Abstract
Metabolism in most organisms can show variations between the day and night. These variations may also affect the composition of products derived from livestock. The aim of the present study was to investigate the difference in composition between the day milk and night milk of dairy cows. Ten multiparous Holstein cows (milk yield = 25.2 ± 5.00 kg/d) were randomly selected during mid lactation. Milk samples were collected at 0500 h ("night milk") and 1500 h ("day milk") and analyzed to determine their composition. Mid-infrared spectroscopy was used to analyze macronutrient content of milk. Metabolomics and lipidomics were used to detect and analyze small molecules and fatty acids, respectively. An automatic biochemical analyzer and ELISA kits were used to determine biochemical indicators, as well as antioxidant and immune parameters in the milk. Though milk fat, protein, lactose, and total milk solids were not different between day milk and night milk, small molecules, metabolites and lipids, and hormones and cytokines differed between day milk and night milk. Regarding biochemical and immune-related indicators, the concentrations of malondialdehyde, HSP70, and HSP90 in night milk were lower than that in day milk. However, interferon-γ levels were higher in night milk. Additionally, night milk was naturally rich in melatonin. Lipidomics analyses showed that the levels of some lipids in night milk were higher than those in day milk. Metabolomics analyses identified 36 different metabolites between day milk and night milk. Higher concentrations of N-acetyl-d-glucosamine, cis-aconitate, and d-sorbitol were observed in day milk. However, the other 33 metabolites analyzed, including carbohydrates, lipids, AA, and aromatic compounds, showed lower concentrations in day milk than in night milk. The present findings show that the composition of night milk differs considerably from that of day milk. Notable changes in the circadian rhythm also altered milk composition. These results provide evidence to support the strategic use and classification of day milk and night milk.

Abstract
PURPOSE The liver segments divided by Couinaud classification method are used to understand the functional anatomy of liver, which is significant in hepatic resection surgery. In Couinaud classification method, each third-order branch of the portal vein (PV) defines the supplied territory of a corresponding liver segment. However, the accuracies of the reconstruction and classification of PV are affected by the complicated structure of the vein. The purpose of this paper is to develop a separation and classification method that can accurately extract the liver segments. METHODS In this paper, a multiple feature-based method is proposed to obtain liver segments. Because the portal and hepatic veins usually connect in the vessel segmentation result, the PV is first completely separated based on the different strategies for minimal node cut using fused features of topology and appearance. Meanwhile, all bifurcation nodes of PV are detected. The bifurcation nodes are initial ordered through their linkages to classify the branches. Then, the feature of the vascular topology is used to refine the orders of bifurcation nodes. The bifurcation nodes with the refined orders classify the branches between them, and the third-order branches of PV are obtained. The liver segments are eventually obtained through the third-order branches. RESULTS The separation and classification in the proposed method are evaluated on the CT and MR datasets. The average values of Dice, Jaccard, Recall, and Precision obtained by the proposed method are 93.00%, 87.90%, 93.47%, and 93.19%, respectively. Compared with the state-of-the-art methods, the separation results obtained by the proposed method are more accurate. The branches of PV are classified based on the separation result. According to the third-order branches, eight liver segments correspond to the different functional areas are precisely extracted. CONCLUSIONS The proposed method achieves a high accuracy for the liver segment extraction. And the extracted liver segments are significant for the preplanning of resection surgery.

Abstract
Liver is an incompressible organ that maintains its volume during the respiration-induced deformation. Quantifying this deformation with the incompressible constraint is significant for liver tracking. The constraint can be accomplished with retaining the divergence-free field obtained by the deformation decomposition. However, the decomposition process is time-consuming, and the removal of non-divergence-free field weakens the deformation. In this study, a divergence-free fitting-based registration method is proposed to quantify the incompressible deformation rapidly and accurately. First, the deformation to be estimated is mapped to the velocity in a diffeomorphic space. Then, this velocity is decomposed by a fast Fourier-based Hodge-Helmholtz decomposition to obtain the divergence-free, curl-free, and harmonic fields. The curl-free field is replaced and fitted by the obtained harmonic field with a translation field to generate a new divergence-free velocity. By optimizing this velocity, the final incompressible deformation is obtained. Moreover, a deep learning framework (DLF) is constructed to accelerate the incompressible deformation quantification. An incompressible respiratory motion model is built for the DLF by using the proposed registration method and is then used to augment the training data. An encoder-decoder network is introduced to learn appearance-velocity correlation at patch scale. In the experiment, we compare the proposed registration with three state-of-the-art methods. The results show that the proposed method can accurately achieve the incompressible registration of liver with a mean liver overlap ratio of 95.33%. Moreover, the time consumed by DLF is nearly 15 times shorter than that by other methods.

