Munro (1951) showed that nitrogen retention in rats is reduced when calorie intake is restricted. Although an adaptive process to continued moderate calorie restriction was demonstrated with dogs (Rosenthal & Allison, 1 9 5 1 ) and man (Drury, Vaughan & Hannon, 1959), a linear relationship between N balance and the amount of carbohydrate given along with the protein of the diet was observed in ...

Maxillary sinus harbours many pathological lesions. Many of those presents as a sinonasal mass and are rarely symptomatic. These masses are usually an antral polyp, mucoceles or mucous retention cysts. Odontogenic keratocyst, a benign odontogenic lesion presenting within the maxillary sinus is a rare entity. We present a case of odontogenic keratocyst of the maxillary sinus in a 35 years old fe...

Published data suggest that hydrogenosomes, organelles found in diverse anaerobic eukaryotes that make energy and hydrogen, were once mitochondria. As hydrogenosomes generally lack a genome, the conversion is probably one way. The sources of the key hydrogenosomal enzymes, pyruvate : ferredoxin oxidoreductase (PFO) and hydrogenase, are not resolved by current phylogenetic analyses, but it is li...

Saturated sand-packed column experiments were conducted to investigate the influence of physicochemical factors on the transport and retention of surfactant stabilized silver nanoparticles (AgNPs). The normalized concentration in breakthrough curves (BTCs) of AgNPs increased with a decrease in solution ionic strength (IS), and an increase in water velocity, sand grain size, and input concentrat...

PURPOSE To report a case of primary conjunctival epithelial inclusion cyst with atypical manifestation. METHODS A 66-year-old woman presented with a yellowish, subconjunctival mass extending from the corneal limbus to the medial canthus in the left eye. Clinical, radiological and histological assays were performed. RESULTS The mass was well-delineated, and the overlying conjunctiva was norm...

Zinner's syndrome is a rare condition that can be challenging to diagnose and manage. Limited knowledge about its natural history optimal treatment further complicates matters. To shed more light on this condition, we present case series of three patients with syndrome, highlighting their clinical presentations, diagnostic workup, options. Our first patient was 16-year-old male left epididymo-o...

Parathyroid cysts were produced in rats by excessive doses of dihydrotachysterol. (DHT) and calcium acetate. Although overdoses of each DHT, calcium or their combination are believed to suppress the activity of the parathyroid cell, the present electron microscopic observation showed signs of enhanced protein synthesis and secretion of the cells in all stages of cyst formation. It seems reasona...

1. The experimental barley samples included 4 hulled and one hull-less low-phytate barley cultivars and two commercial barley varieties as controls. 2. The diets were provided in meal form, with the experimental barley samples constituting the cereal source. Two additional treatments were added for each of the control varieties in which intermediate and recommended levels of phosphorus were pro...
