FREHSWATER FISH OF LAKES AND IT’S INLET RIVERS IN SULAWESI TENGAH PROVINCE, INDONESIA
Authors: Herjayanto Muh. , Gani Abdul , Adel Yeldi S , Suhendra Novian
Published: April 2020

Sulawesi Tengah Province (Sulteng) is in the Wallacea region wich have endemic fish. In addition, the government has also introduced fish for the welfare of community. So far the records of freshwater fish in Sulteng have not been well summarized. Therefore, we explore the results of previous studies fish species in 11 lakes and their inlet rivers in Sulteng. The lake (L) is L. Bolano (Bolanosau), L. Lindu, L. Poso, L. Rano, L. Rano Kodi and L. Rano Bae, L. Sibili, L. Talaga (Dampelas), L. Kalimpa’a (Tambing), L. Tiu and L. Wanga. In addition, we also observed fish in seven lakes between 2012-2019. Fishing uses cast net, seine net, gillnet, and hook and line. Summary and observation result showed that there were 18 families and 27 genera of fish in 11 lake and their inlet rivers in Sulteng. Then there are 15 endemic species in 3 habitats (Lindu, Poso and Tiu), namely Adrianichthys 4 species, Oryzias 6 species, Mugilogobius 2 species and Nomorhamphus 3 species. Introduced fish as many as 23 species, Oreochromis niloticus the most found (8 lakes). Lake Poso (30 species) has the most fish species. Utilization of fish in 11 lake as consumption fish and ornamental fish. Especially for endemic fish, in situ (habitat) and / or ex situ (aquaculture) conservation needs to be carried out in order to remain sustainable. Through aquaculture, the breeding of endemic species that have the potential as ornamental fish and/or consumption can be avoided from exploitation (overfishing) in nature.

The Idea of Noosphere in the Сontext of Modern Transformations
Authors: Brizhak Olga V. , Ermolenko Alexandr A.
Published: April 2020

The idea of a noosphere for the first time formulated in V. Vernadsky's works in the 1940s in the recent years attracts attention of participants of the different trends of scientific search as it has the considerable hidden potential in a research of modern transformations. The creator of a noosphere – the Humanity, presented as the powerful geological force allocated with consciousness, getting to know and transforming the Nature itself is involved in deep transformations many results of which are unexpected for him and bring him problems and additional obligations. Effective implementation of informative opportunities of the idea of a noosphere assumes expansion of space of scientific search and overcoming cross-disciplinary borders. At the focus of research of authors: representation of a noosphere as the system endowed with the energy which generate other types of energy and involved in the difficult process of transformation of energy proceeding in space; structure of a noosphere and its basic components; a problem of responsibility of the Humanity in all its subject forms by results of activity, including, responsibility in its noosphere scale, creation of adequate mechanisms of implementation of such responsibility in the conditions of forming of the global market. The chimeric entities and the anti-systems accompanying them arise in the movement of a noosphere. Through the optics of the idea of a noosphere authors consider key problem nodes and contradictions of modern conversions, estimate the effects arising at the different levels of these processes, offer applied means for a solution of the tasks rising here. Article provides recommendations on upgrading the state policy in social and economic transformations. The authors’ results belong to one of the new and perspective directions of cross-disciplinary scientific search that causes essential novelty and the debatable nature of the provisions presented in article, conclusions and recommendations. During the research heuristic resources of a number of modern scientific theories were used: biospheres, passionarity, cognitive economy, social and economic transformations, human capital, ecology, etc.
A New Wave of Globalization, Public Policy Options and Possible Actions by Russian Companies
Authors: Gurkov Igor B.
Published: April 2020

