T cell interactions with microglia in immune-inflammatory processes of ischemic stroke.

The primary mechanism of secondary injury after cerebral ischemia may be the brain inflammation that emerges after an ischemic stroke, which promotes neuronal death and inhibits nerve tissue regeneration. As the first immune cells to be activated after an ischemic stroke, microglia play an important immunomodulatory role in the progression of the condition. After an ischemic stroke, peripheral blood immune cells (mainly T cells) are recruited to the central nervous system by chemokines secreted by immune cells in the brain, where they interact with central nervous system cells (mainly microglia) to trigger a secondary neuroimmune response. This review summarizes the interactions between T cells and microglia in the immune-inflammatory processes of ischemic stroke. We found that, during ischemic stroke, T cells and microglia demonstrate a more pronounced synergistic effect. Th1, Th17, and M1 microglia can co-secrete pro-inflammatory factors, such as interferon-γ, tumor necrosis factor-α, and interleukin-1ß, to promote neuroinflammation and exacerbate brain injury. Th2, Treg, and M2 microglia jointly secrete anti-inflammatory factors, such as interleukin-4, interleukin-10, and transforming growth factor-ß, to inhibit the progression of neuroinflammation, as well as growth factors such as brain-derived neurotrophic factor to promote nerve regeneration and repair brain injury. Immune interactions between microglia and T cells influence the direction of the subsequent neuroinflammation, which in turn determines the prognosis of ischemic stroke patients. Clinical trials have been conducted on the ways to modulate the interactions between T cells and microglia toward anti-inflammatory communication using the immunosuppressant fingolimod or overdosing with Treg cells to promote neural tissue repair and reduce the damage caused by ischemic stroke. However, such studies have been relatively infrequent, and clinical experience is still insufficient. In summary, in ischemic stroke, T cell subsets and activated microglia act synergistically to regulate inflammatory progression, mainly by secreting inflammatory factors. In the future, a key research direction for ischemic stroke treatment could be rooted in the enhancement of anti-inflammatory factor secretion by promoting the generation of Th2 and Treg cells, along with the activation of M2-type microglia. These approaches may alleviate neuroinflammation and facilitate the repair of neural tissues.

Seasonal variations and sensory profiles of oolong tea: Insights from metabolic analysis of Tieguanyin cultivar.

The impact of seasonal variations on the quality of oolong tea products remains a subject of ongoing exploration. This study delves into the intricate relationships between seasonality, metabolites, and sensory characteristics in finished oolong tea products. Metabolomic data from 266 Tieguanyin oolong tea products harvested in both spring and autumn, along with corresponding sensory evaluations, were acquired. Using OPLS-DA and PLS-DA models with UPLC-QToF/MS data, our findings showed that seasonal effects were notably more pronounced in light-scented Tieguanyin products (lightly-roasted) compared to strong-scented products (moderately-roasted). Furthermore, over half of the identified key seasonal discriminant metabolites happened to be crucial for determining the sensory grade. The study marks the first-time recognition of triterpene saponins as critical factors in determining both the harvest season and the sensory grade of oolong tea. These insights deepen our understanding of the interplays between seasonal variations, metabolites, and sensory attributes in oolong tea products.

Land use dynamics and ecosystem service valuation in the Sanmenxia Reservoir wetland of the Yellow River.

