The name Flexopecten glaber ponticus (Bucquoy, Dautzenberg & Dollfus, 1889) is generally used for the only Pectinidae representative inhabiting the Black Sea. It is registered in the Red Book of the Republic of Crimea as endemic subspecies reducing in amount. F. glaber ponticus is listed in WoRMS MolluscaBase as the only accepted subspecies of Flexopecten glaber (Linnaeus, 1758). In the past its taxonomic status has been changed from a geographic variety to valid species. The purpose of this study is to establish its correct taxonomic status. The study is based on a comparative analysis of conchological features of Flexopecten glaber and F. glaber ponticus in relation with the brief natural history of population in the Black Sea. Sampling was performed by snorkel equipment in Kazach’ya Bay (Black Sea, Crimea, Sevastopol) at 2–6 m depths. A total of 100 scallop specimens were sampled in September 2017. To assure a better understanding in a broader context those results are compared with the previously published morphological data based on the analysis of a large amount of material from the Black Sea and the Mediterranean Sea – Marmara Sea regions. Comparative analysis of conchological features of F. glaber ponticus from the Black Sea with F. glaber from the Mediterranean region has not revealed any distinct differences between them. Thus, there are no evidenced data for the diagnosis of F. glaber ponticus as a subspecies. Species F. glaber appeared in the Black Sea not earlier than 7,000 years ago and formed a well developed population less than 3,000 years ago. We have to conclude that the specified divergence period is not long enough to form a subspecies. As a result of the present survey the subspecific status of F. glaber ponticus is not retained and the name is placed in synonymy of the parent species Flexopecten glaber.

The three European countries included in the northwest littoral of the Mediterranean region – Italy, France and Spain – reported their first cases of the SARS-CoV-2 coronavirus early in 2020. The subsequent epidemic strongly impacted these countries, challenging the healthcare systems efficiency, and the capacity and transparency of their public statistics structures. Because public statistics were not fully adapted to such a new health situation, the available official data could not wholly describe the epidemic correctly. This paper developed an indicator derived from the prevalence of SARS-CoV-2 aiming to describe the time and spatial dynamics of the epidemic. Although the analysis was not applied to France due to the lack of data available, the comparative analysis among Spain and Italy highlighted some similarities and certain divergences, partially attributable to the features of each country‘s national demographic patterns and the peculiarities of applied health protocols. Finally, mortality during the first wave of the epidemic has been analysed for the three countries, demonstrating higher mortality index in Spain, although the reported number of SARS-CoV-2 declared deaths does not explain a portion of this mortality excess.

After the fall of the Meroe kingdom, three entities – Nobadia, Early Makuria, and Alwa (Alodia) – emerged in northeast Africa between the 4th and the 6th centuries AD. Richly furnished elite cemeteries with tombs of the Nobadian kings are known from Qustul and Ballaña in Lower Nubia (Emery and Kirwan 1938), but until now no royal tombs of Early Makuria have been identified. A comparative analysis of some recently excavated adornments and ornaments from the tumulus cemetery of el-Zuma in Upper Nubia have now enabled the Early Makuria royal tombs (AD 450–550) to be placed there. The assemblages from three large tumuli are dominated by personal adornments (beads, pendants, earrings, chains, crosses, and a ring), royal regalia (cabochons and settings), and other decorated items (metal sheets, an intarsia and ivory gaming pieces). Apart from beads of various materials, like marine mollusk shell, ostrich eggshell, faience and stone, which were made probably in local workshops, the remaining items were imports from the Mediterranean and Sri Lanka/South India (glass beads in the latter case). Moreover, many of the decorated objects and the techniques used to make them find parallels in the elite Nobadian cemeteries of Qustul and Ballaña, hinting at the royal origin of some of the Early Makuria tomb owners at el-Zuma. These parallels induce the thought that there was a single workshop in late antique Nubia producing artifacts for the elite.

Introduction: Caloric restriction is the only well‍‑documented nutritional intervention prolonging the life of mammals. This method modifies the lipid levels in blood, controlling obesity and delaying the onset of many medical conditions associated with metabolic disorders. The aim of the study was to carry out a comparative analysis of lipid profile in patients on Mediterranean or CRON (Caloric Restriction with Optimal Nutrition) diets, before and after six weeks of dieting.Material and methods: The following parameters were compared: total cholesterol, total lipids, triglycerides, LDL cholesterol, HDL cholesterol, and BMI. Additionally, we measured the levels of insulin, HOMA score, and anthropometric parameters. The comparative analysis demonstrated a statistically significant correlation between mild caloric restriction and blood lipid profile.Results from studies on patients who underwent six­‍‑week dietetic intervention indicated statistically significant changes in biochemical parameters due to caloric restrictions. Such changes were not found in subjects following the Mediterranean diet. The greatest decrease in the blood level of triglycerides was found in subjects on the CRON diet, LDL cholesterol, total cholesterol and total lipid levels also decreased. No significant changes if biochemical parameters were found in patients on the Mediterranean diet.Conclusions: A comparative analysis of all parameters demonstrated that the use of mild caloric restrictions with ensured supply of all necessary nutrients seems to be the most effective solution for reducing fatty tissue.
