The biochemical characteristics of pink tomato fruits (<i>Solanum lycopersicum</i> L.): mature and after storage
Authors: Molchanova A. V. , Kondratyeva I. Yu. 
Published: March 2024

Relevance. Tomato pink-fruit cultivars and hybrids are of interest for fresh consumption. The biochemical parameters are influenced by the varietal factor and by the growing conditions. It is known that mature tomatoes record low storability. The softening of the fruit is caused by ethylene produced in the ripening fruit. Then pectinase enzymes are synthesized in the fruit tissues, under the action of which the cell walls of the fruit soften. Breeders are creating tomato cultivars whose fruits could be stored for a long time without losing their tasty. The aim of the investigation was to study the biochemical parameters of pink-colored tomato fruits under different ripening conditions. Materials and methods. The plants were grown on the experimental fields of the Laboratory for Breeding and Seed Production of Solanaceae crops. In the Analytical Department, the biochemical composition of pink tomato fruits was studied during harvesting from the field and after laying for storage in the milky ripeness phase according to the following indicators: dry matter, ascorbic acid, total content of water-soluble antioxidants, titratable acidity, monosaccharides, polyphenols and carotenoids. Results. The breeding accession F4 (Lotos x Z6) showed maximum dry matter and monosaccharide content both after storage and in mature fruits. The same sample as F5 (Lotos x Z6) showed the highest ascorbic acid content after storage. Other parameters before and after storage in these samples were comparable. Whereas, breeding accession F6 (Z6 x Lotos) stood out in terms of maximum content of sum of antioxidants in alcoholic extract and content of water-soluble antioxidants after storage.

Published: March 2024

AbstractWhen naturally occurring polysulphate salt dissolves in water, sulphate and calcium ions are released into the water, making it a potential enhanced oil recovery (EOR) fluid. In mature fields the handling of produced water (PW) presents increasing economic and environmental challenges. PW reinjection (PWRI) can reduce these challenges, but because of the PW composition its efficiency as an EOR method is limited. Polysulphate was explored as an additive for PWRI and EOR from carbonate reservoirs.Seawater is known to be a successful injection fluid in carbonates. However, in areas where seawater is not available, nearby water-sources or reservoir PW are used for waterflooding, potentially limiting the recovery factor. In this work polysulphate salt was added to PW and used as imbibition fluid to test its ability of altering wettability of carbonate rock material and improving oil recovery beyond that obtained by PW alone. Complimentary tests including spontaneous imbibition oil recovery tests and chromatographic wettability tests were used to compare wettability alteration and increase in water-wet rock surfaces in mixed-wet chalk.Oil recovery by spontaneous imbibition tests in mixed-wet outcrop chalk showed that PW with added PS (PW-PS) improved oil recovery beyond that obtained by PW only in both secondary and tertiary mode at 90 °C and 110 °C. In tertiary mode at 90 °C a 22 %OOIP increase in oil recovery was obtained by PW-PS imbibition succeeding the secondary mode PW imbibition, while an additional 15 %OOIP was obtained at 110 °C. By adding PS to PW, wettability alteration was induced by the presence of sulphate, generating positive capillary forces, increased spontaneous imbibition of water and improved displacement of crude oil. In these experiments PW-PS was more efficient than seawater and other PS-brines in the oil recovery process. Compared to seawater, which is considered a Smart Water in chalk, PW-PS increased the ultimate oil recovery in secondary mode with 10 %OOIP at 90 °C and 3 %OOIP at 110 °C. Chromatographic wettability tests, performed after the oil recovery tests, confirmed that the PW-PS brine had altered the wettability of the mixed-wet chalk to more water-wet, supporting the high oil recovery results observed by spontaneous imbibition.These findings suggest that the naturally occurring polysulphate salt is a promising additive for improving PW as an injection fluid in carbonate reservoirs. This is especially important in areas where seawater is not available or PWRI is mandatory or necessary for reducing the challenges associated with its processing and disposal.
Oxygen Removal in Water Injection: A Life-Cycle Cost Comparison Between Vacuum Degassing and Membrane Deaeration Technologies
Authors: De Maria S. , Liati A. , Monti M. 
Published: March 2024

