Abstract
It is helpful to understand the pathology of Alzheimer’s disease by exploring the relationship between amyloid-β accumulation and cognition. The study explored the relationship between regional amyloid-β accumulation and multiple cognitions and study their application value in the Alzheimer’s disease diagnosis. 135 participants completed 18F-florbetapir Positron Emission Tomography (PET), structural MRI, and a cognitive battery. Partial correlation was used to examine the relationship between global and regional amyloid-β accumulation and cognitions. Then, a support vector machine was applied to determine whether cognition-related accumulation regions can adequately distinguish the cognitively normal controls (76 participants) and mild cognitive impairment (30 participants) groups or mild cognitive impairment and Alzheimer’s disease (29 participants) groups. The result showed that amyloid-β accumulation regions were mainly located in the frontoparietal cortex, calcarine fissure, and surrounding cortex and temporal pole regions. Episodic memory-related regions included the frontoparietal cortices; executive function-related regions included the frontoparietal, temporal, and occipital cortices; and processing speed-related regions included the frontal and occipital cortices. Support vector machine analysis showed that only episodic memory-related amyloid-β accumulation regions had better classification performance during the progression of Alzheimer’s disease. Assessing regional changes in amyloid, particularly in frontoparietal regions, can aid in the early detection of amyloid-related decline in cognitive function.

Abstract
Noise represents a threat to human and wildlife health, triggering physiological and behavioral challenges to individuals living close to sources of extreme noise. Here, we considered airport environments as sources of potentially stressful stimuli for birds and tested if those living near airports are under higher physiological stress than birds living in quiet sites. We used measurements of CORT in feathers (CORTf) as a proxy of chronic stress. We evaluated 14 passerine and 1 non-passerine species, living near three Brazilian airports. We found that, across species, individuals with a better body condition had lower CORTf concentration. At the species level, we found that CORTf concentration was not consistently affected by airport noise. Comparing individuals living in quiet sites with those living near airports, we found that 2 species had higher and 2 had lower CORTf concentrations near airports, while 11 species presented no significant differences between sites. At the population level, model selection indicated that the direction and strength of these differences are weakly related to species’ song frequency (peak frequency), as lower-frequency singers tended to present higher CORTf levels at airport-affected sites. In summary, we were unable to find a consistent response among species, probably due to species-specific differences in their response to anthropogenic disturbances. Instead, we found that species might be affected differently according to their singing spectral frequency and that individuals in good body condition show lower CORTf, suggesting that this measure is consistent with lower physiological stress.
Purifying and balancing selection on embryonic semi-lethal haplotypes in a wild mammal

Published: October 2023

Abstract
Embryonic lethal mutations are arguably the earliest and most severe manifestation of inbreeding depression, but their impact on wild populations is not well understood. Here, we combined genomic, fitness, and life-history data from 5,925 wild Soay sheep sampled over nearly three decades to explore the impact of embryonic lethal mutations and their evolutionary dynamics. We searched for haplotypes that in their homozygous state are unusually rare in the offspring of known carrier parents and found three putatively semi-lethal haplotypes with 27%–46% fewer homozygous offspring than expected. Two of these haplotypes are decreasing in frequency, and gene-dropping simulations through the pedigree suggest that this is partially due to purifying selection. In contrast, the frequency of the third semi-lethal haplotype remains relatively stable over time. We show that the haplotype could be maintained by balancing selection because it is also associated with increased postnatal survival and body weight and because its cumulative frequency change is lower than in most drift-only simulations. Our study highlights embryonic mutations as a largely neglected contributor to inbreeding depression and provides a rare example of how harmful genetic variation can be maintained through balancing selection in a wild mammal population.

