Background: Transcatheter arterial embolization can be used for patients with recurrent bleeding from the upper gastrointestinal tract after failed endoscopic treatment. Our aim to identify the clinical and technical factors that influenced the outcome of transcatheter embolization for therapy of upper gastrointestinal bleeding after failed surgery or after failed endoscopic treatment in high risk surgical patients. Methods: We performed a prospective study to analysis of the 15 patients who underwent Transcatheter arterial embolization for nonvariceal upper gastrointestinal bleeding at Alshifa hospital from January 2015 to March 2019. The following variables were recorded: demographic data, time from bleeding start to TAE, units of packed red cells before TAE and units of packed plasma before Transcatheter arterial embolization and we analysis 30 days rebleeding rates and mortality. Results: Patients treated with Transcatheter arterial embolization (median age: 62 years, range: 14–79 years).The technical success rate of the embolization procedure was 100%. Time from bleeding start to TAE was 2.1 (1-4) days , units of packed red cells before Transcatheter arterial embolization was 12.8 (4-22) packed and units of packed plasma was 3.2 (2-5) packed. Following 30 days after embolization, 2 (13%) patients had repeated bleeding and 3 (20.0%) patients died. Conclusion: In our experience, arterial embolization is a safe and effective treatment method for upper gastrointestinal bleeding and a possible alternative to surgery for high-risk patients.

Haemophagocytosis is a dysregulated immune condition characterised by both inflammation and uncontrolled activation of macrophages and T-cells, which causes aberrant cytokine release, leading to cytokine storm [1] it can be primary or secondary, depending upon the etiology. 

Emerging evidence indicates that micronutrient deficiency could play a significant role in the pathogenesis and progression of many chronic diseases including diabetes mellitus, hypertension, obesity, dyslipidemia, hyperuricemia, kidney disease, cancer, anemia and other cardio-metabolic and neurodegenerative diseases through the induction of Insulin resistance (IR). However, there are still gaps in our scientific knowledge regarding the links between micronutrient deficiencies, IR, and cardio metabolic disorders. This review provides current information on recent advances and a global perspective regarding the relationship between micronutrient deficiency, IR, and cardio metabolic disorders. Empirical evidence indicates that deficiencies in either micronutrients associated with insulin activity (such as Chromium, manganese, magnesium, and iron) or antioxidant enzyme cofactors (such as vitamin A, copper, zinc, and manganese) could impact several physiological processes leading to a cascade of metabolic and biochemical derangements such as B-cell apoptosis, loss of islet cell mass, defective tyrosine kinase activity, oxidative stress, pancreatic β-cell dysfunction, reduction in lean body mass, defective insulin signaling mechanism, elevated protein kinase C activity, and excess intracellular calcium. Collaboratively, these states of metabolic malfunctioning are associated with IR, which triggers the onset of many cardio metabolic diseases. Undoubtedly, the prevention of micronutrient deficiency may indeed ameliorate the incidence of IR and cardio-metabolic disorders in those at risk and in the general population.

Two experimental feeding trials were conducted concurrently to study the growth response of African catfish Clarias gariepinus fingerlings to graded levels (0, 5, 10, 15 or 20%) of clupeids in Danish fish meal (DFM) based diets. Chemical analysis of the DFM and clupeids fish meal (CFM) was carried out. Completely randomized design with triplicated groups of fingerlings were used for both trials in an indoor and out-door concrete tanks for six and twelve weeks respectively. The study aimed at achieving a cost effective fish meal from local aquatic resources (clupeids fish) highly prolific and abundant in Nigeria water bodies to replace foreign fish meal in West Africa Region. A project supported by West African Agricultural Productivity Project (WAAPP) in NIFFR, Nigeria. The results of proximate, amino acid profile, mineral and fatty acid composition analysis of CFM indicated values which are very close to those of the DFM. The proximate analysis revealed CFM to contain 70.6% crude protein while DFM contains 72%. There were no significant difference between the treatments with respect to final weight, feed consumed, feed conversion ratio, digestibility and survival (P>0.05) although there was significant difference in specific growth rate (P<0.05) with the highest value obtained in the diets with both fish meal at ratio 1:1. There were no significant difference in haematological parameters (P>0.05). However the lymphocytes were high in all the groups which might not be particularly due to the treatments. The high proliferation of the body defence cells by the fish could be a mechanism of survival in the aqua-medium which is likely to be high in microbial load due to waste materials. Feed Cost/Kg for DFM was N260.16 while for CFM was N227.16. The results of chemical analysis and feeding trials indicated positive replacement of the DFM with CFM in fish feeds without negative effect on growth performance