Abstract
This paper aims at making an overall comparison based on life-cycle costs (LCC) between vacuum degassing and membrane deaeration, the two main technologies for removing oxygen from injection water in the energy upstream sector. Traditional degassing technology based on vacuum towers (VT), where oxygen is stripped from liquid water falling on random packing under vacuum conditions, has been compared with membrane deaeration (MDA), a potentially emerging technology in which oxygen moves from the liquid phase through a gas-permeable membrane toward an oxygen-depleted gas stream. The comparison was made based on real projects carried out using vacuum degassing on a wide range of capacities and equivalent membrane deaeration (MDA) configurations obtained by simulating the replacement of the towers and their ancillaries with membrane deaeration.
The two deaeration systems were compared in terms of performance, costs/life-cycle costs assessment (LCC), and general characteristics at different operating capacities to identify under which conditions each technology may be preferable.
While MDA is already widely applied in several industrial applications, it has still not found its way into the "injection water" market. The study helps identify the conditions under which MDA might be beneficial, in terms of life-cycle costs to the Upstream O&G sector.

Abstract

Background
People living with advanced, non-malignant chronic conditions often have extensive and complex care needs. Informal or family caregivers often provide the care and support needed by those with advanced chronic conditions at home. These informal caregivers experience many challenges associated with their caring role, which can impact their own wellbeing. Whilst there is growing evidence around the impact on carers, guidance on support for informal caregivers of patients with advanced, non-malignant, chronic conditions is lacking, with little evidence available on effective psychosocial carer interventions. This systematic review explored existing interventions for caregivers of those with advanced, non-malignant, chronic illness, in order to assess the effectiveness of these interventions in improving psychosocial outcomes.
Methods
Electronic databases, Medline, CINAHL, EMBASE and PsycINFO, were searched up to the end of March 2023. Studies meeting the inclusion criteria, focusing on interventions to improve psychosocial outcomes, such as depression, anxiety, quality of life and caregiver burden, in this cohort of caregivers were included. Data were extracted regarding study setting, design, methods, intervention components, and outcomes. Risk of bias and quality assessment were conducted.
Results
5281 articles were screened, ultimately identifying 12 studies for inclusion, reported in 13 publications. A narrative synthesis revealed mixed results. Psychosocial interventions resulted in more significant improvements in psychosocial outcomes than psychoeducational or support interventions; with interventions for carer-patient dyads also reflecting more positive outcomes for caregivers. Evidence-based interventions, guided by an appropriate theoretical model were reportedly more effective in improving caregiver outcomes. Differences in outcomes were related to intervention development, design, delivery, and outcome assessment.
Conclusions
This review, to our knowledge, is the first to explore the effectiveness of interventions in improving psychosocial outcomes for caregivers of those with advanced, non-malignant, chronic conditions. The review highlights the need for more robust, sufficiently powered, high quality trials of evidence-based interventions for caregivers of people with advanced chronic illness. Optimal intervention duration and frequency of sessions is unclear and needs further exploration.

Published: March 2024

Abstract

Emotional appraisals of political stimuli (e.g., videos) have been shown to drive shared neural encoding, which correspond to shared, yet divisive, interpretations of such stimuli. However, mindfulness practice may entrain a form of emotion regulation that de-automatizes social biases, possibly through alteration of such neural mechanisms. The present study combined a naturalistic neuroimaging paradigm and a randomized controlled trial to examine the effects of short-term mindfulness training (MT) (n = 35) vs structurally equivalent Cognitive Reappraisal training (CT) (n = 37) on politically-situated emotions while evaluating the mechanistic role of prefrontal cortical neural synchrony. Participants underwent functional near-infrared spectroscopy (fNIRS) recording while viewing inflammatory partisan news clips and continuously rating their momentary discrete emotions. MT participants were more likely to respond with extreme levels of anger (odds ratio = 0.12, p < .001) and disgust (odds ratio = 0.08, p < .001) relative to CT participants. Neural synchrony-based analyses suggested that participants with extreme emotion reactions exhibited greater prefrontal cortical neural synchrony, but that this pattern was less prominent in participants receiving MT relative to CT (CT > MT; channel 1 ISC = .040, p = .030).

