Acral melanoma is commonly diagnosed in people of color and has worse prognosis than cutaneous melanoma, even when controlling for tumor stage. Here, we seek to assess differences mutational profiles acral melanomas, which could potentially impact treatment outcomes. Mutational 1273 patients (118 1155 cutaneous) from the American Association Cancer Research Project Genomics Evidence Neoplasia I...

Irradiation of amorphous a-Se Ag I and a-Se films by linearly polarized He–Neand Arq ion-laser light was shown 70 15 15 to produce polycrystalline films with linear dichroism, the sign of which is determined by the polarization of the light. Photocrystallization of the films was confirmed by direct structural investigations. Thus, a new phenomenon, the effect of light polarization on the photoc...

A total of 917 Mycoplasma isolations were made from 4 092 specimens originating from 2 874 cattle in private herds and at AI stations. The percentages of isolations from the different sources were: cervico-vaginal mucus 14,6%, semen 43%, preputial wash 25%, foetuses 3,3% and placentas 15%. Mycoplasma bovigenitalium, the most common isolate, was recovered from 39% of males, 47% of females, 25% o...

We prove existence, uniqueness, and regularity properties for a solution u of the Bellman-Dirichlet equation of dynamic programming: (1) max {I]u+f i} =0 in (2 i = 1 , 2 u=O on 092, where D and L 2 are two second order, uniformly elliptic operators. The method of proof is to rephrase (1) as a variational inequality for the operator K = L 2 (D)1 in L2(O) and to invoke known existence theorems. F...

OBJECTIVE To study the relationship between bullying behavior and psychopathology. MATERIALS AND METHODS A total of 1 092 students identified their peers' bullying status based on the Bull-S questionnaire. Parents completed the Child Behavior Checklist (CBCL) to determine psychopathology levels. RESULTS The bullying group had associations with anxiety, somatic symptoms, oppositionalism and ...
