Abstract
Shaanxi Province is an important agricultural province in western China. Its profit-oriented management of crop residues remains a concern in the agriculture sector. Aiming to accelerate the valorization of agricultural straw and offer potential solutions for profit-oriented use of crop residues in Shaanxi, this study estimated the quantity of resources and collectable amount of crop straw by using the grain-to-straw ratio, analyzed the carbon emission reduction potential considering biochar energy and soil uses with the help of a life cycle assessment (LCA) model, and calculated the economic benefits of biochar production using waste and abandoned straw in Weinan (a city of Shaanxi). The theoretical resources and collectible amount of crop straw in Shaanxi showed an overall growth trend from 1949 to 2021, reaching 1.47 × 107 and 1.26 × 107 t in 2021 respectively. In 2021, straw from corn, wheat, and other grains accounted for 94.32% of the total straw. Among the 11 cities in Shaanxi, Weinan had the largest straw resources of 2.82 × 106 t, Yulin had the largest per capita straw resources of 0.72 t/person, and Yangling had the highest resource density of 7.60 t/hm2. The total carbon emission reduction was 3.11 × 104 t under scenario A with crop straw used for power generation. The emission reduction ranged from 1.25 × 107 to 1.27 × 107 CO2e t under scenario B with biochar production for energy and soil use. By using waste and abandoned straw in Weinan for biochar production, carbon emissions could be reduced by up to 2.07 × 105 t CO2e. In terms of the economic benefit from straw pyrolysis, the actual income was estimated to range from 0.67 × 108 to 1.33 × 108 ¥/a with different carbon prices. This study sheds light on the economic and environmental benefits of agricultural straw valorization through pyrolysis in Shaanxi, and provided an important basis for promoting the agricultural straw utilization in view of its potential for carbon emission reduction.

Abstract
Objective: To investigate the clinicopathological features, diagnosis and differential diagnosis of adrenal cortical carcinoma (ACC) in children. Methods: Twenty-five children with ACC diagnosed in the Department of Pathology, Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine, Shanghai, China from March 2014 to August 2022 were retrospectively analyzed. The related literature was reviewed. Results: A total of 25 children with ACC were collected, including 11 males and 14 females, with a male to female ratio of 1.0∶1.3. The patient ages ranged from 8 months to 14 years (median, 4 years). Eighteen cases with clinical data had functional tumors (18/22, 81.8%) presenting with virilization or precocious puberty (15/18), symptoms related to hypercortisolism (8/18) or endocrine symptoms mixed with both (5/18), while 3 cases (3/22, 13.6%) had unknown clinical data. The clinical manifestations of four patients with nonfunctional tumors were an abdominal mass and/or abdominal pain, walking instability and others. Grossly, the average maximum diameter of the tumor was 9.4 cm. Most of the tumors were nodular and partially encapsuled. The cut surfaces were gray or gray brown, soft with hemorrhage. Histologically, the tumor cells were diffusely distributed, separated by a vascular-rich network. The tumor cells were large, with distinct nucleoli, abundant eosinophilic or clear cytoplasm, and round or oval nuclei. The mitotic index was high, and atypical mitoses were common. Necrosis, calcification, capsule invasion or/and venous invasion were present. In some cases, the tumor invaded the surrounding soft tissues or kidneys. Immunohistochemically, the tumor cells were diffusely positive for syn and SF1 and focally positive for α-inhibin, Melan A and Calretinin, but negative for CgA. Ki-67 proliferation index ranged from 2%-90%. TP53 gene status was examined in 7 cases, in which mutations were detected in 4 cases. Follow-up data was obtained in 21 patients, among whom 18 received chemotherapy and 3 received radiotherapy. Distant metastasis occurred in 13 patients. Median progression-free survival (PFS) was 11.2 months and median overall survival (OS) was 54.7 months. Patients aged less than 5 years had a better prognosis for OS (P<0.05) than the older ones (≥5 years), but a similar PFS (P>0.05). Male patients and Ki-67 proliferation index <15% had a better prognosis tendency for OS, but there was no statistically significant difference (P>0.05). Conclusions: ACC in children is a rare, often functional tumor associated with Li-Fraumeni genetic syndrome and has a poor prognosis. Diagnosis and differential diagnosis require a combination of morphological, phenotypic and clinical analysis.

