RESUMEN

Background As a result of the chronic nature of type 2 diabetes mellitus (T2DM), its complications, and treatment complexity, patients should have a comprehensive knowledge of various aspects of T2DM management and follow-up. The study aimed to assess T2DM patients' knowledge of disease complications and their screening strategies and the management targets for glucose, lipids, blood pressure, and body weight. Methods This was a cross-sectional and questionnaire-based study including 205 adult patients with T2DM from November 2023 to March 2024. The patients were randomly selected at one tertiary endocrine center and the outpatient clinics of three teaching hospitals in Basrah, southern Iraq. Social and disease-related data were collected. Another 18 T2DM-related questions were designed to assess the patients' knowledge about the aim of treatment; T2DM complications and their screening; the recommended targets for glycemic, lipid, and blood pressure control; and the recommended exercise and weight loss. We gave one point for each correct answer and considered a final score of 10/18 as adequate.  Results Of a total of 205 patients, 109 (53.2) were women. The mean age for patients was 48.7 ± 13.1 years. Based on the patients' responses, 107 (52.2%) had adequate knowledge about T2DM. Questions about the target fasting and post-prandial capillary blood glucose, HbA1c target and frequency, and naming the current treatment were the most correctly answered questions (80.9%, 73.1%, 68.7%, and 72.6%, respectively). Questions about the lipid target, definition of hypoglycemia, and ideal lifestyle for T2DM (exercise and bodyweight loss) were least correctly answered. Patients younger than 40 years old, being a man, with a higher educational level, and T2DM duration of more than five years had significantly higher T2DM knowledge. Conclusions Only half of the patients had adequate T2DM knowledge. Better degree of knowledge was particularly observed in patients with younger age, male gender, higher educational level, and longer T2DM duration. There is a need to promote diabetes education strategies for people with T2DM.

RESUMEN

This study presents a family with nine children, two of them diagnosed with RTS2 using genetic testing. The other siblings show some of the RTS2 criteria and are suggestive of the syndrome. Such reports help physicians be more alert in dealing with cases of rare syndromes. Timely initiation of genetic counseling and testing once the first child was diagnosed with the syndrome could have prevented the birth of affected siblings by RTS2. Since RTS2 patients could have a severe clinical manifestation as osteosarcoma which probably leads to death at a young age, the importance of genetic testing is even more underlined.

RESUMEN

BACKGROUND: Nanotechnology-based drug delivery systems have received much attention over the past decade. In the present study, we synthesized Methyl Urolithin A-loaded solid lipid nanoparticles decorated with the folic acid-linked chitosan layer called MuSCF-NPs and investigated their effects on cancer cells. METHODS: MuSCF-NPs were prepared using a high-pressure homogenization method and characterized using FTIR, FESEM, DLS, and zeta potential methods. Drug encapsulation was assessed by spectrophotometry and its cytotoxic effect on various cancer cells (MDA-MB231, MCF-7, PANC, AGS, and HepG2) by the MTT method. Antioxidant activity was assessed by the ABTS and DPPH methods, followed by expression of genes involved in oxidative stress and apoptosis by qPCR and flow cytometry. RESULTS: The results showed the formation of monodisperse and stable round nanoparticles with a size of 84.8 nm. The drug loading efficiency in MuSCF-NPs was reported to be 88.6%. MuSCF-NPs exhibited selective cytotoxicity against MDA-MB231 cells (IC50 = 40 µg/mL). Molecular analysis showed a significant increase in the expression of Caspases 3, 8, and 9, indicating that apoptosis was occurring in the treated cells. Moreover, flow cytometry results showed that the treated cells were arrested in his SubG1 phase, confirming the pro-apoptotic effect of the nanoparticles. The results indicate a high antioxidant effect of the nanoparticles with IC50 values ​​of 45 µg/mL and 1500 µg/mL against ABTS and DPPH, respectively. The reduction of catalase gene expression confirmed the pro-oxidant effect of nanoparticles in cancer cells treated at concentrations of 20 and 40 µg/mL. CONCLUSIONS: Therefore, our findings suggest that the MuSCF-NPs are suitable candidates, especially for breast cancer preclinical studies.

