Published: July 2021

Vitamins and their coenzymes roles are indispensable for normal functioning of biochemical metabolic pathways. The water soluble vitamin thiamine plays an important role in energy metabolism and its continuous intake is very essential. The source of vitamins can be obtained from many foods like milk, legumes, peas and rice and which is depends on availability, cost. Although most part of the south Indians especially in Tamilnadu the people predominantly depends on rice as a major source of food. So in order to identify the recommended dietary allowance of thiamine the following rice samples were collected from provisional store in Chennai. The collected five rice samples were Deluxe, Bapatla, Karnataka, Rupali ponni rice and Basmati rice. The concentration of thiamine present in the rice was estimated by UV Spectrophotometrically at 246 nm using 0.1M hydrochloride as blank. In order to measure the actual content the high heat and pressure not used and washing is not used. Among the tested 10gm of rice samples, Rupali ponni rice has127 µg which is very less quantity and Bapatla, Deluxe, Karnataka ponni rice has 420 to 430 µg. The high content of was present in Basmati rice-983 µg. Anyhow normal consuming rice quantity is more sufficient to meet Recommended Daily Allowance- RDA level but more washing of rice, prolong boiling will reduce the amount of thiamine content in rice during usage.

Published: July 2021

Physical inactivity (PI) is an established modifiable risk factor of cardiovascular diseases (CVDs) which is the leading cause of global mortality. Researchers and practitioners have been trying to reduce the surge of PI in the population but still, a substantial chunk of the world population is struggling with the issues of PI. This study is aimed at determining the prevalence and associated background factors of PI among CVDs patients. Further, profiles of potentially physically inactive people will also be identified for the future. A cross-sectional study was conducted at Punjab Institute of Cardiology (PIC) Lahore, Pakistan spanning the duration of September 2018 to February 2019. A sample of 230 CVDs patients, using 95% confidence interval (CI), 80% power of test and 5% margin of error was selected in the study. The data on PI was collected using standardized international physical activity questionnaire. In addition to descriptive statistics, bivariate analysis, multiple logistic regression analysis and odds ratios (OR) were also used. The study included 230 participants, in which 156 (68%) were males. The average age of the CVDs patients was 50.11±11.15 years. One hundred thirteen (49%) of the patients were physically inactive. Forward stepwise logistic regression estimated that good subjective financial well-being (OR= 0.560; 95% CI: 0.439-0.714), high years of schooling (OR = 0.932; 95% CI: 0.871-0.998), male gender (OR = 0.336, 95% CI: 0.162-0.698) and advanced ages (OR = 1.041, 95% CI: 1.011-1.072) were the strong factors in determining the likelihood of PI. This study concludes that the prevalence of PI in CVDs patients is alarming and background factors are the strong predictors of PI. These factors can be used to design customized strategies for the reduction of PI which would ultimately help in reducing the incidence of CVDs in the population.

Published: July 2021

Innovative process for treating waste water containing heavy metals often involve technologies for reduction of toxicity in order to meet the technology based standards. The present research is based on the sorption of Cd(II) from synthetic water using Gulmohar fruit shell (GFS). Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscope (SEM) were used for identification of morphology, functional groups of GFS. Equilibrium, kinetic studies were performed by considering the effects of pH, contact time, initial Cd(II) concentration and GFS loading. Results showed that the % removal of Cd(II) ions rised with the rise of pH, contact time and biomass loading and declined with rise of initial Cd(II) concentration. Langmuir isotherm was better described than Fruendlich isotherm. The maximum GFS coverage was 24.03mg/g. Kinetic studies were performed by different kinetic models. Pseudo-second order was excellent suited by kinetics. Thus, it can be concluded that GFS is an efficient biosorbent for the exclusion of Cd(II) from synthetic waste water.

Published: July 2021

Nanomaterials can be used as drug carriers with multiple features, including target delivery triggered by environmental, pH, thermal responses, enhanced biocompatibility, and the ability to cross the blood-brain barrier. Chitosan (CS) is a natural polysaccharide largely obtained from marine crustaceans. It provides drug delivery vector for therapeutic CS and diagnostic CS, owing to its biocompatibility, biodegradability, low toxicity, and structural variability. Derivatives of CS such as quaternized CS, thiolated CS and carboxylated CS have enhanced its effectiveness in oral absorption of macromolecular drugs. This review discusses different forms of nanomaterials generated from CS and its derivatives for controlled drug delivery.

