Management And Conservation

Wildlife management is predicated upon the use of scientific research to assist decision-making. However, assessment of the effectiveness of the management–research relationship is rarely undertaken. Polar bears (Ursus maritimus) have benefitted from an international agreement that required each of the countries within the species’ range to manage them using the best available scientific data. The objective of this paper is to conduct a systematic review of peer-reviewed literature on polar bears to describe research trends and to assess how effectively research has met management needs. We analyzed 1191 peer-reviewed scientific papers from 1886–2016 covering 24 research topics. Annual counts of papers within each research topic were assessed for temporal trends, spatial coverage, and the extent to which they have facilitated management and monitoring needs. The annual number of papers increased from <10 in the early 1960s to >50 in recent years with a mean of 2.2 papers per subpopulation per year with great variation between the 19 global subpopulations. We conclude that there is an imbalance in the geographic and thematic focus of peer-reviewed research in recent years, and that only four subpopulations appear to have had a research focus covering most parameters essential for conservation and sound management.

Abstract We examined the surgical outcomes of minimally invasive percutaneous nephrolithotomy (MPCNL) in scoliotic patients with complicating urolithiasis. Two patients with scoliosis were hospitalized for MPNCL due to upper tract urolithiasis. Calyx puncture was performed in the prone position under ultrasonographic guidance. The renal access route was established using a set of 8F to 16F dilators, and a transpyelic ballistic lithotriptor was used to fragment the calculi. The stone burdens in the 2 patients were 410 mm2 and 500 mm2. The entire operative time was 40 to 70 minutes, and the mean time of establishing percutaneous access was 20 minutes. The calculi were completely removed by single-session pneumatic lithotripsy. The 2 patients recovered from MPCNL uneventfully, and the follow-up radiologic examinations identified no stone residual or recurrence. MPCNL is a minimally invasive modality that is effective and safe for the treatment of urolithiasis in patients with scoliosis.

Abstract. Considering research on rehabilitation and rehabilitation potential in modern medical and psychological literature from the leading databases reduces subjectivity when analyzing the relevance of scientific issues. The results obtained will allow predicting the further advancement of scientific knowledge on rehabilitation and rehabilitation potential. Materials and methods. The criterion for inclusion in the review was scientific data published in peer-reviewed scientific journals and lack of repetition of data from the same scientific papers by the same authors. Results. When searching for the word “rehabilitation” over the past 10 years, 3685 works were found in the Web of Science database, and 36332 publications were found in the eLibrary national database. A search for the keyword “rehabilitation potential” in the Web of Science database using inclusion/exclusion criteria revealed 3569 published works while a comparable search query in the domestic database identified 786 works. When comparing the Web of Science and eLibrary databases, similarities and differences were revealed in relation to the use of the concepts of “rehabilitation” and “rehabilitation potential”. The “Neurology” direction occupies a leading position in both databases, “Rehabilitation” as a separate direction is mostly studied abroad, and psychological assistance closes the top three in the Web of Science database. Mental health rehabilitation issues are more commonly presented in eLibrary. Conclusion. The development and publication of studies on rehabilitation potential is more active when it comes to patient-oriented or non-medical models of rehabilitation. Verification of this assumption may be the subject of further research.

The Face

About 400 years before the birth of Christ, near Mt. Lyscabettus in ancient Greece, the pale orb of the sun rose through the mists. According to habit, Meton recorded the sun’s location on the horizon. In this era when much remained to be discovered, Meton hoped to find predictable changes in the locations of sunrise and moonrise. Although rainy weather had limited his recent observations, this foggy morning he discerned specks on the face of the sun, the culmination of many such blemishes in recent years. On a hunch, Meton began examining his more than 20 years of solar records. These seemed to confirm his belief: when the sun has spots, the weather tends to be wetter and rainier. Theophrastus reported these findings in the fourth century B.C. Other ancient accounts concerning the sun and weather are vague. If one stretches one’s imagination, some comments by Aratus of Soli, Virgil, and Pliny the Elder may touch on this subject. What happened to the original records used by Theophrastus? Perhaps these and related scientific data were burned in the fire that destroyed the Library at Alexandria around A.D. 300. Other possible ancient accounts have vanished. Two thousand years passed. The Roman Empire rose and fell, the Dark Ages lasted a thousand years, and Europe entered the Renaissance. The 1600s reveal perhaps half a dozen scattered references to changes in the sun and their effect on weather. After a few more references in the 1700s, scientific interest in the sun waned. Following Sir William Herschel’s comments on sunspots and climate in 1796 and 1801, about 10 scientific papers touched on the sun’s influence on climate and weather. The next two decades contain about 10 or so references to this topic. Shortly after a paper by C. Piazzi Smyth appeared in the proceedings of the Royal Society in 1870, the field exploded. This paper stimulated scientists such as Sir Norman Lockyer, Ferguson, Meldrum, and others to think about solar and terrestrial changes. Meldrum, a British meteorolo gist in India, considered Indian cyclones. His tabular values are compared with sunspot numbers in Figure 1.1.

Percutaneous Nephrolithotripsy

The article presents the experience of treating patients with urolithiasis in the urological clinic of the Aleksandrovskaya hospital. Due to the improvement of technologies, the number of minimally invasive surgeries such as contact ureterolithotripsy, percutaneous nephrolithotripsy and percutaneous nephrolitholapaxy has increased significantly. Performing open surgical interventions is indicated only in complicated cases such as the presence of purulent calculous pyelonephritis. The indication for contact ureterolithotripsy is the localization of concretions in the pelvic ureter, as well as long-term (more than 4 weeks) presence of concretions in any part of the ureter. Percutaneous nephrolitolapaxy is the method of choice in the treatment of urolithiasis in case of uninfected kidney stones smaller and larger than 20 mm in diameter, especially in elderly patients. Emergency contact lithotripsy is indicated for treatment of acute serous obstructive pyelonephritis caused by concretion of any localization. When stones locate in lower calices of kidney effective method is percutaneous nephrolitholapaxy.