RESUMEN

This study concerns the removal of a trihydrate antibiotic (Amoxicillin) from synthetically contaminated water by adsorption on modified bentonite. The bentonite was modified using hexadecyl trimethyl ammonium bromide (HTAB), which turned it from a hydrophilic to a hydrophobic material. The effects of different parameters were studied in batch experiments. These parameters were contact time, solution pH, agitation speed, initial concentration (C0) of the contaminant, and adsorbent dosage. Maximum removal of amoxicillin (93 %) was achieved at contact time = 240 min, pH = 10, agitation speed = 200 rpm, initial concentration = 30 ppm, and adsorbent dosage = 3 g bentonite per 1L of pollutant solution. The characterization of the adsorbent, modified bentonite, was accomplished using Fourier transform infrared spectroscopy, scanning electron microscopy, X-ray diffraction, and Brunauer-Emmett-Teller. The isotherm models were also investigated, and it was found that the Freundlich isotherm model fitted well with the experimental data (R2 = 94.77), which suggests heterogeneity in the multilayer adsorption of amoxicillin onto modified bentonite. The kinetics of the adsorption process were studied. The experimental data were found to obey the pseudo-first-order kinetic model (R2 = 95.1). Thermodynamic studies indicated that the adsorption process was physisorption and endothermic. Finally, the modified bentonite proved to be a good adsorbent for the removal of amoxicillin from contaminated solutions.

RESUMEN

One approach to accelerate the availability of new cancer drugs is to test drugs approved for other conditions as anticancer agents. During recent decades, penciclovir (PNV) has been frequently utilized as a potent antiviral drug, in particular against infections caused by herpes viruses. Many antivirals interact with DNA and change their expression level, so determining the binding mode is of great importance. In our laboratory, we have focused our attention to design improved drugs that target cellular DNA, to understand the mechanism of action at the molecular level, and also to investigate the effect of antiviral drugs as anticancer agents. The results of ct-DNA-PNV interactions at physiological pH using fluorescence spectroscopy, UV-visible absorption spectroscopy, and molecular modeling reveal this drug binds well to ct-DNA through groove binding. The circular dichroism measurements displayed that PNV caused a slight change in the DNA structure which affirmed that the binding of PNV with the DNA occurs through the groove mode. Besides, multi-spectroscopic and molecular docking were used to evaluate how PNV interacts with human serum albumin under physiological conditions. The findings of fluorescence quenching suggested that static quenching was involved in the spontaneous development of HSA-PNV complex through hydrophobic force. The docking simulation results validated the findings of spectroscopic techniques.Communicated by Ramaswamy H. Sarma.

RESUMEN

BACKGROUND: Recent advances in the treatment of breast cancer have resulted in improved overall cancer survival; however, cancer therapy related cardiac dysfunction is considered a major adverse effect of several chemotherapeutic agents, particularly anthracyclines. Hence, there is a need to develop proper cardioprotective strategies to limit myocardial injury following chemotherapy. OBJECTIVE: To evaluate the effect of statin therapy on prevention of anthracycline- induced cardiotoxicity in female patients with breast cancer. PATIENTS AND METHODS: The current study is a prospective, randomized, single-blind, placebo-controlled trial in which we enrolled a total of 110 female patients with newly diagnosed breast cancer who received anthracycline based chemotherapy. Patients were randomly assigned in 1:1 ratio into two groups, study group in which patients received 40 mg of oral atorvastatin and control group in which patients received placebo. A comprehensive echocardiographic examination was performed to all patients prior to receiving the chemotherapy and after 6 months, assessment of LV ejection fraction was done by 3D-echocardiography. All echocardiographers were blinded to all the patients' characteristics and assignment to either group. RESULTS: The mean age of patients assigned to the control group was 49.8±10.51 years old, while patients assigned to the intervention group had mean age of 47.84± 9.16 years old, both the control group and the intervention group were similar in demographic data and baseline clinical characteristics. There was a highly significant difference between the two groups regarding both the absolute LVEF assessed by 3D- echocardiography at 6 months and the percentage of change compared to baseline values, patients assigned to the control group had mean LVEF of 52.92% at 6 months with percentage of change reaching -7.06%, while those assigned to the intervention group had mean LVEF reaching 56.22% at 6 months with a percentage of change reaching -3.64% (P-value: 0.008 and 0.004 for the absolute value and percentage of change respectively). There was a significant difference between the two groups regarding incidence of development of cancer therapy related cardiac dysfunction (CTRCD); defined as drop in LVEF more than 10% and to a value below 53% assessed by 3D echocardiography, among the control group 15 patients (30%) developed CTRCD after 6 months from starting Anthracyclines based chemotherapy, while, among the intervention group only 6 patients (12%) developed CTRCD. (P-value= 0.027) CONCLUSION: Prophylactic use of atorvastatin may prevent the development of cancer therapy related cardiac dysfunction in breast cancer patients receiving anthracycline based chemotherapy.

