Abstract

This research aims to analyze the constraints and opportunities of livestock business development in  Aceh  Besar.  The  data  used  in  this  research  is  primary  data  obtained  by  distributing questionnaires to the related parties such as Animal husbandry in Aceh and Aceh Besar, breeders, breeders association and manager of slaughterhouse. The data analyzed by using SWOT analysis. The research found that the opportunity of livestock development is great enough beside the availability of land, government participation in giving seed (calf) of Aceh cattle to a number of breeders, mowers/feed crusher, vaccination, administration, artificial insemination and land development for forage. In addition, the constraints experienced by cattle breeders are limited which based on the infrastructure, poor management of cattle breeders, lack of cage sanitation, limited forage during dry season, and the demands of industry/manufacture are still dominated by imported beef.

Abstract

Some  of Trichoderma species  as  antagonistic  fungi  are  usually  considered  soil  microorganism, They  colonize  plant  roots,  some- times  forming  a  symbiotic  relationship.  Three  species  of Trichoderma (T. virens, T. harzianum and T. asperellum) have been inoculated on cacao seedling and  cocoa  pod. Trichoderma species  can  be  re-isolated  from  surface  sterilized  cacao  seedling, including the stem and leaf, root, and pod then observed their colonization ability. Fungal hyphae were observed under the microscope emerging from the leaf, steam, root of seedling and pod as soon as 1 day after their isolation from surface sterilized cacao seedling and pod. All Trichoderma species  were  able  to  enter  and  make  colonization.    The  highest  percentage  of  colonization occurred  in  the T.  harzianum by  73.3%  (leaves),  46.7%  (trunk)  and  86.7%  (roots).  While colonization  on the  skin  cocoa  pod  (epidermis)  also  has  a  different  percentage,  the  highest percentage indicated in the treatment of T. harzianum by 63.3%. We conclude that T. harzianum better  biological  control  agent  base  on  their  ability  to  colonize  all  part  of  seedling and  pod. Trichoderma species into the cacao stem, leaf, root and pod allowing systemic colonization of this tissue.

Abstract

Mesenchymal stem cells are adult non-hematopoietic stem cells with multilineage proliferation and differentiation capabilities. This type of stem cell has the multipotent ability to differentiate into osteocytes, tenocytes, adipocytes, chondrocytes and  bone marrow stromal cells. The migration mechanism of mesenchymal stem cell is not yet fully understood, but based on studies  that  have  been  done  recently  by  the  researchers  worldwide  shown  that  the inflammatory process plays an important role for mesenchymal stem cell migration. A number of chemokine that plays a role in the migration of mesenchymal stem cells such as MCP-1 (CCL2), CXCL8, RANTES (CCL5), LL-37, integrin β1, CD44 receptor, CCR2, CCR3, and tyrosine kinase receptors for the following growth factors: IGF -1, PDGF-bb, HGF and VEGF

Abstract

Malaria is one of the most severe public health problems worldwide. It is a leading cause of death and disease in many developing countries, where young children and pregnant women are the groups most affected. Malaria disease caused by Plasmodium parasite have symptoms that typically include fever, fatigue, vomiting and headaches. In severe cases, it can cause yellow skin, seizures, coma or death. The present study is aimed to monitoring parasitemia level and percentage of parasite morphology as parasitaemia progresses. This research used Plasmodium berghei NK strain obtained from National University of Malaysia which originally from MR4, USA. Design used in this research was completely randomized design, with 2 treatments which were mice without infection and mice with infection of P. berghei parasite. Method used in this research was staining method of thin smear of blood using Giemsa stained and observed by microscopic. Parameter of observation were morphology and development of P. berghei at different level of parasitaemia (10%, 20%, 30% and 40%). The result showed from microscopic examination of blood slides prepared from the study animals indicated that the ring form was dominant stage obtained at all different stages of infection followed by trophozoite stage. Meanwhile schizont stage was the lowest stage obtained at all different stages observed.

Abstract

Bulbs  of    localSamosir  Shallot  with  the  weight  ranging  from  1,3  to1,7  g  were  irradiated  by  several doses of gamma rays in order to investigate the radiosensitivity and the effects of irradiatons on the plants. Dry bulbs 2,5 months after harvest were exposed to gamma raysradiation ranging from 0 Gy to  20  Gy  to  determine  their  responses  to  radiation  stress  and  the  effective  radiation  dose  for identification of Lethal dose 50 (LD50). Percentage of shoot growth was measured on 35th days after planting. The variation in morphological and agronomic characters were also determined.  The results indicated  that  increasing  doses  of  gamma  irradiation  had  significant  effect  on  shoot  growth. Increasing  in  gamma  rays  doses  from  0  Gy  to  11Gy  had  little  effect  on  percentage  of  shoot growth.With  the  increase  in  radiation  dosesabove  11Gy,  agreat  reduction  in  percentage  of  shoot growth  was  observed  in  irradiated  bulbs  as  compared  to  control.  The  LD50  values  of  local  Samosir Shallot  determined  from  linear  regression  analysis  (using  Curve-fit  Analysis    software)  based  on percentage  of  regenerated  shoot  growth  was  11.60  Gy.  There  were  also siqnificantdifferenciesbetweenregenerated  plants  growth  from  irradiated  bulbs  and  control (unirradiated).Treated bulbs produced shorther plant lenght and less leave number

Abstract

The increase of elderly population in Indonesia leads to the drug misuse. The physiological change in geriatric become the major reason. It affects the change of    drug’s pharmacodynamic, pharmacokinetics and the harmful drug interaction among overly prescribed medication. Cardiovascular drugs produce the most common side effect in elderly patient. This study aims to observe the accuracy of cardiovascular drugs used based on its dose and drug interaction. The subject of this study are the 60 years old-or more- inpatients in Rumah Sakit Umum Zainoel Abidin’s (RSUDZA) Internal medicine ward who received cardiovascular drugs prescription. The data were collected from medical record and nurse’s drugs record. The analysis were performed descriptively by evaluate the drug interaction theoritically based on literature study and available concensuses. The result shows that the Potential interaction occurred  in 75 ( 68.18 % ) of cardiovascular drug used, and 22 (20 %) of whom are important potential interactions. The most frequent drugs that have the potential interaction in this study are furosemide , spironolactone, captopril, digoxin and aspirin

Abstract

Biopolymer-based nanocomposites containing bone minerals have been used intensively as bone- graft in various broken bone accidents. Main objective of this work is to prepare and characterise biocompatible chitosan/collagen/PVA nanocomposites containing calcium apatite suitable for bone-graft engineering. The calcium apatite nanofillers were prepared by calcination of cow bones at 830oC for 3 hours, followed by ball-milling and ultrasonication processes and characterization using particle size analysis (PSA) and electron scanning microscopy (SEM). It was found that particle siz of   the   filler  ranging  between  100-8000  nm   due   partial  aglomersation.  The   bone-graft nanocomposites specimens were prepared with various calcium apetite loading (0-10%) in constant ratio (1:1:1) of chitosan/collagen/PVA biopolymers. Compression strength of the nanocomposites containing optimum filler of 6% was found 2.01 MPa, its density was 1.19 g/cm3  and its water absorption capacity 58.3% and biodegradation rate 2.67%/day. Degree of biocompatibillity of the bone-graft was revealed after its implementation in mice tissue which did not show any histopathological effect after 14 days.
