Abstract
Semecarpus anacardium L.f. has been commonly used in various traditional medicines from ancient times. The nuts have been described in Ayurveda medication systems to treat numerous clinical ailments. However, isolating phytochemical constituents from nuts remain challenging and exhibits cytotoxic effects on other cells. In this study, we have standardized procedures for isolating phytochemicals from the leaf extract. The ethyl acetate leaf extract selectively affects cancer cells in a dose-dependent manner (IC50: 0.57 µg/ml in MCF-7 cells) in various cancer cell lines and induces apoptosis in cancer cells. However, the non-malignant cells were relatively insensitive to the extract. Next, the incubation of the leaf extract induces cell cycle arrest and suppresses cancer cell migration in the cell culture model. Moreover, oral administration of extract significantly restored tumor growth in mice. Together, these observations suggest the anti-cancer activities of S. anacardium L.f. leaf potential for both in vitro and in vivo models.

Abstract
Rice-based integrated farming system improves the productivity and profitability by recycling resources efficiently. In the sub-humid tropics, rice production without sufficient nutrient replenishment often leads to soil health and fertility degradation. There has been very limited research on soil health and fertility after adopting a multi-enterprising rice-based integrated farming system (IFS), notably in the rice-fish-livestock and agroforestry system, when compared to a conventional farming system (CS). Therefore, the present study analyzed the dynamics of soil properties, soil bacterial community structure and their possible interaction mechanisms, as well as their effect on regulating soil quality and production in IFS, IFSw (water stagnant area of IFS) and CS. The results indicated that soil nutrient dynamics, bacterial diversity indices (Shannon index, Simpson index, Chao 1, ACE and Fisher index) and system productivity were higher in IFSw and IFS compared to CS. Moreover, relative operational taxonomic units of dominant bacterial genera (Chloroflexi, Acidobacteria, Verrucomicrobia, Planctomycetes, Cyanobacteria, Crenarchaeota and Gemmatimonadetes) were also higher in IFSw and IFS compared to CS. Mean soil quality index (SQI) was highest in IFSw (0.780 ± 0.201) followed by IFS (0.770 ± 0.080) and CS (0.595 ± 0.244). Moreover, rice equivalent yields (REY) and rice yields were well correlated with the higher levels of soil biological indices (SQIBiol) in IFS. Overall, our results revealed that rice-based IFS improved the soil health and fertility and ensuing crop productivity through positive interaction with soil bacterial communities and nutrient stoichiometry leading to agroecosystem sustainability.

Abstract
Panchvalkal kwath (PK) is a bark formulation of five pharmacologically important plants, i.e., Ficus benghalensis, Ficus racemosa, Ficus religiosa, Thespesia populnea, and Ficus lacor. The Ayurvedic formulation is being used since ancient times to cure diabetes, bacterial infections and heal wounds. The present study aims to identify the metabolite profiles of PK which could explain its properties and its mode of action against specific diseases and disorders. The aqueous extract of Panchvalkal is prepared through a hot maceration process. The extract is subjected to preliminary identification of phytoconstituents and FTIR spectroscopy to recognize functional groups. GC-MS analysis reveals that the extract is enriched with 24-Norursa-3,12-diene (25.16%); Lup-20(29)-en-3-one (16.76%); 2-methyl-3-(4-propan-2-ylphenyl) propanal (7.04%); 2-(hydroxymethyl)-2-nitropropane-1,3-diol (11.21%) and 3,5-dihydroxy-6-methyl-2,3-dihydropyran-4-one (4.15%). The presence of three new phytocompounds that are 4-(hydroxymethyl)-7-methyl-1,3-dioxepane-5,6-diol; 1-(4-isopropylphenyl)-2-methylpropylacetate and 4,4,6 A,6B,8A,11,11,14B-octamethyl-1,4,4A,5,6,6A,8,8a,910,11,12,12a,12b,13,14,14a,14b-ctadecahydro-3(2H)-picenone are detected in the extract. Metabolite profiles of the extract also constitute isoeugenol, stigmasterol, ergosterol, ocimene, myrcene, squalene, sphingosine, betulin, methyl ferulate and cis-jasmone, which are unraveled by 1 D 1H and 2 D 1H-13C HSQC NMR spectroscopy. This article focuses on the presence of different phytocompounds in PK in order to demonstrate its efficacy as a therapeutic formulation for a variety of diseases.

