1. Semen quality from patients affected by seminomatous and non-seminomatous testicular tumor
ABSTRACT Testicular cancer is considered a rare disease affecting approximately 1% to 2% of the male population. This neoplasm has a cure rate of over 95%; as a result, a major concern is the future of fertility of carriers from this disease. There are several histological subtypes of testicular tumors; however, the Testicular Germ Cell Tumors (TGCTs), compr

2. Can plant hybridization and polyploidy lead to pollinator shift?
ABSTRACT Events of both hybridization and polyploidy are capable of completely restructuring the genome, modifying phenotypic traits and affecting ecological interactions. For plants, these changes may affect floral traits that are important for interactions with pollinators, which could lead to shifts in pollinator behavior and taxa between hybrids/polyploi

3. Biomass and nitrogen accumulation in white oat (Avena sativa L.) under water deficit
ABSTRACT Knowledge on nitrogen absorption rate by crops can indicate important managements, especially the definition of rates of this nutrient and the best time for topdressing application. This study aimed to evaluate and compare the accumulation of biomass and nitrogen in white oat cultivated under severe, moderate and no water deficit. Treatments consist

4. Effects of growth hormone in the central nervous system
ABSTRACT Growth hormone (GH) is best known for its effect stimulating tissue and somatic growth through the regulation of cell division, regeneration and proliferation. However, GH-responsive neurons are spread over the entire central nervous system, suggesting that they have important roles in the brain. The objective of the present review is to summarize a

5. Análise bioeconômica do farelo de arroz na recria de bezerras de corte em azevém
RESUMO Objetivou-se avaliar a economicidade, o desempenho produtivo e o desenvolvimento das estruturas corporais relacionadas ao trato reprodutivo de bezerras de corte mantidas exclusivamente em pastagem de azevém (Lolium multiflorum Lam.) ou em pastagem de azevém recebendo 0,5 e 1,0% do peso corporal (PC) de farelo de arroz integral (FAI) como suplemento.

6. Influence of high temperature on the reproductive biology of dry edible bean (Phaseolus vulgaris L.)
ABSTRACT: The aim of this study was to investigate the effect of heat stress on 12 bean genotypes through the analysis of their reproductive biology in terms of flowering, pollen viability, meiotic behavior, and production. Plants were grown in a climate chamber at 25-20 °C (day and night) and at a high temperature treatment 37-26 °C (day and night) from t

7. Nesting and reproductive habits of the solitary bee Centris analis in trap nests under a tropical climate
RESUMO A polinização é um fator essencial na produção agrícola mundial e existe a necessidade de aumentar o número de espécies de abelhas que podem ser criadas para a polinização na agricultura, como a abelha solitária coletora de óleo Centris (Heterocentris) analis (Fabricius, 1804). Aqui, os comportamentos de nidificação e reprodutivo dessa a

8. Sexual and reproductive traits of the pearl oyster shrimp Pontonia margarita (Decapoda: Palemonidae), symbiotically inhabiting the mantle cavity of the rugose pen shell Pinna rugosa (Bivalvia: Pinnidae)
ABSTRACT Symbiosis between decapods and mollusks provides a unique opportunity to examine some of the evolutionary strategies employed by marine invertebrates. We describe the sexual and reproductive traits of the pearl oyster shrimp, Pontonia margarita Verril, 1869, found symbiotically inhabiting the mantle cavity of the rugose pen shell, Pinna rugosa Sower

9. Farmacopuntura utilizando os acupontos Hou Hai e Bai Hui em protocolos de sincronização de estro em cabras
RESUMO Avaliou-se a eficiência da administração de subdoses de eCG nos acupontos Bai Hui e Hou Hai em protocolos de sincronização de estro em cabras. Na primeira etapa, 57 cabras foram distribuídas aleatoriamente em quatro tratamentos: T1- 300UI de eCG intramuscular (IM); T2- 60UI de eCG no acuponto Hou Hai; T3- 60UI de eCG no acuponto Bai Hui e T4- 60

10. Evaluation of food baits to capture Drosophila suzukii in the southern of Brazil
Abstract: Drosophila suzukii is one of the main pests of small fruits in the world. An effective monitoring is fundamental to detect the presence of the fly and to predict the infestation of fruits in new areas. We evaluated the food baits Ceratrap®, Torula®, Biofruit®, Suzukii Trap®, apple cider vinegar, and a homemade mixture comprising wine, vinegar a

11. Run to the nest: A parody on the Iron Maiden song by Corotoca spp. (Coleoptera, Staphylinidae)
Abstract Rove beetles belonging to the genus Corotoca (Staphylinidae: Aleocharinae) are termitophiles exclusively found in nests of Constrictotermes (Isoptera: Termitidae). We observed the reproductive behavior of Corotoca melantho and C. fontesi during host (Constrictotermes cyphergaster) foraging events. The reproductive behaviors of both species are simil

12. REPRODUCTIVE EFFICIENCY AND BEHAVIOR OF PREGNANT SOWS HOUSED IN CAGES AND COLLECTIVE PENS WITH OR WITHOUT BEDDING
ABSTRACT This study aimed to evaluate the effect of wood shaving bedding on pregnant sows under two housing conditions. Sixty-four animals were distributed into four treatments, each treatment included 54 sows split into three replicates. A 2 × 2 factorial design was used (two types of housing, collective pens (CP) and combined housing (cages + CP [CCP]); a
