Transduction of Human Fetal Liver Hematopoietic CD34+ Stem and Progenitor Cells into a Cell Line by Enhancing Telomerase Activity.

: Human fetal liver hematopoietic stem cells have proven potential as therapeutics but lack extensive research due to their limited supply. Even expanded fetal liver hematopoietic stem cells enter senescence or lose their self-renewal capacity after a few days in culture. The present study aimed to obtain a homogeneous and persistent supply of hematopoietic stem cells from the fetal liver by establishing a cell line through immortalization of cells by enhancing telomerase activity.

Long Sudarshan Kriya Yoga enhances cardiovascular and respiratory synchronization: An observational study.

Background: Sudarshan Kriya Yoga (SKY - a rhythmic cyclic breathing) is known to produce several physiological changes in human body. Earlier it has been reported that SKY improves cardiovascular modulations, namely increase in heart rate variability.

Objective: To observe the synchronization in oscillatory modulations in cardiac autonomic tone and ventilatory exchange during Long Sudarshan Kriya Yoga (LSKY).

Effects of Sudarshan KriyaYoga and Advanced Meditation Program on Genetic Expression of Pro-inflammatory and Antioxidants Genes.

Background Stress leads to immune system dysregulation and dyshomeostasis at the gene level. Mind-body practices are known to influence genomic expression, leading to better health and quality of life. Objective To assess the effect of Advanced Meditation Program (AMP) on the mRNA expression of pro-inflammatory and antioxidative genes among those already practicing Sudarshan Kriya Yoga (SKY).

Effect of fetal liver condition media derived cytokines(IL-6 and Flt-3) on human bone marrow stem cells colony formation.

Earlier research from our laboratory demonstrated the presence of stimulatory activity of different growth factors in the fetal liver (FL) extracts when collected in a medium known as fetal liver conditioned medium (FLCM) using Enzyme-linked Immunosorbent Assay (ELISA). In the present study, we have assessed two other cytokines viz. IL-6 and FMS like tyrosine kinase-3 (Flt-3) with the help of bioneutralization assay.

In vitro expansion of fetal liver hematopoietic stem cells.

Fetal liver hematopoietic stem and progenitor cells (HSPCs) have been considered appropriate for the management of aplastic anemia owing to their proliferative potential. Bone marrow recovery was possible in some cases; the engraftment potential of these cells, however was unsatisfactory, possibly due to the availability of a smaller number of these cells from a single fetus. The present study explores how we can expand fetal liver hematopoietic stem cells under in vitro conditions.

Effect of Sudarshan Kriya Yoga (SKY) on daytime and situational sleep propensity in novice practitioners: a prospective cohort study.

Acute promyelocytic leukemia: an experience from a tertiary care centre in north India.

Background: There are very limited data reported about acute promyelocytic leukemia (APL) from developing countries. We reviewed the clinical course and treatment outcome of APL patients treated at our center.

Materials And Methods: Between January 1997 and December 2007, 33 patients with APL received induction therapy using ATRA + daunorubicin (n = 26), As = 26), As2O3 (n = 4) or daunorubicin + cytosar ( n = 3).

Detection of cancer by optical analysis of body fluids--a single blind study.

This paper pertains to a new technique based on fluorescence emission spectra (FES), and stokes shift spectra (SSS) of blood plasma, acetone extract of cellular fraction, and urine. These samples were collected from 60 cancer patients of different etiology and 60 age adjusted controls for a single blind study. A set of ratio parameters were obtained from the above spectra (FES and SSS of above three sets of samples), based on the relative intensity of biofluorophores like tryptophan, tyrosine, flavin etc.

Mutations in ABL kinase domain are associated with inferior progression-free survival.

Imatinib mesylate is currently the drug of choice for all phases of chronic myeloid leukemia (CML). Despite the initial high rates of hematological and cytogenetic responses, many patients develop resistance. We prospectively studied 40 patients with CML with primary cytogenetic resistance to imatinib mesylate.

