0ctogenarians represent the fastest growing group of patients undergoing percutaneous coronary intervention(PCI),now constituting more than one in five patients treated with PCI in real-world practice.[1,2]Comparing coronary lesion characteristics of patients aged<≥80 years to those≥80 years undergoing PCI,the octogenarians have a higher prevalence of calcified and ostial lesions,tortuous coronary anatomy,multi-vessel disease and left main stem(LMS)stenosis.⑶Furthermore,they often have greater ischemic burden than their younger counterparts,suggesting an even greater benefit following revascularization.

This article presents some new results on the class SLMα of functions that are analytic in the open unit disc U = {z ：｜z｜〈 1} satisfying the conditions that f（0） =0, f＇（0）= 1, and α（1＋zf＇＇（z）/f＇（z）＋（1-α）zf＇（z）/f（z）∈p（U）for all z ∈ U, where αis a real number and p（z）=1＋r^2z^2/1-Tz-T^2z^2（z∈ U）. The number T = （1 -√5）/2 is such that T^2 = 1 ＋ T. The class SFLMa introduced by J. Dziok, R.K. raina, and J. Sokot [3, Appl. Math. Comput. 218 （2011）, 996-1002] is closely related to the classes of starlike and convex functions. The article deals with several ideas and techniques used in geometric function theory and differential subordinations theory.

In the present paper, the authors introduce a new integral transform which yields a number of potentially useful （known or new） integral transfoms as its special cases. Many fundamental results about this new integral transform, which are established in this paper, in- clude （for example） existence theorem, Parseval-type relationship and inversion formula. The relationship between the new integral transform with the H-function and the H-transform are characterized by means of some integral identities. The introduced transform is also used to find solution to a certain differential equation. Some illustrative examples are also given.

Gentiana kurroo, a potent bitter drug plant of Indian subcon- tinent, is under threat due to over exploitation and destruction of natural habitat. We studied the murphophenology and chromosomes of G. kurtoo on both wild and field grown plants, which is very important for proper identification, conservation and domestication. Results reveal that G. kurroo is a perennial herb, and its shoot is represented by flowering branches only. Stem is modified to rhizome. The older rhizomes split into four parts at collar region appearing to fuse together at the ends and is an important diagnostic feature for crude raw materials. Two types of leaves i.e. radical leaves at the base of the plant and canline leaves on flowering shoot are present. Flowering occurs during September to October with 1-9 inflorescences per plant. Inflorescence is terminal monoca- sial cysome type. Mowers are protrandus. Anthesis starts around 7.30 am and continued till 10.0 am. Ovary is bicarpillary syncarpous unilocular. Fruit is Capsule and takes 18-20 days to mature after fertilization. Seeds are very small elliptical and 1 000 seeds weigh to 0.1275 g. Chromosomal studies made by usual squash method reveals the species is a genomic allotetreploid with n = 13. The anaphase-I segregation was normal and in none of the cells at Anaphase-I or Telophase-I could any abnor- mality like laggards, bridges, micronuclei etc. be observed.

Frequency and scale of the blasting events are increasing to boost limestone production. Mines areapproaching close to inhabited areas due to growing population and limited availability of land resourceswhich has challenged the management to go for safe blasts with special reference to opencast *** study aims to predict the distance covered by the flyrock induced by blasting using artificial neuralnetwork （ANN） and multi-variate regression analysis （MVRA） for better assessment. Blast design andgeotechnical parameters, such as linear charge concentration, burden, stemming length, specific charge,unconfined compressive strength （UCS）, and rock quality designation （RQD）, have been selected as inputparameters and flyrock distance used as output parameter. ANN has been trained using 95 datasets ofexperimental blasts conducted in 4 opencast limestone mines in India. Thirty datasets have been used fortesting and validation of trained neural network. Flyrock distances have been predicted by ANN, MVRA,as well as further calculated using motion analysis of flyrock projectiles and compared with the observeddata. Back propagation neural network （BPNN） has been proven to be a superior predictive tool whencompared with MVRA. 2014 Institute of Rock and Soil Mechanics, Chinese Academy of Sciences.

OBJECTIVES To verify whether incomplete revascularisation(IR),quantified using the rSYNTAX(Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery)score andΔSYNTAX%score,could predict short-(in-hospital mortality)and long-term outcomes(12-month mortality)in octogenarians undergoing percutaneous coronary intervention(PCI).METHODS&RESULTS A retrospective analysis of 665 consecutive octogenarian patients presenting for PCI to a UK centre was *** baseline SYNTAX and rSYNTAX scores were assessed from angiographic images.ΔSYNTAX%score was calculated(ΔSYNTAX%=((SYNTAX-rSYNTAX)/SYNTAX)×100%))to measure the relative completeness of ***-Meier analysis assessed survival at 12 months by tertiles of rSYNTAX andΔSYNTAX%***ΔSYNTAX%score was associated with reduced in-hospital mortality(P=0.017),and improved survival benefit(log rank 14.8,P=0.001)at 12 *** Enhancing the completeness of revascularisation in octogenarians selected to undergo PCI is associated with a lower in-hospital mortality and a survival benefit at 12 months.
