Abstract Objective The present study aimed to evaluate the effects of GH treatment on the body composition of children born with SGA. Methods This study is a systematic review of the literature. CINAHL, Embase; Medline/Pubmed, Scopus and Web of Science were searched from inception to March 2022. Results Four studies met the inclusion criteria, with an intervention time of 1 to 3 years, using doses from 0.03 to 0.07 mg/kg/day of GH. Bone densitometry by dual-energy X-ray absorptiometry (DXA) with whole-body scans was the most used method to assess body composition. Most studies (n= 3) had SGA children as a control group with the same characteristics as the case group; the mean age was similar between the groups (minimum of 5.1 ± 1.4 years and maximum of 6.7 ± 1 0.8 years) and all participants had an average height ≤ -3DP. The Lean Mass (LM) and Fat Mass (FM) outcomes of the studies were not presented in a standardized manner; thus, they cannot be compared. There was a significant increase in LM in the group treated with GH in relation to the pre-treatment period and in comparison, to the untreated control group. Three studies showed a significant decrease in FM at the end of the intervention period, and in two studies, this decrease occurred in the control group. Conclusions Despite the differences in the presentation of results and in the evaluation periods, the results of the studies showed that growth hormone favors the gain and maintenance of lean mass, and it also affects fat mass reduction and redistribution.

RESUMO: Este experimento foi conduzido com o objetivo de avaliar os efeitos da quantidade e tipo de dieta consumida durante o intervalo desmame-estro (IDE) sobre o desempenho ao parto subsequente e tempo de IDE de fêmeas suínas. Foram utilizadas 542 fêmeas, distribuídas em um delineamento fatorial 2×2 com duas quantidades de alimento fornecido durante o IDE (2,75 ou 3,75 kg/dia) e dois tipos de dieta (gestação - G ou lactação - L), sendo: Alto fornecimento de dieta G (GA), menor fornecimento de G (GM), alto fornecimento de L (LA) e menor fornecimento de L (LM). As fêmeas foram aleatoriamente distribuídas entre os tratamentos em blocos de acordo com o escore corporal Caliper e ordem de parto. Houve interação para tempo de IDE (P<0,05) entre a quantidade de ração e o tipo da dieta consumida durante o período, o qual foi 0,2 dias mais curto nos grupos GA e LM. Não houve diferença entre os tratamentos (P>0,05) sobre a taxa de parto, total de nascidos, natimortos e peso total da leitegada. Houve uma tendência para maior taxa de nascidos vivos (P<0,10) nas fêmeas que consumiram a dieta G, e nas fêmeas que receberam o menor fornecimento de ração, com média de 91,95%, para ambos os fatores. Além disso, foi observada tendência positiva (P<0,10) para o peso vivo da leitegada, em que GA e LM apresentaram maior peso ao nascer (17,9 e 17,7 kg, respectivamente). Em conclusão, o fornecimento de 3,75 kg/dia, ou o uso de uma dieta mais energética (lactação) durante o IDE, não melhora o desempenho reprodutivo do ciclo subsequente de fêmeas suínas em boa condição corporal.

ABSTRACT: This study was conducted to evaluate how the amount and type of diet consumed during the wean-to-estrus interval (WEI) affects reproductive performance and WEI duration in sows. A total of 542 sows were distributed into the following treatment groups based on a 2 × 2 factorial design: feed amount during WEI (2.75 or 3.75 kg/day) and diet (gestation [G] or lactation [L]) groups. Dietary treatments were as follows: high supply of G diet (GH), low supply of G diet (GL), high supply of L diet (LH), and low supply of L diet (LL). Sows were randomly allocated to groups according to their body score Caliper and birth order. There was an interaction (P < 0.05) between the factors for WEI duration, which was 0.2 days shorter in the GH and LL groups than in the other groups. No difference was observed between treatments (P>0.05) for the birth rate, total births, stillbirths, or total litter weight. There was a trend (P<0.10) toward a higher rate of live births in sows fed with G diet and sows receiving a low diet supply, with an average of 91.95% for both groups. In addition, there was a positive trend (P < 0.10) for live weight of the litter, where GH and LL treatments resulted in higher birth weight (17.9 and 17.7 kg, respectively) than other treatments. In conclusion, a supply of 3.75 kg/day or the use of a more energetic feed (lactation) during the WEI did not improve the reproductive performance of the subsequent cycle of sows in good body condition.

