Abstract
ABSTRACT Ketosis can seriously impair cow performance. This study detected changes in prepartum blood metabolic parameters for predicting postpartum ketosis occurrence in dairy cows. Body condition score (BCS) was assessed before and after delivery. Blood samples of 63 cows were collected from 10 days before calving to 10 days after calving to measure metabolic parameters including β-hydroxybutyric acid (BHBA), non-esterified fatty acid (NEFA), glucose (GLU), total bilirubin (TBIL), direct bilirubin (DBIL), indirect bilirubin (IBIL), total protein (TP), albumin (ALB), globulin (GLO), alanine aminotransferase (ALT), and aspartate aminotransferase (AST). There was a postpartum subclinical ketosis incidence of 42.25%. Compared with prepartum, plasma, levels of BHBA, AST, and NEFA significantly increased postpartum, and prepartum AST (R=0.57) and NEFA (R=0.45) showed a significant positive correlation with ketosis postpartum. Plasma GLU level significantly decreased postpartum and was significantly negatively correlated with ketosis (R=-0.21). Receiver operating characteristic curve analysis revealed prepartum BSC < 2.88, and prepartum plasma AST > 68.0 U/L, GLU < 3.97mmol/L, NEFA > 0.27mmol/L, and BHBA > 0.43mmol/L, indicating a high risk of subclinical ketosis postpartum. These levels can be used as risk indicators to predict the occurrence of subclinical ketosis in postpartum cows.

Abstract
Furans represent one of the most important classes of intermediates in the conversion of non-edible lignocellulosic biomass into bio-based chemicals and fuels. At present, bio-furan derivatives are generally obtained from cellulose and hemicellulose fractions of biomass via the acid-catalyzed dehydration of their relative C6-C5 sugars and then converted into a wide range of products. Furfural (FUR) and 5-hydroxymethylfurfural (HMF) are surely the most used furan-based feedstocks since their chemical structure allows the preparation of various high-value-added chemicals. Among several well-established catalytic approaches, hydrogenation and oxygenation processes have been efficiently adopted for upgrading furans; however, harsh reaction conditions are generally required. In this review, we aim to discuss the conversion of biomass derived FUR and HMF through unconventional (transfer hydrogenation, photocatalytic and electrocatalytic) catalytic processes promoted by heterogeneous catalytic systems. The reaction conditions adopted, the chemical nature and the physico-chemical properties of the most employed heterogeneous systems in enhancing the catalytic activity and in driving the selectivity to desired products are presented and compared. At the same time, the latest results in the production of FUR and HMF through novel environmental friendly processes starting from lignocellulose as well as from wastes and by-products obtained in the processing of biomass are also overviewed.

Abstract
ABSTRACT The objective of this study was to investigate the influence of plasma pathological changes before timed artificial insemination (TAI) on pregnancy of cows. The contents of estrogen (E2), progesterone (P4), glucose (Glu), selenium (Se), brain-derived neurotrophic factor (BDNF), and histamine (HIS) in plasma of 48 Holstein cows were measured before TAI. According to the estrus detection, the cows were divided into estrus (E) and anestrus (A) groups. After pregnancy testing at 28 d after TAI, two groups of E and A were divided into positive pregnancy of E group (EP+), negative pregnancy of E group (EP-), positive pregnancy of A group (AP+), and negative pregnancy of A group (AP-). The contents of E2, P4, Glu, Se, BDNF and hIS significantly differed among the four groups (P<0.01). The ROC analysis was used to determine the risk of negative pregnancy test (-) after TAI was increased when plasma E2 was less than 46.45 pmol/L in cows before TAI. The changes in E2, P4,hIS, Glu, and BDNF in the blood of natural estrus and natural anestrus cows affected the pregnancy after TAI. the level of E2 in plasma may be used to assess the risk of negative pregnancy after TAI.

