This phase III study assessed the efficacy and safety of sacubitril/valsartan compared with those of olmesartan in Japanese patients with essential hypertension. Patients (n = 1161, aged ≥20 years) with mild to moderate hypertension (mean sitting systolic blood pressure [msSBP] ≥150 to <180 mmHg) were randomized to receive sacubitril/valsartan 200 mg (n = 387), sacubitril/valsartan 400 mg (n = 385), or olmesartan 20 mg (n = 389) once daily for 8 weeks. The primary assessment was a reduction in msSBP from baseline with sacubitril/valsartan 200 mg vs.

The molecular basis of interleukin (IL)-17A in driving psoriasis pathogenesis is not fully elucidated yet. To investigate the underlying mechanisms and biomarkers associated with IL-17A and the role in psoriasis pathogenesis, over 30 serum proteins were evaluated in a study assessing the effectiveness and safety of secukinumab, where treatment was directly switched from cyclosporin A to secukinumab. Serum β-defensin 2 (BD-2) levels rapidly and robustly reduced following secukinumab treatment.

Secukinumab, a fully human monoclonal antibody neutralizing interleukin-17A, has been shown to have significant efficacy in the treatment of moderate to severe psoriasis. Long-term (3-year) efficacy and safety of secukinumab in Japanese patients with moderate to severe psoriasis were evaluated in an extension study of a large phase 3 global study (SCULPTURE). In the core study, 52 Japanese patients with 75% improvement of Psoriasis Area and Severity Index (PASI-75) response at week 12 were re-randomized to a fixed interval (FI; every 4 weeks) schedule and retreatment as needed (RAN), in which patients received placebo until start of relapse, at which time secukinumab was reinitiated.

There are limited data on the safety and efficacy of switching to secukinumab from cyclosporine A (CyA) in patients with psoriasis. The purpose of the present study was to assess the efficacy and safety of secukinumab for 16 weeks after direct switching from CyA in patients with moderate-to-severe psoriasis. In this multicenter, open-label, phase IV study, 34 patients with moderate-to-severe psoriasis and inadequate response to CyA received secukinumab 300 mg s.

To explore the effects of various antihypertensive regimes on microalbuminuria, an angiotensin II receptor blocker (ARB), valsartan, was substituted for or added to treatment with a calcium channel blocker (CCB). After a 6-month CCB baseline period, 28 Japanese hypertensive patients with incipient diabetic nephropathy (defined as a urinary albumin excretion [UAE] of 30-300 mg/g creatinine), were assigned to two groups according to their blood pressure (BP) levels: in patients with a BP of more than 130/85 mmHg (n=17), valsartan was added to the CCB (Group A), while in patients with a BP <130/85 mmHg, valsartan alone was given (Group B: n=11) for 12 months. UAE was determined before and at 3, 6 and 12 months after the initiation of ARB.

The process of parental acceptance of a child's disability is complex and involves a myriad of factors, including the nature of the child's disability, factors related to the parents and societal factors. Despite the type of disability and the severity of that disability often being the most significant factors related to the process of acceptance, the majority of previous studies have combined multiple disabilities into a single category. For example, the point at which parent and child begin to live together with a disability marks a "beginning.

This study used a literature review to examine the process of parental acceptance regarding disability in a child. Our results identify two main theoretical concepts, stages of grief and chronic sorrow, which describe the emotional responses that parents express following the diagnosis of a child's disability. Stages of grief involve a long-term process through which parents struggle to accept their child's condition, eventually leading to acceptance of their child's disability.

UDP-N-Acetylglucosamine: alpha-3-D-mannoside beta-1,2-N-acetylglucosaminyltransferase I (GnT-I) is an essential enzyme in the conversion of high mannose type oligosaccharide to the hybrid or complex type. The full length of the rat GnT-I gene was expressed in the filamentous fungus Aspergillus oryzae. A microsomal preparation from a recombinant fungus (strain NG) showed GnT-I activity that transferred N-acetylglucosamine residue to acceptor heptaose, Man(5)GlcNAc(2).

1,2-alpha-Mannosidase catalyzes the specific cleavage of 1,2-alpha-mannose residues from protein-linked N-glycan. In this study, a novel DNA sequence homologous to the authentic 1,2-alpha-mannosidase was cloned from a cDNA library prepared from solid-state cultured Aspergillus oryzae. The fmanIB cDNA consisted of 1530 nucleotides and encoded a protein of 510 amino acids in which all consensus motifs of the class I alpha-mannosidase were conserved.

To understand the current Japanese hair mercury levels, we planned a survey of hair mercury among the general populations of different regions in Japan. The present paper, as the first report of the survey, summarized the results obtained in five districts, Minamata, Kumamoto, Tottori, Wakayama and Chiba. Hair samples were collected at beauty salons, barbershops and primary schools in each district with questionnaires on age, sex, amount and species of fish usually consumed, hair-dyed and artificial hair waving "permanent wave.