The article presents the process of globalization, i.e. “the growing interdependence between nations” as a superposition of particular elements of mutual dependence of nations over the past several thousand years. Four waves of globalization, following one another, namely – trade, financial, industrial and innovation globalization are presented. The main features of innovation globalization are indicated: 1) increasing the degree of research internationalization in the natural and technical sciences, 2) transfer abroad of research and development units by the large international corporations, 3) active purchase of promising technologies and prototypes of new products and processes for their production together with their developers, that is, the purchase of companies that have created prototypes of promising products or technologies (startups); 4) a growing stream of “reverse innovations” – when innovations are created in foreign manufacturing units of multinational corporations, often while implementing joint projects with other firms. It is indicated that all these phenomena are observed in Russia. Recommendations are given in the field of strategies of industrial corporations on the more active involvement of Russia in global innovation processes: 1) the participation of the Russian firms in creation of new industrial enterprises in the developed countries in cooperation with local companies; 2) the purchase of domestic and foreign startups that have developed the most promising technologies in the new areas; 3) expanding the circle of employees familiar with the most advanced production practices; 4) leasing at attractive rates of production and office space to foreign enterprises that own advanced technologies and forms of organization; 5) contract design and contract manufacturing abroad. It is concluded that these and other measures are capable of transferring Russian enterprises from an object to an active subject of the new wave of globalization.
To the Question of Giffen's Parafox
Authors: Tsurikov Vladimir I.
Published: April 2020

The article is devoted to the construction and analysis of the simplest mathematical model illustrating the Giffen’s effect and the reasons and conditions for its manifestation. We analyse erroneous, but widely spread, ideas about Giffen’s goods as a good, the demand for which grows due to its relative cheapening against the rising prices for all consumed goods. Under the model it is shown that any good can be both valuable and of little value, at least if it has a more expensive substitute. This property is not an intrinsic and inalienable property of one or another good. The certain property is given to any good by a specific consumer due to its personal preferences and under the influence of existing prices. Inferior good, including such, the consumption of which is available only to an individual with a high level of income, may turn out to be a product of Giffen. Therefore, the consumption of Giffen goods cannot be considered as evidence of a low standard of living for the consumer. Because of the solution of the standard task on the consumer choice, it is shown that the increase in demand for an inferior good when its price is growing, which is the essence of the Giffen paradox, is the result of optim. It is shown that for the manifestation of the Giffen effect it is necessary that the amount of funds allocated by the consumer for acquiring low value good and its more expensive substitute gets into a certain rather narrow range of values.

Authors: Ionela Raluca Maxim
Published: April 2020

The aeronautical profession of fighter pilots on supersonic aircraft is strongly connected to the motivation, performance and excellence achievement-striving. The supersonic pilot represents the highest and most desirable position in the air force. Research showed that their selection is made by choosing the potential elite candidates after testing the physical, mental abilities and personality traits specific to this profession. The present research examined the personality trait of conscientiousness with achievement-striving facet in fighter pilots on supersonic aircrafts, by using the “IPIP NEO” (International Personality Item Pool NEO) based on Big Five by comparison of two groups, one of fighter pilots on supersonic aircraft and one of non-pilots. The results indicated that fighter pilots on supersonic aircraft have higher level of excellence achievement striving in their performance, they tend to be more competitive to become the best and the desire for victory is needed in their highly risky air missions.

Published: April 2020

We evaluate the mRNA expression of monocarboxylate transporters 1 and 4 (MCT1 and MCT4) in skeletal muscle (soleus, red and white gastrocnemius), heart and liver tissues in mice submitted to a single bout of swimming exercise at the maximal lactate steady state workload (MLSSw). After 72 h of MLSS test, the animals were submitted to a swimming exercise session for 25 min at individual MLSSw. Tissues and muscle samples were obtained at rest (control, n=5), immediately (n=5), 5 h (n=5) and 10 h (n=5) after exercise for determination of the MCT1 and MCT4 mRNA expression (RT-PCR). The MCT1 mRNA expression in liver increased after 10 h in relation to the control, immediate and 5 h groups, but the MCT4 remained unchanged. The MCT1 mRNA expression in heart increased by 31 % after 10 h when compared to immediate, but no differences were observed in relation to the control group. No significant differences were observed for red gastrocnemius in MCT1 and MCT4 mRNA expression. However, white gastrocnemius increased MCT1 mRNA expression immediately when compared to rest, 5 and 10 h test groups. In soleus muscle, the MCT1 mRNA expression increased immediately, 5 and 10 h after exercise when compared to the control. In relation to MCT4 mRNA expression, the soleus increased immediately and 10 h after acute exercise when compared to the control group. The soleus, liver and heart were the main tissues that showed improved the MCT1 mRNA expression, indicating its important role in controlling MLSS concentration in mice.
Effects of Atrial Natriuretic Peptide on Rat Ventricular Fibroblasts During Differentiation Into Myofibroblasts
Authors: MOUBARAK M. , MAGAUD C. , SALIBA Y. , CHATELIER A. , BOIS P. , FAIVRE J.-F. , FARÈS N.
Published: April 2020

