Published: December 2021

Abstract
Pseudorabies virus (PRV) is a pathogen of swine resulting in devastating disease. Some viral infections can cause endoplasmic reticulum (ER) stress and unfolded protein response (UPR) to restore ER homeostasis. However, the mechanism of how PRV induces ER stress and UPR activation remains unclear. Here, levels of proteins or transcriptional factors of three UPR pathways were examined in suspension-cultured BHK-21 cells to investigate PRV-induced ER stress. Results showed that PRV triggered ER stress and UPR of the host cells with the upregulated expression of glucose-related protein 78 kD and 94 kD (GRP78 and GRP94). The protein kinase RNA-like ER kinase (PERK) pathway was activated to upregulate ATF4, CHOP, and GADD34 expression. Additionally, the inositol requiring kinase 1 (IRE1) pathway was triggered by splicing of X box-binding protein 1 (XBP1) mRNA and the enhanced expression of p58IPK and EDEM1. Furthermore, our data demonstrated that PRV took advantage of ER stress to accelerate its replication with the activation of the PERK and IRE1 pathways in suspension-cultured BHK-21 cells, and the glycoprotein B played a crucial role in ER stress.

Abstract
Mycobacterium bovis, a member of the Mycobacterium tuberculosis complex (MTBC), is the causative agent of bovine TB (bTB) in animals. Spread occurs through inhalation or ingestion of bacilli transmitted from infected individuals. Early and accurate detection of infected African buffaloes shedding M. bovis is essential for interrupting transmission. In this study, we determined if M. bovis shedding could be detected in buffalo oronasal secretions using a molecular transport media (PrimeStore MTM) with oronasal swabs and a rapid qPCR assay (Xpert MTB/RIF Ultra). Bovine TB test-positive buffaloes were culled, then tissue samples and oronasal swabs collected post-mortem for mycobacterial culture and Ultra testing, respectively. The Ultra detected MTBC DNA in 5/12 swabs from M. bovis culture-confirmed buffaloes. Oronasal swabs from M. bovis negative buffaloes (n = 20) were negative on Ultra, indicating the high specificity of this test. This study showed that MTM can successfully preserve MTBC DNA in oronasal swabs. The proportion of MTBC positive oronasal swabs was higher than expected and suggests that the Ultra may be a sensitive method for identifying infected buffaloes. Further studies are needed to confirm the utility of the Ultra assay with oronasal swabs as a promising assay to evaluate MTBC shedding in buffaloes.

Abstract
Background: Benign prostatic hyperplasia is the most common urological condition affecting quality of life in men. Its incidence increases proportionally with age and typically manifests with mixed lower urinary tract symptoms. Giant prostatic hyperplasia, the most extreme form of BPH, can present with more serious clinical consequences and presents a challenge to surgical management. Case presentation: We present the first reported case of provoked deep vein thrombosis and near fatal pulmonary embolus from a symptomatic megaprostate exerting pelvic mass effect on the external iliac vein, further complicated by haematuria post catheter-directed thrombolysis. Conclusion: This case highlights the success of prostate artery embolization and catheter-directed thrombolysis to treat potential sequelae of giant prostate hyperplasia.

Published: December 2021

Abstract
Background: The herbal-pair, Kansui and Licorice, belongs to the "eighteen incompatible medicaments" category of traditional Chinese medicine. Kansuiphorin C (KC) is the main toxic component of Kansui. The main component of licorice is glycyrrhizic acid, which is hydrolyzed to glycyrrhetinic acid. Currently, the synergistic mechanism between Kansui and Licorice is unclear. Methods: Rat liver microsomes were used in this experiment, HPLC was used to detect the contents of KC, glycyrrhizic acid, and glycyrrhetinic acid to determine whether these compounds are metabolic substrates of CYP450. A control group with isozyme inhibitors was also employed to reveal the isozyme subtypes involved in compound metabolism. To further explain the induction or inhibitory effect of the above compounds on liver microsomal enzymes, enzyme activity was indirectly revealed based on changes in the contents of known metabolites of CYP2E1, CYP2C9, and CYP3A4. Results: KC and glycyrrhetinic acid were metabolic substrates of CYP450. CYP2E1 and CYP2C9 are mainly involved in the partial metabolism of glycyrrhizic acid in the liver. CYP2E1 and CYP3A4 are mainly involved in the partial metabolism of glycyrrhetinic acid in the liver. CYP2E1, CYP2C9, and CYP3A4 did not play a major role in the metabolism of KC. KC had little effect on the metabolism of glycyrrhizic acid and glycyrrhetinic acid. Glycyrrhizic acid, glycyrrhetinic acid, and KC induced CYP3A4 and inhibit CYP2E1. Both glycyrrhizic acid and glycyrrhetinic acid could inhibit the induction of CYP3A4 after combination with KC. KC with glycyrrhizic acid could synergistically inhibit the activity of CYP2E1, while KC with glycyrrhetinic acid could synergistically induce the activity of CYP2E1 Conclusion: KC and glycyrrhetinic acid were metabolic substrates of CYP450. KC, glycyrrhizic acid and glycyrrhetinic acid have different inducing and inhibiting effects on CYP450 enzyme.