Abstract
Pollution in soil by petroleum hydrocarbon has become a global environmental problem. The bioremediation of petroleum hydrocarbon-contaminated soil was enhanced with the combination of an isolated indigenous bacterial consortium and biosurfactant. The biodegradation efficiency of total petroleum hydrocarbon (TPH) was increased from 12.2% in the contaminated soil to 44.5% and 57.7% in isolated consortium and isolated consortium & 1.5 g sophorolipid (SL)/kg dry soil, respectively. The half-life of TPH degradation process was decreased from 32.5 d in the isolated consortium reactor to 20.4 d in the isolated consortium & 1.5 g SL/kg dry soil. The addition of biosurfactant into contaminated soils improved the TPH desorption from solid matrix to the aqueous solution and the subsequent solubilization, which ultimately improved the bioavailability of TPH in contaminated soils. Biosurfactant also served as carbon sources which contributed to the stimulation of cell growth and microbial activity and accelerated the biodegradation process via co-metabolism. The enzyme activities and quantities of functional genes were demonstrated to be incremented in SL reactors. The biosurfactant improved the TPH bioavailability, stimulated the microbial activities and participated in the co-metabolism. The combination of bioaugmentation and SL benefitted the bioremediation of petroleum hydrocarbon-contaminated soil.

Abstract
A Gram-stain-negative, strictly aerobic, motile by gliding, rod-shaped and non-flagellated marine bacterium strain, designated BOM4T, was isolated from a mussel inhabiting the Tangyin hydrothermal field of the Okinawa Trough. The growth temperature was in the range of 16–40 °C, and the optimum temperature was 37 °C. Optimal growth occurred at pH 7.0 and in the presence of 1 % (w/v) NaCl. The predominant isoprenoid quinone of strain BOM4T was identified as menaquinone-6 (MK-6). The predominant fatty acids (>10 %) were iso-C15 : 0(43.8 %) and iso-C17 : 0 3-OH (17.5 %). The major polar lipids comprised one phosphatidylethanolamine, three unidentified aminolipids and two unidentified lipids. Based on 16S rRNA gene sequence analyses, strain BOM4T was found to be most closely related to
Gramella aestuarii
JCM 17790T (96.7 %), followed by
Gramella flava
JLT2011T (96.1 %),
Gramella sediminilitoris
GHTF-27T (95.6 %) and
Gramella gaetbulicola
RA5-111T (95.5 %) and with lower sequence similarities (93.7- 95.4 %) to other species of the genus
Gramella
. Genome relatedness between strain BOM4T and
G. aestuarii
JCM 17790T was computed using both average nucleotide identity and DNA–DNA hybridization with values of 75.6 and 19.3±2.4 %, respectively. The DNA G+C content of strain BOM4T was 41.4 mol%. On the basis of polyphasic analysis, strain BOM4T was considered to represent a novel species of the genus
Gramella
, for which the name Gramella bathymodioli sp. nov. is proposed. The type strain is BOM4T (=MCCC 1K03735T=JCM 33424T).

Abstract
Graph-based groupwise registration methods are widely used in atlas construction. Given a group of images, a graph is built whose nodes represent the images, and whose edges represent a geodesic path between two nodes. The distribution of images on an image manifold is explored through edge traversal in a graph. The final atlas is a mean image at the population center of the distribution on the manifold. The procedure of warping all images to the mean image turns to dynamic graph shrinkage in which nodes become closer to each other. Most conventional groupwise registration frameworks construct and shrink a graph without considering the local distribution of images on the dataset manifold and the local structure variations between image pairs. Neglecting the local information fundamentally decrease the accuracy and efficiency when population atlases are built for organs with large inter-subject anatomical variabilities. To overcome the problem, this paper proposes a global-local graph shrinkage approach that can generate accurate atlas. A connected graph is constructed automatically based on global similarities across the images to explore the global distribution. A local image distribution obtained by image clustering is used to simplify the edges of the constructed graph. Subsequently, local image similarities refine the deformation estimated through global image similarity for each image warping along the graph edges. Through the image warping, the overall simplified graph shrinks gradually to yield the atlas with respecting both global and local features. The proposed method is evaluated on 61 synthetic and 20 clinical liver datasets, and the results are compared with those of six state-of-the-art groupwise registration methods. The experimental results show that the proposed method outperforms non-global-local method approaches in terms of accuracy.

