Can nonvolatile tastants be smelled during food oral processing?

While accumulating evidence implied the involvement of retro-nasal sensation in the consumption of nonvolatile taste compounds, it is still unclear whether it was caused by the taste compounds themselves, and if so, how can they migrate from the oral to nasal cavity. At first, we proposed aerosol particles as an alternative oral-nasal mass transfer mechanism. The high-speed camera approved that aerosol particles could be generated by the typical oral and pharynx actions during food oral processing; while the narrow-band imaging of nasal cleft and mass spectrometry of nostril-exhaled air approved the migration of aerosol within the oral-nasal route. Then, the "smelling" of taste compounds within the aerosol particles was testified. The four-alternative forced choices (4AFC) approved that the potential volatile residues or contaminants within the headspace air of pure taste solution cannot arouse significant smell, while the taste compounds embedded in the in vitro prepared aerosol particles can be "smelled" via the ortho route. The "smell" of sucrose is very different from its taste and the "smell" of quinine, implying its actual olfaction. The sweetness intensity of sucrose solution was also reduced when the volunteers' noses were clipped, indicating the involvement of retro-nasal sensation during its drinking. At last, the efficiency of aerosol as a mechanism of oral-nasal mass transfer was demonstrated to be comparable with the volatile molecules under the experimental condition, giving it the potential to be a substantial and unique source of retro-nasal sensation during food oral processing.

Transcriptome and genome sequencing investigating the molecular characteristics of patients with varicocele infertility.

The prevalence of varicoceles in male infertility is increasing; however, the exact mechanism is unknown, and no direct studies of varicose spermatic veins have been conducted. Three patients with varicocele infertility were included to explore the possible factors that cause varicocele infertility, and varicose and nearby normal veins were harvested by varicocelectomy. RNA sequencing was performed on six vascular samples, followed by Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analyses of the screened differential expressed genes which were validated by quantitative reverse transcription-polymerase chain reaction. The genomes of the patients were analysed using next-generation sequencing to screen for genetic factors behind varicocele infertility. 1171 genes were upregulated and 2772 were downregulated in varicose spermatic veins compared with those in normal veins. These genes were significantly enriched in the alcohol consumption pathway. HIST1H4C, HIST1H4F, HIST1H4K, TM9SF1, and TMEFF1 were significantly differentially expressed. The genomic results identified patients with mutations in CFTR, NANOS1, SRCAP, GATA4, GCM2, TUBB1, ALDH7A1, ANTXR1, and MAP3K1. In conclusion, our results indicated that Alcohol consumption may be a cause of varicoceles. Mutations in certain genes, such as CFTR, may be a cause of male infertility due to varicoceles.

Transcriptomics and proteomics analysis to explore the mechanism of Yishen Tongluo formula repairing sperm DNA damage in rats.

The sperm DNA fragmentation index (DFI) is an objective indicator of male fertility. Currently, effective treatments for high sperm DFI are limited and traditional Chinese medicine (TCM) has certain advantages in this aspect. Yishen Tongluo formula (YSTL), a TCM formula, has been found to reduce DFI in patients. To better understand the mechanisms underlying its activity, we used transcriptomics and proteomics to analyse the potential target gene YSTL repairing tripterygium glycosides (TGs)-mediated sperm DNA damage in rats, followed by validation analyses using RT-qPCR and western blotting, which showed that relative to the control group, DFI was markedly elevated in the TGs group, but markedly lower in the YSTL group relative to the TGs group. KEGG pathway analysis of 119 differentially expressed genes and 158 DEPs identified using trend analysis revealed that they were enriched for apoptosis and base excision repair at the transcriptomic level and for microRNAs in cancer and complement and coagulation cascades at the proteomic level. Ttr and Pnpla2 were identified as potential target genes for YSTL. Our data show that YSTL can protect rat sperm DNA from TGs-induced damage, which may be related to apoptosis, DNA repair and other pathways, and the possible target genes are Ttr and Pnpla2.

In situ oral lubrication and smoothness sensory perception influenced by tongue surface roughness.

