These results indicated that the application of Pantoea sp. PP4 can facilitate the phytoremediation of Pb and Cd in oligotrophic growth substrates, forming a convergent bacterial community. Our findings highlighted the importance of identifying ideal PSB to improve phytoremediation efficiency in oligotrophic environments.Air pollution is associated with many neurodevelopmental and neurological disorders in human populations. Rodent models show similar neurotoxic effects of urban air pollution ultrafine particulate matter (UFPs  less then  100 nm (PM0.1)), collected by different methods or from various sources. Exposure to ultrafine particulate matter (UFPs  less then  100 nm (PM0.1)) can be adversely impacting the central nervous system (CNS) by the activation of proinflammatory pathways and reactive oxygen species associated with air pollution particulate matter. We investigated hippocampal inflammatory cytokines, neurobehavioral alteration, and neuronal morphology following exposure to diesel exhaust particles (DEPs) in mice. Male mice were DEPs exposed for 14 weeks. Mice exposed to DEPs showed more disorders in spatial memory and learning and depressive-like responses than control mice. Expression of hippocampal pro-inflammatory cytokine was increased among DEPs exposure mice. The density of neurons in hippocampus CA1, CA3, and dentate gyrus (DG) regions decreased in DEPs mice. Overall, these findings show that prolonged exposure to DEPs in the world's major cities can alter neurobehavioral and impair cognition.Hand foot and mouth disease (HFMD) is a widespread public health concern but the studies on air pollution and the lengths of hospital stay (LOS) of HFMD are scarce nevertheless. Clinic demographic features among 5135 hospitalized HFMD cases in Nanjing, China, had been characterized from 2012 to 2017. Then, we had analyzed the association between PM2.5 short-term exposure as well as its components (OM, BC, SO42-, NH4+, NIT, SOIL, and SS) and the LOS of HFMD. Among these cases that were involved in our study, 98.62% were aged 0-6 years old, and 3772 (73.46%) were hospitalized within 1 week or less. The LOS of HFMD patients was different in various age ranges, illness onset years, and illness onset seasons (P  less then  0.01). For per IQR increase in PM2.5 concentrations, LOS of HFMD increased by 0.52 (0.33, 0.71), 0.50 (95% CI, 0.31-0.69) and 0.46 (95% CI, 0.28-0.65) day in adjusted models at lag 3 days, lag 7 days, and lag 14 days, respectively. In addition, per IQR increase of BC, SO42-, NH4+, NIT, and SOIL was also significantly associated with the LOS of HFMD. Our findings corroborated that short-term PM2.5 exposure was associated with the increased LOS of HFMD, and its components (BC, SO42-, NH4+, NIT, and SOIL) of PM2.5 might play a key role in prolonged LOS of HFMD.Energy consumption and CO2 emissions are agreed as the main causes of global warming and climate change, which are causing several extreme weather events in recent decades. However, there is little understanding how humans adjust their behaviours in energy consumption and emissions in responding to these natural threats. This study aims to examine the influences of exposure, susceptibility, and vulnerability to five natural hazards on CO2 emissions, energy intensity, renewable energy, and electricity consumption. The feasible generalized least squares model and several panel estimates are applied for a global sample of 161 countries from 2011 to 2018. The empirical results provide interesting findings. First, exposure, susceptibility, and vulnerability appear to reduce electricity usage, renewable energy consumption, energy intensity, and CO2 emissions in the global sample. Second, the negative effects of exposure, susceptibility, and vulnerability are consistent across four income groups (high-income; upper-middle-income; lower-middle-income; and low-income) except for some interesting differences. Exposure appears to increase renewable energy consumption significantly in upper-middle and high-income, while susceptibility has a significant positive influence on renewable energy consumption in low-, upper-middle, and high-income. Third, the negative impact is also documented in seven regions, with the exception of some interesting findings threats from nature appear to increase CO2 emissions and energy intensity in the Middle East and North Africa, South Asia, and Europe and Central Asia, while they stimulate the use of renewable energy in Latin America and Caribbean. Interestingly, exposure and susceptibility appear to induce renewable energy transformation in Europe and Central Asia.Nowadays, modern industries generate their energy by using renewable solar. The rapid increase in photovoltaic (PV) module installations provides a better energy conversion, but their life cycle is a major concern. This research paper focuses on the recycling process for solar PV modules using the Internet of Things in industries. The smart bin with the Internet of Things (IoT) utilizes a machine learning approach to collect solar waste. The proposed smart bin uses k-Nearest Neighbor's algorithm (k-NN) and Long Short-Term Memory (LSTM), a network-based learning algorithm. These algorithms are useful in updating the level of the bin via alert messages. It also helps in identifying the type of waste material. The k-NN algorithm provides 83% accuracy in predicting the bin level in a real-time testing environment. The smart dust bin classifies the waste materials, and notifies its level to the collection center through the IoT platform when the level reaches a prescribed threshold, the signal corresponding to the level is passed to the common waste collection unit. IoT is connected to Cloud Server. It helps to predict the level of the smart bin. Delay is introduced in the order of 3-8 s while the alert message is sent to the common waste collection unit. The system monitors the smart bin levels and sends the notifications to alert and initiate the collection unit. Real-time mobile app monitors the bin's level and location. The cloud IoT analytics analyze the solar e-waste in a different locations in industries.The proposed system works better and provides accurate results by using machine learning approach.

