background: inversion of the uterus is very uncommon. patients may present with pelvic pain, vaginal discharge, or hemodynamic shock. case: we report a case of 35 years old women (virgin) who was admitted with profuse vaginal bleeding and cramps of uterus. in the vaginal examination at litothomy position a mass of 58 cm in size was protruded from the vagina. at first myomectomy was performed a...

TLR signaling is associated with the transcription of various proinflammatory cytokines, including TNF-α, IL-6, and IL-1β. After transcription, the mRNA of these proinflammatory cytokines needs to be tightly controlled at the posttranscriptional level to achieve an optimal expression. However, the precise mechanism of posttranscriptional regulation is not fully understood. In the current study,...

poly (n-bromosuccinimide) (pnbs) as a mild, efficient, non-acidic, polymeric and heterogeneous catalyst was applied for simple conversion of epoxides into thiiranes by treatment with kscn or (nh2)2cs at room temperature. aliphatic and aromatic epoxides converted into their corresponding thiiranes under mild conditions. all reactions proceeded in short reaction times and afforded the correspondi...

in this research, zeolite a was synthesized from waste porcelain and cds nano-particles were doped in zeolite framework by a precipitation after an ion exchanging process. all raw and modified samples were characterized by ft-ir, xrd and sem methods. primary experiments showed that the good efficiency of loaded nano cds onto the zeolite a for photodecomposition of dimethyldisulfide (dmds) under...

background:  radiochromic film is used for radiation dose measurement, xr-rv3 is used in fluoroscopy and ebt2 film in radiation therapy. the aim was to determine if the dosimetric properties of these two films are comparable in megavolt photon beams. materials and methods: comparison measurements included: calibration curves, heterogeneous phantom dose profiles, and nasopharynx dose distributio...

in the present study, the synthesis of diethylene triamine supported on cellulose biopolymer as a biodegradable solid basic heterogeneous catalyst was suggested. then, the applicability of the synthesized catalyst cellulose bonded n-propyl diethylene triamine (cbpdeta) was tested for the synthesis of oxindole derivatives, an important class of potentially bioactive compounds. a various series o...
