All-Inorganic Perovskite Quantum-Dot Optical Neuromorphic Synapses for Near-Sensor Colored Image Recognition.

As the demand for the neuromorphic vision system in image recognition experiences rapid growth, it is imperative to develop advanced architectures capable of processing perceived data proximal to sensory terminals. This approach aims to reduce data movement between sensory and computing units, minimizing the need for data transfer and conversion at the sensor-processor interface. Here, an optical neuromorphic synaptic (ONS) device is demonstrated by homogeneously integrating optical-sensing and synaptic functionalities into a unified material platform, constructed exclusively by all-inorganic perovskite CsPbBr quantum dots (QDs).

Phase II Trial of Nivolumab Plus Doxorubicin, Vinblastine, Dacarbazine as Frontline Therapy in Older Adults With Hodgkin Lymphoma.

Purpose: We conducted a phase I/II study evaluating nivolumab plus doxorubicin, vinblastine, dacarbazine (N-AVD) as frontline therapy for treatment-naïve older adults (OA) with classical Hodgkin lymphoma (cHL; ClinicalTrials.gov identifier: NCT03033914).

Methods: Patients age ≥60 years with newly diagnosed, any stage, cHL were treated with six cycles of AVD at standard doses plus nivolumab 240 mg intravenously once every 2 weeks (on days 1 and 15) of each cycle.

Ustilago maydis Trf2 ensures genome stability by antagonizing Blm-mediated telomere recombination: Fine-tuning DNA repair factor activity at telomeres through opposing regulations.

TRF2 is an essential and conserved double-strand telomere binding protein that stabilizes chromosome ends by suppressing DNA damage response and aberrant DNA repair. Herein we investigated the mechanisms and functions of the Trf2 ortholog in the basidiomycete fungus Ustilago maydis, which manifests strong resemblances to metazoans with regards to the telomere and DNA repair machinery. We showed that UmTrf2 binds to Blm in vitro and inhibits Blm-mediated unwinding of telomeric DNA substrates.

PM induces lung inflammation through ANGPTL4.

Fine particulate matter (PM) is a common major air pollutant associated with decreased lung function, induced allergic airway inflammation closely correlated with chronic lung diseases. Angiopoietin-like protein 4 (ANGPTL4) is a cytokine with multiple functions, participating in processes such as inflammation, angiogenesis, and metastasis. Curcumin is an active compound found in turmeric plants and possesses various pharmacological effects, including antioxidant, anti-inflammatory, anticancer, and immunomodulatory properties.

Zanubrutinib, Obinutuzumab, and Venetoclax for First-Line Treatment of Mantle Cell Lymphoma with a TP53 Mutation.

TP53-mutant mantle cell lymphoma (MCL) is associated with poor survival outcomes with standard chemoimmunotherapy. Dual BTK and BCL2-inhibition with or without anti-CD20 monoclonal antibody therapy has shown promising activity in TP53-mutant MCL. We conducted a multi-center phase 2 study of zanubrutinib, obinutuzumab, and venetoclax (BOVen) in untreated MCL patients with TP53 mutation.

165 MHz highly stable femtosecond Er:ZBLAN fiber laser operating at 2.8 µm.

Three-micrometer mid-infrared (MIR) femtosecond pulse sources with a high repetition rate (HRR) have potential applications in a number of fields such as biological imaging, optical frequency combs, and gas detection. In this paper, by optimizing the fiber length and the cavity structure, we demonstrated a highly stable, self-starting mode-locked fluoride fiber laser (MLFFL) with a fundamental repetition rate of ∼165 MHz and a signal-to-noise ratio (SNR) of 90 dB. As far as we know, this stands as the highest fundamental repetition rate ever acquired directly from an ultrafast MLFFL in the >2.

Nervonic acid protects against oligodendrocytes injury following chronic cerebral hypoperfusion in mice.

