Abstract
BACKGROUND Cancer is a life-threatening disease in humans; yet, cancer genes are frequently reported to be under positive selection. This suggests an evolutionary-genetic paradox in which cancer evolves as a secondary product of selection in human beings. However, systematic investigation of the evolution of cancer driver genes is sparse. RESULTS Using comparative genomics analysis, population genetics analysis and computational molecular evolutionary analysis, the evolution of 568 cancer driver genes of 66 cancer types were evaluated at two levels, selection on the early evolution of humans (long timescale selection in the human lineage during primate evolution, i.e., millions of years), and recent selection in modern human populations (~ 100,000 years). Results showed that eight cancer genes covering 11 cancer types were under positive selection in the human lineage (long timescale selection). And 35 cancer genes covering 47 cancer types were under positive selection in modern human populations (recent selection). Moreover, SNPs associated with thyroid cancer in three thyroid cancer driver genes (CUX1, HERC2 and RGPD3) were under positive selection in East Asian and European populations, consistent with the high incidence of thyroid cancer in these populations. CONCLUSIONS These findings suggest that cancer can be evolved, in part, as a by-product of adaptive changes in humans. Different SNPs at the same locus can be under different selection pressures in different populations, and thus should be under consideration during precision medicine, especially for targeted medicine in specific populations.

Abstract
Background China, the largest country in Asia, has a land area of approximately 9.6 million square kilometres. There are 1481 bird species (following the taxonomy of IOC World Bird List version 12.1) recorded in two zoogeographical realms, seven regions and 19 subregions in the country. From 1955 to 2017, six authoritative monographs were published, which recorded the distribution area for all bird species in China and were widely quoted by research papers and field guides. This massive amount of data could be used to address many hot topics in ornithology, biogeography and ecology. However, rapid changes in the taxonomic status and different schemes of zoogeographical regionalisation in these six monographs provided limits to the utilisation of these valuable data. New information By integrating the data from the six monographs, we presented an open-access dataset on the occurrences and residence types of all Chinese bird species in zoogeographical regions over the past 60 years. The taxonomic statuses for these species were determined following the IOC World Bird List version 12.1 and the zoogeographical regions were based on the updated scheme. These data provide valuable information for the research in bird ecology and conservation biology.

Abstract
Migratory birds spend several months in their breeding grounds in sympatry with local resident birds and relatively shorter periods of time at stopover sites. During migration, parasites may be transmitted between migratory and resident birds. However, to what extent they share these parasites remains unclear. In this study, we compared the assemblages of haemosporidian parasites in migratory, resident, and passing birds, as well as the correlations between parasite assemblages and host phylogeny. Compared with passing birds, migratory birds were more likely to share parasites with resident birds. Shared lineages showed significantly higher prevalence rates than other lineages, indicating that common parasites are more likely to spill over from the current host to other birds. For shared lineages, the prevalence was significantly higher in resident birds than in migratory birds, suggesting that migratory birds pick up parasites at their breeding ground. Among the shared lineages, almost two-thirds presented no phylogenetic signal in their prevalence, indicating that parasite transmission among host species is weakly or not correlated with host phylogeny. Moreover, similarities between parasite assemblages are not correlated with either migration status or the phylogeny of hosts. Our results show that the prevalence, rather than host phylogeny, plays a central role in parasite transmission between migratory and resident birds in breeding grounds.

Abstract
Teaching evaluation is an important measure to test the teaching quality. In order to better achieve the training objectives among international medical students based on the specific conditions of foreign students and the characteristics of Human Parasitology, a process-based assessment and evaluation system has been established for international medical students. The process assessment highlights the characteristics of assessment process, diversified forms and inquires of test questions. Following implementation of process assessment, the proportion of excellence (examination scores of 90 and higher) improved from 3.25% (10/308) to 13.09% (50/382) (t = 5.995, P < 0.001) and the proportion of good marks (examination scores of 80 to 89) increased from 18.83% (58/308) to 36.13% (138/382) (t = 7.505, P < 0.001) during the semester assessment among international medical students at five grades, while the proportion of failure in examination pass (examination scores of below 60) reduced from 12.34% (38/308) to 3.24% (10/382) (t = 7.303, P < 0.000 1), indicating that the process-based assessment and evaluation system improves the examination score of Human Parasitology among international medical students and the teaching quality of Human Parasitology.

Abstract
Negligible or negative senescence occurs when mortality risk is stable or decreases with age, and has been observed in some wild animals. Age‐independent mortality in animals may lead to an abnormally long maximum individual lifespans and be incompatible with evolutionary theories of senescence. The reason why there is no evidence of senescence in these animals has not been fully understood. Recovery rates are usually very low for wild animals with high dispersal ability and/or small body size (e.g., bats, rodents, and most birds). The only information concerning senescence for most of these species is the reported lifespan when individuals are last seen or caught. We deduced the probability density function of the reported lifespan based on the assumption that the real lifespan corresponding to Weibull or Gompertz distribution. We show that the magnitude of the increase in mortality risk is largely underestimated based on the reported lifespans with low recovery probability. The risk of mortality can aberrantly appear to have a negative correlation with age when it actually increases with increasing lifespan. We demonstrated that the underestimated aging rate for wild animals with low recovery probability can be generalizable to any aging models. Our work provides an explanation for the appearance of negligible senescence in many wild animals. Humans attempt to obtain insights from other creatures to better understand our own biology and its gain insight into how to enhance and extended human health. Our advice is to take a second glance before admiring the negligible senescence in other animals. This ability to escape from senescence is possibly only as beautiful illusion in animals.

Abstract
Objective: To analyze the correlation between loss of smell/taste and the number of real confirmed cases of coronavirus disease 2019 (COVID-19) worldwide based on Google Trends data, and to explore the guiding role of smell/taste loss for the COVID-19 prevention and control. Methods: "Loss of smell" and "loss of taste" related keywords were searched in the Google Trends platform, the data were obtained from Jan. 1 2019 to Jul. 11 2021. The daily and newly confirmed COVID-19 case number were collected from World Health Organization (WHO) since Dec. 30 2019. All data were statistically analyzed by SPSS 23.0 software. The correlation was finally tested by Spearman correlation analysis. Results: A total of data from 80 weeks were collected. The retrospective analysis was performed on the new trend of COVID-19 confirmed cases in a total of 186 292 441 cases worldwide. Since the epidemic of COVID-19 was recorded on the WHO website, the relative searches related to loss of smell/taste in the Google Trends platform had been increasing globally. The global relative search volumes of "loss of smell" and "loss of taste" on Google Trends was 10.23±2.58 and 16.33±2.47 before the record of epidemic while 80.25±39.81 and 80.45±40.04 after (t value was 8.67, 14.43, respectively, both P<0.001). In the United States and India, the relative searches for "loss of smell" and "loss of taste" after the record of epidemic were also much higher than before (all P<0.001). The correlation coefficients between the trend of weekly new COVID-19 cases and the Google Trends of "loss of smell" in the global, United States, and India was 0.53, 0.76, and 0.82 respectively (all P<0.001), the correlation coefficients with Google Trends of "loss of taste" was 0.54, 0.78, and 0.82 respectively (all P<0.001). The lowest and highest point of loss of smell/taste search curves of Google Trends in different periods appeared 7 to 14 days earlier than that of the weekly newly COVID-19 confirmed cases curves, respectively. Conclusions: There is a significant positive correlation between the number of newly confirmed cases of COVID-19 worldwide and the amount of keywords, such as "loss of smell" and "loss of taste", retrieved in Google Trends. The trend of big data based on Google Trends might predict the outbreak trend of COVID-19 in advance.

