13. How does the nectar of stomata-free nectaries cross the cuticle?
ABSTRACT In many glandular structures, departure from the cell is only one step in the process of exudate release to the plant surface. Here the set of events that lead nectar to the external environment is presented and discussed mainly for stomata-free nectaries. After being synthesized, the nectar or some of its component needs to be released to the envir

14. Myiasis associated with an invasive ductal carcinoma of the left breast: case study
ABSTRACT Most breast cancers originate in the ductal epithelium and are referred to as invasive ductal carcinoma. In this study we report on the clinical procedures adopted to diagnose myiasis in association with infiltrating metastatic breast carcinoma in a female patient. A 41 years old woman came to the Federal Hospital of Andaraí complaining of intense

15. Outer cell wall structure and the secretion mechanism of colleters of Bathysa nicholsonii K. Schum. (Rubiaceae)
ABSTRACT Secretory structures are formed by many types of plants and are present on numerous different organs. Among the many types of known secretory structures, colleters are predominant on plants of the Rubiaceae. One remarkable characteristic of secretory tissues is the export of exudates; however, the precise mechanism involved in this process is still

16. Influence of temperature, pH and salts on rheological properties of bitter almond gum
Abstract This study focuses on the rheological properties of bitter almond gum (BAG) exudate at different shear rates, concentrations, temperatures, pH, and in the presence of various salts. Rheological data fitted with the Power law model revealed that BAG solutions exhibit non-Newtonian, shear thinning behavior without thixotropic effects at all tested con

17. Exuberant pyoderma gangrenosum in a patient with autoimmune hepatitis
Abstract: Pyoderma gangrenosum is a rare neutrophilic dermatosis, which usually presents as ulcers with erythematous-violaceous undermined edges and a rough base with purulent or sanguinous exudate. It can be primary or associated with an underlying disease. However, rare cases of its association with autoimmune hepatitis have been described in the literatur

18. Experimental Coinfection of Chicken Anemia Virus and Mycoplasma gallisepticum Vaccine Strains in Broiler Chicks
ABSTRACT This study aimed at determining the clinical and pathological effects of the coinfection of young SPF chickens with chicken anemia virus (CAV) and Mycoplasma gallisepticum (MG) vaccine strains. The clinical signs, gross and microscopic lesions were determined after the experimental coinfection broilers with a CAV genotype 1 vaccine strain given intr

19. Assessing the use of frozen pork meat in the manufacture of cooked ham
This study aimed to evaluate the effects of slow (–18 °C) and fast freezing (liquid nitrogen) of pork meat, and the use of exudate released upon thawing, on the physicochemical, color, rheological, microbiological, histological, and sensory characteristics of cooked ham. The meat samples were frozen at –18 °C and thawed after 22 weeks for the productio

20. Alginate dressings for treating pressure ulcers
ABSTRACT BACKGROUND: Pressure ulcers, also known as bedsores, decubitus ulcers and pressure injuries, are localised areas of injury to the skin or the underlying tissue, or both. Dressings are widely used to treat pressure ulcers and there are many options to choose from including alginate dressings. A clear and current overview of current evidence is requ

21. Preconditioning with mono and polyunsaturated fatty acids and low-intensity electrical stimulation. Effects on skin repair in rats
PURPOSE: To evaluate the effects of preconditioning with oils mixes containing ω3/ω6/ω9 associated with micro-currents on skin repair in rats. METHODS: One-hundred and eight Wistar rats randomized into G-1, G-2 and G-3 groups were treated with saline (0.9%), mix 1 (corn+soybean oils) and mix 2 (olive+canola+flaxseed oils), respectively, in a single dose

22. Dermoscopy assisting the diagnosis of mycetoma: case report and literature review
Mycetomas are a chronic skin infection characterized by perilesional edema, formation of sinus tracts, and discharge of purulent or seropurulent exudate containing grains. This report aims to demonstrate the clinical diagnosis (by dermoscopy) of a skin lesion that initially bared no clinical features of a mycetoma.

23. Pork loin two-toning and drip loss in relation to steak cross-section anatomical position, plasma and exudate glucose
Perception of color and its relationship to water holding capacity are important for defining the yield and quality of the pork production process. The aim of this study was to identify the relationship among color measurements taken at various anatomical positions in the cross-sectional surface of pork loin steak, and measurements of fluid exudation and its

24. Streptococcal acute pharyngitis
Acute pharyngitis/tonsillitis, which is characterized by inflammation of the posterior pharynx and tonsils, is a common disease. Several viruses and bacteria can cause acute pharyngitis; however, Streptococcus pyogenes (also known as Lancefield group A β-hemolytic streptococci) is the only agent that requires an etiologic diagnosis and specific treatment.
