Gram-negative urease-producing bacilli, Providencia stuartii (P. stuartii), is reported in urinary tract infections, gastroenteritis, and bacteremia in humans but they rarely present with a hepatic abscess. We present a rare case of a recurrent suprahepatic cyst due to P. stuartii in a 45-year-old female, intravenous ( IV) heroin abuser with chronic hepatitis B and C. A 45-year-old female with 10 days status post right suprahepatic abscess drainage presented with recurrent, right, upper quadrant abdominal pain for one day...

The aim of this retrospective study was to identify the major risk factors associated with case fatality in diarrhoeic calves undergoing a standard therapeutic protocol. Clinical and laboratory findings were reviewed in 225 Holstein Friesian diarrhoeic calves over a 2 year period. Calves were treated according to a fluid therapy protocol using an oral electrolyte solution or an IV infusion. After therapy, 159 calves were discharged in a healthy state, whereas 66 calves died. Logistic regression analysis showed that serum total protein (STP) concentration (odds ratio, OR, 0...

S-allyl cysteine (SAC) has antioxidant, antidiabetic and antiobesity properties. We hypothesized that neonatal oral administration of SAC would protect rats against neonatal and adulthood high-fructose diet-induced adverse metabolic outcomes in adulthood. In total, 112 (males=56; females=56), 4-day-old Wistar rat pups were randomly allocated to groups and administered the following treatment regimens daily for 15 days from postnatal day (PND) 6-20: group I - 10 ml/kg distilled water, group II - 10 ml/kg 20% fructose solution (FS), group III - 150 mg/kg SAC and group IV - SAC+FS...

Parenteral administration of Busulfan (BU) conquers the bioavailability and biovariability related issues of oral BU by maintaining the plasma drug concentration in therapeutic range with minimal fluctuations thereby significantly reducing the side effects. Busulfex(®) is the only commercially available parenteral formulation of BU composed of organic solvents N, N-dimethylacetamide and polyethylene glycol 400. Since, BU is highly susceptible to hydrolytic degradation; Busulfex(®) has poor physical and chemical stability in IV fluids...

INTRODUCTION: Type 2 Alcoholism is characterized by low serotonin system functioning and has a high degree of heritability, with offspring of alcoholics often showing a reduced response to the intoxicating effects of ethanol, which is thought to be marker for future alcohol use disorders (AUDs). As such, an important aim of studies investigating the origins of AUDs is understanding the relationship between serotonin system functioning and level of intoxication. A nonhuman primate model was used to evaluate observational ratings of sensitivity to ethanol and to further investigate the relationship between central serotonin activity and behavioral response to ethanol...

A closed-form integro-differential equation (IDE) model of plasma dilution (PD) has been derived which represents both the intravenous (IV) infusion of crystalloid and the postinfusion period. Specifically, PD is mathematically represented using a combination of constant ratio, differential, and integral components. Furthermore, this model has successfully been applied to preexisting data, from a prior human study, in which crystalloid was infused for a period of 30 minutes at the beginning of thyroid surgery...

INTRODUCTION: Prescribing intravenous (IV) fluid therapy is a core skill expected of qualified doctors at the point of graduation, but medical graduates often feel ill-equipped to perform this task. This lack of preparedness contributes to treatment-related patient harm. This scoping review maps the current state of published evidence about how junior doctors prescribe IV fluid therapy and learn how to do it. METHODS: We searched five electronic databases and grey literature from 1994 until June 2016 for articles describing any aspect of IV fluid prescribing practice or its education...

Annexin A1 (AnxA1) is a glucocorticoid-regulated anti-inflammatory protein secreted by phagocytes and other specialised cells. In the endocrine system, AnxA1 controls secretion of steroid hormones and it is abundantly expressed in the testis, ovaries, placenta and seminal fluid, yet its potential modulation of fertility has not been described. Here we observed that AnxA1 knockout (KO) mice delivered a higher number of pups, with a higher percentage of female offsprings. This profile was not dependent on the male features, as sperm from KO male mice did not present functional alterations, and had an equal proportion of Y and X chromosomes, comparable to wild type (WT) male mice...

