RESUMEN

BACKGROUND & AIMS: Low plasma B12 and folate levels or hyperhomocysteinemia are related to cognitive impairment. This study explores the relationships among diet pattern, blood folate-B12-homocysteine levels, and cognition measurement in Alzheimer's disease (AD) while exploring whether a gender effect may exist. METHODS: This cross-sectional study enrolled 592 AD patients (246 males, 346 females) and the demographic data, blood biochemical profiles, Mini-Mental State Examination (MMSE), and a Food Frequency Questionnaire (FFQ) for quantitative assessment of dietary frequency were collected. Structural Equation Modeling (SEM) was employed to explore the associations among dietary patterns, blood profiles, and cognition. A least absolute shrinkage and selection operator regression model, stratified by gender, was constructed to analyze the weighting of possible confounders. RESULTS: Higher MMSE scores were related to higher frequencies of coffee/tea and higher educational levels, body mass index, and younger age. The SEM model revealed a direct influence of dietary frequencies (skimmed milk, thin pork, coffee/tea) and blood profiles (homocysteine, B12, and folate) on cognitive outcomes. At the same time, the influence of dietary pattern on cognition was not mediated by folate-B12-homocysteine levels. In males, a direct influence on the MMSE is attributed to B12, while in females, homocysteine is considered a more critical factor. CONCLUSIONS: Dietary patterns and blood profiles are both associated with cognitive domains in AD, and there are gender differences in the associations of dietary patterns and the levels of B12 and homocysteine. To enhance the quality of dietary care and nutritional status for individuals with dementia, our study results still require future validations with multi-center and longitudinal studies.

RESUMEN

Colorectal cancer (CRC) is one of the most common cancers and is the second leading cause of cancer-related death in the world. Due to the westernization of diets, young patients with CRC are often diagnosed at advanced stages with an associated poor prognosis. Improved lifestyle choices are one way to minimize CRC risk. Among diet choices is the inclusion of bee propolis, long recognized as a health supplement with anticancer activities. Understanding the effect of propolis on the gut environment is worth exploring, and especially its associated intratumoral immune changes and its anticancer effect on the occurrence and development of CRC. In this study, early stage CRC was induced with 1,2-dimethylhydrazine (DMH) and dextran sulfate sodium (DSS) for one month in an animal model, without and with propolis administration. The phenotypes of early stage CRC were evaluated by X-ray microcomputed tomography and histologic examination. The gut immunity of the tumor microenvironment was assessed by immunohistochemical staining for tumor-infiltrating lymphocytes (TILs) and further comparative quantification. We found that the characteristics of the CRC mice, including the body weight, tumor loading, and tumor dimensions, were significantly changed due to propolis administration. With further propolis administration, the CRC tissues of DMH/DSS-treated mice showed decreased cytokeratin 20 levels, a marker for intestinal epithelium differentiation. Additionally, the signal intensity and density of CD3+ and CD4+ TILs were significantly increased and fewer forkhead box protein P3 (FOXP3) lymphocytes were observed in the lamina propria. In conclusion, we found that propolis, a natural supplement, potentially prevented CRC progression by increasing CD3+ and CD4+ TILs and reducing FOXP3 lymphocytes in the tumor microenvironment of early stage CRC. Our study could suggest a promising role for propolis in complementary medicine as a food supplement to decrease or prevent CRC progression.

