This research is based on the characterization of khat waste (Catha edulis) through the use of some experimental approaches required to produce a clean, renewable energy source that could enhance our environmental economy as well as our energy security. The objective of this article is to characterize the pyrolysis khat waste in both proximate and ultimate analysis, thermal decomposition (weight loss of khat), and functional categories of khat waste, by using a Fourier transform infrared spectroscopy to determine the functional group of a sample. We also used an elemental analyzer device (model: Thermo Scientific–EA1112 FLASH CHNS/O analyzer) to measure elemental composition, characterize the proximate analysis of khat, and measure weight loss or thermal behavior of raw khat sample by using a device called thermogravimetric analyzer (TA instrument model: SDT Q600). The determined characterization of the khat sample was 48.25 percent carbon, 6.16 percent hydrogen, 45.13 percent oxygen, and 0.46 percent nitrogen. When compared to coal, khat contains extremely little nitrogen, resulting in less environmental contamination to the air than fossil fuel combustion. The proximate analysis results of the khat sample also showed 5 percent and 5.26 percent moisture content for both wet and dry bases, respectively, as well as 76.3 percent volatile matter, 4.8 percent ash content, and 13.83 percent fixed carbon. The findings are discussed in this research by comparing the final value results with other biomass and coil. The functional group of khat waste was studied using a spectrum of (65 Perkin Elmer) at wavelength ranges of 4000 to 400 cm-1. The weight loss of the khat sample at 700°C and a heating rate of 20°C/min, as well as the proximate analysis of this raw khat, were 4.5 percent, 75.84 percent, 5.38 percent, and 14.28 percent for moisture, unstable substance, ash content, and static carbon, respectively. The differences between TGA values and the projected proximal value were 10%, 0.6 percent, 9.47 percent, and 3.15 percent for moisture, volatile matter, as content, and fixed carbon, respectively. Overall, the benefit we get from pyrolysis of khat waste is that khat waste has very low nitrogen content and empty sulfur, which is very important for reducing air pollution and environmental sanitation when used as fuel. So from pyrolysis, khat waste types of fuel such as biochar, liquid fuel, and gas fuel can be obtained.

Objectives. To investigate how age, malnutrition, and the level of plasma cortisol and phosphate in patients with Parkinson’s disease (PD) at time of diagnosis are associated with body composition and handgrip strength in males and females compared to controls. Materials & Methods. This cross-sectional study includes baseline data from a cohort of newly diagnosed patients with Parkinson’s disease (N = 75; M/F = 41/34) in the New Parkinsonism in Umeå study (NYPUM). Body Impedance (BIS), handgrip strength (HGS) assessments, and evaluation of risk for malnutrition (Mini Nutritional Assessment (MNA) score) and cognitive performance (Mini-Mental State Examination (MMSE)) were performed at time of PD diagnosis. Results. Low fat-free mass index (FFMI), MNA score, and a high Unified Parkinson’s Disease Rating Scale (UPDRS-total and UPDRS-III) were associated with high daytime levels of P-cortisol in total PD population but not in controls. Partial correlations reveal that high fat mass percent (FM (%)) and low FFMI were associated with older age in males with PD but not females with PD. Risk of malnutrition was associated with P-cortisol in males but not in females with PD (r = −0.511,

P

, and n = 41 and r = −0.055,

P

, and n = 34, respectively). Multiple linear regressions show that an interaction between P-cortisol and P-phosphate, older age, and high UPDRS-III score were associated with HGS in total patient population and males but not females. Conclusions. Age- and disease-associated risk factors that decrease muscle mass and HGS and increase FM (%) in patients with PD differ between males and females by an association with levels of cortisol and phosphate.

