The DNA and protein content of atrial cardiomyocytes and the size and ultrastructure of the cardiomyocytes in children with congenital heart defects

: Right atrium myocytes were obtained during open heart surgery from 4 patients with atrial septal defect, and from 1 patient with Fallot's tetrad, aged from 3.5 to 6 years. DNA and total protein contents were measured consecutively in isolated cells using two-wave-length scanning cytophotometry following double staining after Feulgen and with naphthol yellow S. All the biopsies contained polyploid myocytes: the number of 4c cells varied from 18 to 41%, that of 8c cells from 0 to 4%. The average values of cells area and protein content for tetraploid cells were 1.5 times higher that for diploid ones. In all the cases normal and little changed myocytes were dominating (69-91%). The highest number of cells with moderate and severe degenerative changes was registered in the cases of maximum degree of cell hypertrophy and polyploidization.
Towards Developing a Pro-Entrepreneurship Internship Program: An Appraisal of Southern University Model

The main purpose of this research is to identify the problems of traditional internship programs conducted at tertiary level educational institutions and propose a practical model of the internship entrepreneurship program. The qualitative research method has been used here to explore the existing problems of traditional internship programs, and rationalize the necessity of entrepreneurship internship program of Southern University Bangladesh (SUB)as an alternative to the traditional internship program. In this regard, three focused group discussions were conducted with three main stakeholders, namely the faculty guide, the internship supervisors of the host company, and the student interns. The study discovered different weaknesses of traditional internship programs conducted in the university, including the limited scope of internship, noncooperation by the host companies, and the limitation of time. However, all the stakeholders are on the same page regarding the incapacity of traditional internship programs in developing the entrepreneurial spirit and aspiration among the interns. The study proposed the SUB model as an independent way to conduct an entrepreneurship-friendly internship program at tertiary level education, which may help the concerned to overcome the challenges of a traditional internship program. This research may contribute to the body of knowledge of higher education management and may support academia to develop an entrepreneurship development centered curriculum.
Hematopoietic stem cell transplantation

The purpose of regenerative medicine [6], especially tissue engineering, is to replace damaged tissue with new tissue that will allow the body to resume normal function. The uniqueness of tissue engineering is that it can restore normal structure in addition to repairing tissue function, and is often accomplished using stem cells [7]. The first type of tissue engineering using stem cells [7] was hematopoietic stem cell transplantation (HSCT), a surgical procedure in which hematopoietic stem cells [8] (HSCs) are infused into a host to treat a variety of blood diseases, cancers, and immunodeficiencies. While there is a standard procedure for the infusion of these cells into a donor, variations in the sources of hematopoietic stem cells [8], and in the relationship between donor and recipient, do produce some variability in the procedure.
Growth rates and ecology of coralline rhodoliths from the Ras Ghamila back reef lagoon, Red Sea

Rhodoliths are important marine carbonate producers that provide habitat for several marine organisms, and are threatened by ongoing global climate change. Meter-sized sedimentary patches rich in living rhodoliths, interspersed among corals, were discovered in the back reef of Ras Ghamila lagoon, Southern Sinai, at less than 1 m water depth. In this shallow and relatively sheltered subtropical environment, rhodoliths were found to be monospecific or oligospecific, spheroidal, 3.5 to 9.4 cm in maximum diameter, with warty/lumpy or fruticose (protuberance degree IV) growth forms, and corresponded to the unattached branches or praline type. They grew in bright light under seasonal, moderate, wind-driven water motion. The dominant rhodolith-forming species recorded were: Lithophyllum kotschyanum, Porolithon onkodes, Hydrolithon sp. and three species of Neogoniolithon: Neogoniolithon fosliei, Neogoniolithon brassica-florida, and an undescribed species noted in the text as Neogoniolithon sp. A total of 38 Alizarin-stained rhodoliths was released in the field and collected after 1 year. They showed different banding patterns (alternating long and short cells) that revealed seasonal growth, with the lowest rates occurring in winter for all species, and an additional summer growth slackening in Neogoniolithon fosliei. Lithophyllum kotschyanum presented evidence of occasional growth cessation, possibly due to temporary burial. The observed annual growth rate of rhodoliths was unrelated to their size. The mean accretion rates were 1.08 mm · year−1 in L. kotschyanum, 0.75 mm · year−1 in P. onkodes, 0.49 mm · year−1 in Hydrolithon sp. , 0.85 mm mm · year−1 in N. fosliei, 0.63 mm · year−1 in N. brassica-florida and 0.57 mm · year−1 in Neogoniolithon sp. The annual mean marginal elongation rate for these taxa was respectively 8.74, 13.92, 3.59, 9.40 and 9.25 mm · year−1, with the exception of Neogoniolithon sp. , for which this parameter was not recorded. Maximum marginal elongation occurred in P. onkodes pointing out its greater ability as a space competitor in comparison with the other rhodolith species. The highest accretion rate and common presence of L. kotschyanum indicate its importance as carbonate producer in tropical reef.
Állatcsontok a Teleki Palota törökkori gödréböl

