Abstract
Thiram, a typical fungicide pesticide, is widely used in agricultural production. The presence of thiram residues is not only due to over-utilization, but is also primarily attributed to long-term accumulation. However, there is a paucity of information regarding the impact of prolonged utilization of thiram at low doses on the gut microbiota, particularly with respect to gut fungi. Our objective is to explore the effect of thiram on broilers from the perspective of gut microbiota, which includes both bacteria and fungi. We developed a long-term low-dose thiram model to simulate thiram residue and employed 16 S rRNA and ITS gene sequencing to investigate the diversity and profile of gut microbiota between group CC (normal diet) and TC (normal diet supplemented with 5 mg/kg thiram). The results revealed that low doses of thiram had a detrimental effect on broiler's growth performance, resulting in an approximate reduction of 669.33 g in their final body weight at day 45. Our findings indicated that low-dose thiram had a negative impact on the gut bacterial composition, leading to a notable reduction in the abundance of Merdibacter, Paenibacillus, Macrococcus, Fournierella, and Anaeroplasma (p < 0.05) compared to the CC group. Conversely, the relative level of Myroides was significantly increased (p < 0.05) in response to thiram exposure. In gut fungi, thiram significantly enhanced the diversity and richness of gut fungal populations (p < 0.05), as evidenced by the notable increase in alpha indices, i.e. ACE (CC: 346.49 ± 117.27 vs TC: 787.27 ± 379.14, p < 0.05), Chao 1 (CC: 317.63 ± 69.13 vs TC: 504.85 ± 104.50, p < 0.05), Shannon (CC: 1.28 ± 1.19 vs TC: 5.39 ± 2.66, p < 0.05), Simpson (CC: 0.21 ± 0.21 vs TC: 0.78 ± 0.34, p < 0.05). Furthermore, the abundance of Ascomycota, Kickxellomycota, and Glomeromycota were significantly increased (p < 0.05) by exposure to thiram, conversely, the level of Basidiomycota was decreased (p < 0.05) in the TC group compared to the CC group. Overall, this study demonstrated that low doses of thiram induced significant changes in the composition and abundance of gut microbiota in broilers, with more pronounced changes observed in the gut fungal community as compared to the gut bacterial community. Importantly, our findings further emphasize the potential risks associated with low dose thiram exposure and have revealed a novel discovery indicating that significant alterations in gut fungi may serve as the crucial factor contributing to the detrimental effects exerted by thiram residues.

Abstract
Aflatoxin B1 (AFB1) is the primary mycotoxin that is responsible for the severe issues plaguing poultry farming. The study was aimed to explore the relevant pathways connected with immunity (inflammation, oxidative stress and apoptosis) in an AFB1-challenged chicken by using Penthorum chinense Prush extract (PCPE) in Bursa of Fabricius (BF) of broilers. A total one hundred and eighty day-old broilers were divided into six groups: Control, AFB1 (3 mg/kg feed), Yin-Chen-Hao Tang extract (YCHT) (10 ml/kg feed), and PCPE groups (low 1 g/kg, medium 2 g/kg, and high 3 g/kg PCPE/kg feed) respectively. The results showed that AFB1-challenged birds showed significant decrease in growth, BF weight index, serum antioxidant biomarkers and histopathological changes in BF tissues. The mRNA analysis showed that AFB1 upregulated the apoptosis associated genes (caspase-3, caspase-9, Bak, Bax and p53) and downregulated BCL-2. Additionally, AFB1 downregulated expression level of Nuclear Factor EF-2 (Nrf2) related genes (Nrf2, HO-1, NQO1 and GCLC) in the BF of broilers. The PCPE treatment showed positive impact on final weight gain, bursal index, and reversing of pathological changes in the BF of AFB1-challanged broilers. PCPE ameliorated oxidative stress generated by AFB1, as an increase in antioxidant enzyme activities, alleviated histopathological changes in BF, enhanced the Nrf2 expression levels and lowered the apoptosis gene expressions as compared to AFB1. The findings revealed that PCPE activated the Nrf2 pathway, antioxidant defense system and modulated the apoptosis in the BF of broiler chicken.

Abstract
Aflatoxin B1(AFB1) is the main secondary metabolite produced by Aspergillus flavus, which is highly toxic, carcinogenic, mutagenic and teratogenic. It can induce immune imbalance in animals or humans. Penthorum chinense Pursh (PCP) is a traditional herbal plant that has been used as a hepatoprotective drug with a long history in China. Based on the theory of traditional Chinese Medicine, we prepared Penthorum chinense Pursh Compound (PCPC) by combining four herbal medicines: 5 g Penthorum chinense Pursh, 5 g Radix bupleuri, 1 g Artemisia capillaris Thunb and 1 g Radix glycyrrhizae. The role of the Penthorum chinense Pursh Compound (PCPC) in preventing AFB1-induced immune imbalance in broiler chickens was studied. A total of 180 broiler chickens were equally distributed in six groups: controls, AFB1, YCHD and high-, medium- and low-dose PCPC treatment groups. After 28 days, broilers were anesthetized, and serum spleen and thymus samples were collected for analysis. Results show that AFB1 significantly increased and decreased the relative organ weight of the spleen and thymus, respectively. Pathological section of hematoxylin/eosin (H&E) stained spleen sections showed that AFB1 resulted in splenic tissue damage. Both the serum levels of Immunoglobulin A (IgA) and Immunoglobulin G (IgG) were suppressed in the AFB1 group. IL-6 was elevated in the AFB1 group. The balance between pro-inflammatory cytokines (IFN-γ and IL-2) and anti-inflammatory cytokine (IL-4) was disturbed by AFB1. The apoptosis-related protein and JAK/STAT pathway-related gene expression indicated that AFB1-induced apoptosis via JAK/STAT pathway. PCPC has proven its immunoprotective effects by preventing AFB1-induced immune imbalance. PCPC can be applied as a novel immune-modulating medicine in broiler chickens. It can be applied as a novel immune modulator in veterinary clinical practice.

