BACKGROUND: The Verona population-based breast cancer (BC) screening program provides biennial mammography to women aged 50-69 years. Based on emerging evidence of enhanced detection, the program transitioned to digital breast tomosynthesis (DBT) screening. METHODS: This is a prospective pilot evaluation of DBT with synthesised 2D mammography screening implemented during April 2015-March 2017; the rate and characteristics of cancers detected at DBT screening were compared with those detected at the preceding digital mammography (DM) screening round (April 2013-March 2015) in the same screening program...

The n-octanol/water partition coefficient (KOW ) is a physical/chemical property that is extensively used for regulatory and environmental risk and exposure assessments. The KOW value can estimate various chemical properties such as water solubility, bioavailability, and toxicity using quantitative structure-activity relationships which demands an accurate knowledge of this property. The present investigation aims to compare outcomes of three commonly cited methods of KOW measurement in the literature for six hydrophobic chemicals with insecticidal functions as well as highly volatile petroleum constituents...

Organotin compounds (OTs) are used in a range of industrial products, such as antifouling paints, agricultural pesticides and stabilizers. Owing to potential endocrine-disrupting effects, human exposure to such compounds is a concern. Nevertheless, little is known about the adverse effect of OTs on adrenocortical function in organisms. In this study, the human adrenocortical carcinoma cell (H295R) model was used to investigate effects of OTs on steroidogenesis and potential causes for such endocrine disruption was examined...

Recent research points to a shift from categorical diagnoses to a dimensional understanding of psychopathology and mental health disorders. In parallel, there has been a rise in newer psychosocial treatment modalities, which are inherently transdiagnostic. Transdiagnostic approaches are those that identify core vulnerabilities and apply universal principles to therapeutic treatment. As treatment of substance use disorders (SUD) must invariably accommodate such vulnerabilities, clinicians are finding such interventions useful...

The current research tested whether four dimensions of mindfulness - acceptance without judgment, observing, describing and acting with awareness - predicted frequency of nonsuicidal self-injury (NSSI) and mediate the relationship with NSSI outcomes during 20-weeks of Dialectical Behaviour Therapy (DBT) skills training for borderline personality disorder (BPD). Eighty-four self-harming individuals with BPD were randomized to either DBT skills training or to a waitlist control group. A series of regressions revealed no relationship between dimensions of mindfulness and NSSI at baseline...

Dialectical behavior therapy (DBT) is an effective treatment for an increasing number of mental disorders. Its increased application to a range of disorders has been prompted by the recognition that DBT targets emotion dysregulation, which is a transdiagnostic feature underlying several forms of psychopathology. More recently, DBT has been used to target additional clinically relevant domains that are outside diagnostically bound categories, such as improving parenting quality as a means of preventing psychopathology in children of parents with psychopathology...

Imposex is a disorder caused by organotins, mainly tributyltin, which results in the appearance of male sexual characteristics in females of gastropod mollusks. The main objective of this work was to make a critical analysis of the relationship between imposex and butyltin body burdens in Nucella lapillus and Nassarius reticulatus. Specifically, this study evaluates possible additive effects among butyltins, proposes scales of effects based on robust statistical criteria as alternatives to existing ones and defines the body burdens of TBT in N...

Since the sulfur specific cleavage is vital for the organic sulfur removal from fossil fuel, we explored potential bacterial strains of MTCC (Microbial Type Culture Collection) to desulfurize the Dibenzothiophene (DBT) through C-S bond cleavage (4-S pathway). MTCC strains Rhodococcus rhodochrous (3552), Arthrobacter sulfureus (3332), Gordonia rubropertincta (289), and Rhodococcus erythropolis (3951) capable of growing in 0.5 mM DBT were examined for their desulfurization ability. The presence of dsz genes as well as the metabolites was screened by polymerase chain reaction (PCR) and HPLC, respectively...

A direct and practical approach for the construction of DBTs was developed via a Pd-catalyzed tandem reaction, in which commercially available o-bromo-iodobenzenes combined with benzene thiols or iodobenzenes combined with o-bromo-benzene thiols were applied. These two approaches will provide an alternative for the synthesis of DBT derivatives.

Benthic macrofauna is one of the most widely used biological groups to assess the ecological status of marine systems. Lately, attention has been paid to similar use of benthic foraminifera. In this study, distribution patterns of benthic foraminiferal and macrofaunal species were investigated simultaneously in 11 fjords in southeastern Norway in order to assess correlations and responses to environmental conditions. Selected fjords allowed to investigate contrasted environmental conditions from low total organic carbon (TOC) content (sediment TOC < 2...

BACKGROUND: Given that alcohol misuse elevates risk of suicide death among ideators, the paucity of treatment outcome research for individuals presenting with both suicide ideation and problem drinking is particularly troubling. Dialectical behavior therapy (DBT) skills training, which effectively targets behaviors associated with emotion dysregulation including addictive and suicidal behaviors, provides a fitting model amenable to computerization. As stigma and scarcity stand as potential barriers to treatment, online dissemination platforms provide means for efficient treatment delivery that can augment the utility of suitable interventions...

Dibenzothiophene (DBT) and their derivatives, accounting for the major part of the sulfur components in crude oil, make one of the most significant pollution sources. The DBT sulfone monooxygenase BdsA, one of the key enzymes in the "4S" desulfurization pathway, catalyzes the oxidation of DBT sulfone to 2'-hydroxybiphenyl 2-sulfonic acid (HBPSi). Here, we determined the crystal structure of BdsA from Bacillus subtilis WU-S2B, at the resolution of 2.2 Å, and the structure of the BdsA-FMN complex at 2...
