Allelopathic Effect of Convolvulus arvensis L. Extracts on The Phytohormones and Cytological Processes of Zea mays L. Seeds

The effects of different methanol extracts of Convolvulus arvensis on phytohormones (indole acetic acid (IAA), gibberellic acid (GA), abscisic acid (ABA) and salicylic acid (SA)) levels of corn were investigated.

Phytohormones

It was observed that all concentrations of methanol extracts (50 µl, 75 µl, 100 µl) of roots, stems and leaves of C. arvensis decreased the mitotic index and also caused abnormalities in chromosomes.

On the other hand, phytohormone levels have been changed by application of different extracts at various concentrations. Compared with the control, GA levels decreased significantly whereas ABA levels increased in all the application groups.

Effect of Knee-Ankle-Foot Orthosis (KAFO) on Knee Kinematics and Kinetics in an Individual with Knee Varus Alignment

The medial compartment knee osteo arthritis (OA) is the most affected location for OA. The main knee biomechanics changes which are associated with the medial compartment knee OA are less knee flexion value (the normal mean maximum knee flexion has been shown to be 64.6° during walking, 98.6° during ascending, and 90.3 °during descending), high knee varus angle and an increased the external knee adduction moment(EKAM) during walking and stairs climbing due to shifting the knee joint centre more laterally and the centre of the load medially.

Knee-Ankle-Foot Orthosis
These changes lead to pain during daily activities and progression of the knee OA. The EKAM is considered as the most important variable in the frontal plan and has two peaks: The first peak is a sharp one after initial contact during early stance phase, while the second one is in the late stance phase. The first peak is affected by the amount of knee varus, joint space narrowing, OA severity, and progression level, while the second one is more correlated to the amount of toe out and pain levels.

Direct Shoot Organogenesis from Juvenile Cotyledon of Jatropha podagrica Hook

Jatropha podagrica is a shrub commonly known as coral nut, Guatemala Rhubarb and physic nut; and it belongs to family Euphorbiaceae. It is a tropical America innate, but similarly common in southern part of Africa, Australia and warmer portions of Asia.

Jatropha podagrica Hook
Jatropha originate from “jatros” the Greek word which means doctor also ‘‘trophe’’ food, that suggests the therapeutic practises. J. podagrica under the tribe Joannesieae of the family Euphorbiaceae comprises about 165-170 identified types worldwide primarily in tropical and subtropical areas. Jatropha is a tremendously adaptive plant thus it can grow in dry lands and degraded soils. J. podagrica is a very significant plant. It is a rich source of biologically active compounds, used for antimicrobial activities. It is also a famous ornamental plant and most remarkably, a promising biodiesel plant. Some of the many secondary metabolites extracted from J. podagrica are scoparone, 3-Acetylaleuritolic acid, fraxidin, japodic acid and erythrinasinate.

Averaged and Personalized Mathematical Modeling of Biomechanics of a System Limb-Orthosis

Despite the growing use of orthoses in clinic, sports and everyday life, and availability of a number of medical guides and atlases for orthoses the line of activity, involvingmechanical and mathematical modeling of "Leg-Orthosis" system, is as yet only at the beginning of its development.

Orthosis
Publications relating to modeling limbs orthotics per se (biomechanics of foot and insoles constitutes actually a separate independent area of research) by methods of solid mechanics, are isolated yet, and they relate only to orthosis itself and completely ignore the very limb and its mechanical properties. At the same time such studies are needed to resolve a number of important issues. For example, it is known that the rate of tissue regeneration depends on the loading level and program. It is therefore important to find out whether it is possible to control the limb unloading in an orthosis – for example, through a change in the orthosis lateral compression, etc. Read more>>>>>>>

Sporotrichosis: An Infectious Emerging Mycosis of Zoonotic Potential

Sporotrichosis (Berumann`s disease, peat moss disease, rose gardener’s disease, Schenck`s disease) is an infectious, subcutaneous or chronic granulomatous mycotic disease of humans aswell as animals. It is a life- threatening disease in immune compromised patients.

Sporotrichosis
Sporotrichosis is considered as an emerging zoonotic fungal disease in many regions of the world. An American researcher Benjamin Schenck is credited to identify the organism for the first time in 1898. The presence of asteroid bodies in pus from cutaneous lesions was first time noticed by Slendore in 1908. In 1920, Ghosh described the first case of sporotrichosis from Kolkata, which established the endemic focus of infection in the North-eastern belt of India. The disease is endemic in many regions of the world including India. Sporotrichosis is a disease of occupational risk, affecting agricultural workers, farmers, gardeners, and mine workers.Read more>>>>>

Laterality and Gender in Congenital Upper Limb Deficiencies

Laterality and gender in congenital upper limb deficiencies have been an area of debate in prosthetics for many years. Images such as the ‘Limbless children, Moscow’ in 1993 by GerdLudwig in the National Geographic showed a line of 8 children, all with left sided congenital upper limb deficiency.

Upper Limb Deficiencies
The line consisted of 6 girls and two boys. Did this picture depict what has been considered by the experts to be true when it comes to congenital upper limb deficiencies – It is more common on the left side and more common in females? A bias towards more left upper limb congenital absences has been commented on in a number of papers in the late 90’s. There appeared to be no conclusive explanation for this preponderance. A paper by Corballis and Morgan in 1979 suggested that the developing embryo is under the influence of a left-right maturational gradient which seems to favour earlier or more rapid development on the left than the right.

Hadronic Radiation of Biological Molecules

As hadronic radiation therapy becomes an ever more important treatment method for various forms ofcarcinogenesis, it becomes ever more important to understand the interaction of fast, heavy, ions, such as protons or alpha particles, with biologically significant molecules.

Biological Molecules
In general, this implies understanding of the transfer of the kinetic energy of the incoming ion to electronic energy of the target molecule, which can subsequently lead to fragmentation, and thus loss of function, of the carcinogen target. The use of hadronic radiation projectiles instead of X-rays has a large advantage in modern times, as the energy deposited by hadronic projectiles is much more localized than that from X-rays. Thus, energy from the radiation can be much more accurately focused on the carcinogenic area.

Usage of Pedorthics in Managing Diabetic Foot

Diabetes is no more the developed countries disease, it has spread its roots equally in the developing country, like in India. Diabetes and its complications are now rapidly becomingthe second threat to human longevity.

Diabetic Foot

There are different types of diabetes, but the common affected areas in all cases start with the foot. The insensate foot leads to the largest trend of amputation. Abnormal pressure on the insensate foot plays an important role in the pathogenesis of diabetic foot ulcers. Failure to relieve pressure is the main cause of non-healing diabetic ulcers. Generally, people on a common note feel that wearing footwear prevents and cures diabetes. But different studies have shown that about 83% of diabetic subjects did not wear appropriate footwear. The common foot disorders start with the collapse of the normal foot arch or generally referred to as the flat foot type.

Human-Sloth Bear Conflict: Causes and Mitigation Measures in Kota,Rajasthan

Human-Sloth Bear Conflict

The sloth bear (Melursus ursinus) is now considered as endangered by IUCN red list of 2011. In wild habitat it is considered as the most dangerous wild animal because it is unpredictable and often attacks on human in forests.

In the present investigation human sloth bear conflicts were studied in Kota district of Rajasthan, using forest department records, interviews with villagers and surveys within sloth bear habitat. Most of the casualties can be reduced by restricting human entries into sloth bear habitats, avoiding camping and housing in their habitats especially near water sources.


Road accidents are also very common in the present study area as there is a National Highway near the forest area. Active management with local inhabitants will support the conservation of sloth bear.
