Abstract
Mollemycin A (MOMA) is a unique glyco-hexadepsipeptide-polyketide that was isolated from a Streptomyces sp. derived from the Australian marine environment. MOMA exhibits remarkable inhibitory activity against both drug-sensitive and multidrug-resistant malaria parasites. Optimizing MOMA through structural modifications or product enhancements is necessary for the development of effective analogues. However, modifying MOMA using chemical approaches is challenging, and the production titer of MOMA in the wild-type strain is low. This study identified and characterized the biosynthetic gene cluster of MOMA for the first time, proposed its complex biosynthetic pathway, and achieved an effective two-pronged enhancement of MOMA production. The fermentation medium was optimized to increase the yield of MOMA from 0.9 mg L-1 to 1.3 mg L-1, a 44% boost. Additionally, a synergistic mutant strain was developed by deleting the momB3 gene and overexpressing momB2, resulting in a 2.6-fold increase from 1.3 mg L-1 to 3.4 mg L-1. These findings pave the way for investigating the biosynthetic mechanism of MOMA, creating opportunities to produce a wide range of MOMA analogues, and developing an efficient strain for the sustainable and economical production of MOMA and its analogues.

Abstract
OBJECTIVE This study was aimed to create and validate a risk prediction model for the incidence of osteopenia in individuals with abdominal obesity. METHODS Survey data from the National Health and Nutrition Examination Survey (NHANES) database for the years 2013-2014 and 2017-2018 was selected and included those with waist circumferences ≥102 m in men and ≥88 cm in women, which were defined as abdominal obesity. A multifactor logistic regression model was constructed using LASSO regression analysis to identify the best predictor variables, followed by the creation of a nomogram model. The model was then verified and evaluated using the consistency index (C-index), area under the receiver operating characteristic (ROC) curve (AUC), calibration curve, and decision curve analysis (DCA). Results Screening based on LASSO regression analysis revealed that sex, age, race, body mass index (BMI), alkaline phosphatase (ALP) and Triglycerides (TG) were significant predictors of osteopenia development in individuals with abdominal obesity (P < 0.05). These six variables were included in the nomogram. In the training and validation sets, the C indices were 0.714 (95 % CI: 0.689-0.738) and 0.701 (95 % CI: 0.662-0.739), respectively, with corresponding AUCs of 0.714 and 0.701. The nomogram model exhibited good consistency with actual observations, as demonstrated by the calibration curve. The DCA nomogram showed that early intervention for at-risk populations has a net positive impact. CONCLUSION Sex, age, race, BMI, ALP and TG are predictive factors for osteopenia in individuals with abdominal obesity. The constructed nomogram model can be utilized to predict the clinical risk of osteopenia in the population with abdominal obesity.

Abstract
Objectives This study was aimed to develop a nomogram that can accurately predict the likelihood of cognitive dysfunction in individuals with abdominal obesity by utilizing various predictor factors. Methods A total of 1490 cases of abdominal obesity were randomly selected from the National Health and Nutrition Examination Survey (NHANES) database for the years 2011-2014. The diagnostic criteria for abdominal obesity were as follows: waist size ≥ 102 cm for men and waist size ≥ 88 cm for women, and cognitive function was assessed by Consortium to Establish a Registry for Alzheimer's Disease (CERAD), Word Learning subtest, Delayed Word Recall Test, Animal Fluency Test (AFT), and Digit Symbol Substitution Test (DSST). The cases were divided into two sets: a training set consisting of 1043 cases (70%) and a validation set consisting of 447 cases (30%). To create the model nomogram, multifactor logistic regression models were constructed based on the selected predictors identified through LASSO regression analysis. The model's performance was assessed using several metrics, including the consistency index (C-index), the area under the receiver operating characteristic (ROC) curve (AUC), calibration curves, and decision curve analysis (DCA) to assess the clinical benefit of the model. Results The multivariate logistic regression analysis revealed that age, sex, education level, 24-hour total fat intake, red blood cell folate concentration, depression, and moderate work activity were significant predictors of cognitive dysfunction in individuals with abdominal obesity (p < 0.05). These predictors were incorporated into the nomogram. The C-indices for the training and validation sets were 0.814 (95% CI: 0.875-0.842) and 0.805 (95% CI: 0.758-0.851), respectively. The corresponding AUC values were 0.814 (95% CI: 0.875-0.842) and 0.795 (95% CI: 0.753-0.847). The calibration curves demonstrated a satisfactory level of agreement between the nomogram model and the observed data. The DCA indicated that early intervention for at-risk populations would provide a net benefit, as indicated by the line graph. Conclusion Age, sex, education level, 24-hour total fat intake, red blood cell folate concentration, depression, and moderate work activity were identified as predictive factors for cognitive dysfunction in individuals with abdominal obesity. In conclusion, the nomogram model developed in this study can effectively predict the clinical risk of cognitive dysfunction in individuals with abdominal obesity.

