HIV-1 superinfection with a triple-class drug-resistant strain in a patient successfully controlled with antiretroviral treatment.

We report a case of HIV-1 superinfection (HSI) with a clade B, triple-class resistant virus in a patient successfully controlling viremia with continuous combination antiretroviral therapy started 8 years earlier during primary HIV infection. The course of HIV infection prior to HSI was monitored in both the source partner and recipient (8 and 11 years, respectively) and 4 years following HSI. This case report demonstrates re-infection with HIV-1 despite effective combination antiretroviral therapy.

Características estratigráficas y sedimentológicas del 'Garumniense' en el sector de Ager (Pre-Pirineo, Lleida).

La sucesión estratigráfica de los depósitos continentales de la ' cuenca de Ager corresponde a sedimentos lacustres (Fm Massana), depósitos fluviales y de llanura de inundación (Fm. Figuerola), sedimentos lacustres (Fm. Milla) y una sucesión de materiales palustres, lacustres, fluviales, de lagunas evaponticas y aun mareales (Complejo de Perauba). Todos esos materiales fueron depositados en los diferentes medios sedimentarios citados que se desarrollaron en esa zona entre el Maastrichtiense y el Paleógeno inferior. En concreto, el tránsito entre el Cretácico y el Terciario (m)se produjo en uno de esos medios sedimentarios. Anteriormente se habia correlacionado ese límite con un nivel litoestratigráfico concreto (carbonatos de la Fm. Milla), pero actualmente se conoce que ese evento se produce en el tercio superior de la unidad tem'gena de la Fm. Figuerola. Los datos de paleomagnetismo sugieren que los dinosaunos y las carófitas cretácicas empezaron a desaparacer, en esta zona, unos dos millones de años antes que sucediera el evento asociado al límite K/T.

Pre-pregnancy and pregnancy predictors of obesity.

Obesity has progressively become a global epidemic that constitutes one of the biggest current health problems worldwide. Pregnancy is a risk factor for excessive weight gain. Factors that may predict development of obesity in later life mainly include gestational weight gain, pre-pregnancy nutritional status, age, parity and race. Change in lifestyle factors, such as eating habits, enrollment in physical activity, smoking and duration of lactation, in addition to the above factors, may also contribute to the development of obesity but are still not fully understood. Women who retain more body weight after pregnancy have, in general, larger pregnancy body weight gain, higher pre-pregnancy body mass index, marked weight changes in previous pregnancies, lactate slightly less and stop smoking during pregnancy to a larger extent. In addition, irregular eating habits and decreased leisure time activity after delivery influence postpartum weight retention. Taking into consideration the epidemic of obesity, with all its adverse long-term consequences, there is an increasing need to promote counseling before, during and after pregnancy on the role of diet and physical activity in reproductive health.

Identification of opsA, a gene involved in solute stress mitigation and survival in soil, in the polycyclic aromatic hydrocarbon-degrading bacterium Novosphingobium sp. strain LH128.

The aim of this study was to identify genes involved in solute and matric stress mitigation in the polycyclic aromatic hydrocarbon (PAH)-degrading Novosphingobium sp. strain LH128. The genes were identified using plasposon mutagenesis and by selection of mutants that showed impaired growth in a medium containing 450 mM NaCl as a solute stress or 10% (wt/vol) polyethylene glycol (PEG) 6000 as a matric stress. Eleven and 14 mutants showed growth impairment when exposed to solute and matric stresses, respectively. The disrupted sequences were mapped on a draft genome sequence of strain LH128, and the corresponding gene functions were predicted. None of them were shared between solute and matric stress-impacted mutants. One NaCl-affected mutant (i.e., NA7E1) with a disruption in a gene encoding a putative outer membrane protein (OpsA) was susceptible to lower NaCl concentrations than the other mutants. The growth of NA7E1 was impacted by other ions and nonionic solutes and by sodium dodecyl sulfate (SDS), suggesting that opsA is involved in osmotic stress mitigation and/or outer membrane stability in strain LH128. NA7E1 was also the only mutant that showed reduced growth and less-efficient phenanthrene degradation in soil compared to the wild type. Moreover, the survival of NA7E1 in soil decreased significantly when the moisture content was decreased but was unaffected when soluble solutes from sandy soil were removed by washing. opsA appears to be important for the survival of strain LH128 in soil, especially in the case of reduced moisture content, probably by mitigating the effects of solute stress and retaining membrane stability.

The Reliability of Pre-travel History to Decide on Appropriate Counseling and Vaccinations: A Prospective Study.

