A stem cell is a particular group of cells that has the extraordinary potential to convert within the body into particular cell types. They are used to regenerate tissues and cells in the body that have been damaged or destroyed by the disease. Stem cells come in three different varieties: adult stem cells, embryonic stem cells and induced pluripotent stem cells (iPSCs). Embryonic stem cells have a high chance of immune rejection and also have ethical dilemmas and iPSCs have genetic instability. Adult stem cells are difficult to analyze and extract for research since they are frequently insufficient in native tissues. However, mesenchymal stem cells (MSC) one of the categories of adult stem cells are stromal cells with a variety of potentials that can differentiate into a wide range of cell types. MSCs can be transplanted into a variety of people without worrying about rejection because they have demonstrated the ability to prevent an adverse reaction from the immune system. These transplants have powerful anti-inflammatory and immunosuppressive effects and greatly enhance the body's inherent healing capacity. While MSCs do not offer treatment for illnesses, the idea behind them is to enable the body to recover sufficiently for a protracted reduction in symptoms. In many cases, this is sufficient to significantly enhance the patient's well-being. Inspite of several advantages some potential long-term concerns connected to MSC therapy are maldifferentiation, immunosuppression and cancerous tumor growth. In this review, we will compare the mesenchymal stem cells with other stem cells with respect to the source of origin, their properties and therapeutic applications, and discuss the MSC's disadvantages. � 2023 Elsevier GmbH

(Elsevier B.V., 2023-07-02T00:00:00) Yadav, Nidhi; Maurya, Brij Mohan; Chettri, Dewan; Pooja; Pulwani, Chirag; Jajula, Mahesh; kanda, Savleen Singh; babu, Harysh Winster Suresh; Elangovan, Ajay; Velusamy, Parthasarathy; Iyer, Mahalaxmi; Vellingiri, Balachandar
Heavy metals (HMs) are metallic substances. They enter biotic and abiotic systems through natural and human activities. These HMs have an impact on the atmosphere, soil, and groundwater, and they also affect all living things, especially humans, when they enter the food chain. Therefore, monitoring and removing HMs from the environment and humans are crucial for maintaining HMs-based toxicity. The detection of HMs from environmental and human samples has been performed by techniques such as atomic adsorption spectrometry (AAS) and inductively coupled plasma mass spectrometry (ICP-MS). With the advancement of AI-based technology, HMs are now detected and removed from the environment and human systems. This review discusses the impact of HMs on the environment and human health, their detection and removal techniques, and the integration of recent advancements in AI-based technology for the detection and removal of HMs from environmental and human samples. � 2023 The Author(s)
Assessment of tRNAThr and tRNAGln Variants and Mitochondrial Functionality in Parkinson�s Disease (PD) Patients of Tamil Nadu Population
(Springer, 2023-10-17T00:00:00) Venkatesan, Dhivya; Iyer, Mahalaxmi; Raj, Neethu; Gopalakrishnan, Abilash Valsala; Narayanasamy, Arul; Kumar, Nachimuthu Senthil; Vellingiri, Balachandar
Parkinson�s disease (PD) is speculated with genetic and environmental factors. At molecular level, the mitochondrial impact is stated to be one of the causative reasons for PD. In this study, we investigated the mitochondrial membrane potential (MMP), reactive oxygen species (ROS) and adenosine triphosphate (ATP) levels along with mitochondrial tRNA alterations among three age categories of PD. By determining the genetic and organellar functionality using molecular techniques, the ROS levels were reported to be high with decreased MMP and ATP in the late-onset age group than in other two age categories. Likewise, the tRNA significancy in tRNAThr and tRNAGln was noticed with C4335T and G15927A mutations in late-onset and early-onset PD groups respectively. Therefore, from the findings, ageing has shown a disruption in tRNA metabolism leading to critical functioning of ATP synthesis and MMP, causing oxidative stress in PD patients. These physiological outcomes show that ageing has a keen role in the divergence of mitochondrial function, thereby proving a correlation with ageing and maintenance of mitochondrial homeostasis in PD. � 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

(Elsevier Masson s.r.l., 2023-02-09T00:00:00) Abdal Dayem, Ahmed; Lee, Soo Bin; Lim, Kyung Min; Kim, Aram; Shin, Hyun Jin; Vellingiri, Balachandar; Kim, Young Bong; Cho, Ssang-Goo
