Abstract
Obesity has become one of the most serious public health problems worldwide, and an increasing number of studies indicate that the gut microbiota can affect host metabolism. Therefore, the present study was conducted to evaluate whether long-term use of probiotics can alleviate host obesity and metabolism by altering gut microbiota. The high-fat diet (HFD) starting from weaned period led to higher levels of visceral fat and a significantly heavier liver in male mice. Moreover, HFD resulted in disorders of glucose and lipid metabolism, changes in insulin-resistance indices (IR), and an increase in serum insulin and leptin in mice. Of note, 15 weeks use of Lacticaseibacillus paracasei N1115 decreased visceral fat, liver weight, serum levels of insulin and leptin, and IR and alleviated lipid dysmetabolism. HFD resulted in a significant increase in the relative abundance of Bilophila, Lachnoclostridium, and Blautia and may decrease the faecal short-chain fatty acid (SCFA) levels in mice; in turn, treatment with the potential probiotic strain L. paracasei N1115 protected mice from these negative effects. HFD significant impaired the physiology of the host especially in male mice and dramatically changed the composition of host gut microbiota. However, the use of potential probiotic strain, such as L. paracasei N1115, may prevent these impairments due to HFD via effecting the host gut microbiota and SCFA.

Abstract
Objective: Functional near-infrared spectroscopy (fNIRS) was used to study the effect of aging on the neuroimaging characteristics of cerebral cortex in the process of speech perception. Method: Thirty-four adults with normal hearing were recruited from March 2021 to June 2021, including 17 in the young group, with 6 males, 11 females, age (32.1±5.0) years, age range 20-39 years. and 17 in the elderly group, with 6 males, 11 females, age (63.2±2.8) years, age range 60-70 years. The test material was the sentence table of the Mandarin Hearing Test in Noise (MHINT). The task state block experiment design was adopted, and the temporal lobe, Broca's area, Wernicke's area, motor cortex were used as regions of interest. Objective brain imaging technology (fNIRS) combined with subjective psychophysical testing method was used to analyze the activation area and degree of cerebral cortex related to auditory speech perception in the elderly and young people under different listening conditions (quiet, signal-to-noise ratio of 10 dB, 5 dB, 0 dB, -5 dB). SPSS 23 software was used for statistical analysis. Result: The activation area and degree of activation in the elderly group were lower than those in the young group under each task condition; The number of activation channels in the young group were significantly more than those in the old group, and the number of activation channels in the left hemisphere were more than those in the right hemisphere, but there was no difference in the number of activation channels. There were more channels affected by age in the left hemisphere than in the right hemisphere. The activation degree of the young group when the signal-to-noise ratio was 0 dB was significantly higher than that of other signal-to-noise ratio conditions (P<0.05), but there was no significant difference in the old group under the five conditions (P>0.05). The speech recognition score of the young group was higher than that of the old group under all conditions. When the quiet and signal-to-noise ratio was 10 dB, the correct score of the two groups was equal or close to 100%. With the gradual decrease of signal-to-noise ratio, there was a significant difference between the two groups when the signal-to-noise ratio was 5 dB. The speech recognition accuracy of the young group decreased significantly when the signal-to-noise ratio was 0 dB, while that of the old group decreased significantly when the signal-to-noise ratio was 5 dB. Conclusions: With the increase of age, the speech perception in noisy environment and the activity of cerebral cortex gradually deteriorate, and the speech dominance hemisphere (left hemisphere) will be significantly affected by aging. The overall activation area and activation degree of the elderly under different speech tasks are lower than those of the young.

