Abstract
The inflammasome complex is a key part of chronic diseases and acute infections, being responsible for cytokine release and cell death mechanism regulation. The SARS-CoV-2 infection is characterized by a dysregulated cytokine release. In this context, the inflammasome complex analysis within SARS-CoV-2 infection may prove beneficial to understand the disease’s mechanisms. Post-mortem minimally invasive autopsies were performed in patients who died from COVID-19 (n = 24), and lung samples were compared to a patient control group (n = 11) and an Influenza A virus H1N1 subtype group from the 2009 pandemics (n = 10). Histological analysis was performed using hematoxylin-eosin staining. Immunohistochemical (IHC) staining was performed using monoclonal antibodies against targets: ACE2, TLR4, NF-κB, NLRP-3 (or NALP), IL-1β, IL-18, ASC, CASP1, CASP9, GSDMD, NOX4, TNF-α. Data obtained from digital analysis underwent appropriate statistical tests. IHC analysis showed biomarkers that indicate inflammasome activation (ACE2; NF-κB; NOX4; ASC) were significantly increased in the COVID-19 group (p < 0.05 for all) and biomarkers that indicate cell pyroptosis and inflammasome derived cytokines such as IL-18 (p < 0.005) and CASP1 were greatly increased (p < 0.0001) even when compared to the H1N1 group. We propose that the SARS-CoV-2 pathogenesis is connected to the inflammasome complex activation. Further studies are still warranted to elucidate the pathophysiology of the disease.

Abstract
BACKGROUND Tracheal lesions are pathologies derived from the most diverse insults that can result in a fatal outcome. Despite the number of techniques designed for the treatment, a limiting factor is the extent of the extraction. Therefore, strategies with biomaterials can restructure tissues and maintain the organ's functionality, like decellularized Wharton's jelly (WJ) as a scaffold. The aim is to analyze the capacity of tracheal tissue regeneration after the implantation of decellularized WJ in rabbits submitted to a tracheal defect. METHODS An in vivo experimental study was undertaken using twenty rabbits separated into two groups (n = 10). Group 1 submitted to a tracheal defect, group 2 tracheal defect, and implantation of decellularized WJ. The analyses were performed 30 days after surgery through immunohistochemistry. RESULTS Inner tracheal area diameter (p = 0.643) didn't show significance. Collagen type I, III, and Aggrecan highlighted no significant difference between the groups (both collagens with p = 0.445 and the Aggrecan p = 0.4). CONCLUSION The scaffold appears to fit as a heterologous implant and did not trigger reactions such as rejection or extrusion of the material into the recipient. However, these results suggested that although the WJ matrix presents several characteristics as a biomaterial for tissue regeneration, it did not display histopathological benefits in trachea tissue regeneration.

Abstract
Stem cells (SC) and amniotic membrane (AM) are recognized for their beneficial impacts on the healing of cutaneous wounds. Thus, this study evaluated the capacity of tissue repair in a skin lesion rat model. Forty Wistar rats were randomized into four groups: group I - control, with full-thickness lesions on the back, without SC or AM; group II-injected SC; group III - covered by AM; group IV-injected SC and covered by AM. Lesion closure was assessed using contraction rate (Cr). Histochemical and immunohistochemical analyses were performed, and collagen, elastic fibers, fibroblast differentiation factor (TGF-β), collagen remodeling (MMP-8), and the number of myofibroblasts and blood vessels (α-SMA) were evaluated. On the 7th postoperative day, Cr 1st-7th day levels were higher in groups III and IV. However, on the 28th day, Cr 1st-28th day were higher in the control group. Picrosirius staining showed that type I collagen was predominant in all groups; however, the SC + AM group obtained a higher average when compared to the control group. Elastic fiber analysis showed a predominance in groups that received treatment. Groups II and IV showed the lowest expression levels of TGF-β and MMP-8, and α-SMA was significantly lower in group IV. The application of SC and AM accelerated the initial healing phase, probably owing to their anti-inflammatory effect that favored early formation of collagen and elastic fibers.

Abstract
Purpose: This study aimed to evaluate a cell therapy strategy with human neural precursor cells (hNPCs) to treat diabetic retinopathy (DR) in Wistar rats induced to diabetes by injecting streptozotocin. Material and methods: Wharton's Jelly Mesenchymal stem cells (WJ-MSCs) were isolated, expanded, and seeded onto a biopolymer substrate to develop neurospheres and obtain the hNPCs. The animals were divided into three groups; non-diabetic (ND) n = four; diabetic without treatment (DM) n = nine; and diabetic with cell therapy (DM + hNPCs) n = nine. After eight weeks of diabetes induction and DR characteristics installed, intravitreal injection of hNPCs (1 x 106 cel/µL) was performed in the DM + hNPCs group. Optical Coherence Tomography (OCT) and Electroretinography (ERG) evaluations were before and during diabetes and after cell therapy. Four weeks post-treatment, histopathological and immunohistochemistry analyses were performed. Results: The repair of the retinal structures in the treated group (DM + hNPCs) was observed by increased thickness of neuroretinal layers, especially in the ganglion cell and photoreceptor layers, higher ERG oscillatory potentials (OPs) amplitudes, and transplanted hNPCs integration into the Retinal Pigment Epithelium. Conclusions: The results indicate that hNPCs reduced DR progression by a neuroprotective effect and promoted retinal repair, making them potential candidates for regenerating the neuroretinal tissue.

