Subintimal recanalization for non-acute occlusion of intracranial vertebral artery in an emergency endovascular procedure: A case report.

Background: Endovascular recanalization of non-acute intracranial artery occlusion is technically difficult, particularly when the microwire enters the subintima. Although the subintimal tracking and re-entry technique has been well established in the endovascular treatment of coronary artery occlusion, there is limited experience with its use in intracranial occlusion due to anatomical variations and a lack of dedicated devices.

Case Summary: A 74-year-old man was admitted to the hospital two days after experiencing acute weakness in both lower extremities, poor speech, and dizziness.

Objective: To explore the protective effects of live or pasteurized and Amuc_1100 protein on a rat model of diabetes mellitus induced by high-fat diet (HFD) combined with streptozotocin (STZ).

Methods: A total of 96 Sprague-Dawley (SD) rats were randomly assigned to 8 groups, including 6 experimental groups and 2 control groups, with 12 rats in each group. HFD combined with STZ injection was given to the rats to create a simulated model of the progression of diabetes mellitus type 2.

Objective: To investigate the effects of ( ) on the proliferation, apoptosis and insulin secretion of rat pancreatic islet cell tumor cells (INS-1).

Methods: INS-1 cells were divided into three groups, normal, repair, and protect groups, and subsequently every group was subjected with metabolites, live orpasteurized for 48 h. A group that did not treat with anything was set as blank control.

[Adsorption of Cr(Ⅵ) in Water by Maifanite Modified with Different LDHs Coatings].

Under alkaline conditions, the hydrothermal coprecipitation method was used to form different layered double hydroxides (LDHs) by combining different bivalent and trivalent metal compounds, such as ZnCl, MgCl, AlCl, and FeCl, and then LDHs were coated on the surface of the original maifanite. The effect of LDHs coating-modified maifanite on the improvement of Cr(Ⅵ) adsorption in water was studied using isothermal adsorption, desorption, non-isothermal adsorption, adsorption kinetics, pH, and competitive adsorption tests, respectively. The results show that the maximum theoretical adsorption capacity of modified maifanite for Cr(Ⅵ) is close to ten times that of original maifanite at 15℃.

[Influencing Factors for Phosphorus Removal by Modified Bio-ceramic Substrates Coated with ZnAl-LDHs Synthesized by Different Modification Conditions].

Under different pH conditions, the hydrothermal and co-precipitation method was used to synthesize layered double hydroxides (LDHs) coated on bio-ceramic substrates with three different Zn/Al molar ratios. Applying the original and six kinds of modified bio-ceramic substrates coated with ZnAl-LDHs (bio-ceramic/ZnAl-LDHs) in simulated vertical-flow constructed wetlands, experiments for phosphorus removal and isothermal adsorption were conducted to analyze the mechanism and effect of each synthesis factor. The results showed that ZnAl-LDHs (pH=11) had a more obvious effect on phosphorus removal, especially for bio-ceramic/ZnAl-LDHs (pH=11, 1:1), whose average removal rates of TP, TDP and SRP were enhanced over 70%.

[Purification Efficiency and Influencing Factors of Combined Bio-filters for Aquaculture Wastewater].

As an effective technology for wastewater treatment, bio-filter has been widely used. Nevertheless, there is still a lack of systematic report on purification efficiency and influencing factors of combined bio-filters. To this end, a novel combined system that consisted of aerated vertical-flow filter (AVF) followed by baffled horizontal-flow filter (BHF) was designed.

Diversity and Dynamics of Microbial Community Structure in Different Mangrove, Marine and Freshwater Sediments During Anaerobic Debromination of PBDEs.

Little is known about the diversity and succession of indigenous microbial community during debromination of polybrominated diphenyl ethers (PBDEs). This study examined the diversity and dynamics of microbial community structure in eight saline (mangrove and marine) and freshwater sediment microcosms exhibiting different debrominating capabilities for hexa-BDE 153, a common congener in sediments, using terminal restriction fragment length polymorphism (T-RFLP) and clone library analyses. The results showed that microbial community structure greatly differed between the saline and freshwater microcosms, likely leading to distinct variations in their debrominating capabilities and pathways.

[Effects of NO-N Loading on the Early-Period Efficiency of Denitrification and Carbon Releasing in Constructed Wetland Filled with Bark].

The reuse of tailwater as recycled water requires an advanced nitrogen removal treatment, during which carbon source is added based on the tailwater quality. This study conducted an advanced nitrogen removal model test in constructed wetland to evaluate the effects of influent NO-N loading on denitrification and carbon releasing. In the constructed wetland, bark was used as filler and carbon source for nitrogen removal.

[Mechanisms of Phosphorus Removal by Modified Zeolites Substrates Coated with Zn-LDHs in Laboratory-scale Vertical-flow Constructed Wetlands].

Zn-Layered double hydroxides (LDHs) were selected to carry out the experiment in present work based on the previous research results. According to the co-precipitation method, three kinds of different Zn-LDHs (FeZn-LDHs, CoZn-LDHs and AlZn-LDHs) were synthesized by ZnCl, FeCl, AlCl, and CoCl solution in alkaline conditions and Zn-LDHs were in-situ coated on the surface of natural zeolites. With the filling of the natural and three kinds of Zn-LDHs modified zeolites in the columns, test experiments were conducted to study the removal performance of phosphorus in vertical-flow constructed wetlands.

Six kinds of metal compounds which were CaCl2 , ZnCl2, MgCl2, FeCl3, AlCl3, and CoCl3 were formed nine kinds of different combinations in the alkaline conditions to synthesized LDHs (Layered Double Hydroxides), which were in-situ coated on the surface of zeolites. With the filling of the original and nine kinds of modified zeolites in the columns to simulate a laboratory-scale vertical-flow constructed wetland system, the experiments of purified phosphorus were conducted. Combined removal efficiency with adsorption isotherm data of the ten kinds of zeolites, mechanism for strengthening the removal rates of the phosphorus by the modified zeolites was studied.