Peptides, short protein fragments, can emulate the functions of their full-length native counterparts. Peptides are considered potent recombinant protein alternatives due to their specificity, high stability, low production cost, and ability to be easily tailored and immobilized. Stem cell proliferation and differentiation processes are orchestrated by an intricate interaction between numerous growth factors and proteins and their target receptors and ligands. Various growth factors, functional proteins, and cellular matrix-derived peptides efficiently enhance stem cell adhesion, proliferation, and directed differentiation. For that, peptides can be immobilized on a culture plate or conjugated to scaffolds, such as hydrogels or synthetic matrices. In this review, we assess the applications of a variety of peptides in stem cell adhesion, culture, organoid assembly, proliferation, and differentiation, describing the shortcomings of recombinant proteins and their full-length counterparts. Furthermore, we discuss the challenges of peptide applications in stem cell culture and materials design, as well as provide a brief outlook on future directions to advance peptide applications in boosting stem cell quality and scalability for clinical applications in tissue regeneration. � 2023 The Authors

(Elsevier Inc., 2023-04-11T00:00:00) Ojha, Rupal; Chand, Kailash; Vellingiri, Balachandar; Prajapati, Vijay Kumar
Visceral Leishmaniasis or Kala-Azar is one of the most severe and deadly neglected tropical disease caused by the Leishmania parasite. A few number of vaccines are going through different phases in clinical trial but failing of these vaccines in successive phase trial or less efficacy, urge to develop highly immunogenic and cost-effective treatment to get rid of deadly VL. This study focuses on the development of more potent vaccine candidate against VL. The recombinant vaccine candidate LeiSp was expressed in Pichia pastoris, followed by purification and characterization. The purified protein was also tested for any post-translation modification, which favors being a potent immunogenic candidate. Further, the expression modulation of different pro-inflammatory and anti-inflammatory cytokines was evaluated in THP1 cell lines. A significant upregulation in the expression of pro-inflammatory cytokines while no significant changes were observed in the expression of anti-inflammatory cytokines. The impact of recombinant vaccine protein candidates in infected conditions were determined. Here, upon treatment with chimeric vaccine protein candidate, we observed a considerable recovery in the expression level of pro-inflammatory cytokines, which were downregulated upon infection alone. In addition to this, we found a significant decrease in the expression of anti-inflammatory cytokines, which were upregulated during infection alone. We further validated our findings in infected hPBMCs and observed similar expression modulation of pro-inflammatory and anti-inflammatory cytokines with and without treatment. Thus, the present study indicates that the chimeric LeiSp protein which was designed using bioinformatics approaches shows a potential inductive efficacy for pro-inflammatory cytokines in Leishmania-infected cells. � 2023 Elsevier Inc.
Concurrent Assessment of Oxidative Stress and MT-ATP6 Gene Profiling to Facilitate Diagnosis of Autism Spectrum Disorder (ASD) in Tamil Nadu Population
(Springer, 2023-03-27T00:00:00) Vellingiri, Balachandar; Venkatesan, Dhivya; Iyer, Mahalaxmi; Mohan, Gomathi; Krishnan, Padmavathi; Sai Krishna, Krothapalli; Sangeetha, R.; Narayanasamy, Arul; Gopalakrishnan, Abilash Valsala; Kumar, Nachimuthu Senthil; Subramaniam, Mohana Devi
Autism spectrum disorder (ASD) is a neurodevelopmental disability that causes social impairment, debilitated verbal or nonverbal conversation, and restricted/repeated behavior. Recent research reveals that mitochondrial dysfunction and oxidative stress might play a pivotal role in ASD condition. The goal of this case�control study was to investigate oxidative stress and related alterations in ASD patients. In addition, the impact of mitochondrial DNA (mtDNA) mutations, particularly MT-ATP6, and its link with oxidative stress in ASD was studied. We found that ASD patient�s plasma had lower superoxide dismutase (SOD) and higher catalase (CAT) activity, resulting in lower SOD/CAT ratio. MT-ATP6 mutation analysis revealed that four variations, 8865 G>A, 8684 C>T, 8697 G>A, and 8836 A>G, have a frequency of more than 10% with missense and synonymous (silent) mutations. It was observed that abnormalities in mitochondrial complexes (I, III, V) are more common in ASD, and it may have resulted in MT-ATP6 changes or vice versa. In conclusion, our findings authenticate that oxidative stress and genetics both have an equal and potential role behind ASD and we recommend to conduct more such concurrent research to understand their unique mechanism for better diagnosis and therapeutic for ASD.

