Mineralização do nitrogênio da palhada de milheto dessecado com herbicidas

Pesquisas recentes verificaram que a utilização de glyphosate ou amônio glufosinate para dessecação de culturas de cobertura em sistemas conservacionistas podem reduzir o conteúdo de nitrogênio na palha formada. Neste contexto. O objetivo deste trabalho foi avaliar a mineralização do N da palhada de milheto em função da utilização dos herbicidas glyphosate e glufosinato de amônio e o aproveitamento do N pela cultura do milho. Utilizou-se o delineamento inteiramente casualizado, com seis tratamentos e cinco repetições, em esquema fatorial 3 x 2, sendo avaliados os fatores: manejo da cultura de cobertura (testemunha sem aplicação de herbicida, dessecação com glyphosate ou glufosinato de amônio) e tipo de solo (Neossolo Quartzarênico órtico típico - NQ e Latossolo Vermelho distrófico típico - LV). A massa de palha seca remanescente nos solos foi maior quando o milheto foi dessecado quimicamente em relação à testemunha. O N-mineral do solo proveniente da palha de milheto, o C-biomassa microbiana e a nitrificação nos tratamentos em que o milheto foi dessecado com herbicidas foram inferiores aos da testemunha. A utilização de dessecantes no milheto não afetou a produção de massa de palha seca e o N-total do milho, embora o conteúdo de N proveniente da palha no milho tenha sido reduzido pela dessecação do milheto com o herbicida glufosinato. A mineralização do N proveniente da palha foi reduzida pela dessecação do milheto com os herbicidas glyphosate e glufosinato de amônio.

How to assign a likelihood ratio in a footwear mark case: an analysis and discussion in the light of R v T

This article analyses and discusses issues that pertain to the choice of relevant databases for assigning values to the components of evaluative likelihood ratio procedures at source level. Although several formal likelihood ratio developments currently exist, both case practitioners and recipients of expert information (such as judiciary) may be reluctant to consider them as a framework for evaluating scientific evidence in context. The recent ruling R v T and ensuing discussions in many forums provide illustrative examples for this. In particular, it is often felt that likelihood ratio-based reasoning amounts to an application that requires extensive quantitative information along with means for dealing with technicalities related to the algebraic formulation of these approaches. With regard to this objection, this article proposes two distinct discussions. In a first part, it is argued that, from a methodological point of view, there are additional levels of qualitative evaluation that are worth considering prior to focusing on particular numerical probability assignments. Analyses will be proposed that intend to show that, under certain assumptions, relative numerical values, as opposed to absolute values, may be sufficient to characterize a likelihood ratio for practical and pragmatic purposes. The feasibility of such qualitative considerations points out that the availability of hard numerical data is not a necessary requirement for implementing a likelihood ratio approach in practice. It is further argued that, even if numerical evaluations can be made, qualitative considerations may be valuable because they can further the understanding of the logical underpinnings of an assessment. In a second part, the article will draw a parallel to R v T by concentrating on a practical footwear mark case received at the authors' institute. This case will serve the purpose of exemplifying the possible usage of data from various sources in casework and help to discuss the difficulty associated with reconciling the depth of theoretical likelihood ratio developments and limitations in the degree to which these developments can actually be applied in practice.

Lymphocyte specificity to protein antigens. V. Conformational dependence of activation of cytochrome c-specific T cells.

Variations in the immunogenic and antigenic properties of native and denatured forms of cytochrome c were observed depending on the strain of mouse tested. In C57BL/6 and (C57BL/6 X DBA/2)F1 (BDF1) mice, priming with either native or denatured cytochrome c (apocytochrome c) gave rise to T cell blasts responding in a similar fashion to the two forms of the antigen and to different peptides derived from CNBr cleavage of the protein when tested for proliferation in the presence of C57BL/6 or BDF1 accessory cells. A different pattern of proliferation was observed when apocytochrome c-specific DBA/2 or BDF1 T cell blasts were tested with DBA/2 accessory cells. In this case, no response was obtained to heme peptide 1-65. This was not due to an inability of DBA/2 macrophages to process and present heme peptide 1-65, as they were able to present this antigen to native cytochrome c-specific BDF1 T cell blasts. Thus, it seems that different sets of clones are generated upon priming BDF1 mice with denatured cytochrome c which are able to recognize different sets of peptides depending on the nature of the accessory cells. The results obtained are consistent with the hypothesis that degradation and presentation of native and denatured cytochrome c by macrophages is dependent on the three-dimensional conformation of the protein.

PRECISION V: Randomisierte Phase II-Studie mit Drug Eluting Beads (DEB) zur Behandlung des hepatozelluläre Karzinoms (HCC) mittels transarterieller Chemoemblisation [PRECISION V: Randomized Phase II-Study with Drug Eluting Beads (DEB) for the Treatment of Hepatocellular cancer (HCC) using transarterial Chemoemblisation.]

Zielsetzung: Vergleich von Drug Eluting Bead (DEB)-TACE mit konventioneller TACE bei der Behandlung von ,,intermediate stage-HCC bei Patienten mit Zirrhose. Material und Methodik: 212 Patienten (185 ♂, 27 ♀; mittleres Alter, 67 Jahre) mit Child-Pugh A oder B Leberzirrhose und großem und/oder multinodulärem, irresektablen HCC wurden randomisiert, um das Therapieansprechen nach der Behandlung mit DEB (DC Bead; Biocompatibles, UK) beladen mit Doxorubicin oder konventioneller TACE mit Doxorubicin zu vergleichen. Die Randomisierung wurde nach Child-Pugh Status (A oder B), Performance Status (ECOG 0 oder 1), bilobärer Erkrankung (ja/nein) und frühere kurative Behandlung (ja/nein) stratifiziert. Der primäre Studienendpunkt war das 6-Monats-Tumoransprechen. Eine unabhängige verblindete MRT-Studie wurde durchgeführt, um das Tumoransprechen nach den RECIST Kriterien zu beurteilen. Ergebnisse: DEB-TACE mit Doxorubicin zeigte eine höhere Rate an komplettem Tumoransprechen, objektivem Ansprechen und Tumorkontrolle im Vergleich zur konventionellen TACE (27% vs 22%; 52% vs 44%; and 63% vs 52%; P>0.05). Patienten mit Child-Pugh B Zirrhose, ECOG 1 Performance Status, bilobärer Erkrankung und Rezidiven nach kurativer Behandlung zeigte einen signifikanten Anstieg des objektiven Ansprechens (p = 0.038) im Vergleich zur Kontrollgruppe. Bei Patienten, die mit DEB-TACE behandelt wurden, konnte eine deutliche Reduktion der gravierenden Lebertoxizität erreicht werden. Die Doxorubicin-Nebenwirkungsrate war in der DEB-TACE Gruppe deutlich geringer (p = 0.0001) als in der konventionellen TACEGruppe. Schlussfolgerung: DEB-TACE mit Doxorubicin ist sicher und effektiv in der Behandlung von ,,intermediate-stage HCC und bietet einen signifikanten Vorteil bei Patienten mit fortgeschrittener Erkrankung.
