PURPOSE The objective of this study was to determine the phenotypic characterization of ligamentum flavum cells from patients with ossification of the ligamentum flavum (OLF). MATERIALS AND METHODS Ligamentum flavum tissues were harvested from OLF and non-OLF patients during surgery. OLF and non-OLF cells were isolated from explant cultures. Cultured cells were analyzed using immunofluorescen...

Ossification of the ligamentum flavum (OLF) was discovered by Polgar and further described by Yamaguchi and Isuruni [1]. Among the thoracic myelopathies, its incidence is less than that of ossification of the posterior longitudinal ligament (OPLL) and higher than that of herniated nucleus pulposus (HNP) [1]. It is mostly prevalent in Japan and other East Asian countries such as Korea and China ...

The clinical, radiologic, and histologic features of ossification and calcification of the ligamentum flavum were studied in 18 patients. Ossification (15 patients) usually occurred in the lower thoracic spine in men of various ages, while calcification (three patients) was found exclusively in the cervical region of older women. Histologic examinations of ossification showed mature lamellar bo...

The yellow ligament, or Ligamentum flavum, is the ligament that connects lamina arches of two adjacent vertebrae in spine [1,2]. This and has elasticity [3,4]. flavum ossification an uncommon cause pressure on cervical cord [3] [5-7]. commonly occurs thoracic which can myelopathic symptoms patient [8,9]. main this problem unknown, but it when soft tissue calcified causes narrowing spinal canal ...

INTRODUCTION Ossification of the ligamentum flavum (OLF) of the spine is associated with serious neurologic compromise, but the pathomechanism of this process remains unclear. The objective of this study was to investigate the pathomechanism of the ossification process, including the roles of various transcriptional factors in the ossification of human thoracic ligamentum flavum. METHODS Sect...

BACKGROUND We report the first prospective sonoanatomic study in neonates with the aim to perform ultrasonographic-guided epidural catheter placement in this age group. METHOD One hundred forty-five neonates with a body weight < or =4 kg (0.53-4 kg) were included in this prospective study. The study was divided into 3 consecutive parts. In the first part, the neuraxial sonoanatomy of 60 neona...

In this study, female preferences and behavioural isolation were estimated in a pair of allopatric sister species, Etheostoma duryi and Etheostoma flavum. Dichotomous mate preference trials were conducted to determine whether females prefer to associate with conspecific over heterospecific males and free-spawning assays were conducted to determine whether those preferences translated into behav...

Objective. Structures such as ligamentum flavum, annulus, and lamina play an important role in the segmental function. We proposed the surgical technique for achieving the sufficient preservation of segmental structures, in spite of sufficient removal of pathologic disc in the L5-S1 using the ligamentum flavum splitting and sealing technique. Methods. We retrospectively analyzed 80 cases that u...

OBJECTIVE A detailed investigation of the gross and microscopic anatomy of ligamentum flavum. METHODS Material included 14 lumbar vertebral columns obtained from the Anatomy Department, King Faisal University, Dammam during the period between January 2005 and January 2006. Height, width, and thickness of ligamenta flava were measured. A microscopic study was also performed. Computed tomograph...

Charlock (Sinapis arvensis L.) is a serious weed of agriculture, especially in spring sown crops.  Genus Glaucium Mill. belongs to Papaveraceae and members of this genus have several alkaloids in laticiferes. The present research focuses on effects of aquatic extract of Glaucium oxylobum, G. elegans and G. grandiflorum on many physiological factors of Charlock. Laboratory studies were conducted...
