In this paper, we prove the existence of at least one positive solution pair (u, v)∈ H1(RN) × H1(RN) to the following semilinear elliptic system {-△u+u=f(x,v),x∈RN,-△u+u=g(x,v),x∈RN (0.1),by us... In this paper, we prove the existence of at least one positive solution pair (u, v)∈ H1(RN) × H1(RN) to the following semilinear elliptic system {-△u+u=f(x,v),x∈RN,-△u+u=g(x,v),x∈RN (0.1),by using a linking theorem and the concentration-compactness principle. The main conditions we imposed on the nonnegative functions f, g ∈C0(RN× R1) are that, f(x, t) and g(x, t) are superlinear at t = 0 as well as at t =+∞, that f and g are subcritical in t and satisfy a kind of monotonic conditions. We mention that we do not assume that f or g satisfies the Ambrosetti-Rabinowitz condition as usual. Our main result can be viewed as an extension to a recent result of Miyagaki and Souto [J. Diff. Equ. 245(2008), 3628-3638] concerning the existence of a positive solution to the semilinear elliptic boundary value problem {-△u+u=f(x,u),x∈Ω,u∈H0^1(Ω) where Ω ∩→RN is bounded and a result of Li and Yang [G. Li and J. Yang: Communications in P.D.E. Vol. 29(2004) Nos.5& 6.pp.925-954, 2004] concerning (0.1) when f and g are asymptotically linear. 展开更多

AIM:To investigate the clinical significance of hepatic blood inflow occlusion without hemihepatic artery control (BIOwHAC) in the treatment of hepatocellular carcinoma (HCC).METHODS:Fifty-nine patients with HCC were divided into 3 groups based on the technique used for achieving hepatic vascular occlusion:group 1,vascular occlusion was achieved by the Pringle maneuver (n=20);group 2,by hemihepatic vascular occlusion (HVO) (n=20);and group 3,by BIOwHAC (n=19).We compared the procedures among the three groups in term of operation time,intraoperative bleeding,postoperative liver function,postoperative complications,and length of hospital stay.RESULTS:There were no statistically significant differences (P > 0.05) in age,sex,pathological diagnosis,preoperative Child's disease grade,hepatic function,and tumor size among the three groups.No intraoperative complications or deaths occurrred,and there were no significant intergroup differences (P > 0.05) in intraoperative bleeding,hepatic function change 3 and 7 d after operation,the incidence of complications,and length of hospital stay.BIOwHAC and Pringle maneuver required a significantly shorter operation time than HVO;the difference in the serum alanine aminotransferase or aspartate aminotransferase levels before and 1 d after operation was more significant in the BIOwHAC and HVO groups than in the Pringle maneuver group (P < 0.05).CONCLUSION:BIOwHAC is convenient and safe;this technique causes slight hepatic ischemia-reperfusion injury similar to HVO. 展开更多

AIM To compare the operation time, blood loss, and early outcomes of acetabular components with and without the screw.METHODS Thirty patients who underwent cementless acetabular component with or without screw and whose follow-up exceeded one year period in total hip arthroplasty were evaluated. A posterior approach was used in all surgical procedures by one experienced surgeon. Demographic data, operation time, intra-and postoperative blood loss volume, follow-up clinical score, cup migration, and osteolysis were recorded. The Kolmogorov-Smirnov test was performed for testing the normality of study data. Mann-Whitney U test was used to analyze the intergroup differences. A P-value of ≤ 0.05 was considered statistically significant.RESULTS Acetabular components were used in 16(53.3%) patients with screw and 14(46.7%) without screw. After one year of follow-up, an osteolytic lesion of 3 mm was found in only one patient in the screw group. No cup migrationwas encountered. Intra-group mean Harris hip score significantly increased, but there was no significant intergroup difference. While the mean operation time of the screw group was 121.8 min(range; 95-140), it was 102.7 min(range; 80-120) in the no-screw group, and this difference was statistically significant(P = 0.002). The mean intraoperative/postoperative, and total blood loss were 556.6 mL(range: 350-800)/423.3 mL(range: 250-600), and 983.3 mL(range: 600-1350), respectively in the screw group; and 527 mL(range: 400-700)/456 mL(range: 230-600), and 983 mL(range: 630-1250), respectively in the no-screw group. The blood loss difference between the two groups was not significant. In the screw group, the operation time was 19.1 min longer than the no-screw group, and this difference was statistically significant.CONCLUSION Acetabular components with or without screw have similar results, but the use of screw increases the operation time significantly, while not changing the blood loss volume. 展开更多

