Objective: To evaluate the effects of the carmine cochineal-resistant spineless cactus genotypes cv. Orelha de Elefante Mexicana (Opuntia) and Miúda (Nopalea) on the intake and digestibility of nutrients, ingestive behavior, performance, and ultrasound measurements of growing lambs. Methods: Thirty-six male (non-castrated) Santa Inês lambs were used, with an average age of 6 months and an initial average weight of 22.0±2.9 kg. They were distributed in a completely randomized design with 3 treatments (Tifton hay, Nopalea and Opuntia) and 12 replications, using initial weight as a covariate. The experimental period was 86 days, with the first 30 days used for the adaptation of the animals to the facilities, diets and management, and the remaining 56 days used for evaluation and data collection. Results: The intake and apparent digestibility of dry matter (DM), organic matter (OM), crude protein (CP), neutral detergent fiber (NDF), total carbohydrates (TC), non-fibrous carbohydrates (NFC), and total digestible nutrients (TDN) showed a significant difference (p<0.05) as a function of the diets, with the Nopalea treatment (p<0.05) increasing DM intake (g/kg and % body weight [BW]), CP, TDN, and TC digestibility, whereas the Tifton hay diet led to a high (p<0.001) neutral detergent fiber corrected for ash and protein (NDFap) g/d intake, NDFap (BW %) and digestibility of said nutrient. There was no effect of treatments (p>0.05) on feeding time, however, rumination time and total chewing time were higher (p<0.05) for animals fed Tifton hay. The performance of the animals was similar (p>0.05). For the ultrasound measurements, Nopalea promoted an increase in the final loin eye area, compared to Tifton hay. Conclusion: The use of spineless cactus variety Miúda leads to the greater intake and digestibility of nutrients. The evaluated carmine cochineal-resistant spineless cactus genotypes are alternatives for semi-arid regions as they do not negatively affect the performance of growing lambs.

Lopes, Sergio Lucio Pereira De Castro,Costa, Andre Luiz Ferreira,Gamba, Thiago De Oliveira,Flores, Isadora Luana,Cruz, Adriana Dibo,Min, Li Li Korean Academy of Oral and Maxillofacial Radiology 2015 Imaging Science in Dentistry Vol.45 No.1

Purpose: Lateral pterygoid muscle (LPM) plays an important role in jaw movement and has been implicated in Temporomandibular disorders (TMDs). Migraine has been described as a common symptom in patients with TMDs and may be related to muscle hyperactivity. This study aimed to compare LPM volume in individuals with and without migraine, using segmentation of the LPM in magnetic resonance (MR) imaging of the TMJ. Materials and Methods: Twenty patients with migraine and 20 volunteers without migraine underwent a clinical examination of the TMJ, according to the Research Diagnostic Criteria for TMDs. MR imaging was performed and the LPM was segmented using the ITK-SNAP 1.4.1 software, which calculates the volume of each segmented structure in voxels per cubic millimeter. The chi-squared test and the Fisher's exact test were used to relate the TMD variables obtained from the MR images and clinical examinations to the presence of migraine. Logistic binary regression was used to determine the importance of each factor for predicting the presence of a migraine headache. Results: Patients with TMDs and migraine tended to have hypertrophy of the LPM (58.7%). In addition, abnormal mandibular movements (61.2%) and disc displacement (70.0%) were found to be the most common signs in patients with TMDs and migraine. Conclusion: In patients with TMDs and simultaneous migraine, the LPM tends to be hypertrophic. LPM segmentation on MR imaging may be an alternative method to study this muscle in such patients because the hypertrophic LPM is not always palpable.

Background: To investigate the prevalence of and factors associated with performance of annual mammography by women above 40 years of age. Materials and Methods: This cross-sectional retrospective study was conducted at an oncology reference service in Southern Brazil from October 2013 to October 2014 with 525 women aged 40 years or older. Results: The prevalence of annual mammography was 54.1%; annual mammographic screening was performed for women without private medical insurance, who were under hormone replacement therapy and who had used contraception in the past. An association was found between non-performance of breast clinical and self-examination and non-performance of mammographic screening. Conclusions: Use of mammography for breast cancer screening in the public health care setting proved to be accessible; nevertheless, the proportion of screened women was low, and they exhibited poor adherence to the basic measures of care recommended for breast assessment. Thus, control of breast cancer requires implementing actions targeting the population most vulnerable to non-adherence to screening in addition to continuously monitoring and assessing that population to reduce the prevalence of this disease.

Numerical calculation of the wind action on buildings using Eurocode 1 atmospheric boundary layer velocity profiles

Lopes, M.F.P.,Paixao Conde, J.M.,Gomes, M. Gloria,Ferreira, J.G. Techno-Press 2010 Wind and Structures, An International Journal (WAS Vol.13 No.6

When designing structures to the wind action, the variation of the mean wind velocity and turbulence parameters with the height above the ground must be taken into account. This paper presents the numerical simulation results of atmospheric boundary layer (ABL) airflows, in a numerical domain with no obstacles and with a cubic building. The results of the flow characterization, obtained with the FLUENT CFD code were performed using the ${\kappa}-{\varepsilon}$ turbulence model with the MMK modification. The mean velocity and turbulence intensity profiles in the inflow boundary were defined in accordance with the Eurocode 1.4, for different conditions of aerodynamic roughness. The maintenance of the velocity and turbulence characteristics along the domain were evaluated in an empty domain for uniform incident flow and the ABL Eurocode velocity profiles. The pressure coefficients on a cubic building were calculated using these inflow conditions.

