Our goal was to investigate the cases of bilateral aplasia of the anterior cerebral artery (ACA).
The macro- and microdissection of the target human brain arteries of 388 cadaveric cases was applied under the magnifying glass. Each case was photographed and diagrammatically represented in the workbook. The length and the outer diameter of the corresponding arteries on the photos were measured using a computer software program.
There was only one case (1/388 or 0.25%) of bilateral ACA aplasia that belonged to a male adult cadaver. Except for the variations of the posterior communicating artery on one side and the basilar artery, the instance of cerebral pathology was not recorded in this case. We compared the recent case with available literature cases.
Summarizing small number of literature cases, the recent case of bilateral ACA aplasia as the fifth case discovered so far, represents a true morphological rarity.

Several minimally invasive procedures were used to treat displaced intra-articular calcaneal fractures (DIACFs). No agreement among different authors about either the ideal fixation method or which technique is minimally invasive. The aim of this study was to compare functional and radiographic outcomes of two minimally invasive techniques in treatment of Sanders type II and III DIACFs by using K-wires or cannulated screws without bone grafts.
A prospective randomized controlled study was conducted on 28 patients (34 feet) with Sanders type II or III DIACFs, treated by closed reduction and fixation using cannulated screws or K-wires, at the Orthopedics Department of Sohag University Hospital, between April 2020 and February 2022. Functional assessment was done by American Orthopedic Foot and Ankle Society (AOFAS) score and VAS for pain. Radiographic assessment was done by measurement of three calcaneal angles (Gissane, Böhler's, and posterior facet inclination angles) and three calcaneal distances (heightitis than patients in the K-wire group. K-wires had advantages of reduced operative time, and easy removal as an outpatient procedure.
Both techniques avoided wound complications associated with ORIF with the advantage of a shorter hospital stay. Patients in the cannulated screw group had better functional and radiographic outcomes and a lower rate of subtalar arthritis than patients in the K-wire group. K-wires had advantages of reduced operative time, and easy removal as an outpatient procedure.
The management of prosthetic joint infection (PJI) has been widely studied in the context of total hip arthroplasty (THA). However, the outcomes of debridement, antibiotics and implant retention (DAIR) for PJI have never been compared between hip resurfacing arthroplasty (HRA) and THA. This led us to carry out a retrospective case-control study comparing the surgical treatment of post-operative infections between HRA and THA to determine the infection remission rate and the medium-term functional outcomes.
This single-centre case-control study analysed 3056 HRA cases of which 13 patients had a PJI treated by DAIR. These patients were age-matched with 15 infected THA hips treated by DAIR and modular component exchange (controls). Their survival (no recurrence of the infection) was compared and factors that could affect the success of the DAIR were explored sex, body mass index, age at surgery, presence of haematoma, type of bacteria present and antibiotic therapy.
At a mean follow-up of fiveyears (2-7), the infection control rate was significantly higher in the HRA group (100% [13/13]) than in the THA group (67% [10/15]) (p = 0.044). More patients in the THA group had undergone early DAIR (< 30days) (73% [11/15]) than in the HRA group (54% [7/13]). There was no significant difference between the two groups in the ASA score, presence of comorbidities, body mass index and duration of the initial arthroplasty procedure. At the review, the Oxford-12 score of 17/60 (12-28) was better in the HRA group than the score of 25/60 (12-40) in the THA group (p = 0.004).
DAIR, no matter the time frame, is a viable therapeutic option for infection control after HRA.

Acute myeloid leukemia (AML) is an aggressive hematologic malignancy with high mortality, and it is urgent to find new and optimized treatment strategies for AML. In this study, bavachinin, isolated from Psoralea corylifolia L. exhibiting extensive anti-tumor activity in many solid tumors and a series of its synthesized analogs, were screened for their anti-cancer activity on AML cell lines.
The cell viability of AML cells was measured using CCK-8 assays. Cell apoptosis and cell cycle were detected by flow cytometry. The expression of apoptosis-related protein and autophagy-related protein/gene was detected by western blot, immunofluorescence or RT-PCR. Subcutaneous mice tumor model was used to evaluate the anti-cancer activity of D36 in vivo.
D36 robustly induced AML cells death in a dose-dependent manner with the IC
value of 1.0μM for HL-60 cells and 0.81μM for MV4-11 cells at 24h. D36 activated autophagy by inducing the accumulation of LC3B and promoting the autophagy flux. In addition, D36 triggered the extrinsic apoptosis by upregulating the protein level of FAS, cleaved-caspase 8, cleaved-caspase 3 and cleaved-PARP. D36 also blocked the cell cycle at S phase or G
/M phase in AML cells. In addition, we find that activation of caspase cascade induced apoptosis and meanwhile activated autophagy, autophagy activation in turns contributes to apoptosis. Furthermore, D36 suppressed the tumor growth in HL-60 AML-bearing mice without obvious side effects.
This study suggests that D36 is a promising small-molecule for the treatment of acute myeloid leukemia.

