RESUMEN

BACKGROUND: Neonatal feces are one of the most important sources for probiotic isolation. The purpose of this study was the isolation and identification of Bifidobacterium spp. from neonatal feces and the evaluation of in vitro probiotic properties of strains including safety tests. RESULTS: A total of 40 isolates were obtained from 14 healthy newborns' feces in Erzurum province, Türkiye. By their rep-PCR patterns and 16S rRNA gene sequences, isolates were identified as 26 Bifidobacterium breve and 14 Bifidobacterium longum. Fifteen of the isolates tolerated bile salts and showed high resistance to simulated gastric juice. Isolates exhibited varying rates of auto-aggregation and hydrophobicity. In addition, most of the isolates displayed antibacterial activity against Escherichia coli O157:H7, Staphylococcus aureus ATCC 29213, Salmonella Typhimurium RSHMB 95091, and Pseudomonas aeruginosa ATCC 9027. However, only one strain showed bile salt hydrolase activity and two strains showed the ability to produce H2O2. Bifidobacterium strains were generally sensitive to the tested antibiotics and lacked kanamycin, gentamicin, and streptomycin resistance genes, and hemolytic and DNAse activities. On the other hand, it was determined that five strains had various virulence genes including gelE, esp, efaAfs, hyl, and ace. CONCLUSION: Results of the present study suggested that B. longum BH28, B. breve BH4 and B. breve BH5 strains have the potential as probiotic candidates for further studies. © 2024 The Authors.

RESUMEN

OBJECTIVE: The objective of this study was to investigate the protectiveness of resveratrol on cisplatin-induced damage to the ovary using experimental models. METHODS: A total of 30 female Wistar-Albino rats constituted the research material. The rats were categorized into three groups: Group 1 was administered one milliliter of 0.9% NaCl solution, Group 2 was administered 7.5 mg/kg cisplatin, and Group 3 was administered 7.5 mg/kg cisplatin and 10 mg/kg resveratrol. Ovaries were extirpated in all groups and subjected to biochemical and histopathological tests. Cisplatin-induced damage to ovarian tissue was graded and scored as the total histopathological findings score. The ovarian function was assessed using immunohistochemical staining for c-kit expression. Rats' malondialdehyde, catalase, and superoxide dismutase levels were determined. RESULTS: The histopathological finding score was significantly higher in Group 2 than in other groups (p<0.05). The superoxide dismutase and catalase levels were significantly higher in Group 3 than in Group 2 (p<0.001 for both cases). The malondialdehyde level was significantly higher in Group 2 than in Group 3 (p<0.001). CONCLUSION: The study findings demonstrated that resveratrol reduced ovarian injury and enhanced biochemical parameters following cisplatin-induced ovary damage in experimental models.

RESUMEN

Glycosylation of milk whey proteins, specifically the presence of sialic acid-containing glycan residues, causes functional changes in these proteins. This study aimed to analyze the N-glycome of milk whey glycoproteins from various milk sources using a linkage-specific ethyl esterification approach with MALDI-MS (matrix-assisted laser desorption/ionization-mass spectrometry). The results showed that the N-glycan profiles of bovine and buffalo whey mostly overlapped. Acetylated N-glycans were only detected in donkey milk whey at a rate of 16.06%. a2,6-linked N-Acetylneuraminic acid (a2,6-linked NeuAc, E) was found to be the predominant sialylation type in human milk whey (65.16%). The amount of a2,6-linked NeuAc in bovine, buffalo, goat, and donkey whey glycoproteomes was 42.33%, 44.16%, 39.00%, and 34.86%, respectively. The relative abundances of a2,6-linked N-Glycolylneuraminic acid (a2,6-linked NeuGc, Ge) in bovine, buffalo, goat, and donkey whey were 7.52%, 5.41%, 28.24%, and 17.31%, respectively. Goat whey exhibited the highest amount of a2,3-linked N-Glycolylneuraminic acid (a2,3-linked NeuGc, Gl, 8.62%), while bovine and donkey whey contained only 2.14% and 1.11%, respectively.

