Abstract
BACKGROUND The goal of this work was to synthesize and fabricate matrix type transdermal patches based on a combination of polymers (Eudragit L100, HPMC and PVP K30), plasticizer and crosslinking agents (propylene glycol and triethyl citrate) and adhesives (Dura Tak 87-6908) to increase Thiocolchicoside (THC) absorption via topical route. This method allows avoidance of first-pass metabolism along with a consistent and extended duration of therapeutic activity. METHODS Fabrication and casting of polymeric solutions containing THC was done either in petri plates or through lab coater to get transdermal patches. Finally, the formulated patches were studied for their physicochemical and biological evaluation using scanning electron microscopy, FTIR, DSC, XRD and ex-vivo permeation studies using pig ear skin. RESULTS FTIR studies confirm that the THC characteristics peaks (carbonyl (Amide I) at 1525.5 cm-1, C=O stretching (tropane ring) at 1664.4 cm-1, Amide II band (N-H stretching) at 3325.9cm-1, thioether band at 2360.7cm-1, and OH group stretching band at 3400.2 cm-1) are still present in the polymer mixture even after formulation as a transdermal patch, indicating compatibility among all excipients. While on the other hand, DSC studies confirm endothermic peaks for all the polymers along with THC with the highest enthalpy of 65.979 J/g, which is an indicator of sharp endothermic peak at 198℃, leading to the melting of THC. The percentage drug content and percentage moisture uptake of all the formulation was found in the range of 96±2.04 to 98.56±1.34% and 4.13±1.16 to 8.23±0.90%, respectively. Drug release and release kinetics studies confirm that it is dependent on the composition of individual formulation. CONCLUSION All these findings support the possibility of using suitable polymeric composition, as well as proper formulation and manufacturing circumstances, to create a one-of-a-kind technology platform for transdermal drug administration.

Abstract
Introduction Cell line derived from fish has been established as a promising tool for studying many key issues of aquaculture covering fish growth, disease, reproduction, genetics, and biotechnology. In addition, fish cell lines are very useful in vitro models for toxicological, pathological, and immunological studies. The easier maintenance of fish cell lines in flexible temperature regimes and hypoxic conditions make them preferable in vitro tools over mammalian cell lines. Great excitement has been observed in establishing and characterizing new fish cell lines representing diverse fish species and tissue types. The well-characterized and authenticated cell lines are of utmost essential as these represent cellular functions very similar to in vivo state of an organism otherwise it would affect the reproducibility of scientific research. Conclusion The fish cell lines have exhibited encouraging results in several key aspects of in vitro research in aquaculture including virology, nutrition and metabolism, production of vaccines, and transgenic fish production. The review paper reports the cell lines developed from fish, their characterization, and biobanking along with their potential applications and challenges in in vitro research.

Abstract
We report the simulation of high-efficiency c-silicon Passivated Emitter Rear Contact (PERC) type solar cell structure with rear side passivated with HfO₂ as a passivating material. Variation in the half length of pyramid has been carried out to investigate its effect on the solar cell electrical characteristics such as fill factor (FF), open circuit voltage (Voc) and efficiency. Aluminum back Surface Field (Al-BSF) and PERC type solar cell with Al₂O₃ passivation layer structures were also modeled for comparison. Effect of variation in passivation layer (HfO₂) thickness (10 and 15 nm) and permittivity (k = 14 and 25) on the solar cell electrical characteristics has been investigated. Result shows the efficiency improvement in the PERC solar cell with HfO₂ passivation layer by 0.5941% and 0.983% as compared to the Al-BSF and PERC with Al₂O₃ passivation layer at 8 μm pyramid half length. Increased series resistance and reduced FF has been observed with the incorporation of passivation layer at the solar cell structure. Negligible effect of passivation layer thickness has been observed on the solar cell electrical parameters whereas the permittivity value does have significant effect.

