    Converged avenues: depression and Alzheimer’s disease– shared pathophysiology and novel therapeutics
    (Springer, 2024-01) Mahesh, Radhakrishnan
    Depression, a highly prevalent disorder affecting over 280 million people worldwide, is comorbid with many neurological disorders, particularly Alzheimer’s disease (AD). Depression and AD share overlapping pathophysiology, and the search for accountable biological substrates made it an essential and intriguing field of research. The paper outlines the neurobiological pathways coinciding with depression and AD, including neurotrophin signalling, the hypothalamic–pituitary–adrenal axis (HPA), cellular apoptosis, neuroinflammation, and other aetiological factors. Understanding overlapping pathways is crucial in identifying common pathophysiological substrates that can be targeted for effective management of disease state. Antidepressants, particularly monoaminergic drugs (first-line therapy), are shown to have modest or no clinical benefits. Regardless of the ineffectiveness of conventional antidepressants, these drugs remain the mainstay for treating depressive symptoms in AD. To overcome the ineffectiveness of traditional pharmacological agents in treating comorbid conditions, a novel therapeutic class has been discussed in the paper. This includes neurotransmitter modulators, glutamatergic system modulators, mitochondrial modulators, antioxidant agents, HPA axis targeted therapy, inflammatory system targeted therapy, neurogenesis targeted therapy, repurposed anti-diabetic agents, and others. The primary clinical challenge is the development of therapeutic agents and the effective diagnosis of the comorbid condition for which no specific diagnosable scale is present. Hence, introducing Artificial Intelligence (AI) into the healthcare system is revolutionary. AI implemented with interdisciplinary strategies (neuroimaging, EEG, molecular biomarkers) bound to have accurate clinical interpretation of symptoms. Moreover, AI has the potential to forecast neurodegenerative and psychiatric illness much in advance before visible/observable clinical symptoms get precipitated.

    Resorption potential of endoflas powder with curcumin gel against endoflas for pulpectomy in primary mandibular molars: a one-year follow-up evidence-based case reports
    (Springer Nature, 2024-06) Mahesh, Radhakrishnan
    Pediatric endodontics in the primary teeth is chemomechanical due to the difficulties encountered in cleaning and shaping the root canals having complex anatomical configurations. Not only are obturating materials having ideal properties to be used in the primary teeth, but also imparting an impervious hermetic seal to prevent the nidus of reinfection is highly pivotal for the success of pulpectomy. However, certain obturating materials contain one or the other components that are irritant to the periapical region and aggravates the inflammatory process. Hence, a paradigm shift has been witnessed with the evolution of herbal medicines having innumerable beneficial properties with a broad-spectrum action to replace those components causing irritation and inflammatory reactions in conventional obturating materials. One such herbal medicament is “curcumin” popularly known as the “golden herb,” which has a wide repertoire of medicinal properties due to its bioactive component and volatile oil “turmerone.” Endoflas is one of the suitable obturating agents used in the primary teeth for its high success rate, but the use of eugenol in it is associated with irritation of the periapical region and causes necrosis of bone and cementum. Hence, the present case report aims to assess the rate of resorption, resorption potential, and the periapical healing of a novel obturating material Endoflas powder with curcumin gel (EPCG) replacing the liquid eugenol against conventional Endoflas material for pulpectomy in primary mandibular molars.
