Cardiorespiratory Responses to Voluntary Hyperventilation During Normobaric Hypoxia.

Unexplained physiological events (PE), possibly related to hypoxia and hyperventilation, are a concern for some air forces. Physiological monitoring could aid research into PEs, with measurement of arterial oxygen saturation (So₂) often suggested despite potential limitations in its use. Given similar physiological responses to hypoxia and hyperventilation, the present study characterized the cardiovascular and respiratory responses to each.

Chronic Total Occlusion of the Left Main Coronary Artery in an HIV-Infected Patient.

Coronary artery disease (CAD) is amongst the leading causes of death in human immunodeficiency virus (HIV)-infected persons. Severe left main disease (LMD) occurs in approximately five percent of HIV-infected patients, with chronic total occlusion (CTO) of this vessel being an even rarer phenomenon. We describe a non-adherent HIV-infected patient with a left main coronary artery (LMCA) CTO that presented with heart failure with mildly reduced ejection fraction (HFrEF) and ventricular tachycardia (VT).

Sense of coherence and incidence of periodontal disease in adults.

Aim: To assess whether sense of coherence (SOC) predicts the 4-year incidence of periodontal disease in adults.

Methods: Data from 848 adults who participated in both the Health 2000 Survey and the Follow-Up Study of Finnish Adults' Oral Health were analysed. At baseline, participants provided information on demographic characteristics, education level, the SOC scale, pre-existing diabetes and dental behaviours.

Investigation of the wound healing activity of Carapa guianensis L. (Meliaceae) bark extract in rats using excision, incision, and dead space wound models.

The objective of our study is to investigate the wound healing activity of the bark extract of Carapa guianensis in rats using three different wound models. The animals were randomly divided into two groups of six each in all the models. Test group animals were treated topically with the bark extract (200 mg/kg of body weight), and the controls were treated with petroleum jelly in the excision wound model.

Experimental evaluation of ethanolic extract of Carapa guianensis L. Leaf for its wound healing activity using three wound models.

The leaves of Carapa guianensis have been used to treat ulcers, skin parasites, and skin problems. The ethanolic extract of C. guianensis leaf was evaluated for its antibacterial and wound healing activity using excision, incision and dead space wound models in rats.
