Produksi Polyhydroxybutyrate Menggunakan Mikroba yang Dimodifikasi Secara Genetik: Tinjauan Terhadap Keamanan dan Keberlanjutan
Authors: Susanto Feri 
Published: October 2023

Polyhydroxybutyrate (PHB) is a biocompatible and biodegradable polymer that has the potential to replace fossil-derived polymers. The enzymes involved in PHB biosynthesis are β-ketothiolase (PhaA), acetoacetyl-CoA reductase (PhaB), and PHA synthase (PhaC). PHB has properties similar to conventional plastics but can be decomposed naturally by microorganisms in a suitable environment. The production of PHB using genetically modified microbes has become the focus of research in an effort to produce PHB efficiently and sustainably. Production sustainability refers to the ability of an industry to maintain sustainable production without destroying the environment and limited natural resources. By using genetically modified microbes, PHB production can be significantly increased, making it a more sustainable and environmentally friendly alternative to conventional plastics. Non-biodegradable conventional plastics cause serious environmental problems. Therefore, the production of PHB using genetically modified microbes is becoming a relevant topic in the industry today.

Published: October 2023

Muara Kali Ijo is the place where rivers flow in Kebumen Regency, which carry a lot of domestic wastes resulting from sanitation activities, namely detergent. The study aims to determine the quality of Muara Kali Ijo Waters based on MBAS concentration (Methylen Blue Active Substances). MBAS is a standard method for determining the concentration of anionic surfactants in detergents. This study uses descriptive methods with purposive random sampling techniques. Sampling was carried out on March 11, 2023 with a total of five stations. The results of the analysis of the MBAS concentration in the BBSPJPPI laboratory ranged from 0.031 – 0.064 mg/L and the measurement of water quality parameters was still relatively good, below the quality standard threshold. PCA results show that there is a negative correlation between MBAS concentration and water quality parameters. Productive anthropogenic activities around the area have a potential to contribute detergent waste from washing activities and increase MBAS concentrations.

Published: October 2023

AbstractÂ Mahseer "dewa" (Tor soro), snakehead "gabus" (Channa striata), and bagrid catfish "baung" (Hemibagrus nemurus) are local specific fish species that are promising to be developed as freshwater aquaculture commodities in Indonesia. Disease cases/outbreaks in those fish farming have often been reported, however, there is not much information on the epizootiology and disease status of those fish species. The susceptibility of those fish to parasitic infection was evaluated by natural and artificial infection. Natural infection was conducted by randomly sampling 20 fish at 5-day intervals and lasting for 30 days. In artificial infection, 150 tested fish cohabited with 40 parasite-carrying fish that were known to be definitely infected by the parasite. The observation was carried out by sampling 20 fish at 5-day intervals and lasting for 30 days. The results showed that the three fish species were susceptible to infection with Trichodina spp, Epistylis spp, Tetrahymena spp, Ichtyophthirius multifiliis, Dactylogyrus spp, and Gyrodactylus spp, while the helminth parasite Pallisentis nagpurensis (Acanthocephala) was only identified in snakehead. A number of parasites such as I. multifiliis, Dactylogyrus spp., and Gyrodactylus spp. are likely to be potential obstacles in the cultivation of those fish species, especially in hatcheries and nurseries.Â Keywords: mahseer, snakehead, bagrid catfish, parasites

Authors: El Mobadder Marwan , Nammour Samir 
Published: October 2023

Dentinal Hypersensitivity (DH), a prevalent oral health issue affecting approximately one-third of adults. In this six-months retrospective study, a comparison was made to assess the effectiveness of two diode lasers with different wavelengths (980 nm and 1064 nm) in the treatment of tooth affected by DH. In total, 160 patients were divided into two treatment groups: one receiving treatment with a 980 nm diode laser (n=80) and the other with a 1064 nm diode laser (n=80). Pain was assessed using the Visual Analogue Scale (VAS) at baseline, immediately post-treatment, and at 3- and 6-months follow-up. Both groups followed the same treatment protocol, involving the application of a graphite paste to the exposed dentin before laser irradiation. Both lasers operated at an output power of 0.5 W in continuous and non-contact mode, with a 320 µm spot size. A significant reduction in mean VAS scores at all follow-up intervals compared to baseline was noted. 980 nm group had mean VAS scores of 7.9, 2.36, 2.31, and 2.38, while the 1064 nm group had scores of 8.01, 1.01, 1.16, and 1.13 at baseline, immediately post-treatment, and at 3 and 6 months, respectively. At all times of follow-up, the 1064 nm wavelengths showed a statistically significant reduction in mean values of VAS compared to the 980 nm. The findings may inform future research on optimizing laser-based treatments for DH.

