The mammalian kidney collecting ducts are critical for water, electrolyte and acid-base homeostasis and develop as a branched network of tubular structures composed of principal cells intermingled with intercalated cells. The intermingled nature of the different collecting duct cell types has made it challenging to identify unique and critical factors that mark and/or regulate the development of the different collecting duct cell lineages. Here we report that the canonical Notch signaling pathway components, RBPJ and Presinilin1 and 2, are involved in patterning the mouse collecting duct cell fates by maintaining a balance between principal cell and intercalated cell fates...

AIM: Hyperemesis gravidarum (HG) can be defined as intractable nausea and vomiting leading to electrolyte imbalance, ketonuria, nutrition deficiency and weight loss. Inflammation is known to play a crucial role in HG and many inflammatory markers have been studied to achieve early diagnosis. We investigated the association of the platelet to lymphocyte ratio and plateletcrit with the presence and severity of HG. METHODS: We retrospectively enrolled 433 pregnant women with a diagnosis of HG and 160 gestational age matched healthy pregnant women, who were admitted to a large tertiary research and training hospital between January and December 2015...

The 2015 Dietary Guidelines Advisory Committee indicated that magnesium was a shortfall nutrient that was underconsumed relative to the Estimated Average Requirement (EAR) for many Americans. Approximately 50% of Americans consume less than the EAR for magnesium, and some age groups consume substantially less. A growing body of literature from animal, epidemiologic, and clinical studies has demonstrated a varied pathologic role for magnesium deficiency that includes electrolyte, neurologic, musculoskeletal, and inflammatory disorders; osteoporosis; hypertension; cardiovascular diseases; metabolic syndrome; and diabetes...

The kidneys play a vital role in the excretion of waste products and the regulation of electrolytes, maintenance of acid-base balance, regulation of blood pressure, and production of several hormones. Any alteration in the structure of the nephron (basic functional unit of the kidney) can have a major impact on the kidney's ability to work efficiently. Progressive decline in kidney function can lead to serious illness and ultimately death if not treated by dialysis or transplantation. While there have been numerous studies that implicate lower nephron numbers as being an important factor in influencing susceptibility to develop hypertension and chronic kidney disease, a direct association has been difficult to establish because of three main limitations: (1) the large variation in nephron number observed in the human population; (2) no established reliable non-invasive methods to determine nephron complement; and (3) to-date, nephron measurements have been done after death which doesn't adequately account for potential loss of nephrons with age or disease...

In this work, we report the development of well-ordered hydrogenated CoMoO4 (H-CoMoO4) and hydrogenated Fe2O3 (H-Fe2O3) nanoplate arrays on 3D graphene foam (GF), and explore their practice application as binder-free electrodes in assembling flexible all-solid-state asymmetric supercapacitor (ASC) device. Our results show that the monolithic 3D porous GF prepared by solution casting method using Ni foam template possesses large surface area, superior electrical conductivity, and sufficient surface functional groups, which not only facilitate in situ growth of CoMoO4 and Fe2O3 nanoplates on it, but also contribute the double-layer capacitance of resultant supercapacitor...

Acute viral hepatitis is usually a self-limiting illness. However, it can lead to complications that can be life-threatening, such as acute liver failure. Glucose 6 phosphate dehydrogenase (G6PD) deficiency in the setting of acute viral hepatitis can lead to a massive hemolysis, manifesting as acute kidney injury and markedly raised bilirubin levels; although cases are rare. Here, we report such a case. The patient had a viral hepatitis E infection and presented with kidney injury requiring dialysis. Examination showed very high mixed hyperbilirubinemia due to massive intravascular hemolysis...

Proton Pump Inhibitors are among the most common drugs taken. The indication is for treatment of heartburn, reflux disease, prophylaxis and treatment of peptic ulcers, in combination with NSAIDs and steroids as well as H. pylori-eradication. PPI's are widely used, even with non-specific symptoms. This certainly has to do with good tolerability and a previously considered low side effect profile. At the moment, there is growing evidence that the long-term intake of PPI's may not be as safe as assumed. In addition to interactions with some drugs, including platelet aggregation inhibitors, recent studies have shown an increased risk of myocardial infarction, interstitial nephritis, chronic renal injury, infections, vitamin deficiencies and electrolyte shifts as well developing dementia...