Published: July 2021

Chemical pollutant such as insecticide, pesticide and drugs are mainly used for agriculture, industry and economic development, which are well known for environment pollutant due to its toxicity and persistence in the nature. It can accumulate into the environment and continuously contaminate the food chain which causes threat to the health of consumer including human. Based on all these studies our investigation deals with the effects of two insecticides viz. methyl parathion and diazinon to non target organism like Drosophila melanogaster. In this study we have performed molecular modeling, docking and protein function analysis of different metabolic and physiological enzyme of Drosophila melanogaster such as acetylcholinesterase (AchE), Glutathione S-transferase D1(GST) and Protein kinase C (PKC) with these insecticides of six combinations (AchE + Diazinon, AchE + methyl parathion, GST+Diazinon, GST+Methyl parathion, PKC+Diazinon, PKC+Methyl parathion). Molecular docking results showing best binding affinity for GST+ Methyl parathion with binding energy of -4.79 kcal/mol. Overall, methyl parathion produces efficient binding toward all target protein when compare to diazinon. However, more detailed analysis need to be carried out to have an in-depth understanding of in vivo significance of these bimolecular interactions.

Authors: G. Mahalakshmi , P. Neelusree , M. Kalyani
Published: July 2021

Background: Staphylococcus aureus is Gram positive cocci. The pyogenic bacteria which is responsible for a variety of diseases that ranges in severity from mild skin and soft tissue infections to life-threatening conditions such as endocarditis, pneumonia, and sepsis. There is a scenario of increasing Methicillin-resistant Staphylococcus aureus (MRSA) infections, the macrolide-lincosamide-streptogramin B (MLSB) group of antibiotics they have different structure with same mechanism of action which serves as one good alternative. There is a frequency of increasing Methicillin Resistant Staphylococcus aureus (MRSA) infections and their change in antimicrobial resistance pattern. There is a concern about use of this antibiotic in the presence of Erythromycin resistance because of the possibility of inducible resistance among the members of Macrolide, lincosamide, Strepto-gramin B (MLSB) group. The invitro resistance exhibited by Staphylococcus aureus to erythromycin, Clindamycin, and other drugs of MLSB groups is due to the expression of ribosomal methylases(erm) genes. The detection of inducible Clindamycin resistance can limit the effectiveness of these drugs. Objective of the study: To isolate of Staphylococcus aureus from various clinical samples to differentiate between Methicillin resistant Staphylococcus aureus (MRSA) and Methicillin sensitive Staphylococcus aureus (MSSA) by conventional methods. To detect inducible and constitutive Clindamycin resistance in Staphylococcus aureus isolates by D test. To detect ermA gene responsible for resistance by PCR. Methodology: This cross sectional study was done for a period of six months. Totally 106 Staphylococcus aureus isolates was obtained various clinical samples were processed using standard guidelines. Result: From the 106 isolates of Staphylococcus aureus 67(63.3%) were MSSA and 39(36.7%) were MRSA. D-test was positive in n=9 of the n=21 MRSA and n=17 of the n=85 MSSA, which denotes inducible Clindamycin resistance. N- 9 of MRSA and n=13(22%) of MSSA showed Constitutional Clindamycin resistance. The statistics show that there is a significant Difference in constitutive resistance between MRSA and MSSA. In India ermA gene is most prevalent, out of 22 d-test positive n=13 ermA gene were detected (n=3-MRSA and n=10-MSSA) by using conventional PCR. Conclusion: The MLSB family of antibiotics is one such alternative and CD is preferred. Clinical microbiology laboratories should report inducible Clindamycin resistance in Staphylococcus aureus and D-test can be used as a simple, auxiliary and reliable method to Delineate inducible and constitutive Clindamycin resistance in routine clinical laboratories.

Authors: Ghosh Buddhadeb , Sharma Ravi Kant , Yadav Suman , Randev Ankita
Published: July 2021

Both aluminium and ethanol are pro-oxidants and toxic. Uncontrolled use of aluminium and increasing trends of ethanol consumption in India increased the chance of coexposure to aluminium and ethanol. There are possibilities, that both of them follow common mechanisms to produce reproductive toxicity. The present study was planned to identify the effects of aluminium administration on the microscopic structure of ovary and to clarify any possible protection conferred by the concomitant administration of ethanol. Sixteen female rats divided into one control and three experimental groups exposed to aluminium (4.2mg/kg body weight) and ethanol (1gm/kg body weight) for 3 months. After the exposure period, ovaries were processed for light microscopic examination. Ovary showed significant atretic follicles with degenerated ova and vacuolation. Rupture of zona pellucida in oocyte seen in aluminium treated animals. Ethanol treated group showing absence of growing follicles, increased large corpora lutea. Dilated and congested vessels were observed in the growing follicle. The effects of combined administration of aluminium and ethanol treated groups showed with acute degeneration of growing follicles, with desquamation of pyknotic granulosa cells and degenerated oocyte. Multiple vacuoles of degenerated granulosa cells with dilated congested vessels and edema seen. Hyaline material seen inside the degenerating follicles. It has been suggested that the ethanol induced augmentation of impacts of aluminium on the Ovary.

