The relationship of oxidative stress parameters with infarct volume and National Institutes of Health Stroke Scale in ischemic stroke / İskemik inmede oksidatif stres parametrelerinin infarkt volümü ve National Institutes of Health Stroke Scale ile ilişkisi

Abstract Objective: What we know about the relationship between oxidative stress parameters and ischemic stroke is still limited and controversial. Our study aimed to investigate the relationships among ischemic lesion volume, National Institutes of Health Stroke Scale (NIHSS) values, and oxidant and antioxidant levels to determine whether oxidative stress paramaters is effective on stroke severity in ischemic stroke patients. Methods: The study included 34 patients with ischemic stroke and 34 volunteers with no active diseases. Total Oxidant Status (TOS), Total Antioxidant Status (TAS), thiol, paraoxonase, stimulated paraoxonase (stparaoxonase) and arylesterase were measured in blood samples collected on admission from patients diagnosed with ischemic stroke. The Oxidative Stress Index (OSI) was calculated. The same oxidative stress parameters were measured in the control group and compared with the patient group. Correlation between the oxidative stress parameters, the infarct volume and the NIHSS was studied. NIHSS was calculated when patients were admitted to the emergency department. The infarct volume was calculated using diffusion-weighted magnetic resonance imaging performed in the first 72-96 hours. Results: TOS and OSI values were significantly higher in the case group than the control group. Paraoxonase, arylesterase, and thiol values were significantly lower in the case group than the control group. TAS and stparaoxonase values weren’t differed significantly between the case and control groups. There were significant negative correlations between the NIHSS value and both the paraoxonase value and stparaoxonase value. There were no significant correlations between the NIHSS value and the infarct volume and the TAS, TOS, OSI, arylesterase, and thiol values. Conclusion: We concluded that change in oxidative stress balance in favor of oxidants could be a cause in the pathogenesis of ischemic stroke but oxidative stress alone can’t be sufficient in predicting the severity of stroke.
Rapid Estimation of Microbial Numbers on Meat and Poultry by the Direct Epifluorescent Filter Technique.

The direct epifluorescent filter technique (DEFT) for rapid estimation of microbial numbers was evaluated by comparison with the plate count on a variety of uncooked red meat and poultry samples. Good agreement [correlation coefficient (r) = 0.95-0.96] was obtained from samples with plate counts of 5 × 103/g or /cm2 and above from red meat carcasses (surface swabbed), aerobic or vacuum packed chill-stored joints (surface sampled - stomachered) and frozen beef (thawed stomachered). For stored and unstored raw poultry sampled by skin scraping or stomachering of muscle and skin good overall correlation (r = 0.88-0.89) was obtained between the DEFT count and the plate count in the ranges 1.1 × 103 to 1.3 × 107/cm2 (skin scraping) and 1 × 104 to 9.5 × 106/g (muscle and skin) even though the DEFT always overestimated counts on samples on which no growth had occurred (plate count <7×104/cm2 or <1×105/g). However, good linearity between DEFT and plate counts allowed use of the regression equation to obtain a good estimate of the plate count on these samples. The DEFT was unsuitable for application to poultry neck skin sampled by shaking because particulate material interfered with counting. This was also a problem with Mechanically Recovered Meat although the DEFT gave a fair estimate (r = 0.72) of the plate count on certain types (beef and veal) of this product. The DEFT was capable of providing counts within 35 to 45 min and its applicability to the rapid estimation of bacterial numbers in meat and poultry is discussed.
The rediscovery of the liverworts Anastrophyllum donnianum and A. saxicola in Central Europe (Slovakia, Tatra Mountains)

In 2006-2008, I found new localities of Anastrophyllum donnianum and A. saxicola in the Slovakian Tatras (Western Carpathians). These liverwort species had not been reported from Slovakia since 1888, and were classified as extinct. Both are found in this part of Europe in isolated localities in mountains, at the southern limit of their European distribution. Anastrophyllum donnianum is rare in Europe.
Efficiency and Health Hazards Tests on Vapona Used in Insect Collections

The application o f Vapona a s a fumigant i n insect collections was tested t o replace the traditional paradichlorobenzene in the Transvaal Museum. In a number of tests the op­ timal quantity of Vapona was found to be 1 / 1 0 of a commercial strip (± 20 x 30 mm) applied in a collection drawer of about 3 5 x 45 x 6 cm . An application regime was worked out by transferring the Vapona pieces weekly into new groups of collection drawers , com­ pleting a fumigation cycle in 1 2 weeks. The Dichlorvos concentration in the air was tested on the body of the operator and in the room during various phases of the treatment . I t was found that the measured concentration at no time exceeded 1 5 % of the Threshold Limit Value (TLV-TWA see Conclusions) on the body of the most exposed person and 2 % of the TL V -TWA in the room.
Reoperations After Cataract Surgery: Is the Incidence Predictable Through a Risk Factor Stratification System?