Abstract
Aflatoxin B1 (AFB1) is a commonly occurring toxicant in animal and human diets, leading to hazardous effects on health. AFB1 is known to be a hepato-toxicant, and the intestinal barrier may play a crucial role in reversing AFB1-induced liver injury. This study aimed to optimize the extraction conditions of Penthorum chinense Pursh Compound Flavonoids (PCPCF) by the response surface method with a Box-Behnken design and investigate the effects of PCPCF on AFB1-induced liver injury in broilers. A total of 164 one-day-old broilers were divided into seven groups, including Control, PCPCF (400 mg PCPCF/kg feed), AFB1 (3 mg AFB1/kg feed), and YCHT (Yin-Chen-Hao-Tang extract, 3 mg AFB1 +10 mL YCHT/kg feed) and low, medium, and high dose groups (PCPCF at 3 mg AFB1 +200, 400, 600 mg respectively). Samples of serum, liver, duodenum, and cecum contents were collected at 14th and 28th days for further analysis. The results showed that the maximum extraction rate of PCPCF was 8.15 %. PCPCF was rich in rutin, quercetin, liquiritin and kaempferol, and significantly inhibited the growth of Aspergillus flavus. The addition of PCPCF improved the growth performance of AFB1-injury broilers, modulated liver function, and increased serum immunoglobulin levels. PCPCF also alleviated liver pathological and oxidative stress damages caused by AFB1 and decreased AFB1-DNA and AFB1-lysine content in the liver. Furthermore, PCPCF supplementation ameliorated intestinal pathological damage, improved intestinal permeability of duodenum in the AFB1-induced broilers, and repaired the intestinal mucosal and mechanical barrier associated with the Notch signaling pathway. Meanwhile, PCPCF improved the intestinal flora structure of AFB1-damaged broilers and increased the abundance of beneficial bacteria. In conclusion, PCPCF ameliorated the adverse effects of AFB1 on growth performance and alleviated liver damage by repairing the intestinal barrier and improving intestinal health of broiler chicken.

Abstract
Pathological conditions and harmful drugs cause many gastrointestinal diseases in broiler chicken. The current study was conducted to investigate the effect of trace elements zinc (Zn) and selenium (Se) supplementation on histomorphology, immunological role, and functional activity of goblet cells (GCs) of the small intestine. The Alcian blue-periodic acid-Schiff (AB-PAS) was performed to assess the histomorphological changes in GCs, which revealed the regular dispersion with high electron density of GCs throughout the mucosal surface in the supplemented group. However, irregular dispersion with low electron density of GCs was present in the control group. The immunological functional role of GCs within the small intestine was examined by mucicarmine staining, immunohistochemistry, and immunofluorescence. The results showed a high mucin glycol protein secretion in the supplemented group, whereas limited mucin glycol protein secretion in the control group. Furthermore, the biological significance showed a high and low immunoreactivity of Muc2 and Muc13 in the supplemented and control groups, respectively. Immunofluorescence was used to confirm the immunosignaling of Muc2. Results revealed high immunosignaling of Muc2 at the apical part of the small intestine in the supplementation group, while low immunosignaling of Muc2 in the control group. Results suggest that trace element supplementation had significant effect on morphology and immunological role of GCs, which might be essential for immune function and health status of broiler chicken.

Abstract
Abstract
Introduction
Positron emission tomography (PET) myocardial perfusion imaging (MPI) is an established test in the diagnosis and prognosis of patients with cardiac diseases. Silicon photomultiplier (SiPM) digital PET is the latest advancement in this technology with improved detector sensitivity, coincidence time resolution, and spatial resolution, allowing for Sub-milliSievert cardiac PET MPI.
Purpose
We aimed to assess the independent and incremental prognostic value of SiPM digital PET derived coronary flow reserve (CFR) to clinical and nuclear variables.
Methods
Consecutive patients who had clinically indicated digital Rubidium PET MPI were included. Rubidium dose was 10–20 mCi according to patient's weight. Patients were followed from the date of imaging to incident major adverse cardiovascular event (MACE: inclusive of all-cause death, myocardial infarction, admission for heart failure and late revascularization – percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) >90 days after imaging).
Results
The study population consisted of 2,893 patients with clinically indicated PET MPI (mean age 67 (±12), 53% male, 41% Caucasian). Cardiovascular risk factors were prevalent (88% hypertensive, 80% dyslipidemic, 47% diabetics, 18% ever smoking). After a mean follow-up of 8±7 months, 250 patients (8.6%, 10.7 per 1000 person-year) experienced MACE (90 D / 38 MI / 51 PCI / 11 CABG / 113 HF). In nested multivariable cox models, CFR was independently associated with incident MACE (HR 0.38, 95% CI 0.29–0.51, p<0.001) and incrementally improved risk prediction (Harrell's C=0.77, p=0.002).
Conclusion
Our findings showed that a Sub-milliSievert SiPM digital PET-derived CFR provided incremental value in risk-stratifying patients and identifying those at increased risk of incident outcomes.

Abstract
Abstract
Introduction
Positron emission tomography (PET) myocardial perfusion imaging (MPI) derived coronary flow reserve (CFR) is an important risk-stratifying tool to tailor management of patients with coronary artery disease. Resting myocardial blood flow (MBF) is positively correlated to the product of resting heart rate and systolic blood product (resting pressure product – RPP), and can in turn lead to lower CFR in the setting of normal stress MBF.
Purpose
We aimed to assess the comparative incremental prognostic value of uncorrected to RPP-corrected CFR in predicting incident events.
Methods
Consecutive patients who had clinically indicated PET MPI were included. Patients were followed from the date of imaging to incident major adverse cardiovascular event (MACE: inclusive of all-cause death, myocardial infarction, admission for heart failure and late revascularization – percutaneous coronary intervention (PCI) or coronary artery bypass graft (CABG) >90 days after imaging).
Results
The study population consisted of 2,893 patients with clinically indicated PET MPI (mean age 67 (±12), 53% male, 41% Caucasian). Cardiovascular risk factors were prevalent (88% hypertensive, 80% dyslipidemic, 47% diabetics, 18% ever smoking). After a mean follow-up of 8±7 months, 250 patients (8.6%, 10.7 per 1000 person-year) experienced MACE (90 D/38 MI/51 PCI/11 CABG/113 HF). Both uncorrected and corrected CFR were independently associated with incident MACE (HR 0.38, 95% CI 0.29–0.51, p<0.001 and 0.61, 95% CI 0.50–0.76, p<0.001 respectively). A comparison of model incremental prognostic value showed the model with uncorrected CFR had a statistically higher Harrell's C (0.76 vs 0.77, p=0.23).
Conclusion
Our findings showed that the prognostic value of CFR was preserved even in the setting of high resting blood pressure or heart rate. This suggests that correction for RPP should be selective.

