This research was carried out from December to May 2018, at Greenhouse of Supervision and Certification of Food Crops and Horticulture Banjarbaru. The objective of the study was to examine the effect of organic fertilizer type and dosage and to know the best dosage of each type of organic fertilizer on the physiological characteristics of shallots on ultisol soil. The experimental method is designed based on a two-factor nested design with Completely Randomized Compact Design (RAL) design. The first factor is the type of organic fertilizer (J) consisting of two levels namely cow dung (j1) and chicken manure (j2), the second factor is the organic fertilizer dosage nested in the organic fertilizer consisting of four levels of 10 t ha-1 (d1); 20 t ha-1 (d2); 30 t ha-1 (d3) and 40 t ha-1 (d4). Treatment was repeated 4 times, each experimental unit consisting of 3 polybags. Observation variables were leaf N content, leaf chlorophyll content, the water content of bulbs and volatile oil content on bulbs. The results showed that the type and quantity of organic manure of cow dung and chicken manure had no significant effect on all observed variables. Limiting factors such as low light intensity are suspected to cause the type treatment and organic fertilizer dosage does not affect all observed variables. Light intensity and humidity during cultivation are incompatible with the requirements of shallots grow is also seen in the long period of vegetative shallots plant which is a manifestation of the plant's response to environmental conditions.

One of the impacts of reclamation of swamps is poison substances in the water channels, which can cause to pyrite oxidation, sedimentation and accumulation of toxic substances in secondary channels. The reclamation channel unit in Semangat Karya Village has a water pH of ± 3 and has the iron level of 4.95 mg / l. Based on South Kalimantan Provincial Governor Regulation Year 2007, pH grade and iron concentration are over the quality standard, while the water is consumed by the residents for everyday intentions. One of the technologies that are applied to increase the pH and to minimize the concentration of iron (Fe) is constructed wetland with the horizontal sub-surface flow (CW-HSSF). The objectives of this research were to study the dynamics of pH and Fe in the media acid sulfate soils mixed with organic fertilizer (bokashi) 10% at CW-HSSF system using Purun Tikus (Eleocharis dulcis) and Kalakai (Stenochlaena palustris). The conclusion of this research indicated that pH value and absorption of Fe in CW-HSSF using Purun Tikus (Eleocharis dulcis) was better than Kalakai (Stenochlaena palustris).

Study of sulfate-reducing ammonium oxidation process and its microbial community composition
Authors: Zhang Dandan , Cui Li , Wang Hui , Liang Jiyan 
Published: January 2019

Abstract
In this study, the simultaneous removal of ammonium and sulfate was detected in a self-designed circulating flow reactor, in which ammonium oxidization was combined with sulfate reduction. The highest removal efficiencies of NH4+-N and SO42–S were 92% and 59.2%. NO2− and NO3− appeared in the effluent, and experimental studies showed that increasing the proportion of N/S in the influent would increase the NO2− concentration in the effluent. However, N/S [n(NH4+-N)/n(SO42–S)] conversion rates during the experiment were between 2.1 and 12.9, which may have been caused by the experiment's complex process. The microbial community in the sludge reactor included Proteobacteria, Chloroflexi, Bacteroidetes, Chlorobi, Acidobacteria and Planctomycetes after 187 days of operation. Proteobacteria bacteria had a more versatile metabolism. The sulfate-reducing ammonium oxidation (SRAO) was mainly due to the high performance of Proteobacteria. Nitrospirae has been identified as the dominant functional bacteria in several anammox reactors used for nitrogen removal. Approximately 12.4% of denitrifying bacteria were found in the sludge. These results show that a portion of the nitrogen was converted by nitrification-denitrification, and that traditional anammox proceeds simultaneously with SRAO.

Published: January 2019

Background:In Algeria, important quantities of secondary date variety (Phoenix dactylifera L.) are generated in each campaign; their chemical composition is similar to that of commercial dates. The present work aims to valorize this common date variety (Degla-beida) which is often poorly exploited.Methods:In this context, we tried to prepare syrup from the secondary date variety and evaluate the effect of conventional extraction (CE) or water bath extraction (WBE) and alternative extraction (microwaves assisted extraction (MAE) and ultrasound-assisted extraction (UAE)) on its total sugar content (TSC), using response surface methodology (RSM). Then, the analysis of individual sugars was performed by high performance liquid chromatography (HPLC).Results:Maximum predicted TSC recoveries under the optimized conditions for MAE, UAE and CE were 233.248 ± 3.594 g/l, 202.889 ± 5.797 g/l and 233.535 ± 5.412 g/l, respectively, which were close to the experimental values: 233.796 ± 1.898 g/l; 202.037 ± 3.401 g/l and 234.380 ± 2.425 g/l. HPLC analysis revealed high similarity in the sugar composition of date juices obtained by MAE (60.11% sucrose, 16.64% glucose and 23.25% fructose) and CE (50.78% sucrose, 20.67% glucose and 28.55% fructose), although a large difference was detected for that obtained by UAE (0.00% sucrose, 46.94% glucose and 53.06% fructose).Conclusion:Microwave-assisted extraction was the best method for the preparation of date syrup with an optimal recovery of total sugar content. However, ultrasound-assisted extraction was the best one for the preparation of date syrup with high content of reducing sugars.

