Opis:: Rare and endemic plant species represent important components of plant biodiversity which require protection to ensure their sustainable conservation. Cerastium banaticum (Rochel) Heuff. is such an endemic and rare species from Romania, for which the genetic variability of two natural populations was studied by SSR markers. Shannon’s information index revealed low levels of genetic diversity in both populations (I = 0.296). As the first attempt in a conservation program a reproducible micropropagation protocol was established starting from seeds, followed by multiplication, rooting, and ex vitro acclimatization. Among the various plant growth regulators tested the highest multiplication coefficient was achieved on a culture medium with 0.5 mg L -1 6-furfurylaminopurine (K) and 1 mg L -1 α-naphthaleneacetic acid (NAA). On this PGRs concentration a number of 26.6 shoots/individual explant with a mean length of 7.9 cm for new generated shoots was registered. The highest number of roots/indi- vidual initiated shoot was 2.6 and it was recorded on a culture medium with 0.5 mg L -1 2-isopentyl-adenine (2iP) and 0.1 mg L -1 NAA. The outdoor acclimatization was successfully performed in a specially designed rocky area in the ‘Alexandru Borza’ Botanical Garden, Cluj-Napoca (Romania).

Opis:: The present report illustrates an improved and reproducible micropropagation system for economically valuable bamboo species Pseudoxytenanthera stocksii using nodal segments. Direct organogenesis from nodal segments was accomplished by culturing on Murashige and Skoog (MS) medium supplemented with 6.0 mg/L 6-benzylaminopurine (BAP). On this medium combination 9.0±0.25 shoots per explant were induced. Shoot multiplication was subjective to the combination of auxins and cytokinins concentrations used and number of repeated transfer of mother explants or subculturing of in vitro regenerated shoot clumps on fresh medium. Maximum 41.9±1.00 shoots were observed on MS medium supplemented with 4.0 mg/L of BAP and 0.25 mg/L of naphthalene acetic acid (NAA). Half strength MS medium containing various concentrations of auxins was used for in vitro root formation. Successful rooting with maximum response was achieved on half strength MS medium + 50% sucrose and 1.0 mg/L IBA (24.3±0.27 roots). The rooted plantlets were planted the soilrite and hardened in the greenhouse for 6-8 weeks. Completely acclimatized plantlets exhibited 96% survivability. The present propagation protocol could satisfy the demand of P. stocksii and could be explored for the commercial propagation of this valuable manga bamboo.

Opis:: The maintenance of Phytophthora infestans cultures isolates from blighted potato, frozen in liquid nitrogen, was studied in two experiments. The effects of deep freezing and acclimatization pre-treatment at different temperatures on culture survival and stability of virulence and aggressiveness were evaluated. The best survival of cultures maintained for three months in liquid nitrogen was expressed, when cultures were acclimatized before freezing at 7˚C. The survival of frozen cultures was significantly worse in comparison with control combinations stored on rye-agar and rye-agar under paraffin oil for short time (in experiment I – 40 days, in experiment II – three months). The virulence spectrum of frozen cultures after thawing was more narrow than that one observed before culture freezing. However this virulence spectrum did not differ significantly from virulence range of control cultures. The level of aggressiveness of culture stored in liquid nitrogen did not differ significantly from control cultures as well. The virulence spectrum and aggressiveness level of cultures frozen in liquid nitrogen were significantly higher after two passages of thawed cultures on potato tissues than after single passage.

Opis:: Background: The effect of sleeping positions during acclimatization to high altitude on Acute Mountain Sickness (AMS) and High Altitude Pulmonary Edema (HAPE) is unknown. We tested whether sleeping with the upper body raised by 5° reduces prevalence and severity of symptoms of AMS as well as of elevated pulmonary artery systolic pressure (PASP) values as a risk factor of HAPE. Methods: Randomly assigning trekking tourist volunteers n = 44 (25 m, 19 f; mean age 42.9 yr) sleeping at 4280 m or 5170 m to the experimental group (upper body elevated by 5°), or to the control group. After exclusion of other reasons for AMS-like symptoms those assumed to be related to AMS were rated by Lake Louise Score questionnaire in the evening and the following morning of the study. Transthoracic echocardiography was performed on both occasions to estimate PASP. Results: In the study group, symptoms of AMS were significantly reduced in younger subjects (p = 0.021), prevalence of AMS was reduced in women (p = 0.156), and PASP values were significantly reduced in older subjects and men (p = 0.032; p = 0.031 respectively). Conclusion: Results suggest that sleeping with the upper body in elevated position during a high altitude ascent may benefit those suffering from AMS or at risk of HAPE due to elevated PASP values.

Opis:: Dirofilariosis caused by the Dirofilaria repens nematodes is widely dispersed in southern Europe, Asia and Africa among dogs, cats, other carnivores and occasionally, humans. The first case of D. repens infection, found in Poland in 2007, concerned humans. In 2009, dirofilariosis was first registered in dogs in 3 focuses in central Poland, Warsaw, Pruszków and Żyrardów, whose range grew considerably with the subsequent identification of D. repens microfilariae in 119 dogs in Warsaw and 18 districts of the Mazowieckie Province. The microfilariae of D. repens were found in blood samples taken from 1588 dogs from all 16 provinces of Poland. D. repens was also recently detected in a mixture of Culex pipiens and Aedes vexans mosquitoes collected in Mazowieckie Province using Real Time PCR. The results of this study confirms the acclimatisation of D. repens on the territory of Poland and a possibility for it to close its life cycle in domestic species of mosquito.

