Abstract
Salmonella Typhimurium (STM) is a facultative anaerobe and one of the causative agents of nontyphoidal salmonellosis (NTS). Its anaerobic metabolism is enabled under the hypoxic environment that is encountered inside macrophages and the gut lumen of the host. In both of these niches, free radicals and oxidative intermediates are released by neutrophils as an inflammatory response. These chemical species further undergo reactions to produce nitrate, which is preferably taken up by STM as an electron acceptor in the absence of oxygen. NarL, the response regulator of the two-component regulatory system NarX/L, and a transcription factor, gets activated under anaerobic nitrate-rich conditions and upregulates the nitrate reduction during anaerobic respiration of STM. To understand the role of NarL in the pathogenesis of STM, we generated a narL-knockout (STM:ΔnarL) as well as a narL-complemented strain of STM. Anaerobically, the mutant displayed no growth defect but a significant attenuation in the swimming (26%) and swarming (61%) motility, and biofilm-forming ability (73%) in vitro, while these morphotypes got rescued upon genetic complementation. We also observed a downregulation in the expression of genes associated with nitrate reduction (narG) and biofilm formation (csgA and csgD) in anaerobically grown STM:ΔnarL. As compared with wild STM, narL mutant exhibited a threefold reduction in the intracellular replication in both intestinal epithelial cells (INT- 407) and monocyte-derived macrophages of poultry origin. Further, in vivo competitive assay in the liver and spleen of the murine model showed a competitive index of 0.48 ± 0.58 and 0.403668 ± 0.32, respectively, for STM:ΔnarL.

Abstract
Blood feeding and digestion are vital physiological activities essential for the survival and reproduction of ticks. Chemical acaricides viz., ivermectin, amitraz and fipronil, are known to act on the central nervous system, resulting in the mortality of ticks. The present study is focused on the effect of these acaricides on the midgut and gut enzymes of Rhipicephalus microplus. The ultra-thin sections of midgut of ivermectin-treated ticks showed irregular basal membrane and ruptured digestive vesicles. Amitraz treatment resulted in a notable decrease in digestive cells with pleats in the basal membrane, while fipronil-exposed ticks exhibited reduced digestive cells, loss of cellular integrity, and disintegration of the basal membrane and muscle layer. The gut tissue homogenate of ivermectin and fipronil treated ticks showed a significant reduction of cathepsin D level, 76.54 ± 3.20 μg/mL and 92.67 ± 3.72 μg/mL, respectively, as compared to the control group (150.0 ± 3.80 μg/mL). The leucine aminopeptidase level (4.27 ± 0.08 units/mL) was significantly decreased in the ivermectin treated ticks compared to other treatment groups. The acid phosphatase activity (29.16 ± 0.67 μmole/min/L) was reduced in the ivermectin treated group whereas, increased activity was observed in the fipronil and amitraz treated groups. All the treatment groups revealed increased alkaline phosphatase levels (17.47-26.72 μmole/min/L). The present finding suggests that in addition to the established mechanism of action of the tested acaricides on the nervous system, the alterations in the cellular profile of digestive cells and enzymes possibly affect the blood digestion process and thus the synthesis of vital proteins which are essential for vitellogenesis, and egg production in ticks.

Abstract
Hyalomma anatolicum is the principal vector for Theileria annulata, T. equi, and T. Lestoquardi in animals and the Crimean-Congo hemorrhagic fever virus in humans. Due to the gradual loss of efficacy of the available acaricides against field tick populations, the development of phytoacaricides and vaccines has been considered the two most critical components of the integrated tick management strategies. In the present study, in order to induce both cellular and humoral immune responses in the host against H. anatolicum, two multi-epitopic peptides (MEPs), i.e., VT1 and VT2, were designed. The immune-stimulating potential of the constructs was determined by in silicoinvestigation on allergenicity (non-allergen, antigenic (0.46 and 1.0046)), physicochemical properties (instability index 27.18 and 35.46), as well as the interaction of constructs with TLRs by docking and molecular dynamics analysis. The immunization efficacy of the MEPs mixed with 8% MontanideTM gel 01 PR against H. anatolicum larvae was determined as 93.3% and 96.9% in VT1- and VT2-immunized rabbits, respectively. Against adults, the efficacy was 89.9% and 86.4% in VT1- and VT2-immunized rabbits, respectively. A significant (p < 0.001) reduction in the anti-inflammatory cytokine (IL-4) and significantly higher IgG response was observed in a VT1-immunized group of rabbits as compared with the response observed in the control group. However, in the case of the VT2-immunized rabbits, an elevated anti-VT2 IgG and pro-inflammatory cytokine (IL-2) (>30 fold) along with a decreased level of anti-inflammatory cytokine IL-4 (0.75 times) was noted. The efficacy of MEP and its potential immune stimulatory responses indicate that it might be useful for tick management.

Abstract
OBJECTIVE The present lab-based investigation aimed at evaluating the canal disinfectants using photodynamic therapy (PDT) using different photosensitizers, conventional NaOCl, a mixture of doxycycline, citric acid, and a detergent (MTAD) and their impact on the bond strength of glass fiber post to radicular dentin. MATERIALS AND METHODS Forty extracted human premolars were gathered and disinfected. The decoration was performed up to the cementoenamel junction. Using the crown down technique cleaning of the canal was done following rinse with distilled water. All canals were dried with paper points and obturated with gutta-percha. Post space was prepared using peso reamers and samples were randomly allocated into four groups following different disinfection regimes: Group 1 - Methylene blue photosensitizer (MBP) + MTAD; Group 2 - RBP (Rose Bengal photosensitizer) + MTAD; Group 3 - CP (curcumin photosensitizer) + MTAD and Group 4 - 2.25% NaOCl + MTAD (control). Following disinfection, the canals were dried and the post was placed and cemented within the canal. Samples were dissected at coronal, middle, and apical third and placed in a universal testing machine for push-out bond strength (PBS). Debonded surfaces were evaluated for failure modes. PBS was examined using a one-way analysis of variance (ANOVA). The means of PBS were compared using Tukey multiple comparison tests with a significance threshold of (p<0.05). RESULTS Group 3 canals disinfected with CP and MTAD had the highest PBS at two levels: cervical (9.57±1.21 MPa), middle (6.37±0.79 MPa), and group 2 canal space disinfected by RBP and MTAD had the maximum PBS in apical portion (5.35±0.42 MPa). No significant difference at all root levels between group 2 (RBP + MTAD) and group 3 (p>0.05). Canal irrigation with group 1 (MBP + MTAD) and group 4 control (2.25% NaOCl + MTAD) exhibited comparable PBS at all three levels of the root. CONCLUSIONS CP, MTAD, RBP and MTAD for canal disinfection and bonding of glass fiber post to radicular dentin demonstrated comparable bond values at all three root levels and can be recommended in clinical settings after further investigations.

