Abstract
We report molecular mapping and inheritance of restoration of fertility (Rf) in A4 hybrid system in pigeonpea. We have also developed PCR-based markers amenable to low-cost genotyping to identify fertility restorer lines. Commercial hybrids in pigeonpea are based on A4 cytoplasmic male sterility (CMS) system, and their fertility restoration is one of the key prerequisites for breeding. In this context, an effort has been made to understand the genetics and identify quantitative trait loci (QTL) associated with restoration of fertility (Rf). One F2 population was developed by crossing CMS line (ICPA 2039) with fertility restorer line (ICPL 87119). Genetic analysis has shown involvement of two dominant genes in regulation of restoration of fertility. In parallel, the genotyping-by-sequencing (GBS) approach has generated ~ 33 Gb data on the F2 population. GBS data have provided 2457 single nucleotide polymorphism (SNPs) segregating across the mapping population. Based on these genotyping data, a genetic map has been developed with 306 SNPs covering a total length 981.9 cM. Further QTL analysis has provided the region flanked by S8_7664779 and S8_6474381 on CcLG08 harboured major QTL explained up to 28.5% phenotypic variation. Subsequently, sequence information within the major QTLs was compared between the maintainer and the restorer lines. From this sequence information, we have developed two PCR-based markers for identification of restorer lines from non-restorer lines and validated them on parental lines of hybrids as well as on another F2 mapping population. The results obtained in this study are expected to enhance the efficiency of selection for the identification of restorer lines in hybrid breeding and may reduce traditional time-consuming phenotyping activities.

Abstract
Background Teeth restored with direct composite resin are constantly exposed to specific challenges of the oral cavity. These challenges can modify the material properties and, when associated with daily brushing, eventually change its surface roughness, allowing bacterial growth and retention of extrinsic pigments. Dentifrices plays an important role in dental wear (abrasion) and over time, can also cause an increase in the surface roughness of restorative materials. Objective To assess the effect of dentifrices on the longevity of direct nanofilled composite resins restorations as far as wear and roughness is concerned. Method Class V cavity were prepared on 90 extracted human teeth and restored with Filtek Z350 composite. Teeth were randomly divided into 6 experimental groups of 15 each labelled as Group-1 (Colgate Dental cream) Group-2 (Colgate Active Salt toothpaste), Group-3 (Pepsodent Regular toothpaste), Group-4 (Dabur red toothpaste), Group-5 (Dabur Lal tooth powder) and Group-6 Control (water). The samples were fixed on tooth brushing machine and subjected to mechanical tooth brushing using various dentifrices according to respective groups in 3 phases and reading of surface roughness (Ra) was recorded. Result Surface roughness (Ra) had increased in following order: Group 6 < Group 3 < Group 2 < Group 1 < Group 4 < Group 5. All the tooth pastes were compared, their behaviour was found to be similar as there was no statistically significant difference amongst them. Though all of them were inferior to control group and the difference was statistically significant. Whereas the only tooth powder Dabur lal tooth powder gave the maximum roughness when compared with the other tooth pastes and the difference was statistically significant. Conclusion With increase in time of brushing there was increase in surface roughness in all the 5 dentifrices among them Ra was maximum for Dabur lal tooth powder.