Abstract
Female common cuckoo (Cuculus canorous) predator-like “bubbling” calls distract host parental attention and reduce the egg rejection rate. Such “bubbling” calls are also frequently used to attract males and deter territorial rivals in intraspecies contact, and these calls are an ancestral character in many cuckoo species. Although hosts have had sufficient time to become familiar with this call and evolve anti-parasitic strategies, why are the hosts fooled by this “bubbling” call? We propose two hypotheses. The first hypothesis proposes that call variation reduces the opportunity for host species to correctly assess cuckoo tricks. In contrast, the second hypothesis proposes that the cost of behavior may prevent the antiparasitic strategy from evolving. In the study, we tested the prerequisites of these hypotheses, by investigating whether cuckoo calls vary during the day and testing whether the predator-like calls suppress bird activities. Based on field recordings from three different areas, we found high overlap in the calls generated during different periods. Oriental great reed warblers (Acrocephalus orientalis), a host species, did not show different responses toward the playback of female common cuckoo calls generated before noon or afternoon. Based on bird count data, we found that predator-like call playback is insufficient for suppressing bird activities. Therefore, none of the prerequisites were supported by our field data. We discuss the potential reasons for our findings and hope to inspire more research examining female cuckoo vocalizations.

Abstract
ABSTRACT The objective of the present study was to investigate the different plasma metabolites between anestrus and estrus postpartum dairy cows and to provide a theoretical basis for prevention of anestrus in dairy farm cows. In the experiment, one hundred and sixty-seven Holstein dairy cows were selected with similar age and parity. According to the concentration of β-hydroxybutyric acid, non-esterified fatty acids and glucose in plasma during 14 to 21 days in milk, all dairy cows were determined as having a status of energy balance. According to the results of clinical symptom, rectal and B ultrasound examination at 60 to 90 days postpartum, these cows were divided into twenty estrus and twenty-four anestrus group, other dairy cows were removed. 1H nuclear magnetic resonance technology was utilized to detect the plasma metabolites changes and screen different plasma metabolites between anestrus and estrus cows. Ten different metabolites including alanine, glutamic acid, asparagine, creatine, choline, phosphocholine, glycerophosphocholine, low-density lipoprotein, and very-low-density lipoprotein were significantly decreased in anestrous cows compared with estrous cows. Metabolic pathway analyses indicated that differential metabolites were primarily involved in amino acid and glycerophospholipid metabolism. These metabolites and their enrichment pathways indicate that reduced steroid hormone synthesis precursors result in lower levels of estradiol and progesterone and cause anestrus in negative energy balance. These data provide a better understanding of the changes that may affect estrus of postpartum dairy cows at NEB status and lay the ground for further research.

Abstract
BACKGROUND Visceral function localization of the brain is very complex. For many years, people have been actively exploring the neural mechanism regulating visceral and substance metabolism, clarifying the complex relationship between the brain and peripheral nervous system related to the regulation of visceral activity, and analyzing its complex neural pathways. The brain is the advanced center of visceral function regulation. As an advanced center for substance metabolism and visceral regulation, the hippocampus is crucial for regulating visceral function. The liver is the core organ of material metabolism, and its afferent signals are mainly projected to the Nucleus of the solitary tract(NTS) through vagus nerve, and then they are projected to the hypothalamus and limbic system. MATERIALS AND METHODS We placed a stereotaxic instrument on the head of each rat and performed craniotomy to open a window above the left hippocampus. We used gold-plated tungsten electrodes to monitor hippocampal neuronal discharges. Grounding was achieved using screws and silver wire. We electrically stimulated the liver branch of the vagus nerve and observed changes in hippocampal neuron discharges using a biological method; in this way, we identified hepatosensitive hippocampal region. We injected FluoroGold into this region and related brain areas. After 3 days, the rats were sacrificed and perfused; the hippocampi were fixed, dehydated, frozen, sectioned, and subjected to fluorescence microscopy. RESULTS Nerve discharge frequency and amplitude significantly increased in the hippocampal CA3 region (AP: -4.9, ML: -5.1, DV: -5.0 mm). After FluoroGold was injected into the left hepatosensitive region in the hippocampus, labeled cells were found in the contralateral hippocampus, ipsilateral piriform cortex (PC), locus coeruleus (LC) and bilateral lateral hypothalamus (LHA); fluorescence in the ipsilateral hypothalamus was stronger than that of the contralateral hypothalamus. FluoroGold was injected into the LHA, PC, and LC; no labeled cells were found in the hippocampal CA3 region or in the control group. CONCLUSIONS The hippocampal CA3 area of rats may contain a hepatosensitive region that plays important roles in the regulation of liver and other organ function. These region may receive input from the LHA, PC, and LC.

Abstract
Dozens of surrogates have been used to reflect the rate of aging in comparative biology. For wild organisms, the maximum reported life span is often considered a key metric. However, the connection between the maximum reported life span for a single individual and the aging rate of that species is far from clear. Our objective was to identify a pragmatic solution to calculate the aging rate from the maximum reported life span of wild birds. We explicitly linked the maximum reported life span to the aging process by employing a Weibull distribution and calculating the shape parameter in this model, which reflects the change in mortality across ages and be used as a surrogate for the aging rate. From simulated data, we demonstrated that the percentile estimator is suitable for calculating the aging rate based on the maximum reported life span. We also calculated the aging rate in 246 bird species based on published information from EURING and tested its relationship with body mass. Our study constitutes a new approach for using maximum reported life span in aging research. The aging rate calculated in the study is based on numerous assumptions/prerequisites and can be improved as more is learned about these assumptions/prerequisites.

