Natural products – Discover their challenge and beauty Natural products have always been among the most fascinating objects of the practicing chemist. In fact, in many definitions of chemistry the isolation, purifi cation and structural elucidation of natural products plays a central role. The his t[r]

Influence of substitution of 3d metals for Mn on properties of La0.67Ca0.33Mn0.9 TM0.1O3 (TM = Fe, Co, Ni) compounds was studied. Ferromagnetic – paramagnetic and metals – insulator transitions were significantly affected by Mn-site substitution. However, no observable difference was found in their[r]
Crystalline perovskite La0,67−xLi3xTiO3 with x = 0.06, 0.11 and 0.15 were prepared by solid-state-solution reactions at 1350◦C from TiO2, La2O3 and Li2CO3. Crystalline structure of these compounds was analyzed by XRD method. The ionic conducting property of La0.67−xLi3xTiO3 was characterized on Auto[r]

Abstract The use of anthocyanin as a source of naturaldyes has been increased due to itslack of toxicity. In this study, natural dyes from the mulberry fruits extracted under different operating conditions such as extraction time (2060 min), temperature (4080 0C) and mass of the mulberry (1025 g)[r]
Region wise monitoring of the PPR virus by active surveillance is essential as it aids in strategic planning of measures of disease control and prevention. The North Eastern Karnataka with sizable sheep and goat population experiences the outbreaks of PPR but the attempts to isolate and characterize[r]
RIPK1 (receptor-interacting protein kinase-1) plays a role in cancer development, whereas no clear studies focused on the cervical cancer. The objective of this study was to evaluate the relationship between RIPK1 polymorphisms and cervical cancer risk among the Uyghur population.
Urban green spaces are urban areas which were occurred that, natural or semi natural ecosystems were converted urban spaces by human influence. Urban green spaces provide the connection between urban and nature. In this context, green areas are reflection in the urban spaces of natural or near natur[r]
In this work, LaNi3.55Al0.3Mn0.4Co0.75 compounds were prepared by arc melting method in the Ar atmosphere. The structure and grain size were tested by X-ray diffraction and TEM measurements. Electrochemical properties and battery parameter were carried out by bipotentiostat and battery tester equipm[r]
A major impediment in the treatment of ovarian cancer is the relapse of chemotherapy-resistant tumors, which occurs in approximately 25% of patients. A better understanding of the biological mechanisms underlying chemotherapy resistance will improve treatment efficacy through genetic testing and nov[r]

In the present investigation rice genotype HUR 105 was selected to see the effect of seed priming on the activity of antioxidant enzymes and changes of biochemicalsof rice under timely and late sown conditions. Priming of seeds has been done with distilled water (hydro), Mg(NO3)2 salt (halo), kineti[r]
Familial colorectal cancer type X (FCCTX) is a phenotypically defined subset of hereditary colorectal cancer with unknown and potentially heterogeneous genetic aetiology. FCCTX has been characterized as a colorectal cancer-specific syndrome, which we herein challenge by estimating the risk for extra[r]
In this retrospective study, we evaluated the biochemical recurrence rate, metastatic disease progression, and prostate cancer-specific and overall survival in patients curatively treated with external beam radiotherapy (EBRT) for early prostate cancer (PC).
