Abstract
Oxidative stress (OS) and disruption of proteostasis caused by aggregated proteins are the primary causes of cell death in various diseases. Selenopeptides have shown the potential to control OS and alleviate inflammatory damage, suggesting promising therapeutic applications. However, their potential function in inhibiting proteotoxicity is not yet fully understood. To address this gap in knowledge, this study aimed to investigate the effects and underlying mechanisms of the selenopeptide VPRKL(Se)M on amyloid β protein (Aβ) toxicity in transgenic Caenorhabditis elegans. The results revealed that supplementation with VPRKL(Se)M can alleviate Aβ-induced toxic effects in the transgenic C. elegans model. Moreover, the addition of VPRKL(Se)M inhibited the Aβ aggregates formation, reduced the reactive oxygen species (ROS) levels, and ameliorated the overall proteostasis. Importantly, we found that the inhibitory effects of VPRKL(Se)M on Aβ toxicity and activation of the unfolded protein are dependent on skinhead-1 (SKN-1). These findings suggested that VPRKL(Se)M is a potential bioactive agent for modulating SKN-1, which subsequently improves proteostasis and reduces OS. Collectively, the findings from the current study suggests VPRKL(Se)M may play a critical role in preventing protein disorder and related diseases.

Abstract
This study aimed to compare the nutritive value and obesity prevention of ordinary Cordyceps militaris (CM) and selenium-enriched CM (SeCM). The results indicated that Se enrichment significantly increased the total carbohydrate and soluble dietary fiber content, while the protein and insoluble dietary fiber content decreased. Although the fat content was not affected, the medium and long-chain fatty acids content significantly changed. Moreover, Se enrichment significantly elevated the secondary metabolites belonging to terpenoids and alkaloids, which are linked with the enhanced biosynthesis of secondary metabolites. Both CM and SeCM reduced body weight, adipose accumulation, impaired glucose tolerance, and lipid levels in high-fat diet (HFD)-fed mice, and there was no significant difference between them. Network pharmacological analysis revealed that dietary CM and SeCM prevented HFD-induced obesity and associated metabolic diseases with multi-ingredients acting on multi-targets. Overall, Se enrichment improved the nutritive value of CM without altering its role in preventing obesity.

Abstract
PURPOSE/OBJECTIVE(S) The outcomes of upfront or relapse radiation therapy (RT) for the Children's Oncology Group ACNS0334 protocol based on molecular diagnosis were assessed. Therapy included maximal safe surgery, high-dose chemotherapy with stem cell rescue, randomization for inclusion of high dose methotrexate (MTX) and optional RT. MATERIALS/METHODS There were 24 patients that received RT on COG ACNS0334 of 77 evaluable patients with a diagnosis of either high-risk medulloblastoma (MB) or supratentorial primitive neuroectodermal tumor (SPNET). RT was a recommendation (M0: Focal, M+: CSI 18 Gy) given young patient age <36 months at enrollment. Seven RT patients were excluded for ineligible pathology (1 ATRT, 1 HGG) or insufficient tissue. The aim of this report is to review outcomes of 17 patients on ACNS0334 receiving RT (8 Upfront, 9 at relapse) with a molecular diagnosis that included MB, Pineoblastoma (PB), or Embryonal tumor with multilayered rosettes (ETMR). RESULTS In the MB group, there were 9 patients irradiated with MB (Group 3 = 8, SHH = 1). 5-year OS for MB Group 3 receiving RT (median primary dose 54 Gy) was 62.5% with no difference observed comparing 6 patients treated with upfront RT versus 2 treated at relapse (p = 0.27). All upfront RT for MB Group 3 had initial partial response (PR) to 0334 chemotherapy. RT delivery for upfront RT MB Group 3 included craniospinal radiation (CSI) in 5 patients and 1 patient who received focal RT to the primary (50 Gy) and metastatic site (44 Gy). Eighty percent of CSI for upfront RT in Group 3 was 18 Gy or 23.4 Gy. Relapse RT for MB Group 3 (2 patients) utilized full dose CSI (36 Gy, 39.6 Gy) and both patients are survivors with 5+ years follow-up. CSI dose for Group 3 MB was higher for relapse RT (mean 37.8 Gy) as compared to upfront RT (mean 19.8 Gy, p = 0.013). Use of MTX was 50% in both upfront RT and relapse RT Group 3 MB cohorts. One patient with MB SHH (classic histology) underwent upfront focal RT (54 Gy) after initial PR to systemic therapy (without MTX) and is surviving 5+ years. PB: Of 4 PB patients (median primary dose 48.8 Gy) 1 had RT upfront (CSI 18 Gy) and 3 had RT at relapse (1 patient received CSI, 21 Gy). All patients with PB expired within 2 years. MTX was given in 75% (including 1 upfront RT PB). Two of 3 patients treated at relapse had prior complete response (CR). ETMR: All 4 patients (median primary dose 54 Gy) with ETMR were treated at relapse, with CSI given in 1 patient (23.4 Gy). All patients with ETMR expired within 2 years, and 2 (50%) had received MTX. Two patients (50%) had initial CR. CONCLUSION The RT cohort for Group 3 MB on ACNS0334 exhibited long-term survival both for both upfront and relapse RT, however relapsed Group 3 MB received higher dose CSI. RT upfront for MB, including one surviving MB SHH patient receiving focal RT, was solely given for incomplete initial chemotherapy response. There were no survivors for either PB or ETMR when the majority (88%) were treated at relapse.

