Abstract
Temporomandibular joint (TMJ) ankylosis and oral submucous fibrosis (OSMF) often exhibit elongated hyperplastic coronoid processes with fibrous attachments to the temporalis muscle. In managing this condition, a vital step involves performing a coronoidotomy or coronoidectomy alongside the primary surgical procedure. While coronoidectomy is preferable due to reattachment issues, its complexity arises from the thickened and elongated coronoid process. Our technical note introduces a screw and wire assisted coronoidectomy method, found to be efficient, replicable, and time-saving.

Abstract
Carbon foot prints (CFs) studies based on life cycle assessment between sheep farming systems and green house gases (GHG) emissions is one of the best indicators to quantify the amount of GHG emissions per kg of product. Therefore, a life cycle assessment (LCA) study was conducted for three different sheep farming systems i.e. intensive system (stall fed only), semi-intensive (grazing with supplementation) and extensive system (grazing only) under semiarid region of India to assess the carbon cost of sheep rearing. The total CFs were estimated to be 16.9, 15.8 and 17.1 kg CO2-eq in intensive, semi-intensive and extensive system of grazing indicating semi-intensive system to be most carbon (C) efficient. For 1kg mutton production in semi-intensive and intensive system, around 30% and 24% CFs were contributed from enteric fermentation and feed respectively, whereas, in extensive system, the contribution of enteric fermentation increased up to 50%. The carbon foot prints analysis gives an insight of carbon inputs used but the amount of CO2 sequestered in soil making LCA a holistic approach for estimating GHG emissions from livestock.

Abstract
The choices for managing a condylar head fracture (CHF) of the mandible are either open surgical or closed functional treatments (CFT) and the decision depends on various factors. The purpose of this systematic review was to ascertain from the available literature whether the open method or CFT yields better outcomes in managing CHF. We have systematically reviewed published articles according to the PRISMA statement. The search was conducted in PubMed, Google Scholar, Semantic Scholar, and the Cochrane Library database for comparative studies about both open and closed treatments from inception until April 2023. The outcomes of interest were mouth opening (MO), protrusion, laterotrusion, postoperative pain, and malocclusion. Eight studies met the inclusion criteria. The review comprised of 326 cases, among which 177 were managed by open methods and 149 were treated by CFT. The incidence of postoperative malocclusion and pain were significantly less in the open group. MO was better in the open treatment group although this was not statistically significant. Protrusion and laterotrusion occurred slightly more in CFT, although these were also statistically not significant. Overall, meta-analysis favoured open methods of managing CHF. Although enough evidence exists for the use of open methods for selected condylar head fractures, CFT still demonstrated favourable outcomes in undisplaced fractures. The selection of a particular treatment method should be individualised on the basis of each particular case considering the risk/benefits. Further high quality randomised trials are needed to establish a therapeutic guideline.

Abstract
OBJECTIVE Surgical innovation led to an endoscopic-assisted intraoral approach for managing condyle fractures. The purpose of this systematic review is to purview the role of the endoscope and determine the range of information, summarizing the evidence for the benefit of surgeons on an endoscopic-assisted intraoral approach. STUDY DESIGN A literature search was conducted in PubMed, Google Scholar, Semantic Scholar, and Cochrane Library databases for studies mentioning the endoscopic intraoral approach for managing mandibular condylar fractures. Outcomes include the role of the endoscope, challenges, adjunct armamentarium, duration, and complications associated with the transoral and transbuccal approach for screw fixation. The meta-analysis was conducted with prevalence estimates and standardized means using STATA. RESULTS Thirty-nine studies were included. A 30° angulated, 4-mm-thick endoscope was the most commonly used endoscope. Two mini plates were most commonly used for fixation. Facial nerve weakness was higher in the transbuccal approach (1.24%) than in the transoral approach (0.8%). Pooled analysis (6 studies) showed that the duration of the surgical procedure was less in the transoral approach compared with the transbuccal approach for screw fixation. The bailout was 1.49%. CONCLUSIONS The endoscopic-assisted intraoral approach is reliable for condylar fracture management. The transoral and transbuccal approaches can be used for screw fixation with comparable outcomes.

