Cells were washed after 48 hr and lysed for 30 min at 4° in radioimmunoprecipitation assay buffer [1% Triton X-100 (v/v), 0·5% sodium deoxycholate (w/v), 0·1% SDS] containing protease inhibitor cocktail (Sigma-Aldrich). Cell debris was spun down at 15 600 g

for 15 min. Precipitates were removed and aliquots of cell lysates were diluted in SDS sample buffer, boiled at 100° for 3 min, spun down, and applied to precast 10% acrylamide Tris–glycine gels at 40 g protein/lane and run at 150 V for 1 hr. Samples were transferred to nitrocellulose membrane (BioRad) at 100 V for 1 hr. Membranes were probed using rabbit anti-mouse Arg I polyclonal antibody (Santa Cruz Biotechnology, HM781-36B order Santa Cruz, CA) and rabbit anti-mouse iNOS (NOS2) polyclonal antibody

(BD Biosciences) at a 1 : 500 and 1 : 2000 dilutions, respectively, followed by peroxidase-conjugated anti-rabbit antibody (Sigma-Aldrich) at a 1 : 1000 dilution. Bands were visualized using a chemiluminescence reaction. Splenocytes were prepared from naive mice, and enriched for CD90.2+ cells (90% by FACS analysis) using anti-FITC-coated magnetic beads (MACS; Miltenyi Biotec, Bergisch Gladbach, Germany) after incubation with FITC-conjugated anti-CD90.2 mAb. Peritoneal cells were enriched for F4/80+ Mφs (85% by FACS analysis) using anti-FITC-coated KU-60019 magnetic beads (MACS; Miltenyi Biotec) after incubation with FITC-conjugated anti-F4/80 mAb. The T-cell proliferative response was evaluated after co-culturing CD90.2+ spleen cells (2 × 105 cells/200 μl/well) with F4/80+ peritoneal cells in flat-bottom microwell tissue Oxymatrine culture

plates at different T-cell/ Mφ ratios (2 : 1, 5 : 1, 10 : 1 and 20 : 1) in the presence of 2.5 μg/ml concanavalin A (Con A; Sigma-Aldrich). The presence of naive Mφs increased proliferation of CD90.2+ T cells and the most effective Mφ-to-T-cell ratio was 1 : 10 (data not shown). The PD-1/PD-Ls pathway blockade on the proliferative response was evaluated after co-culturing CD90.2+ spleen cells (2 × 105 cells/200 μl/well) with infected or non-infected F4/80+ peritoneal cells in flat-bottom microwell tissue culture plates treated with 5 μg/ml isotype control, anti-PD-1, anti-PD-L1 or anti-PD-L2 in the presence of 2.5 μg/ml Con A (Sigma-Aldrich). Cultures were maintained at 37° in a humidified 5% CO2 atmosphere for 3 days and 0·5 μCi/well [methyl-3H] thymidine (Amersham, Chicago, IL) was added for the last 18 hr of culture. Cells were collected with a cell harvester (Cambridge Technology, Watertown, MA) and processed for standard liquid scintillation counting using a counter from Beckman Instruments (Fullerton, CA). Values are represented as counts per minute from triplicate wells. The T. cruzi-infected and non-infected peritoneal cells were obtained and single cell suspensions were prepared in RPMI-1640 supplemented as above.

Repetition of ATCMR promotes chronic change of allograft tissue,

Repetition of ATCMR promotes chronic change of allograft tissue, which results

in the poor allograft outcome. Therefore, our results suggest that the IL-17-dominant state may involve in the development of chronic change by repeat ATCMR. We investigated C4d positivity to evaluate whether the FOXP3/IL-17 ratio is associated with humoral immunity. Our results showed that C4d positivity and the coexistence of acute antibody-mediated rejection did not differ significantly between click here the two groups. In addition, glomerulopathy or vasculopathy, which is associated with humoral immunity, was not different between the two groups.31–33 These findings suggest that the impact of the Th17–Treg axis on humoral immunity is not as strong as its effect on T-cell-mediated immunity. The results of our study demonstrated that the ratio between Treg and IL-17-secreting

