Interrupting the hormonal balance of an organism by interfering with hormones and their target receptors gives rise to various problems such as developmental disorders. Collectively, these reagents are known as endocrine disruptors (EDs). Cyclic volatile methyl siloxanes (cVMSs) are a group of silicone polymers that including octamethylcyclotetrasiloxane (D4). In the present study, we examined ...

We study a configuration in matrix theory carying longitudinal fivebrane charge, i.e. a D0-D4 bound state. We calculate the one-loop effective potential between a D0-D4 bound state and a D0–anti-D4 bound state and compare our results to a supergravity calculation. Next, we identify the tachyonic fluctuations in the D0-D4 and D0–anti-D4 system. We analyse classically the action for these tachyon...

This paper proposes D4 FLMS-GSC algorithm interpreted as Daubechies D4 wavelet filter instead of subtractor filter which processes array antenna output. The structure of the proposed D4 FLMS-GSC algorithm has characteristic of reducing the computational requirement one-half compared to the FLMS-GSC algorithm. In addition, we obtain the MSE characteristics and adaptive beampattern of the D4 FLMS...

We define the quantum group D4+ – a free version of demihyperoctahedral D4 (the smallest representative Coxeter series D). In order to do so, we construct analogue property that 4×4 matrix has determinant one. Such analogues determinants are usually very hard for groups in general and our result only holds size N=4. The is then defined by imposing this generalized condition on hyperoctahedral H...

Background: The aim of this research was to evaluate the effects three different titanium (Ti) implant surfaces on viability and secretory functions mesenchymal stem cells isolated from a Bichat fat pad (BFP-MSCs). Methods: Four Ti disks were used as substrate: (I) D1: smooth Ti, control; (II) D2: chemically etched, resembling Kontact S surface; (III) D3: sandblasted, (IV) D4: blasted/etched, N...

Dopaminergic neurotransmission in the prefrontal cortex (PFC) plays an important role in regulating cognitive processes and emotional status. The dopamine D4 receptor, which is highly enriched in the PFC, is one of the principal targets of antipsychotic drugs. To understand the cellular mechanisms and functional implications of D4 receptors, we examined the impact of D4 receptors in PFC pyramid...

D4-GDI is a key regulator of Rho GTPases that have been implicated in several aspects of breast tumorigenesis. We have previously found that D4-GDI was selectively expressed in breast cancer cell lines over normal mammary epithelial cells [45]. In this study, we investigated the expression level of D4-GDI in breast tumor specimens (n = 165) by immunohistochemistry using a validated antibody tha...

Les calpaïnopathies sont des maladies génétiques associées à mutations autosomiques récessives (LGMD-R1), ou beaucoup plus rarement dominantes (LGMD-D4), du gène CAPN3 codant la calpaïne-3. patients souffrent d’une myopathie ceintures lentement progressive. Sur base prévalence estimée de 10 70 par million d’habitants, il existerait en France entre 670 et 4 200 individus atteints calpaïnopathie....
