Background: Photosynthesis and cellular respiration play major roles in energy metabolism and are important Life Science topics for K16 Biology students. Algae beads are used for photosynthesis and cellular respiration labs. Currently there are a few companies that sell biology educational kits for making algae beads using non-motile green micro-algae to introduce students to photosynthesis.

While studies have documented the efficacy of some NAD+ precursors such as nicotinamide riboside (NR) in raising plasma NAD+, no data are currently available on the fate of directly infused NAD+ in a human cohort. This study, therefore, documented changes in plasma and urine levels of NAD+ and its metabolites during and after a 6 h 3 μmol/min NAD+ intravenous (IV) infusion.

Few studies have assessed changes in breastfeeding rates by race after implementing the Ten Steps to Successful Breastfeeding (hereafter referred to as the Ten Steps), and none have assessed the association between implementation and changes in racial disparities in breastfeeding rates. Our goal was to determine if a hospital- and community-based initiative in the Southern United States could increase compliance with the Ten Steps, lead to Baby-Friendly designation, and decrease racial disparities in breastfeeding.

- The study examines how methamphetamine (METH) affects core body temperature, focusing on how tolerance develops with chronic use and the role of ambient temperature.
- Rats were treated with varying doses of METH in controlled temperature settings, and their core temperatures were monitored for 12 days to assess changes over time and under different conditions.
- Findings indicate that peak temperature responses to METH occur at different times based on dosage, that chronic use leads to reduced temperature responses not linked to long-term neurochemical changes, and that the temperature response is characterized by two distinct phases due to different underlying mechanisms.
Rationale: Subchronic administration of stimulants reduces basal dopamine (DA) concentrations and blocks stress-induced DA release in the nucleus accumbens (NA) of rats during withdrawal. However, no studies have attempted to relate early withdrawal from chronic drug exposure to stress reactivity and changes in DA transmission.
Objectives: The effects of subchronic low-dose methamphetamine (METH) administration on regional changes in dopamine transporter (DAT) and norepinephrine transporter (NET) immunoreactivity and function during early withdrawal were examined.
