Treatment of sharp mandibular alveolar process with hybrid prosthesis
Authors: Sukaedi Sukaedi , Djulaeha Eha
Published: August 2017

Background: Losing posterior teeth for a long time would occasionally lead to the sharpening of alveolar process. The removable partial denture usually have problems when used during mastication, because of the pressure on the mucosa under the alveolar ridge. Purpose: The purpose of this case report was to manage patients with sharp mandibular alveolar process by wearing hybrid prosthesis with extra coronal precision attachment retention and soft liner on the surface base beneath the removable partial denture. Case: A 76 years old woman visited the Prosthodontic Clinic Faculty of Dentistry Airlangga University. The patient had a long span bridge on the upper jaw and a free end acrylic removable partial denture on the lower jaw. She was having problems with mastication. The patient did not wear her lower denture because of the discomfort with it during mastication. Hence, she would like to replace it with a new removable partial denture. Case management: The patient was treated by wearing a hybrid prosthesis with extra coronal precision attachment on the lower jaw. Soft liner was applied on the surface of the removable partial denture. Hybrid prosthesis is a complex denture consisting of removable partial denture and fixed bridge. Conclusion: It concluded that after restoration, the patient had no problems with sharp alveolar process with her new denture, and she was able to masticate well.Latar belakang: Kehilangan geligi posterior dapat menimbulkan processus alveolaris tajam. Gigi tiruan sebagian lepasan mempunyai masalah selama pengunyahan karena adanya tekanan di mukosa di bawah alveolar ridge. Tujuan: Tujuan laporan kasus ini adalah untuk menjelaskan cara menangani pasien yang mempunyai prosesus alveolaris yang tajam di rahang bawah dengan dibuatkan protesis hybrid dengan daya tahan extra coronal precision attachment dan soft liner di permukaan bawah basis gigi tiruan sebagian lepasan. Kasus: Pasien wanita berumur 76 tahun datang di klinik Prostodosia Fakultas Kedokteran Gigi Universitas Airlangga. Pasien memakai gigi tiruan lekat rentang panjang di rahang atas dan gigi tiruan sebagian lepasan akrilik free end di rahang bawah, pasien mengalami masalah waktu mengunyah. Pasien tidak memakai gigitiruan lepasan rahang bawahnya karena tidak nyaman dipakai, dan pasien menginginkan pembuatan gigi tiruan lepasan rahang bawah yang baru. Tatalaksana kasus: Pada pasien ini dilakukan pembuatan Hybrid Prosthesis dengan daya tahan berupa extra coronal attachment di rahang bawah dan penggunaan bahan pelapis lunak yang diaplikasikan pada basis gigi tiruan lepasan nya. Hybrid prosthesis adalah gigi tiruan himpunan yang terdiri dari gigi tiruan lepasan dan gigi tiruan lekat. Kesimpulan: Hasil perawatan menunjukkan setelah mengganti gigi tiruan dengan gigi tiruan sebagian lepasan yang baru, pasien tidak mempunyai masalah dengan gigi tiruan yang baru akibat processus alveolaris yang tajam dan pasien dapat mengunyah dengan baik.
SuperPath: The Direct Superior Portal-Assisted Total Hip Approach
Authors: Chow James
Published: August 2017

The supercapsular percutaneously assisted total hip (SuperPath; MicroPort) approach is a direct superior portal-assisted approach for total hip arthroplasty (THA) that utilizes the interval between the gluteus minimus and the piriformis to access the hip capsule. The technique was developed to promote early mobilization, greater range of motion, and improved pain control. The major steps of this procedure are as follows:

Step 1: Patient positioning. The patient is in the standard lateral decubitus position with the involved leg in the “home position,” that is, 45° to 60° of flexion, 20° to 30° of internal rotation, and slight adduction by elevating the foot on a padded Mayo stand.

Step 2: Surgical exposure. A skin incision is made from the tip of the greater trochanter 6 to 8 cm proximally in line with the femur in the home position, the gluteus maximus muscle is split by blunt dissection in line with the fibers, and the gluteus medius and minimus are retracted anteriorly and the piriformis tendon is retracted posteriorly to access to the capsule without dissecting any muscles.

Step 3: Capsular incision. The capsule is incised along the path of the skin incision from the saddle of the femoral neck to 1 cm proximal to the acetabular rim.

Step 4: Femoral preparation. A channel is created in the superior aspect of the femoral neck from the femoral canal to the center of the femoral head, using reamers, a round osteotome, and a curet.

Step 5: Femoral broaching. Sequential femoral broaches are then used to complete the preparation and size the proximal femoral canal while the head and neck remain intact.

