Summary: This study revealed the diversity of infant feeding strategies practiced across different historical eras and geographical locations. By analyzing stable isotopes and dental samples from ancient human remains, we identified dietary changes during the breastfeeding, weaning, and post-weaning periods, as well as the influence of cultural practices on the duration of weaning.

Summary: This research investigates the effect of weaning after similar to 6 months of age on cholera mortality among 18th-19th-century Italian populations. The results show that age-at-weaning completion was not a predisposing factor in cholera mortality in adulthood, possibly because weaning completion likely occurred after infants had adapted to consuming contaminated weanling foods.

Summary: The lipid profile of jejunal crypt cells in early-weaned piglets undergoes significant changes, particularly between post-weaning day 3 and 14. Potential lipid biomarkers for weaning stress in crypt cells were identified. These findings provide new insights into the intestinal dysfunctions caused by weaning stress.

Summary: This study revealed significant changes in lipid profile of jejunal crypt cells in early-weaned piglets, particularly on post-weaning day 3. The alterations in lipid profile could be related to inflammation caused by early weaning stress.

Summary: Nitrogen stable isotope ratios (delta N-15) of dentine collagen are used to study breastfeeding and weaning practices in ancient populations. However, the estimation of weaning age is currently done visually, which is time-consuming and prone to errors. To solve this issue, we developed WEAN, an automated tool that estimates weaning age based on delta N-15 measurements. The tool uses regression analysis to generate accurate age assignments and calculates the knee/elbow point of the delta N-15 curvature as the weaning age. Testing on published datasets showed good agreement between visual observation and the elbow method, demonstrating the tool's accuracy. WEAN can estimate weaning age for individuals and produces visually appealing graphics and output files. It streamlines the exploration of breastfeeding and weaning patterns in antiquity.

Summary: Weaning of pigs in commercial pork production induces stress and affects behavior, performance, and gastrointestinal tract. Traditional focus has been on nutritional strategies, housing conditions, and medication after weaning, but alternative pre-weaning systems that promote natural social behaviors of piglets have gained attention. Strategies like co-mingling non-littermates and intermittent suckling aim to initiate social interaction and gradual separation from the sow. These practices encourage explorative nutrient sourcing and reduce weaning-associated stress. The review defines these strategies and describes their effects on various aspects.

Summary: The translation above explains the process of dentineogenesis and the role of DSPP in tooth development. DSPP mutations can lead to hereditary dentine diseases, and DSPP plays a crucial role in dentine formation and odontoblast differentiation. Additionally, DSPP interacts with integrins and other molecules to regulate intracellular signaling and promote hydroxyapatite crystal growth and mineralization.

Summary: Matrix metalloproteinases (MMPs) play a critical role in dentine formation and repair, with their function being complex and essential for dentine regeneration beyond just inhibiting activity. MMPs are considered important candidates for dentine regeneration due to their involvement in the dentine matrix as bioactive components.

Summary: Weaning is a critical period in pig production, but it often causes stress for piglets due to separation from the sow, changes in diet and living environment, and social challenges. This stress leads to changes in the piglets' small intestine, disrupting digestion and absorption, damaging intestinal barrier function, and resulting in reduced feed intake, increased diarrhea rate, and growth retardation. Understanding the effects of weaning stress on intestinal health is important for developing nutritional strategies to alleviate weaning stress.

Summary: There are differences in immune development among different pig breeds, as shown by variations in immune indicators in plasma and ileum. Taoyuan black and Xiangcun black piglets demonstrate stronger resistance to weaning stress compared to Duroc piglets.

Summary: The study demonstrated that supplementing AN-GOX in the diet of weaning pigs improved average daily gain and increased antioxidant enzyme concentrations in the blood linearly with the dosage. However, it had no effects on nutrient digestibility, fecal microbiota, and fecal gas emission.

Summary: This study aimed to find a dentine analogue material with mechanical properties and fatigue behaviors that could replace human dentine in a crown fatigue laboratory test. Experimental, analytical, and numerical methods were used to investigate and compare woven glass fibre-filled epoxy and glass fibre-reinforced polyamide-nylon with human dentine. The results showed that the two analogue materials exhibited similar mechanical properties and fatigue behaviors to human dentine, with the glass fibre-filled epoxy performing better in terms of reliability and predictability.

Summary: At the atomic level, heat is considered to be energy for lattice vibrational waves. The strain, as atomic displacement, has a significant impact on thermal transport. Experimental efforts in studying the strain-dependent thermal properties of nanostructures and thin films are limited. This study stretched 2 μm-thick Si films to investigate the influence of uniaxial tensile strain on in-plane thermal conductivity.

Summary: By combining a large dataset of δ13C enamel data with estimates of woody cover in 30 African ecosystems, the study shows little correlation between intrataxonomic variation in δ13C enamel and vegetation structure. Therefore, the authors recommend a community-level approach for making vegetation inferences.

Summary: The discovery of a decorated ivory pendant from the Paleolithic layers at Stajnia Cave in Poland marks the oldest known human-modified punctate ornament, dating back to 41,500 years ago. This unique piece establishes a new starting point for a tradition directly linked to the spread of modern Homo sapiens in Europe.

Summary: Carbon isotopic analysis has challenged our understanding of hominin diet. A study in 1994 revealed that Paranthropus robustus primarily consumed C3 foods but also some C4/CAM resources. However, later studies showed that Paranthropus boisei ate mostly C4/CAM plants and lacked evidence of consuming hard objects. This raises questions about the diet differences between the two robust australopiths and how P. boisei could consume tough foods with its teeth. This review examines new isotopic data and discusses digestives strategies for P. boisei.
