Analysis of Drought Susceptibility Index in Indian Mustard [Brassica juncea (L.) Czern and Coss]
(Agricultural Research Communication Centre, 2021) Akanksha; K. Srivastava; Ayushi Srivastava; B. Sinha
Background: Climatic variations such as drought have high level of impingement on the yield of rain-fed crops like mustard. A drought is an extended period of months or years when region notes a deficiency in its water availability. Water stress causes heavy yield losses in Indian mustard (17-94%). Low water availability during stem elongation, flowering and pod development causes reduction of pods per plant leading to reduction in grain yield. Very meagre efforts have been made towards improving drought tolerance of this crop. Hence there is an urgent need for, development of water use efficient genotypes. Drought Susceptibility Index (DSI) is a measure of drought, based on loss of yield under drought conditions in comparison to the yield under normal conditions. It expresses the separate effects of yield potential and drought susceptibility on yields under drought. In these terms, lower DSI is considered synonymous with higher drought tolerance. In view of above facts, present study is aimed at investigating the effects of drought on yield attributing traits with, the objective of identifying Indian mustard genotypes and their hybrids which can withstand water stress with minimum loss in yield. Methods: Nine Indian mustard genotypes and their F1s were evaluated under irrigated and rainfed conditions to study the effect of drought by calculating DSI, on yield and yield traits and to characterize their relative tolerance against drought at the Agriculture Research Farm, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during Rabi 2017-18 season. Observations were made for different yield and yield related traits. Result: Genotype RB-50 was found as tolerant for seed yield per plant with DSI 0.38 while hybrids RB-50*RH-749 and RB-50xGiriraj were exhibiting tolerant DSI values for siliqua per plant, 1000 seed weight, seed yield per plant and oil content. These parents and F1s would serve as useful donors and hybrids respectively, in mustard breeding programmes for improving drought tolerance. © 2021. All Rights Reserved.
Chronic Lower Limb Edema
(Springer Nature, 2022) Ram Niwas Meena; Vipul Srivastava; Akanksha; B.R. Akshay
Chronic edema is a word that refers to edema that has been present for longer than 3 months duration. It is a catch-all word that encompasses not only traditional “lymphedema” but also chronic swelling with a more complicated origin. With persistent consequences of edema such as cellulitis and the impact on quality of life, it imposes a large burden of hidden illness and unacknowledged morbidity. The goal of chronic edema treatment is to minimize swelling and prevent its recurrence. Chronic edema management is dependent on three things. First is the early detection and treatment which are critical for avoiding problems. Second is a multidisciplinary approach to all of the physical, psychological, and social consequences that come with it. Third, collaboration among healthcare experts which is critical so that the best therapy is administered in the best healthcare setting, thereby enhancing patient quality of life and allowing them to participate actively in their own care. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2022.
Combining ability studies for yield and quality parameters in basmati rice (Oryza sativa L.) genotypes using diallel approach
(Indian Society of Plant Breeders, 2019) Akanksha; H.K. Jaiswal
General and specific combining ability of six basmati rice varieties and their fifteen hybrids made through diallel mating without reciprocals for different yield and quality parameters were studied to select the general combiners for future domestic breeding programs. The Analysis of Variance showed that the mean squares due to general and specific combining ability were highly significant for all the traits indicating that both additive and non-additive gene actions were involved in the inheritance of fourteen yield and quality traits. Significant SCA effects for different characters indicated preponderance of non-additive gene actions in the inheritance of the characters under study. Different lines and hybrids were found as best general and specific combiners for different yield and quality traits, respectively. Thus, important specific cross-combiners can be used effectively in crop improvement programs to develop varieties, and further validation of specific genes to develop gene-based perfect markers in rice breeding. © 2018 Electronic Journal of Plant Breeding.
Components of genetic variation and graphicalanalysis (VR-WR) for some yield and quality characters in Basmati rice (Oryza sativa L.)