RESUMEN

B vitamins play a crucial role in maintaining fundamental cellular functions and various essential metabolic pathways in the body. Although they do not directly provide energy, each B vitamin acts as a cofactor in energy metabolism processes. Based on the evidence presented above, we hypothesized that a 28-day supplementation of vitamin B would enhance physical performance and reduce physical fatigue. The objective of this study was to evaluate the anti-fatigue effect of vitamin B supplementation, specifically vitamin B1, B2, B6, and B12, and its potential to improve exercise performance. We employed a randomized double-blind crossover design with a 28-day supplementation period. Sixteen male and sixteen female subjects, aged 20-30 years, were divided into two groups: the placebo group (n=16, equal gender distribution) and the Ex PLUS® group (n=16, equal gender distribution). The participants received either placebo or Ex PLUS® (one tablet per day) for 28 consecutive days. Following the intervention, there was a 14-day wash-out period during which the subjects did not receive any further interventions. After supplementation with Ex PLUS®, we found a significant increase in the running time by 1.26-fold (p < 0.05) to exhaustion compared to that before supplementation and that in the placebo group. In addition, the Ex PLUS® supplementation group presented significantly reduced blood lactate and blood ammonia concentrations during exercise and at rest after exercise compared with placebo (p < 0.05). In conclusion, 28 consecutive days of vitamin B complex (Ex PLUS®) supplementation significantly improved exercise endurance performance and reduced exercise fatigue biochemical metabolites in not athletes. In addition, it does not cause adverse effects in humans when taken at appropriate doses.

RESUMEN

Advanced bladder cancer is still an area of high unmet need even with the use of immune checkpoint inhibitors and antibody drug conjugates. Therefore, transformatively novel therapeutic approaches are needed. Xenogeneic cells are capable of inducing potent innate and adaptive immune rejection responses, which properties could turn xenogeneic cells into an immunotherapeutic agent. Here, we investigated the anti-tumor effects of intratumoral xenogeneic urothelial cell (XUC) immunotherapy alone and in combination with chemotherapy in two murine syngeneic models of bladder cancer. In both bladder tumor models, intratumoral XUC treatment suppressed tumor growth, and the efficacy was enhanced with chemotherapy. The experiments on mode of action for intratumoral XUC treatment found that the remarkable local and systemic anti-tumor effects were achieved with significant intratumoral immune cell infiltration and systemic activation of immune cell cytotoxic activity, cytokine IFNγ production and proliferation ability. The intratumoral XUC alone and combined treatment increased T cell natural killer cell infiltration into tumors. In the bilateral tumor model with intratumoral XUC monotherapy or combined therapy, the uninjected tumors at the other side also simultaneously demonstrated significant tumor growth delay. Consequently, intratumoral XUC treatment alone and the combination resulted in elevated chemokine CXCL9/10/11 levels. These data suggest that intratumoral XUC therapy may be useful in the treatment of advanced bladder cancer as a local therapy that injects xenogeneic cells into either primary or distant tumors. By exerting both local and systemic anti-tumor effects, this new treatment would complete the comprehensive cancer management along with systemic approaches.

RESUMEN

Head and neck cancer is a major cancer type, with high motility rates that reduce the quality of life of patients. Herein, we investigated the effectiveness and mechanism of a combination therapy involving TLR9 activator (CpG-2722) and phosphatidylserine (PS)-targeting prodrug of SN38 (BPRDP056) in a syngeneic orthotopic head and neck cancer animal model. The results showed a cooperative antitumor effect of CpG-2722 and BPRDP056 owing to their distinct and complementary antitumor functions. CpG-2722 induced antitumor immune responses, including dendritic cell maturation, cytokine production, and immune cell accumulation in tumors, whereas BPRDP056 directly exerted cytotoxicity toward cancer cells. We also discovered a novel function and mechanism of TLR9 activation, which increased PS exposure on cancer cells, thereby attracting more BPRDP056 to the tumor site for cancer cell killing. Killed cells expose more PS in tumor for BPRDP056 targeting. Tumor antigens released from the dead cells were taken up by antigen-presenting cells, which enhanced the CpG-272-promoted T cell-mediated tumor-killing effect. These form a positive feed-forward antitumor effect between the actions of CpG-2722 and BPRDP056. Thus, the study findings suggest a novel strategy of utilizing the PS-inducing function of TLR9 agonists to develop combinational cancer treatments using PS-targeting drugs.