Resumo Avaliar os fatores associados ao consumo de leite materno (LM), fórmulas lácteas (FL) e leite de vaca (LV). Estudo de coorte com 247 crianças acompanhadas no 1°, 4° e 6° mês de vida, em Viçosa-MG. Para o LV e FL contabilizouse o consumo independentemente da ingestão de LM. Para o LM, considerou-se apenas o consumo exclusivo ou predominante. Do 1° ao 6° mês observou-se o aumento do não consumo de LM de forma exclusiva ou predominante (31,6%), bem como do consumo de LV (27,2%) e FL (9,3%). O LM associou-se ao uso de chupeta no 1° mês, e ao trabalho materno e uso de chupeta no 4° e 6° mês. O uso de chupeta foi fator de risco para o consumo de FL em todos os meses, enquanto pertencer ao grupo de menor renda foi inversamente associado no 6° mês. Para o LV, o número de consultas pré-natal foi fator de risco em todos os meses, o trabalho materno e o uso de chupeta no 4° mês, a renda familiar, trabalho materno, baixo peso ao nascer, número de consultas pré-natal e uso de chupeta no 6° mês. Desde o 1° mês a introdução de outros tipos de leite é elevada, revelando que ainda há muito a se percorrer para a garantia do aleitamento materno exclusivo até os 6 meses.

Abstract This study evaluated factors associated with the consumption of breast milk (BM), infant formula (IF) and cow milk (CM) in children. This was a cohort study with 256 children followed-up at the 1st, 4th and 6th month of age in Viçosa (MG), Brazil. With respect to CM and IF, consumption was recorded regardless of BM intake. Regarding BM, only exclusive or predominant consumption was considered. From the 1st to the 6th month, an increase was recorded in the number of children who did not consume BM exclusively or predominantly (31.6%), as well as the consumption of CM (27.2%) and IF (9.3%). BM was associated with pacifier use at 1st month, and mother's employment status and pacifier use in the 4th and 6th month. Pacifier use was a risk factor for IF consumption in every month, while belonging to the lower income group was inversely associated in the 6th month. As for CM, the number of prenatal visits was a risk factor in every month, the mother's employment status and use of pacifier in the 4th month, family income, mother's employment status, low birth weight, number of prenatal visits and pacifier use in the 6th month. Since the 1st month, the introduction of other milk types is high, revealing that there is still much to go to ensure exclusive breastfeeding up to 6 months.

Este trabalho teve como objetivo comparar a atividade respiratória em mitocôndrias isoladas e os atributos físicos e químicos da polpade dois híbridos de mamão, UENF/Caliman01 (UC01) e Tainung01,durante o amadurecimento dos frutos. Oamadurecimento dos frutos não mostrou diferenças significativas entre os genótipos na luminosidade (L), no croma (C) e no ângulo hue da casca. A perda de massa (PM)e as firmezas do fruto (FF) e domesocarpo (FM) diferiram entre os genótipos, sendo que a FF e a FM diminuíram com o tempo após a colheita,ao contrário da PM, que aumentou no mesmo período. A atividade respiratória nas mitocôndrias isoladas mostrou diferenças entre os genótipos quanto à respiração total (RT), sendo maior e decrescente no Tainung01 e constante no UC01 durante o amadurecimento dos frutos. Durante esse período, verificou-se que a participação da via oxidase alternativa (AOX) foi crescente, contra uma participação decrescente da via citocromo oxidase (COX) em ambos os híbridos, indicando um crescente desacoplamento das mitocôndrias, o que pode estar associado às rápidas transformações bioquímicas que acarretam a senescência do órgão. A partir desses resultados, sugere-se investigar materiais genéticos com menor atividade AOX, ou formas de minimizar a atividade respiratória nos frutos em pós-colheita. A AOX apresentou alta correlação positiva com a PM e negativa com a FF e a FM. O inverso foi observado para COX. A RT apresentou correlação positiva apenas com a FM. As correlações apontam a viabilidade de estimar a atividade respiratória por meiode análises mais simples, como a PM, a FF e a FM, facilitando a pesquisa na área.