Objectives To identify the loci involved in nonsyndromic cleft lip with or without cleft palate (NSCL/P) in Northern Chinese people in Shenyang by using genomewide and interaction linkage scan.Methods Two multiplex families in Shenyang from North China were ascertained through probands with NSCL/P.Blood of every member was drawn for DNA extraction and analysis.Genotypes were available for 382 autosomal short tandem repeat (STR) markers from the ABI Prism Linkage Mapping Set version 2.5.Linkage between markers and NSCL/P was assessed by 2-point parametric LOD scores,multipoint heterogeneity parametric LOD scores (HLODs),and multipoint nonparametric linkage score (NPL).Results The initial scan suggested linkage on Chromosomes 1,2,and 15.In subsequent fine mapping,1q32-q42 showed a maximum multipoint LOD score of 1.9(empirical P=0.013) and an NPL score of 2.35 (empirical P=0.053).For 2p24-p25,the multipoint NPL increased to 2.94 (empirical P=0.007).2-locus interaction analysis obtained a maximum NPL score of 3.73 (P=0.00078) and a maximum LOD score of 3 for Chromosome 1 (at 221 cM) and Chromosome 2 (at 29 cM).Conclusion Both parametric and nonparametric linkage scores greatly increased over the initial linkage scores on 1q32-q42,suggesting a susceptibility locus in this region.Nonparametric linkage gave a strong evidence for a candidate region on chromosome 2p24-p25.The superiority of 2-locus linkage scores compared to single-locus scores gave additional evidence for linkage on 1q32-q42 and 2p24-p25,and suggested that certain genes in the two regions may contribute to NCSL/P risks with interaction. 展开更多

BACKGROUND: The clearance of propofol is very rapid, and its transformation takes place mainly in the liver. Some reports indicated extrahepatic clearance of the drug and that the lungs are the likely place where the process occurs. This study was undertaken to compare the plasma concentrations of propofol both in the pulmonary and radial arteries after constant infusion during the dissection, anhepatic and reperfusion phases of orthotopic liver transplantation (OLT) without veno-venous bypass, attempting to investigate extrahepatic clearance and to determine whether the human lungs take part in the elimination of propofol. METHODS: Fifteen patients undergoing OLT without veno-venous bypass were enrolled in the study, and propofol was infused via a forearm vein at a rate of 2 mg· kg-1·h-1. Blood samples were simultaneously collected from pulmonary and radial arteries at the end of the first hepatic portal dissection (T0), at the clamping of the portal vein (T1), 30, and 60 minutes after the beginning of the anhepatic phase (T2, T3), and 30, 60, and 120 minutes after the unclamping of the new liver (T4, T5, T6). Plasma propofol concentrations were measured using a reversed- phase, high-performance liquid chromatographic method with fluorescence detection. RESULTS: The concentrations of plasma propofol in the pulmonary and radial arteries at T2 and T3 rose significantly compared with T0 and T1 (P<0.01) respectively. After reperfusion, the drug concentrations at T4, T5 and T6 decreased significantly compared with T2, T3 (P<0.01)respectively. There were no significant differences in plasma propofol concentrations between the pulmonary and radial arteries at any time points. CONCLUSIONS: Propofol is eliminated mainly by the liver, and also by extrahepatic organs. The lungs seem to be not a major site contributing to the extrahepatic metabolism of propofol in humans. 展开更多