Abstract
Burn is the immense public health issue globally. Low and middle income countries face extensive deaths owing to burn injuries. Availability of conventional therapies for burns has always been painful for patients as well as expensive for our health system. Pharmaceutical experts are still searching reliable, cheap, safe and effective treatment options for burn injuries. Fusidic acid is an antibiotic of choice for the management of burns. However, fusidic acid is encountering several pharmaceutical and clinical challenges like poor skin permeability and growing drug resistance against burn wound microbes like Methicillin resistant Staphylococcus aureus (MRSA). Therefore, an effort has been made to present a concise review about molecular pathway followed by fusidic acid in the treatment of burn wound infection in addition to associated pros and cons. Furthermore, we have also summarized chitosan and phospholipid based topical dermal delivery systems customized by our team for the delivery of fusidic acid in burn wound infections on case-to-case basis. However, every coin has two sides. We recommend the integration of in-silico docking techniques with natural biomacromolecules while designing stable, patient friendly and cost effective topical drug delivery systems of fusidic acid for the management of burn wound infection as future opportunities.

Abstract
AIMS The impact of municipal waste on pathogenic micro-organisms released into the environment is a public health concern. This study aims to evaluate the effects of sewage sludge and antibiotic contaminants on stress response, virulence and antibiotic resistance in a pathogenic Escherichia coli. METHODS AND RESULTS The effects of sewage sludge leachates on uropathogenic E. coli CFT073 were determined by monitoring the expression of 45 genes associated with antibiotic/metal resistance, stress response and virulence using RT-qPCR. The E. coli gene expression was validated using subinhibitory concentrations of tetracycline and ciprofloxacin. E. coli exposed to sewage sludge or sewage sludge+fly ash leachates altered the expression of five antibiotic and metal resistance, three stress response and two virulence-associated genes. When antibiotics were combined with sludge or sludge+fly ash the antibiotic-associated gene expression was altered. CONCLUSIONS E. coli treated with two sludge leachates had distinct gene expression patterns that were altered when the sludge leachates were combined with tetracycline, although to a lesser extent with ciprofloxacin. SIGNIFICANCE AND IMPACT OF THE STUDY The E. coli multigene expression analysis is a potential new tool for assessing the effects of pollutants on pathogenic microbes in environmental waters for improved risk assessment.

Abstract
Antibiotic resistance is a global problem and there is an urgent need to augment the arsenal against pathogenic bacteria. The emergence of different drug resistant bacteria is threatening human lives to be pushed towards the pre-antibiotic era. Botanical sources remain a vital source of diverse organic molecules that possess antibacterial property as well as augment existing antibacterial molecules. Piper betle, a climber, is widely used in south and south-east Asia whose leaves and nuts are consumed regularly. Hydroxychavicol (HC) isolated from Piper betle has been reported to possess antibacterial activity. It is currently not clear how the antibacterial activity of HC is manifested. In this investigation we show HC generates superoxide in E. coli cells. Antioxidants protected E. coli against HC induced cell death while gshA mutant was more sensitive to HC than wild type. DNA damage repair deficient mutants are hypersensitive to HC and HC induces the expression of DNA damage repair genes that repair oxidative DNA damage. HC treated E. coli cells are inhibited from growth and undergo DNA condensation. In vitro HC binds to DNA and cleaves it in presence of copper. Our data strongly indicates HC mediates bacterial cell death by ROS generation and DNA damage. Damage to iron sulfur proteins in the cells contribute to amplification of oxidative stress initiated by HC. Further HC is active against a number of Gram negative bacteria isolated from patients with a wide range of clinical symptoms and varied antibiotic resistance profiles.

