Progress towards a standardized model of ocular sulfur mustard injury for therapeutic testing

Sulfur mustard (SM) remains a highly dangerous chemical weapon capable of producing mass casualties through liquid or vapor exposure. The cornea is highly sensitive to SM toxicity and exposure to low vapor doses can cause incapacitating acute injuries. At higher doses, corneas fail to fully heal and subsequently develop a constellation of symptoms known as mustard gas keratopathy (MGK) that causes reduced quality of life and impaired or lost vision. Despite a century of research, there are no specific treatments for acute or persistent ocular SM injuries. Here I summarize toxicological, clinical and pathophysiological mechanisms of SM vapor injury in the cornea, describe a preclinical model of ocular SM vapor exposure for reproducible therapeutic studies, and propose new approaches to improve evaluation of therapeutic effects. I also describe recent findings illustrating the delayed development of a transient but severe recurrent corneal lesion that, in turn, triggers the emergence of secondary keratopathies characteristic of the chronic form of MGK. Development of this recurrent lesion is SM dose-dependent, although the severity of the recurrent lesion appears SM dose-independent. Similar recurrent lesions have been reported in multiple species, including humans. Given the mechanistic relationship between the recurrent lesion and chronic, secondary keratopathies, I hypothesize that preventing the development of the recurrent lesion represents a novel and potentially valuable therapeutic approach for treatment of severe corneal SM injuries. Although ocular exposure to SM vapor continues to be a challenging therapeutic target, establishing consistent and reproducible models of corneal injury that enhance mechanistic and pathophysiological understanding will help satisfy regulatory requirements and accelerate the development of effective therapies.

Evaluation of therapeutic effects of camel milk against the hepatotoxicity and nephrotoxicity induced by fipronil and lead acetate and their mixture

Elevated environmental pollution of lead and fipronil is blamed for chronic toxicity. Fipronil and lead acetate are commonly used, but now no adequate data is available concerning the harmful side effects of their mixture. The present work investigated the curative effects of camel milk against lead and fipronil subchronic toxicity individually and as mixture with different doses (1/30 and 1/60 LD50) on male albino rats by oral ingestion. Rats were divided into eight groups; the first group (G1) was the normal health control. G2, G4, G6, and G8 are the normal health groups camel milk. G3 and G4 are ingested by 1/30 LD50 of the fipronil formulation. G5 and G6 are ingested by 1/30 LD50 of lead acetate. G7 and G8 are ingested by 1/60 LD50 of lead acetate and 1/60 LD50 of fipronil formulation. The lead acetate or fipronil and their mixture significantly induced destructive damage to the kidneys and liver function parameters as well as lipid profile and oxidative stress in both organs. Serum LDH activity increased under the same conditions. Most harmful effects were clearly observed in G7 followed by G3 and G5. Histological examination revealed hepatic degeneration and nephropathy in intoxicated rats relative to normal health control, as shown by hypertrophy of hepatocytes in addition to karyomegaly, binucleation, and mild individual cell coagulative and mild hypertrophy, as well as a vacuolar degeneration of tubular epithelium in the kidneys. Both toxicants in their mixture showed more harmful than those of their individual ones. Camel milk treatments into intoxicated animals (lead, fipronil, and mixture groups) attenuated all evaluated parameters, alleviated the harmful influences of the mixture of lead acetate and fipronil, and improved the biomarkers of their oxidative stress.

Evaluating the treatment outcomes of repetitive transcranial magnetic stimulation in patients with moderate-to-severe Alzheimer's disease.

The repetitive transcranial magnetic stimulation (rTMS) shows great potential in the treatment of Alzheimer's disease (AD). However, its treatment efficacy for AD patients in moderate to severe stage is relatively evaluated. Here, we proposed a randomized, sham-controlled, clinical trial of rTMS among 35 moderate-to-severe AD patients. A high frequency (10 Hz) stimulation of the left dorsal lateral prefrontal cortex (DLPFC), 60-session long treatment lasting for 3 months procedure was adopted in the trial. Each participant completed a battery of neuropsychological tests at baseline and post-treatment for evaluation of the rTMS therapeutic effect. Twelve of them completed baseline resting-state functional magnetic resonance imaging (fMRI) for exploration of the underlying neural contribution to individual difference in treatment outcomes. The result showed that the rTMS treatment significantly improved cognitive performance on the severe impairment battery (SIB), reduced psychiatric symptoms on the neuropsychiatric inventory (NPI), and improved the clinician's global impression of change (CIBIC-Plus). Furthermore, the result preliminarily proposed resting-state multivariate functional connectivity in the (para) hippocampal region as well as two clusters in the frontal and occipital cortices as a pre-treatment neuroimaging marker for predicting individual differences in treatment outcomes. The finding could brought some enlightenment and reference for the rTMS treatment of moderate and severe AD patients.

