Clinico-radiographic Studies on The Prevalent Distal Limb Affections in Working Equine at Luxor City

To illustrate the clinical and radiographic findings of some distal limbs affections in Ninety two animals (24 horses and 68 donkeys) which were admitted to Animal Care Hospital in Luxor. Each animal was subjected to thorough clinical and radiographic examination; the grade of lameness was recorded and the best radiographic views were taken.  Fifteen types of distal limb affections were evident. The most prevalent affections in donkeys were high and low ring bone (29.35%) and hoof abscess ( 9.78%) followed by traumatic arthritis of the fetlock (6.52%), suspensory ligament desmitis (5.43%), fracture of first phalanx (5.43%), fracture of PII (4.35%), side bone (3.26%)  whereas, fracture of metacarpal bone (1.09%), sesamoditis (1.09%) and flexural deformities (1.09%)  represented the lowest prevalent affections.On the other hand, side bone (4.35%), fracture of the metacarpal bone (4.35%) represented the most prevalent affections in horses followed by high and low ring bone (3.26%), fractures of PI (2.17%), PII (2.17%), subluxation of coronopedal joint (2.17%) and punctured wounds in of the hoof (2.17%), traumatic arthritis of the fetlock joint (2.17%). Whereas, navicular disease (1.09%), suspensory ligament desmitis (1.09%) and hoof abscess (1.09%) were the lowest prevalent affections in horses. Treatment was not recommended in certain cases. In conclusion, although the wide stride progress have made in diagnostic imaging in recent decades, the x ray still offers a satisfactory tool for diagnostic imaging in equine limb practice that is useful for equine practitioners

Effect of Counteracting Lifestyle Barriers through Health Education in Egyptian Type 2 Diabetic Patients

BACKGROUND: Egypt is among the world top 10 countries in diabetes prevalence. It is the first country among the MENA region. Healthy lifestyle education and support help people with diabetes to improve health outcomes. Many physical and psychological barriers can hinder patients from following a healthy lifestyle. AIM: This study aimed to examine the effect of lifestyle modification educational sessions in helping Egyptian patients to overcome main barriers of diabetes self-management through improving nutritional behaviours, physical activity, medication compliance, and blood glucose monitoring. METHODS: A cohort study included 205 patients with type 2 diabetes. Baseline assessment of patients' lifestyle behaviours and barriers using personal diabetes questionnaire of Louisville University, with both anthropometric and blood glucose assessment. Interventional lifestyle health education was provided weekly through multiple integrated techniques, followed by a post-intervention assessment to evaluate the effect of the health education sessions. Statistical analysis was done to identify any statistically significant difference before and after the health education intervention. RESULTS: There was a significant improvement of the post-education mean scores of the studied behaviours when compared with the pre-education scores of the participants’ behaviours (p < 0.001). There was also a significant reduction in the barriers facing patients to diabetes self-management including nutritional barriers (P < 0.001), medication compliance barriers (P < 0.001) with a percent change (43%), physical activity barriers (p < 0.001), and blood glucose monitoring (p < 0.001) with a percent change (44%).There was a statistically significant positive correlation between improvement of medication compliance (P = 0.027), blood glucose monitoring(P = 0.045), and glycated haemoglobin of the study participants CONCLUSION: lifestyle modification education of type 2 diabetic patients can overcome the main barriers of following a healthy lifestyle and improve their anthropometric measures and blood glucose level

Ameliorative effect of biosynthesized titanium dioxide nanoparticles using garlic extract on the body weight and developmental toxicity of liver in albino rats compared with chemically synthesized nanoparticles

