Trimethylamine (TMA) and trimethylamine N-oxide (TMAO) are widespread in the ocean and are important nitrogen source for bacteria. TMA monooxygenase (Tmm), a bacterial flavin-containing monooxygenase (FMO), is found widespread in marine bacteria and is responsible for converting TMA to TMAO. However, the molecular mechanism of TMA oxygenation by Tmm has not been explained. Here, we determined t...

BACKGROUND Trimellitic anhydride (TMA) can induce specific IgE and occupational asthma. The significance of dermal exposure to TMA in immunologic sensitization and on subsequent airway responses is not clearly known. An animal model displaying both an early-phase airway response (EAR) and a late-phase airway response (LAR) after sensitization and subsequent inhalation challenge to a low-molecul...

a long-lasting problem in the analysis of tissue samples is the time-consuming and repetitive process of histologic preparation and pathologic review of tissue sections. these two critical factors, innate nonuniformity in preparation and subjectivity of analysis, therefore limit the scientific and statistical thoroughness of tissue based studies. employing tissue microarray (tma) technique prov...

The thermal atomic layer etching (ALE) of germanium-rich SiGe was demonstrated using an oxidation and “conversion-etch” mechanism with oxygen (O2) or ozone (O3), hydrofluoric acid (HF), trimethylaluminum [TMA, Al(CH3)3] as the reactants. crystalline film prepared physical vapor deposition had a composition Si0.15Ge0.85. In situ spectroscopic ellipsometry employed to monitor thickness both surfa...

BACKGROUND The Association for Pathology Informatics (API) Extensible Mark-up Language (XML) TMA Data Exchange Specification (TMA DES) proposed in April 2003 provides a community-based, open source tool for sharing tissue microarray (TMA) data in a common format. Each tissue core within an array has separate data including digital images; therefore an organized, common approach to produce, navi...

Introduction In addition to glomerular lesion, renal vascular lesion is also an important prognostic marker of lupus nephritis (LN). Among patients with various vascular changes, individuals with thrombotic microangiopathy (TMA) present with severe clinical manifestations and have a high mortality. The aim of the present study was to assess the spectrum and impact of TMA on the outcomes of LN. ...

Abstract Background and Aims Thrombotic microangiopathy (TMA) is a life-threatening condition that can be caused on the background of various mechanisms, converging to severe endotheliopathy often affects kidneys. Morphologic features TMA kidney biopsy have not been systematically studied. We studied diagnostic prognostic role in patients with TMA, either linked coexisting (i.e., secondary TMA)...
