Ultra‐Fine 3D Bioprinting of Dynamic Hyaluronic Acid Hydrogel for in Vitro Modeling

open access: yesAdvanced Materials, EarlyView.
3D bioprinting merges tissue engineering and additive manufacturing to create biological structures. A bioink is developed by modifying hyaluronic acid, a natural extracellular matrix polymer, with cysteine. Potassium iodide is later added to tune gelation kinetics, enabling fine printing with a 32G needle.

Multiplicative functions commutable with binary quadratic forms $x^2 \pm xy + y^2$ [PDF]

open access: yesarXiv, 2022
If a multiplicative function $f$ is commutable with a quadratic form $x^2+xy+y^2$, i.e., \[ f(x^2+xy+y^2) = f(x)^2 + f(x)\,f(y) + f(y)^2, \] then $f$ is the identity function. In other hand, if $f$ is commutable with a quadratic form $x^2-xy+y^2$, then $f$ is one of three kinds of functions: the identity function, the constant function, and an ...

Nanostructured 316L Stainless Steel Stent Surfaces Improve Corrosion Resistance, and Enhance Endothelization and Hemocompatibility

open access: yesAdvanced Materials Interfaces, EarlyView.
This study investigates the impact of nanostructured surface modification on corrosion resistance, HUVEC functions, and platelet interactions of 316L SS for cardiovascular stents. Nanostructured surfaces enhanced HUVEC proliferation, migration, and angiogenesis‐related gene expression while reducing platelet adhesion and hemolysis.

Ascorbic acid enhances the inhibitory effect of aspirin on neuronal cyclooxygenase-2-mediated prostaglandin E2 production [PDF]

open access: yesJournal of Neuroimmunology 174(1-2): 39-51 (2006), 2007
In the present study, we show that ascorbic acid dose-dependently inhibited interleukin-1beta (IL-1beta)-mediated PGE2 synthesis in the human neuronal cell line, SK-N-SH. Furthermore, in combination with aspirin, ascorbic acid augmented the inhibitory effect of aspirin on PGE2 synthesis. However, ascorbic acid had no synergistic effect along with other

Differences in central actions of arachidonic acid and prostaglandin F\(_{2\alpha}\) between spontaneously hypertensive and normotensive rats [PDF]

open access: yes, 1982
Prostag1andin F\(_{2\alpha}\) (PGF\(_{2\alpha}\)) is one of the most common metabo1ites of arachidonic acid (M) in rat brain. When administered intracerebroventricularly (i.c.v.) to rats, both AA and PGFal exert dose-related hypertensive, tachycardic and

Aspirin inhibits the acute venodilator response to furosemide in patients with chronic heart failure [PDF]

open access: yes, 2001
OBJECTIVES: We sought to determine the effect of aspirin on the venodilator effect of furosemide in patients with chronic heart failure (CHF) BACKGROUND: Furosemide has an acute venodilator effect preceding its diuretic action, which is blocked

Achieving Optimal Health With Host‐Directed Therapies (HDTs) in Infectious Diseases—A New Horizon

open access: yesAdvanced Therapeutics, Volume 8, Issue 4, April 2025.
Host‐directed therapies (HDTs) represent a transformative approach in infectious disease management by targeting host factors to enhance immune responses and inhibit viral replication. This innovative strategy leverages advanced genomics and gene editing technologies, offering promising avenues for improved patient outcomes and a new horizon in ...

Uniformly bounded components of normality [PDF]

open access: yes, 2007
Suppose that $f(z)$ is a transcendental entire function and that the Fatou set $F(f)\neq\emptyset$. Set $$B_1(f):=\sup_{U}\frac{\sup_{z\in U}\log(|z|+3)}{\inf_{w\in U}\log(|w|+3)}$$ and $$B_2(f):=\sup_{U}\frac{\sup_{z\in U}\log\log(|z|+30)}{\inf_{w\in U}\log(|w|+3)},$$ where the supremum $\sup_{U}$ is taken over all components of $F(f)$.

Bee Better: The Role of Honey in Modern Wound Care

open access: yesAdvanced Therapeutics, Volume 8, Issue 5, May 2025.
The use of honey as a wound care agent is controversial but paradoxically increasingly popular. Honey possesses relevant antimicrobial properties and can modulate the immune system. The wound healing properties of honey likely depend on its composition and varies across wound types.
