Positive body image is defined as healthy body-related attitudes that go beyond the absence of distressful symptoms. A warm and secure relationship with an important other person has been linked with attitudes of acceptance and appreciation toward one's body as well as adaptive eating patterns. This study tested whether a ...

CAP-turing the moment: A cage made from DNA can be used to encapsulate a transcription factor (catabolite activator protein, CAP; see figure) without covalent attachment. CAP is shown to stably bind inside the DNA cage at a 1:1 ratio by bending one edge to accommodate the protein. Single-molecule fluorescence measurements ...

During a screening of putative diterpene synthase genes found in public databases using the Aspergillus oryzae expression system, it was found that a single transformant with the ACLA_76850 gene from A. clavatus produced a sesterterpene alcohol, ophiobolin F, and three minor sesterterpene hydrocarbons. The sesterterpene synthase has two catalytically independent ...

A simple method for determining the absolute configuration of oxazolidinones, lactams, and their derivatives using kinetic resolution catalysts is described. The optically pure substrates were acylated using the (S)-HBTM and the (R)-HBTM catalyst, and the faster reaction was determined. An empirical mnemonic was developed for the assignment of the absolute ...

The strength of the interaction between anions and cations in protic ionic liquids (PILs) can be extracted from far-IR spectra. A suitable set of specially synthesized PILs was used to correct the frequency shifts of these low vibrational modes for contributions resulting from changing reduced masses only. The experimental results ...

Only recently has the critical importance of electromagnetic (EM) field interactions in biology and medicine been recognized. We review the phenomenon of resonance signaling, discussing how specific frequencies modulate cellular function to restore or maintain health. The application of EM-tuned signals represents more than merely a new tool in information ...

The swallowtail butterfly, Papilio xuthus, selectively uses a limited number of plants in the Rutaceae family. The butterfly detects oviposition stimulants in leaves through foreleg chemosensilla and requires a specific combination of multiple oviposition stimulants to lay eggs on the leaf of its host plants. In this study, we sought ...

We explored a noninvasive optical method to determine the Joule heating of individual germanium nanowires. Using confocal μ-Raman spectroscopy, variations in the optical phonon frequency, in detail the downshifting of the first-order Stokes Raman band, are correlated to the temperature increase of vapor-liquid-solid grown germanium nanowires under an applied electrical ...

The replacement of dietary carbohydrates with proteins can lower blood pressure (BP), but the mechanisms remain unclear. This randomized, double-blind, parallel-group study aimed to compare 12-h postprandial sympathetic and hemodynamic responses after high-protein (HP) meals and high-carbohydrate (HC) meals. Fifty-two men and women with untreated elevated BP were tested on ...

Conventional density-functional theory (DFT) has the potential to over-bind radical-molecule complexes because of erroneous charge transfer. We examined this behavior by exploring the ability of various DFT approximations to predict fractional charge transfer and by quantifying the over-binding in a series of complexes. It is demonstrated that too much charge ...

The analysis of designer drugs, including those in the synthetic cathinone and piperazine classes, may be complicated by the poor stability of these compounds in biological specimens. The stability of four of these compounds was investigated: 3,4-methylenedioxypyrovalerone, 4-methyl-N-methylcathinone (mephedrone), N-benzylpiperazine and 1-[3-(trifluoromethyl)phenyl]piperazine. Compound stability was monitored in three different biological ...

De novo biosynthesis of male sex pheromone from two bumblebee species (Bombus terrestris and Bombus lucorum) was studied by using in vitro incubations of labial glands (LGs) with radioactive [1,2-(14) C]acetate and deuterated [D(3) ]acetate. The labeled substrate was incorporated into several types of compounds, such as terpenic alcohols, fatty ...

Sulfate-reducing bacteria and archaea are important players in the biogeochemical sulfur cycle. ATP sulfurylase, adenosine 5'-phosphosulfate reductase and dissimilatory sulfite reductase are the key enzymes in the energy conserving process of SO(4)(2-) → H(2)S reduction. This review summarizes recent advances in our understanding of the activation of sulfate to adenosine ...

The degree of phosphorylation of Myosin Light Chain 20 (MLC20) is a major determinant of force generation in smooth muscle. Myosin phosphatases (MP) all contain Protein Phosphatase 1 as catalytic subunits and are the major enzymes that dephosphorylate MLC20. MYPT1, the main regulatory subunit of MP in all smooth muscles, ...

Rapid boosting of memory CD8(+) T cells (T(M)) is essential in cancer immunotherapy and the control of certain infectious diseases. However, effector T cells (T(E)) are a barrier to booster vaccination because they can rapidly kill antigen-bearing APCs before T(M) are engaged. We demonstrate that viral-vectored vaccines delivered by B ...

We report a novel phase separation phenomenon observed in the growth of ternary InxGa1-xAs nanowires by metalorganic chemical vapor deposition. A spontaneous formation of core-shell nanowires is investigated by cross-sectional transmission electron microscopy, revealing the compositional complexity within the ternary nanowires. It has been found that, for InxGa1-xAs nanowires, high ...

Mammalian skeletal muscles undergo adaptation in response to changes in the functional demands upon them, involving mechanical-stress-induced cellular signaling called "mechanotransduction". We hypothesized that p130Cas, which is reported to act as a mechanosensor that transduces mechanical extension into cellular signaling, plays an important role in maintaining and promoting skeletal muscle ...

It has been proposed that the reinforcing properties of drugs of abuse are due, in part, to their ability to enhance memory consolidation. To test this hypothesis, heroin (0.03-3 mg/kg, SC) and d-amphetamine (0.5-2 mg/kg, SC) were administered to male Sprague-Dawley rats immediately or 4 h after training on win-stay ...

Activation of a cellular senescence program is a common response to prolonged oncogene activation or tumor suppressor loss, providing a physiological mechanism for tumor suppression in premalignant cells. The link between senescence and tumor suppression supports the hypothesis that a loss-of-function screen measuring bona fide senescence marker activation should identify ...
