[A Comparative Study of Soil Environmental Standards for Agricultural Land Among Different Countries and Its Implication for China].

Soil environmental quality of agricultural land plays a determinate role in the quality of agricultural products, human health, and the safety of the ecosystem. In 2018, China issued the "soil environment quality risk control standard for soil contamination of agriculture land" (GB 15618-2018), which has been essential to soil pollution prevention and the control of agricultural land. In this study, a systematic and comparative analysis of soil environmental standards for the agricultural land of 17 countries or regions was conducted, including the framework, protection objective, derivation method, contaminant elements, analyses methods, and standard values, as well as the impact factors.

[Characteristics of Microplastic Present in Urban Road Dust].

Microplastics (MPs), as an emerging contaminant, have attracted wide attention due to their potentially negative impact on the ecosystem. However, information on microplastic pollution in terrestrial environments, especially road dust, is still rare. In this study, the microplastic pollution in road dust from the Yushan District of Ma'anshan City was characterized.

Effects of different frequencies of repetitive transcranial magnetic stimulation in stroke patients with non-fluent aphasia: a randomized, sham-controlled study.

Objective: The purpose of this study was to compare the efficacy of repetitive transcranial magnetic stimulation (rTMS) applied at different frequencies to the contra-lesional hemisphere to optimize the treatment of post-stroke non-fluent aphasia.

Method: Patients with post-stroke non-fluent aphasia were divided randomly into four groups: a high-frequency rTMS (HF-rTMS) group (10 Hz), a low-frequency rTMS (LF-rTMS) group (1 Hz), a sham stimulation group, and a control group. All groups received the standard treatment (consisting of drug therapy, conventional physical exercises, and speech training); in the HF-rTMS and LF-rTMS, this was supplemented with magnetic stimulation that targeted the mirror area within the right hemispheric Broca's area.

Lung involvement in primary Sjögren's syndrome: Correlation between high-resolution computed tomography score and mortality.

Background: Lung involvement is one of the major systemic manifestations of primary Sjögren's syndrome (pSS). This study aims to demonstrate the correlation between high-resolution computed tomography (HRCT), pulmonary function test (PFT) results, and outcome in these patients.

Methods: Forty-four pSS patients were enrolled and their PFT results and HRCT findings/scores were retrospectively investigated.

Frequency and risk factors associated with atherosclerotic plaques in patients with a zero coronary artery calcium score.

Background: Analysis of the coronary artery calcium levels usually provides important information that can be used in patient prognosis and stratification of treatment when coronary artery disease is suspected. However, plaques, with or without significant stenosis, have been reported in patients without coronary artery calcium. The aim of this study was to determine the frequency and risk factors of the development of coronary artery plaques in individuals with a zero calcium score.

Selection of arterial input function for postprocessing of cerebral ct perfusion in chronic unilateral high-grade stenosis or occlusion of the carotid or middle cerebral artery.

Rationale And Objectives: We evaluated the effect of the arterial input function (AIF) on computed tomography perfusion (CTP) in patients with unilateral high-grade stenosis or occlusion in the carotid artery or middle cerebral artery without acute stroke.

Materials And Methods: CTP datasets were retrospectively postprocessed using the same venous output function and different AIF selections: the second segment of the anterior cerebral artery (A2 AIF), the second segment of the middle cerebral artery (MCA) on the lesion side (affected M2 AIF), and M2 on the contralateral side (nonaffected M2 AIF). We measured CTP values in the region of interest (ROI) in the bilateral MCA territory and evaluated the lesion-to-contralateral ratios.

Myocardial bridging in Taiwanese: noninvasive assessment by 64-detector row coronary computed tomographic angiography.

Background: Myocardial bridging (MB) is a congenital structural variant in which a segment of the epicardial coronary artery tunnels into and is surrounded by the myocardium. MB has been correlated to some clinical complications of cardiovascular disease (CVD). The depiction rate of MB varies significantly between catheter coronary angiography and autopsy studies.

