The cores regulation of paraffin-chitosan phase change microcapsules for constant temperature building.

Phase change materials (PCMs) can store and release latent heat under the designed phased change temperature and have received substantial interest for energy conservation and thermal control purposes. The use of PCMs in the construction of constant temperature buildings can improve the comfortable environment and save more energy. However, the leakage of PCMs during phase change process limits the application of PCMs. In this paper, a series of PCMs microcapsules with controllable core numbers is synthesized with paraffin (37 ℃) as the core and cross-linked chitosan as the wall. The single-core phase-change microcapsules (S-PCM) and multicore phase-change microcapsules (M-PCM) were prepared by adjusting the preparation condition. The latent heat of S-PCM and M-PCM are 61.4 mJ mg-1 and 50.1 mJ mg-1, respectively. The S-PCM and M-PCM display good stability without paraffin leakage. In addition, the composite blocks of gypsum and S-PCM (GSCM) and M-PCM (GMCM) were prepared and the thermoregulatory effection was investigated, where the surface temperature of GSCM was 5-10 ℃ lower than that of pure gypsum block. PCMs may also have broad application space in electronics, cold chain, and other industries.

TGFB1I1 promotes cell proliferation and migration in urothelial carcinoma.

Urothelial carcinoma (UC) is common cancer worldwide with a high prevalence in Taiwan, especially in the upper urinary tract, including the renal pelvis and ureter, also classifying as upper urinary tract urothelial carcinoma. Here, we aim to find a representative prognostic marker that strongly correlates to this type of carcinoma. Transforming growth factor beta-1-induced transcript 1 (TGFB1I1) is a cofactor of cellular TGF-ß1 and interacts with various nuclear receptors. The previous study showed that TGFB1I1 promotes focal adhesion formation, contributing to the epithelial-mesenchymal transition (EMT) with actin cytoskeleton and vimentin through TGFB1I1 regulation. We aim to reveal the role of TGFB1I1 in the tumorigenesis of UC. In silico and clinicopathological data of upper urinary tract urothelial carcinoma (UTUC) and urinary bladder urothelial carcinoma (UBUC) were accessed and analyzed for IHC staining regarding tumor characteristics, including survival outcome. Finally, an in vitro study was performed to demonstrate the biological changes of UC cells. In UTUC, overexpression of TGFB1I1 was significantly correlated with advanced tumor stage, papillary configuration, and frequent mitosis. Meanwhile, overexpression of TGFB1I1 was significantly correlated with advanced tumor stage and histological grade in UBUC. Moreover, the in vitro study shows that TGFB1I1 affects cell proliferation, viability, migration and wound healing. The EMT markers also decreased upon TGFB1I1 knockdown. In this study, we identified that TGFB1I1 regulates UC cell proliferation and viability and induces the EMT to facilitate cell migration in vitro, leading to its essential role in promoting tumor aggressiveness in both UTUC and UBUC.

Pineocytoma with malignant transformation to pineal parenchymal tumor with intermediate differentiation and leptomeningeal dissemination after subtotal tumor resection and adjuvant radiotherapy.

Pineocytoma is a rare tumor. It is rare for pineocytoma to present as leptomeningeal metastasis. We present a rare case of pineocytoma with malignant transformation and leptomeningeal metastasis after subtotal tumor resection and adjuvant radiotherapy. This case was a 58-year-old male with an unsteady gait for 2 months. Enhanced brain magnetic resonance imaging revealed a heterogeneous mass involving the pineal region. The initial pathological diagnosis of pineocytoma was confirmed after subtotal tumor resection. Two years after adjuvant radiotherapy to the primary site, the magnetic resonance imaging showed C2 and T2 metastatic lesions, with the final pathological diagnosis being pineal parenchymal tumor (PPT) with intermediate differentiation after the removal of T2 intramedullary tumor. After that adjuvant radiotherapy at the cervical and thoracic spinal cord was completed. There was no recurrence of the tumor 1 year after the radiotherapy. We report a rare case of pineocytoma with malignant transformation to PPT with intermediate differentiation and leptomeningeal dissemination.

Epstein-Barr Virus-Associated Smooth Muscle Tumor and Its Correlation With CD4 Levels in a Patient With HIV Infection.

