Hereditary Hemorrhagic Telangiectasia with Recurrent Epistaxis, Telangiectasia, Hepatic Arteriovenous Malformation, and a Poorly Developed Middle Cerebral Artery in a Patient with a Novel Mutation in the ACVRL1 Gene.

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal-dominant vascular disorder characterized by intractable epistaxis, mucocutaneous telangiectasias, and arteriovenous malformations (AVMs) in multiple organs, including the lungs, liver, gastrointestinal tract, brain, and spinal cord. We herein report a 50-year-old Japanese man with HHT who experienced recurrent epistaxis, telangiectasia in the cornea, apex of the tongue and fingers; hepatic AVM; and a poorly developed main arterial trunk in the right middle cerebral artery. A genetic analysis revealed a novel heterozygous mutation in the activin A receptor-like type 1 gene, with a frameshift mutation in NM_000020.

ZFAND3 Overexpression in the Mouse Liver Improves Glucose Tolerance and Hepatic Insulin Resistance.

Genome-wide association studies have identified more than 300 loci associated with type 2 diabetes mellitus; however, the mechanisms underlying their role in type 2 diabetes mellitus susceptibility remain largely unknown. Zinc finger AN1-type domain 3 (ZFAND3), known as testis-expressed sequence 27, is a type 2 diabetes mellitus-susceptibility gene. Limited information is available regarding the physiological role of ZFAND3 .

Two Patients with Large Aneurysms in Whom Coil Embolization with Overlapping LVIS Stents Was Performed.

Objective: We report two patients with unruptured large aneurysms treated by overlapping stent-assisted coil embolization using low-profile visualized intraluminal support (LVIS) stents.

Case Presentation: Case 1: An 80-year-old woman presented with abducens nerve palsy due to an internal carotid artery aneurysm. Case 2: A 75-year-old man presented with a partially thrombosed fusiform aneurysm in the vertebral artery (VA).

[A Case of Brain, Lung, and Adrenal Metastasis from Colorectal Cancer Controlled by Loco-Regional Surgery].

A 64-year-old man presented with the chief complaint of weakness in the left half of his body. He fell down on the road while riding a bicycle and was transported to the emergency room. A contrast-enhanced brain MRI revealed a 28mm ringshaped mass in the right frontal lobe.

A novel application of infrared imaging for the diagnosis of death by fire.

This paper demonstrates a novel and simple technique for the diagnosis of death by fire using a digital infrared (IR) camera system. At autopsy, the inhalation of soot by a fire victim is a definite indicator proving a vital reaction during the fire. However, there can be difficulties in confirming the presence of soot because of the relative lack of soot or the similarity in color between soot and surrounding tissues.

The genome folding mechanism in yeast.

The structure of the nucleosome has been solved at atomic resolution, and the genome-wide nucleosome positions have been clarified for the budding yeast Saccharomyces cerevisiae. However, the genome-wide three-dimensional arrangement of nucleosomal arrays in the nucleus remains unclear. Several studies simulated overall interphase chromosome architectures by introducing the putative persistence length of the controversial 30-nm chromatin fibres into the modelling and using data-fitting approaches.

Investigation of proteomic profiles of lamina of Ecklonia kurome (Laminariales): homology-based cross-species protein identification and analysis of the post-translational processing of vanadium-dependent bromoperoxidases using MALDI-TOF/TOF.

Proteomic profiles of the lamina of Ecklonia kurome Okamura, one of the Japanese dominant laminarialean kelps, were investigated by two-dimensional electrophoresis (2-DE) and MALDI-TOF/TOF. Due to the absence of E. kurome DNA or protein databases, homology-based cross-species protein identification was performed using a combination of three database-searching algorithms, Mascot peptide mass fingerprinting, Mascot MS/MS ion search, and mass spectrometry-based BLAST.

Regions of unusually high flexibility occur frequently in human genomic DNA.