Opis:: Shoot tips of Tibouchina urvilleana Cogn. were cultured 4 weeks in vitro in modified Murashige and Skoog (MS) [1962] medium supplemented with growth retardants: paclobutrazol – 0.1, 0.5, 1.0, 5.0 mg·dm⁻³, flurprimidol – 0.1, 1.0, 5.0 mg·dm⁻³, chlorocholine chloride (CCC) – 5.0, 50.0, 250.0 mg·dm⁻³. Explants cultured on the medium without growth substances were used as a control. Rooted microcuttings were transferred to the greenhouse and transplanted into a mixture of 1 peat : 1 perlite, where they were grown for 5 weeks. Plants were then cultivated in a peat substrate during another 5 weeks. Acclimatization of rooted shoots in the greenhouse was affective in 92.5–100%. The survival of plants was lowest when microcuttings were previously cultured on medium with flurprimidol at 5.0 mg·dm⁻³. Cultivation of Tibouchina urvilleana shoots in vitro on media with various growth retardants had a significant effect on the further growth of plants ex vitro. Paclobutrazol and flurprimidol at 5.0 mg·dm⁻³ inhibited very strong growth of plants after 10 weeks of growth ex vitro.
Wierzchołki pędów Tibouchina urvilleana Cogn. prowadzono 4 tygodnie in vitro na zmodyfikowanej pożywce Murashige i Skooga (MS) [1962] z dodatkiem retardantów wzrostu: paklobutrazol – 0,1; 0,5; 1,0; 5,0 mg·dm⁻³, fluropirimidol – 0,1; 1,0; 5,0 mg·dm⁻³, chlorek chlorocholiny (CCC) – 5,0; 50,0; 250,0 mg·dm⁻³. Kontrolę stanowiła pożywka nie zawierająca retardantów wzrostu. Ukorzenione pędy przenoszono do szklarni i sadzono do mieszaniny torfu i perlitu (1:1), gdzie rosły przez 5 tygodni. Następnie rośliny przesadzono do substratu torfowego i uprawiano przez kolejne 5 tygodni. Rośliny przyjęły się w 92,5–100,0%. Najniższy procent przyjęć wykazywały rośliny pochodzące z pożywki zawierającej 5,0 mg·dm⁻³ fluropirimidolu. Wzrost in vitro pędów Tibouchina urvilleana na pożywce zawierającej retardanty wzrostu miał istotny wpływ na dalszy wzrost roślin w podłożu. Paklobutrazol i fluropirimidol w stężeniu 5,0 mg·dm⁻³ bardzo silnie hamowały wzrost roślin ex vitro po 10 tygodniach.

Opis:: Ludwik Mlokosevich (1831-1909) was a famous naturalist of Polish origin, who lived most of his life in Lagodekhi (Georgia). Based on an analysis of various sources, including, first of all, publications in the Caucasian press of the 19th century, articles and notes by Mlokosiewicz himself, about 70 named trees and other plants planted by him in his botanical garden on the estate and the regimental (military) garden in Lagodekhi for acclimatization, decorative and industrial purposes have been established. The data are of great interest to the history of Polish science abroad, but also for the history of botany and botanical gardens of the 19th and 20th centuries. This information will be used in the project which aims at revitalization of the Mlokosevich Botanical Garden, which is currently being carried out in Lagodekhi by a group of Polish specialists under the auspices of the Council of Botanical Gardens in Poland.

Opis:: Introduction: Normobaric hypoxic training (NHT) for preacclimatization at home has found its way into commercial expedition mountaineering. Portable NH-generators produce a normobaric hypoxic gas mixture that can be inhaled using breathing masks at rest or during exercise or it can be pumped into lightweight tents for sleeping. These devices can be rented from commercial companies.Materials and methods: Prior to an expedition to Manaslu (8163 m) NHT was used for preacclimatization over a period of 10 days. Our regimen involved a greater increase in sleeping altitude (10 nights to reach 5400 m) than recommended by the rental company (30 nights to reach 3900 m). Results: No incidents occurred during NHT. Our regimen induced sufficient acclimatization to Manaslu Base Camp (4900 m), as evidenced by the fact that none of the expedition members suffered from AMS although they reached base camp within 2 days from Kathmandu – by helicopter flight to 3500 m and a one day walk the next day. Eight days after leaving Kathmandu, camp III was reached at 6850 m.Conclusions: At natural altitudes above 2500 m an increase of sleeping altitude should not exceed 300-500 m per day. Below 2500 m, there are no restrictions. It is therefore unclear why the company recommends such a slow increase in sleeping altitude. In our opinion, it is not necessary for healthy persons to start with a sleeping altitude below 2500 m. In contrast to natural altitudes, NH exposure can be instantly stopped if symptoms occur. Therefore, it seems safe to expose healthy persons to more liberal normobarichypoxic conditions.
