Genetic analysis of human inborn errors of immunity has defined the contribution of specific cell populations and molecular pathways in the host defense against infection. The STAT family of transcription factors orchestrate hematopoietic cell differentiation. Patients with de novo activating mutations of STAT3 present with multiorgan autoimmunity, lymphoproliferation, and recurrent infections. We conducted a detailed characterization of the blood monocyte and dendritic cell (DC) subsets in patients with gain-of-function (GOF) mutations across the gene. We found a selective deficiency in circulating nonclassical CD16+ and intermediate CD16+CD14+ monocytes and a significant increase in the percentage of classical CD14+ monocytes. This suggests a role for STAT3 in the transition of classical CD14+ monocytes into the CD16+ nonclassical subset. Developmentally, ex vivo–isolated STAT3GOF CD14+ monocytes fail to differentiate into CD1a+ monocyte-derived DCs. Moreover, patients with STAT3GOF mutations display reduced circulating CD34+ hematopoietic progenitors and frequency of myeloid DCs. Specifically, we observed a reduction in the CD141+ DC population, with no difference in the frequencies of CD1c+ and plasmacytoid DCs. CD34+ hematopoietic progenitor cells from patients were found to differentiate into CD1c+ DCs, but failed to differentiate into CD141+ DCs indicating an intrinsic role for STAT3 in this process. STAT3GOF-differentiated DCs produced lower amounts of CCL22 than healthy DCs, which could further explain some of the patient pathological phenotypes. Thus, our findings provide evidence that, in humans, STAT3 serves to regulate development and differentiation of nonclassical CD16+ monocytes and a subset of myeloid DCs.

Authors: Sanjeevkumar K , Srija S Sakthi
Published: October 2021

Background:

Elderly patients with mild cognitive impairment (MCI) have decline in executive functions, functional balance, and impact on the ability to perform activities of daily living (ADL). The simulated functional task (FcTSim) program may provide standard benefits on the cognitive function of elderly patients with MCI.

Objective:

This study aimed to find the effectiveness of FcTSim to improve executive functions, functional balance, and ADL in elderly patients with MCI.

Study Design:

A one-arm interventional study.

Method:

An interventional study was conducted on elderly patients with MCI and balance impairment. They were selected for the study on the basis of the Mini-Mental Status Examination score 18–23, Berg Balance Scale (BBS) score of <45 (indicate the greatest risk of falling), and age group between 65–85 years. FcTSim program was given for 4 weeks, a total of 12 sessions (3 sessions per week). Addenbrooke's Cognitive Examination-Revised (ACE-R), BBS, and Canadian Occupational Performance Measure (COPM) scales were used as the outcome measures.

Results:

The mean posttest scores of ACE-R was 11.53 ± 3.62; P < 0.00; 95% confidence interval (CI): 9.52 to 13.54, BBS 8.80 ± 2.36; P < 0.00; 95% CI: 7.49 to 10.11, it shows significant difference and COPM performance 1.00 ± 0.84; P < 0.00; 95% CI: 0.53 to 1.46 satisfaction 1.53 ± 0.91; P < 0.00; 95% CI: 1.02 to 2.04.

Conclusion:

The findings of this study suggest that after 4 weeks encompassing 12 sessions of FcTSim, the elderly patients with MCI showed improvement in their executive functions, functional balance, and ADL such as eating, bathing, dressing, and grooming.
Bidimensional system for space closure treatment of missing lateral incisors
Authors: Greco Mario , Rosa Marco , Rombolà Andrea
Published: October 2021

INTRODUCTION:

Missing lateral incisors represent a common condition that normally requires specific anchorage conditions to be treated with space closure mechanics to protract upper teeth creating a proper occlusal relationship.

CASE PRESENTATION:

Two cases showing Class II malocclusion with missing lateral incisors in developing age are presented, both treated with the same approach of maximum anterior anchorage applied using the Bidimensional Technique system. Long-term follow-up of 10 years is shown.

MANAGEMENT AND OUTCOME:

Bidimensional technique is a modified edgewise technique that uses sliding mechanics for protraction of the posterior segments by placing vertically slotted brackets of different sizes on the anterior (.018” x 0.025”) and posterior teeth (.022” x 0.028”). When a .018” x .022” wire is inserted in the .018” x .025” brackets slot on the incisors, third-order control is created in the incisor segment while the wire is undersized in the rest of the arch. Lateral brackets have been positioned on the canines, while the canine brackets have been positioned on the first premolars respecting a differential bonding height able to produce canine extrusion and first premolars intrusion and proper torque expression. Full Class II molar relationship and Class I substituted canine relationship has been reached in both cases and kept stable in the long-term follow-up (10 years).

