Pollinators are very critical when it comes to the reproductive success of plants. They promote outbreeding which holds immense significance in the era of global climate change. It allows the plants to become fertilized, to produce seeds, fruits, and eventually new plants. They are instrumental in the sustainability of our ecosystem. Thus, there is an essential need to study these pollinators to understand how, during the course of evolution, they have co-evolved with the flowering plants to shape floral architecture and community dynamics thriving in the vicinity. In this mini-view, we shall focus our discussion on some of the animal pollinators, the dwindling diversity of animal pollinators, and various associated pollination syndromes.

Sawdust is a by-product or waste product of woodworking such as cutting, sanding, machining, planning, and routing. Saw dust consists of small woodcutting intending to study the structural morphology of organic waste fiber derived in an X-band frequency and synthesis of the rice dust and sawdust. The solid-state method was employed to mix the husk, to obtain the fine power, and the Fourier-transform infrared spectroscope was used to determine the sample absorption rate. The FTIR results show that the best samples are 6.5 g and 6.5 g rice bark and sawdust, with an absorbance rate of 86% and 14% transmission, which will be used for the manufacture of electronic and communication devices.

Background: Polycystic ovary disease (PCOD) is an endocrine disorder. It leads to menstrual disturbances, infertility, obesity and dermatological manifestations such as hirsutism and acne which leads to impaired health-related quality of life (QOL). Aims: To evaluate the perceived health related QOL in patients with PCOD treated with ethinyl oestradiol (35µg)/cyproterone acetate (2 mg) (EE/CPA) and ethinyl oestradiol (20 µg)/ desogestrel (0.15mg) (EE/DES) alone and in combination with low-dose metformin. Methods: A total of 117 patients with PCOD diagnosed according to Rotterdam Consensus Criteria 2003 with a hirsutism score of 8 or more according to modified Ferriman-Gallway Score (mFGS) were randomised to receive one of four drug combinations (arm A – EE/CPA, arm B- EE/DES, arm C- EE/CPA plus metformin, arm D- EE/DES plus metformin). The outcomes assessed were body mass index (BMI), hirsutism (using mFGS) and health-related QOL (Polycystic Ovary Syndrome Health- Related quality of life Questionnaire (PCOSQ) and a Visual Analog Scale (VAS) score) at baseline and 12 months after treatment. Results: PCOSQ score in relation to the hirsutism, emotions, menstruation, obesity, infertility and VAS score in relation to hirsutism and obesity had improved at the end of 12 months (p< 0.001) in all treatment arms. There was no difference between treatment arms in all measured outcomes at baseline and at the end of 12 months. Conclusion: Treatment with EE/CPA and EE/DES is associated with an improvement in perceived QOL in patients with PCOD. The addition of low-dose metformin did not have a significant benefit.

Background: Minigastric bypass is gaining popularity worldwide as an effective bariatric surgery which has fewer complications than RYGB. There is raising concerns about biliary reflux and its effect on gastric mucosa. In this study we tried to find the link between the presence of bile in the stomach and the incidence of gastritis after MGB. Methods: This prospective study was conducted in Ain Shams university hospitals from January 2017 to May 2018 including 40 patients. All patients underwent MGB with a 12-month follow-up, UGI endoscopy was performed 9 months after MGB for all patients, where multiple biopsies and gastric aspirate were obtained for bilirubin level Results: Mean age at operation was 32 years (18–60) and preoperative BMI 44.31 kg/m2. The mean operative time was 95 (± 18 min), Mean % EWL was 81.2% at 12 months. Complete resolution occurred of hypertension in 8 patients (80%) and of Diabetes type 2 in 11 patients (84.2%). Level of bilirubin in gastric aspirate was elevated in 8 patients (20%) all of them had different levels pouch gastritis confirmed by histopathological examination. Conclusion: Biliary reflux reached about 20% after MGB, the severity of biliary gastritis is related to the elevation of bilirubin level in the gastric aspirates, this results need to be confirmed by further studies on the MGB.

Introduction: Abdominal hernia is a pathological condition resulting from abnormal protrusion of abdominal viscera. In particular, internal hernias (IH) represents about 0.2-0.9% of all cases with para- duodenal hernias while obturator hernias accounting for only 0.07% of all hernias. Methods: We reported the case report of 79 year old women who was admitted to Internal Medicine Department of our Hospital for lung failure and after few days transferred to our Surgery Department for abdominal pain. Conclusion: Obturator hernia is rare type of hernia and it is more frequent in older women with history of multiple pregnancy, chronic cough, and habitual constipation. In our patients, detailed physical examination and MRI preoperative imaging studies, have induce to the successful diagnosis.