RESUMEN

BACKGROUND: Preterm complications are now the second leading cause of death in children under five years of age. Colostrum is essential to prevent infection and promote maturation in preterm infants. Guidelines recommend that preterm infants be fed colostrum by the oral and pharyngeal routes as early as possible after birth to provide immune protection; however, due to disease and an uncoordinated sucking and swallowing function, it is challenging to provide colostrum through the oropharyngeal route, which limits the immune protection it provides. OBJECTIVE: To update the existing meta-analysis, evaluate the effect of oropharyngeal colostrum administration on related outcomes in preterm infants and explore the optimal frequency and duration of oropharyngeal colostrum administration through subgroup analysis. METHODS: The Cochrane Library, PubMed, Web of Science, ScienceDirect, and Ovid databases were searched for randomized control trials (RCTs) of oropharyngeal colostrum administration for preterm infants. Two researchers screened the literature strictly according to the inclusion and exclusion criteria and evaluated the quality. Primary data and data from the included literature were extracted. Finally, the data were statistically analyzed by the Review Manager 5.3 software. RESULTS: A total of 1736 preterm infants were included in 16 RCTs. The meta-analysis showed that the incidence of necrotizing enterocolitis, late-onset sepsis, feeding intolerance, and death was lower, the time to full enteral feeding was shorter, and the day of recovery to birth weight was earlier in the intervention group (oropharyngeal colostrum administration group) than in the control group, and this difference was statistically significant. Subgroup analysis: Frequency of oropharyngeal colostrum administration: The incidence of necrotizing enterocolitis and late-onset sepsis in the once every 4 h group was lower than that in the control group, and the time to complete enteral feeding was shorter. Duration of oropharyngeal colostrum administration: In the 1-3 days group and 4-7 days group, the time to full enteral feeding in the intervention group was shorter. In the 8-10 days group, the incidence of necrotizing enterocolitis and late-onset sepsis was lower in the intervention group. CONCLUSIONS: Oropharyngeal colostrum administration can reduce the incidence of necrotizing enterocolitis, late-onset sepsis, feeding intolerance and mortality, shorten the time to full enteral feeding, and lead to a faster recovery to birth weight in preterm infants. The appropriate oropharyngeal colostrum administration frequency may be 4 h, and the optimal duration may be 8-10 days. Therefore, it is recommended that clinical medical staff implement oropharyngeal colostrum administration for premature infants based on existing evidence. TWEETABLE ABSTRACT: Oropharyngeal colostrum administration can reduce the incidence of complications in preterm infants and shorten the time to full enteral feeding.

RESUMEN

BACKGROUND: Retinoblastoma, the most common pediatric intraocular malignancy, can develop during embryogenesis, with most children being diagnosed at 3-4 years of age. Multimodal therapies are typically associated with high levels of cytotoxicity and side effects. Therefore, the development of novel treatments with minimal side effects is crucial. Magnolol has a significant anti-tumor effect on various cancers. However, its antitumor effect on retinoblastoma remains unclear. PURPOSE: The study aimed to determine the effects of magnolol on the regulation of EMT, migration, invasion, and cancer progression in retinoblastoma and the modulation of miR-200c-3p expression and the Wnt/ zinc finger E-box binding homeobox 1 (ZEB1)/E-cadherin axis in vivo and in vitro. METHODS: The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) (MTT) assay was used to evaluate magnolol-induced cell toxicity in the Y79 retinoblastoma cell line. Flow cytometry and immunostaining assays were performed to investigate the magnolol-regulated mitochondrial membrane potential and the intracellular and mitochondrial reactive oxygen species levels in Y79 retinoblastoma cells. Orthotopic and subcutaneous xenograft experiments were performed in eight-week-old male null mice to study retinoblastoma progression and metastasis. In situ hybridization and quantitative reverse transcription polymerase chain reaction (RT-qPCR) assays were performed to evaluate the level of the anti-cancer miRNA miR-200c-3p. The mRNA and protein levels of E-cadherin, ß-catenin, α-smooth muscle actin (α-SMA), fibronectin-1, and ZEB1 were analyzed using RT-qPCR, immunoblot, immunocytochemistry, and immunohistochemistry assays in vitro and in vivo. RESULTS: Magnolol increased E-cadherin levels and reduced the activation of the EMT signaling pathway, EMT, tumor growth, metastasis, and cancer progression in the Y79 retinoblastoma cell line as well as in the orthotopic and subcutaneous xenograft animal models. Furthermore, magnolol increased the expression of miR-200c-3p. Our results demonstrate that miRNA-200c-3p inhibits EMT progression through the Wnt16/ß-catenin/ZEB1/E-cadherin axis, and the ZEB1 silencing response shows that miR-200c-3p regulates ZEB1-mediated EMT in retinoblastoma. CONCLUSION: Magnolol has an antitumor effect by increasing E-cadherin and miRNA-200c-3p expression to regulate ZEB1-mediated EMT and cancer progression in retinoblastoma. The anti-tumor effect of magnolol by increasing E-cadherin and miRNA-200c-3p expression to regulate ZEB1-mediated EMT and cancer progression in retinoblastoma has been elucidated for the first time.

