Abstract
Gliomas are currently classified through integration of histology and mutation information, with new developments in DNA methylation classification. However, discrepancies exist amongst the major classification methods. This study sought to compare transcriptome-based classification to the established methods. RNAseq and microarray data were obtained for 1032 gliomas from the TCGA and 395 gliomas from REMBRANDT. Data were analyzed using unsupervised and supervised learning and other statistical methods. Global transcriptomic profiles defined four transcriptomic glioma subgroups with 91.4% concordance with the WHO-defined mutation subtypes. Using these subgroups, 168 genes were selected for the development of 1000 linear support vector classifiers (LSVC). Based on plurality voting of 1000 LSVC, the final ensemble classifier confidently classified all but 17 TCGA gliomas to one of the four transcriptomic profile (TP) groups. The classifier was validated using a gene expression microarray dataset. TP1 cases include IDHwt, glioblastoma high immune infiltration and cellular proliferation and poor survival prognosis. TP2a is characterized as IDHmut-codel, oligodendrogliomas with high tumor purity. TP2b tissue is mostly composed of neurons and few infiltrating malignant cells. TP3 exhibit increased NOTCH signaling, are astrocytoma and IDHmut-non-codel. TP groups are highly concordant with both WHO integrated histology and mutation classification as well as methylation-based classification of gliomas. Transcriptomic profiling provides a robust and objective method to classify gliomas with high agreement to the current WHO guidelines and may provide additional survival prediction to the current methods.

Abstract
This study examined the relationship between dyadic adjustment and sexual satisfaction, in Portuguese women diagnosed with human papillomavirus (HPV), using a 1-year longitudinal design. Women were assessed at the beginning of the study (N = 209), six months after (N = 178) and twelve months later (N = 105). A better dyadic adjustment predicted more sexual satisfaction but the inverse was not observed. Younger women (< 40 years) showed greater difficulties in dyadic adjustment, while older women (> 40 years) reported lower sexual satisfaction. Findings highlight the importance of intervening with couples, using different intervention programs according to women's age.

Abstract
OBJECTIVE Determine the utility of a clinical calculator to predict the benefit of chemotherapy in stage IA uterine papillary serous cancer (UPSC). PATIENTS AND METHODS Data were collected from NCDB from years 2010-2014. Based on demographic and surgical characteristics, a clinical score was developed using the random survival forest machine learning algorithm. RESULTS Of 1,751 patients with stage IA UPSC, 1,012 (58%) received chemotherapy and 739 (42%) did not. Older age (HR 1.06), comorbidities (HR 1.31), larger tumor size (HR 1.27), lymphovascular invasion (HR 1.86), positive peritoneal cytology (HR 2.62), no pelvic lymph node dissection (HR 1.51), and no chemotherapy (HR 2.16) were associated with poorer prognosis. Compared to no chemotherapy, patients who underwent chemotherapy had a 5-year overall survival of 80% vs. 67%. To better delineate those who may derive more benefit from chemotherapy, we designed a clinical calculator capable of dividing patients into low, moderate, and high-risk groups with associated 5-year OS of 86%, 73%, and 53%, respectively. Using the calculator to assess the relative benefit of chemotherapy in each risk group, chemotherapy improved the 5-year OS in the high (42% to 64%; p < 0.001) and moderate risk group (66% to 79%; p < 0.001) but did not benefit the low risk group (84% to 87%; p = 0.29). CONCLUSION Our results suggest a clinical calculator is useful for counseling and personalizing chemotherapy for stage IA UPSC.

Abstract
Neuronal cell types are the nodes of neural circuits that determine the flow of information within the brain. Neuronal morphology, especially the shape of the axonal arbor, provides an essential descriptor of cell type and reveals how individual neurons route their output across the brain. Despite the importance of morphology, few projection neurons in the mouse brain have been reconstructed in their entirety. Here we present a robust and efficient platform for imaging and reconstructing complete neuronal morphologies, including axonal arbors that span substantial portions of the brain. We used this platform to reconstruct more than 1,000 projection neurons in the motor cortex, thalamus, subiculum, and hypothalamus. Together, the reconstructed neurons constitute more than 85 meters of axonal length and are available in a searchable online database. Axonal shapes revealed previously unknown subtypes of projection neurons and suggest organizational principles of long-range connectivity.

Abstract
Objective: This study examined the contribution of age, type of human papillomavirus (HPV), attachment, sexual satisfaction, and spirituality in dyadic adjustment in women with HPV from diagnosis to one year later. Method: This is a longitudinal study with three assessment moments: (T1) at the diagnosis appointment, (T2) six months after, and (T3) 12 months after the diagnosis. Participants answered a sociodemographic questionnaire as well as several other measures: HPV Knowledge Questionnaire (HPVQ), Papanicolaou Exam Knowledge Questionnaire (PEK-Q), Hospital Anxiety and Depression Scale (HADS), Courtauld Emotional Control Scale (CECS), Index of Sexual Satisfaction (ISS), Experiences in Close Relationship Scale-Short Form (ECR-S), Spiritual and Religious Attitudes in Dealing With Illness (SpREUK), and the Revised Dyadic Adjustment Scale (RDAS). Results: Age showed a positive impact on sexual dissatisfaction at T2. Sexual dissatisfaction at T1 predicted sexual dissatisfaction at T2 and dyadic adjustment at T3. Spirituality and insecure attachment at T1 negatively predicted insecure attachment at T2, and the latter predicted dyadic adjustment at T3. Conclusions: The results corroborate the need to assess the dyad when women are diagnosed with HPV. Only then it will be possible to design differentiated intervention programs that take into consideration women's age, attachment style, and sexual satisfaction. Interventions should also include women's partners to promote dyadic adjustment in this population.