Couto Lopes Adalva V.,Teixeira Cleide F.,Vilela Mirella B.R.,de Lima Maria L.L.T. 한국산업안전보건공단 산업안전보건연구원 2024 Safety and health at work Vol.15 No.2

Background This study aimed to analyze the trend of occupational noise-induced hearing loss (ONIHL) in Brazilian workers at a metallurgical plant with a hearing conservation program (HCP), which has been addressed in a previous study. Methods All 152 workers in this time series (20032018) participated in the HCP and used personal protective equipment. All annual audiometry records in the company's software were collected from the electronic database. The trend of ONIHL was analyzed with the joinpoint regression model. The hearing thresholds of ONIHL cases at the end of the series were compared with those found in a national reference study. Results The binaural mean hearing thresholds at 3, 4, and 6 kHz at the end of the series were higher for ages ≥50 years, exposures ≥85 dB (A), time since admission >20 years, and maintenance workers. Significance was found only in the group divided by age. There was an increasing time trend of ONIHL, though with a low percentage variation for the period (AAPC = 3.5%; p = 0.01). Hearing thresholds in this study differed from the reference one. Conclusion Despite the unmet expectation of a stationary trend in the study period, the time pace of ONIHL evolution did not follow what was expected for a population exposed to noise. These findings signal to the scientific community and public authorities that good ONIHL control is possible when HCP is well implemented.

The reverse channel connection appears to have the best combination of desirable features under fire loading: moderate construction cost, ability to develop catenary action and extremely high ductility through deformation of the web channel (Ding and Wang, 2007). This paper presents the results of an experimental investigation of a reverse channel component conducted at the University of Coimbra as part of the European RFCS COMPFIRE Project, the main focus of which is to characterise the behaviour of steel joints that connect steel beams to concrete-filled tubular columns under natural fire loading. A series of tensile and compressive tests at ambient and elevated temperatures was conducted. The purposes of the experimental tests were to characterise the strength, stiffness and ductility of this joint component and to establish a relationship between force,displacement and temperature.

ATP13A2 and Alpha-synuclein: a Metal Taste in Autophagy

Tomás Lopes da Fonseca,Tiago Fleming Outeiro 한국뇌신경과학회 2014 Experimental Neurobiology Vol.23 No.4

Parkinson’s Disease (PD) is a complex and multifactorial disorder of both idiopathic and genetic origin. Thus far, more than 20 geneshave been linked to familial forms of PD. Two of these genes encode for ATP13A2 and alpha-synuclein (asyn), proteins that seemto be members of a common network in both physiological and disease conditions. Thus, two different hypotheses have emergedsupporting a role of ATP13A2 and asyn in metal homeostasis or in autophagy. Interestingly, an appealing theory might combinethese two cellular pathways. Here we review the novel findings in the interaction between these two proteins and debate the excitingroads still ahead.

Epilepsy is a disease characterized by the periodic occurrence of seizures. Seizures can be controlled by antiseizure medications, which can improve the lives of individuals with epilepsy when given proper treatment. Therefore, this study aimed to review the scientific literature on brain neuroplasticity after treatment with antiseizure drugs in different regions of the brain. According to the findings, that several antiseizure, such as lamotrigine, diazepam, levetiracetam, and valproic acid, in addition to controlling seizures, can also act on neuroplasticity in different brain regions. The study of this topic becomes important, as it will help to understand the neuroplastic mechanisms of these drugs, in addition to helping to improve the effectiveness of these drugs in controlling the disease.

Romeiro-Lopes, Tiara Cristina,Dell'Agnolo, Catia Millene,Rocha-Brischiliari, Sheila Cristina,Gravena, Angela Andreia Franca,de Barros Carvalho, Maria Dalva,Pelloso, Sandra Marisa Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.11

This study was conducted to analyze the prevalence of non-performance of mammography, and associated factors, among postmenopausal women. This analytical, exploratory, cross-sectional study, of a domicile population inquiry type, was performed in the municipality of Maringa, Parana, Brazil. A total of 456 women were interviewed, aged 45 to 69 years, who presented with natural menopause and cessation of menstruation for at least twelve months. Statistical associations were found between the non-performance of mammography and schooling of less than seven years, paid employment, sedentary lifestyle, smoking, the non-use of hormone replacement therapy, not having consulted a doctor in the previous year, not having consulted a gynecologist, lacking a family history of breast cancer, not having performed the Papanicolaou test, not having performed clinical breast examination, and not having difficult access to health services. After logistic regression analysis, not performing mammography was associated with reports of a fair or bad health status. The study data revealed factors "responsible" for the non-performance of mammography, and the results should contributing to improvement/enhancement of healthy behaviour of Brazilian women in the post-menopausal phase.