During the last three decades, there has been an interesting debate on the intake of A1 ‘like” milk and incidence of type 1 diabetes (T1D) in genetically predisposed individuals. The epidemiological, ecological and case-control studies have concrete pieces of evidences in favor of the hypothesis that is further supported by animal trials in mice and rat and in vitro trials on cell lines. But on the other hand, European Food Safety Authority reported that there isn’t sufficient data to draw a final recommendation at this stage in terms of contradictory results, lack of cause-effect relationship and being a mere suggestive evidence [1]. However, the report itself states that these studies are strong enough to formulate a concrete hypothesis and further research is needed to confirm the same. Keeping in view the published data in favor of the hypothesis and the counter-arguments, it is suggested that further research with well-designed animal and in vitro trials with intact proteins and peptides is needed to fully confirm the hypothesis. Until the issue is fully resolved, it’s the personal choice of the individuals at risk to T1D (genetically predisposed) to either remove A1 “like” or increase the A2 “like” milk from their diet. 

A mucoso-respiratory highly contagious disease; COVID-19, has led to tremendous global health and economy damages. This virus could be dampened through home use of fermented bio food material. Fermented millet flour (ibyer) is an indigenous non-alcoholic gruel made from cereals either (maize, sorghum and millet). It is prepared by cooking reconstituted cereal flour or wet milled paste with water. In this study, fermented millet fl our supplemented with ginger powder blends were formulated in the ratio 100:0, 95:5, 90:10, 85:15, 80:20, 75:25 and 70:30 for the production of gruel. The blends were subjected to feeding trial experiment using wistar albino rat. Results analysis revealed that Serum cholesterol was less than 200 mg/dl. The fasting blood glucose was also within the recommended range (67.7 - 125.0 mg/dl). The biochemical parameters were within recommended range, total serum protein ranged from 5.82-7.06 g/L, Alanine aminotransferase ranged from 28.53 to 41.13 iu/L, Aspartate aminotransferase ranged from 28.50 to 48.66 iu/L. The albino rats showed slight increase in body weight throughout the experimental period, ranging from 78.67 -103.80 g. The experiment shows that the diet did not have any adverse effect on the experimental animals and were within the recommended range hence a good anti diabetic blend and has excellent biochemical profile properties for homes use.

Advanced technologies, such as electrochemical impedance spectroscopy (EIS), are a valuable tool which can enhance and simplify the industrial process monitoring if used correctly. State-of-the-art approaches for screening the cell growth of for example yeast during the brewing process still heavily rely on offline methods such as methylene blue or florescence dye-based staining, and/or the usage of flow cytometric measurements. These methods, while being accurate, are very time consuming and require heavy manual effort. Furthermore, the time span needed to obtain the counting result can lead to a time-delayed response signal and can impact the quality of the final product. In recent studies, applications of low-frequency EIS in the α-regime were used for the determination of cell counts and the metabolic state in Saccharomyces cerevisiae. This method has proven to be a reliable tool which has also shown high potential in industrial scale applications. The online biomass monitoring, as well as viable cell count, for feasibility study was performed in-house at Stiegl Brewery in Salzburg/Austria founded in 1492.

When Total Hip Arthroplasty (THA) is required in a patient with developmental dysplasia of the hip (DDH), bone deficiency in the acetabular roof often remains a problem. The iliac crest (IC) has long been the preferred source of autograft material, but graft harvest is associated with frequent complications and pain. Autologous bone graft can also be obtained from the femoral head (FH) for reconstruction of the acetabulum in hip arthroplasty. However, in certain challenging clinical scenarios, incorporation of the femoral head autograft appears less successful than the iliac crest autograft. The difference in potential for proliferation and osteoblastic differentiation between the two sites has still not been evaluated; therefore, it is not known how to compensate for this difference when it is present. We designed this study to evaluate the number of mesenchymal stem cells (MSCs) in both the iliac crest and femoral head of the same patient. We also determined the best operating room procedure for loading the femoral head with MSCs to achieve equivalent numbers of MSCs as in the IC. Twenty patients (8 men and 16 women) undergoing THA for DDH were enrolled in the study. The mean age was 55.5 years (range 41–65 years). Bone marrow aspirates were obtained from three depths within the femoral head and the aspirates were quantified relative to matched iliac crest aspirates that were obtained from the same patient at the same time. The cell count, progenitor cell concentration (cells/mL marrow), and progenitor cell prevalence (progenitor cells/million nucleated cells) were calculated. Aspirates of FH marrow demonstrated less concentrations of mononuclear cells compared with matched controls from the iliac crest. Progenitor cell concentrations were consistently lower in FH aspirates compared to matched controls from the iliac crest (p = 0.05). The concentration of osteogenic progenitor cells was, on average, 40% lower in the FH aspirates than in the paired iliac crest samples (p = 0.05). However, with bone marrow aspirated from the iliac crest, we were able to load the femoral head autograft with sufficient MSCs to obtain the same number as present in an iliac crest. With concentrated bone marrow from the IC, supercharging the femoral autograft with MSCs to numbers above that present in the IC was possible in the operating room, and the number of MSCs supercharged in the femoral head was predictable. Based on these findings we suggest that FH graft supercharged with BM-MSCs from the IC is comparable to IC graft for osseous graft supplementation especially in THA for patients with DDH.