Abstract
Anestrus is essential to an unsuccessful pregnancy in dairy cows. One of the many factors that influences anestrus is the inactive ovary. To characterize in detail the plasma metabolic pro- file, anestrus cows suffering from inactive ovaries were compared with those with natural estrus. The Holstein cows 60 to 90 day postpartum in an intensive dairy farm were assigned into inactive ovaries groups (IO, n=20) and natural estrus group (CON, n=22) according to estrus signs and rectal palpation of ovaries. Plasma samples from two groups of cows were collected from the tail vein to screen differential metabolites using gas chromatography/mass spectrometry (GC/MS) techniques and multivariate statistical analysis and pathways. The results showed that 106 compounds were screened by GC/MS and 14 compounds in the IO group were decreased by analyzing important variables in the projection values and p values of MSA.Through pathway analysis, 14 compounds, mainly associated with carbohydrate metabolism and amino acid meta- bolism, were identified to results in IO, which may seriously affect follicular growth. Metabolo- mics profiling, together with MSA and pathway analysis, showed that follicular growth and development in dairy cows is related to carbohydrate and amino acid metabolism by a single or multiple pathway(s).

Abstract
ABSTRACT Ketosis can seriously impair cow performance. This study detected changes in prepartum blood metabolic parameters for predicting postpartum ketosis occurrence in dairy cows. Body condition score (BCS) was assessed before and after delivery. Blood samples of 63 cows were collected from 10 days before calving to 10 days after calving to measure metabolic parameters including β-hydroxybutyric acid (BHBA), non-esterified fatty acid (NEFA), glucose (GLU), total bilirubin (TBIL), direct bilirubin (DBIL), indirect bilirubin (IBIL), total protein (TP), albumin (ALB), globulin (GLO), alanine aminotransferase (ALT), and aspartate aminotransferase (AST). There was a postpartum subclinical ketosis incidence of 42.25%. Compared with prepartum, plasma, levels of BHBA, AST, and NEFA significantly increased postpartum, and prepartum AST (R=0.57) and NEFA (R=0.45) showed a significant positive correlation with ketosis postpartum. Plasma GLU level significantly decreased postpartum and was significantly negatively correlated with ketosis (R=-0.21). Receiver operating characteristic curve analysis revealed prepartum BSC < 2.88, and prepartum plasma AST > 68.0 U/L, GLU < 3.97mmol/L, NEFA > 0.27mmol/L, and BHBA > 0.43mmol/L, indicating a high risk of subclinical ketosis postpartum. These levels can be used as risk indicators to predict the occurrence of subclinical ketosis in postpartum cows.

Abstract
Abstract
Background
Systematic COronary Risk Evaluation (SCORE) has been proposed to assess the 10-year risk of fatal cardiovascular diseases, with distinction between low-risk and high-risk countries. Risk modifiers are recommended to further improve risk reclassification, for example the coronary artery calcium (CAC) score. CAC scoring can significantly improve risk prediction for coronary events based on outcome studies. The impact of CAC scoring on risk classification in a middle-aged cohort from a low-risk country in comparison to SCORE is unknown.
Purpose
To assess presence of coronary calcification and association with cardiovascular risk factors and related SCORE risk in a middle-aged population from a low risk country.
Methods
Coronary calcification and classical cardiovascular risk factors were analyzed in 4,083 Dutch participants aged 45–60 years (57.9% women) without a known history of coronary artery disease in the population-based ImaLife (Imaging in Lifelines) study. Individuals underwent non-contrast cardiac CT using third generation dual-source CT. Coronary artery calcium (CAC) scores were quantified using Agatston's method. Age- and sex- specific distributions of CAC categories (0, 1–99, 100–299, ≥300) and percentiles were assessed. Distribution of CAC categories was compared to SCORE risk categories (<1%, ≥1% to 5%, and ≥5%) for low risk countries. Relationship between risk factors and CAC presence was evaluated by logistic regression models. Population attributable fractions (PAFs) of classical risk factors for CAC presence were estimated to investigate potential prevention strategy.
Results
CAC was present in 54.5% of men and in 26.5% of women. With increasing age, an increasing percentage had a positive CAC score, from 38.1% of men and 15.2% of women at age 45–49 years, to 66.9% of men and 36.6% of women at age 55–60. Mean SCORE was 1.3% (2.0% in men, 0.7% in women). In SCORE risk <1%, 32.7% of men and 17.1% of women had CAC. In men with SCORE risk ≥5% (0.1% of women), 26.9% had no CAC. Overall PAF for presence of CAC of the classical risk factors was 18.5% in men and 31.4% in women. PAF was highest for hypertension (in men 8.0%, 95% CI 4.2–11.8%; in women 13.1%, 95% CI 7.9–18.2%) followed by hypercholesterolemia and obesity.
Conclusion
In this middle-aged Dutch cohort, slightly over half of men and a quarter of women had any CAC. With age there was an increase in CAC presence for both sexes. Only a minor proportion of CAC presence was attributable to classical risk factors. This provides further support that CAC scoring can impact risk classification in a middle-aged population of a low-risk country.

Abstract
Abstract
Background
The distribution of coronary artery calcium (CAC) across the coronary system increases the ability to predict coronary events compared to traditional CAC scoring alone. Reference values for regional distribution of CAC by age and sex are not yet available for a general European population.
Purpose
To investigate the distribution of CAC across the coronary arteries by age and sex in the population-based ImaLife study.
Methods
ImaLife is part of Lifelines, a multi-generational, prospective cohort study with over 167,000 participants from the northern Netherlands. From 2017–2019, 5,531 participants aged 45–84 years underwent non-contrast cardiac CT using third-generation dual-source CT. Total and vessel-specific CAC scores (Agatston's method) were acquired semi-automatically using dedicated software. Participants with a positive CAC score were classified into three groups: total CAC score 1–100, 101–300 and >300. The diffusivity index (equation: 1 – [highest one-vessel CAC/total CAC]) was calculated. The diffusivity index is an expression of the relative distribution of CAC across the coronary arteries. Data were analyzed for the whole population and by sex and age groups. Mann-Whitney U test was used to analyze the diffusity index in men and women. Kruskal-Wallis H tests were performed to test the diffusivity index in different age groups.
Results
In total 2,376 men (mean age 56.4±7.7 years) and 3,155 women (mean age 56.0±7.5 years) were analyzed. In participants with CAC, 1, 2, 3 or 4 vessels were affected in 523 (22.0%), 560 (17.7%), 371 (15.6%) and 257 (8.1%) of men, respectively, and in 385 (16.2%), 175 (5.5%), 185 (7.8%) and 81 (2.6%) of women, respectively (P<0.001). The number of 1, 2, 3 or 4 vessels affected were significantly different by age (p<0.001). In age category 45–49 years, CAC in 1, 2, 3, and 4 vessels was present in 60.1%, 21.6%, 15.5%, and 2.9%, respectively; for age 74+ years, these percentages were 19.3%, 19.3%, 31.1% and 30.3%, respectively. The number of affected vessels were significantly different in different CAC categories (p<0.001), see Figure. More vessels were affected in higher CAC categories. The median diffusivity index was higher in men than in women (0.10 (IQR: 0–0.36) vs 0 (IQR: 0–0.24), p<0.001) and increased by increasing age. For age categories of 45–49, 50–54, 55–59,60–64, 65–69, 70–74, and >74 years, diffusivity indexs were 0 (IQR: 0–0.12), 0 (IQR: 0–0.22), 0.02 (IQR: 0–0.28), 0.10 (IQR: 0–0.35), 0.16 (IQR: 0–0.42), 0.20 (IQR: 0–0.44), and 0.28 (IQR: 0.03–0.45) (p<0.001).
Conclusions
In this Dutch population-based study, male participants had higher prevalence of CAC with higher number of involved vessels, and a higher diffusivity index compared to women. For both sexes, involved vessels and diffusivity index increased with age. The reference values of this regional distribution of CAC in a European population can assist in risk categorization of cardiovascular events.