Abstract
The objective of the study was to evaluate the quality of Zamzam water, holy water for Muslims and consumed for its medicinal value. The present study demonstrates the physicochemical characterization and wound healing property of Zamzam water. The physicochemical characterization of Zamzam water samples was analyzed for dissolved oxygen, pH, conductivity, total dissolved solids, redox potential, zeta potential, polydispersity index, and zeta size. The microbial quality of Zamzam water was also assessed by exposing water samples to open air. In this work, Zamzam water was also screened for the medicinal value through wound healing properties in Wistar rats. Zamzam water exhibited a unique physicochemical characterization with high levels of dissolved oxygen, zeta potential, polydispersity index, redox potential, total dissolved solids, and conductivity before exposure to open air. After open air exposure, Zamzam water resisted the growth of bacteria. The wound healing properties of Zamzam water in vivo showed a 96% of healing effect on 12th day observation. The wound healing was achieved by modulating pro-inflammatory cytokine such as interleukin -1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor -α (TNF-α). Followed by the level of apoptosis markers caspase-9 and caspase-3 were reduced. The present study proved that Zamzam water is a good-quality water and showed excellent wound healing property. Therefore, Zamzam water can be used for pharmaceutical formulations.

Abstract
Introduction Substance abuse has traditionally been considered as a disease of men. Women were believed to have some kind of immunity in terms of “social inoculation”. However, due to change in societal norms and beliefs, substance use is currently increasing among women also. Objectives To focus on female substance use in India Methods In India, traditional use of various substances by women during religious festivals is not unknown. Chewing tobacco is a common practice among many women across the country. Cultural use of alcohol has been known in some tribal populations but gradually the use is increasing. There is major difference in pattern of male and female substance use including initiation, progression, recovery and relapse. Women experience greater medical, physiological and psychological impairment and experience loss of control sooner than males. Teatment needs of female substance users is different and requires a gender specific comprehensive strategy which will require medical services, mental health services, services for family and child and employment opportunities. Results Currently, there is no Indian policy for women substance use. However, Government of India has started a convergence program which includes National AIDS Control program (NACP), National rural health mission (NRHM) and reproductive or sexually transmitted infection (RTI/STI) to combat some aspects. Conclusions
India is in great need of a policy or at least a standard operative protocol for management of female substance use disorder which may include screening for substance use disorder for all females accessing health sector, counselling, referral to addiction services, formation of a treating team and after –care. Disclosure No significant relationships.

Abstract
IntroductionOpioid dependent individuals frequently complain of sleep problems in withdrawal and during abstinence.ObjectivesThe objectives were to assess the subjective sleep parameters among buprenorphine-maintained opioid-dependent patients and to correlate it with socio-demographics, concomitant drug use and treatment related variablesMethodsUsing a cross-sectional study design, 106 hundred six opioid-dependent patients maintained on buprenorphine for at least six months and on same dose in past month were interviewed. Sleep was assessed by Pittsburgh sleep quality index (PSQI) and Epworth sleepiness scale. Association between subjective sleep parameters, socio-demographics, concomitant drug use and treatment related variables was also studied.ResultsAll participants were males. Their mean age was 41.1 years (SD:14.3). The mean duration of illicit opioid use was 10 years (IQR: 5,22). About 63.2% (n=67) had PSQI scores more than 5 denoting sleep problem. The scores obtained in Epworth Sleeping Scale were in normal range. Mean subjective total sleep time of the sample was 403.5 (SD 94.8) minutes and median sleep latency was 35 (IQR 18.8, 62.5) minutes. Subjective total sleep time was significantly higher in participants who had use tobacco in the past three months (p value=0.03) and who were in moderate ASSIST risk category (p value=0.04). Subjective sleep latency was significantly higher (p value=0.04) in participants who had used opioids in last three months. It was observed that age was a significant predictor of subjective total sleep time and OST compliance was a significant predictor of sleep latency.ConclusionsA sizeable proportion of opioid dependent patients on buprenorphine have sleep problems

