ABSTRACT

OBJECTIVE: To assess the efficacy and safety of Sildenafil citrate in the treatment of ED in (HD) compared to post-RT patients. PATIENTS AND METHODS: A concurrent cohort prospective study to evaluate the efficacy of Sildenafil in the treatment of ED in 24 HD patients (Group A) and 13 patients with persistent ED one-year post-RT (Group B). The initial dose of Sildenafil was 25 mg, increased to 50 mg if there is an adequate response. An Arabic-translated International Index of Erectile Function (IIEF) questionnaire was completed one week before and after Sildenafil treatment. An IIEF erectile function score of 26 or an improvement of at least 10 points for the total IIEF score was considered a favorable response to Sildenafil. RESULTS: Group A included 22 patients with a mean age of 47.32 ± 7.013 years, whereas Group B included 13 patients with a mean age of 56.87 ± 9.612 years. The overall efficacy rate of Sildenafil was 40.9% and 76.9% in groups A and B, respectively. The post-treatment IIEF5-15 score increased from 11.1 ± 5.99 to 12.5 ± 6.41 (p = .458) and from 11.82 ± 7.534 to 21.91 ± 5.700 (p = .002) in groups A and B, respectively. In both groups, the duration of HD had no impact on ED improvement except in the post-RT non-responder subgroup. Hypertension, gastrointestinal symptoms, and flushing were both groups' most common side effects. CONCLUSION: RT could enhance the response to sildenafil in treating patients with ED. The outcome is better in younger post-RT patients with moderate and severe erectile dysfunction and shorter dialysis duration.

ABSTRACT

OBJECTIVES: Lymphocele formation after kidney transplant is a common complication that causes significant morbidity. In this study, we aimed to evaluate the safety and effectiveness of intraoperative prophylactic povidone-iodine sclerotherapy through the closed suction drain to prevent lymphocele after kidney transplant. MATERIALS AND METHODS: In this retrospective comparative single-institution study, we compared patients who underwent intraoperative prophylactic povidone-iodine sclerotherapy through the closed suction drain (group A) with patients who did not receive sclerotherapy (group B). Patients were treated between September 2017 and July 2023. Atthe end of the kidney transplant surgery, after the closure of the external oblique muscle layer and before skin closure, 10 mL of 10% povidone-iodine in 40 mL of normal saline were instilled via the closed suction drain and dwelled in the cavity for 30 minutes. RESULTS: During the study period, 300 living-related donor kidney transplants were performed. Prophylactic povidone-iodine sclerotherapy was performed in 150 patients (50%).We noted a significantly lower incidence of lymphorrhea and lymphocele in group A. On postoperative days 1 and 5, we noted a significant reduction in drain output in group A (P < .001). One patient in group A and 5 patients in group B required ultrasonography-guideddrainage andpovidone-iodine sclerotherapy. No sclerotherapy-related complications were reported after a median follow-up of 16 months (range, 3-29 months). CONCLUSIONS: Intraoperative prophylactic povidoneiodine sclerotherapy appears to be an easy, safe, and effective procedure for preventing lymphatic complications after living donor kidney transplant.

ABSTRACT

BACKGROUND: To compare donor and recipient outcomes in patients with renal artery and ante-aortic renal vein vs unusual renal vascular anatomy undergoing laparoendoscopic single-site donor nephrectomy (LESSDN). METHODS: A retrospective chart review of the comparative study of donor and recipient outcomes of LESSDN in donors with venous abnormality (n = 28, group A), arterial abnormality (n = 74, group B), and standard donors (n = 248, group C). RESULTS: From September 2016 to August 2022, 350 left LESSDN were performed. The most common anomalies in group A were the retro-aortic and 2 renal veins in 12 patients each. In group B, 72 and 2 patients had 2 and 3 renal arteries, respectively. Operative and warm ischemia times were significantly longer in donors with vascular anomalies. Moreover, patient creatinine on discharge was significantly higher in arterial anomalies; it was 1.61 ± 0.22 compared with 1.26 ± 0.43 and 1.25 ± 0.32 mg/dL for patients with no anomalies and venous anomalies, respectively (P < .001). However, serum creatinine levels recovered after 1 month and were comparable between the study groups. Recipients, operative time, and vascular anastomosis time were significantly longer in recipients with vascular anomaly. Slow graft function was higher in group B (6.9%) than in the other groups. One-year graft survival rates were 96.4%, 94.6%, and 97.1% (P = .496). CONCLUSION: With increased experience, LESSDN in multiple renal arteries and uncommon venous anatomy cases is feasible and safe. Moreover, it does not influence donor or recipient outcomes.

