The value of thoracoscopic ultrasound for the localization of ground-glass opacities with incomplete lung collapse in video-assisted thoracoscopic surgery.

Background: Video-assisted thoracoscopic surgery (VATS) has been widely used for the resection of lung lesions. However, it is difficult to palpate or see small lesions, especially ground-glass opacities (GGOs) during VATS. Thoracoscopic ultrasound has definite value in locating pulmonary parenchymal nodules.

Background: The diagnosis and treatment of attention deficit hyperactivity disorder (ADHD) comorbid with epilepsy have been insufficiently addressed in China. We conducted a study in China to investigate the current status, diagnosis, and treatment of ADHD in children to further our understanding of ADHD comorbid with epilepsy, strengthen its management, and improve patients' quality of life.

Methods: We carried out a multicenter cross-sectional survey of children with epilepsy across China between March 2022 and August 2022.

Obesity Paradox in Patients with Acute Coronary Syndrome: Is Malnutrition the Answer?

Background: Obesity paradox has been reported in patients with cardiovascular disease, showing an inverse association between obesity as defined by BMI (in kg/m) and prognosis. Nutritional status is associated with systemic inflammatory response and affects cardiovascular disease outcomes.

Objectives: This study sought to examine the influence of obesity and malnutrition on the prognosis of patients with acute coronary syndrome (ACS).

Clinical characteristics and prognosis of patients with hypertrophic cardiomyopathy and heart failure with preserved ejection fraction.

Background: Whether heart failure with preserved ejection fraction (HFpEF) is associated with an increased risk of developing systolic dysfunction and a poor prognosis in hypertrophic cardiomyopathy (HCM) patients is unknown.

Objective: We aimed to assess risk factors for the development of end-stage (ES) heart failure (HF) (ejection fraction < 50%) and compare the prognosis of different HF phenotypes.

Methods: This retrospective study was conducted on patients with HCM in China between January 2009 and February 2023.

Using Contactless Facial Image Recognition Technology to Detect Blood Oxygen Saturation.

Since the outbreak of COVID-19, as of January 2023, there have been over 670 million cases and more than 6.8 million deaths worldwide. Infections can cause inflammation in the lungs and decrease blood oxygen levels, which can lead to breathing difficulties and endanger life.

Adsorption and desorption characteristics of heavy metals onto conventional and biodegradable plastics.

Biodegradable plastics have been widely used to replace conventional plastics to minimize environmental impacts of plastic packaging. However, before biodegradable plastics decompose in the environment, they could pose a threat to terrestrial and aquatic creatures by acting as vectors of contaminants in the food chain. In this study, conventional plastic bags (CPBs) made of polyethylene and biodegradable plastic bags (BPBs) made of polylactic acid were examined for their heavy metal adsorption.

Discovery, evaluation and mechanism study of WDR5-targeted small molecular inhibitors for neuroblastoma.

Neuroblastoma is the most common and deadliest tumor in infancy. WDR5 (WD Repeat Domain 5), a critical factor supporting an N-myc transcriptional complex via its WBM site and interacting with chromosome via its WIN site, promotes the progression of neuroblastoma, thus making it a potential anti-neuroblastoma drug target. So far, a few WIN site inhibitors have been reported, and the WBM site disruptors are rare to see.

Effect of light irradiation on heavy metal adsorption onto microplastics.

Microplastics are frequently found in many environmental media. Polypropylene (PP) is one of the plastics commonly used, resulting in more and more PP fragments in natural waters. Contaminants, such as lead (Pb), could get adsorbed onto microplastics after the exposure to sunlight, and pose a larger threat to aquatic species.

[Difference of musculoskeletal ultrasound imaging of focus of knee joint tendon between patients with knee osteoarthritis and healthy subjects].

Objective: To observe the imaging features of focus of knee joint tendon in patients with knee osteoarthritis (KOA) by musculoskeletal ultrasound (MSUS) technique.