Abstract
The viscosity distribution of micellar interiors from the very center to the outer surface is dramatically varied, which has been distinguished in theoretical models, yet it remains highly challenging to quantify this issue experimentally. Herein, a series of fluorophore-substituted surfactants DPAC-Fn (n = 3, 5, 7, 9, 11, 13, and 15) are developed by functionalizing the different alkyl-trimethylammonium bromides with the butterfly motion-based viscosity sensor, N,N'-diphenyl-dihydrodibenzo[a,c]phenazine (DPAC). The immersion depth of DPAC units of DPAC-Fn in cetrimonium bromide (C16TAB) micelles depends on the alkyl chain lengths n. From deep (n = 15) to shallow (n = 3), DPAC-Fn in C16TAB micelles exhibits efficient viscosity-sensitive dynamic multicolor emissions. With external standards for quantification, the viscosity distribution inside a C16TAB micelle with the size of ∼4 nm is changed seriously from high viscosity (∼190 Pa s) in the core center to low viscosity (∼1 Pa s) near the outer surface. This work provides a tailored approach for powerful micelle tools to explore the depth-dependent microviscosity of micellar interiors.

Abstract
PURPOSE/OBJECTIVE(S) Novel treatment combinations are required to increase response rates in rectal cancer. EnAd is an intravenous, tumor selective, oncolytic adenovirus with high affinity for malignant colorectal epithelial cells. Pre-clinical evidence of synergy with radiation warranted further clinical evaluation and assessment of safety in combination with chemoradiation (CRT), 25 × 2Gy and concurrent capecitabine. MATERIALS/METHODS EnAd was escalated using 2 dose levels of viral particles (1 × 1012, 3 × 1012), given Monday, Wednesday, Friday over 3 schedules (pre-CRT, pre & post CRT). Toxicity and efficacy were used as dual end points in escalation decisions. A 2-parameter and 3-parameter logistic Time to Event Continual Reassessment Method (TiTE-CRM) were used estimate the dose-toxicity and dose-efficacy relationship, respectively. Results are shown as probability and 95% credible interval (Cr.I). The dose limiting toxicity (DLT) window was 13 weeks. Patients who had not completed their DLT window at the time of a dose decision were included in the safety analysis but down-weighted according to their follow-up time and amount of IMP received. Efficacy was assessed at 13 weeks using MRI Tumor Regression Grade (mrTRG), where mrTRG 1-2 equals response. The trial (NCT03916510) was conducted in 4 UK centers. RESULTS A total of 13 patients were enrolled, 12 of whom were evaluable. Median age was 57 (range 31-84), and 10/13 were male. One patient had two G3 adverse events (AE); diarrhea, acute kidney injury. All other adverse events (AEs) were G1 or 2, with no G4/5 events. The most common AE by organ system was gastrointestinal (20.8%, G1). There were two observed DLTs on Dose schedule 3; leg swelling and acute kidney injury. Responses and toxicities increased with escalating schedules of EnAd (Table 1). CONCLUSION CEDAR is the first trial to successfully combine an intravenous oncolytic adenovirus with radiation, demonstrating the feasibility and acceptability of this approach, and a new paradigm in radiosensitization in rectal cancer. Within this small Phase I study, EnAd demonstrated an acceptable safety profile with evidence of a higher-than-expected rate of response by mrTRG. Translation analysis of tissue, blood and microbiome for biological correlates of radiation synergy is underway. FUNDING PsiOxus, CRUK (A24474). SPONSOR University of Oxford.

