RESUMO

INTRODUCTION: Inflammation is a fundamental response to various insults, including microbial invasion and tissue injury. While aspirin (ASA) has been widely used for its anti-inflammatory properties, its adverse effects and limitations highlight the need for novel therapeutic alternatives. Recently, a novel salicylic acid derivative, 2-((3-(chloromethyl)benzoyl)oxy)benzoic acid (3-CH2Cl), has emerged as a potential substitute for ASA, offering a simpler, environmentally friendly synthesis and a promising safety profile. AIM OF THE STUDY: This research aims to evaluate the anti-inflammatory mechanism of 3-CH2Cl in a lipopolysaccharide (LPS)-induced mouse model, focusing on its effects on prostaglandin E-2 (PGE-2) concentration, NOX2 and NFkB expression, ROS production, and COX-2 expression. MATERIAL AND METHODS: Utilizing BALB/C mice subjected to LPS-induced inflammation, we investigated the therapeutic potential of 3-CH2Cl. The study included synthesis and tablet preparation, experimental design, peripheral blood plasma PGE-2 measurement, splenocyte isolation and COX-2 expression analysis, nitric oxide and ROS measurement, and immunohistochemical analysis of NOX2 and NFkB expression. RESULTS: 3-CH2Cl significantly reduced PGE-2 levels (p=0.005), NO concentration in liver homogenates (p=0.005) and plasma (p=0.0011), and expression of NOX2 and NFkB in liver (p<0.0001) and splenocytes (p=0.0036), demonstrating superior anti-inflammatory activity compared to ASA. Additionally, it showed potential in decreasing COX-2 expression in splenocytes. CONCLUSION: 3-CH2Cl exhibits potent anti-inflammatory properties, outperforming ASA in several key inflammatory markers in an LPS-induced inflammation model. The reduction of COX-2 expression, alongside the reduction of pro-inflammatory cytokines and oxidative stress markers, suggest it as a promising therapeutic agent for various inflammatory conditions.

RESUMO

INTRODUCTION: Salicylic acid derivate is very popular for its activity to suppress pain, fever, and inflammation. One of its derivatives is acetylsalicylic acid (ASA) which has been reported repeatedly that, as a non-steroidal anti-inflammatory drug (NSAID), it has a cardioprotective effect. Although ASA has various advantages, several studies have reported that it may induce severe peptic ulcer disease. We recently synthesized a new compound derived from salicylic acid, namely 2-((3-(chloromethyl)benzoyl)oxy)benzoic acid (3-CH2Cl) which still has the benefit of acetylsalicylic acid as an analgesic and antiplatelet, but lacks its harmful side effects (Caroline et al., 2019). In addition, in silico studies of 3-CH2Cl showed a higher affinity towards protein receptor cyclooxygenase-2 (COX-2; PDB: 5F1A) than ASA. We hypothesized that 3-CH2Cl inhibits the COX-2 activity which could presumably decrease the inflammatory responses. However, no knowledge is available on the anti-inflammatory response and molecular signaling of this new compound. Hence, in this study, we investigated the potential functional relevance of 3-CH2Cl in regulating the inflammatory response in lipopolysaccharide (LPS)-induced rats. The results of this study show that this compound could significantly reduce the inflammatory parameter in LPS-induced rats. MATERIAL AND METHODS: Rats were induced with LPS of 0.5 mg/kg bw intravenously, prior oral administration with vehicle (3% Pulvis Gummi Arabicum / PGA), 500 mg/60 kg body weight (bw; rat dosage converted to human) of 3-CH2Cl and ASA. The inflammatory parameters such as changes in the temperature of septic shock, cardiac blood plasma concentrations of IL-1ß and TNF-α (ELISA), blood inflammation parameters, white blood cell concentrations, and lung histopathology were observed. Meanwhile, the stability of 3-CH2Cl powder was evaluated. RESULT: After the administration of 500 mg/60 kg bw of 3-CH2Cl (rat dosage converted to human) to LPS-induced rats, we observed a significant reduction of both TNF-α (5.70+/-1.04 × 103 pg/mL, p=<0.001) and IL-1ß (2.32+/-0.28 × 103 pg/mL, p=<0.001) cardiac blood plasma concentrations. Besides, we found a reduction of white blood cell concentration and the severity of lung injury in the 3-CH2Cl group compared to the LPS-induced rat group. Additionally, this compound maintained the rat body temperature within normal limits during inflammation, preventing the rats to undergo septic shock, characterized by hypothermic (t = 120 min.) or hyperthermic (t = 360 min) conditions. Furthermore, 3-CH2Cl was found to be stable until 3 years at 25°C with a relative humidity of 75 ± 5%. CONCLUSION: 3-CH2Cl compound inhibited inflammation in the LPS-induced inflammation response model in rats, hypothetically through binding to COX-2, and presumably inhibited LPS-induced NF-κß signaling pathways. This study could be used as a preliminary hint to investigate the target molecular pathways of 3-CH2Cl as a novel and less toxic therapeutical agent in alleviating the COX-related inflammatory diseases, and most importantly to support the planning and development of clinical trial.