RESUMEN

Autoimmune rheumatoid arthritis (RA) is a systemic condition closely correlated with a variety of autoantibodies (Abs) that could be considered diagnostic and prognostic markers. The current research was designed to detect the diagnostic values for a number (n) of these auto-Abs in RA detection and to evaluate the accuracy of a combined diagnostic scheme. This prospective study was conducted between September 2021 and August 2022 and included 110 subjects with RA, 70 individuals with other autoimmune disorders as positive controls (PC), and 50 unrelated, apparently healthy individuals as healthy controls (HC). The eligibility criteria for all study groups were followed stringently. An enzyme-linked immunosorbent assay (ELISA) was employed to measure rheumatoid factors (RF), cyclic citrullinated peptide antibodies (CCP-Abs), mutated citrullinated vimentin antibodies (MCV-Abs), anti-perinuclear factor antibodies (APF-Abs), and anti-keratin antibodies (AKA). We calculated the specificity, sensitivity, and predictive values of all auto-Abs. Significantly higher levels of anti-CCP-Abs, anti-MCV-Abs, APF-Abs, and AKAs were reported in the RA patients compared to the HC and PC subjects. RF levels, however, were only statistically elevated when compared to the HC individuals. Anti-APF-Abs had a higher sensitivity rate (70.9%), and anti-CCP-Abs had a higher specificity rate (94.16%) compared to other auto-Abs, whereas the combined detection scheme revealed a higher sensitivity (81.81%) and excellent specificity (90.83%) compared to the two former auto-Abs. Anti-perinuclear factor-Ab was a highly sensitive test, and CCP-Ab was a surpassingly specific assay for identifying RA. Furthermore, the combined detection scheme is an essential serological approach for RA diagnosis and crucial in differentiating this disease from other autoimmune diseases, thus promoting early diagnosis and treatment.

RESUMEN

The standard procedure for the diagnosis of prostate carcinoma involves the collection of 10-12 systematic biopsies (SBx) from both lobes. MRI-guided targeted biopsies (TBx) from suspicious foci increase the detection rates of clinically significant (cs) PCa. We investigated the extent to which the results of the TBx predicted the tumor board treatment decisions. SBx and TBx were acquired from 150 patients. Risk stratifications and recommendations for interventional therapy (prostatectomy and radiotherapy) or active surveillance were established by interdisciplinary tumor boards. We analyzed how often TBx alone were enough to correctly classify the tumors as well as to indicate interventional therapy and how often the findings of SBx were crucial for therapy decisions. A total of 28/39 (72%) favorable risk tumors were detected in TBx, of which 11/26 (42%) very-low-risk tumors were not detected and 8/13 (62%) low-risk tumors were undergraded. A total of 36/44 (82%) intermediate-risk PCa were present in TBx, of which 4 (9%) were underdiagnosed as a favorable risk tumor. A total of 12/13 (92%) high-risk carcinomas were detected and correctly grouped in TBx. The majority of csPCa were identified by the sampling of TBx alone. The tumor size was underestimated in a proportion of ISUP grade 1 tumors. Systematic biopsy sampling is therefore indicated for the next AS follow-up in these cases.

RESUMEN

Parkinson's disease (PD) is a neurodegenerative disease characterized by deposition of α-synuclein and aggregation of Lewy bodies. Cholesterol is involved with PD neuropathology in bidirectional ways that could be protective or harmful. Thus, the objective of the present review was to verify the potential role of cholesterol in PD neuropathology. Deregulation of ion channels and receptors induced by cholesterol alteration suggests a possible mechanism for the neuroprotective effects of cholesterol against PD development. However, high serum cholesterol level increases PD risk indirectly by 27-hydroxycholesterol which induces oxidative stress, inflammation, and apoptosis. Besides, hypercholesterolemia triggers the accumulation of cholesterol in macrophages and immune cells leading to the release of pro-inflammatory cytokines with progression of neuroinflammation subsequently. Additionally, cholesterol increases aggregation of α-synuclein and induces degeneration of dopaminergic neurons (DN) in the substantia nigra (SN). Hypercholesterolemia may lead to cellular Ca2+ overload causing synaptic and the development of neurodegeneration. In conclusion, cholesterol has bidirectional effects on PD neuropathology and might be protective or harmful.

