ABSTRACT
Carotid web is a rare risk factor of ischemic stroke. A total of 32 (0.54%) patients with carotid web were finally diagnosed in 5 943 patients who underwent carotid computerized tomography angiography (CTA) in two hospitals. Only one patient received carotid endarterectomy that pathological findings were fibrous tissue hyperplasia of vascular wall with mucinous degeneration. Stent implantation was administrated in two cases. Among 13 asymptomatic patients, the observational follow-up period was (20.9±12.4) months without strokes. Carotid web is a rare aberration. Asymptomatic patients with carotid web are usually silent. Large sized cohort and long-term follow-up are further needed.

In this paper, a series of novel dithioacetal-naphthalenes were designed and synthesized for plant immunity. Their antiviral activities were evaluated against tobacco mosaic virus (TMV) and cucumber mosaic virus (CMV). The results indicated that most compounds exhibited better activity against CMV than against TMV. These dithioacetal derivatives also displayed good bacterial activity against rice bacterial leaf blight. Among them, compound S16 exhibited relatively good anti-CMV, anti-TMV, and antibacterial activity. Structure-activity relationships indicated that introducing the naphthalene moiety enhanced their activities for plant resistance induction. Therefore, the basic motif of compound S16 could be the most promising candidate for further structural optimization to develop a potential activator for plant resistance induction.
ABSTRACT
We treated 80 patients with recurrent chyluria (68 men and 12 women) by a microsurgical technique since 1978. Transinguinal spermatic lymphangiovenous anastomosis was performed in 64 patients and inguinal lymph node-saphenous vein anastomosis was performed in 16. Followup was 6 months to 11 years in 50 of the former and 12 of the latter patients. Chyluria disappeared completely in 30 (60%) and 8 (66.7%) patients, respectively. In 6 of the former patients (12%) chyluria had disappeared immediately after the operation but it recurred within 1.5 to 3 years. The procedure has the advantage of a superficial operative field, and is simple and less traumatic.
