Working in a Drupal agency you do a lot of drupal development and come against various problems. Recently, on a migration to Drupal I encountered a new problem with the Drupal database abstraction layer. It turns out that drupal dynamic select queries do not escape column names.

This problem does not touch each database type, but it definitely can be problematic when it comes to mysql

$query = Database::getConnection('default', 'legacy') ->select('prod_group', 'pg') ->fields('pg', array('porductid, 'active', 'order'));

will create the following query:

SELECT pg.productid AS productid, pg.active AS active, pg.order AS order FROM {prod_group} pg;

We are missing the “ around fields and in this scenario we had a very unfortunate column name “order” which is a reserved keyword in mysql used to sort  results (ORDER BY). This is how mysql interprets the query, which is therefore incorrectly structured and throws an error.

SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax;

We should be creating a query with table names escaped with backticks:

SELECT pg.productid AS `productid`, pg.active AS `active`, pg.order AS `order` FROM {prod_group} pg;

but Drupal does not support this in dynamic queries, which are the only ones supported by migrate module.

Solution – field aliases

Drupal supports aliasing. You can even see this above “pg.order AS order” is a query which aliases the order field automatically, unfortunately with it’s own restricted name.

But we can set these aliases automatically with SelectQueryInterface::addField.

$query = Database::getConnection('default', 'legacy') ->select('prod_group', 'pg') ->fields('pg', array('groupid', 'active')) ->addField('pg', 'order', 'escaped_order');

Which gives us a query without a restricted keyword:

SELECT pg.productid AS productid, pg.active AS active, pg.order AS escaped_order FROM {prod_group} pg;.

This solves the problem. Just remember that when you fetch your results, the order will be called escaped_order.

Peptides containing the Asn-Gly-Arg (NGR) motif are known to bind CD13 isoforms expressed in tumor vessels and have been widely used for tumor targeting. Residues flanking the NGR sequence play an important role in modulating the binding affinity and specificity of NGR for the CD13 receptor. Herein, we have used a rapid, easy, and reliable peptide array–whole cell binding assay for screening a library of NGR peptides with different flanking residues. A peptide array consisting of forty-five NGR containing peptides was synthesized on a cellulose membrane, followed by screening against CD13 positive (HUVEC and HT-1080) and CD13 negative cell lines (MDA-MB-435 and MDA-MB-231). The library screening led to the identification of five cyclic and acyclic NGR peptides that display higher binding (up to 5-fold) to CD13 positive cells with negligible binding to CD13 negative cell lines when compared to the lead sequence cyclic CVLNGRMEC. Peptides with high binding affinity for the CD13 positive cells also showed improved in vitro cellular uptake and specificity using flow cytometry and fluorescence microscopy. Interestingly, the identified peptides resemble the NGR sequences present in the human fibronectin protein. These NGR peptides are promising new ligands for developing tumor vasculature targeted drugs, delivery systems and imaging agents with reduced systemic toxicity.

Having to reach up and scratch your scalp is distracting and frustrating, and if you rub too much, you could end up with sore, painful broken skin. An itchy scalp, also known as scalp pruritus, has a wide range of causes. Keep reading to find out what can cause the itch, and discover the soothing, all-natural products to calm and balance your delicate scalp.

7 Reasons for an Itchy Scalp

An itchy scalp often comes in the form of dandruff and seborrheic dermatitis. For some people, an itchy scalp can be temporary, with itchy patches subsiding quickly, but for others, it can be an ongoing problem. If you’re struggling with an itchy scalp, here are some possible causes.

1. Dandruff

Dr. Anna Chacon, a board-certified dermatologist and published author based in Miami, Florida, told VEGAMOUR, “Dandruff is a common cause of itching. When dandruff irritates the scalp, the outer skin layer sheds to combat the inflammation, causing it to feel itchy. Dandruff is caused by dead cells of the skin, which drop off the scalp and appear as white flakes on the hair.”

The development of a fungus known as Malassezia yeast is the primary cause of dandruff. Malassezia relies on sebum and the scalp’s natural oils to nourish the dandruff-causing fungus. So even if you don’t see noticeable flaking on your scalp, you might still develop dandruff if your scalp is unhealthy. Severe dandruff is also called seborrheic dermatitis, and if the problem persists, it’s worth checking in with a dermatologist to get specialist care.

What it feels and looks like: White flakes and a near-constant itchy scalp.

Causes: An overly oily scalp or a buildup of dead skin cells, styling products or Malassezia

To get relief: You might also try using natural remedies such as peppermint oil or tea tree oil with a bacterial or fungal infection with seborrheic dermatitis. Menthol essential oil and peppermint oil can have a particularly soothing effect on the skin if you suffer from seborrheic dermatitis.

