Abstract

[Display omitted] • The La based nanorod support was synthesized by the hydrothermal method. • The Ni-based supported catalysts were prepared by various methods. • The effects of support morphology and preparation method were studied. • The rod-shaped catalyst prepared by the deposition–precipitation method was the best. • The reaction mechanism of CO 2 methanation was investigated by the in-situ techniques. In this work, the La(OH) 3 nanorods were successfully synthesized by precisely regulating the parameters of the hydrothermal method. Then, a series of Ni-based CO 2 methanation catalysts were fabricated via the incipient-wetness impregnation and deposition–precipitation methods by employing the La(OH) 3 nanorods as the supports. The influences of the support morphology and the preparation method on the metal-support interaction, Ni dispersion, and the surface basicity were carefully investigated based on various techniques, such as XRD, SEM, H 2 -TPR, CO 2 -TPD, XPS, ect. It was found that the rod-shaped La(OH) 3 supported catalyst prepared by the deposition–precipitation method performed the optimum activity and stability. The reason for this could be derived from the confinement effect of the crystal plane of the rod-shaped support, which would promote the formation of the strong metal-support interaction and the construction of the Ni-La interface with high activity. Furthermore, the online-tandem TG-MS and in-situ DRIFTS technologies were used to investigate the thermal decomposition performance of the catalyst precursors in the calcination process and the reaction intermediates of the CO 2 methanation. Therefore, the fundamental roles of support morphology and catalyst preparation method were expected to direct the advancement of the Ni-based nanostructured catalysts with outstanding low-temperature performances.

Abstract

In this work, octahedral, cubic, particle-like, spherical and rod-shaped nano-CeO 2 supports were synthesized by hydrothermal method. CuO/CeO 2 catalysts were then prepared via an ultrasonic-assisted impregnation method, employing these differently shaped CeO 2 supports. The resulting catalysts were tested for their performance in CO oxidation. The findings revealed that the CuO active sites significantly influenced the oxygen storage and release capacity of CeO 2 , thereby improving its catalytic activity for low-temperature CO oxidation. The key factors affecting the CO oxidation performance of CuO/CeO 2 catalysts with different CeO 2 morphologies were investigated through various characterizations. It was found that the specific surface area was not the primary factor in determining catalytic activity. Instead, the exposed crystal planes played a crucial role. By adjusting the crystal plane exposure of CeO 2 , the supported 1CuO/CeO 2 catalysts exhibited different crystal surface configurations. Notably, the 1CuO/CeO 2 -S catalyst, with exposed (100) and (110) crystal planes, and the 1CuO/CeO 2 -P catalyst, with exposed (111), (100), and (110) planes, exhibited higher surface defect concentrations. This increased defect concentration facilitated the formation of Cu+ species, enhancing the redox properties and further improving the overall catalytic performance of CO oxidation. [Display omitted] • Synthesized CeO 2 supports with diverse morphologies using the hydrothermal method. • 1CuO/CeO 2 catalysts exhibited distinct crystal face exposure combinations. • Crystal face exposure of 1CuO/CeO 2 catalyst influenced CO oxidation activity. • 1CuO/CeO 2 -P catalysts demonstrated the highest surface oxygen vacancy concentration. • 1CuO/CeO 2 -P and 1CuO/CeO 2 -S catalysts displayed exceptional CO oxidation activities.

Abstract

In this study we aim to examine gene-environment interactions (GxEs) between genes involved with estrogen metabolism and environmental factors related to estrogen exposure. GxE analyses were conducted with 1970 Korean breast cancer cases and 2052 controls in the case-control study, the Seoul Breast Cancer Study (SEBCS). A total of 11,555 SNPs from the 137 candidate genes were included in the GxE analyses with eight established environmental factors. A replication test was conducted by using an independent population from the Breast Cancer Association Consortium (BCAC), with 62,485 Europeans and 9047 Asians. The GxE tests were performed by using two-step methods in GxEScan software. Two interactions were found in the SEBCS. The first interaction was shown between rs13035764 of NCOA1 and age at menarche in the GE2df model (p-2df = 1.2 x 10-3 ). The age at menarche before 14 years old was associated with the high risk of breast cancer, and the risk was higher when subjects had homozygous minor allele G. The second GxE was shown between rs851998 near ESR1 and height in the GE2df model (p-2df = 1.1 x 10-4 ). Height taller than 160 cm was associated with a high risk of breast cancer, and the risk increased when the minor allele was added. The findings were not replicated in the BCAC. These results would suggest specificity in Koreans for breast cancer risk.Copyright © 2021 by the authors. Licensee MDPI, Basel, Switzerland.