Abstract
This paper aims to present a rare case report of bilateral pseudoaneurysm secondary to condylar fracture and its management with a brief review of literature. A patient of age 19 years with alleged history of road traffic accident presented 6 weeks lately to our department with slow growing swelling in right preauricular area. History revealed bilateral condylar fracture with right parasymphysis fracture of mandible for which patient underwent maxillomandibular fixation for 4 weeks. The diffuse swelling in preauricular region showed positive signs of pulsation and audible bruit. Ultrasonography and contrast-enhanced computed tomography suggested the bilateral presence of vascular anamoly from the terminal branches of external carotid artery. Diagnostic angiography confirmed presence of pseudoaneurysm at the bifurcation of the internal maxillary artery and superficial temporal artery (STA) on right side whereas on the left side it was at proximal STA. Bilateral endovascular coil and gel foam embolization was done and thrombosis was confirmed with high frequency ultrasound on fourth postintervention day. The swelling completely resolved in a period of 1 month with no evidence of recurrence in the following 2-year follow-up period. Routine investigation revealed presence of pseudoaneurysm on left side which was completely without any clinical signs as repoterd by many cases of condylar fracture in the literature review. Pseudoaneurysm may remain silent and are exposed intraoperatively with massive bleeding which causes significant morbidity. Hence, prompt diagnosis and management is essential to avoid unexpected complication perioperatively.

Abstract
Availability of ample and nutritious fodder for livestock is always a challenge in arid region. Choice of crops such as groundnut that can fulfil the requirement of fodder with its crop residues along with human needs can be a viable option to bridge the gap between availability and requirement of fodder. The fodder yield and quality largely depend on soil moisture and nutrient supply especially sulphur (S), a key nutrient for improving groundnut fodder quality. However, no researchers have given emphasis on coupling effect of drip irrigation (DI) and sulphur on fodder yield, quality, digestibility and water use efficiency (WUE). Therefore, the study was conducted to determine the effects of different regimes of DI and S on productivity and quality of fodder. Results revealed that higher regimes of DI i.e. 0.8 +1.0 PE(pan evaporation) and 1.0 PE level of irrigation along with 40 kg S ha-1 significantly improved the yield, primary quality traits (crude protein, ether extract and ash), digestibility indices and significant reduction in Fibers which indicates improvement in quality of fodder. Fodder productivity was 27.0 and 25.6% higher in 1.0 PE and 0.8+1.0 PE level of irrigation, respectively, as compared to 0.6 PE level (lower water regime) of irrigation, although 0.6 PE level of irrigation recorded higher WUE and was at par with 0.8 PE and 0.6 +1.0 PE level of DI. By changing the levels of DI from 1.0 PE to 0.8+1.0 PE, considerable water can be saved without affecting the yield and quality of fodder. Similarly, crop responded to S up to 60 kg ha-1 but at par with 40 kg S ha-1 indicating that application of extra S after 40 kg did not warrant any extra benefit in terms of fodder yield, WUE and quality of fodder. Thus, adjusting the PE levels of DI for water saving and optimal S application can be a sustainable strategy to improve the productivity and quality of groundnut fodder in arid region.

Abstract
Iodoform formulations are used as packing material following the surgical removal of jaw lesions. The purpose of this review was to explore the evidence and efficacy of iodoform-based dressings. We have systematically reviewed published articles according to the PRISMA statement. The search was conducted in PubMed, Google Scholar, Semantic Scholar, and the Cochrane Library database for articles mentioning the use of iodoform as dressing material for jaw lesions from January 2000 to March 2022. Finally, 92 studies were included. A total of 386 patients whose ages ranged from five months to 86 years (male n = 180, female n = 117). Different formulations of iodoform used were BIPP (n = 67), Whitehead's varnish (n = 17), iodoform (n = 7) and, iodine (n = 1) for its antiseptic properties. An iodoform impregnated gauze pack was changed once a week, most commonly, for a stipulated duration, until complete healing of the cavity. In the present review, iodoform was used, most commonly, in pathological cavities following surgical treatment of ameloblastoma and odontogenic keratocyst. Toxicity was reported in two studies. Based on the current review, iodoform is relatively safe and can be used in the management of extensive jaw lesions in which secondary healing is expected. Prospective and randomised control trials are recommended to assess the efficacy of various formulations and to delineate the timeframe for patient compliance.

