Chondrosarcoma (CSA) is a significant uncommon tumor and tends to be located in the extremi-ties. When it affects the skull base, can be manifested in several ways. We report a case of a CSA in a 21-year-old male patient who presented with headache and neck stiffness. Radiological evaluation revealed a destructive mass in left temporal fossa with surrounding subarachnoid hemorrhage. The angiography was performed with no vascular anomaly. Biopsy of the mass showed characteristic features of a conventional CSA. To the author’s knowledge this is the first report of a skull base chon-drosarcoma presenting with subarachnoid hemorrhage. This case highlights the rarity of this tumor with regard to unusual clinical presentation.

Purpose: Lower urinary tract symptoms are numerous, but the specific impact of each of these symptoms on the quality of life (QoL) has not been evaluated in community-dwelling men. An assessment of these symptoms and their effects on QoL was the focus of this study. Methods: We performed a cross-sectional study with 373 men aged >50 years from a community setting. Patients completed the International Prostate Symptom Score questionnaire, which includes questions on each of the specific urinary symptoms and a question addressing health-related QoL that are graded from 0 to 5. We used the Pearson correlation test to assess the impact of each symptom on QoL. Results: Nocturia (58.9%) was the most prevalent urinary symptom. The mean score was 0.9±1.4 for incomplete emptying, 1.0±1.5 for frequency, 0.9±1.3 for intermittency, 0.8±1.3 for urgency, 1.0±1.5 for weak stream, 0.5±1.0 for straining, and 2.0±1.6 for nocturia. Nocturia and frequency were the only symptoms associated with poorer QoL, with nocturia showing a stronger association. Conclusions: Nocturia affects 50% of community dwelling men aged >50 years, and is the lower urinary tract symptom with the greatest negative impact on QoL.

Objective: Feed additives that modify rumen fermentation can be used to prevent metabolic disturbances such as acidosis and optimize beef cattle production. The study evaluated the effects of liquid and powdered forms of polyclonal antibody preparation (PAP) against Streptococcus bovis and Fusobacterium necrophorum on rumen fermentation parameters in ruminally cannulated non-lactating dairy cows that were adapted or unadapted to a high concentrate diet. Methods: A double 3×3 Latin square design was used with three PAP treatments (control, powdered, and liquid PAP) and two adaptation protocols (adapted, unadapted; applied to the square). Adapted animals were transitioned for 2 weeks from an all-forage to an 80% concentrate diet, while unadapted animals were switched abruptly. Results: Interactions between sampling time and adaptation were observed; 12 h after feeding, the adapted group had lower ruminal pH and greater total short chain fatty acid concentrations than the unadapted group, while the opposite was observed after 24 h. Acetate:propionate ratio, molar proportion of butyrate and ammonia nitrogen concentration were generally greater in adapted than unadapted cattle up to 36 h after feeding. Adaptation promoted 3.5 times the number of Entodinium protozoa but copy numbers of Streptococcus bovis and Fibrobacter succinogens genes in rumen fluid were not affected. However, neither liquid nor powdered forms of PAP altered rumen acidosis variables in adapted or unadapted animals. Conclusion: Adaptation of cattle to highly fermentable carbohydrate diets promoted a more stable ruminal environment, but PAP was not effective in this study in which no animal experienced acute or sub-acute rumen acidosis.

This research aimed to evaluate the eff ectiveness of hot water (43–53 °C · 5 min −1 ; 47 °C · 2–6 min −1 ), 1-methylcyclopropene(1-MCP) at 50–300 nL L −1 and a combination of hot water (47/49 °C · 5 min −1 ) and phosphite (40% P 2 O 5 + 20% K 2 O; 40%P 2 O 5 + 10% Zn) in anthracnose control and the eff ect on fruit quality [fresh weight loss (FWL—%); pH, total soluble solids(TSS—°Brix), and titratable acidity (TA = % citric acid (CA)] of passion fruit ( Passifl ora edulis f. fl avicarpa ) at the postharveststage. When the fruits were in the stage of 0% dehydration and fully yellow peels, they were disinfested and inoculatedwith Colletotrichum gloeosporioides . They were then subjected to the above mentioned treatments; this was followedby incubation for 120 h. The diameter of the disease lesions was monitored daily. After the incubation, a physico-chemicalanalysis was performed. Hot-water treatment resulted in disease reduction at 47 and 49 °C for 4 and 5 min. The combinationof hot-water treatment at 47 °C (4 or 5 min) and application of the phosphite of K or Zn signifi cantly reduced diseaseseverity in fruits. The 1-MCP treatment reduced anthracnose severity in passion fruit mainly at 200 nL L −1 · 24 h −1 . None ofthe treatments signifi cantly changed the physico-chemical characteristics of the fruit [FWL (2.6–4.1%); pH (3.2–3.5), TSS(8.9–10.9 °Brix), and TA (1.8–2.5% CA)].

