Formation of a unique glass by spark plasma sintering of a zeolite
Authors: Wang Lianjun , Jiang Wan , Chen Lidong , Shen Zhijian
Published: September 2009

A simple approach, order–disorder transition (ODT), has been developed to synthesize a novel glass using ZSM-5 as starting materials. In this process, the ZSM-5 powders were pressed uniaxially in a graphite die and rapidly sintered using spark plasma sintering (SPS). High-resolution transmission electron microscopic images revealed that a few crystalline zeolite fragments were still preserved locally inside the SPS consolidated sample. Vickers microhardness and fracture toughness of this as-prepared transparent glass sample at room temperature reaches 7.3 ± 0.2 GPa and 2.0 ± 0.3MPa·m1/2, respectively. It is very interesting that these novel bulk transparent glasses exhibit ultraviolet photoluminescence (PL) properties at about ∼360 nm.
Reverse Monte Carlo structural model for a zirconium-based metallic glass incorporating fluctuation microscopy medium-range order data
Authors: Hwang Jinwoo , Clausen Anna M. , Cao Hongbo , Voyles Paul M.
Published: September 2009

We used reverse Monte Carlo (RMC) modeling to simulate the atomic structure of a Zr-based bulk metallic glass (BMG), incorporating short-range structural data from the electron diffraction total reduced density functionG(r) and medium-range structural data from fluctuation electron microscopy (FEM). Including the FEM data created within the model loosely ordered planar atomic arrangements covering regions ∼1 nm in diameter without degrading the agreement withG(r). RMC refinement against onlyG(r) produced no agreement with FEM. Improved simulations are needed to create fully realistic BMG structures, but these results show that including FEM in RMC further constrains the structure compared withG(r) data alone and that the FEM signal in real materials is likely to arise from pseudo-planar arrangements of atoms.
Method for preparing dispersed crystalline copper particles for electronic applications
Authors: Halaciuga Ionel , LaPlante Sylas , Goia Dan V.
Published: September 2009

Dispersed crystalline copper particles were prepared by reacting aqueous dispersions of CuCl with ferrous citrate. We report that the Fe(II) citrate complex can reduce rapidly and completely cuprous chloride to metallic copper and propose a mechanism for the reaction observed. By changing the precipitation conditions, copper particles with sizes varying from 250 nm to 2.0 µm were obtained. The method described represents a simple and versatile approach for preparing copper powders for electronic applications.
Nb effects on the structural and mechanical properties of TiAl alloy: Density-functional theory study
Authors: Liu Yongli , Li Hong , Wang Shaoqing , Ye Hengqiang
Published: September 2009

Nb can improve the oxidation resistance of TiAl; however, the reported concomitant effects on the mechanical properties are controversial. Therefore, the effect of different Nb additions (0∼20.83 at.% Nb) on the lattice distortion as well as dislocation nucleation and mobility of TiAl were examined by density-functional theory calculations to solve the puzzle. The calculation of the formation energy and c/a ratio showed that Nb slightly decreases the phase stability and enhances the anisotropy. The variation of shearing energy barrier demonstrates an interesting staged strengthening effect of Nb on TiAl. Further analyses of the charge density difference and the partial density of states reveal that the physical origination is the electronic anisotropy, which is correlated with the Nb content and distribution.

Study Objective. To evaluate the efficacy, safety, and costs of rabbit antithymocyte globulin (TMG) induction in patients who received kidney transplants from living unrelated donors.

Design. Retrospective cohort study.

Setting. Large academic medical center.

Patients. Eighty‐seven patients who received kidney transplants from living unrelated donors: 40 of the recipients underwent transplantation between January 1, 2003, and December 31, 2004, and did not receive TMG induction (no induction group); 47 underwent transplantation between January 1, 2005, and June 30, 2006, and received TMG induction (induction group). All patients received cyclosporine‐based immunosuppression.