Published: October 2023

Abstract
In the realm of fuel desulfurization, the application of nanocomposite catalysts has emerged as a promising solution to effectively eliminate sulfur compounds. This research endeavors to enhance the process of oxidative desulfurization of fuel through the development of a novel nanocomposite catalyst composed of iron-molybdenum oxide immobilized on a gamma alumina substrate. The objective is to investigate the catalytic performance of this material for efficient sulfur removal from fuel, thereby contributing to the optimization of fuel quality and reducing detrimental environmental impacts. XRD, FT-IR, SEM, and BET analyses identified the synthesized nanocomposite catalysts, which include iron-molybdenum oxide based on γ -alumina. The effect of different metal loading percentages on the base and variables affecting the process (temperature, reaction time, O/S molar ratio, and extraction solvents) have been investigated. Dimethylformamide solvent was identified as the best solvent for extracting the reaction products in this process. The best conditions obtained in this work (O/S = 6:1, 60℃, 90 min) and the synthesized catalyst with 5% by weight was identified as the most efficient catalyst, which removed 88% of sulfur compounds in the fuel.

Methods
This was a retrospective analysis of 92 patients with femoral neck fractures who were classified into high ambulatory status (HG) and low ambulatory status (LG) groups. Ambulatory status was assessed before surgery, one week after surgery, at discharge, and during the final follow-up. To evaluate sarcopenia, muscle mass and fatty degeneration of the gluteus medius, gluteus maximus, paraspinal, and psoas muscles were measured using preoperative CT.
Results
The mass of the gluteus medius and paraspinal muscles was significantly correlated with ambulatory status before the injury, at discharge, and during the final follow-up.
Conclusions
Measurement of the gluteus medius and paraspinal muscles has the potential to evaluate sarcopenia and predict ambulatory status after femoral neck fractures.

Abstract
Bone homeostasis is maintained by osteoclast-mediated bone resorption and osteoblast-mediated bone formation. A dramatic decrease in estrogen levels in postmenopausal women leads to osteoclast overactivation, impaired bone homeostasis, and subsequent bone loss. Changes in the gut microbiome affect bone mineral density. However, the role of the gut microbiome in estrogen deficiency-induced bone loss remains unknown. In this study, we found that the abundance of Clostridium sporogenes (C. spor.) and its derived metabolite, indole propionic acid (IPA), were decreased in ovariectomized (OVX) mice. In vitro assays suggested that IPA suppressed osteoclast differentiation and function. At the molecular level, IPA suppressed receptor activator of nuclear factor kappa-Β ligand-induced pregnane X receptor (PXR) ubiquitination, leading to the degradation of PXR and release of its binding p65. In vivodaily IPA administration or repeated C. spor. colonization protected against OVX-induced bone loss. To protect live bacteria from the harsh gastric environment and delay the emptying of orally administered C. spor. from the intestine, a C. spor.-encapsulated silk fibroin (SF) hydrogel system was developed, which achieved bone protection in OVX mice comparable to that achieved with repeated germ transplantation or daily IPA administration. Overall, we found that gut C. spor.-derived IPA was involved in estrogen deficiency-induced osteoclast overactivation by regulating the PXR/p65 complex. The C. spor.-encapsulated SF hydrogel system is a promising tool for combating postmenopausal osteoporosis without the disadvantages of repeated germ transplantation.

Abstract

The overall aim of this study was to "investigating the effectiveness of resilience-based training on increasing marital compatibility and quality of life and reducing marital dissatisfaction among couples seeking divorce". This study can be categorized as applied research. This research was a quasi experimental study with a pretest-posttest design with experimental and control groups. The statistical population studied consisted of all couples seeking divorce in Tehran who had been referred to family law offices and judicial complexes. Thirty people were selected by voluntary sampling and randomly assigned to experimental and control groups. Training on resilience took place weekly for 10 sessions, with each session lasting one hour, while control groups did not receive the Resilience Training Package (Krager, 2006) [1], while the control group received no intervention. The data collection tools were the Spanier Dyadic Adjustment Scale (DAS), World Health Organization Quality of Life Questionnaire (WHOQOL-BREF), and Couple Burnout Measure (CBM). To calculate the reliability of the questionnaire items, Cronbach's alpha was used to determine the reliability of individual components and all the questions of the Spanier's marital compatibility, quality of life, and marital dissatisfaction questionnaires. The reliability coefficient for the entire marital compatibility questionnaire was 91%, quality of life was 89%, and marital dissatisfaction was 87%. Data were analyzed using SPSS software and single-variable covariance analysis. The findings showed that resilience training led to an increase in marital compatibility and quality of life and a reduction in marital dissatisfaction among couples seeking divorce.

