We assessed the extent of the oblique effect (OE) and the meridional orientation effect (MOE) for a chromatic motion task using red/green gratings throughout an 80 degrees visual field. Four different stimulus orientations were tested. Generally, sensitivity to chromatic motion decreased with increasing eccentricity regardless of the visual field meridian. Also, sensitivity was highest for hori...

We construct bosonized vertex operators (VOs) and conjugate vertex operators (CVOs) of Uq(su(2)k) for arbitrary level k and representation j ≤ k/2. Both are obtained directly as two solutions of the defining condition of vertex operators namely that they intertwine Uq(su(2)k) modules. We construct the screening charge and present a formula for the n-point function. Specializing to j = 1/2 we co...

Morphological characteristics of 108 cases of uni- and bilateral aplasia of the vertebral artery (VA) in reports or images of retrospective studies, including one recent case, published between 1967 and 2016 are analyzed. Incidence, gender, persistence of carotid-vertebrobasilar anastomosis (CVBA), associated with other vascular variants, and vascular pathology in each group of uni- and bilater...

Neonatal lupus is a rare disease caused by the transplacental transfer of maternal autoantibodies to the foetus, characterized by transient clinical manifestations such as cutaneous, haematological, and hepatobiliary events or permanent such as congenital heart block. The typical cutaneous manifestations include erythematous, scaly, annular or arched lesions on the face, with slight central atr...

BACKGROUND The condition known as macrocephaly-cutis marmorata telangiectatica congenita syndrome (M-CMTC) is a rare congenital syndrome of unknown etiology characterized by macrocephaly and vascular lesions that have been described as either cutis marmorata or cutis marmorata telangiectatica congenita (CMTC). Most patients also exhibit facial and limb asymmetry; somatic overgrowth; development...

BACKGROUND Cutis marmorata telangiectatica congenita (CMTC) is a sporadic congenital skin vascular abnormality. Significant number of patients has other congenital anomalies. CASE REPORT We report a case of a preterm male newborn with cutis marmorata pattern presented on the skin of the face, right side of front of the trunk, whole back, glutei and both legs. Besides, microretrognatia and asy...
