Abstract
BACKGROUND The incidence of nonmelanoma skin cancer (NMSC) exceeds the incidence of all other types of cancers combined. Cumulative sun exposure and intermittent sun exposure are known risk factors for the development of NMSC. Because obesity has been shown to decrease the risk of NMSC incidence, this study investigated whether the risk of NMSC with sun exposure was consistent across different levels of body size. METHODS Body size was assessed with the body mass index (BMI) and the waist-to-hip ratio (WHR). Sun exposure was assessed in watts and langleys and by the amount of time spent outdoors per day in the summer during a person's 30s. RESULTS Among 71,645 postmenopausal women eligible for inclusion in this study, 13,351 participants (18.6%) developed NMSC. A BMI ≥ 25 kg/m2 or a WHR ≥ 0.80 was associated with lower NMSC hazard rates (hazard ratio for BMI, 0.78; hazard ratio for WHR, 0.89); however, the association between higher levels of sun exposure and a higher risk of NMSC was more apparent among women with a BMI ≥ 25 kg/m2 or a WHR ≥ 0.80 in comparison with those of a normal weight (P for interaction for BMI < .001; P for interaction for WHR = .022). CONCLUSIONS Although most studies have considered sun exposure as a covariate, none have addressed the potential interaction of body size with sun exposure; therefore, the effect size of being overweight or obese may have been overestimated. In comparison to the normal-weight group, those in the overweight group had increasingly higher hazard rates with increasing sun exposure. Further studies are warranted to investigate how increased weight interacts with sun exposure to influence skin cancer pathogenesis.

Abstract
Monolaurin is a natural compound that has been known for its broad antimicrobial activities. We evaluate the antifungal activity of monolaurin against Candida albicans biofilms in vivo using a novel bioluminescent model to longitudinally monitor oral fungal infection. Oral fungal infection in vivo was performed using bioluminescent engineered C. albicans (SKCa23-ActgLUC) biofilms on Balb/c mice. The antifungal activity of monolaurin was determined by comparing three groups of mice (n=5/group): monolaurin, vehicle control, and positive control (nystatin). All mice were immunosuppressed with cortisone acetate and oral topical treatments were applied for 5 d. In vivo imaging system (IVIS) imaging was used to monitor the progression of infection over a 5-d period. Total photon flux and ex vivo microbiological analysis of the excised tongues were used to determine the overall fungal burden. Oral topical treatments of monolaurin have resulted in a significant decrease (p<0.05) in the total photon flux over 4 and 5 d post-infection in comparison to the vehicle control group. Furthermore, monolaurin treated group had a significant decrease in colony formation unit of tongue tissue compared to the vehicle control. Our findings support monolaurin as a promising antifungal compound in vivo, which may translate to its future use in the treatment of oral candidiasis.

Abstract
Colon cancer (CC) is the third most common cancer diagnosed in the United States and the incidence has been rising among young adults. We and others have shown a relationship between the immune infiltrate and prognosis, with improved disease-free survival (DFS) being associated with a higher expression of CD8+ T cells. We hypothesized that a microbial signature might be associated with intratumoral immune cells as well as DFS. We found that the relative abundance of one Operational Taxonomic Unit (OTU), OTU_104, was significantly associated with recurrence even after applying false discovery correction (HR 1.21, CI 1.08 to 1.36). The final multivariable model showed that DFS was influenced by three parameters: N-stage, CD8+ labeling, as well as this OTU_104 belonging to the order Clostridiales. Not only were CD8+ labeling and OTU_104 significant contributors in the final DFS model, but they were also inversely correlated to each other (p=0.022). Interestingly, CD8+ was also significantly associated with the microbiota composition in the tumor: CD8+ T cells was inversely correlated with alpha diversity (p=0.027) and significantly associated with the beta diversity. This study is the first to demonstrate an association among the intratumoral microbiome, CD8+ T cells, and recurrence in CC. An increased relative abundance of a specific OTU_104 was inversely associated with CD8+ T cells and directly associated with CC recurrence. The link between this microbe, CD8+ T cells, and DFS has not been previously shown.

