Opis:: Introduction and aim. Smoking widely affect oral health, including its role in the development of periodontitis. Saliva contains an antioxidant system and various enzymes. The study was designed to evaluate the activity of salivary alpha amylase among individuals who smoke and have periodontitis. Material and methods. A total of 100 participants were included, with 50 cases (cigarette smokers with periodontitis) and the remaining 50 nonsmokers with healthy periodontium as the control group. Saliva samples were collected to measure salivary alpha amylase activity. Results. Smokers with periodontitis had significantly higher levels of salivary alpha amylase compared to the control group(177.96±14.5 vs 94.04±19.6 IU/mL, p<0.001). Additionally, there was a weak negative correlation between the level of alpha amylase and the age of the patients (p=0.01, r=0.376). However, no correlation was found between the level of alpha amylase and the duration of smoking (p=0.584, r=0.079). Conclusion. There is a significant increase in salivary alpha amylase levels among smokers with periodontitis. No correlation was found between age and salivary alpha amylase levels. However, a weak positive correlation was observed between the duration of smoking and salivary alpha amylase activity.

Opis:: The aim of this study was to determine the quantitative and qualitative changes in the starch complex and the amylolytic activity of wheat grain during its post-harvest maturity. This in- formation is necessary for the proper determination of the level of quality requirements for wheat grain purchased immediately after harvest. The common wheat cultivars: Kandela, Bamberka and KWS Ozon were tested during this study. Because of the variability of weather conditions, three wheat cultivars were tested (two winter wheat cultivars and one spring wheat cultivar) from two consecu- tive crop years. Immediately after grain harvest and during the next 12 weeks in two-weeks intervals the falling number, amylo- graph properties, rheological properties of dough and laboratory baking test was performed. Tested wheat cultivars were characterized by low amylolytic activity. Changes of the baking value of tested wheat cultivars during their post-harvest maturation were dependent on wheat cultivar and harvest year. Wheat from the 2016 harvest was char- acterized by significantly lower amylolytic activity compared to grain from 2015 harvest. Amylolytic activity decreased during post-harvest maturation, i.e. the falling number increased as well as the dough torque in point C4 and C5 of mixolab curve. There was also an increase in the volume of bread compared to the evaluation of the samples tested immediately after harvest. The highest values were obtained in the 4th week after harvest. The changes were dependent on wheat cultivar. However, in the case of the assessment of the rheological characteristics of the dough (except point C4) they were not statistically significant.

Opis:: Starch can be found in microalgae, the raw material for the third generation of bioethanol production. One of them is C. pyrenoidosa. This study was conducted to analyze the effect of α-amylase enzyme concentration on the glucose contents produced and the effects of fermentation time on bioethanol contents produced. The hydrolysis process of this study was conducted using an α-amylase enzyme produced by A. niger. Several analyses in this research were carried out, including the analysis of enzyme activity using the Fuwa method, the analysis of glucose levels from enzymatic hydrolysis using the DNS method, and the analysis of bioethanol contents using the density method and GC-MS. The highest glucose content was 0.67 mg/mL, which was obtained from the addition of 40% (v/w) α-amylase enzyme, and the yield of bioethanol content from the sample treated 40% (v/w) α-amylase enzyme and fermented for 9 days was the optimum, which produced 28.07% of bioethanol content.

