Expression and Variations in EPO Associated with Oxygen Metabolism in Tibetan Sheep

Simple Summary The hypoxa-related gene EPO is a key factor in erythropoiesis. In high-altitude indigenous species, the expression of and variations in the EPO gene are closely related to changes of altitude (oxygen concentration). In this study, the mRNA expression levels of gene EPO in different tissues and organs of Hu sheep (100 m) and Tibetan sheep at different altitudes (2500 m, 3500 m, 4500 m) were detected by RT-qPCR, and Kompetitive Allele-Specific PCR (KASP) was used to study the effects of EPO variation on plateau hypoxia adaptation in Tibetan sheep. The results suggest that variations in the EPO gene were correlated with some blood gas indexes of Tibetan sheep, and the expression of the EPO gene was related to changes in altitude. Abstract After a long period of adaptive evolution, Tibetan sheep have adapted to the plateau environment in terms of genetics, physiology and biochemistry, but the mechanism of hypoxia adaptation has not been fully elucidated, and the functional genes and molecular mechanisms regulating the hypoxia adaptation of Tibetan sheep need to be further studied. In this study, Tibetan sheep were selected as the research object, and the mRNA expression levels of the hypoxa-related gene EPO in heart, lung, kidney, liver, spleen and longissimus dorsi muscle of Hu sheep (100 m) and Tibetan sheep at different altitudes (2500 m, 3500 m, 4500 m) were assessed by RT-qPCR. The SNPs loci were detected by sequencing and Kompetitive Allele-Specific PCR (KASP) technology, then the correlation between genetic polymorphism and blood gas was analyzed. The results show that the expression of the EPO gene was the highest in the kidney, indicating that the expression of EPO gene had tissue differences. The expression levels of the EPO gene in the heart, lung and liver of Tibetan sheep at a 4500 m altitude were significantly higher than those in Hu sheep (p < 0.05), and the levels in the hearts of Tibetan sheep increased with the increase in altitude. Three mutations were identified in the EPO gene, the SNPs (g.855 A > C) in exon 1 and the SNPs (g.1985 T > G and g.2115 G > C) in exon 4, which were named EPO-SNP1, EPO-SNP2 and EPO-SNP3, respectively, and all three SNPs showed three genotypes. Correlation analysis showed that g.2115 G > C sites were significantly correlated with pO2 (p < 0.05), and haplotype combinations were significantly correlated with pO2 (p < 0.05). Thesee results suggest that the expression of the EPO gene is altitude-differentiated and organ-differentiated, and the EPO gene variants have significant effects on pO2, which may be beneficial to the adaptation of Tibetan sheep to hypoxia stress.
Inducing Melanoma Cell Apoptosis by ERp57/PDIA3 Antibody in the Presence of CPI-613 and Hydroxychloroquine

The combination of the cancer mitochondrial metabolic inhibitor CPI-613 and hydroxychloroquine has tumor-suppressive effects on clear cell sarcoma, which shares pathobiological properties with melanoma. Therefore, we intended to examine the effects of a combination of CPI-613 and hydroxychloroquine on the growth of melanoma cells in the present study. However, cell death was not induced in melanoma cells. Therefore, a monoclonal antibody, ICT, that induced apoptosis in melanoma cells in combination with CPI-613 and hydroxychloroquine was developed. Immunoprecipitation, mass spectrometry, and small interfering RNA (siRNA)-mediated gene silencing demonstrated that ICT targeted Endoplasmic Reticulum Resident Protein 57/ Protein Disulfide Isomerase Family A Member 3 (ERp57/PDIA3), which was first identified as being upregulated by metabolic depletion stress and is localized on the cell surface during immunogenic cell death. The combination of CPI-613 and hydroxychloroquine enhanced the localization of ERp57/PDIA3 to the surface of melanoma cells. siRNA-mediated downregulation of ERp57/PDIA3 did not significantly induce ICT-mediated apoptosis in melanoma cells in the presence of CPI-613 and hydroxychloroquine. Therefore, the ICT antibody acts as a tumor suppressor in melanoma cells by targeting the cell membrane ERp57/PDIA3, expression of which was enhanced by the combination of CPI-613 and hydroxychloroquine.
Optimizing Power Losses and Efficiency of Broadband Parallel-Circuit Class-E Power Amplifier

