Development of Oleogel-Based Fat Replacer and Its Application in Pan Bread Making.

In recent years, the bakery industry has been exploring alternative fats to replace traditional solid fats. Shortening, a common baking ingredient, is produced through the hydrogenation of vegetable oils, resulting in high levels of saturated and trans fatty acids, despite its vegetable oil origin. The excessive consumption of these fats has been associated with negative health effects, including dyslipidemia and cardiovascular issues. Oleogels, incorporating hydroxypropyl methylcellulose (HPMC), xanthan gum (XG), and olive oil, were utilized to replace shortening in the production of white pan bread. The substitution of shortening with oleogel in the white pan bread preparation demonstrated potential reductions in saturated fat, trans fat, and the ratio of saturated fat to unsaturated fatty acids. Specifically, with the complete substitution of shortening with oleogel, saturated fatty acids decreased by 52.46% and trans fatty acids by 75.72%, with unsaturated fatty acids increasing by 57.18%. Our findings revealed no significant difference in volume between bread made with shortening and bread with up to 50% shortening substitution. Moreover, when compared to bread made with shortening and 50% oleogel substitution, no adverse effects on the quality characteristics of volume and expansion properties were observed, and the retrogradation rate was delayed. This study suggests that incorporating oleogels, formed with hydrocolloids such as HPMC and XG, to replace shortening in bread, in conjunction with traditional solid fats, provides positive effects on the quality and nutritional aspects of the bread compared to using oleogel alone. Through this study, we demonstrate the use of oleogels as a healthier alternative to shortening, without reducing the bread's quality, thus offering a practical solution to reduce unhealthy fats in bakery products.

The clinical efficacy of preoperative flash visual evoked potential (VEP) for mature cataracts without a response to pattern VEP.

BACKGROUND: This study aims to assess the effectiveness of the preoperative flash visual evoked potential (VEP) test in predicting postoperative visual acuity for monocular mature cataract cases when compared to the contralateral normal eye. METHODS: The study included 60 patients, each with a monocular mature cataract diagnosis, who underwent preoperative flash VEP testing showing no pattern VEP response. Subsequently, phacoemulsification was performed. The relationship between the flash VEP test latency values (P1, N2, P2) and amplitude value (N2-P2), and the degree of visual acuity recovery 3 months post-cataract surgery, was evaluated using the LogMAR scale. Furthermore, a linear regression analysis was conducted to explore the connection between preoperative flash VEP components and postoperative visual acuity. RESULTS: The average age of the patients was 65.4 ± 13.6 years, with a range of 43 to 87 years. The study included 36 males and 24 females. A significant disparity in visual acuity was observed between the preoperative and 3-month postoperative stages (p < 0.001). The preoperative flash VEP test for mature cataracts revealed significant delays in P1, N2, and P2 latency, as well as a reduction in N2-P2 amplitude potential when compared to the contralateral normal eye (p < 0.001). Notably, delayed P2 latency and reduced N2-P2 amplitude potential were particularly indicative of poor visual acuity prognosis after cataract surgery in the multiple regression analysis (p < 0.05). The N2-P2 amplitude potential was the important value that exhibited statistically significant results, with an area under the curve (AUC) of 80% sensitivity and 88% specificity, using a cutoff value of 6.07 µV. CONCLUSIONS: In cases of monocular mature cataract, a reduction in N2-P2 amplitude potential compared to the contralateral normal eye emerged as the most reliable predictor of postoperative visual prognosis following cataract surgery.

Comparative outcomes of the pathogen in cultured Jones tubes used in lacrimal bypass surgery according to follow up periods.

