Family: Brassicaceae
Genus: Arabis
Species:A. alpina
Kingdom: Plantae
Order: Brassicales

Common Names: Alpine Rock Cress, Alpine rockcress

Habitat : Arabis alpina is native to Europe. In Britain it is only found on the Isle of Skye. It grows on the screes and rocks in moist sites in mountains.

Description:
Arabis alpina is a perennial plant. The stems grow up to 40 cm (16 inches) tall, and are topped with loose heads of white, four-petalled flowers. The leaves in the basal rosette are long, strongly toothed and clearly stalked, although the stem leaves are stalkless and clasp the stem.

It is not frost tender. It is in flower from Mar to May, and the seeds ripen in June. The flowers are hermaphrodite (have both male and female organs) and are pollinated by Bees, lepidoptera, self.The plant is self-fertile.
Cultivation:
Easily grown in ordinary well-drained soil. Prefers a sandy loam and a sunny position. Another report says that it prefers partial shade[134]. Plants resent root disturbance and are best put in their final positions whilst still small. The flowers are attractive to bees.
Propagation:
Seed – it is best to surface sow the seed as soon as it is ripe in a light position in a cold fram. Seed can also be sown in spring. It usually germinates in 2 – 3 weeks at 21°c. When large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. Division after flowering. Very easy, the divisions can be planted out straight into their permanent positions if required. Cuttings in a shady border in summer.

Edible Uses: ...Young leaves – cooked or raw. An agreeable cress-like flavour. Flowers – raw or cooked. A cress-like flavour.

Medicinal Uses: Could not find anywhere.
Other Uses:
Best when massed as a ground cover in rock gardens, on slopes or cascading over a stone wall. May also be used in the border front as an edging plant. A good compliment to early spring bulbs such as Narcissus.

Taxonomy:
A. alpina is believed to have originated in Asia Minor about 2 million years ago. From there it migrated twice into East Africa (500,000 years ago) where it grows today on the high East African mountains in the ericaceous belt. Another migration route led A. alpina into Europe which was then colonised periglacially. In genetic terms, the highest diversity is found in Asia Minor. In central and northern Europe, A. alpina seems to be genetically quite uniform .

There is growing interest to develop Arabis alpina as a model organism for genetics, population genetics, and molecular biology. The first genetic linkage map has been created and the first phenotypes, especially perenniality, are tackled by QTL mapping.

It is in flower from June to September, and produces seeds from August to October. The inflorescence forms a terminal spike and is composed of dense whorls of white or pale pink flowers. The calyx has five lobes and the corolla forms a two-lipped flower about 4 mm (0.16 in) long with a fused tube. The upper lip of each flower is slightly convex with a notched tip and the lower lip is three-lobed, the central lobe being the largest and bearing a red “nectar mark” to attract pollinating insects. There are two stamens, the gynoecium has two fused carpels and the fruit is a four-chambered schizocarp. Its carpels float which may aid dispersal of the plant and its rhizomeous roots also allow the plant to spread.

Cultivation:
Tolerates most soil types so long as they are wet. Grows well in shallow water. Succeeds in sun or shade.

Propagation:
Seed – sow spring or autumn in a cold frame. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in the greenhouse for their first year. Plant them out into their permanent positions in early summer. Division in spring or autumn. Larger clumps can be replanted direct into their permanent positions, though it is best to pot up smaller clumps and grow them on in a cold frame until they are rooting well. Plant them out in the spring.

Edible Uses:

Edible Parts: Root.  Root – raw or cooked. A famine food, it is only used when all else fails

Iyengar yoga improves immunity

A study, conducted by researchers at the Washington State University, has found that the immunity
system of breast cancer survivors improved significantly after practising the Iyengar form of yoga.

CLICK & SEE

Created by B K S Iyengar, based on the traditional eight limbs of yoga as expounded by Patanjali in his Yoga Sutras, this yoga form emphasises the development of strength, stamina, flexibility and balance, as well as concentration and meditation.

Considered to be a more active form of yoga, researchers reported on Monday at the American Physiological Society meeting in Washington DC that in breast cancer survivors, the Iyengar method not only promoted psychological well-being but also benefited the patients’ immune system.

According to lead researcher Pamela E Schultz, practising the yoga form resulted in decreased activation of an important immune system protein called NF-kB in patients, which is a marker of stress in the body.
“So it’s possible,” Schultz said, “that decreased activation of NF-kB indicates decreased stress in the body. NF-kB is activated in the body by physical or mental stress.”

Schultz randomly assigned 19 women, average age 61 years, diagnosed with stage I-III breast cancer and receiving antiestrogen or aromatase inhibitor hormonal therapy, to eight weeks of Iyengar yoga. Beginning level Iyengar yoga classes were conducted two times per week for eight weeks and included the following yoga poses: standing poses, chest and shoulder openers and inversions.

Blood sample to determine lymphocyte NF-kB activation were collected prior to and following the intervention.
“Psychosocial tests showed that the demands of illness, which reflects the burden of hardship of being a breast cancer survivor, lowered in the yoga participants. The survivors showed changes in the way their immune cells respond to activation signals. The function of genes in immune cells can be regulated by proteins called transcription factors. Transcription factor nuclear factor-kappa B (NF-kB) is linked to immune cell activation and to the stress response,” Schultz said.

Speaking to TOI, 89-year-old Iyengar said, “Similar studies in Mumbai found that certain asanas improve the quality of blood and results in better blood circulation. It also improved the production of proteins in the immune system called T-cell receptors that actually direct the immune system to attack specific targets. Immune cells that contain the engineered T-cell receptor better display targeted immunity with a few asanas.”

Cancer and its treatments are associated with considerable distress, impaired quality of life and reduced physical function, especially for women with breast cancer who receive multi-modality treatment over an extended period of time. “Yoga greatly helps to relieve and improve quality of life among cancer patients over time,” Iyengar said.

Dr Chidanand Murthy, director of Central Council for Research in Yoga, said, “A similar study conducted in AIIMS on 30 patients in 2006 found that Sudarshan Kriya and Pranayama greatly helped cut down the growth of breast cancer cells within the body. Through release of stress, adverse effects of chemotherapy were also avoided.”

Indian Council of Medical Research data shows that the incidence of breast cancer is high among Indians and is estimated that one in 22 Indian females is likely to develop breast cancer during her lifetime in contrast to one in eight in America.

According to Delhi’s latest cancer registry, breast cancer among women is rising by about 2% every year. It now affects 30 per 100,000 females.
