[PMID: 36832811 PMCID: PMC9956570 DOI: 10.3390/foods12040733] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2022] [Revised: 01/14/2023] [Accepted: 01/19/2023] [Indexed: 02/10/2023] Open
Abstract
The present study aimed to investigate the effect of different microwave pre-drying times under hot-air-drying processes on the quality properties and sensory evaluation of Sipunculus nudus (S. nudus). The colour, proximate analysis, amino acid content, fat oxidation, and volatile components of dried S. nudus were determined. Microwave pre-drying could significantly (p < 0.05) increase the drying rate and shorten the drying time. The results of colour, proximate analysis, and amino acid content indicated that microwave pre-drying could improve the quality of the product, resulting in dried S. nudus with less of a loss in nutrients. The samples that underwent microwave pre-drying had a high degree of fatty acid oxidation and low monounsaturated fatty acid content, which facilitated the formation of volatile components. Additionally, the MAD-2 and MAD-3 groups had high relative contents of aldehydes and hydrocarbons, and the FD group had the highest relative content of esters found in the samples. The relative content of ketones and alcohols did not differ significantly between the different drying groups. The finding of this study has important potential for enhancing the quality and aroma of dry S. nudus products with microwave pre-drying during the drying process.

Abstract
OBJECTIVES Emerging evidences have explored the association between famine exposure during early life and cancer risk in adulthood, but the results remain controversial and inconsistent. This study aimed to provide a comprehensive evidence on the relation of famine exposure to later cancer risk. DESIGN Systematic review and meta-analysis. METHODS Relevant reports published up to March, 2022 were identified by searching PubMed, Embase, Web of sciences and Medline databases. Pooled relative ratios (RRs) with 95% confidence intervals (CIs) were used to evaluate the effect famine exposure on cancer risk. RESULTS Totally, 18 published articles with 6,061,147 subjects were included in this study. Compared with unexposed group, early life famine exposure dramatically increased the risk of cancer in adulthood (RR=1.13, 95% CI: 1.04-1.22). The pooled RRs were different in terms of sex, exposure severity, exposure period, famine type, study design type and cancer location. A remarkably elevated risk for cancer was discerned in women exposed to famine (RR=1.09, 95% CI: 1.00-1.18), severe exposure (RR=1.12, 95% CI: 1.02-1.22) and adolescence exposure (RR=1.76, 95% CI: 1.02-2.50), Chinese famine exposure (RR=1.55, 95% CI: 1.29-1.82) and cohort studies (RR=1.28, 95% CI: 1.13-1.42). Moreover, a significant association of early-life famine exposure with increased risk of breast (RR=1.16, 95% CI: 1.05-1.27) and stomach cancers (RR=1.89, 95% CI: 1.24-2.54) was observed. CONCLUSION This meta-analysis suggests that exposure to famine during early life may increase the risk of cancer in adulthood. The above-mentioned association is pronounced in women exposed to famine, severe exposure, adolescence exposure, Chinese famine, cohort studies, breast and stomach cancers. It is essential for decision-makers to take targeted measures for improving population awareness regarding the long-term effect of early life nutritional status.

Abstract
Objectives: To analyze the effects of Helicobacter pylori (H. pylori) infection and eradication therapy on small intestinal bacterial overgrowth (SIBO). Methods: From September to December 2021, patients with abdominal symptoms who received 13C urea breath test at the Department of Gastroenterology in Peking University First Hospital were enrolled.13C urea breath test was used to detect H. pylori infection and patients were divided into H. pylori positive and negative groups accordingly. Lactulose hydrogen methane breath test was performed to determine SIBO. H. pylori positive patients were treated with quadruple therapy including amoxicillin, metronidazole, rabeprazole and bismuth potassium citrate. 13C urea breath test and lactulose hydrogen methane breath test were reexamined 6 weeks after the treatment. Results: A total of 102 patients (49 males and 53 females) were enrolled, with a mean age of (42.1±9.9) years. Among them, 49 patients were H. pylori negative and 53 were H. pylori positive. Moreover, 47 patients were SIBO positive and 55 were SIBO negative. There was no significant difference in age, sex, body mass index, abdominal symptoms and the diagnosis of chronic atrophic gastritis between H. pylori positive and negative patients at the enrollment (all P>0.05). The detection rate of SIBO in H. pylori infected patients was higher than that in uninfected patients, and the difference was statistically significant (60.4% vs 30.6%, P=0.003). Patients with SIBO had significantly more frequent abdominal distension (36.2% vs 10.9%, P=0.002) and constipation (27.7% vs 1.8%, P<0.001) than patients without SIBO. The rate of SIBO after H. pylori eradication treatment was significantly lower than that before treatment (20.8% vs 60.4%, P<0.001). The remission rate of SIBO after eradication therapy was 66.7% (20/30). Besides, patients had obvious improvement of constipation (6.0% vs 18.9%, P=0.008), and the incidence of other abdominal symptoms decreased to various degrees including diarrhea, abdominal pain, abdominal distention and poor appetite. Conclusion: H. pylori infection increases the risk of SIBO, and the quadruple regimen containing amoxicillin and metronidazole has a therapeutic effect for patients with H.pylori infection and concomitant SIBO.

