Evaluation of vitamin C as an adjunct to periodontal therapy
Authors: Katariya Chanchal , Jayakumar N. D.
Published: August 2022

Background: Periodontitis is an inflammatory disease that affects the periodontium, which is the protective apparatus that surrounds a tooth and includes the gingiva, alveolar bone, cementum, and periodontal ligament and is initiated by bacterial infection, subsequently progresses because of altered host response, and causes periodontal tissue destruction. These bacteria have the capacity to destroy the collagen fibres and ground substance directly by releasing virulence factors like enzymes - collagenase and toxins - gingipains. Indirectly act on various receptors like toll receptors and activate host immune response. Some immune cells like neutrophils, start producing reactive oxygen species (ROS). Vitamin C acts as an antioxidant, by acting as an electron donor Thereby preventing lipid peroxidation by ROS. Vit. C also controls collagen synthesis by directly activating collagen synthesis transcription and stabilizing procollagen mRNA. Along with other properties, Vitamin C is said to have anti-inflammatory and wound healing properties. Aim: This study aimed to systematically review to assess the effect of Vitamin C, as an adjunct to periodontal therapy.

Introduction: Several studies have demonstrated the superiority of Laparoscopic appendicectomy in managing acute appendicitis. Acute appendicitis has been managed solely by open appendicectomy at the University Teaching Hospital (UTH). This was the first study that looked at the management of acute appendicitis by laparoscopy at UTH. This study aimed to determine the outcomes of laparoscopic appendicectomy at UTH. Materials and Methods: This was a prospective cohort study that included patients that were diagnosed with acute uncomplicated appendicitis. All patients admitted between August 2015 to March 2016 were included in the study. Variables analyses were patient’s data (age, gender, previous surgery, WBC count, symptoms, signs, symptoms), operating time, intra\post operative complications, and length of stay. Results: A total of 9 laparoscopic appendicectomies were performed during the study period. The patients had an average age of 31.8 years and were predominantly female (70%). One case was converted to open appendicectomy and was not included in the laparoscopic data group. The mean operative time for the procedure was 75.5 min (range 50-110min). The length of stay was on average 2.3 days (range 2-3 days). The patients in the study had no complications noted during the follow-up period. No patient developed an intraabdominal abscess during the study period. Conclusion: Laparoscopic appendicectomy for uncomplicated acute appendicitis resulted in good surgical outcomes in this institution compared to the regional statistics as a reference point. It may be preferred in patients presenting with uncomplicated appendicitis or where the diagnosis is equivocal. Laparoscopic appendicectomy is recommended, especially for the young female patients in our setting.

Modulation of the gut microbiota with probiotics, living microorganisms with immunomodulatory effects, or prebiotics, nondigestible food ingredients that promote the growth and/or activity of beneficial microorganisms or a combination of both (synbiotics) may enable a new way of prevention or treatment for allergic disease. The aim of our study was to evaluate the ROS release from the peripheral blood neutrophils in patients with type I hypersensitivity reactions. To this end, we evaluated the basophil degranulation in the presence of specific allergens and analysed the influence of a synbiotic on neutrophil reactive oxygen species (ROS) generation. The tested synbiotic, directly or in combination with E. coli, decreased the ROS production in peripheral blood neutrophils of allergic patients. Taking into account that intensive ROS release is responsible for various damages of cells and tissues, the decrease of the oxidative stress induced by the tested synbiotic may have an essential role for cell protection and viability. Therefore, therapeutic interventions that enhance endogenous antioxidant defenses might be beneficial as adjunctive therapies for allergic disorders.

"Background. Lindane is an organochlorine pesticide considered as Persistent Organic Pollutant with immunosuppressive effects in acute exposure, but data on chronic exposure to low doses are still inconclusive. Aim. The aim of the study was to investigate immune and redox changes in mice chronically exposed to low doses of lindane. Experimental setting. Mice were chronically exposed for 6 months to lindane (5 mg/L) in drinking water, and subsequently a subgroup was challenged orally with S. typhimurium. The inflammatory factors MMP-9, IL-6 and KC, along with the antioxidant GSH were assessed in lungs, livers and kidneys. Splenocytes were stimulated ex vivo with TLR2 or TLR4 agonists, and the levels of released IL-6, IFNγ, TNFα and KC were measured in cell supernatants. Results. A decrease of IL-6 and MMP-9 lung levels and decreased IL-6 production by LPS-activated splenocytes from lindane-exposed mice were evidenced as compared to control groups. A slight increase of MMP-9, IL-6 and KC levels, and a decrease of GSH were observed in the liver of lindane exposed mice, while increased GSH levels were registered in infected lindane-exposed mice. Infection generally delivered stronger signals then lindane, but an immunomodulatory effect of lindane was shown in particular cases in splenocytes from infected lindane-exposed mice. Conclusion. Chronic exposure of mice to a low dose of lindane delivered in drinking water can induce both systemic immune suppression related to particular inflammatory factors, and inflammation, depending on the organ. Moreover, some immunomodulatory effects of lindane were highlighted in particular experimental settings."

