Characteristics of Hanwoo cattle and health implications of consuming highly marbled Hanwoo beef
Joo, S.T.,Hwang, Y.H.,Frank, D. Applied Science Publishers ; Elsevier Science Ltd 2017 Meat science Vol.132 No.-
<P>This review addresses the unique characteristics of Hanwoo cattle and potential health implications of consuming highly marbled Hanwoo beef. The Hanwoo breed has high genetic potential for accumulating intramuscular fat (IMF) and producing highly marbled beef. The high level of marbling is achieved through increasing levels of concentrated feed with an extended finishing period. In response to consumer preferences, the level of marbling of Hanwoo beef has been increasing. The IMF content can be manipulated depending on the feeding duration, finishing diet, and genotype. On the other hand, some consumers are expressing concern regarding the consumption of too much animal fat. This review discusses the potential of Hanwoo beef as a dietary source of heart-healthy fats. Highly marbled Hanwoo beef has a high proportion of monounsaturated fatty acid (MUFA) due to the presence of abundant oleic acid. Literature indicates that MUFAs are heart-healthy dietary fats because they can lower low-density lipoprotein (LDL)-cholesterol while increasing high-density lipoprotein (HDL)-cholesterol. Also, recent clinical trials have indicated that highly marbled beef does not increase LDL-cholesterol and consistently increases HDL-cholesterol. Finally, the current work emphasizes that consumption of high oleic acid Hanwoo beef might potentially reduce risk factors for cardiovascular disease, and may become accepted as a healthy well-being food.</P>

To investigate the practical assessing method of pork quality, 302 carcasses were selected randomly to represent commercial conditions and were probed at 24 hr postmortem (PM) by Danish Meat Quality Marbling (MQM), Hennessy Grading Probe (HGP), Sensoptic Resistance Probe (SRP) and NWK pH-K21 meter (NpH). Also, filter paper wetness (FPW), lightness (L*), ultimate pH (pHu), subjective color (SC), firmness/wetness (SF) and marbling scores (SM) were recorded. Each carcass was categorized as either PSE (pale, soft and exudative), RSE (Reddish-pink, soft and exudative), RFN (reddish-pink, firm and non-exudative) or DFD (dark, firm and dry). When discriminant analysis was used to sort carcasses into four quality groups the highest proportion of correct classes was 65% by HGP, 60% by MQM, 52% by NpH and 32% by SRP. When independent variables were combined to sort carcasses into groups the success was only 67%. When RSE and RFN groups were merged so that there were only three groups (PSE, RSE+RFN, DFD) differentiating by color MQM was able to sort the same set of data into the new set of three groups with 80% accuracy. The proportions of correct classifications for HGP, NpH and SRP were 75%, 61% and 35% respectively. There was a decline in predication accuracy when only two groups, exudative (PSE and RES) and non exudative (RFN and DFD) were sorted. However, when two groups designated PSE and non-PSE (RSE, RFN and DFD) were sorted then the proportion of correct classification by MQM, HGP, SRP and NpH were 87%, 81%, 71% and 66% respectively. Combinations of variables only increased the prediction accuracy by 1 or 2% over prediction by MQM alone. When the data was sorted into three marbling groups based on SM this was not well predicted by any of the probe measurements. The best prediction accuracy was 72% by a combination of MQM and NpH.