AIM: To evaluate the pathogens in cultured Jones tubes used in lacrimal bypass surgery according to the postoperative periods and to obtain data for the prevention of infection of functional lacrimal stent invention. METHODS: Totally 71 patients (81 eyes) who underwent the removal of Jones tubes were enrolled in study. All the removed Jones tubes were cultured for bacterial and fungal identification and tested for bacterial antibiotic sensitivity. The results were analyzed according to the duration of the inserted Jones tube after lacrimal bypass surgery. RESULTS: Of the 81 eyes, bacteria were isolated from 69 eyes (85.2%) and fungi from 6 eyes (7.4%). Among 69 eyes, 40.6% showed Staphylococcus aureus (S. aureus), 11.6% were Pseudomonas aeruginosa (P. aeruginosa). Gram-positive bacteria were isolated more than Gram-negative bacteria, but Gram-negative bacteria showed a higher incidence in the Jones tube implanted for over 10y (P=0.035). The antibiotic sensitivity test showed that 46.4% of S. aureus were resistant to oxacillin. In terms of antibiotics commonly used in ocular clinical practice, vancomycin was sensitive to S. aureus and Streptococcus pneumoniae (S. pneumoniae), amikacin responded to P. aeruginosa and Proteus mirabilis (P. mirabilis). Trimethoprim/sulfamethoxazole (TMP/SMX) was all sensitive to S. aureus, S. pneumoniae and P. mirabilis except P. aeruginosa. CONCLUSION: S. aureus is the most commonly found organism in the Jones tube after lacrimal bypass surgery, and 46.4% of them are methicillin-resistant S. aureus (MRSA), sensitive to vancomycin. Especially, P. mirabilis responded with amikacin is dominantly detected in the Jones tubes implanted for more than 10y.

Enhanced stabilization of oil-in-water (O/W) emulsions by fibrillar gel particles from lentil proteins.

Pulse proteins as a sustainable protein source have attracted increasing interest in food development, but pulse proteins are generally less surface active than dairy proteins. This work introduces lentil protein (LP)-based fibrillar gel particles (FGPs) fabricated from heat-induced LP fibrillar aggregates by 1, 4, 8, and 16 h of heating, followed by particle reduction using sonication. The heating time significantly impacts the FGPs particle size and surface hydrophobicity. The FGP prepared by 4 h of heating (FGP-4) showed a small size (<200 nm) and homogeneous size distribution while possessing significantly increased surface hydrophobicity compared to untreated LP. Such structural features made FGP-4 better adsorb at the O/W interface and then completely covered the oil droplet surface, leading to homogeneous emulsions of small size (22.33 µm) and superior long-term stability without creaming for 30 days. In addition, the dispersed FGP in the bulk phase could develop interactions among each other, leading to improved emulsion viscosity and texture without oil droplet size change. This finding suggests that constructing fibril-type gel particles can provide a new strategy for forming superior O/W emulsions with improved stability from plant proteins.

Influence of different electrolytes and oils on the stability of W1/O/W2 double emulsion during storage and in vitro digestion.

The aim of this study is to formulate a stable water-in-oil-in-water (W1/O/W2) double emulsion using different types of oils and electrolytes. W1/O was formulated with different electrolyte solutions (W1) dispersed in various oils (O) using polyglycerol polyricinoleate as a stabilizer. External aqueous phase was Tween-80 (W2), and W1/O dispersed in W2 was used. The emulsion containing NaCl or MgCl2 exhibited high encapsulation efficiency (EE) and maintained particle size. Regarding the oil type, the emulsion with MCT oil showed a small droplet size and a high viscosity and EE, presenting a stable droplet distribution in optical observation. The stability of emulsion containing NaCl was maintained during the in vitro digestion experiments. MCT oil, NaCl and MgCl2 have the potential to produce stable double emulsions for storage stability and in vitro digestion studies. The findings would be useful for preparing stable double emulsions used in the food and cosmetic industries.

Clinical characteristics and risk factors for visual prognosis according to the types of infectious endophthalmitis.

