Cellulose Nanocrystal-Based Emulsion of Thyme Essential Oil: Preparation and Characterisation as Sustainable Crop Protection Tool.

Essential oil-based pesticides, which contain antimicrobial and antioxidant molecules, have potential for use in sustainable agriculture. However, these compounds have limitations such as volatility, poor water solubility, and phytotoxicity. Nanoencapsulation, through processes like micro- and nanoemulsions, can enhance the stability and bioactivity of essential oils.

Risks and limits of bariatric surgery: old solutions and a new potential option.

The present review focuses on the side effects that ex-obese patients face following bariatric surgery. We searched through the principal medical indexes (SCOPUS, Web of Science, PubMed, MEDLINE) using the following words, both alone and in combinations: bariatrics; bariatric surgery; anemia; vitamin B12; cobalamin; folate; folic acid; iron; iron supplements; gut microbiota; lactalbumin; α-lactalbumin. To perform exhaustive research, we considered articles published since 1985.

Brain-age is associated with progression to dementia in memory clinic patients.

Background: Biomarkers for the early detection of dementia risk hold promise for better disease monitoring and targeted interventions. However, most biomarker studies, particularly in neuroimaging, have analysed artificially 'clean' research groups, free from comorbidities, erroneous referrals, contraindications and from a narrow sociodemographic pool. Such biases mean that neuroimaging samples are often unrepresentative of the target population for dementia risk (e.

Enhanced Bioactivity of Pomegranate Peel Extract following Controlled Release from CaCO Nanocrystals.

Pomegranate peel extract is rich of interesting bioactive chemicals, principally phenolic compounds, which have shown antimicrobial, anticancer, and antioxidative properties. The aim of this work was to improve extract' bioactivity through the adsorption on calcium carbonate nanocrystals. Nanocrystals revealed as efficient tools for extract adsorption reaching 50% of loading efficiency.

Sex differences in neural correlates of common psychopathological symptoms in early adolescence.

Background: Sex-related differences in psychopathology are known phenomena, with externalizing and internalizing symptoms typically more common in boys and girls, respectively. However, the neural correlates of these sex-by-psychopathology interactions are underinvestigated, particularly in adolescence.

Methods: Participants were 14 years of age and part of the IMAGEN study, a large ( = 1526) community-based sample.

Mentalising and conversation-following in autism.

Some people with autism spectrum disorders have been observed to experience difficulties with making correct inferences in conversations in social situations. However, the nature and origin of their problem is rarely investigated. This study used manipulations of video stimuli to investigate two questions.

Quercetin Loaded Monolaurate Sugar Esters-Based Niosomes: Sustained Release and Mutual Antioxidant-Hepatoprotective Interplay.

Flavonoids possess different interesting biological properties, including antibacterial, antiviral, anti-inflammatory and antioxidant activities. However, unfortunately, these molecules present different bottlenecks, such as low aqueous solubility, photo and oxidative degradability, high first-pass effect, poor intestinal absorption and, hence, low systemic bioavailability. A variety of delivery systems have been developed to circumvent these drawbacks, and among them, in this work niosomes have been selected to encapsulate the hepatoprotective natural flavonoid quercetin.

Synthesis and Evaluation of Saccharide-Based Aliphatic and Aromatic Esters as Antimicrobial and Antibiofilm Agents.

A small library of sugar-based (i.e., glucose, mannose and lactose) monoesters containing hydrophobic aliphatic or aromatic tails were synthesized and tested.

Identification of neurobehavioural symptom groups based on shared brain mechanisms.

Most psychopathological disorders develop in adolescence. The biological basis for this development is poorly understood. To enhance diagnostic characterization and develop improved targeted interventions, it is critical to identify behavioural symptom groups that share neural substrates.

Do ADHD-impulsivity and BMI have shared polygenic and neural correlates?

There is an extensive body of literature linking ADHD to overweight and obesity. Research indicates that impulsivity features of ADHD account for a degree of this overlap. The neural and polygenic correlates of this association have not been thoroughly examined.

Multifocal gastrointestinal stromal tumor: A case report with CT, surgical, and histopathologic correlation.

Mutifocal gatrointestinal stromal tumors (GISTs) are rare conditions that are usually associated with other syndromes or reported in pediatric cases. The sporadic form represents only 11% of GISTs. The imaging features on a contrast-enhanced computed tomography examination, surgery and histopathology of a rare case of a sporadic multifocal small bowel GISTs in an emergency setting are described.

Exploring optimized methoxy poly(ethylene glycol)-block-poly(ε-caprolactone) crystalline cored micelles in anti-glaucoma pharmacotherapy.

Methoxy-poly(ethylene glycol)-b-poly(ε-caprolactone) (mPEG-PCL) polymeric micelles (PMs) open a promising avenue through which ocular drug delivery with superior efficacy and tolerability can be potentially obtained. Methazolamide (MTZ) is an anti-glaucoma drug exhibiting poor corneal penetration, making it an ideal candidate for new polymeric micellar systems. MTZ-PMs were prepared using the thin film hydration procedure and optimized using a Design of Experiment (DoE) approach.