Abstract
Improving crop yield, quality and water use are crucial in dealing with climate change and water scarcity in arid regions. With the advent of wholly mechanized technology for cotton planting in Xinjiang, it is important to determine the mode with optimizing row configuration, plant density and topping. This study aims to explore the effects of two plant densities, chemical topping vs manual topping under two different common row configurations, i.e. 76 cm equal rows and 10+66 cm narrow-wide rows, which are used for matching harvest machine. The cotton growth, yield, fiber quality and transpiration,were investigated. Experiments were carried out in Xinjiang China, in 2020 and 2021. Seed yield was high in 10 plants m-2 for equal rows and 15 plants m-2for narrow-wide rows. Chemical topping increased fiber length by 2.1% comparing to the traditional manual. Micronaire was 9.6% higher in equal rows than in narrow-wide rows. Under equal row spacing, the WUE in 18 plants m-2 and was 62.4% higher than in 10 plants m-2. Under narrow-wide row spacing, the WUE in 15 plants m-2 was 53.3% higher than in 25 plants m-2. For machine-harvest cotton in Xinjiang, the optimal managements for both high yield and water saving could be 15 plants m-2, narrow-wide rows and applying chemical topping.The results provide a useful approach for optimizing cotton managements and water use.

Abstract
Purpose
To compare the oncological safety of nipple-sparing breast-conserving surgery (BCS) versus central lumpectomy for centrally located breast cancer (CLBC).
Methods
Patients who underwent BCS for CLBC at Asan Medical Center from 2007 to 2018 were reviewed retrospectively. The oncological outcomes of nipple-sparing BCS (NS-BCS) and central lumpectomy were compared using univariate and multivariate Cox regression analyses and compared again after 1:1 propensity score matching (PSM).
Results
The study included 309 patients who underwent NS-BCS and 107 patients who underwent central lumpectomy (median follow-up: 111 months). On multivariate analysis, central lumpectomy had a lower risk of local recurrence compared to NS-BCS, albeit without statistical significance (HR 0.16, 95% CI 0.02–1.23, p = 0.078). There was no significant difference in the risk of death (HR 0.21, 95% CI 0.03–1.70, p = 0.14). After PSM, each group had 107 patients. The 5-year and 10-year local recurrence-free survival rates were 96.2% and 94.8% for NS-BCS, and 99.1% and 99.1% for central lumpectomy, respectively (p = 0.059). There were no significant differences in overall survival, regional recurrence-free survival, or distant recurrence-free survival. Fifteen patients (4.9%) who underwent NS-BCS had ipsilateral breast tumor recurrence (IBTR), of which 40% were in the nipple-areolar complex and previous surgical sites. One patient (0.9%) who underwent central lumpectomy experienced an IBTR in a different quadrant.
Conclusion
NS-BCS showed more local recurrence than central lumpectomy, albeit without statistical significance. When deciding whether to spare the nipple during BCS in CLBC, patients should be sufficiently informed about the risk of IBTR.

Abstract
Background In Southeast Asia, the epidemiological profile of Head and Neck Cancer (HNC) remains under-researched. This study delineates the incidence and subtype-specific burdens of HNC in Ho Chi Minh City, Vietnam (1996–2015).Methods We conducted a population-based retrospective analysis using the Ho Chi Minh City Cancer Registry. The study estimated the 5-year point incidence for four HNC subtypes over 20 years. Age-standardised rates (ASR) were determined using national population metrics. Joinpoint regression analysis was executed to discern patterns over time.Results HNC incidence in Ho Chi Minh City escalated between 1996 and 2015, with nasopharyngeal and oral cancers demonstrating pronounced prevalence. Male diagnoses constituted 73%. The median age of HNC diagnosis in the Vietnamese cohort was approximately a decade earlier than global averages.Conclusions The marked variance in HNC trends in Ho Chi Minh City from global patterns underscores the urgency for implementing effective healthcare strategies in Vietnam.
