Temperature influence on the fish assemblage structure in a large lowland river, the lower Oder River, Germany
Authors: Wolter C. 
Published: March 2007

Abstract –  Water temperatures were expected to structure river fish assemblages by promoting: (i) offspring's growth and densities in warm years, (ii) spring spawning fish when temperatures increase early and (iii) improved growth and overwintering condition from elongated vegetation periods. Favourable temperature conditions in their first year should improve growth and survival in consecutive years. In the lower Oder River, Germany, fish have been sampled annually, 0+ in July since 1997, and older fish in November since 1998. This data set was analysed to test the hypotheses mentioned above. The water temperature ranged between −0.4 and 25.1 °C during the study period, resulting in substantial variations of the 29 temperature metrics derived from daily means. Cumulative degree‐days until catch, in spring and during March, as well as minimum and mean temperatures in March and spring explained 63% of the variability observed. The mean total length of the most frequent 0+ fish differed significantly between years related to temperature. Increased length growth at higher temperatures was a general tendency. Total length and density of 0+ fish were significantly inversely correlated, but the potential influence of temperature on species densities was not significant. The mean fish densities varied not significantly between years. No indication was found that higher total length in the first year of life resulted in an improved growth in subsequent years.For future research and management it has to be expected that temperature impacts become increasingly significant in regulated river systems. With decreasing hydrodynamics the significance of temperature effects will increase.

ABSTRACT Consumer acceptability of three commercial scrambled egg patty formulations were evaluated before and after high pressure high temperature (HPHT) processing at 700 MPa/105C and 700 MPa/121C, and a selected formulation was also in‐pouch retort treated to an F0 of 5.6 min. A 40‐member consumer panel and a six‐member trained sensory panel (29 attributes judged) evaluated treated and untreated patties. Samples were also stored at 37C for 3 and 6 months for shelf‐life testing. Egg patty with added processed cheese was the most accepted formulation after treatment at 700 MPa/105C, maintaining most quality parameters after pressurization. Egg patty formulation with added xanthan gum gave similar acceptability scores at 700 MPa/105C and at 700 MPa/121C. After 6‐month incubation, HPHT‐treated products did not produce gas or decompose, while control patties degraded after 1 week storage at 37C. Thermal pressurization processing proved promising for the development of novel shelf‐stable egg‐based products.
Ultrastructure of the Malpighian Tubule Cells in the Mosquito Larvae, Anopheles sinesis
Authors: YU Chai Hyeock 
Published: March 2007

ABSTRACTUltrastructure of epithelial cells constituting the Malpighian tubule of Anopheles sinesis last instar larvae was observed with electron microscope. Malpighian tubule consists of four long and narrow tubule structures with principal cells in typical absorptive cells and regenerative cells forming the simple epithelium. Apical plasma membrane of the principal cell is differentiated into microvilli with one mitochondrion in each microvilli. Basal plasma membrane had extreme infolding to form a canaliculi and a well developed mitochondria was attached in the infoldings. And, rER, ribosomes, and vacuoles were well developed inside the cells. However, there were two main cell types depending on the differentiation of cell organelles. Type 1 cell was cubic, forming the distal portion of Malpighian tubule. The length of microvilli was approximately 4 μm and the basal infoldings were introjected to the depth of 2 μm inside the cell. On the other hand, Type II cell that formed the main proxinal portion was a low squamous type cells with shorter 2 μm of microvilli and the basal infoldings were introjected to the depths of 4 μm inside the cell. As for vacuoles scattered inside the cells, they were regularly observed in both Type I and II and the Type II cells had better developed cellular organelles. Although regenerative cells were extremely small, their cellular organelles were developed and their overall electron density was high that they appeared darker than the principal cells.

