RESUMEN
Background: The coronary angiography results in a group of patients with myocardial infarction (MI) are normal or near-normal; which is diagnosed as myocardial infarction with non-obstructive coronary arteries (MINOCA). This study aimed to compare the mortality rate and risk factors between MINOCA and myocardial infarction with obstructive coronary artery (MI-CAD). Methods: This retrospective cohort study was conducted from January 1, 2018, to December 31, 2019. A total of 679 patients admitted to Afshar Hospital in Yazd with a diagnosis of ST-elevation myocardial infarction (STEMI) from 2018-2019 who underwent primary Percutaneous Coronary Intervention (PCI) were enrolled in the study. Demographic, and clinical variables, ECG finding and one-year mortality, were extracted using MI registry data from the Yazd Cardiac Research Center. Results: The estimated frequency of MINOCA was 4.6%. Patients with MINOCA (47.14±6.2) were younger than patients with MI-CAD (57.61±9.1) (P <0.0001). MINOCA patients (47.4±9.47) had a considerably greater left ventricular ejection fraction (LVEF) than MI-CAD patients (43.5±6.8) (P =0.018). The majority site of MI in MINOCA patients was located in the non-anterior wall (p <0.0001). A comparison of MINOCA and MI-CAD patients' one-year mortality revealed no significant difference (P =0.07). Conclusion: The prevalence of patients with MINOCA in Yazd was similar to other communities. Although these patients probably do not have a better prognosis, despite being younger and having better LV systolic function and lower CAD risk factors.
RESUMEN
BACKGROUND: We decided to investigate the antileishmanial, cellular mechanisms, and cytotoxic effects of green synthesized Zinc nanoparticles (ZnNPs) alone and combined with glucantime against Leishmania major infection. METHODS: The effect of green synthesized ZnNP on L. major amastigote was studied through macrophage cells. The mRNA expression level of iNOS and IFN-γ followed by the exposure of J774-A1 macrophage cells to ZnNPs was assessed by Real-time PCR. The Caspase-3-like activity of promastigotes exposed to ZnNPs was studied. Effects of ZnNPs alone and combined with glucantime (MA) were studied on cutaneous leishmaniasis in BALB/c mice. RESULTS: ZnNPs displayed the spherical shape with sizes ranging from 30 to 80 nm. The obtained IC50 values for ZnNPs, MA, and ZnNPs + MA were 43.2, 26.3, and 12.6 µg/mL, respectively; indicating the synergistic effects of ZnNPs in combination with MA. CL lesions had completely improved in the mice received with ZnNPs in combination with MA. The mRNA expression level of iNOS, TNF-α, and IFN-γ was dose-dependently (p < 0.01) upregulated; whereas it was downregulated in IL-10. ZnNPs markedly stimulated the caspase-3 activation with no significant toxicity on normal cells. CONCLUSION: Based on these in vitro and in vivo results, green synthesized ZnNPs, mainly along with MA, showed that has the potential to be introduced as a new drug for CL therapy. Triggering of NO production, and inhibition of infectivity rate are revealed as mechanisms of action ZnNPs on L. major. But, supplementary investigations are necessary to clear the efficacy and safety of these agents.

Aluminum phosphide (AlP) is widely used for protecting grains from pests. AlP releases toxic phosphine gas (PH3) while exposed to humidity. Poisoning with these tablets is dangerous and can cause death or serious injuries. Up to now, no definite antidote has been introduced for specific treatment of this poisoning. Sevelamer carbonate or sevelamer hydrochloride (Renagel) is a polymeric pharmaceutical prescribed for treating hyperphosphatemia in patients with chronic kidney disease. Sevelamer can bind with phosphate groups and act as an anion exchanger. Herein, sevelamer is repurposed as a potent antidote agent in phosphine gas poisoning. In vivo evaluation was conducted on male Sprague Dawley rats. The evaluation was conducted on three groups of animals: control, AlP-poisoned, and AlP-poisoned treated with sevelamer. Survival percentage, serum biomarkers level of organ injury, and ATP level were recorded. The results indicate a high survival rate in sevelamer-treated animals compared with the AlP-poisoned group (75% vs. 0% respectively, 48 h after poisoning). The analysis of serum markers of organ injury also showed that sevelamer could reduce toxicity and organ injury in poisoned animals. ATP level of separate organs showed that sevelamer treated groups were recovered. The results showed that sevelamer could be a potent antidote for managing aluminum phosphide poisoning. Moreover, a mechanism is suggested for the interaction of sevelamer with phosphine gas.
