Abstract
Disinfectants and antibiotics are widely used for the prevention and control of bacterial infectious diseases. Frequent disinfection is thought to exacerbate antibiotic resistance. However, little is known about how disinfectants and antibiotics co-induce changes in the soil antibiotic resistance genes (ARGs). This study determined the ARG profiles and bacterial community dynamics between unamended soil and manure-amended soil exposed to benzalkonium chloride (C12) (BC, 10 mg kg-1) disinfectant and sulfamethazine (SMZ, 1 mg kg-1), using high-throughput quantitative PCR and 16 S rRNA gene sequencing. Manure application enriched the soil in terms of ARGs abundance and diversity, which synergistically amplified the co-selection effect of BC and SMZ on soil antibiotic resistome. Compared with the control treatment, BC and SMZ exposure had a smaller impact on the bacterial infectious diseases and antimicrobial resistance-related functions in manure-amended soil, in which bacterial communities with greater tolerance to antimicrobial substances were constructed. Manure application increased the proportion of rank I ARGs and potential human pathogenic bacteria, while BC and SMZ exposure increased the drug-resistant pathogens transmission risk. This study validated that BC and SMZ aggravated the antimicrobial resistance under manure application, providing a reference for managing the spread risk of antimicrobial resistance in agricultural activities.

Abstract
BACKGROUND A noninvasive, safe, and economic imaging technique is required to identify epileptogenic lesions in the brain. PURPOSE Our aim was to perform a meta-analysis evaluating the accuracy of arterial spin-labeling in localizing the epileptic focus in the brain and the changes in the blood perfusion in these regions. DATA SOURCES Our sources were the PubMed and EMBASE data bases. STUDY SELECTION English language studies that assessed the diagnostic accuracy of arterial spin-labeling for detecting the epileptogenic zone up to July 2019 were included. DATA ANALYSIS The symptomatogenic foci of seizures in the brain were determined and used as the references. The relevant studies were evaluated using the Quality Assessment of Diagnostic Accuracy Studies-2 tool. The outcomes were evaluated using the pooled sensitivity, pooled specificity, pooled accuracy, diagnostic odds ratio, area under the summary receiver operating characteristic curve, and likelihood ratio. DATA SYNTHESIS Six studies that included 174 patients qualified for this meta-analysis. The pooled sensitivity, pooled specificity, and area under the summary receiver operating characteristic curve were 0.74 (95% CI, 0.65-0.82), 0.35 (95% CI, 0.03-0.90), and 0.73 (95% CI, 0.69-0.76), respectively. The accuracy of arterial spin-labeling for localizing the epileptic focus was 0.88 (accuracy in arterial spin-labeling/all perfusion changes in arterial spin-labeling) in cases of a positive arterial spin-labeling result. The epileptogenic zone exhibited hyperperfusion or hypoperfusion. LIMITATIONS Only a few studies were enrolled due to the strict inclusion criteria. CONCLUSIONS Arterial spin-labeling can be used for assessing, monitoring, and reviewing, postoperatively, patients with epilepsy. Blood perfusion changes in the brain may be closely related to the seizure time and pattern.

Abstract
Using first-principles transport calculations, we predict that the anisotropic magnetoresistance (AMR) of single-crystal Co_{x}Fe_{1-x} alloys is strongly dependent on the current orientation and alloy concentration. An intrinsic mechanism for AMR is found to arise from the band crossing due to magnetization-dependent symmetry protection. These special k points can be shifted towards or away from the Fermi energy by varying the alloy composition and hence the exchange splitting, thus allowing AMR tunability. The prediction is confirmed by delicate transport measurements, which further reveal a reciprocal relationship of the longitudinal and transverse resistivities along different crystal axes.

Abstract
Circular ATP binding cassette subfamily B member 10 (circABCB10) has been identified to have oncological functions in several tumors. However, the roles of circABCB10 in rectal cancer remain unknown. The expression of circABCB10, microRNA (miR)-326 and C-C motif chemokine ligand 5 (CCL5), and apoptosis related-protein was detected using quantitative real-time polymerase chain reaction or western blot, respectively. Cell survival or apoptosis was measured using cell counting kit-8 assay or flow cytometry. The accumulations of intracellular lipid reactive oxygen species (ROS) and Fe2+ were analyzed using C11-BODIP dye or iron kit assay, respectively. In vivo experiments were conducted using the murine xenograft model. The interaction between miR-326 and circABCB10 or CCL5 was confirmed by dual-luciferase reporter assay and RNA immunoprecipitation assay. CircABCB10 and CCL5 were upregulated but miR-326 was downregulated in rectal cancer. The knockdown of circABCB10 promoted rectal cancer cell ferroptosis and apoptosis in vitro as well as inhibited tumor growth in vivo. miR-326 was a target of circABCB10, and the miR-326 inhibition could partially attenuate circABCB10 deletion-induced cell ferroptosis and apoptosis. miR-326 directly interacted with CCL5, and the miR-326 inhibition suppressed cell ferroptosis and apoptosis by targeting CCL5. Besides, we observed that miR-326 was negatively regulated by circABCB10, while CCL5 was positively regulated by it, and circABCB10 served as a sponge of miR-326 to regulate the CCL5 expression in rectal cancer cells. CircABCB10 silence promoted rectal cancer cell ferroptosis and apoptosis by regulating the miR-326/CCL5 axis, suggesting a potential therapeutic target for rectal cancer therapy.

