1. Corticotropin-releasing factor receptor signaling and modulation: implications for stress response and resilience
Abstract Introduction In addition to their role in regulation of the hypothalamic-pituitary-adrenal-axis, corticotropin-releasing factor (CRF) and its related peptides, the urocortins, are important mediators of physiological and pathophysiological processes of the central nervous, cardiovascular, gastrointestinal, immune, endocrine, reproductive, and skin

2. Evidence of accelerated and altered pollen development after Imazapyr treatment in resistant sunflower
ABSTRACT Imazapyr (IM) treatment applied at early reproductive developmental stages have been associated with induced male sterility in sunflower (Helianthus annuus L.). The aim of this work was to determine the effects induced by two different doses of IM-treatment (1X and 2X; 80 and 160 g a.i.·ha-1) on pollen grain yield, pollen viability and on the exine

3. Phenotypic variation and heritability of heading date in hexaploid oat
Abstract The onset of flowering is decisive to the reproductive success of plants. The objectives of this study were to characterize the phenotypic variation in heading date and estimate its heritability in segregating populations of oat (Avena sativa L.). F2 and F3 generations of two large populations, derived from crosses ‘URS Taura × Leggett’ and ‘

4. Bioactive compounds in edible flowers of garden pansy in response to irrigation and mycorrhizal inoculation
ABSTRACT Edible flowers have been increasingly used in the Brazilian gastronomy because they are considered functional foods with high antioxidant potential. Studies on the management of cultivation of edible flowers to increase the production of bioactive compounds have been developed aiming at the improvement of production systems. The objective of this wo

5. Serological response against bovine herpesvirus and bovine viral diarrhea virus induced by commercial vaccines in Holstein heifers
RESUMO: A vacinação é utilizada como estratégia para a prevenção e controle das doenças reprodutivas, causadas pelos vírus da diarreia viral bovina (BVDV) e herpesvírus bovino tipo 1 (BoHV-1), entretanto, as diversas composições de vacinas comerciais devem ser avaliadas quanto a sua eficiência protetiva mediada por anticorpos (Acs). O objetivo de

6. Stress, strain, and pregnancy outcome in postpartum cows
Abstract Stress affects the productivity and fertility of cattle. Stress causes strain and individual animals experience different amounts of strain in response to the same amount of stress. The amount of strain determines the impact of stress on fertility. Typical stresses experienced by cattle include environmental, disease, production, nutritional, and ps

7. Inflammation: friend or foe of bovine reproduction?
Abstract Inflammation is not only the first line of defense of the organism but is also required in many reproductive processes such as ovulation, corpus luteum development, luteolysis, uterine clearance after insemination and post partum. Nevertheless, if excessive or persistent, inflammation can switch from a positive mechanism to a deleterious process, im

8. Pre-TAI protocol strategies to increase reproductive efficiency in beef and dairy cows
Abstract Ovulation synchronization protocols are well established in beef and dairy cows. However, the protocol response rate is around 70-90%. In beef cows, factors such as inadequate nutrition and calf presence negatively impact the response of progesterone (P4)/estradiol-based ovulation synchronization protocols by interfering with GnRH release and conseq

9. DNA methylation, environmental exposures and early embryo development
Abstract The first crucial step in the developmental program occurs during pre-implantation, the time after the oocyte has been fertilized and before the embryo implants in the uterus. This period represents a vulnerable window as the epigenome undergoes dynamic changes in DNA methylation profiles. Alterations in the early embryonic reprogramming wave can im

10. Interleukin-6 in pregnancy with sickle cell disease
ABSTRACT Background: Despite advances in health care for sickle cell disease patients, as well as in the improvement in reproductive issues mainly in women with the disease, pregnancy is still a challenge, both for the mother and the child, with high rates of maternal and fetal morbidity and mortality. Besides their chronic hemolytic status and vaso-occlusi

12. MALE ADULT RAT SPERM PARAMETERS AFTER SKELETAL MUSCLE INJURY
RESUMO Introdução: As lesões músculo-esqueléticas estimulam uma resposta inflamatória sistêmica que pode interferir na reprodução das espécies. Objetivo: Avaliar os efeitos causados pelas lesões músculo-esqueléticas sobre a resposta inflamatória e os parâmetros espermáticos de ratos machos adultos. Métodos: O grupo da amostra foi composto