Introduction The objective of the study was to quantify the number of procedures needed to achieve the best possible surgical outcome, depending on the number and type of risk factors identified. Methods Two independent observers reviewed the medical records of 1,502 patients who underwent phacoemulsification surgery, during a two-year period (January 1, 2014 to December 31, 2015). Preoperative risk factors were documented according to the stratification system used. Based on the total risk score, each case was allocated to one of four risk groups with 0, 1-2, 3-5, and >6 total risk factors, respectively. All qualitative and quantitative characteristics were gathered and included in a multivariate analysis. Results A total of 1,792 eyes were included. Αge over 88 years, low cooperation ability with the patient, and surgeries performed by residents tended to have more often complications, while white/intumescent cataract, iridodonesis/phacodonesis, α1 blockers intake, and male gender are risk factors positively associated with more than one surgery. Conclusions Risk factors tend to be prognostic for possible intraoperative complications. The number of procedures needed for the best possible surgical outcome seems to depend on these preoperative risk factors. A stratification method increases the level of awareness of the surgeon, and therefore may decrease the number of complications and even procedures while enhancing the "safe" practice and skills of residents.
Significance of fruit and vegetable allergens: Possibilities of its reduction through processing

ABSTRACT Fruit and vegetable allergies are prevalent commonly in adults, infants, and children all around the world, but more importantly in Europe and North America. The only solution is complete abstinence from the responsible food, which can be very difficult due to their presence in the form of hidden or undeclared ingredients. Various studies have shown the direct effect of processing on the secondary structure of proteins that can mitigate the allergic properties. The impact of these processing techniques on fruit and vegetable allergies have shown limited success due to the fact that they have multiple allergens that are especially heat stable. Apples, kiwi, peach, and melons are common fruits, whereas celery and carrot are the common vegetables that can result in allergic reactions for some portion of the population upon exposure.

Ultrasound Role in Management of Female Infertility

Background: Investigation of the probable causes of female infertility is complex and in many instances a complicated process. Aim of Study: To discuss the role of ultrasound in detection of causes of female infertility (including those disorders of cervix, ovaries, fallopian tube and uterus) illustrated by few cases. Patients and Methods: This cross sectional study was conducted on thirty female patients seeking fertility at Itay scan private radiology center, Itay Elbaroud and Al Dlangat General Hospitals, during the period from January 2018 to January 2020. All patients were subjected to examination using (GE healthcare Voluson P8 and Toshiba Nemio 30 and Medison Sono Ace R3) Ultrasound Machines. Results: Uterine abnormalities represent about 60%, cervical abnormalities represent 3.3% and ovarian abnormalities represent 23.3%, while tubal abnormalities represent 13.3% of the study group. Mean age of uterine abnormalities is about 30.5 years old, cervical abnormalities about 26 years old, ovarian abnormalities about 26 years old while mean age of tubal abnormalities is 30.5 years old in the study group. In most cases of female infertility in our study, ultrasound has been of great value: e.g. uterine malformations (sub septate and bicornuate uterus), endometrial abnormalities (endometrial polyp and focal endometrial hyperplasia), myometrial diseases (fibroids and uterine adenomyosis), tubal abnormalities (including hydrosalpinx and endometriosis), ovarian functional abnormalities (polycystic ovary) and cervical abnormalities (cervical masses). Conclusion: Ultrasound is a reliable tool in the diagnosis of many anatomical causes of female infertility and is comparable to gold standard investigations in many circumstances, so we recommend it as primary investigation modality that could be complemented by other tools e.g. MRI, HSG, and laparoscopy when needed.
Dilute-acid Hydrolysis of Cellulose to Glucose from Sugarcane Bagasse