Abstract
Background:B cell differentiation and dysfunction play a key role in the pathogenesis of Systemic lupus erythematosus (SLE). Bone marrow (BM) is the development organ of B cells, and also the home and residence place of plasma cells and memory B cells. However, there is a lack of studies on B cells in BM with lupus.Objectives:To map the development of BM and peripheral B cells and investigate the mechanism of abnormal early B cell development in SLE.Methods:A total of 11 SLE patients and 5 age- and sex-matched controls were recruited.BM and peripheral B cell subsets were measured by flow cytometry. sorting-purified B cell subsets were subject toSingle-cell RNA sequencing (scRNA-seq) and functional studies. Plasma cytokines and secreted immunoglobulins were detected by Luminex or ELISA. Disease activity of SLE patients was measured using the SLE Disease Activity Index (SLEDAI).Results:In the present study, we find out that the percentage of monocytes in MNC (p=0.070) and plasma cells(p=0.001)in CD19+ were significantly decreased in BM of SLE, compared to healthy controls. While, SLE patients had increased T%MNC(p=0.008) and B%CD19+(p=0.002) in BM that controls. In detail, the B cell subsets of bone marrow in patients with active lupus (SLEDAI≥8 score) were seriously disordered, showing the increasing T%MNC(p=0.049), propre-B%CD19+ (p=0.006)and immature B cell%CD19+ (p=0.010) than healthy donors. propre-B%CD19+ exhibited good relationship with SLEDAI. By integrating single B cell expression profiling and repertoire analysis, we map the development of B cells in BM and peripheral and pathogenic characteristics of early B cells, especially propre-B.Conclusion:These findings demonstrated that early B cells in BM, especially propre-B are abnormally differentiated with dysregulations. BM is an important organ targeted by SLE. This studyis not only to clarify the internal mechanism of the disorder of differentiation of B cells, but also to provide new clues for the targeted diagnosis and treatment of SLE.References:[1]Palanichamy, A., et al.,Neutrophil-mediated IFN activation in the bone marrow alters B cell development in human and murine systemic lupus erythematosus.J Immunol, 2014.192(3): p. 906-18.[2]Papadaki, H.A., J.C.

Abstract
A Gram-stain-negative, strictly aerobic, oval-shaped, non-motile bacterium with no flagella, designated strain SCR17T, was isolated from a shrimp gill habitat in Tangyin hydrothermal field of Okinawa Trough. Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain SCR17T formed a lineage within the family 'Rhodobacteraceae', and shared 16S rRNA gene sequence similarity of 93.2-96.2 % to the related genera Aquicoccus and Roseivivax. Strain SCR17T was able to grow with 0-14 % (w/v) NaCl (optimum, 9-10 %). The sole respiratory quinone was ubiquinone-10. The major polar lipids of strain SCR17T comprised phosphatidylcholine (PC), phosphatidylglycerol (PG), phosphatidylethanolamine (PE), an unidentified aminolipid (AL), an unidentified phospholipid (PL) and an unidentified lipid (L). The predominant fatty acids (more than 10 % of the total fatty acids) were C18 : 1ω7c or/and C18 : 1ω6c, anteiso-C15 : 0, C16 : 0 and C19 : 0 cyclo ω8c . The genomic DNA G+C content of strain SCR17T was 67.7 mol%. Based on polyphasic taxonomic analyses, strain SCR17T is considered to represent a novel species in a new genus of the family 'Rhodobacteraceae', for which the name Carideicomes alvinocaridis gen. nov., sp. nov. is proposed. The type strain of Carideicomes alvinocaridis is SCR17T (=JCM 33426T=MCCC 1K03732T). The discovery of a novel host-associated bacterium in hydrothermal fields provides an opportunity for the study of host-bacterial symbiosis in extreme environments.

