The current study is the first report that revealed insecticidal effects of lemon (Citrus limon) peel aqueous extract (LFPAE) against common insect pest of rose, aphids (Macrosiphum roseiformis) and for its influence on useful nontarget predators viz., Coccinella septempunctata and Orius laevigatus on rose plants. Effects of LFPAE seemed promising concerning pest and predators of Rosa spp. The LC ESI Q-TOF MS/MS analysis of extract revealed the presence of (L-pipecolic acid, scopoletin, pulegone, γ-terpinene, carvone, menthone, myrcene, limonene, (−)-trans-isopiperitenol, geranial and linalool as active components that may be ascribed to observed effects. Also, some major terpenoids α-pinene, β-pinene, γ-terpinene, menthone, linalool, limonene which are known to be present in lemon were tested for their efficacy. LFPAE did not show any toxicity towards C. septempunctata. However, it was moderately toxic to O. laevigatus. Food choice assays and odor choice assay revealed that there was no significant difference obtained between the percentage of pests/predators that reached a particular choice (LFPAE treated, or untreated rose leaves). According to LC50 values of LFPAE for aphids, the highest toxicity and least value (6.68 mg/ml), was obtained at 72 h which was almost similar to the lowest concentration tested (×6 =6.25 mg/ml). Besides at 24 and 48 h LC50 values were somewhere around ×2 (100 mg/ml) and ×3 (50 mg/ml) concentrations. Among all the terpenoids tested at 24–72 h, γ-terpinene was most toxic with LC50 value ranging from 0.18 to 0.004 mg/ml followed by menthone (0.8–0.008), β-pinene (5.8–0.004), limonene (5.8–0.009), mixture (8.5–0.003), linalool (12.3–0.13) and α-pinene (17.8–0.02), respectively. Field data showed that LFPAE at ×1 (200 mg/ml), ×2 and ×3 concentration was effective until nine days after treatment (DAT) and lowest concentration ×4 did not show affectivity beyond seven days. However, terpenoids mixture at ×1 (10 mg/ml each) showed affectivity till 11DAT and lower two concentrations (×2 and ×3) caused significant mortality up to 7DAT.

Garima Gupta,Rakesh Kumar,Rachna Rani,Rashmi Sachdeva 대한수학회 2022 대한수학회보 Vol.59 No.2

We define an almost Norden submersion (holomorphic and semi-Riemannian submersion) between almost Norden manifolds and \linebreak show that, in most of the cases, the base manifold has the similar kind of structure as that of total manifold. We obtain necessary and sufficient conditions for almost Norden submersion to be a totally geodesic map. We also derive decomposition theorems for the total manifold of such submersions. Moreover, we study the harmonicity of almost Norden submersions between almost Norden manifolds and between Kaehler-Norden manifolds. Finally, we derive conditions for an almost Norden submersion to be a harmonic morphism.

Growth and development of ladybird beetle Coccinella septempunctata L. (Coleoptera: Coccinellidae), on plant and animal based protein diets

Garima Gupta,Neelima R. Kumar 한국응용곤충학회 2017 Journal of Asia-Pacific Entomology Vol.20 No.3

Different protein sources from plant and animal origin viz., soybean flour (SF-AD) and soaked soybean (SS-AD), bee pollen (BP-AD), honey bee drone larvae (DL-AD) and frozen aphids (AF-AD) were assessed as an artificial diet of C. septempunctata in comparison to their natural diet live aphids. Highest growth index was obtained with SS-AD (4.05) diet almost similar to control (4.0), followed by SF-AD, BP-AD, DL-AD and AF-AD as 3.8, 2.4, 1.98 and 1.94 respectively. Similarly, data showed that success index of the adults fed on an artificial diet containing soybean (SS-AD =1.03, SF-AD =0.98) was almost similar to control (1.0), whereas the diets containing bee pollen, drone larvae, and frozen aphids was lower than control as 0.83, 0.84 and 0.78, respectively. Protein concentration was highest in live aphid (5.9 μg/ml) diet followed by SS-AD (5.6), SF-AD (5.2), BP-AD (3.4), AFAD (2.2) and DL AD (1.3). The results indicated that soybean based diets were more or equivalently suitable to beetles for their growth and development likewise their natural prey and the efficiency of artificial diets was related to its protein concentration.