BACKGROUND: The human tongue is important in the oral processing of food and in sensory perception. Tongue topography could influence delicate differences in sensory perception. It is hypothesized that tongue surface roughness could alter oral lubrication status and affect perception of smoothness. Fifteen participants with varying levels of tongue surface roughness were recruited and tested. Participants' in situ oral lubrication status without and after consumption of fluid food (milk with varying fat content and maltodextrin solutions with different shear viscosities) was measured. Participants' smoothness sensory scores were also recorded. RESULTS: The in situ friction coefficient (0.299-1.505) was significantly positively correlated with tongue-surface roughness (54.6-140.0 µm) in all types of test fluid samples across participants. Oral lubrication was significantly decreased when participants consumed the test fluid samples compared with no liquid food consumption, for all test fluid sample types (P < 0.05). No significant differences in in situ friction coefficient were found after participants consumed different test fluid samples, and this was mainly attributed to the limited quantities of fluid residuals in the oral cavity after expectoration. Participants whose tongue surface roughness differed did not exhibit significant differences in smoothness perception with different test fluid samples. CONCLUSION: Tongue surface roughness has a strong impact on in situ oral lubrication, and fluid food intake reduces in situ oral lubrication significantly. Saliva film and tongue surface roughness might play greater roles in oral lubrication and smoothness sensory perception if fluid is expectorated after consumption. The association between oral physiology and texture perception still needs further elucidation. © 2021 Society of Chemical Industry.

Wine astringency: more than just tannin-protein interactions.

Red wines are characterized by their astringency, a very important sensory attribute that affects the perceived quality of wines. Three mechanisms have been proposed to explain astringency, and two theories describe how these mechanisms work in an integrated manner to produce tactile sensations such as drying, roughening, shrinking and puckering. The factors involved include not only tannins and salivary proteins, but also anthocyanins, grape polysaccharides and mannoproteins, as well as other wine matrix components that modulate their interactions. These multifactorial interactions could be responsible for different sensory responses and therefore need to be further studied. This review presents the latest advances in astringency perception and its possible origins, with special attention on the interactions of components, their impact on oral perception and the development of astringency sub-qualities. Future research efforts should concentrate on understanding the mechanisms involved as well as on the limiting factors related to the conformation and stability of the tannin-salivary protein complexes. © 2021 Society of Chemical Industry.

Consensus on the terminologies and methodologies for masticatory assessment.

A large number of methodological procedures and experimental conditions are reported to describe the masticatory process. However, similar terms are sometimes employed to describe different methodologies. Standardisation of terms is essential to allow comparisons among different studies. This article was aimed to provide a consensus concerning the terms, definitions and technical methods generally reported when evaluating masticatory function objectively and subjectively. The consensus is based on the results from discussions and consultations among world-leading researchers in the related research areas. Advantages, limitations and relevance of each method are also discussed. The present consensus provides a revised framework of standardised terms to improve the consistent use of masticatory terminology and facilitate further investigations on masticatory function analysis. In addition, this article also outlines various methods used to evaluate the masticatory process and their advantages and disadvantages in order to help researchers to design their experiments.

Pharmacokinetics and bioavailability of ipatasertib in dog plasma using LC/MS/MS.

A rapid, sensitive, and reliable liquid chromatography-tandem mass spectrometric method was developed to quantify ipatasertib in dog plasma. The dog plasma sample was deproteinated by using acetonitrile with ulixertinib as an internal standard followed by separation on a Spursil C18 -EP column with a gradient mobile phase comprising 2 mM ammonium acetate containing 0.1% formic acid and acetonitrile. Positive ion electrospray was used, and multiple reaction monitoring transitions were m/z 458.2 > 387.2 for ipatasertib and m/z 433.1 > 262.1 for the internal standard. The developed method was validated with a linear range of 0.3-1500 ng/mL, and with correlation coefficient greater than 0.9989. The lower limit of quantification was 0.3 ng/mL. The intra- and inter-day precision ranged from 3.58 to 14.32%, whereas the intra- and inter-day accuracy was in the range of -2.50-13.25%. No carry-over and matrix effects were observed under the current conditions. The extraction recovery was demonstrated to be greater than 85.43%. Ipatasertib was stable during the storage, processing, and determination. The validated assay was further successfully applied to a pharmacokinetic study of ipatasertib in dogs after oral and intravenous administrations. The bioavailability of ipatasertib was determined to be 19.3%.

[Yishen Tongluo Recipe combined with minimally invasive surgery for the treatment of varicocele-associated asthenospermia].

