ABSTRACT

The study aims to explore an effective approach to improve the sensory quality and consumer satisfaction of cookies in the food industry. L. reuteri and L. rhamnosus were chosen to ferment egg yolk and their effects on dough properties and physicochemical properties, flavor, texture, color, and sensory acceptability of cookies were studied. Results show that the utilization of fermented egg yolk significantly decreased baking loss and increased spread factor of cookies. GC-MS analysis indicates different Lactobacillus species enhanced cookie flavor through unique mechanisms. Texture analysis shows cookies prepared with L. rhamnosus-fermented egg yolk had significantly lower hardness (1807.12 g) than control cookies (2028.34 g). Sensory evaluation reveals the L. reuteri-fermented egg yolk significantly improved the overall acceptability of cookies by enhancing appearance, flavor, and mouthfeel scores. These findings have practical implications for food manufacturers seeking to enhance their product's quality and appeal, thereby gaining a competitive edge in the market.

ABSTRACT

With the construction and development of modern and smart cities, people's lives are becoming more intelligent and diversified. Surveillance systems increasingly play an active role in target tracking, vehicle identification, traffic management, etc. In the 6G network environment, facing the massive and large-scale data information in the monitoring system, it is difficult for the ordinary processing platform to meet this computing demand. This paper provides a data governance solution based on a 6G environment. The shortcomings of critical technologies in wireless sensor networks are addressed through ZigBee energy optimization to address the shortage of energy supply and high energy consumption in the practical application of wireless sensor networks. At the same time, this improved routing algorithm is combined with embedded cloud computing to optimize the monitoring system and achieve efficient data processing. The ZigBee-optimized wireless sensor network consumes less energy in practice and also increases the service life of the network, as proven by research and experiments. This optimized data monitoring system ensures data security and reliability.

ABSTRACT

This study firstly quantified the responses of seeds of Zostera marina to different planting times (22 September, 5 October, 23 October, 7 November and 20 November in 2015) through a field seed-planting experiment over a two year period. The suitable seed planting time required by the seeds of Z. marina was evaluated. The seedling establishment rate of Z. marina subjected to different planting times ranged from 7% to 55%, with the higher values attained on the treatments of 22 September and 5 October. New plant patches from seed were fully developed and well maintained on the planting time of 22 September, 5 October and 23 October after 2 years following planting. The shoot density under the three treatments ranged from 62 shoots per replicate to 72 shoots per replicate with an average of 67 shoots per replicate in September 2017. According to the propagation assessment and growth analysis, we found that the planting time from mid-September to mid-October may be the optimal time to plant seeds of Z. marina in our experimental site. Our results demonstrate that seed planting time has an important effect on the effectiveness of eelgrass restoration and provide data that could prove helpful in the development of successful eelgrass restoration.

ABSTRACT

The potential anesthetic neurotoxicity on the neonate is an important focus of research investigation in the field of pediatric anesthesiology. It is essential to understand how these anesthetics may affect the development and growth of neonatal immature and vulnerable brains. Functional magnetic resonance imaging (fMRI) has suggested that using anesthetics result in reduced functional connectivity may consider as core sequence for the neurotoxicity and neurodegenerative changes in the developed brain. Anesthetics either directly impact the primary structures and functions of the brain or indirectly alter the hemodynamic parameters that contribute to cerebral blood flow (CBF) in neonatal patients. We hypothesis that anesthetic agents may either decrease the brain functional connectivity in neonatal patients or animals, which was observed by fMRI. This review will summarize the effect and mechanism of anesthesia on the rapid growth and development infant and neonate brain with fMRI through functional connectivity. It is possible to provide the new mechanism of neuronal injury induced by anesthetics and objective imaging evidence in animal developing brain.

