Abstract:
BK channels, or voltage-gated Ca2+ channels, are essential regulators of neuronal excitability and muscular contractions, all of which are abnormal in epilepsy, a chronic neuronal disease. The form, frequency, and transmission of action potentials (APs), as well as neurotransmitter release from presynaptic terminals, are all influenced by BK channels found in the plasma membrane of neurons. Over the last two decades, several naturally occurring BK channel modulators have attracted a lot of attention. The structural and pharmacological properties of BK channel blockers are discussed in this art

Abstract:
1. Potassium channels, which control cell electrical activity, are among the most regulated of all ion channels in biology. Promotion of activity in K+ channels by a wide range of physiological factors tends to stabilize cell function. 2. The discovery of synthetic molecules (e.g. cromakalim) that ‘directly’ open ATP-sensitive K+ channels has led to a new direction in pharmacology. ATP-sensitive K+ channel-opening properties have subsequently been demonstrated in a diverse range of chemical structures (synthetic and endogenous). 3. The existence of so many different subtypes of K+ channels has

Abstract:
Monomial codes were recently equipped with partial order relations, a fact that allowed researchers to discover structural properties and efficient algorithm for constructing polar codes. Here, we refine the existing order relations in the particular case of the binary erasure channel. The new order relation takes us closer to the ultimate order relation induced by the pointwise evaluation of the Bhattacharyya parameter of the synthetic channels, which is still a partial order relation. To overcome this issue, we appeal to a related technique from network theory. Reliability network theory was

Abstract:
Endogenous polyamines, in particular spermine, have been found to cause block and modulation of a number of types of ion channel. Intracellular spermine is responsible for intrinsic gating and rectification of strong inward rectifier K+ channels by directly plugging the ion channel pore. These K+ channels control the resting membrane potential in both excitable and non-excitable cells, and control the excitability threshold in neurons and muscle cells. Intracellular spermine causes inward rectification at some subtypes of Ca2+-permeable glutamate receptors in the central nervous system, again

T-type calcium (CaV3) channels are involved in cardiac automaticity, development, and excitation–contraction coupling in normal cardiac myocytes.

To identify novel T-type calcium channel ligands, purpurealidin analogs were electrophysiologically investigated. These compounds are alkaloids produced as secondary metabolites by marine sponges, and they exhibit a broad range of biological activities. In this study,

Chemical and thermal degradation of the elastomers can change the physical properties such as volume, elongation, hardness, tear-strength, and tensile strength. These changes in elastomer phy

Abstract Mild steel was exposed in synthetic sea water to Pseudomonas sp S9 or Serratia marcescens. An increase in the corrosion resistance was observed and monitored by electrochemical techniques. Biological analyses were performed in order to characterize the system. The inhibition effect was also observed when mild steel was coated with bacteria and then inmersed in synthetic sea water. Specimens coated with bacteria were transferred to a natural sea water flow system to investigate if the protective effect was maintained under the new conditions. The preliminary results in natural sea wate

The actual climate crisis is forcing the development of new energy sources that mitigate the negative effects of the climate change. Because of that, the use of fossil fuels is expected to be significantly reduced in the coming decades. In this scenario, the production of renewable fuels that reduce the greenhouse gas emissions (GHG) is one of the main world challenges.

Abstract Several serious problems were encountered in three different cooling water systems during the commissioning of a new synthetic fuels complex in 1992. Fouling of heat exchangers with a silica sediment as well as cases of microbiological growth were found. These problems persisted and after the first year of operation serious corrosion damage, iron precipitation and microbiological fouling of carbon steel exchanger tubes were detected. At that point the need to change the cooling water management philosophy was realized and new tenders were invited for treatment of the systems. The inte

Abstract:
The goal of this work was to understand the role of the enzyme sucrose synthase (SuSy) in synthesis of cellulose and callose in plants. The work resulting from the this grant leads to a number of conclusions. SuSy clearly plays diverse roles in carbon metabolism. It can associate with the plasma membrane of cells undergoing rapid cellulose deposition, such as cotton fibers, developing maize endosperm, gravistimulated pulvini, and transfer cells of the cotton seed. It is also concentrated at sites of high callose deposition (tapetal cells; cell plates). When SuSy levels are lowered by mutation

In order to enhance fiscal sustainability and regain “investment grade” credit rating, in 2011 Colombia implemented a fiscal rule (FR) on the Central Government's structural balance. Investment grade was rapidly attained, and FR targets were complied with, until 2019. Using the Synthetic Control Method, we provide evidence that the FR promoted fiscal discipline. Nevertheless, public debt has increased continuously and is now expected to exceed 60 percent of GDP, in large part driven by the pandemic. We argue that the FR should be reformed so as to incorporate a debt anchor. Using a regime chan

Correspondingly, a new formulation of the vegetation drag coefficient, CD, is developed using field data from a salt marsh in Terrebonne Bay, LA, by conside

Abstract:
Nitrogen (N) plays a dual role in the agri-food system: it is an essential nutrient for all life forms, yet also an environmental pollutant causing a range of environmental and human health impacts. As the plant nutrient needed in greatest quantities, and as a building block of proteins and other biomolecules, N is a necessary part of all life. In the last century, an enormous increase of N turnover in the agri-food system has enabled increasing per-capita food supply for a growing world population, but as an unintended side effect, N pollution has increased to levels widely agreed in science