Published: March 2007

ABSTRACT Agrius convolvuli haemolymph ferritin was purified by KBr density gradient ultracentrifugation and anion exchange column chromatography. The 670 kDa ferritin was composed of two subunits of 26 kDa and 31 kDa. It was also shown that the protein had an isoelectric point (pI) of pH 7.4. The N‐terminal amino acid sequences of the two subunits were NH2‐DNXYQDVSLDXSQAXNXL (26 kDa subunit) and NH2‐TQXHVNPVNIQRDXVTMHXS (31 kDa subunit). The sequential analysis showed that they had high similarity to lepidopteran ferritin subunits, S‐ and G‐type, respectively. Using electron microscope, it was observed that the protein had a core whose size was about 7 nm. In the amino acid composition of the protein, Glu (13.22%), Asp (10.43%), Pro (9.69%), Leu (9.63%), Ala (9.55%) and Gly (8.49%) were in relatively high contents while Tyr (1.21%), His (2.58%) and Arg (3.10 %) were in low. It was shown that the amount of ferritin in A. convolvuli haemolymph was increased by injection of eight different heavy metal ions, FeCl3, HgCl2, CuSO4, ZnSO4, MnCl2, MgCl2, CrCl3 and CdCl2. Among the ions, Fe3+, Hg2+, Zn4+, Mn2+ and Cd.2+ significantly induced the amount of the protein.

Published: March 2007

ABSTRACTThe Gryllus bimaculatus ferritin was purified from the haemolymph by a consecutive four‐step procedures consisting of 50% ammonium sulfate fractionation, anion exchange column chromatography using HiTrapTM Q column (1.6 x 4 cm, Amersham Bioscience), 70°C heat treatment for 10 min, acid treatment of 0.1 M sodium acetate buffer (pH 6.0), and gel filtration column chromatography using G4000SW column (0.75 x 60 cm, Tosoh, Japan) connected on FPLC system. The purified ferritin was found to have two major subunits of 32 and 30 kDa and three minor subunits of 28, 27, and 25 kDa by 2D electrophoresis analysis. Amino acid composition analysis showed that there are high contents of Asp, Glu, Met, Leu, and Lys residues in ferritin while low contents of Cys, Tyr, and Trp residues in the protein. G. bimaculatus haemolymph ferritin could be classified as a methionine‐rich protein.

Authors: CHUNG Kyung‐Hwun , MOON Myung‐Jin 
Published: March 2007

ABSTRACTThe fine structure of the hemopoietic tissue and its detailed reticular organization in the mealworm beetle, T. molitor were examined using light and scanning electron microscopes. The major hemopoietic tissues in the abdomen were located on the upper surface of the dorsal diaphragm which continuous over the ventral wall of the heart. Histologic characteristics of this hemopoietic tissues are dense clusters of cells. They are irregular in outline and are not surrounded by any connective tissue sheath. The hemopoietic tissue of this insect is consisted of three cellular components which are the reticular cells, hemocytic stem cells and several kinds of mature hemocytes. The reticular cells had numerous cytoplasmic processes and forming a complex network. The stem cells give rise to differentiating hemocytes of the different cell lineages. Mature hemocytes within this hemopoietic tissue are originated from the stem cells and differentiated into several types of hemocytes including prohemocytes, plasmatocytes, and granulocytes.

ABSTRACTAdult mosquito surveillance was conducted during 2002 at 30 US military installations and training sites located in six provinces in the Republic of Korea (ROK). Adult mosquitoes were collected in New Jersey and dry ice ‐baited New Jersey light traps from 1 May through 15 October. Mosquito surveillance was conducted to determine threshold levels to initiate pesticide applications and identify malaria infection rates at selected Army installations and training sites. A total of 100,617 adults [82,410 (81.9%) females and 18,207 (18.1%) males] comprising 17 species and 7 genera were collected during 2002. The most common species collected were Culex tritaeniorhynchus Giles (49.5%), Anopheles sinensis Wiedemann (30.9%), Culex pipiens Coquillett(11.8%) and Aedes vexans nipponii (Theobald) (7.1%). Trap indices (TIs) varied widely for species over their range, due in part, to geographical distribution and degree of association with urban communities. Anopheles sinensis were collected at the same level while Culex tritaeniorhynchus increased by 27.2% in 2001, due in part to very high populations of Culex tritaeniorhynchus at Gunsan Air Base. The weekly population densities for some species were variable for each of the years, apparently as a result of variable annual weather conditions. None of Anopheles sp. assayed for plasmodium vivax (Pv) malaria infections by Enzyme Linked Immunosorbent Assay (ELISA) were positive.

