Abstract
Mary, who experienced non-fluent aphasia as a result of an ischemic stroke, received 10 years of personalized language training (LT), resulting in transient enhancements in speech and comprehension. To enhance these effects, multisite transcranial Direct Current Stimulation (tDCS) was added to her LT regimen for 15 sessions. Assessment using the Reliable Change Index showed that this combination improved her left inferior frontal connectivity and speech production for two months and significantly improved comprehension after one month. The results indicate that using multisite transcranial direct current stimulation (tDCS) can improve the effectiveness of language therapy (LT) for individuals with non-fluent aphasia.

Abstract
This work reports a pressure-dependent Raman spectroscopic study and the theoretical lattice dynamics calculations of a Bi2(MoO4)3 crystal. The lattice dynamics calculations were performed, based on a rigid ion model, to understand the vibrational properties of the Bi2(MoO4)3 system and to assign the experimental Raman modes under ambient conditions. The calculated vibrational properties were helpful to support pressure-dependent Raman results, including eventual structural changes induced by pressure changes. Raman spectra were measured in the spectral region between 20 and 1000 cm-1 and the evolution of the pressures values was recorded in the range of 0.1-14.7 GPa. Pressure-dependent Raman spectra showed changes observed at 2.6, 4.9 and 9.2 GPa, these changes being associated with structural phase transformations. Finally, principal component analysis (PCA) and hierarchical cluster analysis (HCA) were performed to infer the critical pressure of phase transformations undergone by the Bi2(MoO4)3 crystal.

Abstract
Dietary self-control is associated with inter-individual differences in neuroanatomy. Yet, whether such inter-individual differences are also associated with healthier dietary patterns is yet to be determined. In this cross-sectional study, a total of 100 northern Portuguese older community-dwellers were assessed with regards to i) the adherence to a healthy dietary eating pattern - the Mediterranean diet (MedDiet), and ii) grey matter density (GMD) of brain regions associated with valuation and dietary self-regulation, the ventromedial (vmPFC) and dorsolateral prefrontal cortex (dlPFC), through voxel-based morphometry. Healthy food choices were ascertained through the Mediterranean Diet Adherence Screener (MEDAS) where higher scores indicated greater adherence to the MedDiet. Voxel-based morphometry showed that greater grey matter density in the dlPFC and vmPFC associated with a higher adherence to the MedDiet. These results replicate previous links between dietary decision-making measured under laboratory conditions and the neuroanatomy of the brain's valuation and self-control system. Importantly, they shed new light on the potential relevance of inter-individual differences in the neuroanatomy of these two brain regions for adhering to healthier dietary patterns in everyday life.

Abstract
The significant link between stress and psychiatric disorders has prompted research on stress's impact on the brain. Interestingly, previous studies on healthy subjects have demonstrated an association between perceived stress and amygdala volume, although the mechanisms by which perceived stress can affect brain function remain unknown. To better understand what this association entails at a functional level, herein, we explore the association of perceived stress, measured by the PSS10 questionnaire, with disseminated functional connectivity between brain areas. Using resting-state fMRI from 252 healthy subjects spanning a broad age range, we performed both a seed-based amygdala connectivity analysis (static connectivity, with spatial resolution but no temporal definition) and a whole-brain data-driven approach to detect altered patterns of phase interactions between brain areas (dynamic connectivity with spatiotemporal information). Results show that increased perceived stress is directly associated with increased amygdala connectivity with frontal cortical regions, which is driven by a reduced occurrence of an activity pattern where the signals in the amygdala and the hippocampus evolve in opposite directions with respect to the rest of the brain. Overall, these results not only reinforce the pathological effect of in-phase synchronicity between subcortical and cortical brain areas but also demonstrate the protective effect of counterbalanced (i.e., phase-shifted) activity between brain subsystems, which are otherwise missed with correlation-based functional connectivity analysis.

Abstract
Daily routines are getting increasingly stressful. Interestingly, associations between stress perception and amygdala volume, a brain region implicated in emotional behaviour, have been observed in both younger and older adults. Life stress, on the other hand, has become pervasive and is no longer restricted to a specific age group or life stage. As a result, it is vital to consider stress as a continuum across the lifespan. In this study, we investigated the relationship between perceived stress and amygdala size in 272 healthy participants with a broad age range. Participants were submitted to a structural magnetic resonance imaging (MRI) to extract amygdala volume, and the Perceived Stress Scale (PSS) scores were used as the independent variable in volumetric regressions. We found that perceived stress is positively associated with the right amygdala volume throughout life.

Abstract
Background: Numerous studies suggest a relationship between depression and metabolic syndrome, which is likely influenced by age. Interestingly, functional imaging analysis has shown an association between functional connectivity in the default mode network (DMN-FC) and components of metabolic syndrome, which is explored in this study. Methods: From a larger longitudinal cohort study on healthy aging, 943 individuals were extensively characterized for mood and cognition. Among these, 120 individuals who were selected for displaying extreme cognitive performance within the normal range (good and poor performers) were further studied. Here, in a cross-sectional design, using confirmatory factor analysis (CFA), the association between metabolic dysfunction and depressive mood as a function of age and its relationship with DMN-FC was studied. Results: Metabolic dysfunction was modeled as a second-order latent variable using CFA. First-order latent variables were obesity, glucose dysmetabolism, lipids imbalance, and blood pressure. Using multiple linear regression models, this study observed that metabolic dysfunction, glucose dysmetabolism, and lipids imbalance were linearly associated with depressive mood, and the association with obesity was U-shaped. The association of metabolic dysfunction, obesity, and glucose dysmetabolism with depressive mood is positive for the younger individuals in our sample and vanishes with aging. The FC of the right superior temporal gyrus with the DMN correlated with both obesity and depressive mood. In participants with higher obesity scores, FC increased with higher GDS scores, while in those with lower GDS scores, FC decreased. Age and blood pressure were associated with a more complex pattern of association between FC of the right supramarginal gyrus and GDS score. Conclusion: The association of metabolic dysfunction with depressive mood is influenced by age and relates with differential patterns of DMN-FC. The combination of the effects of age, mood, and metabolic dysfunction is likely to explain the heterogeneity of DMN-FC, which deserves further investigation with larger and longitudinal studies.

Abstract
We investigate the magnetic nanoparticles hyperthermia in a non-adiabatic and radiating process through the calorimetric method. Specifically, we propose a theoretical approach to magnetic hyperthermia from a thermodynamic point of view. To test the robustness of the approach, we perform hyperthermia experiments and analyse the thermal behavior of magnetite and magnesium ferrite magnetic nanoparticles dispersed in water submitted to an alternating magnetic field. From our findings, besides estimating the specific loss power value from a non-adiabatic and radiating process, thus enhancing the accuracy in the determination of this quantity, we provide physical meaning to a parameter found in literature that still remained not fully understood, the effective thermal conductance, and bring to light how it can be obtained from experiment. In addition, we show our approach brings a correction to the estimated experimental results for specific loss power and effective thermal conductance, thus demonstrating the importance of the heat loss rate due to the thermal radiation in magnetic hyperthermia.