Step 6: Neck resection. The femoral neck osteotomy is performed level with the broach neck, and Schanz pins are used to rupture the ligamentum teres and remove the femoral head.

Step 7: Acetabular preparation and placement. Acetabular preparation and cup impaction are done through a portal without needing release of the iliotibial band or remaining external rotators. A sharp Romanelli self-retaining retractor (Innomed) and modified Zelpi self-retaining retractor (Life Instruments) are used.

Step 8: Trial reduction. Trial reduction is completed using a bone hook and a T-handle to gently manipulate the femur.

Step 9: Final implant assembly. Liner impaction is completed through the portal, and the remaining components are implanted.

Step 10: Closure. Closure is limited to the capsule, fat, and skin, since no muscles are dissected during this procedure.

A recent multicenter study describing nearly 500 SuperPath THAs noted a 30-day all-cause readmission rate of 2.3% and a transfusion rate of 3.3%5. The average length of stay was 1.6 days, with 91% of patients discharged home; 4.1%, to skilled nursing facilities; 3.8%, to home care; and 0.6%, to inpatient physical therapy facilities6.

Published: August 2017

The use of amaranth (Amaranthus spp.) in the food and dietary supplements industry is increasing. The aim of this work is to promote the Mediterranean area as a production hot spot, by using multivariate statistical analyses on data obtained in two‐year trials and relating to morphological, productive, and qualitative traits and antioxidant activity of 20 accessions of five amaranth species (A. caudatus L., A. cruentus L., A. hybridus L., A. hypochondriacus × hybridus L., A. hypochondriacus L.). Amaranthus cruentus accessions (Mexicane and New Mexico) were stable and highly productive (>2.7 t seeds ha−1), while Kinnaury Dhankar accession showed the highest protein percentage (17%). Amaranthus hypochondriacus (Orange Giant and Burgundy) possessed the highest oil percentage (always above 5.7%). A high amount in linoleic, cis‐oleic, and palmitic acids, and an interesting saturated/unsaturated acids ratio ranging from 0.26 (A. hybridus) to 0.32 (A. hypochondriacus) were detected. The unsaponifiable fraction revealed the abundance of squalene in all species, while total tocopherol concentrations were lower than expected.

Published: August 2017

To diversify the sources of the high‐oleate trait in peanut (Arachis hypogaea L.), the broad‐based interspecific derivative with inherent resistance to major foliar diseases, GPBD‐4, was subjected to chemical (ethyl methanesulfonate) and physical (γ rays) mutagenesis, resulting in significant variation in fatty acid profile of mutant progenies as tested by gas chromatography in advanced (M4) generations. From these mutant progenies, two stable high‐oleic (>70%) mutant lines, GM 4‐3 and GM 6‐1, were chosen for molecular characterization of ahFAD2B by cloning and sequencing. We report here the identification of two novel mutations (1085A‐G and 1111G‐A) in oleoyl‐PC desaturase (ahFAD2B) of high‐oleic mutant line GM 6‐1 and the latter single transition 1111G‐A in another high‐oleic mutant line GM 4‐3. The deduced amino acid sequence comparison of the parental genotype, GPBD‐4, with normal‐oleic (∼50%) and high‐oleic (>70%) mutant lines indicated the common change from glycine to serine at 372 from start codon due to the common single‐nucleotide polymorphism (SNP, 1111G‐A) observed in both the high‐oleic mutant lines. Another amino acid change from glutamate to glycine was also found in the mutant line GM 6‐1 because of the additional SNP it had at 1085A‐G in the coding region of ahFAD2B. These novel mutations identified in the new high‐oleic mutant lines could be used for marker‐assisted selection for the high‐oleate trait, and these foliar disease‐resistant, high‐oleic mutant lines could serve as additional valuable genetic resources for oil quality improvement in future peanut breeding programs.
Idempotents in intensional type theory
Authors: Shulman Michael
Published: August 2017

We study idempotents in intensional Martin-L\"of type theory, and in
particular the question of when and whether they split. We show that in the
presence of propositional truncation and Voevodsky's univalence axiom, there
exist idempotents that do not split; thus in plain MLTT not all idempotents can
be proven to split. On the other hand, assuming only function extensionality,
an idempotent can be split if and only if its witness of idempotency satisfies
one extra coherence condition. Both proofs are inspired by parallel results of
Lurie in higher category theory, showing that ideas from higher category theory
and homotopy theory can have applications even in ordinary MLTT.
Finally, we show that although the witness of idempotency can be recovered
from a splitting, the one extra coherence condition cannot in general; and we
construct "the type of fully coherent idempotents", by splitting an idempotent
on the type of partially coherent ones. Our results have been formally verified
in the proof assistant Coq.
Some theorems on passing from local to global presence of properties of functions
Authors: Skordev Dimiter
Published: August 2017