This paper presents a design method for a watt-level high-efficiency broadband power amplifier (BPA) with a generalized parallel-circuit (PC) Class-E model. A combination of the single-reactance compensation technique (S-RCT) and Chebyshev low-pass (LP) impedance matching network (MN) is used for achieving PA’s broadband characteristics. The analytical expression of the operation and power loss mechanisms of PC Class-E PA, which includes the effects of a finite DC-feed inductance, transistor on-resistance, and a broadband MN, is elaborated. As an example, a highly-efficient broadband PC (BPC) Class-E PA operating at 12 V drain supply voltage is implemented and verified experimentally. The designed PA exhibits high-efficiency characteristics of 82.15%-86.3% drain efficiency (DE) and 36.92-38.57 dBm output power ( $P_{out}$ ) with 19.95-23.11 dB power gain in the band from 7 MHz to 9.4 MHz. The measured results show good agreement with the theoretical and simulated results.
Woody plant species diversity in the last wild habitat of the Derby Eland (Taurotragus derbianus derbianus Gray, 1847) in Niokolo Koba National Park, Senegal, West Africa

The Niokolo Koba National Park (NKNP) in Senegal is the last refuge of the critically endangered antelope of the subspecies Derby Eland (Taurotragus derbianus derbianus Gray, 1847). Woody plants, that provide shelters and forage for the Eland in NKNP, were assessed for their floristic diversity to characterize its confined habitat. Hence, 156 square plots of 20m x 20m were established randomly in the confined area of the Derby Eland. In each plot, list of plants species, their number of individuals, and the environmental factors (soil hardness and type, altitude, percentages of vegetation cover and fire occurrence) were noted. Fifty (50) trees species belonging to 40 genera and 29 families were recorded. The most represented families were Combretaceae (13.92%), Leguminosae-mimosoideae (12.66 %), Leguminosae-caesalpinioideae (11.39 %), Leguminosae-papilionoideae (7.59 %), Rubiaceae (7.59 %) and Tiliaceae (6.33 %). The most abundant species were Combretum glutinosum Perr. ex DC. , (28.79%), Pterocarpus erinaceus Poir. (12.42%), Crossopteryx febrifuga (Afzel. ex G. Don) (7.30%), Strychnos spinosa Lam. (7.18%) and Hexalobus monopetalus (A. Rich.) Engl. & Diels (7.06 %). Altitude, fire occurrence and vegetation cover were the most important environmental factors influencing the distribution of plants species. Results suggest conservation defenders of Eland, for a sustainable management plan, to invest in in-situ fencing in order to increase possibilities of conservation of this critically endangered species in its native area. Key words: Plant inventory, specie composition, confined habitat, wild, sustainable management.
Multifunctionality Analysis of Structural Supercapacitors— A Review

Structural supercapacitors (SSCs) are multifunctional energy storage composites (MESCs) that combine the mechanical properties of fiber-reinforced polymers and the electrochemical performance of supercapacitors to reduce the overall mass in lightweight applications with electrical energy consumption. These novel MESCs have huge potentials, and their properties have improved dramatically since their introduction in the early 2000’s. However, the current properties of SSCs are not sufficient for complete energy supply of electrically driven devices. To overcome this drawback, the aim of the current study is to identify key areas for enhancement of the multifunctional performance of SSCs. Critical modification paths for the SSC constituents are systematically analyzed. Special focus is given to the improvement of carbon fiber-based electrodes, the selection of structural electrolytes and the implementation of separators for the development of more efficient SSCs. Finally, current SSCs are compared in terms of their multifunctionality including material combinations and modifications.
Study of Isocitrate Dehydrogenase 1and 2 Mutations in Adult Egyptian Patients with Denovo Acute Myeloblastic Leukemia, Their Relation to Clinical Characteristics, FLT3/ITD and Nucleophosmin 1 Mutations and Impact on Treatment Outcome

