Biomaterial Strategies for Targeted Intracellular Delivery to Phagocytes
Advanced Functional Materials, EarlyView.Phagocytes are essential to a functional immune system, and their behavior defines disease outcomes. Engineered particles offer a strategic opportunity to target phagocytes, harnessing inflammatory modulation in disease. By tuning features like size, shape, and surface, these systems can modulate immune responses and improve targeted treatment for a ...

Advanced Functional Materials, EarlyView.This work presents a soft microelectrode array based on vertically aligned carbon nanotube (CNT) forests, combining high conductivity with mechanical softness. A densification process and air‐pressure‐assisted flexibilization improve structural integrity, ensuring stable insertion and reduced inflammation.

Enzyme‐Regulated Extended Swelling of Hydrogels for Dehiscence‐Less Tissue Expansions
Advanced Functional Materials, EarlyView.An interpenetrating hydrogel network with swelling under regulation by enzymatic degradation (INSURED) is fabricated to avoid dehiscence. INSURED remains structurally intact post‐implantation, while HYAL injection enables control over the onset and rate of swelling.

Advanced Functional Materials, EarlyView.Buckling‐resistant and trace‐stacked (BRATS) intracortical microelectrode arrays (MEAs) eliminate the need for insertion aid and complex surgical setup, resulting in minimal inflammatory tissue response, compared to conventional flexible MEAs inserted with aid. Trace stacking effectively doubled the channel count without increasing the MEA shank width,

LOCAL ANESTHESIA IN GENERAL SURGERY. [PDF]
JAMA: The Journal of the American Medical Association, 1907 During the past few months, in a comparatively small radius, I have known of five deaths directly attributable to general anesthesia. In two instances chloroform was the anesthetizing agent, in two ether and in one somnoform. These represent a relatively small number of cases.

Advanced Functional Materials, EarlyView.This work introduces a novel Hybrid Retinal Implant (HRI), composed of a high‐density electrode array integrated with glutamatergic neurons to overcome key limitations of current retinal prostheses. The significant reduction of activation threshold and of electrode cross‐talk yields in an improved spatial resolution.

The free energy of biomembrane and nerve excitation and the role of anesthetics
, 2018 In the electromechanical theory of nerve stimulation, the nerve impulse consists of a traveling region of solid membrane in a liquid environment. Therefore, the free energy necessary to stimulate a pulse is directly related to the free energy difference ...

PROSTATECTOMY UNDER LOCAL ANESTHESIA [PDF]
Journal of the American Medical Association, 1916 Prostatism presents one of the most frequent dilemmas in the choice of an anesthetic. When the patient is in good condition, a general anesthetic may be administered with impunity; but in those conditions in which the bladder has long been infected, urinary stasis and pyelitis are present with an abundant urine of low specific gravity, and the ...
