This research paper presents a high-gain DC-DC converter with ultra-step-up voltage gain capability. The proposed converter is synthesized from a two-phase interleaved boost converter (IBC), and its voltage gain is doubled by adopting a voltage lift capacitor. To enhance its voltage gain capability, a floating capacitor-based gain extension cell is adopted subsequently.

Aim: To determine two genetically established parameters such as prevalence of GSTM1 null polymorphism and analysis of Palmar dermatoglypics (PD) in patients with Oral Leukoplakia (OL) and Controls.
Materials And Methods: Group I (cases) 30 patients with established histopathological diagnosis of OL and Group II (controls) 30 patients without any habits of tobacco, alcohol usage and without OL were selected.
Schwannoma or neurilemmoma is a benign, slow-growing nerve sheath tumor arising from Schwann cells of the cranial, peripheral or autonomic nerves. Approximately 25%-40% of schwannomas occur in the head and neck region. Occurrences of intraoral schwannomas are rare with reported prevalence being 1%.
