background: definite data regarding the incidence and distribution of renal tumours in eastern india is not known. for better management, as it is essential to identify patients with poor prognosis, prognostic factors like stage, nuclear grade and their relationship to molecular markers are also unclear in this region. the purpose of our study was to assess the spectrum of adult renal tumours w...

let $a$ be a non-trivial abelian group and $a^{*}=asetminus {0}$. a graph $g$ is said to be $a$-magic graph if there exists a labeling$l:e(g)rightarrow a^{*}$ such that the induced vertex labeling$l^{+}:v(g)rightarrow a$, define by $$l^+(v)=sum_{uvin e(g)} l(uv)$$ is a constant map.the set of all constant integerssuch that $sum_{uin n(v)} l(uv)=c$, for each $vin n(v)$,where $n(v)$ denotes the s...
Although rectal mucosal labeling index is thought to be a useful surrogate biomarker for colorectal cancer, the ability of the index to predict future neoplasia is unclear. We obtained rectal mucosal biopsies from 333 participants of a randomized controlled chemoprevention trial of calcium supplementation to determine whether labeling index was correlated with concurrent or future colorectal ne...
Proliferative activity of background and neoplastic colonie mucosa was examined following five months of weekly injec tions of 1,2-dimethylhydrazine (20 mg/kg) and one or four months of rest to determine whether previously reported changes may result from an acute or chronic effect of dimethylhydrazine and whether differences exist between stages of neoplasia. To determine whether neoplasia is ...
Several small studies have reported that having a high percentage of breast tumor cells that express the proliferation antigen Ki-67 (ie, a high Ki-67 labeling index) predicts better response to neoadjuvant chemotherapy. However, the predictive value of a high Ki-67 labeling index for response to adjuvant chemotherapy is unclear. To investigate whether Ki-67 labeling index predicts response to ...
A rapid and reproducible method for the preparation of autoradiographs from single-cell suspensions of human tumor cells, including melanoma and lung carcinoma, is described. Tritiated thymidine of high specific activity (6.0 Ci/mmole) was used so that autoradiographs could be developed and read at 24 hr after the sample was taken. Samples were prepared in duplicate, and a Hypaque-Ficoll densit...
Distance compatible set-labeling of a graph G is an injective setassignment f : V (G) → 2X , X a nonempty ground set, such that the corresponding induced function f⊕ : V (G)×V (G) → 2X −{∅}, defined by f⊕(u, v) = f(u) ⊕ f(v) satisfies | f⊕(u, v) |= k (u,v) d(u, v) for all distinct u, v ∈ V (G), where d(u, v) is the distance between u and v, and k (u,v) is a constant, not necessarily an integer;...
Uveal melanoma cell cycling, quantified by bromodeoxyuridine (BrdUrd)-labeling index and mitotic index, is predictive of tumor-related mortality. Serial sections from 36 formalin-fixed melanoma specimens were labeled with BrdUrd and stained with hematoxylin and eosin. All tumors were assessed for the area of highest cell cycling activity and counts for mitotic figures and BrdUrd labeling were p...