ABSTRACT

The main objective of this research is the water redistribution supply network project, which includes the water transportation company and the water work. The innovative regulatory accounting approach is used to build non-cooperative and helpful game models under government endowments. Different levels and types of government subsidies were then considered in terms of water availability, estimation, and benefit-sharing. Results reveal that water supply and price increase in cycles with the number of sponsors, while the cost of water work falls as sponsorships increase. Despite this, the cost of the water plant remained the same while sponsorship levels remained stable. Although the worth of the water transportation company fluctuates, the more endowments it receives when its value is lower. The appropriateness of the proposed game model was illustrated in the Nile Waterway Water Redirection Task.

ABSTRACT

In this article, we investigate the bioconvection flow of Casson nanofluid by a rotating disk under the impacts of Joule heating, convective conditions, heat source/sink and gyrotactic microorganisms. When Brownian diffusion and thermophoretic effects exist, the Casson fluid is examined. The existing physical problem of Casson nanofluid flow with energy transports is demonstrated under the above considerations in the form of partial differential equations (PDEs). Using the appropriate transformations, the PDEs are converted into non-linear ordinary differential equations (ODEs). The mathematical results are calculated through MATLAB by using the function bvp4c. The problem's results are rigorously examined graphically and described with physical justifications. Velocity fields decrease as the bioconvection Rayleigh parameter rises. The thermal profile and soluteal field of species also magnify with an upsurge in thermophoresis number estimations. The microorganism's fields are decayed by larger microbes Biot number.

ABSTRACT

Nowadays, the world is challenged with highly contagious diseases, one of their preliminary virulence mechanisms is the suppression of innate immunity. Therefore, promoting natural immunity is a good precautionary strategy. we investigated and compared the effects of several natural herbal extracts -Moringa oleifera, Ziziphus spina christi, and Saussurea costus, and chitosan nanoparticles (CS NPs)- as well as conjugated extracts with CS NPs on the immunological parameters of dexamethasone immunosuppressed (IS) male rats. The plant extracts were assessed for total flavonoids, phenolics, and antioxidant activity. The CS NPs and their conjugates were characterized using particles size, zeta potentials, and Fourier-transform infrared spectroscopy analyses. The chemical analysis of the plant extracts, CS NPs, and their conjugates was performed using energy dispersive X-ray fluorescence, and their cytotoxicity was evaluated in human lung fibroblast (WI-38) and human embryonic kidney (HEK-293) cell lines. For in vivo evaluations, 72 adult male rats were divided into 9 groups: control, IS, three plant extracts, CS, and conjugates of the three plant extracts and CS NPs. Oral supplementation (day after day) lasted for 28 days. Liver, kidney, and spleen tissue samples were collected for histopathology and Ki-67 expression analyses. The results revealed that the plant extracts and CS improved the total leukocyte counts, complement 3, complement 4, interferon-gamma, and tumor necrosis factor levels at day 28. However, the plant extract-CS NPs conjugates faster and have higher immunostimulatory effects at day 14. Furthermore, the atrophied white pulp of the spleen induced by dexamethasone was alleviated, and Ki-67 expression was elevated in all the treated groups. Conclusively, the conjugates of Moringa oleifera, Ziziphus spina christi, and Saussurea costus extract with CS NPs demonstrated more potent and rapid immune responses at lower doses and concentrations compared to the plant extracts or CS NPs alone, without causing liver or kidney injuries. Thus, supplementation of these conjugated plant extracts at lower doses and concentrations is recommended to improve immunity while considering safety considerations.