Background: Acute myeloid leukaemia (AML) is a malignancy that is heterogeneous in nature characterized by genetic abnormalities some of which are established in the diagnosis and prognosis of the disease. An additional role for alterations in epigenetic mechanisms has been also highlighted in the pathogenesis of the disease. This may have a role in determining the disease outcome, impact the treatment decision and provide options for targeted therapies especially in patients who lack genetic aberrations. One of the modes of epigenetic dysregulation is mutation in genes encoding isocitrate dehydrogenase 1 and 2 that has been observed in AML with a higher incidence in patients with normal karyotype (NK). Aim of the work: The aim of this work was to study the frequency of IDH1 (R132) and IDH2 (R140Q, R172K) mutations in adult Egyptian patients with de novo acute myeloblastic leukemia (AML), their relation with clinical characteristics, other molecular markers (the internal tandem duplication (ITD)) mutation of FLT3 gene and NPM1 gene mutation) and impact on treatment outcome. Methods: Peripheral blood samples from 50 adult patients with denovo acute myeloid leukemia, admitted to the haematology unit at Alexandria Main University Hospital from February 2015 to February 2017, were used. The polymerase chain reaction-restriction fragment length polymorphism method (PCR-RFLP) was used for detection of IDH1 codon R132 and IDH2 codons (R140, R172) mutations on genomic DNA. PCR was used for detection of FLT3-ITD mutation on genomic DNA. PCR was used for detection of NPM1 mutation on RNA. Results: IDH 1and 2 mutations occurred in 30% of newly diagnosed AML patients and 47.6% of NK patients. Both mutations did not co-occur except in one case. IDH positive patients were significantly older than IDH negative patients (p=0.003). There was no statistically significant correlation between any of the clinical parameters and the IDH mutations. FAB-M2 was the most common FAB subtype among IDH positive patients. No correlation between IDH mutations and NPM1 or FLT3 could be demonstrated. IDH positive patients had significantly lower CR rates after induction chemotherapy than IDH negative patients (p=0.021). Conclusion: IDH1, 2 mutations are recurring genetic alterations in AML with a higher incidence in patients with normal karyotype and they may have an unfavorable impact on clinical outcome in adult AML patients.

Promoting Pro-environmental Behaviors in a Zambian Context: The Effects of Place Attachment and Loyalty to a Natural Tourist Setting

Pro-environmental behaviors are fundamental given the human induced environmental problems the world faces today. This study offers an integrated approach to understanding an avenue for promoting pro-environmental behaviors through an investigation of the relationships among place attachment, destination loyalty and pro-environmental behaviors intentions using a Zambian context. A model is proposed in which the relationships among the three constructs are examined. Data for this study was collected from 1,060 Zambian domestic tourists at the Victoria Falls World Heritage site using on-site self administered surveys. Data was analyzed using structural equation modeling. Empirical results showed that place attachment had a significant effect on destination loyalty and a significant indirect effect on pro-environmental intentions. Destination loyalty had a direct effect on pro-environmental intentions. These findings suggest that promoting relational-oriented long-term relationships between tourists and natural tourist settings has potential to activate personal responsibility for the state of the environment.