OBJECTIVE: To observe the clinical effect of Yishen Tongluo Recipe (YTR) combined with minimally invasive surgery (MIS) in the treatment of varicocele-associated asthenospermia (of the kidney-deficiency and collateral-obstruction type). METHODS: We randomly divided 116 patients with varicocele-associated asthenospermia and up to the inclusion criteria into three groups and treated them by YTR combined with MIS (low spermatic vein ligation at the external inguinal ring orifice under the microscope) (the YTR+MIS group, n = 39), YTR alone (the YTR group, n = 38), or MIS alone (the MIS group, n = 39). At 12 weeks after treatment, we compared the total effectiveness rate, the percentage of progressively motile sperm (PMS), sperm straight line velocity (VSL), sperm DNA fragmentation index (DFI) and symptoms among the three groups of patients. RESULTS: After treatment, the total effectiveness rate was significantly higher in the YTR+MIS than in the YTR and the MIS group (89.74% vs 63.16% and 64.10%, P < 0.05), and so were the percentage of PMS (31.67 ± 3.93 vs 24.48 ± 3.15 and 25.57 ± 3.37, P < 0.05) and VSL (ï¼»30.19 ± 5.32ï¼½ vs ï¼»27.19 ± 5.48ï¼½ and ï¼»27.55 ± 5.24ï¼½ µm/s, P < 0.05), but the DFI was remarkably lower in the former than in the latter two groups (11.25 ± 8.27 vs 15.87 ± 5.45 and 15.26 ± 4.36, P < 0.05). The symptoms were improved more significantly in the YTR+MIS than in the YTR and MIS groups (P < 0.05). CONCLUSIONS: Yishen Tongluo Recipe combined with minimally invasive surgery, as an effective and safe strategy, can significantly improve sperm quality and sperm DNA integrity in patients with varicocele-associated asthenospermia.

[Protective effect of Yishen Tongluo Recipe against benzo(a)pyrene-induced sperm DNA methylation changes in male rats].

OBJECTIVE: To explore the protective effect of Yishen Tongluo Recipe (YTR) against aberrant sperm DNA methylation in male rats exposed to benzo(a)pyrene (BaP). METHODS: Thirty male SD rats of the SPF grade were randomly divided into three groups of equal number: solvent control, BaP exposure and YTR intervention. The animals of the solvent control group were injected intraperitoneally with 0.5% DMSO while those of the other two groups with BaP at 0.1 mg/kg/d, all for 60 days, and at 31 days of BaP exposure, those of the YTR group were treated intragastrically with YTR for 30 days. Then, the left epididymides were harvested from all the rats and sperm suspensions collected and centrifuged for extraction of sperm DNA. The methylated DNA immunoprecipitation sequencing (MeDIP-seq) technique was used to detect the whole-genome DNA methylation in different groups. RESULTS: Exposure to BaP induced the up-regulation of 828 genes encoding mRNA in the sperm DNA, while YTR intervention produced a significant protective effect on the transforming growth factor ß3 (TGF-ß3), cystic fibrosis transmembrane conductance regulator (CFTR) and recombination activating gene 1 (RAG1), and down-regulated the expressions of 3 227 genes. BaP exposure also caused the up-regulation of 783 genes encoding lncRNA in the sperm DNA, and YTR treatment exhibited an evident protective effect on 62 of the up-regulated genes, induced the down-regulation of 3 378 genes, and showed a protective effect on 56 of the down-regulated genes. CONCLUSIONS: YTR has a protective effect against aberrant sperm DNA methylation in male rats exposed to BaP, which may be associated with lncRNA.

miR-340 Inhibits Proliferation and Induces Apoptosis in Gastric Cancer Cell Line SGC-7901, Possibly via the AKT Pathway.

BACKGROUND Gastric cancer is among the most common types of cancer, with high morbidity and mortality. MicroRNAs (miRNAs) play vital roles in the tumorigenesis and biology of gastric cancer. This study aimed to reveal the role of miR-340 in gastric cancer cell proliferation and apoptosis and to elucidate the potential mechanisms. MATERIAL AND METHODS Human gastric cancer cells SGC-7901 were used in this study for cell transfection with miR-340 mimic or inhibitor. After transfection, cell viability, proliferation, and apoptosis were examined by MTT, BrdU, and flow cytometry assays, respectively. The protein level changes of p27, p21, Caspase 3 (CASP3), B cell lymphoma 2 (BCL2), BCL2-associated X protein (BAX), and v-AKT murine thymoma viral oncogene (AKT) were detected by Western blot. RESULTS Overexpression of miR-340 significantly reduced cell viability and proliferation (P<0.01), and induced cell apoptosis (P<0.01) of SGC-7901. miR-340 elevated the protein level of cell cycle inhibitor p27, but did not affect the level of p21. Apoptosis-related factors pro-CASP3, cleaved-CASP3, and BAX were promoted, and BCL2 was inhibited by miR-340. miR-340 also suppressed the phosphorylation of AKT. Opposite effects were detected when SGC-7901 cells were transfected with miR-340 inhibitor. CONCLUSIONS These results indicate that miR-340 can inhibit proliferation and induce apoptosis of SGC-7901 cells, suggesting its roles in protecting against gastric cancer. The roles of miR-340 in gastric cancer cells may be associated with its regulation of the AKT pathway. Thus, miR-340 may be a potential therapeutic strategy for gastric cancer treatment.

