Opis:
W ciągu ostatnich lat polska prasa poświęciła sporo miejsca zagadnieniu in vitro, ukazując przy tym stan świadomości publiczności i wzmacniając spór światopoglądowy w polskiej opinii publicznej. Ograniczając się do analizy kilku ostatnich lat, przeglądając zawartość tylko wybranych ze względu na wyrazistość przekazu artykułów, trzeba stwierdzić, że sama temperatura debaty skłania do analizy argumentacji. Debacie autorytetów, publicystów i dziennikarzy towarzyszy opis aktualnego stanu polskiej opinii publicznej w kwestii sztucznego zapłodnienia. W kształtowaniu opinii społecznej gazety świeckie zdają się coraz częściej porzucać etyczny argument dotyczący godności ludzkiej osoby i ochrony embrionów. W tym miejscu rodzi się pytanie: czy chrześcijańskie, bardzo ostrożne podejście do technologii biomedycznych musi przegrać w medialnych przekazach z narzuconą przez wydawców laickich poprawnością polityczną i zgodą na in vitro? Coraz więcej czytelników podziela dziś opinię o konieczności istnienia wysokich standardów etycznych w codziennej pracy dziennikarzy zwanych ogólnie przez papieża Benedykta XVI infoetyką. W przeciwnym razie społeczeństwu grozi niedoinformowanie. W takim wypadku nie unikniemy już w najbliższej przyszłości rozgoryczenia w spotkaniu ze skutkami medialnych błędów. Dyskusja o in vitro staje się w tej dziedzinie prawdziwym sprawdzianem rzetelności dziennikarskiej.
In recent years, the Polish press has devoted a great deal of attention to the question of IVF (in vitro fertilization) thus revealing the level of public awareness on the issue and exposing the controversy in world-view matters among Polish public opinion. Taking into account the content and clarity of selected articles in the last few years, one can claim that the heated debate requires a more in–depth analysis. The issues raised in the debate among experts and journalists are accompanied by a description of the current state of Polish public opinion on the problem of IVF. The secular press often dismisses the ethical argument related to the dignity of the human person and the protection of embryos in an attempt to influence public opinion. This begs the question: Does political correctness and acceptance of IVF upheld by the secular media place the very cautious Christian approach to biomedical technology on the losing side? Nowadays, the general public sees the need for high ethical standards in the daily work of journalists which Benedict XV1 referred to in general terms as infoethics. Otherwise, there is a danger of the public not being adequately informed. In this case, the consequences of the media’s failures may lead to widespread bitterness in the foreseeable future. It is believed that the media debate on IVF will become a true test of journalistic integrity.

Opis:
In Poland, the in vitro fertilisation method has been used for over 25 years to treat infertile couples. The issues associated with IVF are permanently raised in parliamentary debates. The discussion in the parliament relates above all to the question who could benefit from the refund of the in vitro fertilization method, and on what basis. A statutory solution to the problem seems remote, if only because in the ruling party itself there are two bills and there is no consensus. However, there is one temporary solution, i.e. a health programme of the Minister of Health: Treatment of Infertility by IVF Method.

Opis:
Il diritto alla vita è una legge fondamentale che scaturisce dalla dignità umana. L’articolo presenta la situazione giuridica dell’embrione preimpianto nella legge polacca. Vi sono sottolineati i valori costituzionali, che tutelano la vita umana precoce (anzitutto gli articoli 30 e 38 della Costituzione della Repubblica Polacca). Nella giurisprudenza polacca la vita prenatale è un valore costituzione che non può essere discriminato (Sentenza del Tribunale Costituzionale 28 maggio del 1997). La Legge del 25 giugno del 2015 non tutela però in modo adeguato l’embrione nella fase primordiale. La fecondazione medicalmente assistita(anche eterologa), l’ammissibilità alla selezione degli embrioni, il congelamento dei gameti o degli embrioni, forniscono motivi di chiamare – dal punto di vista morale – la legge sulla cura dell’infertilità come legge ingiusta.
Right to life is a fundamental right which stems from human dignity. The article presents legal situation of an embryo on pre-implantation phase in the Polish public order. The article highlights the constitutional values protecting human life (paragraph 30 and 38 of the Constitution of the Republic of Poland). Life in prenatal phase is a constitutional value in Polishjurisprudence (Adjudication of Polish Constitutional Court on 28th May 1997). The act of law passed on 25th June 2015 does not protect in sufficient way the embryo which comes into being during an in-vitro procedure. The law on infertility treatment which allows medically assisted fertilization (also heterologous), selection of embryos, embryo and gamete freezing may be recognise only as injustice from the moral point of view.

Opis:
The aim of the studies was to establish in vitro conditions for the culture of pea and lupin embryos as the first step in the development of an in vitro assisted single seed descent technique for the attainment of homozygous populations. Materials for the study included of pea, and narrow-leafed and yellow lupin cultivars. Embryos dissected from mature but still-green seeds were cultured in vitro on two modified MS media and under three temperature regimes. Shoot and root lengths of regenerated plants were measured after 7, 14 and 21 days of culture. For pea plants full-strength MS medium with 4 g l−1 agar and temperature 22/ 20°C (day/night) appeared to be the most conducive to shoot and root development, whereas for lupin plants lower temperatures were more propitious: 12°C in the dark for narrow-leafed lupin and 16/ 12°C (day/night) for yellow lupin. Almost all the cultured embryos developed into plants, but not all the regenerated plants survived acclimation to ex vitro conditions.