Abstract
Selenopeptides are promising candidates for intervening in neuroinflammation; however, the key role of selenium (Se) in selenopeptides remains poorly understood. To address this gap, we compared the neuroprotective effects of selenopeptide Val-Pro-Arg-Lys-Leu-SeMet (namely, Se-P1) and its native peptide Val-Pro-Arg-Lys-Leu-Met (namely, P1). Our results demonstrate that Se-P1 treatment exhibits superior antioxidant and antineuroinflammatory effects in PC12 cells and lipopolysaccharide (LPS)-injured mice compared to P1. Moreover, the administration of Se-P1 and P1 resulted in a shift in the gut microbiota composition. Notably, during LPS-induced injury, Se-P1 treatment demonstrated greater stability in maintaining gut microbiota composition compared to P1 treatment. Specifically, Se-P1 may have a positive impact on gut microbiota dysbiosis by modulating inflammatory-related bacteria such as enhancing Lactobacillus abundance while reducing that of Lachnospiraceae_NK4A136_group. Furthermore, the alteration of metabolites induced by Se-P1 treatment exhibited a significant correlation with gut microbiota, subsequently modulating the inflammatory-related metabolic pathways including histidine metabolism, lysine degradation, and purine metabolism. These findings suggest that organic Se contributes to the bioactivities of Se-P1 in mitigating neuroinflammation in LPS-injured mice compared to P1. These findings hold significant value for the development of potential preventive or therapeutic strategies against neurodegenerative diseases and introduce novel concepts in selenopeptide nutrition and supplementation recommendations.

Abstract
Oxidative stress (OS) is created by an imbalance between reactive oxygen species and antioxidant levels. OS promotes inflammation and is associated with many diseases, such as neurodegenerative disorders, diabetes, and cardiovascular disease. Nrf2 and NF-κB are critical in the cellular defence against OS and the regulators of inflammatory responses, respectively. Recent studies revealed that the Nrf2 signalling pathway interacts with the NF-κB signalling pathway in OS. More importantly, many natural compounds have long been recognized to ameliorate OS and inflammation via the Nrf2 and/or NF-κB signalling pathway. Thus, we briefly overview the potential crosstalk between Nrf2 and NF-κB and the upstream regulators of Nrf2 and review the literature on the antioxidant and anti-inflammatory effects of dietary phytochemicals (DPs) that can activate these defence systems. The aim is to provide evidence for the development of DPs into functional food for the regulation of the Nrf2/NF-κB signalling pathway by upstream regulators of Nrf2.

