Patients with chronic kidney disease (CKD) have been reported to benefit from different types of exercises. It has also been shown that the ACE inhibitor lisinopril, and the natural product curcumin are also beneficial in different models of CKD in rats. We assessed the influence of moderate swimming exercise (SE) on rats with adenine-induced CKD, and tested the possible effects of lisinopril and/or curcumin thereon using several physiological, biochemical, histopathological and immunohistochemical parameters...

Testosterone is considered to be released from Leydig cells via passive diffusion because of its hydrophobicity; however, the exact mechanism underlying testosterone secretion and the transporter involved are both unknown. Multidrug and toxic compound extrusion (MATE) transporters are predominantly found in the kidneys and liver and are thought to function in the elimination of metabolic organic cations during the final step of excretion in the kidney. In contrast, mMATE2 has been shown to be predominantly expressed in testicular Leydig cells...

Biomarkers to predict the altering physiological conditions over the period leading toward the ocular disorders are of major importance in therapeutics. Isolation and validation of the biomarkers specific to ocular diseases are a challenging task. Glaucoma is a neurodegenerative disease of the eye where the correlation of biomarkers in circulating fluid may be made specific for the eye. However, conditions such as wet age-related macular degeneration (AMD) and proliferative diabetic retinopathy (DR), circulating biomarkers might be having some degree of overlap with other conditions like cancer where a common factor such as angiogenesis is involved...

Uromodulin is the most abundant urinary protein in physiological conditions. It is exclusively produced by renal epithelial cells lining the thick ascending limb of Henle's loop (TAL) and it plays key roles in kidney function and disease. Mutations in UMOD, the gene encoding uromodulin, cause autosomal dominant tubulointerstitial kidney disease uromodulin-related (ADTKD-UMOD), characterised by hyperuricemia, gout and progressive loss of renal function. While the primary effect of UMOD mutations, retention in the endoplasmic reticulum (ER), is well established, its downstream effects are still largely unknown...

The aryl hydrocarbon receptor (AHR) mediates the toxicity of dioxins, but also plays important physiological roles. Selective AHR modulators, which elicit some effects imparted by this receptor without causing the marked toxicity of dioxins, are presently under intense scrutiny. Two novel such compounds are IMA-08401 (N-acetyl-N-phenyl-4-acetoxy-5-chloro-1,2-dihydro-1-methyl-2-oxo-quinoline-3-carboxamide) and IMA-07101 (N-acetyl-N-(4-trifluoromethylphenyl)-4-acetoxy-1,2-dihydro-5-methoxy-1-methyl-2-oxo-quinoline-3-carboxamide)...

Uncontrolled massive bleeding with subsequent derangement of the coagulation system is a major challenge in the management of both surgical and seriously injured patients. Under physiological conditions activators and inhibitors of coagulation regulate the sensitive balance between clot formation and fibrinolysis. In some cases, excessive and diffuse bleeding is caused by systemic activation of fibrinolysis, i. e. hyperfibrinolysis (HF). Uncontrolled HF is associated with a high mortality. Polytrauma patients and those undergoing surgical procedures involving organs rich in plasminogen proactivators (e...

MG53 (also known as TRIM72) is a cardiac and skeletal muscle-specific TRIM-family protein that exhibits multiple biological functions. First, MG53 participates in plasma membrane repair of the heart, skeletal muscle and other tissues. Second, MG53 is essentially involved in the cardioprotection of cardiac ischemic, pre-conditioning and post-conditioning, by activating the PI3K-Akt-GSK3β and ERK1/2 survival signaling pathways. Moreover, systemic delivery of recombinant MG53 protein ameliorates the impact of a range of injury insults on heart, skeletal muscle, lung, kidney, skin and brain...

With our country going into the aging society, burns in the elderly often occur. Studies have shown that the number of elderly burn patients has reached 13% to 20% of the total number of burn patients. As the sensory and cognitive functions are low, skin is thinning, the functions of heart, lung, and kidney are reduced, the immunity is impaired, and other physiological characteristics exist in the elderly, the wounds of elderly burn patients often heal slowly, and the mortality is high. At present, there is still a lack of enough attention to the elderly burn patients...

REVIEW
Amanda J Miller, Jeff Perl, Karthik K Tennankore
The optimal dose of hemodialysis (HD) has not yet been established. As a means of better approximating the physiology of native kidney function, there has been a growing interest in intensive HD (an increase in dialysis frequency and/or duration). Although many studies have demonstrated a survival benefit with intensive dialysis, results have been conflicting. This controversy stems from the challenges of randomizing patients to conventional vs. intensive HD modalities and, therefore, the reliance on observational comparisons that have been limited by varying definitions for intensive dialysis, differences in dialysis location and prescription, unavoidable treatment selection bias, and a potential lack of generalizability...

