Loco-regional treatment of hepatocellular carcinoma: Role of contrast-enhanced ultrasonography
World J Hepatol. 2022 May 27;14(5):911-922. doi: 10.4254/wjh.v14.i5.911. Epub 2022 Apr 7.ABSTRACTHepatocellular carcinoma (HCC) is one of the few cancers for which locoregional treatments (LRTs) are included in international guidelines and are considered as a valid alternative to conventional surgery. According to Barcelona Clinic Liver Cancer classification, percutaneous treatments such as percutaneous ethanol injection, radiofrequency ablation and microwave ablation are the therapy of choice among curative treatments in patients categorized as very early and early stage, while transcatheter arterial chemoembolization is ...

72-year-old woman with dyspnoea and pulmonary artery filling defects on CT angiogram
Wei Qin, pulmonologist and pulmonary vascular interventional radiology specialist A 72-year-old female patient was admitted because of dyspnoea and continuous cough lasting 5 months. She denied fever, chest pain and gastrointestinal symptom. She had undergone successful coronary stent implantation and percutaneous closure of the atrial septal defect 8 years ago. There was no history of venous thromboembolism, cancer, gastro-oesophageal reflux disease, asthma, allergic rhinitis or other allergies.At presentation, the patient’s temperature was 36.7 ℃ with a heart rate of 74 bpm, blood pressure of 110/60 mm Hg, r...

Different Immunoregulation Roles of Activin A Compared With TGF- β
Activin A, a critical member of the transforming growth factor-β (TGF-β) superfamily, is a pluripotent factor involved in allergies, autoimmune diseases, cancers and other diseases with immune disorder. Similar to its family member, TGF-β, activin A also transmits signals through SMAD2/SMAD3, however, they bind to distinct receptors. Recent studies have uncovered that activin A plays a pivotal role in both innate and adaptive immune systems. Here we mainly focus its effects on activation, differentiation, proliferation and function of cells which are indispensable in the immune system and meanwhile make some comparisons...

Electrochemical monitoring sensors of water pollution systems
This article describes electrochemical dye analysis beside the numerous electrochemical sensors utilized to identify these dyes as a food colorant and water. As a result, the qualities, chemistry, and toxicity of dyes as food colorants and industrial goods in Sudan have been investigated in this study. Sudan dyes have been thoroughly studied, and many electrochemical sensors have been developed to define and monitor these dyes in food colorants. As a result, current electrochemical sensors have been found to be neither mass-production nor cost-effective. Mostly, the synthesis of high-performance materials needs high knowle...

Myeloid-Derived Suppressor Cells: The Expanding World of Helminth Modulation of the Immune System
Infection with helminths or parasitic worms are highly prevalent worldwide especially in developing regions. Helminths cause chronic infections that are associated with suppression of immune responses to unrelated pathogens, vaccines, and by-stander antigens responsible for dysregulated immune responses as occurs in diseases such as allergies. Helminths use multiple mechanisms to modulate the immune system to evade the highly polarized type 2 immune response required to expel adult worms and for immunity to reinfection. Anthelmintic drugs are efficient in reducing adult worm burdens in helminth-infected individuals, but re...

Gut immune homeostasis: the immunomodulatory role of < em > Bacillus clausii < /em > , from basic to clinical evidence
Expert Rev Clin Immunol. 2022 Jun 8. doi: 10.1080/1744666X.2022.2085559. Online ahead of print.ABSTRACTINTRODUCTION: The gut microbiota affects the development of the gut immune system in early life. Perturbations to microbiota structure and composition during this period can have long-term consequences on the health of the individual, through its effects on the immune system. Research in the last few decades has shown that probiotic administration can reverse these effects in strain- and environment-specific ways. Bacillus clausii (B. clausii) has been in use for many decades as a safe and efficacious probiotic, but its m...
