Abstract

BACKGROUND: Currently, laboratory diagnosis of intestinal tuberculosis (ITB) is limited based on clinical manifestations, providing opportunities for alternative laboratory tests to diagnose ITB. At the present time, the role of serum adenosine deaminase (ADA) and hematological tests in ITB patients are not widely known. The objective of this study was to determine the role of ADA and hematological tests in patients suspected with ITB.METHODS: Subjects that were suspected of ITB were classified as ITB group, while subjects with inflammatory bowel disease, hemorrhoid, and intestinal malignancy were classified as non-ITB group. Colonoscopy, histopathological examinations, and hematological test were performed. ADA measurement was also performed with clinical chemistry analyzer based on enzymatic colorimetry principle.RESULTS: Out of 143 subjects, 16 (11.2%) subjects were diagnosed with ITB and 127 (88.8%) subjects were classified as non-ITB group. ADA level and erythrocyte sedimentation rate (ESR) of ITB group were significantly higher than the ones of non-ITB group (p<0.05). Cut-off, sensitivity, and specificity of ADA level were 12.56 IU/L, 75%, and 57%, respectively. Cut-off, sensitivity, and specificity of ESR were 32.5 mm/hour, 81%, and 62%, respectively. Colonoscopy of ITB subjects displayed multiple ulcerations, edema, and hyperemic mucosa. Histopathological examination of ITB subjects exhibited granulomatous inflammation, epitheloid cells, giant cells, and lymphocyte aggregates.CONCLUSION: ADA level and ESR were significantly higher among ITB patients compared with non-ITB patients. Since the sensitivities of ADA and ESR tests were high, the ADA and ESR tests could be considered as a screening test for ITB.KEYWORDS: intestinal tuberculosis, adenosine deaminase, hematological tests

Abstract

BACKGROUND: Stem cell culture medium is garnering attention because it comprises growth factors and exosomes secreted by stem cells. In this study, stem cell culture medium was subjected to electric field stimulation using the cells alive system (CAS) to determine the antiaging effects of this medium on dermal fibroblasts.METHODS: The medium was added to the monolayer cultures of human fibroblasts with or without 100 μg/mL advanced glycation end products (AGE), and the cells were incubated for 4 hours. Total RNA was extracted, and mRNA levels of several AGE receptors and heat shock proteins were measured using quantitative reverse transcriptase-polymerase chain rection (qRT-PCR).RESULTS: Similar amounts of exosomes were extracted from the supernatants of stem cells cultured with (CAS+) and without (CAS−) electric field stimulation. The results demonstrated that CAS+ had a higher oxygen radical absorbance capacity than CAS−, indicating its high antioxidant activity. Furthermore, the expression of domain-containing link scavenger receptor-1 mRNA, which is involved in the degradation of cell surface receptors for AGE under glycation stress, significantly increased. The electric field stimulation also increased the expression of several heat shock proteins, which play important roles in cellular responses generated against glycation stress. The electric field stimulation of the stem cell culture medium effectively promoted the endocytosis and degradation of AGE, thereby exerting antioxidant effects and inducing glycation stress.CONCLUSION: Electric field stimulation of stem cell culture medium enhanced the expression of Hsp and its antioxidant activity in fibroblasts.KEYWORDS: AGE, electric field stimulation, exosome, fibroblast, oxygen radical absorbance capacity, stem cell

Abstract

BACKGROUND: Insufficient glucose levels in colorectal cancer (CRC) patients leads to a condition where fructose might become an alternative source for cells proliferation, but the role of fructose or fructose-glucose combinations in development of CRC has not been elucidated well. In this study, the effect of fructose-glucose variations on viability, migration, and glucose transporter (GLUT)5, GLUT7, GLUT11 mRNA expressions in WiDr CRC cell line were examined.METHODS: Cells were treated with varying ratios of fructose-glucose (F100%; F75%:G25%; F50%:G50%; F25%:G75%; G100%; F: Fructose, G: Glucose). Untreated cells (F0:G0) were used as cell control. The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay was used for cell viability test, scratch assay was used to examine the cell migration, and quantitative polymerase chain reaction (qPCR) was performed to examine mRNA expressions. Data were analyzed using one-way analysis of variance (ANOVA) and followed with Tukey's post-hoc test, with p<0.05 consideres as significant.RESULTS: Fructose-glucose combinations and glucose 100% significantly increased the cell viability compared to control (p<0.05). All treatment groups showed a significant increase in cell migration compared to control (p=0.000). Only GLUT7 and GLUT11 expressions in the G100% group were significantly different compared to the control (p=0.000). GLUT7 and GLUT11 expressions were also significantly different in F100% and F50%:G50% treatments compared to G100% (p=0.000).CONCLUSION: Taken together, fructose might play important role in cell migration. However, in cell viability, combination with glucose could increase fructose's effect. Fructose might not affect the mRNA expressions of GLUT5, GLUT7 and GLUT11.KEYWORDS: GLUT5, GLUT7, GLUT11, fructose transporter, colorectal cancer, WiDr