Epstein-Barr virus-associated smooth muscle tumor (EBV-SMT) is a rare tumor found in immunocompromised patients, and its treatment is not well-established. A role for antiretroviral therapy in human immunodeficiency virus (HIV)-related EBV-SMT has been proposed; however, the relevance of tumor size, CD4 levels, and immune reconstitution inflammatory syndrome (IRIS) has not been previously reported. We present the first case, to our knowledge, of a tumor that shrank in association with elevated CD4 counts. IRIS occurred in this case following antiretroviral therapy. This finding highlights the importance of the immune response in HIV-related EBV-SMT.

The global warming potential of straw-return can be reduced by application of straw-decomposing microbial inoculants and biochar in rice-wheat production systems.

Straw-return methods that neither negatively impact yield nor bring environmental risk are ideal patterns. To attain this goal, it is necessary to conduct field observation to evaluate the environmental influence of different straw-return methods. Therefore, we conducted a 2-year field study in 2015-2017 to investigate the emissions of methane (CH4) and nitrous oxide (N2O) and the changes in topsoil (0-20 cm) organic carbon (SOC) density in a typical Chinese rice-wheat rotation in the Eastern China. These measurements allowed a complete greenhouse gas accounting (net GWP and GHGI) of five treatments including: FP (no straw, plus fertilizer), FS (wheat straw plus fertilizer), FB (straw-derived biochar plus fertilizer), FSDI (wheat straw with straw-decomposing microbial inoculants plus fertilizer) and CK (control: no straw, no fertilizer). Average annual SOC sequestration rates were estimated to be 0.20, 0.97, 1.97 and 1.87 t C ha-1 yr-1 (0-20 cm) for the FP, FS, FB and FSDI treatments respectively. Relative to the FP treatment, the FS and FSDI treatments increased CH4 emissions by 12.4 and 17.9% respectively, but decreased N2O emissions by 19.1 and 26.6%. Conversely, the FB treatment decreased CH4 emission by 7.2% and increased N2O emission by 10.9% compared to FP. FB increased grain yield, but FS and FSDI did not. Compared to the net GWP (11.6 t CO2-eq ha-1 yr-1) and GHGI (1.20 kg CO2-eq kg-1 grain) of FP, the FS, FB and FSDI treatments reduced net GWP by 12.6, 59.9 and 34.6% and GHGI by 10.5, 65.8 and 37.7% respectively. In rice-wheat systems of eastern China, the environmentally beneficial effects of returning wheat straw can be greatly enhanced by application of straw-decomposing microbial inoculants or by applying straw-derived biochar.

The combined effects of nitrogen fertilizer, humic acid, and gypsum on yield-scaled greenhouse gas emissions from a coastal saline rice field.

In coastal saline rice fields, rice production shows high greenhouse gas (GHG) emissions but low nitrogen use efficiency (NUE). However, few studies have focused on the combined effects of nitrogen (N) fertilizer and soil ameliorants on GHG emissions. Thus, a field experiment was conducted to study the combined effects of N fertilizer, humic acid, and gypsum on the global warming potential (GWP), yield-scaled greenhouse gas intensity (GHGI), rice grain yield, and NUE in coastal saline rice fields in southeastern China. The experiment was conducted with eight treatments: N0, N1, N0H1, N1H1, N0G1, N1G1, N0H1G1, and N1H1G1. The codes N0, N1, H1, and G1 represented treatments without N (0 kg N ha-1), with N (300 kg N ha-1), with humic acid (0.6 t ha-1), and with gypsum (0.6 t ha-1), respectively. Compared with the treatments without N addition, the application of N fertilizer significantly increased N2O emissions and grain yield by 41.9~130.6% and 32.8~57.5%, respectively, while significantly decreased the yield-scaled GHGI by 9.4~31.9%. Humic acid amendment significantly increased N2O emissions and grain yield as compared with the treatments without humic acid. Gypsum addition had no significant effects on CH4 and N2O emissions, GWP, yield-scaled GHGI, and grain yield in relation to the treatments without gypsum. In addition, compared with the N1 treatment, the N1H1, N1G1, and N1H1G1 treatments increased the grain yield by 18.3% (p < 0.05), 2.3%, and 10.4%, and decreased yield-scaled GHGI by 9.6%, 20.5%, and 31.2% (p < 0.05), despite similar GWPs, respectively. Overall, the N1H1 and N1H1G1 treatments are the appropriate fertilizer management to realize high yield together with low environmental impacts in coastal saline rice fields in China.

