The timing of puberty is a highly polygenic childhood trait that is epidemiologically associated with various adult diseases. Using 1000 Genomes Project-imputed genotype data in up to ∼370,000 women, we identify 389 independent signals (P < 5 × 10(-8)) for age at menarche, a milestone in female pubertal development. In Icelandic data, these signals explain ∼7.4% of the population variance in age at menarche, corresponding to ∼25% of the estimated heritability. We implicate ∼250 genes via coding variation or associated expression, demonstrating significant enrichment in neural tissues...

Alpha-1-antitrypsin deficiency (AATD) is an inherited disease characterized by emphysema and liver disease. AATD is most often caused by a single amino acid substitution at amino acid 342 in the mature protein, resulting in the Z mutation of the alpha-1-antitrypsin gene (ZAAT). This substitution is associated with misfolding and accumulation of ZAAT in the endoplasmic reticulum (ER) of hepatocytes and monocytes, causing a toxic gain of function. Retained ZAAT is eliminated by ER-associated degradation and autophagy...

Enterovirus 71 (EV71) is a major public health threat that requires rapid point-of-care detection. Here, we developed a surface-enhanced Raman spectroscopy (SERS)-based scheme that utilized protein-induced aggregation of colloidal gold nanostars (AuNS) to rapidly detect EV71 without the need for fabricating a solid substrate, Raman labels or complicated sample handling. We used AuNS (hydrodynamic diameter, DH of 105.12 ± 1.13 nm) conjugated to recombinant scavenger receptor class B, member 2 (SCARB2) protein with known affinity to EV71...

Infectious bursal disease (IBD) causes significant clinical and economic losses to the poultry industry worldwide. Current vaccine programs using live attenuated and inactivated vaccines have numerous drawbacks. As an alternative solution to control IBD, a Marek's disease virus (MDV) vector vaccine (rMDV-VP2) expressing the VP2 gene of infectious bursal disease virus (IBDV) has been developed. In this study, the protective efficacy of rMDV-VP2 was evaluated in a dose-related experiment which showed that a single dose of 1000 PFU was sufficient to fully protect chickens against IBDV infection...

REVIEW
Marek Cebecauer, Martin Hof, Mariana Amaro
In this perspective we summarize current knowledge of the effect of monosialoganglioside GM1 on the membrane-mediated aggregation of the β-amyloid (Aβ) peptide. GM1 has been suggested to be actively involved in the development of Alzheimer's disease due to its ability to seed the aggregation of Aβ. However, GM1 is known to be neuroprotective against Aβ-induced toxicity. Here we suggest that the two scenarios are not mutually exclusive but rather complementary, and might depend on the organization of GM1 in membranes...

Mohammad Heidari, Phillip C Delekta
Marek's disease virus (MDV), a highly cell-associated oncogenic α-herpesvirus, is the causative agent of T cell lymphoma and neuropathic disease called Marek's disease. The skin is the only anatomical site where infectious enveloped cell-free virions are produced and shed into the environment. Studies have demonstrated that MDV infection induces immunological responses within the skin, including the release of cytokines and the recruitment of T lymphocytes. The host immune response, however, is not sufficient to block replication and shedding of the virus particles from the skin...

Marek's disease virus is the etiological agent of a major lymphoproliferative disorder in poultry and the prototype of the Mardivirus genus. Primary avian somatic cells are currently used for virus replication and vaccine production, but they are largely refractory to any genetic modification compatible with the preservation of intact viral susceptibility. We explored the concept of induction of viral replication permissiveness in an established pluripotent chicken embryonic stem cell-line (cES) in order to derive a new fully susceptible cell-line...

Heterozygous mutations in the GRN gene lead to progranulin (PGRN) haploinsufficiency and cause frontotemporal dementia (FTD), a neurodegenerative syndrome of older adults. Homozygous GRN mutations, on the other hand, lead to complete PGRN loss and cause neuronal ceroid lipofuscinosis (NCL), a lysosomal storage disease usually seen in children. Given that the predominant clinical and pathological features of FTD and NCL are distinct, it is controversial whether the disease mechanisms associated with complete and partial PGRN loss are similar or distinct...

