Phoretic flow induced by asymmetric confinement [PDF]

open access: yesJ. Fluid Mech. 799, R5 (2016), 2016
Internal phoretic flows due to the interactions of solid boundaries with local chemical gradients may be created using chemical patterning. Alternatively, we demonstrate here that internal flows might also be induced by geometric asymmetries of chemically-homogeneous surfaces.

Pediatric Shock [PDF]

open access: yes, 2008
Millions of children die of shock due to various etiologies each year. Shock is a state of circulatory dysfunction where the metabolic demands of the tissue cannot be met by the circulation.

Precision Photothermal Therapy at Mild Temperature: NIR‐II Imaging‐Guided, H2O2‐Responsive Stealth Nanobomb

open access: yesAdvanced Healthcare Materials, EarlyView.
The new generation nanobomb, termed the stealth nanobomb, is fabricated through self‐assembly using a polymeric carbon monoxide carrier (PLGA(CO)), small molecule near‐infrared‐active agents (2TT‐OC46B), and phospholipid polyethylene glycol (DSPE‐mPEG2000). The stealth nanobomb can circulate in the bloodstream and specifically target pancreatic cancer,

PAF‐induced inflammatory and immuno‐allergic ophthalmic diseases and their mitigation with PAF receptor antagonists: Cell and nuclear effects

open access: yesBioFactors, Volume 48, Issue 6, Page 1226-1249, November/December 2022., 2022
Abstract Ocular allergies are becoming more prevalent as more airborne pollutants, irritants and microbes pervade our environment. Inflammatory and allergic mediators released by dendritic and mast cells within the conjunctiva cause allergic conjunctivitis (AC), a prevalent ocular surface disorder that affects >40% of the world's human population on a ...

On the estimation of time dependent lift of a European Starling during flapping [PDF]

open access: yes, 2015
We study the role of unsteady lift in the context of flapping wings in birds' flight. Both aerodynamicists and biologists attempt to address this subject, yet it seems that the contribution of the unsteady lift still holds many open questions. The current study deals with the estimation of unsteady aerodynamic forces on a freely flying bird through ...

The Unsteady Lift Produced by a Flat-Plate Wing Translating Past Finite Obstacles [PDF]

open access: yesarXiv, 2023
The unsteady lift of a high-angle-of-attack, flat-plate wing encountering finite-length obstacles is studied using towing-tank force measurements. The wing translates from rest and interacts with a rectangular channel, ceiling, or ground obstacle. Variations with angle of attack, obstacle length, mid-chord height to the obstacle, and starting distance ...

Rotary mechanical circulatory support systems [PDF]

open access: yesJournal of Rehabilitation and Assistive Technologies Engineering. 2017;4:1-24, 2017
A detailed survey of the current trends and recent advances in rotary mechanical circulatory support systems is presented in this paper. Rather than clinical reports, the focus is on technological aspects of these rehabilitating devices as a reference for engineers and biomedical researchers.

Pharmacologic agents for acute hemodynamic instability: Recent advances in the management of perioperative shock- A systematic review

open access: yesAnnals of Cardiac Anaesthesia, 2015
Despite the growing body of evidence evaluating the efficacy of vasoactive agents in the management of hemodynamic instability and circulatory shock, it appears no agent is superior. This is becoming increasingly accepted as current guidelines are moving

Inorganic Nanomaterials Meet the Immune System: An Intricate Balance

open access: yesAdvanced Healthcare Materials, EarlyView.
Metal nanomaterials influence the immune responses, such as cytokine production and T‐cell activity. Unintended immune modulation can have significant consequences while its fine‐tuning may transform the oncology care. Within this review, a critical analysis is offered regarding the nano/immune‐interaction and suggests the future research directions to

The role of PAF in immunopathology: From immediate hypersensitivity reactions to fungal defense

open access: yesBioFactors, Volume 48, Issue 6, Page 1217-1225, November/December 2022., 2022
Abstract Platelet‐activating factor (PAF, 1‐alkyl‐2‐acetyl‐sn‐glycero‐3‐phosphorylcholine) was discovered when the mechanisms involved in the deposition of immune complex in tissues were being scrutinized in the experimental model of rabbit serum sickness.