The site's composition of the animal bones material is very characteristic of the Turkish era. The animals that were considered unclean (dogs and especially pigs) are rather few in number, and there are many cats, an animal well liked by Turks. The proportion between the most important animals (sheep/goats, poultry and cattle) shows that sheep and goat occured more frequently and also there was a large number of poultry. The cattle seem to take the third place in the prder of importance. But there is no need to seek a general explanation for this sequence: it can well be that it only explains the habits of people living in this particular area.
Antioxidant Potential and Phenolic Compounds of Brown Seaweeds Turbinaria conoides and Turbinaria ornata (Class: Phaeophyceae)

ABSTRACT Antioxidant potential, total phenolic content, and high performance liquid chromatography-based solvent extract fingerprints of phenolic constituents of brown seaweeds, Turbinaria conoides and Turbinaria ornata, were evaluated. The ethyl acetate (EtOAc) fraction of the seaweeds registered greater phenolic content and antioxidant activities. Salicylic acid, gallic acid, quercetin, and syringic acid were predominant in the EtOAc fraction of T. conoides, while the main components in EtOAc fraction of T. ornata were quercetin and salicylic acid. This study demonstrated the candidacy of Turbinaria spp. as a potential source of antioxidant phenolics for use as food supplements and nutraceuticals to deter deleterious free radical-induced disorders and diseases.
Preliminary Studies of Food Habits of

During the year 1978, juvenile salmonids were collected from coastal streams run- ning through China Poot Marsh and the stomach contents analyzed. Stomach contents of threespine stickleback (Gasterosteus aculeatus) and staghorn sculpin (Leptocottus armatus) from China Poot and of threespine stickleback from Potter Marsh were also analyzed; these two species were generally caught in tidal pools on the marshes. The juvenile coho salmon (Oncorhynchus kisutch) had the most varied diet; 37 different prey items were identified in the stomachs. By comparison, 25, 26, and 33 prey taxa were identified in the stomach contents of Dolly Varden char (Salvelinus malma), threespine stickleback, and staghorn sculpin, respectively. Amphipods were the dominant prey of all fish collected from China Poot Marsh; chironomidae larvae were the most common item in the stomach contents of threespine stickleback from Potter Marsh. The diets of all species changed over the course of the study period; the change was most dramatic for juvenile salmonids and sculpins.
NON-LOCAL FINITE STRAIN ELASTICITY MODELS FOR TRUSSES

The present work addresses the study of strain localization phenomena in hyperelastic media undergoing finite deformation. In this context, localization is a consequence of geometric instabilities. A regularization technique, called non-local integral, is used to restore the well-posedness of the boundary value problem and to eliminate spurious mesh dependence of the numerical results. In the non-local model here proposed for truss structures, the strain at a point is assumed to depend on weighted average of the stretch over a certain neighborhood, and not only on its local value. Numerical implications of this choice are considered. The effectiveness of proposed model in finite element analysis is tested with reference to a bar under quasi-static loading.
Laboratory confirmation of an outbreak of Clostridium perfringens food poisoning.