Three‐Dimensional Reconstruction of Hematopoietic Organ of Bombyx mori Larva
Authors: JOO Kyoung Ook , MUN Ji Young , LEE Kyung Eun , YU Chai Hyeock , KANG Seok Woo , SEO Young Rok , HAN Sung Sik 
Published: March 2007

ABSTRACTThree‐dimensional reconstructions of a hematopoietic organ (HPO) from Bombyx mori larva were undertaken using light and electron microscopy. Each compact islet varied in sizes, but in the central area of the HPO their size became smaller. Compact islets and loose islets were made up of prohemocytes, plasmatocytes, and reticular cells, but there were differences in the proportions of these cells. Within the cytoplasm of reticular cells and within their cell projection, vacuoles were observed. Cell proliferation occurs primarily in the compact islets, and differentiation associated with the reticular cells occurs primarily in the loose islets. It can be inferred that reticular cells have a significant influence on proliferation and differentiation associated with hematopoiesis. According to the results of the 3‐D reconstruction, one reticular cell is in contact with eight or nine hemocytes. Each reticular cell is presumably of approximately ten hemocytes. Movies relevant to Figs. 3, 4 and 5 can be found at http://biotech.korea.ac.kr/ cellbio/pages/ 3D‐results.html.

ABSTRACT Orius strigicollis (Poppius) was reared on the modification of rearing media for Tetrastichus sp. at 28°C, 18L: 6D, and 50‐60% RH, in which meat diets were used for partial replacements of insect source of the artificial diets. Life history traits of the predacious bug fed on the diet were measured. Nymphal development period and mortality rate of O. strigicollis were about 14 days and 31.5% (survival rate: 68.5%), respectively. The female bug produced average of 82.5 eggs during its oviposition period of 18 days when artificial oviposition substrate was provided. The fecundity was shown to be superior compared with previous researches on the species fed natural preys as a food.

Laboratory Evaluation of the Lethal Efficacy of an Insect Growth Regulator, Pyriproxyfen against Anopheles sinensis (Diptera, Culicidae) Larvae
Authors: LEE Won‐Ja , LEE Dong‐Kyu 
Published: March 2007

ABSTRACTThe granular formulation of 0.5% pyriproxyfen is a mosquito insect growth regulator larvicide. It was evaluated for residual activity for killing and/or emergence inhibition against 3rd stage larvae of Anopheles sinensis in the laboratory. Mortality rates ranged from 60.9% to 79.7% at 0.01, 0.05 and 0.1 mg/L of water during the first seven days. Except for the lowest concentration (0.01 mg/L) mortality rates were greater than 80% from day 8 through 28. Mortality rates for 0.01 mg/L concentrations were 70.4% from days 8‐14, and thereafter exceeded 80% through day 28. The residual activity gradually increased post‐treatment since the granular formulation of pyriproxyfen has a gradual solubility and increases concentration of active ingredient over time. The mortality rates of An. sinensis larvae and pupae eventually reached 100% for the three (0.01, 0.05, 0.1 mg/L) concentrations.
Spinneret Microstructure of the Silk Spinning Apparatus in the Crab Spider, Misumenops tricuspidatus (Araneae: Thomisidae)
Authors: MOON Myung‐Jin , AN Jeong‐Su 
Published: March 2007

ABSTRACTThe silk spinning apparatus in the crab spider, Misumenops tricuspidatus was studied with the field emission scanning electron microscope (FESEM) and the main microstructural characteristics of the silk glands are presented. In spite of the fact that the crab spiders do not spin webs to trap a prey, they also have silk apparatus even though the functions are not fully defined. The crab spider, Misumenops tricuspidatus possesses only three types of silk glands which connected through the typical spinning tubes on the spinnerets. The spinning apparatus of Misumenops closely corresponds to that of wandering spiders such as jumping spiders or wolf spiders except some local variations. Anterior spinnerets comprise 2 pairs of the ampullates and 48 (±5) pairs of pyriform glands. Another 2 pairs of ampullate glands and nearly 20 (±3) pairs of aciniform glands were connected on the middle spinnerets. Additional 50 (±5) pairs of the aciniform glands were connected on the posterior spinnerets. The aggregate glands and the flagelliform glands which have the function of sticky capture thread production in orb‐web spiders as well as the tubuliform glands for cocoon production in females were not developed at both sexes of this spider, characteristically.

