- Objective: Circadian rhythm disruption is commonly observed in bipolar disorder (BD). Daylight is the most powerful signal to entrain the human circadian clock system. This exploratory study investigated if solar insolation at the onset location was associated with the polarity of the first episode of BD I. Solar insolation is the amount of electromagnetic energy from the Sun striking a surface area of the Earth. Methods: Data from 7488 patients with BD I were collected at 75 sites in 42 countries. The first episode occurred at 591 onset locations in 67 countries at a wide range of latitudes in both hemispheres. Solar insolation values were obtained for every onset location, and the ratio of the minimum mean monthly insolation to the maximum mean monthly insolation was calculated. This ratio is largest near the equator (with little change in solar insolation over the year), and smallest near the poles (where winter insolation is very small compared to summer insolation). This ratio also applies to tropical locations which may have a cloudy wet and clear dry season, rather than winter and summer. Results: The larger the change in solar insolation throughout the year (smaller the ratio between the minimum monthly and maximum monthly values), the greater the likelihood the first episode polarity was depression. Other associated variables were being female and increasing percentage of gross domestic product spent on country health expenditures. (All coefficients: P ≤ 0.001). Conclusion: Increased awareness and research into circadian dysfunction throughout the course of BD is warranted.

- The paper presents the concept, methodology and preliminary results of the project Regional Absolute Chronologies of the Late Neolithic in Serbia that started in 2020 using a case study from the site of At near Vršac in northeast Serbia. The aim of the project is to create multiple new regional chronological strands consisting of Bayesian modelled radiocarbon dates from sites with material culture belonging to the tradition of the Late Neolithic period Vinča culture. Combining statistical seriation of pottery assemblages and the Bayesian statistical modelling framework of several case studies from various regions of Serbia, new regional chronological anchor points will be created, thus avoiding constant comparison with the assemblage and dating of the eponymous site of Belo Brdo in Vinča. This approach will overcome the effects of the regionalization of material culture evident in most ceramic assemblages located further than 100 kilometers away from the type site. Using archival archaeological records from previous excavations will enable an establishment of a geography of chronological reference points which would then provide new insights into the dynamics of the evolution of the Late Neolithic Vinča societies and changes that occurred throughout its territory during the late sixth and the larger part of the fifth millennia BCE.

- This paper aims to assess the etiology and differential diagnosis of severe pathological lesions in wild and domestic cattle from the Late Neolithic site of At-Vrsac in the northeast part of the present-day Serbia. Excavations of this multilayered site revealed the remains of a Late Neolithic settlement belonging to the Vinca culture network of the Central Balkans. An aurochs metacarpal bone, two domestic cattle fragments of fused ulna and radius and of tibia, all with massive bone proliferations were recovered during the archaeological excavations in 1976. Paleopathological study was undertaken using an interdisciplinary approach, including AMS dating, radiography, computed tomography (CT), and histopathology. The results show severe oblique healed fracture with secondary pronounced bone reaction in the aurochs metacarpal bone and in the domestic cattle ulna-radius, while traumatic alteration infected with disseminated osteomyelitis was found in the domestic cattle tibia. These pathologies of wild and domestic cattle are discussed to reveal the level of environmental and human influence on the origin and development of the lesions in the Late Neolithic cattle.