RESUMEN

Dietary pattern (DP) results in nutrition adequacy and may influence cognitive decline and cortical atrophy in Alzheimer's disease (AD). The study explored DP in 248 patients with AD. Two neurobehavioral assessments (intervals 13.4 months) and two cortical thickness measurements derived from magnetic resonance images (intervals 26.5 months) were collected as outcome measures. Reduced rank regression was used to assess the groups of DPs and a linear mixed-effect model to explore the cortical neurodegenerative patterns. At screening, underweight body mass index (BMI) was related to significant higher lipid profile, impaired cognitive function, smaller cortical thickness, lower protein DP factor loading scores and the non-spouse caregiver status. Higher mini-mental state examination (MMSE) scores were related to the DP of coffee/tea, compared to the lipid/sugar or protein DP group. The underweighted-BMI group had faster cortical thickness atrophy in the pregenual and lateral temporal cortex, while the correlations between cortical thickness degeneration and high HbA1C or low B12 and folate levels were localized in the medial and lateral prefrontal cortex. The predictive model suggested that factors related to MMSE score were related to the caregiver status. In conclusion, normal or overweight BMI, coffee/tea DP group and living with a spouse were considered as protective factors for better cognitive outcomes in patients with AD. The influence of glucose, B12 and folate on the cortical degeneration was spatially distinct from the pattern of AD degeneration.

RESUMEN

Gout is a common metabolic disease caused by abnormal purine metabolism that promotes the formation and deposition of monosodium urate crystals within joints that causes acute arthritis and can seriously affect the daily life of patients. Pistacia chinensis is one of the traditional medicinal plants of the Anacardiaceae family, and there have been many studies on its biological activity, including anti-inflammatory, antidepressant, antibacterial, antioxidant, and hypoglycemic activities. The aim of this study was to evaluate the antigout effect of P. chinensis leaf essential oil and its constituents through xanthine oxidase inhibition. Leaf essential oil showed good xanthine oxidase inhibitory activity for both substrates, hypoxanthine and xanthine. Six fractions were obtained from open column chromatography, and fraction E1 exhibited the best activity. The constituents of leaf essential oil and fraction E1 were analyzed by GC-MS. The main constituents of both leaf essential oil and fraction E1 were limonene and 3-carene; limonene showed a higher inhibitory effect on xanthine oxidase. Based on the enzyme kinetic investigation, limonene was the mixed-type inhibitor against xanthine oxidase. The results revealed that Pistacia chinensis leaf essential oil and limonene have the potential to act as natural remedies for the treatment of gout.

