Unix / Mac OSX: How to find a strings in multiple files?

Posted on in Environment Unix

Ever need to search through all your files for a certain word or phrase? You will need the grep command for this. Handy, and it's recursive, which means you can search through your entire directory tree, scanning every file along the way.

grep -r "foo" /mypath

The "-r" switch, tells "grep" to scan files in the current directory and all sub-directories.

Installing Node and NPM on MAC OSX

Posted on in Environment Node JS

Node.js is a platform built on Chrome?s JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

This assumes that Git is already installed and available on the command-line. Since the technology Node.js is quiet new, check at http://nodejs.org/ what the latest stable version of node.js is. For this example the latest version is v0.6.14. Open your terminal and start typing the following commands:

$ git clone git://github.com/joyent/node.git
$ cd node
$ git checkout v0.6.14
$ ./configure
$ make
$ sudo make install

Now Node.js is installed, you should also download the Node Package Manager. It?s no longer necessary to install npm separately, but if you want you can install this via the command-line as well. Use the following command:

$ curl http://npmjs.org/install.sh | sh

As an extra let?s also install MongoDB, is a large scalable high performance NoSQL database.

$ npm install mongojs

Compelling evidence exists for pervasive sex differences in pathological conditions, including anxiety and depressive disorders, with females more than twice as likely to be afflicted. Gonadal hormones may be a major factor in this disparity, given that women are more likely to experience mood disturbances during times of hormonal flux, and testosterone may have protective benefits against anxiety and depression. In this review we focus on the effects of testosterone in males and females, revealed in both human and animal studies. We also present possible neurobiological mechanisms underlying testosterone's mostly protective benefits, including the brain regions, neural circuits, and cellular and molecular pathways involved. While the precise underlying mechanisms remain unclear, both activational and organizational effects of testosterone appear to contribute to these effects. Future clinical studies are necessary in order to better understand when and how testosterone therapy may be effective in both sexes. testosterone.

Oocyte maturation in fish is a hormonally regulated process. In the light of long-term oocyte maturation in beluga, the aim of this research was to study the estrogenic effects of different concentrations of soy dietary genistein (GE) and equol (EQ) on the growth performance and ovary development in farmed female Huso huso. Fish were fed with concentrations 0 (control), 0.2, 0.4, 0.8 and 1.6 g of EQ and GE per kg of isoproteic (CP 45 %) and isoenergetic (19.5 MJ/kg) diets during a year. Blood samples and ovary biopsies were collected from each fish seasonally. The main results of the present experimentation are that growth performance was not affected significantly both in GE and EQ (P > 0.05). EQ at concentration 0.4 g/kg had more estrogenic effects than other concentrations of EQ and GE in beluga so that 64 % of fish were matured sexually. Some reproductive indices such as oocyte diameter, testosterone (T) and 17?-estradiol (E?) increased significantly at EQ 0.4 g/kg at the end of experiment (P < 0.05), while 17?-hydroxy progesterone level (17?-OHP) showed no significant changes at all concentrations. Biochemical indices such as calcium, phosphorous and cholesterol increased at GE concentrations, but decreased at EQ concentrations similarly at the end of experiment. There was a negative relationship between plasma phosphorous and alkaline phosphatase enzyme levels. Based on results, EQ at concentration 0.4 g/kg improved oocyte development more than the other concentrations of GE and EQ, and therefore, it can be used as an additive to diets for inducing ovary development in this species. testosterone.