RESUMEN

Anatomic syndesmosis reduction is necessary to restore ankle biomechanics and prevent poor clinical outcomes, but malreduction can be encountered frequently since the ideal fixation angle varies between patients and fixation levels. This study aimed to validate the angle bisector method to reveal whether it provides an accurate syndesmotic fixation angle that is patient- and level-specific. Lower extremity CT angiography of 50 consecutive patients (25 male, 25 female) without evident ankle pathology were evaluated. The average age was 52.8 (±18, range: 18-75). Lines tangent to anterior and posterior cortices of tibia and fibula were drawn in the axial plane at both 2 cm and 3.5 cm above the ankle joint line. Bisection of the angle formed between these lines was drawn and its relationship with the centroidal axis, which is proposed to be the ideal syndesmotic axis, was evaluated. The angle between the bisector line & the centroidal axis and the distance between their most lateral intersections with the fibula were calculated. The measurements were made by 3 blinded observers. Intra- and interobserver reliability analyses were conducted. The average centroidal axis-bisector angle was 2.1° ± 2.1° at 2 cm and 0.6° ± 1.3° at 3.5 cm level. The average distance to the actual syndesmosis entry point was 1.0 ± 0.9 mm at 2 cm and 0.4 ± 0.4 mm at 3.5 cm level. The values didn't show any significant difference according to gender. Intra- and interobserver reliability analysis showed excellent correlation in all parameters (interclass correlation coefficient > 0.90). Angle bisector method was found strongly reliable providing accurate direction for syndesmotic axis. It can provide a patient- and level-specific angle for the application of syndesmotic implants without increasing the fluoroscopy exposure. Its use can have a broad impact on functional outcomes of ankle injuries by decreasing the malreduction rates. Further cadaveric validation and safety studies should be conducted for possible clinical usage.

RESUMEN

OBJECTIVE: Although the etiopathogenesis of preeclampsia (PE) is unknown, evidence suggests that it may be associated with increased oxidative stress. Studies have shown that oxidative stress can affect DNA fragments called telomeres. However, the interactions of PE, oxidative stress, and telomere length are not clearly known. This study aims to evaluate the oxidative/anti-oxidative stress balance in the placenta and umbilical cord and examine the effect of oxidative stress on telomeres. MATERIALS-METHOD: Cord blood and placental samples were collected from 27 pregnant women with severe PE (280/7-336/7 gestational weeks) and 53 healthy pregnant women. Telomere length (TL) was measured by real-time PCR in the cord blood and placenta tissue. Total antioxidant status (TAS) and total oxidant status (TOS) levels were measured in the cord blood and placenta tissue using a colorimetric method. RESULTS: No significant differences were found between groups regarding age, BMI, gravida, parity, and newborn gender (p>0.05). Cord blood and placental TL of PE patients were significantly shorter than the control group, while cord blood and placental TAS and TOS levels were higher (p<0.05). The results of a multivariate logistic regression analysis showed that the level of placental TOS in PE patients (OR=1.212, 95% CI=1.068-1.375) was an independent risk factor affecting PE. CONCLUSION: This study found that oxidative stress is an independent risk factor in the development of PE and shortens TL in both placental and umbilical cord blood. Future research on telomere homeostasis may offer a new perspective for the treatment of PE.

RESUMEN

Treatment of genetic disorders by genomic manipulation has been the unreachable goal of researchers for many decades. Although our understanding of the genetic basis of genetic diseases has advanced tremendously in the last few decades, the tools developed for genomic editing were not efficient and practical for their use in the clinical setting until now. The recent advancements in the research of Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) and CRISPR-associated protein (Cas) systems offered an easy and efficient way to edit the genome and accelerated the research on their potential use in the treatment of genetic disorders. In this review, we summarize the clinical trials that evaluate the CRISPR/Cas systems for treating different genetic diseases and highlight promising preclinical research on CRISPR/Cas mediated treatment of a great diversity of genetic disorders. Ultimately, we discuss the future of CRISPR/Cas mediated genome editing in genetic diseases.