RESUMEN

In this study, a newly-designed copper(ii) complex of metformin and l-proline which was immobilized on Fe3O4 MNPs was developed. The structure of the catalyst platform was fully characterized using spectroscopic analyses. Moreover, the catalytic activity of [Fe3O4@Cu(ii)(Met)(Pro-H)2] was investigated in a one-pot synthesis of a variety of functionalized ethers in reasonable to excellent yields through Ullman reaction in an aqueous environment using various aryl halides, phenol, and Cs2CO3 and without using any external Cu-reducing agents. Notably, gentle catalytic conditions, quick reaction times, applicability, low cost, and preventing dangerous chemicals and solvents during synthesis and catalytic application are some of the superior properties of the [Fe3O4@Cu(ii)(Met)(Pro-H)2] complex. Furthermore, the catalyst can be reused for several runs (at least eight times) without remarkable loss in efficiency.

RESUMEN

INTRODUCTION: Post-stroke spasticity (PSS) is a disorder of the sensory-motor control, leading to upper motor neuron lesions manifesting either as intermittent or sustained involuntary activation of muscles. Botulinum neurotoxin-A (BoNT-A) is mostly utilized in a variety of therapeutic indications, and it is effective and safe in the management of focal PSS in the rehabilitation scenario. The study aimed to evaluate the effect of BoNT-A administration on H-reflex of upper and lower limbs following PSS. In addition, the investigation of the association among the degree of spasticity (assessed by the Modified Ashworth Scale [MAS]) and motor neuron pool excitability (assessed by analysing H-reflex excitability) was done. MATERIAL AND METHODS: Fifty patients with a stroke of either sex aged 30 to 60 years presented with either upper or lower limb focal spasticity were studied. BoNT-A was given on two occasions to the gastrocnemius, soleus, biceps brachii muscles and flexor carpi radialis (FCR). H-reflex was documented from the FCR and soleus muscles at baseline and 3-4 weeks post BoNT-A injection. Medical Research Council scale and MAS were used to assess the PSS and muscle strength. RESULTS: H-reflex latency and amplitude, H/M ratio recorded from FCR and soleus muscles were significantly different between pre- and post-management. The MRC scale was significantly increased whereas the MAS was significantly reduced post BoNT-A injection. CONCLUSIONS: BoNT-A causes obvious improvement in PSS clinically as assessed by MAS and MRC scale as well as neurophysiologically by H-reflex. A negative correlation between H-reflex latency but not the amplitude or H max /M max ratio and MAS was observed.

RESUMEN

Artificial intelligence has emerged as a powerful tool for solving real-world problems in various fields. This study investigates the simulation and prediction of nitrate adsorption from an aqueous solution using modified hydrochar prepared from sugarcane bagasse using an artificial neural network (ANN), support vector machine (SVR), and gene expression programming (GEP). Different parameters, such as the solution pH, adsorbent dosage, contact time, and initial nitrate concentration, were introduced to the models as input variables, and adsorption capacity was the predicted variable. The comparison of artificial intelligence models demonstrated that an ANN with a lower root mean square error (0.001) and higher R2 (0.99) value can predict nitrate adsorption onto modified hydrochar of sugarcane bagasse better than other models. In addition, the contact time and initial nitrate concentration revealed a higher correlation between input variables with the adsorption capacity.

RESUMEN

BACKGROUND: Biobanking of prostate carcinoma is particularly challenging due to the actual cancer within the organ often without clear margins. Frozen sections are to date the only way to examine the biobank material for its tumor content. We used ex vivo fluorescence confocal microscopy (FCM) to analyze biobank samples prior to cryoasservation. METHODS: 127 punch biopsies were acquired from prostatectomy-specimens from 40 patients. These biopsies were analyzed with a Vivascope 2500-G4 prior to their transfer to the biobank. In difficult cases, larger samples of the prostatectomy specimens were FCM scanned in order to locate tumor foci. After patient acquisition, all samples were taken from the biobank and analyzed. We compared the results of the FCM examinations with the results of conventional histology and measured the DNA content. RESULTS: With upstream FCM, the tumor content of biobank samples could be determined with high confidence. The detection rate of representative biobank samples was increased due to the rapid feedback. The biobank samples were suitable for further molecular analysis. CONCLUSION: FCM allows for the first time lossless microscopic analysis of biobank samples prior to their cryoasservation and guarantees representative tumor and normal tissue for further molecular analysis.