Abstract
Objectives: To investigate the prevalence and associated risk factors of tinnitus in Sichuan and Chongqing. Methods: We designed a tinnitus epidemiological questionnaire. The multi-stage stratified cluster random sampling methods was applied to obtain study subjects in six areas (Nanchong, Jiangjin, Fengdu, Yunyang, Suining and Ya'an), which were selected for epidemiological investigation. Home visit completion of epidemiological questionnaires was conducted. The trained investigators guided the respondents to fill in the tinnitus epidemiological questionnaires, and the epidemiological status of six areas on prevalence and risk factor was investigated. SPSS 22.0 software was used for statistical analysis. Results: Sampling population were 10 289, in which 9 273 were valid questionnaires. There were 4 281 males and 4 992 females, with an average age of 47.3 years, among which 34.83% (3 230/9 273) had tinnitus. 3.99% (370/9 273) were diagnosed with bothersome tinnitus. In a multivariable logistic regression mod, the following factors were associated with onsetting of tinnitus: sleep disorder [Odds Ratio(OR)=3.74] and noise exposure(OR=1.99). The risk of disease was lowest in the age of 30-40 years old, while the risk of disease was higher for people under 30 and over 40. In another multivariable logistic regression mode, the following factors were associated with having bothersome tinnitus: older people were more likely to suffer from tinnitus, sleep disorders (OR=4.68) and noise exposure (OR=1.56). Conclusions: The prevalence of tinnitus in Sichuan and Chongqing is about 34.83%, but most of the tinnitus is short-lived and has low loudness, which will not affect the patients. Only a small number of patients with tinnitus (3.99%) persist and affect their health and need treatment. The occurrence and exacerbation of tinnitus may be related to sleep, age, and noise exposure.

Abstract
Model organism research is essential for discovering the mechanisms of human diseases by defining biologically meaningful gene to disease relationships. The Rat Genome Database (RGD, ( https://rgd.mcw.edu )) is a cross-species knowledgebase and the premier online resource for rat genetic and physiologic data. This rich resource is enhanced by the inclusion and integration of comparative data for human and mouse, as well as other human disease models including chinchilla, dog, bonobo, pig, 13-lined ground squirrel, green monkey, and naked mole-rat. Functional information has been added to records via the assignment of annotations based on sequence similarity to human, rat, and mouse genes. RGD has also imported well-supported cross-species data from external resources. To enable use of these data, RGD has developed a robust infrastructure of standardized ontologies, data formats, and disease- and species-centric portals, complemented with a suite of innovative tools for discovery and analysis. Using examples of single-gene and polygenic human diseases, we illustrate how data from multiple species can help to identify or confirm a gene as involved in a disease and to identify model organisms that can be studied to understand the pathophysiology of a gene or pathway. The ultimate aim of this report is to demonstrate the utility of RGD not only as the core resource for the rat research community but also as a source of bioinformatic tools to support a wider audience, empowering the search for appropriate models for human afflictions.

Abstract
Objective: To analyze the characteristics of magnetic resonance imaging (MRI) and clinical etiology of ovarian infertility. Methods: The data of infertile women who underwent 3.0T MRI and magnetic resonance hysterosalpingography (MR-HSG) examination in the Affiliated Hospital of Nanjing University of Chinese Medicine from September 2017 to March 2020 were collected. The ovarian factors of infertility, as well as the abnormalities of bilateral fallopian tubes and uterus, were evaluated. Etiologies assessed by MRI were finally confirmed by hysteroscopy, laparoscopy, surgery, or a comprehensive clinical diagnosis. Results: Among 1 351 patients, 1 296 cases were eligible and included for further analysis. Evaluated by MRI and MR-HSG, 494(38.12%) cases had ovarian abnormalities, including 239(48.38%) cases of ovarian endometriosiss, 116(23.48%) cases of polycystic ovary syndrome (PCOS), 37(7.49%) cases of diminished ovarian reserve (DOR), 33(6.68%) cases of ovarian mass, 28(5.67%) cases of ovarian injury, and 41(8.30%) cases who had at least two kinds of ovarian diseases. Unilateral and bilateral ovarian abnormalities accounted for 52.02% (257/494) and 47.98%(237/494), respectively.In total, 453 of 494(91.7%) patients had only one kind of ovarian disease. Among the 494 patients, 103(20.85%) cases had abnormal ovary with normal uterus and fallopian tubes, and the other 391(79.15%) cases had abnormalities not only in ovary, but in fallopian tube and/or uterus. Conclusion: Infertility-related ovarian diseases have certain characteristics of MRI findings. 3.0T MRI is useful for comprehensive analysis of etiology in ovarian infertility. Combined with MR-HSG, it provides one-stop assessments of the pelvic factors in female infertility.