Abstract
We present a novel approach of designing and fabricating a noninvasive drug delivery device which is capable of delivering the drug to the target site in a controlled manner. The device utilizes a reservoir which can be reused once the drug has completely diffused from it. This micro-reservoir based fabricated device has been successfully tested using niosomes of insulin drug filled in, which was then sealed with a magnetic membrane of 20 µm thick and was actuated by applying magnetic field. The deflection of the membrane on application of magnetic field results in the drug release from the reservoir. The discharge of the drug solution and the release rates was controlled by external magnetic field. The simulation of the membrane deflection using COMSOL software was carried out to optimize the concentration of the ferrous nanopowder in PDMS matrix. The characterization of the devices was implemented in-vitro on water and in-vivo on Wistar rats. It was also validated using high-performance liquid chromatography (HPLC) by observing characteristic peak of insulin. The blood samples showed the retention time of 2.79 min at λmax of 280 nm which further authenticated the effectiveness of the proposed work. This noninvasive fabricated device provides reusability, precise control and can enable the patient or a physician to actively administrate the drug when required.

Abstract
Previously, we reported that B-cell chronic lymphocytic leukemia (CLL) patients contained elevated levels of microvesicles (MVs). However, given the quiescent nature of CLL B-cells and the relative indolence of the disease, the dynamics of MV generation and their unique phenotypes are not clearly defined. In this study, we find that CLL B-cells generate MVs spontaneously and can be further induced by B-cell receptor-ligation. Most interestingly, CLL B-cells predominantly generate CD52+ MVs, but not CD19+ MVs in vitro, suggesting preferential usage of CD52 into leukemic-MVs and that the CLL plasma MV phenotypes corroborate well with the in vitro findings. Importantly, we detected increased accumulation of CD52+ MVs in previously untreated CLL patients with progressive disease. Finally, sequential studies on MVs in pre- and post-therapy CLL patients demonstrate that while the plasma CD52+ MV levels drop significantly after therapy in most and remain at low levels in some patients, a trend of increased accumulation of CD52+ MVs was detected in majority of post-therapy CLL patients (25 of 33). In total this study emphasizes that dynamic accumulation of CD52+ MVs in plasma can be used to study CLL progression and may be a useful biomarker for patients as they progress and require therapy.

Abstract
The repair of DNA damage caused by ultraviolet radiation (UVR) is well understood in both lower and higher organisms. Genetic studies carried out at optimum temperature for growth, 37 °C in Escherichia coli, have revealed the major pathways of DNA repair. We show that E. coli cells grown at 20 °C are more sensitive to UVR than cells grown at 37 °C. The analysis of knockout mutants demonstrates that cells impaired in recombinational DNA repair pathways show increased UV sensitivity at 20 °C. Cells with mutations in the nucleotide excision repair (NER) pathway genes are highly sensitive to UVR when grown at 37 °C and retain that sensitivity when grown at 20 °C, whereas wild-type cells are not sensitive when grown at 37 °C but become more sensitive to UVR when grown at low temperatures. Our results taken along with reports from the literature suggest that the UVR sensitivity of E. coli cells at low temperature could be due to impaired NER function.

Abstract
The radial glial cell (RGC) is a glial cell type in the central nervous system of all vertebrates. Adult teleost fish have abundant RGCs in the brain in contrast to mammals. Adult fish RGCs have many important functions, including forming a structural scaffold to guide neuronal migration and serving as the progenitor cells in the brain to generate neurons. The role of the RGC in adult neurogenesis explains the high regenerative capacity of adult fish brain. There is increasing evidence from several species that some glial cells produce or metabolize steroids. It is now well-known that teleost RGCs express aromatase and produce estrogens from androgen precursors, which may be important for local neuroendocrine functions and regulation of neurogenesis. The question of whether RGCs are capable of de novo steroid synthesis from cholesterol remains unanswered. However, the expression of steroidogenic acute regulatory protein, and the key enzyme cytochrome P450 17alpha-hydroxylase in primary cultures of goldfish RGCs indicate the potential to produce 17α-hydroxy-pregnenolone and thus other steroid intermediates. The possibility of synthesizing additional non-estrogenic steroids may indicate new functions for the RGC.

