Heavy Metal and Metalloid Contamination in Food and Emerging Technologies for Its Detection
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-01-09T00:00:00) Mukherjee, Anirban Goutam; Renu, Kaviyarasi; Gopalakrishnan, Abilash Valsala; Veeraraghavan, Vishnu Priya; Vinayagam, Sathishkumar; Paz-Montelongo, Soraya; Dey, Abhijit; Vellingiri, Balachandar; George, Alex; Madhyastha, Harishkumar; Ganesan, Raja
Heavy metal and metalloid poisoning in the environment and food has piqued the public�s interest since it poses significant hazards to the ecological system and human health. In food, several metals, including cadmium (Cd), lead (Pb), mercury (Hg), tin (Sn), manganese (Mn), and aluminium (Al), and metalloids, including arsenic (As), antimony (Sb), and selenium (Se), pose a severe threat to human health. It is of utmost importance to detect even minute quantities of these toxic elements and this must be efficiently determined to understand their risk. Several traditional and advanced technologies, including atomic absorption spectrometry (AAS), spectrofluorimetry, inductively coupled plasma spectrometry, e-tongues, electrochemical aptasensors, Raman spectroscopy, and fluorescence sensors, among other techniques, have proven highly beneficial in quantifying even the minute concentrations of heavy metals and metalloids in food and dietary supplements. Hence, this review aims to understand the toxicity of these metals and metalloids in food and to shed light on the emerging technologies for their detection. � 2023 by the authors.

Implications of cancer stem cells in diabetes and pancreatic cancer
(Elsevier Inc., 2022-11-19T00:00:00) Mukherjee, Anirban Goutam; Wanjari, Uddesh Ramesh; Gopalakrishnan, Abilash Valsala; Bradu, Pragya; Sukumar, Aarthi; Patil, Megha; Renu, Kaviyarasi; Dey, Abhijit; Vellingiri, Balachandar; George, Alex; Ganesan, Raja
This review provides a detailed study of pancreatic cancer (PC) and the implication of different types of cancers concerning diabetes. The combination of anti-diabetic drugs with other anti-cancer drugs and phytochemicals can help prevent and treat this disease. PC cancer stem cells (CSCs) and how they migrate and develop into malignant tumors are discussed. A detailed explanation of the different mechanisms of diabetes development, which can enhance the pancreatic CSCs' proliferation by increasing the IGF factor levels, epigenetic modifications, DNA damage, and the influence of lifestyle factors like obesity, and inflammation, has been discussed. It also explains how cancer due to diabetes is associated with high mortality rates. One of the well-known diabetic drugs, metformin, can be combined with other anti-cancer drugs and prevent the development of PC and has been taken as one of the prime focus in this review. Overall, this paper provides insight into the relationship between diabetes and PC and the methods that can be employed to diagnose this disease at an earlier stage successfully. � 2022 Elsevier Inc.
Onco-Pathogen Mediated Cancer Progression and Associated Signaling Pathways in Cancer Development
(MDPI, 2023-05-28T00:00:00) Kannampuzha, Sandra; Gopalakrishnan, Abilash Valsala; Padinharayil, Hafiza; Alappat, Reema Rose; Anilkumar, Kavya V.; George, Alex; Dey, Abhijit; Vellingiri, Balachandar; Madhyastha, Harishkumar; Ganesan, Raja; Ramesh, Thiyagarajan; Jayaraj, Rama; Prabakaran, D.S.
Infection with viruses, bacteria, and parasites are thought to be the underlying cause of about 8�17% of the world�s cancer burden, i.e., approximately one in every five malignancies globally is caused by an infectious pathogen. Oncogenesis is thought to be aided by eleven major pathogens. It is crucial to identify microorganisms that potentially act as human carcinogens and to understand how exposure to such pathogens occur as well as the following carcinogenic pathways they induce. Gaining knowledge in this field will give important suggestions for effective pathogen-driven cancer care, control, and, ultimately, prevention. This review will mainly focus on the major onco-pathogens and the types of cancer caused by them. It will also discuss the major pathways which, when altered, lead to the progression of these cancers. � 2023 by the authors.
