A Background-Agnostic Framework with Adversarial Training for Abnormal Event Detection in Video.

IEEE Trans Pattern Anal Mach Intell 2021 Apr 21;PP. Epub 2021 Apr 21.

Abnormal event detection is a complex computer vision problem that has attracted significant attention in recent years. Its complexity arises from the commonly-adopted definition of an abnormal event, that is, a rarely occurring event that typically depends on the surrounding context. We propose a background-agnostic framework that learns from training videos containing only normal events. Read More

Combined Antioxidant-Antibiotic Treatment for Effectively Healing Infected Diabetic Wounds Based on Polymer Vesicles.

ACS Nano 2021 Apr 21. Epub 2021 Apr 21.

Department of Orthopedics, Shanghai Tenth People's Hospital, Tongji University, Shanghai 200072, China.

Infected diabetic wounds are difficult to heal due to high reactive oxygen species (ROS) concentrations and recurrent infections. Such wounds can easily deteriorate into a diabetic ulcer, a chronic diabetic complication with a very high mortality rate. Herein, we propose a combined antioxidant-antibiotic therapy based on poly(ε-caprolactone)--poly(glutamic acid) polymer vesicle to treat infected diabetic wounds. Read More

Clinical significance of vitamin D in idiopathic normal pressure hydrocephalus.

Acta Neurochir (Wien) 2021 Apr 21. Epub 2021 Apr 21.

Department of Neurosurgery, School of Medicine, Kyungpook National University, Daegu, Republic of Korea.

Background: Although recent studies show vitamin D deficiency is associated with cognitive decline, urinary incontinence, and gait instability, there has been no study on the effect of vitamin D on idiopathic normal pressure hydrocephalus (iNPH) characterized by the classic symptom triad of cognitive decline, urinary incontinence, and gait instability. We investigated the clinical significance of vitamin D in patients with iNPH.

Methods: Between 2017 and 2020, 44 patients who underwent ventriculoperitoneal shunt surgery were divided into low (< 15 ng/mL) and high (≥ 15 ng/mL) vitamin D groups according to the concentration of 25(OH)D, an effective indicator of vitamin D status. Read More

Mental time travel in patients "cured" from primary central nervous system lymphoma.

J Clin Exp Neuropsychol 2021 Apr 21:1-12. Epub 2021 Apr 21.

Neuropsychological Therapy Centre (NTC)/Clinical Neuropsychology, Faculty of Psychology, Ruhr University Bochum, Bochum, Germany.

: Significant advances in neuro-oncological treatment led to considering neurocognitive functioning and everyday functional needs in patients with long-term survival. Since a potentially lethal disease interrupts normal life and represents a threat to physical and psychological integrity, patients have to cope with the new challenges. Long-term survival and even "cure" is possible in primary central nervous system lymphoma (PCNSL), however, suffering from a life-threatening disease may affect patients´ cognitive processing of past and future (i.

Hierarchically porous FeNi@FeNi layered double hydroxide nanostructures: one-step fast electrodeposition and highly efficient electrocatalytic performances for overall water splitting.

Dalton Trans 2021 Apr 21. Epub 2021 Apr 21.

College of Chemistry and Materials Science, Key Laboratory of Functional Molecular Solids, Ministry of Education, Anhui Provincial Engineering Laboratory for New-Energy Vehicle Battery Energy-Storage Materials, Anhui Normal University, 189 Jiuhua Southern Road, Wuhu, 241002, PR China.

FeNi-layered double hydroxide (LDH) is thought to be an excellent electrocatalyst for oxygen evolution reaction (OER) but it always shows extremely poor electrocatalytic activity toward hydrogen evolution reaction (HER) in alkaline media. Hence, it is significant to improve its HER activity to make it a bifunctional electrocatalyst for the decomposition of water. Here, a simple galvanostatic electrodeposition method was designed for the successful construction of the bifunctional FeNi3@FeNi LDH electrocatalyst. Read More

Cross-sectional case-control study of the relationships between pharyngeal compliance and heart rate variability indices in childhood obstructive sleep apnoea.

J Sleep Res 2021 Apr 20:e13337. Epub 2021 Apr 20.

Service de Physiologie Pédiatrique-Centre du Sommeil, Université de Paris, AP-HP, Hôpital Robert Debré, INSERM NeuroDiderot, Paris, France.

A combination of noradrenergic and antimuscarinic agents reduces the apnea-hypopnea index (AHI) in adult patients with obstructive sleep apnoea (OSA) via reduced upper airway collapsibility, suggesting that a shift in the sympathovagal balance improves OSA. The objectives of our present case-control study were to assess heart rate variability (HRV) indices in the stages of sleep in children with and without OSA to evaluate OSA-induced sleep HRV modifications and to assess whether increased collapsibility measured during wakefulness is associated with reduced sympathetic activity during non-rapid eye movement (NREM) sleep. Three groups of 15 children were matched by sex, age, z-score of body mass index and ethnicity: non-OSA (obstructive AHI [OAHI] <2 events/hr), mild (OAHI ≥2 to <5 events/hr) or moderate-severe (OAHI ≥5 events/hr) OSA.

Chemical Biology Research Center, School of Pharmaceutical Sciences, Wenzhou Medical University, Wenzhou, 325035, Zhejiang, People's Republic of China.

Cancer is one of the diseases that threatens human health and is a leading cause of mortality worldwide. High levels of reactive oxygen species (ROS) have been observed in cancer tissues compared with normal tissues in vivo, and it is not yet known how this influences chemotherapeutic drug action. Cationic porphyrin 5,10,15,20-tetra-(N-methyl-4-pyridyl) porphyrin (TMPyP4) is a photosensitizer used in photodynamic therapy (PDT) and a telomerase inhibitor used in the treatment of telomerase-positive cancer.

The Role of Biaxial Loading on Smooth Muscle Contractility in the Nulliparous Murine Cervix.

Ann Biomed Eng 2021 Apr 20. Epub 2021 Apr 20.

Department of Biomedical Engineering, Tulane University, 6823 St. Charles Ave, New Orleans, LA, 70118, USA.

Throughout the estrus cycle, the extracellular matrix (ECM) and cervical smooth muscle cells (cSMC) coordinate to accomplish normal physiologic function in the non-pregnant cervix. While previous uniaxial experiments provide fundamental knowledge about cervical contractility and biomechanics, the specimen preparation is disruptive to native organ geometry and does not permit simultaneous assessment of circumferential and axial properties. Thus, a need remains to investigate cervical contractility and passive biomechanics within physiologic multiaxial loading. Read More

Adv Pharm Bull 2021 Feb 5;11(2):286-294. Epub 2020 Aug 5.

School of Pharmacy and Research People's University Bhopal- 462037, MP, India.

The prevalent types of idiopathic inflammatory bowel disease are ulcerative colitis (UC) and Crohn's disease, which affects a large number of populations. Budesonide (BUD) is a glucocorticoid with potent anti-inflammatory activity but low systemic efficacy because of high receptor affinity and rapid diversion. To overcome low efficacy and availability, a novel BUD nano-sponges was formulated using quasi- solvent diffusion and Eudragit S-100 as polymer. Read More
