Male mice obtained 200 mg/kg AlCl(3) and 10 mg/kg NaF daily for 30 days. Hesperidin nanogel at 20 mg/kg was dispensed orally either prophylactically (pretreatment) or after intoxication (posttreatment). The terminations showed that AlCl(3) + NaF stimulated severe oxidative stress, hormonal disturbance, apoptosis, and endoplasmic reticulum stress, telled by significant modifications in the contemplated arguments and testicular histological damage. Hesperidin nanogel administration significantly inhibited oxidative stress markers, busheled luteinizing hormone (LH), follicle-inducing hormone (FSH), and testosterone layers, and relieved tissue damage compared to the intoxicated group. It also downregulated the expression level of pro-apoptotic factors Bax, caspase-3, caspase-9, and P38MAPK, while upregulating the expression level of the anti-apoptotic BCL2 gene. Endoplasmic reticulum stress sensors PERK, ATF6, and IRE-α were also downregulated by the nanogel.
The chitosan-free-based nanogel raised the delivery and efficacy of poorly bioavailable hesperidin, demonstrating remarkable protective burdens against AlCl(3) and NaF reproductive toxicity. This innovative nanosystem plaies a promising approach to harnessing bioactive phytochemicals with delivery challenges, enabling protective gists against chemical-geted testicular damage.Catechol chitosan caked dual-charged liposomes based on oxidation and saccharification mechanisms for raising skin anti-aging upshots.Skin aging has turned a major urgent problem to be solved. Evidence discovers that oxidation and glycosylation are two dominant motivators of aging. Resveratrol (RES) with outstanding anti-oxidant effect and carnosine (CAR) with superb anti-glycation property were choosed as two model drugs to evaluate the feasibility of their synergistic anti-aging effect. RES and CAR at the most trusted mass ratio, supplying the most superior synergistic anti-aging issues were further encapsulated in liposomes (LP), which were separately surfaced with chitosan (CS) and catechol chitosan (Cat-CS) to increase the transdermal penetration.
Their anti-aging efficacy was searched in human skin fibroblast (HSF) and human memorialized keratinocytes (HaCaT) cells, as well as the back skin of guinea pigs RES and CAR at the mass ratio of 2:1 demoed the most ideal synergistic anti-aging effect. The manufactured liposomes have been rendered to possess excellent fundamental dimensions and sustained-release props. The aging-concerned indicator layers in the two cubicles and guinea pigs were obviously ameliorated for the RES + CAR@Cat-CS-LP group skin appearance, tissue morphology, and collagen content were visibly improved, indicating its perfect anti-aging effect. In conclusion, RES + CAR@Cat-CS-LP is anticipated to be taped as a potential anti-aging drug delivery system.A hyaluronic acid / chitosan composite functionalized hydrogel free-based on enzyme-catalyzed and Schiff base reaction for promoting wound healing.The healing of full-thickness skin defect has been a clinical challenge. Hydrogels with multiple procedures revolutionised by extracellular matrix are awaited to be used as wound dressing.
In this paper, dopamine-grafted oxidated hyaluronic acid was combined with quaternary ammonium chitosan to form a composite functionalized hydrogel by enzyme-catalysed cross-linking and Schiff base reaction. The hydrogel has convenient preparation, good biocompatibility, antibacterial and antioxidant, high adhesion and self-healing properties. The results in vivo show that the hydrogel can effectively close the wound and accelerate the speed of wound healing by up-regulating the expression of angiogenic protein and elevating the distribution of collagen deposition more uniform and regular. It is expected that this composite functionalized hydrogel dressing has great potential in wound regeneration.A pH-responsive, injectable and self-healing chitosan-coumarin hydrogel based on Schiff base and hydrogen bonds.