Incorporation of PEGylated δ-decalactone into lipid bilayers: thermodynamic study and chimeric liposomes development.

Liposomes have been on the market as drug delivery systems for over 25 years. Their success comes from the ability to carry toxic drug molecules to the appropriate site of action through passive accumulation, thus reducing their severe side effects. However, the need for enhanced circulation time and site and time-specific drug delivery turned research focus on other systems, such as polymers.

Allele-Specific Methylation of SPDEF: A Novel Moderator of Psychosocial Stress and Substance Abuse.

Objective: Psychosocial stress is a key risk factor for substance abuse among adolescents. Recently, epigenetic processes such as DNA methylation have emerged as potential mechanisms that could mediate this relationship. The authors conducted a genome-wide methylation analysis to investigate whether differentially methylated regions are associated with psychosocial stress in an adolescent population.

Chitosans as new tools against biofilms formation on the surface of silicone urinary catheters.

Urinary catheters contamination by microorganisms is a major cause of hospital acquired infections and represents a limitation for long-term use. In this work, biofilms of Klebsiella pneumoniae and Escherichia coli clinical isolates were developed on urinary catheters for 48 and 72 h in artificial urine medium (AUM) with different molecular weight chitosans (AUM-CS solutions) at pH 5.0.

Inhibition processes are dissociable and lateralized in human prefrontal cortex.

The prefrontal cortex (PFC) is known to make fundamental contributions to executive functions. However, the precise nature of these contributions is incompletely understood. We focused on a specific executive function, inhibition, the ability to suppress a pre-potent response.

Surgery or Peroral Esophageal Myotomy for Achalasia: A Systematic Review and Meta-Analysis.

To date very few studies with small sample size have compared peroral esophageal myotomy (POEM) with the current surgical standard of care, laparoscopic Heller myotomy (LHM), in terms of efficacy and safety, and no recommendations have been proposed.To investigate the efficacy and safety of POEM compared with LHM, for the treatment of achalasia.The databases of Pubmed, Medline, Cochrane, and Ovid were systematically searched between January 1, 2005 and January 31, 2015, with the medical subject headings (MeSH) and keywords "achalasia," "POEM," "per oral endoscopic myotomy," and "peroral endoscopic myotomy," "laparoscopic Heller myotomy" (LHM), "Heller myotomy.

Patient preference and ease of use for different coagulation factor VIII reconstitution device scenarios: a cross-sectional survey in five European countries.

Introduction: Hemophilia A treatment involves replacing the deficient coagulation factor VIII. This process may involve multiple steps that might create a barrier to adherence. A new dual-chamber syringe (DCS; FuseNGo(®)) was recently introduced with the aim of simplifying reconstitution.

Rituximab in previously treated primary immune thrombocytopenia patients: evaluation of short- and long-term efficacy and safety.

The anti-CD20 chimeric monoclonal antibody rituximab has been effectively used in the treatment of patients with primary immune thrombocytopenia (pITP). We retrospectively evaluated 19 patients affected by pITP resistant to 2 or more lines of therapy who were treated with rituximab. Nine of the 19 patients showed an initial response (47.

Replacement of the Y450 (c234) phenyl ring in the carboxyl-terminal region of coagulation factor IX causes pleiotropic effects on secretion and enzyme activity.

The interplay between impaired protein biosynthesis and/or function caused by missense mutations, particularly in relation to specific protein regions, has been poorly investigated. As model we chose the severe p.Y450C mutation in the carboxyl-terminal region of coagulation factor IX (FIX) and, by expression of a panel of recombinant variants, demonstrated the key role of the tyrosine phenyl group for both FIX secretion and coagulant activity.

Central nervous system bleeding in patients with rare bleeding disorders.

Central nervous system (CNS) bleeding is one of the most severe and debilitating manifestations occurring in patients with rare bleeding disorders (RBDs). The aim of this study was to retrospectively collect data on patients affected with RBDs who had CNS bleeding, to establish incidence of recurrence, death rate, neurological sequences, most frequent location, type of bleeding and efficacy of treatments. Results pertained to 36 CNS bleeding episodes in 24 patients with severe deficiency except one with moderate factor VII (FVII) deficiency.

Prevalence of allo-immunization anti-HLA and anti-integrin alphaIIbbeta3 in Glanzmann Thromboasthenia patients.

Platelet transfusions, main therapy of Glanzmann Thromboasthenia (GT), can induce an allo-immunization against human leucocyte antigen and integrin alphaIIbbeta3. We have investigated in our GT patients the rate of allo-immunization and of refractoriness to platelet transfusions. From 1975 until December 2005, we have followed 17 GT patients: 14 type 1, 3 variant type; nine females, eight males; median age at diagnosis 9.