Abstract
Stress is inevitably linked to life. It has many and complex facets. Notably, perception of stressful stimuli is an important factor when mounting stress responses and measuring its impact. Indeed, moved by the increasing number of stress-triggered pathologies, several groups drew on advanced neuroimaging techniques to explore stress effects on the brain. From that, several regions and circuits have been linked to stress, and a comprehensive integration of the distinct findings applied to common individuals is being pursued, but with conflicting results. Herein, we performed a volumetric regression analysis using participants’ perceived stress as a variable of interest. Data shows that increased levels of perceived stress positively associate with the right amygdala and anterior hippocampal volumes. Discrepant stress effects on morphology are reported in the literature. Stress definition and analysis software are the main causes of conflicting findings. Psychological measures and multi-technique analysis are highly recommended. We found that perceived stress positively associates with right amygdala volumes.

Abstract
The Mediterranean diet (MedDiet) has been associated with cognitive performance. Yet, controlled trials have yielded contradictory results. To tackle this controversy, a comprehensive multimodal analysis of the association of the MedDiet with cognitive performance and brain structure in normative aging is still necessary. Here, community dwellers ≥50 years from a cohort study on normative aging (n = 76) underwent a (i) magnetic resonance imaging session with two acquisitions: structural and diffusion-weighted imaging (DWI); (ii) neuropsychological battery of tests focusing on memory and executive functioning; and (iii) dietary assessment through the Mediterranean Diet Assessment Screener (MEDAS, score range: 0-14, scores ≥10 indicate high adherence to the Mediterranean diet) 18 months prior to the brain imaging and neuropsychological assessment. We found that high adherence to the MedDiet (MEDAS ≥10) was associated with higher values of fractional anisotropy and lower diffusivity values in the brain white matter. Similarly, high adherence to the MedDiet was associated with higher structural connectivity between left hemisphere brain regions. Specifically, the amygdala, lingual, olfactory, middle occipital gyrus, and calcarine areas. No association was found between high adherence to the MedDiet and total brain volumes or hypointensities. Higher adherence to the MedDiet was positively associated with executive functioning scores. These results suggest that high adherence to the MedDiet positively associates with brain health, specifically with executive function scores and white matter integrity of bundles related to the processing and integration of taste, reward, and decision making. These findings seem to support the view that the MedDiet should be part of recommendations to promote a healthy brain.

Abstract
Previous research showed that the ability to make inferences about our own and other’s mental states rely on common brain pathways; particularly in the case of close relationships (e.g., romantic relationships). Despite the evidence for shared neural representations of self and others, less is known about the distributed processing within these common neural networks, particularly whether there are specific patterns of internode communication when focusing on other vs. self. This study aimed to characterize context-sensitive coupling among social brain regions involved in self and other understanding. Participants underwent an fMRI while watching emotional video vignettes of their romantic partner and elaborated on their partner’s (other-condition) or on their own experience (self-condition). We used dynamic causal modeling (DCM) to quantify the associated changes in effective connectivity (EC) in a network of brain regions involved in social cognition including the temporoparietal junction (TPJ), the posterior cingulate (PCC)/precuneus and middle temporal gyrus (MTG). DCM revealed that: the PCC plays a central coordination role within this network, the bilateral MTG receives driving inputs from other nodes suggesting that social information is first processed in language comprehension regions; the right TPJ evidenced a selective increase in its sensitivity when focusing on the other’s experience, relative to focusing on oneself.

Abstract
BACKGROUND Patients with obsessive–compulsive disorder (OCD) employ ritualistic behaviours to reduce or even neutralize the anxiety provoked by their obsessions. The presence of excessive rumination and indecision has motivated the view of OCD as a disorder of decision-making. Most studies have focused on the “cold,” cognitive aspects of decision-making. This study expands current understanding of OCD by characterizing the abnormalities associated with affective, or “hot” decision-making. METHODS We performed a functional MRI study in a sample of 34 patients with OCD and 33 sex- and age-matched healthy controls, during which participants made 2-choice gambles taking varying levels of risk. RESULTS During risky decisions, patients showed significantly reduced task-related activation in the posterior cingulum, lingual gyrus and anterior cingulate cortex. We identified significant group × risk interactions in the calcarine cortex, precuneus, amygdala and anterior cingulate cortex. During the outcome phase, patients with OCD showed stronger activation of the orbitofrontal cortex, anterior cingulate cortex and putamen in response to unexpected losses. LIMITATIONS The group of patients not receiving medication was very small (n = 5), which precluded us from assessing the effect of medication on risk-taking behaviour in these patients. CONCLUSION Obsessive–compulsive disorder is associated with abnormal brain activity patterns during risky decision-making in a set of brain regions that have been consistently implicated in the processing of reward prediction errors. Alterations in affective “hot” processes implicated in decision-making may contribute to increased indecisiveness and intolerance to uncertainty in patients with OCD.

Abstract
Obsessive-compulsive disorder (OCD) is one of the most debilitating psychiatric conditions, having a dramatic impact on patients' daily living. In this work, we aimed to explore resting-state functional connectivity in OCD patients, using an independent component analysis. Eighty individuals (40 patients and 40 healthy controls) performed a resting state fMRI protocol. OCD patients displayed reduced functional connectivity (FC) in visual and sensorimotor networks. In addition, patients displayed decreased FC between sensory networks and increased FC between default-mode and cerebellar networks.

Abstract
Social interactions require the capacity to understand both our and other's internal states. These semi-independent skills, the ability to understand oneself and others, seem to rely on the same type of representations and recruit similar brain areas. In this study, we looked at the neural basis of self and other processing in the context of an interaction with a significant other. Fourty-two participants in a monogamous relationship completed an fMRI task in which they watched a set of video-vignettes of his/her romantic partner expressing emotional contents. Participants were asked to elaborate on his/her spouse´s experience (other condition) and on his/her own experience when watching the video-vignettes (self-condition). The results showed a significant overlap in the brain activation for both conditions (e.g. anterior insula, posterior cingulate/precuneus, inferior frontal gyrus, inferior parietal lobule). In addition, the self-condition recruited brain areas associated with interoceptive processing and affect sharing (e.g., posterior insula), whereas the other-condition engaged brain areas involved in the cognitive representation of another's internal states and self-other distinction (e.g., fusiform, supramarginal gyrus, angular gyrus and temporoparietal junction).

Abstract
Resting state brain networks are implicated in a variety of relevant brain functions. Importantly, abnormal patterns of functional connectivity (FC) have been reported in several neurodevelopmental disorders. In particular, the Default Mode Network (DMN) has been found to be associated with social cognition. We hypothesize that the DMN may be altered in Williams syndrome (WS), a neurodevelopmental genetic disorder characterized by an unique cognitive and behavioral phenotype. In this study, we assessed the architecture of the DMN using fMRI in WS patients and typically developing matched controls (sex and age) in terms of FC and volumetry of the DMN. Moreover, we complemented the analysis with a functional connectome approach. After excluding participants due to movement artifacts (n = 3), seven participants with WS and their respective matched controls were included in the analyses. A decreased FC between the DMN regions was observed in the WS group when compared with the typically developing group. Specifically, we found a decreased FC in a posterior hub of the DMN including the precuneus, calcarine and the posterior cingulate of the left hemisphere. The functional connectome approach showed a focalized and global increased FC connectome in the WS group. The reduced FC of the posterior hub of the DMN in the WS group is consistent with immaturity of the brain FC patterns and may be associated with the singularity of their visual spatial phenotype.

