The Bacterial Cytoskeleton based on Bacterial Translation Elongation Factor EF-Tu: Novel Insights

Bacteria possess an EF-Tu-based cytoskeleton.This article presents a short review. A number of questions which are not discussed in the former publications can be asked, such as: all bacteria possess a ribosomal protein synthesis system and, hence, also EF-Tu. EF-Tu is produced in an amount that is higher than the need for a function as translation elogation factor in ribsomal protein synthesis. This article tries to answer the question regarding the surplus of EF-Tu: formation of a "cell-wide web" by self-assembly as a feafure that stabilizes cell integrity. An additional question can be asked: what is the origin of this bacterial cytoskeleton? This article contains a speculation on this topic. A third question regards the'ntteructjon of ribosomes in the process of protemsynthesis: does the EF-Tu protein move to the ribosome, or does the ribosome move to the EF-Tu intergated in a fibril of the bacterial cytoskeleton? The former publication depicts electron micrographs which show colocalizatton of botth entities. EF-Tu is an example for aprotein with two independent functions: participation in the ribosomal protein synthesis as a kanslation elongation factor, and component of a bacterial cytoskeleton. This situation can open up a discussion ofthe sequence of events and states of early cells during evolution.

A young man presented with abdominal pain and vomiting after eating Naphthalene Mothball. He had dyspnea, central cyanosis (SaO2 on air was 67% on air), marked pallor, deep jaundice and dehydration. His urine color was black; and, his plasma in clotted blood sample was brownish. He was treated as methemoglobinemia due to suicidal Naphthalene Mothball poisoning with fluid and electrolyte replacement, ascorbic acid, N-acetylcystine and exchange transfusion twice with four units of whole blood. Dramatic improvement in central cyanosis immediately following exchange transfusion. Psychiatric consultation and counselling were done; he admitted the main reason for committing suicide was socioeconomic stress due to COVID-19.

A Girl from Qatar with Post-Infantile Acquired Cerebral Palsy Caused By Submersion Injury: A Rare Etiology and a Therapeutic-Challenge.

Background: Cerebral palsy is a heterogeneous disorder that can cause a lifelong disability that is associated with a non-progressive damage in the brain. It is commonly caused by antenatal, perinatal, early postnatal and neonatal conditions. However, post-neonatal cases of acquired cerebral palsy have also been reported, and were commonly caused by infection. Patients and Methods: The family of a girl from Qatar, who developed severe cerebral palsy caused by submersion injury, consulted us about the possible therapies for her condition. Clinical picture and brain imaging abnormalities are described, and the relevant literatures were reviewed with the aim of suggesting possible evidence-based therapies. Results: At the age of 23 months, a previously healthy girl developed anoxic encephalopathy after experiencing submersion injury. MRI showed evidence of significant hypoxic ischemic injury primarily affecting the deep grey matter, hippocami, mid-brain and the posterior cortex. EEG showed diffuse slowness of cerebral activity and diffuse attenuation of the background without no epileptic abnormalities suggesting diffuse encephalopathy resulting from diffuse cortical injury. At the about age of three and half years, her family consulted us about her condition as she was still showing no awareness to the environment, showing no significant spontaneous movements. She had poor head control. Unable to sit or stand alone, and had a flexed posture. She was on levetiracetam (Keppra), diazepam, and baclofen 30 mg daily. She was still having tracheotomy, and was fed through gastrostomy tube. Conclusion: In this paper, the rare occurrence of severe post-infantile cerebral palsy is described. Emphasis is made on the possibility of using evidence-based multi-factorial therapies in cerebral palsy.

Livedo of the Forearm in the Aftermath of Forearm Erysipelas

Livedo is an ischemic dermopathy caused by vasculopathies or prothrombotic states, and characterized by the violaceous lace-like mottling of the skin. We report on a patient who developed livedo reticularis – livedo racemosa overlap syndrome as a late sequel of erysipelas, the livedo being restricted to the limb segment affected earlier by erysipelas and devoid of systemic vasculopathy. Though erysipelas and livedo are common disorders, we could not find in the literature reports of an occurrence like that observed in this patient. In this case a favorable prognosis of livedo could be predicted. In a different context, livedo may be the alarming signal of an undiagnosed systemic disease.

The Effective Management and Outcome of Hand Burns

Burns is a common public health problem and these injuries can be accidental, suicidal or even homicidal in nature. Hands being the most active part of the body, are often involved in burns. Hand burns represent three percent of body surface area, and are involved in more than 80% of all severe burns. Hand burns predominantly affect young adults and therefore have serious social and financial implications. The hand is one of the most frequent sites of burns scar contracture deformity. The deformities and contractures result in lifelong physical problems and affects the normal functioning of the person.

Design, Simulation, Implementation and Measurement of Respiration Rate by Strain Gauge Sensor and Induction Method

The human body has vital parameters such as respiration, heart rate, and body temperature. Respiratory rate (RR) is a parameter that expresses the rate of respiration per minute. Respiratory activities play an essential role in human life. The rate of respiration has a particular range, which is 14-18 cycles per minute for a healthy and normal person at rest. The oxygen in the blood enters the body during respiration and is expelled as carbon dioxide in return. Any problems with breathing may pose a serious health risk. An abnormal breathing pattern indicates serious illnesses such as cardiac arrest and hospitalization in the intensive care unit (ICU) and when it falls below a certain limit, it indicates a loss of consciousness. This is why it is so imperative to develop devices and methods measuring respiration rates.