Abstract

BACKGROUND: Exclusive breastfeeding could be a protective step to avoid infant stunting. During lactation, several hormones are involved in milk secretion, including insulin. Polyscias scutellaria is a perennial plant which has traditionally been used to increase breast milk production. This study was conducted to examine the impact of P. scutellaria leaf extract on the mammary gland histology, expression of insulin in the mammary gland, as well as plasma insulin and the insulin receptor levels.METHODS: Five female unmated rats (UR) and twenty female lactating rats were divided into five groups, namely UR, lactating rats only (LRO), lactating rats treated with Asifit (LRA), lactating rats treated with PSAE at a dosage of 250 and 500 mg/kg body weight (BW) (LRPSAE 250 and 500). Treatments were given orally for 14 days. The dams were sacrificed after the weaning stage (third week after parturition), and the serum, mammary gland, liver, and muscle were collected for further analysis.RESULTS: The histoarchitecture of mammary gland between the LRA and LRPSAE groups were similar. The LRPSAE 250 group had higher plasma level and immunofluorescent expression of insulin than the LRA group. PSAE did not affect insulin receptor beta subunit (INSR-β) levels in both liver and muscle of lactating rats.CONCLUSION: PSAE could be used as an herbal treatment to increase breast milk production by improving mammary gland histology and maintaining the mother's insulin levels.KEYWORDS: Polyscias scutellaria, lactating rats, insulin, INSR-β

Abstract

BACKGROUND: Emergence of drug resistance due to epidermal growth factor receptor (EGFR) Exon 20 T790M poses a challenge in the effective management of non-small cell lung carcinoma (NSCLC). Significant breakthrough in the management of NSCLC with a specific genetic alteration causes substantial condition improvement in patients whose cancer progressed after first-generation tyrosine kinase inhibitor treatment and who developed tumors with EGFR Exon 20 T790M mutation. The present study analyzed a cohort of NSCLC patients and investigated the incidence of the EGFR Exon 20 T790M status with Osimertinib therapy, along with its impact on survival rates.METHODS: This was a retrospective cohort study on 22 NSCLC subjects who were genetically examined for EGFR status from plasmic cell free total nucleic acid. Subjects with EGFR Exon 20 T790M mutation were treated with/without Osimertinib. Demographic and clinical data were descriptively summarized, and the differences of each variable and correlation between survival rate and EGFR Exon 20 T790M were analyzed.RESULTS: Subjects with (n=13) and without (n=9) EGFR Exon 20 T790M had survival rates of 10.77±2.45 and 4.78±1.48, respectively (p=0.000). Based on 1-year survival status of subjects with EGFR Exon 20 T790M, there were 3 Osimertinib-treated survivors and 2 Osimertinib-treated non-survivors. Eight subjects with EGFR Exon 20 T790M and without Osimertinib treatment did not survive (p=0.001).CONCLUSION: Since the treatment of Osimertinib demonstrated a noteworthy survival rate among NSCLC subjects with EGFR Exon 20 T790M, thus Osimertinib could be suggested as a potential targeted therapy for NSCLC subjects with EGFR Exon 20 T790M.KEYWORDS: non-small cell lung carcinoma, EGFR, Exon 20, T790M, osimertinib

