Understanding the Intricate Web of Phytohormone Signalling in Modulating Root System Architecture.

Root system architecture (RSA) is an important developmental and agronomic trait that is regulated by various physical factors such as nutrients, water, microbes, gravity, and soil compaction as well as hormone-mediated pathways. Phytohormones act as internal mediators between soil and RSA to influence various events of root development, starting from organogenesis to the formation of higher order lateral roots (LRs) through diverse mechanisms. Apart from interaction with the external cues, root development also relies on the complex web of interaction among phytohormones to exhibit synergistic or antagonistic effects to improve crop performance.

Echocardiographic Changes in Cases of Intermittent Acute Porphyria.

Intermittent acute porphyria (IAP) is an inborn metabolic disorder of biosynthesis of haeme, characterized by increased excretion of porphyrin or porphyrin precursor in urine and clinically by gastrointestinal, neuro-psychiatric and cardiovascular manifestations. Significant observations were made on echocardiographic examination of 25 IAP patients in our study. Significant decrease in ejection fraction (48.

A preliminary study of glycosylation of hair in diabetes mellitus.

Glycosylation of hair was studied in 30 diabetic (15 IDDM and 15 NIDDM) patients and in 30 age and sex matched healthy non-diabetic subjects. A positive correlation occurs between glycosylation of proximal portion of hair and the simultaneously measured glycosylated haemoglobin. The hair glycosylation remains stable along the length of hair from scalp to tip in normal subjects and suggests that a sufficiently long hair sample may offer a long term record of degree of hyperglycaemia.

Alcohol and Indian porphyrics.

The role of alcohol as the precipitating factor in the induction of acute attacks of acute intermittent porphyria was studied in an Indian population. Thirty-four teetotal patients with acute intermittent porphyria, in remission, were given 60 ml of 30% ethanol. Except for two patients, all had negative Watson-Schwartz tests prior to the alcohol.

Ehlers-danlos Syndrome in Four Generations.

Thirteen cases of Ehlers-Danlos syndrome are being reported from a twentyfive member family. All had type 11 (mitis) variety of Ehlers-danlos syndrome with autosomal dominant transmission.

Induction of pseudo-pregnancy in Saccobranchus fossilis and cytomorphological assay of anomalies.

Pseudo-pregnancy was induced in S. fossilis fish with Progynon and the consequences were studied with special emphasis to the assay of anomalies, on the cytomorphological level. Anomalies included profuse clumping, precocious despiralization and stickiness.