The Sanmenxia Reservoir wetland (SRW) serves as a critical ecological buffer in the middle reaches of the Yellow River. Ongoing population growth and changes in land use have placed significant pressure on the wetland's ecosystems. However, existing research has yet to establish a spatiotemporal analysis method to assess the impact of land use change on the ecosystem service value (ESV). This gap hinders the precise regulation and sustainable development of land resources. To gain a comprehensive understanding of the land use dynamics and ecological functions of the SRW, this study introduced a refined ESV evaluation method. This method revised the equivalent factors from spatial, temporal, and hydrological perspectives, with an emphasis on the impact of sediment discharge. Furthermore, the Patch-level Land Use Simulation (PLUS) model was employed to project the land use structure in 2030, and the corresponding ESV was analyzed. The study revealed the following: (1) Cropland constituted the primary land type in the SRW. Over the last two decades, the build-up area exhibited the most significant single land use dynamics, with the transformation of bare land to cropland spanning the widest range and largest area. (2) From 2000 to 2020, the ESV increased by 0.64 billion CNY, with the water body contributing almost all the increase. (3) The projected ESV for 2030 is 2.94 billion CNY, indicating an increase in ecological functions in the near future. Policy makers should recognizethe impact of land use change on ESV and implement measures to rebalance land use structure. While ensuring the preservation of cropland and the protection of lives and property, it is advisable to consider expanding the water body area to facilitate comprehensive sustainable development within SRW.

Proanthocyanidins modification of the mineralized collagen scaffold based on synchronous self-assembly/mineralization for bone regeneration.

Proteoglycans (PG) is crucial for regulating collagen formation and mineralization during bone tissue development. A wide variety of PG-modified collagen scaffolds have been proposed for bone engineering application to promote biological responses and work as artificial matrices that guide tissue regeneration. However, poor performance of theses biomaterials against infections has led to an unmet need for clinical prevention. Therefore, we utilized proanthocyanidins (PA) to simulate the functions of PG, including mediating the collagen assembly and intrafibrillar mineralization, to optimize scaffolds performance. The excellent antibacterial properties of PA can endow the scaffolds with anti-infection effects in the process of tissue regeneration. When PA was added during fibrillogenesis, the collagen fibrils appeared irregular aggregation and the mineralization degree was reduced. In contrast, the addition of PA after collagen self-assembly improved the latter's ability to act as a deposition template and remarkably promoted mineral ions infiltration, thus enhancing intrafibrillar mineralization. The PA-modified scaffold displayed a highly hydrophilicity behaviour and long-term resistance to degradation. The sustained release of PA effectively inhibited the activity of Staphylococcus aureus. The scaffold also showed excellent biocompatibility and improved bone regeneration in calvarial critical-size defect models. The application of PA enables a dual-function scaffold with favourable intrafibrillar mineralization and anti-bacterial properties for bone regeneration.

The Burden of Health Care Utilization, Cost, and Mortality Associated with Select Surgical Site Infections.

OBJECTIVE: To assess the additional health care utilization, cost, and mortality resulting from three surgical site infections (SSIs): mediastinitis/SSI after coronary artery bypass graft, SSI after bariatric surgery for obesity, and SSI after certain orthopedic procedures. METHODS: This retrospective observational cohort study used commercial and Medicare Advantage/Supplement claims from 2016 to 2021. Patients with one of three SSIs were compared to a 1:1 propensity score-matched group of patients with the same surgeries but without SSI on outcomes up to one year postdischarge. RESULTS: The total sample size was 4,620. Compared to their matched cohorts, the three SSI cohorts had longer mean index inpatient length of stay (LOS; adjusted days difference ranged from 1.73 to 6.27 days, all p < 0.001) and higher 30-day readmission rates (adjusted odds ratio ranged from 2.83 to 25.07, all p ≤ 0.001). The SSI cohort for orthopedic procedures had higher 12-month mortality (hazard ratio 1.56, p = 0.01), though other cohorts did not have significant differences. Total medical costs were higher in all three SSI cohorts vs. matched comparison cohorts for the index episode and 6 months and 1 year postdischarge. Average adjusted 1-year total medical cost differences ranged from $40,606 to $68,101 per person, depending on the cohort (p < 0.001), with out-of-pocket cost differences ranging from $330 to $860 (p < 0.05). CONCLUSION: Patients with SSIs experienced higher LOS, readmission rates, and total medical costs, and higher mortality for some populations, compared to their matched comparison cohorts during the first year postdischarge. Identifying strategies to reduce SSIs is important both for patient outcomes and affordability of care.

Stretching vibration driven adiabatic transfer kinetics for photoexcited hole transfer from semiconductor to adsorbate.

