High-speed three-dimensional (3D) super-resolution microscopy is a unique tool to investigate various biological phenomena; yet the technology is not broadly adopted due to its high cost and complex system design.

We present a compact, low-cost, and high-speed 3D structured illumination microscopy (SIM) based on a digital micromirror device and binary holography to visualize fast biological events with super-resolution.

The 3D SIM uses a digital micromirror device to generate three laser foci with individually controllable positions, phases, and amplitudes via binary holography at the back aperture of objective lens to form optimal 3D structured patterns. Fifteen raw images are sequentially recorded and processed by the 3D SIM algorithm to reconstruct a super-resolved image.

Super-resolution 3D imaging at a speed of 26.7 frames per second is achieved with a lateral and axial resolution of 155 and 487nm, which corresponds to a 1.65- and 1.63-times resolution enhancement, respectively, comparing with standard deconvolution microscopy.

The 3D SIM realizes fast super-resolution imaging with optimal 3D structured illumination, which may find important applications in biophotonics.

However, identifying the biomarkers for the diagnosis of mTBI is challenging as evident abnormalities in brain anatomy are rarely found in patients with mTBI. In this study, we tested whether the alteration of functional network dynamics could be used as potential biomarkers to better diagnose mTBI. We propose a sparse dictionary learning framework to delineate spontaneous fluctuation of functional connectivity into the subject-specific time-varying evolution of a set of overlapping group-level sparse connectivity components (SCCs) based on the resting-state functional magnetic resonance imaging (fMRI) data from 31 mTBI patients in the early acute phase ( less then 3 days postinjury) and 31 healthy controls (HCs). The identified SCCs were consistently distributed in the cohort of subjects without significant inter-group differences in connectivity patterns. Nevertheless, subject-specific temporal expression of these SCCs could be used to discriminate patients with mTBI from HCs with a classification accuracy of 74.2% (specificity 64.5% and sensitivity 83.9%) using leave-one-out cross-validation. Taken together, our findings indicate neuroimaging biomarkers for mTBI individual diagnosis based on the temporal expression of SCCs underlying time-resolved functional connectivity.

This study aimed to investigate the differences in the relationship between hair cortisol concentration (HCC) and psychosocial stress, social support, clinical features, clinical course, and outcome in schizophrenia and bipolar disorder.

A total of 109 schizophrenia patients, 93 bipolar disorder patients and 86 healthy controls between 18 and 60 years old were enrolled in the study. Linear regression and factor analysis were employed to examine and compare the relationship between HCC and childhood trauma, the number of stressful life events, the amount of social support in the three months before the hair cortisol assessment, clinical fearures, clinical course, and outcome in schizophrenia and bipolar disorder.

HCC is significantly associated with clinical syndromes, including depression-anxiety factor of Positive and Negative Syndrome Scale in schizophrenia patients, and thought disorder in bipolar disorder patients. However, HCC is positively related to social support and personality traits only in schizophrenia patients but not in bipolar disorder patients. Factor analysis indicates schizophrenia and bipolar disorder share a very similar but somewhat different structure in terms of HCC, psychosocial stress, social support, clinical features, clinical course, and outcome.

Findings support that schizophrenia and bipolar disoder have a significant overlap in both clinical characteristics and enviromental risk factors. Aberrant HCC contributes to the complexity of clinical characteristics mainly in schizophrenia.

In the present study, we report evidence that DCAF13 is aberrantly overexpressed in human breast cancer and its expression is positively associated with cancer progression. Further analysis showed that the DCAF13 expression level is significantly higher in triple-negative breast cancer compared to non-triple-negative breast cancer, indicating a positive correlation between its expression and the aggressiveness of breast cancer. Subsequent studies revealed that DCAF13 regulates cancer cell migration, invasion and epithelial-mesenchymal transition in human breast cancer, whereas it has no significant impact on breast cancer cell proliferation, cell cycle progressionor apoptosis. Taken together, our results demonstrate that DCAF13 promotes the epithelial-mesenchymal transition in human breast cancer cells, indicating an involvement in breast cancer metastasis. Furthermore, we report that doxorubicin, a widely used chemotherapy drug, increases DCAF13 expression in breast cancer cells, leading to enhanced cancer cell migration and invasion. These results suggest that doxorubicin chemotherapy may increase the risk of metastasis of drug-resistant breast cancer cells, and future therapeutics targeting DCAF13 may help reduce the risk, especially for patients undergoing chemotherapy.

