Preparation of lactic acid bacteria compound starter cultures based on pasting properties and its improvement of glutinous rice flour and dough

The effects of 5 lactic acid bacteria(LAB)fermentation on the pasting properties of glutinous rice flour were compared,and suitable fermentation strains were selected based on the changes of viscosity,setback value,and breakdown value to prepare LAB compound starter cultures.The results revealed that Latilactobacillus sakei HSD004 and Lacticaseibacillus rhamnosus HSD005 had apparent advantages in increasing the viscosity and reducing the setback and breakdown values of glutinous rice flour.In particular,the compound starter created using the two abovementioned LAB in the ratio of 3:1 had better performance than that using a single LAB in improving the pasting properties and increasing the water and oil absorption capacity of glutinous rice flour.Moreover,the gelatinization enthalpy of the fermented samples increased significantly.For frozen glutinous rice dough stored for 28 days,the viscoelasticity of frozen dough prepared by compound starter was better than that of control dough,and the freezable water content was lower than that of control dough.These results indicate that compound LAB fermentation is a promising technology in the glutinous rice-based food processing industry,which has significance for its application.

Anticancer Activity of Rice Callus Suspension Cultures from Aromatic Varieties and Metabolites Regulated in Treated Cancer Cell Lines

Tissue culture techniques were used to produce large amounts of bioactive compounds with medicinal potential, overcoming space and time constraints for cancer prevention. Rice callus suspension cultures(RCSC) and seed extracts prepared from aromatic rice varieties were used to evaluate the cytotoxic impact on human colon and lung cancer cell lines, as well as a normal control cell line, using Taxol as a positive control. RCSC and seed extracts from two Indian aromatic rice varieties were applied at different concentrations to treat the cancer cell lines and normal lung fibroblasts over varying time intervals. Apoptosis was assessed in 1:5 dilutions of the A549 and HT-29 cell lines treated with RCSC for 72 h, using propidium iodide staining and flow cytometry. RCSC showed a more potent cytotoxic effect than seed extracts with minimal effect on the normal cell line, in contrast to Taxol. Confocal microscopy and flow cytometry further confirmed the apoptotic effect of RCSC. Gas chromatography-mass spectrometry-based metabolic profiling identified metabolites involved in cytotoxicity and highlighted altered pathways. RCSC is proposed as an alternative source for the development of novel anticancer drugs with reduced side effects.

Effects of Different Culture Conditions and Growth States on the Structure and Hemostatic Properties of Coscinodiscus sp.

As a renewable marine inorganic material,Coscinodiscus sp.has significant potential in the field of rapid hemostasis.However,the low yield of Coscinodiscus sp.seriously limits the application.In this study,two new culture modes were adopted to increase the production of Coscinodiscus sp.,the effect of changes in culture conditions and growth status on the hemostatic activity of diatoms was detected.To prevent Coscinodiscus sp.from sinking in culture,the suspension culture mode was realized by adding0.5%agar.The semi-continuous high nutrient concentration culture mode increased the cell density of Coscinodiscus sp.to 11000cells mL^(-1)and shorten the culture cycle to 5 d.In terms of coagulation activity,the addition of frustules reduced the in vitro coagulation time by half and the activation time of coagulation by 70%.The hemolysis rate and cytotoxicity of frustules harvested in the two culture modes did not change significantly.The results showed that suspension culture mode and high nutrient concentration culture mode only changed the growth state of Coscinodiscus sp.,while the hemostatic performance remained stable.

Efficacy of serum-free cultured human umbilical cord mesenchymal stem cells in the treatment of knee osteoarthritis in mice

