RESUMO

BACKGROUND: Hot flashes are a common side effect of endocrine therapy (ET) that contribute to poor quality of life and decreased treatment adherence. METHODS: Patients with breast cancer wo were receiving ET and experiencing hot flashes were enrolled through three parallel, randomized trials conducted in the United States, China, and South Korea. Participants were randomized to either immediate acupuncture (IA) or delayed acupuncture control (DAC). IA participants received 20 acupuncture sessions over 10 weeks, whereas DAC participants received usual care, then crossed over to acupuncture with a reduced intensity. The primary end point was a change in score on the endocrine symptom subscale of the Functional Assessment of Cancer Therapy (FACT)-Endocrine Symptoms between baseline and week 10. Secondary end points included the hot flash score and the FACT-Breast score. A planned pooled analysis of individual patient data was performed using longitudinal mixed models. RESULTS: In total, 158 women with stage 0-III breast cancer were randomized (United States, n = 78; China, n = 40; South Korea, n = 40). At week 10, IA participants reported statistically significant improvements in the endocrine symptom subscale score (mean change ± standard error: 5.1 ± 0.9 vs. 0.2 ± 1.0; p = .0003), the hot flash score (-5.3 ± 0.9 vs. -1.4 ± 0.9; p < .003), and the FACT-Breast total score (8.0 ± 1.6 vs. -0.01 ± 1.6; p = .0005) compared with DAC participants. The effect of the acupuncture intervention differed by site (p = .005). CONCLUSIONS: Acupuncture led to statistically and clinically meaningful improvements in hot flashes, endocrine symptoms, and breast cancer-specific quality of life in women undergoing ET for breast cancer in the United States, China, and South Korea.

RESUMO

OBJECTIVE: An experiment was conducted to investigate the response of laying hens fed corn distiller's dried grains with solubles (DDGS) that are naturally contaminated with deoxynivalenol (DON). METHODS: One hundred and sixty 52-week-old Lohmann Brown Lite hens were randomly allotted to five dietary treatments with 8 replicates per treatment. The dietary treatments were formulated to provide a range of corn DDGS contaminated with DON from 0% to 20% (i.e., 5% scale of increment). All laying hens were subjected to the same management practices in a controlled environment. Body weight, feed intake and egg production were measured biweekly for the entire 8-week experiment. The egg quality was measured biweekly for 8 weeks. On weeks 4 and 8, visceral organ weights, blood metabolites, intestinal morphology, and blood cytokine concentrations were measured. RESULTS: The inclusion of corn DDGS contaminated with DON in the diet did not alter (p> 0.05) the body weight, feed intake, hen-day egg production, egg mass and feed efficiency of the laying hens. No difference was found (p>0.05) in the egg quality of hens that were fed the dietary treatments. Furthermore, hens that were fed a diet containing corn DDGS contaminated with DON showed no change (p>0.05) in the visceral organ weights, the blood metabolites, and the cytokine concentrations. The crypt depth increased (p<0.05) as the amount of corn DDGS contaminated with DON increased. Proportionately, the villus height to crypt depth ratio of the laying hens decreased (p<0.05) with the increasing level of corn DDGS contaminated with DON in the diet. CONCLUSION: The inclusion of corn DDGS contaminated with DON up to 20% in layer diets did not cause changes in egg production performance and egg quality, which indicates that DON is less toxic at the concentration of 1.00 mg DON/kg.

RESUMO

Patients with Parkinson's disease (PD) are liable to experience impairment in their activities of daily living (ADL), which include ambulating, eating, dressing, bathing, and personal hygiene. The aim of this study is to assess which clinical characteristics contribute significantly to instrumental ADL (IADL) in PD patients without dementia. We included 106 PD patients in our study, and each patient's motor and non-motor status and basic and instrumental ADL were assessed using the appropriate scales. Of the 106 PD patients, 31 (29.2%) had abnormal Korean IADL (K-IADL) scores. These patients were older and had higher scores in terms of the modified Hoehn and Yahr (mHY) staging scale, Unified Parkinson's Disease Rating Scale (UPDRS) parts II and III, UPDRS part IV motor fluctuation, Beck Depression Inventory (BDI), and total Non-Motor Symptoms assessment scale for PD (NMSS), as well as lower scores in the Mini-Mental State Examination (MMSE). Pearson's correlation analysis showed significant associations between the scores of K-IADL and each of the following characteristics of the patients: age, mHY stage, UPDRS parts II and III, UPDRS part IV motor fluctuation, BDI, total NMSS, and MMSE. Multivariate linear regression analysis showed that the significant clinical characteristics associated with the K-IADL scores were determined to be the UPDRS part II, MMSE, and BDI scores. The results of our study revealed that the cognitive, depression, and motor symptoms were the significant predictors of IADL in PD patients without dementia.

