This study aimed to characterize body temperature in finishing broiler chickens and to explore heat transfer dynamics under thermoneutral (TN) and heat stress (HS) conditions. To achieve this, 900 Ross 308 chicks were divided into TN and HS groups, with the HS group subjected to cyclical heat stress (30°C, 45 % RH) from day 28 to day 33 post-hatch. Rectal temperature (T) and skin temperature (T) at the face (T), eye (T), and breast (T) were measured.

Breast cancer is one of the leading causes of death for women worldwide, and early detection can help reduce the death rate. Infrared thermography has gained popularity as a non-invasive and rapid method for detecting this pathology and can be further enhanced by applying neural networks to extract spatial and even temporal data derived from breast thermographic images if they are acquired sequentially. In this study, we evaluated hybrid convolutional-recurrent neural network (CNN-RNN) models based on five state-of-the-art pre-trained CNN architectures coupled with three RNNs to discern tumor abnormalities in dynamic breast thermographic images.

Introduction: Pregnancy comprises a period of 41 weeks, in which the female body undergoes several physiological, hormonal and anatomical changes that can generate changes in skin temperature.
Objective: To describe the thermal profile of pregnant women during the first, second and third trimester of pregnancy.
Method: This is a cross-sectional observational study.

Breast thermography may be used for the early detection of breast diseases in women younger than 50 years. Performed breast thermography on a woman in her 20s, revealing an average temperature difference of about 1°C. Ultrasound imaging further identified a simple cyst and enlarged, vascularized lymph nodes in both axillae.
