Abstract
Background
Gallbladder cancer (GC) is a uncommon and highly malignant tumor. This study compared the effects of simple cholecystectomy (SC) and extended cholecystectomy (EC) on the long-term survival of stage I GC.
Methods
Patients with stage I GC between 2004 and 2015 in the SEER database were selected. Meanwhile, this study collected the clinical information of patients with stage I GC admitted to five medical centers in China between 2012 and 2022. Using clinical data from patients in the SEER database as a training set to construct a nomogram, which was validated in Chinese multicenter patients. Long-term survival between SC and EC were distinguished using propensity score matching.
Results
A total of 956 patients from the SEER database and 54 patients from five Chinese hospitals were included in this study. The independent prognostic factors were age, sex, histology, tumor size, T stage, grade, chemotherapy and surgical approach by multivariate Cox regression analysis. We developed a nomogram based on these variables. The nomogram has been proved to have good accuracy and discrimination in internal and external validation. The cancer-specific survival (CSS) and overall survival of patients receiving EC were better than those of SC before and after the propensity score match. The interaction test showed that EC was associated with better survival in patients aged ≥ 67 years (P = 0.015) and in patients with T1b and T1NOS (P < 0.001).
Conclusion
A novel nomogram to predict CSS in patients with stage I GC after SC or EC. Compared with SC, EC for stage I GC had higher OS and CSS, especially in specific subgroups (T1b, T1NOS, and age ≥ 67 years).

Abstract
Purpose As the lenticulostriate arteries (LSAs) perfuse neurologically important areas, it is necessary to accurately assess the origin and number of the LSAs before surgery. Although three-dimensional time-of-flight angiography (3D-TOF MRA) is a non-invasive procedure, it requires high-resolution (HR) images to depict LSAs with a small diameter. Therefore, we performed 3D-TOF MRA with the maximum HR using 3T-MRI (HR-MRA) to examine whether a good depiction of the LSAs, equivalent to that of digital subtraction angiography (DSA), could be obtained.
Methods Our study group comprised 16 consecutive patients who underwent HR-MRA and 3D-DSA. In both studies, we evaluated the following issues that include the localization of the origin from M1, M2, and A1 segments, their number of stems, and depiction.
Results There was no significant difference in the visualization of the LSAs between HR-MRA and 3D-DSA (P-values; M1, M2, and A1=0.39, 0.69, and 0.69, respectively), and both the number of stems and the localization of the origin of the LSAs were the same between them.
Conclusion Good depiction of the LSAs can be obtained using HR-MRA with 3T-MRI, and the number of stems and the location of the origin of LSAs can be evaluated almost identically to that obtained by 3D-DSA.

Abstract

Introduction
According to the ABC model of positive feelings, responding to positive activating events with irrational beliefs will result in dysfunctional positive feelings. Positive emotional disturbance is an important marker of bipolar spectrum disorders. Evidencing the role of irrational beliefs in dysfunctional positive feelings may have important clinical implications. However, no study has tested this model. Here, we tested the ABC model of positive feelings based on the REBT model of emotion.
Method
115 participants had to imagine eight unexpected anticipatory positive situations. Then they reported how vividly they imagined the situations, and what they would believe and feel if they were in each situation. After that, they completed a hypomania scale, a general measure of positive irrational beliefs, and a general measure of irrational beliefs about adverse events.
Results
Results showed that situational positive primary irrational beliefs mediate the effect of vividness of imagining positive situations on dysfunctional positive feelings (b = 2.436, 95% CI: LL = 1.314 to UL = 3.832) while situational preferences mediated the effect of positive events on functional positive feelings (b = 0.642, 95% CI: LL = 0.165 to UL = 1.209). Moreover, the effect of positive primary irrational beliefs on dysfunctional positive feelings was mediated by secondary positive irrational beliefs such as positive intolerance (b = 3.826, 95% CI: LL = 0. 370; to UL = 7.740), and extreme self-valuing (b = 1. 330, 95% CI: LL = 0.287 to UL = 2.471) but not by wonderfulizing (b = 0.061, 95% CI: LL= -3.337 to UL = 3.298).
Conclusions
Evidencing an ABC model of positive feelings and showing the role of irrational beliefs in dysfunctional and functional positive feelings may advance existing treatments for promoting mental health and reducing the disturbances of positive emotions.