Rhabdomyosarcoma is a soft tissue pediatric sarcoma composed of cells which show morphological, immunohistochemical and ultrastructural evidence of skeletal muscle differentiation. To date four major subtypes have been recognized: embryonal, alveolar, spindle cell/sclerosing and pleomorphic. All these subtypes are defined, at least in part, by the presence of rhabdomyoblasts, i.e. cells with variable shape, densely eosinophilic cytoplasm with occasional cytoplasmic cross-striations and eccentric round nuclei. It must be remembered, however, that several benign and malignant pediatric tumours other than rhabdomyosarcoma may exhibit rhabdomyoblaststic and skeletal muscle differentiation. This review focuses on the most common malignant pediatric neoplasm that may exhibit rhabdomyoblastic differentiation, with an emphasis on the most important clinicopathological and differential diagnostic considerations.

Infectious bursal disease (IBD) considered as one of the major viral diseases threatening the poultry industry worldwide. The causative agent of the IBD is Infectious bursal disease virus (IBDV) which replicates in developing B lymphocytes in the bursa of Fabricius leading to its destruction and bursal inflammation. In this study, we investigated a technology to produce therapeutic recombinant antibodies against IBDV in bacteria by constructing a bacterial displayed recombinant scFv library from immunized chickens, followed by screening the scFv library by fluorescence activated cell sorting (FACS) with FITC-labeled VP2. Twelve VP2-binding scFv clones with unique sequences were obtained, with overall amino acid homology of 81.53%. The complementarity determining region (CDR) 3 in the heavy chain displayed the lowest homology, while the amino acid sequences in framework regions and CDR2 of both chains and CDR1 of the heavy chain are relatively conserved. Twelve VP2-binding scFv clones were expressed in E.coli and purified through denaturation and denaturation of inclusion bodies. Our ELISA results showed that all scFvs exhibited binding ability and specificity to VP2 and various IBDV strains. In addition, two scFvs showed significant neutralizing activity to IBDV (B-87 strain) as these scFvs inhibited cytopathic effect of chicken embryo fibroblast (DF1) caused by IBDV. In conclusion, our study provides a lead candidate for further development of therapeutic antibodies for IBDV infection.

Introduction: Congestive heart failure is one of the main causes of morbidity and mortality in the XXI century given the promising to date of ABMDSCs and HFDSCs we investigate the safety and efficacy for the implantation of those stem cells for the treatment of idiopathic cardiomyopathy. This is the first pilot clinical study to assess the safety and feasibility of HFDSC in humans. We totally implanted 13 patients: 3 patients were implanted with ABMDSC by Mini-invasive surgical technique in March 2004 in Montevideo, Uruguay, and 10 patients were implanted with HFDSCs by using 2 different surgical techniques: minimally invasive technique (1 patient) and full sternotomy technique (9 patients) between January and February of 2005 in Guayaquil Ecuador. The HFDSCs were obtained from fetuses of 5 to 12 weeks´ gestation from legally consent, no compensated donors who have undergone terminated ectopic pregnancies, elective abortions, or spontaneous miscarriages. At that gestation´s period, totipotent stem cells´ fetus haven´t develop yet the HLA histocompatibility complex, so there´s no possible antigenicity between donor and recipient. Results: Patients with HFDSCs improved in association with increased contractility in these regions. Compared with baseline assessments, we noted other improvements: The mean (±SD) NYHA class decreased from 3.4±0.5 to 1.33±0.5 (P=.001); the mean EF increased 31%, from 26.6% ± 4.0% to 34.8%±7.2% (P=.005); performance in the ETT increased 291.3%, from 4.25 minutes to 16.63 minutes (128.9% in metabolic equivalents, 2.45 to 5.63) (P<.0001); the mean LVEDD decreased 15%, from 6.85±0.6cm to 5.80±0.58cm (P<.001); mean performance in the 6-minute walk test increased 43.2%, from 251±113.1 seconds to 360±0 seconds (P=.01); the mean distance increased 64.4%, from 284.4±144.9m to 468.2±89.8m (P=.004); and the mean result in the Minnesota congestive HF test decreased from 71±27.3 to 6±5.9 (P<.001) The Kaplan-Maier probability of survival at 48 months was 66%. It is not observed rejection, these patients have not developed malignance nodules or cancer at all in the follow-up. In the AMBCSs. The preoperative average NYHA functional class was 3.4; at. 6 months of follow up the average functional class value was 1.3 (p<0,005);. After 6 months all of them remained in functional class I/II. Baseline values of LVEF were 25,28 and 30%.; at 6 months increased to 38, 40 and 46%. (p<0,05). LVESV went from 50mm to 42mm (p<0.05). After 24 months, 2 of the patients still maintained this improvement, while the 3er patient returned to the earlier values after suffering from pneumonia. At 12 years and 5 months 2 patients are alive both received a Resynchronization Therapy; at 8 years and 3 months and 9 years and 1,6 month the actual average EF are 28 and 30 %. The 3er patient died of sudden death at 10 years after the implantation. We can´t demonstrate the cause of this sudden death. Conclusion: Irrespective of the improvement seen in this study, it is still premature to determine accurately the mechanism of action, indications, doses and type of stem cells. Therefore, is imperative and extremely important that more research is needed.