DISCUSSION:

The described approach provided anterior anchorage with more simple mechanics expressing the anterior torque with a full engagement concept and adding few auxiliaries (uprighting springs) which do not require compliance.
Evaluation of smile characteristics of skeletal Class III compared to skeletal Class I female adults
Authors: Nouh Abdallah S. , Abdel Majeed H. M. , Nassef Selim Essam Mohamed
Published: October 2021

OBJECTIVE:

Esthetic enhancement plays an important role in orthodontic treatment. This study was conducted on females as most girls have their growth spurt at a younger age than boys do, so their demand to facial esthetics, especially those who have residual growth of mandible producing class III effect, requires full understanding to smile features helping in diagnosis and treatment planning for maximum patient satisfaction.

MATERIALS AND METHODS:

This study was conducted on 30 skeletal Class III and Class I female adults (18–30 years old) who were divided equally into two groups comprising 15 each. Two frontal digital photographs were taken for each subject, one at rest and the other in the posed smile position. Photographs were taken for each subject in the natural head position by a Canon EOS 1200 D camera set on a tripod at a distance of 1.5 m. The incisogingival height of the right maxillary central incisor was clinically measured using a vernier caliper to the nearest 0.1 mm. Photographs were uploaded on Photoshop software for standardization and then uploaded on the Digital Smile Design software (DSD) where the actual incisogingival height of the central incisor was used for automatic calibration. Esthetic components at rest and on smiling were measured for both groups; all linear variables were measured to the nearest 0.1 mm.

RESULTS:

Class III females tended to have wider smile widths, less gingival display, longer chin heights, shorter lower vertical dimensions, and a higher percentage of nonconsonant and flat smile arcs than Class I subjects.

CONCLUSIONS:

The components of the smile should be considered as a guide to help in planning and designing the mechanics during comprehensive orthodontic treatment.

PurposeThe clinical significance of body mass index (BMI) on long-term outcomes has not been extensively investigated in Asian patients with colorectal cancer (CRC). This study aims to describe the association between BMI and survival, plus providing BMI cut-off value for predicting prognosis in CRC patients.Materials and MethodsA total of 1,182 patients who had undergone surgery for stage I-III CRC from June 2004 to February 2014 were included. BMI was categorized into four groups based on the recommendation for Asian ethnicity. The optimal BMI cut-off value was determined to maximize overall survival (OS) difference. ResultsIn multivariable analysis, underweight BMI was significantly associated with poor OS (hazard ratio [HR], 2.38; 95% confidence interval [CI], 1.55 to 3.71; p < 0.001) and obese BMI was associated with better OS (HR, 0.72; 95% CI, 0.53 to 0.97; p=0.036) compared with the normal BMI. Overweight and obese BMI were associated with better recurrence-free survival (HR, 0.64; 95% CI, 0.42 to 0.99; p=0.046 and HR, 0.58; 95% CI, 0.38 to 0.89; p=0.014, respectively) compared with the normal BMI group. BMI cutoff value was 20.44 kg/m2. Adding the BMI cutoff value to cancer staging could increase discriminatory performance in terms of integrated area under the curve and Harrell’s concordance index. ConclusionCompared to normal BMI, underweight BMI was associated with poor survival whereas obese BMI was associated with better survival. BMI cut-off value of 20.44 kg/m2 is a useful discriminator in Asian patients with CRC.
Subgroups of right-angled Coxeter groups via Stallings-like techniques
Authors: Dani Pallavi , Levcovitz Ivan
Published: October 2021

We associate cube complexes called completions to each subgroup of a right-angled Coxeter group (RACG). A completion characterizes many properties of the subgroup such as whether it is quasiconvex, normal, finite-index or torsion-free.We use completions to show that reflection subgroups are quasiconvex, as are one-ended Coxeter subgroups of a 2-dimensional RACG. We provide an algorithm that determines whether a given one-ended, 2-dimensional RACG is isomorphic to some finite-index subgroup of another given RACG. In addition, we answer several algorithmic questions regarding quasiconvex subgroups. Finally, we give a new proof of Haglund’s result that quasiconvex subgroups of RACGs are separable.