Abstract
Esophageal cancer is a highly aggressive neoplasm. In Brazil, it is the sixth most frequent among men and fifteenth among women. The most common type is squamous cell carcinoma (SCC), responsible for 96% of cases. Twenty-eight specimens of Esophael squamous cell carcinoma (ESCC) were obtained by surgery procedures.The tissues were fixed in formalin and embedded in paraffin. In each case, all available hematoxylin and eosin stained sections were examined and a representative block was selected. The ages of these patients ranged from 40 to 93 years, with a mean age of 60 years. Results: The histological grade of tumors was 4 well-differentiated, 19 moderately differentiated and 5 poorly differentiated. Expression of Cox-2 and VEGF in ESCC was demonstrated in 23 (82,14%) and 13 (44,43%) cases, respectively. Adjacent normal mucosa was positive in 11 (39,29%) samples and 9 (32,15%) samples for Cox-2 and VEGF, respectively. No relationship between the expression of Cox-2 and VEGF with the clinicopathological parameters, including gender, age, surgical margin, lymph node status and tumor differentiation. The median follow-up period was 60 months. Survival analysis of patients with ESCC showed no relationship with the expression of Cox-2 and VEGF. Conclusion: VEGF and Cox-2 are expressed in ESCC. Cox-2, VEGF, play a significant role in the origin and development of ESCC and the inhibitors of these proteins could prove to be an important therapeutic tool in the control of this disease.

Abstract
Twenty-eight specimens of Esophael squamous cell carcinoma (ESCC) were obtained by surgery procedures.The
tissues were fixed in formalin and embedded in paraffin. In each case, all available hematoxylin and eosin stained
sections were examined and a representative block was selected. The ages of these patients ranged from 40 to 93
years, with a mean age of 60 years. Results. The histological grade of tumors was 4 well-differentiated, 19 moderately
differentiated and 5 poorly differentiated. Expression of Hsp27 and Hsp70 in ESCC was demonstrated in 23 (82,14%)
and 26 (92,86%) cases, respectively. Adjacent normal mucosa was positive in 11 (39,29%) samples and 9 (32,15%)
samples for Hsp27 and Hsp70, respectively. No relationship between the expression of Hsp27 and Hsp70 with the
clinicopathological parameters, including gender, age, surgical margin, lymph node status and tumor differentiation.
The median follow-up period was 60 months. Survival analysis of patients with ESCC showed no relationship with
the expression of Hsp27 and Hsp70. Conclusion. Taken together, our results demonstrate that Hsp27 and Hsp70 are
expressed in ESCC tissues, but they are not good prognostic factor for patients with ESCC.

Abstract
Oral candidiasis (OC) is an opportunistic fungal infection with high prevalence among immunocompromised patients. Candida albicans is the most common fungal pathogen responsible for OC, often manifested in denture stomatitis and oral thrush. Virulence factors, such as biofilms formation and secretion of proteolytic enzymes, are key components in the pathogenicity of C. albicans. Given the limited number of available antifungal therapies and the increase in antifungal resistance, demand the search for new safe and effective antifungal treatments. Lichochalcone-A is a polyphenol natural compound, known for its broad protective activities, as an antimicrobial agent. In this study, we investigated the antifungal activity of lichochalcone-A against C. albicans biofilms both in vitro and in vivo. Lichochalcone-A (625 μM; equivalent to 10x MIC) significantly reduced C. albicans (MYA 2876) biofilm growth compared to the vehicle control group (1% ethanol), as indicated by the reduction in the colony formation unit (CFU)/ml/g of biofilm dry weight. Furthermore, proteolytic enzymatic activities of proteinases and phospholipases, secreted by C. albicans were significantly decreased in the lichochalcone-A treated biofilms. In vivo model utilized longitudinal imaging of OC fungal load using a bioluminescent-engineered C. albicans (SKCa23-ActgLUC) and coelenterazine substrate. Mice treated with lichochalcone-A topical treatments exhibited a significant reduction in total photon flux over 4 and 5 days post-infection. Similarly, ex vivo analysis of tongue samples, showed a significant decrease in CFU/ml/mg in tongue tissue sample of lichochalcone-A treated group, which suggest the potential of lichochalcone-A as a novel antifungal agent for future clinical use.