RESUMO

BACKGROUND: Freezing of gait (FOG) is a common and debilitating problem in patients with Parkinson's disease (PD). The aim of this study was to estimate the prevalence of FOG, and to identify factors that independently contribute to FOG in patients with PD. METHOD: We included 157 PD patients. FOG was assessed using the FOG Questionnaire (FOG-Q). Patients with or without FOG were defined as item 3 in the FOG-Q. RESULTS: One hundred eleven (70.7%) out of 157 PD patients presented with FOG. Patients with FOG were older, had long disease duration, were taking higher doses of dopaminergic agents, and had higher motor and non-motor scores than those without FOG. Multivariate linear regression analysis showed that high modified Hoehn and Yahr (mHY) stage, Unified PD Rating Scale (UPDRS) part II score, and non-motor symptom assessment scale for PD (NMSS) total score were significant predictors of a high FOG-Q score. Patients with FOG had significantly higher scores for cardiovascular, gastrointestinal tract, urinary, and miscellaneous NMSS domains than those without FOG. CONCLUSIONS: FOG in PD was associated with higher mHY stage, UPDRS part II score, and total NMSS score. Therefore, clinicians should consider non-motor, motor features and activities of daily living states for the proper management of FOG.

RESUMO

As senescence develops, cells sequentially acquire diverse senescent phenotypes along with simultaneous multistage gene reprogramming. It remains unclear what acts as the key regulator of the collective changes in gene expression at initiation of senescent reprogramming. Here we analyzed time series gene expression profiles obtained in two different senescence models in human diploid fibroblasts: replicative senescence and H2O2-induced senescence. Our results demonstrate that suppression of DNA methyltransferase 1 (DNMT1)-mediated DNA methylation activity was an initial event prior to the display of senescent phenotypes. We identified seven DNMT1-interacting proteins, ubiquitin-like with PHD and ring finger domains 1 (UHRF1), EZH2, CHEK1, SUV39H1, CBX5, PARP1, and HELLS (also known as LSH (lymphoid-specific helicase) 1), as being commonly down-regulated at the same time point as DNMT1 in both senescence models. Knockdown experiments revealed that, among the DNMT1-interacting proteins, only UHRF1 knockdown suppressed DNMT1 transcription. However, UHRF1 overexpression alone did not induce DNMT1 expression, indicating that UHRF1 was essential but not sufficient for DNMT1 transcription. Although UHRF1 knockdown effectively induced senescence, this was significantly attenuated by DNMT1 overexpression, clearly implicating the UHRF1/DNMT1 axis in senescence. Bioinformatics analysis further identified WNT5A as a downstream effector of UHRF1/DNMT1-mediated senescence. Senescence-associated hypomethylation was found at base pairs -1569 to -1363 from the transcription start site of the WNT5A gene in senescent human diploid fibroblasts. As expected, WNT5A overexpression induced senescent phenotypes. Overall, our results indicate that decreased UHRF1 expression is a key initial event in the suppression of DNMT1-mediated DNA methylation and in the consequent induction of senescence via increasing WNT5A expression.

