Compared to the known method of conjugation the frequency of transposon mutagenesis following conjugation was enhanced 11-fold by two hours of pre-incubation of recipient Pseudomonas viridiflava 1 on conjugation media. The increased frequency was ƒ = 1.3 × 10 −4 . In other species of Pseudomonas, Pectobacteira and Xanthomonas high rates of transposon mutants were similarly obtained; however, in these strains the increased frequency was less than 5-fold.

Abstract

Quality and storability are crucial factors in production of apple juice. The main goal of this study was investigation of the effects of ascorbic acid and acerola juice on the changes of some sensorial parameters and bioactive compounds of aseptically filled and industrial scale produced apple juice during storage for 12 months. While the viscosity and pH of apple juice did not change significantly, the ΔE* peaked (20–30) at month 6 of the storage period. The colour of apple juice was lighter than at the beginning of storage. Maximum total phenolic contents were 1,100, 1,400, and 1,250 mg L−1 in the control, ascorbic acid supplemented, and acerola added samples, respectively. Other parameters (antioxidant capacity, ascorbic acid, browning index, etc.) peaked in month 4. Acerola was a good alternative anti-browning and antioxidant agent for the treatment of apple juice in the processing. The antioxidant capacity of apple juice treated with acerola was higher than with ascorbic acid. The results were obtained with industrial samples, thus, they can serve as a very good base for the optimisation process and industrial production without the need for scale-up.

Some recent results on the synthesis of coiled carbon nanotubes (CNTs) are summarized. Several supported catalysts can lead to the formation of coiled CNTs. Interestingly, certain domains of the coil pitch and coil diameter are favoured, and two “stability islands”are found in the 3D representation of the number of coiled CNTs as a function of both coil pitch and coil diameter. It is emphasized that these nanotubes are formed either by introducing pairs of five-membered ring - seven-membered ring or by forming haeckelite structures. The coiled CNTs could be used in nanocomposite reinforcement as well as special sensors based on their remarkable mechanical and electrical properties.

Abstract

We report a case of an infant with spontaneous chylothorax due to the congenital malformation of a small lymph vessel of the chest wall. Conservative therapy with omitting long-chain fatty acids from the diet, fat-free nutrition, total parenteral nutrition and intravenous somatostatin did not result in the decrease of pleural effusion. Thoracic surgical intervention performing thoracic duct ligation and using fibrin sealants was applied after 10 days of unsuccessful conservative therapy, and resulted in the complete recovery of the patient. Our experience support the already existing observations, that in cases where the daily loss of chyle exceeds 100 ml per age years and/or lasts longer than 2 weeks, early surgical intervention is recommended.

E tanulmány célja a házastársi stressz kapcsolatának vizsgálata a magasvérnyomás-betegséggel és a depresszióval – 65 évnél fiatalabb, házasságban/élettársi kapcsolatban élő, gazdaságilag aktív személyek körében; országos reprezentatív mintán (Hungarostudy 2002). A házastársi stresszt a Rövidített Stockholmi Házastársi Stressz Skálával, a depressziós tüneteket a Rövidített Beck Depresszió Kérdőívvel mértük. Azok a férfiak és nők alkották a „magasvérnyomás-beteg”, illetve „depressziós” csoportokat, akiket az elmúlt évben kezeltek is betegségük miatt. Hierarchikus logisztikus regresszió-elemzéssel vizsgáltuk a házastársi stressz hatását a magasvérnyomás-beteg, illetve a depressziós páciensek körében, valamint egészséges férfiak és nők körében. Adatainkat kontrolláltuk életkorra, iskolai végzettségre, szocioökonómiai státuszra, testtömeg-indexre, valamint az életmódra (dohányzás, alkoholfogyasztás és fizikai aktivitás). Míg a férfiaknál a házastársi stressz a magasvérnyomás-betegség hagyományos rizikótényezőktől független kockázati tényezőjének bizonyult, addig a nőkre ez nem állt fenn. Egy rossz házasságban élő férfinak majdnem kétszer nagyobb az esélye arra, hogy magasvérnyomás-betegség miatt kezeljék, mint a jó házasságban élő férfitársának. Ugyanakkor nőknél a házastársi stressz a depresszió miatti kezelés valószínűségét növelte szignifikáns mértékben, ez pedig a férfiakra nem volt jellemző. Egy rossz házasságban élő nőnek több mint kétszer nagyobb az esélye arra, hogy depresszió miatt kezelésben részesüljön, mint a jó házasságban élő nőtársának. Elemezéseink tehát azt mutatták, hogy férfiaknál a házastársi stressz a magasvérnyomás-betegség független kockázati tényezője, viszont nőknél a házastársi stressz a klinikai depresszió kockázati tényezője.

The combined effect of surgical treatment and consumption of so-called “CoD™ tea” (containing Uncaria guianensis, U. tomentosa and Tabebuia avellanedae) on expression of c-myc, Ha-ras, Bcl-2, Ki-ras and p53 key onco/suppressor genes, the carbohydrate antigen (CA19-9) and carcino-embryonic antigen (CEA) tumour markers in blood samples of patients with colorectal cancer (CRC) were investigated. Expression of genes followed the effect of the surgical treatment combined with neoadjuvant chemotherapeutic treatment; this may predict the outcome of carcinoma. Moreover their expressions might show possible additional effect of supportive therapy, e.g. CoD™ consumption. The antioxidant capacity of blood was also examined. Blood samples were taken at the day of, and one week, 3, 6 and 12 months after the surgical treatment. During that period patients got 0.25 l standard portion of CoD™ tea three times a day. The surgical treatment and neoadjuvant therapy were able to suppress the expression of c-myc, Ha-ras, Bcl-2, Ki-ras, p53 genes up to the twelfth month. Moreover, CoD™ tea together with conventional treatment caused a strong decrease in the expression of c-myc and Ha-ras oncogenes in comparison to the non-consumer control.

The addition of synthetic (E)-anethol to the known attractant phenylacetaldehyde synergized attraction of the cotton bollworm Helicoverpa armigera, the blend invariably catching 4 to 6 times more than phenylacetaldehyde on its own. Highest catches were recorded by the 1:1-3:1 blends. The addition of salicyl aldehyde, ±linalool, (R)-(+)-limonene, 2-methoxybenzyl alcohol and 4-methoxybenzyl alcohol (compounds described earlier in the literature as co-attractants for H. armigera), increased catches when added to phenylacetaldehyde. However, the addition of these compounds did not increase catches of the (E)-anethol+pheny- lacetaldehyde blend. When directly compared with performance of the synthetic pheromone, the (E)-anethol +phenylacetaldehyde blend caught an average of 27% of the catch in pheromone baited traps. On an average 79% of moths caught in traps with the (E)-anethol+phenylacetaldehyde blend were females, while traps with pheromone caught only males. The (E)-anethol+phenylacetaldehyde blend described in this study may form the basis for the development of an efficient bisexual lure for H. armigera AFTER further optimization.