The current state of phage therapy in livestock and companion
 animals

In a global context, bacterial diseases caused by pathogenic bacteria have inflicted sustained damage on both humans and animals. Although antibiotics initially appeared to offer an easy treatment for most bacterial infections, the recent rise of multidrug-resistant bacteria, stemming from antibiotic misuse, has prompted regulatory measures to control antibiotic usage. Consequently, various alternatives to antibiotics are being explored, with a particular focus on bacteriophage (phage) therapy for treating bacterial diseases in animals. Animals are broadly categorized into livestock, closely associated with human dietary habits, and companion animals, which have attracted increasing attention. This study highlights phage therapy cases targeting prominent bacterial strains in various animals. In recent years, research on bacteriophages has gained considerable attention, suggesting a promising avenue for developing alternative substances to antibiotics, particularly crucial for addressing challenging bacterial diseases in the future.
The Role of ATP and P2X Purinoceptor 7 in the Development of Cerebral Tau

ATP release and signalling via the P2X7 receptor have been implicated in numerous pathological processes including neurodegeneration and may play a role in the development of tauopathies. We injected ATP analogue bzATP intraventricularly into C57BL/6 mice, pre-treated with either intraperitoneal P2X7R antagonist Brilliant Blue G (BBG) or vehicle. Behavioural outcomes, levels of phosphorylated tau, and immunohistochemical changes in astrocytes and microglia were assessed at 2 weeks and 3 months after treatment. We observed increased immobile time in the tail suspension test and poor performance on rotarod for bzATP-treated mice at 3 months post-treatment, which were diminished by BBG pre-treatment. Western blot revealed increased levels of phosphorylated tau in bzATP-treated mice compared to controls. Astrocytic marker GFAP showed increased periventricular staining at both 2 weeks and 3 months for bzATP-treated mice but microglial marker IBA1 showed no changes. In summary, ATP-P2X7R-mediated mechanisms lead to development of behavioural deficits and increased
Pseudomonas chlororaphis IRHB3 assemblies beneficial microbes and activates JA-mediated resistance to promote nutrient utilization and inhibit pathogen attack

Introduction The rhizosphere microbiome is critical to plant health and resistance. PGPR are well known as plant-beneficial bacteria and generally regulate nutrient utilization as well as plant responses to environmental stimuli. In our previous work, one typical PGPR strain, Pseudomonas chlororaphis IRHB3, isolated from the soybean rhizosphere, had positive impacts on soil-borne disease suppression and growth promotion in the greenhouse, but its biocontrol mechanism and application in the field are not unclear. Methods In the current study, IRHB3 was introduced into field soil, and its effects on the local rhizosphere microbiome, disease resistance, and soybean growth were comprehensively analyzed through high-throughput sequencing and physiological and molecular methods. Results and discussion We found that IRHB3 significantly increased the richness of the bacterial community but not the structure of the soybean rhizosphere. Functional bacteria related to phosphorus solubilization and nitrogen fixation, such as Geobacter, Geomonas, Candidatus Solibacter, Occallatibacter, and Candidatus Koribacter, were recruited in rich abundance by IRHB3 to the soybean rhizosphere as compared to those without IRHB3. In addition, the IRHB3 supplement obviously maintained the homeostasis of the rhizosphere microbiome that was disturbed by F. oxysporum, resulting in a lower disease index of root rot when compared with F. oxysporum. Furthermore, JA-mediated induced resistance was rapidly activated by IRHB3 following PDF1.2 and LOX2 expression, and meanwhile, a set of nodulation genes, GmENOD40b, GmNIN-2b, and GmRIC1, were also considerably induced by IRHB3 to improve nitrogen fixation ability and promote soybean yield, even when plants were infected by F. oxysporum. Thus, IRHB3 tends to synergistically interact with local rhizosphere microbes to promote host growth and induce host resistance in the field.
Bone Marrow Adipose Tissue Is Not Required for Reconstitution of the Immune System following Irradiation in Male Mice

