Judul: Uremia pada anjing
Abstrak: Uremia adalah suatu keadaan peningkatan kadar urea didalam plasma darah yang melebihi dari kadar normalnya. Sering juga digunakan sebagai istilah klinik 'clinical uraemia yang berarti menunjukkan gejala kompleks yang terlihat pada kasus kegagalan ginjal baik yang akut maupun kronis, sehingga terjadi retensi nitrogen. Urea merupakan senyawa nitrogen bukan protein yang di- sintesis oleh hati sebagai hasil dari katabolisme protein. Urea tersebut kebanyakan diekskresikan melalui air kemih dan hanya sedikit yang lewat tinja ataupun keringat. Kadar urea darah anjing normal berkisar antara 10-30 mg/100 ml darah. Namun pada kasus uremia yang parah kadar urea bisa meningkat sampai 500 mg/100 ml darah. Uremia ini sering terjadi pada anjing-anjing sudah berumur tua atau anjing yang mengalami gangguan pada ginjalnya. ...

Judul: Studi Kasus: Morfopatologi Anjing Penderita Ehrlichiosis yang Disertai Sindrom Uremia
Abstrak: Ehrlichiosis adalah penyakit infeksius dengan morbiditas tinggi yang disebabkan oleh Ehrlichia canis pada anjing. Di sini menjelaskan tentang morfopatologi anjing jenis German Sheperd dan Labrador retrivier yang menderita Ehrlichiosis disertai uremia yang dating ke Divisi Patologi, Departemen Klinik, Reproduksi, dan Patologi, IPB University. Anjing ditemukan mati dengan perdarahan hebat di seluruh subkutis dan berbagai organ, edema subkutis di semua tungkai, jaringan lidah nekrotik, dan mukosa pucat. Studi kasus ini bertujuan untuk mengkaji perubahan patologi-anatomi dan histopatologi dari berbagai organ anjing sehingga diketahui perjalanan penyakit dan penyebab kematiannya. Sampel organ kedua ekor anjing meliputi jantung, paru-paru, lidah, lambung, usus, hati, limpa, dan ginjal dibuat preparat histopatologi dan diwarnai dengan pewarnaan Haematoksilin-Eosin. Hasil pemeriksaan patologi-anatomi menunjukkan kedua ekor anjing mengalami perdarahan di berbagai organ, bentuk jantung double apex, hipertrofi ventrikel kiri, chicken fat clot di ventrikel kanan dan kardiomiopati, kongesti paru-paru dan bronkitis, stomatitis ulseratif, gastritis ulseratif, enteritis mukopurulenta, hati ikterus dan kongesti, splenitis dan nefritis interstisial kronis. Hasil pemeriksaan histopatologi paru-paru menunjukkan bronkheolitis dengan banyak koloni bakteri dan sel radang netrofil, serta nefritis interstitialis kronis dengan glomerulopati. Kardiomiopati menyebabkan kegagalan jantung yang berakibat kongesti pada seluruh organ. Kematian pada kedua ekor anjing ini disebabkan sepsis, kegagalan fungsi organ terutama jantung, hemoragik shok, dan uremia.

Judul: Thermal Characteristics and Dynamics of Tropical Cyclone over Western North Pacific Ocean: A Case Study of Typhoon Songda (Chedeng) 2011
Abstrak: The frequent occasion of Tropical Cyclone (TC) over Western North Pacific (WNP) Ocean lies from 10˚N to 26˚N and 121˚E to 170˚E. Sources of TC development come from warm ocean temperature where latent heat is released during condensation processes and subsequently concentrated in the boundary layer. Relative humidity at 850-700 hPa is responsible to produce the most intense storm. Meanwhile, weak vertical wind shear between 850-200 hPa is one of the dynamical factors that lead to the development of TC. Pressure level of 850-200 hPa is chosen to minimize the thermodynamic effect in the lower troposphere. Typhoon Songda (Chedeng in the Philippines) or TSC lasted from May 18th to 30th, 2011 and strengthened into powerful Super Typhoon stage between May 24th and 27th. Long curving track and the exhibition of all sequences of TC life cycle, TSC is then considered as an ideal case of TC. The objective of the study with case of TSC is to investigate the role of thermal characteristics and dynamics on TC intensity. The research is carried out by using Advanced Research of Weather Research and Forecasting model (WRF ARW model) version 3.3. Two domains are employed in the model. The first domain situate from 02˚N to 40˚N and 118˚E to 149˚E and cover spatial resolution () of 33.1 km. The second domain situate from 09˚N to 27˚N and 119˚E to 132˚E with of 11 km. Timestep of the model () is 120 seconds. The model is supported by the following physical parameterization, i.e., Yonsei University Scheme (YSU) in the boundary layer, Kain-Fritsch scheme (KF) in the cumulus, and WRF Single-Moment 3-class scheme in the microphysics. Initial meteorological condition prior to the formation of the cyclone is generated using WRF ARW standard-release model. Sensitivity of the model output is obtained from a selected single-parameter change scenarios, namely, 10 % to 20 % decrease and increase of wind shear initial data at 850-200 hPa, and by 10 % to 20 % decrease of relative humidity initial data at 850-700 hPa. The result showed that the negative correlations between wind shear and intensity are found in wind shear scenarios. Wind shears of 10 ms-1 which lead to strengthening of the wind intensity in the early period of Typhoon development are found in wind shear scenarios. The effect of wind shear changes on wind intensity is statistically significant in the 20 % wind shear scenarios. During mature stage, weak wind intensity occurred when wind shear increase as given in the WRF standard-release and the 20 % decreasing scenario. Different situation is found in the 20 % increasing scenario where wind shear tend to weak and lead to strong wind intensity at this stage. Meanwhile, the reduction of moisture supply at 850-700 hPa resulting from 20 % decreasing relative humidity play a major role in the weakening of wind intensity and reduces mechanical energy of the cycle process as much as 300 J kg-1.
