Kaempferol-3-O-β-d-glucuronide (K3G) having various pharmacological effects was explored for its anti-inflammatory effect in LPS induced RAW 264.7 cells and mice model. K3G significantly inhibited various pro-inflammatory mediators like IL-1β, NO, PGE2, and LTB4. It upregulated the secretion of anti-inflammatory cytokine IL-10. K3G is found to reduce inflammation when studied for parameters like phagocytic index, carrageenan induced paw edema in mice and organ weight. It reduced inflammation in a dose dependent manner both in-vitro and in-vivo. Further molecular insights into the study reveal that K3G blocks the phosphorylation of NF-kB which is key regulator of inflammation, thereby exhibiting anti-inflammatory potential. Hence, this study permits further investigation to develop K3G as anti-inflammatory drug.

Bacterial infections can induce exuberant immune responses that can damage host tissues. Previously, we demonstrated that systemic infection in mice causes tissue damage in the liver. This liver necrosis is associated with the expression of endogenous retroviruses, chromosomally integrated retroviruses that encode a reverse transcriptase.

Introduction: This work aimed to evaluate the anti-inflammatory and myorelaxant effect of thymol (TM) and carvacrol (CAR) in the pregnant rat uterus. Both compounds exhibit considerable antimicrobial, antispasmodic, and anti-inflammatory effects and due to these properties, they were studied in this in vitro model of premature birth induced by infection.
Method: All uterine tissues were studied in uterine contraction tests to determine the inhibitory effect of TM, CAR (10, 56, 100, 150, and 230 μM), and nifedipine (a calcium channel antagonist) on phasic and tonic contraction induced by electro- and pharmacomechanical stimuli.
A novel technique of cryodenervation for murine vagus nerve: implications for acute lung inflammation.

Background: Neuroimmune interaction is an underestimated mechanism for lung diseases, and cryoablation is a competitive advantageous technique than other non-pharmacologic interventions for peripheral nerve innervating the lung. However, a lack of cryodenervation model in laboratory rodents leads to the obscure mechanisms for techniques used in clinic.
Method: Herein, we developed a novel practical method for mouse peripheral nerve cryoablation, named visualized and simple cryodenervation (VSCD).

Maejo 341 Sweet potato (MSP) is a new purple sweet potato variety cultivated in Northern Thailand, but its health benefits are unknown. This study aimed to investigate its antioxidant, anti-inflammatory, and anti-osteoporotic activities, as well as its anthocyanin content. The peel and flesh of MSP were extracted with ethanol and water.

Enhanced inflammatory and immune responses have been observed in patients with major depressive disorder, pointing to anti-inflammatory substances as potential seeds for developing novel antidepressants. Omega-3 polyunsaturated fatty acid metabolites, such as resolvin D and E series, maresins, and protectins (collectively known as specialized pro-resolving mediators) demonstrate anti-inflammatory effects. This study examined the antidepressant-like effects of maresin-1 (MaR1) on lipopolysaccharide (LPS)-induced depression-like behaviors in mice.
