Article Synopsis
- Heat stress (HS) negatively affects water balance in broiler chickens by disrupting kidney function, specifically the aquaporins (AQPs) that help regulate water permeability.
- The study evaluated the expression of kidney AQPs and blood composition in broilers under different conditions, including thermoneutral settings and cyclic heat stress, with and without glucose supplementation.
- Results showed higher expressions of AQPs in heat-stressed birds, increased water consumption, and elevated blood glucose levels, indicating that AQPs play a crucial role in water management during heat stress in chickens.
Background: Pastoralists' sedentarisation and agriculturalisation might increase their vulnerability to climate change impacts, but few studies have investigated if this is the case in mountain areas. In Uganda, little is known about how Sebei pastoralists have perceived and adapted to such changes. This study sought to establish perspectives of Sebei pastoralists on climate change in terms of its occurrence and impacts as well as access to livelihood assets and or opportunities to withstand such challenges.

Ability of poultry to regulate their core body temperature relative to the ambient temperature depends on the relative nutrient/energy expenditure in maintenance and performance requirements. We hypothesized that changes in rectal temperature corrected for surface area can be used as a measure of heat tolerance/sensitivity.

Additionally, understanding factors associated with the choice of response strategies to certain public health threats provides an opportunity to design context-specific interventions.
Methods: We used polytomous latent class analyses to group participants' responses and an additive Bayesian modelling network to explore satisfaction with health service delivery as well as factors associated with response strategies of households to malaria.
Article Synopsis
- Birds exhibit molecular differences in water intake, categorized as high residual water intake (HRWI) and low residual water intake (LRWI), based on their actual water consumption versus what is expected given their metabolic rates.
- In LRWI birds, there is a notable increase in kidney metabolites like glucose and fructose, while specific sodium-glucose cotransporters (SGLTs) show altered expression levels that suggest a role in water regulation.
- The increased expression of the SGLT4 transporter and GLUT2 in LRWI birds is hypothesized to enhance water efficiency and glucose retention, influencing their overall drinking behavior.
