STORAGE AND RETRIEVAL OF MYCOBACTERIUM TUBERCULOSIS ON FILTER PAPER STRIPS

DNA fingerprinting of Mycobacterium tuberculosis complex culture isolates collected in Brazil and spotted onto filter paper.

The usefulness of filter paper for preservation of bacterial cells was shown by mixed-linker DNA fingerprint analysis of Mycobacterium tuberculosis isolates from 77 Brazilian patients. DNA fingerprints of samples spotted onto filter paper and conventional culture material were identical. Thus, filter paper specimens analyzed by an amplification-based typing method provide a new resource for epi...

the effect of translation versus matching words and definitions on retrieval of vocabulary among iranian intermediate efl learners

این تحقیق جهت بررسی تأثیر ترجمه در برابر ایجاد ارتباط بین لغات و ارائه معانی بر بازیابی واژگان در میان زبان آموزان متوسط ایرانی انجام شده است. به این منظور سه گروه کامل از دانش آموزان سطح متوسط که کتاب اینترچنج3 را مطالعه می کردند پس از انجام تست استاندارد مهارت سنجی انتخاب شدند. در ابتدا محقق آنها را به دو گروه آزمایشی و یک گروه کنترل یا شاهد تقسیم نمود و درمرحله بعد از کلیه دانش آموزان در سه ...

Evaluation of culture and PCR-based assay for detection of Mycobacterium tuberculosis from sputum collected and stored on filter paper.

We evaluated the use of culture and PCR-based assay for the direct detection of Mycobacterium tuberculosis (MTB) from sputum collected and stored on filter paper at room temperature for 5 days; the results were compared with those of staining and conventional culture of fresh sputum before storage (the 'gold standard'). Out of 231 sputum specimens examined, MTB was recovered from 124 samples by...

Stability of Specific Bacteriophage Stored on Filter-paper Strips for the Rapid Identification of Pasteurella Pestis.

Modeling storage and retrieval of memories in the brain

We have proposed a neural network model that stores the incoming information after orthogonalizing it in the same manner as vectors are orthogonalized. The scheme enables the brain to compare a new informational system with those in the memory and store its similarities and differences with the old memories in an economical manner. This allows the brain to have an enormous capacity and yet the ...