In this work, the substitution of environmentally harmful additives in the industrial dyeing process of polyamide-6microfiber-made knitted fabrics (PA-6μFKF) was studied. Using the disperse red 60 (DR60) dye, kinetic adsorption tests onthe PA-6μFKF dyeing were performed by using either β-cyclodextrin (β-CD) additive, commercial leveling agents, orwithout additives. Equilibrium tests were also performed during 25 h. A modelling based on a dye adsorption processcontrolled by an intraparticle diffusion was proposed to represent the sets of kinetic data. Three isotherm models were alsotested for representing the equilibrium data. The kinetic data have evidenced three main dye diffusion zones. Differentadsorption mechanisms on PA-6μFKF surface dyeing was evidenced, being the data well represented by the two-stepLangmuir isotherm. Finally, the best quality on color uniformity was attained using the β-CD additive, revealing a goodalternative for the substitution of environmentally harmful additives in industrial dyeing processes.

Background: Oxidative stress and inflammation are common findings in chronickidney disease (CKD) patients, and they are directly related to the increased risk ofdeveloping cardiovascular disease, which is the major cause of death in these patients,particularly for those undergoing hemodialysis (HD). Strength physical exercise is a newtherapeutic approach to reduce these complications in CKD patients. Following this, thepurpose of this study was to assess the effect of acute intradialytic strength physicalexercise on oxidative stress and inflammatory responses in HD patients. Methods: Sixteen HD patients were studied (11 women; 44.4714.6 years; body massindex 23.374.9 kg/m2; 61.6743.1 months of dialysis) and served as their own controls. Acute (single session) intradialytic physical exercise were performed at 60% of the onerepetitionmaximum test for three sets of 10 repetitions for four exercise categories inboth lower limbs during 30 minutes. Blood samples were collected on two different daysat exactly the same time (30 minutes and 60 minutes after initiating the dialysis—withand without exercise). Antioxidant enzymes activity [superoxide dismutase (SOD),catalase, and glutathione peroxidase], lipid peroxidation marker levels (malondialdehyde),and inflammatory marker levels (high-sensitivity C-reactive protein) weredetermined. Results: SOD plasma levels were significantly reduced after acute physical exercise from244.8740.7 U/mL to 222.4728.9 U/mL (P¼0.03) and, by contrast, increased on the daywithout exercise (218.2726.5 U/mL to 239.4738.6 U/mL, P¼0.02). There was noalteration in plasma catalase, glutathione peroxidase, malondialdehyde, or highsensitivityC-reactive protein levels in on either day (with or without exercise). Additionally, there was no association between these markers and clinical, anthropometric,or biochemical parameters. Conclusion: These data suggest that acute intradialytic strength physical exercise wasunable to reduce oxidative stress and inflammation, and in addition, it seems to reduceplasma SOD levels, which could exacerbate the oxidative stress in HD patients.

Objectives This study evaluates the bond strength and marginal adaptation of mineral trioxide aggregate (MTA) Repair HP and Biodentine used as apical plugs; MTA was used as reference material for comparison. Materials and Methods A total of 30 single-rooted teeth with standardized, artificially created open apices were randomly divided into 3 groups (n = 10 per group), according to the material used to form 6-mm-thick apical plugs: group 1 (MTA Repair HP); group 2 (Biodentine); and group 3 (white MTA). Subsequently, the specimens were transversely sectioned to obtain 2 (cervical and apical) 2.5-mm-thick slices per root. Epoxy resin replicas were observed under a scanning electron microscope to measure the gap size at the material/dentin interface (the largest and smaller gaps were recorded for each replica). The bond strength of the investigated materials to dentin was determined using the push-out test. The variable bond strengths and gap sizes were evaluated independently at the apical and cervical root dentin slices. Data were analyzed using descriptive and analytic statistics. Results The comparison between the groups regarding the variables' bond strengths and gap sizes showed no statistical difference (p > 0.05) except for a single difference in the smallest gap at the cervical root dentin slice, which was higher in group 3 than in group 1 (p < 0.05). Conclusions The bond strength and marginal adaptation to root canal walls of MTA HP and Biodentine cement were comparable to white MTA.