Response to Imatinib mesylate in chronic myeloid leukemia patients with variant BCR-ABL fusion transcripts.

Chronic myeloid leukemia patients with different BCR-ABL transcripts might respond differently to Imatinib mesylate. This prompted us to study BCR-ABL transcripts in chronic myeloid leukemia (CML) patients and their correlation with response to Imatinib. Eighty-seven chronic phase CML patients (median age, 35 years; range, 13-62 years; M/F, 59:28) were included in this study; 57 patients had received interferon-alpha and/or hydroxyurea, and 30 were previously untreated.

High-dose chemotherapy with autologous stem cell transplantation for multiple myeloma: what predicts the outcome? Experience from a developing country.

We analyzed the results of 108 patients (78 males and 30 females) with multiple myeloma who underwent autologous stem cell transplantation (ASCT). The median age of patients was 52 years (range, 26-68 years). High-dose melphalan (200 mg/m(2)) was used for conditioning.

Gene expression profiling in practitioners of Sudarshan Kriya.

Background: The rapid pace of life, eating habits, and environmental pollution have increased stress levels and its related disorders. The complex molecular response to stress is mediated by stress genes and a variety of regulatory pathways. Oxidative stress is internal damage caused by reactive oxygen species.

Primary pulmonary rhabdomyosarcoma in adults: case report and review of literature.

A 38-year-old man, a chronic smoker, presented to us with a large left upper lobe mass lesion and left-sided pleural effusion. After resection, a residual mass remained. On histopathologic examination, a diagnosis of pleiomorphic rhabdomyosarcoma stage III of the lung was made.

Multifocal osteosarcoma involving unusual sites.

We report a rare case of multifocal osteosarcoma (MFOS) with involvement of skeleton, lung, bone marrow, and soft tissues, presenting with paraparesis, cranial nerve palsies, subcutaneous nodules, anemia, and thrombocytopenia. MFOS with involvement of unusual sites presents problems in diagnosis and has a poor prognosis. The literature on 11 cases of MFOS with extraosseus, extrapulmonary involvement reported previously has been reviewed.

Recent advances in the mangement of multiple myeloma.

The management of multiple myeloma has undergone a major change during the past decade. Currently, patients < 65 years of age with advanced disease (stage II-III) are best treated with initial chemotherapy (3-4 cycles of vincristine, adriamycin and dexamethasone, or vincristine, adriamycin and methyl prednisolone, or thalidomide and dexamethasone followed by high dose chemotherapy with autologous peripheral blood stem cell transplantation. More than 50% of patients achieve complete response following this approach.

Small cell lung cancer: an update on therapeutic aspects.

Small cell lung cancer comprises approximately 20% of all lung cancers and continues to be a difficult management issue. More than two-thirds of cases present with extensive disease, which has spread beyond the himithorax and regional ipsilateral nodes. While response rates to chemotherapy are relatively high, durable responses are rare, and long-term survival rates are anecdotal.

Evaluation of the effect of Withania somnifera root extracts on cell cycle and angiogenesis.

In the Indian System of Medicine, the medicinal plant, Withania somnifera Dunal (Solanaceae) finds application for numerous ailments including cancer. This study explores the mechanism(s) underlying this property. The hydroalcoholic extract of the roots (WS) was partitioned between chloroform (WS-chloroform) and water (WS-water).

Effect of rhythmic breathing (Sudarshan Kriya and Pranayam) on immune functions and tobacco addiction.

Stress, a psychophysiological process, acts through the immune-neuroendocrine axis and affects cellular processes of body and immune functions, leading to disease states including cancer. Stress is also linked to the habit of tobacco consumption and substance abuse, which in turn also leads to diseases. Sudarshan Kriya (SK) and Pranayam (P), rhythmic breathing processes, are known to reduce stress and improve immune functions.

Quality of life measures in lung cancer.

Lung cancer is one of the leading causes of cancer death worldwide. Survival has not improved significantly in spite of newer therapies. In view of the high-symptom burden and severe morbidity, evaluation of quality of life (QOL) becomes important in these patients.
