This article discusses the issues of choosing a treatment method for proximal humerus fractures and how the proposed minimally invasive method of osteosynthesis for fractures of the proximal humerus allows less traumatic repositioning of bone fragments andmore stable fixation of bone fragments. A less invasive osteosynthesis method for fractures of the proximal humerus allows less traumatic repositioning of bone fragments and more stable fixation of bone fragments. Improve treatment results by developing aminimally invasive method of extramedullary treatment for fractures of the proximal humerus.. This research work was carried out in clinical bases of RITOIAM and RSHTYoIM Bukhara branch in patients with multiple fragment fractures of the proximal part of the shoulder bone with 40, 15 of which were found to be moved in the varus state of the bone fragments. Patients were divided according to gender and 15 were male and 25 were female. The duration of the trip was an average of 5,8±1,8 days (3 –7 days). In order to assess the status of bone fragments in multi –fragment fractures in patients, the classification of Neer (1970) was used: single –fragment, 10 (25%) –two-fragment, 12 (30%) -three-fragment and the remaining 12 (30%) -multiple-fragment fractures in 6 (15 %) patients. In shoulder bone proximal fractures, osteosynthesis was performed with a less invasive blocking plate through an external distraction apparatus developed in the clinic and a small-sized wound incision.

We are conducting a clinical study of the use of allogeneic polydactyly-derived chondrocyte sheets (PD sheets) for the repair of articular cartilage damage caused by osteoarthritis. However, the transplantation of PD sheets requires highly invasive surgery. To establish a less invasive treatment, we are currently developing injectable fragments of PD sheets (PD sheets-mini). Polydactyly-derived chondrocytes were seeded in RepCell™ or conventional temperature-responsive inserts and cultured. Cell counts and viability, histology, enzyme-linked immunosorbent assay (ELISA), quantitative real-time polymerase chain reaction (qPCR), and flow cytometry were used to characterize PD sheets-mini and PD sheets collected from each culture. To examine the effects of injection on cell viability, PD sheets-mini were tested in four experimental conditions: non-injection control, 18 gauge (G) needle, 23G needle, and syringe only. PD sheets-mini produced similar amounts of humoral factors as PD sheets. No histological differences were observed between PD sheets and PD sheets-mini. Except for COL2A1, expression of cartilage-related genes did not differ between the two types of PD sheet. No significant differences were observed between injection conditions. PD sheets-mini have characteristics that resemble PD sheets. The cell viability of PD sheets-mini was not significantly affected by needle gauge size. Intra-articular injection may be a feasible, less invasive method to transplant PD sheets-mini.

Co2 Gas

CO2 gas with a special isotopic signature (δ13C = −35.2‰ vs. VPDB) was used as a marker to evaluate the efficiency of a drinking water treatment method and the effect of an ultrasonic (US) stirrer. This treatment was developed to prevent precipitation and corrosion effects in water–supply systems. The research work was performed using a laboratory-scale pilot plant that was filled with tap water. The stable isotope analyses of δ13C-DIC (Dissolved Inorganic Carbon) in the water samples indicated that the maximum content of added CO2 gas in DIC was in the range of 35 to 45%. The use of the US stirrer during the entire experiment decreased the method's overall efficiency by 10%, due to degassing at a late stage of the experiment but accelerated the dissolution process in the early experimental stage.

Functional Autonomy

At present, patients with recurrent nodular goiter account for a significant portion of patients operated on for nodular goiter. At the same time, the comorbid background characteristic of this age group and the technical difficulties of the intervention on cicatricial tissues of the neck cause a high risk of complications of the operation, 3–7 times higher than with primary thyroid interventions. The aim of the study was to evaluate the effectiveness and safety of treatment of recurrent nodular goiter using an alternative minimally invasive method — sclerotherapy. The study included 30 patients previously operated on for nodular goiter. All had 4 courses of sclerotherapy, each included 5 sessions with a frequency of 1 session per week, followed by a follow-up period of 3 months. Polydocanol was used as a sclerosant. The analysis showed that sclerotherapy for recurrent nodular goiter allows all patients to reduce recurrent nodular formations, and in almost a third of cases, complete reduction of the nodes. On average, the decrease in the volume of thyroid residues was 9.6 ± 1.5 ml, and the size of nodular formations decreased by 17.2 ± 1.3 mm (3.7 times — from 23.6 ± 1.4 mm to 6.4 ± 0.7 mm, P <0.001). Nodes more than 3 cm, initially 19 %, ceased to be detected after the third course of sclerotherapy. In all cases, managed to eliminate hormonal imbalances in patients who initially had functional autonomy, as well as signs of compression of the neck organs. At the same time, sclerotherapy of nodules of the thyroid gland using polydocanol as a sclerosant is a safe minimally invasive treatment method, is not accompanied by severe pain and the risk of hypoparathyroidism and laryngeal paresis.

Stored Information

Libraries are widely used by government, universities, research institutes, and the public since they are storing and managing intellectual assets. The library information directly stored in libraries and about the people interaction with libraries can be transformed into accessible data which then will be used by researchers to help library better serve users. Librarians need to understand how to transform, analyze, and present data in order to facilitate such knowledge creation. For example, the challenges they face include how to make big datasets more useful, visible and accessible. Fortunately, with new and powerful analytics of big data, such as information visualization tools, researchers/users can look at data in new ways and mine it for information they intend to have. Moreover, interaction of users and stored information has been taken into librarian's consideration to improve library service quality. In this work, the authors discuss the characteristics of datasets in library and argue against a popular confusion that data involved in library research is not big enough, conduct a review for the research work on library big data and then summarize the applications and research directions in this field. The status of big data research in library in China is discussed. The challenges associated with it are also discussed and explored.

The Subject

Objective The aim of this study was to evaluate epoxy-pin external skeletal fixation technique for the treatment of open fractures in calves and foals. Study Design Twenty-eight calves and four foals (weighing 45–105 kg) with fractures distal to the stifle or elbow made the subject for the retrospective study. The pins (2.0–3.0-mm Kirschner wires, crossed at 60–90°) were fixed at least at two locations in both proximal and distal bone fragments as per the case situation. The pins in the same plane were bent (∼2 cm from the skin) towards the fracture site or joint and were joined using an adhesive tape (additional pins used when required) to make a temporary scaffold of connecting bars or rings. Thoroughly mixed epoxy putty was applied along the pin scaffold (the epoxy columns were 20–25 mm diameter) and allowed to set for 45 to 60 minutes. All animals were evaluated based on various clinical and radiographic observations made at regular intervals. Results The epoxy-pin fixation was easy to apply and provided stable fixation of bone as indicated by early weight bearing, and fracture healing within 45 to 60 days (17/32 cases). The functional recovery was good to very good in 14 animals and satisfactory in nine cases by 12 months after removal of the fixator. Conclusions The multiplanar epoxy-pin external skeletal fixation provides stable fixation of unstable open fractures distal to the stifle or elbow joint; hence, it can be used to treat a variety of fractures in calves and foals weighing up to approximately 100 kg, especially open infected fractures of lower limb, which are difficult to treat by conventional techniques.