Abstract
A blockage or cessation of blood flow to our heart muscle is a sign of Coronary Heart Disease (CHD), which is caused by an accumulation of fatty substances in the coronary arteries known as atheroma. The principal blood channels that deliver blood to the heart are known as coronary arteries. In this paper, the possible application of deep learning technique is explored for the detection of Coronary Heart Disease. In this study, the methodology includes infrastructure creation for the detection of CHD using supervised and unsupervised learning. The result shows the proceeding to manage the data set and process the data there, user input is appropriately gathered. The embedded system that conducts data translation is linked to the controller sensor, which regulates the CHD pulse system. The study concludes that the diagnostic accuracy of the deep learning model using Decision Tree (DT) and Naive Bayes (NB) Classification is effective and error-free. DT and NB Classification is an effective way of detecting CHD by the deep learning model. The future potential of this paper is the development of models for heart disease diagnoses in patients around the world.

Abstract
Central granular cell odontogenic tumor (CGCOT) is sporadic benign odontogenic tumor and it especially occurs in women older than 50 years of age. Radiologically it manifests as unilocular to the multilocular radiolucency with sometimes mixed densities. Histopathology displays sheets and islands of large eosinophilic cells with abundant granular cytoplasm, however few cases exhibit inadequate epithelium, thus creating a diagnostic confusion. Though, resection is advocated by some surgeons, however because of the non-aggressive biological behaviour, enucleation or curettage is the treatment of choice for this lesion. Till now only 39 cases have been reported in the past six decades. We are reporting the first case of CGCOT occurring in the youngest age of eleven-year-old patient with massive size of 11 × 7 × 6 cm. This would add CGCOT as a differential diagnosis in the bony lesions of younger individuals. In addition, the importance of immunohistochemistry studies in cases with scarce odontogenic epithelium and the potential role of Carnoy's solution in the management of this rare tumor in this age group was emphasized.

Abstract
OBJECTIVE The recent trend favors the open reduction and internal fixation of condylar fractures to prevent long-term consequences. Nonendoscopic intraoral approach is an option for management without a visible scar. The purpose of this systematic review was to explore the evidence, armamentarium, methods of reduction and fixation, challenges, and complications. STUDY DESIGN We have systematically reviewed published articles on the intraoral approach for condylar fracture management following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The search was conducted in PubMed, Google Scholar, Semantic Scholar, and Cochrane library database, to find relevant articles from January 1980 to March 2022. Descriptive statistics were applied to obtain the results. RESULTS Finally, 23 studies were included. The incision described for the intraoral approach was similar to sagittal split osteotomy in all studies. A wide array of specialized instruments, methods, and challenges has been outlined for visualization, reduction, and fixation. The incidence of complications in the entire review was 23% (72/306). CONCLUSION The challenges encountered in the nonendoscopic intraoral approach for condylar fracture management can be negated with the use of specialized instruments and with experience. However, further research is warranted for a specialized set of miniature instruments to ease the procedure, make it time-efficient and optimize hardware selection.

Abstract
Globally, 10-20% of horticultural wastes are disposed in landfills leading to environmental pollution. Recycling these wastes as animal feedstuff will lessen food-feed competition and minimize environmental hazards. The present study was undertaken to determine the nutritional quality of fresh fruit and vegetable waste (F&VW) and their dietary inclusion on nutrient utilization, antioxidant status, greenhouse gases (GHG) emissions and potable water sparing efficacy in sheep. Three dietary combinations were formulated i.e. control (C):70% Cenchrus ciliaris hay +30% concentrate mixture (CM), diet with fruit waste (FWD):70% Cenchrus ciliaris hay +20% CM +10% FW and diet with vegetable waste (VWD):70% Cenchrus ciliaris hay +20% CM +10% VW for in vitro and in vivo evaluation of these wastes as potential livestock feed. Twenty-one adult ewes were allocated into 3 groups C, FWD and VWD and fed on the above three diets. Dry matter and crude protein digestibility were significantly enhanced by 5.5 and 7.2%; 7.3 and 7.6% in F&VW supplemented groups, respectively, without affecting feed intake. Plasma total antioxidant capacity (TAC) was improved by 32.2 and 26.3% in F&VW supplemented groups. Inclusion of F&VW biomass reduced annual methane (CH4) and nitrous oxide (N2O) emissions (kg CO2eq/sheep) by 3.12 and 4.55%; 15.18 and 14.92% and thus contributed to lowering of global warming potential by 4.00 and 5.27%, respectively. Furthermore, there was a net reduction of potable water consumption by 21.78 and 13.92% in F&VW supplemented groups, respectively. Therefore, it can be concluded that F&VW can be a potential feedstuff for ruminants and its efficient reuse would minimize environmental impacts associated with disposal of such waste in the landfills.

