BACKGROUND Consensus has been lacking as to how to reconstruct the posterolateral corner (PLC) of the knee in patients with posterolateral instability. We describe a new reconstructive technique for PLC based on Larson's method, which reflects the physiological load-sharing pattern of the lateral collateral ligament (LCL) and popliteofibular ligament (PFL). FINDINGS Semitendinosus graft is ha...

Immune suppression mediated by exosomes is an emerging concept with potentially immense utility for immunotherapy in a variety of inflammatory contexts, including allogeneic transplantation. Exosomes containing the apoptosis-inducing molecule Fas ligand (FasL) have demonstrated efficacy in inhibiting antigen-specific immune responses upon adoptive transfer in animal models. We report here that ...

In this report, we show that Epstein-Barr virus (EBV)-infected lymphoblastoid cell lines (LCL) express Fas and tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) receptor 2 and that LCL are lysed following engagement of these receptors by agonist Fas and TRAIL receptor-specific monoclonal antibodies (MAb). We also show that EBV-specific CD4+ T cells mediate bystander lysis of susce...

We introduce LCL covers of closed n-dimensional manifolds by n-dimensional disks and study their properties. We show that any LCL cover of an n-dimensional sphere can be converted to the minimal LCL cover, which consists of 2n+2 disks. We prove that an LCL collection of n-disks is a cover of a continuous n-sphere if and only if the intersection graph of this collection is a digital n-sphere. Us...

A large number of harmonics will be generated in the process transforming high frequency and voltage alternating current (AC) into a constant through power conversion system when high-speed motor is used as generator. The phase-shifting reactor to eliminate for generator systems, LCL filter adjustable inductance are supply this paper. can adjust value time according change output inverter. resu...

A grid-connected inverter’s stability is easily influenced by the system’s internal and external characteristics, especially when inverter connected to grid an LCL filter, which complicates system design operating conditions. To handle problem of disturbance in high-order inverter, a linear active rejection control (LADRC) strategy based on LCCL (which divides capacitor filter into two halves s...

For an inverter with LCL filter, voltage at the point of common coupling (PCC) is equivalent to filter capacitor in practical applications. However, PCC background harmonics will cause distortion grid current. Some problems exist traditional methods for suppression, such as insufficient phase margin, increasing design complexity and computation burden. Thus, a scheme second-order complex-vector...
