The anion exchanger pendrin is present in the apical plasma membrane of type B and non-A-non-B intercalated cells of the cortical collecting duct (CCD) and connecting tubule and is involved in HCO(3)(-) secretion. In this study, we investigated whether the abundance and subcellular localization of pendrin are regulated in response to experimental metabolic acidosis and alkalosis with maintained...
In an increasingly competitive business environment characterized by more globalization, deregulation and technological advances, companies have been looking for ways of differentiating their products and services and also rethinking their business model through leaner operations and reduced costs. In this context, a new practice that has recently gained a lot of attention is the offshore outso...
The activity of ROMK channels in rat kidney tubule cells was assessed as tertiapin-Q (TPNQ)-sensitive current under whole cell clamp conditions. With an external K(+) concentration of 5 mM and an internal K(+) concentration of 140 mM and the membrane potential clamped to 0 mV, TPNQ blocked outward currents in principal cells of the cortical collecting duct (CCD) outer medullary collecting duct ...
On the basis of an in-depth analysis domestic achievements and results experimental methodological works practice expediency widespread use improved technical means technologies for drilling geological exploration wells with complexes counterflush coring (CCD) till depth 300 m upon sedimentary strata is substantiated. During brown coal deposits titanium placers, which convincingly confirm high ...
Ryanodine receptors (RyR) are calcium release channels, playing a major role in the regulation of muscular contraction. Mutations in skeletal muscle RyR (RyR1) are associated with congenital diseases such as malignant hyperthermia and central core disease (CCD). The absence of high-resolution structures of RyR1 has limited our understanding of channel function and disease mechanisms at the mole...
Dopamine inhibits Na+ and water reabsorption in the rat cortical collecting duct (CCD) in the presence of arginine vasopressin (AVP). This inhibition appears to involve the D4 dopamine receptor isoform, which inhibits cAMP production; however, the D1A receptor, which stimulates cAMP production, is also expressed in the CCD. To discriminate between these opposing effects, we measured cAMP produc...
BACKGROUND AND PURPOSE Arterial spin-labeling (ASL) was recently introduced as a noninvasive method to evaluate cerebral hemodynamics. The purposes of this study were to assess the ability of ASL imaging to detect crossed cerebellar diaschisis (CCD) in patients with their first unilateral supratentorial hyperacute stroke and to identify imaging or clinical factors significantly associated with ...
BACKGROUND Canine cognitive dysfunction (CCD) is an age-dependent neurodegenerative condition dominated by changes in behavioral patterns. Cohort studies investigating cognitive status in dogs are lacking. OBJECTIVES To investigate cognitive function, progression of age-related behavioral changes, survival, and possible biomarkers of CCD in aged dogs. ANIMALS Fifty-one dogs >8 years old; 21...
In the rat cortical collecting duct (CCD), the presence of highly specific receptors to calcitonin (CT) coupled to a sensitive adenylate cyclase system suggests that this segment is a target site for CT. Our aim was to explore the effects of CT on the rat CCD microperfused in vitro. The hormone failed to alter the osmotic water permeability and did not affect net Na+ transport but generated a l...
The charge-coupled device (CCD) has been developed primarily as a compact image sensor for consumer and industrial markets, but is now also the preeminent visible and ultraviolet wavelength image sensor in many fields of scientific research including space-science and both Earth and planetary remote sensing. Today’s scientific or science-grade CCD will strive to maximise pixel count, focal plan...
