At the heart of the matter: Cardiovascular health challenges among incarcerated women.

Many factors appear to contribute to an increased risk for cardiovascular disease (CVD) among incarcerated women. Imprisonment is associated with a bodyweight gain and an increased prevalence of overweight and obesity. Inadequate physical activity and unhealthy nutrition further contribute to this positive energy balance.

Association Between Serum Lipid Levels in Greek Children with Dyslipidemia and Mediterranean Diet Adherence, Dietary Habits, Lifestyle and Family Socioeconomic Factors.

Our study aimed to investigate a possible correlation between nutritional, lifestyle, behavioral and socioeconomic factors and serum lipid levels in children with dyslipidemia. : In this retrospective, observational study, in 31 children with dyslipidemia, aged 3-14 years, dietary habits, physical activity, hours watching television or playing video games, family's socioeconomic status, weight of children and parents, and duration of breastfeeding were recorded.

Methodological quality of clinical practice guidelines for nutrition and weight gain during pregnancy: a systematic review.

Context: Ensuring a healthy pregnancy and achieving optimal gestational weight gain (GWG) are important for maternal and child health. Nevertheless, the nutritional advice provided during pregnancy is often conflicting, suggesting limited adherence to clinical practice guidelines (CPGs).

Objective: The aim of this review was to identify all CPGs on maternal nutrition and GWG and to critically appraise their methodological quality.

Positively charged cyclodextrins as effective molecular transporters of active phosphorylated forms of gemcitabine into cancer cells.

Positively charged cyclodextrins (PCCDs) are molecular carriers of particular interest for their ability to readily enter into cancer cells. Of main interest, guanidino- and aminoalkyl- PCCDs can be conveniently synthesized and form stable and strong inclusion complexes with various active molecules bearing phosphate groups. We have addressed here the challenge to deliver into cancer cells phosphorylated gemcitabine drugs well known for their instability and inability to permeate cell membranes.

Efficient "green" encapsulation of a highly hydrophilic anticancer drug in metal-organic framework nanoparticles.

Metal-organic frameworks (MOFs) are coordination polymers of interest for biomedical applications. Of particular importance, nanoparticles made of iron(III) trimesate (MIL-100, MIL standing for Material Institut Lavoisier) (nanoMOFs) can be conveniently synthesised under mild and green conditions. They were shown to be biodegradable, biocompatible and efficient to encapsulate a variety of active molecules.

Hydrogen peroxide is produced by E. coli challenged haemocytes and regulates phagocytosis, in the medfly Ceratitis capitata. The active role of superoxide dismutase.

Hydrogen peroxide (H(2)O(2)) participates as a second messenger in cell signaling. In this paper, the role of H(2)O(2) was investigated, in Escherichia coli phagocytosis by the haemocytes of the medfly Ceratitis capitata. Block of H(2)O(2) synthesis by specific enzymic inhibitors, namely N-ethylmaleimide (NEM) for NADPH oxidase and diethyldithiocarbamate (DDC) for SOD, resulted in the increase of E.

Novel polycarboxylated EDTA-type cyclodextrins as ligands for lanthanide binding: study of their luminescence, relaxivity properties of Gd(iii) complexes, and PM3 theoretical calculations.

Novel -type cyclodextrin (CD) derivatives, , and , bearing 6, 7 and 8 bis(carboxymethyl)amino (iminodiacetic acid) groups, respectively, were prepared, and their complexation with Eu(iii), Tb(iii) and Gd(iii) ions was studied. Luminescence titrations and mass spectrometry showed formation of multimetal complexes ( 2 to 3, mainly 3 and exactly 4 metal ions), whereas luminescence lifetime measurements revealed the presence of exchangeable water molecules. Semiempirical quantum mechanical calculations, performed by the PM3 method and assessed by DFT calculations on model ligands, indicated efficient multi-metal complexation, in agreement with the experiment.

A beta integrin subunit regulates bacterial phagocytosis in medfly haemocytes.

We have recently reported that the activation of focal adhesion kinase (FAK) and its downstream targets upon pathogen challenge regulate phagocytosis in medfly haemocytes. The goal of this study was to further explore the signalling pathway underlying the process of phagocytosis. In particular, in this report, we used flow cytometry, RNA interference, enzyme-linked immunosorbent assay, Western blot and immunoprecipitation analysis to demonstrate the haemocyte surface receptor, through which the extracellular signals in response to bacteria are transmitted intracellularly.

