Development and characterization of a dedicated dose monitor for ultrahigh-dose-rate scanned carbon-ion beams. Sci Rep 2024; 14:11574. [PMID: 38773165 PMCID: PMC11109334 DOI: 10.1038/s41598-024-62148-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2023] [Accepted: 05/14/2024] [Indexed: 05/23/2024] Open
Abstract
The current monochromatic beam mode (i.e., uHDR irradiation mode) of the scanned carbon-ion beam lacks a dedicated dose monitor, making the beam control challenging. We developed and characterized a dedicated dose monitor for uHDR-scanned carbon-ion beams. Furthermore, a simple measurable dose rate (dose rate per spot (DRspot)) was suggested by using the developed dose monitor and experimentally validating quantities relevant to the uHDR scanned carbon-ion beam. A large plane-parallel ionization chamber (IC) with a smaller electrode spacing was used to reduce uHDR recombination effects, and a dedicated operational amplifier was manufactured for the uHDR-scanned carbon-ion beam. The dose linearity of the IC was within ± 1% in the range of 1.8-12.3 Gy. The spatial inhomogeneity of the dose response of the IC was ± 0.38% inside the ± 40-mm detector area, and a systematic deviation of approximately 2% was measured at the edge of the detector. uHDR irradiation with beam scanning was tested and verified for different doses at the corresponding dose rates (in terms of both the average dose rate and DRspot). We confirmed that the dose monitor can highlight the characteristics (i.e., dose, dose rate, and dose profile) of uHDR-scanned carbon-ion beams at several dose levels in the monochromatic beam mode.

Validity of a preoperative scoring system for surgical management of periprosthetic hip infection: one-stage vs. two-stage revision. Arch Orthop Trauma Surg 2024:10.1007/s00402-024-05279-5. [PMID: 38662000 DOI: 10.1007/s00402-024-05279-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Accepted: 03/10/2024] [Indexed: 04/26/2024]
Abstract
INTRODUCTION There are no widely accepted algorithms for determining optimal treatment for periprosthetic joint infection (PJI). Our study aimed to confirm the validity of a previously published scoring system in a larger number of patients to support a rational surgical treatment strategy for periprosthetic hip infection. MATERIALS AND METHODS Between February 2001 and December 2020, we performed 155 consecutive revision total hip arthroplasties (THAs) for PJI, with mean follow-up of 6 years. One-stage revision THA was performed in 56 hips and two-stage revision THA in 99 hips. Prosthesis survival from recurrent infection was determined by Kaplan-Meier analysis, using implant removal as the endpoint. The pre-operative scoring system (full score of 12 points), including 6 essential elements, was retrospectively evaluated. RESULTS The 10-year survival rates were 98% for one-stage (95% confidence interval [CI], 94-100) and 87% (95% CI, 79-96) for two-stage revision THA. Multivariate Cox regression analysis provided a total preoperative score as an independent risk factor for implant removal (hazard ratio, 0.17; 95% CI, 0.06-0.49; p < 0.001). The sensitivity and specificity at the cut-off of 4 points on the scoring system were 80% and 91%, respectively. The average score for one-stage revision THA in successful and failed cases were 8.9 and 6.0, and for two-stage revision THA were 6.5 and 3.9, respectively. We found significant differences between successful cases in one- and two-stage revision THA (p < 0.05). CONCLUSIONS The preoperative scoring system was useful for managing PJI. One-stage revision THA is recommended in patients scoring ≥ 9 points, and meticulously performed two-stage revision THA is encouraged for patients scoring ≥ 4 points.

