Progress in Preparation and Application of Gel-Emulsions

Compared to conventional emulsions, gel-emulsions have a higher internal phase volume fraction, unique structures and properties, higher viscosity, and tunable internal structures. These advantages make them widely applicable in the cosmetics industry, food industry, aerospace, and biomedicine, with significant potential in the development of new materials and high-performance products. The factors affecting the stability of gel-emulsions, as well as the types of stabilizers required for their preparation (including solid particles, surfactants, and small molecule gelators), and the corresponding preparation methods (including the one-step method, two-step method, and phase inversion method) are reviewed in this article. The applications of gel-emulsions in porous materials, food, cosmetics, and stimuli-responsive materials are introduced, and future research directions are also discussed.

Pitavastatin attenuates AGEs-induced mitophagy via inhibition of ROS generation in the mitochondria of cardiomyocytes

This study aimed to investigate whether pitavastatin protected against injury induced by advanced glycation end products products（AGEs） in neonatal rat cardiomyocytes,and to examine the underlying mechanisms.Cardiomyocytes of neonatal rats were incubated for 48 hours with AGEs（100 μg/mL）,receptor for advanced glycation end products（RAGE）,antibody（1 μg/mL） and pitavastatin（600 ng/mL）.The levels of p62 and beclinl were determined by Western blotting.Mitochondrial membrane potential（△Ψm） and the generation of reactive oxygen species（ROS） were measured through the JC-1 and DCFH-DA.In the AGEs group,the expression of beclinl was remarkably increased compared to the control group,while the expression of p62 was significantly decreased.AGEs also markedly decreased △Ψm and significantly increased ROS compared with the control group.After treatment with RAGE antibody or pitavastatin,the level of beclinl was markedly decreased compared with the AGEs group,but the level of p62 was remarkably increased.In the AGEs ＋ RAGE antibody group and AGEs＋ pitavastatin group,△Ψm was significantly increased and ROS was remarkably decreased compared with the AGEs group.In conclusion,AGEs-RAGE may induce autophagy of cardiomyocytes by generation of ROS and pitavastatin could protect against AGEs-induced injury against cardiomyocytes.

Influence of high overload on the collimating lenses of laser ranging systems

Collimating lenses are an important component of laser ranging systems,and high overload environments severely affect the beam shaping effect of such lenses.This study proposes a buffer isolation method on the basis of impact stress wave attenuation theory for collimating lens spacers,ANSYS finite element software was applied to simulate the high load dynamics of collimating lenses,and the buffer isolation performance of different materials and composite structures was compared and analysed.Optical simulation analysis of the collimating lenses under different buffer conditions was performed using ZEMAX software to study the mechanism by which a high overload affects the collimating lenses.High overload and optical shaping experiments based on theoretical analysis were further conducted.Results showed the superiority of butadiene rubber to polytetrafluoroethylene after application of 70000 g impact acceleration.The combination-gasket method was superior to the single-gasket method,and the sandwich combination-gasket method was superior to the double-layer combination-gasket method.

Association of glutathione S-transferase T1 and M1 gene polymorphisms with ischemic stroke risk in the Chinese Han population

Atherosclerosis plays an important role in ischemic stroke, and oxidative stress participates in the entire process of atherosclerosis. Glutathione S-transferase （GST） acting with other antioxidant enzymes can eliminate reactive oxygen species and protect cells against oxidative damage. To assess the association of glutathione S-transferase （GSTT1 and GSTM1） gene polymorphisms with ischemic stroke in the Chinese Han population, the present study selected 315 patients with ischemic stroke and 210 healthy controls for comparison. GSTT1 and GSTM1 genotypes were determined using polymerase chain reactions, electrophoresis and imaging analysis. No obvious evidence of GSTTI-nulI, GSTMI-null and GSTTI/GSTMI-double null genotype distribution differences was found between case and control groups or between genders. Subgroup analysis showed that the risk of stroke was increased when hypertension was accompanied by GSTTl-null （odds ratio （OR） = 2.996, P 〈 0.001） and GSTMl-null （OR = 3.680, P 〈 0.001 ） genotypes; diabetes mellitus was accompanied by GSTTI-null （OR = 1.860, P = 0.031） and GSTMI-null （OR = 2.444, P = 0.002） genotypes, and smokers showed a GSTTl-null genotype （OR = 2.276, P = 0.003）. GSTT1- and GSTMl-null genotypes may interact synergistically with hypertension, diabetes mellitus and smoking to increase the incidence risk of ischemic stroke.

African swine fever virus MGF505-3R inhibits cGAS-STING-mediated IFN-βpathway activation by degrading TBK1

African swine fever virus(ASFV)is an important pathogen causing acute infectious disease in domestic pigs and wild boars that seriously endangers the global swine industry.As ASFV is structurally complex and encodes a large number of functional proteins,no effective vaccine has been developed to date.Thus,dissecting the mechanisms of immune escape induced by ASFV proteins is crucial.A previous study showed that the ASFV-encoded protein is an important factor in host immunity.In this study,we identified a negative regulator,MGF505-3R,that significantly downregulated cGAS/STING-and poly(dG:dC)-mediated IFN-βand interferon stimulation response element(ISRE)reporter activity and suppressed IFNB1 and IFIT2 mRNA levels.In addition,TBK1,IRF3 and IκBαphosphorylation levels were also inhibited.Mechanistically,MGF505-3R interacted with cGAS/TBK1/IRF3 and targeted TBK1 for degradation,thereby disrupting the cGAS-STING-mediated IFN-βsignaling pathway,which appears to be highly correlated with autophagy.Knockdown MGF505-3R expression enhanced IFN-βand IL-1βproduction.Taken together,our study revealed a negative regulatory mechanism involving the MGF505-3R-cGAS-STING axis and provided insights into an evasion strategy employed by ASFV that involves autophagy and innate signaling pathways.