Abstract
BACKGROUND Cytokines and growth factors play key roles during the tissue repair process. We aim to evaluate the effect of perioperative oral of probiotics, on the healing process in skin wound in rats, by histological aspects, and by the expression of TGF-β, and the pro-inflammatory cytokines IL6, IL7, and TNF-α. METHODS 72 adult male Wistar rats were split into two groups control (n = 36) and probiotic group (n = 36). Each group was subdivided into three subgroups with 12 animals each according to euthanasia day: 3rd, 7th, and 10th postoperative(PO) day. RESULTS Wound contraction was faster with the use of probiotics (p = .013). Also fibrosis was significantly higher in the Probiotic group in the 7th PO day (p = .028). In the probiotic group, there was a reduction of TNF-α at 3th PO day (p = .023); and a reduction of IL6 in 7th PO day (p = .030). There was also a reduction of the expression of IL-17 in 3rd PO day (p = .039) and 7rd PO day (P = .024). In contrast, TGF-β was lower in the 10th PO day (p = .031) in the probiotic group as compared to controls, indicating that the increase of the fibrosis caused negative feedback with the TGF-β. CONCLUSION Probiotics are associated with a shorter inflammatory phase by attenuating the expression of cytokines IL-6 and TNF-α and accelerating the reduction of IL-17 and TGF-β, leading to faster and improved cutaneous healing in rats.

Abstract
Colorectal cancer can develop through molecular, chromosomal, and epigenetic cumulative changes that transform the normal intestinal epithelium into the colorectal polyps, called conventional adenomas (CAs) or serrated polyps (SPs), recognized as precursors of invasive colorectal neoplasia. These benign lesions need to explore the morphology, histological diagnosis, and biomarkers profile to accurately characterize lesions with potential for evolution to cancer. This study aimed to correlate the immunohistochemical expression of Parkin and Adenomatous Polyposis Coli (APC; tumor suppressors), Human Apurinic/Apyrimidinic endonuclease 1 (APE1), and B-cell lymphoma-extra-large (Bcl-xL; oncogenic proteins) in sporadic colorectal polyps with clinical, endoscopic, and diagnostic data. Immunohistochemical analysis was performed on tissue microarray samples of 306 polyps. Based on the Allred score, the expressions were graduated in the cytoplasm and nucleus of superficial and cryptic cells. There was higher Parkin nuclear expression (p=0.006 and 0.010) and APC cytoplasmic expression in cryptic cells (p<0.001) in SPs. CAs, APE1 (p<0.001) and Bcl-xL (p<0.001) were more expressed in the nuclei and cytoplasms, respectively. These results are related to the biological role proposed for these proteins in cellular functions. They can contribute to the diagnosis criteria for polyps and improve the knowledge of biomarkers that could predict cancer development.

Abstract
Zika virus (ZIKV) caused global concern due to Brazil's unexpected epidemic, and it was associated with congenital microcephaly and other gestational intercurrences. The study aimed to analyze the placenta morphometric changes of ZIKV-infected pregnant women (ZIKV group; n = 23) compared to placentas of HIV-infected (HIV group; n = 24) and healthy pregnant women (N-control group; n = 22). It also analyzed the relationship between the morphometric results and pathological alterations on conventional microscopy, gestational trimester of infection, and presence of the congenital Zika syndrome (CZS). There was a significant increase in area (p = 0.0172), as well as a higher number of knots (p = 0.0027), sprouts (p < 0.0001), and CD163 +Hofbauer cells (HCs) (p < 0.0001) in the ZIKV group compared to the N-control group, suggesting that villous dysmaturity and HCs hyperplasia could be associated with ZIKV infections. The HIV group had a higher area (p < 0.0001), perimeter (p = 0.0001), sprouts (p < 0.0001), and CD163 + HCs (p < 0.0001) compared to the N-control group, demonstrating that the morphometric abnormalities found in the ZIKV and HIV group are probably similar. However, when ZIKV and HIV groups are compared, it was observed a higher number of sprouts (p = 0.0066) and CD163+ HCs (p < 0.0001) in the first one, suggesting that placental ZIKV congenital changes could be more pronounced.