ABSTRACT

Tobacco products are widely recognized as a major contributor to death. Cigarette smoke contains several toxic chemicals including heavy metals particulate causing high health risks. However, limited information has been available on the health risks associated with the heavy metals in cigarettes commonly sold in the Bangladeshi market. This study evaluated the concentrations and potential health risks posed by ten concerned heavy metals in ten widely consumed cigarette brands in Bangladesh using an atomic absorption spectrometer. The concentration (mg/kg) ranges of heavy metals Pb, Cd, Cr, As, Co, Ni, Mn, Fe, Cu, and Zn vary between 0.46-1.05, 0.55-1.03, 0.80-1.2, 0.22-0.40, 0.46-0.78, 2.59-3.03, 436.8-762.7, 115.8-184.4, 146.6-217.7, and 34.0-42.7, respectively. We assume that the heavy metals content among cigarette brands is varied due to the differences in the source of tobacco they use for cigarette preparation. The carcinogenic risks posed by heavy metals follow the order of Cr > Co > Cd > As > Ni > Pb, while the non-carcinogenic risks for Cu, Zn, Fe, and Mn were greater than unity (HQ > 1), except for Fe. The existence of toxic heavy metals in cigarette tobacco may thus introduce noticeable non-carcinogenic and carcinogenic health impacts accompanying inhalation exposure. This study provides the first comprehensive report so far on heavy metal concentration and associated health risks in branded cigarettes commonly sold in Bangladesh. Hence, this data and the information provided can serve as a baseline as well as a reference for future research and have potential implications for policy and legislation in Bangladesh.

ABSTRACT

BACKGROUND: Cadmium (Cd) is a major environmental pollutant and chronic toxicity could induce nephropathy by increasing renal oxidative stress and inflammation. Although vitamin D (VD) and calcium (Ca) prophylactic treatments attenuated Cd-induced cell injury, none of the prior studies measure their renoprotective effects against pre-established Cd-nephropathy. AIMS: To measure the alleviating effects of VD and/or Ca single and dual therapies against pre-established nephrotoxicity induced by chronic Cd toxicity prior to treatment initiation. METHODS: Forty male adult rats were allocated into: negative controls (NC), positive controls (PC), Ca, VD and VC groups. The study lasted for eight weeks and all animals, except the NC, received CdCl2 in drinking water (44 mg/L) throughout the study. Ca (100 mg/kg) and/or VD (350 IU/kg) were given (five times/week) during the last four weeks to the designated groups. Subsequently, the expression of transforming growth factor-ß (TGF-ß1), inducible nitric oxide synthase (iNOS), neutrophil gelatinase-associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), VD synthesising (Cyp27b1) and catabolizing (Cyp24a1) enzymes with VD receptor (VDR) and binding protein (VDBP) was measured in renal tissues. Similarly, renal expression of Ca voltage-dependent channels (CaV1.1/CaV3.1), store-operated channels (RyR1/ITPR1), and binding proteins (CAM/CAMKIIA/S100A1/S100B) were measured. Serum markers of renal function alongside several markers of oxidative stress (MDA/H2O2/GSH/GPx/CAT) and inflammation (IL-6/TNF-α/IL-10) together with renal cell apoptosis and expression of caspase-3 were also measured. RESULTS: The PC group exhibited hypovitaminosis D, hypocalcaemia, hypercalciuria, proteinuria, reduced creatinine clearance, and increased renal apoptosis/necrosis with higher caspase-3 expression. Markers of renal tissue damage (TGF-ß1/iNOS/NGAL/KIM-1), oxidative stress (MDA/H2O2), and inflammation (TNF-α/IL-1ß/IL-6) increased, whilst the antioxidants (GSH/GPx/CAT) and IL-10 decreased, in the PC group. The PC renal tissues also showed abnormal expression of Cyp27b1, Cyp24a1, VDR, and VDBP, alongside Ca-membranous (CaV1.1/CaV3.1) and store-operated channels (RyR1/ITPR1) and cytosolic Ca-binding proteins (CAM/CAMKIIA/S100A1/S100B). Although VD was superior to Ca monotherapy, their combination revealed the best mitigation effects by attenuating serum and renal tissue Cd concentrations, inflammation and oxidative stress, alongside modulating the expression of VD/Ca-molecules. CONCLUSIONS: This study is the first to show improved alleviations against Cd-nephropathy by co-supplementing VD and Ca, possibly by better regulation of Ca-dependent anti-oxidative and anti-inflammatory actions.