Authors: Pal Jain Ashutosh , Pratap Choudhary Gajendra
Published: July 2021

Background: The purpose of this study was to evaluate the antioxidant potential of Sphaeranthus indicus and Abrus precatorius leaves. Methods: Both plant leaves powder was exhaustively extracted by soxhlet apparatus with various solvents of increasing order of polarity, petroleum ether followed by chloroform, methanol and water. The total phenol, tannins and flavonoids content were determined spectrophotometrically. Quantitative estimation of phenolic and flavonoid compounds in the extracts was estimated by using the Folin–Ciocalteu reagent and aluminum chloride colorimetric method respectively. The antioxidant potential of all these extracts was evaluated by reducing ability assay and DPPH radical scavenging assay with vitamin C as a standard. The antioxidant activity increased with dose dependence of extracts (from 20 to 200μg/ml). Results: The order for reducing power of extracts was recorded as vitamin C > methanol > water ≈ chloroform > petroleum ether and the same order was found in the DPPH assay having 50% inhibitory concentration (IC50) values. The results revealed that the methanolic extract exhibited the highest percent inhibition of the reducing ability and DPPH radical scavenging assay as compared to the other extracts of both plant. Moreover, methanolic extract showed concentration dependent significant scavenging of DPPH, especially with S. indicus [IC50 values 112.23±0.39 μg/ml] and A. precatorius [IC50 values 101.44±0.41μg/ml], while that of the standard was 13.45±0.37μg/ml (vitamin C). Methanolic extract showed phenolics, flavonoids and tannins contents were significantly higher than all the extracts investigated in both plant. Conclusions: A correlation between the antioxidant activity and the total phenolic contents of the extracts indicated that phenolic compounds were the dominant contributors to the antioxidant activity of the plant. The results suggest that methanolic leaves extract of S. indicus and A. precatorius are source of natural antioxidants and free radical scavenging capability.

The Physiology of Lens Transparency: New Insights into Presbyopia and Cataract
Authors: Donaldson Paul
Published: July 2021

The majority of cases of age-related vision loss in the world today are associated with the lens pathologies presbyopia and cataract. While it is believed these two lens pathologies are linked by oxidative damage to lens proteins, antioxidant based therapies have to date proven ineffective in slowing the onset of either presbyopia or cataract. Our confirmation of the existence of a lens microcirculation system, which generates a circulating flux of water, provides an alternative view not only to understand the onset of presbyopia and cataract, but also opens up new therapeutic pathways to treat presbyopia and cataract using antioxidants. We have shown that movement of water through the lens generates a substantial and highly regulated pressure gradient, delivers nutrients and antioxidants to the lens center, controls lens water content and volume, and maintains overall lens optics. However, with advancing age, these processes become dysfunctional. During middle age, lens pressure and water content increase and the ability of the lens to accommodate is lost. In the elderly, the failure of the system to control lens volume and to deliver antioxidants results in diabetic cortical and nuclear cataract, respectively. It follows therefore that by studying how water transport is regulated in the lens, we can develop novel anti-oxidant-based pharmacological approaches to maintain the optical properties and transparency of the lens and thereby prevent the onset of presbyopia and cataract. In this seminar we will highlight the multidisciplinary approach that we are adopting to test our central hypothesis that age-related changes to lens water content and transport are the initiating causes of the loss of accommodation and the onset of presbyopia in middle age, and the loss of transparency that manifests as either cortical, or nuclear cataract, in the elderly.

