This paper presents the results of the study of the ceramics collection from two periods — Eneolithic and Medie-val, assembled during the fieldwork at the ancient settlement of Ust-Vasyegan 1 in the Northern Priobye (Western Sibe-ria). The Eneolithic ware is represented by fragments of 30 vessels decorated with alveolate, rhombic, nail-imprints, and corner patterns. There are fragments of a boat-shaped vessel and vessels with handles. The complex has analogies in the materials of the settlement of Gorny Samotnel-1 and is dated to the end of the 4th–3rd centuries BC. The Medieval ceramics are represented by 296 vessels. On the basis of typological analysis, two groups of vessels have been identi-fied: group 1 ware with sparing ornamentation comprising 1–4 lines of the ornament; and group 2 ware with an orna-ment comprising 5–8 and more lines. A characteristic feature of the group 2 vessels is the use of a cord and various shaped stamps. In the cultural layer of the settlement, ceramics of both groups was deposited side by side, which sug-gests their contemporaneity. In order to determine the degree of similarity/difference of the derived groups of vessels, a technical-technological analysis was carried out on 20 items. It appeared that potters who manufactured the group 1 vessels routinely used blend compositions of grus and grus with wool. Organic mortars were rarely used. The smoo-thing of the vessels was performed mainly with a wood splinter, knife, or spatula. The craftsmen who manufactured the vessels of group 2 used medium to heavily oversanded clays along with slightly oversanded material. While making the molding compositions, a blend of grus and organic mortar was used more often. Wool was rarely utilised. The vessels were smoothed with soft materials and a knife or spatula, the outer surfaces were subjected to hand tamping. The noted differences suggest, that in the Middle Ages two groups of potters, who had distinctive pottery-making skills, were living at the settlement. Vessels of the group 1 have similarities with materials of the “Bichevnik” type from the Pechersky Trans-Urals, whereas vessels of the group 2 in the materials of the Yarsalinsky, Ust’-Poluisky, and Yudinsky Cultures of the Iron Age and Early Middle Ages of the Middle and Lower Priobye and Lower Tobol River region. Obtained radiocarbon dates and some artefacts (a bronze signet ring and an iron dagger), which have analogies in the Middle Trans-Urals, define the time span of the activity for the ancient settlement of Ust-Vasyegan 1 within the 7th–13th centuries.

A chronological framework for the prehistoric cultural complexes of Sakhalin Island is presented based on 160 radiocarbon dates from 74 sites. The earliest 14C-dated site, Ogonki 5, corresponds to the Upper Paleolithic, about 19,500–17,800 BP. According to the 14C data, since about 8800 BP, there is a continuous sequence of Neolithic, Early Iron Age, and Medieval complexes. The Neolithic existed during approximately 8800–2800 BP. Transitional Neolithic-Early Iron Age complexes are dated to about 2800–2300 BP. The Early Iron Age may be dated to about 2500–1300 BP. The Middle Ages period is dated to approximately 1300–300 BP (VII–XVII centuries AD).

Marine Protein

Stable isotope measurements and radiocarbon dates on 54 burials from northern Scotland document trends in marine protein consumption from the late Iron Age to the end of the Middle Ages. They illuminate how local environmental and cultural contingencies interrelated with a pan-European trend towards more intensive fishing around the end of the first millennium AD. Little use was made of marine foods in late Iron Age Orkney despite its maritime setting. Significant fish consumption appeared in the Viking Age (ninth to eleventh centuries AD), first in the case of some men buried with grave-goods of Scandinavian style but soon among both sexes in ‘Christian’ burials. There was then a peak in marine protein consumption from approximately the eleventh to the fourteenth centuries AD, particularly among men, after which the importance of fish-eating returned to Viking Age levels. The causes of these developments probably entailed a complex relationship between ethnicity, gender, Christian fasting practices, population growth, long-range fish trade and environmental change.