Atrial natriuretic peptide antifibrotic properties are mainly described in cardiac myocytes or in induced cardiac myofibroblasts (Angiotensin II or TGF-β induced differentiation). In the present work, we investigate the effects of ANP/NPRA/cGMP system in modulating rat cardiac fibroblasts function. Cardiac fibroblasts were isolated from adult Wistar male rats and cultured in the presence of serum in order to induce fibroblasts differentiation. Cultures were then treated with ANP (1 µM), 8-Br-cGMP (100 µM) or IBMX (100 µM), a non-specific phosphodiesterases inhibitor. ANP significantly decreased proliferation rate and collagen secretion. Its effect was mimicked by the cGMP analog, while combining ANP with 8-Br-cGMP did not lead to additional effects. Moreover intracellular cGMP levels were elevated when cells were incubated with ANP confirming that ANP intracellular pathway is mediated by cGMP. Additionally, immunoblotting and immunofluorescence were used to confirm the presence of guanylyl cyclase specific natriuretic peptide receptors A and B. Finally we scanned specific cGMP dependent PDEs via RT-qPCR, and noticed that inhibiting all PDEs led to an important decrease in proliferation rate. Effect of ANP became more prominent after 10 culture days, confirming the importance of ANP in fibroblasts to myofibroblasts differentiation. Uncovering cellular aspects of ANP/NPRA/cGMP signaling system provided more elements to help understand cardiac fibrotic process.
Mountains as a Global Heritage: Arguments for Conserving the Natural Diversity of Mountain Regions
Authors: Chakraborty Abhik
Published: April 2020

This concise review posits the urgent need for conserving the natural diversity of mountain environments by envisioning mountains as a global natural heritage. Mountains are recognized as cradles of biodiversity and for their important ecosystem services. Mountains also constitute the second most popular outdoor destination category at the global level after islands and beaches. However, in the current age of accelerating global environmental change, mountain systems face unprecedented change in their ecological characteristics, and consequent effects will extend to the millions who depend directly on ecosystem services from mountains. Moreover, growing tourism is putting fragile mountain ecosystems under increasing stress. This situation requires scientists and mountain area management stakeholders to come together in order to protect mountains as a global heritage. By underlining the salient natural diversity characteristics of mountains and their relevance for understanding global environmental change, this critical review argues that it is important to appreciate both biotic and abiotic diversity features of mountains in order to create a notion of mountains as a shared heritage for humanity. Accordingly, the development of soft infrastructure that can communicate the essence of mountain destinations and a committed network of scientists and tourism scholars working together at the global level are required for safeguarding this shared heritage.
A New Evaluation Methodology for Quality Goals Extended by D Number Theory and FAHP
Authors: Mo Hongming
Published: April 2020

Evaluation of quality goals is an important issue in process management, which essentially is a multi-attribute decision-making (MADM) problem. The process of assessment inevitably involves uncertain information. The two crucial points in an MADM problem are to obtain weight of attributes and to handle uncertain information. D number theory is a new mathematical tool to deal with uncertain information, which is an extension of evidence theory. The fuzzy analytic hierarchy process (FAHP) provides a hierarchical way to model MADM problems, and the comparison analysis among attributes is applied to obtain the weight of attributes. FAHP uses a triangle fuzzy number rather than a crisp number to represent the evaluation information, which fully considers the hesitation to give a evaluation. Inspired by the features of D number theory and FAHP, a D-FAHP method is proposed to evaluate quality goals in this paper. Within the proposed method, FAHP is used to obtain the weight of each attribute, and the integration property of D number theory is carried out to fuse information. A numerical example is presented to demonstrate the effectiveness of the proposed method. Some necessary discussions are provided to illustrate the advantages of the proposed method.
On the Role of Nanofluids in Thermal-hydraulic Performance of Heat Exchangers—A Review
Authors: Almurtaji Salah , Ali Naser , Teixeira Joao A. , Addali Abdulmajid
Published: April 2020

