Sunscreens today contain several synthetic UV (Ultraviolet) filter molecules to protect the skin epidermis from UV radiation damage. However, these molecules may create several negative effects on human skin. Due to this condition, there is an increase in the development of natural products to replace uses of these synthetic chemicals. Brown macroalgae Sargassum has been recently studied for its photoprotective activities. The purpose of this study is to investigate photoprotective activity of one of most abundant Sargassum species in Lombok coast; Sargassum cristaefolium. Spectrophotometry analysis with UV-VIS revealed the UV spectra absorbing capability of Sargassum cristaefolium (SC) in the UVA spectrum range (314–400 nm). Furthermore, spectrometry analyses with LC-MS revealed the existence of UV absorbing compound MAA-palythene. In correlation, SC ethanol extracts also demonstrate that it could protect DNA from UVA irradiation as analyzed in vitro in HeLa cell model. The effects of SC on UVA exposed-dorsal mice skin have also shown interesting results, as mice pretreated with SC before UVA exposure showed protective activity on the epidermal integrity similar as positive control. Whereas, UV exposed mice without SC or commercial products resulted in increased epidermal thickness, which is the common parameter of skin photoaging. In addition, pretreated mice with SC also show protective effects in the formation of collagen connective tissues. Overall, current results show promising photoprotective activity of SC against UV radiation. More advanced investigations of SC as a potential photoprotective agent would be reasonable for development of macroalgae-based natural skin protection products.

Abdominal aortic aneurysm (AAA) and intracranial aneurysm (IA) are serious arterial diseases in the aorta and brain, respectively. AAA and IA are associated with old age in males and females, respectively, and if rupture occurs, they carry high morbidity and mortality. Aneurysmal subarachnoid hemorrhage (SAH) due to IA rupture has a high rate of complication and fatality. Despite these severe clinical outcomes, preventing or treating these devastating diseases remains an unmet medical need. Inflammation and oxidative stress are shared pathologies of these vascular diseases. Therefore, therapeutic strategies have focused on reducing inflammation and reactive oxygen species levels. Interestingly, in response to cellular stress, the inducible heme oxygenase-1 (HO-1) is highly upregulated and protects against tissue injury. HO-1 degrades the prooxidant heme and generates molecules with antioxidative and anti-inflammatory properties, resulting in decreased oxidative stress and inflammation. Therefore, increasing HO-1 activity is an attractive option for therapy. Several HO-1 inducers have been identified and tested in animal models for preventing or alleviating AAA, IA, and SAH. However, clinical trials have shown conflicting results. Further research and the development of highly selective HO-1 regulators may be needed to prevent the initiation and progression of AAA, IA, or SAH.

High intensity of ultraviolet (UV) radiation causes several adverse effect such as erythema, sunburn, pigmentation, early senescence, and skin cancer. These effects can be prevented by using sun protection product. Wali (Brucea javanica L. Merr) is one of natural plants that contain phenol and flavonoid. These compounds are proven to have sunscreen effect. The purposes of this studies are to formulate and evaluate the effectivity of oil-in-water-type sunscreen cream using 1% ethanol extract of Wali seed. The sunscreen cream is developed by using a fusion method and the evaluation of the effectivity is conducted in vivo on the skin of mice (Mus musculus). The formulated sunscreen cream is then tested for its physical properties, including homogenity, pH, spreadability, adhesion, and stability. The effectivity of the formulated cream is also tested by observing the formation of erytema on the skin of mice (Mus musculus). Erythema appearing on the mouse skin is analyzed with ImageJ and SPSS v23 using the one way anova method. The results showed that the ethanol extract of Wali seeds could be formulated into sunscreen cream. Furthermore, the formulated cream was also able to protect the mice skin against the formation of erythema significantly compared to negative controls (p

The high ratio of population in Pamenang, Tanjung, and Gangga sub-districts compared to existing facilities and health workers is a very principle problem related to health education for the community, including information about medicine. One of whichis about the correct methods of how to get, use, save, and dispose medicines which is abbreviated with the DAGUSIBU program, including how to use special medicines. The aim of this socialization was to educate the patients in the public health center in Pemenang, Tanjung, and Gangga sub-districts about DAGUSIBU. The DAGUSIBU socialization program was carried out through the delivery of material, discussions, questions and answers, and demonstration by the audience and Pharmacists. Participants that incidentally were patients in public health centrewere very enthusiastic about this program as evidenced by the activeness of the participants in asking questions and answering questions about DAGUSIBU. Keywords: DAGUSIBU, socialization, Pemenang, Tanjung, Gangga, medicine
