1. Evaluation of the Structural Integrity of Layered Double Hydroxides and Mesoporous Silica During the Preparation of Heterostructures
Heterostructures constructed with mesoporous silica and layered double hydroxides are interesting for catalytic and drug delivery applications. Different arrangements between these phases are possible. In this study, we prepared heterostructures by embedding layered double hydroxides phases [M4Al2(OH)12](CO3) (M = Mg2+ or Zn2+) within the MCM41 mesoporous si

2. Structural Integrity and Cellular Viability of Cryopreserved Allograft Heart Valves in Right Ventricular Outflow Tract Reconstruction: Correlation of Histopathological Changes with Donor Characteristics and Preservation Times
Abstract Introduction: Cryopreserved allograft heart valves (CAHV) show longer event-free survival compared to other types of protheses. However, all patients develop early and/or late allograft failure. Negative predictors are clinical, and there is a lack of evidence whether they correspond with the microscopic structure of CAHV. We assessed histopatholog

3. Utilização da lipoproteína de baixa densidade, em diferentes concentrações, em meio diluidor para criopreservação do sêmen ovino
RESUMO A utilização da gema de ovo dificulta a padronização de meios diluidores e apresenta riscos biológicos. Assim, este estudo avaliou diferentes concentrações da lipoproteína de baixa densidade (LDL), em substituição à gema de ovo, para a confecção de diluentes para criopreservação espermática em ovinos. Foram utilizados um diluidor contr

4. Can we use LDL instead of egg yolk in BotuCrio® extender to cryopreserve sperm from the Mangalarga Marchador stallion?
Abstract The objective of this study was to compare the BotuCrio® extender with the Merk - egg yolk and the INRA 82 modified by the inclusion of acetamide, methyl cellulose and trehalose in substitution of glycerol for freezing equine semen. The semen was diluted after centrifugation to obtain 100 x 106 of sperm/ml in: BotuCrio® (control); Merk - egg yolk

5. Desenvolvimento de sistema de baixo custo para monitoramento de integridade estrutural
RESUMO O Monitoramento da Integridade Estrutural (MIE) pode ser utilizado para avaliar as condições de integridade de uma estrutura, ou ainda para verificar modelos de comportamento da mesma. Os atuais sistemas de monitoramento aplicados em grandes estruturas, contam com inúmeros sensores, dos mais variados tipos, que formam redes de comunicação, em alg

6. PICROSIRIUS RED AND MASSON’S TRICHROME STAINING TECHNIQUES AS TOOLS FOR DETECTION OF COLLAGEN FIBERS IN THE SKIN OF DOGS WITH ENDOCRINE DERMATOPATHOLOGIES
Resumo Endocrinopatias caninas como hipotireoidismo e o hiperadrenocortismo causam alterações dermatológicas características. As fibras de colágeno desempenham um papel vital na manutenção da integridade estrutural e também na determinação da função dos tecidos. O objetivo deste estudo foi avaliar as colorações de picrosirius red sob polarizaç

7. The E3 ligase MuRF2 plays a key role in the functional capacity of skeletal muscle fibroblasts
Fibroblasts are a highly heterogeneous population of cells, being found in a large number of different tissues. These cells produce the extracellular matrix, which is essential to preserve structural integrity of connective tissues. Fibroblasts are frequently engaged in migration and remodeling, exerting traction forces in the extracellular matrix, which is

8. Enhancement the Fatigue Life of Floating Breakwater Mooring System Using Tuned Liquid Column Damper
Abstract Safety is a key design criterion for floating structures. A high rate of mooring accidents has been reported over the past decades. Preventing mooring line failure is a key design objective for floating breakwater systems. The mooring system comprises sets of mooring lines anchored to the seabed. These components are exposed to highly cyclic nonline

9. The Dietary Inclusion of Chickpea Seeds (Cicer Arietinum L.) Influences the Thermal Properties of Muscle Proteins, But Not the Texture of Drumstick Muscle in Broiler Chickens
ABSTRACT In this study, the effect of replacement of soybean meal with raw chickpea seeds as a primary protein source in the diet of broiler chicks on physical properties of drumstick muscle (m. gastrocnemius) was examined. One-day-old Ross 308 broilers (n=160) were fed soybean meal (n=80) or raw chickpea seeds (n=80) as a primary protein source for 42 days.

10. Use of the ACP® and BTS extenders for cooling at 15°C white-lipped peccary (Tayassu pecari) semen
RESUMO: Para auxiliar na conservação da espécie e permitir o uso racional do queixada em cativeiro é de grande importância o conhecimento sobre a reprodução da espécie. Objetivou-se avaliar o efeito dos diluidores de sêmen ACP-103®, ACP-116® e BTS na viabilidade espermática durante a refrigeração do sêmen do Tayassu pecari. Foram refrigerados

11. Gut: Key Element on Immune System Regulation
Abstract The gut is the main organ that mediates the contact between antigens with our organism, controlling the immune response against environmental factors, such as microbiota and food. Innate lymphoid cells participate in the gut-associated lymphoid tissue (GALT) maturation during the prenatal and early postnatal periods. After birth, breast milk provide
