Rice science 2017年第1期24卷 21-31页

作者： Deepak Kumar VERMA prem prakash SRIVASTAV Agricultural and Food Engineering Department Indian Institute of TechnologyKharagpur 721302India

Awareness on nutritive value and health benefits of rice is of vital importance in order to increase the consumption of rice in daily diet of the human beings. In this study, a total of six aromatic and two non-aromatic rice accessions grown in India were analysed for their nutritional quality attributes including proximate composition, mineral contents and fatty acids. Data with three replications were used to measure Pearson＇s simple correlation co-efficient in order to establish the relationship among various nutritional quality attributes. The result on proximate composition showed that Govind Bhog had the highest moisture（13.57%） and fat（0.92%） content, which signifies its tasty attribute. Badshah Bhog exhibited the highest fibre content（0.85%）, carbohydrate content（82.70%） and food energy（365.23 k Cal per 100 g）. Among the minerals, the higher Ca（98.75 mg/kg）, Zn（17.00 mg/kg） and Fe（31.50 mg/kg） were in Gopal Bhog, whereas the highest Na（68.85 mg/kg） was in Badshah Bhog, the highest K（500.00 mg/kg） was in Swetganga, Khushboo and Sarbati. The highest contents of unsaturated fatty acids viz. oleic acid（49.14%）, linoleic acid（46.99%） and linolenic acid（1.27%） were found in Sarbati, whereas the highest content of saturated fatty acids viz. myristic acid（4.60%） and palmitic acid（31.91%） were found in Govind Bhog and stearic acid（6.47%） in Todal. The identified aromatic rice accessions Gopal Bhog, Govind Bhog and Badshah Bhog and non-aromatic rice accession Sarbati were found nutritionally superior among all eight tested accessions. The nutritional quality oriented attributes in this study were competent with recognized prominent aromatic and non-aromatic rice accessions as an index of their nutritional worth and recommend to farmers and consumers which may be graded as export quality rice with good unique nutritional values in international market.

作者： Sant Sharan Mishra prem prakash Mishra Dept. of Mathematics & Statistics (Centre of Excellence on Advanced Computing) Dr.Ram Manohar Lohia Avadh University Faizabad UP India

In this paper, we mainly aim to compute the optimal inventory in the phase wise supply chain for queued customers in the interval of lower and upper bounds with particular life of the items. Important performance measures such as total optimal cost of the system and total expected delivery have also been computed by applying the dynamic programming and Drichlet theorem. Finally, numerical demonstration and sensitivity analysis have also been presented to gain the better perspective of the model.

Androgen deprivation therapy targeting the androgens/androgen receptor(AR)signaling continues to be the mainstay treatment of advanced-stage prostate *** use of second-generation antiandrogens,such as abiraterone acetate and enzalutamide,has improved the survival of prostate cancer patients;however,a majority of these patients progress to castration-resistant prostate cancer(CRPC).The mechanisms of resistance to antiandrogen treatments are complex,including specific mutations,alternative splicing,and amplification of oncogenic proteins resulting in dysregulation of various signaling *** this review,we focus on the major mechanisms of acquired resistance to second generation antiandrogens,including AR-dependent and AR-independent resistance mechanisms as well as other resistance mechanisms leading to CRPC *** knowledge of resistance mechanisms to AR targeted treatments will lead to additional research on designing more effective therapies for advanced-stage prostate cancer.

Boronic acid-containing diarylpyrimidine derivatives as novel HIV-1NNRTIs: Design, synthesis and biological evaluation

Drug resistance remains to be a serious problem with type Ⅰ human immunodeficiency virus(HIV-1) nonnucleoside reverse transcriptase inhibitors(NNRTIs). A series of novel boronic acid-containing diarylpyrimidine(DAPY) derivatives were designed via bioisosterism and scaffold-hopping strategies,taking advantage of the ability of a boronic acid group to form multiple hydrogen bonds. The target compounds were synthesized and evaluated for their anti-HIV activities and cytotoxicity in MT-4 *** 10 j yielded the most potent activity and turned out to be a single-digit nanomolar inhibitor towards the HIV-1 ⅢB [wild-type(WT) strain], L100 I and K103 N strains, with 50% effective concentration(EC_(50)) values of 7.19–9.85 nmol/L. Moreover, 10 j inhibited the double-mutant strain RES056 with an EC_(50) value of 77.9 nmol/L, which was 3.3-more potent than that of EFV(EC_(50)= 260 nmol/L) and comparable to that of ETR(EC_(50)= 32.2 nmol/L). 10j acted like classical NNRTIs with high affinity for WT HIV-1 reverse transcriptase(RT) with 50% inhibition concentration(IC_(50)) value of 0.1837 μmol/L. Furthermore,molecular dynamics simulation indicated that 10 j was proposed as a promising molecule for fighting against HIV-1 infection through inhibiting RT activity. Overall, the results demonstrated that 10 j could serve as a lead molecule for further modification to address virus-drug resistance.
