Influence of Climate Change On Marine Species and Its Solutions
Authors: Wang Zhengjie 
Published: April 2022

Abstract
Marine species are the major components of living organisms on the Earth that have dominated nearly 90 percent of the habitat of Earth. Climate changes have changed the distribution of the marine species among the world and causing extinctions and eventually greatly impacts the whole marine ecosystem. This paper is going to discuss the impacts of climate change on marine species and what humans could do to protect the marine species under the change of the climate. This paper first introduces the global background about the climate change and how does it affects marine species. Then evaluates the whole systems to three smaller parts: fish industry, coral reefs and seagrass. The protection of coral reef and seagrass habitats are necessary to maintain the marine ecosystem. Finally the paper proposals several solutions to minimize the impacts of climate change on marine species. The advanced technology, government support and volunteer works would be essential to save the marine species from the undergoing life threatening situation. From now on, humans should stand together to protect our common habitat and save other species who share the Earth with humans. This paper is important because it evaluates the recent conditions of marine species under the climate change and it explores the potential solutions to solve the ongoing issues.

Abstract
In this study, droplet impact on a solid surface with obstacles occurring in many technological processes was numerically analyzed. The simulation of the hollow droplet impact on to solid surface used the volume of fluid method. A hollow droplet consists of a liquid shell enclosing an air cavity. The hollow droplet impact onto the surface has an obstacle with a different ratio of D/h and diameter of obstacle at three different speeds. It is found that the obstacle made dual jet in some cases. The length of the counter jet decreased with increased the dimension of the obstacle that the maximum and minimum length of the jet is been in case 1 at impact velocity 10 m s−1 and case 3 in V = 5 m s−1. Spread factor (f) increased 34.61% and 44.31% when impact velocity changed 1 m s−1–5 m s−1 and 10 m s−1 respectively.
Self-made transparent optoacoustic detector for measurement of skin lesion thickness in vivo

Published: April 2022

Abstract
In skin cancer diagnosis and treatment, one of the key factors is tumor depth, which is connected to the severity and the required excision depth. Optoacoustical (OA) imaging is a relatively popular technique that provides information based on the optical absorption of the sample. Although often demonstrated with ex vivo measurements or in vivo imaging on parts of small animals, in vivo measurements on humans are more challenging. This is presumably because it is too time consuming and the required excitation pulse energies and their number exceed the allowed maximum permissible exposure (MPE). Here, we demonstrate thickness measurements with a transparent optoacoustical detector of different suspicious skin lesions in vivo on patients. We develop the signal processing technique to automatically convert the raw signal into thickness via deconvolution with the impulse response function. The transparency of the detector allows optical excitation with the pulsed laser to be performed perpendicularly on the lesion, in contrast to the conventional illumination from the side. For validation, the measured results were compared to the histological thickness determined after excision. We show that this simple transparent detector allows to determine the thickness of a lesion and thus, aid the dermatologist to estimate the excision depth in the future.
Finite element analysis of a hybrid corrugated hip implant for stability and loading during gait phases
Authors: Gupta Vivek , Chanda Arnab 
Published: April 2022

Abstract
Implants used in total hip replacements (THR) exhibit high failure rates and up to a decade of operational life. These surgical failures could be mainly attributed to the improper positioning, post-surgical stability and loading, of the implants during different phases of the gait. Typically, revised surgeries are suggested within a few years of hip implantation, which requires multiple femoral drilling operations to remove an existing implant, and to install a new implant. The pain and trauma associated with such procedures are also challenging with the existing hip implants. In this work, we designed a novel corrugated hip implant with innovative dimensioning as per ASTM standards, and grooves for directed insertion and removal (using a single femoral drilling and positioning operation). Biocompatible titanium alloy (Ti6Al4V) was chosen as the implant material, and the novel implant was placed into a femur model through a virtual surgery to study its stability and loading during a dynamic gait cycle. A detailed mesh convergence study was conducted to select a computationally accurate finite element (FE) mesh. Tight fit and frictional fit attachment conditions were simulated, and the gait induced displacements and stresses on the implant, cortical and cancellous bone sections were characterized. During walking, the implant encountered the maximum von-Mises stress of 254.97 MPa at the femoral head. The analyses indicated low micro-motions (i.e., approximately 7 μm) between the femur and implant, low stresses at the implant and bone within elastic limits, and uniform stress distribution, which unlike existing hip implants, would be indispensable for bone growth and implant stability enhancement, and also for reducing implant wear.

