Proteins and Peptides Studied In Silico and In Vivo for the Treatment of Diabetes Mellitus: A Systematic Review.

Bioinformatics has expedited the screening of new efficient therapeutic agents for diseases such as diabetes mellitus (DM). The objective of this systematic review (SR) was to understand naturally occurring proteins and peptides studied in silico and subsequently reevaluated in vivo for treating DM, guided by the question: which peptides or proteins have been studied in silico for the treatment of diabetes mellitus? The RS protocol was registered in the International Prospective Register of Systematic Reviews database. Articles meeting the eligibility criteria were selected from the PubMed, ScienceDirect, Scopus, Web of Science, Virtual Health Library (VHL), and EMBASE databases.

Assessment of acute toxicity of crude extract rich in carotenoids from Cantaloupe melon (Cucumis melo L.) and the gelatin-based nanoparticles using the zebrafish (Danio rerio) model.

The present study investigated the effect of gelatin-based nanoparticles (EPG) loaded with a carotenoid-rich crude extract (CE) on systemic and adipose tissue inflammatory response in a model with inflammation induced by a high glycemic index and high glycemic load diet (HGLI). Nanoparticles synthesized were characterized by different physical and chemical methods. The in vivo investigation evaluated Wistar rats (n = 20, 11 days, adult male with 21 weeks) subdivided into untreated (HGLI diet), conventional treatment (nutritionally adequate diet), treatment 1 (HGLI + crude extract (12.

In silico structure-based design of peptides or proteins as therapeutic tools for obesity or diabetes mellitus: A protocol for systematic review and meta analysis.

Background: In silico studies using dynamic simulation or molecular docking have boosted the screening and identification of molecules and/or targets in studies aimed at treating diseases such as obesity and diabetes mellitus, optimizing the development of new drugs. This study aims to describe a systematic review protocol on peptides and proteins evaluated in silico as potential therapeutic agents for obesity or diabetes mellitus.

Methods: This protocol followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses Protocols and was registered in the International Prospective Register of Systematic Reviews database (number: CRD42022355540).

In silico structure-based designers of therapeutic targets for diabetes mellitus or obesity: A protocol for systematic review.

Obesity is a significant risk factor for several chronic non-communicable diseases, being closely related to Diabetes Mellitus. Computer modeling techniques favor the understanding of interaction mechanisms between specific targets and substances of interest, optimizing drug development. In this article, the protocol of two protocols of systematic reviews are described for identifying therapeutic targets and models for treating obesity or diabetes mellitus investigated in silico.

Nanoparticles Containing Tamarind Isolate Protein Potentiate the Satiety without Promoting the Anti-Inflammatory Effect in a Preclinical Model of Diet-Induced Obesity.

The study aimed to evaluate the nanoparticles (ECW) containing tamarind trypsin inhibitor (TTI) concerning the storage effect under different conditions on antitrypsin activity and the bioactive potential in a preclinical model. ECW was exposed to different pH and temperatures to evaluate the interaction between TTI and its encapsulating agents, monitored by antitrypsin activity. Wistar rats (n = 25) with obesity induced by diet were divided into groups: untreated; treatment with nutritionally adequate diet; treatment with nutritionally adequate diet and ECW/12.

Encapsulation techniques perfect the antioxidant action of carotenoids: A systematic review of how this effect is promoted.

Considering that antioxidant activities are directly related to carotenoid functionalities, it is necessary to use techniques that promote the stability of these natural pigments. This systematic review aimed to gather evidence on the effect of encapsulation techniques on the maintenance and/or enhancement of the antioxidant activity of carotenoids. The study was registered in PROSPERO (CRD42020142065).

Introduction:: Obesity and coronavirus disease (COVID)-19 are overlapping pandemics, and one might worsen the other.

Methods:: This narrative review discusses one of the primary mechanisms to initiate acute respiratory distress syndrome, uncontrolled systemic inflammation in COVID-19, and presents a potential candidate for adjuvant treatment. Blocking the S protein binding to angiotensin-converting enzyme 2 (ACE-2) and the 3C-like protease (3CL ) is an effective strategy against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Antioxidant stability enhancement of carotenoid rich-extract from Cantaloupe melon (Cucumis melo L.) nanoencapsulated in gelatin under different storage conditions.

The study evaluated the potential and antioxidant stability of nanoencapsulated carotenoid-rich extract (CE) from Cantaloupe melon (EPG). DPPH and ABTS radical scavenging assays were used to investigate the nanoencapsulation effect on antioxidant potential. CE and EPG stability were evaluated at 25 °C and 5 °C, with and without light (1600 lx) for 60 days, determining the β-carotene concentration by UHPLC and antioxidant potential by ABTS.

Gelatin nanoparticles enable water dispersibility and potentialize the antimicrobial activity of Buriti (Mauritia flexuosa) oil.

Background: Buriti oil presents numerous health benefits, but due to its lipophilic nature and high oxidation, it is impossible to incorporate it into aqueous food matrices. Thus, the present study evaluated whether powder nanoparticles based on porcine gelatin (OPG) and in combination with sodium alginate (OAG) containing buriti oil obtained by O/W emulsification followed by freeze-drying enabled water dispersibility and preserved or increased the antimicrobial activity of the oil.

Results: OPG presented spherical shape, smooth surface, smaller particle size and polydispersity index [51.

Effect of carotenoid encapsulation on antioxidant activities: A protocol for systematic review.

Background: Carotenoids play essential roles in human health, such as antioxidant activity, and therefore can decrease free radicals oxidation action, preventing numerous diseases. However, these compounds have an unstable nature, turning them susceptible to adverse conditions in food processing and storage. Thereby the search for alternatives that maintain and enhance carotenoid antioxidant function, such as encapsulation, has grown.