Abstract
Type 2 diabetes mellitus (T2DM) is characterised by the chronic hyperglycaemia which leads to various micro and macrovascular complications. The aim of present study was to evaluate the impact of talk test based aerobic exercise on glycaemic control and anthropometric measures among adults with (T2DM). In this double blind randomised controlled trial (RCT), aerobic exercises/walking was used as intervention. The patients were divided into three groups based on the tool of exercise intensity prescription: a talk test-based group (TTG, n=30), a rating of perceived exertion-based group (RPEG, n=30), and a control group (CG, n=30). Glycated haemoglobin (HbA1c) was evaluated at baseline and after 8 weeks. Anthropometric measures, i.e. body mass index (BMI), and waist circumference (WC) were evaluated at baseline, 4 weeks, and 8 weeks. Wilcoxon rank-sum/repeated measure of ANOVA and Kruskal-Wallis test/ANOVA were used for within and between group comparison, respectively, on the basis of normality of the data. The mean HbA1c change in TTG, RPEG, and CG was -0.29, -0.28, and -0.04, respectively, and it was significantly greater in TTG and RPEG as compared to CG. The reduction of HbA1c, BMI, and WC was reported in each group. However, the reduction in the experimental groups, i.e. TTG and RPEG was significantly greater than in the control group (P≤0.01). However, there was no significant difference found between the experimental groups (P>0.05). TT based aerobic exercise is effective in improving glycaemic control and anthropometric measures. Therefore, TT can be used for the exercise prescription of these patients. The study is registered at the Clinical Trial Registry-India under no. CTRI/2019/02/017531.

Abstract
Abstract
Study question
Does adding gonadotropin-releasing hormone agonist (GnRHa) to hCG trigger increases the number of high-grade embryos in GnRH antagonist protocol in fresh non-donor IVF?
Summary answer
Final oocyte maturation triggered by dual trigger increases the number of MII oocytes thus transferring good-quality embryos and cryopreserving surplus embryos compared to hCG trigger.
What is known already
hCG has been conventionally used as a ‘faux’ LH surge to bring about final oocyte maturation due to structural similarity between the two. GnRH agonist, on the other hand, induces a more physiological gonadotropin surge for follicular maturation, but is associated with luteal phase deficiency. Recent studies have shown that combining GnRHa with hCG trigger improves oocyte maturation and embryo quality with the added benefit of a luteal phase support, thereby improving IVF outcomes in terms of both embryological and reproductive outcomes.
Study design, size, duration
A single-center, open labelled, randomized controlled trial including 100 normal responder patients between 21-38 years undergoing IVF using GnRH antagonist protocol between January 2020 to August 2021. The study excluded patients with the presence of other variables of adverse outcomes like diminished ovarian reserve (AFC < 5 or AMH < 1.2 ng/ml), endocrine disorders, thin endometrium (<6mm), previous history of uterine surgeries, and high responders.
Participants/materials, setting, methods
100 patients undergoing fresh IVF cycle using GnRH antagonist protocol were randomized after informed consent to receive either dual trigger (Leuprolide acetate 1 mg + rhCG 250 mcg, n = 50) or single hCG trigger (rhCG 250 mcg, n = 50). Oocyte retrieval was done 35-37 hours after trigger followed by IVF/ICSI, as indicated. Oocyte and embryo grading was done using Istanbul consensus. Analysis was done by ITT. Outcomes were analyzed using Independent t-test and Chi-square test.
Main results and the role of chance
The baseline characteristics were comparable in both arms. the number of MII oocytes retrieved (7.82 versus 5.92, p = 0.003) and the number of day-3 grade-1 embryos (4.24 versus 1.8, p < 0.001) were higher in the dual trigger group, whereas fertilization rates between the two groups (91.82% versus 88.51%, p=NS) were comparable. Consequently, the number of embryos cryopreserved (2.68 versus 0.94, p < 0.001) were significantly higher in the dual trigger group. However, the implantation rate between the two groups (21% versus 19.6%, p = 0.770) was comparable. The serum LH levels 12 hours post trigger were measured in both the arms and as expected, high serum LH values were documented in the dual trigger group (46.23 mIU/ml vs 0.93 mIU/ml, p < 0.0001).
Limitations, reasons for caution
Due to the impact of the Covid-19 pandemic causing an intermittent pause in IVF services at our center, a smaller sample size of 100 patients could be enrolled in the study, and reproductive outcomes in terms of live births and cumulative live births could not be assessed
Wider implications of the findings
This study, though small, has contributed to some evidence of redesigning the dual trigger in all antagonist cycles, with the exception of high responders and PCOS patients. The addition of GnRHa to hCG trigger has led to the possibility of cryopreserving surplus embryos thereby increasing the cumulative live births.