This study had the object of comparing the respiratory activity in isolated mitochondria and the physical and chemical attributes of the pulp of two papaya hybrids, UENF/Caliman01 and Tainung01, during fruit ripening. The fruit ripening did not show significant differences between the genotypes with regard to lightness (L), chroma (C), and hue angle of the skin. The loss of mass (LM) and the firmness of fruit (FF) and mesocarp (FM) differed between the genotypes, with FF and FM decreasing with time after harvest, while LM rose over the same period. The respiratory activity in the isolated mitochondria revealed differences between the genotypes with respect to total respiration (TR), being higher and with negative time-correlation function in Tainung01 and constant in UC01 during fruit ripening. During this period the participation of alternative oxidase (AOX) pathway was crescent, against the decreasing participation of cytochrome c oxidase (COX) pathway in both hybrids was verified, indicating an increasing uncoupling of the mitochondria, which may be associated with the rapid biochemical transformations that cause the senescence of the organ. From these results, investigating genetic materials with lower AOX activity or ways of minimizing the respiratory activity in postharvest fruit is suggested. The AOX presented the high positive correlation with LM and negative with FF and FM while the inverse was observed for COX. The TR presented positive correlation only with the FM. The correlations indicated the viability of estimated respiratory activity through simpler analyses such as LM, FF, and FM, thus facilitating studies in the area.

Abstract: En | Text: En | PDF: En

Isolates of Salmonella sp (104) from poultry samples were isolated and serotyped where eleven were identified as Salmonella Typhimurium (ST). ST isolates were phenotypically tested by disk diffusion and minimum inhibitory concentration (MIC). Four genes related to enrofloxacin (GyrA, GyrB, ParC and ParE), two to gentamicin (AadA and AadB) and two to ceftiofur (BlaCMY-2 and AmpC) resistance were searched by PCR. Our results showed ST resistance to all three antibiotics tested (18.1% for ceftiofur, 45.4% for gentamicin, and 18.1% for enrofloxacin) according to the diffusion test. In the MIC test, the ST isolates showed higher levels of resistance (27.2% for ceftiofur, 54.5% for gentamicin, and 18.2% for enrofloxacin). Three resistance genes out of four searched genes for enrofloxacin were found in the ST isolates. Regarding gentamicin and ceftiofur, resistance genes were found mainly in samples with resistant phenotypic profile. Interestingly, some phenotypically-resistant strains did not present the resistance gene, which suggests an alternative route of resistance. Also, sensitive strains had the presence of the gene. It is possible to conclude that the ST isolates evaluated in this study have a multidrug resistance profile to the antibiotics routinely used in poultry production, and potential of greater levels of resistance in the near future.

O objetivo do presente estudo foi comparar os efeitos do treino de força (TF) e do respectivo destreinamento entre dois modelos de periodização do volume (linear - ML; não linear - MNL) em jovens voleibolistas. A amostra foi composta por 12 jovens do sexo masculino jogadores de voleibol (17.1 ± 0.5 anos), divididos em dois grupos homogêneos. Os resultados sugerem que 8 semanas de TF induzem modificações significativas nos indicadores da força, independentemente do modelo de periodização utilizado. Contudo, o MNL parece menos eficaz no desenvolvimento da força explosiva em habilidades motoras específicas (salto vertical). Os resultados indicam que 4 semanas de destreinamento são suficientes para provocarem perdas significas na força muscular em jovens voleibolistas. O destreinamento de um ML induz a perdas significativas na força explosiva do trem superior (lançamento de bola medicinal) e inferior (salto vertical), enquanto que no MNL parece diminuir significativamente a força dinâmica máxima (supino) e o desempenho no salto vertical.

This study aimed to compare the effects of strength training (ST) and detraining (DT) of two volume periodization models (linear - LM; non linear - NLM) in young male volleyball players. 12 volleyball players (17.1±0.5 years old) were randomly divided into two groups. The results of the present study suggest that 8 weeks of ST induce changes in the indicators of increased maximal strength and explosive strength, regardless of models used. However, the NLM seems less effective in the development of explosive strength in specific motor skills (vertical jump). As for DT, this study suggests that 4 weeks is sufficient to cause significant losses as an indicator of release between the two models of training. The LM induces significant losses in the explosive strength of the upper (medicine ball throwing) and lower body (vertical jump), while the NLM suggests higher losses in the maximum strength (train top) besides the jumping ability.

Abstract: En | Text: En | PDF: En

In the present study we investigated the flagellin-specific serum (IgG) and fecal (IgA) antibody responses elicited in BALB/c mice immunized with isogenic mutant derivatives of the attenuated Salmonella enterica serovar Typhimurium (S. Typhimurium) SL3261 strain expressing phase 1 (FliCi), phase 2 (FljB), or no endogenous flagellin. The data reported here indicate that mice orally immunized with recombinant S. Typhimurium strains do not mount significant systemic or secreted antibody responses to FliCi, FljB or heterologous B-cell epitopes genetically fused to FliCi. These findings are particularly relevant for those interested in the use of flagellins as molecular carriers of heterologous antigens vectored by attenuated S. Typhimurium strains.