Gupta, Garima,Kumar, Rakesh Korean Mathematical Society 2020 대한수학회논문집 Vol.35 No.3

We study totally umbilical real half lightlike submanifolds of indefinite Kaehler manifolds with a quarter-symmetric metric connection. We obtain some conditions for a real half lightlike submanifold of an indefinite Kaehler manifold with a quarter-symmetric metric connection to be a product manifold. We derive the expression for induced Ricci type tensor 𝓡^(0,2) and also obtain conditions for 𝓡^(0,2) to be symmetric.

Garima Kishore,Shashi Ranjan,Anjana Pandey,Sanjay Gupta 한국식품과학회 2010 Food Science and Biotechnology Vol.19 No.5

In the present work, the effect of altitudinal variations on the total phenol, flavonoid, and antioxidant potential of seeds and hull of Tartar buckwheat collected from 15 different locations of Western Himalaya has been investigated. Methanolic and acetonic extracts of seed and hull powder showed significantly increasing amounts of total polyphenol content, and antioxidant potential with rising altitude. Methanolic extract of seed and hull powder were found to have significantly greater polyphenol, and antioxidant potential as compared to acetonic extract. The methanolic seed extract of Inderdhara (3,133 m) showed the maximum total phenolic content 1,651 μg gallic acid equivalent/50 mg of dry weight. The methanolic seed extract of Inderdhara showed the maximum antioxidant activity (77.29±1.2%) and antiradical activity (55.5±0.5%)also. The results of this study exhibited good correlation with total polyphenol and antioxidant potential in all the samples followed by the increasing tendency towards rising altitude.

Founder <i>BRCA1</i> mutations in Nepalese population

Anurag Mehta,Himanshi Diwan,Garima Gupta,Shrinidhi Nathany,Shalini Agnihotri,Surender Dhanda 대한병리학회 2022 Journal of Pathology and Translational Medicine Vol.56 No.4

Background: Founder mutation is a heritable genetic alteration observed with high frequency in a geographically and culturally isolated population where one or more ancestors becomes the forebearer of the altered gene. The current study reports two founder mutations in the <i>BRCA1</i> gene in the Nepalese people.Methods: Germline <i>BRCA</i> testing in all surface epithelial ovarian cancers and the selected case of breast, prostate, and pancreatic cancers has been the standard practice from 2016 to 2021. One thousand one hundred thirtythree probands were screened for germline <i>BRCA</i> variants by next generation sequencing. The variants were classified as per the American Society of Medical Genetics and Genomics recommendations. Pathogenic (class V) and likely pathogenic (class IV) were considered clinically relevant and utilized for cascade screening.Results: Nepalese population made up a subcohort of 5.12% (58/1,133) of probands tested for germline <i>BRCA1/2</i> variants. Twenty-seven of these 58 tested harbored pathogenic genetic alterations in <i>BRCA1/2</i> genes, with 23 being <i>BRCA1</i> mutant. Sixteen of 23 <i>BRCA1</i> mutant cases shared one common pathogenic mutation c.2214_2215insT (p.Lys739Ter) (NM_007294.4). Additionally, a second highly recurrent mutation in <i>BRCA1</i> gene c.5068A>T (p.Lys1690Ter) (NM_007294.4) was noted in six patients from this population.Conclusions: The overwhelming abundance of the above two variants in a geographically confined population confers these two genetic alterations a status of founder mutations amongst the people of Nepal. A more extensive population-based study to reaffirm these findings will help establish a dual site-specific germline testing similar to the “Multisite-3-assay” in Ashkenazi Jews as the primary screening tool, especially in a resource-constrained environment.