RESUMO

OBJECTIVE: The Fusarium mycotoxins of deoxynivalenol (DON) and zerolenone (ZEN) cause health hazards for both humans and farm animals. Therefore, the main intention of this study was to reveal DON and ZEN effects on the mRNA expression of pro-inflammatory cytokines and other immune related genes in the liver of piglets. METHODS: In the present study, 15 six-week-old piglets were randomly assigned to the following three different dietary treatments for 4 weeks: control diet, diet containing 8 mg DON/kg feed, and diet containing 0.8 mg ZEN/kg feed. After 4 weeks, liver samples were collected and sequenced using RNA-Seq to investigate the effects of the mycotoxins on genes and gene networks associated with the immune systems of the piglets. RESULTS: Our analysis identified a total of 249 differentially expressed genes (DEGs), which included 99 upregulated and 150 downregulated genes in both the DON and ZEN dietary treatment groups. After biological pathway analysis, the DEGs were determined to be significantly enriched in gene ontology terms associated with many biological pathways, including immune response and cellular and metabolic processes. Consistent with inflammatory stimulation due to the mycotoxin-contaminated diet, the following Kyoto encyclopedia of genes and genomes pathways, which were related to disease and immune responses, were found to be enriched in the DEGs: allograft rejection pathway, cell adhesion molecules, graft-versus-host disease, autoimmune thyroid disease (AITD), type I diabetes mellitus, human T-cell leukemia lymphoma virus infection, and viral carcinogenesis. Genome-wide expression analysis revealed that DON and ZEN treatments downregulated the expression of the majority of the DEGs that were associated with inflammatory cytokines (interleukin 10 receptor, beta, chemokine [C-X-C motif] ligand 9), proliferation (insulin-like growth factor 1, major facilitator superfamily domain containing 2A, insulin-like growth factor binding protein 2, lipase G, and salt inducible kinase 1), and other immune response networks (paired immunoglobulin-like type 2 receptor beta, Src-like-adaptor-1 [SLA1], SLA3, SLA5, SLA7, claudin 4, nicotinamide N-methyltransferase, thyrotropin-releasing hormone degrading enzyme, ubiquitin D, histone H2B type 1, and serum amyloid A). CONCLUSION: In summary, our results demonstrated that high concentrations DON and ZEN disrupt immune-related processes in the liver.

RESUMO

BACKGROUND: Pain and osteoporosis are common in Parkinson's disease (PD), and lower bone mineral density (BMD) or osteoporosis may be associated with an increased risk of reporting to have pain in the general population. The aim of this study was to determine whether there is an association between the pain subtypes and the BMD in patients with PD. METHODS: We included 162 PD patients. Pain was assessed using the patients' descriptions, a structured interview, a detailed neurologic examination, and the Visual Analogue Scale. BMD was measured using dual energy X-ray absorptiometry scans. RESULTS: Of the 162 PD patients, 120 had chronic pain, while 42 reported no pain. The most prevalent type of pain was musculoskeletal, followed by radicular/neuropathic, dystonic, and central. PD patients with musculoskeletal pain had a lower BMD than PD patients without pain. Multivariate regression analysis showed that the low BMD of the lumbar spine, hip, and femoral neck were related to old age, female gender, low MBI, and the presence of musculoskeletal pain. CONCLUSION: PD patients with musculoskeletal pain have low BMD and are at risk for developing osteoporosis. If a PD patient has musculoskeletal pain and other risk factors related to low BMD, clinicians should consider screening for osteoporosis.

RESUMO

BACKGROUND: Acorus gramineus has been reported to exhibit various pharmacological effects including inhibition of cholesterol synthesis, enhancement of lipid metabolism, prevention of dementia and inhibition of mast cell growth. According to the Chinese compendium of materia media, it has been reported that Acorus spp. is effective for sedation, dementia prevention as well as diuretic effect. In addition, it showed more than equivalent activity compared to furosoemide, a drug known to be effective in diuretic action in animal model study. However, their effectiveness against benign prostatic hyperplasia (BPH) of Acorus gramineus has not been reported. This study was designed to evaluate the effect of Acorus gramineus root hot water extract (AG) against BPH in vivo. METHODS: Male rats, 10 weeks of age and weighing 405 g ± 10 g, were used for this study. Biomarkers were evaluated including prostate weight, prostate weight ratio, hormonal changes, 5-α reductase type II androgen receptor (AR) of the prostate gland and anti-oxidant activation factors related to BPH. These biomarkers were measured in vivo test. RESULTS: AG showed significant effect at the 250 and 500 mg/kg/day in rats. Groups treated with AG displayed significantly lower levels of prostate gland weight (0.79 g) compared to the BPH induced group (1.19 g). Also, dihydrotestosterone (DHT) level was decreased from 61.8 to 100% and androgen receptor expression level was decreased from 111 to 658%. Any hematological toxicity of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) level wasn't observed. CONCLUSION: This study indicated that AG was effective for reducing BPH symptoms. TRIAL REGISTRATION: Not applicable.