Evaluation and comparison of therapeutic effects of probiotics and colloidal bismuth subcitrate on abdominal bloating.

Functional abdominal bloating is one of the functional gastrointestinal disorders (FGIDs). Here, we aimed to investigate and compare the effects of probiotics and colloidal bismuth subcitrate on abdominal bloating. This was a double-blinded randomized clinical trial performed on 125 patients with functional abdominal bloating in Isfahan in 2020-2021. At the beginning of the study, information on the frequency of abdominal bloating, its severity, the occurrence of early satiety, frequency of borborygmus, frequency of belching, and the frequency of defecation per week was collected. Patients were divided into 3 groups receiving familact probiotic pills that contained 7 bacterial strains, colloidal bismuth subcitrate tablets, and placebo pills for 4 weeks. Afterwards, the frequency and severity of abdominal bloating and other symptoms were compared. After 2 weeks, patients in the probiotic group had a significantly lower frequency of abdominal bloating compared to other groups (P= 0.006). After 4 and 8 weeks, patients in the probiotic group and bismuth group had a lower frequency of bloating )3.18±3.02, 4.11±3.34) compared to placebo (5.10±3.54) (P= 0.001 and P= 0.037, respectively). During the study, patients in the probiotic group had a significantly lower bloating severity (41.90% had no symptom) compared to bismuth and placebo groups (12.50 ,12.00% had no symptom) (p< 0.05). The frequency of borborygmus was significantly lower in the probiotic group after 2 and 4 weeks during the study compared to other groups (1.62±0.2 Vs 2.69±0.3, 2.45±0.3 ) (P= 0.010 and P= 0.013, respectively). According to our data, consumption of probiotics improves the frequency and severity of abdominal bloating and reduces borborygmus. Colloidal bismuth subcitrate also has significant effects.

Evaluation of Therapeutic Effect of Buspirone in Improving Dysphagia in Patients with GERD and Ineffective Esophageal Motility: A Randomized Clinical Trial

Background: Ineffective esophageal motility (IEM) is the most common esophageal motility disorder associated with low-to-moderate amplitude contractions in the distal esophagus in manometric evaluations. Despite recent new conceptions regarding the pathophysiology of esophageal motility and IEM, there are still no effective therapeutic interventions for the treatment of this disorder. This study aimed to investigate the effect of buspirone in the treatment of concomitant IEM and GERD. Methods and Materials: The present study was a randomized clinical trial conducted at the Imam Khomeini Hospital, Tehran. Patients with a history of gastroesophageal reflux disease and dysphagia underwent upper endoscopy to rule out any mechanical obstruction and were diagnosed with an ineffective esophageal motility disorder based on high-resolution manometry. They were given a package containing the desired medication(s); half of the packets contained 10 mg (for 30 days) of buspirone and 40 mg (for 30 days) of pantoprazole, and the other half contained only 40 mg (for 30 days) of pantoprazole. Dysphagia was scored based on the Mayo score, as well as a table of dysphagia severity. Manometric variables were recorded before and after the treatment. Results: Thirty patients (15 pantoprazole and 15 pantoprazole plus buspirone) were included. Females comprised 63.3% of the population, with a mean age of 46.33 ± 11.15. The MAYO score and resting LES pressure significantly changed after treatment. The MAYO and Swallowing Disorder Questionnaire scores significantly decreased after treatment in both groups of patients. Our results revealed that the post-intervention values of manometric variables differed significantly between the two groups after controlling for the baseline values of the variables. This analysis did not demonstrate the superiority of buspirone. Conclusion: Buspirone seems to have no superiority over PPI. Treatment with concomitant IEM and GERD using proton pump inhibitors improves the patient’s clinical condition and quality of life. However, adding buspirone to the treatment regimen did not appear to make a significant difference in patient treatment.