Abstract

OBJECTIVES
The aim of this study was to determine the proportion of patients undergoing open arch repair who would be anatomically suitable for multi-branched endovascular arch repair.

METHODS
This study was a single-centre review of patients undergoing open arch repair between 2000 and 2020. Anatomical feasibility was determined by comparing arch measurements to the anatomical criteria of the Zenith® double and triple inner branched-arch endografts (Cook Medical) and the Relay® double arch branched device (Terumo-Aortic).

RESULTS
Ninety (90) patients were included in this study, with 43/90 presenting degenerative aneurysm. The distance between the sinotubular junction and the brachiocephalic trunk measured 114 ± 30 mm on the outer curvature, and the maximum diameter of the proximal landing zone (PLZ) was 41 ± 11mm. A total of 42/90 patients (47%) were anatomically suitable for at least 1 stent graft and 29/90 patients (32%) were eligible for a triple-branched endograft. The most important determinant factors of anatomical suitability were the PLZ diameter (Cramer’s V = 0.743, P &lt; 0.001) and length (Cramer’s V = 0.777, P &lt; 0.001).

CONCLUSIONS
This study shows that the proportion of patients who may be anatomically suitable for branched-arch repair remains limited. The PLZ dimensions tend to be the most important anatomical limitations and should receive more emphasis in the development of branched-arch devices.
Breeding an underutilized fruit crop: a long-term program for Hylocereus
Authors: Tel-Zur Noemi 
Published: April 2022

Abstract
This review describes three decades of introduction, agro-technology development, breeding and selection of Hylocereus species, known as pitaya or dragon fruit, as an example of a holistic program aimed to develop the horticultural potential of a perennial underutilized fruit crop. Interspecific homoploid and interploid crosses and embryo rescue procedures produced improved hybrids, some of which have been released to farmers. Molecular tools and morphological and phenological comparisons between the parental species and the resulting hybrids provided valuable information on dominant/recessive traits and on genetic relationships that could be exploited for further hybridizations. In addition, Hylocereus were crossed with species of the closely related genus Selenicereus, producing valuable intergeneric hybrids. In situ chromosome doubling resulted in the production of autopolyploid lines, from which an understanding of the effect of increased ploidy on fruit traits and metabolomic profiles was obtained. Gamete-derived lines were produced, adding to our biobank homozygote lines that were subsequently used for further hybridization. Spontaneous chromosome doubling occurred in haploid gamete-derived Hylocereus monacanthus lines and in interspecific interploid Hylocereus megalanthus × H. undatus hybrids obtained from an embryo rescue procedure, resulting in plants with double the expected ploidy. Challenging technical problems were addressed by the development of protocols for DNA isolation, flow cytometry, in situ chromosome doubling, androgenesis, gynogenesis and embryo rescue following interspecific and interploidy crosses. Current research leading to the development of genomics and molecular tools, including a draft genome of H. undatus, is also presented. Perspectives for further development of Hylocereus species and hybrids are discussed.

