Successful carotid stenting of a carotid arterial dissection after straightening the tortuosity using an inflated balloon guiding catheter and the delivery wire of an anchored stent retriever.

The authors present a patient with carotid dissection in a tortuous arterial segment who successfully underwent carotid artery stenting (CAS) by straightening the tortuosity using an inflated balloon guiding catheter (BGC) and a stent retriever (SR). A 56-year-old man was transferred to our institute with right hemiparesis and a National Institutes of Health Stroke Scale score of 9. Magnetic resonance imaging showed left internal carotid artery (ICA) occlusion and ischemic change in the parietal lobe.

Using a low-metal-density stent for thrombectomy-resistant vertebrobasilar occlusion due to thrombus migration from a thrombosed vertebral artery aneurysm: illustrative case.

Background: Thrombosed intracranial aneurysms can lead to large vessel occlusion as a result of spontaneous thrombosis. Although mechanical thrombectomy is likely effective, recurrent thromboembolism can occur if the thrombotic source remains untreated. The authors describe a case of recurrent vertebrobasilar artery occlusion due to thrombus migration from a large thrombosed vertebral artery (VA) aneurysm that was successfully treated with mechanical thrombectomy followed by stenting.

Impact of germline HLA genotypes on clinical outcomes in patients with urothelial cancer treated with pembrolizumab.

Human leukocyte antigen class I (HLA-I) genotypes are suggested to influence the cancer response to checkpoint blockade immunotherapy. This study assessed the impact of germline HLA genotypes on clinical outcomes in patients with chemoresistant advanced urothelial cancer (UC) treated with pembrolizumab. Zygosity, supertypes, evolutionary divergency, and specific alleles of germline HLA-I and -II were evaluated using the Luminex technique in 108 patients with chemoresistant metastatic or locally advanced UC treated with pembrolizumab.

Expression of cell adhesion molecule, Gicerin/CD146 during the formation of heart and in the cardiac hypertrophy.

Gicerin/CD146 is a cell adhesion molecule which belongs to the immunoglobulin (Ig) superfamily. We have reported the existence of gicerin/CD146 in the nervous system, heart, lung and smooth muscles of blood vessels. In this study, we make a cardiac hypertrophy model rat by constricting the rat aorta (AAC, ascending aortic constriction) and examined the effect on the expression of gicerin/CD146 in the heart.

Deep Decompression of the Lateral Femoral Cutaneous Nerve Under Local Anesthesia.

Objective: Meralgia paresthetica is a mononeuropathy of the lateral femoral cutaneous nerve (LFCN) caused by compression around the inguinal ligament. We report a surgical alternative for the treatment of meralgia paresthetica under local anesthesia and its outcomes.

Methods: We operated on 12 patients with unilateral meralgia paresthetica whose age at surgery ranged from 62 to 75 years.

Superselective Drug Delivery Using Doxorubicin-Encapsulated Liposomes and Ultrasound in a Mouse Model of Lung Metastasis Activation.

Conventional treatment of lymph node metastasis involves dissection of the tumor and regional lymph nodes, but this may cause activation of latent metastatic tumor cells. However, there are few reports on animal models regarding the activation of latent metastatic tumor cells and effective methods of treating activated tumor cells. Here, we report the use of a superselective drug delivery system in a mouse model of lung metastasis in which activated tumor cells are treated with doxorubicin-encapsulated liposomes (DOX-LP) and ultrasound.

Swallowing disorder following salvage total pharyngo-laryngo-esophagectomy with free jejunum reconstruction.

For recurrent cases or residual cases following concomitant chemo-radiation therapy (CCRT), salvage surgery is a frequently used treatment options. A swallowing disorder is one of the major complications of CCRT. The purpose of the present study was to evaluate the effect of CCRT on swallowing function in patients who underwent salvage total pharyngo-laryngo-esophagectomy (TPLE), and to evaluate the importance of pharyngeal constriction in patients who underwent TPLE.

Cardiac overexpression of perilipin 2 induces dynamic steatosis: prevention by hormone-sensitive lipase.

Cardiac intracellular lipid accumulation (steatosis) is a pathophysiological phenomenon observed in starvation and diabetes mellitus. Perilipin 2 (PLIN2) is a lipid droplet (LD)-associated protein expressed in nonadipose tissues, including the heart. To explore the pathophysiological function of myocardial PLIN2, we generated transgenic (Tg) mice by cardiac-specific overexpression of PLIN2.

Variability of treatment planning of seed implantation: A Japanese multicenter simulation study.

Purpose: This multicenter study was conducted to evaluate the current variability of treatment planning of seed implantation in Japanese centers and the feasibility of two virtual trials.

Methods And Materials: Two types of contour data were sent to 12 radiation oncologists with a request letter that asked them to make treatment plans on the data in the same manner as in their own practice. Five of the 12 radiation oncologists were asked to participate in the two virtual trials in which the D90 (dose to the hottest 90% of prostate volume) was 1) required to be set at just 180 Gy and 2) increased as much as possible without violating other limitations.

Assessment of vascular response after drug-eluting stents implantation in patients with diabetes mellitus: an optical coherence tomography sub-study of the J-DESsERT.