Background: Accelerated orthodontics has revolutionized the field of orthodontic treatment. Reducing the overall treatment time remains the prime concern of an orthodontist. A good accelerating technique should be affordable, repeatable, practical, efficient and should not have any side effects on periodontium including root and alveolar bone. In the era of technology, many advances are made and newer techniques for accelerating orthodontic tooth movement have been introduced in order to reduce the length of treatment with minimal risk of side effects. This study was conducted to compare the biochemical changes in rapid and conventional orthodontic tooth movement.
Materials and Method:A split mouth study was conducted on thirty patients undergoing fixed orthodontic treatment requiring all four first premolar extraction. The extraction space closure, was carried out with micro osteoperforations on the distal aspect of both the maxillary canines along with orthodontic force application as experimental site on the right side and conventional orthodontic tooth movement as control site on the left side. GCF was collected before the micro osteoperforation (T0), at day 3 (T1), at day 7 (T2) and at 4 weeks (T3) of initiating canine retraction from the distal gingival crevice of both the maxillary canines. Quantitative analysis of IL-1 and Osteocalcin in GCF sample was assessed using enzyme linked immune sorbent assay. The optical density of samples was calculated using a fully automated enzyme linked immunosorbent assay reader.
Result: The level of Interleukin-1and Osteocalcin was always higher at the micro osteoperforation site compared to that of baseline values.
Conclusion:A gradual increase in the levels of IL-1 and Osteocalcin was observed in both the conventional and micro osteoperforation site but statistically significant elevated levels of IL-1 and Osteocalcin were seen in micro osteoperforation site compared to conventional site.

Abstract-

Aim: The present study aimed to compare and evaluate debris and irrigant extrusion from curved root canals using different Ni-Ti systems.

Materials and Method: 30 single rooted mandibular premolars were used in this study. Crown was decoronated, working length and initial apical diameter was established. 1.5% agar gel model was used in this study. Samples were assigned randomly into 3 groups (n = 10 teeth per group). Protaper Next, OneShape, NT GOLD files were used according to the manufacturers’ instructions for canal instrumentation. Apically extruded debris and irrigant was computed by deducting the initial weight of the test apparatus without a tooth from its weight after the biomechanical preparation. Comparative analysis of the amount of apically extruded debris and irrigant for each of the instruments and the experimental models was performed.
Results: Statistically significant difference was found between the three experimental groups. (P <.05). Amid all the groups least extrusion was observed in the Protaper Next group when used in combination with conventional irrigation
Conclusion: All the instruments produced apically extruded debris and irrigant, but maximum was seen with OneShape among the experimental groups.

Magnets have been used widely in the field of dentistry for many years with some success, as they can be manufactured in small dimensions as a retentive devices in overdenture technique, maxillofacial prosthesis and obturators. These magnet attachment attached to osseointegrated implants which transfer the occlusal load to the bone, thereby prevent resorption of remaining alveolar bone and improves the retention and stability of the denture. Magnetic assembly consist of magnet and ferromagnetic metal keeper. More recently, magnets have been made from alloys of the rare earth elements samarium and neodymium, which provides stronger magnetic force per unit size. Magnets are sealed by means of the latest laser lasing techniques thus protect magnet from corrosion in oral cavity. The present article demonstrates the rehabilitation of completely edentulous patient with the help of implant supported mandibular overdenture with magnet attachment and conventional maxillary denture.

Abstract
Background: Cone beam computer tomography (CBCT) when imaged for maxillary jaw generally depicts maxillary sinus. This region is frequently neglected by dentist and maxillofacial radiologist. Signs and symptoms in odontogenic diseases of the jaw and the maxillary sinus may overlap each other. A dental surgeon primarily encounters these lesions in routine dental radiographs..
Aim: The present study was undetaken to evaluate the occurrence of maxillary sinus anomalies in CBCT images of asymptomatic patients and to determine their prevalence, type and location.
Materials and methods: Study consisted of 256 CBCT images of the patients depicting maxillary sinus who has been advised limited volume CBCT as part of routine dental investigation for implant planning, orthodontic assessment, oral surgical procedure, oral pathology etc.. The CBCT images were scrutinized for various maxillary sinus pathologies like mucosal thickening, opacification, polyp and retention pseudocyst
Result: Out of 236 subjects, 106 (44.9%) presented with maxillary sinus abnormalities. The maxillary sinus abnormalities which were found in the study were as follows, mucosal thickening 60 (25.4%), opacification 32 (13.6%), sinus polyp 8 (3.4%) and retention pseudocyst 6 (2.5%). Right maxillary sinus were involved in 58 (24.6%) cases and left in 44 (18.6%) cases respectively, whereas bilateral sinus involvement was seen in 4 (1.7%) cases.
Conclusion: The results are suggestive of high incidence of abnormalities in asymptomatic maxillary sinus. Thus a prompt recognition of these abnormalities by dental surgeons and referral to specialist may help in treating these diseases at an early stage.