BACKGROUND: Endophthalmitis is a fatal ophthalmological emergency that needs prompt diagnosis and treatment. This study aimed to evaluate the clinical characteristics and investigate risk factors for the visual prognosis of the different types of endophthalmitis. METHODS: This retrospective study included 239 eyes diagnosed with endophthalmitis at the Pusan National University Hospital between January 2006 and December 2020. All patients were classified into six groups based on the etiology of endophthalmitis: post-cataract surgery, post-vitrectomy, post-glaucoma surgery, post-intravitreal injection, endogenous, and post-trauma. Demographics and clinical characteristics such as age, sex, laterality, initial symptoms, the interval between the primary causable event and diagnosis of endophthalmitis, initial and final visual acuity, management, and culture results were reviewed and statistically analyzed. Risk factors for poor visual prognosis were also analyzed according to the type of endophthalmitis. RESULTS: Of the 239 cases of endophthalmitis, the most common cause was post-cataract surgery, that occurs within two weeks post-surgery. Gram-positive Staphylococcus was cultured most frequently. Fusarium was characteristically cultured from delayed post-cataract surgery endophthalmitis (14 days-6 weeks post-surgery). Post-vitrectomy endophthalmitis occurred within 3.3 days post-surgery, but post-glaucoma surgery endophthalmitis developed a long period after surgery, averaging 2,742 days. Post-intravitreal injection endophthalmitis occurred most frequently following bevacizumab injection, and Staphylococcus was most commonly isolated. For endogenous endophthalmitis, the pyogenic liver abscess was the most common underlying disease, and Klebsiella was isolated most frequently. Post-traumatic endophthalmitis mostly occurred in young men. Advanced age and poor initial visual acuity were risk factors for poor visual prognosis (P = 0.041, odds ratio = 1.024 and P < 0.001, odds ratio = 3.904, respectively, using logistic regression analysis). CONCLUSION: Advanced age and initial visual acuity were risk factors for poor visual prognosis in cases of endophthalmitis caused by various etiologies. Early diagnosis and treatment of endophthalmitis are required, especially in older patients.

Physico-Chemical Properties and Storage Stability of an Emulsion as a Fat Replacer in Meat Analogs during the Freezing Storage.

This study determined the effects of physicochemical and microbial properties of emulsion as a fat replacer in meat analogs during freezing storage. Meat analogs were prepared with different fat replacers: vegetable oil (O) for control, oil in water emulsion (E), and non-emulsified oil in water emulsion (EC) for emulsion control. After that, meat analogs were stored for 0.5, one, three, and six months at −18 °C and −60 °C. The results showed that the drip loss of all samples was not significantly different (p > 0.05). However, the liquid holding capacity of EC and E was significantly higher than that of O (p < 0.05). Additionally, the microstructures of meat analogs of E and EC were smaller with denser pore sizes than O. This explains the significantly lower hardness of E and EC compared to O (p < 0.05). Overall, E showed superior physiochemical and sensory quality. During the storage, the stability of chemical properties, such as volatile basic nitrogen and thiobarbituric acid reactive substances, showed no significant changes (p > 0.05). Moreover, the microbial studies (total viable counts and Escherichia coli count) suggested that meat analogs did not deteriorate during the preparation and storage. Thus, this study suggests that emulsion-type fat replacers influence meat analogs' physicochemical and sensorial properties. However, these properties are not influenced by the storage temperature and duration.

Clinical efficacy of 0.05% cyclosporine nano-emulsion in the treatment of dry eye syndrome associated with meibomian gland dysfunction.