Abstract
Discarded tissues, like human amniotic membranes and adipose tissue, were investigated for the application of Decellularized Human Amniotic Membrane (DAM) as a viable scaffold for transplantation of Adipose-derived stromal cells (ASCs) in bone regeneration of non-healing calvarial defects in rats. Amniotic membrane was decellularized to provide a scaffold for male Wistar rats ASCs expansion and transplantation. ASCs osteoinduction in vitro promoted the deposition of a mineralized bone-like matrix by ASCs, as calcified globular accretions associated with the cells on the DAM surface and inside the collagenous matrix. Non-healing calvarial defects on male Wistar rats were randomly divided in control without treatment, treatment with four layers of DAM, or four layers of DAM associated with ASCs. After 12 weeks, tissue blocks were examined by micro-computed tomography and histology. DAM promoted osteoconduction by increasing the collagenous matrix on both DAM treatments. DAM with ASCs stimulated bone deposition, demonstrated by a higher percentage of bone volume and trabecular bone number, compared to control. Besides the osteogenic capacity in vitro, ASCs stimulated the healing of calvarial defects with significant DAM graft incorporation concomitant with higher host bone deposition. The enhanced in vivo bone regeneration by undifferentiated ASCs loaded onto DAM confirmed the potential of an easily collected autologous cell source associated with a broadly available collagenous matrix in tissue engineering.

Abstract
OBJECTIVE Temporomandibular disorder (TMD) is a multifactorial condition and the most common cause of orofacial pain, affecting mostly women, which points to a female hormone predilection. Therefore, the aim of this study was to analyze the association between TMD and estrogen receptor alpha 1 expression in disks of patients with TMD and condyle fracture (CFx). STUDY DESIGN Forty specimens (from 27 patients) included n = 8 CFx, n = 21 anterior disk displacement with reduction (ADDwR), and n = 11 anterior disk displacement without reduction (ADDwoR). Age, area, and intensity of immunostaining were statistically compared between CFx, ADDwR, and ADDwoR groups using analysis of variance and Kruskal-Wallis analysis (P < .05). RESULTS No significant difference between CFx, ADDwR, and ADDwoR groups with respect to age and expression of estrogen receptor alpha 1 was observed on immunohistochemical examination. CONCLUSION No association of estrogen receptor alpha 1 expression and age was found in the CFx, ADDwR, and ADDwoR groups.

Abstract
OBJECTIVE Adaptive changes in DHEA and sulfated-DHEA (DHEAS) production from adrenal zona reticularis (ZR) have been observed in normal and pathological conditions. Here we used three different cohorts to assess timing differences in DHEAS blood level changes and characterize the relationship between early blood DHEAS reduction and cell number changes in women ZR. MATERIALS AND METHODS DHEAS plasma samples (n = 463) were analyzed in 166 healthy prepubertal girls before pubarche (<9 years) and 324 serum samples from 268 adult females (31.9-83.8 years) without conditions affecting steroidogenesis. Guided by DHEAS blood levels reduction rate, we selected the age range for ZR cell counting using DHEA/DHEAS and phosphatase and tensin homolog (PTEN), tumor suppressor and cell stress marker, immunostaining, and hematoxylin stained nuclei of 14 post-mortem adrenal glands. RESULTS We confirmed that overweight girls exhibited higher and earlier DHEAS levels and no difference was found compared with the average European and South American girls with a similar body mass index (BMI). Adrenopause onset threshold (AOT) defined as DHEAS blood levels <2040 nmol/L was identified in >35% of the females >40 years old and associated with significantly reduced ZR cell number (based on PTEN and hematoxylin signals). ZR cell loss may in part account for lower DHEA/DHEAS expression, but most cells remain alive with lower DHEA/DHEAS biosynthesis. CONCLUSION The timely relation between significant reduction of blood DHEAS levels and decreased ZR cell number at the beginning of the 40s suggests that adrenopause is an additional burden for a significant number of middle-aged women, and may become an emergent problem associated with further sex steroids reduction during the menopausal transition.

Abstract
Consumption of non-traditional cigarettes has increased considerably worldwide, and they can induce skeletal muscle dysfunction. Physical exercise has been demonstrated to be important for prevention and treatment of smoking-related diseases. Therfore, the aim of this study was to investigate the effects of combined physical exercise (aerobic plus resistance exercise) on muscle histoarchitecture and oxidative stress in the animals exposed chronically to smoke from hand-rolled cornhusk cigarette (HRCC). Male Swiss mice were exposed to ambient air or passively to the smoke of 12 cigarettes over three daily sessions (four cigarettes per session) for 30 consecutive days with or without combined physical training. 48 h after the last training session, total leukocyte count was measured in bronchoalveolar lavage fluid (BALF), and the quadriceps were removed for histological/immunohistochemical analysis and measurement of oxidative stress parameters. The effects of HRCC on the number of leukocytes in BALF, muscle fiber diameter, central nuclei, and nuclear factor kappa B (NF-κB) were reverted after combined physical training. In addition, increased myogenic factor 5, tumor necrosis factor alpha (TNFα), reduced transforming growth factor beta (TGF-β), and nitrate levels were observed after physical training. However, the reduction in superoxide dismutase and glutathione/glutathione oxidized ratio induced by HRCC was not affected by the training program. These results suggest the important changes in the skeletal muscle brought about by HRCC-induced alteration in the muscle redox profile. In addition, combined physical exercise contributes to remodeling without disrupting muscle morphology.