Abstract
Abstract
Study question
Does intra-ovarian instillation of platelet rich plasma (PRP) improves the clinical outcome of IVF cycles in women with Diminished Ovarian reserve (DOR)?
Summary answer
PRP instillation leads to consistent improvement in Antral follicle count (AFC), thus achieving clinical pregnancy rate of 33.3% per cycle in women with DOR.
What is known already
There is rising incidence of females with diminished ovarian reserve (DOR) especially among Asian ethnicity. With the emergence of regenerative medicine, multiple studies have evaluated the role of intra-ovarian PRP, demonstrating a beneficial role in improving ovarian reserve parameters (serum Follicular stimulating hormone (FSH), serum anti-Mullerian hormone (AMH), AFC). Despite its’ favorable effects on biochemical markers and AFC, data regarding improvement in clinical outcome remains elusive and led to inception of this study.
Study design, size, duration
A prospective interventional study was conducted at Division of Reproductive Medicine of a tertiary care institute. 41 infertile females aged 20-39 years with DOR (AMH <1.2 ng /ml; AFC<5) were enrolled in the study during a 6-month period beginning from August 2021.
Participants/materials, setting, methods
After informed consent, patients received fresh autologous PRP, prepared from 30 ml venous blood. 1.5ml of PRP instilled in each ovarian stroma between day 7-10 of menstrual cycle under sedation. Patients were followed up for three-consecutive months to assess ovarian reserve parameters including serum FSH, AMH and AFC. Patients showing significant improvement in parameters were recruited for fresh IVF cycles using Antagonist protocol with 1% transdermal testosterone. Outcomes were analysed using linear mix effect model.
Main results and the role of chance
The average platelet concentration in PRP was ∼10,00,000 platelets/µL. The mean age of enrolled patients was 31.22±4.16 years. Linear improvement in AFC (3.63 vs 6.98 vs 7.97 vs 6.90, p<0.001) was observed from baseline to three consecutive follow-up months with maximal response witnessed in second month in 57.1% of those undergoing IVF cycle. However, there was no significant difference in Serum FSH (p=0.11) and AMH (p=0.16) from the baseline post intervention. Of the 41 patients, 35 (85.3%) responded to the treatment and underwent IVF antagonist cycle. 5 out of 35 IVF cycles were cancelled mid-cycle due to poor ovarian response. The mean dose of gonadotropin requirement was 2667.5±281.1 IU (Follicular stimulating hormone) and 1400±337.3 IU (Human menopausal gonadotropin). The average number of oocytes retrieved was 5.7±2.2 whereas mean number of MII oocytes was 4.63±1.85. The fertilization rate and the cleavage rate were 92.4% and 74.1% respectively. Of the thirty patients, eight patients underwent day 2 transfer due to poor grade of embryos. Mean number of grade 1- day 3 embryos was 1.25±0.55 with surplus embryos available for cryopreservation in 14 patients. The overall clinical pregnancy rate per transfer was 33.33%. No adverse events were reported.
Limitations, reasons for caution
This was a prospective single arm study. A randomized controlled trial comprising a “no-treatment” arm would establish a Level-I evidence. However, “no-treatment” arm in a developing country like ours, imposes financial burden on the couple with no guaranteed clinical success and thus raising ethical concern and need for ovarian rejuvenation.
Wider implications of the findings
With the impetus to provide a biological child to these DOR women, intra-ovarian PRP instillation as a method of ovarian rejuvenation holds promising results. Evidently, PRP is not only effective in improving ovarian reserve but this translates into an improved reproductive outcome in a population, previously limited to oocyte donation.

Abstract
Literature has proved the benefit of exercise on pulmonary functions among the patients with type 2 diabetes mellitus (T2DM). However, objective tools of exercise intensity prescription have been used in previous trials. The trials to explore the effectiveness of subjective tools-based exercise on pulmonary functions among these patients are scarce. The purpose of this study was to explore the feasibility of subjective tools-based exercise among patients with T2DM. Another objective was to see the effectiveness of this kind of exercise on pulmonary functions among patients with T2DM. 49 patients were randomly allotted to three groups, talk test group (TTG, n=16); rating of perceived exertion group (RPEG, n=16); and control group (CG, n=17). Subjects were evaluated for five progression criteria. The intervention period for the groups was 8 weeks. Recruitment and retention rate was 62.82 and 75.5%, respectively. Adherence rate was 67.34% and 58.91% for supervised and unsupervised sessions, respectively. 78.38% of the patients were available for post-intervention outcome evaluation. A significant increase in pulmonary functions in both the experimental groups (P=0.00) was found after 8 weeks of training. This study provides evidence that a trial of this nature is feasible with a few amendments in methodology. Additionally, the study also concluded that the subjective tool based aerobic exercise may be effective in improving pulmonary functions among patients with T2DM.

Abstract
Hypertension is the most metastasizing non-communicable disease, which has affected more than 1.4 billion people, worldwide. Exercise is the core management strategy for hypertensive individuals. Extensive literature is available for each kind of exercise that is isometric hand grip training (IHGT), resistance training (RT), and aerobic training (AT). However, the comparison between these exercise regimens has not been done in a single trial. The trial was conducted on 126 subjects in Hisar, an urban area of Haryana (INDIA), from July 2017 to December 2018. Subjects were randomly assigned to four groups: control (n=33), IHGT (n=32), RT (n=31), and AT (n=30). Study variables were measured at baseline, 2nd week, 4th week, 6th week, and also after the 8th week of intervention. Experimental groups showed significant reduction in all the components of blood pressure in comparison to control group. The RT group showed maximum reduction in blood pressure in comparison to other regimens (systolic blood pressure: RT > IHGT > AT; diastolic blood pressure: RT > AT > IHGT). However, the difference between the groups is not statistically significant (P>0.05). The study findings reveal that different kind of exercise regimens are equally effective in lowering blood pressure among pre hypertensive and stage 1 hypertension adults.

Abstract
Patients recovering from coronary artery bypass grafting (CABG) are particularly vulnerable to impaired functional capacity, as well as quality of recovery because in addition to the direct effect of heart disease on cardiac performance, the surgical procedure and preoperative factors also contribute to loss of function. Early moderate intensity walking protocols can be effective in improving the health status of these patients. Still, there is hardly any evidence about the effect of early moderate intensity walking after CABG in the patients having high risk preoperative status for pulmonary complications. Therefore, this study has been designed to compare the effects of early moderate intensity walking on walking distance and quality of recovery, in two different groups of patients, with varying preoperative status. The study was set up as a 2-group, non-randomised comparative experimental design. 30 subjects, 27 males and 3 females, with a mean age of 55.2±6.7 years were included in the study. All the patients were mobilised early as per the early moderate intensity walking protocol. A six minute walk distance (6MWD) and a quality of recovery questionnaire were taken as outcome measures. Both groups showed significant improvement in 6MWD, but no statistical significant difference was found between the groups in improvement of 6MWD. Quality of recovery was also similar between the groups. Results indicate that the early moderate intensity walking can be implemented even on high risk patients with no adverse clinical sequelae. Thus, the early moderate intensity walking can be prescribed safely even to high risk patients.

