Surgical intervention for patients with fibrinopurulent pleural empyema and acute respiratory failure: a case report.

Background: Fibrinopurulent thorax is a rare condition that can lead to respiratory failure. Fibroblastic decortication surgery has been shown to be an effective treatment for chronic empyema in previous studies. However, there is limited evidence supporting surgical intervention for fibrinopurulent thorax in cases of respiratory failure.

Efficacy and safety of perioperative sintilimab plus platinum-based chemotherapy for potentially resectable stage IIIB non-small cell lung cancer (periSCOPE): an open-label, single-arm, phase II trial.

Background: The absolute overall survival (OS) improvement with preoperative chemotherapy or chemoradiotherapy in locally advanced non-small cell lung cancer (NSCLC) patients is controversial and unsatisfactory. We designed this trial to explore the efficacy and safety of perioperative sintilimab plus platinum-based chemotherapy for potentially resectable stage IIIB NSCLC to facilitate further optimization of this therapeutic strategy.

Methods: Patients diagnosed with stage IIIB NSCLC through invasive staging approaches and/or PET/CT scans and evaluated as having a high probability of radical resection of the primary lesion and metastatic lymph nodes with clear pathological margins by a multidisciplinary team were enrolled in this open-label, single-arm, phase II trial at a single centre in China.

Transcriptomic analysis of regulatory mechanisms in the telogen-anagen transition of ovine hair follicles.

Background: Dorper sheep are celebrated for their fast maturation and superior meat quality, with some shedding their wool each spring. Wool shedding occurs naturally due to the hair follicle (HF) cycle, but its regulatory mechanisms remain unclear and need further investigation.

Results: In this study, shedding and non-shedding sheep were selected from the same Dorper flock.

Identification of PDLIM1 as a glioblastoma stem cell marker driving tumorigenesis and chemoresistance.

Glioblastoma (GBM) is an aggressive brain tumor with a poor prognosis, largely due to the presence of glioblastoma stem cells (GSCs). These cells drive tumor progression, recurrence, and chemoresistance, making them critical targets for therapy. This study aims to identify novel GSC markers for improved diagnosis and targeted treatment.

The analgesic effect of continuous adductor canal block combined with popliteal plexus block for total knee arthroplasty: a randomized controlled trial.

This study aimed to confirm the hypothesis that continuous ACB (CACB) combined with a popliteal plexus block (PPB) can improve posterior knee pain, reduce nalbuphine consumption, and shorten the length of hospital stay. Patients who underwent TKA were allocated to the CACB + sham block (SHAM) or CACB + PPB groups. The primary outcome was the maximum pain score originating from the posterior knee within 4 h after TKA.

Theoretical investigation of potential energetic material CL-20/TNBP co-crystal explosive based on molecular dynamics method.

Context: The exploration of CL-20 eutectic has been a subject of fervent interest within the realm of high-energy material modification.

Relationship between consumer acceptance, sensory characteristics, and physicochemical characteristics of "Fuji" apples from different origins.

This study examines the acceptance of young Chinese consumers for different "Fuji" apples, focusing on their sensory characteristics and physicochemical foundations. The sensory attributes of the samples were evaluated using a combination of static descriptive analysis (DA) and temporal check-all-that-apply fading (TCATA-fading) methods. Furthermore, the volatile compounds, soluble sugars, organic acids, and textural parameters of the samples were analyzed.

Variations in the Sensory Attributes of Infant Formula among Batches and Their Impact on Maternal Consumer Preferences: A Study Combining Consumer Preferences, Pivot Profile, and Quantitative Descriptive Analysis.

The sensory quality of infant formula (IF) has a significant impact on the preferences and purchasing behavior of maternal consumers. Consumer-based rapid descriptive methods have become popular and are widely preferred over classical methods, but the application of Pivot Profile (PP) in IF is still little explored. In this study, both Pivot Profile (PP) and Quantitative Descriptive Analysis (QDA) were applied to characterize the sensory profile of 12 batches of one-stage and three-stage IF with different storage periods, respectively, along with consumer preference data to determine the flavors contributing to liking.

Rapid detection of avian leukemia virus using CRISPR/Cas13a based lateral flow dipstick.

Avian leukemia virus (ALV) is one of the main pathogens of poultry tumor diseases, and has caused significant economic losses to the poultry industry since its discovery. Therefore, establishing a rapid detection method is essential to effectively prevent and control the spread of ALV. In this study, specific CRISPR RNA (crRNA) and recombinase-aided amplification (RAA) primers with T7 promoter were designed based on the relatively conserved sequence of avian leukemia virus.

Theoretical study of potential energetic material CL-20/DNAN eutectic explosive based on molecular dynamics method.

Context: The exploration of CL-20 eutectic has been a subject of fervent interest within the realm of high-energy material modification. Through the utilization of density functional and molecular dynamics methods, an investigation into the characteristics of hexanitrohexaazaisowurtzitane (CL-20)/2,4-dinitroanisole (DNAN) within the molar ratio range of 9:1-1:9 was conducted.

Molecular dynamics simulation of DNAN/DNB cocrystal PBXs.

Context: The DNAN/DNB eutectic is a high-energy explosive eutectic with superior safety and thermal stability compared to traditional melt-cast explosives. However, the addition of polymer binders can effectively enhance its mechanical properties, allowing for continued production demands without the need for changes to existing factory equipment. In this paper, a model of the DNAN/DNB eutectic explosive was established, and five different types of polymers-cis-1,4-polybutadiene (BR), ethylene-vinyl acetate copolymer (EVA), polyethylene glycol (PEG), fluorinated polymer (F2603), and polyvinylidene fluoride (PVDF)-were added to the (1 0 - 1), (1 0 1), and (0 1 1) cleavage planes, respectively, to form polymer-bonded explosives (PBXs).

Trade-off between sulfidated zero-valent iron reactivity and air stability: Regulation of iron sulfides by ammonium dihydrogen phosphate.

The reactivity and stability of zero-valent iron (ZVI) and sulfidated zero-valent iron (S-ZVI) are inherently contradictory. Iron sulfides (FeS) on the S-ZVI surface play multiple roles, including electrostatic adsorption and catalyzing reduction. We proposed to balance the reactivity and air stability of S-ZVI by regulating FeS.

An assessment of the sensory drivers influencing consumer preference in infant formula, assessed via sensory evaluation and GC-O-MS.

Consumer partiality for food products is related to purchase and consumption behavior, and are influenced by sensory preferences. The sensory and chemical drivers behind consumer preference in the infant formula (IF) were analyzed. A total of 31 aroma-active compounds were identified, playing an important role in the production of off-flavors (especially fishy).
