Antimicrobial peptides extracted from ovine neutrophils have potential to be high-value by-products of the lamb industry as, for example, a biopreservative for chilled lamb products. This work was carried out to determine the conditions in which ovine peptides are most effective and to assist in product development. The activities of three synthetic ovine-derived antimicrobial peptides tested w...

Rice is becoming a model plant in monocotyledons and a model cereal crop. For better understanding of the rice plant, it is essential to elucidate the developmental programs of the life cycle. To date, several attempts have been made in rice to categorize the developmental processes of some organs into substages. These studies are based exclusively on the morphological and anatomical viewpoints...

Ultrastructural observations of the in utero sperm of Ascaris lumbricoides reveal that it consists of a relatively clear, ameboid anterior region and a conical posterior region containing numerous surface membrane specializations, dense mitochondria, a lipid-like refringent body of variable size, and a dense nucleus which lacks an apparent nuclear envelope. No acrosomal complex was observed. Ps...

The aim of this study was to investigate the effects of iron and copper on bovine oocyte maturation, preimplantation embryo development and apoptosis of blastocysts. The concentrations of iron in the culture media were 0 (control), 0.45, 0.81, 1.96 and 3.26 mg/l, and the concentrations of copper were 0 (control), 0.093, 0.27, 0.46 and 0.68 mg/l. The changes in the iron (1.96 mg/l) and copper co...

Coxiella burnetii, the etiological agent of Q Fever, is a zoonotic pathogen distributed worldwide. It has been reported that virulent strains of C. burnetii are poorly internalized by monocytes compared to avirulent variants. Virulence is also associated to the formation of pseudopodal extensions and transient reorganization of filamentous actin. In this article, we investigated the ability of ...

PURPOSE Currently, no studies exist, which attest the suitability of the ovine intervertebral disc as a biomechanical in vivo model for preclinical tests of new therapeutic strategies of the human disc. By measuring the intradiscal pressure in vivo, the current study attempts to characterize an essential biomechanical parameter to provide a more comprehensive physiological understanding of the ...

Abstract Ovine respiratory complex is a significant cause of death in sheep flocks, where Pasteurella multocida the most frequent microorganisms isolated from animals with pneumonia. There an urgent need to refine use different antimicrobials avoid problem antimicrobial resistance and optimize control this disease ovine livestock. The first step approaching gaining insight into susceptibility p...

ABSTRACT This study aimed to evaluate sweet potato feed as an alternative energy supplement for ovine. A latin-square design was used assess the effects of feeding animals 0, 0.5, 1 and 1.5% their body weight in well ryegrass hay (Lolium multiflorum) twice daily, mineral salt water ad libitum. During this 8 males were housed metabolic cages with urine feces collectors. Each round experimentatio...