RESUMEN
Background and Aims: Acute appendicitis is one of the most common causes of lower abdominal pain, which is considered a general surgical emergency worldwide. The present study aimed to compare the diagnostic value of Raja Isteri Pengiran Anak Saleha Appendicitis (RIPASA) and Alvarado score systems in diagnosing acute appendicitis. Methods: A prospective cross-sectional study was conducted at Shahid Sadoughi and Shahid Rahnemoon Hospitals in Yazd between September 2020 and February 2020. The statistical population consisted of all of the patients referred to the Accident and Emergency department with right iliac fossa (RIF) pain. All patients were scored using Alvarado and RIPASA scoring system. sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were computed by using SPSS statistical software. An receiver operating characteristic curve were plotted. Results: In present study, one hundred suspected patients with appendicitis who underwent appendectomy were evaluated. The mean age of our study population was 25.2 ± 12.1 years, and the gender distribution was 57% males and 43% females. The sensitivity, specificity, PPV and NPV of RIPASA were 86.6%, 66.7%, 92.2%, and 52.2%, respectively. The sensitivity, specificity, PPV and NPV of Alvarado score were 67.1%, 72.2%, 91.7%, 32.5%, respectively. The diagnostic accuracy was 68% for Alvarado score and 83% for RIPASA. The area under the curve for RIPASA (0.87) was more than that for Alvarado score (0.77). Conclusion: The RIPASA score system had higher sensitivity, PPV, NPV, and accuracy than the Alvarado one. It is recommended for the physician and surgeon to evaluate patients with RIF pain using the RIPASA score.
RESUMEN
BACKGROUND: Ifosfamide (IFO) is an alkylating agent administered against different types of malignancies. Several cases of renal injury and serum electrolytes disturbances have been reported in IFO-treated patients. Oxidative stress and mitochondrial dysfunction are suspected of being involved in the mechanism of IFO nephrotoxicity. Carnosine is a dipeptide which its antioxidant and mitochondria protecting properties have been mentioned in different experimental models. The current study aimed to evaluate the nephroprotective properties of carnosine against IFO-induced renal injury. METHODS: Rats were treated with IFO (50 mg/kg, i.p) alone or in combination with carnosine. Serum and urine biomarkers of renal injury in addition to kidney markers of oxidative stress were evaluated. Moreover, kidney mitochondria were isolated, and some mitochondrial indices were assessed. RESULTS: Elevated serum creatinine and BUN, hypokalemia, and hypophosphatemia, in addition, to an increase in urine glucose, protein, γ-GT, and alkaline phosphatase (ALP), were evident in IFO-treated animals. IFO also caused an increase in kidney reactive oxygen species (ROS) and lipid peroxidation (LPO). Renal GSH levels and antioxidant capacity were also depleted with IFO therapy. Mitochondrial dehydrogenase activity, GSH level, membrane potential, and ATP content were decreased while mitochondrial LPO and permeabilization were increased in IFO group. Carnosine (250 and 500 mg/kg, i.p) mitigated IFO-induced oxidative stress and mitochondrial impairment in renal tissue. CONCLUSION: Our data suggest mitochondrial dysfunction and oxidative stress as fundamental mechanisms of renal injury induced by IFO. On the other hand, carnosine supplementation protected kidneys against IFO-induced injury through regulating mitochondrial function and mitigating oxidative stress.