Heat exchangers are key components in many of the devices seen in our everyday life. They are employed in many applications such as land vehicles, power plants, marine gas turbines, oil refineries, air-conditioning, and domestic water heating. Their operating mechanism depends on providing a flow of thermal energy between two or more mediums of different temperatures. The thermo-economics considerations of such devices have set the need for developing this equipment further, which is very challenging when taking into account the complexity of the operational conditions and expansion limitation of the technology. For such reasons, this work provides a systematic review of the state-of-the-art heat exchanger technology and the progress towards using nanofluids for enhancing their thermal-hydraulic performance. Firstly, the general operational theory of heat exchangers is presented. Then, an in-depth focus on different types of heat exchangers, plate-frame and plate-fin heat exchangers, is presented. Moreover, an introduction to nanofluids developments, thermophysical properties, and their influence on the thermal-hydraulic performance of heat exchangers are also discussed. Thus, the primary purpose of this work is not only to describe the previously published literature, but also to emphasize the important role of nanofluids and how this category of advanced fluids can significantly increase the thermal efficiency of heat exchangers for possible future applications.
Quantum Electromagnetic Finite-Difference Time-Domain Solver
Authors: Na Dong-Yeop , Chew Weng Cho
Published: April 2020

We employ another approach to quantize electromagnetic fields in the coordinate space, instead of the mode (or Fourier) space, such that local features of photons can be efficiently, physically, and more intuitively described. To do this, coordinate-ladder operators are defined from mode-ladder operators via the unitary transformation of systems involved in arbitrary inhomogeneous dielectric media. Then, one can expand electromagnetic field operators through the coordinate-ladder operators weighted by non-orthogonal and spatially-localized bases, which are propagators of initial quantum electromagnetic (complex-valued) field operators. Here, we call them QEM-CV-propagators. However, there are no general closed form solutions available for them. This inspires us to develop a quantum finite-difference time-domain (Q-FDTD) scheme to numerically time evolve QEM-CV-propagators. In order to check the validity of the proposed Q-FDTD scheme, we perform computer simulations to observe the Hong-Ou-Mandel effect resulting from the destructive interference of two photons in a 50/50 quantum beam splitter.

Healthscaping a Medieval City: Lucca’s Curia viarum and the Future of Public Health History,” Urban History 40: 395-415
Authors: Geltner Guy
Published: April 2020

In early fourteenth-century Lucca, one government organ began expanding its activities beyond the maintenance of public works to promoting public hygiene and safety, and in ways that suggest both a concern for and an appreciation of population-level preventative healthcare. Evidence for this shift (which is traceable in and beyond the Italian peninsula) is mostly found in documents of practice such as court and financial records, which augment and complicate the traditional view afforded by urban statutes and medical treatises. The revised if still nebulous picture emerging from this preliminary study challenges a lingering tendency among urban and public health historians to see pre-modern European cities as ignorant and apathetic demographic black holes.
“Coping in Medieval Prisons,” Continuity and Change 23: 151-72
Authors: Geltner Guy
Published: April 2020

Based on archival research in several Italian city-states, this article examines medieval prison life, its attendant pains, and inmate coping strategies by substantially engaging the variety of scholarship on modern incarceration. It demonstrates the limited degree to which current hardships overlap with those of earlier forms of captivity, and underscores the diversity of inmates' social positions in both eras. Medieval prisoners were marginalized, but they avoided social liminality (a major present-day risk) largely thanks to their visibility, accessibility, and frequent interaction with free society.
“Mendicants as Victims: Scale, Scope, and the Idiom of Violence,” Journal of Medieval History 36: 126-41
Authors: Geltner Guy
Published: April 2020

