Advances in Sustainable Catalysis: A Computational Perspective.

Front Chem 2019 12;7:182. Epub 2019 Apr 12.

School of Chemistry, Cardiff University, Cardiff, United Kingdom.

The enormous challenge of moving our societies to a more sustainable future offers several exciting opportunities for computational chemists. The first principles approach to "catalysis by design" will enable new and much greener chemical routes to produce vital fuels and fine chemicals. This prospective outlines a wide variety of case studies to underscore how the use of theoretical techniques, from QM/MM to unrestricted DFT and periodic boundary conditions, can be applied to biocatalysis and to both homogeneous and heterogenous catalysts of all sizes and morphologies to provide invaluable insights into the reaction mechanisms they catalyze.

Changing concepts in microsurgical pediatric varicocelectomy: is retroperitoneal approach better than subinguinal one?

Urol J 2015 Feb 22;12(1):2032-5. Epub 2015 Feb 22.

Department of Surgery and Transplantation, Center Bambino Gesù Children's Research Hospital, Via Torre di Palidoro 00050, Palidoro, Rome,

Purpose: To compare and to assess two different microsurgical "lymphatic-sparing" techniques (subinguinal/inguinal vs. retroperitoneal) used for the treatment of a pediatric and adolescent varicocele in terms of success rate, complications and mean operative time.

Materials And Methods: A retrospective study included 54 consecutive patients affected by a varicocele and treated with a microsurgical (loupes--operating microscope) magnification. Read More

Is 'object-centred neglect' a homogeneous entity?

Brain Cogn 2013 Feb 17;81(1):18-23. Epub 2012 Nov 17.

Center for Neuropsychological Research, Department of Neurosciences, Università Cattolica of Rome, Italy.

The nature of object-centred (allocentric) neglect and the possibility of dissociating it from egocentric (subject-centred) forms of neglect are controversial. Originally, allocentric neglect was described by Gainotti, D'Erme, Monteleone & Silveri (1986) and Gainotti, Messerli, & Tissot (1972) in patients who reproduced all the elements of a multi-object scene, but left unfinished the left side of one or more of them. More recently, however, Karnath, Mandler, and Clavagnier (2011) have claimed that the severity of allocentric neglect worsens when a complex 'object' shifts from an ipsilesional to a contralesional egocentric position.

Behavior in degenerative dementias: mood disorders, psychotic symptoms and predictive value of neuropsychological deficits.

Arch Gerontol Geriatr Suppl 2004 (9):365-78

Department of Geriatrics, Gerontology and Physiatrics-Memory Clinic, I-00168 Rome, Italy.

We studied mood disorders (MD) and psychotic symptoms (PS) in patients with fronto -temporal dementia (FTD) and Alzheimer's disease (AD) by means of different diagnostic instruments. These were: a subjective scale (subsets of survey psychiatric assessment schedule: SPAS), an objective scale (subsets of neuropsychiatric inventory: NPI) and a projective task (Wartegg completion task: WCT). A general tendency of NPI to over estimate the presence of symptoms compared to SPAS was observed, but distribution and severity of symptoms were quite homogeneous in the two dementia-groups, independently of the diagnostic scales.