ABSTRACT

Musculoskeletal disorders and the stagnation of sitting are among the side effects of excessive sitting in awkward sitting positions. In this study, a developed chair attachment cushion design with an optimal air blowing technique is proposed to eliminate the negative side effects of prolonged sitting. Instantaneously reducing the contact area between the chair and its occupant is the fundamental goal of the proposed design. The fuzzy multi-criteria decision-making approaches represented by FAHP and FTOPSIS were integrated to evaluate and select the optimal proposed design. An ergonomic and biomechanics assessment of the occupant's seating position while employing the novel safety cushion design was validated using simulation software (CATIA). Sensitivity analysis was also used to confirm the design's robustness. Results show that the manual blowing system using an accordion blower was the optimal design concept based on the selected evaluation criteria. In fact, the proposed design provides an acceptable RULA index value for the examined sitting postures and performed very safely in the biomechanics single action analysis.

ABSTRACT

Metals, such as copper and silver, can be extremely toxic to bacteria at exceptionally low concentrations. Because of this biocidal activity, metals have been widely used as antimicrobial agents in a multitude of applications related with agriculture, healthcare, and the industry in general. A large number of microorganisms live in the human environment. if the balance of these creatures in nature is disturbed, the health of the individual and society will be threatened due to the production and emission of unpleasant odors and the reduction of health standards. The presence of microorganisms on textiles can cause adverse effects such as discoloration or staining on textiles, decomposition of fibrous materials, reduced strength, and eventually decay of textiles. Most fibers and polymers do not show resistance to the effects of microbes and by providing growth factors for microorganisms such as the right temperature and humidity, nutrients from sweat and fat from skin glands, dead skin cells as well as materials used in the stage of finishing the textiles causes the rapid growth and spread of various microbes. With the advent of nanotechnology, various industries and human daily life underwent changes. In recent years, increasing research on nanoparticles has led to the production of textiles with greater efficiency and added value. These modified textiles prevent the spread of unpleasant odors, the spread, and transmission of diseases. This article reviews the basics and principles of antimicrobial tetiles, as well as a brief overview of antimicrobial materials and nanostructures with antimicrobial properties.

ABSTRACT

Nanosensors work on the "Nano" scale. "Nano" is a unit of measurement around 10- 9 m. A nanosensor is a device capable of carrying data and information about the behavior and characteristics of particles at the nanoscale level to the macroscopic level. Nanosensors can be used to detect chemical or mechanical information such as the presence of chemical species and nanoparticles or monitor physical parameters such as temperature on the nanoscale. Nanosensors are emerging as promising tools for applications in agriculture. They offer an enormous upgrade in selectivity, speed, and sensitivity compared to traditional chemical and biological methods. Nanosensors can be used for the determination of microbe and contaminants. With the advancement of science in the world and the advent of electronic equipment and the great changes that have taken place in recent decades, the need to build more accurate, smaller and more capable sensors was felt. Today, high-sensitivity sensors are used that are sensitive to small amounts of gas, heat, or radiation. Increasing the sensitivity, efficiency and accuracy of these sensors requires the discovery of new materials and tools. Nano sensors are nanometer-sized sensors that, due to their small size and nanometer size, have such high accuracy and responsiveness that they react even to the presence of several atoms of a gas. Nano sensors are inherently smaller and more sensitive than other sensors.

