    Affinity of estrone on imidazolium-based hydrophobic ionic liquids was computed at the B3LYP/6-31G(d) level. Columbian interactions and other closed-shell interactions, in general, were observed to be pivotal to the binding of the EDC species on visualizing the optimized structures as well as probing the proximity of electronegative and electropositive groups between estrone and ionic liquids. The interaction strength was also studied using calculation of binding energy values of each system. [BMIM]+[PF6]− was found to be the most binding ionic liquid. Estrone was found to be highly bonded in the vicinity of [PF6]− species with a binding energy of −9.57 kcal/mol. The Ionic Liquids under study, [BMIM]+[NTF2]− and [BMIM]+[BF4]−, also illustrated promising binding nature with binding energies of −7.63 and −8.61 kcal/mol. AIM analysis was carried out to validate the nature of intermolecular interactions by calculating the topological properties at (3,−1) bond critical points

    For many industrial machining operations, the quality of surface finish is the prominent requirement. Nevertheless the selection of optimized cutting parameters is very essential for controlling the desired surface quality. Main aim of this attempt is to fix the set of cutting parameters combinations using optimization algorithms. Ant Colony algorithm, Scatter Search algorithm, Genetic algorithm and BAT algorithm were used for various parameters on the surface roughness to arrive a suitable combination of parameters which are optimal to meet the product quality requirement. The effectiveness of the algorithms is ordered based up on the error rate while computing and the best two algorithms are combined for more tuned outcome

    The study's objective is to identify the phytoconstituents and determine the anti-cancer potential of Carica papaya leaves against the MCF 7 cell line. Chloroform, ethyl acetate, and methanol extracts of C. papaya leaves were prepared by cold maceration method and qualitative phytochemical analysis was performed. The anti-proliferative effect of these extracts was determined by 3-(4,5- dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay and apoptotic assay by acridine orange/ethidium bromide staining method on MCF 7 cells.  The effect of the extracts, with different concentrations, on DNA fragmentation, was also performed on MCF 7 cells. Qualitative analysis revealed the presence of alkaloids, flavonoids, terpenoids, steroids, saponins, tannins, glycosides, phenols, anthraquinones, proteins, and carbohydrates. Chloroform, methanol, and ethyl acetate extracts of C. papaya leaves were observed with potential DPPH free radical scavenging activity with 72%, 75%, and 78% respectively. Of these extracts, the chloroform extract (72%) was found to possess a more free radical scavenging effect against DPPH and also showed a dose-dependent effect, the maximum at 100µg/ml, on DNA fragmentation in MCF 7 cells. Further, chloroform extract showed a maximum anti-proliferative effect on MCF-7 cells with IC50 at 22±1.5µg/ml, whereas methanol and ethyl acetate extract at 30±0.5 µg/ml and 28±0.5 µg/ml respectively.  Increased apoptosis in MCF 7 cells was observed with an increased concentration of chloroform extract of C. papaya. From the results of this study, it can be concluded that leaf extract of C. papaya found to possess an anti-proliferative effect and antioxidant potential and it could be due to the presence of rich secondary metabolites of the plant

    Get PDF
    The term Scheuthauer-Marie-Sainton syndrome is also known as cleidocranial dysplasia or cleidocranial dystosis and is derived from ancient greek words cleido (collar bone), knanion (head) and dysplasia (abnormal formation). It is an uncommon but well known genetic skeletal condition and an autosomal dominant malformation affecting bones and teeth. The most common skeletal and dental abnormalities in affected individuals are hypoplastic/ aplastic clavicles, open frontanelles, short stature, retention of primary teeth, delayed eruption of permanent teeth, supernumerary teeth and multiple impacted teeth. Affected person have a characteristic facial appearance with a bulky forehead, hypertelorism and midfacial hypoplasia. General health is usually good and the intellect is unimpaired. This article describes clinical and radiographic features of Scheuthauer-Marie-Sainton syndrome in a 29 years old male patien