Linc00152 knockdown inactivates the Akt/mTOR and Notch1 pathways to exert its anti-hemangioma effect.

AIMS: Infantile hemangioma (IH) is one of the most common benign vascular tumors occurred in infants. Linc00152 is a kind of long non-coding RNAs (lncRNAs) and acts as a tumor oncogene. Recent study reported that Linc00152 is highly expressed in clinical IH tissues. However, the exact biological roles have not yet been investigated. The aim of the present study was to investigate the oncogenic roles of Linc00152 in IH and the underlying mechanism in vitro. MAIN METHODS: The expressions of Linc00152 in IH tissues and hemangioma-derived endothelial cells (HemECs) were determined using quantitative real time-PCR (qRT-PCR) analysis. The expressions of Akt/mTOR and Notch1 pathways related proteins were detected using western blot analysis. Cell proliferation was assessed by detecting Ki67 expression and CCK-8 assay. Cell apoptosis was evaluated by detecting apoptotic rate, caspase-3/7 activity, and Bcl-2 and Bax expression. KEY FINDINGS: The results demonstrated Linc00152 was up-regulated in clinical IH tissues and HemECs. Knockdown of Linc00152 in HemECs suppressed the activation of Akt/mTOR and Notch1 signaling pathways and caused reduction in cell proliferation and Ki67 expression in HemECs. Besides, Linc00152 knockdown resulted in a significant increase in apoptotic rate, caspase-3/7 activity, and Bax expression level, as well as a decrease in Bcl-2 expression level. However, the effects of Linc00152 knockdown on cell proliferation and apoptosis were mitigated by overexpression of Akt or Notch1. SIGNIFICANCE: Knockdown of Linc00152 suppressed HemECs proliferation and induced apoptosis via inhibiting Akt/mTOR and Notch1 signaling pathways.

Effects of different composting strategies on methane, nitrous oxide, and carbon dioxide emissions and nutrient loss during small-scale anaerobic composting.

Composting is considered as one of the main sustainable methods for the treatment of livestock manure. In this study we investigated the effects of additives (urea and rice straw) on methane (CH4), nitrous oxide (N2O), and carbon dioxide (CO2) emissions using a traditional Chinese pig slurry composting method over an 81-day period, as well as examining total organic carbon and total nitrogen loss. Four common treatment strategies were examined in this study: a control (MC), urea nitrogen addition (MN), composting using rice straw cover (MScover), and compost mixed with rice straw (MSmix). Our results indicate that the addition of urea resulted in the lowest total CH4 emissions and the highest N2O emissions. MScover treatment had the highest and most significant effect on CH4 emissions, while MSmix treatment had the lowest CO2 emissions. Carbon lost through CH4 and CO2 released during the experiment was 0.1-0.9 and 2.4-3.9% of total carbon loss, respectively, and nitrogen lost through N2O release was 11.1-17.9% of total nitrogen. In general, although MSmix, MScover, and MN treatments increased global warming potential by 21.4, 41.6, and 50.9% per kg of pig slurry, respectively, no statistical differences between the four treatments were recorded. By considering carbon and nitrogen conservation, as well as the improvement of the quality of compost and the mitigation of greenhouse gases (GHGs), the small-scale composting method of pig slurry alone is an acceptable environmentally friendly strategy for use in China.

Retrospective study on the outcomes of infantile tufted angioma complicated by Kasabach-Merritt Phenomenon.

OBJECTIVE: To analyze the clinical characteristics and treatment of pediatric tufted angiomas(TA)complicated by Kasabach-Merritt Phenomenon (KMP). METHOD: A retrospective analysis was conducted on the clinical data and follow-up data of 13 patients diagnosed with TA complicated by KMP. Five male and 8 female patients with an average age of 5.7 months (range, 29 days to 1 year) were treated with surgery between January 2009 and June 2012. According to the size and location of lesions and the degree of thrombocytopenia, complete or subtotal resection was performed. The median follow-up period was 3.4 years (range, 1.7 years to 5.2 years). Therapeutic outcomes were evaluated by platelet count and lesion size. RESULTS: Curative treatment of KMP is defined as restoration of normal hemostasis and elimination of tumor cells. Twelve patients achieved curative treatment and one died of multiple organ failure after operation. Ten patients received complete resection and three patients received incomplete resection. Thrombocyte count, hemoglobin and blood coagulation were respectively restored to normal levels within 1-3 days and 1-2 weeks post complete resection operation. One of the three patients who received subtotal resection operation died. In the other two patients, the platelet count fluctuated over time but remained above 60 × 109 /L, a significantly higher level than the preoperational level. Residual lesions slowly disappeared after continuous medication 3-6 months post operation. CONCLUSION: Early surgical treatment of patients with TA complicated with KMP resulted in significantly higher curative rate and reduced side-effects of drugs.

