Internalization of help-seeking stigma and the moderating role of familism among Latine adults with chronic pain.

Latine adults with chronic pain face heightened stigmatization of seeking professional psychological help. However, research is needed to test whether stigma is internalized and to identify protective factors. We focus on familism, a value commonly found in collectivist cultures that emphasizes family bonds.

Improve Advance Care Planning: A Brief Report Discussing Goals of Care Interventions to Improve Communication Among Health Care Teams and Patients Maximizing the Use of the Electronic Health Record Tools.

A key element of advance care planning (ACP) is the goals of care (GOC) conversation between the provider and the patient. The value of meaningful GOC conversations for the patient, provider, and health care institution is well documented. However, if the GOC documentation is buried in the medical record, not well defined, or poorly documented, that value is squandered.

Perceived Risks and Therapeutic Benefits of Cannabis Among College Students Amidst the COVID-19 Pandemic.

More than half of the United States has legalized medicinal and/or recreational cannabis. The purpose of the study is to understand cannabis use and perceptions among college students with cannabis experience - 21 years and older - in a legalized cannabis state. Participants included 170 college students, the majority identified as female (72.

Genetic structure and relatedness of brown trout () populations in the drainage basin of the Ölfusá river, South-Western Iceland.

Background: Lake Þingvallavatn in Iceland, a part of the river Ölfusá drainage basin, was presumably populated by brown trout soon after it formed at the end of the last Ice Age. The genetic relatedness of the brown trout in Þingvallavatn to other populations in the Ölfusá drainage basin is unknown. After the building of a dam at the outlet of the lake in 1959 brown trout catches declined, though numbers have now increased.

Examining Students' Online Learning Satisfaction during COVID-19 to Inform Post-Pandemic Program Planning.

Background: Student satisfaction is one of five pillars of quality online learning and is associated with academic achievement. This study aimed to examine nursing students' satisfaction with online learning during COVID-19, their desire to continue online classes, and associated factors.

Methods: A cross-sectional survey was completed by 125 nursing students from a public university.

An 8-year record of phytoplankton productivity and nutrient distributions from surface waters of Saanich Inlet.

Phytoplankton are the base of nearly all marine food webs and mediate the interactions of biotic and abiotic components in marine systems. Understanding the spatial and temporal changes in phytoplankton growth requires comprehensive biological, physical, and chemical information. Long-term datasets are an invaluable tool to study these changes, but they are rare and often include only a small set of measurements.

A Galactooligosaccharide Product Decreases the Rotavirus Infection in Suckling Rats.

The leading cause of gastroenteritis among young children worldwide is the Group A rotaviruses (RV), which produce a wide range of symptoms, from a limited diarrhea to severe dehydration and even death. After an RV infection, immunity is not complete and less severe re-infections usually occur. These infections could be ameliorated by nutritional interventions with bioactive compounds, such as prebiotics.

The joint role of geometry and illumination on material recognition.

Observing and recognizing materials is a fundamental part of our daily life. Under typical viewing conditions, we are capable of effortlessly identifying the objects that surround us and recognizing the materials they are made of. Nevertheless, understanding the underlying perceptual processes that take place to accurately discern the visual properties of an object is a long-standing problem.

Nitrate Consumers in Arctic Marine Eukaryotic Communities: Comparative Diversities of 18S rRNA, 18S rRNA Genes, and Nitrate Reductase Genes.

For photosynthetic microbial eukaryotes, the rate-limiting step in NO assimilation is its reduction to nitrite (NO), which is catalyzed by assimilatory nitrate reductase (NR). Oceanic productivity is primarily limited by available nitrogen and, although nitrate is the most abundant form of available nitrogen in oceanic waters, little is known about the identity of microbial eukaryotes that take up nitrate. This lack of knowledge is especially severe for ice-covered seas that are being profoundly affected by climate change.

Control over the Self-Assembly Modes of Pt(II) Complexes by Alkyl Chain Variation: From Slipped to Parallel π-Stacks.

We report the self-assembly of a new family of hydrophobic, bis(pyridyl) Pt(II) complexes featuring an extended oligophenyleneethynylene-derived π-surface appended with six long (dodecyloxy (2)) or short (methoxy (3)) side groups. Complex 2, containing dodecyloxy chains, forms fibrous assemblies with a slipped arrangement of the monomer units (dPt⋅⋅⋅Pt ≈14 Å) in both nonpolar solvents and the solid state. Dispersion-corrected PM6 calculations suggest that this organization is driven by cooperative π-π, C-H⋅⋅⋅Cl and π-Pt interactions, which is supported by EXAFS and 2D NMR spectroscopic analysis.

Differential expression of glycerol-3-phosphate dehydrogenase isoforms in flight muscles of the Chagas disease vector Triatoma infestans (Hemiptera, Reduviidae).

Flight muscles of Triatoma infestans have two glycerol-3-phosphate dehydrogenase (GPDH) isoforms: GPDH-1 is involved in flight metabolism and GPDH-2 provides lipid precursors. Total GPDH activity was greater in the natural population and almost only due to GPDH-1. Different expression and activity observed between GPDH isoforms in the natural population and the first laboratory generation was not detected in the second laboratory generation.