When given a class of functions and a finite collection of sets, one might be
interested whether the class in question contains any function whose domain is
a subset of the union of the sets of the given collection and whose
restrictions to all of them belong to this class. The collections with the
formulated property are said to be strongly join permitting for the given class
(the notion of join permitting collection is defined in the same way, but
without the words "a subset of"). Three theorems concerning certain instances
of the problem are proved. A necessary and sufficient condition for being
strongly join permitting is given for the case when, for some $n$, the class
consists of the potentially partial recursive functions of $n$ variables, and
the collection consists of sets of $n$-tuples of natural numbers. The second
theorem gives a sufficient condition for the case when the class consists of
the continuous partial functions between two given topological spaces, and the
collection consists of subsets of the first of them (the condition is also
necessary under a weak assumption on the second one). The third theorem is of a
similar character but, instead of continuity, it concerns computability in the
spirit of the one in effective topological spaces.
Discovering, quantifying, and displaying attacks
Authors: Vigo Roberto , Nielson Flemming , Nielson Hanne Riis
Published: August 2017

In the design of software and cyber-physical systems, security is often
perceived as a qualitative need, but can only be attained quantitatively.
Especially when distributed components are involved, it is hard to predict and
confront all possible attacks. A main challenge in the development of complex
systems is therefore to discover attacks, quantify them to comprehend their
likelihood, and communicate them to non-experts for facilitating the decision
process. To address this three-sided challenge we propose a protection analysis
over the Quality Calculus that (i) computes all the sets of data required by an
attacker to reach a given location in a system, (ii) determines the cheapest
set of such attacks for a given notion of cost, and (iii) derives an attack
tree that displays the attacks graphically. The protection analysis is first
developed in a qualitative setting, and then extended to quantitative settings
following an approach applicable to a great many contexts. The quantitative
formulation is implemented as an optimisation problem encoded into
Satisfiability Modulo Theories, allowing us to deal with complex cost
structures. The usefulness of the framework is demonstrated on a national-scale
authentication system, studied through a Java implementation of the framework.

Authors: Pawar Satish Ambadas
Published: August 2017

The incidence of diseases like angina pectoris, myocardial infarction, hypertension and cerebrovascular is increasing nowadays. The high blood lipid level is found to be the main cause of atherosclerosis. Present study is undertaken with the aim to evaluate the effect of physical training on BMI, Waist-hip ratio and lipid profile. Our research is focussed to study the Effect of Physical Training on Serum Lipids in physically trained adults and sedentary adults. To compare lipid profile between physically trained adult and sedentary adult. The study was conducted on 50 male physically trained adults and 50 male sedentary adults in the age group between 30-40 years. Following parameters were evaluated: Total cholesterol, Triglycerides, HDL, LDL and VLDL. There is statistically highly significant decrease in BMI, Waist-hip ratio, total cholesterol, triglycerides, LDL- C, VLDL- C, and highly significant increase in HDL- C in physically trained adults as compared to sedentary adults. From the results, it is concluded that combination of aerobic exercise and games causes highly significant decrease in total cholesterol, TG, LDL- C, VLDL-C and increase in HDL-C. Thus, combination of aerobic exercise and games is more beneficial instead of only aerobic exercise and hence should be recommended.

Published: August 2017

This study was undertaken during the favourable breeding season of the year 2016-17 on healthy mature Gir cattle and Surti buffalo bulls, three each, at Sperm Station of the College. The ejaculates (9/bull, total 54) collected in the morning using artificial vagina were evaluated for routine seminal attributes, including acrosomal and plasma membrane integrity. The mean values of ejaculate volume, sperm concentration, mass activity (0-5 score), individual sperm motility, live sperm, abnormal sperm, intact acrosome and HOST reactive sperms observed in fresh semen of Gir cattle and Surti buffalo bulls were 6.20±0.42 and 3.34±0.23 ml (P less than 0.01), 1169.44±61.71 and 846.30±54.82 million (P less than 0.01), 3.44±0.09 and 3.42±0.08, 76.53±0.53 and 80.76±0.39 % (P less than 0.05), 81.00±1.32 and 84.73±0.78 % (P less than 0.05), 6.00±0.37 and 5.81±0.40 %, 95.59±0.35 and 95.54±0.25 % as well as 80.30±1.90 and 84.58±0.88 % (P less than 0.05), respectively. The variation between cattle and buffalo semen was significant for most of these traits. The variations between bulls within breed were however not significant. Significant correlations were observed only between mass activity and initial motility (0.62), and live and abnormal sperm (-0.41) in Gir bulls, and for ejaculate volume with sperm concentration (-0.56) and abnormal sperm (0.45), and between live and HOS reactive sperms (0.48) in Surti bulls.