Abstract: En | Text: En | PDF: En

The pathogenicity of insect-pathogenic hyphomycetous isolates to the lesser mealworm Alphitobius diaperinus (Panzer) was tested in this study. Thirty isolates of Beauveria bassiana (Balsamo) Vuillemin, Paecilomyces amoenoroseus (Hennings), P. fumosoroseus (Wize) Brown & Smith, P. lilacinus (Thom) Samson, P. tenuipes (Petch) Samson, Metarhizium anisopliae (Metschnikoff) Sorokin, and M. anisopliae var. acridum were initially screened by sprinkling dry conidia onto adult A. diaperinus or by allowing adults to walk on Petri dishes with sporulating fungal isolates. The two most virulent isolates, CNPSo-Ma352 (M. anisopliae) and CNPSo-Ma356 (M. anisopliae), killed 30% and 26.7% of the dry-conidia treated adults, respectively. These two isolates were selected for LD50 bioassays. LD50 of CNPSo-Ma352 was 4.5 x 10(4) conidia per larva, and 2.1 x 10(5) conidia per adult, and for strain CNPSo-Ma356, LD50 was 2.2 x 10(4) conidia per larva and 1.3 x 10(5) conidia per adult. Larvae were 5-6 times more susceptible than adults. A larger number of conidia required to cause 50% mortality in insect evaluates, suggesting the reduced susceptibility of A. diaperinus to entomopathogenic fungi. Nevertheless, these and other strains of fungus offer an alternative method for controlling of lesser mealworm in poultry houses when associated to integrated management.

O objetivo deste trabalho foi realizar o isolamento de bactérias da família Enterobacteriaceae em adultos de A. diaperinus, buscando uma correlação entre as bactérias presentes no inseto e na cama, em aviários para produção de frangos de corte no oeste do Paraná, Brasil. No primeiro experimento, insetos adultos foram coletados em 14 granjas. No segundo experimento, foram coletados insetos e material da cama de 12 diferentes aviários. Os adultos foram anestesiados com éter, macerados em solução salina e o material da cama colhido por "swab" de arrasto. O enriquecimento não seletivo foi feito com caldo BHI e o seletivo com Rappaport-Vassiliadis e Tetrationato. Os meios de cultivo para plaqueamento foram o ágar MacConkey, ágar Salmonella-Shigella e ágar verde-brilhante. As enterobactérias isoladas em adultos de A. diaperinus foram: Proteus Vulgaris, P. mirabilis, Escherichia Coli, Enterobacter spp., E. agglomerans, E. gergoviae, E. sakasakii, Citrobacter Diversus e Klebsiella Pneumoniae, enquanto que na cama foram encontrados Proteus Vulgaris, P. mirabilis, Escherichia Coli, Enterobacter Agglomerans. Não foram isoladas Salmonella spp. do inseto nem da cama e P. vulgaris foi a predominante. E. coli foi freqüente nas granjas, tanto na cama como nos insetos e contribuem na disseminação da colibacilose em aviários.

This study was conducted to determine bacterial species of Enterobacteriaceae in adults of lesser mealworm, A. diaperinus and make the correlation of the bacterial species in the insects and in the litter that infest poultry brooder houses in West of Parana State, Brazil. In the first experiment, the adults were collected in 14 poultry houses. In the second experiment the insects and the litter were collected in 12 poultry houses. The adults were anaesthetized with eter, macerated in sterile saline solution and the litter material was taken off by swab. The enrichment broth was plated on the BHI and in Rappaport-Vassiliadis and Tetrationate. The agar MacConkey, agar Salmonella-Shigella and agar brilliant green was used as plating media for isolating the enterobacteria. The enterobacteria isolated in adults of A. diaperinus were: Proteus Vulgaris, P. mirabilis, Escherichia Coli, Enterobacter spp., E. agglomerans, E. gergoviae, E. sakasakii, Citrobacter Diversus and Klebsiella Pneumoniae. In the litter were found Proteus Vulgaris, P. mirabilis, Escherichia Coli, Enterobacter Agglomerans. There was no Salmonella spp . found in the insect and the litter and P. vulgaris was predominant. E. coli was found in the poultry houses, in the litter and the insects and the bacteria are responsible for dissemination of colibacilose.