Sergio Estelita Barros,Bianca Heck,Kelly Chiqueto,Eduardo Ferreira 대한치과교정학회 2023 대한치과교정학회지 Vol.53 No.2

Objective: To evaluate the null hypothesis that there is no difference in a set of clinical predictors of potentially impacted canines between low-risk patients with and without displaced canines. Methods: The normal canine position group consisted of 30 patients with 60 normally erupting canines ranked in sector I (age, 9.30 ± 0.94 years). The displaced canine group comprised 30 patients with 41 potentially impacted canines ranked in sectors II to IV (age, 9.46 ± 0.78 years). Maxillary lateral incisor crown angulation, inclination, rotation, width, height, and shape, as well as palatal depth, arch length, width, and perimeter composed a set of clinical predictors, which were evaluated on digital dental casts. Statistical analyses consisted of group comparisons and variable correlations (p < 0.05). Results: There was a significant association between sex and mesially displaced canines. Unilateral canine displacement was more prevalent than bilateral displacement. The crown of the maxillary lateral incisors was significantly angulated more mesially and rotated mesiolabially in low-risk patients with displaced canines, who also had a shallower palate and shorter anterior dental arch length. Lateral incisor crown angulation and rotation, as well as palatal depth and arch length, were significantly correlated with the canine displacement severity. Conclusions: The null hypothesis was rejected. Maxillary lateral incisor angulation inconsistent with the “ugly duckling” stage as well as a shallow palate and short arch length are clinical predictors that can significantly contribute to the early screening of ectopic canines in low-risk patients.

Diogo de Vasconcelos Macedo, Gabriely Ferreira, Eduardo Hochuli Vieira, Marcelo Silva Monnazzi 대한구강악안면외과학회 2020 대한구강악안면외과학회지 Vol.46 No.3

Benign fibro-osseous lesions occur when normal bone is replaced by cellular fibrous connective tissue and mineralized structures. One rare type of these lesions is the ossifying fibroma (OF). The aim of this study is to report an unusual case of OF in a 57-year-old female. Physical examination showed facial asymmetry without any tenderness, fluctuation, ocular pain, or ophthalmoplegia. Imaging exams revealed a solid mass involving the left maxilla and orbital floor. Surgical resection was performed without any complications or sequelae, and the histopathological results confirmed OF. Although recurrence is rare in this condition, the patient remains under follow-up.

Breastfeeding and its Relationship with Reduction of Breast Cancer: A Review

Franca-Botelho, Aline Do Carmo,Ferreira, Marina Carvalho,Franca, Juliana Luzia,Franca, Eduardo Luzia,Honorio-Franca, Adenilda Cristina Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.11

In this review, we describe the patterns of known immunological components in breast milk and examine the relationship between breastfeeding and reduced risk of breast cancer. The top risk factors for breast cancer are a woman's age and family history, specifically having a first-degree relative with breast cancer. Women that have a history of breastfeeding have been shown to have reduced rates of breast cancer. Although the specific cause has not been elucidated, previous studies have suggested that breastfeeding reduces the risk of breast cancer primarily through two mechanisms: the differentiation of breast tissue and reduction in the lifetime number of ovulatory cycles. In this context, one of the primary components of human milk that is postulated to affect cancer risk is alpha-lactalbumin. Tumour cell death can be induced by HAMLET (a human milk complex of alpha-lactalbumin and oleic acid). HAMLET induces apoptosis only in tumour cells, while normal differentiated cells are resistant to its effects. Therefore, HAMLET may provide safe and effective protection against the development of breast cancer. Mothers should be encouraged to breastfeed their babies because the complex components of human milk secretion make it an ideal food source for babies and clinical evidence has shown that there is a lower risk of breast cancer in women who breastfed their babies.
