Density, planning, and the emergent landscapes of purpose-built student accommodation in England
This mini review explores perspectives on density and discretionary planning policy in relation to the emergent landscapes of purpose-built student accommodation (PBSA) across selected English university cities. It examines the nexus between density in planning policies and transformations in student accommodation, presenting a research gap requiring further investigation. Our research builds upon limited literature on UK PBSA within which there has been inadequate interrogation of policy impacts on the substantial growth of this now mature market sector. By better understanding the relations between national planning policies and their local interpretations regarding PBSA, we can move toward improving understandings for urban futures. The intersectionality between the evolution of the PBSA sector and the planning system are currently underexplored. The paper highlights the proliferation, densification, and concentration patterns of PBSAs and their connections to the surrounding planning system. The emergence of privately developed PBSA in the UK is typically characterized by medium to high rise, and medium to high density development. Higher density PBSA has created a dynamic spectrum of impacts reflecting subjective perceptions of their emergence in university cities. Our mini review illustrates the growth trajectory and direction of the PBSA sector. We conclude with a reflection on the discretionary nature of planning policies for density that often create regulatory loopholes allowing PBSA to thrive as a niche real estate asset class but not necessarily as a local and social collective asset
Group IV Phospholipase A2α Controls the Formation of Inter-Cisternal Continuities Involved in Intra-Golgi Transport
The enzyme phospholipase A2 (cPLA2α) is involved in the formation of intercisternal tubules that mediate transport of proteins within the Golgi complex
Retrospective evaluation of whole exome and genome mutation calls in 746 cancer samples
Funder: NCI U24CA211006Abstract: The Cancer Genome Atlas (TCGA) and International Cancer Genome Consortium (ICGC) curated consensus somatic mutation calls using whole exome sequencing (WES) and whole genome sequencing (WGS), respectively. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, which aggregated whole genome sequencing data from 2,658 cancers across 38 tumour types, we compare WES and WGS side-by-side from 746 TCGA samples, finding that ~80% of mutations overlap in covered exonic regions. We estimate that low variant allele fraction (VAF < 15%) and clonal heterogeneity contribute up to 68% of private WGS mutations and 71% of private WES mutations. We observe that ~30% of private WGS mutations trace to mutations identified by a single variant caller in WES consensus efforts. WGS captures both ~50% more variation in exonic regions and un-observed mutations in loci with variable GC-content. Together, our analysis highlights technological divergences between two reproducible somatic variant detection efforts

Building taller, building denser: explorations in placemaking in London
Densification denotes, in some form, the increasing density of people living and working in urban areas. In many cities, higher densities demand constructing taller buildings; and therefore, planners need to address their potential impact on the fabric of our cities (both individually and cumulatively) and the political and economic imperatives for cities to build ever taller. However, many existing policies and regulations are outdated and fail to address the nuances of density and its impact on placemaking. This chapter explores these tensions, focusing on the Vauxhall Nine Elms Battersea Opportunity Area in central London. The master plan for the new neighborhood envisages 25,000 new jobs and 20,000 new homes. At the heart of the master plan is a massive increase in density through building tall buildings across the area. The authors explore this development and examine whether the densification and building height approach is an effective placemaking strategy. The stated claims for higher density and taller buildings create place through urban planning and design approaches and processes

Omega3 Supplementation and Intermittent Hypobaric Hypoxia Induce Cardioprotection Enhancing Antioxidant Mechanisms in Adult Rats
Artículo de publicación ISIIntermittent hypobaric hypoxia (IH) is linked with oxidative stress, impairing
cardiac function. However, early IH also activate cardio-protective mechanisms. Omega 3
fatty acids (Ω3) induce cardioprotection by reducing infarct size and reinforcing antioxidant
defenses. The aim of this work was to determine the combined effects of IH and Ω3 on
cardiac function; oxidative balance and inflammatory state. Twenty-eight rats were randomly
divided into four groups: normobaric normoxia (N); N + Ω3 (0.3 g·kg−1·day−1); IH; and
IH + Ω3. IH was induced by 4 intercalate periods of hypoxia (4 days)—normoxia (4 days)
in a hypobaric chamber during 32 days. At the end of the exposure, hearts were mounted in
a Langendorff system and subjected to 30 min of ischemia followed by 120 min of
reperfusion. In addition, we determined HIF-1α and ATP levels, as well as oxidative stress
by malondialdehyde and nitrotyrosine quantification. Further, the expression of the
antioxidant enzymes superoxide dismutase, catalase, and glutathione peroxidase was
determined. NF-kappaB and myeloperoxidase levels were assessed in the hearts. Relative to N hearts, IH improved left ventricular function (Left ventricular developed pressure: N;
21.8 ± 3.4 vs. IH; 42.8 ± 7.1 mmHg; p < 0.05); reduced oxidative stress (Malondialdehyde:
N; 14.4 ± 1.8 vs. IH; 7.3 ± 2.1 μmol/mg prot.; p < 0.05); and increased antioxidant enzymes
expression. Supplementation with Ω3 induces similar responses as IH group. Our findings
suggest that both, IH and Ω3 in an independent manner, induce functional improvement by
antioxidant and anti-inflammatory mechanisms, establishing cardio-protectionFONDECYT grants 11110426, 1110595 and
