Shining a Spotlight on Stigma: Exploring Its Impact on Oral Health-Seeking Behaviours Through the Lenses of Patients and Caregivers.

Introduction The unique nature of a lack of good oral health, coupled with the lack of discussion and recognition surrounding the associated stigma, highlights it as a distinct issue. This stigma causes discomfort, devalues individuals, and necessitates urgent care and intervention. In Pakistan, a variety of reasons, including cultural beliefs, socioeconomic gaps, and poor access to dental care services, tend to exacerbate the stigma that is associated with dental care.

Polaron Formation in Conducting Polymers: A Novel Approach to Designing Materials with a Larger NLO Response.

Substantial efforts have been made to design and investigate new approaches for high-performance nonlinear optical (NLO) materials. Herein, we report polaron formation in conducting polymers as a new approach to designing materials with a large NLO response. A comparative study of polypyrrole and polypyrrole-based polaron (nPy where n = 1, 3, 5, 7, and 9) is carried out for optoelectronic and NLO properties.

Polaronic state of conducting oligomer as a new approach to design non-lieaner optical materials: A case study of oligofurans.

The geometric, electronic and nonlinear optical properties of neutral and polaron based oligofurans are studied comparatively. We have reported the role of polaron to trigger the nonlinear optical response of oligofurans (nFu). The polaron based oligomers show excellent opto-electronic properties.

Design, synthesis, antiproliferative activity, estrogen receptors binding affinity of C-3 pregnenolone-dihydropyrimidine derivatives for the treatment of breast cancer.

Breast cancer (BCa) is very common malignancy and globally, has become the second leading cause of cancer death among women. For the treatment of BCa, estrogen receptors-alpha (ERα) has proven to be a therapeutic target. In continuation of our previous reported dihydropyrimidine-based pregnenolone derivatives, we modified at C-3 hydroxyl group.

Rational design, synthesis, antiproliferative activity against MCF-7, MDA-MB-231 cells, estrogen receptors binding affinity, and computational study of indenopyrimidine-2,5-dione analogs for the treatment of breast cancer.

Based on the structural architecture of estrogen receptors (ER) agonists/antagonists, we rationally designed and synthesized indenopyrimidine-2,5-dione analogs as a starting point of current research targeting estrogen receptors. These analogs were evaluated for their antiproliferative activities against breast cancer MCF-7 (ER), MDA-MB-231 (ER) and non-cancerous HEK-293 cells using MTT assay. Compounds with high antiproliferative activity against MCF-7 breast cancer cells were found devoid of cytotoxicity against HEK-293 cells.

WNT signalling pathway in oral lesions.

Wingless-Integrated/Beta-catenin (WNT/-catenin) signalling pathway is one of the principal intercellular signalling pathways in humans. It plays an intrinsic role in the cellular proliferation, differentiation and regeneration along with many other cellular functions. Epigenetic deoxyribonucleic acid methylations and silencing of WNT signalling pathway genes have a significant role in malignant transformation of oral lesions such as oral submucous fibrosis, oral leukoplakia, oral lichen planus and erythroplakia.