Abstract
A new piscean fibroblastic cell line termed as PCF derived from the caudal fin tissue of dark mahseer, Puntius (Tor) chelynoides was established and characterized in the present study which was found to be suitable for toxicity and gene expression studies as in vitro model. The cell line grew well in Leibovitz's L-15 medium supplemented with 10% fetal bovine serum (FBS). The cells were able to grow at a temperature ranging from 20 to 28 °C with an optimal growth at 24 °C and the cell line have been expanded in culture for more than 70 passages. Authentication of the cell line was carried out using mitochondrial DNA markers (Cytochrome Oxidase subunit I and 16S ribosomal RNA). Presence of vimentin in the cells confirmed the fibroblastic origin of cell line. Significant cytopathic effects were observed upon exposure of PCF cell line to bacterial extracellular products and the study also validated the suitability of cell line in transgenic applications as well as in genotoxicity assessment as an in vitro model.

Abstract
Tooth agenesis is one of the most common congenital malformations in humans. Hypodontia can either occur as an isolated condition (non-syndromic hypodontia) or can be associated with a syndrome (syndromic hypodontia), highlighting the heterogeneity of the condition. Though much progress has been made to identify the developmental basis of tooth formation, knowledge of the etiological basis of inherited tooth loss is still lacking. To date, the mutation spectra of non-syndromic form of familial and sporadic tooth agenesis in humans have revealed defects in various such genes that encode transcription factors, MSX1 and PAX9 or genes that code for a protein involved in canonical Wnt signaling (AXIN2), and a transmembrane receptor of fibroblast growth factors (FGFR1). The aim of this paper is to review the current literature on the molecular mechanisms responsible for selective hypodontia in humans and to present a detailed overview of causative genes and syndromes associated with hypodontia.

Abstract
Antioxidants are known to exhibit numerous health benefits including anti-ageing, anti-apoptotic and immuno-stimulatory effects. However, we present the data showing counterproductive effects of therapeutically relevant antioxidants on bacterial clearance by the immune system in a murine peritonitic model. The antioxidants ascorbic acid, glutathione and N-acetylcysteine augmented morbidity and mortality in mice carrying Eshcerichia coli-induced acute bacterial peritonitis. Treatment of peritonitic mice with antioxidants significantly increased their bacterial load in the range of 0.3-2 logs. Antioxidant administration to peritonitic mice resulted in decreased numbers of macrophages, B-cells and dendritic cells at the primary site of infection and increased neutrophil infiltration. Serum TNF-α levels were also decreased in antioxidant-treated peritonitic mice. In vitro experiments showed that antioxidants reduced the phagocytic efficacy of peritoneal macrophages by ~60-75% and also decreased E. coli-induced oxidative burst in macrophages cells. Taken together, our data indicate that the antioxidants increased the severity of peritonitis by decreasing the phagocytic efficiency, oxidative burst, and TNF-α production, and increasing neutrophil infiltration. Based on these results, we propose that antioxidant supplementation during the course of bacterial infection is not recommended as it could be detrimental for the host. In addition, the present study underlines the importance of timing and context of antioxidant administration rather than indiscriminate usage to gain the best possible therapeutic advantage of these redox compounds.

Abstract
The UK National Institute for Health and Clinical Excellence (NICE) recommends that all subfertile women of < 40 years should be entitled to up to three IVF treatment cycles funded by the NHS. The full criteria have been implemented at The Newcastle Fertility Centre at Life since August 2009. The aim of this study was to evaluate the clinical outcome in terms of analysing the cumulative pregnancy rates. A retrospective analysis of data from 812 couples who started their first NHS-funded treatment after August 2009 was undertaken until there were 100 couples who had completed the three treatments. Cumulative pregnancy rates were calculated using life table analysis, and time intervals between treatments were recorded. The number of couples having first, second and third treatment cycles was 812, 298 and 100, respectively. The cumulative clinical pregnancy rates per each fresh cycle were 30.1%, 50.2% and 60.2%, and when frozen embryo transfers were included, they were 33.5%, 53.4% and 62.7%. The median + 2SD time interval between treatments was 11 and 10 months; 90.2% of the women were likely to complete up to three NHS-funded treatment cycles until they achieved a pregnancy. The NICE criteria offer most couples a chance of pregnancy, and the majority will take up the opportunity of undergoing three treatment cycles if required. The time interval between treatments indicated that it will take < 2 years for couples to complete the full course of NHS-funded treatment.