Abstract
Abstract
Introduction
Although most patients recovering from acute COVID-19 infection have complete resolution of symptoms, some have cardiopulmonary symptoms lingering long after the acute phase of the disease. One proposed mechanism involves chronicity of COVID-19 associated with myocarditis and endotheliopathy.
Purpose
To determine the coronary microvascular health of patients with prior COVID-19 and no known coronary artery disease (CAD) using positron emission tomography (PET).
Methods
Cases consisting of patients without known CAD but previous COVID-19 infection who had clinically indicated PET imaging were matched 1:4 on clinical and cardiovascular risk factors to controls having no prior COVID-19 infection. Myocardial blood flow (MBF) in ml/gm/min was obtained from dynamic images at rest and peak hyperemia. The coronary flow reserve (CFR) was calculated as the ratio of stress to rest MBF of the left ventricle. Coronary microvascular dysfunction (CMD) was defined as CFR<2.
Results
The study population consisted of 315 patients, 25% (n=80) of which had prior COVID-19 infection (mean±SD age 64±11 years, 46% men). The median (IQR) number of days between COVID-19 infection and PET imaging was 190 (85–268) days. After adjusting for age, gender and cardiovascular risk factors, patients with prior COVID-19 and no known CAD had a statistically significant higher odds of having a CFR <2 (OR 4.9, 95% CI 2.3–10.1 p<0.001) and CFR <2 normalized to patient's rate-systolic blood pressure product (OR 2.8, 95% CI 1.6–5.0 p=0.001). The annualized event rate for the composite outcome of all-cause death, myocardial infarction, admission for heart failure exacerbation and late revascularization was higher in cases vs controls and in those with CMD.
Conclusion
Our analysis showed that patients with prior COVID-19 and no known CAD had higher rates of CMD, and that the presence of CMD was associated with higher risk of incident cardiovascular events.

Abstract
Abstract
Introduction
Coronary artery calcium score (CACS) and exercise capacity (EC) are both independent prognostic tests in coronary artery disease (CAD).
Purpose
We aimed to assess the incremental prognostic role of EC to CACS, particularly in those with absent or low coronary calcification.
Methods
The cohort consisted of patients who had clinically indicated exercise stress testing and CACS assessment with a median of 27 days of each other. EC was defined based on peak metabolic equivalents (METS) achieved during exercise stress test. CACS was determined using the Agatston method. Patients were followed from the latest test date to incident MACE (inclusive of all-cause death, non-fatal myocardial infarction, late revascularization and admission for heart failure).
Results
There were a total of 1932 patients in the study population (mean age 56±12, 42% female, 48% hypertension, 21% diabetes, 48% dyslipidemia). Peak METS <6 was achieved in 8% of patients, and the median (IQR) CACS was 9 (0–203). Patients with EC <6 METS had doubling of their event rate across strata of CACS, even amongst patients with absent or low coronary calcifications (CACS 0: 4.6 vs 10.9; CACS 1–99: 10.4 vs 20.4; MACE per 1000 person year in patients with peak METS ≥ vs <6 respectively) (Figure 1).
Conclusion
Our findings showed that poor exercise capacity was associated with higher risk even in patients with absent or low coronary calcification.

Abstract
Acute liver injury (ALI), manifested by acute hepatocellular damages and necrosis, is a life-threatening clinical syndrome and Penthorum Chinense Pursh (PCP) is a well-known folk medicine practiced for liver-related diseases. This study aimed to investigate the ameliorative effects of PCP extract (PCPE) on carbon tetrachloride (CCl4) induced ALI in dogs via mitogen-activated protein kinase (MAPK) and Nuclear factor κB (NF-κB) signaling pathway. Healthy dogs were induced by CCl4 and treated with different dosage regimes of PCPE for 7 days. CCl4 produced acute liver injury and induced both oxidative stress and an inflammatory response in dogs. The PCPE significantly ameliorated and improved vacuolar inflammatory lesions in liver tissues during ALI, enhanced activity of superoxide dismutase, and restored glutathione peroxidase, further significantly reducing the indices of malondialdehyde and nitric oxide in serum. Inflammatory factors (IL-1β, IL-6, and TNF-α) were declined and anti-inflammatory factors (IL-10) were increased by the application of PCPE. PCPE treatment, down-regulated the MEKK4, MKK3, p38MAPK, MSK1, and NF-κB, and upregulated the IkB mRNA levels (p < 0.01) in ALI affected dogs. In conclusion, PCPE repaired acute liver injury by improving antioxidant enzymes and by reducing oxidation products. Furthermore, the PCPE inhibited the MAPK/NF-κB signaling pathway, which resulted in anti-inflammatory and antioxidant effects on ALI-induced dogs. In the future, PCPE could be a useful ethnomedicine in veterinary clinical practices for the treatment of liver injuries or failures.

