RESUMO

Topological indices relate chemical structure to chemical reactivity, physical properties, and biological activity. Quantitative structure-activity relationships (QSPR) are mathematical models proposed for the correlation of various types of chemical reactivity, biological activity, and physical properties with topological indices/entropies. In this article, we have proposed the QSPR between the ve-degree of end vertices of edge based entropies and the physiochemical properties of benzene derivatives. We have designed a Maple-based algorithm for the computation of entropies. The relationship was analyzed using SPSS. We have shown that the physiochemical properties such as critical pressure, Henry's law, critical temperature, Gibb's energy, logP, critical volume, and molar refractivity can be predicted by entropies. All the results were highly positive and significant. The Randic, Balaban, and redefined third Zagreb entropies showed the best relations with physiochemical properties.Communicated by Ramaswamy H.

RESUMO

Nigella is one of the most studied plants because of its pharmacological properties like anti-parasitic, anti-inflammatory, neuro-protective, hepatoprotective, and anti-cancerous. In this study, about 20 species of the genus Nigella were reviewed and among them, N. damascene, N. glandulifera, and N. sativa are widely studied for their phytochemical and pharmacological effects. This review describes the phytochemical composition of the genus Nigella, which constitutes many of the compounds including alkaloids, flavonoids, saponins, and terpenoids. The extracts produced by using different solvents and the isolated compounds displayed a wide range of biological activity. These compounds were identified by different spectral techniques. The spectral detail of some advanced techniques including EIS-MS, UV/VIS, IR, 13 C-NMR, and 1 H-NMR of some important phytoconstituents of Nigella spp. has been compiled for the first time in this review which will be helpful to explore and further investigate the chemical composition of this genus.

RESUMO

INTRODUCTION: Focal segmental glomerulosclerosis (FSGS) is one of the common causes of end-stage kidney disease (ESKD) in adults with primary glomerular diseases. Information on clinical course and long-term renal outcome of primary FSGS in adults are scanty. We aimed to determine the clinical course and long-term outcome of primary FSGS in a large number of adult patients from a tertiary care kidney center in Pakistan. METHODS: A retrospective review of the clinical charts of all adults (≥ 16 years) with a biopsy proven diagnosis of FSGS presenting to Sindh Institute of Urology and Transplantation, Karachi, between January 1995 and December 2017 was carried out. Cases with secondary FSGS were excluded. Relevant data items were retrieved both at baseline and on last follow-up. RESULTS: Among 401 adults with primary FSGS, 144 (35.9%) were followed for a mean duration of 66.6 ± 27.4 months, out of which, 129 (89.5%) were treated with steroids and immunosuppressants. Response to steroids was obtained in 62 (48%) patients, while 67 (52%) showed no response. Among responders, 24/62 (38.7%) relapsed after a mean duration of 24.2 ± 23.2 weeks, who were re-treated with same dose of steroids alone or combined with cyclosporine and all achieved remission. The long-term outcomes were significantly different between steroid responsive and nonresponsive cohorts. None of the patients in steroid responsive group developed ESKD or died, while 7 (10.4%) patients in nonresponsive group developed ESKD and 2 (3%) died. CONCLUSION: Almost half of adults with primary FSGS achieved sustained remission with steroids and immunosuppressants and consequently exhibited excellent long-term outcome.  DOI: 10.52547/ijkd.6815.

RESUMO

Periodontal disease is a common complication, and conventional periodontal surgery can lead to severe bleeding. Different membranes have been used for periodontal treatment with limitations, such as improper biodegradation, poor mechanical property, and no effective hemostatic property. Guided tissue regeneration (GTR) membranes favoring periodontal regeneration were prepared to overcome these shortcomings. The mucilage of the chia seed was extracted and utilized to prepare the guided tissue regeneration (GTR) membrane. Lignin having antibacterial properties was used to synthesize lignin-mediated ZnO nanoparticles (∼Lignin@ZnO) followed by characterization with analytical techniques like Fourier-transform infrared spectroscopy (FTIR), UV-visible spectroscopy, and scanning electron microscope (SEM). To fabricate the GTR membrane, extracted mucilage, Lignin@ZnO, and polyvinyl alcohol (PVA) were mixed in different ratios to obtain a thin film. The fabricated GTR membrane was evaluated using a dynamic fatigue analyzer for mechanical properties. Appropriate degradation rates were approved by degradability analysis in water for different intervals of time. The fabricated GTR membrane showed excellent antibacterial properties against Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) bacterial species.