Abstract
Endophytic fungi produce various types of chemicals for establishment of niche within the host plant. Due to symbiotic association, they secrete pharmaceutically important bioactive compounds and enzyme inhibitors. In this research article, we have explored the potent α-glucosidse inhibitor (AGI) produced from Fusarium equiseti recovered from the leaf of Gymnema sylvestre through bioassay-guided fraction. This study investigated the biodiversity, phylogeny, antioxidant activity and α-glucosidse inhibition of endophytic fungi isolated from Gymnema sylvestre. A total of 32 isolates obtained were grouped into 16 genera, according to their morphology of colony and spores. A high biodiversity of endophytic fungi were observed in G. sylvestre with diversity indices. Endophytic fungal strain Fusarium equiseti was identified through DNA sequencing and the sequence was deposited in GenBank database (https://ncbi.nim.nih.gov) with acession number: MF403109. The characterization of potent compound was done by FTIR, LC-ESI-MS and NMR spectroscopic analysis with IUPAC name 17-(5-ethyl-6-methylheptan-2-yl)-10,13-dimethyl-2,3,4,7,8,9,10,11,12,13,14,15,16,17-tetradecahydro-1H-cyclopenta[a] phenanthren-3-ol. The isolated bioactive compound showed significant α-amylase and α-glucosidase inhibition activity with IC50 values, 4.22 ± 0.0005 µg/mL and 69.72 ± 0.001 µg/mL while IC50 values of acarbose was 5.75 ± 0.007 and 55.29 ± 0.0005 µg/mL respectively. This result is higher in comparison to other previous study. The enzyme kinetics study revealed that bioactive compound was competitive inhibitor for α-amylase and α-glucosidase. In-silico study showed that bioactive compound binds to the binding site of α-amylase, similar to that of acarbose but with higher affinity. The study highlights the importance of endophytic fungi as an alternative source of AGI (α-glucosidase inhibition) to control the diabetic condition in vitro.

Abstract
This review covers the current and emerging analytical methods used in laboratory, field, landscape and regional contexts for measuring soil organic carbon (SOC) sequestration in agricultural soil. Soil depth plays an important role in estimating SOC sequestration. Selecting appropriate sampling design, depth of soil, use of proper analytical methods and base line selection are prerequisites for estimating accurately the soil carbon stocks. Traditional methods of wet digestion and dry combustion (DC) are extensively used for routine laboratory analysis; the latter is considered to be the "gold standard" and superior to the former for routine laboratory analysis. Recent spectroscopic techniques can measure SOC stocks in laboratory and in-situ even up to a deeper depth. Aerial spectroscopy using multispectral and/or hyperspectral sensors located on aircraft, unmanned aerial vehicles (UAVs) or satellite platforms can measure surface soil organic carbon. Although these techniques' current precision is low, the next generation hyperspectral sensor with improved signal noise ratio will further improve the accuracy of prediction. At the ecosystem level, carbon balance can be estimated directly using the eddy-covariance approach and indirectly by employing agricultural life cycle analysis (LCA). These methods have tremendous potential for estimating SOC. Irrespective of old or new approaches, depending on the resources and research needed, they occupy a unique place in soil carbon and climate research. This paper highlights the overview, potential limitations of various scale-dependent techniques for measuring SOC sequestration in agricultural soil.