Abstract
Tor tor, commonly called as Tor mahseer, is a high-valued food and game fish endemic to trans-Himalayan region. Mitochondrial cytochrome b (cyt b) gene region of 967 bp was used to estimate the population structure of T. tor. Three populations of T. tor were collected from Narmada (Hosangabad), Ken (Madla), and Parbati river (Sheopur) in Madhya Pradesh, India. The sequence analysis revealed that the nucleotide diversity (π) was low, ranging from 0.000 to 0.0150. Haplotype diversity (h) ranged from 0.000 to 1.000. The analysis of molecular variance analysis indicated significant genetic divergence among the three populations of T. tor. Neighboring-joining tree also showed that all individuals from three populations clustered into three distinct clades. The data generated by cyt b marker revealed interesting insight about population structure of T. tor, which would serve as baseline data for conservation and management of mahseer fishery.

Abstract
An embryonic stem (ES)-like cell culture system RESC from a commercially important freshwater carp, Labeo rohita, was developed using blastula stage embryos. The cells were cultured in Leibovitz-15 (L-15) medium in gelatin-coated cell culture flask supplemented with 15 % fetal bovine serum along with 10 ng ml(-1) basic fibroblast growth factor at 28 °C under feeder-free conditions. The ES-like cells were characterized by their unique morphology, alkaline phosphatase activity, embryoid body formation tendency, expression of transcription factor Oct4, and consistent chromosome count. The RESC cells when treated with retinoic acid differentiated into cells of different lineages. The RESC developed from mid-blastula embryos of L. rohita would be a useful tool for cellular differentiation and gene expression studies.

Abstract
Ompok bimaculatus commonly called as Indian butter catfish is a commercially important food fish and distributed throughout India and Southeast Asia. Genetic differentiation of O. bimaculatus was investigated using cytochrome b (cyt b) gene of three different riverine populations. A total of 37 sequences of cyt b gene (1118 bp) were generated from O. bimaculatus. The mitochondrial DNA analysis revealed that O. bimaculatus has relatively high genetic diversity. The estimated haplotype and nucleotide diversity were 0.063 and 0.005, respectively. The analysis of molecular variance indicated 73.53% genetic variability between the populations and 26.47% genetic variation within population. The understanding of genetic differentiation of O. bimaculatus populations will play a key role in conservation and management of the important endangered fish species.

Abstract
Genetic structure of four wild populations of two hill stream fishes Barilius bendelisis (Ham.1807) and B. barna (Ham. 1822) from Uttarakhand, India, was studied using RAPD markers. Eight selective primers provided distinct and consistent RAPD profiles in both the species, producing a total of 47 and 35 scorable bands in B. bendelisis and B. barna respectively. The bands in the range 666-4,830 bp were scored for consistent results. The RAPD profiles generated by all the eight primers revealed varying degrees of polymorphism (25.00-50.00 %). The average genetic diversity (h) was estimated as 0.1661 and 0.1606 among the four populations of B. bendelisis and B. barna respectively.

Abstract
Puntius is an important genus of freshwater food and ornamental fish belonging to the family Cyprinidae. A total of 60 samples from twelve species of the genus Puntius were collected from eight sampling sites of eight Indian Rivers. Twelve species of Puntius (P. chola, P. sophore, P. filamentosus, P. fasciatus, P. vittatus, P. chelynoides, P. gonionotus, P. denisonii, P. ticto, P. gelius, P. conchonius and P. sarana) were investigated using 60 partial sequences of the mitochondrial cytochrome b (Cyt b, 1096 bp) gene to estimate genetic divergence and to establish the phylogenetic relationship. The average intraspecies diversity was estimated as 0.002, whereas the average interspecies diversity was estimated as 0.177. The sequence analysis of the Cyt b gene revealed four distinct groups, which are genetically distinct species and exhibited identical phylogenetic relationship. The present study validated the utility of the Cyt b gene in genetic diversity and phylogenetic studies.