ABSTRACT

Immune checkpoint inhibitors(ICIs) that activate tumor-specific immune responses bring new hope for the treatment of hepatocellular carcinoma(HCC). However, there are still some problems, such as uncertain curative effects and low objective response rates, which limit the curative effect of immunotherapy. Therefore, it is an urgent problem to guide the use of ICIs in HCC based on molecular typing. We downloaded the The Cancer Genome Atlas-Liver hepatocellular carcinoma(TCGA-LIHC) and Mongolian-LIHC cohort. Unsupervised clustering was applied to the highly variable data regarding expression of DNA damage repair(DDR). The CIBERSORT was used to evaluate the proportions of immune cells. The connectivity map(CMap) and pRRophetic algorithms were used to predict the drug sensitivity. There were significant differences in DDR molecular subclasses in HCC(DDR1 and DDR2), and DDR1 patients had low expression of DDR-related genes, while DDR2 patients had high expression of DDR-related genes. Of the patients who received traditional treatment, DDR2 patients had significantly worse overall survival(OS) than DDR1 patients. In contrast, of the patients who received ICIs, DDR2 patients had significantly prolonged OS compared with DDR1 patients. Of the patients who received traditional treatment, patients with high DDR scores had worse OS than those with low DDR scores. However, the survival of patients with high DDR scores after receiving ICIs was significantly higher than that of patients with low DDR scores. The DDR scores of patients in the DDR2 group were significantly higher than those of patients in the DDR1 group. The tumor microenvironment(TME) of DDR2 patients was highly infiltrated by activated immune cells, immune checkpoint molecules and proinflammatory molecules and antigen presentation-related molecules. In this study, HCC patients were divided into the DDR1 and DDR2 group. Moreover, DDR status may serve as a potential biomarker to predict opposite clinical prognosis immunotherapy and non-immunotherapy in HCC.

ABSTRACT

Aim: To compare the arthroscopy vs. arthrotomy for the treatment of native knee septic arthritis. Methods: Electronic databases of PubMed, Embase and Cochrane Library were searched for eligible studies. Retrospective comparative studies comparing arthroscopy or arthrotomy for patients with septic arthritis of the native knee were eligible for this review. The primary outcome was recurrence of infection after first procedure. The secondary outcomes included hospital length of stay, operative time, range of motion of the involved knee after surgery, overall complications and mortality rate, Results: Thirteen trials were included in this study. There were a total of 2,162 septic arthritis knees treated with arthroscopic debridement and irrigation, and 1,889 septic arthritis knees treated with open debridement and irrigation. Arthroscopy and arthrotomy management of the knee septic arthritis showed comparable rate of reinfection (OR = 0.85; 95% CI, 0.57-1.27; P = 0.44). No significant difference was observed in hospital length of stay, operative time and mortality rate between arthroscopy and arthrotomy management group, while arthroscopy treatment was associated with significantly higher knee range of motion and lower complication rate when compared with arthrotomy treatment. Conclusion: Arthroscopy and arthrotomy showed similar efficacy in infection eradication in the treatment of native septic knee. However, arthroscopy treatment was associated with better postoperative functional recovery and lower complication rate.

ABSTRACT

BACKGROUND: Liver cancer is one of the most common cancers worldwide. microRNAs (miRNAs) have been recognized as minimally invasive prognostic markers for distinct types of cancer. This study evaluates the mitigation role of miR-328-3p on liver cancer in vitro and in vivo. METHODS: Liver cancer cell line Huh-7 and HepG2 were used for in vitro experiments. Compared with the control group, miR-328-3p overexpression inhibited the proliferation, invasion, and promoted apoptosis of Huh-7 cells. miR-328-3p and endoplasmic reticulum metalloprotease 1 (ERMP1) had an excellent targeting relationship. Compared with the pcDNA-ERMP1 transfection group, the ratios of p-PI3K/PI3K, p-AKT/AKT, and p-mTOR/mTOR in miR-328-3p mimic and pcDNA-ERMP1 co-transfection group were significantly decreased. Animal models were set up using four-week-old immunodeficient BABL/c female nude mice. Huh-7 cells transfected with lentivirus holding miR-328-3p or empty vector were injected into the right dorsal side of BABL/c nude mice, respectively. Tumor volume was measured every five days. After one month, animals were sacrificed, xenograft tumors were dissected and weighed for RT-PCR and immunohistochemical assays. RESULTS: Compared with control group, miR-328-3p overexpression significantly inhibited tumor weight (0.46±0.07 vs. 0.11±0.05 g, P<0.05) and tumor volume (1876±321 vs. 543±168 mm3, P<0.05) after thirty days. miR-328-3p overexpression significantly downregulated the percentage of Ki67 positive cells, N-cadherin positive cells and vimentin positive cells. CONCLUSIONS: These findings suggested that miR-328-3p could be a new treatment or a novel marker for liver cancer prognosis.