Opis:
W trakcie niemalże półwiekowego rozwoju techniki zapłodnienia in vitro nie tylko stały się popularne i dostępne, ale także zyskały etyczną akceptację nawet w środowiskach katolickich, mimo jednoznacznie negatywnej oceny Magisterium Kościoła. W artykule została najpierw podjęta dyskusja z emocjonalnymi i perswazyjnymi argumentami przeciwników i zwolenników tej procedura. Poważne argumenty skupiają się jednak wokół dwóch kwestii: z jednej strony losu embrionów, które giną w trakcie stosowania tej procedury, z drugiej zaś rozdzielenia poczęcia nowej osoby od aktu seksualnego rodziców. Zastrzeżenia te nie straciły nic ze swojej aktualności i wagi moralnej, dlatego też katoliccy rodzice, mimo niewątpliwie dotkliwego cierpienia, jakie jest związane z niepłodnością, powinni zachować krytyczny dystans wobec zapłodnienia in vitro.
Over the course of almost half a century of development, in vitro fertilisation techniques have not only become popular and accessible, but have also gained ethical acceptance even in Catholic circles, despite the unequivocally negative assessment of the Church’s Magisterium. The paper addresses the emotional and persuasive arguments of opponents and supporters of this procedure. The serious arguments,revolve around two issues: on the one hand, the fate of embryos that perish in the course of this procedureand, on the other hand, the separation of the conception of a new person from the parents’ sexual act. These objections have lost none of their relevance and moral weight, which is why Catholic parents, despite the undoubtedly acute suffering that is associatedwith infertility, should maintain a critical and distanced outlook on in vitro fertilisation.

Opis:
Investigations were conducted on the strongly infested by microbes embryos isolated from seed stratified in non-sterile conditions or from tree buds. The results showed, that PPM (Plant Preservative Mixture, produced by Plant Cell Technology, Inc.) was very useful for increasing the percentage of sterile cultures disinfected in a 5% solution of NaOCl. The best way of applying PPM turned out to be adding the substance directly to the growing medium. At the concentration of 2 or 4 cm3 x dm-3 of PPM there was an 30% increase in percentage of sterile of in vitro cultures developed from embryos and 70-80% of cultures developed from buds, as compared with the control without PPM. At the range of concentrations employed in this study, no negative effects of PPM upon the development and growth of callus were observed.

Opis:
Plants were regenerated from immature embryo cultures of 35 winter wheat genotypes. General responses of regenerated plants were investigated and a total of 7142 R₂ spike lines from 1593 R₁ plants were assessed in the field for somaclonal variants in 1985/86, 1986/87 and 1987/88. Selected variants were studied for their possible genetic inheritance. From regenerated plantlets, 81% survived and 63% produced fertile plants. Forms with reduced plant height, length of spike and other morphological abnormalities were found in this progeny. Populations of R₁ plants were highly variable due mainly to the physiological disturbances resulting from the in vitro process. Overall somaclonal variation frequencies were 14.2% per plant basis and 5.3% per R₂ spike basis. The variants were similar in the three different R₂ generations with predominant variants being negative in plant height, maturity, awns, spike type and plant type. Both uniform R₂ variant families and spike lines were found in addition to the segregating variants which constituted the majority. On average, in a variant family or line, 18% and 14% of their component lines and plants were variants, respectively. Inheritability was demonstrated for the uniform variant families and spike lines as well as segregated variants. Of those 134 selections, about 70% were classified as inheritable. Both recessive and dominant gene mutations at one, two or three loci were evident in some variants as suggested by the segregating data.

Opis:
Several aspects of in vitro culture have potential for cereal improvement. This paper focuses on evaluation of somaclonal variation (SV) from immature embryo callus culture, and doubled haploid (DH) production via anther culture in barley. Genetically stable SV was observed for several seedling morphological traits such as albino, yellow, light green and lethal. SV occurred at approximately half the frequency of azide-induced mutagenesis. The potential for widespread application of anther culture-mediated DH production in barley breeding and genetic studies was increased through culture procedure improvements and understanding the inheritance of anther culture response. Methodology improvements included substitution of inexpensive gelrite for expensive ficoll or agarose, ability to grow anther donor plants under field as well as growth chamber conditions and flexibility in cold pretreatment/storage of anther donor spikes for 4-6 weeks prior to anther plating. From diallel analysis, inheritance of anther culture response was complex with additive and dominance effects for embryoid formation, total plant regeneration and green plant regeneration and reciprocal effects (maternal) for green plant regeneration. High x low responder crosses generated F₁’s that were intermediate in response and low x low crosses sometimes produced F₁ heterosis for green plant regeneration. Therefore, some recalcitrant types appear to be usable in anther culture DH production systems within a breeding program.