Abstract
OBJECTIVE To assess the effects of isoflavones and 17β-estradiol on the vaginal epithelium extracellular matrix and hyaluronic acid (HA) in the diabetic rat model. METHODS Sixty adult, virgin, female rats underwent ovariectomy, then randomization into six groups of ten animals each: GI, sham ovariectomized control animals; GII, sham ovariectomized control diabetic animals; GIII, control ovariectomized rats receiving propylene glycol vehicle; GIV, control ovariectomized diabetic animals receiving propylene glycol vehicle; GV, diabetic ovariectomized animals treated with soy isoflavones (150 mg/kg by gavage); GVI, ovariectomized diabetic rats treated with estrogen (17β-estradiol, 10 mg/kg, subcutaneously). Treatment took place over 30 consecutive days. After euthanasia, a portion of the vagina was immersed in liquid nitrogen for RT-qPCR and Western blotting. Another portion was processed for paraffin embedding. Sections were stained with hematoxylin & eosin for histomorphometry and Picro Sirius Red for collagen quantification. RESULTS Vaginal epithelium histomorphometry in GIII (15.3 ± 1.1 µm) and GIV (14.5 ± 1.8 µm) was thinner than in GV (41.3 ± 1.5 µm) and GVI (74.3 ± 1.6 µm). There was an increase in collagen content in GV (84.1 ± 1.2 µm) and GVI (88.2 ± 1.7 µm). HA quantification was higher in GV (0.38 ± 1.1 μg/mg) and GVI (0.49 ± 1.4 μg/mg) when compared with GIII (0.12 ± 1.1 μg/mg) and GIV (0.10 ± 1.2 μg/mg), p < 0.05. CONCLUSIONS Soy isoflavones increase hyaluronic acid concentration in the vagina of diabetic ovariectomized rats. Such findings might help to attenuate the effects of vulvovaginal atrophy in women.

Abstract
Obsessive-compulsive disorder (OCD) is one of the most debilitating psychiatric conditions. An extensive body of the literature has described some of the neurobiological mechanisms underlying the core manifestations of the disorder. Nevertheless, most reports have focused on individual modalities of structural/functional brain alterations, mainly through targeted approaches, thus possibly precluding the power of unbiased exploratory approaches. Eighty subjects (40 OCD and 40 healthy controls) participated in a multimodal magnetic resonance imaging (MRI) investigation, integrating structural and functional data. Voxel-based morphometry analysis was conducted to compare between-group volumetric differences. The whole-brain functional connectome, derived from resting-state functional connectivity (FC), was analyzed with the network-based statistic methodology. Results from structural and functional analysis were integrated in mediation models. OCD patients revealed volumetric reductions in the right superior temporal sulcus. Patients had significantly decreased FC in two distinct subnetworks: the first, involving the orbitofrontal cortex, temporal poles and the subgenual anterior cingulate cortex; the second, comprising the lingual and postcentral gyri. On the opposite, a network formed by connections between thalamic and occipital regions had significantly increased FC in patients. Integrative models revealed direct and indirect associations between volumetric alterations and FC networks. This study suggests that OCD patients display alterations in brain structure and FC, involving complex networks of brain regions. Furthermore, we provided evidence for direct and indirect associations between structural and functional alterations representing complex patterns of interactions between separate brain regions, which may be of upmost relevance for explaining the pathophysiology of the disorder.

Abstract
Obsessive-compulsive personality (OCPD) disorder is characterized by a pattern of excessive self-control, perfectionism and behavioral and cognitive rigidity. Despite the fact that OCPD is the most common personality disorder in the general population, published studies looking at the brain correlates of this disorder are practically nonexistent. The main goal of this study was to analyze the presence of brain alterations in OCPD when compared to healthy controls, specifically at the level of the Default Mode Network (DMN). The DMN is a well-established resting state network which was found to be associated with psychological processes that may play a key role in OCPD (e.g., self-awareness, episodic future thinking and mental simulation). Ten individuals diagnosed with OCPD and ten healthy controls underwent a clinical assessment interview and a resting-state functional magnetic resonance imaging (fMRI) acquisition. The results show that OCPD patients presented an increased functional connectivity in the precuneus (i.e., a posterior node of the DMN), known to be involved in the retrieval manipulation of past events in order to solve current problems and develop plans for the future. These results suggest that this key node of the DMN may play an important role in the pathophysiology of OCPD.

Abstract
Melatonin is an indolamine produced by the pineal gland and it can exert a potent antioxidant effect. Its free radical scavenger properties have been used to advantage in different organ transplants in animal experiments. Several concentrations and administration pathways have been tested and melatonin has shown encouraging beneficial results in many transplants of organs such as the liver, lungs, heart, pancreas, and kidneys. The objective of the present study was to review the scientific literature regarding the use of melatonin in ovary transplantation. A systematic review following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was carried out using the Cochrane and Pubmed databases and employing the terms 'melatonin' AND 'ovary' AND 'transplantation.' After analysis, 5 articles were extracted addressing melatonin use in ovary transplants and involving 503 animals. Melatonin enhanced various graft aspects like morphology, apoptosis, immunological reaction, revascularization, oxidative stress, and survival rate. Melatonin's antioxidative and antiapoptotic properties seemingly produce positive effects on ovarian graft activity. Despite the promising results, further studies in humans need to be conducted to consolidate its use, as ovary transplantation for fertility preservation is gradually being moved from the experimental stage to a clinical setting.

Abstract
Aging of brain structure and function is a complex process characterized by high inter- and intra-individual variability. Such variability may arise from the interaction of multiple factors, including exposure to stressful experience and mood variation, across the lifespan. Using a multimodal neuroimaging and neurocognitive approach, we investigated the association of stress, mood and their interaction, in the structure and function of the default mode network (DMN), both during rest and task-induced deactivation, throughout the adult lifespan. Data confirmed a decreased functional connectivity (FC) and task-induced deactivation of the DMN during the aging process and in subjects with lower mood; on the contrary, an increased FC was observed in subjects with higher perceived stress. Surprisingly, the association of aging with DMN was altered by stress and mood in specific regions. An increased difficulty to deactivate the DMN was noted in older participants with lower mood, contrasting with an increased deactivation in individuals presenting high stress, independently of their mood levels, with aging. Interestingly, this constant interaction across aging was globally most significant in the combination of high stress levels with a more depressed mood state, both during resting state and task-induced deactivations. The present results contribute to characterize the spectrum of FC and deactivation patterns of the DMN, highlighting the crucial association of stress and mood levels, during the adult aging process. These combinatorial approaches may help to understand the heterogeneity of the aging process in brain structure and function and several states that may lead to neuropsychiatric disorders.