Abstract
BACKGROUND Follow-up studies on auricular reconstruction procedures have reported postoperative complications; some of which can only be reversed with revision surgery. This study aims to provide a feasible surgical strategy based on the Nagata method for patients requiring secondary revision and verify mid-term aesthetic outcomes. METHODS Secondary auricular reconstructions based on the Nagata method were performed on seven patients seeking secondary revision between 2017 and 2021. Scores of a five-point Likert scale and artificial intelligence ratings based on convolutional nerve networks were used as outcome measures. RESULTS Five patients underwent complete two-stage ear reconstruction, and the other two patients underwent the first-stage microtia procedure only. Few complications were observed, except in Case 4; this patient required an additional minor surgery after frame exposure 6 weeks after the first-stage procedure. All revised ears showed clear anatomical structures, and all patients were satisfied with the aesthetic results. Statistical analysis showed a significant increase in postoperative versus preoperative scores by convolutional neural network models (p < 0.05). Cases 5 and 6, which involved projection surgeries only, had decreased artificial intelligence appearance scores postoperatively. CONCLUSION After adequate preoperative evaluation, secondary auricle reconstruction based on the Nagata method can achieve reliable aesthetic outcomes with few complications.

Abstract
PURPOSE Patients with Graves' orbitopathy (GO) have characteristic facial expressions that are different from those of healthy individuals due to the combination of somatic and psychiatric symptoms. However, the facial expressions of GO patients have not yet been described and analyzed systematically. Thus, the present study aimed to present the facial expressions of GO patients and explore their applications in clinical practice. METHODS Facial image and clinical data of 943 GO patients were included, and 126 patients answered quality of life (GO-QOL) questionnaires. Each patient was labeled for one facial expression. Then, a portrait was drawn for every facial expression. Logistic and linear regression was performed to analyze the correlation between facial expression and clinical indicators, including QOL, disease activity and severity. The VGG-19 network model was utilized to discriminate facial expressions automatically. RESULTS Two groups, i.e., the non-negative emotion (neutral, happy) and the negative emotion (disgust, angry, fear, sadness, surprise), and seven expressions of GO patients were systematically analyzed. Facial expression was statistically associated with GO activity (P = 0.002), severity (P < 0.001), QOL visual functioning subscale scores (P = 0.001), and QOL appearance subscale score (P = 0.012). The deep learning model achieved satisfactory results (accuracy 0.851, sensitivity 0.899, precision 0.899, specificity 0.720, F1 score 0.899, and AUC 0.847). CONCLUSIONS As a novel clinical sign, facial expression holds the potential to be incorporated into GO assessment system in the future. The discrimination model may assist clinicians in real-life patient care.