Abstract
On August 6, 2015, a male infant with ectodermal dysplasia/skin fragility syndrome at 6 hours of birth was admitted to the Burn Department of Tongren Hospital of Wuhan University & Wuhan Third Hospital. The ulcerous skin tissue in thoracic area was harvested. The histopathological change of wound tissue was observed with hematoxylin-eosin staining. The result showed that the epidermal muscle cell layer was slightly released, there were bullae under the epidermis, the dermal papilla layer disappeared, and a small amount of inflammatory cells infiltrated in the dermis. The expression of plakophilin 1 (PKP1) in wound tissue was observed with immunohistochemical staining. The result showed that the PKP1 expression was completely absent. The PKP1 gene mutation site was identified by target sequencing. The result showed that the PKP1 gene had a homozygous mutation at intron (PKP1: c.203-1G>A). Most of the wounds of the pediatric patient healed after 35 days of treatment, with many scattered residual wounds visible, and new blisters and skin lesions continue to appear.

Abstract
Inducible co-stimulator-positive (ICOS) and programmed cell death 1-positive (PD-1) are important markers for follicular helper T cells (Tfh); however, their roles and clinical values in ulcerative colitis (UC) remain unknown. In this study, we recruited 68 UC patients and 34 healthy controls. Circulating ICOS+ , PD-1+ and ICOS+ PD-1+ Tfh subsets were analyzed by flow cytometry. Twelve active UC patients achieving remission after treatment with 5-aminosalicylic acid were followed-up and Tfh subset changes were analyzed. Serum immunoglobulin (Ig)G, C-reactive protein (CRP), interleukin (IL)-4 and IL-21 levels and B cell subsets were analyzed and Mayo scores were calculated. Correlation analyses were performed between Tfh subsets and the clinical indicators. Receiver operating characteristic (ROC) curves were generated to evaluate the efficiency of Tfh subsets for disease monitoring. We found that levels of ICOS+ , PD-1+ and ICOS+ PD-1+ Tfh cells were significantly increased in active UC and significantly decreased when achieving clinical remission. Activated ICOS+ PD-1+ Tfh cells were positively correlated with serum CRP and Mayo scores. Furthermore, ICOS+ PD-1+ Tfh cells were significantly correlated with circulating new memory B cells and plasmablasts, as well as serum IgG, IL-4 and IL-21. ROC analyses showed that when ICOS+ PD-1+ Tfh cells were used in combination with PD-1+ Tfh cells, the diagnostic efficacy in distinguishing active UC from stable remission patients was higher than that of any one used alone, with area under curve (AUC) value 0·931. Our findings suggest that increased ICOS+ PD-1+ Tfh cells are associated with the activation of B cells in the pathogenesis of UC, and may be a potential biomarker for UC disease monitoring.

Abstract
Animals keep a safe distance to humans and thus humans rarely physically encounter wild animals. However, birds have been known to feed from the hand of humans. Such behaviour must reflect the trade-off between acquisition of food and the risk of being captured by a potential predator feeding from the hand. Relying on YouTube, an international video-sharing platform, we found 36 European bird species recorded feeding from the hand of humans. We compared ecological traits between these species and all other 490 European bird species, which were not recorded as feeding from a human hand. We found that species with a large number of innovative behaviours, a higher rate of introduction success, larger breeding range, larger population size, and urban tolerance have a higher probability of feeding from the hand of a human. These associations were also supported after control for the similarity among taxa due to common phylogenetic descent. In conclusion, these findings suggest that frequent feeding from the hand of a human results in the transition from natural environments to novel urbanized environments with consequences for population size increasing and range expansion.

Abstract
Vocal individual identification has been demonstrated in many animals, with discriminant function analysis (DFA) and spectrographic cross-correlation (SPCC) being the two most frequent methods. Successful vocal individual identification requires high among-individual differences and within-individual stability over time for vocal features. Lack of vocal individual identification is common in songbirds with complex songs, and most vocal individual identification studies are made in bird species with simple vocalizations. Here, we applied vocal individual identification with the two methods on a songbird, green-backed flycatcher Ficedula elisae. We based its complex songs by division into first, second, and third phrases. DFA resulted in a correct distinction rate of 94.5 % between one first-phrase type and another. SPCC similarity was significantly higher within than among types for first and second phrases, respectively. For first-phrase types with recordings from different days during a breeding season, the correct DFA rate was 87.1 %. SPCC similarity within type changed significantly among days, but was still significantly higher than that among types. In conclusion, first phrases of the complex songs met the two requirements and could be effectively used for vocal individual identification in this species. This study filled a gap in vocal individual identification in birds with complex songs.

Abstract
The aerosol liquid water content (ALWC) of submicron particles (PM1) was calculated in this work by three methods based on the aerosol physical and chemical properties measurement campaigns in winter in Beijing, including (a) the PM1 volume difference between the ambient and dry states by applying the particle number size distribution and particle hygroscopicity measurement; (b) the thermodynamic equilibrium model (ISORROPIA II) based on the chemical composition; and (c) the κ-Köhler theory of chemical composition with a volume mixing scheme. The three methods agreed well with reasonable uncertainties. The ALWC showed an exponential trend depending on the relative humidity (RH), and an abundant ALWC was also favored by the high PM1 mass loading. The contribution of different chemical component to the ALWC was evaluated by the κ-Köhler method, which revealed that during the measurement, the inorganics and organics could contribute to ~80% and ~20%, respectively, under ambient RH conditions, with the largest contributor of ammonium nitrate. When the RH was above 85%, the mass concentration of ALWC was comparable to, or even larger than, that of the dry PM1.

