The Abbreviated New Drug Application (ANDA) is used for the regulatory submission of generic drugs, which are pharmaceutical equivalents to brand-name drugs and distributed without patent protection. Different countries have their own regulatory requirements for the approval of generic drugs, enforced by authorities such as the CDSCO in India, EDQM in Europe, and USFDA in the United States. This review aims to compare the regulatory processes and requirements for generic drug approval in India, Europe, and the US, highlighting key differences and challenges.

Lignocellulosic biomass is available in abundance as a renewable resource, but the major portion of it is often discarded as waste without utilizing its immense potential as an alternative renewable energy resource. To overcome recalcitrance of lignocellulosic biomass, various pretreatment methods are applied to it, so that the complex and rigid polymeric structure can be broken down into fractions susceptible for enzymatic hydrolysis. Effective and efficient biomass processing is the goal of pretreatment methods, but none of the explored pretreatment methods are versatile enough to fulfil the requirement of biomass processing with greater flexibility in terms of operational cost and desired output efficiency.

A key focus of this article includes the proteases responsible for inducing truncation, the specific sites susceptible to truncation, and the resultant influence of these truncated species on the seeding and aggregation of endogenous α-synuclein. We also shed light on the unique structural attributes of these truncated species, and how these modifications can lead to distinctive forms of synucleinopathies.