Abstract
Aflatoxin is an important toxicant of the fungal origin and poses a threat to the poultry industry. This study was designed to reveal the underlying mechanism and protective methods against aflatoxin B1 (AFB1)-induced liver injury, oxidative stress, and apoptosis using a Traditional Chinese medicine, Penthorum chinense Pursh extract (PCPE), in broilers. A total of 164 (day-old) broilers were equally allocated to the control, AFB1 (3 mg/kg feed), positive drug (Yin-Chen-Hao Tang extract, 10 ml/kg feed), PCPE (2 g PCPE/kg), and PCPE low, medium, and high dose groups (1 g, 2 g, 3 g PCPE/kg feed, respectively). AFB1 significantly decreased the growth performance and serum immunoglobulin level, altered normal serum biochemical parameters and antioxidant activities, and induced histopathological lesions in the liver as compared to control group. Additionally, AFB1 significantly up-regulated the mRNA expression levels of apoptosis-related genes such as Bax, Bak, caspase-9, caspase-3, and p53, whereas it down-regulated the expression levels of BCL2 in the liver of broilers. The supplementation of different doses of PCPE to AFB1-affected birds significantly eased AFB1 negative effects by improving growth performance, immunoglobulin level, and oxidative capacity, and reversed oxidative stress and pathological lesions in liver. Furthermore, supplementation of PCPE to the AFB1 group reversed apoptosis by significantly down-regulating the mRNA expression levels of Bax, Bak, caspase-9, caspase-3, and p53 and up-regulating the expression levels of BCL2 in the liver of broilers. Based on these results, we conclude that supplementation of PCPE is protective and safe against oxidative stress, is anti-apoptotic, and reverses the liver damage caused by AFB1 in broilers.

Abstract
Aflatoxin B1 (AFB1) is a carcinogenic mycotoxin widely present in foods and animal feeds; it represents a great risk to human and animal health. The aim of this study was to investigate the protective effects of Penthorum chinense Pursh compound (PCPC) against AFB1-induced damage, oxidative stress, and apoptosis via mitochondrial pathways in kidney tissues of broilers. One-day-old chickens (n = 180) were randomly allocated to six groups: control, AFB1 (2.8 mg AFB1/kg feed), positive drug (10 mLYCHT/kg feed), and PCPC high, medium, and low-dose groups (15, 10, and 5 ml PCPC/kg feed, respectively). AFB1 treatment reduced weight gain and induced oxidative stress and kidney damage in broiler tissues; however, PCPC supplementation effectively enhanced broiler performance, ameliorated AFB1-induced oxidative stress, and inhibited apoptosis in the kidneys of broilers. The mRNA expression levels of mitochondria-related apoptosis genes (Bax, Bak, cytochrome c, caspase-9, and caspase-3) were significantly increased, whereas BCL2 expression level decreased in the AFB1 group. Supplementation of PCPC to the AFB1 group significantly reversed the changes in mRNA expression levels of these apoptosis-associated genes compared to those in the AFB1 group. The mRNA levels of NRF2 and HMOX1 in the kidneys of the AFB1 group were significantly reduced compared to those in the control group, whereas PCPC significantly increased the NRF2 and HMOX1 mRNA levels. AFB1 decreased the levels of Beclin1, LC3-I, and LC3-II and increased P53 levels in the kidney compared to those in the control, whereas PCPC significantly reversed these changes to normal levels of autophagy-related genes compared to those in the AFB1 group. In conclusion, our findings demonstrated that PCPC ameliorated AFB1-induced oxidative stress by regulating the expression of apoptosis-related genes and mitochondrial pathways. Our results suggest that PCPC represents a natural and safe agent for preventing AFB1-induced injury and damage in broiler tissues.

Abstract
Abstract
Introduction
Cardiac computed tomography angiography (CCTA) derived fractional flow reserve (FFRCT) has been shown to add incremental diagnostic value by providing functional severity of coronary lesion in patients with coronary artery disease (CAD).
Purpose
We aimed to assess the prognostic value of FFRCT in patients with suspected CAD.
Methods
Consecutive patients who had clinically indicated CCTA and FFRCT determination at a tertiary care cardiology practice were included. FFRCT was determined off-site using computational flow dynamics. Patients were followed for major adverse cardiovascular events (MACE, inclusive of all-cause death, non-fatal myocardial infarction, and late percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) 90-days after imaging test.)
Results
A total of 667 patients with at least Coronary Artery Disease Reporting & Data System (CAD-RADS) 2 were included. Mean age was 68±10 years, 37% were women, 73% had hypertension, 12% had diabetes and 61% had dyslipidemia. More than half (57%) of the patients had moderate (CAD-RADS 3) stenosis. FFRCT<0.8 was found in 59% of patients, with increasing percent across categories of CAD-RADS. After a median follow-up of 9 months, 52 patients (7.2%, 6.7 events per 1000 person-year) experienced a MACE. In multivariable Cox regression models adjusted for age and sex, FFRCT <0.8 significantly predicted outcomes (HR 2.48 95% CI 1.26–4.87 p=0.008). Sensitivity analysis using lower thresholds of FFRCT failed to show similar results in intermediate stenosis.
Conclusion
Our results suggest that in a real-world cohort of patients with suspected CAD, FFRCT can identify patients at higher risk of incident cardiovascular outcomes.

Abstract
Abstract
Introduction
Cardiac computed tomographic angiography (CCTA)-derived measures of coronary artery disease (CAD) burden such as segment involvement score (SIS), which quantifies the number of segments with plaque, have been shown to independently predict incident cardiovascular events.
Purpose
We aimed to compare the added prognostic value of plaque burden to CCTA anatomic assessment and single photon emission computed tomography (SPECT) physiologic assessment in patients with diabetes undergoing both tests.
Methods
Consecutive patients with diabetes who underwent clinically indicated CCTA and SPECT myocardial imaging for suspected coronary artery disease at a tertiary care center were retrospectively identified from medical records. Stenosis severity and segment involvement score (SIS) were determined from CCTA, and presence of ischemia was determined from SPECT. Patients were followed from date of imaging for major adverse cardiovascular events (MACE; inclusive of all-cause death, non-fatal myocardial infarction, and percutaneous coronary intervention or coronary artery bypass grafting 90-days after imaging test.)
Results
A total of 778 patients were included (mean age 60.6±14.4 years, 55% males). Obstructive stenosis (left main ≥50%, all other coronary segments ≥70%) and ischemia were found in 15% and 16% of patients respectively. After a median follow-up of 31 months, 87 (11%) patients experienced a MACE. In multivariable Cox regression models, SIS significantly predicted outcomes in models including obstructive stenosis and ischemia (HR 1.17, 95% CI 1.10 - 1.24, p<0.001; 1.16, 95% CI 1.10 - 1.23, p<0.001). The addition of SIS also significantly improved discrimination (Harrel's C 0.75, p=0.006; 0.76, p=0.006 in models with CCTA obstructive stenosis and SPECT ischemia respectively). Results were consistent using subgroups of summed scores by composition of plaque (calcified vs non-calcified) and alternate definitions of obstructive stenosis.
Conclusion
Our results suggest that in high-risk patients with diabetes and suspected coronary disease, SIS has incremental prognostic value over ischemia by SPECT or stenosis by CCTA in predicting incident cardiovascular outcomes.