Abstract
OBJECTIVE This study aimed to analyze the medium-term outcomes of ultralight type I mesh for postmenopausal women with recurrent severe posterior vaginal prolapse (PVP). METHODS All participants underwent transvaginal ultralight type I mesh repair between April 2016 and April 2021 and were followed until May 2022. Pelvic Organ Prolapse Quantification System (POP-Q) staging, mesh-related complications, Patient Global Impression of Improvement (PGI-I) scale and quality of life questionnaire responses were evaluated. The primary outcome was composite surgical success rate at the last follow-up, composite success being defined as no vaginal bulge symptoms, no POP-Q point at or beyond the hymen and no re-treatment for POP. Secondary outcomes included anatomic outcomes (POP-Q score), symptomatic relief and complications. RESULTS The median follow-up was 37.3 months. At the last follow-up, the composite success rate was 75%, and POP-Q scores for the vault and posterior wall and quality of life questionnaire scores were significantly improved (p < 0.01). The subjective satisfaction (PGI-I ≤ 2) rate was 83.3%. There were no mesh-related complications. CONCLUSIONS Ultralight mesh can achieve good clinical outcomes and substantially improve the quality of life of patients with severe recurrent PVP in the medium term, and may thus be a viable alternative for treating this condition.

Abstract
Cyprinid herpesvirus 2 (CyHV-2) has caused great losses to the gibel carp (Carassius auratus gibelio) industry. Previous studies showed that certain DNA viruses can encode circular RNAs (circRNAs) to regulate virus infection, which provides new clues for the treatment of viral disease. Whether CyHV-2 can encode circRNAs is still unknown. Here, 10 CyHV-2-derived circRNAs were identified, and the function of circ-udg, a circRNA derived from the CyHV-2 uracil DNA glycosylase (udg) gene, was studied. Although the expression level of circ-udg was lower than that of the parental gene, udg, its expression level was elevated in tandem with the proliferation of CyHV-2 and udg. In vitro experiments confirmed that circ-udg could promote the proliferation of CyHV-2. Moreover, circ-udg could encode a truncated UDG protein consisting of 147-amino-acid residues (termed circ-udg-P147). Both UDG and circ-udg-P147 were found to promote CyHV-2 proliferation, but the promoting effect of circ-udg on CyHV-2 proliferation was attenuated after circ-udg lost the ability to encode circ-udg-P147. Also, circ-udg-P147 could not change the transcription level of the udg gene. Interestingly, the UDG protein level was increased by circ-udg-P147. These results deepen the understanding of the genetic information carried by the genome of CyHV-2 and provide a new target for the treatment of gibel carp bleeding disease caused by CyHV-2. IMPORTANCE The outbreak of C. auratus gibelio gill hemorrhagic disease caused by CyHV-2 brought great losses to the gibel carp industry. Therefore, exploring the interaction between CyHV-2 and host and the molecular mechanism of viral infection is of great significance in preventing and treating the gibel carp gill hemorrhagic disease. Although some progress has been made in the study of CyHV-2, the mechanism of interaction between CyHV-2 and crucian carp is still unclear. In this study, we found that CyHV-2 can encode circRNA to regulate virus replication. Our study provides novel information on CyHV-2 functional genomics, a reference for research into the circRNA of other viruses, and theoretical guidance for preventing and treating gibel carp bleeding disease.

