Biphasic Cuirass Ventilation for Airway Surgeries: A Comprehensive Review.

Airway surgeries pose great challenges for the anesthesiologists as the airway is shared by them and the surgeon. It is of paramount importance to have control of the airway during such surgeries. Many techniques have been employed to provide uninterrupted oxygenation to the patient with or without the presence of a definitive airway.

Medical Gaze Sans Bioethics: Revisiting Enslaved Black Women's Medical Bondage in Behind the Sheet.

The birth of modern gynecology in the USA is preceded by experimental exploitations of Black women's bodies in the mid-nineteenth century, entailing a long-drawn extraction of "reproductive knowledge" from enslaved patients. Charly Evon Simpson's Behind the Sheet (2019) stages the history of medical bondage of Black enslaved women in antebellum South, reconstructing the events that led to the surgical innovation for vesico-vaginal fistula. Scrutinizing Simpson's dramatization of the event, this paper prompts inquiries into the interplay of power and consent between the physician and the enslaved patient in plantation healthcare, highlighting the need to reexamine bioethical principles.

Blurring Boundaries: A Proposed Research Agenda for Ethical, Legal, Social, and Historical Studies at the Intersection of Infectious and Genetic Disease.

Contemporary understanding of the mechanisms of disease increasingly points to examples of "genetic diseases" with an infectious component and of "infectious diseases" with a genetic component. Such blurred boundaries generate ethical, legal, and social issues and highlight historical contexts that must be examined when incorporating host genomic information into the prevention, outbreak control, and treatment of infectious diseases.

Enhancing Ultradeep Hydrodesulfurization of Coker Diesel through Adsorptive Predenitrogenation.

The petroleum refining industry places significant challenge in the production of ultralow-sulfur diesel (ULSD) from various middle distillates with high nitrogen concentration in an energy-efficient and cost-effective way to meet strict environmental regulations as coexisting nitrogen compounds significantly inhibit the ultradeep hydrodesulfurization (HDS). Among all of the approaches reported in the literature for this challenge, a combination of adsorptive denitrogenation (ADN) and HDS has attracted great attention. This study focuses on ultradeep HDS of coker diesel (CD) through a synergistic approach combining ADN over a carbon-based adsorbent and the current HDS process.