Chronic cerebral hypoperfusion (CCH) has been acknowledged as a potential contributor to cognitive dysfunction and brain injury, causing progressive demyelination of white matter, oligodendrocytes apoptosis and microglia activation. Nervonic acid (NA), a naturally occurring fatty acid with various pharmacological effects, has been found to alleviate neurodegeneration. Nonetheless, evidence is still lacking on whether NA can protect against neurological dysfunction resulting from CCH.

The Princeton IV Consensus Recommendations for the Management of Erectile Dysfunction and Cardiovascular Disease.

The Princeton Consensus (Expert Panel) Conference is a multispecialty collaborative symposium dedicated to optimizing sexual function and preserving cardiovascular health. The Fourth Princeton Consensus Conference was convened on March 10-11, 2023, at the Huntington Medical Research Institutes in Pasadena, California. Princeton panels I to III addressed the clinical management of men with erectile dysfunction (ED) who also had cardiovascular disease.

In Vitro Generation of Haploid Germ Cells from Human XY and XXY Immature Testes in a 3D Organoid System.

Increasing survival rates of children following cancer treatment have resulted in a significant population of adult survivors with the common side effect of infertility. Additionally, the availability of genetic testing has identified Klinefelter syndrome (classic 47,XXY) as the cause of future male infertility for a significant number of prepubertal patients. This study explores new spermatogonia stem cell (SSC)-based fertility therapies to meet the needs of these patients.

Medical students' preferences for asynchronous online or face-to-face learning strategies in learning gross anatomy and neuroanatomy during the COVID-19 pandemic.

Gross anatomy and neuroanatomy are fundamental subjects in medical education. However, learning different anatomical terms and understanding the complexity of the subjects are often challenging for medical students. At National Taiwan University, the 2020-2021 cohort adopted a face-to-face (F2F) learning strategy for gross anatomy and neuroanatomy lecture and laboratory courses until May 17, 2021.

Regulating Tissue Growth Factors for Healing With Etherified Carboxymethylcellulose Matrix.

Etherified Carboxymethylcellulose Matrix (eCMC) is a revolutionary application of carboxymethylcellulose (CMC) in wound care, known for its potential in hemostasis and tissue regeneration. This study aims to investigate the mechanism of eCMC in tissue healing by establishing a rat burn model and administering eCMC as a treatment. The objective is to analyze cytokines and inflammatory mediators using a Cytokine Array and histochemical staining to understand the effects of eCMC on tissue regeneration.

Proceedings of PRINCETON IV: PDE5 inhibitors and cardiac health symposium.

Introduction: Prior consensus meetings have addressed the relationship between phosphodiesterase type 5 (PDE5) inhibition and cardiac health. Given significant accumulation of new data in the past decade, a fourth consensus conference on this topic was convened in Pasadena, California, on March 10 and 11, 2023.

Objectives: Our meeting aimed to update existing knowledge, assess current guidelines, and make recommendations for future research and practice in this area.

Feminist perspectives on environmental justice and health in Jamaica.

Jamaica is an island nation with a history that is informed by Taino settlement, European colonisation, chattel slavery, disinvestment, and continued extractivism. This perspective paper leverages a historical analysis to explore environmental injustices affecting the health and quality of life of Jamaicans living in Jamaica. This article hopes to contribute to a growing but limited body of scholarly research that contends with environmental and climate justice in the context of the Caribbean.

Suppression of Lattice Doubling in Quasi-Skutterudite LaRhSn: A Comparison of Temperature and Hydrostatic Pressure Routes.

We present structural properties at different temperatures and high-pressure (HP) of LaRhSn which is one of the interesting systems in the Remika phase RERhSn (RE=Sr, Ca, La, Pr, Ce) quasi-skutterudite series using synchrotron diffraction. Data at ambient conditions revealed the presence of several weak reflections, which could be accounted only with a superlattice I* structure (I432) with lattice parameter a~19.457 Å.

The autophagic regulation of rosiglitazone-promoted adipocyte browning.

Browning of white adipocytes is considered an efficient approach to combat obesity. Rosiglitazone induces the thermogenetic program of white adipocytes, but the underlying mechanisms remain elusive. Expression levels of browning and autophagy flux markers were detected by real-time PCR and immunoblotting.
