    Cellular Self-Digestion and Persistence in Bacteria

    Abstract: Cellular self-digestion is an evolutionarily conserved process occurring in prokaryotic cells that enables survival under stressful conditions by recycling essential energy molecules. Self-digestion, which is triggered by extracellular stress conditions, such as nutrient depletion and overpopulation, induces degradation of intracellular components. This self-inflicted damage renders the bacterium less fit to produce building blocks and resume growth upon exposure to fresh nutrients. However, self-digestion may also provide temporary protection from antibiotics until the self-digestion-mediated damage is repaired. In fact, many persistence mechanisms identified to date may be directly or indirectly related to self-digestion, as these processes are also mediated by many degradative enzymes, including proteases and ribonucleases (RNases). In this review article, we will discuss the potential roles of self-digestion in bacterial persistence.

    Abstract: The order of singularity near the vertex of bonded joints is one of the main factors responsible fordebonding under mechanical or thermal loading. The distribution of stress singularity field near the vertex ofbonded joints is very important to maintain the reliability of intelligent materials. In this paper, order of stresssingularity at vertex in 3D transversely isotropic piezoelectric dissimilar bonded joints is analyzed. Eigenanalysis based on FEM is used for stress singularity field analysis of piezoelectric bonded joints. The eigenequation is used for calculating the order of stress singularity, and the angular function. The numerical resultshows that the angular functions have large value near the interface edge than the inner portion of the joint.Therefore, there is a possibility to debond and delamination may occur at the interface edge of the piezoelectricbonded joints due to the higher stress and electric displacement concentration at the free edge.DOI: http://dx.doi.org/10.3329/jme.v44i1.19490

    Management of Zygomatico-Maxillary Complex Fracture in Military Dental Centre, Dhaka: A Study of 40 Cases
    Bangladesh Academy of Sciences ; 2017

    Abstract: Introduction: Zygomatic bone is closely associated with the maxilla, frontal, temporal bones which are usually involved when a zygomatic bone fracture occurs. The most common causes of these fractures are from the assaults, road traffic accidents and falls. Aesthetic beauties and functions are greatly hampered with the displacement of the fractured fragments. Objective: To analyze the aetiology, clinical presentations, surgical intervention and complications associated with zygomatic complex (ZC) fractures in a tertiary level healthcare facility. Materials and Methods: This descriptive observational study was carried out in the Oral and Maxillofacial Department, Military Dental Centre, Dhaka during the period of January 2016 to December 2016. Data were obtained from clinical notes and surgical records of the patients using standardized data collection form specifically designed to examine the variables and features of zygomatic complex fractures. Results: Road traffic accidents were the leading cause (75%) of zygomatic fractures. The mean operation time was found 99.5±31.2 minutes with a range from 60 to 125 minutes. Open reduction and two-point internal fixation were employed in more than two-third (67.5%) of the cases. Four (10.0%) patients developed postoperative complications; among them 2(5.0%) cases suffered paresis of temporal branch of facial nerve and trismus. Other complications included paraesthesia, ectropion, scar and palpability of plate. Twenty-five (62.5%) patients were found having limited mouth opening preoperatively and postoperative improvement occurred in 21(52.5%). Thirty three (82.5%) patients had facial asymmetry preoperatively and postoperative improvement occurred in 29(72.5%). Conclusion: More than two-third of the patients received two point fixations. Only four patients out of forty in this study were found having post operative complications. The functional and Aesthetic outcome was found to be fair in terms of improvement in limitation of mouth opening and correction of facial asymmetry.

    Abstract: Introduction: Temporomandibular joint disorders (TMDs) are among the most common disorders in the maxillofacial region which usually present with joint pain, decreased jaw mobility, joint clicking, headache, tinnitus, neck pain etc. There are different modalities of treatment used for the TMDs. These include some conservative and surgical procedures. The main aim is to improve the jaw function and reduction of joint pain. Arthroscopy is a modern diagnostic and effective therapeutic procedure for the TMDs. Objective: To assess the outcome of arthroscopic lavage of Temporomandibular Joint (TMJ) in terms of improvement of jaw function and joint pain in patients suffering from TMDs. Materials and Methods: This prospective study was carried out at the department of Oral and Maxillofacial Surgery, Military Dental Centre, Combined Military Hospital of Dhaka Cantonment from 01 October 2014 to 31 March 2016. Patients were selected consecutively having TMDs and unresponsive to conservative nonsurgical therapy. Total thirty patients of TMDs were selected for study and all the patients were treated with arthroscopic lavage. Objective data were collected including, inter incisal opening, lateral excursion, deviation on opening, tenderness on palpation. A questionnaire in the form of visual analogue scale relating to pain, joint clicking and Jaw mobility were completed by each patient at 1 week,1 month and 6 months post operatively. Results: Among thirty patients, 10 patients were male and 20 patients were female. Mean age of the patient was 42.6±5.79 years. Maximum patients were in the age group of 41-45 years. There was statistically significant improvement in maximum incisal opening and pain score. There was also reduction in Joint clicking and tenderness in maximum patients. Conclusion: The findings of the present study suggested potential utility of arthroscopic lavage in the management of TMDs. Journal of Armed Forces Medical College Bangladesh Vol.12(1) 2016: 88-93

    Pleiotropic actions of phenothiazine drugs are detrimental to Gram-negative bacterial persister cells

    Abstract: Bacterial persister cells are temporarily tolerant to bactericidal antibiotics but are not necessarily dormant and may exhibit physiological activities leading to cell damage. Based on the link between fluoroquinolone-mediated SOS responses and persister cell recovery, we screened chemicals that target fluoroquinolone persisters. Metabolic inhibitors (e.g., phenothiazines) combined with ofloxacin (OFX) perturbed persister levels in metabolically active cell populations. When metabolically stimulated, intrinsically tolerant stationary phase cells also became OFX-sensitive in the presence of phenothiazines. The effects of phenothiazines on cell metabolism and physiology are highly pleiotropic: at sublethal concentrations, phenothiazines reduce cellular metabolic, transcriptional, and translational activities; impair cell repair and recovery mechanisms; transiently perturb membrane integrity; and disrupt proton motive force by dissipating the proton concentration gradient across the cell membrane. Screening a subset of mutant strains lacking membrane-bound proteins revealed the pleiotropic effects of phenothiazines potentially rely on their ability to inhibit a wide range of critical metabolic proteins. Altogether, our study further highlights the complex roles of metabolism in persister cell formation, survival and recovery, and suggests metabolic inhibitors such as phenothiazines can be selectively detrimental to persister cells.

    Abstract: The issue of organizing and orderliness is paramount in Islam, it connotes an act of placing things in its proper place which is otherwise known as Hikmah (wisdom) in Islamic term. Today many organization exist, but are not aware of  the act of organizing, according to Islamic perspective. Some people equate some Muslims or Islamic NGOs with the true Islamic act of governing this could be misconception on their part. Hence this study wishes to elucidate on act or organizing according to the injunctions of Allah and the practice of the holy prophet.  This study employs documentary/library research method and data were collected through both primary and secondary sources. It is found from the study that Islam has its own perfect way of carrying out its organizational function as exemplified by the holy prophet which aims at improving the quality of life and the welfare of the society. It is now the hopes of  all nations to direct attention to the way Islam portrayed organizational management and have a fruitful goal in this world and the hereafter.