RESUMO

Prostate carcinoma and benign prostate hyperplasia (BPH) with associated lower urinary tract symptoms (LUTS) are among the most prevalent and clinically relevant diseases in men. BPH is characterized by an enlargement of prostate tissue associated with increased tone of smooth muscle cells (SMCs) which surround the single glands composing the prostate. Secretions of the glands leave the prostate through local excretory ducts during the emission phase of ejaculation. Pharmacological treatment of BPH suggests different local drug targets based on reduction of prostate smooth muscle tone as the main effect and disturbed ejaculation as a common side effect. This highlights the need for detailed investigation of single prostate glands and ducts. We combined structural and functional imaging techniques-notably, clear lipid-exchanged, acrylamide-hybridized rigid imaging/immunostaining/ in situ hybridization-compatible tissue-hydrogel (CLARITY) and time-lapse imaging-and defined glands and ducts as distinct SMC compartments in human and rat prostate tissue. The single glands of the prostate (comprising the secretory part) are characterized by spontaneous contractions mediated by the surrounding SMCs, whereas the ducts (excretory part) are quiescent. In both SMC compartments, phosphodiesterase (PDE)-5 is expressed. PDE5 inhibitors have recently emerged as alternative treatment options for BPH. We directly visualized that the PDE5 inhibitors sildenafil and tadalafil act by reducing spontaneous contractility of the glands, thereby reducing the muscle tone of the organ. In contrast, the ductal (excretory) system and thus the prostate's contribution to ejaculation is unaffected by PDE5 inhibitors. Our differentiated imaging approach reveals new details about prostate function and local drug actions and thus may support clinical management of BPH.-Kügler, R., Mietens, A., Seidensticker, M., Tasch, S., Wagenlehner, F. M., Kaschtanow, A., Tjahjono, Y., Tomczyk, C. U., Beyer, D., Risbridger, G. P., Exintaris, B., Ellem, S. J., Middendorff, R. Novel imaging of the prostate reveals spontaneous gland contraction and excretory duct quiescence together with different drug effects.