: A foodborne outbreak in a group of eleven individuals sharing a common meal, eight of whom reported symptoms and an incubation period compatible with Clostridium perfringens food poisoning, was confirmed by the following laboratory criteria: (a) the C. perfringens count in the suspect food, chicken pie, was at least 10(5) per gram; (b) the median fecal C. perfringens spore count in convalescing patients was greater than 10(6) per gram: (c) an indentical serotype (PS63) was isolated from both the food and fecal specimens; and (d) the C. perfringens isolates from most of the patients (8 out of 10) were of the same serotype. The results confirm the usefulness of fecal spore counts and serotyping in implicating C perfringens in food poisoning outbreaks.
RELAÇÕES TOPOGRÁFICAS DOS SACOS AÉREOS DE CODORNAS (Coturnix coturnix)

The morphology of birds is rarely reported, hindering veterinary practice in these animals. The respiratory system is distinguished by the presence of air bags, a structure of fundamental importance to the birds, but very susceptible to diseases. Thus, the objective of this study was to describe the anatomy of the air sacs (AS) in quails regarding their topographical relationships. To this, fifteen quails that had their respiratory tract injected with Neoprene, stained and fixed in formalin 10% latex were dissected. Cervical AS is unique and has a middle portion located between the brachiocephalic arteries. The clavicular AS is also odd and starts near the first thoracic vertebrae. The cranial and caudal thoracic AS are lateral to the lung and medially to the ribs. The cranial thoracic AS goes from the dorsal lateral-cranial margin to the ventral margin of the liver, and the caudal thoracic AS goes from the fourth lateral-caudal margin of the liver to the cranial third of the abdominal AS. Abdominal AS goes from the liver to the base of the vent area. However, the air sacs in quails studied in this research follow a topographic pattern, forming diverticula between adjacent organs.
Glycoproteins in daphnids : potential signals for mating ?

Glycoproteins are used as mating signals by several aquatic organisms. We have developed techniques for selectively probing surface glycoproteins in zooplankters using fluorescently labeled lectins. We used these techniques to localize glycoproteins that could be used in cladoceran mating. Daphnia obtusa and Ceriodaphnia dubia females were screened for 12 lectins representing a wide variety of carbohydrate affinities. The structure exhibiting fluorescence in both species was the ovary. The signal contrast (signal/background ratio) across the ovary ranged from 2 to 21 which seems sufficient for males to discriminate a glycoprotein signal from noise. Results indicate that several glycoproteins which might be important in mating are present in the ovary of both species.
The predaceous fly Lispe candicans (Diptera: Muscidae) and its chemically protected prey, the rove beetle Bledius furcatus (Coleoptera: Staphylinidae)

Lispe candicans Kowarz 1892 is a predator of the rove beetle Bledius furcatus (Olivier 1812) (Staphylinidae : Oxytelinae). In encounters, the fly attempts to pierce the beetle and suck it out by using its proboscis. The proboscis is adapted for this purpose by strong prestomal teeth, which can produce large holes in the beetle's integument. B. furcatus defends itself with an abdominal defensive gland, although in 23% of the encounters observed individuals of B. furcatus were killed. In the course of the mating of L. candicans the M presents a characteristic courtship behaviour. During egglaying the F is accompanied by a M.
Apolipoprotein B100 and some lipid components during transition period in cows under hot and thermoneutral environmental conditions.

