This comparison emphasizes how T1-weighted intensity and texture-based methods can provide a complementary anatomical structure analysis. While texture-based similarity shows high sensitivity for gray matter differences, T1-weighted intensity shows sensitivity for the detection of white matter differences.Currently, it is still unknown whether human immune deficiency virus (HIV)-related structural alterations in the brain are dependent on age. With people living with HIV at different ages, we aim to investigate age-specific structural alterations in HIV patients. Eighty-three male HIV patients and eighty-three age-matched male controls were enrolled, and high-resolution T1 weighted images were collected and analyzed with four morphological metrics. Then, statistical analyses were respectively conducted to ascertain HIV effects, age effects, and medication effects in brain structure of HIV patients, and the relationship with neuropsychological evaluations were further explored. Finally, discriminative performances of these structural abnormalities were quantitatively testified with three machine learning models. Compared with healthy controls, HIV patients displayed lower gray matter volumes (GMV), lower gyrification index, deeper sulcus depth, and larger cortical thickness (CTH). Age-specific differences were found in GMV and CTH young-aged HIV patients displayed more obvious morphological alterations than middle-aged HIV patients when comparing corresponding age-matched healthy controls. Furthermore, age-specific long-term medication effect of combination antiretroviral therapy were also presented. Additionally, several subcortical structural changes were negatively associated with language, attention and motor functions. Finally, three machine learning models demonstrated young-aged HIV patients were easier to be recognized than middle-aged HIV patients. Entinostat Our study indicated young-aged HIV patients were more vulnerable to HIV infection in brain structure than middle-aged patients, and future studies should not ignore the age effect in studying the HIV-related abnormalities.
ZFP91, an E3 ligase, has been reported to possess cancer-promoting functions. This study aimed to elucidate the exact role of ZFP91 in tumour progression of pancreatic cancer and underlying mechanisms.

We analysed the correlation between ZFP91 expression and pancreatic cancer through TCGA and GEO data sets. Growth curve, colony formation, wound healing and transwell invasion assays were conducted to evaluate proliferation, migration and invasion of lentivirus transfected pancreatic cancer cells. GSEA and Western blot analysis were performed to validate the regulatory effect of ZFP91 on β-catenin. Drug response curve and orthotopic implantation model reflected the sensitivity of chemotherapies.

ZFP91 overexpression is prevalent in pancreatic cancer and negatively correlated with overall survival. ZFP91 knock-down attenuated proliferation, migration and invasion of pancreatic cancer cells. β-catenin was a downstream gene of ZFP91, and its agonist could reverse the phenotype. ZFP91 promoted EMT and chemoresistance in pancreatic cancer.

We demonstrated that ZFP91 promoted pancreatic cancer proliferation, migration and invasion through activating β-catenin signalling. EMT and chemoresistance were also regulated by ZFP91. ZFP91 might be a potential therapeutic target for pancreatic cancer.

Approximately 6 days after starting intravenous administration of amiodarone (600 mg/day) for maintaining sinus rhythm after cardioversion of AF, electrocardiograms revealed a prolonged QT interval associated with torsade de pointes (TdP). The amiodarone-induced TdP disappeared after intravenous administration of landiolol plus magnesium and potassium, without discontinuation of amiodarone or overdrive cardiac pacing, although the prolonged QT interval persisted. To the best of our knowledge, this is the first report that landiolol could be effective for amiodarone-induced TdP.
Quinolones are globally popular antibiotics with proven potency, broad coverage, and reasonable safety. However, some concerns were raised as to their possible association with acute liver failure (ALF). The aim of this study is to assess ALF risk within 30days of receiving a systemically administered quinolone antibiotic, in individuals with no history of liver/diseases.

We conducted a nested case-control study using electronic health records from the Cerner Health Facts. The initial cohort (n=35349943) included all patients who were admitted between 2000 and 2016, with no history of liver diseases, and had a minimum medical history of one year. Eligible cases were inpatients who were first diagnosed with ALF between 2010 and 2015. Using incidence density sampling, each case was matched with up to five unique controls by sex, race, age at index encounter, and period-at-risk. We used conditional logistic regression to calculate the odds ratio and 95% confidence interval for ALF risk, upon adjusting for exposure to other medications, and major confounders (diabetes mellitus and alcohol abuse). We used the STROBE Statement for reporting on our study.