Abstract
Objective: To compare the differences in the prevalence of mild micro-hepatic encephalopathy (MHE) among patients with cirrhosis by using the psychometric hepatic encephalopathy score (PHES) and the Stroop smartphone application (Encephal App) test. Methods: This prospective, multi-center, real-world study was initiated by the National Clinical Medical Research Center for Infectious Diseases and the Portal Hypertension Alliance and registered with International ClinicalTrials.gov (NCT05140837). 354 cases of cirrhosis were enrolled in 19 hospitals across the country. PHES (including digital connection tests A and B, digital symbol tests, trajectory drawing tests, and serial management tests) and the Stroop test were conducted in all of them. PHES was differentiated using standard diagnostic criteria established by the two studies in China and South Korea. The Stroop test was evaluated based on the criteria of the research and development team. The impact of different diagnostic standards or methods on the incidence of MHE in patients with cirrhosis was analyzed. Data between groups were differentiated using the t-test, Mann-Whitney U test, and χ (2) test. A kappa test was used to compare the consistency between groups. Results: After PHES, the prevalence of MHE among 354 cases of cirrhosis was 78.53% and 15.25%, respectively, based on Chinese research standards and Korean research normal value standards. However, the prevalence of MHE was 56.78% based on the Stroop test, and the differences in pairwise comparisons among the three groups were statistically significant (kappa = -0.064, P < 0.001). Stratified analysis revealed that the MHE prevalence in three groups of patients with Child-Pugh classes A, B, and C was 74.14%, 83.33%, and 88.24%, respectively, according to the normal value standards of Chinese researchers, while the MHE prevalence rates in three groups of patients with Child-Pugh classes A, B, and C were 8.29%, 23.53%, and 38.24%, respectively, according to the normal value standards of Korean researchers. Furthermore, the prevalence rates of MHE in the three groups of patients with Child-Pugh grades A, B, and C were 52.68%, 58.82%, and 73.53%, respectively, according to the Stroop test standard. However, among the results of each diagnostic standard, the prevalence of MHE showed an increasing trend with an increasing Child-Pugh grade. Further comparison demonstrated that the scores obtained by the number connection test A and the number symbol test were consistent according to the normal value standards of the two studies in China and South Korea (Z = -0.982, -1.702; P = 0.326, 0.089), while the other three sub-tests had significant differences (P < 0.001). Conclusion: The prevalence rate of MHE in the cirrhotic population is high, but the prevalence of MHE obtained by using different diagnostic criteria or methods varies greatly. Therefore, in line with the current changes in demographics and disease spectrum, it is necessary to enroll a larger sample size of a healthy population as a control. Moreover, the establishment of more reliable diagnostic scoring criteria will serve as a basis for obtaining accurate MHE incidence and formulating diagnosis and treatment strategies in cirrhotic populations.

Abstract
Tumor cells endure continuous DNA replication stress, which opens the way to cancer development. Despite previous research, the prognostic implications of DNA replication stress on lung adenocarcinoma (LUAD) have yet to be investigated. Here, we aimed to investigate the potential of DNA replication stress-related genes (DNARSs) in predicting the prognosis of individuals with LUAD. Differentially expressed genes (DEGs) originated from the TCGA-LUAD dataset, and we constructed a 10-gene LUAD prognostic model based on DNARSs-related DEGs (DRSDs) using Cox regression analysis. The receiver operating characteristic (ROC) curve demonstrated excellent predictive capability for the LUAD prognostic model, while the Kaplan-Meier survival curve indicated a poorer prognosis in a high-risk (HR) group. Combined with clinical data, the Riskscore was found to be an independent predictor of LUAD prognosis. By incorporating Riskscore and clinical data, we developed a nomogram that demonstrated a capacity to predict overall survival and exhibited clinical utility, which was validated through the calibration curve, ROC curve, and decision curve analysis curve tests, confirming its effectiveness in prognostic evaluation. Immune analysis revealed that individuals belonging to the low-risk (LR) group exhibited a greater abundance of immune cell infiltration and higher levels of immune function. We calculated the immunopheno score and TIDE scores and tested them on the IMvigor210 and GSE78220 cohorts and found that individuals categorized in the LR group exhibited a higher likelihood of deriving therapeutic benefits from immunotherapy intervention. Additionally, we predicted that patients classified in the HR group would demonstrate enhanced sensitivity to Docetaxel using anti-tumor drugs. To summarize, we successfully developed and validated a prognostic model for LUAD by incorporating DNA replication stress as a key factor.

