Abstract

ABSTRACT Antisperm antibody (ASA) is one of the immunological factors that play a role in unexplained infertility. About 10-30% of infertile couples are caused by ASA. ASA is thought to be lowered by paternal lymphocyte immunization (PLI), but the immune mechanism that occurs in the body is unclear. This research aims to understand the immune mechanism after PLI in women with unexplained infertility by analyzed ASA, IFNγ, IDO, and Treg cells populations. This research using observational analysis, conducted in X Jakarta Hospital from June 2018 to April 2019. Samples were 12 unexplained infertility women with ASA>1:128. Samples were examined ASA titers using the husband's sperm auto-agglutination test (HSAaT) method. Tregs were evaluated using flow cytometry. IFNγ and IDO was determined using an ELISA. The data were analyzed using the Mann-Whitney and Spearman tests. Results show that PLI can reduce ASA. Treg cells percentage ratio increased after 3 times PLI by 20% and 6 times PLI by 50%, but the increase was not significant. An increase of high IFNγ is followed by an increase in the IDO ratio post/early research and an increase in the percentage of the Treg cell population. The results of this study can be considered as a diagnostic use as well as one of the benchmarks in identifying unexplained causes of infertility, IVF failure, and increasing the success of IVF, can also be used as a prognostic for pregnancies with a history of recurrent miscarriage so that subsequent pregnancies are better. ABSTRAK Antibodi antisperma (ASA) merupakan salah satu faktor imunologi yang berperan pada infertilitas yang tidak terjelaskan. Sekitar 10-30% pasangan infertil disebabkan oleh ASA. ASA diduga dapat diturunkan dengan paternal lymphocyte immunization (PLI), namun mekanisme imun yang terjadi di dalam tubuh belum jelas. Penelitian ini bertujuan untuk mengetahui mekanisme imun pada perempuan infertilitas yang tidak terjelaskan setelah diberikan PLI melalui analisis ASA, IFNγ, IDO, dan populasi sel Treg. Desain penelitian adalah observasional analitik. Penelitian dilakukan di RS X Jakarta dari Juni 2018 sampai dengan April 2019. Sampel sejumlah 12 perempuan infertilitas tidak terjelaskan dengan ASA >1:128. Pengukuran ASA menggunakan metode husband's sperm auto-agglutination test (HSAaT). Populasi sel Treg diukur dengan flowsitometer. IFNγ dan IDO diukur menggunakan ELISA. Data dianalisis menggunakan uji Mann-Whitney dan Spearman. Hasil penelitian didapatkan bahwa PLI dapat menurunkan ASA. Rasio persentase sel Treg meningkat setelah 3 kali PLI sebesar 20% dan 6 kali PLI sebesar 50%, namun kenaikan tesebut tidak bermakna. Kenaikan IFNγ yang tinggi diikuti oleh kenaikan rasio IDO post/pre dan kenaikan persentase populasi sel Treg. Hasil penelitian ini dapat dipertimbangkan sebagai penggunaan diagnostik, salah satu tolok ukur dalam mengidentifikasi penyebab infertilitas yang tidak terjelaskan, meningkatkan keberhasilan IVF, serta digunakan sebagai prognostik kehamilan dengan riwayat keguguran berulang agar kehamilan berikutnya menjadi lebih baik.

