Authors: Singh Anurag , Srivastava Neha , Tiwari Anshul , Srivastava Prachi
Published: July 2024

Background

Retinoblastoma is an aggressive cancer whose majority of patients are infants and children below the age of five. Approximately 80% of the total patients of retinoblastoma reside in low-to-middle-income countries like India. Lack of public and medical awareness and the absence of significant and regular clinical trials to test and authenticate new potential treatments impede the process of treating retinoblastoma. Attempts have been made to establish an effective way to diagnose retinoblastoma early so that it can be controlled in time, but so far, no significant success has been documented on that front. Moreover, recent strategies include computational and informatics solutions to identify potential targets at a genetic level to alter the expression of defective proteins in human subjects.

Aim

The main aim of the current study is to unravel the potential targets of Retinoblastoma, an aggressive pediatric cancer, utilizing an in silico network biology approach.

Methods

In the present study, we have utilized the gene network analysis approach to identify hub genes that affect the expression in the human system. We developed the Protein – Protein Interaction network utilizing 158 genes extracted from the NCBI OMIM database and identified 15 key genes, which were then subjected to metascape analysis to identify pathways and processes that affect and prioritize genes based on their significance scores. We were able to identify the following target genes: RBBP4, TFDP1, and RBBP7.

Result

RBBP4, TFDP1, and RBBP7 were identified as the most novel target genes against retinoblastoma after gene network and enrichment analysis.

Conclusion

Our in-silico network analysis unveiled the intricate mechanisms behind the progression of retinoblastoma by dissecting 158 associated genes in humans. Thus, this work not only illuminates the underlying dynamics of the disease but also offers a promising avenue for intervention.
Formulation and Evaluation of Niosomal Loaded Transdermal Patches for the Treatment of Osteoarthritis
Authors: Kajal  , Sharma Dev Raj , Pandit Vinay , Ashawat Mahendra
Published: July 2024

Introduction:

Osteoarthritis (OA) is a degenerative joint disease resulting from the breakdown of joint cartilage and underlying bone. The most common symptoms of osteoarthritis are joint pain and stiffness. The major hurdle in its treatment is that the oral administration of NSAIDs (Lornoxicam) causes side effects like GI side effects, cardiovascular problems, liver is-sues, or renal problems. Thus, there is a need to develop a Transdermal drug delivery system for the transport of drugs, which reduces side effects and has several benefits over oral delivery, and a Novel drug delivery system to enhance the permeation of drugs and give relief from symptoms of OA.

Objectives:

This work deals with the formulation and evaluation of niosomal-loaded Transdermal
Patches for the treatment of Osteoarthritis.

Method:

The Niosomes were prepared using the thin film hydration method, and Niosomal-loaded Transdermal patches were prepared using the Solvent Casting method. The preliminary evaluation and characterization studies were conducted to find the optimized formulation. The in-vitro release and ex-vivo permeation studies were investigated. Stability studies were also assessed.

Result:

The prepared Niosomes suspension (F2) was found to have particle size 320.2 nm, Zeta potential 23.9 mV, and Drug entrapment 79 ± 0.32%. The in-vitro drug release studies of opti-mized formulation show 96.44 ± 0.34 % drug release for 24 hours. Then, the optimized Niosome formulation (F2) was loaded into the transdermal patches. The in-vitro permeation studies of Nio-somal-loaded transdermal patch F1 (NLXTP) were performed, which showed a higher permeabil-ity than plain drug-loaded transdermal patch. F1 (NLXTP) followed Zero order release kinetic model, which shows a non-fickian controlled release diffusion mechanism. The ex-vivo drug re-lease studies of optimized formulation F1 (NLXTP) show 2.79 ± 0.76 (μg/ml) drug permeated for 8 hours with a flux value of 0.35 ± 0.55, and the percentage of drug retention was found to be 5.67%. The stability studies showed that patches were stable over 90 days in different atmospher-ic conditions.