Abstract
Objective: To describe the clinical characteristics, diagnosis, genetic features and treatment of hereditary pulmonary hypertension complicated with suspected hereditary hemorrhagic telangiectasia (HHT). Methods: Firstly, we summarized and analyzed the clinical data of two cases of suspected HHT admitted to the Department of Pulmonary and Critical Care Medicine, the Second Xiangya Hospital, Central South University. Secondly, the genes of peripheral blood of patients and their families were completely sequenced and sanger sequencing was performed to verify the variation sites, and then the mRNA deletion caused by the variation was further verified. Thirdly, "HHT" "FPAH" and "BMPR2 gene variation" were used as keywords,and the related literatures of Wanfang database and PubMed database from January 2000 to November 2021 were searched and reviewed. Results: We found two patients in a family from Yiyang, Hunan province, who had symptoms of hemoptysis or pulmonary hypertension without epistaxis or other clinical features of HHT. However, both patients had pulmonary vascular abnormalities and pulmonary hypertension in their lungs. We found that BMPR2 gene variation (NM_001204.7:c.1128+1G>T) was positive and ENG, ACVRL1 and SMAD4 genes were negative. Family analysis and Sanger verification were carried out on 16 individuals in 4 generations of the family (7 of whom were found to carry the mutant gene), and then transcriptional level mRNA sequencing further confirmed that the variation resulted in the deletion of exon 8 and exon 9, and amino acid sequence estimation revealed that the amino acids of the protein from 323 to 425 were deleted. We thought that the incomplete translation of BMPR2 gene could lead to BMPRⅡ dysfunction. Therefore, it was diagnosed as hereditary pulmonary hypertension with suspected HHT. Both patients were suggested to reduce the pulmonary artery pressure, and at the same time, the whole-body imaging examination should be performed to screen other arteriovenous malformations, and the annual cardiac color Doppler ultrasound should be reviewed to evaluate the changes of pulmonary artery pressure. Conclusions: Hereditary pulmonary hypertension (HPAH) is a group of diseases with increasing pulmonary vascular resistance caused by genetic factors, including familial PAH and simple PAH. Variation in the BMPR2 gene is an important pathogenic factor of HPAH. Therefore, we should pay attention to the inquiry of family history when we clinically encounter young patients with pulmonary hypertension. If the cause is unknown, genetic testing is recommended. HHT is a rare autosomal dominant genetic disease. The possibility of this disease should be considered in clinical manifestations such as familial pulmonary vascular abnormality, pulmonary hypertension and recurrent epistaxis. There is no effective specific treatment for HPAH and HHT, which are treated symptomatically (including blood pressure reduction and hemostasis, etc.). It is suggested for these patients that pulmonary artery pressure should be dynamically monitored and have genetic counseling before giving birth.

In this study, eight new fasamycins (3, 4, 6, and 8-12) along with five known analogues (1, 2, 5, 7, and 13) were obtained by the overexpression of two phosphopantetheinyl transferases (PPtases) in Streptomyces kanamyceticus and biocatalytic transformation with two halogenases. These new compounds displayed significant activity against Staphylococcus aureus and Bacillus subtilis, in particular, C-29-methyl and C-2/C-22-halogen derivatives. This study increases the chemical diversity of bioactive fasamycin derivatives and provides useful halogenation tools for engineering their scaffolds.

Abstract
Biological mineralization is a natural process manifested by living organisms in which inorganic minerals crystallize under the scrupulous control of biomolecules, producing hierarchical organic-inorganic composite structures with physical properties and design that galvanize even the most ardent structural engineer and architect. Understanding the mechanisms that control the formation of biominerals is challenging in the biomimetic engineering of hard tissues. In this regard, the contribution of cryogenic electron microscopy (cryo-EM) has been nothing short of phenomenal. By preserving materials in their native hydrated status and reducing damage caused by ion beam radiation, cryo-EM outperforms conventional transmission electron microscopy in its ability to directly observe the morphologic evolution of mineral precursor phases at different stages of biomineralization with nanoscale spatial resolution and subsecond temporal resolution in 2 or 3 dimensions. In the present review, the development and applications of cryo-EM are discussed to support the use of this powerful technique in dental research. Because of the rapid development of cryogenic sample preparation techniques, direct electron detection, and image-processing algorithms, the last decade has witnessed an exponential increase in the use of cryo-EM in structural biology and materials research. By amalgamating with other analytic techniques, cryo-EM may be used for qualitative and quantitative analyses of the kinetics and thermodynamic mechanisms in which organic macromolecules participate in the transformation of mineral precursors from their original liquid state to amorphous and ultimately crystalline phases. The present review concentrates on the biomineralization of calcium phosphate mineral phases, while that of calcium carbonate, silica, and magnetite is only briefly mentioned. Bioinspired organic matrix-mediated inorganic crystallization strategies are discussed from the perspective of tissue regeneration engineering.

