Recurrent drought and late blight disease are the major factors limiting potato productivity in the northwest Ethiopian highlands. Incorporating drought tolerance and late blight resistance in the same genotypes will enable the development of cultivars with high and stable yield potential under erratic rainfall conditions. The objectives of this study were to assess combining ability effects an...

The pathogenesis of histamine-induced coronary spasm was examined angiographically and morphometrically in Göttingen miniature pigs. In five of 36 consecutive pigs that were 4 to 5 months of age, coronary spasm was provoked by the intracoronary administration of histamine, and the left coronary arteries were examined histologically without endothelial denudation (group 1). Endothelial balloon d...

The capillary loop consists of an arterial or afferent branch and a venous or efferent branch. The main parameters to be evaluated are: length, diameter, density, venous plexus and morphological abnormalities. These elements should be evaluated in the distal row or near the nailfold. The normal number of capillaries per millimeter is from seven to twelve arranged in an inverted U-shape (Figure 1).

Tuber pseudoexcavatum, Tuber sinoaestivum, and Tuber indicum are the 3 most important truffles growing in southeast China; however, their cultivation is still inefficient owing to the lack of understanding regarding the composition and function of the bacterial and fungal communities from the soils around the fruit bodies and the ectomycorrhiza of these truffles. The aim of this study was to di...

Black truffles that morphologically resemble Tuber indicum have been known to occur in Japan since 1979. Our previous studies showed that there are two phylotypes of these truffles, both of which fell into the T. indicum complex (hereinafter "Tuber sp. 6" and "Tuber sp. 7"). However, their taxonomic treatment is still unclear. In this study, we conducted morphological and phylogenetic analyses ...

doi: 10.1111/j.1399-3054.2006.00741.x Calcium is believed to be transported with water in the xylem. Consistent with this proposal, low-transpiring organs such as potato Solanum tuberosum tubers are known to suffer from calcium deficiency. Although roots on tubers and stolons have been shown to supply water to tubers, there is no direct evidence for the calcium transport pathway to tubers. Both...

BACKGROUND Patients with human immunodeficiency virus (HIV) infection and a history of Pneumocystis carinii pneumonia are at high risk for relapse if they are not given secondary prophylaxis. Whether secondary prophylaxis against P. carinii pneumonia can be safely discontinued in patients who have a response to highly active antiretroviral therapy is not known. METHODS We analyzed episodes of...

A 10-month-old female, Wire-haired Pointing Griffon dog had a hamartoma of the hypothalamus. Episodes of sudden flaccid collapse had increased in frequency and duration for 7 months. Cerebrospinal fluid pressure was normal. A flat, pedunculated mass, 2.5 X 3.0 X 0.9 cm, covered the brain stem between the pituitary gland and pons. Its 1.2-cm-diameter connection to the hypothalamus obliterated th...

Abstract Yellow nutsedge is one of the most widely distributed and troublesome weeds in world. Field greenhouse studies were conducted to optimize strategies for increased yellow control turfgrass with halosulfuron sulfentrazone. In field study perennial ryegrass mixture, single or sequential applications (3 wk after initial) sulfentrazone made on June 3, 23, July 15, August 5 2013, 2014, 2015,...
