Intimate relationships regulate female brain activity in a competitive context: evidence from EEG and functional connectivity analysis.

Competition is common in life, and intimate relationships are essential. Understanding how intimate relationships impact an individual's competitive process is crucial. This study explored the impact of competitor gender on female competition using electroencephalography analysis. The results revealed that females exhibited a smaller median of the absolute value of reaction time difference (DRT) between their partners and their competitors when their partners were absent compared to when their partners were present. Additionally, females showed greater average amplitudes of N2 posterior contralateral component (N2pc) and Late Positive Potential (LPP), increased activation of the alpha frequency band, and enhanced theta frequency band functional connectivity between the central parietal lobe and occipital lobe. Furthermore, when competing with individuals of the same gender as opposed to individuals of the opposite gender, females exhibited greater average amplitudes of percentage of wins and N2pc. A significant negative correlation was noted between the DRT and the average wave amplitudes of N2pc and LPP. These findings suggest that females are more engaged in competitive tasks when partners are not present and have improved decision-making when competing with same-gender individuals. This study provides evidence for the influence of lovers on female competition, helping females adapt to social competition and promoting healthy relationships.

Contribution of FOS in neutrophils to venous thromboembolism via miR-144 based on bioinformatic prediction and validation.

The Finkel-Biskis-Jinkins Osteosarcoma (c-Fos; encoded by FOS) plays an important role in several cardiovascular diseases, including atherosclerosis and stroke. However, the relationship between FOS and venous thromboembolism (VTE) remains unknown. We identified differentially expressed genes in Gene Expression Omnibus dataset, GSE48000, comprising VTE patients and healthy individuals, and analysed them using CIBERSORT and weighted co-expression network analysis (WGCNA). FOS and CD46 expressions were significantly downregulated (FOS p = 2.26E-05, CD64 p = 8.83E-05) and strongly linked to neutrophil activity in VTE. We used GSE19151 and performed PCR to confirm that FOS and CD46 had diagnostic potential for VTE; however, only FOS showed differential expression by PCR and ELISA in whole blood samples. Moreover, we found that hsa-miR-144 which regulates FOS expression was significantly upregulated in VTE. Furthermore, FOS expression was significantly downregulated in neutrophils of VTE patients (p = 0.03). RNA sequencing performed on whole blood samples of VTE patients showed that FOS exerted its effects in VTE via the leptin-mediated adipokine signalling pathway. Our results suggest that FOS and related genes or proteins can outperform traditional clinical markers and may be used as diagnostic biomarkers for VTE.

Cumulative effects of excess high-normal alanine aminotransferase levels in relation to new-onset metabolic dysfunction-associated fatty liver disease in China.

BACKGROUND: Within the normal range, elevated alanine aminotransferase (ALT) levels are associated with an increased risk of metabolic dysfunction-associated fatty liver disease (MAFLD). AIM: To investigate the associations between repeated high-normal ALT measurements and the risk of new-onset MAFLD prospectively. METHODS: A cohort of 3553 participants followed for four consecutive health examinations over 4 years was selected. The incidence rate, cumulative times, and equally and unequally weighted cumulative effects of excess high-normal ALT levels (ehALT) were measured. Cox proportional hazards regression was used to analyse the association between the cumulative effects of ehALT and the risk of new-onset MAFLD. RESULTS: A total of 83.13% of participants with MAFLD had normal ALT levels. The incidence rate of MAFLD showed a linear increasing trend in the cumulative ehALT group. Compared with those in the low-normal ALT group, the multivariate adjusted hazard ratios of the equally and unequally weighted cumulative effects of ehALT were 1.651 [95% confidence interval (CI): 1.199-2.273] and 1.535 (95%CI: 1.119-2.106) in the third quartile and 1.616 (95%CI: 1.162-2.246) and 1.580 (95%CI: 1.155-2.162) in the fourth quartile, respectively. CONCLUSION: Most participants with MAFLD had normal ALT levels. Long-term high-normal ALT levels were associated with a cumulative increased risk of new-onset MAFLD.

Association of the triglyceride-glucose index with the occurrence and recurrence of colorectal adenomas: a retrospective study from China.