Abstract
Purpose To investigate the effect of sleep disorder (SD) on the changes of brain network dysfunction in mild cognitive impairment (MCI), we compared network connectivity patterns among MCI, SD, and comorbid MCI and sleep disorders (MCI-SD) patients using resting state functional magnetic resonance imaging (RS-fMRI). Patients and Methods A total of 60 participants were included in this study, 20 each with MCI, SD, or MCI-SD. And all participants underwent structural and functional MRI scanning. The default-mode network (DMN) was extracted by independent component analysis (ICA), and regional functional connectivity strengths were calculated and compared among groups. Results Compared to MCI patients, The DMN of MCI-SD patients demonstrated weaker functional connectivity with left middle frontal gyrus, right superior marginal gyrus, but stronger connectivity with the left parahippocampus, left precuneus and left middle temporal gyrus. Compared to the SD group, MCI-SD patients demonstrated weaker functional connectivity with right transverse temporal gyrus (Heschl’s gyrus), right precentral gyrus, and left insula, but stronger connectivity with posterior cerebellum, right middle occipital gyrus, and left precuneus. Conclusion Patients with MCI-SD show unique changes in brain network connectivity patterns compared to MCI or SD alone, likely reflecting a broader functional disconnection and the need to recruit more brain regions for functional compensation.

Abstract
AIMS The purpose of this experiment was to study the bacterial diversity of traditional fermented sausages from four typical regions of China (Chengdu, Shenzhen, Changsha and Harbin) and to further evaluate their microbiological safety. METHODS AND RESULTS The diversity of the microbiota of the sausages was studied using the Illumina HiSeq platform. The results showed that compared with the highest diversity of fermented bacteria in Guangdong, the bacterial diversity of fermented sausage was the lowest in Sichuan. The percentage of dominant phylum (Firmicutes, Cyanophyta, Proteobacter) were 78·39, 13·13 and 7·14% in SC, 35·47, 30·36 and 28·04% in GD, 54·81, 28·91 and 14·00% in HN, 20·20, 58·16 and 17·31% in HB respectively. The main genus distribution of fermented sausages in different regions is varied, but lactic acid bacteria and cyanobacteria are generally the main ones. Traditional fermented sausages using natural fermentation methods have poor microbiological safety, and pathogenic and spoilage micro-organisms such as Acinetobacter, Brochothrix and Pseudomonas have been detected in all four regions. CONCLUSIONS The results in this paper provide a microbiota profile of four typical fermented sausages in China. There is a big difference in the microbiota of sausages in different regions, and the good flavour of traditional Chinese fermented sausage is related closely with the abundant microbial resources, however, the natural fermentation method also expose to the product security threats, including spoilage, pathogenic micro-organisms and biogenic amines, etc. SIGNIFICANCE AND IMPACT OF THE STUDY: The results would offer guidance for industrial fermented sausage production with certain flavour and also improve the microbial resource utilization, and contribute to the control of harmful micro-organisms in traditional fermented sausage.

Abstract
OBJECTIVE Acute lung disease is characterized by inflammation. This research aimed to investigate effect of trichostatin A (TSA) on microRNA-146a (miR-146a) and tumor necrosis factor α (TNF-α) in lipopolysaccharide (LPS)-induced alveolar macrophage injury model. MATERIALS AND METHODS Rat alveolar macrophage, NR8383, was cultured and induced using LPS to establish acute lung injury model in vitro level. Cell Counting Kit-8 (CCK-8) assay was used to determine cell viability of NR8383 cells. TSA was administrated to LPS-induced NR8383 cells. Quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR) assay was utilized to evaluate TNF-α and miR-146a mRNA expression in LPS and/or TSA treated NR8383 cells. Enzyme-link immunosorbent assay (ELISA) was used to examine TNF-α levels. RESULTS This study selected 1 ng/ml and 10 ng/ml TSA as the optimal concentrations for treating NR8383 cells. LPS-induced acute lung injury model was successfully established. TSA administration significantly enhanced accounts of LPS-stimulated NR8383 cells. LPS induction significantly increased miR-146a mRNA expression in NR8383 cells compared to NR8383 cells (p<0.05). TSA administration significantly reduced the levels of TNF-α in LPS-induced NR8383 cells compared to those in LPS-induced NR8383 cells (p<0.05). TSA administration significantly enhanced miR-146a expression in LPS-induced NR8383 cells compared to that in LPS-induced NR8383 cells (p<0.05). CONCLUSIONS TSA administration exerted anti-inflammation functions in LPS-induced acute lung injury model in vitro, which might be triggered by inhibiting TNF-α molecule and upregulating miR-146a expression. The present data hint that TSA could be considered as a potential therapeutic agent for treating acute lung injury.