Opis:: Wzrastające zanieczyszczenie środowiska naturalnego, postępujący deficyt surowców kopalnianych oraz rosnące koszty pozyskiwania paliw konwencjonalnych spowodowały poszukiwanie alternatywnych źródeł energii. Celem pracy było wskazanie odmian kukurydzy zwyczajnej przydatnych do produkcji bioetanolu ze względu na wysoką aktywność amylolityczną ziarna. Aktywność α- amylazy oceniono metodą dyfuzji w żelu agarozowym i na podstawie liczby opadania według metodyki Hagberga-Pertena. Aktywność α- amylazy wahała się w granicach od 0,11 U·ml^-1 (Prosna) do 15,45 U·ml^-1 (Król) a liczba opadania od 61,0 s (Wilga) do 365,5 s (Blask). Najwyższą aktywność α- amylazy i niską liczbę opadania wykazały odmiany Wigo, Wilga, Cyrkon, Kosmo 230, Boruta, Kasia, Nimba, Iman, Król i Nysa. Ze względu na dużą zawartość endogennej alfa-amylazy, odmiany te mogą okazać się przydatne do produkcji bioetanolu.
Rising pollution of the environment, progressive shortage of natural resources, and rising costs of getting conventional fuel caused a search for alternative energy sources. The aim of the paper was to indicate the varieties of corn useful in production of bioethanol for the sake of high amylolythic activity of the grain. The activity of alpha-amylase was estimated with the method of diffusion in agarose gel and on the basis of the falling number according to the Hagberg-Perten’s methodology. The activity of alpha-amylase varied between 0,11 (Prosna) to 15,45 U·ml^-1 (Król), and the falling number between 61.0 s (Wilga) and 365.5 s (Blask). The highest activity of alpha-amylase and low falling number showed the varieties Wigo, Wilga, Cyrkon, Kosmo 230, Boruta, Kasia, Nimba, Iman, Król and Nysa. Because of high content of endogenous alpha-amylase these varieties can turn out to be useful in production of bioethanol.

Opis:: The tomato leaf miner, Tuta absoluta Meyrick (Lepidoptera: Gelechiidae), is one of the most destructive pest of solanaceae and it prefers tomato (Solanum lycopersicum L.). The aim of the current study was to investigate the effects of a wide range of seed proteinaceous extracts from different plant families against T. absoluta α-amylase activity. The effect of pH on the inhibitory activity of seed extracts showed that seed extracts of amaranth along with a wheat cultivar (Alvand, Aflak, Sarvdasht, Alborz, and Kavir) produced more than a 50% inhibition of the insect amylase. Aflak wheat seed extract at 10 μg, inhibited 81% of the insect amylase. This percent was the highest inhibition achieved. The other proteinaceous seed extracts had a lower effect on the enzymatic activity. Probit analysis showed that Aflak, Kavir, Alborz, Alvand, Sarvdasht, and amaranth inhibited the amylase activity with an I50 of 1.94, 3.24, 3.46, 3.31, 4.97, and 15.39 μg, respectively. The effect of pH on the inhibition of the α-amylase showed the highest inhibition of Amaranth and wheat, at a pH value of 8.0, which corresponds to the pH of the insect’s gut. Gel electrophoresis assays confirmed the spectrophotometric assays showing that the α-amylase of the insect gut was affected by the presence of the seed extracts. In the gel assay, a high concentration (14 μg protein) of amaranth proteinaceous seed extract greatly decreased the intensity of the α-amylase band. A high concentration of the Aflak wheat cultivar (10 μg protein) caused the disappearance of the amylase band in the gel. Thus, it is concluded that the physiochemical environment of the insect gut affects the interaction between digestive α-amylase and the metabolites. The experiments showed that seed proteinaceous extracts from non-host plant species, produced more inhibition of the insect amylase when compared to the host plant species. It appears that with evolution, adaptation took place so that insect/s could overcome the plant metabolites.

Opis:: α-Amylase isozymes from rye endosperm were analysed by means of isoelectric focusing, polyacrylamide gel electrophoresis, immunoelectrophoresis and colorimetric assay. Α-AMY 1 (high pI) group was separated into 13 IEF bands, whereas in group α-AMY2 (low pI) 2 intensive and 6-8 faint bands were found. Two linked (2±1 cM) polymorphic loci and a single locus with two alleles encoding for α-AMY 1 and α-AMY 2 groups, respectively, were identified after genetic analysis of the IEF patterns. All α-amylase isozymes developed on PAGE, were shown to belong to α-AMY 1 group. It was demonstrated that a single PAGE isozyme corresponds to 2-4 separate IEF bands and that most of the IEF bands can be attributed to more than one PAGE isozyme. The activity of α-amylases from PAGE zone I was 2.3 times higher than the activity of zone II isozymes. A strong correlation between the activity and protein amount of particular α-AMY 1 isozymes (r=0.94) was found.

