Diabetic nephropathy (DN) arises from systemic and local changes in glucose metabolism hemodynamics. We have reported that many glycolytic mitochondrial enzymes, such as pyruvate kinase M2 (PKM2), were elevated renal glomeruli of DN-protected patients with type 1 2 diabetes. Here, mice PKM2 overexpression specifically podocytes (PPKM2Tg) generated to uncover the protective function PPKM2Tg a potential therapeutic target prevented albumin/creatinine ratio (ACR), mesangial expansion, basement...

Insulin resistance (IR) can increase atherosclerotic and cardiovascular risk by inducing endothelial dysfunction, decreasing nitric oxide (NO) production, accelerating arterial inflammation. The aim is to determine the mechanism which insulin action NO production in cells improve systemic bioenergetics decrease atherosclerosis via differentiation of perivascular progenitor (PPCs) into brown adipocytes (BAT).Studies used various transgenic deletion mutant ApoE-/- mice receptors, eNOS...

Tuberculous (TB) lymphadenitis can mimic cervical node metastasis from papillary thyroid carcinoma (PTC) since the distribution and appearance of affected lymph nodes are similar. We present case an asymptomatic 50-year-old Filipino who sought consult for a gradually enlarging anterior neck mass single palpable node. Preoperative workup suggested malignancy with nodal metastasis. He underwent total thyroidectomy dissection where histopathology confirmed follicular variant- (FV-) PTC. Lymph...

Abstract Disclosure: M. Yu: None. S. Jangolla: N. Ziemniak: E. Viebranz: T. Chokshi: K. Park: I. Wu: H. Shah: G.L. King: Cardiovascular disease (CVD) is a major cause of mortality in people with Type 1 diabetes (T1D), especially those nephropathy (DN). However, long-duration T1D, substantial proportion individuals without DN still exhibit excessive CVD risks. The Joslin 50-Year “Medalist” Study (n=1043), composed T1D≥50 years, are ideal for studying renoprotected T1D cohort, as only 13% have...
