Efficacy of Carcass Electrical Stimulation in Meat Quality Enhancement: A Review

Adeyemi, Kazeem Dauda,Sazili, Awis Qurni Asian Australasian Association of Animal Productio 2014 Animal Bioscience Vol.27 No.3

The use of electrical stimulation (ES) as a management tool to improve meat quality and efficiency of meat processing is reviewed. The basis of the efficacy of ES is its ability to fast track postmortem glycolysis, which in turn stimulates myriad histological, physical, biochemical, biophysical and physiological changes in the postmortem muscle. Electrical stimulation hastens the onset and resolution of rigor mortis thereby reducing processing time and labor and plays a vital role in improving meat tenderness and other meat quality traits. However, ES may have negative impacts on some meat quality traits such as color stability and water holding capacity in some animals. Electrical stimulation is not an end in itself. In order to achieve the desired benefits from its application, the technique must be properly used in conjunction with various intricate antemortem, perimortem and postmortem management practices. Despite extensive research on ES, the fundamental mechanisms and the appropriate commercial applications remained obscured. In addition, muscles differ in their response to ES. Thus, elementary knowledge of the various alterations with respect to muscle type is needed in order to optimize the effectiveness of ES in the improvement of meat quality.

Background Three-dimensional (3D) model printing improves visualization of anatomical structures in space compared to two-dimensional (2D) data and creates an exact model of the surgical site that can be used for reference during surgery. There is limited evidence on the effects of using 3D models in microsurgical reconstruction on improving clinical outcomes. Methods A retrospective review of patients undergoing reconstructive breast microsurgery procedures from 2017 to 2019 who received computed tomography angiography (CTA) scans only or with 3D models for preoperative surgical planning were performed. Preoperative decision- making to undergo a deep inferior epigastric perforator (DIEP) versus muscle-sparing transverse rectus abdominis myocutaneous (MS-TRAM) flap, as well as whether the decision changed during flap harvest and postoperative complications were tracked based on the preoperative imaging used. In addition, we describe three example cases showing direct application of 3D mold as an accurate model to guide intraoperative dissection in complex microsurgical reconstruction. Results Fifty-eight abdominal-based breast free-flaps performed using conventional CTA were compared with a matched cohort of 58 breast free-flaps performed with 3D model print. There was no flap loss in either group. There was a significant reduction in flap harvest time with use of 3D model (CTA vs. 3D, 117.7±14.2 minutes vs. 109.8±11.6 minutes; P=0.001). In addition, there was no change in preoperative decision on type of flap harvested in all cases in 3D print group (0%), compared with 24.1% change in conventional CTA group. Conclusions Use of 3D print model improves accuracy of preoperative planning and reduces flap harvest time with similar postoperative complications in complex microsurgical reconstruction.

Adeyemi, K.D.,Ebrahimi, M.,Samsudin, A.A.,Sabow, A.B.,Sazili, A.Q. Korean Society of Animal Sciences and Technology 2015 한국축산학회지 Vol.57 No.12

Background: Dietary fats can alter the deposition and distribution of body fats in ruminants. The deposition and distribution of body fat play a vital role in the quality of ruminant carcasses and are of great commercial value since they influence the profitability and consumer acceptability of ruminant meat. The current study examined the effects of dietary blend of 80 % canola oil and 20 % palm oil (BCPO) on carcass characteristics, meat yield and accretion of fatty acid (FA) in subcutaneous, omental, perirenal, and mesentery adipose depots and m. supraspinatus (SS) in goats. Methods: Twenty four Boer crossbred bucks (BW $20.54{\pm}0.47kg$) were randomly assigned to diets containing on DM basis 0, 4 and 8 % BCPO, fed for 100 d and harvested. Results: Diet had no effect (P > 0.05) on slaughter weight, dressing percentage, carcass and non-carcass components, meat yield, color, moisture and carotenoid contents and weight of adipose tissues in goats. The proportion of C18:1n-9 and cis-9 trans-11 CLA in the omental, perirenal and SS was higher (P < 0.05) in goats fed 4 and 8 % BCPO compared with the control goats. Dietary BCPO reduced (P < 0.05) the proportion of C14:0 in the omental, perirenal and mesentery depots, C18:0 in the perirenal depot, C16:0 in the SS and C16:1n-7 in the SS, omental and perirenal tissues. Dietary BCPO enhanced the proportion of C18:1 trans-11 Vaccenic and C18:3n-3 in SS and C20:5n-3 in SS and mesentery depot. No significant changes were found in the FA composition of subcutaneous depot. Conclusions: Results indicate that dietary BCPO can be utilized to alter the FA composition of adipose tissues without detrimental effects on carcass characteristics in goats. Nonetheless, dietary BCPO is not an effective repartitioning agent for body fats in goats.