El decir-hacer en una ceremonia de Okolun
Authors: Castro-Ramírez Luis Carlos
Published: July 2021

En los sistemas religiosos de inspiración afro, como el espiritismo cruzao, la santería, el palo monte y el vodou, entre otros, la oralidad ocupa un lugar relevante. Esto se puede apreciar en diferentes niveles, como la enseñanza de las tradiciones, las prácticas rituales y el quehacer religioso, aspectos que se encuentran íntimamente vinculados. Los mitos, las plegarias y los cantos que aparecen en la escena ritual vehiculizan las posibilidades de transformar la realidad fenoménica de los participantes. De aquí se desprende la idea de un decir-hacer, lo cual indica que la palabra no solo es nominativa o enunciativa; la palabra es acción. Sin ella los objetos, las imágenes y las plantas utilizados con fines terapéuticos serían tan solo objetos desprovistos de poder. Así, a partir del trabajo etnográfico y narrativo basado en el trabajo de campo realizado en Cuba en 2013 durante una ceremonia de entrega de Olokun, se discutirá el lugar de la palabra dentro de la santería.

Published: July 2021

Introduction : le paludisme est un problème de santé publique au Mali. Cependant il est si rare chez le nouveau-né que sa recherche n'est pas systématique chez ce dernier même fébrile.

Observation : il s'agissait un nouveau-né prématuré de 21 jours admis pour fièvre à la néonatologie de l'Hôpital du Mali. Le diagnostic a été posé au test rapide (TDR) du paludisme. Un traitement comprenant l'artésunate, la transfusion de concentré globulaire et la perfusion du sérum glucosé 10% a été institué. L'évolution a été marquée par l'apyrexie, la reprise de l'alimentation et du poids, la diminution de la parasitémie et l'augmentation du taux de l'hémoglobine.

Conclusion : le TDR du paludisme doit être systématique chez les nouveau-nés fébriles en zone d'endémie palustre pour ne pas passer à côté d'un paludisme néonatal.

Les dossiers de tous les cas de tétanos âgés de 18 ans et plus répondant aux critères d'inclusion ont été inclus. Les données ont été saisies sur Word et analysées sous le logiciel SPSS. Le test X² a été utilisé pour la comparaison des variables qualitatives avec un seuil de significativité p≤0,05.Résultats : trente-cinq cas de tétanos ont été colligés sur 972 hospitalisations soit une prévalence de 3,6%. La totalité des patients était des hommes. Aucun patient n'avait un calendrier vaccinal à jour. La majorité des portes d'entrée tégumentaires était causée par des accidents de la voie publique (soit 31,7%). Les cultivateurs étaient les plus exposés avec 37,1%. Les comorbidités (15 cas) étaient le paludisme, l'hypertension artérielle et le diabète avec respectivement 53,3% ; 33,3% ; et 13,3%. La létalité du tétanos était de 25,7%. Les facteurs associés de façon significative à la mortalité était l'hypertension artérielle, les complications pulmonaires et les fausses routes.Conclusion : Cette étude montre que les comorbidités et les complications ont majoré la létalité du tétanos. La prise en charge rapide et correcte des complications et des comorbidités pourra avoir un impact positif sur le pronostic des patients atteints de tétanos.

Lithium is an economically important element that is increasingly extracted from brines accumulated in continental basins. While a number of studies have identified silicic magmatic rocks as the ultimate source of dissolved brine lithium, the processes by which Li is mobilized remain poorly constrained. Here we focus on the potential of low-temperature, post-eruptive processes to remove Li from volcanic glass and generate Li-rich fluids. The rhyolitic glasses in this study (from the Yellowstone-Snake River Plain volcanic province in western North America) have interacted with meteoric water emplacement as revealed by textures and a variety of geochemical and isotopic signatures. Indices of glass hydration correlate with Li concentrations, suggesting Li is lost to the water during the water-rock interaction. We estimate the original Li content upon deposition and the magnitude of Li depletion both by direct in situ glass measurements and by applying a partition-coefficient approach to plagioclase Li contents. Across our whole sample set (19 eruptive units spanning ca. 10 m.y.), Li losses average 8.9 ppm, with a maximum loss of 37.5 ppm. This allows estimation of the dense rock equivalent of silicic volcanic lithologies required to potentially source a brine deposit. Our data indicate that surficial processes occurring post-eruption may provide sufficient Li to form economic deposits. We found no relationship between deposit age and Li loss, i.e., hydration does not appear to be an ongoing process. Rather, it occurs primarily while the deposit is cooling shortly after eruption, with δ18O and δD in our case study suggesting a temperature window of 40° to 70°C.

Introduction:

This study sought to determine the effect of trauma fellowship training on the surgical decision to fix or revise to distal femoral replacement in periprosthetic distal femur fractures.

