RESUMEN

Propolis is rich in natural bioactive compounds, and considering its importance for many skin therapies, emulgel was prepared. This study examines how a propolis extract (PE) and Passiflora edulis seed (PS) oil emulgel affect rat deep skin wound healing. Based on preset criteria of maximum drug content and optimum drug permeation through the stratum corneum along with drug retention in the skin layers, an optimized emulgel formula based on Box-Behnken factorial design was prepared and used for subsequent in vitro and in vivo evaluations. In vivo wound-healing activities of emulgel and control treatments were investigated in a rat model. The optimized emulgel formula exhibited superior healing activity compared with plain PE suspension-treated rats on day 14 of wounding. Histopathological investigations of hematoxylin and eosin and Masson's Trichrome-stained skin sections supported this effect. Emulgel promotes cutaneous wound healing through a variety of mechanisms, including anti-inflammatory through modulation of cytokines tumor necrosis factor-α, interleukin (IL)-1ß, and IL-6 production, and promotion of collagen fiber formation, all of which contribute to tissue remodeling. Furthermore, when compared with propolis suspension, emulgel showed significant antioxidant and anti-inflammatory effects. Emulgel significantly increased the skin's hydroxyproline level, antioxidant potential, wound contraction, increased penetration, and localized propolis deposition across the skin. Incorporation of PS oil into the emulgel accelerates the tissue regeneration process. The findings suggest that 5% propolis emulgel could be used as an alternative to treat wounds.

RESUMEN

Psoriasis is an autoimmune skin disorder that is characterised by chronic inflammation and erythematous scaly patches. It has a significant impact on the patient's quality of life and can cause psychological stress. There are several aspects that cause psoriasis, for instance, environmental issues, immune disorders, bacterial infections, and genetic issues. Plentiful therapeutic means or treatments are accessible, but not any of them can completely and effectively cure psoriasis without hindering patient compliance. Hence, it becomes challenging to discover a new drug moiety or any drug delivery method to cure psoriasis. Conventional treatment of psoriasis involves anti-inflammatory agents, immune suppressants, phototherapy, and biological treatment, which were given in different forms such as topical, oral, or systemic formulations, but these all were unsuccessful to accomplish complete reduction of psoriasis as well as causing adverse side effects. In terms of dose frequency, doses, efficacy, and side effects, nanotechnology-based new formulations are the most promising prospects for addressing the challenges and limits associated with present psoriasis formulations. Hence, our major goal of this review is to present various advanced nanotechnological approaches for the effective topical treatment of psoriasis. In short, nano-formulations continue to be formed as very promising modalities in the treatment of psoriasis as they suggest improved penetration, targeted delivery, increased safety, and efficacy.

RESUMEN

Dengue fever is prevalent in subtopic regions, producing mortality and morbidity worldwide, which have been of major concern to different governments and World Health Organization. The search of new anti-dengue agents from phytochemicals was assumed to be highly emergent in past. The phytochemicals have been used in wide distribution of vector ailments such as malaria. The demand of the phytochemicals is based on the medicines which are mostly considered to be safer, less harmful than synthetic drugs and nontoxic. This review mentions majorly about the phytochemicals potentially inhibiting dengue fever around the world. The phytochemicals have been isolated from different species, have potential for the treatment of dengue. Different crude extracts and essential oils obtained from different species showed a broad activity against different phytochemicals. The current studies showed that natural products represent a rich source of medicines toward the dengue fever. Furthermore, ethnobotanical surveys and laboratory investigation established identified natural plants species in the development of drug discovery to control the dengue fever.

RESUMEN

L-asparaginase (L-asparagine amidohydrolase EC 3.5.1.1) is of great importance in pharmaceutical and food applications. This review aims to describe the production and use of fungal L-asparaginase focusing on its potential as an effective reducer of acrylamide in different food applications. Fungal asparaginases have been used as food additives and have gained importance due to some technical advantages, for example, fungi can grow using low-cost culture mediums, and the enzyme is extracellular, which facilitates purification steps. Research aimed at the discovery of new L-asparaginases, mainly those produced by fungi, have great potential to obtain cheaper enzymes with desirable properties for application in food aiming at the reduction of acrylamide.
