Distinct paths to alcohol problems: Impacts of childhood maltreatment, attachment insecurity, and interpersonal problems

Childhood maltreatment is a strong risk factor for increased alcohol use and alcohol-related problems. One possible explanation for these associations is the influence of dysfunctional attachment styles and interpersonal problems in adulthood. Individuals who have experienced childhood maltreatment are likely to develop maladaptive interpersonal styles due to insecure attachment. Maladaptive interpersonal styles may increase emotional distress, which in turn, can make these individuals vulnerable to alcohol use and alcohol-related problems. Using data from 508 undergraduate students, this study examined the associations between three types of childhood maltreatment (i.e., sexual abuse, punishment that included physical abuse, and a negative home atmosphere that included neglect), alcohol use, and alcohol-related problems via insecure attachment and interpersonal problems. The results showed that punishment predicted alcohol problems via avoidant attachment and selfish interpersonal style. Sexual abuse and negative home atmosphere predicted alcohol consumption through anxious attachment and selfless interpersonal style. In addition, sexual abuse directly predicted alcohol problems. These findings provide new insights for the field of childhood maltreatment and addiction literature.

Social interaction anxiety and perceived coping efficacy: Mechanisms of the association between minority stress and drinking consequences among sexual minority women

Sexual minority women (SMW; individuals who identify as women and as lesbian, bisexual, or with another sexual minority identity) are at increased risk for problematic alcohol use compared to their heterosexual counterparts. This increased risk has been attributed to minority stress. However, longitudinal research examining associations between minority stress and alcohol use outcomes is extremely limited and examinations of these associations at the daily level are nearly non-existent. Further, few longitudinal studies have examined mechanisms through which minority stress may impact alcohol use. We utilized data from a 14-day daily diary study of 98 SMW to examine daily-level associations between experiences of minority stress, alcohol consumption and consequences, and two proposed mediators of these associations (perceived coping efficacy, social interaction anxiety). Results indicated that on days when participants experienced minority stress events, they experienced lower coping efficacy, higher social interaction anxiety, and more drinking consequences than usual. Minority stress was not associated with same-day alcohol consumption. Perceived coping efficacy and social interaction anxiety mediated the same-day association between minority stress and drinking consequences. No prospective associations were significant, suggesting that studies with multiple assessments per day may be necessary to detect immediate effects of minority stress. Findings highlight the potential impact of daily experiences of minority stress on alcohol consequences and provide evidence that two general psychological processes may be mechanisms through which minority stress impacts alcohol consequences. These results provide evidence of a need for interventions that teach SMW skills for coping with minority stress and its psychological consequences.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 2516-33-8. Safety of Cyclopropylmethanol.

Sedentary behaviour in cardiovascular disease patients: Risk group identification and the impact of cardiac rehabilitation

Background: Sedentary behaviour (SB) is potentially an important target to improve cardiovascular health. This study 1) compared SB between cardiovascular disease (CVD) patients and age-matched controls, 2) identified characteristics associated with high SB levels, and 3) determined the impact of contemporary cardiac rehabilitation (CR) on SB. Methods: For objective 1, we recruited 131 CVD patients and 117 controls. All participants were asked about their general characteristics and medical history. SB was assessed by an objective accelerometer (activPAL3 micro). For objective 2, 2584 CVD patients were asked to fill in a questionnaire about their general characteristics, lifestyle, medical history and their SB. For objective 3, 131 CVD patients were followed over time and measured, pre-, directly post- and 2 months post-CR. Results: Objective 1. CVD patients spent 10.4 h/day (Q25 9.5; Q75 11.2) sedentary which was higher compared to healthy controls (9.4 h/day [Q25 8.4; Q75 10.29]). Objective 2. CVD patients being male, single or divorced, employed, physically inactive, reporting high alcohol consumption, living in an urban environment, having comorbidities and cardiac anxiety demonstrated a greater odds for large amounts of SB. Objective 3. The CR program significantly reduced sedentary time (-0.4 h/day [95%CI-0.7; -0.1]), which remained lower at 2-months post-CR (-0.3 h/day 195%CI -0.6; -0.03]). Conclusions: CVD patients had greater amounts of objectively measured sedentary time compared to healthy controls. Sedentarism was associated with personal- and lifestyle characteristics, and comorbidities. Participation in a contemporary CR program slightly reduced sedentary time, but tailored interventions are needed to target SB in CVD patients. (C) 2020 The Authors. Published by Elsevier B.V.

