Abstract N6-methyladenosine (m6A) is the most abundant internal modification in eukaryotic mRNA and plays a crucial role in post-transcriptional gene regulation. Recent studies have revealed that m6A modification is dysr...

Ancient myths from the Mediterranean Culture often become a language used to express current social and political anxieties. In the contemporary theatre ancient myths are deconstructed and subverted according to the post...

"We discuss a modification of the evolutionary minority game (EMG) in which agents are placed in the nodes of a regular or a random graph. A neighborhood for each agent can thus be defined and a modification of the usual...

Abstract The ground plane plays an important role on the performance of a planar inverted-F antenna (PIFA). In this regard, the ground plane modification using slots is proposed in this research to obtain a dual band ant...

Abstract Objectives The objectives of this study were: (1) to compare the incidence of effective orifice area (EOA) after either the trans-catheter and surgical aortic valve replacement (SAVR); and (2) to assess the impa...

Los continuos avances en el conocimiento de la biología molecular han permitido un gran progreso de la ciencia, mediante la modificación genética tanto de virus, bacterias como de organismos superiores. Estos procedim...

Abstract Background Prostate cancer (PCa) is a common malignant tumor in men, with a high incidence rate, posing a serious threat to human health and quality of life. Neddylation is a major post-translation modification,...

Antimicrobial resistance represents a major global health challenge, particularly in the context of multidrug-resistant bacteria. Although conventional antibiotics and antimicrobial peptides (AMPs) both exert selective p...

Abstract Proper regulation of ribosome biogenesis is essential for stem cell function and tissue homeostasis, yet its upstream control in adult intestinal stem cells (ISCs) remains unclear. Here, we identify the WD repea...

BACKGROUND: Serum creatinine concentration is widely used as an index of renal function, but this concentration is affected by factors other than glomerular filtration rate (GFR). OBJECTIVE: To develop an equation to pre...

The main objective of this work was to obtain biodegradable nancomposites from polycaprolactone and bentonite with optimized mechanical properties by the chemical modification of the clay (cation exchange reactions). Fir...

Escherichia coli is known to produce enterotoxins whose properties and its role in diarrheal disease has been extensively investigated. Some species of Staphylococcus are often recognized as etiological agents of many an...

La alergia digestiva es una entidad frecuente y diagnosticable en distintas especies. Corresponde a respuestas inmunes anómalas en animales previamente sensibilizados, frente al ingreso por vía oral del antígeno y que...

El objetivo del estudio fue investigar eventuales modificaciones séricas de algunos indicadores metabólico-nutricionales lipídicos en terneros sometidos a destete precoz, maniobra que provoca retrasos de crecimiento. ...

A partir de una breve presentación de los trabajos realizados por el grupo GREAL en la línea de establecer relaciones entre el uso y los conocimientos lingüísticos, el artículo se centra en la investigación realiza...

Este artículo examina la legislación para proteger la salud de las mujeres trabajadoras de la Argentina entre 1934 y 1955. La hipótesis central del texto es que las ideas que se plantearon en los años cuarenta para p...

En algunos países latinoamericanos se observó que la ascites ocurre en diferentes momentos post parto en perras alimentadas con dietas hipoproteicas. El objetivo de este articulo fue describir 2 casos de perras con asc...

"A partir de la necesidad de evitar el vuelco de calidades deficientes de los efluentes, se plantea una optimización de la planta de tratamiento de efluentes líquidos. Para este caso, se ha seleccionado una planta indu...

Much effort has been expended in the aerospace industry in order to achieve the highest quality standards required for nowadays technical and environmental necessities. This involves the increase of specific power and ov...

BACKGROUND: Equations to estimate glomerular filtration rate (GFR) are routinely used to assess kidney function. Current equations have limited precision and systematically underestimate measured GFR at higher values. OB...

A new software suite, called Crystallography & NMR System (CNS), has been developed for macromolecular structure determination by X-ray crystallography or solution nuclear magnetic resonance (NMR) spectroscopy. In contra...

OBJECTIVE: To determine the incidence, cost, and outcome of severe sepsis in the United States. DESIGN: Observational cohort study. SETTING: All nonfederal hospitals (n = 847) in seven U.S. states. PATIENTS: All patients...

The purpose of model selection algorithms such as All Subsets, Forward Selection and Backward Elimination is to choose a linear model on the basis of the same set of data to which the model will be applied. Typically we ...

Chromatin, the physiological template of all eukaryotic genetic information, is subject to a diverse array of posttranslational modifications that largely impinge on histone amino termini, thereby regulating access to th...