As the main component of lignocelluloses materials, cellulose is a biopolymer consisting of many glucose units connected through β-1,4-glycosidic bonds. The breakage of the β-1,4-glycosidic bonds by acids leads to the hydrolysis of cellulose polymers, resulting in the sugar molecule glucose or oligosaccharides. Mineral acids, such as HCl and H2SO4, have been used in the hydrolysis of cellulose. The lignocellulosic materials usually require a first step of pretreatment due to the association between the three major components of plant cell wall (cellulose and hemicelluloses fractions and lignin) in order to make available the monomeric sugars found in these fractions, for fermentation to ethanol. Different procedures have been employed, for example, acid hydrolysis, alkali hydrolysis, steam explosion, among others. The pretreatment using dilute sulfuric acid (acid hydrolysis) is the most widely used for having high efficiency in the separating process of cell wall components resulting in hemicellulose hydrolysate and cellulignin. A second step for obtaining the cellulose present in the cellulignin, studies have shown a need for delignification stage using sodium hydroxide as catalyst. The cellulose is submitted to acid or enzymatic hydrolysis to solubilize the glucose (cellulose hydrolyzate). Regardless of intense research on cellulose hydrolysis process by enzymatic way, the amount of hydrolyzate obtained in this process is still less than the amount required for subsequent studies on the fermentation of these hydrolysates which opens the option of research for the use of chemical hydrolysis. In order to use sugarcane bagasse as a substrate for ethanol production, optimum conditions for acid hydrolysis of cellulose fraction were investigated. A 23 full factorial Central Composite Design (CCD), including three replications at the center point was applied to evaluate the effect of temperature, acid concentration and reaction time on extraction efficiency. In this study, the hydrolysis of cellulose conditions varied in terms of sulfuric acid (H2SO4) concentration (2-6 %, w/v), reaction time (10-30 min) and incubation temperature (155-175 oC). The experiments were carried out using a 200-ml stainless-steel container (19 x 7 cm), which was tightly sealed and immersed in a silicone bath provided with electrical heating. The maximum extraction efficiency (E) was 71 % under the conditions of 2 % of H2SO4 at 155 oC for 10 min, which the main components (in g L-1) in the hydrolysate were glucose, 22.74; 5-hydroxymethylfurfural, 0.206; furfural, 0.145 and no xylose, arabinose and acetic acid formation was detected. Experiments will be performed to evaluate the fermentability of this hydrolysate to ethanol by Scheffersomyces stipitis.
VARIATION OF NITROGEN AND CARBOHYDRATE CONSTITUENTS DURING THE DEVELOPMENT OF HIMANTHALIA ELONGATA (L.) S. F. GRAY

1. Monthly variations in chemical constituents have been followed throughout the development of Himanthalia elongata.2. Nitrogen, laminarin, mannitol, alginic acid and fucoidin increase during the first year's growth of the vegetative button.3. Associated with receptacle initiation, the carbohydrate and nitrogen reserve of the button is utilized and there is a synthesis of protein from the non-protein constituents.4. The young receptacles build up a reserve of non-protein materials which are later utilized in protein synthesis during the formation of the gametes.5. It was concluded that during the life history of Himanthalia elongata from germination to maturity and senescence, separate parts of the plant undergo their own ontogenetic changes which are correlated with changes in the chemical composition.

Habitat dependent nurse effects of the dwarf-shrub Dryas octopetala on alpine and arctic plant community structure1

Abstract: Some species may increase community diversity by modifying the local environment for co-occurring species. This is most common in habitats of high abiotic stress. To explore whether the mat-forming dwarf shrub Dryas octopetala functions as a nurse plant in alpine and arctic plant communities of contrasting but generally stressful environmental conditions, we measured species diversity, richness, cover, and composition of different functional groups (vascular plants, bryophytes, and lichens) inside and outside Dryas mats at sites differing in environmental severity at Finse, alpine Norway, and in arctic Svalbard. Dryas appears to function as a nurse plant primarily for bryophytes, and mainly at the most severe sites in Svalbard. At the more benign sites at Finse, total diversity (Shannon’s index) and richness, and richness of all functional groups, were lower inside Dryas than outside, suggesting that Dryas has no nurse plant function on diversity parameters there. Species composition, however, differed inside and outside Dryas in all the communities, due to both presence/absence and abundance differences at Finse, and primarily due to differences in species abundances in Svalbard. This may suggest that Dryas functions as a nurse plant for individual species of all of the three functional groups in all the communities, even if competitive impacts of Dryas may overrule the positive effects on a whole-community level. Finally, our results show that Dryas may shift from being a nurse plant to being a competitor when its cover increases, but only under relatively low abiotic stress.
Over-expression of Gene FaASR Promotes Strawberry Fruit Coloring

