The optimal cumulative cisplatin dose (CCD) during radiation therapy for locoregionally advanced nasopharyngeal carcinoma (LA-NPC) patients receiving induction chemotherapy (IC) plus CCRT remains controversial. This study aimed to explore the treatment efficiency of CCD for high-and low-risk patients with LA-NPC.

Data from 472 LA-NPC patients diagnosed from 2014 to 2018 and treated with IC plus CCRT were reviewed. After propensity score matching, the therapeutic effects of a CCD>200 and CCD≤200mg/m
were evaluated comparatively. Five factors selected by multivariate analysis were incorporated to develop a nomogram. Subgroup analysis was conducted to explore the role of different CCDs in nomogram-defined high- and low-risk groups. Additionally, acute toxicities were evaluated comparatively between the high- and low-CCD groups.

After matching, there was no difference between different CCD groups for all patients in terms of 3-year overall survival (OS), distant metastasis-free survival (DMFS), locoregional recurrence-free survival (LRRFS), or progression-free survival (PFS). A nomogram was built by integrating pretreatment EBV DNA, clinical stage, and post-IC EBV DNA, post-IC primary gross tumor and lymph node volumes obtained a C-index of 0.674. The high-risk group determined by the nomogram had poorer 3-year PFS, OS, DMFS, and LRRFS than the low-risk group. A total of CCD>200mg/m
increased the survival rates of 3-year PFS and DMFS (PFS 72.5% vs. 54.4%, p=0.012; DMFS 81.9% vs. 61.5%, p=0.014) in the high-risk group but not in the low-risk group. Moreover, the high CCD increased treatment-related acute toxicities.

A high CCD was associated with better 3-year PFS and DMFS rates than a low dose for high-risk patients but could not produce a survival benefit for low-risk patients.

The aim of this study was to estimate the efficacy and safety of bevacizumab combined with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR TKIs) in advanced non-small cell lung cancer (NSCLC) patients.

We searched randomized controlled trials (RCTs) on bevacizumab combined with EGFR TKIs in the NSCLC Cochrane Library, Web of Science, PubMed and Embase. The data were extracted and assessed according to the Cochrane Handbook. We calculated the hazard ratio (HR), risk ratio (RR), and confidence interval (CI), and accomplished this meta-analysis with Stata 14 software.

Of 1301 articles scanned, five articles were involved in this meta-analysis. We determined that compared with using EGFR TKIs alone, combination treatment significantly prolongs progression-free survival (PFS) (HR=0.61, 95% CI=0.52-0.70; p < 0.001), and increases the objective response rate (ORR) (RR=1.15, 95% CI 1.01-1.30, p=0.10). However, there was no significant difference in overall survival (OS) between the two groups (HR=0.95, 95% CI=0.78-1.11; p=<0.001) and combination treatment increases the risks of serious adverse events (SAEs) (RR=1.58, 95% CI 1.21-2.05, p=0.002).

Bevacizumab combined with EGFR-TKI significantly improves PFS and ORR in patients with advanced NSCLC, but there is no substantial difference in OS and increase the risks of serious adverse events.

As these diseases are difficult to diagnose clinically, biomarkers of underlying pathophysiology are playing an ever-increasing role in research, clinical trials, and in the clinical work-up of patients. Though cerebrospinal fluid (CSF) and positron emission tomography (PET)-based measures are available, their use is not widespread due to limitations, including high costs and perceived invasiveness. As a result of rapid advances in the development of ultra-sensitive assays, the levels of pathological brain- and AD-related proteins can now be measured in blood, with recent work showing promising results. Plasma P-tau appears to be the best candidate marker during symptomatic AD (i.e., prodromal AD and AD dementia) and preclinical AD when combined with Aβ42/Aβ40. Though not AD-specific, blood NfL appears promising for the detection of neurodegeneration and could potentially be used to detect the effects of disease-modifying therapies. This review provides an overview of the progress achieved thus far using AD blood-based biomarkers, highlighting key areas of application and unmet challenges.Nanotheranostic tailor-made carriers are potent platforms for the treatment of cancer that propound a number of advantages over conventional agents for photodynamic therapy (PDT). selleck Herein, four new heavy atom free amphiphilic glucose-BODIPY-fullerene dyads (14-17) endowed with carbohydrate units in the styryl units, which can also form nanomicelles (14-17NM) with Tween 80 for PDT are reported. Glucose-BODIPY-fullerene systems (14-17) and related nanomicelles (14-17NM) have been prepared to emcee efficient singlet oxygen generation upon light irradiation. In vitro anti-tumor effects of the compounds 14-17 and 14-17NM in the presence of light and in darkness have been investigated with K562 human chronic myelogenous leukemia suspension cells. Anti-tumor toxicity upon light irradiation was due to the formation of singlet oxygen and reactive oxygen species (ROS). This study may provide an accomplished example of efficient PDT applications based on nanovehicles fabricated with universal spin converter, fullerene, light harvesting unit, BODIPY dyes conjugated with targeting units to fight against cancer.
Despite reports of decreased bone mineral density in patients with systemic sclerosis (SSc) in international cohorts, the prevalence of osteoporosis in Australian SSc patients remains unknown. We report rates of dual-energy X-ray absorptiometry (DXA) scanning in an SSc cohort at a tertiary hospital specialized outpatient clinic and the prevalence and associations of osteoporosis in screened patients.