Abstract
Introduction In 2005 Elizabeth Parker and fellow researchers described the first case of Hyperthymestic Syndrome, a woman going by initials AJ. Thereafter, a handful more of such cases have emerged. Older descriptions of extraordinary memory in medical literature mainly considered semantic and working memories. Jorge Luis Borges in his 1930s short story ‘Funes, his Memory’ writes about his, presumably fictitious, encounter with a man named Ireno Funes who possessed an extraordinary memory and a knack for keeping track of briefest of passing moment. Among many qualities that Funes and AJ share are their extraordinary memories, obsession for keeping track of time, and their problems with abstraction. After describing his extraordinary memory, Borges says of Funes, ‘I suspect nevertheless, that he was not very good at thinking. To think is to ignore (or forget) differences, to generalize, to abstract.’ Similarly, AJ has been described to have impaired abstraction, hypothesis formation and conceptual shifting. Moreover, both Funes and AJ see their capability as a burden rather than a gift. “My memory, sir, is like a garbage heap.” Says Funes. Objectives A brief exploration of Jorge Luis Borges’ works in the context of autobiographical memory. Methods The comparisons between Borges’ description of his character’s autobiographical memory and findings of modern research techniques will be done qualitatively. Results Effort is made to undersatnd Borges philosophy in context of mordern memory research. Conclusions An in depth look into Borges’ philosohies linking perception of time, coding of memory, abstration and language can inform further line of research regarding autobiographical memory. Disclosure No significant relationships.

Abstract
Animal production has a key role in global economic development and food security. Ticks, specifically Rhipicephalus microplus cause substantial economic and health impacts on more than eighty percent of the world cattle population. Though synthetic acaricides play a major role in tick management, their injudicious usage has caused environmental pollution and also promote the establishment of multi-acaricide resistant tick populations which is a matter of great concern. To provide an effective tool for controlling these resistant ticks, the present work was aimed to develop safe and inexpensive antitick natural formulations. Our bioprospection studies of Ageratum conyzoides plant established it as a species potentially having strong acaricidal activity due to the presence of potent acaricidal phyto-chemicals. To develop a suitable antitick natural formulation, 41 samples/fractions/formulations were prepared from the dry powder of the whole aerial part of the A. conyzoides plant using different techniques and delivery matrices. The strongest antitick effect was recorded for formulation ACF6, which demonstrated 87 ± 6% mean mortality with 57 % inhibition of oviposition in treated female ticks. Ticks treated with the ACF6 formulation showed a significant (p < 0.001) reduction in cuticular protein (1.238 ± 0.01 mg/mL) as compared to control ticks (2.928 ± 0.01 mg/mL) but no significant difference in chitin content of treated ticks and control ticks was observed. The formulation was found safe in a rat model as no significant differences in biochemical and haematological parameters among treated and control rats were noted. Histopathological studies indicated no sign of hepatocellular necrosis and no significant changes in the weights of liver and spleen was recorded. The overall in vivo efficacy of the formulation was 85 % for experimentally infested cattle with direct mortality of more than 80 % within 96 h post-application. The lethal effect of the formulation was in the form of drying and dead ticks 1-2 d after application. The developed formulation has the potential to be adopted as an alternative tick control measure in an ecofriendly manner.

Abstract
Matrix Metalloproteinases (MMPs)-induced altered proteolysis of extracellular matrix proteins and basement membrane holds the key for tumor progression and metastasis. Matrix metalloproteinases-7 (Matrilysin), the smallest member of the MMP family also performs quite alike; thus serves as a potential candidate for anti-tumor immunotherapy. Conversely, being an endogenous tumor-associated antigen (TAA), targeting MMP-7 for immunization is challenging. But MMP-7-based xenovaccine can surmount the obstacle of poor immunogenicity and immunological tolerance, often encountered in TAA-based conventional vaccine for anti-tumor immunotherapy. This paves the way for investigating the potential of MMP-7-derived major histocompatibility complex (MHC)-binding peptides to elicit precise epitope-specific T-cell responses towards their possible inclusion in anti-tumor vaccine formulations. Perhaps it also ushers the path of achieving multiple epitope-based broad and universal cellular immunity. In current experiment, an immunoinformatics approach has been employed to identify the putative canine matrix matelloproteinases-7 (cMMP-7)-derived peptides with MHC class-I-binding motifs which can elicit potent antigen-specific immune responses in BALB/c mice. Immunization with the cMMP-7 DNA vaccine induced a strong CD8+ cytotoxic T lymphocytes (CTLs) and Th1- type response, with high level of gamma interferon (IFN-γ) production in BALB/c mice. The two identified putative MHC-I-binding nonameric peptides (Peptide32-40 and Peptide175-183) from cMMP-7 induced significant lymphocyte proliferation along with the production of IFN-γ from CD8+ T-cells in mice immunized with cMMP-7 DNA vaccine. The current observation has depicted the immunogenic potential of the two cMMP-7-derived nonapeptides for their possible exploitation in xenovaccine-mediated anti-tumor immunotherapy in mouse model.

Abstract
The development of the tumorigenesis and angiogenesis through proteolytic cleavage of extracellular matrix protein and basement membranes is promoted by Matrix metelloproteinases-7 (MMP-7). Consequently, MMP-7 is presumed as potential target for mammary cancer immunotherapy. However, MMP-7 is an endogenous tumor associated antigen (TAA); therefore, immunization is challenging. In current study, a potent anti-tumor immune response has been elicited through recombinant bivalent plasmid pVIVO2.IL18.cMMP7 which subside the highly metastatic 4 T1 cell line induced mammary tumors and efficiently negate the existing challenge of using MMP-7 as immunotherapeutic target. Balb/c mice were immunized with canine MMP-7 (cMMP-7) using interleukine-18 (IL-18), as an immunoadjuvant, to explore the potential of the combination regarding elicitation of a potent anti-tumor immune response. Mice vaccinated with pVIVO2.IL18.cMMP7 DNA plasmid reduced the tumor growth significantly along with augmentation of the immune response to fight against tumor antigen as depicted by substantial enrichment of CD4+ and CD8+ population in splenocytes, infiltration of immune system cells in tumor tissue and enhanced survival time of mice. Further, splenocyte supernatant examination of the cytokines revealed that Th1 cytokines (IFN-γ and IL-2) were remarkably up-regulated demonstrating the stimulation of cell-mediated immune response. Thus the current observations vividly portray that administration of xenogeneic MMP-7 DNA vaccine bypasses the tolerance barrier.