Abstract
As a type of highly plastic innate immune cells, macrophages may be differentiated into M1 and M2 macrophages upon different stimuli, and M2 macrophages are involved in immune regulation, tissue remodeling and regeneration, and wound healing. Previous epidemiological studies have shown a significant negative correlation between the prevalence of helminth infections and the incidence of inflammatory diseases, such as allergy and autoimmune diseases. As a common type of intestinal helminths, hookworm infection may trigger high levels of type II host immune responses, with alternative activation of macrophages, which are effective to inhibit the development and progression of inflammatory diseases. This review summarizes the advances in alternative activation of macrophages in hookworm therapy for inflammatory diseases.

Abstract
Experimental measurements show that the angular dependence of the anisotropic magnetoresistance (AMR) in L1_{0} ordered FePt epitaxial films on the current orientation and magnetization direction is a superposition of the corresponding dependences of twofold and fourfold symmetries. The twofold AMR exhibits a strong dependence on the current orientation, whereas the fourfold term only depends on the magnetization direction in the crystal and is independent of the current orientation. First-principles calculations reveal that the fourfold AMR arises from the relaxation time anisotropy due to the variation of the density of states near the Fermi energy under rotation of the magnetization. This relaxation time anisotropy is a universal property in ferromagnetic metals and determines other anisotropic physical properties that are observable in experiment.

Abstract
BackgroundViral hepatitis is a widespread and serious infectious disease, and most patients with liver cirrhosis and hepatocellular carcinoma are prone to viral infections. T cell immunoglobulin-and mucin-domain-containing molecule-3 (Tim-3) is an immune checkpoint molecule that negatively regulates T cell responses, playing an extremely important role in controlling infectious diseases. However, reports about the role of serum soluble Tim-3 (sTim-3) in hepatitis virus infection are limited. Therefore, this study explored changes in sTim-3 levels in patients infected with hepatitis B virus (HBV), hepatitis C virus (HCV), and hepatitis E virus (HEV).MethodsThis study applied high-sensitivity time-resolved fluorescence immunoassay for the detection of sTim-3 levels. A total of 205 cases of viral hepatitis infection (68 cases of HBV infection, 60 cases of HCV infection, and 77 cases of HEV virus infection) and 88 healthy controls were quantitatively determined. The changes in serum sTim-3 level and its clinical value in hepatitis virus infection were analyzed.ResultsPatients with HBV infection (14.00, 10.78–20.45 ng/mL), HCV infection (15.99, 11.83–27.00 ng/mL), or HEV infection (19.09, 10.85–33.93 ng/mL) had significantly higher sTim-3 levels than that in the healthy control group (7.69, 6.14–10.22 ng/mL, P < 0.0001). Patients with hepatitis and fibrosis infected with HBV (22.76, 12.82–37.53 ng/mL), HCV (33.06, 16.36–39.30 ng/mL), and HEV (28.90, 17.95–35.94 ng/mL) had significantly higher sTim-3 levels than patients with hepatitis without fibrosis (13.29, 7.75–17.28; 13.86, 11.48–18.64; 14.77, 9.79–29.79 ng/mL; P < 0.05).ConclusionsTim-3 level was elevated in patients infected with HBV, HCV, or HEV and gradually increased in patients with either hepatitis or hepatitis with hepatic fibrosis. It has a certain role in the evaluation of the course of a disease after hepatitis virus infection.

Abstract
BACKGROUND Abdominal aortic aneurysm (AAA) shrinkage after endovascular aortic aneurysm repair (EVAR) is a surrogate marker for successful exclusion. Our study characterized aneurysm sac remodeling after EVAR to identify a pattern that may be associated with benign AAA behavior and would safely allow a less rigorous follow-up regimen after EVAR. METHODS Elective infrarenal EVARs performed between 2008 and 2011 at our institution were retrospectively reviewed. AAA sac diameters using the minor axis measurement from ultrasound imaging or computer tomography angiogram imaging were compared with the baseline diameter from the 1-month postoperative computer tomography angiogram. The primary outcome was a composite of freedom from postoperative reintervention or rupture. We compared those with AAA sacs who regressed to predefined minimum diameter thresholds with those who did not. Outcomes were plotted with Kaplan-Meier curves and compared using log-rank testing and Fine-Gray regression using death as a competing risk, clustered on graft type. For patients whose AAA reached the minimum sac diameter, landmark analysis evaluated ongoing size changes including further regression and sac re-expansion. RESULTS A total of 540 patients (aged 75.1 ± 8.2 years; 82.0% male) underwent EVAR with an average preoperative AAA size of 55.2 ± 11.5 mm. The median postoperative follow-up was 5.3 years (interquartile range, 1.4-8.7 years) during which 64 patients underwent reintervention and 4 ruptured. AAA sac regression to ≤40 mm in diameter was associated with improved freedom from reintervention or rupture overall (log-rank, P < .01), which was maintained after controlling for the competing risk of death (P < .01). In 376 patients (70%) whose aneurysm sac remained >40 mm, 99 reinterventions were performed on 63 patients. Of 166 (31%) patients whose sac regressed to ≤40 mm, only 1 patient required a reintervention, and no one ruptured. The mean time to a diameter of ≤40 mm was 2.3 ± 1.9 years. Only eight patients (5%) developed sac re-expansion to >45 mm; all but two occurred at least 3 years after initially regressing to ≤40 mm. CONCLUSIONS In long-term follow-up, patients whose minimum AAA sac diameter regressed ≤40 mm after EVAR experienced a very low rate of reintervention, rupture, or sac re-expansion. Most sac re-expansion occurred at least 3 years after reaching this threshold and did not result in clinical events. Increasing follow-up frequency up to 3-year intervals once the AAA sac regresses to 40 mm would carry minimal risk of aneurysm-related morbidity.