Cholestasis is a significant decrease in bile flow. The liver is the primary organ affected by cholestasis. Chronic cholestasis could entail to tissue fibrotic changes and liver cirrhosis. Other organs, including heart, kidneys, nervous system, skeletal muscles, as well as the reproductive system, might also be affected during cholestasis. Although the cholestasis-associated pathological and biochemical alterations in organs such as liver have been widely investigated, there is little information about complications such as cholestasis-induced reproductive toxicity. The current study aimed to evaluate the pathologic effects of cholestasis on reproductive organs in both male and female animals. Rats underwent bile duct ligation (BDL) surgery. Markers of reproductive toxicity, including serum hormonal changes, tissue histopathological alterations, biomarkers of oxidative stress, and markers of mitochondrial impairment, were evaluated. Increased serum markers of liver injury and elevated level of cytotoxic molecules such as bile acids and bilirubin were evident in BDL animals. On the other hand, the serum level of hormones such as testosterone was suppressed in BDL rats. Significant histopathological alterations were also evident in the testis and ovary of BDL animals. A significant increase in oxidative stress markers, including ROS formation, lipid peroxidation, protein carbonylation, and depleted glutathione and antioxidant reservoirs were also detected in BDL rats. Moreover, mitochondrial depolarization decreased dehydrogenases activity, and depleted ATP content was detected in sperm isolated from the BDL group. These data indicate that cholestasis-associated reproductive toxicity in male and female rats is restrictedly coupled with severe oxidative stress and mitochondrial impairment.

Imatinib is a tyrosine kinase inhibitor widely administered against chronic myeloid leukemia. On the other hand, drug-induced kidney proximal tubular injury, electrolytes disturbances, and renal failure is a clinical complication associated with imatinib therapy. There is no precise cellular mechanism(s) for imatinib-induced renal injury. The current investigation aimed to evaluate the role of mitochondrial dysfunction and oxidative stress in the pathogenesis of imatinib nephrotoxicity. Rats received imatinib (50 and 100 mg/kg, oral, 14 consecutive days). Serum and urine biomarkers of renal injury and markers of oxidative stress in the kidney tissue were assessed. Moreover, kidney mitochondria were isolated, and mitochondrial indices, including mitochondrial depolarization, dehydrogenases activity, mitochondrial permeabilization, lipid peroxidation (LPO), mitochondrial glutathione levels, and ATP content were determined. A significant increase in serum (Creatinine; Cr and blood urea nitrogen; BUN) and urine (Glucose, protein, gamma-glutamyl transferase; γ-GT, and alkaline phosphatase; ALP) biomarkers of renal injury, as well as serum electrolytes disturbances (hypokalemia and hypophosphatemia), were evident in imatinib-treated animals. On the other hand, imatinib (100 mg/kg) caused an increase in kidney ROS and LPO. Renal tubular interstitial nephritis, tissue necrosis, and atrophy were evident as tissue histopathological changes in imatinib-treated rats. Mitochondrial parameters were also adversely affected by imatinib administration. These data represent mitochondrial impairment, renal tissue energy crisis, and oxidative stress as possible mechanisms involved in the pathogenesis of imatinib-induced renal injury and serum electrolytes disturbances.
RESUMEN
BACKGROUND: Cyclophosphamide (CP), as a chemotherapy drug, causes severe damage in testicular tissue through producing free radicals. Cerium oxide nanoparticles (NC) exhibit antioxidant and anti-inflammatory properties. The purpose of this study was to investigate the protective effect of NC on CP-induced testicular damage in mice. METHODS: In this experimental study, thirty-two male mice were divided into four groups (eight mice in each group). The control group was received intraperitoneally (IP) normal saline, NC group was received NC for three consecutive days (100 µg/kg, IP), CP group was received CP (200 mg/kg, IP), and the CP + NC group received NC, three consecutive days before receiving CP. After 2 days, testicles were assessed for biochemical, histomorphometrical, histopathological, and immunohistochemical analyses. RESULTS: CP administration caused statistically significant increases in sperm abnormality, malondialdehyde, protein carbonyl levels, reactive oxygen species, level and apoptosis, and decreases in sperm count, sperm viability, testosterone, glutathione activity, the mean thickness of the germinal epithelium, diameter of seminiferous tubules in mice. Degeneration, necrosis, arrest of spermatogenesis, congestion, and atrophy in testicular tissue confirmed the low Johnsen's Testicular score in CP group. Administration of NC significantly ameliorated the CP-induced adverse effects on testis compared with the CP group. In addition, pretreatment mice with NC significantly reduced caspase-3 immunoreactivity induced by CP in testis. CONCLUSIONS: This study showed that NC with scavenging free radicals and antiapoptotic properties enable to reduce the side effects of CP in the testicular tissue.