Abstract
Conglutinin, a liver synthesized versatile innate immune marker consisting C-type lectin domain belongs to collectin superfamily of proteins. The protein, first detected in bovine serum as soluble pattern recognition receptor (PRR) has wide range of antimicrobial activities. In the present study, open reading frame (ORF) encoding neck and carbohydrate recognition domain (NCRD) of goat conglutinin gene ligated to the vector pRSET-A was expressed in E. coli BL-21(pLys) cells. The 27 kDa recombinant protein (rGCGN) purified by single step Ni+2 -NTA affinity chromatography was found to cross-react with recombinant anti-buffalo conglutinin antibody raised in poultry. Further, it displayed calcium-dependant sugar binding activity towards yeast mannan and calcium-independent binding activity towards LPS. The mannan binding activity of rGCGN was inhibited in the presence of N-acetyl-glucosamine because of higher affinity towards this sugar. The recombinant protein was found to stimulate production of superoxide ions and hydrogen peroxide in goat neutrophils, which are instrumental in stimulating phagocytic activity of cells. When used as antigen in Sandwich ELISA, straight line (Y = 0.299x + 0.067, R2 = 0.997) was observed within the concentration range of 200-1000 ng/100 μl of rGCGN. Using this equation, the native conglutinin concentration in goat sera was estimated to be 0.5-7.5 μg/ml. The results indicated that prokaryotically expressed functionally active rGCGN can be used as antigen to assess native serum conglutinin levels in Sandwich ELISA and as immunomodulator in therapeutic applications to sequester unwanted immune complexes from the circulation.

Abstract
This experiment was conducted to study the effect of gradual replacement of dietary buffalo meat on the bone (BMB) with chicken carcass (CC) on nutrient utilization, serum cortisol, and total serum antioxidant profile of zoo-housed Indian leopard. Twelve adult leopards were randomly distributed into a replicated Latin square design comprising three treatments, three periods, four animals, and three sequences. Leopards in group T1 were fed normal zoo diet of BMB. On the basis of dry matter, 10% and 20% of BMB was replaced with CC in groups T2 and T3 , respectively. Each experimental period comprised 21 days. During each period, a digestion trial of 4-day collection period was conducted after an adaptation period of 17 days. On Day 21 of each experimental period, blood was collected from all the animals by puncturing the ventral coccygial vein. Intake and apparent digestibility of major nutrients were similar among the groups. Replacement of 20% BMB with addition of CC increased (p < 0.001) the calculated supply of I, niacin, and vitamin A. Carotenoid intake increased (p < 0.01) with increased level of CC in the diet. Serum concentration of cortisol decreased (p < 0.01) whereas serum concentration of total carotenoids increased (p < 0.001) with increased level of CC in the diet. Serum concentration of antioxidant enzymes increased (p < 0.001) with increased level of CC in the diet. It was concluded that replacement of 20% of BMB with CC increased antioxidant profile. This may reduce oxidative stress in zoo-housed Indian leopards without any adverse effect on nutrient utilization.

Abstract
The non-steroidal anti-inflammatory drug (NSAID) diclofenac, known to cause hyperuricemia and concomitant visceral gout in Gyps vultures is suggested to be a result of interference with renal uric acid excretion. Three species of Gyps vultures are on the verge of extinction due to nephrotoxic veterinary diclofenac having entered the food chain, notwithstanding the fact that the toxicity of different avian species to the NSAIDs like diclofenac varies. The multidrug resistance protein 4 (MRP4), an organic anion transporter in birds has unique role in unidirectional efflux of urate into proximal renal tubular lumen for excretion and maintenance of homeostasis. We characterized MRP4 channel at molecular level to predict its structural based ligand binding activity in Gallus domesticus (Indian domestic chicken) and Gyps himalayensis (Himalayan griffon vulture). MRP4 gene was amplified using reverse transcribed cDNA from renal tissue sample in overlapping fragments. The obtained amplicons were cloned, sequenced, assembled and analyzed. Multiple alignment and blast analysis revealed point variations and presence of additional stretch of 57 bp towards the 3' end which was confirmed in Real time PCR. Predicted MRP4 polypeptides revealed presence of characteristic 12 transmembrane helices (TMH) with two nucleotide binding domains (NBD). Additional 19 amino acids in transcript variant was found to be localized in NBD2 that might influence the transporter function. The homology modeling and pocket identification throws ample light on varying transport efficacy and paves the way for depicting its role of these amino acids in effect of diclofenac on urate transport in further studies.

Abstract
Excessive fluoride intoxication plays an important role in the development of dental, skeletal and non-skeletal fluorosis. The aim of this study was to ascertain the toxic effect of excessive fluoride ingestion on the level of hydroxyproline and expression of type 1 collagen gene in rat bone and its amelioration by supplementation with Tamarindus indica fruit pulp extract. Forty albino rats were randomly assigned to four groups. The first group served as control and received only tap water. The second group received sodium fluoride (200 ppm) through drinking water. The third group received T. indica fruit pulp extract (200 mg/kg body weight) alone and the fourth group received the T. indica fruit pulp extract (200 mg/kg body weight) along with fluorinated drinking water (200 ppm) daily by gavage for a period of 90 days. The level of hydroxyproline and expression of type 1 collagen gene using quantitative real time PCR in the tibia bone decreased significantly with continuous exposure to sodium fluoride. Co-administration of T. indica fruit pulp extract during exposure to fluoride through drinking water restored the level of calcium, phosphorus and alkaline phosphatase in serum and the concentration of hydroxyproline in urine. It increased the level of hydroxyproline and expression of type 1 collagen gene in the tibia as compared to untreated fluoride-exposed rats. It is concluded that T. indica fruit pulp extract has an ameliorative potential to protect the bone from fluoride induced collagen damage.

Abstract
INTRODUCTION To audit the survival outcomes and loco-regional control in muscle invasive urinary bladder cancer patients treated with external beam radiation therapy (RT). MATERIALS AND METHODS From November 2008 through December 2011, 50 consecutively diagnosed muscle invasive urinary bladder carcinoma (T2-4a N0-2, M0) patients were included in this retrospective study. All these patients received external beam RT to a median dose of 60 Gy (range 30-66 Gy), and were not suitable for radical surgery due to patients' preference or medical comorbidities. A stepwise procedure using proportional hazard regression was used to identify prognostic factors with respect to survival. RESULTS Completion trans-urethral resection of bladder tumor was done in 38 (76%) patients of the cohort and 47 (94%) had transitional cell carcinoma on histopathology. Clinical stage T2 was diagnosed in 40 (80%) patients. The median follow-up for the entire cohort was 14 ± 8.9 months (range 1-36 months). In conclusion, 24 patients (48%) were free of disease, 5 patients (10%) had residual disease, and 13 patients (26%) had died of disease. Two-year and 3 year overall survival of intact bladder for the entire cohort was 58% and 43.6%, respectively. Cox regression modeling strongly suggested clinical stage (P = 0.01) and RT dose (P = 0.001) as being predictors for overall survival. CONCLUSION RT shows reliable outcomes and excellent compliance in this advanced disease. Prescribing a higher RT dose could potentially correlate to better intact bladder control rates while maintaining good quality of life in selected patients.

