Graphene-infused terracotta acoustic sound amplifiers.

This work introduces a novel approach for enhancing mobile audio performance by incorporating graphene-infused terracotta as an acoustic amplifier. Leveraging the high thermal conductivity and mechanical strength of graphene, this study demonstrates the design, fabrication, and acoustic characterization of terracotta amplifiers. We demonstrate the significant impact of graphene-infused terracotta amplifiers on improving sound amplification in addition to mechanical strength.

Adhesion-related proteins E-cadherin, P-cadherin, CD44, and CD44v6, and antimetastatic protein nm23H1 in complete hydatidiform moles in relation to invasion potential.

Cell adhesion has an essential role in regulating metastasis, and loss of cell adhesion is a classic feature of invasion. There is currently a great deal of interest in the role of adhesion proteins and the antimetastatic protein nm23H1 in the progression of cancer. However, reports on the expression of these proteins in complete hydatidiform moles (CHMs) are limited.

Increased expression of interleukin-1 beta is associated with persistence of the disease and invasion in complete hydatidiform moles (CHM).

Complete hydatidiform moles (CHM), a post-conceptual pathologic condition of the placenta, have a high prevalence rate (12/1,000 deliveries) in Kerala, India. This study addresses the expression of IL-1 alpha and beta by immunohistochemistry in relation to persistence and invasion of the disease. Mild to moderate expression of IL-1 alpha in the villous cytotrophoblasts, syncytiotrophoblasts and decidua of the first trimester in the normal placenta and all gestational ages in the molar placenta were observed.

Lectin binding as a prognostic indicator in gestational trophoblastic diseases (GTD).

Gestational Trophoblastic Diseases (GTD) is a group of hyperproliferative conditions of the placenta. Very often these can be fatal or recurrent. Presently, no reliable marker is available apart from serum beta HCG levels to identify tumours with a higher aggressive nature, the reduction pattern of the serum beta HCG levels indicating persistence of the disease.

The presence of human papillomavirus-16/-18 E6, p53, and Bcl-2 protein in cervicovaginal smears from patients with invasive cervical cancer.

Cervical cancer is the second leading cause of death from cancer in women worldwide, and recent epidemiological studies have strongly implicated the sexually transmitted human papillomavirus (HPV) as a causative agent. The ability of high-risk HPVs to contribute to malignant progression seems to depend on expression of the viral E6 and E7 oncogenes. The E6 oncoprotein forms a complex with the cellular tumor suppressor protein p53, leading to degradation of p53 via ubiquitin-dependent proteolysis.