Abstract
Base excision repair (BER) acts upon the most important mechanism of the DNA repair system, protecting DNA stability and integrity from the mutagenic and cytotoxic effects. Multiple researches have indicated that single-nucleotide polymorphisms (SNPs) in the BER-related gene may be associated with the susceptibility of ovarian cancer. However, the results are controversial. In this two-center case-control study, 19 potentially functional SNPs in six BER-related genes (hOGG1, APE1, PARP1, FEN1, LIG3 and XRCC1) was genotyped in 196 ovarian cancer cases and 272 cancer-free controls. And, their associations with ovarian cancer risk were assessed by unconditional logistic regression analyses. We found that PARP1 rs8679 and hOGG1 rs293795 polymorphisms were associated with a decreased risk of ovarian cancer under dominant model (adjusted OR=0.39, 95% CI=0.17-0.90, P=0.026; and adjusted OR=0.36, 95% CI=0.13-0.99, P=0.049, respectively). Stratification analysis demonstrated that this association was more pronounced in the subgroups of lower BMI and patients with early menarche and serous carcinoma. Moreover, LIG3 rs4796030 AA/AC variant genotypes performed an increased risk of ovarian cancer under recessive model (adjusted OR=1.54, 95% CI=1.01-2.35, P=0.046), especially in the subgroups of higher BMI, early clinic stage and the carcinoma at the left. These results suggested that PARP1, hOGG1 and LIG3 polymorphisms might impact on the risk of ovarian cancer. However, more researches with larger and different ethnic populations are warranted to support our findings.

Abstract
To assess the correlation between thyroid function and glucolipid metabolism in type 1 diabetic adults. A retrospective analysis was conducted in 230 type 1 diabetic adults who were hospitalized in the Department of Endocrinology of Shandong Provincial Hospital Affiliated to Shandong University from January 2008 to January 2020. It showed that thyroid stimulating hormone(TSH) was significantly positively correlated with total cholesterol (TC) (r=0.239), triglycerides (TG) (r=0.166) and low-density lipoprotein cholesterol (LDL-C) (r=0.249), respectively (all P<0.05). Free triiodothyronine (FT3) was significantly negatively correlated with fasting plasma glucose (FPG) (r=-0.272), glycated hemoglobin (HbA1c) (r=-0.240), TC (r=-0.197) and LDL-C (r=-0.220), respectively (all P<0.05). Free thyroxine (FT4) was negatively correlated with TC (r=-0.171) and LDL-C (r=-0.170), respectively (all P<0.05). TC was an independent predictor of TSH, FT3 and FT4, FT3 and FT4 were independent predictors of HbA1c. TSH was an independent predictor of TC, TG and LDL-C. Thyroid function is closely related to glucolipid metabolism in type 1 diabetic adults.

Abstract
Reverse transcription, an essential event in the HIV-1 life cycle, requires deoxynucleotide triphosphates (dNTPs) to fuel DNA synthesis, thus requiring penetration of dNTPs into the viral capsid. The central cavity of the capsid protein (CA) hexamer reveals itself as a plausible channel that allows the passage of dNTPs into assembled capsids. Nevertheless, the molecular mechanism of nucleotide import into the capsid remains unknown. Employing all-atom molecular dynamics (MD) simulations, we established that cooperative binding between nucleotides inside a CA hexamer cavity results in energetically favorable conditions for passive translocation of dNTPs into the HIV-1 capsid. Furthermore, binding of the host cell metabolite inositol hexakisphosphate (IP6) enhances dNTP import, while binding of synthesized molecules like benzenehexacarboxylic acid (BHC) inhibits it. The enhancing effect on reverse transcription by IP6 and the consequences of interactions between CA and nucleotides were corroborated using atomic force microscopy, transmission electron microscopy, and virological assays. Collectively, our results provide an atomistic description of the permeability of the HIV-1 capsid to small molecules and reveal a novel mechanism for the involvement of metabolites in HIV-1 capsid stabilization, nucleotide import, and reverse transcription. This study shows that the HIV-1 capsid protein, in addition to its structural role, regulates reverse transcription, an essential metabolic process of the virus, by mediating the import of nucleotides. In addition, host cell metabolites such as inositol phosphates are recruited by the capsid to regulate viral DNA synthesis.

