Rapid estimate of adult literacy in medicine and dentistry-20 and oral health status among adolescents, India: A cross-sectional study
No full textINTRODUCTION: Health literacy is an important issue in public health. Individuals with low health literacy skills often have poorer health knowledge and health status than those with higher literacy level. Research documented on the assessment of oral health literacy in health settings and its association with oral health outcomes for adolescents was scarce.
AIMS AND OBJECTIVES: The aim of this study is to assess oral health literacy about oral health status among adolescents attending pre-university colleges in Mysore , India.
MATERIALS AND METHODS: A cross-sectional study was conducted over a period of 2 months among 401 adolescents attending pre-university colleges. Rapid Estimate of Adult Literacy in Medicine and Dentistry-20 (REALMD-20) and the WHO oral health assessment pro forma for adults (2013) were used. Data were analyzed using SPSS version 22 and tests employed were Chi-square test, ANOVA, and multiple linear regression.
RESULTS: Mean REALMD-20 score was 10.31 ± 5.7. The study participants belonging to science course (12.69 ± 5.0) and private pre-university colleges (11.76 ± 5.8) had significantly higher REALMD-20 scores. Mean decayed, missing, and filled teeth among the study participants was (0.42 ± 0.9). Type of college, course, dental history, and number of dental visits was significantly associated with oral health literacy while oral health parameters were not significantly associated.
CONCLUSION: Oral health literacy was not significantly associated with oral health status. However, long-term studies are recommended to validate the results of the present study
Changes in protein profile and RNA content of Apis mellifera worker pupa on parasitization with Tropilaelaps clareae
No full textTropilaelaps infestation of Apis mellifera pupa caused reduction in total protein concentration of the infested pupa. This may be due to protein feeding by mite. The additional protein fractions observed by SDS-PAGE and the difference in the nature of free amino acids suggested synthesis of newer proteins perhaps related to the stress response of the host. This opinion is strengthened by the increase in concentration of RNA ( 184.580±36.987 in non-infested pupa and 293.402±50.329 in infested pups) observed in the present study which was responsible for increased transcription of genes encoding antiparasite peptides as reported by other workers
A new species from Genus Megachile Subgenus Callomegachile (Hymenoptera, Megachilidae) from Chandigarh and Punjab plains
No full textA new species Megachile pseudodisjuncta of the bee is being reported from Genus Megachile and Subgenus Callomegachile. It bears a close resemblance to M. disjuncta from which it has been distinguished on the basis of certain morphological characters and genitalia. Megachilid bees bear utmost significance because they are very good pollinators of both cultivated and wild fauna. Consequently, their taxonomic identification and conservation are very crucial. The detailed taxonomically important morphological characters of both the species were studied and photographed. Male sternum and genitalia were studied microscopically and photographed. The material examined and floral associations have also been presented in the paper

Knowledge of the life history and nesting habits of Megachile bees will pave the way for their manipulation so that these can be used to increase pollination. Documentation of the genera and species will increase our knowledge of the biodiversity of these bees in the study area
A study on biochemical composition of the sting gland (poison gland) and the reservoir (poison sac) of the dwarf honey bee Apis florea F. workers
No full textThe glands associated with the sting apparatus of worker honey bee Apis florea produce Venom which is known to be composed of a wide spectrum of biomolecules ranging from biogenic amines to peptides and proteins. The Venom apparatus showed the presence of two important associated exocrine glands i.e. Venom gland and Dufors gland. The secretions of both glands are apocrine and are released into the lumen to be stored in the venom sac. The presence of some exocrine cells in the distal part of venom sac which is otherwise known to only store the component of Venom gland led to the present study. The present study that there were considerable differences in the biochemical composition of Venom gland and Venom sac secretions of Apis species The concentration of lipids (Sting gland =1.423±0.0001 and Reservoir = 1.21±0.0067), proteins (Sting gland=0.440±0.0226, Reservoir = 0.390± 0.032), activity of acid phosphatase (Sting gland=112.09±21.100, Reservoir=22.63±1.467) and hexokinase (Sting gland=20.7±4.016, Reservoir=10.66±2.465) was found to be more in case of Venom gland while cholesterol(Sting gland=0.138±0.0161 reservoir=0.324±0.00323), glucose (Sting gland=189±1.31, Reservoir=321±7.19), free amino acids, and activity of alkaline phosphatase (Sting gland=21.03±0.195 Reservoir=22.4±0.685) was more in Venom sac. Glycogen was absent in both Venom gland and Venom sac of Apis species as confirmed by the absence of glucose-6-phosphatase activity. It is established from the present study that Venom sac also secretes various biochemicals and enzymes which are added to the total Venom
Characterization of cavity dwelling honey bees using enzyme polymorphism
No full textThe most intensively studied of all insects are perhaps honey bees. Recognition of valid honey bee species has been difficult for several reasons. Most important reason has been the movement of honey bees all over the world for bee keeping which has resulted in their hybridization. Another problem is that scientists and bee keepers do not always use the same criteria for identification. While scientists are concerned with the biological parameters, bee keepers are more interested in behavioral traits. Even within a single species there are locally adapted populations called geographic ecotypes, which differ from each other in several morphological, biological, molecular and economic characteristics. Beside behavioral, morphological and cytogenetic evidence, electrophoretic data provide strong support for phylogenetic relationships among insects. Apis cerana and Apis mellifera are the Eastern and the Western cavity dwelling honey bees. Their habit of nesting in dark, enclosed spaces made it possible for man to domesticate them and to use them as a highly commercial industrial enterprise. A. mellifera is thought to have originated in the African tropics or Asia and colder European climates. The recent movement of bees by European settlers for bee keeping has resulted not only in worldwide distribution of Apis mellifera but has also led to some degree of hybridization between subspecies. On the other hand there has also occurred isolation of populations either by distance or by barrier giving rises to newer subspecies or races. To differentiate these honey bees on the basis of biochemical polymorphism alcohol dehydrogenase provided significant results and was observed to be an additional marker for the species
Identification of Suitable Spectral Bands Related to Soil Properties of Major Soils of Telangana, India
No full textA study was conducted to identify suitable spectral bands related to soil properties of major soils of Telangana using hyperspectral data. A total of 200 surface soil samples were collected from district of Sangareddy (20 soil samples), Yadadri Bhuvangiri (20 soil samples), Nizamabad (20 soil samples), Adilabad (20 soil samples), Jayashankar Bhupalpally (60 soil samples), Nagar Kurnool (20 soil samples) and Nalgonda (40 soil samples) analyzed for soil properties viz., pH, electric conductivity (EC), organic carbon, total nitrogen, total phosphorus, total potassium, soil texture (percent clay). Soil spectral data (350-2500 nm) was measured using ASD spectroradiometer and correlated with soil properties using Pearson correlation test. Result shows that the soil properties like pH, OC, total N, total K , total Mn, % Clay showed significant negative correlation at 1210-1280 nm (r= -0.345**) for Ph, 610-630 nm (r= -0.415**) for OC, 390-410 nm (r= -0.180*, 0.183*, 0.175*, 0.170*) for total N, 360-390 nm (r= -0.174**,-0.158**,-0.163**,0.160**) for total K , 590-610 nm (r= -0.527** and -0.526**) for clay %.However significant positive correlation was observed with ECand 1110-1130 nm (r= 0.150* and 0.149*). These sensitive bands for soil parameters can be further used for prediction of soil properties
