Molecular Signature of the Immune Response to Yoga Therapy in Stress-related Chronic Disease Conditions: An Insight.

The world Health Organization defines health as complete well-being in terms of physical, mental and social, and not merely the absence of disease. To attain this, individual should adapt and self-mange the social, physical and emotional challenges of life. Exposure to chronic stress due to urbanization, work stress, nuclear family, pollution, unhealthy food habits, lifestyle, accidental death in the family, and natural calamities are the triggering factors, leading to hormonal imbalance and inflammation in the tissue. The relationship between stress and illness is complex; all chronic illnesses such as cardiovascular disease and asthma have their root in chronic stress attributed by inflammation. In recent times, yoga therapy has emerged as an important complementary alternative medicine for many human diseases. Yoga therapy has a positive impact on mind and body; it acts by incorporating appropriate breathing techniques and mindfulness to attain conscious direction of our awareness of the present moment by meditation, which helps achieve harmony between the body and mind. Studies have also demonstrated the important regulatory effects of yoga therapy on brain structure and functions. Despite these advances, the cellular and molecular mechanisms by which yoga therapy renders its beneficial effects are inadequately known. A growing body of evidence suggests that yoga therapy has immunomodulatory effects. However, the precise mechanistic basis has not been addressed empirically. In this review, we have attempted to highlight the effect of yoga therapy on immune system functioning with an aim to identify important immunological signatures that index the effect of yoga therapy. Toward this, we have summarized the available scientific evidence showing positive impacts of yoga therapy. Finally, we have emphasized the efficacy of yoga in improving physical and mental well-being. Yoga has been a part of Indian culture and tradition for long; now, the time has come to scientifically validate this and implement this as an alternative treatment method for stress-related chronic disease.

Evaluation of high sensitivity C-reactive protein and glycated hemoglobin levels in diabetic nephropathy.

Diabetic nephropathy (DN) is one of the major long-term complications of diabetes mellitus (DM). Type 2 DM is frequently associated with an inflammatory status, but limited information is available on the relationship between low-grade inflammation and DN. The aim of the study is to determine the serum level of high sensitivity C-reactive protein (hsCRP) in DN patients and to compare with that of normal subjects and to study the association between serum hsCRP levels and glycated hemoglobin (HbA1c) levels. Fifty DN patients in the age group of 50- 60 years with more than ten years of duration of diabetes were recruited for this study and 25 age-and sex-matched healthy subjects were included in this study as controls. Serum hsCRP levels were measured by turbidometry method. There was a statistically significant increase in serum hsCRP levels in DN cases as compared to normal controls. The hsCRP levels showed a positive correlation with HbA1c in DN. These results suggest that estimation of serum hsCRP levels and aiming at good glycemic control help in early intervention and prevention of further com-plications in diabetic patients.

Utility of blood DNA levels in diagnosis of breast cancer.

BACKGROUND: Prognostic factors, including both histopathological and biochemical variables, influence the choice of modality and the course of therapy in breast cancer. The biomarkers found in biological fluids, particularly in blood, apparently hold the best promise for the development of screening assays. AIM: To find out if any correlation exists between blood DNA level and tumor stage, size and grade. MATERIALS AND METHODS: This case-control study was carried out on 52 female patients in the age-group of 18-70 years. The cases comprised 25 patients with histopathologically confirmed malignant breast cancer, while 27 patients with benign breast tumors served as the control group. STATISTICAL ANALYSIS: We used the Student's 't' test to compare the differences between the blood DNA levels in the two groups. Pearson's test was performed to find out the correlation between blood DNA levels and the TNM stage, tumor size and grade. RESULTS: It was observed that blood DNA levels showed statistically significant correlation with the TNM stage, tumor size and grade. CONCLUSION: The blood DNA level can be utilized as a noninvasive marker to assess tumor aggressiveness. Thus, it can be useful as a prognostic marker and as a marker of tumor burden.

Usefulness of serum CA 15.3 and histopathological prognostic indices in breast cancer.

Prognostic factors influence the modality and course of therapy in breast cancer. These include both histopathological and biochemical variables. This study was aimed to find out if any correlation exists between the biochemical tumor marker-serum CA 15.3, and the lymph node staging of Nottingham's Prognostic Index (NPI). It was observed that serum CA 15.3 showed a statistically significant correlation with lymph node staging of NPI. Therefore it is concluded that CA 15.3 can be utilized as a useful prognostic marker, particularly in cases where histopathological variables such as tumor size and grade have been altered by pre-operative chemotherapy.

Evaluation of serum glycoproteins in oral carcinoma.

The present study was conducted on thirty untreated oral cancer patients proved by clinical and histopathological evidence and thirty healthy control subjects. The levels of glycoprotein-associated carbohydrates such as hexose, hexosamine, fucose and sialic acid were found to be elevated significantly as compared to control subjects. There was a progressive rise in these markers as the stages of oral cancer advanced.