ABSTRACT

Ceftobiprole is a broad-spectrum cephalosporin with activity against methicillin-resistant
Staphylococcus aureus
(MRSA) that is undergoing phase III trials for the treatment of complicated skin and skin structure infections and nosocomial pneumonia. The objectives were to describe the pharmacodynamic profiles of ceftobiprole given at 500 mg intravenously (i.v.) every 8 h (q8h) (2-h infusion) and 500 mg i.v. every 12 h (q12h) (1-h infusion) to determine the overall probability of target attainment (PTA) by weighting for the expected distributions of renal function in the populations of interests, to determine the PTA against representative pathogens encountered in clinical trials, and to determine the optimal renal dose adjustment for ceftobiprole at 500 mg i.v. q8h (2-h infusion). Data for a total of 150 subjects in phase I/II trials were analyzed by using the population pharmacokinetic modeling program BigNPOD (nonparametric optimal design). Monte Carlo simulation was performed with the ADAPT II program to estimate the PTA at which the free drug concentrations exceed the MIC for 30 to 60% of the dosing interval (30 to 60%
fT
> MIC). For ceftobiprole at 500 mg i.v. q12h, the probabilities of achieving 30% and 50%
fT
> MIC exceeded 90% for MICs ≤2 mg/liter and ≤1 mg/liter, respectively, For ceftobiprole at 500 mg i.v. q8h, the probabilities of achieving 40 and 60%
fT
> MIC exceeded 90% for MICs ≤4 mg/liter and ≤2 mg/liter, respectively. For ceftobiprole at both 500 mg i.v. q12h and 500 mg i.v. q8h, the probability of achieving a nearly bactericidal effect (50%
fT
> MIC) exceeded 90% for methicillin-susceptible
S. aureus
and MRSA. For gram-negative pathogens, the PTA for achieving a nearly maximal bactericidal effect (60%
fT
> MIC) for ceftobiprole at 500 mg i.v. q8h exceeded 90% for non-AmpC-producing gram-negative organisms. Ceftobiprole at 500 mg i.v. q12h, for patients who had a creatinine clearance rate of ≤50 ml/min, was identified as the most appropriate treatment regimen for patients who require renal dose adjustment for mild to moderate renal impairment.
AUTOMORPHIC EQUIVALENCE PROBLEM FOR FREE ASSOCIATIVE ALGEBRAS OF RANK TWO
Authors: DRENSKY VESSELIN , YU JIE-TAI 
Published: March 2007

Let K 〈x,y〉 be the free associative algebra of rank 2 over an algebraically closed constructive field of any characteristic. We present an algorithm which decides whether or not two elements in K 〈x,y〉 are equivalent under an automorphism of K 〈x,y〉. A modification of our algorithm solves the problem whether or not an element in K 〈x,y〉 is a semiinvariant of a nontrivial automorphism. In particular, it determines whether or not the element has a nontrivial stabilizer in Aut K 〈x,y〉. An algorithm for equivalence of polynomials under automorphisms of ℂ[x,y] was presented by Wightwick. Another, much simpler algorithm for automorphic equivalence of two polynomials in K[x,y] for any algebraically closed constructive field K was given by Makar-Limanov, Shpilrain, and Yu. In our approach we combine an idea of the latter three authors with an idea from the unpublished thesis of Lane used to describe automorphisms which stabilize elements of K 〈x,y〉. This also allows us to give a simple proof of the corresponding result for K[x,y] obtained by Makar-Limanov, Shpilrain, and Yu.