Abstract
Abstract
Introduction. The implementation of Nipple-Sparing Mastectomy (NSM) as a treatment option for selected cases of breast cancer has risen great interest among breast surgeons. The preservation of the nipple-areola complex (NAC) can lead to extremely favorable psychological effects in breast cancer patients treated with this type of procedure. However, to ensure the oncologic safety of this technique it is of utmost importance to evaluate the likelihood of NAC involvement pre-operatively. In this study we evaluate the contribution of Breast Magnetic Resonance Imaging (MRI) in predicting the involvement in the NAC in breast cancer patients. Materials and Methods: We studied 170 mastectomy specimens from 165 breast cancer patients (five patients had bilateral disease) affected by Ductal Carcinoma in situ (DCIS)(n=19) or Invasive Ductal Carcinoma (n=151), stages I, II or IIIA. Every patient was pre-operatively studied using a 1.5 Tesla, 4-channel in vivo dedicated surface breast coil MRI. The parameters we investigated were: type of index lesion enhancement pattern (nodular or non-nodular), size of the index lesion, enhancement between the index lesion and the NAC, enhancement of the nipple, thickening of the areola, nipple retraction and size of the nipple in comparison with the contra-lateral nipple. The retro-areolar area and papilla were evaluated in histological sections of 4μm to identify DCIS and Invasive Ductal or Lobular carcinomas. One radiologist, blinded to the result of the histological evaluation of the papillae, performed the evaluation of the MRIs. Results. In univariate analysis, type of lesion enhancement in MRI, enhancement between index lesion and the papilla, distance between the index lesion and the papilla, enhancement of the papilla and nipple retraction had a statistically significant correlation with neoplastic involvement of the NAC (p<0.05). Using multivariate analysis, among the previously mentioned parameters, enhancement between the index lesion and the NAC, and nipple retraction remained as statistically significant predictors of nipple involvement in breast cancer patients (p < 0,001 e 0,010, respectively). The Negative Predictive Value of the combination of these two variables was 89.5%. According to this model that used the combination of those two variables, the probability of neoplastic involvement of the NAC was 73.9% in the presence of enhancement between the index lesion and the papilla combined with nipple retraction; 46% in the presence of enhancement between the index lesion and the papilla without nipple retraction in the MRI; 26.9% if there is only nipple retraction in the MRI; and 9.9% in the absence of these two characteristics. The sensibility of this model composed by those 2 variables to identify neoplastic involvement of the NAC was 29.7% (CI95%: 15.9% - 47%), specificity was 97.7% (CI95%: 93,5% - 99,5%), positive predictive value was 78,6% (CI95%: 49,2% - 95,3%) and negative predictive value was 83,3% (CI95%: 76,5% - 88,8%).
Conclusion. We can conclude that the probability of the NAC being cancer-free is around 90% when there is no enhancement between the index lesion and the nipple, and there is no retraction of the nipple in the pre-operative MRI study of the breast.

Abstract
Abstract
Introduction: Development of the nipple-sparing mastectomy (NSM) technique has constituted a significant advance in the surgical treatment of selected cases of breast cancer. The most important aspect of areolar complex preservation is the exclusion of carcinoma involving the nipple. The retroareolar surgical margin is usually sampled and subjected to an intraoperative evaluation by frozen section examination in order to avoid a second procedure. However, this method is not standardized resulting in variable rates of false-negative results. Here, a new technique is proposed for the intraoperative study of the retroareolar margin. This ex vivo study was conducted by performing a simulated NSM procedure for patients undergoing total mastectomy to assess the impact of these measures on the accuracy of retroareolar frozen section examination. Materials and Methods: Between September 2012 and April 2014, we studied 158 mastectomy specimens from patients undergoing total mastectomy for breast cancer at the Cancer Institute of the State of São Paulo. Inclusion criteria were stage Tis-T3 tumors, multifocal and multicentric breast carcinoma, unicentric carcinoma not suitable to quadrantectomy. Patients submitted to neoadjuvant chemotherapy were also included. To obtain the entire sample area, the terminal retroareolar milk duct bunch was isolated. Fragments approximately 1.5 cm in length were excised and sectioned in parallel at the base of the nipple using a cold bistoury. Three transverse histological sections (4 μm each) at 200 μm intervals that included the entire isolated fragments were subjected to frozen section examination. The sections were stained with hematoxylin-eosin (H&E) and were evaluated. The remainder of each fragment was embedded in paraffin and 4 μm sections were subsequently stained with H&E and examined. Results: A total of 158 mastectomy specimens involving mammary carcinoma of no special type were examined. These included 15 (9.5%) in situ stage tumors, 36 (22.8%) stage I tumors, 71 (44.9%) stage II tumors, and 36 (22.8%) stage IIIA tumors. Paraffin examinations identified 25 retroareolar fragments compromised by carcinoma, resulting in 16.1% prevalence. Of the frozen sections examined, 2/158 (1.3%) had false-negative results and 5/158 (3.1%) had false-positive results. For the former two cases, the corresponding paraffin examinations detected low-grade carcinoma in situ and a residual cell cluster with a diameter less than 1 mm. The latter was found in a mastectomy specimen from a patient that underwent neoadjuvant chemotherapy. For the three cases involving false-positive results, the corresponding paraffin examinations revealed no atypical ductal hyperplasia present, one sclerosing intraductal papilloma and one nipple syringomatous adenoma. Statistical analysis revealed that the frozen section examinations performed had a sensitivity rate of 92.0% and a specificity rate of 96.2%. In addition, the positive predictive value (PPV) was 82.1%, the negative predictive value (NPV) was 98.4%, and the accuracy was 95.4%. Conclusion: The frozen section examination technique described here detected nipple involvement in breast cancer with greater accuracy than the frozen section usually performed by most surgeons.

Abstract
OBJECTIVE We evaluated whether genistein or estrogen treatment has the same effect when administered immediately or late to rats induced with menopause using ovariectomy. METHODS Sixty adult female rats were divided into six treatment groups: GI = vehicle immediately after ovariectomy; GII = vehicle 30 days after ovariectomy; GIII = genistein immediately after ovariectomy; GIV = genistein 30 days after ovariectomy; GV = estrogen immediately after ovariectomy; and GVI = estrogen 30 days after ovariectomy. All animals were treated for 30 consecutive days. At the end of the treatment, part of the uteri was removed for subsequent histological studies and another part was used to evaluate estrogen receptors 1 and 2, cell proliferation (cyclin A1 and A2, cyclin D1, cyclin-dependent kinase inhibitors 1, 1B and 2, antigen identified by the monoclonal antibody Ki67) and angiogenesis (vascular endothelial growth factor, VEGF-A) gene expression. RESULTS Late treatment after castration in rats resulted in more developed endometrium, enhanced cell proliferation and estrogen-signalling pathways, particularly the cyclin-related genes Ki67 and VEGF-A, compared to early treatment. Interestingly, these same effects were less intense with genistein compared to those induced by estrogen, especially when genistein was administered late. CONCLUSION Our data show that isoflavone renders a lower risk of cancer when compared to estrogen in treatments.

