#1
Daniel J Lewis, Madeleine Duvic
Extracorporeal photopheresis (ECP) has been used for nearly 30 years in the treatment of cutaneous T-cell lymphoma. However, current clinical practice largely reserves ECP for patients with late-stage mycosis fungoides (MF) or Sézary syndrome or for those who are refractory to other therapies. We briefly describe a 48-year-old male who experienced long-term complete remission of his patch MF disease with ECP, and we suggest a role for ECP in the treatment of early-stage MF given evidence of its efficacy, safety, and tolerability...

Yury Minenkov, Giovanni Bistoni, Christoph Riplinger, Alexander A Auer, Frank Neese, Luigi Cavallo
In this work, we tested canonical and domain based pair natural orbital coupled cluster methods (CCSD(T) and DLPNO-CCSD(T), respectively) for a set of 32 ligand exchange and association/dissociation reaction enthalpies involving ionic complexes of Li, Be, Na, Mg, Ca, Sr, Ba and Pb(ii). Two strategies were investigated: in the former, only valence electrons were included in the correlation treatment, giving rise to the computationally very efficient FC (frozen core) approach; in the latter, all non-ECP electrons were included in the correlation treatment, giving rise to the AE (all electron) approach...

We study the binding of the neutral Agn (n = 8, 10, 12) to the DNA base- adenine (A), guanine (G) and Watson-Crick -adenine-thymine (AT), guanine-cytosine (GC) pairs. Geometries of complexes were optimized at the DFT level using the hybrid B3LYP functional. LANL2DZ effective core potential (ECP) was used for silver and 6-31+G(**) was used for all other atoms. NBO charges were analyzed using the Natural population analysis. The absorption properties of Agn-A,G/WC complexes were also studied using time-dependent density functional theory (TDDFT)...

In adults, extracorporeal photopheresis (ECP) is widely utilized for a variety of indications, most commonly cutaneous T-cell lymphoma, acute or chronic graft-versus-host disease (GVHD), solid organ transplant rejection, and other autoimmune and T-cell-mediated disorders. In pediatric patients, the majority of case series and reports have focused on its use in the management of acute and chronic GVHD. Currently utilized ECP technologies were designed for adult patients and there are several challenges in adapting these technologies for use in children...

Riemerella anatipestifer (RA) is the causative agent of infectious serositis in ducklings and other avian species. It is difficult to control the disease due to its 21 serotypes, poor cross-protection, and bacterial resistance to antimicrobial agents. The complement system is an important component of the innate immune system. However, bacterial pathogens exploit several strategies to evade detection by the complement system. Here, we purified and identified a 59-kDa RA extracellular protease S (EcpS) consisting of a gelatinase...

BACKGROUND: Extracorporeal photopheresis (ECP) is an established treatment for graft-versus-host disease (GVHD). Various haematocrit thresholds have been used to trigger red blood cells transfusion prior to ECP. Moderate-to-severe GVHD is frequently complicated by anaemia; the safety and collection efficiency with a lower haematocrit for ECP is unknown. METHODS: We prospectively enrolled 26 consecutive adult GVHD patients with haematocrits between 25% and 28·9% who received ECP on the CELLEX system...

Eight active canonical members of the pancreatic-like ribonuclease A (RNase A) superfamily have been identified in human. All structural homologs share similar RNA-degrading functions, while also cumulating other various biological activities in different tissues. The functional homologs eosinophil-derived neurotoxin (EDN, or RNase 2) and eosinophil cationic protein (ECP, or RNase 3) are known to be expressed and secreted by eosinophils in response to infection, and have thus been postulated to play an important role in host defense and inflammatory response...

Cataract and glaucoma are the leading causes of blindness worldwide and commonly coexist in elderly patients. Endocyclophotocoagulation (ECP) is a minimally invasive approach for glaucoma management that is amenable to combination with cataract surgery. We review the literature on ECP and evaluate intraocular pressure reduction efficacy when combined with phacoemulsification. Several studies demonstrate that phacoemulsification and ECP (PECP) successfully reduces intraocular pressure (IOP) and decreases medication burden...

The reactivity of the carbenoid group 13 metal ligands ECp* (E = Al, Ga) toward low valent transition metal complexes [TM(btsa)2] (TM = Fe, Co, Zn; btsa = bis(trimethylsilyl)amide) was investigated, revealing entirely different reaction patterns for E = Al and Ga. Treatment of [Co(btsa)2] with AlCp* yields [Cp*Co(μ-H)(Al(κ(2)-(CH2SiMe2)NSiMe3)(btsa))] (1) featuring an unusual heterometallic bicyclic structure that results from the insertion of AlCp* into the TM-N bond with concomitant ligand rearrangement including C-H activation at one amide ligand...

2,4-Ditellurouracil exhibits keto-enol tautomerism via different pathways resulting in seven tautomers. These pathways were studied in the gas phase using density functional theory method. The functionals used were BLYP, B3LYP and BHLYP and the basis sets were 6-311++G(d,p) for all atoms except that LanL2DZ ECP was used for tellurium atom only. The results indicate that the diketo form is more stable as observed for uracil and its sulfur and selenium analogues. The effect of introducing fluorine at position 5 was also investigated and the energy difference between the diketo and dienol forms is reduced...

