We have used an unbiased statistical approach to compare the pace of development in the main and accessory olfactory systems in monotremes and metatherians with that in rodents and humans. We hypothesized that if metatherians and monotremes, which are born at small body size, use olfaction to locate the pouch and/or teat/milk field, then olfactory structures should reach structural maturity in metatherians and monotremes at a smaller size than eutherians like humans and rodents. The achievement of key structural milestones in the development of the main and accessory olfactory systems (11 and 7 milestones, respectively) was scored for 354 specimens and compared against a measure of general somatic growth (body length)...

PURPOSE: The timing of J-pouch surgery following colectomy for children with very early-onset colitis is controversial, with some advocating early reconstruction and others delaying reconstruction because of fear that the colitis may be owing to Crohn's disease (CD). We sought to determine the long-term incidence of CD in this population and whether there may be clinical features that predict the risk of CD. METHODS: Children with noninfectious colitis diagnosed prior to age 10, who underwent subtotal colectomy and ileostomy from 2000 to 2015, were reviewed...

BACKGROUND: Trauma and major surgery cause extensive immune hyporeactivity in patients. Thus, the preventive, preoperative application of immunoregulatory therapeutics may normalize this immune reactivity and decrease morbidity and mortality in these subjects. OBJECTIVES: The aim of this study was to investigate the immunomodulatory actions of recombinant human lactoferrin (rhLF) in mice, and to relate these effects to in vitro actions of rhLF on tumor necrosis factor alpha (TNF-α) production in lipopolysaccharide-stimulated whole blood cell cultures (LPS-stimulated WBCC) from patients admitted to intensive care units...

The objectives of this work were to determine the effect of 3 levels of residual air and 2 different retort motions on the value of the average heating slope of the rate of heat penetration of 3 different viscosities of a food simulant in flexible retort pouches. Pouches were thermally processed in a water spray automated batch retort system using 2 different methods of motion: static and oscillating continuously at a speed of 10.5 rotations per min (RPM) with an angle of 15°. Nine residual air and viscosity combinations were processed during each experimental run: low viscosity with no residual air (LV-NRA), medium viscosity with no residual air (MV-NRA), high viscosity with no residual air (HV-NRA), low viscosity with medium residual air (LV-MRA), medium viscosity with medium residual air (MV-MRA), high viscosity with medium residual air (HV-MRA), low viscosity with high residual air (LV-HRA), medium viscosity with high residual air (MV-HRA), and high viscosity with high residual air (HV-HRA)...

PURPOSE: Dandy-Walker malformation is a rare condition due to imperforation of the Blake's pouch during intrauterine brain development, usually leading to early severe hydrocephalus. The association with holocord syringomyelia is rare, and from the Gardner's first report in 1957, only 23 cases have been described, mostly from autopsy series and pre-MRI period. Besides a worsening of clinical picture, its occurrence generates some concern about the best surgical treatment that varies widely among the literature reports...

Lucrin Depot (AbbVie), a 1-month microsphere gonadotrophin-releasing hormone (GnRH) agonist preparation, was investigated as a potential agent to synchronise cycling in the fat-tailed dunnart (Sminthopsis crassicaudata). Forty-eight randomly selected females were treated with 5 or 10mgkg-1 Lucrin Depot (n=24 per dose). Eighteen females per treatment had their reproductive activity scored at 4, 8, 12 and 16 weeks using two ovarian (Graafian follicle and corpus luteum status) and two reproductive tract (uterine and vaginal muscularity and vascularity) parameters that formed a reproductive activity score...

Background: Inflammatory bowel disease (IBD) patients often continue to experience nonspecific gastrointestinal symptoms despite quiescent disease. Unlike non-IBD patients, IBD patients with dyssynergic defecation (DD) may present with various symptoms such as diarrhea, fecal incontinence, constipation, and rectal discomfort. Despite its importance and treatability, DD in IBD patients is not well recognized in practice. We conducted a systematic review and meta-analysis on the prevalence, diagnosis, and management of DD in IBD patients with ongoing defecatory symptoms...

BACKGROUND: Canal wall down (CWD) mastoidectomy has many drawbacks including chronic otorrhea, granulations, dizziness on exposure to cold or hot water and tendency of debris accumulation in the mastoid cavity demanding periodic cleaning. Many of these problems can be solved by reconstruction of the posterior meatal wall (PMW). OBJECTIVES: To assess the results of PMW reconstruction after CWD mastoidectomy for cholesteatoma using bioactive glass (BAG) that is fabricated and built up intraoperatively...

