Advanced Science, EarlyView.Hypothalamus sympathetic norepinephrine inhibits regeneration of articular cartilage. Mechanical loading on bone during animal activity elevates PGE2 skeletal interoception to promote an anabolic renewal of the superficial membrane by downregulation of norepinephrine for articular cartilage proper thickness and integrity.

Almost perfect nonlinear power functions with exponents expressed as fractions [PDF]
arXiv, 2023 Let $F$ be a finite field, let $f$ be a function from $F$ to $F$, and let $a$ be a nonzero element of $F$. The discrete derivative of $f$ in direction $a$ is $\Delta_a f \colon F \to F$ with $(\Delta_a f)(x)=f(x+a)-f(x)$. The differential spectrum of $f$ is the multiset of cardinalities of all the fibers of all the derivatives $\Delta_a f$ as $a$ runs ...

Mechanical Biomimetic Nanocomposites for Multidimensional Treatment of Arterial Thrombosis
Advanced Science, EarlyView.In this study, a mechanical biomimetic nanocomposite is developed, guided by photoacoustic imaging, to achieve highly efficient and safe thrombolysis through the synergistic effects of photothermal therapy and pharmacological intervention. Most notably, the nanoparticle improves the microenvironment of arterial thrombi, marked by high shear stress and ...

Regional distribution of the prostaglandin E2 receptor EP1 in the rat brain: accumulation in Purkinje cells of the cerebellum [PDF]
Journal of Molecular Neuroscience 27(3): 303-310 (2005), 2007 Prostaglandin E2 (PGE2), is a major prostanoid produced by the activity of cyclooxygenases (COX) in response to various physiological and pathological stimuli. PGE2 exerts its effects by activating four specific E-type prostanoid receptors (EP1, EP2, EP3, and EP4).

Induced Turán problems and traces of hypergraphs [PDF]
arXiv, 2020 Let $F$ be a graph. We say that a hypergraph $H$ contains an induced Berge $F$ if the vertices of $F$ can be embedded to $H$ (e.g., $V(F)\subseteq V(H)$) and there exists an injective mapping $f$ from the edges of $F$ to the hyperedges of $H$ such that $f(xy) \cap V(F) = \{x,y\}$ holds for each edge $xy$ of $F$.

Prostaglandin E and F receptors in the uterus
Receptors & Clinical Investigation, 2014 Prostaglandins (PGs) are necessary for normal female reproduction. PGs act via their respective receptors and execute various functions in their target tissues depending on which type of receptor being activated. PG receptors are G-protein coupled receptors mediating various vital processes in the uterus throughout the reproductive cycle and pregnancy.

Parturition and Recruitment of Macrophages in Cervix of Mice Lacking the Prostaglandin F Receptor1
Biology of Reproduction, 2008 Parturition does not occur in transgenic mice lacking the prostaglandin F receptor (Ptgfr−/−) because luteolysis is forestalled and progesterone production persists. Ovariectomy of pregnant Ptgfr−/− mice leads to a decline in circulating progesterone and

AGING MEDICINE, EarlyView.Pogostemon cablin Benth. (PCEE) is a promising antiaging agent that inhibits ROS, decreases the senescence‐associated β‐galactosidase (SA‐β‐gal) gene, and maintains telomere length in doxorubicin‐induced 3T3‐L1 fibroblast cells. The researchers extend their gratitude to www.freepik.com for providing Figure telomer.
