Alongside reduced participant time burden, remote and virtual data collection allows the participation of individuals who live long distances from hospital or university research centers, or who lack access to transportation. Unfortunately, studies that include magnetic resonance neuroimaging are challenging to perform remotely given the infrastructure requirements of MRI scanners, and, as a result, they often omit socially, economically, and educationally disadvantaged individuals. Lower field strength systems ( less then  100 mT) offer the potential to perform neuroimaging at a participant's home, enabling more accessible and equitable research. Here we report the first use of a low-field MRI "scan van" with an online assessment of paired-associate learning (PAL) to examine associations between brain morphometry and verbal memory performance. In a sample of 67 individuals, 18-93 years of age, imaged at or near their home, we show expected white and gray matter volume trends with age and find significant (p  less then  0.05 FWE) associations between PAL performance and hippocampus, amygdala, caudate, and thalamic volumes. High-quality data were acquired in 93% of individuals, and at-home scanning was preferred by all individuals with prior MRI at a hospital or research setting. Results demonstrate the feasibility of remote neuroimaging and cognitive data collection, with important implications for engaging traditionally under-represented communities in neuroimaging research.Ideally, urgent dermatology referrals for evaluation of a lesion concerning for skin cancer should be triaged and processed with appropriate urgency by primary care and dermatology, respectively. We performed a retrospective single-institution study by conducting chart reviews of all dermatology referrals designated by primary care as urgent for evaluation of a lesion concerning for skin cancer. We identified 320 referrals placed between January 1 and December 31, 2018. Dermatology encounters for these patients occurred on or before 30 days for 50.6% of referrals and on or after 31 days for 38.4% of referrals, with 10.9% never completed. The percentage of all races excluding whites, non-Hispanic in the delayed appointment group (≥ 31 days) was 15.1% higher (95% CI 5.3-24.9) than in the timely appointment group (≤ 30 days). Similarly, the percentage of non-English languages in the delayed group was 7.1% higher (95% CI 0.5-13.7) than in the timely group. Overall, 15.8% of these referrals yielded diagnoses of malignancy, while 76.8% and 7.4% resulted in benign and pre-malignant diagnoses, respectively. The primary care team documented referral status (i.e., completed, incomplete, or pending) during their subsequent visits with the patients in only 37.5% of these referrals. Our findings demonstrate the need to improve the reliability of urgent referrals to ensure they occur in a timely manner with confirmation of "referral loop" closure at the referring clinician's end.The burnout literature is replete with burnout score results from quantitative surveys. There is a paucity of qualitative research that seeks to understand the impact of physician stressors on work-life balance and burnout. This study aimed to identify factors that support and disrupt work-life balance, drivers of burnout, and potential solutions among academic dermatologists. The objective was to better understand factors that promote wellness and ameliorate burnout. Concurrent explanatory mixed methods consisted of scores on the Abbreviated Maslach Burnout Inventory and open-ended semi-structured telephone interviews. The results were that positive factors, such as supportive home life and satisfaction derived from academic endeavors, compete with ongoing feelings of exhaustion, frustration, and apathy. Negative stressors include the electronic medical record, insufficient staffing, administrative and clinical task burden, and perceived lack of interest from mid-level and senior health system leadership in addressing clinicians' needs. This was a single-center academic study. As with all qualitative studies, these results may not be generalizable to all dermatologists. In addition, some participants were concerned about their anonymity. Modifiable root causes of burnout require institutional commitment to sustain the pace required by academic dermatologists.Sirtuin 3 (SIRT3) is reported to be closely relevant to the pathogenesis of psoriasis, but its detailed functions and molecular mechanisms have not been fully studied. Thus, this study aimed to investigate the effects and underlying mechanisms by which SIRT3 regulated the development of psoriasis. Specifically, we verified that SIRT3 was aberrantly downregulated in psoriasis-like skin tissues in mice models in vivo and TNF-α-stimulated HaCaT cells in vitro, compared to their corresponding normal counterparts. Functional experiments confirmed that upregulation of SIRT3 triggered cell mitophagy, restrained oxidative stress and inflammation, and inhibited excessive cell proliferation in the TNF-α-stimulated HaCaT cells in vitro, which were all ablated by co-treating cells with the mitophagy inhibitor 3-MA. Subsequently, the mechanism experiments uncovered that elevated SIRT3 deacetylated forkhead box class o 3A (FOXO3a) for its activation, which further activated the Parkin-dependent cell mitophagy in the HaCaT cells. Next, through performing the rescuing experiments, we validated that SIRT3 ameliorated TNF-α-induced psoriasis-associated phenotypes in the HaCaT cells via modulating the FOXO3a/Parkin signal pathway. Collectively, we concluded that SIRT3 triggered cell mitophagy through activating the FOXO3a/Parkin pathway to ameliorate TNF-α-induced psoriasis in the HaCaT cells, and this study provided evidences to support that SIRT3 could be used as important therapeutic target for the treatment of psoriasis.
This study aimed to evaluate the effects of curcumin by co-administration of arsenic trioxide (As
O
) in acute myeloid leukemia (AML) treatment, using network pharmacology and experimental validation.

