    Association of cytokines levels with epidermal growth factor receptor mutation in lung cancer patients
    (Wolters Kluwer India Pvt. Ltd., 2020-09) Gaur, Priyanka; Bhattacharya, Sandeep; Kant, Surya; Kushwaha, R A. S.; Singh, Gaurav; Pandey, Sarika
    Background: Lung cancer is one of the most frequent types of cancer and the leading cause of cancer-related deaths. Epidermal growth factor receptor (EGFR) is a receptor tyrosine kinase (TK) being highly expressed in lung cancers. Activation of EGFR through oncogenic mutations leads to upregulation of gene expression that may heighten the inflammatory response in certain situations. EGFR acts as a key regulator and a cellular hub for inflammatory cytokine signaling, thereby promoting tumor cell proliferation, invasion, migration, metastases, and survival. The aim of the present study is to determine the serum cytokines levels and EGFR mutation status in lung cancer patients to investigate the association between the EGFR mutation status and cytokines levels with lung cancer patients. Materials and Methods: Blood and tissue samples of lung cancer patients were collected. The EGFR mutations of lung cancer patients were determined by the immunohistochemistry (IHC) and serum cytokines levels of lung cancer patients were determined using ELISA. Results: Statistically significant association of EGFR mutations with adenocarcinoma subtypes and non-smokers were found (P < 0.05). Lung cancer patients with EGFR mutations had significantly higher tumor necrosis factor-alpha levels when compared to lung cancer patients without EGFR mutations (P < 0.01), and EGFR mutation status was not significantly associated with interleukin-6 levels (P = 0.24). Conclusion: EGFR mutation detection by the IHC method is a potentially useful tool to guide clinicians for personalized treatment of lung cancer patients of adenocarcinoma subtype, and cytokines are good biomarkers for the diagnosis, prognosis, and prediction of treatment responses in lung cancer patients as well as act as therapeutic targets. This study will provide biomarkers for lung cancer diagnosis and treatments

    Effect of Tinospora cordifolia as an add - on therapy on the blood glucose levels of patients with Type 2 diabetes.
    (2015-05) Mishra, Saumya; Verma, Narsingh; Bhattacharya, Sandeep; Usman, Kauser; Himanshu, D; Singh, Prerana; Anjum, B; Verma, Neera
    Background: Type 2 diabetes is a fast growing epidemic affecting people globally. Good glycemic control helps in reducing the risk of macro and microvascular complications in diabetics. Alternative medicines have been used since ancient times in India to achieve good glycemic control. Tinospora cordifolia (Tc) is a well reported plant possessing anti-diabetic property. Therefore, we undertook this study to evaluate the effectivity of Tc in reducing the blood glucose levels of Type 2 diabetic patients in the form of add-on therapy. Methods: In the present study, we enrolled 100 Type 2 diabetic patients who met our inclusion criteria. These patients were then randomly divided into two Groups, A and B. Patients in Group A were treated as controls and they continued with their anti-diabetic medications. In Group B, Tc was added to the conventional treatment at a dose of 500 mg 3 times daily along with meals. The fasting and postprandial blood glucose levels and glycosylated hemoglobin (HbA1c) were recorded baseline and after 6 months. Results: During the course of study, we observed a decrease in the fasting, postprandial, and HbA1c levels of the patients. However, this decrease was found to be more statistically significant (pā‰¤0.005) in Group B. Conclusion: The results obtained from the present study conclude that Tc, when given in the form of add-on therapy, was found to be synergistic and effective in the better management of Type 2 diabetes. The drug was well tolerated by the patients and no adverse drug event was recorded.