Measurements and Main Results. Biopsy‐proven acute rejection, posttransplantation complications, and inpatient hospital costs for the first 12 months after transplantation were compared between groups using standard univariate statistical analyses. Induction significantly decreased the occurrence of biopsy‐proven acute rejection versus no induction (2% vs 48%, p<0.001). Fifty percent of rejection episodes in the no induction group required hospitalization, and 46% of rejection episodes required TMG treatment. Slightly elevated initial costs associated with TMG induction were offset by lower costs related to rejection treatment. Total inpatient costs for the 12 months after transplantation were comparable between the groups (no induction $66,038 vs induction $74,183, p>0.05). For the no induction versus induction groups, no significant differences in cytomegalovirus disease (5% vs 6%), malignancy (3% vs 2%), graft failures (5% vs 6%), mortality (5% vs 4%), and serum creatinine concentrations (mean ± SD 1.4 ± 0.3 vs 1.5 ± 0.3 mg/dl) were observed at 12 months (p>0.05 for all comparisons)

Conclusion. Five‐day TMG induction effectively reduced the 1‐year acute rejection rate without significantly increasing total inpatient costs or posttransplantation complications among recipients of kidney transplants from living unrelated donors
Treatment of Hepatorenal Syndrome
Authors: Kiser Tyree H. , MacLaren Robert , Fish Douglas N.
Published: September 2009

Hepatorenal syndrome (HRS) is a type of renal failure that occurs in patients with advanced cirrhosis. It is a result of splanchnic arterial vasodilation, renal vasoconstriction, reduced effective arterial volume, and potentially reduced cardiac output. Often, HRS is a fatal complication, and the only definitive treatment currently available is liver or liver‐kidney transplantation. A number of other treatment modalities have been tested for the management of HRS, but most evidence is derived from small noncontrolled studies. The primary role of these treatment options is to provide a bridge to liver transplantation. Treatment may also provide acute reversal of renal failure and some symptomatic relief, but relapse is a common occurrence. The best therapeutic options appear to be those that reverse portal hypertension, splanchnic vasodilation, and/or renal vasoconstriction. Vasopressin analogs, particularly terlipressin, have emerged as the preferred pharmacologic therapies for management of HRS. Albumin is an appropriate adjunctive therapy to terlipressin and can be used to prevent HRS in patients with spontaneous bacterial peritonitis. Transjugular intrahepatic portosystemic shunt may provide a surgical option for qualified patients with HRS. Octreotide is ineffective as monotherapy but may be used as adjunctive therapy to other vasoactive agents. Dopamine agonists, endothelin antagonists, natriuretic peptides, and nitric oxide synthase inhibitors have not been effective for reversing HRS. Artificial hepatic support therapies have demonstrated the ability to improve laboratory abnormalities in patients with HRS, but their effect on clinical outcomes has not been determined. The role of renal replacement therapies or the newer artificial hepatic support therapies need further evaluation before they can be routinely recommended.
Tenofovir for the Treatment of Hepatitis B Virus
Authors: Jenh Alice M. , Thio Chloe L. , Pham Paul A.
Published: September 2009

Tenofovir disoproxil fumarate is a nucleotide analog reverse transcriptase inhibitor recently approved by the United States Food and Drug Administration (FDA) for the treatment of chronic hepatitis B virus (HBV) infection in adults. Tenofovir has been available in the United States for the treatment of human immunodeficiency virus (HIV) since 2001. It blocks HBV replication in liver cells and is available as a once‐daily oral formulation. The efficacy of tenofovir for the treatment of chronic HBV has been demonstrated to be superior to adefovir in randomized controlled trials, which led to its FDA approval for use in chronic HBV Because of its potent antiviral activity, favorable safety profile, and higher barrier to the development of resistance, tenofovir should replace adefovir as a first‐line monotherapy option in the treatment of HBV in monoinfected patients. In the HIV‐HBV‐coinfected population, tenofovir is already a preferred agent in combination with other anti‐HBV agents (lamivudine or emtricitabine), which are cotreatments for HIV as well. In addition, tenofovir monotherapy or in combination with nucleoside analogs are options for patients who have developed resistance to other therapies for chronic HBV, including lamivudine and adefovir.