RESUMO

OBJECTIVES: As part of the PIONEER Consortium objectives, we have explored which diagnostic and prognostic factors (DPFs) are available in relation to our previously defined clinician and patient-reported outcomes for prostate cancer (PCa). DESIGN: We performed a systematic review to identify validated and non-validated studies. DATA SOURCES: MEDLINE, Embase and the Cochrane Library were searched on 21 January 2020. ELIGIBILITY CRITERIA: Only quantitative studies were included. Single studies with fewer than 50 participants, published before 2014 and looking at outcomes which are not prioritised in the PIONEER core outcome set were excluded. DATA EXTRACTION AND SYNTHESIS: After initial screening, we extracted data following the Checklist for Critical Appraisal and Data Extraction for Systematic Reviews of prognostic factor studies (CHARMS-PF) criteria and discussed the identified factors with a multidisciplinary expert group. The quality of the included papers was scored for applicability and risk of bias using validated tools such as PROBAST, Quality in Prognostic Studies and Quality Assessment of Diagnostic Accuracy Studies 2. RESULTS: The search identified 6604 studies, from which 489 DPFs were included. Sixty-four of those were internally or externally validated. However, only three studies on diagnostic and seven studies on prognostic factors had a low risk of bias and a low risk concerning applicability. CONCLUSION: Most of the DPFs identified require additional evaluation and validation in properly designed studies before they can be recommended for use in clinical practice. The PIONEER online search tool for DPFs for PCa will enable researchers to understand the quality of the current research and help them design future studies. ETHICS AND DISSEMINATION: There are no ethical implications.

RESUMO

ABSTRACT OBJECTIVE To determine the seroprevalence of hepatitis B and C among immigrants residing refugee camps in Muzaffarabad, Azad Kashmir, Pakistan, and to identify possible risk factors for hepatitis B virus (HBV) and hepatitis C virus (HCV) transmission. METHODS Around 1,225 individuals inhabiting Muzaffarabad refugee camps, participated in the study. A qualitative Immuno-Chromatographic Technique was used for initial screening and PCR test was used for detection of HBV and HCV in participants. The major risk factors for HBV and HCV transmission were assessed using a questionnaire approach. RESULTS Around 86 (7.0%) individuals were observed for hepatitis B surface antigen (HBsAg) presence, and 215 (17.5%) individuals were found positive for Anti-HCV. Only 32 (2.6%) individuals were confirmed for HBV DNA and 126 (10.3%) individuals were positive for HCV RNA after PCR. Demographically, both HBsAg and Anti-HCV were found more prevalent in female (4.4% HBsAg and 10.8% Anti-HCV) population as compared to male (2.6% HBsAg and 6.7% Anti-HCV) population. Surprisingly, the HBsAg (23.5%) and Anti-HCV (41.1%) appeared to be more frequent in the age group 62-75 years. Previous history of hepatitis in the family (p < 0.0001), blood transfusion (p = 0.0197) dental treatment (p < 0.0001) and tattooing or piercing on any part of the body (p = 0.0028) were assessed as significant risk factors in HBV and HCV transmission. CONCLUSIONS Presence of 7.0% HBsAg and 17.5% Anti-HCV in a small fragment of the migrant population cannot be overlooked. Lack of awareness among people and negligence of health department could escalate the situation.

RESUMO

BACKGROUND: The role of percutaneous coronary intervention (PCI) vs coronary artery bypass grafting (CABG) in patients with coronary artery disease (CAD) and concomitant end-stage renal disease (ESRD) remains unknown. RESEARCH DESIGN & METHODS: The National Inpatient Sample (NIS) (2002-2017) was queried to identify all cases of CAD and ESRD. The relative merits of PCI vs CABG were determined using a propensity-matched multivariate logistic regression model. Adjusted odds ratios (aOR) for mortality and other in-hospital complications were calculated. RESULTS: A total of 350,623 [CABG = 112,099 (32%) and PCI = 238,524 (68%)] hospitalizations were included in the analysis. The overall adjusted odds for major bleeding (aOR 1.28, 95% CI 1.25-1.31, P < 0.0001), post-procedure bleeding (aOR 5.19, 95% CI 4.93-5.47, P < 0.0001), sepsis (aOR 1.29, 95% CI 1.26-1.33, P < 0.0001), cardiogenic shock (aOR 1.23, 95% CI 1.20-1.26, P < 0.0001), and in-hospital mortality (aOR 1.65, 95% CI 1.61-1.69, P < 0.0001) were significantly higher for patients undergoing CABG compared with PCI. The need for intra-aortic balloon pump (IABP) placement (aOR 2.52, 95% CI 2.45-2.59, P < 0.001) was higher in the CABG group, while the adjusted odds of vascular complications were similar between the two groups (aOR 0.99, 95% CI 0.94-1.06, P = 0.82). As expected, patients undergoing CABG had a higher mean length of stay and mean cost of hospitalization. CONCLUSION: CABG in ESRD may be associated with higher in-hospital complications, increased length of stay, and higher resource utilization.