Abstract
A total of 264 litters corresponding to 2,497 nursery pigs were used in a 40-d trial to determine the effect of floor feeding pelleted creep feed or lactation feed on the growth performance and morbidity and mortality of pigs after weaning. Treatments were applied in the farrowing house for 4-d prior to weaning and consisted of a control (no creep), standard (0.32 cm) creep pellet, large (1.27 cm) creep pellet, or sow lactation feed in meal form. For each treatment, approximately 227 g of creep feed per day equally divided into 2 feedings was provided on the mat in farrowing stalls. At weaning, pigs were transported to the nursery facility and randomized to pen within creep feeding treatment. A total of 96 pens (48 feeders) were used, with one barrow pen and one gilt pen per feeder. Thus, feeder (2 pens) was the experimental unit. There were 26 pigs per pen and 12 replications per treatment. During week 1 post-weaning, pigs fed standard or large pellet creep feed had increased (P &lt; 0.001) ADG compared with pigs fed sow lactation feed or no creep feed. This was not driven by improved ADFI but rather G:F (P &lt; 0.001). No differences in growth performance were observed throughout the remainder of the nursery period. Overall, on a per pig placed basis, pigs fed large pellet creep feed had increased ADG (P &lt; 0.05) and improved G:F (P &lt; 0.05) compared with pigs fed sow lactation feed, with the other 2 treatments intermediate. This response was a direct reflection of decreased (P &lt; 0.05) total mortality and removals for pigs fed large pellet creep feed. In summary, floor feeding large pellet creep feed starting 4-d preweaning improved nursery pig growth performance and fallout rates compared with creep feeding sow lactation feed, with standard pellet creep feed or no creep feed having an intermediate effect.

Published: April 2022

Abstract
To evaluate the effects of lactylate and Bacillus subtilis on growth performance, complete blood cell count, and microbial changes, 264 weaning pigs were assigned to 4 treatments (1) control (Con) basal diets that met the nutrient requirement for each phase, (2) 0.2% lactylate (LA), (3) 0.05% Bacillus subtilis strains mixtures (BM) providing 2 x 105 CFU/g of complete feed, or (4) the combination of LA and BM (LA+BM) added to the control basal diet at their respective inclusion rates in each of the 3 phases. Dietary lactylate tended to increase weight gain, significantly increased feed intake, and reduced fecal total E. coli and enterotoxigenic E. coli counts during Phase 1. Pigs fed Bacillus subtilis had a greater gain to feed ratio (G:F) during Phases 1 and 2. Pigs fed lactylate had an increased peripheral absolute neutrophil count on D14 but a decreased eosinophil percentage. Pigs fed Bacillus subtilis had an elevated peripheral total white blood cell count at study completion. The addition of lactylate increased microbiota richness, reduced E. coli, and increased Prevotella, Christensenellaceae, and Succinivibrio. Bacillus subtilis supplementation-enriched f_Ruminococcaceae_unclassified and S24-7_ unclassified had positive relationships with feed efficiency. Collectively, these findings suggested that lactylate can be added to diets to balance gut microbiota and improve growth performance during the early postweaning period. The combination of lactylate and Bacillus subtilis strains exerted a synergic effect on the growth performance of nursery pigs.

Published: April 2022

Abstract
A total of 695 barrows (DNA 200×400; initially 5.9 ± 0.02 kg) were used in 2 groups in a 28-d study to evaluate the effects of dietary calcium carbonate level on nursery pig growth performance and fecal dry matter. Upon arrival to the research facility, pigs were randomly assigned to pens with 5 pigs/pen, and pens were allotted to 1 of 5 dietary treatments with 27 or 28 pens/treatment. Dietary treatments were formulated to provide 0, 0.45, 0.90, 1.35, and 1.80% calcium carbonate added at the expense of corn, which resulted in total Ca of 0.49, 0.66, 0.84, 1.01 and 1.18%, respectively. All diets were formulated to contain 0.68% total P and 0.59% STTD P. Diets were fed in 2 phases with treatment diets fed from d 0 to 14 and a common diet fed from d 14 to 28. Treatment diets were fed in meal (group 1) and pellet (group 2) form. Feces were collected from 3 pigs/pen and dried to calculate fecal dry matter. There was no evidence for a treatment×group interaction and thus, groups were combined. From d 0 to 14 (treatment period), ADG (P = 0.010), d 14 BW (P = 0.006), and G:F (P = 0.010) decreased linearly as calcium carbonate increased. There was no evidence for a difference in ADFI (P &gt; 0.10) between treatments. For fecal dry matter, there was a tendency for a quadratic response (P = 0.091) with the highest and lowest calcium carbonate diets having the greatest dry matter. Subsequent performance from d 14 to 28 was not influenced by previous treatment (P &gt; 0.10). In summary, increasing dietary calcium carbonate from 0 to 1.80% decreased ADG and G:F in pigs the first 14-d after weaning.
164 Awardee Talk: Influence of Ingredient Quality and Diet Formulation on Amino Acid Digestibility and Growth Performance of Poultry and Swine
Authors: Dunmire Kara M , Stark Charles R , Paulk Chad B 
Published: April 2022