Reducing the destructive effect of ambient humidity variations on gas detection capability of a temperature modulated gas sensor by calcium chloride

Despite the successful detection performance of electronic nose in laboratories, they face challenges for use in the industry due to their accuracy reduction resulted from variable ambient properties especially relative humidity (RH) variation which is studied here. Responses of a single temperature modulated metal oxide gas sensor have been analyzed by SVM and k-NN methods to achieve a detector for low concentration levels of acetone, ethanol, 1-propanol and 1-butanol in air. The classifier models were designed and tested under different train-test conditions which showed that studied gases can be detected by the classifier if only they were measured in the same train and test environmental conditions and deviation of humidity level from train condition, reduces the detection accuracy to less than 60%. The accuracy increases by expanding the training dataset and training the system with responses carried out for gas with various RH contents. It was also shown that by using CaCl2 at the rout of gas flow, the destructive effect of RH variation is reduced and the detection accuracy increases to above 90%, while to achieve this accuracy, it is not necessary to train the system in all humidity conditions. By this method, the number of required test for system training reduces drastically. The method can be generalized to other electronic nose and gas detectors which suffer from humidity variations.

Strategies to utilize naturally occurring protein architectures as nanovehicles for hydrophobic nutraceuticals

The development of protein-based nanovehicles to improve water solubility, stability and bioavailability of hydrophobic or poorly soluble nutraceuticals has become a subject of fast increasing interest in the field. This review mainly presents the state-of-art knowledge about the utilization of naturally occurring nanostructured protein architectures (casein micelles, ferritin and legume oligomeric globulins) as nanovehicles for hydrophobic nutraceuticals or drugs, through a disassembly and reassembly strategy. First, the composition and structural features of these three naturally occurring architectures are briefly summarized. Then, many strategies and techniques to mediate the disassembly and reassembly of these naturally occurring architectures are comprehensively reviewed, including pH-, urea-, alcohol-, high pressure-, and heat-mediated disassembly and reassembly (or dissociation and reassociation). Last, reassembled casein micelles, ferritin (or apoferritin) and legume oligomeric protein nanoparticles are demonstrated to perform as outstanding nanovehicles for improving water dispersion, stability and bioactivities of many nutraceuticals or drugs. Due to the rapidly increasing consumer interests for health-benefiting foods, this review is of importance for the development of a kind of outstanding nanovehicles for nutraceuticals with a great potential to be applied in functional foods or drug formulations.

Effective degradation of tetracycline via polyvinyl alcohol /Bi2WO6 hybrid hydrogel with easy separation

Developing inexpensive and stable photocatalysts with easy separation for the degradation of antibiotics is highly needed. In this study, a three-dimensional poly(vinyl alcohol) (PVA)/Bi2WO6 (BWO) (PVA/BWO) hybrid hydrogel photocatalyst with easy separation was constructed via freeze-thaw process and then was used to remove Tetracycline (TC) from water. The obtained hydrogels were characterized by various techniques. SEM image and EDS mapping show the successful decoration of BWO and the BWO is homogenously distributed on the PVA substrate. Results of the photocatalytic experiment and total organic carbon content (TOC) measurement show that the constructed PVA/BWO hydrogel could degrade TC effectively under visible light irradiation, even after the PVA/BWO hydrogel had been recycled for five times. Results of XRD, SEM and EDS mapping on the fresh and used PVA/BWO hydrogel confirm its relatively good stability in structure. The possible reaction pathways and mechanism of TC degradation were also analyzed. The PVA/BWO hybrid hydrogel with easy separation could be a new alternative with great potential in efficient removal of persistent organic pollutants.

Proton transfer reaction mass spectrometry investigations of phthalate esters via direct headspace sampling

One of the most common environmentally relevant groups of pollutants are phthalate esters. After decades of industrial use, they have become ubiquitous in the environment and analytical methods to chemically detect them in trace amounts are required. In this study, details of Proton Transfer Reaction-Mass Spectrometry (PTR-MS) investigations for the reactions of phthalic acid and ten phthalate esters with H3O+ as a function of the reduced electric field are presented. A characteristic product ion observed for several of the phthalate esters is protonated phthalic anhydride (m/z 149.02, C8H5O3+). However, not all of the phthalates investigated in this study fragment to produce this product ion following proton transfer. For alkyl diester phthalates, loss of the corresponding alcohol results in the main product ion, but its abundance decreases with increasing alkyl chain length, whilst in comparison for the dialkyl ester phthalates, the protonated phthalic anhydride ion abundance increases with increasing alkyl chain length and with increasing reduced electric field. Collisional induced dissociation in the drift tube of the PTR-MS is shown to be useful as means to manipulate the underlying ion chemistry, leading to unique product ions distinctive to phthalates. The results reported in this work represent a wealth of new data that will be of use for developing a PTR-MS analytical method for the quick, selective and reliable identification of phthalates in the environment.