RESUMO

Malachite green (MG) is extensively applied in aquaculture worldwide as a therapeutic agent. MG and its primary metabolite leucomalachite green (LMG) are commonly detected in aquaculture products. MG can cause serious health concerns (in vivo carcinogenic/genotoxic). The extensive water solubility of MG leads to water pollution and hence it is mandatory to remove MG from water. The current study explores adsorptive removal of MG from water using highly water stable Zeolitic Imidazolate framework/graphene oxide composites (ZIF-67@GO). Adsorption performance of newly synthesized composites is justified for MG removal with excellent results of pseudo second order (R2 = 0.99955) which is well-fitted in this case. ZIF-67@GO data of adsorption isotherm for MG is observed using Freundlich Model (R2 = 0.99999) and with adsorption capacity value observed (134.79 mg/g) with removal efficiency of 99.18%, indicates π-staking and electrostatic association between ZIF-67@GO and MG molecules. Synthesized material has retained reusability while removal efficiency reduced only by 6% after many cycles. Furthermore, factors effecting absorption like contact time, pH, adsorbent dose and quantity and temperature are also determined.

RESUMO

BACKGROUND: There is a paucity of literature regarding the association of high oncotic priming solutions for pediatric cardiopulmonary bypass (CPB) and outcomes, and no consensus exists regarding the composition of optimal CPB priming solution. This study aimed to examine the impact of high oncotic pressure priming by the addition of 20% human albumin on outcomes. METHODS: Double-blinded, randomized controlled study was done in the pediatric cardiac intensive care unit of a tertiary care hospital. Consecutive children with congenital heart diseases admitted for open-heart surgery were randomized into two groups, where the study group received an additional 20% albumin to conventional blood prime before CPB initiation. RESULTS: We enrolled 39 children in the high oncotic prime (added albumin) group and 37 children in the conventional prime group. In the first 24-hour postoperative period, children in the albumin group had significantly lower occurrence of hypotension (28.2% vs 54%, P = .02), requirement of fluid boluses (25.6% vs 54%, P = .006), and lactate clearance time (6 vs 9 hours, P < .001). Albumin group also had significantly higher platelet count (×103/µL) at 24 hours (112 vs 91, P = .02). There was no significant difference in intra-CPB hemodynamic parameters and incidence of acute kidney injury. In subgroup analysis based on risk category, significantly decreased intensive care unit stay (4 vs 5 days, P = .04) and hospital stay (5 vs 7 days, P = .002) were found in the albumin group in low-risk category. CONCLUSION: High oncotic pressure CPB prime using albumin addition might be beneficial over conventional blood prime, and our study does provide a rationale for further studies.

RESUMO

Small cell carcinoma (SCC) is an aggressive malignancy most commonly described in the lung. We present a case of a 61-year-old male who presented with a neck swelling and was subsequently found to have metastatic SCC of the prostate. Clinicians should be aware that it metastasizes early. Unlike conventional prostate adenocarcinoma, it is not a prostate-specific antigen (PSA) secreting tumor hence serum levels do not correlate with disease severity, and a low PSA reading may give false reassurance. In the future, further studies on genomic typing and novel targeted therapies may achieve better clinical outcomes for patients with this aggressive type of prostate cancer.

