Phase diagram and thermal properties of organic analogues of nonmetal-nonmetal systems
(Springer Netherlands, 2016) Rai, R.N.; Pandey, Priyanka; Rai, U.S.
The solid-liquid phase equilibrium data on three binary organic systems, namely 4-hydroxy benzaldehyde (HB)-2-methyl-4-nitro aniline (MNA), 3-hydroxy-4-methoxybenzaldehyde (HMB)-2-chloro-4-nitroaniline (CNA) and 4-aminobenzophenone (ABP)-m-nitrobenzoic acid (NBA), determined by the thaw-melt method, show the formation of a eutectic at 0.60 mol fraction of HB, 0.48 mol fraction of HMB and 0.51 mol fraction of ABP. These systems are organic analogue of nonmetal-nonmetal system. The values of enthalpy of fusion of eutectics and parent components were determined by the DSC method. Using the heat of fusion values, entropy of fusion, heat of mixing, excess thermodynamic functions and Jackson's roughness parameter were calculated. The negative values of enthalpy of mixing in each case suggest the associative interaction between the molecules of the eutectic melt. The positive value of excess free energy for HB-MNA system indicates the associative interaction between like molecules, while the negative values of excess free energy for HMB-CNA and ABP-NBA indicate the associative interaction between unlike molecules. © 2015 Akadémiai Kiadó, Budapest, Hungary.
Involvement of Cyclin-Dependent Kinase 1 during Postovulatory Aging-Mediated Abortive Spontaneous Egg Activation in Rat Eggs Cultured in Vitro
(Mary Ann Liebert Inc., 2016) Prasad, Shilpa; Koch, Biplob; Chaube, Shail K.
Freshly ovulated rat eggs do not remain arrested at metaphase II (MII) and undergo exit from MII arrest with initiation of extrusion of the second polar body (PBII), a characteristic feature of abortive spontaneous egg activation (SEA). The biochemical and molecular changes during postovulatory aging-mediated abortive SEA remain poorly understood. We investigated the morphological, cellular, and molecular changes during postovulatory aging-mediated abortive SEA in eggs cultured in vitro. Our results suggest that postovulatory egg aging in vitro induced initiation of PBII extrusion in a time-dependent manner. Postovulatory aging increased Wee1 kinase and Thr-14/Tyr-15 phosphorylated cyclin-dependent kinase 1 (Cdk1) levels, whereas Thr-161 phosphorylated Cdk1 and cyclin B1 levels were significantly decreased in eggs cultured in vitro. The early mitotic inhibitor 2 (Emi2) level was significantly reduced, but anaphase promoting complex/cyclosome (APC/C) and mitotic arrest deficient protein (MAD2) levels were increased initially and then reduced during a later period of in vitro culture. These results suggest that an increased Wee1 kinase level modulated the specific phosphorylation status of Cdk1, increased Cdk1 activity, and decreased the cyclin B1 level. Furthermore, the decreased Emi2 level was associated with an increased level of APC/C and decreased level of cyclin B1, which resulted in maturation promoting factor (MPF) destabilization and finally led to postovulatory aging-mediated abortive SEA in rat eggs cultured in vitro. © Copyright 2016, Mary Ann Liebert, Inc.

We report results from the first search for νμ→νe transitions by the NOvA experiment. In an exposure equivalent to 2.74×1020 protons on target in the upgraded NuMI beam at Fermilab, we observe 6 events in the Far Detector, compared to a background expectation of 0.99±0.11(syst) events based on the Near Detector measurement. A secondary analysis observes 11 events with a background of 1.07±0.14(syst). The 3.3σ excess of events observed in the primary analysis disfavors 0.1π<δCP<0.5π in the inverted mass hierarchy at the 90% C.L. © 2016 American Physical Society.
On Q-sobriety
(Taylor and Francis Ltd., 2016) Singh, Sheo Kumar; Srivastava, Arun K.
The study of fixed-basis variety-based topology was initiated by S.A. Solovyov (in 2008), which, among other things, generalizes fuzzy topology. We extend within this framework, an earlier result due to Srivastava et al. (in 1998), which showed that the category of sober fuzzy topological spaces is the epireflective hull of the fuzzy Sierpinski space in the category of T0-fuzzy topological spaces. © 2016 NISC (Pty) Ltd.
Long-term follow up of single-stage anterior cruciate ligament reconstruction and high tibial osteotomy and its relation with posterior tibial slope
(Springer Verlag, 2016) Arun, G.R.; Kumaraswamy, Vinay; Rajan, David; Vinodh, K.; Singh, Ashutosh Kumar; Kumar, Pradeep; Chandrasekaran, Karthik; Santosh, Sahanand; Kishore, Chandan
Background: Open-wedge high tibial osteotomy is considered to be an effective treatment for medial compartmental osteoarthritis. It is generally admitted that tibial slope increases after open-wedge high tibial osteotomy and decreases after closing-wedge high tibial osteotomy. Young patients with anterior cruciate ligament (ACL) deficiency along with medial compartment osteoarthritis need a combined procedure of ACL reconstruction along with high tibial osteotomy to regain physiological knee kinematics and to avoid chondral damage. Materials and methods: We retrospectively analysed data from 30 patients who underwent arthroscopic ACL reconstruction along with medial opening-wedge osteotomy from Jan 2004 to June 2012 with a minimum follow up of 2 years. The pre-operative and post-operative posterior tibial slopes were measured. Functional outcome was analysed using clinico-radiological criteria, IKDC scoring and Lysholm score. Results: Post-operative patients improved both clinically and functionally. The patients who had posterior tibial slope >5° decrease, compared to patients who had less <5° decrease, had better functional scores (IKDC and Lysholm score), which was statistically significant (p < 0.05). Conclusion: Our study has shown that decreasing the tibial slope >5° compared to pre-operative value has functionally favourable effect on the reconstructed ACL graft and outcome. It is known that increasing slope causes an anterior shift in tibial resting position that is accentuated under axial loads. This suggests that decreasing tibial slope may be protective in an ACL deficient knee. Hence by placing the tricortical graft posterior to midline in the opening wedge reduces the posterior tibial slope and thereby reduces the stress on the graft leading to better functional outcome. © 2015, Springer-Verlag Berlin Heidelberg.