Abstract
Blue holes are unique geomorphological units characterized by steep redox and biogeochemical gradients. Yongle Blue Hole is located on the largest atoll (Yongle Atoll) of the western Xisha Islands in the South China Sea. A Gram-stain-negative, facultatively anaerobic, non-motile, non-flagellated marine bacterium with creamy white colonies, designated JC036T, was isolated from Yongle Blue Hole. Cells were short-rod-shaped and catalase-negative. 16S rRNA gene sequence analysis showed that sequence similarities were lower than 91.6 % against all validly named species in the familyProlixibacteraceae; a reconstructed phylogenetic tree indicated that strain JC036Tformed a lineage with strains in the familyProlixibacteraceae. Growth occurred at 4–37 °C (optimum, 28 °C), at pH 5.0–9.0 (optimum, 7.0) and in the presence of 2–6 % (w/v) NaCl (optimum, 3 %). The prevalent isoprenoid quinone of strain JC036Twas menaquinone-7 (MK-7). Iso-C15 : 0and iso-C17 : 03-OH were the predominant fatty acids. The major polar lipids included a phospholipid, phosphatidylethanolamine, an aminophospholipid and four unidentified lipids. The genomic DNA G+C content of strain JC036Twas 37.8 mol%. Based on physiological and biochemical characteristics and whole genome comparisons, we propose a new genus and species,Puteibacter caeruleilacunaegen. nov., sp. nov., within the familyProlixibacteraceae. The type strain ofPuteibacter caeruleilacunaeis JC036T(=JCM 33128T=MCCC 1K03579T). From this study, a deeper understanding of the community of the microorganism and their roles in biogeochemical cycles, especially anaerobic bacteria, is provided.

Abstract
AIM Both type 1 and type 2 diabetes are associated with greater risk of a variety of cancers. However, the association between gestational diabetes mellitus (GDM) and risk of cancer has so far not been well addressed. This study aimed to summarize the epidemiological evidence of the association between GDM and subsequent risk of cancer. METHODS PubMed and Embase databases were searched for relevant studies, and a random-effects model was used to calculate the summary relative risks (RRs) along with the corresponding 95% confidence intervals (CIs). RESULTS A total of 17 observational studies were selected, comprising 7 case-control and 10 cohort studies. Pooled effect estimates retrieved from these 17 studies showed that GDM was associated with an increased risk of breast cancer in Asia (pooled RR: 1.31, 95% CI: 1.01-1.70), but not in other regions, and also with thyroid cancer (RR: 1.28, 95% CI: 1.16-1.42), stomach cancer (RR: 1.43, 95% CI: 1.02-2.00) and liver cancer (RR: 1.27, 95% CI: 1.03-1.55). However, GDM was not associated with any increased risk of colon (RR: 1.41, 95% CI: 0.90-2.21), colorectal (RR: 1.16, 95% CI: 0.95-1.41), ovarian (RR: 1.14, 95% CI: 0.90-1.44), cervical (RR: 1.02, 95% CI: 0.81-1.29), pancreatic (RR: 3.49, 95% CI: 0.80-15.23), brain and nervous system (RR: 1.26, 95% CI: 0.80-1.97), blood (leukaemia, RR: 0.77, 95% CI: 0.45-1.30), endometrial (RR: 0.77, 95% CI: 0.20-2.98), skin (RR: 1.13, 95% CI: 0.81-1.59) or urological (RR: 0.98, 95% CI: 0.73-1.31) cancers. CONCLUSION GDM is associated with a greater risk of cancer in women, including breast, thyroid, stomach and liver cancers. However, further investigation is nonetheless warranted.