Remarkable progress has been made in genome science during the past decade, but understanding of genomes of eukaryotes is far from complete. We have created DNA flexibility maps of the human, mouse, fruit fly, and nematode chromosomes. The maps revealed that all of these chromosomes have markedly flexible DNA regions (We named them SPIKEs).

Nuclear localization of reporter genes activated by curved DNA.

Curved DNA structures with a left-handed superhelical conformation can activate eukaryotic transcription. Mechanistically, these structures favor binding to histone cores and can function as a docking site for sliding nucleosomes. Thus, promoters with this kind of curved DNA can adopt a more open structure, facilitating transcription initiation.

Berberine-induced activation of 5'-adenosine monophosphate-activated protein kinase and glucose transport in rat skeletal muscles.

Berberine (BBR) is the main alkaloid of Coptis chinensis, which has been used as a folk medicine to treat diabetes mellitus in Asian countries. We explored the possibility that 5'-adenosine monophosphate-activated protein kinase (AMPK) is involved in metabolic enhancement by BBR in skeletal muscle, the important tissue for glucose metabolism. Isolated rat epitrochlearis and soleus muscles were incubated in a buffer containing BBR, and activation of AMPK and related events were examined.

Cotransplantation of mouse embryonic stem cells and bone marrow stromal cells following spinal cord injury suppresses tumor development.

Embryonic stem (ES) cells are a potential source for treatment of spinal cord injury (SCI). Although one of the main problems of ES cell-based cell therapy is tumor formation, there is no ideal method to suppress tumor development. In this study, we examined whether transplantation with bone marrow stromal cells (BMSCs) prevented tumor formation in SCI model mice that received ES cell-derived grafts containing both undifferentiated ES cells and neural stem cells.

Protein extraction for 2-DE from the lamina of Ecklonia kurome (laminariales): recalcitrant tissue containing high levels of viscous polysaccharides.

Extraction of proteins from the tissues of laminarialean algae, i.e. kelp, is difficult due to high levels of nonprotein interfering compounds, mainly viscous polysaccharides.

Complications and long-term follow-up results in titanium mesh cage reconstruction after cervical corpectomy.

Objective: The incidence of the complications and long-term outcome with a minimum 2-year follow-up of anterior cervical reconstruction using titanium mesh cage is evaluated. Relevant literature was also reviewed to discuss the potential risk factors of the complications of this procedure.

Methods: From 1999 to 2003, 26 patients with cervical spine disorders, (12 patients with OPLL, 7 with cervical spondylosis, 3 with vertebral tumors, 2 with osteomyelitis, and 2 with traumatic lesions) were operated on by this procedure.

Transplantation of embryonic stem cell-derived neural stem cells for spinal cord injury in adult mice.

Aims: To investigate the efficacy of embryonic stem cell-derived neural stem cells (NSCs) for spinal cord injury (SCI) in mice and whether a combination treatment with thyroid hormone provides a more effective ES cell-based therapy.

Methods: Nestin-positive NSCs were induced from undifferentiated mouse ES cells by a step-by-step culture and used as grafts. Thirty-six mice were subjected to an SCI at Th10 and divided into three groups of 12.

Intraventricular transplantation of embryonic stem cell-derived neural stem cells in intracerebral hemorrhage rats.

In the present study, we attempted to explore cell transplantation therapy for intracerebral hemorrhage (ICH) using embryonic stem (ES) cells. Collagenase-induced ICH rats were used as model animals. Mouse ES cells were differentiated into nestin-positive neural stem cells in vitro by alltrans retinoic acid (ATRA).

Selective removal of circulating immune complexes from patient plasma.

The principle of a patient-specific immunoadsorber (PsIA) is demonstrated. Studies with model systems (HSA/anti-HSA) on immobilization, stability, and leakage form the basis for the presented fast-performance liquid chromatography (FPLC) and batch experiments, which were conducted using two different protein A adsorbers and autologous and heterologous PsIA systems. Experiments to determine the binding capacity of protein A adsorbers and PsIAs are described.