Abstract
This study aims to evaluated the prognostic and predictive roles of DNA mismatch repair status in colon cancer patients treated with oxaliplatin-based chemotherapy. From 2005 to 2008, patients who underwent curative surgical resection for high-risk stage II or stage III colon cancer were recruited in this study. These patients had been received oxaliplatin-based chemotherapy. A total 324 patients were included (41.7% at stage II and 58.3% at stage III), and 59 patients (18.2%) exhibited mismatch repair-deficient (dMMR). The prognostic analysis revealed an increase in disease-free survival (DFS) for dMMR patients versus proficient MMR (pMMR) patients (81.4% versus 64.2%, P = 0.009), and overall survival (OS) (86.4% versus 69.1%, P = 0.004). Among the 82 patients who did not receive adjuvant therapy, the 5-year DFS was significantly higher in patients with dMMR (81.3%) than in patients with pMMR (49.7%, P = 0.040). In the multivariate models, dMMR was independently associated with improved DFS (HR = 2.171, 95% CI: 1.108 - 4.253, P = 0.024) and OS (HR = 2.521, 95% CI: 1.190 - 5.339, P = 0.016). In the predictive analysis, it was observed that the benefit of treatment significantly differed according to the DNA MMR status (P = 0.020). Compared with surgery alone, oxaliplatin-based adjuvant chemotherapy improved the 5-year DFS (69.9% versus 56.2%, P = 0.024) among patients with pMMR in the multivariable analysis (HR = 0.794, 95% CI = 0.646 - 0.976, P = 0.029). In contrast, the oxaliplatin-based chemotherapy in the group with dMMR had no benefit in DFS (83.1% versus 81.8%, HR 1.040, 95% CI: 0.276 - 3.922, P = 0.954). Patients with dMMR colon cancer are associated with improved survival rates, compared with pMMR colon cancer. MMR status is an independent prognostic biomarker for DFS in patients with high-risk stage II and stage III colon cancer. Oxaliplatin-based adjuvant chemotherapy mainly benefits patients with pMMR, but may not benefit patients with tumors exhibiting dMMR.

Abstract
BACKGROUND Subsequent to the implementation of the universal salt iodisation policy, China has all but eliminated the iodine deficiency disorders. However, pregnant women are still experiencing mild iodine deficiency. The present study explored factors that could relate to mild iodine deficiency in pregnant women. METHODS In total, 2400 pregnant women were enrolled using a multistage, stratified, random sampling method in Shanghai. Data were collected via a standardised questionnaire. The urine samples and household cooking salt samples were collected for the detection of urinary iodine and salt iodine concentrations. RESULTS The median urinary iodine concentration (MUIC) was 148.0 μg L-1 for all participants, and 155.0 μg L-1 , 151.0 μg L-1 and 139.6 μg L-1 in the first, second and third trimesters. The MUIC in the third trimester was significantly lower than that of the first trimester (P < 0.05). The usage rates of iodised salt and qualified-iodised salt were 71.5% and 59.4%, respectively. Iodine-related knowledge score composition ratio was significantly different between the high and low UIC groups (P < 0.05). Participants' MUIC increased significantly with the increases in iodine-related knowledge score (P < 0.001). The third trimester was a significant risk factor for high UIC, whereas high iodine-related knowledge score, actively learning dietary knowledge and having a habit of consuming iodine-rich food were significant protective factors for high UIC (P < 0.05). CONCLUSIONS Iodine level is adequate among pregnant women in Shanghai during the first and the second trimesters, although it is is insufficient in the third trimester. Good iodine-related knowledge, attitudes and behaviours are important for pregnant women with respect to maintaining adequate urinary iodine.

Abstract
OBJECTIVE MicroRNAs have been implicated to play a crucial regulating role in human cancers. The study aims to explore the role and clinical significance of miR-497 in pancreatic ductal adenocarcinoma (PDAC). PATIENTS AND METHODS The relative expression of miR-497 in human PDAC tissue samples and adjacent normal tissues was measured using the quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). Cell Counting Kit (CCK-8) assay, cell migration, and invasion assays were performed to detect cell proliferation and invasion ability. Downstream target gene was confirmed by using luciferase activity assays. QRT-PCR and Western blotting assays also were performed. RESULTS We found that miR-497 expression was significantly downregulated in PDAC tissues and cells. Lower miR-497 expression associated with lymph node metastasis and predicts a poor prognosis in PDAC patients. In in vitro assay, we demonstrated that miR-497 overexpression inhibited cell proliferation, migration, and invasion of PDAC. Furthermore, we demonstrated that HMGA2 was a direct target of miR-497 in PDAC cells. MiR-497 inhibited cell proliferation and invasion by regulating HMGA2 expression. CONCLUSIONS Our results indicated that miR-497 may serve as a predictor for PDAC and could be a novel target of PDAC treatment.