Interfacial hole transfer from a photoexcited semiconductor to surface adsorbates is pivotal for initiating solar-to-chemical energy conversion, yet the atomic-level transfer kinetics remains elusive. Using the methoxy/TiO2(110) system as an archetype, here we elucidate the hole transfer mechanism from hole-trapping lattice oxygen to the methoxy adsorbate at gas/solid and liquid/solid interfaces through molecular dynamics simulations and static minimum energy path calculations. Instead of direct nonadiabatic hopping, we uncover an adiabatic migration pathway adapted to local substrate relaxation, driven by a bond-stretching mechanism supported by stronger Ti-O stretching vibrations. Notably, this mechanism persists at the aqueous methoxy/TiO2(110) interface, albeit hindered by interfacial water and coadsorbates. Surprisingly, the hole transfer barriers across various photoexcited adsorbate/TiO2 interfaces correlate more closely with the vertical excitation energies of the adsorbates rather than their redox potentials, indicating an early-type transition-state nature. These insights deepen our understanding of elementary hole transfer kinetics in surface photochemistry.

Acute promyelocytic leukemia: A rare presentation without systemic disease.

Acute promyelocytic leukemia (APL) is a subtype of acute myeloid leukemia characterized by an abnormal proliferation of promyelocytes. It is often associated with an aggressive clinical presentation involving complex coagulopathies including disseminated intravascular coagulation, with a significant risk of bleeding and/or thrombosis if treatment with all-trans-retinoic acid (ATRA) is not rapidly initiated. Here we present a unique case of APL which was isolated to femoral bone lesions, without definitive evidence of peripheral blood or bone marrow involvement, and without systemic sequelae.

Computed tomography-based multi-organ radiomics nomogram model for predicting the risk of esophagogastric variceal bleeding in cirrhosis.

BACKGROUND: Radiomics has been used in the diagnosis of cirrhosis and prediction of its associated complications. However, most current studies predict the risk of esophageal variceal bleeding (EVB) based on image features at a single level, which results in incomplete data. Few studies have explored the use of global multi-organ radiomics for non-invasive prediction of EVB secondary to cirrhosis. AIM: To develop a model based on clinical and multi-organ radiomic features to predict the risk of first-instance secondary EVB in patients with cirrhosis. METHODS: In this study, 208 patients with cirrhosis were retrospectively evaluated and randomly split into training (n = 145) and validation (n = 63) cohorts. Three areas were chosen as regions of interest for extraction of multi-organ radiomic features: The whole liver, whole spleen, and lower esophagus-gastric fundus region. In the training cohort, radiomic score (Rad-score) was created by screening radiomic features using the inter-observer and intra-observer correlation coefficients and the least absolute shrinkage and selection operator method. Independent clinical risk factors were selected using multivariate logistic regression analyses. The radiomic features and clinical risk variables were combined to create a new radiomics-clinical model (RC model). The established models were validated using the validation cohort. RESULTS: The RC model yielded the best predictive performance and accurately predicted the EVB risk of patients with cirrhosis. Ascites, portal vein thrombosis, and plasma prothrombin time were identified as independent clinical risk factors. The area under the receiver operating characteristic curve (AUC) values for the RC model, Rad-score (liver + spleen + esophagus), Rad-score (liver), Rad-score (spleen), Rad-score (esophagus), and clinical model in the training cohort were 0.951, 0.930, 0.801, 0.831, 0.864, and 0.727, respectively. The corresponding AUC values in the validation cohort were 0.930, 0.886, 0.763, 0.792, 0.857, and 0.692. CONCLUSION: In patients with cirrhosis, combined multi-organ radiomics and clinical model can be used to non-invasively predict the probability of the first secondary EVB.

This can promote the improvement of medical services, optimize doctor-patient communication, strengthen patient information support, and optimize the content of online health communities.

Clustered ultra-small iron oxide nanoparticles as potential T1/T2dual-modal magnetic resonance imaging contrast agents and application to tumor model.

