Robotic versus manual diagnostic and stenting procedures: a systematic review and meta-analysis.

Objective: Endovascular procedures are associated with improved outcomes and patient satisfaction compared to open surgery in selected cases. However, this is at the cost of increased radiation exposure. Robotic procedures are thought to minimize radiation exposure and may confer procedural efficacy due to the lack of operator fatigue.

Pinning Down Small Populations of Photoinduced Intermediates Using Transient Absorption Spectroscopy and Time-Dependent Density Functional Theory Difference Spectra to Provide Mechanistic Insight into Controlling Pyridine Azo Dynamics with Protons.

In this work, the impact of protonation on the photoisomerization ( → ) and reversion ( → ) of three pyridine-based azo dyes () is investigated by using a combination of transient absorption spectroscopy and time-dependent density functional theory computed difference spectra. The photophysical behaviors of the dyes are altered by the addition of one or two protons. Protonation of basic pyridine nitrogens results in an ultrafast accelerated reversion mechanism after photoisomerization, while protonation of azo bond nitrogens restricts isomer formation entirely.

Windows of Opportunity: How Age and Sex Shape the Influence of Prenatal Depression on the Child Brain.

Maternal prenatal depression can affect child brain and behavioral development. Specifically, altered limbic network structure and function is a likely mechanism through which prenatal depression impacts the life-long mental health of exposed children. While developmental trajectories are influenced by many factors that exacerbate risk or promote resiliency, the role of child age and sex in the relationship between prenatal depression and the child brain remains unclear.

A review of minimal access surgery provision and training within the United Kingdom.

When combined with healthcare pressures, the exponential growth of robotic-assisted surgery (RAS) has impacted UK-based training outcomes, including the learning curve to competency. Aim: To ascertain the current provision of RAS and investigate differences in access to minimal access surgical (MAS) facilities and training across the UK. A two-armed electronic survey was conducted.