Abstract
Objective: To investigate the change of esophageal length measured on computed tomography after C(7) pedicle subtraction osteotomy (PSO) for cervicothoracic kyphosis in ankylosing spondylitis (AS) patients and its clinical significance. Methods: Eight male AS patients with cervicothoracic kyphosis, who underwent PSO at C(7) level from December 2014 to November 2018 at Nanjing Drum Tower Hospital, were retrospectively reviewed. The mean age was (35±7) years (range, 26-49 years). The cervicothoracic kyphosis, C(2)-T(1) sagittal vertical axis (SVA) and angle of fusion levels (AFL) were measured on lateral cervical radiographs and chin-brow vertical angle (CBVA) was measured on clinical photographs preoperatively and postoperatively. Anterior height of the osteotomized vertebra (AHOV) and esophageal length from the lower endplate of C(6) to the inferior endplate of the lower instrumented vertebrae were measured on sagittal plane of reconstructed computed tomography preoperatively and postoperatively. Oswestry Disability Index (ODI), Neck Disability Index (NDI) and Numerical Rating Scale (NRS) were collected to evaluate the clinical outcomes. Results: The average follow-up duration was (15±9) months (range, 3-51 months). The average correction of cervicothoracic kyphosis, C(2)-T(1)SVA, AFL and CBVA was 35.9°±7.3°, (44.7±11.6) mm, 32.0°±4.8° and 38.1°±11.5°, respectively. The average reduction of AHOV was (5.6±1.6) mm. ODI was improved from 17±14 preoperatively to 13±10 at the final follow-up. The NDI before operation and at the final follow-up was 18±15 and 10±6, respectively. The preoperative NRS was 4.8±2.4, and it decreased to 1.0±1.2 at the final follow-up. The change of esophageal length showed significant correlation with the improvement of cervicothoracic kyphosis, C(2)-T(1)SVA, AFL and CBVA(r=0.84, 0.83, 0.83, 0.73, all P<0.05). Conclusions: The operation of C(7)PSO increases esophageal length after cervicothoracic kyphosis in AS patients. The esophageal elongation is closely related with changes of parameters measured on radiographs and clinical photographs. Spine surgeons should be aware of the potential risk of esophagus-related complications caused by esophagus lengthening after C(7)PSO.

Abstract
BACKGROUND The extensive involvement of microRNAs (miRNAs) in the pathogenesis of psoriasis is well documented. However, little is known about the contribution of specific miRNAs to the prevalence of this disease. OBJECTIVES To explore the role of miR-145-5p in psoriasis. METHODS miRNA microarray analysis was performed in four patients with psoriasis and four controls. Quantitative reverse-transcriptase polymerase chain reaction and fluorescence in situ hybridization were used to identify the dysregulated miRNAs. Luciferase assays were performed to determine whether miR-145-5p targets mixed-lineage kinase (MLK)3. CCK-8 assay and Magnetic Luminex Assay were performed to measure cell proliferation and chemokine secretion. Western blot analysis was used to investigate the protein levels of MLK3 and its downstream effectors. Mouse models of psoriasis were established for in vivo experiments. RESULTS miR-145-5p was downregulated in psoriatic lesional skin. Luciferase assays showed that MLK3 is a direct target of miR-145-5p. Overexpression of miR-145-5p in normal human epidermal keratinocytes (NHEKs) suppressed cell proliferation and secretion of chemokines. In contrast, silencing miR-145-5p promoted NHEK proliferation and increased chemokine secretion. Silencing MLK3 abrogated miR-145-5p inhibitor-induced promotion of cell proliferation and chemokine expression. miR-145-5p regulates nuclear factor-κB and signal transducer and activator of transcription 3 by targeting MLK3. Delivery of agomiR-145-5p into the skin decreased epidermal hyperplasia and ameliorated psoriasis-like dermatitis. Delivery of antagomiR-145-5p led to the opposite effects. CONCLUSIONS Our findings indicate that miR-145-5p negatively regulates proliferation and chemokine secretion of NHEKs by targeting MLK3, and downregulation of miR-145-5p contributes to skin inflammation in psoriasis lesions.

