- ArticleShuman S, Cason P, Manze M.Contraception. 2023 Nov;127:110135.OBJECTIVES: PATH, "Parenting/Pregnancy Attitudes, Timing, and How Important," is a method for providers to engage in a person-centered discussion about reproductive desires. This study sought to assess patient understanding of and receptivity to PATH questions.
STUDY DESIGN: Cognitive interviews were conducted with young adult (aged 18-29 years) patients at a federally qualified health center in New York (n = 10).
RESULTS: Participants demonstrated clear comprehension and comfort with the PATH questions.
IMPLICATIONS: These data provide needed person-driven support for the Centers for Disease Control and Prevention and the Society of Family Planning's recommendation to implement PATH questions as a patient-centered method for discussing an individual's reproductive desires. - ArticleSuchko S, Smida T, Crowe RP, Menegazzi JJ, Scheidler JF, Shukis M, Martin PS, Bardes JM, Salcido DD.Resuscitation. 2024 Mar;196:110135.INTRODUCTION: Following initial resuscitation from out-of-hospital cardiac arrest, rearrest frequently occurs and has been associated with adverse outcomes. We aimed to identify clinical, treatment, and demographic characteristics associated with prehospital rearrest at the encounter and agency levels.
METHODS: Adult non-traumatic cardiac arrest patients who achieved ROSC following EMS resuscitation in the 2018-2021 ESO annual datasets were included in this study. Patients were excluded if they had a documented DNR/POLST or achieved ROSC after bystander CPR only. Rearrest was defined as post-ROSC CPR initiation, administration of ≥ 1 milligram of adrenaline, defibrillation, or a documented non-perfusing rhythm on arrival at the receiving hospital. Multivariable logistic regression modeling was used to evaluate the association between rearrest and case characteristics. Linear regression modeling was used to evaluate the association between agency-level factors (ROSC rate, scene time, and scene termination rate), and rearrest rate.
RESULTS: Among the 53,027 cases included, 16,116 (30.4%) experienced rearrest. Factors including longer response intervals, longer 'low-flow' intervals, unwitnessed OHCA, and a lack of bystander CPR were associated with rearrest. Among agencies that treated ≥ 30 patients with outcome data, the agency-level rate of rearrest was inversely associated with agency-level rate of survival to discharge to home (R2 = -0.393, p < 0.001).
CONCLUSIONS: This multiagency retrospective study found that factors associated with increased ischaemic burden following OHCA were associated with rearrest. Agency-level rearrest frequency was inversely associated with agency-level survival to home. Interventions that decrease the burden of ischemia sustained by OHCA patients may decrease the rate of rearrest and increase survival. - ArticleKhounsarian F, Abu-Omar A, Emara A, Marinescu D, Yong-Hing CJ, Ali IT, Khosa F.Clin Imaging. 2024 May;109:110135.Despite the demonstrated benefits of gender diversity in medicine, women in Radiology in North America are still underrepresented. We reviewed the literature to highlight the current status of women in Radiology in North America, identify the underlying causes of the gender gap, and provide potential strategies to close this gap. We conducted a narrative literature review using the terms ("Gender Disparity" OR "Gender Inequality") AND ("Radiology Department" OR "Radiology Residency"), searching data from April 2000 to April 2022 in Ovid Medline, Embase, PubMed, and Scopus. Our results indicate that Radiology in North America lacks gender diversity in its subspecialties, academic leadership, and research productivity, which the COVID-19 pandemic has further exacerbated. Challenges stemming from a dearth of women role models, limited preclinical contact, and a high rate of burnout contribute to the current gender inequality. Several complementary and supplementary steps can enhance gender diversity in Radiology. These include increasing education and exposure to Radiology at earlier stages and optimizing mentorship opportunities to attract a more diverse pool of talent to the discipline. In addition, supporting resident parents and enhancing the residency program's culture can decrease the rate of burnout and encourage women to pursue careers and leadership positions in Radiology.