Abstract
Improved gut microbes and nutritious metabolites have been considered as the mediators of health benefits from indigestible polysaccharides, but their role in the anti-obesity effect of polysaccharides from Cordyceps militaris (CMP) remains elusive. This study aims to explore the potential mediators of the anti-obesity effects of CMP in high-fat diet (HFD)-fed mice using 16S rRNA sequencing and untargeted metabolomics analysis. The results showed that CMP supplementation in HFD-fed mice reduced body weight, fat accumulation, pro-inflammatory cytokine levels, and impaired glucose tolerance as well as gut barrier. Moreover, the CMP reversed the HFD-induced gut microbiota dysbiosis, as indicated by the elevated population of Alloprevotella, Parabacteroides, Butyricimonas, and Alistipes; and decreased population of Negativebacillus, in addition to altered levels of metabolites, such as brassicasterol and 4'-O-methylkanzonol W. Notably, CMP prevented obesity in association with the altered gut microbes and metabolites. These findings suggest that CMP may serve as a potential prebiotic agent to modulate specific gut microbes and related metabolites, which play a critical role in its preventing obesity-related diseases.

Abstract
BackgroundOrelabrutinib is an oral, highly-selective, irreversible inhibitor of Bruton’s tyrosine kinase (BTK). Orelabrutinib has been approved for the treatment of B cell malignancies in China. Two distinct lupus animal models showed significant efficacy of orelabrutinib in reducing disease activity, which supported the clinical development of orelabrutinib in Systemic Lupus Erythematosus (SLE).ObjectivesThis phase Ib/IIa, randomized, double-blind, placebo-controlled, dose-finding study aimed to evaluate the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD), preliminary efficacy and biomarkers of orelabrutinib in patients with mild to moderate SLE who received standard of care (SoC) therapy.MethodsPatients diagnosed with SLE by the ACR classification criteria for ≥ 6 months, who had a SLEDAI-2K score ≥5 at screening, and were autoantibody-positive, were randomized 1:1:1:1 to receive oral orelabrutinib at 50mg, 80mg, 100mg or placebo once daily for 12 weeks, respectively.ResultsThis study randomized 60 patients with 55 patients who completed 12-week treatment. Age at baseline was 33.7±9.8 years and 96.7% were female. Baseline disease characteristics were generally balanced across treatment groups. Adverse events (AEs) were reported in 80%, 93.3% and 100% of orelabrutinib treated patients at doses of 50mg, 80mg and 100mg QD respectively versus 85.5% in placebo group. AEs were mostly mild or moderate. Treatment-related SAEs were reported in 3 patients treated with orelabrutinib, only 1 of which was grade 3. No deaths were reported. The plasma exposure of orelabrutinib (AUC and Cmax) was proportionally increased with doses. Nearly complete BTK occupancy was achieved at all dose levels, and the occupancy lasted for 24 hours without any decrease compared to that at 4 hour post-dosing. In all evaluable patients, the SLE Response Index (SRI)-4 response rates at week 12 were 50.0%, 61.5% and 64.3% in patients treated with orelabrutinib at 50mg (n=14), 80mg (n=13) and 100mg (n=14) respectively, compared with 35.7% in patients treated with placebo (n=14), which indicated the trend of dose-dependent improvement. Among the subgroup of patients with SLEDAI-2K≥8 at screening, SRI-4 response occurred in 70%, 70% and 66.7% of patients treated with orelabrutinib at 50mg (n=10), 80mg (n=10) and 100mg (n=9), respectively, compared with 30% who received placebo (n=10). Trends of reduced proteinuria, anti-dsDNA and IgG, total B cells and increased complements C4 were also observed following orelabrutinib treatment.ConclusionOrelabrutinib was generally safe and well tolerated in patients with SLE. Preliminary results also suggested encouraging efficacy which supports further development of orelabrutinib in larger and longer trials for SLE.Table 1.Efficacy results at week 12.All Evaluable PatientsPlaceboOrelabrutinibOrelabrutinibOrelabrutinib50 mg80 mg100 mgN=5514141314SRI-4 response, n (%)5 (35.7%)7 (50.0%)8 (61.5%)9 (64.3%)Treatment difference vs. PBO (%)14.3%25.8%28.6%SLEDAI-2K≥8, N=391010109SRI-4 response, n (%)3 (30.0%)7 (70.0%)7 (70.0%)6 (66.7%)Treatment difference vs. PBO (%)40.0%40.0%36.7%Note: All evaluable patients at week 12 efficacy data were included in the efficacy analysis.Figure 1.SRI-4 response rates at week 12.Disclosure of InterestsRu Li: None declared, Xiaoxia Zhu: None declared, Shengyun Liu: None declared, Xiao Zhang: None declared, Changhao Xie: None declared, Zili Fu: None declared, Anbin Huang: None declared, Lingyun Sun: None declared, Dongzhou Liu: None declared, Jinxia Zhao: None declared, Lin Wu: None declared, Zhoushuai Qin Employee of: InnoCare Pharma Limited., Sichen Li Employee of: InnoCare pharma Limited., Yaorong Liu Employee of: InnoCare pharma Limited., Zhanguo Li: None declared

