Background: This study aimed to compare the efficacy and safety of PD-1/L1 inhibitors combined with anlotinib versus PD-1/L1 inhibitors combined with bevacizumab as second-line treatments for advanced NSCLC patients.

Methods: A retrospective analysis was carried out on data from advanced NSCLC patients who received either PD-1/L1 inhibitors combined with anlotinib or PD-1/L1 inhibitors combined with bevacizumab as second-line therapy. Clinical outcomes, including Overall Survival (OS), Progression-Free Survival (PFS), Objective Response Rate (ORR), Disease Control Rate (DCR), and Adverse Events (AEs), were compared between the two treatment groups.

Reactive oxygen species (ROS) play essential roles in both physiological and pathological processes. Under physiological conditions, appropriate amounts of ROS play an important role in signaling and regulation in cells. However, too much ROS can lead to many health problems, including inflammation, cancer, delayed wound healing, neurodegenerative diseases (such as Parkinson's disease and Alzheimer's disease), and autoimmune diseases, and oxidative stress from excess ROS is also one of the most critical factors in the pathogenesis of cardiovascular and metabolic diseases such as atherosclerosis.

Higher alkanes are a major class of intermediate volatile organic compounds (IVOCs) emitted by vehicles, which have been considered as important precursors of secondary organic aerosol (SOA) in urban area. Dynamometer experiments were conducted to characterize emissions from gasoline and diesel vehicles in China. Three types of higher alkanes, namely acyclic, cyclic, and bicyclic alkanes, were explicitly quantified through the novel proton transfer reaction time-of-flight mass spectrometer with NO ionization (NO PTR-ToF-MS) with time response of 1 second.

Doramectin, a 16-membered macrocyclic lactone that is widely used in the treatment of mammalian parasitic diseases. Doramectin was produced by mutant using cyclohexanecarboxylic acid as a precursor. As a semi-synthetic insecticidal agent produced, the production of doramectin was low, which could not be satisfy the demands of industrial fermentation.

To investigate the influence of cations on the microstructural characteristics of electrochemical reinforcement in soft clay, a study was conducted using three different cationic salt solutions-NaCl, CaCl₂, and FeCl₃-for grouting treatment. Four sets of indoor experiments were performed to examine the reinforcement mechanism of the electrochemical method. The findings indicate that increasing the valence of injected cations significantly affects the electrochemical reinforcement effect and the soil's microstructural properties.

Background: Liuweizhiji Gegen-Sangshen oral liquid (LGS), as a Chinese medicinal preparation, is developed from a Traditional Chinese medicinal formula consisting of six Chinese medicinal herbs, including Puerariae lobatae radix, Hoveniae semen, Imperatae rhizoma, Crataegi fructus, Mori fructus and Canarli fructus, and has been extensively utilized in the prevention and treatment of alcoholic liver disease (ALD) clinically. Previous study has demonstrated that LGS dose-dependently mitigated ALD in rat models. However, whether and how the main characteristic constituents of LGS (the flavonoid and polysaccharide fractions, LGSF and LGSP) contribute to the anti-ALD effect remains unclear.

Objectives: Extensive-stage small cell lung cancer (ES-SCLC) suffering from brain metastases (BM) has a poor prognosis and lacks effective treatment selection. In this study, we explored the efficacy and safety of combination treatment of albumin-bound paclitaxel (nab-ptx), anlotinib, and PD-1/L1 inhibitors for such special population.

Methods: A total of 55 patients diagnosed with ES-SCLC and BM were enrolled in this retrospective study.

Objective: We aimed to quantitatively analyze the perfusion characteristics of pancreatic neuroendocrine tumors (pNETs) utilizing dual-source CT imaging.

Methods: Dual-source CT perfusion scans were obtained from patients with pNETs confirmed by surgical or biopsy pathology. Perfusion parameters, including blood flow (BF), blood volume (BV), capillary permeability surface (PS), mean transit time (MTT), contrast transit time to the start (TTS), and contrast transit time to the peak (TTP), were statistically analyzed and compared with nearby healthy tissue.

Effective treatment strategies for second-line therapy in extensive-stage small cell lung cancer (ES-SCLC) are currently lacking. For this reason, we collected and recorded efficacy and safety data from patients with ES-SCLC who had disease progression after first-line treatment and received albumin-bound paclitaxel, anlotinib, and immunotherapy. Preliminary data showed an objective response rate of 37.

Prostate cancer (PCa) has become a common disease among middle-aged and elderly men. The lipoxygenase (LOX) pathway plays a crucial role in the occurrence, development, invasion and metastasis of PCa and is therefore considered a new target for the prevention and treatment of PCa. 5-LOX and 12-LOX have a promoting effect on the occurrence, development, invasion and metastasis of PCa.

Article Synopsis
  • Amyotrophic lateral sclerosis (ALS) is a disease that leads to muscle weakness due to motor neuron loss, and apigenin (APG), an antioxidant, may help treat it.
  • In a study using a specific mouse model of ALS, APG showed positive effects by slowing weight loss and improving motor function, while also changing levels of key proteins related to oxidative stress and cell death.
  • The findings indicate that APG might combat ALS progression by affecting oxidative stress and cell survival mechanisms, warranting more research into its potential as a treatment.

Article Synopsis
  • - The cGAS-STING pathway is a crucial part of the immune system that detects both pathogens and abnormal self-DNA, acting as a defense mechanism against diseases.
  • - When DNA is recognized, cGAS creates a messenger called cGAMP, which activates STING, leading to various immune responses by relocating to specific cellular sites and activating transcription factors.
  • - Understanding the role of STING in immune responses and cancer can inform new therapies for cancer immunotherapy, balancing its immune-boosting effects with potential tissue damage.

As the role of RNA modification in gene expression regulation and human diseases, the "epitranscriptome" has been shown to be an important player in regulating many physiological and pathological processes. Meanwhile, the phenomenon of cancer drug resistance is becoming more and more frequent, especially in the case of cancer chemotherapy resistance. In recent years, research on relationship between post-transcriptional modification and cancer including drug resistance has become a hot topic, especially the methylation of the sixth nitrogen site of RNA adenosine-mA (N6-methyladenosine).

  • MurK is an amino sugar kinase that specifically phosphorylates MurNAc and GlcNAc sugars, which are important for cell wall turnover in Clostridium acetobutylicum, using ATP.
  • The study determined the crystal structures of MurK in complex with these sugars and glucose, revealing a V-shaped fold consisting of a small N-terminal and a large C-terminal domain, with a catalytic pocket between them.
  • Key residues were identified that contribute to MurK’s function and flexibility, showing that the enzyme changes shape when binding to MurNAc or GlcNAc compared to glucose, which affects its catalytic activity.

Matching the supply and demand of related ecosystem services can be an effective way to realize long-term sustainable management of the food-energy-water nexus (FEW Nexus) in drylands. However, few studies have focused on the matching of supply and demand for ecosystem services associated with advancing the sustainability of FEW-Nexus, there is limited research in this domain, which lacks systematic and quantitative analysis of the relationship between them and FEW Nexus sustainability. Here, this research takes the West Liaohe River Basin in the arid region of China as a case study.
