Protein kinase CK2 (CK2) is a highly promising target for cancer therapy and anti-CK2 gene expression therapy has shown effectiveness in rodent models of human head and neck cancer (HNC). To date, there has been no large animal model of cancer in which to further explore anti-CK2 therapies. Feline oral squamous cell carcinoma (FOSCC) has been proposed as a large animal model for human HNC and we have previously shown that CK2 is a rational target in FOSCC. We hypothesized that a novel tenfibgen coated tumor-specific nanocapsule carrying RNAi oligonucleotides targeting feline CK2α and CK2α' (TBG-RNAi-fCK2αα') would be safe in cats with FOSCC...

Background Transient non-immune hyperthyroidism in early pregnancy is hyperthyroidism diagnosed for the first time in early pregnancy, without evidence of thyroid autoimmunity or clinical findings of Grave's disease and resolved spontaneously as the pregnancy progressed. Hyperemesis gravidarum (HG) is the commonest cause with 66%-73% of women with severe HG were found to have elevated thyroid function. Materials and methods We conducted a cross sectional study to determine the prevalence of transient hyperthyroidism in patients with hyperemesis gravidarum and its relation to the severity of nausea and vomiting...

Tumors that arise from the endocrine pancreas, or the islets of pancreas, are called pancreatic neuroendocrine tumors (NETs). Pancreatic NET have an incidence of <0.1 per one million persons, and can lead to secretion of ectopic adrenocorticotropic hormone (ACTH). Herein, we presented a case of patient with Cushing's syndrome as a result of ACTH-producing pancreatic NET, who underwent successful laparoscopic distal pancreatosplenectomy. A 40-year-old Korean female patient with ophthalmologic discomfort, osteoporosis, and unexplained hypokalemia was admitted to our hospital...

We report the case of a 41-year-old male patient with juvenile onset refractory hypertension while taking four drugs including a diuretic. Fourteen years before he underwent a complete investigation for secondary hypertension (including the aldosterone to renin ratio-ARR) that was negative. Since that, hypertension control gradually worsened, hypertensive organ damage aggravated and hypokalemia developed in spite of ACE inhibitor treatment. At the re-evaluation ARR was elevated, and the further workup for primary aldosteronism demonstrated an unilateral aldosterone producing adenoma that was surgically removed, with subsequent optimal blood pressure control with two anti-hypertensive drugs...

Thyrotoxic periodic paralysis (TPP) is a rare complication of hyperthyroidism characterized by episodes of muscle weakness and hypokalemia. TPP is typically present in young Asian men, female, and non-Asian ethnic group can also be affected. TPP is a curable cause of hypokalemic periodic paralysis, can often be the first manifestation of thyrotoxicosis. Factors such as high carbohydrate diet, strenuous exercise, emotional stress, and steroid can precipitate an attack of TPP. The presence of both hypokalemia and elevated level of thyroxine (T4) and triiodothyronine (T3) are important diagnostic features during the acute episode...

In animal models of autism spectrum disorder (ASD), the NKCC1 chloride-importer inhibitor bumetanide restores physiological (Cl(-))i levels, enhances GABAergic inhibition and attenuates electrical and behavioral symptoms of ASD. In an earlier phase 2 trial; bumetanide reduced the severity of ASD in children and adolescents (3-11 years old). Here we report the results of a multicenter phase 2B study primarily to assess dose/response and safety effects of bumetanide. Efficacy outcome measures included the Childhood Autism Rating Scale (CARS), the Social Responsive Scale (SRS) and the Clinical Global Impressions (CGI) Improvement scale (CGI-I)...

Adaptation of the organism to potassium (K(+)) deficiency requires precise coordination among organs involved in K(+) homeostasis, including muscle, liver, and kidney. How the latter performs functional and molecular changes to ensure K(+) retention is not well understood. Here, we investigated the role of ubiquitin-protein ligase NEDD4-2, which negatively regulates the epithelial sodium channel (ENaC), Na(+)/Cl(-) cotransporter (NCC), and with no-lysine-kinase 1 (WNK1). After dietary K(+) restriction for 2 weeks, compared with control littermates, inducible renal tubular NEDD4-2 knockout (Nedd4L(Pax8/LC1) ) mice exhibited severe hypokalemia and urinary K(+) wasting...

Aldosterone plays an important role in regulating Na-Cl reabsorption and blood pressure. Epithelial Na(+) channel, Na(+)-Cl(-) cotransporter, and Cl(-)/HCO3(-) exchanger pendrin are the major mediators of Na-Cl transport in the aldosterone-sensitive distal nephron. Existing evidence also suggests that plasma K(+) concentration affects renal Na-Cl handling. In this study, we posited that hypokalemia modulates the effects of aldosterone on pendrin in hyperaldosteronism. Chronic aldosterone infusion in mice increased pendrin levels at the plasma membrane, and correcting hypokalemia in this model almost completely blocked pendrin upregulation...

INTRODUCTION: Type III Bartter syndrome (BS) is an autosomal recessive renal tubule disorder caused by loss-of-function mutations in the CLCNKB gene, which encodes the chloride channel protein ClC-Kb. In this study, we carried out a complete clinical and genetic characterization in a cohort of 30 patients, one of the largest series described. By comparing with other published populations, and considering that 80% of our patients presented the p.Ala204Thr Spanish founder mutation presumably associated with a common phenotype, we aimed to test the hypothesis that allelic differences could explain the wide phenotypic variability observed in patients with type III BS...

The diuretics are essential medicaments of antihypertensive therapy. They reduce blood pressure and cardiovascular events optimally. With increasing doses of thiazides and thiazide analogs do not come further powerful effect of reducing blood pressure or cardiovascular mortality and morbidity, but clearly elevate the side effects. Because of it, the minimum effective dose level and the fixed-dose combination therapy should be preferred. The use these drugs leads to especially positive outcome in elder patients, isolated systolic hypertension, heart failure, after stroke and in black population...

Hypertension is one of the most common problems encountered in the primary care setting. Numerous secondary causes of hypertension exist and are potentially reversible. The ability to screen for such causes and manage them effectively may spare patients from prolonged medical therapy and hypertensive complications. Licorice can cause hypertension and hypokalemia due its effects on cortisol metabolism. We report a case of jelly bean ingestion that highlights the presentation, pathophysiology and management of licorice-induced hypertension...
