Опубликована: Ноя. 5, 2021

Non-alcoholic fatty liver disease (NAFLD) includes a range of hepatic manifestations, starting with steatosis and potentially evolving towards non-alcoholic steatohepatitis (NASH), cirrhosis or even hepatocellular carcinoma. NAFLD is major health burden, its incidence increasing worldwide. Although it primarily disturbed metabolism, involves several immune cell-mediated inflammatory processes, particularly when reaching the stage NASH, at which point inflammation becomes integral to progression disease. The cell landscape diverse steady state further evolves during NASH direct consequences for severity. In this Review, we discuss current concepts related role cells in onset NASH. A better understanding mechanisms by contribute pathogenesis should aid design innovative drugs target therapeutic options are limited.

Obesity is a chronic disease with high prevalence and associated comorbidities, making it growing global concern. These comorbidities include type 2 diabetes, hypertension, ventilatory dysfunction, arthrosis, venous lymphatic circulation diseases, depression, others, which have negative impact on health increase morbidity mortality. GLP-1 agonists, used to treat been shown be effective in promoting weight loss preclinical clinical studies. This review summarizes numerous studies conducted the main drugs agonists class, outlining maximum achievable loss. Our aim emphasize active role outcomes of loss, as well improving hyperglycemia, insulin sensitivity, blood pressure, cardio–metabolic, renal protection. We highlight pleiotropic effects these medications, along their indications, contraindications, precautions for both diabetic non-diabetic patients, based long-term follow-up

Entomophagy describes the practice of eating insects. Insects are considered extremely nutritious in many countries worldwide. However, there is a lethargic uptake this Europe where consuming insects and insect-based foodstuffs often regarded with disgust. Such perceptions concerns due to lack exposure availability food-grade as food source driven by neophobia cultural norms. In recent years, accelerating climate change, an urgency develop alternate safe sustainable food-sources has emerged. There currently over 2000 species approved World Health Organization eat suitable for human consumption. This review article provides updated overview potential edible safe, palatable, source. Furthermore, legislation, safety issues, nutritional composition invertebrates including, but not limited, crickets (Orthoptera) mealworms (Coleoptera) also explored within review. discusses insect farming methods upscaling industry regard future prospects Finally, topics addressed areas concern current consumers

Self‐Assembled Oligopeptoplex‐Loaded Dissolving Microneedles for Adipocyte‐Targeted Anti‐Obesity Gene Therapy

Advanced Materials, Год журнала: 2024, Номер 36(16)

Опубликована: Янв. 11, 2024

Abstract Advancements in gene delivery systems are pivotal for gene‐based therapeutics oncological, inflammatory, and infectious diseases. This study delineates the design of a self‐assembled oligopeptoplex (SA‐OP) optimized shRNA to adipocytes, targeting obesity associated metabolic syndromes. Conventional face challenges, including instability due electrostatic interactions between genetic materials cationic oligopeptides. Additionally, repeated injections induce discomfort compromise patient well‐being. To circumvent these issues, dissolvable hyaluronic acid‐based, self‐locking microneedle (LMN) patch is developed, with improved micro‐dose efficiency, precise SA‐OP delivery. platform offers pain‐free administration storage stability. In vitro studies 3T3‐L1 cells demonstrated improvements preservation silencing efficacy. vivo evaluation mice model diet‐induced type 2 diabetes yielded significant adipose tissue 21.92 ± 2.51% reduction body weight minimum relapse risk at 6‐weeks post‐treatment, representing superior therapeutic efficacy truncated timeframe relative GLP‐1 analogues currently available on market. mitigated insulin resistance, inflammation, hepatic steatosis. These findings establish as robust, minimally invasive transdermal prolonged stability treating its comorbidities.

Type 2 diabetes mellitus (T2DM) is usually complicated by cardiovascular diseases, hyperglycemia, and obesity, which worsen the outcome for patient. Since recent evidence underlines epigenetic role of glucagon-like peptide-1 receptor agonists (GLP-1RAs) in management these comorbidities, this study compared effects agents, namely liraglutide, semaglutide, dulaglutide, exenatide, on miRNA regulation T2DM. GLP-1RAs modify expression miRNAs involved endothelial function, sugar metabolism, adipogenesis, including but not limited to miR-27b, miR-130a, miR-210. Baseline miR-15a-5p predict weight loss, while higher miR-378-3p miR-126-3p levels are related better glycemic control lower HbA1c FPG at one year post-treatment. miR-375-5p was also reported as a predictor levels. Liraglutide has protecting effect against pancreatic β-cell apoptosis downregulating miR-139-5p.

Abstract Obesity is a highly prevalent chronic multisystem disease associated with shortened life expectancy due to number of adverse health outcomes. Epidemiological data link body weight and parameters central fat distribution an increasing risk for type 2 diabetes, hypertension, fatty liver diseases, cardiovascular diseases including myocardial infarction, heart failure, atrial fibrillation, stroke, obstructive sleep apnoea, osteoarthritis, mental disorders some types cancer. However, the individual develop cardiometabolic other obesity‐related cannot entirely be explained by increased mass. Rather than excess accumulation, dysfunction adipose tissue may represent mechanistic between obesity There are people living who seem protected against premature development diseases. On hand, normal typical upon predominantly visceral distribution. The mechanisms linking impaired function in include adipocyte hypertrophy, altered cellular composition, limited expandability safe subcutaneous stores, ectopic deposition depots, organs, hypoxia, variety stresses, inflammatory processes, release pro‐inflammatory, diabetogenic atherogenic signals. Genetic environmental factors might contribute either alone or via interaction intrinsic biological variation function. still many open questions regarding how causes whether these pathologies could reversed.

The prevalence of obesity continues to rise worldwide despite evidence-based public health recommendations. promise adopt a healthy lifestyle is increasingly important for tackling this global epidemic. Calorie restriction or regular exercise combination the two accepted as an effective strategy in preventing treating obesity. Furthermore, benefits conferred by overcome are attributed not only reduced adiposity levels circulating lipids but also proteins, peptides, enzymes, and metabolites that released from contracting skeletal muscle other organs. secretion these molecules called cytokines response induces browning white adipose tissue increasing expression brown adipocyte-specific genes within tissue, suggesting exercise-induced may play significant role In review, we present research-based evidence supporting effects various diet interventions on health. We discuss interplay between secreted organs known affect metabolism.