Development of International Terminology and Definitions for Texture-Modified Foods and Thickened Fluids Used in Dysphagia Management: The IDDSI Framework.

Dysphagia is estimated to affect ~8% of the world's population (~590 million people). Texture-modified foods and thickened drinks are commonly used to reduce the risks of choking and aspiration. The International Dysphagia Diet Standardisation Initiative (IDDSI) was founded with the goal of developing globally standardized terminology and definitions for texture-modified foods and liquids applicable to individuals with dysphagia of all ages, in all care settings, and all cultures. A multi-professional volunteer committee developed a dysphagia diet framework through systematic review and stakeholder consultation. First, a survey of existing national terminologies and current practice was conducted, receiving 2050 responses from 33 countries. Respondents included individuals with dysphagia; their caregivers; organizations supporting individuals with dysphagia; healthcare professionals; food service providers; researchers; and industry. The results revealed common use of 3-4 levels of food texture (54 different names) and ≥3 levels of liquid thickness (27 different names). Substantial support was expressed for international standardization. Next, a systematic review regarding the impact of food texture and liquid consistency on swallowing was completed. A meeting was then convened to review data from previous phases, and develop a draft framework. A further international stakeholder survey sought feedback to guide framework refinement; 3190 responses were received from 57 countries. The IDDSI Framework (released in November, 2015) involves a continuum of 8 levels (0-7) identified by numbers, text labels, color codes, definitions, and measurement methods. The IDDSI Framework is recommended for implementation throughout the world.

Knockdown resistance of Anopheles sinensis in Henan province, China.

BACKGROUND: Vivax malaria was historically epidemic in Henan Province of China and Anopheles sinensis was the main vectors and poor farming communities bare the greatest burden of disease. Knockdown resistance in An. sinensis is one of the mechanisms of resistance against pyrethroids. In the present study, the frequency of mutations from An. sinensis was examined in Henan province, China. METHODS: Anopheles was collected from Kaifeng, Tongbai, Tanghe, Pingqiao, Shihe, and Yongcheng counties of Henan province in 2013. Molecular identification of Anopheles species was conducted by polymerase chain reaction (PCR) amplifying the internal transcribed spacer 2 (ITS2). Part of the IIS6 domain of the para-type sodium channel protein gene was polymerase chain reaction-amplified and directly sequenced. Frequency and geographic difference of kdr gene mutant types were analysed. RESULTS: 208 Anopheles were received molecular identification, of which 169 (81.25%) were An. sinensis, 25 (12.02%) were Anopheles yatsushiroensis, and 12 (5.77%) were Anopheles lesteri. A 325 bp fragment of the para-type sodium channel gene including position 1014 was successfully sequenced from 139 Anopheles, of which 125 (89.93%) were An. sinensis, 12 (8.63%) were An. yatsushiroensis, 2 (1.44%) were An. lesteri. The molecular analyses revealed that mutations existed at codon 1014 in An. sinensis but not in An. yatsushiroensis and An. lesteri. Frequency of kdr mutation was 73.60% (92/125) from population of An. sinensis in Henan province, of which L1014F (TTT + TTC) allele frequencies accounted for 46.40% (58/125), and was higher than that of L1014C(TGT) which accounted for 27.20% (34/125) ( χ2 = 55.423, P < 0.001). The frequency of kdr mutation in Kaifeng county was 100% (49/49), and was higher than that of 37.93% (11/29) in Tongbai, 54.55% (6/11) in Pingqiao, 50.00% (3/3) in Shihe, and 62.50% (10/16) in Yongcheng county, respectively (χ2 = 39.538, P < 0.001; χ2 = 24.298, P < 0.001; χ2 = 25.913, P < 0.001; χ2 = 20.244, P < 0.001). While 92.86% (13/14) frequency of kdr mutation was found in Tanghe county, which was higher than that in Tongbai county (χ2 = 11.550, P = 0.0018). CONCLUSIONS: A high frequency of kdr gene mutations from population of An. sinensis in Henan province was found.

