BACKGROUND AND PURPOSE Histologic evidence of cortical tubers is pathognomonic of tuberous sclerosis (TS) disease. Cerebellar tubers, however, are uncommonly found. Our objective was to evaluate the prevalence and characteristics of cerebellar tubers in a large series of pediatric patients with TS studied with MR imaging. In particular, their relationship with volume loss and age will be analyz...

The performance of seed tubers harvested from potato plants grown from sprout cutting, stem cutting and conventional seed tubers against PVY and PLRV were investigated. Sprout cutting, stem cutting and conventional seed tubers of variety Diamant were planted and second and third generation seed tubers were harvested. The least incidence of PVY and PLRV was recorded when seed tubers from sprout ...

—In herbivorous birds the processing rate of food is constrained by gizzard capacity. To enhance digestive processes, many species ingest grit to grind the food. Grit ingestion, however, may further limit the capacity of the gizzard. Graylag Geese (Anser anser) wintering in SW Spain fed mainly on Alkali Bulrush (Scirpus maritimus) tubers, showing a preference for small tubers. This preference m...

Sir, I read with interest the case report by Al-Futaisi et al. published in the November 2016 issue of SQUMJ which described three children with both autism spectrum disorders (ASDs) and tuberous sclerosis complex (TSC).1 In case one, computed tomography (CT) of the brain appeared normal. In case two, a magnetic resonance imaging (MRI) scan of the brain revealed nodular heterotopias and tubers ...

Sucrose synthase (SuSy) is a highly regulated cytosolic enzyme that catalyzes the conversion of sucrose and a nucleoside diphosphate into the corresponding nucleoside diphosphate glucose and fructose. To determine the impact of SuSy activity in starch metabolism and yield in potato (Solanum tuberosum L.) tubers we measured sugar levels and enzyme activities in tubers of SuSy-overexpressing pota...

This paper presents the pathological and biochemical changes among the freshly harvested potato tubers, freshly harvested infected tubers, cold stored healthy tubers and cold stored rotted tubers. In the study, fresh and infected samples of potato tubers were taken from the farmer’s field to understand the pathological and biochemical diversity. After the examination, potatoes were kept in the ...

OBJECTIVE To evaluate whether diffusion tensor imaging (DTI) can predict epileptogenic tubers by measuring apparent diffusion coefficient (ADC), fractional anisotropy, axial diffusivity, and radial diffusivity in both tubers and perituberal tissue in pediatric patients with tuberous sclerosis complex (TSC) undergoing epilepsy surgery. METHODS We retrospectively selected 23 consecutive patient...

Cyanide-resistant O(2) consumption can be stimulated by either treating whole white potato tubers (Norchip) with ethylene, in the presence of 100% O(2), or aging slices obtained from untreated potato tubers. A comparison of alternative pathway activity elicited by either treatment was undertaken. The proportion of electrons flowing through the alternative path in the presence of intermediate co...

Tubers of Solanum tuberosum L. var. Russet Burbank, Kennebec, and Targhee were stored at 95% relative humidity and at 1.7, 4.4, 5.8, 7.2 or 10 C. Rates of O(2) consumption were measured periodically by removing individual tubers from storage, excising discs of pith parenchyma tissue, and incubating the discs in a Gilson respirometer at 30 C. With all three varieties, data suggest a greater invo...