Abstract
STUDY OBJECTIVE The adolescent brain may be uniquely affected by acute sleep deprivation (ASD) and chronic sleep restriction (CSR), but direct evidence is lacking. We used electron microscopy to examine how ASD and CSR affect pyramidal neurons in the frontal cortex of adolescent mice, focusing on mitochondria, endosomes, and lysosomes that together perform most basic cellular functions, from nutrient intake to prevention of cellular stress. METHODS Adolescent (1-mo-old) mice slept (S) or were sleep deprived (ASD, with novel objects and running wheels) during the first 6-8 h of the light period, chronically sleep restricted (CSR) for > 4 days (using novel objects, running wheels, social interaction, forced locomotion, caffeinated water), or allowed to recover sleep (RS) for ∼32 h after CSR. Ultrastructural analysis of 350 pyramidal neurons was performed (S = 82; ASD = 86; CSR = 103; RS = 79; 4 to 5 mice/group). RESULTS Several ultrastructural parameters differed in S versus ASD, S versus CSR, CSR versus RS, and S versus RS, although the different methods used to enforce wake may have contributed to some of the differences between short and long sleep loss. Differences included larger cytoplasmic area occupied by mitochondria in CSR versus S, and higher number of secondary lysosomes in CSR versus S and RS. We also found that sleep loss may unmask interindividual differences not obvious during baseline sleep. Moreover, using a combination of 11 ultrastructural parameters, we could predict in up to 80% of cases whether sleep or wake occurred at the single cell level. CONCLUSIONS Ultrastructural analysis may be a powerful tool to identify which cellular organelles, and thus which cellular functions, are most affected by sleep and sleep loss.

Abstract
PURPOSE The aim of this study was to evaluate whether sleep restriction (SR) could affect the mechanisms and pathways' essentials for cancer cells in tongue cancer induced by 4-nitroquinoline 1-oxide in Wistar rats. METHODS The animals were distributed into 4 groups of 5 animals each treated with 50 ppm 4 NQO solution through their drinking water for 4 and 12 weeks. The animals were submitted to sleep restriction for 21 days using the modified multiple platform method, which consisted of placing 5 rats in a cage (41 × 34 × 16 cm) containing 10 circular platforms (3.5 cm in diameter) with water 1 cm below the upper surface. The investigations were conducted using immunohistochemistry of p53, Bax and Bcl-2 proteins related to apoptosis and its pathways. RESULTS Although no histopathologic abnormalities were induced in the epithelium after 4 weeks of carcinogen exposure in all groups, in 12 weeks were observed pre-neoplastic lesions. Data analysis revealed statistically significant differences (P < 0.05) in 4 weeks group for p53, and for bcl-2. Following 12 weeks of 4NQO administration, we found significant differences between SR and control groups in p53, bax, and bcl-2 immunoexpression. CONCLUSION Our results reveal that sleep restriction exerted alterations in proteins associated with proliferation and apoptosis in carcinogenesis.

Abstract
Oral cancer is a serious problem growing in incidence in many parts of the world; it is considered the sixth most common cancer and despite sophisticated surgical and radiotherapeutic modalities, oral squamous cell carcinoma, which represents 90% of oral cancers, is characterized by poor prognosis and a low survival rate. The Epidermal growth factor receptor family of receptor tyrosine kinases (RTK) comprises of four distinct receptors: the EGFR (also known as ErbB-1/HER1), ErbB-2 (neu, HER2), ErbB-3 (HER3) and ErbB-4 (HER4). Several studies have been published on the role of EGFR in the pathogenesis of oral carcinoma. The aim of the present review is to describe the role of EGFR pathway in oral cancer with special focus on its role during the carcinogenesis process as a result of therapeutic approaches of EGFR in oral cancer. The EGFR is a 170-kDa cell-surface protein involved in many biological processes, such as proliferation, migration, DNA synthesis and adhesion. Overexpression of EGFR results in a poor prognosis in oral cancer and its activation is associated with the malignant phenotype, inhibition of apoptosis and increased metastatic potential. EGFR variations and mutations have been correlated with tumor formation, and possibly alter the therapeutic efficacy of EGFR inhibitors.