BACKGROUND: Although medical and travel plans gathered from pre-travel interviews are used to decide the provision of specific pre-travel health advice and vaccinations, there has been no evaluation of the relevance of this strategy. In a prospective study, we assessed the agreement between pre-travel plans and post-travel history and the effect on advice regarding the administration of vaccines and recommendations for malaria prevention. METHODS: We included prospectively all consenting adults who had not planned an organized tour. Pre- and post-travel information included questions on destination, itineraries, departure and return dates, access to bottled water, plan of bicycle ride, stays in a rural zone, and close contact with animals. The outcomes measured included: agreement between pre- and post-travel itineraries and activities; and the effect of these differences on pre-travel health recommendations, had the traveler gone to the actual versus intended destinations for actual versus intended duration and activities. RESULTS: Three hundred and sixty-five travelers were included in the survey, where 188 (52%) were males (median age 38 years). In 81(23%) travelers, there was no difference between pre- and post-travel history. Disagreement between pre- and post-travel history were the highest for stays in rural zones or with local people (66% of travelers), close contact with animals (33%), and bicycle riding (21%). According to post-travel history, 125 (35%) travelers would have needed rabies vaccine and 9 (3%) typhoid fever vaccine. Potential overprovision of vaccine was found in <2% of travelers. A change in the malaria prescription would have been recommended in 18 (5%) travelers. CONCLUSIONS: Pre-travel history does not adequately reflect what travelers do. However, difference between recommendations for the actual versus intended travel plans was only clinically significant for the need for rabies vaccine. Particular attention during pre-travel health counseling should focus on the risk of rabies, the need to avoid close contact with animals and to seek care for post-exposure prophylaxis following an animal bite.

Sequence analysis and expression of the attachment and fusion proteins of canine distemper virus wild-type strain A75/17.

The biological properties of wild-type A75/17 and cell culture-adapted Onderstepoort canine distemper virus differ markedly. To learn more about the molecular basis for these differences, we have isolated and sequenced the protein-coding regions of the attachment and fusion proteins of wild-type canine distemper virus strain A75/17. In the attachment protein, a total of 57 amino acid differences were observed between the Onderstepoort strain and strain A75/17, and these were distributed evenly over the entire protein. Interestingly, the attachment protein of strain A75/17 contained an extension of three amino acids at the C terminus. Expression studies showed that the attachment protein of strain A75/17 had a higher apparent molecular mass than the attachment protein of the Onderstepoort strain, in both the presence and absence of tunicamycin. In the fusion protein, 60 amino acid differences were observed between the two strains, of which 44 were clustered in the much smaller F2 portion of the molecule. Significantly, the AUG that has been proposed as a translation initiation codon in the Onderstepoort strain is an AUA codon in strain A75/17. Detailed mutation analyses showed that both the first and second AUGs of strain A75/17 are the major translation initiation sites of the fusion protein. Similar analyses demonstrated that, also in the Onderstepoort strain, the first two AUGs are the translation initiation codons which contribute most to the generation of precursor molecules yielding the mature form of the fusion protein.

Improvement of a testing apparatus for dynamometry: procedures for penetrometry and influence of strain rate to quantify the tensile strength of soil aggregates

Soil penetration resistance (PR) and the tensile strength of aggregates (TS) are commonly used to characterize the physical and structural conditions of agricultural soils. This study aimed to assess the functionality of a dynamometry apparatus by linear speed and position control automation of its mobile base to measure PR and TS. The proposed equipment was used for PR measurement in undisturbed samples of a clayey "Nitossolo Vermelho eutroférrico" (Kandiudalfic Eutrudox) under rubber trees sampled in two positions (within and between rows). These samples were also used to measure the volumetric soil water content and bulk density, and determine the soil resistance to penetration curve (SRPC). The TS was measured in a sandy loam "Latossolo Vermelho distrófico" (LVd) - Typic Haplustox - and in a very clayey "Nitossolo Vermelho distroférrico" (NVdf) - Typic Paleudalf - under different uses: LVd under "annual crops" and "native forest", NVdf under "annual crops" and "eucalyptus plantation" (> 30 years old). To measure TS, different strain rates were applied using two dynamometry testing devices: a reference machine (0.03 mm s-1), which has been widely used in other studies, and the proposed equipment (1.55 mm s-1). The determination coefficient values of the SRPC were high (R² > 0.9), regardless of the sampling position. Mean TS values in LVd and NVdf obtained with the proposed equipment did not differ (p > 0.05) from those of the reference testing apparatus, regardless of land use and soil type. Results indicate that PR and TS can be measured faster and accurately by the proposed procedure.
