Hemoptysis is a serious and potentially life threatening event. Mortality is estimated at 13% for this chief complaint with age, volume of hemoptysis and receipt of blood products as risk factors for mortality. Hemoptysis is mostly seen in those with underlying congenital cardiac conditions or Cystic Fibrosis. We describe a unique case of a previously healthy 10 year old male who presented to the ED by EMS with a moderate volume episode of hemoptysis. He was admitted to the PICU where a sudden episode of massive hemoptysis precipitated by forced respiratory effort occurred during his examination. He decompensated and was emergently brought to the OR for airway evaluation by ENT and pulmonology. A large clot was found in the RML segment with brisk bleeding following removal of the clot. A 5 Fr bronchial blocker was placed to achieve hemostasis. Bronchial artery angiogram by IR demonstrated extravasation of contrast from right bronchial artery to segmental right lower lobe pulmonary artery shunt. He underwent embolization of the right bronchial artery. He was extubated the following day after no recurrent bleeding was confirmed with bronchoscopy. BA-PA fistulas are rare vascular anomalies in which an anastomosis is formed between systemic and pulmonary arteries. They are most commonly acquired, often described secondary to chronic inflammatory lung diseases. BA-PA fistulas can also be congenital and have been seldom described in the literature. Our case highlights the importance of this rare diagnosis, which must remain on a pediatric pulmonologist’s differential due to the significant associated mortality.

Background: Neonatal bronchopulmonary dysplasia (BPD) is a chronic neonatal respiratory disease that is caused by prolonged oxygenation and mechanical ventilation (MV), leading to respiratory distress (RD). Patients and methods: Prospective randomized controlled trial (RCT) with identification number TCTR20210622001 which was done at Tanta University Hospital (TUH) from August 2016 to February 2018 on 100 premature neonates who had RD and were put on MV. The examined neonates were classified into 2 groups: group 1, which received vitamin D supplementation, and group 2, which had placebo. Urinary β2-microglobulin (B2M) in addition to serum Krebs von den Lungen-6 (KL-6) levels were measured on the 1st and the14th day of hospitalization. Results: Significant decrease in urinary B2M and serum KL-6 levels in neonates of group 1 who were received vitamin D, if compared with group 2 neonates, who had taken placebo (P < 0.05). There was a significant decrease in the time of hospital stay in group 1 neonates, if compared with group 2 neonates (P < 0.05). Group 1 neonates showed a significant decrease of the developed BPD cases, if compared with group 2 (P < 0.05). Conclusion: Vitamin D supplementation may help in the prevention of BPD in neonates. Recommendation: Routine vitamin D supplementation to preterm neonates who are susceptible to develop BPD.

Non-anastomotic graft rupture in contemporary vascular prostheses is extremely rare and difficult to diagnose. We report a case of non-anastomotic vascular graft rupture diagnosed using non-obstructive aortic angioscopy. An 85-year-old male who underwent total arch replacement five years prior presented to our institution with chest pain. Based on contrast-enhanced angio-computed tomography and aortic angiography, we suspected extravasation of the thoracic vascular graft. Assessment of the vascular graft of the ascending aorta using aortic angioscopy revealed a red vascular graft defect. Non-anastomotic graft rupture was diagnosed by aortic angioscopy. The patient underwent 2-debranching thoracic endovascular aortic repair (Zone 0) with right subclavian artery-left common carotid artery-left subclavian artery bypass. Completion angiography and postoperative computed tomography showed the disappearance of the extravasation. Aortic angioscopy can help reach a definitive diagnosis in patients with graft rupture.

Background: Systemic lupus erythematosus (SLE) was characterized by extreme clinical heterogeneity and flare unpredictability. The immune homeostasis was the basis to maintain SLE stabilization. However, there were limited data to clarify the association between the SLE flare and immunophenotypes. Methods: Peripheral blood mononuclear cells were obtained from 93 SLE patients with low disease activity state (LDAS) and 66 healthy individuals. Circulating B and T subsets were defined using flow cytometric analysis as recommended by the Human Immunology Project Consortium. Based on the date of these subgroups cells, immunophenotypes of 93 LDAS patients were distinguished by principal components analysis (PCA) and cluster analysis. Results: Compared with healthy controls, the LDAS patients had higher proportions of plasma cells, double negative B cells, naïve B cells, CD8+T cells and regulatory T cells, and lower proportions of unswitched memory B cells and CD4+T cells. PCA indicated that the immunophenotypes had the abnormalities of the T and B cell axes among these LDAS patients. Cluster analysis showed that these patients could be divided into 3 groups: memory B cells group, naïve B cells group and T cells group. The patients in memory B cells group had the lower flare risk, SLEDAI scores, IgG levels and prednisone dose compared with the non-memory B cells group (including naïve B cells group and T cells group) patients. Conclusion: The peripheral immunophenotypes were associated with the SLE flare in the LDAS patients. The memory B cells dominant group patients had low risk of flare.