- ArticleMorsi DS, Barnawi IO, Ibrahim HM, El-Morsy AM, El Hassab MA, Abd El Latif HM.Int Immunopharmacol. 2023 Jun;119:110135.Sildenafil is a potent phosphodiesterase-5 (PDE5) inhibitor that effectively inhibits cGMP and increases the strength of nitric oxide. PDE5 was overexpressed in several carcinomas, including breast cancer, which inhibited tumor growth and cell division. The current research aims to investigate the in vivo sildenafil's immunomodulatory and antineoplastic potentials against Ehrlich Ascites Carcinoma. This study looked at the effects of sildenafil mono-treatment and co-treatment with cisplatin; tumor cell count, viability and the inhibition rate were determined. Apoptosis, cell cycle distribution, alterations in tumor cells and splenocytes proliferation, changes in splenocytes immunophenotyping using flowcytometry, plasma levels of malondialdehyde (MDA), reduced glutathione (GSH), interferone (IFN)-γ, granzyme B, alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea, creatinine and hematological alterations were detected. Additionally, docking study was conducted to get further insights on how Sildenafil exerts its activity. Sildenafil mono-treatment and co-treatment with cisplatin markedly reduced tumor cell count, viability, growth rate and proliferative capability accompanied by apoptosis enhancement and G0/G1 and sub G1 cells cycle arrest. Fortunately, sildenafil evoked efficient cellular immune response by increasing plasma levels of granzyme B and IFN-γ, proportion of splenic T cytotoxic (CD3+CD8+) and T helper (CD3+CD4+), accompanied by decrease in the proportion of splenic regulatory T cells. . Moreover, in silico data suggest LcK and MAPKs as the potential targets of sildenafil. Furthermore, sildenafil rebalanced the oxidant-antioxidant status by decreasing MDA and increasing GSH plasma levels. Sildenafil successfully retrieved various hematological values besides renal and hepatic functions in EAC-bearing animals. In conclusion, our results suggest that sildenafil could be potential safe anti-tumor agent with immuno-modulatory properties against Ehrlich ascites carcinoma.

- ArticleShih HS, Gordon J, Kulig K.J Biomech. 2021 01 04;114:110135.The active control of the trunk plays an important role in frontal plane gait stability. We characterized trunk control in response to different step widths using a novel feedback system and examined the different effects of wide and narrow step widths as they each present unique task demands. Twenty healthy young adults walked on a treadmill at 1.25 m/s at five prescribed step widths: 0.33, 1.67, 1, 1.33, 1.67 times preferred step width. Motion capture was used to record trunk kinematics, and surface electromyography was used to record longissimus muscle activation bilaterally. Vector coding was used to analyze coordination between pelvis and thorax segments of the trunk. Results showed that while center of mass only varied across step width in the mediolateral direction, trunk kinematics in all three planes were affected by changes in step width. Angular excursions of the trunk segments increased only with wider widths in the transverse plane. Thorax-pelvis kinematic coordination was affected more by wider widths in transverse plane and by narrower widths in the frontal plane. Peak longissimus activation and bilateral co-activation increased as step widths became narrower. As a control task, walking with varied step widths is not simply a continuum of adjustments from narrow to wide. Rather, narrowing step width and widening step width from the preferred width represent distinct control challenges that are managed in different ways. This study provides foundation for future investigations on the trunk during gait in different populations.