Methods: One hundred KOA patients and 100 healthy subjects were included. All the KOA patients were palpated by the sequence of foot meridian, foot meridian, foot meridian and foot three -meridians, and the focus of knee tendon and its frequency were recorded by MSUS technique.

Higher Concentration of Plasma Glial Fibrillary Acidic Protein in Wilson Disease Patients with Neurological Manifestations.

Design, synthesis and antitumour evaluation of novel anthraquinone derivatives.

We report the design, synthesis, and biological evaluation of 13 new and 1 known anthraquinone derivatives which exerted cytotoxicity against PC3, A549 and NTUB1 cell lines. The results indicate that, among these 14, compounds-1 and 14 showed the highest growth inhibitory effect on NTUB1 and PC3 cells, respectively. Compound-1 at lower doses targets DNA, induces DNA damage and subsequently triggers G2/M arrest and apoptotic cell death at 24 h.

Background: The significance of () infection and atrophic gastritis (AG) in the prevalence of colorectal adenomas has been examined in a limited number of studies. However, these studies reported disputed conclusions.

Aim: To investigate whether infection, AG, and -related AG increase the risk of colorectal adenomas.

Quantitative assessment of postural instability in spinocerebellar ataxia type 3 patients.

Objective: Spinocerebellar ataxia type 3 (SCA3) is one of the most common hereditary neurodegenerative diseases, with balance instability as main symptom. Balance quantification is crucial for evaluating the efficacy of therapeutic interventions. However, balance evaluation in SCA3 is often subject to bias.

Temperature and isotope effects in the reaction of CHCHOO with methanol.

Carbonyl oxides, also known as Criegee intermediates, are generated from ozonolysis of unsaturated hydrocarbons in the atmosphere. Alcohols are often used as a scavenger of the Criegee intermediates in laboratory studies. In this work, the reaction kinetics of CHCHOO with methanol vapor was investigated at various temperatures, pressures, and isotopic substitutions using time-resolved UV absorption spectroscopy.

Criegee Intermediate Reaction with Alcohol Is Enhanced by a Single Water Molecule.

The role of water in gas-phase reactions has gained considerable interest. Here we report a direct kinetic measurement of the reaction of syn-CHCHOO (a Criegee intermediate or carbonyl oxide) with methanol at various relative humidity (RH = 0-80%) under near-ambient conditions (298 K, 250-755 Torr). The data indicate that a single water molecule expedites the reaction by up to a factor of three.

Overexpression of OqxAB and MacAB efflux pumps contributes to eravacycline resistance and heteroresistance in clinical isolates of Klebsiella pneumoniae.

This study investigated the characteristics and mechanisms of eravacycline resistance and heteroresistance in clinical Klebsiella pneumoniae isolates. A total of 393 clinical K. pneumoniae isolates were collected and subjected to eravacycline and tigecycline MIC determinations using the agar dilution method.

1-Hydroxy-3-[(E)-4-(piperazine-diium)but-2-enyloxy]-9,10-anthraquinone ditrifluoroactate induced autophagic cell death in human PC3 cells.

The autophagy of human prostate cancer cells (PC3 cells) induced by a new anthraquinone derivative, 1-Hydroxy-3-[(E)-4-(piperazine-diium)but-2-enyloxy]-9,10-anthraquinone ditrifluoroactate (PA) was investigated, and the relationship between autophagy and reactive oxygen species (ROS) generation was studied. The results indicated that PA induced PC3 cell death in a time- and dose-dependent manner, could inhibit PC3 cell growth by G1 phase cell cycle arrest and corresponding decrease in the G2/M cell population and induced S-phase arrest accompanied by a significant decrease G2/M and G1 phase numbers after PC3 cells treated with PA for 48 h, and increased the accumulation of autophagolysosomes and microtubule-associated protein LC3-ll, a marker of autophagy. However, these phenomenon were not observed in the group pretreated with the autophagy inhibitor 3-MA or Bafilomycin A1 (BAF), suggesting that PA induced PC3 cell autophagy.