ABSTRACT

This study investigated the chemotherapeutic effects of 5-fluorouracil (5-FU), metformin (Met), and/or thymoquinone (TQ) single/dual/triple therapies in the HT29, SW480 and SW620 colon cancer (CRC) cell lines. Cell cycle/apoptosis were measured by flow cytometry. The gene and protein expression of apoptosis (PCNA/survivin/BAX/Cytochrome-C/Caspase-3) and cell cycle (CCND1/CCND3/p21/p27) molecules, the PI3K/mTOR/HIF1α oncogenic pathway, and glycolysis regulatory enzymes were measured by quantitative-PCR and Western blot. Markers of oxidative stress were also measured by colorimetric assays. Although all treatments induced anti-cancer effects related to cell cycle arrest and apoptosis, the triple therapy showed the highest pro-apoptotic actions that coincided with the lowest expression of CCND1/CCND3/PCNA/survivin and the maximal increases in p21/p27/BAX/Cytochrome-C/Caspase-3 in all cell lines. The triple therapy also revealed the best suppression of the PI3K/mTOR/HIF1α pathway by increasing its endogenous inhibitors (PTEN/AMPKα) in all cell lines. Moreover, the lowest expression of lactate dehydrogenase and pyruvate dehydrogenase kinase-1 with the highest expression of pyruvate dehydrogenase were seen with the triple therapy, which also showed the highest increases in oxidative stress markers (ROS/RNS/MDA/protein carbonyl groups) alongside the lowest antioxidant levels (GSH/CAT) in all cell lines. In conclusion, this is the first study to reveal enhanced anti-cancer effects for metformin/thymoquinone in CRC that were superior to all monotherapies and the other dual therapies. However, the triple therapy approach showed the best tumoricidal actions related to cell cycle arrest and apoptosis in all cell lines, possibly by enhancing oxidative glycolysis and augmenting oxidative stress through stronger modulation of the PI3K/mTOR/HIF1α oncogenic network.

ABSTRACT

Metallic glass (MG) is a promising coating material developed to enhance the surface hardness of metallic substrates, with laser cladding having become popular to develop such coatings. MGs properties are affected by the laser cladding variables (laser power, scanning speed, spot size). Meanwhile, the substrate surface roughness significantly affects the geometry and hardness of the laser-cladded MG. In this research, Fe-based MG was laser-cladded on substrates with different surface roughness. For this purpose, the surfaces of the substrate were prepared for cladding using two methods: sandpaper polishing (SP) and sandblasting (SB), with two levels of grit size used for each method (SP150, SP240, SB40, SB100). The experiment showed that substrate surface roughness affected the geometry and hardness of laser-cladded Fe-based MG. To predict and optimize the geometry and hardness of laser-cladded Fe-based MG single tracks at different substrate surface roughness, a fuzzy logic control system (FLCS) was developed. The FLCS results indicate that it is an efficient tool to select the proper preparation technique of the substrate surface for higher clad hardness and maximum geometry to minimize the number of cladding tracks for full surface cladding.

ABSTRACT

BACKGROUND: With the global increase in chronic wounds and the paucity of studies on patient experiences at wound care facilities, we assessed the factors associated with satisfaction with wound care services among patients or their caregivers in a Northwest Nigerian outpatient setting. METHODS: Participants were systematically selected from patients or their caregivers attending the General Outpatient Clinic of Aminu Kano Teaching Hospital, Kano, for wound dressing. A structured self-administered questionnaire was used to obtain information regarding their sociodemographic and clinical characteristics and satisfaction with service domains. Data were analyzed using descriptive and inferential statistical methods. RESULTS: There were 170 participants. Their mean age was 31.9±11.4 years, and they were mainly female (55.3%). The overall satisfaction rate was 85.9% (146/170); however, 51.8% and 55.3% of participants were dissatisfied with the advice on home wound care and waiting time, respectively. Employment status, wound location, having sickle cell disease, needing a wheelchair to reach the wound dressing room and perceived availability of a wheelchair were associated with overall satisfaction (P<0.05). The predictors of overall satisfaction were chronic wounds, wound in areas other than the lower limbs/buttocks, and perceived availability of wheelchairs. CONCLUSION: The overall satisfaction rate was high despite service gaps. However, future improvement in patient satisfaction will require addressing challenges such as the waiting time before wound dressing, equipment (e.g., wheelchairs), and staffing.


