Synthesis and Photoluminescence of Silole Derivatives
Sharma, Arun Kumar,Lee, Sung-Gi,Um, Sungyong,Cho, Bomin,Sohn, Honglae The Basic Science Institute Chosun University 2013 조선자연과학논문집 Vol.6 No.3
The syntheses of 9,9'-spiro-9-silabifluorene as well as 1,1-dichloro-1-silafluorene and 1,1-dimethyl-1-silafluorene through the formation of 2,2'-dibromobiphenyl have been emphasized with good yields. Their fluorescence spectra are obtained using photoluminescence spectrometer and assumed to be the precursors of the development of polymers.

Developmental regulation and effect of abiotic stresses (osmotic, salt, heat, and drought) on induction of boiling-stable acid phos-phatases (BsAPases) was studied in the growing wheat seedlings. SDS-PAGE revealed the induction of several boiling-stable polypeptides in a spatial and temporal manner in the growing seedlings. Western blot analysis, using polyclonal acid phosphatase antiserum, revealed the induction of a cross-reacting one 14 kDa boiling-stable acid phosphatase band (14 kDa, BsAPase14) in endosperm at 7 and 14 days of germination (DOG). Various abiotic stresses (heat, salt, and osmotic) also elicit accumulation of BsAPase14 in a tissue-dependent manner. Imposition of drought stress also resulted in an induction of boiling-stable protein (BsAPase-14) which disappeared after removing the stress. Based upon these observations, the possible role of BsAPase14 in water-stress tolerance is discussed.

Objective: The use of non-platinum drugs in concurrent chemoradiation in carcinoma cervix has not been well explored and hence a two arm study was planned to compare the outcome of concomitant cisplatin or gemcitabine in locally advanced carcinoma cervix. Methods: Thirty six patients were evaluated in this study for response rates and complications. These patients were divided into two arms, sixteen patients in the cisplatin arm and twenty patients in the gemcitabine arm. Cisplatin and gemcitabine were given as i.v. infusion at doses of 40 mg/㎡ and 150 mg/㎡ respectively for five weeks concomitant with radiotherapy. All patients had received pelvic radiotherapy to a dose of 50 Gy/25 fraction/5 weeks by four field box technique followed by high-dose-rate brachytherapy (3 sessions, each of 7.5 Gy to point A). Results: Median follow up was of 10.4 months (range, 3 to 36 months) and 10.9 months (range, 2 to 49 months) in the cisplatin and gemcitabine arms, respectively. At first follow up, 68.8% in the cisplatin arm and 70% in the gemcitabine arm had achieved complete response (p=0.93). Similar response rates were noted in different stages in both arms. None of the patients except one developed grade 4 toxicity. Similar toxicity profiles were observed in both arms. Local disease control, distant disease free survival and overall survival was 68.8% vs. 70%, 93.8% vs. 85%, 68.8% vs. 60% in the cisplatin and gemcitabine arms, respectively. Conclusion: Weekly gemcitabine had similar disease control and tolerable toxicity profile with cisplatin. Gemcitabine may be used as an alternative to cisplatin in patients with compromised renal function.

TP53 Polymorphisms in Sporadic North Indian Breast Cancer Patients
Sharma, Sarika,Sambyal, Vasudha,Guleria, Kamlesh,Manjari, Mridu,Sudan, Meena,Uppal, Manjit Singh,Singh, Neeti Rajan,Bansal, Darpan,Gupta, Arun Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.16
Background: The purpose of this study was to evaluate the potential association of five (p.P47S, p.R72P, PIN3 Ins16bp, p.R213R and r.13494g>a) polymorphisms of TP53 with the risk of developing breast cancer in North Indian Punjabi population. Methods: We screened DNA samples of 200 sporadic breast cancer patients (197 females and 3 males) and 200 unrelated healthy, gender and age matched individuals for the polymorphisms. Results: For the p.P47S polymorphism, we observed the PP genotype in 99.5% of the patients and PS genotype in only 1 patient. All the controls had the wild type PP genotype. The frequency of RR, RP and PP genotype of p.R72P was 23.5% vs 33.5%, 51.5% vs 45.5% and 25% vs 21% in patients and controls respectively. Heterozygous (RP) genotype was increased in breast cancer patients as compared to controls (51.5 vs 45.5%) and showed 1.61 fold significantly increased risk for breast cancer (OR=1.61, 95% CI, 1.01-2.58, p=0.04). In breast cancer patients the frequencies of A1A1, A1A2 and A2A2 genotypes of PIN3 Ins16bp polymorphism were 67%, 26% and 7% respectively whereas in controls the genotype frequencies were 68.5%, 27.5% and 4% respectively, with no significant difference. For p.R213R (c.639A>G), all individuals had homozygous wild type genotype. The frequencies of GG, GA and AA genotypes of TP53 r.13494g>a polymorphism were 62 vs 67.5%, 33 vs 28% and 5 vs 4.5% in patients and controls respectively, again without significant difference. We observed that RP-A1A1 genotype combination of p.R72P and PIN3 Ins16bp and RP-GG combination of p.R72P and r.13494g>a polymorphism showed significant risk of breast cancer (OR=1.65, 95%CI: 0.98-2.78, p=0.05; OR=1.72, 95%CI: 1.01-2.92, p=0.04). Conclusion: The results of present study indicated that among the five TP53 polymorphisms investigated, the p.R72P polymorphism, and the RP-A1A1 and RP-GG genotype combination contribute to breast cancer susceptibility in North Indians.

Beyond Growth: Does Tourism Promote Human Development in India? Evidence from Time Series Analysis
SHARMA, Manu,MOHAPATRA, Geetilaxmi,GIRI, Arun Kumar Korea Distribution Science Association 2020 The Journal of Asian Finance, Economics and Busine Vol.7 No.12
The present study aims to investigate the impact of tourism growth on human development in Indian economy. For this purpose, the study uses annual data from 1980 to 2018 and utilizes two proxies for tourism growth - tourism receipt and tourist arrivals - and uses human development index calculated by UNDP. The study uses control variables such as government expenditure and trade openness. The study employs auto regressive distributed lag (ARDL) approach to investigate the cointegrating relationship among the variables in the model. Further, the study also explores the causal nexus between tourism sector and human development by using the Toda-Yamamoto Granger non-causality test. The result of ARDL bounds test reveals the existence of cointegrating relationship between human development indicators, government expenditure, trade openness, and tourism sector growth. The cointegating coefficient confirms a positive and significant relationship between tourism sector growth and human development in India. The causality result suggests that economic growth and tourism have a positive impact while trade openness has a negative impact on human development in India. The major findings of this study suggest that tourism plays an important role in the socio-economic development of Indian economy in recent years and the country must develop this sector to achieve sustainable development.
