The neutron dose equivalent rate measurements by R3DR/R2 spectrometers on the international space station.

The data from two Bulgarian-German instruments with the basic name "Radiation Risk Radiometer-Dosimeter" (R3D) are discussed. The R3DR instrument worked inside the ESA EXPOSE-R facility (2009-2010), while R3DR2 worked inside the ESA EXPOSE-R2 facility (2014-2016). Both were outside the Russian Zvezda module on the International Space Station (ISS).

[Hemodynamics in the right gastroepiploic artery and its practical application].

Objective: To study functional anatomy of the right gastroepiploic artery (RGEA), its gastric and omental branches and practical significance of these anatomical features.

Material And Methods: We analyzed 20 cadaveric organ complexes (11 men and 9 women, aged 49-85 years) between 2018 and 2019. The organ complexes consisted of the stomach, proximal duodenum and large omentum.

[Lower urinary tract syndrome in elderly and senile people with combined pathology of the prostate and lumbar spine.].

In order to determine the place and role of degenerative changes in the lumbar spine in the pathogenesis of lower urinary tract syndrome and the success of treatment measures, 106 elderly and senile male patients suffering from benign prostatic hyperplasia and spinal pathology were observed. Long-term chronic lower back pain was experienced by 48 (45,3%) patients, 93,8% of them had night urination, 75% had difficulty urinating, and 60,4% had false urge to urinate, which motivated them to contact a urologist.The differences identified using the IPSS questionnaire, respectively 21,78±4,33 and 16,33±4,61 points, indicated a negative value of chronic pain syndrome in the formation of the overall clinical picture of urological pathology.

[Current state of elective surgery for peptic ulcer].

Aim: To analyze the current state of elective surgery for peptic ulcer and to assess its significance for improving the results of treatment of this disease.

Material And Methods: The analysis included elective procedures for peptic ulcer performed in the surgical department of Tula Regional Clinical Hospital in the period from 2011 to 2015. These data were compared with those for the period 1996-2000 in order to objectively identify current changes in surgery for peptic ulcer.

[Features of the clinical picture, diagnosis and treatment of pain syndromes formed on the basis of combined lesions of the spine in the elderly and senile age.].

Based on the long-term observation of 105 representatives of the elderly and senile age, the features of the clinical picture of pain syndromes formed in the elderly and senile age on the basis of combined spinal lesions in osteoporosis and spondylarthrosis are presented, and methods of diagnosis and treatment of such patients are proposed. The main variants of symptoms developing in response to long-term tonic muscle tension in degenerative age-dependent injuries of vertebral bodies, intervertebral discs and facet joints at the level of thoracic and lumbosacral spine are shown. Pathogenetic connections of frequent urination disorders in the elderly and senile age with pathological processes in the spine and muscular-tonic pain syndromes were determined.