The potential cytotoxic effects of urban particle matter on olfaction
Authors: Kim B.-Y. , Park J.Y. , Cho K.J. , Bae J.H.
Published: October 2021

Background: Urban particulate matter (UPM) in ambient air is implicated in a variety of human health issues worldwide, however, few studies exist on the effect of UPM on the olfactory system. This study aimed to identify the factors affecting the destruction of the olfactory system in a mouse model following UPM exposure. Methods: Mice were divided into: control and four UPM-exposed groups (200 µg UPM at 1 and 2 weeks, and 400 µg UPM at 1 and 2 weeks [standard reference material 1649b; average particle diameter 10.5 μm]). The olfactory neuroepithelium was harvested for histologic examination, gene ontology, quantitative real-time polymerase chain reaction, and western blotting. Results: Compared to the control group, olfactory marker protein, Olfr1507, ADCY3, and GNAL mRNA levels were lower, and S-100, CNPase, NGFRAP1, BDNF, and TACR3 mRNA levels were higher in the olfactory neuroepithelium of the UPM groups. Moderately positive correlation was present between the 1- and 2-week groups. After analyzing the 200 and 400 UPM groups separately, the strength of the association between the 200 UPM 1- and 2-week groups was moderately positive. No differences was present in the neuroepithelial inflammatory marker levels between the UPM and control groups. Conclusions: UPM could have cytotoxic effects on the olfactory epithelium. The exposure time and particular concentration of UPM exposure could affect the degree of destruction of the olfactory neuroepithelium. The olfactory regeneration mechanism could be related to the neurotrophic factors, olfactory ensheathing cell stimulation, and trigeminal nerve support.

Published: October 2021

The shell height-body weight relationship of the black clam Chionista fluctifraga cultivated in the intertidal of the southeastern Gulf of California, was evaluated for the first time, to improve the knowledge in determining its harvesting time. Clam seeds (n=900,000; 6.1±1.9 mm) were produced in the laboratory. The culture was divided into pre-fattening in racks on the bottom (2 months) and fattening directly in the bottom (16 months) from May 2018 to October 2019. Each month, 60 (n=1080) clams were randomly selected to stablish the morphometric relationship between shell height (SH) and body weight (BW). The growth rate (mm/d and g/d) was recorded. The SH-BW Interaction in both cultivation phases showed positive allometry. SH in prefattening and fattening registered a growth rate of 0.072 and 0.058 mm/d, respectively. In fattening, the interaction BW-SH displayed a high coefficient of determination (R2=0.99). A final survival rate of 90% was obtained. The results yielded the equations that describe the relative growth of C. fluctifraga for the fattening stage. A harvesting time after 10 months of fattening in the intertidal zone is stablished to reach the commercial size (35 mm, SH).

Authors: Dilmi Ammar , Refes Wahid , Meknachi Abdellah
Published: October 2021

A 62-d trial was conducted to evaluate the effects of different C/N ratios on water quality, growth performance, digestives activity, and antioxidant indicators of tilapia fingerlings in BFT systems. Three biofloc treatments (added molasses) with a C/N ratio of 14 (BFT14), 17 (BFT17), and 20 (BFT20) were tested against control in clear-water, each treatment in triplicate. Four hundred twenty tilapias (24.2±0.1 g) were distributed on 12 tanks of 350 L. The dynamics of water quality parameters showed a shift from a predominantly autotrophic to a predominantly heterotrophic biofloc with an increase in the C/N ratio from 14 to 20. The growth and Feed conversion of tilapia were not significantly different between the control, BFT14, and BFT17 groups. A low weight gain and high FCR were found in the BFT20 treatment (0.61±0.07 and 1.11±0.12 g/d) compared to the control (0.84±0.05 and 1±0.07 g/d). Activities of proteases and alpha-amylase in the liver and digestive tract were similar in all treatments. As a measure of stress, CAT and SOD activities did not differ significantly among the four groups. Overall, it was possible to reduce the C/N ratio to14, without negatively affecting the biofloc development, growth performance, and physiological parameters of juvenile tilapia.