RESUMO

Bile acids (BAs) are pleiotropic regulators of metabolism. Elevated levels of hepatic and circulating BAs improve energy metabolism in peripheral organs, but the precise mechanisms underlying the metabolic benefits and harm still need to be fully understood. In the current study, we identified orosomucoid 2 (ORM2) as a liver-secreted hormone (i.e., hepatokine) induced by BAs and investigated its role in BA-induced metabolic improvements in mouse models of diet-induced obesity. Contrary to our expectation, under a high-fat diet (HFD), our Orm2 knockout (Orm2-KO) exhibited a lean phenotype compared with C57BL/6J control, partly due to the increased energy expenditure. However, when challenged with a HFD supplemented with cholic acid, Orm2-KO eliminated the antiobesity effect of BAs, indicating that ORM2 governs BA-induced metabolic improvements. Moreover, hepatic ORM2 overexpression partially replicated BA effects by enhancing insulin sensitivity. Mechanistically, ORM2 suppressed interferon-γ/STAT1 activities in inguinal white adipose tissue depots, forming the basis for anti-inflammatory effects of BAs and improving glucose homeostasis. In conclusion, our study provides new insights into the molecular mechanisms of BA-induced liver-adipose cross talk through ORM2 induction.

RESUMO

Transforming growth factor ß1 (TGF ß1) induces Mv1Lu cell senescence by persistently producing mitochondrial reactive oxygen species (ROS) through decreased complex IV activity. Here, we investigated the molecular mechanism underlying the effect of TGF ß1 on mitochondrial complex IV activity. TGF ß1 progressively phosphorylated the negative regulatory sites of both glycogen synthase kinase 3 (GSK3) α and ß, corresponding well to the intracellular ROS generation profile. Pre-treatment of N-acetyl cysteine, an antioxidant, did not alter this GSK3 phosphorylation (inactivation), whereas pharmacological inhibition of GSK3 by SB415286 significantly increased mitochondrial ROS, implying that GSK3 phosphorylation is an upstream event of the ROS generation. GSK3 inhibition by SB415286 decreased complex IV activity and cellular O(2) consumption rate and eventually induced senescence of Mv1Lu cell. Similar results were obtained with siRNA-mediated knockdown of GSK3. Moreover, we found that GSK3 not only exists in cytosol but also in mitochondria of Mv1Lu cell and the mitochondrial GSK3 binds complex IV subunit 6b which has no electron carrier and is topologically located in the mitochondrial intermembrane space. Involvement of subunit 6b in controlling complex IV activity and overall respiration rate was proved with siRNA-mediated knockdown of subunit 6b. Finally, TGF ß1 treatment decreased the binding of the subunit 6b to GSK3 and subunit 6b phosphorylation. Taken together, our results suggest that GSK3 inactivation is importantly involved in TGF ß1-induced complex IV defects through decreasing phosphorylation of the subunit 6b, thereby contributing to senescence-associated mitochondrial ROS generation.

RESUMO

Objective: The objective of this study is to compare the microbiome of healthy peri-implant sulcus (C) and peri-implantitis sulcus (U) from the same patient and analyze the difference in the microbiome composition. Materials and methods: DNA samples of subgingival biofilms from 10 C (control group) and 10 U (uncontrolled group) sites were sent to Microbiome Center in Korea Research Institute of Biomedical Science and analyzed using 16s rRNA gene amplification and sequencing (MiSeq, Illumina) and human oral microbiome database (HOMD). Results: At the phylum level, Firmicutes and Proteobacteria were more abundant in group C, while Firmicutes and Bacteroidetes were dominant in group U. At the genus level, the core peri-implant microbiome was Streptococcus in group C. On the other hand, the core peri-implant microbiome was Porphyromonas, especially P. gingivalis in group U. Conclusion: In this study, the microbiome composition of peri-implantitis sulcus was different from that of healthy peri-implant sulcus from the same patient. The peri-implantitis microbiome was pathogen-enriched and was similar to the microbiome associated with periodontitis.

