In this study, a first record on interaction of insect with fern species has been presented from Malaysia. Molecular identification of cytochrome oxidase I gene (COI) has revealed the Herpetogramma platycapna (Meyrick) is the gregarious pest of Angiopteris evecta (G. Forst.) Hoffm. The pest species also has been reconfirmed based on morphological c...

This paper reported molecular data on insect pests of commercial crops in Peninsular Malaysia. Fifteen insect pests (Metisa plana, Calliteara horsefeldii, Cotesia vestalis, Bactrocera papayae, Bactrocera carambolae, Bactrocera latifrons, Conopomorpha cramella, Sesamia inferens, Chilo polychrysa, Rhynchophorus vulneratus, and Rhynchophorus ferrugine...

Spodoptera exigua (Lepidoptera: Noctuidea) is a polyphagous pest that attacks many important agricultural crops. Identifying an insect specimen is a crucial step in entomology. This study demonstrated a molecular method to identify the species of pest and its parasitoid in the case of a lack of a morphological identification key. To facilitate the...

Thyroid dysfunction complicates the metabolic derangement observed in Diabetes Mellitus (DM). It is necessary to recognize and treat it when present in order to achieve stability of metabolic control in these patients. The prevalence of thyroid dysfunction in type-2 diabetics in our environment is not known. This study was therefore designed to det...

Metabolic syndrome is the commonest controllable precursor of cardiovascular and end stage renal diseases. While central obesity is recognized universally as its strongest component, there is the need for an accurate and affordable tool to screen for the presence of metabolic syndrome in every community. The easiest and cheapest measures of obesity...

Using strain-guaged duplicate maxillary dentures, the deformation patterns and magnitude of functional strain were studied on five complete denture wearing subjects who had varying amounts of soft mobile tissue over their maxillary edentulous alveolar ridge so called flabby ridges. The thickness of mobile tissue--expressed as depth--was measured by...

Using strain-gauged maxillary complete dentures, the effects of the surgical removal of soft mobile tissue over the maxillary edentulous alveolar ridges--flabby ridges--on the deformation pattern and magnitude of functional strain were studied in five subjects. The results showed that a 20-90% reduction in denture deformation had taken place after...

Summary— Emphysematous pyelonephritis in patients with diabetes mellitus is increasingly recognised as a disease requiring urgent and aggressive treatment. We present 3 cases of emphysematous pyelonephritis; 1 patient required percutaneous nephrostomy followed by nephroureterectomy but the other 2 were successfully managed with antibiotics and cont...

A modified cyclic reactor has been used to investigate the mechanism of ethylene epoxidation on a high activity silver catalyst and on a commercial silver catalyst. This periodic pulse reactor allows on line G.C. analysis of the reactor effluent at any chosen time interval from the beginning of the cycle. Three kinds of oxygen species on the silver...

A high activity supported silver catalyst has been prepared and used to investigate steady state kinetics of ethylene epoxidation at low temperature (180 to 210°C), with and without chlorine inhibition. Langmuir-Hinshelwood rate expressions interpret satisfactorily the observed low or negative partial orders. But, as previously proven by unsteady s...

3 patterns of incidence of renal calculi in children can be recognized: endemic, ammonium acid urate bladder calculi, for example in the Far East; infective, magnesium ammonium phosphate upper tract calculi associated with Proteus infection in Europe; rare metabolic disorders associated with nephrocalcinosis or stone formation, as in the USA. In Br...

The relation between the true plasma creatinine concentration (Pc) and the glomerular filtration rate corrected for body surface area (GFR/SA) was investigated in 108 individuals, and the following formula was derived: GFR/SA (ml/min per 1-73m2SA) = 0-43 Ht (cm)/Pc (mg/100 ml). This formula was tested in a second group of 83 children, and its accur...

152 children with urinary calculi were treated in the United Kingdom and Eire in the years 1972 and 1973. There was a marked male preponderance particularly evident in early life. In 124 children the urine was infected on admission to hospital; in 87, particularly the younger children, this was with the Proteus species. Awareness of the relationshi...

After relief of obstructive nephropathy urinary sodium excretion rose in 39 of 50 children to a mean in the whole group of 59% above preoperative levels. There was a significant positive correlation between the increase in sodium excretion in the first 24 hours after operation and the increase in GFR at 1 week. The data are compatible with the hypo...

Urine calcium excretion in healthy children was 2·38±0·66 (SD; no. = 52) mg/kg per 24 hr and urinary magnesium excretion was 2·82±0·79 (SD; no. = 23). The 24-hour urine calcium excretion could be predicted with reasonable confidence from the calcium/creatinine concentration ratio of the second urine specimen passed in the morning. In this specimen...

Of nine children with presacral teratomas four under the age of 6 mo, had benign tumors and are alive and well after surgery. Of five children older than 6 mo with malignant tumors, four were dead within 1 yr in spite of treatment. From these cases it is clear that survival of these infants is related to the age at which the diagnosis is discovered...

120 children with urinary calculi were treated between 1966 and 1971. 75% were male, and the median age of diagnosis was 3 years. In 34 there were associated urological abnormalities and in 8 a metabolic cause of calculi was identified. 12 of 67 children had hypercalciuria. In 95 children the urine was infected on admission to hospital; in 76, part...

Two uremic infants with profound hypomagnesemia had convulsions that were controlled only by parenteral magnesium therapy. Plasma magnesium levels were estimated in 11 subsequent infants with acute or acute-on-choronic renal failure and were related to the plasma levels of calcium, phosphate, and urea. Plasma magnesium levels at or below 0.9 mg. pe...
