1. Transmission electron microscopy of pili annulati
Abstract Background: Little is known about the ultrastructure of pili annulati. Objectives: To examine with transmission electron microscopy affected hairs of a family, whose diagnosis had been confirmed in five individuals with scanning electron microscopy, which showed surface undulations with ‘‘curtain-like’’ folding of the hair cuticula and to

2. Evaluation of Lignins of Trunk and Roots from Citrus sinensis L. Osbeck: A Large Available Brazilian Biomass
Citrus biomass is a source of biobased products and presents extensive chemical diversity. Among the structural macromolecules, lignins have been used in resins, bioplastics, and nanoencapsulation. Brazil has a large source of lignins, which are orange trees removed from groves that need to be renewed. However, the knowledge about these lignins is limited an

4. Determination of Barreling of Aluminum Solid Cylinders During Cold Upsetting Using Genetic Algorithm
ABSTRACT This study presents Genetic Programming models for the formulation of barreling of aluminum solid cylinders during cold upsetting based on experimental results. The maximum and minimum radii of the barreled cylinders having different aspect ratio (d/h= 0.5, 1.0 and 2.0) were measured for various frictional conditions (m=0.1-0.4). The change in radii

5. Entrópio palpebral severo pós cirurgia de correção de ptose
Resumo Paciente de 69 anos evoluiu com entrópio palpebral severo após cirurgia de correção de ptose palpebral pela técnica de reinserção da aponeurose do músculo levantador da pálpebra superior. Realizada reintervenção onde foi diagnosticado uma fixação da aponeurose em uma posição muito inferior e feita uma refixacação no 1/3 superior do ta

6. In silico prediction of the functional and structural consequences of the non-synonymous single nucleotide polymorphism A122V in bovine CXC chemokine receptor type 1
Resumo O presente estudo objetivou avaliar se o polimorfismo causal A122V promove alterações nas propriedades funcionais e estruturais da proteína receptora de quimiocina CXC do tipo 1 (CXCR1) de bovino Bos taurus por análises in silico. Duas sequências de aminoácidos da CXCR1 bovina foram selecionadas a partir do banco de dados UniProtKB/Swiss-Prot:

7. Protein-protein interactions of the nicotinamide/nicotinate mononucleotide adenylyltransferase of Leishmania braziliensis
BACKGROUND Nicotinamide adenine dinucleotide (NAD) plays a central role in energy metabolism and integrates cellular metabolism with signalling and gene expression. NAD biosynthesis depends on the enzyme nicotinamide/nicotinate mononucleotide adenylyltransferase (NMNAT; EC: 2.7.7.1/18), in which converge the de novo and salvage pathways. OBJECTIVE The pu

8. Structural framework of the iron district of Itabira, Iron Quadrangle, Minas Gerais
Abstract The Itabira Iron District, located at the northeastern end of the Iron Quadrangle, still presents some uncertainties regarding the tectonic origin of its macrostructure. The Itabira synclinorium is characterized by a large synformal structure in the NE-SW direction, with anticlines and synclines distributed "en echelon". The analysis of the relation

9. GJB2 c.235delC variant associated with autosomal recessive nonsyndromic hearing loss and auditory neuropathy spectrum disorder
Abstract Autosomal recessive nonsyndromic hearing loss (ARNSHL) is a genetically heterogeneous neurosensory disorder, usually characterized by congenital or prelingual hearing loss. We report a Han Chinese male, born to consanguineous parents, presenting with nonsyndromic sensorineural hearing loss, whose clinical phenotype was also consistent with auditory

10. A smart approach for delivery of aripiprazole via oro-soft palatal mucosal route for improved therapeutic efficacy
Effective management of schizophrenia, acute mania, mixed episodes associated with bipolar disorders, and depression can be managed with aripiprazole moiety. In the present research work an attempt was made to minimize the dose related side effects thus improving the quality life of the patients. A novel biopolymer was isolated from the fruits of Trachysperm

11. Research on the Folding Patterns and Deployment Dynamics of Inflatable Capsule Structures
ABSTRACT: The folding patterns and deployment dynamic characteristics of conical inflatable capsule structures were investigated. A six-fold-line method of packing a conical shell surface was designed. The fold-line layouts and relation formulas of the fold angles were determined. The folded state of the inflatable capsule structure was parametrically modele

12. Application of n-dodecane as an oxygen vector to enhance the activity of fumarase in recombinant Escherichia coli: role of intracellular microenvironment
Abstract The effect of the intracellular microenvironment in the presence of an oxygen vector during expression of a fusion protein in Escherichia coli was studied. Three organic solutions at different concentration were chosen as oxygen vectors for fumarase expression. The addition of n-dodecane did not induce a significant change in the expression of fumar