Abstract
Abstract
Background
Coronary artery calcium (CAC) scoring is a promising tool for cardiovascular risk classification. Population-based reference values are important for the clinical interpretation of CAC scores.
Purpose
To establish standards of CAC distributions by age and gender in an unselected Dutch population, which can be used to determine reference values.
Methods
ImaLife (Imaging in Lifelines) is a computed tomography (CT) based substudy of the Lifelines cohort, with a primary aim to establish reference values of imaging biomarkers for early stages of coronary artery disease in adults (above 45 years old). In total, 12,000 participants will be enrolled from an unselected adult population in the northern Netherlands for CAC scoring with third generation dual-source CT. CAC is quantified with dedicated commercial software using the Agatston method.
Results
Included so far were 3,702 participants (57.5% females, mean age 54 years, range 45–82 years). CAC was present in 39.2% of participants, with a higher prevalence of CAC in men (55.3%) than in women (27.3%). CAC scores increased with increasing age in both genders. The percentiles of CAC scores by age and gender groups are summarized in the table.

Conclusion
This preliminary result presents CAC distribution by age and gender in a middle-aged unselected Dutch population. Compared with the Heinz Nixdorf Recall study, CAC scores in our cohort for both genders were lower in the 5-year age groups between 45 and 64 years. Based on the overall data, expected within 2 years, reference values of CAC for the Dutch population can be established.

Abstract
Abstract
Background
Low-dose chest computed tomography (CT) is increasingly used in lung cancer screening. The heart is inherently visualized on chest CT. Coronary artery calcium (CAC) identified on chest scans has predictive value for risk of cardiovascular disease. There is discussion whether non-ECG-triggered chest CT is reliable for CAC scoring.
Purpose
To investigate the agreement between chest CT and ECG-triggered cardiac CT in CAC identification and risk classification.
Methods
We included 1000 ImaLife participants who underwent a cardiac scan immediately followed by a non-ECG triggered chest scan. Third-generation dual-source CT and dedicated software were used for scan acquisition and CAC measurement. Chest scans were analyzed after cardiac scans with an interval of at least a month and in a different order. To ensure a comparable prevalence of CAC with previous studies and adequate samples in CAC strata, after the inclusion of the 500th consecutive participants with zero CAC, only participants with >0 CAC based on dedicated cardiac CT were included. CAC scores were divided into four risk strata: 0, 1–99, 100–399, 400. Kappa was used to assess agreement in CAC identification (0 versus >0) and risk classification.
Results
The mean age was 54 years (range 45–77), 42.5% were women, average body mass index (BMI) was 26.1kg/m2. Compared with dedicated cardiac CT, non-ECG triggered chest CT had an accuracy of 0.97, sensitivity of 0.96 and specificity of 0.99 for identifying CAC, and agreement between scans was very high (kappa 0.95) for CAC presence. In terms of CAC risk strata, chest CT had a very high agreement with cardiac CT (kappa 0.95). Total misclassification rate of CAC strata was 6.5%, with most misclassified cases shifting one risk category downward (55/65, 85%). BMI of discordant pairs was significantly higher than concordant pairs, while no difference in heart rate was found.
Conclusion
Non-ECG triggered chest CT may be reliably used for CAC identification and risk classification since chest CT has very high agreement with dedicated cardiac CT results.

Abstract
Objective: To investigate the expressions of vascular endothelial growth factor (VEGF), hypoxia inducible factor-1 alpha (HIF-1α), and epidermal growth factor receptor (EGFR) in different morphological regions of Marjolin ulcer and their clinical relationship with angiogenesis. Methods: From January 2012 to December 2017, the patients admitted to our hospital who met the inclusion criteria were selected, including 92 patients with Marjolin ulcer [56 males and 36 females, aged (55±15) years], 100 patients with chronic non-cancerous skin ulcer [59 males and 41 females, aged (51±16) years], and 100 patients performed with other skin-related surgery [58 males and 42 females, aged (52±15) years], and they were enrolled into Marjolin ulcer group (MU), chronic non-cancerous ulcer group (CNU), and other skin surgery group (OSS) respectively. The etiology, pathogenic site, ulcer diameter, and course of patients in group MU were retrospectively analyzed. Ulcer tissue specimens from patients of group MU and group CNU and specimens of normal skin tissue attached to the tissue resected during operation from patients of group OSS were collected. The expressions of VEGF, HIF-1α, EGFR, and CD34 in the above-mentioned tissue and the surrounding normal skin, ulcer, epitheliomatous hyperplasia, and canceration areas in Marjolin ulcer tissue were detected by immunohistochemical method, and the positive expression rate and protein expression level were calculated. Data were processed with Pearson chi-square test, Mann-Whitney U test, Bonferroni method, and Bonferroni correction, and Spearman correlation analysis was used to analyze the relationship among the total protein expression levels. Results: In group MU, burns accounted for 91.3% (84/92) of the causes of patients, 44.6% (41/92) of the patients had tumors in the lower extremities, 62.0% (57/92) of the patients had skin ulcer diameter of 2.1-5.0 cm, and 75.0% (69/92) of the patients had a course of disease of more than 20 years. The positive rates of VEGF, HIF-1α, and EGFR in ulcer tissue of patients in group CNU were 41.0% (41/100), 77.0% (77/100), and 83.0% (83/100), respectively, significantly higher than those of normal skin tissue of patients in group OSS [12.0% (12/100), 45.0% (45/100), and 67.0% (67/100), χ(2)=21.589, 21.522, 6.827, P<0.01]. The positive rates of VEGF, HIF-1α, and EGFR in ulcer tissue of patients in group MU were 91.3% (84/92), 100.0% (92/92), and 100.0% (92/92), respectively, which were significantly higher than those in corresponding tissue of patients in group CNU and group OSS (χ(2)=53.372, 24.772, 17.159; 120.543, 72.777, 36.661, P<0.01). In ulcer tissue of patients in group MU, the positive expression rates of VEGF in ulcer, epitheliomatous hyperplasia, and canceration areas were significantly higher than the rate in surrounding normal skin area (χ(2)=87.120, 42.368, 89.624, P<0.01); the positive expression rates of VEGF in canceration and ulcer areas were significantly higher than the rate in epitheliomatous hyperplasia area (χ(2)=22.586, 16.060, P<0.01). In ulcer tissue of patients in group MU, the positive expression rates of EGFR in ulcer, epitheliomatous hyperplasia, and canceration areas were significantly higher than the rate in surrounding normal skin area (χ(2)=21.679, 27.600, 27.600, P<0.01), but the positive expression rates of HIF-1α in four morphological areas were similar (χ(2)=3.008, P>0.05). In ulcer tissue of patients in group MU, the protein expression levels of VEGF and CD34 in ulcer, epitheliomatous hyperplasia, and canceration areas were significantly higher than those in surrounding normal skin area (Z=-6.765, -6.819; -6.765, -6.640; -6.765, -6.819, P<0.01), the protein expression levels of VEGF and CD34 in epitheliomatous hyperplasia area were significantly lower than those in ulcer area (Z=-4.484, -5.266, P<0.01), and the protein expression levels of VEGF and CD34 in canceration area were significantly higher than those in ulcer area (Z=-6.427, -6.723, P<0.01) and epitheliomatous hyperplasia area (Z=-6.427, -6.462, P<0.01). In ulcer tissue of patients in group MU, the protein expression levels of HIF-1α and EGFR in ulcer, epitheliomatous hyperplasia, and canceration areas were significantly higher than those in surrounding normal skin area (Z=-6.819, -6.393; -6.819, -6.393; -6.819, -6.393, P<0.01), the protein expression levels of HIF-1α and EGFR in ulcer area were significantly lower than those in epitheliomatous hyperplasia and canceration areas (Z=-6.118, -5.638; -6.640, -6.393, P<0.01), and the protein expression levels of HIF-1α and EGFR in canceration area were significantly higher than those in epitheliomatous hyperplasia area (Z=-6.558, -6.819, P<0.01). In ulcer tissue of patients in group MU, the total protein expression levels of VEGF, HIF-1α, and EGFR were significantly positively correlated with the total protein expression level of CD34 (r=0.772, 0.415, 0.502, P<0.01) respectively; the total protein expression level of EGFR was significantly positively correlated with that of HIF-1α (r=0.839, P<0.01), both of which were significantly positively correlated with the total protein expression level of VEGF (r=0.531, 0.440, P<0.01) respectively. Conclusions: The expressions of VEGF, HIF-1α, and EGFR are the highest in Marjolin ulcer canceration area, and EGFR may promote angiogenesis through HIF-1α or directly increasing the expression of VEGF.