Abstract
Background: The aim of this study was to evaluate whether paradoxical sleep deprivation could affects the mechanisms and pathways essentials for cancer cells in tongue cancer induced by 4-nitroquinole 1-oxide in Wistar rats. Materials and Methods: For this purpose, the animals were distributed into 4 groups of 5 animals each treated with 50 ppm 4 nitroquinoline 1 oxide (4 NQO) solution through their drinking water for 4 and 12 weeks. The animals were submitted to paradoxical sleep deprivation (PSD) for 72 h using the modified multiple platform method, which consisted of placing 5 mice in a cage (41 × 34 × 16 cm) containing 10 circular platforms (3.5 cm in diameter) with water 1 cm below the upper surface. The investigations were conducted using immunohistochemistry of p53, Bax and Bcl-2 proteins related to apoptosis and its pathways. Statistical analysis was performed by Kruskal-Wallis non-parametric test followed by the Dunn's test using SPSS software pack (version 1.0). P value < 0.05 was considered for statistic significance. Results: Although no histopathological abnormalities were induced in the epithelium after 4 weeks of carcinogen exposure in all groups, in 12 weeks were observed pre-neoplasic lesions. Data analysis revealed statistically significant differences (P < 0.05) in 4 weeks group for p53 and for bcl-2 and for all immunomarkers after 12 weeks of 4NQO administration. Conclusion: Our results reveal that sleep deprivation exerted alterations in proteins associated with proliferation and apoptosis in carcinogenesis.

Abstract
BACKGROUND Mucopolysaccharidosis type I (MPS I) is caused by a deficiency of alfa-iduronidase (IDUA), which leads to intralysosomal accumulation of glysosaminoglycans. Evidences point secondary events like oxidative stress on lysosomal storage diseases including MPS I. Patients with MPS I present a wide range of oral clinical manifestations, including tongue hypertrophy, hypertrophyc alveolar process, and carious teeth. However, the mechanisms by which these alterations occur are still not fully understood. The aim of this study was to analyze the proliferative activity as well as apoptosis in tongue mucosa cells from murine model of MPS I. MATERIALS AND METHODS Protein expression of apoptotic markers such as p53, bcl-2 and bax were evaluated in this setting. Ki-67 was used as a proliferative marker. All analyses were made by immunohistochemistry in tongue cells. Statistical analysis was perfomed by Kruskal-Wallis non-parametric test followed by the Dunn's test. P < 0.05 was considered for statistic significance. RESULTS Histopathological analysis revealed no remarkable differences in tongue mucosa on MPS I mice when compared to control. By contrast, our results demonstrated that bcl-2 immunoexpression was decreased in mice tongue mucosa cells of MPS I mice. p53, bax and ki-67 immunoexpresssion did not show significant differences among controls and MPS I mice. CONCLUSION Taken together, our results suggest that IDUA deficiency, which characterizes MPS I, may induce apoptosis in mice tongue cells as a result of bcl-2 down regulation.

Abstract
Oral cancer is a common neoplasm worldwide. Its incidence and mortality have also increased over the past decades. It is characterized by poor prognosis and a low survival rate despite sophisticated surgical and radiotherapeutic modalities. Metastasis of oral cancer is a complex process involving detachment of cells from tumor tissue, regulation of cell motility and invasion, proliferation and evasion through the lymphatic system or blood vessels. In this review, we will focus on the current knowledge in metastasis from oral cancer regarding facts, such as incidence; stage, histopathology and grade of primary tumor; clinical manifestations; diagnosis; and treatment. Certainly, such information will contribute to the understanding of oral cancer pathogenesis.