RESUMO

Seed extracts of Nymphia alba Linn. and Lupinus polyphyllus Lindl. were analyzed for fatty acid composition, functional group analysis and antioxidant activity. The petroleum ether extract of seeds were found dominant in unsaturated fatty acids with oleic acid (39.9%) and linoleic acid (29.6%) in L. polyphyllus and linoleic (37.5%) and oleic acid (10.9%) in N. alba. All the defatted seed extracts of N. alba and L. polyphyllus found to have powerful DPPH, ABTS, H2O2 and NBT antioxidant radical scavenging activity with reference to butylated hydroxy toluene (BHT). The defatted seed extracts were further analyzed with functional group analysis through FTIR found to contain numerous functional groups which may be responsible for their antioxidant activity.

RESUMO

Objective To compare the effect of incentive spirometry with Acapella (Smiths Medical Inc, Carlsbad, California) in physiotherapy after coronary artery bypass surgery. Methods A randomized controlled trial comparing incentive spirometry with Acapella was conducted in the intensive care unit of Chaudhary Pervaiz Elahi Institute of Cardiology (CPEIC) Multan. The study began from December 2017 to August 2019 after getting approval from the ethical committee of the hospital. Informed written consent was taken from all 270 patients who were included in the study. Patients who underwent coronary artery bypass graft (CABG) were divided into two groups by the lottery method. The primary end-point of the study was to check the blood gases on Day 3 after the procedure at room air and compare it with the baseline and with blood gases immediately after the procedure. SPSS 23 (IBM Corp., Armonk, NY) was used to analyze the data of this study. For qualitative variables in data such as gender, place of living, patients with any comorbidities, and education status were statistically analyzed in percentage and frequencies. For numerical variables, such as age, body mass index, blood gases values, distance covered in a six-minute walk test, and spirometry values were analyzed and statistically measured as mean and standard deviation. A P-value of less than .05 was considered significant. Results The mean partial pressure of oxygen (PaO2) of incentive spirometry was 58.1±2.31 and 67.2±3.24 after extubation and after three days, respectively. While the PaO2 of Acapella was 56.3±3.43 and 66.4±3.54 after extubation and after three days, respectively. The mean PCO2 of incentive spirometry was 41.4±3.26 and 36.1±2.11 after extubation and after three days, respectively. While the partial pressure of carbon dioxide (PCO2) of Acapella was 39.4±2.55 and 37.5±3.58 after extubation and after three days, respectively. The differences were statistically significant at p-value ≤0.05. Conclusion It was concluded that both Acapella and incentive spirometry treatment after coronary artery bypass graft improved blood gases.

RESUMO

INTRODUCTION: Ureteric stents are frequently placed following endo-urological procedures. These stents cause significant morbidity for patients. Standard ureteric stents are removed by flexible cystoscopy. This procedure can be unpleasant for patients and requires additional resources. A newly designed magnetic stent allows removal in an outpatient setting. The aim of our study is to compare the magnetic stent and standard ureteric stents with regard to morbidity, pain on stent removal and cost-effectiveness. METHODS: This study was carried out across two sites between September 2016 and July 2017. In site A, a magnetic stent (Urotech, Black-Star®) is removed by magnetic retrieval device. Fifty consecutive patients completed the validated Ureteric Stent Symptom Questionnaire (USSQ) and visual analogue scale (VAS) at the time of stent removal. On site B, a soft polyurethane stent (Cook Universa) was removed by flexible cystoscopy. Fifty patients were identified retrospectively and completed questionnaires by post. Cost analysis was also performed. RESULTS: One hundred questionnaires were included for analysis. No significant difference in stent morbidity as assessed by the USSQ was shown between both groups. Median duration of stenting was significantly shorter in the magnetic stent group (5.5 versus 21.5 days, p < 0.001). Mean pain on stent removal was significantly less with magnetic retrieval (2.9 versus 3.9, p < 0.05). Complication rates were similar in both groups. Cost analysis showed a cost saving of €203 per patient with the magnetic stent group. CONCLUSION: Magnetic stents cause similar morbidity for patients compared with standard stents removed by flexible cystoscopy; they are associated with less pain at removal and are cost saving.