Contemporary Imaging in Sarcoma
Authors: Landa Jonathan , Schwartz Lawrence H.
Published: September 2009

Learning Objectives

After completing this course, the reader will be able to: Evaluate the current use of specific modalities for diagnosis and staging of sarcoma.Enumerate advanced functional imaging techniques and compare their potential roles and limitations in the evaluation of sarcoma.Evaluate the role of imaging in assessing response to therapy in patients with sarcoma.

This article is available for continuing medical education credit at CME.TheOncologist.com

Sarcomas are a heterogeneous group of >50 subtypes of neoplasm. It is imperative to obtain appropriate imaging of these tumors in order to adequately assess, characterize, and stage bone and soft tissue sarcomas. Anatomic imaging such as radiographs, computed tomography, and magnetic resonance imaging (MRI) remain the foundation for both biopsy planning and postoperative evaluation of these neoplasms. However, anatomic imaging may not be entirely accurate in the evaluation of treatment response. Newer techniques, such 18F-fluorodeoxyglucose positron emission tomography, are being used to evaluate distant metastases. Newer radiopharmaceuticals, such as 18F-fluorodeoxythymidine, are being developed to assist in the differentiation between benign and low-grade malignant neoplasms. Newer functional imaging techniques, such as dynamic contrast-enhanced MRI and diffusion-weighted imaging, among others, are being developed to evaluate treatment response.

Non‐Surgical Periodontal Therapy Lowers Serum Inflammatory Markers: A Pilot Study
Authors: Hussain Bokhari Syed Akhtar , Khan Ayyaz Ali , Tatakis Dimitris N. , Azhar Mohammad , Hanif Mohammad , Izhar Mateen
Published: September 2009

Background: Evidence suggests an association between periodontal disease and coronary heart disease (CHD). C‐reactive protein (CRP), fibrinogen, and white blood cell (WBC) counts are markers of inflammation, and their systemic levels have been associated with CHD risk. This pilot study investigated the effect of non‐surgical periodontal therapy on systemic levels of CRP, fibrinogen, and WBC counts in subjects with CHD or no CHD (NCHD).

Methods: Twenty‐seven angiographically defined patients with CHD and 18 subjects with NCHD aged ≥40 years were recruited for the study. Periodontal disease was measured through the clinical parameters bleeding on probing (BOP) and probing depth (PD). All subjects received non‐surgical periodontal therapy that included oral hygiene instructions and subgingival scaling and root planing. Systemic levels of inflammatory markers (CRP, fibrinogen, and WBC counts) were measured prior to and 1 month after periodontal therapy.

Results: Seventeen subjects with CHD and 11 subjects with NCHD completed the study. Subjects with CHD or NCHD experienced significant reductions in BOP (59% and 34%, respectively; P <0.05) and PD (41% and 35%, respectively; P <0.05), with non‐significant intergroup differences (P >0.05). In all subjects, CRP, fibrinogen, and WBC counts were reduced significantly (21% to 40%) after periodontal therapy (P <0.05).

Conclusions: Periodontal treatment resulted in significant decreases in BOP and PD and lowered serum inflammatory markers in patients with CHD or NCHD. This may result in a decreased risk for CHD in the treated patients. These findings will allow pursuit of a large‐scale randomized intervention trial in this population.
Enamel Matrix Derivative Protein Stimulated Wound Healing via Phosphoinositide 3‐Kinase
Authors: Goda Seiji , Kaneshita Yuki , Inoue Hiroshi , Domae Eisuke , Ikeo Takashi , Iida Joji , Domae Naochika
Published: September 2009

Background: Enamel matrix derivative (EMD) protein has been clinically used for periodontal regeneration, but the molecular mechanisms are not clear. Previous studies suggested that the activation of phosphoinositide 3‐kinase (PI 3‐kinase) plays a key role in facilitating cell migration. Given that the migration of osteoblasts is one of the key steps in the wound‐healing processes, we hypothesized that EMD protein would stimulate osteoblast migration by activating PI 3‐kinase. In this study, we tested this hypothesis using MG‐63 cells as model systems to evaluate mechanisms of migration by stimulation with EMD protein.

