Acvbp Versus Acvbp Plus Rituximab For Young Patients With Localized Low-Risk Diffuse Large B-Cell Lymphoma: A Study By The Groupe D'etude Des Lymphomes De L'adulte

Introduction: In a prior study, we demonstrated that ACVBP + consolidation was superior to 3 cycles of CHOP + radiotherapy in young patients (pts) with localized aggressive lymphoma (Reyes F et al. N Engl J Med 2005;352:1197). This randomized trial compared in these pts ACVBP vs. ACVBP + a short course of rituximab (R-ACVBP).Methods: untreated pts between 18 and 65y with stage I/II DLBCL and no adverse prognostic factors according to the aa-IPI were eligible. ACVBP consisted of 3 induction cycles given every 2 weeks: doxorubicin (75 mg/m2) day 1, cyclophosphamide (1.2g/m2) day 1, vindesine (2 mg/m2) day 1 and 5, bleomycin (10 mg) day 1 and 5, prednisone (60 mg/m2) day 1 to 5 followed by consolidation with metothrexate, ifosfamide, VP-16 and cytarabine. R-ACVBP consisted of the same regimen combined with 4 doses of rituximab (375 mg/m2) on day 1, 15, 29 and 43. Primary objective was EFS.Results: From 01/04 to 03/08, 223 pts were randomized, 113 in ACVBP and 110 in R-ACVBP arm. Characteristics were: median age 49y (18-65), stage I 63%, extranodal involvement 45%, bulky disease 4%. CR was 94% in ACVBP and 97% in ACVBP arm (ns). With a median follow-up of 43 months, the 3-y EFS was 82% (95% CI, 73% to 88%) in ACVBP and 93% (95% CI, 87% to 97%) in R-ACVBP group (P=0.0487). The 3-y PFS was 83% (95% CI, 74% to 89%) and 95% (95% CI, 89% to 98%) respectively (P=0.0205). OS did not significantly differ with a 3-y estimates of 97% (95% CI, 90% to 99%) for ACVBP and 98% (95% CI, 92% to 100%) for R-ACVBP (P=0.686). In multivariate analysis, a longer PFS was associated with R-ACVBP arm (P=0.0302) and lower b2-m level (P=0.0164). The same proportion of pts (27%) experienced at least 1 SAE in both groups. There were 4 deaths in each arm, with 1 treatment-related death in R-ACVBP (pneumocystis jiroveci pneumonia).Conclusion: the addition of only 4 doses of rituximab to ACVBP significantly improves EFS and PFS in younger pts with low-risk localized DLBCL.

Risk assessment of herbicide mixtures in a large European lake

Lake Geneva is one of the largest European lakes with a surface area of 580 km2. Its catchment area covers 7400 km2, of which approximately 20% is arable land. Monitoring campaigns have been carried out in 2004 and 2005 to determine the contamination of the lake by pesticides. The results highlight the widespread presence of herbicides in water, the measured concentrations for most substances remaining constant in 2004 and 2005. However, for some individual herbicides the concentrations increased drastically (e.g., the herbicide foramsulfuron). We assessed the environmental risk of the herbicides detected in the lake using water quality criteria recently determined for the Swiss environmental protection agency. Furthermore, we assessed the risk of herbicide mixtures, grouped based upon their mode of action. Generally, the risk estimated for all single substances is low, except for some sulfonylurea compounds. For these substances, the measured concentrations are higher than the predicted no-effect concentration. Impact on the flora of the lake can therefore not be excluded. When mixtures of pesticides with similar mode of action are taken into account, the risk remains lower than the mixture water quality criteria for all groups, but can reach as high as one third of this quality criteria. A further step would therefore be to assess the risk of the total pesticide mixture, including similar and dissimilar modes of action

A large deletion in the adRP gene PRPF31: evidence that haploinsufficiency is the cause of disease.

PURPOSE: To report a large deletion that encompasses more than 90% of PRPF31 gene and two other neighboring genes in their entirety in an adRP pedigree that appears to show only the typical clinical features of retinitis pigmentosa. METHODS: To identify PRPF31 mutation in a dominant RP family (ADRP2) previously linked to the RP11 locus, the 14 exons of PRPF31 were screened for mutations by direct sequencing. To investigate the possibility of a large deletion, microsatellite markers near PRPF31 gene were analyzed by non-denaturing PAGE. RESULTS: Initial screening of PRPF31 gene in the ADRP2 family did not reveal an obvious mutation. A large deletion was however suspected due to lack of heterozygosity for nearly all PRPF31 intragenic single nucleotide polymorphysm (SNPs). In order to estimate the size of the deletion, SNPs and microsatellite markers spanning and flanking PRPF31 were analyzed in the entire ADRP2 family. Haplotype analysis with the above markers suggested a deletion of approximately 30 kb that included the putative promoter region of a novel gene OSCAR, the entire genomic content of genes NDUFA3, TFPT and more than 90% of PRPF31 gene. Sequence analysis of the region flanking the potential deletion showed a high presence of Alu elements implicating Alu mediated recombination as the mechanism responsible for this event. CONCLUSIONS: This mutation provides evidence that haploinsufficiency rather than aberrant function of mutated proteins is the cause of disease in these adRP patients with mutations in PRPF31 gene.