Conclusion:

The Lornoxicam-loaded Niosomal transdermal patch was found to be a promising nano-drug-delivery alternative that showed better entrapment and release with a permeation pro-file for the daily management of osteoarthritis.

Published: July 2024

Introduction:

Soil bacteria that synthesize varying metallic NPs are underreported, even
though there is a promising mechanism in the bio-reduction of gold salts and the synthesis of gold
nanoparticles by different bacterial species.

Objective:

This study aimed to explore the ancillary potential of some soil microbes obtained from
a metal fabricating workshop for gold nanoparticles (AuNPs) synthesis.

Methods:

To evaluate the usefulness of these soil microbes, 1 mM chloroauric acid (HAuCl4.4H2O)
was bio-reduced using the wet biomass of these bacterial cells and characterized with UV-Vis spectrophotometer,
Fourier Transform Infra-red (FTIR), Scanning Electron Microscope (SEM), Energy
Dispersive X-ray (EDX), and X-ray Diffractometer (XRD).

Results:

Findings from this study showed that the studied bacterial isolates synthesized AuNPs with
absorbance peaks within the range of 500 and 600 nm. The FTIR analysis showed the involvement
of O-H, N-H, and C=O stretch of alcohol, amine, and amide groups, respectively. The SEM images
analyzed with Image J reported a mean area size between 17-184 nm. The EDX showed Klebsiella
africana (C11), and Bacillus subtilis (A12) had the lowest (7.32%) and highest (51.26%) weight
percentages of AuNPs, respectively.

Conclusion:

Gold nanoparticles have been found most appropriate for several novel applications,
and this work has provided further understanding of the capacity of naturally occurring bacteria to
be non-selective in the bio-reduction of gold salts, hence expanding their potential uses.

Published: July 2024

The study aimed to evaluate the potential of boiler ash from palm oil mills to improve the quality of acid mine drainage (AMD). The experiment was conducted using boiler ash with five doses of 0, 3, 6, 9, 12, and 15 mg. Quicklime was used as a comparison material with doses of 0, 0.02, 0.03, 0.05, 0.1, and 0.3 mg. Boiler ash and quicklime were added to each 500 mL AMD. The parameters of the AMD quality measured were pH, dissolved iron (Fe) and manganese (Mn), and the precipitates of Fe and Mn. The results showed that the addition of boiler ash and quicklime into AMD increased the pH and decreased the concentration of dissolved Fe and Mn and increased the precipitate of Fe and Mn. The pH value of AMD increased with increasing doses of boiler ash and quicklime. An increase in the pH value was followed by a decrease in the dissolved Fe and Mn and anincrease in the Fe and Mn precipitate. The highest pH values, Fe and Mn precipitates, and the lowest dissolved Fe and Mn were obtained by the treatment of 15 mg/L boiler ash and 0.3 mg/L quicklime. The boiler ash showed promising potential as an alternative neutralizing reagent to improve AMD even though the amount of boiler ash needed to repair AMD was more than quicklime.

Published: July 2024

A simple and sensitive indirect spectrophotometric method is developed for the assay of Adrenaline, Dopamine hydrochloride, and Methyldopa in their pure and pharmaceutical preparations. The method is based on the principle of oxidation of the above drugs with a known amount of the oxidizing agent, N-bromosuccinimide (NBS), in hydrochloric acid. The unreacted oxidant bleaches Ponceau 4R dye, then the absorbance of the remaining dye (ΔA) is measured at 507 nm. The method obeyed Beer’s law within the concentration range of 3.5-10, 4-15, and 5-20 μg/mL, with molar absorptivity values of 8.01×104, 5.32×104, and 4.93×104 L. mol-1cm-1 for Adrenaline, Dopamine hydrochloride and Methyldopa, respectively. The recovery ranged between 99.15 to 100.61%, and the relative standard deviation (RSD) was less than 1.42 % for all drug compounds. The method was applied successfully to pharmaceutical preparations for the studied medicinal compounds from different origins, as its results were in good agreement with the original content of the drugs in their pharmaceutical formulations and with the standard addition procedure, which proved that there was no interference by the excipients.