RESUMEN
Cyclophosphamide (CP), as a chemotherapy drug, induces hepatotoxicity through causing oxidative stress. Atorvastatin (ATV) at a low dose has antioxidant and anti-inflammatory properties. The present study was designed to investigate the protective effects of ATV against CP-induced hepatotoxicity in rat. In this experimental study, 32 rats were treated with ATV orally at a dose of 10 mg/kg for 10 consecutive days, 5 days before and 5 days after the administration of a single intraperitoneal injection of CP (150 mg/kg). The hepatoprotective effect of ATV was evaluated by measuring liver function markers, oxidative markers, histological and immunohistochemical assays. The biochemical results showed that administration of CP increased hepatic biomarkers enzymes as aspartate aminotransferase (AST), alanine aminotransferase (ALT) and lactate dehydrogenase (LDH) levels. CP increased malondialdehyde (MDA), protein carbonyl (PC) and decreased glutathione (GSH) content in rats. Moreover, administration of CP was associated with periportal leucocyte infiltration, dilation sinusoids, hepatocyte vacuolation, congestion and hemorrhage in livers of rats. CP significantly increased immunoreactivity of caspase-3 as a marker of apoptosis in liver tissue. ATV markedly mitigated liver injury through reduction in oxidative stress biomarkers, histopathological findings and apoptosis. The antioxidant and anti-apoptotic activities of ATV are main proposed mechanisms involved in its hepatoprotective effects against CP-induced hepatic injury.
RESUMEN
BACKGROUND: Cyclophosphamide (CP), as an anticancer agent, causes ovarian toxicity and subsequent infertility in women. Atorvastatin (ATV) at a low dose has antioxidant and anti-inflammatory properties. OBJECTIVE: The aim of this study was to investigate the protective effect of ATV against CP-induced ovarian injury in rat. MATERIALS AND METHODS: In this experimental study, thirty-two female Wistar rats were randomly divided into four groups as I) control, II) ATV (10 mg/kg), III) CP (150 mg/kg), and IV) CP +ATV. The ATV treated groups were received ATV for 10 days via oral gavage. In the CP+ATV group, ATV was administrated on 5 days before and 5 days after CP injection. Histological structure, apoptosis (caspase-3), oxidative stress parameters as malondialdehyde, reactive oxygen species, protein carbonyl levels and cell viability were evaluated in ovary tissue by histological scores, immunohistochemistry, histochemical and biochemical assays. The levels of estrogen and progesterone hormones were measured on the 12th day of study. RESULTS: ATV pretreatment significantly decreased the levels of oxidative stress biomarkers as malondialdehyde, reactive oxygen species and protein carbonyl levels and increased cell death in CP-treated rats as compared with the CP alone group. ATV significantly increased estrogen and progesterone levels in CP-treated rats. In addition, the histological examination showed ATV mitigated acute inflammation, degenerative cells in stroma and follicles, stromal edema, vacuolization, atresia of the follicles and congestion of blood vessels in the CP-treated animals. Furthermore, ATV significantly reduced immunoreactivity level of caspase-3 in CP-treated rats. CONCLUSION: Our results showed that the ATV with antioxidant and anti-apoptosis (caspase-3) activities protected ovarian against CP-induced toxicity.
RESUMEN
OBJECTIVES: Cisplatin (CP), as an anti-neoplastic drug, causes testicular damage. Zataria multiflora Boiss (ZM), a medicinal plant, has antioxidant and anti-inflammatory properties. The aim of this study was to investigate the effects of ZM against CP-induced testicular toxicity. MATERIALS AND METHODS: In this experimental study, thirty-two adult male mice were randomly divided into four groups. The control group received normal saline with oral gavage during 7 days; ZM group received ZM (200 mg/kg) during 7 days by gavage; CP group received CP (10 mg/kg) intraperitoneally (IP) in the 5th day of study; ZM + CP group received ZM during 7 days and CP was injected in 5th day. Sperm parameters, biochemical (MDA, GSH, and PC) levels, serum testosterone levels, and histopathological and immunohistochemical assays of testis were examined one day after the last drug treatment. RESULTS: CP treatment caused significant damage via changed sperm parameters (sperm motility, count, viability rate, and abnormalities), increased oxidative stress (increased MDA and PC levels, and decreased GSH level), histological changes (degeneration, necrosis, arrest of spermatogenesis, congestion, and decrease in thickness of the germinal epithelium, diameter of seminiferous tubules, and Johnsen's Score), decreased serum testosterone level, and increased caspase-3 immunoreactivity. ZM preserved spermatogenesis and mitigated the toxic effects of CP on the testis tissue. In addition, treatment with ZM significantly reduced caspase-3 immunoreactivity. CONCLUSION: The findings of this study suggest that ZM as a potential antioxidant compound and due to free radicals scavenging activities has a protective effect against CP-induced testicular toxicity.
