Abstract It is widely debated whether creole languages form a typological class; however, crosslinguistic generalizations from functional typology are seldom tested in creoles. Typological studies report a strong crosslinguistic tendency for asymmetries in habitual grammatical expressions across the present and past temporal reference domains (Bybee, 1994:245–8; Bybee, Perkins, & Pagliuca, 1994:151–60). This study analyzes two linguistic variants, preverbal asé and zero, which compete for habitual marking in Palenquero Creole (Colombia). I ask here: To what degree does the linguistic patterning of these forms conform to the crosslinguistic tendency? Results show that, despite Palenquero having widely cited creole features (e.g., preverbal markers and bare verb stems), the asymmetrical expression, distribution, and relative ordering of forms in the variable contexts closely align with crosslinguistic predictions for habituals, thus giving convincing evidence of typological markedness and not a Creole Prototype.

This paper examines the past temporal reference system in two data sets representing "early" Black English: Sarnana and the Ex-slave Recordings, with a view to discovering the structure underlying variable use of overt verbal morphology. Extrapolating from proposals in the literature on the behavior of past temporal reference structures in known creoles, as well as in black and white vernaculars, we propose and test an analytical model based on quantitative methodology and making use of the stepwise selection procedure incorporated in a variable rule analysis. Competing hypotheses were operationalized as factors in the analysis and systematically tested on the same data set. Perhaps the most striking result of our study is that no matter which way the data are configured, the same three factor effects obtain. These reflect general constraints on language use and language processing rather than specific creole phenomena, such as the patterning expected of a relative tense system sensitive to stativity and anteriority. These findings lead us to suggest not only that an English-like system of absolute tense marking, expressed by both marked and unmarked verbs, prevails in these materials, but also that the temporal organization of these materials is not consistent with what has been posited for creole languages.

Biologic Factors

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

Perfusion Fixation

Microbodies have received extensive morphological and cytochemical investigation since they were first described by Rhodin in 1954. To our knowledge, however, all investigations of microbodies and cytoplasmic bodies of rat renal proximal tubule cells have employed immersion fixation. Tisher, et al. have shown convincing evidence of fine structural alteration of microbodies in rhesus monkey kidney following immersion fixation; these alterations were not encountered when in vivo intravascular perfusion was employed. In view of these studies, and the fact that techniques for perfusion fixation have been established specifically for the rat kidney by Maunsbach, it seemed desirable to employ perfusion fixation to study the fine structure and distribution of microbodies and cytoplasmic bodies within the rat renal proximal tubule.

Sem Study

High school cosmetology students study the methods and effects of various human hair treatments, including permanents, straightening, conditioning, coloring and cutting. Although they are provided with textbook examples of overtreatment and numerous hair disorders and diseases, a view of an individual hair at the high resolution offered by an SEM provides convincing evidence of the hair‘s altered structure. Magnifications up to 2000X provide dramatic differences in perspective. A good quality classroom optical microscope can be very informative at lower resolutions.Students in a cosmetology class are initially split into two groups. One group is taught basic controls on the SEM (focus, magnification, brightness, contrast, specimen X, Y, and Z axis movements). A healthy, untreated piece of hair is initially examined on the SEM The second group cements a piece of their own hair on a stub. The samples are dryed quickly using heat or vacuum while the groups trade places and activities.

The Right

Spanish and English speakers tend to conceptualize time as running from left to right along a mental line. Previous research suggests that this representational strategy arises from the participants’ exposure to a left-to-right writing system. However, direct evidence supporting this assertion suffers from several limitations and relies only on the visual modality. This study subjected to a direct test the reading hypothesis using an auditory task. Participants from two groups (Spanish and Hebrew) differing in the directionality of their orthographic system had to discriminate temporal reference (past or future) of verbs and adverbs (referring to either past or future) auditorily presented to either the left or right ear by pressing a left or a right key. Spanish participants were faster responding to past words with the left hand and to future words with the right hand, whereas Hebrew participants showed the opposite pattern. Our results demonstrate that the left-right mapping of time is not restricted to the visual modality and that the direction of reading accounts for the preferred directionality of the mental time line. These results are discussed in the context of a possible mechanism underlying the effects of reading direction on highly abstract conceptual representations.

After a short overview of the history of probiotics, the author presents the development of human intestinal microflora based on the newest genetic data and the microbiological features of main probiotics. The indications of probiotic administration have been defined and extended in recent years. The author reviews significant results of probiotic treatment in some gastrointestinal diseases based on meta-analytical data. Probiotics are useful in preventing and treating diarrhoea caused by antibiotics and Clostridium difficile caused diarrhoea. In the treatment of Helicobacter pylori infection, preparations containing certain Lactobacillus,Bifidobacterium strains or Saccaromyces boulardii could enhance by 5–10% the rate of successful eradication and reduce the incidence and severity of the side effects. Some symptoms of irritable bowel syndrome and thus the quality of life can be improved by probiotics. Their beneficial effect in ulcerative colitis was proven, while in Crohn’s disease has not yet been defined. The use of probiotics is not included in guidelines, with the exception of the Maastricht IV/Florence consensus. For each disease it is advisable to use probiotics containing strains only with proven beneficial effect. The efficiency of preparations containing mixed strains has not yet been properly investigated. The author reviews the rare but potentially serious side effects of probiotics. In Hungary, there are many probiotic preparations available which can be purchased in pharmacies without prescription: their use is more empirical than evidence-based. The European Food Safety Authority has recently rejected claims for probiotics to be classed as medicines given the lack of convincing evidence on the effects of probiotics on human health and well-being. Clearly, further research is needed to collect evidence which could be incorporated into the international guidelines. Orv. Hetil., 2013, 154, 294–304.

The current adverse situation associated with the presence of a pandemic of allergic diseases is due to the lack of a scientifically based concept of treatment and prevention. The increased interest of researchers from different countries in the formation of immunological tolerance by modeling the intestinal microbiota is of high importance. Methods of influence on the microbial communities of the child's intestine should be as delicate as possible, taking into account the individual genetic characteristics of the microecosystem and the possibility of anaphylaxis. Until now, probiotic drugs have been widely used to correct dysbiosis, but data is gradually accumulating that there is no convincing evidence base for their use for the treatment and prevention of atopy. The use of bacteriophages is very relevant and one of the promising, actively studied areas of correction of intestinal biocenosis today, which are an alternative to antibiotic and probiotic medications. Selective decontamination of representatives of opportunistic flora, as the main factor in the implementation of the atopic phenotype, makes it possible to preserve and accelerate the formation of a unique and individual composition of the intestinal microbiota of the child, which can form an immunoregulatory balance. More than a century of experience in the use of bacteriophages indicates the safety of their use. Today, bacteriophages are actively used in various fields of practical medicine − obstetrics-gynecology, perinatology, urology, pediatric otorhinolaryngology, in the treatment of purulent-septic and intestinal infections. In some cases, bacteriophages are very effective against antibiotic-resistant pathogens. The active personalized use of bacteriophages in real clinical practice will make it possible to solve a number of serious, long-standing health problems in the Russian Federation and to win a world priority in this direction.

One of the malignant neoplasms, which is associated with exposure to only one factor - asbestos fibers, is malignant mesothelioma. At the same time, today there is already convincing evidence of its polyetiology. This indicates the urgent need to expand research in this direction in order to develop targeted preventive measures.
