A nanomaterial-based breath test for distinguishing gastric cancer from benign gastric conditions

2013

Background: Upper digestive endoscopy with biopsy and histopathological evaluation of the biopsy material is the standard method for diagnosing gastric cancer (GC). However, this procedure may not be widely available for screening in the developing world, whereas in developed countries endoscopy is frequently used without major clinical gain. There is a high demand for a simple and non-invasive test for selecting the individuals at increased risk that should undergo the endoscopic examination. Here, we studied the feasibility of a nanomaterial-based breath test for identifying GC among patients with gastric complaints. Methods: Alveolar exhaled breath samples from 130 patients with gastric …

Novel Functionality of Lithium-Impregnated Titania as Nanocatalyst

2019

The present work incorporates the synthesis of a multifunctional catalyst for the transesterification of waste cooking oil (WCO) to biodiesel and recovery of rare earth elements (REEs). For this purpose, TiO2 nanoparticles and TiO2 doped with lithium ions were prepared. The influence of lithium ions on the catalytic performance of TiO2 was attained by impregnation of the different molar ratios of lithium hydroxide to bare TiO2. Then each catalyst was screened for catalytic conversion of WCO to fatty acid methyl ester (FAME) and also for REEs recovery. All synthesized materials were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), Transmission electron microsc…

Identification of markers that can be recognised using spectroscopic sensors and which reflect key stages in the cooking of meat and fish

2016

One of the purposes of the Opticook project is to install spectroscopic sensors in ovens, so equipping them with non intrusive tools allowing following cooking process of meat and fish. The hypothesis on which sensors were developed was: are muscular proteins proper probes to discriminate among several cooking degrees? Thus, at the beginning of the project several tools were used to characterise effect of several cooking degrees on macroscopic properties (texture and colour) of beef, chicken and cod fillet samples. Following, calorimetry and spectroscopic techniques were used to study transformations at molecular scale. In particular, visible spectroscopy followed denaturation of haemprotei…

Predictive Role of the p16 Immunostaining Pattern in Atypical Cervical Biopsies with Less Common High Risk HPV Genotypes

2021

P16 immunostaining is considered a useful surrogate of transcriptionally active high-risk (hr) HPV infection. Only strong and widespread “block-like” immunoreactivity is considered specific, whereas weak/focal p16 positive immunostaining is considered not specific, and follow-up and HPV molecular detection is not indicated. The aim of the study was to evaluate the presence of HPV DNA and Ki67 immunostaining in 40 cervical atypical biopsies (CALs) with mild and focal histological features suggestive of HPV infection—20 cases with weak/focal p16 positive immunoreactivity and 20 cases negative for p16 expression. In 16/20 weak/focal p16 positive CALs (80%), the INNO-LiPA HPV genotyping detecte…

Expression of selected molecular factors in two types of endometrial cancer

2021

BACKGROUND Endometrial cancers (EC) are a heterogeneous group of malignant neoplasms differing in etiology, clinical-pathological features and prognosis. OBJECTIVES To determine the differences between the expression of selected molecular factors and find connections between them in order to isolate possible biomarkers influencing treatment options. MATERIAL AND METHODS The investigated data involved archival histological preparations obtained from uterine EC samples taken from 137 patients, treated surgically between 2007 and 2014. The immunohistochemical Dako EnVisionTM Flex+ method was applied. RESULTS The expression of ERβ, MLH1 and BRCA1 was lower in ECI than in ECII patients. The ERα …

Skewed Differentiation of Circulating Vγ9Vδ2 T Lymphocytes in Melanoma and Impact on Clinical Outcome

2016

OBJECTIVE:The aim of this study was to evaluate over time circulating γδ T lymphocytes in melanoma patients in terms of frequency, effector functions, and relationship with clinical stage and evolution, by comparing preoperative values to those obtained at a mean follow-up of 36 months or in the event of recurrence or disease progression, and to those of healthy controls. Also, we correlated the presence of tumor-infiltrating γδ T lymphocytes with clinical evolution of melanoma. RESULTS:Mean frequencies of circulating γδ T cells before and after melanoma removal were very similar and comparable to healthy subjects, but patients who progressed to stage III or IV showed a significantly decrea…

Optimum combination therapy regimens for HIV/HCV infection

2016

HIV-HCV co-infection mostly affects intravenous drug users, in whom prevalence has tended to decrease in recent years, while it has increased in men who have sex with men, with occurrence of acute hepatitis C. Hepatitis C has a poorer prognosis in patients co-infected with HIV, as clinical progression is faster and degree of hepatic fibrosis is greater. However, optimized ARV treatment is clearly associated with slower progression to hepatic complications. Interactions between HCV and HIV drugs are numerous, which underlines the importance of pharmacological advice for HIV-treated patients before they start HCV treatment. In HIV-HCV co-infection, treatment of hepatitis C has to be offered a…

Investigating the possible impact of peritoneal tumor exposure amongst women with early stage cervical cancer treated with minimally invasive approac…

2021

Abstract Introduction Recent findings show a detrimental impact of the minimally invasive approach on patients with early stage cervical cancer (ECC). Reasons beyond these results are unclear. The aim of the present article is to investigate the possible role of peritoneal contamination during intracorporeal colpotomy. Methods patients with early stage cervical cancer were divided into 2 groups: no intraperitoneal exposure (N-IPE) intraperitoneal exposure (IPE) during minimally invasive surgery. Patients of the 2 groups were propensity-matched according to the major risk factors. Results 226 cases of the IPE group had a significant worst prognosis than the 142 cases of the N-IPE group (4.5-…

Long-term results of conventional myotomy in patients with achalasia: a prospective 20-year analysis.

2006

Myotomy has proved to be an efficient primary therapy in patients with achalasia, especially in younger patients (<40 years of age). The results of laparoscopic myotomy cannot be finally assessed, on account of the shorter postoperative follow-up. Thus, there are considerable data regarding intermediate-term outcomes after laparoscopic myotomy. The aim of our study was a 20-year analysis of the conventional cardiomyotomy as the underlying basis assessing the results of minimal-invasive surgery. Within 20 years (September 1985 through September 2005), 161 operations for achalasia were performed in our clinic. Enrolled in this study were 108 patients with a conventional, transabdominal myotom…