BACKGROUND: Resection of colorectal adenoma (CRA) prevents colorectal cancer; however, recurrence is common. We aimed to assess the association of the triglyceride-glucose (TyG) index with CRA occurrence and recurrence. METHODS: Data from 3392 participants at a hospital in China from 2020 to 2022 were analyzed. Logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs). A restricted cubic spline was used to fit TyG index dose‒response curves to recurrent adenomas. The discriminatory power of TyG index for predicting later recurrence was assessed with the area under the receiver operating characteristic (ROC) curve in 170 patients with a TyG index at initial adenoma diagnosis. RESULTS: One thousand five hundred ninety-six adenoma and 1465 normal participants were included in the occurrence analysis, and 179 recurrent and 152 nonrecurrent participants were included in the recurrence analysis. The TyG mutation was an independent risk factor for CRA occurrence and recurrence. After adjusting for confounders, the risk of adenoma in the participants in Q2, Q3, and Q4 groups of TyG was 1.324 (95% CI 1.020-1.718), 1.349 (95% CI 1.030-1.765), and 1.445 (95% CI 1.055-1.980) times higher than that of the Q1, respectively, and the risk of recurrence in the Q3 and Q4 groups was 2.267 (95% CI 1.096-4.691) and 2.824 (95% CI 1.199-6.648) times in Q1 group. Multiple logistic regression showed that the highest quartile of the TyG index was associated with a greater risk of advanced adenoma recurrence (OR 4.456, 95% CI 1.157-17.164), two or more adenomas (OR 5.079, 95% CI 1.136-22.714 [after removal of TyG index extreme values]), and proximal colon or both adenomas (OR 3.043, 95% CI 1.186-7.810). Subgroup analysis revealed that the association was found to be present only in participants of all age groups who were either male or without obesity, hyperglycemia, hypertension, or dyslipidemia (p < 0.05). ROC curves illustrated that the TyG index had good predictive efficacy for identifying recurrence, especially for patients with two or more adenomas (AUC 0.777, 95% CI 0.648-0.907). CONCLUSIONS: An increase in the TyG index is associated with an increased risk of adenoma occurrence and recurrence, with a stronger association with the latter.

Whole exome sequencing discloses a pathogenic MTM1 gene mutation in a continuous polyhydramnios family in China: Case report and literature review.

Polyhydramnios can be caused by genetic defects at times. However, to establish an accurate diagnosis and provide a precise prenatal consultation in a given case is still a great challenge toward obstetricians. To uncover the genetic cause of polyhydramnios in the two consecutive pregnancies, we performed whole-exome sequencing of DNA for the second suffering fetuses, their parents, and targeted sanger sequencing of other members of this family. We discovered a hemizygous truncating variant in MTM1 gene, c.438_439 del (p. H146Q fs*10) in this Chinese family. In the light of the molecular discoveries, the fetus's clinical phenotype was considered to be a good fit for X-linked myotubular myopathy (XLMTM). There is no related research to the prenatal manifestations of MTM1-related XLMTM among Chinese population, and this is the first one to present. Though the etiology of polyhydramnios is complicated, WES may provide us with a creative avenue in prenatal diagnosis.

SUMO1-regulated DBC1 promotes p53-dependent stress-induced apoptosis of lens epithelial cells.

Deleted in breast cancer 1 (DBC1) was initially identified from a homozygously deleted region in human chromosome 8p21. It has been well established that DBC1 plays a dual role during cancer development. Depending on the physiological context, it can promote or inhibit tumorigenesis. Whether it plays a role in lens pathogenesis remains elusive. In the present study, we demonstrated that DBC1 is highly expressed in lens epithelial cells from different vertebrates and in retina pigment epithelial cells as well. Moreover, DBC1 is SUMOylated through SUMO1 conjugation at K591 residue in human and mouse lens epithelial cells. The SUMOylated DBC1 is localized in the nucleus and plays an essential role in promoting stress-induced apoptosis. Silence of DBC1 attenuates oxidative stress-induced apoptosis. In contrast, overexpression of DBC1 enhances oxidative stress-induced apoptosis, and this process depends on p53. Mechanistically, DBC1 interacts with p53 to regulate its phosphorylation status at multiple sites and the SUMOylation of DBC1 enhances its interaction with p53. Together, our results identify that DBC1 is an important regulator mediating stress-induced apoptosis in lens, and thus participates in control of lens cataractogenesis.

