Humans exhibit sex differences in the prevalence of many neurodevelopmental disorders and neurodegenerative diseases. Here, we generated one of the largest multi-brain-region bulk transcriptional datasets for the rhesus macaque and characterized sex-biased gene expression patterns to investigate the translatability of this species for sex-biased neurological conditions. We identify patterns similar to those in humans, which are associated with overlapping regulatory mechanisms, biological processes, and genes implicated in sex-biased human disorders, including autism. We also show that sex-biased genes exhibit greater genetic variance for expression and more tissue-specific expression patterns, which may facilitate rapid evolution of sex-biased genes. Our findings provide insights into the biological mechanisms underlying sex-biased disease and support the rhesus macaque model for the translational study of these conditions.

A number of species have recently recovered from near-extinction. Although these species have avoided the immediate extinction threat, their long-term viability remains precarious due to the potential genetic consequences of population declines, which are poorly understood on a timescale beyond a few generations. Woolly mammoths (Mammuthus primigenius) became isolated on Wrangel Island around 10,000 years ago and persisted for over 200 generations before becoming extinct around 4,000 years ago. To study the evolutionary processes leading up to the mammoths' extinction, we analyzed 21 Siberian woolly mammoth genomes. Our results show that the population recovered quickly from a severe bottleneck and remained demographically stable during the ensuing six millennia. We find that mildly deleterious mutations gradually accumulated, whereas highly deleterious mutations were purged, suggesting ongoing inbreeding depression that lasted for hundreds of generations. The time-lag between demographic and genetic recovery has wide-ranging implications for conservation management of recently bottlenecked populations.

Review
Eyed needles are among the most iconic of Paleolithic artifacts, traditionally seen as rare indicators of prehistoric clothing, particularly tailoring. However, recent finds across Africa and Eurasia show that other technologies like bone awls also facilitated the creation of fitted garments. Nonetheless, the advent of delicate eyed needles suggests a demand for more refined, efficient sewing. This refinement may signify two major developments: the emergence of underwear in layered garment assemblages, and/or a transition in adornment from body modification to decorating clothes, as humans covered themselves more completely for thermal protection. Archaeological evidence for underwear is limited, but the Upper Paleolithic saw an increase in personal ornaments, some sewn onto clothing. Eyed needles may mark a pivotal shift as clothes acquired the social functions of dress, decoupling clothing from climate and ensuring its enduring presence.

Rosacea is a chronic and recurrent inflammatory skin disease affecting the center of the face that causes burning and itching sensations and changes in aesthetics. Liang Xue Wu Hua Tang (LXWHT) is a classic herbal formulation that is efficacious and has been widely used in the clinical treatment of rosacea; however, the pharmacological mechanisms remain unclear. The aim of the present study was to investigate the mechanism of action of LXWHT using network pharmacology and molecular docking. The Traditional Chinese Medicine System Pharmacology database was searched to identify the active ingredients and pharmacological targets of LXWHT, and the GeneCard, Disgenet, and Gene Expression Omnibus databases were applied to screen rosacea-related targets. Cytoscape software was used to visualize the protein-protein interaction network, and network topology analysis was used to identify core targets. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses were performed for the core targets. Molecular docking simulations and visualization were performed using Maestro and PyMOL, respectively. A total of 43 active compounds and 28 potential targets for LXWHT treatment of rosacea were selected for analysis. The Gene Ontology/Kyoto Encyclopedia of Genes and Genomes results indicated that LXWHT may exert therapeutic effects on rosacea by intervening in immune pathways including tumor necrosis factor pathway, interleukin-17 pathways, and Toll-like receptor signaling pathways. Chemokine ligand 2, interferon-γ, interleukin-1ß, peroxisome proliferator-activated receptor-γ, and matrix metallopeptidase 9 may be the core therapeutic target. Quercetin, stigmasterol, kaempferol, beta-sitosterol, luteolin, beta-carotene, baicalein, acetin, and isorhamnetin were predicted to be the key active ingredients. LXWHT may exert therapeutic effects in the treatment of rosacea by modulating immunity and angiogenesis, laying the foundation for further research.