Latissimus dorsi muscle-flap over Gore-Tex patch for coverage of large thoracic defects in paediatric Ewing sarcoma.

Primary rib involvement accounts for 16% of paediatric Ewing sarcoma (ES). Neo-adjuvant chemotherapy and surgical tumor resection may leave large thoracic wall defects requiring complex reconstruction in a growing individual. We report our experience in three children aged 3, 10, and 12 years, in whom single-stage resection and reconstruction were performed using a Gore-Tex Dualmesh patch, covered by a latissimus dorsi rotation flap harvested in continuity with the thoracolumbar fascia. The youngest patient also had a vertical expandable prosthetic titanium rib (VEPTR) anchored to help prevent subsequent scoliosis throughout growth.

Stable isotope ecology of Miocene large mammals from Sandelzhausen, southern Germany

The carbon, oxygen, and strontium isotope composition of enamel from teeth of large Miocene herbivorous mammals from Sandelzhausen (MN5, late Early/early Middle Miocene) in the North Alpine foreland basin, were analyzed to infer diet and habitat. The mean enamel delta(13)C value of -11.4 +/- 1.0% (n = 53) for the nine taxa analyzed (including proboscideans, cervids, suids, chalicotheres, equids, rhinocerotids) indicates a pure C(3) plant diet for all mammals. (87)Sr/(86)Sr ratios of similar to 0.710 higher than those from teeth of the western Molasse Basin (0.708-0.709) seem to indicate preferential feeding of the mammals in the northeastern Molasse Basin. The sympatric herbivores have different mean delta(13)C and delta(18)O values which support diet partitioning and/or use of different habitats within a C(3) plant ecosystem. Especially the three sympatric rhinoceroses Plesiaceratherium fahlbuschi, Lartetotherium sansaniense, and Prosantorhinus germanicus show clear partitioning of plants and/or habitats. The palaeomerycid Germanomeryx fahlbuschi was a canopy folivore in moderately closed environments whereas Metaschizotherium bavaricum (Chalicotheriidae) and P. germanicus (Rhinocerotidae) were browsers in more closed forest environments. The horse Anchitherium aurelianense was probably a more generalized feeder than assumed from its dental morphology. The forest hog Hyotherium soemmeringi has the highest delta(13)C and lowest delta(18)O value of all analyzed taxa, possibly related to a frugivorous diet. Most taxa were water-dependent browsers that record meteoric water delta(18)O values of about -5.6 +/- 0.7% Vienna Standard Mean Ocean Water (VSMOW). Using a modern-day mean annual air temperature (MAT)-delta(18)OH(2)O relation a MAT of 19.3 +/- 1.5 degrees C can be reconstructed for Sandelzhausen. A Gomphotherium subtapiroideum tusk serially sampled for delta(18)O values does not record a clear pattern of seasonality. Thus most taxa were C(3) browsers in a forested and humid floodplain environment in the Molasse Basin, which experienced a warm-temperate to subtropical climate and possibly low seasonality.

Epidemiological characterization of Plasmodium falciparum in the Republic of Cabo Verde: implications for potential large-scale re-emergence of malaria

Background: Malaria has come near eradication at archipelago of Cabo Verde in 1970. Infections are now only observed in Santiago, where outbreaks occur. In these islands, malaria is considered by the international community as being of limited risk and, therefore, no prophylaxis is recommended. Since the understanding of factors that determine malaria outbreaks are crucial for controlling the disease, the present study aimed to investigate if the malaria infections observed in Santiago Island are maintained in isolated foci and in asymptomatic individuals.

