A 5-y-old female ferret (Mustela putorius furo) was evaluated for diarrhea, anorexia, and lethargy for 1 wk. Only mild dehydration was detected on physical examination. CBC analysis revealed marked erythrocytosis with an unremarkable plasma biochemistry panel; follow-up CBC analyses revealed a consistent primary erythrocytosis. Whole-body radiographs and abdominal ultrasonography were unremarkable except for a small nephrolith in the right kidney and a small cyst in the left kidney. The plasma erythropoietin level was 17...

Over the past 20 years, there has been an increase in chronic interstitial nephritis in agricultural communities (CINAC) not associated with traditional risk factors. This disease has become an important public health problem and is observed in several countries in Central America and Asia. CINAC predominantly affects young male farmers between the third and fifth decades of life with women, children, and adolescents less often affected. Clinically, CINAC behaves like a chronic tubulointerstitial nephropathy but with systemic manifestations not attributable to kidney disease...

BACKGROUND: Local airway water loss is the main physiological trigger for exercise-induced bronchoconstriction (EIB). AIM: To investigate the effects of whole-body water loss on airway responsiveness and pulmonary function in athletes with mild asthma and/or EIB. METHODS: Ten recreational athletes with a doctor diagnosis of mild asthma and/or EIB completed a randomized, cross-over study. Pulmonary function tests (spirometry, whole-body plethysmography and diffusing capacity for carbon monoxide [DLCO]) were conducted before and after three conditions: i) 2 h exercise in the heat with no fluid intake (dehydration); ii) 2 h exercise with ad libitum fluid intake (control); and iii) time-matched rest period (rest)...

BACKGROUND: Guidelines recommend oral rehydration therapy (ORT) and avoidance of laboratory tests and intravenous fluids for mild to moderate dehydration in children with gastroenteritis; oral ondansetron has been shown to be an effective adjunct. OBJECTIVES: The aim of this study was to determine if a triage-based, nurse-initiated protocol for early provision of ondansetron and ORT could safely improve the care of pediatric emergency department (ED) patients with symptoms of gastroenteritis...

The synthesis of the γ-secretase modulator MK-8428 (1) is described. The synthesis is highlighted by an enzyme-catalyzed reaction to access 3,4,5-trifluoro-(S)-phenylglycine, a 1-pot activation/displacement/deprotection sequence to introduce the aminooxy functionality and a dehydrative intramolecular cyclization under mild conditions to form the oxadiazine heterocycle of 1. In situ reaction monitoring was employed to understand the deleterious role of water during the formation of a methanesulfonate ester in the 1-pot activation/displacement/deprotection sequence...

Daniel M Dawson, Richard I Walton, Stephen Wimperis, Sharon E Ashbrook
The aluminophosphate (AlPO) JDF-2 is prepared hydrothermally with methylammonium hydroxide (MAH(+)·HO(-), MAH(+) = CH3NH3(+)), giving rise to a microporous AEN-type framework with occluded MAH(+) cations and extra-framework (Al-bound) HO(-) anions. Despite the presence of these species within its pores, JDF-2 can hydrate upon exposure to atmospheric moisture to give AlPO-53(A), an isostructural material whose crystal structure contains one molecule of H2O per formula unit. This hydration can be reversed by mild heating (such as the frictional heating from magic angle spinning)...

CASE DESCRIPTION A 3-year-old sexually intact male rabbit (Oryctolagus cuniculus) was evaluated because of a 1-day history of signs of anorexia and depression. CLINICAL FINDINGS Clinical examination revealed signs of depression, hunched posture, low skin elasticity (suggesting dehydration), slightly distended abdomen, and penile and preputial edema. The owner reported that the rabbit had been fed a routine diet, received water via a sipper bottle, and was allowed free movement around the home. It had been observed by the owner to bite and chew gypsum-based plaster from the walls of the home...

Hyperglycaemic emergencies are associated with significant morbi-mortality and healthcare costs. Management consists on fluid replacement, insulin therapy, and electrolyte correction. However, some areas of patient management remain debatable. In patients without respiratory failure or haemodynamic instability, arterial and venous pH and bicarbonate measurements are comparable. Fluid choice varies upon replenishment phase and patient's condition. If patient is severely hypovolaemic, normal saline solution should be the first option...

This study aimed to evaluate and compare the hydration states prior to different sporting events (training sessions, friendly and official matches) in elite female soccer players and relate that to the importance that the player attached to the hydration state as a determinant of sports performance. The hydration state of 17 female elite soccer players (age: 21.5 ± 3 years; body mass: 62 ± 6 kg; body height: 165 ± 9 cm) was determined by measuring their urine specific gravity (USG) prior to three different sports events: training sessions (PT), friendly (PF) and official (PO) matches...

BACKGROUND: Reactivated cytomegalovirus (CMV) infection has been known to cause significant morbidity and mortality in immunocompromised patients. However, CMV disease rarely develops in immunocompetent patients, and reported cases often present with a mild, self-limiting course, without severe life-threatening sequelae. While the colon is the most common gastrointestinal site affected by CMV disease in immunocompetent patients, rectal involvement is rarely reported. CMV proctitis can present in two distinct forms, primary and reactivated...