(Plant Archives, 2019) Akanksha; H.K. Jaiswal
Gene action for eight yield and six quality traits were evaluated through Hayman’s analysis (graphical and component) for fifteen direct F1 hybrids along with their six parents of Basmati rice were studied in a randomized complete block design with three replications. Significant differences were observed among parents, hybrids and hybrids versus parents for most of the agronomic, yield and quality characters of hybrids. Valid graphical analysis were explained for characters like plant height, 100 grain weight, days to 50% flowering, days to maturity, kernel length before and after cooking and alkali spread value, showing significant deviation of regression coefficient, ‘b’ from zero and non significant deviation of ‘b’ from unity and all these traits revealed over dominance type of intra allelic interaction. Furthermore, component analysis were done for all the traits by examining estimates D, F, H1, H2, h2 and E and proportion of components i.e. (H1/D)0.5 , H2/4H1, KD/KR, h2/ H2 and h2n. The component D, reflecting additive genetic variance was significant for all the characters studied except for effective tillers per plant, seeds per panicle, grain yield per plant, kernel breadth after cooking and amylose content. The ratio (H1/D)0.5 which measured the mean degrees of dominance over all loci was more than one indicating over dominance for all the characters. The ratio, H2/4H1, close to 0.25 for characters effective tillers per plant, panicle length, grain yield per plant, kernel breadth, amylose content indicating nearly symmetrical distribution of positive and negative alleles at loci showing dominance for the traits. Likewise, ratios, KD/KR and h2/H2 revealed presence of dominant genes/group of genes for different traits. Heritability in narrow sense (h2n), more than 50% for Plant Height, Seed per panicle, Kernel length and Kernel Length After cooking indicated major part of additive gene action in phenotypic variability and selection should be effective for improvement of these characters in rice. © 2019 Plant Archives.

Expression of heterosis for yield and its components in indian mustard (brassica juncea l. czern & coss) under timely sown irrigated conditions
(Plant Archives, 2020) Akanksha; Kartikeya Srivastava; B. Sinha
Nine Indian mustard genotypes including standard check, RB-50 and their hybrids were sown under timely sown irrigated condition to study the extent of relative, heterobeltiosis and standard heterosis for seed yield and its components. The analysis of variance revealed that considerable genetic variation existed among the parents and hybrids for most of the traits under study. RB-50×Kranti showed positive and significant value for all the three types of heterosis for 1000 seed weight. RH-119×Giriraj, RGN-298×RH-749, RGN-298×Giriraj, Vardan×RH-749 and Vardan×Giriraj showed standard heterosis for seed yield per plant as well as number of primary and secondary branches. The cross combinations Vardan×Giriraj, RGN-298×RH- 749, RGN-298×Giriraj, Vardan×RH-749 and Vardan×RGN-73 were identified on the basis of standard heterosis alogwith per se performance for seed yield per plant which, could be exploited for getting transgressive segregants in the subsequent generation for developing high yielding varieties. © 2020 Plant Archives.

(Wolters Kluwer Medknow Publications, 2022) Akanksha; Shashi Prakash Mishra; Amrita Ghosh Kar; J.S. Karthik; Aviral Srivastava; Rahul Khanna; Ram Niwas Meena
Background: The use of poly(adenosine diphosphate-ribose) polymerase (PARP) inhibitors for breast cancer (BC) therapy is the subject of debate, and there is an urgent need to understand much the expression and prognostic role of the PARP1 protein. In this study, we have compared the expression of PARP between BC and benign breast disease (BBD) patients and also analyzed the association of PARP expression with clinicopathological parameters in BC. Methods: The study consists of 30 patients with newly diagnosed operable BC who were planned for surgery without neoadjuvant chemotherapy and 15 patients of BBD as a control between 2019 and 2021. Immunohistochemical analyses were performed prospectively on tissue samples. Anti-human PARP1 rabbit polyclonal antibody gives strong nuclear positivity. Internal control was the adipose tissue and the BBD acted as the external control. PARP1 expression was evaluated using the multiplicative quickscore method. Results: The mean age for BC patients was 51.30 ± 10.694 years (range: 25-75 years) while BBD was below 30 years. Overexpression of PARP was present in 25 (83.3%) and weak expression in 5 (16.7%) of BC patients compared to BBD, only 2 (13.3%) patients demonstrated an overexpression of PARP, and 13 (86.6%) patients showed weak expression which showed significant association (P < 0.001). In BC, nuclear PARP (nPARP) overexpression was seen in 22 (73.3%) patients and weak expression of nPARP in 8 (26.7%), whereas 5 (16.7%) patients showed cytoplasmic overexpression. On comparing expression of PARP with clinicopathological parameters, PARP overexpression was significantly associated with older population (age >50 years) (P = 0.002), postmenopausal women (P = 0.029), higher TNM stage (Stage II and III) (P = 0.014), higher histological grade (grade 2) (P = 0.043), and presence of lymphovascular invasion (P = 0.015). Enhanced PARP1 expression is closely correlated with positive estrogen receptor status (P = 0.001) and PR status (P = 0.001). Overall PARP and nPARP overexpression was significantly associated with ER- (P = 0.006 and P = 0.008) and PR-positive (P = 0.006 and P = 0.008) patients. The PARP and nPARP overexpression was significantly associated with nontriple-negative BC patients (P = 0.001 and P = 0.001). Conclusion: We have not come across any study in the literature to compare PARP expression in BC and BBD patients. On the basis of our observations, we concluded that PARP overexpression is a poor prognostic marker in BC. © 2022 Wolters Kluwer Medknow Publications. All rights reserved.