Abstract
Tor tor is an important game and food fish of India with a distribution throughout Asia from the trans-Himalayan region to the Mekong River basin to Malaysia, Pakistan, Bangladesh and Indonesia. A new cell line named TTCF was developed from the caudal fin of T. tor for the first time. The cell line was optimally maintained at 28°C in Leibovitz-15 (L-15) medium supplemented with 20% fetal bovine serum (FBS). The propagation of TTCF cells showed a high plating efficiency of 63.00%. The cytogenetic analysis revealed a diploid count of 100 chromosomes at passage 15, 30, 45 and 60 passages. The viability of the TTCF cell line was found to be 72% after 6 months of cryopreservation in liquid nitrogen (-196°C). The origin of the cell lines was confirmed by the amplification of 578- and 655-bp sequences of 16S rRNA and cytochrome oxidase subunit I (COI) genes of mitochondrial DNA (mtDNA) respectively. TTCF cells were successfully transfected with green fluorescent protein (GFP) reporter plasmids. Further, immunocytochemistry studies confirm its fibroblastic morphology of cells. Genotoxicity assessment of H₂O₂ in TTCF cell line revealed the utility of TTCF cell line as in vitro model for aquatic toxicological studies.

Abstract
Isolated splenic tuberculosis is an exceedingly rare clinical condition. Microbiological confirmation of diagnosis in such cases is quite difficult. We encountered the case of a 35-year-old female, who presented with persistent low-grade fever and weight loss. The CT scan of the abdomen revealed multiple hypodense splenic lesions. No primary focus of infection was detected in any other organs. Fine needle aspiration of splenic lesion revealed acid-fast bacilli on Ziehl-Neelsen stain. With anti-tuberculous therapy, the lesions regressed significantly in size. We stress that splenic tuberculosis should be considered as a diagnostic possibility even in immunocompetent individuals and choose combination antituberculous therapy as the first line treatment with consideration of splenectomy depending on response.

Abstract
We explore the effect of heteronuclear dipolar recoupling on the satellite and multiple-quantum transitions of a half-integer-spin quadrupolar nucleus coupled to a single spin-12. A three-dimensional experiment is introduced that resolves different quadrupolar sites whilst allowing simultaneous extraction of the quadrupolar coupling constants, asymmetry parameters of the electric field gradient, and the isotropic shifts of the quadrupolar nucleus. The experiment also enables estimation of the heteronuclear dipolar coupling constant between the spin-1/2 and half-integer spin quadrupolar nucleus. The relative orientation of the dipolar tensor with respect to the quadrupolar tensor can be estimated by comparing experiments and simulations. Experimental results are shown on a sample of brucite, Mg((17)OH)(2), where the (1)H-(17)O bond distance is estimated.

Abstract
A sensitivity enhancement scheme aiming at selective adiabatic inversion of a single set of satellite transition sidebands under magic angle spinning has been employed on samples of albite containing a single moderately distorted (27)Al site and zoisite containing two highly distorted octahedral (27)Al sites. Overall enhancements of ∼2.5 for albite and ∼3 for the two AlO(6) sites of zoisite are reported by applying this scheme at different spinning speeds reflecting the versatility of this enhancement scheme which achieves significant signal-to-noise enhancements for the systems with moderately high quadrupolar coupling and high quadrupolar coupling. Repeating the sensitivity enhancement scheme and signal readout several times without allowing for spin-lattice relaxation leads to sensitivity enhancements of factors of ∼4 for albite and ∼5 for zoisite which substantially increases the detectability of the quadrupolar sites. The effectiveness of this scheme at high magnetic field under very fast magic angle spinning has been demonstrated. Finally, the possibility of performing spectral editing by selective enhancement of one of the quadrupolar sites in zoisite whilst keeping the other site unaffected has been explored.