2. Scalp Psoriasis

Psoriasis commonly appears on the elbows, around the knees and along the body’s trunk, but did you know it can also show up on your scalp?

“A flare-up on the scalp occurs in approximately 50% of people with plaque psoriasis,” said Dr. Velusamy MP of iCliniq. “Reddish patches, dandruff-like flaking, silvery-white scale and a dry scalp are all possible. Scalp psoriasis is frequently itchy, with itch ranging from mild to severe. Skin conditions, such as scalp psoriasis, impact the hair follicles as patches cover the scalp, preventing hair from growing as it should. As a result, those affected can experience hair loss, worsening if the flaky skin is hand-picked off.”

What it feels and looks like: You’re itching one specific spot, your skin feels raised and you notice scaly patches.

Causes: Scalp psoriasis is an autoimmune condition that tends to be genetic. Stress, a weak immune system, hormonal changes and dry weather can exacerbate the situation.

To get relief: Seek advice from a dermatologist who might suggest shampoo with coal tar or salicylic acid to soothe the area. One study also found that zinc pyrithione can significantly reduce the itch intensity. Apple cider vinegar may be effective in relieving a psoriasis-related itchy scalp because it has antifungal properties. The National Psoriasis Foundation suggests diluting one part organic apple cider vinegar in one part water and applying it to the scalp. Rinse your scalp with water after the solution has dried. Avoid this remedy if you have open wounds or your skin is cracked or bleeding.

3. Allergic Reactions

“An itchy, dry and flaky scalp could signify that you must rinse the shampoo out of the hair more thoroughly,” advised Velusamy. “Leaving shampoo on the scalp can irritate. An itchy scalp could also be due to allergic contact dermatitis. People who dye their hair frequently experience this. The culprit is frequently a dye ingredient called para-phenylenediamine (PPD), which is found in black hair dyes. It could also be an allergic reaction to a shampoo, conditioner or other product that comes into contact with the scalp.”

What it feels and looks like: Your scalp might feel unbearably itchy, oily or greasy. In addition, if you use many hair products, you might further irritate the area.

Causes: Various ingredients in some hair products can irritate. If you’ve started using a new product, that could be the culprit.

To get relief: Consider non-toxic, moisturizing hair products with anti-inflammatory properties.

4. Head Lice

Velusamy said that you can get head lice by having close contact with someone who has it or by sharing items that they’ve used, such as a hat, brush or comb.

What it feels and looks like: Head lice can create a creepy, crawly, itchy feeling all over the scalp. Lice feed on human blood and lay their eggs near the roots.

Causes: As mentioned, sharing a hairbrush or coming into close contact with someone with lice will likely be the cause because lice are highly contagious.

To get relief: Use permethrin shampoo. You’ll also need to comb out the lice and the eggs to ensure the scalp is clear. If the problem persists, discuss the issue with a doctor. Tea tree oil may also help with a lice-related itchy scalp.

5. Actinic Keratosis

Actinic keratosis, aka sun damage, can lead to growths and dry, scaly patches across the scalp. These legions are often considered pre-cancerous, so you must get any signs checked out with a doctor.

What it feels and looks like: The skin can feel dry, scaly and like sandpaper. Patches are usually 1cm to 2cm in size, and the color ranges from pink to red or brown.

Causes: This skin condition grows slowly and can develop over time due to consistent sun exposure. It is often found on the scalp, ears, lips and the back of the head.

To get relief: Reduce sun exposure and use sunscreen daily. Talk to your doctor about prescription creams and gels. You might also discuss freezing the patches or even removal surgery.

6. Scalp Dysesthesia

Scalp dysesthesia is actually a cervical spine condition that can cause itching around the scalp.

What it feels and looks like: This condition can be very itchy, and sufferers might also experience a burning sensation.

Causes: If you have ever experienced a traumatic head or neck injury that impacts the spinal cord and then experienced itching, you could have this neurological condition. It’s a nerve-related itch that can signal physical or psychological distress.

To get relief: Speak to a doctor and don’t panic. This condition is usually seen in elderly patients, and the key treatment is a low dose of antidepressants.

7. Atopica dermatitis

Atopic dermatitis is an inflammatory skin condition commonly known as eczema. It can occur anywhere on the body, including the scalp, and it’s very itchy.

What it feels and looks like: You’ll notice itchiness around the scalp, and you might spot some redness. 

Causes: Atopic dermatitis is usually hereditary, and you might experience it if other family members have it too.

To get relief: Speak to a dermatologist to ensure a proper diagnosis and treatment plan. 

Nourish Your Scalp

An itchy scalp is deeply irritating and can be a symptom of many different conditions. You can use at-home remedies to resolve the issue, but if the itching is severe or you experience broken skin or open wounds, consult with your doctor.

