Exploring the Role of Small Dense LDL-C and Paraoxonase-I Activity in Lipid Profile Alterations in Postmenopausal Women: Evidence from a Population-Based Study in Punjab, India
Abstract: Background: After menopause, women face a higher risk of cardiovascular disease (CVD) because hormonal changes impact how their bodies process fats. This study aimed to explore the relationship between small dense LDL cholesterol (sdLDL-C), lipid profile, PON1 levels, thyroid function, CBC parameters, and cardiovascular risk in postmenopausal women (45–60 years) in Punjab, India. sdLDL-C is more atherogenic than larger LDL particles, while PON1, linked to HDL, offers heart protection. Thyroid …

The Anhadnaad Universe
Abstract: Current Science considers that 95% universe is made of Dark energy and Dark Matter which are completely unknown entities and can’t be detected directly. Current Science also does not believe in independent existence of Consciousness on its own. It rather consider it as an outcome of electrical interaction in brain cells which means there are as many consciousnesses as the number of brains in the entire universe. But my theory …
