Modeling the Spatial Distribution of Black-Necked Cranes in Ladakh Using Maximum Entropy
Meenakshi Chauhan,Randeep Singh,Puneet Pandey National Institute of Ecology 2023 국립생태원회보(PNIE) Vol.4 No.2
The Tibetan Plateau is home to the only alpine crane species, the black-necked crane (Grus nigricollis). Conservation efforts are severely hampered by a lack of knowledge on the spatial distribution and breeding habitats of this species. The ecological niche modeling framework used to predict the spatial distribution of this species, based on the maximum entropy and occurrence record data, allowed us to generate a species-specific spatial distribution map in Ladakh, Trans-Himalaya, India. The model was created by assimilating species occurrence data from 486 geographical sites with 24 topographic and bioclimatic variables. Fourteen variables helped forecast the distribution of black-necked cranes by 96.2%. The area under the curve score for the model training data was high (0.98), indicating the accuracy and predictive performance of the model. Of the total study area, the areas with high and moderate habitat suitability for black-necked cranes were anticipated to be 8,156 km<sup>2</sup> and 6,759 km<sup>2</sup>, respectively. The area with high habitat suitability within the protected areas was 5,335 km<sup>2</sup>. The spatial distribution predicted using our model showed that the majority of speculated conservation areas bordered the existing protected areas of the Changthang Wildlife Sanctuary. Hence, we believe, that by increasing the current study area, we can account for these gaps in conservation areas, more effectively.

Background: Dental anxiety is a matter of serious concern to pediatric dentists as it may impede the efficient delivery of dental care. If not adequately resolved, a persistent negative response pattern may emerge. Thaumaturgy, commonly known as magic trick, has become popular recently. It is a tool that distracts and relaxes the child by using magic trick while the dentist performs necessary treatment. Hence, the aim of this study was to evaluate the effectiveness of Thaumaturgic aid in alleviation of anxiety in 4-6 - year-old children during administration of local anesthesia using the inferior alveolar nerve block (IANB) technique. Methods: Thirty children aged between 4-6 years with dental anxiety requiring IANB were included in this study. Patients were divided equally into two groups: Group I, thaumaturgic aid group and Group II, conventional non-pharmacological group using randomization. Anxiety was measured before and after using the intervention with Raghavendra Madhuri Sujata-Pictorial scale (RMS-PS), Venham's anxiety rating scale, and pulse rate. All the data were tabulated and compared using statistical analysis. Results: Children in thaumaturgy group (Group- I) exhibited significantly lower anxiety during IANB in comparison with children in the conventional group (Group- II) and the difference was statistically significant. Conclusion: Magic tricks are effective in reducing anxiety among young children during IANB; Moreover, it expands the arsenal of behavior guidance techniques for treatment of children with anxiety and plays an important role in shaping the behavior of a child in pediatric dentistry.

Brassica oleracea Extracts Prevent Hyperglycemia in Type 2 Diabetes Mellitus
Sumeet Gupta,Satish Burman,Anroop B. Nair,Samrat Chauhan,Debabrata Sircar,Partha Roy,Meenakshi Dhanwat,Debrupa Lahiri,Dinesh Mehta,Rina Das,Hany Ezzat Khalil 한국식품영양과학회 2022 Preventive Nutrition and Food Science Vol.27 No.1
This study investigated the protective effect of extracts from flowers of Brassica oleracea L. var. italica Plenck on type 2 diabetes mellitus and its associated disorders. Three different doses of each extract (petroleum ether, ethanol, and aqueous) were administered orally for 42 days. Biochemical parameters, behavioral studies, and histological studies were measured at different periods. Mortality was found to be nil up to 2,000 mg/kg. Statistically significant (P<0.001) improvement in serum glucose level was observed in the groups receiving 400 mg/kg of petroleum ether, aqueous, or ethanol extracts compared with the negative control group. Insulin level was decreased by aqueous extracts, whereas lipid profiles were improved by aqueous and ethanol extracts. A reduction in transfer latency was observed in treatments of all three extract types. Ethanol extract treatment (400 mg/kg) showed maximum percentage inhibition in a lipid peroxidation assay. Additionally, the aqueous and ethanol extract treatments markedly reduced tumor necrosis factor-α, interleukin-6, and glycosylated hemoglobin levels. Histological results showed that high doses of extracts alleviated the damages induced by type 2 diabetes mellitus in various organs and bones. Based on the results of this study, it can be concluded that B. oleracea has the potential to alleviate type 2 diabetes mellitus.
