ABSTRACT Scedosporium apiospermum , the anamorphic form of Pseudallescheria boydii , is a filamentous fungus with low inherent virulence. Increasing numbers of cases of this infection have been reported probably related to the rising number of immunosuppressed persons. Apart from mycetoma, cutaneous and subcutaneous infection is rarely encountered in clinical practice. We describe a case of cutaneous infection caused by Scedosporium apiospermum in a subject with rheumatoid arthritis and diabetes mellitus ...

ABSTRACT A 40‐year‐old Caucasian man, originating from Ukraine, but living for the last year and a half in Portugal, presented to our department with a one year history of an irregular penile mass and phimosis. He reluctantly admitted that 8 years previously he had multiple mineral oil injections in the penis , for the purpose of penile enlargement. A diagnosis of penile paraffinoma was made and surgical excision was performed at the urology department. Paraffinoma results from mineral‐oil injections : ...

The effects of eggshell quality and breeder age were assessed on egg weight loss during incubation, fertility, hatchability, and embryonic mortality. The trials involved hatching eggs from three commercial broiler breeder flocks of the same strain but of different ages. The eggs were divided according to specific gravity into two groups, thin-shelled (< or = 1.080) and thick-shelled (> 1.080). Thin-shelled eggs displayed a greater increase in weight with breeder age and greater weight loss during incubation. ...

Pastures are assumed to be good sources of α-linolenic acid (ALA) and other bioactive compounds. In this study, we evaluated the effects of restricting the intake of a cereal-based feed on the consumption of a legume-based pasture, and consequently on poultry performance and meat quality. Broilers of the RedBro Cou Nu × RedBro M genotype were fed a cereal-based feed at different intake restriction levels (100, 75, or 50% of ad libitum intake) in portable floorless pens located on a subterranean clover ( ...

The correlation between apoptosis and early bovine embryonic loss is still not fully elucidated. In the present study, the relationship between the arrest of bovine embryos at the different stages of development and apoptosis was evaluated. We used embryos 7 days after in vitro maturation and fertilization, and morphologic and biochemical apoptotic analyses were performed by using a phase contrast microscope and by the terminal transferase dUTP nick end-labelling respectively.

Dehydrated forages are assumed to be good sources of α-linolenic acid (ALA) and lipid-soluble antioxidant compounds (vitamin E homologs and β-carotene). The effects of including a dehydrated leguminous-based forage in a typical diet for broiler chicken, on performance, meat quality, and fatty acid composition were evaluated. One hundred sixty 1-d-old male commercial broiler chicks (Ross 308) were housed in 20 battery brooders. During the 28-d growth period, the animals were fed ad libitum with a typical ...

Contents The overall aim of the present study was to evaluate in vitro development ability of oocytes recovered from 56 Holstein Frisian heifers with low [group 1 (G1): <13 mg /dl], moderate [group 2 (G2): 13–16 mg /dl] and high [group 3 (G3): >16 mg /dl] plasma urea nitrogen (PUN) concentrations, to determine whether PUN concentrations affect the competence of oocytes to progress to blastocysts after in vitro fertilization. In vitro oocyte and embryo development was assessed by blastocyst rates, embryo total ...

Antioxidants are compounds that protect cells against the damaging effects of reactive oxygen species (ROS) such as singlet oxygen, superoxide, peroxyl radicals, hydroxyl radicals and peroxynitrite.Oxidative damage occurs to cells in vivo and in vitro from exposure to free radicals generated by exogenous agents (e.g., radiation, chemicals, hyperoxia) and endogenous processes such as normal cellular metabolism.An imbalance between antioxidants and ROS results in oxidative stress, leading to cellular ...

Free-range chickens are assumed to consume low to moderate levels of pasture, although the effects of forage intake in broiler performance and poultry meat quality remain to be established. In addition, despite cellulases and hemicellulases being widely used as feed supplements to improve the nutritive value of cereal-based diets for fast-growing broilers, the potential interest of these biocatalysts in the production of free-range chicken is yet to be established. In this study, broilers of the ...

The aim of this study was to test the hypothesis that bulls have significant intra-individual differences in the hydraulic conductivity (Lp) and permeability coefficient for glycerol (Ps) of the sperm cell membrane. The permeability parameters were determined at 22, 10, and 0 °C of sperm from 7 Holstein Frisian artificial insemination (AI) bulls, using four ejaculates per bull. A stopped-flow approach was applied to provide temporal resolution sufficient to measure rapid cell volume changes under anisosmotic ...

Supercooling causes very abrupt temperature and osmotic changes and can thus lead to freezing damage. Supercooling can be prevented by seeding, using a sample volume and geometry that allows rapid spreading of the ice throughout the sample. In a split-sample comparison of such samples on the cooling stage of a cryomicroscope and seeded at −5 and −15 °C, respectively, the percentages of membrane-intact sperm and sperm with acrosomes with a ‘normal apical ridge’ (NAR) were 72.5 ± 3.8 and 75.8 ± 2.0 versus ...

We have developed a quantitative description of the osmotic behaviour of cells during freezing without a presupposed value of the cooling rate. Instead, at all times the intracellular supercooling is maximised provided that it does not exceed a predetermined value 'p' (e.g., 2 °C). This should preclude intracellular ice formation, but also ensures that the osmotic gradient and the CPA concentration gradient are limited, as well as the gradient driven transmembrane fluxes of water and CPA. Using the ...