Can serum C-reactive protein determine the timing of reimplantation in two-stage revised arthroplasty for periprosthetic hip infection? J Orthop Sci 2023:S0949-2658(23)00194-X. [PMID: 37507315 DOI: 10.1016/j.jos.2023.07.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/20/2023] [Revised: 07/10/2023] [Accepted: 07/14/2023] [Indexed: 07/30/2023]
Abstract
BACKGROUND There are no definitive guides to determine the timing of reimplantation in two-stage revision total hip arthroplasties (THA) for periprosthetic joint infection (PJI). This study was to design to support a rational strategy of surgical treatment using serum C-reactive protein (CRP). METHODS We analyzed a total of 75 hips for PJI in the process of performing two-stage and multiple-stage revision THAs. CRP level was retrospectively evaluated every week and transformed to log2 (CRP) using a logistic regression model. Prosthesis survival from recurrent infection was determined by Kaplan-Meier analysis, using implant removal as the endpoint. Receiver operating characteristic curves were calculated using each log2 (CRP) to assess predictions of recurrent infection. RESULTS The 10-year survival rates were 85% (95% confidence interval, 76-95) and 100% for two-stage and multiple-stage revision THAs, respectively. Preoperatively, at 1, 2, 3, and 5 weeks, log2 (CRP) was not associated with recurrent infection. In failed two-stage revision THAs, log2 (CRP) at 3 weeks divided by that at 2 weeks showed a significant difference. Failure was associated with a ratio of >4.0 for the CRP level between 3 and 2 weeks. CONCLUSION In two-stage revision THA for PJI, patients with CRP elevation from 2 weeks to 3 weeks, especially 4-fold elevation, suggests the need for further debridement and postponement of second-staged reimplantation.

Treatment strategies for recurrent dislocation following total hip arthroplasty: relationship between cause of dislocation and type of revision surgery. BMC Musculoskelet Disord 2023; 24:238. [PMID: 36991409 PMCID: PMC10053790 DOI: 10.1186/s12891-023-06355-4] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/21/2022] [Accepted: 03/21/2023] [Indexed: 03/30/2023] Open
Abstract
Abstract
Background
There are many therapeutic options for dislocation following total hip arthroplasty (THA). The aim of this study was to evaluate the results of revision surgery for dislocated hips.
Methods
Between November 2001 and December 2020, 71 consecutive revision hip surgeries were performed at our institution for recurrent dislocation following THA. We conducted a retrospective study of all 65 patients (71 hips), who were followed for a mean of 4.7 ± 3.2 years (range, 1–14). The cohort included 48 women and 17 men, with a mean age of 71 ± 12.3 years (range, 34–92). The mean number of previous surgeries was 1.6 ± 1.1 (range, 1–5). From intraoperative findings, we created six categories of revision hip surgery for recurrent dislocation following THA: open reduction and internal fixation (2 hips); head change or liner change only (6 hips); cup change with increased head size only (14 hips); stem change only (7 hips); cup and stem change (24 hips); and conversion to constrained cup (18 hips). Prosthesis survival was analyzed by the Kaplan-Meier method, with repeat revision surgery for re-dislocation or implant failure as the endpoint. A cox proportional hazards model was used for risk factors of re-revision surgery.
Results
Re-dislocation occurred in 5 hips (7.0%) and implant failure in 1 hip (1.4%). The 10-year survival rate was 81.1% (95% confidence interval, 65.5–96.8). A Dorr classification of “positional” was a risk factor for re-revision surgery due to re-dislocation.
Conclusion
Clear understanding of the cause of dislocation is essential for optimizing revision procedures and improving the rate of successful outcomes.

Abstract
Background The removal of a well-fixed cementless stem poses technical challenges. The aim of this study was to evaluate the outcomes of our endofemoral extraction technique established in 2001. Methods Between January 2001 and December 2016, 118 consecutive revisions following bipolar or total hip arthroplasty, which required cementless femoral stem removal, were performed at our institution. This retrospective study evaluated 106 patients (108 hips) who were followed up for a mean of 9.2 years (range, 5-20 years). The patients included 15 men and 91 women with a mean age of 65 years (range, 33-87 years). Endofemoral extracted stem removal was performed as follows. Multiple Kirschner wires were sequentially inserted into the interface between the implant and cortical bone, after which the implant was detached using a thin chisel. After the cementless stem was removed, it was replaced with a cemented stem using an autograft, as needed. Radiological loosening of the femoral stem was defined as definite or probable loosening, based on the criteria of Harris et al. Prosthesis survival was analyzed using the Kaplan-Meier method, with the endpoint set as repeat revision surgery for stem loosening or femoral fracture. Results Re-revision surgery was performed in 7 hips. Stem loosening was observed in 4 hips, and the mean subsidence was 0.3 mm (0-3 mm). The 10-year survival rate was 97.7% (95% confidence interval, 93.2-100). Conclusions Our technique for removing well-fixed cementless stems yielded successful results.

