Surface Modification Aspects for Improving Biomedical Properties in Implants:A Review

引用

Acta Metallurgica Sinica(English Letters) 2024年第2期37卷 213-241页

作者： J.Sharath Kumar rakesh Kumar Rajeev Verma Industrial and Production Department Dr B R Ambedkar National Institute of Technology JalandharJalandharPunjab144008India

The primary focus during surgery is to ensure successful implantation by achieving long-term and stable fixation of implants.Orthopaedic surgery is now more focused on the development of novel biomaterials intended to improve implant performance.To obtain a better understanding of metal implants,this article investigated the causes of material failures in certain cases and analysed a few case studies.The interaction between the implant and bone tissue was a crucial aspect of successful implantation,and this study explored the factors influencing this interaction as well as ways to improve it.Several modern approaches used for modifying implant surfaces were systematically illustrated and briefly analysed.Thermal spray coatings were often favoured because of their wide range of coating materials,but other substantial surface modifications(such as friction stir processing and laser surface texturing)were also used for a selection of applications.Notably,implant surfaces with desirable features,such as biocompatibility,antibacterial properties,corrosion resistance,and wear resistance,were essential for optimising implant functionality.This systematic review's main aim is to provide exhaustive reference information and a broad overview to advance the production and design of orthopaedic implants.

Increasing secondary bacterial infections with Enterobacteriaceae harboring bla_(CTX-M-15) and bla_(CMY-6) in patients with bronchogenic carcinoma:an emerging point of concern

引用

Asian Pacific Journal of Tropical Medicine 2011年第1期4卷 5-12页

作者： Mohammed Shahid Abida Malik rakesh bhargava Section of Bacteriology & Molecular Biology Department of Medical MicrobiologyJN Medical College & HospitalAligarh Muslim UniversityAligarh-202 002U.P.India T.B.& Chest Diseases Jawaharlal Nehru Medical College & HospitalAligarh Muslim UniversityAligarh-202002Uttar PradeshIndia

Objective:To look for secondary bacterial infections in bronchogenic carcinoma（BCA） with resistant organisms harboring bla genes considering the paucity of relevant studies.Methods: A total of 137 confirmed cases of BCA and 34 healthy volunteers were studied for the occurrence and prevalence of blaCTX-M and and blaAmpC harboring-enterobacteriaceae.A subset of these patients（n=69） was previously reported for the secondary infection with the Aspergillus species. Bronchoalveolar lavages（BAL） were subjected for bacterial and fungal cultures and the bacterial isolates were screened by multiplex PCRs for the presence of blaCTX-M and blaAmpC.The isolates were also screened for the association of insertion sequence（IS26） by PCR and characterized by RAPD for any clonal relatedness.Results:A total of 143 bacterial isolates were obtained from 137 BAL specimens of BC,patients.The Enterobacteriaceae-isolates were multidrug-resistant showing concomitant resistance to fluoroquinolones and aminoglycosides.Both blaCTX-M and blaAmpC of CIT family were detected in 77.4%and 27.4%isolates,respectively.Sequencing revealed the presence of blaCTX-M-15 and blaCMY-6.Twenty one percent of the isolates were simultaneously harboring blaampC and blaCTX-M-15.IS26 PCR and RAPD typing revealed the presence of diverse bacterial population but no predominant clone was identified.The present study also suggests strong association of aspergillosis with lung cancer and further strengthens the potential use of non-validated serological tests suggested earlier.Conclusions:We emphasize that all patients of bronchogenic carcinoma should also be screened for secondary bacterial infections,along with secondary fungal infections,so as to introduce early and specific antimicrobial therapy and to prevent unwanted deaths.

