Objective: Serum alanine aminotransferase (ALT), which is an indicator of liver dysfunction, may increase during treatment in patients in the acute phase of stroke. However, the cause of the ALT elevation is unclear, as multiple medications are often being used. We investigated the relationship between medications used in acute ischemic stroke, including cerebral infarction and transient ischemic attack, and ALT elevation.

We have developed a novel method designated high-sensitivity allergy test (HiSAT) for determining allergy expression by measuring cell kinetics, using the chemotactic cells from non-allergic volunteers against a gradient field of cytokines released from immune cells when allergy develops. HiSAT requires a very small sample of 5 µL or less, and is applicable to three types of tests, depending on the situation in clinical practice: (i) diagnosis of the allergic expression, (ii) identification of the causative drug, and, in principle, (iii) pre-inspection.

Since conventional allergy testing is insufficient to accurately predict the occurrence of DIA or to determine the drugs causing it, the development of diagnostic and predictive tools for allergic reactions is important. We demonstrated a novel method, termed high-sensitive allergy test (HiSAT), for the rapid diagnosis of allergy (within 1 hr; with true-positive diagnosis rates of 89% and 9% for patients with and without allergy-like symptoms, respectively).

We investigated whether or not the introductions method affects the continuation rate of rotigotine patch.
Methods: The subjects were 188 PD patients who started using a rotigotine patch at the Department of Neurology, Fukuoka University Hospital.
Background: Photoimmunotherapy (PIT) employing antibody-photosensitizer conjugates is a promising treatment for cancer. However, the fixed antigen specificity severely limits the efficacy and the applicability. Here we describe a universal strategy for PIT of cancer by using a near-infrared (NIR) photosensitizer IRDye700DX-conjugated NeutrAvidin, designated as AvIR, together with various biotinylated antibodies (BioAbs) for cellular targeting.

On the other hand, skin disorders, mainly application site reaction, are characteristic problems associated with use of the patch. In this study, to clarify the influence of a topical agent used to prevent or treat rotigotine patch-induced skin disorder on continuation of the patch application, patients who started rotigotine patch application at our hospital were retrospectively surveyed.

Although lymphocytes with a chimeric antigen receptor (CAR) is a promising approach for overcoming this challenge in cancer immunotherapy, administration of modified T cells alone often demonstrates little efficacy in patients. Therefore, in order to enhance the antitumor activity of immune cells in the cancer microenvironment, we used lymphocytes expressing CAR in combination with a fusion protein of IL-2 that contained the single-chain fragmented antibody (scFv) specific for the carcinoembryonic antigen.

On the other hand, it was reported that adverse events, such as dermal disorder, frequently appeared after the start of rivastigmine administration. We retrospectively investigated medical records in 120 patients with moderate or mild AD in whom rivastigmine administration was started in the Department of Neurology, Fukuoka University Hospital between July 2011 and June 2014 (43 males, 77 females, mean age: 76.

Therefore, they are expected to reduce the patient burdens due to complications such as wearing-off and dysphagia. However, dosing is occasionally reduced or discontinued after application because of several reasons such as skin reactions or unsatisfactory efficacy.

We herein describe a highly effective and selective tumor-targeted PDT using a near-infrared (NIR) photosensitizer, IRDye700DX, conjugated to a human monoclonal antibody (Ab) specific for carcinoembryonic antigen (CEA). The antitumor effects of this Ab-assisted PDT, called photoimmunotherapy (PIT), were investigated in vitro and in vivo.

Fukuoka University Hospital has developed a problem-based learning (PBL) program concerning adverse drug reactions as long-term practical training to collect adverse event information, identify adverse effects, and acquire management skills. Students' level of satisfaction with the program was high (approximately 90%), and the mean self-evaluation score for the SBOs concerning adverse reaction was 4.

Use of ultrasound has the advantage of being noninvasive, with deep-penetration properties, and convenient because of the low or no sensitivity of sonosensitizers to light. In this study, SDT with a novel sonosensitizer (a porphyrin derivative) was evaluated in vitro and in vivo.

However, there are considerable problems with the clinical application of CAR, mostly due to its xenogeneic components, which could be immunogenic in humans. Moreover, while extensive studies on the CARs have been performed, the detailed molecular mechanisms underlying the activation of CAR-grafted T cells remain unclear.

There are three possible mechanisms of cancer therapy that employ anti-CEA antibody (Ab): Ab-dependent cell-mediated cytotoxicity (ADCC), complement-dependent cytotoxicity (CDC) or the prevention of CEA interaction with the extracellular matrix and/or intercellular adhesion molecules resulting in anoikis. In this study, the effect of C2-74, a human anti-CEA monoclonal Ab was evaluated.

Materials And Methods: First, normal rat brains were sonicated via a transducer placed on the dural surface to confirm safe acoustic conditions for normal rat brains.
The low-intensity ultrasound that is used in clinical diagnoses, such as abdomen echo inspection, is a non-invasive treatment, and penetrates deeper into the body than light. Recently, sonodynamic therapy (SDT), which uses low-intensity ultrasound together with a sonosensitizer, has been developed for cancer therapy in applying such properties of ultrasound. So far, most sonosensitizers that have been developed are sensitive to light as well as ultrasound, implying that the shortcomings of photosensitizers used during photodynamic therapy, such as skin sensitivity, still need to be overcome in SDT.

To prevent CMV infection and/or to prevent symptomatic CMV disease, immunoglobulin (Ig) G including hyperimmune CMV IgG are used alone or in combination with antiviral medications. The CMV IgG titer, however, has a wide range and frequently depends on the company supplying the Ig preparation even if the preparations come from the plasma pool of a national blood donation agency.

The possible involvement of claudin-1 (CL-1), one of the major tight junctional proteins (TJPs), was investigated in the tumorigenesis of CRC.
Patients And Methods: Adenocarcinoma tissue and paired normal mucosa specimens were resected from surgical specimens of CRC patients and analyzed to determine whether the expression of CL-1 correlated with the clinicopathological factors and to determine the role of CL-1 in the alteration of tight junctions during tumorigenesis.
IgA is able to trigger antibody-dependent cellular cytotoxicity (ADCC) by recruiting neutrophils expressing the Fc receptor for the CHalpha chain. We herein describe the preparation of a human recombinant anti-CEA IgA antibody to kill carcinoembryonic antigen (CEA)-expressing tumor cells via ADCC by neutrophils. A single chain Fv (scFv) gene was constructed using a cDNA library of a hybridoma clone that produces a human anti-CEA monoclonal IgG4 (C2-45).

Gene therapy has the potential to provide highly selective, curative cancer treatments without inducing systemic toxicity. Adenoviral vectors have been extensively used for cancer gene therapy because of their relatively high efficacy of gene transfer. However, gene transduction to cancer cells is limited by the necessity of using adenoviral type 5 vectors.