The paper presents the analysis of the natural and climatic conditions of the Early Iron and Middle Ages in the archaeological region of Priketye (Ket’ River region; Verkhneketsky district of the Tomsk Oblast, middle taiga) based on the available archaeological data and spore-and-pollen diagram of Maksimkin Yar, 58°30'N, 86°48'E, 100–150 m.a.s.l. (Blyakharchuk, 2012). The chronology of the archaeological sites and monuments covers a large time span — from the Neolithic to the late Middle Ages, including the time of the arrival of Russian farmers into the area. The aim of the study is to reconstruct the dynamics of the natural environment during the existence of the archaeological cultures of the indicated time interval using paleopalynological data from a nearby spore-and-pollen section, as well as to demonstrate the capabilities and advantages of complex paleoecological-archaeological research in the taiga zone of Western Siberia (middle course of the Ket’ River near the Maksimkin Yar village) previously not covered by such studies. The material and source of the archaeological data com-prised collections and archives of exploratory and stationary excavations of the archaeological sites from the area in the vicinity of the Maksimkin Yar village. Paleopalynological (spore-and-pollen diagram) and paleoecological (botanical composition of peat) data were obtained and published by one of the authors earlier (Blyakharchuk, 2012). In this work, comparative historical and statistical methods of the analysis of archaeological data were employed, along with two paleoecological methods (spore-and-pollen analysis and analysis of the botanical com-position of peat) with respective statistical processing of the numerical data from these analyses. The pa-leoecological block of information is presented graphically in the form of a spore-and-pollen diagram built on the basis of the paleopalynological data and two radiocarbon dates covering the studied time interval. The Bacon software was used to calibrate the radiocarbon dates and to date each sample. The studies have shown that the climate change in the boreal forest zone of Western Siberia influenced the lifestyle and economic activities of the population of the Priketye area. Correlation of the climatic and cultural events of the studied area with neighboring southwestern, southern, and southeastern regions showed their synchroneity with the dynamics of the hydrocli-mate on these territories. During the Iron Age and after the end of the late Middle Ages, there was a synchronous increase in humidity, both in the steppe zone and in the forest zone. In the Bronze Age and during the high Middle Ages, the steppe zone was humid, but less atmospheric precipitation fell out in the forest zone. These fluctuations in the moisture content are well correlated with the 500–600-year hydrological cycles in the steppe zone, identi-fied by geochemical indicators of the steppe Shira Lake in Khakassia (Kalugin et al., 2013, p. 251). Changes in the hydroclimatic conditions in the forest and steppe zones had different effects on the local cultures and could stimulate either their rise or decline, as well as migrations.

The horizons of slash-and-burn agriculture were distinguished by pedological, anthracological, phytolithic and palynological features. Radiocarbon dates were obtained from the coals. Most of the dates refer to the time of the Great Migration and the Middle Ages. Some of the slash horizons are dated to the Early Iron Age, the earliest are from the Bronze Age and, presumably, the Neolithic.

Technological Analysis

One of the problems in archaeology of Kazakhstan is the uneven study of the sites belonging to different epochs. For example, in Central Kazakhstan there is a clear bias towards the study of antiquities of the middle and late Bronze Ages, Early Iron Age and Middle Ages. The study of the Stone Age stopped since the 90-es of XX century, the Early Bronze Age is practically not investigated. This article publishes the results of technical-technological analysis of the ceramics of the Grenada camp (Karaganda, Kazakhstan) dated from the late Chalcolithic to the beginning of the Early Bronze Age. Author studied raw materials (three kinds), the clay paste composition (six recipes), the features of the design of the beginning (two programs) and the hollow body. The diversity of pottery traditions, marked for all levels of ceramic production, speaks of the heterogeneous composition of the camp population. The vessels belonged at least to two groups of different origin. Mixed recipes with gruss and grog in the presence of pure demonstrate this process of cultural mixing that took place within the camp. The conclusion is made that the materials of the Grenada camp, including the features of pottery traditions, reflect the complexity of the cultural-historical processes that have taken place in the territory of the Central Kazakhstan in the end of Chalcolithic - in the beginning of Early Bronze Age.

Summary. Background: Prosthetic vascular graft infection (PVGI) is a complication with high mortality. Cyanoacrylate (CA) is an adhesive which has been used in a number of surgical procedures. In this in-vivo study, we aimed to evaluate the relationship between PVGI and CA. Materials and methods: Thirty-two rats were equally divided into four groups. Pouch was formed on back of rats until deep fascia. In group 1, vascular graft with polyethyleneterephthalate (PET) was placed into pouch. In group 2, MRSA strain with a density of 1 ml 0.5 MacFarland was injected into pouch. In group 3, 1 cm 2 vascular graft with PET piece was placed into pouch and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. In group 4, 1 cm 2 vascular graft with PET piece impregnated with N-butyl cyanoacrylate-based adhesive was placed and MRSA strain with a density of 1 ml 0.5 MacFarland was injected. All rats were scarified in 96th hour, culture samples were taken where intervention was performed and were evaluated microbiologically. Bacteria reproducing in each group were numerically evaluated based on colony-forming unit (CFU/ml) and compared by taking their average. Results: MRSA reproduction of 0 CFU/ml in group 1, of 1410 CFU/ml in group 2, of 180 200 CFU/ml in group 3 and of 625 300 CFU/ml in group 4 was present. A statistically significant difference was present between group 1 and group 4 (p < 0.01), between group 2 and group 4 (p < 0.01), between group 3 and group 4 (p < 0.05). In terms of reproduction, no statistically significant difference was found in group 1, group 2, group 3 in themselves. Conclusions: We observed that the rate of infection increased in the cyanoacyrylate group where cyanoacrylate was used. We think that surgeon should be more careful in using CA in vascular surgery.