Methods: Confluent MG‐63 cells were mechanically scratched using a sterilized 1‐mm pipette tip that removed the cells within a circular area. The wells were incubated for 24 hours in various stimulation conditions (25, 50, or 100 μg/ml EMD protein) with or without the PI 3‐kinase inhibitor wortmannin (1, 10, and 100 nM) or LY294002 (1, 10, and 100 μM). Migrated cells in the wound section were counted by randomly selecting three areas from one well. The activation of PI 3‐kinase by EMD protein was evaluated by the phosphorylation of Akt using Western blot analysis.

Results: Although EMD protein did not affect proliferation, it enhanced migration into wounds on MG‐63 cells. We showed that EMD protein enhanced the phosphorylation of Akt in a dose‐dependent manner. We demonstrated that the PI 3‐kinase inhibitors wortmannin and LY294002 blocked migration into wounds and the phosphorylation of Akt enhanced by EMD protein in MG‐63 cells.

Conclusion: These results demonstrated that the activation of PI 3‐kinase plays a key role in the EMD protein‐stimulated migration of osteoblasts.
Interleukin‐1 Gene Cluster Polymorphisms Associated With Periodontal Disease in Type 2 Diabetes
Authors: López Néstor J. , Valenzuela Carlos Y. , Jara Lilian
Published: September 2009

Background: Epidemiologic studies have shown an increased frequency, severity, and risk of periodontitis in patients with diabetes. Periodontitis is associated with certain interleukin (IL)‐1 gene cluster polymorphisms. Diabetes is a proinflammatory state with increased levels of circulating cytokines suggesting a causal role for inflammation in its etiology. Common genetic factors may be involved in the susceptibility for diabetes and periodontitis. We evaluated the relationships among IL‐1 gene polymorphisms, type 2 diabetes, and periodontitis.

Methods: One hundred twelve patients with diabetes and chronic periodontitis, 224 patients without diabetes but with chronic periodontitis, and 208 healthy subjects without periodontitis were studied. All received a clinical periodontal examination and assessment of standard periodontal parameters. IL‐1A −889, −1B +3954, and −1B −511 polymorphisms were identified by polymerase chain reaction (PCR) amplification followed by restriction enzyme digestion and gel electrophoresis. Variable numbers of IL‐1RN tandem repeats were detected by PCR amplification and fragment‐size analysis.

Results: The severity and extent of periodontitis was significantly greater in patients with diabetes than in patients without diabetes. No significant differences in IL‐1A −899, −1B +3954, or −1RN genotype frequencies were found between patients with diabetes and patients without diabetes. The IL‐1A −889 TT genotype (odds ratio [OR] = 2.90; 95% confidence interval [CI] = 1.20 to 7.02), IL‐1B +3954 TT genotype (OR = 3.54; 95% CI = 1.15 to 10.85), and IL‐1B −511 CC genotype (OR = 2.10; 95% CI = 1.25 to 3.58) were significantly associated with periodontitis. The presence of an IL‐1 positive genotype was significantly associated with periodontitis (OR = 1.61; 95% CI = 1.04 to 2.49). No interaction between smoking status and polymorphisms was found.

Conclusions: Periodontitis was significantly associated with some IL‐1 gene polymorphisms. No association between diabetes and IL‐1A and −1B gene polymorphisms was found.
Treatment of Multiple Areas of Gingival Recession Using a Simple Harvesting Technique for Autogenous Connective Tissue Graft
Authors: McLeod Dwight E. , Reyes Elio , Branch‐Mays Grishondra
Published: September 2009

Background: A clinical case is presented describing a simple approach to harvest a connective tissue graft from the palate. This technique involves partial palatal deepithelialization and procurement of a layer of thin and uniform abundant connective tissue to treat multiple areas of gingival recession.