ABSTRACT

The dynamics of photogenerated carriers and mobile ions in operational cesium lead halide (CsPbI3) perovskite solar cells (PSCs) under working conditions are studied using nanoscale-resolved fluorescence lifetime imaging microscopy (FLIM). The temporally and spatially resolved photoluminescence (PL) changes in the perovskite film during and after bias light soaking are dynamically monitored. Through the analysis of the dynamic variations of PL intensity and PL lifetime of an open-circuit PSC, the impacts of light soaking are revealed by a dynamic model of photogenerated charge carrier and mobile ions. We confirmed the different behaviors between morphological domain interiors and domain boundaries during light soaking, which shed light on the engineering of the domain interiors in addition to the commonly considered domain boundary strategies. This work provides a full picture of the photogenerated process in an operational PSC and therefore guides the design and operation of perovskite-based optoelectronic devices.

ABSTRACT

This paper provides deep understanding of the formation mechanism of perovskite film fabricated by sequential solution-based methods. It compares two sequential spin-coating methods for Cs0.15 (MA0.7 FA0.3 )0.85 PbI3 perovskite. First is the "static process," with a stoppage between the two spin-coating steps (1st PbI2 -CsI-dimethyl sulfoxide (DMSO)-dimethylformamide (DMF) and 2nd methylammonium iodide (MAI)-formamidinium iodide (FAI)-isopropyl alcohol). Second is the "dynamic process," where the 2nd precursor is dispensed while the substrate is still spinning from the 1st step. For the first time, such a dynamic process is used for Cs0.15 (MA0.7 FA0.3 )0.85 PbI3 perovskite. Characterizations reveal improved film formation with the dynamic process due to the "retainment" of DMSO-complex necessary for the intermediate phase which i) promotes intercalation between precursors and ii) slows down perovskite crystallization for full conversion. The comparison on as-deposited perovskite before annealing indicates a more ordered film using this dynamic process. This results in a thicker, more uniform film with higher degree of preferred crystal orientation and higher carrier lifetime after annealing. Therefore, dynamic-processed devices present better performance repeatability, achieving a higher average efficiency of 17.0% compared to static ones (15.0%). The new insights provided by this work are important for perovskite solar cells processed sequentially as the process has greater flexibility in resolving solvent incompatibility, allowing separate optimizations and allowing different deposition methods.

ABSTRACT

The study aimed to gain knowledge about low back pain (LBP) in nurses working in the orthopedic departments of tertiary hospitals in Sichuan province, China. We used a cross-sectional survey to examine the prevalence of LBP among 797 inpatient nurses who had worked for 1 year in an orthopedic department in one of 29 hospitals (Grade 3A) in Sichuan province. The survey included a questionnaire to determine the prevalence of LBP and factors related to LBP, a screening graph of LBP symptoms, the Roland Morris Disability Questionnaire (RMDQ), and the Fear Avoidance Beliefs Questionnaire (FABQ) for LBP. The 1-year period prevalence of LBP in the nursing population was 66.8% and the point prevalence was 51.3%. Among the 523 nurses who had experienced LBP, the mean total number of days that LBP had been experienced during the past year was 20.2 ± 16.3 days (range = 1-90 days). The annual number of episodes of LBP was 5.7 ± 4.5 times/year (range = 1-20 times/year). More than half the orthopedic nurses (51.1%) planned to quit, and 5.8% thought of leaving their job due to LBP. These study findings indicate that nurses in this region experience a burden of LBP similar to those in other regions in the world.

ABSTRACT

In the present study, the anti-inflammatory function of Phellinus linteus polysaccharide (PLP) was investigated in animal and cell inflammation models, and the anti-inflammatory mechanism of PLP was also explored. Sixty 8-week ICR mice were randomly divided into 3 groups, and DSS group and DSS + PLP group mice received 2.0% DSS and PLP was orally administered at 500 mg/kg/day. Our data showed that PLP administration obviously improved the health status of mice and inhibited DSS-induced pathological alterations and significantly reduced inflammatory cytokine expressions in the colonic tissues. In lipopolysaccharide-induced inflammation cell model, PLP supplement also significantly reduced inflammatory cytokine expressions and inhibited MAPK pathway as well as the translocations of NF-κB and AP-1. Meanwhile, PLP supplement regulated PPARα and PPARγ phosphorylation and blocked MAPK activation. Taken together, PLP exhibits anti-inflammatory function and its molecular mechanism may be involved in MAPK and PPAR signal pathways, which reduce the expressions of inflammatory cytokines.

