Elbasvir (EBR)/grazoprevir (GZR) may be coadministered with immunosuppressant drugs in posttransplant people who are infected with hepatitis C virus. The aim of the present study was to assess the safety and pharmacokinetic interactions between EBR and GZR and single doses of cyclosporine, tacrolimus, mycophenolate mofetil (MMF), and prednisone. This was a 4-part, open-label study in 58 healthy volunteers. Participants received single doses of cyclosporine 400 mg, tacrolimus 2 mg, MMF 1 g, or prednisone 40 mg alone or in the presence of once-daily EBR 50 mg/GZR 200 mg...

Systemic sclerosis (SSc) is an intractable disease that causes fibrosis in all organs. Approximately 40% of patients with SSc have some degree of interstitial lung disease (ILD). One third of patients with SSc and ILD, approximately 15% of all patients, have pulmonary lesions, which slowly progress to respiratory failure resistant to corticosteroid and other treatments. A randomized controlled trial conducted in the United States indicated that one year of treatment with oral cyclophosphamide in patients with SSc-ILD had a significant but modest beneficial effect on lung function, dyspnea, thickening of the skin, and health-related quality of life...

Lupus pneumonitis carries high mortality and is a rare manifestation of systemic lupus erythematosus (SLE). However, it is difficult to diagnose and is often mistaken as pneumonia, alveolar haemorrhage, or organizing pneumonia. Previous studies demonstrated that serum anti-Ro antibodies are elevated more frequently in SLE patients with pneumonitis than in those without. We report a 21-year-old female who was newly diagnosed as having SLE with nephritis and who suddenly developed right lung opacity and rapidly progressed to severe hypoxaemia despite the use of broad-spectrum antibiotics...

Lymphocytic hypophysitis (LHP) is a relatively rare disease characterised by lymphocytic infiltration of the pituitary gland, resulting in pituitary dysfunction. LHP is generally responsive to corticosteroid therapy, but cases with recurrence require clinicians to select second-line therapy. We report here the case of a 58-year-old patient with LHP who developed panhypopituitarism and bitemporal hemianopia. He responded to prednisolone 40 mg/day but relapsed during tapering. The prednisolone dose was increased again and mycophenolate mofetil (MMF) was added...

BACKGROUND: CD4+CD25Hi FoxP3+ T (Treg) cells are a small subset of CD4+ T cells that have been shown to exhibit immunoregulatory function. Although the absolute number of Treg cells in peripheral blood lymphocytes (PBL) is very small, they play an important role in suppressing immune reactivity. Several studies have demonstrated that the number of Treg cells, rather than their intrinsic suppressive capacity, may contribute to determining the long-term fate of transplanted grafts. In this study, we analyzed Treg cells in PBL of long-term baboon recipients who have received genetically modified cardiac xenografts from pig donors...

A dual-wavelength fiber ring laser based on multimode fiber-polarization maintaining fiber Bragg grating-multimode fiber (MMF-PMFBG-MMF) filter for simultaneously axial strain, temperature and refractive index (RI) sensing is proposed and experimentally demonstrated. In the ring laser, stable dual-wavelength lasing is determined by the MMF-PMFBG-MMF filter with two polarization states. The fiber birefringence affected by axial strain is far less than the effect of the temperature. Through monitoring the variations of each wavelength shift and output power, the simultaneous measurement for the axial strain, temperature and RI is realized...

Jian Zhang, Chong Ding, Xiaofeng Meng, Peng Shang
Nitric oxide (NO) is involved in osteoclast differentiation. Our previous studies showed that static magnetic fields (SMFs) could affect osteoclast differentiation. The inhibitory effects of 16 T of high SMF (HiMF) on osteoclast differentiation was correlated with increased production of NO. We raised the hypothesis that NO mediated the regulatory role of SMFs on osteoclast formation. In this study, 500 nT of hypomagnetic field (HyMF), 0.2 T of moderate SMF (MMF) and 16 T of high SMF (HiMF) were utilized as SMF treatment...

REVIEW
Chi Chiu Mok
The calcineurin inhibitors (CNIs) belong to a group of immunosuppressive agents that block T-cell activation through the suppression of the calcium/calcimodulin-dependent phosphatase calcineurin. Agents such as cyclosporine A (CSA) and tacrolimus (TAC) have long been used in patients with systemic lupus erythematosus (SLE). TAC is preferred to CSA in SLE because of the lower frequency of cosmetic, hypertensive and dyslipidemic adverse effects. Recent randomised controlled trials have demonstrated noninferiority of TAC to mycophenolate mofetil (MMF) or cyclophosphamide (CYC) for induction therapy of lupus nephritis...

