Table1_Remdesivir in treating hospitalized patients with COVID-19: A renewed review of clinical trials.XLSX
Since December 2019, COVID-19 has spread across the world almost through 2.5 years. As of 16 June 2022, the cumulative number of confirmed cases of COVID-19 worldwide has reached 542.62 million, and the death toll has risen to 6.33 million. With the increasing number of deaths, it is urgent to find effective treatment drugs. Remdesivir, an investigational broad-spectrum antiviral drug produced by Gilead has been shown to inhibit SARS-CoV-2, in vitro and in vivo. This review is aimed to analyze the feasibility of remdesivir in COVID-19 and put forward the shortcomings of present clinical studies. We systematically searched PubMed and Web of Science up until 24 May 2022, using several specific terms such as “remdesivir” or “GS-5734” and “COVID-19” or “SARS-CoV-2” and retrieved basic researches and clinical studies of remdesivir in COVID-19. In this review, we summarized and reviewed the mechanism of remdesivir in SARS-COV-2, clinical trials of using remdesivir in COVID-19, analyzed the efficacy and safety of remdesivir, and judged whether the drug was effective for the treatment of COVID-19. In different clinical trials, remdesivir showed a mixed result in the treatment of COVID-19. It seemed that remdesivir shortened the time to recovery and had an acceptable safety profile. However, more clinical trials are needed to test the efficacy and safety of remdesivir.</p

Policy Interactions and Underperforming Emission Trading Markets in China
Emission trading is considered to
be cost-effective environmental
economic instrument for pollution control. However, the ex post analysis
of emission trading program found that cost savings have been smaller
and the trades fewer than might have been expected at the outset of
the program. Besides policy design issues, pre-existing environmental
regulations were considered to have a significant impact on the performance
of the emission trading market in China. Taking the Jiangsu sulfur
dioxide (SO<sub>2</sub>) market as a case study, this research examined
the impact of policy interactions on the performance of the emission
trading market. The results showed that cost savings associated with
the Jiangsu SO<sub>2</sub> emission trading market in the absence
of any policy interactions were CNY 549 million or 12.5% of total
pollution control costs. However, policy interactions generally had
significant impacts on the emission trading system; the lone exception
was current pollution levy system. When the model accounted for all
four kinds of policy interactions, the total pollution control cost
savings from the emission trading market fell to CNY 39.7 million
or 1.36% of total pollution control costs. The impact of policy interactions
would reduce 92.8% of cost savings brought by emission trading program
Study on the bond properties between basalt fiber-reinforced spontaneous combustion coal gangue concrete and BFRP bars
Microstructural characterization of spontaneous combustion coal gangue (SCCG), the hydration products and mechanism of spontaneous combustion coal gangue concrete (SCCGC) were discerned through microscopic analysis. The bond performance was assessed employing a central pull-out test on samples variably substituted with SCCG (0%, 25%, 50%, 75%, and 100%) and augmented with basalt fiber (BF) (0%, 0.1%, 0.15%, and 0.2%). The failure mode and bonding mechanism were also revealed by this test. The bond-slip curves were fitted by various bond-slip constitutive models and a suitable model was found for each section. As indicated by the results, SCCGC possessed a lower carbon content and higher Al and Si element contents. These elements would undergo secondary hydration reactions with CH, which could enhance the strength of the ITZ and the compactness of the bond interface between BFRP bars and concrete. The failure modes were splitting and pull-out. An inverse correlation was observed between bond strength and the increment in SCCG aggregate substitution, ranging from a decline of 2.6% to 23.1%. As the BF content increased, the bond strength and peak slip increased by 3.9% ∼ 19.7% and 4.0% ∼ 14.6%, respectively. Furthermore, the reinforcing effect of BF on bond strength increased from 3.9% ∼ 10.3% to 8.8% ∼ 19.7% as the SCCG replacement rate increased, which was noticeable. The Malvar model and the Continuous Curve model were the best fitting models for the ascending and descending sections of bond-slip curves, respectively, while the residual stage was well fitted by the Hao Qingduo model.</p