Abstract
Bovine herpesvirus-1 (BoHV-1) is an important viral pathogen causing significant economic losses to the cattle industry. Glycoprotein E-deleted marker vaccines form the basis for BoHV-1 control programs widely, wherein detection and differentiation of wild-type and gE-deleted vaccine strains is of crucial importance for proper disease management. In the present study, we report an EvaGreen-based multiplex real-time polymerase chain reaction (EGRT-PCR) assay for rapid differentiation of wild-type and glycoprotein E-deleted strains of BoHV-1. The EGRT-PCR assay could simultaneously detect two viral genes (glycoprotein B and E) and an internal positive control gene (bovine growth hormone- bGH), in a single-tube reaction. The analytical sensitivity of the EGRT-PCR assay was as little as 10 copies of the BoHV-1 DNA per reaction. The modified real-time PCR assay could successfully differentiate wild-type and gE-deleted BoHV-1 strains based on gene specific melting temperatures (Tm) peaks. Our results have shown that the EGRT-PCR developed in this study might prove to be a promising tool in disease management by enabling rapid differentiation of wild-type and gE-deleted strains of BoHV-1.

Abstract
COX-2 inhibitors exhibit anticancer effects in various cancer models but due to the adverse side effects associated with these inhibitors, targeting molecules downstream of COX-2 (such as mPGES-1) has been suggested. Even after calls for mPGES-1 inhibitor design, to date there are only a few published inhibitors targeting the enzyme and displaying anticancer activity. In the present study, we have deployed both ligand and structure-based drug design approaches to hunt novel drug-like candidates as mPGES-1 inhibitors. Fifty-four compounds with tested mPGES-1 inhibitory value were used to develop a model with four pharmacophoric features. 3D-QSAR studies were undertaken to check the robustness of the model. Statistical parameters such as r2 = 0.9924, q2 = 0.5761 and F test = 1139.7 indicated significant predictive ability of the proposed model. Our QSAR model exhibits sites where a hydrogen bond donor, hydrophobic group and the aromatic ring can be substituted so as to enhance the efficacy of the inhibitor. Furthermore, we used our validated pharmacophore model as a three-dimensional query to screen the FDA-approved Lopac database. Finally, five compounds were selected as potent mPGES-1 inhibitors on the basis of their docking energy and pharmacokinetic properties such as ADME and Lipinski rule of five.

Abstract
In order to study the effect of feeding graded levels of green vegetables on egg production performance and egg yolk antioxidant status, 27 female golden pheasants (GP) were randomly distributed into three groups of nine each in an experiment based on completely randomized design. The diets of the birds in groups T1 , T2 and T3 contained 1.4%, 2.7% and 5.0% of green vegetables respectively. Feeding of experimental diets started on 12th February (day 1) and was continued till 30 June 2012. Average number of eggs laid and egg mass produced by the hens in group T3 was higher (p < 0.004) than those of T1 and T2 . Hen day egg production was lowest (p < 0.001) in group T1 . Roche yolk colour score was highest (p < 0.01) in T3 followed by T2 and was lowest in T1 . Other external and internal egg quality parameters were similar among the groups. Total antioxidant capacity (TAC) of egg yolk was higher (p < 0.04) in group T3 as compared to other two groups. Egg yolk concentration of total carotenoids, β-carotene, total sulfhydryl, protein-bound sulfhydryl and non-protein-bound sulfhydryl was higher (p < 0.05), whereas concentration of malondialdehyde was lower (p < 0.024) in group T3 as compared to other two groups. Excreta concentration of corticosterone was highest (p < 0.012) in T1 , followed by T2 , and was lowest in T3 . Egg yolk concentration of TAC and TSH was positively and that of malondialdehyde was negatively correlated with carotenoids intake. Excreta concentration of corticosterone was negatively correlated with carotenoids intake. It was concluded that incorporation of green vegetables in the diet at 5% on dry matter basis would improve egg production, egg yolk antioxidant status and the ability of the captive GP to combat stress.

Abstract
This experiment was conducted to evaluate the effects of feeding different levels of green forages on feed consumption, nutrient and mineral utilization in Golden pheasants (GP). Twenty-seven female GP (BW 617-635 g) were randomly distributed into three groups of nine birds each in an experiment based on completely randomized design (CRD). Birds in group T1 were fed a conventional zoo diet containing 1.4% green forages; however, the diets of the birds in groups T2 and T3 contained 2.7% and 5.0% of green forages, respectively. Intake of total carotenoids increased with increased level of green forages in the diet. Apparent retention of N, Ca, and Zn was higher in GP laying hens fed diet containing 5.0% green forages as compared to those fed conventional diet containing 1.4% green forages. Results of the present study indicate that inclusion of 5% green forage in the diet of GP would improve the utilization of N, Ca, and Zn without any adverse effect on intake and utilization of other nutrients. Data related to nutrient intake, basal endogenous losses (BEL) and coefficient of retention (COR) of N, Ca, P, Mg, Fe, Cu, Mn, and Zn are novel and may be of use for future research.

Abstract
Background Recent data suggest that hypertension is a significant public health problem in India. The success strategies for hypertension management depend upon clients' awareness on hypertension and its self-management practices. Objective To determine awareness, self-management practices and compliance with treatment among hypertensive patients. Method This cross-sectional study was done in January 2012 at four health centres in Mangalore. All confirmed cases of hypertension attending the outpatient department were interviewed using a semi-structured interview schedule. Result Majority (58.7%) of the 315 participants were of the age group 41 to 60 years and majority (53.6%) were males. Most patients (69.5%) were educated up to high school level. The awareness level about hypertension was average or good in majority (52.4%) of the participants. Self-management practices were found to be average or good among 60.6% cases. Good compliance with treatment was seen in 78.7% cases and blood pressure was in control in 72.4% cases. Quality of self-management practices was found to influence control of blood pressure (p=0.021). Awareness, self-management practices and compliance were found to be significantly poor among aged (above 50 years), males, less educated, unemployed, unskilled or retired patients. Conclusion Awareness on hypertension and self-management practices were average or above among majority of the studied population. However this study identified groups who need to be better educated and further monitored to achieve universal blood pressure control among hypertensive population during the routine health care services in this settings.