Authors: Miftachurrochmah Anis , Fibrianto Kiki , Bekti Sunarharum Wenny
Published: July 2024

Bekasam is a fish that is spontaneously fermented by adding salt and a source of carbohydrates (such as cooked white rice). This traditional food is often found in several regions of Indonesia, especially in South Sumatra, South Kalimantan, and North Sulawesi. Bekasam is traditionally produced to preserve fish during the harvest season. This review aims to present information on the historical background of bekasam, its manufacturing process, chemical characteristics, the types of microflora that exist within it, and the potential utilization of bekasam as a source of umami in dishes. The methodology for this study included a combination of literature review, observational interviews with traditional bekasam producers, experimental bekasam processing, and thorough documentation. A total of 60 articles were collected and chosen based on appropriate criteria. The results of the review article offer several explanations, based on historical aspects bekasam is an adaptation of Chinese cuisine introduced by traders who visited Sriwijaya. In the South Sumatra region, especially among the Ogan and Komering tribes, clay jars left by the Chinese are used to store bekasam in the kitchen. The Komering tribe refers to the fermentation of bekasam as sam-sam. Various microbes are found in bekasam, with the main constituent being Lactobacillus spp., and a significant presence of Lactobacillus plantarum. During fermentation, the proteins in the raw materials of bekasam are degraded into simple compounds, mainly amino acids. Glutamate and aspartate had the highest values in the total composition of the other amino acids. These two amino acids contribute to the umami taste of food products. After exceeding the threshold for glutamate and aspartate, bekasam has the potential to contribute to the umami taste. Due to its umami potential, bekasam has been developed into various cuisines, including fried bekasam, sautéed bekasam, and chili sauce.

Application of two-lever baglog pressing machine technology to improve the production of oyster mushroom cultivation
Authors: Damayanti Retno
Published: July 2024

The baglog pressing process in the Ngadi Oyster Mushroom Cultivation Community Group in Gunungronggo Village is still done manually, by compressing the media in a plastic bag with a bottle or plastic pipe several times until it is solid. This work requires quite a lot of labor and a long time. The level of success of this process really depends onthe skills and accuracy of the workers. The results of compacting the media in this way are sometimes unsatisfactory, because there are still air spaces in the media, so oyster mushrooms cannot grow. Problems that can be identified in SMEs are the division of labor duties for the printing and steaming processes, as well as the lack of experienced workers who can compact baglog properly. So it is necessary to apply a two-lever baglog pressing machine which aims to increase production capacity. The results of the activity show an increase in baglog production capacity, from 60 baglog/day with 2 workers to 300 baglog/day with a baglog press machine, with a printing process time of 5 hours/day. Production increased 500% compared to before using the tool. This capacity meets the needs for the steaming process, where the steamer capacity owned by SMEs is 215 baglogs/process/day

Authors: Ditya Hafiz Rosyidi  , Mohammad Sulton  , Puput Risdanareni
Published: July 2024