cell infiltration in the renal allograft represents the severity of ATCMR. But it is uncertain whether a similar ratio between these two cells is observed in peripheral blood mononuclear cells (PBMCs). In a previous report, significantly higher Treg infiltration in allograft tissue was observed even though its proportion in PBMCs was not elevated.34 It may be because the allograft is a more active site of immune stimulation than PBMCs. Therefore, it is possible that the ratio between Treg and IL-17-secreting cells in PBMCs PF 2341066 is different from that in allograft. Our study has some limitations. First, this study is retrospective and non-randomized. For example, the proportion of basiliximab induction therapy was significantly

higher in the FOXP3 high group. However, basiliximab induction was not a significant prognostic factor for allograft outcome in this study. In addition, the FOXP3/IL-17 ratio did not differ significantly between the patients who took basiliximab induction and the patients who did not (data not shown). The above findings suggest that basiliximab induction did not have a significant effect on the development of an IL-17-secreting cell or FOXP3+ Treg dominant condition, and allograft outcome oxyclozanide after ATCMR. Second, the microenvironment, which is associated with the IL-17-driven or the FOXP3+ Treg-driven condition, was not assessed. Therefore, randomized controlled trials investigating the inflammatory cytokines associated with IL-17-producing cell development, such as IL-6, IL-21 and tumour necrosis factor-α, may help to understand clearly the underlying mechanisms that drive the IL-17 high or FOXP3 high condition.35 In summary, it is helpful to assess IL-17-secreting cell infiltration combined with FOXP3+ Treg in predicting the clinical outcome after ATCMR. The ratio between FOXP3 and IL-17 was closely associated with allograft function and the severity of tissue injury. Their ratio was also associated with the clinical outcome of ATCMR and long-term allograft survival.

“Overactive bladder syndrome (OAB) is highly prevalent bla

“Overactive bladder syndrome (OAB) is highly prevalent bladder disorder in men and women. About 10–15% of the population suffers from urgency frequency with or without urgency urinary incontinence. It is estimated that 50–75% of patients with OAB may have urodynamic detrusor overactivity (DO). Urodynamic study invasive and most of the OAB patients might not accept it as a routine assessment. Therefore, a more objective and non-invasive test for diagnosis and assessing DO from OAB patients is needed. Recently, urinary nerve growth factor (NGF) has gained great interest in detecting DO in patients with OAB.

Urinary NGF level was found to increase in OAB and urodynamic DO. Urinary NGF levels correlated with severity of OAB symptoms. Patients with either idiopathic or neurogenic DO may have increased urinary NGF levels. Urinary NGF levels have been shown to decrease in patients CAL 101 with

ACP-196 concentration patients with OAB and DO who have been well treated with antimuscarinics or botulinum toxin injection, but not in those with persistent OAB after treatment. Not all patients with OAB can have an elevated urinary NGF level; it may also be increased in patients with interstitial cystitis/painful bladder syndrome and other lower urinary tract diseases, suggesting urinary NGF expression could be a product of bladder inflammation and a limited specificity of urinary NGF for diagnosing DO. The source of urinary NGF has not yet been fully explored yet. Nevertheless, urinary NGF level is likely to be a promising biomarker for diagnosis of DO from OAB patients, to monitor therapeutic outcome and predict disease progression. “
“Objectives: To examine the efficacy, safety, and dose response of tadalafil once daily in Japanese men with lower urinary tract

symptoms suggestive of benign prostatic hyperplasia (BPH-LUTS). Methods: Men ≥45 years with moderate-to-severe BPH-LUTS were randomized to once-daily placebo (N = 140), tadalafil 2.5 mg (N = 142), or tadalafil 5.0 Palbociclib datasheet mg (N = 140), in a 12-week double-blind phase, followed by a 42-week, tadalafil 5.0 mg open-label extension (OLE) phase (N = 394). The primary outcome was total International Prostate Symptom Score (IPSS) change from baseline to last available observation in the double-blind phase. Results: The least squares (LS) mean difference between placebo and tadalafil in total IPSS change from baseline was −0.7 (P = 0.201) and −1.1 (P = 0.062) for tadalafil 2.5 and 5 mg, respectively (ANCOVA; a dose-dependent improvement in placebo-adjusted total IPSS for tadalafil 5 mg versus 2.5 mg of 57%). Repeated-measures analyses identified a significant total IPSS change for tadalafil 5 mg (LS mean difference between placebo and tadalafil 5 mg: −1.2; P = 0.035), but not tadalafil 2.5 mg, at week 12.

