Abstract
Covalent histone modifications, chromatin remodeling and incorporation of histone variants regulate the dynamics of chromatin structure. Among covalent histone modifications, histone methylation mediates by histone methylases that influence the gene expression in heterochromatin silencing, genomic imprinting and transcription. In contrast to methylases, histone demethylases remove the methyl groups from lysine or arginine residues of histones and have enormous impact on gene expression via modified chromatin structures. Two types of histone lysie demethylases have been identified, including lysine specific demethylases 1 (LSD1) and Jmj (Jumonji) domain containing family proteins. The human demethyliminase (PADI4) converts monomethyl arginine residue to citrulline by the arginine demethylimination. In this review we summarize recent advances to understand the mechanism of demethylases in regulation of plant gene expression. In addition we are highlighting the function of four human like LSD1 (LDL) and jmj domain containing genes of Arabidopsis that regulate the defense related, flowering controlling and brassinosteroid response genes.

Abstract
OBJECTIVES To evaluate the effectiveness of the Bathing Without a Battle intervention in reducing physical and verbal aggressive behaviors for nursing home residents with dementia. DESIGN A randomized crossover diffusion study, with one group receiving the intervention after one round of baseline observations and a delayed intervention group receiving the intervention after two rounds of baseline observations. SETTING Six nursing home facilities in the state of New York. PARTICIPANTS Nursing home residents with dementia (N = 240). INTERVENTION The Bathing Without a Battle educational program, designed for direct-care staff members responsible for bathing residents diagnosed with dementia and implemented through a train-the-trainer model. MEASUREMENTS Rates of verbal and physical aggressive and agitated behaviors were measured using the Care Recipient Behavior Assessment; secondary measures of effect included bath duration, bath modality, and antipsychotic medication use. RESULTS In spite of implementation obstacles (consent delays and change in leadership at one facility), a significant change was observed in how residents were bathed that translated into a significant reduction in the rate of aggressive and agitated behaviors, particularly verbal, during residents' baths. The use of in-bed baths increased 17%, and average bath duration decreased significantly (average 1.5 minutes less) in the postintervention period, particularly for in-bed baths. Verbal behaviors declined 17.8% (P = .008), combined verbal and physical behaviors declined 18.6% (P = .004), and antipsychotic use declined 30% (P = .002) after the intervention. CONCLUSION The Bathing Without a Battle educational program, delivered through a train-the-trainer format, is an effective means of improving the bathing experience of residents with dementia in nursing homes. This research supports broadly adopting this intervention, especially for nursing homes serving many residents with dementia.

Abstract
To assess the protective effects of Eugenia jambolana extract (EJE) or N-acetyl cysteine (NAC) on testis, cisplatin (CIS, 5 mg kg(-1) bw, single dose) was administered either alone or along with EJE (25 mg kg(-1) bw, alternate day) or NAC (150 mg kg(-1) bw, Day 1 and 4) for 7 days. Significant alterations in serum LH, FSH and testosterone were observed in CIS group which were effectively modulated by EJE or NAC supplementation. Upregulation of 3β-HSD gene indicated the rise in functional Leydig cells. This was further confirmed from the identical improvement in hCG-stimulated testosterone production in isolated Leydig cells. Reduction in oxidative stress was associated with restoration of total antioxidant capacity and glutathione levels, and activation of antioxidant enzymes, SOD, catalase, glutathione s-transferase (GST) and glutathione reductase (GR). CIS-induced apoptosis of germ and Leydig cells was contained by both NAC and EJE intervention by effective modulation of apoptotic markers in the extrinsic, intrinsic and other pathways of metazoan apoptosis. Taken together, the study findings establish the potential of EJE as a therapeutically better antioxidant than NAC for use in curtailing the adverse effects of anticancer drugs on testicular function.

Abstract
CONTEXT Acute viral hepatitis (AVH) is a major public health problem and is an important cause of morbidity and mortality. AIM The aim of the present study is to determine the prevalence of hepatitis A virus (HAV), hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV) and hepatitis E virus (HEV) as causes of AVH in a tertiary care hospital of North India. SETTINGS AND DESIGN Blood samples and clinical information was collected from cases of AVH referred to the Grade I viral diagnostic laboratory over a 1-year period. SUBJECTS AND METHODS Samples were tested for hepatitis B surface antigen, anti-HCV total antibodies, anti-HAV immunoglobulin M (IgM) and anti-HEV IgM by the enzyme-linked immunosorbent assay. PCR for nucleic acid detection of HBV and HCV was also carried out. Those positive for HBV infection were tested for anti-HDV antibodies. STATISTICAL ANALYSIS USED Fisher's exact test was used and a P < 0.05 was considered to be statistically significant. RESULTS Of the 267 viral hepatitis cases, 62 (23.22%) patients presented as acute hepatic failure. HAV (26.96%) was identified as the most common cause of acute hepatitis followed by HEV (17.97%), HBV (16.10%) and HCV (11.98%). Co-infections with more than one virus were present in 34 cases; HAV-HEV co-infection being the most common. HEV was the most important cause of acute hepatic failure followed by co-infection with HAV and HEV. An indication towards epidemiological shift of HAV infection from children to adults with a rise in HAV prevalence was seen. CONCLUSIONS To the best of our knowledge, this is the first report indicating epidemiological shift of HAV in Uttar Pradesh.