Abstract
OBJECTIVE The purpose of this case report is to describe the management of using a combination of hip strengthening and manipulative therapy (MT) for a patient with plantar fasciitis. CLINICAL FEATURES A 44-year-old patient reported heel pain for approximately 1 year before treatment. The patient reported plantar heel pain and tenderness at the calcaneal tuberosity. The pain was most noticeable in the morning but was reduced after a 30-minute walk. A diagnosis of plantar fasciitis was made at the initial assessment. INTERVENTION AND OUTCOMES Initially, a clinical evaluation was performed to measure pain intensity (Numeric Pain Rating Scale), pressure-pain threshold (algometry), and perceived exertion (OMNI Resistance Exercise Scale). The patient then underwent 10 sessions of hip strengthening and MT over a period of 3 months. After the treatment, the intensity of pain and the pressure-pain threshold was reevaluated. The patient reported an improvement in pain intensity (baseline score = 6 vs final score = 1) and an increase in the pressure-pain threshold (initial score = 2.6 vs final score = 7.1). Perceived exertion was also improved after hip muscle strength training (initial score = 10 vs final score = 8). CONCLUSION The combination of hip strengthening and MT improved foot pain in a patient with a clinical diagnosis of plantar fasciitis.

Abstract
Background Functional foods with bioactive properties may help in treat obesity, as they can lead to a decreased risks of inflammatory diseases. The aim of this study was to investigate the effects of chitosan coacervate whey protein on the proinflammatory processes in mice fed with high-fat diet. Methods Mice were divided into two groups receiving either a normolipidic or high-fat diet; the animals in each of the two diet groups were given a diet supplement of either coacervate (gavage, 36 mg protein/kg of body weight) or tap water for four weeks [groups: normolipidic diet plus water (C); normolipidic diet and coacervate (CC); high-fat diet and water (H); and high-fat diet and coacervate (HC)]. Results The high-fat diet promoted inflammation, possibly by decreased adiponectin/sum of adipose tissues ratio and increased phosphorylation of NF-κB p50. In HC we observed a positive correlation between IL-10 and TNF-α in mesenteric adipose tissue, retroperitoneal adipose tissue and liver tissue. We also observed a positive correlation between lipopolisaccharide with IL-10 in the liver tissue. Conclusions High-fat diet treatment promoted metabolic alterations and inflammation, and chitosan coacervate whey protein modulated inflammatory milieu.

Abstract
Background Previously, we demonstrated that trans fatty acid ingestion during pregnancy and lactation caused a pro-inflammatory effect on the newborn. The opposite effect was described for gestational prebiotic intake. In the present study, we examined whether supplementation of the diet of the dams with 10% of oligofructose with or without hydrogenated vegetable fat during pregnancy and lactation affected the pro-inflammatory status on the pups at age 21 days. Methods On the first day of pregnancy, rats were divided into four groups, each of which received one of four diets: a control diet (C group), a control diet supplemented with 10% oligofructose (CF group), a diet enriched with hydrogenated vegetable fat containing trans fatty acids (T group) or a diet enriched with hydrogenated vegetable fat containing trans fatty acids supplemented with 10% oligofructose (TF group). The pups were weighed at birth and at 7, 14 and 21 days of life and were euthanized on post-natal day 21. The serum glucose, insulin and adiponectin concentrations were analyzed. The IL-6, IL-10 and TNF-α contents of the retroperitoneal white adipose tissue, liver, soleus and extensor digital longus muscles were analyzed by ELISA. The results are presented as the means ± standard error of the mean. Statistical significance was assessed using two-way ANOVA, followed by Tukey's test and considered significant at p < 0.05 Results The body weights of the 21-day old pups in the CF and TF groups were significant lower than those of the C (27% and 21%) and T (25% and 19%, respectively) groups. The serum levels of adiponectin in the CF, T and TF groups were lower than in the C group (41%; 34% and 31%, respectively). In the retroperitoneal adipose tissue, the IL-6 content was increased in TF group relative to the C and CF groups (74% for both), and the TNF-α content was higher in the T and TF groups than in the C group (62% and 98%, respectively). In the liver, the TNF-α (56% and 104%) and IL-10 (52% and 73%) contents were increased in the CF group relative to the C and TF groups. Conclusions Supplementation of the diet of the dams with 10% of oligofructose during pregnancy and lactation, independent of supplementation with hydrogenated vegetable fat, adversely affected the development of the offspring and contributed to development of a pro-inflammatory status in the pups on postnatal day 21.

Abstract
Caspases are cysteine proteinases that play a critical role in the execution phase of apoptosis. The active site cysteine residue must be reduced for caspase activity. Thioredoxins are redox proteins that catalyze the reduction of cysteine residues. We have examined the ability of various recombinant human thioredoxins to activate caspase-3. The EC(50) for caspase-3 activation by reduced thioredoxin-1 was 2.5 microM, by reduced glutathione 1.0 mM and by dithiothreitol 3.5 mM. A catalytic site redox-inactive mutant thioredoxin-1 was almost as active as thioredoxin-1 in activating caspase-3. Caspase activation was shown to correlate with the number of reduced cysteine residues in the thioredoxins. Reduced insulin and serum albumin were as effective on a molar basis as thioredoxin-1 in activating caspase-3. Thus, caspase-3 activation is not a specific effect of thioredoxins but is a property shared by other reduced proteins.
