Prevalence of neoplasia diagnosed in dogs at the veterinary hospital at eduardo mondlane university, mozambique

A retrospective study of tumors in dogs was carried out in the School Veterinary Hospital (HVE), Eduardo Mondlane University, Mozambique, between January 2004 and January 2009. Data from clinical-surgical records of tumor samples surgically removed, necropsy and cytological exams were used and sent for histopathology exams. During the study 210 tumors and about 27 different types of tumors were identified. Skin tumors (61.0%) were the most frequent, followed by mammary gland tumors (27.60%), reproductive system tumors (11.90%) and bone system tumors. The mammary gland tumors were observed only in females, with high prevalence in bitches which were not spayed or spayed after two years old. It was concluded that the neoplasia prevalence increase was correlated to the higher longevity of dogs, and breed also contributed for the development of determined tumors due to high incidence of mastocitomas in Boxer and German Shepherd breeds. The 100 % incidence of mammary gland neoplasia in females confirmed the higher predisposition for mammary gland neoplasia in females.

Influence of potassium and sodium nutrition on leaf area components in Eucalyptus grandis trees

Background and Aims: Recent studies showed a positive tree response to Na addition in K-depleted tropical soils. Our study aimed to gain insight into the effects of K and Na fertilizations on leaf area components for a widely planted tree species. Methods: Leaf expansion rates, as well as nutrient, polyol and soluble sugar concentrations, were measured from emergence to abscission of tagged leaves in 1-year-old Eucalyptus grandis plantations. Leaf cell size and water status parameters were compared 1 and 2 months after leaf emergence in plots with KCl application (+K), NaCl application (+Na) and control plots (C). Results: K and Na applications enhanced tree leaf area by increasing both leaf longevity and the mean area of individual leaves. Higher cell turgor in treatments +K and +Na than in the C treatment resulting from higher concentrations of osmotica contributed to increasing both palisade cell diameters and the size of fully expanded leaves. Conclusions: Intermediate total tree leaf area in treatment +Na compared to treatments C and +K might result from the capacity of Na to substitute K in osmoregulatory functions, whereas it seemed unable to accomplish other important K functions that contribute to delaying leaf senescence. © 2013 Springer Science+Business Media Dordrecht.

Effect of Low-Temperature Storage on Diaeretiella rapae (McIntosh) (Hymenoptera: Braconidae)

We evaluated the effects of constant low-temperature storage on Diaeretiella rapae (McIntosh) (Braconidae, Aphidiinae). Diaeretiella rapae mummies were stored at 5 ± 1°C for 0-36 days. The percentage of D. rapae emergence varied (100-83%) after 0-32 days of storage. After 32 days, emergence reduced to 55%. According to our Probit analysis, 50% mortality (LT50) of the population of D. rapae was reached after 40 days of storage at 5°C. Storage for up to 32 days did not negatively affect emergence and survival. Cold exposure of D. rapae for 36 days did not influence morphological malformations, sex ratio, and emergence of the F1 generation. After 4-36 days of storage, D. rapae showed a gradual decrease in emergence, longevity, reproductive capacity, and F1 sex ratio. Diaeretiella rapae can be stored for up to 24 days at 5°C, at which time the percentage of parasitism and the F1 sex ratio remain above 38% and at 0.50, respectively. © 2013 Sociedade Entomológica do Brasil.