This article establishes the scale of violence perpetrated against mendicant friars in thirteenth- and fourteenth-century Europe, and provides a list of these events in an on-line appendix. It underscores and analyses the wide variety of contexts in which such incidents took place and examines the ramifications for the history of the mendicant orders and medieval urban society generally. Violence was a subtler form of communicative action than is sometimes recognised, and the paper points to the inverse relationship between power and violence in medieval urban conflicts.
"Introduction: Debating Corruption and Anticorruption in History, "in Anticorruption in History: Antiquity to the Modern Era (Oxford University Press, 2017), 1-17
Authors: Kroeze D.B.R. , Vitória André Miguel de Cunha , Geltner Guy
Published: April 2020

The introduction to this volume focuses on historiography, methodology and conclusions. It explains how anticorruption has seldom been treated as a historical subject except as the occasional counterpart of corruption; instead, policy makers and social scientists have linked anticorruption and good government to the historical development of democracy and Weberian-style bureaucracy, all emblematic aspects of countries consistently ranked among the least corrupt in the world. This hypothesis has struck most historians involved in this volume as either circular or at least teleological. In response, they have sought to show that efforts to control corruption are not an exclusively Western-European or modern phenomenon; rather, the history of anticorruption is far more complex and diverse. In addition, they also outline how anticorruption is an inherently political issue, related to changing power relations and acute political crises, and that fighting corruption is historically difficult to evaluate in terms of success or failure.

En el presente artículo me propongo demostrar dos tesis fundamentales: 1) que el proyecto warburguiano de una “psicología histórica de la expresión humana”, basamento teórico y directriz del Atlas Mnemosyne, debe ser entendido como una psico-arqueología de lo humano; y 2) que la locura de Warburg es la experiencia de la condición extra-humana de la psiquis histórica, es decir la constatación patológica de que lo humano no es lo otro del Monstrum sino el mismo Monstrum domesticado.

Introduction: Febrile convulsion (FC) is the most common seizure disorder in childhood. Few studies focused on epidemiologic characteristics of urinary tract infections accompanied by FC. Objectives: To evaluate prevalence and incidence rates of FC among children with urinary tract infection. Patients and Methods: An observational study in epidemiology was performed in nephrology clinic of a tertiary children hospital from June 2002 to 2016. Totally 1242 cases were followed and those aged 6-60 months enrolled in the study. Demographic characteristics were compared between patients with and without FC. Results: 784 cases including 704 girls (89.8%) and 80 boys (10.2%) enrolled. Twenty-five patients (3.18%) presented with FC. FC occurred in 25 of 503 cases (5%) with febrile urinary tract infection. Twenty girls and 5 boys were in FC and 684 girls and 75 boys were in non-FC groups (P= 0.1). The average age in FC and non-FC groups were 15.52±8.4 and 25.16± 16 months respectively (P=0.004). Patients were divided into 2 age sub-groups: 6-24 and 26-60 months. A significantly higher number of cases in FC compared with non-FC group were in age subgroup of 6-24 months (P=0.028). Conclusion: Our study revealed a prevalence rate of 3.18% and an incidence rate of 5% for FC among children with urinary tract infection. Also FC subjects had a significantly younger age at presentation than non-FC cases. We found that FC as presentation of urinary tract infection occurred up to 3 years old, and there is no significant gender difference between FC and non-FC cases

