Abstract
Citrus melanose, caused by the ascomycete fungus Diaporthe citri, is one of the most important diseases in China that affects not only the production but also the quality of citrus. In China, mancozeb is recommended to control melanose disease at the dose of 1.34 g/liter. However, it is widely applied in practice at the dose of 2.66 g/liter or even 4 g/liter, because reduced efficacy of the recommended dose was observed in regions severely damaged by melanose. In this study, some ecofriendly chemicals for melanose management were evaluated. First, the sensitivity to fungicides was screened in the laboratory based on the inhibition of mycelial growth and conidial germination of D. citri. Results showed that both quinone outside inhibitor (QoI) fungicides kresoxim-methyl and trifloxystrobin inhibited conidial germination of D. citri up to 100% at 0.1 μg/ml. The in vivo control efficacy on detached fruit indicated that treatments with elastic nanocopolymer film at 2 g/liter, mancozeb at 1 g/liter, and kresoxim-methyl at 0.1 g/liter significantly inhibited the infection process compared with the control treatment of mineral oil alone. In field trials, the efficacy of kresoxim-methyl at 0.1 g/liter and elastic nanocopolymer film at 2 g/liter mixed with mancozeb at 1 g/liter was equal to that of mancozeb at 2.66 g/liter. The use of mancozeb could be reduced greatly, and the newly developed fungicide combinations are more environmentally friendly due to the low toxicity of both QoI fungicides and elastic nanocopolymer film. The newly developed method with ecofriendly chemicals should play an important role in the management of citrus melanose in the future.

Abstract
In holographic displays, the Gerchberg-Saxton (GS) method has been widely used to generate the phase-only hologram (POH). However, as the constraint strategy of the GS method cannot optimize the POH well enough, the display quality is degraded. Various methods have been proposed to solve this problem, such as introducing the dummy area, using an initial quadratic phase, and modifying the amplitude constraint strategy. This paper proposes a simple and effective iterative method to optimize POH for the high-quality reconstructed image, which is a combination of the above three methods. In the proposed method, the target image is padded with zeros, and the padded image is divided into the target and non-target region. The initial phase in the target region is reset to the quadratic phase, and the optimized parameters α and β are introduced to modify the amplitude constraint strategy. In the iterative process, this strategy is applied to the target region. Numerical and optical experiments were conducted to verify the effectiveness of the proposed method. The results show that the speckle noise is effectively suppressed, and the quality of the reconstructed image is improved.

Abstract
The brain is among the most energetically costly organs in the vertebrate body, while the size of the brain varies within species. The expensive-tissue hypothesis (ETH) predicts that increasing the size of another costly organ, such as the gut, should compensate for the cost of a small brain. Here, the ETH was tested by analyzing the relationship between brain size variation and digestive tract length in a Swelled-vented frog (Feirana quadranus). A total of 125 individuals across 10 populations ranging from 586 to 1,702 m a.s.l. from the Qinling-Daba Mountains were sampled. With the increase in altitude, the brain size decreases and the digestive tract length increases. Different brain regions do not change their relative size in a consistent manner. The sizes of telencephalon and cerebellum decrease with the increase in altitude, while the olfactory nerve increases its size at high altitudes. However, the olfactory bulb and optic tectum have no significant relationship with altitude. After controlling for snout-vent length (SVL), a significant negative correlation could be found between brain size and digestive tract length in F. quadranus. Therefore, the intraspecific variation of brain size follows the general patterns of ETH in this species. The results suggest that annual mean temperature and annual precipitation are environmental factors influencing the adaptive evolution of brain size and digestive tract length. This study also suggests that food composition, activity times, and habitat complexity are the potential reasons driving the adaptive evolution of brain size and digestive tract length.