Method of study  In the first experiment, genes and pathways whos

Method of study  In the first experiment, genes and pathways whose expression were regulated by CSF2 were identified by microarray analysis. Embryos were treated AZD0530 manufacturer with 10 ng/ml CSF2 or vehicle at Day 5 after insemination; morulae were selected for microarray analysis at Day 6. In a second experiment, antiapoptotic

effects of CSF2 were determined. Embryos were treated with CSF2 or vehicle at Day 5. On Day 6 (24 h after treatment), morulae were cultured for 15 h at either 42°C (a temperature that induces apoptosis) or 38.5°C (cow body temperature). Results  In the first experiment, a total of 214 genes were differentially regulated and 160 of these could be annotated (67 upregulated genes and 93 downregulated genes). Differentially expressed genes could be placed in 13 biological process ontologies in four functional groups (development and differentiation process, cell communication, apoptosis and cell adhesion). Antiapoptotic effects of CSF2 were confirmed in the second experiment because the magnitude of the increase in TUNEL positive cells caused by heat shock was reduced by CSF2. Conclusion  CSF2 blocks apoptosis in bovine embryos through actions associated with regulation of genes controlling apoptosis. “
“Pregnancy still represents one of the most fascinating paradoxical phenomena in science. Immediately after conception, the maternal immune system is challenged by the

presence of foreign paternal antigens in the semen. This triggers see more mechanisms of recognition and tolerance that all together allow the embryo to implant and later the fetus to develop. Tolerance mechanisms to maintain pregnancy are of special Clomifene interest as they defy the classical immunology rules. Several cell types, soluble factors, and immune regulatory molecules have been proposed to contribute to fetal tolerance. Within these, regulatory T cells (Treg) are one of the most studied immune cell populations lately. They are reportedly involved in fetal acceptance.

Here, we summarize several aspects of Treg biology in normal and pathologic pregnancies focusing on Treg frequencies, subtypes, antigen specificity, and activity as well as on factors influencing Treg generation, recruitment, and function. This review also highlights the contribution of fetal Treg in tolerance induction and addresses the role of Treg in autoimmune diseases and infections during gestation. Finally, the potential of Treg as a predictive marker for the success of assisted reproductive techniques and for therapeutic interventions is discussed. “
“Retinoic acid or vitamin A is important for an extensive range of biological processes, including immunomodulatory functions, however, its role in gastrointestinal parasite infections is not yet clear. Despite this, parasite infected individuals are often supplemented with vitamin A, given the co-localised prevalence of parasitic infections and vitamin deficiencies.

The presence of traditional and nontraditional risk factors assoc

The presence of traditional and nontraditional risk factors associated with CKD may be responsible, at least partly, for the development of CVD. Additionally, reduced kidney function may be a marker of the severity of either diagnosed or undiagnosed vascular disease. Finally, patients with CKD may not receive sufficient therapy to prevent CVD, including medications such as aspirin, beta-blockers, angiotensin-converting enzyme (ACE) inhibitors, and diagnostic and therapeutic procedures. Atrial

fibrillation (AF) is common clinically significant arrhythmia in patients with hypertension. AF is significant risk factor for ischemic stroke and heart failure events. In 1118 consecutive hypertensive patients of our hospital, the new-onset AF was found in 1.1% per year during follow-up period (4.5 year). CKD was associated Imatinib with an increased risk of new-onset AF, and the impact of CKD Autophagy animal study on the incidence of AF was independent of left ventricular hypertrophy and left atrial dilation. In particular, advanced stages of CKD were closely related to the increasing occurrence of AF. Therefore, in managing hypertensive patients, it may be important to prevent the progression of renal dysfunction in prevention of the occurrence of AF. Clinical markers of renal damage such as proteinuria and reduced GFR were revealed as strong risk factors for CVD. Recently, the attention to markers of subclinical renal damage Thiamet G has been growing because of

their predictive value of cardiovascular outcome. Renal Doppler ultrasonography has been used to explore the capacity of resistive index (RI) calculated from blood flow velocity in the prediction of the renal outcome in patients with hypertension, diabetes and CKD. In 426 consecutive

hypertensive patients of our hospital, the increased RI on the baseline Doppler ultrasonography was associated with an increased risk of cardiovascular and renal outcomes and the combination of high RI and low GFR was a powerful predictor of poor outcome in hypertensive patients. RI evaluation will complement screening for cardiovascular risk. In conclusion, CKD markers such as proteinuria, GFR and RI were useful predictor for CVD outcomes. Therefore, the evaluation and control of CKD markers may be important to prevent CVD.

