Abstract
Reducing dietary protein has been of interest to the global poultry industry to improve bird health, welfare, and industry sustainability. Low protein (LP) diets are typically glycine (Gly) deficient and produce poor performance. Supplementing the diet with Gly or precursors of Gly can overcome this deficiency. A feeding experiment was conducted with 330 Ross 308 off-sex males across 5 treatments in a randomized design using 11 birds per pen replicated 6 times. Grower and finisher treatments were fed from day 7 to 21 and day 21 to 35, respectively. The objective was to test the efficacy of supplementation with Gly and Gly equivalents (Glyequiv), serine (Ser) and threonine (Thr), in plant-based LP diets on bird performance against a standard protein (SP) diet containing meat and bone meal. Glycine, Ser, or Thr were supplemented on Glyequiv basis to an approximately 3% lower CP diet to achieve the same digestible Gly and Ser level as the SP diet. Nitrogen efficiency, serum uric acid, blood plasma amino acids (AA) and AA digestibility were also investigated to monitor potential metabolic effects. Birds fed the LP diet were only 3.3% lower in final body weight than the SP treatment (2,556 vs. 2,641 g) while the supplementation of Gly or Ser had no effect. Supplementation of Thr reduced final body weight by 9.5% (P < 0.05). Reducing CP increased N efficiency by 9.6% (P < 0.05) and decreased blood serum uric acid by 26.9% (P < 0.001) in the finisher treatments. Glycine and Ser supplementation in LP diets had no effect on these parameters. The LP diet reduced AA digestibility and blood plasma AA while the supplementation with either Gly, Ser, or Thr increased overall AA digestibility (P < 0.05) but had no overall effect on blood plasma AA. Further research is required into Gly metabolism; however, Thr supplementation depressed growth and therefore is not feasible to cover Gly deficiency in LP diets on a Glyequiv basis.

Abstract
CD28H and B7-H5 have been identified as receptor-ligand pairs in the B7/CD28 family, and have co-stimulatory activity in immune cells. Here, we have systematically reviewed the research reports concerning the CD28H/B7-H5 pathway. It was found that CD28H is mainly expressed in T cells and natural killer (NK) cells with naive and poorly differentiated properties, and repeated antigen stimulation leads to permanent loss of CD28H. In tumors, CD28H is mainly expressed in tissue-resident memory (TRM ) lymphocyte T cells, which is associated with improved tumor prognosis. B7-H5 is a ligand for CD28H and is widely expressed in tumor cells. B7-H5 expression is closely related to the prognosis of the tumor. Studies have shown that high expression of B7-H5 in tumor is related to a worse prognosis for lung cancer, osteosarcoma, oral squamous cell carcinoma (OSCC), breast carcinoma, human clear cell renal cell carcinoma (ccRCC), intrahepatic cholangiocarcinoma (ICC), bladder urothelial carcinoma (BUC) and colorectal cancer (CRC), but is associated with a better prognosis for pancreatic ductal adenocarcinoma (PDAC) and glioma. Controversial views exist in studies on gastric cancer prognosis.

Abstract
Objective: To investigate the safety and feasibility of longitudinal transpancreatic U-sutures invaginated pancreatojejunostomy (Chen's pancreaticojejunostomy technique) in laparoscopic pancreaticoduodenectomy (LPD). Methods: Clinical data of 116 consecutive patients who underwent LPD using Chen's pancreaticojejunostomy technique in Hunan Provincial People's Hospital from May 2017 to December 2018 were retrospectively analyzed. Among these patients, 66 were males and 50 were females. The median age was 58 years old (32-84 yeas old). All 116 patients underwent pure laparoscopic whipple procedure with Child reconstruction method, using Chen's pancreaticojejunostomy technique. The intraoperative and postoperative data of patients were analyzed. Results: All 116 patients underwent LPD successfully. The mean operative time was (260.3±33.5) minutes (200-620 minutes). The mean time of pancreaticojejunostomy was (18.2±7.6) minutes (14-35 minutes). The mean time of hepaticojejunostomy was (14.6±6.3) minutes (10-25 minutes). The mean time of gastrojejunostomy was (12.0±5.5) minutes (8-20 minutes). The mean estimated blood loss was (106.0±87.6) ml (20-800 ml). Postoperative complications were: 11.2%(13/116) of cases had postoperative pancreatic fistula (POPF), including 10.3% (12/116) of biochemical fistula and 0.9%(1/116) of grade B POPF, no grade C POPF occurred; 10.3%(12/116) had gastrojejunal anastomotic bleeding; 3.4%(4/116) had hepaticojejunal anastomotic fistula; 3.4%(4/116) had delayed gastric emptying; 4.3% (5/116) had localized abdominal infection; 12.1%(14/116) had pulmonary infection; postoperative mortality were 0(0/116) and 1.7%(2/116) within 30 days and 90 days, respectively. One patient died of massive abdominal bleeding secondary to Gastroduodenal artery pseudoaneurysm rupture, the other patient died of extensive tumor recurrence and metastasis after surgery. Conclusions: Chen's pancreaticojejunostomy technique is safe and feasible for LPD.It is an option especially for surgeons who have not completed the learning curve of LPD.

