Antibacterial efficacy of (makrut lime) essential oil against clinical multidrug-resistant methicillin-resistant and methicillin-susceptible isolates.

The increasing incidence of methicillin-resistant is a major public health concern. Recently, the performance of essential oil (CHEO) has been shown to contain broad-spectrum antibacterial activity. Therefore, this study aims to determine the antibacterial activity of CHEO alone and in combination with gentamicin against panels of clinical isolates of methicillin-susceptible (MSSA,  = 45) and methicillin-resistant (MRSA,  = 40).

In Silico Target Identification of Galangin, as an Herbal Flavonoid against Cholangiocarcinoma.

Cholangiocarcinoma (CCA) is a heterogenous group of malignancies in the bile duct, which proliferates aggressively. CCA is highly prevalent in Northeastern Thailand wherein it is associated with liver fluke infection, or (OV). Most patients are diagnosed in advanced stages, when the cancer has metastasized or severely progressed, thereby limiting treatment options.

Porcine placenta extract improves high-glucose-induced angiogenesis impairment.

Background: High glucose (HG)-induced reactive oxygen species (ROS) overproduction impairs angiogenesis that is one pivotal factor of wound healing process. Angiogenesis impairment induces delayed wound healing, whereby it eventually leads to amputation in cases of poorly controlled diabetes with diabetic ulceration. Porcine placenta extract (PPE) is a natural waste product that comprises plenty of bioactive agents including growth factors and antioxidants.

Gadd45β silencing impaired viability and metastatic phenotypes in cholangiocarcinoma cells by modulating the EMT pathway.

Growth arrest and DNA damage-inducible-β (Gadd45β) is a stress-response protein involved in a number of processes, including cell cycle control, DNA repair, survival and death control, and stress signaling, depending on its interactions. Gadd45β expression is dysregulated in numerous types of cancer, functioning as either a tumor promoter or a tumor suppressor. However, the functions of Gadd45β in cholangiocarcinoma (CCA), particularly in metastasis, has not been studied.

Establishment and characterization of a cholangiocarcinoma cell line (RMCCA-1) from a Thai patient.

Aim: To establish and characterize a new cell line derived from peripheral cholangiocarcinoma of a Thai patient.

Methods: The peripheral cholangiocarcinoma specimen surgically obtained from the patient was aseptically processed by washing and mincing before culturing in Ham's F12 medium containing 10% fetal bovine serum. After 3 mo, when the cell line has become homogeneous and stabilized, several features were investigated, including growth characteristics, immunofluorescence staining for cytokeratins, expression of tumor markers, chromosomal analysis by G-banding and multicolour fluorescence in situ hybridization (mFISH), in vitro migration and invasion characteristics.

Involvement of c-Met/hepatocyte growth factor pathway in cholangiocarcinoma cell invasion and its therapeutic inhibition with small interfering RNA specific for c-Met.

Background: Hepatocyte growth factor receptor (c-Met) plays an important role in many functions of cancer cells. We examined the roles of c-Met and its downstream signaling molecules in cholangiocarcinoma cell lines RMCCA1 and HuCCA1.

Materials And Methods: The expression of c-Met and their signaling cascades were determined in RMCCA1 and HuCCA1 cholangiocarcinoma cell lines by Western blotting.

Recrudescence in artesunate-treated patients with falciparum malaria is dependent on parasite burden not on parasite factors.

Artemisinin derivatives are first-line antimalarial drugs in Thailand. No firm evidence of clinically relevant artemisinin resistance exists. When used as monotherapy, artesunate has been associated with a high treatment failure (recrudescence) rate, which could be due to low-level artemisinin resistance.
