The Radochowska Cave is known primarily from the find of a cave bear skull, intended to be placed intentionally by Palaeolithic hunters in a 'stone cage'. This find was supposed to be proof of the existence of the cult of bear hunters at this site. Critical analysis did not give a clear answer to its occurrence or a clear negation of this phenomenon. Research is not facilitated by the fact that a large part of the collection was lost after World War II. The found part, especially numerously represented by predatory mammals, made it possible to verify the old lists of fauna and extend them with a number of new species, often unknown from the Polish Sudetes, such as Cuon alpinus europaeus or Panthera pardus. The analysis showed the presence of two main faunistic associations. The older one, dated to MIS 3, is represented by a number of cold-loving forms. Remains of Holocene species and those from the very end of the last glaciation represent the second faunal assemblage. [ABSTRACT FROM AUTHOR]

Summary: Adults with obesity exhibit a restrictive pattern, whereas children with obesity exhibit an obstructive pattern. However, the transition process remains unclear. We performed a systematic search for studies reporting on body mass index and pulmonary function in children. The main outcomes were forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), and their ratio (FEV1/FVC). We compared individuals with overweight or with obesity with individuals with normal weight. Random‐effects models were used to calculate pooled estimates. A total of 17 studies were included. Individuals with obesity had a lower FEV1/FVC ratio (mean difference [MD] = −3.61%; 95% confidence interval [CI] = −4.58%, −2.64%) and a higher percent‐predicted FVC (MD = 3.33%; 95% CI = 0.79%, 5.88%) than those with normal weight. Obesity impaired pulmonary function in the obstructive pattern during childhood to young adulthood, and the maximum obstruction was observed at the age of 16 years in boys and 20 years in girls. The effects attenuated at approximately 30 years and then shifted to the restrictive pattern after 35 years of age in men and 40 years in women. The effects of obesity on pulmonary function change from the obstructive pattern in childhood to the restrictive pattern in adulthood. [ABSTRACT FROM AUTHOR]

The analyzed specimen was found in the 1930s by Zotz, in Wschodnia cave (German name Hellmichhöhle, now W Sudeten Mts, Poland). Currently, it is housed in the Archaeological Museum of Wrocław. It is a well preserved splanchnocranium with teeth of an adult Eurasian brown bear. Integral part of the skull is also an intact mandible. Several postcranial skeletal bones were also found for this specimen, including one rib with a human-drilled hole. For the above-mentioned specimen, three C14 datings were made using the AMS method. All three dates gave similar results, allowing the age of the find (after calibration) to be estimated at 14.8-13.8 KY BC, i.e. the Bølling phase of relatively older Dryas. Taxonomic assignation, based on the morphometrical analysis, was confirmed by DNA analysis. It represents subclade 1b, recently identified in Carpathian Mts. The degree of wear of his tooth crowns, especially his incisors and canines, is remarkable, which is completely inadequate to the wear of the remaining teeth and to the individual's age. German researchers suggested that the procedure was performed by a human for ritual purposes. However, the anthropological nature of this find was questioned by Polish researchers, who said that the process was natural and that the abrasion of the front teeth was the result of a malocclusion. Our analyses confirm the earlier assumptions of German scientists that the pathologies visible on the teeth are the result of anthropogenic effects, which was the aim of our research. It is also indirect evidence of the presence of Homo sapiens in the Late Pleistocene of the Sudeten areas of Poland. [ABSTRACT FROM AUTHOR]

In the St. Nicholas Church archaeological site (Libkovice, Czechia; the 18th century cemetery) a female skeleton with a stone object in the left iliac fossa was found. It was a cyst-like structure. The measures of it were 54 mm in length and 35 mm in maximum diameter. Within the object fetal bones (long bones, i.e. femur and two tibias, two scapulas, three ribs, vertebrae and other tiny bone fragments) were revealed. The methods used for the analysis were intended to describe the external and internal morphology of the object and its content: X-ray, CT imaging, SEM, histological staining and EDS. The EDS analysis revealed the presence of primarily oxygen, calcium and phosphorus in bone samples, and oxygen and silicon, in stone shell. The measurements of the femur (20.2 mm) and tibia (16 mm) shafts allowed to estimate the fetal age as the 15-18 week of pregnancy. During the differential diagnosis three most likely cases were taken into account: fetiform teratoma (FT), fetus-in-fetu (FIF) and lithopedion. FT was excluded due to the presence of long bones and their proportions, and due to the presence of an anatomically correct spine. Of the other two possible variants, fetus-in-fetu is more likely than lithopedion, due to the lack of a skull, better development of lower limbs, and low calcium content in the shell. The results do not allow to clearly answer the question which of these two cases is the object due to the insufficient number of similar discoveries in the excavation material. [ABSTRACT FROM AUTHOR]