Introduction:?Worldwide increasing cesarean section rates are expected to have a parallel increase in the number of cases of Placenta Previa with all the expected complications, including pathologically adherent placenta. This morbidly adherent placenta constitutes a serious and possibly a life threatening complication. An efficient team capable for managing possible complicated situations will be able to reduce mortality and morbidity. Objectives: The aim of our study was to evaluate maternal outcome in cases of Placenta Previa with and without morbidly adherent placenta. Methods: Analysis of all pregnancies complicated by antepartum hemorrhage during the period from January 2013 to September 2017 at King Abdul-Aziz University Hospital (KAUH), Jeddah, Kingdom of Saudi Arabia (KSA) was done. Cases of Placenta Previa with gestational age > 28 weeks were included. They were classified into 2 groups;Group (A) included Placenta Previa cases without morbidly adherent placenta and Group (B) included cases with morbidly adherent placenta. Maternal outcomes were recorded. Results: Placenta Previa was the leading cause of antepartum hemorrhage constituting 76.8%, out of them 52% were unbooked. Morbidly adherent placenta constituted 13.5% of total Placenta Previa cases and was diagnosed prenatally in only 1 case. Morbidity rate in placenta previa patients with adherent placenta (Group B) was higher than in placenta previa without adherent placenta (Group A). We considered the occurrence of intrapartum hypovolemic shock, Intensive care unit admission, surgical complications and peripartum hysterectomy as parameters for morbidity. P value for hypovolemic shock was insignificant (P = 0.580), significant for Intensive care unit admission (P = 0.008), significant for surgical complications (P = 0.009) and significant for peripartum 展开更多

It has been shown that a volume discharge is forming in non-uniform electric-field rough cathode and even anode without pre-ionization in SF6 and C2H6 mixtures. The discharge is presented with many diffuse channels attached to bright circular cathode spots that diverge towards the anode, with the channels overlapping, form a spatially uniform glow discharge. Self-Initiated Volume Discharge(SIVD) has been performed at a total mixture pressure up to 8 kPa and energy deposition up to 200 J/L. The experimental results indicate that Self-Sustained Volume Discharge(SSVD) in SF6 and C2H6 mixtures develops in the form of SIVD, which is promising for creation of high energy and pulse-periodic HF laser. 展开更多

However, the... Active power filter (APF) using novel virtual line-flux-linkage oriented control strategy can not only realizes no phase-locked-loop (PLL) control, but also achieves a good inhibitory effect to interfere. However, there are some problems in the conventional method, such as the error of amplitude, the shift of phase angle and the non-determinacy of initial oriented angle. In this paper, two one-order low-pass filters are adopted instead of the pure integrator in the virtual line-flux-linkage observer, which can steady the phase and amplitude. Furthermore, an original scheme of harmonics detection under the rotating coordinate is advanced based on the simplified space vector pulse width modulation (SVPWM) strategy. Meanwhile, by using the new SVPWM algorithm, the voltage space vector diagram of the three-level inverter can be simplified and applied into that of two-level inverter, and this makes the control for Neutral Point potential easier. 展开更多

BACKGROUND Retroperitoneal lymph node dissection(RPLND)plays a diagnostic,therapeutic,and prognostic role in myriad urologic malignancies,including testicular carcinoma,renal cell carcinoma(RCC),and upper urinary tract urothelial carcinoma.RCC represents 2%of all cancers with approximately 25%of patients presenting with advanced disease.Clear cell RCC(CCRCC)is the most common RCC,accounting for 75%-80%of all RCC.CASE SUMMARY A 71-year-old man presented with a history of benign prostatic hypertrophy.He was asymptomatic without any hematuria,pain,or other urinary symptoms.A computed tomography(CT)scan of the abdomen and pelvis showed a 1.8 cm left retroperitoneal lymph node.There was no evidence of renal pathology.A core biopsy was performed of the left para-aortic lymph node.Although the primary tumor site was unknown,the morphological and immunohistochemical features were most consistent with CCRCC.A RPLND was performed which revealed a single mass 5.5 cm in greatest dimension with extensive necrosis.The retroperitoneal lymph node was most compatible with CCRCC.A nephrectomy was not conducted as a renal mass had not been detected on any prior imaging studies.The patient did not receive any type of adjuvant therapy.The patient underwent surveillance with serial CT scans with contrast of the chest,abdomen,and pelvis for the next 5 years,all of which demonstrated no recurrent or metastatic disease and no evidence of retroperitoneal adenopathy.CONCLUSION Our unique case emphasizes the therapeutic role of metastasectomy in metastatic CCRCC even in the absence of primary tumor in the kidneys. 展开更多

