Caracterização botânica e química de Rudgea viburnoides (Cham.) Benth., (Rubiaceae)

Congonha, congonha-de-bugre and bugre are popular names for several medicinal plant species, including Rudgea viburnoides (Cham.) Benth. (Rubiaceae), whose leaves are widely used in popular medicine as diuretic, hypotensive, antirheumatic, and blood depurative. This species has been commercialized as porangaba, and used for diet purposes in substitution of Cordia ecalyculata Vell...

De lactante a niño: alimentación en diferentes etapas

Proper nutrition during childhood is necessary to: allow adequate growth and development, achieve optimal physical and psychic performance, maintain and improve health and recover more easily in disease processes. The first months of life (the infant stage) are a stage in which many rapid changes take place (anthropometric, body composition, maturation of organs and systems...

A crash course in sequencing for a microbiologist

For the last 40 years, “Sanger sequencing” allowed to unveil crucial secrets of life. However, this method of sequencing has been time-consuming, laborious and remains expensive even today. Human Genome Project was a huge impulse to improve sequencing technologies, and unprecedented financial and human effort prompted the development of cheaper high-throughput technologies and...

Differentiation between blood and iodine in a bovine brain—Initial experience with Spectral Photon-Counting Computed Tomography (SPCCT)

Objectives To evaluate the accuracy of Spectral Photon-Counting Computed Tomography (SPCCT) in the quantification of iodine concentrations and its potential for the differentiation between blood and iodine. Methods Tubes with blood and a concentration series of iodine were scanned with a preclinical SPCCT system (both in vitro and in an ex vivo bovine brain tissue sample). Iodine...

Efecto de la Adición de Jarabes de Sacarosa y Fructosa en el Comportamiento Reológico de Miel de Abejas

The effect of the addition of saccharose and fructose syrups on the rheological properties of honey produced in two regions, Sabanas and Montes de María, in the Department of Sucre in Colombia was determined. Sucrose or fructose syrup in percentages of 0, 10, 20, 30, 40 and 50% were added to pure honey. The rheological properties were determined using a TA Instruments rheometer...

Determinação do fator de cobertura do melão cultivado sob diferentes lâminas e salinidades da água de irrigação

Two experiments were carried out with the objective of comparing methodologies for determination of the soil cover factor of melon when submitted to different conditions of water depths and salinity, in Mossoro, RN. The experimental design was of completely randomized blocks in a 2 x 2 x 6 factorial scheme. Two methods were tested (Stocking's and ruler), two salinity levels (0.55...

The British Polio Fellowship: its contribution to the development of inclusivity for disabled people

The organizations set up to cope with polio in the years of epidemic outbreaks in Europe constitute an interesting focus in historiography as an example of contemporary patients' associations and mutual aid groups. The main aim of this paper is to reconstruct and analyse the principal highlights in the birth and development of the British Polio Fellowship (BPF) and its historical...

Evidence that a catalytic glutamate and an ‘Arginine Toggle’ act in concert to mediate ATP hydrolysis and mechanochemical coupling in a viral DNA packaging motor

ASCE ATPases include ring-translocases such as cellular helicases and viral DNA packaging motors (terminases). These motors have conserved Walker A and B motifs that bind Mg2+-ATP and a catalytic carboxylate that activates water for hydrolysis. Here we demonstrate that Glu179 serves as the catalytic carboxylate in bacteriophage λ terminase and probe its mechanistic role. All...

A randomised pilot equivalence trial to evaluate diamagnetically enhanced transdermal delivery of key ground substance components in comparison to an established transdermal non-steroidal anti-inflammatory formulation in males with prior knee injury

Objective This pilot study assessed the efficacy of a knee guard device, which used magnetophoresis to transdermally deliver Glucosamine, Chondroitin and Hyaluronic Acid in a cohort of individuals with prior knee injury. The aim was to determine if the change in physical function and pain with the knee guard device was equivalent to the change produced by an established topical...

The Genetics of Treatment-Resistant Depression: A Critical Review and Future Perspectives

One-third of depressed patients develop treatment-resistant depression with the related sequelae in terms of poor functionality and worse prognosis. Solid evidence suggests that genetic variants are potentially valid predictors of antidepressant efficacy and could be used to provide personalized treatments.

Psalm 16 (LXX ps 15) and Acts of the Apostles part II

Psalm 16 is one of the most well-known texts of the Psalter. This can be attributed to, amongst other things, the fact that the NT, specifically Acts of the Apostles, applied this text to the life of Jesus of Nazareth. The quotations from Psalm 16 in the book of Acts thus got a messianic-Christological meaning. If we, however, take a look at the text of Psalm 16, it seems that...

Efeitos da compactação em algumas propriedades físicas do solo e seu reflexo no desenvolvimento das raízes de plantas de soja

The effects of an artificial soil compaction on soil density, total porosity and soil resistance to penetration were studied with the aim to determine the level that obstructs root development of soybean. The work was carried out in greenhouse, with disturbed samples of surface horizon of an Ultisol ("Terra Roxa Estruturada") and an Oxisol ("Latossolo Roxo"), and controlling the...

Características operacionais das intervenções coronárias percutâneas em centro que prioriza a utilização do acesso radial

BACKGROUND: The radial approach has demonstrated superior benefits to the femoral approach in reducing vascular complications and bleeding events associated to percutaneous coronary interventions. However, because this is a more complex procedure, it requires a learning curve to get all of the advantages of the technique. The aim of this study was to present the characteristics...

As Told to G/D Thyself

This is a review of the Sundance short film, As Told to G/D Thyself (2019), directed by Terence Nance, Jenn Nkiru, Marc Thomas, Kamasi Washington, and Bradford Young; collectively known as the Ummah Chroma.

Root-endophytic Chaetomium cupreum chemically enhances aluminium tolerance in Miscanthus sinensis via increasing the aluminium detoxicants, chlorogenic acid and oosporein

Miscanthus sinensis Andersson is a pioneer plant species that grows naturally at mining sites. Miscanthus sinensis can detoxify aluminium (Al) by producing phytosiderophores, such as chlorogenic acid, citric acid, and malic acid, and localizing Al in cell walls. Root-endophytic Chaetomium cupreum, which produces microbial siderophores, enhances Al tolerance in M. sinensis...

The iBUG Eye Segmentation Dataset

This paper presents the first dataset for eye segmentation in low resolution images. Although eye segmentation has long been a vital preprocessing step in biometric applications, this work is the first to focus on low resolutions image that can be expected from a consumer-grade camera under conventional human-computer interaction and / or video-chat scenarios. Existing eye...

Modelo térmico para estimar la potencia de cocción estándar de cocinas solares

Paper presents of some aspects of thermal physics necessary for the development of small-scale solar cookers by developing a computational semi-empirical thermal model. The free parameters of the models are adjusted with data obtained from an experimental design, which consists of heating a fluid, exposing the cooker to radiation that produces an array of incandescent lamps to...
