Abstract
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). LSKY is a sequential combination of pranayama in ujjayi breath, bhastrika, and cyclic rhythmic breathing followed by yog-nidra. METHODS Regular LSKY practitioners from the Art of Living community with more than two years of experience participated in the study (n = 22; age 40.09 ± 12.68). The Electrocardiogram (ECG), respiration, oxygen saturation, and concentrations of oxygen and carbon-di-oxide from exhaled air were recorded before and during LSKY. The time domain parameters of heart rate variability (HRV) were calculated from ECG. All parameters were compared and correlated at each stage of LSKY. RESULTS Highly significant reciprocal correlation was found between HRV parameters and respiration rate during LSKY. Both O2 consumption and CO2 production increased significantly during three stages of pranayama and decreased towards the end of cyclic breathing. We also saw increased SPO2 simultaneously. CONCLUSION The autonomic parameters exhibited reciprocal response to respiratory rate and correlated well to the ventilatory parameters. Further during LSKY we observed enhanced synchronization. In conclusion the LSKY has a potential to influence cardiorespiratory parameters for improving the performance of both systems. LSKY - enhances oscillations in HRV that resets the autonomic system, indicative of better cardiac health and prepares body for better metabolic response. Such changes are capable of inducing resilience along with physiological, psychological relaxation and emotional well-being.

Abstract
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). Methods A total of 97 healthy volunteers participated in the study, distributed into two groups. The Group I SKY practitioners attended a four-day AMP (50 participants with an average age of 38.8 ± 11.9 consisting of 37 females and 13 males); they are first-time participants of the AMP. Group II SKY practitioners, on the other hand, consisted of 47 participants with an average age of 36.4 ± 9.3 with 43 females and four males. At day 0, day 5, and day 90, the mRNA expression of pro-inflammatory genes, namely interleukin (IL) 1β, IL6, and the tumor necrosis factor (TNF), and the expression of antioxidative genes, namely superoxide dismutase (SOD), catalase, and glutathione peroxidase (GPx) was observed. The data were analysed in two phases due to the emergence of coronavirus disease 2019 (COVID-19): (i) pre-COVID-19 and (ii) during COVID-19. Results In the pre-COVID-19 data set, IL1β, IL6, and TNF were found to have decreased in both groups. There is a significant increase in the expression of SOD and catalase in Group I and a decrease in Group II by day 90. During COVID-19, pro-inflammatory genes increased in Group I and had no significant change in Group II. All three antioxidant genes had decreased expression by day 90 in Group I; SOD decreased in Group II. Interpretation and conclusions Reduced expression of pro-inflammatory genes and increase in the expression of antioxidative genes during the pre-COVID-19 time suggest that the practice of SKY and added AMP may enhance antioxidative defense and may reduce the chance of getting diseases related to inflammation in the body.

Abstract
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. FLCM was prepared by incubating fetal liver cells with Iscove's Modified Dulbecco's Medium (IMDM) containing 10% fetal bovine serum (FBS) and 10% Phytohemagglutinin and collected after 24hrs, 48hrs, 72 hrs. and on the 7th day of incubation. Clonal cultures were established for 1 X 105 normal bone marrow (BM) mononuclear cells (NBM MNC) per plate with methylcellulose medium containing cytokines SCF and EPO. Mean Colony forming units-granulocytes, erythrocytes, macrophages, megakaryocytes (CFU-GEMM) were assessed with and without the addition of FLCM. It was found that FLCM enhanced the number of colonies made by NBM MNCs. Further, cytokines IL-6 and Flt-3, present in FLCM, were bioneutralized with respective anti-cytokine antibodies. Neutralized FLCM was evaluated for the colony-forming potential of CFU-GEMM colonies. The maximum reduction of 42% was seen with 20 ng/ml of anti-IL-6 antibody. Maximum suppression up to 20% was observed with 0.7 ng/ml of anti Flt-3 antibody for CFU-GEMM colonies. Presence of cytokines IL-6 and Flt-3 in FL extracts and their colony stimulatory activity suggests that fetal liver infusion (FLI) may be a valuable alternative for managing BM recovery in certain clinical conditions such as AA.