[Orthotopic T pouch ileal neobladder: evaluations of urodynamics and upper urinary tract functions].

Objective: To evaluate the urodynamics and functions of upper urinary tract in a substitute of orthotopic T pouch ileal bladder.

Methods: From June 2004 through September 2009, 90 patients underwent the construction of an orthotopic T pouch ileal neobladder after radical cystectomy for muscle-invasive bladder cancer. The radiographic or ultrasound evaluation of upper urinary tract, determination of renal functions and urodynamic evaluation of T pouch ileal neobladder were performed by data analysis.

Myocardial bridging in Taiwan: depiction by multidetector computed tomography coronary angiography.

Background/purpose: Myocardial bridging (MB) is a condition in which a segment of the major epicardial coronary artery is tunneled within and surrounded by the myocardium. This condition has been linked to severe complications. The aim of this study was to evaluate the incidence of MB in Taiwanese subjects examined with electrocardiogram-gated, 16-slice, multidetector computed tomography (MDCT) coronary angiography, as well as to determine the location, depth, and length of the bridged segments and the concomitant atherosclerosis of MB.

Expressional induction of Paralichthys olivaceus cathepsin B gene in response to virus, poly I:C and lipopolysaccharide.

Cathepsin B is a lysosomal cysteine protease of the papain-like enzyme family with multiple biological functions. In this study, Paralichthys olivaceus cathepsin B (PoCatB) cDNA was isolated from flounder embryonic cells (FEC) treated with UV-inactivated grass carp hemorrhage virus (GCHV) and subsequently identified as a virally induced gene. The full length cDNA of PoCatB is 1801bp encoding 330-amino acids.

MRI of alveolar soft-part sarcoma.

Alveolar soft-part sarcoma (ASPS) is rare. We present a case of a 30-year-old woman with a 6-month history of a palpable mass in her left thigh. MRI showed an 8-cm mass and a satellite nodule at the left gluteus muscle.

The innate immune response to grass carp hemorrhagic virus (GCHV) in cultured Carassius auratus blastulae (CAB) cells.

Virus infection of mammalian cells activates an innate antiviral immune response characterized by production of interferon (IFN) and the subsequent transcriptional upregulation of IFN-stimulated genes (ISGs) by the JAK-STAT signaling pathway. Here, we report that a fish cell line, crucian carp (Carassius auratus L.) blastulae embryonic (CAB) cells, can produce IFN activity and then form an antiviral state after infection with UV-inactivated grass carp hemorrhagic virus (GCHV), a double-stranded (ds) RNA virus.

Molecular cloning and stress-induced expression of paralichthys olivaceus heme-regulated initiation factor 2alpha kinase.

The heme-regulated initiation factor 2alpha kinase (HRI) is acknowledged to play an important role in translational shutoff in reticulocytes in response to various cellular stresses. In this study, we report its homologous cDNA cloning and characterization from cultured flounder embryonic cells (FEC) after treatment with UV-inactivated grass carp haemorrhagic virus (GCHV). The full-length cDNA of Paralichthys olivaceus HRI homologue (PoHRI) has 2391 bp and encodes a protein of 651 amino acids.

Inductive expression and characterization analysis of Paralichthys olivaceus pigment epithelium-derived factor in a virally infected cell line.

Pigment epithelium-derived factor (PEDF) is acknowledged to be a non-inhibitory member of the serine protease inhibitor (serpin) superfamily, with antiangiogenesis, and neuroprotective and immunoregulatory function, mainly in the tissues of nervous system. Here, A PEDF gene homolog, Paralichthys olivaceus PEDF (PoPEDF), was isolated from flounder embryonic cells (FEC) treated with UV-inactivated Grass carp hemorrhage virus (GCHV) and subsequently identified as a differentially expressed gene. The full length of PoPEDF cDNA is 1803bp with an open reading frame of 1212bp encoding a 403-amino-acid protein.
