In the mid-1950's, fingernail clams virtually disappeared from a 100-mile section of the IL River, a tributary of the Mississippi River, due to unknown causes. A survey of the bottom fauna of the IL River in 1979, revealed that the clams were still absent from the middle reach of the River, where they had been abundant prior to the die-off in the 1950's. Some factor(s) in the River currently prevent the clams from recolonizing areas where they were formerly abundant. Recently, clams exposed to fluoride developed abnormal grooves in the shell matrix. Fluorides are known to be protoplasmic poisons removing essential body calcium by precipitation. Since the shell consists primarily of Ca carbonate, this investigation examines the possible role of fluoride on shell formation and the poisoning of the Ca pump which can directly inhibit lateral ciliary activity on the gill.

In the Ob river floodplain between the mouths of its tributaries Vakh and Tym (within the limits of Aleksandrovskiy district of Tomsk region), phytocoenoses belonging to 9 associations and 2 communities of Braun-Blanquet classification vegetation classes are listed. Class Lemnetea is represented by associations Ricciocarpetum natantis (Segal 1963) Tx. 1974, Lemnetum trisulcae Soó 1927, Stratiotetum aloidis Miljan 1933; class Potametea is done by asso­ciations Potametum perfoliati Koch 1926, Myriophylletum sibirici Taran 1998, Myriophylletum verticillati Soó 1927, Potametum graminei Koch 1926, Potametum pectinati Carstensen 1955, Nymphoidetum peltatae (All. 1922) Bellot 1951, as well as Sagittaria natans and Potamogeton natans—Ceratophyllum demersum communities. The syntaxa distribution in Western Siberia and adjoining territories is characterized.

The article considers the historical and cultural heritage of villages of the former Ketskaya volost, which is currently a part of the Tomsk region. The formation of Ketsky prison and the architecture of large settlements of the former Ketskaya volost are studied. Little is known about the historical and cultural heritage of villages of the Tomsk region and the problems of preserving historical settlements of the country.The aim of this work is to study the formation and development of the village architecture of the former Ketskaya volost, currently included in the Tomsk region.The following scientific methods are used: a critical analysis of the literature, comparative architectural analysis and systems analysis of information, creative synthesis of the findings. The obtained results can be used in preparation of lectures, reports and communication on the history of the Siberian architecture.The scientific novelty is a study of the historical and cultural heritage of large settlements of the former Ketskaya volost, which has not been studied and published before. The methodological and theoretical basis of the study is theoretical works of historians and architects regarding the issue under study as well as the previous  author’s work in the field.It is found that the historical and cultural heritage of the villages of the former Ketskaya volost has a rich history. Old historical buildings, including religious ones are preserved in villages of Togur and Novoilinka. The urban planning of the villages reflects the design and construction principles of the 18th century. The rich natural environment gives this area a special touch.

Respiratory system cancer (cancer of the nasal cavity, middle ear, paranasal sinuses (C30-31), larynx (C32), trachea, bronchi and lung (C33-34) is one of the most common malignancies in the Tomsk region, comprising 12.9% of all cancer cases. The purpose of the study was to analyze the respiratory system cancer incidence among the population of the Tomsk region. Materials and methods. The study was based on cancer register data collected at the Cancer Research Institute and Tomsk Regional Cancer Center, and covered the period 2005-2016. Results. Respiratory system cancer is the most common cancer in men, comprising 21.7% and the 6-th most common cancer in women, comprising 5.1. The incidence of respiratory system cancer decreased in men and showed an increasing tendency in women. The age-standardized incidence rates in the Tomsk region were expected to be 58.3 per 100,000 males and 12.8 per 100,000 females by 2020. Conclusion. Early detection and prediction of respiratory system cancer should play a vital role in the diagnosis process and also increase the survival rate of patient.

The isotopic (234U/238U, 2H, 18O) and chemical composition of groundwater on the right bank of the Volga River along the middle reach (European Russia) was studied down to a depth of 400 m. These data allow diagnosis of the presence of a three-component mixture. The first component is modern/young fresh recharge water of the Holocene age. It has the isotopic composition of water δ18O → −12.9 ‰ and δ2H → −90 ‰, close to modern precipitations, and the equilibrium isotopic composition of uranium 234U/238U → 1 (by activity). The second component is slightly salted water of the late or postglacial period with δ18O → −17.0 ‰ and δ2H → −119 ‰, and a small excess of uranium-234 234U/238U ≈ 4. The third component is meltwater formed as result of permafrost thawing. It is brackish water with δ18O ≈ −15.0 ‰ and δ2H ≈ −110 ‰, and a maximum excess of uranium-234 234U/238U ≈ 15.7. The salinity of this water is associated with an increase of the SO42−, Ca2+ and Na+ content, and this may be due to the presence of gypsum in water-bearing sediments, because the solubility of sulfates increases at near-zero temperature. We explain the huge excess of uranium-234 by its accumulation in the mineral lattice during the glacial age and quick leaching after thawing of permafrost.