Abstract
Several pathogens including Brucella spp. are shed in semen of infected bulls and can be transmitted to cows through contaminated semen during artificial insemination. The present study reports omp2a and bcsp31 gene based loop-mediated isothermal amplification (LAMP) assays for detection of Brucella genomic DNA in semen from infected bulls. The positive results could be interpreted visually by change in colour of reaction mixture containing hydroxyl naphthol blue (HNB) dye from violet to sky blue. LAMP assays based on omp2a and bcsp31 could detect as little as 10 and 100 fg of B. abortus S19 genomic DNA, respectively. Sensitivity of omp2a and bcsp31 LAMP assays for direct detection of organisms in bovine semen was 2.28 × 10(1) CFU and 2.28 × 10(2) CFU of B. abortus S19 in spiked bovine semen, respectively. The omp2a LAMP assay was found equally sensitive to TaqMan probe based real-time PCR and 100 times more sensitive than conventional PCR in identifying Brucella in spiked semen. The diagnostic applicability of the omp2a LAMP assay was evaluated with seventy-nine bovine semen samples and results were re-evaluated through TaqMan probe based real-time PCR and conventional PCR. Taken together, the omp2a LAMP assay is easy to perform, rapid and sensitive in diagnosis of Brucella spp. in bovine semen.

Abstract
This experiment was conducted to study the effect of feeding graded levels of dietary crude protein (CP) on serum biochemical profile of Lady Amherst's pheasants (LAP). Eighteen male LAP were randomly distributed into three groups of six each in an experiment based on completely randomized design. The CP content of the diets was 13.4%, 16.5%, and 19.1%, in groups I, II, and III, respectively. Serum concentrations of uric acid was lowest (P < 0.05) in group I. Relationship between serum concentration of uric acid and nitrogen intake was linear (R(2) = 0.39, P < 0.01). Concentrations of other serum metabolites and enzymes were similar among the groups. Serum concentration of triiodothyronine (T3 ) was highest (P < 0.05) in group I, followed by groups II and III. Total antioxidant capacity (TAC) of serum was lower (P < 0.007), whereas serum concentration of malondialdehyde (MDA) was higher (P < 0.001) in group I as compared to groups II and III. Regression of serum concentration of TAC (R(2) = 0.74, P < 0.01) and MDA (R(2) = 0.39, P < 0.05) was polynomial. Heterophil to lymphocyte ratio was higher (P < 0.007) in group I as compared to groups II and III. Relationship between H/L ratio and nitrogen intake was polynomial (R(2) = 0.69, P < 0.05). Cell mediated immune response measured as foot web index was similar among the groups. Based upon the results, it was concluded that a diet containing 16.5% crude protein would be optimum for improving antioxidant defense and the ability of Lady Amherst's pheasant to combat stress.

Abstract
Somatic cell nuclear transfer (SCNT) is a promising technology in buffalo for multiplication of elite animals, species conservation, and production of transgenic embryos for therapeutic applications. However, the cloning efficiency obtained in this species is very low, which might be due to improper reprogramming of donor cells after SCNT. Treatment of donor cells or fused embryos or both with epigenetic modifiers might be a suitable approach to improve the ability of donor cells to be reprogrammed. The present study was aimed at examining the effects of treatment of donor cells (24 h before SCNT) or fused embryos (10 h post-electrofusion) or both with 50 nM TSA + 7.5 nM 5-aza-dC on the developmental competence, quality, and epigenetic status of buffalo embryos produced by hand-made cloning (HMC) as described earlier (Saini et al. 2014 Reprod. Fertil. Dev. doi: 10.1071/RD14176). The percentage data were analysed using SYSTAT 12.0 (SPSS Inc., Chicago, IL, USA) after arcsine transformation. Differences between means were analysed by one-way ANOVA followed by Fisher’s least significant difference test. The blastocyst rate was significantly higher (P < 0.05) and the apoptotic index was significantly lower (P < 0.05) in embryos produced from donor cells or fused embryos or both treated with TSA + 5-aza-dC than that of controls (Table 1). However, the cleavage rate and the total cell number were not significantly different among all the groups. The global level of H3K18ac, examined by immunofluorescence staining, was higher (P < 0.05) and that of H3K27me3 was lower (P < 0.01) in blastocysts produced from donor cells or fused embryos or both treated with TSA + 5-aza-dC than that of controls. These results show that treatment of donor cells, fused embryos, or both with TSA + 5-aza-dC improves the developmental competence and quality, and alters the epigenetic status of buffalo embryos produced by HMC. However, the effects of treatment with these epigenetic modifiers on the pregnancy rate require further studies.

Abstract
We examined the effects of treating buffalo skin fibroblast donor cells with trichostatin A (TSA), a histone deacetylase (HDAC) inhibitor, and 5-aza-2′-deoxycytidine (5azadC), a DNA methyltransferase (DNMT) inhibitor, on the cells and embryos produced by hand-made cloning. Treatment of donor cells with TSA or 5azadC resulted in altered expression levels of the HDAC1, DNMT1, DNMT3a, P53, CASPASE3 and CASPASE9 genes and global levels of acetylation of lysine at position 9 or 14 in histone 3 (H3K9/14ac), acetylation of lysine at position 5 in histone 4 (H4K5ac), acetylation of lysine at position 18 in histone 3 (H3K18ac) and tri-methylation of lysine at position 27 in histone 3 (H3K27me3). Moreover, global levels of DNA methylation and activity of DNMT1 and HDAC1 were decreased, while global acetylation of H3 and H3K9 was significantly increased in comparison to untreated cells. Simultaneous treatment of donor cells with TSA (50 nM) and 5azadC (7.5 nM) resulted in higher in vitro development to the blastocyst stage, reduction of the apoptotic index and the global level of H3K27 me3 and altered expression levels of HDAC1, P53, CASPASE3, CASPASE9 and DNMT3a in cloned blastocysts. Transfer of cloned embryos produced with donor cells treated with TSA led to the birth of a calf that survived for 21 days. These results show that treatment of buffalo donor cells with TSA and 5azadC improved developmental competence and quality of cloned embryos and altered their epigenetic status and gene expression, and that these beneficial effects were mediated by a reduction in DNA and histone methylation and an increase in histone acetylation in donor cells.