Constrictive pericarditis is an uncommon cause of right-sided heart failure. We present a case of idiopathic constrictive pericarditis presumably following a viral episode of acute pericarditis several months prior to the patient's presentation. This case highlights the necessity for a high clinical index of suspicion. Importantly, a series of imaging modalities were required to confirm the diagnosis and lead to a successful surgical intervention.

Aims The aim of this study is to investigate whether atropine when administered in persons without glaucoma during dobutamine stress echocardiography causes pupillary dilation. Methods and Results 144 patients referred for dobutamine stress echocardiography (DSE) study without any history of glaucoma were observed. 39 were excluded from the study because they did not receive atropine. Pupil diameter was measured at the same light conditions before and after each study session. 105 patients received during DSE atropine doses from 0.1 mg to 1.25mg (most patients received 0.25-0.75mg). For the total of 210 examined eyes pupil diameter remained statistically unaltered after each DSE test (3.65±0.799 mm before vs 3.63±0.766 mm after, p=0.737 respectively). Similarly, pupil diameter remained unchanged when left and right eyes were separately compared (Right Eye: 3.770 ± 0.812 before vs 3.752 ± 0.745 mm after, p=0.821 and Left eye: 3.521±0.770 before vs 3.499 ± 0.770 mm after, p=0.806, respectively). Diameter of right and left pupil remained unaltered also after grouping patients by gender and iris pigmentation. Age, weight, atropine dose and propranolol dose are not correlated with changes in pupil diameter. Conclusion Intravenous atropine, in usual doses administered in dobutamine stress echocardiography, does not cause mydriasis in adults without glaucoma. This is an indication that – though it is not currently recommended– atropine use during DSE in patients with narrow angle glaucoma may be potentially safe; further studies are needed to investigate this option.

Ecological theory suggests that the coexistence of species is promoted by the partitioning of available resources, as in dietary niche partitioning where predators partitioning prey. Yet, the mechanisms underlying dietary niche partitioning are not always clear. We used fecal DNA barcoding to investigate diets of seven nocturnal insectivorous bird and bat species. Low diet overlap (2-22%) supported resource partitioning among all species. Differences in diet corresponded with species identity, prey detection method, and foraging behavior of predators. Insects with ultrasonic hearing capabilities were consumed significantly more often by birds than by bats, consistent with an evolved avoidance of echolocating strategies. In turn, bats consumed a greater proportion of non-eared insects such as spruce budworm. Overall, our results suggest that evolutionary interactions among bats and moths translate to dietary niche partitioning and coexistence among bats and nocturnal birds.

The photoperiodic neuroendocrine system drives seasonal rhythms in reproduction. To get a better understanding of how annual cycling environmental cues impact reproductive function and plasticity in small, short-lived herbivores with different geographic origins, we investigated the mechanisms underlying integration of temperature in the photoperiodic-axis regulating female reproduction in tundra voles and in common voles. We show that photoperiod and temperature interact to determine appropriate physiological responses; there is species-dependent annual variation in the sensitivity to temperature for reproductive organ development. These findings are in line with our census data, showing an earlier onset of spring reproduction in cold springs, while reproductive offset in autumn is synchronized to photoperiod. The reproductive organs of tundra voles were relatively insensitive to temperature, whereas hypothalamic gene expression was generally upregulated at 10°C. Due to global warming, spring reproduction in common voles will be delayed, perhaps resulting in shorter breeding seasons and thus declining populations.

