The standard of care for first-line treatment of recurrent and/or metastatic squamous cell carcinoma of the head and neck (R/M SCCHN) in patients who cannot tolerate platinum-based regimens has not been clarified. We aimed to develop a new treatment regimen for patients with R/M SCCHN who are ineligible for platinum-based therapy, by evaluating the effects and safety of tegafur/gimeracil/oteracil (S-1) and cetuximab.

Platinum-ineligibility was defined as elderly (aged ≥ 75years), poor PS, comorbidity, platinum resistance and refusal to undergo platinum-based therapy. Patients received S-1 (80mg/m
/day for 14days followed by a seven-day break) and cetuximab (initial dose, 400mg/m
, followed by 250mg/m
weekly) until disease progression or unacceptable toxicity. The primary endpoint was overall response rate (ORR).

Between September 2014 and September 2018, we enrolled 23 patients. Among the 21 patients who were evaluable, 20 were male [median age, 69years (range 49-82)]. The ORR was 9 (43%) of 21 patients [95% confidence interval (CI) 22-66]. INCB39110 One and eight patients achieved complete response (CR) and partial response (PR), respectively. The median overall survival (OS) was 13.7months (95% CI 9.0-18.3) and progression-free survival (PFS) was 5.7months (95% CI 3.1-8.2). Grade 3/4 adverse events included acneiform rash and skin reactions (33%), hypomagnesemia (19%), hand-foot syndrome (14%), fatigue (14%), mucositis (10%), and anorexia (10%).

Combination treatment with S-1 and cetuximab was effective and tolerated well by patients with platinum-ineligible R/M SCCHN. Registered clinical trial number UMIN000015123.

In this article we argue that the conditions for being in error about the identity of taxonomic groups through their names have a history, and that the possibility of committing such errors is contingent on the regime of institutions and conventions governing taxonomy and nomenclature at any given point in time. More specifically, we claim that taxonomists today can be in error about the identity of taxonomic groups in a way that Carl Linnaeus (1707-1778), who is routinely cited as the "founder" of modern taxonomy and nomenclature, simply could not be. Starting from a remarkable recent study into Linnaeus's naming of Elephas maximus that led to the (putative) discovery of a (putative) nomenclatural error by him, we reconsider what it could mean to discover that Linnaeus misidentified a biological taxon in applying his taxon names. Through a further case study in Linnaean botany, we show that his practices of (re)applying names in taxonomic revisions reveal a take on determining "which taxon is which" that is strikingly different from that of contemporary taxonomists. Linnaeus, we argue, adopted a practice-based, hands-on concept of taxa as "nominal spaces" that could continue to represent the same taxon even if all its former members had been reallocated to other taxa.Although it was demonstrated that curcumin-mediated antimicrobial photodynamic therapy (aPDT) is effective for reducing the viability of microbial cells and the vitality of oral biofilms, the cytotoxicity of this therapeutic approach for host cells has not been yet elucidated. Hence, the aim of this study was to evaluate the cytotoxicity and apoptotic effects of curcumin-mediated aPDT on mouse fibroblasts. Cells were treated with 0.6 or 6 μmol.L-1 curcumin combined with 0.075 or 7.5 J.cm-2 LED at 455 nm. Cytotoxicity was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and crystal violet (CV) assays, while quantitative reverse transcriptase-PCR (qRT-PCR) was used to assess the expression of Bax, Bad, Bcl-2, VDAC-1, cytochrome C, and Fas-L genes for apoptosis. The differences between groups were detected by Kruskal-Wallis and post hoc Dunn's tests for MTT and CV assays and by ANOVA and post hoc Tukey test for qRT-PCR (P less then 0.05). The effect of 0.6 μmol.L-1 curcumin plus 0.075 J.cm-2 LED (minimum parameter) did not differ statistically from control group; however, the combination of 0.6 μmol.L-1 curcumin plus 7.5 J.cm-2 LED reduced viable cells in 34%, while the combinations of 6 μmol.L-1 curcumin plus 0.075 and 7.5 J.cm-2 LED reduced viable cells in 47% and 99%, respectively. aPDT increased significantly the relative expression of Bax/Bcl-2, cytochrome C, VDAC-1, and Fas-L genes, without influence on the ratio Bad/Bcl-2. Therefore, curcumin-mediated aPDT activated Bcl-2 apoptosis signaling pathways in mouse fibroblasts regarding present conditions, reducing the viability of cells with the increase of curcumin concentrations and light energies.
The moderate-penetrance germline mutations ATM, CHEK2, and PALB2 are implicated in an increased risk of the development of breast cancer. Whether these mutations provide clinical utility to guide treatment strategies and prognosis remains unknown.

A retrospective case-control study from a tertiary institution compared patients with stage 0-III breast cancer, and positive for ATM, CHEK2, or PALB2 mutations, with a matched cohort selected by randomization and negative for mutations. Data acquisition included demographics, histopathologic, treatment, and clinical outcome variables.