Abstract
Abstract Objective To observe the skin ultrastructure change of electric shock death rats and to test the expression changes of hypoxia-inducible factor-2α (HIF-2α) and heart type-fatty acid-binding protein (H-FABP) of myocardial cells, in order to provide basis for forensic identification of electric shock death. Methods The electric shock model of rats was established. The 72 rats were randomly divided into control group, electric shock death group and postmortem electric shock group. Each group was divided into three subgroups, immediate (0 min), 30 min and 60 min after death. The skin changes of rats were observed by HE staining, the changes of skin ultrastructure were observed by scanning electron microscopy, and the expression of HIF-2α and H-FABP in rats myocardium was tested by immunohistochemical staining. Results The skin in the electric shock death group and postmortem electric shock group had no significant difference through the naked eye or by HE staining. Under the scanning electron microscope, a large number of cellular debris, cells with unclear boundaries, withered cracks, circular or elliptical holes scattered on the cell surface and irregular edges were observed. A large number of spherical foreign body particles were observed. Compared with the control group, the expression of HIF-2α in all electric shock death subgroups increased, reaching the peak immediately after death. In the postmortem electric shock group, HIF-2α expression only increased immediately after death, but was lower than that of electric shock death group (P<0.05). Compared with the control group, the expression of H-FABP in all subgroups of electric shock death group and postmortem electric shock group significantly decreased. The expression of H-FABP in all subgroups of electric shock death group was lower than that of the postmortem electric shock group (P<0.05). Conclusion Electric shock can increase HIF-2α expression and decrease H-FABP expression in the myocardium, which may be of forensic significance for the determination of electric shock death and identification of antemortem and postmortem electric shock.

Abstract
Rhopalosiphum padi is a worldwide agricultural pest. Chemosensory proteins (CSPs) are considered to be a type of transporters which can bind chemicals from external environments. Previous research showed that the expression of some insect CSPs were significantly increased after exposure to insecticides, and CSPs were involved in insecticide resistance or susceptibility. However, the role of CSPs in the susceptibility and response of R. padi to insecticides is still unknown. In this study, we identified eight CSP (RpCSP) from R. padi by genome-wide investigation. Seven RpCSP genes had two exons, while RpCSP7 had three exons. qPCR analyses showed that the mRNA levels of the eight RpCSP genes were significantly affected by imidacloprid and beta-cypermethrin in different post-treatment periods. Molecular docking predicted that there were hydrogen bonding sites which played key roles in binding of RpCSP4, RpCSP5, RpCSP6, RpCSP7 and RpCSP10 with imidacloprid and beta-cypermethrin. Knockdown of RpCSP4, RpCSP5, RpCSP6 and RpCSP10 by RNA interference significantly increased the aphid mortality under two sublethal concentrations of imidacloprid. Mortalities under two sublethal concentrations of beta-cypermethrin conditions were significantly higher after injection of R. padi with dsCSP4 and dsCSP6. The results indicate that some RpCSP genes are involved in the insecticide susceptibility of R. padi.

Abstract
Abstract Objective To explore the characteristics of individuals with mental disorders suspected of road traffic offences and to find their differences from normal offenders, in order to regulate mental disorder patients' driving activities and prevent road traffic offences. Methods One hundred and twenty-three cases of forensic psychiatry testimony of individuals suspected of road traffic offences between 2014 and 2019 from the West China Forensic Center of Sichuan Province were collected. Fisher exact probability test was used to compare the differences between offenders with mental disorders and without mental disorders in terms of demographic characteristics, criminological characteristics, psychiatric characteristics and criminal responsibilities. Results There was no statistical significance in the differences of demographic characteristics, vehicles and kinds of alcohol between the two groups (P>0.05). The main type of road traffic related crimes committed by offenders with mental disorders was risky driving and were mainly evaluated as partial criminal responsibility, whereas most offenders without mental disorders committed crime of causing traffic casualties and all were evaluated as full criminal responsibility. There was statistical significance in the differences of the types of crime and the criminal responsibility rating between the two groups (P<0.05). Meanwhile, patients with mental disorders were characterized by long course of disease and irregular treatment, and individuals diagnosed as having mental disorders caused by psychoactive substances accounted for a large proportion. Conclusion There are differences in the characteristics of road traffic-related crimes between mental disorder patients and normal people. It is of great practical significance for reducing road traffic offences to evaluate whether the individuals with mental disorders are fit for driving.

