• Organic acids are acid in nature. • Dietary organic acids have no risk factors. • Organic acids have antimicrobial activity. • They attenuate Alzheimer disease via antioxidant activity to affect the amyloid aggregation pathway. Organic acids are specific groups of chemicals that contain COOH in their structures. They have properties of weakly acidic nature and dissolves completely into protons when present in aqueous solutions. In biological systems, organic acids are involved in various activities such as important intermediates in various metabolic cycles, antimicrobial compounds, and prediction of maturity indices. Due to these properties, organic acids are important phytochemicals that have a wide range of commercial applications like animal feeds utilization, improve plant quality, bactericidal and bacteriostatic potential, as well as in the pharmaceutical industry for numerous preparations. In pharmacokinetics, organic acids are primarily involved in the absorption of pH-dependent drugs. Different techniques have been employed for the extraction, purification, and quantification of organic acids. Among them, microwave-assisted extractions (MAE) and ultrasound-assisted extractions (UAE) are the chiefly used techniques where MAE is one of the most valuable methods for isolating different compounds from plant materials for industrial and analytical purposes. Moreover, bioactive chemicals such as natural organic acid from plants and other sources are important and referred as "lifespan essential"since they havea beneficial effect on healthy aging and Alzheimer's disease (AD). Therefore, dietary organic acids and avoiding risk factors, will reduce the risk of neurodegenerative diseases such as AD and increase a healthy lifespan. Thus, the present study aimed to understand the phytochemistry, biological activities, industrial applications, possible interaction with other drugs/foods supplements,techniques of extraction, purification and fractionation, techniques of identification and quantification, the effect of food processing,and molecular mechanisms of organic acid to attenuate AD.

Diabetes mellitus (DM) is a chronic metabolic disorder in which blood glucose level raises that can result in severe complications. However, the incidence increased mostly by obesity, pregnancy, persistent corpus luteum, and diestrus phase in humans and animals. This review has focused on addressing the possible understanding and pathogenesis of spontaneous DM in canine, feline, and few wild animals. Furthermore, pancreatic associated disorders, diabetic ketoacidosis, hormonal and drug interaction with diabetes, and herbal remedies associated with DM are elucidated. Bibliographic search for the present review was done using PubMed, Scopus, and Google Scholar for articles on concurrent DM in small and wild animals. Persistent corpus luteal and pseudopregnancy in female dogs generate gestational DM (GDM). GDM can also be caused by extensive use of drugs/hormones such as glucocorticosteroids. Although many similarities are present between diabetic cats and diabetic humans which present islet amyloidosis, there was a progressive loss of β- and α-cells and the normal number of δ-cells. The most prominent similarity is the occurrence of islet amyloidosis in all cases of diabetic cat and over 90% of human non-insulin dependent DM Type-2. Acute pancreatic necrosis (APN) occurs due to predisposing factors such as insulin antagonism, insulin resistance, alteration in glucose tolerance, obesity, hyperadrenocorticism, and persistent usage of glucocorticoids, as these play a vital role in the progression of APN. To manage such conditions, it is important to deal with the etiological agent, risk factors, diagnosis of diabetes, and hormonal and drug interaction along with its termination with suitable therapy (herbal) protocols. It should be noted that the protocols used for the diagnosis and treatment of human DM are not appropriate for animals. Further investigations regarding diabetic conditions of pets and wild animals are required, which will benefit the health status of all animals health worldwide. [ABSTRACT FROM AUTHOR]