Abstract
Background Patients with diffuse large B-cell lymphoma treated with first-line anthracycline-based immunochemotherapy and remaining in remission at 2 years have excellent outcomes. This study assessed overall survival (OS) stratified by progression-free survival (PFS) at 24 months (PFS24) using individual patient data from patients with DLBCL enrolled in multi-center, international randomized clinical trials as part of the Surrogate Endpoint for Aggressive Lymphoma (SEAL) Collaboration. Patients and methods PFS24 was defined as being alive and PFS24 after study entry. OS from PFS24 was defined as time from identified PFS24 status until death due to any cause. OS was compared with each patient's age-, sex-, and country-matched general population using expected survival and standardized mortality ratios (SMRs). Results A total of 5853 patients enrolled in trials in the SEAL database received rituximab as part of induction therapy and were included in this analysis. The median age was 62 years (range 18-92), and 56% were greater than 60 years of age. At a median follow-up of 4.4 years, 1337 patients (23%) had disease progression, 1489 (25%) had died, and 5101 had sufficient follow-up to evaluate PFS24. A total of 1423 assessable patients failed to achieve PFS24 with a median OS of 7.2 months (95% CI 6.8-8.1) after progression; 5-year OS after progression was 19% and SMR was 32.1 (95% CI 30.0-34.4). A total of 3678 patients achieved PFS24; SMR after achieving PFS24 was 1.22 (95% CI 1.09-1.37). The observed OS versus expected OS at 3, 5, and 7 years after achieving PFS24 was 93.1% versus 94.4%, 87.6% versus 89.5%, and 80.0% versus 83.7%, respectively. Conclusion Patients treated with rituximab containing anthracycline-based immunochemotherapy on clinical trials who are alive without progression at 24 months from the onset of initial therapy have excellent outcomes with survival that is marginally lower but clinically indistinguishable from the age-, sex-, and country-matched background population for 7 years after achieving PFS24.

Abstract
Objective:To analyze the relationship between ABO blood groups and otoacoustic emissions in full-term newborns, including the occurrence of SOAE and the amplitudes of DPOAE. Method:A total of eighty normal hearing female neonates were included in the study, with equal number of participants in each of the ABO blood group. Measurements of SOAE and DPOAE were collected from both ears of all participants. Result:The blood group O subjects showed significantly fewer SOAE occurrences and lower DPOAE amplitudes at 793 Hz, 1 257 Hz and 1 587 Hz than subjects with other three blood groups both in the left and right ears. Conclusion:The full-term neonates with blood group O have lower SOAE occurrence than other three blood group individual. The blood group O individuals have the lowest amplitude at 793 Hz, 1 257 Hz and 1 587 Hz of both ears.

Abstract
Objective: To investigate the expression of IL-18 in peripheral blood of HBsAg positive parturients in intrauterine transmission of HBV. Methods: A case-control study was conducted in 282 HBsAg positive parturients and 43 health parturients (control group) in Northwest Women and Children Hospital of Shaanxi Province. Enzyme-linked immunosorbent assay (ELISA) was used to detect five serological makers of hepatitis B, real time PCR was used to detect HBV DNA, and flow liquid chip method was used to detect IL-18 levels in peripheral blood of parturients and newborns. Results: The incidence of dominant HBV infection (DBI), occult HBV infection (OBI) and intrauterine transmission of HBV were 8.42% (24/285), 40.00% (114/285) and 48.42% (138/285), respectively. The level of IL-18 in peripheral blood of HBsAg-negative parturients were significantly lower than those of HBsAg-positive parturients (P=0.001), non-HBV intrauterine transmission (NBIT) group (P=0.001) and OBI group (P<0.001). The level of IL-18 in HBeAg negative group was significantly lower than that in HBeAg positive group (P=0.023). When HBV DNA load was ≥10(3) copies/ml, the level of IL-18 was significantly higher than that in HBsAg-negative group (P<0.01). With the increase of HBV DNA load in maternal blood, the level of IL-18 increased (P=0.024). When HBV DNA load was 10(3)-10(6) copies/ml, the level of IL-18 in DBI group was significantly lower than that in NBIT group (P=0.022), and increased with the increase of HBV DNA load in maternal blood (P=0.016). With the increased severity of intrauterine transmission of HBV, the level of IL-18 in non-hepatitis B vaccine group decreased significantly (P=0.044). The level of IL-18 in non-hepatitis B vaccine group and immunoglobulin injection group was significantly higher than that in NBIT group (P<0.05). Multivariate analysis showed that the linear relationship between maternal HBeAg status and maternal IL-18 levels had statistical significance (P=0.01). Conclusions: IL-18 is a higher level balance regulator of Th1/Th2 immune network. Monitoring the level of IL-18 in HBsAg-positive parturients can be used not only for predicting the probability of DBI and OBI, but also as an intervention mean, especially for those who are HBeAg-positive and had HBV DNA load ≥10(3) copies/ml, to improve maternal cellular immune function, which is conducive to interrupting intrauterine transmission and providing a theoretical basis for the prevention and control of HBV intrauterine transmission.

