PURPOSE The appropriate object thickness to start using anti-scatter grids (grids) has not sufficiently investigated in previous studies, and thus we rigorously investigated the effectiveness of two generally used grids with grid ratios of 6 and 10 (G6 and G10) for different 50-200 mm thicknesses at tube voltages of 60-100 kV. METHODS Acrylic phantoms with 30 × 30 cm2 and different thicknesses were used to measure the signal-to-noise ratio improvement factors (SIFs) of grids. To evaluate the infants' conditions, field sizes of 225, 400, and 625 cm2 were also evaluated at 60-80 kV. In addition, the signal difference-to-noise ratio (SDNR) was used to evaluate tube voltage dependencies of grids for each thickness. RESULTS SIF values exceeded 1.0 for ≥70 mm thicknesses and mostly exceeded 1.07 for the 100 mm thickness with 400 cm2 field size corresponding to a 1-year-old infant abdomen. The estimated dose reduction capabilities for a 1-year-old infant were approximately 15% using G10 at 70 and 80 kV. The tube voltage dependencies for grid use was almost not prominent for all conditions tested, except for some conditions that are not clinically realistic. CONCLUSIONS G6 and G10 can improve SNR for ≥100 mm thickness. The results from this work demonstrate approximately 15% dose reduction or image quality improvements at the same dose level for the use of G6 and G10 grids for 100 mm thickness, traditionally excluded from the recommended grid use conditions. BACKGROUND Although partial meniscectomy is a common treatment for the tears in the avascular region of the meniscus, mechanical alterations following meniscectomy are known to initiate mechanically-induced osteoarthritis. We aimed to measure the articular cartilage contact pressure distributions in the knees with surgically repaired and partially resected menisci in the avascular region. METHODS A pneumatic loading device was developed to apply a 1000 N compressive load on the cadaveric porcine knee samples at the flexion angles of 20, 35, 50, and 65°. We simulated longitudinal meniscal tears in the avascular inner 1/3 portion and the well-vascularized middle 1/3 portion of the meniscus. Articular cartilage contact pressures for the knees with intact, torn, repaired, and resected menisci were compared. FINDINGS For the tears in well-vascularized regions, meniscal repairs restored articular cartilage contact pressures to the levels in intact joints. However, partial meniscectomy significantly increases the maximum contact pressures and the average contact pressures in highly compressed areas. However, partial meniscectomy in the avascular region did not alter the maximum articular cartilage contact pressures and the average contact pressures in highly compressed areas. Stabilities in knee samples were not significantly altered following partial meniscectomy in both inner and middle regions. INTERPRETATION Although repair surgeries are beneficial for the tears in well-vascularized areas because the articular cartilage contact mechanics are reconstructed, partial meniscectomy may be a viable alternative treatment for the tears in avascular regions without introducing significant mechanical alterations. This study aimed to investigate the protective effect of GanodericacidA (GA) on myocardial ischemia-reperfusion (MIR) injury. The myocardial injury model in rats was established by ligating left anterior descending coronary artery. We measured cardiac hemodynamic, antioxidant enzyme activity, and various biochemical indexes of myocardial tissue, and evaluated myocardial infarction and damage. Further, the expression of JAK2/STAT3/NF-κB signaling pathway-related proteins in myocardial tissue was measured by western blot. The results showed that the myocardial infarction extention was obviously reduced upon GA treatment. Compared with the control group, ischemia-reperfusion rats showed significant increase in lactate dehydrogenase (LDH) and creatine Kinase (CK), which were significantly decreased in GA group. Besides, GA pretreatment effectively decreased the levels of inflammatory cytokines in serum. The phosphorylation of Janus Kinase 2 (JAK2), signal transducer and activator of transcription (STAT3)and Nuclear factor-κB (NF-κB) in reperfusion group were significantly higher than that in control group, which were reversed upon GA treatment. In conclusion, GA may reduce myocardial injury by regulating JAK2/STAT3/NF-κB pathway. Inflammatory bowel disease is one of the major causes of colitis-associated colon cancer (CAC). Therefore, it is necessary to explore new therapies to prevent colon cancer (CRC) in view of the relationship between chronic inflammation and tumor development. Previous studies on the correlation between CD30L/CD30 and cancer were mostly limited to lymphoid or homogenous tumors, while there have been only a few reports on the role of CD30L/CD30 signal transduction in the pathogenesis of CAC. In this study, we established an AOM/DSS-induced CAC model with CD30LKO mice to explore the effect of CD30L/CD30 signal transduction on the formation of the intestinal tumor immune microenvironment (TIME) during the development of intestinal tumors. Our results revealed that CD30L deficiency promoted the accumulation of myeloid derived suppressor cells (MDSCs), increased the expression of PD-L1 on MDSCs and tumor associated macrophages (TAMs), and enhanced the secretion of various inflammatory and immunosuppressive factors in the intestinal mucosa of CAC mice. Furthermore, CD30L gene deletion could selectively promote the upregulation of PD-1 expression on CD4+ and CD8+ T cells and inhibit their activation, differentiation and secretion of effector cytokines, which led to an attenuation of antitumor immune responses mediated by TEM (CD44+CD62L-) cells. Thus, our data suggest that CD30L/CD30 signaling might be a potential candidate target for immunological therapy in