All patients showed a complete response to anti-rejection treatme

All patients showed a complete response to anti-rejection treatment. Additional patient characteristics are presented in Table 1. None of the patients had active BK virus (BKV) or CMV infection in the time-period following transplantation until or during

their PF-02341066 solubility dmso acute rejection episode. Responder peripheral blood mononuclear cells (PBMC) were labelled with CFSE (Molecular Probes Europe BV, Leiden, the Netherlands), as described previously [22], and cultured with irradiated donor cells or with irradiated third-party cells in a one-to-one ratio. The precursor frequency was calculated as follows: [Σn>=1(Pn/2n)]/[Σn>=0(Pn/2n)], where ‘n’ is the division number that cells have passed through and ‘Pn’ is the number of cells in division n [25] and equals the percentage of alloreactive cells at the start of the mixed lymphocyte reaction that participates in the alloresponse. Freshly thawed cells and cells obtained after 6

Selleck HDAC inhibitor days’ MLC were stained as follows: 500 000 PBMC were incubated with fluorescently labelled conjugated mAbs (at saturating concentrations) for 30 min at 4°C, protected from light. The necessary fluorochrome-conjugated antibodies were purchased from eBiosience, Inc. (San Diego, CA, USA), Becton Dickinson (BD) (San Jose, CA, USA) or Sanquin (Amsterdam, the Netherlands) Samples were measured using the FACS Canto flow cytometer from BD. Subsequent analysis was done using FlowJo version 8·8. The gating was performed using isotype controls. IFN-γ ELISPOT assay was performed as described previously in detail [26]. Briefly, 96-well

plates (Millipore, Eschborn, Germany) were first coated with a primary IFN-γ antibody (BD Pharmingen, Heidelberg, Germany) and left at 4°C overnight. Next, 3 × 105 responder PBMC and 3 × 105 donor or third-party T cell-depleted cells were incubated in triplicate wells. Phytohaemagglutinin (PHA) was used as a positive control and as a negative control we used autologous MLC, recipient cells alone and stimulator cells alone. After 24 h of incubation at 37°C, 5% CO2, plates were washed with phosphate-buffered saline (PBS) and PBS-Tween-20. Biotinylated during anti-IFN-γ antibody was added and incubated overnight at 4°C. Then, streptavidin–horseradish peroxidase conjugate (BD) was added for 2 h. After a final wash, plates were developed with 3-amino-9-ethylcarbazole. Results are presented as median values of ELISPOTs detected in triplicate wells containing responder PBMC plus donor stimulator cells after subtracting the response of wells with responder or donor cells only. After 6 days’ MLC, PBMC were stained with anti-IL-7Ra (CD127)-peridinin chlorophyll (PerCP)-cyanin 5·5 (Cy5·5), CD3-PE-Cy7 and CD8-PE-Alexa610 (all purchased from BD) and sorted in CFSE-negative, CD8+ IL-7Rα+ fraction and CFSE-negative CD8+ IL-7Rα- fraction using the Aria FACS (BD Biosciences).

Exosomes released from cancers contain oncoproteins and miRNAs wh

Exosomes released from cancers contain oncoproteins and miRNAs which may promote cancer progression. A novel technology which consists of immobilized affinity agents in the outer-capillary space of hollow-fibre plasma separator cartridges that integrate into standard dialysis

machines has been BYL719 devised. This technology is currently being evaluated for its efficacy for capturing exosomes secreted by cancer cell lines and present in biological fluids from cancer patients[106] and could potentially be applied to other situations such as atherosclerosis in which circulating microvesicles might have pathogenic roles. While there is an increasing appreciation of the existence and potential functions of exosomes and other vesicles, some very fundamental questions remain. Are there distinct cell-specific types or families of exosomes with well-defined sizes, cargos and differing functions? How is exosomal cargo modified? What are the physiological and pathological stimuli to their production, release and uptake? What are their physiological signalling roles in the circulation and urine? What receptors or other mechanisms define their target cells? What is the effect of renal FDA-approved Drug Library chemical structure function and disease