Abstract. Summary: Background: This pilot study was set up to examine the effects of a continuous postoperative wound infusion system with a local anaesthetic on perioperative pain and the consumption of analgesics. Patients and methods: We included 42 patients in this prospective observational pilot study. Patients were divided into two groups. One group was treated in accordance with the WHO standard pain management protocol and in addition to that received a continuous local wound infusion treatment (Group 1). Group 2 was treated with analgesics in accordance with the WHO standard pain management protocol, exclusively. Results: The study demonstrated a significantly reduced postoperative VAS score for stump pain in Group 1 for the first 5 days. Furthermore, the intake of opiates was significantly reduced in Group 1 (day 1, Group 1: 42.1 vs. Group 2: 73.5, p = 0.010; day 2, Group 1: 27.7 vs. Group 2: 52.5, p = 0.012; day 3, Group 1: 23.9 vs. Group 2: 53.5, p = 0.002; day 4, Group 1: 15.7 vs. Group 2: 48.3, p = 0.003; day 5, Group 1 13.3 vs. Group 2: 49.9, p = 0.001). There were no significant differences between the two groups, neither in phantom pain intensity at discharge nor postoperative complications and death. Conclusions: Continuous postoperative wound infusion with a local anaesthetic in combination with a standard pain management protocol can reduce both stump pain and opiate intake in patients who have undergone transfemoral amputation. Phantom pain was not significantly affected.

SummaryWe have previously shown abnormalities of haemostasis suggestive of intravascular coagulation in patients with malignant hypertension, a condition associated with retinopathy and renal fibrin deposition. To determine whether such abnormalities are specific to malignant hypertension, we have measured several haemostatic and haemorheological variables in 18 patients with malignant hypertension (Group 1), 18 matched healthy controls (Group 2), and 18 patients with non-malignant hypertension (Group 3) matched for renal pathology, blood pressure and serum creatinine with Group 1. Both Groups 1 and 3 had increased mean levels of fibrinogen, factor VIIIc, beta-thrombo- globulin, plasma viscosity and blood viscosity (corrected for haematocrit); and decreased mean levels of haematocrit, antithrombin III and platelet count. Mean levels of fast antiplasmin and alpha2-macroglobulin were elevated in Group 1 but not in Group 3. We conclude that most blood abnormalities are not specific to malignant hypertension; are also present in patients with non-malignant hypertension who have similar levels of blood pressure and renal damage; and might result from renal damage as well as promoting further renal damage by enhancing fibrin deposition. However increased levels of fibrinolytic inhibitors in malignant hypertension merit further investigation in relation to removal of renal fibrin.

AbstractThe purpose of this study is to compare perception of leg length discrepancy (LLD) and clinical results of total knee arthroplasties (TKA) in patients with or without previous ipsilateral hip arthroplasty. Between 2008 and 2015, navigation-assisted TKA was performed in 43 patients with previous hip arthroplasty after hip fracture. After 1:3 propensity score matching was performed, 108 patients of primary navigation-assisted TKA (group 1) and 36 patients with hip arthroplasty (group 2) were included. Knee Society (KS) scores, Western Ontario and McMaster Universities Index (WOMAC) scores, and patients' satisfaction including perception of LLD were evaluated. Radiographic evaluation included mechanical axis, component position, and LLD. Logistic regression analysis was performed to find the factors that affect the clinical outcomes. No significant differences in radiologic and clinical evaluations, except for KS function score, patient's satisfaction and LLD (p< 0.001), were detected between the groups. LLD and its perception were significantly higher in group 2 (1.8 ± 3.4 mm in group 1 and 9.7 ± 4.1 mm in group 2, p = 0.000). Risk factors for the low KS function score were found as LLD (odds ratio [OR]: 1.403, p = 0.008) and previous hip arthroplasty itself (OR: 15.755, p = 0.002), but much higher OR was found in previous hip arthroplasty. Although the outcomes of TKA in patients with ipsilateral hip arthroplasty are comparable to those of primary TKA, LLD was high and patient's satisfaction and functional outcomes were low in patients with previous ipsilateral hip arthroplasty. Care should be taken when considering TKA in patients with previous hip arthroplasty. This is a Level III, case control study.

Background: We evaluated the effects of alpha-1 blocker therapy on clinical and radiological abnormalities in patients of posterior urethral valve with bladder neck hypertrophy. Materials and Methods: A total of 74 patients with posterior urethral valves were seen at our department between 2003 and 2007. Out of these 24 had radiological evidence of bladder neck hypertrophy. Those patients with bladder neck hypertrophy who were seen before June 2006 and did not receive alpha-1 blocker (prazocin) therapy after valve ablation were assigned to group 1 (n=10). Group 2 consisted of 14 age matched patients with bladder neck hypertrophy and comparable prognostic factors who received alpha-1 blocker therapy after valve ablation (n=14). Micturating cystourethrography (MCU) was done periodically and a novel method used to calculate bladder neck hypertrophy. Trends in symptoms and radiological changes were evaluated throughout follow-up. Results: Mean patient age at presentation was 3.02±2.68 years in group 1 and 3.12±3.4 years in group 2. Bladder neck hypertrophy decreased from 2.3±1.0 to 2.0±0.5 in a mean time of 52.0 (34-52) weeks in group 1 where as it decreased from 2.2±0.5 to 1.6±0.3 in a mean time of 32.0 (22-52) weeks. Symptomatically patients in group 2 who received alpha-1 blocker therapy after valve ablation were better and had quick resolution of bladder neck hypertrophy. Conclusions: Use of alpha-1 blocker therapy in patients of posterior urethral valve with bladder neck hypertrophy helps in quick resolution of bladder neck hypertrophy. J Med Sci 2009;12(1):3-7.