ABSTRACT

Objectives Hepatic echinococcosis (HE) is a severe parasitic disease that occurs worldwide, and radical surgery is the recommended therapy. This study was performed to investigate the efficacy of using a transversus abdominis plane (TAP) block during surgery on postoperative pain and recovery of patients with HE under the guidelines of an enhanced recovery after surgery (ERAS) protocol. Methods Fifty-eight patients from the Tibetan plateau who underwent surgery for treatment of HE by the same surgeons under the guidance of ERAS were included in the present study. A TAP block was conducted before closing the abdominal cavity. Results The consumption of sufentanil was significantly lower in patients of the TAP than control group. Patients had a significantly shorter time to first flatus in the TAP than control group. Other parameters showed no significant differences between the two groups. Conclusions Use of the TAP block could reduce the consumption of analgesic medication and promote recovery of patients from the Tibetan plateau under the guidance of an ERAS protocol.

ABSTRACT

Segment 7 is considered an unfavorable portion for laparoscopic hepatectomy because of technical difficulties in exposure and controlling bleeding. We compared intermittent Pringle with continuous half-Pringle maneuver in laparoscopic liver resections of tumors in segment 7. A retrospective analysis was conducted in a total of 36 consecutive patients with tumors in segment 7 undergoing laparoscopic liver resections between July 2011 and February 2016 (16 in the Pringle group versus 20 in the half-Pringle group). The two groups were well matched in baseline characteristics. The operative time (274.5 ± 34.3 versus 237.6 ± 41.8 min), overall declamping time (28.4 ± 8.6 versus 2.3 ± 2.5 min), and ischemic duration (69.7 ± 16.5 versus 52.7 ± 13.2 min) were significantly longer in the Pringle group (P < 0.05). The amount of intraoperative blood loss (612.5 ± 222.3 versus 417.4 ± 163.8 mL) and transfusion (335.2 ± 58.7 versus 224.8 ± 76.2 mL) was significantly greater in the Pringle group (P < 0.05). The Pringle group was associated with significantly lower postoperative albumin and higher C-reactive protein levels on postoperative days 1, 3, and 7 (P < 0.05). Laparoscopic hepatectomy for tumors in segment 7 can be performed safely and effectively with successful exposure of surgical field and proper hepatic blood flow occlusion. Continuous half-Pringle maneuver offers the advantages of less operative time and blood loss, less injury, and better recovery.

ABSTRACT

BACKGROUND: Hepatic alveolar echinococcosis (HAE) is a severe and common parasitic disease in Tibetan Plateau of China. The infected patients have to move to plain areas to receive treatments due to the poor medical conditions in plateau areas. Our aim was to investigate the application of Enhanced Recovery after Surgery (ERAS) program in perioperative management for HAE patients from Tibet Plateau and the notes for patients with landform changes. MATERIAL AND METHODS: A total of 89 HAE patients from Tibet Plateau (altitude: average of 4500 m) prior received adaptive treatments at the cooperative hospital (altitude: 1500-2000 m) and accepted surgery at plain regions (altitude: 200-400 m). The patients in ERAS group received ERAS program care and patients in conventional management group received conventional care during perioperative period. RESULTS: Patients in ERAS group displayed significant shorter hospital stay and shorter time for recovery of gurgling compared with conventional management group (ERAS group versus conventional management group: 10.48 ± 3.525 d versus 20.29 ± 8.632 d; 1.56 ± 1.236 d versus 2.8 ± 1.19 d; all P < 0.01). The number of patients with complications of bloating, nausea/vomiting, pulmonary infection, urinary tract infection, upper gastrointestinal hemorrhage, and pulmonary edema was remarkably reduced (number, ERAS group versus conventional management group: 14 versus 24; 5 versus 16; 7 versus 24; 4 versus 13; 0 versus 10; all P < 0.05), and the visual analog scale scores in postoperative days 1 and 2 were obviously decreased in patients of ERAS group (score, ERAS group versus conventional management group: 2.5 ± 1.288 versus 3.83 ± 1.87; 2.25 ± 0.838 versus 3.51 ± 1.468; all P < 0.01). CONCLUSIONS: Patients from Tibet Plateau need to receive adaptive treatments for landform changes before receiving surgeries at plain regions. ERAS program is effective and safe for Tibetan HAE patients during perioperative period.