RESUMEN

Aim: The research was carried out to determine the attitudes of nursing undergraduate students toward e-learning implemented during the COVID-19 pandemic. Subject and methods: The study sample consisted of 320 undergraduate students studying at the Faculty of Health Sciences, Nursing Department of a state university. Personal Information Form and the Test of e-Learning Related Attitudes were administered to the research participants. Results: Of the students, 68.8% were female and 51.6% were between the ages of 21-24. The attitude of 55.3% (177) toward e-learning is negative. Attitude scores of students aged 25-29 were significantly higher compared to those aged 17-20 and 21-24 years old (p = 0.002). The attitude scores of the students who have a computer are significantly higher than those who do not (p = 0.001). Most students did not agree with the statement "E-learning will provide me with better learning opportunities than conventional learning methods." (disagree n = 121; 37.8%, strongly disagree n = 110; 34.4%). Conclusion: It is noticed that e-learning is not sufficient in subjects such as conducting clinical and laboratory practices in health sciences fields with practical training like nursing, and students' attitudes are generally negative. For undergraduate health sciences education, face-to-face and online education for support purposes can be used together in theoretical courses. In addition, it is recommended to use effective online communication techniques in online courses.

RESUMEN

BACKGROUND: The retinol level and retinol delivery to the placenta may vary depending on various factors involving the mother and newborn. The present study evaluates the factors affecting retinol levels in newborns and the transplacental retinol passage in preterm newborns. METHODS: In this prospective cohort study, the retinol and retinol binding protein (RBP) in the umbilical cord blood of 44 preterm infants with a gestation age of <30 weeks were studied. Serum retinol and RBP levels were determined using an enzyme-linked immunosorbent assay, and the rate of transplacental retinol passage was calculated. The demographic data of mothers and newborns, the use of vitamins by the mother, the application of antenatal corticosteroids, and any diseases diagnosed during pregnancy were recorded. An evaluation was made of the retinol, RBP, and other factors of the mother and newborn affecting transplacental retinol passage. RESULTS: A retinol deficiency was identified in 68.2% of the study population. Retinol and RBP levels in umbilical cord blood (273.7 ± 150.03 ng/mL, 7.88 ± 5.6 ng/mL, respectively) were significantly higher than the corresponding levels in the mother (206.4 ± 86.26 ng/ mL, 1.04 ± 0.97 ng/mL, respectively). Umbilical cord blood retinol deficiency was more common in the male participants, while the transplacental retinol passage rate was higher in females. The umbilical cord blood RBP was found to be lower in those administered antenatal corticosteroids than in those who did not receive antenatal corticosteroids, and median maternal RBP levels were lower in patients with anemia and pregnancy-induced hypertension than in those with no disease. DISCUSSION: Placental adaptation and contributing factors may vary in populations with severe retinol deficiency. The finding of significantly increased cord blood retinol levels when compared to maternal retinol levels in the present study suggests that some compensatory mechanisms, such as increased placental RBP levels, support the presentation of retinol to the fetus, even if the mother has a retinol deficiency.

Personal Data Form, Stress Coping Scale, State and Trait Anxiety Scale were sent online to students' smartphones and/or e-mails as data collection tools and it was collected this way.The mean age of the participants was 21.09 ±â€Š2.02 (years). 78% of respondents were women. 48.4% of the participants were students of Çukurova University. It was determined that 201 (69.1%) of the participants isolated themselves during the pandemic. It was found that 171 students (58.8%) spent 23 to 24 hours at home, whereas 284 students (97.6%) spent time with their parents/siblings. 47.4% of respondents stated that they had spent the pandemic watching a series/film. 47.1% of respondents had good family relationships. 50.2% of respondents had good relationships with college friends. 74.9% of respondents said they were happy. Women's trait anxiety scale scores were higher than men's (P < .05). Men have higher problem-Oriented coping scores than women (P < .05). Significant differences were found in the Status Anxiety Scale scores and trait anxiety scale scores according to self-isolation status (P < .05). A significant difference was found in terms of state anxiety scale and trait anxiety scale according to happiness status (P < .05). The problem-based coping scores of those who were happy with the Stress Coping Scale were higher than those who were not happy (P < .05). The state anxiety scale of the students was 42.54, and the trait anxiety scale was 45.16.Nursing students' status and sustained Anxiety Scale scores were moderate. It is important for individuals to have good family and friends and to be happy in the process of the Corona Virus Disease pandemic.