CONTEXTE: Avec l'augmentation mondiale du nombre de plaies chroniques et le manque d'études sur les expériences des patients aux centres de soin des plaies, nous avons évalué les facteurs associés à la satisfaction des services de soins des plaies chez les patients ou leurs soignants dans une établissement de soins ambulatoires du nord-ouest du Nigeria. MÉTHODES: Les participants ont été systématiquement sélectionnés parmi les patients ou leurs soignants fréquentant la clinique externe générale de l'hôpital universitaire d'Aminu Kano à kano, pour le traitement des plaies. Un questionnaire structuré auto-administré a été utilisé pour obtenir des informations sur les caractéristiques sociodémographiques et cliniciques et leur satisfaction à l'égard des services. Les données ont été analysées à l'aide de méthodes statistiques descriptives et inférentielles. RÉSULTATS: Il y avait 170 participants. Leur âge moyen était de 31,9±11,4 ans, et ils étaient principalement des femmes (55,3 %). Le taux de satisfaction global était de 85,9 % (146/170) ; cependant, 51,8 % et 55,3 % des participants étaient insatisfaits des conseils sur le traitement des plaies à domicile et du temps d'attente, respectivement. Le statut professionnel, l'emplacement de la plaie, le fait d'avoir une drépanocytose, besoin d'un fauteuil roulant pour atteindre la salle de pansements et la disponibilité perçue d'un fauteuil roulant étaient associés à la satisfaction globale (P<0,05). Les facteurs prédictifs de la satisfaction globale étaient les plaies chroniques, les plaies situées dans des zones autres que les membres inférieurs/fesses et la disponibilité perçue des fauteuils roulants. CONCLUSION: Le taux de satisfaction globale était élevé malgré les lacunes des services. Cependant, l'amélioration future de la satisfaction des patients nécessitera relever des défis tels que le temps d'attente avant le pansement des plaies, l'équipement (p. ex., les fauteuils roulants) et la dotation en personnel. MOTS-CLÉS: Patients externes, Caractéristiques des patients, Satisfaction des patients, Soins des plaies, Pansements.

ABSTRACT

BACKGROUND: This study was designed to compare effect of combined use of dexamethasone and honey versus each agent alone in controlling complications associated with removal of impacted mandibular third molar. METHODS: This randomized clinical study included patients suffering from impacted mandibular wisdom teeth. Patients were divided randomly into 4 groups. Group I, control, group II, received dexamethasone injection preoperatively, group III, received honey locally in the wound after extraction, and group IV, received dexamethasone injection preoperatively and topical honey application. All patients were evaluated preoperatively and postoperatively to assess facial edema, interincisal distance, pain, and total analgesic dose used. RESULTS: Significant edema developed in group I than other groups and improved significantly in group II and III on seventh postoperative day, and tenth postoperative day in group I. Insignificant edema developed in group IV. Significant decrease in interincisal distance occurred in all groups on third postoperative day that improved significantly on seventh postoperative days in all groups except group I, it improved on tenth postoperative day. Pain was significantly minimum in group IV than other groups and its maximum degree was in group I. CONCLUSION: Both dexamethasone and honey are an effective way of minimizing swelling, pain, and trismus after removal of impacted lower third molars. Both agents either alone or in combination provide simple, safe, painless, and cost-effective method to eliminate postoperative discomfort. However, dexamethasone or honey can decrease complications related to surgical extraction of mandibular third molar, the simultaneous application of both agents is more effective method in this regard.