The incubation protocol followed the IVRI method, adding polyethylene glycol (PEG) as a polyphenol-blocking agent. The L3 were incubated in ruminal liquor (RL), ruminal liquor with PEG (RL+PEG), ruminal liquor with G. floribundum extract (RLE), and ruminal liquor with G. floribundum extract and PEG (RLE+PEG). Incubation condition controls included phosphate buffered saline (PBS), PBS with PEG (PBS+PEG), incubation medium (without ruminal liquor) (IM), and incubation medium with PEG (IM+PEG). The L3 were recovered after incubation times of 0, 1, 3, 6, 9, and 24 h (39 °C). The respective L3 exsheathment kinetics were estimated for the different treatments (RL, RL+PEG, RLE, and RLE+PEG) using Log-Logistic models. The parameters of the different models were compared to determine the impact of the extract, with or without PEG, on the L3 exsheathment kinetics. The exsheathment in PBS and PBS+PEG remained < 2.71% at each incubation time. The exsheathment in IM and IM+PEG reached 13.58% and 17.18% at 24 h, respectively. The exsheathment percentages for RLE were lower than those for RL at 3, 6 and 9 h of incubation. The inflection point, indicating the time required to reach 50% of the maximal exsheathment (T50), was the only parameter that differed between the ruminal liquor models. The T50 in RLE (7.106 h) was higher than the values obtained for RL (5.385 h) and RL+PEG (4.923 h) (99.99% probability of being different). Such delay resulted in a reduction of exsheathment in RLE of 62% at 3 h, 38% at 6 h, and 12% at 9 h, relative to RL values. When PEG was added with the extract (RLE+PEG), the T50 (5.045 h) was similar to that of RL and RL+PEG. The IVRI method was adapted as an in vitro rumen exsheathment test (IVRET). The IVRET showed that H. contortus L3 exposed to G. floribundum extract delayed their exsheathment kinetics at different time points. The exsheathment delay was attributed to the polyphenol content of the extract.
- ArticleDai Y, Zhuang J, Chen X.Environ Res. 2020 12;191:110135.This study examines the effects of soil organic matter (SOM) and water content on the transport of five selected pharmaceutical and personal care products (PPCPs, ibuprofen, carbamazepine, bisphenol A, tetracycline, and ciprofloxacin) in four natural soils with different SOM contents. Batch isotherm experiment results showed that SOM effect was very significant for positively charged tetracycline and ciprofloxacin (>99% adsorption, no desorption), relatively significant for non-dissociated carbamazepine and bisphenol A (17-57% adsorption, 6-71% desorption) and insignificant for negatively charged ibuprofen (4-8% adsorption, 60-87% desorption) in the soils. Transport results showed that neither tetracycline nor ciprofloxacin moved through the saturated and unsaturated soil columns, demonstrating their very limited mobility in soils as a result of significant electrostatic attraction independent of SOM and water conditions. Overall, higher SOM content and lower water content were favorable to the retention of ibuprofen, carbamazepine and bisphenol A in the soils. Breakthrough of ibuprofen, carbamazepine and bisphenol A was 100% (both saturated and unsaturated), 94% (saturated)-97% (unsaturated) and 85% (saturated)-90% (unsaturated) in SOM-removed soils; however only 78% (saturated)-57% (unsaturated), 93% (saturated)-67% (unsaturated), 11% (saturated)-0% (unsaturated) in the SOM-high soils. The effect of water content was not significant in the SOM-removed soils. The SOM could increase the kinetic (type 2) adsorption of PPCPs at the solid-water interface (SWI), and the air phase could increase the instantaneous (type 1) adsorption of PPCPs at the air-water interface (AWI). This result suggests that lowering water content could greatly enhance the adsorption of PPCPs that had high affinities to soils and vice versa. This study provides an important implication that AWI and SWI might have a nonlinear relationship in promoting the adsorption and reducing the mobility of PPCPs under unsaturated flow conditions.

Contradictory data have been published on Hp-I and multiple sclerosis (MS) association, with studies mainly using serology for Hp-I detection that cannot distinguish between active and past infections. We herein hypothesize that humoral and cellular immune responses induced by active Hp-I, beyond damaging locally the gastric mucosa, they may shape the character of systemic autoimmune responses, contributing to MS pathogenesis. To investigate our hypothesis, active Hp-I has been diagnosed in two small MS Greek cohorts by using primarily gastric mucosa histology. A higher prevalence of active Hp-I was documented in MS patients vs. controls (86.4 vs. 50%, P = 0.002)accompanied by exclusive existence of duodenal ulcer and autoimmune diseases with endoscopic and histological findings of chronic active gastritis for the MS group. Our preliminary data suggested that active Hp-Iunlike other studies, may not protect, but contribute to MS and we proposed possibleHp-relating mechanisms involved in MS pathophysiology, that merit further evaluation.