The application of metallic nanoparticles poses risks to human and animal health. Titanium dioxide nanoparticles (TiO2NPs) are the most commonly synthesized metallic oxides in the world. Exposure to TiO2NPs can cause toxicity in the target organisms. This study aimed to evaluate the effects of green and chemical TiO2NPs on maternal and embryo-fetal livers. Green TiO2NPs using garlic extract (GTiO2NPs) and chemical TiO2NPs (CHTiO2NPs) were synthesized and characterized by x-ray powder diffraction and high-resolution transmission electron microscopy. The cytotoxicity of both chemical and green TiO2NPs was determined against HepG2 cell lines. Fifty pregnant female Albino rats were equally and randomly divided into five groups. Group 1 was kept as a control. Groups 2 and 3 were orally treated with 100 and 300 mg/kg body weight of CHTiO2NPs, respectively. Groups 4 and 5 were orally treated with 100 and 300 mg/kg of GTiO2NPs, respectively, from day 6 to 19 of gestation. All dams were euthanized on gestation day 20. All live fetuses were weighed and euthanized. Blood and tissue samples were collected for biochemical, histopathological, and Bax-immunohistochemical expression analyses. Our results indicated that garlic could be used as a reducing agent for the synthesis of TiO2NPs, and the produced NPs have no toxic effect against HepG2 cells compared with CHTiO2NPs. The maternal and fetal bodyweights were greatly reduced among the chemically TiO2NPs induced animals. The mean serum level of AST and ALT activities and the total protein level significantly increased when TiO2NPs were administered at high doses. Histologically, the CHTiO2NPs-treated groups revealed vacuolated and necrotized hepatocytes with congested and dilated blood vessels in the fetal and maternal livers. The immunohistochemistry revealed distinct positive staining of Bax expressed in the hepatocytes. Nevertheless, the biosynthesis of TiO2NPs using garlic extract had a minimal effect on the normal architecture of the liver. It could be concluded that the bioactivity of TiO2NPs can be modified by green synthesis using garlic extract. Compared to the CHTiO2NPs, the exposure to GTiO2NPs showed reduced liver damage in maternal and embryo-fetal rats

In Vivo Investigation of the Ameliorating Effect of Copper Albumin Complex on chondroitin sulfate in Monosodium iodoacetate -Induced Knee Osteoarthritis

Osteoarthritis (OA) is a condition that manifests as cartilage deterioration and subchondral bone sclerosis in the joint tissues. The weight-bearing joint is most severely impacted by OA. According to some research, consuming foods high in copper albumin complex (cu-albumin complex) can help with OA-related joint degeneration and pain relief. The current study's objective to determine how oral administration of the cu-albumin complex as an anti-inflammatory medication affected the development of rat knee osteoarthritis (KOA). Fifty adult albino rats were divided into three groups: negative control untreated (n= 10, no KOA induction); positive untreated control (n= 20, KOA induction); and treated group (n= 20, KOA induction with administration of cu-albumin complex). According to the severity of the clinical symptoms, treated and untreated arthritic groups were equally divided into mild and severe groups (n=10). Monosodium iodoacetate (MIA) was used as intra-articular injection for osteoarthritis induction. Rats were euthanized after a month of the beginning of the experiment, and the joints were examined histopathologically and immunohistochemically. It was indicated that the treatment was effective in reducing KOA severity and in improvement of chondroitin sulfate of the affected cartilages. In conclusion, the structure of the chondroitin sulphate in the knee joint cartilages of KOA-affected rats was modified by the cu-albumin complex

Investigation of the Ameliorating Effect of Copper Albumin Complex on Lysyl oxidase in monosodium iodoacetate -Induced Knee Osteoarthritis in Rats

Knee osteoarthritis (KOA) is a common type of joint degeneration which causes progressive damage of the joint structure and has less therapeutic options. It has been found that oral consumption of Copper Albumin Complex as anti-inflammatory drug has a positive effect on the treatment of joint deterioration. The present study aimed to investigate the effect of oral administration of Copper Albumin Complex (cu-albumin complex) on Lysyl oxidase (LOX) which acts as a protective factor in KOA. Fifty adult albino rats were divided into 3 groups: negative control (10 normal rats); positive control (20 rats with KOA which left without induction treatment); and treated group (20 rats with KOA which treated with administration of copper albumin complex). Treated and untreated arthritic groups were subdivided equally into mild and severe groups (10 rats for each) according to the severity of clinical signs. KOA was induced by intra-articular injection of monosodium iodoacetate (MIA). At the experimental end, the joints were examined histopathologically and immunohistochemically after cervical dislocation of rats. It was observed that the treatment with CU- was effective in reducing disease severity and in improvement of Lysyl oxidase KOA. It was concluded that Copper albumin complex has a positive effect in the improvement of LOX of Knee joint cartilages of rats affected by osteoarthritis (OA)

Mistranslation Drives Alterations in Protein Levels and the Effects of a Synonymous Variant at the Fibroblast Growth Factor 21 Locus

