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.

Backward Anaphors.
(The Third International Conference on Linguistics in Sri Lanka, ICLSL 2017. Department of Linguistics, University of Kelaniya, Sri Lanka., 2017) Singh, H.
This paper stipulates Referring expressions (with the special reference of „Backwardness‟ of such identity relations) in Punjabi. In natural languages, such expressions are in anaphoric nature and linguistically also specified with all possible categories (e.g. nominal, pronominal, verbal etc.). In general, anaphors are basically lexical categories that are unmarked and explicit and implicit with various manners in the natural language. In GB framework, it is mostly discussed with principles of (A) as dependent in the same local domain of the sentence, in the form of lexical anaphors. But here, we check its counter part as cataphora (he=John) in such relation and will discuss with some instances in ILCI Punjabi corpus. In fact, the study of anaphors is computationally a new research area in Punjabi. From the grammar point of view, it is basically encountered as pronominals in most of the cases and somehow it can be managed with Government and Binding framework (1981, 82). But still, there is no specific algorithm, which can attract machine-learning process in Punjabi. In this paper, the main concern is to prepare provisional algorithm platform for Punjabi through the discussion of cataphora or may be backward anaphora in 1,000 sentences of ILCI Punjabi corpus. We manually search around 1,000 sentences and find some instances of backward anaphors. We analysis them according to Lakoff (1968) findings as backwardness for English and collect Punjabi instances on the basis of such inquiry. As mentioned in the previous sections, it is not the fully-grown area of research in Punjabi. It is the initial endeavor where we are trying to use the instances of cataphora for computational purposes. By following previous proposals of cataphora, we discuss POS tagged Punjabi files and then separate cataphoric instances. We propose some steps as an instruction in the form of cyclic manner of searching first some possible referring expressions as PR_PRP and then move on to another kinds of DM_DMD categories. It may assume that the cyclic conditions may bring positive results with probably some changes in future. It also accepts that the cases like doubling; large group of referent choice may also be discussed surely when we put such instructions in the system form.
Diabetes and Alzheimer's disease: Can tea phytochemicals play a role in prevention?
(IOS Press, 2017) Binosha, F.W.M.A.D.; Somaratne, G.; Williams, S.; Goozee, K.G.; Singh, H.; Martins, R.N.
Dementia and diabetes mellitus are prevalent disorders in the elderly population. While recognized as two distinct diseases, diabetes has more recently recognized as a significant contributor to risk for developing dementia, and some studies make reference to type 3 diabetes, a condition resulting from insulin resistance in the brain. Alzheimer's disease, the most common form of dementia, and diabetes, interestingly, share underlying pathological processes, commonality in risk factors, and, importantly, pathways for intervention. Tea has been suggested to possess potent antioxidant properties. It is rich in phytochemicals including, flavonoids, tannins, caffeine, polyphenols, boheic acid, theophylline, theobromine, anthocyanins, gallic acid, and finally epigallocatechin-3-gallate, which is considered to be the most potent active ingredient. Flavonoid phytochemicals, known as catechins, within tea offer potential benefits for reducing the risk of diabetes and Alzheimer's disease by targeting common risk factors, including obesity, hyperlipidemia, hypertension, cardiovascular disease, and stroke. Studies also show that catechins may prevent the formation of amyloid-β plaques and enhance cognitive functions, and thus may be useful in treating patients who have Alzheimer's disease or dementia. Furthermore, other phytochemicals found within tea offer important antioxidant properties along with innate properties capable of modulating intracellular neuronal signal transduction pathways and mitochondrial function.
Grammaticalisation of the Verb ‘ləɡ’ in Punjabi, Hindi and Bangla Languages
(Department of Linguistics, University of Kelaniya, Sri Lanka, 2016) Singh, H.
This paper specifies some aspects of the grammaticalisation process by verifying three parallel languages namely Punjabi, Hindi and Bangla for primary data. The whole study is divided into two kinds of initial observations related to the polysemous verb „ləɡ‟. In Punjabi, the verb „ləɡ‟ has various interpretations (of attend, give, use etc.) which are directly related to the subject matter of knowing the grammaticalisation phenomena in languages. However, these interpretations of one language become more visible and useful in the attempt of locating similar or dissimilar results of such verbs in other languages. With this as the purpose of the study, Punjabi is selected as the source language. Hindi and Bangla can easily be marked as semantic bleaching cases among these three languages. By and large, the investigation starts with a study of the occurrence of the verb „ləɡ‟ in V1 and V2 positions, where both similarities and dissimilarities come out straightforwardly. Semantic range of the verb „ləɡ‟ was also noticed where Bangla gives some results different from the other two languages. Other cases like „de-categorisation‟ can be included in the future work with identifying more closeness among the above three languages.
Issues and Concerns of Pesticide Use in Agriculture: Exploring Facts from the Malwa Region of Indian Punjab
(International Conference on Applied Social Statistics (ICASS) - 2019, Department of Social Statistics, Faculty of Social Sciences, University of Kelaniya, Sri Lanka, 2019) Kaur, S.; Singh, K.; Singh, H.
The Malwa region of Indian Punjab face a lot of environment and health issues due to the hazards, excessive, and unsafe use of pesticides, fertilizers, and poor groundwater quality. Cotton crop failure owing to white fly attack in Malwa region of Punjab in 2015 has proved environmental and climate changes have affected cropping pattern adversely that further leads to economic crisis of agrarian community.