Abstract
We present the ultralow-temperature specific heat and thermal conductivity measurements on single crystals of triangular-lattice compound EtMe_{3}Sb[Pd(dmit)_{2}]_{2}, which has long been considered as a gapless quantum spin liquid candidate. In specific heat measurements, a finite linear term is observed, consistent with the previous work [S. Yamashita et al., Nat. Commun. 2, 275 (2011)NCAOBW2041-172310.1038/ncomms1274]. However, we do not observe a finite residual linear term in the thermal conductivity measurements, and the thermal conductivity does not change in a magnetic field of 6 T. These results are in sharp contrast to previous thermal conductivity measurements on EtMe_{3}Sb[Pd(dmit)_{2}]_{2} [M. Yamashita et al., Science 328, 1246 (2010)SCIEAS0036-807510.1126/science.1188200], in which a huge residual linear term was observed and attributed to highly mobile gapless excitations, likely the spinons of a quantum spin liquid. In this context, the true ground state of EtMe_{3}Sb[Pd(dmit)_{2}]_{2} has to be reconsidered.

Abstract
BACKGROUND AND PURPOSE Brain function and microstructure are affected by alcohol consumption. Until recently, the effect of alcohol on neural mechanisms has not been fully elucidated. Our aim was to explore the acute effects of alcohol on healthy human brains by diffusional kurtosis imaging and 3D arterial spin-labeling and elucidate structural and functional changes in the brain on acute alcohol intake. MATERIALS AND METHODS Conventional MR imaging, diffusional kurtosis imaging, and 3D arterial spin-labeling were performed on 24 healthy volunteers before and 0.5 and 1 hour after drinking alcohol. Participants were divided into 2 groups according to the response to alcohol: blushing (n = 12) and unblushing (n = 12) groups. Twenty brain regions were analyzed. RESULTS Diffusional kurtosis imaging revealed an increase in mean kurtosis and fractional anisotropy at 0.5 hour post-alcohol intake in most brain regions, whereas mean diffusion was decreased in several brain regions at 1 hour after drinking. 3D arterial spin-labeling showed increased cerebral blood flow in most brain regions, particularly in the frontal regions. However, perfusion in the anterior commissure decreased. Regional changes in the brain correlated with various behavioral performances with respect to blush response and sex. In general, blushing individuals and men are more sensitive to alcohol with acute effects. CONCLUSIONS Physiologic and microstructural alterations in the brain on alcohol consumption were examined. Brain areas with blood flow alteration detected by 3D arterial spin-labeling were highly consistent with susceptible areas detected by diffusional kurtosis imaging. The current study provides new insight into the effects of alcohol on the brain and behavioral performance in different blush response and sex populations.

Abstract
Objective: To provide a reference for a suitable alternative treatment choice for implant-supported prostheses, and to explore the influence of 3 types of prosthetic material on the stress distribution around implant. Methods: The implant-abutment analogs were embedded individually into photoelastic resin blocks, which were medical pure titanium castings reproducing the surface and outline of implant (diameter 4.3 mm, length 11.5 mm) and esthetic abutment (regular profile, 1 mm). The prostheses were divided into 3 groups according to the type of prosthetic material. Each group consisted of 5 samples. The samples of composite resin ceramic and zirconia group were milled by chair-side computer aided design and computer aided manufacture (CAD/CAM) system. The samples of porcelain-fused-to-metal crown group were made manually and a pre-arranged silicone rubber impression of CAD/CAM crown would guide to shape the veneer porcelain. Each set was submitted to a 300 N compressive load axially or obliquely (75°). The stress value in the peri-implant bone at the level of the neck, neck1/3, middle1/3 and root1/3 of the sections (0.5, 1.5, 2.5, 3.5 mm) from implant was analyzed by digital photoelasticity, and the stress cushioning effect of 3 types of prosthetic material was comprehensively evaluated. Results: The time spent reaching the stress peak of composite resin ceramic group [(1.58±0.08) s, axially; (2.75±0.21) s, obliquely] was larger than that of the zirconia group [(1.40±0.12) s, axially; (2.30±0.25) s, obliquely] (P<0.05) under the same download mode. Although there were no significant differences in equivalent stress values of the measurement points among the three groups (P>0.05), a downward trend of equivalent stress values of composite resin ceramic group was observed compared to zirconia group, regardless of load type. When loaded obliquely, the highest degree of stress concentration at the level of the neck of implant were found in the porcelain-fused-to-metal crown group. Conclusions: Within the limitations of this study, composite resin ceramic was more beneficial to the biomechanical behavior of implant in stress buffer compared to zirconia.