Published: January 2019

Background:
Extending the shelf-life of food products is very important for food producers,
and one of its most significant methods is gamma irradiation.

Objective:
The aim of this study is to evaluate extending the shelf-life of whole-wheat flour using
gamma irradiation and to study the organoleptic and physical characteristics of the cakes made with
irradiated flour.

Methods:
900 g packed flour samples were irradiated with different doses of 0.2, 0.5, 2 and 5 kGy of
gamma irradiation using Caesium-137 source.

Results:
Based on the results, insect growth was not observed in any of the irradiated flour samples
up to 180 days after production. The total number of bacteria and the number of mold and yeast significantly
reduced during 180 days of storage. With increasing the irradiation dose, the height of the
baked cakes was significantly reduced, the size of the air bubbles inside the cake decreased, and the
color of the cakes became darker so that a dark and different color was observed at a dose of 5 kGy.

Conclusion:
By applying a dose of 5 kGy irradiation, the shelf-life of flour can be longer, with
inconsiderable organoleptic changes of baked cakes.

Authors: Oori Mehdi Jafari , Mohammadi Farahnaz , Norozi Kian , Fallahi-Khoshknab Masoud , Ebadi Abbas , Gheshlagh Reza Ghanei 
Published: January 2019

Introduction:
Prevalence of hypertension (HTN) is increasing in the developing countries
like Iran. Various studies have reported different rates of HTN in Iran. The purpose of this
study was to estimate an overall prevalence of HTN in Iran.

Methodology:
Using the English and Persian key derived from Mesh, the databases including
MagIran, Iran Medex, SID, Web of Sciences, PubMed, Science Direct and Google Scholar as a
searching engine were reviewed: from 2004 to 2018. The overall prevalence of MA was estimated
using Random effect model. The I2 test was used to assess the heterogeneity of the studies. Additionally,
the quality of studies was evaluated using a standard tool. Publication bias was conducted
with the Egger test. Meta-regression and analysis of subgroups were analyzed based on variables
such as age, marital status, region and tools. Data were analyzed using STATA 12 software.

Results:
Analysis of 58 primary articles with a sample size of 902580 showed that the prevalence of
HTN in Iran was 25% (with 95% CI of 22-28). The highest prevalence of HTN was related to elderly
(42%). The prevalence of HTN was 25% (95% CI: 19-31) in women and 24% (95% CI: 20-28)
in men with no significant difference (p = 0.758). The results also indicated that the prevalence of
HTN was not related to the year of studies (p = 0.708) or sample size (p = 769).

Conclusion:
Despite the advancements in science and technology, along with health and prevention
of diseases, the overall prevalence of HTN raised in Iran. Since HTN is a silent disease with significant
health consequences and economic burden, programs designed to better HTN control seem
vital to enhance community health.
Implantable Cardioverter-Defibrillators in Patients with ESRD: Complications, Management, and Literature Review
Authors: Mehdi Bayati , Kaveh Hosseini , Ali Vasheghani-Farahani 
Published: January 2019

Background:
Cardiovascular diseases are the leading cause of death among dialysis patients,
accounting for about 40% of all their mortalities. Sudden cardiac death (SCD) is culpable for
37.5% of all deaths among patients with end-stage renal disease (ESRD). Implantable cardioverterdefibrillators
(ICDs) should be considered in dialysis patients for the primary or secondary prevention
of SCD. Recent studies on the implementation of ICD/cardiac resynchronization therapy do
not exclude patients with ESRD; however, individualized decisions should be made in this group of
patients. A thorough evaluation of the benefits of ICD implementation in patients with ESRD requires
several large-scale mortality studies to compare and follow up patients with ESRD with and
without ICDs. In the present study, we sought to determine and clarify the complications associated
with ICD implementation and management thereof in patients suffering from ESRD.

Methods:
To assess the complications allied to the implementation of ICDs and their management
in patients with ESRD, we reviewed available related articles in the literature.

Results and Conclusions:
ICD implementation in dialysis patients has several complications,
which has limited its usage. Based on our literature review, the complications of ICD implementation
can be categorized as follows: (1) Related to implantation procedures, hematoma, and pneumothorax;
(2) Related to the device/lead such as lead fracture and lead dislodgment; (3) Infection;
and (4) Central vein thrombosis. Hence, the management of the complications of ICDs in this specific
group of patients is of vital importance.