CAC. Alzheimer's disease (AD) is one of the most prevalent neurodegenerative diseases characterized by the formation of extracellular amyloid beta (Aβ) plaques and intracellular neurofibrillary tangles (NFTs). Growing evidence suggested that there is an association between neuronal dysfunction and neuroinflammation (NI) in AD, coordinated by the chronic activation of astrocytes and microglial cells along with the subsequent excessive generation of the proinflammatory molecule. Therefore, a better understanding of the relationship between the nervous and immune systems is important in order to delay or avert the neurodegenerative events of AD. The inflammatory/immune pathways and the mechanisms to control these pathways may provide a novel arena to develop new drugs in order to target NI in AD. In this review, we represent the influence of cellular mediators which are involved in the NI process, with regards to the progression of AD. We also discuss the processes and the current status of multiple anti-inflammatory agents which are used in AD and have gone through or going through clinical trials. PARP activity Moreover, new prospects for targeting NI in the development of AD drugs have also been highlighted. Alopecia areata (AA) is a common alopecia characterized by non-scarring hair loss with the dysregulated immunity. However, the pathogenesis of AA remains to be elucidated. In this study, we identified gene signatures and then analyzed transcription factor-immune regulatory network in AA using integrated bioinformatics methods. Finally, we verified potential target genes in lesions of AA patients using qPCR and immunohistochemistry. Here, 74 differentially expressed genes (DEGs) were identified in AA, which were enriched in immune-related signaling pathway. The immune analysis revealed the infiltration of γδT cells and Macrophages M1 in AA lesion. Next, the expression correlation analysis and ChIP-seq results revealed a transcription factor (EOMEs) regulated network. We found that EOMEs, a T-box transcription factor, may be involved in the immunoregulation in AA via targeting CD8A and BMP2, and it may affect keratinocytes function via regulating GZMK, LYPD6, RNF182, KRTAP5-9 and KRT73 expression. Finally, the mRNA expression of these network genes in AA lesions was confirmed using qPCR. And the increase expression of EOMEs was identified at inflammatory cells at the periphery of hair follicles and partial keratinocytes in AA tissue using immunohistochemistry. In conclusions, our research demonstrated that EOMEs may play a key role in the progression of AA via regulating immune cell infiltration and keratinocytes function, indicating EOMEs as a promising therapeutic target of AA. BACKGROUND Vladimiriae Radix (VR) is the dry root of Vladimiria souliei (Franch.) Ling or Vladimiria souliei (Franch.) Ling var. cinerea Ling. Costunolide (CO) and dehydrocostus lactone (DE) are the two most effective active ingredients of VR. Raw Vladimiriae radix (rVR) and processed Vladimiriae radix (pVR) are the two most common forms. They have been used for hundreds of years to treat gastritis, gastric ulcer and gastrointestinal pain, but their protective effects on gastric mucosa have been widely considered to be different, and the mechanism is not clear. PURPOSE A comparative study of in vivo process and efficacy difference of raw and processed Vladimiriae Radix was carried out to explore the treatment mechanism and to provide reference for the rationality of clinical usage. METHODS In this study, multi-batch rVR and pVR were used to establish the characteristic chromatograms through high performance liquid chromatography (HPLC) to control the qualities of their extracts. A rapid and accurate ultra-hig inhibit the expression of NF-κB p65, IκBα and up-regulate the expression of HO-1 and NRF2 more operatively to protect gastric mucosa through anti-inflammatory and antioxidant stress mechanisms. CONCLUSION Compared with rVR, pVR has an accelerated absorption in vivo and its effect time was prolonged, and the observed improvement of anti-AGMI effect was achieved through anti-oxidation and anti-inflammation regulation. Seed biopriming is an emerging technique to enhance seed germination under stress conditions. An integrated approach of tomato seed biopriming with ascorbic acid, Trichoderma asperellum BHU P-1 and Ochrobactrum sp. BHU PB-1 was applied to observe the response against wilt pathogen of tomato Fusarium oxysporum f. sp. lycopersici (FOL). Tomato seeds bioprimed with the aforementioned application expressed augmented seed germination and activated of defense response. Seed germination was recorded higher (80 %) at low concentration (1 pM) of ascorbic acid as compared to high concentration of 1 mM (41 %). Combination of both ascorbic acid and antagonistic microbe treatments (T5 & T6) significantly reduced disease incidence (up to 28 %) in tomato plants at 10 days. T5 and T6 treated plants exhibited higher accumulation of total phenol content and increased activity of Phenylammonia lyase (PAL), Peroxidase (PO), Chitinase (Chi) and Polyphenol oxidase (PPO) as compared to control (T1) plants. ROS formation in the form of H2O2 was also found to be reduced in combined treatment. Histochemical analysis revealed that phenylpropanoid pathway (lignin deposition) was more activated in combined priming treatment plants as compared to individual treatment upon challenge inoculation with FOL. Transcript expression analysis of defense genes confirmed the up-regulation of PAL (2.1 fold), Chi (0.92 fold), Pathogenesis related proteins (PR) (1.58 fold) and Lipoxygenase (Lox) (0.72 fold) in T6 treatment as compared to T1 treatment plants at 96 h. This study reveals that ascorbic acid treatment with antagonistic microbes through seed priming effectively induced seed germination and elicited defense mechanism to control wilt disease in tomato plants.