Abstract
BackgroundAge strongly influences cognitive ability. Previous studies have tried to compare the cognitive ability of people with different immune mediated inflammatory diseases (IMIDS: systemic lupus erythematosus [SLE], rheumatoid arthritis [RA], axial spondyloarthritis [axSpA], psoriatic arthritis [PsA], psoriasis [PsO]) in age-matched analyses. However, given the varying age of onset of these conditions, within direct age-matched comparisons one of the disease groups is necessarily older/younger than typical.Objectives(i) To perform a systematic review of the cognitive ability of people with IMIDs compared with age-matched controls, and (ii) use meta-regression to indirectly compare the cognitive ability of people with different IMIDs.MethodsA search strategy was implemented in the Medline, Embase and PsychInfo databases on 29.5.2021. Identified studies were screened by two reviewers, selecting observational studies comparing the cognitive ability of people with an IMID against healthy controls. This abstract only includes studies reporting overall cognition scores, memory scores and attention scores. The standardised mean differences (SMDs) of the cognitive assessments between people with IMIDs and controls were pooled using random-effects meta-analysis, stratified by IMID. The IMIDs were compared using meta-regression, to identify the IMID with the greatest impairment in cognitive ability compared with healthy people of a similar age (inclusion cut-off: ≥5 studies).ResultsIn total, 62 studies (SLE: 37, RA: 18, axSpA: 1, PsA: 2, PsO: 4) were included in the meta-analyses. People with IMIDs had moderate impairments in overall cognition, memory and attention compared with controls (Table 1), with similar results seen when limiting analyses to studies which included age-matched controls (N=48 studies). People with SLE and RA had similar levels of impairment compared with controls of comparable age in terms of overall cognition (coef: -0.12 (95% CI -0.42, 0.19) and attention (coef: -0.35 (95% CI -0.73, 0.04)). Other IMIDs and cognition dimensions were not included in the meta-regression analysis due to lack of studies.Table 1.Results of meta-analysesStandardised mean difference (95% Confidence Interval) [N studies]Systemic lupus erythematosusRheumatoid arthritisAxial spondyloarthritisPsoriatic arthritisPsoriasisOverall cognitionAll-0.55 (-0.70. -0.39) [18]-0.59 (-0.82, -0.35) [13]-0.66 (-1.11, -0.21) [1]-0.50 (-0.78, -0.21) [2]-0.51 (-1.09, 0.07) [3]Age-matched-0.55 (-0.72, -0.38) [14]-0.66 (-0.92, -0.41) [11]-0.66 (-0.11, -0.21) [1]-0.61 (-1.08, -0.14) [1]-0.77 (-1.39, -0.16) [2]AttentionAll-0.51 (-0.63, -0.38) [27]-0.79 (-1.10, -0.47) [9]-0.58 (-1.03, -0.13) [1]--0.14 (-0.42, 0.14) [2]Age-matched-0.51 (-0.67, -0.36) [21]-0.87 (-1.35, -0.39) [6]-0.58 (-1.03, -0.14) [1]--0.36 (-0.75, 0.04) [1]Verbal memory (immediate)All-0.59 (-0.79, -0.38) [19]-1.00 (-1.47, -0.53) [7]---0.52 (-1.05, 0.02) [3]Age-matched-0.61 (-0.90, -0.32) [12]-1.42 (-1.73, -1.12) [4]---0.72 (-1.42, -0.02) [2]Verbal memory (delayed)All-0.44 (-0.57, -0.31) [18]-0.93 (-1.48, -0.38) [5]-0.23 (-0.67, 0.21) [1]--0.52 (-1.52, 0.49) [2]Age-matched-0.39 (-0.56, -0.21) [12]-1.40 (-1.76, -1.03) [3]-0.23 (-0.67, 0.21) [1]--1.05 (-1.47, -0.63) [1]Non-Verbal memory (immediate)All-0.41 (-0.57, -0.25) [15]-0.32 (-1.23, 0.58) [1]-0.21 (-0.62, 0.23) [1]--Age-matched-0.34 (-0.52, -0.16) [10]--0.21 (-0.62, 0.23) [1]--Non-Verbal memory (delayed)All-0.45 (-0.63, -0.27) [16]-0.41 (-0.91, 0.08) [1]-0.14 (-0.58, 0.30) [1]--Age-matched-0.46 (-0.75, -0.17) [10]-0.41 (-0.91, 0.08) [1]-0.14 (-0.58, 0.30) [1]--ConclusionPeople with IMIDs have significant impairments in terms of overall cognition, memory and attention. Whilst this indirect analysis shows that people with SLE and RA have a similar magnitude of impairment compared with healthy controls of a similar age, a number of factors could be influencing this finding (e.g. selection bias, demographic differences).Disclosure of InterestsNone declared