RESUMO

Acetylsalicylic acid is used as a non-steroidal anti-inflammatory drugs (NSAID) and antiplatelet agents by inhibiting cyclooxygenases. However, therapy using acetylsalicylic acid could induce gastric bleeding and cause other gastrointestinal toxicity. The aim of this study was to demonstrate the synthesis of a new compound bearing salicylic acid residue namely 2-((3-(chloromethyl)benzoyl)oxy)benzoic acid, to analyze its potential as a ligand for human cyclooxygenase-2 (COX-2) receptor, to evaluate its toxicity level and its effectiveness for analgesic and antiplatelet agent compared with acetylsalicylic acid. Synthesis of 2-((3-(chloromethyl)benzoyl)oxy)benzoic acid was conducted by microwave irradiation. The purity of this compound was evaluated with TLC, IR, NMR, and EDS spectroscopy. The chemical characterization and docking studies against human COX-2 (PDB:5F1A) was performed in-silico. The acute oral toxicity assay was performed under OECD guidelines. The analgesic activity study was performed by plantar and writhing test on animal model. For anti-platelet activity study, we performed tail-bleeding assay and flow cytometry based platelet aggregation assay. We could successfully synthesize a pure white crystalline 2-((3-(chloromethyl)benzoyl)oxy)benzoic acid. In-Silico G-Score result of those compounds gives us preliminary hint of the potential affinity of this compound as a ligand for COX-2 receptor (PDB: 5F1A). Acute toxicity and microscopic gastrointestinal assessments indicated non-observable harmful toxicity parameters. The plantar response time of 2-((3-(chloromethyl)benzoyl)oxy)benzoic acid treated groups showed a significant increment (P < 0.01), and the nociceptive response in writhing test demonstrated a significant dose-dependent decrement. This indicated that its analgesic activity was better than acetylsalicylic acid. The platelet aggregation of 2-((3-(chloromethyl)benzoyl)oxy)benzoic acid was lower than its controls, indicating an aggregation inhibition pattern. The animals treated with 2-((3-(chloromethyl)benzoyl)oxy)benzoic acid gave a longer bleeding time. Overall, this study demonstrated a successful synthesis of pure 2-((3-(chloromethyl)benzoyl)oxy) benzoic acid. We postulated that this compound was better than acetylsalicylic acid, exhibiting excellent analgesic and antiplatelet activity with no toxicity impact.

RESUMO

OBJECTIVE: In contrast to other antibodies involved in transfusion-related acute lung injury, anti-HNA-3a antibodies are incapable of inducing direct neutrophil activation and seem to interact with endothelial cells (ECs) primarily. In animal studies, anti-HNA-3a-mediated transfusion-related acute lung injury could be precipitated in the absence of neutrophils, but was stronger when neutrophils were present. In a different context the target protein of these antibodies, choline transporter-like protein-2 (CTL-2), was reported to interact with a protein of the inner ear carrying 2 von Willebrand factor (VWF) A-domains. These observations prompted us to investigate whether VWF might be involved in anti-HNA-3a-mediated neutrophil activation, and whether signaling via CD11b/CD18 is involved, as in various other experimental settings. APPROACH AND RESULTS: Cell adhesion demonstrated specific binding of CTL-2 to VWF. Immunoprecipitation analysis of CTL-2/CD11b/CD18 coexpressing cells indicated that anti-HNA-3a colocalizes CTL-2 and CD11b/CD18 when VWF is present. Functional studies revealed that anti-HNA-3a-mediated neutrophil agglutination is an active, protein kinase C-dependent and partially Fc-dependent process. Agglutination and the production of reactive oxygen species seem to require the formation of a trimolecular complex between the target antigen (CTL-2), CD11b/CD18 and VWF. In line with these observations, anti-HNA-3a induced less severe transfusion-related acute lung injury and less neutrophil recruitment to the alveolar space in VWF knockout mice. CONCLUSIONS: We introduce CTL-2 as a new binding partner for VWF. Interaction of neutrophils with VWF via CTL-2 allows anti-HNA-3a to induce signal transduction via CD11b/CD18, which leads to neutrophil activation and agglutination. In transfusion-related acute lung injury, this mechanism may further aggravate endothelial leakage.