This paper numerically demonstrates synchronization and bidirectional communication without delay line by using two semiconductor lasers with strong mutual injection in a face-to-face configuration. These results show that both of the two lasers' outputs synchronize with their input chaotic carriers. In addition, simulations demonstrate that this kind of synchronization can be used to realize bidirectional communications without delay line. Further studies indicate that within a small deviation in message amplitudes of two sides (±6%), the message can be extracted with signal-noise-ratio more than 10 dB; and the signal-noise-ratio is extremely sensitive to the message rates mismatch of two sides, which may be used as a key of bidirectional communication. 展开更多

A solid ternary mixture consisting of NaF, silicon and one of the metal oxides such as Al2O3, MgO, CaO, SrO, BaO was prepared and used as a defluorinated reagent for CF4 decomposition. The results show that the initial conversion of CF4 reached 100% over NaF-Si-MgO and NaF-Si-CaO at 850°C, and the reagent with NaF/Si/MgO molar ratio of 33/34/33 exhibited a high reactivity with a full conversion of CF4 lasting for 57 min.

This paper investigates asymptotic bounded consensus tracking(ABCT) of double-integrator multi-agent systems(MASs) with an asymptotically-unbounded-acceleration and bounded-jerk target(AUABJT) available to partial agents based on sampled-data without velocity measurements. A sampled-data consensus tracking protocol(CTP) without velocity measurements is proposed to guarantee that double-integrator MASs track an AUABJT available to only partial agents.The eigenvalue analysis method together with the augmented matrix method is used to obtain the necessary and sufficient conditions for ABCT. A numerical example is provided to illustrate the effectiveness of theoretical results. 展开更多

Global aphasia without hemiparesis is a striking stroke syndrome involving language impairment without the typically manifested contralateral hemiparesis, which is usually seen in patients with global aphasia following large left perisylvian lesions. The objective of this study is to elucidate the specific areas for lesion localization of global aphasia without hemiparesis by retrospectively studying the brain magnetic resonance images of six patients with global aphasia without hemiparesis to define global aphasia without hemiparesis-related stroke lesions before overlapping the images to visualize the most overlapped area. Talairach coordinates for the most overlapped areas were converted to corresponding anatomical regions. Lesions where the images of more than three patients overlapped were considered significant. The overlapped global aphasia without hemiparesis related stroke lesions of six patients revealed that the significantly involved anatomi- cal lesions were as follows: frontal lobe, sub-gyral, sub-lobar, extra-nuclear, corpus callosum, and inferior frontal gyrus, while caudate, claustrum, middle frontal gyrus, limbic lobe, temporal lobe, superior temporal gyrus, uncus, anterior cingulate, parahippocampal, amygdala, and subcallosal gyrus were seen less significantly involved. This study is the first to demonstrate the heterogeneous anatomical involvement in global aphasia without hemiparesis by overlapping of the brain magnetic resonance images. 展开更多

It is shown that in a Doppler broadened open N-type four-level atomic system with spontaneously generated coherence (SGC), the gain without inversion (GWI) is very sensitive to the variation of the relative phase between the probe field and the driving field; the atomic exit rate (R0) and the ratio (S) of the atomic injection rates have a considerable modulation effect on the phase-dependent GWI. GWI first increases and then decreases with R0 increasing; in a certain value range of S, GWI increases monotonically with S increasing; by adjusting the values of R0 and S, in an open system a much larger GWI can be obtained than in the corresponding closed system [2011 Phys. Rev. A 83 043805]. The modulation effects of R0 and S on the phase-dependent GWI in the case with the counter-propagating probe and driving fields are stronger than those in the co-propagating case, GWI in the co-propagating case is much larger than that in the counter-propagating case. 展开更多
