Advanced filtration requires a cost-effective, highly efficient and environmentally friendly membrane fabrication to achieve excellent and extreme oleophobic and hydrophilic states with an appropriate surface functionalization approach. For an efficient oil-water separation, surface material and structure have been categorized as superoleophobic (high oil repellency) and superhydrophilic (strong affinity to water). This can be attributed to their selective mechanisms. In addition, it is very important to consider these key factors as they will imperatively provide a unique capability to exhibit surface roughness, stimulate low and high surface energy, and improve surface chemistry, which makes membranes function efficiently for the oil and water separation system. In this review article, the application of ceramic membrane for oily water treatment and the principle of superhydrophilic and superoleophobic ceramic membrane for oil-water separation are elaborated and, in addition, the current progress for the use of inorganic material to functionalize ceramic membrane surface based on physical and chemical methods is appraised. Finally, the challenges and outlook on the membrane for oily-water treatment are briefly examined.

The objective of the research was to evaluate the effect of particle pre-treatment on physical, mechanical, and durability of jatropha fruit hulls (JFH) particleboard. The pre-treatments included were immersing in cold water, hot water, and acetic acid solution. After each treatment, the particles were dried up to 3% moisture content. Urea-formaldehyde (UF) resin was used to fabricate particleboards with board size, thickness and density target of 25 cm by 25 cm, 0.80 cm, and 0.70 g/cm<sup>3</sup>, respectively. Board pressed at 130℃ for 10 minutes, and 25 kg/cm<sup>2</sup> pressure. The evaluation of particleboard followed the JIS A 5908-2003. Whilist their resistance to subterranean termite test (mass loss, mortality, antifeedant value and feeding rate) refers to the Indonesian standard (SNI 01.7207-2006). The physical and mechanical properties of particleboards showed that all pre-treatments decreased the pH of particles. Overall, all particle immersing treatments resulted of better physical and mechanical properties of particleboard than those of untreated ones. The acetic acid treatment resulted the best physical and mechanical properties of particleboard. Based on the mass loss of JFH particleboard, hot water and acetic acid treated particleboards were classified into weak resistance to subterranean attack. The other two treatments were classified into very weak resistance. Hot water treated particleboard provided the highest mortality and antifeedant as much as 87.40% and 34.20%, respectively. Based on antifeedant classification, hot water treated particleboards were classified into moderately strong resistance, while other treatments were categorized into weak resistance. The lowest feeding rate value (45.30 μg/termite/day) was attained by hot water treatment.

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) is a disorder associated with various drugs and characterized by cutaneous drug eruption, eosinophilia and systemic symptoms. The diagnosis poses diffi culties due to its heterogeneity and long latency period. We report a case of 25 year old male with medical history significant for stage four chronic kidney disease, recently started on allopurinol for hyperuricemia, presented with fever, generalized exfoliative dermatitis and jaundice. Laboratory examination revealed hypereosinophilia, hyperuricemia, elevated bilirubin and elevated liver enzymes. Magnetic resonance imaging revealed acalculous cholecysititis and gallbladder hydrops. He was successfully treated with oral methylprednisolone and bepotastine.