ABSTRACT

Here, we investigate photoluminescence (PL) and time-resolved photoluminescence (TRPL) in CH3NH3PbBr3 perovskite under continuous illumination, using optical and electro-optical techniques. Under continuous excitation at constant intensity, PL intensity and PL decay (carrier recombination) exhibit excitation intensity dependent reductions in the time scale of seconds to minutes. The enhanced nonradiative recombination is ascribed to light activated negative ions and their accumulation which exhibit a slow dynamics in a time scale of seconds to minutes. The observed result suggests that the organic-inorganic hybrid perovskite is a mixed electronic-ionic semiconductor. The key findings in this work suggest that ions are photoactivated or electro-activated and their accumulation at localized sites can result in a change of carrier dynamics. The findings are therefore useful for the understanding of instability of perovskite solar cells and shed light on the necessary strategies for performance improvement.

ABSTRACT

BACKGROUND: Despite accumulated experience and advancing techniques for laparoscopic hepatectomy, bleeding remains the major concern during parenchymal transection. The vascular inflow control technique is still important to decrease intraoperative blood loss. The objective of this study was to compare intermittent Pringle with continuous hemihepatic vascular inflow occlusion using extra-glissonian approach in laparoscopic liver resection. METHODS: Between January 2011 and January 2015, a total of 79 consecutive patients with tumors locating either in the right or in the left hemiliver were included into this retrospective study (45 in the Pringle group vs. 34 in the half-Pringle group). Preoperative clinical characteristics, intraoperative details, postoperative complications and outcomes of patients were compared. RESULTS: The two groups were well matched according to clinical characteristics, tumor features, types of liver resection and histopathology (P > 0.05). The mean operative time (247.5 ± 61.3 vs. 221.4 ± 48.7 min, P = 0.0446), ischemic duration (62.8 ± 28.3 vs. 44.1 ± 20.5 min, P = 0.0017) and overall declamping time (21.2 ± 8.2 vs. 0.9 ± 1.9 min, P < 0.05) were significantly longer in the Pringle group than in the half-Pringle group. The mean amount of intraoperative blood loss (568.2 ± 325.1 vs. 420.7 ± 307.2 mL, P = 0.0444) and transfusion (266.1 ± 123.4 vs. 203.2 ± 144.6 mL, P = 0.0406) were significantly greater in the Pringle group. The overall operative morbidity rate was significantly higher in the Pringle group (40 vs. 17.6%, P = 0.0324). The Pringle group was associated with significantly higher alanine aminotransferase and aspartate transaminase levels on postoperative day (POD) 7 and lower albumin levels on PODs 1 and 3 (P < 0.05). The C-reactive protein levels were significantly higher in the Pringle group than in the half-Pringle group on POD 1 (37.5 ± 21.4 vs. 28.2 ± 19.0 mg/L, P = 0.0484), POD 3 (114.0 ± 53.4 vs. 90.6 ± 47.9 mg/L, P = 0.0474) and POD 7 (54.9 ± 29.8 vs. 40.1 ± 26.4 mg/L, P = 0.0245). CONCLUSION: Continuous hemihepatic vascular inflow occlusion using extra-glissonian approach offers the advantages of less operative time and blood loss, less injury and better recovery in laparoscopic liver resection.