Height taller than 160 cm was associated with a high risk of breast cancer, and the risk increased when the minor allele was added. The findings were not replicated in the BCAC. These results would suggest specificity in Koreans for breast cancer risk.

Abstract

Background/purpose: Hepatitis B surface antigen (HBsAg)-positive renal transplantation recipients must take lifelong immunosuppressants and nucleotide analogues (NAs). We investigated the cellular immune responses of HBsAg-positive renal transplantation recipients taking immunosuppressants and NAs.Methods: Blood samples were collected from HBsAg-positive individuals with end-stage renal disease on the transplant waiting list (Group 1) and renal transplantation recipients taking immunosuppressants and NAs (Group 2) or immunosuppressants without NAs (Group 3). Hepatitis B virus (HBV)-specific pentamers were used to quantify circulating HBV-specific CD8+ T cells.Results: Groups 2 and 3 had higher cellular immune responses, as indicated by significantly lower regulatory T (Treg)/CD8+ T cell ratios than Group 1. With undetectable viral loads under both immunosuppressant and NAs, the CD8+ T cell and HBV-specific CD8+ T cell frequencies were similar in Group 2 and Group 1. Patients in Group 3 did not use NAs and had an elevated viral load and higher HBV-specific CD8+ T cell and IFN-γ-producing HBV-specific CD8+ T cell frequencies, but lower a frequency of programmed death-1 (PD-1)+ HBV-specific CD8+ T cells than the other groups. Increased viral replication in Group 3 resulted in significantly higher CD8+ T cell and IFN-γ-producing CD8+ T cell frequencies than Group 1.Conclusion: Immunosuppressant therapy increases viral replication in HBsAg-positive renal transplant recipients due to disabling or dysregulation of virus-specific CD8+ T cells. The higher cellular immune responses due to lower Treg/CD8+ T cell ratios in HBsAg-positive renal transplant recipients may be one of the reasons to induce liver pathology because of uncontrolled viral replication.

Abstract

Naïve CD8+T cells can differentiate into effector (Teff), memory (Tmem) or exhausted (Tex) T cells. These developmental pathways are associated with distinct transcriptional and epigenetic changes that endow cells with different functional capacities and therefore therapeutic potential. The molecular circuitry underlying these developmental trajectories and the extent of heterogeneity within Teff, Tmemand Texpopulations remain poorly understood. Here, we used the lymphocytic choriomeningitis virus model of acute-resolving and chronic infection to address these gaps by applying longitudinal single-cell RNA-sequencing (scRNA-seq) and single-cell assay for transposase-accessible chromatin sequencing (scATAC-seq) analyses. These analyses uncovered new subsets, including a subpopulation of Texcells expressing natural killer cell-associated genes that is dependent on the transcription factor Zeb2, as well as multiple distinct TCF-1+stem/progenitor-like subsets in acute and chronic infection. These data also revealed insights into the reshaping of Texsubsets following programmed death 1 (PD-1) pathway blockade and identified a key role for the cell stress regulator, Btg1, in establishing the Texpopulation. Finally, these results highlighted how the same biological circuits such as cytotoxicity or stem/progenitor pathways can be used by CD8+T cell subsets with highly divergent underlying chromatin landscapes generated during different infections.

Abstract

Caregivers for spouses with Alzheimer's disease and related dementias (ADRD) experience drastic changes in the marital relationship that may put them at risk for worsening well-being. Perceived partner responsiveness, or feeling cared for, understood, and appreciated by one's spouse, may help mitigate these effects. In this study, we investigated the associations between marital distress, perceived partner responsiveness, and psychological and physiological well-being indicators among ADRD spousal caregivers.