Berg) was added in different concentrations: 5% (I5 sample) and 10% (I10 sample), compared to a control sample, with no pulp addition. In these fermented milks, Bifidobacterium BB-12 was added and the samples were submitted to a progressive gastrointestinal simulation in vitro. The cells count was performed, including the survival rates for all the progressive steps of the simulated digestion. Total phenolic content (TPC) and antioxidant activity analysis by FRAP (Ferric Reducing Antioxidant Power) and DPPH (2,2-diphenyl-1-picrylhydrazyl) were performed in all the gastrointestinal steps. Before and during the entire gastrointestinal tract, the Bifidobacterium BB-12 count was 8-9 log CFU g-1, above the recommended for a probiotic product, with a highlight in intestinal colon steps. The I10 sample showed the highest viable cell count, the highest total phenolic content and antioxidant activity throughout the entire gastric steps (p < 0.05). The fermented milk proved to be an effective matrix for the probiotic stability and incorporation of guabiroba components. Bioactive compounds present in the guabiroba pulp may have occasioned a prebiotic and protective effect on Bifidobacterium BB-12 after gastric conditions. The possible bioconversion of these compounds in more active forms can contribute to the absorption in epithelial cells, enhancing fermented milks with guabiroba pulp as important sources of dietary accessible bioactive compounds.
- ArticleWest R, Mobilia M.J Theor Biol. 2020 04 21;491:110135.Rock-paper-scissors games metaphorically model cyclic dominance in ecology and microbiology. In a static environment, these models are characterized by fixation probabilities obeying two different "laws" in large and small well-mixed populations. Here, we investigate the evolution of these three-species models subject to a randomly switching carrying capacity modeling the endless change between states of resources scarcity and abundance. Focusing mainly on the zero-sum rock-paper-scissors game, equivalent to the cyclic Lotka-Volterra model, we study how the coupling of demographic and environmental noise influences the fixation properties. More specifically, we investigate which species is the most likely to prevail in a population of fluctuating size and how the outcome depends on the environmental variability. We show that demographic noise coupled with environmental randomness "levels the field" of cyclic competition by balancing the effect of selection. In particular, we show that fast switching effectively reduces the selection intensity proportionally to the variance of the carrying capacity. We determine the conditions under which new fixation scenarios arise, where the most likely species to prevail changes with the rate of switching and the variance of the carrying capacity. Random switching has a limited effect on the mean fixation time that scales linearly with the average population size. Hence, environmental randomness makes the cyclic competition more egalitarian, but does not prolong the species coexistence. We also show how the fixation probabilities of close-to-zero-sum rock-paper-scissors games can be obtained from those of the zero-sum model by rescaling the selection intensity.
- ArticlePieniak M, Tutar C, Jedryczka W, Benkhatar H, Debroise Blanchard-Dignac V, Haehner A, Hummel T.J Neurosci Methods. 2024 Jun;406:110135.BACKGROUND: Olfactory perceptions elicited by odors originating from within the body (retronasal olfaction) play a crucial role in well-being and are often disrupted in various medical conditions. However, the assessment of retronasal olfaction in research and the clinical practice is impeded by the lack of commercially available tests and limited standardization of existing testing materials.
NEW METHOD: The novel ThreeT retronasal odor identification test employs 20 flavored tablets that deliver a standardized amount of odorous stimuli. The items represent common food- and non-food-related odors.
RESULTS: The ThreeT test effectively distinguishes patients with olfactory dysfunction from healthy controls, achieving a specificity of 86% and sensitivity of 73%. Its scores remain stable for up to 3 months (r=.79).