Abstract
Background:
Chronic wounds in patients with Diabetes Mellitus often become incurable due
to prolonged and excessive production of inflammatory cytokines. The use of
probiotics modifies the intestinal microbiota and modulates inflammatory
reactions.
Aim:
To evaluate the influence of perioperative supplementation with probiotics
in the cutaneous healing process in diabetic rats.
Methods:
Forty-six rats were divided into four groups (C3, P3, C10, P10) according to
the treatment (P=probiotic or C=control, both orally administered) and day
of euthanasia, 3rd or 10th postoperative days. All
rats were induced to Diabetes Mellitus 72 h before starting the experiment
with alloxan. Supplementation was initiated five days before the incision
and maintained until euthanasia. Scalpel incision was guided by a 2x2 cm
mold and the wounds were left to heal per second-intention. The wounds were
digitally measured. Collagen densitometry was done with Picrosirius Red
staining. Histological parameters were analyzed by staining by H&E.
Results:
The contraction of the wound was faster in the P10 group which resulted in a
smaller scar area (p=0.011). There was an increase in type I collagen
deposition from the 3rd to the 10th postoperative day
in the probiotic groups (p=0.016), which did not occur in the control group
(p=0.487). The histological analysis showed a better degree of healing in
the P10 group (p=0.005), with fewer polymorphonuclear (p<0.001) and more
neovessels (p=0.001).
Conclusions:
Perioperative supplementation of probiotics stimulates skin wound healing in
diabetic rats, possibly due to attenuation of the inflammatory response and
increased neovascularization and type I collagen deposition.

Abstract
Background: Manipulating intestinal microbiota with probiotics might stimulate skin
response. Understanding all stages of the healing process, as well as the
gut-skin-healing response can improve the skin healing process. Aim: To evaluate the effect of perioperative oral administration of probiotics on
the healing of skin wounds in rats. Methods: Seventy-two Wistar male adult rats were weighed and divided into two groups
with 36 each, one control group (supplemented with oral maltodextrin 250
mg/day) and one probiotic group (supplemented with Lactobacillus
paracasei LPC-37, Bifidobacterium lactis
HN0019, Lactobacillus rhamnosus HN001,
Lactobacillus acidophilus NCFM® at a dose of
250 mg/day), both given orally daily for 15 days. The two groups were
subsequently divided into three subgroups according to the moment of
euthanasia: in the 3rd, 7th and 10th
postoperative days. Results: There were no significant changes in weight in both groups. Wound contraction
was faster in probiotic group when compared to the controls, resulting in
smaller wound area in the 7th postoperative day. As for
histological aspects, the overall H&E score was lower in the probiotic
group. The probiotic group showed increased fibrosis from 3rd to
the 7th postoperative day. The type I collagen production was
higher in the probiotic group at the 10th postoperative day, and
the type III collagen increased in the 7th. Conclusion: The perioperative use of orally administrated probiotic was associated with a
faster reduction of the wound area in rats probably by reducing the
inflammatory phase, accelerating the fibrosis process and the deposition of
collagen.

Abstract
Aim: To develop a monoclonal antibody against dehydroepiandrosterone (DHEA) and miniaturize it, generating a single-chain antibody variable fragment (scFv) against DHEA as an adrenocortical carcinoma (ACC) marker. Material & methods: DHEA conjugated to keyhole limpet hemocyanin was used as an immunogen to obtain anti-DHEA hybridomas. Variable fragments were cloned from hybridoma 5B7 total RNA, and used to detect DHEA in normal adrenal tissue and ACC cells. Results: IgM monoclonal antibody was highly specific, and the recombinant scFv preserved parental antibody characteristics, allowing tissue localization of DHEA. Conclusion: Undefined small lesions are challenges for clinicians and impact clinical adrenocortical tumor management. Generating an anti-DHEA scFv facilitates development of imaging tests for early diagnosis of pediatric ACC.

Abstract
Introduction: Cardio-renal syndrome subtype 4 (CRS4) is a condition of primary chronic
kidney disease that leads to reduction of cardiac function, ventricular
hypertrophy, and risk of cardiovascular events. Objective: Our aim was to
understand the mechanisms involved on the onset of CRS4. Methods: We used the nephrectomy 5/6 (CKD) animal model and compared to control
(SHAM). Serum biomarkers were analyzed at baseline, 4, and 8 weeks. After
euthanasia, histology and immunohistochemistry were performed in the
myocardium. Results: Troponin I (TnI) was increased at 4 weeks (W) and 8W, but nt-proBNP showed no
difference. The greater diameter of cardiomyocytes indicated left
ventricular hypertrophy and the highest levels of TNF-α were found at 4W
declining in 8W while fibrosis was more intense in 8W. Angiotensin
expression showed an increase at 8W. Conclusions: TnI seems to reflect cardiac injury as a consequence of the CKD however
nt-proBNP did not change because it reflects stretching. TNF-α characterized
an inflammatory peak and fibrosis increased over time in a process
connecting heart and kidneys. The angiotensin showed increased activity of
the renin-angiotensin axis and corroborates the hypothesis that the
inflammatory process and its involvement with CRS4. Therefore, this animal
study reinforces the need for renin-angiotensin blockade strategies and the
control of CKD to avoid the development of CRS4.