Abstract
Long standing adult temporomandibular joint ankylosis (TMJA) results in smaller ramal height, and warped and undulated ramus. Despite the efforts made to standardise the sizes available in stock joint (Zimmer Biomet®), the system causes fit challenges in TMJA patients. The aim of the study was to evaluate the virtual feasibility of stock prostheses in TMJA patients. The data included amount of bone contouring for fossa placement, available ramal length, length discrepancy if placed straight, angulation of mandibular component required to adapt to the bone, and mediolateral fit discrepancy. CT data of 50 TMJA patients (71 joints; unilateral, n=29; bilateral, n=21; male, n=33; female, n=17) with mean age of 24.26±8.88 years were included. 53 joints required more than 3mm lateral bone reduction for fossa placement. The ramal length were categorised into ranges 35-40mm (n=15), 41-45mm (n=14), 46-50mm (n=28) and >50mm (n=14). Correlation between the age of occurrence of ankylosis and ramal length using the Pearson correlation coefficient revealed a positive correlation (r=0.38, p=0.001). Length discrepancy, angulation of mandibular component, and mediolateral fit discrepancy decreases as the ramal length increases. Only 14 joints had appropriate fit of stock prostheses while the remaining 57 joints warranted compromised placement. Even the smallest available stock mandibular component (45mm) had a compromised fit in terms of length and adaptability on the lateral aspect of ramus. The study concludes that a short ramus is mostly limiting factor in using stock prosthesis in TMJA patients. There is a need for still smaller size stock prostheses.

Abstract
Comminuted mandibular fracture poses a surgical challenge. Extensive comminution and absence of reference adds complexity particularly in anterior region. In this technical note, we describe a novel application of virtual surgical planning combined with 3D printing which grants precise anatomic reduction in such cases. Computed Tomography data (mandible) of another patient of same age and sex was utilized to create reference model by virtual surgical planning. Virtually created model was 3D printed and utilized for precontouring the reconstruction plate which assisted in achieving satisfactory outcome.

Abstract
Wool is a biodegradable fiber, rich in nutrients and can be recycled in soil as a fertilizer for maximum benefits. The present study was planned with the hypothesis that waste wool could be used as a nutrient source or manure to forage crops and aim of this study was to identify practicable recycling options of sheep based wastes in agriculture. In our study, we have compared the effect of different sheep based organic wastes on soil health, crop productivity and water use. Application of waste wool in soil significantly improved the fertility status of soil, and considerable improvement was also observed in organic carbon and nitrogen, i.e. around 30.8 and 32.6% higher over control. The activities of soil enzymes were 10-30% and 3-20% higher in waste wool treatment as compared to control and sheep based manures, respectively. Application of waste wool not only improved soil health but produced 50% higher grain and dry fodder yield of barley over control. The improvement in physical properties of soil with waste wool resulted in higher water use efficiency of the system. Our study will help in distinguishing choices for safe use of organic wastes along with up gradation of soil health and crop water utilization, particularly in nutrient poor soils of arid and semi-arid region of India.

Abstract
Cranioplasty is a common neurosurgical procedure which makes use of autologous bone or alloplastic material for cranial defect reconstruction. Alloplastic reconstruction is routinely done in cases where viable autologous bone is not available due to various reasons. Hydroxyapatite implants, patient-specific titanium and PEEK are widely employed materials due to their biocompatibility, durability, and high adaptation accuracy. However, their high cost and limited availability make them a less viable option for the common man. Polymethyl methacrylate (PMMA) is one of the commonly used alloplastic material for cranioplasty. This note presents a novel, economic, patient-specific, 3D printing-assisted and heat polymerized PMMA cranioplast fabrication technique with an accuracy comparable to that of patient-specific titanium and PEEK cranioplast.