Methods: A 52‐year‐old European American male was referred for treatment of root sensitivity associated with gingival recession stemming from toothbrush abrasion. The areas of gingival recession associated with teeth #18 through #22 and teeth #27 through #31 were classified as Miller Class III gingival recession. A tunnel technique was planned for both areas in the mandible. The right palate, which served as the donor site, was deepithelialized, and a large connective tissue graft ∼1 mm thick was harvested. A periodontal probe was used to pass the graft through the tunnel, and the grafted areas were sutured using one or two vertical mattress sutures per interdental area.

Results: The patient was followed until complete healing was achieved. At 3 months, there was improvement in gingival thickness, keratinized tissue width, and root coverage. Complete root coverage occurred in three of the 10 treated teeth, and the remaining teeth obtained 80% to 90% root coverage. The patient's root sensitivity symptoms were resolved.

Conclusions: The technique is practical and simple to perform. This approach, involving partial palatal deepithelialization and the applied tunnel surgical procedure, resulted in a successful clinical outcome with increased gingival tissue thickness, keratinized tissue, and root coverage.

Published: September 2009

The effect of different genotypes, sires and season on age at slaughtering mass of warm carcass sides, fat thickness measured on three points (withers back, rump) and percentage of meat in warm carcass sides of average mass of 74,17kg using Yugoslav standard method was investigated in this paper. Results obtained show that investigated traits had no variation between pigs of different genotype (P>0,05). Sires effected variation of age at slaughtering, fat thickness (withers, back, rump, back + rump) and percentage of meat in warm carcass sides of offspring (P<0,01). Slaughter season effected fat thickness measured on withers (P<0,01) and age at slaughtering (P<0,05). Age, fat thickness and percentage of meat depended on the mass of warm carcass sides. Evaluated heritability coefficients for investigated traits were in interval of medium to high.

Published: September 2009

We?ve studied different modified types of herringbone milking parlor - 2x3 2x4 and 2x5 with single or double milking apparatus. The purpose of this investigation was to establish some limiting factors in selection of different types of herringbone milking parlor. Basic criterion for this selection was that the herringbone-milking parlor was to be controlled by one milker. The time needed for different milking operations was measured by chronometer and chronography on the farm of the Institute of Animal Breeding in Stara Zagora, Bulgaria. We have established that:- The main factor for selection of the herringbone-milking parlor with single milking apparatus is continuity of the process of milking for all herds, including the organization of work.- The main factor for selection of the herringbone-milking parlor with double milking apparatus is the duration of machine milking of the cows.

Published: September 2009

The aim of the present study was to estimate the development of body and some body parts and internal organs of roe deer, from 1 year of age (fawn) to 2-3 years of age (Buck). Average body mass of fawn was 16.6 kg and of buck 26.4 kg. Body mass of buck was by 1.6 times greater than body mass of fawn. Similar growth intensity was established for body parts (thighs shoulders, loin and back). The proportion of parts in body and carcass mass was same in fawn and buck. The mass of internal organs (liver, lungs, heart and spleen) increased with age, but proportion in regard to body mass was same in case of fawn and buck. During the first three years of age, no significant changes in body proportion of roe deer were registered.
Variability of traits of growth and quality of pig carcass sides: Effect of the breed and sex
Authors: Pusic Milovan , Petrovic Milica
Published: September 2009