Many studies have been conducted on the use of ultra-small iron oxide nanoparticles (USIONs) (d < 3 nm) as potential positive magnetic resonance imaging (MRI)-contrast agents (CAs); however, there is dearth of research on clustered USIONs. In this study, nearly monodispersed clustered USIONs were synthesized using a simple two-step one-pot polyol method. First, USIONs (d = 2.7 nm) were synthesized, and clustered USIONs (d = 27.9 nm) were subsequently synthesized through multiple cross-linking of USIONs with poly(acrylic acid-co-maleic acid) (PAAMA) polymers with many -COOH groups. The clustered PAAMA-USIONs exhibited very weak ferromagnetism owing to the magnetic interaction between superparamagnetic USIONs; this was evidenced by their appreciable r1= 3.9 s‒1mM‒1and high r2/r1ratio of 14.6. Their ability to function as a dual-modal T1/T2MRI-CA in T1-weighted MRI was demonstrated when they simultaneously exhibited positive and negative contrasts in T1-weighted MRI of tumor model mice after intravenous injection. They displayed positive contrasts at the kidneys, bladder, heart, and aorta and negative contrasts at the liver and tumor. .

TianTan Vaccinia Virus-based EBV vaccines targeting both latent and lytic antigens elicits potent immunity against lethal EBV challenge in humanized mice.

AbstractEpstein-Barr virus (EBV) infection has been related to multiple epithelial cancers and lymphomas. Current efforts in developing a prophylactic EBV vaccine have focused on inducing neutralizing antibodies. However, given the lifelong and persistent nature of EBV infection following primary infection, it is rationalized that an ideal vaccine should elicit both humoral and cellular immune responses targeting multiple stages of the EBV lifecycle. This study used a DNA vector and a TianTan vaccinia virus to express key EBV antigens, including BZLF1, EBNA1, EBNA3B, and gH/gL, to generate multi-antigen vaccines. The multi-antigen vaccine expressing all four antigens and the multi-antigen vaccine expressing BZLF1, EBNA1, and EBNA3B showed comparable protection effects and prevented 100% and 80% of humanized mice, respectively, from EBV-induced fatal B cell lymphoma by activating BZLF1, EBNA1, and EBNA3B specific T cell. The vaccine expressing lytic protein BZLF1 elicited stronger T cell responses and conferred superior protection compared to vaccines targeting single latent EBNA1 or EBNA3B. The vaccine solely expressing gH/gL exhibited no T cell protective effects in our humanized mice model. Our study implicates the potential of EBV vaccines that induce potent cellular responses targeting both latent and lytic phases of the EBV life cycle in the prevention of EBV-induced B cell lymphoma.

Diagnosis and Analysis of Vasa Previa Types With Flow HD Glass Body.

OBJECTIVES: To explore the value of applying flow high definition (HD) glass body in prenatal diagnosis of vasa previa and to preliminarily discuss the types of vasa previa. METHODS: Two-dimensional ultrasound, flow HD, and flow HD glass body were used to image the umbilical cord insertion site and placenta, observe the cervical internal os and surrounding areas, and retrospectively analyze cases of vasa previa. RESULTS: There were 15 cases of vasa previa, including 14 cases of singleton pregnancies and 1 case of twin pregnancy, with a total of 22 vasa previa, including 10 veins and 12 arteries. There was 1 case with 3 vessels, 5 cases with 2 vessels, and 9 cases with a single vessel. Among them, in 3 cases of vasa previa detected at 12, 14, and 24 weeks, respectively, the vasa previa were relocated to a normal position at 24, 29, and 35 weeks of gestation when re-examined. Routine 2-dimensional ultrasound examination in this group showed tubular or circular hypoechoic areas near the cervical internal os, but vasa previa could not be confirmed. Flow HD could display color blood flow at and near the cervical internal os in 15 cases, but it was difficult to continuously show the course and source of the blood vessels under the chorion. Flow HD glass body from multiple angles could display the relationship between 15 cases of 22 vasa previa and the placenta and cervix. Combined with color Doppler blood flow spectra, flow HD glass body could determine the types of vasa previa. CONCLUSIONS: Flow HD glass body imaging can clearly display vasa previa, showing their origin and the spatial relationship with the cervix and placenta in a 3-dimensional manner, displaying the course and attachment points of umbilical vessels under the chorion. It can observe the area of interest at any angle, and combined with color Doppler blood flow spectra, it can judge the vasa previa of the umbilical vein, providing a more definite imaging basis for clinical management.

