Copy number variants (CNVs), characterized in recent years by cutting-edge technology, add complexity to our knowledge of the human genome. CNVs contribute not only to human diversity but also to different kinds of diseases including neurodevelopmental delay, autism spectrum disorder and neuropsychiatric diseases. Interestingly, many pathogenic CNVs are shared among these diseases. Studies suggest that pathophysiology of disease may not be simply attributed to a single driver gene within a CNV but also that multifactorial effects may be important...

PURPOSE: In the United States and other countries of the world , high prevalence of pre-pregnancy depressive symptoms and depression during pregnancy is an important public health concern, as they are associated with low birth weight (LBW) and preterm birth (PTB) outcomes in adulthood. However, the relationships among pre-pregnancy depressive symptoms, low birth weight, preterm birth outcomes and household characteristics have not been well established. METHODS: The study used data from 7120 adolescent female participants in the National Longitudinal Study of Adolescent to Adult Health data from Waves I (1994-1995 in-school interview), II (1996 as in-home), III (2001-2002 as in-home interview), IV (2008 as in-home interview) and Wave V is currently underway...

Serum mast cell tryptase is used to support the diagnosis of anaphylaxis. The recommended clinical cut-off for total tryptase (<11.4μg/L) appears unsuitable in the post mortem setting due to largely unknown processes which result in significantly elevated levels in these samples. Consequently there is no widely accepted tryptase cut-off level for diagnosing an anaphylactic death. This 5-year retrospective study compared total tryptase levels in post mortem femoral blood in anaphylactic deaths and control...

Cathepsin L (CTSL) is a lysosomal cysteine protease overexpressed and secreted by tumor cells. Our previous study found that CTSL was involved in ionizing radiation (IR)-induced epithelial-mesenchymal transition (EMT) and the increase of glioma invasion and migration. However, the mechanisms by which CTSL promoted this IR-induced glioma migration and invasion remained unclear. In this study, we demonstrated that IR reduced glycogen synthase kinase-3β (GSK-3β) activity, via the CTSL-mediated phosphorylation of its serine-9 residue, in U251 cells...

Mastitis is a disease of major economic importance to the dairy cattle sector because of the high incidence of clinical mastitis and prevalence of subclinical mastitis and, consequently, the costs associated with treatment, production losses, and reduced animal welfare. Disease-recording systems compiling data from a large number of farms are still not widely implemented around the world; thus, selection for mastitis resistance is often based on genetically correlated indicator traits such as somatic cell count (SCC), udder depth, and fore udder attachment...

When excited over a periodic metamaterial lattice of gold nanoparticles (~ 100nm), localized plasmon resonances (LPR) can be coupled by a diffraction wave propagating along the array plane, which leads to a drastic narrowing of plasmon resonance lineshapes (down to a few nm full-width-at-half-maximum) and the generation of singularities of phase of reflected light. These phenomena look very promising for the improvement of performance of plasmonic biosensors, but conditions of implementation of such diffractively coupled plasmonic resonances, also referred to as plasmonic surface lattice resonances (PSLR), are not always compatible with biosensing arrangement implying the placement of the nanoparticles between a glass substrate and a sample medium (air, water)...

BACKGROUND: Sorafenib (SFN) is an anti-angiogenic chemotherapeutic that prolongs survival of patients with hepatocellular carcinoma (HCC); its side effects, including vascular damages such as hand-foot syndrome (HFS), are a major cause of therapy discontinuation. We previously reported that maintenance of peripheral blood flow by intake of dried bonito broth (DBB) significantly prevented HFS and prolonged the administration period. The amino acids contained in DBB probably contribute to its effects, but the mechanism has not been clarified...

The lithic assemblages at the Oldowan-Acheulean transition in Bed II of Olduvai Gorge, Tanzania, represent a wide variety of raw materials reflecting both the diversity of volcanic, metamorphic, and sedimentary source materials available in the Olduvai basin and surroundings and the preferences of the tool-makers. A geochemical and petrographic systematic analysis of lava-derived archaeological stone tools, combined with textural and mineralogical characterization of quartzite, chert, and other metamorphic and sedimentary raw materials from two Middle and Upper Bed II sites, has enabled us to produce a comprehensive dataset and characterization of the rocks employed by Olduvai hominins, which is used here to establish a referential framework for future studies on Early Stone Age raw material provenancing...

Chan Gyoo Kim
Endoscopic full-thickness resection combined with laparoscopic surgery was recently developed. These procedures could be categorized as "Cut first and then suture" and "Suture first and then cut". "Cut first and then suture" includes laparoscopic and endoscopic cooperative surgery (LECS) and laparoscopy-assisted endoscopic full-thickness resection (LAEFR). Recent studies have demonstrated the safety and efficacy of LECS and LAEFR. However, these techniques are limited by the related exposure of the tumor and gastric mucosa to the peritoneal cavity and manipulation of these organs, which could lead to viable cancer cell seeding and the spillage of gastric juice into the peritoneal cavity...

Adam Hartstone-Rose, Sharlene E Santana
This issue of the Anatomical Record is the first of a two-volume set that focuses on new investigations into behavioral correlates of muscle functional morphology. Much of the research on functional morphology and adaptation to specific functional niches focuses on the shapes of hard-tissues-bones and teeth. Investigations into soft-tissue anatomy tend to be predominantly descriptive with only brief allusion to ontogenetic or evolutionary origins of structures. When muscles are included in analyses of functional systems, their function tends to be oversimplified-usually considered a simple force vector connecting two osteological points, with the force treated as a constant derived from some simple calculation of muscle size...

Analyses of masticatory muscle architecture-specifically fascicle length (FL; a correlate of muscle stretch and contraction speed) and physiological cross-sectional area (PCSA; a correlate of force)-reveal soft-tissue dietary adaptations. For instance, consumers of large, soft foods are expected to have relatively long FL, while consumers of obdurate foods are expected to have relatively high PCSA. Unfortunately, only a few studies have analyzed these variables across large primate samples-an order of particular interest because it is our own...
