Phyllanthus SP a local plant with multiple medicinal properties
No full textThe plants of the genus Phyllanthus (Euphorbiaceae) are distributed in most tropical and subtropical regions of world. This plant has been long used as a traditional medicine to treat problems such as stomach, intestinal infections, kidney and urinary bladder disturbances, diabetes, and hepatitis B. There has been considerable interest in these plants in recent years. This review discusses the antiviral and anticancer aspects of Phyllanthus species. Scientific studies have demonstrated that extracts and purified isolated compounds (flavonoids, lignans, phenols, and terpenes) obtained from these plants possess antiviral effects against herpes simplex (HSV) and dengue virus infections (DENV). These observations are associated with the disruption of essential proteins needed during viral cycle, thus halting the viral replication. In addition, the Phyllanthus species have also been shown to exert inhibitory effects against selected cancers types. In these studies anti-proliferative, anti-metastatic, anti-angiogenic effects and induced apoptosis of human cancers cell lines were observed. These may be explained by the disruption of multiple survival pathways and differential protein expression. CONLCUSION:As a conclusion, tThe Phyllanthus plant possesses multiple medicinal properties, including antiviral and anticancer activities which may potentially be used as a medicinal source for many disease locally

Relativistic charged balls
No full textIt is proven that the relativistic charged ball with its charge less than its mass (in natural units) cannot have a nonsingular static configuration while its radius approaches its external horizon size. This conclusion does not depend on the details of charge distribution and the equation of state. The involved assumptions are (i) the ball is made of perfect fluid; (ii) the energy density is everywhere non-negative.Physics, MultidisciplinarySCI(E)中国科学引文数据库(CSCD)7ARTICLE4571-5763
SYNTHESIS AND X-RAY CRYSTAL-STRUCTURE OF HEXAKIS (MU-(P-TERT-BUTYLTHIOPHENOLATO))-MONO(P-TERT-BUTYLTHIOPHENOLATO) TRICHLORO-TETRACADMATE(II) DIANION
No full textA tetranuclear chlorine-containing cage thiolate cluster complex of cadmium, [HNEt3]2[Cd4(mu-SC6H4Bu(t)-4)6(SC6H4Bu(t)-4)Cl3], consisting of a Cd4(mu-S)6 adamantane-like cage, was synthesized directly from the reaction of a cadmium salt and corresponding thiolate. The chloride ions, introduced unexpectedly, act as terminal ligands.http://gateway.webofknowledge.com/gateway/Gateway.cgi?GWVersion=2&SrcApp=PARTNER_APP&SrcAuth=LinksAMR&KeyUT=WOS:A1994PU27200013&DestLinkType=FullRecord&DestApp=ALL_WOS&UsrCustomerID=8e1609b174ce4e31116a60747a720701Chemistry, Inorganic & NuclearCrystallographySCI(E)4NOTE213023-30261
FORMATION AND X-RAY STRUCTURE OF A NOVEL TETRADECANUCLEAR COPPER(I) CLUSTER COMPLEX CU14(MU-2-S)(SPH)12(PPH3)6
No full textThe neutral tetradecanuclear copper(I) thiolate cluster complex has been formed from the reaction of (Ph3P)2Cu(S2CSPh) with CH2Cl2 and MeOH and structurally characterized by X-ray diffraction analysis. The core of the [Cu14(mu2-S)(SPh)12(PPh3)6] cluster consists of a sulphur ion at the centre of a cube of eight copper(I) atoms form an octahedron and the icosahedron of S12 fits inside the octahedron of Cu.Chemistry, Inorganic & NuclearCrystallographySCI(E)22NOTE232895-28981
Radiation-induced root surface caries restored with glass-ionomer cement placed in conventional and ART cavity preparations: Results at two years
No full textThe document attached has been archived with permission from the Australian Dental Association (8th Jan 2008). An external link to the publisher’s copy is included.Background: There are no published studies comparing the clinical performances of more-viscous glass-ionomer cement (GIC) restorations when placed using conventional and atraumatic restorative treatment (ART) cavity preparation methods to restore root surface caries. Methods: One dentist used encapsulated Fuji IX GP and Ketac-Molar to restore 72 conventional and 74 ART cavity preparations for 15 patients who had received cervicofacial radiation therapy. Two assessors evaluated the restorations at six, 12, and 24 months for retention, marginal defects and surface wear, and recurrent caries. Results: After two years, the cumulative restoration successes were 65.2 per cent for the conventional and 66.2 per cent for the ART cavity preparations, without statistical or clinical significance (P>0.50). Restoration dislodgement accounted for 82.8 per cent and marginal defects for 17.2 per cent of all failures. There were no instances of unsatisfactory restoration wear or recurrent caries observed. Teeth with three or more restored cervical surfaces accounted for 79.3 per cent of all failures (P<0.0001). Conclusions: For root surface caries restored with GIC, the use of hand instruments only with the ART method was an equally effective alternative to conventional rotary instrumentation for cavity preparation. Larger restorations had higher failures, usually from dislodgement.JY Hu, XC Chen, YQ Li, RJ Smales and KH Yi
