The development of new techniques for the detection of ovarian antibodies has challenged early concepts about the rarity of ovarian antibodies in idiopathic premature ovarian failure (POF), but few attempts have been made to compare results between assays. We have sought to define the prevalence of ovarian autoimmunity in a group of 30 idiopathic POF patients compared to a group of 12 patients ...

BACKGROUND Premature ovarian failure (POF) is characterized by elevated gonadotrophins and amenorrhea before the age of 40 years and occurs approximately in 1% of women. POF etiology is highly heterogeneous with a wide spectrum of etiological pathogenic mechanisms including genetic causes. These mostly involve numerical, structural or monogenic defects on the X-chromosome. Mutations in a small ...

OBJECTIVE Few data are available on the potential role of inflammatory mediators and T lymphocytes in persistent organ failure (POF) in acute pancreatitis (AP). We conducted a retrospective study to characterize their role in the progression of POF in AP. METHODS A total of 69 AP patients presented within 24 hours from symptom onset developing organ failure (OF) on admission were included in ...

BACKGROUND To evaluate the predictive value of serum albumin (ALB) for persistent organ failure (POF) in acute pancreatitis (AP). METHODS We selected 158 patients with AP in this retrospective study from Jan.1st, 2015 to Dec.31st, 2015. Forty-six patients were diagnosed with POF. All the values of laboratory parameters were measured upon admission to hospital. And 48 h after admission, we exa...

BACKGROUND & OBJECTIVES Premature ovarian failure (POF) is defined as the cessation of ovarian function under the age of 40 yr and is characterized by amenorrhoea, hypoestrogenism and elevated serum gonadotrophin levels. The cause of POF remains undetermined in majority of the cases. This study was aimed to investigate the type and frequency of cytogenetic abnormalities in patients with idiopat...

Introduction: Peripheral ossifying fibroma (POF) is a common solitary gingival overgrowth thought to arise from the gingival corium, periosteum and periodontal ligament (PDL). Commonly used synonyms for POF include calcifying fibroblastic granuloma, peripheral fibroma with calcification, peripheral cementifying fibroma, and calcifying or ossifying fibrous epulis. Case Report: This article prese...

A doped poly(methyl methacrylate) (PMMA)– based graded-index plastic optical fiber (GI POF) with high mechanical strength is reported for the first time. Although the POF is generally believed to have a good mechanical flexibility even if it has a large-core diameter, such a high mechanical strength has been provided by making the polymer chains in the POF highly oriented in its axial direction...

BACKGROUND X chromosome rearrangements defined a critical region for premature ovarian failure (POF) that extended for >15 Mb in Xq. It has been shown previously that the region could be divided into two functionally distinct portions and suggested that balanced translocations interrupting its proximal part, critical region 1 (CR1), could be responsible for POF through downregulation of ovary e...

Introduction Peripheral ossifying fibroma (POF) is a reactive lesion of the oral cavity, usually seen in the gingiva. As POF occurs usually in the gingiva which is close to the periodontal ligament, origin is thought to be from the periodontal ligament (PDL). However POF is not a counterpart of the central ossifying fibroma but a reactive lesion of the gingiva. POF is commonly seen in the secon...