We performed retrospective chart review to determine if patients underwent DXA scanning between 2007 and 2018 and extracted lumbar spine and femoral neck T-scores, fracture history, and osteoporosis therapy.

Of 244 patients, 104 (42.6%) underwent DXA scanning and among patients in whom T-scores were available (n = 91), 30 (33.0%) had osteoporosis and 48 (52.7%) had osteopenia. Screened patients were more likely to have longer disease duration (19.9 vs 15.2 years, P = 0.002), calcinosis (50.5% vs 36.4%, P = 0.028), myositis (12.6% vs 0.7%, P < 0.001), synovitis (42.7% vs 28.6%, P = 0.022), ever used prednisolone (76.7% vs 47.1%, P < 0.001) or fractures (23.0% vs 0.0%, P < 0.001). Patients with osteoporosis more commonly had a history of nasogastric feeding, percutaneous endoscopic gastrostomy feeding or intravenous total parenteral nutrition (6.9% vs 0.0%, P = 0.038) and, unexpectedly, less commonly ever used prednisolone (58.6% vs 85.2%, P = 0.005) compared with patients with osteopenia or normal bone density.

We identified high rates of osteoporosis among screened Australian SSc patients. Further assessment in larger, prospective studies is needed to establish guidelines for formal osteoporosis screening in SSc patients.

Here we sequenced the genome of the Common Lumpfish (Cyclopterus lumpus Linnaeus), a species of increasing importance to aquaculture, and identified the SD region and master SD locus using a 70K SNP array and tissue-specific expression data. The chromosome-level assembly identified 25 diploid chromosomes with a total size of 572.89 Mb, a scaffold N50 of 23.86 Mb, and genome annotation predicted 21,480 protein-coding genes. Genome wide association analysis located a highly sex-associated region on chromosome 13, suggesting that anti-Müllerian hormone (AMH) is the putative SD factor. Linkage disequilibrium and heterozygosity across chromosome 13 support a proto-XX/XY system, with an absence of widespread chromosome divergence between sexes. We identified three copies of AMH in the Lumpfish primary and alternate haplotype assemblies localized in the SD region. link2 Comparison to sequences from other teleosts suggested a monophyletic relationship and conservation within the Cottioidei. One AMH copy showed similarity to AMH/AMHY in a related species and was also the only copy with expression in testis tissue, suggesting this copy may be the functional copy of AMH in Lumpfish. The two other copies arranged in tandem inverted duplication were highly similar, suggesting a recent duplication event. This study provides a resource for the study of early sex chromosome evolution and novel genomic resources that benefits Lumpfish conservation management and aquaculture.
The aim of this study was to evaluate and compare two different apheresis and changes in some immunological factors in donors.

The cross-sectional study was performed from January 2017 to September 2018. Fifty six male blood donors were randomly divided into two groups. CD4, CD8, and CD25 markers by flow cytometry, and TGFBeta by real-time polymerase chain reaction (RT-PCR) method were done before and 7 days after the apheresis procedure. Independent Sample t-test, Mann-Whitney U Test, Wilcoxon signed ranked test, and Fisher exact test were used.

WBC in MCS+ group after donation is significantly higher than before donation (P < 0.05) but no significant difference was seen between MCS+ and Trima groups in these two indicators. But in CD4, CD25, and TGFBeta, there was no significant difference between the two groups.

There was no significant difference on CD4, CD25, and TGFBeta gene 7 days after donation.

Brain stimulation is achieved through the application of electric currents using non-invasive as well as invasive techniques. link3 Recent technological advancements have evolved into the development of precise devices with capacity to produce well-controlled and effective brain stimulation. Currently, most used non-invasive techniques are repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS), whereas the most common invasive technique is deep brain stimulation (DBS). In last decade, application of these brain stimulation techniques has not only exploded but also expanded to wide variety of neurological disorders. Therefore, in the current review, we will provide an overview of the potential of both non-invasive (rTMS and tDCS) and invasive (DBS) brain stimulation techniques in the treatment of such brain diseases.