Healthy hair starts with a healthy scalp. To keep your scalp balanced, healthy and itch-free from day to day, commit to using calming, natural products that remove buildup, moisturize, protect and soothe!

The global chemical company OQ Chemicals has resumed production at its sites in Oberhausen and Marl. The failure of a supplier’s synthesis gas plant had previously had previously led to OQ Chemicals having to declare “force majeure” for certain products.

During the temporary interruption of operations, OQ Chemicals implemented strategic improvements to optimise production processes, including data flows and workflows in plant management, operational technology and engineering. The company is thus increasing the efficiency and reliability of its plants and driving forward digitalisation and process development in line with its corporate strategy.

“We are delighted to be able to ramp up our plants in Germany again,” said Albrecht Schwerin, COO of OQ Chemicals. The unforeseeable shutdown was not exactly easy for OQ Chemicals, as the company has reported high customer demand since the beginning of the year. As an alternative, customers were supplied from other OQ Chemicals sites to minimise the impact on their operations and supply chains.

Global chemical and ingredient distributor Univar Solutions has been appointed as distributor of Cabot Corporation’s specialty carbon black products for the plastics and batteries markets in Brazil.

The agreement builds on the companies’ existing relationship. Cabot’s specialty carbon black products are used for multiple applications in the automotive market, including helping improve the efficiency, durability, performance and lifetime of hybrid and electric vehicle batteries. In addition to batteries, the versatility of carbon black products make them well-suited for other specialty applications such as plastics, consumer electronics and industrial parts, delivering value through a range of functionalities including colour, ultraviolet (UV) protection, surface smoothness and conductivity.

“As we continue growing our ingredients and specialties business in Latin America, it’s critical that we partner with world-class suppliers who are also committed to helping meet customers’ product performance needs while keeping sustainability top-of-mind. The addition of Cabot’s specialty carbon black products to our expansive product portfolio allows us to better serve those looking to innovate, grow and differentiate their business,” said Jorge Buckup, president of Latin America for Univar Solutions.

“Customers will benefit”

“We’re excited about our collaboration with Cabot in Brazil, which further expands a key supplier relationship and adds to our product offering to our customer base,” said Chris Fitzgerald, global vice president, CASE, Rubber and Plastic Additives for Univar Solutions. “We are confident our customers will benefit from the consistent focus we bring within the plastic compounding and battery markets, backed by strong local and technical support and commercial excellence.”

For six months or so jeggings has been a hard find, an expensive endeavor or an unflattering experience. Now I am happy to report that anyone who wishes to try out and purchase this legging jean should stop into Gap. They have six washes to please everyone, an incredibly flattering fit, a refreshing range of sizes (00-20 with tall and petite options) and did I mention they are yum-yum comfortable? They are, I stopped in yesterday to try them on.

Some perks to mention for those on the fence about jeggings, this is a thick yet stretchy material that will cover any skin flaws and reveal svelte legs and a tight ass. I couldn't believe how thin I looked in them. The waist isn't very low either. It almost reaches my belly button in a sexy retro way. I also like that you can get away with wearing shorter tops with them, unlike traditional leggings.

When buying or ordering these babies, order a size smaller than usual because the fabric is already stretchy and it will stretch a whole size more. For instance, I have a 30-inch waist and I ended up having to get a 28-inch waist because I could put my fist down the 30-inch jeans. My fist shouldn't be able to go down my pants, on many levels.

Now here is the problem with walking into a Gap store to buy the denim legging, at least my local Gap. There are not a lot of sizes available including the standard run of 0-10. So, I was forced to buy the size I wanted (6/28) online, which I don't like to do; but since this time I enjoyed a lovely online discount, I shan't complain too much. What I will complain about is the uninformed and slightly insolent customer service that I run into there.

Tidbit about Gap: Gap generally has a scant, unstylish selection of clothing for women, but two to three times a year there is a timeless must-have piece that deserves attention. These jeggings are one of them.

This is a very strong, thick glass jar and complies with ASTM 2179 AND 2147 testing methods. (Ensures glass is able to withstand heat and has no cracks or fractures)

Measurements: Height 7.5cm, Width 7.5cm.

Approximate Volume: 150mls

Finish: Black inner spray*

We recommend 2mm Cotton Wicks for this jar.

* As theses candle jars have undergone a water soluble paint finish, (rather than a solvent finish) they are more prone to scratching, so please take care when handling the jars. Washing, soaking and immersing the candle jars in soapy water will soften and deteriorate the finish. Use only a DRY – soft cloth (microfibre is best) to remove dust, prior to filling. The water soluble paint finish performs just like coloured glass during burning.