Varied exogenous chondrogenic factors (CFs) are implicated in promoting differentiation of stem cells along a chondrocyte lineage in the field of regenerative tissue engineering for articular cartilage repair. The effects of dexamethasone, transforming growth factor β3 (TGF-β3), ascorbate, and their combinations, on mRNA expression in micromass-cultured human adipose derived stem cells (hADSCs) were investigated as a function of time. Indices include chondrogenic, hypertrophic, angiogenic, fibrogenic and osteogenic markers along with mechanical properties, assessed by atomic force microscopy. Early in the culture, i.e., at day three, no significant differences in mRNA expression of SOX9, aggrecan, lubricin, Col XI, Col X, vascular endothelial growth factor, Col I, and alkaline phosphatase were observed among samples treated with different CFs. However, significant differences in mRNA expression levels of pre-mentioned markers among samples treated with each CF exist when samples were supplied with the CFs for more than three days. A new indexing scheme summing expression of chondrogenic and subtracting non-chondrogenic angiogenic, fibrogenic and osteogenic marker levels shows dexamethasone is the overall leading CF among the factors and their combinations. Based on this scheme, we have projected not only the possible signaling pathways which might be affected by addition of CFs but also hypothetical indexes that may occur upon temporal variation of growth factor regimens.

Research into regulation of the differentiation of stem cells is critical to understanding early developmental decisions and later development growth. The transcription factor ARID3A previously was shown to be critical for trophectoderm and hematopoetic development. Expression of ARID3A increases during embryonic differentiation, but the underlying reason remained unclear. Here we show that Arid3a null embryonic stem (ES) cells maintain an undifferentiated gene expression pattern and form teratomas in immune-compromised mice. However, Arid3a null ES cells differentiated in vitro into embryoid bodies (EBs) significantly faster than control ES cells, and the majority forming large cystic embryoid EBs. Analysis of gene expression during this transition indicated that Arid3a nulls differentiated spontaneously into mesoderm and neuroectoderm lineages. While young ARID3A-deficient mice showed no gross tissue morphology, proliferative and structural abnormalities were observed in the kidneys of older null mice. Together these data suggest that ARID3A is not only required hematopoiesis, but is critical for early mesoderm differentiation.

Age related macular degeneration is a severe disease of mainly elderly people and leads to central vision loss because of the degeneration of the retinal pigment epithelium [1]. Genetic and environmental factors are responsible for the accumulation of extracellular material and deposit formation near the retinal pigment epithelial (RPE) layer, which leads to loss of photoreceptors and induction of chronic inflammation. The deposits are composed of lipids and proteins including many complement proteins, indicating the involvement of the complement system in the degenerative process and chronic inflammation [2]. So far there is no treatment for the dry form of AMD, except nutritional supplementation with antioxidants and vitamins [3]. Combined with a prolonged lifetime expectation in developed countries, AMD is developing to a social and economic burden. Therefore, there is an urgent need for a treatment of AMD that can delay disease manifestation and progression for several years. 

In the current study, combinatorial therapeutic approaches to DNA/RNA of human cancer cells and Benzylpenicillin (Penicillin G), Fluoxetine Hydrochloride (Prozac and Sarafem), Propofol (Diprivan), Acetylsalicylic Acid (ASA) (Aspirin), Naproxen Sodium (Aleve and Naprosyn) and Dextromethamphetamine nanocapsules with surface conjugated DNA/RNA of human cancer cells to targeted Nano drugs for enhanced anti-cancer efficacy and targeted cancer therapy using Nano drugs delivery systems were investigated.