A novel one-pot benzannulation reaction has been developed for the synthesis of substituted polycyclic aromatic hydrocarbons (PAHs) from the direct coupling of propargylic aldehydes/alcohols with 1,1-diarylethanol through an atom-economical uninterrupted three/four-step reaction sequence under mild and metal-free reaction conditions. The strategy involves an acid-catalyzed dehydration and carbon-carbon bond formation followed by DBU-promoted cycloisomerization. Naphthalene and phenanthrene were obtained via mono-benzannulation, and chrysene, picene and benzopicene were obtained involving consecutive di-benzannulation reactions in good yields starting from easily accessible starting materials...

A subadult male bald eagle ( Haliaeetus leucocephalus ) was presented for severe depression and weakness. Physical examination findings included depressed mentation, dehydration, sternal recumbency, poor body condition, and bilateral, whole-head, horizontal nystagmus. A heavy-metal panel was performed, and blood lead levels were 6.1 ppm. Treatment for lead poisoning was initiated, including subcutaneous fluids and parenteral calcium-disodium ethylenediaminetetraacetic acid, ceftiofur, and meloxicam. Ophthalmic examination findings included absent menace response, absent dazzle reflex, slow and incomplete direct pupillary light reflex, mild anterior uveitis, incipient cataracts, multifocal retinal tears, and retinal separation in both eyes...

We report the case of a 16-year-old female patient with a known history of coeliac disease, who presented with the complaints of diarrhea, vomiting and generalized body weakness. On examination, she was found to have dehydration, decreased power in all her limbs, cervical lymphadenopathy and hepatosplenomegaly. Investigations showed severe hypokalemia, hyponatremia, hypomagnesemia, hypoglycemia and mildly enlarged kidneys on ultrasonography. Biopsy of the duodenum confirmed the flare up of coeliac disease, while cervical lymph node biopsy was positive for atypical lymphoid infiltrate and a morphology suggestive of non-Hodgkin's lymphoma...

Dehydration-responsive element binding (DREB) transcription factor plays an important role in controlling the expression of abiotic stress responsive genes. An intronless oil palm EgDREB1 was isolated and confirmed to be a nuclear localized protein. Electrophoretic mobility shift and yeast one-hybrid assays validated its ability to interact with DRE/CRT motif. Its close evolutionary relation to the dicot NtDREB2 suggests a universal regulatory role. In order to determine its involvement in abiotic stress response, functional characterization was performed in oil palm seedlings subjected to different levels of drought severity and in EgDREB1 transgenic tomato seedlings treated by abiotic stresses...

Chronic constipation is one of the most common chronic gastrointestinal complaints and a frequent reason for consultation. Lifestyle modification and dietary advice attract a lot of patients, often dissatisfied with a long-term drug intake. These behavioral modifications are recommended as a first-line approach in the treatment of chronic mild constipation in the majority of current guidelines despite a low level of evidence. Fiber supplementation is probably the most relevant measure because of a satisfactory level of proof...

Leaf hydraulic supply is crucial to maintaining open stomata for CO2 capture and plant growth. During drought-induced dehydration, the leaf hydraulic conductance (Kleaf) declines, which contributes to stomatal closure and, eventually, to leaf death. Previous studies have tended to attribute the decline of Kleaf to embolism in the leaf vein xylem. We visualized at high resolution and quantified experimentally the hydraulic vulnerability of xylem and outside-xylem pathways and modeled their respective influences on plant water transport...

The Burgess reagent ([methoxycarbonylsulfamoyl]triethylammonium hydroxide) has historically found utility as a dehydrating agent. Herein we show that, in the presence of dimethyl sulfoxide, the Burgess reagent efficiently and rapidly facilitates the oxidation of a broad range of primary and secondary alcohols to their corresponding aldehydes and ketones in excellent yields and under mild conditions, and can be combined with other transformations (e.g., Wittig olefinations). A mechanism similar to those described for the Pfitzner-Moffatt and Swern oxidations is proposed...

Enterotoxigenic Escherichia coli (ETEC) causes severe acute watery diarrhea. No ETEC vaccine is available but candidates are in development, including ETVAX, an oral, whole-cell inactivated vaccine. ETVAX is being tested in a descending-age trial in Bangladesh. If found safe and immunogenic, investigators may test it for efficacy in children. Like oral rotavirus vaccines, we expect that ETVAX will be most effective at decreasing the incidence of moderate-to-severe ETEC episodes. Thus, for an efficacy trial outcome, it will be necessary to triage patients into moderate-to-severe versus mild disease...

Young puppies and kittens have unique physiologic needs in regards to fluid therapy, which must address hydration, vascular fluid volume, electrolyte disturbances, or hypoglycemia. Pediatric patients have a higher fluid requirement compared with adults and can rapidly progress from mild dehydration to hypovolemia. Simultaneously, their small size makes overhydration a real possibility. Patient size complicates fluid administration because catheters used in larger pets may be difficult to place. Routes of fluid administration used in the neonate or pediatric patient include oral, subcutaneous, intraperitoneal, intraosseous, and intravenous...