Abstract
Whether environmental conditions under exotic tree plantations abandoned in the Western Ghats of India can facilitate the natural regeneration of tropical montane forest (Shola forest) tree species is being debated. In many cases, the exotic tree plantations are being cleared to allow for the restoration of native ecosystems. In this paper, we examined whether exotic tree plantations have indeed a negative effect on the regeneration of Shola forest tree species. For this, we assessed the abundance, diversity, and composition of the regeneration of Shola forest tree species in plantations, each with different dominant tree species (Acacia mearnsii, Pinus sp., and Eucalyptus sp.). We tested the abundance of regenerating native tree species against the main plantation canopy species (plantation type) as well as other environmental factors (aspect, distance to nearest Shola forest, structural diversity, slope, elevation, presence of herbivores, and canopy closure). We found that the number of native tree species regenerating in all plantation types was at an acceptable level: 1960, 1773, and 462 individuals ha−1 for Acacia, Eucalyptus, and Pinus plantations, respectively. A rare fraction analysis showed that the highest number of Shola tree species were regenerating under Acacia mearnsii (25) followed by Eucalyptus (19) and Pinus (8) plantations. The density and diversity of regenerating Shola trees was greatest under Acacia plantations and northern aspects but declined with increasing elevation. The presence of herbivores also reduced the density and diversity of Shola tree regeneration. We concluded that the restoration of Shola forest in the Western Ghats is possible in existing stands of exotic tree species and this process can be accelerated with appropriate silvicultural methods. We additionally recommend that studies involving long-term exclosures can provide valuable insights into the effects of browsing on regeneration and species composition.
ChatGPT in forensic sciences: a new Pandora’s box with advantages and challenges to pay attention
Authors: Dinis-Oliveira Ricardo J , Azevedo Rui M S 
Published: October 2023

Abstract
ChatGPT is a variant of the generative pre-trained transformer (GPT) language model that uses large amounts of text-based training data and a transformer architecture to generate human-like text adjusted to the received prompts. ChatGPT presents several advantages in forensic sciences, namely, constituting a virtual assistant to aid lawyers, judges, and victims in managing and interpreting forensic expert data. But what would happen if ChatGPT began to be used to produce forensic expertise reports? Despite its potential applications, the use of ChatGPT and other Large Language Models and artificial intelligence tools in forensic writing also poses ethical and legal concerns, which are discussed in this perspective together with some expected future perspectives.
The Interplay Between Splicing of Two Exon Combinations Differentially Affects Membrane Targeting and Function of Human CaV2.2

Published: October 2023

Abstract
N-type calcium channels (CaV2.2) are predominantly localized in presynaptic terminals, and are particularly important for pain transmission in the spinal cord. Furthermore, they have multiple isoforms, conferred by alternatively spliced or cassette exons, which are differentially expressed. Here, we have examined alternatively spliced exon47 variants that encode a long or short C-terminus in human CaV2.2. In the Ensembl database, all short exon47-containing transcripts were associated with the absence of exon18a, therefore, we also examined the effect of inclusion or absence of exon18a, combinatorially with the exon47 splice variants. We found that long exon47, only in the additional presence of exon18a, results in CaV2.2 currents that have a 3.6-fold greater maximum conductance than the other three combinations. In contrast, cell-surface expression of CaV2.2 in both tsA-201 cells and hippocampal neurons is increased ∼4-fold by long exon47, relative to short exon47, in either the presence or the absence of exon18a. This surprising discrepancy between trafficking and function indicates that cell-surface expression is enhanced by long exon47, independently of exon18a. However, in the presence of long exon47, exon18a mediates an additional permissive effect on CaV2.2 gating. We also investigated the single-nucleotide polymorphism in exon47 that has been linked to schizophrenia and Parkinson’s disease, which we found is only non-synonymous in the short exon47 C-terminal isoform, resulting in two minor alleles. This study highlights the importance of investigating the combinatorial effects of exon inclusion, rather than each in isolation, in order to increase our understanding of calcium channel function.
Promoting the Well-Being of Older People in Ethiopia: Lost Opportunities Due to the Poverty of Policy