Abstract

Background
Many countries have developed their country/nation-wide multidimensional area-based index on deprivation or socioeconomic status for resource allocation, service planning and research. However, whether each geographical unit proxied by a single index is sufficiently small to contain a relatively homogeneous population remains questionable. Globally, this is the first study that presents the distribution of domestic households by the territory-wide economic status index decile groups within each of the 2,252 small subunit groups (SSUGs) throughout Hong Kong, with a median study population of 1,300 and a median area of 42,400 m2.
Methods
The index development involved 248,000 anonymized sampled household-based data collected from the population census, representing 2·66 million domestic households and 6·93 million population in mid-2021. Our composite index comprises seven variables under income-/wealth-related and housing-related domains with weights determined using the analytic hierarchy process. After ranking all households from the most to the least well-off according to the numeric/ordinal value of each variable and then calculating their weighted rank scores, they were segregated into ten deciles from D1 (top 10% most well-off) to D10 (bottom 10%). Their relative distribution was summarized in a three-dimensional ternary plot to distinguish patterns across the 2,252 SSUGs within the 18 administrative districts.
Results
In Hong Kong, of the 2,252 SSUGs, only one-quarter contain a homogeneous composition of households with similar economic status, while the other three-quarters are heterogeneous to varying extents. Of the 18 administrative districts, only two are concentrated with more homogeneously well-off SSUGs.
Conclusions
Small-sized geographical units may contain a heterogeneous composition of households with diverse economic statuses, underlying the need for more precise information to quantify their relative distribution. Results of this study will be disseminated via an online interactive map dashboard which can serve as a versatile planning tool capable of performing analysis at different varying geographic scales for community-based resource prioritization, service planning and research across different domains.

Abstract

The nuptial flight of ants usually occurs during certain periods of the year. Alate females and males fly out of their nests to mate simultaneously. In the genus Camponotus, sex-specific chemicals are deposited in the male head capsule; however, their roles in nuptial flight have not yet been clarified. This study aimed to elucidate the functions of male-specific chemicals in the Japanese carpenter Camponotus japonicus. First, we identified three chemicals attributed to the male as authentic chemicals: methyl salicylate (MS), methyl 6-methyl salicylate (MMS), and methyl anthranilate (MA). Electroantennogram (EAG) responses to these three chemicals were confirmed to occur in male and female alates. Subsequently, the amounts of MMS and MA in the alate male head capsule were compared before and after flight under laboratory conditions. The amounts of both substances were significantly reduced after flight, suggesting that males secreted these substances during flight. Thereafter, a field trap experiment was conducted in three fields of the Kyoto Prefecture during the nuptial flight season in 2021 using MMS and MA as bites. The number of captured alate males was significantly higher than that of the females, suggesting that these compounds primarily attracted males rather than females. Considering the field conditions, if the local concentration of these chemicals is increased by male aggregation, females may be attracted because EAG responses were also observed in females. Our findings represent a first step toward understanding chemically mediated male lek formation during the process of male aggregation syndrome in this species.

Published: March 2024

Abstract

Purpose: To investigate the safety and efficacy of esketamine combined with butorphanol for postoperative analgesia after cesarean section.
Methods: 160 parturients who underwent cesarean section were randomly divided into two groups: Group S received intraoperative esketaimine infusion with 0.15mg/kg/h and postoperative 0.2mg/kg butorphanol+ 2mg/kg esketaimine for patient-controlled intravenous analgesia (PCIA). Group C received the same volume of 5% glucose infusion and postoperative butorphanol 0.2mg/kg for PCIA. The primary outcome was postoperative analgesic effectiveness as reflected by the number of analgesic pumps pressed during 24h postoperative period by patients. The secondary outcomes included the VAS scores of postoperative pain, Edinburgh Postnatal Depression Scale (EPDS) scores, neonatal Apgar scores, the time to first get out of bed, the gut functional recovery time, the rescue analgesic treatments, and adverse effects.
Results: There was no statistical difference in analgesic effectiveness during the 24h postoperative period (P>0.05). Both the number of analgesic pump presses and VAS scores during the postoperative period were not significantly different between the two groups (P＞0.05). The EPDS scores of Group S at postoperative 8h, 24h, 96h, and one week were lower than in the C group (P<0.05). The incidence of dizziness was higher in Group S (P<0.05).
Conclusion: Supplement of esketamine during the perioperative period can not improve postoperative analgesia after cesarean section, and increases the incidence of adverse effects.
Trial registration: The trial was registered with Chinese Clinical Trial website (www.chictr.org.cn/index.aspx ChiCTR2100054435) on December 27, 2021 (27/12/2021).

