Heterochromatic chromosomal regions undergo large-scale reorganization and progressively aggregate, forming chromocenters. These are dynamic structures that rapidly adapt to various stimuli that influence gene expression patterns, cell cycle progression, and differentiation. Np95-ICBP90 (m- and h-UHRF1) is a histone-binding protein expressed only in proliferating cells. During pericentromeric h...
The influence of sodium hydroxide addition during the thermo-chemical pretreatment of a microbial biomass has been evaluated in terms of particulate chemical oxygen demand (COD) solubilization and anaerobic biodegradability. Both COD solubilization and total solid elimination rates increased with the dose of NaOH added: COD solubilization reached 63%, and total solid elimination was 33% when 5 ...
In a current procedure for periodontal tissue regeneration, enamel matrix derivative (EMD), which is the active component, is mixed with a propylene glycol alginate (PGA) gel carrier and applied directly to the periodontal defect. Exposure of EMD to physiological conditions then causes it to precipitate. However, environmental changes during manufacture and storage may result in modifications t...
The isomerization of phosphodiester functionality of nucleic acids from 3',5'- to a less common 2',5'-linkage influences the complex interplay of stereoelectronic effects that drive pseudorotational equilibrium of sugar rings and thus affect the conformational propensities for compact or more extended structures. The present study highlights the subtle balance of non-covalent forces at play in ...
OBJECTIVE We evaluated the efficacy of a mucoadhesive vaginal gel (MVG, Miphil) with acidic-buffering properties in bacterial vaginosis (BV). STUDY DESIGN Double-blind, placebo-controlled, 12-week trial. SUBJECTS A total of 45 non-pregnant women with BV were enrolled in the trial. Patients were treated with MVG 2.5 g or the corresponding placebo (P) daily for the first week and then every 3...
We show that the complex PT -symmetric periodic potential V (x) = −(iξ sin 2x+ N)2, where ξ is real and N is a positive integer, is quasi-exactly solvable. For odd values of N ≥ 3, it may lead to exceptional points depending upon the strength of the coupling parameter ξ. The corresponding Schrödinger equation is also shown to go over to the Mathieu equation asymptotically. The limiting value of...