Purpose: Transanal total mesorectal excision (TaTME) was developed to overcome surgical difficulties experienced in distal pelvic dissection. Concerns have been raised about potential worse postoperative functional outcomes after TaTME. Also, the oncological safety was questioned. This study aimed to describe the functional, surgical, oncological outcomes and quality of life (QoL) after TaTME. Methods: All consecutive TaTME cases for rectal cancer without disseminated disease between December 2016 and April 2019 were included. The Wexner incontinence score, low anterior resection syndrome (LARS) score, fecal incontinence-related QoL, and the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-core questionnaire and 29-item module (EORTC QLQ-C30/CR29) were collected. Kaplan-Meier analysis was used to calculate local recurrence-free survival. Results: Thirty patients were eligible for analysis of which 23 received questionnaires. Response rate was 74%. After a median follow-up of respectively 20.0 and 23.0 months for functional and oncological outcomes, the median (interquartile range) of Wexner incontinence and LARS scores were 9.0 (7.0–12.0) and 33.1 (25.0–39.0). Major LARS was present in 73.3%. Fecal incontinence, general and colorectal-specific QoL subdomains that are associated with poor bowel function scored in line with previously reported data. The 2-year actuarial cumulative local recurrence rate was 3.7% (95% confidence interval, 2.4%–5.0%). Conclusion: TaTME may lead to significant functional impairments. Patients should receive preoperative counseling on this topic and be fully aware of the potential consequences of their treatment. Oncological data were in line with other short- to moderate-term data and did not show alarming results.

Study Design: Radiologic imaging measurement study. Purpose: To assess the accuracy of detecting lateral mass and facet joint injuries of the subaxial cervical spine on plain radiographs using computed tomography (CT) scan images as a reference standard; and the integrity of morphological landmarks of the lateral mass and facet joints of the subaxial cervical spine. Overview of Literature: Injuries of lateral mass and facet joints potentially lead to an unstable subaxial cervical spine and concomitant neurological sequelae. However, no study has evaluated the accuracy of detecting specific facet joint injuries. Methods: Eight spinal surgeons scored four sets of the same, randomly re-ordered, 30 cases with and without facet joint injuries of the subaxial cervical spine. Two surveys included conventional plain radiographs series (test) and another two surveys included CT scan images (reference). Facet joint injury characteristics were assessed for accuracy and reliability. Raw agreement, Fleiss kappa, Cohen’s kappa and intraclass correlation coefficient statistics were used for reliability analysis. Majority rules were used for accuracy analysis. Results: Of the 21 facet joint injuries discerned on CT scan images, 10 were detected in both plain radiograph surveys (sensitivity, 0.48; 95% confidence interval [CI], 0.26–0.70). There were no false positive facet joint injuries in either of the first two X-ray surveys (specificity, 1.0; 95% CI, 0.63–1.0). Five of the 11 cases with missed injuries had an injury below the lowest visible articulating level on radiographs. CT scan images resulted in superior inter- and intra-rater agreement values for assessing morphologic injury characteristics of facet joint injuries. Conclusions: Plain radiographs are not accurate, nor reliable for the assessment of facet joint injuries of the subaxial cervical spine. CT scans offer reliable diagnostic information required for the detection and treatment planning of facet joint injuries.
A Framework for Biodynamic Feedthrough Analysis—Part I: Theoretical Foundations
Venrooij, Joost,van Paassen, Marinus M.,Mulder, Mark,Abbink, David A.,Mulder, Max,van der Helm, Frans C. T.,Bulthoff, Heinrich H. IEEE 2014 IEEE transactions on cybernetics Vol.44 No.9
<P>Biodynamic feedthrough (BDFT) is a complex phenomenon, which has been studied for several decades. However, there is little consensus on how to approach the BDFT problem in terms of definitions, nomenclature, and mathematical descriptions. In this paper, a framework for biodynamic feedthrough analysis is presented. The goal of this framework is two-fold. First, it provides some common ground between the seemingly large range of different approaches existing in the BDFT literature. Second, the framework itself allows for gaining new insights into BDFT phenomena. It will be shown how relevant signals can be obtained from measurement, how different BDFT dynamics can be derived from them, and how these different dynamics are related. Using the framework, BDFT can be dissected into several dynamical relationships, each relevant in understanding BDFT phenomena in more detail. The presentation of the BDFT framework is divided into two parts. This paper, Part I, addresses the theoretical foundations of the framework. Part II, which is also published in this issue, addresses the validation of the framework. The work is presented in two separate papers to allow for a detailed discussion of both the framework's theoretical background and its validation.</P>
