Introduction: The objective of the current study was two-fold. First, it aimed to estimate receptive vocabulary and expressive syntax skills in L2 Italian among early sequential/simultaneous bilingual children of migrant single-mother families with very low socioeconomic status (SES). This objective was achieved by matching the participants' performance with normative data.

Article Synopsis
  • * The study evaluated blood samples from COVID-19 positive and negative individuals with coagulopathies, examining factors like PROS1 levels and the presence of SARS-CoV-2.
  • * Findings indicate that SARS-CoV-2 infection reduces PROS1 levels, which may disrupt its anticoagulant functions, suggesting that targeting the PLpro enzyme could help manage coagulation issues in COVID-19 patients.

In this study, we investigated the lexical ability in L1 and L2 of 60 immigrant children who were 37 to 62 months old and exposed to minority languages (L1) and Italian (L2). Using the MacArthur-Bates Communicative Development Inventories, we measured children's vocabulary production in L1 and L2. From interviews, we collected data on quantitative language exposure (parental input, child output, length of exposure to L2 at preschool, and parental oral fluency) and qualitative home-language exposure (HLE) practices (active, play, and passive) in L1 and L2.

Despite the exhaustive screening of gene exons and exon-intron boundaries and promoter region, a significant proportion of mutated alleles remains unidentified in patients with coagulation factor VII deficiency. Here, we applied next-generation sequencing to 13 FVII-deficient patients displaying genotype-phenotype discrepancies upon conventional sequencing, and identified six rare intronic variants. Computational analysis predicted splicing effects for three of them, which would strengthen (c.

Transplantation in patients with congenital bleeding disorders is a challenge requiring an integrated approach of various specialists. Renal transplantation, the most frequent type of solid organ transplantation, is rarely performed in individuals with congenital hemorrhagic disorders. We performed a renal transplantation in a 53-year-old man with end-stage renal disease and congenital coagulation factor VII deficiency, a rare bleeding disorder with a peculiar clinical picture requiring replacement therapy in surgical interventions.

Objectives: This study sought to investigate the evolving pattern over time of on-clopidogrel platelet reactivity (PR) and its relationship with genotype and clinical outcomes after percutaneous coronary intervention.

Background: Whether on-clopidogrel PR and role of genotype differ over time is unknown.

Methods: On-clopidogrel PR before percutaneous coronary intervention, and 1 and 6 months thereafter via VerifyNow P2Y12 (Accumetrics Inc.

The elevated plus-maze is an apparatus composed of enclosed and open (elevated) arms and time spent in the open arms by a rat can be increased/decreased by anxiolytic/anxiogenic agents. In the forced swim test, floating behavior is used as an index of behavioral despair and can be decreased by antidepressant agents. As the comorbidity between anxiety and depression is a remarkable issue in human behavioral disorders, a possible relationship between the behaviors seen in the cited tests is of great relevance.

It has been demonstrated recently that coagulation factor XIII (FXIII) plays an extraordinary role in myocardial healing after infarction, improving survival in a mouse model. Common FXIII gene variants (i.e.

The antimicrobial activity of two garlic clones' (1: purple and 2: white) crude extracts against oral microbiota was evaluated in vitro (study 1) and in vivo (study 2). Study 1 consisted of the evaluation of minimum inhibitory (MIC) and bactericidal (MBC) concentrations against nine streptococci strains. In study 2, a 2.

A common factor V gene haplotype, the FVR2 haplotype (FVHR2), has been associated with a reduced cofactor activity in activated protein C-mediated activated factor VIII inactivation. Our aim was to investigate the role of FVHR2 as a possible determinant of factor VIII levels in a population study. A total of 516 individuals (401 men, 115 women; mean age 58.

Objective: We investigated in patients with ongoing myocardial infarction (MI) whether coagulation factor VII (FVII) and tissue factor (TF) levels are affected at admission by genetic components and whether they may predict subsequent cardiovascular events.

Methods And Results: 256 patients admitted for MI were evaluated for FVII and TF antigen levels before any treatment at entry, and were genotyped for FVII and TF polymorphisms. FVII gene insertions at -323, 11293 and the -402G/A change predicted FVII levels and explained 14% of variance.

Background: Nonsense mutations in coagulation factor (F) VII potentially cause a lethal hemorrhagic diathesis. Readthrough of nonsense mutations by aminoglycosides has been studied in a few human disease models with variable results.

Objectives: We investigated the K316X and W364X FVII mutations, associated with intracranial hemorrhage, and their correction by aminoglycosides.

Objectives: This study evaluated, in vitro, the fracture resistance of bovine roots restored with five different intraradicular post systems.

Method And Materials: Seventy-five bovine roots of similar dimensions were assigned to five groups (n = 15), according to the intraradicular post system used: cast post and core; titanium post; carbon-fiber post; glass-fiber post; and zirconium-oxide post. Following post cementation, the roots were embedded in polystyrene resin composite and submitted to fracture-resistance testing, with a compressive load at an angle of 135 degrees in relation to the long axis of the root at a speed of 0.

In this study, we investigate the influence of three factor VII (FVII) gene polymorphisms on activated FVII levels (FVIIa), and also on the risk of myocardial infarction (MI) in patients with advanced coronary atherosclerotic disease (CAD). The -323A2 allele in the promoter is known to be associated with low FVII levels, and has been suggested to protect against MI in some studies. The -402GA promoter polymorphism, that in vitro has been associated with having opposite effect, is less well studied clinically.

The D allele of the insertion/deletion (I/D) polymorphism of the angiotensin I-converting enzyme (ACE) gene is associated with higher plasma and tissue ACE levels, which enhance the stimulus for neo-intimal hyperplasia. Plaque debulking before stenting reduces the plaque-related determinants of in-stent restenosis and provides an ideal clinical model for studying neointimal hyperplasia. We prospectively studied 113 consecutive patients undergoing elective DCA followed by stent implantation.

We investigated the role of frequent fibrinogen polymorphisms in venous thromboembolic disease in conjunction with inherited thrombophilia. Two hundred unrelated subjects, all carriers of the factor V R506Q mutation (FV Leiden), were genotyped at the fibrinogen gene cluster. Among these subjects, 100 had experienced previous venous thromboembolism (VTE) and 100 were still asymptomatic for VTE.

Objectives: This study was undertaken to assess the role of the gamma knife (GK) in the treatment of meningiomas of the posterior cranial fossa (PCF) and to statistically analyze the predictability of arbitrarily-selected prognostic factors in such treatment.

Methods: From February 1993 to November 1998, 57 patients underwent GK treatment for 62 meningiomas of the PCF (19 M/38 F; average age, 57.5 years, ranging from 25 - 82 years).

Background: Several inherited conditions have been associated with an increased or decreased incidence of retinal vein occlusion (RVO). The A allele in the 20210 G/A prothrombin gene has been found to be associated with systemic venous thrombosis. The aim of this study has been to verify the prevalence of this mutation in patients affected by central RVO (CRVO) or branch RVO (BRVO).

During the past two decades, the progress in computerized treatment planning systems has led to more accurate imaging and therapy by using the gamma knife, especially with the smallest collimators (4 mm). However, the ionization chambers that have been used to calibrate the gamma knife are not useful with the smallest collimators because the chambers are too big compared with the irradiated volume. Therefore, it is important to develop more suitable dosimeters.