Abstract
BACKGROUND The genesis of the endometrial polyp is as yet unclear. There is evidence that the polyp is related to the inflammatory process and that it interacts with the cyclooxygenase-2 (COX-2) enzyme. OBJECTIVE To review the influence of COX-2 on the postmenopausal endometrial polyp. METHODS A systematic review was made of the Medline, Embase, and Cochrane databases, covering the years of 2001-2014. The inclusion criteria were: experimental studies with immunohistological analysis of COX-2 in endometrial polyps; women; hysteroscopic and surgical evaluation; and studies with comparisons between the endometrial polyp and other tissues (normal endometrium, adjacent endometrium, and other uterine diseases). The exclusion criteria were: polyps in other organs; genetic polymorphisms; endometrial cancer exclusively; abnormal uterine bleeding unrelated to polyps. The search key words (taken from the Medical Subject Headings - MeSH) were endometrial polyp and cyclooxygenase-2. RESULTS Seven of ten articles were selected. Results showed positive COX-2 expression in the glandular epithelium of the polyps, and expression was more intense when the polyp was malignant. However, there was a study which did not find any difference between polyps and the normal endometrium, and there was another which compared polyps in menacme with postmenopausal polyps. CONCLUSION There is no consensus in the literature as to the participation of COX-2 in the development of benign and/or malignant endometrial polyps. In all of the studies, COX-2 was present in the postmenopausal polyps and with greater intensity in the malignant ones.

Abstract
AIM The objective of this study was to evaluate the impact of clinical variables on survival rates in patients with squamous cell carcinomas in the lower oral cavity. METHODS We conducted a retrospective study of patients who exhibited a histological diagnosis of squamous cell carcinoma of the lower oral cavity, who underwent surgery. Data on clinical, histological, and treatment variables were collected to assess the effect of these variables on global survival and disease-free curves. RESULTS We studied 117 patients, 86 (73.5%) males and 31 (26.5%) females, who underwent surgery between January 2005 and June 2009. The overall survival rate was 74.4% after two years, and the disease-free rate was 67.5%. Midline invasion by the primary tumor negatively impacted overall survival (P=0.02) and disease-free survival (P=0.01). The disease-free survival rate of patients with histologically confirmed neck metastases was 76.8% versus 59% for patients without metastases (P=0.01). Disease-free survival of patients with one affected lymph node was 89.5%, and 45.2% for more than one affected lymph node (P<0.01). Patients who ended radiotherapy in less than 60 days exhibited a disease-free rate of 59.0%, and patients whose treatment lasted more than 60 days exhibited a rate of 77.1% (P=0.06). CONCLUSION In our study, primary tumor invasion of the midline, the presence of more than one affected lymph node as confirmed by histology, the delaying radiotherapy for more than 56 days and radiotherapy that lasted longer than 60 days worsen patient prognosis.

Abstract
OBJECTIVE To evaluate the effects of soy isoflavone extract in the pro-oxidant/antioxidant balance in the uterus of ovariectomized rats. METHODS Twenty 3-month-old adult female Wistar rats were divided into four equal groups: GI: sham-operated (estrous phase); GII: control ovariectomized rats; GIII: ovariectomized rats treated with genistein (50 μg/kg/day) by gavage; GIV: ovariectomized rats subcutaneously treated with estrogen (10 μg/kg/day). After 30 consecutive days of treatment, the rats were euthanized and the uterus removed. The distal thirds of the uterine horns were processed for histomorphometric analyses of endometrial and myometrial thicknesses and glandular area. Other regions of the uteri were kept in liquid nitrogen and subsequently processed for analysis of reactive species quantification (DCF), total antioxidant capacity (TAC) and lipid oxidation status (TBARS). Data were statistically analyzed by one-way ANOVA, complemented by the Tukey-Kramer test (p < 0.05). RESULTS GII and GIII exhibited lower endometrial thickness, glandular area and myometrial thickness than GI and GIV, while a higher myometrial thickness was observed in GIV compared with the other groups. Moreover, the isoflavone-treated group showed lower DCF and TBARS compared to GII, and also an improvement of TAC compared to GI and GIV. Despite the significant decrease in TBARS, no significant difference in DCF nor a decrease in TAC were observed in GIV when compared to GII. CONCLUSION Our data show that isoflavones improve antioxidant status and counteract oxidative stress, without promoting a trophic effect in the uterus of rats.

Abstract
Individuals with Williams syndrome (WS) present a set of cognitive, affective and motor symptoms that resemble those of patients with lesions to the cerebellum. Although there is some evidence for overall structural alterations in this brain region in WS, explorations on cerebellar white matter and cerebellar cortex volumes remain rather neglected. We aimed to compare absolute and relative cerebellar volumes, as well as patterns of white matter to cortex volumes in this brain region, between a group of individuals with WS and a group of healthy controls. T1-weighted magnetic resonance images were acquired in 17 individuals with WS and in 15 typically developing individuals. Our results showed that even though individuals from the clinical group had significantly smaller cerebrums (and cerebellums), cerebellar volumes relative to intracranial volumes were significantly enlarged. In addition, while gray matter was relatively spared and white matter disproportionately reduced in the cerebrum in WS, relative cerebellar cortex and white matter volumes were preserved. These findings support the hypothesis that volume alterations in the cerebellum are associated with the cognitive, affective and motor profiles in WS.

Abstract
OBJECTIVE To evaluate whether soybean extracts and estrogens present additive effects on adult rat uterus. METHODS Fifty ovariectomized rats were randomly divided into five equal groups of ten animals: Control, treated with vehicle; SE46 and SE120, treated with 46 and 120 mg/kg soybean concentrated extract (SE), respectively; EE, treated with conjugated equine estrogens (CE) 50 μg/kg; SE120 + EE, treated with 50 μg/kg (CE) plus 120 mg/kg SE. The substances were administered daily by gavage for 21 consecutive days. Thereafter the animals were weighed and killed by decapitation; trunk blood was collected for hormone determinations. Uteri were removed immediately and fixed in 10% formaldehyde, followed by dehydration, embedding in paraffin and 6-m sections staining with hematoxylin and eosin for histomorphometric analyses of myometrium and endometrium. After ANOVA analysis of the data, the study was complemented with the Tukey-Kramer test for multiple comparisons. RESULTS The concentrated extract of soybean at high concentration (SE 120 kg/mg) and estrogens proved to have a trophic effect on the uterus (endometrium and myometrium) of castrated rats. In groups SE120, EE and SE120 + EE, all morphometric parameters examined (number of glands, eosinophils, blood vessels and the glandular area) were increased. No significant addictive effects of soybean extract plus estrogens were detected in the SE120 + EE group. CONCLUSIONS Our results indicate that soy extract has a trophic effect on rat uterine structures. Treatment of ovariectomized rats with a concentrated soy extract in combination with conjugated estrogens had no addictive effect on the uterine response.

