Several members of the SLC9A family of Na(+)/H(+) exchangers are expressed in the gut, with varying expression patterns and cellular localization. Not only do they participate in the regulation of basic epithelial cell functions, including control of transepithelial Na(+) absorption, intracellular pH (pH i ), cell volume, and nutrient absorption, but also in cellular proliferation, migration, and apoptosis. Additionally, they modulate the extracellular milieu in order to facilitate other nutrient absorption and to regulate the intestinal microbial microenvironment...

This is a case report of a 30-year-old patient presenting at advanced gestation with hyperemesis, who developed a prolonged QT interval secondary to electrolyte imbalance during recovery. This potentially fatal complication should be considered in all patients with hyperemesis gravidarum, especially after a prolonged period of starvation. We hope to highlight the importance of ECG monitoring and careful prescribing in such cases, something that is not considered in current guidelines.

Ogilvie's syndrome, also known as 'paralytic ileus of the colon', is characterised by pseudo-obstruction of the large intestine in the absence of any mechanical obstructing component; and presents as a massively distended abdomen. If left untreated, it may lead to bowel perforation or ischemia. Ogilvie's syndrome usually presents as a postsurgical complication, mainly due to the lack and/or restriction of movement coupled with a possible electrolyte imbalance. Here, we present a case of a pre-surgical 63-year lady, having a right hip fracture, who came with complaints of severe abdominal pain and distension for 4 days...

Searsia chirindensis (SC) (Baker F.) (Anacardiaceae) has shown potential for the treatment of many neurological diseases however its effect on other bodily systems in neurotoxic models is not well-documented. In this study we investigated the effects of SC on blood glucose homeostasis, as well as its effect on liver and kidney function by assessing lipid peroxidation using the TBARS assay and measuring plasma and urinary electrolyte concentrations in a 6-hydroxydopamine parkinsonian model. The relative levels of phytochemicals were also quantified, along with testing free radical scavenging activity via the DPPH assay...

Primary hypoadrenocorticism, or Addison's disease, is an autoimmune condition common in certain dog breeds that leads to the destruction of the adrenal cortex and a clinical syndrome involving anorexia, gastrointestinal upset, and electrolyte imbalances. Previous studies have demonstrated that this destruction is strongly associated with lymphocytic-plasmacytic inflammation and that the lymphocytes are primarily T cells. In this study, we used both immunohistochemistry and in situ hybridization to characterize the T-cell subtypes involved...

Benign prostatic hyperplasia (BPH) represents one of the most common conditions encountered in urological practice. For many years, transurethral resection of the prostate (TURP) has been considered the gold standard for surgical management of symptoms in prostates of 30 cc-80 cc. Although TURP provides excellent functional outcomes, there is significant morbidity associated with the procedure, particularly with regards to bleeding, electrolyte imbalance and sexual dysfunction. Emerging technologies aim to maintain the excellent functional results of TURP whilst decreasing the adverse events experienced by the patient...

Suganthini Krishnan Natesan, Pranatharthi H Chandrasekar
The majority of invasive mold infections diagnosed in immunocompromised cancer patients include invasive aspergillosis (IA) and mucormycosis. Despite timely and effective therapy, mortality remains considerable. Antifungal agents currently available for the management of these serious infections include triazoles, polyenes, and echinocandins. Until recently, posaconazole has been the only triazole with a broad spectrum of anti-mold activity against both Aspergillus sp. and mucorales. Other clinically available triazoles voriconazole and itraconazole, with poor activity against mucorales, have significant drug interactions in addition to a side effect profile inherent for all triazoles...

SeSAME/EAST syndrome is a multisystemic disorder in humans, characterised by seizures, sensorineural deafness, ataxia, developmental delay and electrolyte imbalance. It is exclusively caused by homozygous or compound heterozygous variations in the KCNJ10 gene. Here we describe a similar syndrome in two families belonging to the Malinois dog breed, based on clinical, neurological, electrodiagnostic and histopathological examination. Genetic analysis detected a novel pathogenic KCNJ10 c.986T>C (p.(Leu329Pro)) variant that is inherited in an autosomal recessive way...

Ionic charge carrier formation and mobility, including the underlying conduction mechanisms, are investigated for phosphoric acid at water contents relevant for the acid's application as electrolyte in fuel cells. The high conductivity contribution from structural diffusion involving intermolecular proton transfer (∼97%) in neat phosphoric acid (H3PO4) passes through a maximum at this composition. Hydrogen bond network frustration (imbalance of the number of proton donors and acceptors), which is closely related to the appearance of structural diffusion, decreases with both elimination and addition of water...

Transport properties and hydration behavior of phosphoric acid/(benz)imidazole mixtures are investigated by diverse NMR techniques, thermogravimetric analysis (TGA) and conductivity measurements. The monomeric systems can serve as models for phosphoric acid/poly-benzimidazole membranes which are known for their exceptional performance in high temperature PEM fuel cells. (1)H- and (31)P-NMR data show benzimidazole acting as a strong Brønsted base with respect to neat phosphoric acid. Since benzimidazole's nitrogens are fully protonated with a low rate for proton exchange with phosphate species, proton diffusion and conduction processes must take place within the hydrogen bond network of phosphoric acid only...

Electrolytic disorders of the inner ear represent a model that could be implicated in partially explaining the pathogenesis of sudden sensorineural hearing loss (SSNHL). Different types of electrolytes and different inner-ear loci are involved in cochlear homeostasis physiologically, to ensure the maintenance of an ion-balanced cochlear environment allowing a normal hair cell function. It has been hypothesized that a sudden loss of endocochlear potential, due to a rapid disruption of the inner ear fluid osmolality, could be responsible for a deterioration of the hearing function caused by damaged hair cells...