Abstract
The widely used neonicotinoid insecticide imidacloprid has emerged as a significant risk to surface waters and the diverse aquatic and terrestrial fauna these ecosystems support. While herbicides have been the focus of research on pesticides in Australia's Great Barrier Reef catchment area, imidacloprid has been monitored in catchments across the region since 2009. This study assessed the spatial and temporal dynamics of imidacloprid in 14 waterways in Queensland, Australia over seven years in relation to land use and concentration trends. Imidacloprid could be quantified (i.e., concentrations were greater than the limit of reporting) in approximately 54% of all samples, but within individual waterways imidacloprid was quantified in 0 to 99.7% of samples. The percent of each catchment used to grow bananas, sugar cane and urban explained approximately 45% of the variation in imidacloprid concentrations and waterway discharge accounted for another 18%. In six waterways there were significant increases in imidacloprid concentrations and the frequency and magnitude of exceedances of aquatic ecosystem protection guidelines over time. Overall, the risk posed by imidacloprid was low with 74% of samples protecting at least 99% of species but it was estimated that upto 42% of aquatic species would experience harmful chronic effects. Potential explanations of the changes in imidacloprid were examined. Not surprisingly, the only plausible explanation of the increases was increased use of imidacloprid. While field-based measurement of the effects of imidacloprid are limited in the Great Barrier Reef Catchment Area (GBRCA) the risk assessment indicates that biological harm to aquatic organisms is highly likely. Action to reduce imidacloprid concentrations in the GBRCA waterways is urgently required to reverse the current trends and mitigate environmental impacts.

Abstract
Polysaccharide from Agrocybe cylindracea (ACP) has been demonstrated with various health benefits, but its anti-obesity effect and underlying mechanisms remain poorly understood. This study aimed to investigate the beneficial effects of ACP in high-fat diet (HFD)-induced obese mice by targeting gut microbiota and metabolites. 9-week ACP supplementation in HFD-fed mice reduced body weight, adipose accumulation, impaired insulin resistance, lipid levels, and liver injuries, which were negatively correlated to the pro-inflammatory factors, particularly tumor necrosis factor-alpha (TNF-α) and interleukin- 6 (IL-6). Moreover, ACP not only restored HFD-induced gut disorder, as indicated by the depletion of Desulfovibrio and Oscillibacter and the enrichment of the Bacteroides, Parabacteroides, Butyricimonas, and Dubosiella, but also positively regulated gut metabolites such as solavetivone and N-acetylneuraminic acid. Spearman's correlation analysis revealed that the ACP-altered microbes and metabolites were highly correlated with inflammation-related indexes. Notably, ACP greatly lowered the obesity-related TNF-α- and IL-6-levels partially by reducing Desulfovibrio and increasing Parabacteroides abundances, together with the associated decrease of solavetivone level. These findings suggest that ACP may be used as a prebiotic agent to prevent diet-induced obesity, and target-specific microbiota and metabolites may have unique therapeutic promise for inflammation-related diseases.