Large-scale evolutionary trends of Acrochordiceratidae Arthaber, 1911 (Ammonoidea, Middle Triassic) and Cope's rule

Directed evolution of life through millions of years, such as increasing adult body size, is one of the most intriguing patterns displayed by fossil lineages. Processes and causes of such evolutionary trends are still poorly understood. Ammonoids (externally shelled marine cephalopods) are well known to have experienced repetitive morphological evolutionary trends of their adult size, shell geometry and ornamentation. This study analyses the evolutionary trends of the family Acrochordiceratidae Arthaber, 1911 from the Early to Middle Triassic (251228 Ma). Exceptionally large and bed-rock-controlled collections of this ammonoid family were obtained from strata of Anisian age (Middle Triassic) in north-west Nevada and north-east British Columbia. They enable quantitative and statistical analyses of its morphological evolutionary trends. This study demonstrates that the monophyletic clade Acrochordiceratidae underwent the classical evolute to involute evolutionary trend (i.e. increasing coiling of the shell), an increase in its shell adult size (conch diameter) and an increase in the indentation of its shell suture shape. These evolutionary trends are statistically robust and seem more or less gradual. Furthermore, they are nonrandom with the sustained shift in the mean, the minimum and the maximum of studied shell characters. These results can be classically interpreted as being constrained by the persistence and common selection pressure on this mostly anagenetic lineage characterized by relatively moderate evolutionary rates. Increasing involution of ammonites is traditionally interpreted by increasing adaptation mostly in terms of improved hydrodynamics. However, this trend in ammonoid geometry can also be explained as a case of Copes rule (increasing adult body size) instead of functional explanation of coiling, because both shell diameter and shell involution are two possible paths for ammonoids to accommodate size increase.

Human large granular lymphocytes contain an esterase activity usually considered as specific for the myeloid series.

A cytochemical marker such as alpha-naphthyl acetate esterase (ANAE) has been found useful for the morphological identification of the subset of T lymphocytes having receptors for Fcμ (TM cells). ANAE reaction on TM cells gives a typical pattern of one to four positive spots, whereas this pattern is not found on T cells with receptors for Fcγ (TG cells). ANAE is abundant in monocytes but not detectable in granulocytes. Herein another type of esterase activity, naphthol-AS-D chloroacetate esterase (NCAE), is described; it is known to be abundant in granulocytes and was found to give a specific pattern of reactivity with the subpopulation of large granular lymphocytes (LGL). This pattern of fine granular staining was observed not only on LGL present in the TG cell subpopulation but also in LGL present in the non-T, non-B cells. Fractions of peripheral blood mononuclear cells which were ènriched up to 80% in LGL by Percoll discontinuous density gradient gave a similar percentage of specific NCAE pattern. In addition, among the different fractions from Percoll gradient, there was a good correlation (r = 0.94) between the number of NCAE-positive cells and the natural killer activity against the natural killer susceptible K562 target cells. It will be important to determine whether or not this enzymatic activity plays a role in the cytotoxic activities of LGL.

Cashing by the hour: Why large law firms prefer hourly fees over contingent fees

Large law firms seem to prefer hourly fees over contingent fees. Thispaper provides a moral hazard explanation for this pattern of behavior.Contingent legal fees align the interests of the attorney with those ofthe client, but not necessarily with those of the partnership. We showthat the choice of hourly fees is a solution to an agency problem withmultiple principals, where the interests of one principal (law firm)collide with the interests of the other principal (client).

Assignment strategies for large proteins by magic-angle spinning NMR: the 21-kDa disulfide-bond-forming enzyme DsbA.

We present strategies for chemical shift assignments of large proteins by magic-angle spinning solid-state NMR, using the 21-kDa disulfide-bond-forming enzyme DsbA as prototype. Previous studies have demonstrated that complete de novo assignments are possible for proteins up to approximately 17 kDa, and partial assignments have been performed for several larger proteins. Here we show that combinations of isotopic labeling strategies, high field correlation spectroscopy, and three-dimensional (3D) and four-dimensional (4D) backbone correlation experiments yield highly confident assignments for more than 90% of backbone resonances in DsbA. Samples were prepared as nanocrystalline precipitates by a dialysis procedure, resulting in heterogeneous linewidths below 0.2 ppm. Thus, high magnetic fields, selective decoupling pulse sequences, and sparse isotopic labeling all improved spectral resolution. Assignments by amino acid type were facilitated by particular combinations of pulse sequences and isotopic labeling; for example, transferred echo double resonance experiments enhanced sensitivity for Pro and Gly residues; [2-(13)C]glycerol labeling clarified Val, Ile, and Leu assignments; in-phase anti-phase correlation spectra enabled interpretation of otherwise crowded Glx/Asx side-chain regions; and 3D NCACX experiments on [2-(13)C]glycerol samples provided unique sets of aromatic (Phe, Tyr, and Trp) correlations. Together with high-sensitivity CANCOCA 4D experiments and CANCOCX 3D experiments, unambiguous backbone walks could be performed throughout the majority of the sequence. At 189 residues, DsbA represents the largest monomeric unit for which essentially complete solid-state NMR assignments have so far been achieved. These results will facilitate studies of nanocrystalline DsbA structure and dynamics and will enable analysis of its 41-kDa covalent complex with the membrane protein DsbB, for which we demonstrate a high-resolution two-dimensional (13)C-(13)C spectrum.