Este trabalho tem como objetivo ampliar a compreensão dos significados e finalidades dessas doenças na vida das pessoas. Tal questão diz respeito à manifestação simbólica do conflito inconsciente através do sintoma, levando-se em consideração que este precisa da ação do psíquico e do somático, isto é, do emocional e do físico. Vivências ou conteúdos com cunho emocional significativo que não são verbalizadas ou liberadas de outra forma visível podem se manifestar no corpo, revelando assim o conteúdo negado, reprimido e inconsciente. O coração, órgão essencial do corpo humano, bem como as emoções nele projetadas ou por ele expressas carregam importante simbologia. Seria um equívoco tratá-lo tão somente como um órgão, separando soma e psique, corpo e emoção. Julgamos de suma importância olhar o sintoma de modo diferenciado, analisando o que este quer expressar, ao invés de simplesmente optar pela medicalização da questão. É premente compreender o ser humano integralmente, com toda sua complexidade: um ser biológico, psíquico, emocional e espiritual.

Background and objectives

Several drugs used in CKD can prolong electrocardiographic conduction. We examined the use of electrocardiogram QT-prolonging medications in predialysis CKD and their association with QT duration.

Design, setting, participants, & measurements

In total, 3252 Chronic Renal Insufficiency Cohort participants with at least one study electrocardiogram between 2003 and 2011 were included. QT-prolonging medications used in 100 or more visits (n=16,451 visits) along with diuretics and proton pump inhibitors, given their potential for electrolyte disturbances, were examined for QT interval prolongation.

Results

Mean QT interval corrected for heart rate was at 414±21 (±SD) milliseconds and prolonged (≥450 milliseconds) in 4.6% of electrocardiograms. QT interval corrected for heart rate was inversely related to serum potassium and calcium. Medications classified as QT prolonging were taken at 76% of visits, with two or more of these taken at 33% of visits. Of 30 medications examined, eight were associated with statistically significant QT interval corrected for heart rate prolongation after adjustment for comorbidities, potassium, and calcium, including amiodarone (+10±2 milliseconds), metolazone (+7±2 milliseconds), fluoxetine (+4±1 milliseconds), citalopram (+4±1 milliseconds), hydroxyzine (+4±1 milliseconds), escitalopram (+3±2 milliseconds), venlafaxine (+3±1 milliseconds), and furosemide (+3±0 milliseconds). Potassium-depleting diuretics were associated with minimal decrements in potassium (between 0.1 and 0.3 mEq/L) and smaller changes in calcium. Diuretics associated with a change in QT interval corrected for heart rate before adjustment for potassium and calcium were metolazone (+8±3 milliseconds), furosemide (+4±1 milliseconds), and spironolactone (−3±3 milliseconds). Most of the QT prolongation associated with metolazone and furosemide, but not spironolactone, remained after adjustment for potassium and calcium. Proton pump inhibitors were not associated with QT prolongation.

Conclusions

Use of medications associated with QT prolongation is common in CKD; the safety implications of these findings should be considered in these high-risk patients.

Encontro com meninos Infâncias como potência
Authors: Louzada Virgínia , Ribeiro Andréa
Published: August 2017

Este artigo propõe uma reflexão sobre a potência infantil, a partir da observação de duas crianças consideradas especiais numa creche escola situada à Zona Norte do Rio de Janeiro. O encontro com elas permitiu às autoras do texto desconstruir conceitos preestabelecidos sobre infância, aprendizagem, educação e escola. A discussão privilegia a educação inclusiva e a avaliação. O artigo defende a necessidade de se enxergar as crianças de modo afirmativo, por sua potência, e a importância da reflexão constante dos educadores sobre a prática pedagógica.
O lugar das Ciências Humanas na “reforma” do ensino médio
Authors: Simões Willian
Published: August 2017

O presente texto objetiva refletir e fomentar o debate, a partir de um diálogo teórico interdisciplinar, a respeito do lugar da área de Ciências Humanas na atual reforma do ensino médio. Procura-se defender a compreensão de que esta área do conhecimento construiu um potencial pedagógico capaz de contribuir na formação de sujeitos na contemporaneidade, constituindo um lugar de poder no processo de escolarização. E que mudanças no texto da LDB ancoradas em uma lógica empresarial-neoliberal de educação abrem as possibilidades de subalternização deste lugar.
A reforma do ensino médio: Regressão de direitos sociais
Authors: Moura Dante Henrique , Lima Filho Domingos Leite
Published: August 2017

