Cerebellopontine angle paraganglioma masquerading as vestibular schwannoma.

Paragangliomas are slow-growing, extra-adrenal neuroendocrine tumors with rare intracranial presentation. Although benign, they can be locally aggressive tumors causing bone destruction and compression related symptoms. We report the case of a 19 years old, normotensive female who presented with headache and vertigo for the past six months.

Ionotronics for reverse actuation.

In the midst of an ongoing energy crisis, the search for new methods of energy harvesting has never been more important. Here we explore, analyse and discuss principles of ionotronic reverse-actuator devices based on the effect of double-layer charging. The designs that we consider in this paper operate based on a common principle - using external mechanical work, which would otherwise be wasted, to produce changes in the contact area of electrode and electrolyte, translated into the time variation of the double-layer capacitance.

Understanding of Future Prescribers About Antimicrobial Resistance and Their Preparedness Towards Antimicrobial Stewardship Activities in Pakistan: Findings and Implications.

Insufficient antimicrobial-related training for physicians during their undergraduate education could have a negative impact on their prescribing. Unlike previous studies, this study not only explored the understanding and perception of Pakistani medical students about antibiotics and resistance, but also their preparedness towards antimicrobial stewardship programs. An online cross-sectional study was undertaken with final-year medical students using a validated questionnaire from January 2021 to May 2021.