Africans are good in oral transmission of truth and knowledge, which enhance a very powerful use of proverbs and adage. Surprisingly, African proverbs have been neglected in Biblical Hermeneutic discourse on this continent. The paper aims to recall our attention to the important value of Proverbs in the knowledge of the Bible and tends to apply the efficacy of African proverbs in teaching biblical truth, first to African and others. This venture will validate the belief that every aspect of African’s life has a religion connotation. African proverbs’ main concerns relate to every aspect of human life. It is to teach wisdom and moral lessons. Thus they contain, and are used to convey, moral lessons and advice on how to live a good and prosperous life. African proverbs are highly important as a tool for teaching moral and social values, and how to conduct oneself successfully in the business of life. Proverbs have the power to change people’s conduct, because the truths portrayed in them are so plain and unchallengeable that those who understand the morals and advice they contain, feel compelled to conduct their lives in the manner prescribed in the proverbs by the wise elders of old. The work explores some opportunities for using African proverbs as a tool in teaching biblical truth. This experience draws the meaning of the Bible not only to the African readers but every reader.

Evaluation of SSYA10-001 as a Replication Inhibitor of Severe Acute Respiratory Syndrome, Mouse Hepatitis, and Middle East Respiratory Syndrome Coronaviruses

Adedeji, Adeyemi O.,Singh, Kamalendra,Kassim, Ademola,Coleman, Christopher M.,Elliott, Ruth,Weiss, Susan R.,Frieman, Matthew B.,Sarafianos, Stefan G. American Society for Microbiology 2014 Antimicrobial Agents and Chemotherapy Vol.58 No.8

<P>We have previously shown that SSYA10-001 blocks severe acute respiratory syndrome coronavirus (SARS-CoV) replication by inhibiting SARS-CoV helicase (nsp13). Here, we show that SSYA10-001 also inhibits replication of two other coronaviruses, mouse hepatitis virus (MHV) and Middle Eastern respiratory syndrome coronavirus (MERS-CoV). A putative binding pocket for SSYA10-001 was identified and shown to be similar in SARS-CoV, MERS-CoV, and MHV helicases. These studies show that it is possible to target multiple coronaviruses through broad-spectrum inhibitors.</P>

Global climate change can harm food production globally by varying intensity and frequency of rainfall, increment in greenhouse gases, and extreme weather. Although agriculture is the most substantial economic sector in north-central Nigeria, the influence of climate extremes on maize yield is rarely examined. We conducted a comprehensive Spatio-temporal trend analysis for the 27 climate extremes derived using 39-year (1982-2020) daily temperature and rainfall data collected from 25 weather stations. The nine most influential climate extremes were selected using stepwise regression to explain the rainfed maize yield loss. Results showed that precipitation intensity indices generally revealed significant downward annual trends in mostly all the stations. A persistent increase trend in the mean maximum and minimum temperatures and higher magnitudes in all indices except the cold spell duration indicator (CSDI), cool nights (TN10p), and cool days (TX10p). The regressions result of indices (Rx5day, R99p, R10mm, Precptot, CSDI, TXn, TN10p, TN90p, TR20) that have the most substantial relationship with maize yield loss, and a good agreement was seen between the predicted maize yield loss based on the developed regression model and the estimated yield loss. The analysis revealed that the north-central region of Nigeria is extremely vulnerable to severe droughts, which could have a significant impact on water supplies, food security, and thermal discomfort.

Two-stage batch sorber design and optimization of biosorption conditions by Taguchi methodology for the removal of acid red 25 onto magnetic biomass

Akeem Adeyemi Oladipo,Mustafa Gazi 한국화학공학회 2015 Korean Journal of Chemical Engineering Vol.32 No.9

Biomagnetic material (MFC) was synthesized via simple co-precipitation and used as biosorbent for the removal of acid red 25 (AR25) under optimized conditions. The characteristics of MFC were studied using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), vibrating sample magnetometer (VSM), Boehm titration and scanning electron microscopy (SEM). Optimum removal of AR25 was achieved at pH=5.0. The equilibrium data were well described by the Sips and Freundlich models. Taguchi methodology was employed to optimize the biosorption experiments. 411.56mg/g and 96.8% were obtained as the biosorption capacity and removal efficiency, respectively, at the optimum conditions of ionic strength (0.5M), influent volume (300 L) and MFC dosage (4 g). The contact time for removal of 96% AR25 in two-stage batch system is 400.8min which is lower than the single-stage treatment process (895 min).