Obesity and its associated complications, such as insulin resistance and non-alcoholic fatty liver disease, are reaching epidemic proportions. In mice, the TGF-beta superfamily is implicated in the regulation of white and brown adipose tissue differentiation. The Kielin/chordin-like Protein (KCP) is a secreted regulator of the TGF-beta superfamily pathways that can inhibit both TGF-beta and activin signals while enhancing bone morphogenetic protein (BMP) signaling. However, KCP's effects on metabolism and obesity have not been studied in animal models...

The impact of thermal imprinting during development on the plasticity of the hypothalamic-pituitary-interrenal (HPI) axis and stress response in an adult ectotherm, the gilthead sea bream (Sparus aurata, L.), was assessed. Fish were reared under 4 thermal regimes and the resulting adults exposed to acute confinement stress and plasma cortisol levels and genes of the HPI axis monitored. Changes in immune function, a common result of stress, was also evaluated using histomorphometric measurements of melano-macrophages centres (MMCs) in the head kidney and by monitoring macrophage related transcripts...

Mutations in the with-no-lysine kinase 1 (WNK1), WNK4, Kelch-like 3 (KLHL3), and Cullin3 (CUL3) genes were identified as being responsible for hereditary hypertensive disease pseudohypoaldosteronism type II (PHAII). Normally, the KLHL3/CUL3 ubiquitin ligase complex degrades WNKs. In PHAII, the loss of interaction between KLHL3 and WNK4 increases levels of WNKs because of impaired ubiquitination, leading to abnormal over-activation of the WNK-OSR1/SPAK-NCC cascade in the kidney's distal convoluted tubules (DCT)...

Angiotensin converting enzyme(ACE) 2 is a homologue of ACE that catalyzes the conversion of Angiotensin(Ang) II into Ang1-7, which induces vasodilation, anti-fibrotic, anti-proliferative and anti-inflammatory effects. Given that ACE2 counterbalances the effects of Ang II, it has been proposed as a biomarker in kidney disease patients. Circulating ACE2 has been studied in human and experimental studies under physiological and pathological conditions and different techniques have been assessed to determine its enzymatic activity...

Emerging evidence indicates that the fatty acid composition of obesogenic diets influences physiologic outcomes. There are scant data regarding how the content of non-essential fatty acids like monounsaturated fatty acids (MUFA) and saturated fatty acids (SFAs) impact the metabolism of polyunsaturated fatty acids (PUFAs). In this work, we tested the hypothesis that obesogenic diets enriched in oleic acid (OA; 18:1n-9) reduce polyunsaturated fatty acid (PUFA) levels vs an obesogenic diet enriched in SFAs. Adult male mice were fed for eight weeks either (1) a control 16% fat energy (en) diet with 5...

Animal models have been an invaluable means to advance biomedical research as they provide experimental avenues for cellular and molecular investigations of disease pathology. The zebrafish (Danio rerio) is a good alternative to mammalian models that can be used to apply powerful genetic experimental methods normally used in invertebrates to answer questions about vertebrate development and disease. In the case of the kidney, the zebrafish has proven itself to be an applicable and versatile experimental system, mainly due to the simplicity of its pronephros, which contains two nephrons that possess conserved structural and physiological aspects with mammalian nephrons...

The Malpighian tubules of insects are structurally simple but functionally important organs, and their integrity is important for the normal excretory process. They are functional analogs of human kidneys which are important physiological organs as they maintain water and electrolyte balance in the blood and simultaneously help the body to get rid of waste and toxic products after various metabolic activities. In addition, it receives early indications of insults to the body such as immune challenge and other toxic components and is essential for sustaining life...

Transferrin (TF) is recognized as a multifunctional protein and has been implicated in antioxidative, antimicrobial protection, growth, differentiation and cytoprotection effects. An efficient, original three-step isolation procedure for TF consisting in hydrophobic interaction chromatography, gel filtration and preparative electrophoresis was developed. Rainbow trout TF was found to be N-glycosylated (not O-glycosylated) and phosphorylated at all serine, threonine, and tyrosine residues. The protein consists of several proteoforms with an average molecular weight of 76...

BACKGROUND: Prior studies in critically ill patients suggest the supra-physiologic chloride concentration of 0.9% ("normal") saline may be associated with higher risk of renal failure and death compared to physiologically balanced crystalloids. However, the comparative effects of 0.9% saline and balanced fluids are largely unexamined among patients outside the intensive care unit, who represent the vast majority of patients treated with intravenous fluids. METHODS/DESIGN: This study, entitled Saline Against Lactated Ringer's or Plasma-Lyte in the Emergency Department (SALT-ED), is a pragmatic, cluster, multiple-crossover trial at a single institution evaluating clinical outcomes of adults treated with 0...
