Rheology and the study of viscoelastic materials are an integral part of engineering and the study of biophysical systems. Tissue rheology is even used in the study of cancer and other diseases. However, the cost of a rheometer is feasible only for colleges, universities, and research laboratories.

Living in an online world: Social media experiences of adolescents and young adults with cancer.

Background: Despite widespread use, little is known about how adolescents and young adults (AYA) with cancer use social media (SM). This research characterized use and self-reported SM experiences among AYA with cancer.

Procedure: AYA, aged 12-26 years, receiving cancer care completed a mixed-methods survey regarding SM experiences.

Experimental aortic aneurysm severity and growth depend on topical elastase concentration and lysyl oxidase inhibition.

Abdominal aortic aneurysm (AAA) formation and expansion is highly complex and multifactorial, and the improvement of animal models is an important step to enhance our understanding of AAA pathophysiology. In this study, we explore our ability to influence aneurysm growth in a topical elastase plus β-Aminopropionitrile (BAPN) mouse model by varying elastase concentration and by altering the cross-linking capability of the tissue. To do so, we assess both chronic and acute effects of elastase concentration using volumetric ultrasound.

Effects of Braiding Parameters on Tissue Engineered Vascular Graft Development.

Tissue engineered vascular grafts (TEVGs) using scaffolds fabricated from braided poly(glycolic acid) (PGA) fibers coated with poly(glycerol sebacate) (PGS) are developed. The approach relies on in vivo tissue engineering by which neotissue forms solely within the body after a scaffold has been implanted. Herein, the impact of altering scaffold braid design and scaffold coating on neotissue formation is investigated.

Domestic and Family Violence, Reproductive Coercion and the Role for Law.

While sexual abuse is increasingly well recognised as a form of domestic and family violence in Australian legal responses, the recognition and response to reproductive coercion is understudied and under-recognised. This article maps the behaviours and concepts associated with reproductive coercion. Focusing on civil protection orders and family law responses, two of the most commonly accessed responses to domestic and family violence, this article considers whether current legislative definitions and case law recognise reproductive coercion as a form of domestic and family violence.

Dietary management, husbandry, and body weights of African elephants (Loxodonta africana) during successful pregnancies at Disney's Animal Kingdom.

Successful pregnancy in African elephants is influenced by biological and environmental factors. For managed elephants many of these factors are set directly or indirectly by their human care takers, including nutrition and husbandry. While African elephants often struggle to conceive and produce healthy offspring under human care, Disney's Animal Kingdom (DAK) has effectively managed six gestations to fruition in three cows.

The connecting health and technology study: a 6-month randomized controlled trial to improve nutrition behaviours using a mobile food record and text messaging support in young adults.

Background: Early adulthood represents the transition to independent living which is a period when changes in diet and body weight are likely to occur. This presents an ideal time for health interventions to reduce the effect of health problems and risk factors for chronic disease in later life. As young adults are high users of mobile devices, interventions that use this technology may improve engagement.

Nondigestible Fructans Alter Gastrointestinal Barrier Function, Gene Expression, Histomorphology, and the Microbiota Profiles of Diet-Induced Obese C57BL/6J Mice.

Background: Obesity is associated with compromised intestinal barrier function and shifts in gastrointestinal microbiota that may contribute to inflammation. Fiber provides benefits, but impacts of fiber type are not understood.

Objective: We aimed to determine the impact of cellulose compared with fructans on the fecal microbiota and gastrointestinal physiology in obese mice.

ESTIMATED COMPOSITION OF DIETS FED TO CAPTIVE BLACK-AND-WHITE RUFFED LEMURS (VARECIA VARIEGATA) AT 33 U.S. ZOOLOGICAL INSTITUTIONS.

Data on captive diets for black-and-white ruffed lemurs (Varecia variegata) are limited. Information on food items used, inclusion amounts, and the chemical composition of diets is needed to improve the management of nutrition-related health problems seen in captive lemurs (e.g.

Experimental and Computational Studies of the Kinetics of the Reaction of Atomic Hydrogen with Methanethiol.

The overall rate constant for H + CH3SH has been studied over 296-1007 K in an Ar bath gas using the laser flash photolysis method at 193 nm. H atoms were generated from CH3SH and in some cases NH3. They were detected via time-resolved resonance fluorescence.

Modulation of the faecal microbiome of healthy adult dogs by inclusion of potato fibre in the diet.

Inclusion of fermentable fibres in the diet can have an impact on the hindgut microbiome and provide numerous health benefits to the host. Potato fibre (PF), a co-product of potato starch isolation, has a favourable chemical composition of pectins, resistant and digestible starch, cellulose, and hemicelluloses. The objective of the present study was to evaluate the effect of increasing dietary PF concentrations on the faecal microbiome of healthy adult dogs.

Commercially available avian and mammalian whole prey diet items targeted for consumption by managed exotic and domestic pet felines: macronutrient, mineral, and long-chain fatty acid composition.