Abstract
Streptococcus mutans is a major cariogenic pathogen that resides in multispecies oral microbial biofilms. The VicRK 2-component system is crucial for bacterial adaptation, virulence, and biofilm organization and contains a global and vital response regulator, VicR. Notably, we identified an antisense vicR RNA (AS vicR) associated with an adjacent RNase III–encoding ( rnc) gene that was relevant to microRNA-size small RNAs (msRNAs). Here, we report that ASvicR overexpression significantly impeded bacterial growth, biofilm exopolysaccharide synthesis, and cariogenicity in vivo. Transcriptome analysis revealed that the AS vicR RNA mainly regulated carbohydrate metabolism. In particular, overproducing AS vicR demonstrated a reduction in galactose and glucose metabolism by monosaccharide composition analysis. The results of high-performance gel permeation chromatography revealed that the water-insoluble glucans isolated from AS vicR presented much lower molecular weights. Furthermore, direct evidence showed that total RNAs were disrupted by rnc-encoded RNase III. With the coexpression of T4 RNA ligase, putative msRNA1657, which is an rnc-related messenger RNA, was verified to bind to the 5′-UTR regions of the vicR gene. Furthermore, AS vicR regulation revealed a sponge regulatory-mediated network for msRNA associated with adjacent RNase III–encoding genes. There was an increase in AS vicR transcript levels in clinical S. mutans strains from caries-free children, while the expression of AS vicR was decreased in early childhood caries patients; this outcome may be explored as a potential strategy contributing to the management of dental caries. Taken together, our findings suggest an important role of AS vicR-mediated sponge regulation in S. mutans, indicating the characterization of lactose metabolism by a vital response regulator in cariogenicity. These findings have a number of implications and have reshaped our understanding of bacterial gene regulation from its transcriptional conception to the key roles of regulatory RNAs.

Abstract
Band inversions are key to stabilising a variety of novel electronic states in solids, from topological surface states to the formation of symmetry-protected three-dimensional Dirac and Weyl points and nodal-line semimetals. Here, we create a band inversion not of bulk states, but rather between manifolds of surface states. We realise this by aliovalent substitution of Nb for Zr and Sb for S in the ZrSiS family of nonsymmorphic semimetals. Using angle-resolved photoemission and density-functional theory, we show how two pairs of surface states, known from ZrSiS, are driven to intersect each other near the Fermi level in NbGeSb, and to develop pronounced spin splittings. We demonstrate how mirror symmetry leads to protected crossing points in the resulting spin-orbital entangled surface band structure, thereby stabilising surface state analogues of three-dimensional Weyl points. More generally, our observations suggest new opportunities for engineering topologically and symmetry-protected states via band inversions of surface states.