Abstract
ATP-sensitive potassium channels (KATP) may mediate a potential neuroprotective role in Alzheimer's disease (AD). Given that exposure to Aβ1-42 in cultured primary cholinergic neurons for 72 h significantly upregulates the expression of KATP subunits Kir6.2/SUR1, we aim to study the underlying signal transduction mechanisms that are involved in Aβ1-42-induced upregulation of KATP subunits Kir6.2/SUR1. In the present study, we first identified the primary cultured rat cortical and hippocampal neurons using immunocytochemistry. 0.5 μM NF-κB inhibitor SN-50, 2 μM p38MAPK inhibitor SB203580 or 2 μM PKC inhibitor Chelerythrine chloride (CTC) were then added in three separate groups, followed by 2 μM Aβ1-42 30 min later in all 3 groups. Western Blot was performed 72 h later to detect the expression of KATP subunits Kir6.2/SUR1. We found that Aβ1-42 significantly increased the level of KATP subunits Kir6.2/SUR1 expression at 72 h when compared with the control group ( p < 0.05). However, when compared with the Aβ1-42 group, the level of KATP subunits Kir6.2/SUR1 expression at 72 h significantly decreased in the SN50 + Aβ1-42 group, SB203580 + Aβ1-42 group, and the CTC + Aβ1-42 group ( p < 0.05). Our findings suggest that the NF-κB, p38 MAPK, and PKC signal pathways are partially involved in the upregulation of KATP subunits Kir6.2/SUR1 expression induced by Aβ1-42 cytotoxicity in neurons, which supports a potential theoretical basis of targeting these signal pathways in the treatment of AD.

Abstract
Urbanization effects on living organisms are spatially heterogeneous. Here we quantified the abundance of birds per tree in forested urban and rural habitats for 85,829 trees mainly in China and Europe. A population model was based on the assumption that: 1) birds have a normally distributed habitat preference; 2) an increase in population size linked to the habitat preference; 3) a population size dependent on the habitat preference; and 4) the removal of a certain fraction of individuals giving rise to extinction. We tested for large-scale differences in the impact of urbanization on the frequency distribution of the difference in abundance between urban and rural habitats in China and parts of Europe. The difference in the frequency distribution of urban population density of birds in trees minus rural population density of birds in trees in China and Europe was statistically significant, suggesting that the abundance of birds differed between trees in urban and rural habitats, but more so in China than in Europe. We hypothesize that more pronounced differences in China than in Europe may have arisen due to the Four Pests Campaign in 1958-1962 that resulted in death of hundreds of millions of birds (mainly tree sparrows Passer montanus, but also numerous other less common species that were starting to become urbanized around 1960). Species that were less common in 1960 could not sustain reductions in population size in urban areas and hence these species are still rare or absent in urban areas today 60 years later.

Abstract
Objective: To evaluate the long term change of the cervical sagittal profile in adolescent Chiari malformation type Ⅰ (CMI)/syringomyelia undergoing posterior fossa decompression (PFD) and to further evaluate the correlation between the syrinx resolution and cervical sagittal profile. Methods: A retrospective radiographic study was performed in 32 adolescents undergoing PFD for CMI/syringomyelia from October 2011 to August 2015 with a minimum 2-year follow-up. There were 23 males and 9 females, with a mean age of (13.7±2.8) years (range, 10-16 years). The following parameters including upper cervical angle (C(0)-C(2)), lower cervical angle (C(2)-C(7)), sagittal balance (C(2)-C(7)SVA), cervical curvature index (CCI), syrinx size and length were compared preoperatively and at the last follow-up. The correlation of syrinx resolution and cervical sagittal parameters were further analyzed with Pearson correlation analysis. Results: All patients received a followed-up for 2.0-6.5 years [mean (3.9±1.1) years]. The lower cervical angle and CCI were-29.8°±11.4° and 29.1%±7.1% at the last follow-up, respectively, which were significantly higher than those before surgery (-15.2°±8.8°, 13.4%±4.2%)(t=2.917, 2.902, both P<0.05). The syrinx size and length were also obviously decreased at the last follow-up. No significant difference was found in the upper cervical angle and C(2)-C(7)SVA before operation and at the last follow-up (t=0.302, 0.871, both P>0.05). There were significantly positive correlations between the differences of syrinx width and the lower cervical angle, and the CCI before and after surgery (r=0.611, 0.652, both P<0.05). Significantly positive correlations were also observed between the differences of syrinx length and the lower cervical angle, and the CCI before and after surgery (r=0.504, 0.514, both P<0.05). Conclusions: The cervical lordosis can be restored after PFD in adolescents with CMI/syringomyelia. The resolution of syrinx may play an important role in restoring the cervical sagittal alignment.