Abstract
The rare decay K_{L}→π^{0}νν[over ¯] was studied with the dataset taken at the J-PARC KOTO experiment in 2016, 2017, and 2018. With a single event sensitivity of (7.20±0.05_{stat}±0.66_{syst})×10^{-10}, three candidate events were observed in the signal region. After unveiling them, contaminations from K^{±} and scattered K_{L} decays were studied, and the total number of background events was estimated to be 1.22±0.26. We conclude that the number of observed events is statistically consistent with the background expectation. For this dataset, we set an upper limit of 4.9×10^{-9} on the branching fraction of K_{L}→π^{0}νν[over ¯] at the 90% confidence level.

Abstract
A longer surgical time will lead to postoperative complications in orthopaedic surgery. According to previous reports, surgeon volume affects a surgical time in anterior cruciate ligament (ACL) reconstruction. However, little attention has been paid to difference of a surgical time between high- and low-volume surgeons in ACL reconstruction. The purpose of the present study was to investigate the surgical time for both high- and low-volume surgeons and to clarify technical obstacles as well as the important technique to reduce the surgical time in ACL reconstruction. A total of 103 knees in 103 patients with ACL tear were enrolled. All the procedures were performed by 13 different surgeons. The surgeons were divided into two surgeon groups (high- and low-volume groups) based on the number of annual cases. The operative technique was divided into the same five steps to perform comparisons of step-by-step surgical time between the surgeon groups of different volumes. The statistical comparison was done between high- and low-volume groups in terms of surgical time in each step. Total operation times were 87.8 ± 17.6 and 129.9 ± 42.9 minutes in high- and low-volume group, respectively. Low-volume surgeons took much time in tendon harvesting and bone tunnel creation using arthroscopy. Low-volume surgeons took more time for primary ACL reconstruction, especially in tendon harvesting, compared with high-volume surgeons. Tendon harvesting was extremely important, as well as bone tunnel creation, for low-volume surgeons to reduce surgical time in primary ACL reconstruction.