Matrine disrupts Nrf2/GPX4 antioxidant system and promotes hepatocyte ferroptosis.

Matrine (MT) is an alkaloid isolated from Sophora flavescens with various bioactivities and is widely used clinically. However, the broader its clinical use, the greater its toxicity concerns. We investigate the role of ferroptosis in MT-induced liver injury caused by an imbalance in the antioxidant pathway. Our results showed that MT could cause pathological changes in liver tissues and lead to a significant reduction in L02 cell viability. MT also reduced superoxide dismutase (SOD) and glutathione (GSH), increased malondialdehyde (MDA), reactive oxygen species (ROS), and lipid peroxidation levels, and disrupted iron homeostasis, leading to ferroptosis. In addition, MT decreased the protein levels of FTH, Nrf2, xCT, GPX4, HO-1 and ferroptosis suppressor protein 1 (FSP1) and increased the protein levels of TRF1 and DMT1, characteristic indicators of ferroptosis. Interestingly, the cytotoxic effects of MT were alleviated by ferroptosis inhibitor, Nrf2 agonist, or selenium supplementation. These results revealed that MT triggers hepatocyte ferroptosis by inhibiting the Nrf2/GPX4 antioxidant system.

HSP90ß prevents aging-related cataract formation through regulation of the charged multivesicular body protein (CHMP4B) and p53.

Cataract is a leading ocular disease causing global blindness. The mechanism of cataractogenesis has not been well defined. Here, we demonstrate that the heat shock protein 90ß (HSP90ß) plays a fundamental role in suppressing cataractogenesis. HSP90ß is the most dominant HSP in normal lens, and its constitutive high level of expression is largely derived from regulation by Sp1 family transcription factors. More importantly, HSP90ß is significantly down-regulated in human cataract patients and in aging mouse lenses, whereas HSP90ß silencing in zebrafish causes cataractogenesis, which can only be rescued by itself but not other HSP90 genes. Mechanistically, HSP90ß can directly interact with CHMP4B, a newly-found client protein involved in control of cytokinesis. HSP90ß silencing causes upregulation of CHMP4B and another client protein, the tumor suppressor p53. CHMP4B upregulation or overexpression induces excessive division of lens epithelial cells without proper differentiation. As a result, these cells were triggered to undergo apoptosis due to activation of the p53/Bak-Bim pathway, leading to cataractogenesis and microphthalmia. Silence of both HSP90ß and CHMP4B restored normal phenotype of zebrafish eye. Together, our results reveal that HSP90ß is a critical inhibitor of cataractogenesis through negative regulation of CHMP4B and the p53-Bak/Bim pathway.

Emodin disrupts the Notch1/Nrf2/GPX4 antioxidant system and promotes renal cell ferroptosis.

Emodin has been demonstrated to possess multiple pharmacological activities. However, emodin has also been reported to induce nephrotoxicity at high doses and with long-term use, and the underlying mechanism has not been fully disclosed. The current study aimed to investigate the roles of oxidative stress and ferroptosis in emodin-induced kidney toxicity. Mice were intraperitoneally treated with emodin, and NRK-52E cells were exposed to emodin in the presence or absence of treatment with Jagged1, SC79, or t-BHQ. Emodin significantly upregulated the levels of blood urea nitrogen, serum creatinine, malondialdehyde, and Fe2+ , reduced the levels of superoxide dismutase and glutathione, and induced pathological changes in the kidneys in vivo. Moreover, the viability of NRK-52E cells treated with emodin was reduced, and emodin induced iron accumulation, excessive reactive oxygen species production, and lipid peroxidation and depolarized the mitochondrial membrane potential (ΔΨm). In addition, emodin treatment downregulated the activity of neurogenic locus notch homolog protein 1 (Notch1), reduced the nuclear translocation of nuclear factor erythroid-2 related factor 2 (Nrf2), and decreased glutathione peroxidase 4 protein levels. However, Notch1 activation by Jagged1 pretreatment, Akt activation by SC79 pretreatment, or Nrf2 activation by t-BHQ pretreatment attenuated the toxic effects of emodin in NRK-52E cells. Taken together, these results revealed that emodin-induced ferroptosis triggered kidney toxicity through inhibition of the Notch1/Nrf2/glutathione peroxidase 4 axis.