Transmission properties of microwave in rectangular waveguide through argon plasma

To study the impact of plasma generated by microwave breakdown on the propagation properties of microwave in high power microwave(HPM) devices, a three-dimensional(3-D) fluid model of argon plasma slab in rectangular waveguide is established and calculated by the finite-difference-time-domain(FDTD) method. A rectangular waveguide with a breakdown chamber filled with argon is set as the physics model, and HPM with frequency of 3–50 GHz propagates through this physics model. The time evolutions of the breakdown process are investigated, the reflection, transmission, and absorption coefficients of HPM are calculated, and the influences of some important parameters, including the thickness of the plasma slab and the microwave frequency on the propagation properties of the microwave are shown. Results of this work can offer theoretical instructions for suppressing the influence of breakdown to the performance of HPM devices, and for the use of microwave breakdown, such as the design of plasma limiter or absorber in HPM devices.

Research on Cultural Consumption of Urban Elderly Groups Under the Multimodal “New Media+”-Illustrated by the Example of Shanghai

In recent years,the provision of high-quality elderly care services for an ageing society has become more important in China’s social developments.As an indispensable part of the process,meeting the spiritual life needs of the elderly groups has received increasing attention.Taking Shanghai,an international metropolis with diverse forms of cultural consumption and high cultural consumption demand,as an example,this paper examines the modalities of combining coffee culture with cultural consumption of middle and old age groups,taking coffee consumption of old age groups as a research object and finding that:Firstly,coffee consumption combined with new media presents multimodal coffee consumption,which promotes the multi-level popularity of coffee culture.Secondly,coffee consumption can meet the spiritual needs of Shanghai middle-aged and elderly groups such as socialization and the inheritance of coffee culture to a certain extent.The cultural consumption of coffee consumption provides an important reference for the international elderly care service in Shanghai.

The Concept of Shared Destiny in the Ainu Spiritual Belief

The Ainu are the only ethnic minority officially recognized in Japan.Ainu culture is not only a new entry point for understanding Japanese culture,but also an important medium for exploring ancient Asian civilization.This article analyzes the Ainu folk songs and legends and other oral literature and discovers:The Ainu people respect and thank the gods,and accept the gifts and punishments of the gods.However,the Ainu claim that human beings have autonomy through the belief that humans have the right to punish gods,and those humans and gods can strive for an equal two-way relationship.In addition,the Ainu emphasize the importance of coexistence between humans and other creatures in nature.It is believed that hunting and fishing are not blasphemy,but acceptances of the gifts from the gods.However,it is advocated that human beings and other creatures should give each other living space and maintain the balance of symbiosis and coexistence.The Ainu belief in relative equality with gods and coexistence with nature reflects the concept of“shared destiny”in ancient Asian civilizations.It provides an important reference for the development of modern human society.

Rumen-protected lysine supplementation improved amino acid balance,nitrogen utilization and altered hindgut microbiota of dairy cows

This study was conducted to evaluate the effects of dietary crude protein(CP)and rumen-protected lysine(RPL)supplementation on lactation performance,amino acid(AA)balance,nitrogen(N)utilization and hindgut microbiota in dairy cows.Treatments were in a 2×2 factorial arrangement,and the main effects were CP concentration(16%vs.18%)and RPL supplementation(with or without RPL at40 g/cow per day).Forty cows were randomly allocated to 4 groups:low-CP diet(LP),low-CP diet plus RPL(LPL),high-CP diet(HP),high-CP diet plus RPL(HPL).The experiment was conducted for 8 weeks.Results showed that RPL increased the dry matter intake(P<0.01),milk protein yield(P=0.04)and energy corrected milk(P=0.04),and tended to increase milk fat yield(P=0.06)and fat corrected milk(P=0.05).Cows in the HP group tended to have higher milk urea N(P=0.07).Plasma concentrations of Arg,Ile,Lys,Met,Pro,total essential AA and total nonessential AA were increased by RPL(P<0.05).The total essential AA,total nonessential AA and most AA(except Ile,Phe,Gly and Pro)were increased in the HP group(P<0.05).N excretion was increased in the HP group through an increase in urea N excretion(P<0.01)and an upward trend in plasma urea N(P=0.07).In addition,RPL tended to increase milk protein N secretion(P=0.08),milk N(P=0.07)and microbial protein synthesis(P=0.06),and decreased plasma urea N(P<0.001).In the hindgut,the bacterial community were different between the LP and LPL groups(P<0.01).The probiotic abundances of Christensenellaceae_R-7_group and Acinetobacter were increased by RPL(P=0.03 and 0.03,respectively).The pathogenic abundances of Clostridium_sensu_stricto_1(P<0.001)and Turicibacter(P<0.01)were decreased by RPL.In conclusion,supplementing RPL with low dietary CP could balance AA supply and increase milk protein yield,resulting in an improvement in N utilization efficiency,and altered the composition of the hindgut microbiota to favor the lactation performance of dairy cows.