Abstract
Photosynthetically active radiation (PAR) is one of the most important environmental factors that determine the productivity and grain quality of the crops. Continuous rainy days or cloudy weather throughout crop growth especially at critical stages often resulted in great loss of grain quality and yield in rice. Low light stress has rigorously constrained the rice production in various rice-growing regions, especially in Southeast Asia. Method and time of planting are the major management factors contributing to the higher yield potential of rice by influencing light harvesting and use efficiency. Present study was executed consecutively for 5 years (kharif seasons of 2012-2016) to determine whether planting time improves the radiation absorption and use efficiency in different duration rice cultivars. We evaluated the difference in plant growth and development leading to yield formation under different planting time which related to radiation incidence and interception. The results of the study revealed that PAR interception depends on morphological characters of cultivars and also with agronomic management such as transplanting time and method. Long duration cultivar intercepted more PAR but interception decreased due to late planting (3rd week of July), whereas short duration cultivars (Naveen) when planted earlier (1st week of June) could not effectively utilize intercepted PAR constraining the biomass accumulation and yield formation. Effect of planting density and crop architecture on PAR absorption was apparent among establishment methods as light interception at crop canopy was highest in the system of rice intensification and lowest in that of wet direct seeding. In general, Pooja as a long duration cultivar intercepted more PAR per day but when compared on same date of planting, the comparative absorption of radiation was 30.6% higher in Naveen. The lower yields in the wet season are attributed mostly to reduction in grain number per panicle or per unit land area, which is a consequence of high spikelet sterility. Grain yield of rice planted in July third week was reduced by 3.8, 12.3, and 6.9% over June first and third week and July first week, respectively, mainly due to spikelet sterility (26%) and lower grains per panicle (18%). Our results indicated that agronomic management like optimum time of sowing, cultivar duration, and establishment methods should be followed for yield improvement in tropical lowlands where light intensity is limiting due to prevailing weather situations.

Abstract
Background: Alternate splicing (AS) is a regulatory process during gene expression that allows a single gene to code multiple proteins. Sequencing of RNA (RNA-Seq) is a high throughput technology, which has been used in various studies to identify AS mechanisms in head and neck cancer (HNC). Until date, there is no available review that could update us with the major outcomes from these studies. Aim: To perform a comprehensive literature search for AS studies on HNC via RNA-Seq. Methods: A systematic literature search was performed following PRISMA guidelines to give a complete picture of AS in HNC identified through RNA-Seq. In addition, comprehensive search was also performed to identify the bioinformatics softwares that analyses RNA-Seq data for finding AS in cancer. Results: Six studies were found that used RNA-Seq data for identifying AS events in HNC. Five softwares were used by these studies to identify AS events, of which Suppa and AltAnalyze can also categorize all four AS events to subtypes, i.e., cassette exon skipping (ES), intron retention (IR), mutually exclusive exon (MXE), and alternative 5′ and 3′ splice site (ASS). Additionally, SplAdder, ASprofile, JuncBASE, and MATS softwares have been used to identify and categorize AS events in cancers other than HNC. Conclusion: Alternate splicing in HNC is a complex regulatory process of gene expression. It can be studied through RNA-Seq using various bioinformatics softwares. SplAdder, ASprofile, JuncBASE, and MATS have been used to identify and characterize other cancers, but not implemented in HNC, and hence could be used for studying AS in HNC.

Abstract
Hepatitis C virus (HCV) genotype 4 (GT4) is genetically diverse with 17 confirmed and 4 provisional subtypes. In this report, HCV GT4-infected patient samples from Phase 2/3 clinical studies were analysed to characterize global demographics and genetic diversity of GT4 infection among patients treated with ombitasvir (OBV, NS5A inhibitor) plus paritaprevir/r (NS3/4A inhibitor codosed with ritonavir). Among 17 subtypes isolated from GT4-infected patients in the PEARL-I and AGATE-I studies, subtype prevalence by country of enrolment and country of origin suggested that subtypes 4a and 4d were likely circulating in Europe, while heterogeneous GT4 subtypes and a portion of GT4a detected in European and North American countries were likely due to immigration of HCV-infected patients from Africa. The distributions of birth cohort and race were also significantly different across GT4 subtypes 4a, 4d, and non-4a/4d. In addition, phylogenetic analyses of NS5A sequences revealed clustering within subtype 4a which segregated by the patient-reported country of origin and the presence of the L30R/S polymorphism. HCV NS5A sequences derived from GT4a-infected patients who originated from Europe and the United States clustered separately from sequences derived from patients who originated from Egypt, suggesting that genetically distinct strains of subtype 4a may be circulating globally. Finally, NS5A baseline polymorphisms were frequently detected at amino acid positions of interest for the inhibitor-class and OBV retained activity against 37 of 39 NS5A GT4 clinical isolates, with no impact on treatment outcome in the PEARL-I and AGATE-I studies.