Observational Study
Clinical application and effect evaluation of acupoint thread embedding therapy and traditional Chinese medicine treatment based on menstrual cycle characteristics in the management of breast hyperplasia: An observational study.
To evaluate the effectiveness of the combination of acupoint embedding therapy and traditional Chinese medicine dialectical treatment regimen in improving clinical symptoms, promoting tumor regression, controlling adverse reactions and complications, and enhancing patient satisfaction by comparing and analyzing the clinical data of 120 breast tumor patients. One hundred twenty patients with breast cancer were divided into a treatment group (60 cases) and a control group (60 cases) according to different treatment plans. Patients in the treatment group received a combination of acupoint embedding therapy and traditional Chinese medicine dialectical treatment based on different time points of the menstrual cycle. Including the proportion of reduction in the number of breast masses, the proportion of reduction in mass size, changes in pain severity scores, tumor regression rate, regression time, incidence of adverse reactions and complications, and patient satisfaction. Statistical software was used to analyze the data to evaluate differences between the 2 groups. In terms of clinical symptoms, the proportion of reduction in the number of breast masses in the treatment group averaged 50%, significantly higher than the 25% in the control group; the proportion of reduction in mass size averaged 40%, also higher than the 15% in the control group; and the improvement in pain severity scores was also superior to the control group. Regarding tumor regression, the tumor regression rate in the treatment group reached 85%, with an average regression time of 6.2 weeks, both significantly better than the 55% and 9.8 weeks in the control group. In terms of adverse reactions and complications, the incidence rate in the treatment group was relatively low, and no serious adverse events occurred. Patient satisfaction surveys showed that the treatment group had significantly higher satisfaction with treatment effectiveness, treatment process, and physician service attitude compared to the control group. Based on clinical data from 120 breast tumor patients, the results of this study indicate that breast tumor patients treated with a specific treatment regimen have significant advantages in improving clinical symptoms, tumor regression, controlling adverse reactions and complications, and patient satisfaction. This treatment regimen has high clinical application value and deserves further promotion.

This study aims to critically reassess existing systematic reviews (SR) on Traditional Chinese Exercises (TCE) for treating Chronic Obstructive Pulmonary Disease (COPD). The primary objectives include synthesizing available evidence, evaluating the methodological quality of reviews and overall evidence, and providing comprehensive insights into the effectiveness of different TCE types in managing COPD. Sinomed, CNKI, VIP, Wanfang, PubMed, Cochrane Library, and Web of Science were searched from inception to April 2023 for SR literature on the treatment of COPD with TCE. The extracted data from the included SRs encompassed various aspects such as general information, study population, intervention measures, meta-analysis results, and conclusions. The methodological quality of the included SRs was assessed using the AMSTAR II tool. Additionally, the GRADE tool was used to determine the evidence level of outcome indicators. This study included 17 SRs and 4 types of TCE. The CCA was 0.041, indicating a slight overlap between the primary studies. Notably, one study was rated as low quality on the AMSTAR II scale, while the rest were classified as critically low quality. The results from the GRADE evaluation revealed 26 pieces of very low-quality evidence, 55 pieces of low-quality evidence, and 17 pieces of moderate-quality evidence. The moderate-quality evidence suggests that Liuzijue effectively improves TCM syndrome scores in patients with COPD. Additionally, low-quality evidence suggests that Liuzijue improves patients' lung function (FEV1, FVC) and quality of life (CAT, MRC/mMRC). Similarly, low-quality evidence suggests that Baduanjin can improve patients' lung function (FEV1%, FVC) and quality of life (SGRQ). Low-quality evidence also suggests that Health Qigong can significantly improve patients' exercise endurance (6MWD). No SR reported TCE-related adverse reactions. TCE interventions are effective and safe in the treatment of COPD. Different types of TCE have varying effects on outcomes in COPD patients. However, these findings are limited by the generally low methodological and evidence quality of the included SRs. Therefore, it is strongly recommended to improve study designs to obtain higher-quality clinical evidence and to strictly follow SR protocols.