Abstract

Latar belakang: Otak memerlukan oksigen yang banyak selain glukosa. Hipoksia iskemik karena strok hemoragik atau Spontaneous intracerebral hemorrhage (sICH) dapat mengganggu suplai oksigen dan nutrisi ke otak berakibat produksi energi di otak akan menurun. Deplesi energi ini menyebabkan kerusakan dan kematian sel otak terjadi lebih cepat. Neuroglobin (Ngb) dan sitoglobin (Cygb) merupakan protein golongan globin yang terdapat di otak dan berperan sebagai protein pengikat oksigen di mitokondria. Tujuan: Penelitian ini bertujuan mendapatkan gambaran/profil kadar Ngb dan Cygb, di plasma, cairan serebro spinal (CSS), dan jaringan otak pasien strok hemoragik. Metode: Penelitian ini merupakan penelitian lanjutan menggunakan sampel plasma, CSS, dan jaringan otak yang diperoleh saat kraniotomi evakuasi hematoma pasien strok hemoragik sICH di rumah sakit Cipto Mangunkusumo dan rumah sakit lainnya di Jakarta. Kadar protein Ngb dan Cygb dari plasma, CSS, dan jaringan otak diukur dengan metode ELISA. Hasil: Rerata kadar Ngb otak adalah 0,058 ng/mg protein otak, sedangkan di plasma dan CSS masing-masing adalah 0,017 ng/mg protein otak dan 0,013 ng/mg protein otak atau 29,31% dan 22,41% dari rerata kadar Ngb otak. Rerata kadar Cygb otak adalah 4,943 ng/mg protein otak, di CSS adalah 1,685 ng/mg protein otak, atau 25,26% dari rerata Cygb otak, sedangkan di dalam plasma hampir tidak terdeteksi. Simpulan: Pada keadaan hipoksia oleh karena strok hemoragik sICH, protein Ngb dan Cygb dapat diukur di plasma, CSS, dan jaringan otaknya.

Abstract

ABSTRACT. Folate binding protein (FBP) is a protein in breast milk that plays a role in the regulation and bioavailability of folic acid. In contrast to cow's milk FBP, information about breast milk FBP is still limited. This research aims to determine the isolation and purification methods of breast milk FBP and the molecular weight of breast milk FBP. The sample in this study was 1000 mL of breast milk. Breast milk was prepared in several stages to yield whey. Isolation and purification of FBP from whey were carried out in stages, salting-out, ion exchange chromatography, and affinity chromatography. Whey salting-out with 95% saturation of ammonium sulfate could precipitate folate-binding proteins. This precipitate showed three peaks on DEAE chromatography. Peak II DEAE 95% was thought to be a negatively charged folate-binding protein. Peak II DEAE 95% also showed the presence of two peaks on affinity chromatography. It was believed that Peak II AF 95% was a pure folate-binding protein. Peak II AF 95% showed the presence of a single band on SDS-PAGE and western blot. This indicated that the folate-binding protein was 100% pure. FBP can be isolated from breast milk by the salting-out method using 95% ammonium sulfate, DEAE chromatography, and affinity chromatography. FBP from breast milk has a molecular weight of approximately 37 kDa. The final level of FBP isolated from breast milk is approximately 0.022 mg/mL. The successful isolation of FBP from breast milk provides an opportunity to use it to understand the clinical role of FBP in increasing folic acid levels in both breast milk and infant serum, as well as to develop methods for determining folic acid levels in these fluids. Keywords: Breast milk, folate binding protein, isolation, purification, molecular weight

Abstract

BACKGROUND: Stunting due to malnutrition and soil-transmitted helminth (STH) chronic infections can cause disturbances in bone formation processes during growth. Reduced levels of insulin-like growth factor 1 (IGF-1) lead to reduced osteoblast activity which can be monitored through alkaline phosphatase (ALP) and osteocalcin (OCN). Unfortunately, studies that assessed IGF-1, OCN, and ALP together in stunted children with STH infection are still limited. Therefore, in this study, the osteoblast activity was monitored by measuring IGF-1, OCN, and ALP in stunted and normo-stature children with STH infection.METHODS: A case-control study involving 28 stunted and 33 normal-stature children was conducted. Blood plasma IGF-1 and OCN levels were measured using the enzyme linked immunosorbent assay (ELISA) method, while ALP activity was measured using the colorimetric method. STH infection was examined by direct smear method. The parameters were analyzed and compared between the stunted and normo-stature children.RESULTS: Although in stunted boys there was no significant difference, however in stunted girls with positive STH infection, a decrease in IGF-1 (<36.60 ng/mL vs. ≥36.60 ng/mL) showed an impact on the decrease of OCN levels (54.68 (42.22-144.54) ng/mL vs. 104.55 (86.14-392.73) ng/mL; p=0.047). ALP activity in children with positive STH infection showed that ALP activity in stunted children was lower than in normo-stature children (18 (10-671) U/L vs. 228.50 (16-574) U/L; p=0.005).CONCLUSION: The blood levels of IGF-1 and ALP activity in stunted and positive STH infected children tend to be lower than in normo-stature children.KEYWORDS: stunted, normo-stature, IGF-1, bone alkaline phosphatase, osteocalcin

