Abstract Objective Allergic sensitization is one of the key components for the development of allergies. Polysensitization seems to be related to the persistence and severity of allergic diseases. Furthermore, allergic sensitization has a predictive role in the development of allergies. The aim of this study was to characterize the pattern of sensitization of atopic patients treated at different pediatric allergy referral centers in Brazil. Methods A nation-wide transversal multicenter study collected data on patients attended in Brazil. Peripheral blood samples were collected to determine the serum levels of allergen-specific IgE. If allergen-specific IgE was higher than 0.1 kUA/L, the following specific components were quantified. Results A total of 470 individuals were enrolled in the study. Mite sensitization was the most frequent kind in all participants. A high frequency of sensitization to furry animals and grasses featured in the respiratory allergies. Regarding components, there was a predominance of sensitization to Der p 1 and Der p 2. It has been verified that having a food allergy, atopic dermatitis, or multimorbidity are risk factors for the development of more severe allergic disease. Conclusion Studies on the pattern of allergic sensitization to a specific population offer tools for the more effectual prevention, diagnosis, and treatment of allergic diseases. Sensitization to dust mites house was the most prevalent in the evaluated sample. High rates of sensitization to furry animals also stand out. Patients with food allergy, atopic dermatitis, or multimorbidity appear to be at greater risk for developing more severe allergic diseases.

ABSTRACT Phytase enzyme is supplemented to poultry feed to improve phosphorus (P) availability. Mitsuokella jalaludinii, bacteria isolated from the rumen of cattle, has been reported as a cheaper alternative source of phytase. As much nutrients are trapped within the phytate complex, we hypothesized that the supplementation of M. jalaludinii phytase to poultry feed would enhance nutrient utilization by poultry. In the current study, the efficacy of freeze-dried M. jalaludinii cells (Mj) as feed supplement for broilers fed low-available phosphorus (low-aP) diet was evaluated. Day-old male Cobb raised in battery cages were assigned to three treatment groups [normal-available phosphorus diet with heat-deactivated Mj (DMj); low-aP diet with DMj; and low-aP diet with Mj], each consisting of four replicates (10 birds per replicate) for a 3-weeks feeding period. Feed intake was recorded daily from day 1-21, whereas broilers were weighted at day 1, 7, 14, and 21. Total excreta were collected at day 11-13 and 18-20. At day 21, twelve broilers from each treatment group were slaughtered to collect plasma and tibia. The results showed that Mj significantly enhanced broilers’ live weight and feed conversion ratio compared to the control groups (p<0.05). Supplementation with Mj have also enhanced the level of P, Ca, Mn, Cu, and Zn in the sera; and Ca and Mn in the tibia at day 18-20 sampling period (p<0.05). As Mj supplementation can enhance nutrient utilization particularly in broilers fed with low-aP diet, it could provide the market with another option in improving broilers’ growth rate at a lower cost.

Abstract Understanding the upstream migration of amphidromous prawns is important to address the impact of anthropomorphic activities in natural freshwater ecosystems. The ability of Macrobrachium tenellum (Smith, 1871) juveniles to overcome an artificial barrier was evaluated, simulating an obstacle in their upstream migration, under an experimental laboratory system. The prawns were collected from a stream located in Puerto Vallarta, Mexico (N = 1000). An experimental recirculation system was used, which consisted of a tank with a capacity of 600 L, a sheet of galvanized steel that acted as an anthropogenic barrier and two submersible electric pumps with flows of 0.12 L/s and 0.40 L/s. In this system, two inclinations of the barrier were tested, 45° and 90° in combination with the two flows. The results show that there are significant differences between the treatments with different inclinations, where a higher stimulation response was observed at the 90° angle. Within this inclination, the flow of 0.40 L/s produced the highest stimulation to climb the barrier in prawns between 30 and 60 mm in length. This study demonstrates the direct relationship between the slope and the effect of water flow of the anthropogenic barriers that hinder the migration process of M. tenellum.