Bone marrow adipose tissue (BMAT) is hypothesized to serve as an expandable/contractible fat depot which functions, in part, to minimize energy requirements for sustaining optimal hematopoiesis. We investigated whether BMAT is required for immune reconstitution following injury. Male wild type (WBB6F1, WT) and BMAT-deficient WBB6F1/J-KitW/KitW-v/J (KitW/W-v) mice were lethally irradiated. Irradiation was followed by adoptive transfer of 1000 purified WT hematopoietic stem cells (HSCs). The extent of immune reconstitution in blood, bone marrow, and lymph nodes in the irradiated mice was determined using HSCs from green fluorescent protein (GFP)-expressing mice. We also evaluated skeletal response to treatment. Detection of GFP-positive B and T cells in peripheral blood at 4 and 9 weeks following adoptive transfer and in bone marrow and lymph nodes following necropsy revealed excellent immune reconstitution in both WT and BMAT-deficient mice. Adipocytes were numerous in the distal femur of WT mice but absent or rare in KitW/W-v mice. Bone parameters, including length, mass, density, bone volume, microarchitecture, and turnover balance, exhibited few differences between WT and BMAT-deficient mice. The minimal differences suggest that BMAT is not required for reconstitution of the immune system following lethal radiation and is not a major contributor to the skeletal phenotypes of kit signaling-deficient mice.
Myogenin Regulates DUSP13 to Inhibit Apoptosis Induced by Reactive Oxygen Species.

BACKGROUND Myogenin is well known as a crucial transcription factor in skeletal muscle development, yet its other biological functions remain unexplored. Previous research showed that myogenin suppresses apoptosis induced by angiotensin II in human induced pluripotent stem cell-derived cardiomyocytes, and offered a new perspective on myogenin's role in cardioprotection. However, the detailed mechanism of this cardioprotection, especially under oxidative stress, is still unclear. METHODS In this study, hydrogen peroxide (H2O2) was used to generate reactive oxygen species in myogenin-overexpressing cardiomyocytes. The apoptosis was examined by flow cytometry. Transcriptome sequencing (RNA-seq) was performed to identify genes regulated by myogenin. Western blotting was used to detect the protein level of DUSP13 and the phosphorylation level of p38 mitogen-activated protein kinase (MAPK). The dual-luciferase reporter assay and ChIP assay were used to confirm the binding of myogenin to the promoter region of DUSP13. DUSP13 overexpression and knockdown assays were performed to study its anti-apoptotic role. RESULTS Flow cytometry analysis of apoptosis showed that overexpressing myogenin for 24 and 48 hours decreased the apoptotic ratio by 47.9% and 63.5%, respectively, compared with untreated controls. Transcriptome sequencing performed on cardiomyocytes that expressed myogenin for different amounts of time (6, 12, 24, and 48 hours) identified DUSP13 as being up-regulated by myogenin. Western blotting showed that overexpression of myogenin increased the expression of DUSP13 and decreased the phosphorylation level of p38 MAPK. A dual-luciferase reporter assay proved that myogenin bound directly to the promoter region of DUSP13 and led to strong relative luciferase activity. Direct expression of DUSP13A and DUSP13B significantly reduced the rates of apoptosis and necrosis in cells treated with H2O2. Knockdown of DUSP13B significantly increased the rate of apoptosis in cells treated with H2O2. CONCLUSIONS The present findings suggest that myogenin might attenuate apoptosis induced by reactive oxygen species by up-regulating DUSP13 and inactivating the p38 MAPK pathway.
MovMe: Personalized Movie Information Retrieval

MovMe is a personalized movie information retrieval method that considers user comments and their ratings about movies. The central idea of MovMe is that a user’s movie preference can be identified by analyzing their past rating patterns and comments about movies. The performance of MovMe was compared with that of the other two methods based on tf-idf and user ratings. Using the online movie data available from Naver Movie, which is the largest movie portal in Korea, we ran an experiment in which 600 queries (20 queries for each of 30 users) were run to retrieve movies and the three methods were compared. The test results based on the mean values of user ratings of the first five movies from a list of movies retrieved by each retrieval method shows that MovMe is a better retrieval method than the other two methods in providing satisfying search results.