Background
Coronary computed tomography angiography (CCTA) is currently guideline-endorsed for diagnosing suspected coronary artery disease (CAD) in low-intermediate risk patients. Single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) has an established role in both the accurate detection of ischemia and identification of patients at high risk of future cardiovascular events. Recent studies have shown that the burden of atherosclerotic plaque is an independent predictor of cardiovascular events, and that this effect depends on the degree of calcification.
Purpose
To compare the incremental prognostic value of calcified vs non-calcified plaque burden to CCTA anatomic assessment and SPECT physiologic assessment in patients evaluated with both tests.
Methods
Consecutive patients who underwent clinically indicated CCTA and SPECT myocardial imaging for suspected CAD were included. Ischemia on SPECT was defined as summed difference score > 0 using perfusion graded on a 5-point scale. Anatomically obstructive CAD by CCTA was defined as ≥50% in the left main artery and ≥70% stenosis severity in proximal, mid and distal branches of the left anterior descending, left circumflex and right coronary artery without including side branches. Segment involvement score was defined as the sum of segments with plaque irrespective of the degree of stenosis using an 18-segment coronary artery model. A Hounsfield unit threshold of > =130 was used to classify plaques composition as calcified/mixed (C-SIS) vs non-calcified plaque (NC-SIS). Patients were followed for major adverse cardiovascular events (MACE, inclusive of all-cause death, non-fatal myocardial infarction, and percutaneous coronary intervention or coronary artery bypass grafting 90-days after imaging test.)
Results
A total of 956 patients were included. (Mean age 61.1 ± 14.2 years, 54% men, 89% hypertension, 81% diabetes, 84% dyslipidemia). Obstructive stenosis (left main ≥ 50%, all other coronary segments ≥ 70%) and ischemia were observed in similar number of patients (14%). After a median follow-up of 31 months, 102 patients (11%, 29.2 events per 1000 person-year) experienced a MACE.

Background
Advances in computed tomography (CT) and machine learning have enabled on-site non-invasive assessment of fractional flow reserve (ML-FFRCT). However, reproducibility of measurements across operators is not well demonstrated.
Purpose
This study was designed to measure the inter-operator variability and reproducibility of Coronary CT Angiography–derived fractional flow reserve values using a post-processing prototype based on a machine learning algorithm (ML-FFRCT).
Methods
We included 60 symptomatic patients who underwent coronary CT angiography. FFRCT was calculated by 2 independent operators after training using a machine learning based on-site prototype. FFRCT was measured 1 cm distal to the coronary plaque or in the middle of the segments if no coronary lesions were present. Intraclass correlation coefficient (ICC) and Bland-Altman analysis were used to evaluate inter-operator variability effect in FFRCT estimates. Sensitivity analysis was done by cardiac risk factors, degree of stenosis and image quality.
Results
A total of 535 coronary segments in 60 patients were assessed. The overall ICC was 0.986 per patient (95% CI: 0.977 - 0.992) and 0.972 per segment (95% CI: 0.967 - 0.977). The absolute mean difference in FFRCT estimates was 0.012 per patient (95% CI for limits of agreement: -0.035 - 0.039) and 0.02 per segment (95% CI for limits of agreement: -0.077 - 0.080). Tight limits of agreement were seen on Bland-Altman analysis. Distal segments had greater variability compared to proximal/mid segments (absolute mean difference 0.011 vs 0.025, p < 0.001). Sensitivity analysis showed similar results across degrees of stenosis, image quality and those with cardiac risk factors such as hypertension, diabetes and dyslipidemia.
Conclusion
A high degree of inter-operator reproducibility can be achieved by onsite machine learning based ML-FFRCT assessment. Future research is required to evaluate the physiological relevance and prognostic value of ML-FFRCT.

Abstract
Pathogenicity of tibial dyschondroplasia (TD) in broiler chickens is not detected yet. Janus Kinase/Signal Transducer and Activator of Transcription (JAK-STAT) signaling pathway-related genes were investigated in thiram induced TD chickens. Real-time qPCR and immunohistochemical (IHC) technique were used to observe the expression changes of STAT3 and SOSC3 gene on days 1, 2, 4, 6 after feeding 100 mg·kg-1 thiram. Morphological, pathological, and histological results of this study suggested that chondrocyte cells were observed more damaged on day 6 than day 1, 2, and 4. Therefore, Lameness and damaged chondrocytes gradually increased from day 1 to 6. The mRNA expression level of STAT3 was observed insignificant (P > 0.05) in thiram induced TD chickens' group of day 1. However, on days 2, 4, and 6, the expression was significant (P < 0.05). SOCS3 increased in thiram group on days 1, 2 and 6, decreased on day 4 (P < 0.05). The p-STAT3 and SOCS3 protein's protein localization was evaluated in the control and thiram-induced TD broiler chickens through IHC, suggesting that SOSC3 protein was observed significantly higher on days 1, 2, and 6 and down-regulated on day 4. p-STAT3 protein on thiram induced group was observed significantly upregulated on days 4 and 6. In conclusion, the differential expression of STAT3 and SOCS3 showed that the JAK-STAT signaling pathway might play an important role in regulating an abnormal proliferation, differentiation, or apoptosis of chondrocytes in TD at an early stage.