Objective: To investigate the prognostic factors of haploid hematopoietic stem cell transplantation in the treatment of X-linked lymphoproliferative syndrome. Methods: Seven children with X-linked lymphoproliferative syndrome diagnosed by XIAP gene analysis were enrolled into our hospital from June 2015 to September 2020. All the children were boys with a median age of 3.1 years (1.2-5.6 years) and a median duration of 9 months (5-28 months) from the disease onset to accepting HSCT. Disease status was assessed before transplantation, with partial remission in 6 cases and disease progression in 1 case. Five children received paternal hematopoietic grafts while two cases experienced secondary transplantations from maternal grafts. Preconditioning regimens consisted of Etoposide (VP-16), Fludarabine (Flu), Busulfan (BU), Anti-thymocyte globulin, but the Busulfan was replaced by Melphalan in the two cases who received secondary transplants. The median count of infused mononuclear cells (MNC) was 9.07×108/kg [(8.45-9.98)×108/kg] and CD34-positive cells was 6.45×106/kg [(4.67-8.53)×106/kg].

We investigate the equiform-Bishop Hasimoto surfaces ℘(\sigma, t) in Minkowski 3-space in this paper. In E^3_1, in different three cases, the geometric properties of equiform-Bishop Hasimoto surfaces are discussed. For each case, the equiformBishop Gaussian and mean curvatures of the equiform-Bishop Hasimoto surface are determined. Then, in E^3_1, we characterize the parameter equiform Bishop curves of equiform-Bishop Hasimoto surfaces.

In this paper, an Extended Non-Linear State Observer (ENSO) is proposed for the estimation of accurate State of Charge (SOC) of lithium-ion battery. The Two-RC equivalent circuit model is utilized to describe the dynamic behaviour of the lithium-ion battery, based on the circuit state equations the proposed ENSO is designed for the estimation of SOC. The ninth-order polynomial fitting curve is assumed to be a representation of a highly non-linear relationship between Open Circuit Voltage (OCV) and the SOC. Moreover, the stability and convergence rate of the proposed ENSO is guaranteed by Lyapunov’s stability analysis. The performance of the proposed observer is compared with well-extinguished methods i.e., Unscented Kalman Filter (UKF) and Sliding Mode Observer (SMO) algorithms. The proposed method has given better dynamic performance with accurate SOC, reducing computational cost and enhance the convergence capability as compared to conventional methods. The Proposed model effectiveness has been validated through the MATLAB/Simulink platform.

In a world where pandemics are a matter of time and increasing urbanization of the world's population, governments should be prepared with pandemic intervention policies to minimize the crisis direct and indirect adverse effects while keeping normal life as much as possible. Successful pandemic intervention policies have to take into consideration the unique behavior of individuals in different types of buildings and social contexts. In this study, we propose a Spatio-temporal model and in silico simulation to evaluate pandemic intervention policies in four types of buildings - home, office, school, and mall. We show that indeed each building type has a unique pandemic spread and therefore a different optimal intervention policy.

If we look closely at nature, we can see that, although it appears to be very plain and systematic on the surface, it conceals many complexities underneath it. Since technology follows the same ‘simple-yet-complex’ theory as nature, researchers have often attempted to apply what they have learned from nature to complex technological Algorithms that are used to solve a few real-world human problems. There has been a rapid rise in research in this area over the last decade. Nature-inspired algorithms are now used in almost every field of science. While it has been extended to a variety of fields, the scope of this paper is limited to its use in the optimization and computer Intelligence. The main goal of optimization and Computer intelligence applications is to obtain, handle, and use the massive amount of data stored in distributed databases, which can be structured, semi-structured, or unstructured. This is a developing field that is moving toward more intelligent and human-centric applications. This paper provides an overview of important nature-inspired techniques for optimising various aspects of Semantic Web applications, including knowledge bases, content filtering, information retrieval, and inference mechanisms.

Objective: To describe the pattern and population characteristics of pediatric and adolescent gynecological (PAG) problems in China. Design: A clinic-based retrospective study of gynecological patients (aged 0-18 years) over a period of 13 years, and a systematic review of related studies in China. Setting: Department of PAG at The Children’s Hospital of Zhejiang University School of Medicine. Population or Sample: The final analyses included 97,252 patients with gynecological problems. Methods: Descriptive analysis was conducted to evaluate the pattern of PAG problems. The weighted average of PAG problem percentages were calculated. Main Outcome Measures: Spectrum of PAG problems Results: The number of first-visit PAG patients increased from 4,582 to 11,876 from 2006 to 2018. Overall, genital inflammation was the most common presentation (57·0%), followed by early puberty (18·2%). The disease pattern varied across age groups, the most common problems were genital inflammation for age 0-6 years; genital inflammation and early puberty for age 7-9 years; consultation of growth and development, genital inflammation and menstrual disorder for age 10-18 years. Summarizing twenty previous studies of outpatient PAG patterns in China, we found an average weighted percentage of 48·8% for genital inflammation and 25·2% for menstrual disorder. Conclusion: Genital inflammation, early puberty, consultation of growth and development and menstrual disorder were common issue for pediatric and adolescent patients with gynecological problems in China.