Abstract
Background:The risk of cognitive decline and dementia is of particular interest for patients exposed to prolonged inflammation. In rheumatoid arthritis (RA), the inflammatory mechanisms that are central to the disease’s pathology share many features with those seen in Alzheimer’s disease (AD). However, published reports on the strength and direction of the putative associations with cognitive decline and dementia in RA are conflicting and the potential impact of immunomodulation has not been fully established. This study reports on a case control analysis comparing the results of a cognitive test conducted in RA cases from a longitudinal population register with healthy controls. The relationship between test outcomes, disease characteristics, and treatment is examined.Objectives:To characterise differences in cognitive function as assessed by a validated test battery between a group of patients with RA and a matched sample of healthy controls.To investigate disease and treatment related factors that might have an impact on the cognitive function of patients with RA.Methods:A total of 38 people with RA were selected at random from subjects who had enrolled on the Norfolk Arthritis Register as part of the ICORA (Investigation of Cognition in RA) Study. The register is a large longitudinal inception cohort of patients recruited from both primary and secondary care. The study subjects were over 55 years old with a diagnosis of RA defined by the ACR criteria. Cognitive function was assessed using the Addenbrooke’s Cognitive Examination III (ACE-III) battery. The ACE-III is a validated screening test for dementia that evaluates five cognitive domains (attention, memory, verbal fluency, language and visuospatial skills). A cut off value of 82 is indicative of cognitive impairment. The ACE-III scores in the cases were compared with scores from 29 healthy population-based controls matched for age and sex.Results:The mean age of the patient and control groups was 69 years. The RA patients had a mean disease duration of 9.8 years and had been taking DMARDs for 7.1 years. Among the patient group with RA, 14 (37%) scored below 82 compared with none in the group of healthy controls. The mean ACE-III scores of both groups are shown in the table below:Controls N=29RA N=38ACE-III Total95.2 (3.7)85.2 (7.4)•Attention17.7 (0.5)16.5 (1.9)•Memory24.6 (1.9)19.8 (4.0)•Fluency12 (1.4)9.9 (2.6)•Language25.5 (0.8)24.6 (1.7)•Visuospatial15.8 (0.5)14.4 (1.5)After adjusting for age, sex, BMI and smoking status, significant differences were seen in the ACE-III total (adjusted mean difference(SE)=8.67(1.77); p<0.001), memory (adjusted mean difference(SE)=4.16(1.03); p<0.001), fluency (adjusted mean difference(SE)=2.29(0.67); p=0.001) and visuospatial (adjusted mean difference(SE)=1.36(0.38); p<0.001). There was no difference in attention (p=0.19) or language (p=0.10).Among the patients with RA there was no clear association between disease duration and ACE-III Total scores; however, there was a trend for increasing cognitive scores in those who had been taking DMARDs for longer (<5 years: mean ACE-III Total=84.1; 5-10 years: 85.0: 11-14 years: 85.4; >14 years: 89.6).Conclusion:This study provides evidence to suggest that patients with established RA are at increased risk of cognitive decline when compared with healthy controls. The pattern of cognitive deficit, predominantly involving visuospatial and memory function, is consistent with an Alzheimer’s disease profile. Our data suggest a potential role for DMARDs in reducing the rate of cognitive decline in patients with RA.Disclosure of Interests:Tasuku Toyoda: None declared, Jacqueline Chipping: None declared, Jack Dainty: None declared, Stephen Jeffs: None declared, Michael Hornberger: None declared, Eneida Mioshi: None declared, Suzanne Verstappen Grant/research support from: BMS, Consultant of: Celltrion, Speakers bureau: Pfizer, Max Yates: None declared, Alex MacGregor: None declared

Abstract
BACKGROUND Cross-sensitivity of rash has been reported between various antiepileptic drugs (AEDs). However, few studies have determined the frequency and management of cross-sensitivity in patients with super-refractory status epilepticus (SRSE). AIMS OF THE STUDY To examine the optimal AED for treating SRSE with cross-sensitivity. METHODS We performed a retrospective review of adult patients with SRSE treated at Nagoya City University Hospital, in which we investigated the frequency of cross-sensitivity among patients with SRSE and their clinical and medical profiles. RESULTS We identified 10 adult patients with SRSE, 5 of whom had cross-sensitivity. Stiripentol (STP) was administered when previously used AEDs had demonstrated cross-sensitivity and failed to control seizures. After initiation of STP, the dose of general anaesthetics was reduced, and status epilepticus (SE) eventually ceased with co-administered AEDs without additional adverse effects. The mean time to SE cessation after initiation of STP was 30.8 days (range, 18-46 days), mean duration of general anaesthesia was 101.2 days (range, 74-128 days), and mean number of AEDs was 9.0 (range, 6-11). CONCLUSIONS This study suggests that cross-sensitivity between AEDs is common in adults with SRSE and that STP may be useful for treating SRSE with cross-sensitivity.