Abstract

BACKGROUND: Hypoxia inducible factor-1α (HIF-1α), nuclear factor erythroid 2-related factor 2 (Nrf-2), and vascular endothelial growth factor (VEGF), play a crucial role as neuroprotective factors. Currently, there is a lack of studies examining the biomolecular responses of the brain to intermittent hypoxia resulting from various pressures. This study was conducted to investigate the physiological responses, histopathological features, and cellular adaptive responses in the brains of rats that were intermittently exposed to hypobaric hypoxic conditions.METHODS: Thirty male Sprague Dawley rats were divided into six groups: a control group and five treatment groups exposed to hypobaric hypoxia. The treatment groups were placed in a hypobaric chamber simulating an altitude of 3,048 meters for 1 hour/day for 1, 7, 14, 21, and 28 days. After exposure, brain tissue was collected for histopathological analysis and protein quantification of HIF-1α, Nrf-2, cytoglobin (Cygb), neuroglobin (Ngb), VEGF, malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT).RESULTS: In the brain, intermittent hypobaric hypoxia significantly increased HIF-1α expression (p=0.000) and its downstream proteins Cygb (p=0.000), and VEGF (p=0.001), with a peak at 14x IHH exposure compared to control. This was followed by a significant increase in Nrf-2 expression (p=0.000), SOD (p=0.000), Gpx (p=0.000), and CAT activity (p=0.000), indicating an adaptive antioxidant response. Conversely, MDA levels was decreased with prolonged exposure, suggesting reduced oxidative damage.CONCLUSION: IHH elevates HIF-1α, Nrf-2, and oxidative stress markers, triggering an adaptive antioxidant response in the rat’s brains.KEYWORDS: HIF-1α, intermittent hypobaric hypoxia, Nrf-2, oxidative stress

Abstract

Hyperbaric oxygen therapy (HBOT) has gained increasing attention as a potential adjunctive treatment for traumatic brain injury (TBI) patients. This narrative review discusses the historical background, current preclinical and clinical studies, and explores its underlying mechanisms from biomolecular, histological, and clinical perspectives. HBOT promotes neural recovery by improving oxygenation, preserving mitochondrial integrity, enhancing neurotrophic support and synaptic connectivity, mitigating secondary injury pathways (including oxidative stress, inflammation, and apoptosis), and promoting angiogenesis and vascular stability. These mechanisms have demonstrated improvements of motor, cognitive, and memory functions both in preclinical and clinical studies, although outcomes and treatment protocols vary. However, challenges remain regarding optimal protocols, patient selection, and adverse effects. Further high-quality clinical trials are required to define the optimal HBOT regimen are required.

Abstract

The results of the Immunochromatographic Method for Infectious Disease Testing (IMLTD) may vary depending on the presence of lipids in donor blood samples, potentially leading to false‐negative or false‐positive outcomes in hepatitis B surface antigen (HBsAg) screening. This study aimed to evaluate the effect of lipid interference on HBsAg screening using the chemiluminescent immunoassay (CLIA) method, to determine the range of triglyceride levels that may influence test results (100 mg/dL to >3000 mg/dL), and to assess practical lipid removal methods to ensure blood safety. An experimental laboratory study was conducted using two sample groups. The first group consisted of six bags of non-lipemic, HBsAg-reactive plasma that were rendered lipemic by the addition of Lipofundin. The second group included 25 bags of lipemic donor plasma that were non-reactive in the initial IMLTD screening and subsequently subjected to lipid removal treatments. Lipid reduction was performed using centrifugation, polyethylene glycol (PEG), and diethyl ether. The results showed no significant differences in HBsAg values before and after Lipofundin addition, indicating that lipemia did not affect HBsAg detection by the CLIA method. However, lipid removal using centrifugation, PEG, and diethyl ether significantly reduced triglyceride and total cholesterol levels (p < 0.05) in lipemic samples that interfered with CLIA analysis. In conclusion, lipemia does not directly affect HBsAg screening results using the CLIA method; however, lipid removal procedures are effective and necessary for managing highly lipemic samples to maintain the accuracy and reliability of blood screening tests.