Abstract
Background Nephroblastoma or Wilms tumor is the most frequent kidney cancer in children and accounts for 98% of kidney tumors in this age group. Despite favorable prognosis, a subgroup of these patients progresses to recurrence and death. The retinoic acid (RA) pathway plays a role in the chemoprevention and treatment of tumors due to its effects on cell differentiation and its antiproliferative, anti-oxidant, and pro-apoptotic activities. Reports describe abnormal cellular retinoic acid-binding protein 2 (CRABP2) expression in neoplasms and its correlation with prognostic factors and clinical and pathological characteristics. The aim of this study was to evaluate the immunohistochemical expression of retinoic acid receptor alpha (RARA) and CRABP2 in paraffin-embedded samples of nephroblastomas via semiquantitative and quantitative analyses and to correlate this expression with prognostic factors. Methods Seventy-seven cases of nephroblastomas were selected from pediatric oncology services. The respective medical records and surgical specimens were reviewed. Three representative tumor samples and one non-tumor renal tissue sample were selected for the preparation of tissue microarrays (TMA). The Allred scoring system was used for semiquantitative immunohistochemical analyses, whereas a morphometric analysis of the stained area was employed for quantitative evaluation. The nonparametric Mann-Whitney test was used for comparisons between two groups, while the nonparametric Kruskal-Wallis test was used to compare three or more groups. Results Immunopositivity for RARA and CRABP2 was observed in both the nucleus and cytoplasm. All histological components of the nephroblastoma (blastema, epithelium, and stroma) were positive for both markers. RARA, based on semiquantitative analyses, and CRABP2, bases on quantitative analyses, exhibited increased immunohistochemical expression in patients with metastasis, with p values of 0.0247 and 0.0128, respectively. These findings were similar to the results of the quantitative analysis of RARA expression, showing greater immunopositivity in tumor samples of patients subjected to pre-surgical chemotherapy. No significant correlation was found with the other variables studied, such as disease stage, anaplasia, risk group, histological type, nodal involvement, and clinical evolution. Conclusions Semiquantitative and quantitative analyses of the markers RARA and CRABP2 indicate their potential as biomarkers for tumor progression and their participation in nephroblastoma tumorigenesis.

Abstract
Objective Features of colorectal cancer such as natural history, molecular, chromosomal, and epigenetic alterations have been well described. However, there is still a lack of accurate prognostic markers, which is evident by the lower overall survival rates of patients with advanced cancer. Although alterations in parkin protein expression have been described in colorectal cancer, the functional significance of this protein remains unknown. The present study aimed to investigate the involvement of parkin expression in colorectal adenocarcinoma development and progression by evaluating the association between its expression, clinicopathological parameters, and expression of known proteins involved in colorectal cancer. Methods Tissue microarrays consisting of 73 tumor and 64 normal tissue samples were generated to examine parkin expression and localization by immunohistochemistry. Results A positive correlation of parkin and APC expression was observed in the superficial, intermediate, and profound regions of all cases (ρ = 0.37; P = 0.001). Parkin expression was also significantly associated with tumors in men (P = 0.049), those of the mucinous subtype (P = 0.028), and of advanced stage (III + IV, P = 0.041). In addition, increased parkin expression was observed in the invasive front tumor region (P = 0.013). More importantly, a positive correlation was found between parkin expression and the overall survival of patients with advanced colorectal cancer (P = 0.019). Multivariate analysis showed that parkin expression was independent of any of the clinicopathological parameters evaluated in relation to patient survival. Conclusions These results suggest that parkin expression status can be used as a potential independent prognostic marker of survival in advanced colorectal cancer.

Abstract
In May 2015, the first episodes of Zika virus infection of the Latin America were confirmed in Brazil, where currently 196 976 cases were reported. The main route of transmission occurs by Aedes mosquitoes, and the most common symptoms are maculopapular rash, fever, conjunctivitis, polyarthralgia, and periarticular edema. However, the infection is asymptomatic in 80% of the cases. The congenital infection is characterized when the transmission to the fetus occurs during pregnancy, but the mechanisms of how the virus infects the placenta remain unclear. Anatomopathological findings were described in first- and third-trimester human placentas; however, the major affected tissue of the baby is the neural. Several clinical situations were listed in these fetuses, such as neurological, ophthalmological, auditory, and articular alterations. The World Health Organization proposed a new congenital syndrome caused by Zika virus. The virus has an important neurotropism and the main manifestation observed in the syndrome is microcephaly, which is usually severe and associated with other neurological injuries. The appearance of sudden rash in pregnant women determines immediate investigation through RT-PCR and serological analysis. Moreover, the prevention consists in using repellents and avoiding endemic areas, considering that the vaccine is still under development.