Abstract

BACKGROUND: Dendritic cell (DC)-based cancer therapy is a promising adjuvant therapy for nasopharyngeal cancer (NPC) after chemoradiation. Owing to low immunity after chemoradiation, DC therapy activates immune responses. Moreover, DC-based cancer therapy can decrease tumor progression, prolong lifespan, and increase the quality of life of patients. Various studies regarding the use of DC therapy for NPC have been reported, however there are limited reviews on the implementation and foundation of DC immunotherapy to expand this technology.METHODS: A literature search was performed on EMBASE, ScienceDirect, PubMed (MEDLINE), and Cochrane Library, with the term dendritic cells therapy for nasopharyngeal cancer, dendritic cell immunotherapy in nasopharyngeal cancer patients, and DC therapy in NPC, as the search keywords.RESULTS: A total of 199 literatures were reviewed, and four clinical trials were identified as relevant for this review. DC vaccines can be processed with various maturation and activation processes. Selected literatures reported antigens used when incubating the DC are latent membrane protein (LMP) 1, LMP2, and Epstein–Barr virus nuclear antigen 1 (EBNA1). Although DC therapy was produced from different pathways, it has been reported that there are increases of cluster of differentiation (CD)8+ T cells, CD4+ T cells, and the progression free survival (PFS) rate in DC immunotherapy patients than the radiochemotherapy patients.CONCLUSION: It can be concluded that DC could be used as an adjuvant therapy alongside the standard therapy of NPC, which prolongs NPC patient survival.KEYWORDS: adjuvant cell therapy, nasopharyngeal cancer therapy, dendritic cells

Abstract

BACKGROUND: Breast Cancer (BC) and thyroid dysfunction are commonly observed ailments in females, and two may occur synchronously. The present study was conducted to find the role of oxidative stress and its association with thyroid dysfunction and BC.METHODS: In this cross-sectional study, 288 and 100 subjects were included in case and control groups, respectively. Serum samples were obtained from consented subjects. Thyroid profile, thyroid antibodies, antioxidant and oxidant profiles, as well as cathepsin S (CTSS), prolactin, and estradiol levels were estimated using specific enzyme-linked immunosorbent assay kits. The data was analyzed using independent Student's t-test and Pearson correlation test.RESULTS: BC cases had higher levels of thyroid antibodies and thyroid stimulating hormone than controls. Prolactin and estradiol levels were also deranged in the case group. Higher oxidative stress biomarkers were evident in the case group; 8-hydroxy-2'-deoxyguanosine (8-OHdG), a DNA damage marker, increased concomitantly. Correlation analysis showed a positive correlation between the antioxidant (catalase) and the oxidant (8-OHdG) levels. Furthermore, the higher level of CTSS in BC cases than in the controls is the hallmark of this study, demonstrating the pathogenesis and progression of the disease.CONCLUSION: Results suggest the mediating role of oxidative stress in the association between thyroid dysfunction and BC. It concludes that the parameters assessed in this study could be indicative of disease progression and metastasis in BC as well as thyroid dysfunction.KEYWORDS: breast cancer, thyroid, oxidant, antioxidant, ROS

Abstract

BACKGROUND: High angiotensin-converting enzyme 2 (ACE2) expression in adipocyte cells facilitates the initiation of SARS-CoV-2 infection and triggers a cytokine storm. This finding suggests that obesity is an independent risk factor for the severity of the symptoms caused by COVID-19. The use of cardiovascular medications that focus on ACE2, such as angiotensin II receptor blockers, remains controversial, and their effects on inflammatory cytokine production and ACE2 expression in cells, especially adipocytes, remain inconsistent.METHODS: The human adipocytes were isolated from obese donor subcutaneous adipose tissue and infected with the subunit S1 spike protein from SARS-Cov-2. The adipocytes were later treated with either hrsACE2 or losartan. The levels of ACE2 and inflammatory cytokines interleukin (IL)-6, IL-1β, and tumor necrosis factor (TNF)-α were measured using enzyme linked immunosorbent assay (ELISA). ACE2 and S1 spike protein binding assays were also performed. RESULTS: ACE2, IL-6, and TNF-α levels were significantly increased in human adipocyte cells infected with SARS-Cov-2 but not IL-1β. There was a statistically significant positive correlation between ACE2 and IL-6 (r=0.878, p<0.001). Administration of losartan and hrsACE2 was shown to reduce ACE2 levels and its binding to the SARS-CoV-2 S1 spike protein, and IL-6 levels were statistically significant, but had no significant effect on IL-1β or TNF-α levels.CONCLUSION: This study shows that the administration of losartan in COVID-19 may not be harmful, but instead has a protective effect similar to that of hrsACE2 in preventing a cytokine storm, especially IL-6.KEYWORDS: obesity, SARS-CoV-2, losartan, IL-6, ACE2

