Addition of chemotherapy to intensity-modulated radiotherapy does not improve survival in stage II nasopharyngeal carcinoma patients

Fangzheng Wang, Jiang Chuner, Quanquan Sun et al. · 2018 · Journal of Cancer

In this study, we examined whether combining neoadjuvant chemotherapy (NAC) and/or concurrent chemotherapy (CC) with intensity-modulated radiotherapy (IMRT) improved survival in patients with stage II nasopharyngeal carcinoma (NPC). Two hundred forty-two stage II NPC patients were enrolled between May 2008 and April 2014 and received radical IMRT with simultaneous integrated boost technique using 6 MV photons; some patient groups also received chemotherapy every 3 weeks for 2-3 cycles. The median follow-up duration was 69 months for all patients. At the last follow-up, 18 patients had experien

The ACT-DR5 MCMF galaxy cluster catalog

Matthias Klein, J. J. Mohr, C. T. Davies · 2024 · Astronomy and Astrophysics

Galaxy clusters are useful cosmological probes and interesting astrophysical laboratories. As the cluster samples continue to grow in size, a deeper understanding of the sample characteristics and improved control of systematics becomes more crucial. For this analysis we created a new and larger ACT-DR5-based thermal Sunyaev–Zel’dovich Effect- (tSZE-) selected galaxy cluster catalog with improved control over sample purity and completeness. We employed the red sequence based cluster redshift and confirmation tool MCMF together with optical imaging data from the Legacy Survey DR-10 and infrared

Lactiplantibacillus plantarum 299v supplementation modulates β-cell ER stress and antioxidative defense pathways and prevents type 1 diabetes in gluten-free BioBreeding rats

Pinar Sargin, Mark F. Roethle, Shuang Jia et al. · 2022 · Gut Microbes

The increasing incidence of Type 1 diabetes has coincided with the emergence of the low-fiber, high-gluten Western diet and other environmental factors linked to dysbiosis. Since Lactiplantibacillus plantarum 299 v (Lp299v) supplementation improves gut barrier function and reduces systemic inflammation, we studied its effects in spontaneously diabetic DRlyp/lyp rats provided a normal cereal diet (ND) or a gluten-free hydrolyzed casein diet (HCD). All rats provided ND developed diabetes (62.5±7.7 days); combining ND with Lp299v did not improve survival. Diabetes was delayed by HCD (72.2±9.4 day

Why Is Clozapine Uniquely Effective in Treatment-Resistant Schizophrenia? A Review and Proposal

Robin Murray, Alice Egerton, Yueming Gao et al. · 2025 · Biological Psychiatry

Much is known about the use, benefits, and side-effects, of clozapine in treatment resistant schizophrenia (TRS). However, why clozapine is more effective than other antipsychotics in TRS remains unclear. This paper addresses this question. TRS patients show glutamate abnormalities, and clozapine has widespread effects on glutamate. However, these actions have not been proven different to those of other antipsychotics. Immune dysfunction is also reported in TRS, and clozapine has anti-inflammatory actions, but these have not been correlated with clinical improvement. Currently, there is much i

Effects of Acyclovir and IVIG on Behavioral Outcomes after HSV1 CNS Infection

Chandran Ramakrishna, Mari S. Golub, Abby J. Chiang et al. · 2017 · Behavioural Neurology

Herpes simplex virus 1 (HSV) encephalitis (HSE) has serious neurological complications, involving behavioral and cognitive impairments that cause significant morbidity and a reduced quality of life. We showed that HSE results from dysregulated central nervous system (CNS) inflammatory responses. We hypothesized that CNS inflammation is casually involved in behavioral abnormalities after HSE and that treatment with ACV and pooled human immunoglobulin (IVIG), an immunomodulatory drug, would improve outcomes compared to mice treated with phosphate buffered saline (PBS) or ACV alone.

18F-PI-2620 Tau PET is associated with cognitive and motor impairment in Lewy body disease

Joseph R. Winer, Hillary Vossler, Christina B. Young et al. · 2024 · Brain Communications

Abstract Co-pathology is frequent in Lewy body disease, which includes clinical diagnoses of both Parkinson’s disease and dementia with Lewy bodies. Measuring concomitant pathology in vivo can improve clinical and research diagnoses and prediction of cognitive trajectories. Tau PET imaging may serve a dual role in Lewy body disease by measuring cortical tau aggregation as well as assessing dopaminergic loss attributed to binding to neuromelanin within substantia nigra. We sought to characterize 18F-PI-2620, a next generation PET tracer, in individuals with Lewy body disease. We recruited 141 p

Both species richness and growth forms affect nutrient removal in constructed wetlands: A mesocosm experiment

Yumei Luo, Quan Chen, Fan Liu et al. · 2023 · Frontiers in Ecology and Evolution

Introduction Plant richness is thought to improve the function of constructed wetlands (CWs), but most CWs are planted with monocultures, with only a few employed polycultures, which have drawn contradictory conclusions. We suppose functional diversity is the key to better performance of plant communities and hypothesize that CWs planted with diverse growth forms are superior in plant growth and nutrient removal. Methods In this study, six emergent plant species categorized into slender type ( Schoenoplectus tabernaemontani, Typha orientalis ), fan type ( Iris sibirica, Acorus calamus ) and la

Improving medication adherence in type 2 diabetes: strategies for better clinical and economic outcomes

Patrick Highton, Mark P. Funnell, Pankaj Gupta et al. · 2025 · Diabetologia

Abstract Medication adherence is critical for optimal glycaemic management and the prevention of complications in type 2 diabetes mellitus. Despite its importance, non-adherence remains a prevalent issue, with global estimates suggesting that approximately 38% of people with type 2 diabetes do not take their medications as prescribed, although estimates vary widely due to a range of patient-related, socioeconomic, condition-related (e.g. chronicity, severity of comorbidities) and healthcare system factors. This review synthesises the current evidence on the prevalence of non-adherence in type
