To compared the consistency regarding tubal patency diagnosis among delayed films at 4h, 6h and 24h after hysterosalpingography (HSG) with ethiodized poppy-seed oil, so as to explore effect of shortening retardation image on diagnosis. This study retrospectively enrolled 29 spontaneous menstrual, HSG indication qualified females, who underwent oil for assessment. During operation, plain film, u...

two potassium oxalate doped tio2 samples, designated as k1-tio2 and k2-tio2, were synthesized by the base-catalyzed sol-gel process. these samples were impregnated into rubber sheets. two commercial tio2 samples, anatase and degussa p25, were used as reference materials with which the synthesized samples were to be compared. anatase and p25 were also impregnated into rubber sheets and designate...

Mục tiêu: Một nghiên cứu mô tả tiến được thực hiện trên 195 người bệnh CTSN phẫu thuật tại BV Việt Đức nhằm kết quả chăm sóc sau Bệnh viện Hữu nghị năm 2022. Kết quả: Sau 6h, tỷ lệ phải thở máy là 25,6%, bóp bóng 2,1%. Vào ngày 2 mổ và khi ra chỉ có 4,0% 4,3% máy, sự khác biệt ý nghĩa thống kê với p < 0,001. thuật, hầu hết đường thông thoáng. theo dõi hô hấp đầy đủ. Theo tri giác: Ở thời điể...

We have substantially expanded the chemical phase space of hitherto unique γ-Ba4Nb2O9 type structure by designing and synthesizing stoichiometric ordered analogues γ-Ba4V1/3Ta5/3O9 γ-Ba4V1/3Nb5/3O9 exploring solid-solution series γ-Ba4VxTa2–xO9 γ-Ba4VxNb2–xO9. Undoped Ba4Ta2O9 forms a 6H-perovskite phase, but with sufficient V doping γ-type is thermodynamically preferred possibly more stable th...

ABSTRACT. A series of nine new 6-aryl-7-alkyl/aryl-[1,2,4]triazolo[4,3-a][1,3,5]triazine-5(6H)-thiones (2a-i) were synthesized by a reaction N-triazol-3-yl imidates (1) with three different isothiocyanate derivatives (RNCS) in refluxing toluene. The structures the final heterocyclic compounds confirmed 1H-NMR, 13C-NMR, FT-IR, elemental analysis, and mass spectral analysis. target vitro screened...

A novel synthesis of Iimidazo[1,2-c]quinazoline-5(6H)-thione framework was developed through a three-step reaction starting from benzil. The resulting (2-nitrophenyl)-4,5-diphenyl-1H-imidazole  from the reaction of benzil and different 2-nitrobenzaldehyde, reduction of nitro group and then cyclization reaction with carbon disulfide (CS2). All steps were carried out under easy and user-friendly ...