RESUMEN

BACKGROUND: The bibliometric studies in the field of orthopaedics have gained popularity since they can determine the characteristics and research trends of most influential papers in specific subjects. This study aimed to evaluate the 50 most-cited articles related to hallux rigidus, and analyze possible factors associated with increased citation counts. METHODS: The available literature about hallux rigidus on Web of Science database until January 2021 were analyzed and the 50 most-cited articles were determined. The characteristics of the papers were documented and analyzed for any relationship or correlation with total citation or citation per year (citation density) values. RESULTS: The average citation number and citation density were 52.8 (range: 26-243) and 3 (range: 0.8-12.8), respectively. The average author number was 3.4, while the average institution number was 1.9. The USA had the highest number of articles with 29. Twenty-six papers were case-series, only 3 studies had level 1 and only 2 had level 2 evidence. The highest number of articles were published in Foot and Ankle International with 22 papers. Forty papers were clinical studies while 10 were reviews. Five studies were multicentric. CONCLUSION: This study provided the general characteristic and research trends of 50 most influential hallux rigidus papers. The number of institutions and references were positively correlated with citation density, indicating a higher chance of getting cited for papers with collaborations from different institutions and papers using more references from other works. Publication year was also positively correlated with citation density, indicating the better performance of more recent articles. LEVEL OF CLINICAL EVIDENCE: Level 3.

RESUMEN

Objective: This study aimed to define the rare Brucella infection in pregnancy and its effects on immunoglobulins (Ig). Materials and Methods: This prospective study has conducted Brucella screening using the Rose Bengal test on pregnant and non-pregnant outpatients who did not show any specific Brucella symptoms. The immunoglobulin levels were measured using the enzyme-linked immunosorbent assay. The study group consisted of pregnant women who were at 20 weeks or below gestation and applied to our hospital outpatient clinic for routine check-ups. The control group consisted of healthy patients who applied for routine controls. Results: This study included a total of 584 participants, 293 of whom were controls and 291 were the study (pregnant) participants. The study revealed a 1.5% incidence of Brucella during pregnancy. In acute and chronic Brucella infection, lower levels of IgA response were observed in pregnant cases compared to the control group. Conclusion: Brucella infection is a disease that can cause fetal problems, especially in endemic areas. The role of the altered IgA response in pathologies that are associated with Brucella infection stands out as a new target for disease pathophysiology.

RESUMEN

BACKGROUND AND PURPOSE: The aim of this study was to investigate the knowledge level of nurses and midwives about the level of knowledge about neonatal resuscitation and the effect of education on knowledge levels. METHODS: The research was applied in January 2016 to the nurses and midwives who worked in neonatal intensive care units, gynecology and maternity wards at Cukurova University Balcali Hospital, Adana Numune Training and Research Hospital, Adana Maternity and Children Diseases Hospital, and had received Neonatal Resuscitation Program practitioner training course. All of the target populations were included in the research before the sample was determined. Data were collected using a questionnaire form consisting of 40 questions including sociodemographic information and knowledge level related to NRP. RESULTS: It was determined that the nurses and midwives answered the questions correctly related to oxygen usage (98.1%) and all the things that should be conducted in order to prevent heat loss in baby (98.1%). It was determined that NRP knowledge points of nurse/midwives were intermediate level as 23.06 ± 3.47 (min: 12; max: 30) and most of the participants (37%) had got NRP course in the last 4-5 years. There was a statistically significant difference between participating time to NRP practitioner training course and working years (p < 0.05). IMPLICATIONS FOR PRACTICE: Systematic repetition of knowledge and skills through in-service training programs is important, as it will lead to a reduction of mortalities of newborns. IMPLICATIONS FOR RESEARCH: It was observed that the knowledge points were quite good considering that the participants of the NRP practitioner-training course had taken the course in the last 4-5 years.

RESUMEN

The aim of this study is to assess the FNDC5 and myonectin expressions and serum levels of myonectin and irisin in women with PCOS. 90 participants were included in this case-control study. 45 of these participants were with PCOS, and 45 of them were healthy volunteers matched for age and body mass index (BMI). Serum irisin and myonectin levels were measured with commercially available enzyme-linked immune sorbent assay (ELISA) kits. Expression of the myonectin and FNDC5 genes were determined by RT-PCR analysis. It was found out that FSI, HOMA-IR, LH, LH/FSH, TT, serum irisin and serum myonectin levels, myonectin mRNA expression, and FNDC5 mRNA expression were higher in the PCOS group, whereas HDL-C level was lower in the PCOS group (p < .05). When the groups were compared, it was detected that IR and HA were significantly higher in the PCOS group (p < .05). Serum irisin and myonectin levels, and myonectin and FNDC5 mRNA expressions were increased in women with PCOS. These molecules can be target molecules in PCOS pathophysiology and treatment.IMPACT STATEMENTWhat is already known on this subject? Although the aetiology of PCOS is not fully understood, it is thought that insulin resistance may play a critical role. In recent studies, the relationship of cytokines secreted from skeletal muscle with insulin resistance has been shown. The effects of irisin and myonectin, which are members of the myokine family, on lipid and glucose metabolism are known.What do the results of this study add? Although there are many studies in the literature regarding serum irisin levels in women with PCOS, their results are confusing. There is a study in the literature investigating the relationship between myonectin and PCOS. In our study, we evaluated myonectin and FNDC mRNA expressions in addition to serum irisin and myonectin levels. As a result, we found that markers and their mRNA expressions were lower in patients with PCOS compared to controls.What are the implications of these findings for clinical practice and/or further research? We think that the results of our study will shed light on future studies. Due to their effects on adipose tissue, these markers may play a role in the aetiology of long-term complications of PCOS. Moreover, they can become pharmacological targets in preventing these complications.