Using Pubchem database, Traditional Chinese Medicine Information Database (TCMID) database, and Swiss target prediction database to predict compound-related targets, AML-associated targets were determined using GeneCards and Online Mendelian Inheritance in Man (OMIM) databases. find more We identify overlapping common targets by comparing Compounds-related and AML-associated targets and using these targets to perform GO and KEGG functional enrichment analyses. Subsequently, these targets were input into the STRING database, and we used Cytoscape to construct protein-protein interaction (PPI) network. Finally, we used KG1-a cells and the AML mouse model to measure the anti-leukemia effects of curcumin and As
O
and their combination.

Compounds and targets screening hinted that 85 intersection targets were predictl time of mice in each administration group was drawn out to varying degrees, with the most significant prolongation in the curcumin combined with the As

CD177, an indicator of prognosis in diverse cancers, is involved in the physiological processes of various tumor cells, and acts as an immune molecule with novel functions in cancer pathogenesis. However, the diagnostic, prognostic, and immunological role of CD177 in cervical cancer remains unclear.

Utilizing publicly available databases and integrating several bioinformatics analysis methods, we evaluated the expression level of CD177 in cervical cancer by GENT2, HPA, and GEO databases. And the experiments of western blot and immunohistochemical staining were used to testthehypothesis. The Kaplan-Meier Plotter database, Xena Shiny, and the constructed nomogram were clearly demonstrated its prognostic value for patients. Gene set enrichment analysis explored the relationship between CD177 and cervical cancer immune responses and immune cells infiltration level. In addition, we investigated the association between CD177 expression and stromal score, immune score, immune checkpoint, and drug sensitivity by cervical cancer patients.
Haemorrhoids are common and can significantly impact the personal and working lives of individuals. Those with more severe symptoms and those not responding to conservative management may require surgery. Current surgical techniques are associated with a degree of postoperative discomfort which may delay return to normal activity. Recurrence is lower in more radical procedures but resulting pain is higher. Radiofrequency ablation (RFA) is a new technique that is gaining popularity and has several hypothesised benefits, including reduced pain and recurrence. However, available evidence is limited. A recent overview from the National Institute for Health and Clinical Excellence recommended more research, in the form of randomised controlled trials, be carried out before further investment is made by national health services. Our aim is to assess whether RFA is at least as good in terms of recurrence as existing surgical interventions, but superior in terms of pain, for patients with symptomatic grade II and III haemorrhoids.

The RadiO fRequency ablatION for haemorrhoids (ORION) trial will be a pragmatic multicentre patient/assessor-blind parallel group-controlled trial with economic evaluation. The target sample size is 376 participants (188 per arm) and is based on two co-primary endpoints (i) a non-inferiority design for recurrence and (ii) superiority design for pain at sevendays. Participants with grade II or III haemorrhoids will be recruited in 16 National Health Service hospitals and randomised (11) to either RFA or surgeon's choice of surgery.

Results will inform future practice for the treatment of grade II-III haemorrhoids and provide evidence for national health services on future investments in RFA.

ISRCTN14474552.Lipids play important roles in regulating membrane protein function, but the molecular mechanisms used are elusive. Here we investigated how anionic lipids modulate SthK, a bacterial pacemaker channel homolog, and HCN2, whose activity contributes to pacemaking in the heart and brain. Using SthK allowed the reconstitution of purified channels in controlled lipid compositions for functional and structural assays that are not available for the eukaryotic channels. We identified anionic lipids bound tightly to SthK and their exact binding locations and determined that they potentiate channel activity. Cryo-EM structures in the most potentiating lipids revealed an open state and identified a nonannular lipid bound with its headgroup near an intersubunit salt bridge that clamps the intracellular channel gate shut. Breaking this conserved salt bridge abolished lipid modulation in SthK and eukaryotic HCN2 channels, indicating that anionic membrane lipids facilitate channel opening by destabilizing these interactions.