A comparison of methane and nitrous oxide emissions from inland mixed-fish and crab aquaculture ponds.

Inland aquaculture ponds in China collectively cover 2.57 million ha, so emissions of the greenhouse gases methane (CH4) and nitrous oxide (N2O) from these ponds may constitute a significant contribution to global warming. During 2016 and 2017, CH4 and N2O fluxes and a range of pond-water and sediment properties were measured in replicated (n = 4) "mixed-fish" and "crab" aquaculture ponds in southeast China. Annual CH4 and N2O emissions were 64.4 kg C ha-1 and 2.99 kg N ha-1, respectively, from the "mixed-fish" ponds, and 51.6 kg C ha-1 and 3.32 kg N ha-1, respectively, from the "crab" ponds. Emission differences between pond types were significant (p < 0.05) for both gases. CH4 fluxes from the "crab" ponds were significantly increased by the presence of aquatic vegetation, but N2O fluxes were not affected. Emissions of N2O were estimated to be 0.54% and 0.71% of the total nitrogen input (in the feed) for the "mixed-fish" and "crab" ponds, respectively. The net economic benefit-scaled sustained-flux global warming potential (NEB-scaled SGWP) of the "crab" ponds was 61.6% higher (p < 0.05) than that of the "mixed-fish" pond. Our CH4 and N2O emissions results suggest that aquaculture ponds can be important contributors to regional and national GHG inventories, with aquaculture type an important factor in total GHG impact. Further CH4 and N2O flux research is needed at aquaculture ponds across China to better establish the range of potential GHG impacts, and to confirm the importance of the influencing factors identified in this study.

Modeling the impact of crop rotation with legume on nitrous oxide emissions from rain-fed agricultural systems in Australia under alternative future climate scenarios.

Limited information exists on potential impacts of climate change on nitrous oxide (N2O) emissions by including N2-fixing legumes in crop rotations from rain-fed cropping systems. Data from two 3-yr crop rotations in northern NSW, Australia, viz. chickpea-wheat-barley (CpWB) and canola-wheat-barley (CaWB), were used to gain an insight on the role of legumes in mitigation of N2O emissions. High-frequency N2O fluxes measured with an automated system of static chambers were utilized to test the applicability of Denitrification and Decomposition model. The DNDC model was run using the on-site observed weather, soil and farming management conditions as well as the representative concentration pathways adopted by the Intergovernmental Panel on Climate Change in its Fifth Assessment Report. The DNDC model captured the cumulative N2O emissions with variations falling within the deviation ranges of observations (0.88±0.31kgNha-1rotation-1 for CpWB, 1.44±0.02kgNha-1rotation-1 for CaWB). The DNDC model can be used to predict between modeled and measured N2O flux values for CpWB (n=390, RSR=0.45) and CaWB (n=390, RSR=0.51). Long-term (80-yr) simulations were conducted with RCP 4.5 representing a global greenhouse gas stabilization scenario, as well RCP 8.5 representing a very high greenhouse gas emission scenario based on RCP scenarios. Compared with the baseline scenarios for CpWB and CaWB, the long-term simulation results under RCP scenarios showed that, (1) N2O emissions would increase by 35-44% for CpWB and 72-76% for CaWB under two climate scenarios; (2) grain yields would increase by 9% and 18% under RCP 4.5, and 2% and 14% under RCP 8.5 for CpWB and CaWB, respectively; and (3) yield-scaled N2O-N emission would increase by 24-42% for CpWB and 46-54% for CaWB under climate scenarios, respectively. Our results suggest that 25% of the yield-scaled N2O-N emission would be saved by switching to a legume rotation under climate change conditions.

Nitrogen fertilizer in combination with an ameliorant mitigated yield-scaled greenhouse gas emissions from a coastal saline rice field in southeastern China.