Abstract
PURPOSE To investigate the impact of restrictions on access to long acting oxycodone on prescription opioid use and opioid-related harms. METHODS Administrative health data from Ontario, Canada was used to measure differences in opioids dispensed and ED visits for opioid-related overdose, poisoning or substance use following provincial restrictions on access to publicly insured OxyContin (February 29, 2012) and OxyNeo (February 28, 2013). This study focused on the cohort of provincial drug insurance eligible people (people 65+ and select low-income populations) who were dispensed oxycodone prior to the restrictions. Difference-in-differences models with a propensity score matched comparison group of people who were dispensed non-oxycodone opioids were used to estimate the main effects. RESULTS In the six months following the delisting of OxyContin, MMEs per person per week for all opioids fell by an average of 7.5% in people dispensed oxycodone relative to the comparison group, and an average of 13.8% in chronic recipients of oxycodone. In the six months following the restrictions on OxyNeo, MMEs per person per week fell by an average of 3.1% in all people dispensed oxycodone, and 25.2% in chronic oxycodone recipients. The decline in oxycodone dispensing amongst chronic oxycodone recipients corresponded with an increase in dispensing of other opioid formulations, particularly hydromorphone and fentanyl. No important differences were observed for ED visits related to opioid poisoning, overdose, or substance use disorder. CONCLUSIONS Province-wide restrictions on access to long acting oxycodone had an impact on quantities of all opioids dispensed to chronic recipients of oxycodone, but small impacts on the full population of people dispensed oxycodone; the decline in use was partially offset by increases in use of other publicly-funded opioid formulations. This study suggests that policies limiting access to specific prescription opioids led to overall reductions in publicly-funded prescription opioid use, particularly in chronic oxycodone recipients, without immediate evidence of changes in opioid-related ED visits.

Abstract
Increasing attention focuses on the relationship between neuroinflammation and Alzheimer's disease (AD). The reports on the microbiota-gut-brain axis reveal that the regulation by gut microbiota is an effective way to intervene in neuroinflammation-related AD. In this study, two novel selenium peptides (Se-Ps), VPRKL(Se)M (Se-P1) and RYNA(Se)MNDYT (Se-P2), with neuroprotection effects were obtained from Se-enriched Cordyceps militaris. Se-P1 and Se-P2 pre-protection led to a 30 and 33% increase in the PC-12 cell viability compared to the damage group, respectively. Moreover, Se-Ps exhibited a significant pre-protection against LPS-induced inflammatory and oxidative stress in the colon and brain by inhibiting the production of pro-inflammatory mediators (p < 0.05) and malondialdehyde, as well as promoting anti-inflammatory cytokine level and antioxidant enzyme activity (p < 0.05), which may alleviate the cognitive impairment in LPS-injured mice (p < 0.05). Se-Ps not only repaired the intestinal mucosa damage of LPS-injured mice but also had a positive effect on gut microbiota dysbacteriosis by increasing the abundance of Lactobacillus and Alistipes and decreasing the abundance of Akkermansia and Bacteroides. Collectively, the antioxidant, anti-inflammatory, and regulating properties on gut microflora of Se-Ps contribute to their neuroprotection, supporting that Se-Ps could be a promising dietary supplement in the prevention and/or treatment of AD.

Abstract
SCOPE Whole-food-based strategies to prevent metabolic diseases are growing interests. Agrocybe cylindracea (AC) is a major edible mushroom with high values of nutrition, but little is known about its health benefits as a portion of whole food. METHODS AND RESULTS Diet-induced obese, C57BL/6J mice were fed an HFD with or without AC (3% or 5%, w/w in the diet) for 9 weeks. The results showed that dietary AC reduced body weight, adipose accumulation, impairment of glucose tolerance, lipid levels, and liver injury in HFD-fed mice. Moreover, AC not only prevented HFD-induced gut disorder, as indicated by the enriched probiotic Bifidobacterium and reduced endotoxin-bearing Proteobacteria, but also improved the endotoxin (LPS) level and gut tissue structure. Fecal metabolites such as harmine and harmanine were also remarkably altered by AC. Spearman's correlation analysis revealed that the AC-altered microbes and metabolites were strongly correlated with obesity-related indexes. CONCLUSION These findings suggest that dietary AC prevents HFD-induced obesity and its complications in association with modulating gut microbiota and associated fecal metabolites.