Crosstalk between PML and p53 in response to TGF-ß1: A new mechanism of cardiac fibroblast activation.

Cardiac fibrosis is a common pathological cardiac remodeling in a variety of heart diseases, characterized by the activation of cardiac fibroblasts. Our previous study uncovered that promyelocytic leukemia protein (PML)-associated SUMO processes is a new regulator of cardiac hypertrophy and heart failure. The present study aimed to explore the role of PML in cardiac fibroblasts activation. Here we found that PML is significantly upregulated in cardiac fibrotic tissue and activated cardiac fibroblasts treated with transforming growth factor-ß1 (TGF-ß1). Gain- and loss-of-function experiments showed that PML impacted cardiac fibroblasts activation after TGF-ß1 treatment. Further study demonstrated that p53 acts as the transcriptional regulator of PML, and participated in TGF-ß1 induced the increase of PML expression and PML nuclear bodies (PML-NBs) formation. Knockdown or pharmacological inhibition of p53 produced inhibitory effects on the activation of cardiac fibroblasts. We further found that PML also may stabilize p53 through inhibiting its ubiquitin-mediated proteasomal degradation in cardiac fibroblasts. Collectively, this study suggests that PML crosstalk with p53 regulates cardiac fibroblasts activation, which provides a novel therapeutic strategy for cardiac fibrosis.

Juvenile hormone regulates photoperiod-mediated male reproductive diapause via the methoprene-tolerant gene in the ladybeetle Harmonia axyridis.

Juvenile hormone (JH) absence induces photoperiod-mediated reproductive diapause, which is characterized by reproductive cessation. Although the role of methoprene-tolerant (Met)-mediated JH signaling in photoperiod-mediated female reproduction has been well documented, its role in male reproduction remains unclear. In this study, we investigated the role of JH in regulating photoperiod-mediated development of the male internal reproductive system (IRS) in the predatory ladybeetle Harmonia axyridis (Pallas). In a previous study, we found that adult male H. axyridis reared under either a short-day (SD) or long-day (LD) photoperiod had obvious differences in IRS development, but we were unable to identify the regulators of male reproductive diapause. In this study, we found that beetles reared under an SD photoperiod had significantly lower JH titer and a relatively undeveloped male IRS compared with those reared under an LD photoperiod. Additionally, application of the JH analog (JHA) methoprene promoted IRS development. Furthermore, Met knockdown strongly blocked JH signaling in males reared under the LD photoperiod, thereby slowing IRS development. Moreover, exogenous JHA did not reverse the suppressed development of the male IRS caused by Met knockdown. These results indicate that photoperiod regulates male IRS development in H. axyridis through a conserved Met-dependent JH signaling pathway.

Primary breast cancer patient with poliomyelitis: A case report.

BACKGROUND: Poliomyelitis is an acute infection caused by an enterovirus, which primarily infects the human gastrointestinal tract. In general, patients with polio have no association with the occurrence of cancer. The present case study presents a rare case of poliomyelitis combined with primary breast cancer. CASE SUMMARY: A 61-year-old woman who was diagnosed with poliomyelitis at 5 years old and confirmed invasive breast cancer by core needle biopsy (CNB) after hospitalization. The patient received a modified radical mastectomy and four cycles of chemotherapy with the TC (docetaxel and cyclophosphamide) regimen. The patient was also prescribed endocrine therapy without radiotherapy after chemotherapy. The patient had no evidence of lymphedema in the right upper extremities and no evidence of either regression or distant metastasis at the 1-year follow-up. CONCLUSION: The pectoral muscles of patients with polio are easily damaged in traumatic procedures, such as CNB, local anesthesia for tumor excision, and general anesthesia for surgery. A CNB, modified radical mastectomy, and four cycles of TC chemotherapy were successfully completed for the present case and the adverse reactions were found to be tolerable. This case may indicate the relationship between breast cancer and polio, and the examination and treatment methods used could be used as a guide for similar cases in the future.