Abstract
Objective: To analyze the clinical characteristics and identify the causative gene of a case with congenital deafness. Methods: Detailed medical history and clinical examination of a 4-year-old male child with congenital deafness were conducted in the First Affiliated Hospital of Army Military Medical University in June 2016. He was diagnosed with sensorineural deafness. The venous blood of the child and his parents was drawn, and genomic DNA was extracted. Proband's DNA was performed with targeted capture of high-throughput sequencing, then Sanger sequencing was used to verify the suspected mutation and segregation in this pedigree. According to the genetic diagnosis of the proband's deafness, ophthalmic examinations were performed. Genetic prenatal diagnosis was performed when the proband's mother was pregnant again. Results: The patient was detected with p.Trp1466Ter/p.Tyr2042Ter compound heterozygous mutations of MYO7A gene with targeted high-throughput sequencing. The mutation of p.Trp1466Ter was a reported mutation, while p.Tyr2042Ter has not been reported. In addition to congenital deafness, retinitis pigmentosa was also found by ophthalmologic examination, and the patient was clinically diagnosed with Usher syndrome type 1. Amniocentesis and fetal DNA sequencing were performed on the repregnancy fetus of this family at 18 weeks of gestation. The heterozygous mutation of MYO7A gene p.Tyr2042Ter was found, and the other allele was the wild type, indicating that the child will not exhibit clinical manifestations of Usher syndrome type 1. Indeed, the second child passed neonatal hearing screening. Conclusions: The clinical features and genetic variants were delineated in this family with Usher syndrome type 1. The results of the current study have enriched the phenotype and genotype data of the disease and provided a basis for genetic counseling.

Abstract
Objective: To establish a clustered management plan for pulmonary care of massive burn casualties (hereinafter referred to as the clustered management plan for pulmonary care), and to explore its application effects. Methods: (1) A clustered care intervention group was established, including the medical and nursing staff from the Department of Burns and Plastic Surgery, Department of Respiratory Medicine, and Department of Infection Control at the Fourth Medical Center of PLA General Hospital (hereinafter referred to as our hospital). Four major links, including pulmonary care assessment, chest and lung physical therapy, artificial airway management, and specialized infection control were sorted out according to the key points and difficulties in pulmonary care for massive burn casualties. Evidence-based nursing methods were employed to retrieve articles related to the above-mentioned four links from PubMed, Chinese Journal Full-Text Database, VIP Database and Wanfang Data using terms of " mass burn, respiratory management and airway management" and terms of ",," , and the clustered management plan for pulmonary care was established based on reading and discussion in combination with clinical practice and experience. (2) In this non-randomized controlled study, the clustered management plan for pulmonary care was applied to 73 massive burn patients (48 males and 25 females, aged 32 (25, 38) years) who were admitted to our hospital from January 2016 to December 2019 and met the inclusion criteria, and they were included into the clustered care group; 43 massive burn patients (25 males and 18 females, aged 35 (17, 45) years) who were admitted to our hospital from January 2013 to December 2015, received routine care and met the inclusion criteria were retrospectively included into routine care group. The pulmonary infection rate and mortality of patients in the two groups were recorded during the hospital stay. Data were statistically analyzed with chi-square test, Mann-Whitney U test, and independent sample t test. Results: (1) The clustered management plan for pulmonary care included a total of 12 specific measures covering four aspects of pulmonary care. The contents in pulmonary care assessment clearly stated to include the previous medical history, history of injury, respiratory status, hoarseness, pulmonary auscultation, etc. Chest and lung physical therapy included how to guide patients to effectively cough and do pursed lip breathing and abdominal breathing exercise, etc. Artificial airway management specified the preparation for the establishment of artificial airway at clinical reception, the observation index and frequency after tracheotomy, the method of humidification, the method and frequency of sputum suction, and the management of mechanical ventilation, etc. Specialized infection control required to strengthen hand hygiene and ventilator management. (2) The pulmonary infection rate and mortality of patients in the clustered care group were 2.74% (2/73) and 4.11% (3/73), respectively, significantly lower than 25.58% (11/43) and 18.60% (8/43) in routine care group (χ(2)=11.986, 5.043, P<0.05 or P<0.01). Conclusions: The clustered management plan for pulmonary care developed for massive burn casualties focuses on the major links and key points. The measures are systemic and comprehensive, simple but precise, and highly operable, covering the entire process of massive burn care, hereby reducing the pulmonary infection rate significantly and improving the success rate of treatment.