RESUMO

PURPOSE: Human microbiota comprises of a variety of organisms ranging from bacterial species to viruses, fungi, and protozoa which are present on the epidermal and mucosal barriers of the body. It plays a key role in health and survival of the host by regulation of the systemic functions. Its apparent functions in modulation of the host immune system, inducing carcinogenesis and regulation of the response to the cancer therapy through a variety of mechanisms such as bacterial dysbiosis, production of genotoxins, pathobionts, and disruption of the host metabolism are increasingly becoming evident. METHODS: Different electronic databases such as PubMed, Google Scholar, and Web of Science were searched for relevant literature which has been reviewed in this article. RESULTS: Characterization of the microbiome particularly gut microbiota, understanding of the host-microbiota interactions, and its potential for therapeutic exploitation are necessary for the development of novel anticancer therapeutic strategies with better efficacy and lowered off-target side effects. CONCLUSION: In this review, the role of microbiota is explained in carcinogenesis, mechanisms of microbiota-mediated carcinogenesis, and role of gut microbiota in modulation of cancer therapy.

RESUMO

Background: Bronchogenic cysts are congenital malformations from abnormal budding of embryonic foregut and tracheobronchial tree. We present a case of bronchogenic cyst with severe back pain, epigastric distress and refractory nausea and vomiting.   Case Presentation: A 44-year-old Hispanic female presented with a 3-week history of recurrent sharp interscapular pain radiating to epigastrium with refractory nausea and vomiting. She underwent cholecystectomy 2-years ago. Computed tomography (CT) abdomen at that time showed a subcarinal mass measuring 5.4 X 5.0 cm. Subsequent endoscopic ultrasound diagnosed it as a bronchogenic cyst. Endobronchial ultrasound (EBUS) guided aspiration resulted in incomplete drainage and she was discharged after partial improvement. Current physical examination showed tachycardia and tachypnea with labs showing leukocytosis, elevated inflammatory markers, and hypokalemic metabolic alkalosis. CT chest showed an increased size of the bronchogenic cyst (9.64 X 7.7 cm) suggestive of possible partial cyst rupture or infected cyst. X-ray esophagram ruled out esophageal compression or contrast extravasation. Patient's symptoms were refractory to conservative management. The patient ultimately underwent right thoracotomy with cyst excision that resulted in complete resolution of symptoms. Conclusion: Bronchogenic cysts are the most common primary cysts of mediastinum with the prevalence of 6%. The most common symptoms are chest pain, dyspnea, cough, and stridor. Diagnosis is made by chest X-Ray and CT chest. Magnetic resonance imaging chest and EBUS are more sensitive and specific. Symptomatic cysts should be resected unless surgical risks are high. Asymptomatic cysts in younger patients should be removed due to low surgical risk and potential late complications. Watchful waiting has been recommended for asymptomatic adults or high-risk patients. This case presents mediastinal bronchogenic cyst as a cause of back, nausea and refractory vomiting. Immediate surgical excision in such cases should be attempted, which will lead to resolution of symptoms and avoidance of complications.

RESUMO

A pot experiment was conducted to evaluate the potential of two plant growth promoting rhizobacteria (PGPR) viz. Bacillus sp. CIK-516 and Stenotrophomonas sp. CIK-517Y for improving the growth and Ni uptake of radish (Raphanus sativus) in the presence of four different levels of Ni contamination (0, 50, 100, 150 mg Ni kg-1 soil). Plant growth, dry biomass, chlorophyll and nitrogen contents were significantly reduced by the exogenous application of Ni, however, bacterial inoculation diluted the negative impacts of Ni stress on radish by improving these parameters. PGPR strain CIK-516 increased root length (9-27%), shoot length (8-27%), root dry biomass (2-32%), shoot dry biomass (9-51%), root girth (6-48%), total chlorophyll (4-38%) and shoot nitrogen contents (11-15%) in Ni contaminated and non-contaminated soils. Positive regulation of chlorophyll and nitrogen contents by the inoculated plants shows plant tolerance mechanism of Ni stress. Bacterial strain (CIK-516) exhibited indole acetic acid and 1-amino-cyclopropane-1-carboxylate deaminase potentials which would have helped radish plant to stabilize in Ni contaminated soil and thereby increased Ni uptake (24-257 in shoot and 58-609 in root mg kg-1 dry biomass) and facilitated accumulation in radish (bioaccumulation factor = 0.6-1.7) depending upon soil Ni contamination. Based on the findings of this study, it might be suggested that inoculation with bacterial strain CIK-516 could be an efficient tool for enhanced Ni phytoextraction in radish.