on the levels and nature of circulating and urinary exosomes? Addressing these questions should provide new insights in the intercellular communication mechanism and enable a more sophisticated translation of the use of exosomes as novel biomarkers and therapeutic intervention strategies. “
“Aim:  Haemodiafiltration (HDF) is the most efficient blood purification method and can remove a wide spectrum of solutes of different molecular weights (MW). The purpose of this study was to investigate whether the removed amounts of solutes, especially the larger molecules, could be

increased by changing the HDF filtration Proteasome inhibitor procedure. Methods:  A new first-half intensive HDF treatment (F-HDF) was designed, whereby convective clearance is intensively forced during the first half of a HDF session. We compared the removed amounts of solutes in the same group of nine patients treated by F-HDF, constant rate-replacing HDF (C-HDF) and a high-flux haemodialysis (HD). Results:  F-HDF can remove significantly larger amounts of α1-microglobulin (MG), molecular weight (MW) 33 000, compared with HD and C-HDF (30.1 ± 15.1 vs 12.4 ± 0.3, 15.0 ± 3.1 mg, P < 0.01). Regarding the removal amounts and clear space of β2MG, MW 11 800, there were no significant differences between the three treatment modalities. Regarding amounts of creatinine, urea nitrogen and phosphorus, there were no significant differences between the three treatment modalities.

ESID and focused AAAAI respondents differed in this regard in onl

ESID and focused AAAAI respondents differed in this regard in only two disease categories: IgAD and SCID. Only 28·1% of ESID respondents perceived moderate to extreme utility in prophylaxis in IgAD, whereas 54·4% of focused AAAAI respondents held this opinion (P = 0·002); again, this may be the result of different definitions of IgAD between the two groups [9,15]. In SCID, 78·7% of ESID compared to 55·3% of focused AAAAI CP-690550 ic50 respondents found moderate to extreme utility in prophylaxis for these patients (P = 0·002). The other statistically significant differences were between ESID and general AAAAI respondents across a wide range of fairly rare conditions (Fig. 5a, P < 0·05

for all comparisons), where the perceived utility of antibiotic prophylaxis was greater among ESID members. The use of rotating prophylactic antibiotics is also controversial, as there are no supporting

studies. More ESID respondents (58·7%) than focused AAAAI respondents (41·8%) reported that they do not rotate antibiotics (P = 0·043). Conversely, more AAAAI respondents overall would rotate the prophylactic antibiotic on a monthly basis compared with ESID respondents (focused P = 0·023, general P = 0·002). Why ESID members were less likely to rotate antibiotics when used as prophylaxis remains unclear, but represents an important direction for future interventional clinical research. There was little variability in the chosen interval for follow-up for healthy PID patients; all GW-572016 chemical structure Depsipeptide manufacturer three subgroups agreed that every 6 months was the most appropriate (Fig. 6a). ESID respondents more frequently recommended quarterly evaluations (35·7%) compared with the general AAAAI respondents (23·6%, P = 0·015), and were less likely to recommend annual follow-up (P = 0·021). The fact that clinical immunology has been a separate subspeciality in several countries in Europe may explain the trend towards more regular routine PID patient evaluations than in the United States, where immunology is combined most typically with a large allergy practice. The most striking difference across the entire questionnaire, however, arose when providers were asked to assess the risk

to their patients of reimbursement policies for IVIg therapies. Within the ESID respondents, there was a general trend towards no or slight perceived risk, whereas there was a strong concern among AAAAI respondents, with the majority reporting extreme or serious risk (Fig. 6b). While this is due probably to the differences in health-care models that exist between Europe and the United States, it underscores a need for the collection of clinical outcome data on newly diagnosed patients in both continents and standardized quality of life information for existing patients; these will enable health technology assessments to be made to inform payers – whether insurers or government agencies – and to ensure appropriate health-care provisions.

As vaccination of sheep with the H11 protein gives rise to protec

As vaccination of sheep with the H11 protein gives rise to protection and/or a reduction in worm burden after challenge infection (126), the authors investigated whether gene knock-down would have an effect on

worm development within the sheep host. Sheep infected with RNAi-treated larvae showed a 57% reduction in faecal egg count and 40% reduction in worm burden compared Cobimetinib to control dsRNA-treated larvae, providing evidence that the knock-down of a protective antigen mirrors the effect of vaccination (121). Thus, RNAi can potentially be utilized to elucidate gene function in vivo during actual infection, leading to the identification of crucial genes in parasite development and survival and parasite–host interaction. In conclusion, the susceptibility of parasitic nematodes to RNAi seems to be