Abstract
In order to find out the optimum level of crude protein (CP) in the diet of captive Lady Amherst's pheasants (LAP) on molt, 18 male birds were randomly distributed into three groups of six each in an experiment based on completely randomized block design. The CP content of the diets of birds in groups I, II, and III was 13.4, 16.5, and 19.1%, respectively. Intake and apparent balance of nitrogen increased linearly (P < 0.001) as CP content of the diet increased. Intake and utilization of energy, calcium, and phosphorous were similar among groups. Body mass change and growth rate of feathers were significantly (P < 0.01) lower in group I as compared to groups II and III. There was a positive co-relationship between ME intake and change in body weight (R(2) = 0.89, F = 126.4, P < 0.001). Regression analysis indicates that LAP can maintain body mass when ME supply is 122.2 Kcal/kg BW(0.75)/d. Linear relationships between intake and apparent retention of N, Ca, and P as expressed on mg/kg BW(0.75)/d were all significant. Apparent nitrogen retention, and mean feather growth rate was lower in birds fed diet containing 13.4% CP. Feeding of the diets containing 16.5% CP resulted in improved retention of nitrogen, and mean feather growth rate. Further increase in dietary concentration of CP to 19.1% showed no further improvement. It was concluded that a diet containing 16.5% CP would be optimum for Lady Amherst's pheasants during molt.

Abstract
Veterinary use of the non-steroidal anti-inflammatory drug diclofenac on domesticated ungulates caused populations of resident Gyps vultures in the Indian sub-continent to collapse. The birds died when they fed on carrion from treated animals. Veterinary diclofenac was banned in 2006 and meloxicam was advocated as a 'vulture-safe' alternative. We examine the effectiveness of the 2006 ban, whether meloxicam has replaced diclofenac, and the impact of these changes on vultures. Drug residue data from liver samples collected from ungulate carcasses in India since 2004 demonstrate that the prevalence of diclofenac in carcasses in 2009 was half of that before the ban and meloxicam prevalence increased by 44%. The expected vulture death rate from diclofenac per meal in 2009 was one-third of that before the ban. Surveys at veterinary clinics show that diclofenac use in India began in 1994, coinciding with the onset of rapid Gyps declines ascertained from measured rates of declines. Our study shows that one pharmaceutical product has had a devastating impact on Asia's vultures. Large-scale research and survey were needed to detect, diagnose and quantify the problem and measure the response to remedial actions. Given these difficulties, other effects of pharmaceuticals in the environment may remain undetected.

Abstract
Following IVF, embryos which cleave early have been shown to have higher developmental competence and quality than those that cleave relatively later across many species. We investigated the effect of time of cleavage on the developmental competence, quality, epigenetic status and gene expression in buffalo embryos produced by handmade cloning (HMC). Following classification of embryos as early cleaving (EC) or late cleaving (LC) based on whether they had cleaved or not at 24 h post in vitro culture, 54% (164/303) were found to be EC and the rest to be LC. The blastocyst rate (58.1 ± 3.4 vs 36.9 ± 1.6%, p < 0.01) and the total cell number (285.5 ± 41.9 vs 141.4 ± 36.1, p < 0.05) were higher, whereas the apoptotic index (3.6 ± 0.6 vs 12.2 ± 1.7, p < 0.01) and the global level of H3K9ac and H3K27me3 were lower (p < 0.05) in the blastocysts produced from EC than in those produced from LC embryos. The relative transcript level of CASPASE3, CASPASE7, DNMT1, DNMT3a and CDX2 was higher (p < 0.05) and that of SOX2 was lower (p < 0.05) in blastocysts produced from LC than in those produced from EC embryos, whereas the expression level of CASPASE6, P53, P21, HDAC1, OCT4 and NANOG was not significantly different between the two groups. These results show that (i) following HMC, blastocysts produced from embryos that cleave early differ from those produced from late cleaving embryos in terms of epigenetic status and expression level of many important apoptosis-, pluripotency-, trophectoderm- and epigenetics-related genes, and (ii) EC embryos are superior to LC embryos in view of their higher developmental competence and quality.

Abstract
Cryopreservation of semen allows preservation of somatic cells, which can be used for the production of progeny through somatic cell nuclear transfer (SCNT). This approach could enable restoration of valuable high-genetic-merit progeny-tested bulls, which may be dead but the cryopreserved semen is available. We have successfully produced a live buffalo calf by SCNT using somatic cells isolated from >10 year old frozen semen (Selokar et al. 2014 PLoS One 9, e90755). However, the calf survived only for 12 h, which indicates faulty reprogramming of these cells. The present study was, therefore, carried out to study the effect of treatment with trichostatin A (TSA), an epigenetic modifier, on reprogramming of these cells. Production of cloned embryos and determination of quality and level of epigenetic markers in blastocysts were performed according to the methods described previously (Selokar et al. 2014 PLoS One 9, e90755). To examine the effects of TSA (0, 50, and 75 nM), 10 separate experiments were performed on 125, 175, and 207 reconstructed embryos, respectively. The percentage data were analysed using SYSTAT 12.0 (SPSS Inc., Chicago, IL, USA) after arcsine transformation. Differences between means were analysed by one-way ANOVA followed by Fisher's least significant difference test for significance at P < 0.05. When the reconstructed buffalo embryos produced by hand-made clones were treated with 0, 50, or 75 nM TSA post-electrofusion for 10 h, the cleavage percentage (100.0 ± 0, 94.5 ± 2.3, and 96.1 ± 1.2, respectively) and blastocyst percentage (50.6 ± 2.3, 48.4 ± 2.7, and 48.1 ± 2.6, respectively), total cell number (274.9 ± 17.4, 289.1 ± 30.1, and 317.0 ± 24.2, respectively), and apoptotic index (3.4 ± 0.9, 4.5 ± 1.4, and 5.6 ± 0.7, respectively) in Day 8 blastocysts were not significantly different among different groups. The TSA treatment increased (P < 0.05) the global level of H4K5ac but not that of H3K18a in embryos treated with 50 or 75 nM TSA compared with that in controls. In contrast, the level of H3K27me3 was significantly lower (P < 0.05) in cloned embryos treated with 75 nM TSA than in embryos treated with 50 nM TSA or controls. The ultimate test of the reprogramming potential of any donor cell type is its ability to produce live offspring. To examine the in vivo developmental potential of the 0, 50, or 75 nM TSA treated embryos, we transferred Day 8 blastocysts, 2 each to 5, 6, and 5 recipients, respectively, which resulted in 2 pregnancies from 75 nM TSA treated embryos. However, one pregnancy was aborted in the first trimester and the other in the third trimester. In conclusion, TSA treatment of reconstructed embryos produced from semen-derived somatic cells alters their epigenetic status but does not improve the live birth rate. We are currently optimizing an effective strategy to improve the cloning efficiency of semen-derived somatic cells.
