Melatonin transduces the effect of day length on LH secretion by acting on the hypothalamus. However, the precise hypothalamic site is unknown. Two studies were undertaken to clarify where melatonin acts in the hypothalamus. Using autoradiographic methods, the hypothalami of 5 ewes were screened to determine whether specific regional densities in melatonin binding existed. A higher density of b...

By means of airborne multiple camera imaging system, we can acquire vertical and oblique aerial images (VAI and OAI) at the same time. In addition to the reduction of data cost, the OAI can also strengthen the imaging geometry during aerial triangulation and be applied on automatic façade texture mapping. With the development of image matching technique, instead of airborne laser scanning (ALS)...

BACKGROUND The study aimed to prospectively observe the clinical and neuroimaging features of pontine infarction with pure motor hemiparesis (PMH) or hemiplegia at early stage. METHODS In 118 consecutive selected patients with the first-ever ischemic stroke within 6 hours after onset, fifty of them presented with PMH or hemiplegia and had negative acute computed tomography (CT) scans, then ma...

Purpose – In January 2002, the National Science Council of Taiwan launched a National Digital Archives Program (NDAP) and has proceeded with the implementation of a system related to the open archives initiative (OAI) framework. This paper aims to introduce the protocol and the prototype system of the project. Design/methodology/approach – A general review of the project. Findings – The OAI int...

Progressive macular hypomelanosis (PMH) is a common skin disorder that causes hypopigmentation in a variety of skin types. Although the underlying aetiology of this condition is unclear, there is circumstantial evidence that links the skin bacterium Propionibacterium acnes to the condition. We now describe the first detailed population genetic analysis of P. acnes isolates recovered from paired...

Posterior Mediastinal Hematomas (PMHs) secondary to a fall from standing height are uncommon, with only one previous case reported in the literature. We describe a case of a 78-year-old male with multiple medical comorbidities, who was transferred to Montreal General Hospital (MGH) with a posterior mediastinal hematoma (PMH) after sustaining a fall from standing height. On initial assessment, t...

myelography is a diagnostic procedure to indicate spinal defects. after the inception of new means of spinal cord imaging, use of myelography has been limited. since there are contraindications for other modalities in some patients, we have to use myelography. the most common complication of myelography is post myelography headache (pmh). many methods have been proposed to alleviate the pain. i...

BACKGROUND Progressive macular hypomelanosis (PMH) is a disease of unclear etiology. Propionbacterium acnes (P. acnes) was claimed to be an etiological factor. OBJECTIVES The purpose of this study was to document the clinicopathological features of PMH in Egyptian patients and to evaluate the therapeutic outcome. METHODS Patients with clinical features of PMH were recruited. Wood's lamp exa...

FeDCOR (Federation of DSpace using CORDRA) is a registry-based federation system for DSpace instances. It is based on the CORDRA model. The first article in this issue of D-Lib Magazine describes the Advanced Distributed Learning-Registry (ADL-R) [1], which is the first operational CORDRA registry, and also includes an introduction to CORDRA. That introduction, or other prior knowledge of the C...