Methods:

An anonymous online survey including nine cases of geriatric periprosthetic distal femur fractures was distributed through the Orthopaedic Trauma Association website. Respondents were asked whether they would recommend fixation or revision to distal femoral replacement. Fractures were classified by the location relative to the anterior flange (proximal or distal) and the presence or absence of comminution. Recommendations were compared between type of fellowship completed (trauma, arthroplasty, or both), practice setting, and number of periprosthetic distal femur fractures treated monthly.

Results:

One hundred fifty-one surgeon survey responses were included. Completion of a trauma fellowship was associated with a higher likelihood of recommending fixation for any periprosthetic distal femur fracture compared with arthroplasty training (odds ratio [OR] 2.55, 95% confidence interval [CI] 1.97 to 3.29; P < 0.0001). Disagreement was significant for comminuted proximal (OR 6.90, 95% CI 3.24 to 14.68; P < 0.0001), simple distal (OR 20.90, 95% CI 6.41 to 67.71; P < 0.001), and comminuted distal fractures (OR 2.47, 95% CI 1.66 to 3.68; P < 0.0001). Dual fellowship-trained surgeons were less likely to recommend fixation than surgeons who completed a trauma fellowship alone (OR 0.60, 95% CI 0.39 to 0.93; P = 0.027) and more likely to recommend fixation than surgeons who completed an arthroplasty fellowship alone (OR 1.70, 95% CI 1.13 to 2.63; P = 0.012). Surgeons who treat three or more periprosthetic distal femur fractures monthly showed a significant preference for fracture fixation compared with lower volume surgeons (OR 2.45, 95% CI 1.62 to 3.68; P < 0.0001).

Discussion:

Fellowship-trained trauma surgeons show a notable preference for fracture fixation over distal femoral replacement for periprosthetic distal femur fractures, as compared with arthroplasty-trained surgeons. Additional research is needed to clarify surgical indications that maximize outcomes for these injuries.
The Orthopaedic Resident Selection Process: Proposed Reforms and Lessons From Other Specialties
Authors: London Daniel A. , Zastrow Ryley K.
Published: July 2021

Introduction:

Proposals for substantive reforms to the orthopaedic resident selection process are growing, given increasing applicant competitiveness, burgeoning inefficiencies and inequities of the current system, and impending transition of Step 1 to pass/fail. The COVID-19 pandemic has further catalyzed the need for reforms, offering unprecedented opportunities to pilot novel changes. However, a comprehensive collation of all proposed and implemented orthopaedic reforms is currently lacking. Thus, we aimed to characterize proposed orthopaedic-specific resident selection reforms in the context of reforms implemented by other specialties.

Methods:

EMBASE, MEDLINE, Scopus, and Web of Science databases were searched for references proposing reforms to the orthopaedic resident selection process published from 2005 to 2020. An inductive approach to qualitative content analysis was used to categorize reforms.

Results:

Twenty-six articles proposing 13 unique reforms to the orthopaedic resident selection process were identified. The most commonly proposed reforms included noncognitive assessments (n = 8), application caps (n = 7), standardized letters of recommendation (n = 5), program-specific supplemental applications (n = 5), creation of a centralized database of standardized program information (n = 4), use of a standardized applicant composite score (n = 4), and a moratorium on postinterview communication (n = 4). Importantly, nearly all of these reforms have also been proposed or implemented by other specialties.

Discussion:

Numerous reforms to the orthopaedic resident selection process have been suggested over the past 15 years, several of which have been implemented on a program-specific basis, including noncognitive assessments, supplemental applications, and standardized letters of recommendation. Careful examination of applicant and program experiences and Match outcomes after these reforms is imperative to inform future directions.
Coming to Grips with Bologna: Change and Student Empowerment in Transforming Classes into an Effective Learning Environment
Authors: Kindelan Paz
Published: July 2021

With the advent of the Bologna Process to develop higher education in the European Union, university teachers and students have gone through a process of change. This change required an adjustment to the demands of higher education reform governed by European convergence. However, the resulting transformations in pedagogical practice have ostensibly affected not only teacher-student attitudes and relationships but also the academic culture.

Within the new educational paradigm, the shift to a student-centered pedagogy has meant the empowering of individual students providing them with the opportunity to direct their own learning. However, the issue now is how to address and exercise student empowerment in the real-life class. This study is an investigation into the role of teachers to strike a balance between the forces pushing them to adapt to the new pedagogical framework and the need to improve student self-reliance and ownership of learning. It concludes by reaffirming the advantages of applying an empowerment-based approach, already recognized by current research, that enhances teacher and students relations in an effective learning environment.