Abstract
Bone marrow stromal cell antigen 2 (BST2) has been reported to act as an oncogene in the tumorigenesis of numerous types of cancer. Bioinformatics analysis has predicted the binding interaction between BST2 and specificity protein 1 (SP1) and the involvement of SP1 in pancreatic cancer. Therefore, the present study set out to verify this interaction and determine how it may affect pancreatic cancer progression. Normal human pancreatic duct epithelial cells (HPDE6-C7) and pancreatic cancer cell lines (SW1990, BxPC3, PANC1 and PSN-1) were selected for western blotting and reverse transcription-quantitative PCR detection of BST2 expression. Colony formation, Cell Counting Kit-8 and wound healing assays were performed to detect the proliferative and migratory abilities of PANC1 cells following transfection with small interfering RNA against BST2. The expression of proliferation and migration markers were assayed using western blotting. Chromatin immunoprecipitation and luciferase reporter assays were employed to verify the bioinformatics prediction of BST2-SP1 binding. PANC1 cell proliferation and migration were analyzed following BST2 knockdown and SP1 overexpression. In comparison with HPDE6-C7 cells, all four pancreatic cancer cell lines were found to exhibit increased BST2 expression levels to varying degrees, with the highest levels observed in PANC1 cells. BST2 knockdown inhibited PANC1 cell colony formation, proliferation and migration. Additionally, SP1 was shown to bind to the BST2 promoter and could promote PANC1 cell proliferation and migration when overexpressed. However, BST2 knockdown rescued SP1 overexpression-induced PANC1 cell colony formation, proliferation and migration. In conclusion, activation of BST2 by the transcription factor SP1 was shown to accelerate pancreatic cancer cell proliferation and migration, suggesting that BST2 and SP1 may be plausible therapeutic targets in targeted therapy for pancreatic cancer.

Abstract
OBJECTIVE To evaluate the clinical diagnostic validity of carbon nanoparticle suspension (CNS) in sentinel lymph node biopsy (SLNB) for assessing lymphatic spread of early-stage cervical cancer. DESIGN A prospective study. SETTING AND POPULATION 356 cases. METHODS We enrolled 356 stage Ia2-IIa2 cervical cancer patients to undergo SLNB using CNS, followed by systematic pelvic lymphadenectomy. All lymph node specimens were assessed using conventional histopathologic ± pathologic ultrastaging analyses. MAIN OUTCOME MEASURES Sentinel lymph node detection rate (DR), clinical diagnostic validity and various related factors were analysed. RESULTS CNS identified 1456 SLNs in 325 patients. The overall SLN DR was 91.29%. A significantly higher DR was found for patients with tumours <20 mm (97.75% versus 71.91%; P < 0.001). Two patients had false-negative results. SLNB with CNS had sensitivity of 96.65%, false-negative rate (FNR) of 4.35% and negative predictive value (NPV) of 99.29%. Importantly, sensitivity (100%), NPV (100%) and FNR (0%) were improved when testing the subgroup of patients with tumours <20 mm (267 cases). There were no observed differences in DR based on pathological type or grade, stage, depth of stromal invasion, surgical approach, menopausal status or prior treatment with chemotherapy (P > 0.05). CONCLUSIONS Sentinel lymph node biopsy with CNS results in favourable DR, sensitivity and NPV for women with early-stage cervical cancer with small tumour sizes. SLNB with CNS is safe, feasible and relatively effective for guiding precise surgical treatment of early-stage cervical cancer. TWEETABLE ABSTRACT Sentinel lymph node biopsy with carbon nanoparticle suspension is safe and feasible for early-stage cervical cancer.

Abstract
Objective: To evaluate clinical effect of deproteinized bovine bone for delayed implantation after fenestration. Methods: This trial is a continuation of a prospective clinical trial. From May 2011 to February 2015 in Department of Implantology, School of Stomatology, The Fourth Military Medical University after planting division of 55 cases of maxillary teeth missing area of residual alveolar bone height ≤5 mm patients. There were 21 female and 34 male patients, their average age were (55.2±7.1) years. A total of 62 side fenestration of maxillary sinus floor lift, clinical and imaging examination, evaluation of implant retention rate, complications, peripheral soft tissue health and marginal bone resorption. Results: A total of 82 implants were followed up in 41 patients. The average follow-up time was (51.8±14.3) months (36-78 months). The follow-up rate of the maxillary sinus was 75.8% (47/62), the follow-up rate of the implant was 73.9% (82/111), and the implant survival rate was 98.8% (81/82). The bone resorption results at the implant margins were (0.64±0.63) mm (-0.28 mm, 1.47 mm) in the near and (0.49±0.73) mm (-0.51 mm, 1.21 mm) in the far, the improved hemorrhage index was 0.46±0.72, the improved plaque index was 0.60±0.87, and the keratinized mucosa width was (2.14±1.22) mm. The incidence rate of peri-implant mucositis was 28.4% (23/81) among 23 implants, and there was no complication of peri-implant inflammation. Conclusions: This study shows that under the condition of insufficient sinus ridge spacing in the maxillary posterior area, it is feasible to use bovine bone alone to remove protein for delayed implantation of maxillary sinus floor elevation by windowing, and the clinical effect is reliable.