Published: October 2021

Edwardsiella tarda, the causative agent of ascites disease, is a major fish pathogen and has caused significant economic losses in aquaculture. To decipher the immune response process challenged by E. tarda in yellow catfish (Pelteobagrus fulvidraco), the transcriptomic profiles of the spleens infected with bacteria at 6 h, 24 h, and 72 h were obtained using the Illumina sequencing platform. After de novo assembly, a total of 158,124 unigenes were detected. To further investigate the immune-related DEGs, gene ontology (GO) enrichment and KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway analysis were performed. Immune pathways about antigen processing and presentation pathway, complement and coagulation cascades pathway, and apoptosis pathway were combined to discussed in this study. Additionally, 10 immune-related DEGs in these three immune pathways were randomly selected for expression verification by quantitative Real-time PCR (qRT-PCR). The data generated in this study provides a valuable resource for further immune response research and offers efficient strategies against E. tarda infection in yellow catfish.
Lining Wear Measurements using a Coordinate Measurement Machine
Authors: Learman Cara , Campbell Kevin
Published: October 2021

Accurate measurements of brake friction materials are critical to understanding brake behaviors during testing. Current methods typically utilize a hand gauge (or a machine, in some cases) to sample various discrete points on the brake lining. This approach limits measurements to planar wear characteristics, taper and thickness, and excludes more complex measurements such as cupping. The limited number of points means that a single errant point measurement or the choice of point locations can have a large impact on the reported wear measurement.

This paper will describe a method for utilizing a Coordinate Measurement Machine (CMM) fitted with a laser line scanning tool to generate a point cloud of data that can then be compared to an earlier measurement of the same piece or to a math model. This method produces thousands of data points which allows for more accurate volumetric wear calculations and color maps of the entire friction face. A gage R&R for this method is presented along with some of the challenges involved in fixturing and aligning brakes pads for analysis.

Objective: We assessed the level of community acceptance of COVID-19, identified and implemented strategies to demystifying stigma in a severely affected population in Tema.Design and Setting: We conducted a cross-sectional study to assess stigma among the Tema community, then identified and implemented interventions to demystify COVID-19 stigma. We interviewed positive cases, their contacts, contact tracers, case management team members, and community members who shared their first hand experiences and knowledge on the current pandemic.Intervention: Based on the information received, we came up with ways of reducing stigma and implemented them in their community.Main Outcome: Stigma demystifiedResults: Cases and contacts reported being avoided, discriminated against, insulted or had derogatory words used on them by family, friends, work colleagues or the community. Cases and their contacts stated that stigmatisation was fueled by the presence of COVID -19 branded vehicles and security officials at their homes or workplaces. Stakeholder engagement, education and extensive sensitisation of community members were implemented to reduce stigma.Conclusion: We observed deeply entrenched stigma to COVID - 19 positive patients and their contacts in the community. Health care response mechanisms such as the presence of security personnel with contact tracers and case managers and the use of COVID -19 branded vehicles fueled stigma. A multifaceted approach through the engagement of key stakeholders, training of health workers and extensive education and community sensitisation was essential in reducing stigma.

Malaria-endemic areas of the world are noted for high morbidity and mortality from malaria. Also noted in these areas is the majority of persons in the population having acquired malaria immunity. Though this acquired malaria immunity does not prevent infection, it resists the multiplication of Plasmodium parasites, restricting disease to merely uncomplicated cases or asymptomatic infections. Does this acquired malaria immunity in endemic areas protect against other diseases, especially outbreak diseases like COVID-19? Does malaria activation of innate immunity resulting in trained or tolerance immunity contribute to protection against COVID-19? In an attempt to answer these questions, this review highlights the components of malaria and viral immunity and explores possible links with immunity against COVID-19. With malaria-endemic areas of the world having a fair share of cases of COVID-19, it is important to direct research in this area to evaluate and harness any benefits of acquired malaria immunity to help mitigate the effects of COVID-19 and any possible future outbreaks.

Published: October 2021

This article deals with the study of some qualitative properties of a cubic autocatalator chemical reaction model. Particularly, we obtain a dynamically consistent cubic autocatalator discrete-time model by applying a nonstandard difference scheme. Analysis of the existence of equilibria and their stability is carried out. It is proved that a continuous system undergoes the Hopf bifurcation at its interior equilibrium, whereas the discrete-time version undergoes Neimark-Sacker bifurcation at its interior fixed point. Moreover, numerical simulation is provided to strengthen our theoretical discussion.