RESUMEN
BACKGROUND: Previous studies have indicated that exercise training improves body composition and cardiovascular disease risk factors. The aim of the present study was to investigate the effect of 12 weeks of aerobic, strength and combined training on body composition, intercellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), and C-reactive protein (CRP) in sedentary middle-aged men. METHODS: Forty-seven male aged 40-60 years voluntarily participated in this study and were divided in four groups: aerobic (n = 12), strength (n = 12), combined (n = 11), and control (n = 12) groups randomly. Body composition, ICAM-1, VCAM-1, and CRP were measured before and after 12 weeks. Data were analyzed using paired t-test and analysis of variance statistical methods. RESULTS: There were significant differences in body weight between aerobic and strength training (P = 0.004) and aerobic and control groups (P = 0.018), body mass index between combined and strength training (P = 0.004) and combined and control groups (P = 0.001), fat percentage between aerobic training and control group (P = 0.017) and combined training and control groups (P = 0.004), and finally, fat-free mass between aerobic and strength training (P = 0.024), aerobic and combined training (P = 0.0001), strength and control groups (P = 0.035), and combined and control groups (P = 0.0001). CONCLUSIONS: The results indicated that 12-week workout, 20-60 min/session, 3 days a week of moderate intensity exercise improved body composition, ICAM-1, VCAM-1, and CRP compared to those who did not participate in any training. However, all three types of exercises had small benefits on body composition, ICAM-1, VCAM-1, and CRP in sedentary middle-aged men, and the importance of combined training required further investigations.
RESUMEN
Proper recognition and tracking of microscopic sperm cells in video images are vital steps of male infertility diagnosis and treatment. The segmentation and detection of sperms in microscopic image analysis is a complicate process as a result of their small sizes, fast movements, and considerable collisions. Histogram-based thresholding schemes are very popular for this purpose, since they are quite fast and provide almost acceptable results. This paper proposes a combined method for sperm cells detection, which consists of a non-linear pre-processing stage, a histogram-based thresholding algorithm, and a tracking method based on an adaptive distance scheme. The results of conducted experiments verify the superiority of the proposed scheme with incorporated Kittler algorithm compared to the other competitive methods in the majority of cases.

The aim of this study was to evaluate the effects of early postpartum PGF2α treatment on reproductive performance in dairy cows synchronized with targeted breeding and natural mating after voluntary waiting period. In this experiment ,120 cows were assigned to three groups irrespective of presence or absence of luteal tissue. Cows in PG- 14 group were treated with PGF2α from day 14 postpartum, cows in PG-28 group were treated with PGF2α from day 28 postpartum and cows in PG-42 group were not treated with PGF2α until the end of voluntary waiting period (d 42). After day 42 postpartum, cows in three groups were treated with PGF2α within 14-day intervals until natural mating after voluntary waiting period. Recorded reproductive parameters included days to first heat, days to first mating, days open, service per conception, conception rate, percentage of repeat breeder animals and pregnancy loss. Early PGF2α treatment from day 14 postpartum significantly decreased days to first estrus (34.9 ± 0.74, P < 0.003), days to first mating (62.35 ± 1.53, P < 0.04), days open (117.23 ± 3.1, P < 0.001) and service per conception (1.9 ± 0.09, P < 0.02); and PG-14 group presented increased conception rate (52.5%, P < 0.05). The proportion of repeat breeder syndrome tended to be affected by treatment with PGF2α from day 14 postpartum. In conclusion, treatment of cows with PGF2α from day 14 postpartum improved reproductive performance.(AU)
