Software measurement is a key factor in managing, controlling, and improving the software development processes. Software quality is one of the most important factors for assessing the global competitive position of any software company. Thus the quantification of quality parameters and integrating them into quality models is very essential. Software quality criteria are not very easily measured and quantified. Many attempts have been made to exactly quantify the software quality parameters using various models such as ISO/IEC 9126 Quality Model, Boehm's Model, McCall's model, etc. In this paper an attempt has been made to provide a tool for precisely quantifying software quality factors with the help of quality factors stated in ISO/IEC 9126 model. Due to the unpredictable nature of the software quality attributes, the fuzzy multi criteria approach has been used to evolve the quality of the software.

Rad61/Wpl1 (Wapl), a cohesin regulator, controls chromosome compaction during meiosis

Challa, Kiran,Lee, Min-Su,Shinohara, Miki,Kim, Keun P.,Shinohara, Akira Oxford University Press 2016 Nucleic acids research Vol.44 No.7

<P>Meiosis-specific cohesin, required for the linking of the sister chromatids, plays a critical role in various chromosomal events during meiotic prophase I, such as chromosome morphogenesis and dynamics, as well as recombination. Rad61/Wpl1 (Wapl in other organisms) negatively regulates cohesin functions. In this study, we show that meiotic chromosome axes are shortened in the budding yeast <I>rad61/wpl1</I> mutant, suggesting that Rad61/Wpl1 negatively regulates chromosome axis compaction. Rad61/Wpl1 is required for efficient resolution of telomere clustering during meiosis I, indicating a positive effect of Rad61/Wpl1 on the cohesin function required for telomere dynamics. Additionally, we demonstrate distinct activities of Rad61/Wpl1 during the meiotic recombination, including its effects on the efficient processing of intermediates. Thus, Rad61/Wpl1 both positively and negatively regulates various cohesin-mediated chromosomal processes during meiosis.</P>

Phosphorylation-Driven Assembly of the RIP1-RIP3 Complex Regulates Programmed Necrosis and Virus-Induced Inflammation

Cho, Y.,Challa, S.,Moquin, D.,Genga, R.,Ray, T.D.,Guildford, M.,Chan, F.K.M. Cell Press ; MIT Press 2009 Cell Vol.137 No.6

Programmed necrosis is a form of caspase-independent cell death whose molecular regulation is poorly understood. The kinase RIP1 is crucial for programmed necrosis, but also mediates activation of the prosurvival transcription factor NF-κB. We postulated that additional molecules are required to specifically activate programmed necrosis. Using a RNA interference screen, we identified the kinase RIP3 as a crucial activator for programmed necrosis induced by TNF and during virus infection. RIP3 regulates necrosis-specific RIP1 phosphorylation. The phosphorylation of RIP1 and RIP3 stabilizes their association within the pronecrotic complex, activates the pronecrotic kinase activity, and triggers downstream reactive oxygen species production. The pronecrotic RIP1-RIP3 complex is induced during vaccinia virus infection. Consequently, RIP3<SUP>-/-</SUP> mice exhibited severely impaired virus-induced tissue necrosis, inflammation, and control of viral replication. Our findings suggest that RIP3 controls programmed necrosis by initiating the pronecrotic kinase cascade, and that this is necessary for the inflammatory response against virus infections.

Spermidine alleviates oxidative stress in silk glands of Bombyx mori

Aparna Yerra,Surekha Challa,Satyavathi V. Valluri,Anitha Mamillapalli 한국응용곤충학회 2016 Journal of Asia-Pacific Entomology Vol.19 No.4

Silk gland is a specialized organ for the synthesis of silk. Spermidine is a natural polyamine present in all living cells. It gained attention recently due to its role in longevity and growth promotion. Our earlier study reported enhancement in silk production after spermidine treatment during the 5th instar larval stage of Bombyx mori hybrid strain CSR2 × CSR4. Oxidative stress increases during the degeneration of silk glands in spinning stage. Spermidine plays an important role in relieving oxidative stress. Results showed that exogenous administration of natural polyamine, spermidine, significantly increased the metabolic activity and reduced the oxidative stress of the silk gland in the pre-pupal stage. Expression analysis also confirmed increase in metabolic activity of silk glands after spermidine treatment by showing enhancement inMYC gene expression. Finally, our results demonstrate that supplementation of spermidine enhanced cell viability and decreased oxidative stress of the silk glands. Thiswork also opens up the idea of feeding antioxidants to silkworms which would be beneficial to the sericulture farmers.

Comparative evaluation of the effectiveness of a mobile app (Little Lovely Dentist) and the tell-show-do technique in the management of dental anxiety and fear: a randomized controlled trial

Elicherla, Sainath Reddy,Bandi, Sujatha,Nuvvula, Sivakumar,Challa, Rama subbareddy,Saikiran, Kanamarlapudi Venkata,Priyanka, Vaka Jeevan The Korean Dental Society of Anesthsiology 2019 Journal of Dental Anesthesia and Pain Medicine Vol.19 No.6

Background: Behavior guidance is a technique used to subdue inappropriate behavior by establishing communication that meets the needs of a child. This study aimed to measure the effectiveness of a mobile app (Little Lovely Dentist) compared to the tell-show-do (TSD) technique in managing anxious children during their first dental visit. Methods: Fifty children (30 boys and 20 girls) without any past dental experience, aged from 7 to 11 years, were randomly allocated into either the dental app group or the TSD group. The pre- and post-operative anxiety of children who underwent prophylactic cleaning was assessed both physiologically and subjectively using a heart rate measurement and the RMS pictorial scale, respectively. Results: The intragroup comparison of heart rate and RMS scores for children allocated to the dental app group was statistically significant (P value ≤ 0.001). However, a significant reduction only occurred in the RMS scores, but not the heart rate measurements, in the TSD group. Conversely, there was an increase in heart rates in the TSD group. Conclusion: Educating the child prior to a dental procedure using a smartphone application such as Little Lovely Dentist can significantly alleviate the anticipatory anxiety and engage children in dental treatment during their first visit.

The functional sites of uracil, i.e., CO and NH, played a critical role in the complexation of metals via uracil-quartet functional architectures. Stable metal–uracil complexes significantly affected the growth kinetics, enhancing the uniform delivery of multimetal components into films and suppressing the undesirable formation of CuS particles. CZTS films obtained with the addition of 0.05 and 0.5 M uracil exhibited a smooth surface morphology and significantly improved photoconductive performance.