RESUMO

The objective was to determine the effects of drying and blanching methods on the nutrient utilization of black soldier fly larva (BSFL; Hermetia illucens) meal by pigs using in vitro assays. Two-step and three-step in vitro assays were employed to simulate the gastrointestinal tract of pigs. Four BSFL meals were prepared using the following pretreatment methods: (1) microwave drying at 80 °C for 32 min, (2) hot-air drying at 60 °C for 17 h, (3) blanching for 5 min in boiling water and hot-air drying at 60 °C for 17 h, and (4) 2% citric acid solution blanching for 5 min in boiling solution and hot-air drying at 60 °C for 17 h. After the drying process, each BSFL was defatted and ground to obtain BSFL meals. The nitrogen (N) concentration in the test ingredients ranged from 8.5 to 9.4%, and the ether extract ranged from 6.9 to 11.5% on an as-is basis. The amino acid (AA) concentration in the BSFL meals ranged from 2.80 to 3.24% for Lys and 0.71 to 0.89% for Met on an as-is basis. Hot-air-dried BSFL meal had a greater in vitro ileal disappearance (IVID) of N compared with microwave-dried BSFL meal (p < 0.05). However, blanched BSFL meals in water or 2% citric acid solution before hot-air drying had a lower (p < 0.05) IVID of N compared with microwave-dried or hot-air-dried BSFL meal. Blanched BSFL meals in water or 2% citric acid solution before hot-air drying showed a lower (p < 0.05) in vitro total tract disappearance of dry matter and organic matter compared with microwave-dried or hot-air-dried BSFL meal. Microwave-dried BSFL meal had a lower (p < 0.05) IVID of indispensable AA, except for His, Lys, Met, and Phe, compared with hot-air-dried BSFL meals. However, blanched BSFL meals in water or 2% citric acid solution before hot-air drying showed a lower (p < 0.05) IVID of indispensable AA compared with microwave-dried or hot-air-dried BSFL meal. In conclusion, hot-air-dried BSFL meal presented greater nutrient utilization compared with microwave-dried BSFL meal for pigs. However, blanching in water or citric acid solution negatively affected the nutrient digestibility of BSFL meal based on in vitro assays.

RESUMO

This study aimed to evaluate the effects of dietary Chlorella vulgaris (CV) on the distribution of immune cells, intestinal morphology, intestinal barrier function, antioxidant markers, and the cecal microbiome in 10-day-old broiler chickens. A total of 120 day-old Ross 308 male broiler chicks were assigned to two dietary treatments using a randomized complete block design, with body weight as the blocking factor. Birds fed a diet containing CV showed an increase in CD4+ T cells (p < 0.05) compared to those fed the control diet. The relative mRNA expression of intestinal epithelial barrier function-related markers (occludin and avian ß-defensin 5) was elevated (p < 0.05) in the CV-supplemented group compared to the control group. The alpha diversity indices (Chao1 and observed features) of the cecal microbiome in 10-day-old birds increased (p < 0.05), indicating higher richness within the cecal bacterial community. In the microbiome analysis, enriched genera abundance of Clostridium ASF356 and Coriobacteriaceae CHKCI002 was observed in birds fed the diet containing CV compared to those fed the control diet. Taken together, dietary CV supplementation might alter intestinal barrier function, immunity, and microbiomes in 10-day-old broiler chickens.

RESUMO

Caspase cleavage of amyloid precursor protein (APP) has been reported to be important in amyloid beta protein (Aß)-mediated neurotoxicity. However, the underlying mechanisms are not clearly understood. In this study, we explored the effect of caspase cleavage of APP on tau phosphorylation in relation to Aß. We found that Asp664 cleavage of APP increased tau phosphorylation at Thr212 and Ser262 in N2A cells and primary cultured hippocampal neurons. Compared with wild-type APP, protein phosphatase 2A (PP2A) activity was significantly increased when Asp664 cleavage was blocked by the D664A point mutation. Furthermore, we found that over-expression of C31 reduced PP2A activity. C31 binds directly to the PP2A catalytic subunit, through the asparagine, proline, threonine, tyrosine (NPTY) motif, which is essential for C31-induced tau hyperphosphorylation. However, it appears that the other fragment produced by Asp664 cleavage, Jcasp, modulates neither PP2A activity nor tau hyperphosphorylation. Asp664 cleavage and accompanying tau hyperphosphorylation were remarkably diminished by blockage of Aß production using a γ-secretase inhibitor. Taken together, our results suggest that Asp664 cleavage of APP leads to tau hyperphosphorylation at specific epitopes by modulating PP2A activity as a downstream of Aß. Direct binding of C31 to PP2A through the C31-NPTY domain was identified as a mechanism underlying this effect.