Abstract
INTRODUCTION AND OBJECTIVES Allergen-specific immunotherapy (ASIT) is the only allergic disease-modifying therapy available for children and adults, and recombinant allergens are an interesting approach to improve allergy diagnosis and ASIT. Tyrophagus putrescentiae is a common storage mite that produces potent allergens. The aim of this study was to express and characterize recombinant group 4 allergen protein of T. putrescentiae (Tyr p 4), and to further investigate allergenicity and potential epitopes of Tyr p 4. MATERIALS AND METHODS The cDNA encoding Tyr p 4 was generated by RT-PCR and subcloned into pET-28a(+) plasmid. The plasmid was then transformed into E. coli cells for expression. After purification by nickel affinity chromatography and identification by SDS-PAGE, recombinant Tyr p 4 protein was used for a skin prick test and an ELISA to determine the allergic response. RESULTS Study participants' allergic response rate to Tyr p 4 protein was 13.3% (16/120). Eight B-cell epitopes and three T-cell epitopes of Tyr p 4 were predicted. CONCLUSIONS Similar to group 4 allergens of other species of mite, allergenicity of Tyr p 4 is weak. The expression, characterization and epitope prediction of recombinant Tyr p 4 protein provide a foundation for further study of this allergen in the diagnosis and ASIT of storage mite allergy.

Abstract
Peripartal cows mobilize not only body fat but also body protein to satisfy their energy requirements. The objective of this study was to determine the effect of prepartum BCS on blood biomarkers related to energy and nitrogen metabolism, and mRNA and protein abundance associated with AA metabolism and insulin signaling in subcutaneous adipose tissue (SAT) in peripartal cows. Twenty-two multiparous Holstein cows were retrospectively classified into a high BCS (HBCS; n = 11, BCS ≥ 3.5) or normal BCS (NBCS; n = 11, BCS ≤ 3.17) group at d 28 before expected parturition. Cows were fed the same diet as a total mixed ration before parturition and were fed the same lactation diet postpartum. Blood samples collected at -10, 7, 15, and 30 d relative to parturition were used for analyses of biomarkers associated with energy and nitrogen metabolism. Biopsies of SAT harvested at -15, 7, and 30 d relative to parturition were used for mRNA (real time-PCR) and protein abundance (Western blotting) assays. Data were subjected to ANOVA using the MIXED procedure of SAS (v. 9.4; SAS Institute Inc., Cary, NC), with P ≤ 0.05 being the threshold for significance. Cows in HBCS had greater overall plasma nonesterified fatty acid concentrations, due to marked increases at 7 and 15 d postpartum. This response was similar (BCS × Day effect) to protein abundance of phosphorylated (p) protein kinase B (p-AKT), the insulin-induced glucose transporter (SLC2A4), and the sodium-coupled neutral AA transporter (SLC38A1). Abundance of these proteins was lower at -15 d compared with NBCS cows, and either increased (SLC2A4, SLC38A1) or did not change (p-AKT) at 7 d postpartum in HBCS. Unlike protein abundance, however, overall mRNA abundances of the high-affinity cationic (SLC7A1), proton-coupled (SLC36A1), and sodium-coupled amino acid transporters (SLC38A2) were greater in HBCS than NBCS cows, due to upregulation in the postpartum phase. Those responses were similar to protein abundance of p-mTOR, which increased (BCS × Day effect) at 7 d in HBCS compared with NBCS cows. mRNA abundance of argininosuccinate lyase (ASL) and arginase 1 (ARG1) also was greater overall in HBCS cows. Together, these responses suggested impaired insulin signaling, coupled with greater postpartum AA transport rate and urea cycle activity in SAT of HBCS cows. An in vitro study using adipocyte and macrophage cocultures stimulated with various concentrations of fatty acids could provide some insights into the role of immune cells in modulating adipose tissue immunometabolic status, including insulin resistance and AA metabolism.
