Craniofacial changes of ancient populations lived in different eras in Anatolia
Abstract The aim of our study is to determine the changes in craniofacial dimensions among populations lived in Anatolia from different time periods. Eight skulls from the second century AD, 20 skulls were from the tenth–eleventh centuries AD, 20 skulls from the sixteenth–nineteenth centuries AD, and 60 contemporary skulls were included in this cross-sectional observational study. Using computerized tomography scans, five craniofacial dimensions were enrolled: glabella-occipital length (GOL), maximum width (MW), basion-bregma height (BBH), bizygomatic width (BZW), nasion-prosthion height (NPH). The differences of craniofacial dimensions between eras, the effect of sex and/or era on craniofacial dimensions were investigated. The GOL dimensions of the second century AD group were found to be significantly higher than contemporary skulls, and the tenth–eleventh century AD group were also found to be significantly higher than sixteenth–nineteenth century AD group and contemporary skulls (p < 0.001). NPH dimensions of tenth–eleventh century AD group were found to be significantly lower than contemporary group (p = 0.002). The main effect of sex, era, and sex-era interaction on GOL was found statistically significant (p = 0.004, p < 0.001, and p = 0.017, respectively). Only sex had a statistically significant effect on BZW (p < 0.001). Our study showed that GOL has decreased and NPH has increased over the centuries in Anatolian societies. Both sex and era influence the change of GOL.

Understanding the effect of stay-at-home orders on psychological distress during the COVID-19 pandemic: Evidence from a longitudinal study in Australia
The extraordinary public policy response to COVID-19 in Australia saw extended lockdowns in some Australian states and territories, some of the longest in the world. This paper seeks to understand the effect these periods of lockdown had on the mental health of those living through them. Using a staggered difference-in-differences design we study two different periods — one in 2020, one in 2021. During this time there were some jurisdictions (Victoria, New South Wales and in the second period the Australian Capital Territory) experiencing extended lockdowns while the rest of the country was largely living life as normal with no or low local transmission of the virus. While there seems to have been an effect in this first period, we do not find a statistically measurable effect in 2021 as even though distress rose during the lockdown period, it rose similarly among those jurisdictions out of lockdown as well. We speculate this may be because of adaptation to stress, growing cases in control jurisdictions, or the vaccine roll-out providing a concrete endpoint for lockdowns.

Unprecedented Tetravalent Uranium Photocatalysts for Efficient C(sp <sup>3</sup> )─C(sp <sup>3</sup> ) Bond Cleavage and Formation
Abstract Photocatalysis is a pivotal area in synthetic chemistry. Despite extensive application potential in nuclear industry, uranium‐based photocatalysts are historically limited to uranyl(VI/V) redox cycle. Here, we report the discovery of the first tetravalent uranium [U(IV)] photocatalyst that enables efficient C(sp 3 )─C(sp 3 ) bond cleavage and formation under ideal visible light . The U(IV) alkoxy species mediates C─C bond cleavage in a wide range of cycloalkanols and promotes their coupling with electron‐deficient alkenes, providing access to previously unattainable molecular architectures. These U(IV) alkoxy complexes, fully characterized by X‐ray diffraction and magnetic studies, exhibit exceptional photocatalytic efficiency. Quantum chemical studies reveal that the energy barrier for C─C bond cleavage and formation is reduced to below 10 kcal · mol −1 under visible light excitation. This work introduces a new mechanistic paradigm for uranium‐based photocatalysis and positions U(IV) alkoxy complexes as a versatile platform for bond activation and functionalization, expanding the potential applications of depleted uranium in synthetic chemistry.
Effects of alkali stress on antioxidant capacity, lipid metabolism, apoptosis and autophagy of Eriocheir sinensis
Abstract This study investigates the effects of alkali toxicity on Chinese mitten crab (Eriocheir sinensis) exposed to 17.5 mmol/L alkalinity for four weeks. Alkali toxicity resulted in significant physiological responses, notably reducing survival rates. There was a marked increase in MDA content and a decrease in SOD, CAT, and T-AOC levels in the hemolymph. Additionally, there was an elevation of ROS levels in the gills and hepatopancreas, along with Keap1 expression, leading to tissue oxidative damage. Alkalinity exposure induced apoptosis, significantly increasing the mRNA expression of Bax, caspase3, P53, and a notable rise in TUNEL-positive cells. Long-term alkali exposure also reduced hepatopancreas lipid accumulation by promoting CPT1 while inhibiting SREBP, ACC, and CAAT expression. Furthermore, autophagy was considerably influenced by alkali stress, as evidenced by the upregulation of mRNA expression of ATG5, ATG7, LC3a, Beclin1, as well as the protein expression of Beclin1 and parkin. Overall, the findings indicate that alkalinity exposure triggers oxidative stress, lipid metabolic disorder, apoptosis, and autophagy in E. sinensis, providing insights into how E. sinensis adapts to saline-alkali environments and sustainable development in saline-alkali waters.
