The association between NADPH oxidase (NOX) polymorphisms with immunohistochemistry and survival in diffuse large B cell lymphoma patients.

The purpose of this study was to comprehensively analyze the prediction role of NADPH oxidase (NOX)-related polymorphisms (NCF4: rs1883112, CYBA: rs4673, RAC2: rs13058338) and immunohistochemical indices on survival in diffuse large B-cell lymphoma (DLBCL).The impact of NOX polymorphisms were evaluated in 335 DLBCL patients treated with R (rituximab)-CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) from Harbin Medical University Cancer Hospital. We also collected information on their immunohistochemical expression and clinical outcomes.

Anticoagulants for the Control of the Common Vampire Bat (Desmodus rotundus).

Background: In Latin America, there is a high incidence of vampire bat-transmitted rabies in cattle causing increased mortality of livestock, which heavily impacts the agricultural sector. Anticoagulants-based control methods for the common vampire bat (Desmodus rotundus) have been employed continuously since the 1970s with various methods of application, presentations, doses and active ingredients. Studies from half a century ago still serve as a reference for the current use of anticoagulants for bat-borne rabies control in Latin America.

Cold sub-mucosal injection versus traditional cold snare polypectomy for diminutive and small colorectal polyps: A systematic review and meta-analysis.

Background: The guidelines recommend conventional cold snare polypectomy (C-CSP) for diminutive and small colorectal polyps (≤ 10 mm). However, it remains unclear whether CSP with sub-mucosal injection (SI-CSP) achieves comparable efficacy to C-CSP for managing these lesions. This study compares SI-CSP with C-CSP for patients with diminutive and small colorectal polyps.

The Association between NADPH Oxidase 2 (NOX2) and Drug Resistance in Cancer.

NADPH oxidase, as a major source of intracellular reactive oxygen species (ROS), assumes an important role in the immune response and oxidative stress response of the body. NADPH oxidase 2 (NOX2) is the first and most representative member of the NADPH oxidase family, and its effects on the development of tumor cells are gaining more and more attention. Our previous study suggested that NCF4 polymorphism in p40phox, a key subunit of NOX2, affected the outcome of diffuse large B-cell lymphoma patients treated with rituximab.

Metal-Free Heterogeneous Photocatalysis for Carbocarboxylation of Alkenes: Efficient Synthesis of γ-Amino Carboxylic Derivatives.

A metal-free heterogeneous protocol is established herein for the synthesis of value-added γ-amino acid scaffolds via carbocarboxylation of alkenes with CO and alkylamines under visible light irradiation. The protocol shows broad substrate scope under mild reaction conditions and good stability of the catalyst for recycle tests. Moreover, the methodology could be feasible to the late-stage derivatization of several natural products, enriching the chemical arsenal for practical application.

Subnano Te Cluster in Glass for Efficient Full-Spectrum Conversion.

Broadband near-infrared (NIR) photonic materials have wide applications. Although extensive studies on rare-earth, transition-metal, and even semiconductor-activated materials have enabled the development of a rich NIR material pool, developing broadband and efficient photonic candidates covering the NIR I and II regions from 750 to 1500 nm has been met with limited success. Here, it is reported that a subnano Te cluster with a characteristic configuration different from that of the ion state may fill the aforementioned gap.

A Novel Flexible Fixation Method for Syndesmotic Injury.

Background: This study aims to evaluate the results and the safety of a novel fixation method we developed for syndesmosis injuries that we call the "embrace" technique.

Methods: Between March 2018 and October 2020, a total of 67 patients with ankle fractures and syndesmotic injuries underwent syndesmosis fixation with the embrace technique at our institute. Plain radiographs and computed tomographic (CT) scans were obtained preoperatively.

Fifth Metatarsal Base Fracture Combined With Fracture of the Os Peroneum.

Fracture of the os peroneum is rare, and displacement of the fracture can be indicative of a tear in the peroneal longus tendon. A fifth metatarsal base fracture is a common injury caused by sudden inversion and plantar flexion of the hindfoot. We observed a rare case of a fifth metatarsal base zone I fracture combined with a displaced os peroneum fracture in a 34-year-old woman.

A Virtual Combustion Sensor Based on Ion Current for Lean-Burn Natural Gas Engine.

In this study, an innovative sensor was designed to detect the key combustion parameters of the marine natural gas engine. Based on the ion current, any engine structurally modified was avoided and the real-time monitoring for the combustion process was realized. For the general applicability of the proposed sensor, the ion current generated by a high-energy ignition system was acquired in a wide operating range of the engine.

Personal NO sensor demonstrates feasibility of in-home exposure measurements for pediatric asthma research and management.

Background: One of the most common pollutants in residences due to gas appliances, NO has been shown to increase the risk of asthma attacks after small increases in short term exposure. However, standard environmental sampling methods taken at the regional level overlook chronic intermittent exposure due to lack of temporal and spatial granularity. Further, the EPA and WHO do not currently provide exposure recommendations to at-risk populations.

This paper presents a cloud-connected indoor air quality sensor system that can be deployed to patients' homes to study personal microenvironmental exposure for asthma research and management. The system consists of multiple compact sensor units that can measure residential NO, ozone, humidity, and temperature at one-minute resolution and a cloud-based informatic system that acquires, stores, and visualizes the microenvironmental data in real-time. The sensor hardware can measure NO as low as 10 ppb and ozone at 15 ppb.

A Discreet Wearable IoT Sensor for Continuous Transdermal Alcohol Monitoring - Challenges and Opportunities.

Non-invasive continuous alcohol (ethanol) monitoring has potential applications in both population research and in clinical management of acute alcohol intoxication or chronic alcoholism. Current wearable monitors based on transdermal alcohol content (TAC) sensing have limited accessibility and blood alcohol content (BAC) quantification accuracy.

LncRNA IDH1-AS1 suppresses cell proliferation and tumor growth in glioma.

Glioma is a type of brain tumor that is common globally, and is associated with a variety of genetic changes. It has been reported that isocitrate dehydrogenase 1 (IDH1) is overexpressed in glioma and in HeLa cells. The lncRNA IDH1-AS1 is believed to interact with IDH1, and when IDH1-AS1 is overexpressed, HeLa cell proliferation is inhibited.

A narrow-band ultra-bright green phosphor for LED-based applications.

A novel Sr2MgB2O6 (SMBO) green-emitting phosphor co-doped with Ce3+-Tb3+ was synthesized at 950 °C via solid-state reactions, and the ultra-narrow-band green emission of Tb3+ was significantly enhanced almost 20 times via energy transfer from Ce3+ to Tb3+. It was found to have a broad excitation band (250 to 400 nm), and the full width at half-maximum (FWHM) of the dominant green emission band around 544 nm was only about 10 nm. The electronic band gap of the SMBO matrix was calculated by density functional theory (DFT) to be 4.

Multiparametric slice culture platform for the investigation of human cardiac tissue physiology.

Human cardiac slices have emerged as a promising model of the human heart for scientific research and drug testing. Retaining the normal tissue architecture, a multi-cell type environment, and the native extracellular matrix, human cardiac slices faithfully replicate organ-level adult cardiac physiology. Previously, we demonstrated that human cardiac tissue slices cultured for 24 h maintained normal electrophysiology.