Abstract
Dye-sensitized solar cells (DSSCs) with reactive {001} facet-dominant TiO2 have attracted a great deal of attention owing to their high solar cell performance, despite the origin and the variation of the results being controversial. Here, we report the characteristic charge transport properties of DSSCs composed of {001} and {101} facet-dominant TiO2 nanoparticles in order to explain the origin of solar cell performance. Based on transient photocurrent and photovoltage measurements and transient absorption spectroscopy, the energetics of TiO2 semiconductors and dye sensitizers are utilized to understand the electron diffusion, recombination, and injection kinetics to determine solar cell performance. Novel strategies to improve DSSC performance by utilizing the characteristics of {001} facet-dominant TiO2 nanoparticles are proposed, which are (1) enhancement of electron injection and (2) reduction of carrier recombination for JSC and VOC improvement, despite the drawback of slower electron diffusion in the mesoporous network of {001} facet-dominant TiO2.

Abstract
Purpose: To clarify the Doppler sonographic features of the lingual artery in normal subjects and to evaluate those of patients with cancer of the tongue. Material and Methods: Sixty-seven volunteers and 12 patients with cancer and/or leukoplakia of the tongue were examined with an intraoral sonographic probe. The visibility of the deep lingual artery was determined on transverse and anteroposterior images. On the transverse images, the vascular index, which was defined as the number of colored pixels, was measured on bilateral lingual arteries. Thereafter, the degree of symmetry was evaluated for normal subjects and patients. Results: In normal subjects, between younger and older volunteers, there were no significant differences in visibility of the trunk but differences were found between the two groups for the dorsal branches. The vascular indices of the right and left sides were not different. The characteristic Doppler sonographic feature was vasculature in and around the tumors in the patients with cancer of the tongue. The symmetry indices of the cancer patients were significantly different from those of normal subjects. Conclusion: Doppler sonography should be an important procedure for evaluation of tongue neoplasms.

Abstract
Fowl glioma-inducing virus (FGV), which belongs to subgroup A of avian leukosis virus (ALV), shows tumorigenicity and pathogenicity, mainly in the nervous system, and causes astrocytoma and perineurioma. Apart from these neoplasms, cerebellar anomaly was found in chickens infected with FGV in ovo. The study reported here describes the morphologic characteristics of the affected cerebellum. Specific-pathogen-free chickens (C/O) were inoculated with FGV through the yolk sac on the 7th day of incubation. The cerebellar anomaly included diffuse depletion of granular cells of the internal granular layer (IGL), remnants of the external granular layer (EGL), and disorganization of the Purkinje cell layer. These cerebellar changes were observed in all birds except one. in the infected embryos, the EGL was thicker and had an irregular arrangement with a thin molecular layer (ML) and IGL, compared with the control. The granular cells were immunohistochemically positive for ALV common antigen. immunohistochemical analysis for vimentin revealed disarrangement and decreased number of Bergmann's fibers. Use of the terminal deoxynucleotidyl transferase-mediated dUTP-biotin nick end labeling method and electron microscopy indicated that apoptotic granular cells were frequently observed in the EGL and ML. These results suggested that the cerebellar anomaly was hypoplasia, principally resulting from the apoptosis of granular cells in the EGL and ML caused by FGV infection and that the cell loss induced obstruction of granular cell migration and disarrangement of Bergmann's fibers in the ML.

Abstract
Intraneural perineurioma is an extremely rare condition characterized by perineurial cell proliferation within peripheral nerve (PN) sheaths. In the veterinary field, this entity has been reported only in a dog. We examined multiple enlargements of PNs in 11 chickens ( Gallus gallus domesticus) (9 Japanese bantams and 2 specific pathogen-free White Leghorn), which were inoculated with an avian leukosis virus (ALV) causing so-called fowl glioma. All chickens clinically exhibited progressive leg paralysis. Lumbosacral plexus, brachial plexus, and/or spinal ganglion were commonly affected, and these nerves contained a diffuse proliferation of spindle cells arranged concentrically in characteristic onion bulb-like structures surrounded by residual axons and myelin sheaths. The spindle cells were immunohistochemically negative for S-100α/β protein. Electron microscopy revealed that these cells were characterized by short bipolar cytoplasmic processes, occasional cytoplasmic pinocytotic vesicles, and discontinuous basal laminae. These features are consistent with those of intraneural perineurioma. Furthermore, the specific sequence of the ALV was detected in the PN lesions of 8/11 (73%) birds by polymerase chain reaction. These results indicate that the multiple intraneural perineuriomas of chicken may be associated with the ALV-A causing fowl glioma.

