Background: Indian Diabetes Risk Score (IDRS) is a screening tool for quantifying the risk of diabetes mellitus (DM) development in the Indian population. The present study has evaluated the level of risk of developing DM in Chandigarh and Panchkula based on the IDRS score. Methods: As a part of a national diabetes control trial funded by the Ministry of Health and Family Welfare (MoHFW) and the Ministry of AYUSH, Government of India, 1,916 participants from the Chandigarh and Panchkula regions were assessed for the risk of developing DM. Risk assessment was done on the basis of the IDRS score which includes age, family history, waist circumference, and physical activity as its contributing factors. Participants with an IDRS score 60 were in the high-risk category for DM. Results: Out of the 1,916 screened respondents (59.86% females and 40.14% males), 894 participants (46.65%) were at a high risk for DM (IDRS >60), 764 (39.87%) were at a moderate risk (IDRS = 30–60), and 258 (13.46%) were at a low risk (IDRS Conclusion: The Chandigarh and Panchkula population showed a high tendency to develop DM based on the IDRS score. Modifiable risk factors such as waist circumference and physical activity were the major contributing factors. Apart from the modifiable risk factors, age was also another major contributing risk factor. Based on these outcomes, lifestyle modifications like yoga and exercise can be proposed for this population as a preventive approach to reduce the risk of developing DM and other associated cerebrovascular complications.

Age-related macular degeneration (AMD) is a devastating retinal disease that results in irreversible vision loss in the aged population. The complex genetic nature and degree of genetic penetrance require a redefinition of the current therapeutic strategy for AMD. We aimed to investigate the role of modifiers for current anti-VEGF therapy especially for non-responder AMD patients. We recruited 78 wet AMD cases (out of 278 AMD patients) with their socio-demographic and treatment regimen. Serum protein levels were estimated by ELISA in AMD patients. Data pertaining to the number of anti-VEGF injections given (in 1 year) along with clinical images (FFA and OCT) of AMD patients were also included. Visual acuity data (logMAR) for 46 wet AMD cases out of a total of 78 patients were also retrieved to examine the response of anti-VEGF injections in wet AMD cases. Lipid metabolizing genes (LIPC and APOE) have been identified as chief biomarkers for anti-VEGF response in AMD patients. Both genotypes ‘CC’ and ‘GC’ of LIPC have found to be associated with a number of anti-VEGF injections in AMD patients which could influence the expression of B3GALTL,HTRA1, IER3, LIPC and SLC16A8 proteins in patients bearing both genotypes as compared to reference genotype. Elevated levels of APOE were also observed in group 2 wet AMD patients as compared to group 1 suggesting the significance of APOE levels in anti-VEGF response. The genotype of B3GALTL has also been shown to have a significant association with the number of anti-VEGF injections. Moreover, visual acuity of group 1 (≤ 4 anti-VEGF injections/year) AMD patients was found significantly improved after 3 doses of anti-VEGF injections and maintained longitudinally as compared to groups 2 and 3. Lipid metabolising genes may impact the outcome of anti-VEGF AMD treatment.

Background: Cancer is a common disease caused by the excessive proliferation of cells, and neurodegenerative diseases are the disorders caused due to the degeneration of neurons. Both can be considered as diseases caused by the dysregulation of cell cycle events. A recent data suggests that there is a strong inverse association between cancer and neurodegenerative disorders. There is indirect evidence to postulate Brain-derived Neurotrophic Factor (BDNF) as a potential molecular link in this association. Discussion: The BDNF levels are found to be downregulated in many neurodegenerative disorders and are found to be upregulated in various kinds of cancers. The lower level of BDNF in Alzheimer’s and Parkinson’s disease has been found to be related to cognitive and other neuropsychological impairments, whereas, its higher levels are associated with the tumour growth and metastasis and poor survival rate in the cancer patients. Conclusion: In this review, we propose that variance in BDNF levels is critical in determining the course of cellular pathophysiology and the development of cancer or neurodegenerative disorder. We further propose that an alternative therapeutic strategy that can modulate BDNF expression, can rescue or prevent above said pathophysiological course. Larger studies that examine this link through animal studies are imperative to understand the putative biochemical and molecular link to wellness and disease.

Background: Many factors including genetic and environmental are responsible for the incidence of Age-related Macular Degeneration (AMD). However, its pathogenesis has not been clearly elucidated yet. Objective: This study aimed to estimate the Age-Related Maculopathy Susceptibility 2 (ARMS2), Collagen type VIII Alpha 1 chain (COL8A1), Rad 51 paralog(RAD51B), and Vascular Endothelial Growth Factor (VEGF) protein levels in serum of AMD and control participants and to further investigate their correlation to understand AMD pathogenesis. Methods: For this case-control study, 31 healthy control and 57 AMD patients were recruited from Advanced Eye Centre, Post Graduate Institute of Medical Education and Research, Chandigarh, India. A blood sample was taken and serum was isolated from it. ELISA (enzyme-linked immunosorbent assay) was used for the estimation of proteins in the serum of patients. Results: ARMS2 and COL8A1 levels were significantly elevated in the AMD group than in the control group. The highest levels of ARMS2, COL8A1, and VEGF proteins were recorded for the wet AMD sub-group. The study results endorsed significant positive correlation between these following molecules; ARMS2 and COL8A1 (r = 0.933, p < 0.0001), ARMS2 and RAD51B (r = 0.704, p < 0.0001), ARMS2 and VEGF (r = 0.925, p < 0.0001), COL8A1 and RAD51B (r = 0.736, p < 0.0001), COL8A1 and VEGF (r = 0.879, p < 0.0001), and RAD51B and VEGF (r = 0.691, p < 0.0001). Conclusion: The ARMS2 and COL8A1 levels were significantly higher and RAD51B was significantly lower in the AMD group than controls. Also, a significant statistical correlation was detected between these molecules, indicating that their interaction may be involved in the pathogenesis of AMD.

