Prevalence of depressive and anxiety disorders in an assisted reproductive technique clinic

BACKGROUND: Little is known about the prevalence of specific depressive and anxiety disorders in women before a new course of assisted reproductive technology treatment. Few studies have adopted the proper psychiatric diagnostic procedures. METHODS: All consecutive women visiting the assisted reproduction clinic of a university-affiliated medical centre, with the intention of starting a new assisted reproduction treatment course, were recruited. A psychiatrist made a diagnosis of psychiatric disorders using a structured interview, the Mini-International Neuropsychiatric Interview (MINI). RESULTS: Of a total of 112 participants, 40.2% had a psychiatric disorder. The most common diagnosis was generalized anxiety disorder (23.2%), followed by major depressive disorder (17.0%), and dysthymic disorder (9.8%). Participants with a psychiatric morbidity did not differ from those without in terms of age, education, income, or years of infertility. Women with a history of previous assisted reproduction treatment did not differ from those without in depression or anxiety. CONCLUSIONS: Depressive and anxiety disorders were highly prevalent among women who visited an assisted reproduction clinic for a new course of the treatment. Demographic features and a history of previous assisted reproduction treatment were not risk factors for these psychiatric morbidities in the assisted reproduction clinic.     

Development of an antigen-capture enzyme-linked immunosorbent assay using monoclonal antibodies for detecting H6 avian influenza viruses

The H6 subtype of avian influenza virus (AIV) infection occurs frequently in wild and domestic birds. AIV antigen detection is preferred for controlling AIV as birds are infected before they produce antibodies. The purpose of this study was to develop an early diagnostic method for AIV detection. Six monoclonal antibodies (mAbs) developed from a field H6N1 AIV strain were tested for their ability to bind to viruses. The two that showed the greatest binding ability to AIVs were used for antigen detection. An antigen-capture enzyme-linked immunosorbent assay (ELISA) to detect H6 AIVs was developed using these mAbs. One mAb was coated onto an ELISA plate as the capture antibody. The other mAb was used as the detector antibody after labeling with horseradish peroxidase. The antigen-capture ELISA detected H6N1 AIVs but not H5 AIVs, human H1N1, H3N2 influenza or other viruses. This antigen-capture ELISA could be used to specifically detect H6N1 AIV.     

Peroxisome proliferator-activated receptor delta agonists attenuated the C-reactive protein-induced pro-inflammation in cardiomyocytes and H9c2 cardiomyoblasts

C-reactive protein (CRP) has emerged as a new marker for cardiovascular diseases. Activation of peroxisome proliferator-activated receptor δ (PPARδ) plays beneficial roles in cardiac disorders. However, the relationship between CRP and PPARδ in cardiac cells remains unclear. This study focused on the underlying molecular mechanisms of CRP and PPARδagonists. Cardiomyocytes and cardiomyoblast cell line (H9c2) were used in different groups: Untreated; 15 μg/ml CRP with or without 1 μM PPARδ agonists (L-165041). CRP increased PPARδ and interleukin-6 expression in cardiomyocytes and H9c2 cardiomyoblasts. NF-κB inducing kinase (NIK) and NF-κB pathway also activated by CRP stimulation. These changes could be inhibited by L-165041 through p38MAPK and c-JNK pathways. However, transfection with siRNA of CD32 CRP receptor did not decrease CRP signaling or reverse the effects of L-165041 in CRP-treated cardiomyocytes and H9c2. Pretreatment with L-165041 attenuated apoptosis induced by hypoxia with or without CRP in H9c2 cardiomyoblasts. CRP up-regulated PPARδ expression in cardiomyocytes and H9c2. L-165041 attenuated CRP-induced pro-inflammatory signaling through p38MAPK and c-JNK in H9c2 cardiomyoblasts. However, PPARδ activation attenuated CRP-induced NF-κB pathway may be independent of CD32. These results may provide new evidence of PPARδ beneficial effects for inflammatory cardiomyopathy.     

Implementation of digital stereo imaging for analysis of metaphyses and joints in skeletal collections

The surface structure of the growing portion of bones, called the metaphysis, contains clues about the locomotor characteristics of various species. Present methods of capturing this anthropologically interesting surface are time-consuming and subject to human error. The research implements a digital stereo imaging technique for bone metaphyses and joints in skeletal collections. The corresponding points in two images collected from different angles are determined using an areabased correlation matching method. The depths of matched points are computed from the difference in location of the points in the two images. The paper presents a practical implementation of computer vision for anthropology using an 80286-based personal computer, a camera and a video digitiser. The stereo matching algorithm, a practical implementation of classical stereo imaging methods, takes less than 1 min and produces reasonable representations of mammal bones. The accuracy of the depth measurements ranged from 0·7 to 12 per cent for 45–150 cm object-camera distances. False matches occurred in approximately 6 per cent of the total matched points.     

The Correlation Between CVP and SVV and Intraoperative Minimal Blood Loss in Living Donor Hepatectomy

Background

Blood loss during liver surgery is found to be correlated with central venous pressure (CVP). The aim of the current retrospective study is to find out the cutoff value of CVP and stroke volume variation (SVV), which may increase the risk of having intraoperative blood loss of more than 100 mL during living liver donor hepatectomies.

MR imaging of facial nerve enhancement in Bell palsy or after temporal bone surgery

The authors evaluated magnetic resonance (MR) images obtained with intravenously administered gadolinium in ten patients who had facial paralysis and no facial nerve tumor. In patients with either Bell palsy (four patients) or facial paralysis after temporal bone surgery (six patients), intratemporal facial nerve enhancement was seen. Facial nerve enhancement on MR images proved to be a nonspecific finding.     

Anesthesia Management and Fluid Therapy in Right and Left Lobe Living Donor Hepatectomy

Objective

Right lobe living donor hepatectomy poses a greater risk for the donor in relation to blood loss. The aims of this study were to compare anesthetic and intraoperative fluid management in right and left lateral segment living donor hepatectomy.