Investigation of the phenotypic variability of traits of growth and carcass quality was carried out on 865 fatteners (394 female animals and 461 male castrated heads) originating from 29 sires (9 breeds-crossbreds: SL- Swedish Landrace, VJ- Large White, KL - Canadian Landrace, KJ - Canadian Yorkshire D - Duroc, KD - Canadian Duroc, H - Hempshire, Hempshire x Duroc, Pietrain x Duroc) and 197 dams ( pure breed, two and three breed crosses). Investigation included following traits: age at slaughtering (UK), body mass at slaughtering (TMK), daily gain of body mass during life cycle (ZDP), mass of warm carcass sides (MTP), daily gain of carcass sides (DPP) quantity and content of meat in carcass sides (UKMP, USMP - according to Regulations,1985), total mass and ratio of leg+shoulder+loin (UMFO, UFO). Obtained results were processed using several models (Harvey, 1990) which included sire breed, dam breed, sex, age at slaughtering or mass of warm carcass (regression effect). Traits TMK, MTP, ZDP and DPP were regressed to average age at slaughtering (UK=224 days), and remaining traits to average mass of warm carcass sides (MTP=91,98 kg) All investigated traits varied under the influence of sire breed (P<0,01), however not under the influence of dam breed except UKMP and USMP (P<0,05, table 2). Statistically highly significant differences were determined in regard to average values of all traits between female animals and male castrated heads (P<0,01). All traits of carcass quality dependen on the mass of warm carcass sides (P<0,01). Greater body mass at slaughtering and same average age was determined for offspring of boars of following breeds: KD - Canadian Duroc, KL - Canadian Landrace, D - Duroc and KJ - Canadian Yorkshire since their growth was more intensive compared to average values of al other investigated fatteners. Offspring of boars of SL - Swedish Landrace, KL - Canadian Landrace and KD Canadian Duroc breeds had more meat in warm carcass sides (42,14 to 43,37%) compared to the general average (41,95%) determined for all investigated pure breed fatteners, as well as two, three and four breed crosses. The lowest quantity and content of meat was determined for offspring of Large White boars (37,65 kg and 41,01%). Gilts had lower ZDP and DPP and higher UKMP, USMP, UMFO and UFO compared to male castrated heads (table 4).

Published: September 2009

Phytopathological investigation of seed of three commercial red clover cultivars - K9, K17 and NS Kolubara, and two pre-treatments of seeds rinsing and surface disinfection of seeds (T1) and surface disinfection of seeds (T2) have determined that frequency of species within the genus Fusarium varied from 0 to 13%. By use of T1 pre-treatment the presence of Fusarium species on the seed was observed in neither of examined cultivars. In this pre-treatment the presence of 1% Penicillium spp. was observed on seed of cultivar K17 only, while the seeds K9 and NS Kolubara were non-infected. By use of T2 pre-treatment, the frequency of Fusarium species varied from 1 to 13%, depending on cultivar. From the seeds of all three examined cultivars, Fusarium verticillioides (2-13%) and F. proliferatum (2-6%) were isolated and from the seed of cultivar K9, F. oxysporum (4%) F. solani (2%) and undetermined Fusarium species (3%) were isolated, while F. subglutinans (1%) was isolated only from the seed of NS Kolubara. Besides Fusarium species, by application of pre-treatment T2, in all examined cultivars the species from genera Cladosporium (6-14%), Alternaria (6-7%) and Acremonium (1-5%) were isolated, and Penicillium spp. (1%) from the seed of cultivar K17. The results obtained indicate that frequency of mycobiota on the seed of red clover depended more on the seed pre-treatment than on the examined cultivars. Considering the significant differences gained in health state of seed by application of T1 and T2 pre-treatments, further investigations should be directed towards the development of method which would show real health state of seed, that is, natural contamination of seed. In this case it is the use of pre-treatment T1.

Published: September 2009

Eggshell quality was studied in two groups of Shaver hens (300 hens per group) 30 weeks of age. All hens received a basic diet of the same composition with pulverized limestone as a source of calcium. The experimental group received 2 g of granular limestone (particle size 1.1-1.4 mm) per hen per day during one week, adding on the concentrate in the afternoon. Significantly lower deformation (19 m), higher breaking force (4,1 kg) and shell thickness (39, 3 x 0.01 mm) were registered for eggs of experimental group of hens than for eggs of control group (24 m; 3.3 kg 36.5 x 0.01 mm, respectively). The results obtained in our investigation showed possibilities of eggshell strength improvement using 2 g of larger particle size of limestone as additional source of calcium.