Rendahnya konsumsi fly ash di Indonesia perlu diatasi untuk menghindari penimbunan material ini. Penggunaan bahan ini sebagai bahan baku untuk memproduksi agregat ringan menjadi salah satu solusi alternatif untuk meningkatkan konsumsi fly ash, karena agregat ini memiliki porsi yang cukup tinggi dalam campuran beton. Namun, karena agregat ringan memiliki porositas yang tinggi, maka daya tahan agregat ringan terutama dalam hal penyerapan air di lingkungan yang agresif perlu diteliti. Oleh karena itu, penelitian ini bertujuan untuk mengetahui durabilitas beton yang mengandung fly ash-based lightweight aggregate (FA LWA) di lingkungan garam. Lingkungan garam ditirukan dengan larutan natrium klorida dan natrium sulfat. Pada produksi beton, aggregat kasar disubsitusi dengan FA dan EC LWA dengan kadar penggantian 50 dan 100%. Selanjutnya sifat fisik, mekanik dan durabilitas beton dinilai dengan melakukan uji berat jenis, kuat tekan dan kecepatan kapiler di lingkungan garam. Hasil penelitian menunjukkan bahwa berat jenis berbanding terbalik dengan persentase kandungan LWA yang digunakan. Selain itu, dari hasil uji serapan air kapiler beton menunjukkan bahwa beton yang mengandung FA LWA memperoleh nilai serapan yang lebih tinggi dibandingkan dengan beton kontrol. Berdasarkan hasil uji serapan air kapiler dengan menggunakan larutan yang berbeda, menunjukkan bahwa beton FA LWA lebih tahan dalam lingkungan basa atau mengandung larutan garam (NaCl). Hasil penelitian ini berkontribusi memberi terobosan baru bahwa konsumsi fly ash dapat ditingkatkan dengan mentransformasi fly ash menjadi aggregate ringan buatan yang memiliki ketahanan tinggi di lingkungan air laut.

Proporsi sepeda motor terhadap arus lalu lintas total keseluruhan simpang 0.815. Penelitian ini bertujuan untuk mengetahui nilai derajat kejenuhan yang menggambarkan kinerja dari simpang yang diteliti. Analisis arus lalu lintas puncak simpang, kapasitas simpang, dan nilai derajat kejenuhan mengacu pada Pedoman Kapasitas Jalan Indonesia 2014. Sekalipun pada perbatasan kota, perilaku lalu lintas yang melalui simpang ini masih memperlihatkan karakteristik lalu lintas perkotaan, yaitu pola arus lalu lintas berulang periodik mingguan. Sehingga survei lalu lintas dilaksanakan pada Senin, Rabu mewakili populasi hari kerja normal: Senin sampai Kamis dan survei Sabtu mewakili hari-hari akhir pekan. Arus lalu lintas yang masuk ke lokasi simpang dari tiga lengan divideokan dengan kamera. Tiap lengan disorot dengan satu kamera. Data lalu lintas dari tiap lengan per arah pergerakan per jenis kendaraan dicacah dari rekaman video. Hasil pengolahan data dianalisis dan diperoleh arus lalu lintas puncak sore hari yang diwakili lalu lintas hari kerja. Derajat kejenuhan (Dj) = 0.64. Arus lalu lintas belum jenuh. Kesemrawutan berasal dari sepeda motor yang mendominasi arus lalu lintas dengan proporsi 0.815 dan pelanggaran contra flow. Tindakan untuk menurunkan kesemrawutan, yaitu menambah rambu larangan contra flow pada Jalan Andi Tonro. Pemasangan kamera CCTV yang menyorot pada keempat-empat lengan. Disertai dengan penerapan Electronic Traffic Law Enforcement pada Kabupaten Gowa sehingga pengendara sepeda motor akan terpaksa disiplin.

The known variants of volumetric hydraulic drives of lifting and technological mechanisms are considered and analyzed. The areas of application of pumping and accumulator hydraulic drives, with various types of regulation, and options for their implementation as drives of a cargo winch of a bridge crane are considered. It is shown that the operation of the volumetric hydraulic drives of the cargo winch, along with volumetric and throttle control, can be performed by a relay method. It is noted that the cyclical operation of lifting mechanisms during lifting and lowering of cargo allows for mechanical and hydraulic energy recovery within the working cycle, which is a promising way to significantly increase the efficiency of their work. The analysis of the existing designs of hydraulic drives of technological machines, allowing to recover the potential energy of working bodies with cargo, is carried out. It is proposed as an alternative to the known hydraulic drives of the cargo winch of the bridge crane, a hydraulic drive with relay control. The efficiency of such a drive is shown, according to the indicators of the nominal pressure utilization coefficient and the energy intensity of the working fluid, in the case of the implementation of mechanical and hydraulic energy recovery in the working cycle in it. The mechanical and hydraulic circuits of such a drive are examined. An algorithm of mathematical model of its operation with consideration of different phases of cargo movement is proposed and its investigation is carried out. The possibility of fulfilling the safety conditions of operation of a hydraulic drive with relay control, in terms of ensuring the requirements for the uniformity of cargo movement, is analyzed.