BACKGROUND: Earlier studies demonstrated that alcoholism significantly alters electrolyte and trace element homeostasis. However, the existing data on the interplay between maternal alcohol consumption and fetal trace element status are contradictory. Therefore, the primary objective of the present study was to assess the influence of alcohol consumption on maternal and cord blood trace elements. METHODS: A total of 30 pregnant women (15 women consuming alcohol and 15 controls) were examined...

Macro- and microminerals are required for all physiological processes in beef cattle. When mineral deficiencies occur in pasture-based production systems, a multitude of deficiency symptoms may occur, and most often, these deficiencies result in hidden losses to include reduced production potential, reduced immunity, and reproductive failure. More severe deficiencies will result in specific deficiency symptoms, depending on the specific mineral deficiency. In pasture-based beef operations, specific deficiency symptoms are seldom observed...

Low performance of cathode materials has become one of the major obstacles to the application of lithium-ion battery (LIB) in advanced portable electronic devices, hybrid electric vehicles, and electric vehicles. The present work reports a versatile oxygen-deficient LiV3O8 (D-LVO) nanosheet that was synthesized successfully via a facile oxygen-deficient hydrothermal reaction followed by thermal annealing in Ar. When used as a cathode material for LIB, the prepared D-LVO nanosheets display remarkable capacity properties at various current densities (a capacity of 335, 317, 278, 246, 209, 167, and 133 mA h g(-1) at 50, 100, 200, 500, 1000, 2000, and 4000 mA g(-1), respectively) and excellent lithium-ion storage stability, maintaining more than 88% of the initial reversible capacity after 200 cycles at 1000 mA g(-1)...

Calcineurin dephosphorylates NFAT transcription factors, thereby facilitating T-cell mediated immune responses. Calcineurin inhibitors are instrumental for immunosuppression after organ transplantation, but may cause side effects including hypertension and electrolyte disorders. Kidneys were recently shown to display activation of the furosemide-sensitive Na-K-2Cl cotransporter (NKCC2) of the thick ascending limb and the thiazide-sensitive Na-Cl cotransporter (NCC) of the distal convoluted tubule upon calcineurin inhibition using cyclosporin A (CsA)...

Alcohol is one of the most commonly abused substances worldwide. It results in a wide range of diseases and disorders affecting many organ systems. Alcohol-related nutritional deficiencies and electrolyte disturbance leave chronic abusers at risk of a range of demyelinating conditions to which the radiologist and clinician should always be alert. These include Wernicke's encephalopathy, Korsakoff's syndrome, Marchiafava-Bignami disease and osmotic demyelination. Cerebral volume loss is also a commonly encountered neuroimaging phenomenon in chronic alcohol abusers...

Hypokalaemia is a common clinical problem. It can lead to severe disturbances in cardiac, neurological and muscle function. We present the case of a 45-year-old woman who was transported to our hospital with cardiac arrest following ventricular fibrillation. Blood sampling revealed severe acidosis (pH 7.02) and extreme hypokalaemia (0.9 mmol/l). The low serum potassium level was most likely caused by the combination of a very deficient diet and use of a thiazide diuretic. She never reported any symptoms. An acute intracellular shift of potassium due to epinephrine and perhaps also the cathecholamines in Red Bull may have further decreased the serum potassium concentration...

PURPOSE OF REVIEW: Chronic rejection is associated with persistent mononuclear cell recruitment, endothelial activation and proliferation, local tissue hypoxia and related biology that enhance effector immune responses. In contrast, the tumor microenvironment elicits signals/factors that inhibit effector T cell responses and rather promote immunoregulation locally within the tissue itself. The identification of immunoregulatory check points and/or secreted factors that are deficient within allografts is of great importance in the understanding and prevention of chronic rejection...