To determine which Thyroglobulin (Tg) level after levothyroxine (LT

) withdrawal (stimulated thyroglobulin - sTg) measured before radioiodine therapy (RAIT) is able to predict incomplete response to treatment of differentiated thyroid carcinoma (DTC) with greater sensitivity and specificity one year after initial treatment with I

.

A chart review was performed in which 375 patients with DTC treated with RAIT were included. The sTg was measured in all patients prior to treatment with I

. Follow up were then performed one year later. Initial sTg levels were associated to DTC outcomes. A receiver operating characteristic (ROC) curve was performed to achieve a sTg level able to predict which patients would have a greater chance of having an incomplete response to RAIT.

Incomplete response to treatment was found in 122 patients (32.5%), this group had a mean sTg of 23.2 ng/mL. ROC curve showed that the optimal cut-off sTg level was 4.4 ng/mL. (sensitivity 72.1%; specificity 72.3%; accuracy 72.2%; positive predictive value of 55.7%; and negative predictive value 84.3%).

sTg pre-ablation is a valuable predictor of DTC incomplete response to treatment one year after RAIT. Levels of 4.4 ng/ml or more showed higher accuracy to predict this outcome.

Metformin (MF) intake associates with reduced levels of circulating low-density lipoprotein-cholesterol (LDL-C). This has been attributed to the activation of AMPK, which differentially regulates the expression of multiple genes involved in cholesterol synthesis and trafficking. However, the exact mechanism underlying the LDL-C lowering effect of MF remains ambiguous.

MF-treated Hep-G2 and HuH7 cells were evaluated for cell viability and the expression status of key lipid metabolism-related genes along with LDL-C uptake efficiency.

MF treatment resulted in decreased expression and secretion of PCSK9, increased expression of LDLR and enhanced LDL-C uptake in hepatocytes. It also resulted in increased expression of activated AMPK (p-AMPK) and decreased expression of SREBP2 and HNF-1α proteins. Transcriptomic analysis of MF-treated Hep-G2 cells confirmed these findings and showed that other key lipid metabolism-related genes including those that encode apolipoproteins (APOB, APOC2, APOC3 and APOE), MTTP and LIPC are downregulated. Lastly, MF treatment associated with reduced HMG-CoA reductase expression and activity.

These findings suggest that MF treatment reduces circulating LDL-C levels by suppressing PCSK9 expression and enhancing LDLR expression; hence the potential therapeutic utility of MF in hypercholesterolemia.

The reporting quality of RCTs is of fundamental importance for readers to appropriately analyse and understand the design and results of studies which are often labelled as practice changing papers. The aim of this article is to assess the reporting standards of a representative sample of randomised controlled trials (RCTs) published between 2019 and 2020 in four of the highest impact factor general medical journals. A systematic review of the electronic database Medline was conducted. Eligible RCTs included those published in the New England Journal of Medicine, Lancet, Journal of the American Medical Association, and British Medical Journal between January 1, 2019, and June 9, 2020. The study protocol was registered on medRxiv ( https//doi.org/10.1101/2020.07.06.20147074 ). Of a total eligible sample of 497 studies, 50 full-text RCTs were reviewed against the CONSORT 2010 statement and relevant extensions where necessary. The mean adherence to the CONSORT checklist was 90% (SD 9%). There were specific items on the CONSORT checklist which had recurring suboptimal adherence, including in title (item 1a, 70% adherence), randomisation (items 9 and 10, 56% and 30% adherence) and outcomes and estimation (item 17b, 62% adherence). Amongst a sample of RCTs published in four of the highest impact factor general medical journals, there was good overall adherence to the CONSORT 2010 statement. However there remains significant room for improvement in areas such as description of allocation concealment and implementation of randomisation.B-cell lymphoma 2 (Bcl2) is a key protein regulator of apoptosis. The hydrophobic groove in Bcl2 is a unique structural feature to this class of enzymes and found to have a profound impact on protein overall structure, function, and dynamics. N6F11 mw Dynamics of the hydrophobic groove is an essential determinant of the catalytic activity of Bcl2, an implicated protein in Waldenström macroglobulinemia (WM). The mobility of α3-α4 helices around the catalytic site of the protein remains crucial to its activity. The preferential binding mechanisms of the multi-catalytic sites of the Bcl2 enzyme have been a subject of debate in the literature. In addition to our previous report on the same protein, herein, we further investigate the preferential binding modes and the conformational implications of Venetoclax-JQ1 dual drug binding at both catalytic active sites of Bcl2. Structural analysis revealed asymmetric α3-α4 helices movement with the expansion of the distance between the α3 and α4 helix in Venetoclax-JQ1 dual inhibition by 15.