Design, Synthesis, and Biological Evaluation of Novel Quinoline Derivatives against Phytopathogenic Bacteria Inspired from Natural Quinine Alkaloids.

A series of 2-(trifluoromethyl)-4-hydroxyquinoline derivatives were designed and synthesized with introduction of the antibacterial fragment amino alcohols, and their antibacterial activity against plant phytopathogenic bacteria was evaluated for the development of quinoline bactericides. It is worth noting that compound Qa5 exhibited excellent antibacterial activity in vitro with a minimum inhibitory concentration (MIC) value of 3.12 µg/mL against Xanthomonas oryzae (Xoo). Furthermore, in vivo assays demonstrated that the protective efficacy of Qa5 against rice bacterial blight at 200 µg/mL (33.0%) was superior to that of the commercial agent bismerthiazol (18.3%), while the curative efficacy (35.0%) was comparable to that of bismerthiazol (35.7%). The antibacterial mechanisms of Qa5 indicated that it affected the activity of bacteria by inducing intracellular oxidative damage in Xoo and disrupting the integrity of the bacterial cell membrane. The above results demonstrated that the novel quinoline derivative Qa5 possessed excellent in vitro and in vivo antibacterial activity, indicating its potential as a novel green agricultural antibacterial agent.

The Role of Human Adiponectin Receptor 1 in 2-Ethylhexyl Diphenyl Phosphate Induced Lipid Metabolic Disruption.

Epidemiological evidence links exposure to 2-ethylhexyl diphenyl phosphate (EHDPP) with lipid metabolic disruption, typically attributed to nuclear receptors, while the role of membrane receptors remains underexplored. This study explored the role of adiponectin receptor 1 (AdipoR1) in EHDPP-induced lipid metabolic disturbances. We examined EHDPP's binding affinity and transcriptional impact on AdipoR1. AdipoR1 knockdown (AdipoR1kd) human liver cells and coculture experiments with AdipoR1 activator (AdipoRon) were used to investigate the effect and the mechanism. EHDPP disrupted triglyceride and phospholipid synthesis and altered corresponding gene expression, mirroring effects in AdipoR1kd cells but diminishing in EHDPP-treated AdipoR1kd cells. RNA sequencing revealed that EHDPP primarily disrupted oxidative phosphorylation and insulin signaling dependent on AdipoR1. Mechanistically, EHDPP interacted with AdipoR1 and reduced AdipoR1 protein levels at 10-7 mol/L or higher, weakening the activation of the calmodulin dependent protein kinase ß (CaMKKß)/AMPK/acetyl CoA carboxylase pathway. Furthermore, EHDPP pretreatment blocked the increase in Ca2+ flux and the corresponding kinase CaMKKß, as well as liver kinase B1 (LKB1) activation induced by AdipoRon, which is necessary for AMPK activation. Collectively, these findings demonstrate that EHDPP-induced lipid imbalance is partially dependent on AdipoR1, expanding the understanding of environmental metabolic disruptors beyond nuclear receptors.

Study on the Antidepressant Effect of Zhizichi Decoction by Regulating Metabolism and Intestinal Flora.