Effect of plant Tribulus terrestris extract on reproductive performances of rams
Authors: Kistanova Elena , Zlatev H. , Karcheva V. , Kolev A.
Published: September 2009

Tribulus terrestris extract was added to the forage of 8 rams of Pleven Blackhead and Abaci breed once daily in dose l,5g per head for a period of 40 days. Semen parameters and sexual behavior during semen collection were evaluated. It was found that Tribulus terrestris extract improves semen quality of rams: the count of spermatozoids, time of viability and motility of sperms increase. The great number of born lambs after the use of treated rams for insemination confirms high fertility of their semen. All experimental rams manifested a good libido and active sexual behavior.

Published: September 2009

On one hundred and seventy four hens of two different breeds (Rhode Island Red and Greenleg Partridge) histochemical investigation of the m. biceps femoris were done. The histochemical results from this experiment have shown that genotype affected the percentage of the muscle fibres. The significantly higher percentage of red fibre, and a lower percentage of white fibre together with higher body weight in Rl 1 genotype can suggest an effect of higher mobile activity of Rl 1 on their muscle physiology. The size of red and white fibres did not show any statistically significant differences between both examined groups.

Steroid hormones concentration in the postovulatory follicles of the goose
Authors: Wojtysiak Dorota , Kapkowska Ewa , Pasciak Piotr , Zivkovic Branislav
Published: September 2009

The purpose of the present investigation was to measure the concentrations of progesterone (P4), androgens (A) and estradiol (E2) in follicular wall of the three largest postovulatory follicles. The major findings in the present study are: 1) the postovulatory follicles of the goose, which are not homologous with the mammalian corpus luteum, are an active endocrine tissue. 2) Follicular wall of postovulatory follicles can synthesize large amounts of progesterone and lesser amounts of androgens and estradiol. This study also suggest that the steroidogenic potential of the follicular cells was markedly reduced during the process of follicular regression.

Components of genetic variability and heritability of the number of rows per ear in silage maize
Authors: Secanski Mile , Zivanovic Tomislav , Todorovic Goran
Published: September 2009

The aim of this study was to estimate the following components for the number of rows per ear in silage maize: variability of inbred lines and their diallel hybrids, superior-parent heterosis and components of genetic variability and heritability on the basis of diallel hybrids. It was determined that the variability of this trait was significantly affected by a genotype, year and their interaction. Inbred lines ZPLB 402, ZPLB 403 and ZPLB 405 had a higher number of rows per ears than majority of hybrids in both years of investigation, which resulted in negative values of heterosis. The analysis of components of genetic variance indicates that the additive component (D) was higher that the dominant (Hi and H2) genetic variance while a positive value of the component F and frequency of dominant (u) and recessive (v) genes for the observed trait point out that dominant genes prevailed over recessive ones. Furthermore, this is confirmed by a dominant to recessive genes ratio in parental genotypes for the number of rows per ear (Kd/Kr>l) in both years. The evaluated average degree of dominance a/h^7d was below 1, indicating to a partial dominance in heritability of this trait in both years. Results of the Vr/Wr regression analysis point out to a partial dominance in heritability of the number of rows per ear. Moreover, a presence of non-allelic interaction was detected, which indicates to a need to study effects of epistasis as it can be more important in certain hybrids. The greater value of additive variance resulted in greater narrow-sense heritability for the number of rows per ear in both years of investigation (86.83% and 69.44%, respectively).

Dairy farming: Integration into Europe
Authors: Jovanovic Miomir , Bulatovic Bogdan , Despotovic Aleksandra
Published: September 2009

Because of the increasing trend in globalization in dairy farming resulting in joining and taking over some companies with the aim of rationalization of production and realizing greater market participation, it seems quite real to expect such a trend to appear in our country as well. After the process of privatization had been realized a significant part of Montenegrin economy fell into the hands of private owners. In such conditions it can be expected that efficiency and competitiveness of some producers of milk and dairy products in the Republic of Montenegro will be increased, since in previous period this industry was characterized by insufficient exploitation of already existing capacities for milk processing while the quality of milk was considerably under the standards prescribed by the European Union. Depending on the dynamics of entering Montenegro into international economy the national dairy industry must be ready to face the challenge which will certainly be imposed on it. The object of this paper was to try to find the answers to the two questions. First where we are now and where we will be in the next five years in order to improve the competitive potential of domestic dairy farming.