Abstract
BACKGROUND The objective of this study was to compare the efficacy of lateral and bilateral percutaneous vertebroplasty (PVP) in treating osteoporotic vertebral compression fractures (OVCFs). METHODS A comprehensive literature search was performed using PubMed, Cochrane Library, EMBASE, CMB, CNKI, Wanfang, and VIP databases between January 2014 and December 2020. The clinical efficacy of the 2 approaches was evaluated by comparing perioperative outcomes (operation time, X-ray exposure time, volume of injected cement), clinical outcomes (degree of vertebral height restoration, improvement of Cobb angle, visual analogue scale score, and Oswestry Disability Index scores), and operation-related complications (rate of cement leakage, adjacent vertebral fracture rate, and nerve root stimulation). Data were analyzed using RevMan 5.3.3 and Stata 15.1. RESULTS A total of 237 related articles were retrieved, and 17 randomized controlled trials were included. Meta-analysis results showed that compared to bilateral PVP, unilateral PVP led to decreased operation times (mean difference [MD] = -15.24, 95% confidence interval [CI]: [-17.77, -12.70], P < .05), decreased X-ray exposure time (MD-8.94, 95% CI[-12.08,-5.80]; P < .01), decreased volumes of injected cement (MD-1.57, 95% CI[-2.00,-1.14]; P < .05), and lower incidence of cement leakage (risk ratio [RR] = 0.6,95% CL[0.48,0.77], P < .01). Patients that underwent unilateral PVP experienced more effective pain relief at the last follow-up (MD-0.09, 95% CI [-0.15,-0.03];P=.006 < .05) and had a low degree of vertebral height restoration (MD-0.38, 95% CL [-0.71, -0.06]; P=.02 < .05). However, no differences in adjacent vertebral fractures (RR 1.19, 95% CI [0.78,1.82]; P = .41 > .01), nerve root stimulation (RR 1.98, 95% CI [0.22, 17.90]; P = .54 > .01), improvement of Cobb angle (MD = -0.18, 95% CI [-0.49, 0.13], P = .26 > .01), and improvement of ODI score (MD = 0.22, 95% CI[-0.37, 0.80], P > .05) were found between the 2 approaches. CONCLUSIONS Although both unilateral and bilateral PVP can improve the quality of life of this patient population by managing pain effectively, unilateral PVP offers more benefits, including shorter operation time and less fluoroscopy, and should be recommended in clinical practice for OVCFs.

Abstract
CONTEXT Glycogen storage diseases are rare. Increased glycogen in the liver results in increased attenuation. OBJECTIVE Investigate the association and function of a noncoding region associated with liver attenuation but not histologic nonalcoholic fatty liver disease. DESIGN Genetics of Obesity-associated Liver Disease Consortium. SETTING Population-based. MAIN OUTCOME Computed tomography measured liver attenuation. RESULTS Carriers of rs4841132-A (frequency 2%-19%) do not show increased hepatic steatosis; they have increased liver attenuation indicative of increased glycogen deposition. rs4841132 falls in a noncoding RNA LOC157273 ~190 kb upstream of PPP1R3B. We demonstrate that rs4841132-A increases PPP1R3B through a cis genetic effect. Using CRISPR/Cas9 we engineered a 105-bp deletion including rs4841132-A in human hepatocarcinoma cells that increases PPP1R3B, decreases LOC157273, and increases glycogen perfectly mirroring the human disease. Overexpression of PPP1R3B or knockdown of LOC157273 increased glycogen but did not result in decreased LOC157273 or increased PPP1R3B, respectively, suggesting that the effects may not all occur via affecting RNA levels. Based on electronic health record (EHR) data, rs4841132-A associates with all components of the metabolic syndrome (MetS). However, rs4841132-A associated with decreased low-density lipoprotein (LDL) cholesterol and risk for myocardial infarction (MI). A metabolic signature for rs4841132-A includes increased glycine, lactate, triglycerides, and decreased acetoacetate and beta-hydroxybutyrate. CONCLUSIONS These results show that rs4841132-A promotes a hepatic glycogen storage disease by increasing PPP1R3B and decreasing LOC157273. rs4841132-A promotes glycogen accumulation and development of MetS but lowers LDL cholesterol and risk for MI. These results suggest that elevated hepatic glycogen is one cause of MetS that does not invariably promote MI.

Abstract
Determining the insertion position of an exogenous gene in the target plant genome is one of the main issues in the transgenic plant field. This study introduced a simple, rapid, and accurate method to clone the flanking sequences of the transgenic bar gene as the anchoring gene in the transgenic maize genome using single-primer polymerase chain reaction (PCR). This method was based on the distribution of restriction sites in the maize genome and adopted the single-primer PCR method. Cloning the flanking sequences with the restriction site-anchored single-primer PCR simplified the experimental procedures by about 70% and reduced the experimental time by more than 80%. In conclusion, the restriction site-anchored single-primer PCR was a simple, rapid method to obtain the unknown flanking sequences in the transgenic plants.