Abstract
Carotenoids are one of the widespread and ubiquitous lipid-soluble pigments that produce a wide range of colours which are universally found in various plants, microalgae, bacteria and fungi. Recently, interest in using carotenoids as feed ingredients has increased markedly owing to their bioactive and health-promoting properties. In terms of applications, carotenoid-rich products are widely available in the form of food and feed additive, supplements and natural colourants. Carotenoids play a versatile biological role that contributes to therapeutic effects, including anticancer, immunomodulators, anti-inflammatory, antibacterial, antidiabetic and neuroprotective. Dietary supplementation of carotenoids not only improves the production performance and health of poultry birds, but also enhances the quality of egg and meat. Several studies have suggested that the supplementation of plant derived carotenoids revealed numerous health-promoting activities in poultry birds. Carotenoids reduce the oxidative stress in pre-hatched and post-hatched birds through different mechanisms, including quench free radicals, activating antioxidant enzymes and inhibiting the signalling pathways. Use of carotenoids in poultry feed as a part of nutrient that confers bird health and improve product quality. Carotenoids play a critical role for the pigmentation of egg yolk, skin, legs, beak, comb, feather and fat. Birds consumed carotenoid deficient diet resulting hues of their egg yolk or pale coloured skin. Therefore, uniform pigmentation generally indicates the health status and quality of the poultry products. This review aims to gather recent information regarding bioactive properties of carotenoids and highlight pharmaceutical and health beneficial effects of carotenoids for the poultry industry. Additionally, it explores the importance of carotenoids as alternative feed ingredients for poultry to boost the production performance and replace synthetic medicine and nutrients.

Abstract
This study aims to determine the comparative haematological parameters and to check possible physiological changes among blood parameters of domestic cats living at high- and low-altitude regions of China. For this purpose, blood samples were randomly collected from healthy semi-long-haired Tonkinese cats in Tibet (high altitude) and Zhejiang (low altitude) regions of China. The results of present study showed that RBCs, HGB, MCH and MCHC values of Tibetan Tonkinese cats were significantly (p < .01) higher as compared to Zhejiang Tonkinese cats. However, MCV values of Tibetan Tonkinese cats were significantly lower (p < .01) as compared to Zhejiang cats. In addition, there was no significant difference among HCT values of both Tibetan and Zhejiang cats. Therefore, it was concluded that Tibetan cats had adapted the high-altitude environment of Tibet by acquiring high concentration of RBCs, HGB, MCH and MCHC, while decreased concentration of MCV content in their blood. This is the first report describing the comparative haematological parameters of Tibetan and Zhejiang Tonkinese cats living at high and low altitudes, respectively. This study provides reference values of the different blood parameters, which can be used as an important marker for the diagnosis of various diseases and utilizing in further animal research.

Abstract
Tibial dyschondroplasia (TD) is a bone defect of broilers and other poultry birds that disturbs growth plate and it causes lameness. Previously we evaluated differential expression of multiple genes involved in growth plate angiogenesis and reported the safety and efficacious of medicinal plant root extracted for controlling TD. In this study, clinical and protective effect of an antibiotic Novobiocin (Hsp90 inhibitor) and expression of Hsp90 and proteoglycan aggrecan was examined. The chicks were divided into three groups; Control, thiram-induced TD, and Novobiocin injected TD. After the induction of TD, the Novobiocin was administered through intraperitoneal route to TD-affected birds until the end of the experiment. The expressions and localization of Hsp90 were evaluated by qRT-PCR, immunohistochemistry (IHC) and western blot, respectively. Morphological, histological examinations, and serum biomarker levels were evaluated to assess specificity and protective effects of Novobiocin. The results showed that TD causing retarded growth, enlarged growth plate, distended chondrocytes, irregular columns of cells, decreased antioxidant capacity, reduced protein levels of proteoglycan aggrecan, and upregulated in Hsp90 expression (p < 0.05) in dyschondroplastic birds as compared with control. Novobiocin treatment restored growth plate morphology, reducing width, stimulated chondrocyte differentiation, sprouting blood vessels, corrected oxidative imbalance, decreased Hsp90 expressions and increased aggrecan level. Novobiocin treatment controlled lameness and improved growth in broiler chicken induced by thiram. In conclusion, the accumulation of the cartilage and up-regulated Hsp90 are associated with TD pathogenesis and irregular chondrocyte morphology in TD is along with reduced aggrecan levels in the growth plate. Our results indicate that Novobiocin treatment has potential to reduce TD by controlling the expression of Hsp90 in addition to improve growth and hepatic toxicity in broiler chicken.

Abstract
Copper is the most essential trace element in the animal body. Nano-sized copper particles have been widely used in a number of different animal species in modern medicinal practice. The present study was designed to examine the effect of dietary copper sulfate/(CuSO4) and nano copper supplementation on serum antioxidant capacity of weaning piglets. A total of 28 Duroc piglets (21 days, and weighing ~7 kg) were randomly divided into three equal groups. The control group (n=4) was administered with a normal standard diet; however the CuSO4 (n=12) and nano copper (n=12) groups were treated with 50, 100 and 200 mg/kg/day body weight, respectively. After 28 days, blood serum copper-zinc superoxide dismutase (CuZn-SOD), ceruloplasmin (CP), malondialdehyde (MDA), myeloperoxidase (MPO), total antioxidant capacity (T-AOC), peroxidase (POD), nitric oxide (NO), nitric oxide synthase (NOS), hydrogen peroxide (H2O2) and inhibition of hydroxyl radical (CIHR) were analyzed from all groups. The results indicated that nano copper supplementation has significant (P less than 0.05) effect on the serum antioxidant capability as compared to dietary CuSO4 group in weaned piglets. Nano-size copper 100 mg/kg/day supplementation was confirmed to improve the immunity level by strengthening the antioxidant capacity of weaning piglets. Dietary supplementation with 100 mg/kg body weight nano copper could be a potential substitute for weaned piglets.

