Evaluation of the antipeptic ulcer activity of the seed extract of sesame (Sesamum indicum) in stress induced peptic ulcers in rats
Background: The peptic ulcers can be developed inside the inner lining of the stomach (gastric ulcer) or the small intestine (duodenal ulcer). Around 10% population of the world is suffering from the peptic ulcer disease. From the ancient times there is a reference about herbal extracts like Sesame indicum for the treatment of various diseases. The aim of the study is Evaluation of the anti-peptic ulcer activity of the seed extract of sesame (Sesamum indicum) in stress induced peptic ulcers in rats.Methods: The study was carried out by stress-induced ulcer model in wistar rats. The antiulcer activity of S. indicum (0.5, 1mg/kg p.o. for 7 days) was compared with standard drugs (pantoprazole). The studied parameters were mucin content, gastric volume, pH, total acidity, free acidity, ulcer index, size and number.Results: The low and high dose of S. indicum extract significantly reduced gastric mucosal lesion, mucin content, volume of gastric juice, gastric pH, free and total acidity when compared to positive control group. The high dose of S. indicum extract showed comparable results in parameters like effect on mucin content, gastric volume, pH, free acidity and total acidity with standard group. The statistical significant changes noted only in ulcer size, number and index.Conclusions: Although the high dose S. indicum (1mg/kg) group showed significant gastric protection against ulcer induced by cold restraint method. However, no clear inference can be drawn at this stage and hence there is a need for further extensive research
Understanding Collaborations in Virtual World
Virtual worlds (VW) have paved a new and important channel for workplace collaborations. However, analysts have noted that several organizations that made a strong entrance into using VW as a nouveau channel for communication and collaboration are stepping back due to limited user response. Motivated by this fact, we propose a trust-theoretic ‘virtual world collaboration model’ for collaborations in virtual worlds. The model, grounded in literature on ‘technology adoption’ and ‘trust’, theoretically examines the role of trust in motivating users for using this rich virtual communication medium for collaborations. Results establish the important roles of perceived social presence and perceived structural assurance for fostering user trust in VW. Further, results also indicate that user trust is significantly related to both extrinsic and intrinsic motivations, which in turn influence the behavioural intention to use the VW. Implications for research and practice are discussed
Design of Low-Cost Hydroponic Technology for Cultivation of Leafy Vegetables for Human Food Security in a Cold Desert Area of the Trans-Himalayan Range
For many decades, food security has been a worldwide concern. The present research aimed to examine an efficient technique for planting system i.e. hydroponic (a soil less system of farming) and statistical experimental design approach was used to compare the growth of different Leafy Vegetables (Spinach and Lettuce Varieties) in the Cold Desert Region of Trans Himalaya under the designed hydroponic system. The results showed that the leafy vegetable variety that were grown in the NFT system, exhibited significant differences in above attributes. The BC ratio of nutrient solution was found to be four times higher
Malaysian nasal polyps: eosinophil or neutrophil-predominant
Eosinophil-type nasal polyp (NP) is common in Western population. This aim of this study was to determine the histology type of NP among different Malaysian ethnic groups. A total of 122 chronic rhinosinusitis with nasal polyposis (CRSwNP) patients were retrospectively enrolled and demographic data was recorded. The histological slides were retrieved. The number of eosinophils and non-eosinophils were counted and average number of inflammatory cells for each high power field was calculated. Eosinophil-predominant was seen in 32.8% of patients and 67.2% was non-eosinophil-predominant. Phenotypes of NP significantly showed an association with ethnicity (x² = 8.322; p < 0.05). A total of 78.9% of Chinese nasal polyps showed non-eosinophil predominant, while Malay and Indian nasal polyps revealed 71.9% and 40.7% of non-eosinophilic phenotype, respectively. Our study showed that Malaysian population had a non-eosinophilic phenotype of nasal polyps. There was a significant association in Malaysian ethnicity with the highest percentage in Chinese population
Unified Angular Momentum of Dyons
Unified quaternionic angular momentum for the fields of dyons and
gravito-dyons has been developed and the commutation relations for dynamical
variables are obtained in compact and consistent manner. Demonstrating the
quaternion forms of unified fields of dyons (electromagnetic fields) and
gravito-dyons (gravito-Heavisidian fields of linear gravity), corresponding
quantum equations are reformulated in compact, simpler and manifestly covariant
way
Quaternion Analysis for Generalized Electromagnetic Fields of Dyons in Isotropic Medium
Quaternion analysis of time dependent Maxwell's equations in presence of
electric and magnetic charges has been developed and the solutions for the
classical problem of moving charges (electric and magnetic) are obtained in
unique, simple and consistent manner
Quaternion Gravi-Electromagnetism
Defining the generalized charge, potential, current and generalized fields as
complex quantities where real and imaginary parts represent gravitation and
electromagnetism respectively, corresponding field equation, equation of motion
and other quantum equations are derived in manifestly covariant manner. It has
been shown that the field equations are invariant under Lorentz as well as
duality transformations. It has been shown that the quaternionic formulation
presented here remains invariant under quaternion transformations.Comment: Key Words: Quaternion, dyons, gravito-dyons, gravi-electromagnetism.

Genetic diversity analysis of Myristica and related genera using RAPD and ISSR markers
Genetic diversity among seven species of Myristica, two of its related genera and an unidentified species was analyzed using 46 PCR markers (30 RAPD and 16 ISSR). This is the first study on molecular genetic diversity of the rare, endangered and endemic Myristica species and its related genera. RAPD and ISSR analyses yielded 497 and 262 bands with 98.1% and 97.3% polymorphism, respectively. By combining markers, a total of 759 bands were detected of which 743 (97.8%) were polymorphic with an average of 16.1 bands per primer. High level of existing genetic variability was evident from the high percentage of polymorphism. Combined analysis of RAPD and ISSR markers resulted in better distinction of species. The mean polymorphic information content (PIC) indicated that both the marker systems are effective in detecting polymorphism either individually or in combination. Similarity coefficient (Jaccards) varied from 0.22 to 0.62 when markers were combined and the pattern was similar to RAPD with a high Mantel matrix correlation (r=0.95). Principal Coordinates Analysis (PCA) conformed to cluster analyses. First three most informative PC components explained 51.1%, 49.3% and 46.5% of total variation. A maximum similarity of (63%) was observed between Gymnocranthera canarica and the unidentified species of Myristica. Knema andamanica and Myristica prainii were found to be the most distinct (17.7%). Similarities at molecular level were close to either the morphological traits (mace and fruit/seed characters) or the geographical location. Species specific bands could be identified from all the accessions under study, which has the potential for development into SCAR (Sequence Characterised Amplified Region) markers for genotype fingerprinting or development of specific DNA probes for identification and authentication.
 
Recent advancements in Edible Oyster (Crassostrea madrasensis) hatchery technology in India
Oyster farming remains a vital industry, catering to the
culinary preferences of millions while also championing
responsible aquaculture practices and environmental
conservation. As we forge ahead in our quest for
sustainable seafood production, oyster farming serves
as a remarkable example of how human innovation
can coexist harmoniously with nature, ensuring a legacy for these exquisite molluscs for generations to
come. Currently, the time required for freshly produced
spat to mature into marketable-sized oysters stands
at three to four years in the subtropical countries that
dominate the industry. India, with its tropical climate,
faster growth rates, abundant suitable areas for oyster
farming, and cost-effective labour, has a promising
opportunity to enter the oyster export market