Abstract
BACKGROUND Maternal position affects spinal block characteristics. We investigated the effect of lateral, modified lateral and sitting position for spinal anesthesia with 2 mL hyperbaric bupivacaine 0.5% on spinal block characteristics in this prospective, randomized study. METHODS Seventy-five ASA physical status I parturients were randomly allocated to the left lateral to supine-wedged, modified lateral to supine-wedged with a10°head-up tilt or the sitting to supine-wedged position for induction of spinal anesthesia for Cesarean delivery. Neural block was assessed by pin prick and modified Bromage scale. Data were analyzed using ANOVA, Chi-square test and Wilcoxon rank sum test, where appropriate. P<0.05 was considered significant. RESULTS Onset time (mean ± SD) for sensory block to T5 dermatome for the lateral, modified lateral and sitting groups was 6.8 ± 2.7, 13.6 ± 6.2 and 9.7 ± 5.5 min, respectively; P<0.001. The median (interquartile range) maximum dermatomal level was significantly lower in the modified lateral group (T5[T3-T5]) compared with the lateral (T3[T2-T4]) and sitting (T3[T3-T4]) groups, respectively; P=0.022 and P=0.030, respectively. Three women in the modified lateral group required general anesthesia compared with none in the other groups; P= 0.044. Apgar scores and cord blood pH, PO2 and PCO2 were similar between groups. CONCLUSION The modified lateral position with 10 mg of hyperbaric bupivacaine was associated with a slower onset and a lower maximum sensory block necessitating higher requirement for conversion to general anesthesia. It did not offer any advantage over lateral and sitting positions for induction of spinal anesthesia for elective Cesarean delivery and cannot be recommended.

Abstract
Contraceptive properties of seaweeds are still stands as lacuna; in this context, the screening of in vitro male contraceptive properties of crude ethanolic extract of Indian seaweeds against normal human sperm is carried out. In total, twelve seaweeds were screened for in vitro spermicidal activity. Among these twelve seaweeds, Halimeda gracilis showed 100% inhibition of human spermatozoa at 10 mg ml(-1) concentration in 20 s and its EC50 value was 2.05 mg ml(-1) in 20 s. Further, dose- and time-dependent spermicidal assay revealed that the sperm was completely immobilised for 20 s. Plasma membrane of sperm was damaged due to the exposure of H. gracilis extract. MTT assay with H. gracilis extract showed 88.5% of cytotoxic incidence. H. gracilis extract tested for cytotoxicity against Artemia salina recorded LC50 value of 34.8 μg ml(-1) . Phytochemical analysis of H. gracilis extract evidenced the presence of alkaloids, flavonoids, proteins and sugars. Results of this study clearly inferred that the synergistic effect of active principles reside within the H. gracilis extract had shown better contraceptive activity.

Abstract
The present study evaluated reproductive toxicity and antifouling activity of methanolic extract of seagrass Syringodium isoetifolium (25 μg/ml) relative to the conventional antifoulant, tributyltin (TBT; 100 ng/l) on the ovarian development of the brown mussel Perna indica. Gonado Somatic Index (GSI) and Digestive Gland Index (DGI) of TBT exposed mussels decreased in comparison with mussels exposed to S. isoetifolium extract. Interestingly, mussels treated with S. isoetifolium showed normal cellular architecture in gills, digestive gland, muscle and ovary. However, TBT increased interfilamental space and fusion of the filaments in gills, disruption in the digestive tubules and reduction in basement membrane thickness. Besides in adductor muscle, TBT induced muscle degeneration, and necrotic muscle layer. In ovary, TBT inflicted the fusion of developing oocytes. TBT had significantly retarded the ovarian development and substantially affected the biochemical constituents leading to an impairment of oogenesis as against the null effects noticed from the S. isoetifolium extract treated mussels. On the ground of eco-friendly properties, the seagrass S. isoetifolium could be used as a source for the production of green antifoulant.
