The Efficacy of the Cook–Swartz Implantable Doppler in the Detection of Free-Flap Compromise: A Systematic Review and Meta-Analysis

open access: yesJournal of Reconstructive Microsurgery Open, 2016
Background Reducing free-flap failure rates is a key goal of any microsurgical unit. The Cook–Swartz implantable Doppler (CSD) can be used to monitor flap vascularity.

On the Importance of Halogen–Halogen Interactions in the Solid State of Fullerene Halides: A Combined Theoretical and Crystallographic Study

open access: yesCrystals, 2017
In this manuscript, we combined DFT (Density Functional Theory) calculations (BP86-D3/def2-TZVP level of theory) and a search in the CSD (Cambridge Structural Database) to analyze the role of halogen–halogen interactions in the crystal structure of ...

Caesarean Scar Ectopic Pregnancy in Early Gestation: A Scoping Review of Definitions and Diagnostic Approach. [PDF]

open access: yesBJOG
ABSTRACT Background Caesarean scar ectopic pregnancy (CSEP) is defined by the implantation and development of a gestational sac inside a caesarean scar defect, but variations in classification systems and diagnostic criteria exist. Objectives This study aimed to systematically review the different criteria used in the medical literature to diagnose ...

Optimal eddy viscosity for resolvent-based models of coherent structures in turbulent jets [PDF]

open access: yes, 2021
Response modes computed via linear resolvent analysis of a turbulent mean-flow field have been shown to qualitatively capture characteristics of the observed turbulent coherent structures in both wall-bounded and free shear flows.

Regium Bonds between Silver(I) Pyrazolates Dinuclear Complexes and Lewis Bases (N2, OH2, NCH, SH2, NH3, PH3, CO and CNH)

open access: yesCrystals, 2020
A theoretical study and Cambridge Structural Database (CSD) search of dinuclear Ag(I) pyrazolates interactions with Lewis bases were carried out and the effect of the substituents and ligands on the structure and on the aromaticity were analyzed.

Hidradenitis suppurativa and risk of coronary artery disease: A systematic review and meta-analysis

open access: yesIndian Journal of Dermatology, 2023
Background: Patients with hidradenitis suppurativa (HS) may have a higher risk of coronary artery disease (CAD) due to the excessive inflammatory burden. However, data on this association is still relatively limited.