ABSTRACT

Cinnamaldehyde, the main phytoconstituent of the cinnamon oil, has been reported for its potential wound healing activity, associated to its antimicrobial and anti-inflammatory effects. In this study, we are reporting on the cinnamaldehyde-based self-nanoemulsifying drug delivery system (CA-SNEDDS), which was prepared and evaluated for its antimicrobial, antioxidant, anti-inflammatory, and wound healing potential using the rat third-degree skin injury model. The parameters, i.e., skin healing, proinflammatory, and oxidative/antioxidant markers, were evaluated after 3 weeks of treatment regimens with CA-SNEDDS. Twenty rats were divided randomly into negative control (untreated), SNEDDS control, silver sulfadiazine cream positive control (SS), and CA-SNEDDS groups. An aluminum cylinder (120 °C, 10-s duration) was used to induce 3rd-degree skin burns (1-inch square diameter each) on the rat's dorsum. At the end of the experiment, skin biopsies were collected for biochemical analysis. The significantly reduced wound size in CA-SNEDDS compared to the negative group was observed. CA-SNEDDS-treated and SS-treated groups demonstrated significantly increased antioxidant biomarkers, i.e., superoxide dismutase (SOD) and catalase (CAT), and a significant reduction in the inflammatory marker, i.e., NAP-3, compared to the negative group. Compared to SNEDDS, CA-SNEDDS exhibited a substantial antimicrobial activity against all the tested organisms at the given dosage of 20 µL/disc. Among all the tested microorganisms, MRSA and S. typhimurium were the most susceptible bacteria, with an inhibition zone diameter (IZD) of 17.0 ± 0.3 mm and 19.0 ± 0.9 mm, respectively. CA-SNEDDS also exhibited strong antifungal activity against C. albicans and A. niger, with IZD of 35.0 ± 0.5 mm and 34.0 ± 0.5 mm, respectively. MIC and MBC of CA-SNEDDS for the tested bacteria ranged from 3.125 to 6.25 µL/mL and 6.25 to 12.5 µL/mL, respectively, while the MIC and MBC for C. albicans and A. niger were 1.56 µL/mL and 3.125 µL/mL, respectively. The MBIC and MBEC of CA-SNEDDS were also very significant for the tested bacteria and ranged from 6.25 to 12.5 µL/mL and 12.5 to 25.0 µL/mL, respectively, while the MBIC and MBEC for C. albicans and A. niger were 3.125 µL/mL and 6.25 µL/mL, respectively. Thus, the results indicated that CA-SNEDDS exhibited significant wound healing properties, which appeared to be attributed to the formulation's antimicrobial, antioxidant, and anti-inflammatory effects.

ABSTRACT

In recent years, significant progress has been achieved in genome editing applications using new programmable DNA nucleases such as zinc finger nucleases (ZFNs), transcription activator-like endonucleases (TALENs) and the clustered regularly interspaced short palindromic repeats/Cas9 system (CRISPR/Cas9). These genome editing tools are capable of nicking DNA precisely by targeting specific sequences, and enable the addition, removal or substitution of nucleotides via double-stranded breakage at specific genomic loci. CRISPR/Cas system, one of the most recent genome editing tools, affords the ability to efficiently generate multiple genomic nicks in single experiment. Moreover, CRISPR/Cas systems are relatively easy and cost effective when compared to other genome editing technologies. This is in part because CRISPR/Cas systems rely on RNA-DNA binding, unlike other genome editing tools that rely on protein-DNA interactions, which affords CRISPR/Cas systems higher flexibility and more fidelity. Genome editing tools have significantly contributed to different aspects of livestock production such as disease resistance, improved performance, alterations of milk composition, animal welfare and biomedicine. However, despite these contributions and future potential, genome editing technologies also have inherent risks, and therefore, ethics and social acceptance are crucial factors associated with implementation of these technologies. This review emphasizes the impact of genome editing technologies in development of livestock breeding and production in numerous species such as cattle, pigs, sheep and goats. This review also discusses the mechanisms behind genome editing technologies, their potential applications, risks and associated ethics that should be considered in the context of livestock.
