Before stating Hoeffding’s Inequality, we recall two intermediate results that we will use in order to prove it. One is Markov’s Inequality and other is Hoeffding’s Lemma. (Note that in class we did not cover Hoeffding’s Lemma, and only gave a brief outline of the Chernoff Bounding Techniques and how they are used to prove Hoeffding’s Inequality. Here we give a full proof of Hoeffding’s Inequal...

We have identified and characterized Cab45, a novel 45-kD protein from mouse 3T3-L1 adipocytes. Cab45 is ubiquitously expressed, contains an NH2-terminal signal sequence but no membrane-anchor sequences, and binds Ca2+ due to the presence of six EF-hand motifs. Within the superfamily of calcium-binding proteins, it belongs to a recently identified group of proteins consisting of Reticulocalbin ...

We have recently reported that Ser/Thr phosphatases play a key role in regulating natural killer (NK) cell lytic activity and that calyculin A and okadaic acid affect this activity differently [Bajpai and Brahmi (1994) J. Biol. Chem. 269, 18864-18869]. Here, we investigate a mechanism that might account for this differential action of calyculin A and okadaic acid on NK cells. Calyculin A specif...

Effects of salt stress on absorption and distribution osmotic ions in wheat seedlings were studied with 4 winter varieties under NaCl by exploring dynamic changes Ca2+, K+, Na+, Ca2+/Na+, K+/Na+ Na+ limiting ability. The results showed that the contents Ca2+ ratio gradually decreased a manner both concentration dependent time dependent. extent reduction K+ root was much more severe than shoot. ...

extracellular ca 2+ concentration ([ca2+]o) may be one of the factors affecting atrial natriuretic factor (anf) release. in the previous studies, there are opposite reports about the effect of [ca2+]o on anf secretion. therefore, the effect of [ca2+]o depletion on anf secretion and gene expression was studied in the present research. isolated right atria from rats were perfused for 6 and 2 hour...

In this issue of Neuron, Mankin et al. (2015) show that CA2, an oft-neglected hippocampal subregion, has place representations that change from one episode to the next, even as the spatial environment does not. This finding may help explain how time is encoded in episodic memories.

Individual unstimulated GH4C1 cells exhibited spontaneous dynamic fluctuations in cytosolic free Ca2+ concentration ([Ca2+]i). Either chelation of extracellular Ca2+ with EGTA or treatment with nifedipine inhibited spontaneous [Ca2+]i fluctuations, indicating that the [Ca2+]i profile was dependent on the entry of extracellular Ca2+ via voltage-operated Ca2+ channels (VOCC). Spontaneous [Ca2+]i ...

The role of vacuolar Ca2+ transport systems in regulating cellular Ca2+ was investigated by measuring the vacuolar Ca2+ transport rate, the free energy available to drive vacuolar Ca2+ transport, the ability of the vacuole to buffer lumenal Ca2+, and the vacuolar Ca2+ efflux rate. The magnitude of the Ca2+ gradient generated by the vacuolar H+ gradient best supports a 1 Ca2+:2 H+ coupling ratio...