The inferior frontal and superior temporal areas in the left hemisphere are crucial for human language processing. In the present study, we investigated the magnetic mismatch field (MMF) evoked by voice stimuli in 3- to 5-year-old typically developing (TD) children and children with autism spectrum disorder (ASD) using child-customized magnetoencephalography (MEG). The children with ASD exhibited significantly decreased activation in the left superior temporal gyrus compared with the TD children for the MMF amplitude...

Optical clearing is emerging as a popular approach particularly for studies in neuroscience. However the use of corrosive clearing solutions typically requires sophisticated objectives or extreme care with optical components chosen for single- or multi-photon imaging. In contrast to the use of complex, custom-made microscope objectives, we show that the use of a corrected multimode fibre (MMF) offers a route that is resistant to corrosion, can be used in clearing media, is not constrained by the refractive index of the immersion medium and offers flexible working distances...

REVIEW

Fumaric acid ester-based drugs are used for the treatment of psoriasis and multiple sclerosis. All licensed fumaric acid ester drugs contain dimethylfumarate (DMF) as the main active component. Due to the expanding use of oral DMF there is growing scientific interest in determining its as-yet-unknown mechanism of action. However, the pharmacology and chemistry of DMF are often not fully considered in the design and interpretation of experiments; namely, that while DMF is plasma-membrane permeable and has strong effects on many cell types in vitro, it is rapidly metabolized into membrane-impermeable monomethylfumarate (MMF) in vivo...

BACKGROUND: Henoch-Schönlein purpura (HSP) is the most common vasculitis in childhood and traditionally considered as a self-limiting disease. However, renal involvement can unfavorably determine long-term prognosis. The reported regimens to treat HSP nephritis (HSPN) are diverse, indicating that the most effective treatment remains controversial. METHODS: This retrospective, single-center study involved 18 patients presenting with HSPN and nephrotic-range proteinuria...

Effective extraction is a key step in the determination of sulfonylurea herbicides (SUHs) in complicated samples. According to the chemical properties of SUHs, a new monolithic adsorbent utilizing acrylamidophenylboronic acid and vinylimidazole as mixed functional monomers was synthesized. The new adsorbent was employed as the extraction phase of multiple monolithic fiber solid-phase microextraction (MMF-SPME) of SUHs, and the extracted SUHs were determined by high-performance liquid chromatography with diode array detection (HPLC-DAD)...

BACKGROUND: A population pharmacokinetic (PK) protein-binding model was developed to (1) predict free mycophenolic acid (fMPA) based on total MPA (tMPA) concentrations in renal transplant patients, to establish the therapeutic range of fMPA through pharmacokinetic-pharmacodynamic studies; and (2) provide a guideline for dosing mycophenolate mofetil (MMF). METHODS: Full PK profiles of 56 patients (from five different occasions) during the first year after transplantation who were treated with oral MMF and cyclosporine, or macrolides (either tacrolimus or sirolimus), were analysed...

There is evidence that suboptimal complementary feeding contributes to poor child growth. However, little is known about time trends and determinants of complementary feeding in Nepal, where the prevalence of child undernutrition remains unacceptably high. The objective of the study was to examine the trends and predictors of suboptimal complementary feeding in Nepali children aged 6-23 months using nationally representative data collected from 2001 to 2014. Data from the 2001, 2006, and 2011 Nepal Demographic and Health Surveys and the 2014 Multiple Indicator Cluster Survey were used to estimate the prevalence, trends and predictors of four WHO-UNICEF complementary feeding indicators: timely introduction of complementary foods (INTRO), minimum meal frequency (MMF), minimum dietary diversity (MDD), and minimum acceptable diet (MAD)...

Clinical limitations following closed reduction of an intracapsular condylar fracture include a decrease in maximum mouth opening, reduced range of mandibular movements such as protrusion/lateral excursion, and reduced occlusal stability. Anteromedial and inferior displacement of the medial condyle fragment by traction of the lateral pterygoid muscle can induce bone overgrowth due to distraction osteogenesis between the medial and lateral condylar fragments, causing structural changes in the condyle. In addition, when conventional maxillomandibular fixation (MMF) is performed, persistent interdental contact sustains masticatory muscle hyperactivity, leading to a decreased vertical dimension and premature contact of the posterior teeth...

With the continuous use of immunosuppressive agents routinely, the long-term survival rate of organ transplant recipients has been incessantly improved. However, the risk of de novo malignancies is also increasing, which has become the second cause of death after organ transplantation. De novo gastrointestinal malignancies are common after liver or kidney transplantation, mostly with advanced stage when diagnosed and poor prognosis. There is a significant trend in the development of de novo malignancies in transplant recipients, which is probably related to factors, including direct or indirect effects of immunosuppressive agents, precancerosis and survival time of transplanted grafts and recipients...
