Study Design Case report. Objective Spinal subarachnoid hemorrhage (SSAH) makes up less than 1.5% of all the cases of subarachnoid hemorrhage. Most cases of spontaneous SSAH occur in association with coagulopathy, lumbar punctures, or minor trauma. Idiopathic SSAH is extremely rare with only 17 cases published. Idiopathic SSAH presents a diagnostic dilemma, and the appropriate investigations an...

We evaluated the presence and number of eosinophils at varying stages in the human corpus luteum from 27 ovaries of women at reproductive age. Eosinophils preferentially accumulated in dilated microvessels of the thecal layer transforming into septa of the corpus luteum. The granulosa layer under luteinization, the thecal layer, and haemorrhages in the former antrum each contained low, moderate...

Mammalian ovarian follicular development and atresia is closely regulated by the cross talk of cell death and cell survival signals, which include endocrine hormones (gonadotropins) and intra-ovarian regulators (gonadal steroids, cytokines and growth factors). The fate of the follicle is dependent on a delicate balance in the expression and actions of factors promoting follicular cell prolifera...

We conducted a study to determine the common characteristics of patients who developed radiculopathy symptoms and corresponding heterotopic ossification (HO) from transforaminal lumbar interbody fusions (TLIF) using recombinant human bone morphogenetic protein 2 (rhBMP-2). HO can arise from a disk space with rhBMP-2 use in TLIF. Formation of bone around nerve roots or the thecal sac can cause a...

Calcitonin (CALCA), a hormone primarily known for its role in calcium homeostasis, has recently been linked to reproduction, specifically as a marker for embryo implantation in the uterus. Although CALCA expression has been documented in several tissues, there has been no report of production of CALCA in the ovary of any vertebrate species. We hypothesized that the Calca gene is expressed in th...

The production of plasminogen activator by ovarian granulosa cells has been previously reported to be temporally correlated with ovulation in the rat and to be under hormonal control of gonadotropins. We have examined the type of plasminogen activator produced by granulosa cells and also investigated other ovarian cell types for synthesis of this enzyme. Using antibodies specific for tissue-typ...
