1 Introduction Zn 4 Sb 3 is known to possess a high thermoelectric figure of merit in the 100–350 °C range, making it the most promising p-type material for waste heat recovery at these temperatures [1]. This excellent performance primarily arises from the extremely low lattice thermal conductivity in this material. A combination of reciprocal and real space diffraction analysis has been under-...

Engineering enhanced transport of zinc to the aerial parts of plants is a major goal in bio-fortification. In Arabidopsis halleri, high constitutive expression of the AhHMA4 gene encoding a metal pump of the P(1B)-ATPase family is necessary for both Zn hyperaccumulation and the full extent of Zn and Cd hypertolerance that are characteristic of this species. In this study, an AhHMA4 cDNA was int...

Nerve growth factor (NGF) controls the growth of sympathetic nerves and is increased in young spontaneously hypertensive rats (SHR). The NGF gene has been linked genetically with hypertension in the SHR strain and may explain high NGF mRNA levels. To test for genetic linkage between the NGF gene and its expression in vivo, we examined renal NGF mRNA levels in male SHR, control Donryu rats (DRY)...

We report a high-resolution gas-phase UPS spectrum of zinc phthalocyanine (ZnPc) together with a detailed analysis of the vibronic structure of the first ionization band, showing that presents the lowest value of the intramolecular reorganization energy experimentally reported for a molecular organic semiconductor.

Metal-response element (MRE)-binding transcription factor-1 (MTF-1) is a zinc-regulated transcriptional activator of metallothionein (MT) genes in mammalian cells. The MRE-binding domain of MTF-1 (MTF-zf) has six canonical Cys(2)-His(2) zinc finger domains that are distinguished on the basis of their apparent affinities for zinc and their specific roles in MRE-binding. In this paper, pulsed alk...

The aim of this study was to evaluate age-related changes and the effect of dietary Zn concentration on morphological and immunological characteristics in the gastrointestinal tract of piglets. A total of 96 purebred Landrace piglets were weaned at the age of 26 ± 1 d, and randomly allocated into 3 treatment groups fed with low (57 mg Zn/kg), medium (164 mg Zn/kg), and high (2425 mg Zn/kg) diet...

Zinc toxicity and Zn-Fe interactions were studied in corn (Zea mays L. var. Barbecue hybrid) grown in hydroponic culture. High Zn greatly reduced the root and shoot fresh weights; increasing Fe largely, but not completely, restored normal growth. Correlation analyses of root and leaf Zn and Fe contents suggested that Zn may interfere with the translocation of Fe; however, Zn toxicity was not as...

Background and Objectives: School children have a high snacking frequency. However, it is poor in nutrients. It is important to provide nutritious snack to support their growth and development. This study aimed to evaluate the nutrient content and sensory properties of a protein- and calcium-rich snack made from a local anchovy (LA), soy protein isolate (SPI), and Bambara groundnut flour (BGF)....

Toxic zinc influx may contribute to selective neuronal death after transient global ischemia. We previously used the high-affinity (K(D) = 27 nm) fluorescent dye mag-fura-5 to detect initial increases in neuronal intracellular free Zn(2+) ([Zn(2+)](i)) associated with brief Zn(2+) exposure. Here we used the specific low-affinity Zn(2+) indicator Newport Green (K(D) = 1 microm) to measure the pe...
