Biodiversity of yeasts isolated during spontaneous fermentation of cool climate grape musts.

Biodiversity of native yeasts, especially in winemaking, has hidden potential. In order to use the value of non-Saccharomyces strains in wine production and to minimise the possibility of its deterioration, it is necessary to thoroughly study the yeast cultures present on grape fruits and in grape must, as well as their metabolic properties. The aim of the study was to characterise the yeast microbiota found during spontaneous fermentation of grape musts obtained from grape varieties 'Rondo', 'Regent' and 'Johanniter'. Grapes from two vineyards (Srebrna Góra and Zadora) located in southern Poland were used for the research. Succession of subsequent groups of yeasts was observed during the process. Metschnikowia pulcherrima yeasts were identified both at the beginning and the end of the process. Hanseniaspora uvarum, Wickerhamomyces onychis and Torulaspora delbrueckii strains were also identified during the fermentation. Torulaspora delbrueckii and Wickerhamomyces onychis strains were identified only in grape musts obtained from grapes of the Zadora vineyard. These strains may be characteristic of this vineyard and shape the identity of wines formed in it. Our research has provided specific knowledge on the biodiversity of yeast cultures on grapes and during their spontaneous fermentation. The research results presented indicate the possibility of using native strains for fermentation of grape musts, allowing to obtain a product with favourable chemical composition and sensory profile.

Teodora Krajewska, Official Female Doctor of Tuzla and Sarajevo: Medical Practitioner, Woman of Science, Polish Patriot and Feminist.

A biographical note on Teodora Krajewska (1854-1935) reveals the details of her life and professional activities as an Austro-Hungarian and Yugoslav health officer (Amtsärztin) in Tuzla (1893-1899) and in Sarajevo (1899-1923). Teodora Krajewska, née Kosmowska was the third of nine official female doctors employed by the Austro-Hungarian administration in occupied Bosnia and Herzegovina (BH: 1878-1918) and charged with the special task of popularising public health and hygiene, particularly among Muslim women. A Polish intellectual and fervent patriot from Warsaw, Krajewska had left Congress Poland as a young widow in 1883 to study medicine in Geneva, Switzerland. In 1890, she became the first woman in Europe to be employed as an assistant professor at the medical faculty of the University of Geneva but was forced to resign in 1892. In the same year, she was both awarded her doctorate and appointed to the position of an Austro-Hungarian female health officer in Tuzla. After being nationalised in Austria, she reported for duty in Tuzla in March 1893. In 1899, she accepted her transfer to a newly created position in Sarajevo where she was active as an official physician until 1922/23. She contributed to contemporary medical science through her research on leprosy and osteomalacia in Bosnia. She returned to Warsaw in 1928 and devoted herself to the translation of Serbo-Croatian literature and writing her memoirs on her life and activities in BH.

Father Adam Wisniewski, MD, and his work for lepromatous patients in India.

Father Adam Wisniewski (1913-1987), who was a Pallottine and a medical doctor with specialization in tropical diseases, devoted his life to helping and curing leprosy patients in India. His life proved difficult and varied. He began his medical studies during World War II in occupied Warsaw. What is more, he participated in the Warsaw Uprising in 1944, for which he later received the Cross of Valour, one of the highest Polish commendations. He learned about leprosy in France and then moved to India to use his medical knowledge to treat lepers and stop the spread of the disease. He created a center for the impoverished at Jeevodaya, India, which is still serves as a refuge for patients with leprosy.

Leprosy - one of the many forgotten tropical diseases.

Leprosy or Hansen disease is caused by an infection of Mycobacterium leprae. The large number of undetected cases (2000-2012 years 4 mln people) remains a threat to the elimination of leprosy. Leprosy is an unheard in Poland and generally is considered a condition so "exotic" that it is not worth to spend more attention to it. Forgotten disease in developed countries still thrives in an environment of poor and uneducated. Regardless of the conclusion that in the 21st century none infectious disease should not be treated as a disease on the designated regions of the world, other than our own, it should be recalled that the M. leprae was discovered in Europe, where for many years there were leprosaria and still infectious hospitals in Great Brittan, France or Spain get patients suspected of leprosy. The mobility of the inhabitants of the globe caused by wars, ethnic conflicts or a simple tourism causes that any infectious disease can not be treated as solely limited to distant us regions. The best proof of this were the viral diseases, formerly found in only in Asia or Africa, and currently transmitted to Europe [1]. At any moment, we can stand up against the problem of diagnostics of humans toward leprosy. Many medical reports indicate that leprosy as a disease with many symptoms encountered difficulties in its diagnosis. Only the experience of medical professionals and good microbiological diagnosis may speed up the diagnosis of leprosy.

Mycological monitoring of selected aquatic ecosystems in the context of epidemiological hazards. Drinking water.

Many species of microfungi are reported in aquatic ecosystems with different frequency. Their number constantly fluctuates depending on the concentration of environmental and anthropogenic factors. Drinking water, tap and bottled, is essential for the proper functioning of the human body. It is also the main component of food and hence it should be safe for human health and free of contaminants. The mycological purity of tap water in two large cities in the region (Olsztyn and Ostroleka) and a small village (Gaglawki) as well as bottled, medium-mineralized and curative water stored under different conditions were tested. The laboratory investigations followed a pathway applied in diagnostic mycological laboratories. The conducted tests demonstrated that microfungi were found in tap water originating from the cities and in bottled water. The rural water supply system was free from contaminations. Eighteen species of microfungi were identified in tap water from Olsztyn and 9 species in tap water from Ostroleka. In bottled water, 13 fungal species were detected. Exophiala spinifera and Debaryomyces hansenii were recorded in the water supply systems of both cities, while one common species, i.e. Aspergillus fumigatus, was identified in tap water fromOstroleka and in bottled water. The conducted studies have significant practical implications, for instance in sanitary and epidemiological water evaluation and in medicine in the context of analysing the quality of drinking water in reference to health resorts and nosocomial infections.