COMPARISON WITH EXISTING METHOD: ThreeT test exhibits a strong correlation with "Tasteless powders" measure of retronasal olfaction (r=.78) and classifies people into healthy and patient groups with similar accuracy. Test-retest stability of ThreeT is slightly higher than the stability of "Tasteless powders" (r=.79 vs r=.74).
CONCLUSIONS: ThreeT is suitable for integration into scientific research and clinical practice to monitor retronasal odor identification abilities. - ArticleKibambe MG, Momba MNB, Daso AP, Van Zijl MC, Coetzee MAA.J Environ Manage. 2020 Apr 15;260:110135.The occurrence of endocrine-disrupting compounds (EDCs) consisting of natural and synthetic estrogens, namely estrone (E1), 17β-estradiol (E2), estriol (E3) and 17α-ethinylestradiol (EE2) was quantified in wastewater samples. The aim of this study was to assess the removal efficiency for the selected estrogens (E1, E2, E3 and EE2) and reduction of estrogenic activity in wastewater samples from wastewater treatment plants (WWTPs) using different processes. Solid-phase extraction (SPE) followed by liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods were used to quantify the selected estrogens in wastewater samples. Estrogenic activity was assessed using the T47D-KBluc gene reporter assay. Results revealed a decrease in estrogen concentrations observed in the effluents of all the WWTPs, except for E2 at Daspoort where no removal was noted. In general, the highest removal for total estrogens was observed at Phola (84%) combining three processes (AP, BF and wetland). The AS at Daspoort had a highest removal of 75% for E3; while at Zeekoegat the highest removal reached 61% for EE2. The PST at Daspoort had no removal recorded for all the compounds, except for the EE2 (33%). The AP and BF systems at Phola contributed to a higher removal of selected compounds. Downstream of the wetland at Phola no removal was recorded for E3; while the highest removal reached 61% for E1. The best performance in terms of the overall influent-to-effluent removal efficiency was observed at Phola WWTP, where E1 removal of 85% was recorded. The highest estrogenic activity in the effluent was reported at Phola, with an average estradiol equivalent (EEQ) value of 6.3 ± 6.7 ng/L. However, no anti-estrogenic activity was detected in any of the samples. The daily mass load discharged from the effluent of the three WWTPs was higher for E1 recorded at Zeekoegat (8002.3 ± 6416.3 mg/d), followed by Daspoort (3509.8 ± 849.0 mg/d) and finally Phola (176.1 ± 34.9).
- ArticleLi J, Liang Y, He Z, Zhong M, Hu Z.Enzyme Microb Technol. 2023 Jan;162:110135.Laminarinases from the glycoside hydrolase 16 (GH16) family are hydrolases that break β-1,3-glycosidic bonds in laminarin, which is the major storage polysaccharide present in brown algae or microalgae. We explored a laminarinase from the marine Flavobacteriaceae species Tamlana sp. PT2-4 at the structural and functional levels. Based on a homology model of Lam1092-substrate interactions, the large active groove crossing Lam1092 was deemed a reasonable pathway for the bent substrates for hydrolysis. Eight residues (Gly361, Asn364, Arg400, His466, Asp449, Glu452, Ser477 and Thr538) were selected for mutagenesis based on the interactions of Lam1092 in complex with Lam4/Lam6. Ultimately, we generated eight mutants of Lam1092, and the antioxidant activities of the hydrolysates of two mutants (G361A and H466A) showed significant improvement. These results show that the antioxidant activity of laminarin can be improved by laminarinase mutation, which will be beneficial for developing efficient approaches to engineer the substrate specificity of laminarinases and improve the application of bioactive laminarioligosaccharides.