Abstract
This study aims to highlight the importance of screening all HIV positive women for various reproductive tract infections/sexually transmitted infections (RTIs/STIs) irrespective of symptoms and to determine its occurrence in asymptomatic HIV positive women. Relevant specimens were collected for diagnosis of various RTIs/STIs. STIs were diagnosed in nearly one-third of the HIV positive asymptomatic patients which is quite high. The national strategy for STIs/RTIs control misses out large number of asymptomatic RTIs/STIs in HIV positive women which is responsible for silently transmitting these infections in the community. So this strategy should be modified to include screening of all HIV positives women irrespective of symptoms of STIs/RTIs.

Abstract
Diagnosis of drug resistance tuberculosis (TB) by the gold standard method is labour intensive and time consuming. Hence, there is an urgent need for introduction of rapid diagnostic techniques. Line probe assay (LPA) and cartridge-based nucleic acid amplification test (CBNAAT) have been introduced in India under Revised National Tuberculosis Control Program. Spot and morning sputum samples of previously treated patients by anti-TB drugs were subjected to LPA or CBNAAT. Total 682/1253 (54.4%) were diagnosed as rifampicin-resistant. The patients could be diagnosed early by molecular methods and put on second line treatment.

Abstract
Thermal power stations apart from being source of energy supply are causing soil pollution leading to its degradation in fertility and contamination. Fine particle and trace element emissions from energy production in coal-fired thermal power plants are associated with significant adverse effects on human, animal, and soil health. Contamination of soil with cadmium, nickel, copper, lead, arsenic, chromium, and zinc can be a primary route of human exposure to these potentially toxic elements. The environmental evaluation of surrounding soil of thermal power plants in Odisha may serve a model study to get the insight into hazards they are causing. The study investigates the impact of fly ash-fugitive dust (FAFD) deposition from coal-fired thermal power plant emissions on soil properties including trace element concentration, pH, and soil enzymatic activities. Higher FAFD deposition was found in the close proximity of power plants, which led to high pH and greater accumulation of heavy metals. Among the three power plants, in the vicinity of NALCO, higher concentrations of soil organic carbon and nitrogen was observed whereas, higher phosphorus content was recorded in the proximity of NTPC. Multivariate statistical analysis of different variables and their association indicated that FAFD deposition and soil properties were influenced by the source of emissions and distance from source of emission. Pollution in soil profiles and high risk areas were detected and visualized using surface maps based on Kriging interpolation. The concentrations of chromium and arsenic were higher in the soil where FAFD deposition was more. Observance of relatively high concentration of heavy metals like cadmium, lead, nickel, and arsenic and a low concentration of enzymatic activity in proximity to the emission source indicated a possible link with anthropogenic emissions.

