Schizophrenia, Not a Psychotic Disorder: Bleuler Revisited

(View Complete Item Description)

Current diagnostic criteria delineate schizophrenia as a discrete entity essentially defined by positive symptoms. However, the role of positive symptoms in psychiatry is being questioned. There is compelling evidence that psychotic manifestations are expressed in the population in a continuum of varying degrees of severity, ranging from normality to full-blown psychosis. In most cases, these phenomena do not persist, but they constitute risk factors for psychiatric disorders in general. Psychotic symptoms are also present in most non-psychotic psychiatric diagnoses, being a marker of severity. Research revealed that hallucinations and delusions appear to have distinct, independent biological underpinnings—in the general population, in psychotic, and in non-psychotic disorders as well. On the other hand, negative symptoms were seen to be far more restricted to schizophrenia, have other underlying pathophysiology than positive symptoms, predict outcome and treatment response in schizophrenia, and start before the first psychotic outbreak. The current work discusses the concept of schizophrenia, suggesting that a greater emphasis should be put on cases where psychotic symptoms emerge in a premorbid subtly increasing negative/cognitive symptoms background. In those cases, psychosis would have a different course and outcome while psychosis occurring in the absence of such background deterioration would be more benign—probably having no, or a milder, underlying degenerative process. This reformulation should better drive psychopathological classification, face positive symptoms as epiphenomenon of the schizophrenia process, and dishevel stigma from schizophrenia and from delusions and hallucinations.

Mutation Breeding

(View Complete Item Description)

It is well known that mutation is the ultimate source of variation. Without adequate variation, plant breeding is impossible. To start a breeding program, the breeder must find the appropriate genotype (containing the desired genes) from existing variation, or create the variation if it is not found in nature. Mutagenesis is the process by which new alleles are created. The purpose of this chapter is to discuss mutagenesis as both a technique and a breeding method. The newly created mutants may be used as parents in future breeding programs, in which case mutagenesis is a breeding technique as a source of variation. However, an induced mutant can be systematically processed through conventional breeding steps to be released as a cultivar, hence making it a breeding method (mutation breeding). Mutations arise spontaneously in nature and are pivotal in natural evolution.

PHARMACOLOGY OF PLANT IMMUNOMODULATORS

(View Complete Item Description)

The immunomodulators or Rasayana’s (in Ayurveda) are agents used to modulate the immune system and can be obtained from both natural as well as synthetic origin from plants and chemicals respectively. The aim of this review is to highlight the work on pharmacological aspects of plant immunomodulators and also provides the knowledge on the recent pharmacological research update in current year (2011). Plants explained in this review having potential of immunomodulating activity are identified from various sources in the literature. Among these many plants have undergone in vitro as well as in vivo evaluations which are explained in this review including the dose administered of particular plant extract and the mechanism involved in immunomodulation.

A Review on Fruits Having Anti-Diabetic Potential

(View Complete Item Description)

Diabetes mellitus is a metabolic disorder of the endocrine system. The disease occurs worldwide and its incidence is increasing rapidly in most parts of the world. Moreover, continuous use of the synthetic anti-diabetic drugs causes side effects and toxicity. Therefore, seeking natural and non-toxic anti-diabetic drugs is necessary for diabetic therapy. Medicinal fruits play an important role in the development of potent therapeutic agents. The present paper reviews the data reported on pharmacologically active phytoconstituents obtained from fruits involved in anti-diabetic activity along with pharmacological status which have been experimentally studied for hypoglycaemic activity. This work stimulates the researchers for further research on the potential use of medicinal fruits having anti-diabetic potential.