Even in the drug-eluting stent era, diabetes mellitus (DM) patients have high incidences of restenosis and repeat revascularization after percutaneous coronary intervention. The aim of this study was to compare vascular response after stent implantation between sirolimus-eluting stent (SES) and paclitaxel-eluting stent (PES) by using optical coherence tomography (OCT) in DM patients as well as in non-DM patients. In the Japan-Drug Eluting Stents Evaluation; a Randomized Trial (J-DESsERT), the OCT sub-study enrolled 75 patients who underwent 8 months follow-up imaging after SES or PES implantation.

Prevalence and characteristics of TCFA and degree of coronary artery stenosis: an OCT, IVUS, and angiographic study.

Background: The relationship between features of vulnerable plaque and angiographic coronary stenosis is unknown.

Objectives: The purpose of this study was to systematically investigate the absolute number, relative prevalence, and characteristics of thin-cap fibroatheroma (TCFA) at different degrees of stenosis using optical coherence tomography (OCT), intravascular ultrasound, and coronary angiography.

Methods: We identified 643 plaques from 255 subjects who underwent OCT imaging in all 3 coronary arteries.

Fibrosing cholestatic hepatitis developing within one month after living donor liver transplantation for chronic hepatitis C-related cirrhosis: a case report.

Fibrosing cholestatic hepatitis (FCH) is a life-threatening consequence of hepatitis C virus (HCV) infection occurring in a small minority of liver transplantation (LT) recipients. We herein report a case of early-onset FCH after living donor LT in a 47-year-old woman with HCV-related cirrhosis. The patient underwent balloon-occluded retrograde transvenous obliteration of a splenorenal shunt to treat an impaired portal flow on the sixth postoperative day (POD 6) and a bypass operation for hepatic artery thrombosis on POD 12.

Methamphetamine induces endoplasmic reticulum stress related gene CHOP/Gadd153/ddit3 in dopaminergic cells.

We examined the toxicity of methamphetamine and dopamine in CATH.a cells, which were derived from mouse dopamine-producing neural cells in the central nervous system. Use of the quantitative real-time polymerase chain reaction revealed that transcripts of the endoplasmic reticulum stress related gene (CHOP/Gadd153/ddit3) were considerably induced at 24-48 h after methamphetamine administration (but only under apoptotic conditions), whereas dopamine slightly induced CHOP/Gadd153/ddit3 transcripts at an early stage.

Inflammatory cytokines decrease the expression of nicotinic acetylcholine receptor during the cell maturation.

It is known that the nervous system significantly attenuates systemic inflammatory responses through the parasympathetic nervous system. Furthermore, it has been reported that the alpha 7 subunit of a nicotinic acetylcholine receptor is required for a cholinergic inhibition against cytokine synthesis in a macrophage. As antigen-presenting cells (APCs) play a central role in the generation of primary T cell responses and the maintenance of immunity, in this study, we investigated the expression level of nicotinic receptors of a p53-deficient APC cell line (JawsII) derived from a mouse bone marrow.

Gicerin/CD146 is involved in neurite extension of NGF-treated PC12 cells.

Gicerin/CD146 is a cell adhesion molecule, which belongs to the immunoglobulin (Ig) superfamily. We have reported that it has a homophilic binding activity, which participates in the neurite extension from embryonic neurons. To elucidate how gicerin is involved in the neurite extension mechanism, we employed PC12 cells, which expresses gicerin/CD146.

[Hepatic blood flow decreases during laparoscopic cholecystectomy].

Changes of median hepatic venous blood flow (MHVBF) and left portal venous blood flow (Lt. PVBF) were measured continuously in 31 patients undergoing elective laparoscopic cholecystectomy (LC) by using transesophageal echocardiography (TEE). The patients were anesthetized with inhalation and epidural anesthesia.

[Genomic analysis of Japanese patients with adult-type metachromatic leukodystrophy].

We performed the genomic analysis of arylsulfatase A (ASA) gene in five Japanese patients with adult-type metachromatic leukodystrophy (MLD) including two sibling cases. Sequencing of amino acid coding region of ASA gene of proband case of family A disclosed 426Pro (CCG)-->Leu (CTG) mutation, which was reported to be frequently found in Caucasian patients with late-onset MLD. We developed mismatch primer PCR/RFLP method for detection of this mutation.

[Two siblings with metachromatic leukodystrophy of adult and juvenile onset].

We reported two siblings with metachromatic leukodystrophy of adult and juvenile onset. Patient 1, a 24-year-old female had been unremarkable until 23 years, when she began to develop loss of spontaneity, bradykinesia and gait disturbance. Nine months later, she became unable to walk and mentally deteriorated.

[A study of chest X-ray classification of farmer's lung--correlation between X-ray pattern and background factors].

Patients with farmer's lung were classified into five groups according to their chest X-ray pattern, and the background of each group was studied with respect to stage, severity, and prognosis. Type I group, which has fine nodular shadows on chest X-ray, showed a significantly high percentage of lymphocytes in BAL cells (p less than 0.01).