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
Toxicity of the effluent generated at the Rajrappa coal mine complex under the Central Coalfields Limited (CCL, a subsidiary of Coal India Limited) in Jharkhand, India was investigated. The concentrations (mg L-1) of all the toxic metals (Fe, Mn, Ni, Zn, Cu, Pb, Cr, and Cd) in the coal mine effluent were above the safe limit suggested by the Environmental Protection Agency (EPA 2003). Among these, Fe showed the highest concentration (18.21 ± 3.865), while Cr had the lowest effluent concentration (0.15 ± 0.014). Efforts were also made to detoxify the effluent using two species of aquatic macrophytes namely "'Salvinia molesta and Pistia stratiotes." After 10 days of phytoremediation, S. molesta removed Pb (96.96%) > Ni (97.01%) > Cu (96.77%) > Zn (96.38%) > Mn (96.22%) > Fe (94.12%) > Cr (92.85%) > Cd (80.99%), and P. stratiotes removed Pb (96.21%) > Fe (94.34%) > Ni (92.53%) > Mn (85.24%) > Zn (79.51%) > Cr (78.57%) > Cu (74.19%) > Cd (72.72%). The impact of coal mine exposure on chlorophyll content showed a significant decrease of 42.49% and 24.54% from control values in S. molesta and P. stratiotes, respectively, perhaps due to the damage inflicted by the toxic metals, leading to the decay of plant tissues.

Abstract
Biochemical pathways of methanogenesis and methanotrophy coupled with carbon (C)-nitrogen (N) metabolism were studied in long term (13years) manured systems in lowland rice paddy through metagenomics approach. Manured systems included in this study were, control (exclusion of application of any manure), farm yard manure (FYM, @5Mgha-1yr-1) and green manuring (GM with Sesbania aculeata). Metagenomic sequence data revealed the dominance of C decomposing bacterial communities' like Proteobacteria, Planctomycetes, Actinobacteria, Firmicutes, Acidobacteria, in manure amended soils as compared to control. Diversities for assimilatory and dissimilatory N-fixing microorganisms at phylum level were found higher under GM as compared to rest. Two genera responsible for methanogenesis, viz. Methanolobus and Methanotorris were absent in manured systems as compared to control. The acetoclastic and serine pathway was found as the predominant pathway for methanogenesis and methanotrophy, respectively, in tropical lowland rice paddy. Abundance reads of enzymes were in the range of 254-445 in the acetoclastic methanogenesis pathway. On the other hand, these were varied from 165 to 216 in serine pathway of methanotrophy. Lowland paddy soil exhibited higher functional and structural diversities in manured systems as compared to unamended control in respect to labile C pools and CH4 production. Methane (CH4) emission was 31% higher in FYM system than GM. However, nitrous oxide (N2O) emission was found 25% higher in GM as compared to FYM. As a whole, bacterial diversities were higher under FYM system in tropical lowland rice paddy as compared to GM and unamended systems.

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
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
Cancer stem-like cells represent poorly differentiated multipotent tumor-propagating cells that contribute disproportionately to therapeutic resistance and tumor recurrence. Transcriptional mechanisms that control the phenotypic conversion of tumor cells lacking tumor-propagating potential to tumor-propagating stem-like cells remain obscure. Here we show that the reprogramming transcription factors Oct4 and Sox2 induce glioblastoma cells to become stem-like and tumor-propagating via a mechanism involving direct DNA methyl transferase (DNMT) promoter transactivation, resulting in global DNA methylation- and DNMT-dependent downregulation of multiple microRNAs (miRNAs). We show that one such downregulated miRNA, miRNA-148a, inhibits glioblastoma cell stem-like properties and tumor-propagating potential. This study identifies a novel and targetable molecular circuit by which glioma cell stemness and tumor-propagating capacity are regulated.

Abstract
An experiment was conducted to assess the effect of fly ash deposition without and with (0.25, 0.50, 1.0 and 1.5 g m(-2 )day(-1)) foliar dusting on the photosynthesis, stomatal conductance, transpiration, leaf temperature, albedo and productivity of rice. Dusting of 0.5 g m(-2 )day(-1) fly ash and above significantly reduced the photosynthesis, stomatal conductance, transpiration and albedo. Panicle initiation and flowering stages were more influenced by the fly ash deposition as compared to active tillering stage. At higher rates of fly ash deposition, all growth and yield parameters were significantly influenced due to increased heat load and reduced intercellular CO2 concentration. A significant reduction of 12.3, 15.7 and 20.2 % in grain yield was recorded over control when fly ash was dusted at 0.5, 1.0 and 1.5 g m(-2 )day(-1), respectively.