Increased sensitivity of gp210 autoantibody detection using a newly designed gp210 antigen. J Immunol Methods 2021; 501:113211. [PMID: 34971632 DOI: 10.1016/j.jim.2021.113211] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/23/2021] [Revised: 12/09/2021] [Accepted: 12/23/2021] [Indexed: 10/19/2022]
Abstract
OBJECTIVES The detection of autoantibody to glycoprotein 210 (gp210 Ab) against a 15 amino-acid peptide epitope by enzyme-linked immunosorbent assay (ELISA) has been widely used in the diagnosis of primary biliary cholangitis (PBC). However, this small peptide antigen presents spatial limitations for antibody access, which reduces the sensitivity of autoantibody detection. A recombinant gp210 antigen was constructed for increased sensitivity in antibody detection is described here. METHODS The gp210 C terminal 18 amino acid coding sequence was ligated to the modified C-terminal 108 amino acid coding sequence of human serum albumin (mHSA108) and produced as a recombinant gp210 antigen mHSA108-gp210-C18. Measurements of gp210 Ab using the gp210 C-terminal 25 amino acid peptide (gp210-C25) and mHSA108-gp210-C18 by in-house ELISA were compared. ELISAs with mHSA108-gp210-C18 and commercial INOVA kit for gp210 Ab detection were also compared in PBC patients and healthy controls. The correlation between the two assays was analyzed and their efficiency in diagnosing was compared. RESULTS Of 86 PBC samples, 35 (40.70%) and 44 (52.33%) positive samples were detected for anti-gp210 Ab using gp210-C25 and mHSA108-gp210-C18, respectively. Of 252 samples from PBC, 114 (45.24%) were positive for mHSA108-gp210-C18 ELISA whereas 94 (37.3%) for commercial ELISA (INOVA). All positive samples detected with commercial ELISA kit were also tested positive in mHSA108-gp210-C18 ELISA. Among 374 patients with other autoimmune diseases, anti-gp210 Ab were detected by mHSA108-gp210-C18 ELISA in 0.95% systemic lupus erythematosus (SLE) patients (2/210), 13.04% rheumatoid arthritis (RA) patients (13/97), and 1.47% of Sjögren's Syndrome (SS) patients (1/67). CONCLUSIONS Compared to the gp210 peptide antigen, the sensitivity of the ELISA system using mHSA108-gp210-C18 antigen was improved. The novel gp210 antigen could be useful for screening patients known to be at increased risk of developing PBC.

Abstract
To form a stable emulsion system, the water-soluble proteins (WSPs) of Sipunculus nudus were prepared as the sole effective stabilizer for the high internal phase emulsion (HIPEs), of which the influence of the WSPs concentration and environmental stability was investigated. The HIPEs were fabricated using a simple one-pot homogenization process (10,000 rpm/min, 3 min) that involved blending the WSPs (0.1, 1, 2, 3, 4, and 5 wt%) with soybean oil (60, 65, 70, 75, 80, 85, and 90%). The microstructure and properties of stable HIPEs were characterized by particle size, ζ-potential, visual observations, optical microscopy, and dynamic rheology property measurements. As the concentration of WSPs increases, the mean particle diameter of HIPEs decreases, on the contrary, the apparent viscosity and storage modulus gradually increase. At a given emulsifier concentration (3 wt%), the stable and gel-like HIPEs were formed at the oil internal phase (ϕ) values of 70–75%, all the pH range in values from 3 to 9, and the ionic strength from 100 to 500 mM. Furthermore, the HIPEs that were stabilized formed a gel-like state that was relatively stable to heat and storage (30 days). And there was a new phenomenon that the destabilized HIPE of the freeze-thaw treatments could still return to a gel-like state again after homogenizing. The study results suggest that the WSPs of S. nudus as a natural emulsifier could be widely used in the food industry.