Comparison Of Handicap Inventory Tinnitus Scores Before and After Intra Tympanic Steroid Injection In Tinnitus Patients

Introduction. Tinnitus is a symptom in the form of a conscious perception of sound that is not produced by a sound source outside the body. Patients with tinnitus often have complaints of quality of life, with some situations of extreme anxiety, depression, and life changes. The Tinnitus Handicap Inventory (THI) is a valid questionnaire to be associated with patients associated with tinnitus. The Tinnitus Research Initiative (TRI), an international academic organization founded in 2006, recommends the use of THI for the evaluation of tinnitus defects and therapeutic effects. Therefore, a THI assessment is needed at RSUP Dr. Mohammad Hoesin Palembang as a result of therapy. Methods. This research using a design that aims to determine the comparison of THI scores before and after intratympanic injection of corticosteroids in 18 samples at RSUP Dr. Mohammad Hoesin Palembang. Results. The average age of the sample was 57 (23-66) years and the number of men and women were the same, namely 9 (50%) samples. Most of the samples had problems in unilateral ears by 14 (77,8%) samples. The average THI before intratympanic steroid injection was 37 (12-72) and after injection was 20 (4-80). Wilcoxon test results showed significant changes between before and after intratympanic steroid injection. Conclusion. There was a significant improvement in THI scores after intratympanic steroid injection.

Identification and antibiotic susceptibility evaluation of Mycoplasma synoviae isolated from chickens in central China

Mycoplasma synoviae (M. synoviae) infections have become an increasingly serious concern in China because they cause huge economic losses to the poultry industry. Antibiotic treatment is one of control strategies that can be used to contain clinical outbreaks in M. synoviae-free flocks, especially because the bacteria can be transmitted through eggs. To understand M. synoviae infection status in farms of central China and the antibiotic susceptibility of the circulating strains in vivo and in vitro, 485 samples were collected from five provinces from 2019 to 2021. Fifty-two strains were isolated and identified. Determination of the minimum inhibitory concentration (MIC) of eight antibiotics (tylvalosin, tiamulin, tilmicosin, lincomycin, enrofloxacin, chlortetracycline, doxycycline and tylosin) for isolates showed that tylvalosin, doxycycline and tiamulin were effective against 52 clinical isolates (MIC values ≤ 0.0625–0.25 μg/mL, ≤0.0625–1 μg/mL, and 0.25–2 μg/mL, respectively). Tilmicosin, enrofloxacin and lincomycin had high MIC90 values (>32 μg/mL). An artificial M. synoviae infection model was established in chickens for evaluation of the short-term therapeutic effect of these antibiotics. After 5 days of medication, doxycycline (200 mg/L) showed a superior ability to inhibit M. synoviae compared with other groups, as did tylvalosin (200 mg/L). Furthermore, the therapeutic efficacy of tylvalosin (0.4 μg/mL) on intra-embryo-injected M. synoviae was higher than that of tiamulin at the same dose. A combination of MIC values determined in vitro and therapeutic effects observed in vivo revealed that tylvalosin and doxycycline had the best therapeutic effects. Tylvalosin also showed better inhibitory effects on the vertical transmission of M. synoviae than tiamulin.

Changes and Treatment Prognosis of Aqueous Humor Cytokine Concentrations of Patients with Acquired Immune Deficiency Syndrome Complicated by Cytomegalovirus Retinitis.

Purpose: The purposes of this study were to investigate cytokine changes in the aqueous humor after treatment of acquired immune deficiency syndrome (AIDS) complicated with cytomegalovirus retinitis (CMVR) and to determine whether these changes are useful prognostic indicators. Methods: This study included 12 patients (15 eyes) undergoing treatment for AIDS and CMVR. The patients received intravitreal injections and systemic intravenous treatment with ganciclovir and foscarnet sodium. The aqueous humor of each eye was sampled before treatment and before the third and fifth injections. The samples were tested to determine the concentrations of each of 27 cytokines using the Luminex 200™ liquid phase chip. Results: The concentrations of cytokines interleukin (IL)-1rα (P = 0.002), IL-1b (P = 0.001), IL-8 (P = 0.001), basic fibroblast growth factor (bFGF) (P < 0.001), interferon γ-induced protein 10 (IP-10) (P = 0.001), and tumor necrosis factor (TNF)-α (P = 0.004) in the aqueous humor before the third and fifth injections were significantly lower after than before treatment. The reductions in TNF-α (P = 0.028) and IL-1b (P = 0.028) concentrations after treatment were statistically significant compared with the postoperative visual acuity improvement (≥3 lines and <3 lines). The difference in TNF-α (P = 0.018) level before and after treatment (the difference between before treatment and before the fifth intravitreal injection) was also statistically significant compared with the number of injections (≥6 times and <6 times). Conclusion: The cytokines IL-1rα, IL-1b, IL-8, bFGF, IP-10, and TNF-α may offer new avenues for evaluation of therapeutic effect, and TNF-α and IL-1b may be important cytokines for prognostic evaluation (based on visual acuity and the number of injections) in patients suffering from AIDS and CMVR. Clinical Trial Registration: Number: ChiCTR2200056955.

