TL;DR: The use of Raven's Coloured Progressive Matrices in experiments with brain-damaged patients is briefly reviewed and normative data were calculated on 305 normals.
Abstract: The use of Raven's Coloured Progressive Matrices (PM 47) in experiments with brain-damaged patients is briefly reviewed. Because norms for adults are still not available, normative data were calculated on 305 normals; corrections for age and education and centile allocation of the scores are furnished.

TL;DR: The association between genotype and degree of hearing loss in persons with HI and biallelic GJB2 mutations was assessed and two genotypes had significantly more-severe HI than that of 35delG homozygotes.
Abstract: Hearing impairment (HI) affects 1 in 650 newborns, which makes it the most common congenital sensory impairment. Despite extraordinary genetic heterogeneity, mutations in one gene, GJB2, which encodes the connexin 26 protein and is involved in inner ear homeostasis, are found in up to 50% of patients with autosomal recessive nonsyndromic hearing loss. Because of the high frequency of GJB2 mutations, mutation analysis of this gene is widely available as a diagnostic test. In this study, we assessed the association between genotype and degree of hearing loss in persons with HI and biallelic GJB2 mutations. We performed cross-sectional analyses of GJB2 genotype and audiometric data from 1,531 persons, from 16 different countries, with autosomal recessive, mild-to-profound nonsyndromic HI. The median age of all participants was 8 years; 90% of persons were within the age range of 0-26 years. Of the 83 different mutations identified, 47 were classified as nontruncating, and 36 as truncating. A total of 153 different genotypes were found, of which 56 were homozygous truncating (T/T), 30 were homozygous nontruncating (NT/NT), and 67 were compound heterozygous truncating/nontruncating (T/NT). The degree of HI associated with biallelic truncating mutations was significantly more severe than the HI associated with biallelic nontruncating mutations (P<.0001). The HI of 48 different genotypes was less severe than that of 35delG homozygotes. Several common mutations (M34T, V37I, and L90P) were associated with mild-to-moderate HI (median 25-40 dB). Two genotypes--35delG/R143W (median 105 dB) and 35delG/dela(GJB6-D13S1830) (median 108 dB)--had significantly more-severe HI than that of 35delG homozygotes.

TL;DR: Evidence of ALS being a complex genetic trait with a polygenic architecture is established and the SNP-based heritability is estimated at 8.5%, with a distinct and important role for low-frequency variants (frequency 1–10%).
Abstract: To elucidate the genetic architecture of amyotrophic lateral sclerosis (ALS) and find associated loci, we assembled a custom imputation reference panel from whole-genome-sequenced patients with ALS and matched controls (n = 1,861). Through imputation and mixed-model association analysis in 12,577 cases and 23,475 controls, combined with 2,579 cases and 2,767 controls in an independent replication cohort, we fine-mapped a new risk locus on chromosome 21 and identified C21orf2 as a gene associated with ALS risk. In addition, we identified MOBP and SCFD1 as new associated risk loci. We established evidence of ALS being a complex genetic trait with a polygenic architecture. Furthermore, we estimated the SNP-based heritability at 8.5%, with a distinct and important role for low-frequency variants (frequency 1-10%). This study motivates the interrogation of larger samples with full genome coverage to identify rare causal variants that underpin ALS risk.

TL;DR: The hypothesis that neuroactive steroids might represent a new therapeutic strategy for peripheral neuropathy is proposed.
Abstract: It is now well known that peripheral nerves are a target for the action of neuroactive steroids. This review summarizes observations obtained so far, indicating that through the interaction with classical and nonclassical steroid receptors, neuroactive steroids (e.g., progesterone, testosterone and their derivatives, estrogens, etc.) are able to influence several parameters of the peripheral nervous system, particularly its glial compartment (i.e., Schwann cells). Interestingly, some of these neuroactive steroids might be considered as promising neuroprotective agents. They are able to counteract neurodegenerative events of rat peripheral nerves occurring after experimental physical trauma, during the aging process, or in hereditary demyelinating diseases. On this basis, the hypothesis that neuroactive steroids might represent a new therapeutic strategy for peripheral neuropathy is proposed.

TL;DR: HMG1 has all the hallmarks of a molecule that can promote atherosclerosis and restenosis after vascular damage, and it is shown that HMG1 can be released by damage or necrosis of a variety of cell types, including endothelial cells.
Abstract: HMG1 (high mobility group 1) is a ubiquitous and abundant chromatin component. However, HMG1 can be secreted by activated macrophages and monocytes, and can act as a mediator of inflammation and endotoxic lethality. Here we document a role of extracellular HMG1 in cell migration. HMG1 (and its individual DNA-binding domains) stimulated migration of rat smooth muscle cells in chemotaxis, chemokinesis, and wound healing assays. HMG1 induced rapid and transient changes of cell shape, and actin cytoskeleton reorganization leading to an elongated polarized morphology typical of motile cells. These effects were inhibited by antibodies directed against the receptor of advanced glycation endproducts, indicating that the receptor of advanced glycation endproducts is the receptor mediating the HMG1-dependent migratory responses. Pertussis toxin and the mitogen-activated protein kinase kinase inhibitor PD98059 also blocked HMG1-induced rat smooth muscle cell migration, suggesting that a Gi/o protein and mitogen-activated protein kinases are required for the HMG1 signaling pathway. We also show that HMG1 can be released by damage or necrosis of a variety of cell types, including endothelial cells. Thus, HMG1 has all the hallmarks of a molecule that can promote atherosclerosis and restenosis after vascular damage.
