Etiology of Persistent Microalbuminuria in Nigeria (P_MICRO study): Protocol and study design
BACKGROUND: Microalbuminuria is an independent risk factor for cardiovascular and kidney disease and a predictor of end organ damage, both in the general population and in persons with HIV (PWH). Microalbuminuria is also an important risk factor for mortality in PWH treated with antiretroviral therapy (ART). In the ongoing Renal Risk Reduction (R3) study in Nigeria, we identified a high prevalence of microalbuminuria confirmed by two measurements 4-8 weeks apart in ART-experienced, virologically suppressed PWH. Although Stage 1 or 2 hypertension and exposure to potentially nephrotoxic antiretroviral medications were common in R3 participants, other traditional risk factors for albuminuria and kidney disease, including diabetes, APOL1 high-risk genotype, and smoking were rare. Co-infection with endemic pathogens may also be significant contributors to albuminuria, but co-infections were not evaluated in the R3 study population.
METHODS: In Aim 1, we will cross-sectionally compare the prevalence of albuminuria and established kidney disease risk factors in a cohort of PWH to age- and sex-matched HIV-negative adults presenting for routine care at the Aminu Kano Teaching Hospital in Kano, Nigeria. We will leverage stored specimens from 2500 R3 participants and enroll an additional 500 PLWH recently initiated on ART (≤ 24 months) and 750 age- and sex-matched HIV-negative adults to determine the contribution of HIV, hypertension, and other comorbid medical conditions to prevalent albuminuria. In Aim 2, we will follow a cohort of 1000 HIV-positive, ART-treated and 500 HIV-negative normoalbuminuric adults for 30 months to evaluate the incidence and predictors of albuminuria.
DISCUSSION: The findings from this study will support the development of interventions to prevent or address microalbuminuria in PWH to reduce kidney and cardiovascular morbidity and mortality. Such interventions might include more intensive monitoring and treatment of traditional risk factors, the provision of renin-angiotensin aldosterone system or sodium-glucose cotransporter-2 inhibitors, consideration of changes in ART regimen, and screening and treatment for relevant co-infections

Zooplankton abundance in relation to state and type of intrusions onto the southeastern United States shelf during summer
The vertical distribution of zooplankton on the continental shelf of northeastern Florida was determined in and around upwelling events and related to concentrations of particulate matter. Doliolida and the cladoceran Penilia avirostris were significantly more abundant in upwelled water \u3c22°C and the cyclopoid genus Oncaea more abundant at warmer temperatures. The abundance of doliolida, Oithona and Oncaea in intrusions and the thermocline was significantly higher in older than in recently upwelled waters. The vertical sequences of the abundance of zooplankton and particulate matter (2-114 μm ESD) were identical. Zooplankton maxima co-occurred primarily with maxima in phytoplankton biomass (chlorophyll a) and only partly with primary productivity

Plant communities in the old-growth forests of North Coastal Oregon
This study was conducted in the old-growth forests of Clatsop,
Tillamook, and Lincoln counties, Oregon. The three objectives of
the research were to describe and classify the near-climax plant
communities found within the forests, to relate the associes described
by a previous study to the forest communities characterized by the
present study, and to relate the present elk distribution to the distribution
of plant communities identified.
Vegetation, soils, and physiographic data were collected from
a large number of timbered stands of variable sizes scattered throughout
the area bounded on the north by Youngs River and on the south
by the Siletz River. Sampling was stratified within each tract to
obtain homogeneous vegetation-soil sampling locations. Vegetation
data, recorded from 137 locations, formed the basis for the plant
community classification. Society tables were used for a
phytosociological synthesis of vegetation data.
Eleven plant communities were identified within the timbered
areas studied. All were within what might be termed a broad Tsuga
heterophylla forest association. Plant species useful for identifying
community stands were used in naming the eleven plant communities:
Tsuga heterophylla-Picea sitchensis/Oplopanax horridum/
Athyrium filix-femina
Tsuga heterophylla-Picea sitchensis/Gaultheria shallon/
Blechnum spiCant
Tsuga heterophylla-Abies amabilis/Gaultheria shallon/
Tiarella unifoliata
Tsuga heterophylla-Abies amabilis/Vaccinium ovalifolium/
Oxalis oregana
Tsuga heterophylla-Abies amabilis /Rhododendron macrophyllum/
Cornus canadensis
Tsuga heterophylla- Vaccinium ovalifolium/Polystichum
munitum
Tsuga heterophylla/Acer circinatum/Cryptogramma crispa
Tsuga heterophylla/Berberis nervosa/ Trientalis latifolia
Tsuga heterophylla/Polystichum munitum-Adiantum pedatum
Tsuga heterophylla/Vaccinium membranaceum/Xerophyllum
tenax
Tsuga heterophylla-Abies procera/Vaccinium membranaceum/
Cryptogramma crispa
A dichotomous key was prepared to facilitate the identification
of community stands in the field. Field tests in new locations were
not conducted to determine the accuracy of the key, but data from individual stands were used to key locations into the proper community
without difficulty.
Stands of associes previously described on logged and burned
forest lands are compared with those of the near-climax plant communities
identified.
The present elk distribution of the area is related to a north to
south geographic change in the amount of "coastal-habitat". The relative
importance of communities to deer and elk is compared. Suggestions
are made for the utility of the phytosociological classification
of this important forested area

GammeV: A gamma to milli-eV particle search at Fermilab
GammeV is an experiment conducted at Fermilab that employs the light shining through a wall technique to search for axion-like particles and employs a particle in a jar technique to search for dilaton-like chameleon particles. We obtain limits on the coupling of photons to an axion-like particle that extend previous limits for both scalars and pseudoscalars in the milli-eV mass range. We are able to exclude the axion-like particle interpretation of the anomalous PVLAS 2006 result by more than 5 standard deviations. We also present results on a search for chameleons and set limits on their possible coupling to photons