Infection control is a challenging task in the treatment of wounds and a rise in antimicrobial resistance wound pathogens which is a barrier for the wound regeneration rapidly. Therefore, there is an urgent requirement of novel antimicrobial agents to target the wound pathogens and their biofilms. Silver nanoparticles (AgNPs) are the predominant antimicrobial agent for wound treatment due to their broad spectrum antimicrobial potential against various wound pathogens. Silver nanoparticles (AgNPs) were prepared from aqueous Adenanthera pavonina seed extract. This extract plays as a reducing agent for reduction of silver nitrate to silver oxide nanoparticles. An absorption peak at 428 nm with characteristic feature of surface plasmon resonance was observed. The average size of AgNPs was found to be ~200 nm and cube in shape of AgNPs. FTIR data revealed the presence of phenolic groups that were responsible for reduction and stabilization of silver nanoparticles. Face centered cubic (FCC) crystalline structure was revealed from XRD relating to silver oxide (AgO) with good antibacterial potential. The antioxidant activity of extract increases when the concentration increases, and it can be used in the inhibition of free radicals at wound site. Antibacterial activities showed effective inhibition against various pathogens such as E.coli, Salmonella typhi, Sphingomonas, and Bacillus. Given this correspondence, the green synthesized AgNPs would be a potential antimicrobial agent for various wound treatments.

Authors: Ward Chad , Khalid Kiran , Rozette Nicole
Published: July 2022

We describe the case of a 5-year-old male who developed severe hyperactive delirium with aggressive violent behavior following the administration of IV levetiracetam for the treatment of status epilepticus on two occasions. The child’s symptoms ranged from attacking his parents and the intensive care staff. Risperidone was given without any improvement in symptoms. A high-dose continuous infusion of IV dexmedetomidine was administered, and his violent behavior and delirium significantly improved. The two episodes of hyperactive delirium following IV levetiracetam administration occurred at ages 3 and 5, resulting in extensive work up including laboratory testing and cranial imaging, along with cerebral spinal fluid analysis and were normal. IV dexmedetomidine provided rapid symptom relief to prevent harm for the child, staff, and family on both occasions.
Estradiol Supplement or Induced Hypertension May Attenuate the Angiotensin II Type 1 Receptor Antagonist-Promoted Renal Blood Flow Response to Graded Angiotensin II Administration in Ovariectomized Rats
Authors: Choopani Samira , Nematbakhsh Mehdi
Published: July 2022

Backgrounds. Estrogen replacement therapy (ERT) and hypertension may influence females’ renin-angiotensin system (RAS) and its components. The angiotensin II (Ang II) type 1 receptor (AT1R) antagonist (losartan) may promote renal blood flow (RBF), and it is widely used in the clinic to control hypertension. The main objective of this study was the effects of estradiol or induced hypertension on RBF response to Ang II in losartan-treated ovariectomized (OVX) rats. Methods. Two groups of OVX rats were treated with placebo (group 1) and estradiol (group 2) for period of four weeks, and another group of OVX rats was subjected to induce hypertension by two-kidney one clip (2K1C) model (group 3). All the groups were subjected to the surgical procedure under anesthesia, and AT1R was blocked by losartan. RBF and renal vascular resistance (RVR) responses to Ang II administration were determined and compared. Results. Mean arterial (MAP) and renal perfusion (RPP) pressures in group 3 and uterus weight (UT) in group 2 were significantly more than other groups ([Formula: see text]). Ang II infusion resulted in dose-related percentage change increase in RBF and decrease in RVR. However, these responses in the OVX-estradiol and OVX-hypertensive rats were significantly lower than in the OVX-control group ([Formula: see text]). For instance, at the dose of 1000 ng/kg/min of Ang II administration, the percentage change of RBF was [Formula: see text], [Formula: see text], and [Formula: see text] in the groups of 1 to 3, respectively. Conclusion. Losartan prescription in some conditions such as hypertension or ERT could worsen RBF and RVR responses to Ang II.
Real-World Long-Term Experience on Endoxifen in Bipolar Disorder with Psychotic Symptoms
Authors: Thanvi Vikas
Published: July 2022