RESUMO

OBJECTIVE: Antibodies against human neutrophil antigen-3a (HNA-3a) located on choline transporter-like protein 2 induce severe transfusion-related acute lung injury (TRALI). This study aims to identify the mechanism implicated in anti-HNA-3a-mediated TRALI. APPROACH AND RESULTS: Our analysis shows that anti-HNA-3a recognizes 2 choline transporter-like protein 2 isoforms (P1 and P2) on human microvascular endothelial cells from lung blood vessels but reacts only with the P1 isoform on neutrophils. Direct treatment of HNA-3a-positive endothelial cells with anti-HNA-3a, but not with anti-HNA-3b, leads to reactive oxygen species production, increased albumin influx, and decreased endothelial resistance associated with the formation of actin stress filaments and loosening of junctional vascular endothelium-cadherin. In a novel in vivo mouse model, TRALI was documented by significant increase in lung water content, albumin concentration, and neutrophil numbers in the bronchoalveolar lavage on injection of human anti-HNA-3a in lipopolysaccharides-treated, as well as nontreated mice. Interestingly, although neutrophil depletion alleviated severity of lung injury, it failed to prevent TRALI in this model. Infusion of anti-HNA-3a F(ab')2 fragments caused moderate TRALI. Finally, mice lacking nicotinamide adenine dinucleotide phosphate oxidase (NOX2(y/-)) were protected from anti-HNA-3a-mediated TRALI. CONCLUSIONS: These data demonstrate the initiation of endothelial barrier dysfunction in vitro and in vivo by direct binding of anti-HNA-3a on endothelial cells. It seems, however, that the presence of neutrophils aggravates barrier dysfunction. This novel mechanism of TRALI primarily mediated by endothelial cell dysfunction via choline transporter-like protein 2 may help to define new treatment strategies to decrease TRALI-related mortality.

RESUMO

BACKGROUND: Several methods exist for the detection of neutrophil antibodies; most of them, however, require fresh neutrophils. In this study, an enzyme-linked immunosorbent assay (ELISA) using recombinant HNA-1 antigens (rHNAs) was developed to detect HNA-1a, -1b, and -1c alloantibodies in serum samples. STUDY DESIGN AND METHODS: Soluble rHNA-1a, -1b, and -1c were isolated from culture supernatant of transfected insect cells. Purified rHNA antigens were immobilized on microtiter wells using antibody against V5-Tag protein. Sera were added, and bound antibodies were detected by enzyme-labeled secondary antibodies. In parallel, monoclonal antibody-immobilized granulocyte antigen (MAIGA) was performed with two different monoclonal antibodies (MoAbs) against FcγRIIIb (3G8 and BW209). RESULTS: Fifteen MAIGA-positive sera containing HNA-1a alloantibodies were tested in ELISA. Thirteen of 15 (86.7%) MAIGA-positive sera captured by MoAbs 3G8 and/or BW209 reacted specifically with rHNA-1a. Four (26.7%) HNA-1a sera showed additional reaction with rHNA-1c. When anti-HNA-1b alloantibodies were analyzed in ELISA, 13 of 15 (86.7%) showed specific positive reaction with rHNA-1b, and 12 of 15 (80.0%) cross-reacted with rHNA-1c. Two HNA-1c sera reacted specifically with rHNA-1c. Immunoprecipitation analysis of all ELISA-negative HNA-1a and -1b sera did not show any specific band indicating false-positive reaction of these sera in MAIGA assay. CONCLUSIONS: These results suggested that rapid ELISA using recombinant neutrophil antigens may provide a valuable method for rapid screening of human alloantibodies against HNA-1a, -1b, and -1c in patients with neutropenia and in blood donors.

RESUMO

Salicylic acid (SA) derivate is well-known for its anti-inflammatory and analgesic activity through cyclooxygenase (COX)-inhibition. Previous studies pointed toward gastric toxicity induced by most salicylic acid derivative compounds, particularly acetylsalicylic acid (ASA). Despite the adverse effect, ASA is still used due to price affordability and additional advantages in preventing platelet aggregation. Recently, a novel salicylic acid derivative called 2-((3 (chloromethyl)benzoyl)oxy)benzoic acid (3-CH2Cl) was introduced as a potential alternative compound to substitute ASA. Preliminary assessment results of COX-2 specificity, toxicity profile, analgesic, anti-inflammatory, and antiplatelet activity have made 3-CH2Cl a promising compound for "new" drug development. This review focuses on the discovery, potential activity, and benefits of 3-CH2Cl and the possible molecular mechanisms of its regulations in health and disease. Thus, this review may prove to be beneficial for the utilization of 3-CH2Cl as a potential alternative drug to substitute ASA.