A novel surgical technique in transforaminal lumbar interbody fusion by the bone graft delivery device: evaluation of therapeutic effect in patients with minimally invasive spine surgery

BackgroundTransforaminal Lumbar Interbody Fusion (TLIF) is commonly associated with higher complications and longer operative time. This study aims to evaluate the effectiveness, safety, and usability of a novel minimally invasive surgery (MIS) bone graft delivery device.Methods73 consecutive patients with lumbar spondylosis, degenerative disc disease, spondylolisthesis, scoliosis or trauma were enrolled in this randomized controlled trial. Group 1 comprised 39 patients treated with the novel MIS bone graft delivery device. Group 2 consisted of 34 patients treated with the conventional system. The primary objective of the study was the assessment of the amount of bone graft delivery using the device. The secondary objectives were the effect of the device on operative time, pain relief, disability improvement, and bone fusion grade.ResultsBone delivery amount was significantly higher in the MIS device group (6.7 ± 2.9 mL) compared to the conventional group (2.3 ± 0.5 mL), p < 0.001. Regarding the operation time, the MIS device group was associated significantly lower duration than the conventional group (p < 0.001). After a 3-month follow-up, 39.5% of the patients in the MIS device group and 3.5% of the patients in the conventional group were observed to achieve grade I fusion (complete fusion). There was a significant difference in fusion success rates (p < 0.01).ConclusionThe novel MIS bone graft delivery device was associated with successful bone delivery. Our MIS device provides promising modality with less operative time and higher bone fusion rates than conventional modalities.Trial Registration This trial was retrospectively registered on ClinicalTrials.gov (Registration date: 11/19/2021; Registration number: NCT05190055).

Evaluation of therapeutic effects of an herbal mixture (Echinacea purpurea and Glycyrrhiza glabra) for treatment of clinical coccidiosis in broilers.

Avian coccidiosis is thought to be one of the most expensive infectious diseases in the poultry industry. Safe and alternative anti-coccidial drugs are herbal extracts because they do not result in tissue residue and drug resistance. The objective of the present study was to evaluate the anti-coccidial effect of the herbal mixture, a complex of two plants (Echinacea purpurea, Glycyrrhiza glabra) in broiler chickens in comparison with toltrazuril. One hundred twenty broiler chickens were used in this experiment and divided into 4 equally numbered groups. All the groups, except Group D, were experimentally infected with mixedEimeriaspp. (E. Tenella, E. maxima,E. necatrixandE. brunetti) on day 14. Group A treated with an herbal mixture [Glycyrrhiza glabra Extract 5% (standardised to 5.4% glycyrrhizic acid) and Echinacea purpurea Extract 2% (standardised to 4% total phenolic content based on chlorogenic acid); Coxinin-EC® ; Shamim Teb Sepid Giti]. Group B treated with toltrazuril. Group C was experimentally infected with mixedEimeriaspp. but they did not have any treatment, this group was our positive control. Performance indices, faecaloocyst excretion, and intestinal lesion score were determined during the experiment. Positive control group had the poorest results and more mortality than other groups. Group D was not infected and was healthy all the experiment period. Treatment with herbal complex significantly reduced the negative performance and pathogenic effects associated with Eimeria spp. at a level that was comparable with toltrazuril. In summary, the anti-coccidial activity of the studied herbal complex suggests its use as an alternative anti-coccidial agent to chemotherapeutic drugs for controlling coccidiosis in poultry. -Coccidiosis is an important infectious disease that causes serious financial loss to the poultry industry. -Chemical anti-coccidial drugs and vaccines are the main control strategies to combat the disease. However, these tools have some constraints. -Herbal remedies are suitable alternatives to chemical compounds for control of losses associated with coccidiosis in poultry. -An herbal mixture (Echinacea purpurea, Glycyrrhiza glabra) has promising effects for controlling of coccidiosis in broiler chickens.

