SODIUM/IODIDE SYMPORTER-NIS Abundant and Important in Gastric Mucosa
… constituent in thyroid hormones. Biological mechanisms for iodide uptake and concentration are very important, espe-cially as iodine is a relatively scarce element. Active iodide transport into thyroid fol-licular cells is mediated by the sodium/iodide symporter (NIS), powered by Na+/K+-ATPase. …

Study of selective removal of CoS and NiS during purification of MnSO₄ electrolyte
This research project investigated the selective removal of Co²⁺ and Ni²⁺ from a Co-Ni-Mn system through sulphide precipitation. The Co²⁺ and Ni²⁺ ions have adverse effects on the purity of the manganese product, thus, have to be removed via precipitation in a purification step. The main objective …

Application of radioisotope imaging and therapy in patients with breast carcinomas that express the sodium iodide symporter gene
Aims The Sodium Iodide Symporter (NIS), which is located in the basolateral membrane of the thyroid follicular cell, catalyses an active transport mechanism allowing Iodide, an essential component of the thyroid hormones Tri-iodothyronine(T3) and Thyroxine(T4), to accumulate in the thyroid gland. …

The SYNQ study: SYmptoms, Nutrition, and Quality of life in head and neck cancer survivors
… they are termed nutrition impact symptoms (NIS). Few studies have examined the impact of NIS on nutrition and quality of life in HNC survivors and in those studies, primarily acute effects were investigated. Identifying patients at high-risk for nutritional and/or functional decline …

Integrated Modeling of Agricultural Reactive Nitrogen in the United States: Emissions, Impacts, and Mitigation Strategies
… carbon amendments and nitrification inhibitors (NIs). This study revealed that the Nr emissions are highest in regions with intensive fertilizer use. NH3 is the most damaging, especially in densely populated regions. Impacts of carbon amendments on Nr emissions would vary widely, with net effects …

Distribution and predictors of non-indigenous marine species within South Africa's MPA network
… dissemination of marine non-indigenous (NIS) species across biogeographic borders, little is known about the status of these species within the network of South African marine protected areas (MPAs). Using the most recent data, a target list of NIS was set up for each MPA. Nineteen of the …

A combined approach of electronic structure calculations and spectroscopy for elucidating reaction mechanisms in organic and bioinorganic systems
… (�SR), and nuclear inelastic scattering (NIS). These complementary techniques are used to investigate the structure and mechanism of a variety of important chemical systems, some of which are relevant to biological energy transduction and energy harvesting. The mechanisms by which [FeFe] …

Intensive sampling and comparison of methods in detection of non-indigenous species
Non-indigenous species (NIS) newly introduced to a novel environment usually experience a lag time before the population grows to a detectable level. Management of the NIS during the lag phase provides a better opportunity for eradication than at later stages when the population is larger and …

Nitrification inhibitors have minimal impact on microbial and Collembola communities in Danish arable soil
… non-target impacts of nitrification inhibitors (NIs) on the soil microbial and collembola communities in arable soils under a spring barley cultivation system. By assessing soils where inhibitors were repeatedly applied alongside fertilizers, we evaluated the short-term effects of NI use on soil …

Marine Bioinvasions in Anthropogenic and Natural Habitats: an Investigation of Nonindigenous Ascidians in British Columbia
… distribution of marine nonindigenous species (NIS) spanning several taxonomic groups and geographical regions. Second, I conducted systematic subtidal surveys in anthropogenic and natural habitats and investigated the distribution of nonindigenous ascidians on Southern Vancouver Island, British …

Vegetable intake and head and neck cancer
… collectively known as Nutrition Impact Symptoms (NIS) that can impact the ability and desire to eat. Some prior epidemiological and intervention studies have suggested that increasing intake of vegetables before and following diagnosis with HNC may improve clinical outcomes such as disease …

A study of millerite from Cu-Ni-PGE footwall veins, Sudbury, ON: crystal-chemistry, morphology, & geological implications
Millerite (-NiS) is a common accessory mineral in magmatic Cu-Ni-PGE deposits, such as those occurring in Sudbury, Ontario, Canada. In such localities, millerite develops as platy crystals, often forming large, cleavable masses. This is in stark contrast to the more widespread occurrence of …