Whole prey diets encourage species-typical behaviors making them popular in the zoo and home setting for captive exotic and domestic felids, respectively. We evaluated macronutrient, mineral, and long-chain fatty acid composition of 20 whole prey items: mice (1-2, 10-13, 21-25, 30-40, and 150-180 days of age); rats (1-4, 10-13, 21-25, 33-42, and >60 days of age); rabbits (still born, 30-45 days, >65 days with skin, and >65 days of age with skin removed); chicken (1-3 days of age, ground adult); duck (ground adult); and quail (1-3, 21-40, and >60 days of age). Composition of whole prey was highly variable (15-40% DM, 34-75% CP, 10-60% fat, and 8-18% ash).

Post-weaning diet affects faecal microbial composition but not selected adipose gene expression in the cat (Felis catus).

The effects of pre- (i.e., gestation and during lactation) and post-weaning diet on the composition of faecal bacterial communities and adipose expression of key genes in the glucose and insulin pathways were investigated in the cat.

Effects of dietary cooked navy bean on the fecal microbiome of healthy companion dogs.

Background: Cooked bean powders are a promising novel protein and fiber source for dogs, which have demonstrated potential to alter microbial composition and function for chronic disease control and prevention. This study aimed to determine the impact of cooked navy bean powder fed as a staple food ingredient on the fecal microbiome of healthy adult pet dogs.

Methodology/principal Findings: Fecal samples from healthy dogs prior to dietary control and after 4 wk of dietary treatment with macro- and micronutrient matched diets containing either 0 or 25% cooked navy beans (n = 11 and n = 10, respectively) were analyzed by 454-pyrosequencing of the 16S rRNA gene.

Alternative dietary fiber sources in companion animal nutrition.

The US has a pet population of approximately 70 million dogs and 74 million cats. Humans have developed a strong emotional bond with companion animals. As a consequence, pet owners seek ways to improve health, quality of life and longevity of their pets.

Apparent total tract macronutrient and energy digestibility of 1- to- 3-day-old whole chicks, adult ground chicken, and extruded and canned chicken-based diets in African wildcats (Felis silvestris lybica).

Our objectives were to evaluate the composition of whole 1- to- 3-day-old chicks (Whole), ground adult chicken (Ground), chicken-based canned diet (Canned), and chicken-based extruded diet (Extruded); and evaluate apparent total tract energy and macronutrient digestibility of these diets by four captive African wildcats (Felis silvestrus lybica) utilizing a Latin Square design. We analyzed diets for macronutrient and mineral (Ca, P, K, Na, Mg, Fe, Cu, Mn, Zn, and S) composition, and screened for potentially pathogenic bacteria. Canned and Extruded diets tested negative for all microbes and met macronutrient and mineral recommendations for domestic cat foods [AAFCO (2012).

Dietary format alters fecal bacterial populations in the domestic cat (Felis catus).

The effects of short-term (5-week) exposure to wet or dry diets on fecal bacterial populations in the cat were investigated. Sixteen mixed-sex, neutered, domestic short-haired cats (mean age = 6 years; mean bodyweight = 3.4 kg) were randomly allocated to wet or dry diets in a crossover design.

The gut microbiome of kittens is affected by dietary protein:carbohydrate ratio and associated with blood metabolite and hormone concentrations.

High-protein, low-carbohydrate (HPLC) diets are common in cats, but their effect on the gut microbiome has been ignored. The present study was conducted to test the effects of dietary protein:carbohydrate ratio on the gut microbiota of growing kittens. Male domestic shorthair kittens were raised by mothers fed moderate-protein, moderate-carbohydrate (MPMC; n 7) or HPLC (n 7) diets, and then weaned at 8 weeks onto the same diet.

Connecting Health and Technology (CHAT): protocol of a randomized controlled trial to improve nutrition behaviours using mobile devices and tailored text messaging in young adults.

Background: Increasing intakes of fruits and vegetables intake, in tandem with reducing consumption of energy-dense and nutrient poor foods and beverages are dietary priorities to prevent chronic disease. Although most adults do not eat enough fruit and vegetables, teenagers and young adults tend to have the lowest intakes. Young adults typically consume a diet which is inconsistent with the dietary recommendations.

Nitrogen metabolism of four raw meat diets in domestic cats.

Little nutritional information has been collected from domestic cats fed raw meat diets. The objective of the present study was to evaluate differences in N metabolism of domestic cats fed raw beef-based diet (66 % crude protein (CP) and 20 % fat), bison-based diet (49 % CP and 39 % fat), elk-based diet (79 % CP and 6 % fat) and horse-based diet (60 % CP and 26 % fat). A total of eight intact adult female cats were fed to maintain body weight in a cross-over design.

A search accelerated correct intensity Fourier transform microwave spectrometer with pulsed laser ablation source.

The ablation of metal surfaces in the presence of a precursor gas produces reaction products which are often difficult to predict and highly dependent on ablation conditions. This article describes the successful development and implementation of a laser ablation source-equipped Fourier transform microwave spectrometer capable of observing 4 GHz regions of spectra in a single data acquisition event. The dramatically increased speed with which regions may be searched, when compared to other high resolution microwave techniques, allows the source conditions to be the prime variable in laser ablation microwave spectroscopic studies.