Abstract Fruit development and ripening is a complicate process. Although much progress has been made on the ripenig process, the molecular mechamism of fruit development is not yet clear. In this study, we used ‘Sweet Charlie’ strawberry as test materials, based on cloning the strawberries ASR homologous gene, we carried out the bioinformatics and temporal expression analysis of FaASR , by manipulating ASR gene expression level in strawberry fruit, we tested the changes of physiological indicators, including sugar, ABA, pigments content, and fruit firmness, as well as phenotypic changes. In addition, we measured the expression changes of some anthocyanin-related gene, such as CHS and UFGT , by which we revealed the regulation mechanisms of ASR gene over strawberry fruit ripening. Strawberry ASR contained a typical domain of ABA/WDS that was related to fruit ripening and stress-resistance, and ASR gene over-expression could promote strawberry fruit coloring, endogenous ABA and sucrose accumulation, fruit softening, and induced the transcription levels of anthocyanin-related genes CHS and UFGT . The present study will further reveal the molecular mechanisms of information transmission in fruit development, and will also play an important foundation for future molecular improvement of strawberries breeding.

Insight into Disease Processes through Studies of the Intracellular Vesicle Transport System

Eukaryotic cells synthesize different types of molecules that are transported within the cell to discrete areas, or secreted outside of the cell, in small packages, called vesicles. The mechanism by which intracellular vesicles carrying distinct cargo molecules are delivered to specific cellular compartments, and the means by which vesicles fuse with specific organelles or the plasma membrane, to deliver their cargo, is the focus of intense investigation by many laboratories.
Adaptive association of inversions in a natural population of the malaria mosquito Anopheles messeae Fall

: The dependent combination of chromosomal variants by five paracentric inversions (IL1, IL2, IIR1, IIIR1, IIIL1) in Anopheles messeae population from the West Siberia was discovered. It is found that the inversion interactions interactions are the same at both larval and imaginal parts of the population, and they are stable during four years of studying. The inversion of hetero- and homozygotes demonstrates identical properties, that is, phylogenetic secondary sequencies dominate in heterozygotes. Two associative groups of chromosome variants were revealed. The association correlates with geographic distribution and temporal dynamics of inversions and on the whole, it reflects the evolutionary history of inversion polymorphism in A. messeae. It is supposed that the adaptive association of inversions found is the high degree polymorphism formed and functioned on the basis of the groups of inversion chromosome blocks.
chondroitin sulfate proteoglycan

The possibility that some of the brain proteoglycans are receptor-like protein tyrosine phosphatases (PTPases) was investigated. Mem- brane-bound proteoglycan fractions were prepared from the postnuclear membrane fraction of &day-old rat brain by DEAE ion-exchange chrom- atography and CsCl density gradient centrifugation. The isolated proteoglycan fractions showed high PTPase specific activities together with the typical PTPase characteristics. Renaturation experiments indicated that chondroitin sulfate proteoglycans with 380-and 170-kDa core proteins carried the PTPase activity. The proteoglycan with 380-kDa core protein was identified as RPTP/S/( bearing HNK-1 carbohydrate.
Variation in female throat coloration in the tree lizard (Urosaurus ornatus): relation to reproductive cycle and fecundity

Females from many iguanid lizard species assume orange or red coloration on their bodies about the time of ovulation and into their gravid period. We investigated whether the orange color sometimes seen on throats of female tree lizards, Urosaurus ornatus, was correlated with reproductive condition. We examined females collected bi-weekly from two populations. All females from the Donia Ana Mountains had orange throats which exhibited an insignificant tendency toward deeper orange in gravid and near gravid females. Females from Aguirre Spring, however, were polymorphic (yellow, gold, or pale orange) with respect to throat coloration early in the activity season. Later on, females carrying enlarged follicles exhibited a deep orange throat coloration, similar to females at Donia Ana. This color change was especially significant during the first of two annual clutches. We also observed that for the Aguirre Spring population both body size and throat color were good predictors of clutch size.