RESUMEN

OBJECTIVE: To observe the effects of thunder-fire moxibustion on the visual analogue scale (VAS) score, Young's modulus of multifidus and 6 m walking speed in the patients of osteoporosis with low skeletal muscle mass. METHODS: Sixty patients of osteoporosis with low skeletal muscle mass were randomly divided into a medication group (30 cases) and a medication+thunder-fire moxibustion group (30 cases). In the medication group, caltrate was prescribed for oral administration, 2 tablets/day (600 mg/tablet), for 4 weeks. In the medication+thunder-fire moxibustion group, on the base of oral administration with caltrate, thunder-fire moxibustion was exerted at Mingmen (GV4), Yaoyangguan(GV3), and bilateral Shenshu (BL23), Ganshu (BL18) and Dachangshu (BL25), 30 minutes at GV4, GV3 and BL18, and another 30 minutes at BL23 and BL25, once every other day, 3 times a week for 4 weeks. Before and after the treatment, VAS score, Young's modulus of the 4th lumbar multifidus and the average speed of 6 m walking were assessed. RESULTS: After the treatment, the VAS score was decreased (P<0.05, P<0.01) and the speed of 6 m walking was increased (P<0.05, P<0.01) in both groups in comparison with their own pre-treatment. Compared with the medication group, VAS score was decreased remarkably (P<0.05) and the speed of 6 m walking remarkably increased (P<0.01) in the medication+thunder-fire moxibustion group after the treatment. Self-comparison showed that, compared with the same side before the treatment, the value of Young's modulus after the treatment was decreased on both sides in the medication+thunder-fire moxibustion group (P<0.01). After the treatment, compared with the medication group on the same side, the value of Young's modulus was decreased on both sides (P<0.01) in the medication+thunder-fire moxibustion group. CONCLUSION: Thunder-fire moxibustion can relieve pain intensity, decrease the tension of the multifidus, and increase the walking speed.

RESUMEN

CONTEXT: Zhishi Rhubarb Soup (ZRS) is a traditional Chinese medicine formula used in the clinic to treat acute cerebral infarction (ACI) for many years. However, the exact mechanism of the treatment remains unclear. OBJECTIVE: This study elucidates the multitarget mechanisms underlying the effects of ZRS on ACI using network pharmacology analysis and verify its effect by performing animal experiments. MATERIALS AND METHODS: Using the network pharmacology approach, the multiple components, critical targets and potential mechanisms of ZRS against ACI were investigated. Six herbal names of ZRS and 'acute cerebral infarction' were used as keywords to search the relevant databases. In addition, we established the MCAO model to verify the results of network pharmacology enrichment analysis. ZRS (10 g crude drug/kg) was gavaged once per day for 7 consecutive days beginning 3 h after model establishment. After ZRS treatment, TTC staining, Western blot analysis, IHC and ELISA were conducted to further explore the mechanism of ZRS intervention in ACI. RESULTS: The network pharmacology approach identified 69 key targets, 10 core genes and 169 signalling pathways involved in the treatment of ACI with ZRS. In vivo experiment showed that ZRS treatment significantly reduced cerebral infarction volume (42.76%). It also reduced the expression level of AGE, RAGE and P65; and inhibited the expression of inflammatory MMP-9 and IFN-γ. CONCLUSIONS: This study demonstrated that ZRS improved cerebral ischaemic injury by inhibiting neuroinflammation partly via the AGE-RAGE signalling pathway. It provides a theoretical basis for the clinical application of ZRS in the treatment of ACI.

RESUMEN

Coronavirus disease 2019 (COVID-19) remains a threat with the emergence of new variants, especially Delta and Omicron, without specific effective therapeutic drugs. The infection causes dysregulation of the immune system with a cytokine storm that eventually leads to fatal acute respiratory distress syndrome (ARDS) and further irreversible pulmonary fibrosis. Therefore, the promising way to inhibit infection is to disrupt the binding and fusion between the viral spike and the host ACE2 receptor. A transcriptome-based drug screening platform has been developed for COVID-19 to explore the possibility and potential of the long-established drugs or herbal medicines to reverse the unique genetic signature of COVID-19. In silico analysis showed that Virofree, an herbal medicine, reversed the genetic signature of COVID-19 and ARDS. Biochemical validations showed that Virofree could disrupt the binding of wild-type and Delta-variant spike proteins to ACE2 and its syncytial formation via cell-based pseudo-typed viral assays, as well as suppress binding between several variant recombinant spikes to ACE2, especially Delta and Omicron. Additionally, Virofree elevated miR-148b-5p levels, inhibited the main protease of SARS-CoV-2 (Mpro), and reduced LPS-induced TNF-α release. Virofree also prevented cellular iron accumulation leading to ferroptosis which occurs in SARS-CoV-2 patients. Furthermore, Virofree was able to reduce pulmonary fibrosis-related protein expression levels in vitro. In conclusion, Virofree was repurposed as a potential herbal medicine to combat COVID-19. This study highlights the inhibitory effect of Virofree on the entry of Delta and Omicron variants of SARS-CoV-2, which have not had any effective treatments during the emergence of the new variants spreading.

