Six fibre degrading fungus were isolated from rumen of mithun (Bos frontalis) at National Research Centre on Mithun, Jharnapani, Medziphema, Nagaland using specific media for rumen fungus. These isolated fungal cultures showed higher fibre degrading enzymes like CM cellulase, Xylanase and Avicelase activity. Addition of fungal culture in the mixed rumen liquor of mithun increased in vitro gas production. The identification and characterization of these isolates was done by DNA isolation, Polymerase Chain Reaction (PCR) amplification, sequencing and plotting of phylogenic tree. The result showed that two isolates were homologus to Orpinomyces species and four isolates were homologus to Neocallimastix species. These isolates can have potential to be used as microbial feed additives in ruminants. |

The investigation was done to find out the tissue culture
potentiality of the local rice (Oryza sativa L.) variety Topa,
cultivated mainly in Kishoregonj, the district of Bangladesh. In this
present study, callus induction, callus growth rate and indirect regeneration
potentiality of the variety was examined. One hundred percent callus induction
efficacy was noted when dehusked mature seeds were cultured on MS media
supplemented with 2.0 mg L-1 2, 4-D. After first successive
subculture the highest callus growth rate (0.0791 ±0.017 g week-1)
was observed under the best callus induction media. The highest regeneration
response was recorded at treatment of 3.0 mg L-1 BA+0.5 mg
L-1 NAA+0.5 mg L-1 Kn, which regenerated 80% shoot
with an average of 3 shoots per explant. |

In this study, a typical psycho-neuro-endocrino-immune
network has been developed in which, Corticotrophin Releasing Hormone
(CRH), adrenocorticotrophic hormone (ACTH), glucocorticoids (GC), β-endorphin
(β-end) and met-enkephalin (Met-enk) are found as important endocrine
components and T cells, B cells, monocytes/macrophages, Natural Killer
(NK) cells and their cytokines that is tumor necrosis factor-α (TNF-α),
interferon gamma (IFN-γ) and interleukins such as IL-1, IL-2, IL-4,
IL-6, IL-10, IL-12 etc., are found as important immune components. Finally,
it has been shown that, brief naturalistic stressors have different immune
modulatory activities such as, cause shift of TH1 to TH2 cytokine response
which is harmful to one`s homeostasis and increase disease susceptibility. |

A protocol for mass propagation through axillary bud proliferation was
established for Rauwolfia serpentina L. Benth. (Apocynaceae). MS
medium supplemented with 1.5 mg L-1 BA and 0.2 mg L-1
NAA elicited the maximum number of shoots (4 multiple shoots) from nodal
explants. These adventitious shoots were best rooted on half strength
MS medium supplemented with 1.0 mg L-1 each of IBA and IAA.
The in vitro raised plants were acclimatized in glass house and
successfully transplanted to field condition with almost 95% survival. |

The influence of media composition on
callus induction and subsequent regeneration of Rauwolfia serpentina
L. Benth has been studied. High frequency (96.43%) callus induction was
obtained when nodal segments from in vitro raised shoots were cultured
on MS medium supplemented with 0.5 mg L-1 BA and 2.0 mg L-1
NAA. The callus differentiated into adventitious shoots when it was subcultured
on MS medium supplemented with 2.0 mg L-1 BA with 0.2 mg L-1
NAA. Regenerated shoots were best rooted on half-strength MS medium with
1.0 mg L-1 each of IBA and IAA. |

Cancer is a leading cause of death worldwide. There are a lot of cancer causing agents which are divided as physical carcinogens, chemical carcinogens and biological carcinogens. But most of the carcinogens or causes of cancer are related to our lifestyle like diet, habit, occupation, radiation and some infection, etc. Chemoprevention is highly necessary to prevent cancer related preterm death. For this besides avoiding the causes of cancer we should concentrate ourselves on our diet. Because, numerous phytochemicals derived from edible plants have been reported to interfere with a specific stage of the carcinogenic process. Many mechanisms have been shown to account for the anticarcinogenic actions of dietary constituents and recently attention has been focused on intracellular-signalling cascades as common molecular targets for various chemopreventive phytochemicals. In this study, we tried to describe lifestyle related causes of cancer and the molecular basis of cancer prevention through the phytochemicals. |

Globally, the prevalence of chronic, noncommunicable diseases is increasing at an alarming rate and diabetes is one of them. If diabetes is not controlled then a lot of complication like coronary artery disease, cerebrovascular disease, peripheral vascular disease, retinopathy, nephropathy and neuropathy arise in diabetic patients and causes morbidity and/or mortality. Diabetes is increasing at an epidemic form and in near future the largest increases will take place in the regions dominated by developing economies. So, it will be a great social and economical burden to developing countries as well as the developed. But if we be aware about our diet and lifestyle and take proper medication we may prevent and reduce the prevalence of diabetes. Oral medicine plays an important role in management of diabetes. But most of the oral drugs are costly and have a lot of side effects. For this it is also necessary to take medicines with fewer or no side effects. And antidiabetic medicinal plants may play an important role in this case. In this article we have tried to describe how diet and lifestyle with using medicinal plants may help to prevent or maintain diabetes and help to reduce the mortality and morbidity due to diabetes or complication related to it. |

Traditional medical science has kept the mind separate from the body. Recently people realize the effect of mind on health and psychoneuroimmunology is the new evolved science that describes the interactions between psyche and soma. In this review through a typical psycho-neuro-endocrino-immune network the effects of psychological stress (acute, brief naturalistic and chronic) and relaxation on immune modulation has been shown. From this network Corticotrophin Releasing Factor (CRF), Adrenocorticotrophic Hormone (ACTH), Glucocorticoids (GC), α-endorphin and Met-enkephalin are found as important endocrine components and T cells, B cells, monocytes/macrophages, Natural Killer (NK) cells and their cytokines that is Tumor Necrosis Factor-α (TNF-α), Interferon Gamma (IFN-α) and interleukins such as IL-1, IL-2, IL-4, IL-6, IL-10, IL-12 etc. are found as important immune components. Finally, it has been shown that, acute, brief naturalistic and chronic stress have different immune modulatory activities which are harmful to one’s homeostasis and relaxation can help to maintain that homeostasis. |

Cardio Vascular Disease (CVD) is the number one killer and leading cause of disability among women in most of the developed countries. Several epidemiological studies indicate that women during the fertile age have a lower risk of cardiac events and the female hormone estrogen provides this natural protection. Usually, the protection fades after menopause and this risk increases gradually in the five to ten years after the female hormone estrogen begins to dwindle. Hence, postmenopausal women leaving with untreated risk factors make them vulnerable to develop myocardial infarction, heart failure and sudden cardiac death. In addition, several recently published articles have shown the effect of stress on cardiovascular system and in pathogenesis of myocardial infarction and myocardial ischemia. Moreover, the effect of stress on estrogen level has also been supported by some recently published articles. For these reasons, in this review the possible links among stress, estrogen and CVD in women have been described. |
