Influence of hypertension and other risk factors on the onset of sublingual varices.

BMC Oral Health 2021 May 4;21(1):235. Epub 2021 May 4.

Department of Engineering and Architecture, University of Trieste, Trieste, Italy.

Background: Sublingual varices (SV) are dilatations of tortuous veins that increased with age. Previous studies showed that this pathology could be correlated to some risk factors such as hypertension, age, gender and diabetes mellitus. In this study we evaluated, on a large number of subjects, the relationship between SV and different grades of hypertension as well as some risk factors extending the analysis to new risk factors such as dyslipidemia, obesity and antihypertensive therapy, modelling a possible dependence of SV on all these factors.

Alterations in connectivity of the bed nucleus of the stria terminalis during early abstinence in individuals with alcohol use disorder.

Alcohol Clin Exp Res 2021 Apr 8. Epub 2021 Apr 8.

Department of Psychiatry and Behavioral Sciences, Vanderbilt University Medical Center, Nashville, TN, USA.

Background: For individuals with Alcohol Use Disorder (AUD), long-term recovery is difficult in part due to symptoms of anxiety that occur during early abstinence and can trigger relapse. Research in rodent models of AUD has identified the bed nucleus of the stria terminalis (BNST), a small, sexually dimorphic, subcortical region, as critical for regulating anxiety-like behaviors during abstinence, particularly in female mice. Furthermore, prolonged alcohol use and subsequent abstinence alter BNST afferent and efferent connections to other brain regions. Read More

A Simplified Management of Transverse Testicular Ectopia in Patients with Persistent Mullerian Duct Syndrome.

Urol J 2020 05 27;0(0):237-239. Epub 2020 May 27.

Department of Pediatric Endocrinology, Ospedale Pediatrico Bambino Gesù, Rome, Italy.

Persistent müllerian duct syndrome (PMDS) in the majority of cases is discovered during surgery for inguinal hernia or cryptorchidism. A transverse testicular ectopia (TTE) with cryptorchidism may be very rarely associated to PMDS. Assuming that müllerian remnants have a very low malignant degeneration potential if compared to the malignancy risk of an undescended and not relocated testis, we describe a simplified surgical technique of orchiopexy that avoids an extensive anatomical dissection, in this way minimizing the risk of losing the deferential blood supply to the testis.

Mikrochim Acta 2020 04 28;187(5):296. Epub 2020 Apr 28.

Faculty of Bioscience and Technology for Food Agriculture and Environment, University of Teramo, 64100, Teramo, Italy.

A high-performance screen-printed electrode (SPE) based nanocomposite sensor integrating tungsten disulfide (WS) flakes decorated with catechin-capped gold nanoparticles (AuNP-CT) and carbon black (CB) has been developed. The excellent antifouling properties of WS decorated with AuNP-CT into a high conductivity network of CB results in high selectivity, sensitivity, and reproducibility for the simultaneous determination of hydroxycinnamic acid (hCN) structural analogs: caffeic (CF), sinapic (SP), and p-coumaric acids (CM). Using differential pulse voltammetry (DPV), the target hCNs resulted in three well-resolved oxidation peaks at SPE-CB-WS/AuNP-CT sensor. Read More

Altered corticolimbic connectivity reveals sex-specific adolescent outcomes in a rat model of early life adversity.

Elife 2020 01 20;9. Epub 2020 Jan 20.

Developmental Neuropsychobiology Laboratory, Department of Psychology, Northeastern University, Boston, United States.

Exposure to early-life adversity (ELA) increases the risk for psychopathologies associated with amygdala-prefrontal cortex (PFC) circuits. While sex differences in vulnerability have been identified with a clear need for individualized intervention strategies, the neurobiological substrates of ELA-attributable differences remain unknown due to a paucity of translational investigations taking both development and sex into account. Male and female rats exposed to maternal separation ELA were analyzed with anterograde tracing from basolateral amygdala (BLA) to PFC to identify sex-specific innervation trajectories through juvenility (PD28) and adolescence (PD38;PD48).