This scoping review identifies characteristics of prenatal counseling for extreme prematurity at the limit of viability. Embase, Medline, Web of Science, Cochrane, CINAHL, and Google Scholar were searched. 47 articles were included. Almost half of them were published between 2018 and 2021. The following characteristics could be identified: personalization, parent-physician relationships, shared decision-making, bias, emotions and anxiety, psychosocial factors, parental values, religion, spirituality and hope, quality of life, and uncertainty. A trend in time towards personalization was also remarkable. However, more research is needed on parental perspectives on personalizing prenatal counseling.

Aim of the study This study was planned to determine the second generation drug resistance and molecular epidemiological profile of multidrug resistant Mycobacterium tuberculosis strains isolated from different geographical regions of Turkey. Methods In our study, 63 MDR M. tuberculosis isolates were evaluated for the drug susceptibility sent from different tuberculosis laboratories of Turkey. Secondary antituberculosis drugs resistance was evaluated by indirect proportion method. Epidemiological origins were evaluated by using IS6110-RFLP and spoligotyping methods. Results Cycloserine, ethionamide, capreomycin, thiacetozone, ofloxacin, kanamsin and paraaminosalicylic acid resistance rates were 15.87%, 19.04%, 7.93%, 6.34%, 11.11%, 12.69% and 6.34.%, respectively. According to spoligotyping results, 11 different patterns were obtained, including 52 isolates consisting of 5 clusters and 11 patterns consisting of a single isolate. When we compared our results with the spoligotype database in the world; 42 of 52 isolates forming 5 clusters were identified as predefined spoligotypes (LAM7-TUR, LAM9, T clade). 10 isolates showed the characteristics of the U spoligotype family. Of the 11 isolates that produced 11 different patterns, 8 were Haarlem and T spoligotypes. It was found that 2 isolates had the characteristics of Orphan and 1 isolate had the characteristics of BOV family. Conclusison In our study, spoligotype families that are common in our country and in the world were determined.

Introduction: Diagnostic tests for growth hormone (GH) deficiency, have low specificity, so, it could suppose different results in treatment, because of false positives. Objectives: To evaluate the growth of children with isolated GH deficiency treated with GH in comparison with children with idiopathic short stature treated or not treated. Methods: Ambispective descriptive study of patients under 14 years old treated in our department in the last 14 years for isolated GH deficiency (Group A), in comparison with those diagnosed with idiopathic short stature treated (Group B) and not treated with GH (Group C). Results: 67 male patients were studied in Group A, who showed a gain of total height of 1.24 SD, which was 0.27SD lower than target height. Group B had 30 boys, who showed a gain of height of 1.47SD. There was an improve in final height according to target height of 0.29 SD. 42 boys were studied in Group C. These boys showed an improvement of 0.37 SD from initial height, although they did not reach target height (difference of 0.59 SD). Finally, both treated groups (A and B) showed average final heights (-1.52SD and -1.31SD), while Group C showed shorter final height (-2.03SD). Conclusions: Final height of isolated GH deficiency is similar to those patients with idiopathic short stature treated, without any statistical difference, while both treated groups, were taller than idiopathic short stature non treated.

Purpose: To investigate perioperative clinicopathological predictors and establish a predictive nomogram for survival in patients with renal cell carcinoma (RCC) and venous tumor thrombus (VTT) undergoing nephrectomy and thrombectomy. Methods: Patients with RCC and VTT undergoing nephrectomy and thrombectomy were included in the study between January 2014 and June 2020. Cox regression analysis was used for univariate and multivariate survival analyses. A predictive nomogram for survival was established and internally validated using bootstrap resampling method. Results: A total of 223 patients were included in this study. The median age was 60 years (IQR, 53–66 years), consisting of 171(76.7%) males and 52(23.3%) females. The median follow-up time was 17.0 months (range, 1-74 months), 26.5% (59 of 223) patients died of all causes. In multivariable analysis, hemoglobin less than the low limit of normal (HR, 1.73; 95% CI, 1.01–2.95; P =0.045), sarcomatoid feature (HR, 3.67; 95% CI, 1.98–6.83; P<0.001), perirenal fat invasion (HR, 1.79; 95% CI, 1.04–3.08; P=0.034), histological subtype (HR, 2.74; 95% CI, 1.39–5.42; P=0.004), and metastasis at surgery (HR, 1.71; 95% CI, 1.01–2.91; P =0.047) were independent predictors of overall survival. The result of internal validation presented that the predictive performance of the nomogram for survival measured by C-index was 0.77. Conclusions: We developed a predictive nomogram with well internal validation for survival in patients with RCC and VTT, which can greatly promote risk stratification and treatment planning, as well as more accurate selection criteria for clinical trials of adjuvant therapies. External validation is still required to assess its universal applicability.