ABSTRACT Objective: Our aim is to establish genetic diagnosis of congenital generalized lipodystrophy (CGL) using targeted massively parallel sequencing (MPS), also known as next-generation sequencing (NGS). Subjects and methods: Nine unrelated individuals with a clinical diagnosis of CGL were recruited. We used a customized panel to capture genes related to genetic lipodystrophies. DNA libraries were generated, sequenced using the Illumina MiSeq, and bioinformatics analysis was performed. Results: An accurate genetic diagnosis was stated for all nine patients. Four had pathogenic variants in AGPAT2 and three in BSCL2. Three large homozygous deletions in AGPAT2 were identified by copy-number variant analysis. Conclusions: Although we have found allelic variants in only 2 genes related to CGL, the panel was able to identify different variants including deletions that would have been missed by Sanger sequencing. We believe that MPS is a valuable tool for the genetic diagnosis of multi-genes related diseases, including CGL.

Pressed ceramic plates were made from mixtures with different proportions containing kaolinite clay, silica extracted from the rice husk ash after controlled burning at controlled temperature and sludge from a water treatment plant. Physical properties such as density, water absorption and porosity, mechanical properties such as compressive strength, and thermal characteristics such as thermal conductivity of the ceramic plates after burning (DIN EN12667) were evaluated. The silica when inserted in the kaolinite clay can have a gradual increase of its performance, be reduced in the porous phase, with reduction of the thermal conductivity and increase of the mechanical resistance. The use of the sludge from a water treatment plant when incorporated to the ceramic mass is a great number of peaks of charge and of crystallization, expressive increase of porosity and decrease of the thermal and mechanical resistances. As ceramic plates with a trace 72% kaolinite clay, 18% rice husk and 10% sludge from a water treatment plant show lower thermal conductivity 0.2574 W m-1K-1, and a higher compressive strength of 172.12 MPa when compared to the other plates tested where the substitutions for sludge from a water treatment plant occurred.

Abstract This study described a broad clinical characterization of classical homocystinuria (HCU) in Brazil. This was a cross-sectional, observational study including clinical and biochemical data from 72 patients (60 families) from Brazil (South, n = 13; Southeast, n = 37; Northeast, n = 8; North, n = 1; and Midwest, n = 1). Parental consanguinity was reported in 42% of families. Ocular manifestations were the earliest detected symptom (53% of cases), the main reason for diagnostic suspicion (63% of cases), and the most prevalent manifestation at diagnosis (67% of cases). Pyridoxine responsiveness was observed in 14% of patients. Only 22% of nonresponsive patients on treatment had total homocysteine levels <100 mmol/L. Most commonly used treatment strategies were pyridoxine (93% of patients), folic acid (90%), betaine (74%), vitamin B12 (27%), and low-methionine diet + metabolic formula (17%). Most patients diagnosed with HCU in Brazil are late diagnosed, express a severe phenotype, and poor metabolic control. Milder forms of HCU are likely underrepresented due to underdiagnosis.

Abstract Three-dimensional numerical simulations and experiments were performed to examine the formation and spatial dispersion patterns of integral multiple explosively formed penetrators (MEFP) warhead with seven hemispherical liners. Numerical results had successfully described the formation process and distribution pattern of MEFP. A group of penetrators consisting of a central penetrator surrounded by 6 penetrators is formed during the formation process of MEFP and moves in the direction of aiming position. The maximum divergence angle of the surrounding penetrator group was 7.8°, and the damage area could reach 0.16 m2 at 1.2 m. The laws of perforation dispersion patterns of MEFP were also obtained through a nonlinear fitting of the perforation information on the target at different standoffs. The terminal effects of the MEFP warhead were performed on three #45 steel targets with a dimension of 160cm ( 160cm ( 1.5cm at various standoffs (60, 80, and 120 cm). The simulation results were validated through penetration experiments at different standoffs. It has shown excellent agreement between simulation and experiment results.

Abstract: En | Text: En | PDF: En

SUMMARY P450 oxidoreductase deficiency (PORD) is a variant of congenital adrenal hyperplasia that is caused by POR gene mutations. The POR gene encodes a flavor protein that transfers electrons from nicotinamide adenine dinucleotide phosphate (NADPH) to all microsomal cytochrome P450 type II (including 21-hydroxylase, 17α-hydroxylase 17,20 lyase and aromatase), which is fundamental for their enzymatic activity. POR mutations cause variable impairments in steroidogenic enzyme activities that result in wide phenotypic variability ranging from 46,XX or 46,XY disorders of sexual differentiation, glucocorticoid deficiency, with or without skeletal malformations similar to Antley-Bixler syndrome to asymptomatic newborns diagnosed during neonatal screening test. Little is known about the PORD long-term evolution. We described a 46,XX patient with mild atypical genitalia associated with severe bone malformation, who was diagnosed after 13 years due to sexual infantilism. She developed large ovarian cysts and late onset adrenal insufficiency during follow-up, both of each regressed after hormone replacement therapies. We also described a late surgical approach for the correction of facial hypoplasia in a POR patient.