RESUMEN

Objective This study was planned to evaluate obstetricians' practices of umbilical cord clamping, milking, and skin-to-skin contact applications and to determine the related variables. Material and methods A total of 522 obstetricians participated in the study. Participants were reached via the internet and a 15-item questionnaire was applied about umbilical cord clamping, cord milking, and skin-to-skin contact. Mann-Whitney U test and Student's t-test were used for continuous data and Chi-square test or Fisher's exact test for categorical data in determining the difference between groups. For the multivariate analysis, the possible factors identified with univariate analyses were entered into the logistic regression analysis to determine further independent predictors of delayed clamping. Statistical analysis was performed using the SPSS software (version 20, IBM Corp, Armonk, USA). Results It was determined that 234 (44.8%) of the participants clamped the umbilical cord early whereas 288 (55.2%) clamped it late. It was found that the delayed clamping rates of physicians working in public hospitals were significantly lower than those working in private (p<0.001). It was observed that 132 of the participants (25.3%) did not milk the cord and 180 (34.5%) of them applied it continuously, and no significant difference was found between physicians working in the public and private sectors (p=0.130). It was observed that 384 (73.6%) physicians applied skin-to-skin contact. In the multivariate regression analysis, it was determined that working status in a private hospital with a 3.6 odds ratio (OR) (95% CI = 2.0-6.3) and a low number of patients examined daily with a 1.2 OR (95%CI= 1.0-1.4) were the most important independent factors affecting the choice of delayed clamping. Conclusion It is seen that the most important parameter affecting the birth practices of physicians in our country is the employment status in public or private institutions. The age and professional experience of the physicians who clamp the umbilical cord late were found to be higher. Obstetricians are at the key point in obstetrics practice, and the experience of physicians and the type of institution they work with affect these practices.

RESUMEN

BACKGROUND: Necrotizing enterocolitis (NEC) is one of the most important causes of morbidity and mortality in premature infants. Although there are no specific diagnostic tools, the main factors affecting prognosis are clinical and laboratory findings, and early diagnosis and treatment. In this study, we demonstrate the importance of dual-energy computed tomography (DECT) in confirming intestinal ischemia in neonates with NEC. METHODS: Patients diagnosed with NEC in a neonatal intensive care unit were staged according to modified Bell's classification, and DECT was performed on patients with NEC stages 2-A, 2-B and 3-A. According to their DECT reports, these patients were then separated into two groups: those with intestinal ischemia and those without intestinal ischemia. The patients with intestinal ischemia were evaluated using surgical reports, and the other patients were evaluated using clinical findings. RESULTS: DECT was performed in 21 patients with NEC stages 2-A, 2-B and 3-A. Twelve patients (57.1%) without ischemia were followed up without surgery. Nine patients (42.9%) with ischemia on DECT were operated on, and resection and anastomosis or ileostomy and colostomy were performed. DISCUSSION: In patients with NEC, DECT significantly increases overall diagnostic confidence in assessing intestinal necrosis when compared with traditional diagnostic methods.