We retrospectively investigated 4,996 consecutive patients with known or suspected CAD who underwent rest 201Tl and stress 99mTc-tetrofosmin electrocardiogram (ECG)-gated single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI) and followed up for 3 years to confirm their prognosis. MCE risk over 3 years was estimated using an equation based on that used in the J-ACCESS study. The composite endpoint was the onset of MCEs consisting of cardiac death, non-fatal myocardial infarction (MI), and severe heart failure requiring hospitalization. selleck inhibitor SPBW was calculated by phase analysis with the Heart Risk View-F software and its normal upper limit was set to 38ratification of known or suspected stable CAD patients at low or intermediate risk of MCEs and may help identify higher risk patients who could not be identified as being at risk based on J-ACCESS risk assessment.
To evaluate the feasibility of automatic longitudinal analysis of consecutive biparametric MRI (bpMRI) scans to detect clinically significant (cs) prostate cancer (PCa).
This retrospective study included a multi-center dataset of 1513 patients who underwent bpMRI (T2 + DWI) between 2014 and 2020, of whom 73 patients underwent at least two consecutive bpMRI scans and repeat biopsies. A deep learning PCa detection model was developed to produce a heatmap of all PIRADS ≥ 2 lesions across prior and current studies. The heatmaps for each patient's prior and current examination were used to extract differential volumetric and likelihood features reflecting explainable changes between examinations. A machine learning classifier was trained to predict from these features csPCa (ISUP > 1) at the current examination according to biopsy. A classifier trained on the current study only was developed for comparison. An extended classifier was developed to incorporate clinical parameters (PSA, PSA density, and age). d deep learning and machine learning approach. • The diagnostic accuracy of our csPCa detection AI model improved by including clinical parameters.This study aimed to investigate the frequency of CS and its clinical and functional effects on familial Mediterranean fever (FMF). A hundred FMF patients were included in this study. The presence of CS was investigated by the central sensitization inventory (CSI). In addition to the detailed clinical features of patients and genetic mutations, quality of life, disability, sleep disorders, depression, anxiety, and fibromyalgia frequency were examined to evaluate the negative effects of CS on the individual. Patients were divided into groups according to the presence and severity of CS, and their results were compared. Correlation and multivariate regression analysis were performed to investigate the association of CS with selected demographic and clinical parameters. The mean CSI was 37.72 (SD 19.35), and thirty-eight (38%) patients had CS. Sacroiliitis occurred in 11 patients (11%), amyloidosis in 3 (3%), and erysipelas-like erythema in 11 (11%). The most prevalent genetic mutation was M694/any compound heterogeneous (35.7%), followed by M69V homogeneous (30%). Regarding comparing the patients with and without CS, the number of attacks, disease activity, daily colchicine dose, and all investigated comorbidities were significantly higher in the patients with CS (p less then 0.05). In regression analysis, gender, colchicine dose and sleep disturbance were detected as related parameters with CS (OR (95% CI) 6.05 (1.39; 26.32), p 0.017, OR (95% CI) 6.69 (1.65; 27.18), p 0.008, OR (95% CI) 1.35 (1.35; 1.59), p 0.001, respectively). Concomitant pain sensitization appears to be related to FMF patients' clinical and functional characteristics. These results suggest taking into consideration CS in the management of FMF patients.The goal of this paper is to shed new light on the relation between dream recall and dream experiences by providing a thorough analysis of the process that leads to dream reports. Three crucial steps of this process will be distinguished dream production (the generation of a conscious experience during sleep), dream encoding (storing a trace of this experience in memory) and dream retrieval (accessing the memory trace upon awakening). The first part of the paper will assess how major theories think about the relationship between dream reports and these distinct steps. The second part will systematise how trait and state factors affecting dream recall-given different theoretical assumptions-might interact with dream production, encoding and retrieval. Understanding how the distinct steps of dream recall can be modulated by different factors is crucial for getting a better grip on how to acquire information about these steps empirically and for drawing methodological conclusions with regard to the tools dream research relies on to collect subjective data about dream experiences.