Background Migraine — an episodic headache —is one of the most common types of primary Headache. Migraine is considered a serious health problem that affects the quality of life. During university life, students often report increased levels of stress, depression, anxiety, and irregular sleep, all of which are associated with migraines.Our aim was to determine the prevalence of migraine headaches among medical campus students at university of Khartoum, Sudan. Based on available data, migraine is on the rise in both general populations as well as university students. Methods In this cross-sectional and descriptive study, study population was composed of students registered to faculty of medicine, Dentistry and pharmacy at Khartoum University in the academic years of 2020-2021. Out of these 318 of them accepted to participate. Participants who had two or more headaches in the last 3 months formed the headache group. Afterwards, two preliminary questions were applied to the headache group and participants with at least one affirmative response were asked to perform the validated ID-Migraine™ test. Results The mean age of 318 students participated in the study was 19.23 ± 1.84 (17-39 years), with adolescents: adult ratio being 2.5:1. 1613 students (43.7%) did have at least two headaches in the last three months. Migraine-type headache was detected in 266 subjects (7.2%) based on the ID-Migraine™ test. Of the migraine group, 72 were male (27.1%) and 194 were female (72.9%). There was no significant difference in migraine prevalence between adolescent and adult age groups. Conclusions With prevalence similar to adults, primary care physicians should be aware of the probability of migraine headaches in university students in order to maintain a successful school performance.

Background: Paediatric primary hypertension is partly attributable to the childhood obesity epidemic. 24-hour ambulatory blood pressure monitoring could better identify blood pressure alterations in this group. The aim of the present study is to estimate the proportion of blood pressure abnormalities in obese children and the prevalence of the different blood pressure categories according to the American Heart Association. Procedure: A case-control study was designed (n=154, 53.2%boys) including 77 obese and 77 normal-weight children aged 7-15 years. International Obesity Task Force reference values were used to define obesity and normal weight. Office blood pressure and ambulatory blood pressure for 24h were assessed and children were classified according to the American Heart Association categories. Results: Means of systolic and diastolic blood pressure were higher in obese participants. Office’s systolic hypertension was present in 19.5% of obese vs 5.2% of normal-weight and night-time systolic hypertension affected 11.7% of obese vs 2.6% of normal-weight (p <0.05). Non-dipping was present in 54.5% of obese vs 35.1% of normal-weight in the systolic register (p=0.015). Prevalence of abnormal blood pressure loads was higher in obese. Exclusively in the night-time, ambulatory hypertension was diagnosed in obese children (3.9%). A high proportion of obese were uncategorized. Conclusions: A high proportion of blood pressure abnormalities has been observed taking into consideration the entire 24h, daytime and night-time periods. Only with the office BP reading, the primary hypertension seems to be over-diagnosed. There is still an urgent need for more comprehensive studies linking ambulatory blood pressure patterns to cardiovascular event