Ultrathin Densified Carbon Nanotube Film with "Metal-like" Conductivity, Superior Mechanical Strength, and Ultrahigh Electromagnetic Interference Shielding Effectiveness.

Flexible and lightweight high-performance electromagnetic interference shielding materials with minimal thickness, excellent mechanical properties, and outstanding reliability are highly desired in the field of fifth-generation (5G) communication, yet remain extremely challenging to manufacture. Herein, we prepared an ultrathin densified carbon nanotube (CNT) film with superior mechanical properties and ultrahigh shielding effectiveness. Upon complete removal of impurities in pristine CNT film, charge separation in individual CNTs induced by polar molecules leads to strong CNT-CNT attraction and film densification, which significantly improve the electrical conductivity, shielding performance, and mechanical strength. The tensile strength is up to 822 ± 21 MPa, meanwhile the electrical conductivity is as high as 902,712 S/m, and the density is only 1.39 g cm-3. Notably, the shielding effectiveness is over 51 dB with a thickness of merely 1.85 µm in the broad frequency range of 4-18 GHz, and it reaches to ∼82 dB at 6.36 µm and ∼101 dB at 14.7 µm, respectively. Further, such CNT film exhibits excellent reliability after an extended period in strong acid/alkali, high temperature, and high humidity. It demonstrates the best overall performance among representative shielding materials by far, representing a critical breakthrough in the preparation of shielding film toward applications in wearable electronics and 5G communication.

[Influence on orbicularis oculi muscle in the patients with facial neuritis treated with the penetra-ting needling at Cuanzhu (BL2) and Yuyao (EX-HN4) combined with the perpendicular needling at Shenmai (BL62)].

OBJECTIVE: To explore the therapeutic effect on incomplete eyelid in the patients with facial neuritis treated with the penetrating needling at Cuanzhu (BL2) and Yuyao (EX-HN4) combined with the perpendicular needling at Shenmai (BL62). METHODS: A total of 64 patients with facial neuritis, in compliance with the inclusion criteria, were randomized into a treatment group and a control group, with 32 cases in each. In the treatment group, the penetrating needling was applied to BL2 and EX-HN4 on the affected side, combined with the perpendicular needling at bilateral BL62. Besides, on the affected side, the penetrating needling was applied from Yangbai (GB14) toward four directions, named Shangxing (GV23), Touwei (ST8), Cuanzu (BL2) and Sizukong (TE23), the mutual penetrating needling was adopted between Dicang (ST4) and Jiache (ST6). Between Yingxiang (LI20) and Xiaguan (ST7), a row-arranged needling technique was applied. All of the needles were retained for 10 to 30 min in each treatment. The treatment was given once daily and the treatment for 10 days was as 1 course. A total of 2 courses of treatment were required. In the control group, prednisone acetate （30 mg/d）, was administered consecutively for 5 days. Afterward, the dose was reduced to be 10 mg/d and the medication stopped after taking consecutively for 1 week. Muscular injection with vitamin B12 （0.5 mg） and B1 （0.1 mg） was given, once daily. 10 days later, vitamin B1 was taken for oral administration, 10 mg each time, three times a day, for 10 days totally. Before and after the treatment, the clinical effect was compared between the two groups in terms of the analysis on the Hourse-Brackman (H-B) grade of facial nerve function, the distance between the upper and the lower eyelids, muscle strength, degree of eyelid closure and electromyogram (EMG). RESULTS: The total effective rate of treatment group was 96.9 % (31/32), better than 84.4%（27/32） in the control group (P<0.05). After treatment, in the treatment group, the distance between the upper and lower eyelids, the muscle strength, the degree of eyelid closure, the wave amplitude of motor nerve conduction and the latent period, as well as the blink reflex were all improved as compared with those before the treatment (P<0.01, P<0.05). In the control group, the distance between the upper and lower eyelids, the muscle strength, the degree of eyelid closure, the latent period of motor nerve conduction and the blink reflex were all improved as compared with those before the treatment (P<0.01, P<0.05). After the treatment, the results of the distance between the upper and lower eyelids, the muscle strength, the degree of eyelid closure, the wave amplitude of motor nerve conduction and the latent period, as well as the blink reflex in the treatment group were all better than those in the control group (P<0.05，P<0.01). CONCLUSION: The treatment with the penetrating needling at Cuanzhu (BL2) and Yuyao (EX-HN4) combined with the perpendicular needling at Shenmai (BL62) greatly promotes the recovery of orbicularis oculi muscle in the patients with facial neuritis, reduces the complications and presents the satisfactory clinical effect.