Abstract
Hyperphosphorylation of Tau forming neurofibrillary tangles has been considered as a crucial event in the pathogenesis of Alzheimer's disease (AD). MiR-124-3p belongs to microRNA (miRNA) family and was markedly decreased in AD, however, the functions of miR-124-3p in the pathogenesis of AD remain unknown. We observed that the expression of miR-124-3p was significantly decreased in N2a/APP695swe cells; and transfection of miR-124-3p mimics not only attenuated cell apoptosis and abnormal hyperphosphorylation of Tau protein without any changes of total Tau protein, but also increased expression levels of Caveolin-1, phosphoinositide 3-kinase (PI3K), phospho-Akt (Akt-Ser473)/Akt, phospho-glycogen synthase kinase-3 beta (GSK-3β-Ser9)/GSK-3β in N2a/APP695swe cells. We further found that miR-12-3p directly targeted Caveolin-1; miR-124-3p inhibited abnormal hyperphosphorylation of Tau by regulating Caveolin-1-PI3K/Akt/GSK3β pathway in AD. This study reveals that miR-124-3p may play a neuroprotective role in AD, which may provide new ideas and therapeutic targets for AD.

Abstract
Objective: To compare and analyze the clinical outcomes of apically repositioned flap surgery and free gingival graft on keratinized gingival augmentation. Methods: Totally 30 partially edentulous patients treated with submerged implant surgery in mandibular molar area were recruited and divided into three groups: group 1(mean age: 41 years) and group 2 (mean age: 25 years) received free gingival graft 1 month after submerged implant surgery and second stage implant surgery3 months after submerged implant surgery; group 3(mean age: 44 years) received apically repositioned flap and second stage implant surgery 3 months after submerged implant surgery. The widths of keratinized gingiva were measured respectively at the time before the apically repositioned flap surgery/free gingival graft and 1 month, 6 months after the surgery. The thickness of keratinized gingiva was measured during the operation. Results: The widths of peri-implant keratinized gingiva of group 1 and group 2 were (3.1±1.2) mm and (3.5±1.0) mm 1 month after the free gingival graft surgery, (3.0±1.3) mm and (3.5±1.0) mm 6 months after the free gingival graft surgery, respectively. The widths of peri-implant keratinized gingiva in group 1 and group 2 demonstrated no statistically significant differences(P>0.05). The widths of peri-implant keratinized gingiva of group 3 was (2.6±0.5) mm 1 month after the apically repositioned flap surgery, (1.9±0.3) mm 6 months after the apically repositioned flap surgery, respectively. The widths of peri-implant keratinized gingiva(1 month and 6 months after the apically repositioned flap surgery) in group 3 showed statistically significant differences when compared with group 1 and group 2(P=0.008, P=0.000). Conclusions: The implant area treated with free gingival graft or apically repositioned flap exhibited increased width of the keratinized gingiva. The implants treated with free gingival graft exhibited more increased width of the keratinized gingiva compared with those treated with apically repositioned flap. Age showed little impact on keratinized gingival augmentation.

Abstract
Treatment of ducks congenitally infected with the duck hepatitis B virus (DHBV) using the guanosine analogue ganciclovir resulted in prompt and profound inhibition of viral DNA replication in serum and liver. By the end of the treatment period all the replicative intermediates, except the supercoiled DNA form, could not be detected. Within 2 weeks of cessation of treatment viral replication returned and, in some cases, rebound occurred. Sequential treatment with prednisolone followed by ganciclovir also resulted in inhibition of viral replication and, even though relapse was observed after therapy was discontinued, the rebound phenomenon was reduced. Ganciclovir significantly and selectively inhibited DHBV DNA replication but may be more efficacious if used in combination with compounds targeted to the viral supercoiled DNA form.

