1. Agro-Industrial Waste Valorization: Transformation of Starch from Mango Kernel into Biocompatible, Thermoresponsive and High Swelling Nanogels
Mango industry processing disposes 40-60% of this fruit as residues, such as peels and kernels. The exploration of bioproducts from these industrial rejects can reduce environmental impact besides of producing high value-added materials. In this scenario, carboxymethyl starch nanoparticles were produced from mango (Mangifera indica L.) kernel starch. These n

2. Human dental pulp stem cell adhesion and detachment in polycaprolactone electrospun scaffolds under direct perfusion
Cell adhesion in three-dimensional scaffolds plays a key role in tissue development. However, stem cell behavior in electrospun scaffolds under perfusion is not fully understood. Thus, an investigation was made on the effect of flow rate and shear stress, adhesion time, and seeding density under direct perfusion in polycaprolactone electrospun scaffolds on h

3. Polypyridyl Ruthenium Complexes: Novel DNA-Intercalating Agents against Human Breast Tumor
This paper describes a new series of four DNA-intercalating agents with promising anticancer activities, based on ruthenium(II) with the planar ligand dpqQX (dpqQX = dipyrido[3,2-a:2',3'-c]quinoxaline[2,3-b]quinoxaline). The complexes identified as trans-[RuCl2(dppb)(dpqQX)], cis-[RuCl2(dppb)(dpqQX)], ct-[RuCl(CO)(dppb)(dpqQX)]PF6 and ct-[RuCl2(PPh3)2(dpqQX)

4. Study of the ureter structure in anencephalic fetuses
Purpose The objective of this paper is to analyze the structure of the ureter in normal and anencephalic human fetuses. Materials and Methods We studied 16 ureters from 8 human fetuses without congenital anomalies aged 16 to 27 weeks post-conception (WPC) and 14 ureters from 7 anencephalic fetuses aged 19 to 33 WPC. The ureters were dissected and embedded

5. Análise morfológica de imagens e classificação de aberrações cromossômicass por meio de lógica fuzzy / Morphological images analysis and chromosomic aberrations classification based on Fuzzy Logic
Este trabalho desenvolve uma metodologia para a automação da análise morfológica de imagens de cromossomos humanos irradiados no reator nuclear IEA-R1 (localizado no Instituto de Pesquisas Energéticas e Nucleares, IPEN, em São Paulo, Brasil) e, portanto, sujeitos a aberrações morfológicas. Esta metodologia se propõe a auxiliar na identificação, c

6. Experimental murine chromoblastomycosis obtained from Fonsecaea pedrosoi isolate cultured for a long periodt
The present study aimed to describe F. pedrosoi propagules capable of causing chronic murine disease. Several changes in F. pedrosoi hyphae were identified in fungal cells cultured for a long period. Optical microscopy found many rounded cells with double-rigid melanin-rich walls. Terminal and intercalary chlamydoconidia were also frequently observed. Analys

7. Adequacy of cytogenetic dosimetry to evaluate partial and total body irradiation / AdequaÃÃo da dosimetria citogenÃtica para avaliaÃÃo de irradiaÃÃo parcial e de corpo inteiro
The majority of human exposures to ionizing radiation involves partial human body irradiation. Thus, the use of cytogenetic dosimetry, when this aspect is not taken into account, can result in dose underestimation to the irradiated subject. In this context, this research studied methodological parameters of biodosimetry, such as cell culture time, time of Co

8. Uma modelagem matemático-computacional do sistema biológico de percepção de movimento e velocidade
Everything that we see is mentally built by the human brains visual system, from the stimuli received by the retinas: the perception of color, shape, depth and motion, the objects and the complete visual scenes. Researches on artificial intelligence, especially applied to robotics, look for emulating this biological function, in order to enable artificial sy

9. Desenvolvimento e avaliação farmacologica de formulações de liberação controlada com anestesicos locais amino-amidas ciclicos : bupivacaina, mepivacaina e ropivacaina / Development and pharmacological evaluation of drug-delivery systems for cyclic amino-amide local anesthetics: bupivacaine, mepivacaine and ropivacaine
Local anesthetics (LA) are among the different classes of pharmacological compounds used to attenuate or to eliminate pain. These drugs, which are able to reversibly block the excitation/transmission of the nerve impulse in axons have a relatively short action and a significant toxicity to the Central Nervous and Cardiovascular systems. In order to prolong t

10. Epimorphin expression in interstitial pneumonia
Epimorphin modulates epithelial morphogenesis in embryonic mouse organs. We previously suggested that epimorphin contributes to repair of bleomycin-induced pulmonary fibrosis in mice via epithelium-mesenchyme interactions. To clarify the role of epimorphin in human lungs, we evaluated epimorphin expression and localization in normal lungs, lungs with nonspec

11. Localizing the cortical region mediating visual awareness of object identity
Presentations of pictures that are too brief to be recognized, or even guessed above chance on a forced-choice test, nonetheless can facilitate the recognition of the same pictures many trials later. This subliminal visual priming was compared for images translated 4.8° either Within or Between quadrants of the visual field. Priming was evident only fo

12. Transient decrease in water diffusion observed in human occipital cortex during visual stimulation
Using MRI, we report the observation of a transient decrease of the apparent diffusion coefficient (ADC) of water in the human brain visual cortex during activation by a black and white 8-Hz-flickering checkerboard. The ADC decrease was small (<1%), but significant and reproducible, and closely followed the time course of the activation paradigm. Based on th
