Two new species of plant parasitic nematodes (Tylenchorhynchus quaidi n. sp. and T. tritici n. sp.) from Pakistan are described and illustrated. Tylenchorhynchus quaidi n. sp., from soil around roots of potato (Solanum tuberosum) from an experimental field of NNRC, Karachi, Pakistan, is distinguishable from other species by its peculiar sunken dome-shaped head. Although similar to T. goffarti, ...

A 55-year-old woman was referred to our outpatient clinic because of bilateral papular lesions on her nose from 2 years ego. In clinical examination, we found three symmetrical dome-shaped, skin-colored, asymptomatic papules on both nasal alas. The lesions made the patient's nose to seem larger with eroded edges (figures 1, 2). Examination of nasal mucosa was normal. General physical examinatio...

OBJECTIVES This study aimed to clarify the clinical anatomy of the pulmonary root. BACKGROUND Many descriptions of valvular anatomy have focused on the annulus, leading to varied interpretations of abnormal valves. METHODS Twenty-two heart specimens with isolated pulmonary valvular stenosis were examined to analyze the gross structure of the pulmonary root. For comparison, we examined a nor...

In order to investigate the influence of vocal tract morphology, i.e. different palate shapes, on the acoustic output and its perceptual consequences, we simulated /kVk/-sequences by means of a 2D biomechanical tongue model. Three palate shapes (normal, flat and dome shaped) differing in the coronal and mid-sagittal plane were implemented in the model. We assumed that small articulatory changes...

Drusen, the white yellowish deposits that can be seen in funduscopy, are a hallmark of age-related macular degeneration. Histologically, drusen are believed to be dome-shaped or more confluent lipid accumulations between the retinal pigment epithelium and the choriocapillaries. Recent advances in mouse funduscopy have revealed the presence of drusen-like structures in chemokine knockout animals...
