AI Article Synopsis
- Oral hyaluronic acid (HA) has been researched for its potential use in treating various diseases through different formulations based on their average molar mass (MM).
- The study categorized HA into free HA with varying MM and crosslinked nanoparticles, examining their physical properties and mucoadhesion effectiveness.
- Results indicated that f-HA (particularly intermediate MM) and mixed-HA showed better adherence to intestinal mucosa, making them suitable for treating conditions like dysbiosis, while n-HA showed better tissue diffusion.
Article Abstract
Oral hyaluronic acid (HA) is a ubiquitous biopolymer that has gained attention as a treatment for local or systemic diseases. Here, we prepared and characterized structures of free HA (f-HA) with a high (>10 Da), intermediate (≤10 Da), and low (≤10 Da) average molar mass (MM); nanoparticles crosslinked with adipic dihydrazide (n-HA); and mixed formulations (mixed-HA) containing f-HA and n-HA. MM distribution determined the structure, hydrodynamic diameter, and zeta potential of the f-HAs. Crosslinking changed the physicochemical properties in n-HA. In vitro tack adhesion assays, using mucin tablets or a viable rat intestinal mucosa, showed better mucoadhesion with f-HA (intermediate MM) and mixed-HA (25% n-HA), especially in the jejunum segment. High MM f-HA presented negligible mucoadhesion. n-HA showed the deepest diffusion into the porous of the membranes. In vivo results showed that, except for high MM f-HA, there is an inverse relationship between rheological changes in the intestinal membrane macerates resulting from mucoadhesion and the effective intestinal permeability that led to blood clearance of the structures. We conclude that the n-HA formulations are promising for targeting other tissues, while formulations of f-HA (intermediate MM) and mixed-HA are better for treating dysbiosis.

Background: Temple hollowing is characterized by the reduction of volume in the temporal fossa, which can result in a skeletonized look and contribute to an aged appearance. This study aimed to evaluate the safety and effectiveness of the VYC-20L injectable gel for improvement of temple hollowing.
Methods: Adults with minimal, moderate, or severe temple hollows were randomized 2:1 to receive VYC-20L or no treatment.

Background: Aging reduces the production of hyaluronic acid (HA) in the skin, leading to wrinkles and sagging. HA-based skincare products are being studied to improve skin quality. This systematic review and meta-analysis aimed to compare the effectiveness of HA-based injectable products for reducing wrinkles and enhancing skin elasticity, hydration, and radiation.

Background: Tear trough deformities are indicative of aging, progressively manifesting as pronounced infraorbital hollows. Although hyaluronic acid (HA) dermal fillers are favored for their safety and efficacy, quantifiable evidence of their effect of action still remains insufficient.
Aims: To investigate the efficacy of non-cross-linked HA compound in tear trough enhancement.

Periodontal disease stands the leading cause of tooth loss in adults. While scaling and root planning is considered the "gold standard" treatment, it is often insufficient in efficiently eliminating anaerobic bacteria from deep periodontal pockets. In this work, an antibiotic-free and photo-curing hyaluronic acid-Janus (H-Janus) antibacterial pack was developed to inhibit the growth and colonization of residual bacteria within the pockets for reducing the recurrence of periodontitis.

Soft tissue deficiency around dental implants can negatively impact outcomes in terms of esthetics and long-term stability. While autogenous connective tissue grafting is still considered the gold standard treatment, alternative approaches are being proposed primarily to enhance patient comfort and avoid invasive procedures such as two-sites surgeries using xenogeneic collagen matrices. Despite the advantages, the quality of the regenerated tissues remains unpredictable and, in many cases, questionable, highlighting the need for alternative and innovative approaches.