85. A Retrospective Study of the Adjunctive Use of Gabapentin With Benzodiazepines for the Treatment of Benzodiazepine Withdrawal

Author

Leung, Edison, Ngo, Daniel H., Espinoza, Joe A., Beal, Lauren L., Chang, Catherine, Baris, Dalsu A., Lackey, Blake N., Lane, Scott D., and Wu, Hanjing E.

Abstract

Benzodiazepine withdrawal is a widespread problem with potentially severe and deadly consequences. Currently, the only medications available for treating benzodiazepine withdrawal are short-acting and long-acting benzodiazepines. Identifying other drugs to help in treating benzodiazepine withdrawal is necessary. Gabapentin, an anxiolytic drug that is also used off-label to treat alcohol withdrawal, is a potential candidate for modulating benzodiazepine withdrawal. Using electronic records from a large inpatient psychiatric facility, a retrospective study of 172 patients presenting with benzodiazepine withdrawal was conducted to determine if the coincidental use of gabapentin for other medical conditions was associated with better outcomes of benzodiazepine withdrawal (N=57 gabapentin, N=115 no gabapentin). The primary outcomes were hospital length of stay and total amount of benzodiazepines given (lorazepam milligram equivalent). In this retrospective analysis of electronic medical record data, the patients experiencing benzodiazepine withdrawal who received gabapentin as an adjunct to the use of benzodiazepines were administered a smaller amount of benzodiazepines and had a shorter length of hospital stay relative to the comparison group who did not receive adjunctive gabapentin. These results suggest the potential use of gabapentin as an adjunct to the use of benzodiazepines for treating benzodiazepine withdrawal. The limitations of this study included a small sample size and variability in medication management strategies across the sample.

Abstract

Fresh-cut cantaloupe is very perishable due to the mechanical damage and susceptibility to microorganism infections, which limit their shelf life. Cantaloupe is a popular fruit with high moisture content and nutritional value. This study aimed to enhance fresh-cut cantaloupe quality and extend the shelf life by employing soy protein isolates (SPI) coating solutions containing calcium lactate (CaL) and λ-aminobutyric acid (GABA). Cold plasma (CP) was used to augment the antioxidant and antimicrobial activities of the coatings. The coatings were meticulously characterized, and their impact on fresh-cut cantaloupe was assessed through physicochemical and microbiological parameters. The incorporation of CaL and GABA and the CP treatment heightened the antioxidant activity of the SPI coating, resulting in a substantial increase in DPPH and ABTS free radical scavenging activities by 58% and 30%, respectively. Application of the composite coating included a noteworthy 24% reduction in water loss on fresh-cut cantaloupe, maintaining color stability and total soluble solids content. Moreover, the treatment of composite coating effectively controlled microbial growth, ensuring fresh-cut cantaloupe remained in an edible state at the conclusion of the storage period. The coating treatment has extended the shelf life of fresh-cut cantaloupe from 6 d to 10 d at 0 °C. In conclusion, the CP-treated bioactive coating containing CaL and GABA prolonged the shelf life, enhanced nutritional value, and preserved the microbial quality attributes of fresh-cut cantaloupe. • SPI composite coatings were developed to extend the shelf life and maintain the edibility of fresh-cut cantaloupe. • The incorporation of CaL and GABA and the CP treatment heightened the antioxidant activity of the SPI coating. • SPI composite coating was effective in maintaining quality of fresh-cut cantaloupe. • SPI composite coatings effectively controlled bacterial growth on the surface of fresh-cut cantaloupe.