Published: July 2024

Objective: This study aimed to determine the prevalence rate and assess knowledge and attitudes among secondary students in Sulaimani city.
Methods: A cross-sectional study was conducted among school students, from eight randomly selected secondary schools in Sulaimani city, Iraq. 1200 students participated in this study during six months from October 2022 to April 2023. The respondents were explained about each section of the questionnaire form. It describes behaviors, knowledge, beliefs, opinions, and other variables related to tobacco use.  
Results: The prevalence rate of current tobacco use (all types) is 21.8%, from this rate; 13.2% were cigarette smoking, 11.9% waterpipe, 24.7% used electronic smoke such as vape and pods and 50.2% of students used all types of tobacco product. The prevalence rates of tobacco use in males (31.3%) and females (12.1%). The rates were higher among students whose mother and father, schoolmates, relatives, and friends were smokers than those whose parents, schoolmates, relatives, and friends were non-smokers. A higher rate of smokers have not thought about the harmful of other people’s cigarettes on them, 16.7%, 25%, 9.9%, and 4.8% of smokers have not thought definitely, probably not, probably yes, and definitely yes. Regarding the attitude of the smokers, it showed statistically that there were significant associations for example only 6.6% of smokers were with the banning of smoking in public places while 21.7% of them were with not banning smoking in public places. 
Conclusion: Despite the prevalence rate of smoking in Sulaimani City being relatively lower than in other cities in Iraq the rate is still high. The rate was higher in males than females. In addition, there were factors connected with smoking initiation which are parents, schoolmates, relatives, and friends smoking. A higher rate of smokers did not think about the harmful of other people’s cigarettes to them and a lower rate of smokers were with the banning smoking in public places.

Authors: Jali Ibtisam
Published: July 2024

Objective: This work aimed to assess the serum level of cystatin C in systemic lupus erythematosus (SLE) patients and to determine the relation to disease characteristics and damage.
 
Methods: The study included 33 SLE patients presenting to the Internal Medicine and Rheumatology Department and Outpatient clinic, King Abdulaziz University, Saudi Arabia. The medical history, clinical examination, laboratory investigations and medications received by the patients were recorded. The systemic lupus international collaborating clinics damage index (SLICC-DI) was assessed. Serum cystatin C was measured using the immune-nephelometric method.
 
Results: The mean age of the patients was 35.3±10.7 years; 28 females and 5 males (F:M  5.6:1), disease duration 5.5±3.1 years and their age at onset was 27.9±10.6 years. Serum cystatin C level was significantly higher in patients with lupus nephritis (LN) (2.47±1.57 mg/L vs v mg/L, p=0.003) and diabetes (4.92±0.05 mg/L vs 1.93±1.34 mg/L; p<0.0001) and was lower in those with thyroid dysfunction (1.41±0.75 mg/L vs 2.3±1.59 mg/L, p=0.047). There was a significant correlation between the serum cystatin C level with proteinuria (r=0.57, p=0.011) and with the SLICC-DI (r=0.42,p=0.016). Serum cystatin C could discriminate patients with LN at cut-off value of 0.904 mg/L with area under the curve of 0.765, sensitivity 87% and specificity 50%; p=0.017.
 
Conclusion: The remarkable association between cystatin C and LN is confirmed and an emerging role is noted in reflecting the extent of disease damage. The likely association with diabetes and thyroid dysfunction should also be taken into consideration when deciding treatment regimens for LN patients.
