In the present investigation, the effect of ½ strength liquid Murashige and Skoog (MS) medium supplemented with 1 mg/l Indole-3-butyric acid (IBA) and different sucrose concentrations (1.5%, 3%, 6%, 9%, or 12%) was studied on microrhizomes induction of C. caesia. The shoot length, root length and microrhizomes dry weight of C. caesia decreased significantly at 6% sucrose and above. When compared to the control (1.5% sucrose), the current water content significantly decreased at 6% sucrose. The optimum concentration for in vitro microrhizomes induction in C. caesia was 6% sucrose. Therefore for further experiments, the 6% sucrose was used. We also studied the effect of silver nanoparticles (AgNP) on microrhizome induction and antioxidant activity in C. caesia cultures. Field-grown C. caesia rhizomes extract was used in the green synthesis of AgNP. The synthesized AgNP was further characterized through scanning electron microscopy and X-ray diffraction. The AgNP, ranging from 0, 0.025, 0.05, 0.075 or 0.1 mg/l was supplemented in ½ strength liquid MS medium with 6% sucrose and 1 mg/l IBA. The MS medium with 0.05 mg/l AgNP found with significant morphological changes in C. caesia cultures (root number, root length and microrhizomes fresh weight). For the total phenolic and total terpenoids content estimation as well as for antioxidant activity analysis, the extracts of un-treated cultures (6% sucrose + 1 mg/l IBA, without AgNP), AgNP treated cultures (6% sucrose + 1 mg/l IBA with 0.025 and 0.05 mg/l AgNP) was used. The 0.025 and 0.05 mg/l AgNP enhanced the phenolic and terpenoid content in the cultures compared to the field-grown mother plant. The antioxidant activity of the cultures treated with AgNP also increased compared to un-treated cultures and field-grown mother plant. The Gas Chromatography-Mass Spectrometry (GC-MS) analysis revealed that the extract treated with 0.05 mg/l AgNP had increased production of monoterpene (camphor) and sesquiterpenes (β-elemenone and curcumenone). These increased terpenes could be responsible for the enhanced antioxidant activity of C. caesia cultures. \u0000","PeriodicalId":17214,"journal":{"name":"Journal of Ravishankar University (PART-B)","volume":"226 21","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141012661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the present study, we examined the 24-hour rhythm in the pit-building behavior of 16 antlion larvae collected from the PRSU campus, Raipur. We kept each larva individually in a plastic drinking cup in the laboratory. We observed the pit-building behavior of antlion larvae by monitoring two variables, i.e., the time lag for the initiation of pit reconstruction (TLIPR) and total time for pit construction (TTPC) after its demolition over three consecutive days, at four time points each day. We employed single Cosinor Rhythmometry to compute the characteristics of 24-hour rhythm in TLIPR and TTPC. We found a statistically significant 24-hour rhythm in both variables. We found the peaks of TLIPR between 14.32 h and 17.15 h, irrespective of days. Further, the factor 'time of the day' produced a statistically significant effect on the TLIPR and the maximum and minimum values were found at 14.00 h and 02.00 h, respectively. This implies that antlion larvae took time during the afternoon to initiate pit construction. This phenomenon was reversed during nighttime. TTPC exhibited a statistically significant 24-hour rhythm on day 3 and at the group level. We concluded that antlion larvae exhibit a 24-hour rhythm in pit-building behavior and are nocturnal as they initiate pit construction quickly at night. \u0000","PeriodicalId":17214,"journal":{"name":"Journal of Ravishankar University (PART-B)","volume":"299 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141012569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ophthalmic mycoses, often known as ocular fungal infections, are a significant cause of morbidity and blindness. For fungus infections, a brand-new azole derivative has been authorized. New immunological techniques would also be beneficial in the future for enhancing patient outcomes. Treatment of ocular illnesses presents a significant barrier in terms of getting medications into the eyes using traditional drug delivery methods, such as solutions. The main barriers are those between blood and the eyes, between lachrymal fluid and the eyes, and between medication losses from the ocular surface brought on by lachrymal fluid secretion. To increase the bioavailability and lengthen the residence duration of medications administered topically to the eye, a variety of ocular drug delivery carriers have been developed. The microemulsion is created using the PHASE TITRATION METHOD. Due to the dual hydrophilic and lipophilic properties of microemulsions, the loaded medications can diffuse passively and become significantly partitioned in the varying lipophilic-hydrophilic ocular barrier. This abstract will provide details on the microemulsions used to treat fungal infections of the eyes. \u0000","PeriodicalId":17214,"journal":{"name":"Journal of Ravishankar University (PART-B)","volume":"28 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141011337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Treatment of burn injuries has always been the responsibility of burn specialists. Both local and systemic therapy have long been advised for treating burn injuries and minimizing burn scars. This review summarizes the treatment of burn injuries brought on by a variety of physical and chemical agents requires unique regimens that are completely different from those used to treat any other traumatic injuries. Other acute injuries that undergo entire blood loss result in shock, but major burns that experience significant plasma loss due to increased capillary permeability result in distress. Burn injuries are initially sterile compared to the majority of other injuries, however, due to the immunocompromised state of burn patients and injury infection frequently ends in death in serious burns.