Abstract
Objective: To investigate the influence of IFN-γ and IL-12 levels in prenatal peripheral blood of HBsAg-positive parturients on intrauterine transmission of hepatitis B virus (HBV). Methods: A case-control study was conducted in 282 HBsAg positive parturients and 43 health parturients (control group) in Northwest Women and Children Hospital of Shaanxi Province. Enzyme-linked immunosorbent assay (ELISA) was used to detect five serological makers of hepatitis B in peripheral blood of parturients. HBV DNA was detected by real-time fluorescence quantitative PCR. Detection of cytokines IFN-γ and IL-12 levels were conducted with liquid chip-based flow cytometry method. The serum levels of five serological markers of hepatitis B and HBV DNA in 285 newborns were detected within 24 hours after birth. Results: The incidence of intrauterine dominant infection (DBI), occult infection (OBI) and intrauterine transmission of HBV in HBsAg positive parturients were 7.37% (21/285), 40.70% (116/285) and 48.07% (137/285), respectively. The level of IFN-γ in peripheral blood of HBsAg-negative parturients was significantly lower than those of HBsAg-positive parturients (t=-2.55, P=0.011), NBIT group (t=-2.54, P=0.012) and OBI group (t=-2.33, P=0.021). In HBV DNA load of 10(3)-10(6) copies/ml group, the levels of IFN-γ in the DBI group were significantly lower than those in OBI group and NBIT group (P<0.01). The level of IFN-γ in maternal peripheral blood decreased significantly with the increased severity of intrauterine transmission of HBV (χ(2)=6.40, P=0.041). In the antiviral treatment group, the level of IL-12 in maternal peripheral blood decreased significantly with the increased severity of intrauterine transmission of HBV (χ(2)=8.90, P=0.012). Multivariate analysis showed that there was a significant linear relationship between maternal IFN-γ level and maternal age, placenta previa and hepatitis B vaccine injection (P<0.05). The linear relationship between the level of maternal IL-12 and the mode of rupture and hepatitis B vaccine injection had statistical significance (P<0.05). Conclusions: HBV can stimulate the expression of IFN-γ and inhibit the secretion of IL-12 in pregnant and lying-in women, but the expression of IFN-γ in HBsAg-positive parturients showed intra-group differentiation, and the maternal level of IFN-γ will decrease in HBeAg-positive and high-HBV DNA loadstatus. Increasing the levels of IFN-γ and IL-12 in HBsAg-positive parturients is beneficial to block intrauterine transmission of HBV, especially DBI.

Abstract
Doctors and patients attempt to accelerate orthodontic tooth movement with a minimally invasive surgery approach. The purpose of this systematic review was to evaluate the evidence of accelerated tooth movement in minimally invasive surgery and the adverse effects from it. A systematic search of the literature was performed in the electronic databases of PubMed, CENTRAL (Cochrane Central Register of Controlled Trials), Embase, Scopus, Web of Science, Science Direct, and Medline and was complemented by a manual search until February 2019. The inclusion criteria were prospective clinical studies of patients treated with a fixed appliance, and the intervention was accelerated orthodontic treatment with minimally invasive surgery. Nineteen articles (538 participants) were included in the review: 9 studies assessed the rate of upper canine movement; 5 considered the treatment time; 1 evaluated the en masse retraction time; and 4 studied adverse effects. We performed a meta-analysis for the rate of canine movement and treatment time and described the results for the adverse effects in a systematic review. The results of the subgroup analysis according to micro-osteoperforation and piezocision were included in the study. No accelerated tooth movement was found in the micro-osteoperforation group. After flapless corticotomy procedures, increased tooth movement rates were identified by weighted mean differences of 0.63 (95%CI = 0.22, 1.03, P = 0.003) and 0.64 (95% CI, −25 to 1.53; P = 0.16) for 1 and 2 mo, respectively. The mean treatment time was 68.42 d (95% CI, −113.19 to −23.65; P = 0.003) less that than for minimally invasive surgery. Moreover, no significant adverse effect was found. Because of the high heterogeneity of the meta-analysis, the results must be validated by additional large-sample multicenter clinical trials. There is not sufficient evidence to support that the single use of micro-osteoperforation could accelerate tooth movement, and there is only low-quality evidence to prove that flapless corticotomy could accelerate tooth movement.