RESUMO

Fatty acid functionalized chitosan conjugates are of great interest in cancer therapeutics because of its internalization through receptor mediated endocytosis into the cancer cells. Keeping the above fact into consideration, herein we synthesized the undec-10-enoic acid functionalized chitosan based undecyl-chitosan (U-CS) nano-bioconjugate with the use of DCC as a coupling agent. The U-CS conjugate synthesized was confirmed and characterized by FTIR, 1H NMR, TGA, XRD, SEM and TEM analysis. Generally, it is well established that conjugates of oleic acid with human Alpha-lactalbumin (HAMLET) induce cytotoxicity in the altered cells, but not in healthy cells. To check our presumptions, anti-bacterial and anti-cancer potential of U-CS was evaluated against bacterial pathogens (Gram +ve and Gram -ve) and human cancer cell lines (HeLa, MDA-MB-231 and Hep3B). The results of our study clearly revealed that conjugate showed enhance anti-bacterial, anti-biofilm as well as anti-cancer efficacy as compared to pure and free form of the chitosan.

RESUMO

BACKGROUND: Medicines are a main therapeutic intervention provided within hospitals and their proper use in the outpatient setting is important for patients and the community. The objective of this study was to evaluate drug use patterns in the outpatient departments (OPDs) of two tertiary care hospitals (Bahawal Victoria Hospital and Civil Hospital) in the Bahawalpur district of the Punjab province of Pakistan by employing the standard World Health Organization/International Network of Rational Use of Drugs (WHO/INRUD) drug use indicators. METHODS: A descriptive, cross-sectional study design was employed. For assessing the prescribing indicators a sample of 2400 prescriptions were systematically reviewed out of a total of 1,560,000 prescriptions written from 1st April 2014 to 31st March 2015. A total of 600 randomly selected patients and all pharmacy personnel were observed and interviewed to investigate the patient-care and facility-specific indicators. We used the published ideal standards for each of the WHO/INRUD indicators for comparison purposes. RESULTS: Among the prescribing indicators, the average number of drugs per prescription was 2.8 (SD = 1.3), the drugs prescribed by generic name were 56.6 %, the encounters with an antibiotic prescribed were 51.5 %, no injections were prescribed and 98.8 % of the drugs prescribed were from the Essential Drugs List (EDL). Among the patient-care indicators, the average consultation time was 1.2 min (SD = 0.8), the average dispensing time was 8.7 s (SD = 4.9), the percentage of drugs actually dispensed was 97.3 %, the percentage of drugs adequately labeled was 100 % and the patients' knowledge of correct dosage schedule was 61.6 %. Among the facility-specific indicators, all OPDs had a copy of the EDL and 72.4 % of the key drugs were available in stock. CONCLUSION: Irrational use of drugs was observed in both OPDs. Polypharmacy, brand prescribing, over-prescribing of antibiotics, short consultation and dispensing times, lack of patients' knowledge about prescribed medicines and unavailability of all key drugs in stock were the major issues that need attention of the healthcare authorities. This study necessitates the requirement to implement the relevant WHO recommended core interventions to promote rational use of medicines in these hospital-based OPDs.

RESUMO

Lactobacillus rhamnosus GG (LGG), a gram-positive lactic acid bacterium, is one of the most widely used probiotics; while fewer gram-negative probiotics including Escherichia coli Nissle 1917 (EcN) are characterized. A mechanistic understanding of their individual and interactive effects on human rotavirus (HRV) and immunity is lacking. In this study, noncolonized, EcN-, LGG-, and EcN + LGG-colonized neonatal gnotobiotic (Gn) pigs were challenged with HRV. EcN colonization is associated with a greater protection against HRV, and induces the highest frequencies of plasmacytoid dendritic cells (pDCs), significantly increased NK-cell function and decreased frequencies of apoptotic and TLR4+ mononuclear cells (MNCs). Consistent with the highest NK-cell activity, splenic CD172+ MNCs (DC enriched fraction) of EcN-colonized pigs produced the highest levels of IL-12 in vitro. LGG colonization has little effect on the above parameters, which are intermediate in EcN + LGG-colonized pigs, suggesting that probiotics modulate each other's effects. Additionally, in vitro EcN-treated splenic or intestinal MNCs produce higher levels of innate, immunoregulatory and immunostimulatory cytokines, IFN-α, IL-12, and IL-10, compared to MNCs of pigs treated with LGG. These results indicate that the EcN-mediated greater protection against HRV is associated with potent stimulation of the innate immune system and activation of the DC-IL-12-NK immune axis.