Abstract
Objective: To explore the associations between perceived built environment attributes and adults' leisure-time physical activity in four cities of China. Methods: Multistage cluster random sampling method was used to select adults aged 25 to 64 in Hangzhou, Suzhou, Chengdu, and Qingdao. Data were collected from June 2017 to July 2018. The perception of the urban built environment was assessed by the neighborhood environment walkability scale-abbreviated (NEWS-A), and the physical activity was assessed by the International Physical Activity Questionnaire. Generalized linear mixed models were used to explore the relationship between the perceived built environment and leisure-time physical activities. Results: A total of 3 789 participants were included in the analysis. After adjusting for potential confounders, better access to public services (OR=1.34, 95%CI: 1.02-1.75) and higher aesthetic quality (OR=1.37, 95%CI: 1.09-1.73) were positively associated with the possibility of engaging in leisure-time physical activity in the past week. Similarly, these two attributes were positively associated with leisure-time walking. Higher scores on the perception of street connectivity were positively associated with leisure-time walking [exp(β)=1.09, 95%CI: 1.00-1.19]. Higher residential density [exp(β)=1.000 4, 95%CI:1.000 0-1.000 8], better access to physical activity destinations[exp(β)=1.09, 95%CI: 1.00-1.19], and better aesthetics [exp(β)=1.11, 95%CI:1.00-1.22] were associated with higher leisure-time physical activity. Similarly, these three attributes were positively associated with the possibility of meeting the WHO recommendations. Conclusion: Changing some urban built environment attributes may increase leisure-time physical activity.

Abstract
Objective: To explore the possible pathogenesis of central paroxysmal positional vertigo (CPPV) by analyzing its clinical manifestations and characteristics. Methods: The clinical data of 3 patients with CPPV, including 1 male and 2 females, aged 36, 14 and 70 years old respectively, were collected from the Department of Otorhinolaryngology, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences from June 2014 to June 2018. The clinical symptoms, nystagmus, other central ocular motor abnormalities, MRI, PET-CT, and laboratory findings were analyzed retrospectively. Results: All patients showed transient vertigo and nystagmus induced by head changes relative to gravity, but the characteristics of nystagmus did not conform to the typical characteristics of nystagmus in benign paroxysmal positional vertigo. None of patients response to repositioning maneuvers, and all patients presented with the signs of abnormal visual oculomotor system or other symptoms of central system. MRI, PET-CT and blood biochemical tests confirmed that the causes of CPPV in the patients were chronic hemorrhage, inflammation and paraneoplastic cerebellar degeneration. Although the etiology of the three cases is different, the lesion site is involved in the central velocity storage mechanism. Conclusion: The damage of central velocity storage mechanism may lead to the damage of feedback rotation signal correction pathway, and CPPV appears when the head position changes relative to gravity.

Abstract
Objective: To investigate the clinical characteristics and imaging manifestations of primary bone lymphoma (PBL) located in the jaw. Methods: Clinical data of 14 PBL patients admitted to The First Affiliated Hospital of Zhengzhou University from January 2014 to April 2019 were retrospectively analyzed, which including age, gender, location, chief complaint, laboratory test, imaging manifestations and so on. Results: Among the 14 PBL patients, 10 were male and 4 were female. Age range from 4 to 79 years, median age was 56 years old. There were 6 cases involved maxillary, 7 cases involved mandible and 1 case involved mandible and maxillary simultaneously. Twelve patients were admitted with local mass as the chief complaint, 3 had a history of toothache, 4 had loosen tooth and 2 had numbness of lips and cheeks. Two cases of oral mass with mucosal surface ulcer or abscess formation. One case complained of fever, night sweats and other systemic symptoms. The imaging findings showed 8 cases of osteolytic lesions, 1 case of sclerosis, 4 cases of mixed lesions and 1 case of cystic lesions. One case had periosteum reaction. In 12 cases, there was an obvious mass, which was characterized by the large soft-tissue mass and marrow changes were associated with surprisingly little cortical destruction. Conclusions: PBL is more common in middle aged male. The upper and lower jaw bones can be involved. Clinical and imaging manifestations lack characteristics, and common dental or periodontal symptoms such as toothache, tooth loosening, and paresthesia may occur. However, the imaging characteristics of large soft tissue masses with small degree of bone destruction can be used as an important basis for the differential diagnosis of osteomyelitis, squamous cell carcinoma, osteosarcoma and other diseases.

