Trigeminal neuralgia is a debilitating disease that can lead to depression and even suicide. Trigeminal neuralgia is usually treated using carbamazepine; however, many patients are refractory to such medical treatment. Thus, other treatment modalities are required, such as physical treatment and dry needling. The objective of this case report is to describe the management of trigeminal neuralgia in a 35 years old Malay housewife, who had left side atypical trigeminal neuralgia involving V2 region in the last four years, which was refractory to medical treatment. The appli- cation of Malay massage, combined with dry needling executed along the distribution of trigeminal nerve showed an improvement of pain on the Visual Analog Scale (VAS) from 7–8/10 to 0-1/10 after 11 sessions. Therefore, Malay massage combined with dry needling can be used as a non-pharmaceutical approach to managing trigeminal neu- ralgia.
Increasing demands for stingless bee honey in Malaysia have prompted alternative method using plastic cups as artificial
honey pots within beehives to enhance yield. However, honey’s acidity may lead to migration of plastic additives, affecting
body’s physiological responses on prolonged consumption. This study was performed to determine the presence of dibutyl
phthalate (DBP) and oleamide in stingless bee honey collected from plastic cups. A method for simultaneous extraction
and detection of both analytes by solvent terminated dispersive liquid-liquid microextraction (ST-DLLME) coupled with high
performance liquid chromatography (HPLC) was developed. Good linearity was observed with coefficient of determination
R2
≥ 0.97 in the concentration range of 0.5-50 and 10-250 µg/g for DBP and oleamide, respectively. The limit of detection
for DBP was 0.15 µg/g; while oleamide was 4 µg/g. The limit of quantitation for DBP and oleamide was 0.5 and 11 µg/g,
respectively. DBP and oleamide were not detected in all the honey samples collected.
CD4+CD25+ Foxp3+ T regulatory cell (Tregs) represents approximately 8-10% of the total CD4+ T cell population and are important for immune homeostasis and preventing autoimmune development. Thus, harnessing their functions as immune modulator may be coupled with the rapid advancement of nanotechnology development. Plant-mediated biosynthesis of silver nanoparticle (AgNP) is noteworthy due to simplicity, rapid rate and potentially render more biocompatibility with biomolecules. This study identified the effect of biosynthesized-AgNPs from Garcinia atroviridis (GA) in modulating inflammatory properties of Treg cells in Non-Obese Resistant (NOR). GA extract was used to biosynthesized AgNPs and was tested on the effect of inducing inflammatory properties in CD4+IL17Rhigh cells following 72hr in vitro treatment. Methods: Conventional CD4+CD25-Foxp3- cells from female NOR mice were sorted using magnetic separation and cultured in RPMI in the presence of anti-CD3/CD28 antibodies, TGF-β and IL-2 cytokines. Cells were then treated with or without GA-AgNPs for 48hr of iTreg cell induction and then re-cultured with new media treated with respective treatments received. After 72hr in vitro culture, cells were stained with fluorochrome-conjugated antibodies for flow cytometry. Results: Current result showed that AgNPs suppress CD4 expression in CD4+IL17Rhigh population. MAPK pathway proteins remain unchanged in both control and AgNP-treated groups. Conclusions: The preliminary findings may suggest the properties of GA-AgNPs in modulating CD4+ T cell population in normal condition. Further studies are necessary to elucidate the molecular mechanisms involve in such interaction. Current findings serve as basis in further identifying the immunomodulatory profile of nanoparticle for potential therapeutic use.
