an injective map f : e(g) → {±1, ±2, · · · , ±q} is said to be an edge pair sum labeling of a graph g(p, q) if the induced vertex function f*: v (g) → z − {0} defined by f*(v) = (sigma e∈ev) f (e) is one-one, where ev denotes the set of edges in g that are incident with a vetex v and f*(v (g)) is either of the form {±k1, ±k2, · · · , ±kp/2} or {±k1, ±k2, · · · , ±k(p−1)/2} u {k(p+1)/2} accordin...

Heme oxygenase catalyzes the oxidative cleavage of protoheme to biliverdin, the first step of heme metabolism utilizing O(2) and NADPH. We determined the crystal structures of rat heme oxygenase-1 (HO-1)-heme and selenomethionyl HO-1-heme complexes. Heme is sandwiched between two helices with the delta-meso edge of the heme being exposed to the surface. Gly143N forms a hydrogen bond to the dist...

background: here we describe a new case of partial distal 10q trisomy in a 6-year-old iranian girl from healthy parents with mental, growth, and psychomotor retardations. methods: additional clinical features include dysmorphic craniofacial features, microcephaly, bilateral hydronephrosis without heart problems, small and rotated low-set ears, bow-shaped mouth, abnormal teeth, short neck, and a...

anatomically precontoured locking plates are intended to facilitate the fixation of articular fractures and particularly those associated with osteoporosis. fractures of the distal humerus are relatively uncommon injuries where operative intervention can be exceptionally challenging. the distal humeral trochlea provides a very narrow anatomical window through which to pass a fixed-angle locking...

‎let $g$ be a graph and $chi^{prime}_{aa}(g)$ denotes the minimum number of colors required for an‎ ‎acyclic edge coloring of $g$ in which no two adjacent vertices are incident to edges colored with the same set of colors‎. ‎we prove a general bound for $chi^{prime}_{aa}(gsquare h)$ for any two graphs $g$ and $h$‎. ‎we also determine‎ ‎exact value of this parameter for the cartesian product of ...

To elucidate role of the dermomyotome in the formation of the axial skeleton, we performed extirpation and transplantation experiments on the dermomyotomes in chick and quail embryos. When the thoracic dermomyotomes of chick embryos were removed, the intercostal muscles and the distal ribs were deficient, while the proximal ribs were more or less normal. Quail tissues including the dermomyotome...

RhoA and RhoC GTPases share 92% amino acid sequence identity, yet play different roles in regulating cell motility and morphology. To understand these differences, we developed and validated a biosensor of RhoC activation (RhoC FLARE). This was used together with a RhoA biosensor to compare the spatio-temporal dynamics of RhoA and RhoC activity during cell protrusion/retraction and macropinocyt...

This is a report on the technique of neoglans reconstruction in a patient with amputated glans penis following guillotine neonatal circumcision. A 4 cm long and 2 cm wide lower lip oral mucosa graft was harvested and used to graft the distal 2 cm of the corporal bodies after 2 cm of the distal penile skin had been excised. One edge of the lower lip oral mucosa graft was anastomosed to the ureth...

The humeroulnar joint is a uniaxial, diarthrodial modified hinge joint. Motion ranges from 0° to 150° and occurs through a rotational axis in the center of the trochlea, in the coronal plane. At the extremes of flexion and extension, limited degrees of internal and external rotation are present (1). The distal humerus has two components-the trochlea medially and the capitellum laterally. Diagra...
