Article Synopsis
  • Glycoproteins, which play a key role in cell functions, include L-fucose; recent studies suggest that serum L-fucose could be an early indicator for detecting malignancies, particularly in patients with oral submucous fibrosis (OSMF).
  • This research aimed to assess the potential of serum L-fucose as a diagnostic biomarker for dysplasia in OSMF patients through a two-year study involving 80 subjects.
  • Results indicated a significant difference in serum L-fucose levels between OSMF patients with and without dysplasia, suggesting that elevated levels may help identify precancerous conditions linked to harmful habits like gutkha chewing.

Background: Epidermolysis bullosa (EB) is a genetic syndrome afflicting skin and mucous membranes. The manifestation depends on the form: in mild conditions, occasionally, vesicular-bullous lesions of the oral cavity may be present, which heal spontaneously without leaving scars. Patients following joint rupture have scars that limit food intake and restrict quality of life.

Background: The Herbst appliance is an excellent therapy for treating class II malocclusions with increased overjet. Its mechanics involve propelling the mandibular bone using two pistons the patient cannot remove. The so-called bite-jumping keeps the mandible in a more anterior position for a variable period, usually at least 6 months.

Pain-Free Alpha-Synuclein Detection by Low-Cost Hierarchical Nanowire Based Electrode.

Nanomaterials (Basel)

January 2024

Department of Physics and Astronomy, University of Catania, "Ettore Majorana", Via Santa Sofia 64, 95123 Catania, Italy.

Analytical methods for the early detection of the neurodegenerative biomarker for Parkinson's disease (PD), α-synuclein, are time-consuming and invasive, and require skilled personnel and sophisticated and expensive equipment. Thus, a pain-free, prompt and simple α-synuclein biosensor for detection in plasma is highly demanded. In this paper, an α-synuclein electrochemical biosensor based on hierarchical polyglutamic acid/ZnO nanowires decorated by gold nanoparticles, assembled as nanostars (NSs), for the determination of α-synuclein in human plasma is proposed.