AIM: To evaluate the clinical efficacy of topical 0.05% cyclosporine nano-emulsion in the treatment of dry eye syndrome (DES) with meibomian gland dysfunction (MGD). METHODS: This prospective study included 64 patients with DES and MGD who were randomly assigned to three groups: Group 1 (n=24, conventional cyclosporine), Group 2 (n=21, nano-emulsion cyclosporine), and Group 3 (n=19, control). Lid margin telangiectasia (LMT), meibomian gland secretion (MGS), conjunctival injection (CI), corneal staining (CS), tear break-up time (TBUT), Schirmer test I (STI), Ocular Surface Disease Index (OSDI), and lipid layer thickness (LLT) was evaluated at 4, 8, and 12wk of treatment. RESULTS: In Group 3 (control), LMT, CS, and CI improved after 8wk, MGS, TBUT after 12wk of treatment. In Group 1 (conventional cyclosporine), LMT, MGS, and TBUT improved significantly after 4wk, whereas CS, CI, STI, and LLT improved significantly after 8wk, and OSDI at 12wk. In Group 2 (nano-cyclosporine), LMT, MGS, CS, CI, TBUT, and OSDI significantly improved after 4wk, and STI after 8wk. Especially, LLT was significantly higher than other groups after 4wk. CONCLUSION: Cyclosporine and nano-cyclosporine shows significant improvement in DES with MGD than the control group. In contrast, the nano-cyclosporine group shows more statistically improved CI and CS at 4wk, especially LLT at 4, 8, and 12wk compared to the conventional cyclosporine group.

Effects of Glucono-δ-Lactone and Transglutaminase on the Physicochemical and Textural Properties of Plant-Based Meat Patty.

Due to growing interest in health and sustainability, the demand for replacing animal-based ingredients with more sustainable alternatives has increased. Many studies have been conducted on plant-based meat, but only a few have investigated the effect of adding a suitable binder to plant-based meat to enhance meat texture. Thus, this study investigated the effects of the addition of transglutaminase (TG) and glucono-δ-lactone (GdL) on the physicochemical, textural, and sensory characteristics of plant-based ground meat products. The addition of a high quantity of GdL(G10T0) had an effect on the decrease in lightness (L* 58.98) and the increase in redness (a* 3.62). TG and GdL also decreased in terms of cooking loss (CL) and water holding capacity (WHC) of PBMPs. G5T5 showed the lowest CL (3.8%), while G3T7 showed the lowest WHC (86.02%). The mechanical properties also confirmed that G3T7-added patties have significantly high hardness (25.49 N), springiness (3.7 mm), gumminess (15.99 N), and chewiness (57.76 mJ). The improved textural properties can compensate for the chewability of PBMPs. Although the overall preference for improved hardness was not high compared to the control in the sensory test, these results provide a new direction for improving the textural properties of plant-based meat by using binders and forming fibrous structures.

User-demand fast-curable ocular glues enforced by multilength tunable networks.

Achieving fast and secure wound closure without ocular foreign body sensation is highly desired in ophthalmologic surgery. Sutureless approaches using tissue adhesives are gaining popularity, but their practical use is limited by the difficulty in controlling adhesion time and satisfying safety standards without compromising adhesive performance. Herein, we report user-demand hydrogel-forming ocular glues based on multilength photo-crosslinkable hyaluronic acid (HA), achieving firm tissue adhesion under wet and dynamic conditions and possessing cornea-like optical transparency. The HA-based photocurable glue (HA photoglue) quickly seals wounds upon nontoxic low-energy light exposure (320-500 nm, < 5 s, < 1 J cm-2), and its mechanical and adhesive properties are improved by introducing short and long crosslinkable moieties into HA through one-step synthesis, forming multilength networks. Furthermore, the HA photoglue provides stable sealing in wet environments like ocular mucous surface, a clear vision with a light transmittance of more than 95% over the entire visible range, and a lubricating surface with minimal ocular sensation (generating less than 10% frictional force than suture groups). In a rabbit corneal incision model, the HA photoglue showed improved wound healing efficacy based on histological evaluation compared to control groups.

Temporary blindness caused by corneal edema after a local anesthetic injection in the eyebrow region: a case report.