Abstract
BACKGROUND Gene and genome duplication play important roles in the evolution of gene function. Compared to individual duplicated genes, gene clusters attract particular attention considering their frequent associations with innovation and adaptation. Here, we report for the first time the expansion of the apolipoprotein D (ApoD) ligand-transporter genes in a cluster manner specific to teleost fishes. RESULTS Based on comparative genomic and transcriptomic analyses, protein 3D structure comparison, positive selection detection and breakpoints detection, the single ApoD gene in the ancestor expanded into two clusters following a dynamic evolutionary pattern in teleost fishes. Orthologous genes show conserved expression patterns, whereas lineage-specific duplicated genes show tissue-specific expression patterns and even evolve new gene expression profiles. Positive selection occurred in branches before and after gene duplication, especially for lineage-specific duplicated genes. Cluster analyses based on protein 3D structure comparisons, especially comparisons of the four loops at the opening side, show gene duplication-segregating patterns. Duplicated ApoD genes are predicted to be associated with forkhead transcription factors and MAPK genes. ApoD clusters are located next to the breakpoints of genome rearrangements. CONCLUSIONS Here, we report the expansion of ApoD genes specific to teleost fishes in a cluster manner for the first time. Neofunctionalization and subfunctionalization were observed at both the protein and expression levels after duplication. Evidence from different aspects-i.e., abnormal expression-induced disease in humans, fish-specific expansion, predicted associations with forkhead transcription factors and MAPK genes, specific expression patterns in tissues related to sexual selection and adaptation, duplicated genes under positive selection and their location next to the breakpoints of genome rearrangements-suggests the potentially advantageous roles of ApoD genes in teleost fishes. The cluster expansion of ApoD genes specific to teleost fishes provides thus an ideal evo-devo model for studying gene duplication, cluster maintenance and new gene function emergence.

Abstract
Objective: To introduce a self-developed bone dust collector designed by the authors and evaluate its efficiency in mastoid obliteration following mastoidectomy. Methods: Consecutive patients, from April 2017 to March 2018, who prepared to receive mastoidectomy were randomly divided into two groups, and in each group the bone dust was harvested by self-developed bone dust collector or by conventional used method respectively in mastoidectomy. The amount of the harvested bone dust and the time consumed in the collecting procedure were compared between two groups. The infection of the bone dust after mastoid obliteration was also evaluated during follow up. Results: 33 patients were recruited in bone dust collector group, and 31 patients in conventional method group.There is no significance of difference between two groups in sex ratio, age and pneumatization of mastoid cells (P>0.05 for all). The median amount of bone dust harvested by bone dust collector was significantly larger than that collected by conventional method (1.8 g vs 1.1 g, P<0.05). The median time spent in bone dust collector group was significantly shorter than that spent in conventional method group (4 minutes vs 6 minutes, P<0.05). No bone dust infection was found in the follow-up in all patients. Conclusion: The present self-developed bone dust collector is a easy and useful apparatus which can significantly improve the efficiency of collecting bone dust in mastoidectomy.

Abstract
As species serve as basic units of study in many fields of biology, assessments of species limits are fundamental for such studies. Here, we used a multilocus dataset and different coalescent-based methods to analyze species delimitation and phylogenetic relationships in the Brownish-flanked Bush Warbler Horornis fortipes complex, which is widespread in the Sino-Himalayan region. We also examined the vocal and morphometric divergence within this complex. Our genetic results suggested that Horornis fortipes is composed of at least three independently evolving lineages, which diverged 1.1-1.8 million years ago. However, these lineages have hardly diverged in song or morphometrics and only very slightly in plumage. Our result indicate that there are three incipient species in Horonis fortipes complex diverged in central Himalayas and Hengduan Mountains, but not between the continent and Taiwan island.

Abstract
Lithium-oxygen (Li-O2) batteries have attracted much attention owing to the high theoretical energy density afforded by the two-electron reduction of O2 to lithium peroxide (Li2O2). We report an inorganic-electrolyte Li-O2 cell that cycles at an elevated temperature via highly reversible four-electron redox to form crystalline lithium oxide (Li2O). It relies on a bifunctional metal oxide host that catalyzes O–O bond cleavage on discharge, yielding a high capacity of 11 milliampere-hours per square centimeter, and O2 evolution on charge with very low overpotential. Online mass spectrometry and chemical quantification confirm that oxidation of Li2O involves transfer of exactly 4 e–/O2. This work shows that Li-O2 electrochemistry is not intrinsically limited once problems of electrolyte, superoxide, and cathode host are overcome and that coulombic efficiency close to 100% can be achieved.

Abstract
BACKGROUND Few studies have reported the clinical features, complications and predictors of Kasabach-Merritt phenomenon (KMP) associated with Kaposiform haemangioendothelioma (KHE). OBJECTIVES To determine the clinical characteristics present at diagnosis and to identify features that may aid clinicians in managing KHE. METHODS We conducted a cohort study of 146 patients diagnosed with KHE. RESULTS KHE precursors or lesions were present at birth in 52·1% of patients. In 91·8% of patients, lesions developed within the first year of life. The median age at diagnosis of KHE was 2·3 months (interquartile range 1·0-6·0). The extremities were the dominant location, representing 50·7% of all KHEs. Among KHEs in the cohort, 63·0% were mixed lesions (cutaneous lesions with deep infiltration). Approximately 70% of patients showed KMP. A KHE diagnosis was delayed by ≥ 1 month in 65·7% of patients with KMP. Patients with KMP were more likely to have major complications than patients without KMP (P = 0·023). Young age (< 6 months), trunk location, large lesion size (> 5·0 cm) and mixed lesion type were associated with KMP in a univariate analysis. In the multivariate analysis, only age [odds ratio (OR) 11·9, 95% confidence interval (CI) 4·07-34·8; P < 0·001], large lesion size (OR 5·08, 95% CI 2·24-11·5; P < 0·001) and mixed lesion type (OR 2·96, 95% CI 1·23-7·13; P = 0·016) were associated with KMP. CONCLUSIONS Most KHEs appeared before 12 months of age. KHEs are associated with various major complications, which can occur in combination and develop early in the disease process. Young age, large lesion size and mixed lesion type are important predictors of KMP.

