Knowledge about biological shape has important implications in biology and biomedicine, but the underlying genetic mechanisms for shape variation have not been well studied. Statistical models play a pivotal role in mapping specific quantitative trait loci (QTLs) that contribute to biological shape and its developmental trajectories. We describe and assess ...

Ultrasonic vocalizations (USVs) are emitted in response to a sexual partner before, during, and after copulation. These vocalizations are the so-called 50-kHz USVs and can be subdivided into flat and frequency-modulated (FM) 50-kHz trill calls. In the present series of experiments, the potential unconditioned and conditioned incentive properties of female ...

A series of novel lanthanide metal-organic frameworks were synthesized using a ligand featuring three carboxylate groups stationed on a triazinyl central motif. The readily accessible multiple Lewis basic triazinyl N atoms allow for complexation of incoming metal ions. Such interactions have been established quantitatively.

The management of articular cartilage defects remains challenging and controversial. Hyaline cartilage has limited capacity for self-repair and post-injury cartilage is predominantly replaced by fibrocartilage through healing from the subchondral bone. Fibrocartilage lacks the key properties that characterize hyaline cartilage such as capacity for compression, hydrodynamic permeability and smoothness of ...

Abstract Current models of health anxiety suggest that fear resulting from false alarms to perceived threats to one's health results in the development of hypochondriasis and related disorders. Disgust has been proposed as an affective response that may function as an etiological and maintenance mechanism in health anxiety. Moreover, the ...

BACKGROUND: MicroRNAs (miRNAs) are a class of short non-coding RNAs that function in diverse biological processes. Aberrant miR-152 expression has been frequently reported in various malignant tumors. However, the mechanism of miR-152 in prostate cancer (PCa) remains unclear. This study aims to determine the function of miR-152 in PCa cells ...

Depression in fathers has been associated with impaired parenting, which, in turn, may function as a central environmental mechanism underlying the adverse effects of paternal depression on children's development. Despite this, evidence suggests that many depressed fathers are able to maintain positive relationships with their children, and little is known ...

We present a theoretical framework and a simplified simulation model for the co-evolution of knowledge and event memory, both termed SARKAE (Storing and Retrieving Knowledge and Events). Knowledge is formed through the accrual of individual events, a process that operates in tandem with the storage of individual event memories. In ...

PNA does it better: Peptide nucleic acid (PNA) oligomers were attached to gold nanoparticles (AuNPs) through a variety of mono- and trithiol linkers. These functionalized particles had sufficient stability for sequence-specific self-assembly onto gold surfaces in the absence of ions or surfactants. The nanoparticle surface densities obtained were superior to ...

Preeclampsia is characterized by an imbalance in angiogenic factors. Urinary prolactin (PRL) levels and its antiangiogenic PRL fragments have been associated with disease severity. In this study, we assessed whether these biomarkers are associated with an increased risk of adverse maternal and perinatal outcomes in preeclamptic women. We studied 501 ...

In 3 studies we explored when 3-year-olds would imitate novel words in utterances produced by adult speakers. Child and experimenter took turns in requesting objects from a game master. The experimenter always went first and always preceded the object's familiar name with a novel adjective (e.g., "the dilsige duck"). In ...

Oxygen tension plays an important role in the regulation of cellular processes. During hematopoietic stem cell (HSC) differentiation, HSCs migrate from one stem cell niche to the next, each with a different oxygen tension that determines which signalling pathways are on and off, determining the differentiation stage of the cell. ...

Methyl mercury (MeHg) is a neurotoxicant with adverse effects on the development of the nervous system from fish to man. Despite a detailed understanding of the molecular mechanisms by which MeHg affects cellular homeostasis, it is still not clear how MeHg causes developmental neurotoxicity. We performed here a genome-wide transcriptional ...

We have performed a density functional theory (DFT) investigation of the interactions of H2O2, H2O and HO radicals with clusters of ZrO2, TiO2 and Y2O3. Different modes of H2O adsorption onto the clusters were studied. In almost all the cases the dissociative adsorption is more exothermic than molecular adsorption. At ...

Abstract Bacteriophages are viruses that infect bacteria. It was shown that bacteriophage therapy is an effective method of combating bacterial infections, including infections caused by antibiotic-resistant bacterial strains. One of the main obstacles to widespread use of phage preparations is limited knowledge regarding the influence of bacteriophages on human organisms. ...

Poly(ionic liquids) (PILs) are an important class of technologically relevant materials. However, charac-terization of well-defined polyionic materials remains a chal-lenge. Herein, we have developed a simple and versatile gel permeation chromatography (GPC) methodology for mo-lecular weight characterization of PILs with a variety of ani-ons. PILs with narrow molecular weight distribution ...

Previous osmotic pressure studies of two non-homologous dihydrofolate reductase (DHFR) enzymes found tighter binding of the NADPH cofactor upon addition of neutral osmolytes. This result is consistent with water release accompanying binding. In contrast, osmotic stress studies found weaker binding of the dihydrofolate (DHF) substrate for both type I and ...

We experimentally determine the order of multi-photon induced luminescence of aluminum nanoantennas fabricated on a non-conductive substrate using electron-beam lithography to be 2.11 (±0.10). Furthermore, we optically characterize these nanostructures via linear dark-field microscopy and nonlinear multi-photon laser excitation. We hereby observe a splitting of peak positions when the antenna ...