Plastic surgery around the eyes is usually performed under local anesthesia, using a mixture of lidocaine and epinephrine. Blindness is a rare but devastating complication after the injection of local anesthesia in this region. Most cases reported to date have been caused by occlusion of the ophthalmic artery or central retinal artery. In this case report, however, we present a highly unusual case of blindness caused by corneal edema after a local anesthetic injection. A patient visited the emergency room with a laceration on the eyebrow, and local anesthesia was injected before suturing. Immediately after the injection, severe corneal edema developed, making it impossible to observe the structures in the anterior chamber in detail or check the light reflex and visual acuity of the naked eye. An antibiotic (moxifloxacin hydrochloride) and high-concentration steroid eyedrops were promptly applied. High-concentration steroids were also administered orally. On day 13 post-injury, the visual acuity of the naked eye improved to 1.0, and no recurrence of corneal lesions was observed. Although the cause of corneal edema after the local injection could not be conclusively identified, we hope that this report will help raise clinicians' awareness of this complication and appropriate treatment methods.

Evaluation of the safety of anterior capsule staining with trypan blue under air: a retrospective analysis.

AIM: To evaluate the safety of using 0.03% trypan blue under air for anterior capsule staining in cataract surgery. METHODS: The current study involved a retrospective analysis of the medical records of 86 patients with vitreous hemorrhage, who underwent pars plana vitrectomy and cataract surgery. The patients were classified into two groups. The trypan blue group (n=45) comprised patients who underwent anterior capsule staining with 0.03% trypan blue under an air bubble. The control group (n=41) comprised of patients who underwent intracameral illuminator-assisted capsulorhexis. The status of endothelial cell density (ECD) in both the groups was analyzed. RESULTS: The trypan blue group displayed significant decline in ECD at 1mo (7.91% loss, P<0.001) and 3mo (9.65% loss, P<0.001) after the surgery, whereas no significant changes were observed in the control group. Moreover, the number of patients who did not display a postoperative decline in ECD was significantly higher in the control group (43.9%; 18 patients) than in the trypan blue group (17.1%; 7 patients, P=0.004). CONCLUSION: Anterior capsule staining with trypan blue under the air bubble would not be as safe as the intracameral illuminator. The ECD loss might be attributed to the air bubble rather than to the deleterious effects of 0.03% trypan blue. Further studies are required to clarify this.

Development of a Stepwise Algorithm for Supercooling Storage of Pork Belly and Chicken Breast and Its Effect on Freshness.

Supercooling is the method of lowering the temperature of a foodstuff below its freezing point without phase transitions. This storage technique has a potential advantage for extending shelf life. Nevertheless, the supercooled state of food is thermodynamically unstable. To accomplish supercooling storage, slow cooling rate and minimized temperature fluctuation are necessary. Thus, a stepwise cooling algorithm was designed and applied in this study. Pork belly and chicken breast were stored at 3 °C, -18 °C (freezing), and supercooling treatment was applied to them for 12 days. All samples preserved their supercooled state and were unfrozen during the storage period. Overall, supercooled samples were advantageous in respect of drip loss compared to that of frozen samples, regardless of type of sample. Total volatile basic nitrogen, total aerobic account, and cooking loss of pork belly was higher than in the chicken breast due to the high fat retention in pork belly as compared to chicken breast, in particular, at refrigerated storage condition. Samples stored at supercooling treatment prevented increase in volatile basic nitrogen and microbial growth. Therefore, the supercooled state was successful when using stepwise algorithm, and it was effective at maintaining meat quality compared to freezing and refrigeration storage.

Corneal endothelial cell damage after scleral fixation of intraocular lens surgery.

PURPOSE: To analyze corneal endothelial cell damage after scleral fixation of intraocular lens (SFIOL) surgery. STUDY DESIGN: Retrospective study. METHODS: Medical records of consecutive eyes undergoing SFIOL surgery performed by a single surgeon were reviewed between January 2011 and June 2019. The patients were classified into three groups according to surgical methods: Group I, re-fixating the existing intraocular lens (IOL) or fixating a new IOL in an aphakic eye; Group II, removing the existing IOL and fixating a new IOL; and Group III, phacoemulsification and fixating a new IOL simultaneously. Preoperative and postoperative specular microscopy (SM) status were compared. Changes in SM were compared among the three groups. RESULTS: Ninety-four eyes were included. Thirty-four eyes in Group I, 39 in Group II, and 21 in Group III. The endothelial cell density (ECD) loss in Group I was 1.5%, less than the ECD loss of 14.3% (p < 0.001) in Group II and 15.4% (p = 0.005), in Group III. In no eye was there an ECD decrease to < 1000/mm2 following the surgical procedure. CONCLUSIONS: ECD loss was related to IOL removal or phacoemulsification rather than SFIOL surgery. SFIOL using the existing IOL should be considered preferential in eyes with low ECD and dislocated IOL.