Abstract
Here, we compare the molecular mechanism of soybean heterosis through the differential expression of basic cloning. Specifically, we cloned 22 differentially expressed cDNA fragments from hybrid combinations of Jilin 38 x EXP (which had obvious yield advantages) and their parents. In addition, we compared the homology of these fragments and predicted their functions. Cloning differentially expressed genes included the identification of the calmodulin binding protein, 18S ribosomal gene, 26S ribosomal gene, soybean satellite DNA, soybean acid phosphatase, soybean chlorophyll a/b-binding protein II (Cab-6) gene, soybean chloroplast PI 437654 gene, soybean PPR protein gene, and other fragments with unknown functions. In conclusion, the cloning and functional prediction of differentially expressed soybean genes in this study is anticipated to provide valuable information for studies on the molecular mechanism of heterosis.

Abstract
With recent advances in sequencing, genotyping arrays, and imputation, GWAS now aim to identify associations with rare and uncommon genetic variants. Here, we describe and evaluate a class of statistics, generalized score statistics (GSS), that can test for an association between a group of genetic variants and a phenotype. GSS are a simple weighted sum of single-variant statistics and their cross-products. We show that the majority of statistics currently used to detect associations with rare variants are equivalent to choosing a specific set of weights within this framework. We then evaluate the power of various weighting schemes as a function of variant characteristics, such as MAF, the proportion associated with the phenotype, and the direction of effect. Ultimately, we find that two classical tests are robust and powerful, but details are provided as to when other GSS may perform favorably. The software package CRaVe is available at our website (http://dceg.cancer.gov/bb/tools/crave).

Abstract
The etiology of concurrent stenoses of extracranial and intracranial vessels in patients with ischemic stroke is poorly understood, but hereditary factors are believed to be important. We aimed to determine whether genetic polymorphisms affecting homocysteine and lipid metabolism are associated with concurrent stenoses. The genotypes of 191 Han Chinese patients with acute ischemic stroke, of whom 47 (25%) had concurrent stenoses, and 167 healthy control patients in Hong Kong were examined for the following polymorphisms: paraoxonase 1 (PON1) Q192R, methylenetetrahydrofolate reductase (MTHFR) A222V, glutamate-cysteine ligase catalytic-subunit (GCLC)-129C>T, and oxidized low-density lipoprotein receptor (OLR) 3' untranslated region C>T (rs1050283). The genotype distributions of PON1 Q192R and MTHFR A222V, which affect lipid and homocysteine metabolism, differed significantly between patients with stroke and healthy controls. The presence of at least one R allele in PON1 Q192R and a TT allele in OLR rs1050283 were associated with concurrent stenoses. We also identified a possible association between the presence of at least one V allele in MTHFR A222V and concurrent stenoses. This study shows that genetic polymorphisms affecting homocysteine and lipid metabolism are possible risk factors for stroke and concurrent stenoses.

Abstract
PURPOSE To determine the long-term outcome of ischemic stroke patients with concurrent intracranial and extracranial atherosclerosis using magnetic resonance angiography. METHODS A prospective cohort of patients in Hong Kong with acute ischemic stroke was studied with magnetic resonance angiography of the brain and carotid duplex. All patients were followed up regularly for the development of recurrent stroke, cardiac events, or death. RESULTS Totally 343 patients with acute ischemic stroke were included, of whom 104 (30%) had concurrent intracranial and extracranial lesions. The follow-up period was up to 76 months (mean 44.5 months). Overall, 55 patients (15.5%) died of any cause and 91 patients (26.5%) suffered a further nonfatal vascular event. The overall 5-year cumulative rates of mortality, restroke and poor outcomes (combined death and further vascular events) were 18, 27 and 37%, respectively. In patients with concurrent lesions, these rates were 31, 41 and 51%, respectively. The corresponding rates were 13, 22 and 31% in patients without concurrent lesions. The risks were highest in the first year after stroke. More deaths (log rank, 16.3; p = 0.0001), restrokes (log rank, 9.71; p = 0.002) and poor outcomes (log rank, 13.87; p = 0.0001) were found among patients with concurrent lesions. The presence of concurrent vascular lesions, advanced age, smoking, hyperlipidemia and previous history of stroke were independent predictors of poor outcomes. CONCLUSIONS The long-term prognosis of ischemic stroke patients with concurrent atherosclerosis of intracranial and extracranial vessels is poor. They are at high risk of further vascular events or death.