Abstract
The swamp buffalo (Bubalus carabanensis) is mainly bred for meat, transport and rice cultivation in China and Southeast Asian countries. In the current study, we investigated the genetic diversity, maternal origin and phylogenetic relationship of swamp buffalo by analyzing 1,786 mitochondrial cytochrome b (cytb) sequences from China, Vietnam, Laos, Thailand, India and Bangladesh. Our results indicated that the swamp buffalo can be divided into two major lineages (SA and SB with the sublineages) and three rare lineages (SC, SD and SE), which showed strong geographic differentiation. The SA1 lineage represented a major domestication event, which involved population expansion. Regions III and V showed higher haplotype diversity than the other regions, indicating that the regions of Southwest China and IndoChina are potential domestication centers for the swamp buffalo. In addition, the swamp buffalo showed a closer phylogenetic relationship to tamaraw. In conclusion, our findings revealed a high level of genetic diversity and the phylogenetic pattern of the swamp buffalo.

Abstract
Five pairs of optically pure meroterpenoid enantiomers (1a/1b-5a/5b) and two known compounds (6 and 7) were isolated from Rhododendron fastigiatum. Compounds 1a/1b-5a/5b were resolved from naturally scalemic mixtures by chiral HPLC. Their structures were elucidated by spectroscopic methods, X-ray crystallographic experiments, and ECD analyses. Compounds 1a/1b, 2a/2b, 3b, 4a/4b, and 5a/5b were new meroterpenoids with different polycyclic systems. Two enantiomeric pairs (2a/2b and 3a/3b), 6, and 7 exhibited inhibitory effects on protein tyrosine phosphatase 1B (PTP1B) in vitro.

Abstract
Stature is an important quantitative trait for cattle performance, which influences herd productivity. Previous studies have reported that an SNP (AC_000171.1:g.25015640G>T, rs109815800) in Pleomorphic adenoma gene 1 (PLAG1) on chromosome 14 (CHR14) is associated with bovine stature. To validate whether rs109815800 is associated with the body height of Chinese cattle, we carried out an association analysis using 558 adult cattle samples from seven populations. Then, 1038 samples from 38 Chinese cattle breeds were used to show the geographical distribution of this variant in China. The results showed that the Q allele (G allele) increased the height of cattle. Furthermore, the frequencies of Q allele in Chinese native breeds tend to decrease from northern China to southern China, and the frequency of Q allele in two Chinese beef cattle breeds is much higher than that in another 36 Chinese local cattle breeds. Our data suggest that the prevalence of the Q allele is correlated with latitude in China.

Abstract
The influences of the position of the ytterbium-doped fiber and the parasitic lasing in the amplified spontaneous emission (ASE) pump source on the spectral properties of the random fiber laser are analyzed and discussed in this paper. The experimental results show that putting ytterbium-doped fiber in the random fiber laser's cavity and using an ASE pump source with parasitic lasing are beneficial for the generation of high-order Stokes. A near-infrared supercontinuum with 20 dB bandwidth of more than 500 nm can be generated directly from a random fiber laser, which proved that a random laser fiber cannot only works as a traditional random fiber laser, but also can be a novel, simple, low-cost, low-coherence and robust near-infrared supercontinuum generation method.

