Background And Aims: Guillain-Barré syndrome (GBS) is an acute, self-limited, immune-mediated peripheral neuropathy. Current treatments for GBS include intravenous immunoglobulin (IVIg) and plasma exchange, which may not sufficiently benefit severely affected patients. This study evaluated the efficacy and safety of eculizumab add-on therapy to IVIg (standard-of-care treatment) in patients with severe GBS.

The birefringence measurement by supercontinuum vector beam analysis provides kinematics of a singularity point on the space-variant retarder. We conducted numerical calculations and experiments for proof of principle.

The vector beam, which was generated by a pair of axially symmetric wave plates, leads to angular-variant polarization modulation to divide birefringence properties of a sample substrate into Fourier space. This strategy allows multispectral birefringence mapping from a single-shot image captured by a multispectral imaging detector.

Ideal therapy for lower urinary tract dysfunction in patients with spinal cord injury (SCI) should decrease detrusor overactivity, thereby promoting urine storage at low intravesical pressure and promoting efficient voiding at low pressure by decreasing detrusor-sphincter dyssynergia. Here we investigated blockade of various α-adrenoceptors to determine the subtype that was principally responsible for improving the voiding dysfunction. The effects of the intravenous α-blocker naftopidil, the α-blocker BMY 7378, and the α-blocker silodosin were evaluated using cystometrography and external urethral sphincter-electromyography (EMG) in decerebrated, unanesthetized female Sprague-Dawley rats with chronic SCI following transection at Th8.

He was referred to our department because his prostate-specific antigen (PSA) level was elevated (276 ng/ml). His Gleason score was 4+3, there was one bone metastasis in the left ileac bone, and multiple lung metastases were present.

However, recent studies suggest that undiscovered transcripts still exist in the human genome. Furthermore, a new technology, the DNA microarray, which can simultaneously characterize huge amounts of genome sequence data, has become a useful tool for analyzing genetic changes in various diseases.

A 77-year-old female who had gross hematuria and left lower abdominal pain was found to have a left renal tumor by computed tomography (CT) and was referred to our hospital. CT revealed a poorly enhanced mass in the left kidney and an enlarged paraaortic lymph node.

Urgency is the core symptom of the overactive bladder symptom complex, but the underlying mechanisms are not fully understood. Clinical findings have led to the assumption that bladder outlet obstruction (BOO) caused by benign prostatic enlargement (BPE) induces storage symptoms and detrusor overactivity. Presumably, BOO by BPE accounts for urgency; however, urgency is not always caused by BOO.

Melatonin improves nocturia. We hypothesized that melatonin could alleviate urinary frequency by suppressing the brain micturition center.

We reasoned that combination treatment of renal cell carcinoma (RCC) cells with COX-2 inhibitors and anticancer agents may result in synergistic apoptosis. We examined whether the selective COX-2 inhibitor JTE-522 synergizes with anticancer agents in cytotoxicity and apoptosis against RCC cells.

We investigated the usefulness of ultrasound-estimated bladder weight (UEBW) as a predictor of the need for surgery for benign prostatic hyperplasia (BPH).
Methods: A total of 97 consecutive male patients >50 years old with lower urinary tract symptoms (LUTS) were prospectively enrolled in this study.
RelA-associated inhibitor (RAI) was initially identified as a protein that interacts with the p65 subunit (RelA) of nuclear factor-kappaB. It was recently found to interact with the p53 tumor suppressor protein. RAI is a structural homolog of the p53-binding protein 2 and I kappaB family proteins, and is known to inhibit the DNA-binding activities of p65 and p53.

NK activity in ICR mouse splenocytes significantly increased from 4 h to 6 h after whole-body gamma-ray irradiation at 0.5 Gy, and thereafter decreased almost to the zero-time level by 24 h post-irradiation.

We determined whether U-50488 (trans-3,4-dichloro-N-methyl-N-[2-(1-pyrrolidinyl)-cyclohexyl]-benzeneacetamide), a kappa opioid receptor agonist, could decrease detrusor-sphincter dyssynergia (DSD) and, thus, improve voiding efficiency in conscious, spinal cord injured (SCI) rats.
Materials And Methods: Experiments were done in female Sprague-Dawley rats in which the spinal cord was completely transected at the T6-8 level 4 weeks prior to performing cystometry while conscious and held in a restraining cage.
A computer program system was developed to predict carbohydrate-binding sites on three-dimensional (3D) protein structures. The programs search for binding sites by referring to the empirical rules derived from the known 3D structures of carbohydrate-protein complexes. A total of 80 non-redundant carbohydrate-protein complex structures were selected from the Protein Data Bank for the empirical rule construction.