Carbon Nitride Quantum Dot-Based Thin-Film Nanocomposite Membranes for Efficient Dye Removal
Nanofiltration
(NF) has been widely studied as a promising approach
for dye wastewater treatment. However, low water permeance and membrane
fouling are still major challenges that most current NF membranes
face. Herein, we developed a thin-film nanocomposite (TFN) membrane
incorporating graphitic carbon nitride quantum dots (CNQDs) via a
facile interfacial polymerization method. The introduction of CNQDs
not only results in a thin and loose PA active layer that facilitates
rapid water transport but also provides additional water channels
via their triangular nanopores. As a result, the TFN membrane exhibits
a significant increase in permeation flux (210%) while maintaining
a high rejection of methyl blue (96%) compared to the pristine thin-film
composite membrane. Moreover, the newly developed membrane demonstrates
excellent antifouling properties for bovine serum albumin, humic acid,
and lysozyme due to the synergistic effects of enhanced surface hydrophilicity
and reduced surface roughness resulting from the CNQD incorporation.
These findings highlight the great potential of CNQDs in designing
TFN membranes with a high separation performance and antifouling properties
for efficient dye removal

Cobratoxin Alleviates Cancer-Induced Bone Pain in Rats via Inhibiting CaMKII Signaling Pathway after Acting on M4 Muscarinic Cholinergic Receptors
Cancer-induced bone pain (CIBP) is
a common pain in clinics, which
can reduce the quality of life and increase the mortality of patients,
but the treatment of CIBP is limited. This study was designed to investigate
the analgesic effect of α-cobratoxin on CIBP and further to
explore the molecular target and potential signal pathway. As shown
by the mechanical allodynia test in a CIBP rat model, administration
of α-cobratoxin produced significant analgesia in a dose-dependent
manner, and the analgesic effects were blocked by pretreatment with
an intrathecal injection of M4 mAChR-siRNA or intraperitoneal injection
of tropicamide, an antagonist of M4 muscarinic cholinergic receptor.
Whole-cell patch-clamp recording showed that α-cobratoxin can
decrease the spontaneous firing and spontaneous excitatory postsynaptic
currents of SDH neurons in CIBP rats. In primary lumber SDH neurons,
intracellular calcium measurement revealed that α-cobratoxin
decreased intracellular calcium concentration, and immunofluorescence
demonstrated that M4 muscarinic cholinergic receptor and CaMKII/CREB
were co-expressed. In the CIBP model and primary SDH neurons, Western
blot showed that the levels of p-CaMKII and p-CREB were increased
by α-cobratoxin and the effect of α-cobratoxin was antagonized
by M4 mAChR-siRNA. The quantitative polymerase chain reaction (qPCR)
results showed that α-cobratoxin downregulated the expression
of proinflammatory cytokines through M4 muscarinic cholinergic receptor
in SDH. These results suggest that α-cobratoxin may activate
M4 muscarinic cholinergic receptor, triggering the inhibition of SDH
neuronal excitability via CaMKII signaling pathway, thereby resulting
in antagonistic effects in the CIBP rat model
Impact of 1,25(OH) 2 D 3 on TG content in liver of rats with type 2 diabetes
<div><p>Abstract Purpose: To evaluate the effects of 1,25 dihydroxy vitamin D3 (1,25(OH)2D3) on the content of triglyceride (TG), as well as on the gene and protein expressions of adiponectin receptor 2 (AdipoR2), p38 mitogen-activated protein kinase (P38MAPK), and lipoprotein lipase (LPL) in the liver of rats with type 2 diabetes mellitus (T2DM) so as to provide theoretical basis for exploring the mechanism by which 1,25(OH)2D3 regulates TG. Methods: Wistar rats were divided into four groups (n=25), with different treatments and detected the gene and protein expressions of AdipoR2, p38MAPK, and LPL in the liver tissue by reverse transcription polymerase chain reaction (RT-PCR) and Western blotting. Meanwhile, the content of TG in the liver tissue was detected by the Enzyme-linked immunosorbent assay. Results: The expression of AdipoR2, p38MAPK, LPL gene and protein in the liver of VitD intervention group was significantly higher than that in T2DM group (P <0.05), while the TG content was significantly lower than that in T2DM group (P <0.05). Conclusion: 1,25(OH)2D3 can decrease the content of TG in the liver, and its mechanism may be achieved by upregulating the expressions of AdipoR2, p38MAPK, and LPL in the liver.</p></div
