    Abstract Cryptosporidiosis, giardiasis, and blastocystosis are among the most important parasitic diseases common between humans and cats. In addition, there are concerns about the possible transmission of zoonotic parasites from infected cats to humans. Hence, we investigated the molecular epidemiology of Cryptosporidium spp., Giardia duodenalis, and Blastocystis sp. in stray and household cats and cat owners. Our study was performed on 132, 33, and 33 fecal samples of stray and household cats, as well as cat owners in Tehran, Iran. Cryptosporidium spp. was identified using a nested PCR targeting the small subunit ribosomal RNA gene (SSU rRNA) and sequencing the internal amplified fragments. Furthermore, to perform multilocus genotyping of G. duodenalis, the ß-giardin (bg), glutamate dehydrogenase (gdh), and triosephosphate isomerase (tpi) genes were amplified to assess the DNA of G. duodenalis in the fecal samples of cats and cat owners. In addition, Blastocystis was detected by targeting the SSU rRNA gene, and the subtypes of Blastocystis were determined via the sequencing of amplicons. Cryptosporidium felis and Cryptosporidium canis were detected in seven stray cats (5.3%) and one household cat (3%). The bg gene of G. duodenalis was amplified and successfully sequenced in two (1.5%) stray cats and revealed assemblages F and B of G. duodenalis. Sequencing and phylogenic analysis of SSU rRNA gene nucleotide sequences of Blastocystis detected ST5 and ST10 in stray cats (1.5%), ST1 in household cats (9.1%), and ST1, ST2, ST3, and ST7 in owners (30.3%). The low prevalence of Cryptosporidium, Giardia and Blastocystis in cats and the presence of species/assemblages/subtypes with limited zoonotic potential indicate that cats had a minor role in their owners' infection in the investigated population. However, the presence of zoonotic protozoa in cats suggests the necessity of special attention to high-risk individuals during close contact with cats. Therefore, it is recommended that veterinarians, physicians, and urban managers plan to prevent, control, or treat these parasites to help the urban community live healthily alongside cats.

    Abstract Background: Cutaneous leishmaniasis (CL) is a Neglected Tropical Disease (NTD) that causes high morbidity in the tropics and sub-tropics. Despite the remarkable advancements in the treatment of CL, the available therapeutics are far from ideal and also cause serious adverse side effects. Negative air ions (NAIs) generators are widely available for domestic and industrial uses. Several studies have reported on positive effects of NAIs therapy on human health as a non-pharmaceutical treatment for respiratory disease, allergy, or stress-related health conditions, including infectious diseases. To our knowledge, no studies have examined the effectiveness of the NAIs therapy against Leishmania parasites. The aims of this study were to investigate the effect of NAIs therapy on Leishmania major (L. major) the causative agent of CL in in vitro and in a murine model.
    Methodology/principal findings: In vitro anti-leishmanial effects of NAIs therapy were measured by parasitological methods. NAIs therapy was assessed in vivo in L. major infected BALB/c mice by measuring the footpad (FP) lesion size and parasite load using metric caliper tool and qPCR, respectively. Immune responses in treated and non-treated mice were assessed by measuring the levels of IFN-γ, IL-4, NO and arginase activity. In vitro NAIs therapy significantly decreased the viability of Leishmania promastigotes and of amastigotes cultured in macrophages, but did not affect the host cells. NAIs therapy of L. major infected BALB/c mice resulted in reduced FP lesion size, diminished parasite burden, and importantly decreased induction of IL-4 and arginase activity in the presence of NAIs. In contrast IFN-γ and NO levels were significantly enhanced. NAIs therapy significantly diminished the progression of disease compared to the control group, but was less effective than amphotericin B treatment.
    Conclusions: Our study shows that NAIs treatment was effective in vitro and in Leishmania-infected mice, elicited a T-helper 1 (Th1) response and increased efficient cellular immunity, resulting in a diminished parasite load. Therefore, NAIs therapy can be considered as a useful and safe tool that can contribute to clearing L. major infections without inducing toxicity in host cells. The applications and mechanisms of NAIs therapy warrant further investigation especially in humans suffering from CL.