Application of Liposome Encapsulating Lactobacillus curvatus Extract in Cosmetic Emulsion Lotion.

Probiotic extracts have various positive attributes, such as antioxidant, tyrosinase inhibitory, and antimicrobial activity. Lactobacillus curvatus produces bacteriocin, which activates the lipid membrane structure and has potential as a natural preservative for cosmetic emulsions. In this study, L. curvatus extract was encapsulated in liposomes and formulated as an oil-in-water (O/W) emulsion. Radical scavenging activity, tyrosinase inhibition, and challenge tests were conducted to confirm the liposome activity and the activity of the applied lotion emulsion. The liposome-encapsulated extract had a relatively high absolute ζ-potential (52.53 > 35.43), indicating its stability, and 96% permeability, which indicates its potential as an active agent in lotion emulsions. Characterization of emulsions containing the liposomes also indicated a stable state. The liposome-encapsulated extract exhibited a higher radical scavenging activity than samples without the extract and non-encapsulated samples, and the functionality was preserved in the lotion emulsion. The tyrosinase inhibition activity of the lotion emulsion with the liposome-encapsulated extract was similar to that of the non-treated extract. Candida albicans and Aspergillus niger were also inhibited in the challenge test with the lotion emulsions during storage. Collectively, these findings indicate that the liposome-encapsulated extract and the lotion containing the encapsulated extract have potential applicability as natural preservatives.

Effects of dietary high dose DHA omega-3 supplement in dry eye with meibomian gland dysfunction.

AIM: To evaluate the clinical efficacy of dietary supplement of high dose DHA omega-3 in dry eye with meibomian gland dysfunction (MGD). METHODS: Prospective randomized double-masked, placebo-controlled clinical trial was conducted in mild to moderate dry eye patients with MGD. Patients have no history of taking any dietary omega-3 supplements before 3mo. Patients were divided into two groups: 24 patients in the omega-3 group and 26 patients in the placebo group. The omega-3 group received two capsules of Easyeye Dry®, total containing 600 mg of EPA and 1640 mg of DHA, while the placebo group received two capsules containing 3000 mg of olive oil. All patients take two pills once a day. The examination of MGD scores, tear break-up time (TBUT), corneal staining test (NEI), strip meniscometry (SM tube), and ocular surface disease index (OSDI) scores were performed at baseline, after 4 and 8wk. RESULTS: A total of 50 patients were included. There were no differences in baseline characteristics between the two groups, such as age, sex, and other ocular examination findings. The TBUT, NEI, and OSDI scores significantly improved after 4 and 8wk in both groups. While after 8wk TBUT (6.00±1.62s vs 5.08±1.28s, P=0.034) and MGD score (7.2±1.8 vs 8.1±2.6, P=0.033) in the omega-3 group was more significantly improved than that of the placebo group. CONCLUSION: Dry eye with the MGD patient, a high dose of DHA omega-3 dietary supplement can improve TBUT and MGD score after 8wk, effective in stabilizing the tear film.

Pterygium surgery by double-sliding flaps procedure: Comparison between primary and recurrent pterygia.