Published: December 2021

Abstract
Background: As consumption of commercial complementary food (CCF) during infancy and toddlerhood is common, the aim of the present study was to describe the current (2020) German market of CCF products with a special focus on ingredients, macronutrients, and the practice of nutrient fortification.Methods: Information on age declarations, ingredients, energy and nutrient contents, and nutrient fortification of 1057 CCF products was obtained by contacting the producers and searching manufacturers' websites. Each product was assigned to one of thirteen product categories (menus, milk-cereal-meal, fruit-cereal-meal, oil, vegetables, meat, fish, fruits, cereals, snack foods, pouches, desserts, beverages) and stratified into infants’ CCF (< 12 months, n=829) and toddlers’ CCF (> 12 months, n=228). Descriptive statistics were used in order to give an overview of the available products.Results: Highest protein content (% of energy content, %E) was found in meat products. More than 50 %E of total sugar was found in pouches, beverages, cereal fruit meals, and fruits. Highest median salt content was found in toddlers’ menus and desserts. Around one third of infants’ CCF products and one quarter of toddlers’ products were fortified with nutrients. Vitamin B1 (thiamin) was the most frequently fortified nutrient, followed by vitamin C, iron, calcium, and vitamin D. Apple was the type of fruit listed most often in products with fruits, whereas carrot was the most frequent vegetable among CCF with vegetables. Conclusion: The available product categories as well as the high sugar content of most CCFs currently available on the German market may promote unhealthy dietary habits. Parents need to be educated about the optimal selection of products.

Abstract
Introduction: Infective endocarditis (IE) is endothelial damage of the endocardium, which is caused by infection. The etiologic agents' highest mortality and morbidity rates are associated with staphylococcus aureus (S. aureus). Accordingly, the knowledge of different risk factors for IE caused by the S. aureus is necessary.Material and methods: This study is an observational-analytical retrospective cohort study on 139 patients with staphylococcus aureus bacteremia (SAB), who referred to a cardiac center during 2011-2019. This study aimed to evaluate the risk factors in 48 patients with staphylococcus aureus endocarditis, who were selected from139 patients with S. aureus bacteremia. Results: The mean age (±SD) of the patients is 56.61 (±16.58), and85 (61.2%) persons are male. Forty-eight patients (34.5%) are diagnosed with staphylococcus aureus endocarditis regarding Duke criteria. In this study, the following risk factors were significantly associated with S. aureus endocarditis: age (p=0.003), long-term bacteremia (p=0.041), prosthetic heart valve (p=0.016), pre-existing IE (p=0.048), and embolic events (p=0.039).Conclusion: According to the findings, a significant number of patients with staphylococcus aureus bacteremia (SAB) have IE with different risk factors. Future studies with a larger sample size are recommended to detect IE risk factors.

Published: December 2021

Abstract
Science is based on evidence that can be measured or observed through methodical techniques which are expressed in several ways, either quantitatively or qualitatively. The technical photograph becomes one of the most important key tools to the result’s disclosure. In the microbiological research, several pieces of evidence can be indicated with variables that are deeply related to the means of culture; pH and color variation, halo formation, overlay of structures, culture shape, among others. The employment of technical photographs, as a strategy of the experimental observation and reliable representation, is indispensable. The protocol presented here suggests the production of the photographic support in microbiological tests runs on Petri dishes, taken by a smartphone to obtain high-quality images, besides showing tools to edit images through PowerPoint. The support is composed of a paper tube with a transparent border, whose reduced light penetration avoids problems, such as the luminous reflection over the Petri dishes or the environment itself. The edition consists of the photograph variation, and in clipping and pasting on uniform backgrounds to provide further detailing. The protocol allowed a standardized photograph collection in high quality, which is ideal for a comparative portrait of microbiological behaviors. The image editing enabled a framework and greater visibility of physical and biological structures in the exhibition of photographs inside the manuscript, such as the removal of noises, background alterations, deformities or irregularities. This protocol is a tool that helps the researcher on the knowledge-obtaining process, and it is applied to different experiments or adapted into the most variable research subjects.