Published: October 2023

Abstract
The world’s population is aging with the fastest growth in the older population projected to take place in Africa. In this article, we present the challenges of the growing older population in Ethiopia, outline some key changes that are needed to address those challenges, and consider the opportunities that can come about when older adults’ basic needs are met and they are supported in contributing to their communities. Older adults in Ethiopia are faced with multidimensional challenges that call for collaborative efforts from different stakeholders at local, regional, and national levels. However, some measures should be given the utmost priority: combating negative attitudes toward older people, strengthening geriatric/gerontology and social work education and research, and developing aging-specific policies and services. Although the challenges faced by older adults in Ethiopia seem like a problem of aging compounded by poverty, the root source of the problem is a poverty of policy fueled by ageism. If income support and appropriate health care was provided to older adults throughout Ethiopia, health and well-being in late life would improve, food and housing insecurity among older adults would lessen, and all Ethiopians could anticipate a dignified late life.

Abstract

Background and Objectives
Providing preferred leisure activities appears to be an important approach to support and empower people receiving adult day services (ADS) allowing them to age in place. To provide the conceptualization for a preference instrument, we actively involved people receiving ADS in exploring the content and structure of their preferences for leisure activities.

Research Design and Methods
We chose a concept mapping methodology and involved 16 people receiving ADS. We systematically reviewed the literature and conducted semistructured interviews to generate a set of 80 preferences. Analysis of structuring these preferences resulted in a 3-dimensional cube with 12 clusters. A graphical representation was then interpreted, and the clusters were labeled.

Results
Our conceptualization divides preferences for leisure activities into the following: 1. Take a trip, 2. Revel in memories and catch up on the news (most important), 3. Do something for yourself and come to rest, 4. Play intelligence and parlor games, 5. Make/produce and try something alone or in a group, 6. Keep fit and cheer others on in sports (least important), 7. Learn, educate, and share knowledge, 8. Have contact with other people, 9. Attend at entertainment, cultural, and amusement events, 10. Enjoy music, your homeland, or other countries, 11. Engage in outdoor activities, and 12. Get involved, offer support, and provide companionship.

Discussion and Implications
Our results may lead to the development of instruments and thus opens the field for further research and theory building on preferences for leisure activities of people receiving ADS.

Abstract

Background
The discovery of effective treatments for major depressive disorder (MDD) may help target different brain pathways. Invasive vagus nerve stimulation (VNS) is an effective neuromodulation technique for the treatment of MDD; however, the effectiveness of the noninvasive technique, transauricular VNS (taVNS), remains unknown. Moreover, a mechanistic understanding of the neural effects behind its biological and therapeutic effects is lacking. This review aimed to evaluate the clinical evidence and the neural and anti-inflammatory effects of taVNS in MDD.

Methods
Two searches were conducted using a systematic search strategy reviewed the clinical efficacy and neural connectivity of taVNS in MDD in humans and evaluated the changes in inflammatory markers after taVNS in humans or animal models of depression. A risk of bias assessment was performed in all human studies.

Results
Only 5 studies evaluated the effects of taVNS in patients with depression. Although the studies demonstrated the efficacy of taVNS in treating depression, they used heterogeneous methodologies and limited data, thus preventing the conduct of pooled quantitative analyses. Pooled analysis could not be performed for studies that investigated the modulation of connectivity between brain areas; of the 6 publications, 5 were based on the same experiment. The animal studies that analyzed the presence of inflammatory markers showed a reduction in the level of pro-inflammatory cytokines or receptor expression.

Conclusions
Data on the clinical efficacy of taVNS in the treatment of MDD are limited. Although these studies showed positive results, no conclusions can be drawn regarding this topic considering the heterogeneity of these studies, as in the case of functional connectivity studies. Based on animal studies, the application of taVNS causes a decrease in the level of inflammatory factors in different parts of the brain, which also regulate the immune system. Therefore, further studies are needed to understand the effects of taVNS in patients with MDD.

Published: October 2023

Abstract

Background
It is unclear whether there are racial/ethnic disparities in the risk of upper respiratory viral infection acquisition and/or lower respiratory manifestations.