PURPOSE: This study aimed to evaluate the surgical outcomes of pterygial excision for primary and recurrent pterygia by a single method of pterygia excision combined with two conjunctival flaps. METHODS: This retrospective study divided 193 cases of pterygium into the primary (140 cases) and recurrent (53 cases) pterygium groups. Following double-sliding conjunctival transposition flap operation and surgical excision of the pterygium, the success and recurrence rates of pterygial surgery were assessed based on visual acuity and corneal and total astigmatism during follow-up at least 6 months. RESULTS: Both primary and recurrent pterygium groups showed significant improvements in visual acuity and astigmatism (corneal and total) between before and after this procedure. Total astigmatism and success rate of primary pterygium were significantly better than those for recurrent pterygium. Two cases (1.4%) of primary pterygium and four cases (7.5%) of recurrent pterygium developed recurrence, corresponding to a rate of 3.1% (6/193 cases). The success rates significantly make a difference between primary and recurrent groups but did not differ significantly between the first recurrent and over twice recurrent pterygium. However, visual acuity, cornea, and total astigmatism improved significantly after surgery in first recurrent group but not in over twice recurrent group. CONCLUSION: The double-sliding conjunctival flaps surgery appeared to be a useful method, with a better success rate and lower pterygial recurrence in pterygium surgery. Especially, when pterygium is larger or recurrent type, this technique can be easily covered the bare sclera, as compared to any transposition conjunctival flap operation.

Antioxidant activity of ß-cyclodextrin inclusion complexes containing trans-cinnamaldehyde by DPPH, ABTS and FRAP.

This study was carried out to observed ß-cyclodextrin (ß-CD) inclusion complexes containing trans-cinnamaldehyde (CIN) by using DPPH, ABTS and FRAP assay. Antioxidative ability was compared between pure CIN and ß-CD-CIN inclusion complexes and particle size, encapsulation efficiency, and temperature-dependent release of inclusion complexes were investigated. High concentration of ß-CD (1.8%) as well as guest oil 1:3 molar ratio (ß-CD:CIN) influenced on particle size bigger during self-assembly process. And particle sizes were increased as storage period. In the antioxidant capacity results, pure ß-CD (1.8%) was antioxidative without CIN especially at FRAP assay. Antioxidant activity dramatically increased after 1:1 molar ratio (1.8% ß-CD:CIN), especially at DPPH assay and ABTS•+ assay. In this study, ß-CD complexation enhanced CIN solubility and affected increase the antioxidant activity of the CIN. Moreover, we need to consider that molar ratio of between ß-CD concentration and CIN is effective manufacturing condition to improve antioxidant activity of ß-CD-CIN inclusion complexes.

Cross Sectional Study among Intraocular Pressure, Mean Arterial Blood Pressure, and Serum Testosterone according to the Anthropometric Obesity Indices in Korean Men.

PURPOSE: To investigate the association between intraocular pressure (IOP) and serum testosterone according to the severity of obesity. MATERIALS AND METHODS: We investigated the correlation of IOP-testosterone according to the anthropometric obesity indices, such as obesity index (OI), body mass index (BMI), and waist circumference to height ratio (WtHR). Each of the obesity indices was classified into three groups: normal, overweight, and obesity. In additional, the association of IOP-testosterone was compared between testosterone 3.0 ng/mL below and above. RESULTS: Total of 3,949 participants, the mean age was 58.86±10.06 years, mean IOP was 14.40±2.61 mmHg, mean arterial blood pressure (MAP) was 93.67±11.47 mmHg, and mean serum testosterone was 4.21±1.83 ng/mL. The association of MAP and IOP was significantly positively correlated according to the severity of obesity, but testosterone showed a significant negative relationship (p<0.05). IOP was significantly correlated with OI and BMI, but MAP and testosterone were correlated with all anthropometric obesity indices (p<0.05). The relationship of IOP and testosterone was significantly associated with only normal groups according to the degree of obesity (p<0.05). The IOP in patients with testosterone above 3.0 ng/mL was significantly higher than testosterone below 3.0 ng/mL (p<0.05). CONCLUSIONS: The correlation of IOP-testosterone has a significantly positive relationship, in case of healthy men with normal weight by OI or BMI.