Synthesis of gold-silver luminescent honeycomb aggregates by both solvent-based and solvent-free methods.

Heterometallic clusters with strong luminescence have been synthesized (see picture: Au(C≡CPh)(2)yellow-red, Ag(2)blue, Ored) from the metalloligand unit [Au(C≡CPh)PPh(3) ] (yellow/red bars) by using both standard solvent-based and solvent-free reactions. The aggregates are stabilized only by acetylide-metal or metal-metal interactions, and their nuclearity is controlled through the addition of different donor ligands.

Electrochemistry of sulfur and polysulfides in ionic liquids.

The electrochemistry of elemental sulfur (S(8)) and the polysulfides Na(2)S(4) and Na(2)S(6) has been studied for the first time in nonchloroaluminate ionic liquids. The cyclic voltammetry of S(8) in the ionic liquids is different to the behavior reported in some organic solvents, with two reductions and one oxidation peak observed. Supported by in situ UV-vis spectro-electrochemical experiments, the main reduction products of S(8) in [C(4)mim][DCA] ([C(4)mim] = 1-butyl-3-methylimidazolium; DCA = dicyanamide) have been identified as S(6)(2-) and S(4)(2-), and plausible pathways for the formation of these species are proposed.

Electrochemistry of Hg(II) salts in room-temperature ionic liquids.

The electrochemistry of HgCl(2) and [Hg(NTf(2))(2)] ([NTf(2)](-)=bis-{(trifluoromethyl)sulfonyl}imide) has been studied in room temperature ionic liquids. It has been found that the cyclic voltammetry of Hg(II) is strongly dependent on a number of factors (e.g.

Environmental impact reduction through ecological planning at Bahia Magdalena, Mexico.

For analyzing basic marine and coastal characteristics we selected the potential sites where shrimp culture could be developed in a large coastal zone, Bahia Magdalena, Baja California Sur, Mexico. Based on our analysis, 6 sites were preselected and field stages of work were then developed to assess the precise suitability of each site in order to develop the proposed aquaculture activities. In ranking the suitability we were able to recommend the most appropriate places to develop shrimp culture in this region.

A new approach for the detection of ethylene using silica-supported palladium complexes.

The coordination of olefins to square-planar Pd(II) and Pt(II) complexes containing 2,9-dimethylphenanthroline ( L1) often involves a change of color associated with a change of geometry at the metal center. In order to obtain suitable colorimetric detectors for ethylene gas, a series of new Pd(II) and Pt(II) compounds with a range of 2,9-disubstituted phenanthroline ligands [2,9-di- n-butyl-1,10-phenanthroline ( L2), 2,9-di- s-butyl-1,10-phenanthroline ( L3), 2,9-diphenyl-1,10-phenanthroline ( L4), and 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (bathocuproine, L5)] have been prepared and their reactivity toward ethylene investigated both in solution and after depositing the detector compounds on a variety of solid supports. The Pd(II) complex [PdCl 2( L2)] supported on silica undergoes a clear color change upon exposure to ethylene, while remaining stable toward air and water, and forms the basis for new simple colorimetric detectors with potential applications in ethylene pipe-leak detection and the monitoring of fruit ripening.

Preparation of AgX (X = Cl, I) nanoparticles using ionic liquids.

Nanoparticles of silver halides have been prepared by mixing silver halide powder with a single liquid phase consisting of an ionic liquid, isooctane, n-decanol and water. Much higher nanoparticle concentrations may be formed with ionic liquids using this new simple method than are found with conventionally applied surfactants. This method also emphasizes the applicability of ionic liquids as versatile components in microemulsions and as solvents for the synthesis of nanomaterials.

An electrochemical study of PCl3 and POCl3 in the room temperature ionic liquid [C4mpyrr][N(Tf)2].

Voltammetric studies of PCl3 and POCl3 have not been reported in the literature to date, probably due to the instability of these molecules in conventional aprotic solvents giving unstable and irreproducible results. From a previous study [Amigues et al. Chem.

A new type of luminescent alkynyl Au4Cu2 cluster.

Changes in the optical properties of an alkynyldigold(I) complex upon reaction with Cu(I) are associated with a complicated structural change to form an unusual Au4Cu2 cluster with metallophilic interactions as well as pi-alkyne coordination.

Their crystal structures have been determined by X-ray diffraction methods and they all present a central Au2Tl2 core formed via one Tl..

Effects of diphosphine structure on aurophilicity and luminescence in Au(I) complexes.

The effects of diphosphine flexibility and bite angle on the structures and luminescence properties of Au(I) complexes have been investigated. A range of diphosphines based on heteroaromatic backbones [bis(2-diphenylphosphino)phenylether (dpephos), 9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene (xantphos), and 4,6-bis(diphenylphosphino)dibenzofuran (dbfphos)] has been used to prepare mono- and digold derivatives. A clear relationship between the presence of aurophilic contacts and the emission properties of dinuclear complexes has been observed, with one of the complexes studied, [Au(2)Cl(2)(micro-xantphos)], exhibiting luminescence thermochromism.