A deeper understanding about the role of uranium toxicity in neurodegeneration
(Academic Press Inc., 2023-06-15T00:00:00) Vellingiri, Balachandar
Natural deposits and human-caused releases of uranium have led to its contamination in the nature. Toxic environmental contaminants such as uranium that harm cerebral processes specifically target the brain. Numerous experimental researches have shown that occupational and environmental uranium exposure can result in a wide range of health issues. According to the recent experimental research, uranium can enter the brain after exposure and cause neurobehavioral problems such as elevated motion related activity, disruption of the sleep-wake cycle, poor memory, and elevated anxiety. However, the exact mechanism behind the factor for neurotoxicity by uranium is still uncertain. This review primarily aims on a brief overview of uranium, its route of exposure to the central nervous system, and the likely mechanism of uranium in neurological diseases including oxidative stress, epigenetic modification, and neuronal inflammation has been described, which could present the probable state-of-the-art status of uranium in neurotoxicity. Finally, we offer some preventative strategies to workers who are exposed to uranium at work. In closing, this study highlights the knowledge of uranium's health dangers and underlying toxicological mechanisms is still in its infancy, and there is still more to learn about many contentious discoveries. � 2023 Elsevier Inc.
Epicardial adipose tissue and cardiac lipotoxicity: A review
(Elsevier Inc., 2023-07-05T00:00:00) Mukherjee, Anirban Goutam; Renu, Kaviyarasi; Gopalakrishnan, Abilash Valsala; Jayaraj, Rama; Dey, Abhijit; Vellingiri, Balachandar; Ganesan, Raja
Epicardial adipose tissue (EAT) has morphological and physiological contiguity with the myocardium and coronary arteries, making it a visceral fat deposit with some unique properties. Under normal circumstances, EAT exhibits biochemical, mechanical, and thermogenic cardioprotective characteristics. Under clinical processes, epicardial fat can directly impact the heart and coronary arteries by secreting proinflammatory cytokines via vasocrine or paracrine mechanisms. It is still not apparent what factors affect this equilibrium. Returning epicardial fat to its physiological purpose may be possible by enhanced local vascularization, weight loss, and focused pharmacological therapies. This review centers on EAT's developing physiological and pathophysiological dimensions and its various and pioneering clinical utilities. � 2023 Elsevier Inc.
Evolving strategies and application of proteins and peptide therapeutics in cancer treatment
(Elsevier Masson s.r.l., 2023-05-05T00:00:00) Mukherjee, Anirban Goutam; Wanjari, Uddesh Ramesh; Gopalakrishnan, Abilash Valsala; Bradu, Pragya; Biswas, Antara; Ganesan, Raja; Renu, Kaviyarasi; Dey, Abhijit; Vellingiri, Balachandar; El Allali, Achraf; Alsamman, Alsamman M.; Zayed, Hatem; George Priya Doss, C.
