Introducción: La presencia de variantes débiles del grupo sanguíneo A representa un desafío en la práctica de la inmunohematología por las discrepancias en el momento de la tipificación. Es común en bancos de sangre realizar una tipificación directa e inversa con el objetivo de confirmar el grupo sanguíneo; sin embargo, no todas las personas que presentan un subgrupo sanguíneo A2 han desarrollado anticuerpos anti-A1, lo que dificulta la identificación de subgrupos de A. Objetivo: El presente estudio es descriptivo, observacional y transversal, y tiene el objetivo de establecer la proporción de los subgrupos del antígeno A en donantes de sangre mediante la técnica manual en tubo con reactivos hemoclasificadores monoclonales: anti A, anti-A1 (extracto de las lectinas Dolichus biflorus) y anti-H...

The physical model test of landslides is important for studying landslide structural damage, and parameter measurement is key in this process. To meet the measurement requirements for deep displacement in landslide physical models, an automatic flexible inclinometer probe with good coupling and large deformation capacity was designed. The flexible inclinometer probe consists of several gravity acceleration sensing units that are protected and positioned by silicon encapsulation, all the units are connected to a 485-comunication bus...

Currently, there is a strong global trend towards the development of in vitro models to replace the use of animals in safety evaluation tests. Reconstructed Human Epidermis (RHE) models have been employed as an alternative method to animal testing of skin corrosion and irritation potential of chemical compounds. However, the consequences of an absence of the dermal compartment in these models should be considered since the cross-talk between fibroblasts and keratinocytes is fundamental for promoting proper epidermal stratification, homeostasis, inflammatory response and wound healing...

One of the key environmental factors affecting plant reproductive systems is temperature. Characterising these effects is especially relevant for some commercially important genera such as Citrus. In this genus, failure of fertilisation results in parthenocarpic fruit development and seedlessness, which is a much prized character. Here, we characterise the effects of temperature on flower and ovary development, and on pollen-pistil interactions in 'Comune' clementine (Citrus clementina Hort. ex Tan.). We examine flower-bud development, in vitro pollen germination and pollen-pistil interaction at different temperatures (15, 20, 25 or 30 °C)...

Según la Real Academia Española, el término «líder» significa «persona que dirige u orienta a un grupo, que reconoce su autoridad». Es importante este término ya que es muy ambiguo, porque no reconoce el nivel moral o la empatía que puede ejercer una persona en determinado grupo al reconocerlo como líder, y no solo con la autoridad que este puede ejercer en el mismo, siendo este último concepto algo muy común en el mundo anglosajón, denominándose líder a alguien que tiene un puesto de autoridad, lo cual se puede confundir con lo que conocemos como «jefe»...

Chronic skin wounds affect ≈3% of persons aged >60years (Davies et al., 2007) [1]. These wounds are typically difficult to heal by conventional therapies and in many cases they get infected making even harder the regeneration process. The antimicrobial peptide (AMP) LL37 combines antimicrobial with pro-regenerative properties and thus represents a promising topical therapy to address both problems. Here, we investigated the wound healing potential of soluble and immobilized LL37 (LL37-conjugated gold nanoparticles, LL37-Au NPs), both in vitro (migration of keratinocytes) and in vivo (skin wound healing)...

Sporadic colorectal cancer (CRC) is traditionally diagnosed after de sixth decade of life, although a small percentage of cases are diagnosed in patients under 40 years of age, and incidence is increasing. There exists a great volume of controversy regarding clinical outcome of young patients diagnosed with colorectal cancer (CRC) when compared to elder counterparts. Our aims were to evaluate the rate of CRC in young patients, to review the pertaining literature and to discuss outcomes and clinical prognosis...

We herein describe two cases of secondary syphilis in patients with human immunodeficiency virus (HIV) infection with an unusual presentation, a diffuse polyostotic periosteitis. Patients referred mainly intense bone pain. Other relevant aspects of the clinical pictures were flexor tenosynovitis and hepatic abnormalities. Given the persistence of symptoms, the treatment duration performed was different from most described in literature. However, although more slowly than expected, both obtained a favorable clinical response after treatment with benzathine penicillin G...