One-Trial Appetitive Learning Tasks for Drug Targeting
Authors: Lalonde Robert , Strazielle Catherine 
Published: June 2023

Abstract:
One-trial appetitive learning developed from one-trial passive avoidance learning as a
standard test of retrograde amnesia. It consists of one learning trial followed by a retention test, in
which physiological manipulations are presented. As in passive avoidance learning, food- or waterdeprived
rats or mice finding food or water inside an enclosure are vulnerable to the retrograde amnesia
produced by electroconvulsive shock treatment or the injection of various drugs. In one-trial taste
or odor learning conducted in rats, birds, snails, bees, and fruit flies, there is an association between a
food item or odorant and contextual stimuli or the unconditioned stimulus of Pavlovian conditioning.
The odor-related task in bees was sensitive to protein synthesis inhibition as well as cholinergic receptor
blockade, both analogous to results found on the passive avoidance response in rodents, while the
task in fruit flies was sensitive to genetic modifications and aging, as seen in the passive avoidance response
of genetically modified and aged rodents. These results provide converging evidence of interspecies
similarities underlying the neurochemical basis of learning.

Published: June 2023

This study aimed to calculate the design earthquake with a harmonic sine wave approach at a frequency of 1.5 Hz; 2.5 Hz; 3.5 Hz; 4;5 Hz, as well as Loma Prieta, Northridge, and Kobe ground motion. In addition, a structural response review was also carried out based on a comparison of the effects of the ground motion and sine wave earthquake forces. This study used an experimental method of modelling an apartment building with a scale of 1: 50. The case study was located in Mantrijeron, Yogyakarta, which has a seismic category in the medium-size class. The analysis phase began with material definition, element dimension estimation, modelling by analysis software, loading estimation, structural analysis, and comparison of structural responses based on the deviation. The results indicate that the building model could withstand dynamic loads from harmonic waves up to a frequency of 5.5 Hz for one minute of vibration. The most significant deviation is shown at a frequency of 4.5 Hz with an x-axis direction of 0.110 and a y-direction of 0.160. The structural response resulting from ground motion loading shows that the highest deviation occurred due to the influence of the Kobe earthquake, with a deviation of 0.063 in the x-axis direction and 0.054 in the y-axis direction. Based on these results, the effect of harmonic sine waves is greater than the ground motion loading on the response of the building structure, so it is used as an experimental loading through a vibrating table with the actual residual deviation results showing a value of 0.9 mm in the y-axis direction. The difference in structural response results could be caused by the supports and connections modelling in planning through analysis software which could not precisely represent the actual implementation of the building model.

Structure of Koszul Algebra in Lie Algebra M_(3,1) (R)⋊〖gl〗_3 (R)AbstractIn this research, we study the affine Lie algebra aff(3) of 12 dimension which is the semi-direct sum of the vector space of a matrix of 3x1 and Lie algebra of a matrix of 3x3. The research aims to prove the existence and structure of koszul algebras on the affine Lie algebra aff(3) . Since its Lie algebra is Frobenius then there exists a linear functional whose values in the matrix structure are not equal to zero. Such a linear functional is called a Frobenius functional. Furthermore, in this study, it is also given how to obtain the structure matrix, to calculate its determinants, and to choose the right Frobenius functional. The results obtained in this study are explicit formulas for the structure of the koszul algebra on 12-dimensional Lie affine algebra through induction in the symplectic form of its Frobenius functional. As a discussion material for further research, the results obtained can be developed to determine the structure of koszul algebra in affine Lie algebra of dimension n(n+1).