Abstract
It has been demonstrated that the cytotoxic effect of BJcuL, the lectin isolated from Bothrops jararacussu venom, on human gastric carcinoma is accompanied by the inhibition of extracellular matrix adhesion, cytoskeleton disassembly and apoptosis induction. The present study aimed to evaluate the apoptosis mechanisms triggered by the BJcuL interaction with specific glycans on the surface of HT29 human colon adenocarcinoma cells. The results demonstrated that BJcuL interacts with glycoligands targets on the cell, which were inhibited in the presence of d-galactose. It shows a dose-dependently cytotoxic effect that is inhibited in the presence of d-galactose. A dose-dependent cell aggregation decrease was also observed for the HT29 cells. Analysis of cell proliferation inhibition was assessed by anti-PCNA and demonstrated that lectin diminishes PCNA expression when compared with untreated cells. Differences in apoptotic marker expression estimated by immunohistochemistry revealed that the lectin promotes an increase in TRAIL expression, leading to an increase in the expression of FADD, caspase-8 and Bax. Besides the increased expression of apoptosis-related proteins, our results revealed that the lectin promotes a mitochondrial respiration decrease and a 75% increase in the amount of cytochrome c released. Together these results suggest that the cytotoxicity of BJcuL can sensitize pro-apoptotic proteins in the cytoplasm and mitochondria, leading to the apoptotic cascade.

Abstract
BACKGROUND Myocardial infarction is a public health problem. Functional food is an alternative treatment for cardiovascular diseases. OBJECTIVE The objective was to analyze the functional and anatomopathological post-myocardial-infarction effects of soybean extract (SE) and isoflavone (IF). METHODS Myocardial infarction was induced in adult Wistar rats. After 5 days, an echocardiogram was performed to determine heart rate (HR), ejection fraction (EF), systolic volume (LVESV) and diastolic volume (LVEDV). Animals with ventricular dysfunction (EF<45%) were selected for study. The animals were divided into three groups: control (n=14), SE (n=15) and IF (n=12). The IF group received 120 mg/kg/day isolated IF, and the SE group received 12.52 g/day. After 30 days, a new echocardiogram was performed. A histological exam was carried out to determine the collagen. Activity of biochemical markers [arginase, lactate dehydrogenase (LDH) and malate dehydrogenase] was measured. RESULTS The animals of the control, IF and SE groups showed a reduction in EF after the infarction (P=.432, P=.017 and P=.320, respectively). An increase of LVESV and LVEDV was observed in all groups (P=.009, P=.001 and P=.140; and P=.003, P=.008 and P=.205, respectively). A reduction of HR was found in the SE group (P=.020). There was a greater activity of LDH in the SE group. A smaller quantity of mature collagen was found in the region proximal to the myocardial infarction in the SE group. CONCLUSION A protective effect in the SE group was observed 30 days after the myocardial infarction.

Abstract
OBJECTIVE The objective was to analyze the decellularization process with SDS in glutaraldehyde-preserved bovine pericardium as an anticalcification method in a circulatory sheep model. METHODS The valved tubs were implanted in pulmonary artery position in sheep by 180 days. The animals were divided in two groups of 8 animals: control group--glutaraldehyde-preserved bovine pericardium and the study group--decellularized bovine pericardium with 0,1% SDS and glutaraldehyde-preserved. After explantation the tubs were analized by x-ray macroscopy, hematoxilin-eosin, alizarin-red and Russel-Movatz pentacromic histology. The calcium content was measured by flame atomic absorption spectrometry. RESULTS There was no early mortality, but two animals in each group died during the study. All cusps in the control group were severely calcified and in some points in the conduits, while the decellularized group did not show macroscopic calcification. Data were proved by x-ray and histologycal exams. The matrix was preserved in histologycal analysis in decellularized group, without gross calcification. The wall conduits calcium content was 35,25 ± 42,13 µg/mg in the control group versus 15,75 ± 10,44 µg/mg in the decellularized one: in the cusps was 264,4 ± 126,16 µg/mg in control group versus 94,29 ± 27,05 µg/mg in decellularized group (P = 0,009). CONCLUSION The decellularization with 0.1% SDS was effective as an anticalcification method in bovine pericardial grafts implanted in a sheep circulatory model for 180 days.

Abstract
UNLABELLED Although renal dysfunction is a known risk factor for cardiovascular disease (CVD), there are few experimental studies investigating the cardiovascular consequences of this condition. OBJECTIVE To analyze the impact of the induction of renal dysfunction on biomarkers of cardiovascular risk and on the histology of subepicardial vessels. METHODS This experimental study involved thirty Wistar male rats, which were divided into two groups. One (chronic kidney disease - CKD group) underwent renal ablation, and the other (SHAM group) was submitted to kidney manipulation only. Both groups were followed up for eight weeks. During follow-up, serum levels of urea, phosphorus and TNF-α were measured. Heart tissue was processed for histological analysis. RESULTS The CKD group had increased levels of urea and phosphorus, in comparison with the SHAM group. The levels of TNF-α were increased in the CKD group and undetectable in the SHAM group (p < 0.05). Thickness of the middle layer of the subepicardial vessels of the CKD group was significantly higher than that of the SHAM group (p = 0.011). CONCLUSION Induction of renal dysfunction in rats increased the biomarkers of cardiovascular risk and led to a thickening of the subepicardial vessels when compared with normal controls.

