BACKGROUND Intrauterine devices (IUDs) are highly effective and are the most widely used reversible contraceptive method in the world. However, in developed countries IUDs are among the least common methods of contraception used. We evaluated the effect of interventions to increase uptake of the copper IUD, a long-acting, reversible contraceptive method. OBJECTIVES To determine effectiveness ...

BACKGROUND Exposure to particles (PM) induces adverse health effects (cancer, cardiovascular and pulmonary diseases). A key-role in these adverse effects seems to be played by oxidative stress, which is an excess of reactive oxygen species relative to the amount of reducing species (including antioxidants), the first line of defense against reactive oxygen species. The aim of this study was to ...
All-Solid-State Batteries In article number 2206762, Yijie Liu, David Mitlin, and co-workers report a stable anode-free all-solid-state battery (AF-ASSB) with sulfide-based solid-electrolyte (argyrodite Li6PS5Cl). The is achieved by tuning the wetting of lithium metal on “empty” copper current-collector. cover image, sprinting antelope represent cations rapidly diffusing through solid-state sul...
Extracellular proteins of wild-type Vibrio alginolyticus were compared with those of copper-resistant and copper-sensitive mutants. One copper-resistant mutant (Cu40B3) constitutively produced an extracellular protein with the same apparent molecular mass (21 kDa) and chromatographic behavior as copper-binding protein (CuBP), a copper-induced supernatant protein which has been implicated in cop...
When (Samuel Alexander) Kinnier Wilson described a new disease involving the liver and the lenticular nucleus of the brain in 1912, he was unable to recommend any form of treatment, although that remained his life long ambition (Wilson, 1912; Fig. 1). Until the underlying cause of the disease was understood, this inevitably remained a somewhat forlorn hope. A role for copper, as a possible path...
It has become clear that copper toxicity is playing a major role in Alzheimer's disease; but why is the brain copper toxicity with cognition loss in Alzheimer's disease so much different clinically than brain copper toxicity in Wilson's disease, which results in a movement disorder? Furthermore, why is the inorganic copper of supplement pills and in drinking water so much more damaging to cogni...
the interaction of copper oxide nanoparticles and copper ions and proteinase k from tritirachium album limber has been investigated employing uv spectroscopy and kinetics measurements. the aim of this study was to evaluate the effect of nanoparticles of cuo for proteinase k. in this paper we compare the effect of copper oxide nanoparticles with the effect of copper ions on proteinase k stabilit...
One of the most commonly health problems are Respiratory tract infections, almost (5-10) % death cases reported in Centers for Disease Control and Prevention community this increased over years regardless country. As a substitute source electricity many developing countries use electrical generators, but gases materials rising from them will be inhaled surrounding people especially who work on ...
1. Introduction Thompson-Okanagan-Cariboo is an administrative region in south-central BC, established after the province reorganized its natural resource agencies in 2010. Mining predates Confederation and today, the region is home to fi ve of BC's largest metal mines, several industrial mineral mines, and many small placer operations, gravel pits, and rock quarries. power), and skilled worker...