Abstract
Copper ferrite nano-particles with Fe/Cu ratios varying from 2 to 12 were successfully synthesized by combustion process using copper nitrate, iron nitrate and urea. The resultant powders were investigated by scanning electron microscopy (SEM), vibrating sample magnetometer (VSM). The results revealed that the copper ferrite powders are uniform in the range of 250-300 nm. The copper ferrite with Fe/Cu ratio of 2 possessed a saturation magnetization of 5.47 emu/g, and an intrinsic coercive force of 241.98 Oe, with Fe/Cu ratio of 12 possessed a saturation magnetization of 22.06 emu/g and an intrinsic coercive force of 247.94 Oe. Moreover, these copper ferrite magnetic nano-particles also acted as catalyst for the oxidation of 2,3,6-trimethylphenol to synthesize 2,3,5-trimethylhydrogenquinone and 2,3,5-trimethyl-1,4-benzoquinone for the first time. The conversion of 2,3,6-trimethylphenol in the kinetic behavior of oxidation was investigated in detail. The reaction shows dramatically enhanced by the addition of copper-ferrite nano-particles to the solution.

Abstract
Radiation-induced peripheral nerve tumor, in particular a benign entity such as a neurofibroma, is rare, with only a few cases being reported so far. We demonstrate a case of radiation-induced neurofibromata along the left cervical nerve roots in a man with a background of localized targeted hypofractionated radiation therapy as adjuvant treatment for left cervical nodal metastasis complicating nasopharyngeal carcinoma. The toxicity of high-dose radiation in a hypofractionated regime is also stressed.

Abstract
RhoA and its downstream target Rho kinase regulate serum response factor (SRF)-dependent skeletal and smooth muscle gene expression. We previously reported that long-term serum deprivation reduces transcription of smooth muscle contractile apparatus encoding genes, by redistributing SRF out of the nucleus. Because serum components stimulate RhoA activity, these observations suggest the hypothesis that the RhoA/Rho kinase pathway regulates SRF-dependent smooth muscle gene transcription in part by controlling SRF subcellular localization. Our present results support this hypothesis: cotransfection of cultured airway myocytes with a plasmid expressing constitutively active RhoAV14 selectively enhanced transcription from the SM22 and smooth muscle myosin heavy chain promoters and from a purely SRF-dependent promoter, but had no effect on transcription from the MSV-LTR promoter or from an AP2-dependent promoter. Conversely, inhibition of the RhoA/Rho kinase pathway by cotransfection with a plasmid expressing dominant negative RhoAN19, by cotransfection with a plasmid expressing Clostridial C3 toxin, or by incubation with the Rho kinase inhibitor, Y-27632, all selectively reduced SRF-dependent smooth muscle promoter activity. Furthermore, treatment with Y-27632 selectively reduced binding of SRF from nuclear extracts to its consensus DNA target, selectively reduced nuclear SRF protein content, and partially redistributed SRF from nucleus to cytoplasm, as revealed by quantitative immunocytochemistry. Treatment of cultured airway myocytes with latrunculin B, which reduces actin polymerization, also caused partial redistribution of SRF into the cytoplasm. Together, these results demonstrate for the first time that the RhoA/Rho kinase pathway controls smooth muscle gene transcription in differentiated smooth muscle cells, in part by regulating the subcellular localization of SRF. It is conceivable that the RhoA/Rho kinase pathway influences SRF localization through its effect on actin polymerization dynamics.

Abstract
We have isolated and characterized the human m3 muscarinic receptor gene and its promoter. Using 5' rapid amplification of cDNA ends (RACE), internal polymerase chain reaction (PCR), and homology searching to identify EST clones, we determined that the cDNA encoding the m3 receptor comprises 4,559 bp in 8 exons, which are alternatively spliced to exclude exons 2, 4, 6, and/or 7; the receptor coding sequence occurs within exon 8. Analysis of P1 artificial chromosome (PAC) and bacterial artificial chromosome (BAC) clones and of PCR- amplified genomic DNA, and homology searching of human chromosome 1 sequence provided from the Sanger Centre (Hinxton, Cambridge, UK) revealed that the m3 muscarinic receptor gene spans at least 285 kb. A promoter fragment containing bp -1240 to +101 (relative to the most 5' transcription start site) exhibited considerable transcriptional activity during transient transfection in cultured subconfluent, serum-fed canine tracheal myocytes, and 5' deletion analysis of promoter function revealed the presence of positive transcriptional regulatory elements between bp -526 and -269. Sequence analysis disclosed three potential AP-2 binding sites in this region; five more AP-2 consensus binding motifs occur between bp -269 and +101. Cotransfection with a plasmid expressing human AP-2alpha substantially increased transcription from m3 receptor promoter constructs containing 526 or 269 bp of 5' flanking DNA. Furthermore, m3 receptor promoter activity was enhanced by long-term serum deprivation of canine tracheal myocytes, a treatment that is known to increase AP-2 transcription-promoting activity in these cells. Together, these data suggest that expression of the human m3 muscarinic receptor gene is regulated in part by AP-2 in airway smooth muscle.