BACKGROUND We investigated the efficacy of intra-articular injection of human umbilical cord mesenchymal stem cells(hUC-MSCs)for the treatment of osteoarthritis(OA)progression in the knee joint.Although many experimental studies of hUC-MSCs have been published,these studies have mainly used fetal bovine serumcontaining cultures of hUC-MSCs;serum-free cultures generally avoid the shortcomings of serum-containing cultures and are not subject to ethical limitations,have a wide range of prospects for clinical application,and provide a basis or animal experimentation for clinical experiments.AIM To study the therapeutic effects of serum-free hUC-MSCs(N-hUCMSCs)in a mouse model of knee OA.METHODS Fifty-five male C57BL/6 mice were randomly divided into six groups:The blank control group,model control group,serum-containing hUC-MSCs(S-hUCMSC)group,N-hUCMSC group and hyaluronic acid(HA)group.After 9 weeks of modeling,the serum levels of interleukin(IL)-1β and IL-1 were determined.Hematoxylin-eosin staining was used to observe the cartilage tissue,and the Mankin score was determined.Immunohistochemistry and western blotting were used to determine the expression of collagen type II,matrix metalloproteinase(MMP)-1 and MMP-13.RESULTS The Mankin score and serum IL-1 and IL-1β and cartilage tissue MMP-1 and MMP-13 expression were significantly greater in the experimental group than in the blank control group(P<0.05).Collagen II expression in the experimental group was significantly lower than that in the blank control group(P<0.05).The Mankin score and serum IL-1 and IL-1β and cartilage tissue MMP-1 and MMP-13 levels the experimental group were lower than those in the model control group(P<0.05).Collagen II expression in the experimental group was significantly greater than that in the model control group(P<0.05).CONCLUSION N-hUCMSC treatment significantly alleviate the pathological damage caused by OA.The treatment effects of the ShUCMSC group and HA group were similar.

The Philosophy of He(和):Examined from the Perspectives of Technology and Culture

Pre-modern Chinese crafts,such as iron smelting,cookery,medicine,and the production of vehicles,bows,and arrows indicate the traditional Chinese view of technology as being organic,holistic,and comprehensive.This view of technology is guided by the concept of he(和)and employs the means and methods of he,thus achieving the purport of he.In Chinese,the character he(和)possesses positive connotations.It originated from the meaning of"to season;to add flavoring to"(调和)and that of flavors being"perfectly harmonious"(和美).From this sensory experience,he gradually extended to the abstract levels of materiality,humanity,sociality,"order"(wei位),and "power,situation,force"(shi势).Finally,he was elevated to the supreme level of"qi of great harmony"(taihe zhi qi太和之气),which is comparable to the concept of dao(道).The philosophy of he has exerted wide impact on such areas as technology,art,national character,cultural psychology,and behavior patterns,and has become an integral part of China's inherent culture.The paradoxes and deviations of he hold their own profound philosophical implications that merit further exploration.As humanity confronts significant challenges,such as how we can coexist with others,with technology,and with nature,the ancient Eastern wisdom embodied in he continues to possess practical characteristics and value.

The Implantation and Transmission of Plague Culture by the Five Plague Gods in Shuilu Murals

The Five Plague Gods(五瘟神) in the Shuilu(水陆) murals from the Ming and Qing dynasties exemplify a distinctive manifestation of plague gods image developed under the pedigree of Taoist gods.As a significant system for expelling disasters in Shuilu,the depiction of the Five Plague Gods prominently merges human beings and livestock.This shape form to a large extent,draws on the image of Nuo(傩),a figure reflecting an imagination of the host of plague pathogens.In terms of the numbers of gods,it aligns with the conceptual framework of Wu Xing(五行 the five elements),a foundational principle in traditional Chinese medicine.The internal cultural connection highlights the means of plague prevention and control in China,as well as the external reflection of plague culture.Through multi-dimensional interpretations with the double proof method,this article dissects the formation,core elements,and cultural characteristics of the beliefs in the Five Plague Gods reflected in the Shuilu murals,and transcends mere visual semantics,offering a deeper understanding of these complex cultural symbols.

MACS-W:A modified optical clearing agent for imaging 3D cell cultures

Three-dimensional(3D)cell cultures have contributed to a variety of biological research fields by filling the gap between monolayers and animal models.The modern optical sectioning microscopic methods make it possible to probe the complexity of 3D cell cultures but are limited by the inherent opaqueness.While tissue optical clearing methods have emerged as powerful tools for investigating whole-mount tissues in 3D,they often have limitations,such as being too harsh for fragile 3D cell cultures,requiring complex handling protocols,or inducing tissue deformation with shrinkage or expansion.To address this issue,we proposed a modified optical clearing method for 3D cell cultures,called MACS-W,which is simple,highly efficient,and morphology-preserving.In our evaluation of MACS-W,we found that it exhibits excellent clearing capability in just 10 min,with minimal deformation,and helps drug evaluation on tumor spheroids.In summary,MACS-W is a fast,minimally-deformative and fluorescence compatible clearing method that has the potential to be widely used in the studies of 3D cell cultures.