Abstract

IMPORTANCE: Scalable deprescribing interventions may reduce polypharmacy and the use of potentially inappropriate medications (PIMs); however, few studies have been large enough to evaluate the impact that deprescribing may have on adverse drug events (ADEs). OBJECTIVE: To evaluate the effect of an electronic deprescribing decision support tool on ADEs after hospital discharge among older adults with polypharmacy. DESIGN, SETTING, AND PARTICIPANTS: This was a cluster randomized clinical trial of older (≥65 years) hospitalized patients with an expected survival of more than 3 months who were admitted to 1 of 11 acute care hospitals in Canada from August 22, 2017, to January 13, 2020. At admission, participants were taking 5 or more medications per day. Data analyses were performed from January 3, 2021, to September 23, 2021. INTERVENTIONS: Personalized reports of deprescribing opportunities generated by MedSafer software to address usual home medications and measures of prognosis and frailty. Deprescribing reports provided to the treating team were compared with usual care (medication reconciliation). MAIN OUTCOMES AND MEASURES: The primary outcome was a reduction of ADEs within the first 30 days postdischarge (including adverse drug withdrawal events) captured through structured telephone surveys and adjudicated blinded to intervention status. Secondary outcomes were the proportion of patients with 1 or more PIMs deprescribed at discharge and the proportion of patients with an adverse drug withdrawal event (ADWE). RESULTS: A total of 5698 participants (median [range] age, 78 [72-85] years; 2858 [50.2%] women; race and ethnicity data were not collected) were enrolled in 3 clusters and were adjudicated for the primary outcome (control, 3204; intervention, 2494). Despite cluster randomization, there were group imbalances, eg, the participants in the intervention arm were older and had more PIMS prescribed at baseline. After hospital discharge, 4989 (87.6%) participants completed an ADE interview. There was no significant difference in ADEs within 30 days of discharge (138 [5.0%] of 2742 control vs 111 [4.9%] of 2247 intervention participants; adjusted risk difference [aRD] −0.8%; 95% CI, −2.9% to 1.3%). Deprescribing increased from 795 (29.8%) of 2667 control to 1249 (55.4%) of 2256 intervention participants [aRD, 22.2%; 95% CI, 16.9% to 27.4%]. There was no difference in ADWEs between groups. Several post hoc sensitivity analyses, including the use of a nonparametric test to address the low cluster number, group imbalances, and potential biases, did not alter study conclusions. CONCLUSIONS AND RELEVANCE: This cluster randomized clinical trial showed that providing deprescribing clinical decision support during acute hospitalization had no demonstrable impact on ADEs, although the intervention was safe and led to improvements in deprescribing.

Abstract

BACKGROUND: Epidemiological studies consistently indicate that alcohol consumption is an independent risk factor for female breast cancer (BC). Although the aldehyde dehydrogenase 2 (ALDH2) polymorphism (rs671: Glu>Lys) has a strong effect on acetaldehyde metabolism, the association of rs671 with BC risk and its interaction with alcohol intake have not been fully elucidated. We conducted a pooled analysis of 14 case-control studies, with individual data on Asian ancestry women participating in the Breast Cancer Association Consortium. METHODS: We included 12,595 invasive BC cases and 12,884 controls for the analysis of rs671 and BC risk, and 2,849 invasive BC cases and 3,680 controls for the analysis of the gene-environment interaction between rs671 and alcohol intake for BC risk. The pooled odds ratios (OR) with 95% confidence intervals (CI) associated with rs671 and its interaction with alcohol intake for BC risk were estimated using logistic regression models. RESULTS: The Lys/Lys genotype of rs671 was associated with increased BC risk (OR = 1.16, 95% CI 1.03-1.30, p = 0.014). According to tumor characteristics, the Lys/Lys genotype was associated with estrogen receptor (ER)-positive BC (OR = 1.19, 95% CI 1.05-1.36, p = 0.008), progesterone receptor (PR)-positive BC (OR = 1.19, 95% CI 1.03-1.36, p = 0.015), and human epidermal growth factor receptor 2 (HER2)-negative BC (OR = 1.25, 95% CI 1.05-1.48, p = 0.012). No evidence of a gene-environment interaction was observed between rs671 and alcohol intake (p = 0.537). CONCLUSION: This study suggests that the Lys/Lys genotype confers susceptibility to BC risk among women of Asian ancestry, particularly for ER-positive, PR-positive, and HER2-negative tumor types.