Evidence suggests that inhibition of protein kinase C (PKC) signalling may have a contributing role in the treatment of bipolar affective disorder (BPAD). Endoxifen, an active metabolite of tamoxifen, is a potent direct PKC inhibitor. This report presents a severe case of a BPAD patient with a baseline Young Mania Rating Scale (YMRS) score of 49, associated family history and addiction to psychostimulants, with no improvement by the first and second-generation antipsychotics. Treatment with endoxifen 8 mg once a day showed improvement in manic symptoms with a YMRS score of 4 and a reduction in the use of psychostimulants as well as other antipsychotic concomitant medications. No adverse effects were noted up to 8-month follow-up. Long-term treatment with endoxifen is safe and effective in severe BPAD.
Human Umbilical Cord Mesenchymal Stem Cell-Derived Extracellular Vesicles Carrying MicroRNA-29a Improves Ovarian Function of Mice with Primary Ovarian Insufficiency by Targeting HMG-Box Transcription Factor/Wnt/β-Catenin Signaling
Authors: Gao Tian , Cao Yi , Hu Min , Du Ying
Published: July 2022

Background. Primary ovarian insufficiency (POI) is a female disease characterized by ovarian function loss under 40 years old. Transplantation of exosomes is an encouraging regenerative medicine method that has the potential for restoring ovarian functions post-POI with high efficiency. Therefore, we investigate the therapeutic efficacy and potential mechanisms of human umbilical cord mesenchymal stem cell- (UCMSC-) derived exosomes on ovarian dysfunction post-POI. Methods. The model of POI was established by intraperitoneal injection with 5 mg/kg cisplatin. The mouse ovarian function was detected by measuring the levels of anti-Mullerian hormone, follicle-stimulating hormone, and estradiol and detecting the morphological changes. For in vitro experiments, the characterization and identification of UCMSCs and UCMSC-derived exosomes were done by observation of morphologies and flow cytometry. To exclude the interference effect of nonspecific precipitation substances, UCMSCs were treated with RNase A or RNase A in combination with Triton X-100. Granulosa cell (GC) identification was performed using immunofluorescence. GC proliferation and viability were assessed using 5-ethynyl-2

′

-deoxyuridine (EdU) assays and Cell Counting Kit-8 (CCK-8), and GC apoptosis was calculated by flow cytometry. Gene expression and protein levels were evaluated using reverse transcription quantitative polymerase chain reaction (RT-qPCR) and western blotting. The binding relationship between miR-29a and HMG-box transcription factor (HBP1) was verified by luciferase reporter assays. Results. In vitro, the human UCMSC-derived exosomes carrying miR-29a upregulation promoted the proliferation of GCs and suppressed their apoptosis. In vivo, miR-29a upregulation reserved the mature follicles and restored the ovarian functions. miR-29a targeted HBP1 and negatively regulated its expression. HBP1 upregulation rescued the miR-29a upregulation-induced inhibition in GC apoptosis and inactivated the Wnt/β-catenin pathway. Conclusion. The exosomal miR-29a derived from human UCMSCs improves the ovarian function by targeting HBP1 and activating the Wnt/β-catenin pathway.

Background. Colorectal cancer (CRC) is among the most common cancers diagnosed worldwide. Although genome-wide association studies have effectively identified the genetic basis of CRC, there is still unexplained variability in genetic risk. Transcriptome-wide association studies (TWAS) integrate summary statistics from CRC genome-wide association studies (GWAS) with gene expression data to prioritize these GWAS findings and uncover additional gene-trait correlations. Methods. First, we carried out a post-GWAS analysis using summary statistics from a large-scale GWAS of CRC (

controls). Second, combined with the expression weight sets from GTEx (v7), susceptibility genes were identified with the FUSION software. Colocalization, conditional and fine-mapping analyses, phenome-wide association study (pheWAS), and Mendelian randomization were employed to further characterize the observed correlations. Results. In the post-GWAS analyses, we first identified new genome-wide significant associations: three genomic risk loci were identified at 8q24.21 (rs6983267,