Abstract
A DNA-based barcode identification system that is applicable to all animal species will provide a simple, universal tool for the identification of fish species. The barcode system is based on sequence diversity in subunit 1 cytochrome c oxidase (COI) gene. Identification and characterization of fish species based on morphological characters are sometimes found to be erroneous and environmentally affected. There are no studies on the genus Ompok in India at molecular level and species identification of the Ompok is usually carried out through morphological features. A total of 106 samples from three species Ompok pabda, O. pabo and O. bimaculatus were collected from eight sampling sites of seven Indian rivers. One hundred and six sequences were generated from COI region of three Ompok species and 21 haplotypes were observed. The sequence analysis of COI gene revealed three genetically distinct Ompok species and exhibited identical phylogenetic resolution among them. The partial COI gene sequence can be used as a diagnostic molecular marker for identification and resolution of taxonomic ambiguity of Ompok species.

Abstract
Symptomatic benign migratory glossitis (BMG) or "geographic tongue" is a rare occurrence in pediatric dentistry though asymptomatic BMG is comparatively common. BMG presents itself as an ulcer-like region on the dorsum of the tongue, which may recur at different sites on the tongue, creating a migratory appearance. Asymptomatic cases usually resolve on their own but symptomatic cases need treatment. Fissured tongue is a benign condition characterized by deep grooves on the dorsum of the tongue and, in many cases, is associated with geographic tongue. This article presents a case of symptomatic geographic tongue with fissured tongue with a history of asthma.

Abstract
Puntius (Tor) chelynoides, commonly known as dark mahseer, is a commercially important coldwater fish species which inhabits fast-flowing hill-streams of India and Nepal. Cell culture systems were developed from eye, fin, heart and swim bladder tissues of P. chelynoides using explant method. The cell culture system developed from eye has been maintained towards a continuous cell line designated as PCE. The cells were grown in 25cm(2) tissue culture flasks with Leibovitz' L-15 media supplemented with 20 % fetal bovine serum (FBS) at 24°C. The PCE cell line consists of predominantly fibroblast-like cells and showed high plating efficiency. The monolayer formed from the fin and heart explants were comprised of epithelial as well as fibroblast-like cells, a prominent and rhythmic heartbeat was also observed in heart explants. Monolayer formed from swim bladder explants showed the morphology of fibroblast-like cells. All the cells from different tissues are able to grow at an optimum temperature of 24°C and growth rate increased as the FBS concentration increased. The PCE cell line was characterized using amplification of mitochondrial cytochrome oxidase subunit I (COI) & 16S rRNA genes which confirmed that the cell line originated from P. chelynoides. Cytogenetic analysis of PCE cell line and cells from fin revealed a diploid count of 100 chromosomes. Upon transfection with pEGFP-C1 plasmid, bright fluorescent signals were observed, suggesting that this cell line can be used for transgenic and genetic manipulation studies. Further, genotoxicity assessment of PCE cells illustrated the utility of this cell line as an in vitro model for aquatic toxicological studies. The PCE cell line was successfully cryopreserved and revived at different passage levels. The cell line and culture systems are being maintained to develop continuous cell lines for further studies.

Abstract
The goal of modern dentistry is to manage non-cavitated carious lesions non-invasively through remineralization in an attempt to prevent disease progression, and to improve strength, esthetics, and function of teeth. The emphasis currently is being given to new technologies for enamel remineralization which suggest the changes in the understanding of dental caries. The aim of this paper is to review the contemporary non-fluoridated systems available for remineralization therapy and ideas for their implementation into clinical practice. A search of articles from "Pubmed" and "Medline" with the keywords Remineralization-demineralization, Casein derivatives, Non-fluoridated remineralizing agents was conducted. A total of 526 abstracts were collected, out of which 172 articles that discussed current technologies of non-fluoridated remineralizing agents were read and 33 most relevant articles were included in this paper. Casein phosphopeptide based technology has been established as a strong non-fluoridated remineralizing agent fulfilling all the criteria of an ideal remineralizing material.