An Overvıew of Lower Gastroıntestınal Bleedıng ın Infants and Toddlers: A Revıew Artıcle

Lower gastrointestinal bleeding (LGIB) in infants and toddlers is commonly encountered in clinical practice. There are several factors producing LGIB in these children and are usually managed with regard to the underlying pathology that produces LGIB. Although majority of these bleeding episodes is self limited, certain infants and toddlers with LGIB may necessitate prompt management including urgent surgical intervention. In this review article it is aimed to review the etiology, epidemiology, clinical manifestations and principles of treatment of LGIB in infants and toddlers under the light of relevant literature.

Lipid Profile an Important Risk Factor in Patients with Ovarian Tumors: A-Meta-Analysis

Introduction In the literature ovarian tumors are know to be one of the deadliest gynecological malignancies [1-4]. In US this type of malignancy represents 2.3 % of all cancer-related death and about 4 % of all new cancer cases among women. There are several studies that have reported the role of lipid profiles and it’s role in ovarian tumorigenesis. Fatty acids are essential for cancer cells progression[4-8]. In our study we investigated the true differance in circulating lipid profiles (total cholesterol TC, triglyceride TG, high-density lipoprotein cholesterol HDL, low density lipoprotein cholesterol LDL) among patients with and without ovarian tumors (OT) using a meta-analytical approach. Methods The meta-analysis was conducted using the MOOSE guidelines. PubMed, EMBASE and Cochrane Library were extensively searched (with a period of publication restriction between 2007 and 2019) to indentify published studies using the following keywords: “ total cholesterol ”, “high-density lipoprotein”, “ triglycerides ”, “ low-density lipoprotein ”, “ ovarian cancer”, “ ovarian tumor ”, “ lipid profile ”. The search methodology is shown in Fig. 1 and all references of retrieved articles were searched manually. Results Seven studies, involving 1542 OT cases and 2195 non-cases of OT were included in this meta-analysis and I² statistics ranged between 97 and 99%. Mean circulating TC and HDL were significantly lower among OT cases compared to non-OT cases (P<0.04 and P<0.005). Conclusion There is a modest significant association between circulating HDL and risk of ovarian tumor but it is crucial to elucidate the implications of HDL in tumor manifestations and growth.

Conception and Clinical Efficacy of an Osmotic, Polymeric, Stable Nasal Filmogen Barrier for Preventive Treatment of Allergen and Pollution Induced Rhinitis and Respiratory Symptoms

Background: Pollution induced allergic rhinitis and respiratory symptoms is becoming a major health problem in the world for which still there is no safe and preventive treatment. Objectives: Conceive and evaluate the allergen preventive properties and clinical efficacy of an osmotic, polymeric, stable filmogen spray, called PCNS. Materials and Methods: Amb A 1 (ragweed), Der P 1 and 2 (dust mite), Bet v 1 (birch), Alt a 1 (Alternaria, fungus), and Fel d 1 (cat dander) allergens were exposed at a concentration of 5µg/ml (20 µl per tube) on the polymeric test product film (120 and 240µl layer) and the allergens crossing the barrier were quantified in the agar gel beneath the film. 0.40% HPMC and PBS solutions, tested identically, served as controls. Clinical efficacy of PCNS nasal spray was evaluated in patients suffering from allergic rhinitis and/or respiratory symptoms (29 in test product v/s 15 in saline controls) for 22 days. Nasal, ocular, respiratory symptoms and Rhino conjunctivitis Quality of Life Questionnaire (RQLQ) were measured. Statistical analyses: The normality of the populations was determined by the Shapiro-Wilk test, then statistical analysis was performed by two-tailed Student’s test for comparisons between two groups and the two-way ANOVA followed by the post hoc Bonferroni’s test for comparisons of multiple groups. p<0.05 was considered statistically significant. The analyses were performed with the software GraphPad Prism (version 8.4.2, La Jolla, USA). NS indicates not significant. Results: PCNS polymeric spray blocked the diffusion of all the allergens while 0.40% HPMC was able to prevent diffusion of only Alt a 1 and Fel d 1 allergens. Mean reflective total nasal symptom scores (rTNSS), reflective total ocular symptom score (rTOSS), and respiratory symptoms including effect on wheezing, cough, dyspnea, and chest tightness were moderately improved in the control saline group, but the improvements were nearly twice better in the PCNS group. RQLQ was improved by 23% in saline spray v/s 46% PCNS group. 4/15 patients in saline group v/s 1/29 in PCNS group required rescue medication during the study. PCNS was highly effective in reducing allergen and pollution induced respiratory symptoms. Conclusion: a polymeric, osmotic, and stable nasal barrier against pollutants and allergens represents an innovative approach against pollution induced respiratory symptoms.