극한기후 발생이 미관개지역 옥수수 생산량 감소에 미치는 영향

Climate change is threatening global food production by instigating hot and dry spells of varying intensity and frequency driven by the increased atmospheric concentration of greenhouse gasses. Agriculture is the primary driver of the economy in north-central Nigeria, however, the influence and contribution of climate extremes in inducing maize yield losses are not well-reported. In this study, 27 agriculturally related climate extremes indices were derived using a 39-year (1982-2020) daily temperature and rainfall data collected from 25 weather stations. Stepwise regression was used to discern the nine most influential climate extremes explaining the rain-fed maize yield losses. For all the weather stations, gradual drying was noted based on the declining trends in most of the rainfall-related climatic extremes. Most of the temperature-derived extremes showed notably higher change rates except for the cold spell duration indicator and cool nights. The selected climatic extremes from stepwise regression analysis showed good predictive capability of maize yield losses. The study showed that north-central Nigeria is particularly susceptible to severe droughts and heat waves which can seriously deteriorate sustainable maize production in the future.

Objectives: Quality of life (QoL) studies provide information about the impact of disease, the treatment of symptoms, and outcomes following treatment. The present study aims to evaluate the postoperative QoL of patients treated for oral cancer in a Nigerian government tertiary hospital. Materials and Methods: A prospective study on consenting patients with oral cancer was undertaken at Aminu Kano Teaching Hospital, Kano, Ni- geria. The subjects completed the University of Washington QoL (UW-QoL) questionnaire one day prior to surgery and postoperatively after 7 days, 1 month, 3 months, and 6 months. Results: Sixty-eight patients with oral cancer were recruited. Of these, 38 were males, and 30 were females (male : female, 1.3 : 1). Twenty-four pa- tients (12 males and 12 females) underwent surgery and completed postoperative QoL assessment using the UW-QoL questionnaire. Preoperative QoL mean score was 2.21, while postoperative mean scores after 1 week, 1 month, 3 months, and 6 months were 3.67, 3.46, 2.82, and 2.61, respectively. Conclusion: An improvement in QoL following surgical treatment for patients with oral cancer was observed. ‘Appearance,’ ‘recreation,’ and ‘chewing’ were identified as the most important determinants of postoperative QoL in patients with oral cancer in our study.

COVID-19 vaccines development in Africa: a review of current situation and existing challenges of vaccine production

Olawale Adeyemi 대한백신학회 2022 Clinical and Experimental Vaccine Research Vol.11 No.3

With the growing concern on the evolution of vaccine development in Africa, I congratulate Lamptey et al. [1] on their coronavirus disease 2019 (COVID-19) special article titled “COVID-19 vaccines development in Africa: a review of current situation and existing challenges of vaccine production.” Indeed, a critical gap in vaccine production on the continent is largely responsible for the vaccine inequity. In their piece, the impressive summarization of challenges faced in vaccine development in Africa is indeed a call to action for policymakers and leaders in the health systems on the continent. As the presence of available vaccines has been proven to reduce infections [2]. While structural aspects such as limitations in the cold-supply chains, lack of access to vaccination clinics in underserved areas, digital constraints and a competition for sparsely available appointments could be other constraints faced even after the mitigation of the production challenges are tackled [3]. The authors pointed out that there is a lag in Africa in reduction of COVID-19 burden cases by vaccination [1]. If the challenges of vaccine production in Africa are surmounted, and African nations come up with their own candidates, a major hurdle could be vaccine wastage of available doses. Today, African nations account for some of the lowest COVID-19 vaccination rates worldwide; Nigeria with 6.5% fully vaccinated, Tanzania 5.1%, Cameroon 4.5%, Ethiopia 18.5%, and Kenya 15.6% [4]. The readiness to get vaccinated is greatly influenced by a mistrust of the authorities [5]. With the development of a suitable candidate, vaccine hesitancy on the continent could largely account for wastage of vaccine doses. In addition to strategies to develop COVID-19 vaccine candidates in Africa, it is also imperative that issues that create a mistrust between the population and the health authorities/governments are addressed, to witness a full acceptance of the developed vaccine and compliance. This can avert any possibilities of vaccine wastage if a suitable candidate is developed on the continent. While the push for the development of a pan-African vaccine project is ongoing, community engagement should be used as a measure to restore the confidence of the public. By the use of trusted community figures, confidence in potential developed vaccines in Africa can be increased.