    Efficacy and safety of Tinospora cordifolia (Tc) as an add-on therapy in patients with type-2 diabetes.
    (2015-05) Mishra, Saumya; Verma, Narsingh; Bhattacharya, Sandeep; Usman, Kauser; Reddy, Himanshu; Verma, Neera; Anjum, Baby; Bharadwaj, Shipra; Bharadwaj, Kshitij
    Background: Type 2 diabetes has become a global epidemic. Tinospora cordifolia is being used in the treatment of type 2 diabetes since ancient times. It is a common misconception that Ayurvedic medicines are always safe. In fact, they also pose serious health risks either in the form of adverse reactions or in the form of drug interactions. Hence this study was undertaken to study the efficacy and safety of Tc on human subjects. Methods: We recruited 40 type 2 diabetic patients who were on oral hypoglycaemic agents. These patients were then randomly divided into two groups, A and B. Patients in group A continued with their anti-diabetic medications while in group B Tc was given at a dose of 500 mg three times daily along with their conventional medications. The fasting and post prandial blood glucose levels, renal function tests and liver function tests were recorded at baseline, 3 months and 6 months. Results: During the course of study we observed a decrease in the fasting and post prandial blood glucose levels of the patients. No significant change was observed in the renal function tests and liver function tests and no other event of any adverse drug reactions were recorded. Conclusion: Tinospora cordifolia (Tc) is effective as an add-on therapy in patients with type-2 diabetes. There is no negative impact of Tc on the renal as well as liver function tests.

    Hospital-based study on demographic, hematological, and biochemical profile of lung cancer patients
    (Wolters Kluwer India Pvt. Ltd., 2020-09) Gaur, Priyanka; Bhattacharya, Sandeep; Kant, Surya; Kushwaha, RA S.; Garg, Rajiv; Pandey, Sarika; Dubey, Abhishek
    Background: Lung cancer is considered as the most commonly diagnosed cancer. It is the leading cause of cancer-related mortality. Smoking and environmental pollutants act as important risk factors in majority of lung cancer cases (80%ā€“90%). Material and Methods: This is a hospital-based study carried on in lung cancer patients of North India. Demographic profile of lung cancer patients was recorded. Hematological and biochemical profiles of lung cancer patients and healthy controls were compared. Results: Highest proportion of lung cancer was found in the age group of 46ā€“60 years. Lung cancer was seen in highest number in male gender (76.63%) and also in those patients belonging to the rural category (84.58%). In this study, only 3.98% lung cancer patients having the past history of cancer and 5.47% showing the family history of cancer. Significant differences were found in weight and body mass index (BMI) of lung cancer patients when compared to healthy control (P < 0.0001). Hemoglobin (Hb) was found lower in lung cancer patients as compared with healthy controls. Significant difference was also observed in Hb levels of these two groups (P < 0.000). The serum protein level was lower in lung cancer patients than healthy controls. A significant difference was also observed in the protein levels of these two groups (P < 0.0001). Serum alkaline phosphatase (ALP) levels were higher in lung cancer patients in comparison to healthy controls. A significant difference was also observed in serum ALP levels in lung cancer patients as compared with healthy controls (P < 0.0001). Conclusions: Significant difference between BMI, Hb, serum albumin, and total protein was found in this study. These biomarkers may be helpful in the diagnosis of lung cancer at early stage and also in the follow-up assessment of the effects of treatment

    Improvement in oxidative status with yogic breathing in young healthy males.
    (2002-07-05) Bhattacharya, Sandeep; Pandey, U S; Verma, N S
    The modern living lifestyle is known to produce various physical and psychological stresses and subject the individual to produce oxidative stresses as well. The aim of this study has been to assess the effect of yogic breathing exercises (pranayama) on the oxidatives stress. The study group consisted of 30 young male volunteers, trained for the purpose of this study and an equal number of controls were used. The free radicals and Super oxide dismutase levels were measured before the study and at the end of the study. The free radicals were decreased significantly in the study group but the SOD was increased insignificantly as compared to the control group. Yogic breathing exercises not only help in relieving the stresses of life but also improve the antioxidant status of the individual. An improvement in the antioxidant status is helpful in preventing many pathological processes that are known with impaired antioxidant system of body.
