Polymer/silica (PS) nanocomposites are, among numerous combinations of inorganic/organic nanocomposites, one of the most important materials reported in the literature and have been employed in a wide variety of applications. Due to this great interest in the scientific and industry community, knowledge about their physiochemistry allows for a better understanding of their development and improvement. One area of interest found in biopolymers is silica, where silica nanoparticles can be used to increase their mechanical properties and give them higher opportunities to replace synthetic plastics.

Objective: We investigated the incidence, clinical characteristics, risk factors, and outcomes of ACS in patients with COVID-19 in the emergency department.
Methods: We retrospectively reviewed all COVID-19 patients diagnosed with ACS in 62 Spanish emergency departments between March and April 2020 (the first wave of COVID-19).
Introduction: Adherence is a cornerstone of factor VIII prophylactic treatment. Information regarding the factors with potential influence on adherence is limited, particularly in adult patients.
Aim: To assess adherence in adult patients with severe haemophilia A receiving prophylactic treatment in a real-life setting, and investigate the factors influencing adherence.

The migration of cancer cells is highly regulated by the biomechanical properties of their local microenvironment. Using 3D scaffolds of simple composition, several aspects of cancer cell mechanosensing (signal transduction, EMC remodeling, traction forces) have been separately analyzed in the context of cell migration. However, a combined study of these factors in 3D scaffolds that more closely resemble the complex microenvironment of the cancer ECM is still missing.

Methods: A total of 107 elite male outfield players were prospectively followed for six seasons. Players were genotyped for 37 SNP previously investigated in relation to musculoskeletal injuries.
I-DNASE21 is a new STR multiplex system that amplifies 21 STR autosomal loci, plus the amelogenin locus in one reaction. This system has been designed to analyze all the STR loci included in the Combined DNA Index System (CODIS), Interpol Standard Set of Loci (ISSL), Extended European Standard Set (ESS-Extended), UK National Criminal Intelligence DNA Database (NDNAD) and German Core loci (GCL). This manuscript presents the validation of the I-DNASE21 system according to the revised guidelines issued by the Scientific Working Group on DNA Analysis Methods (SWGDAM).

However, both residual and emergent viral infections are still responsible for contaminations in recipients of blood products. Along with other viruses (human herpesvirus‑8, human parvovirus B19, hepatitis A and E viruses, etc.

Ten X chromosome markers (DXS6789, DXS6809, DXS7132, DXS7133, DXS7423, DXS8378, DXS9898, DXS9902, GATA172D05, and GATA31E08) were analyzed in a sample of 185 unrelated autochthonous Basques from Navarre. Deviations from Hardy-Weinberg equilibrium and linkage disequilibrium between markers were not observed at any loci. Combined power of discrimination was 0.

It is especially important to generate mtDNA databases from isolated populations in order to maximize the power of discrimination of this molecular marker. It also represents a useful approach to carry out a more accurate haplogroup classification.

The European source population, that of the Basque Country, has long been a cultural and geographical isolate. Previous studies have demonstrated that Y-STR frequencies of Basques are different from those of other Spanish and European populations [1].

I-DNADuo, with amplicon sizes ranging from 57 to 298 bp, is specifically designed to analyse amelogenin and 15 STR loci (ten of them plus amelogenin in duplicate), including all the STR loci of the CODIS, ISSL and ECL databases, and seven of the eight in GCL. The validation of I-DNADuo shows that it is a highly sensitive, robust multiplex system for obtaining individual genetic profiles and for detecting and preventing allelic dropouts.

It was the objective of this study to evaluate convenience and patient satisfaction with the use of SintromacWeb, a new OAT telecontrol system, compared with the conventional control. SintromacWeb consists of a point-of-care device for patient international normalized ratio (INR) self-testing and software that allows internet mediated interaction with physicians.

Design: Cross-sectional diagnostic study.
Methods: 216 patients admitted consecutively to the cardiology section of an academic hospital with a suspected diagnosis of heart failure in a period of 12 months.
Gross deletions in the F9 gene are easily detected by routinely sequencing hemophilia B-affected men. Nevertheless, a carrier diagnosis proves difficult as the presence of a normal allele does not recognize the partial or complete loss of the F9 gene and may be challenging if no DNA sample from affected men is available. This work aimed to identify hemophilia carriers in 2 families in which gross deletions of the F9 gene could be expected.

The fibrous dysplasia is a benign although progressive dysfunction, in which a gene mutation originates the production of fibrous disorganized bony matrix. The bony tissue is replaced by bony tissue in expansion (amorph conjuntival tissue) that produces bony deformities in some patients, pain, pathological fractures or deambulation disorders. The diagnosis is important since ocasionally the first symptom is the fracture.

Five members of the same family were studied. The two patients showed borderline VWF levels, a mild factor VIII (FVIII) deficiency and a decrease of the binding of VWF to exogenous FVIII.
