BACKGROUND: Cartilage tear has begun to be treated with stem cells. However, cell oxygen level culture not been evaluated for the best environment enhance chondrogenesis. AIM: The purpose of this review is focus on hypoxic cells as a treatment cartilage tear. METHODS: A literature search was systemically conducted PubMed (MEDLINE), OVID, EMBASE, Cochrane Library, Scopus, Web Science, Science Di...
A nested PCR method was developed for the detection of Coxiella burnetii in human serum samples. Two pairs of oligonucleotide primers were designed to amplify a 438-bp fragment of the com1 gene encoding a 27-kDa outer membrane protein of C. burnetii. The primers amplified the predicted fragments of 21 various strains of C. burnetii but did not react with DNA samples from other microorganisms. T...
BACKGROUND It is widely agreed that the practices of clinicians should be based on the best available research evidence, but too often this evidence is not reliably disseminated to people who can make use of it. This "know-do" gap leads to ineffective resource use and suboptimal provision of services, which is especially problematic in low- and middle-income countries (LMICs) which face greater...
We report the detection of H13CN and HC15N in mid-infrared spectra recorded by the Composite Infrared Spectrometer (CIRS) aboard Cassini, along with the determination of the 12C/13C and 14N/15N isotopic ratios. We analyzed two sets of limb spectra recorded near 13–15◦ S (Tb flyby) and 83◦ N (T4 flyby) at 0.5 cm−1 resolution. The spectral range 1210–1310 cm−1 was used to retrieve the temperature...
rice (oryza sativa l.) is one of the iran's most strategic crops with water shortage as the most important abiotic stress limiting its yield. in the present research the effects of: variety, water regime, nitrogen (n) and phosphorus (p) levels on n, p and k uptake were studied under greenhouse conditions. the experiment design was a factorial one based upon a randomized complete blocks of ...
The calculation of conductivity electron concentrations in n -GaSb at T = 295 K and 77 have been made. concentration “heavy” electrons the L-valley conduction band Т has shown to exceed “light” one Γ-valley. On contrary, are gathered Γ-valley.The results Hall measurements made on tellurium-doped samples n-GaSb obtained by Czochralski method represented. It that upon analysing data K, it is nece...
In view of the pipeline marking difficult and poor measurement precision, a new-type monolithic integrated array MEMS vector vibration sensor has been put forward. It has overcomed the deficiency that present vector acoustic sensor applied in the oil and gas pipeline internal inspector can not be accurate about signal position, and eliminated the port/starboard blur problem. Through ANSYS simul...