Abstract
Angiogenesis and lymphangiogenesis are thought to play a role in the pathogenesis of inflammatory bowel diseases (IBD). However, it is not understood if inflammatory lymphangiogenesis is a pathological consequence or a productive attempt to resolve the inflammation. This study investigated the effect of lymphangiogenesis on intestinal inflammation by overexpressing a lymphangiogenesis factor, vascular endothelial growth factor-C (VEGF-C), in a mouse model of acute colitis. Forty eight-week-old female C57BL/6 mice were treated with recombinant adenovirus overexpressing VEGF-C or with recombinant VEGF-C156S protein. Acute colitis was then established by exposing the mice to 5% dextran sodium sulfate (DSS) for 7 days. Mice were evaluated for disease activity index (DAI), colonic inflammatory changes, colon edema, microvessel density, lymphatic vessel density (LVD), and VEGFR-3mRNA expression in colon tissue. When acute colitis was induced in mice overexpressing VEGF-C, there was a significant increase in colonic epithelial damage, inflammatory edema, microvessel density, and neutrophil infiltration compared to control mice. These mice also exhibited increased lymphatic vessel density (73.0±3.9 vs 38.2±1.9, P<0.001) and lymphatic vessel size (1974.6±104.3 vs 1639.0±91.5, P<0.001) compared to control mice. Additionally, the expression of VEGFR-3 mRNA was significantly upregulated in VEGF-C156S mice compared to DSS-treated mice after induction of colitis (42.0±1.4 vs 3.5±0.4, P<0.001). Stimulation of lymphangiogenesis by VEGF-C during acute colitis promoted inflammatory lymphangiogenesis in the colon and aggravated intestinal inflammation. Inflammatory lymphangiogenesis may have pleiotropic effects at different stages of IBD.

Abstract
OBJECTIVE To explore the clinical characteristics of IgA nephropathy (IgAN) with severe chronic periodontitis and aggressive periodontitis. METHODS A total of 436 hospitalized patients who underwent renal needle biopsy in the department of nephrology of China-Japan Friendship Hospital from November 2013 to December 2014 were recruited in the study and blindly had periodontal examination. The patients were divided into IgAN group and non-IgAN group according to the renal pathology. The patients with IgAN were further categorized as non-periodontitis, chronic periodontitis and aggressive peridontitis group by Haas classification. The chronic periodontitis group was continually divided into mild, moderate and severe periodontitis group. The levels of interleukin (IL)-1β and IL-6 in gingival crevicular fluid were analyzed by enzyme-linked immunosorbent assays. RESULTS The prevalence of periodontitis in the study was 88.3% (385/436). The prevalence of chronic periodontitis and aggressive periodontitis were higher in patients with IgAN than those with non-IgAN (P<0.05). Degree of chronic periodontitis was correlated with pathologic grading of IgAN (r=0.48, P<0.001). Compared with IgAN patients with other types of periodontitis, those with severe chronic and aggressive periodontitis had more severe pathology, more frequent recurrent gross hematuria, higher levels of 24 h proteinuria, serum triglyceride and uric acid, higher periodontal probing depth and clinical attatchment level, as well as higer levels of IL-1β and IL-6, but had lower creatinine clearance rate (all P<0.05). CONCLUSIONS The prevalence of severe chronic and aggressive periodontitis was higher in patients with IgAN. Chronic periodontitis is correlated with the onset and development of IgAN. Patients with IgAN have worse condition with the aggravation of periodontitis.

Abstract
The intestinal epithelium is very peculiar for its continuous cell renewal, fuelled by multipotent stem cells localized within the crypts of Lieberkühn. Several lines of evidence have established the evolutionary conserved RNA-binding protein Musashi1 as a marker of adult stem cells, including those of the intestinal epithelium, and revealed its roles in stem cell self-renewal and cell fate determination. Previous studies from our laboratories have shown that Musashi1 controls stem cell-like features in medulloblastoma, glioblastoma, and breast cancer cells, and has pro-proliferative and pro-tumorigenic properties in intestinal epithelial progenitor cells in vitro. To undertake a detailed study of Musashi1's function in the intestinal epithelium in vivo, we have generated a mouse model, referred to as v-Msi, overexpressing Musashi1 specifically in the entire intestinal epithelium. Compared with wild type litters, v-Msi1 mice exhibited increased intestinal crypt size accompanied by enhanced proliferation. Comparative transcriptomics by RNA-seq revealed Musashi1's association with gut stem cell signature, cell cycle, DNA replication, and drug metabolism. Finally, we identified and validated three novel mRNA targets that are stabilized by Musashi1, Ccnd1 (Cyclin D1), Cdk6, and Sox4. In conclusion, the targeted expression of Musashi1 in the intestinal epithelium in vivo increases the cell proliferation rate and strongly suggests its action on stem cells activity. This is due to the modulation of a complex network of gene functions and pathways including drug metabolism, cell cycle, and DNA synthesis and repair.

