Production of very-high-amylose potato starch by inhibition of SBE A and B.

High-amylose starch is in great demand by the starch industry for its unique functional properties. However, very few high-amylose crop varieties are commercially available. In this paper we describe the generation of very-high-amylose potato starch by genetic modification. We achieved this by simultaneously inhibiting two isoforms of starch branching enzyme to below 1% of the wild-type activities. Starch granule morphology and composition were noticeably altered. Normal, high-molecular-weight amylopectin was absent, whereas the amylose content was increased to levels comparable to the highest commercially available maize starches. In addition, the phosphorus content of the starch was increased more than fivefold. This unique starch, with its high amylose, low amylopectin, and high phosphorus levels, offers novel properties for food and industrial applications.

Gastric teratoma in infants--a report of two cases.

Gastric teratoma is an exceeding rare lesion seen most often in male infants. Two cases of gastric teratoma, the first in a three and half month male, and the second in a one year old male child are reported. In the first case, the tumour was more solid, while in the second case it was a solid-cystic mass. These two cases represent the additions to the few, limited, known gastric teratomas reported in the world literature.

Congenital diaphragmatic hernia: a retrospective autopsy study.

Congenital diaphragmatic hernia is one of the acute pediatric surgical emergencies and an important cause of perinatal mortality. Its incidence varies from 1 in 2000 to 1 in 5000 live-births, with a greater incidence in stillbirths and abortions. Non-operative mortality is generally reported as 100% and early diagnosis is imperative. A retrospective study of all infant and neonatal autopsies done during last 30 years (1960 to 1989) was conducted. Ten cases of congenital diaphragmatic hernia were encountered among 588 autopsies and its incidence was 1.7% of all infant and neonatal autopsies, dying due to varying causes. The male:female ratio was 7:3, while maternal factors showed no consistent relationship. All cases had left-sided posterolateral diaphragmatic defects. Dyspnea, cyanosis and dextrocardia was the classical triad present in more than 50% cases. The commonest herniated contents were the small intestinal loops and the left lobe of liver. Associated congenital multiple anomalies related to neural axis, skull, vertebral column and cardiovascular system were noted in 30% cases and were major contributory factors for perinatal mortality.
