  • Thailand Highlights 14Th to 26Th November 2019 (13 Days)
    Thailand Highlights 14th to 26th November 2019 (13 days) Trip Report Siamese Fireback by Forrest Rowland Trip report compiled by Tour Leader: Forrest Rowland Trip Report – RBL Thailand - Highlights 2019 2 Tour Summary Thailand has been known as a top tourist destination for quite some time. Foreigners and Ex-pats flock there for the beautiful scenery, great infrastructure, and delicious cuisine among other cultural aspects. For birders, it has recently caught up to big names like Borneo and Malaysia, in terms of respect for the avian delights it holds for visitors. Our twelve-day Highlights Tour to Thailand set out to sample a bit of the best of every major habitat type in the country, with a slight focus on the lush montane forests that hold most of the country’s specialty bird species. The tour began in Bangkok, a bustling metropolis of winding narrow roads, flyovers, towering apartment buildings, and seemingly endless people. Despite the density and throng of humanity, many of the participants on the tour were able to enjoy a Crested Goshawk flight by Forrest Rowland lovely day’s visit to the Grand Palace and historic center of Bangkok, including a fun boat ride passing by several temples. A few early arrivals also had time to bird some of the urban park settings, even picking up a species or two we did not see on the Main Tour. For most, the tour began in earnest on November 15th, with our day tour of the salt pans, mudflats, wetlands, and mangroves of the famed Pak Thale Shore bird Project, and Laem Phak Bia mangroves.

  • Bab I Pendahuluan
    BAB I PENDAHULUAN A. Latar Belakang Kanker adalah pertumbuhan sel yang abnormal disebabkan perubahan ekspresi gen yang mengarah ke disregulasi proliferasi sel, dan akhirnya berkembang menjadi populasi yang bisa menyerang jaringan serta bermetastasis ke tempat jauh, menyebabkan morbiditas dan jika tidak diobati mengakibatkan kematian (Ruddon. 2007). Kanker payudara merupakan salah satu pemicu terbesar kematian yang disebabkan oleh kanker. Tingkat kejadian kanker payudara merupakan tertinggi kedua di Indonesia setelah kanker leher rahim (Depkes RI. 2015). Beberapa faktor yang berperan dalam patogenesis kanker payudara yaitu faktor lingkungan dan genetik (Chodidjah. et al., 2014). Banyak strategi terapi yang digunakan untuk pengobatan penyakit kanker, contohnya agen kemoterapi. Namun, pengobatan dengan kemoterapi dapat menyebabkan toksisitas sistemik dan toksisitas jantung (Tyagi et al.. 2013). Adanya efek samping penggunaan kemoterapi mendorong usaha-usaha untuk menemukan obat dari bahan alam. Walaupun semakin berkembangnya metode kimia sintesis untuk menemukan dan memproduksi obat baru, namun potensi tanaman bioaktif atau ekstrak untuk menyediakan produk baru, pengobatan baru atau pencegahan penyakit masih sangat besar (Talib and Mahasneh.. 2010). Secara tradisional. masyarakat telah memanfaatkan keladi tikus (Typhonium flagelliforme) sebagai terapi kanker payudara (Chodidjah. et al.. 2014). Keladi Tikus merupakan tanaman herba yang dapat mengobati berbagai penyakit. seperti luka, penyakit paru-paru dan pendarahan (Mankaran et al.. 2013). Tanaman ini mengandung senyawa fitol dan turunan fitol (Lai et al.. 2008). Senyawa fitol memiliki aktivitas induksi apoptosis dengan mekanisme menurunkan regulasi Bcl-2 dan meningkatkan regulasi Bax (Song and Cho. 2015). Penelitian sebelumnya melaporkan bahwa ekstrak etanol 50% keladi tikus memiliki efek sitotoksik terhadap sel HeLa dengan IC50 30,19 µg/mL 1 2 (Purwaningsih et al.

  • Thailand Invitational 2017
    Field Guides Tour Report Thailand Invitational 2017 Feb 25, 2017 to Mar 18, 2017 Dave Stejskal & John Rowlett For our tour description, itinerary, past triplists, dates, fees, and more, please VISIT OUR TOUR PAGE. This shimmering Green-tailed Aethopyga is one of the fanciest sunbirds we saw on the tour! Photo by participant Fred Dalbey. It’s been two months now since our Thailand adventure closed and yet I live with persistent reminders of episodes from that trip that arise almost daily! No doubt, in part, because this was my first tour to this extraordinary country for birds, food, culture, and people (and now we know, butterflies!). And in part because I knew that ours was the last tour, after 21 wonderful years, that our heralded Asia guide Dave Stejskal would lead to Siam. Ouch, bite the man! Having the encounters, as we did, with so many legendary birds--Spoon-billed Sandpiper and Nordmann’s Greenshank, Silver Pheasant and Siamese Fireback, Great Hornbill and Silver-breasted Broadbill, Crested Jay and Ratchet-tailed Treepie, Sultan Tit and Giant Nuthatch, and overwhelming numbers of bulbuls, babblers, leaf warblers, and flycatchers--is enough to assure an exceptional birding tour. But to insure an experience of the highest quality, it was necessary to collect a stellar group of participants under the leadership of a first-rate guide and mix in some fabulous Thai food, some Siamese culture, and Dave’s good friend Wat with the best ground crew in the business in order to produce the kind of trip we in fact enjoyed. It was a humdinger.

  • History and Current Status of Systematic Research with Araceae
    HISTORY AND CURRENT STATUS OF SYSTEMATIC RESEARCH WITH ARACEAE Thomas B. Croat Missouri Botanical Garden P. O. Box 299 St. Louis, MO 63166 U.S.A. Note: This paper, originally published in Aroideana Vol. 21, pp. 26–145 in 1998, is periodically updated onto the IAS web page with current additions. Any mistakes, proposed changes, or new publications that deal with the systematics of Araceae should be brought to my attention. Mail to me at the address listed above, or e-mail me at [email protected]. Last revised November 2004 INTRODUCTION The history of systematic work with Araceae has been previously covered by Nicolson (1987b), and was the subject of a chapter in the Genera of Araceae by Mayo, Bogner & Boyce (1997) and in Curtis's Botanical Magazine new series (Mayo et al., 1995). In addition to covering many of the principal players in the field of aroid research, Nicolson's paper dealt with the evolution of family concepts and gave a comparison of the then current modern systems of classification. The papers by Mayo, Bogner and Boyce were more comprehensive in scope than that of Nicolson, but still did not cover in great detail many of the participants in Araceae research. In contrast, this paper will cover all systematic and floristic work that deals with Araceae, which is known to me. It will not, in general, deal with agronomic papers on Araceae such as the rich literature on taro and its cultivation, nor will it deal with smaller papers of a technical nature or those dealing with pollination biology.