Abstract
A common clinical problem encountered by colorectal surgeons is the secondary tumors of the ovary (STO), particularly in young female patients. Most STO are from the digestive tract, and the known possible metastatic mechanisms include lymphatic, hematogenous, and intraperitoneal spreading. The molecular and histopathological characteristics of STO from different sites are diverse. It is particularly important to correctly identify the origin and feature of STO, which should be clarified by combining medical history, histopathology, immunohistochemistry, molecular biology, imaging and other means. The prognosis of patients with STO is poor in general. Comprehensive therapies based on surgical resection can benefit some patients. There is no specific treatment for STO at present, but not giving up easily on these patients is the right choice that every surgeon should understand.

Abstract
Abstract
Introduction
Myocardial infarction (MI) accelerates atherosclerosis and for years greatly increases the risk of recurrent cardiovascular events, such as stroke and MI. B cell-derived autoantibodies produced in response to MI also persist for years.
Purpose
We investigated the role of B cells in adaptive immune responses to MI.
Methods
We used an apolipoprotein-E-deficient (ApoE−/−) mouse model of MI-accelerated atherosclerosis to assess the importance of B cells using loss and gain of function approaches. In loss of function experiment, after inducing an MI we depleted B cells using an anti-CD20 antibody. Gain of function experiments involve transfers of purified MI-B cells from different donor mice, isolated one week after MI, into atherosclerotic ApoE−/− mice.
Results
Depletion of B cells in MI mice prevented immunoglobulin G accumulation in plaques and MI-induced acceleration of atherosclerosis. Adoptive transfer of wildtype MI-B cells into atherosclerotic ApoE−/− mice greatly increased IgG accumulation in plaque and accelerated atherosclerosis in recipient mice. Cytokines that promote humoral immunity were also greatly increased in B cells activated by MI. These cells formed germinal centres within the spleen where they differentiated into antibody-producing plasma cells. Transfer of MI-B cells deficient in Blimp-1, the transcriptional repressor that drives their terminal differentiation to antibody-producing plasma cells failed to accelerate atherosclerosis in recipient mice. Alarmins released from infarcted heart were responsible for activation of B cells via toll-like receptors; transfer of MI-B cells deficient in MyD88, the canonical adaptor protein for inflammatory signaling downstream of toll-like receptors, prevented acceleration of atherosclerosis in recipient mice.
Conclusion
Our data implicate early B cell activation and autoantibodies as a central cause for accelerated atherosclerosis post MI and identifies novel therapeutic strategies towards preventing recurrent cardiovascular events such as MI and stroke.

Abstract
PURPOSE The goal of this study is to determine a link between benign essential blepharospasm and Sjogren's syndrome by analyzing the presence of extractable nuclear antigens in this population. METHODS Seventy-two patients with benign essential blepharospasm (BEB) were included in this study. We eliminated patients with hemifacial spasm or blepharospasm secondary to corneal pathology. We collected the values of the Schirmer I test and the results of the anti-SSA and anti-SSB antibodies. RESULTS Our study included 72 patients (144 eyes) whose 62 women (86.1%). Mean age was 74.3 years±10.73. Average Schirmer I test was 3.14mm±4.00mm. Five women (8% of this female population) had positive anti-SSA and SSB antibodies. Their mean age was 65.66 years±13.24 whereas the negative antibody patients had an average age of 75.42±9.27. There was no significant difference between their Schimer I test and the Schirmer I of negative antibody population. CONCLUSION This study illustrates the possible association between the presence of Sjögren's syndrome and the occurrence of a BEB justifying the search for anti-SSA and anti SSB in blepharospasm patients.