Abstract
Objective: To investigate the safety and efficacy of stereotactic-EEG (SEEG)-guided radiofrequency thermocoagulation (RF-TC) with three-dimensional lesioning in the treatment of drug-resistant insular epilepsy. Methods: Seven patients with drug-resistant insular epilepsy who underwent SEEG-guided RF-TC with three-dimensional ablation at the Department of Neurosurgery of Xuanwu Hospital, Capital Medical University from February 2017 to June 2019 were retrospectively enrolled. Presurgical evaluation including semiology, EEG and imaging results suggested that the epileptogenic zone was located in the insular lobe. All patients underwent SEEG recording and three-dimensional RF-TC. Postoperative follow-up was conducted by outpatient visits or telephone, the clinical efficacy was evaluated based on Engel classification and the relevant complications were documented. Results: Seven patients were followed up at 18 months after surgery. Among them, 4 were seizure free (Engel ⅠA), 2 had nondisabling simple partial seizures (Engel ⅠB) and 1 achieved 75% decrease (Engel ⅢA) in seizure frequency. Postoperative complications occurred in 3 patients which included decreased sensation in the right lower extremity, decreased strength in the right upper extremity, glossolalia, decline in memory and comprehension. No permanent neurological dysfunction was detected. Conclusion: SEEG-guided RF-TC with three-dimensional lesioning is minimally invasive, safe and effective in the treatment of drug-resistant insular epilepsy and can serve as a complementary method for resection surgery.

Abstract
OBJECTIVE To explore the role of cell cycle checkpoint kinase 1/2 (CHK1/2) in mediating the inhibitory effect of oxymatrine (OMT) against renal inflammation and fibrosis in diabetic rats. METHODS SD rats were randomly divided into normal control group, diabetes model group (DM) and OMT treatment group (n=6). HE and Masson staining were used to observe histopathological changes of the renal tissue, and the expressions of CHK1, CHK2, p-CHK1 and p-CHK2 were localized by immunohistochemical staining. The contents of interleukin-6 (IL-6) and IL-1β in the renal tissue were detected using ELISA, and the expression levels of CHK1, CHK2, p-CHK1, p-CHK2, type Ⅲ collagen (Col-Ⅲ), type Ⅳ collagen (Col-Ⅳ), and fibronectin (FN) were determined using Western blotting. The changes in the expressions of CHK1, CHK2, p-CHK1, p-CHK2, Col-Ⅲ, Col-Ⅳ and FN proteins were also examined with Western blotting in NRK-52E cells in response to high glucose exposure, OMT treatment and siRNA-mediated CHK1/2 knockdown. RESULTS In diabetic rats, OMT treatment significantly decreased the levels of blood glucose, serum creatinine and 24 h urinary protein (P < 0.05) and obviously improved inflammatory cell infiltration and fibrosis phenotype in the renal tissue (P < 0.05). CHK1 and CHK2 were mainly expressed in the cytoplasm and nuclei of renal tubule cells, and their phosphorylation levels were significantly higher in DM group than in the control group and OMT group. OMT treatment significantly decreased the protein expression levels of p-CHK1, p-CHK2, Col-Ⅲ, Col-Ⅳ and FN in the renal tissue of diabetic rats and in NRK-52E cells exposed to high glucose (P < 0.05). In NRK-52E cells, CHK1/2 knockdown resulted in significant reduction of the protein expressions of p-CHK1/2, Col-Ⅲ, Col-Ⅳ and FN (P < 0.05). CONCLUSION The inhibitory effects of OMT against renal inflammation and fibrosis in diabetic rats are mediated probably by lowered phosphorylation levels of CHK1 and CHK2, which result in reduced release of the downstream inflammatory mediators and decreased secretion and deposition of extracellular matrix.