Abstract
INTRODUCTION The cryopreserved homograft is a good valve substitute due attributes like excellent hemodynamics, low incidence of thromboembolic events, infection resistance and good mid-term durability. However, progressive homograft degeneration and fibrocalcification may occur, particularly in the childhood and young adults. Their antigenicity triggers an immunological reaction that plays an important role in their degeneration and failure. The decellularization process was proposed to decrease this antigenicity. By the action of detergents and enzymes, this process removes all cellular components from the homograft matrix, diminishing immunogenicity and probably delaying its degeneration. OBJECTIVE The objective of this experimental and descriptive study is to evaluate the biological and functional behavior of decellularized pulmonary homografts (Decell-H), treated by a sodium dodecil sulfate solution (0.1%), developed in our University (Pontifícia Universidade Católica do Paraná). For the characterization of Decell-H performance, parameters like recellularization, calcification, and echocardiographic data will be analyzed. METHODS Eight juvenile sheep were submitted to the implantation of the Decell-H sutured into orthotopic position, through a left thoracotomy and with cardiopulmonary bypass support. They were followed-up clinically and by periodical echocardiograms until the explantation, which were performed in different time for every two sheep: seven, 30, 90 and 180 postoperative days. For histological analysis we used Hematoxilin-eosin, Movat and Alizarin-Red staining. RESULTS The sheep reached their follow-up period in a good clinical state. There was no valve regurgitation or stenonis by the echocardiogram. The animals submitted to the explantation in 90 and 180 days had a significant somatic growth and these Decell-H(s) had a diameter increase, without central valve insufficiency. Histologically, all homografts preserved their extra-cellular matrix organization and were progressively recellularized, without calcification. CONCLUSION In this experimental model, the Decell-H behaved as an excellent valve substitute.

Abstract
We describe a rare occurrence of congenital peribronchial myofibroblastic tumor of the lung presenting in early fetal life. A female patient in the 24th week of gestation who presented with polyhydramnios was admitted for examination. Ultrasound examination revealed a mass compromising the lungs. Because the intrauterine fetal death was revealed by the ultrasound, delivery was induced. Necropsy revealed a pulmonary lesion compromising the left lower pulmonary lobe together with hepatomegaly. Microscopic analysis of the lung showed a lesion with a storiform arrangement of spindle cells with focal peribronchial distribution. Hepatic architecture was diffusely altered by fibrotic tissue. Immunohistochemical analysis on the pulmonary lesion showed high vimentin positivity in the fusocellular components, pointing to the mesenchymal nature of the lesion. Significant differentiation of smooth muscle tissue, as indicated by high HHF35 positivity, was also observed. Electron microscopy on the pulmonary lesion revealed elongated cells with some cytoplasmatic processes, a finding that is also compatible with mesenchymal differentiation.

Abstract
PURPOSE To study the role of methylene blue as an inhibitor of superoxide production by xanthine oxidase. METHODS Thirty-two Wistar rats were divided into 2 groups of 16 animals: the control group and the experimental group. All were submitted to a laparotomy for the occlusion of the cranial mesenteric artery during 60 minutes. The reperfusion was confirmed by the pulsation of the artery after the release of the temporary ligature and color change of the intestines. In the animals of the control group, 2 ml of saline were injected in the peritoneal cavity and in the animals of the experimental group, 2 ml of methylene blue were injected in the peritoneal cavity. After reperfusion for 4 hours, the animals were then sacrificed. The lungs were excised from all 32 rats. Simultaneously, the small intestine and kidneys were ressected in 20 animals (10 from the control group and 10 from the experimental group). Samples of the organs were taken to evaluate the action of xanthine-oxidase, for histopathology studies and for characterization of the edema. RESULTS In the animals of the experimental group, the inflammatory lesion as well as the edema in the lung was greater than in the control group. The intestinal and renal lesions were similar in both groups, but the lung damage was superior to that observed in the intestines and kidneys. . CONCLUSION Despite similar action of the xanthine oxidase in the control and the experimental group, after intestinal ischemia and reperfusion, the protective effect of methylene blue was observed only in the lungs of the experimental group.

Abstract
Sneddon's syndrome (SS) is characterized by ischemic cerebrovascular episodes and livedo reticularis. It is more common in young women and can also be associated with valvulopathy, a history of spontaneous abortion, renal involvement and vascular dementia. We describe three cases of young women with this disease. The patients had repeated ischemic cerebral episodes, livedo reticularis and thrombocytopenia. CT and MRI showed strokes and cerebral atrophy. Autopsy in one of the patients revealed cerebral infarctions. Anticardiolipin antibodies were detected in two patients. Antiphospholipid antibodies may be found in some patients with ischemic cerebrovascular events and livedo reticularis. SS may thus be associated with antiphospholipid syndrome. We described three new cases of SS and discuss the pathophysiology of this disease.