RESUMEN

Trichomonas tenax (T. tenax) and Entamoeba gingivalis (E. gingivalis) are two oral protozoan parasites that are universal and found in patients with poor oral hygiene, as well as chronic and periodontal diseases. This study was conducted to assess the efficacy of some parameters, such as age, gender, education, residency, smoking, and dental cleaning routines, on the incidence of these parasites in the oral cavity of the patients participating in this study. A total of 230 individuals with chronic diseases, 97 of whom were patients (44 females and 53 males) participated in the present study. Dental plaque and saliva samples were collected from each patient and examined under light microscopy with Giemsa staining. Out of 230 dental plaque samples, 60 (26.08%) samples were positive for E. gingivalis, while 37 (16.08%) cases were positive for T. tenax. Diabetic patients showed high E. gingivalis percentage (n=12; 20%) (P=0.000*). However, thyroid disorders showed a low percentage. Hypertensive patients showed a high percentage for T. tenax (n=6; 16.21%) (P=0.000*), while tuberculosis patients showed the lowest percentage. Patients with hypertension, smoking, heart disease, and diabetes showed statistical significance for the presence of these parasites. Equally, patients older than 30 years have shown a higher rate of infection. According to the findings, E. gingivalis was detected in 58.33% and 41.66% of the urban and rural populations, respectively. Furthermore, T. tenax was detected in 81.08% and 18.91% of the urban and rural populations, respectively. Parasitic contagions were comparatively popular in patients with chronic and periodontal illness.

RESUMEN

Endometrial hyperplasia is defined as a common clinical disorder caused by the increased levels of estrogens with low levels of progesterone; therefore, this hormonal imbalance leads to an increase in the proliferation rate of the endometrial cells. Endometrial carcinoma is one of the most important malignancies affecting women all over the world "accounting for 37.7% of all other disorders affecting the female reproductive system". The expression of the Ki-67 protein is related to the proliferative behavior of malignant tumor cell populations of their own, allowing it to be used as a marker of tumor aggressiveness. The present study was conducted to examine the expression of the proliferation marker, Ki-67 in various endometrial lesions. Ki-67 expression was evaluated in 60 endometrial samples that resulted as either endometrial curetting or hysterectomy specimens, diagnosed with simple hyperplasia (n=10), complex hyperplasia (n=20), atypical hyperplasia (n=6), and endometrial carcinoma (n=24). In patients with endometrial carcinoma, there was an increased expression of Ki-67, compared to proliferative endometrium and simple hyperplasia (P-value=0.0001). There was no such discrepancy between atypical hyperplasia and endometrial carcinoma cases. The expression of Ki-67 showed a positive association with the degree of endometrial cancer (P-value=0.0013), however, not with the age of the patients (P-value>0.05). There is a wide range of variations in the proliferation rate within the development of different endometrial lesions, including benign and malignant lesions. Our findings may be of value in differential diagnosis and prognosis of endometrial hyperplasia and endometrial carcinoma.

RESUMEN

Background: Uncertainty intolerance (IU), the tendency to think or react negatively toward uncertain events may have implication on individuals' mental health and psychological wellbeing. The Intolerance of Uncertainty Scale-12 (IU-12) is commonly used across the globe to measure IU, however, its' psychometric properties are yet to be evaluated in Iran with a Persian-speaking population. Therefore, the purpose of this research was to translate and validate the IU-12 among Iranian undergraduate students. Materials and Methods: The multi-stage cluster random sampling was employed to recruit 410 Iranian undergraduate students (260 females) from the Azad University to complete the IU-12, the Depression Anxiety Stress Scale-2, and the Penn State Worry Questionnaire in a cross-sectional design. In this study, face validity, content validity, construct validity, and concurrent validity were measured and Construct Reliability (CR) and Cronbach's alpha were used to measure reliability. Results: The impact score of the translated IU-12 indicated acceptable face validity (value of impact score was greater than 1.5). The value of Content Validity Index (CVI) and the value of Content Validity Ratio (CVR) were above 0.7 and 0.78, respectively. The values of CVI and CVR indicated the items had acceptable content validity and were deemed essential to the measure. The measurement model analysis showed the measure with two subscales had good fit indices (CMIN/df = 2.75, p < 0.01, RMSEA = 0.07, TLI = 0.94, CFI = 0.95, GFI = 0.94). A Confirmatory Factor Analysis (CFA) indicated the scale was composed of the two subscales found in the English-version of the scale (prospective anxiety and inhibitory anxiety), and no items were removed from the scale. The values of CR (0.86) and Cronbach's alphas (0.89) showed the measure had appropriate internal consistency. Conclusion: The findings support the psychometric properties of the Persian version of the IU-12. This scale could be used to reliably and accurately measure uncertainty intolerance among undergraduate students in Iran.