Abstract
OBJECTIVE To evaluate the effects of intubating laryngeal mask airway (ILMA) in prediction of extubation responses in patients with hypertensive cerebral hemorrhage during general anesthesia recovery period. METHODS A total of 120 patients with hypertensive cerebral hemorrhage aged 47-71 years, with Glasgow Coma Scale (GCS)11-15 scores and American Society of Anesthesiologists (ASA) physical status Ⅰ or Ⅱ, undergoing craniotomy surgery from December 2012 to December 2014 in the Affiliated First Municipal Hospital of Fujian Medical University were randomly divided into 2 groups (n=60): tracheal intubation (Group T) and intubating laryngeal mask airway (Group I), by using a random number table. Variations of invasive arterial blood pressure and responses of endotracheal extubation were compared between two groups before and after extubation. RESULTS There were no significant differences in ages, sex ratio, preoperative GCS, operation time and the time from the end of operation to Train of Four stimulation (TOF) becoming to 4 between the two groups. The mean arterial pressure (MAP) at the time point of extubation (T3), 1 min (T4), 3 min (T5), 5 min (T6) after extubation were (136±20), (130±16), (128±12), (125±10) mmHg in Group T, and heart rate(HR) at these four time points were (105±11), (96±8), (92±7), (86±6) bpm, respectively. While in group I, MAP were (108±10), (106±8), (105±9), (106±7) mmHg, and HR were (75±8), (76±7), (68±5), (67±6) bpm, respectively. MAP and HR of the two groups at these four time points had significant differences (T3: t=10.91, 17.20; T4: t=13.72, 14.69; T5: t=12.54, 13.35; T6: t=13.39, 11.27; all P<0.01). During recovery, the incidences of extubation responses of group T and group I were 92% and 2%, respectively, and the difference had statistically significant (χ(2)=94.05, P<0.01). The incidences of coughing of group T and group I were 97% and 0, respectively, and the difference had statistically significant (χ(2)=148.69, P<0.01). CONCLUSION Compared with tracheal intubation, ILMA can decrease the incidence of extubation responses and coughing in patients with hypertensive cerebral hemorrhage during general anesthesia recovery period, and avoid cere-brovascular accidents.

Abstract
Aptamers that recognize the IgG Fc region are of great interest because of their wide application as an immunology probing tool, for diagnostics, and as affinity agents for antibody purification. We developed a target replacement strategy as a modification of conventional Systematic Evolution of Ligands by EXponential enrichment (SELEX) in order to efficiently select and identify novel DNA aptamers against the Fc region of mouse IgG. In this new approach, multiple IgG subclasses (IgG1, IgG2a, mouse IgG Fc, and anti-HBs IgG) were sequentially used to select aptamers in one continuous SELEX. After 8 rounds of selection, the aptamers were analyzed using dot blot and an electrophoretic mobility shift assay, which showed universal binding capability to different IgG subclasses. Secondary structure analysis of the aptamers indicated that the stem-loop structure of the aptamers play an important role in binding to the common site in different mouse IgG subclasses. This demonstrated the feasibility of using multiple target replacement SELEX for the selection of aptamers. This target replacement strategy is also expected to be useful for selecting aptamers that bind common regions of molecules other than antibodies.

Abstract
Atomistic computer-simulation evidences are presented for the possible existence of one-dimensional silicon nanostructures: the square, pentagonal, and hexagonal single-walled silicon nanotubes (SWSNTs). The local geometric structure of the SWSNTs differs from the local tetrahedral structure of cubic diamond silicon, although the coordination number of atoms of the SWSNTs is still fourfold. Ab initio calculations show that the SWSNTs are locally stable in vacuum and have zero band gap, suggesting that the SWSNTs are possibly metals rather than wide-gap semiconductors.

Abstract
In our study, we observed the clinical manifestations of 15 tetramethylenedisulfotetramine (TEM) toxicosis emergency patients diagnosed by plasma toxin chemical analysis, and evaluated the effect of emergency treatments. All cases could not be differentiated from the other kinds of toxicosis by clinical manifestations, and toxin chemical analysis was the sole definite diagnosis method. The effect of gastric lavage in early stage was especially obvious, 13 cases with convulsions got immediate relief after plasma exchange, the use of large dosage of tranquilizer resulted in better control on convulsion in 4 cases treated with ventilator than that in the others. Gastric lavage and chemical toxin analysis in early stage are of vital importance, plasma exchange, tracheotomy and mechanical ventilation are the most effective reatment methods.
