Validity of the EOS-determined pelvic parameters and orientation with pelvic positional variation: a phantom study

AbstractThe EOS is a medical imaging system that incorporates simultaneous orthogonal images, producing three-dimensional (3D) reconstructions of the whole skeletal system in various functional positions. Despite growing interest in the pelvic 3D position, the validity of the EOS has not yet been well studied. We investigated the trueness and precision of EOS imaging for pelvic parameters and orientation and assessed whether the measurement using the EOS was affected by the pelvic orientation itself. The orientation of the anterior pelvic plane and pelvic parameters of a custom-made pelvic phantom were measured by three raters using the EOS, and the measurements obtained were compared with the true values. The standard deviations of the measurement errors were 3.23°, 0.26°, 0.23°, 2.98°, 0.88°, and 3.22° for flexion, obliquity, rotation, pelvic incidence, spinopelvic tilt, and sacral slope, respectively. The root-mean square averages of the standard deviation of each measurement were 4.05°, 0.41°, 0.28°, 4.80°, 0.99°, and 5.13°, respectively. The measurement errors for sacral slope correlated significantly with geometric means of flexion, obliquity, and rotation (r = 0.364, p = 2.67 × 10–11). The EOS rendered accurate and reliable measurements regarding pelvic 3D position, even with positional variation, but positional variation could affect measurements of sacral slope.</jats:p

Anti-inflammatory Activities and Component Change of Processed and Fermented Gastrodiae Rhizoma

Abstract Gastrodiae Rhizoma (GR) is a traditional herbal medicine in Korea, China, and Japan, which has been used for the treatment of headaches, hypertension, oxidative stress, mental disorders, inflammation, and cardiovascular diseases. This study investigated the anti-infammatory activity and main component content of processed (PGR) and fermented Gastrodiae Rhizoma (FPGR). Processed method was soaked in vinegar solution until completely absorbed and steaming for 2 hours. Fermentation was carried out using Lactobacillus brevis and incubated at 37□ for 1~3 day. The anti-inflammatory activites were determine pro-inflammatory factors such as nuclear factor κB (NF-κB), nitric oxide (NO), prostaglandin E2 (PGE2), inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) in lipopolysaccharide (LPS)-induced RAW 264.7 cell line and major functional components (gastrodin, gastrodigenin, vanillylalcohol, p-hydroxybenzaldehyde) were also measured. The results showed that the FPGR reduced NO, PGE2, iNOS, COX-2, NF-κB production without cytotoxicity and improved major components. These results suggest that FPGR extracts may be a developed the functional food related to anti-inflammation due to the significant effects on inflammatory facters. Therefore, fermented and processed Gastrodiae Rhizoma can be useful methods which can help applied as functional resources in the industrial area.</jats:p

The capicua-ataxin-1-like complex regulates Notch-driven marginal zone B cell development and sepsis progression

Abstract Follicular B (FOB) and marginal zone B (MZB) cells are pivotal in humoral immune responses against pathogenic infections. MZB cells can exacerbate endotoxic shock via interleukin-6 secretion. Here we show that the transcriptional repressor capicua (CIC) and its binding partner, ataxin-1-like (ATXN1L), play important roles in FOB and MZB cell development. CIC deficiency reduces the size of both FOB and MZB cell populations, whereas ATXN1L deficiency specifically affects MZB cells. B cell receptor signaling is impaired only in Cic-deficient FOB cells, whereas Notch signaling is disrupted in both Cic-deficient and Atxn1l-deficient MZB cells. Mechanistically, ETV4 de-repression leads to inhibition of Notch1 and Notch2 transcription, thereby inhibiting MZB cell development in B cell-specific Cic-deficient (Cic f/f ;Cd19-Cre) and Atxn1l-deficient (Atxn1l f/f ;Cd19-Cre) mice. In Cic f/f ;Cd19-Cre and Atxn1l f/f ; Cd19-Cre mice, humoral immune responses and lipopolysaccharide-induced sepsis progression are attenuated but are restored upon Etv4-deletion. These findings highlight the importance of the CIC-ATXN1L complex in MZB cell development and may provide proof of principle for therapeutic targeting in sepsis

Rationally Designed Eugenol-Based Chain Extender for Self-Healing Polyurethane Elastomers

