Objective: To characterize the evolution of central nervous system (CNS) inflammation in HIV-1 infection applying a panel of cerebrospinal fluid (CSF) inflammatory biomarkers to grouped subjects representing a broad spectrum of systemic HIV-1 immune suppression, CNS injury and viral control. Methods: This is a cross-sectional analysis of archived CSF and blood samples, assessing concentrations of 10 functionally diverse soluble inflammatory biomarkers by immunoassays in 143 HIV-1-infected subjects divided into 8 groups: untreated primary HIV-1 infection...

Large oaks Quercus robur have increased at Tumhem's oak meadow

Hans Alexandersson
We have described a significant increase in the number of large oaks Quercus robur in the Tunhem oak meadow during 23 years. We define large oak as having a circumference at chest height larger than 250 centimeters. The number of large oaks have increased by 29 percent from our first survey in 1996 to our second survey in 2019. Most of the recruitment of larger oaks are in the smaller size-classes from 250 to 400...

Molecular phylogenetics of the palm tribe Lepidocaryeae (Calamoideae: Arecaceae) and description of a new species of Mauritiella

Maria Fernanda Torres Jimenez
English: The palm tribe Lepidocaryeae (Arecaceae) comprises seven genera and 51 currently accepted species that are distributed in lowland tropical forests and savannas across Africa and the Americas. Subtribal relationships within Lepidocaryeae have been a persistent challenge, limiting our understanding of its systematics, morphology, and biogeography. Several aspects make the tribe an ideal system to study plant evolution and diversity: it is well-represented in the fossil record as a prolific pollen producer, its continental diversity...

Phylogenetic analysis of HIV-1 shows frequent cross-country transmission and local population expansions

Marc Bennedbæk, Anna Zhukova, Man-Hung Eric Tang, Jaclyn Bennet, Paula Munderi, Kiat Ruxrungtham, Magnus Gisslen, Michael Worobey, Jens D Lundgren & Rasmus L Marvig
Understanding of pandemics depends on characterization of pathogen collections from well-defined and demographically diverse cohorts. Since its emergence in Congo almost a century ago, HIV-1 has geographically spread and genetically diversified into distinct viral subtypes. Phylogenetic analysis can be used to reconstruct the ancestry of the virus to inform on the origin and distribution of subtypes. We sequenced two 3.6 kb amplicons of HIV-1 genomes from 3,197 participants in a clinical trial with consistent and...

Prenatal androgen exposure causes a sexually dimorphic transgenerational increase in offspring susceptibility to anxiety disorders

Elisabet Stener-Victorin, Sanjiv Risal, Maria Manti, Haojiang Lu, Romina Fornes, Henrik Larsson, Anna Benrick, Qiaolin Deng, Mina A. Rosenqvist & Carolyn E. Cesta
If and how obesity and elevated androgens in women with polycystic ovary syndrome (PCOS) affect their offspring’s psychiatric health is unclear. Using data from Swedish population health registers, we showed that daughters of mothers with PCOS have a 78% increased risk of being diagnosed with anxiety disorders. We next generated a PCOS-like mouse (F0) model induced by androgen exposure during late gestation, with or without diet-induced maternal obesity, and showed that the first generation (F1)...

Chain length, growth rate and clearance rate of Thalassiosira Rotula, Chaetoceros Curvisetus, and Chaetoceros Affinis when exposed to copepodamides.

Kristie Rigby & Erik Selander
Colony formation is common feature among non-motile marine phytoplankton. Several theories exist around the potential benefits of larger colonies. Here we test the hypothesis that predation is one of the drivers behind colony formation and chain length plasticity. We exposed cultures of Thalassiosira rotula, Chaetoceros curvisetus and Chaetoceros affinis to copepodamides, a chemical alarm cue released by copepods and perceived as an indicator of predation threat by their prey. This was coupled with a grazing...

How biases in sperm storage relate to sperm use during oviposition in female yellow dung flies

Marco Demont, Paul Ward, Wolf Blanckenhorn, Stefan Lüpold, Oliver Martin & Luc Bussière
Precise mechanisms underlying sperm storage and utilization are largely unknown, and data directly linking stored sperm to paternity remain scarce. We used competitive microsatellite PCR to study the effects of female morphology, copula duration and oviposition on the proportion of stored sperm provided by the second of two copulating males (S2) in Scathophaga stercoraria (Diptera: Scathophagidae), the classic model for sperm competition studies. We genotyped all offspring from potentially mixed-paternity clutches to establish the relationship...

Exercise training has morph-specific effects on telomere, body condition and growth dynamics in a color-polymorphic lizard

Christopher Friesen, Wilson Wilson, Nicky Rollings, Joanna Sudyka, Mathieu Giraudeau, Camilla Whittington & Mats Olsson
Alternative reproductive tactics (ARTs) are correlated suites of sexually selected traits that are likely to impose differential physiological costs on different individuals. While moderate activity might be beneficial, animals living in the wild often work at the margins of their resources and performance limits. Individuals using ARTs may have divergent capacities for activity. When pushed beyond their respective capacities, they may experience condition loss, oxidative stress, and molecular damage that must be repaired with limited...

Data from: The Sulawesi Thrush (Cataponera turdoides; Aves: Passeriformes) belongs to the genus Turdus

Andrew Hart Reeve, Mozes P. K. Blom, Petter Zahl Marki, Romina Batista, Urban Olsson, Veronica Nyström Edmark, Martin Irestedt & Knud Andreas Jønsson
The Asian and Australo-Papuan faunas meet and intermix across the islands of Wallacea. Untangling the origins and relationships of the species inhabiting these archipelagos is an ongoing project that has lasted for well over a century. In recent years, molecular phylogenetic studies have made considerable progress in clarifying the affinities of enigmatic Wallacean taxa; but taxonomic riddles remain, even in groups as well studied as birds. Such is the case with Sulawesi Thrush Cataponera turdoides,...