Abstract
AIMS Reactive oxygen species (ROS)-mediated formation of mixed disulfides between critical cysteine residues in proteins and glutathione, a process referred to as protein S-glutathionylation, can lead to loss of enzymatic activity and protein degradation. Since mitochondria are a major source of ROS and a number of their proteins are susceptible to protein-S-glutathionylation, we examined if overexpression of mitochondrial thioltranferase glutaredoxin 2a (Grx2a) in macrophages of dyslipidemic atherosclerosis-prone mice would prevent mitochondrial dysfunction and protect against atherosclerotic lesion formation. METHODS AND RESULTS We generated transgenic Grx2aMac(LDLR-/-) mice, which overexpress Grx2a as an EGFP fusion protein under the control of the macrophage-specific CD68 promoter. Transgenic mice and wild type siblings were fed a high fat diet for 14 weeks at which time we assessed mitochondrial bioenergetic function in peritoneal macrophages and atherosclerotic lesion formation. Flow cytometry and Western blot analysis demonstrated transgene expression in blood monocytes and peritoneal macrophages isolated from Grx2aMac(LDLR-/-) mice, and fluorescence confocal microscopy studies confirmed that Grx2a expression was restricted to the mitochondria of monocytic cells. Live-cell bioenergetic measurements revealed impaired mitochondrial ATP turnover in macrophages isolated from Grx2aMac(LDLR-/-) mice compared to macrophages isolated from non-transgenic mice. However, despite impaired mitochondrial function in macrophages of Grx2aMac(LDLR-/-) mice, we observed no significant difference in the severity of atherosclerosis between wildtype and Grx2aMac(LDLR-/-) mice. CONCLUSION Our findings suggest that increasing Grx2a activity in macrophage mitochondria disrupts mitochondrial respiration and ATP production, but without affecting the proatherogenic potential of macrophages. Our data suggest that macrophages are resistant against moderate mitochondrial dysfunction and rely on alternative pathways for ATP synthesis to support the energetic requirements.

Abstract
Different pig breeds have shown differential susceptibility to the pathogen infection; however, molecular mechanisms of the infection susceptibility are not fully understood. Streptococcus suis type 2 (SS2) is an important zoonotic pathogen. To identify the genes responsible for infection susceptibility, pigs from two different breeds (Enshi black and Landrace) were inoculated with SS2 and their spleen transcriptome profiles were investigated in the present study. The differentially expressed genes (DEGs) were analyzed from infected versus control pigs in each breed, and then compared between both pig breeds. Enshi black pig showed more DEGs than Landrace (830 vs. 611) and most of these were due to down-regulated genes (543 vs. 387). However some DEGs were uniquely expressed in one breed, some were expressed in opposite direction in both breeds. A number of candidate genes and pathways are identified which might be involved in susceptibility to SS2, for example, MMP9 and Resistin were only significantly expressed in Landrace. NPG3 and PMAP23 were up-regulated in Landrace whereas down-regulated in Enshi black. LENG8 in control Landrace have inherently higher expression than control Enshi black. IGKV6 is down-regulated in Landrace but up-regulated in Enshi black. Overall, the transcriptome profiles are consistent with the clinical signs, i.e. the Enshi black is more susceptible to SS2 infection than Landrace. This is the first study to identify differential gene expression between indigenous and modern commercial pigs after in vivo SS2 infection using RNA-seq. The significant DEGs in splenic profiles between two pig breeds suggested considerable involvement of genetic background in susceptibility to the SS2 infection in pigs.