Magnetically induced current density susceptibilities and ring-current strengths have been calculated for neutral and doubly charged persubstituted benzenes C6X6 and C6X6(2+) with X = F, Cl, Br, I, At, SeH, SeMe, TeH, TeMe, and SbH2. The current densities have been calculated using the gauge-including magnetically induced current (GIMIC) method, which has been interfaced to the Gaussian electronic structure code rendering current density calculations using effective core potentials (ECP) feasible. Relativistic effects on the ring-current strengths have been assessed by employing ECP calculations of the current densities...

Extracorporeal photopheresis (ECP) has been used for over 35 years in the treatment of erythrodermic cutaneous T-cell lymphoma (CTCL) and over 20 years for chronic and acute graft-versus-host disease (GvHD) and solid organ transplant rejection. ECP for CTCL and GvHD is available at specialised centres across the UK. The lack of prospective randomised trials in ECP led to the development of UK Consensus Statements for patient selection, treatment schedules, monitoring protocols and patient assessment criteria for ECP...

Two treatments of relativistic effects, namely effective core potentials (ECP) and all-electron scalar relativistic effects (DKH2), are used to obtain geometries and chemical reaction energies for a series of ruthenium complexes in B3LYP/def2-TZVP calculations. Specifically, the reaction energies of reduction (A-F), isomerization (G-I), and Cl(-) negative trans influence in relation to NH3 (J-L) are considered. The ECP and DKH2 approaches provided geometric parameters close to experimental data and the same ordering for energy changes of reactions A-L...

Marine snail egg capsules are shock-absorbing bioelastomers made from precursor "egg case proteins" (ECPs) that initially lack long-range order. During capsule formation, these proteins self-assemble into coiled-coil filaments that subsequently align into microscopic layers, a multiscale process which is crucial to the capsules' shock-absorbing properties. In this study, we show that the self-assembly of ECPs into their functional capsule material is mediated by a bundling protein that facilitates the aggregation of coiled-coil building blocks and their gelation into a prefinal capsule prior to final stabilization...

Electrically conducting polymers (ECPs) are one of the most popular types of materials to interface ion-selective membranes (ISMs) with electron-conducting substrates to construct solid-contact ion-selective electrodes (SCISEs). For optimal ion-to-electron transduction and potential stability, the p-doped ECPs with low oxidation potentials such as PPy need to be generally in their conducting form along with providing a sufficiently hydrophobic interface to counteract the aqueous layer formation. The first criterion requires that the ECPs are in their oxidized state, but the high charge density of this state is detrimental for the prevention of the aqueous layer formation...

REVIEW
T Kanouni, P Aubas, F Heshmati
An apheresis registry is a part of each learned apheresis society. The interest in this is obvious, in terms of knowledge of the practice of apheresis, adverse events, and technical issues. However, because of the weight of data entry it could never be exhaustive and some data will be missing. While continuing our registry efforts and our efforts to match with other existing registries, we decided to extend the data collection to a medico-economic database that is available in France, the Programme de Médicalisation du Système d'Information (PMSI) that has covered reimbursement information for each public or private hospital since 2007...

The dictionary-based approach to the indexing of diffraction patterns is applied to electron channeling patterns (ECPs). The main ingredients of the dictionary method are introduced, including the generalized forward projector (GFP), the relevant detector model, and a scheme to uniformly sample orientation space using the "cubochoric" representation. The GFP is used to compute an ECP "master" pattern. Derivative free optimization algorithms, including the Nelder-Mead simplex and the bound optimization by quadratic approximation are used to determine the correct detector parameters and to refine the orientation obtained from the dictionary approach...

Chronic rhinosinusitis with nasal polyps (CRSwNP) is a multifactorial disease. The pathogenesis of CRSwNP remains unclear. This study was designed to investigate the role of inflammation and Staphylococcus aureus enterotoxin (SE) in this disease. The study included a total of 74 patients with CRSwNP and 6 controls. A serum Phadiatop assay was conducted to detect atopy status, and serum eosinophil cationic protein (ECP) and total immunoglobulin (Ig)E levels were determined using ELISA. SEA, SEB, total IgE, ECP and myeloperoxidase (MPO) levels in nasal tissue supernatant were measured using ELISA...

PURPOSE: We have found that expression of γδT cells is increased in pathological mucosa of chronic rhinosinusitis with nasal polyps (CRSwNP) compared with normal nasal mucosa. This increase is correlated with the infiltration of eosinophils in CRSwNP. Here, we investigated the expression of γδT cells, inflammation and tissue remodeling factors as well as their probable relationships in different types of chronic rhinosinusitis (CRS) in China. METHODS: A total of 76 surgical tissue samples that included 43 CRSwNP samples (15 eosinophilic and 28 non-eosinophilic), 17 CRS samples without nasal polyps (CRSsNP), and 16 controls were obtained...

BACKGROUND: It is well considered that reactive oxygen species (ROS) plays a prominent causative role in the development of allergic rhinitis (AR), and eosinophils cells as important allergic inflammatory cells contribute to elevating oxidative stress. Hydrogen, emerging as a novel antioxidant, has been proven effective in selectively reducing ROS in animals models of oxidative damage. We herein aim to verify protective effects of hydrogen on eosinophils cells in guinea pigs models of AR...