The rehabilitation of partially or completely edentulous patients with implant supported prostheses has been widely used, achieving high success rates. However, many studies consider the presence of bruxism as a contraindication for this treatment modality. The purpose of this study was to review the literature and identify risk factors in implant supported rehabilitation planning in subjects with bruxism. The rehabilitation of bruxers using implant supported prostheses, using implants with adequate length and diameter, as well as proper positioning, seems to be a reliable treatment with reduced risks of failure. Bruxism control through the use of a night guard by rigid occlusal stabilization appliance, relieved in the region of implants, is highly indicated. Although it is clear that implant supported rehabilitation of patients with bruxism requires adequate planning and follow-up, well-designed randomized controlled trials are needed to provide reliable evidence on the long-term success of this treatment modality.

There is evidence that complement components induce cell migration in mesenchymal stem cells and regulate cytokine production in osteoblastic cells thus playing a regulatory role in normal bone formation. The aim of the present study was to investigate the involvement of complement system in the differentiation of bone marrow cells in complement-depleted model of rheumatoid arthritis (RA). Arthritis was induced by intraarticular injection of zymosan in cobra venom factor (CVF)-treated mice depleted of functional complement. The expression of different markers by bone marrow [1], on fibroblasts (CD29), mesenchymal cells (CD105), dendritic cells (CD14, CD86), osteoclasts (CD265), cells expressing Dectin1 (CD369) and megakaryocytes (CD62P) was determined by flowcytometry. The lack of functional complement activity at the point of arthritis initiation (day 3) lead to an increase of fibroblast and megakaryocyte populations, to a decrease of mature and dectin1 positive populations, while the number of mesenchymal cells was not changed, all compared to arthritic mice. Immunohistochemical staining showed that low complement activity diminished arthritis-induced generation of megakaryocytes and platelets in BM. Chronic inflammation during erosive conditions such as rheumatoid arthritis, leads to dysregulated differentiation and prolifеration of bone cells, inflammation of synovial membrane and bone marrow, and degradation of cartilage and bone. Present results point that the lack of functional complement changed the ratio between different cell populations that can be used for determining the development and stage of rheumatoid arthritis and can help finding of new therapeutic approaches.

As healthcare systems develop, there is an explicit call towards interprofessional learning and working, valuing observations and perspectives of all disciplines. Such a multi-perspective is pivotal for innovation, leading to optimal and sustainable health care. In such an interprofessional work environment, it is obvious that the nurses engage in the formulation of research questions within clinical practice settings. This case report describes a case in which nurses observed important issues that no physician or midwife on the team would have noticed. In collaboration with other team members, the nurses subsequently engaged in research which resulted in new information to improve care. The aim of this paper is to explore strategies to promote nurse participation in at least the formulation of research questions based on their observation and perspectives.For fostering critical nurse observation as a source of research topics, we propose four strategies. First, cultivating awareness through a culture of evidence-based practice and critical reflection on common practice. Second, stimulating persistence in addressing moral dilemmas concerning better care despite resistance. Third, facilitating interprofessional learning in an open culture, where diverse perspectives are valued, and it is psychologically safe to bring them in. Fourth, overcoming funding disparities and facilitating nurse-led research, acknowledging the underrepresentation of nurses in funding agencies. These measures aim to empower nurses to observe critically, use their unique perspectives, and bring in research topics.

Correcting class II malocclusion has always challenged an orthodontist owing to the complex and multifactorial aetiology. Age of patient and selection of the appliance plays an important role in the outcome of the treatment. Growth modification using functional appliances achieves stable results in class II patients. An orthodontist has wide variety of fixed and removable appliances for addressing a class II malocclusion. In this review article an attempt has been made to compile various available fixed functional appliances. 

Mesenchymal stem cells are heterogenous adult multipotent stromal cells that can be isolated from various sources including bone marrow, peripheral blood, umbilical cord blood, dental pulp, and adipose tissue. They have certain regenerative, anti-inflammatory, immunomodulatory, immunosuppressive, antimicrobial, and other properties that enable them to have several therapeutic and clinical applications including treatment of various autoimmune disorders; role in hematopoietic stem cell transplantation and regenerative medicine; treatment of skin, pulmonary and cardiovascular disorders; treatment of neurological and eye diseases; as well as treatment of various infections and their complications. Different factors including donor age, biological source, route of administration, and signaling pathways have an impact on the functions and consequently the clinical applications of mesenchymal stromal cells. The products of mesenchymal stem cells such as extracellular vesicles and exosomes reproduce the biological effects and most of the therapeutic actions of the parent stem cells. Genetic engineering and the use of specific mesenchymal stromal cell products have improved their clinical efficacy and decreased their adverse effects. However, despite the recent progress in the use of mesenchymal stem cells, the clinical application of these cells in the treatment of several diseases still faces real challenges that need to be resolved. The current status of mesenchymal stem cells and the controversies related to their clinical utilization in various disease conditions will be thoroughly discussed in this review.