The Health Benefits of Ghee: A Comparative Analysis of Ayurvedic and Modern Scientific Perspectives: A Review
(Agricultural Research Communication Centre, 2025) Vishal Kumar; Akanksha; Saurabh Singh; Ashok Kumar Yadav; Sudhir Kumar; Aman Rathaur
The scientific perspective on dairy fats, including ghee, is evolving. In the past, dairy fats were thought to have adverse health effects, but recent research is revealing their functional benefits and the positive aspects of their fatty acids. This shift in scientific understanding has sparked interest in ghee, a clarified butter derived from milk, which holds cultural significance in India and plays a prominent role in Ayurvedic medicine. While modern scientific studies on ghee’s benefits are limited, Ayurvedic literature extensively documents its therapeutic potential, categorizing different types of ghee based on factors like milk source, manufacturing methodand maturation. To explore ghee’s therapeutic potential further, researchers conducted a review comparing Ayurvedic literature to modern scientific studies. These mentions were grouped into various health benefit clusters. While recent research emphasized cardiovascular health and skin benefits, Ayurveda, an ancient medical system, has emphasized cognitive benefits, gastrointestinal healthand overall nourishment. These aspects are gaining significance as the world’s population ages and chronic diseases become more common. As scientists work to address these health issues, they can look to the detailed descriptions in Ayurvedic texts. These texts provide information about the animal sources of ghee, how it is processedand how it is aged, as well as its associated health benefits. This knowledge could offer valuable insights for guiding future research efforts. Exploring ghee’s traditional usage and formulations could lead to new scientific discoveries and potentially innovative approaches to addressing modern health challenges. © 2025 Agricultural Research Communication Centre.

UAVs as remote sensing platform in glaciology: Present applications and future prospects
(Elsevier Inc., 2016) Anshuman Bhardwaj; Lydia Sam; Akanksha; F. Javier Martín-Torres; Rajesh Kumar
Satellite remote sensing is an effective way to monitor vast extents of global glaciers and snowfields. However, satellite remote sensing is limited by spatial and temporal resolutions and the high costs involved in data acquisition. Unmanned aerial vehicle (UAV)-based glaciological studies are gaining pace in recent years due to their advantages over conventional remote sensing platforms. UAVs are easy to deploy, with the option of alternating the sensors working in visible, infrared, and microwave wavelengths. The high spatial resolution remote sensing data obtained from these UAV-borne sensors are a significant improvement over the data obtained by traditional remote sensing. The cost involved in data acquisition is minimal and researchers can acquire imagery according to their schedule and convenience. We discuss significant glaciological studies involving UAV as remote sensing platforms. This is the first review work, exclusively dedicated to highlight UAV as a remote sensing platform in glaciology. We examine polar and alpine applications of UAV and their future prospects in separate sections and present an extensive reference list for the readers, so that they can delve into their topic of interest. Because the technology is still widely unexplored for snow and glaciers, we put a special emphasis on discussing the future prospects of utilising UAVs for glaciological research. © 2015 Elsevier Inc.