Abstract
BACKGROUND A high sodium intake is associated with obesity and metabolic syndrome. However, little is known regarding whether greater salt intake is a potential risk factor for non-alcoholic fatty liver disease (NAFLD). We thus prospectively investigated whether individuals with higher perceived dietary salt intake had a higher risk of developing NAFLD. METHODS The present study included 35 023 participants (22 629 men and 12 394 women) from the Kailuan study who were free of NAFLD at baseline (2006) and who did not drink alcohol at baseline and during follow-up (2006-2014; follow-rate 95.2%). NAFLD was defined as a participant who had been diagnosed with fatty liver at least twice by ultrasound tests conducted every 2 years during follow-up. Dietary salt intake was determined by a self-report question and was classified into three categories: low (<6 g day-1 ), medium (6-9 g day-1 ) or high (≥10 g day-1 ). Cox proportional models were used to estimate the risk of NAFLD, adjusting for potential confounders, such as age, sex, education, physical activity, smoking, income, occupation, marriage, body mass index, waist circumference and blood pressure, as well as serum concentrations of glutamic-pyruvic transaminase, glucose, total cholesterol and triglyceride. RESULTS During 8 years of follow-up, we identified 5102 incident NAFLD cases. After adjusting for potential confounders, the hazard ratio (95% conference interval) for NAFLD was 1.12 (1.00, 1.26) for medium salt intake and 1.19 (1.02,1.39) for high salt consumption (P trend = 0.03) relative to the low salt consumption group. CONCLUSIONS A perceived high salt intake was associated with a higher future risk of NAFLD.

Abstract
1. The aim of this study was to examine the effect of yeast cell wall (YCW) on performance and physiological responses of broiler chickens under subclinical necrotic enteritis challenge.2. Six treatments in a 2 × 3 factorial arrangement (non-challenged or challenged plus no supplement, YCW or antibiotics (AB)) was used. Each treatment was replicated eight times with 12 birds per replicate. The treatments included: (1) Positive control (PC; no additive, not challenged); (2) Negative control (NC; no additive, with challenge); (3) YCWN = yeast cell wall (2.0 g/kg diet, not challenged; (4) YCWC = yeast cell wall (2.0 g/kg diet, challenged); (5) ABN = zinc bacitracin 50 ppm + Salinomycin 60 ppm, not challenged); (6) ABC = zinc bacitracin 50 ppm + Salinomycin 60 ppm, challenged).3. Eimeria challenge at 9 d of age did not affect feed intake (FI), body weight gain (BWG), FCR or liveability at 10 d. The BWG and FCR at 10 d were greater (P < 0.05) in birds fed YCW or AB (AB) diets relative to the PC or NC groups. On 24 and 35 d, FI, BWG, FCR and flock uniformity (28 d) were greater (P < 0.05) in the challenged groups fed YCW or AB diets compared to NC group.4. Supplementation with YCW ameliorated the negative effects of NE on liver, spleen and bursa weight of birds.5. Necrotic enteritis challenge decreased (P < 0.05) caecal Lactobacillus and Bifidobacterium spp. counts, and increased ileum lesion score and caecal Clostridium perfirngens counts. This was reversed by the addition of either YCW or AB.6. Supplementation with YCW and AB resulted to a greater (P < 0.05) dressing percentage and meat yield (35 d).7. The results indicated that YCW plays a vital role in improving the physiological response and performance of broiler chickens under subclinical necrotic enteritis challenge.

Abstract
Abstract
Background
Metabolic syndrome (MetS) is now a common public health problem. Few researches have reported the relationship between MetS and the risk of renal cell cancer (RCC). To investigate the association of metabolic syndrome and its components with the risk of RCC in Chinese males, the study was performed in the Kailuan male cohort, a large prospective cohort study.
Methods
A total of 104,333 eligible males enrolled in the every 2-year health checkup were involved in the Kailuan male cohort study (2006-2015). Information on demographic and socioeconomic characteristics, lifestyle, medical history and laboratory tests at baseline entry was obtained. Univariable and multivariable Cox proportional hazards regression models were used to estimate the association between MetS and the RCC risk.
Results
During a median follow-up of 8.9 years, 131 RCC cases were verified over a total of 824,211.96 person-years. Among the 5 single MetS components, hypertension (Systolic/diastolic blood pressure≥130/85 mm Hg or antihypertensive drug treatment of previously hypertension) (HR = 2.35, 95%CI:1.48-3.72) and elevated triglyceride (TG) (≥1.7mmol/L) (HR = 1.78, 95%CI:1.23-2.56) showed significant risk for RCC. Multivariate analysis showed that compared to those who did not meet MetS diagnostic criteria (number of abnormal MetS components<3), HR of RCC risk for participants with MetS was 1.95 (95% CI 1.35-2.83). The number of abnormal MetS components was linearly associated with an increased risk of RCC (P trend<0.001), and the HRs of RCC risk for males with 1, 2 and ≥3 MetS components were 1.27 (0.56-2.90), 2.42 (1.12-5.20) and 3.32 (1.56-7.07), respectively, compared with subjects without MetS components.
Conclusions
MetS was inversely associated with of RCC risk in males.
Key messages
MetS might be one of the scientific and important predictors of RCC. Controlling metabolic syndrome may potentially have key scientific and clinical significance for RCC prevention.