Abstract
Background The burden of cancer in China is high, and it is expected to further increase. Information on cancers attributable to potentially modifiable risk factors is essential in planning preventive measures against cancer. We estimated the number and proportion of cancer deaths and cases attributable to ever-smoking, second-hand smoking, alcohol drinking, low fruit/vegetable intake, excess body weight, physical inactivity, and infections in China, using contemporary data from nationally representative surveys and cancer registries. Methods The number of cancer deaths and cases in 2013 were obtained from the National Central Cancer Registry of China and data on most exposures were obtained from the China National Nutrition and Health Survey 2002 or 2006 and Global Adult Tobacco Smoking 2010. We used a bootstrap simulation method to calculate the number and proportion of cancer deaths and cases attributable to risk factors and their corresponding 95% confidence intervals (CIs), allowing for uncertainty in data. Results Approximately 718 000 (95% CI 702 100-732 200) cancer deaths in men and 283 100 (278 800-288 800) cancer deaths in women were attributable to the studied risk factors, accounting for 52% of all cancer deaths in men and 35% in women. The numbers for incident cancer cases were 952 500 (95% CI 934 200-971 400) in men and 442 700 (437 200-447 900) in women, accounting for 47% of all incident cases in men and 28% in women. The greatest proportions of cancer deaths attributable to risk factors were for smoking (26%), HBV infection (12%), and low fruit/vegetable intake (7%) in men and HBV infection (7%), low fruit/vegetable intake (6%), and second-hand smoking (5%) in women. Conclusions Effective public health interventions to eliminate or reduce exposure from these risk factors, notably tobacco control and vaccinations against carcinogenic infections, can have considerable impact on reducing the cancer burden in China.

Abstract
BACKGROUND To evaluate the safety, tolerability, pharmacokinetics, and maximum tolerated dose (MTD) of copanlisib, a phosphatidylinositol 3-kinase inhibitor, in patients with advanced solid tumors or non-Hodgkin's lymphoma (NHL). PATIENTS AND METHODS Phase I dose-escalation study including patients with advanced solid tumors or NHL, and a cohort of patients with type 2 diabetes mellitus. Patients received three weekly intravenous infusions of copanlisib per 28-day cycle over the dose range 0.1-1.2 mg/kg. Plasma copanlisib levels were analyzed for pharmacokinetics. Biomarker analysis included PIK3CA, KRAS, BRAF, and PTEN mutational status and PTEN immunohistochemistry. Whole-body [(18)F]-fluorodeoxyglucose positron emission tomography ((18)FDG-PET) was carried out at baseline and following the first dose to assess early pharmacodynamic effects. Plasma glucose and insulin levels were evaluated serially. RESULTS Fifty-seven patients received treatment. The MTD was 0.8 mg/kg copanlisib. The most frequent treatment-related adverse events were nausea and transient hyperglycemia. Copanlisib exposure was dose-proportional with no accumulation; peak exposure positively correlated with transient hyperglycemia post-infusion. Sixteen of 20 patients treated at the MTD had reduced (18)FDG-PET uptake; 7 (33%) had a reduction >25%. One patient achieved a complete response (CR; endometrial carcinoma exhibiting both PIK3CA and PTEN mutations and complete PTEN loss) and two had a partial response (PR; both metastatic breast cancer). Among the nine NHL patients, all six with follicular lymphoma (FL) responded (one CR and five PRs) and one patient with diffuse large B-cell lymphoma had a PR by investigator assessment; two patients with FL who achieved CR (per post hoc independent radiologic review) were on treatment >3 years. CONCLUSION Copanlisib, dosed intermittently on days 1, 8, and 15 of a 28-day cycle, was well tolerated and the MTD was determined to be 0.8 mg/kg. Copanlisib exhibited dose-proportional pharmacokinetics and promising anti-tumor activity, particularly in patients with NHL.

Abstract
Flow cytometrically sex-sorted sperm have been widely used for improving reproductive management in the dairy industry. However, the industrial application of this technology in other domestic species is largely limited by the lower fertility after insemination. The aim of this study was to investigate effects of antioxidant supplementation during the sex-sorting and freezing process on the quality and functions of sorted sperm from Liaoning Cashmere goats. We tested the effects of antioxidant supplementation during sex-sorting and freezing process, including ascorbic acid-2-glucoside AA-2G, glutathione, melatonin and vitamin C (VC), on the quality and functions of sex-sorted fresh and frozen-thawed sperm. Based on these experiments, we performed deep insemination with sex-sorted sperm using our improved strategy, in comparison to unsorted sperm. In Experiment 1, compared with control group and other antioxidants, AA-2G supplementation significantly alleviated the degradation of motility and viability of fresh sperm after sorting and showed the highest percentage of sperm with normal morphology. In addition, AA-2G supplementation showed an evident protection against the sorting process-induced membrane and acrosome damage. In Experiment 2, AA-2G supplementation was most effective in protecting motility, while melatonin supplementation appears to facilitate the degradation of quality of frozen-thawed sex-sorted sperm. In Experiment 3, we performed deep insemination with sperm that were sorted and frozen in the presence of AA-2G and obtained a satisfying pregnancy rate comparable to that from unsorted sperm. The results showed that AA-2G supplementation efficiently protects quality and function of both fresh and frozen-thawed sex-sorted sperm of Cashmere goats, thus obtaining a satisfying pregnancy outcome.

Abstract
AKT1, also known as v-akt murine thymoma viral oncogene homolog 1, is involved in the regulation of cell-survival and anti-apoptotic activities, which may affect the pathogenesis of various cancers. However, the association between genetic variants of AKT1 and the risk of developing prostate cancer has not been investigated before. This study investigated the associations between three polymorphisms (rs1130214, rs3730358, and rs2494732) in AKT1 and the risk of development of prostate cancer in the Chinese Han population. Sequenom MassARRAY & iPLEX technology were used to genotype these polymorphisms in 493 Chinese Han patients with prostate cancer and 309 age-matched healthy individuals. Compared to the CC genotype of the rs3730358 polymorphism, the CT genotype of the same polymorphism was strongly associated with a decreased risk of prostate cancer (OR = 0.617, 95%CI = 0.390-0.976, P = 0.037). However, there was no significant difference between the allele frequency of the rs3730358 polymorphism and those of the other two polymorphisms (P > 0.05). Moreover, no significant difference was found in the haplotype analysis (P > 0.05). Our study found that the variant genotype CT of rs3730358 of AKT1 was associated with a decreased risk of prostate cancer, which suggested that this polymorphism could play an important role in the development of the disease.