Analysis of mercury levels in historical bone material from syphilitic subjects--pilot studies (short report).

The aim of the present work is to study the remains of seven individuals with typical symptoms of tertiary syphilis in terms of mercury content in bones, thereby verifying whether they were subjected to treatment and, if they were, how long their organisms were exposed to toxic mercury fumes. Mercury was used, mainly in the Middle Ages and in the early modern period, as a preventive measure in case of individuals suffering from syphilis, a venereal disease, and also leprosy. Syphilitic patients treated this way should demonstrate increased concentration of mercury in their bones. The skeletons studied in the present work originate from various archaeological sites in southern and north-central Poland. The analyses concerned individuals with diagnosed syphilis as well as healthy individuals who constituted the control group. The analyses were performed by the LA-ICP-MS technique, with the use of laser Nd: YAG, Macro, 266 nm, New Wave, USA, coupled with Spectrometer Elan DRC-e Perkin Elmer, USA. The content analysis of the studied bone material revealed with high probability that the contact method of mercurial treatment was used only in the case of two women from north-central Poland, deceased at the turn of the 15th century at the earliest.

[Outcome of operative treatment for supination-external rotation Lauge-Hansen stage IV ankle fractures]. / Ocena wyników leczenia zlaman kostek goleni typu supinacyjno-rotacyjnego IV stopnia wedlug Lauge-Hansena.

INTRODUCTION: Ankle fractures are among the most common musculoskeletal injures. These fractures occur with an overall age- and sex-adjusted incidence rate around 180 per 100 000 person-years. The most frequent mechanism is considered to be supination-external rotation (60 to 80% of all ankle fractures) consisting of pathologic external rotation of the foot initially placed in some degree of supination. According to Lauge-Hansen classification, ankle joint structures are damaged in a sequence where the final, stage IV injuries, represents transverse fracture of the medial malleolus or its equivalent-rupture of the deltoid ligament. AIM OF THE WORK: The aim of this study is to compare the results of two subtypes of supination-external rotation stage IV fractures. MATERIAL AND METHODS: 43 patients treated surgically in 2006 to 2007 at Authors institution because of stage IV supination-external rotation ankle fracture were submitted to retrospective analysis. There were 25 patients with bimalleolar fracture (type 1) and in 18 patients with lateral malleolar fracture with accompanying rupture of the deltoid ligament (type 2). The mean age was 46 years (from 20 to 82 years). Average follow up period was 37 months (from 24 to 46 months). For the evaluation of treatment AOFAS hind-foot score (American Orthopedic Foot and Ankle Society) was used. RESULTS: The mean AOFAS score scale for Type 1 fractures was 85 points and for type 2 was significantly higher and amounted to 91 points (p < 0.05). CONCLUSIONS: Supination-external rotation stage IV ankle fractures with medial malleolar fracture, requires the implementation of additional diagnostic and therapeutic strategies and procedures in order to improve the outcome of results.

[Quality of life in women after mastectomy]. / Jakosc zycia kobiet po mastektomii.

The aim of the study was evaluation of quality of life of women after radical mastectomy. It was assumed that cancer of the breast, treatment and results could cause the decrease of quality of life. 107 women aged from 40 to 75 years after radical mastectomy were examined. Questionnaire made by G. Hansen at Norwegian University of Sport and Physical Education was used in all women. Questionnaire consists of 4 parts and contains 87 questions concerning general and medical data, quality of life and physical activity. Examined women had not any problems in daily activity. Most of them (about 70%) had difficulty in physical effort, particularly using upper extremities. 60% of women did not work, but they had a hobby (about 70%). Housework and daily activity were less efficient in 80% women after radical mastectomy. We observed a change in psychical status of examined women. They had some problems with concentration, irritation, irritability and sleep. These problems did not influence the family relationships and contacts with other people. Instead we noticed change in self-rating of women after radical mastectomy. Removal of breast--attribute of femininity--changed sexuality, consciousness of femininity and appearance of an image. We observed "half woman complex" in examined women. Women evaluated status of their body and quality of life from 3 to 5 in 7-gradual scale.

PCR primers that can detect low levels of Mycobacterium leprae DNA.

There are several specific PCR-based methods to detect Mycobacterium leprae DNA, but the amplicons are quite large. For example, primers that target the 36-kDa antigen gene and are in common diagnostic use yield a 530-bp product. This may be a disadvantage when examining samples in which the DNA is likely to be damaged and fragmented. Therefore, two sets of M. leprae-specific nested primers were designed, based on existing primer pairs which have been shown to be specific for M. leprae. Primers that targeted the 18-kDa antigen gene gave an outer product of 136 bp and inner product of 110 bp. The primers based on the RLEP repetitive sequence yielded a 129-bp outer product and 99-bp nested product. With dilutions of a standard M. leprae killed whole-cell preparation as the source of DNA, both single-stage and nested PCR were performed after optimisation of the experimental conditions. Compared with the 36-kDa antigen gene primers, the 18-kDa antigen gene outer primers were 100-fold more sensitive and the RLEP outer primers were 1000-fold more sensitive. As an illustration of two possible applications of these new primers, positive results were obtained from three skin slit samples from treated lepromatous leprosy patients and three archaeological samples from human remains showing typical leprosy palaeopathology. It was concluded that these new primers are a useful means of detecting M. leprae DNA which is damaged or present at a very low level.
