Introduction: The study aims to investigate the antifungal efficacy of albedo extract of Punica grantum on candida albicans by evaluating the inhibitory capacity of alcoholic albedo extracts by disc diffusion method and by comparing the antifungal efficacy of alcoholic extract of albedo with clotrimazole and ethanol.

Methods: Using a conventional disc diffusion method, the effectiveness of Punica Granatum albedo extract against Candida albicans was assessed and evaluated depending on the presence or absence of inhibition zones, as well as the average diameter of inhibition zones. Albedo extract of Punica granatum serial dilutions were prepared ranging from 1%, 5%, 10%, 15%, 20% and 25% and its antifungal efficacy was tested against Candida albicans in comparison with clotrimazole and ethanol.

Periodontitis and oral squamous cell carcinoma (OSCC) are prevalent oral diseases with distinct etiologies, yet they share certain molecular and biological characteristics. Gene expression datasets from the gene expression omnibus (GEO) repository (GSE30784 for OSCC and GSE10334 for periodontitis) were analyzed. Data preprocessing and differential gene expression analysis using GEO2R identified common differentially expressed genes (DEGs), and FunRich software facilitated the construction of a protein-protein interaction (PPI) network on the STRING database.

Context: Glucose uptake may be considered the rate-limiting step for the growth and metabolism of the cancer cell. Studies on GLUT1 have shown that GLUT1 is involved in cell survival and proliferation in both healthy and pathological circumstances. GLUT1 expression is regarded as one of the crucial elements in the development of local aggressiveness, tumour invasiveness, and metastasis, particularly in malignant tumours.

Article Synopsis
  • Heat shock proteins (HSPs), particularly HSP70, are linked to tumor growth and immune evasion in various cancers, and this study aimed to assess HSP70 as a potential predictor of malignant transformation in oral epithelial dysplasia.* -
  • The research involved analyzing 60 tissue samples, including different grades of dysplasia and normal tissues, for HSP70 expression through immunohistochemistry and statistical methods.* -
  • Results indicated that HSP70 expression increases with the severity of dysplasia and is significantly higher in established carcinoma, suggesting HSP70 may have prognostic value, although further studies with larger sample sizes are necessary for validation.*

Background: Oral squamous cell carcinoma (OSCC) is the most devastating neoplasm with dramatic increase in morbidity and mortality. The detection and prognostic evaluation of precancerous lesions could aid in early control of cancer. Heat shock protein (HSP) 27 has found to be a biomarker and therapeutic target in different types of cancer.