Abstract
OBJECTIVE Elderly populations are vulnerable to age-related cognitive decline. Planning, a frontal lobe function, is reported to be affected in the elderly population. There is a paucity of studies which assessed planning skills in the elderly Indian population. The present study aimed to examine the utility of the classic Tower of Hanoi in the assessment of planning skills of elderly Indian subjects. METHODS A total of 215 (60 of whom were females, all aged 55-80 years) cognitively normal elders and 24 patients with mild Alzheimer's disease were recruited. All subjects provided informed consent and their planning skills were assessed using the classic Tower of Hanoi. Performance at each level was measured by the total time taken to solve, number of moves to solve, and the number of rule violations. Receiver operating characteristic curve analysis was exploratively performed to test the utility of the Tower of Hanoi in differentiating patients with mild Alzheimer's disease from those who were cognitively normal. RESULTS Performance measures of cognitively normal group steeply worsened with increasing complexity. With receiver operating characteristic curve analysis, patients with mild Alzheimer's disease were poorly differentiated from cognitively normal group according to their Tower of Hanoi performance. CONCLUSION The Tower of Hanoi test is of limited value for the assessment of planning skills in the Indian elderly population. There is a need to modify and develop a suitable neuropsychology tool to assess the planning skills of elderly Indian subjects and further validate it.

Abstract
OBJECTIVE The primary objective of this study was to examine neurological soft signs in patients with obsessive-compulsive disorder compared with patients with schizophrenia and a control group in the Indian setting. The secondary objective was to find any correlation between age at onset and neurological soft signs scores, as well as that between severity of obsessive-compulsive disorder symptoms (total Yale-Brown Obsessive Compulsive Scale score) and neurological soft signs scores. METHODS This was a cross-sectional hospital-based study of 135 individuals (45 patients with schizophrenia, 45 patients with obsessive-compulsive disorder who were attending the psychiatric outpatient department of Sawai Man Singh Medical College, Jaipur, India, and 45 matched healthy controls) from 20 June 2013 to 22 December 2014. After applying strict inclusion and exclusion criteria, the participants completed the study instruments (Cambridge Neurological Inventory [Part 2] and Yale-Brown Obsessive Compulsive Scale). Their socio-demographic data were also recorded. RESULTS The neurological soft signs total score and domain scores (motor coordination, sensory integration, and disinhibition) were significantly higher in patients with schizophrenia (p < 0.05) than in the obsessive-compulsive disorder group or the control group. The obsessive-compulsive disorder group did not significantly differ from the control group in terms of neurological soft signs scores. No correlation was found between neurological soft signs scores and age at onset as well as that between neurological soft signs scores and total Yale-Brown Obsessive Compulsive Scale score. CONCLUSION Neurological soft signs assessed by the Cambridge Neurological Inventory and Yale-Brown Obsessive Compulsive Scale, which discriminate patients with schizophrenia from controls, appear to be relatively specific to schizophrenia. Further studies are required to explore neurological soft signs in patients with obsessive-compulsive disorder.

Abstract
Integrated rice-fish culture, an age-old farming system, is a technology which could produce rice and fish sustainably at a time by optimizing scarce resource use through complementary use of land and water. An understanding of microbial processes is important for the management of farming systems as soil microbes are the living part of soil organic matter and play critical roles in soil C and N cycling and ecosystem functioning of farming system. Rice-based integrated farming system model for small and marginal farmers was established in 2001 at Central Rice Research Institute, Cuttack, Odisha. The different enterprises of farming system were rice-fish, fish-fingerlings, fruits, vegetables, rice-fish refuge, and agroforestry. This study was conducted with the objective to assess the soil physicochemical properties, microbial population, carbon and nitrogen fractions, soil enzymatic activity, and productivity of different enterprises. The effect of enterprises induced significant changes in the chemical composition and organic matter which in turn influenced the activities of enzymes (urease, acid, and alkaline phosphatase) involved in the C, N, and P cycles. The different enterprises of long-term rice-based farming system caused significant variations in nutrient content of soil, which was higher in rice-fish refuge followed by rice-fish enterprise. Highest microbial populations and enzymatic properties were recorded in rice-fish refuge system because of waterlogging and reduced condition prolonged in this system leading to less decomposition of organic matter. The maximum alkaline phosphatase, urease, and FDA were observed in rice-fish enterprise. However, highest acid phosphatase and dehydrogenase activity were obtained in vegetable enterprise and fish-fingerlings enterprise, respectively.