Key aroma-active compounds in brown sugar and their influence on sweetness

Brown sugar (non-centrifugal cane sugar) is popular for its pleasant caramel-like aroma and sweetness. Vacuum simultaneous steam distillation and extraction (V-SDE) and gas chromatography-mass spectrometry (GC-MS) was used to study the volatile fraction of brown sugar. To further determine the aroma-active compounds in brown sugar, gas chromatography-mass spectrometry-olfactometry (GC-MS-O) were used in conjunction with aroma extraction dilution analysis (AEDA), odor activity values (OAVs), and sensory evaluation to analyze the effects of the key aroma-active compounds on sweetness. A total of 37 aroma-active compounds were obtained, mainly including ketones, pyrazines, alkanes, phenols and alcohols, which contributed caramel, sweet and fruity notes to brown sugar. Among them, furfural, benzeneacetaldehyde, 2,3-butanedione, beta-damascenone, 2-methoxyphenol, dihydro-2-methyl-3(2H)-furanone, 2-furanmethanol and butyrolactone could significantly enhance the sweetness of sugar solution because of the congruency of the aroma attributes and sweetness.

Highly sensitive MWCNTs/SiNWs hybrid nanostructured sensor fabricated on silicon-chip for alcohol vapors detection

The present work focuses on the fabrication of highly sensitive, stable and fast response alcohol sensor using MWCNTs/SiNWs hybrid nanostructure. Herein, vertically aligned Silicon Nanowires (SiNWs) were synthesized on Silicon (Si) chip using Metal Assisted Chemical Etching (MACE) process, which were decorated by Multiwall Carbon Nanotubes (MWCNTs) and resulted into a MWCNTs/SiNWs hybrid nanostructure. These types of MWCNTs were separately grown by using Chemical Vapor Deposition (CVD) technique. The structural analysis and characterization of as-grown materials along with fabricated hybrid nanostructure were done by using different techniques such as Scanning Electron Microscope (SEM), Transmission Electron Microscope (TEM), Raman spectrometer and X-Ray diffractometer. The prepared materials were observed to be dense having high yield and uniformity throughout the structure. The alcohol vapors sensing properties, such as sensitivity, selectivity, repeatability, response & recovery characteristics, of the fabricated MWCNTs/SiNWs sensor, were investigated at room temperature. The data was recorded in the form of changes in sensor response with respect to time and analyzed using the mechanism of interaction of materials with the analyte gas species. The as-fabricated sensor exhibits not only excellent response similar to 1.42 and selectivity for alcohol concentration of 1 ppm under atmospheric conditions at room temperature but also, it’s response time (3 s) and recovery time (5 s) is quite fast along with excellent reproducible nature. Most importantly, the sensor recovered to its original state without applying any external energy source. Hence, all the measured properties indicate the better operational performance of the fabricated sensor and therefore, could be suitably employed in various applications such as alcohol industries, fuel processing and other societal problems.

Nano SnO2 and Sb2O3 combined with CNTs as a high-capacity lithium storage material

The combination of Sb2O3 or SnO2 with graphene has become a research hotpot in recent years. However, several problems, namely the loading of the active materials, space utilization in composites, and the intrinsic volume expansion of Sb2O3 and SnO2, have yet to be fully resolved. To overcome these disadvantages, in this work Sb2O3/carbon nanotubes (CNTs)/SnO2 composite have been synthesized, in which the CNTs act as a network to ensure the electronic conductivity and buffer of the volume expansion. The SnO2 nanoparticles are aligned by the CNTs and Sb2O3 is dispersed in the voids between them. Space utilization and the loading of the oxides are thereby maximized. Moreover, the resultant composite retains small amount of water or alcohol, which does not affect the cyclic stability, but may have increased the ionic and electronic conductivity, improving the electrochemical performance. A discharge capacity of 910 mAh g(-1) after 250 cycles at 100 mA g(-1) is realized for Sb2O3/CNT/SnO2. Moreover, the contribution of the pseudocapacitance to the rate discharge capability is obvious, which arises from the different heterointerfaces between Sb2O3/CNTs, CNTs/SnO2 or Sb2O3/SnO2. The homogenous distribution of Sn and Sb in CNTs after cycling leads to a lower discharge voltage, improving the application prospects. Although some collapse and cracks are detected, the CNTs network connects the oxides, ensuring the structural stability and the cyclic stability of Sb2O3/CNT/SnO2. This strategy represents a new concept for the design of multi-component materials for lithium storage.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 1777-82-8 is helpful to your research. Category: alcohols-buliding-blocks.
