Palai, SK;Rout, Gyana Ranjan;
Horticultura Brasileira , 2011, DOI: 10.1590/S0102-05362011000400029
Abstract: chrysanthemum is the important cut flower after rose among the ornamental plants traded in the global flower market. it is propagated vegetatively and also has a strong sporophytic self-incompatibility system as shown by all members of asteraceae family. morphologically, the petal numbers and flower colours present maximum variation when compared to existing varieties. twenty inter simple sequence repeat primers were used to detect the new variety of chrysanthemum developed through spontaneous sporting. the results indicate that the rate of polymorphism showed significant differences as compared to other existing varieties. the average number of amplification products per primer was eight. the size of issr amplified fragments varied from 0.25 - 2.4 kbp. therefore, issr marker is a useful technique for the rapid and easy assessment of genetic variation among the variants. morphological traits of new variants showed variation as compared to other parents. the 1st flower bud appearance and the height of 1st bud of the variant were less as compared to original mother variety. the new variants can be propagated in large scale commercially through in vitro technique.
Fractal and Mathematical Morphology in Intricate Comparison between Tertiary Protein Structures
Ranjeet Kumar Rout,Pabitra Pal Choudhury,B. S. Daya Sagar,Sk. Sarif Hassan
Computer Science , 2013,
Abstract: Intricate comparison between two given tertiary structures of proteins is as important as the comparison of their functions. Several algorithms have been devised to compute the similarity and dissimilarity among protein structures. But, these algorithms compare protein structures by structural alignment of the protein backbones which are usually unable to determine precise differences. In this paper, an attempt has been made to compute the similarities and dissimilarities among 3D protein structures using the fundamental mathematical morphology operations and fractal geometry which can resolve the problem of real differences. In doing so, two techniques are being used here in determining the superficial structural (global similarity) and local similarity in atomic level of the protein molecules. This intricate structural difference would provide insight to Biologists to understand the protein structures and their functions more precisely.
Phylogenic Study of Twelve Species of Phyllanthus Originated from India through Molecular Markers for Conservation  [PDF]
Gyana Ranjan Rout, Subhashree Aparajita
American Journal of Plant Sciences (AJPS) , 2010, DOI: 10.4236/ajps.2010.11005
Abstract: The objective of the study was to characterize the germplasm for identification and phylogeny study for conservation. Identification and characterization of germplasm is an important link between the conservation and utilization of plant genetic resources. The present investigation was undertaken to draw the phylogenetic relationship between twelve species from India belonging to genus Phyllanthus with the help of molecular markers. In total, 259 marker loci were assessed, out of which 249 were polymorphic revealing 96.13% polymorphism. Nei’s similarity index varies from 0.23 to 0.76 for RAPD and 0.26 to 0.81 for ISSR marker systems. Cluster analysis by unweighted pair group method (UPGMA) of Dice coefficient of similarity generated dendogram with more or less similar topology for both the analysis that gave a better reflection of diversity and affinities between the species. The phylogenetic tree obtained from both RAPD and ISSR marker has divided the 12 species in two groups: group I consisting of only one species Phyllanthus angustifolius and the group II with the rest 11 species. This molecular result is comparable to notable morphological characteristics. The present study revealed the distant variation within the species of Phyllanthus. This investigation will help for identification and conservation of Phyllanthus species.
Agromorphological and Molecular Characterization of Sesamum indicum L.—An Oil Seed Crop  [PDF]

American Journal of Plant Sciences (AJPS) , 2016, DOI: 10.4236/ajps.2016.717210
Abstract: Sesamum indicum L. (family: Pedaliaceae) is an economically important oil seed crop grown in tropical and sub-tropical countries. It is widely used in food, nutraceutical, pharmaceutical industries. Sesamum is widely distributed in all the climatic stages and great diversity. The exploration of genetic diversity is a pre-requisite for genome organization in the landraces and the related domesticated ones. Agromorphological and molecular markers were used to assess the identification of 33 Sesamum genotypes and determination of the genetic relationships among these genotypes. Out of 30 Inter-Simple Sequence Repeat (ISSR) primers tested, 18 primers produced 114 detectable fragments, of which 97 (85.08%) were polymorphic across the varieties. Molecular profiling could be solely used for their identification of genotypes. Genetic relationships among these genotypes were evaluated by generating a similarity matrix based on the Jacard’s coefficient and the Unweighted Pair Group Method with Arithmetic Average (UPGMA) dendogram. The results showed a clear cut separation of the 33 genotypes and were in broad agreement with the morphology. Both molecular and morphological markers will be useful for preservation of the germplasm as well as breeding program.