Bio-based polyurethane (PU) has recently drawn our attention due to the increasing interest in sustainability and the risks involved with petroleum depletion. Herein, bio-based self-healing PU with a novel polyol, i.e., eugenol glycol dimer (EGD), was synthesized and characterized for the first time. EGD was designed to have pairs of primary, secondary, and aromatic alcohols, which all are able to be involved in urethane bond formation and to show self-healing and antioxidant effects. EGD was incorporated into a mixture of the prepolymer of polyol (tetramethylene ether glycol) and 4,4′-methylene diphenyl diisocyanate to synthesize PU. EGD-PU showed excellent self-healing properties (99.84%), and it maintained its high self-healing property (84.71%) even after three repeated tests. This dramatic self-healing was induced through transcarbamoylation by the pendant hydroxyl groups of EGD-PU. The excellent antioxidant effect of EGD-PU was confirmed by 2,2-diphenyl-1-picrylhydrazyl analysis. Eugenol-based EGD is a promising polyol chain extender that is required in the production of bio-based, self-healing, and recyclable polyurethane; therefore, EGD-PU can be applied to bio-based self-healable films or coating materials as a substitute for petroleum-based PU

Short-Term Effects of Weight-Loss Meal Replacement Programs with Various Macronutrient Distributions on Gut Microbiome and Metabolic Parameters: A Pilot Study

It has emerged the gut microbiome is crucially linked to metabolic health and obesity. Macronutrient distribution has been discussed as a key parameter in weight-loss programs, but little is known about its impact on the gut microbiome. We investigated the effects of weight-loss meal replacement programs with different macronutrient ratios on the gut microbiota and metabolic parameters in subjects with overweight and obesity. Three low-calorie meal replacement programs with different ratios of carbohydrates, proteins, and lipids were designed: a balanced diet (Group B, 60:15:30), a high-lipid&minus;low-carbohydrate diet (Group F, 35:20:55), and a protein-enriched diet (Group P, 40:25:35). Sixty overweight or obese participants were provided with the meals twice daily for 3 weeks. In all groups, diet intervention resulted in reduced body weight and BMI. The relative abundance of Bacteroidetes and Firmicutes phyla decreased and increased, respectively, which increased the Firmicutes/Bacteroidetes (F/B) ratio in all subjects, particularly in Groups B and P. Alpha- and beta-diversity were augmented at the phylum level in Group P. In conclusion, short-term interventions with weight-loss meal replacement programs increased butyrate-producing bacteria and the F/B ratio. Moreover, the protein-enriched diet significantly increased alpha- and beta-diversity compared to the balanced diet and the high-lipid&minus;low-carbohydrate diet

Improving adaptive behaviors for autistic adults without intellectual disability through executive function training

Executive functioning (EF) is a cognitive process used to perform various daily activities throughout one's lifespan. Autistic adults without intellectual disabilities (ID) also experience difficulties with EF, which is closely associated with adaptive behaviors. For this reason, it is important to improve adaptive behaviors through enhanced use of EF for autistic adults to transition into adulthood successfully. This study aims to conduct a randomized controlled trial to evaluate the effectiveness of a newly developed and modified intervention program. Thirty autistic adults without ID were randomly assigned to the treatment or waitlist group. The participants and caregivers completed various assessments and self-report questionnaires to measure everyday EF and adaptive behaviors. We performed linear mixed-effect modeling to compare the two groups. Data collected at pre-, middle, post-, and follow-up based on participants who completed the program were used to explore changes across time. While there were significant differences in the EF utility-scale (F=5.46, p = .027) between the treatment and waitlist groups, no group x time interactions were detected in other measures. Everyday EF and adaptive behaviors improved when comparing measurements at different time points (p < .001). Our program is Korea's first evidence-based intervention to improve everyday EF and adaptive behaviors for autistic adults without ID.•Found improvements in everyday EF and adaptive behaviors among autistic adults without ID.•An intervention with contents applicable and translational to daily life situations.•First evidence-based intervention to improve EF in autistic adults without ID in Korea.•One of the rare RCTs of behavioral intervention for autistic adults without ID

An Intervention Program Targeting Daily Adaptive Skills Through Executive Function Training for Adults with Autism Spectrum Disorder: A Pilot Study

Objective Adults with autism spectrum disorders (ASD) experience significant difficulties with executive functioning (EF) and related adaptive skills, yet the lack of interventions in South Korea targeting these areas has resulted in a heightened need to develop an evidence- based program. Therefore, we developed a novel intervention aiming to enhance everyday EF and daily adaptive skills in adults with high-functioning ASD and conducted a pilot study to evaluate the validity and feasibility of the program. Methods A behavioral intervention of 10-weekly sessions was developed based on literature searches and focus group interviews. Seven adults with high-functioning ASD (mean age=20.29) participated in a single-group pilot trial. We used self and parent-report questionnaires as well as skills measured by assessment instruments to analyze differences before and after the intervention. Results Significant improvements were shown in everyday EF, including time management, organization, self-restraint, and regulation of emotions. Additionally, results demonstrated an enhancement in adaptive functioning, especially in the subdomains of daily living skills. Analyses of parental outcomes only revealed a significant decrease in the scores of emotion regulation. Conclusion The current study provides good evidence for the validity and feasibility of an intervention to improve everyday EF and adaptive skills in adults with ASD.</jats:p