Abstract
PURPOSE: Experimental evaluation of the abdominal wall healing in reoperations on the same surgical site, by means of macroscopic analysis, histological and breaking strength studies of the surgical scar. METHODS: Twenty-four rats were selected and divided in 3 groups (G1, G2 and G3). A medium longitudinal laparotomy was performed, followed by laparorrhaphy on two synthesis planes, using an interrupted suture technique. The reoperations were performed in the same way, on the same surgical site. On the first day of the study all the 24 rats were operated, on the 30th day the 16 animals belonging to G2 and G3 were reoperated, and finally, on the 60th day, the 8 rats from G3 were operated for the third and last time. After 30 days of the last laparotomy of each group, euthanasia was performed. Complications such as adhesions were evaluated during the resection of surgical site. The breaking strength study was performed next, followed by the microscopical collagen analysis, using for that histological cuts stained with picrosirius. RESULTS: The adhesions were prevalent in G2 and G3 (16% each) when compared to G1. No significant difference was found in the breaking strength study. Statistically significant difference was observed in collagen concentration analysis. It was found higher mature collagen (type I) as well as total collagen concentration in the groups operated more than once (G2 and G3). The highest concentration of mature collagen (p<0,0001) and total collagen (p<0,0021) were found in G3 followed by G2 and G1 (in this sequence). CONCLUSION: The highest mature collagen concentration on the experimental groups, points out the importance of inflammatory activity in the healing process; in the resutures of the abdominal wall the surgical scar maturity is faster acquired than in the primary sutures; in relation to the primary sutures, the resutures of the abdominal wall did not influence in the resistance of the surgical scar.

Abstract
O objetivo deste estudo é relatar um caso de lesão verrucosa cujo diagnóstico foi de nevo melanocítico composto associado à hiperplasia siringofibroadenomatóide. O paciente foi submetido a exérese de lesão cutânea abdominal com diagnóstico clínico de nevo melanocítico de Miesher. A microscopia óptica revelou epiderme hiperplásica e derme com ninhos de células névicas intimamente associados com aglomerados de ductos écrinos e arranjados segundo um padrão siringomatóide. A concomitância de hiperplasia epidérmica e proliferação siringomatóide é definida como siringofibroadenomatose écrina e pode ser devida a fatores de crescimento secretadas pelo estroma alterado.

Abstract
OBJETIVO: Estudar comparativamente a cicatrização e a formação de aderências em baço de ratos submetidos à trauma operatório e corrigidos utilizando octil-2-cianoacrilato (DE) e fio de poliglecaprone 25 (CA). MÉTODO: 30 ratos machos Wistar foram separados em três grupos de 10 animais, anestesiados de acordo com as normas do COBEA, submetidos à laparotomia xifopúbica e com uma tesoura Metzenbaum, foi realizada uma lesão esplênica com 4mm de profundidade, na borda anti-hilar do pólo inferior do baço. No Grupo CA, suturou-se a lesão com pontos contínuos de poliglecaprone 25; no Grupo DE, com octil-2-cianoacrilato e no Grupo CO, não houve sutura. Após 14 dias, os ratos foram submetidos à eutanásia e as aderências anotadas em protocolo próprio. O estudo anatomopatológico foi realizado nas colorações hematoxilina-eosina e Picro-Sirius, sendo do tipo fechado, duplo-cego. RESULTADOS: O Grupo DE apresentou menos aderências e menor reação de cicatrização tipo corpo estranho que o CA. Ambos mostram quantidade semelhante de colágeno jovem e maduro. CONCLUSÕES: O octil-2-cianoacrilato provocou menos aderências macroscópicas que o fio de poliglecaprone corado e não induziu cicatrização com reação de corpo estranho, mostrando-se efetivo no reparo das lesões traumáticas esplênicas, em ratos.

Abstract
Epidemiological data from the Quality Assurance Unit (QAU) of the Cervical Cancer Screening Program of Paraná is discussed. Slides (65,753) reviewed by the QAU, from October 1997 to July 1999, were analyzed. Relations between agreement rate, diagnostic categories, and age groups were tested. The overall agreement rate was 97.04% (kappa +/- 95%, confidence interval = 0.888 +/- 0.003). Low-grade squamous intraepithelial lesion (LSIL) showed its peak prevalence in patients < or = 19 yr (8.3%). High-grade squamous intraepithelial lesion (HSIL) was more common in women between 40 and 49 yr (5.0%). Squamous-cell carcinoma (SCC) was almost exclusively seen in women > or = 40 yr. The lowest agreement rates were seen in adenocarcinoma (54.5%; kappa = 0.667) and LSIL cases (76.3%, kappa = 0.822), and in women < or = 19 yr (95.8%). It was concluded that constant monitoring to assess specific errors allows directed measures. The 10% rescreening model of quality assurance proved to be effective in a low resources setting with a positive overall financial impact.
