had been no traction on the cord, and this is probably correct, as the more popular method of aiding the third stage is to stuff a tress of the mother's hair into her mouth, so that the resulting vomiting will cause expulsion of the placenta. As far as the history could be ascertained, a protuberance had appeared shortly after birth, and during the day had gradually increased in size, but the h...

Antimicrobial susceptibilities of Staphylococcus aureus strains can be determined accurately by using isolates from mannitol salt agar, and yellow isolates on mannitol salt agar at quantities of >1+ can be reported as S. aureus. These methods decrease the time to identification/antimicrobial susceptibility testing of S. aureus and decrease costs through eliminating additional testing.

The progressive geometric changes that occur in swelling of corn starch granules during heating throughout the range of gelatinization (63-72°C) and at higher temperatures when substantial amount s o f soluble starch are released from the granule were observed by scanning electron micro s copy (SEM). Corn starch granules beg in to swell radially, then undergo radial contraction and random tange...

Low fat (LF) cheddar cheese develops flavor during aging uncharacteristic of full fat (FF) cheese, such as rosey and burnt/brothy flavors and bitter taste. Our objective was to determine if this is a function of differences in salt-in-moisture (S/M) content. Full fat and LF curd was made (in triplicate) using 700 kg of milk and salted to produce cheese with S/M typical of LF cheese. Half the cu...

BACKGROUND Chronic hypertension leads to cardiac hypertrophy, heart failure, and premature death. Little is known about the impact of dietary macronutrient composition on hypertension-induced cardiac hypertrophy and mortality. We investigated the effects of consuming either a high complex carbohydrate diet, a high simple sugar diet, or a high fat diet on cardiac hypertrophy and mortality in hyp...

A hydroponic experiment was carried out to compare root anatomy and hydraulic conductivity of four barley cultivars including Valfajr, Karoon, Afzal and Zarjo under salt stress conditions. The results showed that under salt stress, the minimum diameter of vessels was observed in the peripheral metaxylem of seminal roots of Valfajr cultivar and in adventitious roots; Karoon with 19±3 µm had maxi...

Phaseolus vulgaris represents a great source of nutrit io n fo r millions of people, and is the second most important legume crop, after soybean. Assessment of environmental contamination on e cology (plant) at molecular and population levels is important in risk quantification and remediation s tud y . Heavy metal toxicity in plants is to induce o xidative s tress linked to oxidation of protei...

The effect of salt concentration on catalysis by ribonuclease A (RNase A) has been reexamined. At low salt concentration, the enzyme is inhibited by low-level contaminants in common buffers. When an uncontaminated buffer system is used or H12A RNase A, an inactive variant, is added to absorb inhibitory contaminants, enzymatic activity is manifested fully at low salt concentration. Catalysis by ...