Randomized Controlled Trial
BACKGROUND
Blood stasis (BS) refers to a pattern of symptoms resulting from circulatory dysfunction or stagnation in the human body. Due to its historical origin and diverse interpretations, communication between patients and doctors of traditional Korean medicine (DKMs) presents challenges. Efforts to improve patients understanding in traditional Korean medicine (TKM) have led to the development of disease-specific standard clinical practice guidelines. However, there is a limited focus on creating clinical practice guidelines or informative leaflet specifically addressing BS, which is a frequently encountered pattern of symptoms in TKM.
METHODS
This study aimed to bridge the gap between patients and DKMs by developing an informative leaflet focusing on BS for metabolic diseases. We assessed its appropriateness through expert advisory meetings and the Delphi process, and evaluated its clinical effectiveness. We conducted a prospective, randomized, crossover trial to compare the clinical effectiveness of using BS leaflets in TKM treatment. The hypothesis investigated whether the leaflet group would show higher scores in satisfaction of DKMs' explanations, understanding of DKMs' explanations, improving the reliability of TKM, satisfaction with treatment time, improvement in explanations compared to previous TKM experiences, and necessity of managing BS treatment, compared to the no-leaflet group.
RESULTS
In a study involving 40 patients (mean age: 62.3 ± 7.8 years), symptoms persisted for an average of 16.75 ± 9.3 hours daily, with a severity rating of 2.53. The leaflet group exhibited significantly higher satisfaction scores than the no-leaflet group in all aspects (all P < .0001). After confirming the absence of sequence and period effects using a linear-mixed effect model, we were able to ascertain the presence of a treatment effect, as evidenced by statistically significant higher scores across all survey items in the leaflet group compared to the no-leaflet group (all P < .0001).
CONCLUSION
Expert consensus on symptoms aligning with the BS pattern resulted in the development of an informative leaflet. Its utilization notably improved patient satisfaction, comprehension, and trust in TKM treatment, unaffected by temporal influences, thus demonstrating its clinical effectiveness. In summary, the BS leaflet significantly enhanced patient understanding and optimized treatment procedures.

X-ray computed tomography (XRCT) imaging allows non-destructive visualization of the structure of various materials. Applied to wooden objects, it allows determination of their morphologies or manufacturing techniques, but also measurement of growth ring widths. We have applied XRCT to a selection of 38 mummy labels. This funerary furniture, made up of endemic or imported tree species, has survived thanks to environmental conditions in very large quantities in regions in Middle and Upper Egypt and is featured now in museum collections across the globe. Mummy labels thus represent a unique and abundant data source to build floating or absolutely dated dendrochronological chronologies for this period. Here we discuss the possible contributions and limitations of XRCT for the analysis of these artifacts and show that the approach allows identification of discriminating markers for the identification of certain species on the transverse plane, but that the insufficient resolution of the tangential and radial planes normally prevents formal identification of species. By contrast, XRCT undeniably enhances the visibility of toolmarks (in terms of numbers and depth), and thereby allows highlighting marks that remain invisible to the naked eye; XRCT also provides key insights into cutting methods and the calibers used and yields new information on silvicultural practices and the knowhow of Egyptian craftsmen. Finally, the measurement of ring widths on XRCT imagery is also more accurate than what can be achieved by traditional dendrochronological measurements, especially in the case of cuts realized on a slab. The approach also confirms the limited potential of local broadleaved species for dendrochronological approaches due to unreadable or poorly visible tree rings and mostly short tree-ring sequences.

UNLABELLED
The gut microbiome has the potential to buffer temporal variations in resource availability and consumption, which may play a key role in the ability of animals to adapt to a broad range of habitats. We investigated the temporal composition and function of the gut microbiomes of wild common marmosets () exploiting a hot, dry environment-Caatinga-in northeastern Brazil. We collected fecal samples during two time periods (July-August and February-March) for 2 years from marmosets belonging to eight social groups. We used 16S rRNA gene amplicon sequencing, metagenomic sequencing, and butyrate RT-qPCR to assess changes in the composition and potential function of their gut microbiomes. Additionally, we identified the plant, invertebrate, and vertebrate components of the marmosets' diet via DNA metabarcoding. Invertebrate, but not plant or vertebrate, consumption varied across the year. However, gut microbiome composition and potential function did not markedly vary across study periods or as a function of diet composition. Instead, the gut microbiome differed markedly in both composition and potential function across marmosets residing in different social groups. We highlight the likely role of factors, such as behavior, residence, and environmental heterogeneity, in modulating the structure of the gut microbiome.
IMPORTANCE
In a highly socially cohesive and cooperative primate, group membership more strongly predicts gut microbiome composition and function than diet.
