Due to the codon bias of different species, codon optimization is usually carried out in the process of heterologous protein expression. At present, there are a variety of codon optimization tools. However, the optimized sequences may still have high or low points of local guanine and cytosine (GC) content, which is not conducive to the primer design of gene subcloning, and also makes it difficult to perform the experiment of synthesizing the whole gene with DNA fragments by polymerase chain reaction (PCR) reaction.

Paclitaxel is one of the main chemotherapic medicines against triple-negative breast cancer (TNBC) in clinic. However, it has been perplexed by paclitaxel resistance in TNBC patients, resulting in a poor prognosis. Abnormal protein glycosylation is closely related to the occurrence and progression of tumors and malignant phenotypes such as chemotherapy resistance.

The gene encodes a transmembrane prolyl 4-hydroxylase, which is responsible for the degradation of hypoxia-inducible transcription factors (HIF) under normoxia. Clinically, biallelic variants have been identified in patients with hypotonia, hypoventilation, intellectual disabilities, dysautonomia, epilepsy, and eye abnormalities (HIDEA syndrome). Seizure was one of the most prominent symptoms.

Article Synopsis
  • The study aimed to assess the effectiveness of the indocyanine green (ICG) retention test as a noninvasive indicator for identifying esophageal varices in patients with liver cirrhosis.
  • A total of 144 patients were analyzed, revealing significant differences in ICG retention and other clinical markers between those with small varices and those with medium or large varices.
  • The findings suggest that while ICG retention and platelet counts can help identify patients at risk for large varices, they cannot replace endoscopy but may assist in the evaluation process.

Objective: To investigate how reactive oxygen species (ROS) regulates the signal transduction of platelet activation and apoptosis, and to explore the relationship between platelet activation and apoptosis.

Methods: Platelets were directly stimulated with thrombin or pretreated with ROS inhibitor N-acetylcysteine (NAC) before being stimulated with thrombin, and then flow cytometry was used to detect the effects of thrombin and NAC on P-selectin expression, αⅡbβ3 activation, mitochondrial membrane potential depolarization, phosphatidylserine (PS) externalization, ROS expression and platelet aggregation.

Results: Thrombin could induce the production of ROS in platelets in a concentration- and time-dependent manner.

Gene cloning is an important step in investigating gene structure and function. To verify gene sequence, Sanger sequencing is used, which may produce several overlapping sequencing files that need to be merged before alignment to the target gene sequence is performed. Previously, we reported the Python program to Merge Sanger sequences (https://peerj.

  • Edaravone Dexborneol (EDB) is a combination treatment shown to have antioxidant and anti-inflammatory effects that may protect against stroke.
  • The study investigates how EDB can reduce neuronal death by altering the harmful activation of A1 astrocytes after cerebral ischemia.
  • Results indicate that EDB not only improves behavioral outcomes and neuronal survival in mice but also suppresses neurotoxic A1 astrocyte activation through the inhibition of the NF-κB signaling pathway.

Feeding rate is an important factor influencing the carbon and nitrogen input and greenhouse gas emission from aquaculture systems. However, the quantitative relationship between feeding rates and GHG emissions is still poorly understood. In this study, we conducted a laboratory-scale experiment to examine the impact of feeding rate (0%, 2%, 4%, 6%, and 8%) on the CH and NO emissions from a pond rice-fish co-culture system.

Objectives: To investigate the clinical epidemiological and drug resistance (DR) characteristics of lymph node tuberculosis (LNTB) in Hunan Province which locates in South-central China, and to provide scientific clues for effective prevention and treatment of LNTB.

Methods: We retrospectively collected LNTB patients with culture positive at Hunan Chest Hospital, the biggest TB reference hospital in South-central China, from January 2013 to December 2021. The multiple demographic, clinical and drug susceptibility data of patients were collected from the hospital's electronic patient records.

Background: The recurrence rate of liver cancer after surgery is high. Radiofrequency ablation (RFA) combined with transcatheter arterial chemoembolization (TACE) is an effective treatment for liver cancer; however, its efficacy in recurrent liver cancer remains unclear.

Aim: To investigate the clinical effect of TACE combined with RFA in the treatment of recurrent liver cancer.

Epithelial barrier impairment of intestinal inflammation leads to the leakage of bacteria, antigens and consequent persistent immune imbalance. Restoring the barrier function holds promise for management of intestinal inflammation, while the theragnostic strategies are limited. In this study, we developed a novel coating by catalase (CAT)-catalyzed polymerization of tannic acid (TA) and combined chelation network with Fe.

Introduction: CD24 is a highly glycosylated glycosylphosphatidylinositol anchored membrane protein that plays an important role in tumor progression. The aim of this study was to investigate the effect of abnormal expression of CD24 on the proliferation, migration and invasion of breast cancer (BC) cells, and the molecular mechanism of regulating CD24 expression in breast cancer.

Methodology: The bioinformatics method was used to predict the expression level of CD24 in BC and its relationship with the occurrence and development of BC.

Background: Oral cancer, which is caused by mucous membrane variation, represents a prevalent malignant tumor in the oral and maxillofacial region, posing a significant threat to patients' lives and safety. While surgical intervention stands as a cornerstone treatment for oral cancer patients, it carries the risk of incomplete treatment or high rates of postoperative recurrence. Hence, a multifaceted approach incorporating diverse treatment modalities is essential to enhance patient prognosis.

Gastric cancer (GC) has become the first malignant tumor with highest incidence rate and mortality of cancer in China, finding therapeutic targets for gastric cancer is of great significant for improving the survival rate of patients with GC. Recently, many of studies have shown that LncRNAs is involved in multiple biological progresses in the development of GC. This study, we screened for abnormally high expression of LncSHANK3 in GC through the TCGA database, and found that LncSHANK3 sponge adsorbs miR-4530, further competing with MNX1 and binding to miR-4530.

Berberine (BBR) is a principal component of known for its therapeutic potential in treating diseases such as type 2 diabetes mellitus (T2DM) and obesity. Despite the trace levels of BBR in plasma, it's believed that its metabolites play a pivotal role in its biological activities. While BBR is recognized to promote GLP-1 production in intestinal L cells, the cytoprotective effects of its metabolites on these cells are yet to be explored.

An efficient synthesis of (+)-peniciketal B has been accomplished in 15 steps from the commercially available materials atraric acid, acryloyl chloride, and (+)-homoallylic alcohol. A convergent synthetic approach that is quite concise for constructing either "hemisphere" of (+)-peniciketal B with a common intermediate is employed that relies on a cascade intermolecular FeCl-mediated "inner sphere" Michael-type reaction/double cyclization of an α,β-unsaturated ketone and substituted phenol to build the benzo-fused 2,8-dioxabicyclo[3.3.
