OBJECTIVES/HYPOTHESIS To describe the speech rehabilitation outcomes of patients undergoing total laryngectomy (TL) in the 21st century. STUDY DESIGN Retrospective chart review. SETTING Tertiary academic center SUBJECTS AND METHODS Retrospective review of 167 patients who underwent TL from June 2000 to February 2012. Demographics, disease variables, and surgical factors were reviewed. Pri...

Hydrothermally-synthesized titanate nanotubes (TNTs) are found to be excellent at adsorption of highly toxic thallium ions. Uptake of both thallium ions is very fast in the first 10 min. The adsorption isotherm of Tl(I) follows the Langmuir model with maximum adsorption capacity of 709.2 mg g(-1). Ion-exchange between Tl(+) and Na(+) in the interlayers of TNTs is the primary mechanism for Tl(I)...

lymphocyte cd4 + count, a standard laboratory test for staging of hiv infection, is expensive and unavailable in resource-restricted countries. total lymphocyte count (tlc) and hemoglobin (hb) are recommended as simple & inexpensive surrogates. the aim of this study was to assess the correlation, sensitivity and predictive power of these parameters as substitutes for cd 4 count. one hundred hiv...

Telomeres are located at chromosome ends and their length (TL) has been associated with aging and human diseases such as cancer. Whole blood DNA is frequently used for TL measurements but the influence of preanalytical conditions and DNA isolation methods on TL quantification has not been thoroughly investigated. To evaluate potential preanalytical as well as methodological bias on TL, anonymiz...

In vivo tests were performed to assess the influence of the protease inhibitor TL-3 on feline immunodeficiency virus (FIV)-induced central nervous system (CNS) deficits. Twenty cats were divided into four groups of five animals each. Group 1 received no treatment, group 2 received TL-3 only, group 3 received FIV strain PPR (FIV-PPR) only, and group 4 received FIV-PPR and TL-3. Animals were moni...

In contrast to broadly expressed classical class I antigens of the major histocompatibility complex, structurally closely related TL antigens are expressed in a highly restricted fashion. Unlike classical class I antigens, TL antigens are not known to be targets of cytotoxic T cells or to mediate graft rejection. Whereas classical class I antigens function as antigen-presenting molecules to T c...

CsTlCl(3) and CsTlF(3) perovskites have been theoretically predicted to be superconductors when properly hole-doped. Both compounds have been previously prepared as pure compounds: CsTlCl(3) in a tetragonal (I4/m) and a cubic (Fm3̅m) perovskite polymorph and CsTlF(3) as a cubic perovskite (Fm3̅m). In this work, substitution of Tl in CsTlCl(3) with Hg is reported, in an attempt to hole-dope the sy...

The gene Toll (Tl) encodes a maternally supplied interleukin 1 receptor-related transmembrane protein, a key component required to establish dorsoventral polarity in the Drosophila embryo. We have isolated Tl homologs of a primitive dipteran, Clogmia albipunctata, and of the beetle Tribolium castaneum. Tribolium Tl protein (Tl) lacks sequences in the C-terminal portion of the cytoplasmic domain...

OBJECTIVE To evaluate the usefulness of (201)Tl-SPECT in differentiating benign from malignant brain tumors. METHODS AND MATERIALS Eighty-eight patients (44 males and 44 females) with 58 high-grade (WHO grade III-IV) and 30 low-grade (WHO grade I-II) tumors were evaluated with (201)Tl-SPECT. (1) Visual assessment was performed by board-certificated radiologists using (201)Tl-SPECT. Tumors wer...

Background → Psychosocial stress has been associated with an increased risk for mental and somatic health problems across the life span. Some studies in younger adults linked this to accelerated cellular aging, indexed by shortened telomere length (TL). In older adults, the impact of psychosocial stress on TL may be different due to the lifetime exposure to competing causes of TL-shortening. Th...
