Mycophenolate mofetil (MMF) is used extensively for the induction therapy of lupus nephritis (LN) and has even outpaced intravenous (i.v.) cyclophosphamide (CyP) as the initial choice of therapy. There are no studies comparing the response of MMF with standard dose i.v. CyP in Indian patients with LN. We conducted a 24-week prospective, randomized, open-label trial comparing oral MMF with monthly i.v. CyP as induction therapy for active biopsy proven Class III and IV LN. The primary end-point was response to treatment at 24 weeks, and the secondary end-points were complete remission, Systemic Lupus Erythematosus Disease Activity Index scores (SLEDAI) and adverse reactions...

Although abnormal auditory sensitivity is the most common sensory impairment associated with autism spectrum disorder (ASD), the neurophysiological mechanisms remain unknown. In previous studies, we reported that this abnormal sensitivity in patients with ASD is associated with delayed and prolonged responses in the auditory cortex. In the present study, we investigated alterations in residual M100 and MMFs in children with ASD who experience abnormal auditory sensitivity. We used magnetoencephalography (MEG) to measure MMF elicited by an auditory oddball paradigm (standard tones: 300 Hz, deviant tones: 700 Hz) in 20 boys with ASD (11 with abnormal auditory sensitivity: mean age, 9...

BACKGROUND: BK virus (BKV) is a significant post-transplant infection. Mammalian target of rapamycin inhibitors (mTORis) reduce BKV large T antigen expression in vitro and are associated with lower rates of BKV infection when used as de novo immunosuppression in clinical studies. METHODS: We performed a prospective, single-center, randomized, open label pilot trial to evaluate the impact of mycophenolate mofetil (MMF) withdrawal with conversion to the mTORi everolimus versus a 50% reduction of the MMF dose for the treatment of BKV infection after kidney transplantation...

Sijia Hu, Carolyn A Koh
The interfacial properties and mechanisms of gas hydrate systems play a major role in controlling their interparticle and surface interactions, which is desirable for nearly all energy applications of clathrate hydrates. In particular, preventing gas hydrate interparticle agglomeration and/or particle-surface deposition is critical to the prevention of gas hydrate blockages during the exploration and transportation of oil and gas subsea flowlines. These agglomeration and deposition processes are dominated by particle-particle cohesive forces and particle-surface adhesive force...

Calcineurin inhibitors (CNIs) are frequently given at a reduced dose in combination with mycophenolate mofetil (MMF) to avoid nephrotoxicity, but the optimal reduction in CNI dose has not been established. In this prospective, open-label, multicenter study, liver transplant recipients with chronic renal dysfunction who were administered a CNI-based immunosuppressive regimen were included in the intent-to-treat (ITT) population. The primary endpoint was declination in renal function, which was defined as a ≥ 20% decrease in the glomerular filtration rate during the year following regimen adjustment...

Chaos-based secure communication can provide a high level of privacy in data transmission. Here, we experimentally demonstrate secure signal transmission over two kinds of multimode fiber (MMF) based on electro-optic intensity chaos. High-quality synchronization is achieved in an electro-optic feedback configuration. Both 5  Gbit/s carrier-less amplitude/phase (CAP-4) modulation and 10  Gbit/s on-off key (OOK) signals are recovered efficiently in electro-optic chaos-based communication systems. Degradations of chaos synchronization and communication system due to mismatch of various hardware keys are also discussed...

REVIEW
Jung-Ho Lee
The management of mandibular angle fractures is often challenging and results in the highest complication rate among fractures of the mandible. In addition, the optimal treatment modality for angle fractures remains controversial. Traditional treatment protocols for angle fractures have involved rigid fixation with intraoperative maxillomandibular fixation (MMF) to ensure absolute stability. However, more recently, non-compression miniplates have gained in popularity and the use of absolute intraoperative MMF as an adjunct to internal fixation has become controversial...

BACKGROUND: The identification of pathway(s) playing a pivotal role in peritransplant detrimental inflammatory events represents the crucial step towards a better management and outcome of pancreatic islet transplanted patients. Recently, we candidate the CXCR1/2 inhibition as a relevant strategy in enhancing pancreatic islet survival after transplantation. METHODS: Here, the most clinically used antiinflammatory compounds (IL1-receptor antagonist, steroids and TNF-α inhibitor) alone or in combination with a CXCR1/2 inhibitor were evaluated in their ability to improve engraftment or delay graft rejection...

Progressive multifocal leukoencephalopathy (PML) is an opportunistic infection of the central nervous system caused by JC virus. Only ten cases of PML have been reported so far in liver transplant recipients. We present a case of liver posttransplantation PML with characteristic clinical and brain MRI findings, but with an atypical late onset, developed 11 years after transplantation and after single-drug, long-term (8 years), and low-dose (750 mg twice a day) immunosuppression with mycophenolate mofetil (MMF)...

OBJECTIVES: For decades, Erich arch bars have been a standard in establishing maxillo-mandibular fixation (MMF). While reliable, the approach risks sharps injury, consumes operating room time, and inflicts gingival trauma. Newer technologies including screw-based techniques and "hybrid" techniques have improved MMF by reducing sharps injuries and operating room time, but risk injury to tooth roots, nerves, and gingiva. This study aims to establish the application, strengths, and limitations of dental occlusion ties as a novel alternative in maxillo-mandibular fixation...

BACKGROUND: Mycophenolate mofetil (MMF), the prodrug of mycophenolic acid (MPA), is becoming increasingly popular as an alternative immunosuppressant in feline medicine. Pharmacokinetic information is not available for cats. OBJECTIVE: The purpose of this study was to determine whether MMF is biotransformed into the active metabolite MPA and to evaluate the disposition of MPA after a 2-hour constant rate intravenous (IV) infusion of MMF in healthy cats. ANIMALS: Healthy cats (n = 6)...

Dimethyl fumarate (DMF) is the methyl ester of fumaric acid, after oral administration completely converts to its active metabolite monomethyl fumarate (MMF). A simple, rapid and sensitive LC-MS/MS method was developed and validated for the quantification of MMF in human plasma. Monomethyl fumarate d3 was used as an internal standard (IS). The analyte and the IS were extracted from plasma using a selective solid phase extraction technique. The clean samples were chromatographed on a C18 column using formic acid and acetonitrile (25:75, v/v) as mobile phase...

MMF is commonly prescribed following kidney transplantation, yet its use is complicated by leukopenia. Understanding the genetics mediating this risk will help clinicians administer MMF safely. We evaluated 284 patients under 21 years of age for incidence and time course of MMF-related leukopenia and performed a candidate gene association study comparing the frequency of 26 SNPs between cases with MMF-related leukopenia and controls. We matched cases by induction, steroid duration, race, center, and age. We also evaluated the impact of induction and SNPs on time to leukopenia in all cases...

Social Disorganisation (SD) is a shared autistic and schizotypal phenotype that is present in the subclinical population. Auditory processing deficits, particularly in mismatch negativity/field (MMN/F) have been reported across both spectrum disorders. This study investigates differences in MMN/F cortical spatio-temporal source activity between higher and lower quintiles of the SD spectrum. Sixteen low (9 female) and 19 high (9 female) SD subclinical adults (18-40years) underwent magnetoencephalography (MEG) during an MMF paradigm where standard tones (50ms) were interrupted by infrequent duration deviants (100ms)...