Several proteins and peptides have therapeutic potential and can be used for cancer therapy. By binding to cell surface receptors and other indicators uniquely linked with or overexpressed on tumors compared to healthy tissue, protein biologics enhance the active targeting of cancer cells, as opposed to the passive targeting of cells by conventional small-molecule chemotherapeutics. This study focuses on peptide medications that exist to slow or stop tumor growth and the spread of cancer, demonstrating the therapeutic potential of peptides in cancer treatment. As an alternative to standard chemotherapy, peptides that selectively kill cancer cells while sparing healthy tissue are developing. A mountain of clinical evidence supports the efficacy of peptide-based cancer vaccines. Since a single treatment technique may not be sufficient to produce favourable results in the fight against cancer, combination therapy is emerging as an effective option to generate synergistic benefits. One example of this new area is the use of anticancer peptides in combination with nonpeptidic cytotoxic drugs or the combination of immunotherapy with conventional therapies like radiation and chemotherapy. This review focuses on the different natural and synthetic peptides obtained and researched. Discoveries, manufacture, and modifications of peptide drugs, as well as their contemporary applications, are summarized in this review. We also discuss the benefits and difficulties of potential advances in therapeutic peptides. � 2023

The human papillomavirus (HPV), commonly documented as the cause of warts, has gained much interest recently due to its possible links to several types of cancer. HPV infection is discussed in this review from multiple angles, including its virology, epidemiology, etiology, immunology, clinical symptoms, and treatment. Recent breakthroughs in molecular biology have led to the development of new methods for detecting and treating HPV in tissue. There is no cure for HPV, and although vaccines are available to prevent infection with the most common HPV viruses, their utilization is limited. Destruction and excision are the primary treatment modalities. This review sheds light on the epidemiology, molecular pathogenesis, the association of several other pathogens with HPV, the latest treatment strategies available to treat the same, and an overview of the progress made and the obstacles still to be overcome in the fight against HPV infection. � 2022 by the authors.
Exploring the Regulatory Role of ncRNA in NAFLD: A Particular Focus on PPARs
(MDPI, 2022-12-08T00:00:00) Mukherjee, Anirban Goutam; Wanjari, Uddesh Ramesh; Gopalakrishnan, Abilash Valsala; Katturajan, Ramkumar; Kannampuzha, Sandra; Murali, Reshma; Namachivayam, Arunraj; Ganesan, Raja; Renu, Kaviyarasi; Dey, Abhijit; Vellingiri, Balachandar; Prince, Sabina Evan
Liver diseases are responsible for global mortality and morbidity and are a significant cause of death worldwide. Consequently, the advancement of new liver disease targets is of great interest. Non-coding RNA (ncRNA), such as microRNA (miRNA) and long ncRNA (lncRNA), has been proven to play a significant role in the pathogenesis of virtually all acute and chronic liver disorders. Recent studies demonstrated the medical applications of miRNA in various phases of hepatic pathology. PPARs play a major role in regulating many signaling pathways involved in various metabolic disorders. Non-alcoholic fatty liver disease (NAFLD) is the most prevalent form of chronic liver disease in the world, encompassing a spectrum spanning from mild steatosis to severe non-alcoholic steatohepatitis (NASH). PPARs were found to be one of the major regulators in the progression of NAFLD. There is no recognized treatment for NAFLD, even though numerous clinical trials are now underway. NAFLD is a major risk factor for developing hepatocellular carcinoma (HCC), and its frequency increases as obesity and diabetes become more prevalent. Reprogramming anti-diabetic and anti-obesity drugs is an effective therapy option for NAFLD and NASH. Several studies have also focused on the role of ncRNAs in the pathophysiology of NAFLD. The regulatory effects of these ncRNAs make them a primary target for treatments and as early biomarkers. In this study, the main focus will be to understand the regulation of PPARs through ncRNAs and their role in NAFLD. � 2022 by the authors.
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.

HPV-associated cancers: insights into the mechanistic scenario and latest updates
(Springer, 2023-06-26T00:00:00) Mukherjee, Anirban Goutam; Ramesh Wanjari, Uddesh; Valsala Gopalakrishnan, Abilash; Jayaraj, Rama; Katturajan, Ramkumar; Kannampuzha, Sandra; Murali, Reshma; Namachivayam, Arunraj; Evan Prince, Sabina; Vellingiri, Balachandar; Dey, Abhijit; Renu, Kaviyarasi
Cancer and related diseases are the second leading cause of death worldwide. The human papillomavirus (HPV) is an infectious agent that can be spread mainly through sexual contact and has been linked to several malignancies in both sexes. HPV is linked to almost all cases of cervical cancer. It is also linked to many head and neck cancer (HNC) cases, especially oropharyngeal cancer. Also, some HPV-related cancers, like vaginal, vulvar, penile, and anal cancers, are related to the anogenital area. Over the past few decades, testing for and preventing cervical cancer has improved, but anogenital cancers are still harder to confirm. HPV16 and HPV18 have been extensively researched due to their significant carcinogenic potential. The products of two early viral genes, E6 and E7, have been identified as playing crucial roles in cellular transformation, as emphasized by biological investigations. The complete characterization of numerous mechanisms employed by E6 and E7 in undermining the regulation of essential cellular processes has significantly contributed to our comprehension of HPV-induced cancer progression. This review focuses on the various types of cancers caused by HPV infection and also sheds light on the signaling cascades involved in the same. � 2023, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.