Introduction: Benign prostate hyperplasia, pathophysiology contributes to bladder outlet obstruction due to functional obstruction caused by gland size enlargement resulting in the lower urinary tract symptoms (LUTS). Objectives: To determine the correlation of the prostate volume with surgical outcomes and postoperative LUTS in patients with benign prostatic hyperplasia (BPH) undergoing transurethral resection of the prostate (TURP). Patients and Methods: Patients with BPH who were refractory for medical treatment enrolled in the study. Patients divided into three groups with attention to their prostate volume conducted by transabdominal ultrasonography. To evaluate patients’ LUTS, the International Prostate Symptom Score (IPSS) questionnaire was filled for all patients preoperatively and during the first and third months follow up sessions. Results: In the current study, mean age of the patients was 66.92 ± 1.08 years. Of 111 patients, eight patients (7.2%) had prostate volume less than 30 cc, 59 patients (53.2%) had prostate volume between 30-60 cc, and 44 patients (39.6%) had prostate volume more than 60 cc. During first month postoperative, mean decrease in IPSS scores in patients with prostate volume less than 30 cc, prostate volume between 30–60 cc and prostate volume more than 30 cc were 27.72 ± 3.53, 27.32 ± 3.37 and 27.45 ± 2.87, respectively. The ANOVA test showed no significant difference between the groups (P= 0.93). Mean decrease in IPSS score during third month postoperative, had no significant difference between the three groups, too (P=0.71). Symptoms alleviation observed in 94.6% and 95.5% of the patients, during first and third months follow-up, respectively. Conclusion: There was no correlation between the IPSS scores decrease and patients’ symptoms recovery and preoperative prostate volume in patients with BPH who underwent TRUP.

Methamphetamine is a highly addictive drug that acts as a stimulant for the central nervous system. It increases alertness and physical activity but can cause cardiac dysrhythmias, hypertension, hallucinations and violent behavior. The excretion rate of methamphetamine by the kidney can be seriously altered by urinary pH. Methamphetamine is a weak base, consequently, the proportion of the excreted amount of unchanged drug can vary from as little as 2% in alkaline (pH ≥8.0) to 76% in acidic urine (pH ≤5.0). Methamphetamine is metabolized by hepatic metabolism and renal excretion via cytochrome P450 2D6 (CYP2D6). The effects of methamphetamine on the kidneys can be divided into the following sub-groups: vascular effects, non-traumatic rhabdomyolysis and direct nephrotoxicity. Additionally, methamphetamine directly stimulates the release of ET-1, a potent vasoconstrictor. ET-1 stimulates vasoconstriction, inflammation and fibrosis in kidney, thus promoting hypertension, atherosclerosis and chronic kidney disease.

Introduction: Gentamicin sulphate (GS) induces nephrotoxicity by increasing of reactive oxygen species (ROS). Objectives: The aim of this research was to assess the renoprotective effect of dimethyl sulfoxide (DMSO) as an antioxidant agent against GS-induced nephrotoxicity. Materials and Methods: Forty male rats (Sprague-Dawley) were divided equally in to five groups and were treated as follows; group 1; received normal saline and served as normal controls, group 2; received GS (100 mg/kg/d), groups 3; received GS and DMSO (0.5 mL/kg/d), groups 4; received GS and DMSO (1 mL/kg/d), groups 5; received GS and DMSO (2 mL/kg/d). After eight days of treatment, serum was prepared. Paraffin sections (3 µ thickness) were prepared from the left kidneys and stained through periodic acid-Schiff (PAS) method. Serum creatinine and urea were assessed by the kits and serum malondialdehyde (MDA) was assessed by thiobarbituric acid (TBA) test. Volume density of proximal tubules, tubular necrosis, tubular cast and lymphocyte infiltration were evaluated histopathologically. The data were analyzed by Mann-Whitney U test at P< 0.05 by SPSS 12 software. Results: Serum MDA, creatinine, urea, tubular volume density, tubular necrosis, tubular cast and lymphocyte infiltration were ameliorated significantly in groups four and five compared with group two (P<0.05). Conclusion: DMSO improved GS-induced renal toxicity significantly through prevention of lipid peroxidation and inflammation, but could not save kidney functional tests and histological changes at the same level as that of the normal group.