Abstract
Fly ash (FA), a byproduct of coal combustion in thermal power plants, has been considered as a problematic solid waste and its safe disposal is a cause of concern. Several studies proposed that FA can be used as a soil additive; however its effect on microbial response, soil enzymatic activities and heavy metal accumulation in soil and grain of rice (cv. Naveen) to fly ash (FA) application was studied in a pot experiment during dry season 2011 in an Inceptisol. Fly ash was applied at a rate of zero per cent (FS), five per cent (FA5), ten per cent (FA10), twenty per cent (FA20), 40 per cent (FA40) and 100 per cent (FA100) on soil volume basis with nitrogen (N), phosphorus (P) and potassium (K) (40:20:20mg N:P:Kkg(-1) soil) with six replications. Heavy metals contents in soil and plant parts were analysed after harvest of crop. On the other hand, microbial population and soil enzymatic activities were analysed at panicle initiation stage (PI, 65 days after transplanting) of rice. There was no significant change in the concentration of zinc (Zn), iron (Fe), copper (Cu), manganese (Mn), cadmium (Cd) and chromium (Cr) with application of fly ash up to FA10. However, at FA100 there was significant increase of all metals concentration in soil than other treatments. Microorganisms differed in their response to the rate of FA application. Population of both fungi and actinomycetes decreased with the application of fly ash, while aerobic heterotrophic bacterial population did not change significantly up to FA40. On the other hand, total microbial activity measured in terms of Fluorescein diacetate (FDA) assay, and denitrifiers showed an increased trend up to FA40. However, activities of both alkaline and acid phosphatase were decreased with the application of FA. Application of FA at lower levels (ten to twenty per cent on soil volume basis) in soil enhanced micronutrients content, microbial activities and crop yield.

Abstract
Harmine, a beta-carboline alkaloid, is widely distributed in the plants, marine creatures, insects, mammalians as well as in human tissues and body fluids. Harmine was originally isolated from seeds of Peganum harmal in 1847 having a core indole structure and a pyridine ring. Harmine has various types of pharmacological activities such as antimicrobial, antifungal, antitumor, cytotoxic, antiplasmodial, antioxidaant, antimutagenic, antigenotoxic and hallucinogenic properties. It acts on gamma-aminobutyric acid type A and monoamine oxidase A or B receptor, enhances insulin sensitivity and also produces vasorelaxant effect. Harmine prevents bone loss by suppressing osteoclastogenesis. The current review gives an overview on pharmacological activity and analytical techniques of harmine, which may be useful for researcheres to explore the hidden potential of harmine and and will also help in developing new drugs for the treatment of various diseases.

Abstract
Cutaneous T-cell lymphomas (CTCLs) comprise a heterogeneous group of lymphoproliferative disorders characterized by the proliferation of skin-homing post-thymic T-cells. It is the second most common extranodal non-Hodgekin's lymphoma. Many variants of mycosis fungoides and CTCLs are known to date, differing in clinical, histological, and immunophenotypic characteristics. Oral involvement has also been reported rarely in CTCLs. Treatment depends on the disease stage or the type of variant. New insights into the disease and the number of emerging novel therapeutic options have made it an interesting area for dermatologists and medical oncologists.

Abstract
The aim of this study was to evaluate scar thickness in cases of pregnancy with previous caesarean section, by trans-vaginal sonography (TVS) and magnetic resonance imaging (MRI), and to correlate precision of radiologically-measured scar thickness with actual measurement of scar thickness. A total of 35 pregnant patients with previous caesarean section planned for elective caesarean section, were evaluated prospectively. Their scar thickness was measured by TVS and MRI on the day of elective repeat caesarean section. These measurements were correlated with each other and with scar thickness measured during elective repeat caesarean section by using a caliper. The correlation coefficients between scar thickness measured by TVS and MRI with peroperative evaluation with a caliper, were +0.72 and +0.59, respectively. The study concluded that as MRI is a costlier modality and TVS has better correlation coefficient with actual scar thickness, TVS can be considered to be the better modality for antenatal scar thickness measurement.