Opis:: Genetic analysis of two rye interline crosses and a set of wheat/rye chromosomal addition lines was performed to reveal the mechanism underlying wide variation range of alpha-amylase activity in sound grain. The long arm of chromosome 6R was found to be responsible for increased enzyme synthesis during late stages of triticale grain maturation. Only nuclear genes seemed to control alpha-amylase activity, as reciprocal crosses between rye lines showed no maternal effects. Low enzyme activity showed complete dominance over high level of its synthesis. Segregation ratios, observed in F₂ and BC₁ crosses, indicated that recessive alleles at two independent duplicative loci underlie intensive alpha-amylase production.

Opis:: Introduction. The influence of infection with two species of entomopathogenic nematodes of Steinernematidae family on metabolism of glycogen and trehalose of the host was studied. Material and methods. Last instar larvae (L₇) of Galleria mellonella were experimentally infected with Steinernema affinis and S. feltiae. At 6, 12, 18 and 24 h after infection concentrations of trehalose and glycogen as well as activity of trehalase and α-amylase were determined. Results. The content of glycogen was lower in insects infected with S. feltiae than in the controls and animals infected with S. affinis. The content of trehalose was higher in insects from both infected groups than in the controls. Its concentration was slightly higher in larvae infected with S. affinis than in those infected with S. feltiae. The activity of α-amylase after infection with S. affinis was low. It was significantly higher in insects infected with S. feltiae. In animals of both infected groups, following a significant reduction at 6 h, the activity of trehalase remained at a similar level, higher than in the controls. In the paper the effects of infection with (i) different species of entomopathogenic nematodes and (ii) the importance of the developmental stage of the insect-host for changes in its metabolism of glycogen and trehalose were discussed.

Opis:: The albino Wistar rats were used to investigate the effect of thyroxine administration on the activity of citric acid, α-Amylase, creatine phosphokinase (CPK), creatinine, cholesterol and triglycerides level in blood serum and citric acid in liver and kidney. Two groups of rats were taken for the experiment. One group was injected subcutaneously with 200 μl of thyroxine/50 g of body weight, the other group served as control. The animals were vivisected with anesthesia after intervals of 24, 48, 72 and 96 hours α-Amylase and CPK levels in blood; citric acid level in liver and kidney of control and thyroxine treated rats. The results showed that the α-Amylase activity remained unaltered (100 g/h/l) throughout the experiment. However, citric acid level found to be 460 mg in the liver and 415 mg in kidney of control rats. The values slightly increased to 480 and 680 mg in respective tissues of thyroxine treated animals for 24 hr. The values decreased in 48 and 72 hours of treatment. Further the values found to be increased after 96 hours of treatment. Although the thyroxine treatment altered citric acid, Creatinine, Cholesterol, Triglycerides and CPK levels in the tissues, the serum α-Amylase was not influenced by the thyroxine. The study suggests that the thyroxine acts as a regulator all the above parameters in the cellular level.

Opis:: Single and double-gene Rhtl, Rht2, Rht3, Rht1 + Rht2 and Rht3 + Rht2 isogenic lines of wheat in four parental rht varieties were grown in drilled yield trials at four sites in 1989. The same lines were also grown in 1988 together with hybrid genotypes from CHA (chemical hybridising agent) F₁ production plots. In the inbred lines shorter than one metre, Rht alleles reduced total shoot biomass by shortening the straw; mass of straw per unit plant height was unaffected. Highest grain yield was obtained from plant heights between 70 and 100 cm. The Rht genotype achieving this stature varied according to parent varietal height. The hybrids grown allowed comparisons between intra- and inter-varietal crosses over a range of Rht genotypes. In F₁ hybrids positive heterosis was observed for plant height, grain yield and mean grain weight. Highest yields were obtained from inter-varietal hybrids carrying one, two or three doses of Rht1 or Rht2 or one dose of Rht3. An Rht3lrht hybrid showed resistance to premature α-amylase production during grain ripening.