BACKGROUND: The incidence of depression is increasing year by year, and Zhizichi Decoction（ZZCD）has shown significant efficiency in the clinical treatment of mild depression, but its mechanism of action is still unclear. In this research, network pharmacology and metagenomics combined and metabolomics were used as research methods to explain the scientific connotation of the antidepressant effect of ZZCD from the aspects of the overall effect of organisms and microbial structure and function. METHODS: The rat model of depression was established by chronic unpredictable mild stress (CUMS), and the improvement of depressive symptoms was evaluated by behavioral and histopathological methods. Network pharmacology predicted possible targets and important pathways of ZZCD. Metabolomics revealed its possible related biological pathways. Metagenomics showed the disturbance of ZZCD on intestinal microbial diversity structure and associated biological functions in depressed rats. RESULTS: ZZCD can improve the behavioral performance of CUMS rats, and can significantly regulate the content of 5-HT, NE and other neurotransmitters in serum and brain tissue, and improve the damaged state of neurons in the hippocampus. Network pharmacology predicts that it mainly acts on biological processes such as inflammatory response and oxidative stress response. Metabolomics found that it affected metabolic pathways such as amino acid metabolism and lipid metabolism. The results of metagenomics showed that it significantly regulated the abundance of Firmicutes and Bacteroidetes. The above results predicted that it may affect signaling pathways such as the nervous system, inflammatory diseases and cell processing. CONCLUSION: ZZCD may play an antidepressant role by regulating intestinal probiotics, energy metabolism, and inflammation reduction. This provides a scientific basis for the clinical application of ZZCD in traditional Chinese medicine and also makes it an optional alternative for the treatment of depression.

Systematic analysis of the ARF gene family in Fagopyrum dibotrys and its potential roles in stress tolerance.

The auxin response factor (ARF) is a plant-specific transcription factor that regulates the expression of auxin response genes by binding directly to their promoters. They play an important role in the regulation of plant growth and development, as well as in the response to biotic and abiotic stresses. However, the identification and functional analysis of ARFs in Fagopyrum dibotrys are still unclear. In this study, a total of 26 FdARF genes were identified using bioinformatic methods. Their chromosomal location, gene structure, physical and chemical properties of their encoded protein, subcellular location, phylogenetic tree, conserved motifs and cis-acting elements in FdARF promoters were analyzed. The results showed that 26 FdARF genes were unevenly distributed on 8 chromosomes, with the largest distribution on chromosome 4 and the least distribution on chromosome 3. Most FdARF proteins are located in the nucleus, except for the proteins FdARF7 and FdARF21 located to the cytoplasm and nucleus, while FdARF14, FdARF16, and FdARF25 proteins are located outside the chloroplast and nucleus. According to phylogenetic analysis, 26 FdARF genes were divided into 6 subgroups. Duplication analysis indicates that the expansion of the FdARF gene family was derived from segmental duplication rather than tandem duplication. The prediction based on cis-elements of the promoter showed that 26 FdARF genes were rich in multiple stress response elements, suggesting that FdARFs may be involved in the response to abiotic stress. Expression profiling analysis showed that most of the FdARF genes were expressed in the roots, stems, leaves, and tubers of F. dibotrys, but their expression exhibits a certain degree of tissue specificity. qRT-PCR analysis revealed that most members of the FdARF gene were up- or down-regulated in response to abiotic stress. The results of this study expand our understanding of the functional role of FdARFs in response to abiotic stress and lay a theoretical foundation for further exploration of other functions of FdARF genes.

A germline-to-soma signal triggers an age-related decline of mitochondrial stress response.

The abilities of an organism to cope with extrinsic stresses and activate cellular stress responses decline during aging. The signals that modulate stress responses in aged animals remain to be elucidated. Here, we discover that feeding Caenorhabditis elegans (C. elegans) embryo lysates to adult worms enabled the animals to activate the mitochondrial unfolded protein response (UPRmt) upon mitochondrial perturbations. This discovery led to subsequent investigations that unveil a hedgehog-like signal that is transmitted from the germline to the soma in adults to inhibit UPRmt in somatic tissues. Additionally, we find that the levels of germline-expressed piRNAs in adult animals markedly decreased. This reduction in piRNA levels coincides with the production and secretion of a hedgehog-like signal and suppression of the UPRmt in somatic cells. Building upon existing research, our study further elucidates the intricate mechanisms of germline-to-soma signaling and its role in modulating the trade-offs between reproduction and somatic maintenance within the context of organismal aging.