RESUMO

BACKGROUND: Alloantibodies against human neutrophil antigen-3 (HNA-3) are responsible for the fatalities reported in transfusion-related acute lung injury. Consequently, reliable detection of these alloantibodies is mandatory to improve blood transfusion safety. In this study, we developed stable cell lines for the detection of HNA-3 antibodies. STUDY DESIGN AND METHODS: HEK293T were transfected with HNA-3a or HNA-3b constructs and sorted by flow cytometry according to high surface expression. Transfected cells were tested with sera containing HNA-3 antibodies in flow cytometry and antibody capture assay (ACA). The results were compared with granulocyte agglutination test and granulocyte immunofluorescence test. RESULTS: In flow cytometry, 12 of 14 HNA-3a sera reacted specifically with HNA-3aa cells. One serum sample showed positive reaction with HNA-3bb cells. All HNA-3b sera recognized HNA-3bb cells. No reaction was observed with broad reactive antibodies against HLA Class I. In ACA, all HNA-3a sera (12/12) showed positive reactivity with HNA-3aa cells with no cross-reactivity with HNA-3bb cells. Again, all HNA-3b sera reacted with HNA-3bb cells only. Furthermore, genotyping of 249 individuals detected a new HNA-3 allele caused by a nucleotide substitution C>T at Position 457 leading to L(153)F mutation in choline transporter-like protein-2. This mutation impairs polymerase chain reaction with sequence-specific primers based HNA-3a typing. However, analysis with cells expressing F(153) isoform showed that this mutation did not alter the binding of HNA-3 antibodies. CONCLUSIONS: This study demonstrated that HEK293T cells expressing stable recombinant HNA-3 are suitable for the detection of HNA-3 alloantibodies allowing reliable screening of blood products.

RESUMO

BACKGROUND AND AIMS: High-performance (HP) inulin, a dietary fiber consists of more than 10 fructose polymers, have been shown to reduce post-prandial glycaemic response (PPGR) and could prevent the occurrence of Type-2 diabetes mellitus (T2DM). Currently, there are no data on whether pre-meal HP inulin supplementation could decrease PPGR. METHODS: 8 healthy adults consumed 20 g of formula that contain 60.2% inulin (w/w) dissolved in water. Blood glucose was measured in fasted participants and at 30-120 min after starting to eat a prepared meal. This test was repeated every week with different supplement formulas. CONCLUSION: pre-meal HP Inulin formula supplementation could suppress the post-prandial glycaemic response.

RESUMO

PURPOSE: This research determines the effect of sodium lauryl sulfate (SLS) as a surfactant, croscarmellose sodium (CS) as a disintegrating agent, and SLS-CS combinations on 2-((3-(chloromethyl)benzoyl)oxy)benzoic acid (3CH2Cl) (log P = 3.73) tablet formulations. In addition, this study aims to determine the optimum of the 3CH2Cl tablet formula. METHODS: The tablets are manufactured through direct compression according to the simplex lattice design. The optimal SLS and CS concentration was determined in vitro using linear and quadratic models to achieve better tablet disintegration and dissolution. RESULTS: The same linear and quadratic coefficient profiles of SLS and CS indicate that the combined coefficient of SLS-CS with a quadratic model can be used to predict the effect of the SLS-CS combination. Based on the linear model coefficients, SLS and CS increase the value of flow time (9.35; 7.65), Carr index (26.17; 21.17), hardness (9.84; 7.44), friability (0.38; 0.31), disintegrating time (5.74; 2.62), and drug release (84.28; 58.65). The quadratic model coefficient shows that SLS-CS combinations increase flow time (0.60), Carr index (2.00), hardness (1.00), and disintegrating time (1.04). Meanwhile, they decrease friability (-0.02) and drug release (-9.10). CONCLUSIONS: SLS, CS, and SLS-CS combinations affect the quality of tablet mass and tablets. The optimum tablet formula was 3CH2Cl (300 mg), Ne (9.38%), SLS (0.92%), CS (2.33%), MCC (5%), and SDL (ad 800 mg). 3CH2Cl has analgesic activity despite the presence of tablet excipients. The 3CH2Cl tablet is an innovative formulation and a new alternative for future analgesic drugs.