Abstract
An efficient and rapid gene transformation system of rice mediated by Agrobacterium tumefaciens was used. Calli induced from immature and mature embryos of Zhonghua No. 11, a japonic rice variety, were cultured with the A. tumefaciens strain EHA105 harboring the superbinary plasmid pDsBar1300 or pUBITs separately, and more than 400 independent transgenic lines inserted Ds element or Ac fragment were obtained. Some visible mutants in T0 or T1 generation were found, consisting of disease resistance, albino, dwarf, male sterile, chlorosis, early heading, late heading, stripe, etc. From the phenotype analysis, a few mutants such as dwarf and male sterile seemed to be linked to the Basta resistance and the transposon.

Abstract
Abstract
MHC (called HLA in man) class II genes play an essential role in cell-mediated immunity. Absence of HLA class II Ag on B lymphocytes is the basis of some congenital immunodeficiencies (CID). We have studied CID by generating transient heterokaryons from cell lines of such patients, and we report that the mutations fall into four complementation groups. In addition, fusions with the HLA class II deletion mutant 721.180 indicate that the genetic defects for each group in HLA class II expression map outside the HLA class II region. A small HLA-DRA promoter fragment is sufficient to drive expression of a reporter gene in normal B cell lines, but expression from the same construct is clearly reduced in mutant cell lines representative of all four complementation groups. This confirms earlier results that indicate defective transcription of HLA class II genes in the class II- CID mutant cell lines. Analysis of proteins that bind to the DRA promoter in nuclear extracts of the mutants suggests that complexes recognizing distinct elements of the DRA promoter may be quantitatively decreased in different mutants. In addition, we show that nuclear extracts from two groups fail to transcribe a DRA promoter construct in vitro accurately reflecting their DRA- phenotypes. In contrast, nuclear extracts from another mutant, RJ2.2.5, transcribe the DRA construct, albeit at a reduced level. Finally, though cell lines from different groups complement each other in vivo, no complementation was observed by mixing extracts for transcription in vitro.

Abstract
Forty-two surgical patients were given epidural tramadol for control of postoperative pain. They were randomly assigned to three groups: group 1 (n = 15), in which 25 mg of tramadol were given; group 2 (n = 13), in which 50 mg of tramadol were given; and group 3 (n = 14), in which 75 mg of tramadol were given. When the patients complained of wound pain, epidural tramadol was given. Heart rate, blood pressure, respiratory rate, oxygen saturation (SpO2), sedation scale, motor blockade, verbal rating scale, subjective grading, and visual analogue pain scale (VAPS) were measured and recorded before the tramadol administration, at 5 and 15 min, and at 1, 2, 4, and 8 h after the tramadol administration. Only 26.6% of the patients in group 1 had significant relief of pain. The rest of them needed at least one incremental dose of 25 mg of tramadol. The baseline VAPS of the patients in group 2 was 8.9 +/- 2.0. It became 5.46 +/- 3.0 (p greater than 0.05) 15 min after tramadol was given, and dropped further to 1.9 +/- 1.8 (p greater than 0.05) 2 h later. The average duration of pain relief was 12.0 +/- 5.9 h. In group 3, the initial VAPS was 8.14 +/- 1.9. It decreased to 4.28 +/- 1.8 (p greater than 0.05) 15 min, and further dropped to 1.7 +/- 0.9 (p greater than 0.05) 2 h following tramadol administration. The average duration of pain relief was 11.3 +/- 4.8 h. The common side effects of tramadol such as dizziness, nausea, and dry mouth, were most frequently found in group 3.(ABSTRACT TRUNCATED AT 250 WORDS)