RESUMO

BACKGROUND: We aimed to comparatively analyze the effect of integrative medicine treatments (lifestyle change education, use of anti-inflammatory drugs, acupuncture, manual therapy-type massage) and conventional medical treatments (lifestyle change education and use of anti-inflammatory drugs) on pain control, knee function improvement, and quality of life improvement in patients with degenerative knee arthritis. METHODS: In this study, 30 patients were randomly divided into the control group (n = 15) and the experimental group (n = 15). Both groups were prescribed anti-inflammatory drugs and lifestyle change education for 12 weeks. The experimental group underwent acupuncture including electroacupuncture, moxibustion, and manual therapy-type massage 12 times during the first 6 weeks. Evaluations were performed at 3 visits: visit 1 (before treatment), visit 2 (6 weeks after initial treatment), and visit 3 (12 weeks after initial treatment). The effect of each treatment was measured using Visual Analog Scale (VAS, 0-10), Western Ontario and McMaster Universities index (WOMAC), and SF-36. RESULTS: From visit 1 to visit 2, the mean value of VAS decreased by 0.72 and 3.17 in the control and experimental groups, respectively. From visit 2 to visit 3, the mean VAS value decreased by 0.25 in the control group but increased by 0.87 in the experimental group. Among the sub-area of SF-36, the physical role restriction area and mental health area showed significant differences between the 2 groups over time (P = .024, P = .006). CONCLUSION: Integrative medicine treatment has superior effects in pain control over conventional medical treatment. In integrative medicine treatment, pain control tends to decrease with time, but still superior over conventional medical treatment up to 6 weeks after treatment (12 weeks after initial treatment).

RESUMO

BACKGROUND: Acupuncture has been reported to reduce hot flashes in patients with breast cancer undergoing adjuvant hormonal therapy. Although hot flashes are common, the prevalence varies among cultures, races, and ethnicities; the efficacy of acupuncture across cultures has not been investigated. METHODS: This is a coordinated multinational study, including three parallel randomized trials with a planned analysis of individual patient data, to test the effectiveness of acupuncture on hot flash-related symptoms in hormone receptor-positive breast cancer patients on adjuvant endocrine therapy. Using a standardized acupuncture protocol (total across all three studies of n = 80) versus usual care (total n = 80), symptoms are assessed using changes in the Endocrine Symptom Subscale of Functional Assessment of Cancer Therapy-Endocrine Symptoms. Secondary outcomes include hot flash severity, quality of life, and sleep quality. Differences in response to acupuncture between participants in the three countries will also be explored. DISCUSSION: Here we describe the design of a protocol for a coordinated multinational study, with attention to the complex considerations in developing a multinational research effort testing a non-pharmacologic intervention. This protocol and approach provide guidance for future efforts to evaluate and test non-pharmacologic interventions across multinational populations. TRIAL REGISTRATION: clinicaltrials.gov (Identifier: NCT00797732, registered on December 21, 2018), Chinese Clinical Trial Registry (ChiCTR2100045888), and The Clinical Research Information Service (CRIS) of Korea (Registration number: KCT0003618).

RESUMO

BACKGROUND: Mood disorder is a frequent complication of stroke. Comorbid depressive and anxiety disorders are very common, indicating that it is advisable to assess both disorders at the same time. The aim of the present study was to examine the prevalence of post-stroke depression (PSD) and poststroke anxiety (PSA) at baseline and to evaluate factors related to delayed PSD and PSA at 3 months after stroke onset. METHODS: This was a prospectively registered and retrospectively analyzed study of patients with acute ischemic stroke between January 2009 and March 2010. Patients included in this study were interviewed in order to evaluate their Hospital Anxiety and Depression Scale (HADS) scores. In this study, each depression and anxiety score was dichotomized into 'nondepressive and nonanxious' (HADS-D and HADS-A ≤7) and 'depressive and anxious' (HADS-D and HADS-A >7). Multiple logistic regression analysis was used to evaluate the independent factors of depressive and anxious symptoms 3 months after stroke onset. RESULTS: Of the 133 patients, 47.4% were 'depressive' and 56.4% were 'anxious' at baseline. The depressive and anxious groups had a significantly higher frequency of severe white matter hyperintensity (WMH) than the nondepressive and nonanxious groups (p < 0.05). The independent factors of PSD and PSA at 3 months were deep white matter hyperintensities (DWMH) and modified Rankin scale 0 to 1 at 3 months. CONCLUSION: In conclusions, the results of our study demonstrated that delayed depression and anxiety after ischemic stroke were related to the severity of DWMH and unfavorable outcomes at 3 months, regardless of anti-anxiety treatment. Our results suggested that WMH might be associated with pathomechanism of delayed depression and anxiety.

