AI Article Synopsis
- The study focused on how unit activity in the cat brain cortex recovers after a short recovery from a 5-minute period of anoxia (lack of oxygen).
- It found that short-term anoxia can have a protective effect, but this is only observed when it causes a state known as asphyxic hyperactivity.
- The protective effect is linked to changes in the activity of regulatory systems involving calcium, polyphosphoinositides, and cyclic AMP (cAMP).
Article Abstract
Recovery of unit activity was studied after a 5-min anoxia following a short-term anoxia in the cat brain cortex. The short-term anoxia's protective effect was only revealed in case when it had induced the phenomenon of asphyxic hyperactivity. The protective effect seems to be due to the short-term anoxia-induced changes in the calcium, polyphosphoinositide and cAMP regulatory systems' activity.

Environmental Quality Standards (EQS) derived under the European Water Framework Directive are legally binding and enshrined in individual European Member State Country national legislation. These EQS are derived following well-established guidance documents. In 2013, EQS for nickel were derived for freshwaters to be protective against long and short-term exposures, at 4 and 34 µg L-1, respectively.

Upon exposure to salt stress, calcium signaling in plants activates various stress-responsive genes and proteins along with enhancement in antioxidant defense to eventually regulate the cellular homeostasis for reducing cytosolic sodium levels. The coordination among the calcium signaling molecules and transporters plays a crucial role in salinity tolerance. In the present study, twenty-one diverse indigenous rice genotypes were evaluated for salt tolerance during the early seedling stage, and out of that nine genotypes were further selected for physio-biochemical study.

Previous studies investigating the influence of hot spring bathing on sleep quality have predominantly focused on the short-term effects through questionnaire surveys without blood collection for biochemical tests. Here, we undertook a comprehensive investigation of the long-term health effects of hot spring bathing among the residents of Hot Spring Village. A total of 140 participants were enrolled, and their demographic characteristics and the patterns of hot spring bathing were obtained via face-to-face interview, and sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI).

During winter months, there is increased pressure on health care systems in temperature climates due to seasonal increases in respiratory illnesses. Providing real-time short-term forecasts of the demand for health care services helps managers plan their services. During the Winter of 2022-23 we piloted a new forecasting pipeline, using existing surveillance indicators which are sensitive to increases in respiratory syncytial virus (RSV).

Background: The importance of parathyroid gland preservation in thyroid surgery has been well recognized; however, the rapid identification of the parathyroid gland, particularly the inferior parathyroid gland (IPG), remains challenging. This study aimed to evaluate the effectiveness of retrograde inferior parathyroid protection technique (RIPPT) based on thymus preservation.
Methods: A total of 236 patients were enrolled in this study between August 2019 and December 2020.