RESUMEN

A novel electrochemical method has been developed for determination of nitrite using La-based perovskite-type lanthanum aluminate nanorod-incorporated graphene oxide nanosheets (LaAlO3@GO). Morphological and structural analyses of the prepared perovskite-type electrocatalyst, with and without a glassy carbon electrode (GCE) surface, were performed using various techniques, including transmission electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffractometry, Raman spectroscopy, and electrochemical impedance spectroscopy. Under optimal conditions, the LaAlO3@GO composite-modified GCE (LaAlO3@GO/GCE) exhibited excellent electrocatalytic performance toward the electrooxidation of nitrite (pH = 7.0), with a significant increase in anodic peak currents compared with the bare GCE. Using amperometry, the fabricated sensor exhibited a wide nitrite determination range from 0.01 to 1540.5 µM, with a detection limit of 0.0041 µM. Notably, the proposed LaAlO3@GO/GCE electrode demonstrated a good nitrite detection performance in different meat and water samples. In addition, the LaAlO3@GO/GCE electrode displayed excellent selectivity, repeatability, reproducibility, storage, and operational stability toward nitrite detection.

RESUMEN

OBJECTIVES: Benign prostatic hyperplasia affects elderly males, with progression presenting the risk of urinary complications and eventual surgical intervention. We aimed to evaluate the effects of Chinese herbal medicine in patients with benign prostatic hyperplasia. METHODS: This retrospective cohort study analyzed claims data in Taiwan's National Health Insurance Research Database from 2001 to 2013. A total of 4142 patients newly diagnosed as benign prostatic hyperplasia were enrolled and divided into cohorts of Chinese herbal medicine users and nonusers by performing 1:1 propensity score matching. The risk of benign prostatic hyperplasia-related complications was assessed by the Cox proportional hazard model. The cumulative incidence of benign prostatic hyperplasia-related surgeries was assessed by Kaplan-Meier method. RESULTS: During the study period, the risk of benign prostatic hyperplasia-related complications was lower in the Chinese herbal medicine cohort than non-Chinese herbal medicine cohort with an adjusted hazard ratio of 0.82 (95% confidence interval 0.73-0.92) after controlling for multiple variables. Subgroup analysis revealed that Chinese herbal medicine users had a significantly lower risk of urinary tract infection (adjusted hazard ratio 0.67, 95% confidence interval 0.50-0.89) and urinary retention (adjusted hazard ratio 0.83, 95% confidence interval 0.72-0.97). In addition, Chinese herbal medicine users also had a lower incidence rate of benign prostatic hyperplasia-related surgery (32.14 vs 40.20, adjusted hazard ratio 0.74, 95% confidence interval 0.61-0.89) and a longer surgery-free interval than non-Chinese herbal medicine users (3.98 vs 3.00 mean person-year, P < 0.001). Data revealed Salviae miltiorrhizae and Ji-Sheng-Shen-Qi-Wan as the most commonly prescribed Chinese herbal medicine by traditional Chinese medicine practitioners. CONCLUSIONS: Our study demonstrated that Chinese herbal medicine might have effects in the benign prostatic hyperplasia-related complications and surgeries in patients with benign prostatic hyperplasia.