Abstract
BACKGROUND The efficacy of topical rapamycin is well documented for tuberous sclerosis complex (TSC)-related facial angiofibromas (FAs). Calcitriol has been shown to lessen skin fibrosis and may be therapeutically beneficial to FAs. OBJECTIVES To evaluate whether topical rapamycin-calcitriol combination is an effective and safe treatment for TSC-related FAs. METHODS Fifty-two patients with TSC with FAs were enrolled in this prospective study including three 12-week periods. In period 1, either topical rapamycin 0·1% or calcitriol 0·0003% single-agent therapy vs. their combination was applied in a double-blind, left-right-randomized, split-face comparison. The primary outcome was the reduction of modified Facial Angiofibroma Severity Index (mFASI) at week 12. In period 2, the patients were reassigned to use on both cheeks the ointment that resulted in the better primary outcome in period 1. The treatment was discontinued in period 3 (week 25-36) and a follow-up mFASI was scored to evaluate the degree of recurrence. RESULTS The mean changes in mFASI at week 12 compared with baseline were -0·92, -0·44 and -1·09 for rapamycin (P ≤ 0·001), calcitriol (P = 0·039) and rapamycin-calcitriol combination (P ≤ 0·001), respectively. Although rapamycin-calcitriol combination and rapamycin had similar statistically significant decreases of mFASI at week 12, rapamycin-calcitriol combination resulted in faster improvement in erythema, greater reduction of papule elevation and longer durability after discontinuing treatment than rapamycin alone. The treatments were well tolerated. CONCLUSIONS This randomized clinical trial demonstrates that topical rapamycin-calcitriol combination therapy is an effective and safe regimen for TSC-related FAs. What is already known about this topic? Facial angiofibromas (FAs) cause substantial psychological distress in individuals with tuberous sclerosis complex (TSC), but invasive procedural treatments are not applicable to all patients. Topical rapamycin has been demonstrated as an effective and safe treatment regimen for TSC-related FAs. What does this study add? Compared with baseline (day 0), both topical rapamycin 0·1% and rapamycin 0·1%-calcitriol 0·0003% combination ointment achieved statistically significant reductions in modified Facial Angiofibroma Severity Index at week 12. Compared with rapamycin alone, extended use of the rapamycin-calcitriol combination regimen until week 24 showed more effectiveness in decreasing papule elevation and could maintain a longer therapeutic effect after treatment discontinuation.

Abstract
Abstract
Background
Tuft cells are a rare chemosensory population of the intestinal epithelium that detect intestinal parasitic nematodes and release IL-25 to mobilize innate lymphoid type 2 cells (ILC2), which then drive a Th2- dominant nematode expulsion response. Immunocompetent mice develop tuft cell hyperplasia in the small intestine during infection with Hymenolepis diminuta, a non-abrasive lumen dwelling small intestinal cestode parasite. Helminth infections are accompanied by alterations in sensory motor functions of the gut as well as the composition of the microbiota. It is poorly understood if tuft cell hyperplasia is regulated by these immunomodulatory influences.
Aims
To test if mice lacking (1) a functional adaptive immune system, (2) TRPV1+ gut-innervating sensory nerves and (3) a microbiome, display enteric tuft cell hyperplasia following infection with H. diminuta.
Methods
RAG-1-/- (male and female) and germ-free mice (n=3–6) were infected with 5 cysticercoids of H. diminuta and age matched non-infected mice served as control groups. Male C57BL/6j mice were treated with resiniferatoxin (RTX) to ablate TRPV1 +sensory neurons before infection. Mid-jejunum cryostat or paraffin embedded sections immunostained against doublecortin-like kinase -1 (DCLK-1) were blindly scored for tuft cell enumeration at 5–14 days post-infection.
Results
Tuft cell hyperplasia (~10-15-fold increase) was observed in the jejunum of wild-type mice at 11 days post infection with H. diminuta, by which time worms are expelled. Infected RAG-1-/- mice develop tuft cell hyperplasia of lesser magnitude than wild-type mice. Germ-free mice displayed tuft cell hyperplasia and kinetics of worm expulsion that were not different from wild-type mice. RTX-treated mice with confirmed loss of TRPV1+ nerve fibers in the gut and their cell soma in the dorsal root and nodose ganglia, had a greater increase (~2-fold) in tuft cell numbers compared to H. diminuta-only mice at 11 days post-infection.
Conclusions
Knowledge of how the host senses helminths in the gut lumen is central to the host-parasite interaction. Using the H. diminuta-mouse model system we find that tuft cell hyperplasia is largely, but not entirely dependent on adaptive immunity, occurs independent of the gut microbiota, and, intriguingly, TRPV1+ sensory nerves appear to act as a brake on the system, limiting the magnitude of the hyperplasia.