Abstract
PURPOSE To study whether there is an association between benign essential blepharospasm and Sjögren's syndrome by analyzing the presence of antibodies to extractable nuclear antigens in this population. METHODS Seventy-two patients with benign essential blepharospasm (BEB) were included in this study. We excluded patients with hemifacial spasm or blepharospasm secondary to known corneal pathology. We recorded results of Schirmer I testing as well as levels of anti-SSA/Ro and anti-SSB/La antibodies. RESULTS Our study included 72 patients (144 eyes), of which 62 (86.1%) were women. The mean age was 74.3±10.73 years. The mean Schirmer I test result was 3.14±4.00mm. Five women (8% of this female population) were found to have positive anti-SSA/Ro and anti-SSB/La antibodies. Their mean age was 65.66±13.24 years, while the mean age of the antibody-negative patients was 75.42±9.27 years. There was no statistically significant difference between the Schirmer I tests of the antibody positive and negative patients. CONCLUSION This study demonstrates a possible association between Sjögren's syndrome and benign essential blepharospasm, justifying anti-SSA/Ro and anti-SSB/La testing in these patients.

Abstract
Abstract
Fifteen laboratories completed a collaborative study comparing the efficacy of a latex agglutination kit (Aureus Test) with that of AOAC Official Method 987.09 (coagulase test for identification of Staphylococcus aureus). Each laboratory analyzed 240 strains of bacteria, including 160 isolates of S. aureus and 80 isolates of other bacteria. Upon receipt of cultures, collaborators subcultured each isolate on both tryptic soy agar (TSA) and Baird-Parker agar medium (BPA) to determine whether the growth medium has any effect on either method. For cultures grown on TSA, the latex test had sensitivity and specificity rates of 99.2 and 97.1 %, respectively, whereas the coagulase test had respective rates of 98.4 and 92.5%. For cultures able to grow on BPA, the latex test had sensitivity and specificity rates of 99.2 and 96.6%, respectively, while the coagulase test had respective rates of 98.3 and 91.3%. By using the McNemar pairwise comparison test of the 2 methods, the falsepositive and false-negative rates of the latex test were significantly lower (p < 0.01) than those of the coagulase test for strains grown either on TSA or BPA. The latex agglutination test for identification of S. aureus isolated from foods has been adopted by AOAC INTERNATIONAL.

Abstract
Objective:To investigate the expression of BRCA1 associated protein(BRAP) and its correlations with clinicopathological features and prognosis of patients with laryngeal squamous cell carcinoma(LSCC). Method:The protein expression of BRAP in LSCC tissues and normal laryngeal tissues were assessed by immunohistochemistry and Western blot, and their correlations with clinicopathological features and prognosis were statistically analyzed. Result:The expression of BRAP in LSCC was significantly higher than that in normal laryngeal tissues(P<0.05). BRAP expression was significantly correlated with the TNM stage and lymph node metastasis(P<0.05). Kaplan-Meier survival analysis showed that LSCC patients with high BRAP expression had worse overall survival than those with low BRAP expression(P<0.01). Multivariate Cox proportional-hazards analysis showed that the high expression of BRAP protein was an important poor prognostic indicator of the patients. Conclusion:BRAP is related with the development of LSCC, and it may be used as an important prognostic biomarker for LSCC patients.

Abstract
BACKGROUND Early identification of vasospasm prior to symptom onset would allow prevention of delayed cerebral ischemia (DCI) in aneurysmal subarachnoid hemorrhage (aSAH). Dynamic cerebral autoregulation (DCA) is a noninvasive means of assessing cerebral blood flow regulation by determining independence of low-frequency temporal oscillations of systemic blood pressure (BP) and cerebral blood flow velocities (CBFV). METHODS Eight SAH patients underwent prospectively a median of 7 DCA assessments consisting of continuous measurements of BCFV and BP. Transfer function analysis was applied to calculate average phase shift (PS) in low (0.07-0.2 Hz) frequency range for each hemisphere as continuous measure of DCA. Lower PS indicated poorer regulatory response. DCI was defined as a 2-point decrease in Glasgow Coma Score and/or infarction on CT. RESULTS Three subjects developed symptomatic vasospasm with median time-to-DCI of 9 days. DCI was significantly associated with lower PS over the entire recording period (Wald = 4.28; p = 0.039). Additionally, there was a significant change in PS over different recording periods after adjusting for DCI (Wald = 15.66; p = 0.001); particularly, a significantly lower mean PS day 3-5 after bleed (14.22 vs 27.51; p = 0.05). CONCLUSIONS DCA might be useful for early detection of symptomatic vasospasm. A larger cohort study of SAH patients is currently underway.