RESUMEN

The chromosome segregation 1­like (CSE1L) protein, which regulates cellular mitosis and apoptosis, was previously found to be overexpressed in colorectal cancer (CRC) cells harboring mutations. Therefore, regulating CSE1L expression may confer chemotherapeutic effects against CRC. The gut microflora can regulate gene expression in colonic cells. In particular, metabolites produced by the gut microflora, including the short­chain fatty acid butyrate, have been shown to reduce CRC risk. Butyrates may exert antioncogenic potential in CRC cells by modulating p53 expression. The present study evaluated the association between CSE1L expression and butyrate treatment from two non­transformed colon cell lines (CCD­18Co and FHC) and six CRC cell lines (LS 174T, HCT116 p53+/+, HCT116 p53­/­, Caco­2, SW480 and SW620). Lentiviral knockdown of CSE1L and p53, reverse transcription­quantitative PCR (CSE1L, c­Myc and p53), western blotting [CSE1L, p53, cyclin (CCN) A2, CCNB2 and CCND1], wound healing assay (cell migration), flow cytometry (cell cycle analysis) and immunofluorescence staining (CSE1L and tubulin) were adopted to verify the effects of butyrate on CSE1L­expressing CRC cells. The butyrate­producing gut bacteria Butyricicoccus pullicaecorum was administered to mice with 1,2­dimethylhydrazine­induced colon tumors before the measurement of CSE1L expression. The effects of B. pullicaecorum on CSE1L expression were then assessed by immunohistochemical staining for CSE1L and p53 in tissues from CRC­bearing mice. Non­cancerous colon cells with the R273H p53 mutation or CRC cells haboring p53 mutations were found to exhibit significantly higher CSE1L expression levels. CSE1L knockdown in HCT116 p53­/­ cells resulted in G1­and G2/M­phase cell cycle arrest. Furthermore, in HCT116 p53­/­ cells, CSE1L expression was already high at interphase, increased at prophase, peaked during metaphase before declining at cytokinesis but remained relatively high compared with that in HCT116 expressing wild­type p53. Significantly decreased expression levels of CSE1L were also observed in HCT116 p53­/­ cells that were treated with butyrate for 24 h. In addition, the migration of HCT116 p53­/­ cells was significantly decreased after CSE1L knockdown or butyrate treatment. Tumors with more intense nuclear p53 staining and weaker CSE1L staining were found in mice bearing DMH/DSS­induced CRC that were administered with B. pullicaecorum. Taken together, the results indicated that butyrate can impair CSE1L­induced tumorigenic potential. In conclusion, butyrate­producing microbes, such as B. pullicaecorum, may reverse the genetic distortion caused by p53 mutations in CRC by regulating CSE1L expression levels.

RESUMEN

Type 1 diabetes stem-cell-based therapy is one of the best therapeutic approaches for pancreatic damage treatment due to stem cell tissue regeneration. Epigallocatechin gallate (EGCG) is one of the active components found in green tea. Experimental results suggest that EGCG shows beneficial effects on cell protection. This study explores whether a better pancreatic regeneration therapeutic effect could be found in mesenchymal stem cells pretreated with EGCG compared to stem cells without EGCG pretreatment. A cell model confirmed that adipose-derived stem cells (ADSC) incubated with EGCG increase cell viability under high-glucose (HG) stress. This is due to survival marker p-Akt expression. In an animal model, type 1 diabetes induced the activation of several pathological signals, including islet size reduction, extracellular fibrotic collagen deposition, oxidative stress elevation, survival pathway suppression, apoptosis signaling induction, and Sirt1 antioxidant pathway downregulation. Ordinary ADSC transplantation slightly improved the above pathological signals. Further, EGCG-pretreated ADSC transplantation significantly improved the above pathological conditions. Taken together, EGCG-pretreated ADSCs show clinical potential in the treatment of patients with type 1 diabetes through the regeneration of damaged pancreatic tissues.