Prognostic and clinical significance of claudin-4 in gastric cancer: a meta-analysis.

BACKGROUND: The current reports on the association of claudin-4 expression with gastric cancer outcome were inconsistent. Thus, we conducted a meta-analysis to assess the association of claudin-4 expression with the prognosis and clinical parameters more precisely. METHODS: Systematic searches on PubMed, Embase, and Cochrane Library prior to December 2014 were performed. The pooled hazard ratio (HR) with its 95 % confidence interval (95 %CI) was used to assess the prognostic value of claudin-4 expression with gastric cancer patients, and the pooled odds ratio (OR) with its 95 %CI was used to assess the association with clinical parameters. RESULTS: Nine studies with a total of 1265 gastric cancer patients were included. Overall, the pooled results showed that over-expression of claudin-4 was associated with a poor survival in gastric cancer patients (HR: 2.01, 95 % CI: 1.62-2.50). Over-expression of claudin-4 was also associated with advanced stage (OR: 1.96, 95 % CI: 1.08-3.56) and lymphoid node metastasis (OR: 1.72, 95 % CI: 1.05-2.81) of gastric cancer patients. No significant publication bias was found among the studies (P > 0.05). CONCLUSIONS: This meta-analysis shows that over-expression of claudin-4 is associated with progress of gastric cancer and poor prognosis of gastric cancer patients.

The influence of food texture and liquid consistency modification on swallowing physiology and function: a systematic review.

Texture modification has become one of the most common forms of intervention for dysphagia, and is widely considered important for promoting safe and efficient swallowing. However, to date, there is no single convention with respect to the terminology used to describe levels of liquid thickening or food texture modification for clinical use. As a first step toward building a common taxonomy, a systematic review was undertaken to identify empirical evidence describing the impact of liquid consistency and food texture on swallowing behavior. A multi-engine search yielded 10,147 non-duplicate articles, which were screened for relevance. A team of ten international researchers collaborated to conduct full-text reviews for 488 of these articles, which met the study inclusion criteria. Of these, 36 articles were found to contain specific information comparing oral processing or swallowing behaviors for at least two liquid consistencies or food textures. Qualitative synthesis revealed two key trends with respect to the impact of thickening liquids on swallowing: thicker liquids reduce the risk of penetration-aspiration, but also increase the risk of post-swallow residue in the pharynx. The literature was insufficient to support the delineation of specific viscosity boundaries or other quantifiable material properties related to these clinical outcomes. With respect to food texture, the literature pointed to properties of hardness, cohesiveness, and slipperiness as being relevant both for physiological behaviors and bolus flow patterns. The literature suggests a need to classify food and fluid behavior in the context of the physiological processes involved in oral transport and flow initiation.

[Individualized neurosurgical treatments of spastic cerebral palsy].

OBJECTIVE: To explore the outcomes of individualized neurosurgical treatments of spastic cerebral palsy. METHODS: A total of 452 spastic cerebral palsy patients undergoing microneurosurgery during March 2006 and December 2011 were retrospectively analyzed. Performed on the basis of clinical manifestations, comprehensive procedures included selective cutting of neck or lumbosacral dorsal root ganglia (SPR, n = 182) for multiple muscle spasm, selective peripheral neurotomy (SPN, n = 270) for focal muscle spasm, line tendon lengthening or cutting and orthopedic surgery (n = 116) for tendon contracture plus limb deformities and carotid artery adventitia endarterectomy (n = 46) for salivation plus athetoid. RESULTS: The average follow-up period was 18 (10-24) months. The limb spasm relief rate of SPR was 95.6% and that of SPN 98.3%. And the postoperative symptom improvement rate of common carotid arterial adventitia stripping was 91.3%. There were 8 cases (4.4%) of recurrent spasticity after SPR and 28 (10.4%) after SPN. CONCLUSION: Offering individualized microsurgical treatments on the basis of clinical manifestations is essential for patients with spastic cerebral palsy.