RESUMO

Lipase (EC 3.1.1.3) is a popular enzyme used as an ingredient in detergents and biocatalyst in many biochemical reactions. Lipase is usually expressed in Escherichia coli as an inactive inclusion body and at a low level. In this study, Candida antarctica lipase B (CalB) was fused with various polycationic amino acid tags and expressed in E. coli in order to increase a soluble expression level. By induction with 1.0 mM IPTG, the authentic and fused CalBs were expressed at 27-56% of total protein. The 10-arginine and 10-lysine tags fused at the C-terminal of CalB significantly increased the solubility of CalB by five- to ninefold, relative to the case of the authentic CalB expressed in a recombinant E. coli Origami 2™ (DE3) strain. Among a series of the C-terminal poly-arginine tags, the recombinant CalB combined with the 10-arginine tag (CalB-R10) possessed the highest lipase specific activity of 9.5 ± 0.03 U/mg protein, corresponding to a fourfold enhancement compared with the authentic CalB.

RESUMO

The objective of this study was to find out if suppression of NF-kB complex function by p65-TMD-linked PTD could reduce host inflammation and bone resorption at peri-implantitis sites in rats. Twenty-one male 5-week-old SD rats were divided into three groups: untreated control group (A), silk-induced peri-implantitis group (B), and nt (nucleus transducible)-p65-TMD-treated, silk-induced peri-implantitis group (C). Implant sulcus of a rat in group C were divided into two groups, namely group Cp and Cb. Palatal implant sulcus where nt-p65-TMD solution was applied with an insulin syringe were assigned to group Cp. Buccal implant sulcus without topical nt-p65-TMD application were assigned to group Cb. H&E staining, TRAP staining, and immunohistological staining were done. The crestal bone levels of group A were significantly higher than those of group B at p<0.01. The crestal bone levels of group Cp were significantly higher than those of group Cb at p<0.05. H-E staining showed increased apical migration of junctional epithelium and inflammatory cells in group Cb. TRAP staining revealed more multinucleated osteoclasts in group Cb. As for immunohistological staining, group Cb showed many IL-6-positive cells while group Cp had none. In this study, p65-TMD-linked PTD inhibited NF-kB functions and reduced inflammation and bone resorption at peri-implantitis sites in rats.

RESUMO

OBJECTIVE: Deoxynivalenol (DON) and zearalenone (ZEN) are mycotoxins that frequently contaminate maize and grain cereals, imposing risks to the health of both humans and animals and leading to economic losses. The gut microbiome has been shown to help combat the effects of such toxins, with certain microorganisms reported to contribute significantly to the detoxification process. METHODS: We examined the cecum contents of three different dietary groups of pigs (control, as well as diets contaminated with 8 mg DON/kg feed or 0.8 mg ZEN/kg feed). Bacterial 16S rRNA gene amplicons were acquired from the cecum contents and evaluated by next-generation sequencing. RESULTS: A total of 2,539,288 sequences were generated with ~500 nucleotide read lengths. Firmicutes, Bacteroidetes, and Proteobacteria were the dominant phyla, occupying more than 96% of all three groups. Lactobacillus, Bacteroides, Megasphaera, and Campylobacter showed potential as biomarkers for each group. Particularly, Lactobacillus and Bacteroides were more abundant in the DON and ZEN groups than in the control. Additionally, 52,414 operational taxonomic units were detected in the three groups; those of Bacteroides, Lactobacillus, Campylobacter, and Prevotella were most dominant and significantly varied between groups. Hence, contamination of feed by DON and ZEN affected the cecum microbiota, while Lactobacillus and Bacteroides were highly abundant and positively influenced the host physiology. CONCLUSION: Lactobacillus and Bacteroides play key roles in the process of detoxification and improving the immune response. We, therefore, believe that these results may be useful for determining whether disturbances in the intestinal microflora, such as the toxic effects of DON and ZEN, can be treated by modulating the intestinal bacterial flora.