Abstract
OBJECTIVE To evaluate p53 protein expression in the endometrial polyp and compare with adenocarcinoma and atrophic endometrium of postmenopausal women. MATERIALS AND METHODS Ninety-eight postmenopausal women were included in this study and divided into three groups related to histopathologic diagnosis: Group A--endometrial adenocarcinoma (n = 40), Group B--endometrial polyp (n = 38), and Group C--endometrial atrophy (n = 20). The length of this study was from 1990 to 2004. The endometrial samples were collected from hysteroscopic biopsy or surgery then processed for histopathologic routine. One thousand cells of each histological section were evaluated for immunohistochemical analysis using p53 antibodies. The ANOVA test was performed for the statistical analysis. RESULTS The expression of p53 in adenocarcinoma samples was the highest. The expression of polyp was positive when associated to hyperplasia without atypia. All samples of atrophic endometrial were negative. CONCLUSIONS The present data suggested that presence of hyperplasia in the endometrial polyp is factor to increase the expression of p53.

Abstract
UNLABELLED The objective of this review was to address the main indications for palliative surgery in the treatment of ovarian cancer. DESIGN Articles from MEDLINE/PUBMED, EMBASE, and LILACS databases up to May 05, 2012 were included with no bars on foreign languages. The key words used were taken from the Medical Subject Headings and were as follows: ovarian cancer AND palliative surgery, ovarian cancer AND complications, and ovarian cancer AND intestinal obstruction. Subsequently, the references from the original articles were also analyzed. RESULTS Among the complications developing in the course of malignant neoplasia, intestinal obstruction stands out as the main indication for palliative surgery, which may also be indicated for rectovaginal and enterovaginal fistulas, as well as for genital and lower gastrointestinal hemorrhage. CONCLUSION Although incurable, the patients with complications due to ovarian cancer may have an extended survival and an improved quality of life with palliative surgery for the following reasons: a) improvement in the nutritional state after treatment for intestinal obstruction due to the possibility of oral nutrition; and b) improvement in clinical conditions, allowing for palliative chemotherapy.

Abstract
OBJECTIVE To evaluate the action of conjugated equine estrogen, raloxifene and isolated or combined genistein-rich soy extracts on collagen fibers in the bones of oophorectomized rats. MATERIALS AND METHODS Seventy female rats received testosterone propionate (0.1 µg/g) on the 9th day after birth. At 6 months of age, the rats were administered the vehicle (propylene glycol, 0.5 ml/day), and ten of the rats were randomly chosen to comprise the non-oophorectomized control group (GI). The other 60 rats were ovariectomized and randomized into six groups of ten as follows: GII, vehicle; GIII, conjugated equine estrogen (CEE), 50 µg/kg/day; GIV, raloxifene (RAL), 0.75 mg/kg/day; GV, genistein-rich soy extract (GSE), 300 mg/kg/day; GVI, CEE + GSE, 50 µg/kg/day + 300 mg/kg/day; and GVII, CEE + RAL, 50 µg/kg/day + 0.75 mg/kg/day. Three months after surgery, the drugs were administered for 60 consecutive days. All rats were euthanized, and their left tibiae were removed for histological routine. The histological sections were stained with hematoxylin-eosin, and picrosirius for evaluating bone microarchitecture. Types I and II collagen fibers were analyzed by immunofluorescence. Data analysis was carried out with ANOVA and Tukey's test. RESULTS Collagen reduction was significant in the GIII animals when compared to the other groups (p < 0.05). There was no significant difference in the thickness of collagen fibers among the groups. There was a greater quantity of type III collagen in GVI than in the other groups. CONCLUSION Our data indicate that conjugated equine estrogen improves bone quality because it increases the quantity of type I collagen while reducing the quantity of thin collagen fibers. In addition, the combination of CEE and raloxifene or genistein-rich soy extract is not as efficient as CEE itself to improve bone quality.

Abstract
Appropriate decision-making relies on the ability to shift between different behavioral strategies according to the context in which decisions are made. A cohort of subjects exposed to prolonged stress, and respective gender- and age-matched controls, performed an instrumental behavioral task to assess their decision-making strategies. The stressed cohort was reevaluated after a 6-week stress-free period. The behavioral analysis was complemented by a functional magnetic resonance imaging (fMRI) study to detect the patterns of activation in corticostriatal networks ruling goal-directed and habitual actions. Using structural MRI, the volumes of the main cortical and subcortical regions implicated in instrumental behavior were determined. Here we show that chronic stress biases decision-making strategies in humans toward habits, as choices of stressed subjects become insensitive to changes in outcome value. Using functional imaging techniques, we demonstrate that prolonged exposure to stress in humans causes an imbalanced activation of the networks that govern decision processes, shifting activation from the associative to the sensorimotor circuits. These functional changes are paralleled by atrophy of the medial prefrontal cortex and the caudate, and by an increase in the volume of the putamina. Importantly, a longitudinal assessment of the stressed individuals showed that both the structural and functional changes triggered by stress are reversible and that decisions become again goal-directed.

Abstract
AIM To identify aspects of health in postmenopausal Brazilian women using a health-related educational program provided by a multidisciplinary team as part of the primary care approach for early and late postmenopausal symptoms. DESIGN A prospective cohort was formed with 69 postmenopausal women; they were divided into groups corresponding to early (n = 32) and late postmenopause (n = 37) through gynecological and clinical evaluations. We administered the Kuppermann-Blatt Menopausal Index and the Women's Health Questionnaire before and after health education instructions. RESULTS The average age for the onset of menopause was 47.9 years (n = 69). Fifty women (72.5%) in this study had completed their primary education, 78.3% (n = 54) performed manual labor, and 60.9% (n = 42) showed concomitant chronic illnesses. After attending a series of health-related presentations, the mean weight of the women was reduced by 3.54% in early postmenopausal women (p < 0.001) and by 2.06% in the late postmenopausal group (p < 0.001). The mean abdominal circumference was reduced by 1.75% (p < 0.001) in the early postmenopausal group. In addition, the total score in the Kuppermann-Blatt Menopausal Index decreased by 34.38% in the early and by 33.33% in the late postmenopausal groups. According to the Women's Health Questionnaire, there was a decrease in the domain Depressive mood by 0.839 to 0.700 (p < 0.001) in the early and by 0.814 to 0.648 (p < 0.001) in the late postmenopausal groups. CONCLUSION Regardless of improving menopausal symptoms and anthropometric parameters, the effects of the multidisciplinary team activities in early postmenopausal women may be similar to those in late postmenopausal women.

Abstract
BACKGROUND Women with a family history of breast cancer who develop this disease are confronted with important situations regarding the increased risk for development of a second cancer in the contralateral breast. Prophylactic contralateral mastectomy (PCM) reduces by approximately 95% the risk for contralateral breast cancer. In spite of an increase in indications for PCM, the technical difficulties are many regarding the accomplishment of these procedures. The aim of this study is to describe the technique of mastectomy with preservation of the nipple-areola complex and a small incision, reducing surgical difficulties and complications attributed to this technique, thus allowing better aesthetic results in breast reconstruction. METHODS Forty-six patients with indications for PCM (28 bilateral) were submitted to minimally invasive mastectomy from March 2005 to November 2007. A small incision in the superior pole of the areola, sufficient to pass a liposuction 4 mm cannula is made. With the help of this cannula, detachment of the skin from the gland tissue is performed. Then a 3.5 to 4.5-cm long incision in the inframammary fold is made. Glandular detachment is completed using cautery in the subglandular portion and scissors in the upper breast portion cutting the restraints left by the cannula. The mammary gland tissue is removed through this incision. RESULTS Seventy-four breasts were operated on. The resected breast mass ranged from 285 g to 475 g. All 43 patients were reconstructed with prostheses. There was no necrosis of the nipple-areola complex or of the skin. CONCLUSIONS This technique is an option for cases of patients with indications for PCM.