Abstract
Ingredient varieties and heat processing can influence nutrient utilization for monogastric species. Objective 1 determined the influence of SBM quality on AA digestibility and growth performance of broilers. Treatments consisted of 1 of 4 soybean sources varying in CP content and processed into SBM; 2 sources from a similar region were either commercially or experimentally solvent extracted. Broilers fed commercially processed SBM had improved (P &lt; 0.05) AA digestibility compared with experimentally processed SBM from a similar region. Increasing CP content increased AA digestibility. Broiler d18 BW improved (P&lt;0.05) in broilers fed conventionally processed SBM compared with experimentally processed SBM. Feed intake improved (P &lt; 0.05) when broilers were fed conventionally processed SBM compared with experimentally processed SBM with experimentally processed SBM from a similar source intermediate. Objective 2 determined the effects of diet formulation and pelleting on AA digestibility and growth performance of swine. Diets were fed in mash or pelleted form and formulated with low or high crystalline AA and low or high RS (reducing sugars; DDGS and bakery meal). There was no feed form × crystalline AA × RS interaction observed for SID of AA. For main effects of feed form, the SID of total AA, CP, and indispensable AA increased (P &lt; 0.042) in pigs fed pelleted diets compared with mash diets. Average daily feed intake decreased (P = 0.001) and G:F and caloric efficiency improved (P = 0.001) in pigs fed pelleted diets compared with mash diets. Pigs fed diets with high crystalline AA had increased (P &lt; 0.024) ADFI compared with those fed diets with low crystalline AA. Pigs fed high RS diets had decreased (P &lt;0.041) ADG, ADFI, G:F, and caloric efficiency compared with those fed low RS. Results concluded that pelleting diets with increased crystalline AA or RS did not lead to a reduction in AA digestibility or affect the pigs’ response to pelleting.
208 Nutrient Restriction During Late Gestation Alters Beef Heifer Colostrum Composition

Published: April 2022

Abstract
We hypothesized that late gestational nutrient restriction of beef heifers would decrease nutrient partitioning to the mammary gland, resulting in less colostrum nutrient availability for neonatal calves. Fall-calving Hereford-SimAngus heifers (single-sired; BW: 451 ± 28 [SD] kg; BCS: 5.4 ± 0.7) bred to a single sire were individually fed 100% (control; n = 12) or 70% (nutrient restricted; NR; n = 13) of NASEM net energy and metabolizable protein requirements for maintenance, pregnancy, and growth from d 160 of gestation to calving. Diets were based on chopped sorghum sudan hay (1.74 Mcal ME, 6.66% CP, 72.0% NDF; DM basis) supplemented to meet targeted nutritional planes. Calving was observed for all females, and total colostrum from one rear quarter was collected pre-suckling (50.5 ± 17 min [SD] postpartum). Colostrum nutrient composition was determined by colorimetric assays run on a UV-visible light microplate reader. Data were analyzed with treatment, calving date, and calf sex (when P &lt; 0.25) as fixed effects. We have previously reported that single-quarter colostrum weight and volume were 40% less (P = 0.04) in NR compared with control heifers. Colostrum lactose concentration was not affected (P = 0.32) by treatment, but yield differences resulted in 46% less (P = 0.03) total single-quarter colostrum lactose in NR than control. Colostrum from NR heifers had 36% greater (P = 0.004) protein concentration than control, but greater colostrum yield of control heifers allowed for total protein to be unaffected (P = 0.57) by treatment. Nutrient restricted heifers had 23% less (P = 0.04) colostrum urea N concentration and 60% less (P = 0.01) total colostrum urea N than control. Late gestational nutrient restriction (P ≥ 0.59) did not affect colostrum triglyceride concentration or total. In summary, energy and protein restriction had disparate effects on nutrient partitioning to colostrum in primiparous beef females.