- ArticleMabeta P.Biomed Pharmacother. 2020 Jul;127:110135.Melanoma is the most aggressive form of skin cancer. Malignant melanoma in particular has a poor prognosis and although treatment has improved, drug resistance continues to be a challenge. Angiogenesis, the formation of blood vessels from existing microvessels, precedes the progression of melanoma from a radial growth phase to a malignant phenotype. In addition, melanoma cells can form networks of vessel-like fluid conducting channels through vasculogenic mimicry (VM). Both angiogenesis and VM have been postulated to contribute to the development of resistance to treatment and to enable metastasis. Also, the metastatic spread of melanoma is highly dependent on lymphangiogenesis, the formation of lymphatic vessels from pre-existing vessels. Interestingly, the design and clinical testing of drugs that target VM and lymphangiogenesis lag behind that of angiogenesis inhibitors. Despite this, antiangiogenic drugs have not significantly improved the overall survival of melanoma patients, thus necessitating the targeting of alternative mechanisms. In this article, I review the roles of the three paradigms of tissue perfusion, namely, angiogenesis, VM and lymphangiogenesis, in promoting melanoma progression and metastasis. This article also explores the latest development and potential opportunities in the therapeutic targeting of these processes.
- ArticleQuinn M, Brettell T, Joshi M, Bonetti J, Quarino L.Forensic Sci Int. 2020 Feb;307:110135.Identifying drug analogs can be a vexing problem for forensic scientists particularly in today's evolving drug market. This study proposes a method that utilizes microcrystalline tests, Raman microspectroscopy, and chemometrics to help solve this problem. In the present case, the method described was used to clearly differentiate and identify phencyclidine (PCP) and four of its analogs, namely tenocyclidine (TCP), rolicyclidine (PCPy), 3-methoxy phencyclidine (3-MeO PCP), and 4-methoxy phencyclidine (4-MeO PCP). Microcrystals were grown from each drug with gold chloride and examined using polarized light microscopy. Morphological and optical properties such as shape, habit, time of growth, color, retardation colors, type/angle of extinction, and sign of elongation were observed and documented to characterize each microcrystal. Analysis with a Raman microscope was able to provide structural information on the microcrystals. Objective analysis of the microcrystal spectra was done by employing chemometrics. A training set of Raman shifts was compiled and transformed with principal component analysis (PCA) followed by linear discriminant analysis (LDA). The training set was validated by leave-one-out cross validation (LOOCV) and subsequently ran against a separately-compiled test set. Mahalanobis distances between test samples and the clusters of training samples in LDA space were calculated to empirically demonstrate the applicability of this drug analysis technique. From the results of this study, a drug analysis protocol was developed for analysts to use for the identification of PCP, TCP, PCPy, 3-MeO PCP, and 4-MeO PCP and to serve as a model for drug analogs in general.
- ArticleLaunay CP, de Decker L, Kabeshova A, Annweiler C, Beauchet O.PLoS One. 2014;9(10):e110135.BACKGROUND: The aims of this study were 1) to confirm that combinations of brief geriatric assessment (BGA) items were significant risk factors for prolonged LHS among geriatric patients hospitalized in acute care medical units after their admission to the emergency department (ED); and 2) to determine whether these combinations of BGA items could be used as a prognostic tool of prolonged LHS.
METHODS: Based on a prospective observational cohort design, 1254 inpatients (mean age ± standard deviation, 84.9±5.9 years; 59.3% female) recruited upon their admission to ED and discharged in acute care medical units of Angers University Hospital, France, were selected in this study. At baseline assessment, a BGA was performed and included the following 6 items: age ≥85years, male gender, polypharmacy (i.e., ≥5 drugs per day), use of home-help services, history of falls in previous 6 months and temporal disorientation (i.e., inability to give the month and/or year). The LHS in acute care medical units was prospectively calculated in number of days using the hospital registry.
RESULTS: Area under receiver operating characteristic (ROC) curves of prolonged LHS of different combinations of BGA items ranged from 0.50 to 0.57. Cox regression models revealed that combinations defining a high risk of prolonged LHS, identified from ROC curves, were significant risk factors for prolonged LHS (hazard ratio >1.16 with P>0.010). Kaplan-Meier distributions of discharge showed that inpatients classified in high-risk group of prolonged LHS were discharged later than those in low-risk group (P<0.003). Prognostic value for prolonged LHS of all combinations was poor with sensitivity under 77%, a high variation of specificity (from 26.6 to 97.4) and a low likelihood ratio of positive test under 5.6.
