Matrix metalloproteinases are shown to be involved in the pathogenesis of tuberculosis inflammation. In the early stages of BCG-granuloma formation in mouse liver and lungs, the serum levels of matrix metalloproteinases 2 and 7 increased by 4.5 times and remained unchanged while the pathology developed. Antimycobacterial therapy with isoniazid reduced enzyme activity almost to the level of intact control. The decrease in activity of matrix metalloproteinases 2 and 7 that play the most prominent role in the development of destructive forms of tuberculosis is of great therapeutic importance.

The use of genetically diverse mouse models offers a more accurate reflection of human genetic variability, improving the translatability of findings to heterogeneous human populations. This approach is particularly valuable in understanding diverse immune responses to disease by environmental exposures. This study investigates the inflammatory responses to acute exposures to mainstream cigarette smoke (CS) and environmental tobacco smoke (ETS) in two genetically diverse mouse strains, CC002/UncJ (UNC) & Diversity Outbred (J:DO).

Purpose: Pachyman, derived from Poria cocos, has been used to treat gouty arthritis (GA) for thousands of years, although its precise role and mechanisms remain unclear. Herein, we investigate the therapeutic effects of pachyman on GA and explore their underlying mechanisms.
Methods: Network pharmacology and experimental methods were employed to investigate the therapeutic mechanisms of pachyman against GA.

Bifenthrin (BFN) is a noxious insecticide which is reported to damage various body organs. Daidzein (DZN) is a natural flavone with excellent pharmacological properties. This research was conducted to evaluate the alleviative strength of DZN to counteract BFN prompted liver toxicity in male albino rats.

The aim was to study the effect of 4-phenylfuroxan-3-carbonitrile (Fx), a NO-releasing agent, and carbetocin, an oxytocin receptor agonist, on matrix metalloproteinases-2 (MMP-2) activity and PGE2 production in cervix from cycling sheep. Cervical explants were incubated during 12 h with MEM supplemented with increasing concentrations of Fx in DMSO (2 %) (0 to 300 μg/mL) with Cb (100 ng/mL) (Experiment 1, n = 15) and DMSO (2 %), DMSO + Cb (100 ng/mL) or DMSO + Fx (30 μg/mL) (Experiment 2, n = 10), and their respective controls. In the supernatants, activated (A) and latent (L) MMP-2 activities were determined by a SDS-PAGE zymography, PGE2 concentration by immunoassay and NO production indirectly as nitrites by spectrophotometry.

Chronic periodontitis is a prevalent inflammatory condition that affects both the oral health and systemic well-being of individuals, particularly those with type 2 diabetes mellitus (T2DM). Accurate diagnosis and evaluation of periodontal status are crucial for effective management of the disease. This narrative review aimed to compare the diagnostic and evaluative capabilities of conventional periodontal probing and salivary biomarkers in chronic periodontitis among individuals with T2DM.