Anemia is a frequent, although often underestimated, clinical condition accompanying thyroid diseases. In spite of the fact that anemia and thyroid dysfunction often occur simultaneously, the causative relationship between these two disorders remains ambiguous. Thyroid hormones stimulate erythrocytes precursors proliferation directly, as well as via erythropoietin production enhancement, whereas iron-deficient anemia negatively influences thyroid hormonal status. Thus, different forms of anemia might emerge in the course of thyroid dysfunction...

OBJECTIVES: Correct positioning of the acetabular cup is the key for successful total-hip replacement. In common clinical practice, the target alignment of the cup is defined with respect to the anterior pelvic plane. In patients with substantial anterior pelvic plane inclination, this condition may lead to inappropriate distribution of the load on the cup, as most of the forces exerted within the hip joint act along the vertical axis. With the known pelvic inclination, it is possible to readjust the position of the cup with respect to the individual posture of the patient...

This study investigates how complex motor-cognitive activities are processed in the subthalamic nucleus (STN) and internal globus pallidum (GPi), as adverse neuropsychiatric effects may accompany deep brain stimulation (DBS), mainly in Parkinson's disease (PD) and STN-DBS. Dystonia patients with GPi-DBS electrodes (n = 5) and PD subjects (n = 5) with STN-DBS electrodes performed two tasks: (1) copying letters; and (2) writing any letter other than that appearing on the monitor. The cognitive load of the second task was greater than that of the first...

It is assumed that the spread of breast cancer cells via the lymphatic system might be influenced by inflammatory reactions and/or the application of chemotherapy or molecularly targeted therapy. Therefore, we analysed survival according to lymphatic vessel density (LVD), lymphovascular invasion (LVI) (both assessed using podoplanin as immunohistochemical marker of lymphatic endothelium) and well-established clinico-pathological features in a group of 358 patients with invasive ductal breast cancer: 139 chemotherapy-naïve (pT1-2/pN0/M0) and 219 treated with chemotherapy (pT1-4/pN1-3/M0)...

REVIEW
Marek Chojnowski
Infrared thermal imaging (IRT) is a non-invasive, non-contact technique which allows one to measure and visualize infrared radiation. In medicine, thermal imaging has been used for more than 50 years in various clinical settings, including Raynaud's phenomenon and systemic sclerosis. Imaging and quantification of surface body temperature provides an indirect measure of the microcirculation's overall performance. As such, IRT is capable of confirming the diagnosis of Raynaud's phenomenon, and, with additional cold or heat challenge, of differentiating between the primary and secondary condition...

A 2-mo-old pet chicken ( Gallus domesticus) was presented because of lameness and a hind limb mass of 1 mo duration. Radiographs revealed a soft tissue mass extending from the mid-femur into the body wall. Cytology of a sample obtained from a fine-needle aspirate was unremarkable. The bird was prepared for surgical investigation of the mass but died acutely at the time of pre-medication. Autopsy revealed an extradural mesenchymal neoplasm that focally compressed the lumbar spinal cord, extended into and along the adjacent nerve structures, and displaced the kidneys, skeletal muscle, and body wall...

BACKGROUND: Serum paraoxonase 1 (PON1), an enzyme associated with high - density lipoproteins (HDL) particles, inhibits the oxidation of serum lipoproteins and cell membranes. PON1 activity is lower in patients with atherosclerosis and in inflammatory diseases. The systemic inflammatory response provoked during cardiopulmonary bypass grafting may contribute to the development of postoperative complications. The aim of the present study was to estimate the dynamic changes in paraoxonase 1 (PON1) activity towards paraoxon and phenyl acetate during and after coronary artery surgery...