Abstract
Skin performs a host of primordial functions that keep the body alive. Morphine is a drug with immunosuppressant properties whose chronic use may lead to increased infection and delayed wound healing. Sleep is a fundamental biological phenomenon that promotes the integrity of several bodily functions. Sleep deprivation adversely affects several systems, particularly the immune system. The aim of this study was to perform an immunohistochemical evaluation on the expression of inducible nitric oxide synthase and cyclooxygenase-2 in skin of sleep-deprived mice and mice chronically treated with morphine. Adult hairless male mice were distributed into the following groups: Control, morphine, sleep-deprived, and morphine + SD. Morphine (10 mg/kg, subcutaneous) was injected every 12 h for 9 days. Morphine induced immunoexpression of cyclooxygenase-2 and nitric oxide synthase. Sleep deprivation did not modulate outcomes induced by morphine. Morphine, not sleep loss, induces cyclooxygenase-2 and nitric oxide synthase immunoexpression in the skin of hairless mice.

Abstract
The Glutatione-S-transferases (GSTs) comprise a family of enzymes closely associated with the cell detoxification of xenobiotics. GSTs exist as homo- or heterodimers and have been grouped into at least seven distinct classes. The main function of GSTs is to catalyze the conjugation of reduced glutathione (GSH) to an electrophilic site of a broad range of potentially toxic and carcinogenic compounds, thereby making such compounds less dangerous and enabling their ready-excretion. Placental GST, known as GST-P 7-7, is the main isoform found in normal placental tissue and comprises 67% of the total GST concentration in this tissue. During development, GST-P 7-7 decreases in concentration and is absent in adult tissues. Interestingly, GST-P 7-7 expression has been detected in adult tissues after exposure to carcinogenic agents in several experimental test systems, being considered a reliable biomarker of exposure and susceptibility in early phases of carcinogenesis. In this article, we review a series of studies involving GST-P 7-7 expression as a suitable tool for understanding cancer pathogenesis, especially cancer risk.

Abstract
Oral cancer is a common neoplasm worldwide. The incidence and mortality have also increased in recent decades. It is characterized by poor prognosis and a low survival rate despite sophisticated surgical and radiotherapeutic modalities. The WNTs comprise a large family of highly conserved growth factors associated with a number of functions. In this review, we focus largely on the canonical pathway, revealing the recent findings, in oral cancer research, thereby raising our understanding of the mechanisms of this crucial signaling in several cellular activities.

Abstract
BACKGROUND This study assessed the genotoxic and cytotoxic potential of three different glass ionomer cements used in Orthodontics (Vidrion C, OptiBand, and Band-Lok). MATERIALS AND METHODS The tested cements were exposed in vitro to mouse fibroblast cells for 1 h at 37°C. The genotoxicity and cytotoxicity were evaluated by means of the single cell gel (Comet Assay) and the trypan blue exclusion test, respectively. All data were assessed by the Kruskal-Wallis non-parametric test, followed by Dunn's test. P < 0.05 was considered for statistical significance. RESULTS Significant statistically differences (P < 0.05) in cytotoxicity were observed for both Vidrion C powder and liquid at the tested concentrations, with exception to the group presenting the lowest powder concentration. OptiBand similarly presented induced cellular death at the highest tested concentration for paste A (P < 0.05). Band-Lok paste B was also able to induce cytotoxicity at the highest tested concentration. Regarding the comet assay, Band-Lok paste B and OptiBand paste A resulted in increased DNA injury (P < 0.05). CONCLUSION The obtained results support the thought that some glass ionomer cement components present both genotoxic and cytotoxic effects when in high concentrations. Since DNA damage and cellular death are important events during oncogenesis, this study represents relevant contribution to estimate the real risks induced by these materials upon cellular systems.

Abstract
The goal of this study was to investigate the expression of some metalloendopeptidases in squamous cell carcinomas of the oropharynx as well as its relation to histological differentiation, staging of disease, and prognosis. Paraffin blocks from 21 primary tumors were obtained from archives of the Department of Pathology, Paulista Medical School, Federal University of Sao Paulo, UNIFESP/EPM. Immunohistochemistry was used to detect the expression of EP24.15 and EP24.16 by means of tissue microarrays. Expression of EP24.15 or EP24.16 was not correlated with the stage of disease, histopathological grading or recurrence in squamous cell carcinomas of the oropharynx. In summary, our results support the notion that EP24.15 and EP24.16 are expressed in carcinoma of the oropharynx; however, these do not appear to be suitable biomarkers for histological grading, disease stage or recurrence as depicted by tissue microarrays and immunohistochemistry.
