BACKGROUND: Diabetes has been reported as a comorbidity of chronic obstructive pulmonary disease (COPD) in Western countries, but it has not been demonstrated in epidemiological reports in Japan. The purpose of this study was to clarify whether the relationship between airflow obstruction and diabetes can be confirmed in a Japanese general population. METHODS: From 2004 to 2006, blood sampling and pulmonary function tests were performed on 3045 people over the age of 40 years in annual health check-ups held in Takahata, Yamagata Prefecture, Japan...

The relationships between changes in choroidal vasculature and the severity of diabetic retinopathy (DR) remain unclear. We assessed choroidal changes in diabetic patients by measuring choroidal vascularity index (CVI) in conjunction with DR stage. In this study, patients with diabetes and healthy controls were retrospectively analyzed. Subjects were divided into seven groups as follows: Healthy controls, no DR, mild/moderate non-proliferative DR (NPDR), severe NPDR, proliferative DR (PDR), panretinal photocoagulation-treated DR, and clinically significant macular edema...

BACKGROUND AND PURPOSE: Aneurysm recurrence is the primary limitation of endovascular coiling treatment for cerebral aneurysms. Coiling is currently quantified by a volumetric porosity measure called packing density (pd). Blood flow through a coil mass depends on the permeability of the coil mass, and not just its pd. The permeability of coil masses has not yet been quantified. Here we measure coil permeability with a traditional falling-head permeameter modified to incorporate idealized aneurysms...

BACKGROUND: Methemoglobin (MetHb) is an oxidized form of hemoglobin. It is a poor transporter of oxygen and is unable to deliver oxygen to the tissue. Globally, drug & toxin induced methemoglobinemia is more common as compared with the congenital form. Methemoglobinemia caused by paint thinner intoxication is rare. Methylene blue is well established as the first-line therapy for severe methemoglobinemia. CASE REPORT: A 25-year old man was brought to the Emergency Department after accidental consumption of paint thinner...

The major structural component of a blood clot is a meshwork of fibrin fibers. It has long been thought that the internal structure of fibrin fibers is homogeneous; that is, the protein density and the bond density between protofibrils are uniform and do not depend on fiber diameter. We performed experiments to investigate the internal structure of fibrin fibers. We formed fibrin fibers with fluorescently labeled fibrinogen and determined the light intensity of a fiber, I, as a function of fiber diameter, D...

There are many differences between the hair from children and that of adult subjects, the hair being thinner, more porous with a different growth rate from the usual 1 cm/month observed in adults. In order to determine whether hair analysis could discriminate between chronic use and acute administration of a drug in children like in adults, we analyzed hair from 18 children aged between 1 day and 15 years in whom the administration of different drugs was known (single therapeutic administration or acute intoxication)...

Atrial fibrillation (AF) is a common arrhythmia that increases patients' risk of stroke, and determining an optimal prevention therapy is a preference-sensitive decision appropriate for shared decision making (SDM). Utilizing community-based focus groups, we explored beliefs and values around options for stroke prevention. Interview transcripts from five independent focus groups were qualitatively assessed and organized into themes. Most participants were taking a blood thinner (93%) and more than half of participants (64%) reported having AF...

BACKGROUND: Lost joint range of motion (ROM) is common in chronic osteoarthritis, alters regional weight-bearing across the articular surfaces, and contributes to loss of cartilage and bone alterations. Limited data exist on the regional effects on joints subjected to chronic losses of ROM. OBJECTIVE: To characterize the regional replacement by bone as part of articular cartilage degeneration after prolonged immobilization. METHODS: Eleven rat knees were rigidly-immobilized in flexion for 32weeks with contralateral and sham-operated (n=6) knees as controls...

BACKGROUND: Implantation defect is one of these contributing factors for unexplained infertility. In the mid-luteal phase, when implantation is expected to happen, Integrins expression is remarkably increased. So, Integrins could potentially serve as markers for the frame of the window of implantation. αVβ3 integrin could have a role as a potential receptor for embryonic attachment. The aim of the current study is to investigate whether the women with unexplained infertility have a pattern of expression of endometrial αvβ3 integrin that could differ from those who have normal fertility or not...

The platelet-rich fibrin-like matrix (PRFM) is usually prepared onsite and immediately used for regenerative therapy. Nonetheless, to meet the clinical necessity of preserving the PRFM without quality deterioration, we developed a method for preparation of PRFMs from short-term-stored whole blood (WB) samples. In this study, to evaluate the practical expiration date of storage, we extended the storage time of WB samples from 2 to 7 days and assessed the quality of the resulting PRFMs. WB samples collected with acid-citrate-dextrose were stored with gentle agitation at ambient temperature...

The flexible C-terminal parts of fibrinogen's Aα chains named the αC regions have been shown to play a role in fibrin self-assembly, although many aspects of their structure and functions remain unknown. To examine the involvement of the αC regions in the early stages of fibrin formation, we used high-resolution atomic force microscopy to image fibrinogen and oligomeric fibrin. Plasma-purified full-length human fibrinogen or des-αC fibrinogen lacking most of the αC regions, untreated or treated with thrombin, was imaged...