Providential personalities have been writing history since the beginning of times – personalities that could be found within and across Romania’s borders [1]. In medicine, such brilliant figures have healed patients through diligence, dedication, and professionalism, but have also passed significant teachings to the next generations. They have rigorously respected an authentic professor’s definition, a figure that teaches and prepares specialists for the future. The great medical personalities, Ion Cantacuzino and Victor Babeș, have been mentored by famous professors, have also become famous professors on their own, and they have educated doctors and professors who have carried on their research and medical teaching legacies. Through study, through diligence, and an impressive personal development, their students have also become proficient figures in medicine [1-2]. They have trained personalities in the medical field that could have reached higher peaks, were it not for the political and social climate of their country. Among those, now we shall bring into discussion professor Matei Balș, a remarkable man and teacher, whose contribution focused the necessity of employing strict and correct means of practice, tying together in an organic way the clinical and the laboratory work, a dogma which he has passed on to his students. He has funded the “School of Infectious Diseases” at Colentina Hospital and has formulated teachings that stand the test of time; his working approach is still appropriate and praised today. The current generation as well as future ones not only have the obligation to recognise the exceptional achievements of our ancestors in history, but to also keep them alive and develop upon them, in the interest of the Romanian people, Romania itself, but also for the public health system at an international level [1].
Channel-Robust Specific Emitter Identification Based on Transformer
Authors: Huang Keju , Yang Junan , Liu Hui , Hu Pengjiang
Published: August 2022

Specific emitter identification (SEI) refers to the process of identifying emitter individuals based on corresponding wireless signals. Although deep learning has been successfully applied in SEI, the performance remains to be improved when the channel changes. In this paper, we suggest that a potential reason of the performance degradation is inadequacy of model capacity. Therefore, Transformer, an advanced neural network architecture with large model capacity, is applied for channel-robust SEI. Experimental results show that Transformer achieves better performance than conventional convolutional neural networks.

Published: August 2022

Pedestrian safety affects many fields such as driverless vehicles. In order to improve the precision of the pedestrian detection method and distinguish people-like objects from pedestrians, an improved YOLOv4 pedestrian detection method is proposed. Firstly, RepVGG Block is introduced into the feature extraction layer and feature fusion layer of YOLOv4 to improve the feature extraction ability of the network and reduce the loss of feature information. Then the SENet attention mechanism is introduced to make the algorithm focus more on the useful information. Finally, the SIoU loss function is introduced to the regression of the pedestrian target frame, which improves the convergence speed and reduces the blindness of the target frame. Experimental results show that, compared with the original YOLOv4 algorithm, this improved algorithm has higher detection precision, and it can also distinguish people from people-like objects on the published Pedestrian Detection Data set, with a detection precision of 83.7%.

Outcomes of Second-stage Reimplantation After Modular Knee Arthrodesis for Periprosthetic Joint Infection
Authors: Stavrakis Alexandra , Mayer Erik N. , Devana Sai , Chowdhry Madhav , Dipane Matthew , McPherson Edward
Published: August 2022

Background:

Modular knee arthrodesis (MKU) is a salvage treatment for recurrent periprosthetic joint infection (PJI) or PJI associated with notable bone loss. Reimplantation endoprosthetic reconstruction (REI) is an option in patients with MKU who have PJI clearance but are not satisfied with pain or functional outcomes with MKU. The purpose of this study was to evaluate the outcomes of MKU to REI conversion.

Methods:

This was a single-center retrospective cohort study of 56 patients who underwent MKU to REI from 2010 to 2019. All patients were staged according to the McPherson staging system. An infecting organism was documented based on pre-MKU aspiration or intraoperative cultures at the time of MKU. Rate ratios were calculated for relevant patient factors. Rate ratios were calculated using Poisson regression with a log link.