Abstract
The present study was undertaken to investigate the effects of maternal lead (Pb) exposure on the expression of interleukin (IL) 1β, IL 6, and glial fibrillary acidic protein (GFAP) in hippocampus of mice offspring. Pb exposure initiated from the beginning of gestation to weaning. Lead acetate (PbAc) administered in drinking solutions was dissolved in distilled deionized water at the concentrations of 0.1, 0.5 and 1% groups ,respectively. On the postnatal day 21, the Pb levels in their blood and hippocampus were determined by graphite furnace atomic absorption spectrometry. The expression of IL 1β, IL 6, and GFAP in hippocampus was measured by immunohistochemistry and Western blotting. The Pb levels in blood and hippocampus of all Pb-exposed groups were significantly higher than that of the control group ( p < 0.05). The expression of IL-1β, IL-6, and GFAP was increased in Pb-exposed groups in comparison with the control group ( p < 0.05). The high expression of IL-1β, IL-6, and GFAP in the hippocampus of pups may contribute to the neurotoxicity associated with maternal Pb exposure.

Abstract
OBJECTIVE Vegetarians are more vascular-healthy but those with subnormal vitamin B-12 status have impaired arterial endothelial function and increased intima-media thickness. We aimed to study the impact of vitamin B-12 supplementation on these markers, in the vegetarians. DESIGN Double-blind, placebo controlled, randomised crossover study. SETTING Community dwelling vegetarians. PARTICIPANTS Fifty healthy vegetarians (vegetarian diet for at least 6 years) were recruited. INTERVENTION Vitamin B-12 (500 µg/day) or identical placebo were given for 12 weeks with 10 weeks of placebo-washout before crossover (n=43), and then open label vitamin B-12 for additional 24 weeks (n=41). MEASUREMENT Flow-mediated dilation of brachial artery (FMD) and intima-media thickness (IMT) of carotid artery were measured by ultrasound. RESULTS The mean age of the subjects was 45±9 years and 22 (44%) were male. Thirty-five subjects (70%) had serum B-12 levels <150 pmol/l. Vitamin B-12 supplementation significantly increased serum vitamin B-12 levels (p<0.0001) and lowered plasma homocysteine (p<0.05). After vitamin B-12 supplementation but not placebo, significant improvement of brachial FMD (6.3±1.8% to 6.9±1.9%; p<0.0001) and in carotid IMT (0.69±0.09 mm to 0.67±0.09 mm, p<0.05) were found, with further improvement in FMD (to 7.4±1.7%; p<0.0001) and IMT (to 0.65±0.09 mm; p<0.001) after 24 weeks open label vitamin B-12. There were no significant changes in blood pressures or lipid profiles. On multivariate analysis, changes in B-12 (β=0.25; p=0.02) but not homocysteine were related to changes in FMD, (R=0.32; F value=3.19; p=0.028). CONCLUSIONS Vitamin B-12 supplementation improved arterial function in vegetarians with subnormal vitamin B-12 levels, proposing a novel strategy for atherosclerosis prevention.

Abstract
Pharmacokinetic (PK) studies were conducted to determine the potential PK interactions when spinosad and milbemycin oxime (MBO) are administered simultaneously. Investigations used commercial MBO tablets (C-MBO; Interceptor(®) Flavor Tabs, active ingredient MBO, Novartis Animal Health, Greensboro, NC, USA), novel-source (Elanco) MBO (E-MBO) in a gelatin capsule, spinosad API (Active Pharmaceutical Ingredient using registered manufacturing process) in a gelatin capsule, spinosad tablets (Comfortis(®) chewable beef flavored tablets, active ingredient spinosad, Elanco Animal Health, Greenfield, IN, USA), and the recently registered spinosad + E-MBO combination tablets (Trifexis™ chewable beef flavored tablets, active ingredients E-MBO and spinosad, Elanco Animal Health, Greenfield, IN, USA). Regardless of the source of MBO, in the presence of spinosad, greater systemic exposure of MBO was obtained as compared to MBO administered alone. Target animal safety studies conducted with dose multiples of spinosad and MBO indicate the increased exposure of MBO does not have implications on adverse clinical reactions. Further research is required to determine whether the higher levels of MBO have any implications for improved effectiveness as compared to C-MBO. Effectiveness studies conducted with 0.5 mg/kg of E-MBO in combination tablets demonstrated noninterference against C-MBO with both products achieving >99% effectiveness against the dose-limiting nematode, Ancylostoma caninum. No statistical differences were detected in the PK of MBO when comparing animals receiving E-MBO (without spinosad) and C-MBO. Also, the PK of spinosad was unaltered when co-administered with MBO.