Abstract
Traditionally, chronic calcineurin inhibitor (CNI) nephrotoxicity has been considered to be one of the main nonimmune mechanisms causing chronic renal allograft dysfunction. CNI minimization and withdrawal strategies have yielded inconsistent results. Few studies address the feasibility of CNI elimination in a prednisone-free regimen. We report a prospective, randomized trial in 200 patients evaluating the impact on renal function and incidence of acute rejection after conversion from tacrolimus (Tac) to sirolimus (SRL). Patients with recent (<3 months) acute rejection episodes or with >0.5 g/day of proteinuria were excluded. All were induced with alemtuzumab, underwent rapid steroid elimination and were maintained on mycophenolate mofetil and Tac. At 12 months posttransplant, patients were randomized 2:1 to SRL (n = 123) or maintained on Tac (n = 64). Mean follow-up was 41.1 ± 15.8 months in the SRL group and 40.7 ± 14.4 months in the Tac group. Biopsy-proven acute rejection at 24 months postrandomization was similar between the groups. Patient survival, graft survival and estimated GFR were also not statistically different. Our study demonstrates that in a prednisone-free immunosuppressive regimen, conversion from Tac to SRL at 12 months posttransplantation is not associated with increased rates of acute rejection and graft loss. However, despite CNI elimination, renal allograft function is equally maintained in both groups.

Abstract
Introduction: Several new medications are now available for immunosuppression in the kidney transplant field. Tacrolimus and mycophenolate mofetil were first introduced for immunosuppression in renal transplantation in the mid 1990s. Since then, the combination of tacrolimus and mycophenolate mofetil has been evaluated in numerous clinical trials. The outcomes of these trials have varied due to differences in induction and/or maintenance therapy, drug dosing and monitoring protocols, and study design. The aim of this review is to analyze the literature critically and to provide an overview of tacrolimus and mycophenolate mofetil combination therapy in renal transplantation.

Abstract
Idiopathic membranous nephropathy (IMN) remains the most common histologic entity associated with adult-onset nephrotic syndrome. The therapy for IMN is challenging. Steroids and various other immunosuppressive agents have been tried in IMN; however, current agents have not altered the course of IMN, are nonspecific and can be very toxic. In native kidneys affected by IMN, rituximab, a monoclonal antibody against the B-cell surface antigen CD20, has been shown to reduce proteinuria and prevent disease progression. In this report, we describe a 39-year-old white male with end-stage renal disease secondary to IMN that, 4 months post living unrelated kidney transplant, developed recurrent IMN with 18 g/day of proteinuria. In addition to angiotensin converting enzyme inhibitor and statins, the patient was treated with 4 weekly doses of 375 mg/m2 of rituximab with significant reduction in proteinuria, a corresponding increase in serum albumin and improvement in hypercholesterolemia. At 3 years post-transplant, his kidney function remains stable with 0.5 g/day of proteinuria.

Abstract
Though surgical resection is the main stay of treatment for childhood hepatoblastoma (HB), many are unsuitable for radical surgery at diagnosis due to extensive intrahepatic and/or extra hepatic disease. We report experience in five patients of HB from a single institution (2001-2005) with preoperative Neoadjuvant chemotherapy (NACT) followed by surgery. Three patients received cisplatin, doxorubicin; and two cisplatin / vincristine /5-fluorouracil. All showed more than 50% reduction in tumor size confirmed by CT scan. Hepatic resection R0 was performed in all. There was no chemotherapy related toxicity nor post surgical morbidity or mortality. All are disease free at median follow up of 4 years. NACT produces adequate down staging of the HB with acceptable toxicity. Though cisplatin with doxorubicin produced good results, new protocol with cisplatin, vincristine and 5FU is promising without cardiotoxicity.