). In addition, the TWAS also identified four loci statistically significantly associated with CRC risk, largely explained by expression regulation, including six candidate genes (DUSP10, POU5F1B, C11orf53, COLCA1, COLCA2, and GREM1-AS1). We further discovered evidence that low expression of COLCA2 is correlated with CRC risk with Mendelian randomization. Conclusions. We discovered novel CRC risk loci and candidate functional genes by merging gene expression and GWAS summary data, offering new insight into the molecular processes underlying CRC development. This makes it easier to prioritize potential genes for follow-up functional research in CRC.
SR9009 Regulates Acute Lung Injury in Mice Induced by Sepsis
Authors: Hu Ming , Zhang Li , Cao Jie , Jiang Yu , Liu Gang
Published: July 2022

Rev-Erbα is a nuclear heme receptor, transcriptional repressor, and critical component of the molecular clock that drives daily rhythms of metabolism. However, the roles of Rev-Erbα in acute lung injury (ALI) remain unclarified. Hence, the effect of Rev-Erbα on lung injury of sepsis mice is investigated here. The mice sepsis model is established using lipopolysaccharide (LPS) injection, and the expression levels of proinflammatory cytokines, such as tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6), and interleukin-10 (IL-10) in both RAW246.7 cells and lung tissues, are tested. The inflammatory response is obviously enhanced in LPS-constructed sepsis mice and alleviated by SR9009 agonist treatment. Cell-based experiments reveal that pharmacological activation of Rev-Erbα via SR9009 attenuates the LPS-induced inflammatory response by suppressing TLR4-regulated NF-κB activation. Sepsis induces the increase in W/D ratio; promotes the levels of malondialdehyde (MDA), lactic acid (LA), and superoxide dismutase (SOD); and inhibits the levels of glutathione (GSH), whereas SR9009 treatment could effectively yield beneficial effects on metabolism. In addition, SR9009 treatment ameliorates acidosis and hypoxemia by efficiently decreasing arterial PaCO2 and increasing arterial PaO2, SO2, HCO3–, lactic acid concentration, and blood PH. These findings confirm that SR9009 treatment can alleviate the sepsis-induced lung injury and targeting Rev-Erbα may represent a promising approach for the prevention and management of ALI.
miR-127-5p Targets JAM3 to Regulate Ferroptosis, Proliferation, and Metastasis in Malignant Meningioma Cells
Authors: Zhang Jing , Liu Zang , Dong Yipeng
Published: July 2022

Objective. Meningiomas are one of the most common primary tumors of the central nervous system. Most of them are benign and can be cured by surgery, while a few meningiomas are malignant. Ferroptosis gene characteristics might be associated with drug therapy and survival in patients with clinically aggressive, unresectable meningiomas. This study explored the mechanism of differentially expressed miRNAs and ferroptosis in meningioma to provide a new reference to treat meningioma. Methods. Bioinformatics analysis of differential miRNA profiles and functions in patients with meningioma was performed. The contents of lactate dehydrogenase (LDH), malondialdehyde (MDA), and Fe2+ were determined. Reactive oxygen species (ROS) values, as well as cell cycle changes, were analyzed by flow cytometry. The targets of miR-127-5p and JAM3 were detected by dual luciferase assays. Cell counting kit-8 (CCK8) and Transwell assays were used to analyze cell activity. Ki67 expression was analyzed by immunohistochemistry. Expression levels of miR-127-5p and JAM3 were analyzed by RT-qPCR. GPX4 expression was quantified by western blotting. Results. miR-127-5p was expressed at low levels in IOMM-Lee cells, while JAM3 was highly expressed in IOMM-Lee cells. A dual luciferase assay demonstrated that miR-127-5p could target JAM3. Upregulation of miR-127-5p in IOMM-Lee cells resulted in cell cycle arrest and inhibition of cell activity. Upregulation of miR-127-5p increased LDH, MDA, and ROS levels and Fe2+ content and inhibited the expression of GPX4 protein. Upregulation of JAM3 reversed the results of miR-127-5p upregulation. Conclusion. miR-127-5p regulated meningioma formation and ferroptosis through JAM3, providing insights for the development of new treatments for meningioma.
Simulation of the Electro-Superconducting System Based on the H Equation
Authors: Zhang Jun
Published: July 2022