Abstract
Fish testis is equipped with different isoforms of nitric oxide synthase (NOSs) and is capable of producing nitric oxide (NO). Cellular sources of NO in the catfish testis are germ cells, Leydig cells, and macrophages. Production of testicular NO is under endocrine inhibitory control. Expression of NOSs exhibits seasonality and that depends on the reproductive status of fish. Leydig cells are highly sensitive to chemical as well as biological NO. NO inhibits testosterone production by the testis in vivo as well as by the isolated Leydig cells in vitro.

Abstract
The present work describes a simple, precise and accurate HPLC method for estimation of montelukast sodium in bulk and in tablet dosage form. The separation was achieved by using octadecylsilane column (C18) and acetonitrile:1 mM sodium acetate adjusted to pH 6.3 with acetic acid in proportion of 90:10 v/v as mobile phase, at a flow rate of 1.5 ml/min. Detection was carried out at 285 nm. The retention time of montelukast sodium was found to be 3.4 min. The limit of detection was found 1.31 µg/ml and limit of quantification 3.97 µg/ml. The accuracy and reliability of the proposed method was ascertained by evaluating various validation parameters like linearity (1-100 µg/ml), precision, accuracy and specificity according to ICH guidelines. The proposed method provides an accurate and precise quality control tool for routine analysis of montelukast sodium in bulk and in tablet dosage form.

Abstract
Effect of growth hormone (GH), injected either at the morning or evening, on the somatic and ovarian development of the Asian catfish, Clarias batrachus was studied during the late quiescence and early recrudescence phase of the reproductive cycle. GH treatment during the late quiescence phase (December-January; 11L: 13D, average water temperature 16.2+/-1 degrees C) failed to exert any impact on the somatic or ovarian development, except that it increased plasma testosterone marginally, and decreased hepatic level of triglycerides (TG); while during the early recrudescence phase (March-April; 12.4L: 11.20D; average water temperature-28.4+/-2 degrees C), GH had significant circadian time-dependent effect on somatic and ovarian development. GH injection at morning stimulated ovarian growth and development, as was evident from the dose-dependent significant increase in ovarian weight, gonadosomatic index, plasma levels of testosterone and estradiol-17beta following GH treatment. The ovarian morphology also revealed the advancement in follicular development in GH treated fish. GH also induced remarkable increase in ovarian levels of TG, free cholesterol (CF) and phospholipids (PL) with concomitant declines in their hepatic levels. However, evening hour GH injection provoked appreciable increase in body weight without having any significant impact on ovarian weight and GSI. Few oocytes in the ovary of evening hour GH treated fish exhibited advanced stages of development, but number of such advanced stage oocytes was significantly much less than the morning hour GH injected fish. Ovarian TG and PL remained unchanged, while their hepatic levels were increased. The temporal synergism between GH and other intrinsic factors regulating body growth and gonadal development may be suggested herewith to be considered prior to administration of GH in fishes. This study has immense practical use in aquaculture.

Abstract
AIM To compare few phenotypic and genotypic characteristics of two desulfurizing bacterial strains, Mycobacterium phlei SM120-1 and Mycobacterium phlei GTIS10. METHODS AND RESULTS In the present study, dibenzothiophene (DBT) desulfurizing activity, composition of fatty acids of cell membranes, DBT sulfone monoxygenase gene (bdsA) and the selection pressure applied during the growth and enrichment of the bacterial strains M. phlei SM120-1 and M. phlei GTIS10 were compared in our laboratory. The DBT desulfurization activity of M. phlei SM120-1 was found to be 0.17 +/- 0.02 micromol 2-HBP min(-1) (gram dry cell weight)(-1) and that of the bacterial strain M. phlei GTIS10 was 1.09 +/- 0.05 micromol 2-HBP min(-1) (gram dry cell weight)(-1). Fatty acid methyl ester analysis of cell membranes of these two bacterial strains in the presence of light gas oil showed that both the strains had different fatty acid profiles in their cell membranes. Comparison of the full gene sequences of the desulfurization gene bdsA in the two bacterial strains showed significant difference in the bdsA gene sequences. There was a significant difference observed in the selection pressure applied during the growth and enrichment of the two bacterial strains. CONCLUSIONS The results of the comparative study of the bacterial strains, M. phlei SM120-1 and M. phlei GTIS10 showed that there were considerable differences in the phenotypic and genotypic characteristics of these two strains. SIGNIFICANCE AND IMPACT OF STUDY The present study would broaden the understanding of biodesulfurization trait at intra-species level.