Evaluation of therapeutic effects of crocin in attenuating the progression of diabetic nephropathy: a preliminary randomized triple-blind placebo-controlled trial

BackgroundDiabetic nephropathy (DN) is one of the most important complications of type 2 diabetes (T2DM). Oxidative stress and inflammatory cytokines play an essential role in the development and progression of DN. Despite adopting appropriate therapies, many patients with DN progress to end-stage renal disease (ESRD). Therefore, exploring innovative strategies for better management of DN is crucial. Crocin, a natural compound found in saffron, has profound antioxidant, antifibrotic and anti-inflammatory properties. This study aimed to evaluate the therapeutic effects of crocin in attenuation of the progression of DN.MethodsIn this randomized, triple-blind, placebo-controlled clinical trial, 44 patients with T2DM and microalbuminuria were randomly assigned to receive either crocin (15 mg/day) or a placebo for 90 days. Eventually, 40 patients completed the study: 21 patients in the crocin group and 19 in the placebo group. The primary outcome was a change in urine Albumin-to-Creatinine Ratio (uACR) from baseline to the end of the treatment period. We also evaluated metabolic, anthropometric, and biochemical parameters as the secondary outcomes.ResultsThe results of the present study showed that uACR increased in both groups, but the increment was not significantly higher in the crocin group compared with the placebo. Serum levels of transforming growth factor-β (TGF-β) decreased in the crocin group and increased in the placebo group, but none of these changes was significant. Crocin significantly reduced triglyceride (TG) as an important metabolic parameter (P-Value = 0.03).ConclusionThis study has shown that crocin may be a safe and potential adjunct to conventional therapies for DN patients but because of our limitations such as short duration of the treatment period, and prescribing low doses of crocin, we could not achieve the significant level.

DNA Zipper Mediated Membrane Fusion for Rapid Exosomal MiRNA Detection.

Accurate and reliable detection of exosomal miRNA can serve as a promising method for early diagnosis of disease and evaluation of therapeutic effects. However, current exosomal miRNA detection methods commonly involve exosome enrichment, containing RNA extraction, and qRT-PCR based quantification, which are expensive and time-consuming. Herein, we develop a DNA zipper-mediated membrane fusion approach for rapid exosomal miRNA detection and cancer diagnosis. First, a lipid vesicle probe containing miR21-targeting molecular beacons (MBs) is constructed and further loaded with zipper DNA constructs (ZDCs) on its surface. Meanwhile, complementary zipper DNA constructs (cZDCs) are introduced on the exosome of interest. Upon mixing them together, zipping between ZDC and cZDC induces the membrane fusion of exosomes and vesicle probes, triggering the recognition of exosomal miR21 by contained MBs and fluorescence emission that can be conveniently detected within 30 min. Importantly, with the assistance of flow cytometry, miR21-overexpressed tumor exosomes derived from either cell culture medium or clinical patient serums can be distinguished from exosomes secreted from normal cells. This approach provides a convenient way to accurately detect the exosomal miRNA, which may hold great potential in liquid biopsy for early cancer diagnosis and monitoring the therapeutic effects during the treatments.

Evaluation of therapeutic and prophylactic effectiveness of levofloxacin in experimental colibacillosis of chickens with regard to infecting dose

The goal of the present research was to investigate therapeutic and prophylactic effectiveness of levofloxacin following experimental challenge of chickens with varying doses of Escherichia сoli namely 1 minimum lethal dose (DLM) and 4 minimum lethal doses (DLM). We conducted two experiments on two-day-old Hisex Brown chickens. For the first experiment we used 6 groups of chicks (n = 25, in each group). The drug was administered via drinking water (with free access) 24 hours before the challenge. Chicks of Groups 1 to 4 received levofloxacin via drinking water at concentrations 50 mg/L, 100 mg/L, 200 mg/L and 300 mg/L for 5 days. Group 5 was control, Group 6 was intact. The chicks were challenged with 1.5 х 108 E. сoli bacterial cells per 0.5 mL (1 minimum lethal dose (DLM)) intraperitoneally. The second experiment was conducted similarly but the infecting dose was increased by 4 times (4 minimum lethal doses (DLM)).Administration of levofloxacin at concentration 300 mg/L both in the first experiment, when the infecting dose was 1 minimum lethal dose, and in the second experiment, when the infecting dose was 4 minimum lethal doses, proved that the drug has the same high therapeutic and prophylactic effectiveness of 96 %. Administration of the drug at concentration 200 mg/L showed 100 % effectiveness in the first experiment. But in the second experiment levofloxacin at the same concentration ensured survival of only 88 % of the challenged chicks. When the drug was administered at concentration 100 mg/L we observed reliable change in indices. Accordingly in the first experiment 88 % of the chicks survived. In the second experiment, when the infecting dose increased to 4 minimum lethal doses, only 52 % of the chicks survived. Administration of levofloxacin at concentration 50 mg/L did not show significant therapeutic effect.