Abstract

[Display omitted] In this work, the uniform Cu 2 O submicron-cubes were facilely synthesized by liquid phase reduction method. Then, the Cu 2 O submicron-cubes were further oxidized into Cu 2 O-CuO heterojunction with tunable Cu2+/Cu+ ratios and CuO submicron-cubes by controlling the calcination temperature. The phase transition period during calcination was real-time monitored by the in-situ XRD and in-situ DRIFTS. The obtained materials were investigated as the catalysts of CO oxidation. The results revealed that the Cu 2 O-CuO heterojunction catalysts performed much higher catalytic activities than the Cu 2 O and CuO counterparts. Because the synergistic effect of the heterojunction (Cu2+/Cu+) could increase the surface oxygen vacancy concentration. Furthermore, it was also found that only the Cu 2 O-CuO heterojunction structure with the appropriate Cu2+/Cu+ ratio behaved the optimum catalytic activity. The kinetic studies indicated that the apparent activation energy of CO oxidation was greatly affected by the Cu2+/Cu+ ratio. Therefore, these Cu 2 O-CuO submicron-cubes with heterostructure were considered as the promising CO oxidation catalysts. [ABSTRACT FROM AUTHOR]

Abstract

[Display omitted] • Mesoporous nanosponge MFI supported Ni based catalysts for CO 2 methanation. • Mesoporous nanosponge MFI possessed both mesoporous and microporous channels. • The confinement effect of mesopore stabilized the metallic Ni active sites. • The penetrating effect of micropore made metallic Ni active sites more accessible. • La 2 O 3 modification enhanced the surface basicity and dispersion of metallic Ni. The mesoporous nanosponge MFI silicate zeolite was facilely fabricated by employing the long chain ammonium as the structure-directing agent. The zeolite with both mesoporous and microporous channels were selected as the support of Ni-La catalysts for methanation of CO 2. Various techniques were used to characterize the catalysts systematically. The effects of the La 2 O 3 promotor and pore morphology of the support on the catalytic performance were carefully investigated. Our study demonstrated that La promoter could be beneficial to the increase of the surface basicity and the enhancement of the metallic Ni dispersion. This would intensify the processes of the CO 2 chemisorption and H 2 dissociation in CO 2 methanation. Besides, we also found that the catalyst supported on mesoporous nanosponge MFI zeolite performed higher activity and better long-term stability than the reference catalysts supported on bulk MFI and MCM-48, suggesting that the synergistic effect between the mesoporous and microporous channels displayed unique advantages. Kinetic study revealed that both the nanosponge structure and La 2 O 3 promoter contributed to decreasing the reaction activation energy. Therefore, the present highly dispersed Ni-La catalyst over mesoporous nanosponge MFI zeolite promised a potential catalyst candidate for low-temperature CO 2 methanation reaction.

Abstract

The Ni monometallic catalyst usually exhibits poor CO2methanation activity, although its low cost is beneficial for conducting large-scale application in industries. Herein, the transition metal (Mn, Fe, Co, and Cu)-doped Ni-based bimetallic catalysts loaded on mesoporous Ce0.8Zr0.2O2solid solution were prepared to address this challenge in CO2methanation. We found that the Co-doped catalysts exhibited much higher activity than the corresponding counterparts. Therefore, the relationship between the Co/Ni ratio and activity was further investigated to acquire the optimum ratio. The obtained catalysts were characterized by various measurements. The results demonstrated that doping the second transition metals could promote Ni dispersion and strengthen metal–support interaction. Resultantly, serious agglomeration of the metallic active sites was successfully inhibited. Besides, we also carried out the in situdiffuse reflectance infrared spectroscopy and online temperature-programmed surface reaction of CO2methanation to study the possible reaction intermediates and pathways over the Ni–Co bimetallic catalysts. A dynamic study was also conducted to further study the effect of the doped transition metals on the apparent activation energies. Besides, the present research also revealed that the Ni–Co synergistic effect significantly improved the low-temperature activity by regulating the reaction intermediates. As a result, the Ni–Co bimetallic catalysts supported by mesoporous Ce0.8Zr0.2O2solid solution were considered as a series of promising and efficient low-temperature CO2methanation catalysts.