Abstract
The TightRope RT (Arthrex, Naples, FL) is a suspensory device for anterior cruciate ligament reconstruction. However, there is a potential risk of the button being pulled too far off the lateral femoral cortex into the soft tissue because the adjustable loop is long. The purpose of this article is to present an easy and safe technique for self-flip. As to the preparation of the graft, we draw the first line in the loop of the TightRope RT at the same length as the femoral tunnel, and we draw the second line 7 mm longer than the length of the femoral tunnel as a self-flip line. Concerning passing of the graft, the side sutures are pulled from the lateral side. We stop pulling the sutures just at the self-flip line by holding the graft at the tibial end. The side suture is inclined to the medial side with strong pulling of the suture at full extension of the knee. Then the surgeon pulls the tibial end of the graft to feel a secure positioning of the button on the lateral femoral cortex. Although it has limitations, the present technique is easy and certainly helps surgeons achieve appropriate positioning of the button.

4β-Hydroxywithanolide E isolated from Physalis pruinosa calyx decreases inflammatory responses by inhibiting the NF-κB signaling in diabetic mouse adipose tissue. Int J Obes (Lond) 2014; 38:1432-9.

Abstract
BACKGROUND Chronic inflammation in adipose tissue together with obesity induces insulin resistance. Inhibitors of chronic inflammation in adipose tissue can be a potent candidate for the treatment of diabetes; however, only a few compounds have been discovered so far. The objective of this study was to find a novel inhibitor that can suppress the inflammatory response in adipose tissue and to elucidate the intracellular signaling mechanisms of the compound. METHODS To find the active compounds, we established an assay system to evaluate the inhibition of induced MCP-1 production in adipocyte/macrophage coculture in a plant extract library. The active compound was isolated by performing high-performance liquid chromatography (HPLC) and was determined as 4β-hydroxywithanolide E (4βHWE) by nuclear magnetic resonance (NMR) and mass spectroscopy (MS) spectral analyses. The effect of 4βHWE on inflammation in adipose tissue was assessed with adipocyte culture and db/db mice. RESULTS During the screening process, Physalis pruinosa calyx extract was found to inhibit production of MCP-1 in coculture strongly. 4βHWE belongs to the withanolide family of compounds, and it has the strongest MCP-1 production inhibitory effect and lowest toxicity than any other withanolides in coculture. Its anti-inflammatory effect was partially dependent on the attenuation of NF-κB signaling in adipocyte. Moreover, in vivo experiments showed that the oral administration of 4βHWE to db/db mice resulted in the inhibition of macrophage invasion and cytokine expression in adipose tissue after 2 weeks of treatment; improved the plasma adiponectin, non-esterified fatty acids and MCP-1 concentrations; and increased glucose tolerance after 3 to 4 weeks of treatment. CONCLUSIONS These results suggest that 4βHWE has anti-inflammatory effect via inhibition of NF-κB activation in adipocyte. Moreover, the attenuation of inflammation in adipocyte has an effect on the inhibition of macrophage accumulation in obese adipose tissue. Consequently, 4βHWE improves impaired glucose tolerance. Thus, 4βHWE is a useful natural anti-inflammatory compound to attenuate progression of diabetes and obesity.

Abstract
The influenza A virus is a causative agent of influenza, which infects human cells and uses host factors to accomplish viral genome replication as part of its life cycle. The nucleoprotein (NP) and PB2 of the influenza virus associate with importin α1 to gain access to the host nucleus through a ternary import complex. Killer cell-mediated cytotoxicity is the primary mechanism of eliminating the influenza virus. Here, we showed that lymphokine-activated killer cells participated in the elimination of the influenza virus. Granzyme (Gzm) K inhibition elevated viral replication in vitro and aggravated viral infection in vivo. We identified that importin α1 and its transport partner protein importin β are physiological substrates of GzmK. Proteolysis of these two substrates wrecked their association to generate the importin α1/β dimer and disrupted transportation of viral NP to the nucleus, leading to inhibition of influenza virus replication.