Association between parental educational involvement and adolescent depressive symptoms: a systematic review and meta-analysis.

BACKGROUND: Adolescents in their school-age period undergo rapid changes in various aspects, such as physiological development, academic pressure, and interpersonal relationships, constitute a high-risk group for depression. Parental educational involvement, as a critical family variable, influences not only children's academic achievement but also their psychological well-being. However, previous research has shown significant discrepancies regarding the relationship between parental educational involvement and adolescent depressive symptoms. METHODS: To elucidate the overall strength of the association between parental educational involvement and adolescent depressive symptoms, this study systematically searched Web of Science, Medline, PubMed, CNKI, and other Chinese and English databases. A meta-analysis was conducted on 22 selected studies encompassing 36 effect sizes and involving 390,094 participants. RESULTS: The results revealed a moderate negative correlation between parental educational involvement and adolescent depressive symptoms (r = -0.200, 95% CI [-0.26, -0.14]). Additionally, the relationship between parental educational involvement and adolescent depressive symptoms was found to be moderated by factors such as adolescent age, grade level and the reporter of parental educational involvement. However, it was not influenced by the female ratio or cultural background. CONCLUSIONS: This study offers the inaugural comprehensive assessment of the relationship between parental educational involvement and adolescent depressive symptoms, with variations observed across different ages, grade levels, and reporter of parental educational involvement.

Link Between Obstructive Sleep Apnea and Kidney Stones: NHANES 2015-2018 and Mendelian Randomization.

Purpose: The prevalence of Obstructive Sleep Apnea (OSA) is high, and there are many complications. Few studies have reported the relationship between OSA and kidney stones. The purpose of this study is to explore whether people at risk of OSA will increase the risk of kidney stones. Methods: This was a cross-sectional study, and information was collected through the National Health and Nutrition Examination Survey conducted from 2015 to 2018. Multiple logistic regression analyses were employed to calculate the odds ratios (ORs) and their 95% confidence intervals (CIs) for the link between obstructive sleep apnea and the presence of kidney stones. Additionally, to assess causality and reduce observational biases, five distinct two-sample Mendelian randomization techniques were applied. Results: Following the adjustment for relevant confounders, findings indicated a statistically significant correlation between obstructive sleep apnea (OSA) and higher prevalence of kidney stones (OR = 1.29; 95% CI: 1.00-1.66). Additionally, using the inverse-variance weighted approach in Mendelian randomization, results suggested a genetic predisposition to OSA might be causally linked to an elevated risk of developing kidney stones (OR: 1.00221, 95% CI 1.00056-1.00387). Conclusion: OSA promotes the formation of kidney stones, and the treatment and management of OSA can improve or mitigate the occurrence of kidney stones.

Effective pretreatment of microwave combined with acetic acid soaking on oil absorption and quality of fried potato chips.

BACKGROUND: This study applied a combined pretreatment method involving microwave and acetic acid (AA) soaking to monitor oil absorption of fried potato chips based on texture and microstructure characteristics. RESULTS: Results demonstrated that medium-low microwave combined with 4 h of AA soaking significantly improved the texture profile of potato chips, and reduced oil content by approximately 53.25%. Higher microwave intensity led to greater surface roughness of samples, whereas AA soaking for 1-4 h effectively reduced surface roughness. The decrease in Fm and Nwr, along with the increase in Fwr and Wc with prolonged AA soaking time for 1-4 h indicated that medium-low microwave intensity combined with AA pretreatment enhanced hardness and brittleness of samples. Microscopic examination of cell structure revealed that this combined pretreatment facilitated pectin gelation between the cell walls of potato chips, resulting in a more intact cell structure with fewer gaps. Additionally, the color of pretreated potato chips became brighter. CONCLUSION: The combination of medium-low microwave intensity and AA soaking pretreatment resulted in a decrease in the oil content and improved the texture profile of fried potato chips. This study provides new strategies and insights for producing low-fat potato chips based on low-cost pretreatment. © 2024 Society of Chemical Industry.