In order to reduce the levitation energy consumption and increase the levitation air gap, a simulation study of the electrochemistry superconducting magnetic levitation system based on the H equation is proposed. Through finite element simulation, the magnetic field distribution, current distribution, force, and other characteristics of the magnetic suspension system in the superconducting gravimeter are obtained; the relationship between the force of the superconducting ball in the magnetic field and the height of the suspension body and the current of the suspension coil is analyzed; and the penetration rate, the magnetic gradient, penetration depth, and maximum magnetic induction intensity of the superconducting spherical surface of the single-coil electrochemistry superconducting magnetic levitation system are obtained by simulation calculation. Simulation results show that, at 1 s, we start to use 0.2 s, 0.4 s, 0.6 s, and 0.8 s time, respectively, to pass current into the floating coil until it reaches 4.4 A. The magnetic gradient of the electrochemistry superconducting magnetic levitation system using a single coil is too large to meet the requirements of gravity measurement, the penetration depth is much smaller than the thickness of the superconducting sphere, and the maximum magnetic field on the surface of the superconducting sphere is much smaller than the critical magnetic field value of the superconducting material, and no loss will occur. The critical magnetic field value of the superconducting sphere is much smaller than that of the superconducting sphere. The critical magnetic field value of the material will not quench, which verifies that the H equation can simulate the superconducting magnetic levitation system well and has a high simulation accuracy and efficiency.

Published: July 2022

Pesticidal agents such as entomopathogenic fungi and medicinal plant extracts can be used as a component of integrated pest management. Biocontrol agents such as fungal isolates can be used as a component of integrated pest management. An evaluation of plant extracts from Azadirachta indica and Justicia schimperiana and two strains of entomopathogenic fungi were carried out on Ethiopian rape (Brassica carinata) against two stages (adult and nymph) of cabbage insect pests (aphids) in the laboratory and greenhouse condition. The efficacies of different treatments were examined, and results were recorded for plant extracts and entomopathogenic fungi on cabbage aphids. A significant difference was observed in the mortality of aphid insect pests recorded at different intervals of days. The adult aphid was reduced gradually from 8.65/plant to 2.77/plant after six days of spraying with A. indica indicating the highest efficacy. Moreover, the adult aphids after spraying of entomopathogenic fungi (BEI1) reduced from 11.2/plant to 6.5/plant after six days of spraying at 1 × 108 conidia/mL, showing the highest efficacy. The present results suggest the possibility of using a combination of entomopathogenic fungi and plant extracts to manage Brevicoryne brassicae (aphids). It revealed that a given combination displayed considerable efficacy to reduce B. brassicae (aphids) infestation. From the result, the adult aphids sprayed with A. indica + BEI1 reduced from 7.01/plant to 1.74/plant after six days of spraying with the highest efficacy. Generally, maximum percent of mortality was identified in plant extract treatment next to coapplication against adult aphids on sixth day of application. Similarly, conidial suspension of entomopathogenic fungi was found to have high activities for adult aphids. Therefore, based on the present result, products of fungal isolates and plant extracts should be used for further tests against other insect pests.
Endotoxemic Shock: A Molecular Phenotype in Sepsis
Authors: Kellum John A. , Foster Debra , Walker Paul M.
Published: July 2022

Background: Marked heterogeneity exists among patients with sepsis, both in terms of distribution of organ dysfunction and its severity. Such heterogeneity could be explained by the presence of multiple subtypes of sepsis that may have important implications for treatment. Methods: Narrative review of published literature involving endotoxin from 1970 to 2022. Results: In humans, endotoxemia is most consistently associated with a specific pattern of organ failure including shock, endothelial dysfunction, acute kidney injury, and hepatic dysfunction. This pattern is consistent with complement activation and uncontrolled inflammation, two features of endotoxemia. Unbiased discovery using artificial intelligence also identifies a subtype of sepsis which features these same organ failures. Conclusion: Endotoxin appears to represent an important molecular phenotype of sepsis with unique clinical features and high mortality.
