Aconitum: Need for sustainable exploitation (with special reference to Uttarakhand)
Srivastava Nidhi,Sharma Vikas,Kamal Barkha,Jadon Vikash
International Journal of Green Pharmacy , 2010,
Abstract: Red Data Book has a long list of many endangered medicinal plants in which genus Aconitum, known as monkshood, wolfsbane, Devil′s helmet or blue rocket, belonging to the family Ranunculaceae finds a key position. There are over 250 species of Aconitum. These herbaceous perennial plants are chiefly natives of the mountainous parts of the Northern Hemisphere and are characterised by significant and valuable medicinal properties. Illegal and unscientific extraction from the wild has made the important species of this genus endangered. This review focuses on the importance and medicinal uses of the genus (on the basis of literature cited from different Books and Journals and web, visits to the sites and questionnaires), which have been documented and practiced on the basis of traditional as well as scientific knowledge. The review further presents an insight on the role of conventional and modern biotechnological methods for the conservation of the said genus, with special reference to Uttarakhand. Further, it is suggested that the policies of government agencies in coordination with the local bodies, scientists, NGOs and end-users be implemented for the sustainable conservation of Aconitum.
Influence of Pre-Sowing Treatments on in vitro Seed Germination of Ativisha (Aconitum heterophyllum Wall) of Uttarakhand
Nidhi Srivastava,Vikas Sharma,Anoop K. Dobriyal,Barkha Kamal
Biotechnology , 2011,
Abstract: In the present study in-vitro seed germination protocol using various pre-sowing treatments for Aconitum heterophyllum Wall intended for its ex-situ conservation was optimized. Temperature requirement for seed germination in this species was optimized under controlled conditions which revealed that low temperature of 15C (p<1.0%) was obligatory. Two in-vitro presowing treatments: PST-1 (pre-treated seeds kept at normal room temperature) and PST-2 (pre-treated seeds kept at 15C) were also studied. Highest seed germination was recorded with PST-2 (p<0.1%) with 0.5 mg L-1 IAA (97.17%) as compared to PST-1 (p<1.0%). As seed embryo in A. heterophyllum Wall is small, it requires low temperature to grow and also GA3 (100 and 200 M) could not improve the seed germination even at low temperature; so it may be assumed that it exhibit deep complex morphophysiological dormancy (MPD).

Biotechnology , 2010,
Abstract: The present review is the pragmatic approach to ensue the findings on almost every aspect of very important herbal genus Aconitum, as a number of species belonging to this genus are renowned for their medicinal benefits in Ayurvedic, Unani, Chinese and Tibetan system of medicine. A lot of important attribute have been assigned to the species of this genus. Numerous works has been done on its various aspects from cultivation, conservation, phytochemical and pharmacological analysis to molecular characterization. The important species of this genus which have been explored so far include A. heterophyllum, A. carmichaelii, A. balfourii, A. napellus, A. anthora, A. laeve and A. kusnezoffii.

Benign migratory glossitis Report of two cases
Shobha B V,Barkha N
Indian Journal of Dental Advancements , 2011, DOI: 10.5866/3.4.705
Abstract: Benign migratory glossitis (BMG) or geographic tongue is a benign condition in which asymptomatic smooth erythematous patches with discrete borders appear on the dorsum of the tongue. The condition usually is discovered on routine clinical examination. This ulcer like lesion may recur at different sites on the tongue, creating a migratory appearance and mostly resolves completely. This article presents two cases of BMG, one in a four year old child with mild symptoms and other as asymptomatic in 40 year old adult .The patients presented with a classical clinical picture of ulcer like regions on the dorsum of the tongue with loss of filiform papilla.
Power Flow Comparisons in a Transmission Line with UPFC and SSSCs Devices
Barkha Rajpurohit,Anil Kumar Chaudhary
International Journal of Advanced Electrical and Electronics Engineering , 2013,
Abstract: The device SSSCs work in the same way as the STATCOM. It has a voltage source converter (VCS) connected in series to the transmission line through a transformer. It required an energy source to provide a continuous voltage through a condenser and to compensate the losses of the VSC. A SSSC is able to exchange active and reactive power with the transmission system. In this case the serial injected voltage can delay or advanced the line current. This means that the SSSC can be uniformly controlled in any value. In this paper the result thus we obtained by modeling a transmission system in MATLAB SIMULINK by using UPFC and SSSCs (static synchronous series compensator) in first case the upfc is connected to bus B3 and in second case upfc is replaced by sssc and the result obtained from these two case is compared. From these two simulink results we conclude that the sssc gives more suitable results as compared to UPFC.
Dressing after Dressing: Sadra’s Interpretation of Change  [PDF]
Muhammad Kamal
Open Journal of Philosophy (OJPP) , 2013, DOI: 10.4236/ojpp.2013.31009
Abstract:

This paper deals with the doctrine of transubstantial change advocated by Mulla Sadra in which substances as well as accidents are thought to be in constant and gradual change. Against Aristotle’s doctrine of accidental change, Mulla Sadra argues that no stable ground can bring about change and since substance is renewable it cannot carry identity of a changing existent. Here we investigate whether identity is possible or not. If it is possible then what becomes a ground for establishing identity of changing substances.

Aliskiren Augments the Activities of Anti-Oxidant Enzymes in Liver Homogenates of DOCA Salt-Induced Hypertensive Rats  [PDF]
Sahar Kamal
Advances in Enzyme Research (AER) , 2014, DOI: 10.4236/aer.2014.22010
Abstract: Hypertension is a serious problem that is recently thought to be associated with damaging effects on target organs partially via oxidative stress. On the other hand, there is accumulating literature describing some sort of therapeutic interaction between antioxidant enzymes in vital organs and hypertension. Therefore, the aim of this study is to investigate the possible effect of a direct renin inhibitor, aliskiren, used in treatment of hypertension via renin-angiotensin-aldosterone system (RAAS), on selected anti-oxidant enzymes in hepatic homogenates in DOCA salt-induced hypertesnive albino rats. Thirty male wister albino rats were assigned randomly into 3 groups (n = 10/ group). Group 1 received no treatement and serves as control. Group 2 received 0.5% carboxymethylcellulose sodium ip as a solvent of aliskiren, as a direct renin inhibitor (DRI). Group 3 received aliskiren 100 mg/kg/day ip for 4 weeks through gastric tube. Systolic blood pressure (SBP) was measured every week and its mean was recorded at the end of the study. Superoxide dismutase (SOD) enzyme in RBCs lysates, activities of catalase (CAT) and glutathione peroxidase enzymes and thiobarbituric acid reactive substance (TBARS), as a marker of lipid peroxidation, in hepatic homogenates were measured at the end of the study. DRI produced a marked reduction in mean SBP of hypertensive rats. It also significantly (p < 0.05) increased the activities of measured anti-oxidant enzymes while it significantly (p < 0.05) reduced TBARS in liver homogenates. These results indicated that renin possesses an oxidative effect in the liver in hypertensive rats. Aliskiren, in addition to its powerful anti-hypertensive effect, it could induce a great anti-oxidant effect in liver homogenates of DOCA salt-hypertensive rats.
Individual Essences in Avicenna’s Metaphysics  [PDF]
Muhammad Kamal
Open Journal of Philosophy (OJPP) , 2014, DOI: 10.4236/ojpp.2014.41004
Abstract:

Central to Aristotle’s metaphysics is the question of individuality. The individuality of each substance is explained in relation to matter because the form is universal. Avicenna, as one of the Aristotelian Neoplatonist philosophers, is not content with this explanation and proposes to establish individuality on other grounds. In this paper, I argue that in his perspective it is not the matter which determines individuality but rather the principle of existence.

 

Metal-Like Gravity and Its Cosmological Applications  [PDF]
Kamal Barghout
Journal of Modern Physics (JMP) , 2014, DOI: 10.4236/jmp.2014.518211
Abstract: Modification to Newton gravitational interaction is presented. It provides an understanding of a novel universal gravitational field of particle origin that defines alternative attributes to elementary constituents of matter particles and the gravitational interactions between them. It investigates gravitational relationship between two types of mass. The model assigns Coulombic gravitational interaction to DM particles and baryons by attributing self-antigravity to both normal matter and dark matter (DM). It defines the interaction as like particles repel while unlike particles attract. Metal-like force is proposed where same type mass (baryons) are gravitationally attracted to each other when a sea of DM particles are attracted to them and glue them together analogous to a metal bond. At close range, other dominant forces take place such as electromagnetic force. In light of this model, intergalactic self-repulsive DM particles are proposed to result in accelerating expansion of the universe. The model produces flat rotational curves for spiral galaxies and provides a physical explanation to MOND theory.
