The “chimney forest” of the deep Montenegrin margin, south-eastern Adriatic Sea
2015
A spectacular field of columnar carbonates has been discovered on the Montenegrin margin in the southern Adriatic Sea at a depth of about 450 m. The site exposes many columnar carbonates protruding from the substrate or abated on the bottom. Such carbonates attain maximum visible lengths of ca. 60 cm with diameters up to 20 cm; display an annular growth, and are either hollow or plugged by indurated sediment. Petrographic and geochemical analyses document the pervasive presence of dolomite, and delta C-13 values as low as -30%(0) VPDB. These 'chimneys' are therefore interpreted as former conduits related to hydrocarbon expulsion in this sector of the Adriatic basin. However, available data …
Endometrial receptivity revisited: endometrial transcriptome adjusted for tissue cellular heterogeneity
2018
Study question Does cellular composition of the endometrial biopsy affect the gene expression profile of endometrial whole-tissue samples? Summary answer The differences in epithelial and stromal cell proportions in endometrial biopsies modify the whole-tissue gene expression profiles and affect the results of differential expression analyses. What is already known Each cell type has its unique gene expression profile. The proportions of epithelial and stromal cells vary in endometrial tissue during the menstrual cycle, along with individual and technical variation due to the method and tools used to obtain the tissue biopsy. Study design, size, duration Using cell-population specific trans…
Phase II Study of Taselisib (GDC-0032) in Combination with Fulvestrant in Patients with HER2-Negative, Hormone Receptor–Positive Advanced Breast Canc…
2018
AbstractPurpose: This single-arm, open-label phase II study evaluated the safety and efficacy of taselisib (GDC-0032) plus fulvestrant in postmenopausal women with locally advanced or metastatic HER2-negative, hormone receptor (HR)-positive breast cancer.Patients and Methods: Patients received 6-mg oral taselisib capsules daily plus intramuscular fulvestrant (500 mg) until disease progression or unacceptable toxicity. Tumor tissue (if available) was centrally evaluated for PIK3CA mutations. Adverse events (AE) were recorded using NCI-CTCAE v4.0. Tumor response was investigator-determined using RECIST v1.1.Results: Median treatment duration was 4.6 (range: 0.9–40.5) months. All patients expe…
Pooled analysis of prospective European studies assessing the impact of using the 21-gene Recurrence Score assay on clinical decision making in women…
2016
PURPOSE: The 21-gene Recurrence Score assay (Oncotype DX) provides prognostic/predictive information in oestrogen receptor positive (ER+) early breast cancer, but access/reimbursement has been limited in most European countries in the absence of prospective outcome data. Recently, two large prospective studies and a real-life 5-year outcome study have been reported. We performed a pooled analysis of prospective European impact studies to generate robust data on impact of use in different clinical subgroups. METHODS: The analysis included four studies (French, German, Spanish, and British) in ER+ human epidermal growth factor receptor 2-negative breast cancer patients (n = 527). Node-positiv…
Topical application of the Wnt/β-catenin activator methyl vanillate increases hair count and hair mass index in women with androgenetic alopecia
2016
Activation of the WNT/β-catenin pathway has emerged as a potential therapeutic target in androgenetic alopecia (AGA). Methyl vanillate (MV) - a safe plant-derived ingredient - has been recently shown to activate the WNT/β-catenin signaling. Objectives Two distinct substudies were conducted. First, we designed a 6-month, uncontrolled, open-label clinical study to investigate whether topically applied MV may increase hair count and hair mass index (HMI) in female AGA. Second, we conducted a molecular study on the effect of MV on WNT10B mRNA expression in scalp biopsies of women with AGA. A total of 20 Caucasian women (age range: 25-57 years) with AGA (Sinclair grade 1-2) were included. The re…
Self-esteem and binge eating: Do patients with binge eating disorder endorse more negatively worded items of the Rosenberg Self-Esteem Scale?
2020
Objective Self-esteem is a core aspect of eating disorder symptomatology. This study aims to examine whether method effects associated with negatively worded items of the Rosenberg Self-Esteem Scale (RSES) may interact the negative self-evaluations experienced by patients with obesity and binge eating disorder (BED). We also examined whether negatively worded items were associated with psychological distress and eating symptoms. Method Five hundred thirty three female outpatients (mean age: 42.59) with BED (n = 160) or obesity without BED (n = 373) completed the RSES and measures of interpersonal problems, psychological distress, and eating symptoms. Results Patients with BED responded more…
Risk assessment and monitoring programme of nitrates through vegetables in the Region of Valencia (Spain)
2017
This study was carried out to determine current levels of nitrate in vegetables marketed in the Region of Valencia (Spain) and to estimate the toxicological risk associated with their intake. A total of 533 samples of seven vegetable species were studied. Nitrate levels were derived from the Valencia Region monitoring programme carried out from 2009 to 2013 and food consumption levels were taken from the first Valencia Food Consumption Survey, conducted in 2010. The exposure was estimated using a probabilistic approach and two scenarios were assumed for left-censored data: the lower-bound scenario, in which unquantified results (below the limit of quantification) were set to zero and the up…
Allergen sensitizations in southern Italy: a 5-year retrospective study in allergic respiratory patients
2013
The assessment of the distribution of allergen skin test sensitizations is highly recommended for the optimal management of allergic respiratory conditions. We aimed at evaluating the distribution of allergen sensitizations in individuals with asthma and/or rhinitis in the Southern region of ltaly, and at exploring whether changes in the frequency of allergen sensitizations occurred after a 5-year period. Demographic data and skin prick test sensitizations to allergens from asthmatics and/or rhinitis attending the Division of Respiratory Diseases, University of Palermo, Italy in 2005 (Phase 1) and in 2010 (Phase 2) were extrapolated and retained for analysis. A total of 2033 allergic respir…
Clinical-anamnestic and instrumental data in outpatients suffering from venous disease
1995
The authors studied 200 consecutive outpatients with symptoms due to venous disease of the lower limbs. All the patients underwent anamnestic, clinical and instrumental evaluation (c.w. Doppler velocimetry and strain-gauge plethysmography). The results of this study showed that some anamnestic and clinical data are significantly related to venous disease detected by instrumental techniques. The superficial and deep vein hypertension were, instead, correlated to oral contraceptive use.
β-Adrenoceptor stimulation up-regulates phosphodiesterase 4 activity and reduces prostaglandin E 2 -inhibitory effects in human neutrophils
2000
Human neutrophils were treated for 4 h with a combination of salbutamol (1 µM), a β2-adrenoceptor agonist, and rolipram (30 µM), a selective phosphodiesterase 4 inhibitor, to investigate whether this treatment produces up-regulation of phosphodiesterase activity with functional consequences. Anion-exchange chromatography coupled with the use of selective activators and inhibitors demonstrated that a phosphodiesterase activity with characteristics of the isoenzyme type 4 was increased in drug-treated cells. Kinetic analysis showed a ~1.5-fold increase in V max without alteration of K m values. The augmented phosphodiesterase activity in drug-treated cells was abolished by actinomycin D. Cycl…