Investigation of the effect of certain paragenetic factors on fertility traits of bull dams of Simmental breed
Authors: Pantelic Vlada , Skalicki Zlatko , Latinovic D. , Petrovic Milan , Kucevic Denis
Published: September 2009

Investigation included bull dams of Simmental breed selected on farms of agricultural producers on the territory of the Republic of Serbia. Method of Least Squares - LSMLMW (Harvey 1987) was used for analysis of the effect of region and order of lactation on reproductive traits. Obtained results indicate the justification for investigation of paragenetic factors, since the knowledge of their effect can contribute to more objective evaluation of random effects. Regions had highly significant effect (P<0,01) on age at first conception, duration of service period and interval between calvings whereas no significant effect on duration of pregnancy was registered (p>0.05). The effect of region of breeding many factors are included and most important one is nutrition. Order of lactation as second factor investigated in this research had no effect on any of the fertility traits (p>0.05). General average of mean values of least squares for fertility was: for age at first conception 517.61 days, duration of pregnancy 285.51 days, duration of service period 108.98 days, interval between calving 395.34 days.

Published: September 2009

The main objective of this study was to investigate the importance of the sires effect on fenotypic variability of production traits of performance tested boars of Large White, Landrace. and Hampshire breeds of pig. The data used in this study were collected from 738 performance tested young boars at the PKB Pig Testing Station in Padinska Skela, from 1995 to 2001. Analysed traits were initial age (IA), final age (FA), test duration (TD), average daily gain on test (ADG), lifetime ADG (LADG), amount of total consumed feed (TF), feed conversion ratio (FCR), daily feed intake (DPI) and body composition traits taken by ultrasonic equipment PIGLOG 105 (backfat thickness - BF1 and BF2, muscle depth - MD and lean meat content - LM) Data was analysed by fixed models of least squares method. Analysis of variance showed that sires nested within Hampshire breed highly significant influenced all investigated traits. Growth, feed efficiency and body composition traits except muscle depth, were highly significant influenced by sires of Large White breed. All feed efficiency traits and muscle depth were not influenced by sires within Swedish Landrace breed.

Published: September 2009

This paper presents the results obtained in testing of new selection of four most important and most common species of legumes used for animal feeds in Serbia. Alfalfa, red clover, bird's trefoil and sainfoin are also high quality plants regarding both nutritive substances and yield of dry matter. We have investigated three new selections of alfalfa, two selections of red clover, two selections of bird's trefoil and one of sainfoin in relation to standard ones. Trial lasted two years (2003-2004), designed according to standard methods for testing and recognition of new sorts. The production of green mass through four cuts per year was determined, together with the variation coefficient among cultivars. In the cuts of the second year the quality parameters were determined by standard lab analyses. The content of protein in all three new selections of alfalfa was higher in relation to standard (16,01%). while the standard of red clover with 20,03% was better than new selection. New selections of bird's trefoil are of better quality than standard (22,08 %), which is the case also with sainfoin (19,71 %). On the basis of obtained production and quality parameters the assortment of perennial legumes will be enriched by new cultivars.

Results of production traits obtained from first calving cows and evaluation of the breeding value of bull sires of Simmental breed in Serbia. Data was analyzed using the method of least squares and for evaluation of bulls' breeding value mixed model of random sire effect (BLUP method). Based on obtained results it was established in statistical analysis that breeding region had highly significantly affected (P<0.01) the deviation of production traits from the general average. Considerable deviation from the general average was caused by the year and season of calving (P<0.05), and interaction of breeding region and calving season contributed to high variation in yield of milk and milk fat (P<0.01).