RESUMEN

Silver perch (Bidyanus bidyanus) has many nutrition and health benefits, being a rich source of macro and micronutrients, phospholipids, polyunsaturated fatty acids, and a variety of essential minerals while having a high protein content. In addition to direct consumption, it is often made into a soup as an important nutritional supplement for strengthening the body and delaying fatigue. By extracting the essence, its quality can be controlled, and it is convenient to supplement. This study aimed to evaluate the effect of supplementation with Santé premium silver perch essence (SPSPE) on improving exercise performance and anti-fatigue. Fifty male institute of cancer research (ICR) mice were divided into five groups (n = 10/group): (1) vehicle (vehicle control or water only), (2) isocaloric (0.93 g casein/kg/mice/day), (3) SPSPE-1X (0.99 g/kg/mice/day), (4) SPSPE-2X (1.98 g/kg/mice/day), and (5) SPSPE-5X (4.95 g/kg/mice/day). A sample or an equal volume of liquid was fed orally for four consecutive weeks. Grip strength and swimming exhaustion tests were used as exercise performance assessments. After 10 and 90 min of unloaded swimming, biochemical parameters of fatigue were evaluated. We found that supplementation with SPSPE for four consecutive weeks could significantly improve mice's grip strength, exercise endurance performance, and glycogen content (p < 0.05), and significantly reduced post-exercise fatigue biochemical parameters, such as lactate, blood ammonia (NH3), blood urea nitrogen (BUN) concentration, and muscle damage index creatine kinase (CK) activity (p < 0.05). In summary, supplementation with SPSPE for 4 weeks could effectively improve exercise performance, reduce sports fatigue, and accelerate fatigue recovery. In addition, it did not cause any physiological or histopathological damage.

RESUMEN

Recent studies have found that exosomes or extracellular vehicles (EVs) are associated with cancer metastasis, disease progression, diagnosis, and treatment, leading to a rapidly emerging area of exocrine vesicle research. Relying on the superior targeting function and bio-compatibility of exosomes, researchers have been able to deliver drugs to cancer stem cells deep within tumors in mouse models. Despite significant efforts made in this relatively new field of exosome research, progress has been held back by challenges such as inefficient separation methods, difficulties in characterization/tracking, and a lack of specific biomarkers. Therefore, current researches are devoted to combining nanomaterials with exosomes to improve these shortcomings. Adding inorganic/organic nanoparticles such as artificial liposomes and iron oxide can bring more drug options and various fluorescent or magnetic diagnostic possibilities to the exosome system. Moreover, the applications of exosomes need to be further evaluated under actual physiological conditions. This review article highlights the potential of exosome-biomimetic nanoparticles for their use as drug carriers to improve the efficacy of anticancer therapy.

RESUMEN

BACKGROUND: Accumulating evidence shows that women experience serious psychological distress after terminating their pregnancy for fetal anomaly (TOPFA). Although the number of studies on psychosocial interventions (PSIs) for TOPFA women has increased, access to evidence-based support for medical staff who provide care to TOPFA women remains limited. A systematic review was conducted to provide an overview of available PSIs. METHODS: Nine major electronic databases in available in English and Chinese languages were searched to identify articles published from the databases' inception to November 2021. Our participants were TOPFA women; interventions were PSIs; the comparison was no limits; outcomes were psychological distress including depression, anxiety, and post-traumatic stress (PTSD); and study designs were experimental studies including randomized controlled trials (RCTs) and quasi-experimental studies. The Joanna Briggs Institute Critical Appraisal Checklist for RCTs and quasi-experimental studies was used to assess the quality of evidence. Subsequently, synthesis without meta-analysis of the findings was completed. RESULTS: A total of 1,730 studies were identified from the initial database, 37 of which were included in this research. The interventions tested included cognitive therapy, mindfulness, sandplay therapy, psychological counseling, family support, peer support, empathy nursing, bereavement care, solution-focused psychological nursing, and staged psychological nursing. Four of these studies were RCTs. Most interventions were implemented in hospitals in China by nurses. However, few studies reported details on implementation procedures, and the studies presented substantial heterogeneity. Most of the included studies were judged to be of high risk of bias. DISCUSSION: Although this review was limited by search strategies and most of the included studies were of low quality, it still provided some tentative support for PSIs for the treatment of TOPFA women. Further research is warranted to investigate the effects of specific components on TOPFA women by using randomized controlled designs and reporting intervention manuals based on psychotherapeutic theory.