Abstract
Anode passivation is still a main challenge for the electrochemical generation of ferrate(VI, Fe(VI)), leading to the reduction of Fe(VI) production efficiency. In this study, cyclic voltammetry, scanning electronic microscopy, and electrochemical impedance spectroscopy were used to select better anode electrode configurations (iron wire, iron gauze, and iron coil). The results indicate that iron coil had the least degree of passivation. Different imposed current waveforms during the electrochemical generation of Fe(VI) were also investigated, and the iron coil imposed with square alternating current (AC) wave can mitigate the anode passivation, resulting in higher Fe(VI) production efficiency. The optimum conditions for the electrochemical generation of Fe(VI) were evaluated and the optimum temperature (40 ℃), current density (10 mA/cm2), AC cycle period (15 s) and electrolyte concentrations (14 M NaOH) were identified. As a result, 0.12 mol/L Fe(VI) concentration and over 50% of current efficiency can be achieved after 3 h electrolysis. The generated Fe(VI) solution was further applied to oxidize doxycycline(DOX) and sulfadiazine(SDZ) as typical antibiotics. Over 80% of DOX can be removed at a Fe(VI) to DOX molar ratio of 5:1 (pH = 4-9), whilst a higher Fe(VI) to SDZ molar ratio of 20:1 (pH = 7) was needed to obtain 75% SDZ removal.

Abstract
Objective: To evaluate the classification of the types of pediatric posterior fossa brain tumors based on routine MRI (T(1)WI, T(2)WI and ADC) using wavelet transformation analysis of whole tumor. Methods: MRI images of medulloblastoma (n=59), ependymoma (n=13) and pilocytic astrocytoma (n=27) confirmed by pathology before treatments in Children's Hospital of Nanjing Medical University from January 2014 to February 2019 were enrolled in this retrospective study as well as the clinical data of age, gender and symptoms. Registration was performed among the three sequences and wavelet features of ROI were acquired. Afterwards, the top ten features were ranked and trained among groups by using random forest classifier. Finally, the results were compared and analyzed according to the classification. Results: The top ten contribution three sequences and wavelet features of ROI were acquired from the ADC sequence. The random forest classifier achieved 100% accuracy on training data and was validated best accuracy (86.8%) when combined of first and third wavelet features. The sensitivity was 100%, 94.8%, 76.9%, and the specificity was 97.6%, 88.0%, 98.8% respectively. Conclusions: Features based on wavelet transformation of ADC sequence of entire tumor can provide more quantitative information, which could provide help in the differential diagnosis of pediatric posterior fossa brain tumors. The optimum combination to distinguish three pediatric posterior fossa brain tumors is sixth and twelfth wavelet features of ADC sequence.

Abstract
Abstract
Fifteen laboratories completed a collaborative study comparing the efficacy of a latex agglutination kit (Aureus Test) with that of AOAC Official Method 987.09 (coagulase test for identification of Staphylococcus aureus). Each laboratory analyzed 240 strains of bacteria, including 160 isolates of S. aureus and 80 isolates of other bacteria. Upon receipt of cultures, collaborators subcultured each isolate on both tryptic soy agar (TSA) and Baird-Parker agar medium (BPA) to determine whether the growth medium has any effect on either method. For cultures grown on TSA, the latex test had sensitivity and specificity rates of 99.2 and 97.1 %, respectively, whereas the coagulase test had respective rates of 98.4 and 92.5%. For cultures able to grow on BPA, the latex test had sensitivity and specificity rates of 99.2 and 96.6%, respectively, while the coagulase test had respective rates of 98.3 and 91.3%. By using the McNemar pairwise comparison test of the 2 methods, the falsepositive and false-negative rates of the latex test were significantly lower (p < 0.01) than those of the coagulase test for strains grown either on TSA or BPA. The latex agglutination test for identification of S. aureus isolated from foods has been adopted by AOAC INTERNATIONAL.