Abstract

Due to the exceptional biomedical properties of ultra-high molecular weight polyethylene (UHMWPE), it is used in various biomedical applications including orthopedic applications. Montmorillonite (MMT) as a reinforcement material is excellent to be used in biomedical applications. The purpose of this study is to justify the use of UHMWPE composite as a material for liners in total hip anisotropy (THA). UHMWPE/MMT nanocomposites with different percentages including 1, 3, 5,7, and 10% have been fabricated by two-roll milling and compression molding techniques. The prepared nanocomposite specimens have been characterized using XRD and SEM. The investigations revealed that the hardness, abrasion resistance, Izod energy absorption, compressive modulus, and ultimate compressive strength experienced a notable improvement, with different percentages of nano-clay reinforcement. This experimentation is helpful in predicting the optimal amount of nano-clay with UHMWPE. The mechanical properties enhancement at the optimal percentage of MMT has been found influenced by the dispersion of the nano-clay in the matrix. Additionally, biocompatibility testing in MTT assay with UHMWPE/MMT composite at the optimal composition, exhibited the highest cell growth after 24 h and 96 h incubation. It is concluded that the UHMWPE/5%MMT displayed better biocompatibility and enhanced mechanical properties making attractive candidate for artificial joints.

Published: March 2024

Abstract

Due to the limited reserves of uranium, the abundance of thorium compared to it and other advantages, the development of the thorium fuel cycle is of interest in different countries. The optimization of thorium extraction from a feed solution produced by Saghand ore with Cyanex 272 on a laboratory scale was evaluated by response surface method. The operating variables include Cyanex 272 concentration of 0.001 to 0.2 mol/L, pH of 0 to 2, equilibrium time of 5 to 60 min and aqueous to organic phase ratio of 0.5 to 2.5 were conducted. The results of the variance analysis of the fitted model revealed F = 35.35 and R2 = 0.9695. Based on the results, it can be said that the validated model shows an error of less than 4%. Therefore, the model is in good agreement with the experimental results. It can be said that there are significant interactions between operational parameters, which vindicate different feedbacks of the system in different operational conditions. The results showed that the 4 mol/L sulfuric acid was a suitable agent for recovering thorium ions from the loaded organic phase. In optimum conditions, the thorium purity percentage and thorium stripping efficiency were obtained 99.17 and 94.12%, respectively.

Abstract

A regulatory mechanism for SLC family transporters, critical transporters for sodium and glucose reabsorptions in renal tubule, is incompletely understood. Here, we report an important regulation of SLC family transporter by SETD2, a chromatin remodeling gene whose alterations have been found in a subset of kidney cancers. Kidney-specific inactivation of Setd2 resulted in hypovolemia with excessive urine excretion in mouse and interestingly, RNA-sequencing analysis of Setd2-deficient murine kidney exhibited decreased expressions of SLC family transporters, critical transporters for sodium and glucose reabsorptions in renal tubule. Importantly, inactivation of Setd2 in murine kidney displayed attenuated dapagliflozin-induced diuresis and glucose excretion, further supporting that SETD2 might regulate SLC family transporter-mediated sodium and glucose reabsorptions in renal tubule. These data uncover an important regulation of SLC family transporter by SETD2, which may illuminate a crosstalk between metabolism and epigenome in renal tubule.