A total of 145 patients with breast cancer (144 female and 1 male) were analyzed-74 mutation-positive patients (24 ATM, 26 CHEK2, 24 PALB2) and 71 mutation-negative patients. Mutation-positive patients compared with mutation-negative patients had increased family history of breast cancer (79.7 vs. link2 52.9%, p < 0.001) and tumor size > 2.0cm (63.1% vs. 42.3%, p = 0.015). Patients with prior knowledge of mutational status were otal mastectomy. Further studies are needed to confirm these findings.Ethnic-racial identity (ERI) formation is a key developmental competency that contributes to adolescents' sense of self and psychosocial adjustment. A randomized controlled trial (RCT) has demonstrated the efficacy of a universal school-based health promotion intervention program to positively influence adolescents' ERI exploration and ERI resolution, compared to an attention control curriculum that was delivered by the same facilitators, had equivalent contact hours, and focused on post-secondary career and educational options. The current study extended prior tests of the RCT to better understand (a) how intervention-based ERI changes unfolded over two phases-temporally proximal pre- to post-test effects and long-term post-test effects across a 1-year follow-up period, and (b) identify for whom the intervention was more effective by testing theorized contextual moderators-baseline family ethnic socialization practices and youth ethnic-racial background (i.e., White majority vs. ethnic-racial minority). Bilinear spline growth models were used to examine longitudinal ERI trajectories in intervention and control groups across four survey assessments (baseline, 12 weeks, 18 weeks, 67 weeks; N = 215; Mage = 15.02; 49.1% female; 62.6% ethnic-racial minority). link3 In support of an additive effect for the role of families in school-based interventions, post-test ERI exploration significantly increased (relative to the control group) to a greater extent for youth with higher (compared to lower) baseline levels of family ethnic socialization. ERI resolution significantly increased from pre- to post-test for ethnic-racial minority youth and also increased across the 1-year follow-up period for White youth in the intervention. These results highlight family ethnic socialization as a developmental asset for school-based ERI interventions and demonstrate differential pathways by which such interventions support ERI development for ethnic-racial minority and majority adolescents.A micro-electromechanical system (MEMS) scanning mirror accelerates the raster scanning of optical-resolution photoacoustic microscopy (OR-PAM). However, the nonlinear tilt angular-voltage characteristic of a MEMS mirror introduces distortion into the maximum back-projection image. Moreover, the size of the airy disk, ultrasonic sensor properties, and thermal effects decrease the resolution. Thus, in this study, we proposed a spatial weight matrix (SWM) with a dimensionality reduction for image reconstruction. The three-layer SWM contains the invariable information of the system, which includes a spatial dependent distortion correction and 3D deconvolution. We employed an ordinal-valued Markov random field and the Harris Stephen algorithm, as well as a modified delay-and-sum method during a time reversal. The results from the experiments and a quantitative analysis demonstrate that images can be effectively reconstructed using an SWM; this is also true for severely distorted images. The index of the mutual information between the reference images and registered images was 70.33 times higher than the initial index, on average. Moreover, the peak signal-to-noise ratio was increased by 17.08% after 3D deconvolution. This accomplishment offers a practical approach to image reconstruction and a promising method to achieve a real-time distortion correction for MEMS-based OR-PAM.
Microsporidia infection was originally described as an immunocompromised associated pathogen. Limitations to correct microscopic diagnosis of microsporidia include size of the organism presenting a challenge even to a highly competent laboratory expert.

The present study aimed to detect microsporidia infection among leukemic children. The performance of modified trichrome stain and PCR in the diagnosis of microsporidia was evaluated with further speciation.

Stool samples of 100 leukemic children on chemotherapy were examined microscopically for microsporidia. DNA was extracted from all samples. Amplification was performed by conventional and nested PCR. Sequencing of amplified products was performed on unspeciated samples.

Microsporidia were detected in 23% of the children by MTS and 29% by PCR. The 29 positive samples were subjected to PCR for speciation. Enterocytozoon bieneusi was found to predominate in 20 cases, Encephalitozoon intestinalis in three cases, two cases had co-infection, and the remaining four samples were not amplified with either E. bieneusi or E. intestinalis specific primers. By DNA sequencing of the unspeciated samples, three samples shared high homology with Encephalitozoon hellem and one sample with Encephalitozoon cuniculi. Referring to PCR as a gold standard, MTS exhibited 72.4% sensitivity and 97.2% specificity with 90% accuracy. Among a number of studied variables, diarrhea and colic were significantly associated with microsporidia infection when diagnosed by either technique.

The use of sensitive and discriminative molecular tools will contribute to determining the true prevalence of microsporidiosis and possibly their potential transmission source depending on species identification.