RESUMEN

BACKGROUND: In this study, we evaluated to the relationship between the type of accessory navicular bone (ANB) and radiological parameters of foot in patients with bilateral ANB of different types. METHODS: Patients with bilateral ANB of different types participated in this study, from May 2019 to April 2020. Patient data, including age, sex, body mass index (BMI), and presence of symptoms were obtained. We aimed to compare the radiological parameters of both the feet for evaluate the differences from one another in patients with bilateral ANB of different types (one side type 1 and contralateral side type 2) because the foot angles may differ in each person. Seven radiographic parameters were measured, including calcaneal pitch angle, talocalcaneal angle, tibiocalcaneal angle, naviculocuboid overlap, talonavicular coverage angle, anteroposterior talo-first metatarsal angle, and the lateral talo-first metatarsal angle, which evaluated hindfoot, midfoot, and forefoot alignment. RESULTS: Twenty patients (13 women and 7 men) with a mean age (and standard deviation) of 38.5 {plus minus} 12.3 years were included in the study. The patients had a mean height of 168.1 {plus minus} 7.1 cm, a mean weight of 77.2 {plus minus} 10.5 kg, and a mean BMI of 27.4 {plus minus} 4.3 kg/m2. There was no significant difference between type 1 and type 2 in all radiological parameters. There was no significant correlation between radiological parameters and age, BMI, or the presence of symptoms. CONCLUSIONS: We found that the type of ANB had no effect on the radiological measurements of the foot in which we evaluate the parameters patients with bilateral ANB of different types. Additionally, age, BMI, and the presence of symptoms, also demonstrated no correlation with the radiological parameters of the foot.

RESUMEN

AIM: Ovarian torsion is a gynecopathology that requires emergency surgery in women. However, ischemia reperfusion injury (IRI) occurs after treatment with detorsion. This study aimed to evaluate the effects of monoacylglycerol lipase inhibitor JZL184 on ovarian IRI and ovarian reserve. METHODS: Forty-eight female Wistar albino rats were divided into six groups. Group 1: Sham, Group 2: Ischemia, Group 3: ischemia/reperfusion (IR), Group 4: IR + JZL184 4 mg/kg, Group 5: IR + JZL184 16 mg/kg, Group 6: IR + vehicle (dimethyl sulfoxide). Three hours of ischemia followed by 3 h of reperfusion. Two different doses of JZL184 (4 and 16 mg/kg) were administered intraperitoneally in Group 4 and 5, 30 min before reperfusion. Ovarian IRI and ovarian reserve were evaluated in serum and tissue by using histopathological and biochemical parameters. RESULTS: Treatment with JZL184 was associated with a significant increase in ovarian 2-arachidonoylglycerol and improved serum anti-Mullerian hormone, Inhibin B, primordial follicle count, and ovarian histopathological damage score (p < 0.05). JZL184 treatment significantly decreased the level of malondialdehyde, and increased superoxide dismutase enzyme activity and glutathione (GSH) levels (p < 0.05). The increased phosphorile nuclear factor-κB (Phospho-NF-κB-p65), tumor necrosis factor alpha (TNF-α), interleukin-1beta (IL-1ß), transforming growth factor beta 1 (TGF-ß1), and TUNEL assay immunopositivity scores in ovarian I/R injury were decreased after treatment with JZL184 (p < 0.05). CONCLUSIONS: JZL184 showed significant ameliorative effects on ovarian IRI and ovarian reserve caused by IR through acting as an antioxidant, anti-inflammatory, and antiapoptotic agent. Thus, JZL184 may be a novel therapeutic agent for ovarian IRI.

RESUMEN

We investigated the efficacy of activated cannabinoid 2 receptors for alleviating ovarian ischemia-reperfusion injury in rats. Female Wistar albino rats were divided randomly into six groups: ischemia-reperfusion (IRG); ischemia-reperfusion + 0.2 mg/kg JWH-133 (JIRG1), ischemia-reperfusion + 1 mg/kg JWH-133 (JIRG2); ischemia-reperfusion + 5 mg/kg JWH-133 (JIRG3); solvent control, and sham control. Ovarian ischemia was established for 3 h followed by reperfusion for 3 h. Ovarian tissue was investigated using histology, immunohistochemistry and biochemistry. Administration of JWH-133 synthetic cannabinoid reduced nuclear factor kappa-B immunoreactivity as well as TUNEL positivity scores and malondialdehyde levels. These reductions were significant in all cases except for the malondialdehyde levels in the 1 mg/kg JWH-133 group. Activation of cannabinoid 2 receptors by JWH-133 reduced ovarian ischemia-reperfusion injury due to its antioxidant and anti-inflammatory effects.