The Implication of Mechanistic Approaches and the Role of the Microbiome in Polycystic Ovary Syndrome (PCOS): A Review
(MDPI, 2023-01-16T00:00:00) Mukherjee, Anirban Goutam; Wanjari, Uddesh Ramesh; Kannampuzha, Sandra; Murali, Reshma; Namachivayam, Arunraj; Ganesan, Raja; Dey, Abhijit; Babu, Achsha; Renu, Kaviyarasi; Vellingiri, Balachandar; Ramanathan, Gnanasambandan; George Priya Doss, C.; Elsherbiny, Nehal; Elsherbini, Amira M.; Alsamman, Alsamman M.; Zayed, Hatem; Gopalakrishnan, Abilash Valsala
As a complex endocrine and metabolic condition, polycystic ovarian syndrome (PCOS) affects women�s reproductive health. These common symptoms include hirsutism, hyperandrogenism, ovulatory dysfunction, irregular menstruation, and infertility. No one knows what causes it or how to stop it yet. Alterations in gut microbiota composition and disruptions in secondary bile acid production appear to play a causative role in developing PCOS. PCOS pathophysiology and phenotypes are tightly related to both enteric and vaginal bacteria. Patients with PCOS exhibit changed microbiome compositions and decreased microbial diversity. Intestinal microorganisms also alter PCOS patient phenotypes by upregulating or downregulating hormone release, gut-brain mediators, and metabolite synthesis. The human body�s gut microbiota, also known as the �second genome,� can interact with the environment to improve metabolic and immunological function. Inflammation is connected to PCOS and may be caused by dysbiosis in the gut microbiome. This review sheds light on the recently discovered connections between gut microbiota and insulin resistance (IR) and the potential mechanisms of PCOS. This study also describes metabolomic studies to obtain a clear view of PCOS and ways to tackle it. � 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.

Insights into the Scenario of SARS-CoV-2 Infection in Male Reproductive Toxicity
(MDPI, 2023-02-23T00:00:00) Mukherjee, Anirban Goutam; Wanjari, Uddesh Ramesh; Gopalakrishnan, Abilash Valsala; Kannampuzha, Sandra; Murali, Reshma; Namachivayam, Arunraj; Ganesan, Raja; Renu, Kaviyarasi; Dey, Abhijit; Vellingiri, Balachandar; Prabakaran, D.S.
COVID-19 has become a significant public health concern that has catastrophic consequences for society. Some preliminary evidence suggests that the male reproductive system may be an infection target for SARS-CoV-2. SARS-CoV-2 may be transmitted sexually, according to preliminary research. Testicular cells exhibit a high level of the angiotensin-converting enzyme 2 (ACE2) receptor, which enhances the entry of the SARS-CoV-2 into host cells. Some instances of COVID-19 have been documented to exhibit hypogonadism during the acute stage. Furthermore, systemic inflammatory reactions triggered by SARS-CoV-2 infection may cause oxidative stress (OS), which has been shown to have profoundly deleterious consequences on testicular functioning. This work gives a clear picture of how COVID-19 may affect male reproductive systems and calls attention to the many unanswered questions about the mechanisms by which this virus can be linked to men�s health and fertility. � 2023 by the authors.