Protective Effect of Dietary Yeast Cultures on Lipopolysaccharide-induced Oxidative Stress,Immune and Inflammatory Responses in Pseudobagrus ussuriensis

This study aimed to evaluate the effects of dietary yeast culture(YC)on lipopolysaccharide(LPS)-induced oxidative stress,immune and inflammatory response in P.ussuriensis.The fish were randomly assigned into three groups as the control group,LPS group and YC+LPS group.The fish in the control were fed diet with no YC supplementation and no LPS challenge,and the fish in the LPS group or YC+LPS group were fed diet supplemented with no YC or 20 g·kg^(-1)YC,and with LPS challenge,respectively.The results showed that compared with the control group,intestinal total antioxidant capacity(T-AOC)level and superoxide dismutase(SOD)activity were significantly decreased,while intestinal malondialdehyde(MDA),plasma aspartate transaminase(AST)and alanine transaminase(ALT)levels were significantly increased in the LPS group(P<0.05).Besides,lower plasma alkaline phosphatase(ALP),alternative complement pathway(ACH50)activity and the albumin(ALB)level,as well as higher lysozyme(LZM)activity,were also found in the LPS group.However,dietary 20 g·kg^(-1)YC supplementation could relieve the above LPS-induced changes in Pseudobagrus ussuriensis.Furtherly,LPS challenge could significantly up-regulate gene expression of interleukin-8(IL-8),heat shock protein(HSP70)and NF-κBp65 except for toll-like receptors 2(TLR2),while dietary 20 g·kg^(-1)YC supplementation suppressed the increased expression of NF-κBp65 and IL-8 induced by LPS in P.ussuriensis.In summary,LPS challenge could induce immune impairment,oxidative stress and hepatic damage,and the protective effect of dietary 20 g·kg^(-1)YC supplementation on LPS-induced immune impairment and oxidative stress was observed in the present study,which was associated with the enhanced levels of antioxidant enzymes and immune parameters.Also,dietary 20 g·kg^(-1)YC supplementation could suppress LPS-induced inflammatory response by down-regulating NF-κBp65,HSP70 and IL-8 gene expression.

Investigation of the Acceptability of Cultured Meat in University Students

Background: Over the past 20 years, cultured meat has drawn a lot of public attention as a potential solution to issues with animal husbandry, including inadequate use of natural sources, improper animal welfare practices, and possible risks to public health and safety. The novel method of producing meat through culture reduces the need for animals to produce muscle fiber, thereby obviating the necessity for animal slaughter. Apart from its ethical advantages, cultured meat presents a possible way to fulfill the expanding need for food among growing populations. The purpose of this research was to find out whether Turkish students would be willing to pay for and accept cultured meat. Technique: Method: 371 university students who willingly consented to fill out a questionnaire and provide demographic data make up the research sample. Questions from previous studies on the acceptability of cultured meat were compiled to create the survey. The research’s data collection took place in March and April of 2022. The research was completed in June 2022 after the data had been processed and analyzed. Results: The results showed that the majority of participants were female and had omnivorous eating habits. Based on the results of the Bonferroni correction test, students with a higher intention to purchase and consume cultured meat were those who received economics and business education. Students with two years of university education had a higher overall survey score than those with four years of education (p < 0.05). Furthermore, it is discovered that there is a negative correlation between the participants’ ages and their Factor 2 (using cultured meat as an alternative to industrial meat) and Factor 3 (consuming and purchasing it) section points (r = -109, p = 0.036) (r = -0.121, p = 0.019). In conclusion, university students generally have a negative outlook on health-related issues, such as eating cultured meat as an alternative.