ABSTRACT

BACKGROUND: The high recurrence rate after hepatic resection in hepatocellular carcinoma (HCC) is a major obstacle to improving prognosis. The objective of the present study was to explore the function of genistein, a soy-derived isoflavone, in enhancing the inhibitory effect of cisplatin on HCC cell proliferation and on tumor recurrence and metastasis in nude mice after curative hepatectomy. METHODS: Proliferation of human HCC cells (HCCLM3) was detected by 3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide (MTT) assay. Synergistic effects of genistein and cisplatin were evaluated with the median-effect formula. Nude mice bearing human HCC xenografts underwent tumour resection (hepatectomy) 10 days post implantation, then received intraperitoneal administration of genistein or cisplatin alone or the combination of the two drugs. 33 days after surgery, recurrent tumours and pulmonary metastasis were evaluated individually. MMP-2 level in recurrent tumours was detected by immunohistochemistry and real-time PCR; MMP-2 expression in HCCLM3 was detected by immunocytochemistry. RESULTS: Genistein and cisplatin both suppressed the growth and proliferation of HCCLM3 cells. The two drugs exhibited synergistic effects even at relatively low concentrations. In vivo, mice in the combined genistein and cisplatin group had a smaller volume of liver recurrent tumors and fewer pulmonary metastatic foci compared with single drug treated groups. Cisplatin upregulated the expression of MMP-2 in both recurrent tumours and HCCLM3, while genistein abolished cisplatin-induced MMP-2 expression. CONCLUSIONS: Genistein reinforced the inhibitory effect of cisplatin on HCC cell proliferation and tumour recurrence and metastasis after curative hepatectomy in nude mice, possibly through mitigation of cisplatin-induced MMP-2 upregulation.

ABSTRACT

AIM: To evaluate the predictive value of preoperative predictors for portal vein thrombosis (PVT) after splenectomy with periesophagogastric devascularization. METHODS: In this prospective study, 69 continuous patients with portal hypertension caused by hepatitis B cirrhosis underwent splenectomy with periesophagogastric devascularization in West China Hospital of Sichuan University from January 2007 to August 2010. The portal vein flow velocity and the diameter of portal vein were measured by Doppler sonography. The hepatic congestion index and the ratio of velocity and diameter were calculated before operation. The prothrombin time (PT) and platelet (PLT) levels were measured before and after operation. The patients' spleens were weighed postoperatively. RESULTS: The diameter of portal vein was negatively correlated with the portal vein flow velocity (P < 0.05). Thirty-three cases (47.83%) suffered from postoperative PVT. There was no statistically significant difference in the Child-Pugh score, the spleen weights, the PT, or PLT levels between patients with PVT and without PVT. Receiver operating characteristic curves showed four variables (portal vein flow velocity, the ratio of velocity and diameter, hepatic congestion index and diameter of portal vein) could be used as preoperative predictors of postoperative portal vein thrombosis. The respective values of the area under the curve were 0.865, 0.893, 0.884 and 0.742, and the respective cut-off values (24.45 cm/s, 19.4333/s, 0.1138 cm/s(-1) and 13.5 mm) were of diagnostically efficient, generating sensitivity values of 87.9%, 93.9%, 87.9% and 81.8%, respectively, specificities of 75%, 77.8%, 86.1% and 63.9%, respectively. CONCLUSION: The ratio of velocity and diameter was the most accurate preoperative predictor of portal vein thrombosis after splenectomy with periesophagogastric devascularization in hepatitis B cirrhosis-related portal hypertension.

ABSTRACT

BACKGROUND/AIMS: The results of much research on the variation of the hepatic hemodynamic and functional hepatic reserve after splenectomy with periesophagogastric devascularization are very different, some are even converse. The purpose of this study is to observe the variation. METHODOLOGY: From July 2006 to August 2007, thirty patients with portal hypertension caused by hepatitis B cirrhosis underwent splenectomy with periesophagogastric devascularization in our medical group in West China Hospital of Sichuan University. The PVPG (portal venous pressure gradient) was measured by inductor continually during operation. Moreover, the HAF (hepatic artery flow), PVF (portal venous flow) and hepatic arterial RI (resistant index) were measured with Doppler sonography. The EHBF (effective hepatic blood flow) and ICGR15 (indocyanine green retention rate at 15 minutes) were obtained respectively by indocyanine green clearance test before and after the operation. The MELD (model for end stage liver disease) score was calculated at the same time. RESULTS: The four values of PVPG after laparotomy, ligating the splenic artery, splenectomy and periesophagogastric devascularization showed a tendency to decrease progressively. The PVF decreased and HAF increased in compensation after operation. The EHBF increased, and both the ICGR15 and the MELD score decreased postoperatively. CONCLUSIONS: After splenectomy with periesophagogastric devascularization, the functional hepatic reserve increases at least in the short term notwithstanding the PVPG and PVF decrease.