Study conducted to investigate the biochemical changes in the blood (apolipoprotein B100 and some lipid components) of crossbred cows (Brown Swiss × Baladi) during the transition period under hot and thermoneutral environments. Twelve cows were divided in to two equal groups; hot and thermoneutral environment. Blood samples were collected and ApoB100, total protein, glucose, cholesterol, triglycerides, non-esterified fatty acid (NEFA), β-hydroxybutyric acid (BHBA), and thyroid hormones (T 3 and T 4 ) were estimated. Temperature-humidity index as well as milk yield and composition were also recorded in each season. The levels of almost all of studied parameters including ApoB100, total protein, cholesterol, triglycerides, glucose, and thyroid hormones detected in the thermoneutral group significantly exceeded those detected in the other group (hot environment). On the other hand, the levels of NEFA and BHBA detected in the blood of the cows in the hot environment group significantly increased than those of the thermoneutral group. In addition, the blood contents of the two lipid components (NEFA and BHBA) were negatively correlated with the level of ApoB100. Milk yield and composition were also among the parameters affected negatively by heat stress, and were positively correlated with the level of ApoB100 postpartum. The studied parameters may present a valuable assess for the prediction of the disturbance during this critical period.

La biologie, jusqu'a present condamnee a etre une science descriptive, devient une science predictive. La possibilite pour le biologiste de modeliser le vivant, et probablement de construire dans un proche avenir des theories du vivant, n'est pas sans consequence dans le domaine de la sante et dans la bataille contre le cancer.
Clipping of Water-stressed Blue Grama Affects Proline Accumulation and Productivity

Water-stressed plants accumulate abnormally large amounts of free proline, a protein component. Blue grama (Boutelouagracilis) was clipped and water-stressed to test whether the degree of proline accumulation might be related to regrowth potential of . range grass. Clipping of plants before stress reduced the accumulation of proline in bases of stressed shoots but increased herbage production; clipping after stress speeded the decrease of accumulated proline in shoot bases.
A Novel Eco-friendly Method of Using Red Algae (Laurencia papillosa) toSynthesize Gold Nanoprisms

This is the first report on a rapid green synthesis of gold nanoparticles (GNPs) using red algae (Laurencia papillosa). The green synthesis of eco-friendly nanoparticles is of a great interest in nanoscience for biomedical applications and specifically for clinical diagnostic applications. GNPs especially nanoprism represents a new advanced tool to study cell function and useful in optoelectronics, in developing a drug delivery system to control plant virus diseases and in nanomedicine. Conventional physical and chemical methods have been developed for the synthesis of metal nanoparticles, but these methods are expensive and require the use of toxic and aggressive chemicals. In this paper, it is demonstrated that a rapid, low coast and eco-friendly method for synthesis of gold nanospheres and its conversion into gold nanoprisms has been developed. The method involves using water solvent extract of L. papillosa as a reducing agent. Nanoscopy and computational analysis revealed that the nanoprism and other different morphologies were obtained just by varying the concentration molarity of tetrachloauric acid (HAuCl4), keeping the concentration of pure algal extract (PAE) constant. In the same time, we perform ImageJ analyses for the size distribution of TEM images. The best concentration of AuCl4 was 5 mM and best concentration of the red algae extract was at 0.05 g/ml. The functional groups responsible for conversion of nanosphere into nanoprism were NH and OH groups found in the contents of the red algae extract. The as-synthesized gold nanoprisms were characterized by several physicochemical techniques. The nanoprisms are single crystalline, whose basal plates surface are atomically flat "111" planes. We anticipate our results to be a starting point for more applications in medicine, plant virus diseases, and industrial technology.
Heritability estimate of seed germination parameters in Pinus leucodermis Antoine

Seeds of palebark Heildrich pine (Pinus leucodermis) were collected from five populations located at different altitudes on Monte La Spina (Lat. 40°07'N; Long. 15°56'E) and Monte Pollino (Lat. 39°54'N; Long. 16°11'E) (Italy). A statistically-significant inverse relationship between germination percent and mean germination time with altitude has been found. High values for the narrow sense of heritability relative to these germination parameters were obtained, reflecting the primary role of genetic influences on conifer seed germination.