Abstract
OBJECTIVE To evaluate thromboelastographic parameters and fibrinogen levels in women treated with transdermal 17beta estradiol. METHODS 29 menopausal women with a history of venous thromboembolic disease were included. Nine patients composed the treatment (HT) group and 20 the control group. Coagulation was assessed by thromboelastography in samples of whole blood and platelet-poor plasma (PPP). The following thromboelastographic variables were measured: time for initial coagulation (R), blood clotting speed (K and the alpha angle), clot tensile strength (MA and G), global index of coagulation (CI) and fibrinolysis (LY30) and fibrinogen levels. RESULTS There were no differences in the other parameters comparing both groups. Fibrinogen levels showed a 13.77 +/- 19.94% reduction in the HT group and a 5.51 +/- 8.09% increase in the control group after 6 months. CONCLUSIONS Our data suggested that transdermal estrogen may not increase blood coagulability, but that it reduces fibrinogen levels in HT women.

Abstract
OBJECTIVE To determine the effectiveness of the combination of mitomycin C, bleomycin and methotrexate as a neoadjuvant treatment in preparation for surgical treatment of cervical cancer. METHODS AND MATERIALS Twenty-seven patients with carcinoma of the uterine cervix (stages exophytic IB2 and IIB-IIIB) who had not previously undergone any treatment received mitomycin C, bleomycin and methotrexate in five sessions, once every four weeks. RESULTS The objective response rate was approximately 81%, including 16 complete responses and six partial responses. Significant toxic effects were not observed. Responsive patients underwent surgery and remained without evidence of disease for the next 20 years. Unresponsive patients did not fare well and passed away within five years after treatment. CONCLUSION Our data suggest that this strategy may be effective for advanced cases, enabling patients to receive surgical treatment.

Abstract
Impatiens walleriana, busy lizzy or balsam (local names in Brazil maria-sem-vergonha or beijo-de-frade), is an African member of the Balsaminaceae that has long ago been introduced and established in Brazil. It is now widely cultivated commercially as a potted plant and a popular garden plant (3). It also is a common weed along the coast and is particularly troublesome in some banana plantation areas. There are only two records of fungal pathogens attacking this plant in Brazil: Cercospora fukushiana (leaf spot) and Oidiopsis haplophylli (powdery mildew). In January 2009, a population of diseased plants of I. walleriana was found in a private garden in the city of Rio de Janeiro, Brazil. Plants had rotted and girdled stem bases, leading to a collapse of stems Necrotic areas were covered with fans of white mycelium as well as abundant spherical sclerotia. The fungus was isolated in pure culture by direct aseptic transfer of mycelial fragments and sclerotia to potato dextrose agar (PDA) plates. Colonies were white, cottony, often forming fans, primary hyphae 3.0 to 6.0 μm in diameter, and bearing clamp connections; sclerotia formed after 7 days, initially white becoming dark brown with age, and 0.8 to 1.85 mm in diameter. These are typical features of Sclerotium rolfsii. A specimen was deposited in the local herbarium (Herbarium VIC) under Accession No. VIC 30732. Koch's postulates were performed by inoculating three healthy potted I. walleriana plants (10 × 40 cm high) with approximately 100 freshly collected sclerotia placed in close vicinity with the stem bases. Noninoculated plants kept in a separate pot served as controls. Plants were incubated in a dew chamber for 48 h at 25 ± 2°C. All inoculated plants showed symptoms of stem rot 72 h after inoculation, whereas controls remained healthy. S. rolfsii is a highly polyphagous species that has been recorded to be causing rots (also known as Southern blights) in Brazil on numerous hosts but there are no records of it attacking any members of the Balsaminaceae in Brazil. The only other published records of S. rolfsii on Impatiens spp. are from the United States (Hawaii and Illinois) (2) and the Philippines (1). In South America, there is a single report from Argentina (4) where the disease is regarded as a major threat to the potted plant industry because I. walleriana is one of the most popular potted plants in that country. The potential for losses is also significant for Brazil. To our knowledge, this is the first report of S. rolfsii as a pathogen of I. walleriana in Brazil. Although very damaging to I. walleriana, it is unlikely that this fungus can be used as a natural enemy of this plant species in weed situations because of its wide host range. References: (1) T. O.

Abstract
OBJECTIVE To investigate the association between the CYP17alpha gene polymorphism and hot flushes in postmenopausal women. METHODS Ninety-three non-hysterectomized, postmenopausal women were enrolled in this study. Vasomotor symptoms were assessed at the baseline visit and based on information provided by each participant. The genotypic polymorphism of CYP17alpha gene was analyzed by PCR-RFLP assay using genomic DNA isolated from peripheral blood lymphocytes. RESULTS Thirty-six women reported hot flushes of mild intensity, 25 reported hot flushes of moderate intensity and 32 of severe intensity. There was no significant difference between the severity of hot flushes and the CYP17 genotype or allele frequencies, 0.58 and 0.67 respectively. No association was found between hot flush severity and the CYP17 allele (odds ratio = 1.17, p = 0.61). CONCLUSION The results of this study suggest that the CYP17 MspAI polymorphism was not significantly associated with an increased risk of reporting hot flushes.

Abstract
Endoscopic capsule is a recent medical technology with important clinical benefits but suffering from a practical handicap: long exam annotation times. This paper proposes and compares two approaches (Bayesian and support vector machines) that can be used to segment the gastrointestinal tract into its four major topographic areas, allowing the automatic estimation of the clinically relevant gastric and intestinal sections and corresponding transit times. According to medical specialists, this can reduce exam annotation times by up to 12% (15 min). This automatic tool has been integrated into our CapView annotation software that is currently being used by three medical institutions.

Abstract
OBJECTIVE To evaluate the biochemical and morphological effects in rats subjected to three different dose associations of the protease inhibitors lopinavir and ritonavir administered throughout the entire period of pregnancy. STUDY DESIGN The animals were treated throughout pregnancy with daily oral doses of lopinavir+ritonavir starting at the day one of pregnancy, and were divided into four groups: E1, 13.3+3.3 mg/kg; E2, 39.9+9.9 mg/kg; E3, 119.7+29.9 mg/kg and C, control (drug vehicle, propyleneglycol). The animals were then sacrificed and maternal blood and fetal and maternal organ samples were taken for morphological and biochemical analysis. RESULTS No major changes were identified in the group treated with the lowest dose as compared with the control. In the group E2, we found hepatocytes with signs of atrophy, eosinophilic cytoplasm, picnotic nuclei and vasodilatation. The proximal convoluted tubules of maternal kidneys showed eosinophilic areas and hyperchromatic nuclei, as well as signs of vasodilation. In the group treated with the highest dose (group E3), in the maternal kidneys and livers, the morphological changes were similar to those found in E2, although more prominent. Regarding the fetal organs, the single abnormality observed was some liver vasodilation in the group E3 (highest dose). The treatment with lopinavir+ritonavir caused discrete, yet significant, alterations of aspartate aminotransferase activity, blood urea nitrogen and creatinine plasma levels. CONCLUSIONS Our results showed that the administration of a combination of lopinavir plus ritonavir to pregnant rats can cause morphological as well as functional changes in maternal and fetal liver and kidneys and, in higher than therapeutic doses, might be toxic to those animals.

