- - The study aimed to investigate how changing light-dark cycles and consuming soft drinks affect the early development of type 1 diabetes mellitus (T1DM) in non-obese diabetic (NOD) mice.
- - Female NOD mice were tested from 5 weeks old, and adjustments were made to their light cycles and diets until they either developed diabetes or reached 30 weeks old.
- - Results showed that NOD mice with altered light cycles developed T1DM approximately two weeks earlier than control mice, but this finding wasn't statistically significant, indicating a need for more research with larger groups.
Article Synopsis
- - Self-medication practices surged during the COVID-19 pandemic as people stockpiled medications, with roughly 80% taking action in response to the uncertainty and lack of effective treatments.
- - A study conducted in southwestern Ethiopia surveyed 415 pharmacy clients to identify factors influencing self-medication, utilizing various statistical analyses to explore these associations.
- - Findings indicated that self-medication was more common among females, those with higher education, individuals frustrated with public health facility wait times, and those fearing COVID-19, with analgesics and cold medicines being the most commonly used.
Article Synopsis
- Chronotype refers to an individual's internal clock that affects various aspects of daily life, and understanding its factors is important for research on health.* -
- A study conducted in Saudi Arabia with 1,369 adults aimed to examine the relationship between chronotype and factors like meal frequency and physical activity, finding significant links with demographic variables such as age and employment.* -
- The results revealed that the population was categorized into morning-type (34.1%), neither-type (41.6%), and evening-type (24.3%), and showed associations between chronotype and eating habits as well as levels of physical activity.*