Results:

The mean REI patient age was 67 years, most of the patients were McPherson B hosts (62.5%) with a type 2 (46.4%) or type 3 (51.8%) limb score, and all PJI were chronic. The most common infecting organisms at the time of MKU were Staphylococcus epidermidis (23.2%) and Staphylococcus aureus (23.2%, MSSA 14.3%, MRSA 8.9%). The mean time from MKU to REI was 220 days. An 8.9% REI index hospitalization complication rate and a 21.4% overall complication rate (excluding reinfection) were observed. Sixty-seven percent of the patients remained infection-free at an average follow-up of 37 months, among those there was 96.4% implant survivorship. No notable association was observed between index PJI organism or McPherson staging and REI failure secondary to PJI.

Discussion:

Approximately two thirds of patients who undergo conversion from MKU to REI have infection-free survival at the midterm follow-up.

The precipitous expansion of ecotourism destinations and tourists has intensified competition in the tourism business. Thus, the present study investigates the connection between destination image and travel motivation that marketers must comprehend and focus on establishing ecotourism in Bangladesh. Despite a growing number of works on destination image, there has been little investigation on the relationship between travel motivation. This study aims to evaluate the effect of destination image and travel motivation on tourists’ selection of ecotourism destinations. Therefore, it utilised a structured survey aimed at visitors during their on-site experiences, unlike earlier studies that mainly focused on identifying destination characteristics. Using SPSS-SEM, the suggested structural model was evaluated using a sample of 326 tourists from various Bangladesh’s ecotourism destinations. The results confirmed that cognitive and affective destination images significantly influence travel motivation. It also indicates a better understanding of the relationship and significant managerial implications for destination marketing managers.

The Concept of Culture in F. R. Leavis’s Critical Writings
Authors: Al-Madari Dr.  Abdul Hamid Ahmed Nasser
Published: August 2022

Culture is an umbrella term under which come many things such as social behavior, knowledge, beliefs, habits, and customs. The concept of culture is one of the concepts that discussed and examined by different critics, among whom is F. R. Levis. The current research paper is aimed at analyzing the concept of culture in F. R. Leavis’s critical writings and his notes towards the definition of culture. This research paper opens a new window to the study of Leavis’s critical works. For Leavis, culture is only attainable by the educated elite. He stated that the cultured man is the one who is interested in literature and arts, and literature and arts represent what is good in the tradition of culture. Therefore, he opposed Marxism because it creates a literature that humiliates the human spirit. He also declared his dissatisfaction with the industrial society because of the emergence of the new cultural forms such as television, films, computer, and internet such as television, films, computer, and internet, which pose a threat to the living culture. That is to say, these new forms of culture are harmful because they have great impact on the local cultures. In brief, Leavis is narrow and dogmatic in his analysis of the concept of culture. He is supposed not to confine culture to the educated elite and to accept the new cultural forms because they have their actual existence that cannot be ignored.

TÌM HIỂU KHÁI NIỆM “NHÀ” TRONG NGHIÊN CỨU DI CƯ
Authors: Vy Trần Tịnh
Published: August 2022

Tuy là khái niệm cơ bản, nhưng “nhà” chứa đựng nhiều hàm nghĩa và liên tưởng tùy thuộc vào mỗi nền văn hóa và nhận thức. Vượt ra ngoài công thức nhận diện cơ bản về “nhà” như một nơi cư trú và gắn nhà với một thửa đất có thể định vị được, “nhà” trong trường hợp cộng đồng diaspora, bao gồm không chỉ một mà nhiều không gian và nơi chốn khác nhau, nơi chủ thể di cư liên tục nhận diện và hình thành căn tính. Bằng việc giới thiệu những cách hiểu cơ bản và phổ quát về “nhà”, bài viết phân tích khái niệm “nhà” trong nghiên cứu diaspora. Lí thuyết di cư đã cho thấy dưới tác động của quá trình di dân và sự va chạm của các nền văn hóa lẫn bản sắc, chủ thể di cư liên tục giằng co giữa việc họ xuất thân từ đâu và họ hiện đang ở đâu, dẫn đến việc họ tự hình thành nên các không gian “ở giữa”. Hơn thế nữa, chủ thể thậm chí có thể trải qua cảm giác mất quê hương ngay tại nơi mình sinh sống và bắt đầu hành trình tìm kiếm nơi bản thân họ thuộc về. Khái niệm “nhà”, do đó, trở nên phức tạp hơn nhiều so với cách tiếp cận cộng đồng diaspora truyền thống vốn dựa trên cảm thức hoài niệm, tình yêu quê hương và nguồn cội.
