This paper estimates multidimensional poverty in Nicaragua between 2001 and 2009, using data from the three most recent standard of living surveys that are available (2001, 2005 and 2009), and mainly following the methodology proposed by Alkire and Foster (2007 and 2011). For that purpose, 10 dimensions and three weighting systems are used: equal-weightings and two other systems based on the data themselves, one based on the first principal component scores, and the other based on the relative frequencies ...

The future of 2D flexible electronics relies on the preparation of conducting ultrathin films of materials with mechanical robustness and flexibility in a simple but controlled manner. In this respect, metal–organic compounds present advantages over inorganic laminar crystals owing to their structural, chemical, and functional diversity. While most metal–organic compounds are usually prepared in bulk, recent work has shown that some of them are processable down to low dimensional forms. Here we ...

The high transmissibility of SARS-CoV-2 before and shortly after the onset of symptoms suggests that only diagnosing and isolating symptomatic patients may not be sufficient to interrupt the spread of infection; therefore, public health measures such as personal distancing are also necessary. Additionally, it will be important to detect the newly infected individuals who remain asymptomatic, which may account for 50% or more of the cases. Molecular techniques are the “gold standard” for the diagnosis ...

Protein physicochemical properties must undergo complex changes during evolution, as a response to modifications in the organism environment, the result of the proteins taking up new roles or because of the need to cope with the evolution of molecular interacting partners. Recent work has emphasized the role of stability and stability–function trade-offs in these protein adaptation processes. In the present study, on the other hand, we report that combinations of a few conservative, high-frequency- ...

Schizophrenia is considered a language related human specific disease. Previous studies have reported evidence of positive selection for schizophrenia-associated genes specific to the human lineage. FOXP2 shows two important features as a convincing candidate gene for schizophrenia vulnerability: FOXP2 is the first gene related to a language disorder, and it has been subject to positive selection in the human lineage. Twenty-seven SNPs of FOXP2 were genotyped in a cohort of 293 patients with schizophrenia ...

Long non-coding RNAs (lncRNAs) participate in the neurodevelopment and species divergence. They also contribute in the etiology of neuropsychiatric disorders. The highly accelerated region 1a (HAR1A) lncRNA is regarded as one of the features of the evolutionary deviation of humans and chimpanzees and participates in specification and migration of neuron especially in cortex. In the current study, we genotyped a single nucleotide polymorphism (SNP) in this lncRNA (rs750697) in a population of Iranian ...

Interaction of Neisseria gonorrhoeae with the oviductal epithelium in vitro was examined in 2 cm length segments obtained after surgical sterilization from users of copper T intrauterine device (IUD) or Norplant® and control women. Segments perfused with N.gonorrhoeae suspensions were incubated from 30 min up to 4 h, fixed, frozen and cut in 6–10 μm sections. Bacteria were detected immunohistochemically with rabbit anti-gonococcal serum followed by light and confocal microscopy. Adhesion and internalization ...

Although previous research focused on private firms has revealed that family involvement generally has an insignificant or negative effect on performance, the effects of family on the performance of non-listed firms has not been tested based on a clearly defined relationship. This study considers the limited evidence regarding the performance of private family firms and the debate about whether lone founder and family firms perform differently. It replicates and provides a deeper examination of ...

Ring-closing olefin metathesis (RCM) catalyzed by Grubbs's ruthenium benzylidene complex 1 is applied to the synthesis of unsaturated rings ranging in size from seven to thirteen members in trans-fused polyether systems. Reaction occurs with great efficiency in the cyclization of oxepene and oxocene rings, but as ring size increases, yields drop. The influence of the final double bond position is also studied. Better yields and milder reaction conditions are observed when an additional oxygen atom ...

The hepatitis B virus (HBV) causes chronic hepatitis, hepatic cirrhosis, and hepatocellular carcinoma. Surface antigen (HBsAg) detection is a definitive test that can confirm HBV infection, while the presence of antibodies against the core protein (anti-HBc) suggests either a previous or ongoing infection or occult hepatitis B infection (OBI).The aim of the present study was to determine the prevalence of anti-HBc and HBsAg in blood donors. Further, the study aimed to estimate the anti-HBc level at ...

Abstract Solitary median maxillary central incisor (SMMCI) syndrome is a complex disorder consisting of multiple, developmental defects involving midline structures of the head, which includes the cranial bones, the maxilla, and its container dentition (specifically the central incisor tooth germ), together with other midline structures of the body. SMMCI may appear as an isolated trait or in association with other midline developmental anomalies. We describe the case of a patient with SMMCI. He presented ...

Abstract Immunoglobulin (Ig) gene rearrangements and oncogenic translocations are routinely assessed during the characterization of B cell neoplasms and stratification of patients with distinct clinical and biological features, with the assessment done using Sanger sequencing, targeted next-generation sequencing, or fluorescence in situ hybridization (FISH). Currently, a complete Ig characterization cannot be extracted from whole-genome sequencing (WGS) data due to the inherent complexity of the Ig ...