Quality assurance (QA) is an indispensable part of manufacturing industries and corporate. Academics also require QA to avoid misconduct and conflicts. Adhering to Good Lab Practices (GLP) is definitely a prerequisite for quality research. Implementation of QA should be done at different stages of research like the inception of research idea, generation of data, and presentation of research data to avoid any future conflicts. There are numerous examples in the history of research and academics where considerable conflicts raised doubts about the credibility and quality of research. QA provides the reproducibility, back traceability, and reliability of the generated data. It not only strengthens and encourages the researchers to contribute in the respective field but also acts as a defensive shield against jealousy and negative competition-driven accusations. Protection of intellectual property is also vital in academics as it is a sensitive area often infested with conflicts. QA can help in this regard by safeguarding Intellectual Property. Stringent implementation and monitoring of the QA and timely amendment can provide the maximum benefits in academics and research fraternities. This chapter describes the concepts like implementation of QA in academics, history of scientific misconduct which supports the notion of the need for QA, and also lays a format for how QA can be implemented at various stages of research. Here we also discuss the role of QA personnel in ensuring Quality in a GLP laboratory. It basically outlines the importance of QA and how it can be implemented in academics to avoid conflicts and improve the quality standard of research.

The analysis of degenerative diseases has revealed genetic heterogeneity and this appears to contribute towards an increase in the complexity of disease with influences from environmental factors. Worldwide Genetic studies have identified various common and non-synonymous alleles with AMD across the geographically distributed population. With the advancement in technology, the biological contribution of rare alleles and “Junk DNA” in AMD has been suggested. The biological significance of intronic, rare alleles, and transposons in degenerative diseases can provide the necessary information to assess the evolution of the complexity of AMD pathology.

Background: The deprivation of oxygen reaching the tissues (also termed as hypoxia) affects the normal functioning of the body. This results in development of many diseases like ischemia, glaucoma, MCI (Mild Cognitive Impairment), pulmonary and cerebral edema, stress and depression. There are no effective drugs that can treat such diseases. Despite such failure, alternative interventions such as mind-body techniques (MBTs) have not been adequately investigated. Methods: The first part of this review has been focused on philosophical aspects of various MBTs besides evolving an ayurgenomic perspective. The potential of MBTs as a preventive non-pharmacological intervention in the treatment of various general and hypoxic pathologies has been further described in this section. In the second part, molecular, physiological, and neuroprotective roles of MBTs in normal and hypoxic/ischemic conditions has been discussed. Results: In this respect, the importance of and in vivo studies has also been discussed. Conclusions: Although several studies have investigated the role of protective strategies in coping with the hypoxic environment, the efficacy of MBTs at the molecular level has been ignored.

Aims To screen the Indian population for Type 2 Diabetes Mellitus (DM) based on Indian Diabetes Risk Score. Our main question was; Does Indian Diabetic risk score (IDRS) effectively screen diabetic subjects in Indian population? Methods Multi-centric nationwide screening for DM and its risk in all populous states and Union territories of India in 2017. It is the first pan India DM screening study conducted on 240,000 subjects in a short period of 3 months based on IDRS. This was a stratified translational research study in randomly selected cluster populations from all zones of rural and urban India. Two non-modifiable (age, family history) and two modifiable (waist circumference & physical activity) were used to obtain the score. High, moderate and low risk groups were selected based on scores. Results In this study 40.9% subjects were detected to be high risk, known or newly diagnosed DM subjects in urban and rural regions. IDRS could detect 78.1% known diabetic subjects as high risk group. Age group 50–59 (17.4%); 60–69 (22%); 70–79 (22.8%); >80 (19.2%) revealed high percentage of subjects. ROC was found to be 0.763 at CI 95% of 0.761–0.765 with statistical significance of p 50 cut off, youden index showed the sensitivity of 78.05 and specificity of 62.68. Regression analysis revealed that IDRS and Diabetes are significantly positively associated. Conclusions Data reveals that IDRS is a good indicator of high risk diabetic subjects.

Aim Isoniazid (INH), Rifampicin (RIF) and Pyrazinamide (PZA) are part of first-line anti-tuberculosis therapy used against infection caused by Mycobacterium tuberculosis. However, these drugs are known to be potentially harmful as these are associated with numerous side effects and when taken together their harmful outcomes are elevated in a synergistic manner. Identification of possible mechanism underlying RIF + INH + PZA induced nephrotoxicity may be advantageous in developing strategies to prevent their toxic implications. Methods In this study rats were distributed in two groups of six each: Control (tap water) and Toxicant (INH + RIF + PZA) in dosage derived through extrapolation from human dosage for 28 days once in a day. Antioxidant activity and histology of kidney were examined. In addition, apoptosis was also studied using pro and anti-apoptotic markers and TUNEL staining to check nephrotoxicity. Results Findings indicated that combined (INH, RIF and PZA) 28 day exposure in Wistar rats caused increase in number of free radicals/ reactive oxygen species which further cause changes in levels of enzymatic antioxidants such as glutathione, Superoxide dismutase, Catalase, and Glutathione-s-transferase. Altered content of pro (BAD&BAX) and anti-apoptotic genes (BCL-2&BCL2L1) genes, TUNEL positive cells and DNA fragmentation emphasized involvement of apoptosis. Conclusion This study concluded that nephrotoxicity is accompanied during combinational anti-tuberculosis drug therapy.