Abstract
The annual bluegrass weevil Listronotus maculicollis requires chilling exposure to terminate reproductive diapause during overwintering, but the effects of temperature on its post-diapause development in spring remain unclear. To explore this effect, overwintering adults were transferred from cold conditions (6°C/4°C, L:D 10:14) to different warm-up temperatures at L:D 12:12. When weevils were transferred to 7, 14 and 21°C in December and late January, the sizes of male and female reproductive organs were significantly smaller at 7°C than at 14 and 21°C. When weevils were transferred to 7, 9, 11, 13 and 15°C in late January, higher temperatures facilitated the post-diapause development. In both sexes, the sizes of reproductive organs and developmental rate increased with temperature. Reproductive organs did not grow significantly at 7°C in males and at 7-9°C in females, at which the percentage of developing weevils remained low. The time required for 50% of individuals to resume development was 44, 18, 13 and 8 days at 9, 11, 13 and 15°C, respectively, in males and 19, 14 and 8 days at 11, 13 and 15°C, respectively, in females. The threshold temperature for post-diapause development was 7.8°C in males, based on which 61.7 degree-days coincided with 50% of individuals developing. Under field conditions, the percentage of male and female maturity and insemination rate were low until early March, but all reached 100% by late March.

Abstract
RESUMO O presente artigo é um relato sobre uma fêmea de D. novemcinctus que foi capturada de forma imprevista, durante um projeto de avaliação sanitária de animais silvestres sinantrópicos do município de Toledo/PR (autorização Sisbio/Ibama n. 55109-1). Durante a avaliação física, amostras de fezes foram coletadas após defecação espontânea e encaminhadas para análise. O material foi submetido aos métodos de flutuação simples em solução hipersaturada de cloreto de sódio e centrífugo-flutuação em sacarose. Na leitura das lâminas obtidas pelo método de centrífugo-flutuação em sacarose, foram observadas estruturas com comprimento de aproximadamente 10µm, forma bicônica e um tampão em cada extremidade, compatíveis com esporocistos de Monocystis sp. Protozoários do filo Apicomplexa, os Monocystis sp., são geralmente parasitas de anelídeos, como as minhocas. Esse organismo é comumente correlato a pseudoparasitismo em vários animais, porém não foram encontrados relatos de pseudoparasitismo desse agente em tatus-galinhas, logo essa é a primeira descrição de Monocystis sp. em espécime de D. novemcinctus.

Abstract
BACKGROUND Endothelial dysfunction plays a key role in diabetic atherosclerosis. High glucose (HG) is considered a stimulator in the development of diabetic atherosclerosis. The endoplasmic reticulum (ER) stress response is involved in HG-induced vascular injury. Crocin has antioxidative and antiapoptotic properties. OBJECTIVE The current study was to evaluate whether crocin can protect human umbilical vein endothelial cells (HUVECs) from HG-induced injury and explored the associated mechanism. METHODS HUVECs were treated with 33 mmol/L glucose as the HG condition. The endothelial protective effects of crocin were evaluated by comparison with the control groups. RESULTS The exposure of HUVECs to HG for 24 h remarkably induced the ER stress response and a sequence of injuries, as demonstrated an increase in the apoptotic cell number, the reactive oxygen species level and inflammatory cytokine generation, as well as a decline in vascular endothelial growth factor A expression. These changes were markedly alleviated by pretreating the HUVECs with either crocin or 4-phenylbutyrate (ER stress inhibitor) before exposure to HG. CONCLUSION Crocin exerted antioxidative, antiapoptotic, anti-inflammatory and proangiogenic effects in the HG-induced HUVEC injury model, which were probably mediated by a favorable modification of ER stress that requires further investigation.