Analysis of Genetic Translation using Signal Processing

PONNALA, LALIT Analysis of Genetic Translation using Signal Processing. (Under the direction of Dr. D. L. Bitzer, Dr. M. A. Vouk and Dr. A. Stomp). A series of free energy estimates can be calculated from the ribosome’s progressive interaction with mRNA sequences during the process of translation elongation in eubacteria. A sinusoidal pattern of roughly constant phase has been detected in these free energy signals. Frameshifts of the +1 type occur when the ribosome skips an mRNA base in the 5’-3’ direction, and can be associated with local phase-shifts in the free energy signal. We propose a mathematical model that captures the mechanism of frameshift based on the information content of the signal parameters and the relative abundance of tRNA in the bacterial cell. The model shows how translational speed can modulate translational accuracy to accomplish programmed +1 frameshifts and could have implications for the regulation of translational efficiency. Results are presented using experimentally verified frameshift genes across eubacteria.

Reversibility of pH-induced changes in the calcium distribution and melting characteristics of mozzarella cheese

Reversibility of pH-induced changes in the calcium distribution and melting characteristics of mozzarella cheese Previous studies that used a post-manufacture method to increase or decrease the pH of mozzarella cheese demonstrated that cheese melting characteristics and calcium distribution are profoundly influenced by pH. The study objective was to evaluate whether these pH-induced changes are reversible. Two experiments were conducted. In the first, representative shredded samples of cultured low-moisture part-skim mozzarella cheese were exposed to acetic acid vapour to decrease the pH by ca. 0.6 pH units in three increments. After equilibration at 4°C for 24 h, the samples were analysed for apparent viscosity and water-soluble calcium. The sample with the lowest pH was divided into representative subsamples and exposed to ammonia to increase the pH by ca. 0.6 pH units in three increments. After equilibration at 4°C for 24 h, the subsamples were analysed for apparent viscosity and water-soluble calcium. This experiment was replicated three times with different batches of cheese. Decreasing the cheese pH from ca. 5.3 to 4.8 resulted in nonlinear (quadratic) increases in apparent viscosity and water-soluble calcium, and cheeses lost the ability to melt and stretch below pH 5.0. Upon reversal of cheese pH back to ca. 5.1, apparent viscosity and water-soluble calcium decreased in nonlinear (quadratic) manner and cheeses regained the ability to melt and stretch. The design of the second experiment was similar to that of the first, except that the pH was first increased in three increments to ca. pH 6.6 and then decreased. Increasing the cheese pH from ca. 5.2 to 6.6 resulted in a linear increase in apparent viscosity and a more fibrous and elastic melted consistency. Upon reversal of cheese pH back to ca. 5.2, apparent viscosity decreased in a linear manner, showing a high degree of reversibility. Water-soluble calcium showed a linear decrease with increasing pH, and then increased in like manner when the pH was reversed. Results suggest that the reversible association and dissociation of calcium from the casein matrix contributed to structural changes that were responsible for the observed reversible pH-induced changes in melted consistency. La distribution du calcium et les caracteristiques de fusion de la mozzarella sont tres influencees par le pH. Cette etude evalue si les changements induits par le pH sont reversibles. Les resultats suggerent que l'association et la dissociation reversibles du calcium de la matrice de caseine contribuent aux modifications structurales qui sont responsables des changements induits par le pH dans la fusion de la mozarella.
Antioxidative Stress Peptides

Oxidative stress is a state characterized by an excess of reactive oxygen species (ROS) in the body, which creates a potentially unstable cellular environment linked to tissue damage, degenerative disease, and accelerated aging. Many environmental factors are implicated in the generation of ROS. Specific dietary antioxidants have been considered to modulate oxidative stress and suppress gut inflammation and carcinogenesis. Recently, we have developed phosphopeptides (PPPs) from hen egg yolk phosvitin and found PPPs act as inhibitors of lipid peroxidation and radical scavengers. In the present study, the protective effects of PPPs against hydrogen peroxide (H 2 O 2 )-induced oxidative stress in an in vitro assay was evaluated using human intestinal epithelial cells, Caco-2. The effects of PPPs on intracellular glutathione (GSH) levels and several antioxidative enzymes were also investigated. The results suggest that PPPs could suppress oxidative stress-induced gut inflammatory disorders and may potentially provide new bioactive peptides against tissue oxidative stress.