Introduction: Low testosterone level has strongly been correlated with body fat accumulation and abdominal obesity in men. Objectives: This study aimed to evaluate testosterone level in men with and without metabolic syndrome to determine the relationship between testosterone and metabolic syndrome. Patients and Methods: This case-control study was conducted on 172 cases of metabolic syndrome and 172 participants as a control group in Rasoul Akram hospital, Tehran, Iran. Demographic characteristics, fasting blood sugar (FBS), high-density lipoprotein (HDL), low-density lipoprotein (LDL), cholesterol, triglyceride (TG), and testosterone levels were recorded. SPSS version 21.0 and SAS version 9.1 were used for statistical analysis. Level of significance was considered 0.05. Results: The mean age of the two groups were 45.1±9.3 years and 41.5 ±11.2 years, respectively. There was a significant difference in serum testosterone levels between both groups and low testosterone levels were associated with metabolic syndrome (P<0.001). Serum testosterone levels showed a significant negative correlation with age in the metabolic syndrome group (r= -0.16, P=0.02). The relationship between metabolic syndrome and total plasma testosterone level using logistic regression model showed that, by increasing the total plasma testosterone level, the odds ratio for metabolic syndrome was 0.076 (95% CI: 0.027-0.216; P< 0.001). Conclusion: According to the results, low level of testosterone was related to the presence of metabolic syndrome in adult males. Future studies can investigate diagnostic value of testosterone level in this syndrome.

Background and aims: Charcot-Marie-Tooth (CMT) is a common sensory-motor polyneuropathy with a prevalence of 1/2500. It is divided into different subgroups and has various hereditary patterns. Among the different subgroups of CMT, type 1A is the most prevalent form of the disease, which is created due to the duplication of the PMP22 gene. In patients has a deletion in the PMP22 gene, the hereditary neuropathic disease is known to be liable to pressure. The aim of this study was to identify the patients affected by the disease with the new, simple, and fast qPCR method and to investigate the appropriateness of this method in evaluating these types of mutations. Methods: In this analytical-descriptive study (code:IR.SKUMS.REC.1394.152), gene duplication and deletion in the patients were studied using the Excel software. The blood samples of 15 families afflicted with CMT and 49 healthy individuals were collected in EDTA anticoagulant tubes and analyzed. DNA extraction and quantitative real-time PCR method were applied for the PMP22 gene as the target gene and the albumin gene as the internal control gene. Results: Two genes were compared in each patient, and it was found that 46% of the subjects had duplication in the PMP22 gene. Conclusion: The qPCR method is an easy and fast way to detect gene duplication and deletion in CMT patients. It does not require any statistical software and can be performed without needing for parental DNA. In addition, the results of this study are consistent with the results of various studies in some countries of the world where the highest levels of deletion and duplication in PMP22 gene are seen.
Stability Indicating Method to Analyze Benidipine and Chlorthalidone Using HPLC Technique: Establishment, Validation and Application to Tablets
Authors: Jagadeesh Kadali , Annapurna Nowduri
Published: April 2020

Background
: The combination of chlorthalidone and benidipine was used to manage hypertension. The mixture of chlorthalidone and benidipine in tablet dosage form has not been previously determined by any method. A stability indicating HPLC method was developed for the simultaneous determination of benidipine and chlorthalidone in bulk and tablets. Methods: Chromatographic separation was accomplished in a reverse phase system using an isocratic elution with a mobile phase composed of methanol-0.1M dipotassium hydrogen phosphate buffer (40:60, v/v), at 1 ml/min flow rate. The photodiode array (PDA) detector set at 260 nm was used to detect and quantify benidipine and chlorthalidone. Benidipine and chlorthalidone tablet samples were subjected to degradation under acid, neutral, alkali, thermal, photo and oxidative. The proposed method was effectively adapted to quantify benidipine and chlorthalidone in the combined tablet formulation. Results: The elution times for benidipine and chlorthalidone were approximately 4.573 min and 6.422 min, respectively. The method was validated within a concentration range of 2 - 6 μg/ml (R2 = 0.9997) for benidipine and 6.25 - 18.75 μg/ml (R2 = 0.9998) for chlorthalidone. Adequate results were obtained for precision (RSD% = 0.106% for benidipine and RSD% = 0.031% for chlorthalidone) and accuracy (99.95 - 100.25 % mean recovery for benidipine and 99.60 - 99.63% mean recovery for chlorthalidone). Robustness has also been found to be acceptable. During the degradation study, interference was not noticed in the analysis of studied drugs. Conclusion: The findings demonstrated that the method could be useful for determination of the selected drug combination in routine analysis.