Both round-off and truncation error analyses are given besides the convergence analysis. Coupled Lane Emden boundary value problem in Catalytic Diffusion Reactions is investigated by using presented method. The obtained results are compared with the existing methods in the literature and it is observed that the proposed method gives more reliable results than the others.
Territorio usado e circuito superior marginal: Equipamentos médicos em campinas, Ribeirão Preto e São José do Rio Preto (SP)
Authors: David Virna Carvalho
Published: October 2021

A tecnociência, a informação e as finanças são variáveis determinantes da globalização e isso se releva também para a saúde. Os avanços tecnológicos no campo da medicina e a recente sofisticação dos serviços de diagnóstico e tratamento revelam a difusão do meio técnico científico e informacional (Santos, 1994), ao mesmo tempo em que reforçam antigas concentrações da produção de bens e de serviços de saúde. No Brasil, o impacto seletivo das modernizações criou uma produtividade geográfica em algumas cidades do estado de São Paulo, como Campinas, Ribeirão Preto e São José do Rio Preto. É, portanto, no contexto da urbanização recente que podemos observar novas formas de trabalho ligadas aos equipamentos médicos que emergem dentro do processo de substituição de umadivisão do trabalho por outra mais moderna. Uma diversidade de agentes com diferentes níveis de capital, tecnologia e organização passa a dinamizar uma economia urbana complexa ligada a rede de cidades do país, dando forma aos circuitos da economia urbana (Santos, 1979). O território usado para produzir e consumir saúde mostrou como a tecnificação da medicina moderna tem beneficiado um processo acelerado de renovação técnica e normativa da produção nacional de aparelhos médicos. O circuito superior marginal desses equipamentos emergente nessas três cidades foi capaz de nos mostrar novos mecanismos de oligopolização da economia urbana e de uso do território

 

Technoscience, information and finance are determining variables of globalization, and this is also relevant to health. Technological advances in the medical field and the recent sophistication of diagnostic and treatment services reveal the diffusion of the technical scientific and informational environment (Santos, 1994), while at the same time reinforcing old concentrations of the production of goods and health services. In Brazil, the selective impact of modernizations has created a geographical productivity in some cities of the state of São Paulo, such as Campinas, Ribeirão Preto and São José do Rio Preto. It is, therefore, in the context of recent urbanization that we can observe new forms of work linked to medical equipment emerging within the process of replacing one division of labor with a more modern one. A diversity of agents with different levels of capital, technology and organization start to dynamize a complex urban economy linked to the network of cities in the country,shaping the circuits of the urban economy (Santos, 1979). The territory used to produce and consume health showed how the technification of modern medicine has benefited an accelerated process of technical and normative renovation of the national production of medical equipment. The marginal upper circuit of these equipment emerging in these three cities was able to show us new mechanisms of oligopolization of the urban economy and of the use of territory.

Se propone una reorientación de la política de atención primaria en salud para los organismos de previsión social públicos. El cambio consiste en impulsar medidas que conduzcan a transformar las actividades que actualmente en materia de salud ejecutan esas organizaciones, las cuales son mayoritariamente de tipo curativo y convertirlas en acciones y orientaciones de carácter preventivos, mediante la aplicación de innovadores programas de promoción, prevención y control de las enfermedades no transmisibles (ENT).

En razón de lo expuesto, como eje de este proceso se presenta la implementación del Sistema Preventivo de Enfermedades no Transmisibles (SPENT), con una visión integrada de las áreas prioritarias de prevención, de acuerdo con los indicadores de morbilidad y buscando como resultado la vigilancia efectiva y el control de los factores de riesgo, que conducirían a una reducción de la prevalencia de las ENT. Para ello, es necesario crear conciencia en los sistemas de salud pública de que todo lo que se invierta en la prevención de la salud es beneficioso para las personas y para la sociedad. “Prevenir es mejor que curar”.

 

A reorientation of primary health care policy is proposed for public social welfare organizations. The change is to promote measures that lead to transform the health activities currently implemented by these organizations, which are mostly curative, and convert it into actions and orientations mainly preventive, through the implementation of innovative programs for the promotion, prevention and control of noncommunicable diseases (NCD), 

On the basis of the above, as the central point of this process is presented the implementation of the Preventive System of Noncommunicable Diseases (SPENT), with an integrated vision in priority prevention areas, in accordance with morbidity indicators and looking as an effective surveillance and control of risk factors, which would lead to a reduction in the prevalence of NCD. To do this, it is necessary to raise awareness among public health systems that everything invested in health prevention is beneficial for individuals and society."To Prevent is better than cure"

In the present study, the algae Undaria pinnatífida has been investigated as a biological adsorbent for the elimination of pollutants from surface waters, specifically heavy metals. Operational parameters were optimized in batch phytoremediation experiments. Adsorption equilibrium isotherm models were also investigated and adsorption kinetics were evaluated. Maximum adsorption capacities were observed at 0.008 mg / L at 0.064 mg / L of Cd and for the second sample the adsorption capacity was calculated at 0.007 mg / L at 0.055 mg / L of Cd both in a time of 24 hours, together With removal efficiencies, they reached 72% and 92.7% for the remediation of the Rio Grande water, respectively. These results are important in the development of zero-cost, algal-based pollutant removal technology in water treatment.