Megabalanus peninsularis is a key species in the rocky shore, particularly in Malpelo Island in the Eastern Tropical Pacific (ETP) where it dominates the mesolittoral zone and the infralittoral fringe. The size structure of M. peninsularis was determined to infer the population state (pyramid model) by measuring the basal diameter of individuals (n= 837) around the oceanic island. The species population distribution followed a bimodal pattern (class I-II and VII). The pyramid expansive model, with a relatively higher number of juveniles than adults suggests that the population is growing.

A case of unusual mortality was studied to elucidate the suspicion of toxicosis in a feedlot herd of 98 Boer goats. The basic diet consisted of conventional feedstuff, Mulato grass (B. ruzizienses- B. brizanta) forage from the own unit areas, hay produced from the same grass, and water ad libitum. There was a sub-acute curse mainly characterized by anorexia, progressive deterioration, ruminal paralysis in isolated cases, icterus in absence of fever in the majority of animals. Morbidity reached up to50 % and mortality up to 16%. As part of the case research, haematological, bacteriological, and serological studies were carried out. Pathomorphological studies were done on two of the dead animals. A hepatic-renal insufficiency and hemorrhagic diathesis due to an acute hepatic insufficiency were consistent with death cause. It was concluded that the process studied was caused by the consumption of Mulato grass as the unique fibrous food, due to the toxic effect of saponins present in this Brachiaria species.

Se investigó un evento de mortalidad inusual en un rebaño estabulado de 98 caprinos (23 machos y 75 hembras), de la raza Boer, ubicados en una unidad de crianza. La alimentación básica consistió en pienso de producción nacional, forraje de pasto Mulato (B. ruzizienses- B. brizanta), procedente del área forrajera de la propia unidad, heno elaborado a partir de la misma planta y agua ad libitum. Se realizaron estudios bacteriológicos, virológicos y hematológicos. A los animales fallecidos se les realizó la necropsia y se practicaron estudios histopatológicos. La manifestación tuvo un proceso de curso subagudo caracterizado, principalmente, por inapetencia, desmedro progresivo, parálisis ruminal en casos aislados, ictericia y ausencia de fiebre en la mayoría de los animales; posteriormente, se sucedieron afectaciones respiratorias. La morbilidad llegó al 50 % y la mortalidad alcanzó el 16% debido a un síndrome de insuficiencia hepato-renal y diátesis hemorrágica por insuficiencia hepática aguda. El proceso ocurrido se atribuyó a toxicosis por consumo de pasto Mulato como forraje y heno, debido a la existencia de saponinas en esta especie de Brachiaria.

The red claw crayfish Cherax quadricarinatus is native to freshwater habitats of northern Australia and Papua New Guinea. Its high reproductive and adaptive capacity in different environments allows it to be cultivated, where escaped individuals have established wild populations in countries far from their natural range. In the late 90's and beginning of the 21st century, this crayfish was introduced illegally along the coast of southern Jalisco. Mismanagement led to escape and dispersion. Currently there are wild crayfish in the Cajón de Peñas Reservoir and surrounding streams in northern Jalisco, Mexico. The aim of this study was to evaluate the presence of C. quadricarinatus in fisheries in this area of Jalisco and analyze its importance in generating economic benefits for fishermen, comparing these results with those of the fishery for M. americanum, whose fishery is traditional. To catch specimens, traps were set for 24 h in the La Sanja Stream and the Cajón de Peñas Reservoir. The results of the survey showed that C. quadrica rinatus is an important part of the crustacean catch in this area: 32% of the total catch in the stream corresponded to C. quadricarinatus and the rest to M. americanum. While 85% of the catch in the dam corresponded to C. quadricarinatus, only 15% referred to M. americanum. Crayfish fishing in the reservoir is now an important part of the productive activity of local families dependent on fishing. The ecological consequences of wild crayfish proliferation remain to be studied.