[Jingjin needling improves facial nerve function and psychosomatic function in Hunt facial para-lysis patients].

OBJECTIVE: To observe the clinical effectiveness of Jingjin (muscle region) needling in the treatment of Hunt facial paralysis (HFP). METHODS: A total of 80 HFP patients were randomly divided into acupuncture and medication groups (n＝40 cases/group). Jingjin needling was applied to Yangbai(GB14) to Shangxing (GV23), Touwei (ST8), Cuanzhu (BL2), Sizhukong (TE23，penetrative needling), Dicang (ST4) to Jiache (ST6, penetrative needling), Yingxiang(LI20) and Xiaguan(ST7), Hegu(LI4), Yifeng (TE17), Yuyao (EX-HN 4), and Shenmai (BL62), with the needles retained for 30 min. The treatment was conducted once daily, with 10 consecutive days being a therapeutic course, and 3 courses altogether. Patients of the medication group received oral administration of Prednisone acetate (12 days), Acyclovir (7 days), intramuscular injection of Vitamin B12 and Vitamin B1(10 days), then, oral administration of Vitamin B1, successively. The therapeutic effect was assessed by using House-Brackman (H-B) facial function grading system (grade I to VI), traditional Chinese medicine (TCM) sign and symptom score, and facial disability index (FDI) scale including FDI physical function (FDIP, food and water swallowing, speaking-pronouncing, dryness or tearing, and mouth-opening) and FDI social function (FDIS, self-rating anxiety/depression scales), separately. RESULTS: After the treatment, the TCM symptom and sign scores for depth of nasolabial groove, nose shrugging, lower lip asymmetry, food retention and post-auricular pain were significantly lower in the medication group (P<0.05)．After the treatment, the TCM symptom and sign scores for frontal muscle movement, eyelid opening and closing, depth of nasolabial groove, nose shrugging, lower lip asymmetry, cheek blowing, food retention, latissimus cervicalis contraction, taste disorder, hearing hypersensitivity, tears and discomfort and post-auricular pain were significantly lower in the acupuncture group (P<0.05)．Comparison between two groups showed that the TCM symptom and sign scores for frontal muscle movement, eyelid opening and closing, depth of nasolabial groove, nose shrugging, lower lip asymmetry, cheek blowing, food retention, latissimus cervicalis contraction, taste disorder, hearing hypersensitivity, tears and discomfort and post-auricular pain were significantly lower in the acupuncture group than in the medication group(P<0.05)．The scores of FDIP and FDIS were significantly increased in both groups (P<0.01) and notably higher in the acupuncture group than in the medication group (P<0.01) after the treatment. The total effective rate of acupuncture group was 97.5% (39/40), and that of medication group was 72.5% (29/40). The therapeutic effect of the acupuncture group was significantly superior to that of the medication group (P<0.01)．. CONCLUSION: Jingjin needling has a good therapeutic effect in improving facial nerve function, psychosomatic function and clinical signs and symptoms in HFP patients, evidently being better than medication.

Up-regulated lnc-lung cancer associated transcript 1 enhances cell migration and invasion in breast cancer progression.