Regulators and signalling in insect haemocyte immunity.

The innate immune system of insects relies on both humoral and cellular immune responses that are mediated via activation of several signalling pathways. Haemocytes are the primary mediators of cell-mediated immunity in insects, including phagocytosis, nodulation, encapsulation and melanization. The last years, research has focused on the mechanisms of microbial recognition and activation of haemocyte intracellular signalling molecules in response to invaders.

Elk-1 associates with FAK, regulates the expression of FAK and MAP kinases as well as apoptosis in HK-2 cells.

Focal adhesion kinase (FAK), MAP kinases and the nuclear transcription factor Elk-1 have been reported to be implicated in the same cellular processes, however, their direct or indirect interaction and potential function(s) has not been documented. Here, we explored the association of FAK with Elk-1, the implication of Elk-1 in the regulation of FAK and MAP kinases expression as well as apoptosis, in HK-2 cells. Biochemical and immunofluorescence approaches strongly support the association of low molecular weight protein bands, recognized by FAK antibodies, with Elk-1 or p(ser383)Elk-1.

Innate immunity in insects: surface-associated dopa decarboxylase-dependent pathways regulate phagocytosis, nodulation and melanization in medfly haemocytes.

Phagocytosis, melanization and nodulation in insects depend on phenoloxidase (PO) activity. In this report, we demonstrated that these three processes appear to be also dependent on dopa decarboxylase (Ddc) activity. Using flow cytometry, RNA interference, immunoprecipitation and immunofluorescence, we demonstrated the constitutive expression of Ddc and its strong association with the haemocyte surface, in the medfly Ceratitis capitata.

Elk-1 is a novel protein-binding partner for FAK, regulating phagocytosis in medfly hemocytes.

Focal adhesion kinase (FAK) and its downstream signaling targets, mitogen-activated protein kinase (MAPKs), are implicated in the process of phagocytosis by insect hemocytes. The goal of this study was to explore further the signaling pathways underlining the process of phagocytosis. The combination of bioinformatics, biochemical, and immunofluorescence approaches strongly support the expression of Elk-1-like protein in medfly hemocytes.

A short and convenient chemical route to optically pure 2-methyl chromanmethanols. Total asymmetric synthesis of beta-, gamma-, and delta-tocotrienols.

With use of inexpensive commercially available raw materials, chromanmethanol precursors to the natural beta-, gamma-, and delta-tocotrienols have been prepared in high yield. Enzymatic resolution afforded chiral chromanmethanols in high enantiomeric excess. Subsequent attachment of the farnesyl side chain was high yielding, thus allowing the preparation of asymmetric beta-, gamma-, and delta-tocotrienols in one final step wherein simultaneous deprotection of the phenol and removal of the sulfone group occurs.

Distinct signalling pathways promote phagocytosis of bacteria, latex beads and lipopolysaccharide in medfly haemocytes.

In insects, phagocytosis is an important innate immune response against pathogens and parasites, and several signal transduction pathways regulate this process. The focal adhesion kinase (FAK)/Src and mitogen activated protein kinase (MAPK) pathways are of central importance because their activation upon pathogen challenge regulates phagocytosis via haemocyte secretion and activation of the prophenoloxidase (proPO) cascade. The goal of this study was to explore further the mechanisms underlying the process of phagocytosis.

Apoptosis in medfly hemocytes is regulated during pupariation through FAK, Src, ERK, PI-3K p85a, and Akt survival signaling.

Focal adhesion kinase (FAK) and its downstream signaling targets are implicated in the process of apoptosis induced by external stimuli, in several mammalian systems. In this report, we demonstrate, that medfly (Ceratitis capitata) hemocytes do undergo apoptosis during larval development. In particular, we show using Western blot, ELISA and flow cytometry analysis, that FAK expression silencing in transfected by FAK double-stranded RNA (dsRNA) hemocytes, enhances twofold hemocyte apoptosis, by signaling through Src, MEK/ERK, and PI-3K/Akt signaling pathways.
