Lytic reactivation of EBV has been reported to play an important role in human diseases, including NPC carcinogenesis. Inhibition of EBV reactivation is considered to be of great benefit in the treatment of virus-associated diseases. For this purpose, we screened for inhibitory compounds and found that apigenin, a flavonoid, seemed to have the ability to inhibit EBV reactivation.

The lytic reactivation of Epstein-Barr virus (EBV) has been reported to be strongly associated with several human diseases, including nasopharyngeal carcinoma (NPC). Inhibition of the EBV lytic cycle has been shown to be of great benefit in the treatment of EBV-associated diseases. The administration of dietary compounds is safer and more convenient than other approaches to preventing EBV reactivation.

Nasopharyngeal carcinoma (NPC) is a malignancy derived from the epithelial cells of the nasopharynx. Although a combination of radiotherapy with chemotherapy is effective for therapy, relapse and metastasis after remission remain major causes of mortality. Epstein-Barr virus (EBV) is believed to be one of causes of NPC development.

(-)-Epigallocatechin-3-gallate (EGCG), a major green tea polyphenol, has been shown to inhibit the proliferation of a variety of tumor cells. Epidemiological studies have shown that drinking green tea can reduce the incidence of nasopharyngeal carcinoma (NPC), yet the underlying mechanism is not well understood. In this study, the inhibitory effect of EGCG was tested on a set of Epstein Barr virus-negative and -positive NPC cell lines.

Nasopharyngeal carcinoma (NPC) is a head and neck cancer prevalent throughout Southern China and Southeast Asia. Patient death following relapse after primary treatment remains all too common but the cause of NPC relapse is unclear. Clinical and epidemiological studies have revealed the high correlation among NPC development, Epstein-Barr virus (EBV) reactivation and host genomic instability.

Seroepidemiological studies imply a correlation between Epstein-Barr virus (EBV) reactivation and the development of nasopharyngeal carcinoma (NPC). N-nitroso compounds, phorbols, and butyrates are chemicals found in food and herb samples collected from NPC high-risk areas. These chemicals have been reported to be risk factors contributing to the development of NPC, however, the underlying mechanism is not fully understood.

The role of ionic currents on procaine-elicited action potential bursts was studied in an identifiable RP1 neuron of the African snail, Achatina fulica Ferussac, using the two-electrode voltage clamp method. The RP1 neuron generated spontaneous action potentials and bath application of procaine at 10 mM reversibly elicited action potential bursts in a concentration-dependent manner. Voltage clamp studies revealed that procaine at 10 mM decreased [1] the Ca2+ current, [2] the Na+ current, [3] the delayed rectifying K+ current I(KD), and [4] the fast-inactivating K+ current (I(A)).

to investigate the effects of 2'-hydroxy-4'-methoxyacetophenone (paeonol) on the electrophysiological behavior of a central neuron (right parietal 4; RP4) of the giant African snail (Achatina fulica Ferussac).
intracellular recordings and the two-electrode voltage clamp method were used to study the effects of paeonol on the RP4 neuron.
the RP4 neuron generated spontaneous action potentials.

Pemphigus vulgaris is a life-threatening autoimmune bullous dermatosis and its management represents a major challenge to medical teams. The primary treatments for pemphigus vulgaris are oral steroids and immunosuppressants, but topical approaches also play a role in disease management. Here, we report a patient with pemphigus vulgaris involving 62% of the total body surface area, with initial poor clinical response to systemic steroids and topical silver sulfadiazine therapy.

Atopic dermatitis (AD) is a chronic, relapsing dermatosis. Previous studies have focused mostly on pediatric patients, and investigations emphasizing adult AD have been limited.
We set out to determine the 1-year prevalence and evaluate the validity of the International Study of Asthma and Allergies in Childhood (ISAAC) and United Kingdom Working Party (UKWP) AD questionnaires of adult AD in Taiwan.

Hand eczema is a commonly encountered occupational disease and has a negative impact on life quality.
This study aimed to identify the specific conditions that may pose a higher risk for occurrence of hand eczema and evaluate the impact of hand eczema on life quality.
Nursing staff from a university hospital were invited to participate in a cross-sectional study.

In western countries, the Kirsten ras oncogene homolog gene (KRAS) mutation rate is high in patients with nonsmall cell lung cancer (NSCLC), especially in those with adenocarcinoma (30%-50%), but the epidermal growth factor receptor gene (EGFR) mutation rate is very low (3%-8%). In addition, KRAS mutations reportedly were associated with EGFR tyrosine kinase inhibitor (EGFR-TKI) resistance. In Taiwan, high EGFR mutation rates associated with high EGFR-TKI response rates in patients with NSCLC have been reported; however, KRAS mutation data are limited and have not been correlated with TKI response.

To evaluate the association of epidermal growth factor receptor (EGFR) gene copy number with EGFR and k-ras mutation status and tyrosine kinase inhibitor (TKI) sensitivity in non-small cell lung cancer (NSCLC), EGFR gene copy number of 182 NSCLC tumor specimens were analyzed by chromogenic in situ hybridization (CISH). EGFR and k-ras mutation analyses were also performed for, respectively, 176 and 157 of the 182 patients. Additionally, 36 patients in this study had received TKI monotherapy.