Breast cancer remains a leading cause of tumor-related deaths in the world. The pathogenesis contributing to breast cancer progression has not been fully understood. Increasing evidence suggests that long noncoding RNA (lncRNA) is implicated in various kinds of malignant cancers, including breast cancer. In the study, we attempted to explore the expression and effects of lnc-lung cancer associated transcript 1 (LUCAT1) on breast cancer development. Our results indicated that the expression of lnc-LUCAT1 was highly up-regulated in breast cancer tissues and cell lines. Over-expression of lnc-LUCAT1 enhanced cell proliferation, migration and invasion in breast cancer cell lines. Moreover, lnc-LUCAT1 was found to be a target of miR-7-5p. There was a negative correlation between lnc-LUCAT1 and miR-7-5p. The reduction of miR-7-5p was required in the augmentation of breast cancer development induced by lnc-LUCAT1 over-expression. In addition, SOX2 acted as a target of miR-7-5p. SOX2 was an oncogene in breast cancer through promoting cell proliferation, migration and invasion. The in vivo study confirmed the role of lnc-LUCAT1 in promoting tumor growth, accompanied with down-regulated SOX2 expression, whereas up-regulated miR-7-5p. Collectively, the lnc-LUCAT1/miR-7-5p-SOX2 regulatory pathway might provide a new and effective therapeutic strategy to prevent breast cancer development.

Differences in the Development of Internal Reproductive Organs, Feeding Amount and Nutrient Storage between Pre-Diapause and Pre-Reproductive Harmonia axyridis Adults.

Diapause control is one of the successful methods for long-term cold storage of biological control organisms without decreasing their fitness. Sufficient preparation before diapause is essential for successful diapause initiation and maintenance. Harmonia axyridis, an important biocontrol agent in its native place, can enter reproductive diapause for overwintering. However, the key preparatory events before diapause in H. axyridis, such as specific developmental trajectory, timing, and physiological changes, remain unclear. We compared differences in the development of internal reproductive organs, feeding amount and nutrient storage between pre-diapause and pre-reproductive adult H. axyridis which had been reared at 20 °C under a short-day (10L:14D) and long-day (14L:10D) condition, respectively. The results showed that there were obvious morphological differences in internal reproductive organs of diapause and reproductive H. axyridis. The development of internal reproductive organs was suppressed at early adult stage in pre-diapause beetles compared to pre-reproductive beetles. Feeding amount in both pre-diapause and pre-reproductive beetles increased for more than ten days after eclosion. The feeding amount of pre-diapause beetles sharply decreased from the 15th day after eclosion in females and the 14th day after eclosion in males, which implied the initiation of diapause. During the pre-diapause stage, carbohydrates and lipids were mainly accumulated by females, whereas males mainly accumulated carbohydrates. Our results not only provide basic information about the diapause process of pre-diapause stage, but also give tips to better utilization of diapause strategy during mass production and storage of H. axyridis.

Effects of prophylactic uterine artery embolization on second-trimester induced abortions in patients with placenta previa.

OBJECTIVE: To evaluate the effects of prophylactic uterine artery embolization (UAE) on second-trimester induced abortions in patients with placenta previa. METHODS: The present study was a retrospective review of second-trimester induced abortions in the presence of placenta previa that conducted between January 1, 2008, and October 31, 2017, at a university hospital in Hangzhou, China. Pregnancy outcomes including intraoperative blood loss, transfusion, dilatation and evacuation, hysterotomy delivery, and hysterectomy were compared between patients with and without prophylactic UAE. RESULTS: There were 54 patients included in the study. In patients with partial placenta previa (n=15), the volume of intraoperative blood loss and the frequency of dilatation and evacuation were not significantly different between the UAE and non-UAE groups (P>0.05). No patient had a transfusion, hysterotomy delivery, or hysterectomy. Among patients with complete placenta previa (n=39), the volumes of intraoperative blood loss (P=0.014) and transfusion (P=0.046) were significantly lower in the UAE group compared with the non-UAE group. The rates of dilatation and evacuation, and hysterotomy delivery did not differ between the groups (P>0.05), but were numerically higher in the non-UAE group. No patient was treated with hysterectomy. CONCLUSION: Prophylactic UAE before a second-trimester induced abortion had significant advantages in women with complete placenta previa, but it did not improve the pregnancy outcome in patients with partial placenta previa.