Abstract
The oral cavity contains a distinct habitat that supports diverse bacterial flora. Recent observations have provided additional evidence that sRNAs are key regulators of bacterial physiology and pathogenesis. These sRNAs have been divided into 5 functional groups: cis-encoded RNAs, trans-encoded RNAs, RNA regulators of protein activity, bacterial CRISPR (clustered regularly interspaced short palindromic repeat) RNAs, and a novel category of miRNA-size small RNAs (msRNAs). In this review, we discuss a critical group of key commensal and opportunistic oral pathogens. In general, supragingival bacterial sRNAs function synergistically to fine-tune the regulation of cellular processes and stress responses in adaptation to environmental changes. Particularly in the cariogenic bacteria Streptococcus mutans, both the antisense vicR RNA and msRNA1657 can impede the metabolism of bacterial exopolysaccharides, prevent biofilm formation, and suppress its cariogenicity. In Enterococcus faecalis, selected sRNAs control the expression of proteins involved in diverse cellular processes and stress responses. In subgingival plaques, sRNAs from periodontal pathogens can function as novel bacterial signaling molecules that mediate bacterial-human interactions in periodontal homeostasis. In Porphyromonas gingivalis, the expression profiles of putative sRNA101 and sRNA42 were found to respond to hemin availability after hemin starvation. Regarding Aggregatibacter actinomycetemcomitans (previously Actinobacillus actinomycetemcomitans), a major periodontal pathogen associated with aggressive periodontitis, the predicted sRNAs interact with several virulence genes, including those encoding leukotoxin and cytolethal distending toxin. Furthermore, in clinical isolates, these associated RNAs could be explored not only as potential biomarkers for oral disease monitoring but also as alternative types of regulators for drug design. Thus, this emerging subspecialty of bacterial regulatory RNAs could reshape our understanding of bacterial gene regulation from their key roles of endogenous regulatory RNAs to their activities in pathologic processes.

Abstract
Abstract
Background: The conventional way of patient treatment should be following guidelines. While in clinical practice, patients received treatments very often away from suggested guideline. In this report, we reviewed glioma patients received real world treatment at Sun Yat-sen University Cancer Center (SYSUCC) and results of this patient series.
Methods: Total of 1215 glioma patients received surgery at SYSUCC from 2000 to 2017 were enclosed for analysis. The pathologic diagnosis of patients has followed WHO classification (initially 2007 standard, than 2016 standard).
Results: A total of 1001 newly diagnosed brain glioma patients were analyzed, including 90 cases WHO grade I, 307 grade II, 239 grade III and 365 grade IV. The median age of onset was 14 (1–75), 35 (2–69), 41 (8–82) and 50 (2–86) years old, respectively, for grade I, II, III and IV glioma patients. Tumor total resection was achieved in 567 patients (57.5%). Among all patients, 331 high-grade gliomas (54.8%) and 159 low-grade glioma (40.1%) received radiotherapy, whereas 285 high-grade gliomas (47.1%) and 80 low-grade tumors (20.2%) received chemotherapy. Among high-grade gliomas, the median OS of glioblastoma, anaplastic astrocytoma and anaplastic oligodendroglial tumors were 17.7 months (15.7–19.7 months), 33.7 months (24.0–43.4 months) and 110.6 months (43.5–177.7 months), respectively, whereas the median OS of low-grade gliomas was not reach. The 5-year survival rate of grade I, II, III and IV gliomas was 94.7%, 73.7%, 45.1% and 18.6%, respectively. Multivariate analysis identified that onset age, Karnofsky performance status, tumor location, preoperative seizure, pathological subtype, resection extent and post-surgical treatment were independent predictors of OS for patients with high-grade gliomas. Patients received post-surgical radiotherapy and (or) chemotherapy had better survival than those without adjuvant treatment (grade III: 53.3 vs. 20.6 months, p =0.012; grade IV: 22.9 vs. 12.3 months, p < 0.001). For low-grade gliomas, patients’ age, Ki-67 index, tumor subtype and resection extent were associated with clinical outcomes.
Conclusions: Glioma patients received treatments do not always following guidelines in clinical practice. Although standard care for patients may beneficial for prognosis, personalized treatment may more acceptable for patients and even resulting better outcome which should keep in mind in routine clinical practice.
