The increasing economic losses associated with growth retardation caused by (EHP), a microsporidian parasite infecting penaeid shrimp, require effective monitoring. The internal transcribed spacer (ITS)-1 region, the non-coding region of ribosomal clusters between 18S and 5.8S rRNA genes, is widely used in phylogenetic studies due to its high variability.

Background And Objective: The ability to inhibit aggregation has been demonstrated with synthetically derived ginsenoside compounds G-Rp (1, 3, and 4) and ginsenosides naturally found in 20(S)-Rg3, Rg6, F4, and Ro. Among these compounds, Rk3 (G-Rk3) from needs to be further explored in order to reveal the mechanisms of action during inhibition.

Methodology: Our study focused to investigate the action of G-Rk3 on agonist-stimulated human platelet aggregation, inhibition of platelet signaling molecules such as fibrinogen binding with integrin αβ using flow cytometry, intracellular calcium mobilization, dense granule secretion, and thromboxane B secretion.

Major clinical symptoms of infection include fever, anemia, anorexia, jaundice, and decreased milk production. Although several studies have been conducted on tick-borne pathogens, including in Korea, only a few have focused on infection in deer, including the Korean water deer. Blood samples from 160 deer were collected and subjected to DNA extraction and polymerase chain reaction (PCR).

Article Synopsis
  • The white-spotted flower chafer extract (PBE) is traditionally used for liver issues and this study examines its effects on platelet aggregation.
  • PBE was found to inhibit the activation of integrin αIIb/β by influencing cyclic nucleotides, which are vital for platelet function.
  • The extract also impacted several signaling molecules in platelets, demonstrating strong antiplatelet effects that may help in preventing cardiovascular diseases related to thrombosis.

Background: The anti-platelet activity of the saponin fraction of Korean Red Ginseng has been widely studied. The saponin fraction consists of the panaxadiol fraction (PDF) and panaxatriol fraction (PTF); however, their anti-platelet activity is yet to be compared. Our study aimed to investigate the potency of anti-platelet activity of PDF and PTF and to elucidate how well they retain their anti-platelet activity via different administration routes.

  • The study investigates the use of autologous platelet lysate (A-PL) as a replacement for fetal bovine serum (FBS) in culturing canine mesenchymal stem cells (cMSCs), addressing ethical and scientific issues associated with FBS.
  • Results showed that varying combinations of A-PL and FBS did not negatively impact cMSC cell growth and viability, while enhancing their ability to differentiate into multiple cell types, particularly in the media with 10% A-PL.
  • These findings suggest that A-PL is a viable alternative to FBS, potentially improving the development of cMSCs for regenerative medicine under good manufacturing practices.

Platelets play a very significant role in hemostasis while simultaneously posing a risk for the development of various cardiovascular diseases. Platelet-mediated issues can occur in blood vessels and trigger various medical problems. Therefore, controlling platelet function is important in the prevention of thrombosis.

Article Synopsis
  • Macrophages play a significant role in the tumor microenvironment by influencing tumor malignancy, particularly in colorectal cancer.
  • Ionizing radiation (IR) enhances the production of IL-1β in macrophages through the activation of the NLRC4 inflammasome and caspase-1, which converts the precursor IL-1β into its active form.
  • The activation of this pathway is primarily regulated by p38 MAPK, as inhibiting p38 MAPK reduces IL-1β production and NLRC4 expression in macrophages exposed to IR and LPS.

Hypercoagulability is frequently observed in patients with severe coronavirus disease-2019 (COVID-19). Platelets are a favorable target for effectively treating hypercoagulability in COVID-19 patients as platelet hyperactivity has also been observed. It is difficult to develop a treatment for COVID-19 that will be effective against all variants and the use of antivirals may not be fully effective against COVID-19 as activated platelets have been detected in patients with COVID-19.

Article Synopsis
  • Ulcerative colitis (UC) is a chronic inflammatory disease of the colon that causes ulcers, and the study investigates the effects of a combination of Rg3-enriched Korean Red Ginseng extract (Rg3-RGE) and Pentoxifylline (PT) on UC in mice.
  • The research involved multiple groups of mice treated with various substances, including a control group and those exposed to inflammatory agents, to measure outcomes like colon length, body weight, and levels of inflammatory markers.
  • Results showed that the combination treatment of Rg3-RGE and PT significantly improved colon health, reduced inflammation, and enhanced immune cell function compared to the inflammatory model group, indicating its potential as a therapeutic option for UC.

Background: Since ginsenosides exert an anti-thrombotic activity, blood flow-improving effects of DK-MGAR101, an extract of mountain ginseng adventitious roots (MGAR) containing various ginsenosides, were investigated in comparison with an extract of Korean Red Ginseng (ERG).

Methods: In Sprague-Dawley rats orally administered with DK-MGAR101 or ERG, oxidative carotid arterial thrombosis was induced with FeCl (35%), and their blood flow and occlusion time were measured. To elucidate underlying mechanisms, the cytoprotective activities on rat aortic endothelial cells (RAOECs) exposed to hydrogen peroxide (HO) were confirmed.

Normal activation of platelets and their aggregation are crucial for proper hemostasis. It appears that excessive or abnormal aggregation of platelets may bring about cardiovascular diseases such as stroke, atherosclerosis, and thrombosis. For this reason, finding a substance that can regulate platelet aggregation or suppress aggregation will aid in the prevention and treatment of cardiovascular diseases.

Ginseng has been widely studied due to its various therapeutic properties on various diseases such as cardiovascular disease (CVD). Cardiovascular disease has been canonically known to be caused by high levels of low-density lipoproteins (LDL) in the bloodstream, in addition to the impaired vasodilatory effects of cholesterol. However, current research on CVD has revealed a cascade of mechanisms involving a series of events that contribute to the progression of CVD.