Abstract
To investigate the mtDNA variation and origin of maternal lineages in South American donkeys and to reassess the domestication of donkeys in northeast Africa, we analyzed sequences (489 bp of the D-loop) from 323 domestic donkeys sampled from Peru, Brazil, Ethiopia and Egypt. Altogether, the 323 sequences displayed 53 different haplotypes (45 in Ethiopia, 14 in Egypt, eight in Peru and six in Brazil). Among the four populations, Egyptian donkeys possessed the highest haplotype diversity (0.910 ± 0.032), followed by Brazilian donkeys (0.879 ± 0.060). The Clade I haplotypes dominated in Peruvian donkeys (65%), whereas Clade II haplotypes dominated in Brazilian donkeys (67%). Estimates of FST values showed a high genetic differentiation between Peruvian and Brazilian donkey populations (FST = 0.4066), which could be explained by the complex introduction history of South American donkeys. Phylogeographic analysis indicates that northeast Africa could be the most probable domestication center for Clade I donkeys. Analysis of molecular variance confirmed a weak genetic structure in domestic donkey populations among four continents (Europe, Asia, Africa and South America).

Abstract
Complete mitochondrial DNA D-loop sequences of 1105 individuals were used to assess the diversity of maternal lineages of cattle populations in China. In total, 250 taurine and 88 zebu haplotypes were identified. Five main haplogroups-T1a, T2, T3, T4 and T5-were identified in Bos taurus, whereas Bos indicus harbored two haplogroups-I1 and I2. Our results suggest that the distribution of T1a in Asia was concentrated mainly in the northeast region (northeast China, Korea and Japan); haplogroups T2, T3 and T4 were predominant in Chinese cattle; and T5 was sporadically detected in Mongolian and Pingwu cattle. In contrast to the widespread presence of I1, I2 was distributed only in southwestern China (Yunnan-Guizhou Plateau and the Tibet Autonomous Region) and Xinjiang Uygur Autonomous Region. This is the first time that all five taurine haplogroups and two zebu haplogroups have been found in Mongolian cattle. In addition, eight individuals in Tibetan cattle carried the Bos grunniens mtDNA type. The high mtDNA diversity (H = 0.904 ± 0.008) and the weak genetic structure among the 57 Chinese cattle breeds/populations are consistent with their complex historical background, migration route and ecological environment.

Abstract
With its vast territory and complex natural environment, China boasts rich cattle genetic resources. To gain the further insight into the genetic diversity and paternal origins of Chinese cattle, we analyzed the polymorphism of Y-SNPs (UTY19 and ZFY10) and Y-STRs (INRA189 and BM861) in 34 Chinese cattle breeds/populations, including 606 males representative of 24 cattle breeds/populations collected in this study as well as previously published data for 302 bulls. Combined genotypic data identified 14 Y-chromosome haplotypes that represented three haplogroups. Y2-104-158 and Y2-102-158 were the most common taurine haplotypes detected mainly in northern and central China, whereas the indicine haplotype Y3-88-156 predominates in southern China. Haplotypes Y2-108-158, Y2-110-158, Y2-112-158 and Y3-92-156 were private to Chinese cattle. The population structure revealed by multidimensional scaling analysis differentiated Tibetan cattle from the other three groups of cattle. Analysis of molecular variance showed that the majority of the genetic variation was explained by the genetic differences among groups. Overall, our study indicates that Chinese cattle retain high paternal diversity (H = 0.607 ± 0.016) and probably much of the original lineages that derived from the domestication center in the Near East without strong admixture from commercial cattle carrying Y1 haplotypes.

Abstract
Eight enantiomeric pairs of new meromonoterpenoids (1a/1b-8a/8b) and four known compounds (9-12) were isolated from Rhododendron nyingchiense. Their structures were established by spectroscopic methods, quantum chemical calculations, and X-ray crystallography. The enantiomeric pairs were acquired from scalemic mixtures by chiral-phase HPLC and showed diverse heterocyclic frameworks. Compounds 1a/1b possess a rare 6/7/5/5 heterocyclic system, and 2a/2b incorporate a new 6/6/3/5 heterocyclic system featuring a quinone motif. Compounds 3a/3b represent the first meroterpenoids with a 6/6/5 ring system from the Rhododendron genus. Putative biosynthetic pathways of these compounds are proposed. Compounds 1b, 2a-4a, 8a, 8b, and 11 exhibited weak inhibitory effects on PTP1B, with IC50 values ranging from 5.7 ± 0.5 to 61.0 ± 4.8 μM.