Abstract
Actin is the principal component of microfilaments. Its assembly/disassembly is essential for cell motility, cytokinesis, and a range of other functions. Recent evidence suggests that actin is present in the nucleus where it may be involved in the regulation of gene expression and that cofilin binds actin and can translocate into the nucleus during times of stress. In this report, we combine fluorescence resonance energy transfer and confocal microscopy to analyze the interactions of cofilin and G-actin within the nucleus and cytoplasm. By measuring the rate of photobleaching of fluorescein-labeled actin in the presence and absence of Cy5-labeled cofilin, we determined that almost all G-actin in the nucleus is bound to cofilin, whereas approximately (1/2) is bound in the cytoplasm. Using fluorescence resonance energy transfer imaging techniques we observed that a significant proportion of fluorescein-labeled cofilin in both the nucleus and cytoplasm binds added tetramethylrhodamine-labeled G-actin. Our data suggest there is significantly more cofilin-G-actin complex and less free cofilin in the nucleus than in the cytoplasm.

Abstract
The actin cytoskeleton is a complex structure that performs a wide range of cellular functions. In 2001, significant advances were made to our understanding of the structure and function of actin monomers. Many of these are likely to help us understand and distinguish between the structural models of actin microfilaments. In particular, 1) the structure of actin was resolved from crystals in the absence of cocrystallized actin binding proteins (ABPs), 2) the prokaryotic ancestral gene of actin was crystallized and its function as a bacterial cytoskeleton was revealed, and 3) the structure of the Arp2/3 complex was described for the first time. In this review we selected several ABPs (ADF/cofilin, profilin, gelsolin, thymosin beta4, DNase I, CapZ, tropomodulin, and Arp2/3) that regulate actin-driven assembly, i.e., movement that is independent of motor proteins. They were chosen because 1) they represent a family of related proteins, 2) they are widely distributed in nature, 3) an atomic structure (or at least a plausible model) is available for each of them, and 4) each is expressed in significant quantities in cells. These ABPs perform the following cellular functions: 1) they maintain the population of unassembled but assembly-ready actin monomers (profilin), 2) they regulate the state of polymerization of filaments (ADF/cofilin, profilin), 3) they bind to and block the growing ends of actin filaments (gelsolin), 4) they nucleate actin assembly (gelsolin, Arp2/3, cofilin), 5) they sever actin filaments (gelsolin, ADF/cofilin), 6) they bind to the sides of actin filaments (gelsolin, Arp2/3), and 7) they cross-link actin filaments (Arp2/3). Some of these ABPs are essential, whereas others may form regulatory ternary complexes. Some play crucial roles in human disorders, and for all of them, there are good reasons why investigations into their structures and functions should continue.

Abstract
Actin is the major cytoskeletal protein of virtually all eukaryotic cells. Actin assembly/disassembly is involved in a variety of cellular processes and actin-binding proteins are essential in regulation of the pool of actin monomers. Cofilin and DNase I are actin-binding proteins, which form both binary (actin-DNase 1, cofilin-actin) and ternary (cofilin-actin-DNase I) complexes with actin. Here we use native gel electrophoresis to examine the roles of ATP, ADP, Ca2+ and Mg2+ in the formation of these complexes as well as on the ability of actin to self-assemble. Conditions which favour actin polymerisation are: ATP (no Me2+) > or = ADP (no Me2+) > ADP-Ca2+ = ADP-Mg2+ > ATP-Mg2+ > ATP-Ca2+. Preferential conditions for the formation of the binary actin-cofilin complex are: ADP-Mg2+ > or = ADP-Ca2+ >> ATP-Ca2+ approximately equals ATP-Mg2+ approximately equals ADP-No Me2+ approximately equals ATP-No Me2+. Actin forms a very tight complex with DNase I in the order: ATP-Ca2+ > or = ATP-Mg2+ approximately equals ADP-Mg2+ approximately equals ADP-Ca2+ > or = ADP-(no Me2+) > ATP-(no Me2+). Effectively, the complex does not form in the presence of ATP and the absence of free Me2+. Finally, the conditions which favour the formation of a ternary complex of cofilin-actin-DNase I resemble the actin-DNase I, namely: ATP-Ca2+ approximately equals ADP-Ca2+ approximately equals ADP-Mg2+ approximately equals ATPMg2+ ADP (no Me2+) > ATP-(no Me2+).