We identified 3151 cases and 15657 controls. Our primary analysis did not reveal an association between quinolones and ALF risk. However, some risk was identified among those with no or few comorbidities, those ≤60years of age, women, men, African Americans, and Caucasians.

Although our study does not suggest an overall association between quinolones and ALF, elevated risks seen in some subgroups warrant further investigation.

Fear-learning through observing others begins early in life. Yet, most observational fear-learning research has focused on adults. The current study used a novel developmentally appropriate observational fear conditioning paradigm to examine differences in observational fear-learning among children, adolescents, and adults.

Thirty-six typically developing children, 41 typically developing adolescents, and 40 adults underwent differential observational fear conditioning followed by a direct exposure test. Skin conductance response (SCR) and self-reported fear were measured.

Successful differential observational fear-learning was demonstrated in all three age groups as indexed by SCR, yet developmental differences emerged. Children showed overall higher physiological arousal during acquisition compared to adolescents and adults. Additionally, children reported less differential fear and were less successful at reporting the conditioned stimulus-unconditioned stimuluscontingency compared to adolescents and adults. Finally, adolescents tended to overgeneralize their fear compared with adults.

This is the first study to compare observational fear-learning among children, adolescents, and adults. The novel task effectively induced observational fear-learning, particularly among adolescents and adults. Findings revealed developmental differences that have both theoretical and clinical implications.

Frailty is a geriatric syndrome with negative health impacts not captured by comorbidity and disability alone. The prevalence of frailty in Parkinson's disease (PD) has been described, but data on frailty-associated outcomes are limited.

To describe the level of frailty and investigate the association between frailty and outcomes in a Medicare sample of persons diagnosed with PD.

We used the claims-based frailty index to assess frailty in a cohort of Medicare beneficiaries with PD in 2013. Frailty was categorized as non-frail/pre-frail, mildly frail, moderately frail, and severely frail. Adjusted logistic regression models examined the relationship between frailty and mortality, hospitalization, emergency department visits, and fall-related injuries through 2014.

Of 62,786 beneficiaries with PD in 2013, 55.3% were frail. Frail individuals were more likely to be female, older, Black, metropolitan dwelling, without neurologist care, nursing facility residents, or multimorbid. The average daily levodopa -based frailty surveillance may identify vulnerable PD patients in health system, registry, or administrative data. © 2021 International Parkinson and Movement Disorder Society.Complexes of RhI and IrI of the [M(COD)(NHC)X] type (where M=Rh or Ir, COD=1,5-cyclooctadiene, NHC=N-heterocyclic carbene, and X=halide) have recently shown promising cytotoxic activities against several cancer cell lines. Initial mechanism of action studies provided some knowledge about their interaction with DNA and proteins. However, information about their cellular localization remains scarce owing to luminescence quenching within this complex type. Herein, the synthesis of two rare examples of luminescent RhI and IrI [M(COD)(NHC)I] complexes with 1,8-naphthalimide-based emitting ligands is reported. All new complexes are comprehensively characterized, including with single-crystal X-ray structures. Steric crowding in one derivative leads to two distinct rotamers in solution, which apparently can be distinguished both by pronounced NMR shifts and by their respective spectral and temporal emission signatures. When the photophysical properties of these new complexes are exploited for cellular imaging in HT-29 and PT-45 cancer cell lines, it is demonstrated that the complexes accumulate predominantly in the endoplasmic reticulum, which is an entirely new finding and provides the first insight into the cellular localization of such IrI (NHC) complexes.
Hyposmia is characteristic of idiopathic Parkinson's disease (PD) and dementia with Lewy bodies (DLBs), whereas progressive supranuclear palsy (PSP) typically has normal sense of smell. However, there is a lack of pathologically confirmed data.

The objective is to study hyposmia in pathologically confirmed PSP patients and compare to PD patients and nondegenerative controls.

We studied autopsied subjects in the Arizona Study of Aging and Neurodegenerative Disorders who had antemortem olfactory testing and a neuropathological diagnosis of either PD, PSP, or control.

This study included 281 cases. Those with neuropathologically confirmed PSP (N = 24) and controls (N = 174) had significantly better sense of smell than those with PD (N = 76). Although most PSP patients had normal olfaction, there were some with hyposmia, resulting in an overall reduced sense of smell in PSP compared to controls. The sensitivity of having PSP pathologically in those presenting with parkinsonism and normosmia was 93.4% with a specificity of 64.