Coastal saline rice fields play an increasingly important role in rice production and associated greenhouse gas (GHG) emissions. However, few studies investigated the influences of nitrogen (N) fertilizer and soil ameliorant on GHG emissions simultaneously in this region. Thus, a field experiment was established to study the effects of different N fertilizers and soil ameliorant on global warming potential (GWP) and yield-scaled GHG intensity (GHGI) after accounting for carbon dioxide (CO2) equivalent emissions of methane (CH4) and nitrous oxide (N2O), agrochemical inputs, and farm operations along with agronomic nitrogen use efficiency (NUE) during the rice season of 2016 in a coastal saline paddy in Lianyungang, China. The experiment was initiated with four N treatments (N0, no N; Nu, urea; Nm, organic-inorganic mixed fertilizer; Nw, organic fertilizer made from wheat straw) and two ameliorant (A) treatments (A0, no ameliorant; A1, 22.5 kg ha-1 ameliorant). The results showed that three N fertilizers significantly increased the CH4 emissions, N2O emissions, GWP, and grain yield by 42.2% (p < 0.001), 57.1% (p < 0.001), 49.8% (p < 0.001), and 58.9% (p < 0.001), respectively. NuA1, NmA1, and NwA1 treatments obviously reduced the yield-scaled GHGI by 21.3%, 16.3%, and 12.4%, respectively, relative to the corresponding NuA0, NmA0, and NwA0 treatments. Overall, although three N fertilizers would increase the GWP, combining an ameliorant amendment with N fertilizer can effectively reduce the yield-scaled GHGI and meanwhile increase the grain yield, particularly the NmA1 strategy.

Year-round atmospheric wet and dry deposition of nitrogen and phosphorus on water and land surfaces in Nanjing, China.

The dry deposition of ammonium, nitrate, and total phosphorus (TP) to both water (DW) and land (DD) surfaces, along with wet deposition, were simultaneously monitored from March 2009 to February 2011 in Nanjing, China. Results showed that wet deposition of total phosphorus was 1.1 kg phosphorus ha (-1)yr(-1), and inorganic nitrogen was 28.7 kg nitrogen ha (-1)yr(-1), with 43% being ammonium nitrogen. Dry deposition of ammonium, nitrate, and total phosphorus, measured by the DW/DD method, was 7.5/2.2 kg nitrogen ha (-1)yr(-1), 6.3/ 4.9 kg nitrogen ha (-1)yr(-1), and 1.9/0.4 kg phosphorus ha (-1)yr(-1), respectively. Significant differences between the DW and DD methods indicated that both methods should be employed simultaneously when analyzing deposition to aquatic and terrestrial ecosystems in watershed areas. The dry deposition of ammonium, nitrate, and total phosphorus contributed 38%, 28%, and 63%, respectively, to the total deposition in the simulated aquatic ecosystem; this has significance for the field of water eutrophication control.

[Management of Kasabach-Merritt syndrome by drug therapy and surgery].

OBJECTIVE: To summarize the characters of Kasabach-Merritt syndrome (KMS) and to evaluate the therapeutic effect of drug therapy combined with surgery. METHODS: From 2004 to 2010, 59 cases with KMS, who underwent drug therapy and surgery, were retrospectively studied. The average age of the patients, including 33 male and 26 female (male/female, 1.269/1), was 2.9 months (range, 7 days-2.5 years). 28 cases with maxillofacial lesions were treated with the ligation of external carotid artery and injection of carbonyldiamide and methylprednisolone. 31 cases with lesions at trunks and extremities were treated by excision of lesions. All the patients were followed up for 2.8 years (range, 6.5 months -7.3 years). Therapeutic outcomes were assessed by evaluating platelet counts,size of lesion, function of trunk and limb. RESULTS: 58 cases were cured except for one dead case. Emergency operation was given in 4 cases, and selective operation was performed in other cases (55 cases). The thrombocyte count, hemoglobin and blood coagulation function returned to normal within 1-2 weeks. The mental condition, appetite, body weight,sleeping were greatly improved one week after treatment. The size of the lesions decreased gradually after the management of ligation of external carotid artery including 18 cases within 6-12 months and 10 cases within 13-24 months. Long term follow-up studies indicated that there was no recurrent case, and the weight, height, immunity of the patients with good function activities were in keeping with the normal counterparts. CONCLUSIONS: The drug combined with surgery therapy is a very reliable management with high curative rate, short disease period and minimum side-effect.
