We investigate the temperature dependence of photon coherence properties through two-photon interference (TPI) measurements from a single quantum dot (QD) under resonant excitation. We show that the loss of indistinguishability is related only to the electron-phonon coupling and is not affected by spectral diffusion. Through these measurements and a complementary microscopic theory, we identify two independent separate decoherence processes, both of which are associated with phonons. Below 10 K, we find that the relaxation of the vibrational lattice is the dominant contribution to the loss of TPI visibility...

Giardia duodenalis is one of the most frequent intestinal parasitic infections in children worldwide. To date, eight main assemblages of G. duodenalis have been described, but only A and B genetic groups are known to infect humans. A cross-sectional study was conducted to determine the prevalence and risk factors of Giardia duodenalis infection in 417 preschool children from the Fomento municipality in the central region of Cuba between January and June 2013. The overall prevalence of Giardia infection was 10...

A novel compound TPI-H containing triphenylimidazole chromophore is synthesized and employed as fluorescent probe for sequential detection of Cu(2+) and S(2-). With three binding sites in its molecular structure, TPI-H exhibits highly selective binding towards Cu(2+) and results in an apparent fluorescence "on-off" behavior. Fluorescence intensity is linear with the Cu(2+) concentration, and the detection limit can be down to 8.7nM. Furthermore, the in-situ generated ensemble between TPI-H and Cu(2+) (TPI-H-Cu(II)) can be used to detect S(2-) with a low detection limit of 15...

Cerebrovascular disease (CVD) is consistently associated with late-life depression but poorly documented in midlife depression. It can be hypothesized that the relatively low sensitivity of conventional neuroimaging techniques does not allow the detection of subtle CVD in midlife depression. We used Tissue Pulsatility Imaging (TPI), a novel ultrasound (US) neuroimaging technique that has demonstrated good sensitivity to detect changes in the pulsatility of small brain volumes, to identify early and subtle changes in brain vascular function in midlife depression...

Although it is well known that solar ultraviolet B (UV-B) radiation enhances plant defenses, there is less knowledge about traits that define insect resistance in field-grown soybean. Here we study the effects of solar UV-B radiation on: a) the induction of phenolic compounds and trypsin proteinase inhibitors (TPI) in soybean undamaged leaves or damaged by Anticarsia gemmatalis neonates during six days, and b) the survival and mass gain of A. gemmatalis larvae that fed on soybean foliage. Two soybean cultivars (cv...

Giardia duodenalis is a common parasitic protozoan in human and animals. Epidemiological and molecular data are available from dairy cattle in many industrialized countries, but information on genetic diversity at multiple genetic loci is limited, especially in pre-weaned dairy calves. In this study, 818 fecal specimens were collected from five dairy cattle farms located in suburbs of Shanghai, China, with two to five samplings per farm. G. duodenalis assemblages and subtypes were determined using multilocus genotyping (MLG) at the β-giardin (bg), glutamate dehydrogenase (gdh), and triosephosphate isomerase (tpi) loci...

Inferring the origins of hybrid taxa based on morphology alone is difficult because morphologically similar hybrids can arise from hybridization between different populations of the same parental species or be produced by hybridization of different parental species. In this study, we investigated the origins of two semi-creeping taxa in Melastoma, which are morphologically similar to a natural hybrid, M. intermedium, by sequencing a chloroplast intergenic spacer, nuclear ribosomal internal transcribed spacer and two low-copy nuclear genes (tpi and cam) in these taxa and their putative parental species...

Triosephosphate isomerase (TPI) is highly expressed in many human cancers and is involved in migration and invasion of cancer cells. However, TPI clinicopathological significance and prognostic value in gastric cancer (GC) are not yet well defined. The aim of the present work was to evaluate TPI expression in GC tissue and its prognostic value in GC patients.TPI expression was analyzed in 92 primary GC tissues and 80 adjacent normal mucosa tissues from GC patients undergoing gastrectomy by immunohistochemical analysis of tissue microarrays (TMAs)...

Little is known about the genetic diversity of the protozoan parasite, Giardia duodenalis, infecting humans in Queensland, Australia. The present study typed 88 microscopically Giardia-positive isolates using assemblage-specific primers at the triose phosphate isomerase (tpi) gene and sequenced a subset of isolates at the glutamate dehydrogenase (gdh) gene (n = 30) and tpi locus (n = 27). Using the tpi-assemblage specific primers, G. duodenalis assemblage A and assemblage B were detected in 50% (44/88) and 38·6% (34/88) of samples, respectively...

Autoantibodies to triosephosphate isomerase (TPI), which is an important glycolytic enzyme in red blood cells and neuronal cells, have been reported to be associated with neuropsychiatric systemic lupus erythematosus (NPSLE) pathogenesis. However, the clinical features regarding anti-TPI antibody (anti-TPI)-positive NPSLE are not yet known. The aim of this study is to investigate the clinical features of anti-TPI-positive NPSLE patients using anti-TPI index values determined by enzyme-linked immunosorbent assay (ELISA)...

OBJECTIVE: This study compares tender point infiltration (TPI) and a tailored neurectomy as the preferred treatment for chronic inguinodynia after inguinal herniorraphy. BACKGROUND: Some 11% of patients develop chronic discomfort after open inguinal herniorraphy. Both TPI and neurectomy have been suggested as treatment options, but evidence is conflicting. METHODS: Patients with chronic neuropathic pain after primary Lichtenstein repair and >50% pain reduction after a diagnostic TPI were randomized for repeated TPI (combined Lidocaine/corticosteroids /hyaluronic acid injection) or for a neurectomy...

REVIEW
Anas Shamsi, Bilqees Bano
Cystatins are thiol proteinase inhibitors (TPI), present ubiquitously in animals, plants and micro-organisms. These are not merely inhibitors rather they are at heart of many pathological conditions ranging from diabetes to renal failure. These are essential for maintenance of protein balance of the cell; once this balance gets disturbed, it may lead to cell death. Thus, cystatins cannot be merely regarded as TPI's as these have been found to play a pivotal role in tumorigenesis and neurodegenerative diseases...

To overcome the limitations of conventional analysis of male fertility in animals and humans, proteomic studies have been performed to develop fertility-related biomarkers for prognosis and diagnosis of male fertility. However, the studies were focused on specific species or breeds. Therefore, a study is required to validate whether fertility-related markers would apply to other breeds in pigs. In this study, previously developed fertility-related biomarkers from Landrace were validated to use for prognosis of male fertility in commercially available breeds...