A key challenge in delivering pragmatic trials of complex interventions is effective implementation within the study period and beyond. We describe a trial of an intervention to improve quality of life in mild dementia (Journeying through Dementia), describe some of the challenges raised in terms of implementation, and illustrate the methods used to ensure effective implementation.

The intervention was delivered by staff within local services and supervised by more experienced clinicians within those services in order to test the intervention in real-world settings and establish the potential for future embedding into practice. Researchers delivered training sessions for all facilitators and supervisors, met at regular intervals with intervention supervisors, and provided feedback on summaries of intervention sessions created by facilitators. We conducted a thematic analysis of the content of meetings and written correspondence between the researchers and intervention supervisors regarding implementation consistent with ethos and content of the intervention manual.

We provide guidance for researchers involved in the trialing of other complex interventions in how these challenges might be overcome. These include recruiting additional staff to deliver the intervention; having clear protocols in place for managing staff absences; using supervision to problem solve participant attendance at intervention sessions and difficult group dynamics; monitoring staff engagement in supervision and addressing problems with engagement with staff and managers when this occurs; giving staff ring-fenced time to deliver the intervention and engage in supervision; and regular monitoring and feedback in relation to the content of the intervention to ensure that it is consistent with ethos and content of the intervention manual.

This study investigated the clinical epidemiological characteristics of nitrous oxide (N

O) abusers in a hospital in China, which have not been systematically reported.

The characteristics of patients abusing N

O who were examined and treated at the Affiliated Hospital of Xuzhou Medical University from January 2017 to December 2020 were analyzed.

A total of 61 patients (average age 21.7 ± 3.2 years; 42 male and 19 female) were enrolled; 60.7% of the patients had an education level of high school or lower, and most (59.0%) had no stable occupation. The mean exposure time was 8.5 ± 7.7 months (range 1-36 months). Only 52.5% of the abusers reported the physician of the relevant exposure history at the first time of visiting the doctor. The main clinical type was mixed (49.2%). The most common clinical manifestation was distal limb numbness (80.3%). click here The most frequent outcome was peripheral neuropathy (59%) and subacute combined degeneration (36%). Serum homocysteine level was elevated in 67.5% (27/40) of the patients, while 44.4% (20/45) showed reduced vitamin B12. Note that 61% (22/36) showed abnormal signals in the posterior or lateral funiculus of the spinal cord, and 97% (31/32) of the patients showed peripheral nerve damage by electromyography. In all cases, symptoms were alleviated after halting N

O intake and receiving nutritional neurotherapy.

N

O abuse can lead to nervous system damage, especially peripheral nerve and spinal cord damage. A full understanding of its clinical epidemiological characteristics is helpful for clinicians to make a timely and clear diagnosis.

The COVID-19 pandemic has created new conditions for medical staff, forcing them to use personal protective equipment (PPE) for an extended duration of time. Headache is a commonly associated side effect of the use of such equipment among healthcare workers.

In this cross-sectional study, 243 frontline healthcare workers at four referral hospitals for COVID-19 were evaluated for the occurrence of headache following the use of PPE and its relationship with blood gas parameters was assessed.

The average age of participants was 36 ± 8 years. Of these, 75% were women. The prevalence of headache after the use of masks was 72.4%, with the N95 mask being the most commonly reported cause of headache (41%). Among patients, 25.1% developed external pressure, 22.2% migraine, and 15.2% tension-type headaches. Headache was more common in the female gender. Apart from gender, only increased heart rate was significantly associated with headache due to mask use (p=.03 and .00, respectively). The mean heart rate was 97.