CONCLUSION: Combinations of 6-item BGA tool were significant risk factors for prolonged LHS but their prognostic value was poor in the studied sample of older inpatients. - Articlevon Sengbusch S, Schneidewind J, Bokelmann J, Scheffler N, Bertram B, Frielitz FS, Hiort O, Lange K.Diabetes Res Clin Pract. 2022 Nov;193:110135.AIMS: To explore the impact of primarily telemedical care for children and adolescents with type 1 diabetes by monthly video consultations on metabolic control and parents' treatment satisfaction and disease-specific burden during the COVID-19 pandemic.
METHODS: In this 12-month multicenter observational follow-up VIDIKI 2.0 study, 100 participants (3-18 years) received monthly video consultations, which partially replaced quarterly outpatient clinic appointments during the pandemic. The children's metabolic parameters as well as the parents' treatment satisfaction and diabetes specific burden were assessed at study entry and 12 months later.
RESULTS: During the study, 912 video consultations took place (mean 0.84 ± 0.23 / patient/month). The children's HbA1c remained stable, while mean sensor glucose level and glucose management indicator decreased. Simultaneously, parents' treatment satisfaction significantly increased, and their diabetes-specific burden and distress decreased.
CONCLUSIONS: Primarily telemedical care of children and adolescents with type 1 diabetes during the COVID-19 pandemic via monthly video consultations resulted in a significant improvement in parents' treatment satisfaction and their diabetes-specific burden and distress. It was associated with a slight improvement in mean sensor glucose and glucose management indicator, while HbA1c remained stable. Thus, video consultations offer great potential to enhance standard care for children and adolescents with diabetes. - ArticleYu R, Zhong J, Zhou Q, Ren W, Liu Z, Bian Y.Chem Biol Interact. 2022 Oct 01;366:110135.Kaempferol is a major flavonoid found in natural plant extracts; it shows great potential in anti-inflammatory and anti-cancer medicine. However, the underlying mechanism of the protective action of kaempferol on the gut-vascular barrier (GVB) and the active sites preventing intestinal micro-angiogenesis has not been reported. The purpose of our study is to investigate the protective effect of kaempferol on the barrier damage induced by lipopolysaccharide (LPS) and tumor necrosis factor-alpha (TNF-α), and its mechanism of protective action on intestinal micro-angiogenesis. Our data showed that the combination of LPS and TNF-α activates the inflammatory response of the rat intestinal microvascular endothelial cells (RIMVECs), leading to overexpression of vascular endothelial growth factors (VEGFs). Also, the permeability of GVB and transepithelial electrical resistance (TEER) constructed by Transwell and the tubular structure of RIMVEC were significantly affected. Kaempferol (25, 50, and 100 μM) decreased the inflammatory factor secretion and GVB permeability, down-regulated the expression of VEGFs, p-Akt, and hypoxia-inducible factor-1alpha (HIF-1α). It also alleviated the abnormal expression of tight junction proteins (TJs). Moreover, kaempferol may prevents intestinal angiogenesis in the presence of Akt inhibitor (MK-2206 2HCl) by regulating tube formation and downstream signaling of the VEGF/Akt pathways. In addition, the wound healing test showed that kaempferol had a similar effect in the presence of p38 inhibitor (SB203580), which intuitively restrained the migration of RIMVECs and reduced the p38 MAPK signaling. Our results demonstrated that kaempferol exhibits significant anti-inflammatory effects in LPS and TNF-α induced inflammatory environments. Kaempferol prevents intestinal angiogenesis by impeding the tube formation and migration of RIMVECs. It also suppresses the expression of angiogenesis-related signals, thereby protecting the GVB.