Abstract

Waste management in South Tangerang City has become an increasingly complex environmental issue along with population growth and urbanization. Although various regulations are already in place, such as Law Number 18 of 2008 and related regional regulations, the implementation of waste management policies still faces numerous challenges, including issues related to legal substance, law enforcement structure, and the legal culture of the community. This Community Service Program (PKM) aims to analyze the implementation of waste management policies from an environmental law perspective and to evaluate the effectiveness of law enforcement in South Tangerang City. The method used is a normative-empirical approach, with activities including seminars, interactive discussions, and workshops involving the community and stakeholders. The findings indicate a gap between preventive regulations and the reality in the field, which remains largely reactive. The main factors contributing to the low effectiveness of law enforcement include limited facilities and infrastructure, weak supervision, and low public awareness regarding waste management. Through this activity, it is expected that public understanding of the importance of environmentally based waste management will increase, along with greater active participation in preserving environmental sustainability. In addition, strengthening derivative regulations, optimizing law enforcement, and implementing technology-based and community-based waste management systems are necessary to achieve effective and sustainable waste management.

Abstract

Background: Carbonic anhydrase (CA) regulates intracellular CO₂/HCO₃⁻ homeostasis and supplies carboxyl donors for the sixth step of de novo purine biosynthesis. Disruption of this step is predicted to impair nucleotide pool accumulation and arrest cell cycle progression. Objective: This study investigated whether CA inhibition by acetazolamide suppresses T lymphocyte proliferation. Methods: Human peripheral blood mononuclear cells (PBMCs) were stimulated with phytohemagglutinin (PHA, 1% v/v) or interleukin-2 (IL-2, 10 ng/mL). Acetazolamide was applied at 6.25–50 μM. Cell viability, DNA synthesis, and cell cycle distribution were assessed using WST-1 assay, BrdU incorporation, and propidium iodide flow cytometry, respectively. Results: Acetazolamide reduced PBMC viability and DNA synthesis dose-dependently in both PHA- and IL-2-stimulated cultures (p < 0.05). IL-2-stimulated cells showed greater sensitivity, with significant inhibition at 12.5 μM versus 25 μM for PHA-stimulated cells. Flow cytometry revealed G1/S arrest in all treated groups: S phase decreased from 8.52% to 3.82% (PHA) and from 1.27% to 0% (IL-2) at 50 μM, with G2/M uniformly suppressed to ≤0.57%. Conclusion: Acetazolamide suppresses PBMC proliferation through G1/S arrest, consistent with CA inhibition depleting CO₂/HCO₃⁻-dependent carboxyl donors required for de novo purine synthesis.

Abstract

Background: Although convalescent plasma contains neutralizing anti-SARS-CoV-2 antibodies, co-existing inflammatory mediators pose safety risks in critically ill recipients. Purified IgG preparations offer a safer alternative by concentrating therapeutic antibodies while eliminating these harmful components. Objective: To establish a systematic protocol for purifying total IgG from SARS-CoV-2 convalescent serum using sequential chromatographic techniques. Methods: Serum from 90 RT-PCR-confirmed recovered donors was pooled into three independent samples. Purification employed four sequential steps: ammonium sulfate precipitation (50% saturation), Sephadex G-100 size-exclusion chromatography, DEAE-Cellulose ion-exchange chromatography, and Protein A affinity chromatography. Purity and identity of IgG fractions were assessed by native polyacrylamide gel electrophoresis and radial immunodiffusion. Results: Starting from serum containing 19.68 ± 7.27 mg/mL IgG and 110.47 ± 11.99 mg/mL total protein, the four-step purification yielded a final IgG concentration of 1.14 ± 0.70 mg/mL with total protein of 1.19 ± 0.16 mg/mL, representing 6.3-fold purification with a final IgG-to-total protein purity ratio of 1.01 ± 0.38 and an overall recovery of 5.8%. Native PAGE confirmed high purity with a single dominant IgG band. Conclusion: Sequential chromatography yielded near-homogeneous IgG from SARS-CoV-2 convalescent serum, offering a laboratory-scale approach for preparing safer immunoglobulin therapeutics.