Methods
We studied all children and children with asthma aged 6 to 17 years in the National Health and Nutrition Examination Survey (2007–2012) to evaluate (1) the association between race/ethnicity and upper respiratory infection (URI) and (2) whether race/ethnicity is a risk factor for URI-associated pulmonary eosinophilic inflammation or decreased lung function.

Results
Children who identified as Black (adjusted odds ratio [aOR], 1.38; 95% CI, 1.10–1.75) and Mexican American (aOR, 1.50; 95% CI, 1.16–1.94) were more likely to report a URI than those who identified as White. Among those with asthma, Black children were more than twice as likely to report a URI than White children (aOR, 2.28; 95% CI, 1.31–3.95). Associations between URI and pulmonary eosinophilic inflammation or lung function did not differ by race/ethnicity.

Conclusions
Findings suggest that there may be racial and ethnic disparities in acquiring a URI but not in the severity of infection. Given that upper respiratory viral infection is tightly linked to asthma exacerbations in children, differences in the risk of infection among children with asthma may contribute to disparities in asthma exacerbations.
Amphetamine Positivity Prior to Burn Surgery Does not Adversely Affect Intraoperative Outcomes

Published: October 2023

Abstract
The treatment of burn patients using amphetamines is challenging due hemodynamic liabilty and altered physiology. Wide variation exists in the operative timing for this patient population. We hypothesize that burn excision in patients admitted with amphetamine positivity is safe regardless of timing. Data from two verified burn centers between 2017 and 2022 with differing practice patterns in operative timing for amphetamine-positive patients. Center A obtains toxicology only on admission and proceeds with surgery based on hemodynamic status and operative urgency, whereas Center B sends daily toxicology until a negative test results. The primary outcome was the use of vasoactive agents during the index operation, modeled using logistic regression adjusting for burn severity and hospital days to index operation. Secondary outcomes included death and inpatient complications. A total of 270 patients were included, and there were no significant differences in demographics or burn characteristics between centers. Center A screened once and Center B obtained a median of four screens prior to the surgery. The adjusted OR of requiring vasoactive support intraoperatively was not associated with negative toxicology result (P = .821). Having a body surface area burned &gt;20% conferred a significantly higher risk of vasoactive support (adj. OR 13.42 [3.90–46.23], P &lt; .001). Mortality, number of operations, stroke, and hospital length of stay were similar between cohorts. Comparison between two verified burn centers indicates that waiting until a negative amphetamine toxicology result does not impact intraoperative management or subsequent burn outcomes. Serial toxicology tests are unnecessary to guide operative timing of burn patients with amphetamine use.
Utilizing bee foraging behavior in mutational salp swarm for feature selection: a study on return-intentions of overseas Chinese after COVID-19

Published: October 2023

Abstract
We present a bee foraging behavior-driven mutational salp swarm algorithm (BMSSA) based on an improved bee foraging strategy and an unscented mutation strategy. The improved bee foraging strategy is leveraged in the follower location update phase to break the fixed range search of salp swarm algorithm, while the unscented mutation strategy on the optimal solution is employed to enhance the quality of the optimal solution. Extensive experimental results on public CEC 2014 benchmark functions validate that the proposed BMSSA performs better than nine well-known metaheuristic methods and seven state-of-the-art algorithms. The binary BMSSA (bBMSSA) algorithm is further proposed for feature selection by using BMSSA as the selection strategy and support vector machine as the classifier. Experimental comparisons on 12 UCI datasets demonstrate the superiority of bBMSSA. Finally, we collected a dataset on the return-intentions of overseas Chinese after coronavirus disease (COVID-19) through an anonymous online questionnaire and performed a case study by setting up a bBMSSA-based feature selection optimization model. The outcomes manifest that the bBMSSA-based feature selection model exhibits a conspicuous prowess, attaining an accuracy exceeding 93%. The case study shows that the development prospects, the family and job in the place of residence, seeking opportunities in China, and the possible time to return to China are the critical factors influencing the willingness to return to China after COVID-19.
