In the teleost retina, cone horizontal cells contain a voltage-activated sustained calcium current, which has been proposed to be involved in visual processing. Recently, several studies have demonstrated that modulation of voltage-gated channels can occur through activation of metabotropic glutamate receptors (mGluRs). Because glutamate is the excitatory neurotransmitter in the vertebrate reti...

It is shown that a set-valued map M : R ⇒ R is maximal monotone if and only if the following five conditions are satisfied: (i) M is monotone; (ii) M has a nearly convex domain; (iii) M is convex-valued; (iv) the recession cone of the values M(x) equals the normal cone to the closure of the domain of M at x; (v) M has a closed graph. We also show that the conditions (iii) and (v) can be replace...

Human thyroid epithelial cells were isolated from surgically resected human thyroid gland with collagenase and cultured for one week under EGF-supplemented conditions to allow them to proliferate. Then the cells were transferred to the following three-dimensional culture systems. One was a culture of isolated cells between floating double layers of collagen gel, designated the "floating sandwic...

Tidewater glaciers are glaciers that terminate in, and calve icebergs into, the ocean. In addition to the influence that tidewater glaciers have on physical and chemical oceanography, floating icebergs serve as habitat for marine animals such as harbor seals (Phoca vitulina richardii). The availability and spatial distribution of glacier ice in the fjords is likely a key environmental variable ...

The aim of the present study was to prepare and evaluate floating microspheres consisting of (i) calcium silicate (CS) as porous carrier; (ii) amoxicillin and (iii) hydroxypropyl methylcellulose (HPMC) and ethylcellulose (EC) as polymers. The floating microspheres were evaluated for particle size, micromeritic properties, percent drug content, in vitro floating behavior, and in vitro drug relea...

In development of floating photovoltaic generation system, finding a suitable place of installation is as important as development of economically feasible and stable structure. Especially since floating photovoltaic system has its facility floating on water surface, it is extremely important to review the effects of weather conditions such as wind, water flow and floating matters, various fact...
