            A Pituitary-Derived MEG3 Isoform Functions as a Growth Suppressor in Tumor Cells

            I obtain a page showing the following abstract:

            Abstract Human pituitary adenomas are the most common intracranial neoplasm. Typically monoclonal in origin, a somatic mutation is a prerequisite event in tumor development. To identify underlying pathogenetic mechanisms in tumor formation, we compared the difference in gene expression between normal human pituitary tissue and clinically nonfunctioning pituitary adenomas by cDNA-representational difference analysis. We cloned a cDNA, the expression of which was absent in these tumors, that represents a novel transcript from the previously described MEG3, a maternal imprinting gene with unknown function. It was expressed in normal human gonadotrophs, from which clinically nonfunctioning pituitary adenomas are derived. Additional investigation by Northern blot and RT-PCR demonstrated that this gene was also not expressed in functioning pituitary tumors as well as many human cancer cell lines. Moreover, ectopic expression of this gene inhibits growth in human cancer cells including HeLa, MCF-7, and H4. Genomic analysis revealed that MEG3 is located on chromosome 14q32.3, a site that has been predicted to contain a tumor suppressor gene involved in the pathogenesis of meningiomas. Taken together, our data suggest that MEG3 may represent a novel growth suppressor, which may play an important role in the development of human pituitary adenomas.

            Is there any command in R packages that could do the same? I have been playing with some tools like 'easyPubmed', 'Rentrez', etc, but I was a little intimidated by their complexity. Thanks in advance.

            Finding a rational approximation of a real number when both the numerator and denominator have a restricted range
            Asked 2021-Nov-04 at 16:35

            I'm trying to learn how to find a rational approximation of a real number when both the numerator and denominator are constrained. I've looked at many pages now, including the following two, and learned about the continued fractions method, the Farey sequence, and the Stern-Brocot tree. However, in all of these examples, either the numerator or denominator are unconstrained.

            Algorithm for simplifying decimal to fractions
            https://gist.github.com/mikeando/7073d62385a34a61a6f7

            Here's my situation:

            I'm testing mixed-signal ICs.
            In one of our tests, in order to find the IC's maximum operating frequency, the clock signal going into the IC is set to 12 MHz and continually decreased until the IC is able to run a simple digital sequence.
            The test platform's main clock has a range of 25 to 66 MHz, and the function that sets it takes in a double.
            In the current version of the test, it's set to a constant 50.0 MHz, then a function that divides that frequency is called in a loop. The divisor is an integer that can be anywhere between 1 and 4096.

            However, this results in imprecise measurements.
            The devices always pass at:
            50 / 5 = 10 Mhz
            50 / 6 = 8.333 MHz

            If possible, to get more precise measurements, I'd like to be able to change the main clock's frequency AND the clock divisor in each loop iteration. That's why I'm trying to learn how to write something like a continued fractions algorithm with constraints to both the numerator and denominator. I'm envisioning something like this:

            Since your range is so constrained, you could just brute force it. There's only 172,032 possible combinations of numerator and denominator to check. The algorithm could be made more efficient by iterating from 25 to 66 and calculating the closest two denominators, in which case you only have to check 84 possibilities:

Instead, you can push your attributes account.view.id and utm.marks into flow file using UpdateRecord and then you can just query for everything using *.

            But I need to show legend on right side, so i code chartArea: { right:'60%'} to create more space to show legend, it is causing no more space for bar width. Screenshot at below :

            How to save in two columns of the same file from different output in bash
            Asked 2021-Mar-30 at 16:43

            I am working on a project that require me to take some .bed in input, extract one column from each file, take only certain parameters and count how many of them there are for each file. I am extremely inexperienced with bash so I don't know most of the commands. But with this line of code it should do the trick.

            for FILE in *; do cat $FILE | awk '$9>1.3'| wc -l ; done>/home/parallels/Desktop/EP_Cell_Type.xls

            I saved those values in a .xls since I need to do some graphs with them. Now I would like to take the filenames with -ls and save them in the first column of my .xls while my parameters should be in the 2nd column of my excel file. I managed to save everything in one column with the command:

            ls>/home/parallels/Desktop/EP_Cell_Type.xls | for FILE in *; do cat $FILE | awk '$9>1.3'-x| wc -l ; done >>/home/parallels/Desktop/EP_Cell_Type.xls

            My sample files are:A549.bed, GM12878.bed, H1.bed, HeLa-S3.bed, HepG2.bed, Ishikawa.bed, K562.bed, MCF-7.bed, SK-N-SH.bed and are contained in a folder with those files only.

            The output is the list of all filenames and the values on the same column like this:

            Column 1 A549.bed GM12878.bed H1.bed HeLa-S3.bed HepG2.bed Ishikawa.bed K562.bed MCF-7.bed SK-N-SH.bed 4536 8846 6754 14880 25440 14905 22721 8760 28286

            but what I need should be something like this:

            Filenames #BS A549.bed 4536 GM12878.bed 8846 H1.bed 6754 HeLa-S3.bed 14880 HepG2.bed 25440 Ishikawa.bed 14905 K562.bed 22721 MCF-7.bed 8760 SK-N-SH.bed 28286 ...

            I'm using the HAPI hapi-structures-v25 library with version 2.3 to parse HL7v2 message & convert that into FHIR resources. I'm facing a strange issue while receiving and parsing the HL7V2 message using HAPI via TCP listener.

            Determine encoding for message. The following is the first 50 chars of the message for reference, although this may not be where the issue is: MSH|^~\&|OPENEMR|DrJhonDoe|TEST|UNKNOWN|20210216190432||ADT^A01^ADT_A01|60b647d4-b5a5-4fae-a928-d4a3849de3c8|T|2.5

            Answered 2021-Feb-22 at 07:07

            As you mentioned you are getting the message properly, I do not think this has to do with HL7. My first guess was this may be an issue related to byte to string conversion.

            But, while discussing with you in comments, you said MLLP characters are present in the string which is causing the problem.

            I am aware some MLLP parser remove the MLLP characters (, , ); but some does not. Application should remove them.

            After converting bytes to string and before calling parser.parse(hl7Message), simply remove those characters with some string replace method in Java.

            I do not know java, but something like hl7Message.replace(...., "") should work.
