BACKGROUND Poor retention in HIV care of mother-baby pairs remains a public health challenge in the elimination of mother-to-child transmission (eMTCT) of HIV. We determined the rate of non-retention and time to non-retention of mother-baby pairs and associated factors in Gulu district, Northern Uganda. METHODS Mother-baby pairs enrolled into the eMTCT programme at Gulu Regional Referral Hosp...

BACKGROUND Gastrointestinal (GI) complications are common in hereditary transthyretin amyloidosis and an autonomic dysfunction has been considered to explain these symptoms. The aim of this study was to investigate the impact of autonomic neuropathy on gastric emptying in hereditary transthyretin amyloidosis and to relate these findings to nutritional status, GI symptoms, gender, and age at dis...

The investigations were made in a loop bioreactor, where biomass was immobilized in the ceramic carrier. The influence of the internal circulation rate on the biodegradation efficiency of brewery wastes by immobilized biomass and on production of surplus sludge was examined. The rates of the internal circulation were 12, 38, 50 dm·h. The experiments were performed at constant loading rate of th...

OBJECTIVE We aimed at summarising rates and factors associated with retention in HIV care prior to antiretroviral treatment (ART) eligibility in sub-Saharan Africa. DESIGN We conducted a systematic literature review (2002-2014). We searched Medline/Pubmed, Scopus and Web of Science, as well as proceedings of conferences. We included all original research studies published in peer-reviewed jou...

The effect of the modifier concentration and flow rate on the chromatographic performance of a second generation Chromolith® RP-18e column, under isocratic and gradient elution with acetonitrile-water mixtures, was examined using four sulphonamides as probe compounds. The acetonitrile concentration was varied between 5 and 55% (v/v), and the flow rate between 0.1 and 5.0 mL/min, keeping the oth...

Effects of 1-aminoethoxyvinylglycine hydrochloride (AVG or Aviglycine HCl or ReTain) and α-naphthalene acetic acid (NAA) on fruit retention, fruit quality, eveloved ethylene, and respiration in ‘Rome Beauty’ and three ‘Delicious’ apple cultivars (Malus domestica Borkh.) were studied.  The experimental trees were treated with either AVG, applied at 120 g a.i. per 935 L. ha-1 or NAA, applied at t...

The retention (binding to or association with the plant) of Escherichia coli by cut leaves and fruits after vigorous water washing was compared with that by sprouts. Retention by fruits and leaves was similar but differed from retention by sprouts in rate, effect of wounding and requirement for poly-β,1-6-N-acetyl-D-glucosamine. Escherichia coli was retained by cut ends of lettuce leaves within...

Intensive forest management led to elevated losses of nitrogen from a recently harvested loblolly pine plantation in North Carolina. Measurements of nitrogen-15 retention in the field demonstrated that microbial uptake of nitrogen during the decomposition of residual organic material was the most important process retaining nitrogen. Management practices that remove this material cause increase...