Abstract
In this report we evaluated the action of conjugated equine estrogens (CEE) on vaginal symptoms, cytology, pH, and flora in late postmenopausal women without any previous hormone therapy. The study was a randomized, double-blind, placebo-controlled trial with 48 late postmenopausal women who received placebo or unopposed CEE (0.625mg/day of CEE orally) during three months of treatment. Vaginal and sexual complaints were evaluated through daily diary cards. We analyzed vaginal changes through cytology and pH measurements. After three months of treatment, 20% of placebo-treated patients and 80% of the CEE-treated patients reported improvement in vaginal dryness and irritation. In the latter group, the vaginal cells and Lactobacillus increased and the vaginal pH decreased, without other changes in sexual complaints. We concluded that estrogen ameliorated the genital tract of late postmenopausal women without any previous hormone therapy.

Abstract
Investigations on the mechanisms capable of influencing heart mitochondrial function constitute a central contribution to the understanding of cardiac bioenergetics. In contrast to the conventional idea that reactive oxygen species (ROS) mostly act as a trigger for oxidative damage of biological structures, in low physiological concentrations they can regulate a variety of important molecular mechanisms, including those related to mitochondrial respiratory function. Among others, moderate physical exercise seems to be an important agent to induce cellular and mitochondrial environmental redox modifications and it is possible that these alterations could mediate cardiac mitochondrial respiration patterns. This brief review summarizes some current knowledge on mitochondrial respiratory pathways and focuses on data provided by studies dealing with exercise and cardiac respiratory mechanisms. It is emphasized the need of further experimental studies that analyze the association between physical exercise, particularly endurance training, and several mechanisms hypothetically related to the improvement of mitochondrial function, such as the overexpression of some important chaperone machinery and the up-regulation of both cellular and mitochondrial antioxidants. The influence of chronic moderate exercise on the functionality of some inner membrane components and on mitochondrial calcium loading capacity remains to be established.

Abstract
OBJECTIVE To evaluate the number of lysosomes in glandular epithelia of the endometrioma capsule and endometrium from patients with or without endometriosis using a histochemical method (acidic phosphate determination) under light microscopy. METHOD We studied 31 selected patients with similar clinical features, except for the occurrence of menorrhagia enhanced in patients with endometriosis. All patients were submitted to video laparoscopic procedures and endometrial biopsies through hysteroscopy during the secretory phase. After surgery, the patients were divided into two groups for hysteroscopic data: GI--without endometriosis (control, n = 16) and GII--with endometriosis (n = 15). In GII, the lysosomes of the endometrioma were also counted (GIIa). RESULTS The GI sample was comprised only of endometrial biopsies. We found that the number of lysosomes in the topic endometrial tissue of patients with endometriosis was significantly larger than the number in endometrioma. Also, there were more lysosomes in the endometrium of patients with endometriosis than in endometrioma-bearing patients. CONCLUSION Our data suggest that variations in the number of lysosomes may underlie the pathogenesis of endometriosis.

Abstract
Acetaminophen (paracetamol) is an analgesic-antipyretic drug virtually devoid of typical anti-inflammatory activity and hence free of some of the side-effects of aspirin and related agents (e.g. gastric erosion and bleeding complications). The worldwide use of paracetamol as a household analgesic, including during pregnancy, prompted us to investigate its potentially deleterious effects in that setting. Pregnant rats were treated with paracetamol (150, 500 or 1,500 mg/kg, once a day by gavage) from the first day up to term pregnancy. In the group treated with the lowest doses, no histological changes were noticed in maternal and fetal livers or kidneys when examined under light or electron microscopy. With the higher doses, however, various dose-dependent effects of paracetamol were observed, namely necrotic areas of the liver seen with light microscope and further confirmed by electron microscopy. The kidneys revealed degeneration and necrotic foci under light microscopy with ultrastructural derangements. Electronmicrographs of the liver revealed hepatocytes bearing translucent bodies as a consequence of a dilated smooth endoplasmic reticulum. There were signs of necrosis both in the hepatocytes (lysis of mitochondria and presence of lipid droplets) and renal tissue (mitochondrial cytolysis in convoluted tubules). Our data point out the fact that both maternal and fetal tissues can be adversely affected by paracetamol.

Abstract
The aim of this study was to evaluate the rat ovarian morphological and function changes after pinealectomy (px). Two months after px, young female Wistar rats were sacrificed and the right ovaries were analysed morphologically and the left ovaries were used for steroid receptor binding experiments. Blood was collected and steroid hormone and melatonin levels were measured using radioimmunoassay kits. Results revealed that in the px group the rat ovaries had an increase in the number of atretic follicles and interstitial cells. These cells showed hyperactivity features on transmission electron microscopy and morphometric analysis (p < 0.05 compared with control and sham groups). Px-group serum showed an increase in estradiol (p < 0.05) and a decrease in progesterone levels (p < 0.05) compared with other groups. Moreover, progesterone receptor expression was lower than control and sham groups (p < 0.05). We postulate that pinealectomy leads to many morphological alterations of rat ovaries that are associated with functional changes in steroidogenesis and a decrease in progesterone receptor expression.

Abstract
Finasteride has been used frequently in the treatment of prostate hyperplasia, but this drug inhibits 5alpha-reductase and for this reason could be useful for the treatment of hirsutism. The aim of this study was to evaluate the clinical and hormonal effects of finasteride on hirsute women with idiopathic hirsutism or polycystic ovary syndrome. Twenty-four women were randomly divided into two groups: those given placebo and those given finasteride 5 mg/day. The treatment period was 6 months. All patients were evaluated before the beginning of treatment (baseline) and after 3 and 6 months of treatment using clinical examination through Ferriman-Gallwey score, blood pressure, cardiac frequency and body mass index. Also, we collected blood for hormonal determination of levels of prolactin, 17alpha-hydroxyprogesterone, follicle stimulating hormone, luteinizing hormone, total and free testosterone, dehydroepiandrosterone sulfate, androstenedione and dihydrotestosterone. Furthermore, all patients were asked about their concerns and satisfaction with the treatment. The results showed that the Ferriman-Gallwey score in the 6th month of finasteride treatment was significantly lower than at baseline and the 3rd month of this drug treatment. The dihydrotestosterone level in the finasteride group was also significantly reduced compared to that in the placebo group. The other hormones did not show any statistical difference during the study. All the patients treated with finasteride perceived a reduction in hirsutism after 6 months. In conclusion, our data suggest that finasteride may be effective for the treatment of the hirsute woman with idiopathic hirsutism or polycystic ovary syndrome.
