A study is performed of the production of the 178m2Hf isomer (T1/2 = 31 years) upon the neutron irradiation of natural hafnium in a water-moderated reactor with a neutron fluence of ~1022 cm−2. It is shown that the 178m2Hf isomer forms mainly in reactions between fast neutrons and isotopes 178Hf or 179Hf. The specific activity of the isomer in irradiated hafnium is around 2 kBq g−1.

The paper considers the results of long-term observations of megacusp (large-scale shoreline cusps) on the coast of the Gulf of Terpenya (Gulf of Patience), Sakhalin Island. The typical spatial step of the rhythmic forms is about 800 m, and the amplitude of shoreline undulations is 40–50 m. Despite significant changes on time scales of seasons, years, and decades, the main morphological features of the megacusps are preserved for more than 60 years. A model is proposed that explains the evolution of rhythmic shoreline patterns by self-organization of the bottom relief under wave impact. Development of megacusps is shown to be related to the generation of nearshore circulation cells; due to flows within the cells, a small initial perturbation to the shoreline contour can increase over time. A positive feedback between the coastal morphology and hydrodynamics arises when a certain relation is established between the length of the perturbation, the width of the surf zone, and the speeds of nearshore currents. It is concluded that the megacusp system in the Gulf of Terpenya is mainly supported by moderate waves with a significant wave height of ~1.6 m. [ABSTRACT FROM AUTHOR]

The article presents a case of a surgical treatment of removing a dermoid cyst of the floor of the oral cavity in a patient with severe hemophilia A. A detailed analysis was carried out of the surgical operation, postoperative management, coagulation factor replacement therapy and accompanying therapy, as well as the features of anesthesia, which allowed a surgical intervention without any hemorrhagic and infectious complications.

Objective: Evaluation of efficacy and clinical safety of ethylmethylhydroxypyridine malate (Ethoxidol) in cerebrovascular disease in out-patient, and in-patient setting., Material and Methods: In the observational study was included of the 70 patients (aged 62.84±6.54 y.o) diagnosed with unspecified cerebrovascular disease, hypertensive encephalopathy, atherosclerosis of cerebral vessels. To access neurological deficit Montreal Scale (MoCA test) was used, MFI-20 test for asthenia. Berg balancing (BBS-test), tinnitus severity score (THI), and general clinical condition score also were recorded. Quality assurance was evaluated by VAS, and EQ-VAS Scores (European life quality gr). Interventions were identical, except treated received Ethoxidol 200 mg IV once/day, or 200 mg IM once/day and 200 mg per os (400 mg/day) during 7 days, follow up by oral administration of Ethoxidol 600 mg/day (200 mg TID) for the period of 53 days., Results: The results of the observational study has shown of high clinical efficacy and tolerability of the Ethoxidol therapy. Statistical significance between baseline and treatment period was recorded on the 7th and 60th day of observation ( p <0.001). Stabilization of the archived condition persisted on the 60 th day. Ethoxidol administration reduced asthenia cognitive dysfunction, dizziness, balance disorders, and tinnitus. CGI Score revealed reduction of the severity of patient's condition and total of clinical improvement; EQ-VAS Score showed growth of quality of life. The majority of patients were satisfied with performed therapy, attending physicians highlight Ethoxidol safety. Serious adverse events weren't recorded., Conclusion: Ethoxidol was considered as efficient and safe medication for in-patient and out-patient treatment of patient with cerebrovascular diseases (chronic cerebral ischemia).

The paper presents a clinical case demonstrating difficulties in differential diagnosis of salivary glands disorders. The patient underwent several surgical procedures none of which was indicated. The article summarizes the reasons for diagnostic pitfalls of the case.

The authors with the goal of postoperative dynamic control over the results of surgical treatment of patients previously operated for salivary stone disease and various ducts deformations of the parotid salivary glands examined 16 patients with an observation period up to 8 years. It was found that recurrent acute parotitis or recurrence of stone formation was observed in 100% of cases. The authors developed methods of surgical treatment leads to long-term clinical success with no recurrence of the disease.

The authors conducted an analysis of the efficiency of the method of suandokmai for diagnosis and treatment of diseases of the salivary glands. The use of calendarscope allows to establish the absence of stone in the case of salivary colic. In rare cases it is possible to remove the stone without surgical intervention at small dimensions of the calculus. 'Price of equipment - the efficiency of diagnosis and treatment' does not allow to recommend the method in clinical practice.

Aim: To determine the efficacy of post-stroke dysphagia treatment by choline alfoscerate (ChA), succinate combination (SC), and their combination with sip, larynx, and swallowing exercises., Material and Methods: Four groups of primary ischemic stroke (IS) patients (n=80; 62±0.2 y.o., verified by MRI), including controls, admitted to Stroke Unit 24 h after stroke in the area of RAM (29.5%), and LAM (70.5%), were studied. Basic therapy was provided according to National Stroke Treatment Recommendations, treated groups received ChA 14 mg/kg (2 st gr.), SC 0.5 mg/kg (3 nd gr.), combination of two compounds (3 d gr.). Controls (4 th gr.) received placebo. Pharmacological treatment was provided for 10 days with continuation by oral administration. Dysphagia was measured semi-quantitively by MASA scale, three scale determinants were measured on admission, on 5 and 13 days of stay in the hospital., Results and Conclusion: The differences were significant and observed on the 5 th day of treatment. ChA mostly improved sip control, and larynx movements (38% above controls; p<0.01), while SC improved the closure of vocal cords (55% above controls; p<0.01). This may reflect the differences in synaptic control of these functions. Combined treatment was more effective than monotherapy: 15% above ChA, and 21% above SC for swallowing function (p=0.01); 33 and 22% for vocal closure, 37% (p=0.05) and 76% (p=0.01) for larynx movement, which may be due to synergism between two medications. Therefore, sip, larynx, and swallowing exercises with pharmacological support of ChA and SC ameliorated dysphagia after IS.
