Improved Production of Pterostilbene within Escherichia coli By means of Focused Development and Number Strain Engineering.
The aim of this prospective longitudinal study was to examine the association between Cesarean section (CS) and child development and behavior. The sample consisted of 256 children who were born at term without serious perinatal pathologies. Their development and behavior was assessed at the age of four using Ages and Stages Questionnaire (ASQ-3), Children's Behavior Questionnaire and Strength and Difficulties Questionnaire. Multivariate linear regression analyses were conducted to assess the association between CS and child outcomes. CS was associated with better scores in the Problem Solving domain of the ASQ in the whole sample. After stratifying by child sex, the positive association between CS and the Problem Solving domain was significant in boys, while no association was found in girls. Girls were rated less optimally in the Gross Motor domain of the ASQ when born via CS. Mode of birth was not associated with behavioral outcomes.Staphylococcins are antimicrobial peptides or proteins produced by staphylococci. They can be separated into different classes, depending on their amino acid composition, structural complexity, and steps involved in their production. In this review, an overview of the current knowledge on staphylococcins will be presented with emphasis on the information collected in the last decade, including a brief description of new peptides. Most staphylococcins characterized to date are either lantibiotics or linear class II bacteriocins. Recently, gene clusters coding for production of circular bacteriocins, sactipeptides, and thiopeptides have been mined from the genome of staphylococcal isolates. In contrast to class II bacteriocins, lantibiotics, sactipeptides, and thiopeptides undergo post-translational modifications that can be quite extensive, depending on the peptide. Few staphylococcins inhibit only some staphylococcal species, but most of them have proven to target pathogens belonging to different genera and iMites are found in all types of environments, inhabiting also the immediate human environments, including dust from sleeping accommodations, upholstered furniture or carpeted floors.

Dermatophagoides pteronyssinus and Dermatophagoides farinae belong to the most common species in the temperate climate zone. Samples were collected by using a portable vacuum cleaner, into trap-filters installed onto the cap for dusting. Then, mites were isolated by a flotation method with saturated NaCl solution. The Petri dishes were screening under a stereoscopic microscope for presence of mites, then isolated mites were mounted on microscopic slides in Hoyer's medium. Mites were identified to species under the light microscope using phase contrast optics. A total of 724 mites were isolated from 46 of the examined samples, including 666 (91.9%) members of the family Pyroglyphidae. Among them D. pteronyssinus was predominat (62.8% of the total count, with average number 211.22 specimens per 1 gram of dust), followed by D. farinae (24.03%, averagely 150.07 specimens per 1 gram of dust) and Euroglyphus maynei (4.42%, 118.11 specimens per 1 gram of dust). Higher density of house dust mites was associated with the following factors higher age of building, higher number of roommates, higher washing frequency per week, presence of carpeted floor in bedrooms, wooden floors in kitchens, closed kitchen, uphoplstered furniture, absence of pets and unemployed housewives.
Hypertension is a growing clinical problem in pediatric population. Also, the cause of hypertension is usually unknown and it may result from systemic inflammation related to tooth decay.

To estimate the potential association in cross-sectional study between tooth decay and hypertension in children and adolescents.

Study group-65 children diagnosed with primary arterial hypertension; control subjects-44 normotensive children. Blood pressure, dental examination, measurement of salivary cortisol, alpha-amylase, secretory IgA, and lysozyme concentrations were performed in all of the children.

Hyper- and normotensive children had similar peripheral blood morphology and serum biochemical parameters, except of uric acid concentration, which was significantly higher in the study group (p=.047). Salivary evening concentrations of cortisol and alpha-amylase were significantly higher in hypertensive children (p=.002 and p=.004, respectively). Although 24-hr systolic blood pressure (SBP), including daytime and nighttime SBP, correlated with "decay," "microalbuminuria," "BMI," and "glomerular filtration rate" (r>.75, r>.7, r<.68, and r<.43, respectively), in multivariate analysis only "decay" was associated with hypertension both in children and in adolescents (p<.0001).

Tooth decay in children/adolescents might be regarded as a potent trigger factor of hypertension in individuals in whom all other causes of secondary arterial hypertension have been excluded.

The molecular mechanisms underlying plant responses and adaptation to phosphate (Pi) deficiency are unclear. OsbHLH6 (hereafter bHLH6), an uncharacterized rice (Oryza sativa) Pi starvation response gene encoding a basic helix-loop-helix protein, was identified by yeast two-hybrid screening using the phosphate response repressor OsSPX4 (hereafter SPX4) as bait. bHLH6 is expressed in shoots and roots, and its expression is significantly induced in shoots by Pi deficiency. bHLH6 overexpression lines showed Pi accumulation and enhanced Pi starvation responses, including upregulation of Pi starvation-induced genes and longer root hairs. A bhlh6 mutant showed no significant phenotype variation at the seedling stage. A pull-down assay indicated that bHLH6 had higher binding affinity with SPX4 compared to OsPHR2; therefore, bHLH6 competitively inhibited the interaction of SPX4 and OsPHR2. SPX4 overexpression rescued the Pi accumulation caused by bHLH6 overexpression under high- and low-P conditions.