Aim: Cardiovascular patients have a high risk for Drug-related problems(DRPs) , howevre studies the prevalence and risk factor for these patients in china are still unkown.This study was conducted to identify characteristics and risk factors associated with DRPs of cardiovascular patients in China, and assess the effectiveness of pharmaceutical practice. Methods:This was a retrospective study in a cardiology department of an academic teaching hospital for 12 months. A total of 1729 patients were enrolled. Pharmaceutical care was implemented by a pharmacy team. Drug-related problems were categorized by the Pharmaceutical Care Network Europe(PCNE) classification V9.1. Main outcome measure were the prevalence, characteristics and risk factors of drug-related problems. Results: During this study, 203 DRPs were found in 152(8.8%) patients,204 intervention, the success rate of intervention was 99.0%. Hospitalized days ≥ 8.5(OR=1.925,95% CI:1.363-2.717) had a better sensitivity and specificity in predicting the occurrence of drug-related problems, compared with patient age and number of concomitant diseases. The most common type of drug-related problems was “Effect of drug treatment not optimal”( 34.5%) , “patient transfer related” was the primary cause of drug-related problems (35.3%). Among the top medications associated with drug-related problems were Auxiliary medications (20.2%) followed by antianginal medications (17.2%) , Antiplatelet agents (11.8%), and β-Adrenergic receptor antagonists (11.8%). Conclusion: Drug-related problems are relatively common in hospitalized cardiovascular patients in China, “patient transfer related” is the primary cause and “Hospitalized days” is the major risk factors for these patients. Pharmacist intervention can identify and resolve pertinent drug-related problems to optimize medication therapy.

Critical transitions, sudden responses to slow changes in environmental drivers, are inherent in many dynamic processes, prompting a search for early warning signals. We apply this framework to understanding the coffee rust disease, which experienced an unprecedented outbreak in Mesoamerica in 2012-2013, likely a critical transition. Based on monthly infection data from 128 study quadrats in a 45-ha plot in southern Mexico from 2014 to 2020, we find that the persistent seasonal epidemic following the initial outbreak collapses in an evident subsequent critical transition. Characteristic signals of “critical slowing down” precede this collapse and are correlated with reduced rainfall, as expected from climate change, and planting of rust-resistant varieties, an ongoing management intervention. Recoveries from catastrophes may themselves be experienced as a critical transition and managers should consider the larger dynamical landscape for the possibility of subsequent transitions. Early warning signals could therefore be useful when evaluating mitigation effectiveness.

Currently, the control strategies of Botrytis cinerea mainly include chemical and biological methods, leading to environmental pollution and other problems. Ecological control involves suppressing the disease by regulating the facility environment. However, the infection process and the response mechanism of plants under different temperatures and humidity remain unclear. This study measured four cell wall–degrading enzymes, used light microscopy, scanning electron microscopy, and transmission electron microscopy to explore the impacts of temperature and humidity on the physiological and structural changes of the infection process and host response, and studied their interaction by correlation analysis. We observed that B. cinerea could cause infection due to undifferentiated hyphae under low humidity. The most severe infection was under the medium temperature and high humidity (MH) treatment, wherein the hyphae released cell wall–degrading enzymes to penetrate the host cells. Under high temperature, the mycelia grew without pathogenicity, while under low temperature, the gley time of the infection increased due to low-temperature stress. Additionally, we found that the structure of the infected host cells under different temperatures and humidity changed differently, including cell wall thickening, plasma membrane degradation, chloroplast disorganization, and starch granule anomalies. We also found that different temperatures and humidity had specific effects

The Tephritidae is one of the largest families of Diptera with high diversity and globally wide distribution, including a range of important agricultural pests. However, the origin, phylogeny and evolution history of Tephritidae remain poorly understood. We undertook the first comprehensive mitogenomic study covering phylogenetic reconstruction, divergence time estimation and historical biogeography analyses by analyzing 147 mitochondrial genomes representing three subfamilies, seven tribes, 11 genera and 82 species. The results recovered all the three subfamilies, seven tribes and 11 genera as monophyletic group. Within Dacini subfamily, our phylogeny strongly supported the sister group relationship of (Zeugodacus + Dacus) + Bactrocera, which further supported to raise Zeugodacus as generic level of Dacini. On the other hand, our molecular phylogenetic analyses did not align well with the currently recognized subgeneric designations within Ceratitis, Dacus and Zeugodacus. Some subgenera were recovered as polyphyletic or paraphyletic, implying the incongruence between morphological characters and mitogenomic data. Neither the taxa within the Ceratitis FARQ complex nor those within the Bactrocera dorsalis complex could be clearly distinguished as distinct species corresponding to the morphospecies by mitochondrial phylogenetic tree. Divergence time estimation and historical biogeography analyses indicated that the earliest common ancestor of the Tephritidae, originated in the Palearctic realm at 138.92-71.44 Ma, with the subsequent divergence into Dacinae + Trypetinae and Tephritinae at 115.19-67.45 Ma equally in the Palearctic realm. Dacini might have originated in Laurasia rather than Gondwana and diverged into Bactrocera and Dacus + Zeugodacus at 48.43-28.70 Ma after India plate docked with Laurasia.