Urolithiasis ranks second among urological diseases, after inflammatory processes, and first among surgical interventions in urological hospitals. The problem of this disease treatment is a long-term rehabilitation and disablement, which entails a significant increase in costs and requires changes in the tactics of treatment of patients. Since its introduction until today, percutaneous nephrolithotomy (PCNL) is the standard treatment for nephrolithiasis with a stone size of more than 1.5–2.0 cm. In its standard version, PCNL ends with the placement of nephrostomy catheter through the formed parenchymal channel, but there are techniques of the surgery completion either without nephrostomy catheter with a JJ stent – tubeless PCNL, or without nephrostomy and JJ stent at all – totally tubeless PCNL. However, nowadays, the use of tubeless and totally tubeless techniques is one of the most controversial topics in percutaneous nephrolithotomy in terms of safety and efficacy in their application. Aim. To analyze the results and safety of percutaneous nephrolithotomy by means of tubeless and totally tubeless techniques based on scientific evidence. Analysis of the scientific literature shows that tubeless and totally tubeless PCNL techniques are a safe method of percutaneous surgery and their application reduces pain and analgesic requirements in the postoperative period, shortens the length of postoperative hospital stay, and enhances recovery after surgery in patients, therefore resulting in cost-saving treatment. Conclusions. Tubeless and totally tubeless PCNLs are recommended for widespread use in urological practice, but it is worth to mention that these techniques should be performed in selected patients and by an operating surgeon with significant experience in percutaneous surgery.

Percutaneous Nephrolithotripsy

The problem of urolithiasis remains one of the key in modern urology today. Urolithiasis, its recurrent nature, often-severe complications and invalidation of patients has a high medical and social significance. Recently, more and more urolithiasis occurs in oblique and aging years and is usually accompanied by a serious accompanying somatic pathology, which is characterized by significant violations. The latter, on the one hand, may be a risk factor for the development of urolithiasis, but on the other requires a careful approach to the choice of therapeutic tactics. Improvement of endoscopic equipment contributed to the active introduction of noninvasive methods of surgical treatment of nephrolithiasis in the clinical practice. The “golden” standard for the removal of large and cortical stones is, today, a transdermal nephrolithotripsy. The staff of the clinic of the Institute of Urology of the National Academy of Medical Sciences of Ukraine has a wealth of experience in the use of this method in the treatment of urolithiasis. The purpose of the work is to determine the effectiveness of percutaneous nephrolithotripsy in the treatment of nephrolithiasis in both kidneys, accompanied by severe comorbidity. The patient conducted general-clinical and biochemical tests of blood and urine, X-ray methods of examination, ultrasound examination of the abdominal cavity, MSCT. In the presented clinical observation in the patient, nephrolithiasis of both kidneys was diagnosed, accompanied by severe concomitant somatic pathology. Percutaneous nephrolithotripsy allowed two steps to remove all concrements, which once again proved the success of this method in the treatment of urolithiasis.

Insectivorous Plants

Carnivorous plants have fascinated botanists, evolutionary biologists, ecologists, physiologists, developmental biologists, anatomists, horticulturalists, and the general public for centuries. Charles Darwin was the first scientist to demonstrate experimentally that some plants could actually attract, kill, digest, and absorb nutrients from insect prey; his book Insectivorous Plants (1875) remains a widely cited classic. Subsequent monographs by Lloyd (1942) and Juniper et al. (1989) summarized and synthesized available scientific data on these remarkable plants. Scientific investigations and understanding of carnivorous plants has evolved and changed dramatically in the nearly 30 years since Juniper et al’s Carnivorous Plants was published, and thousands of scientific papers on carnivorous plants have appeared in the academic literature. In putting together this fourth major work on the biology of carnivorous plants, Ellison and Adamec have assembled the world’s leading experts to provide a truly modern synthesis. The contributing authors examine every aspect of systematics, physiology, biochemistry, genomics, ecology, and evolution of what Darwin called ‘the most wonderful plants in the world,’ and describe the serious threats they now face from over-collection, poaching, habitat loss, and climatic change, which directly threaten their habitats and continued persistence in them. This accessible text is suitable for senior undergraduates, graduate students, and researchers in plant biology, ecology, and evolutionary biology. It will also be of relevance and use to horticulturalists and carnivorous plant enthusiasts.

SynopsisThis brief biography summarizes the life of Scots-born Robert Kidston (1852–1924), who was arguably the best and most influential palaeobotanist of his day. In over 180 scientific papers he laid the foundations for a modern understanding of the taxonomy and palaeobiology of Devonian and Carboniferous plants. His expertise was critical to the research and curation of the Geological Survey and British Museum (Natural History) and excavations of Glasgow's Fossil Grove introduced the great Carboniferous forests into the public imagination. Despite their age, his meticulously documented collections of slides (deposited in the Botany collection University of Glasgow) and hand specimens and notebooks (deposited in the collections of the British Geological Survey, Nottingham) provide a wealth of important scientific data with modern applications in plant taxonomy, biostratigraphy and palaeoclimatic reconstruction.
