Rare report of concurrent metastasis on bilateral atrial myxoma masses.

Background: This study simultaneously reports bilateral atrial tumor masses including the concurrent occurrence of metastatic carcinoma, consistent with metastatic breast carcinoma, on the main cardiac myxoma mass in the left atrium (LA) and metastatic carcinoma consistent with metastatic breast carcinoma for the right atrial (RA) mass.

Case Report: These masses were observed in a 79-year-old female patient who had received her pacemaker 6 months ago due to electrical conduction disease. However, no tumor/mass was found in her echocardiogram at the time of the pacemaker reception and mild chest pain and dyspnea were the only signs of her huge masses.

Evaluating the Effects of Experiencing Virtual Reality Simulation of Psychosis on Mental Illness Stigma, Empathy, and Knowledge in Medical Students.

Objectives: Applying technologies such as virtual reality (VR) in education has gained popularity especially in comprehending abstract and subjective phenomena. Previous studies have shown that applying a virtual reality simulation of psychosis (VRSP) is useful in increasing knowledge and empathy toward patients. Here, the efficacy of using VRSP in altering stigma, empathy and knowledge as well as side effects have been assessed in medical students in comparison with the routine education (visiting the patients).

Association of COVID-19 and other viral infections with interstitial lung diseases, pulmonary fibrosis, and pulmonary hypertension: A narrative review.

Background: Interstitial lung diseases (ILDs) include a broad range of diffuse parenchymal lung disorders and are characterized by diffuse parenchymal lung abnormalities leading to irreversible fibrosis. ILDs are correlated with the occurrence of pulmonary fibrosis (PF), which generally also results in pulmonary hypertension (PH). Interferons, secreted in larger amounts during viral infections, are an important possible risk factor contributing to this outcome.

and , Potent Lethal/Repellent Agents against , Probable Carrier for Zoonosis.

Background: is a hard tick with importance in transmission of tick-borne diseases and zoonosis. Natural products are excellent alternative to pesticides. In this study for the first time, lethal and repellent activity of and against were studied.

In-vitro antigiardial activity and GC-MS analysis of Eucalyptus globulus and Zingiber officinalis essential oils against Giardia lamblia cysts in simulated condition to human’s body.

In order to finding of potent natural medication/agent which can kill giardial cysts in the interval between lysing of outer membrane of cysts due to exposure by acidic condition of stomach and their encystation in proximal small intestine, In-vitro antigiardial activity and GC-MS analysis of Eucalyptus globulus and Zingiber officinalis against Giardia lamblia were studied in simulated condition to human’s body singly and in combination. Essential oils were extracted and their chemical components were identified via GC-MS method. After purification, cysts were exposure to acidic condition and were challenged by different concentrations of essential oils in simulated condition to human’s body.

Mutations of Voltage-Gated Ionic Channels and Risk of Severe Cardiac Arrhythmias.

Background: Arrhythmias as important malfunctions of heart are known as abnormal rhythm of heart. Several causes can make arrhythmias and most of them are related to generation and/or conduction of action potential in heart. Action potential in myocytes results from the sequential opening and closing of ion channel proteins that span the plasma membrane of individual myocytes.

The insecticidal and repellent activity of ginger (Zingiber officinale) and eucalyptus (Eucalyptus globulus) essential oils against Culex theileri Theobald, 1903 (Diptera: Culicidae.

Insecticidal and repellent activity of essential oils of Zingiber officinale and Eucalyptus globulus against Culex theileri Theobald, 1903 as a wide-distributed species of mosquitoes in different parts of world with an important role in transmission of infectious organisms and agent were studied. Essential oils were extracted from fresh parts of plants and different concentrations of 250 μl/ml, 500 μl/ml, 750 μl/ml and 1 (undiluted extract) were prepared for each of essential oils. Insecticidal and repellent activity of essential oils against adult form of Culex theileri Theobald mosquitoes, collected from small pools located near the Zayande-Rood River in the Saman city, Iran, were examined via direct exposure method and Y-tube olfactometer bioassay, respectively.

Effect of heat stress on the gene expression of ion transporters/channels in the uterus of laying hens during eggshell formation.

Heat stress is a problem in laying hens as it decreases egg quality by decreasing eggshell mineralization. Heat stress alters gene expression, hence our aim was to investigate effects of heat stress on gene expression of ion transport elements involving in uterine mineralization (TRPV6, CALB1, ITPR3, SCNN1G, SLC4A4, KCNJ15, SLC4A9, and CLCN2) by real time quantitative PCR. Forty 23-week-old White Leghorn laying hens were housed in two rooms.

Effect of infection on the hemogram of the Pigeons ().

It has been reported that parasites affect the health and productivity of birds, initiate excessive preening which interrupts feeding, as the birds spend much time preening rather than being involved in other essential life activities. occurs in pigeons widely in tropical and subtropical regions. The present investigation was concentrated on the effect of infection on the hemogram and changes in the number of white blood cells in infected pigeons.

A First Report of Infestation by Pseudolynchia canariensis in a Herd of Pigeons in Shahrekord (Southwest of Iran).

Background: Pigeons (Columba livia) have been kept as pet and reared for food in several countries including Iran. Ectoparasites are regarded as the basic causes of retardation in growth, lowered vitality and poor conditions of the birds. Pseudolynchia canariensis a hippoboscidae fly is one of the important ectoparasites of pigeons and is responsible for the transmission of pathogens to birds and humans same as pathogenic protozoan Haemoproteus columbae.

Prevalence of Linguatula serrata nymphs in slaughtered sheeps in Isfahan province, southwest of Iran.

Linguatula serrata, well known as tongue worm; is an aberrant cosmopolitan parasite, which inhabits the carnivorous mammals (especially Canidae) respiratory system. The discharged eggs infect many plant feeder animals including human that produces visceral and nasopharyngeal linguatulosis which is known as Marrara syndrome in man. In current study, the prevalence rate of infection with L.

A report on the genital myiasis by Wohlfahrtia magnifica in camel herds in southwest of Iran.

Myiasis is a disease of vertebrate animals caused by different fly larvae. Wohlfahrtia magnifica is responsible for serious losses in animal husbandry in Eurasia. Larvae of W.

Comparison of the anticoccidial effect of granulated extract of Artemisia sieberi with monensin in experimental coccidiosis in broiler chickens.

Coccidiosis is the most important parasitic disease of the poultry production industry. Due to increasing resistance to conventional anticoccidial agents, it is necessary to find new anticoccidial compounds. Herbal compounds such as those from Artemisia species are promising weapons in this regard since preliminary studies have shown its anticoccidial effects.

Prevalence and Rate of Parasitemia of Haemoproteus columbae in Columba Iiviadomesticain Southwest of Iran.

Background: Parasites affect the health and productivity of birds. Haemoproteus columbae occurs in pigeons widely in tropical and subtropical regions. The present investigation was concentrated on the prevalence of H.
