Slivka, A.; Vallini, D.; Hwang, T.; Saverance, M.; Booth, K.; Murphy, D.BACKGROUND: Epidemiological studies suggest that raised plasma concentrations of total homocysteine might be a risk factor for major vascular events. Whether lowering total homocysteine with B vitamins prevents major vascular events in patients with previous stroke or transient ischaemic attack is unknown. We aimed to assess whether the addition of once-daily supplements of B vitamins to usual medical care would lower total homocysteine and reduce the combined incidence of non-fatal stroke, non-fatal myocardial infarction, and death attributable to vascular causes in patients with recent stroke or transient ischaemic attack of the brain or eye. METHODS: In this randomised, double-blind, parallel, placebo-controlled trial, we assigned patients with recent stroke or transient ischaemic attack (within the past 7 months) from 123 medical centres in 20 countries to receive one tablet daily of placebo or B vitamins (2 mg folic acid, 25 mg vitamin B6, and 0.5 mg vitamin B12). Patients were randomly allocated by means of a central 24-h telephone service or an interactive website, and allocation was by use of random permuted blocks stratified by hospital. Participants, clinicians, carers, and investigators who assessed outcomes were masked to the assigned intervention. The primary endpoint was the composite of stroke, myocardial infarction, or vascular death. All patients randomly allocated to a group were included in the analysis of the primary endpoint. This trial is registered with ClinicalTrials.gov, NCT00097669, and Current Controlled Trials, ISRCTN74743444. FINDINGS: Between Nov 19, 1998, and Dec 31, 2008, 8164 patients were randomly assigned to receive B vitamins (n=4089) or placebo (n=4075). Patients were followed up for a median duration of 3.4 years (IQR 2.0-5.5). 616 (15%) patients assigned to B vitamins and 678 (17%) assigned to placebo reached the primary endpoint (risk ratio [RR] 0.91, 95% CI 0.82 to 1.00, p=0.05; absolute risk reduction 1.56%, -0.01 to 3.16). There were no unexpected serious adverse reactions and no significant differences in common adverse effects between the treatment groups. INTERPRETATION: Daily administration of folic acid, vitamin B6, and vitamin B12 to patients with recent stroke or transient ischaemic attack was safe but did not seem to be more effective than placebo in reducing the incidence of major vascular events. These results do not support the use of B vitamins to prevent recurrent stroke. The results of ongoing trials and an individual patient data meta-analysis will add statistical power and precision to present estimates of the effect of B vitamins.

It is a byword for strength and wisdom. They have been depicted in Indian architecture as temple bearers. This paper will discuss the depiction of elephants by Edwin Landseer Lutyens in the architecture of Rashtrapati Bhavan or President House of India, which was known as Government House or Viceroy House during British Rule. The architecture of this place is very interesting and fascinating and is a combination of Indo-European styles. Many animal figurines have been introduced by Lutyens in the architecture of Rashtrapati Bhavan but most prominently he had introduced elephants in various locations across the place. Most of the elephant figurines have been carved in stone on the main entrance of President House and while they seem to guard the entrance, their importance extends far more than their present-day use as working animals. Lutyens understood their importance in Indian mythology. On the north and south sunken road entrances also Lutyens had introduced huge elegantly carved elephants in red sand stone, the canopies above them seem like howddahs or seats. This can be compared with the elephant rows carrying the world mountain Meru at the Kailasha temple of Ellora. The elephant also frequently appears in Lutyen’s drawings and sketches, and he transformed its benign solidity most effectively in his architecture. The State Banquet Hall of President House also has elephant trunks depicted in wooden panelling all over on the upper sides. Other examples are the procession paintings on the side walls of Ashoka Hall which depict the King’s procession going on elephants, horses and camels. The paintings of Ashoka Hall known as State Ball Room in the Vice Regal period is adorned by these paintings in fresco style which were done by an Italian painter, Collonello with the help of twelve Indian painters, probably inspired by the fact that the elephants not only guard the palace as symbols of strength but they are also a regular fixture in all great processions of India whether religious or political. Another interesting example is the Pergola or the shaded device made of red sandstone used in the Mughal Garden of President House by Lutyens. In the structure he created a statically balanced system of short beams that were procured in balance by decorated stone weights, which resemble the trunk of elephants. Thus my paper will take into account different aspects of the depiction of elephants by Lutyens in the architecture of President House. The paper will also take into account the use of elephants in the architecture of North Block and South Block located exactly on the north and south sides of President House designed by Lutyen’s partner Herbert Baker.Item Depiction of Elephants in the Architecture of Rashtrapati Bhavan by Lutyens(Centre for Asian Studies, University of Kelaniya, Sri Lanka, 2016) Gupta, R.Item Multi-temporal and multi-resolution satellite data for urban growth monitoring(University of Kelaniya, 2008) Gupta, R.