Red blood cell (RBC) alloimmunization can be a life-threatening complication for patients with thalassemia major and sickle cell disease (SCD) who must receive chronic therapeutic transfusions. Chronic transfusions can lead to erythrocyte alloimmunization, patients continue to develop alloantibodies due to the transference of the immunogenic antigens on the donor RBCs. Many complications are possible. Difficulty in finding compatible match units for the patients can cause transfusion delays delayed, or present alternative risks to the patients from delayed hemolytic transfusion reactions. This review discusses the possible mechanisms, risk factors associated with alloimmunization formation and the hemolytic transfusion reactions and also describe the guideline for transfusion management of these patients, including opportunities and emerging approaches for minimizing this life-threatening complication.

Amyloid-β peptide (Aβ) and tau protein deposits in the human brain are the pathological hallmarks of Alzheimer’s disease (AD). Tau is a class of proteins that are abundant in nerve cells and perform the function of stabilizing microtubules. However, in certain pathological situations, Tau proteins become defective and fail to adequately stabilize microtubules, which can result in the generation of abnormal masses that are toxic to neurons. This process occurs in a number of neurological disorders collectively known as Tauopathies. Tau protein is the major factor of the intracellular filamentous deposits that relate to a number of neurodegenerative diseases which includes the progressive supranuclear palsy (PSP), Pick’s disease, and Parkinsonism. The identification of mutations in Tau established that dysfunction or misregulation of tau protein is sufficient to cause dementia and neurodegeneration. In this review article, we discussed the etiology of the tau formation and role in AD and subsequently therapeutic approach for disassembling and Tau inhibition.

Regenerative medicine is a modern approach of dermatological treatment, using Epidermal Cells of the interfollicular epidermis (ESCs) for their effect in skin regeneration in chronic ulcers and burns, melanoma, vitiligo, junctional epidermolysis bullosa. Intraepidermal injections of autologous epidermal cell suspension can be a new and very promising treatment for many other cutaneous disorders as non-scarring alopecia (Alopecia Areata, Androgenic Alopecia) or scarring alopecia (Lichern Plano Pilaris alopecia, Discoid Lupus Erithematosus alopecia), anti-aging therapies. The intraepidermal injection of an autologous epidermal cell suspension is a simple, fast and safe surgical procedure: a small, thin portion of the epidermis of the patient undergoes a treatment where a suspension with all the cells collected from the epidermis and cultured for 7 days is injected into the skin. Our preliminary study shows that a suspension contains a significant number of viable cells that survive at day 7 in culture. Our research is ongoing and is focusing on the typing of the different cells in the suspension and evaluation of the presence and the nature of stem cells.

Mesenchymal stem cells (MSCs) are multipotent adult stem cells that can self-renew and differentiate into a variety of cell types including chondrocytes, osteocytes and adipocytes. MSCs reside in bone marrow, adipose tissues, cord blood, peripheral blood, placenta, Wharton’s jelly, fetal liver and lung among others. MSCs represent one of the most promising stem cells for regenerative medicine due to their multipotency, immunoprivileged properties and easy expansion in vitro. So far, MSCs are already in various phases of clinical application [1-4].

Heavy metals and metalloids are dangerous because they have the tendency to bioaccumulate in biological organisms over a period of time. However, it is conceived that a number of phytochemical agents as well microorganism can act as heavy metal removing agent both from human beings and the environment surrounding. For instance, microbes are used for the removal of heavy metals from the water bodies including bacteria, fungi, algae and yeast. This review shows that bacteria can play an important role in understanding the uptake and potential removal behaviour of heavy metal ions. The bacteria are chosen based on their resistance to heavy metals (incl. their toxicities) and capacity of adsorbing them. Due to specific resistance transfer factors, cell impermeability is drastically inhibited by several ion (i.e. mercury, cadmium, cobalt, copper, arsenic) forms. Between these elements, free-ion cadmium and copper concentrations in the biological medium provide more accurate determination of metal concentrations that affect the bacteria, than with most of the other existing media. Metal toxicity is usually assessed by using appropriate metal ion chelators and adjusting pH factor. Bacteria and metals in the ecosystem can form synergistic or antagonistic relationships, supplying each other with nutrients or energy sources, or producing toxins to reduce growth and competition for limiting nutritional elements. Thus, this relation may present a more sustainable approach for the restoration of contaminated sources.
