Understanding the pathogenesis of certain viral agents is essential for developing new treatments and obtaining a clinical cure. With onset coronavirus (SARS-CoV-2) pandemic in beginning 2020, rush to conduct studies develop drugs has led publication articles that seek address knowledge gaps contribute global scientific research community. There are still no reports on infectivity or repercussi...

CBA/HT(6)T(6) bone marrow cells (1 x 10(7)) or CBA/H bone marrow cells (1 x 10(7)) plus CBA/HT(6)T(6) thymus cells (5 x 10(7)) were injected intravenously into lethally (800 R) irradiated CBA/H mice. Chromosome analyses of dividing cells in the host lymphoid and myeloid organs were performed at intervals after irradiation. Donor marrow cells settled and proliferated in the host bone marrow, spl...

Whereas most T cells arise in the thymus, a distinct lineage of extrathymically derived T cells is present in the gut mucosa. The developmental origin of extrathymic T cells is poorly understood. We show here that Notch-1, a transmembrane receptor involved in T cell fate specification of bipotential T/B precursors in the thymus, is absolutely required for the development of extrathymic (as well...

The volatile constituents of the aerial parts of two samples of Thymus longicaulis C. Presl, collected in Campania and in Sicily, and two samples of Thymus pulegioides L. from the same regions, were extracted by hydrodistillation and analyzed. Considering the four oils together, seventy-eight different compounds were identified: 57 for Thymus longicaulis from Sicily (91.1% of the total oil), 40...

a case of myiasis due to musca domestica describes in pseudocerastes persicus for the first time. the snake was found in bari karafs, kashan, iran, with a lesion on its body. fourteen live larvae of m. domestica removed from its wound. this is the first report of a new larval habitat of m. domestica .

1School of Public Health and Institute of Public Health Research, Tehran University of Medical Sciences, Tehran, Islamic Republic of Iran. Received: 14/04/03; accepted: 26/10/03 ABSTRACT Between 1991–2000, Leishmania species were isolated and characterized by isoenzyme and molecular analysis from rodents caught in various parts of the Islamic Republic of Iran. In areas endemic for cutaneous lei...

PURPOSE To evaluate the imaging appearance of the thymus in the myasthenic patients by using chemical shift magnetic resonance imaging, and, to correlate the chemical shift ratio (CSR) with pathologic findings after surgical excision. MATERIALS AND METHODS In the past year, a total of 11 myasthenic patients (4 males, 7 females; age range of 26-65 years), have been investigated by MRI centered...

The waterdistilled essential oil from dried aerial parts of one of the Algerian thymes, Thymus fontanesii Boiss. & Reut. grown in Setif province, Algeria, was analyzed by GC/MS. Fifteen components were characterized representing 99.4% of the total components detected. The major components of the oil were thymol (67.8%), gamma-terpinene (15.9%) and p-cymene (13.0%).

Although normal mice eliminated the lumen-dwelling intestinal cestode Hymenolepis diminuta by day 21 post-cysticercoid inoculation, congenitally thymus-deficient (nude) mice maintained their work burdens. Nude mice grafted with thymus glands or injected with thymus cells eliminated their worms.

The thymus is a lymphatic organ that undergoes dynamic changes with age and disease. It is important to be familiar with these physiological changes in the thymus gland to be able to identify pathology and make an accurate diagnosis. The thymus may be involved in multisystem disorders or show focal isolated lesions. The aim of this article is to review the radiological anatomy of the thymus, no...
