CD44 Expression in Oral Lichen Planus and Related Lesions-An Immunohistochemical Study.

Background: Cluster of differentiation 44 (CD44) is a cell surface adhesion protein involved in the progression and metastasis of oral squamous cell carcinoma. The current study aims to evaluate the expression of CD44 in oral lichen planus and related lesions and thereby assess the relative risk of malignant transformation of these lesions.

Materials And Methods: Formalin-fixed paraffin-embedded tissue blocks of 10 oral lichen planus (Group 1), 10 oral lichenoid lesions (Group 2), 8 with oral lichen planus with dysplasia (Group 3), and 5 with lichenoid dysplasia (Group 4) were included in the study.

Finite/fixed-time synchronization of inertial memristive neural networks by interval matrix method for secure communication.

This paper investigates the finite/fixed-time synchronization problem of delayed inertial memristive neural networks (DIMNNs) using interval matrix-based methods within a unified control framework. By employing set-valued mapping and differential inclusion theory, two distinct methods are applied to handle the switching behavior of memristor parameters: the maximum absolute value method and the interval matrix method. Based on these different approaches, two control strategies are proposed to select appropriate control parameters, enabling the system to achieve finite and fixed-time synchronization, respectively.

Finite-time stability analysis and control of stochastic SIR epidemic model: A study of COVID-19.

Finite-time stability analysis is a powerful tool for understanding the long-term behavior of epidemiological models and has been widely used to study the spread of infectious diseases such as COVID-19. In this paper, we present a finite-time stability analysis of a stochastic susceptible-infected-recovered (SIR) epidemic compartmental model with switching signals. The model includes a linear parameter variation (LPV) and switching system that represents the impact of external factors, such as changes in public health policies or seasonal variations, on the transmission rate of the disease.

Alpha-L-fucosidase levels in patients with oral submucous fibrosis and controls: A comparative study.

Background: Oral submucous fibrosis (OSMF) in recent times has been recognized as a potentially malignant disorder (PMD) with an increased risk of developing oral squamous cell carcinoma with malignant transformation rates that vary from 0.6% to 36%. Alpha-L-fucosidase (AFU) is a lysosomal enzyme that is involved in maintaining the homeostasis of fucose metabolism.

Intraoral neurofibroma: A case report with emphasis on immunohistochemical markers.

A neurofibroma is a benign peripheral nerve sheath tumor. They occur in combination with neurofibromatosis or as a solitary mass. Intraoral neurofibromas pose diagnostic difficulties, suggesting the appropriate use of diagnostic markers and clinical knowledge.