Authors: Fartas Fuzi M. , Abdullah Jaafar , Yusof Nor A. , Sulaiman Yusran , Saiman Mohd I. , Zaid Mohd H.M. 
Published: January 2019

Background:Bisphenol A (BPA) is considered one of the most common chemicals that could cause environmental endocrine disrupting. Therefore, there is an increasing demand for simple, rapid and sensitive methods for BPA detection that result from BPA leaching into foods and beverages from storage containers. Herein, a simple laccase electrochemical biosensor was developed for the determination of BPA based on Screen-Printed Carbon Electrode (SPCE) modified graphenegold/ chitosan. The synergic effect of graphene-gold/chitosan nanocomposite as electrode modifier greatly facilitates electron-transfer processes between the electrolyte and laccase enzyme, thus leads to a remarkably improved sensitivity for bisphenol A detection.Methods:In this study, laccase enzyme is immobilized onto the Screen-Printed Carbon Electrode (SPCE) modified Graphene-Decorated Gold Nanoparticles (Gr-AuNPs) with Chitosan (Chit). The surface structure of nanocomposite was studied using different techniques including Field Emission Scanning Microscopy (FESEM), TRANSMISSION Electron Microscopy (TEM), Raman spectroscopy and Energy Dispersive X-ray (EDX). Meanwhile, the electrochemical performances of the modified electrodes were studied using Cyclic Voltammetry (CV) and Differential Pulse Voltammetry (DPV).Results:The developed laccase biosensor offered excellent analytical performance for the detection of BPA with a sensitivity of 0.271 μA/μM and Limit of Detection (LOD) of 0.023 μM, respectively. Moreover, the constructed biosensor showed good reproducibility, selectivity and stability towards BPA. The sensor has been used to detect BPA in a different type of commercial plastic products as a real sample and satisfactory result was obtained when compared with the HPLC method.Conclusion:The proposed electrochemical laccase biosensor exhibits good result which is considered as a promising candidate for a simple, rapid and sensitive method especially in the resource- limited condition.

Authors: Tara Nusrat , Siddiqui Sharf Ilahi , Rathi Geetanjali , Chaudhry Saif Ali , Inamuddin  , Asiri Abdullah M. 
Published: January 2019

Background:
The huge quantity of wastewater, containing poisonous and hazardous dyes,
is released by various industries which pollute water in direct and indirect ways. Most of the dyes are
a dangerous class of water contaminants which have affected the environment drastically. Some dyes
such as congo red, rhodamine B, methylene blue, methyl violet, and crystal violet are a serious threat
to human beings.

Remediation Method:
Numerous methods are available for the removal of dyes from water.
Adsorption, being a superior and eco-friendly technique, has advantage of eliminating organic dyes
because of the availability of materials as adsorbents. The inexpensive nanomaterials are a more attractive
choice for remediation of various dyes due to their unique properties and offer an adequate
pathway to adsorb any organic dye from water to overcome its hazardous effects on human health.

Results:
In this review, we have discussed the latest literature related to various types of synthesis,
characterization and uses as adsorbent for highly adsorptive removal capacity of nanoparticles for organic
dyes.

Conclusion:
Adsorption technology provides an attractive pathway for further research and improvement
in more efficient nanoparticles, with higher adsorption capacity, for numerous dyes to
eliminate the dyes discharged from various industries and thus reduce the contamination of water.
Therefore, nanocomposites may contribute to future prospective water treatment process.
Cutaneous Adverse Events of Immune Checkpoint Inhibitors: A Summarized Overview
Authors: Plachouri Kerasia-Maria , Vryzaki Eleftheria , Georgiou Sophia 
Published: January 2019

Background:The introduction of Immune Checkpoint Inhibitors in the recent years has resulted in high response rates and extended survival in patients with metastatic/advanced malignancies. Their mechanism of action is the indirect activation of cytotoxic T-cells through the blockade of inhibitory receptors of immunomodulatory pathways, such as cytotoxic T-lymphocyte-associated antigen-4 (CTLA-4), programmed cell death protein-1 (PD-1) and its ligand (PD-L1). Despite their impressive therapeutic results, they can also induce immune-related toxicity, affecting various organs, including the skin.Objective:To provide an updated summarized overview of the most common immune-mediated cutaneous side effects and their management.Method:English articles derived from the databases PubMed and SCOPUS and published between 2009 and 2018, were analyzed for this narrative review.Results:The most common adverse cutaneous reactions include maculopapular rash, lichenoid reactions, vitiligo and pruritus, with severity Grade 1 or 2. Less frequent but eventually life-threatening skin side effects, including Stevens-Johnson syndrome, Drug Reaction with Eosinophilia and Systemic Symptoms and Toxic Epidermal necrolysis, have also been reported.Conclusion:Basic knowledge of the Immune-Checkpoint-Inhibitors-induced skin toxicity is necessary in order to recognize these treatment-related complications. The most frequent skin side effects, such as maculopapular rash, vitiligo and pruritus, tend to subside under symptomatic treatment so that permanent discontinuation of therapy is not commonly necessary. In the case of life-threatening side effects, apart from the necessary symptomatic treatment, the immunotherapy should be permanently stopped. Information concerning the management of ICIs-mediated skin toxicity can be obtained from the literature as well as from the Summary of Product Characteristics of each agent.
