Barbosa J, Silva Á, Ferreira MA, Severo M.
PMID: 28425883
Acta Med Port. 2016 Dec 30;29(12):803-808. doi: 10.20344/amp.8350. Epub 2016 Dec 30.

INTRODUCTION: The transition from secondary to higher education is a challenging and demanding period for medical students. The ability to manage study time effectively and to be a self-regulated learner is essential to cope with the exponential growth of...

Haematological malignancies and acute kidney injury requiring nephrology consultation: challenging the worst of the worst.

Clinical kidney journal

Chuva T, Maximino J, Barbosa J, Silva S, Paiva A, Baldaia J, Loureiro A.
PMID: 27274827
Clin Kidney J. 2016 Jun;9(3):418-23. doi: 10.1093/ckj/sfw026. Epub 2016 May 04.

BACKGROUND: Acute kidney injury (AKI) often complicates the course of haematological malignancies (HMs) and confers a worse prognosis. The majority of these patients are managed by the attending physician, yet, a small group, mostly coincident with the worst presentation...

Int Arch Med. 2014 May 12;7:24. doi: 10.1186/1755-7682-7-24. eCollection 2014.

BACKGROUND: Urinary incontinence (UI) is defined as any involuntary loss of urine that can influence the quality of life, personal hygiene and social interaction. The types of UI that most affect women are stress urinary incontinence, urge incontinence and...

Patchy Traction Alopecia Mimicking Areata.

International journal of trichology

Barbosa AB, Donati A, Valente NS, Romiti R.
PMID: 26903751
Int J Trichology. 2015 Oct-Dec;7(4):184-6. doi: 10.4103/0974-7753.171588.

Acute traction alopecia is a diagnostic challenge when the external factor is not suspected or admitted. We report two female patients with non-scarring patchy alopecia resulting from traction of video-electroencephalogram electrodes in which the clinical diagnosis of alopecia areata...

Microsatellite markers for Senna spectabilis var. excelsa (Caesalpinioideae, Fabaceae).

Applications in plant sciences

López-Roberts MC, Barbosa AR, Paganucci de Queiroz L, van den Berg C.
PMID: 26819856
Appl Plant Sci. 2016 Jan 11;4(1). doi: 10.3732/apps.1500062. eCollection 2016 Jan.

PREMISE OF THE STUDY: Senna spectabilis var. excelsa (Fabaceae) is a South and Central American tree of great ecological importance and one of the most common species in several sites of seasonally dry forests. Our goal was to develop...

Microalgal triacylglycerides production in outdoor batch-operated tubular PBRs.

Biotechnology for biofuels

Benvenuti G, Bosma R, Klok AJ, Ji F, Lamers PP, Barbosa MJ, Wijffels RH.
PMID: 26175799
Biotechnol Biofuels. 2015 Jul 15;8:100. doi: 10.1186/s13068-015-0283-2. eCollection 2015.

BACKGROUND: Microalgal triacylglycerides (TAGs) are a promising sustainable feedstock for the biofuel, chemical and food industry. However, industrial production of microalgal products for commodity markets is not yet economically viable, largely because of low microalgal productivity. The latter is...

The effects of aeration and veratryl alcohol on the production of two laccases by the ascomycete Botryosphaeria sp.

Enzyme and microbial technology

Dekker RF, Barbosa AM.
PMID: 11118601
Enzyme Microb Technol. 2001 Jan 02;28(1):81-88. doi: 10.1016/s0141-0229(00)00274-x.

The ascomycete, Botryosphaeria sp, produced two extracellular constitutive laccases (PPO-I and PPO-II) active toward the substrates: 2, 2(1)-azino-bis(3-ethyl-benzthiazoline-6-sulfonic acid) [ABTS], and 2,6-dimethoxyphenol (DMP), respectively. The production of both laccases increased when the fungal isolate was grown in the presence...

Highway runoff and potential for removal of heavy metals in an infiltration pond in Portugal.

The Science of the total environment

Barbosa AE, Hvitved-Jacobsen T.
PMID: 10535116
Sci Total Environ. 1999 Sep 01;235(1):151-9. doi: 10.1016/s0048-9697(99)00208-9.

Highway runoff from IP 4, a mountain road in the north-east of Portugal, has been monitored using a system integrating a raingauge, a flowmeter and an automatic water sampler. Average daily traffic (ADT) is 6000 and the study catchment...

A comparative study of some hydroxyanthraquinones as acid-base indicators.

Talanta

Barbosa J, Bosch E, Carrera R.
PMID: 18963955

Alizarin, Alizarin S, quinizarin and quinalizarin have been compared as acid-base indicators with Bromocresol Green and Methyl Orange as reference indicators. The chromaticity co-ordinates, complementary chromaticity co-ordinates, pK(a) values, transition pH-range, pH of maximum colour change, optimum concentration for...

Study of 1,4-dihydroxyanthraquinone as an acid-base indicator in isopropyl alcohol medium Evaluation of colour-change limits through complementary chromaticity parameters.

PMID: 18963587
Talanta. 1984 Apr;31(4):279-82. doi: 10.1016/0039-9140(84)80277-5.

The use of 1,4-dihydroxyanthraquinone as an acid-base indicator in isopropyl alcohol medium is proposed. The acid dissociation constants of the indicator in isopropyl alcohol solution are pK(a1) = 12.95 +/- 0.03 and pK(a2) = 15.96 +/- 0.07. The sharpness...

Equilibrium constants and assay of bases in acetonitrile.

Talanta