    Abstract Introduction: It is known that ischemia-reperfusion causes remote organ injury as well as local injury. In traditional systems of medicine, many plants have been documented to be useful for the treatment of various disorders including oxidative esters. This study was designed to investigate whether Otostegia persica extraction pretreatment has a protective effect against renal injury induced by hindlimb ischemia-reperfusion.
    Methods: Forty male Wistar rats were allocated into five groups as follows: Control, Sham, Otostegia persica, ischemia-reperfusion and ischemia-reperfusion+Otostegia persica groups. Rats in Otostegia persica and ischemia-reperfusion+Otostegia persica groups received Otostegia persica extraction (300 mg/kg) orally 2 days prior to operation. Hindlimb ischemia was induced by clamping the femoral artery for 2 h. After 24 h of reperfusion, blood and urine samples were obtained for kidney function tests and the kidneys were removed for histological analysis and oxidative stress measurement.
    Results: The decrease in glomerular filtration rate induced by reperfusion was significantly improved by Otostegia persica extraction administration (P<0.05), which resulted in the decrease in serum urea and creatinine concentrations. Urinary creatinine significantly decreased in ischemia-reperfusion group compared to the other groups (P<0.05). Urinary excretion rate, water intake and the ratio of kidney/body weight significantly increased in animals with reperfusion injury as compared with other groups (P<0.05). On histological examination, rats pretreated with Otostegia persica extraction had nearly normal morphology. Skeletal muscle ischemia-reperfusion produced a significant increase in renal tissue malondialdehyde level, while pretreatment with Otostegia persica extraction was associated with a significantly lower malondialdehyde level (P<0.05). Renal tissue catalase and superoxide dismutase activity and glutathione level were significantly (P < 0.05) decreased by hindlimb ischemia-reperfusion. The increases in these parameters were decreased by pretreatment with Otostegia persica extraction.
    Conclusions: The results of this study showed that Otostegia persica extraction pretreatment significantly protected the renal injury from skeletal muscle ischemia-reperfusion.

    Abstract Introduction: Tramadol has been shown to decrease ischemia-reperfusion injuries in myocardial or brain tissues. The aim of this study was to assess the effects of tramadol on ischemia-reperfusion injury in a rat hind limb ischemia-reperfusion model.
    Methods: Forty-five healthy adult male Wistar rats were randomized into three experimental groups as follows: Sham, Ischemia-reperfusion and Ischemia-reperfusion + tramadol groups. Ischemia was induced in anesthetized rats by left femoral artery clipping for 2 h followed by 24 h of reperfusion. Tramadol (20 mg/kg) was administered intravenously immediately prior to reperfusion. Blood pH, pO2, pCO2, HCO3, creatine phosphokinase (CPK), lactate dehydrogenase (LDH) as well as plasma malondialdehyde (MDA) were measured at the end of the reperfusion. Left gastrocnemius muscle samples were taken for histological and biochemical examination.
    Results: The pH and pCO2 were similar in all study groups, with no statistical significance. pO2 and HCO3 levels presented the highest elevation in sham and Ischemia-reperfusion + tramadol groups, as compared to Ischemia-reperfusion group (P < 0.05). The extent of muscle changes in the ischemia-reperfusion + tramadol group was significantly lower than ischemia-reperfusion group (P < 0.05). In comparison with other groups, serum and tissue MDA levels in ischemia-reperfusion group were significantly increased (P < 0.05). The muscle tissue glutathione (GSH), superoxide dismutases (SOD) and catalase (CAT) levels in the Ischemia-reperfusion group were significantly lower than the other groups (P < 0.05). Wet/dried weight ratio in ischemia-reperfusion group was significantly higher (P < 0.05) than subjects in other groups.
    Conclusions: From the histological, histochemical and serum biochemical perspective, the treatment with tramadol has alleviated the metabolic injuries in the skeletal muscle ischemia and reperfusion in this experimental model.
