This study examined effect of a dietary synbiotic supplement on the concentrations plasma thyroid hormones, expressions heat shock protein 70 (HSP70), and intestinal histomorphology in broiler chickens exposed to cyclic stress (HS). Three hundred sixty day old male Ross 708 chicks were randomly distributed among 3 treatments containing (PoultryStar meUS) at 0 (control), 0.5 (0.5×), 1.0 (1.0×) g/kg. Each treatment contained 8 replicates 15 birds each housed floor pens temperature lighting...

The aim of this study was to determine the impact probiotic feeding and chronic heat stress on meat quality, total lipid phospholipid contents, oxidation, antioxidant capacity, shock protein abundance broiler breast muscle. A 240 male broilers (5 birds per pen) were subjected 4 treatments consisting a 2 × factorial design. Broilers kept at 21-32-21°C for 10 h daily (heat stress, HS) or 21°C (thermoneutral condition) fed regular diet mixed with (250 ppm Sporulin containing 3 strains Bacillus...

This study aimed to determine the influence of finishing diet on beef appearance and lipid oxidation three muscles. A total 18 Angus steers were selected from treatments: grass-finished (USUGrass), legume-finished (USUBFT), grain-finished (USUGrain). After processing, longissimus thoracis (LT), triceps brachii (TB), gluteus medius (GM) steaks evaluated over a 7-d display period. muscle × interaction was observed for instrumental lightness (L*) redness (a*) (P ≤ 0.001). Within each...

Beef flavor has been identified as a driver of consumer acceptability; however, little is known about variability in major United States retail beef cuts. Four cuts (chuck roast; top sirloin steaks; loin and 80/20 ground beef) were obtained from stores (n=30 per cut city) Miami, Los Angeles, Portland, New York, Denver during 2-mo period 2018. Production systems or package claims documented. An expert trained texture descriptive attribute sensory panel evaluated flavors, aromas, textures...

This study was performed to evaluate the effect of probiotic feeding level on meat quality and protein functionality breast muscle from chickens exposed cyclic heat challenge. A total 180 one-d-old male chicks were randomly allocated in 36 floor pens. From Day 15, birds 32°C for 10 h daily until end experiment (Day 46). Three dietary treatments containing different levels (a mixture 4 lactic acid bacteria, 5.0 × 109 cfu/g) prepared; regular diet without (control), with 0.5 g probiotic/kg...

Recent studies describe an emerging role for percutaneous left ventricular assist devices such as Impella CP® rescue therapy refractory cardiac arrest. We hypothesized that the addition of mechanical chest compressions to device assisted CPR would improve hemodynamics by compressing right ventricle and augmenting pulmonary blood flow filling. performed a pilot study test this hypothesis using swine model prolonged arrest.Eight Yorkshire were anesthetized, intubated, instrumented hemodynamic...

Introduction: Bilateral absent cortical N20 somatosensory evoked potentials (SSEPs) at 12 and 24 hours after return of spontaneous circulation (ROSC) can predict poor neurologic outcome in cardiac arrest patients. However, it remains unknown if early SSEPs be used to assess the efficacy neuroprotective therapies arrest. We hypothesized that rate SSEP recovery during first ROSC differentiate brain injury severity. Methods: Eighteen Yorkshire swine (50-60 kg) were subjected 5 (VF-5) or 10...

ObjectivesHeat stress (HS) has long been known to reduce the productivity of broiler chicken, decreasing breast muscle size and protein content, as well damage various tissues including skeletal muscle. Recently, feeding a dietary probiotic supplement broilers suggested alleviate these negative impacts by improving their gut health nutrient absorption. However, little research performed determine effect on meat quality exposed HS, especially concerning oxidative stability attributes....

ObjectivesBeef from cull cows has been traditionally perceived as low-quality/value meat due to its inferior flavor and tenderness. Given the negative consumer perception of highly processed fresh meat, there is a need develop natural post-harvest aging system improve eating quality attributes beef products, particularly cows. Dry practiced for decades traditional butchery process, which also known palatability characteristics. Thus, main objective this study was evaluate impact different...

Background: Percutaneous ventricular assist device (pLVAD) support and Transient aortic balloon occlusion (AO) can preserve cerebral cardiac blood flow during cardiopulmonary resuscitation (CPR), but it remains unclear if pLVAD reduces post-cardiac arrest myocardial dysfunction. Hypothesis: immediately after the return of spontaneous circulation (ROSC) improves early recovery function following prolonged arrest. Aims: Evaluate association between post-ROSC in a swine model Methods: This is...

Abstract Background Percutaneous left ventricular assist device (pLVAD) can provide hemodynamic support during and after cardiac arrest, but it remains unclear if pLVAD reduces post-cardiac arrest myocardial dysfunction. Methods This is an analysis of a subset animals that achieved return spontaneous circulation (ROSC) in study comparing pLVAD, transient aortic occlusion (AO), or both cardiopulmonary resuscitation (CPR) prolonged arrest. AO, were initiated 24 minutes fibrillation (8 min...

Background: It remains unclear if percutaneous left ventricular assist device (pLVAD) reduces post-cardiac arrest myocardial dysfunction.Methods: This is a prespecified analysis of subset animals that achieved return spontaneous circulation (ROSC) in study comparing pLVAD, transient aortic occlusion (AO), or both during cardiopulmonary resuscitation (CPR). Devices were initiated after 24 minutes fibrillation cardiac (8 min no-flow and 16 mechanical CPR). AO was discontinued post-ROSC, pLVAD...

ObjectivesApoptosis is the process of mediated cell death occurring immediately after exsanguination animals. It initiated by release cytochrome C to cytoplasm, ultimately activating caspase 3. Since 3 an enzyme that cleaves calpastatin, a known inhibitor calpain (primary proteolytic enzyme), potential involvement apoptosis in meat tenderness development has been proposed. Previously, we presented higher activity heat shock protein (HSP) 27, which anti-apoptotic function, and greater...
