1. Expression Analysis of Pyrenophora teres f. maculata-Responsive Loci in Hordeum vulgare
Abstract Pyrenophora teres f. maculata is the causal agent of barley spot form net blotch (SFNB), a major stubble-borne disease in many barley-growing areas worldwide. In plants, the Nucleotide-Binding Site-Leucine-Rich Repeat (NBS-LRR) gene family functions in immunity against a variety of pathogens and pests. From a pre-established set of NBS-type resistan

2. Larvicidal and adulticidal effects and ultrastructural changes of larvae midgut epithelium of Musca domestica (Diptera: Muscidae) fed with Bacillus thuringiensis var. kyushuensis
Abstract INTRODUCTION: Musca domestica is resistant to many insecticides; hence, biological control is a suitable alternative. METHODS: We evaluated the lethality of strain Btk176 towards the larval and adult M. domestica and the histopathological effects in the larvae midgut. RESULTS: We observed 99% larval and 78.9% adult mortality within 48 hours of sp

3. Hepcidin is a useful biomarker to evaluate hyperferritinemia associated with metabolic syndrome
Abstract: Investigation of hyperferritinemia in metabolic syndrome patients represents a diagnostic challenge, but it is essential for the identification of individuals with iron overload. Hepcidin negatively regulates iron absorption and release. An increase in hepcidin occurs when iron levels are sufficient or in inflammatory states, conditions often assoc

4. Effect of low power laser in biomodulation of cultured osteoblastic cells of Wistar rats
Abstract Purpose: To analyze aspects of the biomodulating effect of light in biological tissues, bone cells from surgical explants of the femur of rats were irradiated with low intensity laser. Methods: Bone cells were cultured and irradiated with LASER light (GaAlAs). Growth, cell viability, mineralized matrix formation, total protein dosage, immunostim

5. Perspectives for cancer immunotherapy mediated by p19Arf plus interferon-beta gene transfer
While cancer immunotherapy has gained much deserved attention in recent years, many areas regarding the optimization of such modalities remain unexplored, including the development of novel approaches and the strategic combination of therapies that target multiple aspects of the cancer-immunity cycle. Our own work involves the use of gene transfer technology

6. ACE gene dosage determines additional autonomic dysfunction and increases renal angiotensin II levels in diabetic mice
OBJECTIVES: The present study aimed to investigate cardiovascular autonomic modulation and angiotensin II (Ang II) activity in diabetic mice that were genetically engineered to harbor two or three copies of the angiotensin-converting enzyme gene. METHODS: Diabetic and non-diabetic mice harboring 2 or 3 copies of the angiotensin-converting enzyme gene were

7. Vegetable and fruit juice enhances antioxidant capacity and regulates antioxidant gene expression in rat liver, brain and colon
Abstract To explore the effect of fruit and vegetable (FV) juice on biomarkers of oxidative damage and antioxidant gene expression in rats, 36 adult male Wistar rats were randomly divided into control, low FV juice dosage or high FV juice dosage treatment groups. The rats were given freshly extracted FV juice or the same volume of saline water daily for five

8. Pesquisa de mutações no gene DMRT1 em pacientes portadores de distúrbios do desenvolvimento sexual (DDS) 46,XY por anormalidades gonadais / Search of mutation on DMRT1 gene in patients with 46,XY disorders of sex development (DSD) by gonads abnormalities
Introdução: O gene DMRT1 é um fator muito importante, o qual induz a determinação sexual masculina. Estudos mais recentes têm demonstrado que o Dmrt1 possui um papel significante no desenvolvimento ovariano. Deleções restritas ao gene DMRT1 têm sido raramente identificadas em pacientes com disgenesia gonadal (DG) sem outras características sindrôm

9. Relationship between grain colour and preharvest sprouting-resistance in wheat.
Since red alleles (R) of the genes that control grain colour are important for the improvement of preharvest sprouting resistance in wheat and there are three independently inherited loci, on chromosomes 3A, 3B and 3D of hexaploid wheat, it is possible to vary the dosage of dominant alleles in a breeding program. The objective of this work was to evaluate th

10. Análise da variação cariotípica e dos mecanismos de recombinação em leveduras industriais (Saccharomyces cerevisiae) durante o processo de fermentação alcoólica / Analysis of the karyotypic variation and the recombination mechanisms industrial yeast (Saccharomyces cerevisiae) during the alcoholic fermentation process
Brazilian sugar cane ethanol stands out among the energetic alternatives available nowadays. In the fermentation process to produce ethanol it is used the yeast Saccharomyces cerevisiae. One of the most widely adopted strains is the industrial isolate PE-2, currently used by ~30% of Brazilian distilleries, generating ~10% of the worlds ethanol supply. This

11. Estudo do padrão de inativação do cromossomo X em tecido extra-embrionário humano / X-chromosome inactivation pattern in human extra-embryonic tissue
Imprinted inactivation of the paternal X chromosome in marsupials is the primordial mechanism of dosage compensation for X-linked genes between females and males in Therians. In Eutherian mammals, X chromosome inactivation (XCI) evolved into a random process in cells from the embryo proper, where either the maternal or paternal X can be inactivated. However,

12. Intermittent HIV-1 viremia (blips) and virologic failure in patients under antiretroviral therapy: incidence and associated factors / Escape transitório da viremia plasmática de HIV-1 e falência virológica em indivíduos sob terapêutica anti-retroviral: incidência e fatores associados
INTRODUÇÃO: Pacientes em terapia anti-retroviral podem apresentar escapes transitórios de viremia plasmática (blip), porém os preditores desse evento e seu impacto sobre a incidência de falência virológica são ainda controversos na literatura. Neste estudo de coorte estimou-se a incidência de blip e de falência virológica e investigaram-se possí