BACKGROUND: Periodic lack of availability and high cost of commercially produced isotonic fluids for intravenous (IV) use in horses have increasingly led to use of home-made or commercially compound fluids by veterinarians. Data regarding the quality control and safety of compounded fluids would be of benefit to equine veterinarians. OBJECTIVES: To compare electrolyte concentrations, sterility, and endotoxin contamination of commercially available fluids to 2 forms of compounded isotonic crystalloid fluids intended for IV use in horses...

BACKGROUND: Raclopride is a selective antagonist of the dopamine D2 receptor. It is one of the most frequently used in vivo D2 tracers (at low doses) for assessing drug-induced receptor occupancy (RO) in animals and humans. It is also commonly used as a pharmacological blocker (at high doses) to occupy the available D2 receptors and antagonize the action of dopamine or drugs on D2 in preclinical studies. The aims of this study were to comprehensively evaluate its pharmacokinetic (PK) profiles in different brain compartments and to establish a PK-RO model that could predict the brain distribution and RO of raclopride in the freely moving rat using a LC-MS based approach...

OBJECTIVE: Primary psychiatric disorders (PsD) can present with symptomatology identical to that of behavioral variant frontotemporal dementia (bvFTD). To date, clinical guidelines do not provide a solution for this diagnostic challenge. The aim of our study was to prospectively determine which demographic, clinical, neuropsychological, neuroimaging, and cerebrospinal fluid biomarkers are important in distinguishing PsD from bvFTD. METHODS: Patients with late-onset behavioral disturbances (aged 45-75 years, 73% male) were included based on their scores on the Frontal Behavioral Inventory and the Stereotypy Rating Inventory and followed for 2 years from April 2011 to June 2015...

KLK9, 10, 11, and 15 may represent potential cancer biomarkers for evaluating ovarian cancer prognosis. In the present study, we selected a homogeneous cohort including 139 patients of advanced high-grade serous ovarian cancer (FIGO stage III/IV) and assessed the mRNA levels of KLK9, 10, 11, and 15 in tumor tissue by quantitative PCR. No significant associations of KLK9, 10, 11, and 15 mRNA with established clinical parameters (residual tumor mass, ascitic fluid volume) were found. Pronounced correlations between KLK10/KLK11 (rs = 0...

In their late (3(th) and 4th) larval stages, caterpillars of the myrmecophilous lycaenid (Lepidoptera) species Polyommatus coridon and P.icarus respectively, possess on their 8th abdominal segment two eversible so called tentacle organs (TOs). Previous histological and behavioural results have proposed that the TOs may release a volatile substance that elicits "excited runs" in attendant ants. In our study we investigated for the first time the temporal in- and eversion pattern of TOs. Using nerve tracing, Micro-CT, light- and electron microscopy techniques we studied (i) the histology of the 8th abdominal segment, (ii) the fine structure of the cuticular and cellular apparatus of the TOs, (iii) the attachment sites of the retractor muscle of each TO and (iv) the fine structure of the long slender tentacle hairs which are exposed to the outside, when the TOs are everted and fold back into the TO-sac during inversion...

BACKGROUND: Anastomotic dehisense is a serious complication of anterior resections. We have had success in our centre utilising Endosponge therapy to salvage anastomotic leaks but this requires multiple endoscopic sessions and can take around 6 weeks to heal in some cases. This can delay further management such as chemotherapy. AIM: We describe the novel use of Padlock over the scope clips to manage patients with anastomotic dehisense post anterior resection. METHOD: Padlock over the scope clips were used to manage three patients who presented with anastomotic breakdown post laparoscopic anterior resection between February 2016 and July 2017...
