the Sleep Center, Department for Neuroscience, School of Medicine of the University of Split, Department of Pediatrics, University Hospital Split, Croatia and ENT Dept.

Are postoperative behavioural changes after adenotonsillectomy in children influenced by the type of anaesthesia?: A randomised clinical study.

Background: Negative postoperative behavioural changes (NPOBCs) are very frequent in children after surgery and general anaesthesia. If they persist, emotional and cognitive development may be affected significantly.

Objective: To assess whether the choice of different anaesthetic techniques for adenotonsillectomy may impact upon the incidence of NPOBC in repeated measurements.

Skin and nipple-areola complex sparing mastectomy in breast cancer patients: 15-year experience.

Skin and nipple-areola complex sparing mastectomy (SNSM) and primary reconstruction have been popular for breast cancer treatment in the last decade. An advantage of the SNSM technique is the removal of all breast tissue as a radical surgical procedure while preserving native breast integrity, nipple-areola complex (NAC), and submammary fold. This retrospective 15-year clinical study analyzes medical records from our breast surgery database collected at our department between 1997 and 2012.

Clinical and patohistological factors affecting the 5 year survival rate in a population of Croatian women with invasive ductal breast carcinoma.

Breast carcinoma falls into a heterogeneous group of diseases which can be determined by various prognostic factors. The identification of clinical and histopathologic factors is of great value in predicting the progression of tumor growth and survival outcome. Due to a high degree of cell proliferation in breast tumors and high genetic instability of these tumors, as a consequence of defective DNA repair mechanisms, chemotherapy as a treatment option often renders very successful results.

Research needs in allergy: an EAACI position paper, in collaboration with EFA.

In less than half a century, allergy, originally perceived as a rare disease, has become a major public health threat, today affecting the lives of more than 60 million people in Europe, and probably close to one billion worldwide, thereby heavily impacting the budgets of public health systems. More disturbingly, its prevalence and impact are on the rise, a development that has been associated with environmental and lifestyle changes accompanying the continuous process of urbanization and globalization. Therefore, there is an urgent need to prioritize and concert research efforts in the field of allergy, in order to achieve sustainable results on prevention, diagnosis and treatment of this most prevalent chronic disease of the 21st century.

Current trends in breast reduction.

Results of our study describe the long term effects of reduction mammaplasty. Many women with excessively small or large breasts have an altered personal self-image and often suffer from low self-esteem and other psychological stresses. This procedure is designed to reduce and reshape large breasts, and since the size, shape, and symmetry of a woman's breasts can have a profound effect on her mental and physical well-being it is important to observe the patient's long-term outcome.

Necrotizing fasciitis: literature review of contemporary strategies for diagnosing and management with three case reports: torso, abdominal wall, upper and lower limbs.

Necrotizing fasciitis (NF) is an uncommon soft tissue infection, usually caused by toxin-producing virulent bacteria. It is characterized by widespread fascial necrosis primarily caused by Streptococcus hemolyticus. Shortly after the onset of the disease, patients become colonized with their own aerobic and anaerobic microflora from the gastrointestinal and/or urogenital tracts.

Is the systemic inflammatory reaction to surgery responsible for post-operative pain after tonsillectomy, and is it "technique-related"?