Relative gene expression of fatty acid synthesis genes at 60 days postpartum in bovine mammary epithelial cells of Surti and Jafarabadi buffaloes. Vet World 2017; 10:467-476. [PMID: 28620248 PMCID: PMC5465758 DOI: 10.14202/vetworld.2017.467-476] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2016] [Accepted: 03/22/2017] [Indexed: 11/30/2022] Open
Abstract
Aim: Aim of the study was to study the relative gene expression of genes associated with fatty acid synthesis at 60 days postpartum (pp) in bovine mammary epithelial cells (MECs) of Surti and Jafarabadi buffaloes. Materials and Methods: A total of 10 healthy Surti and Jafarabadi buffaloes of each breed were selected at random from Livestock Research Station, Navsari and Cattle Breeding Farm, Junagadh, Gujarat, respectively, for this study. Milk sample was collected from each selected buffalo at day 60 pp from these two breeds to study relative gene expression of major milk fat genes using non-invasive approach of obtaining primary bovine MECs (pBMEC) from milk samples. Results: In this study overall, the relative expression of the six major milk lipogenic genes butyrophilin subfamily 1 member A1 (BTN1A1), stearoyl-CoA desaturase (SCD), lipoprotein lipase (LPL), glycerol-3-phosphate acyltransferase mitochondrial (GPAM), acetyl-coenzyme A carboxylase alpha (ACACA), and lipin (LPIN) did not show changes in expression patterns at 60th day of lactation in both Surti and Jafarabadi buffaloes. Conclusion: The pBMEC can be successfully recovered from 1500 ml of milk of Surti and Jafarabadi buffaloes using antibody-mediated magnetic bead separation and can be further used for recovering RNA for down step quantification of major milk lipogenic gene expression. The relative expression of the six major milk lipogenic genes BTN1A1, SCD, LPL, GPAM, ACACA, and LPIN did not show changes in expression patterns in both Surti and Jafarabadi buffaloes, suggesting expression levels of lipogenic genes are maintained almost uniform till peak lactation without any significant difference.

Abstract
In preliminary studies we found that benzopyrones (coumarins), which are known to exert many biological activities including anti-inflammatory effect, possess promising macrofilaricidal action as well. In order to explore the possibility of combining such a macrofilaricidal activity with the microfilaricidal potential of the known piperazine pharmacophore, we synthesized a series of compounds and evaluated their antifilarial effect. In the present study, one of these compounds, 7-O-[4-methyl piperazine-1-(2-acetyl)]-2H-1-benzopyran-2-one (2), which has shown promising macrofilaricidal action against rodent filariid Litomosoides carinii in cotton rats, was evaluated against infection with Brugia malayi in Mastomys coucha and jird (Meriones unguiculatus). In the B. malayi-M. coucha system, the compound at a dose of 300 mg/kg, oral (p.o.) x5 days showed 53.6% adulticidal and 46.0% microfilaricidal activity along with 46.3% sterilization effect on the female worms. In addition, the compound interfered with the establishment of infective larvae (L(3))-induced infection to an extent of 50% at the same dose level. At 1 microM concentration it inhibited protease activity of B. malayi to 82%. The compound thus provides a novel lead for further synthesis and development of antifilarial agents with macrofilaricidal, microfilaricidal, female-sterilizing and possible larvicidal efficacy.

Abstract
Present study was undertaken to evaluate the suitability of natural (Culex quinquefasciatus) and experimental (Aedes aegypti) vectors for supporting the development of W. bancrofti larvae for onward transmission. Both the species permitted development of W. bancrofti mf to infective larvae (L3) within 11 to 13 days. The mf intake by both the species of mosquitoes was directly related to mf density in donor's blood. Culex exhibited higher L3 recovery than Aedes. In Aedes maximum percent L3 development occurred after ingesting 4 mf whereas Culex exhibited best establishment at an average mf intake of 11.5. Nevertheless wide variation in mf density in donor's blood did not significantly affect the larval establishment in Aedes mosquito while in Culex very high (> 400 mf/40 microliters) or low (< 50 mf/40 microliters) mf counts in donor's blood adversely affected the L3 recovery. The results reveals that A. aegypti has an edge over the natural vector, Culex in being a voracious feeder, their easy laboratory maintenance and better transmission potential.