Abstract
Tibial dyschondroplasia (TD) is main bone problem in fast growing poultry birds that effect proximal growth plate (GP) of tibia bone. TD is broadly defined as non-vascularized and non-mineralized, and enlarged GP with tibia bone deformation and lameness. Icariin (Epimedium sagittatum) is a traditional Chinese medicine, which is commonly practiced in the treatment of various bone diseases. Recently, many researcher reports about the beneficial effects of icariin in relation to various types of bone conditions but no report is available about promoting effect of icariin against TD. Therefore, current study was conducted to explore the ameliorating effect of icariin in thiram-induced TD chickens. A total of 180 broiler chicks were equally distributed in three groups; control, TD induced by thiram (50 mg/kg), and icariin group (treated with icariin @10 mg/kg). All groups were administered with normal standard diet ad libitum regularly until the end of experiment. The wingless-type member 4 (WNT4) and vascular endothelial growth factor (VEGF) genes and proteins expression were analyzed by quantitative real-time polymerase chain reaction and western blot analysis respectively. Tibial bone parameters, physiological changes in serum, antioxidant enzymes, and chicken growth performance were determined to assess advantage and protective effect of the medicine in broiler chicken. The expression of WNT4 was decreased while VEGF increased significantly (P < 0.05) in TD affected chicks. TD enhanced the GP, lameness, and irregular chondrocytes, while reduced the liver function, antioxidant enzymes in liver, and performance of chickens. Icariin treatment up-regulated WNT4 and down-regulated VEGF gene and protein expressions significantly (P < 0.05), restored the GP width, increased growth performance, corrected liver functions and antioxidant enzymes levels in liver, and mitigated the lameness in broiler chickens. In conclusion, icariin administration recovered GP size, normalized performance and prevented lameness significantly. Therefore, icariin treatments are encouraged to reduce the incidence of TD in broiler chickens.

Abstract
Background Pseudorabies (PR) is an important emerging infectious disease that is characterized by fever, extreme itching and encephalomyelitis. However, it is still unclear whether Tibetan pigs are exposed to Pseudorabies virus (PRV) or not. The present study was conducted to investigate the seroprevalence of PRV infection in Tibetan pigs in Nyingchi area of Tibet through enzyme-linked immunosorbent assay (ELISA). A total of 368 serum samples from Tibetan pigs were collected during 2015. Results Results showed that 58 (15.76%) samples were found positive for PRV antibodies with further distribution of 18.23%, 13.42% and 6.25% from Nyingchi, Mainling and Gongbo’gyamda areas on the Tibetan plateau, respectively; along with 12.10%, 17.71% and 17.57% prevalence of PRV in juveniles, sub-adults and adults, respectively. The prevalence of PRV infection between male (14.61%) and female (16.84%) showed non-significant difference (P > 0.05). The risk factors of infection were found to be associated with feed type, age and altitude. Conclusions The present study depicts a serious concern with a new emerging infectious disease in Tibetan pigs in Tibet, China.

Abstract
Nano-sized copper particles are widely used in various chemical, physical, and biological fields. However, earlier studies have shown that nano copper particles (40-100 μg/mL) can induce cell toxicity and apoptosis. Therefore, this study was conducted to investigate the role of nano copper in mitochondrion-mediated apoptosis in PK-15 cells. The cells were treated with different doses of nano copper (20, 40, 60, and 80 μg/mL) to determine the effects of apoptosis using acridine orange/ethidium bromide (AO/EB) fluorescence staining and a flow cytometry assay. The levels of malondialdehyde (MDA) and superoxide dismutase (SOD) in the PK-15 cells were examined using commercially available kits. Moreover, the mRNA levels of the Bax, Bid, Caspase-3, and CYCS genes were assessed by real-time PCR. The results revealed that nano copper exposure induced apoptosis and changed the mitochondrial membrane potential. In addition, nano copper significantly altered the levels of the Bax, Bid, Caspase-3, and CYCS genes at a concentration of 40 μg/mL. To summarize, nano copper significantly (P < 0.05) decreased the level of SOD and increased the level of MDA in PK-15 cells. Altogether, these results suggest that nano copper can play an important role in inducing the apoptotic pathway in PK-15 cells, which may be the mechanism by which nano copper induces nephrotoxicity.

Abstract
Tibial dyschondroplasia (TD) is a disease of many avian species characterized by an enlarged and avascular lesion in the proximal tibiotarsal bone. The aim of present study was to evaluate the effects of hypoxia-inducible factor-1α(HIF-1α) inhibition on thiram- induced TD using synthetic medicine FK228 and the association between HIF-1α and heat-shock protein 90 (Hsp90). One hundred and fifty broiler chicks were equally divided into 3 groups: control; thiram fed; and FK228 treatment. Expressions of HIF-1α and Hsp90 genes were analyzed by real-time quantitative polymerase chain reaction (RT-qPCR) on day 10 and 14 post-hatch. Western blot analysis of HIF-1α and Hsp90 gene was performed to measure the protein levels at the end of the experiment. Results showed that HIF-1α and Hsp90 levels were significantly (P less than 0.05) up-regulated in the thiram group as compared to the control group. Meanwhile, FK228 (HIF-1α inhibitor) significantly (P less than 0.05) down- regulated the mRNA and protein levels of HIF-1α and Hsp90, restored the size of growth plate and diminished lameness. In conclusion, HIF-1α and Hsp90 play an important role in the formation of avascular growth plate and there is a direct relationship between HIF-1α and Hsp90 for the progression of TD pathogenesis. Therefore, HIF- 1α may prevent and control TD in broiler chickens.

Abstract
The nano copper has been widely used in modern clinical medicine practice. However, it has been noticed that nano copper particles induce cell injury and toxicity. The present study was designed to determine the effect of nano copper particles on cell injury of intestinal epithelial cells (IECs) in piglets. The IECs were treated with different doses of nano copper (5, 10, 20 and 40μg/ml) for 24-48h to observe cell injury and toxicity. Cell injury was measured based on morphological and other changes including oxidative stress and genes expression. The oxidative stress markers were assayed by differential expression levels of SOD, MDA and Metallothionein (MT) in addition to CTR1, SOD1, COX17, MT and ATOX1 genes expression. Cellular morphology showed an increasing growth of cells without nano copper treatment and nano copper showed significant damage to IECs with higher dose as compared to low dose. Higher doses of copper nanoparticles (10, 20 and 40μg/ml) have membrane damaging effect on the intestinal epithelial cells, whereas MDA contents and MT value were significantly increased, and SOD activity was decreased with the increase in concentration of nanoparticles. Nano copper up-regulated the CTR1 and SOD1 genes and down-regulated the relative expression of COX17, MT and ATOX1 genes significantly in a dose-dependent manner. The findings of the current study provide important insights that nano copper plays an important role in intestinal epithelial cell injury and oxidative stress.