Abstract
The transmission of passive immunity from the sow to the neonate piglets through colostrum is crucial for their future development. The aim of this experiment was to demonstrate that feeding the live yeast Saccharomyces cerevisiae boulardii CNCM I-1079 (SCB) increases the immunoglobulin G (IgG) concentration in colostrum. In total, 620 colostrum samples were taken from mixed-parity sows (1-9) in 11 farms in Colombia. There were 2 treatments: control (CON; standard feed in gestation and lactation), and SCB (CON + 1 × 109 colony forming units (CFU)/kg, fed from 3 weeks before the expected farrowing date). The samples were taken within the first 4 hours after the birth of the first piglet, from both sides of the teats of the sow, and immediately analyzed with a MA871 refractometer to obtain a °Brix value. Furthermore, each value was attributed to 1 of the 4 following categories regarding IgG concentration: Very good, Adequate, Limited, and Poor. Data were analyzed with SPSS Statistics 26.0 (IBM) and submitted to an analysis of variance with farm as random effect, parity rank and treatment as fixed effects, and their interactions. However, no interaction was found between any of the variables studied. Colostrum from sows in the SCB treatment displayed a higher °Brix value (P &lt; 0.001) than the 1 from sows in the CON treatment. Additionally, the percentage of sows fitting the categories Very good and Adequate was greater in the SCB treatment than in the CON, and the one fitting the categories Limited and Poor was greater in the CON treatment than in the SCB. It is concluded that supplementing sows with Saccharomyces cerevisiae boulardii CNCM I-1079 from 3 weeks before farrowing increases IgG concentration in colostrum, helping the neonate piglets to acquire the passive immunity necessary to improve later performance.

Abstract
Quillaja saponin is derived from the soap bark (Quillaja saponaria Molina) tree, contains a triterpenoid (non-steroidal) sapogenin structural component and exhibits a variety of effects when used as a feed additive. Thus, we aimed to investigate the effects of dietary supplementation of Quillaja saponin and fructooligosaccharide alone or in combination on the growth performance, nutrient digestibility, fecal microbial, and fecal noxious gas emissions in growing pigs. A total of 100 pigs [Duroc × (Landrace × Yorkshire) average body weight (BW) of 23.83 ± 1.95] were randomly allotted into 1 of 4 dietary treatment groups according to initial BW and sex (5 replicate/ treatment, with 3 gilts and 2 barrows per pen) in a 56-d trial. The treatments included a basal diet as negative control (NC), QS diet (QS, NC+ 0.2% QS), a FOS diet (FOS, NC+ 0.10% FOS), and a QS plus FOS diet (QSFOS, NC+ 0.2% QS+ 0.10% FOS). Pigs fed diet supplemented with QS, FOS, and QSFOS resulted in increased (P &lt; 0.05) average daily gain and average daily feed intake during d 28-56 and 0-56, as well as improved the digestibility of dry matter and nitrogen during day 56 compared with NC. On d 28 and 56, there was an increase (P &lt; 0.05) in body weight in the treatment’s groups compared with NC. The fecal Lactobacillus counts was increased and a reduction (P &lt; 0.05) in fecal E. coli counts and HN3 and CO2emission from the feces was observed from pigs fed QS, FOS, and QSFOS supplemented diets. Dietary QS, FOS, and QSFOS supplementation has beneficial effects on growth performance, nutrient digestibility, fecal microbial, and noxious gas emissions in growing pigs.