IMPORTANCE OF DIET AND DIETARY INFLUENCES ON HEALTH EFFECTS IN SCHOOL AND COLLEGE STUDENTS: A SERIOUS AND GROWING GLOBAL PROBLEM
Rout Susanta Kumar,Rout Bikram Keshari
International Research Journal of Pharmacy , 2011,
Abstract: To develop to their optimal potential, it is vital that children are provided with nutritionally sound diets. Diet and exercise patterns during childhood and adolescence may spell the difference between health and risk of disease in later years.Everyone agrees that adequate nutrient intake is important to all living things. Without food or water, life on earth would cease to exist. In the field of medical health, some gains have been made in meeting maternal and child nutritional needs. There is great community awareness regarding the importance of meeting the nutritional needs of the developing foetus, child and adults. Behavioural problems such as hyperactivity, learning disabilities, mental illness, aggressive and antisocial behaviour, and juvenile delinquency have been purportedly linked to the potential influence of foods or nutrients. Subtle differences in behaviour can occur with physiologic variation in food intake. Components of foods can also be used as drugs. Starvation can impair neuronal maturation and can have lasting effects upon behaviour and intellectual performance. The extent of starvation's impact upon the brain depends upon whether under nutrition occurred during a critical phase in brain development. Short-term fasting has small, but significant, effects upon intellectual performance. Tryptophan, tyrosine, and choline in the diet are used as precursors for neuronal synthesis of serotonin, dopamine and norepinephrine, and acetylcholine, respectively. It is likely that the brain's sensitivity to certain components of the diet exists to permit monitoring of food intake by the central nervous system. Tryptophan, tyrosine, and choline may be useful in treatment of humans with sleep disorders, pain depression, mania, hypertension, shock, or dyskinesia. Food additives may exacerbate hyperactive symptoms in a small proportion of children with attention deficit disorder. This review mainly attempts to describe the intake food should provide the basis for effective food and nutritional surveillance strategies along with promote healthy eating habits.

Rehabilitation Research and Practice , 2012, DOI: 10.1155/2012/593405
Abstract: Counseling training in graduate programs continues to be underrepresented. If parental queries are not addressed adequately, they keep visiting one doctor after another. Objective. The aim of the study is to identify maternal needs of children with hearing impairment at two stages of habilitation, that is, just after diagnosis (group I) and after receiving 1 to 3 years of language therapy (group II). Methods. Two groups of mothers were asked to speak their queries about aural habilitation of their children. Queries were recorded, summarized, and categorized as per their priorities. Results. Group I mothers wanted to know about how the child would learn to listen and speak (45%), causes of hearing loss (33.7%), understanding the ear and hearing (10.2%), understanding the audiogram (7%), and coping with emotional aspects of hearing loss (5%), while group II parents had priorities concerning speech development (24.5%) followed by child independence and employment (17.3%), schooling (15.6%), problem behaviors (11%), amplification device (9.4%), duration of therapy (8%), future of the child (8%), and questions about how can my child get adjusted to the “normal” world (6%). Conclusions. Culture- and language-specific materials to explain these issues need to be developed. 1. Introduction Apt counseling may have a direct impact on the success of early hearing detection and intervention programs along with reducing the negative effects of permanent hearing loss [1–3]. The clinician is confronted with a difficult task during the first few contacts with the parents because they are in a state of shock and they seek help in changing the child’s behavior so that their anxiety can be dissipated [4]. When asked, patients too frequently report that audiologists do not seem to understand their difficulties [5, 6]. This may puzzle audiologists, because, as educated professionals, they feel that they “do deeply” understand their patient’s difficulties. The breakdown may occur because of a mismatch in communication intent; that is, although the audiologist’s responses are not wrong, they do not match the intent of the patient’s remarks [7]. English et al., 1999 suggested that this communication mismatch may be a natural consequence of graduate training, whereby student success is measured in terms of adequately explaining high-level technical information to instructors and supervisors. In India, it is in part is also because of the undue influence of the medical model of treatment in dealing with permanent hearing loss (HI). Audiologists are influenced by the medical