RESUMO

Mesenchymal stem cells (MSCs) and conditioned medium (CM) derived from human umbilical blood cord stem cells (HUBSC) are now being extensively utilized. Human umbilical vein endothelial cells (HUVECs) have the same ability as HUBSC as an option for autologous therapy. In addition, cell therapy using HUVECs may produce protective signals for cerebral vessels and promote neuronal survival after hypoxic-ischemic damage. HUVECs have the same anatomical and physiological structure as bovine umbilical vein endothelial cells (BUVECs). In this study, we aim to determine the ability of BUVEC-CM to reduce inflammation and apoptosis on in vitro neurodegeneration models (PC12 and SH-SY5Y cell lines). BUVEC-CM obtained from the third and fourth passages were analyzed using liquid chromatography-mass spectrometry (LC-MS) and high-resolution mass spectrometry (HR-MS), while the other part was used as a treatment for in vitro model neurodegeneration. The PC12 and SH-SY5Y cell lines were cultured and grouped into seven different treatments, including untreated cells. As the treatment group, cells were given TMT 10 µM in the presence of different doses of CM (25%, 50%, 75%, and 100%); as a control comparison of recent therapy, donepezil was used. In addition, cells with the administration of TMT 10 µM were run as a positive control. Cell viability assay (CCK-8) and enzyme-linked immunosorbent assay (ELISA) were performed to identify the viability and expression of interleukin-1ß (IL-1ß), caspase-3, and caspase-9 for both PC12 and SH-SY5Y cells. The results showed that BUVEC-CM could significantly reduce IL-1ß expression and downregulate caspase-3 and caspase-9, as well as when compared to the donepezil group. Taken together, these results indicate that BUVEC-CM can be used as a potential candidate for neuroprotective agents by reducing the activity of IL-1ß and the expression of caspase-9 and caspase-3 in PC12 and SH-SY5Y cells induced by TMT. However, further research still needs to be conducted.

RESUMO

BACKGROUND: Tuberculosis (TB) remains one of the highest Asia's health problems. Spondylitis TB in diabetes mellitus (DM) and hypothyroidism patients is a rare case of extrapulmonary tuberculosis. However, there is a lack of therapeutic guidelines to treat spondylitis TB, particularly with type 2 DM (T2DM) and hypothyroidism as comorbidities. Here we present a case of spondylitis TB with T2DM and hypothyroidism in a relatively young patient and its therapeutic procedure. CASE SUMMARY: We report the case of a 35-year-old male patient from Surabaya, Indonesia. Based on anamnesis, physical examination, and magnetic resonance imaging, the patient has been categorized in stage II of spondylitis TB with grade 1 paraplegia. Surprisingly, the patient also had a high HbA1c level, high thyroid stimulating hormone, and low free T4 (FT4), which indicated T2DM and hypothyroidism. A granulomatous process was observed in the histopathological section. The antituberculosis drugs isoniazid and rifampicin were given. In addition, insulin, empagliflozin, and linagliptin were given to control hyperglycemia conditions, and also levothyroxine to control hypothyroidism. CONCLUSION: The outcome was satisfactory. The patient was able to do daily activities without pain and maintained normal glycemic and thyroid levels. For such cases, we recommend the treatment of spondylitis TB by spinal surgery, together with T2DM and hypothyroidism therapies, to improve the patients' condition. Prompt early and non-invasive diagnoses and therapy are necessary.