Speech recognition intelligence is employed in various applications such as digital assistance, security, and other human-machine interactive products. In the present work, three open-source acoustic datasets, namely SAVEE, RAVDESS, and EmoDB, have been utilized (Haq et al., 2008, Livingstone et al., 2005, Burkhardt et al., 2005). From these datasets, six emotions namely anger, disgust, fear, happy, neutral, and sad, are selected for automatic speech emotion recognition. Various types of algorithms are already reported for extracting emotional content from acoustic signals. This work proposes a time-frequency (t-f) image-based multiclass speech emotion classification model for the six emotions mentioned above. The proposed model extracts 472 grayscale image features from the t-f images of speech signals. The t-f image is a visual representation of the time component and frequency component at that time in the two-dimensional space, and differing colors show its amplitude. An artificial neural network-based multiclass machine learning approach is used to classify selected emotions. The experimental results show that the above-mentioned emotions' average classification accuracy (CA) of 88.6%, 85.5%, and 93.56% is achieved using SAVEE, RAVDESS, and EmoDB datasets, respectively. Also, an average CA of 83.44% has been achieved for the combination of all three datasets. The maximum reported average classification accuracy (CA) using spectrogram for SAVEE, RAVDESS, and EmoDB dataset is 87.8%, 79.5 %, and 83.4%, respectively (Wani et al., 2020, Mustaqeem and Kwon, 2019, Badshah et al., 2017). The proposed t-f image-based classification model shows improvement in average CA by 0.91%, 7.54%, and 12.18 % for SAVEE, RAVDESS, and EmoDB datasets, respectively.

Conventional pest control methods, such as chemical pesticides, have limitations and adverse environmental effects. Therefore, there is a growing need for sustainable and eco-friendly alternatives in pest management. This review explores the potential of entomopathogenic fungi as a promising biological control agent for insect pests in agriculture. The review begins by providing an overview of entomopathogenic fungi and their significancce. These fungi possess unique mechanisms to infect and kill insect pests. The mode of action involves attachment of fungal spores to the insect's cuticle, followed by penetration, colonization, and release of toxic metabolites within the host. Various factors influence the efficacy of entomopathogenic fungi, including environmental conditions, insect host susceptibility, and formulation/application methods. The benefits of entomopathogenic fungi as biological control agents are discussed, including their compatibility with integrated pest management (IPM) strategies and minimal impact on non-target organisms. However, challenges exist in scaling up their commercial application. The review presents case studies showcasing successful field applications of entomopathogenic fungi in pest management. Future prospects and research directions are identified, emphasizing the importance of continued advancements in understanding the interactions between entomopathogenic fungi and insect pests. Regulatory frameworks and public acceptance are crucial for the widespread adoption of these fungi in agriculture. In conclusion, entomopathogenic fungi offer immense potential as sustainable and effective tools for biological control of insect pests in agriculture. Their ability to target specific pests, compatibility with IPM, and minimal environmental impact make them a viable alternative to chemical pesticides. Further research, collaboration, and implementation are necessary to fully harness the potential of entomopathogenic fungi in integrated pest management strategies.","PeriodicalId":17214,"journal":{"name":"Journal of Ravishankar University (PART-B)","volume":" 22","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139135601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