In the current study, laminated chitosan (CS):hydroxypropyl methylcellulose (HPMC) composite sponges were exploited as solid matrices for buccal delivery of tripterine phytosomes functionalized with novel mucopenetrating protamine layer (PRT-TRI-PHY). Tripterine (TRI) is a herbal drug widely investigated as a potential anticancer candidate against various types of cancers. However, clinical use of TRI is handicapped by its low oral bioavailability. To surmount TRI pharmaceutical obstacles, TRI phytosomes (TRI-PHY) were prepared using solvent evaporation technique then coated with a protamine layer via electrostatic assembly process...

PURPOSE: Variability in functional outcome after ileal pouch-anal anastomosis (IPAA) is to a large extent unexplained. The aim of this study was to use MRI to evaluate the morphology, emptying pattern and other pathology that may explain differences in functional outcome between well-functioning and poorly functioning pouch patients. A secondary aim was to establish a reference of normal MRI findings in pelvic pouch patients. METHODS: From a previous study, the best and worst functioning patients undergoing IPAA surgery between 2000 and 2013 had been identified and examined with manovolumetric tests (N = 47)...

A 45-year-old multipara woman was referred due to the rapid enlargement of an asymptomatic pelvic mass that was detected during a regular check up. She had undergone laparoscopic-assisted myomectomy 15 years previously. At the time, the uncontained extraction of an intraligamental myoma with electric power morcellation had been performed. Multimodal imaging revealed a heterogeneous mass in the vesicouterine pouch that was found to be supplied by the left gastro-omental and superior vesical arteries. Although malignancy could not be completely denied, parasitic peritoneal myoma with myxoid degeneration was the most probable diagnosis...

The Tasmanian tiger or thylacine ( Thylacinus cynocephalus ) was an iconic Australian marsupial predator that was hunted to extinction in the early 1900s. Despite sharing striking similarities with canids, they failed to evolve many of the specialized anatomical features that characterize carnivorous placental mammals. These evolutionary limitations are thought to arise from functional constraints associated with the marsupial mode of reproduction, in which otherwise highly altricial young use their well-developed forelimbs to climb to the pouch and mouth to suckle...

BACKGROUND: Guttural pouch mycosis (GPM) is a cause of nasal discharge, dysphagia, and fatal haemorrhage in the horse. OBJECTIVES: To report the complications and success of salpingopharyngeal fistulation in horses with GPM. We hypothesised that creating a direct static opening into the guttural pouch from the pharynx would cause a regression of fungal plaques due to a change in the guttural pouch environment and that this treatment would result in resolution of infection prior to secondary complications...

A 54-year-old woman was admitted to the emergency department with a 2-week history of alimentary vomiting. She had undergone laparoscopic adjustable gastric banding 6 years earlier. CT revealed a mesenteroaxial gastric volvulus and ischemia on the gastric wall. Emergent diagnostic laparoscopy was performed, and severe peritonitis and gastric necrosis caused by volvulation was found. After band removal, a fundal perforation was noted, but a viable lesser curvature enabled laparoscopic sleeve gastrectomy to be performed...

Quinones, which are ubiquitous in nature, can act as sustainable and green electrode materials but face dissolution in organic electrolytes, resulting in fast fading of capacity and short cycle life. We report that quinone electrodes, especially calix[4]quinone (C4Q) in rechargeable metal zinc batteries coupled with a cation-selective membrane using an aqueous electrolyte, exhibit a high capacity of 335 mA h g-1 with an energy efficiency of 93% at 20 mA g-1 and a long life of 1000 cycles with a capacity retention of 87% at 500 mA g-1 ...

2,5-Di-tert-butyl-1,4-bis(2-methoxyethoxy)benzene (DBBB) is studied as an overcharge protecting additive in 1.5 Ah graphite/C-LFP lithium-ion pouch cells for the first time. The elec-trochemical performance demonstrated that the protecting additive remains inert during the extended standard cycling for 4000 cycles as compared with the baseline cell. However, when a 100% overcharge is introduced in the charging protocol, the baseline cell fails rapidly during the first abusive event whereas the cell containing DBBB additive withstands 700 overcharge cycles with 87% capacity retention and no gas evolution or cell swelling was ob-served...