RESUMO

Introduction: C-C chemokine receptor-2 (CCR-2) and C-C chemokine ligand-5 (CCL-5) play an important role in the migration of monocytes, macrophages, dendritic cells, and activated T cells against Mycobacterium tuberculosis (M.tb). Meanwhile, signal transducer and activator of transcription 3 (STAT-3) and suppressor of cytokine signaling 3 (SOCS-3), activated by interleukin (IL)-6 and IL-10 in tuberculosis (TB) infection, play an important role in phagocytosis, inflammation, and granulomatous-forming processes that may lead to TB treatment success or failure. However, there are no data about the expression of those markers in tuberculous lymphadenitis. The characterization of those markers is very critical to put a fundamental basis to understand the homing mechanism of tuberculous lymphadenitis. Aim of study: The specific objective of this study is to characterize the expression pattern of CCR-2-CCL-5, IL-6, IL-10, STAT-3, and SOCS-3 in tuberculous lymphadenitis. Methods: The study was performed on 27 cases of tuberculous lymphadenitis node biopsies. The diagnosis of tuberculous lymphadenitis was based on the clinical criteria and the presence of the histological feature characteristic of TB granulomas. Afterward, immunohistochemistry was stained with CCR-2, CCL-5, IL-6, IL-10, STAT-3, and SOCS-3. A semiquantitative analysis of IHC images was performed to examine protein expression in stained preparations. The expression was also manually counted. Results: Compared with the normal area, both lymphocytes and macrophages expressed strongly CCR-2-, CCL-5, and IL-6, while IL-10, STAT-3-, and SOCS-3- were expressed lowly. There was a strong positive correlation between CCR-2 with IL-6 (p = 0,83) and IL-10 (p = 0,83). Conclusion: The chronic infection process of tuberculous lymphadenitis was characterized by the expression of IL-10low, STAT-3low, SOCS-3low, CCR-2high, CCL-5high, and IL-6high. Clinical Trial Registration: Clinicaltrials.gov, identifier NCT05202548.

RESUMO

Background and aims: Meals with high protein and fiber could reduce weight and improve diabetes risk factors. Isomalto-oligosaccharide (IMO), a form of dietary fiber, could induce the afferent signal that causes appetite suppression. However, the direct effect of fiber supplementation in the form of IMO combined with a high-protein diet (HPF) on those parameters is still unknown. This study aims to investigate the effect of HPF on anthropometric parameters and blood glucose regulation of healthy subjects. . Methods: Thirteen healthy subjects were given a hypocaloric high protein diet (HPD) mixed with their prepared meals for two weeks. Followed by the HPF diet for another two weeks. Their anthropometric parameters, such as body composition (total body weight, body fat percentage, and fat-free mass), BMI and waist circumference, and fasting plasma glucose, were measured. Results: Compared to pre-intervention, HPF could significantly (p ≤ 0.004) reduce the anthropometric parameters and fasting plasma glucose. Compared to HPD, HPF could significantly (p ≤ 0.005) reduce more total body weight, body fat percentage, and BMI. In addition, HPF could induce more satiety than HPD (higher VAS score). Conclusion: HPF could improve the subject's anthropometric parameters which is obviously beneficial in preventing the risk of developing diabetes.

RESUMO

Ocimum sanctum (OS) is tropical herbal plant which is easy to find and widely used as a vegetable food in Indonesia. In last decade, lung adenocarcinoma was in top position as male cancer disease in Indonesia. Recently, emerging data showing the extracts of different species of Ocimum exhibiting the anti-tumor properties. Further studies on lung lewis carcinoma demonstrated pro-apoptosis effects after the treatment with Ocimum extracts. However, the effect of OS of Indonesian origin in human alveolar pulmonary adenocarcinoma A549 cells remain unclear. Therefore, we aimed to investigate effects of ethanolic extract OS (EEOS) in A549 cell culture systems. Cell adhesion and viability assays revealed that EEOS significantly decreased the attachment into extracellular matrix of A549 cells. Morphological examination AO/EB and DAPI staining indicated that EEOS induced the cells shrinkage, DNA fragmentation and condensation of A549 cells. Further, EEOS treatment induced the apoptosis rate followed by up-regulation of reactive oxygen species (ROS), caspase-3 expression and decreased anti-apoptotic protein Bcl-2. This condition also suppressed the expression of SOD2 as well as the GPx. In conclusion, our findings indicate that EEOS suppressed the viability of A549 cells, which may result from the activation of ROS promoting the apoptosis signaling via mitochondrial intrinsic pathway. Taken together, EEOS might be a good therapeutic potential to further understand its properties in the treatment of lung carcinoma.