The enhancement mechanisms of mucin and lactoferrin on α-amylase activity in saliva: Exploring the interactions using QCM-D and molecular docking.

α-Amylase activity differs between individuals and is influenced by dietary behavior and salivary constituents, but limited information is available on the relationship between α-amylase activity and saliva components. This study investigated the impact of salivary proteins on α-amylase activity, their various correlations, the effect of mucin (MUC5B and MUC7) and lactoferrin on the enzymatic kinetics of α-amylase, and the mechanisms of these interactions using the quartz crystal microbalance with dissipation (QCM-D) technique and molecular docking. The results showed that α-amylase activity was significantly correlated with the concentrations of MUC5B (R2 = 0.42, p < 0.05), MUC7 (R2 = 0.35, p < 0.05), and lactoferrin (R2 = 0.35, p < 0.05). An in vitro study demonstrated that α-amylase activity could be significantly increased by mucins and lactoferrin by decreasing the Michaelis constant (Km) of α-amylase. Moreover, the results from the QCM-D and molecule docking suggested that mucin and lactoferrin could interact with α-amylase to form stable α-amylase-mucin and α-amylase-lactoferrin complexes through hydrophobic interactions, electrostatic interactions, Van der Waals forces, and hydrogen bonds. In conclusion, these findings indicated that the salivary α-amylase activity depended not only on the α-amylase content, but also could be enhanced by the interactions of mucin/lactoferrin with α-amylase.

Umami Altering Salivary Proteome: A Study across a Sensitivity Spectrum on Subjects.

This study delved into the relationship between umami taste sensitivity (UTS) and variations in the salivary proteome among 12 healthy nonsmokers utilizing 4D data-independent acquisition-based proteomics. By assessing UTS through monosodium l-glutamate (MSG) detection thresholds, we discovered notable differences: individuals with high UTS detected umami at significantly lower MSG concentrations (0.20 ± 0.12 mM) compared to their low UTS counterparts (2.51 ± 1.21 mM). Both groups showed an upregulation of the S100A1 protein under MSG stimulation, indicating a potent biochemical response to umami stimuli. The high UTS group exhibited enhanced metabolic pathways including those for amino acid, lipid, and organic acid biosynthesis, essential for maintaining taste receptor functionality and enhancing signal transduction. This group also demonstrated increased activity in cytochrome P450 enzymes and ribonucleoprotein complexes, suggesting a readiness to manage metabolic challenges and optimize umami perception. In contrast, the low UTS group showed adaptive mechanisms, possibly through modulation of receptor availability and function, with an upregulation of structural and ribosomal proteins that may support taste receptor production and turnover. These findings suggest that varying biological mechanisms underpin differences in umami perception, which could significantly influence dietary preferences and nutritional outcomes, highlighting the intricate interplay of genetic, physiological, and metabolic factors in taste sensitivity.

A smart thermoresponsive macroporous 4D structure by 4D printing of Pickering-high internal phase emulsions stabilized by plasma-functionalized starch nanomaterials for a possible delivery system.

Hierarchically porous structures combine microporosity, mesoporosity, and microporosity to enhance pore accessibility and transport, which are crucial to develop high performance materials for biofabrication, food, and pharmaceutical applications. This work aimed to develop a 4D-printed smart hierarchical macroporous structure through 3D printing of Pickering-type high internal phase emulsions (Pickering-HIPEs). The key was the utilization of surface-active (hydroxybutylated) starch nanomaterials, including starch nanocrystals (SNCs) (from waxy maize starch through acid hydrolysis) or starch nanoparticles (SNPs) (obtained through an ultrasound treatment). An innovative procedure to fabricate the functionalized starch nanomaterials was accomplished by grafting 1,2-butene oxide using a cold plasma technique to enhance their surface hydrophobicity, improving their aggregation, and thus attaining a colloidally stabilized Pickering-HIPEs with a low concentration of each surface-active starch nanomaterial. A flocculation of droplets in Pickering-HIPEs was developed after the addition of modified SNCs or SNPs, leading to the formation of a gel-like structure. The 3D printing of these Pickering-HIPEs developed a highly interconnected large pore structure, possessing a self-assembly property with thermoresponsive behavior. As a potential drug delivery system, this thermoresponsive macroporous 3D structure offered a lower critical solution temperature (LCST)-type phase transition at body temperature, which can be used in the field of smart releasing of bioactive compounds.
