Targeting Obesity and Diabetes to Treat Heart Failure with Preserved Ejection Fraction.

Heart failure with preserved ejection fraction (HFpEF) is a major unmet medical need that is characterized by the presence of multiple cardiovascular and non-cardiovascular comorbidities. Foremost among these comorbidities are obesity and diabetes, which are not only risk factors for the development of HFpEF, but worsen symptoms and outcome. Coronary microvascular inflammation with endothelial dysfunction is a common denominator among HFpEF, obesity, and diabetes that likely explains at least in part the etiology of HFpEF and its synergistic relationship with obesity and diabetes.

Trypsin inhibitory capacity in vernal keratoconjunctivitis.

Purpose: To study tear trypsin inhibitory capacity (T-TIC), serum trypsin inhibitory capacity (S-TIC) and their relationship to matrix metalloproteinases (MMP)-1 and -9 in patients with vernal keratoconjunctivitis (VKC).

Methods: In the first phase of the study, inactivation of alpha-1 antitrypsin (AAT) by MMP-1 and -9 was investigated in vitro. Subsequently, tear samples were collected after clinical evaluation from 14 patients with active VKC and 15 normal control subjects.

Alpha-1-antitrypsin phenotypes and HLA-B27 typing in uveitis patients in southeast Iran.

Objectives: Uveitis is an eye disease that affects humans worldwide. Inflammation of the uveal tract is termed uveitis. Alpha-1-antitrypsin (AAT) deficiency is one of many factors that may be involved in abnormalities such as liver and lung disease, inflammatory joint diseases, and inflammatory eye diseases.