No artigo, analisamos as relações entre o ensino médio e a educação profissional técnica de nível médio (EPTNM) face à reforma tratada na Lei 13.415/2017. Concluímos que a Lei integra uma racionalidade voltada a reconfigurar o Estado brasileiro em direção a uma nova fase de regressão social. Sobre a EPTNM, concluímos que a reforma sinaliza para o fortalecimento da dualidade educacional e de uma orientação mercadológica; precarização da docência
A reforma do ensino médio: Suprime direitos, privatiza a educação e terceiriza os/as trabalhadores/as escolares
Authors: CNTE CNTE
Published: August 2017

A Medida Provisória n. 746, enviada pelo Executivo Federal ao Congresso em 22 de setembro de 2016, foi aprovada na forma da Lei n. 13.415, sancionada em 16 de fevereiro de 2017. A proposta possui vício de origem, de forma e de conteúdo, por não se pautar no debate democrático e nas reivindicações sociais, e não atende aos requisitos de relevância e urgência requeridos pelo art. 62 da Constituição, razão pela qual a CNTE ingressou com ação direta de inconstitucionalidade (ADI) contra a MP, posteriormente convertida em Lei Federal, sendo que se mantém válida e pendente de julgamento.

Authors: Saluja Gurucharan , Postolache Mihai
Published: August 2017

In this paper, we establish strong and ?-convergence theorems of modified
three-step iterations for total asymptotically nonexpansive mapping which is
wider than the class asymptotically nonexpansive mappings in the framework of
CAT(0) spaces. Our results extend and generalize the corresponding results of
Chang et al. [Demiclosed principle and ?-convergence theorems for total
asymptotically nonexpansive mappings in CAT(0) spaces, Appl. Math. Comput.
219(5) (2012) 2611-2617], Nanjaras and Panyanak [Demiclosed principle for

Complete convergence and complete moment convergence for extended negatively dependent random variables
Authors: Shen Aiting , Zhang Yu. , Wang Wenjuan
Published: August 2017

In this paper, we provide some probability and moment inequalities
(especially the Marcinkiewicz-Zygmund type inequality) for extended
negatively dependent (END, in short) random variables. By using the
Marcinkiewicz-Zygmund type inequality and the truncation method, we
investigate the complete convergence for sums and weighted sums of arrays of
rowwise END random variables. In addition, the complete moment convergence
for END random variables is obtained. Our results generalize and improve the
corresponding ones of Wang et al. [18] and Baek and Park [2].

OBJECTIVE

To determine whether the effects of intensive (<120 mmHg) compared with standard (<140 mmHg) systolic blood pressure (SBP) treatment are different among those with prediabetes versus those with fasting normoglycemia at baseline in the Systolic Blood Pressure Intervention Trial (SPRINT).

RESEARCH DESIGN AND METHODS

This was a post hoc analysis of SPRINT. SPRINT participants were categorized by prediabetes status, defined as baseline fasting serum glucose ≥100 mg/dL versus those with normoglycemia (fasting serum glucose <100 mg/dL). The primary outcome was a composite of myocardial infarction, acute coronary syndrome not resulting in myocardial infarction, stroke, acute decompensated heart failure, or death from cardiovascular causes. Cox regression was used to calculate hazard ratios for study outcomes with intensive compared with standard SBP treatment among those with prediabetes and normoglycemia.

RESULTS

Among 9,361 participants randomized (age 67.9 ± 9.4 years; 35.5% female), 3,898 and 5,425 had baseline prediabetes and normoglycemia, respectively. After a median follow-up of 3.26 years, the hazard ratio for the primary outcome was 0.69 (95% CI 0.53, 0.89) and 0.83 (95% CI 0.66, 1.03) among those with prediabetes and normoglycemia, respectively (P value for interaction 0.30). For all-cause mortality, the hazard ratio with intensive SBP treatment was 0.77 (95% CI 0.55, 1.06) for prediabetes and 0.71 (95% CI 0.54, 0.94) for normoglycemia (P value for interaction 0.74). Effects of intensive versus standard SBP treatment on prespecified renal outcomes and serious adverse events were similar for prediabetes and normoglycemia (all interaction P > 0.05).

CONCLUSIONS

In SPRINT, the beneficial effects of intensive SBP treatment were similar among those with prediabetes and fasting normoglycemia.
