Summary
New saliva-gels offer a promising, non-invasive treatment for xerostomia (dry mouth). These biocompatible gels control artificial saliva release, mimicking natural saliva for improved oral function.
Area of Science:
- Biomaterials Science
- Drug Delivery Systems
- Oral Medicine
Background:
- Xerostomia significantly impairs swallowing, speech, and oral hygiene.
- Current xerostomia treatments provide only temporary symptom relief.
- There is a need for cost-effective, non-invasive xerostomia solutions.
Purpose of the Study:
- To develop and characterize biocompatible saliva-gels for controlled artificial saliva release.
- To mimic natural saliva release properties for xerostomia management.
- To demonstrate the potential of these gels as a novel xerostomia treatment.
Main Methods:
- Synthesis of acrylamide-based saliva-gels with tailored mechanical properties.
- Investigation of gel swelling behavior in aqueous environments.
- Quantification of artificial saliva release kinetics at 37 °C.
- Chemical analysis of released saliva to confirm identity.
Main Results:
- Saliva-gels exhibited significant swelling (~650% in 3 hours).
- Optimized gels released ~80% of absorbed artificial saliva within 24 hours at 37 °C.
- Released saliva was chemically identical to the initial artificial saliva formulation.
Conclusions:
- Acrylamide-based saliva-gels demonstrate controlled artificial saliva release.
- These gels show potential as a non-invasive, long-term solution for xerostomia.
- The study provides a proof-of-concept for advanced biomaterials in oral health.

01:23Salivary Glands and Saliva
343
The salivary glands, of which there are three pairs known as the parotid, submandibular, and sublingual glands, play a crucial role in maintaining oral health and initiating the digestive process. Positioned near the ears, beneath the masseter muscle, the parotid glands secrete saliva into the oral cavity through the parotid duct of Stensen. Meanwhile, the submandibular glands, located on the floor of the mouth, secrete saliva through channels named submandibular ducts. The sublingual glands,...

01:11Direct-Acting Cholinergic Agonists: Therapeutic Uses
663
Direct-acting cholinergic agonists have many therapeutic uses in various medical fields. Choline esters, including acetylcholine, have limited clinical utility due to their non-selectivity and short duration of action. Still, acetylcholine and carbachol are applied topically during ophthalmologic surgery to induce miosis. Pilocarpine, a muscarinic and ganglionic stimulator, effectively treats open-angle glaucoma and alleviates xerostomia and dry mouth caused by radiotherapy or Sjögren...

01:29Drugs for Treatment of Ulcerative Colitis in IBD
116
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

01:19Oral Hypoglycemic Agents: α-Glucosidase Inhibitors
141
α-glucosidase inhibitors, including acarbose (Precose), miglitol (Glyset), and voglibose (Voglib) (primarily available in Asia), are drugs that control blood sugar levels by delaying the digestion of starch and disaccharides. They achieve this by inhibiting α-glucosidase enzymes in the intestine, which slow the absorption of carbohydrates in the intestine, which in turn leads to a prolonged release of the glucoregulatory hormone GLP-1 from intestinal L-cells.

01:27Chemotherapy-Induced Nausea and Vomiting: 5-HT3 Receptor Antagonists
171
5-HT3 receptor antagonists, such as dolasetron, granisetron (Kytril), ondansetron (Zofran), and palonosetron (Axoli), are crucial in managing chemotherapy-induced nausea and vomiting (CINV) and postoperative nausea. These drugs selectively block 5-HT3 receptors in the visceral vagal and spinal afferent nerves, chemoreceptor trigger zone, and the vomiting center. They have a rapid onset of action and can be given as a single dose before chemotherapy. Ondansetron and granisetron, in particular,...