Valproate, thalidomide and ethyl alcohol alter the migration of HTR-8/SVneo cells

Abstract: In the present study, the effects of sodium valproate, thalidomide and alcohol on the migration of human first trimester trophoblast cell line (HTR-8/SVneo) were examined in vitro. Cells were cultured in the wells of 48-well culture plates as mono or multilayers. Circular patches of cells were removed from the center of the wells by suction, and the migration of cells into the wound was studied using microscopy. Effects of low and high concentrations of valproate, thalidomide and alcohol were examined on the healing of wounds and on the migration rate of cells by determining the wound areas at 0, 3, 6, 12, 24 and 48 h. Effects of drugs and alcohol on the proliferation and the expression levels of integrin subunits beta1 and alpha5 in cells were examined.The migration rates of trophoblast differed between wounds created in mono and multilayers of cells. Exposure to teratogens altered the migration of trophoblast into mono and multilayer wounds. The effects of valproate, thalidomide and alcohol on the proliferation of cells during the rapid migratory phase were mild. Drug exposure caused significant changes in the expression levels of beta1 and alpha5 integrin subunits.Results suggest that exposure to valproate, thalidomide or alcohol during the first trimester of pregnancy may change the ultrastructure of the placenta by altering the migration of trophoblast cells and this effect may be mediated by drug- or alcohol-induced changes in the expression levels of beta1 and alpha5 integrin subunits.Epidemiological findings and studies with animal models reveal that impaired growth in utero and size at birth are critical determinants of the onset of various disease processes later in life [1]. Optimum intrauterine growth depends on several factors including proper nourishment of the developing fetus by maternal blood through the placenta [2]. Accordingly, proper development of the placenta plays a significant role in determining the health and well being of the offspring. T
‘But it’s just a spinal’: Combating increasing rates of maternal death related to spinal anaesthesia
Z Farina, C Rout
South African Medical Journal , 2013,
Abstract: The number of women dying as a result of spinal anaesthesia during caesarean section in South Africa is steadily increasing in the triennial reports of the National Committee on Confidential Enquiry into Maternal Deaths (NCCEMD). This article postulates some of the reasons behind this phenomenon. The concern is raised that spinal anaesthesia is being undertaken inappropriately by poorly trained practitioners. A case is made for the rigorous application of known safety standards and for doctors to be appropriately trained in anaesthesia and to be solely responsible for the care of the mother during caesarean section. The need for doctors to be trained and prepared to administer general anaesthesia when required is noted.
The Civil War in Southern Sudan and Its Effect on Youth and Children
Biel, Melha Rout
Social Work and Society , 2003,
Abstract: The Civil War in Sudan, which began in June 1983, has caused a numbers of social, cultural and economical problems for Sudan. Many social changes took place, not only in the southern Sudan, where the war has been fought since its inception, but also in the Sudanese Nation as a whole. In this contribution, I would like to give a short summary about the effect of the war on the Sudanese society, in general, and on youth and children, in particular. This is important, because youth and children are the future of every nation. Because the youth and children in southern Sudan are gravely affected by the current war, this article will specifically address these effects. Youth and children in the North of the country are, however, almost equally affected by the conflict. After discussing historical background of Sudan and its political and developmental condition, I will briefly summarize the social situation and the role of social work in Sudan during and after the conflict.
Non-traumatic intraosseous cerebrospinal fluid cyst with associated craniovertebral anomalies: A case report and suggested mechanism of formation
Thomas Tony,Rout Damodar
Neurology India , 2010,
Abstract: Intraosseous cerebrospinal fluid (CSF) cysts, also known as intra-diploic arachnoid cysts, are usually of post-traumatic origin. Lesions presenting without a history of trauma are rare and are presumed to be of congenital origin. We report a young man with an intraosseous cystic lesion containing CSF and communicating with the intracranial subarachnoid space through a dural opening. The presence of other congenital defects of the skull and spine could be a pointer in this direction. Surgical management involves craniectomy and repair of the dural defect followed by cranioplasty for the bony defect.