miRNA in Parkinson's disease:�From pathogenesis to theranostic approaches
(John Wiley and Sons Inc, 2022-12-11T00:00:00) Elangovan, Ajay; Venkatesan, Dhivya; Selvaraj, Priyanka; Pasha, Md. Younus; Babu, Harysh Winster Suresh; Iyer, Mahalaxmi; Narayanasamy, Arul; Subramaniam, Mohana Devi; Valsala Gopalakrishnan, Abilash; Kumar, Nachimuthu Senthil; Vellingiri, Balachandar
Parkinson's disease (PD) is an age associated neurological disorder which is specified by cardinal motor symptoms such as tremor, stiffness, bradykinesia, postural instability, and non-motor symptoms. Dopaminergic neurons degradation in substantia nigra region and aggregation of ?Syn are the classic signs of molecular defects noticed in PD pathogenesis. The discovery of microRNAs (miRNA) predicted to have a pivotal part in various processes regarding regularizing the cellular functions. Studies on dysregulation of miRNA in PD pathogenesis has recently gained the concern where our review unravels the role of miRNA expression in PD and its necessity in clinical validation for therapeutic development in PD. Here, we discussed how miRNA associated with ageing process in PD through molecular mechanistic approach of miRNAs on sirtuins, tumor necrosis factor-alpha and interleukin-6, dopamine loss, oxidative stress and autophagic dysregulation. Further we have also conferred the expression of miRNAs affected by SNCA gene expression, neuronal differentiation and its therapeutic potential with PD. In conclusion, we suggest more rigorous studies should be conducted on understanding the mechanisms and functions of miRNA in PD which will eventually lead to discovery of novel and promising therapeutics for PD. � 2022 Wiley Periodicals LLC.
Molecular mechanisms of alcohol's effects on the human body: A review and update

Alcohol consumption has been linked to numerous negative health outcomes although it has some beneficial effects on moderate dosages, the most severe of which being alcohol-induced hepatitis. The number of people dying from this liver illness has been shown to climb steadily over time, and its prevalence has been increasing. Researchers have found that alcohol consumption primarily affects the brain, leading to a wide range of neurological and psychological diseases. High-alcohol-consumption addicts not only experienced seizures, but also ataxia, aggression, social anxiety, and variceal hemorrhage that ultimately resulted in death, ascites, and schizophrenia. Drugs treating this liver condition are limited and can cause serious side effects like depression. Serine-threonine kinases, cAMP protein kinases, protein kinase C, ERK, RACK 1, Homer 2, and more have all been observed to have their signaling pathways disrupted by alcohol, and alcohol has also been linked to epigenetic changes. In addition, alcohol consumption induces dysbiosis by changing the composition of the microbiome found in the gastrointestinal tract. Although more studies are needed, those that have been done suggest that probiotics aid in keeping the various microbiota concentrations stable. It has been argued that reducing one's alcohol intake may seem less harmful because excessive drinking is a lifestyle disorder. � 2023 Wiley Periodicals LLC.
Nano-biotechnology in tumour and cancerous disease: A�perspective review
(John Wiley and Sons Inc, 2023-02-25T00:00:00) Soni, Ambikesh; Bhandari, Manohar Prasad; Tripathi, Gagan Kant; Bundela, Priyavand; Khiriya, Pradeep Kumar; Khare, Purnima Swarup; Kashyap, Manoj Kumar; Dey, Abhijit; Vellingiri, Balachandar; Sundaramurthy, Suresh; Suresh, Arisutha; P�rez�de�la�Lastra, Jos� M.
In recent years, drug manufacturers and researchers have begun to consider the nanobiotechnology approach to improve the drug delivery system for tumour and cancer diseases. In this article, we review current strategies to improve tumour and cancer drug delivery, which mainly focuses on sustaining biocompatibility, biodistribution, and active targeting. The conventional therapy using cornerstone drugs such as fludarabine, cisplatin etoposide, and paclitaxel has its own challenges especially not being able to discriminate between tumour versus normal cells which eventually led to toxicity and side effects in the patients. In contrast to the conventional approach, nanoparticle-based drug delivery provides target-specific delivery and controlled release of the drug, which provides a better therapeutic window for treatment options by focusing on the eradication of diseased cells via active targeting and sparing normal cells via passive targeting. Additionally, treatment of tumours associated with the brain is hampered by the impermeability of the blood�brain barriers to the drugs, which eventually led to poor survival in the patients. Nanoparticle-based therapy offers superior delivery of drugs to the target by breaching the blood�brain barriers. Herein, we provide an overview of the properties of nanoparticles that are crucial for nanotechnology applications. We address the potential future applications of nanobiotechnology targeting specific or desired areas. In particular, the use of nanomaterials, biostructures, and drug delivery methods for the targeted treatment of tumours and cancer are explored. � 2023 The Authors.
