Neolithic Pottery

The paper publishes the long-term study results of the Early Neolithic population pottery technology in the Lower, Middle and Upper Don Region. This research was carried out within the framework of the historical and cultural approach by the method of A.A. Bobrinsky. It was based on binocular microscopy, traceology and experiment in the form of physical modeling. 483 samples of ceramics (conditionally separate vessels) were subjected to techno-technological analysis. They originate from the cultural layers of the Rakushechny Yar camp (294) and I Razdorskaya site (4), located in the Lower Don region, as well as 14 sites of the Middle and Upper Don Region containing Karamyshev type ceramics (185). The authors give a general description of the Early Neolithic pottery of the Don region and a comparative analysis of the data on pottery technology of the Lower, Middle and Upper Don Region population. The problems of the origin and distribution of early Neolithic pottery traditions are considered, the similarities and differences in the neolithization process in the Don region and the Volga region are distinguished.

Technological Analysis

The paper contains the results of the technical and technological analysis of ceramics from the Eneolithic layers of the Rakushechny Yar settlement. It is located on the Porechny Island (the Don River, Rostov Region, Russian Federation). The methodological basis of the conducted research is a historical and cultural approach to the study of ancient ceramics, developed in Russian archeology by A.A. Bobrinsky. The methods of the research are binocular microscopy, trasology and experiment (physical modeling). 141 samples of ceramics (conditionally separate vessels) from layers 5-2 of Rakushechny Yar were subjected to a microscopic examination. The obtained technological information allowed us to reconstruct techniques and methods of Eneolithic utensils manufacturing at all stages of production - preparatory, creative and fortifying stages of pottery technology. Based on these data, the paper presents a general description of the Eneolithic pottery. A comparative analysis was made of the pottery technology of the Neolithic and Eneolithic population that inhabited the Rakushechny Yar site. According to its results, the similarities and differences of the Eneolithic and Neolithic pottery traditions are highlighted. Particular attention is paid to the question of the possible origins of new traditions, which became widespread during the Eneolithic. These include silty clays selection traditions, the introduction of artificial additives into the molding composition: crushed shell, bird fluff and sand.

Background. Although various devices have been clinically used for laparoscopic liver resection (LLR), the best device for liver parenchymal transection remains unknown. Olympus Corp (Tokyo, Japan) developed a laparoscopic hybrid pencil (LHP) device, which is the first electric knife to combine ultrasound and electric energy with a monopolar output. We aimed to evaluate the feasibility of using the LHP device and to compare it with the laparoscopic monopolar pencil (LMP) and laparoscopic ultrasonic shears (LUS) devices for LLR in a porcine model. Methods. Nine male piglets underwent laparoscopic liver lobe transections using each device. The operative parameters were evaluated in the 3 groups (n = 24 lobes) during the acute study period. The imaging findings from contrast-enhanced computed tomography and histopathological findings of autopsy on postoperative day 7 were compared among groups (n = 6 piglets) during the long-term study. Results. The transection time was shorter ( P = .001); there was less blood loss ( P = .018); and tip cleaning ( P < .001) and instrument changes were less often required ( P < .001) in the LHP group than in the LMP group. The LHP group had fewer instances of bleeding ( P < .001) and coagulator usage ( P < .001) than did the LUS group. In the long-term study, no postoperative adverse events occurred in the 3 groups. The thermal spread and depth of the LHP device were equivalent to those of the LMP and LUS devices (vs LMP: P = .226 and .159; vs LUS: P = 1.000 and .574). Conclusions. The LHP device may be an efficient device for LLR if it can be applied to human surgery.

Abstract Background Long-term safety, pharmacokinetics, and efficacy of open-label golimumab therapy in children with moderate–severe ulcerative colitis were evaluated. Methods Week-6 golimumab responders (Mayo score decrease of ≥30% and ≥3 points from baseline, rectal bleeding subscore of 0/1 or ≥1 decrease from baseline) entered the long-term extension at week 14 and received maintenance therapy (subcutaneous, q4w). Patients ≥45 kg could receive at-home treatments at week 18. Pharmacokinetic, safety, and efficacy results were summarized through week 126 (2 years). Results Among 35 enrolled children, 21 (60%) responded at week 6 and 20 entered the long-term extension (median age of 14.5 years and median weight of 46.1 kg). Eleven of 20 patients (55%) completed 2 years of treatment. No anaphylactic or serum sickness-like reactions, opportunistic infections, malignancies, tuberculosis, or deaths occurred. The safety profile of golimumab from weeks 14 through 126 and that observed through week 14 was generally consistent. Median trough golimumab concentrations in evaluable patients were consistent from weeks 14 (1.39, interquartile range 0.67–3.60) through 102 (1.18, 0.78–2.16), but higher at week 110 (4.10, 1.30–4.81). The incidence of antigolimumab antibodies increased from 10% (2/20) at week 30 to 25.0% (5/20) at week 126; 1 patient had neutralizing antibodies. At week 110, 50% (10/20) of patients were in remission (ie, Pediatric Ulcerative Colitis Activity Index &lt;10). Among all enrolled patients, 28.6% (10/35) achieved remission at week 110. Conclusions Among children with ulcerative colitis who initially responded to golimumab induction and received q4w maintenance treatment in the long-term extension, 50% showed continued clinical benefit through 2 years. No new safety signals were observed.

Study Abroad Program

Much attention has been paid to the effects of study abroad, especially because of recent increases in participation in such programs. One problem, however, is the selection bias of participants inherent in study abroad programs. The present study examines whether participation in a short-term study abroad program leads to participation in further long-term study abroad programs. Data were obtained from 705 applicants in the 2013-2015 academic year at a Japanese university, 300 of whom were assigned randomly to participate in a short-term study abroad program. The study results showed a significantly higher participation rate among previous participants than among nonparticipants. The results of a questionnaire completed by the former participants of the short-term program showed that they were more likely to translate plans for participating in the long-term study abroad program into action based on their prior overseas experiences.