Abstract

BACKGROUND: Lipopolysaccharide (LPS) has been reported to increase CD4+ regulatory T-cell (CD4+ Treg) populations. Acetylsalicylic acid (ASA) has been reported to have immunomodulatory activity, but it may induce chronic gastric ulceration. Another salicylic acid-bearing compound, 2-(3-(chloromethyl)benzoyloxy)benzoic acid (3-CH2Cl), has been reported to have less gastric mucosal damage. However, the effect of 3-CH2Cl on CD4+ Tregs in LPS-induced mice is still unknown. Therefore, the present study was conducted to investigate the immunomodulatory effect of 3-CH2Cl on CD4+ T-cell and CD4+ Treg populations as well as FoxP3 expression in LPS-induced mice.METHODS: Synthesis of 3-CH2Cl was performed by mixing salicylic acid and chloromethylbenzoylchloride with the catalyzation of pyridine, acetone and heat. The 3-CH2Cl tablets were prepared using direct compression method. After intraperitoneal injection of 1 mg/kg BW LPS to mice, 60 mg/kg BW ASA or 60 mg/kg BW 3-CH2Cl was given orally for 3 days. The splenocyte was obtained through splenectomy and collagenase digestion. The population of CD4+ T-cells and CD4+ Tregs, as well as the splenic FoxP3 expression were determined using flow cytometry technique.RESULTS: CD4+ T-cell populations in mice treated with LPS and 3-CH2Cl or ASA were lower than those treated with LPS merely. Meanwhile, CD4+ Treg populations and FoxP3 expression levels in mice treated with LPS and 3-CH2Cl or ASA were higher than those treated with LPS merely.CONCLUSION: Since 3-CH2Cl could decrease CD4+ T-cell population and increase CD4+ Treg population mediated by the increase of FoxP3 expression in LPS-induced inflammation, it may act as a potential therapeutic drug to reduce inflammatory conditions.KEYWORDS: 2-(3-(chloromethyl)benzoyloxy)benzoic acid, acetylsalicylic acid, CD4, T-regulatory cells, FoxP3, LPS

Abstract

BACKGROUND: Extended-spectrum β-lactamase-producing Escherichia coli (ESBL-EC) are selectively proliferated in the human gut, excreted through feces, and deposited through wastewater lines, with hospital wastewater acting as a major reservoir of antibiotic resistance genes and resistant bacteria, thus pose adverse effects to human health. This study aimed to determine the presence of blaCTXM-1, blaCTXM-9, blaTEM-1, and blaSHV-1 genes in ESBL-EC in wastewater from selected hospitals in Manila and Quezon City, the Philippines.METHODS: Influent and effluent in twelve hospital wastewater treatment plants were collected, screened for cefotaxime-resistant E. coli, and examined for the ESBL production through phenotypic characterization using conventional bacterial identification, disk diffusion method, and VITEK® 2 Compact system and genotypic identification of ESBL-EC blaCTXM-1, blaCTXM-9, blaTEM-1, blaSHV-1 genes using multiplex polymerase chain reaction (PCR).RESULTS: Conventional bacterial identification methods and the VITEK® 2 Compact system results showed that both influent and effluent samples were positive for ESBL-EC at 33.3% and 16.7%, respectively. Multiplex PCR results revealed that various E. coli isolates were of ESBL-EC blaCTXM-1, blaCTXM-9, and blaTEM-1 genes. Multi-drug resistance was observed among all ESBL-EC isolates with resistance being highest against ampicillin, cefuroxime, ceftazidime, ceftriaxone, cefepime, piperacillin, and aztreonam.CONCLUSION: As the study revealed the presence of ESBL-producing bacteria, efforts must be made to ensure the prudent antimicrobial use with possible emphasis on antibiotic rotation accompanied by intensified infection prevention and control in hospital settings.KEYWORDS: antimicrobial resistance, beta-lactams, blaCTXM, blaTEM, extended-spectrum beta-lactamase, E. coli, hospital wastewater