Abstract
Orthohantaviruses are transmitted to humans mostly through small mammals that are the reservoirs of these viruses. Because orthohantaviruses show high genetic variability through geographic regions, the genetic characterization of these viruses with whole genome sequencing is of great importance to clarify the molecular epidemiology and track their genetic changes in the reservoir hosts. We have previously reported the presence of Dobrava-Belgrade orthohantavirus (DOBV) in the Igneada region, Kirklareli province by showing antibodies against the virus in rodents and by sequencing partial genomes of the virus. Here we report the whole genome sequencing of DOBV Igneada strain directly from Apodemus flavicollis’ lung tissue by next-generation sequencing followed by phylogenetic analyses. In addition, viral protein structures of DOBV Igneada strain were modelled, and in silico prediction analyses of amino acid changes on viral protein function and stability were performed.The phylogenetic analysis showed a close relation between the DOBV Igneada strain from Turkey and DOBV Ano-Poroia strain from Greece. Similarity plot analysis revealed also similarities between DOBV Igneada strain and other DOBV strains from the Balkans such as Greece, Croatia, and Slovenia. Additionally, in silico prediction suggested that G318E, Y322H, and S324P mutations on Gn glycoprotein are deleterious, and all amino acid changes decrease the stability of both Gn and Gc glycoproteins.In conclusion, full orthohantaviral genomes can be obtained directly from rodent lung tissues allowing detailed genetic and structural analyses of orthohantaviruses. The DOBV Igneada strain shows great similarity to the prototype Ano-Poroia strain, yet it was predicted that DOBV Igneada strain may have some changes on its pathogenicity and its structure warranting further research.

Abstract
Phenylalanine hydroxylase deficiency (PAHD) is the most prevalent inborn error of amino acid metabolism in China, has a complex phenotype with many variants and genotypes among different populations. Here, we analyzed the phenylalanine hydroxylase（ PAH ） gene mutations in a cohort of 93 PAHD patients from Fujian Province. And, the analysis of genotype and phenotype correlation in patients with PAHD was also determined. 44 different pathogenic variants were identified, including five novel variants. The three most prevalent mutations among all patents were p.Arg53His (18.03%), p.Arg241Cys (14.75%), and p.Arg243Gln (7.65%). The frequency of the p.Arg53His variant was the highest in patients with mild hyperphenylalaninemia (MHP), while the frequency of the p.Val399= and p.Arg111Ter variants was the highest in patients with classic phenylketonuria(cPKU). The most abundant genotypes observed in PAHD patients were p.Arg53His/p.Arg243Gln, p.Arg53His/p.IVS4-1G>A, and p.Arg53His/p.Arg241Cysp. As for the genotype-phenotype prediction, the APV/GPV system performed well in predicting the actual phenotype, as the overall consistency rate was 85.71% for PAHD patients. In conclusion, we established a PAH gene mutation spectrum in the PAHD patients in Southeastern China. A quantitative correlation analysis between genotype and phenotype severity is helpful for genetic counseling and management.

Abstract
Background

Currently, the role of serum-based biomarkers such as microRNAs in cancer diagnosis has been extensively established. This study aimed to determine expression levels of bioinformatically selected miRNAs and whether they can be used as biomarkers or a new therapeutic target in patients with Acute Lymphoblastic Leukemia (ALL).
Materials and Methods

The expression levels of serum miR-22, miR-122, miR-217, and miR-367 in 21 ALL patients and 21 healthy controls were measured using quantitative real-time PCR. The receiver operating characteristic (ROC) curve and the associated area under the curve (AUC) was used to assess candidate miRNAs' diagnostic value as a biomarker.
Results

The results showed that miR-217 was markedly decreased in patients with ALL compared to controls. Moreover, miR-22, miR-122, and miR-367 were found to be upregulated. Furthermore, ROC analysis showed that serum miR-217 and miR-367 could differentiate ALL patients from the healthy individuals, while miR-22 has approximate discriminatory power that requires further investigation.
Conclusion

Collectively, the results suggested that miR-217 may play a tumor suppressor role in ALL, whereas miR-22, miR-122, and miR-367 could function as an oncogene. Overall, miR-22, miR-217, and miR-367 could be considered possible biomarkers for the early diagnosis of ALL.
Pyruvate Kinase M1 Regulates Butyrate Metabolism in Cancerous Colonocytes