La vaguedad y la precisión: Ejercicios de elasticidad lingüística
Authors: Jiménez Santiago U. Sánchez
Published: October 2021

La vaguedad es una propiedad inherente de las lenguas naturales y, también, una estrategia discursiva eficaz. En este trabajo se presta atención a los rasgos de la vaguedad lingüística, a los motivos que justifican su existencia, a los tipos de vaguedad y a la relación que se establece con otros procesos semánticos como la polisemia, la homonimia o la modalidad epistémica. La vaguedad intencional (la que persigue un fin comunicativo) ha de enmarcarse dentro del contínuum precisión-imprecisión. En el ámbito de la vaguedad intencional ha de distinguirse una vaguedad pragmática (generada por el contexto) y otra vaguedad lingüística, consistente en el empleo de elementos lingüísticos que estrechan el margen de precisión o amplían el espectro de la vaguedad. La posibilidad de que el emisor pueda intervenir en el grado de precisión o imprecisión de una expresión lingüística pone de manifiesto la elasticidad del idioma.

Vagueness is an inherent property of natural languages ​​and also an effective discursive strategy. In this work attention to features of linguistic vagueness, the reasons for their existence, the types of vagueness and the relationship established with other semantic processes such as polysemy, homonyms or epistemic modality is provided. The intentional vagueness (which pursues a communicative purpose) must fit within the continuum of precision-vagueness. In the field of intentional vagueness we have to distinguish a pragmatic vagueness (generated by the context) and other linguistic vagueness, consisting of the use of linguistic elements that narrow the margin of precision or broaden the spectrum of vagueness. The possibility that the speaker may select the degree of accuracy or inaccuracy of a linguistic expression shows the elasticity of language.

Background: Since the first report of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), widely known as COVID-19, in late December 2019, it has spread worldwide. The eventual return of new normal has started to happen in most countries where the COVID-19 curve has flattened, and Assisted reproduction technology (ART) services are eventually resuming. Well-organized ART (embryology/andrology) laboratories safeguard the wellbeing of all staff, patients, and their gametes/embryos.

Main body: A well-organized pandemic management plan must be implemented in anticipation of possible subsequent COVID-19 waves. Apart from local and national guidelines, some mandatory changes need to be taken into considerations that will allow us to overcome the fear of this deadly pandemic, work smoothly and stop any possible transmission without comprising the quality control for successful treatment. These mandatory changes include conserving different supplies, reducing manpower needs, and various protective measures for non-clinical and clinical staff, patients, and gametes/embryos.

Conclusion: The current pandemic of COVID-19 suggests a well-organized action-oriented emergency plan to assure the wellbeing of all stakeholders.

The term organization has two general meanings. First, the organization is defined as an  institution  or functional  group, for  example:  a  company, a  school, an  association, government agencies. Second, referring  to the organizing  process, namely how work is organized and allocated among members, so that the goals of  the organization  can be effectively achieved. While  the organization  itself is defined as  a group of people with  a system of cooperation to achieve common goals. There are two help words contained in the Qur'an to study this organization. The word is Shaff and the Ummah. The word shaff inspires the concept that organizations must have members, consisting of people, in a place, there is order, purpose, leader, delegation of  authority  and  responsibility,  and  there is sincere intention and struggle in the way of God. The conclusion that the organizational structure at the time of the Messenger of Allāh if reached the khalifah and is now almost the same, only different ideologies. Formerly using the law of  Allah  SWT, based  on the Qur'an  and hadith,  while  at this time we use  the Pancasila ideology, using two sources of law: the civil / criminal law of the Dutch heritage and the compilation of Islamic law. At the time of Islam, financial instruments focus on the zakat and tax sectors, while for our government today we use more tax financial instruments. Organizations in the view of Islam are not merely a container, but rather emphasize how a job is done neatly. The organization places more emphasis on regulating work mechanisms. every person who accepts the leadership task that the highest leadership belongs to Allah, for that the leadership given and carried out must always refer to the basic concepts bui lt in Islam. The thing that must be realized that in a good organization must also be accompanied by Islamic values including sincerity, togetherness and sacrifice.