Balanites aegyptiaca Delile(BA) is an enduring xerophytic woody and spinous flowering tree and is commonly known as desert date or Ingudi(Hingot). It belongs to the family Zygophyllaceae, which is specific to be drought areas of Nigeria, Africa, South Asia and India(Rajasthan). In Ayurveda, this traditional medicinal plant is reported for the management of jaundice, syphilis, yellow fever, metabolic disorders, liver, and spleen problems. The main aim of the review is to compile its medicinal uses and further advancements to showcase the promises inherited in various parts of the plant for the benefit of mankind. As per the literature survey, various researchers have focused on the detailed investigation of BA including the phytopharmacological evidence, chemical constituents, nano-formulations, commercialized products, and clinical trials. Several remarkable scaffolds and isolated compounds like diosgenin, yamogenin, balanitin1/2, balanitin 3, bal4/5, bal6/7, rutin-3-glycosides, 3,7-diglycosides,(3, 12, 14, 16)–(12-hydroxycholest-5-ene-3,16-diyl-bis)-D-glucopyranoside and balanitoside have been identified. Additionally, this traditional plant has been scientifically proven by in vitro and in vivo. Based on the complete review of this plant, most of the compounds have been isolated from the fruit and kernel part. Additionally, based on the literature, a histogram was developed for pharmacological activity in which antidiabetic study was found to be more compared to other pharmacological activity. As a spinous desert dates, this plant needs to be explored more to bring out newer phytochemicals in the management of various diseases.

Extracellular vesicles(EVs)are nano-sized,membranous structures secreted into the extracellular space.They exhibit diverse sizes,contents,and surface markers and are ubiquitously released from cells under normal and pathological conditions.Human serum is a rich source of these EVs,though their isolation from serum proteins and non-EV lipid particles poses challenges.These vesicles transport various cellular components such as proteins,mRNAs,miRNAs,DNA,and lipids across distances,influencing numerous physiological and pathological events,including those within the tumor microenvironment(TME).Their pivotal roles in cellular communication make EVs promising candidates for therapeutic agents,drug delivery systems,and disease biomarkers.Especially in cancer diagnostics,EV detection can pave the way for early identification and offers potential as diagnostic biomarkers.Moreover,various EV subtypes are emerging as targeted drug delivery tools,highlighting their potential clinical significance.The need for non-invasive biomarkers to monitor biological processes for diagnostic and therapeutic purposes remains unfulfilled.Tapping into the unique composition of EVs could unlock advanced diagnostic and therapeutic avenues in the future.In this review,we discuss in detail the roles of EVs across various conditions,including cancers(encompassing head and neck,lung,gastric,breast,and hepatocellular carcinoma),neurodegenerative disorders,diabetes,viral infections,autoimmune and renal diseases,emphasizing the potential advancements in molecular diagnostics and drug delivery.

Role of Serum Procalcitonin Level in Differentiating between Pulmonary Tuberculosis and Community-Acquired Pneumonia

引用

International Journal of Clinical Medicine 2014年第15期5卷 902-909页

作者： Mohammad Shameem Mazhar Alam Shagufta Moin rakesh bhargava Zuber Ahmad Jamal Akhtar Department of Biochemistry Jawaharlal Nehru Medical College Aligarh Muslim University Aligarh India Department of Tuberculosis and Respiratory Diseases Jawaharlal Nehru Medical College Aligarh Muslim University Aligarh UP 202002 India

Pulmonary Tuberculosis (PTB) and Community-Acquired Pneumonia (CAP) are common causes of consolidation patch in chest radiograph. Sputum Z-N staining is positive in 30% to 60% cases only and sputum examination has poor yield in CAP. This study aimed to assess the value of serum Procalcitonin (PCT) levels in patients with Pulmonary Tuberculosis (PTB) and Community-Acquired Pneumonia (CAP). Patients with new opacity in chest radiograph were included in the study. Serum sample were taken at admission and stored. Patient’s diagnosis were confirmed and categorized into pulmonary TB group (32) and community-acquired pneumonia group (23). Their mean PCT level was compared with mean PCT level of 25 controls. Serum procalcitonin levels were found to be significantly elevated in patients of community-acquired pneumonia as compared to patients of pulmonary tuberculosis. In presence of consolidation in x-ray chest, increased level of serum procalcitonin might be used to differentiate pulmonary tuberculosis from community-acquired pneumonia. High level of serum procalcitonin was associated with high mortality rate in community-acquired pneumonia patients.
