observed in this patient's postoperative course. Finally, closure of the patient's colostomy was successfully performed. CONCLUSIONS MCA with side-to-side anastomosis generated a wide anastomosis in a short time.Soil plays a vital role in the climate system. This paper performs decision tree regression to estimate soil moisture (SM) by considering different parameters that include air temperature, time, relative humidity, and soil temperature. Besides, this paper investigates the effects of the parameters of decision tree regression by utilizing the response surface. The obtained estimation results of two distinct soil areas, Field and Forest, indicate that two different soil areas have distinct estimation quality. Epigenetic activity Furthermore, numerical results of the training stage show that the estimation of SM for Field and Forest soil performing decision tree regression offers 0.0019 and 0.0025 mean absolute error (MAE), respectively. Moreover, numerical results show that the interaction of the parameters of the performed algorithm plays a vital role in the estimation stage of Field and Forest soils.A ratiometric fluorescent assay is fabricated for the evaluation of alkaline phosphatase (ALP) activity. This assay is composed of ionic liquid-functionalized carbon dots (IL-CDs) with blue fluorescence signal at 470 nm and 2,3-diaminophenazine (DAP) with yellow fluorescence signal at 570 nm. IL-CDs were synthesized via electrochemical method by using ionic liquid (1-butyl-3-methylimidazolium tetrafluoroborate) and ultrapure water as precursors. DAP is produced by the oxidation reaction between o-phenylenediamine and H2O2 under the catalysis of horseradish peroxidase. H2O2 is reduced by ascorbic acid which is the hydrolysis product of ascorbic acid 2-phosphate under the catalysis of ALP, finally reducing the amount of DAP. The activity of ALP is evaluated through the ratiometric fluorescent signal between IL-CDs and DAP via Förster resonance energy transfer. Under optimal experimental conditions, this ratiometric fluorescent assay has a response that covers the 0.04 to 3.2 U L-1 (12 to 960 pM) ALP activity. This assay possesses ultralow detection limit of 0.012 U L-1 (3.6 pM) for ALP and high selectivity for ALP among several enzymes. The method was used to measure ALP activity in human serum samples with satisfying results.

This ratiometric fluorescent assay possessed low detection limit of ALP activity (0.012 U L-1) and high selectivity among several enzymes.A pilot study on the use of P-EU to identify patients without osteoporosis and/or a subclinical vertebral fracture after a recently sustained non-vertebral fracture (NVF). INTRODUCTION Screening with portable devices at emergency departments or plaster rooms could be of interest to limit referrals for dual X-ray absorptiometry (DXA) and vertebral fracture assessment (VFA). We calculated the number of negative tests for osteoporosis and/or subclinical vertebral fractures (VFs) using pulse-echo ultrasonometry (P-UE) at different thresholds. PATIENTS AND METHODS In this cross-sectional study, 209 consecutive women of 50-70 years with a recent non-vertebral fracture (NVF) were studied at the Fracture Liaison Service (FLS) of one hospital. All women received DXA/VFA and P-EU (Bindex®) assessments. Various P-EU thresholds (based on the density index (DI, g/cm2)) were analyzed to calculate the best balance between true negative (indeed no osteoporosis and/or subclinical VF) and false negative tests (osteoporosis and/or subclinical VF according to DXA/VFA). RESULTS Eighty-three women had osteoporosis (40%) and 17 women at least one VF (8%). Applying the manufacturer's recommended P-EU threshold (DI 0.844 g/cm2) being their proposed cut-off for not having hip osteoporosis resulted in 77 negative tests (37%, 31% true negative and 6% false negative tests). A DI of 0.896 g/cm2 resulted in 40 negative tests (19.3%) (38 true negative (18.3%) and 2 false negative tests (1.0%)). CONCLUSION The application of P-EU enables the identification of a substantial proportion of women with recent non-vertebral fractures at the FLS who would not need a DXA/VFA referral because they had no osteoporosis and/or subclinical vertebral fractures. The most conservative P-EU threshold resulted in 18.3% true negative tests verified by DXA/VFA against 1% false negative test results.PURPOSE OF REVIEW Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the virus responsible for the aggressive coronavirus disease (COVID-19) pandemic. Recently, investigators have stipulated that COVID-19 patients receiving angiotensin-converting-enzyme inhibitors (ACEI) may be subject to poorer outcomes. This editorial presents the available evidence to guide treatment practices during this pandemic. RECENT FINDINGS Recent studies from Wuhan cohorts provide valuable information about COVID-19. A cohort with 52 critically ill patients revealed cardiac injury in 12% of patients. Worse outcomes appear to be more prevalent in patients with hypertension and diabetes mellitus (DM), possibly due to overexpression of angiotensin-converting enzyme 2 (ACE2) receptor in airway alveolar epithelial cells. Investigators suspect that SARS-CoV-2 uses the ACE2 receptor to enter the lungs in a mechanism similar to SARS-CoV. Several hypotheses have been proposed to date regarding the net effect of ACEI/ARB on COVID-19 infections. Positive effects include ACE2 receptor blockade, disabling viral entry into the heart and lungs, and an overall decrease in inflammation secondary to ACEI/ARB. Negative effects include a possible retrograde feedback mechanism, by which ACE2 receptors are upregulated. Even though physiological models of SARS-CoV infection show a theoretical benefit of ACEI/ARB, these findings cannot be extrapolated to SARS-CoV-2 causing COVID-19. Major cardiology scientific associations, including ACC, HFSA, AHA, and ESC Hypertension Council, have rejected these correlation hypotheses. After an extensive literature review, we conclude that there is no significant evidence to support an association for now, but given the rapid evolvement of this pandemic, findings may change.