Published: December 2021

Abstract
Colorectal cancer (CRC) cells shift metabolism toward aerobic glycolysis and away from using oxidative substrates such as butyrate. Pyruvate kinase M1/2 (PKM) is an enzyme that catalyzes the last step in glycolysis, which converts phosphoenolpyruvate to pyruvate. M1 and M2 are alternatively spliced isoforms of the Pkm gene. The PKM1 isoform promotes oxidative metabolism, whereas PKM2 enhances aerobic glycolysis. We hypothesize that the PKM isoforms are involved in the shift away from butyrate oxidation towards glycolysis in CRC cells. Here, we find that PKM2 is increased and PKM1 is decreased in human colorectal carcinomas as compared to non-cancerous tissue. To test whether PKM1/2 alter colonocyte metabolism, we created a knockdown of PKM2 and PKM1 in CRC cells to analyze how butyrate oxidation and glycolysis would be impacted. We report that butyrate oxidation in CRC cells is regulated by PKM1 levels, not PKM2. Decreased butyrate oxidation observed through knockdown of PKM1 and PKM2 is rescued through re-addition of PKM1. Diminished PKM1 lowered mitochondrial basal respiration and decreased mitochondrial spare capacity. We demonstrate that PKM1 suppresses glycolysis and inhibits hypoxia-inducible factor-1 alpha. These data suggest that reduced PKM1 is, in part, responsible for increased glycolysis and diminished butyrate oxidation in CRC cells.

Abstract
Hospital-based transmission played a dominant role in MERS-CoV and SARS-CoV epidemics but large-scale studies of its role in the SARS-CoV-2 pandemic are lacking. Such transmission risks spreading the virus to the most vulnerable individuals and can have wider-scale impacts through hospital-community interactions. Using data from acute hospitals in England we quantify within-hospital transmission, evaluate likely pathways of spread and factors associated with heightened transmission risk, and explore the wider dynamical consequences. We show that hospital transmission is likely to have been a major contributor to the burden of COVID-19 in England. We estimate that between June 2020 and March 2021 between 95,000 and 167,000 patients acquired SARS-CoV-2 in hospitals with nosocomially-infected patients likely to have been the main sources of transmission to other patients. Increased transmission to patients was associated with hospitals having fewer single rooms and lower heated volume per bed. Moreover, we show that reducing hospital transmission could substantially enhance the efficiency of punctuated lockdown measures in suppressing community transmission. These findings reveal the previously unrecognised scale of hospital transmission, have direct implications for targeting of hospital control measures, and highlight the need to design hospitals better-equipped to limit the transmission of future high consequence pathogens.

Abstract
Background insulin receptor substrate-1 (IRS-1) rs956115 is associated with vascular risk in patients with coronary artery disease (CAD) and concomitant diabetes. CYP2C19 rs4244285 modulates clopidogrel responsiveness and predicts outcome of CAD. We designed this study to explore the association between IRS-1 rs956115, CYP2C19 rs4244285, and platelet reactivity as well as 1-year outcome in patients with CAD undergoing percutaneous coronary intervention (PCI).Methods IRS-1 rs956115, CYP2C19 rs4244285 genotypes and platelet reactivity were assessed in 1611 post-PCI patients. Major adverse cardiovascular events (MACE) which were defined as a composite of cardiovascular death, myocardial infarction and ischemic stroke over 1-year were evaluated. One-way ANOVA was used to compare the platelet reactivity among different genotypes of rs956115 and rs4244285. Multivariable Cox proportional hazard model analysis was used to estimate the association between genotypes of rs956115 and rs4244285 and risk of MACE.Results At 1 month, patients with rs956115 CG genotype had significantly lower level of residual ADP-induced platelet aggregation (PLADP) than those with CC genotype. PLADP significantly increased with the number of rs4244285 A alleles. Patients with rs956115 CG or GG genotype had a 2.09-fold higher risk of MACE than those with CC genotype (adjusted HR=2.09; 95%CI:1.04-4.19; P=0.0376), and those with rs4244285 GA genotype had a 2.19-fold higher risk than GG homozygotes (adjusted HR=2.19; 95%CI:1.13-4.24; P=0.0200). There was no significant difference in risk between AA and GG homozygotes. No interaction between rs956115 and rs4244285 was observed. Conclusions In post-PCI patients, rs956115 GG/CG and rs4244285 GA genotypes were associated with 2.09- and 2.19-fold cardiovascular risks respectively at 1-year follow-up. The effect of rs956115 appeared to be independent of known clinical predictors, while that of rs4244285 GA could be mediated by lower clopidogrel response.