Abstract
ICRP Publications 53, 62 and 80 give organ dose coefficients and effective doses to ICRP Reference Man and Child from established nuclear medicine procedures. However, an average Indian adult differs significantly from the ICRP Reference Man as regards anatomical, physiological and metabolic characteristics, and is also considered to have different tissue weighting factors (called here risk factors). The masses of total body and most organs are significantly lower for the Indian adult than for his ICRP counterpart (e.g. body mass 52 and 70 kg respectively). Similarly, the risk factors are lower by 20-30% for 8 out of the 13 organs and 30-60% higher for 3 organs. In the present study, available anatomical data of Indians and their risk factors have been utilised to estimate the radiation doses from administration of commonly used 99Tcm-labelled radiopharmaceuticals under normal and certain pathological conditions. The following pathological conditions have been considered for phosphates/phosphonates--high bone uptake and severely impaired kidney function; IDA--parenchymal liver disease, occlusion of cystic duct, and occlusion of bile duct; DTPA--abnormal renal function; large colloids--early to intermediate diffuse parenchymal liver disease, intermediate to advanced parenchymal liver disease; small colloids--early to intermediate parenchymal liver disease, intermediate to advanced parenchymal liver disease; and MAG3--abnormal renal function, acute unilateral renal blockage. The estimated 'effective doses' to Indian adults are 14-21% greater than the ICRP value from administration of the same activity of radiopharmaceutical under normal physiological conditions based on anatomical considerations alone, because of the smaller organ masses for the Indian; for some pathological conditions the effective doses are 11-22% more. When tissue risk factors are considered in addition to anatomical considerations, the estimated effective doses are still found to be generally somewhat higher for the Indian, for both normal and pathological states (but lower than the values based on anatomical considerations alone). However, when the radiopharmaceutical is administered in quantities proportional to the body mass, the effective doses are 11-28% lower for the Indian under both normal and pathological conditions. It may be concluded that Indians are at a lower risk of radiation health detriment in comparison with the ICRP adult on administration of the various 99Tcm-labelled radiopharmaceuticals considered in this study.

Abstract
To investigate the cell-mediated immune (CMI) responses of the host during the development of acute filarial disease manifestations, we studied the sequential changes in CD4+ and CD8+ T-cell subsets, leukocyte migration inhibition (LMI) response to Brugia malayi adult worm antigen, and concanavalin-A (ConA) and filarial antigen-induced lymphocyte transformation (LT) in the Indian leaf monkey (Presbytis entellus)-B. malayi model. Filarial infection was established in monkeys by subcutaneous inoculations of infective larvae (L3) (700-1,250 L3/monkey) in multiple doses, and the infected monkeys were categorized as symptomatic (Sym) and asymptomatic (Asym) depending on whether or not acute clinical manifestations were shown by them. In Sym monkeys, LMI response to homologous adult parasite antigen was significantly suppressed as compared to Asym monkeys. In Asym monkeys, LMI response varied among the animals; 2 showed an increase throughout the study period and 2 showed suppression at different time points. When compared with Asym monkeys, CD8+ T cells in Sym monkeys showed a trend of significant increase after day 180 postinoculation (PI). CD4+ T cells remained within the normal range till day 300 (PI), after which they showed a marginal increase. ConA-stimulated LT was suppressed in Asym monkeys from day 60 PI. Antigen-stimulated LT was unresponsive in both Asym and Sym animals. Thus, the host's LT response to ConA is suppressed in Asym animals, and alteration in CD8+ T-cell number and LMI response in Sym monkeys may be involved in the development of the acute disease manifestations in this model.

Abstract
Humoral immune responses of the Indian leaf monkey (Presbytis entellus) experimentally infected with Brugia malayi and exhibiting disease manifestations were studied. Microfilaraemia, filaria-specific IgG and circulating immune complexes (CICs) were determined in the monkeys at different time-points after inoculation of B. malayi 3rd-stage larvae. Sera were analysed for recognition pattern of adult parasite antigen molecules by immunoblotting. More than 60% of the infected monkeys developed episodic or persistent limb oedema with or without fever and with low or no microfilaraemia. While both CIC and filaria specific IgG levels were comparable in animals showing no disease symptoms (asymptomatics) and some animals showing symptoms (symptomatics), IgG levels peaked during pre-patent stage in symptomatics and during latent stage in asymptomatic animals. However, some of the symptomatic animals showed a low level of filaria-specific IgG as compared to asymptomatic and other symptomatic animals. The immunoblot analysis showed non-reactivity of 17 and 55 kDa antigens with sera of symptomatic animals. The results thus suggest that humoral immune responses as measured in the present study do not precede the development of the manifestations. However, 2 non-reactive antigen molecules identified by symptomatic sera need further study to establish their possible involvement, if any, in the development of acute disease manifestations in this model.

