Radiation induced lichen planus - an uncommon side effect

Cutaneous lichen planus is classically characterized by violaceous, pruritic, planar papules and plaques, most commonly affecting the extremities. Lichen planus following radiation therapy is extremely rare and lichen planus following radiation therapy for prostate carcinoma has not been previously reported in the literature. We report a 66-year-old man who presented to the dermatology clinic with a symmetric pruritic eruption affecting the pelvic and gluteal region within two months of radiation therapy targeting the prostate and pelvic lymph nodes for prostate adenocarcinoma. The patient did not have a prior history of lichen planus. Physical examination demonstrated well demarcated, violaceous papules and plaques in a circumferential band-like distribution on the bilateral gluteal, lumbosacral, and pelvic region. In addition, he had a few discrete lesions on the calves and dorsal feet. Punch biopsy revealed an acanthotic epidermis with "saw-tooth" rete ridges and a lichenoid inflammatory infiltrate. A diagnosis of hypertrophic lichen planus was made, reinforcing the importance for clinicians to recognize radiation therapy as a risk factor for developing lichen planus despite no prior history of lichen planus

INDENTIFIKASI FAMILI ZINGIBERACEAE DI KAWASAN HUTAN GUNUNG BUA KERINCI

Zingiberaceae is a family of ginger plants found in the forest area of Mount Bua Kerinci. However, many species of the family have not been properly identified. This research aims to find out the type of family Zingiberaceae in the forest of Mount Bua Hill. This type of research is qualitative research with exploratory survey methods. The data collection techniques used are observation and documentation. The results showed that the family species zingiberaceae found are 5 clans and 9 Species namely Curcuma domestica (Turmeric), Zingiber aromaticum (Lempuyang), Etlingera elatior (Kecombrang), Curcuma Heyneana (Temu Giring), Curcuma aeruginosa (Black Meeting), Curcuma zedoria (White Meet), Zingiber cassumunar (Bangle), Amomun maximum (Cardamom), Kaemperia galanga (Kencur)

POTENSI BIOAKARISIDA EKSTRAK DAUN MIMBA (Azadirachta Indica) DAN BUNGA CENGKEH (Syzygium Aromaticum) TERHADAP TUNGAU PENYEBAB PENYAKIT KREPES PADA JAMUR KUPING

Wood ear mushrooms  is commonly known as one of the cultivated edible mushrooms in Indonesia. The demand for this commodity is still steadily high and leads mushroom farmers to optimize its cultivation. For mushroom farmers in Yogyakarta, the prevalence of krepes disease which is caused by a group of species belongs to Acarina order is still high and leads to total loss of harvest. In order to diminish these Acarina species, the use of chemical acaricides is common because of their effectiveness in eradicating the pests despite their toxic effect to the environment. A strategy to provide environmental friendly acaricides which are  extracted from plants is therefore important. This research aimed to study the potency of neem leaves (Azadirachta indica) and clove flowers (Eugenia caryophyllata) extracts as bioacarisides for Acarina species as the causal agent of krepes disease. Neem leaves and cloves flowers were extracted using maceration and soxhlet extraction  methods, using 96% methanol as their solvents. Obtained crude extracts would then be subjected to phytochemical analysis using qualitative biochemical tests and GC-MS. The effectivity of extracts as bioacaricides were tested both in in vitro and field scale. In vitro tests showed that neem leaves extract and clove flower extract had LC50 value ​​of 0.22% and 0.48% respectively. Field scale test on mushroom baglogs showed that the efficacy of the neem leaves and clove flower to eradicate acarina were above 50%. Taken together, neem leaves and clove flower extracts are potential to be used as bioacaricides in mushroom farming.Wood ear mushrooms  is commonly known as one of the cultivated edible mushrooms in Indonesia.

Environmental Kuznets Curve and Pollution Haven Hypothesis

There has been limited empirical work done in the recent past to test the hypotheses of EKC and PH. Results obtained in this paper validate EKC hypothesis for total carbon dioxide emissions and carbon dioxide emissions from liquid fuel consumption from a panel of countries. This is robust to inclusion of additional covariates and division of countries on the basis of income. Financial development increases total emissions in high income countries whereas it decreases emissions in non high income countries in the long run. Trade to GDP ratio does not affect emissions significantly in case of high income countries. In case of non high income countries, trade to GDP ratio increases the emissions from solid fuel in the long run. Also in case of non high income countries increase in trade to GDP ratio increases total emissions and emissions from liquid fuel consumption in short run. Therefore, there is evidence in favour of pollution haven hypothesis in short run. It is logical as we expect the emissions shifting aspect of trade to be operative in short run whereas in long run the trade should be determined by comparative advantages

Problematika Dalam Pembelajaran Berbasis Virtual Learning Environment (VLE) Terhadap Siswa dan Guru SMA/MA Pada Materi Biologi Di Masa COVID-19

The research aims to find out the problem of Learning based on Virtual Learning Environment (VLE) for high school / MA students in biological materials in the COVID-19 era. This research is qualitative research with a fenomenology approach. Data collection techniques in research are observations, interviews, and questionnaires. The technique of ensuring the validity of data is triangulation. Data analysis techniques are data reduction, data presentation, and data verification. The results of the study can be concluded that SMA Negeri 12 Kerinci students have difficulty in understanding the concepts and learning materials and teachers has difficulty in practicing and evaluating learning outcomes, SMA Negeri 4 Kerinci students lack motivation and participation in learning and teachers have difficulty in making teaching materials, and MAS Koto Rendah students often experience internet network disruptions, students are less active in learning, and students have low motivation to learn virtually and teachers have difficulty in making teaching materials and explaining materials
