Herpetological surveys of locations in six districts of Timor-Leste(Dili, Baucau, Ermera, Liqui a, Manatuto, Viqueque) during 2010 led to the discovery of a new, high-altitude species of Cryptoblepharus from Ermera District, a new country record(Hemidactylus cf. tenkatei), and the recording of two previously unvouchered species(Python r. reticulatus and Liasis m. mackloti). In this article, we summarize these new records and present numerous new district records for Timor-Leste and four records for road-killed snakes seen in West Timor(Indonesia). With the addition of the results from our 2009 survey, the update presented herein increases the confirmed number of amphibian and reptile species for Timor-Leste to 47.

We report the results of five herpetological surveys during 2011-2013 that included visits to all districts of Timor-Leste （Aileu, Ainaro, Baucau, Bobonaro, Dili, Covalima, Ermera, Laut6m, Liquiga, Manatuto, Manufahi, Viqueque） except the Oecusse exclave. Our fieldwork culminated in the discovery of one putative new frog species （genus Kaloula）, at least five putative new lizard species （genera Cyrtodactylus, Cryptoblepharus, and Sphenomorphus）, and two putative new snake species （genera Stegonotus and Indotyphlops）. In addition, we present new distribution records of amphibians and reptiles for 11 of the country＇s 12 contiguous districts, along with additional natural history data. Results from our surveys increase the number of amphibian and reptiles known to occur in Timor-Leste from 22 species before our surveys began to over 60, including over 20 as yet undescribed species.

Coral-like structures of the Y_(3-x)Pr_(x)Fe_(5-y)Yb_(y)O_(12),(0.00 ≤ x ≤ 0.04, 0.00 ≤ y ≤ 0.02) compound were synthesized using the sol-gel method. Structural investigation certified the YIG cubic crystal structure formation, without any secondary phase. It is shown that, the relatively large ionic radius of the dopant cations results in an expansion of the lattice parameter, variations in the Iona-O-Iondangle, Iona-O,Iond-O and Ionc-O bond distances and decrease in the average crystallite size. Fourier transform infrared(FTIR) and Raman measurements are essential to testify the single-phase formation of YIG crystal structure and are observed changes in the stretching and vibrational modes, respectively. The morphological study, energy dispersive spectroscopy(EDS) spectra and textural properties show corallike structures, peaks associated with Pr^(3+) and Yb^(3+) atoms and the effect of dopants on surface area,diameter, and pore volume, respectively. The optical analysis from diffuse reflectance spectra witnessed an increase in the optical gap band, a decrease in Urbach energy and blue shift in the charge transfer,correlated with the expansion of the unit cell due to the dopant's insertion in the YIG structure. A typical ferrimagnetic behavior is exhibited by the Y_(3-x)Pr_(x)Fe_(5-y)Yb_(y)O_(12)compound. The saturation magnetization(M_(s)), cubic anisotropy constant(K_(1)) and coercive field(H_(c)) increase with the Pr^(3+)cations content, as consequence of their magnetic nature and distribution around of Fe^(3+)ions due to the coexistence with the Yb^(3+). Finally, for the first time, antibacterial tests by mean of the direct contact method were performed for YIG co-doped with Pr^(3+)and Yb^(3+)and it is shown that, relatively high dosages of Pr^(3+) cations favored the activity against S. aureus, therefore, a new biological property for YIG doped with rare earths is presented.

Primary liver lymphoma is extremely rare, in most of cases it is a B cell lymphoma. Usually the diagnosis is made in middle-aged individuals and most of them have a relatively short life expectancy. In this article, the authors present a case report of a 75-year-old woman with symptoms of three weeks of evolution of diffuse abdominal pain, asthenia and anorexia. The analysis showed cyto cholestasis and the radiological image with lush hepatomegaly because of a large hepatic mass. The patient started chemotherapy and actually is well twenty months after the end of the chemotherapy.

Exploitation and processing of pegmatoids at Brazil＇s northeast （Serido region-RN State） aiming further use as dimension stone produces mass losses ranging between 30%-90%. The tailings are predominantly composed by feldspar, quartz, muscovite and other Fe-bearing silicates such as biotite and amphiboles, suitable for ceramic production. The recovery of these elements depends on mica＇s remotion to levels under 2.0%, preferentially by dry methods due the scarce amount of water prevailing at Serido region. This paper presents results from pegmatite tailings characterization from Serido region showing the potentially application as raw material for ceramic production. To do it, a new technological route must be developed to fit it as main component to white ceramic industry, considering the properties required by ceramic industries.

Pyoderma gangrenosum is a rare ulcerative cutaneous disorder commonly associated with systemic diseases such as inflammatory bowel diseases. This paper reports a case of pyoderma gangrenosum affecting the mouth and the skin associated with ulcerative colitis. A Medline search in English literature from 1961 to 2012 revealed only 11 documented cases of pyoderma gangrenosum with oral involvement. Previous reported cases of oral cavity involvement have shown that the most common sites of manifestation are the tongue, palate, and tonsillar fauces. This case emphasizes the importance of including inflammatory bowel diseases and their manifestations in the differential diagnosis of ulcerative lesions in the oral cavity.