Abstract
Investigations on various aspects of human filariasis using target filarial parasite, Brugia malayi is jeopardised to a great extent due to its prolonged incubation period and poor harvest from the existing experimental animal models. To obviate these difficulties it was decided to establish B. malayi infection in immunosuppressed Mastomys coucha. Cortisone, a well-known immunosuppressant, was used at 10-mg/kg dose level subcutaneously in two courses each of 5 days duration. The first course was administered 1 week before and the second, 1 week after infective exposure. Mastomys were exposed either with 100 or 200 L3 each. Untreated age-matched animals were also exposed simultaneously. The minimum prepatent period was observed to be 90.7 days in immunosuppressed animals exposed to 200 L3. The course of microfilaraemia in immunosuppressed and control animals was identical up to 180 days of observation period. However, the adult worm recovery from the former group of mastomys was higher. It is surmised that exposure with B. malayi L3 in immunosuppressed mastomys would be of great advantage in getting larger harvests of adult worms of B. malayi.

Abstract
The fate of intraperitoneally inoculated infective third-stage larvae (L3) of the nematode Brugia malayi Lichtenstein and the status of the peritoneal macrophage function were investigated in the susceptible rodent hosts Mastomys natalensis Roberts and Meriones unguiculatus Milne-Edwards (jird). Jirds and M. natalensis were inoculated intraperitoneally with 125 and 250 L3 and the worm burden and peritoneal macrophage function in the two species were compared at different days post-inoculation (DPI). None of the infected M. natalensis had adult worms in the peritoneal cavity; very few degenerating L3 surrounded by peritoneal cells were recovered 7 and 15 DPI. In contrast, all the infected jirds showed the parasite in different stages of development and the worm burden at different days PI was more in 250 L3 dose group than in 125 L3 dose group. The phagocytic function of peritoneal macrophages of normal M. natalensis was twice higher than that of jirds. This function was found significantly suppressed in both host species at 15 DPI; at 35 DPI, the activity was still at this low level in the jird, while that in M. natalensis reverted to uninfected age- and sex-matched control levels. These findings demonstrate that the peritoneal environment of M. natalensis is not conducive to the development of B. malayi and this is probably related to high macrophage activity in the peritoneum of this host compared to that found in the jird.

Abstract
Successful experimental transmission of the human lymphatic dwelling nocturnal periodic strain of Wuchereria bancrofti has been achieved from man to Indian leaf monkey (Presbytis entellus) through a susceptible strain of Aedes aegypti. The prepatent period varied between 195 and 240 days. Microfilaria (mf) levels were in general low and the peak count was attained at 1800 hr. Of the adult worms 5-12.5% were recovered from male langur while females revealed poor (2.54%) recovery. This host--parasite model thus makes available the target parasite material in substantial quantity to work on chemotherapeutic and immunological investigations.

Abstract
The effect of immunopotentiators (Freund's complete adjuvant and CDRI Compound no. 84/201) has been evaluated on exertion of antifilarial activity of diethylcarbamazine (DEC) at different dose levels in Mastomys natalensis experimentally infected with Brugia malayi. DEC alone exhibited dose dependent micro- as well as macrofilarial action. In combination with immunomodulators, activity of DEC was significantly enhanced even at a lower dose level (12.5 mg/kg). However at higher dose level (> 25 mg/kg) of the drug along with immunostimulator the adulticidal activity was significantly reduced. Nevertheless, immunopotentiators themselves displayed certain amount of antifilarial action (34-38% macrofilaricidal).

Abstract
To obtain comparable and reproducible results by filaria skin test with B. malayi larval antigen, standard procedure has been evolved. Antigen protein of 2 micrograms per test, injected intracutaneously, was found optimum for positive skin reaction. The reaction ratio based on increase of wheal area by 2 times or more was found to be statistically significant for interpreting positive results. However, in larger field trials, the simpler measurement of increase of wheal diameter by 1 1/2 times or more was found to be equally reliable. Patients treated with diethylcarbamazine citrate, antihistaminics and anti-inflammatory drugs are likely to be unresponsive to filarial antigen and will yield incorrect information.
