Abstract Chromosomal inversions contribute to adaptive speciation by linking co-adapted alleles. Querying 1,375 genomes of the species-rich Malawi cichlid fish radiation, we discovered five large segregating in benthic subradiation that each suppress recombination over more than half a chromosome. Two were transferred from deepwater pelagic Diplotaxodon via admixture, while others established early deep clade. Introgression haplotypes lineages inside and outside radiation coincided with...
The microbiome of Greenland Ice Sheet supraglacial habitats is still underinvestigated, and as a result there lack representative genomes from these environments. In this study, we investigated the through combination culturing-dependent -independent approaches. We explored ice, cryoconite, biofilm, snow biodiversity to answer: (1) how microbial diversity differs between habitats, (2) if obtained bacterial reflect dominant community members, (3) culturing versus high throughput sequencing...

In this paper we describe the main features of size-abundance distribution and taxonomic structure plankton in an oligotrophic, high mountain lake (La Caldera, Sierra Nevada, Spain). The is characterized by a discontinuity size range between ˜2000 32 000 μm 3 (cell volume). Phytoplankton are numerically dominated cyanobacteria Cyanarcus sp., followed chrysophyte Chromulina nevadensis diatom Cyclotella ocellata . Some microplanktonic species such as Navicula radiosa were observed...
A 29-year-old man presented a 2-week history of right popliteal fossa and leg swelling following an arthroscopic meniscectomy. Roentgenographic evaluation showed arterial venous aneurysm at the level, with associated arteriovenous fistula. Popliteal in young men is very rare generally related to open surgical techniques; incidence techniques extremely infrequent.
Permafrost soils store a substantial part of the global soil carbon and nitrogen. However, warming causes abrupt erosion gradual thaw, which make these stocks vulnerable to microbial decomposition into greenhouse gases. Here, we investigated response in situ permafrost thaw. We sequenced total RNA 1 m deep core consisting up 26 500-year-old material from an active site. analysed community layer soil, recently thawed, intact permafrost, found maximum RNA:DNA ratios thawed indicating high...
A 28-year-old man was admitted to our hospital due intermittent dysphagia and repetitive episodes of food impaction. No relevant previous clinical history referred. Physical examination within normal limits.
A 68-year-old man with stage IV renal cell adenocarcinoma was admitted for severe lower gastrointestinal bleeding and hemodynamic instability. After blood transfusion, colonoscopy revealed fresh in the rectum sigmoid colon but no apparent lesions. At 4 days after admission, patient experienced another episode of bleeding. repeat showed active pulsatile from an exposed vessel without mucosal ulceration, consistent a Dieulafoy lesion located 3 cm above anal verge. An endoscopically...
The Greenland Ice Sheet is a biome which mainly microbially driven. Several different niches can be found within the glacial for those microbes able to withstand harsh conditions, e.g., low temperatures, nutrient high UV radiation in summer, and contrasting long dark winters. Eukaryotic algae form blooms during summer on ice surface, interacting with communities of bacteria, fungi, viruses. Cryoconite holes snow are also habitats their own microbial community. Nevertheless, microbiome...

The Greenland Ice Sheet is a biome primarily driven by microbial activity. Despite the harsh conditions, such as cold temperatures, low nutrient levels, high UV radiation in summer, and long dark winters, various niches can be found on ice sheet that support organisms capable of withstanding these challenges. During eukaryotic glacier algae grow large quantities surface, accompanied community bacteria, fungi, viruses. Additionally, cryoconite holes snow serve habitats with their own distinct...
Individual hairs grow from follicles which go through a cycle of different stages. During ‘anagen’ the hair is actively growing, in ‘catagen’ follicle shrinks, while ‘telogen’ resting phase when sheds before next anagen. Abnormal growth usually reflects an abnormal cycle. For example, failure to re‐enter anagen telogen, or short duration anagen, cause poor growth, excessive switching telogen back causes hair. If we could understand what controls these stages, it might be possible develop...