Abstract
This study was undertaken to investigate drug resistance in Escherichia
coli (E. coli) strains isolated from bamboo rats in Zhejiang
province of China. One hundred and fifty-four E. coli strains were
isolated from dead bamboo rats. Polymerase chain reaction (PCR) was used to detect the
representative genes encoding resistance to commonly used β-lactam antibiotics. Highest
resistance was observed for cefradine (24.03%), followed by penicillin (20.78%) and
ceftazidime (20.13%). The isolation rates of β-lactam resistance genes were 53.25, 48.70,
15.58 and 14.29% for bla TEM, bla
CTX-M, bla OXA and bla
SHV, respectively, while 62 (40.26%) E. coli
isolates harbored multiple β-lactam resistance genes. These results also suggested that
long term use of these antibiotics leads to antibimicrobial resistance. We believe that
this study will provide a guideline for veterinarians and a research basis for examining
resistance-encoding genes in other food animals like bamboo rats.

Abstract
The present study was designed to investigate the hypothesis that in vivo entosis is a novel pathway for eliminating spermatozoa in the seminiferous tubules (ST) during hibernation of the Chinese soft-shelled turtle. Western blot analysis revealed that the expression of LAMP1 in the testis was significantly higher during hibernation than that during non-hibernation. Immunohistochemistry reaction showed that LAMP1-positive substance was distributed within the Sertoli cells of the testis. Further examination by transmission electron microscopy (TEM), many degraded spermatozoa being enwrapped within large entotic vacuoles in Sertoli cells. The nucleus and the flagellum of the spermatozoa were shown to be decomposed and digested inside entotic vacuoles within Sertoli cells. More than two spermatozoa heads were always observed in each internalized vacuoles. Deserving note is that, a number of different autophagosomes, including initial autophagic vesicles and degradative autophagic vesicles were found inside the entotic vacuoles of the Sertoli cells during hibernation. At the end of hibernation, entotic vacuoles and their autophagosomes disappeared, and numerous large lipid droplets (LDs) appeared within the Sertoli cells. Adherens junctions were apparent between Sertoli cells and developing germ cells, which is the ultrastructural basis of entosis. Taken together, the results presented here show that in the turtle: (1) entosis with internal autophagosomes can take place within normal body cells during hibernation; (2) spermatozoa, as a highly differentiated cell can be internalized and degraded within Sertoli cell by entosis in vivo, which is in favor of the next reproductive cycle in the turtle.

Abstract
Tibial dyschondroplasia (TD) is one of the most common problems in the poultry industry and leads to lameness by affecting the proximal growth plate of the tibia. However, due to the unique environmental and geographical conditions of Tibet, no case of TD has been reported in Tibetan chickens (TBCs). The present study was designed to investigate the effect of high altitude hypoxia on blood parameters and tibial growth plate development in chickens using the complete blood count, morphology, and histological examination. The results of this study showed an undesirable impact on the overall performance, body weight, and mortality of Arbor Acres chickens (AACs) exposed to a high altitude hypoxic environment. However, AACs raised under hypoxic conditions showed an elevated number of red blood cells (RBCs) and an increase in hemoglobin and hematocrit values on day 14 compared to the hypobaric normoxia group. Notably, the morphology and histology analyses showed that the size of tibial growth plates in AACs was enlarged and that the blood vessel density was also higher after exposure to the hypoxic environment for 14 days, while no such change was observed in TBCs. Altogether, our results revealed that the hypoxic environment has a potentially new role in increasing the blood vessel density of proximal tibial growth plates to strengthen and enhance the size of the growth plates, which may provide new insights for the therapeutic manipulation of hypoxia in poultry TD.

Abstract
BACKGROUND & OBJECTIVES Culex tritaeniorhynchus is the primary vector of Japanese encephalitis virus (JEV) which is a major threat to animals and humans health. This virus has been reported earlier from low altitude regions of Tibet, in mosquitoes, Tibetan pigs and local Tibetans, but no reports are available for the probable propagation of JE to high altitude regions (3100 m) of Tibet. This study aimed to find the evidence of JEV in Cx. tritaeniorhynchus and pigs from high altitude regions of Tibet, China. METHODS In total, 102 porcine serum samples and eight pools of Cx. tritaeniorhynchus were subjected to real-time PCR (RT-PCR) for the amplification of a fragment (~ 420 bp) of the NS1 gene. The resultant amplicons of the genes were subsequently analyzed and sequenced. RESULTS Overall seroprevalence of JE in Tibetan pigs was 6.86%, while five pools of Cx. tritaeniorhynchus were found positive for JEV. Results showed genotype III as the most prevalent (100%) among JEV positive isolates. Furthermore, phylogenetic analysis of the JEV positive strains showed 98.8-99% similarity to four reference strains from China (JEV-Hubei, Whe, HYZ and CQ11-66). INTERPRETATION & CONCLUSION The present study revealed that JEV has extended its geographic range to high altitude regions of Tibet. The factors like increased tourism and transportation might play key role in the transmission of JE that comprises a potential health risk for humans and animals.

Abstract
Diarrhea is one of the main causes of animal deaths especially in neonatal calves. The objective of this study was to investigate the blood serum for cobalt (Co), copper (Cu), iron (Fe), magnesium (Mg), manganese (Mn), Molybdenum (Mo), selenium (Se), and zinc (Zn) concentrations in yak serum samples by inductively coupled plasma mass spectrometry (ICP-MS) from 35 yaks consisting of 10 healthy and 25 diarrheic ones. Our observations indicated that the concentrations of Mn, Zn, and Fe in yak affected with diarrhea had statistically significant reduced levels as compared to the control group (P < 0.05). The mean concentration of Cu in blood serum of diarrheic yaks was found significantly higher than the normal ones (P < 0.05). The Mn and Zn in the serum of diarrheic groups were observed significantly different (P < 0.05) with different ages. These findings can provide for some valuable information for the investigation on relationship between trace elements in the serum of normal and diarrheic yaks.