RESUMEN

Interpersonal mindfulness is a construct that significantly contributes to social interaction. To date, no validated measure assessing interpersonal mindfulness has been developed in Iran. Therefore, the aim of this study was to translate and validate the Interpersonal Mindfulness Scale (IMS) among Iranian undergraduate students. Participants in the study (370 undergraduate students; 220 females) from the Azad University completed the translated IMS, the Five Facet Mindfulness Questionnaire, and the Inventory of Interpersonal Problems Scale. The translated measure demonstrated acceptable face validity. All items had acceptable content validity and were deemed essential to the scale. The results of a Confirmatory Factor Analysis (CFA) confirmed a scale with four subscales (presence, awareness of self and others, non-judgmental acceptance, and non-reactivity), with acceptable internal consistency. The findings support the psychometric properties of the Persian translated Interpersonal Mindfulness Scale, which could be used to measure interpersonal mindfulness among undergraduate students in Iran.

RESUMEN

Toxoplasma gondii is intracellular parasite; it is considered one of the most important causes of miscarriage and can inhibit the development of the fetus, especially at the beginning of pregnancy. Host lipids have an important role in the pathogenesis of T. gondii infection. Proprotein convertase subtilisin/kexin type 9 (PCSK9) is a liver secreted protein that has the unusual ability to interfere and block the natural recycling of lipid receptors, resulting in impaired lipid clearance from the plasma. This study designed to investigate the role of PCSK9 in recycling blood lipid levels in women with acute toxoplasmosis and to evaluate the relationship between them. Forty serum blood samples were collected from aborted women, who were having acute toxoplasmosis (IgM and IgA positive result) for the period October 2020 to March 2021. In addition, 25 samples were collected from apparently-healthy women (negative control group) and 25 samples collected from other aborted women (positive control group). Both groups gave negative result for the presence of IgM, IgA and IgG-Toxoplasma antibodies. Finally, PCSK9 and blood lipids levels were measured for all groups. Positive relations were found between lipid profile values and T. gondii infected women. There were an increased in triglycerides (149.65 mg/dl), HDL (38.5 mg/dl), VLDL (140.53 mg/dl) values, while there was a decreased in LDL values (41.7 mg/dl). The PCSK9 was a highly significant increase in PCSK9 in T. gondii infected women (3.23) compared with aborted and healthy control groups (1.57, 1.15 respectively). The measurement of PCSK9 can be used as a biomarker and may be useful in screening for acute toxoplasmosis. In spite of a highly significant increase in PCSK9 and blood lipids in acute toxoplasmosis, there was a decrease in BMI. This may be due to toxoplasmosis infection.

RESUMEN

Although there are several methods for assessing the sun protection factor (SPF) of sunscreen products, there is no standard and reliable in vitro method. Each test entails limitations and drawbacks. Therefore, this study aimed to assess the employability of FTIR as an alternative and quick method to evaluate the efficacy of various sunscreen formulations, their concentrations, and the timing of their application. Infrared radiation has longer wavelengths than ultraviolet, penetrates deeply into the skin, and hence enables the understanding of sunscreens' ability to block the transmission of radiation. The FTIR transmission using synthetic skin to study the effect of sunscreen agents (oxybenzone, octyl methoxycinnamate, titanium dioxide (TiO2), and zinc oxide (ZnO)) was conducted in the range 450-4000cm-1. Comparison studies were made at the peak of 805cm-1. After 2 h of sunscreen application, using the maximum concentrations, the FTIR peak at wavenumber 805cm-1 demonstrated a significant reduction of transmission from 96.55 to 60.09%, 57.59%, 32.02%, and 37.1% for oxybenzone, octyl methoxycinnamate, TiO2, and ZnO respectively (P<0.05). A significant reduction in transmission was observed (P<0.05) with increasing sunscreen concentrations after 2 h of application. Nevertheless, the upper limit of concentration showed no appreciable change from the middle level of concentration, and hence it is cost-effective to employ the middle concentration. Inorganic sunscreens showed a higher protection level than organic. Fixed-dose combinations of sunscreens showed an enhanced effect yet were not synergistic. In conclusion, the use of FTIR spectroscopy with synthetic skin is a quick and user-friendly technique that enables the assessment of the efficacy of sunscreen formulations.