dependent on how the trigger is delivered, the target gene, the life stage of the specific parasite and the presence of the RNAi machinery. Therefore, large-scale analysis and screening protocols might not be easily realized in nematodes but targeting genes at dsRNA accessible sites can be utilized to elucidate gene function in vivo. Therefore, RNAi has the potential to become a useful tool for the identification of vaccine candidates and drug targets. Transgenesis and RNAi have already made a tremendous impact on helminth research. Although the transgenesis techniques available today thus far have mainly been used to over-express reporter genes such as GFP and luciferase, they have also allowed analysis of the tissue-specific expression of parasite genes. In nematodes, we now see the emergence of functional

CP-673451 in vitro studies using constructs to interfere with the corresponding endogenous genes to study signal transduction pathways. Heritable transgenesis is within our grasp, and once achieved, it will open the door to the study of the effect of transgenes on infections. It will, for example, enable the examination MG-132 mouse of the activation of host immune responses, and to understand where, when and how such responses are initiated. Likewise, the development of gene trap vectors will give us a better understanding of the sets of genes that are active in particular life cycle stages. Gene silencing using RNAi is now well established in many parasitic helminths and has for the first time allowed the direct study of parasite gene function. Nevertheless, there is still an urgent need for the development of more robust transgenic technologies for use in parasitic helminths in the post-genomic era. The wealth of information made available from genome sequencing projects will undoubtedly translate into functional genomic studies in these organisms. Such studies will not only provide a deep understanding of the molecular biology of the parasite, but could ultimately be used for the identification of proteins that could be targeted with drugs or vaccines.

Two basic algorithms used during

applications of smoothin

Two basic algorithms used during

applications of smoothing filter include calculation of the so-called ‘Smoothed DB(biggest)’ (filter that reduces the series of box sizes by starting at the smallest box size and going only towards greater sizes than the previous) and ‘Smoothed DB(small)’ (filter that reduces the series of box sizes by starting at the largest size and going only towards smaller box sizes).[20] Although it is expected that smoothed DB(biggest) and smoothed DB(small) are closely correlated with Db, their calculation CH5424802 research buy may significantly increase the validity of the obtained Db results (assuming that all three dimensions change in the same way). Lacunarity (Λ) was calculated using the following formula: Grey level co-occurrence Vadimezan nmr matrix (GLCM) textural analysis of each chromatin structure was performed using ImageJ software and its texture analysis plugins developed by Julio E. Cabrera and updated by Toby C. Cornish.[21, 22] Calculation of GLCM features, angular second moment (ASM) and

inverse difference moment (IDM) was done according to the protocol first presented in the work of Haralick et al.:[23] As an addition to the experimental protocol, we tested the inter-rater reliability of fractal and GLCM analysis methods by determining Pearson’s correlation coefficient for each of the measured parameters. A sample of 100 randomly selected MDC nuclei were segmented and analyzed by two researchers (IP and JP). Values of Pearson correlation coefficient for interobserver agreement were 0.983 for DB, 0.989 for DB(small), 0.983

for DB(biggest), 0.963 for Λ, 0.998 for ASM and 0.994 for IDM. These results suggest that fractal and GLCM analysis are Urease exact methods with potentially high reproducibility. Statistical analysis was performed using anova test with Bonferroni confidence level adjustment and Spearman’s rank correlation coefficient in SPSS v 17.0 statistical package (SPSS, Chicago, IL, USA). Average values of DB, smoothed DB(biggest) and smoothed DB(small) are presented in Table 1. In newborn mice, average fractal dimension of MDC nuclear chromatin structure was 1.435 ± 0.017. In 10-day-old animals average DB was 1.406 ± 0.018 and in 20-day-old animals 1.398 ± 0.030. Mice aged 30 days had average DB of 1.380 ± 0.025. Using anova test for independent samples statistically highly significant difference was detected between the groups (F = 7.54, P < 0.001). When post-hoc analysis was applied, it was calculated that fractal dimension in animals aged 10 days, 20 days and 30 days was significantly lower (P < 0.05, P < 0.01 and P < 0.001 respectively, Fig. 2) when compared to the newborn mice (controls). There was no statistically significant difference (P > 0.05) in any other group pairs (10 days vs 20 days; 10 days vs 30 days; 20 days vs 30 days).
