Relationships within the Polygonaceae have been recently examined using rbcL sequences, with an emphasis on Polygonum and its segregates. Here we test these results with respect to Polygonum (sensu lato) with an expanded dataset, including additional species and gene regions. Specifically, we focus on inferring the relationships of Eupersicaria (Polygonum sect. Persicaria in many prior treatmen...

Trichorrhexis nodosa is a condition in which individual hairs develop areas where the shaft has split longitudinally into numerous small fibres. The hairs eventually break at these points leaving brush-like ends. Usually trichorrhexis nodosa results from mechanical trauma or harsh chemical treatment (Chernosky and Owens, 1966), but two inherited disorders, argininosuccinic aciduria (Allan et al...

Some Xylaria materials growing on the fruits of Liquidambar spp. were collected. They were identified as X. persicaria on the basis of morphological characteristics and sequence analysis of the complete ITS region (ITS1-5.8S-ITS2) of rDNA. This is the first record of this species from Korea.

POLYARTERITIS nodosa (periarteritis nodosa), first described by Kussmaul and Maier (1866), is a relatively rare disease, but considerable attention has been paid to it in recent years. Duke-Elder (1962), describing the condition, wrote: "this is a disseminated disease of obscure cause characterized by necrosing obliterative lesions of small arteries and arterioles which appear nodular owing to ...

Adjuvant medical treatment steroid therapy of polyarteritis nodosa. Specific treatments are sometimes required. 55: 146–155 renal vasculitis. Angiotensin converting enzyme inhib-10. Guillevin L, Jarrousse B, Lok C et al. Long-term followup after itors or angiotensin II-receptor blockers are effective treatment of polyarteritis nodosa and Churg–Strauss angiitis and able to control severe or mali...

INTRODUCTION Polyarteritis nodosa is a rare disease resulting from blood vessel inflammation (vasculitis), causing damage to organ systems and featuring an extended range of possible symptoms. The cause of polyarteritis nodosa is unknown. CASE PRESENTATION In the present report we describe the presentation and treatment of polyarteritis nodosa involving the hard palate in an 88-year-old Cauca...

The Banc d’Arguin in Mauritania is an area characterised by shallow waters and tidal flats with extensive seagrass beds. The aim of this study was to determine the role of the Banc d’Arguin tidal flats as a habitat and a nursery for shrimps. Shrimps were sampled in the Baie d’Aouatif in the intertidal (ponds, Zostera noltii seagrass beds and bare sediment) with a push net during high and low ti...

INTRODUCTION Hepatitis C virus has been under-recognized as an etiologic factor for polyarteritis nodosa and the presence of hepatitis C antigenemia in patients with polyarteritis nodosa has been reported as insignificant. In the literature hepatitis C virus-associated polyarteritis nodosa is a rare and controversial entity. CASE PRESENTATION A 34-year-old Sri Lankan Tamil man presented to ou...

Seckel syndrome is a rare genetic disorder with a typical "bird-headed" appearance. It could affect many organ systems but renal involvement is uncommon. Polyarteritis nodosa is systemic vasculitic disorder which also involves kidneys. We report a case of Seckel syndrome in a 9 year-old boy with renal involvement due to polyarteritis nodosa. According to the literature, this is the first report...