Fibroblast growth factor 21 (FGF21) is a liver-derived hormone with pleiotropic beneficial effects on metabolism. Paradoxically, FGF21 levels are elevated in metabolic diseases. Interventions that restore metabolic homeostasis reduce FGF21. Whether abnormalities in FGF21 secretion or resistance in peripheral tissues is the initiating factor in altering FGF21 levels and function in humans is unknown. A genetic approach is used to help resolve this paradox. The authors demonstrate that the primary event in dysmetabolic phenotypes is the elevation of FGF21 secretion. The latter is regulated by translational reprogramming in a genotype- and context-dependent manner. To relate the findings to tissues outcomes, the minor (A) allele of rs838133 is shown to be associated with increased hepatic inflammation in patients with metabolic associated fatty liver disease. The results here highlight a dominant role for translation of the FGF21 protein to explain variations in blood levels that is at least partially inherited. These results provide a framework for translational reprogramming of FGF21 to treat metabolic diseases.Peer reviewe

Down-regulation of circulating microRNA let-7a in Egyptian smokers

Altered miRNAs were associated with cigarette smoking. The study aimed to examine the gene expression level of plasma let-7a among healthy smokers and compared it with the non-smokers. Forty subjects were recruited for the present study and classified into 21 smokers and 19 non-smokers, age, and sex were matched. The software that used to design functional primers was MIRprimer. Quantitative real-time PCR was employed to compare the relative expression of plasma let-7a. Results showed that the level of let-7a was down-regulated in smokers to 0.34fold (p = 0.006) that of the non-smokers. Plasma let-7a showed an area under curve (AUC) of 0.749 with sensitivity 43% and specificity 100%. In conclusion, plasma let-7a was significantly down-regulated in the smokers, and it might be considered a candidate biomarker to discriminate between smokers and non-smokers.

Strengthening vaccines and medicines manufacturing capabilities in Africa: challenges and perspectives

Africa carries a high burden of infectious diseases. Every year, millions of Africans contract tuberculosis, malaria, and many other diseases. Malaria kills hundreds of thousands of children under the age of five years annually. More than 11,000 people died during the 2014–2016 Ebola outbreak in West Africa; still, occasional cases of Ebola, as well as monkeypox, periodically appear in the Democratic Republic of Congo. Since most of the African countries gained their independence during the 1960s, the continent has relied heavily on the outside world for diagnostics, medicines, vaccines, personal protective equipment, and other medical supplies. Africa consumes nearly 25% of the globally produced vaccines but imports 99% and 95% of its vaccines and medicines, respectively. The 55 African countries were not able to ensure the health of 1.3 billion Africans during the COVID‐19 pandemic but had to rely on other global initiatives and other countries for help and support. However, the pandemic and the shortage of vaccines may have been the much‐needed trigger for this situation to change. “When misfortunes increase, they erase each other.” Naguib Mahfouz (1911–2006)

Disease History, Pathogenesis, Diagnostics, and Therapeutics for Human Monkeypox Disease: A Comprehensive Review

The monkeypox disease is a zoonotic-infectious disease that transmits between animals and humans. It is caused by a double-stranded DNA virus belonging to the Orthopoxvirus genus that is closely related to the variola virus –the causative agent of smallpox. Although monkeypox infections were endemic to Western and Central Africa, the newly emerging monkeypox outbreak spread to more than 90 non-African countries. With the exception of the PCR-confirmed case of a return from Nigeria to the United Kingdom, the ongoing outbreak is largely unrelated to travel. In the most recent wave, cases are characteristically males in their thirties. Risk factors include close and particularly sexual contact with an infected person, and contact with fomites, infected animals or aerosolized-infectious material. Clinical diagnosis of monkeypox is confirmed with nucleic-acid amplification testing of samples originating from vesicles or genital lesions and using real-time or conventional PCR. Other methods, such as electron microscopy, immunohistochemistry, and virus culture are costly and time-consuming. In addition to timely diagnosis and contact tracing, restrictive measures to limit spread, such as isolation of infected patients, preventing contact with wild animals, and isolation of animals suspected to be viral reservoirs have shown promise. Although there are no specific treatments for monkeypox disease, the experience with smallpox suggests that the vaccinia vaccine, cidofovir, tecovirimat, and vaccinia immune globulin (IVG) may be beneficial for monkeypox treatment. In this review, we provide an update on the human-monkeypox disease with a special emphasis on its pathogenesis, prevention, diagnostics, and therapeutic measures