La langosta australiana de agua dulce Cherax quadricarinatus es un crustáceo nativo de ríos del norte de Australia y Papua Nueva Guinea. Su alta capacidad de reproducción y adaptación a diferentes ambientes le ha permitido establecer poblaciones silvestres en países lejanos a su área de distribución natural. A fines de los años 90 y comienzo del año 2000, este crustáceo se introdujo ilegalmente a lo largo de la costa del sur de Jalisco, México. La mala gestión motivó la fuga y dispersión de este crustáceo. Actualmente, se encuentran ejemplares en el embalse Cajón de Peñas y arroyos circundantes en el norte de Jalisco. El objetivo de este estudio fue evaluar la presencia de C. quadricarinatus en las capturas realizadas en la zona de Jalisco, y analizar su importancia en la generación de beneficios económicos para los pescadores, en comparación con la pesquería de M. americanum, que es una actividad tradicional. Para la captura de los especímenes, las trampas se colocaron durante 24 h en el arroyo La Sanja y en el embalse Cajón de Peñas. Los resultados mostraron que esta especie es parte importante de la captura de crustáceos en esta área. El 32% de la captura total en el arroyo correspondió a C. quadricarinatus y el resto a M. americanum. Mientras que el 85% de la captura en el embalse, correspondió a C. quadricarinatus y 15% a M. americanum. La pesca de esta langosta en el embalse es un componente importante de la actividad productiva para el sostenimiento de las familias locales. Sin embargo, no han sido aún investigadas las consecuencias ecológicas de su proliferación en los ríos y embalses de la región.

Abstract: En Es | Text: En Es | PDF: En | PDF: Es

This study revealed that the scientific interest in the genus Macrobrachium was not restricted to a biological point of view, but included also social and economic aspects. Many species of the genus are subject of traditional fisheries and culture worldwide. Several research groups across the globe have developed projects in various subject areas on commercial or non-commercial native species of this genus. This investigation aimed to contribute to the development of the genus Macrobrachium research through a scientometric study. The study was based on publications (1980 to 2013) registered in the following databases: Biological Abstracts, ISI Web of Science, SciELO Citation Index, BioOne, Science Direct, Scopus, and Redalyc. A total of 2165 publications on Macrobrachium in the last 33 years were included in this analysis. The themes that yielded most posts were related to culture, nutrition/feeding, and genetics with almost 60% of the total. Publications concerning M. rosenbergii represented more than 60% of the total with the remaining 40% encompassing 22 other species. Analysis performed by geographical regions evidenced that Latin America produced 23% of the publications, South Asia 22%, and East Asia 16%. Brazil generated 65% of the percentage mentioned for the Latin American region. It is necessary to strengthen research on topics of basic biology, especially those of native species. This will allow rapid progress in the generation of production technologies sustained by a solid biological knowledge base.

El interés científico por las especies del género Macrobrachium no ha sido sólo desde el punto de vista biológico, sino también económico y social. Muchas de sus especies son objeto de pesquerías tradicionales y cultivo. Diversos grupos de investigación del mundo han realizado trabajos sobre temáticas del conocimiento de especies nativas comerciales o no-comerciales. El presente trabajo pretende contribuir al desarrollo de la investigación del género Macrobrachium mediante análisis cienciométrico. Este estudio se basó en las publicaciones registradas en las siguientes bases de datos desde 1980 a 2013: Biological Abstracts, ISI Web of Science, SciELO Citation Index, BioOne, Science Direct, Scopus y Redalyc. El número total de publicaciones sobre Macrobrachium en los 33 años analizados fue de 2165. Las temáticas que más publicaciones mostraron (60% del total registrado) fueron las relacionadas con el cultivo, nutrición/alimentación y genética. Solo de M. rosenbergii se ha publicado más del 60% del total, el restante 39% de las publicaciones corresponde a 22 especies. El análisis por regiones geográficas puso en evidencia que Latinoamérica genera el 23%, Asia del Sur 22% y Asia Oriental 16% de los trabajos publicados. Sólo Brasil genera el 65% del total de Latinoamérica. Es necesario reforzar la investigación dirigida a temáticas de biología básica sobre todo en las especies nativas. Esto permitirá avanzar más rápidamente en la generación de tecnologías de producción sustentadas en una base sólida de conocimiento biológico.
