Photoperiod sensitive genetic male sterile (PGMS) rice is sterile mutant controlled by photoperiod. A PGMS mutant 920S was sterile grown under long-day (LD) photoperiod (14 h light/10 h dark) but fertile grown under short-day (SD) photoperiod (10 h light/14 h dark). Proteome analysis revealed that 12 protein spots were differentially expressed in the spikelets of 920S plants either treated with LD or SD photoperiod. Among these proteins, three proteins including chlorophyll a/b binding protein, vacuolar ATPase ${\beta}-subunit,\;{\alpha}-tubulin$ and an unknown protein were more than three-fold abundant in the spikelet of the SD-treated plants than those of the LD-treated plants. On the other hand, eight proteins including acetyl transferase, 2, 3- biphosphoglycerate, aminopeptidase N, pyruvate decarboxylase, 60S acidic ribosomal protein and three unknown protein spots were more abundant in the spikelets of the LD-treated plants than those of the SD-treated plants. The results suggest that the observed proteins may be involved in sterile or fertile pollen development under LD or SD photoperiod respectively in the PGMS mutant rice.

Pandeya, Dipendra Raj,Mittal, Ankush,Sathian, Brijesh,Bhatta, Bibek Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.2

Aim: To investigate the effect of hyperglycemia and hyperinsulinemia on prostate cancer risk. Materials and Methods: This hospital based study was carried out using data retrieved from the register maintained in the Department of Biochemistry of a tertiary care hospital of Kathmandu, Nepal between $31^{st}$ December, 2011 and $31^{st}$ October, 2013. The variables collected were age, serum cholesterol, serum calcium, PSA, fasting blood glucose, serum insulin. Analysis was performed by descriptive statistics and testing of hypothesis using Excel 2003, R 2.8.0, Statistical Package for the Social Sciences (SPSS) for Windows Version 16.0 (SPSS Inc; Chicago, IL, USA) and the EPI Info 3.5.1 Windows Version. Results: Of the total 125 subjects enrolled in our present study, 25 cases were of PCa and 100 were healthy controls. The mean value of fasting plasma glucose was 95.5 mg/dl in cases of prostatic carcinoma and the mean value of fasting plasma insulin was $5.78{\mu}U/ml$ (p value: 0.0001*). The fasting insulin levels ${\mu}U/ml$ were categorized into the different ranges starting from ${\leq}2.75$, >2.75 to ${\leq}4.10$, >4.10 to ${\leq}6.10$, > $6.10{\mu}U/ml$. The maximum number of cases of prostatic carcinoma of fasting insulin levels falls in range of > $6.10{\mu}U/ml$. The highest insulin levels (> $6.10{\mu}U/ml$) were seen to be associated with an 2.55 fold risk of prostatic carcinoma when compared with fasting insulin levels of (< $2.75{\mu}U/ml$). Conclusions: Elevated fasting levels of serum insulin appear to be associated with a higher risk of prostate cancer.

Synthesis and Anti-Inflammatory and Analgesic Activities of 2,4-Di-n-butyl-3,5-diarylimino-1,2,4-thiadiazolidines

Pandeya, S.N.,Naik, P.R.,Singh, S.,Singh, P.N. The Pharmaceutical Society of Korea 1991 Archives of Pharmacal Research Vol.14 No.1

Ten 1,2,4-thiadiazolidines were synthesized and screened for their anti-inflammatory and analgesic activities. Butyl isothiocyanate was used as a starting material. Several compounds showed significant anti-inflammatory and analgesic activities. The unsubstituted and o-methyl, p-acetoxy and o-chloro substituted compounds were found to be more potent anti-inflammatory and analgesic agents than the other compounds.

Domestic Cat Sound Classification Using Transfer Learning

Pandeya, Yagya Raj,Lee, Joonwhoan Korean Institute of Intelligent Systems 2018 INTERNATIONAL JOURNAL of FUZZY LOGIC and INTELLIGE Vol.18 No.2

The domestic cat or house cats (Felis catus) are an ancient human pet animal that can deliver various alert message to human on environmental changes by its mysterious kinds of sounds generation capability. Cat sound classification using deep neural network had scarcity of labeled data, that impelled us to make CatSound dataset across 10 categories of sound. The dataset was even not enough to select data driven approach for end to end learning, so we choose transfer learning for feature extraction. Extracted feature are input to six various classifiers and ensemble techniques applied with predicted probabilities of all classifier results. The ensemble and data augmentation perform better in this research. Finally, various results are evaluated using confusion matrix and receiver operating characteristic curve.

Analysis of Natural Mutant of Photoperiod Sensitive Genetic Male Sterile Japonica 920S under Different Photoperiods in Rice

Devendra Pandeya,서학수,강상구,Uck-Kee Baek 한국육종학회 2006 한국육종학회지 Vol.38 No.5

Photoperiod sensitive genetic male sterile (PGMS) rice 920S was characterized as sterile when it was grown under longday condition but fertile when grown under short day condition. PGMS rice 920S, F1 and F2 plants were examined for their fer-tilities under diferent photoperiods. All 920S parent plants were fertile in short photoperiod condition at 10 hrs day length, partialfertile in intermediate photoperiod condition at 13 hrs day length and sterile in long photoperiod condition at 14 hrs day length.antsshowed wide range of fertility with partial segregation of complete fertile, partial fertile, and complete sterile plants when theywere exposed to intermediate day length condition of 13 hrs day length. Therefore, here we suggest that there is a critical pho-toperiod to affect a PGMS gene that causes an alteration in fertility.

The question of equal representation of citizens in the legislature of Nepal: rhetoric and reality

Ganesh Prasad Pandeya,Tatsuo Oyama 서울대학교행정대학원 2019 Asian Journal of Political Science Vol.27 No.1

To what extent the legislature represents the views of all social groups is a central question in multiethnic societies like Nepal. The results from descriptive and inferential statistical analysis of all representatives from 1959 to 2013 show the existence of a prolonged unequal representation of caste/ethnic groups in the legislature of Nepal. A few subgroups of peoples have historically created a ‘creamy layer’ throughout all political systems. Although women and some excluded identities have gained substantial seats in the later period, progress for many groups, particularly historically marginalized ones, has been far too slow. The representation patterns are largely associated with a design of political institutions, such as electoral system and ethnic quotas, as well as the socioeconomic status of a group linked to poverty, wealth, adult literacy, and human development. These findings suggest that the chances of equal representation appear not just to the worth of group effort rather than its ability to influence the political process through power and resources. Thus, reforming political institutions, particularly the electoral systems, and improving the socioeconomic status of women and excluded identities, all of which demand strong political will and commitment, may narrow down inequality in political representation.
