Application of Anionic Hydrogels from Date Palm Waste for Dye Adsorption in Wastewater Treatment.

This work aimed to develop an anionic cellulose nanofiber (CNF) bio-adsorbent from date palm tree waste and to investigate its removal efficiency compared to cationic methylene blue dye from contaminated water. Date palm pulp was first prepared from date palm leaves through acid hydrolysis using HSO, followed by hydrolysis in a basic medium using KOH, in which the process completely removed the components of hemicellulose, lignin, and silica. To obtain anionic CNF, the resulting pulp was further treated with HSO, followed by centrifugation.

In Indonesia, the risk of exposure is high due to the inappropriate recycling of used lead batteries. The objective was to investigate the factors that influence lead levels in children's blood.

Repurposing effect of cardiovascular-metabolic drug to increase lifespan: a systematic review of animal studies and current clinical trial progress.

With the increase in life expectancy, aging has emerged as a significant health concern. Due to its various mechanisms of action, cardiometabolic drugs are often repurposed for other indications, including aging. This systematic review analyzed and highlighted the repositioning potential of cardiometabolic drugs to increase lifespan as an aging parameter in animal studies and supplemented by information from current clinical trial registries.

Fluoride Removal Using Nanofiltration-Ranged Polyamide Thin-Film Nanocomposite Membrane Incorporated Titanium Oxide Nanosheets.

Drinking water defluoridation has attracted significant attention in the scientific community, from which membrane technology, by exploring thin film nanocomposite (TFN) membranes, has demonstrated a great potential for treating fluoride-contaminated water. This study investigates the development of a TFN membrane by integrating titanium oxide nanosheets (TiO NSs) into the polyamide (PA) layer using interfacial polymerization. The characterization results suggest that successfully incorporating TiO NSs into the PA layer of the TFN membrane led to a surface with a high negative charge, hydrophilic properties, and a smooth surface at the nanoscale.

IL-6 and IL-10 Levels in Rats Blood Plasma as Immune Responses Post Radioiodine (I-131) Administration.

Objective: The purpose of this study was to analyze the effect of oral administration of radioiodine (I-131) on the immune responses (interleukin 6 and 10) as biodosimetry markers and to support clinical trials of I-131 solution.

Methods: The design of this study was an in vivo experimental study using twenty-seven male rats (Rattus norvegicus strain Sprague-Dawley) given 100 μL of I-131 solution at a dose of 260 μCi. Blood plasma was taken at 0.

Multitemporal analysis of land subsidence induced by open-pit mining activity using improved combined scatterer interferometry with deep learning algorithm optimization.

Mine operational safety is an important aspect of maintaining the operational continuity of a mining area. In this study, we used the InSAR time series to analyze land surface changes using the ICOPS (improved combined scatterers with optimized point scatters) method. This ICOPS method combines persistent scatterers (PS) with distributed scatterers (DS) to increase surface deformation analysis's spatial coverage and quality.

High Proportion of Arsenic Detected in Bronchoalveolar Fluid among Newly Diagnosed Lung Cancer in Jakarta Indonesia.

Objective: This study aims to measure arsenic concentration in bronchoalveolar lavage fluid  (BALF ) of newly diagnosed lung cancer and its corelation with clinical profiles.

Methods: This study is a cross-sectional study to identify arsenic levels in newly diagnosed lung cancer patients. Bronchoalveolar lavage fluid was taken during the bronchoscopy.

The Impact of COVID-19 on Psychological and Social Stigma for Indonesian Nurses: A Cross-Sectional Survey.

Introduction: Nurses are on the front line and are at high risk of experiencing a mental health crisis during the pandemic due to the psychological impact and stigma. The aim of this study was to identify the role of psychological status and social stigma in anxiety, fear, depression, and mental health crises during the pandemic.

Materials And Methods: A cross-sectional design during December 2020-August 2021.

The Tuberculosis and COVID-19 coinfection: A report of two cases at a tertiary referral in Indonesia.

COVID-19 cases are still rising globally in the middle of the tuberculosis epidemic. Several countries have reported TB-COVID-19 coinfection that could pose a double burden in the health care facilities in developing countries. We reported two pulmonary tuberculosis patients coinfected with COVID-19 with an overlapping clinical manifestation of tuberculosis and COVID-19 with a good prognosis at the end of COVID-19 treatment.

TP53 and EGFR Mutational Status in Thymoma: A Genetic Sequencing Study.

Background And Objective: Thymoma is a rare malignant tumor that usually with an indolent presentation, which was falsely assumed to be benign previously. The tumor suppressor P53 (TP53) and EGFR gene mutate most frequently in human cancers. We tried to investigate the presence of TP53 and EGFR mutations among thymoma patients referred to an Indonesian referral respiratory hospital and to discuss its potential role in thymoma management and prognosis.

The effects of luteinizing hormone as a suppression factor for apoptosis in bovine luteal cells in vitro.

The fate of the corpus luteum, a transient endocrine gland formed and degraded during an oestrous cycle, is decided by various physiological factors, such as luteinizing hormone (LH). As a stimulator of progesterone, LH is known to maintain corpus luteum functional and structural integrity by inhibiting apoptosis, a programmed cell death. Therefore, we aim to investigate its action during the mid-luteal phase hypothesized that LH suppresses the death mechanism of bovine luteal steroidogenic cells (LSC) by analysing the expression of proteins involved.

Organically Modified Nanoclay Filled Thin-Film Nanocomposite Membranes for Reverse Osmosis Application.

This study validates, for the first time, the effectiveness of two nanoclays, that is, cloisite (CS)-15A and montmorillonite (MNT) at the polyamide (PA) active layer in the reverse osmosis (RO) membrane. Cloisite-15A is natural montmorillonite modified with dimethyl dihydrogenated tallow quaternary ammonium salt. Thin-film composite (TFC) membranes were fabricated by the interfacial polymerization (IP) process between the trimesoylchloride (TMC)-n-hexane solution and m-phenylenediamine (MPD)-aqueous solution; the IP process took place on a polysulfone support sheet.

Hypoxia-inducible factor 1 mediates hypoxia-enhanced synthesis of progesterone during luteinization of granulosa cells.

Hypoxia has been suggested to enhance progesterone (P4) synthesis in luteinizing granulosa cells (GCs), but the mechanism is unclear. The present study was designed to test the hypothesis that the hypoxia-induced increase in P4 synthesis during luteinization in bovine GCs is mediated by hypoxia-inducible factor 1 (HIF-1). GCs obtained from small antral follicles were cultured with 2 µg/ml insulin in combination with 10 µM forskolin for 24 h as a model of luteinizing GCs.

Hypoxia promotes progesterone synthesis during luteinization in bovine granulosa cells.

To determine whether hypoxia has an effect on luteinization, we examined the influence of hypoxia on a model of bovine luteinizing and non-luteinizing granulosa cell culture. The granulosa cells were obtained from small antral follicles (≤ 6 mm in diameter). To induce luteinization, the cells were treated for 24 h with insulin (2 µg/ml), forskolin (10 µM) or insulin in combination with forskolin at 20% O2.