A new droplet digital PCR assay: improving detection of paucibacillary smear-negative pulmonary tuberculosis

ObjectivesSmear-negative pulmonary TB (PTB) is difficult to diagnose. Current diagnosis and treatment monitoring methods have inherent limitations. Droplet digital PCR (ddPCR) is a new technique with high sensitivity. This study presents a novel ddPCR for rapid and sensitive identification of Mycobacterium tuberculosis (MTB). MethodsMTB DNA was detected in respiratory specimens from suspected PTB cases using ddPCR assay, which was directed at two different locations within IS6110. We, for the first time, evaluated the clinical diagnostic ability of this ddPCR for paucibacillary smear-negative PTB. ResultsA total of 605 PTB suspects were recruited, including 263 patients with confirmed PTB (84.03% from smear-negative PTB) and 342 without PTB. The sensitivity and specificity of IS6110 ddPCR were 61.22% (95% confidence interval (CI) 55.00-67.10%) and 95.03% (95% CI 92.20-97.10%) for total PTB and 57.92% (95% CI 51.10-64.50%) and 94.57% (95% CI 91.20-96.90%) for smear-negative PTB. ddPCR assay outperformed Xpert MTB/RIF (53.08% vs 28.46%, P = 0.020) in smear-negative PTB detection. Furthermore, effective anti-TB treatment was linked to significantly lower IS6110 copies detected by ddPCR. ConclusionHerein, we developed and validated a highly sensitive and robust ddPCR assay for MTB quantification in respiratory specimens, which improves diagnosis and therapeutic effect evaluation of smear-negative PTB.

Evaluating short-term outcomes of the value of sound touch elastography (STE) following the treatment for Budd–Chiari syndrome (BCS): a case series study

To investigate the value of sound touch elastography (STE) in the evaluation of short-term therapeutic effect of Budd-Chiari syndrome (BCS) by measuring liver stiffness (LS), and in addition, to analyse the relationships between liver function, pressure gradient of the hepatic veins, and LS. A case series study was conducted at Affiliated Hospital of Xuzhou Medical University from August 2020 to December 2020. Patients diagnosed with BCS were recruited prospectively and grouped according to Child-Pugh grade before endovascular therapy. LS was measured using STE before and after therapy. Comparisons between the LS and hepatic venous pressure gradient (HVPG) changes of patients were tested with paired sample t-tests. A total of 46 patients (23 males and 23 females) were included in this study. According to the Child-Pugh scoring criteria, 24 patients were classified as grade A, 16 as grade B, and 6 as grade C. LS was significantly different between the three groups (F=127.01, p<0.001). Post-treatment LS was significantly lower than pre-treatment (p<0.001). The mean HVPG before treatment was 13.02±3.82 mmHg and decreased after intervention (p<0.001). The STE is a potential tool for evaluating short-term therapeutic effect of BCS patients.

Research and Development of Preclinical Overhauser-Enhanced Magnetic Resonance Imaging.

Significance: Imaging free radicals, including reactive oxygen species and reactive nitrogen species, can be useful for understanding the pathology of diseases in animal disease models, as they are related to various physiological functions or diseases. Among the methods used for imaging free radicals, Overhauser-enhanced magnetic resonance imaging (OMRI) has a short image acquisition time and high spatial resolution. Therefore, OMRI is used to obtain various biological parameters. In this study, we review the methodology for improving the biological OMRI system and its applications. Recent Advances: The sensitivity of OMRI systems has been enhanced significantly to allow the visualization of various biological parameters, such as redox state, partial oxygen pressure, and pH, in different body parts of small animals, using spin probes. Furthermore, both endogenous free radicals and exogenous free radicals present in drugs can be visualized using OMRI. Critical Issues: To acquire accurate biological parameters at a high resolution, it is essential to increase the electron paramagnetic resonance (EPR) excitation efficiency and achieve a high enhancement factor. In addition, the size and magnetic field strength also need to be optimized for the measurement target. Future Directions: The advancement of in vivo OMRI techniques will be useful for understanding the pathology, diagnosis, and evaluation of therapeutic effects of drugs in various disease models.
